¹Adjusted EBITDA is a non-GAAP measure. Mach has defined this measure and provided reconciliations of this non-GAAP measure to its most directly comparable financial measure calculated and presented in accordance with U.S. generally accepted accounting principles ("GAAP") at the conclusion of this press release under "Non-GAAP Financial Measures and Disclosures."

²CROCI is a non-GAAP financial measure. For more information on CROCI, see "Non-GAAP Financial Measures and Disclosures" at the conclusion of this press release.

³PV-10 is a non-GAAP financial measure and represents the present value of estimated future cash inflows from proved oil and gas reserves, less future development and production costs, discounted at 10% per annum to reflect the timing of future cash flows. For more information on how we calculate PV-10 and a reconciliation of proved reserves PV-10 to its nearest GAAP measure, see "Non-GAAP Financial Measures and Disclosures" at the conclusion of this press release.

⁴Mach's estimated net proved reserves were determined using average first-day-of-the-month prices for the prior 12 months in accordance with SEC regulations. The unweighted arithmetic average first-day-of-the-month prices for the prior 12 months were $65.34 per barrel for oil and $3.39 per MMBtu for natural gas at December 31, 2025. These base prices were adjusted for differentials on a per-property basis, which may include local basis differentials, fuel costs and shrinkage.

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 (GAAP refers to generally accepted accounting principles). 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 Form 10-K filed with the SEC.

Adjusted EBITDA⁽¹⁾Mach includes in this press release the supplemental non-GAAP financial performance measure Adjusted EBITDA and provides the Company's calculation of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income, the Company's most directly comparable financial measure calculated and presented in accordance with GAAP. The Company defines Adjusted EBITDA as net income before (1) interest expense, net, (2) depreciation, depletion, amortization and accretion, (3) unrealized (gain) loss on derivative instruments, (4) impairment on oil and gas assets, (5) loss on debt extinguishment, (6) equity-based compensation expense and (7) 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.

Cash Return on Capital Invested ("CROCI") ⁽²⁾CROCI is defined as cash flow from operations plus interest expense, divided by the average of both the prior and current year's total current assets less cash and cash equivalents less total current liabilities plus the current portion of long-term debt plus proved oil and natural gas properties plus other property, plant and equipment plus other assets. CROCI is presented based on our management's belief that this non-GAAP measure is useful information to investors when evaluating our profitability and the efficiency with which management has employed capital over time. CROCI is not a measure of financial performance under GAAP and should not be considered an alternative to net income, as defined by GAAP.

PV-10 and Standardized Measure ⁽³⁾Certain of our oil and natural gas reserve disclosures included in this Annual Report are presented on a PV-10 basis. PV-10 is a non-GAAP financial measure and represents the estimated present value of the future cash flows less future development and production costs from our proved reserves before income taxes, discounted using a 10% discount rate. PV-10 of proved reserves generally differs from the standardized measure of discounted future net cash flows from production of proved oil and natural gas reserves (the "Standardized Measure"), the most directly comparable GAAP financial measure, because it does not include the effects of future income taxes, as is required under GAAP in computing the Standardized Measure. The Company is a limited partnership treated as a partnership for federal and state income tax purposes, and accordingly is not subject to entity level taxation. However, the Company does pay franchise taxes in the state of Texas, which are represented as income taxes in the calculation of the Company's Standardized Measure. The impact of these taxes was approximately $18 million.

We believe that the presentation of a pre-tax PV-10 value provides relevant and useful information because it is widely used by investors and analysts as a basis for comparing the relative size and value of our proved reserves to other oil and natural gas companies. Because many factors that are unique to each individual company may impact the amount and timing of future income taxes, the use of PV-10 value provides greater comparability when evaluating oil and natural gas companies. The PV-10 value is not a measure of financial or operating performance under GAAP, nor is it intended to represent the current market value of proved oil and gas reserves. However, the definition of PV-10 value as defined above may differ significantly from the definitions used by other companies to compute similar measures. As a result, the PV-10 value as defined may not be comparable to similar measures provided by other companies.

Investors should be cautioned that neither PV-10 nor Standardized Measure of proved reserves represents an estimate of the fair market value of our proved reserves. We and others in the industry use PV-10 as a measure to compare the relative size and value of estimated reserves held by companies without regard to the specific tax characteristics of such entities.
