Matador Resources Company and Subsidiaries
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -
UNAUDITED
NOTE 1 - NATURE OF OPERATIONS
Matador Resources Company, a Texas corporation (“Matador” and, collectively with its subsidiaries, the “Company”), is an independent energy company engaged in the exploration, development, production and acquisition of oil and natural gas resources in the United States, with an emphasis on oil and natural gas shale and other unconventional plays. The Company’s current operations are focused primarily on the oil and liquids-rich portion of the Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. The Company also operates in the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley plays in Northwest Louisiana and East Texas. Additionally, the Company conducts midstream operations, primarily through its midstream joint venture, San Mateo Midstream, LLC (“San Mateo” or the “Joint Venture”), in support of the Company’s exploration, development and production operations and provides natural gas processing, natural gas, oil and salt water gathering services and salt water disposal services to third parties on a limited basis.
NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Interim Financial Statements, Basis of Presentation, Consolidation and Significant Estimates
The interim unaudited condensed consolidated financial statements of Matador and its subsidiaries have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) but do not include all of the information and footnotes required by generally accepted accounting principles in the United States of America (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (the “Annual Report”) filed with the SEC. The Company consolidates certain subsidiaries and joint ventures that are less than wholly owned and are not involved in oil and natural gas exploration, including San Mateo, and the net income and equity attributable to the non-controlling interest in these subsidiaries have been reported separately as required by Accounting Standards Codification (“ASC”) 810. The Company proportionately consolidates certain joint ventures that are less than wholly owned and are involved in oil and natural gas exploration. All intercompany accounts and transactions have been eliminated in consolidation. In management’s opinion, these interim unaudited condensed consolidated financial statements include all adjustments, consisting only of normal, recurring adjustments, which are necessary for a fair presentation of the Company’s interim unaudited condensed consolidated financial statements as of March 31, 2017. Amounts as of December 31, 2016 are derived from the Company’s audited consolidated financial statements in the Annual Report.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions may also affect disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s interim unaudited condensed consolidated financial statements are based on a number of significant estimates, including accruals for oil and natural gas revenues, accrued assets and liabilities primarily related to oil and natural gas operations, stock-based compensation, valuation of derivative instruments and oil and natural gas reserves. The estimates of oil and natural gas reserves quantities and future net cash flows are the basis for the calculations of depletion and impairment of oil and natural gas properties, as well as estimates of asset retirement obligations and certain tax accruals. While the Company believes its estimates are reasonable, changes in facts and assumptions or the discovery of new information may result in revised estimates. Actual results could differ from these estimates.
Reclassifications
Certain reclassifications have been made to the prior periods’ financial statements to conform to the current period presentation. As a result of the growth of the Company’s midstream operations, these operations met the required threshold for segment reporting. As a result, $0.5 million for the three months ended March 31, 2016 was reclassified from other income to third-party midstream services revenues. In addition, $1.0 million related to midstream operating costs for the three months ended March 31, 2016 was reclassified from lease operating expenses to plant and other midstream services operating expenses. These reclassifications had no effect on previously reported results of operations, cash flows or retained earnings.
Property and Equipment
The Company uses the full-cost method of accounting for its investments in oil and natural gas properties. Under this method, the Company is required to perform a ceiling test each quarter that determines a limit, or ceiling, on the capitalized costs of oil and natural gas properties based primarily on the after-tax estimated future net cash flows from oil and natural gas properties using a 10% discount rate and the arithmetic average of first-day-of-the-month oil and natural gas prices for the prior 12-month period. For the three months ended March 31, 2017, the cost center ceiling was higher than the capitalized costs of oil and natural gas properties; no impairment charge was necessary. However, due primarily to declines in oil and natural gas

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
prices in early 2016, the capitalized costs of oil and natural gas properties exceeded the cost center ceiling for the three months ended March 31, 2016, and as a result, the Company recorded an impairment charge to its net capitalized costs of $80.5 million in its interim unaudited condensed consolidated statements of operations for the three months ended March 31, 2016.
The Company capitalized approximately $5.6 million and $2.0 million of its general and administrative costs for the three months ended March 31, 2017 and 2016, respectively, and approximately $1.2 million and $0.4 million of its interest expense for the three months ended March 31, 2017 and 2016, respectively.
Earnings (Loss) Per Common Share
The Company reports basic earnings (loss) attributable to Matador Resources Company shareholders per common share, which excludes the effect of potentially dilutive securities, and diluted earnings (loss) attributable to Matador Resources Company shareholders per common share, which includes the effect of all potentially dilutive securities unless their impact is anti-dilutive.
The following table sets forth the computation of diluted weighted average common shares outstanding for the three months ended March 31, 2017 and 2016 (in thousands).

| Three Months Ended March 31,
2017 |  | 2016
Weighted average common shares outstanding |  |  |
Basic | 99,799 |  |  | 85,305 |
Dilutive effect of options, restricted stock units and preferred shares | 499 |  |  | — |
Diluted weighted average common shares outstanding | 100,298 |  |  | 85,305 |

A total of 3.0 million options to purchase shares of the Company’s common stock and 0.1 million restricted stock units were excluded from the diluted weighted average common shares outstanding for the three months ended March 31, 2016 because their effects were anti-dilutive. Additionally, 1.0 million restricted shares, which are participating securities, were excluded from the calculations above for the three months ended March 31, 2016, as the security holders do not have the obligation to share in the losses of the Company.
Recent Accounting Pronouncements
Revenue from Contracts with Customers. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), which specifies how and when to recognize revenue. This standard requires expanded disclosures surrounding revenue recognition and is intended to improve, and converge with international standards, the financial reporting requirements for revenue from contracts with customers. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09 for one year to fiscal years beginning after December 15, 2017. Early adoption is permitted for fiscal years beginning after December 15, 2016. In May 2016, the FASB issued ASU 2016-11, which rescinds guidance from the SEC on accounting for gas balancing arrangements and will eliminate the use of the entitlements method. Entities have the option of using either a full retrospective or modified approach to adopt the new standards. In December 2016, the FASB issued ASU 2016-20, which clarifies disclosure requirements in ASU 2014-09. The Company expects to adopt the new guidance effective January 1, 2018 using the modified approach. The Company is evaluating the new guidance, including (i) identification of revenue streams and (ii) review of contracts and procedures currently in place.
Leases. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP. This ASU will become effective for fiscal years beginning after December 15, 2018 with early adoption permitted. Entities are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. The Company is currently evaluating the impact of the adoption of this ASU on its consolidated financial statements.

Statement of Cash Flows. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230), which specifies that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. This ASU will become effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The update should be applied using a retrospective transition method to each period presented. The Company believes that the impact of the adoption of this ASU will change the presentation of its beginning and ending cash balances on its Consolidated Statements of Cash Flows and eliminate the presentation of changes in restricted cash balances from investing activities on its Consolidated Statements of Cash Flows.
Clarifying the Definition of a Business. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805), which specifies the minimum inputs and processes required for an integrated set of assets and activities to meet the definition of a business. This ASU will become effective for fiscal years beginning after December 15, 2017 with early adoption permitted. Entities are required to apply guidance prospectively upon adoption. The Company is currently evaluating the impact of the adoption of this ASU on its consolidated financial statements.
NOTE 3 – BUSINESS COMBINATION
Joint Venture
On February 17, 2017, the Company contributed substantially all of its midstream assets located in the Rustler Breaks (Eddy County, New Mexico) and Wolf (Loving County, Texas) asset areas in the Delaware Basin to San Mateo, a joint venture with a subsidiary of Five Point Capital Partners LLC (“Five Point”). The midstream assets contributed to San Mateo include (i) the Black River cryogenic natural gas processing plant in the Rustler Breaks asset area (the “Black River Processing Plant”); (ii) one salt water disposal well and a related commercial salt water disposal facility in the Rustler Breaks asset area; (iii) three salt water disposal wells and related commercial salt water disposal facilities in the Wolf asset area; and (iv) substantially all related oil, natural gas and water gathering systems and pipelines in both the Rustler Breaks and Wolf asset areas (collectively, the “Delaware Midstream Assets”). The Company continues to operate the Delaware Midstream Assets. The Company retained its ownership in certain midstream assets in South Texas and Northwest Louisiana, which are not part of the Joint Venture.
The Company and Five Point own 51% and 49% of the Joint Venture, respectively. Five Point provided initial cash consideration of $176.4 million to the Joint Venture in exchange for its 49% interest. Approximately $171.5 million of this cash contribution by Five Point was distributed by the Joint Venture to the Company as a special distribution. The Company may earn an additional $73.5 million in performance incentives over the next five years. The Company contributed the Delaware Midstream Assets and $5.1 million in cash to the Joint Venture in exchange for its 51% interest. The parties to the Joint Venture have also committed to spend up to an additional $140.0 million in the aggregate to expand the Joint Venture’s midstream operations and asset base. The Joint Venture is consolidated in the Company’s interim unaudited condensed consolidated financial statements with Five Point’s interest in the Joint Venture being accounted for as a non-controlling interest.
In connection with the Joint Venture, the Company dedicated its current and future leasehold interests in the Rustler Breaks and Wolf asset areas pursuant to 15-year, fixed-fee natural gas, oil and salt water gathering agreements and salt water disposal agreements, effective as of February 1, 2017. In addition, the Company dedicated its current and future leasehold interests in the Rustler Breaks asset area pursuant to a 15-year, fixed fee natural gas processing agreement (see Note 10).

NOTE 5 - DEBT
At March 31, 2017 and May 3, 2017, the Company had $575.0 million of outstanding 6.875% senior notes due 2023, no borrowings outstanding under the Company’s revolving credit agreement (the “Credit Agreement”) and approximately $0.8 million in outstanding letters of credit issued pursuant to the Credit Agreement.
Credit Agreement
The borrowing base under the Credit Agreement is determined semi-annually as of May 1 and November 1 by the lenders based primarily on the estimated value of the Company’s proved oil and natural gas reserves at December 31 and June 30 of each year, respectively. Both the Company and the lenders may request an unscheduled redetermination of the borrowing base once each between scheduled redetermination dates. During the first quarter of 2017, the lenders completed their review of the Company’s proved oil and natural gas reserves at December 31, 2016, and on April 28, 2017, the borrowing base was increased to $450.0 million and the maximum facility amount remained at $500.0 million. The Company elected to keep the borrowing commitment at $400.0 million. Borrowings under the Credit Agreement are limited to the least of the borrowing base, the maximum facility amount and the elected commitment. The Credit Agreement matures on October 16, 2020.
In the event of an increase in the elected commitment, the Company is required to pay a fee to the lenders equal to a percentage of the amount of the increase, which is determined based on market conditions at the time of the increase. Total deferred loan costs were $1.2 million at March 31, 2017, and these costs are being amortized over the term of the Credit Agreement, which approximates amortization of these costs using the effective interest method. If, upon a redetermination of the borrowing base, the borrowing base were to be less than the outstanding borrowings under the Credit Agreement at any time, the Company would be required to provide additional collateral satisfactory in nature and value to the lenders to increase the borrowing base to an amount sufficient to cover such excess or to repay the deficit in equal installments over a period of six months.
The Company believes that it was in compliance with the terms of the Credit Agreement at March 31, 2017.
Senior Unsecured Notes
On April 14, 2015 and December 9, 2016, the Company issued $400.0 million and $175.0 million, respectively, of 6.875% senior notes due 2023 (collectively, the “Notes”). The Notes mature on April 15, 2023, and interest is payable semi-annually in arrears on April and October 15 of each year.
On February 17, 2017, in connection with the formation of San Mateo (see Note 3), Matador entered into a Fourth Supplemental Indenture (the “Fourth Supplemental Indenture”), which supplements the indenture governing the Notes. Pursuant to the Fourth Supplemental Indenture, (i) Longwood Midstream Holdings, LLC, the holder of Matador’s 51% equity interest in San Mateo, was designated as a guarantor of the Notes and (ii) DLK Black River Midstream, LLC and Black River Water Management Company, LLC, each subsidiaries of San Mateo, were released as parties to, and as guarantors of, the Notes. The guarantors of the Notes, following the effectiveness of the Fourth Supplemental Indenture, are referred to herein as the “Guarantor Subsidiaries.” San Mateo

NOTE 6 - INCOME TAXES
The Company’s deferred tax assets exceed its deferred tax liabilities due to the deferred tax assets generated by the full-cost ceiling impairment charges recorded in prior periods; as a result, the Company established a valuation allowance against most of the deferred tax assets beginning in the third quarter of 2015. The Company retained a full valuation allowance at March 31, 2017 due to uncertainties regarding the future realization of its deferred tax assets. The valuation allowance will continue to be recognized until the realization of future deferred tax benefits are more likely than not to be utilized.
NOTE 7 - STOCK-BASED COMPENSATION
In February 2017, the Company granted awards of 228,174 shares of restricted stock and options to purchase 590,128 shares of the Company’s common stock at an exercise price of $27.26 per share to certain of its employees. The fair value of these awards was approximately $12.4 million. All of these awards vest ratably over three years. In February 2017, the Company also granted awards of 174,561 shares of restricted stock and options to purchase 444,491 shares of the Company’s common stock at an exercise price of $26.86 per share to certain of its employees. The fair value of these awards was approximately $9.3 million. All of these awards vest ratably over three years.

NOTE 9 - FAIR VALUE MEASUREMENTS
The Company measures and reports certain financial and non-financial assets and liabilities on a fair value basis. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Fair value measurements are classified and disclosed in one of the following categories.

Level 1 | Unadjusted quoted prices for identical, unrestricted assets or liabilities in active markets.

Level 2 | Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. This category includes those derivative instruments that are valued with industry standard models that consider various inputs including: (i) quoted forward prices for commodities, (ii) time value of money and (iii) current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these inputs are observable in the marketplace throughout the full term of the derivative instrument and can be derived from observable data or supported by observable levels at which transactions are executed in the marketplace.

Level 3 | Unobservable inputs that are not corroborated by market data that reflect a company’s own market assumptions.

Financial and non-financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels.
The following tables summarize the valuation of the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis in accordance with the classifications provided above as of March 31, 2017 and December 31, 2016 (in thousands).

NOTE 10 - COMMITMENTS AND CONTINGENCIES
Processing, Transportation and Salt Water Disposal Commitments
Eagle Ford
Effective September 1, 2012, the Company entered into a firm five-year natural gas processing and transportation agreement whereby the Company committed to transport the anticipated natural gas production from a significant portion of its Eagle Ford acreage in South Texas through the counterparty’s system for processing at the counterparty’s facilities. The agreement also includes firm transportation of the natural gas liquids extracted at the counterparty’s processing plant downstream for fractionation. After processing, the residue natural gas is purchased by the counterparty at the tailgate of its processing plant and further transported under its natural gas transportation agreements. The arrangement contains fixed processing and liquids transportation and fractionation fees, and the revenue the Company receives varies with the quality of natural gas transported to the processing facilities and the contract period.
Under this agreement, if the Company does not meet 80% of the maximum thermal quantity transportation and processing commitments in a contract year, it will be required to pay a deficiency fee per MMBtu of natural gas deficiency. Any quantity in excess of the maximum MMBtu delivered in a contract year can be carried over to the next contract year for purposes of calculating the natural gas deficiency. During certain prior periods, the Company had an immaterial natural gas deficiency, and the counterparty to this agreement waived the deficiency fee. The Company paid $0.5 million and $0.9 million in processing and transportation fees under this agreement during the three months ended March 31, 2017 and 2016, respectively. The future undiscounted minimum payment under this agreement as of March 31, 2017 was $0.6 million.
Delaware Basin — Loving County, Texas Natural Gas Processing
In late 2015, the Company entered into a 15-year, fixed-fee natural gas gathering and processing agreement whereby the Company committed to deliver the anticipated natural gas production from a significant portion of its Loving County, Texas acreage in West Texas through the counterparty’s gathering system for processing at the counterparty’s facilities. Under this agreement, if the Company does not meet the volume commitment for transportation and processing at the facilities in a contract year, it will be required to pay a deficiency fee per MMBtu of natural gas deficiency. At the end of each year of the agreement, the Company can elect to have the previous year’s actual transportation and processing volumes be the new minimum commitment for each of the remaining years of the contract. As such, the Company has the ability to unilaterally reduce the gathering and processing commitment if the Company’s production in the Loving County area is less than the Company’s currently projected production. If the Company ceased operations in this area at March 31, 2017, the total deficiency fee required to be paid would be approximately $11.7 million. In addition, if the Company elects to reduce the gathering and processing commitment in any year, the Company has the ability to elect to increase the committed volumes in any future year to the originally agreed gathering and processing commitment. Any quantity in excess of the volume commitment delivered in a contract year can be carried over to the next contract year for purposes of calculating the natural gas deficiency. The Company paid approximately $3.2 million and $2.0 million in natural gas processing and gathering fees under

this agreement during the three months ended March 31, 2017 and 2016, respectively. The Company can elect to either sell the residue gas to the counterparty at the tailgate of its processing plants or have the counterparty deliver to the Company the residue gas in-kind to be sold to third parties downstream of the plants.
Delaware Basin — San Mateo
In connection with the Joint Venture, effective as of February 1, 2017, the Company dedicated its current and future leasehold interests in the Rustler Breaks and Wolf asset areas pursuant to 15-year, fixed-fee natural gas, oil and salt water gathering agreements and salt water disposal agreements. In addition, the Company dedicated its current and future leasehold interests in the Rustler Breaks asset area pursuant to a 15-year, fixed-fee natural gas processing agreement (collectively with the gathering and salt water disposal agreements, the “Operational Agreements”). The Joint Venture will provide the Company with firm service under each of the Operational Agreements in exchange for certain minimum volume commitments. The minimum contractual obligation under the Operational Agreements at March 31, 2017 was approximately $267.3 million.
On May 2, 2017, a subsidiary of San Mateo entered into an agreement with third parties for the engineering, procurement, construction and installation of an expansion of the Black River Processing Plant. The expansion is expected to be placed into service in 2018. Total commitments under this agreement are $40.9 million. During the three months ended March 31, 2017, the subsidiary of San Mateo made a deposit of $2.0 million to be credited against its obligations under this agreement. As of May 2, 2017, the remaining obligations under this agreement were $38.9 million, which are expected to be incurred within the next year.
Other Commitments
The Company does not own or operate its own drilling rigs, but instead enters into contracts with third parties for such drilling rigs. These contracts establish daily rates for the drilling rigs and the term of the Company’s commitment for the drilling services to be provided, which have typically been for two years or less. The Company would incur a termination obligation if the Company elected to terminate a contract and if the drilling contractor were unable to secure replacement work for the contracted drilling rigs or if the drilling contractor were unable to secure replacement work for the contracted drilling rigs at the same daily rates being charged to the Company prior to the end of their respective contract terms. The Company’s undiscounted minimum outstanding aggregate termination obligations under its drilling rig contracts were approximately $44.6 million at March 31, 2017.
At March 31, 2017, the Company had outstanding commitments to participate in the drilling and completion of various non-operated wells. If all of these wells are drilled and completed as proposed, the Company’s minimum outstanding aggregate commitments for its participation in these non-operated wells were approximately $20.8 million at March 31, 2017. The Company expects these costs to be incurred within the next year.
Legal Proceedings
The Company is a party to several lawsuits encountered in the ordinary course of its business. While the ultimate outcome and impact to the Company cannot be predicted with certainty, in the opinion of management, it is remote that these lawsuits will have a material adverse impact on the Company’s financial condition, results of operations or cash flows.

NOTE 12 - SEGMENT INFORMATION
The Company operates in two business segments: (i) exploration and production and (ii) midstream. The exploration and production segment is engaged in the acquisition, exploration and development of oil and natural gas properties and is currently focused primarily on the oil and liquids-rich portion of the Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. The Company also operates in the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley plays in Northwest Louisiana and East Texas. The midstream segment conducts midstream operations in support of the Company’s exploration, development and production operations and provides natural gas processing, natural gas, oil and salt water gathering services and salt water disposal services to third parties on a limited basis. As of February 17, 2017, substantially all of the Company’s midstream operations in the Rustler Breaks and Wolf asset areas in the Delaware Basin are conducted through San Mateo (see Note 3).
The following tables present selected financial information for the periods presented regarding the Company’s business segments on a stand-alone basis, corporate expenses that are not allocated to a segment and the consolidation and elimination entries necessary to arrive at the financial information for the Company on a consolidated basis (in thousands). On a consolidated basis, midstream services revenues consist primarily of those revenues from midstream operations related to third parties, including working interest owners in the Company’s operated wells. All midstream services revenues associated with Company-owned production are eliminated in consolidation. In evaluating the operating results of the exploration and production and midstream segments, the Company does not allocate certain expenses to the individual segments, including general and administrative expenses. Such expenses are reflected in the column labeled “Corporate.”

Overview
We are an independent energy company founded in July 2003 and engaged in the exploration, development, production and acquisition of oil and natural gas resources in the United States, with an emphasis on oil and natural gas shale and other unconventional plays. Our current operations are focused primarily on the oil and liquids-rich portion of the Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. We also operate in the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley plays in Northwest Louisiana and East Texas. Additionally, we conduct midstream operations, primarily through our midstream joint venture, San Mateo Midstream, LLC (“San Mateo” or the “Joint Venture”), in support of our exploration, development and production operations and provide natural gas processing, natural gas, oil and salt water gathering services and salt water disposal services to third parties on a limited basis.
First Quarter Highlights
For the three months ended March 31, 2017, our total oil equivalent production was 2.97 million BOE, and our average daily oil equivalent production was 32,999 BOE per day, of which 18,323 Bbl per day, or 56%, was oil and 88.1 MMcf per day, or 44%, was natural gas. Our oil production of 1.65 million Bbl for the three months ended March 31, 2017 increased 58% year-over-year from 1.04 million Bbl for the three months ended March 31, 2016. Our natural gas production of 7.9 Bcf for the three months ended March 31, 2017 increased 17% year-over-year from 6.8 Bcf for the three months ended March 31, 2016.
During the first quarter of 2017, our oil and natural gas revenues were $114.8 million, an increase of 161% from oil and natural gas revenues of $43.9 million during the first quarter of 2016. The increase in our oil and natural gas revenues was due to (i) the 37% increase in our total oil equivalent production to 2.97 million BOE in the first quarter of 2017, as compared to 2.17 million BOE produced in the first quarter of 2016 and (ii) the increase in weighted average oil and natural gas prices to $50.72 per Bbl and $3.94 per Mcf, respectively, realized in the first quarter of 2017, as compared to weighted average oil and natural gas prices of $28.89 per Bbl and $2.04 per Mcf, respectively, realized in the first quarter of 2016. The increase in oil and natural gas production was primarily a result of our ongoing delineation and development drilling in the Delaware Basin, which offset declining production in the Eagle Ford and Haynesville shales where we have significantly reduced our activity since 2014 and 2015.
For the first quarter of 2017, we reported net income attributable to Matador Resources Company shareholders of approximately $44.0 million, or $0.44 per diluted common share on a GAAP basis, as compared to a net loss attributable to Matador Resources Company shareholders of $107.7 million, or $1.26 per diluted common share, for the first quarter of 2016.

Table of Contents
For the first quarter of 2017, our Adjusted EBITDA attributable to Matador Resources Company shareholders, a non-GAAP financial measure, was $70.0 million, as compared to Adjusted EBITDA attributable to Matador Resources Company shareholders of $17.2 million during the first quarter of 2016. For a definition of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to our net income (loss) and net cash provided by operating activities, see “— Liquidity and Capital Resources — Non-GAAP Financial Measures.” For more information regarding our financial results for the first quarter of 2017, see “— Results of Operations” below.
During the first quarter of 2017, we operated four drilling rigs in the Delaware Basin. During the first quarter and at May 3, 2017, one of these rigs was drilling in the Wolf/Jackson Trust asset areas in Loving County, Texas, two were drilling in the Rustler Breaks asset area in Eddy County, New Mexico and one was drilling in the Ranger/Arrowhead and Twin Lakes asset areas in Eddy and Lea Counties, New Mexico. We added a fifth drilling rig in the Delaware Basin in late April 2017, and at May 3, 2017, this rig was drilling in the Rustler Breaks asset area.
We began producing oil and natural gas from a total of 14 gross (12.5 net) wells in the Delaware Basin during the first quarter of 2017, including 13 gross (12.4 net) operated and one gross (0.1 net) non-operated horizontal wells. In the Rustler Breaks asset area, we began producing oil and natural gas from a total of eight gross (7.0 net) wells during the first quarter of 2017, including seven gross (6.9 net) operated and one gross (0.1 net) non-operated wells. Of the seven gross operated wells in the Rustler Breaks asset area, two were Wolfcamp A-XY completions, three were lower Wolfcamp B (Blair Shale) completions, one was a Wolfcamp B-Middle completion and one was a Second Bone Spring completion. In the Ranger asset area, we began producing oil and natural gas from a total of four gross (3.9 net) operated wells during the first quarter of 2017. Of the four gross operated wells in the Ranger asset area, one was a Wolfcamp A-Lower completion, two were Second Bone Spring completions and one was a Third Bone Spring completion. In addition, we began producing oil and natural gas from two gross (1.5 net) operated wells in the Wolf/Jackson Trust asset areas during the first quarter of 2017, including one Wolfcamp A-Lower completion and one Second Bone Spring completion.
As a result of our ongoing drilling and completion operations in these asset areas, our Delaware Basin production has continued to increase over the past twelve months. Our total Delaware Basin production for the first quarter of 2017 was 24,535 BOE per day, consisting of 15,685 Bbl of oil per day and 53.1 MMcf of natural gas per day, a 2.5-fold increase from production of 9,958 BOE per day, consisting of 7,172 Bbl of oil per day and 16.7 MMcf of natural gas per day, in the first quarter of 2016. The Delaware Basin contributed approximately 86% of our daily oil production and approximately 60% of our daily natural gas production in the first quarter of 2017, as compared to approximately 63% of our daily oil production and approximately 22% of our daily natural gas production in the first quarter of 2016.
At December 31, 2016, we held approximately 163,700 gross (94,300 net) acres in the Permian Basin in Southeast New Mexico and West Texas, primarily in the Delaware Basin in Lea and Eddy Counties, New Mexico and Loving County, Texas. Between January 1, 2017 and May 3, 2017, we acquired approximately 15,900 gross (9,500 net) acres and approximately 1,000 BOE per day of related production from various lessors, mineral owners and other operators, mostly in and around our existing acreage in the Delaware Basin. Some of this acreage, and a portion of the production, included properties identified at the time of our December 2016 equity and notes offerings. These transactions were pending at the time of those offerings and closed subsequent to December 31, 2016, which contributed to bringing our total Permian Basin acreage position at May 3, 2017 to approximately 178,600 gross (102,300 net) acres, almost all of which was located in the Delaware Basin. We have incurred capital expenditures of approximately $121 million since January 1, 2017 to acquire the acreage and related production. We plan to continue our leasing and acquisition efforts in the Delaware Basin during the remainder of 2017 and may also consider acquiring acreage in the Eagle Ford and Haynesville shales as strategic opportunities are identified.
Midstream Joint Venture
On February 17, 2017, we announced the formation of San Mateo, a strategic joint venture with a subsidiary of Five Point Capital Partners LLC (“Five Point”). The midstream assets contributed to San Mateo include (i) the Black River cryogenic natural gas processing plant in the Rustler Breaks asset area (the “Black River Processing Plant”); (ii) one salt water disposal well and a related commercial salt water disposal facility in the Rustler Breaks asset area; (iii) three salt water disposal wells and related commercial salt water disposal facilities in the Wolf asset area; and (iv) substantially all related oil, natural gas and water gathering systems and pipelines in both the Rustler Breaks and Wolf asset areas (collectively, the “Delaware Midstream Assets”). We received $171.5 million in connection with the formation of the Joint Venture and may earn up to an additional $73.5 million in performance incentives over the next five years. We continue to operate the Delaware Midstream Assets and retain operational control of the Joint Venture. We and Five Point own 51% and 49% of the Joint Venture, respectively. San Mateo will continue to provide firm capacity service to us at market rates, while also being a midstream service provider to third parties in and around our Wolf and Rustler Breaks asset areas.

2017 Capital Expenditure Budget
On March 23, 2017, we adjusted our 2017 capital expenditure budget from between $426 and $454 million to between $456 and $484 million (excluding capital expenditures related to acreage and mineral acquisitions), which reflects our decision to drill and complete a five-well operated program in the Eagle Ford shale in South Texas in order to maintain the leasehold associated with this drilling program and to enhance the value of our Eagle Ford asset. At May 3, 2017, we had begun this five-well Eagle Ford program and anticipate that all five wells will be completed and placed on production late in the second quarter or early in the third quarter of 2017. In addition to drilling these five Eagle Ford wells, our updated 2017 capital expenditure budget includes four drilling rigs operating in the Delaware Basin through late April 2017, when a fifth drilling rig was added in the Delaware Basin. During 2017, we expect to spend $400 to $420 million for drilling, completions and infrastructure and $56 to $64 million for midstream capital expenditures. We expect to direct 93% of our estimated capital expenditure budget (excluding capital expenditures related to acreage and mineral acquisitions) to drilling and completion and midstream activities in the Delaware Basin. For more information regarding our 2017 capital expenditure budget, see “— Liquidity and Capital Resources” below.
Estimated Proved Reserves
The following table sets forth our estimated total proved oil and natural gas reserves at March 31, 2017, December 31, 2016 and March 31, 2016. Our production and proved reserves are reported in two streams: oil and natural gas, including both dry and liquids-rich natural gas. Where we produce liquids-rich natural gas, such as in the Delaware Basin and the Eagle Ford shale, the economic value of the natural gas liquids associated with the natural gas is included in the estimated wellhead natural gas price on those properties where the natural gas liquids are extracted and sold. The reserves estimates were based on evaluations prepared by our engineering staff in accordance with the SEC’s rules for oil and natural gas reserves reporting and do not include any unproved reserves classified as probable or possible that might exist on our properties. In addition, the reserves estimates at December 31, 2016 and March 31, 2016 were audited by an independent reservoir engineering firm, Netherland, Sewell & Associates, Inc.

_______________

(1) | Numbers in table may not total due to rounding.

(2) | Our estimated proved reserves, Standardized Measure and PV-10 were determined using index prices for oil and natural gas, without giving effect to derivative transactions, and were held constant throughout the life of the properties. The unweighted arithmetic averages of the first-day-of-the-month prices for the period from April 2016 through March 2017 were $44.10 per Bbl for oil and $2.73 per MMBtu for natural gas, for the period from January 2016 through December 2016 were $39.25 per Bbl for oil and $2.48 per MMBtu for natural gas and for the period from April 2015 through March 2016 were $42.77 per Bbl for oil and $2.40 per MMBtu for natural gas. These prices were adjusted by property for quality, energy content, regional price differentials, transportation fees, marketing deductions and other factors affecting the price received at the wellhead. We report our proved reserves in two streams, oil and natural gas, and the economic value of the natural gas liquids associated with the natural gas is included in the estimated wellhead natural gas price on those properties where the natural gas liquids are extracted and sold.

(3) | One thousand barrels of oil.

(4) | One billion cubic feet of natural gas.

(5) | One thousand barrels of oil equivalent, estimated using a conversion ratio of one Bbl of oil per six Mcf of natural gas.

(6) | Standardized Measure represents the present value of estimated future net cash flows from proved reserves, less estimated future development, production, plugging and abandonment costs and income tax expenses, discounted at 10% per annum to reflect the timing of future cash flows. Standardized Measure is not an estimate of the fair market value of our properties.

(7) | PV-10 is a non-GAAP financial measure and generally differs from Standardized Measure, the most directly comparable GAAP financial measure, because it does not include the effects of income taxes on future net revenues. PV-10 is not an estimate of the fair market value of our properties. We and others in the industry use PV-10 as a measure to compare the relative size and value of proved reserves held by companies and of the potential return on investment related to the companies’ properties without regard to the specific tax characteristics of such entities. Our PV-10 at March 31, 2017, December 31, 2016 and March 31, 2016 may be reconciled to the Standardized Measure of discounted future net cash flows at such dates by reducing our PV-10 by the discounted future income taxes associated with such reserves. The discounted future income taxes at March 31, 2017, December 31, 2016 and March 31, 2016 were, in millions, $47.0, $6.5 and $6.3, respectively.

At March 31, 2017, our estimated total proved oil and natural gas reserves were 117.1 million BOE, including 62.9 million Bbl of oil and 325.3 Bcf of natural gas, with a Standardized Measure of $810.2 million and a PV-10, a non-GAAP financial measure, of $857.2 million. At December 31, 2016, our estimated total proved oil and natural gas reserves were 105.8 million BOE, including 57.0 million Bbl of oil and 292.6 Bcf of natural gas, and at March 31, 2016, our estimated total proved oil and natural gas reserves were 90.2 million BOE, including 50.7 million Bbl of oil and 236.7 Bcf of natural gas. Our proved oil reserves of 62.9 million Bbl at March 31, 2017 increased 10%, as compared to 57.0 million Bbl at December 31, 2016, and increased 24%, as compared to 50.7 million Bbl at March 31, 2016. At March 31, 2017, approximately 43% of our total proved reserves were proved developed reserves, 54% of our total proved reserves were oil and 46% of our total proved reserves were natural gas.
As a result of our drilling, completion and delineation activities in Southeast New Mexico and West Texas since 2014, our Delaware Basin oil and natural gas reserves have become a more significant component of our total oil and natural gas reserves. Our estimated Delaware Basin proved oil and natural gas reserves have increased 52% from 59.6 million BOE at March 31, 2016, or 66% of our total proved oil and natural gas reserves, including 37.7 million Bbl of oil and 131.6 Bcf of natural gas, to 90.6 million BOE, or 77% of our total proved oil and natural gas reserves, including 52.6 million Bbl of oil and 227.5 Bcf of natural gas, at March 31, 2017.

Three Months Ended March 31, 2017 as Compared to Three Months Ended March 31, 2016
Oil and natural gas revenues. Our oil and natural gas revenues increase d $70.9 million to $114.8 million, or an increase of 161%, for the three months ended March 31, 2017, as compared to $43.9 million for the three months ended March 31, 2016. Our oil revenues increase d $53.5 million, or 177%, to $83.6 million for the three months ended March 31, 2017, as compared to $30.2 million for the three months ended March 31, 2016. The increase in oil revenues resulted from (i) a higher weighted average oil price realized for the three months ended March 31, 2017 of $50.72 per Bbl, as compared to $28.89 per Bbl realized for the three months ended March 31, 2016 and (ii) the 58% increase in oil production to 1.65 million Bbl of oil for the three months ended March 31, 2017, or about 18,323 Bbl of oil per day, as compared to 1.04 million Bbl of oil, or about 11,473 Bbl of oil per day, for the three months ended March 31, 2016. The increase in oil production is primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin. Our natural gas revenues increase d by $17.4 million, or 127%, to $31.2 million for the three months ended March 31, 2017, as compared to $13.8 million for the three months ended March 31, 2016. The increase in natural gas revenues resulted from (i) a higher weighted average natural gas price realized for the three months ended March 31, 2017 of $3.94 per Mcf, as compared to $2.04 per Mcf realized for the three months ended March 31, 2016 and (ii) the 17% increase in our natural gas production to 7.9 Bcf for the three months ended March 31, 2017, as compared to 6.8 Bcf for the three months ended March 31, 2016. The increase in natural gas production was primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin.

Third-party midstream services revenues. Our third-party midstream services revenues increased to $1.6 million, or an increase of more than three-fold, for the three months ended March 31, 2017, as compared to $0.5 million for the three months ended March 31, 2016. This increase was primarily attributable to a significant increase in natural gas gathering and processing revenues to approximately $1.1 million for the three months ended March 31, 2017, as compared to $0.3 million for the three months ended March 31, 2016, due to increased natural gas production in our Wolf asset area and to our natural gas gathering system and the Black River Processing Plant in the Rustler Breaks asset area being placed into service in the second half of 2016. The remaining increase was primarily attributable to salt water gathering and disposal revenues of $0.3 million for the three months ended March 31, 2017, as compared to $0.1 million for the three months ended March 31, 2016.
Realized loss on derivatives. Our realized net loss on derivatives was $2.2 million for the three months ended March 31, 2017, as compared to a realized net gain of $7.1 million for the three months ended March 31, 2016. We realized a net loss of $1.6 million and $0.6 million from our oil and natural gas derivative contracts, respectively, for the three months ended March 31, 2017, resulting from oil and natural gas prices that were above the ceiling prices of certain of our oil and natural gas costless collar contracts. We realized net gains of $5.5 million and $1.6 million from our oil and natural gas derivative contracts, respectively, for the three months ended March 31, 2016, resulting from oil and natural gas prices being below the floor prices of the majority of our oil and natural gas costless collar contracts. We realized an average loss of approximately $1.70 per Bbl hedged on all of our open oil costless collar contracts during the three months ended March 31, 2017, as compared to an average gain of $11.15 per Bbl hedged for the three months ended March 31, 2016. Our oil volumes hedged for the three months ended March 31, 2017 were also 96% higher as compared to the three months ended March 31, 2016. We realized an average loss of approximately $0.11 per MMBtu hedged on all of our open natural gas costless collar contracts during the three months ended March 31, 2017, as compared to an average gain of approximately $0.58 per MMBtu hedged on all of our open natural gas costless collar contracts for the three months ended March 31, 2016. Our total natural gas volumes hedged for the three months ended March 31, 2017 were also 94% higher than the total natural gas volumes hedged for the three months ended March 31, 2016.
Unrealized gain on derivatives. Our unrealized net gain on derivatives was $20.6 million for the three months ended March 31, 2017, as compared to an unrealized net loss of $6.8 million for the three months ended March 31, 2016. During the three months ended March 31, 2017, the net fair value of our open oil and natural gas derivative contracts changed to a net liability of approximately $4.3 million from a net liability of $25.0 million at December 31, 2016, resulting in an unrealized net gain on derivatives of $20.6 million for the three months ended March 31, 2017. During the three months ended March 31, 2017, the net fair value of our open oil and natural gas derivative contracts increase d by $17.8 million and $2.9 million, respectively, due to the decrease in the underlying oil and natural gas futures prices at March 31, 2017, as compared to December 31, 2016, as well as realized losses from oil and natural gas derivatives contracts settled during the three months ended March 31, 2017.

Three Months Ended March 31, 2017 as Compared to Three Months Ended March 31, 2016
Production taxes, transportation and processing. Our production taxes, transportation and processing expenses increase d by $3.9 million to $11.8 million, or an increase of 49%, for the three months ended March 31, 2017, as compared to $7.9 million for the three months ended March 31, 2016. On a unit-of-production basis, our production taxes, transportation and processing expenses increase d 9% to $3.98 per BOE for the three months ended March 31, 2017, as compared to $3.64 per BOE for the three months ended March 31, 2016. The increase in production taxes, transportation and processing expenses was primarily attributable to the increase in our production taxes of $4.9 million to $7.2 million for the three months ended March 31, 2017, as compared to $2.2 million for the three months ended March 31, 2016, primarily due to the 161% increase in oil and natural gas revenues for the three months ended March 31, 2017, as compared to the three months ended March 31, 2016. In addition to the increase in production taxes attributable to the 161% increase in oil and natural gas revenues, the production tax rates in New Mexico are higher than production tax rates in Texas. As more of our oil and natural gas production becomes attributable to New Mexico, we expect to continue to experience increased production tax expenses. The increased production taxes were partially offset by a decrease in transportation and processing expenses. Transportation and processing expenses decreased to $4.5 million for the three months ended March 31, 2017, as compared to transportation and processing expenses of $5.7 million for the three months ended March 31, 2016. This decrease of $1.2 million was primarily due to the start-up in late August 2016 of the Black River Processing Plant, which processes most of the natural gas produced in our Rustler Breaks asset area in Eddy County, New Mexico.

a unit‑of-production basis, these first quarter 2017 expenses also benefited from significantly higher total oil equivalent production, which increased 37% in the first quarter of 2017, as compared to the first quarter of 2016.
Lease operating. Our lease operating expenses increase d by $1.2 million to $15.8 million, or an increase of 9%, for the three months ended March 31, 2017, as compared to $14.5 million for the three months ended March 31, 2016. Our lease operating expenses per unit of production decrease d 21% to $5.31 per BOE for the three months ended March 31, 2017, as compared to $6.69 per BOE for the three months ended March 31, 2016. Our total oil equivalent production increased 37% to approximately 3.0 million BOE for the three months ended March 31, 2017 from approximately 2.2 million BOE for the three months ended March 31, 2016. The decrease achieved in lease operating expenses on a unit-of-production basis was primarily attributable to several key factors, including (i) decreased field supervisory costs as a number of third-party contractors became full-time employees during the second quarter of 2016, (ii) decreased costs associated with our Eagle Ford operations, including workover, salt water disposal and chemical costs, (iii) additional salt water disposal and gathering capacity added in both the Wolf and Rustler Breaks asset areas and (iv) increased oil equivalent production as compared to the three months ended March 31, 2016. This decrease was partially offset by increased workover expenses in the Wolf asset area during the first quarter of 2017.
Plant and other midstream services operating. Our plant and other midstream services operating expenses increase d by $1.3 million to $2.3 million, an increase of 128%, for the three months ended March 31, 2017, as compared to $1.0 million for the three months ended March 31, 2016. This increase was primarily attributable to the expenses associated with our salt water disposal operations of $1.5 million for the three months ended March 31, 2017, as compared to $0.7 million for the three months ended March 31, 2016, as a result of additional salt water disposal wells operating in the first quarter of 2017, as compared to the first quarter of 2016. The remaining increase was primarily attributable to expenses associated with the Black River Processing Plant that began operating in August 2016.
Depletion, depreciation and amortization. Our depletion, depreciation and amortization expenses increase d by $5.1 million to $34.0 million, or an increase of 18%, for the three months ended March 31, 2017, as compared to $28.9 million for the three months ended March 31, 2016. On a unit-of-production basis, our depletion, depreciation and amortization expenses decrease d 14% to $11.45 per BOE for the three months ended March 31, 2017, as compared to $13.33 per BOE for the three months ended March 31, 2016. The increase in our total depletion, depreciation and amortization expenses resulted primarily from the increase in oil and natural gas production of 37% to 3.0 million BOE for the three months ended March 31, 2017, as compared to 2.2 million BOE for the three months ended March 31, 2016. In addition, depreciation expenses attributable to our midstream segment were approximately $1.2 million for the three months ended March 31, 2017, as compared to $0.5 million for the three months ended March 31, 2016. The decrease in our depletion, depreciation and amortization expenses on a unit-of-production basis was attributable to (i) the impairment charges recorded in 2016, (ii) higher total proved reserves of 117.1 million BOE, or an increase of 30%, at March 31, 2017, as compared to total proved reserves of 90.2 million BOE at March 31, 2016 and (iii) the decreased cost on a unit-of-production basis associated with wells drilled in the Delaware Basin. The increase in total proved oil and natural gas reserves was primarily attributable to the continued delineation and development of our acreage in the Delaware Basin.
Full-cost ceiling impairment. At March 31, 2017, we recorded no impairment charge to the net capitalized costs of our oil and natural gas properties. We recorded an impairment charge of $80.5 million to the net capitalized costs of our oil and natural gas properties for the three months ended March 31, 2016.
General and administrative. Our general and administrative expenses increase d $3.2 million to $16.3 million, an increase of 24%, for the three months ended March 31, 2017, as compared to $13.2 million for the three months ended March 31, 2016. The increase in our general and administrative expenses was primarily attributable to the transaction costs of approximately $3.5 million related to the formation of San Mateo, as well as increased payroll expenses of approximately $2.6 million associated with additional employees joining the Company to support our increased land, geoscience, drilling, completion, production, midstream, accounting and administration functions as a result of the continued growth of the Company. Additionally, non-cash stock-based compensation expense increase d by $1.9 million to $4.2 million for the three months ended March 31, 2017, as compared to $2.2 million for the three months ended March 31, 2016. The increase in our non-cash stock-based compensation was attributable to the increased expense related to the continued vesting of awards granted from 2013 through 2017. These increases were partially offset by the increase in capitalized general and administrative expense of $3.6 million due to our increased delineation and development activities in the Delaware Basin for the three months ended March 31, 2017, as compared to the three months ended March 31, 2016, as well as decreases in consulting and accounting fees of $0.4 million as compared to the three months ended March 31, 2016. Our general and administrative expenses decrease d 9% on a unit-of-production basis to $5.50 per BOE for the three months ended March 31, 2017, as compared to $6.07 per BOE for the three months ended March 31, 2016, primarily due to our increased total oil equivalent production.
Interest expense. For the three months ended March 31, 2017, we incurred total interest expense of approximately $9.7 million. We capitalized approximately $1.2 million of our interest expense on certain qualifying projects for the three months ended March 31, 2017 and expensed the remaining $8.5 million to operations. For the three months ended March 31, 2016, we incurred total interest expense of approximately $7.6 million. We capitalized $0.4 million of our interest expense on certain qualifying projects for the three months ended March 31, 2016 and expensed the remaining $7.2 million to operations. The

Table of Contents
increase in total interest expense of $2.1 million for the three months ended March 31, 2017, as compared to the three months ended March 31, 2016, was attributable to an increase in the average debt outstanding. At March 31, 2017, we had no borrowings outstanding and $0.8 million in letters of credit outstanding under our revolving credit agreement (the “Credit Agreement”) and $575.0 million in outstanding senior notes. At March 31, 2016, we had no borrowings outstanding and $0.6 million in letters of credit outstanding under our Credit Agreement and $400.0 million in outstanding senior notes.
Total income tax benefit. Our deferred tax assets exceeded our deferred tax liabilities at March 31, 2017 due to the deferred tax amounts generated by the full-cost ceiling impairment charges recorded in prior periods. As a result, we established a valuation allowance against the deferred tax assets beginning in the third quarter of 2015. We retained a full valuation allowance at March 31, 2017 due to uncertainties regarding the future realization of our deferred tax assets.
Liquidity and Capital Resources
Our primary use of capital has been, and we expect will continue to be during the remainder of 2017 and for the foreseeable future, for the acquisition, exploration and development of oil and natural gas properties and for midstream investments. Excluding any possible significant acquisitions, we expect to fund our capital expenditure requirements through the remainder of 2017 with a combination of cash on hand (including proceeds we received in connection with the formation of the Joint Venture), operating cash flows and borrowings under our Credit Agreement (assuming availability under our borrowing base). We continually evaluate other capital sources, including borrowings under additional credit arrangements, the sale or joint venture of midstream assets or oil and natural gas producing assets or acreage, particularly in our non-core asset areas, as well as potential issuances of equity, debt or convertible securities, none of which may be available on satisfactory terms or at all. Our future success in growing proved reserves and production will be highly dependent on our ability to access outside sources of capital and to generate operating cash flows.
On February 17, 2017, we announced the formation of San Mateo, a strategic joint venture with Five Point to operate and expand our Delaware Midstream Assets. We received $171.5 million in connection with the formation of the Joint Venture and may earn up to an additional $73.5 million in performance incentives over the next five years. We continue to operate the Delaware Midstream Assets and retain operational control of the Joint Venture. The Company and Five Point own 51% and 49% of the Joint Venture, respectively. San Mateo will continue to provide firm capacity service to us at market rates, while also being a midstream service provider to third parties in and around our Wolf and Rustler Breaks asset areas.
We expect that development of our Delaware Basin assets will be the primary focus of our operations and capital expenditures for the remainder of 2017. We operated four contracted drilling rigs in the Delaware Basin during the first quarter of 2017 and added a fifth drilling rig in the Delaware Basin in late April 2017. Our 2017 estimated capital expenditure budget consists of $400 to $420 million for drilling, completions, facilities and infrastructure and $56 to $64 million for midstream capital expenditures, which represents our 51% share of an estimated 2017 capital expenditure budget of $110 to $125 million for San Mateo. Our 2017 estimated capital expenditures will be allocated to the further delineation and development of our growing leasehold position and midstream assets in the Delaware Basin, with the exception of a total of approximately $34 to $36 million allocated to a five-well operated program in the Eagle Ford shale and limited operations in the Eagle Ford and Haynesville shales to maintain and extend leases and to participate in certain non-operated well opportunities. Our 2017 Delaware Basin drilling program will focus on the continued development of the Wolf and Rustler Breaks asset areas and the further delineation and development of the Jackson Trust, Ranger/Arrowhead and Twin Lakes asset areas, although we do anticipate continuing to delineate previously untested zones in the Wolf and Rustler Breaks asset areas during 2017.
We intend to continue acquiring acreage and mineral interests, principally in the Delaware Basin, during the remainder of 2017. These expenditures are opportunity-specific and per-acre prices can vary significantly based on the opportunity. As a result, it is difficult to estimate these 2017 capital expenditures with any degree of certainty; therefore, we have not provided estimated capital expenditures related to acreage and mineral acquisitions for the remainder of 2017.
From January 1 through May 3, 2017, we acquired approximately 15,900 gross (9,500 net) acres and approximately 1,000 BOE per day of related production from various lessors, mineral owners and other operators, mostly in and around our existing acreage in the Delaware Basin. Some of this acreage and a portion of the production included properties identified at the time of our December 2016 senior notes and common stock offerings. These transactions were pending at the time of those offerings and closed subsequent to December 31, 2016. Our Permian Basin acreage position at May 3, 2017 was 178,600 gross (102,300 net) acres, almost all of which was located in the Delaware Basin. We have incurred capital expenditures of approximately $121 million since January 1, 2017 to acquire the acreage and related production.
At March 31, 2017, we had cash totaling approximately $209.7 million and restricted cash totaling approximately $14.6 million. Restricted cash represents cash held by our less-than-wholly-owned subsidiaries. By contractual agreement, the cash in the accounts held by our less-than-wholly-owned subsidiaries is not to be commingled with other Company cash and is to be used only to fund the capital expenditures and operations of these less-than-wholly-owned subsidiaries.

Table of Contents
Our 2017 capital expenditures may be adjusted as business conditions warrant and the amount, timing and allocation of such expenditures is largely discretionary and within our control. The aggregate amount of capital we will expend may fluctuate materially based on market conditions, the actual costs to drill, complete and place on production operated or non-operated wells, our drilling results, the actual costs and scope of our midstream activities, including the expansion of the Black River Processing Plant, the ability of our Joint Venture partner to meet its capital obligations, other opportunities that may become available to us and our ability to obtain capital. When oil or natural gas prices decline, or costs increase significantly, we have the flexibility to defer a significant portion of our capital expenditures until later periods to conserve cash or to focus on projects that we believe have the highest expected returns and potential to generate near-term cash flows. We routinely monitor and adjust our capital expenditures in response to changes in prices, availability of financing, drilling, completion and acquisition costs, industry conditions, the timing of regulatory approvals, the availability of rigs, success or lack of success in our exploration and development activities, contractual obligations, drilling plans for properties we do not operate and other factors both within and outside our control.
Exploration and development activities are subject to a number of risks and uncertainties, which could cause these activities to be less successful than we anticipate. A significant portion of our anticipated cash flows from operations for the remainder of 2017 is expected to come from producing wells and development activities on currently proved properties in the Wolfcamp and Bone Spring plays in the Delaware Basin, the Eagle Ford shale in South Texas and the Haynesville shale in Louisiana. Our existing wells may not produce at the levels we are forecasting and our exploration and development activities in these areas may not be as successful as we anticipate. Additionally, our anticipated cash flows from operations are based upon current expectations of oil and natural gas prices for the remainder of 2017 and the hedges we currently have in place. We use commodity derivative financial instruments at times to mitigate our exposure to fluctuations in oil, natural gas and natural gas liquids prices and to partially offset reductions in our cash flows from operations resulting from declines in commodity prices. As of May 3, 2017, we had approximately 65% of our anticipated oil production and approximately 70% of our anticipated natural gas production hedged for the remainder of 2017. See Note 8 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for a summary of our open derivative financial instruments at March 31, 2017.
Our unaudited cash flows for the three months ended March 31, 2017 and 2016 are presented below:

| Three Months Ended March 31,

__________________

(1) | Adjusted EBITDA is a non-GAAP financial measure. For a definition of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to our net income (loss) and net cash provided by operating activities, see “— Non-GAAP Financial Measures” below.

Cash Flows Provided by Operating Activities
Net cash provided by operating activities increase d $43.0 million to $61.3 million for the three months ended March 31, 2017, as compared to net cash provided by operating activities of $18.4 million for the three months ended March 31, 2016. Excluding changes in operating assets and liabilities, net cash provided by operating activities increase d to $63.8 million for the three months ended March 31, 2017 from $10.3 million for the three months ended March 31, 2016. This increase was primarily attributable to higher oil and natural gas production and higher commodity prices and was partially offset by the decrease in our realized gains on derivatives. Changes in our operating assets and liabilities between the three months ended March 31, 2016 and the three months ended March 31, 2017 resulted in a net decrease of approximately $10.5 million in net cash provided by operating activities for the three months ended March 31, 2017, as compared to the three months ended March 31, 2016.
Our operating cash flows are sensitive to a number of variables, including changes in our production and volatility of oil and natural gas prices between reporting periods. Regional and worldwide economic activity, the actions of OPEC, weather, infrastructure capacity to reach markets and other variable factors significantly impact the prices of oil and natural gas. These factors are beyond our control and are difficult to predict. We use commodity derivative financial instruments to mitigate our exposure to fluctuations in oil, natural gas and natural gas liquids prices. In addition, we attempt to avoid long-term service agreements where possible in order to minimize ongoing future commitments.

Cash Flows Used in Investing Activities
Net cash used in investing activities increase d by $180.4 million to $238.3 million for the three months ended March 31, 2017 from $57.9 million for the three months ended March 31, 2016. This increase in net cash used in investing activities is primarily due to an increase of $130.1 million in oil and natural gas properties capital expenditures for the three months ended March 31, 2017, as compared to the three months ended March 31, 2016. Cash used for oil and natural gas properties capital expenditures for the three months ended March 31, 2017 was primarily attributable to the acquisition of additional leasehold and mineral interests and our operated drilling and completion activities in the Delaware Basin. A small portion of our capital expenditures for the three months ended March 31, 2017 was directed to our participation in non-operated wells. Additionally, there was an increase in cash outflows related to restricted cash of approximately $57.2 million between the two periods. These increases were partially offset by a decrease in cash used for other property and equipment of approximately $6.5 million.
Cash Flows Provided by Financing Activities
Net cash provided by financing activities increase d by $32.7 million to $173.8 million for the three months ended March 31, 2017 from $141.2 million for the three months ended March 31, 2016. The net cash provided by financing activities for the three months ended March 31, 2017 was primarily attributable to the contributions related to the formation of the Joint Venture of $171.5 million. The net cash provided by financing activities for the three months ended March 31, 2016 was primarily attributable to the net proceeds from our March 2016 equity offering of $142.4 million ($141.7 million including cost to issue equity).
See Note 5 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for a summary of our debt, including our Credit Agreement and the senior notes.
Non-GAAP Financial Measures
We define Adjusted EBITDA as earnings before interest expense, income taxes, depletion, depreciation and amortization, accretion of asset retirement obligations, property impairments, unrealized derivative gains and losses, certain other non-cash items and non-cash stock-based compensation expense, and net gain or loss on asset sales and inventory impairment. Adjusted EBITDA is not a measure of net income (loss) or cash flows as determined by GAAP. Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies.
Management believes Adjusted EBITDA is necessary because it allows us to evaluate our operating performance and compare the results of operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from net income (loss) in calculating Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which certain assets were acquired.
Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income or cash flows from operating activities as determined in accordance with GAAP or as a primary indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components of understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure. Our Adjusted EBITDA may not be comparable to similarly titled measures of another company because all companies may not calculate Adjusted EBITDA in the same manner.

The net income attributable to Matador Resources Company shareholders increased by $151.6 million to $44.0 million for the three months ended March 31, 2017, as compared to a net loss attributable to Matador Resources Company shareholders of $107.7 million for the three months ended March 31, 2016. This increase in net income attributable to Matador Resources Company shareholders for the three months ended March 31, 2017 as compared to the three months ended March 31, 2016 is primarily attributable to (i) the decrease of $80.5 million in the full-cost ceiling impairment and (ii) the increase in oil and natural gas revenues of $70.9 million.
Our Adjusted EBITDA attributable to Matador Resources Company shareholders increased by $52.8 million to $70.0 million for the three months ended March 31, 2017, as compared to $17.2 million for the three months ended March 31, 2016. This increase in our Adjusted EBITDA attributable to Matador Resources Company shareholders is primarily attributable to higher oil and natural gas production and higher commodity prices, which was partially offset by the decrease in the realized gain on derivatives for the three months ended March 31, 2017, as compared to the three months ended March 31, 2016.

General Outlook and Trends
For the three months ended March 31, 2017, oil prices averaged $51.78 per Bbl, ranging from a high of $54.45 per Bbl in late February to a low of $47.34 per Bbl in late March, based upon the NYMEX West Texas Intermediate oil futures contract price for the earliest delivery date. We realized an average oil price of $50.72 per Bbl ($49.73 per Bbl including realized losses from oil derivatives) for our oil production for the three months ended March 31, 2017, as compared to $28.89 per Bbl ($34.12 per Bbl including realized gains from oil derivatives) for the three months ended March 31, 2016. At May 3, 2017, the NYMEX West Texas Intermediate oil futures contract for the earliest delivery date had declined slightly from the weighted average price for the first quarter of 2017, settling at $47.82 per Bbl, which was an increase as compared to $43.65 per Bbl at May 3, 2016.
For the three months ended March 31, 2017, natural gas prices averaged $3.06 per MMBtu, ranging from a high of approximately $3.42 per MMBtu in mid-January to a low of approximately $2.56 per MMBtu in late February, based upon the NYMEX Henry Hub natural gas futures contract price for the earliest delivery date. We realized a weighted average natural gas price of $3.94 per Mcf ($3.86 per Mcf including realized losses from natural gas derivatives) for our natural gas production (including revenues attributable to natural gas liquids) for the three months ended March 31, 2017, as compared to $2.04 per Mcf ($2.27 per Mcf including realized gains from natural gas derivatives) for the three months ended March 31, 2016. At May 3, 2017, the NYMEX Henry Hub natural gas futures contract for the earliest delivery date had increased from the weighted average price for the first quarter of 2017, settling at $3.23 per MMBtu, which was a significant increase as compared to $2.09 per MMBtu at May 3, 2016.
The prices we receive for oil, natural gas and natural gas liquids heavily influence our revenue, profitability, cash flow available for capital expenditures, access to capital and future rate of growth. Oil, natural gas and natural gas liquids are commodities, and therefore, their prices are subject to wide fluctuations in response to relatively minor changes in supply and demand. Historically, the markets for oil, natural gas and natural gas liquids have been volatile and these markets will likely continue to be volatile in the future. Declines in oil, natural gas or natural gas liquids prices not only reduce our revenues, but could also reduce the amount of oil, natural gas and natural gas liquids we can produce economically. We are uncertain if oil and natural gas prices may rise from their current levels, and in fact, oil and natural gas prices may decrease again in future periods.
From time to time, we use derivative financial instruments to mitigate our exposure to commodity price risk associated with oil, natural gas and natural gas liquids prices. Even so, decisions as to whether, at what price and what production volumes to hedge are difficult and depend on market conditions and our forecast of future production and oil, natural gas and natural gas liquids prices, and we may not always employ the optimal hedging strategy. This, in turn, may affect the liquidity that can be accessed through the borrowing base under our Credit Agreement and through the capital markets. We expect our realized gains from derivatives, if any, to be less for the remainder of 2017, as compared to comparable periods in 2016, especially from our oil derivative contracts, as a result of higher oil prices anticipated in 2017 as compared to 2016.
Coinciding with the recent improvements in oil and natural gas prices since the latter part of 2016, we have begun to experience price increases from our service providers for some of the products and services we use in our drilling, completion and production operations. If oil and natural gas prices remain at their current levels for a longer period of time or should they increase further, we would anticipate additional price increases for drilling, completion and production products and services, although we can provide no estimates as to the eventual magnitude of these increases.
Like other oil and natural gas producing companies, our properties are subject to natural production declines. By their nature, our oil and natural gas wells will experience rapid initial production declines. We attempt to overcome these production declines by drilling to develop and identify additional reserves, by exploring for new sources of reserves and, at times, by acquisitions. During times of severe oil, natural gas and natural gas liquids price declines, however, drilling additional oil or natural gas wells may not be economical, and we may find it necessary to reduce capital expenditures and curtail drilling operations in order to preserve liquidity. A material reduction in capital expenditures and drilling activities could materially impact our production volumes, revenues, reserves, cash flows and our availability under our Credit Agreement.
We strive to focus our efforts on increasing oil and natural gas reserves and production while controlling costs at a level that is appropriate for long-term operations. Our ability to find and develop sufficient quantities of oil and natural gas reserves at economical costs is critical to our long-term success. Future finding and development costs are subject to changes in the costs of acquiring, drilling and completing our prospects.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Except as set forth below, there have been no material changes to the sources and effects of our market risk since December 31, 2016, which are disclosed in Part II, Item 7A of the Annual Report and incorporated herein by reference.
Commodity price exposure. We are exposed to market risk as the prices of oil, natural gas and natural gas liquids fluctuate as a result of changes in supply and demand and other factors. To partially reduce price risk caused by these market
35

Table of Contents
fluctuations, we have entered into derivative financial instruments in the past and expect to enter into derivative financial instruments in the future to cover a significant portion of our anticipated future production.
We typically use costless (or zero-cost) collars and/or swap contracts to manage risks related to changes in oil, natural gas and natural gas liquids prices. Costless collars provide us with downside price protection through the purchase of a put option which is financed through the sale of a call option. Because the call option proceeds are used to offset the cost of the put option, these arrangements are initially “costless” to us. In the case of a costless collar, the put option and the call option have different fixed price components. In a swap contract, a floating price is exchanged for a fixed price over a specified period, providing downside price protection.
We record all derivative financial instruments at fair value. The fair value of our derivative financial instruments is determined using purchase and sale information available for similarly traded securities. At March 31, 2017, Comerica Bank, The Bank of Nova Scotia, BMO Harris Financing (Bank of Montreal) and SunTrust Bank (or affiliates thereof) were the counterparties for all of our derivative instruments. We have considered the credit standing of the counterparties in determining the fair value of our derivative financial instruments. See Note 8 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for a summary of our open derivative financial instruments at March 31, 2017. Such information is incorporated herein by reference.
