“Completion.” The process of treating a drilled well followed by the installation of permanent equipment for the production of natural gas or oil, or in the case of a dry hole, the reporting of abandonment to the appropriate agency.

“Developed oil and gas reserves.” Developed oil and gas reserves are reserves of any category that can be expected to be recovered: (i) through existing wells with existing equipment and operating methods or in which the cost of the related equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

“Field.” An area consisting of a single reservoir or multiple reservoirs all grouped on, or related to, the same individual geological structural feature or stratigraphic condition. The field name refers to the surface area, although it may refer to both the surface and the underground productive formations. For a complete definition of field, refer to the SEC’s Regulation S-X, Rule 4-10(a)(15).

“Formation.” A layer of rock which has distinct characteristics that differs from nearby rock.

“Holdco.” Mach Natural Resources Holdco LLC, a Delaware limited liability company.

Table of Contents

“MMcf.” One million cubic feet of natural gas.

“MMcf/d.” One million cubic feet of natural gas per day.

“NGLs.” Hydrocarbons found in natural gas which may be extracted as liquefied petroleum gas and natural gasoline.

“Net wells.” The percentage of gross wells an owner has. An owner who has a 50% interest in 100 gross wells owns 50 net wells.

“New Revolving Credit Facility.” Refers to the senior secured revolving credit agreement, dated as of February 27, 2025, among the Company, the lenders party thereto, and Truist Bank as administrative agent.

“NYMEX.” The New York Mercantile Exchange.

“OPEC +.” Organization of the Petroleum Exporting Countries.

“Partnership agreement.” The Amended and Restated Agreement of Limited Partnership of Mach Natural Resources LP.

“Proved reserves.” Proved oil and natural gas reserves are those quantities of oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible — from a given date forward from known reservoirs, and under existing economic conditions, operating methods and government regulations — prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. For a complete definition of proved crude oil and natural gas reserves, refer to the SEC’s Regulation S-X, Rule 4-10(a)(22).

“Proved undeveloped reserves (“PUD”).” Proved reserves that are expected to be recovered from new wells on undrilled acreage or from existing wells where a relatively major expenditure is required for recompletion. Undrilled locations can be classified as having proved undeveloped reserves only if a development plan has been adopted indicating that such locations are scheduled to be drilled within five years unless specific circumstances justify a longer time.

“PV-10.” When used with respect to oil and natural gas reserves, PV-10 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. Calculation of PV-10 does not give effect to derivatives transactions. Our PV-10 has historically been computed on the same basis as our Standardized Measure, the most comparable measure under GAAP. PV-10 is not a financial measure calculated or presented in accordance with GAAP and generally differs from Standardized Measure, the most directly comparable GAAP financial measure, because it does not include the effects of either well abandonment costs or income taxes on future net revenues. Neither PV-10 nor Standardized Measure represents an estimate of the fair market value of our oil and natural gas properties. We and others in the industry use PV-10 as a measure to compare the relative size and value of proved reserves held by companies without regard to the specific tax characteristics of such entities.

“Recompletion.” The process of re-entering an existing wellbore that is either producing or not producing and completing reservoirs in an attempt to establish or increase existing production.

“Reservoir.” A porous and permeable underground formation containing a natural accumulation of producible oil and/or natural gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs.

“Revolving Credit Agreement.” Refers to the senior secured revolving credit agreement, dated as of December 28, 2023, among the Company, the lenders party thereto, and MidFirst Bank as administrative agent.

“Standardized Measure.” Standardized Measure is our standardized measure of discounted future net cash flows, which is prepared using assumptions required by the Financial Accounting Standards Board. Such assumptions include the use of 12-month average prices for oil and gas, based on the first-day-of-the-month price for each month in the period, and year end costs for estimated future development and production expenditures to produce year-end estimated proved reserves. Discounted future net cash flows are calculated using a 10% rate. No provision is included for federal income taxes since our future net cash flows are not subject to taxation. However, our operations are subject to the Texas franchise tax. Estimated well abandonment costs, net of salvage values, are deducted from the standardized measure using year-end costs and discounted at the 10% rate. The standardized measure does not represent management’s estimate of our future cash flows or the value of proved oil and natural gas reserves. Probable and possible reserves, which may become proved in the future, are excluded from the calculations. Furthermore, prices used to determine the standardized measure are influenced

by supply and demand as effected by recent economic conditions as well as other factors and may not be the most representative in estimating future revenues or reserve data.

“Term Loan Credit Agreement.” Refers to the senior secured term loan credit agreement, dated as of December 28, 2023, among the Company, the lenders party thereto, Texas Capital Bank, as agent, and Chambers Energy Management, LP, as the arranger.

“Wellbore.” The hole drilled by the bit that is equipped for oil and natural gas production on a completed well. Also called well or borehole.

“Working interest.” The right granted to the lessee of a property to explore for and to produce and own oil and natural gas or other minerals. The working interest owners bear the exploration, development, and operating costs on either a cash, penalty, or carried basis.

“Workover.” Operations on a producing well to restore or increase production.

“WTI.” West Texas Intermediate.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

The information in this Quarterly Report on Form 10-Q contains or incorporates by reference information that includes or is based upon “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements, other than statements of historical fact included in this Quarterly Report regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this Quarterly Report, words such as “may,” “assume,” “forecast,” “could,” “should,” “will,” “plan,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” “budget” and similar expressions are used to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events at the time such statement was made. When considering forward-looking statements, you should keep in mind the risk factors included in Part I, Item 1A. “Risk Factors” and Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2024 and elsewhere in this Quarterly Report. All forward-looking statements speak only as of the date of this Quarterly Report.

Forward-looking statements may include statements about:

•our business strategy;

•our estimated proved reserves;

•our ability to distribute cash available for distribution and achieve or maintain certain financial and operational metrics;

•our drilling prospects, inventories, projects and programs;

•general economic conditions;

•actions taken by OPEC + as it pertains to the global supply and demand of, and prices for, oil, natural gas and NGLs;

•our ability to replace the reserves we produce through drilling and property acquisitions;

•our financial strategy, leverage, liquidity and capital required for our development program;

•our pending legal or environmental matters;

•our realized oil and natural gas prices;

•the timing and amount of our future production of natural gas;

•our hedging strategy and results;

•our competition and government regulations;

•our ability to obtain permits and governmental approvals;

•our marketing of natural gas;

•our leasehold or business acquisitions;

•our costs of developing our properties;

•credit markets;

•our decline rates of our oil and natural gas properties;

•uncertainty regarding our future operating results; and

•our plans, objectives, expectations and intentions contained in this Quarterly Report that are not historical.

We caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond our control, incident to the exploration for and development and production of oil, natural gas and NGL. We disclose important factors that could cause our actual results to differ materially from our expectations as described under “Risk Factors” included in Part I, Item 1A in our Annual Report for the year ended December 31, 2024. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include:

•commodity price volatility;

v

Table of Contents

•the impact of epidemics, outbreaks or other public health events, and the related effects on financial markets, worldwide economic activity and our operations;

•uncertainties about our estimated oil, natural gas and NGL reserves, including the impact of commodity price declines on the economic producibility of such reserves, and in projecting future rates of production;

•the concentration of our operations in the Anadarko Basin;

•difficult and adverse conditions in the domestic and global capital and credit markets;

•lack of transportation and storage capacity as a result of oversupply, government regulations or other factors;

•lack of availability of drilling and production equipment and services;

•potential financial losses or earnings reductions resulting from our commodity price risk management program or any inability to manage our commodity risks;

•failure to realize expected value creation from property acquisitions and trades;

•access to capital and the timing of development expenditures;

•environmental, weather, drilling and other operating risks;

•regulatory changes, including potential shut-ins or production curtailments mandated by the Railroad Commission of Texas, the Oklahoma Corporation Commission and/or the Kansas Corporation Commission;

•competition in the oil and natural gas industry;

•loss of production and leasehold rights due to mechanical failure or depletion of wells and our inability to re-establish their production;

•our ability to service our indebtedness;

•any downgrades in our credit ratings that could negatively impact our cost of and ability to access capital;

•cost inflation;

•the potential for significant new tariffs and their impact on global oil, natural gas and NGL markets;

•political and economic conditions and events in foreign oil and natural gas producing countries, including embargoes, continued hostilities in the Middle East and other sustained military campaigns, the war in Ukraine and associated economic sanctions on Russia, conditions in South America, Central America, China and Russia, and acts of terrorism or sabotage;

•evolving cybersecurity risks such as those involving unauthorized access, denial-of-service attacks, malicious software, data privacy breaches by employees, insiders or others with authorized access, cyber or phishing-attacks, ransomware, social engineering, physical breaches or other actions; and

•risks related to our ability to expand our business, including through the recruitment and retention of qualified personnel.

Reserve engineering is a process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reservoir engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, our reserve and PV-10 estimates may differ significantly from the quantities of oil, natural gas and NGLs that are ultimately recovered.

Should one or more of the risks or uncertainties materialize, or should underlying assumptions prove to be incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements.

All forward-looking statements, expressed or implied, included in this Quarterly Report are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this Quarterly Report.

MACH NATURAL RESOURCES LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.Organization and Nature of Business

Mach Natural Resources LP (the “Company”) is a Delaware limited partnership that was formed for the purpose of effectuating an initial public offering (the “Offering”) that closed in October 2023. The Company’s common units representing limited partnership interests (the “common units”) are listed on The New York Stock Exchange under the symbol “MNR.” The Company is an independent upstream oil and gas company focused on the acquisition, development and production of oil, natural gas and natural gas liquids (“NGL”) reserves in the Anadarko Basin region of Western Oklahoma, Southern Kansas and the panhandle of Texas.

The Company is a holding partnership whose sole material asset consists of membership interests in Mach Natural Resources Intermediate LLC (“Intermediate”). Intermediate wholly owns Mach Natural Resources Holdco LLC (“Holdco”), and Holdco wholly owns each of the Company’s three operating subsidiaries, BCE-Mach LLC (“BCE-Mach”), BCE-Mach II LLC (“BCE-Mach II”) and BCE-Mach III LLC (collectively, the “Mach Companies”).

The Company’s operations are governed by the provisions of its partnership agreement, executed by its general partner, Mach Natural Resources GP LLC (the “General Partner”) and the limited partners. The General Partner is managed and operated by the board of directors and executive officers of the General Partner. The members of the board of directors of the General Partner are appointed by the members of the General Partner, BCE-Mach Aggregator and Mach Resources in proportion to their respective limited partnership ownership in the Company.

Management has evaluated how the Company is organized and managed and identified a single reportable segment, which is the exploration and production of oil, natural gas and NGLs. Management considers the Company’s gathering, processing and marketing functions as ancillary to its oil and gas producing activities. All of the Company’s operations and assets are located in the United States, and its revenues are attributable to United States customers.

2.Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The unaudited consolidated financial statements included herein were prepared from records of the Company in accordance with generally accepted accounting principles in the United States (“US GAAP”) and include accounts of our wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated upon consolidation. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2024, as included in the Company’s Annual Report on Form 10-K. Results for interim periods are not necessarily indicative of results to be expected for the full year ending December 31, 2025. In the opinion of management, all adjustments, consisting primarily of normal recurring accruals that are considered necessary for a fair statement of the financial information, have been included.

Use of Estimates

The preparation of the financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, if any, at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although management believes these estimates are reasonable, actual results could differ from these estimates. The Company evaluates these estimates on an ongoing basis, using historical experience, consultation with experts and other methods the Company considers reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from the Company’s estimates. Any effects on the Company’s business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known.

Significant items subject to such estimates and assumptions include, but are not limited to, estimates of proved oil and natural gas reserves and related present value estimates of future net cash flows therefrom, the fair value determination of acquired assets and liabilities assumed in business combinations and the fair value estimates of commodity derivatives.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents for purposes of the financial statements. The Company maintains cash at financial institutions which may at

times exceed federally insured amounts. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk in this area.

Accounts Receivable

Accounts receivable primarily consists of receivables from joint interest owners on properties the Company operates and from sales of oil and natural gas production delivered to purchasers. The purchasers remit payment for production directly to the Company. Most payments for production are received within three months after the production date.

Accounts receivable are stated at amounts due from joint interest owners or purchasers, net of an allowance for credit losses. The Company extends credit to joint interest owners and generally does not require collateral, but typically has the ability to withhold future revenue disbursements to recover any non-payment of joint interest billings. Accounts receivable outstanding longer than the contractual payment terms are considered past due.

As of March 31, 2025, the Company had one customer that represented approximately 22.9% of our total joint interest receivables. As of December 31, 2024, the Company had one customer that represented approximately 22.6% of our total joint interest receivables.

The Company establishes its allowance for credit losses equal to the estimable portions of accounts receivable for which failure to collect is expected to occur primarily based on a historical loss rate analysis. The Company estimates uncollectible amounts based on a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history, the debtor’s expected ability to pay its obligation to the Company, the condition of the general economy and the industry as a whole. The Company considers forecasts of future economic conditions in its estimate of expected credit losses and adjusts its allowance for expected credit losses when necessary. The Company writes off specific accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for credit losses. At March 31, 2025 and December 31, 2024, the allowance for credit losses related to joint interest receivables were $3.7 million and $3.9 million, respectively, and the credit losses related to sales of oil and natural gas were not material.

Derivative Instruments

The Company is required to recognize its derivative instruments on the balance sheet as assets or liabilities at fair value with such amounts classified as current or long-term based on their anticipated settlement dates. The accounting for the changes in fair value of a derivative depends on the intended use of the derivative and resulting designation. The Company has not designated its derivative instruments as hedges for accounting purposes and, as a result, marks its derivative instruments to fair value and recognizes the cash and non-cash change in fair value on derivative instruments in the statement of operations. The cash and non-cash change in fair value on derivative instruments are included in the operating activities section in the statement of cash flows.

Oil and Natural Gas Operations

The Company uses the full cost method of accounting for its exploration and development activities. Under this method of accounting, costs of both successful and unsuccessful exploration and development activities are capitalized as proved oil and natural gas properties. This includes any internal costs that are directly related to exploration and development activities, but does not include any costs related to production, general corporate overhead or similar activities, which are expensed as incurred. Capitalized costs are depreciated using the unit-of production method. Under this method, depletion is computed at the end of each period by multiplying total production for the period by a depletion rate. The depletion rate is determined by dividing the total unamortized cost base plus future development costs by a net equivalent proved reserves at the beginning of the period. Depletion per barrel equivalent unit of production was $8.12 and $7.86 for the three months ended March 31, 2025 and 2024, respectively. Depreciation, depletion and amortization expense for oil and natural gas properties was $59.1 million and $63.7 million for the three months ended March 31, 2025 and 2024, respectively.

Under the full cost method, capitalized costs of oil and natural gas properties, net of accumulated depreciation, depletion and amortization, may not exceed the full cost “ceiling” at the end of each reporting period. The ceiling is calculated based on the present value of estimated future net cash flows from proved oil and gas reserves, discounted at 10%. The estimated future net revenues exclude future cash outflows associated with settling asset retirement obligations included in the net book value of oil and natural gas properties. Estimated future net cash flows are calculated using the preceding 12-months’ average price based on closing prices on the first day of each month. The net book value is compared to the ceiling

Table of Contents

MACH NATURAL RESOURCES LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

limitation on a quarterly basis. The excess, if any, of the net book value above the ceiling limitation is charged to expense in the period in which it occurs and is not subsequently reinstated. The ceiling limitation computation is determined without regard to income taxes due to the Internal Revenue Service (“IRS”) recognition of the Company as a flow-through entity. No impairments on proved oil and natural gas properties were recorded for the three months ended March 31, 2025 and 2024.

Costs associated with unevaluated properties are excluded from the full cost pool until the Company has made a determination as to the existence of proved reserves. The Company assesses all items classified as unevaluated property on a quarterly basis for possible impairment. The Company assesses properties on an individual basis or as a group if properties are individually insignificant. The assessment includes consideration of the following factors, among others: intent to drill; remaining lease term; geological and geophysical evaluations; drilling results and activity; the assignment of proved reserves; and the economic viability of development if proved reserves are assigned. As of March 31, 2025, and December 31, 2024, the Company had no properties excluded from the full cost pool. During any period in which these factors indicate an impairment, the cumulative drilling costs incurred to date for such property and all or a portion of the associated leasehold costs are transferred to the full cost pool and are then subject to amortization.

Sales of oil and natural gas properties being amortized are accounted for as adjustments to the full cost pool, with no gain or loss recognized, unless the adjustments would significantly alter the relationship between capitalized costs and proved oil, natural gas, and NGL reserves. A significant alteration would not ordinarily be expected to occur upon the sale of reserves involving less than 25% of the proved reserve quantities of a cost center.

Other Property and Equipment, Net

Other property and equipment primarily consists of gathering systems, processing plants, and salt water disposal systems. Property and equipment are capitalized and recorded at cost, while maintenance and repairs are expensed. Depreciation of such property and equipment is computed using the straight-line method over the estimated useful lives of the assets, which range from two to 39 years. Depreciation expense for other property and equipment was $2.4 million and $2.1 million for the three months ended March 31, 2025 and 2024, respectively.

Impairment losses are recorded on property and equipment used in operations and other long-lived assets held and used when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. Impairment is measured based on the excess of the carrying amount over the fair value of the asset. No impairment of other property and equipment was recorded for the three months ended March 31, 2025 or 2024.

Inventories

Inventories are stated at the lower of cost or net realizable value and consist of production and midstream equipment not placed in service as of March 31, 2025 and December 31, 2024, and crude oil held in storage. The Company’s production equipment primarily consists of oil and natural gas drilling or repair items such as tubing, casing and pumping units, as well as pipe for midstream operations, and are valued primarily using a weighted average cost method applied to specific classes of inventory items. Crude oil inventories are valued using the first-in, first-out inventory method. The components of inventory consisted of the following as of March 31, 2025 and December 31, 2024:

	March 31,<br>2025		December 31,<br>2024
Production equipment	$	24,231	$	23,475
Crude oil in storage	858		826
Total	$	25,089	$	24,301

Debt Issuance Costs

On February 27, 2025, the Company capitalized $14.6 million of new debt issuance costs related to the New Revolving Credit Facility (as defined in Note 6). The remaining unamortized debt issuance costs of $0.5 million from the Revolving Credit Agreement were retained and added to the additional amount of debt issuance costs associated with the New Revolving Credit Facility and are being amortized over the New Revolving Credit Facility’s term.

Table of Contents

MACH NATURAL RESOURCES LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Other assets include capitalized costs related to the New Revolving Credit Facility of $15.1 million, net of accumulated amortization of $0.3 million as of March 31, 2025. As of December 31, 2024, other assets include capitalized costs related to the Revolving Credit Agreement of $2.6 million, net of accumulated amortization of $2.0 million. These costs are being amortized over the terms of the related credit agreements and are reported as interest expense on the Company’s statement of operations.

Debt issuance costs and the discount associated with the Company’s Term Loan Credit Agreement are presented as a reduction of the carrying value of long-term debt on the Company’s balance sheet. As of December 31, 2024, the Company had unamortized debt issuance costs and discount of $11.8 million in relation to the Term Loan Credit Agreement. On February 27, 2025, the Company wrote-off the remaining unamortized balance of the debt issuance costs and discount associated with the Term Loan Credit Agreement. See Note 6 for further discussion.

Income Taxes

The Company is a limited partnership treated as a partnership for federal and state income tax purposes, with the exception of the state of Texas, with income tax liabilities and/or benefits of the Company passed through to partners. As such, with the exception of the state of Texas, we are not a taxable entity, we do not directly pay federal and state income tax and recognition has not been given to federal and state income taxes for our operations, except as described below.

Limited partnerships are subject to state income taxes in the state of Texas. Due to immateriality, income taxes related to the Texas franchise tax have been included in general and administrative expenses on the statement of operations and no deferred tax amounts were calculated.

The Company disallows the recognition of tax positions not deemed to meet a “more-likely-than not” threshold of being sustained by the applicable tax authority. The Company’s policy is to reflect interest and penalties related to uncertain tax positions in general and administrative expense, when and if they become applicable. The Company has not recognized any potential interest or penalties in its financial statements for the three months ended March 31, 2025. The Company’s tax years 2024, 2023, and 2022 remain open for examination by state authorities.

Asset Retirement Obligations

The Company records the fair value of the future legal liability for an asset retirement obligation (“ARO”) in the period in which the liability is incurred (at the time the wells are drilled or acquired), with the offsetting increase to property cost. These property costs are depreciated on a unit-of-production basis within the full cost pool. The liability accretes each period until it is settled or the well is sold, at which time the liability is satisfied.

The Company estimates a fair value of the obligation on each well in which it owns an interest by identifying costs associated with the future downhole plugging, dismantlement and removal of production equipment and facilities, and the restoration and reclamation of a field’s surface to a condition similar to that existing before oil and natural gas extraction or salt water disposal began.

In general, the amount of ARO and the costs capitalized will be equal to the estimated future cost to satisfy the abandonment obligation using current prices that are escalated by an assumed inflation factor up to the estimated settlement date, which is then discounted back to the date that the abandonment obligation was incurred using an estimated credit adjusted rate. If the estimated ARO changes materially, an adjustment is recorded to both the ARO and the long-lived asset. Revisions to estimated AROs can result from changes in retirement cost estimates, revisions to estimated inflation rates and

changes in the estimated timing of abandonment. The following is a reconciliation of ARO for the three months ended March 31, 2025 and 2024 (in thousands):

Revenue Recognition

Sales of oil, natural gas and NGL are recognized when production is sold to a purchaser at a fixed or determinable price, delivery has occurred, control has transferred and collectability of the revenue is probable. The Company’s performance obligations are satisfied at a point in time. This occurs when control is transferred to the purchaser upon delivery of contract specified production volumes at a specified point. The pricing provisions in the Company’s contracts are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, the quality of the oil or natural gas and the prevailing supply and demand conditions. As a result, the price of the oil, natural gas and NGL fluctuates to remain competitive with other available oil, natural gas and NGL supplies. The payment date is usually within 30 to 90 days of the end of the calendar month in which the commodity is delivered.

Our major market risk exposure is in the pricing applicable to our oil and natural gas production. Realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot market prices applicable to our natural gas production. Pricing for oil and natural gas production has been volatile and unpredictable for several years, and the Company expects this volatility to continue in the future. The prices the Company receives for production depend on many factors outside of our control. See Note 7 for a discussion of the Company’s management of price volatility.

Oil Sales

The Company’s oil sales contracts are structured where it delivers oil to the purchasers at the wellhead, where the purchaser takes custody, title and risk of loss of the product. Under this arrangement, the Company recognizes revenue when control transfers to the purchaser at the delivery point based on the price received from the purchaser. Oil revenues are recorded net of any third-party transportation fees and other applicable differentials in the Company’s statement of operations.

Natural Gas and NGL Sales

Under the Company’s natural gas and NGL sales contracts, it first delivers wet natural gas to a midstream processing entity. After processing, the residue gas is transported to the purchaser at the inlet to certain natural gas pipelines, where the purchaser takes control, title and risk of loss of the product. The NGL is delivered to the purchaser at the tailgate of the midstream processing plant, where the purchaser takes control, title and risk of loss of the product. For both natural gas sales and NGL sales, the Company evaluates whether it is the principal or the agent in the transaction. For those contracts where the Company has concluded it is the principal and the ultimate third party is its customer, the Company recognizes revenue on a gross basis, with gathering and processing fees presented as an expense in its statement of operations.

Midstream Revenue and Product Sales

The Company’s gathering and processing revenue is generated from owned gathering and compression systems and processing plants acquired in the Company’s acquisitions. The Company charges a gathering, compression and processing rate per MMBtu transported through the gathering system and processing plant. The Company also gathers and disposes of salt water from producing wells through an owned pipeline system and disposal wells. The Company charges a fixed rate

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

per barrel of water for disposal. Fees are recognized as revenue based on measured volume at the specified delivery points when the associated service is performed.

Product sales are generated from the Company’s sale of natural gas, oil and NGL production purchased from third parties and subsequently gathered and processed through the Company’s owned midstream facilities. Product sales include activity from certain third-party percent-of-proceeds contracts where the Company keeps a contractually based percentage of proceeds from the sale of natural gas and NGL production, as payment for processing natural gas from the third parties. The Company retains control of the purchased natural gas and NGLs prior to delivery to the purchaser and satisfies its

performance obligations by transferring control of the product at the delivery point and recognizes revenue based on the

contract price received from the purchaser. The costs of buying natural gas, oil and NGL production from third party shippers are included as costs of product sales on the statement of operations.

Transaction Price Allocated to Remaining Performance Obligations

For the Company’s product sales that are short-term in nature with a contract term of one year or less, the Company has utilized the practical expedient that exempts it from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. For the Company’s product sales that have a contract term greater than one year, the Company has utilized the practical expedient, which states that a company is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Each unit of product delivered to the customer represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Prior-Period Performance Obligations

The Company records revenue in the month production is delivered and control passes to the customer. However, settlement statements and payment may not be received for 30 to 90 days after the date production occurs, and as a result, the Company is required to estimate the amount of production that was delivered and the price that will be received for the sale of the product. The Company records variances between its estimates and actual amounts received in the month payment is received and such variances have historically not been significant.

Concentrations

The Company is subject to risk resulting from the concentration of its crude oil and natural gas sales and receivables with several significant purchasers. The following purchasers each accounted for more than 10% of the Company’s revenues for the periods indicated:

	Three Months Ended March 31,
	2025		2024
Philips 66 Company	29.3	%	27.8	%
NextEra Energy Marketing LLC	24.4	%	11.5	%
CVR Supply & Trading, LLC	10.7	%	*
Shell Oil Company	*		16.0	%

* Purchaser did not account for greater than 10% of oil, natural gas, and NGL sales for the period.

The Company’s receivables as of March 31, 2025 and 2024 from oil and gas sales are concentrated with the same counterparties noted above. The Company does not believe the loss of any single purchaser would materially impact its operating results, as crude oil and natural gas are fungible products with well-established markets and numerous purchasers.

Contract Balances

Cash received relating to future performance obligations is deferred and recognized when all revenue recognition criteria are met. Contract liabilities generated from such deferred revenue are not considered to be material as of March 31, 2025. The Company’s product sales and marketing contracts do not give rise to contract assets.

Recent Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, which requires disclosure of certain costs and expenses on an interim and annual basis in the notes to the financial statements. The guidance is effective for the first annual reporting period beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The amendments in this update are to be applied on a prospective basis, with the option for retrospective application. Early adoption is permitted. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures, but does not believe the adoption of the update will impact the Company’s financial position, results of operations or liquidity.

New Revolving Credit Facility

On February 27, 2025, the Company entered into a senior secured reserve-based revolving credit facility (the “New Revolving Credit Facility”), among the Company, the lenders and issuing banks party thereto from time to time and Truist Bank, as the administrative agent and collateral agent.

The New Revolving Credit Facility has (i) an initial borrowing base and elected commitment amount of $750.0 million, with a maximum commitment amount of $2.0 billion subject to borrowing base availability, (ii) a maturity date of February 27, 2029 and (iii) an interest rate equal to, at the Company’s election, (a) term SOFR (subject to a 0.10% per annum adjustment) plus a margin ranging from 3.00-4.00% per annum or (b) a base rate plus a margin ranging from 2.00-3.00% per annum, with the margin dependent upon borrowing base utilization at the time of determination. The Company is also required to pay a commitment fee of 0.50% per annum on the daily unused portion of the current aggregate commitments under the New Revolving Credit Facility.

The New Revolving Credit Facility’s borrowing base is redetermined semi-annually, in April and October. The New Revolving Credit Facility requires the Company to maintain as of the last day of each fiscal quarter (i) a consolidated total net leverage ratio of less than or equal to 3.00 to 1.00, and (ii) a current ratio of no less than 1.00 to 1.00.

The Company used borrowings from the New Revolving Credit Facility, together with cash on hand and proceeds from the February 2025 Offering (as defined below), to repay the Term Loan Credit Agreement and the Revolving Credit Agreement (as defined below) in full. As of March 31, 2025, there were $460.0 million of outstanding borrowings under the New Revolving Credit Facility with $5.0 million in outstanding letters of credit, and the remaining availability under the New Revolving Credit Facility was $285.0 million. The effective interest rate as of March 31, 2025 was 8.4%.

Term Loan Credit Agreement and Revolving Credit Agreement

On December 28, 2023, the Company entered into (i) a senior secured term loan credit agreement (the “Term Loan Credit Agreement”) with the lenders party thereto, Texas Capital Bank, as agent, and Chambers Energy Management, LP, as arranger, and (ii) a senior secured revolving credit agreement with a syndicate of lenders, including MidFirst Bank as the administrative agent.

Loans advanced to the Company under the Term Loan Credit Agreement were secured by a first-priority security interest on substantially all of our assets. The Term Loan Credit Agreement had (i) an aggregate principal amount of $825.0 million, (ii) a maturity date of December 31, 2026 and (iii) an interest rate equal to the three-month SOFR plus 6.50% plus a credit spread adjustment equal to 0.15%, provided that the three-month SOFR will not be less than 3.00%. The Term Loan Credit Agreement included customary covenants, mandatory repayments and events of default of financings of this type. As of December 31, 2024, there were $763.1 million of outstanding borrowings under the Term Loan Credit Agreement. The effective interest rate as of December 31, 2024 was 12.3%.

On February 27, 2025, the Company used borrowings from the New Revolving Credit Facility, together with cash on hand and proceeds from the February 2025 Offering, to repay the existing amounts outstanding under, and terminate, the Term Loan Credit Agreement. The termination of the Term Loan Credit Agreement was treated as a debt extinguishment. Accordingly, the Company recorded $18.5 million in debt extinguishment costs, which included $10.8 million related to the write-off of all unamortized discount and debt issuance costs and $7.7 million related to prepayment penalties.

Loans advanced to the Company under the Revolving Credit Agreement were secured by a super-priority security interest on substantially all of our assets. The Revolving Credit Agreement had (i) a maximum available principal amount of $75.0 million, with maximum commitments equal to $75.0 million, (ii) a maturity date of December 28, 2026 and (iii) an interest rate equal to the one, three, or six month SOFR, at the Company’s election, plus a credit spread adjustment equal to 0.10%, 0.15%, or 0.25%, respectively, in each case, plus 3.00%, provided that the applicable tenor SOFR will not be less than 3.50%. The Revolving Credit Agreement included customary covenants, mandatory repayments and events of default of financings of this type. The Company was also required to pay a commitment fee of 0.50% per annum on the average daily unused portion of the current aggregate commitments under the Revolving Credit Agreement. As of December 31, 2024, the Revolving Credit Agreement was undrawn, and there was $5.0 million in outstanding letters of credit.

On January 31, 2025, the Company borrowed $23.0 million under the Revolving Credit Agreement to fund the Flycatcher Acquisition.

On February 27, 2025, the Company used borrowings under the New Revolving Credit Facility to repay the existing amounts outstanding under and terminate the existing Revolving Credit Agreement. The termination of the Revolving Credit Agreement was treated as a debt modification based on the composition of the bank syndication in the New Revolving Credit Facility and the change in borrowing capacity.

The Company has not guaranteed the debt or obligations of any other party, nor does the Company have any other arrangements or relationships with other entities that could potentially result in consolidated debt or losses.

7. Derivative Contracts

The Company uses derivative contracts to reduce exposure to fluctuations in commodity prices. These transactions are in the form of fixed price swaps. While the use of these instruments limits the downside risk of adverse price changes, their use may also limit future revenues from favorable price changes. The Company does not intend to hold or issue derivative financial instruments for speculative trading purposes and has elected not to designate any of its derivative instruments for hedge accounting treatment.

Under fixed price swap contracts, the Company receives a fixed price for the contract and pays a floating market price to the counterparty over a specified period for a contracted volume. The fixed-price payment and the floating-price payment are netted, resulting in a net amount due to or from the counterparty. Crude oil derivative contracts are indexed and settled

based on NYMEX West Texas Intermediate (“WTI”) pricing and natural gas derivative contracts are indexed and settled

based on NYMEX Henry Hub pricing.

The Company reports the fair value of derivatives on the balance sheet in derivative contracts assets and derivative contracts liabilities as either current or noncurrent based on the timing of expected future cash flows of individual trades. See Note 8 for additional information regarding fair value measurements.

8. Fair Value Measurements

Fair value measurement is established by a hierarchy of inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions of what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of the inputs as follows:

Level 1 — Quoted prices are available in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 — Quoted prices for similar assets or liabilities in active markets or observable inputs for assets or liabilities in non-active markets.

Level 3 — Measurement based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from objective sources.

Assets and liabilities that are measured at fair value are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels.

Fair Value on a Recurring Basis

Derivative Contracts.    The Company determines the fair value of its derivative contracts using industry standard models that consider various assumptions including current market and contractual prices for the underlying instruments, time

value, and nonperformance risk. Substantially all of these inputs are observable in the marketplace throughout the full term of the contract and can be supported by observable data.

The following table provides fair value measurement information for financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2025 and December 31, 2024 (in thousands):

Liabilities:
Commodity derivative instruments	$	—	$	(11,106)	$	—	$	(11,106)

Fair Value on a Non-Recurring Basis

The Company determines the estimated fair value of its asset retirement obligations by calculating the present value of estimated cash flows related to plugging and abandonment liabilities using level 3 inputs. The significant inputs used to calculate such liabilities include estimates of costs to be incurred, the Company’s credit adjusted discount rates, inflation rates and estimated dates of abandonment. The asset retirement liability is accreted to its present value each period and the capitalized asset retirement cost is depleted with proved oil and natural gas properties using the unit of production method.

Business Combinations

Proved properties acquired as a result of business combinations were valued using an income approach based on underlying reserves projections as of the acquisition date. The income approach is considered a Level 3 fair value estimate and includes significant assumptions of future production, commodity prices, operating and capital cost estimates, the weighted average cost of capital for industry peers, which represents the discount factor, and risk adjustment factors based on reserve category. Price assumptions were based on observable market pricing, adjusted for historical differentials, while cost estimates were based on current observable costs inflated based on historical and expected future inflation.

Fair Value of Other Financial Instruments

The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, accounts payable, revenue payable, accrued interest payable, and other current liabilities approximate fair value due to the short-term maturities of these instruments.

The carrying amount of the Company’s credit agreements approximate fair value, as the current borrowing base rate does not materially differ from market rates of similar borrowings.

9. Equity Compensation and Deferred Compensation Plan

Equity-based compensation includes unit-based payment awards that are issued to employees and non-employees in exchange for services provided to the Company. Equity-classified unit-based payment awards are recognized at fair value on the grant date and amortized over the requisite service period. For awards with service-based vesting conditions only, the Company recognizes compensation cost using straight-line attribution. The Company uses accelerated attribution for awards that contain market or performance-based vesting conditions. The Company recognizes forfeitures as they occur.

Equity-based compensation is presented within general and administrative expense on our consolidated statements of operations.

On October 27, 2023, the Company adopted a new long-term incentive plan (the “Long-Term Incentive Plan”) for employees, consultants and directors in connection with the Offering. The Company issues phantom units (“Time-Based Phantom Units”) to certain employees of Mach Resources LLC (“Mach Resources”) and directors of the Company as compensation for services rendered to the Company. The Time-Based Phantom Unit awards for all employees of Mach Resources vest ratably on the first three anniversaries of the date of the grant, subject to the employee’s continued employment. Within 60 days of the vesting of a Time-Based Phantom Unit, the employee will receive a common unit of the Company. Each Time-Based Phantom Unit was granted with a corresponding distribution equivalent right (“DER”), which entitles the employee to receive a payment equal to the total distributions paid by the Company in respect of a common unit of the Company during the time the applicable phantom unit is outstanding. Payment of a DER occurs when its corresponding phantom unit vests, and in the event such phantom unit is forfeited, the corresponding DER is also forfeited.

Total non-cash compensation cost related to the Time-Based Phantom Units was $1.8 million and $1.2 million for the three months ended March 31, 2025 and 2024, respectively. As of March 31, 2025, there was $14.6 million of unrecognized compensation cost related to the Time-Based Phantom Units that is expected to be recognized over a weighted average period of approximately 2.1 years.

The aggregate fair value of share based awards that vested during the three-month period ended March 31, 2025 was approximately $31.8 thousand based on the unit price at the time of vesting.

The Company has awarded performance based phantom units (“Performance Phantom Units”) to certain of its executive officers under the Long-Term Incentive Plan. The number of common units issued pursuant to each Performance Phantom Unit award agreement will be from 0% to 200% of the target number of Performance Phantom Units thereunder based on a combination of the Company’s (i) total shareholder return (“TSR”), (ii) relative TSR compared to the TSR of the companies in the Company’s designated peer group and (iii) total recordable incident rate, in each case, for the applicable performance period. The Performance Phantom Unit awards are broken into two categories: long-term performance units, which have a three-year performance period, and short-term performance units, which are broken into three separate one-year tranches with performance periods in each one-year period. Performance Phantom Units vest based on the achievement of the applicable performance metrics at the end of the applicable performance period, subject generally to the applicable executive officer’s continued employment through such performance period. Within 60 days of the vesting of a Performance Phantom Unit, the executive officer will receive a common unit of the Company. Each Performance Phantom

Unit was granted with a corresponding DER. Payment of any such DER occurs when its corresponding Performance Phantom Unit vests, and in the event such Performance Phantom Unit is forfeited, the corresponding DER is also forfeited. The grant date fair values of the Performance Phantom Units with market conditions were determined using the Monte Carlo simulation method and are being recorded ratably from the grant date to the end of the applicable performance period.

The table below summarizes the assumptions used in the Monte Carlo simulation to determine the grant date fair value of Performance Phantom Units granted during the year ended December 31, 2024, and the period ended March 31, 2025.

Grant date	May 3, 2024	January 1, 2025
Period for volatility, correlations, and risk-free rate	2.66 years	3.00 years
Risk-free interest rate	4.61%	4.23%
Implied equity volatility	57.25%	50.57%
Unit price on date of grant	$20.44	$17.18

Total non-cash compensation cost related to the Performance Phantom Units was $0.3 million for the three months ended March 31, 2025. As of March 31, 2025, there was $1.9 million of unrecognized compensation cost related to phantom units that is expected to be recognized over a weighted average period of approximately 2.1 years.

10. Commitments and Contingencies

Legal Matters.    In the ordinary course of business, the Company may at times be subject to claims and legal actions including, but not limited to, title disputes, royalty disputes, contract claims, personal injury claims and employment claims. The Company accrues liabilities when it is probable that future costs will be incurred and such costs can be reasonably estimated. Such accruals are based on developments to date and the Company’s estimates of the outcomes of these matters. Nevertheless, actual outcomes may differ significantly from the Company’s assessment. As of March 31, 2025 and December 31, 2024 the Company has accrued approximately $1.5 million in accrued liabilities pertaining to these matters. Management does not expect that the impact of such matters will have a materially adverse effect on the Company’s financial position, results of operations or cash flows.

Environmental Matters.    The Company is subject to various federal, state and local laws and regulations relating to pollution and the protection of the environment. These laws, which are often changing, regulate the discharge and disposal of materials into the environment and may require the Company to obtain permits for, remove or mitigate the environmental effects of the disposal or release of petroleum or chemical substances at various sites.

The Company accounts for environmental contingencies in accordance with the accounting guidance related to accounting for contingencies. Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations, which do not contribute to current or future revenue generation, are expensed. Liabilities are recorded when environmental assessments and/or clean-ups are probable and the costs can be reasonably estimated.

NGL Sales and Gas Transportation Commitments.    The Company is party to a NGL sales contract, which includes certain NGL volume commitments in the event the Company elects not to reduce its committed quantity, at its option. To the extent the Company does not deliver NGL volumes in sufficient quantities to meet the commitment and does not elect to reduce its committed quantity, it would be required to pay a deficiency fee. The Company is currently delivering at least the minimum volumes. Additionally, the Company has natural gas firm transportation agreements terminating in 2025. For the three months ended March 31, 2025 and 2024, the Company incurred approximately $0.1 million and $1.2 million, respectively, of transportation charges under these agreements. Total remaining payments under these contracts were approximately $0.1 million as of March 31, 2025.

Contributions to 401(k) Plan.    The Company sponsors a 401(k) plan under which eligible employees may contribute a portion of their total compensation up to the maximum pre-tax threshold through salary deferrals. The plan provides a company match on 100% of salary deferrals that do not exceed 10% of compensation. We contributed $1.1 million and $1.0 million for the three months ended March 31, 2025 and 2024, respectively.

11. Leases

Nature of Leases

The Company has operating leases on office spaces, various vehicles and compressors with remaining lease durations in excess of one year. These leases have various expiration dates through 2029. The vehicles are used for field operations and leased from third parties. The Company recognizes right-of-use asset and lease liability on the balance sheet for all leases with lease terms of greater than one year. Short-term leases that have an initial term of one year or less are not capitalized.

Discount Rate

As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company’s incremental borrowing rate reflects the estimated rate of interest that it would pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term and in a similar economic environment.

Future amounts due under operating lease liabilities as of March 31, 2025, were as follows (in thousands):

Remaining 2025	$	4,554
2026	4,365
2027	3,287
2028	2,120
2029	1,254
Total lease payments	$	15,580
Less: imputed interest	(1,793)
Total	$	13,787

12. Partners’ Capital

On February 7, 2025, the Company completed a public offering of 12,903,226 common units at a price to the public of $15.50 per common unit, less underwriting discounts and commissions (the “February 2025 Offering”). On February 12, 2025, the underwriters of the public offering fully exercised their option to purchase an additional 1,935,483 common units at a price to the public of $15.50 per common unit, less underwriting discounts and commissions. The sale of the Company’s common units resulted in gross proceeds of $230.0 million and net proceeds of $221.1 million, after deducting underwriting fees and offering expenses. Proceeds from the offering were used to repay a portion of the Term Loan Credit Agreement and Revolving Credit Agreement.

On September 9, 2024, the Company completed a public offering of 7,272,728 common units at a price to the public of $16.50 per common unit, less underwriting discounts and commissions. On September 24, 2024, the underwriters of the

public offering partially exercised their option to purchase an additional 1,018,465 common units at a price to the public of $16.50 per common unit, less underwriting discounts and commissions. The sale of the Company’s common units resulted in gross proceeds of $136.8 million and net proceeds of $128.9 million, after deducting underwriting fees and offering expenses. Proceeds from the offering were used to fund the Western Kansas Acquisition and the Ardmore Basin Acquisition.

As of March 31, 2025 and December 31, 2024, the Company had 118,334,519 and 103,490,483 common units outstanding, respectively.

The Company distributed $0.50 per unit for total cash distributions of $59.2 million for the three months ended March 31, 2025.

13. Earnings Per Common Unit

The Company has a single class of common units. The Company has potentially dilutive securities as of March 31, 2025, which consist of phantom units issued under the Company’s long-term incentive plan. The treasury stock method is used to determine the dilutive impact for the Company’s phantom units. There were 0.1 million phantom units that were considered dilutive for the three months ended March 31, 2025. As of March 31, 2025 there were 15.4 thousand phantom units that were considered antidilutive and thus excluded from the calculation of diluted earnings per common unit. As of March 31, 2024, there were no units that were considered antidilutive.

The following represents the computation of basic and diluted earnings per common unit for the three months ended March 31, 2025 and 2024 (in thousands, except per unit data):

	Three Months Ended March 31,

14. Related Party Transactions

Management Services Agreement

On October 27, 2023, the Company entered into a management services agreement (the “MSA”) with Mach Resources. Under the MSA, Mach Resources manages and performs all aspects of oil and gas operations and other general and administrative functions for the Company and the Company (i) will pay Mach Resources an annual management fee of approximately $7.4 million and (ii) reimburse Mach Resources for the costs and expenses of the services provided. On a monthly basis, the Company distributes funding to Mach Resources for performance under the MSA. During the three months ended March 31, 2025 and 2024, the Company paid Mach Resources $31.3 million (inclusive of $1.9 million in management fees presented as general and administrative expense - related party in the statement of operations) and $30.4 million (inclusive of $1.9 million as management fees presented in general and administrative expense - related party in the statement of operations), respectively. As of March 31, 2025 and December 31, 2024, the Company owed $1.8 million and $2.0 million, respectively, to Mach Resources, presented as accounts payable - related party.

Common units purchased by BCE-Mach Aggregator

In connection with the February 2025 Offering, BCE-Mach Aggregator, an affiliate of our General Partner, purchased 5,161,290 common units at the public offering price, which accounted for $79.2 million of the proceeds received by the Company in the February 2025 Offering, after deducting underwriting fees. In connection therewith, the underwriters received a reduced underwriting discount on such common units purchased by BCE-Mach Aggregator compared to other common units sold to the public in the February 2025 Offering.

15. Segment Information

Management has evaluated that the Company is organized and managed as a single reportable segment, which is the exploration and production of oil, natural gas and NGLs (“E&P Segment”). All of the Company’s operations and assets are located in the United States, and its revenues are attributable to United States customers.

The accounting policies of the E&P Segment are the same as those described in Note 2.

The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer and Director. The CODM uses consolidated net income as presented on the accompanying statements of operations to measure E&P Segment profit or loss, and to evaluate income generated from E&P Segment assets in deciding whether to reinvest profits into operational activities or to use profits for other purposes, such as debt reduction, acquisitions, or distributions to unitholders. Additionally, consolidated net income is used in assessing budget versus actual results and in benchmarking to the Company’s competitors.

The following table summarizes total revenues, significant expenses, net income and capital expenditures related to the E&P Segment for the three months ended March 31, 2025 and 2024 (in thousands):

16. Subsequent Events

XTO Acquisition

On March 25, 2025, the Company entered into an Equity Interest Purchase Agreement with XTO Energy, pursuant to which the Company would acquire certain oil and gas assets located in Oklahoma, Kansas and Wyoming, for consideration of $60.0 million in cash, subject to certain customary purchase price adjustments (the “XTO Acquisition”). The transaction closed on April 30, 2025. As of March 31, 2025, the Company had paid a deposit of $6.0 million which is included in other assets on the Company’s balance sheet. The Company used borrowings on the New Revolving Credit Facility and cash on hand to fund the XTO Acquisition.

New Credit Facility

Subsequent to March 31, 2025, the Company has borrowed $65.0 million on the New Revolving Credit Facility. Borrowings were used to fund the XTO Acquisition and for general corporate purposes.

Distribution Declaration

On May 8, 2025, the Company declared its quarterly distribution for the first quarter of 2025 of $0.79 per common unit, which will be paid on June 5, 2025.

The Company has evaluated subsequent events through the date of issuance of these financial statements to ensure that any subsequent events that met the criteria for recognition and disclosure in this Quarterly Report have been properly included.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to provide the reader of the financial statements with a narrative from the perspective of management on the financial condition, results of operations, liquidity and certain other factors that may affect the Company’s operating results. The following discussion and analysis should be read in conjunction with our unaudited consolidated financial statements and related notes included in Part I, Item I of this Quarterly Report and also with “Risk Factors” included in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024. The following information updates the discussion of our financial condition provided in our previous filings, and analyzes the changes in the results of operations for the three months ended March 31, 2025 and 2024.

The following discussion contains forward-looking statements that reflect our future plans, estimates, beliefs and expected performance, which may affect our future operating results and financial position. The forward-looking statements are dependent upon events, risks and uncertainties that may be outside our control. Actual results and the timing of the events could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, market prices for oil, natural gas and NGLs, production volumes, estimates of proved reserves, capital expenditures, economic, inflationary and competitive conditions, drilling results, regulatory changes and other uncertainties, as well as those factors discussed below and elsewhere in this Quarterly Report, particularly under “Cautionary Statement Regarding Forward-Looking Statements,” all of which are difficult to predict. In light of these risks, uncertainties and assumptions, the forward-looking events discussed may not occur. We do not undertake any obligation to publicly update any forward-looking statements except as otherwise required by applicable law.

Overview

We are an independent upstream oil and gas company focused on the acquisition, development and production of oil, natural gas and NGL reserves in the Anadarko Basin region of Western Oklahoma, Southern Kansas and the panhandle of Texas.

Within our operating areas, our assets are prospective for multiple formations, most notably the Oswego, Woodford and Mississippian formations. Our experience in the Anadarko Basin and these formations allows us to generate significant cash available for distribution from these low declining assets in a variety of commodity price environments. We also own an extensive portfolio of complementary midstream assets that are integrated with our upstream operations. These assets include gathering systems, processing plants and water infrastructure. Our midstream assets enhance the value of our properties by allowing us to optimize pricing, increase flow assurance and eliminate third-party costs and inefficiencies. In addition, our owned midstream systems generate third-party revenue.

Market Outlook

Our financial results depend on many factors, particularly commodity prices and our ability to find, develop and market our production on economically attractive terms. Commodity prices are affected by many factors outside of our control, including changes in market supply and demand. The oil and natural gas industry is cyclical and commodity prices are highly volatile and we expect continued and increased pricing volatility in the crude oil and natural gas markets. Regional and worldwide economic activity, including any economic downturn or recession that has occurred or may occur in the future, extreme weather conditions and other substantially variable factors, influence market conditions for these products. Between January 1, 2024 and March 31, 2025, NYMEX WTI prices for crude oil ranged from $65.75 to $86.91 per Bbl, and the NYMEX Henry Hub price of natural gas ranged from $1.58 to $4.49 per MMBtu. The war in Ukraine and conflict in the Middle East, uncertainty regarding interest rates, global supply chain disruptions, the potential for significant new tariffs, concerns about a potential economic downturn or recession, and instability in the financial sector have contributed to recent economic and pricing volatility and may continue to impact pricing throughout 2025.

Between 2022 and 2024, the Federal Reserve raised the target range for the federal funds rate in an effort to curb inflation. In September 2024 and November 2024, the Federal Reserve lowered the target range for the federal funds rate to its current range of 4.25% to 4.50% in light of the reduced inflation. In March 2025, inflation, as measured by the consumer price index, was 2.4%. We cannot predict the future inflation rate but to the extent we experience high inflation, we may see cost increases in our operations, including costs for drill rigs, workover rigs, tubulars and other well equipment, as well as increased labor costs. We continue to evaluate actions to mitigate supply chain and inflationary pressures and work closely with other suppliers and contractors to ensure availability of supplies on site, especially fuel, steel and chemical supplies which are critical to many of our operations. However, these mitigation efforts may not succeed or may be insufficient. Further, if we are unable to recover higher costs through higher commodity prices, our current revenue stream,

estimates of future reserves, borrowing base calculations, impairment assessments of oil and natural gas properties, and values of properties in purchase and sale transactions would all be significantly impacted.

How We Evaluate Our Operations

We use a variety of financial and operational metrics to assess the performance of our operations, including the following sources of our revenue, principal components of our cost structure and other financial metrics:

•net production volumes;

•realized prices on the sale of oil, natural gas and NGLs;

•lease operating expense;

•Adjusted EBITDA; and

•cash available for distribution.

Factors Affecting the Comparability of Our Future Results of Operations to Our Historical Results of Operations

Our future results of operations may not be comparable to our historical results of operations for the periods presented, primarily for the reasons described below.

Acquisitions

We have completed three acquisitions since the beginning of 2024. These acquisitions are reflected in our results of operations as of and after the date of completion for each such acquisition. As a result, periods prior to each such acquisition will not contain the results of such acquired assets which will affect the comparability of our results of operations for certain historical periods. We may continue to grow our operations through acquisitions when economical, including by funding such acquisitions under our New Revolving Credit Facility.

Revenue and Other Operating Income

Oil, natural gas and NGL sales

Revenues from oil, natural gas and NGL sales decreased $2.5 million, or 1%, for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. This decrease was primarily related to a 10% production decrease, which resulted in decreased oil, natural gas and NGL sales of $23.6 million. These decreases were offset with an overall increase in the average selling price of our products, which resulted in an increase in oil, natural gas, and NGL sales of $21.0 million.

Production

Production decreased 815 MBoe, or 10% for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. The decrease was primarily a result of natural well declines on our producing wells, partially offset with new production on wells completed subsequent to March 31, 2024.

Oil and Natural Gas Derivatives

For the three-month period ended March 31, 2025, we had realized gains on derivative instruments of $1.6 million and unrealized losses of $42.3 million for total losses of $40.7 million. For the three-month period ended March 31, 2024, we

Table of Contents

had realized gains on derivative instruments of $4.0 million and unrealized losses of $33.2 million for total losses of $29.3 million. The increase in unrealized losses is primarily due to the increase in natural gas prices. The decrease in realized gains is primarily due to a decrease in the spread between settlement prices and contract prices.

Product Sales

Product sales increased $1.6 million, or 24% for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. This increase was primarily a result of increases in third-party volumes resulting in higher overall product sales and an increase in the average selling price on natural gas and NGLs. These increases corresponded with the increase in our cost of product sales noted below.

Midstream Revenue

Midstream revenue decreased $0.1 million, or 1% for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024, primarily due to lower salt water disposal revenue for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024.

Operating expenses

The following table summarizes our expenses for the periods indicated and includes a presentation of certain expenses on a per Boe basis, as we use this information to evaluate our performance relative to our peers and to identify and measure trends we believe may require additional analysis:

All values are in US Dollars.

Gathering and processing expense

Gathering and processing expense decreased $3.8 million, or 12%, and $0.07 per Boe, or 2%, for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024, primarily as a result of the 13% decline in natural gas production and the 9% decline in NGL production.

Lease operating expense

Lease operating expense increased $8.0 million, or 20% for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024, primarily due to a $3.0 million increase in salt water disposal related

Table of Contents

expenses, and a $2.4 million increase related to field and contract labor. Lease operating expenses per Boe increased by $1.66 primarily from the increases noted above, combined with a decrease in overall production from period to period.

Production taxes

Production taxes increased $22.0 thousand for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. This increase was in line with the increase in oil, natural gas and NGL sales.

Midstream operating expense

Midstream operating expense increased $0.4 million, or 16% for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024, primarily due to increased plant operating expenses of $0.3 million.

Cost of product sales

Cost of product sales increased $1.9 million, or 31% for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. This increase was primarily a result of increases in third-party volumes resulting in higher overall cost of product sales and the increase in the average selling price on natural gas and NGLs. These increases were consistent with the decrease in product sales noted above.

Depreciation, depletion, amortization and accretion expense

Depreciation, depletion, amortization and accretion expense for oil and natural gas properties decreased by $4.2 million, or 6% for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. The decrease is primarily the result of a decrease in production used to calculate depletion.

General and administrative costs

General and administrative costs increased $0.5 million, or 5% for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. The increase in general and administrative costs was primarily a result of an increase in equity compensation of $0.9 million for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024.

Liquidity and Capital Resources

Our primary sources of liquidity and capital are cash flows generated by operating activities, borrowings under the New Revolving Credit Facility, and proceeds from the issuance of equity and debt. At March 31, 2025, outstanding borrowings under the New Revolving Credit Facility were $460.0 million with $5.0 million in letters of credit outstanding, and the remaining availability under the New Revolving Credit Facility was $285.0 million at March 31, 2025.

We may need to utilize the public equity or debt markets and bank financings to fund future acquisitions or capital expenditures, but the price at which our common units will trade could be diminished as a result of the limited voting rights of unitholders. We expect to be able to issue additional equity and debt securities from time to time as market conditions allow to facilitate future acquisitions. Our ability to finance our operations, including funding capital expenditures and acquisitions, to meet our indebtedness obligations or to refinance our indebtedness will depend on our ability to generate cash in the future. Our ability to generate cash is subject to a number of factors, some of which are beyond our control, including commodity prices, particularly for oil and natural gas, and our ongoing efforts to manage operating costs and maintenance capital expenditures, as well as general economic, financial, competitive, legislative, regulatory, weather and other factors.

Our partnership agreement requires us to distribute all of our cash on hand at the end of each quarter, less reserves established by our general partner, which we refer to as “available cash.” Our quarterly cash distributions may vary from quarter to quarter as a direct result of variations in the performance of our business, including those caused by fluctuations in commodity prices. Any such variations may be significant, and as a result, we may pay limited or even no cash distributions to our unitholders.

Historically, our business plan has focused on acquiring and then exploiting the development and production of our assets. We spent approximately $52.0 million during the three-month period ended March 31, 2025 on development costs and our budget for 2025 is between $260.0 million and $280.0 million. For purposes of calculating our cash available for distribution, we define development costs as all of our capital expenditures, other than acquisitions. Our development

Table of Contents

efforts and capital for 2025 is anticipated to focus on a mix of drilling Oswego, Woodford, Red Fork and Mississippian wells.

During the three-month period ended March 31, 2025, we spent approximately $42.8 million on drilling and completion activities and related equipment and spud 6.7 net wells while bringing online 9.3 net wells, $8.2 million on remedial workovers and other capital projects, $1.0 million on midstream and other property and equipment capital projects and $26.3 million on acquisitions.

Our 2025 capital expenditures program is largely discretionary and within our control. We could choose to defer a portion of these planned 2025 capital expenditures depending on a variety of factors, including, but not limited to, the success of our drilling activities, prevailing and anticipated prices for oil and natural gas, the availability of necessary equipment, including acid to be used for our acid stimulation completion, infrastructure and capital, the receipt and timing of required regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other working interest owners. A deferral of planned capital expenditures, particularly with respect to drilling and completing new wells, could result in a reduction in anticipated production and cash flows and reduce our cash available for distribution to unitholders.

Cash Flows

The following table summarizes our cash flows for the periods indicated:

	Three Months Ended March 31,
(in thousands)	2025		2024
Net cash provided by operating activities	$	142,519	$	143,953
Net cash used in investing activities	$	(78,010)	$	(54,720)
Net cash used in financing activities	$	(162,495)	$	(90,725)

Net cash provided by operating activities

Net cash provided by operating activities decreased $1.4 million for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. The decrease in net cash provided by operating activities is primarily a result of a decrease in production, offset with an increase in the average selling price of natural gas.

Net cash used in investing activities

Net cash used in investing activities increased $23.3 million for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. The increase in net cash used in investing activities is primarily a result of an increase in cash used in acquisitions of $28.2 million. This was offset by a decrease in capital expenditures on our other property and equipment of $3.2 million.

Net cash used in financing activities

Net cash used in financing activities increased $71.8 million for the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024. The increase in net cash used in investing activities is primarily due to increases in cash used for repayments of our term loan of $763.1 million, prepayment penalties of $7.7 million and new debt issuance costs of $13.4 million. These were partially offset by an increase in cash provided by borrowings on our credit facilities, net of repayments of $460.0 million, and an increase in cash provided from proceeds from follow-on offerings of $221.6 million. Additionally, there was a decrease in cash used for distributions of $31.1 million in the three-month period ended March 31, 2025, as compared to the three-month period ended March 31, 2024.

Debt Agreements

New Revolving Credit Facility

On February 27, 2025, the Company entered into the New Revolving Credit Facility, among the Company, the lenders and issuing banks party thereto from time to time and Truist Bank, as the administrative agent and collateral agent.

The New Revolving Credit Facility has (i) an initial borrowing base and elected commitment amount of $750.0 million, with a maximum commitment amount of $2.0 billion subject to borrowing base availability, (ii) a maturity date of February 27, 2029 and (iii) an interest rate equal to, at the Company’s election, (a) term SOFR (subject to a 0.10% per

Table of Contents

annum adjustment) plus a margin ranging from 3.00-4.00% per annum or (b) a base rate plus a margin ranging from 2.00-3.00% per annum, with the margin dependent upon borrowing base utilization at the time of determination. The Company is also required to pay a commitment fee of 0.50% per annum on the daily unused portion of the current aggregate commitments under the New Revolving Credit Facility. The Company used borrowings from the New Revolving Credit Facility, together with cash on hand and proceeds from the February 2025 Offering, to repay the Term Loan Credit Agreement and the Revolving Credit Agreement in full.

We have not guaranteed the debt or obligations of any other party, nor do we have any other arrangements or relationships with other entities that could potentially result in consolidated debt or losses.

Contractual Obligations and Commitments

We are a party to firm transportation contracts for the transport of natural gas. We paid approximately $0.1 million in firm transportation contracts for the three-month period ended March 31, 2025 and expect to pay approximately $0.1 million in firm transportation contracts through 2025. For further information on firm transportation contracts, see Note 10 of our consolidated financial statements.

Operating lease obligations

Our operating lease obligations include long-term lease payments for office space, vehicles, equipment related to exploration, development and production activities. We paid approximately $2.1 million in operating lease payments for the three-month period ended March 31, 2025 and expect to pay approximately $15.6 million in operating lease payments through 2029. For further information on our operating lease obligations, see Note 11 of our consolidated financial statements.

Non-GAAP Financial Measures

Adjusted EBITDA

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 loss (gain) on derivative instruments, (4) loss on debt extinguishment, (5) equity-based compensation expense and (6) (gain) loss 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 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 adjusted for (1) interest expense, net, (2) depreciation, depletion, amortization and accretion, (3) unrealized loss (gain) on derivative instruments, (4) loss on debt extinguishment, (5) equity-based compensation expense, (6) (gain) loss on sale of assets, net, (7) cash interest expense, net, (8) development costs and (9) change in accrued realized derivative settlements. Development costs

Table of Contents

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.

Reconciliation of Adjusted EBITDA and Cash Available for Distribution to GAAP Financial Measures

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are disclosed in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” in our Annual Report for the year ended December 31, 2024. No modifications have been made during the three months ended March 31, 2025.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk, including the effects of adverse changes in commodity prices and interest rates as described below. The primary objective of the following information is to provide quantitative and qualitative information about our potential exposure to market risks. The term “market risk” refers to the risk of loss arising from adverse changes in commodity prices and interest rates. The disclosures are not meant to be precise indicators of expected future losses but rather indicators of reasonably possible losses.

Table of Contents

Commodity Price Risk

Oil and gas revenue

Our revenue and cash flow from operations are subject to many variables, the most significant of which is the volatility of commodity prices. Commodity prices are affected by many factors outside of our control, including changes in market supply and demand, which are impacted by global economic factors, pipeline capacity constraints, inventory levels, basis differentials, weather conditions and other factors. Commodity prices have long been volatile and unpredictable, and we expect this volatility to continue in the future.

There can be no assurance that commodity prices will not be subject to continued wide fluctuations in the future. A substantial or extended decline in such prices could have a material adverse effect on our financial position, results of operations, cash flows and quantities of oil and gas reserves that may be economically produced, which could result in impairments of our oil and natural gas properties.

Commodity derivative activities

To reduce the impact of fluctuations of commodity prices on our total revenue and other operating income, we have historically used, and we expect to continue to use, commodity derivative instruments, primarily swaps, to hedge price risk associated with a portion of our anticipated production. Our hedging instruments allow us to reduce, but not eliminate the potential effects of the variability in cash flow from operations due to fluctuations in commodity prices and provide increased certainty of cash flows for funding our drilling program and debt service requirements. These instruments provide only partial price protection against declines in prices and may partially limit our potential gains from future increases in prices. We do not enter derivative contracts for speculative trading purposes. The New Revolving Credit Facility contains various covenants and restrictive provisions which, among other things, limit our ability to enter into commodity price hedges exceeding a certain percentage of production.

Our hedging activities are intended to support oil and natural gas prices at targeted levels and manage our exposure to natural gas price volatility. Under swap contracts, the counterparty is required to make a payment to us for the difference between the swap price specified in the contract and the settlement price, which is based on market prices on the settlement date, if the settlement price is below the swap price. We are required to make a payment to the counterparty for the difference between the swap price and the settlement price if the swap price is below the settlement price. See Note 7 of our consolidated financial statements for further information on our open derivative positions and valuation as of March 31, 2025.

Counterparty and Customer Credit Risk

By using derivative instruments to hedge exposures to changes in commodity prices, we expose ourselves to the credit risk of our counterparties. Credit risk is the potential failure of the counterparty to perform under the terms of a contract. When the fair value of a derivative contract is positive, the counterparty is expected to owe us, which creates credit risk. To minimize the credit risk in derivative instruments, it is our policy to enter into derivative contracts only with counterparties that are creditworthy financial institutions deemed by management as competent and competitive market makers. The creditworthiness of our counterparties is subject to periodic review. As of March 31, 2025, we had derivative instruments in place with four different counterparties. We believe our counterparties currently represent acceptable credit risks. We are not required to provide credit support or collateral to our counterparties under current contracts, nor are they required to provide credit support or collateral to us.

Substantially all of our revenue and receivables result from oil and gas sales to third parties operating in the oil and gas industry. Our receivables also include amounts owed by joint interest owners in the properties we operate. Both our purchasers and joint interest partners have recently experienced the impact of significant commodity price volatility as discussed above under “— Commodity Price Risk — Oil and Gas Revenue.” This concentration of customers and joint interest owners may impact our overall credit risk in that these entities may be similarly affected by changes in commodity prices and economic and other conditions. In the case of joint interest owners, we often have the ability to withhold future revenue disbursements to recover non-payment of joint interest billings.

Interest Rate Risk

Variable rate debt

At March 31, 2025, we had $460.0 million of debt outstanding under the New Revolving Credit Facility. Borrowings outstanding under the New Revolving Credit Facility bore an interest rate of 7.9% as of March 31, 2025. Assuming no

Table of Contents

change in the amount outstanding, the impact on interest expense of a 1% (or 100 basis points) increase or decrease in the assumed weighted average interest rate on our variable interest debt would be approximately $4.6 million per year based on our borrowings outstanding at March 31, 2025.

Interest rate derivative activities

As of March 31, 2025, we did not have any derivative arrangements to protect against fluctuations in interest rates applicable to our outstanding indebtedness, but we may enter into such derivative arrangements in the future. To the extent we enter into any such interest rate derivative arrangement, we would be subject to risk for financial loss.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company’s Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2025. Based on such evaluation, such officers have concluded that, as of March 31, 2025, the Company’s disclosure controls and procedures are designed and effective to ensure that information required to be included in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms and that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is accumulated and communicated to the Company’s management including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

In designing and evaluating the Company’s disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the control system will be met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events and the application of judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of these and other inherent limitations of control systems, there is only reasonable assurance that the Company’s controls will succeed in achieving their goals under all potential future conditions.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the three-month period ended March 31, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

The Company may, from time to time, be involved in litigation and claims arising out of its operations in the normal course of business including, but not limited to, title disputes, royalty disputes, contract claims, personal injury claims and employment claims. See Note 10 of the notes to our consolidated financial statements included in Item 1 of Part I of this report for information regarding our estimation and provision for potential losses related to litigation and regulatory proceedings.

The Company, as an owner and operator of oil and gas properties, is subject to various federal, state and local laws and regulations relating to disposal or discharge of materials into, and pollution or protection of, the environment. These laws and regulations may, among other things, impose liability on the lessee under an oil and gas lease for the cost of pollution cleanup resulting from operations and subject the lessee to liability for pollution damages. In some instances, the Company may be directed to suspend or cease operations in the affected area. The Company maintains insurance coverage that is customary in the industry, although the Company is not fully insured against all environmental risks.

The Company is not aware of any environmental claims existing as of March 31, 2025. There can be no assurance, however, that current regulatory requirements will not change or will not be interpreted or enforced differently, or past non-compliance with environmental laws and regulations or other issues will not be discovered on the Company’s oil and gas properties.
