Business and PropertiesGeneralWe are an independent retail energy services company founded in 1999 and now organized as a Delaware corporation that providesresidential and commercial customers with an alternative choice for their natural gas and electricity in competitive markets across theUnited States. We purchase our natural gas and electricity supply from a variety of wholesale providers and bill our customers monthlyfor the delivery of electricity and natural gas based on their consumption at either a fixed or variable price. Electricity and natural gasare 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 withmarket counterparties and independent system operators ("ISOs") and supply electricity to residential and commercialconsumers pursuant to fixed-price and variable-price contracts. For the years ended December 31, 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 withmarket counterparties and supply natural gas to residential and commercial consumers pursuant to fixed-price and variable-pricecontracts. For the years ended December 31, 2018, 2017 and 2016, approximately 14%, 18% and 24%, respectively, of ourrevenues were derived from the sale of natural gas. Our OperationsAs of December 31, 2018, we operated in 94 utility service territories across 19 states and the District of Columbia and hadapproximately 908,000 RCEs. An RCE, or residential customer equivalent, is an industry standard measure of natural gas or electricityusage with each RCE representing annual consumption of 100 MMBtu of natural gas or 10 MWh of electricity. We serve natural gascustomers 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 Columbiausing 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 brandsthrough 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 OfferingsFixed and variable-price contractsWe offer a variety of fixed-price and variable-price service options to our natural gas and electricity customers. Under our fixed-priceservice options, our customers purchase natural gas and electricity at a fixed price over the life of the customer contract, which providesour customers with protection against increases in natural gas and electricity prices. Our fixed-price contracts typically have a term ofone to two years for residential customers and up to three years for commercial customers, and most provide for an early terminationfee in the event that the customer terminates service prior to the expiration of the contract term. In a typical market, we offer fixed-priceelectricity plans for 6, 12 and 24 months and fixed-price natural gas plans from 12 to 24 months, which may come with or without amonthly service fee and/or a termination fee. Our variable-price service options carry a month-to-month term and are priced based onour forecasts of underlying commodity prices and other market factors,5 Table of Contentsincluding the competitive landscape in the market and the regulatory environment, and may also include a monthly service fee. We alsooffer variable-price natural gas and electricity plans that offer an introductory fixed price that is generally applied for a certain numberof billing cycles, typically two billing cycles in our current markets, then switches to a variable price based on market conditions. Ourvariable 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 19% were variable-price.The fixed/variable splits of our RCEs were as follows as of December 31, 2018:Green products and renewable energy creditsWe offer renewable and carbon neutral (“green”) products in certain markets. Green energy products are a growing market opportunityand typically provide increased unit margins as a result of improved customer satisfaction and less competition. Renewable electricityproducts allow customers to choose electricity sourced from wind, solar, hydroelectric and biofuel sources, through the purchase ofrenewable energy credits (“RECs”). Carbon neutral natural gas products give customers the option to reduce or eliminate the carbonfootprint associated with their energy usage through the purchase of carbon offset credits. These products typically provide for fixed orvariable prices and generally follow the terms of our other products with the added benefit of carbon reduction and reducedenvironmental impact. We currently offer renewable electricity in all of our electricity markets and carbon neutral natural gas in severalof 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 individualstate renewable portfolio standards. We forecast the price for the required RECs at the end of each month and incorporate this costcomponent into our customer pricing models.Customer Acquisition and RetentionOur customer acquisition strategy consists of customer growth obtained through traditional sales channels complemented by customerand business acquisitions. We make decisions on how best to deploy capital based on a variety of factors, including cost to acquirecustomers, availability of opportunities and our view of attractive commodity pricing in particular regions.6 Table of ContentsOrganic GrowthWe use organic sales strategies to both maintain and grow our customer base by offering competitive pricing, price certainty, and/orgreen product offerings. We manage growth on a market-by-market basis by developing price curves in each of the markets we serveand comparing the market prices to the price offered by the local regulated utility. We then determine if there is an opportunity in aparticular market based on our ability to create a competitive product on economic terms that provides customer value and satisfies ourprofitability objectives. The attractiveness of a product from a consumer’s standpoint is based on a variety of factors, including overallpricing, price stability, contract term, sources of generation and environmental impact and whether or not the contract provides fortermination and other fees. Product pricing is also based on 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.We identify and acquire customers through a variety of sales channels, including our inbound customer care call center, outboundcalling, online marketing, opt-in web-based leads, email, direct mail, door-to-door sales, affinity programs, direct sales, brokers andconsultants. For residential customers, we primarily use indirect sales brokers, web based solicitation, door-to-door sales, outboundcalling, and other methods. For 2018, the largest channels were door-to-door sales, web-based, and outbound telemarketing. For C&Icustomers, which are typically larger and have greater natural gas and electricity requirements, we typically use brokers or directmarketing to obtain these customers. At December 31, 2018, our customer base was 55% residential and 45% C&I customers. In oursales practices, we typically employ multiple vendors under short-term contracts and have not entered into any exclusive marketingarrangements with sales vendors. Our marketing team continuously evaluates the effectiveness of each customer acquisition channeland makes adjustments in order to achieve targeted growth and manage customer acquisition costs. We attempt to maintain adisciplined approach to recovery of our customer acquisition costs within defined periods.AcquisitionsWe actively monitor acquisition opportunities that may arise in the domestic acquisition market, and seek toacquire both portfolios of customers as well as retail energy companies utilizing some combination of cash and borrowings under ourSenior Credit Facility, the issuance of common or preferred stock, or other financing arrangements. Historically, our customeracquisition strategy has been executed using both third parties and through affiliated relationships. See “—Relationship with ourFounder and Majority Shareholder” for a discussion of affiliate relationships.The following table provides a summary of our acquisitions over the past five years:7 Table of Contents Company / PortfolioDate CompletedRCEsSegmentAcquisition Source Customer PortfolioFebruary 201512,500ElectricityThird Party CenStar Energy Corp.July 201565,000Natural GasElectricityThird Party Oasis Power Holdings, LLCJuly 201540,000Natural GasElectricityAffiliate Customer PortfolioSeptember 20159,500Natural GasThird Party Provider Companies (1)August 2016121,000ElectricityThird Party Major Energy Companies (2)August 2016220,000Natural GasElectricityAffiliate Perigee Energy, LLCApril 201717,000Natural GasElectricityAffiliate Verde Companies (3)July 2017145,000ElectricityThird Party Customer Portfolio (4)October 2017 (4)44,000ElectricityThird Party HIKO Energy, LLCMarch 201829,000Natural GasElectricityThird Party Customer Portfolio (5)(5)35,000Natural GasElectricityAffiliate Customer Portfolio (6)(6)60,000Natural Gas ElectricityThird Party(1)Included Electricity Maine, LLC, Electricity N.H., LLC, Provider Power Mass, LLC (collectively, the “Provider Companies”).(2)Included Major Energy Services, LLC, Major Energy Electric Services, LLC, and Respond Power, LLC (collectively, the “Major Energy Companies”).(3)Included Verde Energy USA, Inc.; Verde Energy USA Commodities, LLC; Verde Energy USA Connecticut, LLC; Verde Energy USA DC, LLC; Verde Energy USA Illinois,LLC; Verde Energy USA Maryland, LLC; Verde Energy USA Massachusetts, LLC; Verde Energy USA New Jersey, LLC; Verde Energy USA New York, LLC; Verde EnergyUSA Ohio, LLC; Verde Energy USA Pennsylvania, LLC; Verde Energy USA Texas Holdings, LLC; Verde Energy USA Trading, LLC; and Verde Energy Solutions, LLC(collectively, the “Verde Companies”).(4)Includes customers transferred from April 2017 through October 2017 from the original owner of Perigee.(5)Includes customers transferred from April 2018 through December 2018.(6)We began to transfer customers we acquired from Starion Energy in December 2018 and will continue to transfer during 2019.Please see and Item 9B. “Other Information” and Note 4 "Acquisitions" in the notes to our consolidated financial statements for a moredetailed description of these acquisitions, including the purchase price, the source of funds and financing arrangements with ourFounder and/or NG&E. Please see “Risk Factors" for a discussion of risks related to our acquisition strategy and ability to finance suchtransactions.Retaining customers and maximizing customer lifetime valueFollowing the acquisition of a customer, we devote significant attention to customer retention. We have developed a disciplined renewalcommunication process, which is designed to effectively reach our customers prior to the end of the contract term, and employ a teamdedicated to managing this renewal communications process. Customers are contacted in each utility prior to the expiration of thecustomer's contract. We may contact the customer through additional channels such as outbound calls or email.We also apply a proprietary evaluation and segmentation process to optimize value to both us and the customer. We analyze historicalusage, attrition rates and consumer behaviors to specifically tailor competitive products that aim to maximize the total expected returnfrom energy sales to a specific customer, which we refer to as customer lifetime value.Investment in ESMIn 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 ofDecember 31, 2018, we have contributed 156.4 million Japanese Yen, or $1.48 Table of Contentsmillion, for a 20% ownership interest in ESM. As of December 31, 2018, ESM has approximately 119,000 customers, which arecurrently excluded from our count of RCEs.Commodity SupplyWe 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 riskmanagement policies. We procure our natural gas and electricity requirements at various trading hubs, city gates and load zones. Whenwe 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 ISOfor delivery. Alternatively, we may use physical products to hedge our electricity exposure rather than buying physical electricity in theday-ahead market from the ISO. During the year ended December 31, 2018, we transacted physical and financial settlement ofelectricity 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 ISOswill 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 subjectto fluctuations based on weather and other market conditions. Many of the utilities we serve also allocate natural gas transportation andstorage 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 aretoo small compared to the much larger bulk transaction volumes required for trades in the wholesale market or it is not economicallyfeasible to do so.We periodically adjust our portfolio of purchase/sale contracts in the wholesale natural gas market based upon continual analysis of ourforecasted load requirements. Natural gas is then delivered to the local regulated utility city-gate or other specified delivery pointswhere the local regulated utility takes control of the natural gas and delivers it to individual customer locations. Additionally, we hedgeour natural gas price exposure with financial products. During the year ended December 31, 2018, we transacted physical and financialsettlement 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 ourthird-party energy suppliers, we have certain contracted credit lines, within which we are able to purchase energy supply from thesecounterparties. If we desire to purchase supply beyond these credit limits, we are required to post collateral in the form of either cash orletters of credit. As we begin to approach the limits of our credit line with one supplier, we may purchase energy supply from anothersupplier and sell that supply to the original counterparty in order to reduce our net position with that counterparty and open upadditional credit to procure supply in the future. Our sales of gas pursuant to these activities also enable us to optimize our credit lineswith third-party energy suppliers by decreasing our net buy position with those suppliers.Asset OptimizationPart of our business includes asset optimization activities in which we identify opportunities in the wholesale natural gas markets inconjunction with our retail procurement and hedging activities. Many of the competitive pipeline choice programs in which weparticipate require us and other retail energy suppliers to take assignment of and manage natural gas transportation and storage assetsupstream of their respective city-gate delivery points. In our allocated storage assets, we are obligated to buy and inject gas in thesummer season (April through October) and sell and withdraw gas during the winter season (November through March). Theseinjection and purchase obligations require us to take a seasonal long position in natural gas. Our asset optimization group determines9 Table of Contentswhether market conditions justify hedging these long positions through additional derivative transactions. We also contract with thirdparties for transportation and storage capacity in the wholesale market and are responsible for reservation and demand chargesattributable to both our allocated and third-party contracted transportation and storage assets. Our asset optimization group utilizes theseallocated and third-party transportation and storage assets in a variety of ways to either improve profitability or optimize supply-sidecounterparty credit lines.We frequently enter into spot market transactions in which we purchase and sell natural gas at the same point or we purchase naturalgas at one location and ship it using our pipeline capacity for sale at another location, if we are able to capture a margin. We view thesespot market transactions as low risk because we enter into the buy and sell transactions on a back-to-back basis. We also act as anintermediary for market participants who need assistance with short-term procurement requirements. Consumers and suppliers contactus 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 ourcontacts in the wholesale market to source the requested supply and capture a margin in these transactions.Our risk policies require that optimization activities be limited to back-to-back purchase and sale transactions, or open positions subjectto aggregate net open position limits, which are not held for a period longer than two months. Furthermore, all additional capacityprocured outside of a utility allocation of retail assets must be approved by a risk committee. Hedges of our firm transportationobligations are limited to two years or less and hedging of interruptible capacity is prohibited.Risk ManagementWe operate under a set of corporate risk policies and procedures relating to the purchase and sale of electricity and natural gas, generalrisk management and credit and collections functions. Our in-house energy supply team is responsible for managing our commoditypositions (including energy, capacity, transmission, renewable energy, and resource adequacy requirements) within our riskmanagement policies. We attempt to increase the predictability of cash flows by following our hedging strategies.Our risk committee has control and authority over all of our risk management activities. The risk committee establishes and oversees theexecution of our credit risk management policy and our commodity risk policy. The risk management policies are reviewed at leastannually and the risk committee typically meets quarterly to assure that we have followed its policies. The risk committee also seeks toensure the application of our risk management policies to new products that we may offer. The risk committee is comprised of ourChief Executive Officer and our Chief Financial Officer, who meet on a regular basis to review the status of the risk managementactivities and positions. Our risk team reports directly to our Chief Financial Officer and their compensation is unrelated to tradingactivity. Commodity positions are typically reviewed and updated daily based on information from our customer databases and pricinginformation sources. The risk policy sets volumetric limits on intra-day and end of day long and short positions in natural gas andelectricity. With respect to specific hedges, we have established and approved a formal delegation of authority specifying each trader'sauthorized 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 delegatedtransaction limits. A discussion of the various risks we face in our risk management activities is as follows:Commodity Price and Volumetric RiskBecause our contracts require that we deliver full natural gas or electricity requirements to 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 customervolumetric needs. In buying or selling excess volumes, we may be exposed to commodity price volatility. In order to address thepotential volumetric variability of our monthly deliveries for fixed-price customers, we implement various hedging strategies to attemptto mitigate our exposure. Our commodity risk management strategy is designed to hedge substantially all of our forecasted volumes on our fixed-price customercontracts, as well as a portion of the near-term volumes on our variable-price customer10 Table of Contentscontracts. We use both physical and financial products to hedge our fixed-price exposure. The efficacy of our risk managementprogram may be adversely impacted by unanticipated events and costs that we are not able to effectively hedge, including abnormalcustomer attrition and consumption, certain variable costs associated with electricity grid reliability, pricing differences in the localmarkets for local delivery of commodities, unanticipated events that impact supply and demand, such as extreme weather, and abruptchanges 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 customervolumes as a basis for our forecasted volumes and mitigate the risk of seasonal volume fluctuation for some customers by purchasingexcess fixed-price hedges within our volumetric tolerances. Should seasonal demand exceed our weather-normalized projections, wemay experience a negative impact on our financial results.From time to time, we also take further measures to reduce price risk and optimize our returns by: (i) maximizing the use of natural gasstorage in our daily balancing market areas in order to give us the flexibility to offset volumetric variability arising from changes inwinter demand; (ii) entering into daily swing contracts in our daily balancing markets over the winter months to enable us to increase ordecrease daily volumes if demand increases or decreases; and (iii) purchasing out-of-the-money call options for contract periods withthe highest seasonal volumetric risk to protect against steeply rising prices if our customer demands exceed our forecast. Beinggeographically diversified in our delivery areas also permits us, from time to time, to employ assets not being used in one area to otherareas, thereby mitigating potential increased costs for natural gas that we otherwise may have had to acquire at higher prices to meetincreased 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 aresettled using the NYMEX Exchange’s published settlement price at their maturity.Basis RiskWe are exposed to basis risk in our operations when the commodities we hedge are sold at different delivery points from the exposurewe are seeking to hedge. For example, if we hedge our natural gas commodity price with Chicago basis but physical supply must bedelivered to the individual delivery points of specific utility systems around the Chicago metropolitan area, we are exposed to the riskthat prices may differ between the Chicago delivery point and the individual utility system delivery points. These differences can besignificant from time to time, particularly during extreme, unforecasted cold weather conditions. Similarly, in certain of our electricitymarkets, customers pay the load zone price for electricity, so if we purchase supply to be delivered at a hub, we may have basis riskbetween the hub and the load zone electricity prices due to local congestion that is not reflected in the hub price. We attempt to hedgebasis risk where possible, but hedging instruments are occasionally not economically feasible or available in the smaller quantities thatwe require.Customer Credit RiskOur credit risk management policies are designed to limit customer credit exposure. Credit risk is managed through participation inpurchase of receivables ("POR") programs in utility service territories where such programs are available. In these markets, we monitorthe 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 andrespond to any deteriorating trends. In non-POR markets, we assess the creditworthiness of new applicants, monitor customer paymentactivities and administer an active collection program. Using risk models, past credit experience and different levels of exposure in eachof the markets, we monitor our receivable aging, bad debt forecasts and actual bad debt expenses and continually adjust as necessary.11 Table of ContentsIn territories where POR programs have been established, the local regulated utility purchases our receivables, and then becomesresponsible for billing and collecting payment from the customer. In return for their assumption of risk, we receive slightly discountedproceeds on the receivables sold. POR programs result in substantially all of our credit risk being linked to the applicable utility and notto our end-use customer in these territories. For the year ended December 31, 2018, approximately 66% of our retail revenues werederived from territories in which substantially all of our credit risk was directly linked to local regulated utility companies, all of whichhad investment grade ratings. During the same period, we paid these local regulated utilities a weighted average discount ofapproximately 1.0% of total revenues for customer credit risk. In certain of the POR markets in which we operate, the utilities limit theircollections exposure by retaining the ability to transfer a delinquent account back to us for collection when collections are past due for aspecified period. If our subsequent collection efforts are unsuccessful, we return the account to the local regulated utility for terminationof service. Under these service programs, we are exposed to credit risk related to payment for services rendered during the timebetween when the customer is transferred to us by the local regulated utility and the time we return the customer to the utility fortermination of service, which is generally one to two billing periods. We may also realize a loss on fixed-price customers in thisscenario 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 customercredit risk through a formal credit review and manage residential customer credit risk through a variety of procedures, which mayinclude credit score screening, deposits and disconnection for non-payment. We 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 andgeneral economic conditions in the markets that we serve. Our bad debt expense for the year ended December 31, 2018 was $10.1million, 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 endedDecember 31, 2018.We do not have high concentrations of sales volumes to individual customers. For the year ended December 31, 2018, our largestcustomer accounted for less than 1% of total retail energy sales volume.Counterparty Credit Risk in Wholesale MarketsWe do not independently produce natural gas and electricity and depend upon third parties for our supply, which exposes us towholesale counterparty credit risk in our retail and asset optimization activities. If the counterparties to our supply contracts are unableto perform their obligations, we may suffer losses, including those that occur as a result of being unable to secure replacement suppliesof natural gas or electricity on a timely or cost-effective basis or at all. At December 31, 2018, approximately $4.1 million of our totalexposure of $22.7 million was either with a non-investment grade counterparty or otherwise not secured with collateral or a guarantee.Operational RiskAs with all companies, we are at risk from cyber-attacks (breaches, unauthorized access, misuse, computer viruses, or other maliciouscode or other events) that could materially adversely affect our business, or otherwise cause interruptions or malfunctions in ouroperations.We mitigate these risks through multiple layers of security controls including policy, hardware, and software security solutions. We alsohave engaged third parties to assist with both external and internal vulnerability scans and continually enhance awareness throughemployee education and accountability. As of December 31, 2018, we have not experienced any material loss related to cyber-attacksor other information security breaches.Relationship with our Founder and Majority Shareholder12 Table of ContentsWe have historically leveraged our relationship with affiliates of our founder, chairman and majority shareholder, W. Keith Maxwell III(our "Founder"), to execute our strategy, including sourcing acquisitions, financing, and operations support. Our Founder ownsNational Gas & Electric, LLC, an affiliate of the Company (“NG&E”), which was formed for the purpose of purchasing retail energycompanies and retail customer books that may ultimately be resold to the Company. This relationship has afforded us access toopportunities that may not have otherwise been available to us due to our size and availability of capital.We may engage in additional transactions with NG&E in the future and expect that any such transactions would be funded by acombination of cash, subordinated debt, or the issuance of Class A or Class B common stock. Actual consideration paid for the assetswould depend, among other things, on our capital structure and liquidity at the time of any transaction. Although we believe ourFounder would be incentivized to offer us additional acquisition opportunities, he and his affiliates are under no obligation to do so, andwe are under no obligation to buy assets from them. Any acquisition activity involving NG&E or any other affiliate of our Founder willbe subject to negotiation and approval by a special committee of our Board of Directors consisting solely of independent directors.Please see “Risk Factors" related to acquisitions and transactions with our affiliates.Prior to April 2018, we maintained a Master Service Agreement (the “Master Service Agreement”) with an affiliated company whollyowned by our Founder. Under this agreement, we were provided operational support services such as: enrollment and renewaltransaction services; customer billing and transaction services; electronic payment processing services; customer services andinformation technology infrastructure and application support services (collectively, the "Services"). We paid our affiliate a monthly feeconsisting 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 Statementsand Supplementary Data, Note 15 "Transactions with Affiliates."CompetitionThe markets in which we operate are highly competitive. In markets that are open to competitive choice of retail energy suppliers, ourprimary competition comes from the incumbent utility and other independent retail energy companies. In the electricity sector, thesecompetitors include larger, well-capitalized energy retailers such as 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 theelectricity sector that are focused exclusively on certain markets. Each market has a different group of local retail energy providers. Inthe natural gas sector, our national competitors are primarily Direct Energy and Constellation Energy. Our national competitorsgenerally 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 ourmarkets varies. In well-established markets in the Northeast and Texas we have hundreds of competitors, while in others thecompetition is limited to several participants. Markets that offer POR programs are generally more competitive than those markets inwhich retail energy providers bear customer credit risk.Our ability to compete depends on our ability to convince customers to switch to our products and services, and our ability to offerproducts at attractive prices. Many local regulated utilities and their affiliates may possess the advantages of name recognition, longeroperating histories, long-standing relationships with their customers and access to financial and other resources, which could pose acompetitive challenge to us. As a result of these advantages, many customers of these local regulated utilities may decide to stay withtheir longtime energy provider if they have been satisfied with their service in the past. In addition, competitors may choose to offermore attractive short-term pricing to increase their market share.Seasonality of Our Business13 Table of ContentsOur 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 andelectricity and affect the prices of energy commodities; and (iv) variability in market prices for natural gas and electricity. These factorscan have material short-term impacts on monthly and quarterly operating results, which may be misleading when considered outside ofthe 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 oursuppliers for accounts payable versus when we collect from our customers on accounts receivable. We typically pay our suppliers forpurchases of natural gas on a monthly basis and electricity on a weekly basis. However, it takes approximately two months from thetime we deliver the electricity or natural gas to our customers before we collect from our customers on accounts receivable attributableto 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 highdegree of seasonality in our cash flows and income earned throughout the year as a result of the high concentration of heating load inthe winter months. We utilize a considerable amount of cash from operations and borrowing capacity to fund working capital, whichincludes inventory purchases from April through October each year. We sell our natural gas inventory during the months of Novemberthrough March of each year. We expect that the significant seasonality impacts to our cash flows and income will continue in futureperiods. Regulatory EnvironmentWe operate in the highly regulated natural gas and electricity retail sales industry in all of our respective jurisdictions, and must complywith the legislation and regulations in these jurisdictions in order to maintain our licenses to operate. We must also comply to obtain thenecessary 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 retailelectricity and gas suppliers. There is potential for changes to state legislation and regulatory measures addressing licensingrequirements that may impact our business model in the applicable jurisdiction. In addition, as further discussed below, our marketingactivities and customer enrollment procedures are subject to rules and regulations at the state and federal levels, and failure to complywith requirements imposed by federal and state regulatory authorities could impact our licensing in a particular market.In February 2016, the New York State Public Service Commission ("NYPSC") issued an order (the "Reset Order") resetting retail energymarkets that, among other things, would have limited the types of competitive products that energy service companies ("ESCOs"), suchas 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 thecustomer will pay no more than what the customer would pay as a full service utility customer, or (ii) an electricity product that is atleast 30% derived from specific renewable sources either in the State of New York or in adjacent market areas. In July 2016, most ofthe 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 rulingoverturning portions of the Reset Order because the NYPSC did not follow the proper process in issuing the Reset Order. However, thecourt also determined that the NYPSC has authority to set ESCO rates and take other action consistent with the Resetting Order as longas the proper administrative process is followed. The NYPSC conducted evidentiary proceedings to determine what the regulatoryframework for ESCOs in New York would be going forward, which concluded in late 2017. There can be no assurance that this processwill result in a commercially reasonable framework for ESCOs to operate in New York. See "Risk Factors—We face risks due toincreasing regulation of the retail energy industry at the state level."14 Table of ContentsIn addition, in connection with the Low-Income Order promulgated by the NYPSC in December of 2016, the New York State SupremeCourt, Appellate Division, Third Department ruled in September 2017 that ESCOs must proceed with returning existing low-incomecustomers to utility service and stop enrolling new low-income customers. The ESCO’s have effectively exhausted their legal remediesto appeal this matter and must now comply with the Low-Income Order. ESCOs may continue serving low income customers if thosecustomers are enrolled in fixed arrangements with guaranteed savings or with value add inclusions (that were entered into prior to theeffective date of the Low-Income Order) or if the ESCO receives a waiver from the NYPSC to provide low-income customers withguaranteed savings. The Company and its subsidiaries have been returning low-income customers to the applicable utilities as theyhave rolled off of their contracts. As of December 31, 2018, remaining low-income customers represent approximately 3% of our totalRCEs 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 whilepreparing 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 atthis 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 andothers alleging unfair or deceptive acts or practices in violation of a consumer protections act, breach of the covenant of good faith andfair 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 possibledamages. 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 customersassociated with certain changes in law or regulatory requirements. For example, on January 22, 2019, the New Jersey Board of PublicUtilities (NJ BPU) sent a cease and desist letter to third party suppliers (TPS) in New Jersey instructing that a TPS may not charge acustomer rate that is higher than the fixed rate applicable during the period for which that rate was fixed. The letter notified TPS thatsuch increases were prohibited and instructed TPS to refund customers amounts charged in excess of the applicable fixed rate. Partieshave challenged the NJ BPU’s letter and it is not clear at this time whether refunds will be required. Similarly, the Connecticut PublicUtilities Regulatory Authority (PURA) recently opened a docket after receiving complaints regarding increases by suppliers to certainfixed-price supplier contracts due to change in law triggers. PURA will consider whether suppliers’ actions constitute unfair anddeceptive 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 itotherwise 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, aresubject to consumer protection regulation including state deceptive trade practices acts, Federal Trade Commission ("FTC") marketingstandards, 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 stateregulators. 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 particularmarket, result in suspension or otherwise limit our ability to conduct marketing activity in certain markets, and potentially lead toprivate actions against us. Moreover, there is potential for changes to legislation and regulatory measures applicable to our marketingmeasures 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 theTCPA. Also, additional restrictions have been placed on wireless15 Table of Contentstelephone numbers making compliance with the TCPA more costly. See “Risk Factors—Risks Related to Our Business and OurIndustry—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 regulatorycompliance perspective and from the risk of such activities drawing class action litigation claims, we and our peers who rely on thesesales channels will find it more difficult than in the past to engage in direct marketing efforts. In response to these risks, we areexperimenting with new technologies, such as a web-based application to process door-to-door sales enrollments with direct input bythe consumer. This application can be accessed using tablets or any smart phone device, which enhances and expands the opportunitiesto market directly to customers.Our participation in natural gas and electricity wholesale markets to procure supply for our retail customers and hedge pricing risk issubject to regulation by the Commodity Futures Trading Commission (the "CFTC"), including regulation pursuant to the Dodd-FrankWall Street Reform and Consumer Protection Act. In order to sell electricity, capacity and ancillary services in the wholesale electricitymarkets, we are required to have market-based rate authorization, also known as “MBR Authorization”, from the Federal EnergyRegulatory Commission ("FERC"). We are required to make status update filings to FERC to disclose any affiliate relationships andquarterly filings to FERC regarding volumes of wholesale electricity sales in order to maintain our MBR Authorization. We are alsorequired to seek prior approval by FERC to the extent any direct or indirect change in control occurs with respect to entities that holdMBR 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 supplyfor our retail customers and hedge pricing risk. Since 1985, FERC has endeavored to make natural gas transportation more accessible tonatural gas buyers and sellers on an open and non-discriminatory basis. FERC’s orders do not attempt to directly regulate natural gasretail sales. As a shipper of natural gas on interstate pipelines, we are subject to those interstate pipelines' tariff requirements and FERCregulations 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 interruptibletransportation service on interstate pipelines, and we cannot predict what future action FERC will take. We do not believe, however, thatany regulatory changes will affect us in a way that materially differs from the way they will affect other natural gas marketers and localregulated utilities with which we compete.In December 2007, FERC issued Order 704, a final rule on the annual natural gas transaction reporting requirements, as amended bysubsequent orders on rehearing. Under Order 704, wholesale buyers and sellers of more than 2.2 million MMBtus of physical naturalgas 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 whichindividual transactions should be reported based on the guidance of Order 704. Order 704 also requires market participants to indicatewhether they report prices to any index publishers, and if so, whether their reporting complies with FERC’s policy statement on pricereporting. As a wholesale buyer and seller of natural gas, we are subject to the reporting requirements of Order 704.EmployeesWe employed 176 people as of December 31, 2018, none of which were subject to any collective bargaining agreements. We have notexperienced any strikes or work stoppages and consider our relations with our employees to be satisfactory. We also utilize the servicesof independent contractors and vendors to perform various services.16 Table of ContentsFacilitiesOur corporate headquarters is located in Houston, Texas, and we also maintain an office in Orangeburg, New York. We believe that ourfacilities are adequate for our current operations. We share our corporate headquarters with certain of our affiliates, one of which is thelessee under the lease agreement covering these facilities, paying the entire lease payment on behalf of all affiliates. We reimburse thisaffiliate for our share of the leased space.17 Table of ContentsAvailable InformationOur principal executive offices are located at 12140 Wickchester Ln., Suite 100, Houston, Texas 77079, and our telephone number is(713) 600-2600. Our website is located at www.sparkenergy.com. We make available our periodic reports and other information filedwith or furnished to the Securities and Exchange Commission (the “SEC”), including our annual reports on Form 10-K, our quarterlyreports on Form 10-Q, our current reports on Form 8-K, and all amendments to those reports, free of charge through our website, assoon as reasonably practicable after those reports and other information are electronically filed with or furnished to the SEC. Anymaterials filed with the SEC may be read and copied at the SEC’s website at www.sec.gov.18 Table of ContentsItem 1A. Risk FactorsYou should carefully consider the risks described below together with the other information contained in this Annual Report on Form10-K. If any of the risks below were to occur, our business, financial condition, cash flows, results of operation and ability to paydividends on our Class A common stock and Series A Preferred Stock could be adversely impacted, and the price of the Class Acommon stock and Series A Preferred Stock could decline and you could lose your investment.Risks Related to Our Business and Our IndustryWe 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 marketprices 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:—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 inenvironmental 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 thekinds 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 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 energycommodities. Generally, on most utility systems, demand for natural gas peaks in the winter and demand for electricity peaks in thesummer. Typically, when winters are warmer or summers are cooler, demand for energy is lower than expected, resulting in less naturalgas and electricity consumption than forecasted. When demand is below anticipated levels due to weather patterns, we may be forced tosell 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 electricityagainst 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 toaccurately anticipate demand due to fluctuations in weather or to effectively manage our supply in response to a fluctuating commodityprice environment.19 Table of ContentsOur risk management policies and hedging procedures may not mitigate risk as planned, and we may fail to fully or effectively hedgeour commodity supply and price risk.To provide energy to our customers, we purchase commodities in the wholesale energy markets, which are often highly volatile. Ourcommodity risk management strategy is designed to hedge substantially all of our forecasted volumes on our fixed-price customercontracts, as well as a portion of the near-term volumes on our variable-price customer contracts. We use both physical and financialproducts to hedge our exposure. The efficacy of our risk management program may be adversely impacted by unanticipated events andcosts that we are not able to effectively hedge, including abnormal customer attrition and consumption, certain variable costs associatedwith electricity grid reliability, pricing differences in the local markets for local delivery of commodities, unanticipated events thatimpact supply and demand, such as extreme weather, and abrupt changes in the markets for, or availability or cost of, financialinstruments 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 exposurewe are seeking to hedge. For example, if we hedge our natural gas commodity price with Chicago basis but physical supply must bedelivered to the individual delivery points of specific utility systems around the Chicago metropolitan area, we are exposed to basis riskbetween 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 theload 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 loadzone electricity prices due to local congestion that is not reflected in the hub price. We attempt to hedge basis risk where possible, buthedging 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 ofthe grid. We attempt to estimate such amounts but they are difficult to estimate because they are charged in arrears by the ISOs and aresubject to fluctuations based on weather and other market conditions. We may be unable to fully pass the higher cost of ancillaryreserves and reliability services through to our customers, and increases in the cost of these ancillary reserves and reliability servicescould 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 competitivemarket operations. We are required to fill our allocated storage capacity with natural gas, which creates commodity supply and pricerisk. Sometimes we cannot hedge the volumes associated with these assets because they are too small compared to the much larger bulktransaction volumes required for trades in the wholesale market or it is not economically feasible to do so. In some regulatory programsor under some contracts, this capacity may be subject to recall by the utilities, which could have the effect of us being required toaccess the spot market to cover such 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 toour business could be implemented in the future. To the extent that the competitive restructuring of retail electricity and natural gasmarkets is reversed, altered or discontinued, such changes could have a detrimental impact on our business and overall financialcondition.20 Table of ContentsSome states are beginning to increase their regulation of their retail electricity and natural gas markets in an effort to eliminate deceptivemarketing practices. For example, in 2015 the Connecticut Legislature passed legislation providing that licensed electric suppliers inConnecticut could no longer offer variable rate products.Additionally, the NYPSC launched efforts in 2016 to limit the types of competitive products that ESCOs, such as us, can offer in NewYork. The NYPSC issued an order (the "Reset Order") requiring that all new customer enrollments or expiring agreements for massmarket (residential and certain small commercial) customers must enroll or re-enroll in a contract that offers either: (i) a guarantee thatthe customer will pay no more than what the customer would pay as a full service utility customer, or (ii) an electricity product that is atleast 30% derived from specific renewable sources either in the State of New York or in adjacent market areas. Most of the originalReset Order was vacated by a New York state court in July 2016. However, the ESCOs lost an appeal on the matter of whether theNYPSC has jurisdiction over ESCO pricing of products. Currently, ESCOs and the NYPSC are involved in evidentiary proceedings thatare addressing, among other things, whether the NYPSC has sufficient cause to implement regulatory changes similar to those proposedin the Reset Order. In the event that all or significant components of the Reset Order are implemented, ESCOs, including us, could beobligated to, among other things, drop customers to the utility or seek affirmative consent from fixed and variable rate customers uponrenewal, which may be very difficult to obtain. As of December 31, 2018, approximately 16% of our customers on an RCE basis werelocated in New York.The NYPSC has also implemented a low-income order that requires ESCOs to return existing low-income customers to utility serviceand stop enrolling new low-income customers unless customers are enrolled in fixed arrangements with guaranteed savings or withvalue add inclusions (that were entered into prior to the effective date of the low-income order) or if the ESCO receives a waiver fromthe NYPSC to provide low-income customers with guaranteed savings. As a result of the low-income order, we have been droppinglow-income customers back to the applicable utilities as they have rolled off of their contracts. As of December 31, 2018, remaininglow-income customers represent approximately 3% of our total RCEs in New York and 0.5% of our RCEs overall. There can be noassurance that the NYPSC or state regulatory agencies to which we are subject will not continue trying to implement restrictive anti-competitive regulations on us.On October 15, 2018, the Attorney General for the Commonwealth of Massachusetts filed suit against certain other ESCOs allegingunfair 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, theCommonwealth filed for injunctive relief seeking to attach purchase of receivables program revenues owed to the ESCO as possibledamages. There can be no assurance that the Commonwealth will not pursue similar claims against other ESCOs or that other stateregulatory agencies to which we are subject will not continue trying to implement restrictive anti-competitive regulations on us andother ESCOs.Recently, certain state commissions have begun efforts to restrict the ability of retail suppliers to “pass through” costs to customersassociated with certain changes in law or regulatory requirements. For example, on January 22, 2019, the New Jersey Board of PublicUtilities ("NJ BPU") sent a cease and desist letter to third party suppliers ("TPS") in New Jersey instructing that a TPS may not charge acustomer rate that is higher than the fixed rate applicable during the period for which that rate was fixed. The letter notified TPS thatsuch increases were prohibited and instructed TPS to refund customers amounts charged in excess of the applicable fixed rate. Partieshave challenged the NJ BPU’s letter and it is not clear at this time whether refunds will be required. Similarly, the Connecticut PublicUtilities Regulatory Authority ("PURA") recently opened a docket after receiving complaints regarding increases by suppliers to certainfixed-price supplier contracts due to change in law triggers. PURA will consider whether suppliers’ actions constitute unfair anddeceptive 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 itotherwise would pass on to customers under its change in law provisions and potentially provide refunds to certain customers.21 Table of ContentsThe 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, manyelectricity markets have rate caps, and changes to these rate caps by regulators can impact future price exposure. Similarly, regulatorychanges can result in new fees or charges that may not have been anticipated when existing retail contracts were drafted, which cancreate 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.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 underthe 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 ofmobile messaging to communicate with our customers has created new issues of application of the TCPA to these communications. In2015, 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 theadverse effects of having to defend and ultimately suffer liability in a class action lawsuit related to such non-compliance.We are also subject to liability under the TCPA for actions of our third party vendors who are engaging in outbound telemarketingefforts on our behalf. The issue of vicarious liability for the actions of third parties in violation of the TCPA remains unclear and hasbeen the subject of conflicting precedent in the federal appellate courts. There can be no assurance that we may be subject to significantdamages as a result of a class action lawsuit for actions of our vendors that we may not be able to control.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 lawsuits, claims and regulatory proceeds arising in the ordinary course of our business from time to time, includingseveral purported class action lawsuits involving sales practices or TCPA claims and breach of contract claims. These are in variousstages and are subject to substantial uncertainties concerning the outcome.A negative outcome for any of these matters could result in significant damages. Litigation may also negatively impact us by requiringus to pay substantial settlements, increasing our legal costs, diverting management attention from other business issues or harming ourreputation with customers.For additional information regarding the nature and status of certain proceedings, see Note 14 "Commitment and Contingencies" to theaudited 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 arenewal of a license, or our license could be adversely conditioned or modified (e.g., by increased bond posting obligations).We may be subject to risks in connection with acquisitions, which could cause us to fail to realize many of the anticipated benefits ofsuch acquisitions.We have grown our business in part through strategic acquisition opportunities from third parties and from affiliates of our majorityshareholder and may continue to do so in the future. Achieving the anticipated benefits of these transactions depends in part upon ourability to identify accretive acquisition targets, accurately assess the benefits22 Table of Contentsand risks of the acquisition prior to undertaking it, and the ability to integrate the acquired businesses in an efficient and effectivemanner. 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 estimatinganticipated cash flow and accretive value, evaluating potential regulatory challenges, retaining customers and assuming liabilities. Theaccuracy of these 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. Thedifficulties of integrating acquisitions can include, among other things:–coordinating geographically separate organizations and addressing possible differences in corporate cultures and managementphilosophies;–dedicating significant management resources to the integration of the acquisition, which may temporarily distract management'sattention 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;–managing different and competing brands and retail strategies in the same markets;–coordinating customer information and billing systems and determining how to optimize those systems on a consolidated level;–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 breachesof representations, warranties and covenants, tax matters, and litigation proceedings. We generally obtain security to provide assurancesthat the counterparty could perform its indemnification obligations, which may be in the form of escrow accounts, payment withholdingor 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 thecounterparty 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 areunable to make acquisitions of portfolios of customers and retail energy companies on commercially reasonable terms.Pursuant to our cash dividend policy, we distribute a significant portion of our cash through regular quarterly dividends, and ourability 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 throughregular quarterly dividends to holders of our Class A common stock and dividends on our Series A Preferred Stock. As such, ourgrowth may not be as fast as that of businesses that reinvest their available cash to expand ongoing operations, and we may have to relyupon external financing sources, including the issuance of debt, equity securities, convertible subordinated notes and borrowings underour Senior Credit Facility and Subordinated Facility. These sources may not be available, and our ability to grow and maintain ourbusiness may be limited.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 newmarkets in a timely manner at reasonable costs, organically or through acquisitions. In order for us to recover expenses incurred inentering 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 and23 Table of Contentsimplementing new product offerings, integrating new customers and employees, and complying with applicable market rules and theinfrastructure for product delivery.Expanding our operations also may require continued development of our operating and financial controls and may place additionalstress on our management and operational resources. We may be unable to manage our growth and development successfully.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 ofour 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 energydelivery networks. These factors can have material short-term impacts on monthly and quarterly operating results, which may bemisleading when considered outside of the context of our annual operating cycle. In addition, our accounts payable and accountsreceivable are impacted by seasonality due to the timing differences between when we pay our suppliers for accounts payable versuswhen we collect from our customers on accounts receivable. We typically pay our suppliers for purchases of natural gas on a monthlybasis and electricity on a weekly basis. However, it takes approximately two months from the time we deliver the electricity or naturalgas to our customers before we collect from our customers on accounts receivable attributable to those supplies. This timing differencecould affect our cash flows, especially during peak cycles in the winter and summer months. Furthermore, as a result of the seasonalityof our business, we may reserve a portion of our excess cash available for distribution in the first and fourth quarters in order to fundour 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 ofour hedging instruments that are not qualifying or not designated as hedges under accounting rules are recognized immediately inearnings. As a result of this accounting treatment, changes in the forward prices of natural gas and electricity cause volatility in ourquarterly 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 ininventory if we choose to hedge the summer-winter spread on our retail allocated storage capacity. We typically purchase natural gasinventory and store it from April to October for withdrawal from November through March. Since a portion of the inventory is used tosatisfy delivery obligations to our fixed-price customers over the winter months, we hedge the associated price risk using derivativecontracts. Any gains or losses associated with settled derivative contracts are reflected in the statement of operations as a component ofretail cost of sales and net asset optimization.We may have difficulty retaining our existing customers or obtaining a sufficient number of new customers, due to competition andfor other reasons.The markets in which we compete are highly competitive, and we may face difficulty retaining our existing customers or obtaining newcustomers due to competition. We encounter significant competition from local regulated utilities or their retail affiliates and traditionaland new retail energy providers. Many of these competitors or potential competitors are larger than us, have access to more significantcapital 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 asignificant decrease in the retail price of natural gas or electricity in order to obtain more favorable prices. Although we generally havea right to collect a termination fee from each customer on a fixed-price contract who terminates their contract early, we may not be ableto collect the termination fees in full or at all. Our variable-price contracts can typically be terminated by our customers at any timewithout penalty. We may be unable to obtain new customers or maintain our existing customers due to competition or otherwise.24 Table of ContentsIncreased collateral requirements in connection with our supply activities may restrict our liquidity.Our contractual agreements with certain local regulated utilities and our supplier counterparties require us to maintain restricted cashbalances or letters of credit as collateral for credit risk or the performance risk associated with the future delivery of natural gas orelectricity. These collateral requirements may increase as we grow our customer base. Collateral requirements will increase based on thevolume or cost of the commodity we purchase in any given month and the amount of capacity or service contracted for with the localregulated utility. Significant changes in market prices also can result in fluctuations in the collateral that local regulated utilities orsuppliers require.The effectiveness of our operations and future growth depend in part on the amount of cash and letters of credit available to enter intoor maintain these contracts. The cost of these arrangements may be affected by changes in credit markets, such as interest rate spreadsin the cost of financing between different levels of credit ratings. These liquidity requirements may be greater than we anticipate or areable to meet.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 customers located in markets that have not implemented POR programs as well as indirect creditrisk in those POR markets that pass collection efforts along to us after a specified non-payment period. For the year endedDecember 31, 2018, customers in non-POR markets represented approximately 34% of our retail revenues. We generally have theability to terminate contracts with customers in the event of non-payment, but in most states in which we operate we cannot disconnecttheir natural gas or electricity service. In POR markets where the local regulated utility has the ability to return non-paying customers tous after specified periods, we may realize a loss for one to two billing periods until we can terminate these customers’ contracts. Wemay also realize a loss on fixed-price customers in this scenario due to the fact that we will have already fully hedged the customer’sexpected commodity usage for the life of the contract and we also remain liable to our suppliers of natural gas and electricity for thecost of our supply commodities. Furthermore, in the Texas market, we are responsible for billing the distribution charges for the localregulated 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 unableto pay their bills when due.Our indebtedness could adversely affect our ability to raise additional capital to fund our operations or pay dividends. It could alsoexpose us to the risk of increased interest rates and limit our ability to react to changes in the economy or our industry as well asimpact our cash available for distribution.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 SeniorCredit 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, thereforereducing or eliminating our ability to pay dividends to holders of our Class A common stock and Series A Preferred Stock, orto 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 makecertain distributions to us, in light of restricted payment and other financial covenants, including requirements to maintaincertain 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 are at variable rates of interest; and—limiting our ability to obtain additional financing for working capital including collateral postings, capital expenditures, debtservice 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, andwe cannot assure that we will be able to negotiate a new credit arrangement on commercially reasonable terms.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 otherimportant 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 naturaldisasters, epidemics, failures in hardware or software, power fluctuations, telecommunications and other similar disruptions. In addition,our information management systems may be vulnerable to computer viruses, incursions by intruders or hackers and cyber terroristsand other similar disruptions. A successful cyber-attack on our information management systems could severely disrupt businessoperations, preventing us from billing and collecting revenues, and could result in significant expenses to investigate and repair securitybreaches or system damage, lead to litigation, fines, other remedial action, heightened regulatory scrutiny, diminished customerconfidence and damage to our reputation. Although we maintain cyber-liability insurance that covers certain damage caused by cyberevents, 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 havesubstantial experience in consumer and energy markets that have undergone regulatory restructuring and have extensive riskmanagement and hedging expertise. We believe their experience is important to our continued success. We do not maintain key lifeinsurance policies for our executive officers. Our key executives may not continue in their present roles and may not be adequatelyreplaced.26 Table of ContentsWe 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 continuedperformance of that vendor under the outsourcing agreement. Our vendor may fail to operate in accordance with the terms of theoutsourcing agreement or a bankruptcy or other event may prevent it from performing under our outsourcing agreement.A large portion of our current customers are concentrated in a limited number of states, making us vulnerable to customerconcentration risks.As of December 31, 2018, approximately 62% of our RCEs were located in five states. Specifically, 16%, 14%, 12%, 11% and 9% ofour customers on an RCE basis were located in NY, MA, PA, CT and ME, respectively. If we are unable to increase our market shareacross other competitive markets or enter into new competitive markets effectively, we may be subject to continued or greater customerconcentration risk. The states that contain a large percentage of our customers could reverse regulatory restructuring or change theregulatory environment in a manner that causes us to be unable to economically operate in that state.Increases in state renewable portfolio standards or an increase in the cost of renewable energy credit and carbon offsets mayadversely impact the price, availability and marketability of our products.Pursuant to state renewable portfolio standards, we must purchase a specified amount of RECs based on the amount of electricity wesell in a state in a year. In addition, we have contracts with certain customers that require us to purchase RECs or carbon offsets. If astate increases its renewable portfolio standards, the demand for RECs within that state will increase and therefore the market price forRECs could increase. We attempt to forecast the price for the required RECs and carbon offsets at the end of each month andincorporate this forecast into our customer pricing models, but the price paid for RECs and carbon offsets may be higher thanforecasted. We may be unable to fully pass the higher cost of RECs through to our customers, and increases in the price of RECs maydecrease our results of operations and affect our ability to compete with other energy retailers that have not contracted with customersto purchase RECs or carbon offsets. Further, a price increase for RECs or carbon offsets may require us to decrease the renewableportion of our energy products, which may result in a loss of customers. A further reduction in benefits received by local regulatedutilities 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.Our access to marketing channels may be contingent upon the viability of our telemarketing and door-to-door agreements with ourvendors.Our vendors are essential to our telemarketing and door-to-door sales activities. Our ability to increase revenues in the future willdepend significantly on our access to high quality vendors. If we are unable to attract new vendors and retain existing vendors toachieve our marketing targets, our growth may be materially reduced. There can be no assurance that competitive conditions will allowthese vendors and their independent contractors to continue to successfully sign up new customers. Further, if our products are notattractive to, or do not generate sufficient revenue for our vendors, we may lose our existing relationships. In addition, the decline inlandlines reduces the number of potential customers that may be reached by our telemarketing efforts and as a result our telemarketingsales channel may become less viable and we may be required to use more door-to-door marketing. Door-to-door marketing iscontinually under scrutiny by state regulators and legislators, which may lead to new rules and regulations that impact our ability to usethese channels.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 orpartially beyond our control, such as violations of our marketing policies and procedures as well as any failure to comply withapplicable laws and regulations. If our vendors engage in marketing practices that are27 Table of Contentsnot in compliance with local laws and regulations, we may be in breach of applicable laws and regulations that may result in regulatoryproceedings, disadvantageous conditioning of our energy retailer license, or the revocation of our energy retailer license. Unauthorizedactivities in connection with sales efforts by agents of our vendors, including calling consumers in violation of the TCPA and predatorydoor-to-door sales tactics and fraudulent misrepresentation could subject us to class action lawsuits against which we will be required todefend. Such defense efforts will be costly and time consuming. In addition, the independent contractors of our vendors may considerus to be their employer and seek compensation.Risks Related to Our Capital StockWe cannot assure you that we will be able to continue paying our targeted quarterly dividend to the holders of our Class A commonstock 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, whichfluctuates 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;—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 thedividends on our Series A Preferred Stock or to pay a specific level of cash dividends to holders of our Class A common stock.The amount of cash available for distribution depends primarily on our cash flow, and is not solely a function of profitability, which isaffected by non-cash items. We may incur other expenses or liabilities during a period that could significantly reduce or eliminate ourcash available for distribution and, in turn, impair our ability to pay dividends to holders of our Class A common stock and Series APreferred Stock during the period. Additionally, the dividends paid on Series A Preferred Stock reduce the amount of cash we haveavailable 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 cashdividends. Any Class A common stock or preferred stock (whether Series A Preferred Stock or a new series of preferred stock) that mayin 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 directorsmay 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 unlessdeclared or set aside for payment by our board of directors. Under Delaware law, cash dividends on capital stock may only be paidfrom “surplus” or, if there is no “surplus,” from the corporation’s net profits for the28 Table of Contentsthen-current or the preceding fiscal year. Unless we operate profitably, our ability to pay cash dividends on the Class A common stockand 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 paydividends on the Series A Preferred Stock when payable, and quarterly dividends on the Class A common stock. Further, even ifadequate surplus is available to pay cash dividends on the Class A common stock and Series A Preferred Stock, we may not havesufficient 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 beunlawful under Delaware law or any other applicable law, or when the terms and provisions of any documents limiting the payment ofdividends prohibit the authorization, payment, declaration or setting aside for payment thereof or would constitute a breach or a defaultunder such document.We are a holding company. Our sole material asset is our equity interest in Spark HoldCo, LLC ("Spark HoldCo") and we areaccordingly dependent upon distributions from Spark HoldCo to pay dividends on the Class A common stock and Series A PreferredStock.We are a holding company and have no material assets other than our equity interest in Spark HoldCo, and have no independent meansof generating revenue. Spark HoldCo or its subsidiaries may be restricted from making distributions to us under applicable law orregulation or under the terms of their financing arrangements, or may otherwise be unable to provide such funds.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 (includingindebtedness outstanding under the Senior Credit Facility). Therefore, if we become bankrupt, liquidate our assets, reorganize or enterinto certain other transactions, assets will be available to pay our obligations with respect to the Series A Preferred Stock only after wehave paid all of our existing and future indebtedness in full. The Class A common stock will only receive assets to the extent all existingand future indebtedness and obligations under the Series A Preferred Stock is paid in full. If any of these events were to occur, theremay 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 orSeries A Preferred Stock. As a result, the Class A common stock and Series A Preferred Stock effectively rank junior to all existing andfuture indebtedness and other liabilities of our subsidiaries, including our operating subsidiaries, and any capital stock of oursubsidiaries not held by us. Accordingly, our right to receive assets from any of our subsidiaries upon our bankruptcy, liquidation orreorganization, and the right of holders of shares of Class A common stock and Series A Preferred Stock to participate in those assets, isalso structurally subordinated to claims of that subsidiary’s creditors, including trade creditors. Even if we were a creditor of any of oursubsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of that subsidiary and any indebtednessof 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 beyondour 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 yieldof the securities (as a percentage of the then market price of the securities) relative to market interest rates. Increases in market interestrates, which have been at low levels relative to historical rates, may lead prospective purchasers of shares of Class A common stock orSeries A Preferred Stock to expect a higher distribution yield, and cause them to sell their Class A common stock or Series A PreferredStock. Accordingly, higher market interest rates could cause the market price of the Class A common stock and Series A PreferredStock to decrease.In addition, over the last several years, prices of equity securities in the U.S. trading markets have been experiencing extreme pricefluctuations. As a result of these and other factors, investors holding our Class A common stock and Series A Preferred Stock mayexperience a decrease in the value of their securities, which could be substantial and rapid, and could be unrelated to our financialcondition, 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 themarket 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. Theliquidity of any market for the Class A common stock and Series A Preferred Stock depends upon the number of stockholders, ourresults of operations and financial condition, the market for similar securities, the interest of securities dealers in making a market in theClass A common stock and Series A Preferred Stock, and other factors. To the extent that an active trading market is not maintained, theliquidity 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 ormandatory redemption, stockholders seeking liquidity will be limited to selling their respective shares of Series A Preferred Stock in thesecondary market. Active trading markets for the Series A Preferred Stock may not exist at such times, in which case the trading priceof 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 and Class B common stock vote together as a single class on all matters presented to our stockholders for their voteor 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 and Class B common stock as of December 31, 2018 through his direct and indirectownership in us.Affiliated owners are entitled to act separately with respect to their investment in us, and they have the ability to elect all of the membersof our board of directors, and thereby to control our management and affairs. In addition, affiliates are able to determine the outcome ofall matters requiring Class A common stock and Class B common stock shareholder approval, including mergers and other materialtransactions, and is able to cause or prevent a change in the composition of our board of directors or a change in control of ourcompany that could deprive our stockholders of an opportunity to receive a premium for their Class A common stock as part of a saleof our company. The existence of a significant shareholder, such as our Founder, may also have the effect of deterring hostiletakeovers, delaying or preventing changes in control or changes in management, or limiting the ability of our other stockholders toapprove 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 allmatters requiring shareholder approval, regardless of whether other stockholders believe that a potential transaction is in their own bestinterests. In any of these matters, the interests of affiliates may differ or30 Table of Contentsconflict with the interests of our other stockholders. Moreover, this concentration of stock ownership may also adversely affect thetrading price of our Class A common stock or Series A Preferred Stock to the extent investors perceive a disadvantage in owning stockof a company with a controlling shareholder.Holders of Series A Preferred Stock have extremely limited voting rights.Voting rights of holders of shares of Series A Preferred Stock are extremely limited. Our Class A common stock and our Class Bcommon stock are the only classes of our securities carrying full voting rights. Holders of the Series A Preferred Stock generally haveno voting rights.We are a “controlled company” under NASDAQ Global Select Market rules, and as such we are entitled to an exemption from certaincorporate governance standards of the NASDAQ Global Select Market, and you may not have the same protections afforded toshareholders 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 becausean affiliated holder controls more than 50% of our voting power. Under NASDAQ Global Select Market rules, a company of whichmore than 50% of the voting power is held by an individual, a group or another company is a “controlled company” and may elect notto 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 controlledcompany exemption. Our board of directors has determined not to have a nominating and corporate governance committee and that ourcompensation committee will not consist entirely of independent directors. As a result, non-independent directors may among otherthings, appoint future members of our board of directors, resolve corporate governance issues, establish salaries, incentives and otherforms 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 GlobalSelect 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 ofany 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 acquiredcompanies and books of customers from our affiliates and may do so in the future. We will continue to enter into back-to-backtransactions for purchases of commodities and derivatives on behalf of our affiliate. We will also continue to pay certain expenses onbehalf of several of our affiliates for which we will seek reimbursement. We will also continue to share our corporate headquarters withcertain affiliates. We cannot assure that our affiliates will reimburse us for the costs we have incurred on their behalf or perform theirobligations under any of these contracts.Our amended and restated certificate of incorporation and amended and restated bylaws, as well as Delaware law, contain provisionsthat could discourage acquisition bids or merger proposals, which may adversely affect the market price of our Class A commonstock.Our amended and restated certificate of incorporation authorizes our board of directors to issue preferred stock without shareholderapproval. On October 7, 2016, we filed a registration statement under the Securities Act on Form S-3 allowing us to offer and sell, fromtime to time, shares of preferred stock. The registration statement was declared effective on October 20, 2016. The election by ourboard 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 itmore difficult for a third party to acquire control of us, even if the change of control would be31 Table of Contentsbeneficial to our stockholders. Among other things, our amended and restated certificate of incorporation and amended and restatedbylaws:—provide for our board of directors to be divided into three classes of directors, with each class as nearly equal in number aspossible, serving staggered three year terms. Our staggered board may tend to discourage a third party from making a tenderoffer or otherwise attempting to obtain control of us, because it generally makes it more difficult for shareholders to replace amajority of the directors;—provide that the authorized number of directors may be changed only by resolution of the board of directors;—provide that all vacancies in our board, including newly created directorships, may, except as otherwise required by law or, ifapplicable, the rights of holders of a series of preferred stock, be filled by the affirmative vote of a majority of directors thenin 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 ourboard of directors to issue, without shareholder approval, preferred stock with voting or other rights or preferences that couldimpede the success of any attempt to change control of us. These and other provisions may have the effect of deferringhostile 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 fiftypercent of the outstanding Class A common stock and Class B common stock, any action required or permitted to be takenby the shareholders must be effected at a duly called annual or special meeting of shareholders and may not be effected byany consent in writing in lieu of a meeting of such shareholders, subject to the rights of the holders of any series of preferredstock with respect to such series (prior to such time, such actions may be taken without a meeting by written consent ofholders of the outstanding stock having not less than the minimum number of votes that would be necessary to authorize ortake 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 fiftypercent of the outstanding Class A common stock and Class B common stock, special meetings of our shareholders may onlybe called by the board of directors, the chief executive officer or the chairman of the board (prior to such time, specialmeetings may also be called by our Secretary at the request of holders of record of fifty percent of the outstanding Class Acommon stock and Class B common stock);—provide that our amended and restated certificate of incorporation and amended and restated bylaws may be amended by theaffirmative 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 electionas directors or new business to be brought before meetings of our shareholders. These procedures provide that notice ofshareholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is tobe taken. These requirements may preclude shareholders from bringing matters before the shareholders at an annual orspecial meeting.In addition, in our amended and restated certificate of incorporation, we have elected not to be subject to the provisions of Section 203of the Delaware General Corporation Law (the “DGCL”) regulating corporate takeovers until the date on which W. Keith Maxwell IIIno longer beneficially owns in the aggregate more than fifteen percent of the outstanding Class A common stock and Class B commonstock. 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 andexclusive forum for certain types of actions and proceedings that may be initiated by our32 Table of Contentsstockholders, 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 alternativeforum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusiveforum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary dutyowed by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim against us or anydirector or officer or other employee of ours arising pursuant to any provision of the DGCL, our amended and restated certificate ofincorporation or our bylaws, or (iv) any action asserting a claim against us or any director or officer or other employee of ours that isgoverned by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over theindispensable parties named as defendants therein. Any person or entity purchasing or otherwise acquiring any interest in shares of ourcapital stock will be deemed to have notice of, and consented to, the provisions of our amended and restated certificate of incorporationdescribed in the preceding sentence. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicialforum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuitsagainst us and such persons. Alternatively, if a court were to find these provisions of our amended and restated certificate ofincorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we mayincur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financialcondition 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 Acommon 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, fromtime to time, of Class A common stock, preferred stock, depositary shares and warrants. The registration statement also registers theClass A common stock held by our affiliates, Retailco and NuDevco (including Class A common stock that may be obtained uponconversion of Class B common stock). All of the shares of Class A common stock held by Retailco and NuDevco and registered on theregistration 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 theeffect, if any, that future issuances or sales of shares of our Class A common stock will have on the market price of our Class Acommon 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 maydiffer 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 uponliquidation, winding up or dissolution. The subsequent issuance of additional shares of Series A Preferred Stock, or the creation andsubsequent issuance of additional classes of preferred stock on parity with the Series A Preferred Stock, could dilute the interests of theholders of Series A Preferred Stock, and could affect our ability to pay distributions on, redeem or pay the liquidation preference on theSeries A Preferred Stock. Any issuance of preferred stock that is senior to the Series A Preferred Stock would not only dilute theinterests of the holders of Series A Preferred Stock, but also could affect our ability to pay distributions on, redeem or pay theliquidation preference on the Series A Preferred Stock.Furthermore, subject to compliance with the Securities Act or exemptions therefrom, employees who have received Class A commonstock 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.33 Table of ContentsWe are party to a Tax Receivable Agreement ("Tax Receivable Agreement" or "TRA") that generally provides for the payment by us toour 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 purchaseby us of units of our subsidiary from affiliates of our Founder, (ii) any tax basis increases resulting from the exchange of these units forshares of Class A common stock pursuant to the Exchange Right (or resulting from an exchange of units for cash pursuant to a CashOption) and (iii) any imputed interest deemed to be paid by us as a result of, and additional tax basis arising from, any payments wemake under the Tax Receivable Agreement. In addition, payments we make under the Tax Receivable Agreement will be increased byany 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 certaincircumstances 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, theobligation may nevertheless be significant and could adversely affect our liquidity and ability to pay dividends to the holders of ourClass 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 SparkHoldCo. For purposes of the Tax Receivable Agreement, cash savings in tax generally are calculated by comparing our actual taxliability 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 TaxReceivable 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 varydepending upon a number of factors, including the timing of the exchanges of Spark HoldCo units, the price of Class A common stockat the time of each exchange, the extent to which such exchanges are taxable, the amount and timing of the taxable income we generatein the future and the tax rate then applicable, and the portion of our payments under the Tax Receivable Agreement constitutingimputed interest or depletable, depreciable or amortizable basis. We expect that the payments that we will be required to make under theTax Receivable Agreement could be substantial.The payments under the Tax Receivable Agreement will not be conditioned upon a holder of rights under the Tax ReceivableAgreement having a continued ownership interest in either Spark HoldCo or us.During 2018, we made the payments required under the TRA for the 2015, 2016 and 2017 tax years. See Note 15 "Transactions withAffiliates" for a discussion of amounts paid and accrued under the TRA.In certain cases, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual benefits, ifany, 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 TaxReceivable Agreement, which calculation of anticipated future tax benefits will be based upon certain assumptions and deemed eventsset forth in the Tax Receivable Agreement, including the assumption that we have sufficient taxable income to fully utilize such benefitsand that any Spark HoldCo units that Retailco, LLC, NuDevco Retail, or their permitted transferees own on the termination date aredeemed to be exchanged on the termination date. Any early termination payment may be made significantly in advance of the actualrealization, 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 andcould have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms34 Table of Contentsof business combinations or other changes of control due to the additional transaction cost a potential acquirer may attribute tosatisfying such obligations. For example, if the Tax Receivable Agreement had been terminated as of December 31, 2018, the estimatedcontractual termination payment would be approximately $33.8 million (calculated using a discount rate equal to the London Inter-Bank Offered Rate ("LIBOR"), plus 200 basis points). The foregoing number is merely an estimate and the actual payment could differmaterially. 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 rightsunder the Tax Receivable Agreement will not reimburse us for any payments previously made under the Tax Receivable Agreement ifsuch basis increases or other benefits are subsequently disallowed, except that excess payments made to any such holder will be nettedagainst payments otherwise to be made, if any, to such holder after our determination of such excess. As a result, in suchcircumstances, we could make payments that are greater than our actual cash tax savings, if any, and may not be able to recoup thosepayments, 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 votingpower 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 ofpreferred stock having such designations, preferences, limitations and relative rights, including preferences over our Class A commonstock with respect to dividends and distributions, as our board of directors may determine. Through December 31, 2018, we haveissued an aggregate of 3,707,256 shares of Series A Preferred Stock.The terms of the preferred stock we offer or sell could adversely impact the voting power or value of our Class A common stock. Forexample, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening ofspecified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences wemight assign to holders of preferred stock, such as the Series A Preferred Stock, could affect the residual value of the Class A commonstock.For as long as we are an emerging growth company, we will not be required to comply with certain reporting requirements, includingthose 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 growthcompany” under the JOBS Act. For as long as we are an emerging growth company, which may be up to five full fiscal years, unlikeother public companies, we will not be required to, among other things, (i) provide an auditor’s attestation report on management’sassessment 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 requirements adopted by the PCAOB requiring mandatory audit firm rotation or a supplement tothe auditor’s report in which the auditor would be required to provide additional information about the audit and the financialstatements 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 lastday of our 2019 fiscal year. After we cease to be an "emerging growth company," we may incur significant additional expense anddevote 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 differentthan what you may receive from other public companies in which you hold an equity interest. To the extent that we rely on any of theexemptions available to emerging growth companies, you will receive less information about our executive compensation and internalcontrol over financial reporting than issuers that are not emerging growth companies. If some investors find our securities to be lessattractive as a result, there may be a less active trading market for our securities and the price may be more volatile.35 Table of ContentsOur amended and restated certificate of incorporation limits the fiduciary duties of one of our directors and certain of our affiliatesand restricts the remedies available to our stockholders for actions taken by our Founder or certain of our affiliates that mightotherwise constitute breaches of fiduciary duty.Our amended and restated certificate of incorporation contains provisions that we renounce any interest in existing and futureinvestments 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 orofficer who is presented an opportunity solely in his capacity as a director or officer). Because of this provision, these persons andentities have no obligation to offer us those investments or opportunities that are offered to them in any capacity other than solely as anofficer or director. If one of these persons or entities pursues a business opportunity instead of presenting the opportunity to us, we willnot 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 APreferred Stock on the date the Series A Preferred Stock becomes redeemable by us or on any particular date afterwards.The Series A Preferred Stock represents a perpetual equity interest in us, and the securities have no maturity or mandatory redemptiondate and are not redeemable at the option of investors under any circumstances. As a result, unlike our indebtedness, the Series APreferred 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 APreferred Stock may be required to bear the financial risks of an investment in the Series A Preferred Stock for an indefinite period oftime. In addition, the Series A Preferred Stock will rank junior to all our current and future indebtedness (including indebtednessoutstanding under the Senior Credit Facility) and other liabilities. The Series A Preferred Stock will also rank junior to any otherpreferred stock ranking senior to the Series A Preferred Stock we may issue in the future with respect to assets available to satisfy claimsagainst 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 ispossible, however, that one or more rating agencies might independently determine to assign a rating to the Series A Preferred Stock orthat 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 forwhich 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 othersecurities with a rating, such ratings, if they are lower than market expectations or are subsequently lowered or withdrawn, couldadversely affect the market for or the market value of the Series A Preferred Stock. Ratings only reflect the views of the issuing ratingagency or agencies and such ratings could at any time be revised downward or withdrawn entirely at the discretion of the issuing ratingagency. 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 PreferredStock 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 acquiringus.The Change of Control Conversion Right of the Series A Preferred Stock provided in the Certificate of Designation may have the effectof discouraging a third party from making an acquisition proposal for us or of delaying, deferring or preventing certain of our changeof control transactions under circumstances that otherwise could provide the holders of our Series A Preferred Stock with theopportunity to realize a premium over the then-current market price of such equity securities or that stockholders may otherwise believeis 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 LIBORRate could negatively impact our ability to pay dividends on the Series A Preferred Stock and Class A common stock.36 Table of ContentsIf we do not repurchase or redeem our Series A Preferred Stock on or after April 15, 2022, a substantial increase in the Three-MonthLIBOR Rate could negatively impact our ability to pay dividends on the Series A Preferred Stock. An increase in the dividends payableon our Series A Preferred Stock would negatively impact dividends on our Class A common stock. We cannot assure you that we willhave adequate sources of capital to repurchase or redeem the Series A Preferred Stock on or after April 15, 2022. If we are unable torepurchase or redeem the Series A Preferred Stock and our ability to pay dividends on the Series A Preferred Stock and Class Acommon stock is negatively impacted, the market value of the Series A Preferred Stock and Class A common stock could be materiallyadversely impacted.We may not have sufficient earnings and profits in order for dividends on the Series A Preferred Stock to be treated as dividends forU.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, ascalculated for U.S. federal income tax purposes. If this occurs, it will result in the amount of the dividends that exceed such earningsand profits being treated for U.S. federal income tax purposes first as a return of capital to the extent of the beneficial owner’s adjustedtax basis in the Series A Preferred Stock, and the excess, if any, over such adjusted tax basis as capital gain. Such treatment willgenerally 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 eventhough 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 certaincircumstances. A failure to adjust (or to adjust adequately) the Conversion Rate after an event that increases your proportionate interestin 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 againstsubsequent payments on the Series A Preferred Stock. In April 2016, the Internal Revenue Service issued new proposed income taxregulations in regard to the taxability of changes in conversion rights that will apply to the Series A Preferred Stock when published infinal form and may be applied to us before final publication in certain instances.Item 1B.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITIONAND RESULTS OF OPERATIONSThe following discussion and analysis of our financial condition and results of operations should be read in conjunction with theconsolidated financial statements and the related notes thereto included elsewhere in this Annual Report. In this Annual Report, theterms “Spark Energy,” “Company,” “we,” “us” and “our” refer collectively to Spark Energy, Inc. and its subsidiaries.OverviewWe are an independent retail energy services company founded in 1999 that provides residential and commercial customers incompetitive markets across the United States with an alternative choice for their natural gas and electricity. We purchase our natural gasand electricity supply from a variety of wholesale providers and bill our customers monthly for the delivery of natural gas andelectricity based on their consumption at either a fixed or variable price. Natural gas and electricity are then distributed to our customersby local regulated utility companies through their existing infrastructure. As of December 31, 2018, we operated in 94 utility serviceterritories 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 withmarket counterparts and ISOs and supply electricity to residential and commercial consumers pursuant to fixed-price andvariable-price contracts. For the years ended December 31, 2018, 2017 and 2016, approximately 86%, 82% and 76%,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 withmarket counterparties and supply natural gas to residential and commercial consumers pursuant to fixed-price and variable-pricecontracts. For the years ended December 31, 2018, 2017 and 2016, approximately 14%, 18% and 24%, respectively, of ourretail revenues were derived from the sale of natural gas. We also attempt to improve our profitability on natural gas byidentifying and executing on wholesale natural gas arbitrage opportunities, which we refer to as asset optimization.Recent DevelopmentsIncrease in Commitments Under Our Senior Credit FacilityOn January 28, 2019, the Company and Co-Borrowers exercised the accordion feature in the Senior Credit Facility, bringing totalcommitments under the Senior Credit Facility to $217.5 million.Residential Customer EquivalentsWe measure our number of customers using residential customer equivalents ("RCEs"). The following table shows our RCEs bysegment as of December 31, 2018, 2017 and 2016:RCEs: December 31,(In thousands)201820172016Retail Electricity754868571Retail Natural Gas154174203Total Retail9081,04277441 Table of ContentsThe following table details our count of RCEs by geographical region as of December 31, 2018:RCEs by Geographic Region: (In thousands)Electricity % of TotalNatural Gas % of TotalTotal % of TotalNew England34546%2919%37441%Mid-Atlantic27236%5636%32836%Midwest659%4932%11413%Southwest729%2013%9210%Total754100%154100%908100%The geographical regions noted above include the following states:•New England - Connecticut, Maine, Massachusetts and New Hampshire;•Mid-Atlantic - Delaware, Maryland (including the District of Columbia), New Jersey, New York and Pennsylvania;•Midwest - Illinois, Indiana, Michigan and Ohio; and•Southwest - Arizona, California, Colorado, Florida, Nevada and Texas.Across our market areas, we have operated under a number of different retail brands. During 2018, we began consolidating brands andbilling systems. In 2019, we expect to further consolidate our brands and systems as we simplify our business.Drivers of Our BusinessThe success of our business and our profitability are impacted by a number of drivers, the most significant of which are discussedbelow.Customer GrowthCustomer growth is a key driver of our operations. Our customer growth strategy includes growing organically through traditional saleschannels complemented by customer portfolio and business acquisitions. During 2018, we added a total of approximately 432,000RCEs, of which 29,000 RCEs were added as part of the acquisitions of HIKO Energy, LLC ("HIKO"), 52,000 RCEs were added as aresult of customer portfolio acquisitions from Starion Energy Inc. ("Starion") and from an affiliated company, and the remaining wereadded were through our organic sales channels.Organic SalesOur organic sales strategies are designed to offer competitive pricing, price certainty, and/or green product offerings to residential andcommercial customers. We manage growth on a market-by-market basis by developing price curves in each of the markets we serveand comparing the market prices to the price offered by the local regulated utility. We then determine if there is an opportunity in aparticular market based on our ability to create a competitive product on economic terms that provides customer value and satisfies ourprofitability objectives. We develop marketing campaigns using a combination of sales channels. Our marketing team continuouslyevaluates the effectiveness of each customer acquisition channel and makes adjustments in order to achieve desired targets.AcquisitionsWe acquire companies and portfolios of customers through both external and affiliated channels. In 2016, we acquired approximately341,000 RCEs through our acquisitions of Provider Power, LLC ("Provider Power") and Major Energy Companies ("Major Energy"). In2017, we acquired approximately 206,000 RCEs through42 Table of Contentsacquisitions of Verde Energy USA Holdings, LLC ("Verde Energy"), Perigee Energy, LLC ("Perigee Energy"), and a customerportfolio. In 2018, we have added approximately 81,000 RCEs through our acquisitions of HIKO, a customer portfolio from anaffiliate, and a customer portfolio from Starion.Our ability to realize returns from acquisitions that are acceptable to us is dependent on our ability to successfully identify, negotiate forfinance and integrate acquisitions.RCE ActivityThe following table shows our RCE activity during the years ended December 31, 2018, 2017 and 2016.(In thousands)Retail ElectricityRetail Natural GasTotal% Net AnnualIncrease (Decrease)December 31, 2015257158415 Additions550131681 Attrition(236)(86)(322) December 31, 201657120377487% Additions65961720 Attrition(362)(90)(452) December 31, 20178681741,04235% Additions36369432 Attrition(477)(89)(566) December 31, 2018754154908(13)%The increase of our RCE counts in 2016 and 2017 related to the acquisition of customers and businesses in excess of natural customerattrition during those years. In 2018, our attrition exceeded customer adds due to lower organic sales spending, fewer acquisitions andslightly higher attrition impacted by our brand consolidation activities and our intentional non-renewable of certain larger C&I customercontracts. Average monthly attrition rates during 2016, 2017, and 2018 were as follows: Year EndedQuarter Ended December 31December 31September 30June 30March 3120164.3%4.8%3.8%4.1%4.4%20174.3%4.9%4.2%4.1%3.8%20184.7%6.7%4.0%3.7%4.2%Customer attrition occurs primarily as a result of: (i) customer initiated switches; (ii) residential moves and (iii) disconnection forcustomer payment defaults. Customer attrition during the year ended December 31, 2018 was slightly higher than the prior year due tobrand consolidations and our intentional non-renewal of certain large C&I contracts.Customer Acquisition CostsManaging customer acquisition costs is a key component of our profitability. Customer acquisition costs are those costs related toobtaining customers organically and do not include the cost of acquiring customers through acquisitions, which are recorded ascustomer relationships. For each of the three years ended December 31, 2018, customer acquisition costs were as follows:43 Table of Contents (In thousands)201820172016Customer Acquisition Costs$13,673$25,874$24,934We attempt to maintain a disciplined approach to recovery of our customer acquisition costs within a 12 month period. We capitalizeand amortize our customer acquisition costs over a two year period, which is based on our estimate of the expected average length of acustomer relationship. We factor in the recovery of customer acquisition costs in determining which markets we enter and the pricing ofour products in those markets. Accordingly, our results are significantly influenced by our customer acquisition costs. Changes incustomer acquisition costs from period to period reflect our focus on growing organically versus growth through acquisitions. We arecurrently focused on growing through organic sales channels although we continue to evaluate opportunities to acquire customersthrough acquisitions where they make sense economically or strategically.Customer Credit RiskApproximately 66% of our revenues are derived from customers in utilities where customer credit risk is borne by the utility inexchange for a discount on amounts billed. Where we have customer credit risk, we record bad debt based on an estimate ofuncollectible amounts. Our bad debt expense on non-POR revenues was as follows: Year Ended December 31 201820172016Total Non-POR Bad Debt as Percent of Revenue2.6%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 brandconsolidations. During the year ended December 31, 2017, we experienced higher bad debt expense versus 2016 due to HurricaneHarvey, coupled with the fact that the year ended December 31, 2016 included a reversal of a portion of our bad debt reserve as a resultof improved collection efforts.To manage our current exposure, we have increased our focus on collection efforts and timely billing along with tighter creditrequirements for new enrollments in non-POR marketsFor the years ended December 31, 2018, 2017 and 2016, approximately 66%, 66% and 67%, respectively, of our retail revenues werecollected through POR programs where substantially all of our credit risk was with local regulated utility companies. As ofDecember 31, 2018, 2017 and 2016, all of these local regulated utility companies had investment grade ratings. During these sameperiods, we paid these local regulated utilities a weighted average discount of approximately 1.0%, 1.1% and 1.3%, respectively, oftotal revenues for customer credit risk protection.Weather ConditionsWeather conditions directly influence the demand for natural gas and electricity and affect the prices of energy commodities. Ourhedging strategy is based on forecasted customer energy usage, which can vary substantially as a result of weather patterns deviatingfrom historical norms. We are particularly sensitive to this variability in our residential customer segment in which energy usage ishighly sensitive to weather conditions that impact heating and cooling demand.Our risk management policies direct that we hedge substantially all of our forecasted demand, which is typically hedged to long-termnormal weather patterns. We also attempt to add additional contracts from time to time to protect us from volatility in markets where wehave historically experienced higher exposure to extreme weather conditions. Because we attempt to match commodity purchases toanticipated demand, unanticipated changes in weather patterns can have a significant impact on our operating results and cash flowsfrom period to period.Asset Optimization44 Table of ContentsOur asset optimization opportunities primarily arise during the winter heating season when demand for natural gas is typically at itshighest. Given the opportunistic nature of these activities and because we account for these activities using the mark to market methodof accounting, we experience variability in our earnings from our asset optimization activities from year to year.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 endedDecember 31, 2018, 2017 and 2016, respectively.45 Table of ContentsNon-GAAP Performance MeasuresWe use the Non-GAAP performance measures of Adjusted EBITDA and Retail Gross Margin to evaluate and measure our operatingresults. These measures for the three years ended December 31, 2018 were as follows: Year Ended December 31,(in thousands)2018 2017 2016Adjusted EBITDA$70,716 $102,884 $81,892Retail Gross Margin$185,109 $224,509 $182,369Adjusted EBITDA. We define “Adjusted EBITDA” as EBITDA less (i) customer acquisition costs incurred in the current period, plus orminus (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) beforethe 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 AdjustedEBITDA calculation because such costs reflect a cash outlay in the period in which they are incurred, even though we capitalize andamortize such costs over two years. We do not deduct the cost of customer acquisitions through acquisitions of businesses or portfoliosof customers in calculating Adjusted EBITDA.We deduct our net gains (losses) on derivative instruments, excluding current period cash settlements, from the Adjusted EBITDAcalculation in order to remove the non-cash impact of net gains and losses on these instruments. We also deduct non-cashcompensation expense that results from the issuance of restricted stock units under our long-term incentive plan due to the non-cashnature of the expense. Finally, we also adjust from time to time other non-cash or unusual and/or infrequent charges due to either theirnon-cash nature or their infrequency.We believe that the presentation of Adjusted EBITDA provides information useful to investors in assessing our liquidity and financialcondition and results of operations and that Adjusted EBITDA is also useful to investors as a financial indicator of our ability to incurand service debt, pay dividends and fund capital expenditures. Adjusted EBITDA is a supplemental financial measure that managementand 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 tofinancing 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.The GAAP measures most directly comparable to Adjusted EBITDA are net income and net cash provided by operating activities. Thefollowing table presents reconciliations of Adjusted EBITDA to these GAAP measures for each of the periods indicated.46 Table of Contents Year Ended December 31,(in thousands)2018 2017 2016Reconciliation of Adjusted EBITDA to Net Income: Net (loss) income$(14,392) $75,044 $65,673Depreciation and amortization52,658 42,341 32,788Interest expense9,410 11,134 8,859Income tax expense2,077 38,765 10,426EBITDA49,753 167,284 117,746Less: Net, (Losses) gains on derivative instruments(18,170) 5,008 22,407Net, Cash settlements on derivative instruments(10,587) 16,309 (2,146)Customer acquisition costs13,673 25,874 24,934 Plus: Non-cash compensation expense5,879 5,058 5,242 Contract termination charge related to Major EnergyCompanies change of control— — 4,099 Change in Tax Receivable Agreement liability (1)— (22,267) —Adjusted EBITDA $70,716 $102,884 $81,892(1) Represents the change in the value of the Tax Receivable Agreement liability due to U.S. Tax Reform.

See discussion in Note 13 "Income Taxes."Retail Gross Margin. We define retail gross margin as operating income (loss) 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 derivativeinstruments, and (v) net current period cash settlements on non-47 Table of Contentstrading derivative instruments. Retail gross margin is included as a supplemental disclosure because it is a primary performancemeasure used by our management to determine the performance of our retail natural gas and electricity segments. As an indicator of ourretail 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 operatingperformance.The GAAP measure most directly comparable to Retail Gross Margin is operating income. The following table presents a reconciliationof Retail Gross Margin to operating income for each of the periods indicated.

Adjusted EBITDA and Retail Gross Margin are notpresentations made in accordance with GAAP and have limitations as analytical tools. You should not consider Adjusted EBITDA orRetail Gross Margin in isolation or as a substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA andRetail Gross Margin exclude some, but not all, items that affect net (loss) income, net cash provided by operating activities, andoperating (loss) income, and are defined differently by different companies in our industry, our definition of Adjusted EBITDA andRetail 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 thecomparable GAAP measures, understanding the differences between the measures and incorporating these data points intomanagement’s decision-making process.48 Table of ContentsConsolidated Results of Operations(In Thousands)Year Ended December 31,2018 2017 2016Revenues: Retail revenues$1,001,417 $798,772 $547,283Net asset optimization revenues (expenses)4,511 (717) (586)Total Revenues1,005,928 798,055 546,697Operating Expenses: Retail cost of revenues845,493 552,167 344,944General and administrative expense111,431 101,127 84,964Depreciation and amortization52,658 42,341 32,788Total Operating Expenses1,009,582 695,635 462,696Operating (loss) income(3,654) 102,420 84,001Other (expense)/income: Interest expense(9,410) (11,134) (8,859)Change in Tax Receivable Agreement liability (1)—22,267 —Interest and other income749 256 957Total other (expenses)/income(8,661) 11,389 (7,902)(Loss) income before income tax expense(12,315) 113,809 76,099Income tax expense2,077 38,765 10,426Net (loss) income$(14,392) $75,044 $65,673Other Performance Metrics: Adjusted EBITDA (2)$70,716 $102,884 $81,892 Retail Gross Margin (2)185,109 224,509 182,369 Customer Acquisition Costs13,673 25,874 24,934 RCE Attrition4.7% 4.3% 4.3% Distributions paid to Class B non-controlling unit holders and dividends paid to Class Acommon shareholders$(45,261) $(43,319) $(43,297)(1) Represents the change in the value of the Tax Receivable Agreement liability due to U.S. Tax Reform.

See “—Non-GAAP Performance Measures” for a reconciliation of Adjusted EBITDA andRetail Gross Margin to their most directly comparable financial measures presented in accordance with GAAP.Total Revenues. Total revenues for the year ended December 31, 2018 were approximately $1,005.9 million, an increase ofapproximately $207.8 million, or 26%, from approximately $798.1 million for the year ended December 31, 2017. This increase wasprimarily due to an increase in electricity volumes driven by the acquisitions of the HIKO and two customer portfolios, full year resultsfrom the Verde Companies, and higher-than-normal electricity and natural gas pricing in 2018, partially offset by a decrease in naturalgas volumes due to warmer-than-normal weather in the second and third quarters of 2018. Total revenues for the year endedDecember 31, 2017 increased approximately $251.4 million, or 46%, from approximately $546.7 million for the year endedDecember 31, 2016. This increase was primarily due to an increase in electricity and natural gas volumes driven by full year results ofthe Major Energy Companies and the Provider Companies which were both acquired in 2016, and by the acquisition of the VerdeCompanies during 2017, partially offset by decreased electricity pricing.49 Table of ContentsAnalysis of the impact of changes in prices and volumes between the years ended December 31, 2018, 2017 and 2016 are as follows: 2018 vs. 20172017 vs. 2016Change in electricity volumes sold$182.5$258.6Change in natural gas volumes sold(11.1)10.7Change in electricity unit revenue per MWh23.4(18.2)Change in natural gas unit revenue per MMBtu7.90.4Change in net asset optimization revenue (expense)5.1(0.1)Change in total revenues$207.8$251.4Retail Cost of Revenues. Total retail cost of revenues for the year ended December 31, 2018 was approximately $845.5 million, anincrease of approximately $293.3 million, or 53%, from approximately $552.2 million for the year ended December 31, 2017. Thisincrease was primarily due to an increase in electricity volumes driven by the acquisitions of HIKO and two customer portfolios, fullyear results from the Verde Companies, higher-than-normal electricity and natural gas prices due to the extreme unpredictable weatherin the first quarter of 2018, increased capacity costs in the second and third quarter of 2018, and additional hedges in ERCOT in thethird quarter of 2018. Total retail cost of revenues for the year ended December 31, 2017 increased approximately $207.3 million, or60%, from approximately $344.9 million for the year ended December 31, 2016. This increase was primarily due to additional volumesdriven by full year results of the Major Energy Companies and the Provider Companies, and the acquisition of the Verde Companies,which resulted in higher electricity and natural gas supply costs, offset by a decrease in the value of our retail derivative portfolio.Analysis of the impact of changes in prices and volumes between the years ended December 31, 2018, 2017, and 2016 are as follows: 2018 vs. 20172017 vs. 2016Change in electricity volumes sold$138.5$185.4Change in natural gas volumes sold(5.9)5.4Change in electricity unit cost per MWh101.214.6Change in natural gas unit cost per MMBtu8.24.0Change in value of retail derivative portfolio51.3(2.1)Change in retail cost of revenues$293.3$207.3General and Administrative Expense. General and administrative expense for the year ended December 31, 2018 was approximately$111.4 million, an increase of approximately $10.3 million, or 10%, as compared to $101.1 million for the year ended December 31,2017. This increase was primarily attributable to reductions in the fair value of earnout liabilities, which decreased general andadministrative expenses in 2017 to a greater extent than in 2018, increased commissions paid to commercial brokers, and variable costsassociated with increased RCEs from our acquisitions. General and administrative expense for the year ended December 31, 2017increased approximately $16.1 million or 19%, as compared to $85.0 million for the year ended December 31, 2016. This increase wasprimarily due to increased billing and other variable costs associated with increased RCEs, including those added as a result of full yearresults of the Major Energy Companies and the Provider Companies and the acquisition of the Verde Companies, as well as costsrelated to the acquisition of customers by the Verde Companies that we do not capitalize, partially offset by a net decrease in fair valueof earnout liabilities, which decreased general and administrative expenses.Depreciation and Amortization Expense. Depreciation and amortization expense for the year ended December 31, 2018 wasapproximately $52.7 million, an increase of approximately $10.4 million, or 24%, from approximately $42.3 million for the year endedDecember 31, 2017. This increase was primarily due to the increased amortization expense associated with customer relationshipintangibles from the acquisitions of the Verde Companies, HIKO and customers from an affiliate, and the write-off of assets no longerin use as a result of integration activities.50 Table of ContentsDepreciation and amortization expense for the year ended December 31, 2017 increased approximately $9.5 million, or 29%, fromapproximately $32.8 million for the year ended December 31, 2016. This increase was primarily due to the increased amortizationexpense associated with customer intangibles from full year results of the Major Energy Companies and the Provider Companies andthe acquisition of the Verde Companies.Customer Acquisition Cost. Customer acquisition cost for the year ended December 31, 2018 was approximately $13.7 million, adecrease of approximately $12.2 million, or 47% from approximately $25.9 million for the year ended December 31, 2017. Thisdecrease was primarily due to a decrease in the number of organic sales in 2018 as we were more focused on acquisitions ofbusinesses, customer portfolio additions, and integration. Customer acquisition cost for the year ended December 31, 2017 increasedapproximately $1.0 million, or 4% from approximately $24.9 million for the year ended December 31, 2016. This increase wasprimarily due to customer acquisition costs of the Major Energy Companies, the Provider Companies and Verde Companies offset bydecreased organic sales in the second half of the year as we devoted resources to the acquisition and integration of the VerdeCompanies. 51 Table of ContentsOperating Segment Results Year Ended December 31, 201820172016 (in thousands, except volume and per unit operating data)Retail Electricity SegmentTotal Revenues$863,451$657,566$417,229Retail Cost of Revenues762,771477,012286,795Less: Net (Losses) Gains on non-trading derivatives, net of cashsettlements(23,988)22,08612,298Retail Gross Margin (1) —Electricity$124,668$158,468$118,136Volumes—Electricity (MWhs)8,630,6536,755,6634,170,593Retail Gross Margin (2) —Electricity per MWh$14.44$23.46$28.33Retail Natural Gas SegmentTotal Revenues$137,966$141,206$130,054Retail Cost of Revenues82,72275,15558,149Less: Net (Losses) Gains on non-trading derivatives, net of cashsettlements(5,197)107,672Retail Gross Margin (1) —Gas$60,441$66,041$64,233Volumes—Gas (MMBtus)16,778,39318,203,68416,819,713Retail Gross Margin (2) —Gas per MMBtu$3.60$3.63$3.82(1) Reflects the Retail Gross Margin attributable to our Retail Natural Gas Segment or Retail Electricity Segment, as applicable.

Total revenues for the Retail Electricity Segment for theyear ended December 31, 2017 increased approximately $240.4 million, or 58%, from approximately $417.2 million for the year endedDecember 31, 2016. This increase was primarily due to an increase in volume from the acquisitions of the Major Energy Companies,the Provider Companies and the Verde Companies and the addition of several higher volume commercial customers in the East, whichresulted in an increase in revenues of $258.6 million. This increase was partially offset by a decrease in electricity pricing, driven by thelower electricity pricing environment from milder than anticipated weather, which resulted in a decrease of $18.2 million.Retail cost of revenues for the Retail Electricity Segment for the year ended December 31, 2018 was approximately $762.8 million, anincrease of approximately $285.8 million, or 60%, from approximately $477.0 million for the year ended December 31, 2017.

This increase was primarily due to our full year results of the Major Energy Companiesand an increased number of higher volume C&I customers.Liquidity and Capital ResourcesOverviewOur primary sources of liquidity are cash generated from operations and borrowings under our Senior Credit Facility. Our principalliquidity 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, collateralposting requirements on our derivative instruments portfolio, distributions, the effects of the timing between the settlement of payablesand receivables, including the effect of bad debts, weather conditions, and our general working capital needs for ongoing operations.We believe that cash generated from operations and our available liquidity sources will be sufficient to sustain current operations and topay required taxes and quarterly cash distributions, including the quarterly dividends to the holders of the Class A common stock andthe Series A Preferred Stock, for the next twelve months. We believe that the financing of any additional growth through acquisitions orthe 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 gasand electricity, and market volatility and our then existing capital structure and requirements.Liquidity PositionThe following table details our available liquidity as of December 31, 2018:December 31,($ in thousands)2018Cash and cash equivalents$41,002Senior Credit Facility Availability (1)4,360Subordinated Debt Availability (2)15,000Total Liquidity$60,362(1) Reflects amount of Letters of Credit that could be issued based on existing covenants as of December 31, 2018.(2) The availability of the Subordinated Facility is dependent on our Founder's willingness and ability to lend. See "Subordinated Debt Facility."54 Table of ContentsBorrowings and related postings of letters of credit under our Senior Credit Facility are subject to material variations on a seasonal basisdue to the timing of commodity purchases to satisfy natural gas inventory requirements and to meet customer demands during periodsof peak usage. Additionally, borrowings are subject to borrowing base and covenant restrictions.On January 28, 2019, the Company and Co-Borrowers exercised the accordion feature in the Senior Credit Facility, bringing totalcommitments under the Senior Credit Facility to $217.5 million.Sources of Liquidity and Capital ResourcesSenior Credit FacilityAs of December 31, 2018, we had total commitments of $192.5 million, of which $178.9 million was outstanding, including $49.4million of outstanding letters of credit. In January 2019, our total commitments under our Senior Credit Facility increased to $217.5million. Under the Senior Credit Facility, we have various limits on advances for Working Capital Loans, Letters of Credit and BridgeLoans. The Senior Credit Facility matures on May 19, 2020. For a description of the terms and conditions of our Senior Credit Facility,including descriptions of the interest rate, commitment fee, covenants and terms of default, please see Note 10 "Debt" in the notes toour consolidated financial statements. As of December 31, 2018, we were in compliance with the covenants under our Senior CreditFacility.Subordinated Debt FacilityOur Subordinated Facility allows us to draw advances in increments of no less than $1.0 million per advance up to $25.0 million.Although we may use the Subordinated Facility from time to time to enhance short term liquidity, we do not view the SubordinatedFacility as a material source of liquidity. See Note 10 "Debt" for additional details. As of December 31, 2018, there was $10.0 millionoutstanding borrowings under the Subordinated Facility, which was repaid in January 2019.Uses of Liquidity and Capital ResourcesRepayment of Current Portion of Senior Credit FacilityOur Senior Credit Facility matures in 2020, and thus, no amounts are due currently. However, due to the revolving nature of the facility,excess cash available is generally used to reduce the balance outstanding, which at December 31, 2018 was $129.5 million. The currentvariable interest rate on the facility at December 31, 2018 was 5.48%.Customer AcquisitionsOur customer acquisition strategy consists of customer growth obtained through organic customer additions as well as opportunisticacquisitions. During the years ended December 31, 2018 and 2017, we spent a total of $13.7 million and $25.9 million, respectively,on organic customer acquisitions. Our ability to grow our customer base organically or by acquisition is important to our success as weexperience ongoing customer attrition each period.Capital ExpendituresOur capital requirements each year are relatively low and generally consist of minor purchases of equipment or information systemupgrades and improvements. Capital expenditures for the year ended December 31, 2018 included approximately $1.4 million relatedto information systems improvements.Dividends and Distributions55 Table of ContentsFor the year ended December 31, 2018, we paid dividends to holders of our Class A common stock of $0.725 per share or $9.8 millionin the aggregate. In order to pay our stated dividends to holders of our Class A common stock, our subsidiary, Spark HoldCo isrequired to make corresponding distributions to holders of Class B common stock (our non-controlling interest holders). As a result,during the year ended December 31, 2018, Spark HoldCo made distributions of $15.5 million to our non-controlling interest holdersrelated to the dividend payments to our Class A shareholders.For the year ended December 31, 2018, we paid $7.0 million of dividends to holders of our Series A Preferred Stock, and as ofDecember 31, 2018, we had accrued $2.0 million related to dividends to holders of our Series A Preferred Stock, which we paid onJanuary 15, 2019. For the year ended December 31, 2018, we declared dividends of $2.1875 per share or $8.1 million in the aggregateon our Series A Preferred Stock.On January 17, 2019, our Board of Directors declared a quarterly cash dividend in the amount of $0.18125 per share to holders of ourClass A common stock and $0.546875 per share for the Series A Preferred Stock. Dividends on Class A common stock will be paid onMarch 15, 2019 to holders of record on March 1, 2019 and Series A Preferred Stock dividends will be paid on April 15, 2019 to holdersof record on April 1, 2019.Our ability to pay dividends in the future will depend on many factors, including the performance of our business and restrictions underour Senior Credit Facility. If our business does not generate sufficient cash for Spark HoldCo to make distributions to us to fund ourClass A common stock and Series A Preferred Stock dividends, we may have to borrow to pay such amounts. Further, even if ourbusiness generates cash in excess of our current annual dividend (of $0.725 per share on our Class A common stock), we may reinvestsuch excess cash flows in our business and not increase the dividends payable to holders of our Class A common stock. Our futuredividend policy is within the discretion of our Board of Directors and will depend upon the results of our operations, our financialcondition, capital requirements and investment opportunities.Tax Receivable AgreementWe are required to make payments under a Tax Receivable Agreement that we have entered into with companies affiliated with ourFounder and majority shareholder. This agreement generally provides for the payment by the Company 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 have realized incertain circumstances) in future periods. The Company retains the benefit of the remaining 15% of these tax savings. Except in caseswhere we elect to terminate the Tax Receivable Agreement early (or the Tax Receivable Agreement is terminated early due to certaindefined changes of control) or we have available cash but fail to make payments when due, we may request to defer payments dueunder the Tax Receivable Agreement for up to five years if we do not have available cash to satisfy our payment obligations, or if ourcontractual obligations limit our ability to make these payments. Any such deferred payments accrue interest. If we were to defersubstantial payment obligations on an ongoing basis, the accrual of those obligations would reduce the availability of cash for otherpurposes, but we would not be prohibited from paying dividends on our Class A common stock. For the year ended December 31,2018, we paid a total of $6.2 million related to TRA payments for the 2015, 2016, and 2017 tax years. As of December 31, 2018, wehave a total liability related to the TRA on our balance sheet of $27.6 million. See Note 15 "Transactions with Affiliates" in the notes toour consolidated financial statements for additional details on the Tax Receivable Agreement.Verde Promissory NoteIn January 2018, we issued an amended and restated promissory note to the sellers of the Verde Companies (the "Verde PromissoryNote"). As of December 31, 2018, there was $1.0 million outstanding under the Verde Promissory Note, all of which was paid inJanuary 2019. The note bore interest at 9% per annum, and we made monthly payments of principal and associated interest, a portionof which was deposited into an escrow account to56 Table of Contentsprovide security for certain indemnification claims and obligations under the Verde purchase agreement. As of December 31, 2018, atotal of $7.6 million was held in escrow for such claims.Verde Earnout Termination NoteIn January 2018, we issued a promissory note in the principal amount of $5.9 million in connection with an agreement to terminate theearnout obligation arising in connection with our acquisition of the Verde Companies. The note matures in June 2019 (subject to earlymaturity upon certain events) and bears interest at a rate of 9% per annum. We are permitted to withhold amounts otherwise due atmaturity related to certain indemnifiable matters. Interest is payable monthly on the first day of each month in which the note isoutstanding.Cash FlowsOur cash flows were as follows for the respective periods (in thousands): Year Ended December 31, 2018 2017 2016Net cash provided by operating activities$59,763 $62,131 $66,950Net cash used in investing activities$(18,981) $(77,558) $(33,489)Net cash (used in) provided by financing activities$(20,563) $25,886 $(18,975)Cash Flows Provided by Operating Activities. Cash flows provided by operating activities for the year ended December 31, 2018decreased by $2.4 million compared to the year ended December 31, 2017. The decrease was primarily the result of a decrease in thechanges in working capital for the year ended December 31, 2018 and the impact of extreme weather events during the first quarter of2018. Cash flows provided by operating activities for the year ended December 31, 2017 decreased by $4.8 million compared to theyear ended December 31, 2016. The decrease was primarily the result of a decrease in the changes in working capital, offset by anincrease in retail gross margin for the year ended December 31, 2017 following several significant acquisitions in 2016 and 2017.Cash Flows Used in Investing Activities. Cash flows used in investing activities decreased by $58.6 million for the year endedDecember 31, 2018. The decrease was primarily the result of the $81.3 million acquisition of the Verde Companies, Perigee and othercustomers during the year ended December 31, 2017, offset by the acquisition of HIKO of $14.3 million during the year endedDecember 31, 2018. Cash flows used in investing activities increased by $44.1 million for the year ended December 31, 2017, whichwas primarily due to the funding of the acquisition of the Verde Companies and the acquisitions of Perigee and other customers duringthe year ended December 31, 2017, as well as earnout payments made during the year ended December 31, 2017 related to theProvider Companies and Major Energy Companies.Cash Flows Used in Financing Activities. Cash flows used in financing activities increased by $46.4 million for the year endedDecember 31, 2018. The increase in cash flows used in financing activities was primarily due to increased net paydown of our SeniorCredit Facility, additional dividends paid to holders of Series A Preferred Stock, payments related to the Verde Promissory Note andpayments associated with the acquisition of customers from an affiliate for the year ended December 31, 2018. Cash flows provided byfinancing activities increased by $44.9 million for the year ended December 31, 2017 primarily due to increased net utilization of ourSenior 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 ofSpark HoldCo. 57 Table of ContentsSummary of Contractual ObligationsThe following table discloses aggregate information about our contractual obligations and commercial commitments as ofDecember 31, 2018 (in millions): Total20192020202120222023> 5 yearsOperating leases (1)$1.0$0.6$0.3$0.1$—$—$—Purchase obligations:Pipeline transportation agreements14.66.81.11.11.11.03.5Other purchase obligations (2)10.45.43.31.7———Total purchase obligations$26.0$12.8$4.7$2.9$1.1$1.0$3.5Senior Credit Facility$129.5$—$129.5$—$—$—$—Note payable6.96.9—————Debt$136.4$6.9$129.5$—$—$—$—(1)Included in the total amount are future minimum payments for office leases.(2)The amounts presented here include contracts for billing services and other software agreements to support our operations.Tax Receivable AgreementAs of December 31, 2018, the Company had a Tax Receivable Liability of $27.6 million, which is not reflected in the contractualobligations table above as the estimated timing of payments made under the Tax Receivable Agreement is imprecise by nature,uncertain, and dependent upon a variety of factors, as described in Note 15 "Transactions with Affiliates."Off-Balance Sheet ArrangementsAs of December 31, 2018 we had no material off-balance sheet arrangements.58 Table of ContentsRelated Party TransactionsFor a discussion of related party transactions see Note 15 "Transactions with Affiliates" in the Company’s audited consolidated financialstatements.Critical Accounting Policies and EstimatesOur significant accounting policies are described in Note 2 "Basis of Presentation and Summary of Significant Accounting Policies" toour audited consolidated financial statements. We prepare our financial statements in conformity with accounting principles generallyaccepted in the United States of America and pursuant to the rules and regulations of the SEC, which require us to make estimates andassumptions that affect the amounts reported in the financial statements and accompanying footnotes. Actual results could differ fromthose estimates. We consider the following policies to be the most critical in understanding the judgments that are involved in preparingour financial statements and the uncertainties that could impact our financial condition and results of operations.Revenue Recognition and Retail Cost of RevenuesOur revenues are derived primarily from the sale of natural gas and electricity to retail customers. We also record revenues from sales ofnatural gas and electricity to wholesale counterparties, including affiliates. Revenues are recognized when the natural gas or electricityis delivered. Similarly, cost of revenues is recognized when the commodity is delivered.In each period, natural gas and electricity that has been delivered but not billed by period is estimated. Accrued unbilled revenues arebased on estimates of customer usage since the date of the last meter read and are provided by the utility. Volume estimates are basedon forecasted volumes and estimated customer usage by class. Unbilled revenues are calculated by multiplying these volume estimatesby 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 applicablereporting period. In estimating supply volumes, we consider the effects of historical customer volumes, weather factors and usage bycustomer class. Transmission and distribution delivery fees, where applicable, are estimated using the same method used for sales toretail customers. In addition, other load related costs, such as ISO fees, ancillary services and renewable energy credits are estimatedbased on historical trends, estimated supply volumes and initial utility data. Volume estimates are then multiplied by the supply rate andrecorded as retail cost of revenues in the applicable reporting period. Estimated amounts are adjusted when actual usage is known andbilled.Business CombinationsWhen we acquire a business or a book of customers, we assign and allocate the purchase price to the identifiable assets acquired andliabilities assumed based upon their estimated fair value. Generally, the amount recorded in the financial statements for an acquisition’sassets and liabilities is equal to the purchase price (the fair value of the consideration paid); however, when the purchase price exceedsthe underlying fair value of the net assets acquired, we recognize goodwill. Conversely, a purchase price that is below the fair value ofthe 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 thepurchase price to the individual assets and liabilities and can impact the gross amount and classification of assets and liabilities recordedin our consolidated balance sheets, which can impact the timing and amount of depreciation and amortization expense recorded in anygiven period.In estimating fair value, we use discounted cash flow (“DCF”) projections, recent comparable market transactions, if available, orquoted prices. We consider assumptions that third parties would make in estimating fair value,59 Table of Contentsincluding, but not limited to, the highest and best use of the asset. There is a significant amount of judgment involved in cash-flowestimates, including assumptions regarding market convergence, discount rates, commodity prices, customer attrition, useful lives andgrowth 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 andprices of similar assets when making our best estimate. We also may hire independent appraisers or valuation specialists to help usmake this determination as we deem appropriate under the circumstances. Refer to Note 4 "Acquisitions" for further discussion ofassumptions used in acquisitions.There is a significant amount of judgment in determining the fair value of acquisitions and in allocating the purchase price to individualassets and liabilities. Had different assumptions been used, the fair value of the assets acquired and liabilities assumed could have beensignificantly higher or lower with a corresponding increase or reduction in recognized goodwill, or could have required recognition of abargain purchase.In the case of acquisitions that involve potential future contingent consideration, we record on the date of acquisition a liability equal tothe fair value of the estimated additional consideration we may be obligated to pay in the future. We re-measure this liability eachreporting period and record changes in the fair value as general and administrative expense. Increase or decreases in the fair value ofthe 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 andalternative estimated probabilities surrounding revenue or customer count thresholds could result in different expense related tocontingent consideration.GoodwillAs noted above, Goodwill represents the excess of cost over fair value of the assets of businesses. The goodwill on our consolidatedbalance sheet as of December 31, 2018 is associated with both our Retail Natural Gas and Retail Electricity reporting units. Wedetermine our reporting units by identifying each unit that is engaged in business activities from which it may earn revenues and incurexpenses, has operating results regularly reviewed by the segment manager for purposes of resource allocation and performanceassessment, and has discrete financial information.Goodwill is assessed for impairment whenever events or circumstances indicate that impairment of the carrying value of goodwill islikely, but no less often than annually. Our annual assessment, absent a triggering event is asof October 31 of each year. On October 31, 2018, we elected to perform a qualitative assessment of goodwill in accordance withguidance from ASC 350. This guidance permits an entity to first assess qualitative factors to determine whether it is more likely than notthat the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform thetwo-step goodwill impairment test. If we fail the qualitative test or if we elect to by-pass the qualitative assessment, then we mustcompare our estimate of the fair value of a reporting unit with its carrying value, including goodwill. If the carrying value of thereporting unit exceeds its fair value, we perform the second step of the goodwill impairment test to measure the amount of goodwillimpairment loss to be recorded, as necessary. The second step compares the implied fair value of the reporting unit’s goodwill to thecarrying value, if any, of that goodwill. We determine the implied fair value of the goodwill in the same manner as determining theamount of goodwill to be recognized in a business combination. All of these assessments and calculations, including the determinationof 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 liabilitiesThe Company recognizes the amount of taxes payable or refundable for each tax year. In addition, the Company follows the asset andliability method of accounting for income taxes where deferred tax assets and liabilities are60 Table of Contentsrecognized for the expected future tax consequences of events that have been recognized in the financial statements or tax returns andoperating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxableincome in those years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assetsand liabilities of a change in the tax rates is recognized in income in the period that includes the enactment date. A valuation allowanceis provided for deferred tax assets if it is more likely than not that these items will not be realized.In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all ofthe deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of futuretaxable income during the periods in which those temporary differences become deductible. Management considers the projected futuretaxable income and tax planning strategies in making this assessment. All of these determinations involve estimates and assumptions.Recent Accounting PronouncementsRefer to Note 2 "Basis of Presentation and Summary of Significant Accounting Policies" for a discussion of recent accountingpronouncements.ContingenciesIn the ordinary course of business, we may become party to lawsuits, administrative proceedings and governmental investigations,including regulatory and other matters. Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties andother sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. For adiscussion of the status of current legal and regulatory matters, see Note 14 "Commitment and Contingencies" in the Company’saudited consolidated financial statements.61 Table of ContentsITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKMarket risks relating to our operations result primarily from changes in commodity prices and interest rates, as well as counterpartycredit risk. We employ established risk management policies and procedures to manage, measure, and limit our exposure to these risks.Commodity Price RiskWe hedge and procure our energy requirements from various wholesale energy markets, including both physical and financial marketsand through short and long-term contracts. Our financial results are largely dependent on the margin we are able to realize between thewholesale purchase price of natural gas and electricity plus related costs and the retail sales price we charge our customers for thesecommodities. We actively manage our commodity price risk by entering into various derivative or non-derivative instruments to hedgethe variability in future cash flows from fixed-price forecasted sales and purchases of natural gas and electricity in connection with ourretail energy operations. These instruments include forwards, futures, swaps, and option contracts traded on various exchanges, such asNYMEX 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 connectionwith our asset optimization activities to attempt to generate incremental gross margin by effecting transactions in markets where wehave a retail presence. Generally, any such instruments that are entered into to support our retail electricity and natural gas business arecategorized as having been entered into for non-trading purposes, and instruments entered into for any other purpose are categorized ashaving been entered into for trading purposes.Our net loss on our non-trading derivative instruments, net of cash settlements, was $29.2 million for the year ended December 31,2018.We measure the commodity risk of our non-trading energy derivatives using a sensitivity analysis on our net open position. As ofDecember 31, 2018, our Gas Non-Trading Fixed Price Open Position (hedges net of retail load) was a short position of 391,416MMBtu. An increase of 10% in the market prices (NYMEX) from their December 31, 2018 levels would have increased the fair marketvalue of our net non-trading energy portfolio by $0.1 million. Likewise, a decrease of 10% in the market prices (NYMEX) from theirDecember 31, 2018 levels would have decreased the fair market value of our non-trading energy derivatives by $0.1 million. As ofDecember 31, 2018, our Electricity Non-Trading Fixed Price Open Position (hedges net of retail load) was a long position of 48,125MWhs. An increase of 10% in the forward market prices from their December 31, 2018 levels would have increased the fair marketvalue of our net non-trading energy portfolio by $0.3 million. Likewise, a decrease of 10% in the forward market prices from theirDecember 31, 2018 levels would have decreased the fair market value of our non-trading energy derivatives by $0.3 million.Credit RiskIn many of the utility services territories where we conduct business, POR programs have been established, whereby the local regulatedutility purchases our receivables, and becomes responsible for billing the customer and collecting payment from the customer. Thisservice 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 waswith local regulated utility companies as of December 31, 2018, 2017 and 2016, respectively, all of which had investment grade ratingsas 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 whencollections 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 theseservice programs, we are exposed to credit risk related to payment for services rendered during the time between when the customer istransferred to us by the local regulated utility and the time we return the62 Table of Contentscustomer to the utility for termination of service, which is generally one to two billing periods. We may also realize a loss on fixed-pricecustomers in this scenario due to the fact that we will have already fully hedged the customer's expected commodity usage for the lifeof the contract.In non-POR markets (and in POR markets where we may choose to direct bill our customers), we manage customer credit risk throughformal credit review in the case of commercial customers, and credit score screening, deposits and disconnection for non-payment, inthe case of residential customers. Economic conditions may affect our customers' ability to pay bills in a timely manner, which couldincrease customer delinquencies and may lead to an increase in bad debt expense. Our bad debt expense for the year endedDecember 31, 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 CreditRisk” 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 acounterparty 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-investmentgrade counterparty or otherwise not secured with collateral or a guarantee. The credit worthiness of the remaining exposure with othercustomers was evaluated with no material allowance recorded at December 31, 2018 and 2017.Interest Rate RiskWe are exposed to fluctuations in interest rates under our variable-price debt obligations. At December 31, 2018, we were co-borrowersunder the Senior Credit Facility, under which $129.5 million of variable rate indebtedness was outstanding. Based on the averageamount of our variable rate indebtedness outstanding during the year ended December 31, 2018, a 1% percent increase in interest rateswould 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.63 Table of ContentsItem 8. Financial Statements and Supplementary DataITEM 8.

Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities ExchangeAct of 1934, as amended, as a process designed by, or under the supervision of, our principal executive and principal financial officersand effected by our board of directors, management, and other personnel, to provide reasonable assurance regarding the reliability offinancial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accountingprinciples and includes those policies and procedures that:•Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositionsof the assets;•Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements inaccordance with generally accepted accounting principles, and the receipts and expenditures are being made only inaccordance with authorizations of our management and directors; and•Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition ofour 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, projectionsof any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes inconditions, 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-IntegratedFramework (2013). Based on its assessment, our management concluded the Company’s internal control over financial reporting waseffective as of December 31, 2018.65 Table of ContentsReport of Independent Registered Public Accounting FirmTo the Shareholders and the Board of Directors of Spark Energy, Inc.Opinion on the Financial StatementsWe have audited the accompanying consolidated balance sheet of Spark Energy, Inc. (the Company) as of December 31, 2018, therelated consolidated statement of operations and comprehensive (loss) income, changes in equity, and cash flows for the year endedDecember 31, 2018, and the related notes. 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 theyear ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.Basis for OpinionThese financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on theCompany’s financial statements based on our audit. We are a public accounting firm registered with the Public Company AccountingOversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S.federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit toobtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. TheCompany is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part ofour audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing anopinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to erroror fraud, and performing procedures that respond to those risks.

Basis of Presentation and Summary of Significant Accounting PoliciesBasis of PresentationThe accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principlesgenerally 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. Weaccount for investments over which we have significant influence but not a controlling financial interest using the equity method ofaccounting. All significant intercompany transactions and balances have been eliminated in the consolidated financial statements.Immaterial Corrections to Prior Year Financial InformationThe consolidated balance sheet, income statements, statement of changes in stockholders' equity and our cash flow statements reflectimmaterial adjustments to the historical balances in additional paid in capital, non-controlling interest, deferred tax assets, retainedearnings, income tax expense, net (loss) income attributable to non-controlling interest, and earnings per share for the years endedDecember 31, 2017 and 2016.

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 immaterialcorrections to the allocation of income between non-controlling interests and income available for common shareholders. Ouradjustments had no impact on the manner in which distributions were paid in any current or prior period. The Company evaluated themateriality of the errors from quantitative and qualitative perspectives, and concluded that the errors were immaterial to the Company’sprior period interim and annual consolidated financial statements. Since the revision was not material to any prior period interim orannual consolidated financial statements, no amendments to previously filed interim or annual periodic reports was75 Table of Contentsrequired.

NuDevco Retail is a wholly owned subsidiary of NuDevco RetailHoldings LLC ("NuDevco Retail Holdings"), which is a wholly owned subsidiary of Electric HoldCo, LLC, which is also a whollyowned subsidiary of TxEx.We enter into transactions with and pay certain costs on behalf of affiliates that are commonly controlled by Mr. Maxwell, and theseaffiliates enter into transactions with and pay certain costs on our behalf. We undertake these transactions in order to reduce risk, reduceadministrative 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, employee benefits provided through the Company’s benefit plans, insurance plans,leased office space, certain administrative salaries, management due diligence, recurring management consulting, and accounting, tax,legal, or technology services. Amounts billed under these arrangements are based on services provided, departmental usage, orheadcount, which are considered reasonable by management. As such, the accompanying consolidated financial statements includecosts that have been incurred by the Company and then directly billed or allocated to affiliates, and costs that have been incurred by ouraffiliates and then directly billed or allocated to us, and are recorded net in general and administrative expense on the consolidatedstatements of operations with a corresponding accounts receivable—affiliates or accounts payable—affiliates, respectively, recorded inthe consolidated balance sheets. Additionally, the Company enters into transactions with certain affiliates for sales or purchases ofnatural gas and electricity, which are recorded in retail revenues, retail cost of revenues, and net asset optimization revenues in theconsolidated statements of operations with a corresponding accounts receivable—affiliate or accounts payable—affiliate in theconsolidated balance sheets. The allocations and related estimates and assumptions are described more fully in Note 15 "Transactionswith Affiliates."Cash and Cash EquivalentsCash and cash equivalents consist of all unrestricted demand deposits and funds invested in highly liquid instruments with originalmaturities of three months or less. The Company periodically assesses the financial77 Table of Contentscondition of the institutions where these funds are held and believes that its credit risk is minimal with respect to these institutions.Accounts ReceivableTrade accounts receivable are recorded at the invoiced amount and do not bear interest.The Company accrues an allowance for doubtful accounts based upon estimated uncollectible accounts receivable consideringhistorical collections, accounts receivable aging analysis, credit risk and other factors. The Company writes off accounts receivablebalances 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 ofoperations 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 thenbecomes responsible for billing the customer and collecting payment from the customer (“POR programs”). This POR service results insubstantially all of the Company’s credit risk being linked to the applicable utility, which generally has an investment-grade rating, andnot to the end-use customer. The Company monitors the financial condition of each utility and currently believes such amounts arecollectible. Trade accounts receivable that are part of a local regulated utility’s POR program are recorded on a gross basis in accountsreceivable in the consolidated balance sheets. The discount paid to the local regulated utilities is recorded in general and administrativeexpense 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 andcollected by the Company. The Company bears the credit risk on these accounts and records an appropriate allowance for doubtfulaccounts to reflect any losses due to non-payment by customers. The Company’s customers are individually insignificant andgeographically dispersed in these markets. The Company writes off customer balances when it believes that amounts are no longercollectible and when it has exhausted all means to collect these receivables.InventoryInventory consists of natural gas used to fulfill and manage seasonality for fixed and variable-price retail customer load requirementsand is valued at the lower of weighted average cost or market. Purchased natural gas costs are recognized in the consolidated statementsof operations, within retail cost of revenues, when the natural gas is sold and delivered out of the storage facility using the weightedaverage cost of the gas sold.Customer Acquisition CostsThe 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 millionand $22.1 million were recorded in current assets, and $3.9 million and $6.9 million were recorded in non-current assets. Amortizationof customer acquisition costs were $24.4 million, $21.4 million, and $17.5 million for the years ended December 31, 2018, 2017 and2016, respectively. Customer acquisition costs do not include customer acquisitions through merger and acquisition activities, whichare recorded as customer relationships.Recoverability of customer acquisition costs is evaluated based on a comparison of the carrying amount of such costs to the future netcash flows expected to be generated by the customers acquired, considering specific78 Table of Contentsassumptions for customer attrition, per unit gross profit, and operating costs. These assumptions are based on forecasts and historicalexperience.Customer RelationshipsCustomer contracts recorded as part of mergers or acquisitions are reflected as customer relationships in our balance sheet. TheCompany had capitalized customer relationship of $16.6 million and $18.7 million, net of amortization, as current assets as ofDecember 31, 2018 and 2017, respectively, and $26.4 million and $34.8 million, net of amortization, as non-current assets as ofDecember 31, 2018 and 2017, respectively, related to these intangible assets. These intangibles are amortized on a straight-line basisover the estimated average life of the related customer contracts acquired, which ranges from three to six years.The acquired customer relationships intangibles related to Oasis, CenStar, Provider Companies, Major Energy Companies, PerigeeEnergy LLC, Verde Companies, and HIKO are reflective of the acquired companies’ customer base, and were valued at the respectivedates of acquisition using an excess earnings method under the income approach. Using this method, the Company estimated the futurecash flows resulting from the existing customer relationships, considering attrition as well as charges for contributory assets, such as networking 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 HIKOcustomer relationships are amortized to depreciation and amortization based on the expected future net cash flows by year. Theacquired customer relationship intangibles related to the Major Energy Companies, the Provider Companies and the Verde Companieswere bifurcated between hedged and unhedged and amortized to depreciation and amortization based on the expected future cash flowsby year and expensed to retail cost of revenue based on the expected term of the underlying fixed price contract in each reportingperiod, respectively.Customer relationship amortization expense was $20.3 million, $17.8 million, and $28.6 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 was included in retail costof revenue for those years.We review customer relationships for impairment whenever events or changes in business circumstances indicate the carrying value ofthe intangible assets may not be recoverable. Impairment is indicated when the undiscounted cash flows estimated to be generated bythe intangible assets are less than their respective carrying value. If an impairment exists, a loss is recognized for the difference betweenthe fair value and carrying value of the intangible assets. No impairments of customer relationships were recorded for the years endedDecember 31, 2018, 2017 and 2016.Non-compete agreementsWe capitalize intangible costs associated with non-compete agreements in certain of our acquisitions. Non-compete agreements providethe Company with a certain level of assurance that acquired companies' expected earnings streams will not be disrupted by competitionfrom the companies’ previous owners or members. These non-compete agreements are amortized over their estimated useful life ofthree 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 Companyhad $1.4 million of capitalized costs related to non-compete agreements, of which $1.1 million was current, and of which $0.3 millionwas non-current. Amortization expense was $1.1 million, $1.2 million and $0.9 million for the years ended December 31, 2018, 2017and 2016.TrademarksWe record trademarks as part of our acquisitions which represent the value associated with the recognition and positive reputation of anacquired company to its target markets. This value would otherwise have to be internally developed through significant time andexpense or by paying a third party for its use. These intangibles are amortized over the estimated five-year to ten-year life of thetrademark on a straight-line basis. The fair values of79 Table of Contentstrademark assets were determined at the date of acquisition using a royalty savings method under the income approach. Under thisapproach, the Company estimates the present value of expected cash flows resulting from avoiding royalty payments to use a thirdparty trademark. The Company analyzes market royalty rates charged for licensing trademarks and applied an expected royalty rate to aforecast of estimated revenue, which was then discounted using an appropriate risk adjusted rate of return. As of December 31, 2018and 2017, we had recorded $7.3 million and $8.6 million related to these trademarks in other assets. Amortization expense was $1.3million, $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 theintangible assets may not be recoverable. Impairment is indicated when the undiscounted cash flows estimated to be generated by theintangible assets are less than their respective carrying value. If an impairment exists, a loss is recognized for the difference between thefair 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 CostsCosts incurred in connection with the issuance of long-term debt are capitalized and amortized to interest expense using the straight-linemethod over the life of the related long-term debt. These costs are included in other assets in our consolidated balance sheets.Property and EquipmentThe Company records property and equipment at historical cost. Depreciation expense is recorded on a straight-line method based onestimated useful lives, which range from 2 to 5 years, along with estimates of the salvage values of the assets. When items of propertyand 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 incurred duringthe application development stage of projects such as software configuration, coding, installation of hardware and testing. Costsincurred during the preliminary or post-implementation stage of the project are expensed in the period incurred, including costsassociated with formulation of ideas and alternatives, training and application maintenance. After internal-use software projects arecompleted, the associated capitalized costs are depreciated over the estimated useful life of the related asset. Interest costs incurredwhile developing internal-use software projects are also capitalized. Capitalized interest costs for the years ended December 31, 2018,2017 and 2016 were not material.GoodwillGoodwill represents the excess of cost over fair value of the assets of businesses acquired in accordance with FASB ASC Topic 350Intangibles-Goodwill and Other ("ASC 350"). The goodwill on our consolidated balance sheet as of December 31, 2018 is associatedwith both our Retail Natural Gas and Retail Electricity segments. We determine our segments, which are also considered our reportingunit, by identifying each unit that engaged in business activities from which it may earn revenues and incur expenses, had operatingresults regularly reviewed by the segment manager for purposes of resource allocation and performance assessment, and had discretefinancial information.Goodwill is not amortized, but rather is assessed for impairment whenever events or circumstances indicate that impairment of thecarrying value of goodwill is likely, but no less often than annually as of October 31. We compare our estimate of the fair value of thereporting unit with its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, we comparethe implied fair value of the reporting unit’s goodwill to the carrying value, if any, of that goodwill, the difference of which is recordedas an impairment in the financial statements. In accordance with our accounting policy, we completed our annual assessment ofgoodwill impairment as of October 31, 2018 during the fourth quarter of 2018, using a qualitative assessment approach,80 Table of Contentsand the test indicated no impairment.Treasury StockTreasury stock consists of Company's own stock that has been issued, but subsequently reacquired by the Company. Treasury stockdoes not reduce the number of shares issued but does reduce the number of shares outstanding. These shares are not eligible to receivecash dividends. We use the cost method to account for treasury shares.Equity Method InvestmentsWe use the equity method of accounting to account for investments where we have the ability to exercise significant influence over, butnot control, the investee. Under the equity method of accounting, investments are stated at initial cost and are adjusted for subsequentadditional investments and our share of earnings or losses and distributions. Equity investments are presented on the consolidatedbalance sheet under "Other assets" and our share of their income is reflected as "Interest and other income" on the consolidatedstatements 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 wouldreceive if the investee were to liquidate all of its assets, as valued in accordance with U.S. GAAP, and distribute that cash to theinvestors. 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 investmentfor the period. See Note 17 "Equity Method Investment" for further discussion.Revenues and Cost of RevenuesOur revenues are derived primarily from the sale of natural gas and electricity to customers, including affiliates. Revenues arerecognized by the Company when: (1) persuasive evidence of an exchange arrangement exists, (2) delivery has occurred or serviceshave 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 thecommodity is delivered.Revenues for natural gas and electricity sales are recognized under the accrual method. Natural gas and electricity sales that have beendelivered but not billed by period end are estimated. Accrued unbilled revenues are based on estimates of customer usage since the dateof 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 areadjusted when actual usage is known and billed.Costs for natural gas and electricity sales are similarly recognized under the accrual method. Natural gas and electricity costs that havenot been billed to the Company by suppliers but have been incurred by period end are estimated. The Company estimates volumes fornatural gas and electricity delivered based on the forecasted revenue volumes, estimated transportation cost volumes and estimation ofother costs associated with retail load that varies by commodity utility territory. These costs include items like ISO fees, ancillaryservices 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 transportationtransactions, meet the definition of trading activities and are recorded on a net basis in the consolidated statements of operations in netasset optimization revenues. The Company recorded asset optimization revenues, primarily related to physical sales or purchases ofcommodities, of $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 $109.2 million, $179.0 million and $133.6 million for the yearsended December 31, 2018, 2017 and 2016, respectively, which are presented on a net basis in asset optimization revenues.81 Table of ContentsNatural Gas ImbalancesThe consolidated balance sheets include natural gas imbalance receivables and payables, which primarily result when customersconsume more or less gas than has been delivered by the Company to local distribution companies (“LDCs”). The settlement of naturalgas 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 imbalancereceivable of $0.8 million and $0.7 million in other current assets on the consolidated balance sheets as of December 31, 2018 and2017, respectively. The Company recorded an imbalance payable of $0.3 million and $1.0 million in other current liabilities on theconsolidated balance sheets as of December 31, 2018 and 2017, respectively.Derivative InstrumentsThe Company uses derivative instruments such as futures, swaps, forwards and options to manage the commodity price risks of itsbusiness operations.All derivatives are recorded in the consolidated balance sheets at fair value. Derivative instruments representing unrealized gains arereported as derivative assets while derivative instruments representing unrealized losses are reported as derivative liabilities. We offsetamounts in the consolidated balance sheets for derivative instruments executed with the same counterparty where we have a masternetting 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 inearnings in net asset optimization revenues.To manage the retail business, the Company holds derivative instruments that are not for trading purposes and are not designated ashedges for accounting purposes. Changes in the fair value of and amounts realized upon settlement of derivative instruments not heldfor trading purposes are recognized in retail costs of revenues.Income TaxesThe Company follows the asset and liability method of accounting for income taxes where deferred tax assets and liabilities arerecognized for the expected future tax consequences of events that have been recognized in the financial statements or tax returns andoperating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxableincome in those years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assetsand liabilities of a change in the tax rates is recognized in income in the period that includes the enactment date. A valuation allowanceis provided for deferred tax assets if it is more likely than not that these items will not be realized. Amounts owed or refundable oncurrent 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 ofthe deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of futuretaxable income during the periods in which those temporary differences become deductible. Management considers the projected futuretaxable income and tax planning strategies in making this assessment.The Company recognizes interest and penalties related to unrecognized tax benefits within the provision for income taxes on continuingoperations in our consolidated statements of operations.Earnings per ShareBasic 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 B82 Table of Contentscommon shares are not included in the calculation of basic earnings per share because they are not participating securities and have noeconomic interest in us. Diluted earnings per share is similarly calculated except that the denominator is increased for potentiallydilutive securities. We use the treasury stock method to determine the potential dilutive effect of our outstanding unvested restrictedstock units and use the if-converted method to determine the potential dilutive effect of our Class B common stock.Non-controlling InterestNet income attributable to non-controlling interest represents the Class B Common stockholders' interest in income and expenses of theCompany. The weighted average ownership percentages for the applicable reporting period are used to allocate the income (loss)before income taxes to each economic interest owner.Commitments and ContingenciesLiabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded when it isprobable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with losscontingencies are expensed as incurred.Recent Accounting PronouncementsOn January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize theamount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. We adopted thestandard utilizing the full retrospective approach, and the adoption had no impact on our total revenues and operating income for theyears ended December 31, 2018, 2017 and 2016. The standard requires expanded disclosures regarding the qualitative and quantitativeinformation of an entity's nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. SeeNote 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 ("ASU2017-01"). ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluatingwhether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. We utilized ASU 2017-01 inevaluating all acquisitions occurring after the date of adoption.On January 1, 2018, we adopted ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts andCash Payments ("ASU 2016-15"). ASU 2016-15 provides guidance on the presentation and classification of specific cash flow issues inthe statement of cash flows, including contingent consideration payments made after a business combination. We applied this guidanceusing a retrospective transition method for each period presented. Because of the change in accounting guidance, we reclassifiedacquisition related payments of approximately $1.8 million and $0.8 million from cash flows from investing activities to cash flowsfrom operating activities for the years ended December 31, 2017 and December 31, 2016, respectively. We reclassified acquisitionrelated payments of approximately $18.4 million and $2.0 million from cash flows from investing activities to cash flows fromfinancing activities for the years ended December 31, 2017 and December 31, 2016, respectively.In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Transfers of Assets Other Than Inventory ("ASU 2016-16"), whichstates an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when thetransfer occurs and not when the asset has been sold to an outside party. The amendments in this guidance eliminate exceptions forintra-entity transfer of an asset, such as intellectual property and property, plant, and equipment. ASU 2016-16 is effective on amodified retrospective basis through a cumulative-effect adjustment directly to retained earnings for annual reporting periods beginningafter December 15, 2017. We adopted ASU 2016-16 effective January 1, 2018, with no cumulative-effect adjustment. 83 Table of ContentsNew Accounting Standards Being Evaluated But Not Yet AdoptedBelow are accounting standards that have been issued, but not yet been adopted by the Company at December 31, 2018.In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). Under this new guidance, lessees will berequired to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of greaterthan twelve months. The guidance requires qualitative disclosures along with certain specific quantitative disclosures for both lesseesand lessors. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases (“ASU 2018-10”), andASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”), to provide additional guidance for the adoption ofTopic 842. The ASU and its related amendments are effective for fiscal years beginning after December 15, 2018, with early adoptionpermitted, and are effective for interim periods in the year of adoption. The ASU should be applied using a modified retrospectiveapproach, which requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented with anoption to use certain practical expedients, which we expect to use. We have evaluated the impact of this new guidance and reviewedlease or possible lease contracts and evaluated contract related processes. We believe the primary impact will be related to therecognition of right-of-use assets and liabilities for our real estate operating leases in the range of approximately $1.0 million to $1.5million.In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for GoodwillImpairment ("ASU 2017-04"). ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from thegoodwill impairment test. Under this update, an entity should perform its annual or interim goodwill impairment test by comparing thefair value of a reporting unit with its carrying amount, including goodwill. An entity should recognize an impairment charge for theamount by which the carrying amount exceeds the reporting unit's fair value. However, the loss recognized should not exceed the totalamount of goodwill allocated to that reporting unit. ASU 2017-04 should be applied on a prospective basis and is effective for annualor any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim orannual 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.In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Non-employeeShare-Based Payment Accounting ("ASU 2018-07"). ASU 2018-07 primarily expands the scope of Topic 718 to include share-basedpayment transactions for acquiring goods and services from non-employees. ASU 2018-07 is effective for fiscal years beginning afterDecember 15, 2018, including interim periods within that fiscal year. We adopted ASU 2018-07 effective January 1, 2019, and theadoption of this standard did not have a material impact on the Company's consolidated financial statements.3. RevenuesOur revenues are derived primarily from the sale of natural gas and electricity to customers, including affiliates. Revenue is measuredbased upon the quantity of gas or power delivered at prices contained or referenced in the customer's contract, and excludes any salesincentives (e.g. rebates) and amounts collected on behalf of third parties (e.g. sales tax).We record gross receipts taxes on a gross basis in retail revenues and retail cost of revenues. During the year ended December 31,2018, 2017 and 2016 our retail revenues included gross receipts taxes of $6.9 million, $6.4 million and $3.9 million respectively.During the year ended December 31, 2018, 2017 and 2016, our retail cost of revenues included gross receipts taxes of $9.9 million,$9.0 million and $5.3 million, respectively.84 Table of ContentsOur revenues also include asset optimization activities. Asset optimization activities consist primarily of purchases and sales of gas thatmeet the definition of trading activities per FASB ASC Topic 815, Derivatives and Hedging. They are therefore excluded from thescope of Revenue from Contracts with Customers (Topic 606).The following is a description of our principal revenue generating activities.Retail ElectricityRevenues 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 besold as fixed or variable rate products. The typical length of a contract to provide electricity is 12 months. Customers are billed andtypically 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 arecalculated by multiplying these volume estimates by the applicable rate by customer class (residential or commercial). Estimatedamounts are adjusted when actual usage is known and billed.Retail Natural GasRevenues for natural gas 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. Natural gas products may besold as fixed-price or variable-price products. The typical length of a contract to provide natural gas is 12 months. Customers are billedand typically pay at least monthly, based on usage. Natural gas sales that have been delivered but not billed by period end are estimatedand recorded as accrued unbilled revenues based on estimates of customer usage since the date of the last meter read provided by theutility. Volume estimates are based on forecasted volumes and estimated residential and commercial customer usage. Unbilled revenuesare calculated by multiplying these volume estimates by the applicable rate by customer class (residential or commercial).

AcquisitionsAcquisition of the Provider CompaniesIn August 2016, we completed the purchase of all of the outstanding membership interests of the Provider Companies forapproximately $34.1 million, which included $1.3 million in working capital, subject to adjustments. The acquisition also included anearnout provision of up to $9.0 million, which was initially valued at $4.8 million as of the purchase date, and which was to be paid byJune 30, 2017, subject to the achievement of certain performance targets (the "Provider Earnout"). See Note 11 "Fair ValueMeasurements" for further information on the Provider Earnout. The Provider Companies serve electrical customers in Maine, NewHampshire and Massachusetts.86 Table of ContentsThe acquisition of the Provider Companies was accounted for under the acquisition method of accounting. The allocation of purchaseconsideration was based upon the estimated fair value of the tangible and identifiable intangible assets acquired and liabilities assumedin the acquisition. The allocation was made to major categories of assets and liabilities based on management’s best estimates, andsupported by independent third-party analyses. The excess of the purchase price over the estimated fair value of tangible and intangibleassets acquired and liabilities assumed was allocated to goodwill. The purchase price allocation for the acquisition of the ProviderCompanies was finalized as of December 31, 2016 as follows: Final Purchase PriceAllocationCash $431Net working capital, net of cash acquired 812Intangible assets—customer relationships and non-compete agreements 24,417Intangible assets—trademark 529Goodwill 26,040Fair value of derivative liabilities (18,163)Total $34,066The fair values of intangible assets were measured primarily based on significant inputs that are not observable in the market and thusrepresent a Level 3 fair value measurement. The fair value of derivative liabilities were measured by utilizing readily available quotedmarket prices and non-exchange-traded contracts fair valued using market price quotations available through brokers or over-the-counter and on-line exchanges and represent a Level 2 fair value measurement. See Note 11 "Fair Value Measurements" for furtherdiscussion on the fair values hierarchy. The valuation of intangible assets and goodwill are discussed later in this note. The ProviderEarnout was settled at $5.5 million in 2017, including interest.The Company’s consolidated statements of operations for the year ended December 31, 2016 included $46.8 million of revenue and$12.8 million of losses from operations related to the operations of the Provider Companies.Acquisition of the Major Energy CompaniesIn August 2016, we completed the purchase of all of the outstanding membership interests of the Major Energy Companies, which areretail energy companies operating in Connecticut, Illinois, Maryland (including the District of Columbia), Massachusetts, New Jersey,New York, Ohio, and Pennsylvania across 43 utilities, from NG&E. The total purchase price was $64.1 million, which included $5.2million in working capital; an assumed litigation reserve of $5.0 million, and up to $35.0 million in installment and earnout payments,valued at $13.1 million as of NG&E's April 15, 2016 purchase date, to be paid to the previous members of the Major EnergyCompanies, in annual installments on March 31, 2017, 2018 and 2019, subject to the achievement of certain performance targets (the“Major Earnout”). Additionally, the Company was potentially obligated to issue up to 400,000 shares of Class B common stock (and acorresponding number of Spark HoldCo units) to NG&E, subject to the achievement of certain performance targets, which were valuedat $0.8 million as of the purchase date (the "Stock Earnout"). No shares were subsequently issued under the Stock Earnout provisions.See Note 11 "Fair Value Measurements" for further information on the Major Earnout and Stock Earnout.The acquisition of the Major Energy Companies from NG&E was treated as a transfer of interests in entities under common control.Accordingly, the impact from the assets acquired and liabilities assumed were based on those values and results from the date NG&Eacquired the Major Energy Companies, which was April 15, 2016. The fair value allocation of the net assets acquired was as follows (inthousands):87 Table of Contents Final Purchase Price AllocationCash $17,368Property and equipment 14Intangible assets—customer relationships & non-compete agreements 24,271Other assets—trademarks 4,973Non-current deferred tax assets 1,042Goodwill 34,988Net working capital, net of cash acquired (6,746)Fair value of derivative liabilities (7,260)Total $68,650In December 2016, certain executives of the Major Energy Companies exercised a change of control provision under employmentagreements with the Major Energy Companies. As a result, the Company recorded employment contract termination costs of $4.1million as of December 31, 2016. The Company paid employment contract termination costs totaling approximately $1.4 million and$2.5 million during the years ended December 31, 2018 and 2017, respectively, with the remaining costs of $0.2 million recorded as aliability as of December 31, 2018.The Major Energy Companies contributed revenues of $125.6 million and earnings of $1.3 million to the Company for the year endedDecember 31, 2016. The following unaudited pro forma revenue and earnings summary presents consolidated information of theCompany for 2016 as if the acquisition had occurred on January 1, 2015 (in thousands): Year Ended December 31, 20162015Revenue$603,673$547,381Earnings$15,776$15,460The pro forma results are not necessarily indicative of our consolidated results of operations that actually would have been realized hadthe companies operated on a combined basis during the period presented.

The pro forma results include adjustments related toamortization of acquired intangibles, and certain accounting policy alignments as well as direct and incremental acquisition related costsreflected in the historical financial statements. The purchase price allocation was used to prepare the pro forma adjustments.Acquisition of PerigeeIn April 2017, we acquired all of the outstanding membership interests of Perigee Energy, LLC, a Texas limited liability company("Perigee"), with operations across 14 utilities in Connecticut, Delaware, Massachusetts, New York and Ohio from our affiliate, NG&E.The purchase price for Perigee from NG&E was approximately $4.1 million, which consisted of a base price of $2.0 million, $0.2million additional customer option payment, and $1.9 million in working capital, subject to adjustments. The acquisition was treated asa transfer of equity interests between entities under common control, and accordingly, the assets acquired and liabilities assumed werebased on their historical value as of the date. NG&E acquired Perigee, which was on February 3, 2017, and the fair value of the netassets acquired was as follows (in thousands):88 Table of Contents Final Purchase Price AllocationCash$23Intangible assets—customer relationships1,100Goodwill1,540Net working capital, net of cash acquired2,085Fair value of derivative liabilities(443)Total$4,305The Perigee acquisition did not have a material impact on our financial position or results of operations.Acquisition of VerdeIn July 2017, we acquired, through our subsidiary CenStar Energy Corp. ("CenStar"), all of the outstanding membership interests andstock in a group of companies (the "Verde Companies") from Verde Energy USA Holdings, LLC (the “Seller”). Total consideration wasapproximately $90.7 million, of which $20.1 million represented positive net working capital, as adjusted. We also entered into anagreement to pay an additional amount based on achievement by the Verde Companies of certain performance targets over the 18month period following closing of the acquisition (the "Verde Earnout"). The Verde Earnout was initially valued at $5.4 million. Theacquisition of the Verde Companies was accounted for under the acquisition method. The allocation of purchase consideration wasbased upon the estimated fair value of the tangible and identifiable intangible assets acquired and liabilities assumed in the acquisitionbased on management's best estimates, and was supported by independent third-party analyses. The excess of the purchase price overthe estimated fair value of tangible and intangible assets acquired and liabilities assumed was allocated to goodwill.

In January 2018, we settled the Verde Earnout by issuing a $5.9 million note payable tothe Seller.The Verde Companies contributed revenues of $76.0 million and earnings of $1.2 million to the Company for the year endedDecember 31, 2017.The following unaudited pro forma revenue and earnings summary presents consolidated information of the Company as if theacquisition had occurred on January 1, 2016 (in thousands):89 Table of Contents Year Ended December 31, 20172016Revenues$868,415$716,696Earnings$18,047$17,860The pro forma results are not necessarily indicative of our consolidated results of operations that actually would have been realized hadthe companies operated on a combined basis during the periods presented. The pro forma results above include actual results and costsas well as adjustments primarily related to amortization of acquired intangibles, and certain accounting policy alignments as well asdirect and incremental acquisition related costs reflected in the historical financial statements. Our initial purchase price allocation wasused to prepare the pro forma adjustments.Acquisition of HIKOIn March 2018, we entered into a Membership Interest Purchase Agreement under which we acquired all of the membership interests ofHIKO Energy, LLC ("HIKO"), a New York limited liability company, for a total purchase price of $6.0 million in cash, plus workingcapital. At the time of acquisition, HIKO had a total of approximately 29,000 RCEs located in 42 markets in seven states. Theacquisition was accounted for under the acquisition method. Our preliminary allocation of the purchase price was based upon theestimated fair value of the tangible and identified intangible assets acquired and liabilities assumed in the acquisition. The preliminaryallocation was made based on management’s best estimates, and supported by independent third-party analyses. The allocation of thepurchase consideration is as follows (in thousands): Preliminary PurchasePrice Allocation2018 Adjustments (1)Purchase Price Allocationas of December 31, 2018Cash and restricted cash$309$66$375Intangible assets—customer relationships6,205(174)6,031Net working capital, net of cash acquired9,041(576)8,465Fair value of derivative liabilities(205)—(205)Total$15,350$(684)$14,666(1) Changes to the purchase price allocation were due to an agreement to settle the working capital balances with HIKO sellers per the purchase agreement.Our condensed consolidated statements of operations for the twelve months ended December 31, 2018 included $15.3 million ofrevenue 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. Acquired customer relationships were reflective of the acquired companies' customer bases, and were valuedusing an excess earnings method under the income approach. Using this method, we estimated the future cash flows resulting from theexisting 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.In acquisitions where we acquired commodity contracts that we could match to fixed-price contracts, customer relationships werebifurcated between unhedged and hedged and are being amortized based on the expected term of the underlying fixed-price contractacquired in each reporting period, respectively.Non-compete Agreements. The fair value of non-compete agreements were determined using the differential value approach. Under thisapproach, we estimated the present value of expected future cash flows of the business with90 Table of Contentsand without the non-compete agreement. The difference in discounted cash flows was then adjusted by probability factors related to thelikelihood 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 theacquired company to target markets. The fair value of trademarks was valued using a royalty savings method under the incomeapproach. The value was based on the savings we would realize from owning the trademark rather than paying a royalty for the use ofthat trademark. Under this approach, we estimate the present value of the expected cash flows resulting from avoiding royalty paymentsto use a third party trademark. In the Verde acquisition, we analyzed market royalty rates charged for licensing trademarks and appliedan expected royalty rate to a forecast of estimated revenue, which was then discounted using an appropriate risk adjusted rate of return.Goodwill. The excess of the purchase consideration over the estimated fair value of the amounts initially assigned to the identifiableassets acquired and liabilities assumed was recorded as goodwill. Goodwill arose on the acquisitions of the Provider Companies, VerdeCompanies and Perigee primarily due to the value of their assembled workforce, proprietary sales channels, and/or access to new utilityservice territories. Goodwill arose on the acquisition of the Major Energy Companies primarily due to the value of the Major EnergyCompanies brand strength, established vendor relationships and access to new utility service territories. Goodwill recorded inconnection with these acquisitions is deductible for income tax purposes because these were acquisitions of all of the assets of thecompanies.Customer Acquisitions. We also, from time to time, acquire books of customers from affiliated and non-affiliated parties. Theseacquisitions do not involve an allocation of the purchase price but rather are recorded as customer relationships.Acquisition of customers from PerigeeIn April 2017, we acquired approximately 44,000 RCEs from the original owner of Perigee. During 2017, we paid $7.5 million forcustomers transferred.Acquisition from Related PartiesIn March 2018, we entered into an asset purchase agreement with our affiliate, NG&E, pursuant to which we agreed to acquire upto 50,000 RCEs for a cash purchase price of $250 for each RCE, or up to $12.5 million in the aggregate. These customers begantransferring after April 1, 2018 and are located in 24 markets in 8 states. For the year ended December 31, 2018, we paid NG&E $8.8million under the terms of the purchase agreement for approximately 35,000 RCEs. We do not anticipate any additional customertransfers or consideration will be paid on this transaction. The acquisition was treated as a transfer of assets between entities undercommon control, and accordingly, the assets were recorded at NG&E's historical value at the date of transfer, which was $1.7 million.The transaction resulted in $7.1 million recorded in equity as a net distribution to affiliate as of December 31, 2018. Of the $8.8 millionpaid to NG&E, $1.7 million was an investing cash outflow and remaining $7.1 million was deemed a distribution to our non-controllinginterest and classified as financing activity.Acquisitions of Customer BooksIn October 2018, we entered into an asset purchase agreement pursuant to which we would acquire up to 60,000 RCEs from StarionEnergy Inc., Starion Energy NY Inc. and Starion Energy PA Inc. for a cash purchase price of up to a maximum of $10.7 million. Thesecustomers began transferring in December 2018, and are located in our existing markets.As part of the acquisition, we funded an escrow account, the balance of which is reflected as restricted cash in our consolidated balancesheet. As of December 31, 2018, the balance in the account was $8.6 million, and these funds will be released to the seller as acquiredcustomers transfer from the seller to the Company in accordance with the91 Table of Contentsasset purchase agreement, and any unallocated balance will be returned to the Company once the acquisition is complete.5. EquityNon-controlling InterestWe hold an economic interest and are the sole managing member in Spark HoldCo, with affiliates of our Founder and majorityshareholder holding the remaining economic interests in Spark HoldCo. As a result, we consolidate the financial position and results ofoperations of Spark HoldCo and reflect the economic interests owned by these affiliates as a non-controlling interest. The Company andaffiliates owned the following economic interests in Spark HoldCo at December 31, 2017 and December 31, 2018, respectively.The CompanyAffiliated OwnersDecember 31, 201738.12%61.88%December 31, 201840.53%59.47%The Spark HoldCo Third Amended and Restated Limited Liability Company Agreement provides that if the Company issues a newshare of Class A common stock, par value $0.01 per share (the "Class A common stock"), Series A Preferred Stock (as defined below),or other equity security of the Company (other than shares of Class B common stock, par value $0.01 per share ("Class B commonstock"), and excluding issuances of Class A common 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 equitysecurity. As a result, the number of Spark HoldCo units held by the Company always equals the number of shares of Class A commonstock, Series A Preferred Stock or such other equity securities of the Company outstanding.Each share of Class B common stock has no economic rights but entitles the holder to one vote on all matters to be voted on bystockholders generally. Holders of Class A common stock and Class B common stock vote together as a single class on all matterspresented to our stockholders for their vote or approval, except as otherwise required by applicable law or by our certificate ofincorporation.We adjust the balances in additional paid in capital and non-controlling interest in our consolidated statements of stockholders’ equityand our balance sheet at the end of each balance sheet period to reflect the amounts the respective owners of our Class A and Class Bcommon stock would receive if the assets of our subsidiary, Spark HoldCo were sold, and the liabilities were settled at their recordedbook values as of each respective balance sheet date. These adjustments for changes in ownership interests do not impact the mannerin which income is allocated or the manner in which distributions are paid to Class A or Class B shareholders.The Class B holders have the right to exchange (the “Exchange Right”) all or a portion of their Spark HoldCo units (together with acorresponding number of shares of Class B common stock) for Class A common stock (or cash at Spark Energy, Inc.’s or SparkHoldCo’s election (the “Cash Option”)) at an exchange ratio of one share of Class A common stock for each Spark HoldCo unit (andcorresponding share of Class B common stock) exchanged. In addition, Class B holders have the right, under certain circumstances, tocause the Company to register the offer and resale of such owners' shares of Class A common stock obtained pursuant to the ExchangeRight.92 Table of ContentsThe following table summarizes the portion of net income and income tax expense (benefit) attributable to non-controlling interest (inthousands):201820172016 Net (loss) income allocated to non-controlling interest$(12,140)$55,068$52,300Income tax expense (benefit) allocated to non-controlling interest1,066(731)1,071Net (loss) income attributable to non-controlling interest$(13,206)$55,799$51,229Stock SplitIn May 2017, the Company authorized and approved a two-for-one stock split of the Company's issued Class A common stock andClass B common stock, which was effected through a stock dividend (the "Stock Split"). Shareholders of record at the close of businesson June 5, 2017 were issued one additional share of Class A common stock or Class B common stock of the Company for each shareof Class A common stock or Class B common stock, respectively, held by such shareholder on that date. Such additional shares ofClass A common stock or Class B common stock were distributed on June 16, 2017. All shares and per share amounts in this reporthave been retrospectively restated to reflect the Stock Split.Issuance of Class A Common Stock Upon Vesting of Restricted Stock UnitsFor the years ended December 31, 2018, 2017, and 2016, 394,243, 356,014, and 395,056, respectively of restricted stock units vested,with 258,076, 241,965, and 305,872, respectively of shares of common stock distributed to the holders of these units. Differencesbetween shares vested and issued were a result of 136,167, 114,049, and 89,184 shares of common stock withheld by the Company tocover taxes owed on the vesting of such units.Conversion of Class B Common Stock to Class A Common StockIn 2018 and 2016, holders of Class B common stock exchanged 685,126 and 6,450,000 respectively, of their Spark HoldCo units(together with a corresponding number of shares of Class B common stock) for shares of Class A common stock at an exchange ratio ofone share of Class A common stock for each Spark HoldCo unit (and corresponding share of Class B common stock) exchanged.Dividends on Class A Common StockDuring the years ended December 31, 2018, 2017, and 2016, we paid dividends on our Class A Common Stock of $9.8 million, $9.5million, and $8.4 million. This dividend represented an annual rate of $0.725 per share on each share of Class A common stock.On January 17, 2019, the Company declared a dividend of $0.18125 per share to holders of record of our Class A common stock onMarch 1, 2019 and payable on March 15, 2019.Issuance of Class B Common StockIn August 2016, the Company issued 1,399,484 shares of Class B common stock to an affiliate in connection with the acquisition of theProvider Companies and also issued 4,000,000 shares of Class B common stock to the affiliate in connection with the acquisition ofMajor Energy Companies.Preferred StockThe Company has 20,000,000 shares of authorized preferred stock for which there are 3,707,256 and 1,704,339 issued and outstandingshares at December 31, 2018 and 2017. See Note 6 "Preferred Stock" for a further discussion of preferred stock.93 Table of ContentsConversion of CenStar and Oasis NotesIn January 2017, several notes issued in connection with our acquisitions of CenStar and Oasis in 2016 were converted into 1,035,642shares of Class B common stock (and related Spark HoldCo units). Refer to Note 10 "Debt" for further discussion.Earnings Per ShareBasic earnings per share (“EPS”) is computed by dividing net income attributable to stockholders (the numerator) by the weighted-average number of Class A common shares outstanding for the period (the denominator). Class B common shares are not included inthe calculation of basic earnings per share because they are not participating securities and have no economic interests. Diluted earningsper share is similarly calculated except that the denominator is increased by potentially dilutive securities. The following table presentsthe computation of basic and diluted (loss) earnings per share for the years ended December 31, 2018, 2017, and 2016 (in thousands,except per share data):Year Ended December 31, 201820172016Net income attributable to Spark Energy, Inc. stockholders$(1,186)$19,245$14,444Less: Dividend on Series A preferred stock8,1093,038—Net (loss) income attributable to stockholders of Class A common stock$(9,295)$16,207$14,444 Basic weighted average Class A common shares outstanding13,39013,14311,402Basic (loss) earnings per share attributable to stockholders$(0.69)$1.23$1.27 Net (loss) income attributable to stockholders of Class A common stock$(9,295)$16,207$14,444Effect of conversion of Class B common stock to shares of Class A common stock———Effect of conversion of convertible subordinated notes into shares of Class B commonstock and shares of Class B common stock into shares of Class A common stock (1)——(310)Diluted net (loss) income attributable to stockholders of Class A common stock$(9,295)$16,207$14,134 Basic weighted average Class A common shares outstanding13,39013,14311,402Effect of dilutive Class B common stock———Effect of dilutive convertible subordinated notes into shares of Class B common stock andshares of Class B common stock into shares of Class A common stock——1,010Effect of dilutive restricted stock units—203278Diluted weighted average shares outstanding13,39013,34612,690 Diluted (loss) earnings per share attributable to stockholders$(0.69)$1.21$1.11(1) The CenStar Note and Oasis Note converted into 269,462 and 766,180 shares of Class B common stock on January 8, 2017, and January 31, 2017, respectively.The computation of diluted earnings per share for the year ended December 31, 2018 excludes 20.8 million shares of Class B commonstock and 0.9 million restricted stock units because the effect of their conversion was antidilutive. The Company's outstanding shares ofSeries A Preferred Stock were not included in the calculation of diluted earnings per share because they contain only contingentredemption provisions which have not occurred.Variable Interest Entity94 Table of ContentsSpark HoldCo is a variable interest entity due to its lack of rights to participate in significant financial and operating decisions and itsinability to dissolve or otherwise remove its management. Spark HoldCo owns all of the outstanding membership interests in each ofour operating subsidiaries. We are the sole managing member of Spark HoldCo, manage Spark HoldCo's operating subsidiaries throughthis managing membership interest, and are considered the primary beneficiary of Spark HoldCo.

Derivative InstrumentsWe are exposed to the impact of market fluctuations in the price of electricity and natural gas, basis differences in the price of naturalgas, storage charges, RECs, capacity charges from independent system operators, and other ancillary costs. We use derivativeinstruments in an effort to manage our cash flow exposure to these risks. These instruments are not designated as hedges for accountingpurposes, and accordingly, changes in the market value of these derivative instruments are recorded in the cost of revenues. As part ofour strategy to optimize pricing in our natural gas related activities, we also manage a portfolio of commodity derivative instrumentsheld for trading purposes. Our commodity trading activities are subject to limits within our Risk Management Policy. For thesederivative 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 withthe same counterparty under a master netting arrangement. Our derivative contracts include transactions that are executed both on anexchange and centrally cleared, as well as over-the-counter, bilateral contracts that are transacted directly with third parties. To theextent we have paid or received collateral related to the derivative assets or liabilities, such amounts would be presented net against therelated 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 financialinstrument;•Swap agreements, which require payments to or from counterparties based upon the differential between two prices for apredetermined 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 or for which wemade 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,•Natural gas transportation contracts and storage agreements.Volumes Underlying Derivative TransactionsThe following table summarizes the net notional volumes of our open derivative financial instruments accounted for at fair value,broken out by commodity.

Fair Value MeasurementsFair 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 transactionbetween market participants at the measurement date. Fair values are based on assumptions that market participants would use whenpricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations.This includes the credit standing of counterparties involved and the impact of credit enhancements.We apply fair value measurements to our commodity derivative instruments and contingent payment arrangements based on thefollowing 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 primarilyconsist 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 assetor liability, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similarassets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability, andinputs that are derived from observable market data by correlation or other means. Instruments categorized in Level 2primarily include non-exchange traded derivatives such as over-the-counter commodity forwards and swaps andoptions.•Level 3—Unobservable inputs for the asset or liability, including situations where there is little, if any, observablemarket activity for the asset or liability. The Level 3 category includes estimated earnout obligations related to ouracquisitions.105 Table of ContentsAs the fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservabledata (Level 3), the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuringfair value. These levels can change over time. In some cases, the inputs used to measure fair value might fall in different levels of thefair value hierarchy. In these cases, the lowest level input that is significant to a fair value measurement in its entirety determines theapplicable level in the fair value hierarchy.Other Financial InstrumentsThe carrying amount of cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities recorded in thecondensed consolidated balance sheets approximate fair value due to the short-term nature of these items. The carrying amounts of theSenior Credit Facility recorded in the condensed consolidated balance sheets approximates fair value because of the variable rate natureof interest on the borrowings thereunder, and are considered Level 2 measurements because interest rates charged are similar to otherfinancial instruments with similar terms and maturities. The fair value of our convertible subordinated notes to affiliates and the payablepursuant to tax receivable agreement—affiliate is not determinable for accounting purposes due to the affiliated nature and terms of theassociated agreements with the affiliate.Assets and Liabilities Measured at Fair Value on a Recurring BasisThe following tables present assets and liabilities measured and recorded at fair value in our consolidated balance sheets on a recurringbasis by and their level within the fair value hierarchy (in thousands):Level 1Level 2Level 3TotalDecember 31, 2018 Non-trading commodity derivative assets$104$9,821$—$9,925Trading commodity derivative assets44596—640Total commodity derivative assets$148 $10,417 $— $10,565Non-trading commodity derivative liabilities$(352)$(5,685)$—$(6,037)Trading commodity derivative liabilities(75)(472)—(547)Total commodity derivative liabilities$(427) $(6,157) $— $(6,584)Contingent payment arrangement$— $— $1,328 $1,328Level 1Level 2Level 3TotalDecember 31, 2017 Non-trading commodity derivative assets$158$33,886$—$34,044Trading commodity derivative assets—456—456Total commodity derivative assets$158 $34,342 $— $34,500Non-trading commodity derivative liabilities$(387)$(950)$—$(1,337)Trading commodity derivative liabilities(555)(237)—(792)Total commodity derivative liabilities$(942) $(1,187) $— $(2,129)Contingent payment arrangement$— $— $(4,650) $(4,650)We had no transfers of assets or liabilities between any of the above levels during the years ended December 31, 2018, 2017 and 2016.Our derivative contracts include exchange-traded contracts valued utilizing readily available quoted market prices and non-exchange-traded contracts valued using market price quotations available through brokers or over-the-counter and on-line exchanges. In addition,in determining the fair value of our derivative contracts, we apply a credit risk valuation adjustment to reflect credit risk, which iscalculated based on our or the counterparty’s historical credit risks. As of December 31, 2018 and 2017, the credit risk valuationadjustment was not material.106 Table of ContentsThe contingent payment arrangements referred to above reflect estimated earnout obligations incurred in relation to our acquisition ofthe Major Energy Companies in 2016.Contingent Payment ArrangementsThe following tables present a roll forward of our contingent payment arrangements, which are measured at fair value on a recurringbasis using significant unobservable inputs (Level 3):Major Earnout andStock EarnoutProvider EarnoutVerde EarnoutTotalFair Value at December 31, 2016$17,760$4,893$—$22,653Purchase price consideration$—$—$5,400$5,400Change in fair value of contingent consideration, net(9,555)500347(8,708)Accretion of contingent earnout consideration(included within interest expense)3,8481071534,108Payments and settlements (1)(7,403)(5,500)(5,900)(18,803)Fair Value at December 31, 2017$4,650$—$—$4,650Change in fair value of contingent consideration, net$(1,715)$—$—$(1,715)Payments and settlements(1,607)——(1,607)Fair Value at December 31, 2018$1,328$—$—$1,328(1) Payments and settlements include pay downs at maturity and the termination of the Verde Earnout liability, which was replaced with the Verde Earnout Termination Note. Seediscussion above and in Note 10 "Debt."The Major Earnout is based on the achievement by the Major Energy Companies of certain performance targets over a 33 month periodfollowing 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 levelof performance targets attained, as defined by the Major Purchase Agreement. The Stock Earnout obligation was contingent upon theMajor Energy Companies achieving the Major Earnout's performance target ceiling, thereby earning the maximum Major Earnoutpayments. If the Major Energy Companies earned such maximum Major Earnout payments, NG&E would be entitled to additionalconsideration up to a maximum of 400,000 shares of Class B common stock (and a corresponding number of Spark HoldCo units). Indetermining the fair value of the Major Earnout and the Stock Earnout, we forecasted certain expected performance targets andcalculated 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.The Provider Earnout was based on achievement by the Provider Companies of a certain customer count criteria over a nine monthperiod following the closing of the Provider Companies acquisition. The sellers of the Provider Companies were entitled to a maximumof $9.0 million and a minimum of $5.0 million in earnout payments based on the level of customer count attained, as defined by theProvider Companies membership interest purchase agreement. In determining the fair value of the Provider Earnout, the Companyforecasted an expected customer count and certain other related criteria and calculated the probability of such forecast being attained.The Verde Earnout was based on achievement by the Verde Companies of certain performance targets over an 18 month periodfollowing the closing of the acquisition of the Verde Companies. In determining the fair value of the Verde Earnout, the Companyforecasted certain expected performance targets and calculated the probability of such forecast being attained. 107 Table of Contents12. Stock-Based CompensationRestricted Stock UnitsWe maintain a Long-Term Incentive Plan ("LTIP") for employees, consultants and directors of the Company and its affiliates whoperform services for the Company. The purpose of the LTIP is to provide a means to attract and retain individuals to serve as directors,employees and consultants who provide services to the Company by affording such individuals a means to acquire and maintainownership of awards, the value of which is tied to the performance of the Company’s Class A common stock. The LTIP provides forgrants of cash payments, stock options, stock appreciation rights, restricted stock or units, bonus stock, dividend equivalents, and otherstock-based awards with the total number of shares of stock available for issuance under the LTIP not to exceed 2,750,000 shares.Restricted stock units granted to our officers, employees, non-employee directors and certain employees of our affiliates who performservices for the Company vest over approximately one year for non-employee directors and ratably over approximately one to fouryears for officers, employees, and employees of affiliates, with the initial vesting date occurring in May of the subsequent year. Eachrestricted stock unit is entitled to receive a dividend equivalent when dividends are declared and distributed to shareholders of Class Acommon stock. These dividend equivalents are retained by the Company, reinvested in additional restricted stock units effective as ofthe record date of such dividends and vested upon the same schedule as the underlying restricted stock unit.The Company measures the cost of awards classified as equity awards based on the grant date fair value of the award, and theCompany measures the cost of awards classified as liability awards at the fair value of the award at each reporting period. TheCompany has utilized an estimated 6% annual forfeiture rate of restricted stock units in determining the fair value for all awardsexcluding those issued to executive level recipients and non-employee directors, for which no forfeitures are estimated to occur. TheCompany has elected to recognize related compensation expense on a straight-line basis over the associated vesting periods.Although the restricted stock units allow for cash settlement of the awards at the sole discretion of management of the Company,management intends to settle the awards by issuing shares of the Company’s Class A common stock.Total stock-based compensation expense for the years ended December 31, 2018, 2017 and 2016 was $5.9 million, $5.1 million and$5.2 million. Total income tax benefit related to stock-based compensation recognized in net (loss) income was $0.6 million, $0.8million and $0.8 million for the years ended December 31, 2018, 2017 and 2016.Equity Classified Restricted Stock UnitsRestricted stock units issued to employees and officers of the Company are classified as equity awards. The fair value of the equityclassified restricted stock units is based on the Company’s Class A common stock price as of the grant date. The Company recognizedstock based compensation expense of $5.3 million, $2.8 million and $2.3 million for the years ended December 31, 2018, 2017 and2016, respectively, in general and administrative expense with a corresponding increase to additional paid in capital.

As of December 31, 2018, there was $6.2 million of total unrecognized compensation cost related to the Company’sequity classified restricted stock units, which is expected to be recognized over a weighted average period of approximately 2.2 years.Change in Control Restricted Stock UnitsIn 2018, the Company granted Change in Control Restricted Stock Units ("CIC RSUs") to certain officers that vest upon a "Change inControl", if certain conditions are met. The terms of the CIC RSUs define a "Change in Control" to generally mean:–the consummation of an agreement to acquire or tender offer for beneficial ownership by any person, of 50% or more of thecombined voting power of our outstanding voting securities entitled to vote generally in the election of directors, or by anyperson of 90% or more of the then total outstanding shares of Class A common stock;–individuals who constitute the incumbent board cease for any reason to constitute at least a majority of the board;–consummation of certain reorganizations, mergers or consolidations or a sale or other disposition of all or substantially all of ourassets;–approval by our stockholders of a complete liquidation or dissolution;–a public offering or series of public offerings by Retailco and its affiliates, as a selling shareholder group, in which their totalinterest drops below 10 million of our total outstanding voting securities;–a disposition by Retailco and its affiliates in which their total interest drops below 10 million of our total outstanding votingsecurities; or–any other business combination, liquidation event of Retailco and its affiliates or restructuring of us which the CompensationCommittee deems in its discretion to achieve the principles of a Change in Control.The equity classified restricted stock unit table above excludes unvested CIC RSUs as the conditions for Change in Control have notbeen met. The Company has not recognized stock compensation expense related to the CIC RSUs as the Change in Control conditionshave not been met.Liability Classified Restricted Stock UnitsRestricted stock units issued to non-employee directors of the Company and employees of certain of our affiliates are classified asliability awards as the awards are either to a) non-employee directors that allow for the recipient to choose net settlement for the amountof withholding taxes dues upon vesting or b) to employees of certain affiliates of the Company and are therefore not deemed to beemployees of the Company. The fair value of the liability classified restricted stock units is based on the Company’s Class A commonstock price as of the reported period ending date. The Company recognized stock based compensation expense of $0.6 million, $2.3million and $3.0 million for years ended December 31, 2018, 2017 and 2016, respectively, in general and administrative expense with acorresponding increase to liabilities. As of December 31, 2018, the Company’s liabilities related to these restricted stock units recordedin current liabilities was $0.2 million. As of December 31, 2017, the Company's liabilities related to these restricted stock units recordedin current liabilities was $0.7 million.

Income TaxesWe and our subsidiaries, CenStar and Verde Energy USA, Inc. ("Verde Corp") are each subject to U.S. federal income tax ascorporations. CenStar and Verde Corp file consolidated tax returns in jurisdictions that allow combined reporting. Spark HoldCo and itssubsidiaries, 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 taxableincome is passed through to their members or partners. Accordingly, we are subject to U.S. federal income taxation on our allocableshare 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 ourownership in Spark HoldCo and for the income taxes attributable to CenStar and Verde Corp. Net income attributable to non-controllinginterest includes the provision for income taxes related to CenStar and Verde Corp.We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for future taxconsequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and the taxbases 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 inwhich those differences are expected to be recovered or settled in calculating the deferred tax assets and liabilities. Effects of changes intax rates on deferred tax assets and liabilities are recognized in income in the period of the tax rate enactment. A valuation allowance isrecorded 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 2017, the President signed the U.S. Tax Reform legislation, which enacted a wide range of changes to the U.S. Corporateincome tax system. Accordingly, we adjusted the value of our U.S. deferred tax assets and liabilities based on the rates at which theyare expected to be recognized in the future. For U.S. federal purposes the corporate statutory income tax rate was reduced from 35% to21%, effective for the 2018 tax year. During 2018, we completed our analysis of the impact of U.S. Tax Reform based on furtherguidance provided on the new tax law by the U.S. Treasury Department and Internal Revenue Service, with no material changes fromour assessment performed as of December 31, 2017.The provision for income taxes included the following components:110 Table of Contents(in thousands) 2018 2017 2016Current: Federal $3,862 $6,992 $5,361State 1,099 1,952 1,683Total Current 4,961 8,944 7,044 Deferred: Federal (2,792) 27,820 2,944State (92) 2,001 438 Total Deferred (2,884) 29,821 3,382Provision for income taxes $2,077 $38,765 $10,426 The effective income tax rate was (17)% and 34% for the years ended December 31, 2018 and 2017, respectively. The following tablereconciles the income tax benefit that would result from application of the statutory federal tax rate, 21% and 35% for the years endedDecember 31, 2018 and 2017, respectively, to the amount included in the consolidated statement of operations:(in thousands)20182017Expected provision at federal statutory rate$(2,586)$39,833Increase (decrease) resulting from: Non-controlling interest1,738(19,810)Class A Preferred Stock dividends1,5791,758Impact of U.S. Tax Reform—14,454Intra-entity transfer of customer contracts473—State income taxes, net of federal income tax effect4282,569Non-deductible expenses256234Other189(273)Provision for income taxes$2,077$38,765Total 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 bookand taxable income, most notably the income attributable to non-controlling interest, which gets taxed at the non-controlling interestpartner level. The effective rate in 2017 was also impacted by the enactment of U.S. Tax Reform. Since we were in a net deferred taxasset position, the rate reduced our overall asset having an unfavorable effect on tax expense.The components of our deferred tax assets as of December 31, 2018 and 2017 are as follows:111 Table of Contents(in thousands)20182017Deferred Tax Assets: Investment in Spark HoldCo$22,251$16,132Benefit of TRA Liability7,0168,175Federal net operating loss carryforward—660State net operating loss carryforward—166Other78—Total deferred tax assets29,34525,133 Deferred Tax Liabilities: Derivative liabilities(715)(811)Intangibles(849)(2,287)Property and equipment(460)—Other—(58) Total deferred tax liabilities(2,024)(3,156)Total deferred tax assets/liabilities$27,321$21,977The benefit of the TRA Liability relates to the step up in tax basis resulting from the purchase by the Company of Spark HoldCo unitsfrom our Founder at the time of our IPO. Subsequent issuances of Series A common stock, exchanges of Series A Common Stock forSeries B Shares and vesting of incentive stock compensation since our IPO has also resulted in step ups in the basis of our stocksimilarly resulting in a liability under our Tax Receivable Agreement. As of December 31, 2018 and 2017, we have a current liability of$1.7 million and $5.9 million and a long-term liability of $25.9 million and $26.4 million to record the overall effect of the TaxReceivable Agreement. See Note 15 "Transactions with Affiliates" for further discussion.We periodically assess whether it is more likely than not that we will generate sufficient taxable income to realize our deferred incometax assets. In making this determination, we consider all available positive and negative evidence and makes certain assumptions. Weconsider, among other things, our deferred tax liabilities, the overall business environment, our historical earnings and losses, currentindustry trends, and our outlook for future years. We believe it is more likely than not that our deferred tax assets will be utilized, andaccordingly have not recorded a valuation allowance on these assets.The tax years 2013 through 2017 remain open to examination by the major taxing jurisdictions to which the Company is subject toincome tax. An affiliate owned by our Founder would be responsible for any audit adjustments incurred in connection with transactionsoccurring prior to July 2014 for Spark Energy, Inc. and Spark HoldCo.Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement methodology for the financialstatement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of December 31, 2018 and2017 there was no liability, and for the years ended December 31, 2018, 2017 and 2016, there was no expense recorded for interestand penalties associated with uncertain tax positions or unrecognized tax positions. Additionally, the Company does not haveunrecognized tax benefits as of December 31, 2018 and 2017.14. Commitment and ContingenciesFrom time to time, we may be involved in legal, tax, regulatory and other proceedings in the ordinary course of business. Liabilities forloss contingencies arising from claims, assessments, litigation or other sources are recorded when it is probable that a liability has beenincurred and the amount can be reasonably estimated.Legal Proceedings112 Table of ContentsWe are subject to lawsuits and claims arising in the ordinary course of our business. This litigation is in various stages, and the mattersdiscussed below are subject to substantial uncertainties concerning the outcome of material factual and legal issues. Accordingly, wecannot currently predict the manner and timing of the resolution of this litigation or estimate a range of possible losses or a minimumloss that could result from an adverse verdict in a potential lawsuit. While the lawsuits and claims are asserted for amounts that may bematerial should an unfavorable outcome occur, management does not currently expect that any currently pending matters will have amaterial adverse effect on our financial position or results of operations.Katherine Veilleux, et. al. v. Electricity Maine LLC, Provider Power, LLC, Spark HoldCo, LLC, Kevin Dean, and Emile Clavet is apurported class action lawsuit filed on November 18, 2016 in the United States District Court of Maine, alleging that Electricity Maine,LLC (Electricity Maine), an entity acquired by Spark Holdco, LLC (Spark Holdco) in mid-2016, enrolled and re-enrolled customersthrough fraudulent and misleading advertising, promotions, and other communications prior to and following the acquisition. Plaintiffsallege claims under RICO, the Maine Unfair Trade Practice Act, civil conspiracy, fraudulent misrepresentation, unjust enrichment andbreach of contract. Plaintiffs seek damages for themselves and the purported class, rescission of contracts with Electricity Maine,injunctive relief, restitution, and attorney’s fees. Discovery is ongoing in this matter. Spark HoldCo and Electricity Maine intend tovigorously defend this matter and the allegations asserted therein, including the request to certify a class. Electricity Maine and SparkHoldCo intend to file a motion to compel arbitration of certain Plaintiffs’ claims as the applicable Terms of Service in this case containan arbitration provision and class action waiver. The Company believes it has full indemnity coverage for any actual exposure in thiscase at this time.Gillis et al. v. Respond Power, LLC is a purported class action lawsuit that was originally filed on May 21, 2014 in the PhiladelphiaCourt of Common Pleas but was later removed to the United States District Court for the Eastern District of Pennsylvania. On September15, 2014, the plaintiffs filed an amended class action complaint seeking a declaratory judgment that the disclosure statement containedin Respond Power, LLC’s variable rate contracts with Pennsylvania consumers limited the variable rate that could be charged to nomore than the monthly rate charged by the consumers’ local utility company and alleged claims of deceptive conduct in violation ofPennsylvania Unfair Trade Practices and Consumer Protection Act, negligent misrepresentation, fraudulent concealment, and breach ofcontract and of the covenant of good faith and fair dealing by charging rates above the utility. The amount of damages sought is notspecified. By order dated August 31, 2015, the district court denied class certification. The plaintiffs appealed the district court’s denialof class certification to the United States Court of Appeals for the Third Circuit and that court vacated the district court’s denial of classcertification and remanded the matter to the district court for further proceedings. On July 16, 2018, the district court granted RespondPower LLC's motion to dismiss the Plaintiff’s class action claims. Plaintiffs filed their notice of appeal to the Third Circuit Court onAugust 7, 2018. The Third Circuit has not yet ruled or set any hearings on this appeal.

On September 24, 2018, the court granted our motion to dismiss in part and dismissed theplaintiffs’ fraudulent inducement claims but allowed the tortious interference claims to remain as well as the claims for consequentialdamages and punitive damages. NG&E and the Company filed their affirmative defenses and answer to the remaining claims onOctober 15, 2018. Discovery has commenced and written discovery requests have been exchanged between the parties. This case iscurrently set for trial on September 9, 2019. The Company and NG&E deny the allegations asserted and intend to vigorously defendthis matter. Given the early stages of this matter, we cannot predict the outcome or consequences of this case at this time. Regulatory MattersOn 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 mailadvertisements to sign up for electricity services. The complaint seeks injunctive relief and monetary damages representing the amountsIllinois consumers have allegedly lost due to fraudulent marketing activities. The Attorney General also requests civil penalties underthe Consumer Fraud Act and to revoke Major’s authority to operate in the state. The complaint was filed in the Circuit Court of CookCounty, 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 rulingwith a Motion for Entry of a Certified Question. Appellate briefs are due in February 2019 and discovery has begun. Major denies theallegations asserted and intends to vigorously defend this matter, however, we cannot predict the outcome or consequences of this caseat 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 $0.9million primarily for Spark's alleged failure to comply with requirements implemented in 2016 that customer bills include any changesto existing rates effective for the next billing cycle. After a hearing process was concluded and Spark Energy, LLC filed a briefchallenging the legal authority of PURA to enforce the NOV and impose civil penalties for the alleged violations, PURA suspended theproceeding and opened a proceeding offering amnesty to ESCOs that self-report violations and offer to voluntarily remit refunds tocustomers. Spark has announced its intention to participate in the amnesty proceeding. The second investigation involves a NOValleging improper marketing practices of one of Spark Energy, LLC's former outbound telemarketing vendors and assessment of aproposed civil penalty of $0.8 million. Certain agents managed by this vendor were allegedly using an unauthorized script in outboundmarketing 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 becomecommon and are often resolved in a manner that allows the retailer to continue operating in Connecticut, there can be no assurance thatPURA will not take more severe action.114 Table of ContentsIndirect Tax AuditsWe are undergoing various types of indirect tax audits spanning from years 2013 to 2018 for which we may have additional liabilitiesarise. At the time of filing these consolidated financial statements, these indirect tax audits are at an early stage and subject to substantialuncertainties concerning the outcome of audit findings and corresponding responses.As of December 31, 2018, we have accrued $0.9 million related to litigation and regulatory matters and $0.6 million related to indirecttax audits. The outcome of each of these may result in additional expense.15. Transactions with AffiliatesTransactions with AffiliatesWe enter into transactions with and pay certain costs on behalf of affiliates that are commonly controlled in order to reduce risk, reduceadministrative expense, create economies of scale, create strategic alliances and supply goods and services to these related parties. Wealso sell and purchase natural gas and electricity with affiliates. We present receivables and payables with the same affiliate on a netbasis in the condensed consolidated balance sheets as all affiliate activity is with parties under common control. Affiliated transactionsinclude certain services to the affiliated companies associated with employee benefits provided through our benefit plans, insuranceplans, leased office space, administrative salaries, due diligence work, recurring management consulting, and accounting, tax, legal, ortechnology services. Amounts billed are based on the services provided, departmental usage, or headcount, which are consideredreasonable by management.

These amounts are presented as neton the Consolidated Statements of Operations.Acquisitions from AffiliatesIn 2017, we acquired Perigee from our affiliate, NG&E, for total consideration of approximately $4.1 million.In connection with the Major Energy Companies acquisition, we issued 4,000,000 shares of Class B common stock (and acorresponding number of Spark HoldCo units) to NG&E, valued at $40.0 million. In connection with the financing of the ProviderCompanies acquisition, we issued 1,399,484 shares of Class B common stock (and a corresponding number of Spark HoldCo units) toRetailCo, valued at $14.0 million.In March 2018, we entered into an asset purchase agreement with NG&E to acquire up to 50,000 RCEs from NG&E for a cashpurchase price of $250 for each RCE, or up to $12.5 million in the aggregate. A total of $8.8 million was paid in 2018 under the termsof the purchase agreement for approximately 35,000 RCEs, and no further material payments are anticipated. The acquisition wastreated as a transfer of assets between entities under common control, and accordingly, the assets were recorded at their historical valueat the date of transfer. The transaction resulted in $7.1 million recorded in equity as a net distribution to affiliate as of December 31,2018.Distributions to and Contributions from AffiliatesDuring the years ended December 31, 2018, 2017 and 2016, we made distributions to affiliates of our Founder of $15.5 million, $15.6million and $23.7 million, respectively, for payments of quarterly distributions on their respective Spark HoldCo units.

The subordinated note allows us to draw advances in increments of no less than $1.0 millionper advance up to the maximum principal amount of the subordinated note. Advances thereunder accrue interest at 5% per annum fromthe date of the advance. As of December 31, 2018 and 2017, there was $10.0 million and zero, respectively, outstanding under thesubordinated note. See Note 10 "Debt" for a further description of terms and conditions of the facility.Tax Receivable AgreementWe maintain a Tax Receivable Agreement with affiliates that generally provides for the payment by us to affiliates of 85% of the netcash savings, if any, in U.S. federal, state and local income tax or franchise tax that we realize or will realize (or are deemed to realize incertain circumstances) in future periods as a result of (i) any tax basis increases resulting from the initial purchase by us of SparkHoldCo units from entities owned by our Founder, (ii) any tax basis increases resulting from the exchange of Spark HoldCo units forshares of Class A common stock pursuant to the Exchange Right (or resulting from an exchange of Spark HoldCo units for cashpursuant to the 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. We retain the benefit of the remaining 15% of these tax savings. SeeNote 13 "Income Taxes" for further discussion.In certain circumstances, we may defer or partially defer any payment due (a “TRA Payment”) to the holders of rights under the TaxReceivable Agreement for a five-year period that ends September 30, 2019. Deferral of payment is required to the extent that SparkHoldCo does not generate sufficient Cash Available for Distribution (as defined below) during the four-quarter period endingSeptember 30th of the applicable year in which the TRA Payment is to be made in an amount that equals or exceeds 130% (the “TRACoverage Ratio”) of the Total Distributions (as defined below) paid in such four-quarter period by Spark HoldCo. For purposes ofcomputing the TRA Coverage Ratio: •“Cash Available for Distribution” is generally defined as the Adjusted EBITDA of Spark HoldCo for the applicable period, less(i) cash interest paid by Spark HoldCo, (ii) capital expenditures of Spark HoldCo (exclusive of customer acquisition costs) and(iii) any taxes payable by Spark HoldCo; and•“Total Distributions” are defined as the aggregate distributions necessary to cause us to receive distributions of cash equal to (i)the targeted quarterly distribution we intend to pay to holders of our Class A common and Series A Preferred Stock payableduring the applicable four-quarter period, plus (ii) the estimated taxes payable by us during such four-quarter period, plus (iii)the expected TRA Payment payable during the calendar year for which the TRA Coverage Ratio is being tested.At the end of the deferral period, we are obligated to pay any outstanding deferred TRA Payments to the extent such deferred TRAPayments do not exceed (i) the lesser of our proportionate share of aggregate Cash Available for Distribution of Spark HoldCo duringthe five-year deferral period or the cash distributions actually received by us during the five-year deferral period, reduced by (ii) thesum of (a) the aggregate target quarterly dividends (which, for the purposes of the Tax Receivable Agreement, will be $0.18125 perClass A common stock share and $0.546875 per Series A Preferred Stock share per quarter) during the five-year deferral period, (b) ourestimated taxes during the five-year deferral period, (c) all prior TRA Payments and (d) if with respect to the quarterly period duringwhich the deferred TRA Payment is otherwise paid or payable, Spark HoldCo has or reasonably determines it will have amountsnecessary to cause us to receive distributions of cash equal to the target quarterly distribution payable during that quarterly period. Anyportion of the deferred TRA Payments not payable due to these limitations will no longer be payable.For the four-quarter periods ending September 30, 2016, 2017, and 2018, we met the threshold coverage ratio required to fund thepayments required under the Tax Receivable Agreement. Our affiliates, however, granted us the right to defer the TRA payment relatedto the four-quarter period ending September 30, 2016 until May 2018. In April, May, and December of 2018, we paid a total of $6.2million related to our obligations under the TRA for the 2015, 2016, and 2017 tax years.117 Table of ContentsAs of December 31, 2018 and 2017, we had a total liability related to the TRA of $27.6 million and $32.3 million, of which $1.7million and $5.9 million, respectively, were classified as current liabilities.16. Segment ReportingOur determination of reportable business segments considers the strategic operating units under which we make financial decisions,allocate resources and assess performance of our business. Our 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 naturalgas segment consists of natural gas sales to, and natural gas transportation and distribution for, 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 aconsolidated 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 $113.7 million, $178.3 millionand $133.0 million and asset optimization cost of revenues of $109.2 million, $179.0 million and $133.6 million, respectively, whichare presented on a net basis in asset optimization revenues.We use retail gross margin to assess the performance of our operating segments. Retail gross margin is defined as operating income(loss) plus (i) depreciation and amortization expenses and (ii) general and administrative expenses, less (i) net asset optimizationrevenues (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 cashsettlements, from the retail gross margin calculation in order to remove the non-cash impact of net gains and losses on these derivativeinstruments. Retail gross margin should not be considered an alternative to, or more meaningful than, operating income, as determinedin accordance with GAAP.Below is a reconciliation of retail gross margin to (loss) income before income tax expense (in thousands): Years Ended December 31,(in thousands) 2018 2017 2016Reconciliation of Retail Gross Margin to Income before taxes (Loss) income before income tax expense $(12,315) $113,809 $76,099Change in Tax Receivable Agreement Liability — (22,267) —Interest and other income (749) (256) (957)Interest expense 9,410 11,134 8,859Operating (loss) income (3,654) 102,420 84,001Depreciation and amortization 52,658 42,341 32,788General and administrative 111,431 101,127 84,964Less: Net asset optimization revenue (expenses) 4,511 (717) (586)Net, (losses) gain on non-trading derivative instruments (19,571) 5,588 22,254Net, Cash settlements on non-trading derivative instruments (9,614) 16,508 (2,284)Retail Gross Margin $185,109 $224,509 $182,369Financial data for business segments are as follows (in thousands):118 Table of ContentsYear Ended December 31,2018RetailElectricity RetailNatural Gas Corporateand Other Eliminations ConsolidatedTotal Revenues$863,451 $137,966 $4,511 $— $1,005,928Retail cost of revenues762,771 82,722 — — 845,493Less: Net asset optimization revenue— — 4,511 — 4,511Net, Losses on non-trading derivativeinstruments(15,200) (4,371) — — (19,571)Current period settlements on non-tradingderivatives(8,788) (826) — — (9,614)Retail gross margin$124,668 $60,441 $— $— $185,109Total Assets $1,857,790 $649,969 $361,697 $(2,380,718) $488,738Goodwill$117,813 $2,530 $120,343Year Ended December 31,2017RetailElectricityRetailNatural GasCorporateand OtherEliminationsConsolidatedTotal Revenues (1)$657,566$141,206$(717)$—$798,055Retail cost of revenues477,01275,155——552,167Less:Net asset optimization expense (1)——(717)—(717)Net, Gains (losses) on non-trading derivativeinstruments5,784(196)——5,588Current period settlements on non-tradingderivatives16,302206——16,508Retail gross margin$158,468$66,041$—$—$224,509Total Assets (2)$1,218,243$421,896$281,176$(1,417,574)$503,741Goodwill$117,624 $2,530 $— $— $120,154Year Ended December 31,2016RetailElectricityRetailNatural GasCorporateand OtherEliminationsConsolidatedTotal Revenues (1)$417,229$130,054$(586)$—$546,697Retail cost of revenues286,79558,149——344,944Less:Net asset optimization expense (1)——(586)—(586)Net, Gains on non-trading derivativeinstruments17,1875,067——22,254Current period settlements on non-tradingderivatives(4,889)2,605——(2,284)Retail gross margin$118,136$64,233$—$—$182,369Total Assets (2)$551,338 $242,739 $192,101 $(618,429) $367,749Goodwill$76,617$2,530$—$—$79,147(1) Previously reported amounts have been adjusted to reclassify net asset optimization actives from the Retail Natural Gas segment to Corporate and Other.(2) Previously reported amounts have been adjusted for immaterial corrections.

Changes in and Disagreements with Accountants on Accounting and Financial DisclosureNone.Item 9A. Controls and ProceduresEvaluation of Disclosure Controls and ProceduresOur management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectivenessof 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 otherprocedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it filesor submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’srules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure thatinformation required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated andcommunicated to the company’s management, including its principal executive and principal financial officers or persons performingsimilar functions, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls andprocedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, andmanagement necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Based onthis evaluation, management concluded that our disclosure controls and procedures were effective as of December 31, 2018 at thereasonable assurance level.Management's Annual Report on Internal Control Over Financial ReportingSee "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 FirmThis Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm on ourinternal control over financial reporting because Section 103 of the JOBS Act provides that an emerging growth company is notrequired to provide an auditor's report on internal control over financial reporting for as long as we qualify as an emerging growthcompany.Changes in Internal Control over Financial ReportingThere 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.
