OKLAHOMA CITY, Oklahoma, May 7, 2026 — Mach Natural Resources LP (NYSE: MNR) ("Mach" or the "Company") today reported financial and operating results for the three months ended March 31, 2026. The Company also announced its quarterly cash distribution.

"Mach is off to a strong start in 2026, executing at a high level and delivering results in line with our plan," said Tom L. Ward, Chief Executive Officer. "Our first quarter distribution of $0.64 per common unit reflects our continued ability to generate and deliver attractive unitholder returns while upholding our measured reinvestment approach."

Tom L. Ward continued, "During the quarter, we began shifting our drilling program toward oil, demonstrating the optionality of our asset base and the flexibility of our operations. As we move through the year, we will remain nimble and disciplined, allocating capital to highest-return opportunities and staying aligned with our core objective of maximizing distributions."

<sup>1</sup> Adjusted EBITDA is a non-GAAP financial measure.

**Non-GAAP Financial Measures and Disclosures**

This press release includes non-GAAP financial measures. Pursuant to regulatory disclosure requirements, Mach is required to reconcile non-GAAP financial measures to the related GAAP information. Reconciliations of these non-GAAP measures are provided below. Reconciliations of these non-GAAP measures, along with other financial and operational disclosures, are also within the supplemental tables that are available on the Company's website at www.machnr.com and in the related Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (the "SEC").

***Adjusted EBITDA<sup>(1)</sup>***

We include in this Quarterly Report the supplemental non-GAAP financial performance measure Adjusted EBITDA and provide our calculation of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income, our most directly comparable financial measure calculated and presented in accordance with GAAP. We define Adjusted EBITDA as net income before (1) interest expense, net, (2) depreciation, depletion, amortization and accretion, (3) unrealized (gain) loss on derivative instruments, (4) loss on debt extinguishment, (5) equity-based compensation expense and (6) loss (gain) on sale of assets, net.

Adjusted EBITDA is used as a supplemental financial performance measure by our management and by external users of our financial statements, such as industry analysts, investors, lenders, rating agencies and others, to more effectively evaluate our operating performance and our results of operation from period to period and against our peers without regard to financing methods, capital structure or historical cost basis. We exclude the items listed above from net income in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA is not a measurement of our financial performance under GAAP and should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as indicators of our operating performance. 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 burden, as well as the historic costs of depreciable assets, none of which are reflected in Adjusted EBITDA. Our presentation of Adjusted EBITDA should not be construed as an inference that our results will be unaffected by unusual items. Our computations of Adjusted EBITDA may not be identical to other similarly titled measures of other companies.
