PART I.

Items 1 & 2. Business and Properties

General
We are an independent retail energy services company founded in 1999 and now organized as a Delaware corporation that provides residential and commercial customers in competitive markets across the United States with an alternative choice for their natural gas and electricity in competitive markets across the United States. We purchase our natural gas and electricity supply from a variety of wholesale providers and bill our customers monthly for the delivery of electricity and natural gas based on their consumption at either a fixed or variable-price. natural gas and electricity variable price. Electricity and natural gas are then distributed to our customers by local regulated utility companies through their existing infrastructure.
Our business consists of two operating segments:
| | |
| • | Retail Electricity Segment . In this segment, we purchase electricity supply through physical and financial transactions with market counterparties and independent system operators ("ISOs") and supply electricity to residential and commercial consumers pursuant to fixed-price and variable-price contracts. For the years ended December 31, 2017 , 2016 and 2015 , approximately 82% , 76% and 64% , respectively, of our retail revenue were 2018 , 2017 and 2016 , approximately 86% , 82% and 76% , respectively, of our revenue was derived from the sale of electricity. |

| | |
| • | Retail Natural Gas Segment . In this segment, we purchase natural gas supply through physical and financial transactions with market counterparties and supply natural gas to residential and commercial consumers pursuant to fixed-price and variable-price contracts. For the years ended December 31, 2018 , 2017 and 2016 , approximately 14% , 18% and 24% 2017 , 2016 and 2015 , approximately 18% , 24% and 36% , respectively, of our retail revenues were derived from the sale of natural gas. We also identify wholesale natural gas arbitrage opportunities in conjunction with our retail procurement and hedging activities, which we refer to as asset optimization. |

See Note 15 "Segment Reporting" to the Company's audited consolidated financial statements in this report for financial information relating to our operating segments.

Recent Developments

See "Management's Discussion and Analysis of Financial Condition and Results of Operations-Recent Developments" for a discussion of recent developments affecting our business and operations.

Our Operations

As of December 31, 2018 , we operated in 94 utility service territories across 19 states and the District of Columbia and had approximately 908,000 RCEs. An RCE, or residential customer equivalent, is an industry standard measure of natural gas or electricity usage with each RCE representing annual consumption of 100 MMBtu of natural gas or 10 MWh of electricity. We serve natural gas customers in fifteen states (Arizona, California, Colorado, Connecticut, Florida, Illinois, Indiana, Maryland, Massachusetts, Michigan, Nevada, New Jersey, New York, Ohio and Pennsylvania) and electricity customers in twelve states (Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Ohio, Pennsylvania and Texas) and the District of Columbia using nine brands (Spark Energy, CenStar Energy, Electricity Maine, ENH Power, Major Energy, Oasis Energy,eleven brands (CenStar Energy, Electricity Maine, Electricity N.H., HIKO Energy, Major Energy, Oasis Energy, Perigee Energy, Provider Power Mass, Respond Power, Spark Energy, and Verde Energy). During 2018, we began reducing the number of brands through which we conduct operations with a goal of reducing the number of separate brands to six by the end of 2019.

Customer Contracts and Product Offerings

Fixed and variable-price contracts

We offer a variety of fixed-price and variable-price service options to our natural gas and electricity customers. Under our fixed-price service options, our customers purchase natural gas and electricity at a fixed price over the

life of the customer contract, which provides our customers with protection against increases in natural gas and electricity prices. Our fixed-price contracts typically have a term of one to two years for residential customers and up to three years for commercial customers, and most provide for an early termination fee in the event that the customer terminates service prior to the expiration of the contract term. In a typical market, we offer fixed-price electricity plans for 6, 12 and 24 months and fixed-price natural gas plans from 12 to 24 months, which may come with or without a monthly service fee and/or a termination fee. Our variable-price service options carry a month-to-month term and are priced based on our forecasts of underlying commodity prices and other market factors,

including the competitive landscape in the market and the regulatory environment, and may also include a monthly service fee. We also offer variable-price natural gas and electricity plans that offer an introductory fixed price that is generally applied for a certain number of billing cycles, typically two billing cycles in our current markets, then switches to a variable price based on market conditions. Our variable plans may or may not provide for a termination fee, depending on the market and customer type.

As of December 31, 2018 , approximately 53% of our natural gas RCEs were fixed-price, and the remaining 47% were variable-price. As of December 31, 2018 , approximately 81% of our electricity RCEs were fixed-price, and the remaining 18% of our electricity RCEs were variable-price.19% were variable-price.

The fixed/variable splits of our RCEs were as follows as of December 31, 2018 :

Green products and renewable energy credits

We offer renewable and carbon neutral ("green") products in certain markets. Green energy products are a growing market opportunity and typically provide increased unit margins as a result of improved customer satisfaction and less competition. Renewable electricity products allow customers to choose electricity sourced from wind, solar, hydroelectric and biofuel sources, through the purchase of renewable energy credits ("RECs"). Carbon neutral natural gas products give customers the option to reduce or eliminate the carbon footprint associated with their energy usage through the purchase of carbon offset credits. These products typically provide for fixed or variable prices and generally follow the terms of our other products with the added benefit of carbon reduction and reduced environmental impact. We currently offer renewable electricity in all of our electricity markets and carbon neutral natural gas in several of our gas markets.

In addition to the RECs we purchase to satisfy our voluntary requirements under the terms of our green contracts with our customers, we must also purchase a specified number of RECs based on the amount of electricity we sell in a state in a year pursuant to individual state renewable portfolio standards. We forecast the price for the required RECs at the end of each month and incorporate this cost component into our customer pricing models.

Customer Acquisition and Retention

8

Table of Contents

Our customer acquisition strategy consists of customer growth obtained through traditional organic customer acquisitions, complemented by opportunistic sales channels complemented by customer and business acquisitions. We make decisions on how best to deploy capital on customer acquisitions based on a variety of factors, including cost to acquire customers, availability of opportunities and our view of attractive commodity pricing in particular regions.For example, we may seek to make an acquisition of a large number of customers in a particular group of markets even though the initial acquisition cost may be higher because long-term margins are higher. We expect to focus on organic growth through 2018.

Table of Contents

Organic Growth

We use organic sales strategies are used to both maintain and grow our customer base by offering competitive pricing, price certainty, and/or green product offerings. We manage growth on a market-by-market basis by developing price curves in each of the markets we serve and comparing the market prices to the price offered by the local regulated utility. is offering. We then determine if there is an opportunity in a particular market based on our ability to create an attractive customer value proposition that is also able to enhance our profitabilitya competitive product on economic terms that provides customer value and satisfies our profitability objectives. The attractiveness of a product from a consumer's standpoint is based on a variety of factors, including overall pricing, price stability, contract term, sources of generation and environmental impact and whether or not the contract provides for termination and other fees. Product pricing is also based on a several other factors, including the cost to acquire customers in the market, the competitive landscape and supply issues that may affect pricing.

Once a product has been created for a particular market, we then develop a marketing campaign using a combination of sales channels. with an emphasis on door-to-door and web-based marketing. We identify and acquire customers through a variety of additional sales channels, including our inbound customer care call center, outbound calling, online marketing, opt-in web-based leads, email, direct mail, door-to-door sales, affinity programs, direct sales, brokers and consultants. For residential customers, we primarily use indirect sales brokers, web based solicitation, door-to-door sales, outbound calling, and other methods. For 2018 , the largest channels were door-to-door sales, web-based, and outbound telemarketing. For C&I customers, which are typically larger and have greater natural gas and electricity requirements, we typically use brokers or direct marketing to obtain these customers. At December 31, 2018 , our customer base was 55% residential and 45% C&I customers. In our sales practices, online marketing, email, direct mail, brokers and direct sales we typically employ multiple vendors under short-term contracts and have not entered into any exclusive marketing arrangements with sales vendors. Our marketing team continuously evaluates the effectiveness of each customer acquisition channel and makes adjustments in order to achieve targeted growth and manage customer acquisition costs. We attempt to maintain a disciplined approach to recovery of our customer acquisition costs within defined periods.

Acquisitions

We actively monitor acquisition opportunities that may arise in the domestic acquisition market, and seek to
acquire both portfolios of customers as well as retail energy companies utilizing some combination of cash and borrowings under our Senior Credit Facility, the issuance of common or preferred stock, or other financing arrangements. with our Founder and his affiliates.

We are actively monitoring acquisition opportunities that may arise in the domestic acquisition market as smaller retailers face difficulties in managing risk and liquidity issues caused by the recent extreme weather patterns. Our ability to grow at historic levels may be constrained if the market for acquisition candidates is limited and we are unable to make acquisitions of portfolios of customers and retail energy companies on commercially reasonable terms. Please see "Risk Factors" - risks related to our Business and Our Industry - We may be subject to risks in connection with acquisitions, which could cause us to fail to realize many of the anticipated benefits of such acquisition and "Risk Factors - Risks Related to Our Capital Stock - We engage in transaction with our affiliates and expect to do so in the future. The terms of such transactions.and the resolution of any conflict that may arise may not always be in our or our stockholders' best interest."
Please see "Risk Factors" for a discussion of risks related to our acquisition strategy and ability to finance such transactions.


Growth Sources and Sales Channels

During the year ended December 31, 2017 , our RCE acquisitions were generated from the following sources and sales channels:
| |
| | | |
| Indirect Sales Brokers | 30 | % |
| Acquisitions | 25 | % |
| Web Based | 14 | % |
| Door to Door | 13 | % |
| Outbound | 5 | % |
| Other | 13 | % |

Table of Contents

In 2017, we grew our commercial and industrial ("C&I") customer base. C&I customers typically have larger natural gas and electricity volume requirements, but at lower margins than residential customers. These C&I customers also typically have longer contract terms. After significant growth in our C&I customer count in 2017, management is rebalancing our mix of customers in the first part of 2018 to focus on higher margin residential customers. At December 31, 2017, approximately 48% of the Company's RCEs were C&I customers.

Retaining customers and maximizing customer lifetime value

Following the acquisition of a customer, we devote significant attention to customer retention. We have developed a disciplined renewal communication process, which is designed to effectively reach our customers prior to the end of the contract term, and employ a team dedicated to managing this renewal communications process. Customers are contacted in each utility prior to the expiration of the customer's contract. We may contact the customer through additional channels such as outbound telephone calls and electronic mail communication. We encourage retention and promote renewals by means of each of these contact methods.calls or email.

We also apply a proprietary evaluation and segmentation process to optimize value to both to us and the customer. We analyze historical usage, attrition rates and consumer behaviors to specifically tailor competitive products that aim to maximize the total expected return from energy sales to a specific customer, which we refer to as customer lifetime value.

Investment in ESM

The Company and Spark HoldCo, together with In 2016, we and eREX Co., Ltd., a Japanese company, entered into a joint venture investment in eREX Spark Marketing Co., Ltd ("ESM"). Operations for ESM began on April 1, 2016 in connection with the deregulation of the Japanese power market. As of December 31, 2018 , we have contributed 156.4 million Japanese Yen, or $1.4

Table of Contents

million , for a 20% ownership interest in ESM. As of December 31, 2018 , ESM has approximately 119,000 customers, which are currently excluded from our count of RCEs.

Commodity Supply

We hedge and procure our energy requirements from various wholesale energy markets, including both physical and financial markets, through short- and long-term contracts. Our in-house energy supply team is responsible for managing our commodity positions (including energy procurement, capacity, transmission, renewable energy, and resource adequacy requirements) within our risk management policies. We procure our natural gas and electricity requirements at various trading hubs, city gates and load zones. When we procure commodities at trading hubs, we are responsible for delivery to the applicable local regulated utility for distribution.

In most markets, we hedge our electricity exposure with financial products and then purchase the physical power directly from the ISO for delivery. Alternatively, we may use physical products to hedge our electricity exposure rather than buying physical electricity in the day-ahead market from the ISO. During the year ended December 31, 2018 , we transacted physical and financial settlement of electricity with approximately 16 suppliers.

We are assessed monthly for ancillary charges such as reserves and capacity in the electricity sector by the ISOs. For example, the ISOs will charge all retail electricity providers for monthly reserves that the ISO determines are necessary to protect the integrity of the grid. We attempt to estimate such amounts, but they are difficult to estimate because they are charged in arrears by the ISOs and are subject to fluctuations based on weather and other market conditions. Many of the utilities we serve also allocate natural gas transportation and storage assets to us as a part of their competitive choice program. We are required to fill our allocated storage capacity with natural gas, which creates commodity supply and price risk. Sometimes we cannot hedge the volumes associated with these assets because they are too small compared to the much larger bulk transaction volumes required for trades in the wholesale market or it is not economically feasible to do so.

We periodically adjust our portfolio of purchase/sale contracts in the wholesale natural gas market based upon continual analysis of our forecasted load requirements. Natural gas is then delivered to the local regulated utility city-gate or other specified delivery points where the local regulated utility takes control of the natural gas and delivers it to individual customer locations. Additionally, we hedge our natural gas price exposure with financial products. During the year ended December 31, 2018 , we transacted physical and financial settlement of natural gas with approximately 82 wholesale counterparties.

We also enter into back-to-back wholesale transactions to optimize our credit lines with third-party energy suppliers. With each of our third-party energy suppliers, we have certain contracted credit lines, within which we are able to purchase energy supply from these counterparties. If we desire to purchase supply beyond these credit limits, we are required to post collateral in the form of either cash or letters of credit. As we begin to approach the limits of our credit line with one supplier, we may purchase energy supply from another supplier and sell that supply to the original counterparty in order to reduce our net position with that counterparty and open up additional credit to procure supply in the future. Our sales of gas pursuant to these activities also enable us to optimize our credit lines with third-party energy suppliers by decreasing our net buy position with those suppliers.

Asset Optimization

Part of our business includes asset optimization activities in which we identify opportunities in the wholesale natural gas markets in conjunction with our retail procurement and hedging activities. Many of the competitive pipeline choice programs in which we participate require us and other retail energy suppliers to take assignment of and manage natural gas transportation and storage assets upstream of their respective city-gate delivery points. In our allocated storage assets, we are also obligated to buy and inject gas in the summer season (April through October) and sell and withdraw gas during the winter season (November through March). These purchase and injection obligations in our allocated storage assets injection and purchase obligations require us to take a seasonal long position in natural gas. Our asset optimization group determines

whether market conditions justify hedging these long positions through additional derivative transactions.

Our asset optimization group utilizes these allocated transportation and storage assets for retail customer usage and to effect transactions in the wholesale market based on market conditions and opportunities. Our asset optimization group also contracts We also contract with third parties for transportation and storage capacity in the wholesale market and are responsible for reservation and demand charges attributable to both our allocated and third-party contracted transportation and storage assets. Our asset optimization group utilizes these allocated and third-party transportation and storage assets in a variety of ways to either improve profitability or optimize supply-side counterparty credit lines.

We frequently enter into spot market transactions in which we purchase and sell natural gas at the same point or we purchase natural gas at one point or pool and ship it using our pipeline reservations for sale at another point or pool, in each case location and ship it using our pipeline capacity for sale at another location, if we are able to capture a margin. We view these spot market transactions as low risk because we enter

Table of Contents

into the buy and sell transactions simultaneously on a back-to-back basis. We will also act as an intermediary for market participants who need assistance with short-term procurement requirements. Consumers and suppliers will contact us with a need for a certain quantity of natural gas to be bought or sold at a specific location. When this occurs, we are able to use our contacts in the wholesale market to source the requested supply and we will capture a margin in these transactions.

The asset optimization group historically entered into long-term transportation and storage transactions. Our risk policies require that this business is Our risk policies require that optimization activities be limited to back-to-back purchase and sale transactions, or open positions subject to our aggregate net open position limits, which are not held for a period longer than two months. Furthermore, all additional capacity procured outside of a utility allocation of retail assets must be approved by a risk committee. Hedges of our firm transportation obligations are limited to two years or less and hedging of interruptible capacity is prohibited.

We also enter into back-to-back wholesale transactions to optimize our credit lines with third-party energy suppliers. With each of our third-party energy suppliers, we have certain contracted credit lines, within which we are able to purchase energy supply from these counterparties. If we desire to purchase supply beyond these credit limits, we are required to post collateral, in the form of either cash or letters of credit. As we begin to approach the limits of our credit line with one supplier, we may purchase energy supply from another supplier and sell that supply to the original counterparty in order to reduce our net buy position with that counterparty and open up additional credit to procure supply in the future. Our sales of gas pursuant to these activities also enable us to optimize our credit lines with third-party energy suppliers by decreasing our net buy position with those suppliers.

Commodity Supply

We hedge and procure our energy requirements from various wholesale energy markets, including both physical and financial markets and through short and long term contracts. Our in-house energy supply team is responsible for managing our commodity positions (including energy procurement, capacity, transmission, renewable energy, and resource adequacy requirements) within risk tolerances defined by our Risk Managementpolicies. We procure our natural gas and electricity requirements at various trading hubs, city gates and load zones. When we procure commodities at trading hubs, we are responsible for delivery to the applicable local regulated utility for distribution.
Risk Management

We periodically adjust our portfolio of purchase/sale contracts in the wholesale natural gas market based upon continual analysis of our forecasted load requirements. Natural gas is then delivered to the local regulated utility city-gate or other specified delivery points where the local regulated utility takes control of the natural gas and delivers it to individual customers' locations. Additionally, we hedge our natural gas price exposure with financial products. During the year ended December 31, 2017 , we transacted physical and financial settlement of natural gas with approximately 93 wholesale counterparties.
We operate


In most markets, we typically hedge our electricity exposure with financial products and then purchase the physical power directly from the ISO for delivery. From time to time, we use a combination of physical and financial products to hedge our electricity exposure before buying physical electricity in the day-ahead and real-time market from the ISO. During the year ended December 31, 2017 , we transacted physical and financial settlement of electricity with approximately 17 suppliers.

We are assessed monthly for ancillary charges such as reserves and capacity in the electricity sector by the ISOs. For example, the ISOs will charge all retail electricity providers for monthly reserves that the ISO determines are necessary to protect the integrity of the grid. We attempt to estimate such amounts, but they are difficult to estimate because they are charged in arrears by the ISOs and are subject to fluctuations based on weather and other market conditions. Many of the utilities we serve also allocate natural gas transportation and storage assets to us as a part of their competitive choice program. We are required to fill our allocated storage capacity with natural gas, which creates commodity supply and price risk. Sometimes we cannot hedge the volumes associated with these assets because they are too small compared to the much larger bulk transaction volumes required for trades in the wholesale market or it is not economically feasible to do so.

Risk Management

Our management team operates under a set of corporate risk policies and procedures relating to the purchase and sale of electricity and natural gas, general risk management and credit and collections functions. Our in-house energy supply team is responsible for managing our commodity positions (including energy, procurement, capacity, transmission, renewable energy, and resource adequacy requirements) within risk tolerances defined by our risk management policies. We attempt to increase the predictability of cash flows by following our various hedging strategies.

Our risk committee has control and authority over all of our risk management activities. The risk committee establishes and oversees the execution of our credit risk management policy and our commodity risk policy. The risk management policies are reviewed at least annually and the risk committee typically meets quarterly to assure that we have followed its policies. The risk committee also seeks to ensure the application of our risk management policies to new products that we may offer. The risk committee is comprised of our Chief Executive Officer and our Chief Financial Officer, who meet on a regular basis to review the status of the risk management activities and positions. Our risk team reports directly to our Chief Financial Officer and their compensation is unrelated to trading activity. Commodity positions are typically reviewed and updated daily based on information from our customer databases and pricing information sources. The risk policy sets volumetric limits on intra-day and end of day long and short positions in natural gas and electricity. With respect to specific hedges, we have established and approved a formal delegation of authority specifying each trader's authorized volumetric limits based on instrument type, lead time (time to trade flow), fixed price volume, index price volume and tenor (trade flow) for individual transactions. The risk team reports to the risk committee any hedging transactions that exceed these delegated transaction limits. A discussion of the various risks we face in our risk management activities is as follows:

Commodity Price and Volumetric Risk

Because our contracts require that we deliver full natural gas or electricity requirements to many of our customers and because our customers' usage can be impacted by factors such as weather, we may periodically purchase more or less commodity than our aggregate customer volumetric needs. In buying or selling excess volumes, we may be exposed to commodity price volatility. In order to address the potential volumetric variability of our monthly deliveries for fixed-price customers, we implement various hedging strategies to attempt to mitigate our exposure.

Our commodity risk management strategy is designed to hedge substantially all of our forecasted volumes on our fixed-price customer contracts, as well as a portion of the near-term volumes on our variable-price customer

10

Table of Contents

contracts. We use both physical and financial products to hedge our fixed-price exposure. The efficacy of our risk management program may be adversely impacted by unanticipated events and costs that we are not able to effectively hedge, including abnormal customer attrition and consumption, certain variable costs associated with electricity grid reliability, pricing differences in the local markets for local delivery of commodities, unanticipated events that impact supply and demand, such as extreme weather, and abrupt changes in the markets for, or availability or cost of, financial instruments that help to hedge commodity price.

Variability in customer demand is primarily impacted by weather. We use utility-provided historical and/or forward projected customer volumes as a basis for our forecasted volumes and mitigate the risk of seasonal volume fluctuation for some customers by purchasing excess fixed-price hedges within our volumetric tolerances. Should seasonal demand exceed our weather-normalized projections, we may experience a negative impact on our financial results.

In addition to our forward price risk management approach described above, we may From time to time, we also take further measures to reduce price risk and optimize our returns by: (i) maximizing the use of natural gas storage in our daily balancing market areas in order to give us the flexibility to offset volumetric variability arising from changes in winter demand; (ii) entering into daily swing contracts in our daily balancing markets over the winter months to enable us to increase or decrease daily volumes if demand increases or decreases; and (iii) purchasing out-of-the-money call options for contract periods with the highest seasonal volumetric risk to protect against steeply rising prices if our

13

Table of Contents

customer demands exceed our forecast. Being geographically diversified in our delivery areas also permits us, from time to time, to employ assets not being used in one area to other areas, thereby mitigating potential increased costs for natural gas that we otherwise may have had to acquire at higher prices to meet increased demand.

We utilize NYMEX-settled financial instruments to offset price risk associated with volume commitments under fixed-price contracts. The valuation for these financial instruments is calculated daily based on the NYMEX Exchange published closing price, and they are settled using the NYMEX Exchange's published settlement price at their maturity.

Basis Risk

We are exposed to basis risk in our operations when the commodities we hedge are sold at different delivery points from the exposure we are seeking to hedge. For example, if we hedge our natural gas commodity price with Chicago basis but physical supply must be delivered to the individual delivery points of specific utility systems around the Chicago metropolitan area, we are exposed to the risk that prices may differ between the Chicago delivery point and the individual utility system delivery points. These differences can be significant from time to time, particularly during extreme, unforecasted cold weather conditions. Similarly, in certain of our electricity markets, customers pay the load zone price for electricity, so if we purchase supply to be delivered at a hub, we may have basis risk between the hub and the load zone electricity prices due to local congestion that is not reflected in the hub price. We attempt to hedge basis risk where possible, but hedging instruments are occasionally not economically feasible or available in the smaller quantities that we require.

Customer Credit Risk

Our credit risk management policies are designed to limit customer credit exposure. Credit risk is managed through participation in purchase of receivables ("POR") programs in utility service territories where such programs are available. In these markets, we monitor the credit ratings of the local regulated utilities and the parent companies of the utilities that purchase our customer accounts receivable. We also periodically review payment history and financial information for the local regulated utilities to ensure that we identify and respond to any deteriorating trends. In non-POR markets, we assess the creditworthiness of new applicants, monitor customer payment activities and administer an active collection program. Using risk models, past credit experience and different levels of exposure in each of the markets, we monitor our receivable aging, bad debt forecasts and actual bad debt expenses and continually adjust as necessary.


11

Table of Contents

In territories where
In many of the utility services territories where we conduct business, POR programs have been established, whereby the local regulated utility purchases our receivables, and then becomes responsible for billing the customer and collecting payment from the customer. In return for their assumption of risk, we receive slightly discounted proceeds on the receivables sold. POR programs result in substantially all of our credit risk being linked to the applicable utility and not to our end-use customer in these territories. For the year ended December 31, 2018 , approximately 66% of our retail revenues were derived from territories in which substantially all of our credit risk was directly linked to local regulated utility companies, all of which had investment grade ratings. as of such date. During the same period, we paid these local regulated utilities a weighted average discount of approximately 1.0% of total revenues for customer credit risk. In certain of the POR markets in which we operate, the utilities limit their collections exposure by retaining the ability to transfer a delinquent account back to us for collection when collections are past due for a specified period. If our subsequent collection efforts are unsuccessful, we return the account to the local regulated utility for termination of service. Under these service programs, we are exposed to credit risk related to payment for services rendered during the time between when the customer is transferred to us by the local regulated utility and the time we return the customer to the utility for termination of service, which is generally one to two billing periods. We may also realize a loss on fixed-price customers in this scenario due to the fact that we will have already fully hedged the customer's expected commodity usage for the life of the contract.

In non-POR markets (and in select POR markets where we may choose to direct bill our customers), we manage commercial customer credit risk through a formal credit review and manage residential customer credit risk through a variety of procedures, which may include credit score screening, deposits and disconnection for non-payment. We

14

Table of Contents

also maintain an allowance for doubtful accounts, which represents our estimate of potential credit losses associated with accounts receivable from customers within these markets.

We assess the adequacy of the allowance for doubtful accounts through review of an aging of customer accounts receivable and general economic conditions in the markets that we serve. Our bad debt expense for the year ended December 31, 2018 was $10.1 million , or 1.0% of retail revenues. See "Management's Discussion and Analysis of Financial Condition and Results of Operations-Drivers of Our Business-Customer Credit Risk" for a more detailed discussion of our bad debt expense for the year ended December 31, 2018 .

We do not have high concentrations of sales volumes to individual customers. For the year ended December 31, 2018 , our largest customer accounted for less than 1% of total retail energy sales volume.

Counterparty Credit Risk in Wholesale Markets

We do not independently produce natural gas and electricity and depend upon third parties for our supply, which exposes us to wholesale counterparty credit risk in our retail and asset optimization activities. If the counterparties to our supply contracts are unable to perform their obligations, we may suffer losses, including those that occur as a result of being unable to secure replacement supplies of natural gas or electricity on a timely or cost-effective basis or at all. At December 31, 2018 , approximately $4.1 million of our total exposure of $22.7 million was either with a non-investment grade counterparty or otherwise not secured with collateral or a guarantee.

Operational Risk

As with all companies, we are at risk from cyber-attacks (breaches, unauthorized access, misuse, computer viruses, or other malicious code or other events) that could materially adversely affect our business, or otherwise cause interruptions or malfunctions in our operations.

We mitigate these risks through multiple layers of security controls including policy, hardware, and software security solutions. We also have engaged third parties to assist with both external and internal vulnerability scans and continually enhance awareness through employee education and accountability. As of December 31, 2018 , we have not experienced any material loss related to cyber-attacks or other information security breaches.

Relationship with our Founder and Majority Shareholder

We have historically leveraged our relationship with affiliates of our founder, chairman and majority shareholder, W. Keith Maxwell III (our "Founder"), to execute on our growth strategy, which includes sourcing of acquisitions, financing, support, and operating cost efficiencies. To support. this relationship, Our Founder formed our strategy, including sourcing acquisitions, financing, and operations support. Our Founder owns National Gas & Electric, LLC, an affiliate of the Company ("NG&E"), which was formed for the purpose of purchasing retail energy companies and retail customer books that may ultimately be resold to the Company. This relationship affords us access to opportunities that might not otherwise be has afforded us access to opportunities that may not have otherwise been available to us due to our size and availability of capital.

On March 7, 2018, we entered into an asset purchase agreement with NG&E pursuant to which we will acquire approximately 50,000 RCEs from NG&E for a cash purchase price of $250 for each RCE, or approximately $12.5 million in the aggregate. Please see "Management's Discussion and Analysis of Financial Condition and Results of Operations-Recent Developments-Acquisition of Customers from NG&E." For a summary of historical acquisitions with our Founder and NG&E, please see "-Customer Acquisition and Retention-Acquisitions."

We may engage in additional transactions with NG&E in the future We currently expect that we would fund any future transactions with NG&E with some and expect that any such transactions would be funded by a combination of cash, subordinated debt, or the issuance of Class A common stock or Class B common stock. to NG&E.

Given our Founder's significant economic interest in us, we believe that he is incentivized to offer us opportunities, to grow through this drop-down structure. However, our Founder Although we believe our Founder would be incentivized to offer us additional acquisition opportunities, he and his affiliates are under no obligation to do so, and we are under no obligation to buy assets from them. Additionally, as we grow and our access to capital and opportunities improves, we may rely less upon NG&E as a source of acquisitions and seek to enter into more transactions directly with third parties. Any acquisition activity involving NG&E or any other affiliate of our Founder will be subject to negotiation and approval by a special committee of our Board of Directors consisting solely of independent directors. Please see "Risk Factors-Risks related to Our Business and Our Industry-We may be subject to risks in connection with acquisitions, which could cause us to fail to realize many of the anticipated benefits of such acquisitions and "Risk Factors-Risks Related to Our Capital Stock-We engage in Factors" related to acquisitions and transactions with our affiliates.and expect to do so in the future.

Master Service Agreement

we entered into
a Master Service Agreement (the "Master Service Agreement") effective January 1, 2016 with Retailco Services, LLC ("Retailco Services"), which is wholly owned by our Founder. The Master Service Agreement is for a one-year term and renews automatically for successive one-year terms unless the Master Service Agreement is terminated by either party. On January 1, 2018, the Master Service agreement, renewed automatically pursuant to its terms for a one year period ending on December 31, 2018. with an affiliated company wholly owned by our Founder. Under this agreement, we were provided

Retailco Services provides us with operational support services such as: enrollment and renewal transaction services; customer billing and transaction services; electronic payment processing services; customer services and information technology infrastructure and application support services under the Master Service Agreement (collectively, the "Services"). Spark HoldCo pays Retailco Services (collectively, the "Services"). We paid our affiliate a monthly fee consisting of a monthly fixed fee plus a variable fee per customer per month depending on market complexity. Effective April 1, 2018, we terminated the Master Services Agreement. For a further discussion of transactions with affiliates, see Part II, Financial Statements and Supplementary Data, Note 15 "Transactions with Affiliates." we meet with Retailco Services quarterly to discuss fees and Service Levels (as defined below) based on changes in assumptions; to date, we have not adjusted fees or the Service Levels. the Master Service Agreement provides that Retailco Services perform the Services in accordance with specified service levels (the "Service Levels"), and in the event Retailco Services fails to meet the Service Levels, Spark HoldCo receives a credit against invoices or a cash payment (the "Penalty Payment"). The amount of the Penalty Payment was initially limited to $0.1 million monthly, but adjusts annually based upon the amount of fees charged by Retailco Services for Services over the prior year. Furthermore, in the event that the Service Levels are not satisfied and Spark HoldCo suffers damages in excess of $0.5 million as a result of such failure, Retailco Services will make a payment (the "Damage Payment") to Spark HoldCo for the amount of the damages (less the amount of any Penalty Payments also due). The Master Service Agreement. provides that in no event may the Penalty Payments and Damage Payments exceed $2.5 million in any twelve-month period.

In connection with the Master Service Agreement, certain of Spark HoldCo's employees who previously provided services similar to those to be provided under the Master Service Agreement became employees of Retailco Services, and certain contracts, assets, and intellectual property were assigned to Retailco Services. In addition, in order to facilitate the Services, Spark HoldCo granted Retailco Services a non-transferable, non-exclusive, royalty-free, revocable and non-sub-licensable license to use certain of its intellectual property.

Either Spark HoldCo or Retailco Services is permitted to terminate the Master Service Agreement: (a) upon 30 days prior written notice For convenience and without cause; (b) upon a material breach and written notice to the breaching party when the breach has not been cured 30 days after such notice; (c) upon written notice if Retailco Services is unable for any reason to resume performance of the services within 60 days following the occurrence of an event of force majeure; and (d) upon certain events of insolvency, assignment for the benefit of creditors, cessation of business, or filings of petitions for bankruptcy or insolvency proceedings by the other party. In the event the Master Service Agreement is terminated for any reason, Retailco Services will provide certain transition services to Spark HoldCo following the termination, not to exceed six months at the then-current fees.

Retailco Services and Spark HoldCo have agreed to indemnify each other from: (a) willful misconduct or negligence of the other; (b) bodily injury or death of any person or damage to real and/or tangible personal property caused by the acts or omission of the other; (c) any breach of any representation, warranty, covenant or other obligation of the other party under the Master Service Agreement, and (d) other standard matters. Subject to certain exceptions (including indemnification obligations, the obligations to pay fees and the Damage Payments and Penalty Payments), each parties' liability is limited to $2.5 million of direct damages. NuDevco Retail has entered into the Master Service Agreement for the limited purpose of guarantying payments that Retailco Services may be required to make under the Master Service Agreement up to a maximum of $2.0 million .

During the year ended December 31, 2017 and 2016 , the Company recorded general and administrative expenses of $22.0 million and $14.7 million , respectively, in connection with the Master Service Agreement. For the years ended December 31, 2017 and 2016 , Penalty Payments totaled $0.1 million , and Damage Payments totaled zero and $1.4 million , respectively. Additionally, under the Master Service Agreement, we capitalized $0.7 million and $1.3 million , respectively, during the years ended December 31, 2017 and 2016 of property and equipment for software and consultant time used in the application, development and implementation of various systems including customer billing and resource management systems.

On March 7, 2018, we, Retailco Services and NuDevco Retail mutually agreed to terminate the Master Services Agreement, effective April 1, 2018.

Competition

The markets in which we operate are highly competitive. In markets that are open to competitive choice of retail energy suppliers, our primary competition comes from the incumbent utility and other independent retail energy companies. In the electricity sector, these competitors include larger, well-capitalized energy retailers such as Direct Energy Inc., FirstEnergy Solutions, Inc., Just Energy Group, Inc., and NRG Energy, Inc.,Calpine Energy Solutions, LLC, Constellation Energy Group, Inc., Direct Energy, Inc., NRG Energy, Inc., and Vistra Energy Corp. We also compete with small local retail energy providers in the electricity sector that are focused exclusively on certain markets. Each market has a different group of local retail energy providers. In the natural gas sector, our national competitors are primarily Direct Energy and Constellation Energy. Our national competitors generally have diversified energy platforms with multiple marketing approaches and broad geographic coverage similar to us. Competition in each market is based primarily on product offering, price and customer service. The number of competitors in our markets varies. In well-established markets in the Northeast and Texas we have hundreds of competitors, while in others the competition is limited to several participants.

The competitive landscape differs in each utility service area and within each targeted customer segment. Over the last several years, a number of utilities have spun off their retail marketing arms as part of the opening of retail competition in these markets. Markets that offer POR programs are generally more competitive than those markets in which retail energy providers bear customer credit risk.Market participants are significantly shielded from bad debt expense, thereby allowing easier entry into the POR markets. In these markets, we face additional competition as barriers to entry are less onerous.

Our ability to compete by increasing our market share depends on our ability to convince customers to switch to our products and services, and our ability to offer products at attractive prices. Many local regulated utilities and their affiliates may possess the advantages of name recognition, longer operating histories, long-standing relationships with their customers and access to financial and other resources, which could pose a competitive challenge to us. As a result of these advantages, many customers of these local regulated utilities may decide to stay with their longtime energy provider if they have been satisfied with their service in the past. In addition, competitors may choose to offer more attractive short-term pricing to increase their market share.

Seasonality of Our Business


13

Table of Contents

Our overall operating results fluctuate substantially on a seasonal basis depending on: (i) the geographic mix of our customer base; (ii) the relative concentration of our commodity mix; (iii) weather conditions, which directly influence the demand for natural gas and electricity and affect the prices of energy commodities; and (iv) variability in market prices for natural gas and electricity. These factors can have material short-term impacts on monthly and quarterly operating results, which may be misleading when considered outside of the context of our annual operating cycle.

Our accounts payable and accounts receivable are impacted by seasonality due to the timing differences between when we pay our suppliers for accounts payable versus when we collect from our customers on accounts receivable. We typically pay our suppliers for purchases of natural gas on a monthly basis and electricity on a weekly basis. However, it takes approximately two months from the time we deliver the electricity or natural gas to our customers before we collect from our customers on accounts receivable attributable to those supplies. This timing difference affects our cash flows, especially during peak cycles in the winter and summer months.

Natural gas accounted for approximately 14% of our retail revenues for the year ended December 31, 2018 , which exposes us to a high degree of seasonality in our cash flows and income earned throughout the year as a result of the high concentration of heating load in the winter months. We utilize a considerable amount of cash from operations and borrowing capacity to fund working capital, which includes inventory purchases from April through October each year. We sell our natural gas inventory during the months of November through March of each year. We expect that the significant seasonality impacts to our cash flows and income will continue in future periods.

Regulatory Environment

We operate in the highly regulated natural gas and electricity retail sales industry in all of our respective jurisdictions, and must comply with the legislation and regulations in these jurisdictions in order to maintain our licensed status and to continue our operations, and licenses to operate. We must also comply to obtain the necessary licenses in jurisdictions in which we plan to compete. Licensing requirements vary by state, but generally involve regular, standardized reporting in order to maintain a license in good standing with the state commission responsible for regulating retail electricity and gas suppliers. There is potential for changes to state legislation and regulatory measures addressing licensing requirements that may impact our business model in the applicable jurisdiction. In addition, as further discussed below, our marketing activities and customer enrollment procedures are subject to rules and regulations at the state and federal levels, and failure to comply with requirements imposed by federal and state regulatory authorities could impact our licensing in a particular market.

As of October 2015, the state of Connecticut no longer allows retail energy providers to offer variable rate plans even after the customer rolls off of a fixed rate plan. As a result of this change, we now offer customers who end their fixed terms with another fixed term of no less than four billing cycles. This regulatory change did not have a significant impact on our results of operations, and we expect that we can continue to manage the renewals In these markets to maintain profitability. Other states are currently examining the effectiveness of implementing such a restriction.
In


On February 23, 2016, the New York State Public Service Commission ("NYPSC") issued an order (the "Reset Order") resetting retail energy markets that, among other things, would have limited the types of competitive products that energy service companies ("ESCOs"), such as us, could offer in New York. The Reset Order stated that all new customer enrollments or expiring agreements for mass market (residential and certain small commercial) customers must enroll or re-enroll in a contract that offers either: (i) a guarantee that the customer will pay no more than what the customer would pay as a full service utility customer, or (ii) an electricity product that is at least 30% derived from specific renewable sources either in the State of New York or in adjacent market areas. In July 2016, most of the Reset Order, including the provisions previously noted, was vacated by a New York state court.

In July 2017, the New York State Supreme Court, Appellate Division, Third Department ruled to uphold the lower court's ruling overturning portions of the Reset Order because the NYPSC did not follow the proper

18

Table of Contents

process in issuing the Reset Order. However, the court also determined that the NYPSC has authority to set ESCO rates and take other action consistent with the Resetting Order as long as the proper administrative process is followed. The NYPSC conducted evidentiary proceedings to determine what the regulatory framework for ESCOs in New York would be going forward, which concluded in late 2017. Briefing on these hearings is due by April 30, 2018. We believe that the administrative law judges overseeing the proceeding will provide for settlement discussions before adjudication of the matter. There can be no assurance that settlement discussions between the NYPSC and ESCOs will occur, or if such discussions occur, that they There can be no assurance that this process will result in a commercially reasonable framework for ESCOs to operate in New York. See "Risk Factors-We face risks due to increasing regulation of the retail energy industry at the state level."

In addition, in connection with the Low-Income Order promulgated by the NYPSC in December of 2016, the New York State Supreme Court, Appellate Division, Third Department ruled in September 2017 that ESCOs must proceed with returning existing low-income customers to utility service and stop enrolling new low-income customers. The ESCO's have effectively exhausted their legal remedies to appeal this matter and must now comply with the Low-Income Order. ESCOs may continue serving low income customers if those customers are enrolled in longer term gift-term or guaranteed savings arrangements fixed arrangements with guaranteed savings or with value add inclusions (that were entered into prior to the effective date of the Low-Income Order) or if the ESCO receives a waiver from the NYPSC to provide low-income customers with guaranteed savings. The Company and its subsidiaries have been returning low-income customers to the applicable utilities in the next twelve months as they roll off of their contracts. These as they have rolled off of their contracts. As of December 31, 2018 , remaining low-income customers represent approximately less than 1% of our total customer count as of December 31, 2017 .3% of our total RCEs in New York and 0.5% of our RCEs overall.

We are evaluating the potential impact of the NYPSC's Reset Order and subsequent proceedings on our New York operations while preparing to operate in compliance with any new requirements that may come as a result of any new order promulgated by the NYPSC. Given the uncertainty of the outcome of these matters and the final requirements that may be implemented, we are unable to predict at this time whether it will have a significant long-term impact on our operations in New York.

More recently, on October 15, 2018, the Attorney General for the Commonwealth of Massachusetts filed suit against another ESCO and others alleging unfair or deceptive acts or practices in violation of a consumer protections act, breach of the covenant of good faith and fair dealing, and violation of the Massachusetts Telemarketing Solicitation Act. Contemporaneously with the filing of their complaint, the Commonwealth filed for injunctive relief seeking to attach purchase of receivables program revenues owed to the ESCO as possible damages. There can be no assurance that the Commonwealth will not pursue similar claims against other ESCOs.

Recently, certain state commissions have begun efforts to restrict the ability of retail suppliers to "pass through" costs to customers associated with certain changes in law or regulatory requirements. For example, on January 22, 2019, the New Jersey Board of Public Utilities (NJ BPU) sent a cease and desist letter to third party suppliers (TPS) in New Jersey instructing that a TPS may not charge a customer rate that is higher than the fixed rate applicable during the period for which that rate was fixed. The letter notified TPS that such increases were prohibited and instructed TPS to refund customers amounts charged in excess of the applicable fixed rate. Parties have challenged the NJ BPU's letter and it is not clear at this time whether refunds will be required. Similarly, the Connecticut Public Utilities Regulatory Authority (PURA) recently opened a docket after receiving complaints regarding increases by suppliers to certain fixed-price supplier contracts due to change in law triggers. PURA will consider whether suppliers' actions constitute unfair and deceptive trade practices or otherwise violates applicable laws. PURA is expected to issue a declaratory ruling following its review. Depending on the outcome of these efforts in New Jersey and Connecticut, the Company may be required to assume costs that it otherwise would pass on to customers under its change in law provisions and potentially provide refunds to certain customers.

Our marketing efforts to consumers, including but not limited to telemarketing, door-to-door sales, direct mail and online marketing, are subject to consumer protection regulation including state deceptive trade practices acts, Federal Trade Commission ("FTC") marketing standards, and state utility commission rules governing customer solicitations and enrollments, among others. By way of example, telemarketing activity is subject to federal and state do-not-call regulation and certain enrollment standards promulgated by state regulators. Door-to-door sales are governed by the FTC's "Cooling Off" Rule as well as state-specific regulation in many jurisdictions. In markets in which we conduct customer credit checks, these checks are subject to the requirements of the Fair Credit Reporting Act. Violations of the rules and regulations governing our marketing and sales activity could impact our license to operate in a particular market, result in suspension or otherwise limit our ability to conduct marketing activity in certain markets, and potentially lead to private actions against us. Moreover, there is potential for changes to legislation and regulatory measures applicable to our marketing measures that may impact our business models.

Recent interpretations of the Telephone Consumer Protection Act of 1991 (the "TCPA") by the Federal Communications Commission ("FCC") have introduced confusion regarding what constitutes an "autodialer" for purposes of determining compliance under the TCPA. Also, additional restrictions have been placed on wireless

telephone numbers making compliance with the TCPA more costly. See "Risk Factors-Risks Related to Our Business and Our Industry-Liability under the TCPA has increased significantly in recent years, and we face risks if we fail to comply."
As compliance with the TCPA gets more costly and as door-to-door marketing becomes increasingly risky both from a regulatory compliance perspective and from the risk of such activities drawing class action litigation claims, we and our peers who rely on these sales channels will find it more difficult than in the past to engage in direct marketing efforts. In response to these risks, we are experimenting with new technologies, such as ringless messaging and door-to-door sales using tablets both of which expand a web-based application to process door-to-door sales enrollments with direct input by the consumer. This application can be accessed using tablets or any smart phone device, which enhances and expands the opportunities to market directly to customers.

Our participation in natural gas and electricity wholesale markets to procure supply for our retail customers and hedge pricing risk is subject to regulation by the Commodity Futures Trading Commission (the "CFTC"), including regulation

Table of Contents

pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act. In order to sell electricity, capacity and ancillary services in the wholesale electricity markets, we are required to have market-based rate authorization, also known as "MBR Authorization", from the Federal Energy Regulatory Commission ("FERC"). We are required to make status update filings to FERC to disclose any affiliate relationships and quarterly filings to FERC regarding volumes of wholesale electricity sales in order to maintain our MBR Authorization. We are also required to seek prior approval by FERC to the extent any direct or indirect change in control occurs with respect to entities that hold MBR Authorization.

The transportation and sale for resale of natural gas in interstate commerce are regulated by agencies of the U.S. federal government, primarily FERC under the Natural Gas Act of 1938, the Natural Gas Policy Act of 1978 and regulations issued under those statutes. FERC regulates interstate natural gas transportation rates and service conditions, which affects our ability to procure natural gas supply for our retail customers and hedge pricing risk. Since 1985, FERC has endeavored to make natural gas transportation more accessible to natural gas buyers and sellers on an open and non-discriminatory basis. FERC's orders do not attempt to directly regulate natural gas retail sales. As a shipper of natural gas on interstate pipelines, we are subject to those interstate pipelines' tariff requirements and FERC regulations and policies applicable to shippers.

Changes in law and to FERC policies and regulations may adversely affect the availability and reliability of firm and/or interruptible transportation service on interstate pipelines, and we cannot predict what future action FERC will take. We do not believe, however, that any regulatory changes will affect us in a way that materially differs from the way they will affect other natural gas marketers and local regulated utilities with which we compete.

In December 26, 2007, FERC issued Order 704, a final rule on the annual natural gas transaction reporting requirements, as amended by subsequent orders on rehearing. Under Order 704, wholesale buyers and sellers of more than 2.2 million MMBtus of physical natural gas in the previous calendar year, including natural gas gatherers and marketers, are required to report, on May 1 of each year, aggregate volumes of natural gas purchased or sold at wholesale in the prior calendar year to the extent such transactions utilize, contribute to, or may contribute to the formation of price indices. It is the responsibility of the reporting entity to determine which individual transactions should be reported based on the guidance of Order 704. Order 704 also requires market participants to indicate whether they report prices to any index publishers, and if so, whether their reporting complies with FERC's policy statement on price reporting. As a wholesale buyer and seller of natural gas, we are subject to the reporting requirements of Order 704.

Employees

We employed 176 people as of December 31, 2017 . This number does not include employees of Retailco Services who provide services to us under the Master Service Agreement as described under "Relationship with Our Founder and Majority Shareholder-Master Service Agreement."2018 , none of which were subject

Item 1A. Risk Factors
You should carefully consider the risks described below together with the other information contained in this Annual Report on Form 10-K. If any of the risks below were to occur, our business, financial condition, cash flows, results of operation and ability to pay dividends on our Class A common stock and Series A Preferred Stock could be adversely impacted, and the price of the Class A common stock and Series A Preferred Stock could decline and you could lose your investment.
Risks Related to Our Business and Our Industry
We are subject to commodity price risk.
Our financial results are largely dependent on the prices at which we can acquire the commodities we resell. The prevailing market prices for natural gas and electricity have historically, and may continue to fluctuate substantially over relatively short periods of time. Changes in market prices for natural gas and electricity may result from many factors that are outside of our control, including:the following:
| | |
| - | weather conditions; |
| | |
| - | seasonality; |
| | |
| - | demand for energy commodities and general economic conditions; |
| | |
| - | disruption of natural gas or electricity transmission or transportation infrastructure or other constraints or inefficiencies; |
| | |
| - | reduction or unavailability of generating capacity, including temporary outages, mothballing, or retirements; |
| | |
| - | the level of prices and availability of natural gas and competing energy sources, including the impact of changes in environmental regulations impacting suppliers; |
| | |
| - | the creditworthiness or bankruptcy or other financial distress of market participants; |
| | |
| - | changes in market liquidity; |
| | |
| - | natural disasters, wars, embargoes, acts of terrorism and other catastrophic events; |
| | |
| - | significant changes in the pricing methods in the wholesale markets in which we operate; |
| | |
| - | changes in regulatory policies concerning how markets are structured, how compensation is provided for service, and the kinds of different services that can or must be offered; |
| | |
| - | federal, state, foreign and other governmental regulation and legislation; and |
| | |
| - | demand side management, conservation, alternative or renewable energy sources. |

We may not be able to pass along changes to the prices we pay to acquire commodities and that we are not able to pass along to our customers.could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.to our customers.
Our financial results may be adversely impacted by weather conditions.
Weather conditions directly influence the demand for and availability of natural gas and electricity and affect the prices of energy commodities. Generally, on most utility systems, demand for natural gas peaks in the winter and demand for electricity peaks in the summer. Typically, when winters are warmer or summers are cooler, demand for energy is lower than expected, resulting in less natural gas and electricity consumption than forecasted. When demand is below anticipated levels due to weather patterns, we may be forced to sell excess supply at prices below our acquisition cost, which could result in reduced margins or even losses.
Conversely, when winters are colder or summers are warmer, consumption may outpace the volumes of natural gas and electricity against which we have hedged, and we may be unable to meet increased demand with storage or swing supply. In these circumstances, we may experience reduced margins or even losses if we are required to purchase additional supply at higher prices. We may fail to accurately anticipate demand due to fluctuations in weather or to effectively manage our supply in response to a fluctuating commodity price environment.could

materially and adversely affect our business, financial condition, cash flows and results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.

Our risk management policies and hedging procedures may not mitigate risk as planned, and we may fail to fully or effectively hedge our commodity supply and price risk.
To provide energy to our customers, we purchase commodities in the wholesale energy markets, which are often highly volatile. Our commodity risk management strategy is designed to hedge substantially all of our forecasted volumes on our fixed-price customer contracts, as well as a portion of the near-term volumes on our variable-price customer contracts. We use both physical and financial products to hedge our exposure. The efficacy of our risk management program may be adversely impacted by unanticipated events and costs that we are not able to effectively hedge, including abnormal customer attrition and consumption, certain variable costs associated with electricity grid reliability, pricing differences in the local markets for local delivery of commodities, unanticipated events that impact supply and demand, such as extreme weather, and abrupt changes in the markets for, or availability or cost of, financial instruments that help to hedge commodity price.
We are exposed to basis risk in our operations when the commodities we hedge are sold at different delivery points from the exposure we are seeking to hedge. For example, if we hedge our natural gas commodity price with Chicago basis but physical supply must be delivered to the individual delivery points of specific utility systems around the Chicago metropolitan area, we are exposed to basis risk between the Chicago basis and the individual utility system delivery points. These differences can be significant from time to time, particularly during extreme, unforecasted cold weather conditions. Similarly, in certain of our electricity markets, customers pay the load zone price for electricity, so if we purchase supply to be delivered at a hub, we may have basis risk between the hub and the load zone electricity prices due to local congestion that is not reflected in the hub price. We attempt to hedge basis risk where possible, but hedging instruments are sometimes not economically feasible or available in the smaller quantities that we require.
Additionally, assumptions that we use in establishing our hedges may reduce the effectiveness of our hedging instruments. Considerations that may affect our hedging policies include, but are not limited to, human error, assumptions about customer attrition, the relationship of prices at different trading or delivery points, assumptions about future weather, and our load forecasting models.
In addition, we incur costs monthly for ancillary charges such as reserves and capacity in the electricity sector by ISOs. For example, the ISOs will charge all retail electricity providers for monthly reserves that the ISO determines are necessary to protect the integrity of the grid. We attempt to estimate such amounts but they are difficult to estimate because they are charged in arrears by the ISOs and are subject to fluctuations based on weather and other market conditions. We may be unable to fully pass the higher cost of ancillary reserves and reliability services through to our customers, and increases in the cost of these ancillary reserves and reliability services could negatively impact our results of operations.
Many of the natural gas utilities we serve allocate a share of transportation and storage capacity to us as a part of their competitive market operations. We are required to fill our allocated storage capacity with natural gas, which creates commodity supply and price risk. Sometimes we cannot hedge the volumes associated with these assets because they are too small compared to the much larger bulk transaction volumes required for trades in the wholesale market or it is not economically feasible to do so. In some regulatory programs or under some contracts, this capacity may be subject to recall by the utilities, which could have the effect of us being required to access the spot market to cover such recall.
If we are unable to effectively manage our risk management policies and hedging procedures, it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class a common stock and Series A Preferred Stock.
a recall.
We face risks due to increasing regulation of the retail energy industry at the state level.

The retail energy industry is highly regulated. Regulations may be changed or reinterpreted and new laws and regulations applicable to our business could be implemented in the future. To the extent that the competitive restructuring of retail electricity and natural gas markets is reversed, altered or discontinued, such changes could have a detrimental impact on our business and overall financial condition.

Some states are beginning to increase their regulation of their retail electricity and natural gas markets in an effort to eliminate deceptive marketing practices. For example, in 2015 the Connecticut Legislature passed legislation providing that licensed electric suppliers in Connecticut could no longer offer variable rate products.

Additionally, the New York Public Service Commission (the "NYPSC") began an aggressive campaign Additionally, the NYPSC launched efforts in 2016 to limit the types of competitive products that ESCOs, such as us, can offer in New York. The NYPSC issued an order (the "Reset Order") requiring that all new customer enrollments or expiring agreements for mass market (residential and certain small commercial) customers must enroll or re-enroll in a contract that offers either: (i) a guarantee that the customer will pay no more than what the customer would pay as a full service utility customer, or (ii) an electricity product that is at least 30% derived from specific renewable sources either in the State of New York or in adjacent market areas. Most of the original Reset Order was vacated by a New York state court in July 2016. However, the ESCOs lost an appeal on the matter of whether the NYPSC has jurisdiction over ESCO pricing of products. Currently, ESCOs and the NYPSC are involved in evidentiary proceedings that are addressing, among other things, whether the NYPSC has sufficient cause to implement regulatory changes similar to those proposed in the Reset Order. In the event that all or significant components of the original resetting Order are re-implemented, Reset Order are implemented, ESCOs, including us, could be obligated to, among other things, drop customers to the utility or seek affirmative consent from their fixed and variable rate customers upon renewal, which may be very difficult to obtain. As of December 31, 2018 , approximately 16% of our customers on an RCE basis were located in New York.

The NYPSC has also successfully implemented a low-income order that requires ESCOs to return existing low-income customers to utility service and stop enrolling new low-income customers unless customers are enrolled in fixed arrangements with guaranteed savings or with value add inclusions (that were entered into prior to the effective date of the low-income order) or if the ESCO receives a waiver from the NYPSC to provide low-income customers with guaranteed savings. As a result of the low-income order, we have been dropping low-income customers back to the applicable utilities in the next twelve months, representing approximately less than 1% of our total customer count as of December 31, 2017 .as they have rolled off of their contracts. As of December 31, 2018 , remaining low-income customers represent approximately 3% of our total RCEs in New York and 0.5% of our RCEs overall.

There can be no assurance that the NYPSC or state regulatory agencies to which we are subject will not continue trying to implement restrictive anti-competitive regulations on us.Any such regulations could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class a common stock and Series a Preferred Stock.

On October 15, 2018, the Attorney General for the Commonwealth of Massachusetts filed suit against certain other ESCOs alleging unfair or deceptive acts or practices in violation of a consumer protections act, breach of the covenant of good faith and fair dealing, and violation of the Massachusetts Telemarketing Solicitation Act. Contemporaneously with the filing of their complaint, the Commonwealth filed for injunctive relief seeking to attach purchase of receivables program revenues owed to the ESCO as possible damages. There can be no assurance that the Commonwealth will not pursue similar claims against other ESCOs or that other state regulatory agencies to which we are subject will not continue trying to implement restrictive anti-competitive regulations on us and other ESCOs.

Recently, certain state commissions have begun efforts to restrict the ability of retail suppliers to "pass through" costs to customers associated with certain changes in law or regulatory requirements. For example, on January 22, 2019, the New Jersey Board of Public Utilities ("NJ BPU") sent a cease and desist letter to third party suppliers ("TPS") in New Jersey instructing that a TPS may not charge a customer rate that is higher than the fixed rate applicable during the period for which that rate was fixed. The letter notified TPS that such increases were prohibited and instructed TPS to refund customers amounts charged in excess of the applicable fixed rate. Parties have challenged the NJ BPU's letter and it is not clear at this time whether refunds will be required. Similarly, the Connecticut Public Utilities Regulatory Authority ("PURA") recently opened a docket after receiving complaints regarding increases by suppliers to certain fixed-price supplier contracts due to change in law triggers. PURA will consider whether suppliers' actions constitute unfair and deceptive trade practices or otherwise violate applicable laws. PURA is expected to issue a declaratory ruling following its review. Depending on the outcome of these efforts in New Jersey and Connecticut, the Company may be required to assume costs that it otherwise would pass on to customers under its change in law provisions and potentially provide refunds to certain customers.

The retail energy business is subject to a high level of federal, state and local regulations, which are subject to change.
Our costs of doing business may fluctuate based on changing state, federal and local rules and regulations. For example, many electricity markets have rate caps, and changes to these rate caps by regulators can impact future price exposure. Similarly, regulatory changes can result in new fees or charges that may not have been anticipated when existing retail contracts were drafted, which can create financial exposure. Our ability to manage cost increases that result from regulatory changes will depend, in part, on how the "change in law provisions" of our contracts are interpreted and enforced, among other factors.Accordingly, changing or additional regulations or restrictions could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.

Liability under the TCPA has increased significantly in recent years, and we face risks if we fail to comply.

Our outbound telemarketing efforts and use of mobile messaging to communicate with our customers subjects us to regulation under the TCPA. Over the last several years, companies have been subject to significant liabilities as a result of violations of the TCPA, including penalties, fines and damages under class action lawsuits. In addition, the increased use by us and other consumer retailers of mobile messaging to communicate with our customers has created new issues of application of the TCPA to these communications. In 2015, the Federal Communications Commission issued several rulings that made compliance with the TCPA more difficult and costly. Our failure to effectively monitor and comply with our activities that are subject to the TCPA could result in significant penalties and the adverse effects of having to defend and ultimately suffer liability in a class action lawsuit related to such non-compliance.

Table of Contents


We are also subject to liability under the TCPA for actions of our third party vendors who are engaging in outbound telemarketing efforts on our behalf. The issue of vicarious liability for the actions of third parties in violation of the TCPA remains unclear and has been the subject of conflicting precedent in the federal appellate courts. There can be no assurance that we may be subject to significant damages as a result of a class action lawsuit for actions of our vendors that we may not be able to control.If any violation of the TCPA were to occur, it could materially and adversely affect our business, financial condition, cash flows, results of operations and, ability to pay dividends to the holders of our Class A common stock and Series a Preferred Stock.
We are, and in the future may become, involved in legal and regulatory proceedings and, as a result, may incur substantial costs.
We are subject to risks of significant liability resulting from class action lawsuits,

We are subject to lawsuits, claims and regulatory proceeds arising in the ordinary course of our business from time to time, including several purported
In recent years, retail energy providers have been named as defendants in class action lawsuits relating to pricing and sales practices, among other matters. A number of these lawsuits have resulted in substantial jury awards or settlements. We are currently a defendant in several class action lawsuits involving sales practices or TCPA claims and breach of contract claims. These are in various stages and are subject to substantial uncertainties concerning the outcome.
A negative outcome for any of these matters could result in significant damages. depending on whether a class is certified, and if so, the size of a such class. Future Litigation relating to our pricing and sales practices may Litigation may also negatively impact us by requiring us to pay substantial awards or settlements, increasing our legal costs, diverting management attention from other business issues or harming our reputation with customers.which could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
For additional information regarding the nature and status of certain proceedings, see Note 14 "Commitment and Contingencies" to the audited consolidated financial statements.
Our business is dependent on retaining licenses in the markets in which we operate.
Our business model is dependent on continuing to be licensed in existing markets. We may have a license revoked or not be granted a renewal of a license, or if our license could be adversely conditioned or modified (e.g., by increased bond posting obligations).it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.

We may be subject to risks in connection with acquisitions, which could cause us to fail to realize many of the anticipated benefits of such acquisitions.

We have grown our business in part through strategic acquisition opportunities from third parties and potentially from affiliates of our majority shareholder and may continue to do so in the future. Achieving the anticipated benefits of these transactions depends in part upon our ability to identify accretive acquisition targets, accurately assess the benefits

When we identify an acquisition candidate, there is a risk that we may be unable to negotiate terms that are beneficial to us. Additionally, even if we identify an accretive acquisition target, the successful acquisition of that business requires estimating anticipated cash flow and accretive value, evaluating potential regulatory challenges, retaining customers and assuming regulatory challenges, our ability to retain customers and assumed liabilities. The accuracy of these assessments is inherently uncertain and our assessments may turn out incorrect.estimates is inherently uncertain and our assumptions may turn out to be incorrect.

Furthermore, when we make an acquisition, we may not be able to accomplish the integration process smoothly or successfully. The difficulties of integrating our acquisitions potentially will include, among other things:acquisitions can include, among other things:

| | |
| - | coordinating geographically separate organizations and addressing possible differences in corporate cultures and management philosophies; |
| | |
| - | dedicating significant management resources to the integration of the acquisition, which may temporarily distract management's attention from the day-to-day business of the combined company; |
| | |
| - | increased liquidity needs to support working capital for the purchase of natural gas and electricity supply to meet our customers' needs, for the credit requirements of forward physical supply and for generally higher operating expenses; |
| | |
| - | operating in states and markets where we have not previously conducted business; |

| | |
| - | ensuring our hedging strategy adequately covers a customer base that is managed through multiple systems; and |
| | |
| - | successfully recognizing expected cost savings and other synergies in overlapping functions. |
In many of our acquisition agreements, we are entitled to indemnification from the counterparty for various matters, including breaches of representations, warranties and covenants, tax matters, and litigation proceedings. We generally obtain security to provide assurances that the counterparty could perform its indemnification obligations, which may be in the form of escrow accounts, payment withholding or other methods. However, to the extent that we do not obtain security, or the security turns out to be inadequate, there is a risk that the counterparty may fail to perform on its indemnification obligations, which could result in the losses being incurred by us.

Our ability to grow at levels experienced historically may be constrained if the market for acquisition candidates is limited and we are unable to make acquisitions of portfolios of customers and retail energy companies on commercially reasonable terms.
if any of the risks above were to occur, it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
Pursuant to our cash dividend policy, we distribute a significant portion of our cash through regular quarterly dividends, and our ability to grow and make acquisitions with cash on hand could be limited.
Pursuant to our cash dividend policy, we have been distributing, and intend to distribute, a significant portion of our cash through regular quarterly dividends to holders of our Class A common stock and dividends on our Series A Preferred Stock. As such, our growth may not be as fast as that of businesses that reinvest their available cash to expand ongoing operations, and we may have to rely upon external financing sources, including the issuance of debt, equity securities, convertible subordinated notes and borrowings under our Senior Credit Facility and Subordinated Facility. If These sources may not be available, and our ability to grow and maintain our business may be limited.which could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.

We may not be able to manage our growth successfully.
The growth of our operations will depend upon our ability to expand our customer base in our existing markets and to enter new markets in a timely manner at reasonable costs, organically or through acquisitions. In order for us to recover expenses incurred in entering new markets and obtaining new customers, we must attract and retain customers on economic terms and for extended periods. We may experience difficulty managing our growth and

implementing new product offerings, integrating new customers and employees, and complying with applicable market rules and the infrastructure for product delivery.

Expanding our operations also may require continued development of our operating and financial controls and may place additional stress on our management and operational resources. We may be unable to manage our growth and development successfully.it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.

The termination of our Master Service Agreement subjects us to a variety of risks.

A significant portion of our operations, including enrollment and renewal transaction services, customer billing and transaction services, electronic payment processing services, customer services and information technology infrastructure and application support services, is currently provided to us by our affiliate, Retailco Services, LLC, for a fixed fee under the Master Service Agreement. The Master Service Agreement will terminate effective April 1, 2018, and we will be reintegrating the services previously provided to us by Retailco Services, LLC under the Master Service Agreement back into our operations. We may experience costs integrating these services back into our operations. Additionally, following the integration of those services back into our operations, we may

Table of Contents

experience fluctuations in general and administrative costs that we did not experience under the fixed-fee arrangement of the Master Service Agreement. If any of the risks above were to occur, it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.

Our financial results fluctuate on a seasonal, quarterly and annual basis.
Our overall operating results fluctuate substantially on a seasonal, quarterly and annual basis depending on: (1) the geographic mix of our customer base; (2) the concentration of our product mix; (3) the impact of weather conditions on commodity pricing and demand; (4) variability in market prices for natural gas and electricity, and (5) changes in the cost of delivery of commodities through energy delivery networks. These factors can have material short-term impacts on monthly and quarterly operating results, which may be misleading when considered outside of the context of our annual operating cycle. In addition, our accounts payable and accounts receivable are impacted by seasonality due to the timing differences between when we pay our suppliers for accounts payable versus when we collect from our customers on accounts receivable. We typically pay our suppliers for purchases of natural gas on a monthly basis and electricity on a weekly basis. However, it takes approximately two months from the time we deliver the electricity or natural gas to our customers before we collect from our customers on accounts receivable attributable to those supplies. This timing difference could affect our cash flows, especially during peak cycles in the winter and summer months. Furthermore, as a result of the seasonality of our business, we may reserve a portion of our excess cash available for distribution in the first and fourth quarters in order to fund our second and third quarter distributions.
Additionally, we enter into a variety of financial derivative and physical contracts to manage commodity price risk, and we use mark-to-market accounting to account for this hedging activity. Under the mark-to-market accounting method, changes in the fair value of our hedging instruments that are not qualifying or not designated as hedges under accounting rules are recognized immediately in earnings. As a result of this accounting treatment, changes in the forward prices of natural gas and electricity cause volatility in our quarterly and annual earnings, which we are unable to fully anticipate.
We could also incur volatility from quarter to quarter associated with gains and losses on settled hedges relating to natural gas held in inventory if we choose to hedge the summer-winter spread on our retail allocated storage capacity. We typically purchase natural gas inventory and store it from April to October for withdrawal from November through March. Since a portion of the inventory is used to satisfy delivery obligations to our fixed-price customers over the winter months, we hedge the associated price risk using derivative contracts. Any gains or losses associated with settled derivative contracts are reflected in the statement of operations as a component of retail cost of sales and net asset optimization.
Accordingly, we may experience seasonal, quarterly and annual fluctuations, which could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
We may have difficulty retaining our existing customers or obtaining a sufficient number of new customers, due to competition and for other reasons.
The markets in which we compete are highly competitive, and we may face difficulty retaining our existing customers or obtaining new customers due to competition. We encounter significant competition from local regulated utilities or their retail affiliates and traditional and new retail energy providers. Many of these competitors or potential competitors are larger than us, have access to more significant capital resources, have more well-established brand names and have larger existing installed customer bases.
Additionally, existing customers may switch to other retail energy service providers during their contract terms in the event of a significant decrease in the retail price of natural gas or electricity in order to obtain more favorable prices. Although we generally have a right to collect a termination fee from each customer on a fixed-price contract

who terminates their contract early, we may not be able to collect the termination fees in full or at all. Our variable-price contracts can typically be terminated by our customers at any time without penalty.

Increased collateral requirements in connection with our supply activities may restrict our liquidity.which could limit our ability to grow our business or pay dividends.
Our contractual agreements with certain local regulated utilities and our supplier counterparties require us to maintain restricted cash balances or letters of credit as collateral for credit risk or the performance risk associated with the future delivery of natural gas or electricity. These collateral requirements may increase as we grow our customer base. Collateral requirements will increase based on the volume or cost of the commodity we purchase in any given month and the amount of capacity or service contracted for with the local regulated utility. Significant changes in market prices also can result in fluctuations in the collateral that local regulated utilities or suppliers require.
The effectiveness of our operations and future growth depend in part on the amount of cash and letters of credit available to enter into or maintain these contracts. The cost of these arrangements may be affected by changes in credit markets, such as interest rate spreads in the cost of financing between different levels of credit ratings. These liquidity requirements may be greater than we anticipate or are able to meet.If any of these risks were to occur, it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
We are subject to direct credit risk for certain customers who may fail to pay their bills as they become due.
We bear direct credit risk related to our customers located in markets that have not implemented POR programs as well as indirect credit risk in those POR markets that pass collection efforts along to us after a specified non-payment period. For the year ended December 31, 2018 , customers in non-POR markets represented approximately 34% of our retail revenues. We generally have the ability to terminate contracts with customers in the event of non-payment, but in most states in which we operate we cannot disconnect their natural gas or electricity service. In POR markets where the local regulated utility has the ability to return non-paying customers to us after specified periods, we may realize a loss for one to two billing periods until we can terminate these customers' contracts. We may also realize a loss on fixed-price customers in this scenario due to the fact that we will have already fully hedged the customer's expected commodity usage for the life of the contract and we also remain liable to our suppliers of natural gas and electricity for the cost of our supply commodities. Furthermore, in the Texas market, we are responsible for billing the distribution charges for the local regulated utility and are at risk for these charges, in addition to the cost of the commodity, in the event customers fail to pay their bills. Changing economic factors, such as rising unemployment rates and energy prices also result in a higher risk of customers being unable to pay their bills when due.
The failure of our customers to pay their bills or our failure to maintain adequate billing and collection procedures could adversely affect our financial results and our ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
Our indebtedness could adversely affect our ability to raise additional capital to fund our operations or pay dividends. It could also expose us to the risk of increased interest rates and limit our ability to react to changes in the economy or our industry as well as impact our cash available for distribution.

Table of Contents

We have $129.5 million of indebtedness outstanding and $49.4 million in issued letters of credit under our Senior Credit Facility, and $10.0 million of indebtedness outstanding under our Subordinated Facility as of December 31, 2018 . Debt we incur under our Senior Credit Facility, Subordinated Facility or otherwise could have negative consequences, including:
| | |
| - | increasing our vulnerability to general economic and industry conditions; |
| | |
| - | requiring cash flow from operations to be dedicated to the payment of principal and interest on our indebtedness, therefore reducing or eliminating our ability to pay dividends to holders of our Class A common stock and Series A Preferred Stock, or to use our cash flow to fund our operations, capital expenditures and future business opportunities; |
| | |
| - | limiting our ability to fund future acquisitions or engage in other activities that we view as in our long-term best interest; |
| | |
| - | restricting our ability to make certain distributions with respect to our capital stock and the ability of our subsidiaries to make certain distributions to us, in light of restricted payment and other financial covenants, including requirements to maintain certain financial ratios, in our credit facilities and other financing agreements; |

25

Table of Contents

| | |
| - | exposing us to the risk of increased interest rates because certain of our borrowings borrowings under our Senior Credit Facility are at variable rates of interest; and |
| | |
| - | limiting our ability to obtain additional financing for working capital including collateral postings, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes. |
If we are unable to satisfy financial covenants in our debt instruments, it could result in an event of default that, if not cured or waived, may entitle the lenders to demand repayment or enforce their security interests. Our Senior Credit Facility will mature in May 2020, and we cannot assure that we will be able to negotiate a new credit arrangement on commercially reasonable terms.The occurrence of any of the events above could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
We depend on the accuracy of data in our information management systems, which subjects us to risks.
We depend on the accuracy and timeliness of our information management systems for billing, collections, consumption and other important data. We rely on many internal and external sources for this information, including:
| | |
| - | our marketing, pricing and customer operations functions; and |
| | |
| - | various local regulated utilities and ISOs for volume or meter read information, certain billing rates and billing types (e.g., budget billing) and other fees and expenses. |
Inaccurate or untimely information, which may be outside of our direct control, could result in:
| | |
| - | inaccurate and/or untimely bills sent to customers; |
| | |
| - | incorrect tax remittances; |
| | |
| - | reduced effectiveness and efficiency of our operations; |
| | |
| - | inability to adequately hedge our portfolio; |
| | |
| - | increased overhead costs; |
| | |
| - | inaccurate accounting and reporting of customer revenues, gross margin and accounts receivable activity; |
| | |
| - | inaccurate measurement of usage rates, throughput and imbalances; |
| | |
| - | customer complaints; and |
| | |
| - | increased regulatory scrutiny. |
We are also subject to disruptions in our information management systems arising out of events beyond our control, such as natural disasters, epidemics, failures in hardware or software, power fluctuations, telecommunications and

29

Table of Contents

other similar disruptions. In addition, our information management systems may be vulnerable to computer viruses, incursions by intruders or hackers and cyber terrorists and other similar disruptions. A successful cyber-attack on our information management systems could severely disrupt business operations, preventing us from billing and collecting revenues, and could result in significant expenses to investigate and repair security breaches or system damage, lead to litigation, fines, other remedial action, heightened regulatory scrutiny, diminished customer confidence and damage to our reputation. Although we maintain cyber-liability insurance that covers certain damage caused by cyber events,
Inaccurate data and disruptions of our information management systems to perform as anticipated for any reason could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
it may not be sufficient to cover us in all circumstances.
Our success depends on key members of our management, the loss of whom could disrupt our business operations.
We depend on the continued employment and performance of key management personnel. A number of our senior executives have substantial experience in consumer and energy markets that have undergone regulatory restructuring and have extensive risk management and hedging expertise. We believe their experience is important to our continued success. We do not maintain key life insurance policies for our executive officers. If Our key executives may not continue in their present roles and are not adequately replaced.it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.may not be adequately replaced.

We rely on a third party vendor for our customer billing and transactions platform that exposes us to third party performance risk.
We have outsourced our back office customer billing and transactions functions to a third party, and we rely heavily on the continued performance of that vendor under the outsourcing agreement. Our vendor may fail to operate in accordance with the terms of the outsourcing agreement or a bankruptcy or other event may prevent it from performing under our outsourcing agreement.could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
A large portion of our current customers are concentrated in a limited number of states, making us vulnerable to customer concentration risks.
As of December 31, 2018 , approximately 62% of our RCEs were located in five states. Specifically, 16% , 14% , 12% , 11% and 9% of our customers on an RCE basis were located in NY, MA, PA, CT and ME, respectively. If we are unable to increase our market share across other competitive markets or enter into new competitive markets effectively, we may be subject to continued or greater customer concentration risk. In addition, if any of The states that contain a large percentage of our customers could reverse regulatory restructuring or change the regulatory environment in a manner that causes us to be unable to economically operate in that state.it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
Increases in state renewable portfolio standards or an increase in the cost of renewable energy credit and carbon offsets may adversely impact the price, availability and marketability of our products.
Pursuant to state renewable portfolio standards, we must purchase a specified amount of renewable energy credits, or RECs based on the amount of electricity we sell in a state in a year. In addition, we have contracts with certain customers that require us to purchase RECs or carbon offsets. If a state increases its renewable portfolio standards, the demand for RECs within that state will increase and therefore the market price for RECs could increase. We attempt to forecast the price for the required RECs and carbon offsets at the end of each month and incorporate this forecast into our customer pricing models, but the price paid for RECs and carbon offsets may be higher than

30

Table of Contents

forecasted. We may be unable to fully pass the higher cost of RECs through to our customers, and increases in the price of RECs may decrease our results of operations and affect our ability to compete with other energy retailers that have not contracted with customers to purchase RECs or carbon offsets. Further, a price increase for RECs or carbon offsets may require us to decrease the renewable portion of our energy products, which may result in a loss of customers. A further reduction in benefits received by local regulated utilities from production tax credits in respect of renewable energy may adversely impact the availability to us, and marketability by us, of renewable energy under our brands.Accordingly, such decrease may result in reduced revenue and could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
Our access to marketing channels may be contingent upon the viability of our telemarketing and door-to-door agreements with our vendors.
Our vendors are essential to our telemarketing and door-to-door sales activities. Our ability to increase revenues in the future will depend significantly on our access to high quality vendors. If we are unable to attract new vendors and retain existing vendors to achieve our marketing targets, our growth may be materially reduced. There can be no assurance that competitive conditions will allow these vendors and their independent contractors to continue to successfully sign up new customers. Further, if our products are not attractive to, or do not generate sufficient revenue for our vendors, we may lose our existing relationships. In addition, the decline in landlines reduces the number of potential customers that may be reached by our telemarketing efforts and as a result our telemarketing sales channel may become less viable and we may be required to use more door-to-door marketing. Door-to-door marketing is continually under scrutiny by state regulators and legislators, which may lead to new rules and regulations that impact our ability to use these channels.If any of these risks were to occur, it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
Our vendors may expose us to risks.
We are subject to reputational risks that may arise from the actions of our vendors and their independent contractors that are wholly or partially beyond our control, such as violations of our marketing policies and procedures as well as any failure to comply with applicable laws and regulations. If our vendors engage in marketing practices that are

27

Table of Contents

not in compliance with local laws and regulations, we may be in breach of applicable laws and regulations that may result in regulatory proceedings, disadvantageous conditioning of our energy retailer license, or the revocation of our energy retailer license. Unauthorized activities in connection with sales efforts by agents of our vendors, including calling consumers in violation of the TCPA and predatory door-to-door sales tactics and fraudulent misrepresentation could subject us to class action lawsuits against which we will be required to defend. Such defense efforts will be costly and time consuming. In addition, the independent contractors of our vendors may consider us to be their employer and seek compensation.
If any of these risks were to occur, it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
Risks Related to Our Capital Stock
We cannot assure you that we will be able to continue paying our targeted quarterly dividend to the holders of our Class A common stock or dividends to the holders of our Series A Preferred Stock in the future.
The amount of our cash available for distribution principally depends upon the amount of cash we generate from our operations, which fluctuates from quarter to quarter based on, among other things:
| | |
| - | changes in commodity prices, which may be driven by a variety of factors, including, but not limited to, weather conditions, seasonality and demand for energy commodities and general economic conditions; |
| | |
| - | the level and timing of customer acquisition costs we incur; |
31

Table of Contents

| | |
| - | the level of our operating and general and administrative expenses; |
| | |
| - | seasonal variations in revenues generated by our business; |
| | |
| - | our debt service requirements and other liabilities; |
| | |
| - | fluctuations in our working capital needs; |
| | |
| - | our ability to borrow funds and access capital markets; |
| | |
| - | restrictions contained in our debt agreements (including our Senior Credit Facility); |
- management of customer credit risk;
| | |
| - | abrupt changes in regulatory policies; and, |
| | |
| - | other business risks affecting our cash flows. |
As a result of these and other factors, we cannot guarantee that we will have sufficient cash generated from operations to pay the dividends on our Series A Preferred Stock or to pay a specific level of cash dividends to holders of our Class A common stock.
Due to the seasonality of our retail natural gas business, we generate the substantial majority of our cash available for distribution in the first and fourth quarters of each year. As a result of seasonality and our customer acquisition costs, we may not have sufficient cash available for distribution to cover quarterly dividends for certain quarters.
The amount of cash available for distribution depends primarily on our cash flow, and is not solely a function of profitability, which is affected by non-cash items. We may incur other expenses or liabilities during a period that could significantly reduce or eliminate our cash available for distribution and, in turn, impair our ability to pay dividends to holders of our Class A common stock and Series A Preferred Stock during the period. Additionally, the dividends paid on Series A Preferred Stock reduce the amount of cash we have available to pay dividends on our Class A common stock.
Each new share of Class A common stock and Series A Preferred Stock issued increases the cash required to continue to pay cash dividends. Any Class A common stock or preferred stock (whether Series A Preferred Stock or a new series of preferred stock) that may in the future be issued to finance acquisitions, upon exercise of stock options or otherwise, would have a similar effect.
Finally, dividends to holders of our Class A common stock are paid at the discretion of our board of directors. Our board of directors may decrease the level of or entirely discontinue payment of dividends.
We could be prevented from paying cash dividends on the Class A common stock and Series A Preferred Stock.
Holders of shares of Class A common stock and Series A Preferred Stock do not have a right to dividends on such shares unless declared or set aside for payment by our board of directors. Under Delaware law, cash dividends on capital stock may only be paid from "surplus" or, if there is no "surplus," from the corporation's net profits for the

28

Table of Contents

then-current or the preceding fiscal year. Unless we operate profitably, our ability to pay cash dividends on the Class A common stock and Series A Preferred Stock would require the availability of adequate "surplus," which is defined as the excess, if any, of net assets (total assets less total liabilities) over capital. Our business may not generate sufficient cash flow from operations to enable us to pay dividends on the Series A Preferred Stock when payable, and quarterly dividends on the Class A common stock. Further, even if adequate surplus is available to pay cash dividends on the Class A common stock and Series A Preferred Stock, we may not have sufficient cash to pay dividends on the Class A common stock or Series A Preferred Stock.
Furthermore, no dividends on Class A common stock or Series A Preferred Stock shall be authorized by our board of directors or paid, declared or set aside for payment by us at any time when the authorization, payment, declaration or setting aside for payment would be unlawful under Delaware law or any other applicable law, or when the terms and provisions of any documents limiting the payment of dividends prohibit the authorization, payment, declaration or setting aside for payment thereof or would constitute a breach or a default under such document.

Table of Contents

We are a holding company. Our sole material asset is our equity interest in Spark HoldCo, LLC ("Spark HoldCo") and we are accordingly dependent upon distributions from Spark HoldCo to pay dividends on the Class A common stock and Series A Preferred Stock.
We are a holding company and have no material assets other than our equity interest in Spark HoldCo, and have no independent means of generating revenue. To the extent that we need funds and Spark HoldCo or its subsidiaries may be restricted from making distributions to us under applicable law or regulation or under the terms of their financing arrangements, or may otherwise be unable to provide such funds.it could materially and adversely affect our business, financial condition, cash flows, results of operations and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock.
The Class A common stock and Series A Preferred Stock are subordinated to our existing and future debt obligations.
The Class A common stock and Series A Preferred Stock are subordinated to all of our existing and future indebtedness (including indebtedness outstanding under the Senior Credit Facility). Therefore, if we become bankrupt, liquidate our assets, reorganize or enter into certain other transactions, assets will be available to pay our obligations with respect to the Series A Preferred Stock only after we have paid all of our existing and future indebtedness in full. The Class A common stock will only receive assets to the extent all existing and future indebtedness and obligations under the Series A Preferred Stock is paid in full. If any of these events were to occur, there may be insufficient assets remaining to make any payments to holders of the Series A Preferred Stock or Class A common stock.
Additionally, none of our subsidiaries has guaranteed or otherwise become obligated with respect to the Class A common stock or Series A Preferred Stock. As a result, the Class A common stock and Series A Preferred Stock effectively rank junior to all existing and future indebtedness and other liabilities of our subsidiaries, including our operating subsidiaries, and any capital stock of our subsidiaries not held by us. Accordingly, our right to receive assets from any of our subsidiaries upon our bankruptcy, liquidation or reorganization, and the right of holders of shares of Class A common stock and Series A Preferred Stock to participate in those assets, is also structurally subordinated to claims of that subsidiary's creditors, including trade creditors. Even if we were a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of that subsidiary and any indebtedness of that subsidiary senior to that held by us.
Numerous factors may affect the trading price of the Class A common stock and Series A Preferred Stock.
The trading price of the Class A common stock and Series A Preferred Stock may depend on many factors, some of which are beyond our control, including:

| | |
| - | prevailing interest rates; |
| | |
| - | the market for similar securities; |

29

Table of Contents

- general economic and financial market conditions;
- our issuance of debt or other preferred equity securities; and
| | |
| - | our financial condition, results of operations and prospects. |
One of the factors that will influence the price of the Class A common stock and Series A Preferred Stock will be the distribution yield of the securities (as a percentage of the then market price of the securities) relative to market interest rates. Increases in market interest rates, which have been at low levels relative to historical rates, may lead prospective purchasers of shares of Class A common stock or Series A Preferred Stock to expect a higher distribution yield, and cause them to sell their Class A common stock or Series A Preferred Stock. Accordingly, higher market interest rates could cause the market price of the Class A common stock and Series A Preferred Stock to decrease.
33

Table of Contents

In addition, over the last several years, prices of equity securities in the U.S. trading markets have been experiencing extreme price fluctuations. As a result of these and other factors, investors holding our Class A common stock and Series A Preferred Stock may experience a decrease in the value of their securities, which could be substantial and rapid, and could be unrelated to our financial condition, performance or prospects.
There may not be an active trading market for the Class A common stock or Series A Preferred Stock, which may in turn reduce the market value and your ability to transfer or sell your shares of Class A common stock or Series A Preferred Stock.
There are no assurances that there will be an active trading market for our Class A common stock or Series A Preferred Stock. The liquidity of any market for the Class A common stock and Series A Preferred Stock depends upon the number of stockholders, our results of operations and financial condition, the market for similar securities, the interest of securities dealers in making a market in the Class A common stock and Series A Preferred Stock, and other factors. To the extent that an active trading market is not maintained, the liquidity and trading prices for the Class A common stock and Series A Preferred Stock may be harmed.
Furthermore, because the Series A Preferred Stock does not have any stated maturity and is not subject to any sinking fund or mandatory redemption, stockholders seeking liquidity will be limited to selling their respective shares of Series A Preferred Stock in the secondary market. Active trading markets for the Series A Preferred Stock may not exist at such times, in which case the trading price of your shares of our Series A Preferred Stock could be reduced and your ability to transfer such shares could be limited.
Our Founder holds a substantial majority of the voting power of our common stock.
Holders of Class A common stock and Class B common stock vote together as a single class on all matters presented to our stockholders for their vote or approval, except as otherwise required by applicable law or our certificate of incorporation and bylaws. Our Founder controls 66.1% of the combined voting power of the Class A common stock and Class B common stock as of December 31, 2018 through his direct and indirect ownership including Retailco, LLC, which is the holder of approximately 63.3% of the combined voting power of the Class A common stock and Class B common stock.in us.
Retailco, LLC is entitled to act separately in its own interest Affiliated owners are entitled to act separately with respect to their investment in us, and they have the ability to elect all of the members of our board of directors, and thereby to control our management and affairs. In addition, affiliates are able to determine the outcome of all matters requiring Class A common stock and Class B common stock shareholder approval, including mergers and other material transactions, and is able to cause or prevent a change in the composition of our board of directors or a change in control of our company that could deprive our stockholders of an opportunity to receive a premium for their Class A common stock as part of a sale of our company. The existence of a significant shareholder, such as our Founder, may also have the effect of deterring hostile takeovers, delaying or preventing changes in control or changes in management, or limiting the ability of our other stockholders to approve transactions that they may deem to be in the best interests of our company.
So long as affiliates continue to control a significant amount of our common stock, they will continue to be able to strongly influence all matters requiring shareholder approval, regardless of whether other stockholders believe that a potential transaction is in their own best interests. In any of these matters, the interests of affiliates may differ or

30

Table of Contents

conflict with the interests of our other stockholders. Moreover, this concentration of stock ownership may also adversely affect the trading price of our Class A common stock or Series A Preferred Stock to the extent investors perceive a disadvantage in owning stock of a company with a controlling shareholder.
Holders of Series A Preferred Stock you have extremely limited voting rights.
Your Voting rights of holders of shares of Series A Preferred Stock are extremely limited. Our Class A common stock and our Class B common stock are the only classes of our securities carrying full voting rights. Holders of the Series A Preferred Stock generally have no voting rights.

We are a "controlled company" under NASDAQ Global Select Market rules, and as such we are entitled to an exemption from certain corporate governance standards of the NASDAQ Global Select Market, and you may not have the same protections afforded to shareholders of companies that are subject to all of the NASDAQ Global Market corporate governance requirements.
We qualify as a "controlled company" within the meaning of NASDAQ Global Select Market corporate governance standards because an affiliated holder controls more than 50% of our voting power. Under NASDAQ Global Select Market rules, a company of which more than 50% of the voting power is held by an individual, a group or another company is a "controlled company" and may elect not to comply with certain corporate governance requirements.
In light of our status as a controlled company, our board of directors has determined to take partial advantage of the controlled company exemption. Our board of directors has determined not to have a nominating and corporate governance committee and that our compensation committee will not consist entirely of independent directors. As a result, non-independent directors may among other things, appoint future members of our board of directors, resolve corporate governance issues, establish salaries, incentives and other forms of compensation for officers and other employees and administer our incentive compensation and benefit plans.
Accordingly, you may not have the same protections afforded to shareholders of companies that are subject to all of NASDAQ Global Select Market corporate governance requirements.
We engage in transactions with our affiliates and expect to do so in the future. The terms of such transactions and the resolution of any conflicts that may arise may not always be in our or our stockholders' best interests.
We have engaged in transactions and expect to continue to engage in transactions with affiliated companies. We have acquired companies and books of customers from our affiliates and may do so in the future. We will continue to enter into back-to-back transactions for purchases of commodities and derivatives on behalf of our affiliate. We will also continue to pay certain expenses on behalf of several of our affiliates for which we will seek reimbursement. We will also continue to share our corporate headquarters with certain affiliates. We cannot assure that our affiliates will reimburse us for the costs we have incurred on their behalf or perform their obligations under any of these contracts.
Our amended and restated certificate of incorporation and amended and restated bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids or merger proposals, which may adversely affect the market price of our Class A common stock.
Our amended and restated certificate of incorporation authorizes our board of directors to issue preferred stock without shareholder approval. On October 7, 2016, we filed a registration statement under the Securities Act on Form S-3 allowing us to offer and sell, from time to time, shares of preferred stock. The registration statement was declared effective on October 20, 2016. The election by our board of directors to issue preferred stock with anti-takeover provisions could make it more difficult for a third party to acquire us.
In addition, some provisions of our amended and restated certificate of incorporation and amended and restated bylaws could make it more difficult for a third party to acquire control of us, even if the change of control would be

31

Table of Contents

beneficial to our stockholders. Among other things, our amended and restated certificate of incorporation and amended and restated bylaws:
| | |
| - | provide for our board of directors to be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three year terms. Our staggered board may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for shareholders to replace a majority of the directors; |
| | |
| - | provide that the authorized number of directors may be changed only by resolution of the board of directors; |
35

Table of Contents

| | |
| - | provide that all vacancies in our board, including newly created directorships, may, except as otherwise required by law or, if applicable, the rights of holders of a series of preferred stock, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum; |
| | |
| - | provide our board of directors the ability to authorize undesignated preferred stock. This ability makes it possible for our board of directors to issue, without shareholder approval, preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company; |
| | |
| - | provide that at any time after the first date upon which W. Keith Maxwell III no longer beneficially owns more than fifty percent of the outstanding Class A common stock and Class B common stock, any action required or permitted to be taken by the shareholders must be effected at a duly called annual or special meeting of shareholders and may not be effected by any consent in writing in lieu of a meeting of such shareholders, subject to the rights of the holders of any series of preferred stock with respect to such series (prior to such time, such actions may be taken without a meeting by written consent of holders of the outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting); |
| | |
| - | provide that at any time after the first date upon which W. Keith Maxwell III no longer beneficially owns more than fifty percent of the outstanding Class A common stock and Class B common stock, special meetings of our shareholders may only be called by the board of directors, the chief executive officer or the chairman of the board (prior to such time, special meetings may also be called by our Secretary at the request of holders of record of fifty percent of the outstanding Class A common stock and Class B common stock); |
| | |
| - | provide that our amended and restated certificate of incorporation and amended and restated bylaws may be amended by the affirmative vote of the holders of at least two-thirds of our outstanding stock entitled to vote thereon; |
| | |
| - | provide that our amended and restated bylaws can be amended by the board of directors; and |
| | |
| - | establish advance notice procedures with regard to shareholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our shareholders. These procedures provide that notice of shareholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. These requirements may preclude shareholders from bringing matters before the shareholders at an annual or special meeting. |
In addition, in our amended and restated certificate of incorporation, we have elected not to be subject to the provisions of Section 203 of the Delaware General Corporation Law (the "DGCL") regulating corporate takeovers until the date on which W. Keith Maxwell III no longer beneficially owns in the aggregate more than fifteen percent of the outstanding Class A common stock and Class B common stock. On and after such date, we will be subject to the provisions of Section 203 of the DGCL.
In addition, certain change of control events have the effect of accelerating the payment due under our Tax Receivable Agreement, which could be substantial and accordingly serve as a disincentive to a potential acquirer of our company.
Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our

32

Table of Contents

stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.
Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim against us or any director or officer or other employee of ours arising pursuant to any provision of the DGCL, our amended and restated certificate of

36

Table of Contents

incorporation or our bylaws, or (iv) any action asserting a claim against us or any director or officer or other employee of ours that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and consented to, the provisions of our amended and restated certificate of incorporation described in the preceding sentence. This choice of forum provision may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.
Future sales of our Class A common stock and Series A Preferred Stock in the public market could reduce the price of the Class A common stock and Series A Preferred Stock, and may dilute your ownership in us.
On October 7, 2016, we filed a registration statement under the Securities Act on Form S-3 registering the primary offer and sale, from time to time, of Class A common stock, preferred stock, depositary shares and warrants. The registration statement also registers the Class A common stock held by our affiliates, Retailco and NuDevco (including Class A common stock that may be obtained upon conversion of Class B common stock). All of the shares of Class A common stock held by Retailco and NuDevco and registered on the registration statement may be immediately resold. The registration statement was declared effective on October 20, 2016.
We cannot predict the size of future issuances of our Class A common stock or securities convertible into Class A common stock or the effect, if any, that future issuances or sales of shares of our Class A common stock will have on the market price of our Class A common stock. Sales of substantial amounts of our Class A common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of our Class A common stock.
We may also in the future sell additional shares of preferred stock, including shares of Series A Preferred Stock, on terms that may differ from those we have previously issued. Such shares could rank on parity with or, subject to the voting rights referred to above (with respect to issuances of new series of preferred stock), senior to the Series A Preferred Stock as to distribution rights or rights upon liquidation, winding up or dissolution. The subsequent issuance of additional shares of Series A Preferred Stock, or the creation and subsequent issuance of additional classes of preferred stock on parity with the Series A Preferred Stock, could dilute the interests of the holders of Series A Preferred Stock, and could affect our ability to pay distributions on, redeem or pay the liquidation preference on the Series A Preferred Stock. Any issuance of preferred stock that is senior to the Series A Preferred Stock would not only dilute the interests of the holders of Series A Preferred Stock, but also could affect our ability to pay distributions on, redeem or pay the liquidation preference on the Series A Preferred Stock.
Furthermore, subject to compliance with the Securities Act or exemptions therefrom, employees who have received Class A common stock as equity awards may also sell their shares into the public market.
We will be required to make payments under a Tax Receivable Agreement with our Founder for certain tax benefits we may claim, and the amounts of such payments could be significant.

We are party to a Tax Receivable Agreement with Spark HoldCo, NuDevco Retail Holdings and NuDevco Retail. This Agreement"("Tax Receivable Agreement" or "TRA") that generally provides for the payment by us to Retailco, LLC (as successor to NuDevco Retail Holdings) and NuDevco Retail our Founder of 85% of the net cash savings, if any, in U.S. federal, state and local income tax or franchise tax that we actually realize (or are deemed to realize in certain circumstances) in future periods as a result of (i) any tax basis increase resulting from the purchase by us of SparkHoldCo units from NuDevco Retail Holdings, units of our subsidiary from affiliates of our Founder, (ii) any tax basis increases resulting from the exchange of these units for shares of Class A common stock pursuant to the Exchange Right (or resulting from an exchange of Spark HoldCo units for cash pursuant to a Cash Option) and (iii) any imputed interest deemed to be paid by us as a result of, and additional tax basis arising from, any payments we make under the Tax Receivable Agreement. In addition, payments we make

under the Tax Receivable Agreement will be increased by any interest accrued from the due date (without extensions) of the corresponding tax return. We retain the benefit of the remaining 15% of these tax savings. See Note 13 "Income Taxes" for further discussion.
We may be required to defer or partially defer any payment due to holders of rights under the Tax Receivable Agreement in certain circumstances during the five-year period commencing on October 1, 2014. Following the expiration of the five-year deferral period, we will be obligated to pay any outstanding deferred TRA Payments. While this payment obligation is subject to certain limitations, the obligation may nevertheless be significant and could adversely affect our liquidity and ability to pay dividends to the holders of our Class A common stock and Series A Preferred Stock. As of December 31, 2018 , we had no outstanding deferred TRA payments.
The payment obligations under the Tax Receivable Agreement are obligations of Spark Energy, Inc. and not obligations of Spark HoldCo. For purposes of the Tax Receivable Agreement, cash savings in tax generally are calculated by comparing our actual tax liability to the amount we would have been required to pay had we not been able to utilize any of the tax benefits subject to the Tax Receivable Agreement. The term of the Tax Receivable Agreement continues until all such tax benefits have been utilized or expired, unless we exercise our right to terminate the Tax Receivable Agreement by making the termination payment specified in the agreement.
The actual increase in tax basis, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including the timing of the exchanges of Spark HoldCo units, the price of Class A common stock at the time of each exchange, the extent to which such exchanges are taxable, the amount and timing of the taxable income we generate in the future and the tax rate then applicable, and the portion of our payments under the Tax Receivable Agreement constituting imputed interest or depletable, depreciable or amortizable basis. We expect that the payments that we will be required to make under the Tax Receivable Agreement could be substantial.
The payments under the Tax Receivable Agreement will not be conditioned upon a holder of rights under the Tax Receivable Agreement having a continued ownership interest in either Spark HoldCo or us.

We did not meet the threshold coverage ratio required to fund the first payment to NuDevco Retail Holdings under the Tax Receivable Agreement During the four-quarter period ending September 30, 2015. As such, the initial payment under the Tax Receivable Agreement due in late 2015 was deferred pursuant to the terms thereof.
During 2018, we made the payments required under the TRA for the 2015, 2016 and 2017 tax years. See Note 15 "Transactions with Affiliates" for a discussion of amounts paid and accrued under the TRA.

we met the threshold coverage ratio required to fund the second TRA Payment to Retailco and NuDevco Retail under the Tax Receivable Agreement during the four-quarter period ending September 30, 2016, resulting in an initial TRA Payment of $1.4 million becoming due in December 2016. On November 6, 2016, Retailco and NuDevco Retail granted us the right to defer the TRA Payment until May 2018. During the period of time when we have elected to defer the TRA Payment, the outstanding payment amount will accrue interest at a rate calculated in the manner provided for under the Tax Receivable Agreement.


We met the threshold coverage ratio required to fund the third TRA Payment to Retailco and NuDevco Retail under the Tax Receivable Agreement during the four-quarter period ended September 30, 2017 As such, the third payment under the tax Receivable Agreement due in April 2018 has been classified as current in our consolidated balance sheet at December 31, 2017.
We expect to meet the threshold coverage ratio required to fund the fourth payment to Retailco and NuDevco Retail under the Tax Receivable Agreement during the four-quarter period ending September 30, 2018. The fourth payment under the Tax Receivable Agreement would be due in late 2018.

In certain cases, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual benefits, if any, we realize in respect of the tax attributes subject to the Tax Receivable Agreement.
If we elect to terminate the Tax Receivable Agreement early or it is terminated early due to certain mergers or other changes of control, we would be required to make an immediate payment equal to the present value of the anticipated future tax benefits subject to the Tax Receivable Agreement, which calculation of anticipated future tax benefits will be based upon certain assumptions and deemed events set forth in the Tax Receivable Agreement, including the assumption that we have sufficient taxable income to fully utilize such benefits and that any Spark HoldCo units that Retailco, LLC, NuDevco Retail, or their permitted transferees own on the termination date are deemed to be exchanged on the termination date. Any early termination payment may be made significantly in advance of the actual realization, if any, of such future benefits.
In these situations, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms

of business combinations or other changes of control due to the additional transaction cost a potential acquirer may attribute to satisfying such obligations. For example, if the Tax Receivable Agreement had been terminated as of December 31, 2018 , the estimated contractual termination payment would be approximately $33.8 million (calculated using a discount rate equal to the one-year London Inter-Bank Offered Rate ("LIBOR"), plus 200 basis points). The foregoing number is merely an estimate and the actual payment could differ materially. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreement.
Payments under the Tax Receivable Agreement will be based on the tax reporting positions that we will determine. The holders of rights under the Tax Receivable Agreement will not reimburse us for any payments previously made under the Tax Receivable Agreement if such basis increases or other benefits are subsequently disallowed, except that excess payments made to any such holder will be netted against payments otherwise to be made, if any, to such holder after our determination of such excess. As a result, in such circumstances, we could make payments that are greater than our actual cash tax savings, if any, and may not be able to recoup those payments, which could adversely affect our liquidity.
We have issued preferred stock and may continue to do so, and the terms of such preferred stock could adversely affect the voting power or value of our Class A common stock.
Our certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our Class A common stock with respect to dividends and distributions, as our board of directors may determine. During the year ended December 31, 2017, we designated a class of preferred stock as Series A Preferred Stock and issued an aggregate of 94,339 Through December 31, 2018 , we have issued an aggregate of 3,707,256 shares of Series A Preferred Stock.
The terms of one or more classes or series of The terms of the preferred stock we offer or sell could adversely impact the voting power or value of our Class A common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock, such as the Series A Preferred Stock, could affect the residual value of the Class A common stock.
For as long as we are an emerging growth company, we will not be required to comply with certain reporting requirements, including those relating to accounting standards and disclosure about our executive compensation, that apply to other public companies.
In April 2012, the Jumpstart Our Business Startups Act (the "JOBS Act") was signed into law. We are classified as an "emerging growth company" under the JOBS Act. For as long as we are an emerging growth company, which may be up to five full fiscal years, unlike other public companies, we will not be required to, among other things, (i) provide an auditor's attestation report on management's assessment of the effectiveness of our system of internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act, (ii) comply with any new

39

Table of Contents

requirements adopted by the PCAOB requiring mandatory audit firm rotation or a supplement to the auditor's report in which the auditor would be required to provide additional information about the audit and the financial statements of the issuer, (iii) provide certain disclosure regarding executive compensation required of larger public companies or (iv) hold nonbinding advisory votes on executive compensation. We will remain an "emerging growth company" until as late as the last day of our 2019 fiscal year. or until the earliest of (i) the last day of the fiscal year in which we have $1.07 billion or more in annual revenues; (ii) the date on which we become a "large accelerated filer" (the fiscal year-end on which the total market value of our common equity securities held by non-affiliates is $700 million or more as of June 30); (iii) the date on which we issue more than $1.0 billion of non-convertible debt over a three -year period.After we cease to be an "emerging growth company," we may incur significant additional expense and devote substantial management effort toward ensuring compliance with the requirements applicable to companies that are not "emerging growth companies," including Section 404(b) of the Sarbanes-Oxley Act.
As a result of our election to avail ourselves of certain provisions of the JOBS Act, the information that we provide may be different than what you may receive from other public companies in which you hold an equity interest. To the extent that we rely on any of the exemptions available to emerging growth companies, you will receive less information about our executive compensation and internal control over financial reporting than issuers that are not emerging growth companies. If some investors find our securities to be less attractive as a result, there may be a less active trading market for our securities and the price may be more volatile.

Our amended and restated certificate of incorporation limits the fiduciary duties of one of our directors and certain of our affiliates and restricts the remedies available to our stockholders for actions taken by our Founder or certain of our affiliates that might otherwise constitute breaches of fiduciary duty.
Our amended and restated certificate of incorporation contains provisions that we renounce any interest in existing and future investments in other entities by, or the business opportunities of, NuDevco Partners, LLC, NuDevco Partners Holdings, LLC and W. Keith Maxwell III, or any of their officers, directors, agents, shareholders, members, affiliates and subsidiaries (other than a director or officer who is presented an opportunity solely in his capacity as a director or officer). Because of this provision, these persons and entities have no obligation to offer us those investments or opportunities that are offered to them in any capacity other than solely as an officer or director. If one of these persons or entities pursues a business opportunity instead of presenting the opportunity to us, we will not have any recourse against such person or entity for a breach of fiduciary duty.
The Series A Preferred Stock represent perpetual equity interests in us, and investors should not expect us to redeem the Series A Preferred Stock on the date the Series A Preferred Stock becomes redeemable by us or on any particular date afterwards.
The Series A Preferred Stock represent perpetual equity interests in us, and they The Series A Preferred Stock represents a perpetual equity interest in us, and the securities have no maturity or mandatory redemption date and are not redeemable at the option of investors under any circumstances. As a result, unlike our indebtedness, the Series A Preferred Stock will not give rise to a claim for payment of a principal amount at a particular date. As a result, holders of the Series A Preferred Stock may be required to bear the financial risks of an investment in the Series A Preferred Stock for an indefinite period of time. In addition, the Series A Preferred Stock will rank junior to all our current and future indebtedness (including indebtedness outstanding under the Senior Credit Facility) and other liabilities. The Series A Preferred Stock will also rank junior to any other preferred stock ranking senior to the Series A Preferred Stock we may issue in the future with respect to assets available to satisfy claims against us.
The Series A Preferred Stock is not rated.
We have not sought to obtain a rating for the Series A Preferred Stock, and the Series A Preferred Stock may never be rated. It is possible, however, that one or more rating agencies might independently determine to assign a rating to the Series A Preferred Stock or that we may elect to obtain a rating of the Series A Preferred Stock in the future. In addition, we may elect to issue other securities for which we may seek to obtain a rating. If any ratings are assigned to the Series A Preferred Stock in the future or if we issue other securities with a rating, such ratings, if they are lower than market expectations or are subsequently lowered or withdrawn, could adversely affect the market for or the market value of the Series A Preferred Stock. Ratings only reflect the views of the issuing rating agency or agencies and such ratings could at any time be revised downward or withdrawn entirely at the discretion

of the issuing rating agency. A rating is not a recommendation to purchase, sell or hold any particular security, including the Series A Preferred Stock. Ratings do not reflect market prices or suitability of a security for a particular investor and any future rating of the Series A Preferred Stock may not reflect all risks related to us and our business, or the structure or market value of the Series A Preferred Stock.
The Change of Control Conversion Right may make it more difficult for a party to acquire us or discourage a party from acquiring us.
The Change of Control Conversion Right of the Series A Preferred Stock provided in the Certificate of Designation may have the effect of discouraging a third party from making an acquisition proposal for us or of delaying, deferring or preventing certain of our change of control transactions under circumstances that otherwise could provide the holders of our Series A Preferred Stock with the opportunity to realize a premium over the then-current market price of such equity securities or that stockholders may otherwise believe is in their best interests.
If we are unable to redeem the Series A Preferred Stock on or after April 15, 2022, a substantial increase in the Three-Month LIBOR Rate could negatively impact our ability to pay dividends on the Series A Preferred Stock and Class A common stock.

Table of Contents

If we do not repurchase or redeem our Series A Preferred Stock on or after April 15, 2022, a substantial increase in the Three-Month LIBOR Rate could negatively impact our ability to pay dividends on the Series A Preferred Stock. An increase in the dividends payable on our Series A Preferred Stock would negatively impact dividends on our and Class A common stock. We cannot assure you that we will have adequate sources of capital to repurchase or redeem the Series A Preferred Stock on or after April 15, 2022. If we are unable to repurchase or redeem the Series A Preferred Stock and our ability to pay dividends on the Series A Preferred Stock and Class A common stock is negatively impacted, the market value of the Series A Preferred Stock and Class A common stock could be materially adversely impacted.
We may not have sufficient earnings and profits in order for dividends on the Series A Preferred Stock to be treated as dividends for U.S. federal income tax purposes.
The dividends payable by us on the Series A Preferred Stock may exceed our current and accumulated earnings and profits, as calculated for U.S. federal income tax purposes. If this occurs, it will result in the amount of the dividends that exceed such earnings and profits being treated for U.S. federal income tax purposes first as a return of capital to the extent of the beneficial owner's adjusted tax basis in the Series A Preferred Stock, and the excess, if any, over such adjusted tax basis as capital gain. Such treatment will generally be unfavorable for corporate beneficial owners and may also be unfavorable to certain other beneficial owners.
You may be subject to tax if we make or fail to make certain adjustments to the conversion rate of the Series A Preferred Stock even though you do not receive a corresponding cash dividend.
The Conversion Rate as defined in the Certificate of Designation for the Series A Preferred Stock is subject to adjustment in certain circumstances. A failure to adjust (or to adjust adequately) the Conversion Rate after an event that increases your proportionate interest in us could be treated as a deemed taxable dividend to you. If you are a non-U.S. holder, any deemed dividend may be subject to U.S. federal withholding tax at a 30% rate, or such lower rate as may be specified by an applicable treaty, which may be set off against subsequent payments on the Series A Preferred Stock. In April 2016, the Internal Revenue Service issued new proposed income tax regulations in regard to the taxability of changes in conversion rights that will apply to the Series A Preferred Stock when published in final form and may be applied to us before final publication in certain instances.

We are the subject of lawsuits and claims arising in the ordinary course of business from time to time. Management cannot predict the ultimate outcome of such lawsuits and claims. While the lawsuits and claims are asserted for amounts that may be material, should an unfavorable outcome occur, management does not currently expect that any currently pending matters will have a material adverse effect on our financial position or results of operations except as described in Part II, Item 8 "Financial Statements and Supplementary Data," Note 14 "Commitment and Contingencies" to the audited consolidated financial statements, which are incorporated herein by reference.to Part II, Item 8 "Financial Statements and Supplementary Data" of this Form 10-K.

The Company is the subject of the following lawsuits:
John Melville et al v. Spark Energy Inc. and Spark Energy Gas, LLC is a purported class action filed on December 17, 2015 in the United States District Court for the District of New Jersey alleging, among other things, that (i) sales representatives engaged as independent contractors for Spark Energy Gas, LLC engaged in deceptive acts in violation of the New Jersey Consumer Fraud Act, and (ii) Spark Energy Gas, LLC breached its contract with plaintiff, including a breach of the covenant of good faith and fair dealing. On September 5, 2017, the parties reached a confidential settlement in this matter, which the Company expensed and paid in the fourth quarter of 2017.
Halifax-American Energy Company, LLC et al v. Provider Power, LLC, Electricity N.H., LLC, Electricity Maine, LLC, Emile Clavet and Kevin Dean is a lawsuit initially filed on June 12, 2014, in the Rockingham County Superior Court, State of New Hampshire, alleging various claims related to the Provider Companies' employment of a sales contractor formerly employed with one or more of the plaintiffs, including misappropriation of trade secrets and tortious interference with a contractual relationship. The relief sought included compensatory and punitive damages and attorney's fees. The dispute occurred prior to the Company's acquisition of the Provider Companies. Portions of the original claim proceeded to trial and on January 19, 2016, a jury found in favor of the plaintiffs. Damages totaling approximately $0.6 million and attorneys' fees totaling approximately $0.3 million were awarded to the plaintiffs. On May 4, 2016, following post-verdict motions, the defendants filed an appeal in the State of New Hampshire Supreme Court, appealing, among other things the failure of the trial court to direct a verdict for the defendants, to set aside the verdict, or grant judgment for the defendants, and the trial court's award of certain attorneys' fees. The appellate hearing was held on June 1, 2017. The New Hampshire Supreme Court decided the appeal on February 9, 2018, upholding the jury's verdict and the trial court's rulings in all respects. As of December 31, 2017 , the Company has accrued approximately $1.0 million in contingent liabilities related to this litigation. Initial damages and attorneys' fees have been factored into the purchase price for the Provider Companies, and the Company believes it has full indemnity coverage for any actual exposure in this appeal.
Katherine Veilleux and Jennifer Chon, individually and on behalf of all other similarly situated v. Electricity Maine. LLC, Provider Power, LLC, Spark HoldCo, LLC, Kevin Dean and Emile Clavet is a purported class action lawsuit filed on November 18, 2016 in the United States District Court of Maine, alleging that Electricity Maine, LLC, an entity acquired by Spark HoldCo, LLC in mid-2016, enrolled and re-enrolled customers through fraudulent and misleading advertising, promotions, and other communications prior to the acquisition. Plaintiffs further allege that some improper enrollment and re-enrollment practices have continued to the present date. Plaintiffs allege the following claims against all defendants: violation of the Maine Unfair Trade Practices Act, violation of RICO, negligence, negligent misrepresentation, fraudulent misrepresentation, unjust enrichment and breach of contract. Plaintiffs seek unspecified damages for themselves and the purported class, rescission of contracts with Electricity Maine, injunctive relief, restitution, and attorney's fees. By order dated November 15, 2017, the Court, pursuant to Rule 12(b)(6), dismissed all claims against Spark HoldCo except the claims for violation of the Maine Unfair Trade Practices Act and for unjust enrichment. Discovery limited to issues relevant to class certification under Rule 23 of the Federal Rules of Civil Procedure has just begun. Spark HoldCo intends to vigorously defend this matter and the allegations asserted therein, including the request to certify a class. Given the early stages of this matter, we cannot predict the outcome or consequences of this case at this time. The Company believes it is fully indemnified for this litigation matter, subject to certain limitations.

Gillis et al. v. Respond Power, LLC is a purported class action lawsuit that was originally filed on May 21, 2014 in the Philadelphia Court of Common Pleas. On June 23, 2014, the case was removed to the United States District Court for the Eastern District of Pennsylvania. On September 15, 2014, the plaintiffs filed an amended class action complaint seeking a declaratory judgment that the disclosure statement contained in Respond Power, LLC's variable rate contracts with Pennsylvania consumers limited the variable rate that could be charged to no more than the monthly rate charged by the consumers' local utility company. The plaintiffs also allege that Respond Power, LLC (i) breached its variable rate contract with Pennsylvania consumers, and the covenant of good faith and fair dealing therein, by charging rates in excess of the monthly rate charged by the consumers' local utility company; (ii) engaged in deceptive conduct in violation of the Pennsylvania Unfair Trade Practices and Consumer Protection Law; and (iii) engaged in negligent misrepresentation and fraudulent concealment in connection with purported promises of savings. The amount of damages sought is not specified. By order dated August 31, 2015, the district court denied class certification. The plaintiffs appealed the district court's denial of class certification to the United States Court of Appeals for the Third Circuit. The United States Court of Appeals for the Third Circuit vacated the district court's denial of class certification and remanded the matter to the district court for further proceedings. The district court ordered briefing on defendant's motion to dismiss. Respond Power LLC filed a motion to dismiss the plaintiffs' declaratory judgment and breach of contract claims (the class claims) on June 30, 2017. The motion is fully briefed and submitted, and the parties are awaiting a decision from the Court. The Company currently cannot predict the outcome or consequences of this case at this time.

Jurich v. Verde Energy USA, Inc ., is a purported class action originally filed on March 3, 2015 in the United States District Court for the District of Connecticut and subsequently re-filed on October 8, 2015 in the Superior Court of Judicial District of Hartford, State of Connecticut. The Amended Complaint asserts that the Verde Companies charged rates in violation of its contracts with Connecticut customers and alleges (i) violation of the Connecticut Unfair Trade Practices Act and (ii) breach of the covenant of good faith and fair dealing. Plaintiffs are seeking unspecified actual and punitive damages for the purported class and injunctive relief. The parties have exchanged initial discovery. Plaintiffs' motion for class certification was briefed and the Verde Companies filed its opposition to plaintiffs' motion for class certification on October 17, 2017. On December 6, 2017, the Court granted the plaintiffs' class certification motion. However, the Court opted not to send out class notices, and instead directed the parties to submit briefing on legal issues that could result in a modification or decertification of the class. The parties have proposed to the Court that initial briefing on such motions would be due March 16, 2018. As part of an agreement in connection with the acquisition of the Verde Companies, the original owners of the Verde Companies are handling this matter. Given the early stage of this matter, we cannot predict the outcome or consequences of this case at this time. The Company believes it is fully indemnified for this litigation matter by the original owners of the Verde Companies, subject to certain limitations.
Richardson et al v. Verde Energy USA, Inc. is a purported class action filed on November 25, 2015 in the United States District Court for the Eastern District of Pennsylvania alleging that the Verde Companies violated the Telephone Consumer Protection Act by placing marketing calls using an automatic telephone dialing system or a prerecorded voice to the purported class members' cellular phones without prior express consent and by continuing to make such calls after receiving requests for the calls to cease. Plaintiffs are seeking statutory damages for the purported class and injunctive relief prohibiting Verde Companies' alleged conduct. Discovery on the claims of the named plaintiffs closed on November 10, 2017, and dispositive motions on the named plaintiffs' claims was filed on November 24, 2017. Plaintiffs' response to dispositive motions' pleadings was filed on December 22, 2017 and Verde Companies' reply briefs were filed on January 5, 2018.

Overview

We are an independent retail energy services company founded in 1999 that provides residential and commercial customers in competitive markets across the United States with an alternative choice for their natural gas and electricity. We purchase our natural gas and electricity supply from a variety of wholesale providers and bill our customers monthly for the delivery of natural gas and electricity based on their consumption at either a fixed or variable price. Natural gas and electricity are then distributed to our customers by local regulated utility companies through their existing infrastructure. As of December 31, 2018 , we operated in 94 utility service territories across 19 states and the District of Columbia.
Our business consists of two operating segments:

| | |
| • | Retail Electricity Segment . In this segment, we purchase electricity supply through physical and financial transactions with market counterparts and ISOs and supply electricity to residential and commercial consumers pursuant to fixed-price and variable-price contracts. For the years ended December 31, 2018 , 2017 and 2016 , approximately 86% , 82% and 76% 2017 , 2016 and 2015 , approximately 82% , 76% and 64% , respectively, of our retail revenues were derived from the sale of electricity. |

| | |
| • | Retail Natural Gas Segment . In this segment, we purchase natural gas supply through physical and financial transactions with market counterparties and supply natural gas to residential and commercial consumers pursuant to fixed-price and variable-price contracts. For the years ended December 31, 2017 , 2016 and 2015 , approximately 18% , 24% and 36% 2018 , 2017 and 2016 , approximately 14% , 18% and 24% , respectively, of our retail revenues were derived from the sale of natural gas.

Table of Contents

On March 7, 2018, we, Retailco Services and NuDevco Retail mutually agreed to terminate the Master Services Agreement, effective April 1, 2018.

Under the terms of the termination agreement, operational support services will be transferred back to the Company, which may allow us to extract further savings by eliminating overhead attributable to managing and accounting for Retailco Services as a stand-alone business. Please see "Item 9B-Other Information-Termination of Master Service Agreement" for a more detailed description.

Across our market areas, we have operated under a number of different retail brands. During 2018, we began consolidating brands and billing systems. In 2019, we expect to further consolidate our brands and systems as we simplify our business.

Drivers of Our Business

The success of our business and our profitability are impacted by a number of drivers, the most significant of which are discussed below.

Customer Growth

Customer growth is a key driver of our operations. Our customer growth strategy includes acquiring customers through acquisitions. as well as organically.growing organically through traditional sales channels complemented by customer portfolio and business acquisitions. During 2018, we added a total of approximately 432,000 RCEs, of which 29,000 RCEs were added as part of the acquisitions of HIKO Energy, LLC ("HIKO"), 52,000 RCEs were added as a result of customer portfolio acquisitions from Starion Energy Inc. ("Starion") and from an affiliated company, and the remaining were added were through our organic sales channels.

Organic Sales

Our organic sales strategies are used to both maintain and grow our customer base by offering designed to offer competitive pricing, price certainty, and/or green product offerings to residential and commercial customers. We manage growth on a market-by-market basis by developing price curves in each of the markets we serve and comparing the market prices to the price offered by the local regulated utility. is offering. We then determine if there is an opportunity in a particular market based on our ability to create a competitive product on economic terms that provides customer value and satisfies our profitability objectives. and provides customer value. We develop marketing campaigns using a combination of sales channels. with an emphasis on door-to-door marketing and outbound telemarketing given their flexibility and historical effectiveness. We identify and acquire customers through a variety of additional sales channels, including our inbound customer care call center, online marketing, email, direct mail, affinity programs, direct sales, brokers and consultants. Our marketing team continuously evaluates the effectiveness of each customer acquisition channel and makes adjustments in order to achieve desired growth and profitability targets.

In 2017, we emphasized growing our commercial and industrial ("C&I") customer base. After significant growth in our C&I customer count in 2017, management is rebalancing our mix of customers in the first part of 2018 to focus on higher margin residential customers.

We believe we can continue to grow organically, however achieving significant organic growth rates has become increasingly more difficult given our size, much of which is attributable to recent acquisitions. Additionally, increasing regulatory pressure on marketing channels such as door-to-door and outbound telemarketing and the ability to manage customer acquisition costs are significant factors in our ability to grow organically.

Acquisitions

We independently acquire companies and portfolios of companies through some combination of cash, borrowings under the Senior Credit Facility, the issuance of common or preferred stock or other financing arrangements with our Founder and his affiliates. Additionally, our Founder formed National Gas & Electric, LLC, an affiliate of the Company ("NG&E"), In 2015 for the purpose of purchasing retail energy companies and retail customer books that could ultimately be resold to us. we currently expect that we would fund any future transaction with NG&E using some combination of cash, subordinated debt, or the issuance of Class A common stock or Class B common stock (and corresponding Spark HoldCo units) to NG&E. However, actual consideration will depend, among other things, on our capital structure and liquidity at the time of any transaction. There is no guarantee that NG&E will continue to offer us acquisition opportunities. Additionally, as we grow and our access to capital and opportunities improves, we may rely less upon NG&E as a source of acquisitions and seek to enter into more transactions directly with third parties. See "Business and Properties-Relationship with our Founder and Majority Shareholder" for further discussion.customers through both external and affiliated channels. In 2016, we acquired approximately 341,000 RCEs through our acquisitions of Provider Power, LLC ("Provider Power") and Major Energy Companies ("Major Energy"). In 2017, we acquired approximately 206,000 RCEs through

Please see "-Recent Developments-Acquisition of HIKO" and "-Recent Developments-Acquisition of Customers from NG&E" for a description of our recent acquisitions of HIKO Energy, LLC and additional customers from NG&E. For a summary of other historical acquisitions, including those with our Founder and NG&E, please see "Business and Properties-Customer Acquisition and Retention-Acquisitions."
acquisitions of Verde Energy USA Holdings, LLC ("Verde Energy"), Perigee Energy, LLC ("Perigee Energy"), and a customer portfolio. In 2018, we have added approximately 81,000 RCEs through our acquisitions of HIKO, a customer portfolio from an affiliate, and a customer portfolio from Starion.


We are actively monitoring acquisition opportunities that may arise In the domestic acquisition market as smaller retailers face difficulties in managing risk and liquidity issues caused by the recent extreme weather patterns.
our ability to grow at historic levels may be constrained if the market for acquisition candidates is limited and we are unable to make acquisitions of portfolios of customers and retail energy companies on commercially reasonable terms.


Integration of Acquisitions

Effective integration of Our acquisitions is a key driver of our business. We integrated both CenStar and Oasis and began recognizing synergies in 2015. We were able to integrate the Provider Companies and begin recognizing synergies in 2016. The integration of the Perigee acquisition is progressing well and synergies are being recognized as of December 31, 2017. As the Major Energy Companies Earnout extends over multiple years, the Company is not able to achieve full synergies at this time. We were able to terminate the earnout related to our acquisition of the Verde Companies, allowing us to begin integrating the Verde Companies in early 2018. See "-Recent Developments" above. for a summary of historical acquisitions.please see "Business and Properties-Customer Acquisition and Retention-Acquisitions."
Our ability to realize returns from acquisitions that are acceptable to us is dependent on our ability to successfully identify, negotiate for finance and integrate acquisitions.

Our 35% net RCE growth in 2017 reflects our acquisition of Verde Companies and Perigee, which added approximately 162,000 RCEs, or 21% net growth. The remaining 14% net RCE growth in 2017 was the result of organic additions and customer portfolio acquisitions.

Our 87% net RCE growth in 2016 reflects our acquisitions of Major and Provider, which added approximately 341,000 RCEs, or 82% net growth. The remaining 5% net RCE growth in 2016 was the result of organic additions.

Our 27% net RCE growth in 2015 reflects our acquisitions of CenStar and Oasis, which resulted in an increase in the overall size of individual customers. This growth was partially offset by the slowing of organic Additions as we shifted our focus to acquisitions and renegotiated our mass market vendor commission structure in the third quarter of 2015, which correlated commission payments with customer value. These efforts had the effect of resetting our vendor relationships, which in turn slowed organic growth as vendors adapted to the new structure.

Management of customer acquisition costs is a key component to our profitability. Customer acquisition costs are spending for organic customer acquisitions and does not include customer acquisitions through acquisitions of businesses or portfolios of customer contracts, which are recorded as customer relationships.

We attempt to maintain a disciplined approach to recovery of our customer acquisition costs within defined periods. We capitalize and amortize our customer acquisition costs over a two year period, which is based on The expected average length of a customer relationship. We factor in the recovery of customer acquisition costs in determining which markets we enter and the pricing of our products in those markets. Accordingly, our results are significantly influenced by our customer acquisition spending.
The increase of our RCE counts in 2016 and 2017 related to the acquisition of customers and businesses in excess of natural customer attrition during those years. In 2018, our attrition exceeded customer adds due to lower organic sales spending, fewer acquisitions and slightly higher attrition impacted by our brand consolidation activities and our intentional non-renewable of certain larger C&I customer contracts. Average monthly attrition rates during 2016 , 2017 , and 2018 were as follows:


Customer acquisition costs incurred for the year ended December 31, 2017 was approximately $25.9 million , inclusive of costs attributable to Perigee and the Verde Companies incurred subsequent to their respective acquisition dates.

Customer acquisition costs incurred for the year ended December 31, 2016 was approximately $24.9 million , inclusive of costs attributable to the Provider Companies and Major Energy Companies incurred subsequent to their respective acquisition dates. During the first half of 2016, we reduced the amount we spent on organic customer acquisition costs in order to maintain, rather than grow, our current level of RCEs, and shifted our resources to acquiring companies and entire books of customers. during the second half of 2016, we increased our spending on organic customer acquisitions as we refocused on organic growth.

Our customer acquisition spending, in the second half of 2015 slowed, resulting in customer acquisition costs of $19.9 million in 2015 as we shifted our focus to acquisitions and due to changes to our residential vendor commission payment structure to better align them with lifetime customer value.

Customer attrition occurs primarily as a result of:
Customer attrition is primarily due to: (i) customer initiated switches; (ii) residential moves and (iii) disconnection for customer payment defaults.

Customer attrition during the year ended December 31, 2017 was in line with the previous year as we continued our focus on the Acquisition of higher lifetime value customers. We also continued our Customer win-back efforts, and 2018 was slightly higher than the prior year due to brand consolidations and our intentional non-renewal of certain large C&I contracts.

Customer Acquisition Costs

Managing customer acquisition costs is a key component of our profitability. Customer acquisition costs are those costs related to obtaining customers organically and do not include the cost of acquiring customers through acquisitions, which are recorded as customer relationships. For each of the three years ended December 31, 2018 , customer acquisition costs were as follows:

We attempt to maintain a disciplined approach to recovery of our customer acquisition costs within a 12 month period. We capitalize and amortize our customer acquisition costs over a two year period, which is based on our estimate of the expected average length of a customer relationship. We factor in the recovery of customer acquisition costs in determining which markets we enter and the pricing of our products in those markets. Accordingly, our results are significantly influenced by our customer acquisition costs. Changes in customer acquisition costs from period to period reflect our focus on growing organically versus growth through acquisitions. We are currently focused on growing through organic sales channels although we continue to evaluate opportunities to acquire customers through acquisitions where they make sense economically or strategically.

Customer Credit Risk

Approximately 66% of our revenues are derived from customers in utilities where customer credit risk is borne by the utility in exchange for a discount on amounts billed. Where we have customer credit risk, we record bad debt based on an estimate of uncollectible amounts. Our bad debt expense on non-POR revenues was as follows:
| |
| | | | | | | |
| | Year Ended December 31 |
| | 2018 | 2017 | 2016 | 2015 |
| Total Non-POR Bad Debt as Percent of Revenue | 2.6 | % | 2.5 | % | 0.6 | % |

During the year ended December 31, 2018 , we experienced higher bad debt expense versus 2017 primarily as a result of our brand consolidations. During the year ended December 31, 2017 , we experienced higher bad debt expense versus 2016 due to Hurricane Harvey, coupled with the fact that the year ended December 31, 2016 included a reversal of a portion of our bad debt reserve as a result of improved collection efforts. 2017 we experienced increased bad debt expense due to Hurricane Harvey,

To manage our current exposure, we have increased our focus on collection efforts and timely billing along with tighter credit requirements for new enrollments in non-POR marketshave led to a reduction in the bad debt expense in 2016 as compared to 2015. We have also been able to collect on debt that we had previously written off, which further reduced our bad debt expense during 2016.

Bad debt expense as a percentage of non-POR market retail revenues remained high in 2015 due to the negative impact of higher attrition in the Midwest natural gas markets and continued disconnections for non-payment from our Southern California portfolio, where we stopped selling in January 2015. In early 2016, we introduced upfront credit screening to many of our natural gas sales campaigns in order to proactively identify potential at-risk customers.

For the years ended December 31, 2017 , 2016 and 2015 , approximately 66% , 67% and 56% 2018 , 2017 and 2016 , approximately 66% , 66% and 67% , respectively, of our retail revenues were collected through POR programs where substantially all of our credit risk was with local regulated utility companies. As of December 31, 2018 , 2017 and 2016 , all of these local regulated utility companies had investment grade ratings. During these same periods, we paid these local regulated utilities a weighted average discount of approximately 1.0% , 1.1% and 1.3% , respectively, of total revenues for customer credit risk protection.respectively.

Weather Conditions

Weather conditions directly influence the demand for natural gas and electricity and affect the prices of energy commodities. Our hedging strategy is based on forecasted customer energy usage, which can vary substantially as a result of weather patterns deviating from historical norms. We are particularly sensitive to this variability because of our current substantial concentration and focus on growth in the in our residential customer segment in which energy usage is highly sensitive to weather conditions that impact heating and cooling demand.In the first three quarters of 2017, we experienced milder than anticipated weather conditions, which negatively impacted overall customer usage, but allowed us to optimize our costs of revenues as commodity prices fell. In the third quarter of 2017, Hurricane Harvey caused historic flooding, extensive damage and widespread power outages across the Gulf Coast of Texas. Although We did not suffer physical damage to our Houston offices, the hurricane negatively impacted our ability to serve our customers and deliver electricity in this region during the hurricane and for the following weeks. we recorded losses of approximately $0.7 million for the year ended December 31, 2017, directly attributable to Hurricane Harvey, primarily related to bad debt expense.

Our risk management policies direct that we hedge substantially all of our forecasted demand, which is typically hedged to long-term normal weather patterns. We also attempt to add additional contracts from time to time to protect us from volatility in markets where we have historically experienced higher exposure to extreme weather conditions. Because we attempt to match commodity purchases to anticipated demand, unanticipated changes in weather patterns can have a significant impact on our operating results and cash flows from period to period.


in late 2017 and early 2018, the Northeastern and Great Lake regions experienced extreme weather patterns We expect excessive customer usage from this cold weather may negatively impact our results of operations.


In the first half of 2016, we experienced milder than anticipated weather conditions, which negatively impacted overall customer usage, but allowed us to optimize our costs of revenues as commodity prices fell. In the second half of 2016, we experienced marginally warmer than normal weather conditions.

In the early part of 2015, colder than anticipated weather increased volumes and thus positively impacted Our first quarter earnings. Warmer than normal weather in the fourth quarter of 2015 in the Northeast negatively impacted natural gas volumes, while we also optimized our costs of revenues as commodity prices fell.
Our


Asset Optimization

Our natural gas business includes opportunistic transactions in the natural gas wholesale marketplace in conjunction with our retail procurement and hedging activities. asset optimization opportunities primarily arise during the winter heating season when demand for natural gas is the highest. As such, the majority of our asset optimization profits are made in the winter.typically at its highest. Given the opportunistic nature of these activities and because we account for these activities using the mark to market method of accounting, we experience variability in our earnings from our asset optimization activities from year to year.As these activities are accounted for using mark-to-market accounting, the timing of our revenue recognition often differs from the actual cash settlement.

During each of the years ended December 31, 2017 and 2016 , we were obligated to pay demand charges of approximately $2.6 million under certain long-term legacy transportation assets that our predecessor entity acquired prior to 2013. Although these demand payments will decrease over time, a portion of the related capacity agreements extend through 2028. Net asset optimization results were a gain of $4.5 million , a loss of $0.7 million and a loss of $0.6 million for the years ended December 31, 2018 , 2017 and 2016 , respectively.

Factors Affecting Comparability of Historical Financial Results
Non-GAAP Performance Measures

Tax Receivable Agreement. We entered into the Tax Receivable Agreement between us and Spark Holdco, NuDevco Retail Holdings and NuDevco Retail concurrently with the IPO, which provides for the payment by us to Retailco, LLC (as successor to NuDevco Retail Holdings) and NuDevco Retail of 85% of the net cash savings, if any, in U.S. federal, state and local income tax or franchise tax that we actually realize (or are deemed to realize in certain circumstances) in future periods as a result of certain events. On December 22, 2017, the President signed the Tax Cuts and Jobs Act ("U.S. Tax Reform"), which enacts a wide range of changes to the U.S. Corporate income tax system, including a reduction in the U.S. corporate tax rate to 21% effective in 2018. The revised corporate income tax rate reduces the amount of net cash savings to be realized in future periods. Therefore, we have reduced the Tax Receivable Agreement liability ("TRA liability") as of December 31, 2017 by $22.3 million to reflect the effect of the U.S. Tax Reform and recorded this adjustment through Other Income. In addition, payments we make under the Tax Receivable Agreement are increased by any interest accrued from the due date (without extensions) of the corresponding tax return. We have recorded 85% of the estimated tax benefit as an increase to amounts payable under the Tax Receivable Agreement as a liability. We retain the benefit of the remaining 15% of These tax savings. As a result of new federal tax laws going into effect in 2018, the Company has re-valued its deferred tax asset and deferred tax liability relating to the Tax Receivable Agreement on its balance sheet as of December 31, 2017. The effect of these downward adjustments is a net increase in income tax expense for the year ended December 31, 2017. See Note 12 "Income Taxes" for further discussion.
We use the Non-GAAP performance measures of Adjusted EBITDA and Retail Gross Margin to evaluate and measure our operating results. These measures for the three years ended December 31, 2018 were as follows:


Executive Compensation Programs. Periodically the Company grants restricted stock units to our officers, employees, non-employee directors and certain employees of our affiliates who perform services for the Company. The restricted stock unit awards vest over approximately one year for non-employee directors and ratably over approximately three or four years for officers, employees and employees of affiliates, with the initial vesting date occurring in May of the subsequent year, and include tandem dividend equivalent rights that will vest upon the same schedule as the underlying restricted stock unit.

Financing . We are party to the Senior Credit Facility. Historical borrowings under the Senior Credit Facility may not provide an accurate indication of what we need to operate our natural gas and electricity business. For a description of our current Senior Credit Facility, please see "-Liquidity and Capital Resources-Sources of Liquidity."

Adjusted EBITDA . We define "Adjusted EBITDA" as EBITDA less (i) customer acquisition costs incurred in the current period, plus or minus (ii) net gain (loss) on derivative instruments, and (iii) net current period cash settlements on derivative instruments, plus (iv) non-cash compensation expense, and (v) other non-cash and non-recurring operating items. EBITDA is defined as net income (loss) before the provision for income taxes, interest expense and depreciation and amortization.

We deduct all current period customer acquisition costs (representing spending for organic customer acquisitions) in the Adjusted EBITDA calculation because such costs reflect a cash outlay in the period in which they are incurred, even though we capitalize such costs and amortize them over two years. in accordance with our accounting policies. The deduction of current period customer acquisition costs is consistent with how we manage our business, but the comparability of Adjusted EBITDA between periods may be affected by varying levels of customer acquisition costs. For example, our Adjusted EBITDA is lower in periods of organic customer growth reflecting larger customer acquisition spending.and amortize such costs over two years.

Table of Contents

We do not deduct the cost of customer acquisitions through acquisitions of businesses or portfolios of customers in calculating Adjusted EBITDA.

We deduct our net gains (losses) on derivative instruments, excluding current period cash settlements, from the Adjusted EBITDA calculation in order to remove the non-cash impact of net gains and losses on these instruments. We also deduct non-cash compensation expense as a result of restricted stock units that are issued that results from the issuance of restricted stock units under our long-term incentive plan due to the non-cash nature of the expense. Finally, we also adjust from time to time other non-cash or unusual and/or infrequent charges due to either their non-cash nature or their infrequency.

We believe that the presentation of Adjusted EBITDA provides information useful to investors in assessing our liquidity and financial condition and results of operations and that Adjusted EBITDA is also useful to investors as a financial indicator of our ability to incur and service debt, pay dividends and fund capital expenditures. Adjusted EBITDA is a supplemental financial measure that management and external users of our consolidated financial statements, such as industry analysts, investors, commercial banks and rating agencies, use to assess the following:

| | |
| • | our operating performance as compared to other publicly traded companies in the retail energy industry, without regard to financing methods, capital structure or historical cost basis; |
| | |
| • | the ability of our assets to generate earnings sufficient to support our proposed cash dividends; and |
| | |
| • | our ability to fund capital expenditures (including customer acquisition costs) and incur and service debt. |

Retail Gross Margin. We define retail gross margin as operating income plus (i) depreciation and amortization expenses and (ii) general and administrative expenses, less (iii) net asset optimization revenues, (iv) net gains (losses) on non-trading derivative instruments, and (v) net current period cash settlements on non-trading derivative instruments. Retail gross margin is included as a supplemental disclosure because it is a primary performance measure used by our management to determine the performance of our retail natural gas and electricity business by removing the impacts of our asset optimization activities and net non-cash income (loss) impact of our economic hedging activities. As an indicator of our retail energy business' operating performance, retail gross margin should not be considered an alternative to, or more meaningful than, operating income, its most directly comparable financial measure calculated and presented in accordance with GAAP.

We believe retail gross margin provides information useful to investors as an indicator of our retail energy business's operating performance.

The GAAP measures most directly comparable to Adjusted EBITDA are net income and net cash provided by operating activities. The GAAP measure most directly comparable to Retail Gross Margin is operating income (loss). Our non-GAAP financial measures of Adjusted EBITDA and Retail Gross Margin should not be considered as alternatives to net income (loss), net cash provided by operating activities, or operating income (loss). Adjusted EBITDA and Retail Gross Margin are not presentations made in accordance with GAAP and have important limitations as analytical tools. You should not consider Adjusted EBITDA or Retail Gross Margin in isolation or as a substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA and Retail Gross Margin exclude some, but not all, items that affect net income (loss), net cash provided by operating activities, and operating income (loss), and are defined differently by different companies in our industry, our definition of Adjusted EBITDA and Retail Gross Margin may not be comparable to similarly titled measures of other companies.
Management compensates for the limitations of Adjusted EBITDA and Retail Gross Margin as analytical tools by reviewing the comparable GAAP measures, understanding the differences between the measures and incorporating these data points into management's decision-making process.

trading derivative instruments. Retail gross margin is included as a supplemental disclosure because it is a primary performance measure used by our management to determine the performance of our retail natural gas and electricity segments. As an indicator of our retail energy business' operating performance, retail gross margin should not be considered an alternative to, or more meaningful than, operating income (loss), its most directly comparable financial measure calculated and presented in accordance with GAAP.

We believe retail gross margin provides information useful to investors as an indicator of our retail energy business's operating performance.

The GAAP measure most directly comparable to Retail Gross Margin is operating income. The following table presents a reconciliation of Retail Gross Margin to operating income for each of the periods indicated.

Our non-GAAP financial measures of Adjusted EBITDA and Retail Gross Margin should not be considered as alternatives to net (loss) income, net cash provided by operating activities, or operating (loss) income. Adjusted EBITDA and Retail Gross Margin are not presentations made in accordance with GAAP and have limitations as analytical tools. You should not consider Adjusted EBITDA or Retail Gross Margin in isolation or as a substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA and Retail Gross Margin exclude some, but not all, items that affect net (loss) income, net cash provided by operating activities, and operating (loss) income, and are defined differently by different companies in our industry, our definition of Adjusted EBITDA and Retail Gross Margin may not be comparable to similarly titled measures of other companies.
Management compensates for the limitations of Adjusted EBITDA and Retail Gross Margin as analytical tools by reviewing the comparable GAAP measures, understanding the differences between the measures and incorporating these data points into management's decision-making process.

Total Revenues. Total revenues for the year ended December 31, 2018 were approximately $1,005.9 million , an increase of approximately $207.8 million , or 26% , from approximately $798.1 million for the year ended December 31, 2017 . This increase was primarily due to an increase in electricity volumes driven by the acquisitions of the HIKO and two customer portfolios, full year results from the Verde Companies, and higher-than-normal electricity and natural gas pricing in 2018, partially offset by a decrease in natural gas volumes due to warmer-than-normal weather in the second and third quarters of 2018. Total revenues for the year ended December 31, 2017 increased approximately $251.4 million , or 46% , from approximately $546.7 million for the year ended December 31, 2016 . This increase was primarily due to an increase in electricity and natural gas volumes driven by full year results of the Major Energy Companies and the Provider Companies which were both acquired in 2016, and by the acquisition of the Verde Companies during 2017, partially offset by decreased electricity pricing.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity are cash generated from operations and borrowings under our Senior Credit Facility. Our principal liquidity requirements are to meet our financial commitments, finance current operations, fund organic growth and/or acquisitions, service debt and pay dividends. Our liquidity requirements fluctuate with our level of customer acquisition costs, acquisitions, collateral posting requirements on our derivative instruments portfolio, distributions, the effects of the timing between payments of payables and receipts of receivables, including bad debt receivables, the settlement of payables and receivables, including the effect of bad debts, weather conditions, and our general working capital needs for ongoing operations.

Our primary sources of liquidity are cash generated from operations and borrowings under our Senior Credit Facility. We believe that cash generated from operations and our available liquidity sources will be sufficient to sustain current operations and to pay required taxes and quarterly cash distributions, including the quarterly dividends to the holders of the Class A common stock and the Series A Preferred Stock, for the next twelve months. We believe that the financing of any additional growth through acquisitions of businesses in 2018, other than those transactions described in "-Recent Developments," or the need for more liquidity in 2019, may require further equity or debt financing and/or further expansion of our Senior Credit Facility. Estimating our liquidity requirements is highly dependent on then-current market conditions, including forward prices for natural gas and electricity, and market volatility and our then existing capital structure and requirements.

Cash Flows Provided by Operating Activities . Cash flows provided by operating activities for the year ended December 31, 2018 decreased by $2.4 million compared to the year ended December 31, 2017 .

Cash flows provided by operating activities for the year ended December 31, 2017 decreased by $4.8 million compared to the year ended December 31, 2016 .

Cash Flows Used in Investing Activities . Cash flows used in investing activities decreased by $58.6 million for the year ended December 31, 2018 .

Cash flows provided by financing activities increased by $44.9 million for the year ended December 31, 2017 primarily due to increased net utilization of our Senior Credit Facility and proceeds from the issuance of Series A Preferred Stock, offset by additional dividends and distributions, respectively, made to holders of our Class A common stock, holders of our Series A Preferred Stock, and holders of the Class B units of Spark HoldCo.

Critical Accounting Policies and Estimates
Our significant accounting policies are described in Note 2 "Basis of Presentation and Summary of Significant Accounting Policies" to our audited consolidated financial statements. We prepare our financial statements in conformity with accounting principles generally accepted in the United States of America and pursuant to the rules and regulations of the SEC, which require us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying footnotes. Actual results could differ from those estimates. We consider the following policies to be the most critical in understanding the judgments that are involved in preparing our financial statements and the uncertainties that could impact our financial condition and results of operations.

Revenue Recognition and Retail Cost of Revenues

Our revenues are derived primarily from the sale of natural gas and electricity to retail customers. We also record revenues from sales of natural gas and electricity to wholesale counterparties, including affiliates. Revenues are recognized by using the following criteria: (1) persuasive evidence of an exchange arrangement exists, (2) delivery has occurred or services have been rendered, (3) the buyer's price is fixed or determinable and (4) collection is reasonably assured. Utilizing these criteria, revenue is recognized when the natural gas or electricity is delivered. Similarly, cost of revenues is recognized when the commodity is delivered.

Revenues for natural gas and electricity sales are recognized upon delivery under the accrual method. Natural gas and electricity sales that have In each period, natural gas and electricity that has been delivered but not billed by period is estimated. Accrued unbilled revenues are based on estimates of customer usage since the date of the last meter read and are provided by the utility. Volume estimates are based on forecasted volumes and estimated customer usage by class. Unbilled revenues are calculated by multiplying these volume estimates by the applicable rate by customer class. Estimated amounts are adjusted when actual usage is known and billed.

The cost of natural gas and electricity for sale to retail customers is similarly based on estimated supply volumes for the applicable reporting period. In estimating supply volumes, we consider the effects of historical customer volumes, weather factors and usage by customer class. Transmission and distribution delivery fees, where applicable, are estimated using the same method used for sales to retail customers. In addition, other load related costs, such as ISO fees, ancillary services and renewable energy credits are estimated based on historical trends, estimated supply volumes and initial utility data. Volume estimates are then multiplied by the supply rate and recorded as retail cost of revenues in the applicable reporting period. Estimated amounts are adjusted when actual usage is known and billed.

Our asset optimization activities, which primarily include natural gas physical arbitrage and other short term storage and transportation opportunities, meet the definition of trading activities and are recorded on a net basis in the consolidated statements of operations in net asset optimization revenues as required by the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging.

Accounts Receivable

Table of Contents

We accrue an allowance for doubtful accounts based upon estimated uncollectible accounts receivable considering historical collections, accounts receivable aging analysis, credit risk and other factors. We write off accounts receivable balances against the allowance for doubtful accounts when the accounts receivable is deemed to be uncollectible.

We conduct Business in many utility service markets where the local regulated utility purchases our receivables, and then becomes responsible for billing the customer and collecting payment from the customer ("POR programs"). This POR service results in substantially all of our credit risk being linked to the applicable utility in these territories, which generally has an investment-grade rating, and not to the end-use customer. We monitor the financial condition of each utility and currently believe that our susceptibility to an individually significant write-off as a result of concentrations of customer accounts receivable with those utilities is remote.
Business Combinations

In markets that do not offer POR services or When we choose to directly bill our customers, certain accounts receivable are billed and collected by us. We bear the credit risk on these accounts and record an appropriate allowance for doubtful accounts to reflect any losses due to non-payment by customers. Our customers are individually insignificant and geographically dispersed in these markets. We write off customer balances when we believe that amounts are no longer collectible and when we have exhausted all means to collect these receivables.
When we acquire a business or a book of customers, we assign and allocate the purchase price


Capitalized Customer Acquisition Costs

Capitalized customer acquisition costs consist primarily of hourly and commission based telemarketing costs, door-to-door agent commissions and other direct advertising costs associated with proven customer generation, and are capitalized and amortized over the estimated two-year average life of a customer in accordance with the provisions of FASB ASC 340-20, Capitalized Advertising Costs .

Recoverability of customer acquisition costs is evaluated based on a comparison of the carrying amount of the customer acquisition costs to the future net cash flows expected to be generated by the customers, acquired, considering specific assumptions for customer attrition, per unit gross profit, and operating costs. These assumptions are based on forecasts and historical experience.

Business Combinations

Accounting Standards Codification ("ASC") 815, Business Combinations requires that the purchase price for a business combination be assigned and allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair value. Generally, the amount recorded in the financial statements for an acquisition's assets and liabilities is equal to the purchase price (the fair value of the consideration paid); however, when the purchase price exceeds the underlying fair value of the net assets acquired, we recognize goodwill. Conversely, a purchase price that is below the fair value of the net assets acquired will result in the recognition of a bargain purchase in the income statement.

In addition to the potential for the recognition of goodwill or a bargain purchase, differing fair values will impact the allocation of the purchase price to the individual assets and liabilities and can impact the gross amount and classification of assets and liabilities recorded in our consolidated balance sheets, which can impact the timing and amount of depreciation and amortization expense recorded in any given period.

In estimating fair value, we use discounted cash flow ("DCF") projections, recent comparable market transactions, if available, or quoted prices. We consider assumptions that third parties would make in estimating fair value,

59

Table of Contents

including, but not limited to, the highest and best use of the asset. There is a significant amount of judgment involved in cash-flow estimates, including assumptions regarding market convergence, discount rates, commodity prices, customer attrition, useful lives and growth factors. The assumptions used by another party could differ significantly from our assumptions.

We utilize our best effort to make our determinations and review all information available, including estimated future cash flows and prices of similar assets when making our best estimate. We also may hire independent

Table of Contents

appraisers or valuation specialists to help us make this determination as we deem appropriate under the circumstances. Refer to Note 4 "Acquisitions" for further discussion of assumptions used in acquisitions.

There is a significant amount of judgment in determining the fair value of acquisitions and in allocating the purchase price to individual assets and liabilities. Had different assumptions been used, the fair value of the assets acquired and liabilities assumed could have been significantly higher or lower with a corresponding increase or reduction in recognized goodwill, or could have required recognition of a bargain purchase.

In the case of acquisitions that involve potential future contingent consideration, we record on the date of acquisition a liability equal to the fair value of the estimated additional consideration we may be obligated to pay in the future. We re-measure this liability each reporting period and record changes in the fair value as general and administrative expense. Increase or decreases in the fair value of the contingent consideration can result from changes in in the timing or likelihood of achieving revenue or customer count thresholds. The use of alternative valuation assumptions, including estimated revenue projections, growth rates, cash flows and discount rates and alternative estimated probabilities surrounding revenue or customer count thresholds could result in different expense related to contingent consideration.
Goodwill

As noted above, Goodwill represents the excess of cost over fair value of the assets of businesses. acquired in accordance with FASB ASC Topic 350 Intangibles-Goodwill and Other ("ASC 350"). The goodwill on our consolidated balance sheet as of December 31, 2018 is associated with both our Retail Natural Gas and Retail Electricity reporting units. We determine our reporting units by identifying each unit that is engaged in business activities from which it may earn revenues and incur expenses, has operating results regularly reviewed by the segment manager for purposes of resource allocation and performance assessment, and has discrete financial information.

Goodwill is assessed for impairment whenever events or circumstances indicate that impairment of the carrying value of goodwill is likely, but no less often than annually. Our annual assessment, absent a triggering event is as
of October 31 of each year. On October 31, 2018 , we elected to
asof October 31 On October 31, 2017, we elected to by-pass the option to perform a qualitative assessment of goodwill and performed a quantitative assessment of goodwill in accordance with guidance from ASC 350. This guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. If we fail the qualitative test or if we elect to by-pass the qualitative assessment, then we must compare our estimate of the fair value of a reporting unit with its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, we perform the second step of the goodwill impairment test to measure the amount of goodwill impairment loss to be recorded, as necessary. The second step compares the implied fair value of the reporting unit's goodwill to the carrying value, if any, of that goodwill. We determine the implied fair value of the goodwill in the same manner as determining the amount of goodwill to be recognized in a business combination. All of these assessments and calculations, including the determination of whether a triggering event has occurred to undertake an assessment of goodwill involve a high degree of judgment.

We completed our annual assessment of goodwill impairment at October 31, 2018, and the test indicated no impairment.

Deferred tax assets and liabilities

The Company recognizes the amount of taxes payable or refundable for each tax year. In addition, the Company follows the asset and liability method of accounting for income taxes where deferred tax assets and liabilities are

60

Table of Contents

recognized for the expected future tax consequences of events that have been recognized in the financial statements or tax returns and operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in those years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in the tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for deferred tax assets if it is more likely than not that these items will not be realized.

78

Table of Contents

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the projected future taxable income and tax planning strategies in making this assessment.

Recent Accounting Pronouncements

Adopted Standards

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) ("ASU 2016-09"). ASU 2016-09 includes provisions intended to simplify various aspects of accounting for shared-based payments, including income tax consequences, classification of awards as either equity or liability and classification on the statement of cash flows. This guidance is effective for annual and interim reporting periods of public entities beginning after December 15, 2016, with early adoption permitted. The Company adopted ASU 2016-09 on January 1, 2017.
All of these determinations involve estimates and assumptions.


The new standard requires prospective recognition of excess tax benefits resulting from stock-based compensation vesting and exercises to be recognized as a reduction of income taxes and reflected in operating cash flows. Previously, these amounts were recognized in additional paid-in capital and presented as a financing activity on the statement of cash flows. Net excess tax benefits of $0.2 million were recognized as a reduction of income taxes for the year ended December 31, 2017 . Prior periods have not been adjusted.

The Company has elected to continue to estimate the number of stock-based awards expected to vest, as permitted by ASU 2016-09, rather than electing to account for forfeitures as they occur.

ASU 2016-09 requires that employee taxes paid when an employer withholds shares for tax-withholding purposes to be reported as financing activities in the statement of cash flows. Previously, these cash flows were included in operating activities. The Company has elected to adopt this prospectively, as permitted by ASU 2016-09. This change resulted in a $1.1 million impact on the statement of cash flow for the year ended December 31, 2017 .

In October 2016, the FASB issued ASU No. 2016-17, Consolidation (Topic 810): Interests Held through Related Parties that Are under Common Control ("ASU 2016-17"). ASU 2016-17 amends the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity ("VIE") should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. Under ASU 2016-17, a single decision maker of a VIE is required to consider indirect economic interests in the entity held through related parties on a proportionate basis when determining whether it is the primary beneficiary of that VIE. If a single decision maker and its related party are under common control, the single decision maker is required to consider indirect interests in the entity held through those related parties to be the equivalent of direct interests in their entirety. The amendments are effective for public business entities for fiscal years beginning after December 15, 2016 (the Company's first quarter of fiscal 2017), including interim periods within those fiscal years. Early adoption is permitted. The standard may be applied retrospectively or through a cumulative effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company adopted ASU 2016-17 effective January 1, 2017, and the adoption had no impact on the Company's consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"). ASU 2016-18 is intended to add and clarify guidance on the classification and presentation of restricted cash on the statement of cash flows. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments are effective for public business entities for fiscal

79

Table of Contents

years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company adopted ASU 2016-18 effective April 1, 2017, and has included restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.

Standards adopted in 2018

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard permits the use of either the retrospective or cumulative effect transition method. In December 2016, the FASB further issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers , to increase stakeholders' awareness of the proposals and to expedite improvements to ASU 2014-09.

The FASB issued additional amendments to ASU No. 2014-09, as amended by ASU No. 2015-14:

| | |
| • | March 2016 - ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) ("ASU 2016-08"). ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to customers. |

| | |
| • | April 2016 - ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ("ASU 2016-10"). ASU 2016-10 covers two specific topics: performance obligations and licensing. This amendment includes guidance on immaterial promised goods or services, shipping or handling activities, separately identifiable performance obligations, functional or symbolic intellectual property licenses, sales-based and usage-based royalties, license restrictions (time, use, geographical) and licensing renewals. |

| | |
| • | May 2016 - ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and Practical Expedients ("ASU 2016-12"). ASU 2016-12 clarifies certain core recognition principles including collectability, sales tax presentation, noncash consideration, contract modifications and completed contracts at transition and disclosures no longer required if the full retrospective transition method is adopted. |

| | |
| • | September 2017 - ASU No. 2017-13, Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments ("ASU 2017-13"). ASU 2017-13 provides additional implementation guidance related to ASC Topic 606 and is effective for annual reporting periods beginning after December 15, 2017. |

| | |
| • | November 2017 - ASU No. 2017-14, Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 116 and SEC Release No. 33-10403 ("ASU 2017-14"). ASU 2017-14 amends various paragraphs in ASC 605, Revenue Recognition ; and ASC 606, Revenue from Contracts With Customers , that contain SEC guidance. The amendments include superseding ASC 605-10-S25-1 (SAB Topic 13) as a result of SEC Staff Accounting Bulletin No. 116 and adding ASC 606-10-S25-1 as a result of SEC Release No. 33-10403. |
Recent Accounting Pronouncements

In 2017, we collaborated with an external professional services firm to analyze the impact of the standard on our contract portfolio by reviewing our current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to our revenue contracts. In addition, we identified and implemented appropriate changes to our business processes, systems and controls to support recognition and disclosure under the new standard.
Refer to Note 2 "Basis of Presentation and Summary of Significant Accounting Policies" for a discussion of recent accounting pronouncements.

Table of Contents

The Company adopted the new standard effective January 1, 2018 utilizing the full retrospective approach. The adoption of the new standard will result in an immaterial impact to our total revenues and operating income for the years ended December 31, 2017 and 2016, since our contracts with customers identify the delivery of products and services that are individually distinct performance obligations and revenue is recognized when performance obligations are satisfied. As a result, receivable balances related to revenue, including amounts related to unbilled revenue, are reflected as accounts receivable in the consolidated balance sheets. No other revenue related contract assets or liabilities are recorded.

The standard requires expanded disclosures regarding the qualitative and quantitative information of an entity's nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

Note the Company's asset optimization activities meet the definition of trading activities per FASB ASC Topic 815, Derivatives and Hedging, and are therefore excluded from the scope of Revenue from Contracts with Customers (Topic 606) .


In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). ASU 2016-15 provides guidance on the Presentation and classification of eight specific cash flow issues in the statement of cash flows. Those issues are cash payment for debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instrument or other debt instrument with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; cash proceeds from the settlement of insurance claims, cash received from settlement of corporate-owned life insurance Policies" distribution received from equity method investees; beneficial interest in securitization transactions; and classification of cash receipts and payments that have aspects of more than one class of cash flows. The guidance is effective for interim and annual reporting periods beginning after December 15, 2017. This ASU is to be applied using a retrospective transition method for each period presented. The Company adopted ASU 2016-15 effective January 1, 2018 and will classify contingent consideration payments made after a business combination as cash outflows for operating and financing activities on a retrospective basis. Because of the change in accounting guidance, we expect to reclassify acquisition related payments of approximately $1.8 million and $0.8 million from cash flows from investing activities to cash flows from operating activities for the years ended December 31, 2017 and December 31, 2016, respectively. We expect to reclassify acquisition related payments of approximately $18.4 million and $2.0 million from cash flows from investing activities to cash flows from financing activities for the years ended December 31, 2017 and December 31, 2016, respectively.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory ("ASU 2016-16"). ASU 2016-16 requires immediate recognition of the current and deferred income tax consequences of intercompany asset transfers other than inventory. Current U.S. GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. This guidance is effective for annual and interim reporting periods of public entities beginning after December 15, 2017. This ASU is to be applied using a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company adopted ASU 2016-16 effective January 1, 2018 and the adoption of this standard will not have an impact on the Company's consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business ("ASU 2017-01"). ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting, including acquisitions, disposals, goodwill, and consolidation. ASU 2017-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those periods and is to be applied prospectively to transactions on or after the adoption date. The Company adopted ASU 2017-01 effective January 1, 2018, and the adoption will not have an impact on the Company's historical consolidated financial statements.


81

Table of Contents

In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718) ("ASU 2017-09"). ASU 2017-09 provides guidance on when changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. An entity should account for the effects of a modification unless all of the following are met:

| | |
| • | The fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified |
| | |
| • | The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified |
| | |
| • | The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. |

The amendments in ASU 2017-09 are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The amendments are to be applied prospectively to an award modified on or after the adoption date. The Company adopted ASU 2017-09 effective January 1, 2018, and the adoption will not have an impact on the Company's consolidated financial statements.

Standards Being Evaluated/Standards Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 amends the existing accounting standards for lease accounting by requiring entities to include substantially all leases on the balance sheet by requiring the recognition of right-of-use assets and lease liabilities for all leases. Entities may elect to not recognize leases with a maximum possible term of less than 12 months. For lessees, a lease is classified as finance or operating and the asset and liability are initially measured at the present value of the lease payments. For lessors, accounting for leases is largely unchanged from previous guidance. ASU 2016-02 also requires qualitative disclosures along with certain specific quantitative disclosures for both lessees and lessors. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, with early adoption permitted, and are effective for interim periods in the year of adoption. The ASU should be applied using a modified retrospective approach, which requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the amendments in this update, an entity should perform its annual or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. However, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 should be applied on a prospective basis and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements.
Contingencies
In the ordinary course of business, we may become party to lawsuits, administrative proceedings and governmental investigations, including regulatory and other matters. As of December 31, 2017 , management does not believe that any of our outstanding lawsuits, administrative proceedings or investigations could result in a material adverse effect.
Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated.

Emerging Growth Company Status
We are an "emerging growth company" within the meaning of the federal securities laws. For as long as we are an emerging growth company, we will not be required to comply with certain requirements that are applicable to other public companies that are not "emerging growth companies" including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, the reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and the exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. In addition, Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards, but we have irrevocably opted out of the extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.
We intend to take advantage of these exemptions until we are no longer an emerging growth company. We will cease to be an "emerging growth company" upon the earliest of: (i) the last day of the fiscal year in which we have $1.07 billion or more in annual revenues; (ii) the date on which we become a "large accelerated filer" (the fiscal year-end on which the total market value of our common equity securities held by non-affiliates is $700 million or more as of June 30); (iii) the date on which we issue more than $1.0 billion of non-convertible debt over a three-year period; or (iv) the last day of 2019.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risks relating to our operations result primarily from changes in commodity prices and interest rates, as well as counterparty credit risk. We employ established risk management policies and procedures to manage, measure, and limit our exposure to these risks.
Commodity Price Risk
We hedge and procure our energy requirements from various wholesale energy markets, including both physical and financial markets and through short and long-term contracts. Our financial results are largely dependent on the margin we are able to realize between the wholesale purchase price of natural gas and electricity plus related costs and the retail sales price we charge our customers for these commodities. We actively manage our commodity price risk by entering into various derivative or non-derivative instruments to hedge the variability in future cash flows from fixed-price forecasted sales and purchases of natural gas and electricity in connection with our retail energy operations. These instruments include forwards, futures, swaps, and option contracts traded on various exchanges, such as NYMEX and Intercontinental Exchange, or ICE, as well as over-the-counter markets. These contracts have varying terms and durations, which range from a few days to several years, depending on the instrument. We also utilize similar derivative contracts in connection with our asset optimization activities to attempt to generate incremental gross margin by effecting transactions in markets where we have a retail presence. Generally, any of such instruments that are entered into to support our retail electricity and natural gas business are categorized as having been entered into for non-trading purposes, and instruments entered into for any other purpose are categorized as having been entered into for trading purposes.
Our net loss on our
Our net gain on non-trading derivative instruments, net of cash settlements, was $29.2 million for the year ended December 31, 2018 .
We have adopted risk management policies to measure and limit market risk associated with our fixed-price portfolio and our hedging activities. For additional information regarding our commodity price risk and our risk management policies, see "Item 1A-Risk Factors."

We measure the commodity risk of our non-trading energy derivatives using a sensitivity analysis on our net open position. As of December 31, 2018 , our Gas Non-Trading Fixed Price Open Position (hedges net of retail load) was a short position of 391,416 MMBtu. An increase of 10% in the market prices (NYMEX) from their December 31, 2018 levels would have increased the fair market value of our net non-trading energy portfolio by $0.1 million . Likewise, a decrease of 10% in the market prices (NYMEX) from their December 31, 2018 levels would have decreased the fair market value of our non-trading energy derivatives by $0.1 million . As of December 31, 2018 , our Electricity Non-Trading Fixed Price Open Position (hedges net of retail load) was a long position of 48,125 MWhs. An increase of 10% in the forward market prices from their December 31, 2018 levels would have increased the fair market value of our net non-trading energy portfolio by $0.3 million . Likewise, a decrease of 10% in the forward market prices from their December 31, 2018 levels would have decreased the fair market value of our non-trading energy derivatives by $0.3 million .
Credit Risk
In many of the utility services territories where we conduct business, POR programs have been established, whereby the local regulated utility purchases our receivables, and becomes responsible for billing the customer and collecting payment from the customer. This service results in substantially all of our credit risk being with the utility and not to our end-use customer in these territories. Approximately 66% , 66% and 67% of our retail revenues were derived from territories in which substantially all of our credit risk was with local regulated utility companies as of December 31, 2018 , 2017 and 2016 , respectively, all of which had investment grade ratings as of such date. During the same period, we paid these local regulated utilities a weighted average discount of approximately 1.0% , 1.1% and 1.3% , respectively, of total revenues for customer credit risk protection. In certain of the POR markets in which we operate, the utilities limit their collections exposure by retaining the ability to transfer a delinquent account back to us for collection when collections are past due for a specified period.
If our collection efforts are unsuccessful, we return the account to the local regulated utility for termination of service. Under these service programs, we are exposed to credit risk related to payment for services rendered during

84

Table of Contents

the time between when the customer is transferred to us by the local regulated utility and the time we return the

Table of Contents

customer to the utility for termination of service, which is generally one to two billing periods. We may also realize a loss on fixed-price customers in this scenario due to the fact that we will have already fully hedged the customer's expected commodity usage for the life of the contract.
In non-POR markets (and in POR markets where we may choose to direct bill our customers), we manage customer credit risk through formal credit review in the case of commercial customers, and credit score screening, deposits and disconnection for non-payment, in the case of residential customers. Economic conditions may affect our customers' ability to pay bills in a timely manner, which could increase customer delinquencies and may lead to an increase in bad debt expense. Our bad debt expense for the year ended December 31, 2017 , 2016 and 2015 was approximately 2.5% , 0.6% and 5.0% 2018 , 2017 and 2016 was approximately 2.6% , 2.5% and 0.6% of non-POR market retail revenues, respectively. See "Management's Discussion and Analysis of Financial Condition and Results of Operations-Drivers of Our Business-Customer Credit Risk" for an analysis of our bad debt expense related to non-POR markets during 2018 .
We are exposed to wholesale counterparty credit risk in our retail and asset optimization activities. We manage this risk at a counterparty level and secure our exposure with collateral or guarantees when needed. At December 31, 2018 and 2017 , approximately $4.1 million and $5.3 million of our total exposure of $22.7 million and $34.2 million , respectively, was either with a non-investment grade counterparty or otherwise not secured with collateral or a guarantee. The credit worthiness of the remaining exposure with other customers was evaluated with no material allowance recorded at December 31, 2018 and 2017 .
Interest Rate Risk
We are exposed to fluctuations in interest rates under our variable-price debt obligations. At December 31, 2018 , we were co-borrowers under the Senior Credit Facility, under which $129.5 million of variable rate indebtedness was outstanding. Based on the average amount of our variable rate indebtedness outstanding during the year ended December 31, 2018 , a 1% percent increase in interest rates would have resulted in additional annual interest expense of approximately $1.3 million . During the year ended December 31, 2018 , we entered into two interest rate swap agreements to manage interest rate risk. we do not currently employ interest rate hedges, although we may choose to do so in the future.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

It is the responsibility of the management of Spark Energy, Inc. to establish and maintain adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended, as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

| | |
| • | Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of the assets; |
| | |
| • | Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and the receipts and expenditures are being made only in accordance with authorizations of our management and directors; and |
| | |
| • | Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our financial statements. |
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Management has assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2018 , utilizing the criteria in the Committee of Sponsoring Organizations of the Treadway Commission's Internal Control-Integrated Framework (2013) . Based on its assessment, our management concluded the Company's internal control over financial reporting was effective as of December 31, 2018 .

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2018, and the results of its consolidated operations and its cash flows for the year ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting as of December 31, 2017 . the business constituted 21% of the Company's total assets as of December 31, 2017 and 10% of the Company's consolidated revenues for the year ended December 31, 2017 .but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting.

An emerging growth company may take advantage of specified reduced reporting and other regulatory requirements.

stock upon an exchange of Class B common stock or Series A Preferred Stock), Spark HoldCo will concurrently issue a corresponding limited liability company unit either to The holder of the Class B common stock, or to the Company in the case of the issuance of shares of Class A common stock, Series A Preferred Stock or such other equity security. As a result, the number of Spark HoldCo units held by the Company always equals the number of shares of Class A common stock, Series A Preferred Stock or such other equity Securities of the Company outstanding.
The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Our financial statements are presented on a consolidated basis and include all wholly-owned and controlled subsidiaries. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. All significant intercompany transactions and balances have been eliminated in the consolidated financial statements.
Each share of Class B common stock, all of which are held by NuDevco Retail and Retailco, has no economic rights but entitles the holder to one vote on all matters to be voted on by stockholders generally. Holders of Class a common stock and Class B common stock vote together as a single class on all matters presented to our stockholders for their vote or approval, except as otherwise required by applicable law or by our certificate of incorporation.
NuDevco Retail and Retailco have the right to exchange (the "Exchange Right") all or a portion of their Spark HoldCo units (together with a corresponding number of shares of Class B common stock) for Class A common stock (or cash at Spark Energy, Inc.'s or Spark HoldCo's election (the "Cash Option")) at an exchange ratio of one share of Class a common stock for each Spark HoldCo unit (and corresponding share of Class B common stock) exchanged. In addition, NuDevco Retail and Retailco have the right, under certain circumstances, to cause The Company to register the offer and resale of NuDevco Retail's and Retailco's shares of Class A common stock obtained pursuant to the Exchange Right. Retail Acquisition Co., LLC ("RAC") was entitled to similar registration rights under the $2.1 million convertible subordinated note (the "CenStar Note") and $5.0 million convertible subordinated note (the "Oasis Note") prior to their respective conversions to Class B common stock in January 2017. Refer to Note 8 "Debt" for further information.


Immaterial Corrections to Prior Year Financial Information

The consolidated balance sheet, income statements, statement of changes in stockholders' equity and our cash flow statements reflect immaterial adjustments to the historical balances in additional paid in capital, non-controlling interest, deferred tax assets, retained earnings, income tax expense, net (loss) income attributable to non-controlling interest, and earnings per share for the years ended December 31, 2017 and 2016. We made these adjustments in accordance with GAAP, to reflect the amounts the owners of our Class A and Class B common stock would receive, respectively, if the assets of our subsidiary, Spark HoldCo, were sold, and its liabilities were settled at their recorded book values as of each balance sheet date. In addition, we adjusted income for the year ended December 31, 2017 to reflect the impact on income of the changes in deferred tax balances referenced above and to make certain immaterial corrections to the allocation of income between non-controlling interests and income available for common shareholders. Our adjustments had no impact on the manner in which distributions were paid in any current or prior period. The Company evaluated the materiality of the errors from quantitative and qualitative perspectives, and concluded that the errors were immaterial to the Company's prior period interim and annual consolidated financial statements. Since the revision was not material to any prior period interim or annual consolidated financial statements, no amendments to previously filed interim or annual periodic reports was



tax Receivable Agreement

The Company is party to a Tax Receivable Agreement with Spark HoldCo, NuDevco Retail Holdings and NuDevco Retail. This agreement generally provides for the payment by the Company to Retailco, LLC (as successor to NuDevco Retail Holdings) and NuDevco Retail of 85% of the net cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes (or is deemed to realize in certain circumstances) in future periods as a result of (i) any tax basis increases resulting from the purchase by the Company of Spark HoldCo units from NuDevco Retail Holdings, (ii) any tax basis increases resulting from the exchange of Spark HoldCo units for shares of Class A common stock pursuant to the Exchange Right (or resulting from an exchange of Spark HoldCo, units for cash pursuant to the Cash Option) and (iii) any imputed interest deemed to be paid by the Company as a result of and additional tax basis arising from, any payments the Company makes under the tax Receivable Agreement. The Company retains the benefit of the remaining 15% of these tax savings. See Note 12 "Income Taxes" for further discussion.
in certain circumstances, The Company may defer or partially defer any payment due (a "TRA Payment") to the holders of rights under the Tax Receivable Agreement, which are currently Retailco and NuDevco Retail. During the five -year period ending September 30, 2019, the Company will defer all or a portion of any TRA Payment owed pursuant to the Tax Receivable Agreement to the extent that Spark HoldCo does not generate sufficient Cash Available for Distribution (as defined below) during the four -quarter period ending September 30th of the applicable year in which the TRA Payment is to be made in an amount that equals or exceeds 130% (the "TRA Coverage Ratio") of the Total Distributions (as defined Below paid in such four-quarter period by Spark HoldCo. for purposes of computing the TRA Coverage Ratio:

In the event that the TRA Coverage Ratio is not satisfied in any calendar year, the Company will defer all or a portion of the TRA Payment to NuDevco Retail or Retailco under the Tax Receivable Agreement to the extent necessary to permit Spark HoldCo to satisfy the TRA Coverage Ratio (and Spark HoldCo is not required to make and will not make the pro rata distributions to its members with respect to the Deferred portion of the TRA Payment).

Following the five -year deferral period ending September 30, 2019, the Company will be obligated to pay any outstanding deferred TRA Payments to the extent such deferred TRA Payments do not exceed (i) the lesser of the Company's proportionate share of aggregate cash Available for Distribution of Spark HoldCo during the five -year deferral period or the cash distributions actually received by the Company during the five -year deferral period, reduced by (ii) the sum of (a) the aggregate target quarterly dividends (which, for the purposes of the Tax Receivable Agreement, will be $0.18125 per Class A common stock share and $0.546875 per Series A Preferred Stock share per quarter) during the five -year deferral period, (b) the Company's estimated taxes during the five -year deferral period, and (c) all prior TRA Payments and (d) if with respect to the quarterly period during which the deferred TRA Payment is otherwise paid or payable, Spark HoldCo has or reasonably determines it will have amounts necessary to cause the Company to receive distributions of Cash equal to the target quarterly distribution payable during that quarterly period. Any portion of the deferred TRA Payments not payable due to these limitations will no longer be payable.

See further discussion in the Recent Accounting Pronouncements section, below.


We met the threshold coverage ratio required to fund the second TRA Payment to Retailco and NuDevco Retail under the Tax Receivable Agreement during the four-quarter period ending September 30, 2016, resulting in an initial TRA Payment of $1.4 million becoming due in December 2016. On November 6, 2016, Retailco and NuDevco Retail granted the Company the right to defer the TRA Payment until May 2018. During the period of time when the Company has elected to defer the TRA Payment, the outstanding payment amount will accrue interest at a rate calculated In the manner provided for under the Tax Receivable Agreement. The initial payment of $1.4 million deferred until May 2018 was classified to a current liability as of December 31, 2017 .


In addition, immaterial adjustments have been made to certain December 31, 2015 equity balances, as noted in the table below.

Use of Estimates and Assumptions

The preparation of the Company's


the accompanying
consolidated financial statements requires estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the of the Company have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). the Company's consolidated financial statements are presented on a consolidated basis and include all wholly-owned and controlled subsidiaries. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. All significant intercompany transactions and balances have been eliminated in the consolidated financial statements.and the reported amounts of revenues and expenses during the period. Actual results could materially differ from those estimates.

Relationship with our Founder and Majority Shareholder

W. Keith Maxwell, III (our "Founder") is the owner of a majority of the voting power of our common stock through his ownership of NuDevco Retail, LLC ("NuDevco Retail") and Retailco, LLC ("Retailco"). Retailco is a wholly owned subsidiary of TxEx Energy Investments, LLC ("TxEx"), which is wholly owned by Mr. Maxwell. NuDevco Retail is a wholly owned subsidiary of NuDevco Retail Holdings LLC ("NuDevco Retail Holdings"), which is a wholly owned subsidiary of Electric HoldCo, LLC, which is also a wholly owned subsidiary of TxEx.
We enter into transactions with and pay certain costs on behalf of affiliates that are commonly controlled by Mr. Maxwell, and these affiliates enter into transactions with and pay certain costs on our behalf. We undertake these transactions in order to reduce risk, reduce administrative expense, create economies of scale, create strategic alliances and supply goods and services among these related parties.
These transactions include, but are not limited to, certain services to the affiliated companies associated with employee benefits provided through the Company's benefit plans, insurance plans, leased office space, certain administrative salaries, for management due diligence, work, recurring management consulting, and accounting, tax, legal, or technology services. Amounts billed under these arrangements are based on services provided, departmental usage, or headcount, which are considered reasonable by management. As such, the accompanying consolidated financial statements include costs that have been incurred by the Company and then directly billed or allocated to affiliates, and costs that have been incurred by our affiliates and then directly billed or allocated to us, and are recorded net in general and administrative expense on the consolidated statements of operations with a corresponding accounts receivable-affiliates or accounts payable-affiliates, respectively, recorded in the consolidated balance sheets. Additionally, the Company enters into transactions with certain affiliates for sales or purchases of natural gas and electricity, which are recorded in retail revenues, retail cost of revenues, and net asset optimization revenues in the consolidated statements of operations with a corresponding accounts receivable-affiliate or accounts payable-affiliate in the consolidated balance sheets. The allocations and related estimates and assumptions are described more fully in Note 15 "Transactions with Affiliates."

Cash and Cash Equivalents

Cash and cash equivalents consist of all unrestricted demand deposits and funds invested in highly liquid instruments with original maturities of three months or less. The Company periodically assesses the financial

77

Table of Contents

condition of the institutions where these funds are held and believes that its credit risk is minimal with respect to these institutions.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest.Accounts receivable in the consolidated balance sheets are net of allowance for doubtful accounts of $4.0 million and $2.3 million as of December 31, 2017 and 2016 , respectively.

The Company accrues an allowance for doubtful accounts based upon estimated uncollectible accounts receivable considering historical collections, accounts receivable aging analysis, credit risk and other factors. The Company writes off accounts receivable balances against the allowance for doubtful accounts when the accounts receivable is deemed to be uncollectible. Bad debt expense of $10.1 million , $6.6 million and $1.3 million was recorded in general and administrative expense in the consolidated statements of operations for the years ended December 31, 2018 , 2017 and 2016 , respectively.

The Company conducts business in many utility service markets where the local regulated utility purchases our receivables, and then becomes responsible for billing the customer and collecting payment from the customer ("POR programs"). This POR service results in substantially all of the Company's credit risk being linked to the applicable utility, which generally has an investment-grade rating, and not to the end-use customer. The Company monitors the financial condition of each utility and currently believes that its susceptibility to an individually significant write-off as a result of concentrations of customer accounts receivable with those utilities is remote. such amounts are collectible. Trade accounts receivable that are part of a local regulated utility's POR program are recorded on a gross basis in accounts receivable in the consolidated balance sheets. The discount paid to the local regulated utilities is recorded in general and administrative expense in the consolidated statements of operations.

In markets that do not offer POR services or when the Company chooses to directly bill its customers, certain receivables are billed and collected by the Company. The Company bears the credit risk on these accounts and records an appropriate allowance for doubtful accounts to reflect any losses due to non-payment by customers. The

100

Table of Contents

Company's customers are individually insignificant and geographically dispersed in these markets. The Company writes off customer balances when it believes that amounts are no longer collectible and when it has exhausted all means to collect these receivables.

Inventory

Inventory consists of natural gas used to fulfill and manage seasonality for fixed and variable-price retail customer load requirements and is valued at the lower of weighted average cost or market. Purchased natural gas costs are recognized in the consolidated statements of operations, within retail cost of revenues, when the natural gas is sold and delivered out of the storage facility There were no inventory impairments recorded for the years ended December 31, 2017 , 2016 and 2015 . When natural gas is sold costs are recognized in the consolidated statements of operations, within retail cost of revenues, at the weighted average cost value at the time of the sale.using the weighted average cost of the gas sold.

Customer Acquisition Costs

The Company has retail natural gas and electricity customer acquisition costs net of $22.1 million and $18.8 million recorded in current assets, and $6.9 million and $6.1 million recorded in noncurrent assets. representing direct response advertising costs as of December 31,
The Company capitalizes direct response advertising costs that consist primarily of hourly and commission-based telemarketing costs, door-to-door agent commissions and other direct advertising costs associated with proven customer generation in its balance sheet. These costs are amortized over the estimated life of a customer.

As of December 31, 2018 and 2017 , the net customer acquisition costs were $18.3 million and $29.0 million , of which $14.4 million and $22.1 million were recorded in current assets, and $3.9 million and $6.9 million were recorded in non-current assets. Amortization of customer acquisition costs were $24.4 million , $21.4 million , and $17.5 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. Customer acquisition costs are spending for organic customer acquisitions and do not include customer acquisitions through merger and acquisition activities, which are recorded as customer relationships.Amortization of customer acquisition costs, recorded in depreciation and amortization in the consolidated statements of operations, was $21.4 million , $17.5 million and $18.0 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Capitalized direct response advertising costs consist primarily of hourly and commission based telemarketing costs, door-to-door agent commissions and other direct advertising costs associated with proven customer generation, and are capitalized and amortized over the estimated two -year average life of a customer in accordance with the provisions of FASB ASC 340-20, Capitalized Advertising Costs .

Recoverability of customer acquisition costs is evaluated based on a comparison of the carrying amount of such costs to the future net cash flows expected to be generated by the customers acquired, considering specific

78

Table of Contents

assumptions for customer attrition, per unit gross profit, and operating costs. These assumptions are based on forecasts and historical experience.

Customer Relationships

Customer acquisitions through direct acquisitions of customer contracts or recorded as part of the acquisition method in accordance with FASB ASC Topic 805, Business Combinations ("ASC 805") are recorded as customer relationships and represent customer contract acquisitions not acquired through The direct response advertising discussed above at " customer Acquisition Costs. " The Company has recorded $18.7 million and $12.1 Customer contracts recorded as part of mergers or acquisitions are reflected as customer relationships in our balance sheet. The Company had capitalized customer relationship of $16.6 million and $18.7 million , net of amortization, as current assets as of December 31, 2018 and 2017 , respectively, and $26.4 million and $34.8 million , net of amortization, as non-current assets as of December 31, 2018 and 2017 , respectively, related to these intangible assets. These intangibles are amortized on a straight-line basis over the estimated average life of the related customer contracts acquired, which ranges from three years to six years .

The acquired customer relationships intangibles related to Oasis, CenStar, Provider Companies, Major Energy Companies, Perigee Energy LLC, and Verde Companies, and HIKO are reflective of the acquired companies' customer base, and were valued at the respective dates of acquisition using an excess earnings method under the income approach. Using this method, the Company estimated the future cash flows resulting from the existing customer relationships, considering attrition as well as charges for contributory assets, such as net working capital, fixed assets, and assembled workforce. These future cash flows were then discounted using an appropriate risk-adjusted rate of return by retail unit to arrive at the present value of the expected future cash flows. CenStar, Oasis, Perigee, and HIKO customer relationships are amortized to depreciation and amortization based on the expected future net cash flows by year. The acquired customer relationship intangibles related to the Major Energy Companies, the Provider Companies and the Verde Companies were bifurcated between hedged and unhedged and amortized to depreciation

and amortization based on the expected future cash flows by year and expensed to retail cost of revenue based on the expected term of the underlying fixed price contract in each reporting period, respectively.
Customer relationship amortization expense was $20.3 million , $17.8 million , and $28.6 amortization expense was $17.8 million , $28.6 million , and $5.7 million for the years ended December 31, 2018 , 2017 and 2016 , respectively, of which approximately $(1.2) million , $0.3 million , and $15.8 million 2017 , 2016 and 2015 , respectively, approximately $0.3 million , $15.8 million , and zero of the $17.8 million , $28.6 million , and $5.7 million customer relationships amortization expense for the twelve months ending December 31, 2017 , 2016 , and 2015 , respectively, was included in retail cost of revenue for those years.

We review customer relationships for impairment whenever events or changes in business circumstances indicate the carrying value of the intangible assets may not be recoverable. Impairment is indicated when the undiscounted cash flows estimated to be generated by the intangible assets are less than their respective carrying value. If an impairment exists, a loss is recognized for the difference between the fair value and carrying value of the intangible assets.

No impairments of customer relationships were recorded for the years ended December 31, 2018 , 2017 and 2016 .

Non-compete agreements

We capitalize intangible costs associated with non-compete agreements in certain of our acquisitions. Non-compete agreements provide the Company with a certain level of assurance that acquired companies' expected earnings streams will not be disrupted by competition from the companies' previous owners or members. These non-compete agreements are amortized over their estimated useful life of three years on a straight-line basis. As of December 31, 2018 , the Company had $0.3 million of capitalized costs related to these non-compete agreements, of which $0.3 million was current, and of which zero was non-current. As of December 31, 2017 , the Company had $1.4 million of capitalized costs related to non-compete agreements, of which $1.1 million was current, and of which $0.3 million was non-current. Amortization expense was $1.1 million ,members. The fair values of non-compete agreements are determined using the differential valuation approach at acquisition date. Under this approach, the Company estimates the present value of expected future cash flows under two scenarios; one scenario assumes the non-compete agreements, are in place and the other scenario assumes the absence of non-compete agreements. The resulting difference between the two scenarios is the implied value of the non-compete agreements, which is further adjusted by an estimated probability factor representing the likelihood that previous members of acquired companies would be successful competitors.

As a result of the Provider Companies and Major Energy Companies acquisitions, the Company recorded $1.2 million , net of amortization, as Acquired customer intangibles - current, and $1.4 million , net of amortization, as Acquired customer intangibles - non-current. As of December 31, 2016 related to these non-compete agreements, These non-compete agreements are amortized over their estimated three -year life on a straight-line basis. Amortization expense was $1.2 million and $0.9 million for the years ended December 31, 2018 , 2017 and 2016 .

Trademarks

We record trademarks as part of our acquisitions which trademarks recorded as part of the acquisition method in accordance with ASC 805 represent the value associated with the recognition and positive reputation of an acquired company to its target markets. This value would otherwise have to be internally developed through significant time and expense or by paying a third party for its use. These intangibles are amortized over the estimated five -year to ten -year life of the trademark on a straight-line basis. The fair values of

79

Table of Contents

trademark assets were determined at the date of acquisition using a royalty savings method under the income approach. Under this approach, the Company estimates the present value of expected cash flows resulting from avoiding royalty payments to use a third party trademark. The Company analyzes market royalty rates charged for licensing trademarks and applied an expected royalty rate to a forecast of estimated revenue, which was then discounted using an appropriate risk adjusted rate of return.

The Company has recorded $8.6 million and $6.3 million , net of amortization, as other assets As of December 31, 2017 and 2016 As of December 31, 2018 and 2017 , we had recorded $7.3 million and $8.6 million related to these trademarks in other assets. These intangibles are amortized over the estimated five -year to twenty -year life of the trademarks on a straight-line basis. Amortization expense was $1.3 million , $0.8 million and $0.4 million for the years ended December 31, 2018 , 2017 and 2016 , respectively.

We review trademarks for impairment whenever events or changes in business circumstances indicate the carrying value of the intangible assets may not be recoverable. Impairment is indicated when the undiscounted cash flows estimated to be generated by the intangible assets are less than their respective carrying value. If an impairment exists, a loss is recognized for the difference between the fair value and carrying value of the intangible assets.

No impairments of trademarks were recorded for the years ended December 31, 2018 , 2017 and 2016 .

Deferred Financing Costs

Costs incurred in connection with the issuance of long-term debt are capitalized and amortized to interest expense using the straight-line method over the life of the related long-term debt. due to the variable nature of the Company's long-term debt.These costs are included in other assets in our consolidated balance sheets.

Property and Equipment

The Company records property and equipment at historical cost. Depreciation expense is recorded on a straight-line method based on estimated useful lives, When assets are placed into service, management makes estimates with respect to useful lives and salvage values of the assets.
which range from 2 to 5 years, along with estimates of the salvage values of the assets.
When items of property and equipment are sold or otherwise disposed of, any gain or loss is recorded in the consolidated statements of operations.

The Company capitalizes costs associated with certain of its internal-use software projects. Costs capitalized are those internal-use software projects. in accordance with FASB ASC Topic 350-40, Internal-Use Software . Capitalized Costs are the costs incurred during the application development stage of projects such as software configuration, coding, installation of hardware and testing. Costs incurred during the preliminary or post-implementation stage of the internal-use software project are expensed in the period incurred, including costs associated with formulation of ideas and alternatives, training and application maintenance. After internal-use software projects are completed, the associated capitalized costs are depreciated over the estimated useful life of the related asset. Interest costs incurred while developing internal-use software projects are also capitalized.capitalized. in accordance with FASB ASC Topic 835-20, Capitalization of Interest . Capitalized interest costs for the years ended December 31, 2018 , 2017 and 2016 were not material.

Goodwill

Goodwill represents the excess of cost over fair value of the assets of businesses acquired in accordance with FASB ASC Topic 350 Intangibles-Goodwill and Other ("ASC 350"). The goodwill on our consolidated balance sheet as of December 31, 2018 is associated with both our Retail Natural Gas and Retail Electricity reporting units. We determine our reporting units segments. We determine our segments, which are also considered our reporting unit, by identifying each unit that engaged in business activities from which it may earn revenues and incur expenses, had operating results regularly reviewed by the segment manager for purposes of resource allocation and performance assessment, and had discrete financial information.

Goodwill is not amortized, but rather is assessed for impairment whenever events or circumstances indicate that impairment of the carrying value of goodwill is likely, but no less often than annually as of October 31. On October 31, 2017, We elected to by-pass the option to perform a qualitative assessment of goodwill and performed a quantitative assessment of goodwill in accordance with guidance from ASC 350. This guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. If we fail the qualitative test or if we elect to by-pass the qualitative assessment, then we must We compare our estimate of the fair value of the reporting unit with its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, we perform the second step of the goodwill impairment test to measure the amount of goodwill impairment loss to be recorded, as necessary. The second step compares compare the implied fair value of the reporting unit's goodwill to the carrying value, if any, of that goodwill, We determine the implied fair value of the goodwill in the same manner as determining the amount of goodwill to be recognized in a business combination. the inputs used In the determination of fair value are generally level 3 inputs. See Note 9 "Fair Value Measurements" for further discussion. the difference of which is recorded as an impairment in the financial statements. In accordance with our accounting policy,

and the test indicated no impairment.

Treasury Stock

Treasury stock consists of Company's own stock that has been issued, but is subsequently reacquired by the Company. Treasury stock does not reduce the number of shares issued but does reduce the number of shares outstanding. These shares are not eligible to receive cash dividends. Accounting for treasury stock transactions is governed by FASB ASC Topic 550-30 Equity-Treasury Stock.

We use the cost method to account for treasury shares.Purchases of shares of Class A common stock are recorded at cost, and the gross cost of the Class A common stock purchased is charged to a contra equity account entitled "Treasury Stock."

Equity Method Investments

The Company accounts for investments in unconsolidated entities using the equity method of accounting as prescribed in FASB ASC Topic 323-10, Investments-Equity Method and Joint Venture, if the investment gives us We use the equity method of accounting to account for investments where we have the ability to exercise significant influence over, but not control, of an investee. Significant influence generally exists if we have an ownership interest representing between 20% and 50% of the voting stock of the investee. Under the equity method of accounting, investments are stated at initial cost and are adjusted for subsequent additional investments and our proportionate share of earnings or losses and distributions. Equity investments are presented on the consolidated balance sheet under "Other assets" and our share of their income is reflected as "Interest and other income" on the consolidated statements of operations. We determine our equity investment earnings using the Hypothetical Liquidation at Book Value (HLBV) method. Under the HLBV method, a calculation is prepared at each balance sheet date to determine the amount the Company would receive if the investee were to liquidate all of its assets, as valued in accordance with U.S. GAAP, and distribute that cash to the investors. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is the Company's share of the earnings or losses from the equity investment for the period. See Note 17 "Equity Method Investment" for further discussion.

Segment Reporting

The FASB ASC Topic 280, Segment Reporting , established standards for entities to report information about the operating segments and geographic areas in which they operate. The Company operates two segments, retail natural gas and retail electricity, and all of its operations are located in the United States.

Revenues and Cost of Revenues

Our revenues are derived primarily from the sale of natural gas and electricity to retail customers, The Company also records revenue from sales of natural gas and electricity to wholesale counterparties,customers, including affiliates. Revenues are recognized by the Company when: (1) persuasive evidence of an exchange arrangement exists, (2) delivery has occurred or services have been rendered, (3) the buyer's price is fixed or determinable and (4) collection is reasonably assured. Utilizing these criteria, revenue is recognized when the natural gas or electricity is delivered to the customer. Similarly, cost of revenues is recognized when the commodity is delivered.

Revenues for natural gas and electricity sales are recognized upon delivery under the accrual method. Natural gas and electricity sales that have been delivered but not billed by period end are estimated. Accrued unbilled revenues are based on estimates of customer usage since the date of the last meter read provided by the utility. Volume estimates are based on forecasted volumes and estimated customer usage by class. Unbilled revenues are calculated by multiplying these volume estimates by the applicable rate by customer class. Estimated amounts are adjusted when actual usage is known and billed.

Table of Contents

The Company records gross receipts taxes on a gross basis in retail revenues and retail cost of revenues. During the years ended December 31, 2017 , 2016 and 2015 , the Company's retail revenues and retail cost of revenues included gross receipts taxes of $9.0 million , $5.3 million and $3.0 million , respectively.

Costs for natural gas and electricity sales are similarly recognized recognized as the commodity is delivered to the customer under the accrual method. Natural gas and electricity costs that have not been billed to the Company by suppliers but have been incurred by period end are estimated. The Company estimates volumes for natural gas and electricity delivered based on the forecasted revenue volumes, estimated transportation cost volumes and estimation of other costs associated with retail load that varies by commodity utility territory. These costs include items like ISO fees, ancillary services and renewable energy credits. Estimated amounts are adjusted when actual usage is known and billed.

Our asset optimization activities, which primarily include natural gas physical arbitrage and other short term storage and transportation transactions, meet the definition of trading activities and are recorded on a net basis in the consolidated statements of operations in net asset optimization revenues. pursuant to FASB ASC Topic 815, Derivatives and Hedging . The Company recorded asset optimization revenues, primarily related to physical sales or purchases of commodities, of $178.3 million , $133.0 million and $154.1 $113.7 million , $178.3 million and $133.0 million for the years ended December 31, 2018 , 2017 and 2016 , respectively, and recorded asset optimization costs of revenues of $179.0 million , $133.6 million and $152.6 $109.2 million , $179.0 million and $133.6 million for the years ended December 31, 2018 , 2017 and 2016 , respectively, which are presented on a net basis in asset optimization revenues.

Natural Gas Imbalances

The consolidated balance sheets include natural gas imbalance receivables and payables, which primarily result when customers consume more or less gas than has been delivered by the Company to local distribution companies ("LDCs"). The settlement of natural gas imbalances varies by LDC, but typically the natural gas imbalances are settled in cash or in kind on a monthly, quarterly, semi-annual or annual basis. The imbalances are valued at their estimated net realizable value. The Company recorded an imbalance receivable of $0.8 million and $0.7 million in other current assets on the consolidated balance sheets as of December 31, 2018 and 2017 , respectively. The Company recorded an imbalance payable of $0.3 million and $1.0 million in other current liabilities on the consolidated balance sheets as of December 31, 2018 and 2017 , respectively.

Fair Value

FASB ASC Topic 820, Fair Value Measurement , established a single authoritative definition of fair value, set out a framework for measuring fair value, and requires disclosures about fair value measurements. The standard clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The standard utilizes a fair value hierarchy that prioritizes the inputs to the valuation techniques used to measure fair value into three broad levels based on quoted prices in active market, observable market prices, and unobservable market prices.

When the Company is required to measure fair value, and there is not a quoted or observable market price for a similar asset or liability, the Company utilizes the cost, income, or market valuation approach depending on the quality of information available to support management's assumptions.

Derivative Instruments

The Company uses derivative instruments such as futures, swaps, forwards and options to manage the commodity price risks of its business operations.

All derivatives other than those for which an exception applies, are recorded in the consolidated balance sheets at fair value. Derivative instruments representing unrealized gains are reported as derivative assets while derivative instruments representing unrealized losses are reported as derivative liabilities. The Company has elected to offset
We offset

Table of Contents

amounts in the consolidated balance sheets for derivative instruments executed with the same counterparty under a master netting arrangement.One of the exceptions to fair value accounting, normal purchases and normal sales, has been elected by the Company for certain derivative instruments when the contract satisfies certain criteria, including a requirement that physical delivery of the underlying commodity is probable and is expected to be used in normal course of business. Retail revenues and retail cost of revenues resulting from deliveries of commodities under normal purchase contracts and normal sales contracts are included in earnings at the time of contract settlement.where we have a master netting arrangement.

As part of our asset optimization activities, we manage a portfolio of commodity derivative instruments held for trading purposes. Changes in fair value of and amounts realized upon settlements of derivatives instruments held for trading purposes are recognized in earnings in net asset optimization revenues.

To manage commodity price risk, the Company holds certain To manage the retail business, the Company holds derivative instruments that are not held for trading purposes and are not designated as hedges for accounting purposes. However, to the extent the Company does not hold offsetting positions for such derivatives, they believe these instruments represent economic hedges that mitigate their exposure to fluctuations in commodity prices. As part of the Company's strategy to optimize its assets and manage related commodity risks, it also manages a portfolio of commodity derivative instruments held for trading purposes. The Company uses established policies and procedures to manage the risks associated with price fluctuations in these energy commodities and uses derivative instruments to reduce risk by generally creating offsetting market positions.

Changes in the fair value of and amounts realized upon settlement of derivative instruments not held for trading purposes are recognized currently in retail costs of revenues.

Changes in the fair value of and amounts realized upon settlement of derivative instruments held for trading purposes are recognized currently in earnings in net asset optimization revenues.

Income Taxes

The Company recognizes the amount of taxes payable or refundable for the year. In addition, the Company follows the asset and liability method of accounting for income taxes where deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in the financial statements or tax returns and operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in those years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in the tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for deferred tax assets if it is more likely than not that these items will not be realized. Amounts owed or refundable on current year returns is included as a current payable or receivable in the consolidated balance sheet.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the projected future taxable income and tax planning strategies in making this assessment.Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that we will realize the benefits of these deductible differences.

The Company recognizes interest and penalties related to unrecognized tax benefits within the provision for income taxes on continuing operations in our consolidated statements of operations.

Earnings per Share

Basic earnings per share ("EPS") is computed by dividing net income attributable to shareholders (the numerator) by the weighted-average number of Class A common shares outstanding for the period (the denominator). Class B

common shares are not included in the calculation of basic earnings per share because they are not participating securities and have no economic interest in us. Diluted earnings per share is similarly calculated except that the denominator is increased for potentially dilutive securities.

The weighted average ownership percentages for the applicable reporting period are used to allocate the remaining income (loss) before income taxes to the each economic interest owner.

Commitments and Contingencies

The Company enters into various firm purchase and sale commitments for natural gas, storage, transportation, and electricity that do not meet the definition of a derivative instrument. Management does not anticipate that such commitments will result in any significant gains or losses based on current market conditions.

Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.

Use of Estimates and Assumptions

The preparation of the Company's consolidated financial statements requires estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Actual results could materially differ from those estimates. Significant items subject to such estimates by the Company's management include estimates for unbilled revenues and related cost of revenues, provisions for uncollectible receivables, valuation of customer acquisition costs, estimated useful lives of property and equipment, valuation of derivatives and reserves for contingencies.

Recent Accounting Pronouncements

Adopted Standards

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) ("ASU 2016-09"). ASU 2016-09 includes provisions intended to simplify various aspects of accounting for shared-based payments, including income tax consequences, classification of awards as either equity or liability and classification on the statement of cash flows. This guidance is effective for annual and interim reporting periods of public entities beginning after December 15, 2016. The Company adopted ASU 2016-09 On January 1, 2017.
On January 1, 2018, we adopted ASU


The new standard requires prospective recognition of excess tax benefits resulting from stock-based compensation vesting and exercises to be recognized as a reduction of income taxes and reflected in operating cash flows. Previously, these amounts were recognized in additional paid-in capital and presented as a financing activity on the statement of cash flows. Net excess tax benefits of $0.2 million were recognized as a reduction of income taxes for the year ended December 31, 2017 . Prior periods have not been adjusted.

The Company has elected to continue to estimate the number of stock-based awards expected to vest, as permitted by ASU 2016-09, rather than electing to account for forfeitures as they occur.

ASU 2016-09 requires that employee taxes paid when an employer withholds shares for tax-withholding purposes to be reported as financing activities in the statement of cash flows. Previously, these cash flows were included in operating activities. The Company has elected to adopt this prospectively, as permitted by ASU 2016-09. This change resulted in a $1.1 million impact on the statement of cash flow for the year ended December 31, 2017 .

In October 2016, the FASB issued ASU No. 2016-17, Consolidation (Topic 810): Interests Held through Related Parties that Are under Common Control ("ASU 2016-17"). ASU 2016-17 amends the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity ("VIE") should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. Under ASU 2016-17, a single decision maker of a VIE is required to consider indirect economic interests in the entity held through related parties on a proportionate basis when determining whether it is the primary beneficiary of that VIE. If a single decision maker and its related party are under common control, the single decision maker is required to consider indirect interests in the entity held through those related parties to be the equivalent of direct interests in their entirety. The amendments are effective for public business entities for fiscal years beginning after December 15, 2016 (the Company's first quarter of fiscal 2017), including interim periods within those fiscal years. The standard is to be applied retrospectively or through a cumulative effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company adopted ASU 2016-17 effective January 1, 2017, and the adoption had no impact on the Company's consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"). ASU 2016-18 is intended to add and clarify guidance on the classification and presentation of restricted cash on the statement of cash flows. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents

should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted ASU 2016-18 effective April 1, 2017, and has included restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.

Standards adopted in 2018

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard permits the use of either the retrospective or cumulative effect transition method. In December 2016, the FASB further issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers , to increase stakeholders' awareness of the proposals and to expedite improvements to ASU 2014-09.

The FASB issued additional amendments to ASU No. 2014-09, as amended by ASU No. 2015-14:

| | |
| • | March 2016 - ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) ("ASU 2016-08").

The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to customers. |

| | |
| • | April 2016 - ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ("ASU 2016-10"). ASU 2016-10 covers two specific topics: performance obligations and licensing. This amendment includes guidance on immaterial promised goods or services, shipping or handling activities, separately identifiable performance obligations, functional or symbolic intellectual property licenses, sales-based and usage-based royalties, license restrictions (time, use, geographical) and licensing renewals. |

| | |
| • | May 2016 - ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and Practical Expedients ("ASU 2016-12"). ASU 2016-12 clarifies certain core recognition principles including collectability, sales tax presentation, noncash consideration, contract modifications and completed contracts at transition and disclosures no longer required if the full retrospective transition method is adopted. |

| | |
| • | September 2017 - ASU No. 2017-13, Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments ("ASU 2017-13"). ASU 2017-13 provides additional implementation guidance related to ASC Topic 606 and is effective for annual reporting periods beginning after December 15, 2017. |

| | |
| • | November 2017 - ASU No. 2017-14, Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 116 and SEC Release No. 33-10403 ("ASU 2017-14"). ASU 2017-14 amends various paragraphs in ASC 605, Revenue Recognition ; and ASC 606, Revenue from Contracts With Customers , that contain SEC guidance. The amendments include superseding ASC 605-10-S25-1 (SAB Topic 13) as a result of SEC Staff Accounting Bulletin No. 116 and adding ASC 606-10-S25-1 as a result of SEC Release No. 33-10403. |

In 2017, We collaborated with an external professional services firm to analyze the impact of the standard on our contract portfolio by reviewing our current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to our revenue contracts. In addition, we identified and implemented appropriate changes to our business processes, systems and controls to support recognition and disclosure under the new standard.
We adopted the standard

Table of Contents

The Company adopted the new standard effective January 1, 2018 utilizing the full retrospective approach, and the adoption of the new standard will result in an immaterial impact to had no impact on our total revenues and operating income for the years ended December 31, 2018, 2017 and 2016. 2017 and 2016. since our contracts with customers identify the delivery of products and services that are individually distinct performance obligations and revenue is recognized when performance obligations are satisfied. As a result, receivable balances related to revenue, including amounts related to unbilled revenue, are reflected as accounts receivable in the consolidated balance sheets. No other revenue related contract assets or liabilities are recorded.

The standard requires expanded disclosures regarding the qualitative and quantitative information of an entity's nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

Note the Company's asset optimization activities meet the definition of trading activities per FASB ASC Topic 815, Derivatives and Hedging, and are therefore excluded from the scope of Revenue from Contracts with Customers (Topic 606) .

See Note 3 "Revenues" for further disclosure.

On January 1, 2018, we adopted ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business ("ASU 2017-01"). ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. We utilized ASU 2017-01 in evaluating all acquisitions occurring after the date of adoption.


in August 2016, the FASB issued



On January 1, 2018, we adopted ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). ASU 2016-15 provides guidance on the presentation and classification of eight specific cash flow issues in the statement of cash flows, Those issues are cash payment for debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instrument or other debt instrument with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; including contingent consideration payments made after a business combination. cash proceeds from the settlement of insurance claims, cash received from settlement of corporate-owned life insurance policies; distribution received from equity method investees; beneficial interest in securitization transactions; and classification of cash receipts and payments that have aspects of more than one class of cash flows. The guidance is effective for interim and annual reporting periods beginning after December 15, 2017. This ASU is to be applied We applied this guidance using a retrospective transition method for each period presented. The Company adopted ASU 2016-15 effective January 1, 2018 and will classify contingent consideration payments made after a business combination as cash outflows for operating and financing activities on a retrospective basis. Because of the change in accounting guidance, we reclassified acquisition related payments of approximately $1.8 million and $0.8 million from cash flows from investing activities to cash flows from operating activities for the years ended December 31, 2017 and December 31, 2016, respectively. We reclassified acquisition related payments of approximately $18.4 million and $2.0 million from cash flows from investing activities to cash flows from financing activities for the years ended December 31, 2017 and December 31, 2016, respectively.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory ("ASU 2016-16"), ASU 2016-16 requires immediate recognition of the current and deferred income tax consequences of intercompany asset transfers other than inventory Current U.S. GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until which states an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and not when the asset has been sold to an outside party. The amendments in this guidance eliminate exceptions for intra-entity transfer of an asset, such as intellectual property and property, plant, and equipment. ASU 2016-16 is effective on this guidance is effective for annual and interim reporting periods of public entities beginning after December 15, 2017. This ASU is to be applied using a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption.

Standards Being Evaluated/Standards not yet adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 amends the existing accounting standards for lease accounting by requiring entities to include substantially all leases on the balance sheet by requiring the recognition of right-of-use assets and lease liabilities for all leases Entities may elect to not recognize leases with a maximum possible term of less than 12 months. For lessees, a lease is classified as finance or operating and The asset and liability are initially measured at the present value of the lease payments. For lessors, accounting for leases is largely unchanged from previous guidance ASU 2016-02 also Under this new guidance, lessees will be required to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of greater than twelve months. The guidance requires qualitative disclosures along with certain specific quantitative disclosures for both lessees and lessors. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842 , Leases ("ASU 2018-10"), and ASU No. 2018-11, Leases (Topic 842): Targeted Improvements ("ASU 2018-11"), to provide additional guidance for the adoption of Topic 842. The ASU and its related amendments are effective for fiscal years beginning after December 15, 2018, with early adoption permitted, and are effective for interim periods in the year of adoption. The ASU should be applied using a modified retrospective approach, which requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements.with an option to use certain practical expedients, which we expect to use. We have evaluated the impact of this new guidance and reviewed lease or possible lease contracts and evaluated contract related processes. We believe the primary impact will be related to the recognition of right-of-use assets and liabilities for our real estate operating leases in the range of approximately $1.0 million to $1.5 million .

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the amendments in this update, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, including goodwill. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. However, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 should be applied on a prospective basis and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted ASU 2017-04 effective January 1, 2019, and the adoption of this standard did not have a material impact on the Company's consolidated financial statements. the Company is currently evaluating the impact of adopting this guidance on its

Retail Electricity

Revenues for electricity sales are recognized under the accrual method when our performance obligation to a customer is satisfied, which is the point in time when the product is delivered and control of the product passes to the customer. Electricity products may be sold as fixed or variable rate products. The typical length of a contract to provide electricity is 12 months. Customers are billed and typically pay at least monthly, based on usage. Electricity sales that have been delivered but not billed by period end are estimated. Accrued unbilled revenues are based on estimates of customer usage since the date of the last meter read provided by the utility. Volume estimates are based on forecasted volumes and estimated residential and commercial customer usage. Unbilled revenues are calculated by multiplying these volume estimates by the applicable rate by customer class (residential or commercial). Estimated amounts are adjusted when actual usage is known and billed.


the Company's consolidated statements of operations for The year ended December 31, 2015 included $21.4 million of revenue and a $1.4 million loss on operations of CenStar. the Company incurred $0.1 million of acquisition related costs for the year ended December 31, 2015, in connection with the acquisition of CenStar, which have been expensed as incurred and included in general and administrative expense in the consolidated statement of operations.

The acquired customer relationships intangibles related to Perigee are reflective of Perigee's customer base, and were valued at the respective dates of acquisition using an excess earnings method under the income approach. Using this method, the Company estimated the future cash flows resulting from the existing customer relationships, considering attrition as well as charges for contributory assets, such as net working capital, fixed assets, and assembled workforce. These future cash flows were then discounted using an appropriate risk-adjusted rate of return by retail unit to arrive at the present value of the expected future cash flows. These customer relationships are amortized to depreciation and amortization based on the expected future net cash flows by year.

Acquisition of HIKO
In March 2018, we entered into a Membership Interest Purchase Agreement under which we acquired all of the membership interests of HIKO Energy, LLC ("HIKO"), a New York limited liability company, for a total purchase price of $6.0 million in cash, plus working capital. At the time of acquisition, HIKO had a total of approximately 29,000 RCEs located in 42 markets in seven states. The acquisition was accounted for under the acquisition method.

Our condensed consolidated statements of operations for the twelve months ended December 31, 2018 included $15.3 million of revenue and $3.8 million of net income related to the operations of HIKO.

In each of our acquisitions, we evaluate and allocate purchase price based on the following general assumptions.


Customer relationships.

The Acquired customer relationships intangibles related to the Verde Companies are reflective of the Verde were reflective of the acquired companies' customer bases, and were valued using an excess earnings method under the income approach. Using this method, we estimated the future cash flows resulting from the existing customer relationships, considering estimated attrition as well as charges for contributory assets, such as net working capital, intangible assets, fixed assets, and any assembled workforce. These future cash flows were then discounted using an appropriate risk-adjusted rate of return to arrive at the present value of the expected future cash flows.These

In acquisitions where we acquired commodity contracts that we could match to fixed-price contracts, customer relationships were bifurcated between unhedged and hedged and will be amortized to depreciation and amortization based on the expected future net cash flows by year and expensed to retail cost of revenues are being amortized based on the expected term of the underlying fixed-price contract acquired in each reporting period, respectively.

Trademark

The fair value of the Verde Companies' trademark

Non-compete Agreements. The fair value of non-compete agreements were determined using the differential value approach. Under this approach, we estimated the present value of expected future cash flows of the business with

Table of Contents

and without the non-compete agreement. The difference in discounted cash flows was then adjusted by probability factors related to the likelihood that those with the non-compete agreements would be successful competitors.

Trademarks. The fair value of acquired trademarks is reflective of the value associated with the recognition and reputation of the acquired company to target markets. The fair value of trademarks was valued using a royalty savings method under the income approach. The value was based on the savings we would realize from owning the trademark rather than paying a royalty for the use of that trademark. Under this approach, we estimate the present value of the expected cash flows resulting from avoiding royalty payments to use a third party trademark. In the Verde acquisition, we analyzed market royalty rates charged for licensing trademarks and applied an expected royalty rate to a forecast of estimated revenue, which was then discounted using an appropriate risk adjusted rate of return.The trademark is being amortized over the estimated five -year life of the asset on a straight-line basis.

Goodwill.

The excess of the purchase consideration over the estimated fair value of the amounts initially assigned to the identifiable assets acquired and liabilities assumed was recorded as goodwill.

7. Derivative Instruments
We are exposed to the impact of market fluctuations in the price of electricity and natural gas, basis differences in the price of natural gas, storage charges, RECs, capacity charges from independent system operators, and other ancillary costs. We use derivative instruments in an effort to manage our cash flow exposure to these risks. These instruments are not designated as hedges for accounting purposes, and accordingly, changes in the market value of these derivative instruments are recorded in the cost of revenues. As part of our strategy to optimize pricing in our natural gas related activities, we also manage a portfolio of commodity derivative instruments held for trading purposes. Our commodity trading activities are subject to limits within our Risk Management Policy. For these derivative instruments, changes in the fair value are recognized currently in earnings in net asset optimization revenues.
Derivative assets and liabilities are presented net in our consolidated balance sheets when the derivative instruments are executed with the same counterparty under a master netting arrangement. Our derivative contracts include transactions that are executed both on an exchange and centrally cleared, as well as over-the-counter, bilateral contracts that are transacted directly with third parties. To the extent we have paid or received collateral related to the derivative assets or liabilities, such amounts would be presented net against the related derivative asset or liability's fair value. As of December 31, 2018 and 2017 , we had paid zero and $0.1 million in collateral, respectively. The specific types of derivative instruments we may execute to manage the commodity price risk include the following:

| | |
| • | Forward contracts, which commit us to purchase or sell energy commodities in the future; |
| | |
| • | Futures contracts, which are exchange-traded standardized commitments to purchase or sell a commodity or financial instrument; |
| | |
| • | Swap agreements, which require payments to or from counterparties based upon the differential between two prices for a predetermined notional quantity; and |
| | |
As of the filing date, the Company sold an aggregate of 2,000,000 shares of Series a Preferred Stock. The Company received net proceeds from the offering of approximately $48.9 million (net of underwriting discounts, commissions and a structuring fee).
| • | Option contracts, which convey to the option holder the right but not the obligation to purchase or sell a commodity. |
The Company has entered into other energy-related contracts that do not meet the definition of a derivative instrument or for which we made a normal purchase, normal sale election and are therefore not accounted for at fair value including the following:


� Forward electricity and natural gas purchase contracts for retail customer load; and,
Property and equipment consist of The following amounts as of (in thousands):
� Natural gas transportation contracts and storage agreements.

Class B common stock. RAC assigned the Oasis Note to Retailco on January 4, 2017, and on January 31, 2017 the Oasis Note was converted into 766,180 shares of Class B common stock.

The conversion rate of $7.00 per share for the Oasis Note was fixed as of the date of the execution of the Oasis acquisition agreement on May 12, 2015. Due to a rise in the price of our common stock from May 12, 2015 to the closing of Oasis acquisition on July 31, 2015, the conversion rate of $7.00 per share was below the market price per share of Class A common stock of $8.11 on the issuance date of the Oasis Note on July 31, 2015. As a result, the Company assessed the Oasis Note for a beneficial conversion feature. Due to this conversion feature being "in-the-money" upon issuance, we recognized a beneficial conversion feature based on its intrinsic value of $0.8 million as a discount to the Oasis Note and as additional paid-in capital. This discount was amortized as interest expense under the effective interest method over the life of the Oasis Note through the conversion on January 31, 2017, at which time the remaining $1.0 million beneficial conversion feature was written-off and recognized as interest expense.

Under these arrangements, when the costs that Pacific Summit paid to procure and deliver the gas and electricity exceeded the payments that the Major Energy Companies made attributable to the gas and electricity purchased, the Major Energy Companies incurred interest on the difference. The operating agreements also allowed Pacific Summit to provide credit support. Each form of borrowing incurred interest at the floating 90-day LIBOR rate plus 300 basis points (except for certain credit support guaranties that did not bear interest). In connection with these arrangements, the Major Companies granted first liens to Pacific Summit on a substantial portion of the Major Companies' assets, including present and future accounts receivable, inventory, liquid assets, and control agreements relating to bank accounts.

11. Fair Value Measurements
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. Fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. This includes not only the credit standing of counterparties involved and the impact of credit enhancements.but also the impact of the Company's own nonperformance risk on its liabilities.
We apply fair value measurements to our commodity derivative instruments and a contingent payment arrangements based on the following fair value hierarchy, which prioritizes the inputs to the valuation techniques used to measure fair value into three broad levels:

| | |
| • | Level 1-Quoted prices in active markets for identical assets and liabilities. Instruments categorized in Level 1 primarily consist of financial instruments such as exchange-traded derivative instruments. |
| | |
| • | Level 2-Inputs other than quoted prices recorded in Level 1 that are either directly or indirectly observable for the asset or liability, including quoted prices for similar assets or liabilities in active |

130

Table of Contents

markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived from observable market data by correlation or other means. Instruments categorized in Level 2 primarily include non-exchange traded derivatives such as over-the-counter commodity forwards and swaps and options. |
| | |
| • | Level 3-Unobservable inputs for the asset or liability, including situations where there is little, if any, observable market activity for the asset or liability. The Level 3 category includes estimated earnout obligations related to our acquisitions. |

105

Table of Contents

As the fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable data (Level 3), the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. These levels can change over time. In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. In these cases, the lowest level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy.
Other Financial Instruments
The carrying amount of cash and cash equivalents, accounts receivable, accounts receivable-affiliates, accounts payable, accounts payable-affiliates, accounts payable, and accrued liabilities recorded in the condensed consolidated balance sheets approximate fair value due to the short-term nature of these items. The carrying amounts of the Senior Credit Facility and Prior Senior Credit Facility recorded in the consolidated balance sheets approximate recorded in the condensed consolidated balance sheets approximates fair value because of the variable rate nature of interest on the borrowings thereunder, and are considered Level 2 measurements because interest rates charged are similar to other financial instruments with similar terms and maturities.

As of December 31, 2017 , the estimated earnout obligations were $4.6 million , which was comprised of the Major Earnout and the Stock Earnout in the amount of $4.6 million , and zero , respectively. The final Provider Earnout payment was paid in June 2017. The Verde Earnout was settled for $5.9 million on January 12, 2018 with a promissory note payable to the Seller in June 2019 and is classified as long-term debt as of December 31, 2017 . As of December 31, 2016 , the estimated earnout obligations were $22.7 million , which was comprised of the Provider Earnout, the Major Earnout and the Stock Earnout in the amount of $4.9 million , $17.1 million , and $0.7 million , respectively. As of December 31, 2017 , the estimated earnouts are recorded on our consolidated balance sheets in current liabilities - contingent consideration and long-term liabilities - contingent consideration in the amount of $4.0 million and $0.6 million respectively; and as of December 31, 2016 , in current liabilities - contingent consideration and long-term liabilities - contingent consideration in the amount of $11.8 million and $10.8 million , respectively.our acquisition of the Major Energy Companies in 2016.
The Provider Earnout, the Major Earnout, and the Verde Earnout are discussed in Note 3 "Acquisitions."
The CenStar Earnout was based on a financial measurement attributable to the operations of CenStar for the year following the closing of the acquisition In determining the fair value of the CenStar Earnout, the Company forecasted a one year performance measurement, as defined by the CenStar stock purchase agreement. As this calculation was based on management's estimates of the liability, we had classified the CenStar Earnout as a Level 3 measurement. During the first quarter of 2016, our estimate of the CenStar Earnout was increased to $1.5 million , which was based on the results of operations during such period. In August 2016, we entered into a settlement and release agreement with the seller of CenStar in which the Company paid $1.3 million to such seller and released an additional $0.6 million from escrow in full satisfaction of the earnout obligation under the CenStar stock purchase agreement. During the year ended December 31, 2016, the remaining estimated earnout liability of $0.2 million was written off via a reduction to general and administrative expense in our consolidated statements of operations.
The Provider Earnout was based on achievement by the Provider Companies of a certain customer count criteria over the nine month period following the closing of the Provider Companies acquisition. The sellers of the Provider Companies were entitled to a maximum of $9.0 million and a minimum of $5.0 million in earnout payments based on the level of customer count attained, as defined by the Provider Companies membership interest purchase agreement. In March and June 2017, the Company paid the sellers of the Provider Companies $1.0 million and $4.5 million , respectively, related to the earnout based on the achievement of certain customer count and sales targets.

During the year ended December 31, 2017 , the Company recorded accretion of $0.1 million to reflect the impact of the time value of the liability prior to the final payment in June 2017. The Company additionally recorded $0.5 million of general and administrative expense related to the change in fair value of the earnout prior to the final payment in June 2017. During the period from August 1, 2016 (acquisition date) through December 31, 2016, the Company recorded accretion of $0.1 million to reflect the impact of the time value of the liability. In determining the fair value of the Provider Earnout, the Company forecasted an expected customer count and certain other related criteria and calculated the probability of such forecast being attained. As this calculation was based on management's estimates of the liability, we classified the Provider Earnout as a Level 3 measurement.
The Major Earnout is based on the achievement by the Major Energy Companies of certain performance targets over the 33 month period following NG&E's closing of the Major Energy Companies acquisition (i.e., April 15, 2016). The previous members of Major Energy Companies are entitled to a maximum of $20.0 million in earnout payments based on the level of performance targets attained, as defined by the Major Purchase Agreement. The Stock Earnout obligation is contingent upon the Major Energy Companies achieving the Major Earnout's performance target ceiling, thereby earning the maximum Major Earnout payments. If the Major Energy Companies earn such maximum Major Earnout payments, NG&E would be entitled to a maximum of 400,000 shares of Class B common stock (and a corresponding number of Spark HoldCo units). In determining the fair value of the Major Earnout and the Stock Earnout, the Company forecasted certain expected performance targets and calculated the probability of such forecast being attained. In March 2017, the Company paid the previous members of the Major Energy Companies $7.4 million related to the period from April 15, 2016.through December 31, 2016. During the year ended December 31, 2017 , the Company recorded accretion of $3.8 million to reflect the impact of the time value of the liability. The Company revalued the liability at December 31, 2017 , resulting in the decrease of the fair value of the liability to $4.6 million . During the period from April 15, 2016 (NG&E acquisition date) through December 31, 2016, the Company recorded accretion of $5.0 million to reflect the impact of the time value of the liability. The Company revalued the liability at December 31, 2016, resulting in the write-down of the fair value of the liability to $17.8 million . The impact of the $9.6 million and $1.1 million decrease in fair value is recorded in general and administrative expenses for the years ended December 31, 2017 and 2016 , respectively. As this calculation is based on management's estimates of the liability, we classified the Major Earnout as a Level 3 measurement.
The Verde Earnout was based on achievement by the Verde Companies of certain performance targets over the 18 month period following the closing of the acquisition of the Verde Companies. The Verde Earnout was valued at $5.4 million as of July 1, 2017, the acquisition date. The Company and the Seller agreed to terminate the Verde Earnout on January 12, 2018, and settled the obligation with the issuance of a $5.9 million promissory note payable due to the Seller in June 2019 (the "Verde Earnout Termination Note"). The Company recorded a $0.3 million increase in fair value of the Verde Earnout in general and administrative expenses and classified the liability as long-term debt as of December 31, 2017 . During the year ended December 31, 2017 , the Company recorded accretion of $0.2 million to reflect the impact of the time value of the liability. In determining the fair value of the Verde Earnout, the Company forecasted certain expected performance targets and calculated the probability of such forecast being attained. As the calculation was based on management's estimates of the liability, we classified the Verde Earnout liability as a Level 3 measurement prior to settlement. See discussion of the Verde Earnout Termination Note in Note 8 "Debt."

Assets and Liabilities Measured at Fair Value on a Non-recurring Basis
The Major Earnout is based on the achievement by the Major Energy Companies of certain performance targets over a 33 month period following the date our affiliate acquired the Major Energy Companies and ended on December 31, 2018 . Under the Earnout provisions, the previous members of Major Energy Companies were entitled to a maximum of $20.0 million in earnout payments based on the level of performance targets attained, as defined by the Major Purchase Agreement. The Stock Earnout obligation was contingent upon the Major Energy Companies achieving the Major Earnout's performance target ceiling, thereby earning the maximum Major Earnout payments. If the Major Energy Companies earned such maximum Major Earnout payments, NG&E would be entitled to additional consideration up to a maximum of 400,000 shares of Class B common stock (and a corresponding number of Spark HoldCo units). In determining the fair value of the Major Earnout and the Stock Earnout, we forecasted certain expected performance targets and calculated the probability of such forecast being attained. The impact of the fair value decreases for the years ended December 31, 2018, 2017 and 2016 were recorded in general and administrative expenses.
We apply the provisions of the fair value measurement standard to our non-recurring, non-financial measurements including business combinations as well as impairment related to goodwill and other long-lived assets. For business combinations (see Note 3 "Acquisitions" ), the purchase price is allocated to the assets acquired and liabilities assumed based on a discounted cash flow model for most intangibles as well as market assumptions for the valuation of equipment and other fixed assets. We utilize a discounted cash flow model in evaluating impairment considerations related to goodwill and long-lived assets. Given the unobservable nature of the inputs, The discounted cash flow models are considered to use Level 3 inputs.
10. Accounting for Derivative Instruments
the Company is exposed to the impact of market fluctuations in the price of electricity and natural gas and basis costs, storage and ancillary capacity charges from independent system operators. the Company uses derivative instruments to manage exposure to these risks, and historically designated certain derivative instruments as cash flow hedges for accounting purposes.

The Company holds certain derivative instruments that are not held for trading purposes and are not designated as hedges for accounting purposes. These derivative instruments represent economic hedges that mitigate the Company's exposure to fluctuations in commodity prices. For these derivative instruments, changes in the fair value are recognized currently in earnings in retail revenues or retail cost of revenues.
As part of the Company's strategy to optimize its assets and manage related risks, it also manages a portfolio of commodity derivative instruments held for trading purposes. The Company's commodity trading activities are subject to limits within the Company's Risk Management Policy. For these derivative instruments, changes In the fair value are recognized currently in earnings in net asset optimization revenues.
Derivative assets and liabilities are presented net in the Company's consolidated balance sheets when the derivative instruments are executed with the same counterparty under a master netting arrangement. The Company's derivative contracts include transactions that are executed both on an exchange and centrally cleared, as well as over-the-

counter, bilateral contracts that are transacted directly with a third party. To the extent The Company has paid or received collateral related to the derivative assets or liabilities, such amounts would be presented net against the related derivative asset or liability's fair value As of December 31, 2017 and 2016 , the Company had paid $0.1 million and zero in collateral outstanding, respectively. The specific types of derivative instruments the Company may execute to manage the commodity price risk include the following:
| | |
| • | Forward contracts, which commit The Company to purchase or sell energy commodities in the future; |
The Provider Earnout was based on achievement by the Provider Companies of a certain customer count criteria over a nine month period following the closing of the Provider Companies acquisition. The sellers of the Provider Companies were entitled to a maximum of $9.0 million and a minimum of $5.0 million in earnout payments based on the level of customer count attained, as defined by the Provider Companies membership interest purchase agreement. In determining the fair value of the Provider Earnout, the Company forecasted an expected customer count and certain other related criteria and calculated the probability of such forecast being attained.
| | |
| • | Futures contracts, which are exchange-traded standardized commitments to purchase or sell a commodity or financial instrument; |
| | |
| • | Swap agreements, which require payments to or from counterparties based upon the differential between two prices for a predetermined notional quantity; and, |
| | |
| • | Option contracts, which convey to the option holder the right but not The obligation to purchase or sell a commodity. |
The Company has entered into other energy-related contracts that do not meet the definition of a derivative instrument and are therefore not accounted for at fair value including the following:

� Forward electricity and natural gas purchase contracts for retail customer load; and,
� Natural gas transportation contracts and storage agreements.

13. Income Taxes

We and our subsidiaries, CenStar and Verde Energy USA, Inc. ("Verde Corp") are each subject to U.S. federal income tax as corporations. CenStar and Verde Corp will file consolidated tax returns in jurisdictions that allow combined reporting. Spark HoldCo and its subsidiaries, with the exception of CenStar and Verde Corp, are treated as flow-through entities for U.S. federal income tax purposes, and, as such, are generally not subject to U.S. federal income tax at the entity level. Rather, the tax liability with respect to their taxable income is passed through to their members or partners. Accordingly, we are subject to U.S. federal income taxation on our allocable share of Spark HoldCo's net U.S. taxable income.

In our financial statements, we report federal and state income taxes for our share of the partnership income attributable to our ownership in Spark HoldCo and for the income taxes attributable to CenStar a C-corporation, which is owned by Spark HoldCo. The income tax liability for the partnership does not accrue to the partnership, but rather the investors are responsible for the income taxes based upon the investor's share of the partnership's income. and Verde Corp. Net income attributable to the non-controlling interest in CenStar includes the provision for income taxes related to CenStar and Verde Corp.

The Company accounts for income taxes using the assets and liabilities We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and the tax bases of the assets and liabilities. We apply existing tax law and the tax rate that we expect to apply to taxable income in the years in which those differences are expected to be recovered or settled in calculating the deferred tax assets and liabilities. Effects of changes in tax rates on deferred tax assets and liabilities are recognized in income in the period of the tax rate enactment. A valuation allowance is recorded when it is not more likely than not that some or all of the benefit from the deferred tax asset will be realized.

In December 22, 2017, the President signed the Tax Cuts and Jobs Act ("U.S. Tax Reform which enacts U.S. Tax Reform legislation, which enacted a wide range of changes to the U.S. Corporate income tax system. Accordingly, we adjusted the value of the impact of U.S. Tax Reform primarily represents our estimates of revaluing our U.S. deferred tax assets and liabilities based on the rates at which they are expected to be recognized in the future. For U.S. federal purposes the corporate statutory income tax rate was reduced from 35% to 21% , effective for the 2018 tax year. Based on our historical financial performance, at December 31, 2017 we have a significant net deferred tax asset position that we have remeasured at the lower corporate rate of 21% and recognized a Tax expense to adjust net deferred tax assets to the reduced value.During 2018, we completed our analysis of the impact of U.S. Tax Reform based on further guidance provided on the new tax law by the U.S. Treasury Department and Internal Revenue Service, with no material changes from our assessment performed as of December 31, 2017.

Total income tax expense for the years ended December 31, 2018 and 2017 differed from amounts computed by applying the U.S. federal statutory tax rates to pre-tax income primarily due to state income taxes and the impact of permanent differences between book and taxable income, most notably the income attributable to non-controlling interest, The effective tax rate includes a rate benefit attributable to the fact that Spark HoldCo operates as a limited liability company treated as a partnership for federal and state income tax purposes and is not subject to federal and state income taxes. Accordingly, the portion of earnings attributable to non-controlling interest is subject to tax when reported as a component of the non-controlling interest's taxable income. The effective rate in 2017 includes a $13.2 million unfavorable impact resulting from which gets taxed at the non-controlling interest partner level. The effective rate in 2017 was also impacted by the enactment of U.S. Tax Reform. The primary impact of the change in tax law was the remeasurment of our U.S. federal deferred tax assets and liabilities at the tax rate expected to be applied when the temporary differences are settled at a rate of 21% .Since we were in a net deferred tax asset position, the rate reduced our overall asset having an unfavorable effect on tax expense.

The Company accounts for income taxes using the assets and liabilities method. deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and those assets and liabilities tax bases. The Company applies existing tax law and the tax rate that the Company expects to apply to taxable income in the years in which those differences are expected to be recovered or settled in calculating the deferred tax assets and liabilities. Effects of changes in tax rates on deferred tax assets and liabilities are recognized in income in the period of the tax rate enactment. We remeasured our deferred tax assets and liabilities, excluding those that will be included on our 2017 tax return based on the rates we expect to realize the deferred tax assets and liabilities at in the future. The amount that was recorded related to the remeasurement of our deferred tax balance was $13.2 million of tax expense.A valuation allowance is recorded when it is not more likely than not that some or all of the benefit from the deferred tax asset will be realized.

Regulatory Matters

On April 9, 2018 the Attorney General for the State of Illinois filed a complaint against Major Energy Electric Services, LLC (Major) asserting claims that Major engaged in a pattern and practice of deceptive conduct intended to defraud Illinois consumers through door-to-door and telephone solicitations, in-person solicitations at retail establishments, advertisements on its website and direct mail advertisements to sign up for electricity services. The complaint seeks injunctive relief and monetary damages representing the amounts Illinois consumers have allegedly lost due to fraudulent marketing activities. The Attorney General also requests civil penalties under the Consumer Fraud Act and to revoke Major's authority to operate in the state. The complaint was filed in the Circuit Court of Cook County, Illinois, County Department, Chancery Division. Major filed its motion to dismiss on August 1, 2018. On October 10, 2018, the court denied Major's Motion to Dismiss and subsequently its motion for reconsideration. Major is appealing the lower court's ruling with a Motion for Entry of a Certified Question. Appellate briefs are due in February 2019 and discovery has begun. Major denies the allegations asserted and intends to vigorously defend this matter, however, we cannot predict the outcome or consequences of this case at this time.

Spark Energy, LLC (Spark) is the subject of two current investigations by the Connecticut Public Utilities Regulatory Authority (PURA). The first investigation constitutes a notice of violation (NOV) and assessment of a proposed civil penalty in the amount of $0.9 million primarily for Spark's alleged failure to comply with requirements implemented in 2016 that customer bills include any changes to existing rates effective for the next billing cycle. After a hearing process was concluded and Spark Energy, LLC filed a brief challenging the legal authority of PURA to enforce the NOV and impose civil penalties for the alleged violations, PURA suspended the proceeding and opened a proceeding offering amnesty to ESCOs that self-report violations and offer to voluntarily remit refunds to customers. Spark has announced its intention to participate in the amnesty proceeding. The second investigation involves a NOV alleging improper marketing practices of one of Spark Energy, LLC's former outbound telemarketing vendors and assessment of a proposed civil penalty of $0.8 million . Certain agents managed by this vendor were allegedly using an unauthorized script in outbound marketing calls. We are unable to predict the outcome of these proceedings but have accrued $0.2 million as of December 31, 2018 , which represents our current estimate for penalty exposure for these two matters. While investigations of this nature have become common and are often resolved in a manner that allows the retailer to continue operating in Connecticut, there can be no assurance that PURA will not take more severe action.

16. Segment Reporting

Our determination of reportable business segments considers the strategic operating units under which the Company makes financial decisions, allocates resources and assesses performance of its retail and asset optimization businesses.we make financial decisions, allocate resources and assess performance of our business. Our
The Company's reportable business segments are retail electricity and retail natural gas. The retail electricity segment consists of electricity sales and transmission to residential and commercial customers. The retail natural gas segment consists of natural gas sales to, and natural gas transportation and distribution for, residential and commercial customers. Asset optimization activities, considered an integral part of securing the lowest price natural gas to serve retail gas load, are part of the retail natural gas segment. the Company Corporate and other consists of expenses and assets of the retail natural gas and retail electricity segments that are managed at a consolidated level such as general and administrative expenses. Asset optimization activities are also included in Corporate and other. For the years ended December 31, 2018 , 2017 and 2016 , we recorded asset optimization revenues of $178.3 million , $133.0 million and $154.1 $113.7 million , $178.3 million and $133.0 million and asset optimization cost of revenues of $179.0 million , $133.6 million and $152.6 million for the years ended December 31, 2017 , 2016 and 2015 $109.2 million , $179.0 million and $133.6 million , respectively, which are presented on a net basis in asset optimization revenues.The retail electricity segment consists of electricity sales and transmission to residential and commercial customers. Corporate and other consists of expenses and assets of the retail natural gas and retail electricity segments that are managed at a consolidated level such as general and administrative expenses.

The acquisitions of CenStar and Oasis in 2015, acquisitions of Major Energy Companies and Provider Energy Companies in 2016, and acquisitions of the Perigee Companies and Verde Companies in 2017 had no impact on our reportable business segments as the portions of those acquisitions related to retail natural gas and retail electricity have been included in those existing business segments.
We use retail gross margin to assess the performance of our operating segments. Retail gross margin is defined
to assess the performance of the Company's operating segments. the Chief Operating Decision Maker analyzes Retail gross margin The Company defines retail gross margin
as operating income (loss) plus (i) depreciation and amortization expenses and (ii) general and administrative expenses, less (i) net asset optimization revenues (expenses), (ii) net gains (losses) on non-trading derivative instruments, and (iii) net current period cash settlements on non-trading derivative instruments. We deduct net gains (losses) on non-trading derivative instruments, excluding current period cash settlements, from the retail gross margin calculation in order to remove the non-cash impact of net gains and losses on these derivative instruments.
Retail gross margin is a primary performance measure used by our management to determine the performance of our retail natural gas and electricity business by removing the impacts of our asset optimization activities and net non-cash income (loss) impact of our economic hedging activities. As an indicator of our retail energy business' operating performance, Retail gross margin should not be considered an alternative to, or more meaningful than, operating income, as determined in accordance with GAAP.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Based on this evaluation, management concluded that our disclosure controls and procedures were effective as of December 31, 2018 at the reasonable assurance level.

Management's Annual Report on Internal Control Over Financial Reporting

See "Management's Report on Internal Control Over Financial Reporting" under Item 8 of this Annual Report on Form 10-K.

Attestation Report of the Independent Registered Public Accounting Firm

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm on our internal control over financial reporting because Section 103 of the JOBS Act provides that an emerging growth company is not required to provide an auditor's report on internal control over financial reporting for as long as we qualify as an emerging growth company.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended December 31, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting, expect as described below.

Item 9B. Other Information

None.




On March 7, 2018, Spark HoldCo entered into an asset purchase agreement (the "Customer Purchase Agreement") with NG&E. Pursuant to the terms of the Customer Purchase Agreement, Spark HoldCo has agreed to purchase, and NG&E has agreed to sell, a portfolio of approximately 50,000 RCEs located in 24 markets in eight states. We expect these customers will begin transferring after April 1, 2018. The purchase price under the Customer Purchase Agreement is a cash payment of $250 for each RCE, or approximately $12.5 million in the aggregate and will be funded with cash on hand.

Spark HoldCo and NG&E have made customary representations, warranties and covenants in the Customer Purchase Agreement. Consummation of the transactions contemplated by the Customer Purchase Agreement is subject to various conditions, including, among others, (1) that no order or decree prohibits the transaction, and (2) that the parties have not otherwise agreed to mutually terminate the agreement before the transfer of the customers. The Customer Purchase Agreement requires the parties to deliver certain ancillary documents. The Customer Purchase Agreement also contains termination provisions and indemnification provisions.

The terms of the Customer Purchase Agreement were approved by our Board of Directors after approval by a special committee of the Board of Directors. The special committee was composed exclusively of independent members of our Board of Directors. NG&E is owned by W. Keith Maxwell III, our Chairman of the Board, founder and majority shareholder.

The foregoing summary of the Customer Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the complete terms of the Customer Purchase Agreement, a copy of which is attached as Exhibit 2.7 to this Annual Report and is incorporated in this Item 9B by reference. The Customer Purchase Agreement has been filed as an exhibit to this Annual Report to provide investors and security holders with more complete information regarding its terms. The Customer Purchase Agreement is not intended to provide any other factual information about Spark HoldCo. The representations, warranties and covenants contained in the Customer Purchase Agreement were made only for purposes of the Customer Purchase Agreement and as of specific dates, were solely for the benefit of the parties to the Customer Purchase Agreement, and may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Customer Purchase Agreement. The representations and warranties may have been made for the purposes of allocating contractual risk between the parties instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under the agreements and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Spark HoldCo or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the agreements, which subsequent information may or may not be fully reflected in the public disclosures of the Company.

Termination of Master Service Agreement

Additionally, certain of Retailco Services employees who previously provided services to Spark HoldCo under the Master Service Agreement will become employees of Spark HoldCo, and certain contracts, assets, and intellectual property that were assigned under the Master Service Agreement will be assigned back to Spark HoldCo. To assist in the transition of these services and assets back to Spark HoldCo, Retailco Services is obligated to provide transition services to Spark HoldCo for a period of six months. Spark HoldCo is not obligated to pay any consideration for the MSA Termination Agreement or the termination of the Master Service Agreement.

The MSA Termination Agreement and the termination of the Master Service Agreement was approved by our Board of Directors after approval by a special committee of the Board of Directors. The Special Committee was composed exclusively of independent members of our Board of Directors. Retailco Services is owned by W. Keith Maxwell III, our Chairman of the Board, founder and majority shareholder.

1.2 Interpretations . In this Agreement, unless a clear contrary intention appears: (a) the singular includes the plural and vice versa; (b) reference to a Person includes such Person's successors and assigns but, in the case of a Party, only if such successors and assigns are permitted by this Agreement, and reference to a Person in a particular capacity excludes such Person in any other capacity; (c) reference to any gender includes each other gender; (d) references to any Exhibit, Schedule, Section, Article, Annex, subsection and other subdivision refer to the corresponding Exhibits, Schedules, Sections, Articles, Annexes, subsections and other subdivisions of this Agreement unless expressly provided otherwise; (e) references in any Section or Article or definition to any clause means such clause of such Section, Article or definition; (f) "hereunder," "hereof," "hereto" and words of similar import are references to this Agreement as a whole and not to any particular provision of this Agreement; (g) the word "or" is not exclusive, and the word "including" (in its various forms) means "including without limitation"; (h) each accounting term not otherwise defined in this Agreement has the meaning commonly applied to it in accordance with GAAP; (i) references to "days" are to calendar days; and (j) all references to money refer to the lawful currency of the United States.

ARTICLE II
SALE AND PURCHASE OF PURCHASED ASSETS
2.1 Sale of Assets. In reliance on the representations, warranties and agreements contained herein, and subject to the terms and conditions of this Agreement, Buyer hereby agrees to purchase from NGE and NGE hereby agrees to sell and convey to Buyer or, in each case, Buyer's designee, all of NGE's right, title and interest in and to the following (collectively, the " Purchased Assets "):
(a) the retail electricity and natural gas customer contracts listed in Schedule 2.1(a) (as the same may be updated from time to time prior to the initial Effective Transfer Date) having delivery points with the utilities and in the States listed in Schedule 2.1(a) attached hereto ( the "Purchased Contracts") ; and
(b) a customer list, third-party verification (" TPV ") (to the extent applicable) and or incoming telephone enrollment recordings, account names, and other documentation and databases, including all records, files and data relating to the Purchased Contracts listed on Schedule 2.1(a) (as the same may be updated from time to time prior to final Effective Transfer Date).
(c) all of NGE's right, title, benefit, privileges and interest in and to each of the Hedge agreements set forth on Schedule 2.1(c) (the " Hedge Agreements "), insofar and only insofar as the Hedge Agreements apply to, or are utilized to hedge electric or natural gas commodity prices directly related and attributable to, the Purchased Contracts.
2.2 Excluded Assets. Other than the Purchased Assets to be transferred by NGE to Buyer pursuant to this Agreement and described in Section 2.1 , Buyer expressly understands and agrees that it is not purchasing or acquiring, and NGE is not selling or assigning, any other assets or properties of NGE and all such other assets or properties shall be excluded from the Purchased Assets (the " Excluded Assets "). The Purchased Assets shall exclude any receivables or right of payment arising from the sale and delivery of electricity, natural gas, or other commodities and services pursuant to the terms and conditions of a Purchased Asset prior to the Effective Transfer Date for such Purchased Asset. The Purchased Assets shall include only those Purchased Contracts with on-flow customers of NGE for which at the applicable Effective Transfer Date: (a) no standby/supplemental service has been elected by NGE pursuant to any tariff to which the applicable utility from which a customer obtains delivery of electricity or natural gas is subject; (b) there are no pending, unresolved informal or formal complaints against NGE with any governmental agency, utility, LDC or ISO; and (c) there is no payment in arrears over thirty (30) days. For purposes of this Agreement, a customer under a Purchased Contract meeting the qualifications in (a), (b) and (c) shall be defined as a " Qualified Customer " and a customer not meeting such qualifications shall be defined as a " Non-Qualified Customer ").
2.3 Purchase Price; Adjustments to Purchase Price. The consideration for the transfer of the Purchased Assets by NGE to Buyer shall be Buyer's assumption of the obligations described in Section 2.4 and a purchase price (the " RCE Purchase Price ") of $250 for each RCE attributable to the Purchased Contracts.
(a) The RCE Purchase Price for each Purchased Contract described in Section 2.3(a) that (A) has been validly transferred to Buyer; (B) for which the applicable LDC/Utility has accepted enrollment for retail electric service upon the next available read cycle; and (C) has come on flow with Buyer through written confirmation from Buyer (the " Effective Transfer Date " for such Purchased Contract), shall be paid to NGE for the RCE Purchase Price within one week of the applicable Effective Transfer Date; provided that payment for RCEs that NGE enrolled on the internet shall be made subject to and in accordance with subsection (c) below.
(b) For each RCE applicable to the Purchased Contracts of customers who enrolled with NGE on the internet, payment shall be made only for those internet-enrolled customers that remain on-flow with Buyer for 60 consecutive calendar days following the applicable Effective Transfer Date and for which no cancellation or drop request has been submitted into the applicable LDC/utility subsequent to the first full read cycle following the applicable Effective Transfer Date for such Purchased Contract. Buyer shall pay NGE the RCE Purchase Price no later than 10 Business Days following the end of each applicable 60 day period.
(c) Buyer shall be entitled to a full refund of the RCE Purchase Price attributable to any RCEs: (i) that do not come on flow with Buyer, or (ii) with Non-Qualified Customers immediately upon confirmation by Buyer of the occurrence of either of the matters set forth in (i) or (ii) above. Any amounts to be refunded hereunder may be set off by Buyer from future payments due to Seller.
2.4 Assumption of Certain Obligations. Upon sale and purchase of the Purchased Assets, Buyer shall, subject to Section 2.5 , assume all obligations arising or required to be performed after the applicable Effective Transfer Date under each Purchased Contract (other than any liability arising under the Purchased Contracts arising out of or relating to a breach of any such Purchased Contract that occurred prior to the applicable Effective Transfer Date) (the " Assumed Obligations "); provided that in no event shall Buyer be deemed to assume any obligations under a Purchased Contract until that Purchased Contract comes on-flow to Buyer. Within one hundred eighty (180) days after the last of the Purchased Contracts are assigned by NGE to Buyer, NGE and Buyer shall audit each of their respective records to determine whether any errors occurred or any modifications to the calculations made pursuant to this Section 2.4 need to be made, based on updated information or otherwise, and thereafter shall true up the payments previously made to reflect such corrections or modifications. The Party that owes money to the other Party shall make payment to the other Party within ten (10) Business Days of the final true up by the Parties or the final determination thereof. In addition, as a condition to the transfer of each RCE, Buyer or Buyer's designee, NGE and the applicable Hedge Counterparty shall enter into a Novation Agreement pursuant to which NGE, effective as of 12:01 am, on May 1, 2018 (the " Hedge Transfer Effective Date ") assigns all of its rights, and Buyer assumes all of NGE's obligations, under the Hedge Agreements applicable to each Purchased Contract as of the Hedge Transfer Effective Date, unless such Purchased Contract is never assigned to Buyer. Since the Purchased Contracts may not be effectively transferred to Buyer as of the Hedge Transfer Effective Date, NGE and Buyer agree to account for any mark-to-market losses or gains sustained by Buyer after the Hedge Transfer Effective Date attributable to those Purchased Contracts that are assigned to Buyer and whose Effective Transfer Date occurs subsequent to the Hedge Transfer Date, but solely for the period prior to each applicable Effective Transfer Date, as follows:
(a) With respect to those Purchased Contracts assigned by NGE to Buyer whose Effective Transfer Date occurs subsequent to the Hedge Transfer Effective Date, after the end of each Month NGE and Buyer shall calculate the mark-to-market losses or gains sustained by Buyer attributable to such Purchased Contracts during such month covering the period from the Hedge Transfer Effective Date through the applicable Effective Transfer Date for each such Purchased Contract. Upon final agreement or determination of such mark-to-market losses, Buyer shall invoice NGE for the mark-to-market losses or gains incurred by Buyer and NGE shall pay to Buyer such mark-to-market losses and Buyer shall pay to NGE such mark-to-market gains within ten (10) Business Days of NGE's receipt of such invoice.
(b) For the purposes of this Section 4 , " mark-to-market losses or gains " shall be calculated based on the difference between the price set forth in the applicable Hedge Agreement for the particular product involved and the current monthly quote or to the end of month quote (if the Effective Transfer Date does not occur on the 1 st day of a particular month) for the particular product involved and based on the same quantity of such product as set forth in the Hedge Agreement based on the applicable zonal locational marginal pricing (" LMP ") settlements or other similar types of settlements, as of the day of the initial Effective Transfer Date. Such mark-to-market losses or gains shall be allocated among NGE and Buyer on a percentage or share basis as follows:
(i) During the period from the Hedge Transfer Effective Date to each Effective Transfer Date occurring subsequent to the Hedge Transfer Effective Date (i.e., during the period Buyer is bearing one hundred percent (100%) of all gains and losses attributable to the Hedge Agreements), NGE's percentage share of such losses or gains (" NGE's Percentage Share ") shall be the quotient or percentage obtained by dividing (A) the actual volumes delivered under the Purchased Contracts from the Hedge Transfer Effective Date and ending on the applicable Effective Transfer Date, by (B) the actual volumes delivered under all Purchased Contracts during the same time period. If there is a mark-to-market loss, NGE shall pay to Buyer NGE's Percentage Share of such losses. If there is a mark-to-market gain, Buyer shall pay to NGE NGE's Percentage share of such gain.
(c) Within one hundred eighty (180) days after the last of the Purchased Contracts are assigned by NGE to Buyer, NGE and Buyer shall audit each of their respective records to determine whether any errors occurred or any modifications to the calculations made pursuant to this Section 2.4 need to be made, based on updated information or otherwise, and thereafter shall true up the payments previously made to reflect such corrections or modifications. The Party that owes money to the other Party shall make payment to the other Party within ten (10) Business Days of the final true up by the Parties or the final determination thereof.
(d) If the Parties are unable to agree on the calculations of the mark-to-market losses sustained by a Party or are unable to agree on the final true up of such mark-to-market losses, at the request of either Party, such determination shall be made by the Independent Accountant for final resolution. In such event, the Parties shall direct the Independent Accountant to resolve the disputes within thirty (30) days after the relevant materials are submitted for review. The Independent Accountant shall consider only those items or amounts that remain in dispute between the Parties, shall render its decision based solely on written materials submitted by the Parties and the terms of this Agreement, and shall not assign a value to any item greater than the greatest value for such item claimed by either Buyer or NGE or less than the smallest value for such item claimed by either Buyer or NGE. The Independent Accountant shall have exclusive jurisdiction over, and resort to the Independent Accountant as provided in this Section 2.4(d) shall be the sole recourse and remedy of Buyer and NGE against one another or any other Person with respect to, any disputes arising out of or relating to the mark-to-market calculations or the true up of such calculations. The decisions of the Independent Accountant regarding the mark-to-market calculations and the true up of such calculations shall be enforceable in a court of law. The fees and expenses associated with the Independent Accountant shall be borne fifty percent (50%) by Buyer and fifty percent (50%) by NGE.

(c) any liabilities of NGE for any present or former brokers or agents;

(e) any liabilities of NGE for any present or former wholesale supplier of electricity or natural gas arising out of, in respect of or in connection to, the Purchased Contracts, except for the obligations under the Hedge Agreements;
(f) any liabilities of NGE for any present or former applicable local distribution company/utility arising out of, in respect of or in connection to, the Purchased Assets, including, without limitation, imbalance payments, fines, penalties, and refunds; and
(g) any liabilities arising from the failure by NGE or any of its Affiliates to comply with any federal, state or local law or governmental order arising out of, in respect of or in connection to, the Purchased Assets.
2.6 Tax Allocation of Purchase Price . The Purchase Price shall be allocated among the Purchased Assets for tax purposes in a manner mutually agreeable to NGE and Buyer (within ninety (90) days following the final Effective Transfer Date) and consistent with Section 1060 of the Internal Revenue Code and the Treasury Regulations promulgated thereunder as Class VI identifiable intangible assets. NGE and Buyer shall file all information reports and Tax Returns (and any amendments thereto or claims for refund) in a manner consistent with this Section 2.6 (including, without limitation, Internal Revenue Service Form 8594 or any successor form).

NGE shall pay one hundred percent (100%) of any and all sales or gross receipt taxes that may be owed in connection with the sale and transfer of the Purchased Assets. NGE and Buyer shall reasonably cooperate to obtain any available exemptions with respect to such Taxes in all states in which any of the Purchased Assets are located.
(c) For Tax purposes, the parties agree to treat all payments made under Article III or under any indemnity provisions contained in this Agreement, or for breaches of representations, warranties, covenants or agreements, as adjustments to the Purchase Price.
2.8 Payment of Taxes and Other Expense. If Buyer or NGE receives an invoice for any Tax or other expense which is allocable to the other Party in part or in full, the recipient shall forward a copy of the invoice promptly to the other Party with a written statement of the amounts the recipient reasonably believes are owed by the other Party.

8.4 Indemnification Procedures.
(a) Each Indemnitee agrees that promptly after it becomes aware of facts giving rise to a claim by it for indemnification pursuant to this Article VIII , including receipt by it of notice of any Proceeding, by any third party with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, such Indemnitee must assert its claim for indemnification under this Article VIII (each, a " Claim ") by providing a written notice (a " Claim Notice ") to the Indemnifying Party allegedly required to provide indemnification protection under this Article VIII specifying, in reasonable detail, the nature and basis for such Claim ( e.g. , the underlying representation, warranty, covenant or agreement alleged to have been breached). Such notice shall include a formal demand for indemnification under this Agreement. Notwithstanding the foregoing, an Indemnitee's failure to send or delay in sending a third party Claim Notice will not relieve the Indemnifying Party from liability hereunder with respect to such Claim except to the extent the Indemnifying Party is materially prejudiced by such failure or delay and except as is otherwise provided herein. If the Indemnified Party knowingly failed to notify the Indemnifying Party thereof in accordance with the provisions of this Agreement in sufficient time to permit the Indemnifying Party or its counsel to defend against such matter and to make a timely response thereto including any responsive motion or answer to a complaint, petition, notice or other legal, equitable or administrative process relating to the Claim, the Indemnifying Party's indemnity obligation relating to such Claim shall be limited to the extent that such knowing failure to notify the Indemnifying Party has actually resulted in material prejudice or damage to the Indemnifying Party. Except as specifically provided herein, each Indemnitee's rights and remedies set forth in this Agreement will survive and will not be deemed waived by such Indemnitee's consummation of the transactions contemplated hereby and will be effective regardless of any inspection or investigation conducted, or the awareness of any matters acquired (or capable or reasonably capable of being acquired), by or on behalf of such Indemnitee or by its directors, officers, employees, or representatives or at any time (regardless of whether notice of such knowledge has been given to the Indemnifying Party), whether before or after the Execution Date or the final Effective Transfer Date, as applicable, with respect to any circumstances constituting a condition under this Agreement.
(b) In the event of the assertion of any third party Claim for which, by the terms hereof, an Indemnifying Party is obligated to indemnify an Indemnitee, the Indemnifying Party will have the right, at such Indemnifying Party's expense, to assume the defense of same including the appointment and selection of counsel on behalf of the Indemnitee so long as such counsel is reasonably acceptable to the Indemnitee. If the Indemnifying Party elects to assume the defense of any such third party Claim, it shall within 30 days of its receipt of the Claim Notice notify the Indemnitee in writing of its intent to do so. Any such contest may be conducted in the name and on behalf of the Indemnifying Party or the Indemnitee as may be appropriate. The Indemnifying Party will have the right to settle or compromise or take any corrective or remediation action with respect to any such Claim by all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnifying Party to a final conclusion or settled at the reasonable discretion of the Indemnifying Party. The Indemnitee will be entitled, at its own cost, to participate with the Indemnifying Party in the defense of any such Claim. If the Indemnifying Party assumes the defense of any such third-party Claim but fails to diligently prosecute such Claim, or if the Indemnifying Party does not assume the defense of any such Claim, the Indemnitee may assume control of such defense and in the event it is determined pursuant to the procedures set forth in this Article VIII that the Claim was a matter for which the Indemnifying Party is required to provide indemnification under the terms of this Article VIII , the Indemnifying Party will bear the reasonable and documented costs and expenses of such defense (including reasonable and documented attorneys' fees and expenses).
(c) If requested by the Indemnifying Party, the Indemnitee agrees to reasonably cooperate with the Indemnifying Party and its counsel in contesting any Claim that the Indemnifying Party elects to contest or, if appropriate, in making any counterclaim against the Person asserting the Claim, or any cross-complaint against any Person, and the Indemnifying Party will reimburse the Indemnitee for any reasonable and documented expenses incurred by it in so cooperating. At no cost or expense to the Indemnitee, the Indemnifying Party shall reasonably cooperate with the Indemnitee and its counsel in contesting any Claim.
(d) Notwithstanding anything to the contrary in this Agreement, the Indemnifying Party will not be permitted to settle, compromise, take any corrective or remedial action or enter into an agreed judgment or consent decree, in each case, that subjects the Indemnitee to any criminal liability, requires an admission of guilt, wrongdoing or fault on the part of the Indemnitee or imposes any continuing obligation on or requires any payment from the Indemnitee without the Indemnitee's prior written consent.
(e) Notwithstanding anything in this Article VIII to the contrary, any indemnification payment to be made to an Indemnitee pursuant to this Article VIII shall be effected by wire transfer of immediately available funds from the Indemnifying Party to an account designated by the Indemnitee within ten (10) days after the final determination thereof.
8.5 Express Negligence . THE PARTIES INTEND THAT THE INDEMNITIES SET FORTH IN THIS ARTICLE VIII BE CONSTRUED AND APPLIED AS WRITTEN ABOVE, NOTWITHSTANDING ANY RULE OF CONSTRUCTION TO THE CONTRARY. WITHOUT LIMITING THE FOREGOING, SUCH INDEMNITIES SHALL APPLY NOTWITHSTANDING ANY STATE'S "EXPRESS NEGLIGENCE" OR SIMILAR RULE THAT WOULD DENY COVERAGE BASED ON AN INDEMNIFIED PARTY'S SOLE OR CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OR GROSS NEGLIGENCE. IT IS THE INTENT OF THE PARTIES THAT, TO THE EXTENT PROVIDED ABOVE, THE INDEMNITIES SET FORTH IN THIS ARTICLE VIII SHALL APPLY TO AN INDEMNIFIED PARTY'S SOLE OR CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OR GROSS NEGLIGENCE. THE PARTIES AGREE THAT THIS PROVISION IS "CONSPICUOUS" FOR PURPOSES OF ALL STATE LAWS.
8.6 No Reliance .

3. Confidential Information. Any Party (the "Disclosing Party") may from time to time disclose Confidential Information to any other Party (the "Recipient"). "Confidential Information" is all non-public, confidential, and/or proprietary information concerning the business, technology, and strategies of the Disclosing Party that is conveyed to the Recipient orally or in tangible form and is either identified or marked as "confidential" or "proprietary" or, under the circumstances surrounding its disclosure, or due to its nature or sensitivity, should be reasonably understood by the Recipient as intended by the Disclosing Party to be treated as "confidential" and subject to the terms of this Agreement. Without limiting the generality of the foregoing, each Party agrees that (a) Confidential Information of Servco includes the software, source code, documentation, inventions, know-how, methods, designs, specifications, updates and any and all other materials and information related to the Services; and (b) Confidential Information of Client includes all Client Data, Client Intellectual Property, Client business processes, Client marketing strategies and copies and details of the Client's agreements with its customers. For a period of two (2) years after the Termination Date (and indefinitely or as otherwise prescribed with respect to any Confidential Information that meets the definition of a "Trade Secret" under then applicable law and any personally identifying information, including without limitation names, addresses, and e-mail addresses), Recipient will keep in confidence and trust and will not disclose or disseminate, or permit any employee, agent or other party working under Recipient's direction to disclose or disseminate, the existence, source, content or substance of any Confidential Information to any other party. Recipient shall use Confidential Information of the Disclosing Party only as necessary for the performance of this Agreement. Recipient will employ at least the same methods and degree of care (but no less than reasonable care) as Recipient employs with respect to its own Confidential Information of similar import to prevent the unauthorized disclosure or misappropriation of the Disclosing Party's Confidential Information. Recipient will furnish the Confidential Information only to its and its affiliates' employees, independent contractors, and agents who have (a) a bona fide need to know the Confidential Information to perform the obligations hereunder, (b) been informed of the confidential nature of the Confidential Information, and (c) agreed in writing to be bound by obligations of confidentiality no less restrictive than the terms and conditions set forth in this Agreement. The Receiving Party shall be responsible for any breach of confidentiality by such persons. The commitments in this Agreement will not impose any obligations on the Recipient





with respect to any portion of the Confidential Information which: (i) is now generally known or available, or which hereafter, through no wrongful act or failure to act on the part of Recipient, becomes generally known or available in the public domain; (ii) is rightfully known by the Recipient prior to or at the time of receiving such information from the Disclosing Party or its representatives; (iii) is furnished to Recipient by a third party without any known restriction on disclosure and without a breach by such third party of any confidentiality undertaking with respect thereto; (iv) is independently developed by the Recipient without the use of the Disclosing Party's Confidential Information or the breach of this Agreement; or (v) is approved for disclosure without further obligations of confidentiality by the express written authorization of the Disclosing Party. Notwithstanding anything herein to the contrary, the Recipient may disclose Confidential Information that is required to be disclosed by order or mandate of any court, tribunal or administrative agency, or other instrumentality of the government; provided , however , that the Recipient shall give the Disclosing Party as much advance notice prior to making such disclosure as is reasonably practicable under the circumstances and to the extent legally permissible so as to permit the Disclosing Party to take commercially reasonable actions at its own expense to prevent or mitigate the adverse effects of such disclosure. Each Party acknowledges that monetary damages may not be a sufficient remedy for the unauthorized disclosure or improper use of Confidential Information and, accordingly, that each Party may seek, without waiving any of its other rights or remedies, such injunctive or equitable relief as may be available in a court of competent jurisdiction. At the Disclosing Party's option and direction, Recipient shall promptly either destroy all Confidential Information in its possession or return all such copies to the Disclosing Party, and, in either event, Recipient shall provide a written certification confirming such destruction or return. Notwithstanding the foregoing, to the extent any Servco Confidential Information is transferred to Client pursuant to Sections 2.3 of this Agreement, or is within the knowledge of Servco personnel who become employees of Client pursuant to Section 2.6 of this Agreement, such Confidential Information shall become the property of Client, and Client shall be free to use such Confidential information as it sees fit and shall not be restricted in any way from using such Confidential Information.
4. Alternative Dispute Resolution Procedures
4.1 Any dispute, controversy or claim arising out of or relating to this Agreement or the breach or performance hereof, including, but not limited to, any disputes concerning the interpretation of the terms and provisions hereof, shall be resolved through the use of the following procedures:
| | |
| (a) | The Parties will initially attempt in good faith to resolve any disputes, controversy or claim arising out of or relating to this Agreement. |

| | |
| (b) | Should the Parties directly involved in any dispute, controversy or claim be unable to resolve same within a reasonable period of time, such dispute, controversy or claim shall be submitted to the senior executives of the Parties (the " Senior Executives ") with such explanation or documentation as the Parties deem appropriate to aid the Senior Executives in their consideration of the issues presented. The date the matter is first submitted to the Senior |





Executives shall be referred to as the " Submission Date ." The Senior Executives shall attempt in good faith, through the process of discussion and negotiation, to resolve any dispute, controversy, or claim presented to it within ten (10) Days after the Submission Date.

| | |
| (c) | If the Senior Executives cannot so resolve any dispute, controversy, or claim submitted to it within ten (10) Days after the Submission Date, the Parties shall attempt in good faith to settle the matter by submitting the dispute, controversy or claim to mediation within twenty (20) Days after the Submission Date using any mediator upon which they mutually agree. If the Parties are unable to mutually agree upon a mediator, the case shall be referred for mediation to the office of Judicial Arbitration and Mediation Services, Inc. ("JAMS") in Houston, Texas. The cost of the mediator will be split equally between the Parties unless they agree otherwise in writing. |

| | |
| (d) | If the matter has not been resolved pursuant to the aforesaid mediation procedure within thirty (30) Days of the initiation of such procedure, or if either Party will not participate in such mediation, either Party may request that the matter be resolved through arbitration by submitting a written notice (the " Arbitration Notice ") to the other. Any arbitration that is conducted hereunder shall be governed by the Federal Arbitration Act, 9 U.S.C. § 1 et seq. , and will not be governed by the arbitration acts, statutes, or rules of any other jurisdiction. |

| | |
| (e) | The Arbitration Notice shall name the noticing Party's arbitrator and shall contain a statement of the issue(s) presented for arbitration. Within fifteen (15) Days of receipt of an Arbitration Notice, the other Party shall name its arbitrator by written notice to the other and may designate any additional issue(s) for arbitration. The two named arbitrators shall select the third arbitrator within fifteen (15) Days after the date on which the second arbitrator was named. Should the two arbitrators fail to agree on the selection of the third arbitrator, either Party shall be entitled to request the Senior Judge of the United States District Court for the Southern District of Texas to select the third arbitrator. All arbitrators shall be qualified by education or experience within the electric and natural gas retail marketing industry to decide the issues presented for arbitration. No arbitrator shall be: (i) a current or former director, officer, or employee of either Party or its Affiliates; (ii) an attorney (or member of a law firm) who has rendered legal services to either Party or its Affiliates within the preceding three years; or (iii) an owner of any of the Voting Interest of either Party, or its Affiliates. |

| | |
| (f) | The three arbitrators shall commence the arbitration proceedings within twenty-five (25) Days following the appointment of the third arbitrator. The arbitration proceedings shall be held at a mutually acceptable site and if the |





Parties are unable to agree on a site, the arbitrators shall select the site. The arbitrators shall have the authority to establish rules and procedures governing the arbitration proceedings. Each Party shall have the opportunity to present its evidence at the hearing. The arbitrators may call for the submission of pre-hearing statements of position and legal authority, but no post-hearing briefs shall be submitted. The arbitration panel shall not have the authority to award (i) punitive or exemplary damages or (ii) consequential damages, except as expressly provided herein. The arbitrators' decision must be rendered within thirty (30) Days following the conclusion of the hearing or submission of evidence, but no later than ninety (90) Days after appointment of the third arbitrator.

| | |
| (g) | The decision of the arbitrators or a majority of them, shall be in writing and shall be final and binding upon the Parties as to the issue(s) submitted. The cost of the hearing shall be shared equally by the Parties, and each Party shall be responsible for its own expenses and those of its counsel or other representatives. Each Party hereby irrevocably waives, to the fullest extent permitted by law, any objection it may have to the arbitrability of any such disputes, controversies or claims and further agrees that a final determination in any such arbitration proceeding shall be conclusive and binding upon each Party. Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. The prevailing Party shall be entitled to recover reasonable attorneys' fees and court costs in any court proceeding relating to the enforcement or collection of any award or judgment rendered by the arbitration panel under this agreement. |

| | |
| (h) | All deadlines specified herein may be extended by mutual written agreement of the Parties. The procedures specified herein shall be the sole and exclusive procedures for the resolution of disputes between the parties arising out of or relating to this Agreement; provided, however, that a Party may seek a preliminary injunction or other preliminary judicial relief if in its judgment such action is necessary to avoid irreparable damage. Despite such action, the Parties will continue to participate in good faith in the procedures specified herein. All applicable statutes of limitation, including, without limitation, contractual limitation periods provided for in this Agreement, shall be tolled while the procedures specified in this Section are pending. The Parties will take all actions, if any, necessary to effectuate the tolling of any applicable statutes of limitation. |

4.2 Continued Performance. Each Party agrees to continue to perform its obligations under this Agreement while any dispute is being resolved, unless and until: (a) such obligations are terminated by the termination or expiration of this Agreement; or (b) otherwise ordered pursuant to a ruling by the arbitration panel, or the issuance of a temporary restraining order or other preliminary injunctive relief.
