FIRST QUARTER 2021 HIGHLIGHTS

• Previously announced Q1 2021 average production of 184.2 MBO/d (307.4 MBOE/d)
• Generated Q1 2021 cash flow from operating activities of $624 million. Operating Cash Flow Before Working Capital Changes (as defined and reconciled below) of $627 million
• Q1 2021 cash capital expenditures of $296 million; Q1 2021 activity-based capital expenditures incurred of approximately $267 million
• Generated Q1 2021 Free Cash Flow (as defined and reconciled below) of $331 million
• Q1 2021 cash operating costs of $8.06 per BOE; including cash general and administrative ("G&A") expenses of $0.54 per BOE and lease operating expenses ("LOE") of $3.69 per BOE
• Closed the previously announced acquisition of assets from Guidon Operating LLC ("Guidon") and the acquisition of QEP Resources, Inc. ("QEP") in an all stock merger, adding an aggregate of over 80,000 net acres to our asset base in the Permian Basin and generating significant synergies
• Signed definitive agreements in the second quarter of 2021 to divest Williston Basin assets acquired in the merger with QEP and non-core Permian Basin assets for total consideration of $832 million, subject to certain closing adjustments; assets being sold have estimated full year 2021 net production of approximately 16 MBO/d (28 MBOE/d)
• Flared 0.75% (1.0% including QEP) of gross natural gas production in the first quarter of 2021
• Received $103 million federal net operating loss carryback and alternative minimum tax credit refund in January 2021, which included $3 million of interest income
• Initiating Q2 2021 production guidance of 232.0 - 236.0 MBO/d (387.0 - 394.0 MBOE/d) and cash capex guidance of $350 - $400 million

“Diamondback started 2021 with a successful first quarter, effectively overcoming the production obstacles presented by Winter Storm Uri while keeping our capital and operating costs near all-time lows. As a result, we generated over $330 million of Free Cash Flow in the first quarter. At current strip pricing, and pro forma for our asset sales announced today, we expect to continue generating significant Free Cash Flow in 2021. This Free Cash Flow, coupled with the cash proceeds from the successful execution of our three non-core asset sales announced today, will allow us to accelerate our debt reduction program, further strengthening our balance sheet," stated Travis Stice, Chief Executive Officer of Diamondback.

Mr. Stice continued, “We continue to be pleased with the seamless integration of both the Guidon and QEP assets, and we are achieving our synergy targets ahead of schedule and in excess of those highlighted during the acquisition announcement. This progress only adds to our 'exploit and return' strategy of spending maintenance capital to hold oil production flat, while using Free Cash Flow to reduce debt and return cash to stockholders."

NON-GAAP FINANCIAL MEASURES

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 revaluation of investment, loss on extinguishment of debt, impairment of oil and natural gas properties, impairment of midstream assets, 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) in arriving at 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.

The following tables present a reconciliation of the GAAP financial measure of net income (loss) attributable to Diamondback Energy, Inc. to the non-GAAP financial measure of Adjusted EBITDA:

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, impairment and abandonments related to equity method investments, loss on extinguishment of debt, impairment of midstream assets, merger and integration expense 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.

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 an accepted 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.

Additionally, the Company provides Free Cash Flow, which is a non-GAAP financial measure. Free Cash Flow is cash flow from operating activities before changes in working capital in excess of cash capital expenditures. The Company believes that Free Cash Flow is useful to investors as it provides a measure to compare both cash flow from operating activities and additions to oil and natural gas properties across periods on a consistent basis. 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 and Free Cash Flow may not be comparable to other similarly titled measures of other companies.

The following tables present a reconciliation of net cash provided by operating activities to operating cash flow before working capital changes and to Free Cash Flow:

RECONCILIATION OF TOTAL DEBT TO 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.
