      “Diamondback continued to build on its execution track record in the second quarter. The Company  generated a record $1.3 billion in Free Cash Flow, exceeding last quarter’s prior Company record by 35%.  We used the cash to reduce our net debt by 5% quarter over quarter, pay a total dividend of $3.05 per share  and buy back over 2.3 million shares,” stated Travis Stice, Chairman and Chief Executive Officer of  Diamondback. “We continue to focus on operational excellence and cost control in this inflationary  operating environment, working to mitigate and offset the persistent inflationary pressures we are seeing  across our business. Diamondback has a strong track record of cost control, and we expect to continue to  improve on this track record in the coming quarters.”    Mr. Stice continued, “Beginning this quarter, we have committed to return a minimum of 75% of our Free  Cash Flow to stockholders, which places Diamondback’s cash returns framework at the forefront of the  industry. We believe this combination of execution, cost control and cash returns presents a differentiated  value proposition to our stockholders that is not reflected in today’s equity value, which is why our Board   approved a $2.0 billion increase to our share repurchase authorization to $4.0 billion.”    OPERATIONS UPDATE    The tables below provide a summary of operating activity for the second quarter of 2022.

Forward-Looking Statements    This news release contains “forward-looking statements” within the meaning of Section 27A of the  Securities Act and Section 21E of the Exchange Act, which involve risks, uncertainties, and assumptions.  All statements, other than statements of historical fact, including statements regarding Diamondback’s:  future performance; business strategy; future operations (including drilling plans and capital plans);  estimates and projections of revenues, losses, costs, expenses, returns, cash flow, and financial position;  reserve estimates and its ability to replace or increase reserves; anticipated benefits of strategic  transactions (including acquisitions and divestitures); and plans and objectives of management (including  plans for future cash flow from operations and for executing environmental strategies) are forward- looking statements. When used in this news release, the words “aim,” “anticipate,” “believe,” “continue,”  “could,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “model,” “outlook,”  “plan,” “positioned,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” and  similar expressions (including the negative of such terms) as they relate to Diamondback are intended to  identify forward-looking statements, although not all forward-looking statements contain such identifying  words. Although Diamondback believes that the expectations and assumptions reflected in its forward- looking statements are reasonable as and when made, they involve risks and uncertainties that are difficult  to predict and, in many cases, beyond Diamondback’s control. Accordingly, forward-looking statements  are not guarantees of future performance and Diamondback’s actual outcomes could differ materially from  what Diamondback has expressed in its forward-looking statements.    Factors that could cause the outcomes to differ materially include (but are not limited to) the following:  changes in supply and demand levels for oil, natural gas, and natural gas liquids, and the resulting impact  on the price for those commodities; the impact of public health crises, including epidemic or pandemic  diseases such as the COVID-19 pandemic, and any related company or government policies or actions;  actions taken by the members of OPEC and Russia affecting the production and pricing of oil, as well as  other domestic and global political, economic, or diplomatic developments, including any impact of the  ongoing war in Ukraine on the global energy markets and geopolitical stability; inflationary pressures;  rising interest rates and their impact on the cost of capital; regional supply and demand factors, including  delays, curtailment delays or interruptions of production, or governmental orders, rules or regulations that  impose production limits; federal and state legislative and regulatory initiatives relating to hydraulic  fracturing, including the effect of existing and future laws and governmental regulations; transition risks  relating to climate change and the risks and other factors disclosed in Diamondback’s filings with the  Securities and Exchange Commission, including its Forms 10-K, 10-Q and 8-K, which can be obtained  free of charge on the Securities and Exchange Commission’s web site at http://www.sec.gov.    
 
 
 
    In light of these factors, the events anticipated by Diamondback’s forward-looking statements may not  occur at the time anticipated or at all. Moreover, Diamondback operates in a very competitive and rapidly  changing environment and new risks emerge from time to time. Diamondback cannot predict all risks, nor  can it assess the impact of all factors on its business or the extent to which any factor, or combination of  factors, may cause actual results to differ materially from those anticipated by any forward-looking  statements it may make. Accordingly, you should not place undue reliance on any forward-looking  statements made in this news release. All forward-looking statements speak only as of the date of this  news release or, if earlier, as of the date they were made. Diamondback does not intend to, and disclaims  any obligation to, update or revise any forward-looking statements unless required by applicable law.

    NON-GAAP FINANCIAL MEASURES    ADJUSTED EBITDA    Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and  external users of our financial statements, such as industry analysts, investors, lenders and rating agencies.  The Company defines Adjusted EBITDA as net income (loss) attributable to Diamondback Energy, Inc.,  plus net income (loss) attributable to non-controlling interest ("net income (loss)") before non-cash (gain)  loss on derivative instruments, net, interest expense, net, depreciation, depletion, amortization and  accretion, depreciation and interest expense related to equity method investments, impairment and  abandonments related to equity method investments, (gain) loss on sale of equity method investments,  (gain) loss on extinguishment of debt, non-cash equity-based compensation expense, capitalized equity- based compensation expense, merger and integration expense, other non-cash transactions and provision  for (benefit from) income taxes, if any. Adjusted EBITDA is not a measure of net income as determined  by United States generally accepted accounting principles ("GAAP"). Management believes Adjusted  EBITDA is useful because the measure allows it to more effectively evaluate the Company’s operating  performance and compare the results of its operations from period to period without regard to its financing  methods or capital structure. The Company adds the items listed above to net income (loss) to determine  Adjusted EBITDA because these amounts can vary substantially from company to company within its  industry depending upon accounting methods and book values of assets, capital structures and the method  by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or  more meaningful than, net income as determined in accordance with GAAP or as an indicator of the  Company’s operating performance or liquidity. Certain items excluded from Adjusted EBITDA are  significant components in understanding and assessing a company’s financial performance, such as a  company’s cost of capital and tax structure, as well as the historic costs of depreciable assets. The  Company’s computation of Adjusted EBITDA may not be comparable to other similarly titled measures of  other companies or to such measure in our credit facility or any of our other contracts.

    ADJUSTED NET INCOME  Adjusted net income is a non-GAAP financial measure equal to net income (loss) attributable to  Diamondback Energy, Inc. plus net income (loss) attributable to non-controlling interest ("net income  (loss)") adjusted for non-cash (gain) loss on derivative instruments, net, (gain) loss on sale of property,  plant and equipment, impairment and abandonments related to equity method investments, (gain) loss on  extinguishment of debt, other non-cash transactions and related income tax adjustments, if any. The  Company’s computation of adjusted net income may not be comparable to other similarly titled measures  of other companies or to such measure in our credit facility or any of our other contracts. Management  believes Adjusted Net Income helps investors in the oil and natural gas industry to measure and compare  the Company's performance to other oil and natural gas companies by excluding from the calculation  items that can vary significantly from company to company depending upon accounting methods, the  book value of assets and other non-operational factors.  The following table presents a reconciliation of the GAAP financial measure of net income (loss)  attributable to Diamondback Energy, Inc. to the non-GAAP measure of adjusted net income:  Diamondback Energy, Inc.

The two-class method is an earnings allocation which reflects the respective ownership among holders of common  stock and participating securities. Diluted earnings per share using the two-class method is calculated as (i) net income  attributable to Diamondback Energy, Inc, (ii) plus the reallocation of $13 million in earnings attributable to participating  securities, divided by (iii) diluted weighted average common shares outstanding.       
 
 
 
    OPERATING CASH FLOW BEFORE WORKING CAPITAL CHANGES, FREE CASH FLOW  AND ADJUSTED FREE CASH FLOW    Operating cash flow before working capital changes, which is a non-GAAP financial measure representing  net cash provided by operating activities as determined under GAAP without regard to changes in  operating assets and liabilities. The Company believes operating cash flow before working capital changes  is a useful measure of an oil and natural gas company’s ability to generate cash used to fund exploration,  development and acquisition activities and service debt or pay dividends. The Company also uses this  measure because adjusted operating cash flow relates to the timing of cash receipts and disbursements that  the Company may not control and may not relate to the period in which the operating activities occurred.  This allows the Company to compare its operating performance with that of other companies without  regard to financing methods and capital structure.     Free Cash Flow, which is a non-GAAP financial measure, is cash flow from operating activities before  changes in working capital in excess of cash capital expenditures. Adjusted Free Cash Flow, which is a  non-GAAP financial measure, is Free Cash Flow adjusted for early termination of commodity derivative  contracts. The Company believes that Free Cash Flow and Adjusted Free Cash Flow are useful to  investors as they provide measures to compare both cash flow from operating activities and additions to  oil and natural gas properties across periods on a consistent basis as adjusted for non-recurring early  settlements of commodity derivative contracts. These measures should not be considered as an alternative  to, or more meaningful than, net cash provided by operating activities as an indicator of operating  performance. The Company's computation of operating cash flow before working capital changes, Free  Cash Flow and Adjusted Free Cash Flow may not be comparable to other similarly titled measures of  other companies. The Company uses Free Cash Flow to reduce debt, as well as return capital to  stockholders as determined by the Board of Directors.

    NET DEBT    The Company defines net debt as total debt less cash and cash equivalents. Net debt should not be  considered an alternative to, or more meaningful than, total debt, the most directly comparable GAAP  measure. Management uses net debt to determine the Company's outstanding debt obligations that would  not be readily satisfied by its cash and cash equivalents on hand. The Company believes this metric is  useful to analysts and investors in determining the Company's leverage position because the Company has  the ability to, and may decide to, use a portion of its cash and cash equivalents to reduce debt.
