SPARK ENERGY, INC.

NOTES TO CONDENSED COMBINED AND CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Formation and Organization

Organization

Spark Energy, Inc. ("we" or the “Company”) is an independent retail energy services company that provides residential and commercial customers in competitive markets across the United States with an alternative choice for natural gas and electricity. The Company is a holding company whose sole material asset consists of units in Spark HoldCo, LLC (“Spark HoldCo”). Spark HoldCo owns all of the outstanding membership interests or shares in each of Spark Energy, LLC (“SE”), Spark Energy Gas, LLC (“SEG”), Oasis Power Holdings, LLC ("Oasis") and CenStar Energy Corp. ("CenStar"), the operating subsidiaries through which the Company operates. The Company is the sole managing member of Spark HoldCo, is responsible for all operational, management and administrative decisions relating to Spark HoldCo’s business and consolidates the financial results of Spark HoldCo and its subsidiaries.

The Company is a Delaware corporation formed on April 22, 2014 by Spark Energy Ventures, LLC (“Spark Energy Ventures”) for the purpose of succeeding to Spark Energy Ventures’ ownership in SE and SEG. Spark Energy Ventures, a single member limited liability company formed on October 8, 2007 under the Texas Limited Liability Company Act (“TLLCA”) is an affiliate of NuDevco Retail Holdings, LLC (“NuDevco Retail Holdings”), a single member Texas limited liability company formed by Spark Energy Ventures on May 19, 2014 under the Texas Business Organizations Code (“TBOC”). NuDevco Retail Holdings was formed by Spark Energy Ventures to hold its investment in Spark HoldCo, LLC, our subsidiary and the direct parent of SEG and SE. NuDevco Retail Holdings is currently a direct wholly owned subsidiary of Electric Holdco, LLC, which is indirectly wholly owned by W. Keith Maxwell III. NuDevco Retail Holdings formed NuDevco Retail, LLC (“NuDevco Retail” and, together with NuDevco Retail Holdings, “NuDevco”), a single member limited liability company, on May 29, 2014 and it holds a 1% interest in Spark HoldCo formerly held by NuDevco Retail Holdings.

Prior to the closing of the Company’s initial public offering of 3,000,000 shares of Class A common stock, par value $0.01 per share (the “Class A common stock”), representing a 21.82% interest in the Company, on August 1, 2014 (the “Offering”) Spark Energy Ventures contributed all of its interest in each of SE and SEG to NuDevco Retail Holdings. NuDevco Retail Holdings in turn contributed all of its interest in each of SE and SEG to Spark HoldCo. The contribution of the interests in SE and SEG to Spark HoldCo is not considered a business combination accounted for under the purchase method, as it was a transfer of assets and operations under common control, and accordingly, balances were transferred at their historical cost. The Company’s historical condensed combined financial statements prior to the Offering are prepared using SE’s and SEG’s historical basis in the assets and liabilities, and include all revenues, costs, assets and liabilities attributed to the retail natural gas and asset optimization and retail electricity businesses of SE and SEG.

SE is a licensed retail electric provider in multiple states. SE provides retail electricity services to end-use retail customers, ranging from residential and small commercial customers to large commercial and industrial users. SE was formed on February 5, 2002 under the Texas Revised Limited Partnership Act (as recodified by the TBOC) and was converted to a Texas limited liability company on May 21, 2014.

SEG is a retail natural gas provider and asset optimization business competitively serving residential, commercial and industrial customers in multiple states. SEG was formed on January 17, 2001 under the Texas Revised Limited Partnership Act (as recodified by the TBOC) and was converted to a Texas limited liability company on May 21, 2014.

Oasis, through its operating subsidiary, Oasis Power LLC, is a retail energy provider with approximately 43,000 customers in six states as of September 30, 2015. Oasis was formed on August 28, 2009 as a limited liability company under the TBOC. We acquired Oasis on July 31, 2015 from an affiliate. Financial information has been

recast to include results attributable to the acquisition of Oasis on May 12, 2015, the affiliate's acquisition date. See Note 2 “Basis of Presentation” and Note 3 "Acquisitions" for further discussion.

CenStar is a retail energy provider with approximately 16,000 customers in three states as of September 30, 2015. CenStar was incorporated on July 18, 2008 under the New York Business Corporation Law. We acquired CenStar on July 8, 2015.

As a company with less than $1.0 billion in revenues during its last fiscal year, the Company qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other regulatory requirements.

The Company will remain an “emerging growth company” for up to five years, or until the earliest of (i) the last day of the fiscal year in which the Company has $1.0 billion or more in annual revenues; (ii) the date on which the Company becomes a “large accelerated filer” (the fiscal year-end on which the total market value of the Company’s common equity securities held by non-affiliates is $700 million or more as of June 30); (iii) the date on which the Company issues more than $1.0 billion of non-convertible debt over a three-year period; or (iv) the last day of the fiscal year following the fifth anniversary of the Offering.

As a result of the Company's election to avail itself of certain provisions of the JOBS Act, the information that the Company provides may be different than what you may receive from other public companies in which you hold an equity interest.

Initial Public Offering of Spark Energy, Inc.

On August 1, 2014, the Company completed the Offering of 3,000,000 shares of its Class A common stock for $18.00 per share, representing an approximate 21.82% voting interest in the Company.

Net proceeds from the Offering were $47.6 million , after underwriting discounts and commissions, structuring fees and offering expenses. The net proceeds from the Offering were used to acquire units of Spark HoldCo (the “Spark HoldCo units”) representing approximately 21.82% of the outstanding Spark HoldCo units after the Offering from NuDevco Retail Holdings and to repay a promissory note from the Company in the principal amount of $50,000 (the “NuDevco Note”). The Company did not retain any of the net proceeds from the Offering. The Company recorded $2.7 million of previously deferred incremental costs directly attributable to the Offering as a reduction in equity at the Offering date, which were funded by the Offering proceeds.

The Company also issued 10,750,000 shares of Class B common stock, par value $0.01 per share (the “Class B common stock”) to Spark HoldCo, 10,612,500 of which Spark HoldCo distributed to NuDevco Retail Holdings, and 137,500 of which Spark HoldCo distributed to NuDevco Retail.

Each share of Class B common stock, all of which is held by NuDevco, has no economic rights but entitles its holder to one vote on all matters to be voted on by shareholders generally. Holders of Class A common stock and Class B common stock vote together as a single class on all matters presented to our shareholders for their vote or approval, except as otherwise required by applicable law or by our certificate of incorporation.

The Spark HoldCo Limited Liability Company Agreement provides that anytime the Company issues a new share of Class A or Class B common stock (except for issuances of Class A common stock upon an exchange of Class B common stock), Spark HoldCo will concurrently issue a 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.  As a result, the number of Spark HoldCo units held by the Company always equals the number of shares of Class A common stock outstanding.

At the consummation of the Offering, the Company's outstanding common stock is summarized in the table below:

Exchange and Registration Rights

NuDevco has the right to exchange (the “Exchange Right”) all or a portion of its Spark HoldCo units (together with a corresponding number of shares of Class B common stock) for Class A common stock (or cash at Spark Energy, Inc.’s or Spark HoldCo’s election (the “Cash Option”) at an exchange ratio of one share of Class A common stock for each Spark HoldCo unit (and corresponding share of Class B common stock) exchanged. In addition, NuDevco has the right, under certain circumstances, to cause the Company to register the offer and resale of NuDevco's shares of Class A common stock obtained pursuant to the Exchange Right.

2. Basis of Presentation

The accompanying interim unaudited condensed combined and consolidated financial statements (“interim statements”) of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC"), and include all wholly owned subsidiaries. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. Refer to further discussion at Note 15 "Equity Method Investment".

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the interim financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Effects on the business, financial condition and results of operations resulting from revisions to estimates are recognized when the facts that give rise to the revision become known. The information furnished herein reflects all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the condensed combined and consolidated financial statements. Operating results for the nine months ended September 30, 2015  are not necessarily indicative of the results which may be expected for the full year or for any interim period. 

The accompanying interim unaudited condensed combined and consolidated financial statements have been prepared in accordance with Regulation S-X, Article 3, General Instructions as to Financial Statements and Staff Accounting Bulletin (“SAB”) Topic 1-B, Allocations of Expenses and Related Disclosures in Financial Statements of Subsidiaries, Divisions or Lesser Business Components of Another Entity on a stand-alone basis and are derived from SE’s and SEG’s historical basis in the assets and liabilities before the Offering and Spark Energy Inc.'s financial results after the Offering, and include all revenues, costs, assets and liabilities attributable to the retail natural gas and asset optimization and retail electricity businesses of SE and SEG for the periods prior to the Offering that are specifically identifiable or have been allocated to the Company. Management has made certain assumptions and estimates in order to allocate a reasonable share of expenses to the Company, such that the Company’s consolidated financial statements reflect substantially all of its costs of doing business.

Transactions with Affiliates

The Company also enters into transactions with and incurs certain costs on behalf of affiliates that are commonly controlled by W. Keith Maxwell III in order to reduce risk, reduce administrative expense, create economies of

scale, create strategic alliances and supply goods and services to these related parties. These transactions include, but are not limited to, certain services to the affiliated companies associated with the Company’s debt facility prior to the Offering, employee benefits provided through the Company’s benefit plans, insurance plans, leased office space, and administrative salaries for management due diligence work, recurring management consulting, accounting, tax, legal, or technology services based on services provided, departmental usage, or headcount, which are considered reasonable by management. As such, the accompanying condensed combined and consolidated financial statements include costs that have been incurred by the Company and then directly billed or allocated to affiliates and are recorded net in general and administrative expense on the condensed combined and consolidated statements of operations with a corresponding accounts receivable—affiliates recorded in the condensed combined and consolidated balance sheets. Additionally, the Company enters into transactions with certain affiliates for sales or purchases of natural gas and electricity, which are recorded in retail revenues, retail cost of revenues, and net asset optimization revenues in the condensed combined and consolidated statements of operations with a corresponding accounts receivable—affiliate or accounts payable—affiliate in the condensed combined and consolidated balance sheets. The allocations and related estimates and assumptions are described more fully in Note 12 “Transactions with Affiliates.”

These costs are not necessarily indicative of the cost that the Company would have incurred had it operated as an independent stand-alone entity prior to the Offering. Affiliates have also relied upon Spark Energy Ventures as a participant in the credit facility for periods prior to the Offering as described more fully in Note 5 “Long-Term Debt.” As such, the Company’s interim unaudited condensed combined and consolidated financial statements do not fully reflect what the Company’s financial position, results of operations and cash flows would have been had the Company operated as an independent stand-alone company prior to the Offering. As a result, historical financial information prior to the Offering is not necessarily indicative of what the Company’s results of operations, financial position and cash flows will be in the future. The Company's unaudited condensed consolidated financial statements subsequent to the Offering are presented on a consolidated basis and include all wholly-owned and controlled subsidiaries.

Presentation of the Acquisition of Oasis Power Holdings, LLC

On May 12, 2015, Retailco Acquisition Co, LLC ("Retailco"), an affiliate of NuDevco, completed the acquisition of 100% of the membership interests of Oasis. Also, on May 12, 2015, Spark HoldCo entered into a Membership Interest Purchase Agreement (the "Oasis Purchase Agreement") with Retailco for the purchase of all the membership interests of Oasis. Spark HoldCo completed the acquisition of Oasis from Retailco on July 31, 2015. See Note 3 "Acquisitions" for further discussion. Because the acquisition of Oasis was a transfer of equity interests of entities under common control, the Company's historical financial statements previously filed with the SEC have been recast in this Form 10-Q to include the results attributable to Oasis from May 12, 2015. The unaudited condensed consolidated financial statements for this recast period have been prepared from Retailco's historical cost-basis and may not necessarily be indicative of the actual results of operations that would have occurred had the Company owned Oasis during the recast period.

Subsequent Events

Subsequent events have been evaluated through the date these financial statements are issued. Any material subsequent events that occurred prior to such date have been properly recognized or disclosed in the condensed combined and consolidated financial statements. See Note 16 “Subsequent Events” for further discussion.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB") issued Accounting Standards Update (“ASU”) No. 2014-09 ("ASU 2014-09"),  Revenue from Contracts with Customers (Topic 606) , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP. The standard permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU

No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which deferred the effective date to periods beginning after December 15, 2017. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810), Amendments to the Consolidation Analysis (“ASU 2015-02”). The new guidance changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. ASU 2015-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption at an interim period. The Company has not yet determined the effect of the standard on its ongoing financial reporting.

In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30) (“ASU 2015-03”). The new guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The Company will adopt ASU 2015-03 on January 1, 2016 and reclassify any unamortized debt issuance costs as a direct deduction from the carrying amount of those associated debt liabilities at that time.

In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”). ASU 2015-11 amends existing guidance to require subsequent measurement of inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU 2015-11 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016. Earlier application is permitted as of the beginning of an interim or annual reporting period. The Company does not expect the adoption of ASU 2015-11 will have a material effect on the combined or consolidated financial statements.

In August 2015, the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements ("ASU 2015-15"). The amendment in ASU 2015-15 clarifies the presentation and subsequent measurement of debt issuance costs associated with lines of credit. The debt issuance cost associated with line-of-credit may be presented as an asset and amortized ratably over the term of the line of credit arrangement, regardless of whether there are outstanding borrowings on the arrangement. ASU 2015-15 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The Company will adopt ASU 2015-15 on January 1, 2016 in conjunction with ASU 2015-03 and does not expect the adoption of ASU 2015-15 will have a material effect on the combined or consolidated financial statements.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments ("ASU 2015-16"). ASU 2015-16 eliminates the requirement that the acquirer in a business combination account for measurement period adjustments retrospectively. Instead, the acquirer will recognize adjustments to provisional amounts identified within the measurement period in the reporting period in which those adjustments are determined. ASU 2015-16 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The guidance is to be applied prospectively for adjustments to provisional amounts that occur after the effective date. Early adoption is permitted for financial statements that have not been issued. The Company will adopt ASU 2015-16 on January 1, 2016 and does not expect the adoption of ASU 2015-15 will have a material effect on the combined or consolidated financial statements.

3. Acquisitions

Acquisition of CenStar Energy Corp

On July 8, 2015, the Company completed its acquisition of CenStar, a retail energy company based in New York. CenStar serves natural gas and electricity customers in New York, New Jersey, and Ohio. The purchase price for the CenStar acquisition was $8.3 million , plus working capital of $10.4 million and an earnout payment estimated as of the acquisition date to be $0.5 million , which is associated with a financial measurement attributable to the operations of CenStar for the year following the closing ("CenStar Earnout"). See Note 6 "Fair Value Measurements" for further discussion on the CenStar Earnout. The purchase price was financed with $16.6 million (including positive working capital of $10.4 million ) under our senior secured revolving credit facility ("Senior Credit Facility") and $2.1 million from the issuance of a convertible subordinated note ("CenStar Note") from the Company and Spark HoldCo to Retailco. See Note 5 "Debt" for further discussion of the Senior Credit Facility and the CenStar Note.

The acquisition of CenStar has been accounted for under the acquisition method in accordance with ASC 805, Business Combinations (“ASC 805”) . The allocation of purchase consideration was based upon the estimated fair value of the tangible and identifiable intangible assets acquired and liabilities assumed in the acquisition. The allocation was made to major categories of assets and liabilities based on management’s best estimates, supported by independent third-party analyses. The excess of the purchase price over the estimated fair value of tangible and intangible assets acquired and liabilities assumed was allocated to goodwill. The allocation of the purchase consideration is as follows (in thousands):

The fair values of intangible assets were measured primarily based on significant inputs that are not observable in the market and thus represent a Level 3 measurement as defined by ASC 820, "Fair Value Measurement" ("ASC 820"). The fair value of derivative liabilities were measured by utilizing readily available quoted market 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 measurement as defined by ASC 820. Refer to Note 6 "Fair Value Measurements" for further discussion on the fair values hierarchy. Significant inputs for Level 3 measurements were as follows:

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

Trademark. The fair value of the CenStar trademark is reflective of the value associated with the recognition and positive reputation of CenStar to its target markets. This value would otherwise have to be internally developed through significant time and expense or by paying a third party for its use. The fair value of the trademark was

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

Goodwill. The excess of the purchase consideration over the estimated fair value of the amounts initially assigned to the identifiable assets acquired and liabilities assumed was recorded as goodwill. Goodwill arose on the acquisition of CenStar primarily due to its strong brand and broker affinity relationships, along with access to new utility service territories. Goodwill recorded in connection with the acquisition of CenStar is not deductible for income tax purposes because CenStar was an acquisition of all outstanding equity interests. The final valuation of assets acquired and liabilities assumed is not complete and the net adjustments to those values may result in changes to goodwill and other carrying amounts initially assigned to the assets and liabilities based on the preliminary fair value analysis. The principal remaining item relates to finalization of the valuation of customer relationships and working capital amounts, which are expected to be finalized once the period for post-closing adjustments expires in the fourth quarter of 2015.

The Company’s condensed consolidated statements of operations for the three and nine months ended September 30, 2015, respectively, included $10.4 million of revenue and $1.1 million of losses from operations related to the operations of CenStar. The Company incurred $0.1 million of customer acquisition costs for the three and nine months ended September 30, 2015, respectively, in connection with the acquisition of CenStar, which have been expensed as incurred and included in general and administrative expense in the condensed consolidated statement of operations.

Acquisition of Oasis Power Holdings, LLC

On July 31, 2015, the Company completed its acquisition of Oasis, a retail energy company operating in six states across 18 utilities. The purchase price for the Oasis acquisition was $20.0 million , subject to working capital adjustments. The purchase price was financed with $15.0 million in borrowings under our Senior Credit Facility and $5.0 million from the issuance of a convertible subordinated note ("Oasis Note") from the Company and Spark HoldCo to Retailco. See Note 5 "Debt" for further discussion of the Senior Credit Facility and the Oasis Note.

As discussed in Note 2 "Basis of Presentation," the acquisition of Oasis by the Company from Retailco was a transfer of equity interests of entities under common control on July 31, 2015. Accordingly, the assets acquired and liabilities assumed were based on their historical values as of July 31, 2015 as follows (in thousands):

Goodwill was transferred based on the acquisition of Oasis by Retailco on May 12, 2015 and was primarily due to Oasis's brand strength, established vendor relationships and access to new utility service territories. Goodwill recorded in connection with the transfer of Oasis is deductible for income tax purposes.

The Company’s condensed consolidated statements of operations for three months ended September 30, 2015 included $10.6 million of revenue and $0.5 million of income from operations related to the operations of Oasis.

The Company’s condensed consolidated statements of operations for nine months ended September 30, 2015 included $15.4 million of revenue and $0.1 million of loss from operations related to the operations of Oasis.

4. Property and Equipment

Property and equipment consist of the following amounts as of:

Information technology assets include software and consultant time used in the application, development and implementation of various systems including customer billing and resource management systems. As of September 30, 2015 and December 31, 2014 , information technology includes $0.7 million and $0.4 million , respectively, of costs associated with assets not yet placed into service.

Depreciation expense recorded in the condensed combined and consolidated statements of operations was $0.3 million and $0.8 million for the three months ended September 30, 2015 and 2014, respectively, and $1.2 million and $2.7 million for the nine months ended September 30, 2015 and 2014, respectively.

5. Debt

Prior to the Offering - Overview

In October 2007, Spark Energy Ventures and all of its subsidiaries (collectively, the “Borrowers”), entered into a credit agreement, consisting of a working capital facility, a term loan and a revolving credit facility (the “Credit Agreement”), with SE and SEG as co-borrowers under which they were jointly and severally liable for amounts Borrowers borrowed under the Credit Agreement. The Credit Agreement was secured by substantially all of the assets of Spark Energy Ventures and its subsidiaries.

The Credit Agreement was amended on May 30, 2008 to provide for a $177.5 million working capital facility, a $100 million term loan, and a $35 million revolving credit facility. On January 24, 2011, the Borrowers amended and restated the Credit Agreement (the “Fifth Amended Credit Agreement”) to decrease the working capital facility to $150 million , to increase the term loan to $130 million and to eliminate the revolving credit facility.

On December 17, 2012, the Borrowers amended and restated the Fifth Amended Credit Agreement to decrease the working capital facility to $70 million , to decrease the term loan to $125 million and to reinstate the revolving credit facility in the amount of $30 million (the “Sixth Amended Credit Agreement”).

On July 31, 2013 and in conjunction with the initial public offering of Marlin Midstream Partners, LP (“Marlin”), which was formerly a wholly owned subsidiary of Spark Energy Ventures, the Sixth Amended Credit Agreement was amended and restated to increase the working capital facility to $80 million and eliminate the term loan and revolving credit facility (the “Seventh Amended Credit Agreement”) and to remove Marlin as a party to the Credit Agreement. The Seventh Amended Credit Agreement was scheduled to mature on July 31, 2015. The Seventh Amended Credit Agreement continued to be secured by the assets of Spark Energy Ventures and its subsidiaries through completion of the Offering.

Although SE and SEG, as wholly owned subsidiaries of Spark Energy Ventures, were jointly and severally liable for Marlin’s borrowing under the Sixth Amended Credit Agreement prior to the Marlin initial public offering, SE and SEG did not historically have access to or use the term loan and the revolving credit facility utilized by Marlin. SE and SEG were the primary recipients of the proceeds from the working capital facility.

Prior to the Offering - Working Capital Facility

The working capital facility was $150 million in 2012 under the Fifth Amended Credit Agreement and was later amended to $70 million on December 17, 2012 under the Sixth Amended Credit Agreement. On July 31, 2013, and in conjunction with the Seventh Amended Credit Agreement, the working capital facility was increased to $80 million .

The working capital facility was available for use by Spark Energy Ventures and its affiliates to finance the working capital requirements related to the purchase and sale of natural gas, electricity, and other commodity products not related to the retail natural gas and asset optimization and retail electricity businesses of the Company. The Company’s condensed combined and consolidated financial statements included the total amounts outstanding under the working capital facility of $27.5 million as December 31, 2013 , which was classified as current in the condensed combined balance sheet as the working capital facility was drawn upon and repaid on a monthly basis to fund working capital needs. Portions of the borrowings were used to fund equity distributions to the sole member of the Company to fund unrelated operations of an affiliate under the common control of the sole member prior to the Offering. The total amounts outstanding under the facility as of December 31, 2013 and through the Offering date included $29.0 million that was retained and paid off by an affiliate in connection with the Offering.

Further, through the issuance of letters of credit, the Company was able to secure payment to suppliers. No obligation is recorded for such outstanding letters of credit unless they are drawn upon by the suppliers and in the event a supplier draws on a letter of credit, repayment is due by the earlier of demand by the bank or at the expiration of the applicable Credit Agreement. Under the working capital facility, the Company paid a fee with respect to each letter of credit issued and outstanding.

Under the Sixth Amended Credit Agreement, the Company was able to elect to have loans under the working credit facility bear interest either (i) at a Eurodollar-based rate plus a margin ranging from 3.00% to 3.75% depending on the Company’s consolidated funded indebtedness ratio then in effect, or (ii) at a base rate loan plus a margin ranging from 2.00% to 2.75% depending on the Company’s consolidated funded indebtedness ratio then in effect. The Company also paid a nonutilization fee equal to 0.50% per annum.

Under the Seventh Amended Credit Agreement, the Company was able to elect to have loans under the working capital facility bear interest (i) at a Eurodollar-based rate plus a margin ranging from 3.00% to 3.25% , depending on the Spark Energy Ventures’ aggregate amount outstanding then in effect, (ii) at a base rate loan plus a margin ranging from 2.00% to 2.25% , depending on Spark Energy Ventures’ aggregate amount outstanding then in effect or (iii) a cost of funds rate loan plus a margin ranging from 2.50% to 2.75% , depending on Spark Energy Ventures’ aggregate amount outstanding then in effect. Each working capital loan made as a result of a drawing under a letter of credit bears interest on the outstanding principal amount thereof from the date funded at a floating rate per annum equal to the cost of funds rate plus the applicable margin until such loan has been outstanding for more than two business days and, thereafter, bears interest on the outstanding principal amount thereof at a floating rate per annum equal to the base rate plus the applicable margin, plus 2.00% per annum. The Company also paid a commitment fee equal to 0.50% per annum.

Prior to the Offering - NuDevco Note

NuDevco Retail Holdings transferred Spark HoldCo units to the Company for the $50,000 NuDevco Note, and the limited liability company agreement of Spark HoldCo was amended and restated to admit Spark Energy, Inc. as its sole managing member. This promissory note was repaid in connection with proceeds from the Offering.

Senior Credit Facility Executed at the Offering

Concurrently with the closing of the Offering, the Company entered into a new $70.0 million senior secured revolving credit facility (“Senior Credit Facility”), which was set to mature on August 1, 2016. If no event of default has occurred, the Company has the right, subject to approval by the administrative agent and each issuing bank, to increase the commitments under the Senior Credit Facility up to $120.0 million . The Company borrowed approximately $10.0 million under the Senior Credit Facility at the closing of the Offering to repay in full the outstanding indebtedness under the Seventh Amended Credit Agreement that SEG and SE agreed to be responsible for pursuant to an interborrower agreement between SEG, SE and an affiliate. The remaining $29.0 million of indebtedness outstanding under the Seventh Amended Credit Agreement at the Offering date was paid down by our affiliate with its own funds concurrent with the closing of the Offering pursuant to the terms of the interborrower agreement. Following this repayment, the Seventh Amended Credit Agreement was terminated. The Company had $15 million in letters of credit outstanding under the Senior Credit Facility at inception.

On July 8, 2015, the Company as guarantor, and Spark HoldCo (the “Borrower," and together with the subsidiaries of Spark HoldCo, the “Co-Borrowers”) amended and restated the Senior Credit Facility to include a senior secured revolving working capital facility of $60.0 million ("Working Capital Line") and a secured revolving line of credit of $25.0 million ("Acquisition Line") to be used specifically for the financing of up to 75% of the cost of acquisitions with the remainder to be financed by the Company either through cash on hand or the issuance of subordinated debt. The Senior Credit Facility will mature on July 8, 2017 and may be extended for one additional year with lender consent. Borrowings under the Acquisition Line will be repaid 25% per year with the remaining 50% due at maturity. The Company borrowed $16.6 million utilized in the closing of the CenStar acquisition, and on July 31, 2015, the Company borrowed an additional $15.0 million utilized in the closing of the Oasis acquisition. Refer to Note 3 "Acquisitions" for further discussion.

At the Borrower’s election, interest under the Working Capital Line is generally determined by reference to:

 

The interest rate is generally reduced by 25 basis points if utilization under the Working Capital Line is below fifty percent. Borrowings under the Acquisition Line are generally determined by reference to:

The Co-Borrowers pay an annual commitment fee of 0.375% or 0.5% on the unused portion of the Working Capital Line depending upon the unused capacity and 0.5% on the unused portion of the Acquisition Line. The lending syndicate under the Senior Credit Facility will be entitled to several additional fees including an upfront fee, annual agency fee, and fronting fees based on a percentage of the face amount of letters of credit payable to any syndicate member that issues a letter a credit.

The Company has the ability to elect the availability under the Working Capital Line between $30.0 million to $60.0 million . Availability under the working capital line will be subject to borrowing base limitations. The borrowing base is calculated primarily based on 80% to 90% of the value of eligible accounts receivable and unbilled product sales (depending on the credit quality of the counterparties) and inventory and other working

capital assets. The Co-Borrowers must generally seek approval of the Agent or the lenders for permitted acquisitions to be financed under the Acquisition Line.

The Senior Credit Facility is secured by pledges of the equity of the portion of Spark HoldCo owned by the Company and of the equity of Spark HoldCo’s subsidiaries and the Co-Borrowers’ present and future subsidiaries, all of the Co-Borrowers’ and their subsidiaries’ present and future property and assets, including accounts receivable, inventory and liquid investments, and control agreements relating to bank accounts. The Senior Credit Facility also contains covenants that, among other things, require the maintenance of specified ratios or conditions as follows:

Minimum Net Working Capital. The Co-Borrowers must maintain minimum consolidated net working capital at all times equal to $2.0 million initially and gradually increasing to the greater of $5.0 million or 15% of the elected availability under the Working Capital Line.

 

Minimum Adjusted Tangible Net Worth. Spark Energy, Inc. must maintain a minimum consolidated adjusted tangible net worth at all times equal to the net proceeds from equity issuances occurring after the date of the Senior Credit Facility plus the greater of (i)  20% of aggregate commitments under the Working Capital Line plus 33% of borrowings under the Acquisition Line and (ii)  $18.0 million .

Minimum Fixed Charge Coverage Ratio. Spark Energy, Inc. must maintain a minimum fixed charge coverage ratio of 1.10 to 1 (with quarterly increases to the numerator of increments of 0.05 beginning in the third quarter of 2016). The Fixed Charge Coverage Ratio is defined as the ratio of (a) Adjusted EBITDA to (b) the sum of consolidated interest expense (other than interest paid-in-kind in respect of any Subordinated Debt), letter of credit fees, commitment fees, acquisition earn-out payments, distributions and scheduled amortization payments.

Maximum Total Leverage Ratio. Spark Energy, Inc. must maintain a ratio of total indebtedness (excluding the Working Capital Facility and qualifying subordinated debt) to Adjusted EBITDA of a maximum of 2.50 to 1. The Senior Credit Facility contains various negative covenants that limit the Company’s ability to, among other things, do any of the following:

Spark Energy, Inc. is entitled to pay cash dividends to the holders of the Class A common stock and Spark HoldCo will be entitled to make cash distributions to NuDevco Retail Holdings, LLC so long as: (a) no default exists or would result from such a payment; (b) the Co-Borrowers are in pro forma compliance with all financial covenants before and after giving effect to such payment and (c) the outstanding amount of all loans and letters of credit does not exceed the borrowing base limits. Spark HoldCo’s inability to satisfy certain financial covenants or the existence of an event of default, if not cured or waived, under the Senior Credit Facility could prevent the Company from paying dividends to holders of the Class A common stock.

The Senior Credit Facility contains certain customary representations and warranties and events of default. Events of default include, among other things, payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults and cross-acceleration to certain indebtedness, change in control in which affiliates of W. Keith Maxwell III own less than 40% of the outstanding voting interests in the Company, certain events of bankruptcy, certain events under ERISA, material judgments in excess of $5.0 million , certain events with respect

to material contracts, actual or asserted failure of any guaranty or security document supporting the Senior Credit Facility to be in full force and effect and changes of control. If such an event of default occurs, the lenders under the Senior Credit Facility would be entitled to take various actions, including the acceleration of amounts due under the facility and all actions permitted to be taken by a secured creditor.

The Senior Credit Facility is secured by the equity interests of SE, SEG, Spark HoldCo, Oasis and CenStar (the “Co-Borrowers”) present and future subsidiaries, all of the Co-Borrowers’ and their subsidiaries’ present and future property and assets, including accounts receivable, inventory and liquid investments, and control agreements relating to bank accounts.

In addition, the Senior Credit Facility contains affirmative covenants that are customary for credit facilities of this type. The covenants include delivery of financial statements (including any filings made with the SEC, maintenance of property and insurance, payment of taxes and obligations, material compliance with laws, inspection of property, books and records and audits, use of proceeds, payments to bank blocked accounts, notice of defaults and certain other customary matters.

Convertible Subordinated Notes to Affiliate

In connection with the financing of the CenStar acquisition, the Company, together with Spark HoldCo, issued the CenStar Note to Retailco for $2.1 million on July 8, 2015. The CenStar Note matures on July 8, 2020, and bears interest at an annual rate of 5% , payable semiannually. The Company has the right to pay interest in kind at its option. The CenStar Note is convertible into shares of the Company’s Class B common stock, par value $0.01 per share (and a related unit of Spark HoldCo) at a conversion price of $16.57 per share. Retailco may not exercise conversion rights for the first eighteen months after the CenStar Note is issued. The CenStar Note is subject to automatic conversion upon a sale of the Company. The CenStar Note is subordinated in certain respects to the Senior Credit Facility pursuant to a subordination agreement. The Company may pay interest and prepay principal so long as the Company is in compliance with its covenants; is not in default under the Senior Credit Facility and has minimum availability of $5.0 million under its borrowing base under the Senior Credit Facility. Shares of Class A common stock resulting from the conversion of the shares of Class B common stock issued as a result of the conversion right under the CenStar Note will be entitled to registration rights identical to the registration rights currently held by NuDevco on shares of Class A common stock it receives upon conversion of its existing shares of Class B common stock.

In connection with the financing of the Oasis acquisition, the Company, together with Spark HoldCo, issued the Oasis Note to Retailco for $5.0 million on July 31, 2015. The Oasis Note matures on July 31, 2020, and bears interest at an annual rate of 5% , payable semiannually. The Company has the right to pay-in-kind any interest at its option. The Oasis Note is convertible into shares of the Company's Class B common stock, par value $0.01 per share (and a related unit of Spark HoldCo) at a conversion price of $14.00 per share. Retailco may not exercise conversion rights for the first eighteen months after the Oasis Note is issued. The Oasis Note is subject to automatic conversion upon a sale of the Company. The Oasis Note is subordinated in certain respects to the Senior Credit Facility pursuant to a subordination agreement. The Company may pay interest and prepay principal so long as the Company is in compliance with its covenants; is not in default under the Senior Credit Facility and has minimum availability of $5.0 million under its borrowing base under the Senior Credit Facility. Shares of Class A common stock resulting from the conversion of the shares of Class B common stock issued as a result of the conversion right under the Oasis Note will be entitled to registration rights identical to the registration rights currently held by NuDevco on shares of Class A common stock it receives upon conversion of its existing shares of Class B common stock.

The conversion rate of $14.00 per share for the Oasis Note was fixed as of the date of the execution of the Oasis acquisition agreement on May 12, 2015. Due to a rise in the price of our common stock from May 12, 2015 to the closing of Oasis acquisition on July 31, 2015, the conversion rate of $14.00 per share was below the market price per share of Class A common stock of $16.21 on the issuance date of the Oasis Note on July 31, 2015. As a result, the Company assessed the Oasis Note for a beneficial conversion feature. Due to this conversion feature being "in-the-money" upon issuance, we recognized a beneficial conversion feature based on its intrinsic value of $0.8

million as a discount to the Oasis Note and as additional paid-in capital. This discount will be amortized as interest expense under the effective interest method over the life of the Oasis Note.

Balance Sheet and Income Statement Summary

Debt consists of the following amounts as of (in thousands):

(1)    Includes unamortized discount of $0.8 million at September 30, 2015 related to a beneficial conversion feature of the Oasis Note.

6. Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. Fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. This includes not only the credit standing of counterparties involved and the impact of credit enhancements but also the impact of the Company’s own nonperformance risk on its liabilities.

The Company applies fair value measurements to its commodity derivative instruments and a contingent payment arrangement based on the following fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels:

As the fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable data (Level 3), the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. In these cases, the lowest level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents assets and liabilities measured and recorded at fair value in the Company’s condensed combined and consolidated balance sheets on a recurring basis by and their level within the fair value hierarchy as of (in thousands):  

The Company had no transfers of assets or liabilities between any of the above levels during the nine months ended September 30, 2015 and the year ended December 31, 2014 .

The Company’s derivative contracts include exchange-traded contracts fair valued utilizing readily available quoted market prices and non-exchange-traded contracts fair valued using market price quotations available through brokers or over-the-counter and on-line exchanges. In addition, in determining the fair value of the Company’s derivative contracts, the Company applies a credit risk valuation adjustment to reflect credit risk which is calculated based on the Company’s or the counterparty’s historical credit risks. As of September 30, 2015 and December 31, 2014 , the credit risk valuation adjustment was not material.

The contingent payment arrangement referred to above reflects the CenStar Earnout, which is recorded in other current liabilities in the condensed consolidated balance sheet and discussed in Note 3 "Acquisitions." The CenStar Earnout is based on a financial measurement attributable to the operations of CenStar for the year following the closing of the acquisition. In determining the fair value of the CenStar Earnout, the Company forecasted this one year performance measurement, as defined by the CenStar stock purchase agreement. As this performance measurement is based on the Company's internal forecasts, we have classified the CenStar Earnout as a Level 3 measurement. There have been no changes to our estimate of the CenStar Earnout since its initial recognition on July 8, 2015 in connection with the CenStar acquisition.

Other Financial Instruments

The carrying amount of cash and cash equivalents, accounts receivable, accounts receivable-affiliates, accounts payable, accounts payable-affiliates, and accrued liabilities recorded in the condensed combined and consolidated balance sheets approximate fair value due to the short-term nature of these items. The carrying amount of long-term debt recorded in the condensed combined and consolidated balance sheets approximates fair value because of the variable rate nature of the Company’s long-term debt. The fair value of our convertible subordinated notes is not determinable due to the affiliate nature and terms of the associated debt instrument with the affiliate. The fair value of the payable pursuant to tax receivable agreement—affiliate is not determinable due to the affiliate nature and terms of the associated agreement with the affiliate.

7. Accounting for Derivative Instruments

The Company is exposed to the impact of market fluctuations in the price of electricity and natural gas and basis costs, storage and ancillary capacity charges from independent system operators. The Company uses derivative instruments to manage exposure to these risks, and historically designated certain derivative instruments as cash flow hedges for accounting purposes. For derivatives designated in a qualifying cash flow hedging relationship, the effective portion of the change in fair value is recognized in accumulated other comprehensive income (“OCI”) and reclassified to earnings in the period in which the hedged item affects earnings. Any ineffective portion of the derivative’s change in fair value is recognized currently in earnings. As of September 30, 2015 and December 31, 2014, the Company had not designated any derivative instruments as cash flow hedges.

The Company also holds certain derivative instruments that are not held for trading purposes but are also not designated as hedges for accounting purposes. These derivative instruments represent economic hedges that mitigate the

Company’s exposure to fluctuations in commodity prices. For these derivative instruments, changes in the fair value are recognized currently in earnings in retail revenues or retail cost of revenues.

As part of the Company’s strategy to optimize its assets and manage related risks, it also manages a portfolio of commodity derivative instruments held for trading purposes. The Company’s commodity trading activities are subject to limits within the Company’s Risk Management Policy. For these derivative instruments, changes in the fair value are recognized currently in earnings in net asset optimization revenues.

Derivative assets and liabilities are presented net in the Company’s condensed combined and consolidated balance sheets when the derivative instruments are executed with the same counterparty under a master netting arrangement. The Company’s derivative contracts include transactions that are executed both on an exchange and centrally cleared as well as over-the-counter, bilateral contracts that are transacted directly with a third party. To the extent the Company has paid or received collateral related to the derivative assets or liabilities, such amounts would be presented net against the related derivative asset or liability’s fair value. As of September 30, 2015 and December 31, 2014, the Company had paid zero in collateral. The specific types of derivative instruments the Company may execute to manage the commodity price risk include the following:

The Company has entered into other energy-related contracts that do not meet the definition of a derivative instrument or qualify for the normal purchase or normal sale exception 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. 

In connection with the acquisitions of Oasis and CenStar, the Company novated their existing transactions for the purchase and sale of gas and power over to SE and SEG.
