Mach Natural Resources LP Announces Third-Quarter 2023 Financial and Operating Results

OKLAHOMA CITY, Oklahoma, December 6, 2023 — Mach Natural Resources LP (NYSE: MNR) (“Mach” or the “Company”) today reported financial and operating results for the three and nine months ended September 30, 2023, and additional Company updates.

Key Updates

The highlights presented below reflect select financial metrics of our predecessor BCE-Mach III LLC.  The unaudited financial statements of our predecessor BCE-Mach III LLC are presented in their entirety in the appendix of this release. The business combination that resulted in our 100% ownership of BCE-Mach LLC, BCE-Mach II LLC and BCE-Mach III LLC occurred at the time of the IPO and the corporate reorganization and as a result was after the end of the third quarter and not reflected in the Form 10-Q.

BCE-Mach III LLC Financial and Operational Highlights

To facilitate a clearer representation of our third-quarter 2023 performance, all results presented hereinafter are on a pro forma basis to reflect the combined results of each of these three entities. 

Pro Forma Financial and Operational Highlights

Reflecting on the quarter, Mach’s Chief Executive Officer, Tom L. Ward, commented, “In the third quarter, we generated strong cash flow from better-than-expected production volumes while controlling costs across all areas of our business. Additionally, our strong results for the quarter were achieved while keeping our reinvestment rate below 50%. As we look ahead, our focus will remain the same—execute on our operations so that we can continue to deliver robust distributions to our unitholders.”

Pro Forma Third-Quarter 2023 Operational Results

Mach’s sales volumes during the quarter averaged 66,280 Boe per day, which consisted of 28% oil, 54% natural gas and 18% natural gas liquids (“NGLs”).

Also during the third quarter, the Company spud 20 gross (15 net) wells and brought online 20 gross (16 net) wells. As of September 30, 2023, the Company had 6 gross (4 net) wells in various stages of drilling and completion. 

Pro Forma Third-Quarter 2023 Financial Results

Mach reported net income of $94 million for the third quarter of 2023 and Adjusted EBITDA of $140 million.

For the third quarter of 2023, the average realized price was $80.88 per barrel of crude oil, $23.47 per barrel of NGLs and $2.36 per Mcf of natural gas.

Paloma Acquisition Update

Mach’s recently announced acquisition from Paloma (the “Paloma Acquisition”) is expected to close on December 29, 2023, adding 75 million Boe of proved developed producing (“PDP”) reserves, greater than 12 years of drilling inventory, and recent production of approximately 32,000 Boe per day.

“Our most recent acquisition from Paloma is accretive to both total cash available for distribution, as well as expected cash distribution per unit. This fits with the stated objectives of our Company:

(1) maximize distributions;

(2) disciplined acquisitions focused on accretion to distribution;

(3) maintain low leverage; and

(4) strategic reinvestment rate to optimize distributions.

Looking ahead, we will continue to act swiftly when the right opportunity arises, while assuring that Mach’s commitment to maximizing cash distributions to unitholders is upheld,” commented Tom L. Ward, Mach’s Chief Executive Officer.

In anticipation of the transaction, the Company has actively been adding to its existing hedges with the expectation that 2024 and 2025 PDP oil and natural gas production will be 50% and 25% hedged, respectively, by closing of the Paloma Acquisition.

Distributions

The Company’s first quarterly cash distribution as a public company is expected to be announced mid-February of 2024. The first quarterly cash distribution will be based on the results from the fourth quarter of 2023 and is expected to be distributed to unitholders in mid-March of 2024. Subsequent quarterly cash distributions will include incremental cash flow generated from the announced Paloma Acquisition.

2024 Guidance

Mach plans to provide full-year 2024 guidance in February of 2024.

Non-GAAP Measures

This release includes non-GAAP financial measures. Such non-GAAP measures are not alternatives to GAAP measures. These non-GAAP measures should not be considered in isolation or as a substitute for analysis of results as reported under GAAP.

Adjusted EBITDA

We include in this release 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 measures calculated and presented in accordance with GAAP. We define Adjusted EBITDA as net income before (1) interest expense and interest income, (2) depreciation, depletion, amortization and accretion, (3) unrealized (gain) loss on derivative settlements, (4) equity-based compensation expense, and (5) (gain) loss on sale of assets.

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 Available for Distribution

Cash available for distribution is not a measure of net income or net cash flow provided by or used in operating activities as determined by GAAP. Cash available for distribution is a supplemental non-GAAP financial performance measure used by our management and by external users of our financial statements, such as industry analysts, investors, lenders, rating agencies and others, to assess our ability to internally fund our exploration and development activities, pay distributions, and to service or incur additional debt. We define cash available for distribution as net income less (1) interest expense and interest income, (2) depreciation, depletion, amortization and accretion, (3) unrealized (gain) loss on derivative settlements, (4) equity-based compensation expense, (5) (gain) loss on sale of assets, (6) settlement of asset retirement obligations, (7) cash interest expense and cash interest income, (8) development costs and (9) change in accrued realized derivative settlements. Development costs include all of our capital expenditures, other than acquisitions. Cash available for distribution will not reflect changes in working capital balances. Cash available for distribution is not a measurement of our financial performance or liquidity under GAAP and should not be considered as an alternative to, or more meaningful than, net income or net cash provided by or used in operating activities as determined in accordance with GAAP or as indicators of our financial performance and liquidity. The GAAP measures most directly comparable to cash available for distribution are net income and net cash provided by operating activities. Cash available for distribution should not be considered as an alternative to, or more meaningful than, net income or net cash provided by operating activities.
