TABLE OF CONTENTS

GLOSSARY OF OIL AND NATURAL GAS TERMS

The following is a glossary of certain oil and gas terms that are used in this Quarterly Report on Form 10-Q (this “report”):



Basin	A large depression on the earth’s surface in which sediments accumulate.
Bbl	Stock tank barrel, or 42 U.S. gallons liquid volume, used in this report in reference to crude oil or other liquid hydrocarbons.
~~Bbls/d~~	~~Bbls per day.~~
BOE	Barrels of oil equivalent, with six thousand cubic feet of natural gas being equivalent to one barrel of oil.
BOE/d	BOE per day.
British Thermal Unit or Btu	The quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
Completion	The process of treating a drilled well followed by the installation of permanent equipment for the production of natural gas or oil, or in the case of a dry hole, the reporting of abandonment to the appropriate agency.
~~Condensate~~	~~Liquid hydrocarbons associated with the production of a primarily natural gas reserve.~~
Crude oil	Liquid hydrocarbons retrieved from geological structures underground to be refined into fuel sources.
Finding and development costs	Capital costs incurred in the acquisition, exploitation and exploration of proved oil and natural gas reserves divided by proved reserve additions and revisions to proved reserves.
Gross acres or gross wells	The total acres or wells, as the case may be, in which a working interest is owned.
Horizontal drilling	A drilling technique used in certain formations where a well is drilled vertically to a certain depth and then drilled at a right angle with a specified interval.
Horizontal wells	Wells drilled directionally horizontal to allow for development of structures not reachable through traditional vertical drilling mechanisms.
Mcf	Thousand cubic feet of natural gas.
Mcf/d	Mcf per day.
Mineral interests	The interests in ownership of the resource and mineral rights, giving an owner the right to profit from the extracted resources.
MMBtu	Million British Thermal Units.
Net acres or net wells	The sum of the fractional working interest owned in gross acres.
Oil and natural gas properties	Tracts of land consisting of properties to be developed for oil and natural gas resource extraction.
Play	A set of discovered or prospective oil and/or natural gas accumulations sharing similar geologic, geographic and temporal properties, such as source rock, reservoir structure, timing, trapping mechanism and hydrocarbon type.
Plugging and abandonment	Refers to the sealing off of fluids in the strata penetrated by a well so that the fluids from one stratum will not escape into another or to the surface. Regulations of all states require plugging of abandoned wells.
Prospect	A specific geographic area which, based on supporting geological, geophysical or other data and also preliminary economic analysis using reasonably anticipated prices and costs, is deemed to have potential for the discovery of commercial hydrocarbons.
Proved reserves	The estimated quantities of oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be commercially recoverable in future years from known reservoirs under existing economic and operating conditions.
Reserves	~~Reserves are~~The estimated remaining quantities of oil and natural gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and natural gas or related substances to the market and all permits and financing required to implement the project. Reserves ~~should~~are not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations).



Reservoir	A porous and permeable underground formation containing a natural accumulation of producible natural gas and/or oil that is confined by impermeable rock or water barriers and is separate from other reservoirs.



Royalty interest	An interest that gives an owner the right to receive a portion of the resources or revenues without having to carry any costs of development.
Spacing	The distance between wells producing from the same reservoir. Spacing is often expressed in terms of acres (e.g., 40-acre spacing) and is often established by regulatory agencies.
Working interest	An operating interest that gives the owner the right to drill, produce and conduct operating activities on the property and receive a share of production and requires the owner to pay a share of the costs of drilling and production operations.

In particular, the factors discussed in this report and detailed under Part II, Item 1A. Risk Factors in this report and our Annual Report on Form 10–K for the year ended December 31, ~~2015~~2016 could affect our actual results and cause our actual results to differ materially from expectations, estimates or assumptions expressed, forecasted or implied in such forward-looking statements.

1. DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

Organization and Description of the Business

Diamondback Energy, Inc. (“Diamondback” or the “Company”), together with its subsidiaries, is an independent oil and gas company currently focused on the acquisition, development, exploration and exploitation of unconventional, onshore oil and natural gas reserves in the Permian Basin in West Texas. Diamondback was incorporated in Delaware on December 30, 2011.

The wholly-owned subsidiaries of Diamondback, as of March 31, ~~2016,~~2017, include Diamondback E&P LLC, a Delaware limited liability company, Diamondback O&G LLC, a Delaware limited liability company, Viper Energy Partners GP LLC, a Delaware limited liability company, and Rattler Midstream LLC (formerly known as White Fang Energy ~~LLC,~~LLC), a Delaware limited liability company. The consolidated subsidiaries include the wholly-owned subsidiaries as well as Viper Energy Partners LP, a Delaware limited partnership (the “Partnership”), and the Partnership’s wholly-owned subsidiary Viper Energy Partners LLC, a Delaware limited liability company.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries after all significant intercompany balances and transactions have been eliminated upon consolidation.

The Partnership is consolidated in the financial statements of the Company. As of March 31, ~~2016,~~2017, the Company owned approximately ~~88%~~74% of the common units of the Partnership and the Company’s wholly-owned subsidiary, Viper Energy Partners GP LLC, is the General Partner of the Partnership.

These financial statements have been prepared by the Company without audit, pursuant to the rules and regulations of the SEC. They reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for interim periods, on a basis consistent with the annual audited financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations, although the Company believes the disclosures are adequate to make the information presented not misleading. This Quarterly Report on Form 10–Q should be read in conjunction with the Company’s most recent Annual Report on Form 10–K for the fiscal year ended December 31, ~~2015,~~2016, which contains a summary of the Company’s significant accounting policies and other disclosures.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

Certain amounts included in or affecting the Company’s consolidated financial statements and related disclosures must be estimated by management, requiring certain assumptions to be made with respect to values or conditions that cannot be known with certainty at the time the consolidated financial statements are prepared. These estimates and assumptions affect the amounts the Company reports for assets and liabilities and the Company’s disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates.

The Company evaluates these estimates on an ongoing basis, using historical experience, consultation with experts and other methods the Company considers reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from the Company’s estimates. Any effects on the Company’s business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Significant items subject to such estimates and assumptions include estimates of proved oil and natural gas reserves and related present value estimates of future net cash flows therefrom, the carrying value of oil and natural gas properties, asset retirement obligations, the fair value determination of acquired assets and liabilities, equity-based compensation, fair value estimates of commodity derivatives and estimates of income taxes.

New Accounting Pronouncements

In ~~April~~May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers”. This update supersedes most of the existing revenue recognition requirements in GAAP and requires (i) an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services and (ii) requires expanded disclosures regarding the nature, amount, timing and certainty of revenue and cash flows from contracts with customers. The standard will be effective for annual and interim reporting periods beginning after December 15, 2017, with early application permitted for annual reporting period beginning after December 31, 2016. The standard allows for either full retrospective adoption, meaning the standard is applied to all periods presented in the financial statements, or modified retrospective adoption, meaning the standard is applied only to the most current period presented. The Company is currently evaluating the impact of this standard; however, it does not believe this standard will have a material impact on the Company’s consolidated financial statements.

In July 2015, the Financial Accounting Standards Board issued Accounting Standards Update ~~2015-03, “Interest–Imputation of Interest”~~2015-11, “Inventory”. This update ~~requires~~applies to all inventory that ~~debt issuance costs related to a recognized debt liability (except costs associated with revolving debt arrangements) be presented in~~is not measured using last-in, first-out or the ~~balance sheet as a direct deduction from that debt liability, consistent with~~retail inventory method. Under this update, an entity should measure inventory at the ~~presentation~~lower of ~~a debt discount, to simplify the presentation of debt issuance costs.~~cost and net realizable value. This ~~update is~~standard was effective for financial statements issued for fiscal years beginning after December 15, ~~2015, and~~2016, including interim periods within those fiscal years. ~~Early application~~This standard should be applied prospectively with early adoption permitted as of the beginning of an interim or annual reporting period. The Company adopted this standard prospectively effective January 1, 2017. The adoption of this standard had no impact on the Company’s financial position, results of operations or liquidity because the Company currently measures its inventory at the lower of cost or net realizable value.

In November 2015, the Financial Accounting Standards Board issued Accounting Standards Update 2015-17, “Income Taxes”. This update requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The standard was ~~permitted~~effective for financial statements ~~that have not previously been issued.~~issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. This standard may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company ~~retrospectively~~ adopted this ~~new~~ standard prospectively effective January 1, ~~2016. Adoption of this standard only affects the presentation of the Company’s consolidated balance sheets~~2017. The Company will present deferred tax liabilities and ~~does not have a material impact on its consolidated financial statements.~~assets as noncurrent.

In January 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-01, “Financial Instruments–Overall”. This update applies to any entity that ~~hold~~holds financial assets or ~~owe~~owes financial liabilities. This update requires equity investments (except for those accounted for under the equity method or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. This update will be effective for public entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. Entities should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. While this update will not have a direct impact on the Company, the Partnership will be required to mark its cost method investment to fair value with the adoption of this update.

In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-02, “Leases”. This update applies to any entity that enters into a lease, with some specified scope exemptions. Under this update, a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. While there were no major changes to the lessor accounting, changes were made to align key aspects with the revenue recognition guidance. This update will be effective for public entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. Entities will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company believes the primary impact of adopting this standard will be the recognition of assets and liabilities on the balance sheet for current operating leases. The Company is ~~currently~~still evaluating the impact ~~that the adoption~~ of this ~~update will have on the Company’s financial position, results of operations and liquidity.~~standard.

In March 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-08, “Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”. Under this update, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This update will be effective for annual and interim reporting periods beginning after December 15,

2017, with early application not permitted. This update allows for either full retrospective adoption, meaning this update is applied to all periods presented in the financial statements, or modified retrospective adoption, meaning this update is applied only to the most current period presented. The Company is currently evaluating the impact, if any, that the adoption of this update will have on the Company’s financial position, results of operations and liquidity.

In March 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-09, "Compensation - Stock Compensation". This update applies to all entities that issue ~~share-based~~equity-based payment awards to their employees. Under this update, there were several areas that were simplified including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This update ~~will be~~was effective for financial statements issued for fiscal years beginning after December 15, 2016, including interim periods within those fiscal ~~years with early adoption permitted.~~years. The Company ~~is currently evaluating~~prospectively adopted this standard effective January 1, 2017. The Company revised its calculation of diluted earnings per share to exclude the ~~impact~~amount of excess tax benefits that would be recognized in additional paid-in capital. The Company also adopted a policy to account for forfeitures as they occur.

In April 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-10, “Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing”. This update clarifies two principles of Accounting Standards Codification Topic 606: identifying performance obligations and the licensing implementation guidance. This standard has the same effective date as Accounting Standards Update 2016-08, the revenue recognition standard discussed above. The adoption of this ~~update will~~standard is not expected to have a material impact on the Company's financial position, results of operations and liquidity.

In May 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-12, “Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients”. This update applies only to the following areas from Accounting Standards Codification Topic 606: assessing the collectability criterion and accounting for contracts that do not meet the criteria for step 1, presentation of sales taxes and other similar taxes collected from customers, non-cash consideration, contract modification at transition, completed contracts at transition and technical correction. This standard has the same effective date as Accounting Standards Update 2016-08, the revenue recognition standard discussed above. The adoption of this standard is not expected to have a material impact on the Company's financial position, results of operations and liquidity.

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, “Financial Instruments - Credit Losses”. This update affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. This update will be effective for financial statements issued for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. This update will be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company does not believe the adoption of this standard will have a material impact on the Company’s consolidated financial statements since the Company does not have a history of credit losses.

In August 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-15, “Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments”. This update apples to all entities that are required to present a statement of cash flows. This update provides guidance on eight specific cash flow issues: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions and separately identifiable cash flows and application of the predominance principle. This update will be effective for financial statements issued for fiscal years beginning after December 31, 2017, including interim periods within those fiscal years with early adoption permitted. This update should be applied using the retrospective transition method. Adoption of this standard will only affect the presentation of the Company’s cash flows and will not have a material impact on the Company’s consolidated financial statements.

In January 2017, the Financial Accounting Standards Board issued Accounting Standards Update 2017-01, “Business Combinations - Clarifying the Definition of a Business”. This update apples to all entities that must determine

Notes to Consolidated Financial Statements-(Continued)

(Unaudited)

whether they acquired or sold a business. This update provides a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This update will be effective for financial statements issued for fiscal years beginning after December 31, 2017, including interim periods within those fiscal years. This update should be applied prospectively on or after the effective date. This update is not expected to have a material impact the Company’s financial statements or results of operations. The adoption of this update will change the process that the Company uses to evaluate whether the Company has acquired a business or an asset. This update will be applied prospectively and will not have an effect on prior acquisitions.

3. ACQUISITIONS

On February 28, 2017, the Company completed its acquisition of certain oil and natural gas properties, midstream assets and other related assets in the Delaware Basin for an aggregate purchase price consisting of $1.74 billion in cash and 7.69 million shares of the Company’s common stock, of which approximately 1.15 million shares were placed in an indemnity escrow. This transaction includes the acquisition of (i) approximately 100,306 gross (80,339 net) acres primarily in Pecos and Reeves counties for approximately $2.5 billion and (ii) midstream assets for approximately $47.6 million. The Company used the net proceeds from the December 2016 equity offering, net proceeds from the December 2016 debt offering, cash on hand and other financing sources to fund the cash portion of the purchase price for this acquisition.

The Company is in the process of identifying and determining the fair values of the assets and liabilities assumed, and as a result, the estimates for fair value at March 31, 2017 are subject to change. The following represents the preliminary estimated fair value of the assets and liabilities assumed on the acquisition date. The aggregate consideration transferred was $2.6 billion, subject to post-closing adjustments, resulting in no goodwill or bargain purchase gain.

a fully-consolidated subsidiary of Diamondback, serves as the general partner of, and holds a non-economic general partner interest in, the Partnership. As of March 31, ~~2016,~~2017, the Company owned approximately ~~88%~~74% of the common units of the Partnership.

Partnership Agreement

In connection with the closing of the Viper Offering, the General Partner and Diamondback entered into the first amended and restated agreement of limited partnership, dated June 23, 2014 (the “Partnership Agreement”). The Partnership Agreement requires the Partnership to reimburse the General Partner for all direct and indirect expenses incurred or paid on the Partnership’s behalf and all other expenses allocable to the Partnership or otherwise incurred by the General Partner in connection with operating the Partnership’s business. The Partnership Agreement does not set a limit on the amount of expenses for which the General Partner and its affiliates may be reimbursed. These expenses include salary, bonus, incentive compensation and other amounts paid to persons who perform services for the Partnership or on its behalf and expenses allocated to the General Partner by its affiliates. The General Partner is entitled to determine the expenses that are allocable to the Partnership.

Tax Sharing

In connection with the closing of the Viper Offering, the Partnership entered into a tax sharing agreement with Diamondback, dated June 23, 2014, pursuant to which the Partnership agreed to reimburse Diamondback for its share of state and local income and other taxes for which the Partnership’s results are included in a combined or consolidated tax return filed by Diamondback with respect to taxable periods including or beginning on June 23, 2014. The amount of any such reimbursement is limited to the tax the Partnership would have paid had it not been included in a combined group with Diamondback. Diamondback may use its tax attributes to cause its combined or consolidated group, of which the Partnership may be a member for this purpose, to owe less or no tax. In such a situation, the Partnership agreed to reimburse Diamondback for the tax the Partnership would have owed had the tax attributes not been available or used for the Partnership’s benefit, even though Diamondback had no cash tax expense for that period.

The Company uses the full cost method of accounting for its oil and natural gas properties. Under this method, all acquisition, exploration and development costs, including certain internal costs, are capitalized and amortized on a composite unit of production method based on proved oil, natural gas liquids and natural gas reserves. Internal costs capitalized to the full cost pool represent management’s estimate of costs incurred directly related to exploration and development activities such as geological and other administrative costs associated with overseeing the exploration and development activities. Costs, including related employee costs, associated with production and operation of the properties are charged to expense as incurred. All other internal costs not directly associated with exploration and development activities ~~were~~are charged to expense as they ~~were~~are incurred. Capitalized internal costs were approximately ~~$5.0~~$5.1 million and ~~$4.7~~$5.0 million for the three months ended March 31, ~~2016~~2017 and ~~2015,~~2016, respectively. Costs associated with unevaluated properties are excluded from the full cost pool until the Company has made a determination as to the existence of proved reserves. The inclusion of the Company’s unevaluated costs into the amortization base is expected to be completed within three to five years. Acquisition costs not currently being amortized are primarily related to unproved acreage that the Company plans to prove up through drilling. The Company has no plans to let any acreage expire. Sales of oil and natural gas properties, whether or not being amortized currently, are accounted for as adjustments of capitalized costs, with no gain or loss recognized, unless such adjustments would significantly alter the relationship between capitalized costs and proved reserves of oil, natural gas liquids and natural gas.

Under this method of accounting, the Company is required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value of the proved oil and gas properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes, or the cost center ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted at 10% per annum, from proved reserves, based on the trailing 12-month unweighted average of the first-day-of-the-month price, adjusted for any contract provisions or financial derivatives, if any, that hedge the Company’s oil and natural gas revenue, and excluding the estimated abandonment costs for properties with asset retirement obligations recorded on the balance sheet, (b) the cost of properties not being amortized, if any, and (c) the lower of cost or market value of unproved properties included in the cost being amortized, including related deferred taxes for differences between the book and tax basis of the oil and natural gas properties. If the net book value, including related deferred taxes, exceeds the ceiling, an impairment or non-cash writedown is required.

As a result of the decline in prices, ~~during the three months ended March 31, 2016,~~ the Company recorded a non-cash ~~ceiling test impairments~~impairment for the three months ended March 31, 2016 of $30.8 million, which is included in

The Company’s asset retirement obligations primarily relate to the future plugging and abandonment of wells and related facilities. The Company estimates the future plugging and abandonment costs of wells, the ultimate productive life of the properties, a risk-adjusted discount rate and an inflation factor in order to determine the current present value of this obligation. To the extent future revisions to these assumptions impact the present value of the existing asset retirement obligation liability, a corresponding adjustment is made to the oil and natural gas property balance.

On April 26, 2017, the Company filed with the SEC its Registration Statement on Form S-4 relating to the exchange offers of the 2024 Senior Notes and the 2025 Senior Notes for substantially identical debt securities registered under the Securities Act.

The Company’s Credit Facility

On June 9, 2014, Diamondback O&G LLC, as borrower, entered into a first amendment and on November 13, 2014, Diamondback O&G LLC entered into a second amendment to the second amended and restated credit agreement, dated November 1, 2013 (the “credit agreement”). The first amendment modified certain provisions of the credit agreement to, among other things, allow one or more of the Company’s subsidiaries to be designated as “Unrestricted Subsidiaries” that are not subject to certain restrictions contained in the credit agreement. In connection with the Viper Offering, the Partnership, the General Partner and Viper Energy Partners LLC were designated as unrestricted subsidiaries under the credit agreement. As of March 31, ~~2016,~~2017, the credit agreement was guaranteed by Diamondback, Diamondback E&P LLC and ~~White Fang Energy~~Rattler Midstream LLC and will also be guaranteed by any future restricted subsidiaries of Diamondback. The credit agreement is also secured by substantially all of the assets of Diamondback O&G LLC, the Company and the other guarantors.

The second amendment increased the maximum amount of the credit facility to $2.0 billion, modified the dates and deadlines of the credit agreement relating to the scheduled borrowing base redeterminations based on the Company’s oil and natural gas reserves and other factors and added new provisions that allow the Company to elect a commitment amount that is less than its borrowing base as determined by the lenders. The borrowing base is scheduled to be re-determined semi-annually with effective dates of May 1st and November 1st. In addition, the Company may request up to three additional redeterminations of the borrowing base during any 12-month period. As of March 31, ~~2016,~~2017, the borrowing base was ~~$750.0 million,~~set at $1.0 billion, of which the Company had elected a commitment amount of $500.0 million, and the Company had no outstanding borrowings.

The outstanding borrowings under the credit agreement bear interest at a rate elected by the Company that is equal to an alternative base rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.5% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable margin. The applicable margin ranges from 0.50% to 1.50% in the case of the alternative base rate and from 1.50% to 2.50% in the case of LIBOR, in each case depending on the amount of the loan outstanding in relation to the borrowing base. The Company is obligated to pay a quarterly commitment fee ranging from 0.375% to 0.500% per year on the unused portion of the borrowing base, which fee is also dependent on the amount of the loan outstanding in relation to the borrowing base. Loan principal may be optionally repaid from time to time without premium or penalty (other than customary LIBOR breakage), and is required to be repaid (a) to the extent that the loan amount exceeds the borrowing base, whether due to a borrowing base redetermination or otherwise (in some cases subject to a cure period), (b) in an amount equal to the net cash proceeds from the sale of property when a borrowing base deficiency or event of default exists under the credit agreement and (c) at the maturity date of November 1, 2018.

The credit agreement contains various affirmative, negative and financial maintenance covenants. These covenants, among other things, limit additional indebtedness, additional liens, sales of assets, mergers and consolidations, dividends and distributions, transactions with affiliates and entering into certain swap agreements and require the maintenance of the financial ratios described below.



Financial Covenant		Required Ratio
Ratio of total debt to EBITDAX		Not greater than 4.0 to 1.0
Ratio of current assets to liabilities, as defined in the credit agreement		Not less than 1.0 to 1.0

The covenant prohibiting additional indebtedness, as amended in December 2016, allows for the issuance of unsecured debt of up to ~~$750.0 million~~$1.0 billion in the form of senior or senior subordinated notes and, in connection with any such issuance, the reduction of the borrowing base by 25% of the stated principal amount of each such issuance. A borrowing base reduction in connection with such issuance may require a portion of the outstanding principal of the loan to be repaid. As of March 31, ~~2016,~~2017, the Company had ~~$450.0 million~~$1.0 billion in aggregate principal amount of senior unsecured notes outstanding.

As of March 31, ~~2016~~2017 and December 31, ~~2015,~~2016, the Company was in compliance with all financial covenants under its revolving credit facility, as then in effect. The lenders may accelerate all of the indebtedness under the

The borrowing base is scheduled to be re-determined semi-annually with effective dates of April 1st and October 1st. In addition, the Partnership may request up to three additional redeterminations of the borrowing base during any 12-month period. The credit agreement was further amended on May 22, 2015 to, among other things, increase the borrowing base from $110.0 million to $175.0 million and to provide for certain restrictions on purchasing margin stock. On November 13, 2015,As of March 31, 2017, the borrowing base was ~~increased from $175.0~~set at $275.0 million ~~to $200.0 million.

The outstanding borrowings under the credit agreement bear interest at a rate elected by the Partnership that is equal to an alternative base rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.5% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable margin. The applicable margin ranges from ~~0.5%~~1.0% to ~~1.50%~~2.00% in the case of the alternative base rate and from ~~1.50%~~2.00% to ~~2.50%~~3.00% in the case of LIBOR, in each case depending on the amount of the loan outstanding in relation to the borrowing base. The Partnership is obligated to pay a quarterly commitment fee ranging from 0.375% to 0.500% per year on the unused portion of the borrowing base, which fee is also dependent on the amount of the loan outstanding in relation to the borrowing base. Loan principal may be optionally repaid from time to time without premium or penalty (other than customary LIBOR breakage), and is required to be repaid (a) to the extent that the loan amount exceeds the borrowing base, whether due to a borrowing base redetermination or otherwise (in some cases subject to a cure period) and (b) at the maturity date of July 8, 2019. The loan is secured by substantially all of the assets of the Partnership and its subsidiaries.

The credit agreement contains various affirmative, negative and financial maintenance covenants. These covenants, among other things, limit additional indebtedness, purchases of margin stock, additional liens, sales of assets, mergers and consolidations, dividends and distributions, transactions with affiliates and entering into certain swap agreements and require the maintenance of the financial ratios described below.



Financial Covenant		Required Ratio
Ratio of total debt to EBITDAX		Not greater than 4.0 to 1.0
Ratio of current assets to liabilities, as defined in the credit agreement		Not less than 1.0 to 1.0

The covenant prohibiting additional indebtedness allows for the issuance of unsecured debt of up to $250.0 million in the form of senior unsecured notes and, in connection with any such issuance, the reduction of the borrowing base by 25% of the stated principal amount of each such issuance. A borrowing base reduction in connection with such issuance may require a portion of the outstanding principal of the loan to be repaid.

The lenders may accelerate all of the indebtedness under the Partnership’s credit agreement upon the occurrence and during the continuance of any event of default. The Partnership’s credit agreement contains customary events of default, including non-payment, breach of covenants, materially incorrect representations, cross-default, bankruptcy and change of control. There are no cure periods for events of default due to non-payment of principal and breaches of negative and financial covenants, but non-payment of interest and breaches of certain affirmative covenants are subject to customary cure periods.

Partnership Equity Offering

In January 2017, the Partnership completed an underwritten public offering of 9,775,000 common units, which included 1,275,000 common units issued pursuant to an option to purchase additional common units granted to the underwriters. The Partnership received net proceeds from this offering of approximately $147.6 million, after deducting underwriting discounts and commissions and estimated offering expenses, of which Partnership used $120.5 million to repay the outstanding borrowings under its revolving credit agreement and intends to use the remaining net proceeds for general partnership purposes, which may include additional acquisitions.

Earnings Per Share

The Company’s basic earnings per share amounts have been computed based on the weighted-average number of shares of common stock outstanding for the period. Diluted earnings per share include the effect of potentially dilutive shares outstanding for the period. Additionally, for the diluted earnings per share computation, the per share earnings of the Partnership are included in the consolidated earnings per share computation based on the consolidated group’s holdings of the subsidiary.

A reconciliation of the components of basic and diluted earnings per common share is presented in the table below:

Performance Based Restricted Stock Units

To provide long-term incentives for the executive officers to deliver competitive returns to the Company’s stockholders, the Company has granted performance-based restricted stock units to eligible employees. The ultimate number of shares awarded from these conditional restricted stock units is based upon measurement of total stockholder return of the Company’s common stock (“TSR”) as compared to a designated peer group during a two-year or three-year performance period.

In February ~~2016,~~2017, eligible employees received performance restricted stock unit awards totaling ~~174,325~~37,440 units from which a minimum of 0% and a maximum of 200% units could be awarded. The awards have a performance period of January 1, ~~2016~~2017 to December 31, ~~2017~~2018 and cliff vest at December 31, ~~2017.~~2018. Eligible employees received additional performance restricted stock unit awards totaling ~~87,163~~74,880 units from which a minimum of 0% and a maximum of 200% units could be awarded. The awards have a performance period of January 1, ~~2016~~2017 to December 31, ~~2018~~2019 and cliff vest at December 31, ~~2018.~~

Phantom Units

Under the Viper LTIP, the Board of Directors of the General Partner is authorized to issue phantom units to eligible employees. The Partnership estimates the fair value of phantom units as the closing price of the Partnership’s common units on the grant date of the award, which is expensed over the applicable vesting period. Upon vesting the phantom units entitle the recipient one common unit of the Partnership for each phantom unit.

Midland Corporate Lease

Effective May 15, 2011, the Company occupied corporate office space in Midland, Texas under a lease with an initial five-year term, which was extended for an additional ten-years in November 2014. The office space is owned by Fasken, which is controlled by an affiliate of Wexford.

The Company paid rent of $0.3 million for the three months ended March 31, 2016.

Field Office Lease

The Company leased field office space in Midland, Texas from an unrelated third party commencing on March 1, 2011. On March 1, 2014, the building was purchased by WT Commercial Portfolio, LLC, which is controlled by an affiliate of Wexford. The term of the lease expires on February 28, 2018. During the third quarter of 2014, the Company entered into a sublease with Bison, in which Bison leased the field office space on the same terms as the Company’s lease for the remainder of the lease term. The Company paid rent of less than $0.1 million during the three months ended March 31, 2016. The Company received payments of less than $0.1 million from Bison in respect of this sublease during the three months ended March 31, 2016.

The Partnership - Lease Bonus

During the three months ended March 31, 2017, the Company paid the Partnership $1,500 in lease bonus payments to extend the term of one lease, reflecting an average bonus of $400 per acre. During the three months ended March 31, 2016, the Company paid the Partnership $0.1 million in lease bonus payments ~~under one lease~~ to extend the term of ~~the~~one lease, reflecting an average bonus of $2,500 per acre.

~~11.~~12. INCOME TAXES

The ~~Company incurred a~~Company’s effective income tax ~~net operating loss ("NOL")~~rates were 1.4% and 0.0% for the three months ended March 31, 2017 and 2016, respectively. Total income tax expense for the three months ended March 31, 2017 differed from amounts computed by applying the United States federal statutory tax rate to pre-tax income primarily due ~~principally~~ to current and deferred state income taxes and the change in valuation allowance that offsets the Company’s federal net deferred tax asset position. The Company incurs state income tax obligations in Texas, the primary state in which it operates, pursuant

to the ~~ability to expense certain intangible drilling and development costs under current regulations. There is no tax refund available to~~Texas margin tax. Any positive net taxable income generated by the Company ~~nor is there any current~~for federal income tax ~~payable. In light of~~purposes for the ~~impairment of oil and gas properties, management~~three months ended March 31, 2017 is expected to be offset by federal net operating loss (“NOL”) carryforwards, for which a full valuation allowance has ~~recorded a $10.1~~been provided. During the three months ended March 31, 2017, the Company reduced its valuation allowance against its federal NOL by $27.4 million, ~~valuation against the Company's federal NOLs,~~ bringing the total valuation allowance to ~~$71.2~~$87.0 million. The valuation allowance reduces the Company’s deferred assets to a zero value, as management does not believe that it is more-likely-than-not that this portion of the Company's NOLs are realizable. Management believes that the balance of the Company's NOLs are realizable only to the extent of future taxable income primarily related to the excess of book carrying value of properties over their respective tax bases. No other sources of future taxable income are considered in this judgment.

~~12.~~13. DERIVATIVES

All derivative financial instruments are recorded at fair value. The Company has not designated its derivative instruments as hedges for accounting purposes and, as a result, marks its derivative instruments to fair value and recognizes the cash and non-cash changes in fair value in the combined consolidated statements of operations under the caption “Gain (loss) on derivative instruments, net.”

The Company has used fixed price swap contracts, fixed price basis swap contracts and costless collars with corresponding put and call options to reduce price volatility associated with certain of its oil and natural gas sales. With respect to the Company’s fixed price swap contracts and fixed price basis swap contracts, the counterparty is required to make a payment to the Company if the settlement price for any settlement period is less than the swap or basis price, and the Company is required to make a payment to the counterparty if the settlement price for any settlement period is greater than the swap or basis price. The Company has fixed price basis swaps for the spread between the WTI Midland price and the WTI Cushing price. Under the Company’s costless collar contracts, the counterparty is required to make a payment to the Company if the settlement price for any settlement period is less than the put option price, and the Company is required to make a payment to the counterparty if the settlement price for any settlement period is greater than the call option price. If the settlement price is between the put and the call price, there is no payment required. The Company’s derivative contracts are based upon reported settlement prices on commodity exchanges, with crude oil derivative settlements based on New York Mercantile Exchange West Texas Intermediate pricing and with natural gas derivative settlements based on the New York Mercantile Exchange Henry Hub pricing.

By using derivative instruments to hedge exposure to changes in commodity prices, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk. The Company’s counterparties are participants in the secured second amended and restated credit agreement, which is secured by substantially all of the assets of the guarantor subsidiaries; therefore, the Company is not required to post any collateral. The Company does not require collateral from its counterparties. The Company has entered into derivative instruments only with counterparties that are also lenders in our credit facility and have been deemed an acceptable credit risk.

As of March 31, 2017, the Company had the following outstanding derivative contracts. When aggregating multiple contracts, the weighted average contract price is disclosed.



	2017				2018
	Volume (Bbls/MMBtu)	Fixed Price Swap (per Bbl/MMBtu)			Volume (Bbls/MMBtu)	Fixed Price Swap (per Bbl/MMBtu)

Balance sheet offsetting of derivative assets and liabilities

The fair value of swaps is generally determined using established index prices and other sources which are based upon, among other things, futures prices and time to maturity. These fair values are recorded by netting asset and liability positions that are with the same counterparty and are subject to contractual terms which provide for net settlement.

The following tables present the gross amounts of recognized derivative assets and liabilities, the amounts offset under master netting arrangements with counterparties and the resulting net amounts presented in the Company’s consolidated balance sheets as of March 31, ~~2016~~2017 and December 31, ~~2015.~~2016.

14. FAIR VALUE MEASUREMENTS

Fair value is defined as 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. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

~~Diamondback Energy, Inc. and Subsidiaries~~

~~Notes to Consolidated Financial Statements-(Continued)~~

~~(Unaudited)~~

The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. The Company’s assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. The Company uses appropriate valuation techniques based on available inputs to measure the fair values of its assets and liabilities.

Level 1 - Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date.

Level 2 - Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date.

Level 3 - Unobservable inputs that are not corroborated by market data and may be used with internally developed methodologies that result in management’s best estimate of fair value.

Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Certain assets and liabilities are reported at fair value on a recurring basis, including the Company’s derivative instruments. The fair values of the Company’s fixed price ~~crude oil~~ swaps, fixed price basis swaps and costless collars are measured internally using established commodity futures price strips for the underlying commodity provided by a reputable third party, the contracted notional volumes, and time to maturity. These valuations are Level 2 inputs.

The following table provides fair value measurement information for financial assets and liabilities measured at fair value on a recurring basis as of March 31, ~~2016~~2017 and December 31, ~~2015.~~2016.

~~14.~~15. COMMITMENTS AND CONTINGENCIES

The Company could be subject to various possible loss contingencies which arise primarily from interpretation of federal and state laws and regulations affecting the natural gas and crude oil industry. Such contingencies include differing interpretations as to the prices at which natural gas and crude oil sales may be made, the prices at which royalty owners may be paid for production from their leases, environmental issues and other matters. Management believes it has complied with the various laws and regulations, administrative rulings and interpretations.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our unaudited consolidated financial statements and notes thereto presented in this report as well as our audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, ~~2015.~~2016. The following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs, and expected performance. Actual results and the timing of events may differ materially from those contained in these forward-looking statements due to a number of factors. See “Part II. Item 1A. Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

Overview

We are an independent oil and natural gas company focused on the acquisition, development, exploration and exploitation of unconventional, onshore oil and natural gas reserves in the Permian Basin in West Texas. Our activities are primarily directed at the ~~Clearfork,~~horizontal development of the Wolfcamp and Spraberry formations in the Midland Basin and the Wolfcamp ~~Cline, Strawn~~ and ~~Atoka~~Bone Spring formations ~~which we refer to as~~in the ~~Wolfberry play.~~Delaware Basin. We intend to ~~grow~~continue to develop our reserves and increase production through development drilling and exploitation and exploration activities on our multi-year inventory of identified potential drilling locations and through acquisitions that meet our strategic and financial objectives, targeting oil-weighted reserves. Substantially all of our revenues are generated through the sale of oil, natural gas liquids and natural gas production. ~~Our~~

The following table sets forth our production ~~was approximately 76% oil, 13% natural gas liquids and 11% natural gas~~data for the ~~three months ended March 31, 2016, and was approximately 77% oil, 13% natural gas liquids and 10% natural gas for the three months ended March 31, 2015.~~ periods indicated:



	Three Months Ended March 31,
	2017		2016
Oil (Bbls)	75	%	76	%
Natural gas (Mcf)	11	%	11	%
Natural gas liquids (Bbls)	14	%	13	%
	100	%	100	%

On March 31, ~~2016,~~2017, our net acreage position in the Permian Basin was approximately ~~85,816~~191,727 net acres.

The challenging commodity price environment that we experienced in ~~2015~~2016 has continued in 2017. Commodity prices improved during the first quarter of ~~2016, with the posted price of WTI dropping to as low as $26.68 in January 2016. Commodity prices improved at the end of the first quarter 2016,~~2017, but continue to be volatile. We believe we remain well-positioned in this environment. During ~~2015,~~2016, we again demonstrated our operational focus on achieving best-in-class execution, low-cost operations and a conservative balance sheet as we continued to reduce drilling days, well costs and operating expenses while maintaining what we believe to be a peer leading leverage ratio. We ~~intend to continue~~have continued our operational focus in ~~2016, emphasizing financial discipline over growth.~~2017 and have further decreased drilling times, well costs and operating expenses. Our leading-edge Midland Basin costs to drill, complete and equip wells are currently below $6.0 million for a 10,000 foot lateral well and below $5.0 million for a 7,500 foot lateral well. We have successfully drilled three 13,000 foot lateral wells in Midland County to date.During the first quarter of 2017, we drilled one well in Ward County and one well in Reeves County. We also drilled a three-well pad (7,500 foot lateral each) in Howard County. With recent improvement in oil prices, we have retained our third horizontal rig and added a second dedicated completion crew to decrease our backlog of drilled but uncompleted wells. We will continue monitoring the ongoing commodity price environment and expect to retain the financial flexibility to adjust our drilling and completion plans in response to market conditions. We are prepared to add a fourth horizontal rig early in the third quarter of 2016 in the event oil prices continue to strengthen and we are prepared to remain at three horizontal drilling rigs or decelerate our drilling program if commodity prices deteriorate.

~~2016 Highlights~~

~~Common stock transactions~~

In January 2016, we completed an underwritten public offering of 4,600,000 shares of common stock, which included 600,000 shares of common stock issued pursuant to an option to purchase additional shares granted to the underwriter. The stock was sold to the underwriter at $55.33 per share and we received proceeds of approximately $254.5 million from the sale of these shares of common stock, net of offering expenses and underwriting discounts and commissions.

~~Operational Update~~

During the three months ended March 31, 2016, we drilled 16 gross (13 net) horizontal wells and one gross (one net) vertical well and participated in the drilling of two gross (one net) non-operated wells in the Permian Basin. We completed a total ofcurrently operating eight horizontal wells, which included our initial five wells in Glasscock County. A three well pad targeting the Lower Spraberry, Wolfcamp A and Wolfcamp B horizons came on line in January 2016. The combined 30-day initial production rate for the three laterals was 3,644 BOE/d (75% oil) from an average lateral length of 7,396 feet. A second two well pad targeting the Wolfcamp A and Wolfcamp B horizons was brought on line in February 2016. The combined 30-day initial production rate for the two laterals was 2,312 BOE/d (84% oil) from an average lateral length of 7,465 feet. We have drilled another two-well pad in Glasscock County that is waiting on completion.

In Howard County we have two three-well pads waiting on completion. Both pads target the Lower Spraberry, Wolfcamp A and Wolfcamp B intervals. We intend to begin completing the first pad in May 2016 and the second pad in June 2016.

~~We entered 2016 drilling with three horizontal~~ rigs and were prepared to release one of the rigs in early February. However, with recent improvement in oil prices, we have retained our third horizontal rig and are prepared to add a fourth horizontal rig early in the third quarter of 2016 in the event oil prices continue to strengthen.three completion crews. We will continue monitoring commodity prices and overall market conditions and can adjust our rig cadence up or down ~~accordingly.~~in response to changes in commodity prices and overall market conditions. We will continue to evaluate adding additional rigs throughout the year if commodity prices strengthen.

2017 Highlights

Our Recent Acquisition

On February 28, 2017, we completed our acquisition of oil and natural gas properties, midstream assets and other related assets in the Delaware Basin for an aggregate purchase price consisting of $1.74 billion in cash and 7.69 million shares of our common stock, of which approximately 1.15 million shares were placed in an indemnity escrow. This transaction includes the acquisition of (i) approximately 100,306 gross (80,339 net) acres primarily in Pecos and Reeves counties for approximately $2.5 billion and (ii) midstream assets for approximately $47.6 million. We used the

net proceeds from the December 2016 equity offering, net proceeds from the December 2016 debt offering, cash on hand and other financing sources to fund the cash portion of the purchase price for this acquisition.

Viper Equity Offering

In January 2017, Viper completed an underwritten public offering of 9,775,000 common units, which included 1,275,000 common units issued pursuant to an option to purchase additional common units granted to the underwriters. Viper received net proceeds from this offering of approximately $147.6 million, after deducting underwriting discounts and commissions and estimated offering expenses, of which Viper used $120.5 million to repay the outstanding borrowings under its revolving credit agreement and intends to use the remaining net proceeds for general partnership purposes, which may include additional acquisitions.

Operational Update

During the first quarter of ~~2016,~~2017, we ~~slowed our~~drilled 28 gross (23 net) horizontal wells, two gross (two net) of which were in the Delaware Basin. We turned 26 gross (20 net) wells into production, of which two gross (two net) were wells in the Delaware Basin that were drilled by the prior operator. We also participated in the drilling of six gross (one net) wells and in the completion ~~schedule in response to lower commodity prices. However, we have recently contracted a second completion crew to begin to reduce our inventory~~ of ~~drilled but uncompleted~~eight gross (one net) non-operated wells.

~~During~~We are currently operating eight rigs and intend to operate between six and ten drilling rigs in 2017 across our asset base in the Midland and Delaware Basins. We plan to operate four to six of these rigs in the Midland Basin targeting horizontal development of the Wolfcamp and Spraberry formations, while the remainder of the rigs are expected to operate in the Delaware Basin targeting the Wolfcamp and Bone Spring formations.

In the Midland Basin, we continue to see positive well results from our core development areas in Midland, Glasscock, Howard, Andrews and Martin Counties. Assuming commodity prices at current levels, we anticipate operating one rig in Glasscock County, one rig in Howard County and three or more rigs in Midland, Martin and Andrews Counties through the remainder of 2017.

In the Delaware Basin, we are currently operating two drilling rigs and plan to operate three rigs on this acreage through 2017 targeting the Wolfcamp and Bone Spring formations. Our first operated well results in the Delaware Basin confirm the productivity of the asset base, and we are focused on transferring our best practices on cost control from the Midland Basin to the Delaware Basin.

We continue to focus on low cost operations and best in class execution. In doing so, we are focused on controlling oilfield service costs as our service providers seek to increase pricing after two years of declining service costs during the downturn in the oil market. To combat rising service costs, we have looked to lock in pricing for dedicated activity levels and will continue to seek opportunities to control additional well cost where possible, including de-bundling of completion costs. We believe that our 2017 drilling and completion budget will cover potential increases in our service costs during the year.

The following table summarizes our average daily production for the periods presented:



	Three Months Ended March 31,
	2017	2016
Oil (Bbls)/d	46,201	28,951
Natural Gas (Mcf)/d	40,923	25,458
Natural Gas Liquids (Bbls)/d	8,589	5,114
Total average production per day	61,610	38,308

Our average daily production for the three months ended March 31, 2017 as compared to the three months ended March 31, 2016 ~~our average daily production was approximately 38,308 BOE/d, consisting of 28,951 Bbls/d of oil, 25,458 Mcf/d of natural gas and 5,114 Bbls/d of natural gas liquids, an increase of 7,672~~increased 23,302 BOE/d, or ~~25.0%, from average daily production of 30,636 BOE/d for the three months ended March 31, 2015, consisting of 23,687 Bbls/d of oil, 17,765 Mcf/d of natural gas and 3,988 Bbls/d of natural gas liquids.~~60.8%.

Sources of Our Revenue

Our main source of revenues are derived from the sale of oil and natural gas production, as well as the sale of natural gas liquids that are extracted from our natural gas during processing. Our oil and natural gas revenues do not include the effects of derivatives. For the three months ended March 31, 2016, our revenues were derived 90% from oil sales, 5% from natural gas liquids sales and 5% from natural gas sales and for the three months ended March 31, 2015, our revenues were derived 92% from oil sales, 4% from natural gas liquids sales and 4% from natural gas sales. Our revenues may vary significantly from period to period as a result of changes in volumes of production sold, production mix or commodity prices.

The following table presents the breakdown of our revenues for the following periods:



	Three Months Ended March 31,
	2017		2016

Oil sales	89	%	90	%
Natural gas sales	4	%	5	%
Natural gas liquid sales	7	%	5	%
	100	%	100	%

Since our production consists primarily of oil, our revenues are more sensitive to fluctuations in oil prices than they are to fluctuations in natural gas liquids or natural gas prices. Oil, natural gas liquids and natural gas prices have historically been volatile. During ~~2015,~~2016, West Texas Intermediate posted prices ranged from ~~$34.55~~$26.19 to ~~$61.36~~$54.01 per Bbl and the Henry Hub spot market price of natural gas ranged from ~~$1.63~~$1.49 to ~~$3.32~~$3.80 per MMBtu. On March 31, ~~2016,~~2017, the West Texas Intermediate posted price for crude oil was ~~$36.94~~$50.54 per Bbl and the Henry Hub spot market price of natural gas was ~~$1.98~~$3.13 per MMBtu. Lower commodity prices may not only decrease our revenues, but also potentially the amount of oil and natural gas that we can produce economically. Lower oil and natural gas prices may also result in a reduction in the borrowing base under our credit agreement, which may be redetermined at the discretion of our lenders.

~~As a result of the decline in prices during the three months ended March 31, 2016, the Company recorded non-cash ceiling test impairment for the three months ended March 31, 2016 of $30.8 million.~~

Although commodity prices improved at the end of the first quarter 2016, they remain volatile. If prices remain at or below the current low levels, subject to numerous factors and inherent limitations, we will incur an additional non-cash full cost impairment in the second quarter of 2016, which will have an adverse effect on our results of operations.

Comparison of the Three Months Ended March 31, ~~2016~~2017 and ~~2015~~2016

Oil, Natural Gas Liquids and Natural Gas Revenues. Our oil, natural gas liquids and natural gas revenues ~~decreased~~increased by approximately ~~$13.9~~$145.0 million, or ~~14%~~166%, to $232.5 million for the three months ended March 31, 2017 from $87.5 million for the three months ended March 31, ~~2016 from $101.4 million for the three months ended March 31, 2015.~~2016. Our revenues are a function of oil, natural gas liquids and natural gas production volumes sold and average sales prices received for those volumes. Average daily production sold increased by ~~7,672~~23,302 BOE/d to 61,610 BOE/d during the three months ended March 31, 2017 from 38,308 BOE/d during the three months ended March 31, ~~2016 from 30,636 BOE/d during the three months ended March 31, 2015.~~2016. The total ~~decrease~~increase in revenue of approximately ~~$13.9~~$145.0 million is largely attributable to ~~lower average sales prices partially offset by~~ higher oil, natural gas liquids and natural gas production volumes and higher average sales prices for the three months ended March 31, ~~2016~~2017 as compared to the three months ended March 31, ~~2015.~~2016. The increases in production volumes were due to a combination of increased drilling activity and growth through acquisitions. Our production increased by ~~502,682~~1,523,572 Bbls of oil, ~~106,467~~307,604 Bbls of natural gas liquids and ~~717,839~~1,366,423 Mcf of natural gas for the three months ended March 31, ~~2016~~2017 as compared to the three months ended March 31, ~~2015.~~2016.

The net dollar effect of the ~~decreases~~increases in prices of approximately ~~$39.0~~$94.0 million (calculated as the change in period-to-period average prices multiplied by current period production volumes of oil, natural gas liquids and natural gas) and the net dollar effect of the increase in production of approximately ~~$25.1~~$51.0 million (calculated as the increase in period-to-period volumes for oil, natural gas liquids and natural gas multiplied by the period average prices) are shown below.

(1)	Production volumes are presented in Bbls for oil and natural gas liquids and Mcf for natural gas.

Lease Bonus Revenue. Lease bonus revenue was $1.6 million for the three months ended March 31, 2017 attributable to lease bonus payments to extend the term of one lease, reflecting an average bonus of $2,500 per acre. We had no lease bonus revenue for the three months ended March 31, 2016.

Midstream Services Revenue. Midstream services revenue was $1.1 million for the three months ended March 31, 2017. We had no midstream services revenue for the three months ended March 31, 2016. Our midstream services revenue represents fees charged to our joint interest owners and third parties for the transportation of oil and natural gas along with water gathering and related disposal facilities. These assets complement our operations in areas where we have significant production.

Lease Operating Expense. Lease operating expense was $26.6 million ($4.80 per BOE) for the three months ended March 31, 2017 as compared to $18.2 million ($5.23 per BOE) for the three months ended March 31, ~~2016, a decrease of $4.2 million, or 19%, from $22.5 million ($8.14 per BOE) for the three months ended March 31, 2015.~~2016. The decrease ~~is due to~~in lease operating expense per BOE was a ~~reduction in service costs resulting from decreased commodity prices.~~result of steady lease operating expenses offset by higher production volumes.

Production and Ad Valorem Tax Expense. Production and ad valorem taxes were $15.7 million for the three months ended March 31, 2017, an increase of $7.8 million, or 98%, from $8.0 million for the three months ended March 31, ~~2016, a decrease of $0.4 million, or 5%, from $8.4 million for the three months ended March 31, 2015.~~2016. In general, production taxes and ad valorem taxes are directly related to commodity price changes; however, Texas ad valorem taxes are based upon prior year commodity prices, among other factors, whereas production taxes are based upon current year commodity prices. During the three months ended March 31, ~~2016,~~2017, our production and ad valorem taxes per BOE ~~decreased~~increased by ~~$0.76~~$0.56 as compared to the three months ended March 31, ~~2015,~~2016, primarily ~~reflecting~~due to increased commodity prices and production volumes.

Midstream Services Expense. Midstream services expense was $0.9 million for the ~~impact of lower~~three months ended March 31, 2017. We had no midstream services expense for the three months ended March 31, 2016. Midstream services represent costs incurred to operate and maintain our oil and natural gas ~~prices on production taxes in 2016, offset by an increase in ad valorem taxes primarily as a result of increased production.~~gathering and transportation systems, natural gas lift, compression infrastructure and water transportation facilities.

Depreciation, Depletion and Amortization. Depreciation, depletion and amortization expense ~~decreased $17.6~~increased $16.9 million, or ~~30%~~40%, to $58.9 million for the three months ended March 31, 2017 from $42.1 million for the three months ended March 31, ~~2016 from $59.7 million for the three months ended March 31, 2015.~~2016.

The ~~decreases~~increase in depletion of proved oil and natural gas properties of ~~$17.6~~$16.5 million for the three months ended March 31, ~~2016~~2017 as compared to the three months ended March 31, ~~2015~~2016 resulted primarily from ~~the impairment of oil~~higher production levels and ~~gas properties recorded~~an increase in ~~the first quarter of 2016.~~net book value on new reserves added.

Impairment of Oil and Gas Properties. During the three months ended March 31, 2016, we recorded an impairment of oil and gas properties of $30.8 million as a result of the significant decline in commodity prices, which resulted in a reduction of the discounted present value of our proved oil and natural gas reserves. We did not record an impairment of oil and gas properties during the three months ended March 31, 2017.

General and Administrative Expense. General and administrative expense increased ~~$4.8~~$0.8 million from ~~$8.2 million for the three months ended March 31, 2015 to~~ $13.0 million for the three months ended March 31, ~~2016.~~2016 to $13.7 million for the three months ended March 31, 2017. The increase was primarily due to an increase in salaries and benefits of $2.4 million partially offset by a decrease in non-cash equity compensation of ~~$ 4.0 million and an increase in salaries and benefits of $0.8~~$1.6 million.

Net Interest Expense. Net interest expense for the three months ended March 31, ~~2016~~2017 was ~~$10.0~~$12.2 million as compared to ~~$10.5~~$10.0 million for the three months ended March 31, ~~2015, a decrease~~2016, an increase of ~~$0.5~~$2.2 million. This ~~decrease~~increase was due primarily to ~~the lower average level of outstanding borrowings under~~interest on our ~~credit facility during the three months ended March 31, 2016 as compared to the three months ended March 31, 2015.~~senior notes.

Derivatives. We are required to recognize all derivative instruments on the balance sheet as either assets or liabilities measured at fair value. We have not designated our derivative instruments as hedges for accounting purposes. As a result, we mark our derivative instruments to fair value and recognize the cash and non-cash changes in fair value on derivative instruments in our consolidated statements of operations under the line item captioned “Gain (loss) on derivative instruments, net.” For the three months ended March 31, ~~2016 and 2015,~~2017, we had a cash loss on settlement of derivative instruments of $1.7 million as compared to a cash gain on settlement of derivative instruments of $5.1 million ~~and $43.6 million, respectively.~~for the three months ended March 31, 2016. For the three months ended March 31, ~~2016 and 2015,~~2017, we had a ~~negative~~positive change in the fair value of open derivative instruments of $39.4 million as compared to a negative change of $3.7 million ~~and $25.2 million, respectively.~~during the three months ended March 31, 2016.

Provision for Income ~~Tax Expense (Benefit).~~Taxes. We ~~had no~~recorded an income tax ~~benefit~~provision for $2.0 million the three months ended March 31, 2017. We did not record an income tax provision or ~~expense~~benefit for the three months ended March 31, 2016 as compared to income tax expense of $3.4 million for the three months ended March 31, 2015. Our effective tax rate was 34.4% for the three months ended March 31, 2015. During the three months ended March 31, 2016, we recorded a valuation allowance as management does not believe that it is more-likely-than-not that its net operating losses are realizable.2016.

Liquidity and Capital Resources

Our primary sources of liquidity have been proceeds from our public equity offerings, borrowings under our revolving credit facility, proceeds from the issuance of the senior notes and cash flows from operations. Our primary use of capital has been for the acquisition, development and exploration of oil and natural gas properties. As we pursue reserves and production growth, we regularly consider which capital resources, including equity and debt financings, are available to meet our future financial obligations, planned capital expenditure activities and liquidity requirements. Our future ability to grow proved reserves and production will be highly dependent on the capital resources available to us.

Liquidity and Cash Flow

Our cash flows for the three months ended March 31, ~~2016~~2017 and ~~2015~~2016 are presented below:

Operating Activities

Net cash provided by operating activities was $175.9 million for the three months ended March 31, 2017 as compared to $72.8 million for the three months ended March 31, ~~2016 as compared to $99.1 million for the three months ended March 31, 2015.~~2016. The ~~decrease~~increase in operating cash flows is primarily ~~the~~due to a result of ~~the decrease~~increases in our oil and natural gas revenues due to ~~a 32% decrease~~an increase in ~~our net realized sales prices.~~average prices and production growth during the three months ended March 31, 2017.

Our operating cash flow is sensitive to many variables, the most significant of which is the volatility of prices for the oil and natural gas we produce. Prices for these commodities are determined primarily by prevailing market conditions. Regional and worldwide economic activity, weather and other substantially variable factors influence market conditions for these products. These factors are beyond our control and are difficult to predict. See “—Sources of our revenue” above.

Investing Activities

The purchase and development of oil and natural gas properties accounted for the majority of our cash outlays for investing activities. Net cash used in investing activities was ~~$107.2~~$1,825.5 million and ~~$153.6~~$107.2 million during the three months ended March 31, 2017 and 2016, respectively.

During the three months ended March 31, 2017, we spent (a) $116.2 million on capital expenditures in conjunction with our development program, in which we drilled 28 gross (23 net) horizontal wells, completed 26 gross (20 net) horizontal wells and ~~2015, respectively.~~participated in the drilling of six gross (one net) non-operated wells in the Permian Basin, (b) $1,760.8 million on leasehold acquisitions, (c) $48.3 million for midstream assets and (d) $11.9 million for the purchase of other property and equipment.

During the three months ended March 31, 2016, we spent $86.3 million on capital expenditures in conjunction with our drilling program and related infrastructure projects, in which we drilled 16 gross (13 net) horizontal wells and one gross (one net) vertical ~~well~~wells and participated in the drilling of two gross (one net) non-operated wells in the Permian Basin. We spent an additional $16.9 million on leasehold acquisitions, $2.1 million on royalty interest acquisitions and $1.1 million for the purchase of other property and equipment.

During the three months ended March 31, 2015, we spent $151.4 million on capital expenditures in conjunction with our drilling program and related infrastructure projects, in which we drilled 15 gross (13 net) horizontal wells and two gross (one net) vertical wells. We spent an additional $2.0 million on leasehold costs and $0.2 million for the purchase of other property and equipment.

Our investing activities for the three months ended March 31, ~~2016~~2017 and ~~2015~~2016 are summarized in the following table:

2024 Senior Notes

On October 28, 2016, we issued $500.0 million in aggregate principal amount of 4.750% senior notes due 2024, which we refer to as the 2024 senior notes. The 2024 senior notes bear interest at a rate of 4.750% per annum, payable semi-annually, in arrears on May 1 and November 1 of each year, commencing on May 1, 2017 and will mature on November 1, 2024. All of our existing and future restricted subsidiaries that guarantee our revolving credit facility or certain other debt guarantee the 2024 senior notes; provided, however, that the 2024 senior notes are not guaranteed by Viper, Viper Energy Partners GP LLC, Viper Energy Partners LLC or Rattler Midstream LLC, and will not be guaranteed by any of the our future unrestricted subsidiaries.

The 2024 senior notes were issued under, and are governed by, an indenture among us, the subsidiary guarantors party thereto and Wells Fargo, as the trustee, as supplemented. The 2024 indenture contains certain covenants that, subject to certain exceptions and qualifications, among other things, limit our ability and the ability of the restricted subsidiaries to incur or guarantee additional indebtedness, make certain investments, declare or pay dividends or make other distributions on capital stock, prepay subordinated indebtedness, sell assets including capital stock of restricted subsidiaries, agree to payment restrictions affecting our restricted subsidiaries, consolidate, merge, sell or otherwise dispose of all or substantially all of our assets, enter into transactions with affiliates, incur liens, engage in business other than the oil and gas business and designate certain of our subsidiaries as unrestricted subsidiaries.

We may on any one or more occasions redeem some or all of the 2024 senior notes at any time on or after November 1, 2019 at the redemption prices (expressed as percentages of principal amount) of 103.563% for the 12-month period beginning on November 1, 2019, 102.375% for the 12-month period beginning on November 1, 2020, 101.188% for the 12-month period beginning on November 1, 2021 and 100.000% beginning on November 1, 2022 and at any time thereafter with any accrued and unpaid interest to, but not including, the date of redemption. Prior to November 1, 2019, we may on any one or more occasions redeem all or a portion of the 2024 senior notes at a price equal to 100% of the principal amount of the 2024 senior notes plus a “make-whole” premium and accrued and unpaid interest to the redemption date. In addition, any time prior to November 1, 2019, we may on any one or more occasions redeem the 2024 senior notes in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the 2024 senior notes issued prior to such date at a redemption price of 104.750%, plus accrued and unpaid interest to the redemption date, with an amount equal to the net cash proceeds from certain equity offerings.

In connection with the issuance of the 2024 senior notes, we and the subsidiary guarantors entered into a registration rights agreement with the initial purchasers on October 28, 2016, pursuant to which we agreed to file a registration statement with respect to an offer to exchange the 2024 senior notes for a new issue of substantially identical debt securities registered under the Securities Act. Under the 2024 registration rights agreement, we also agreed to use its commercially reasonable efforts to have the registration statement declared effective by the SEC on or prior to the 360th day after the issue date of the 2024 senior notes and to keep the exchange offer open for not less than 30 days (or longer if required by applicable law). We may be required to file a shelf registration statement to cover resales of the 2024 senior notes under certain circumstances. If we fail to satisfy these obligations under the 2024 registration rights agreement, we agreed to pay additional interest to the holders of the 2024 senior notes as specified in the 2024 registration rights agreement.

2025 Senior Notes

On December 20, 2016, we issued $500.0 million in aggregate principal amount of 5.375% Senior Notes due 2025, which we refer to as the 2025 senior notes. The 2025 senior notes bear interest at a rate of 5.375% per annum, payable semi-annually, in arrears on May 31 and November 30 of each year, commencing on May 31, 2017 and will mature on May 31, 2025. All of our existing and future restricted subsidiaries that guarantee our revolving credit facility or certain other debt guarantee the 2025 senior notes, provided, however, that the 2025 senior notes are not guaranteed by Viper, Viper Energy Partners GP LLC, Viper Energy Partners LLC or Rattler Midstream LLC, and will not be guaranteed by any of our future unrestricted subsidiaries.

The 2025 senior notes were issued under an indenture, dated as of December 20, 2016, among us, the guarantors party thereto and Wells Fargo, as the trustee. The 2025 Indenture contains certain covenants that, subject to certain exceptions and qualifications, among other things, limit our ability and the ability of the restricted subsidiaries to incur or guarantee additional indebtedness, make certain investments, declare or pay dividends or make other distributions on capital stock, prepay subordinated indebtedness, sell assets including capital stock of restricted subsidiaries, agree to payment restrictions affecting our restricted subsidiaries, consolidate, merge, sell or otherwise dispose of all or substantially all of our assets, enter into transactions with affiliates, incur liens, engage in business other than the oil and gas business and designate certain of our subsidiaries as unrestricted subsidiaries.

We may on any one or more occasions redeem some or all of the 2025 senior notes at any time on or after May 31, 2020 at the redemption prices (expressed as percentages of principal amount) of 104.031% for the 12-month period beginning on May 31, 2020, 102.688% for the 12-month period beginning on May 31, 2021, 101.344% for the 12-month period beginning on May 31, 2022 and 100.000% beginning on May 31, 2023 and at any time thereafter with any accrued and unpaid interest to, but not including, the date of redemption. Prior to May 31, 2020, we may on any one or more occasions redeem all or a portion of the 2025 senior notes at a price equal to 100% of the principal amount of the 2025 senior notes plus a “make-whole” premium and accrued and unpaid interest to the redemption date. In addition, any time prior to May 31, 2020, we may on any one or more occasions redeem the 2025 senior notes in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the 2025 senior notes issued prior to such date at a redemption price of 105.375%, plus accrued and unpaid interest to the redemption date, with an amount equal to the net cash proceeds from certain equity offerings.

In connection with the issuance of the 2025 senior notes, we and the subsidiary guarantors entered into a registration rights agreement with the initial purchasers on December 20, 2016, pursuant to which we agreed to file a registration statement with respect to an offer to exchange the 2025 senior notes for a new issue of substantially identical debt securities registered under the Securities Act. Under the 2025 registration rights agreement, we also agreed to use its commercially reasonable efforts to have the registration statement declared effective by the SEC on or prior to the 360th day after the issue date of the 2025 senior notes and to keep the exchange offer open for not less than 30 days (or longer if required by applicable law). We may be required to file a shelf registration statement to cover resales of the 2025 senior notes under certain circumstances. If we fail to satisfy these obligations under the 2025 registration rights agreement, we agreed to pay additional interest to the holders of the 2025 senior notes as specified in the 2025 registration rights agreement.

On April 26, 2017, we filed with the SEC our Registration Statement on Form S-4 relating to the exchange offers of the 2024 senior notes and the 2025 senior notes for substantially identical debt securities registered under the Securities Act.

Second Amended and Restated Credit Facility

Our second amended and restated credit agreement, dated November 1, 2013, as amended, ~~on June 9, 2014 and November 13, 2014,~~ with a syndicate of banks, including Wells Fargo, as administrative agent, sole book runner and lead arranger, provides for a revolving credit facility in the maximum amount of $2.0 ~~billion, subject to scheduled semi-annual and other elective collateral borrowing base redeterminations based on our oil and natural gas reserves~~

and other factors. The borrowing base is scheduled to be re-determined semi-annually with effective dates of May 1st and November 1st. In addition, we may request up to three additional redeterminations of the borrowing base during any 12-month period.billion. As of March 31, ~~2016,~~2017, the borrowing base was ~~$750.0 million,~~set at $1.0 billion, although we had elected a commitment amount of $500.0 million. As of March 31, ~~2016,~~2017, we had no outstanding borrowings and $500.0 million available for future borrowings under this facility. As of March 31, 2016, the loan was guaranteed by us, Diamondback E&P LLC and White Fang Energy LLC and will also be guaranteed by any of our future restricted subsidiaries. The credit agreement is also secured by substantially all of our assets and the assets of Diamondback O&G LLC and the guarantors. In connection with our spring ~~2016~~2017 redetermination, the agent lender under ~~our~~the credit agreement has recommended that our borrowing base be ~~reduced~~increased to ~~$700.0 million due to a decline in pricing.~~$1.5 billion. This ~~reduction~~increase is subject to the approval of the required other lenders. Regardless of such adjustment, we have elected to ~~continue to limit~~increase the lenders’ aggregate commitment to ~~$500.0~~$750.0 million.

The outstanding borrowings under the credit agreement bear interest at a rate elected by us that is equal to an alternative base rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.50% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable margin. The applicable margin ranges from 0.50% to 1.50% in the case of the alternative base rate and from 1.50% to 2.50% in the case of LIBOR, in each case depending on the amount of the loan outstanding in relation to the borrowing base. We are obligated to pay a quarterly commitment fee ranging from 0.375% to 0.500% per year on the unused portion of the borrowing base, which fee is also dependent on the amount of the loan outstanding in relation to the borrowing base. Loan principal may be optionally repaid from time to time without premium or penalty (other than customary LIBOR breakage), and is required to be repaid (a) to the extent that the loan amount exceeds the borrowing base, whether due to a borrowing base redetermination or otherwise (in some cases subject to a cure period), (b) in an amount equal to the net cash proceeds from the sale of property when a borrowing base deficiency or event of default exists under the credit agreement and (c) at the maturity date of November 1, 2018.



Financial Covenant	Required Ratio
Ratio of total debt to EBITDAX	Not greater than 4.0 to 1.0
Ratio of current assets to liabilities, as defined in the credit agreement	Not less than 1.0 to 1.0

The covenant prohibiting additional indebtedness, as amended in December 2016, allows for the issuance of unsecured debt of up to ~~$750.0 million~~$1.0 billion in the form of senior or senior subordinated notes and, in connection with any such issuance, the reduction of the borrowing base by 25% of the stated principal amount of each such issuance. A borrowing base reduction in connection with such issuance may require a portion of the outstanding principal of the loan to be repaid. As of March 31, ~~2016,~~2017, we had ~~$450.0 million~~$1.0 billion in aggregate principal amount of senior notes outstanding.

As of March 31, ~~2016,~~2017, we were in compliance with all financial covenants under our revolving credit facility. The lenders may accelerate all of the indebtedness under our revolving credit facility upon the occurrence and during the continuance of any event of default. The credit agreement contains customary events of default, including non-payment, breach of covenants, materially incorrect representations, cross-default, bankruptcy and change of control. With certain specified exceptions, the terms and provisions of our revolving credit facility generally may be amended with the consent of the lenders holding a majority of the outstanding loans or commitments to lend.

Viper’s Facility-Wells Fargo Bank

~~On July 8, 2014,~~ Viper ~~entered into~~is a party to a $500.0 million, secured revolving credit agreement, dated as of July 8, 2014, as amended, with Wells Fargo ~~Bank,~~ as the administrative agent, sole book runner and lead ~~arranger.~~arranger, and certain other lenders party thereto. The credit agreement which was amended August 15, 2014 to add additional lenders to the lending group, provides for a revolving credit facility in the maximum amount of $500.0 million, subject to scheduled semi-annual and other elective collateral borrowing base redeterminations basedmatures on ~~Viper’s oil and natural gas reserves and other factors.~~July 8, 2019. The borrowing base is scheduled to be re-determined semi-annually with effective dates of April 1st and October 1st. In addition, ~~Viper~~the Partnership may request up to three additional redeterminations of the borrowing base during any 12-month period. The credit agreement was further amended on May 22, 2015 to, among other things, increase the borrowing base from $110.0 million to $175.0 million and to provide for certain restrictions on purchasing margin stock. On November 13, 2015, the borrowing base was increased from $175.0 million to $200.0 million. As of March 31, ~~2016,~~2017, the borrowing base was set at ~~$200.0 million. The Partnership~~$275.0 million and Viper had ~~$43.0 million~~

no outstanding borrowings under its credit ~~agreement with a weighted average interest rate of 1.94%.~~agreement. In connection with the Partnership’s spring ~~2016~~2017 redetermination, the agent lender under the credit agreement has recommended that the Partnership’s borrowing base be ~~reduced~~increased to ~~$175.0 million due to a decline in pricing.~~$315.0 million. This ~~reduction~~increase is subject to the approval of the required other lenders.

The outstanding borrowings under Viper’s credit agreement bear interest at a rate elected by Viper that is equal to an alternative base rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.5% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable margin. The applicable margin ranges from ~~0.50%~~1.00% to ~~1.50%~~2.00% in the case of the alternative base rate and from ~~1.50%~~2.00% to ~~2.50%~~3.00% in the case of LIBOR, in each case depending on the amount of the loan outstanding in relation to the borrowing base. Viper is obligated to pay a quarterly commitment fee ranging from 0.375% to 0.500% per year on the unused portion of the borrowing base, which fee is also dependent on the amount of the loan outstanding in relation to the borrowing base. Loan principal may be optionally repaid from time to time without premium or penalty (other than customary LIBOR breakage), and is required to be repaid (a) to the extent that the loan amount exceeds the borrowing base, whether due to a borrowing base redetermination or otherwise (in some cases subject to a cure period) and (b) at the maturity date of July 8, 2019. The loan is secured by substantially all of the assets of Viper and its subsidiaries.



Financial Covenant	Required Ratio
Ratio of total debt to EBITDAX	Not greater than 4.0 to 1.0
Ratio of current assets to liabilities, as defined in the credit agreement	Not less than 1.0 to 1.0

The lenders may accelerate all of the indebtedness under Viper’s revolving credit facility upon the occurrence and during the continuance of any event of default. Viper’s credit agreement contains customary events of default, including non-payment, breach of covenants, materially incorrect representations, cross-default, bankruptcy and change of control. There are no cure periods for events of default due to non-payment of principal and breaches of negative and financial covenants, but non-payment of interest and breaches of certain affirmative covenants are subject to customary cure periods.

Capital Requirements and Sources of Liquidity

Our board of directors approved a ~~2016~~2017 capital budget for drilling and infrastructure of ~~$250.0~~approximately $800.0 million to ~~$375.0 million,~~$1.0 billion, representing ~~a decrease~~an increase of ~~26%~~132% over our ~~2015~~2016 capital budget. We estimate that, of these expenditures, approximately:

$~~210.0~~650.0 million to ~~$315.0~~$825.0 million will be spent on drilling and completing 30130 to 70165 gross ~~(25~~(110 to 58140 net) operated horizontal wells focused in the Midland ~~Andrews, Upton, Martin~~ and ~~Dawson Counties;~~Delaware Basins and participating in non-operated activity;

$~~25.0~~150.0 million to ~~$35.0~~$175.0 million will be spent on ~~infrastructure;~~infrastructure and other expenditures, excluding the cost of any leasehold and mineral interest acquisitions; and

$~~15.0~~75.0 million ~~to $25.0 million will be spent on non-operated activity and other expenditures.~~ in midstream assets.

During the three months ended March 31, ~~2016,~~2017, our aggregate capital expenditures for ~~drilling and infrastructure~~our development program were ~~$86.3~~$116.2 million. We do not have a specific acquisition budget since the timing and size of acquisitions cannot be accurately forecasted. During the three months ended March 31, ~~2016,~~2017, we spent approximately ~~$16.9 million~~$1.8 billion in cash on acquisitions of leasehold interests.

The amount and timing of these capital expenditures are largely discretionary and within our control. We could choose to defer a portion of these planned capital expenditures depending on a variety of factors, including but not limited to the success of our drilling activities, prevailing and anticipated prices for oil and natural gas, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other interest owners. With recent improvement in oil prices, we are currently operating eight rigs and three completion crews. We will continue monitoring

3743

improvement in oil prices, we have retained our third horizontal rig and are prepared to add a fourth horizontal rig early in the third quarter of 2016 in the event oil prices continue to strengthen. We will continue monitoring commodity prices and overall market conditions and can adjust our rig cadence up or down in response to changes in commodity prices and overall market conditions.

Based upon current oil and natural gas price and production expectations for ~~2016,~~2017, we believe that our cash flow from operations, cash on hand and borrowings under our revolving credit facility will be sufficient to fund our operations through year-end ~~2016.~~2017. However, future cash flows are subject to a number of variables, including the level of oil and natural gas production and prices, and significant additional capital expenditures will be required to more fully develop our properties. Further, our ~~2016~~2017 capital expenditure budget does not allocate any funds for leasehold interest and property acquisitions.

We monitor and adjust our projected capital expenditures in response to success or lack of success in drilling activities, changes in prices, availability of financing, drilling and acquisition costs, industry conditions, the timing of regulatory approvals, the availability of rigs, contractual obligations, internally generated cash flow and other factors both within and outside our control. If we require additional capital, we may seek such capital through traditional reserve base borrowings, joint venture partnerships, production payment financing, asset sales, offerings of debt and or equity securities or other means. We cannot assure you that the needed capital will be available on acceptable terms or at all. If we are unable to obtain funds when needed or on acceptable terms, we may be required to curtail our drilling programs, which could result in a loss of acreage through lease expirations. In addition, we may not be able to complete acquisitions that may be favorable to us or finance the capital expenditures necessary to replace our reserves. If there is further decline in commodity prices, our revenues, cash flows, results of operations, liquidity and reserves may be materially and adversely affected.

~~Security Ratings~~



	~~Moody's Investors Services~~	~~Standard & Poor's Ratings Services~~
~~Diamondback Senior Notes~~	B1	B+

Access to reasonably priced capital is dependent in part on credit and security ratings. Generally, lower ratings lead to higher financing costs. The impact of any future downgrade could include an increase in the costs of the Company's short- and long-term borrowings.

A security rating is not a recommendation to buy, sell or hold securities. Such rating may be subject to revision or withdrawal at any time by the credit rating agency and each rating should be evaluated independently of any other rating.

Contractual Obligations

Except as discussed in Note 1415 of the Notes to the Consolidated Financial Statements of this report, there were no material changes to our contractual obligations and other commitments, as disclosed in our Annual Report on Form 10-K for the year ended December 31, ~~2015.~~2016.

Critical Accounting Policies

There have been no changes in our critical accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, ~~2015.~~2016.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements as of March 31, ~~2016.~~2017. Please read Note 1415 included in Notes to the Combined Consolidated Financial Statements set forth in Part I, Item 1 of this report, for a discussion of our commitments and contingencies, some of which are not recognized in the balance sheets under GAAP.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk

Our major market risk exposure is in the pricing applicable to our oil and natural gas production. Realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot market prices applicable to our natural gas production. Pricing for oil and natural gas production has been volatile and unpredictable for several years, and we expect this volatility to continue in the future. The prices we receive for production depend on many factors outside of our control.

We use price swap derivatives, including basis swaps and costless collars, to reduce price volatility associated with certain of our oil sales. With respect to these fixed price swap contracts, the counterparty is required to make a payment to us if the settlement price for any settlement period is less than the swap price, and we are required to make a payment to the counterparty if the settlement price for any settlement period is greater than the swap price. Our derivative contracts are based upon reported settlement prices on commodity exchanges, with crude oil derivative settlements based on ~~New York Mercantile Exchange~~NYMEX West Texas Intermediate pricing.

At March 31, ~~2016,~~2017, we had a net asset derivative position of ~~$0.9~~$17.5 million ~~related to our price swap derivatives,~~ as compared to a net ~~asset~~liability derivative position of ~~$4.6~~$22.6 million ~~as of~~at December 31, ~~2015~~2016 related to our price swap derivatives. Utilizing actual derivative contractual volumes under our fixed price swaps as of March 31, ~~2016,~~2017, a 10% increase in forward curves

associated with the underlying commodity would have decreased the net asset position to a net liability position ~~to $4.6~~of $9.4 million, a decrease of ~~$5.6~~$26.9 million, while a 10% decrease in forward curves associated with the underlying commodity would have increased the net asset derivative position to ~~$6.5~~$44.4 million, an increase of ~~$5.6~~$26.9 million. However, any cash derivative gain or loss would be substantially offset by a decrease or increase, respectively, in the actual sales value of production covered by the derivative instrument.

Subsequent to March 31, 2016, we entered into additional commodity contracts, which consisted of fixed price oil swaps covering 184,000 Bbls of our production for the production period from July 1, 2016 to December 31, 2016 and 365,000 Bbls of our production for the production period from January 1, 2017 to December 31, 2017. These fixed price oil swaps will settle against the weighted average price per barrel of NYMEX West Texas Intermediate during the calculation periods.

Counterparty and Customer Credit Risk

Our principal exposures to credit risk are through receivables resulting from joint interest receivables (approximately ~~$15.2~~$56.0 million at March 31, ~~2016)~~2017) and receivables from the sale of our oil and natural gas production (approximately ~~$33.9~~$83.5 million at March 31, ~~2016)~~2017).

We are subject to credit risk due to the concentration of our oil and natural gas receivables with several significant customers. We do not require our customers to post collateral, and the inability of our significant customers to meet their obligations to us or their insolvency or liquidation may adversely affect our financial results. For the three months ended March 31, 2017, three purchasers each accounted for more than 10% of our revenue: Shell Trading (US) Company (42%); Koch Supply & Trading LP (18%); and Enterprise Crude Oil LLC (14%). For the three months ended March 31, 2016, two purchasers each accounted for more than 10% of our revenue: Shell Trading (US) Company (57%); and Enterprise Crude Oil LLC (14%~~). For the year ended three months ended March 31, 2015, two purchasers each accounted for more than 10% of our revenue: Shell Trading (US) Company (68%); and Enterprise Crude Oil LLC (11%~~). No other customer accounted for more than 10% of our revenue during these periods.

Joint operations receivables arise from billings to entities that own partial interests in the wells we operate. These entities participate in our wells primarily based on their ownership in leases on which we intend to drill. We have little ability to control whether these entities will participate in our wells. At March 31, ~~2016,~~2017, we had two customers that represented approximately ~~72%~~65% of our total joint operations receivables. At December 31, ~~2015,~~2016, we had ~~five customer~~three customers that represented approximately ~~73%~~75% of our total joint operations receivables.

Interest Rate Risk

We are subject to market risk exposure related to changes in interest rates on our indebtedness under our revolving credit facility. The terms of our revolving credit facility provide for interest on borrowings at a floating rate equal to an alternative base rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.5% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable margin. The applicable margin ranges

from 0.50% to 1.50% in the case of the alternative base rate and from 1.50% to 2.50% in the case of LIBOR, in each case depending on the amount of the loan outstanding in relation to the borrowing base.

As of March 31, ~~2016,~~2017, we had no borrowings outstanding under our revolving credit facility. Our weighted average interest rate on borrowings under our revolving credit facility was 1.92% on January 19, 2016, the last day on which borrowings were outstanding under such facility. An increase or decrease of 1% in the interest rate would have a corresponding decrease or increase in our interest expense of approximately $0.1 million based on the $11.0 million outstanding in the aggregate under our revolving credit facility as of such date.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Control and Procedures

Under the direction of our Chief Executive Officer and Chief Financial Officer, we have established disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The disclosure controls and procedures are also intended to ensure that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

As of March 31, ~~2016,~~2017, an evaluation was performed under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Exchange Act. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of March 31, ~~2016,~~2017, our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There have not been any changes in our internal control over financial reporting that occurred during the quarter ended March 31, ~~2016~~2017 that have materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.

PART II

ITEM 1. LEGAL PROCEEDINGS

Due to the nature of our business, we are, from time to time, involved in routine litigation or subject to disputes or claims related to our business activities, including workers’ compensation claims and employment related disputes. In the opinion of our management, none of the pending litigation, disputes or claims against us, if decided adversely, will have a material adverse effect on our financial condition, cash flows or results of operations.

ITEM 1A. RISK FACTORS

Our business faces many risks. Any of the risks discussed in this Form 10-Q and our other SEC filings could have a material impact on our business, financial position or results of operations. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also materially impair our business operations, financial condition or future results.

In addition to the information set forth in this report, you should carefully consider the risk factors discussed in Part I, Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, ~~2015.~~2016. There have been no material changes in our risk factors from those described in our Annual Report on Form 10-K for the year ended December 31, ~~2015.~~2016.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On February 28, 2017, we completed our acquisition of certain assets from Brigham Resources Operating, LLC and Brigham Resources Midstream, LLC, unrelated third-party sellers, under our previously reported purchase and sale agreement with the sellers dated as of December 13, 2016, as amended. The aggregate consideration for the acquisition was approximately $2.55 billion, consisting of $1.74 billion in cash and the issuance of 7.69 million shares of our common stock, par value $0.01 per share (of which approximately 1.15 million shares were placed in an indemnity escrow), subject to certain adjustments. These shares were issued in reliance upon the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) of the Securities Act, as sales by an issuer not involving any public offering.
