Organization

ARLP is a Delaware limited partnership listed on the NASDAQ Global Select Market under the ticker symbol “ARLP.” ARLP was formed in May 1999 and completed its initial public offering on August 19, 1999 when it acquired substantially all of the coal production and marketing assets of Alliance Resource Holdings, Inc., a Delaware corporation, and its subsidiaries. We are managed by our general partner, MGP, a Delaware limited liability company which holds a non-economic general partner interest in ARLP.

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts and operations of the ARLP Partnership and present our financial position as of June 30, 2025 and December 31, 2024, the results of our operations and comprehensive income for the three and six months ended June 30, 2025 and 2024 and cash flows for the six months ended June 30, 2025 and 2024. All intercompany transactions and accounts have been eliminated.

These condensed consolidated financial statements and notes are prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim reporting and do not include all the information normally included with financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) of the United States. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024.

These condensed consolidated financial statements and notes are unaudited. However, in the opinion of management, these condensed consolidated financial statements reflect all normal recurring adjustments necessary for a fair presentation of the results for the periods presented. Results for interim periods are not necessarily indicative of results to be expected for the full year ending December 31, 2025.

Use of Estimates

The preparation of the ARLP Partnership’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in our condensed consolidated financial statements. Actual results could differ from those estimates.

Table of Contents

Investments

Our investments and ownership interests in equity securities without readily determinable fair values in entities in which we do not have a controlling financial interest or significant influence are accounted for using a measurement alternative other than fair value. The measurement alternative is historical cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same entity. Distributions received on those investments are recorded as income unless those distributions are considered a return on investment, in which case the historical cost is reduced. We account for our ownership interests in Infinitum Electric, Inc. (“Infinitum”) and Ascend Elements, Inc. (“Ascend”) as equity securities without readily determinable fair values. See Note 7 –Investments for further discussion of these investments.  

Our investments and ownership interests in entities in which we do not have a controlling financial interest are accounted for under the equity method of accounting if we have the ability to exercise significant influence over the entity. Investments accounted for under the equity method are initially recorded at cost, and the difference between the basis of our investment and the underlying equity in the net assets of the entity at the investment date, if any, is amortized over the lives of the related assets that gave rise to the difference.

In the event our ownership requires a disproportionate sharing of income or loss, we use the hypothetical liquidation at book value (“HLBV”) method to determine the appropriate allocation of income or loss. Under the HLBV method, income or loss of the investee is allocated based on hypothetical amounts that each investor would be entitled to receive if the net assets held were liquidated at book value at the end of each period, adjusted for any contributions made and distributions received during the period.

We hold equity method investments in AllDale Minerals III, LP (“AllDale III”) and NGP Energy Transition, L.P. (“NGP ET IV”). See Note 3 – Variable Interest Entities for further discussion of our equity method investments.

We review our investments for impairment whenever events or changes in circumstances indicate a loss in the value of the investment may be other-than-temporary.

Our investments in debt securities classified as available-for-sale are reported at fair value with unrealized gains and losses included in other comprehensive income in partners’ capital. Credit losses, if any, are recorded as an expense. Upon maturity or conversion, any associated unrealized gain or loss will be reclassified from other comprehensive income to our condensed consolidated income statement as a realized gain or loss. We hold debt securities in Ascend. See Note 7 – Investments for further discussion of this investment.

2.NEW ACCOUNTING STANDARDS

New Accounting Standards Issued and Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 primarily requires enhanced disclosures to (1) disclose specific categories in the rate reconciliation, (2) disclose the amount of income taxes paid and expensed disaggregated by federal, state, and foreign taxes, with further disaggregation by individual jurisdictions if certain criteria are met, and (3) disclose income (loss) from continuing operations before income tax (benefit) disaggregated between domestic and foreign. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. We do not expect ASU 2023-09 to have a material effect on our results of operations, cash flows and financial condition but will result in the enhanced disclosures described above.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”). ASU 2024-03 requires the disclosure of additional information about specific expense categories in the notes to the financial statements to provide enhanced transparency into the nature and function of expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. We

Table of Contents

continue to evaluate the impact of ASU 2024-03 on our results of operations, cash flows, financial condition and related disclosures.

3.VARIABLE INTEREST ENTITIES

AllDale I & II and Cavalier Minerals

We own the general partner interests and, including the limited partner interests we hold through our ownership in Cavalier Minerals JV, LLC (“Cavalier Minerals”), approximately 97% of the limited partner interests in AllDale Minerals LP (“AllDale I”) and AllDale Minerals II, LP (“AllDale II”, and collectively with AllDale I, “AllDale I & II”). As the general partner of AllDale I & II, we are entitled to receive 20.0% of all distributions from AllDale I & II with the remaining 80.0% allocated to limited partners based upon ownership percentages.

Cavalier Minerals owns approximately 72% of the limited partner interests in AllDale I & II. We own the managing member interest and a 96% member interest in Cavalier Minerals. Bluegrass Minerals Management, LLC (“Bluegrass Minerals”) owns a 4% member interest in Cavalier Minerals and a profits interest which entitles it to receive distributions equal to 25% of all distributions (including in liquidation) after all members have recovered their investment. All members have recovered their investment and Bluegrass Minerals began receiving its profits interest distributions in late 2022.

We have concluded that AllDale I, AllDale II and Cavalier Minerals are variable interest entities (“VIEs”) which we consolidate as the primary beneficiary because we have the power to direct the activities that most significantly impact the economic performance of AllDale I, AllDale II and Cavalier Minerals in addition to having substantial equity ownership.

Our share of Cavalier Minerals’ investment in AllDale I & II is eliminated in consolidation and Bluegrass Minerals’ investment in Cavalier Minerals is accounted for as noncontrolling ownership interest on our condensed consolidated balance sheets. Additionally, earnings attributable to Bluegrass Minerals are recognized as noncontrolling interest in our condensed consolidated statements of income.

The following table presents the carrying amounts and classification of AllDale I & II’s assets and liabilities included in our condensed consolidated balance sheets:

AllDale III

AllDale III owns oil & gas mineral interests in areas around the oil & gas mineral interests we own. Alliance Minerals owns a 13.9% limited partner interest in AllDale III. Alliance Minerals’ investment in AllDale III is subject to a 25% profits interest for the general partner that is subject to a return hurdle equal to the greater of 125% of cumulative capital contributions and a 10% internal rate of return, and following an 80/20 “catch-up” provision for the general partner.

We have concluded that AllDale III is a VIE that we do not consolidate. AllDale III is structured as a limited partnership with the limited partners (1) not having the ability to remove the general partner and (2) not participating significantly in operational decisions. We are not the primary beneficiary of AllDale III because we do not have the power to direct the activities that most significantly impact AllDale III’s economic performance. At June 30, 2025 and December 31, 2024, the carrying value of our investment in AllDale III was $21.6 million and $22.5 million, respectively.

NGP ET IV

On June 2, 2022, we committed to purchase $25.0 million of limited partner interests in NGP ET IV, a private equity fund sponsored by NGP and focused on investments that are part of the global transition toward a lower carbon economy. This commitment represents a 3.6% interest in NGP ET IV. As of June 30, 2025, we have funded $10.9 million of this commitment.  

We have concluded that NGP ET IV is a VIE that we do not consolidate. NGP ET IV is structured as a limited partnership with limited partners (i) not having the ability to remove the general partner and (ii) not participating significantly in operational decisions. We are not the primary beneficiary of NGP ET IV because we do not have the power to direct the activities that most significantly impact NGP ET IV’s economic performance. At June 30, 2025 and December 31, 2024, the carrying value of our investment in NGP ET IV was $8.0 million and $8.8 million, respectively.

Gavin Generation

In February 2025, we committed to invest up to $25.0 million of limited partner interests in Gavin Generation Holdings A, LP (“Gavin Generation”), which is sponsored by a private equity firm. Gavin Generation intends to own, indirectly, an interest in a joint venture holding company formed with a third party that plans to indirectly acquire, own and operate a coal-fired power plant. This commitment represents an interest of 5.4% in Gavin Generation (based on total commitments). Our investment in Gavin Generation is subject to a customary profit interest in favor of the general partner after the return of capital to the limited partners and the investment generating a specified internal rate of return in favor of the limited partners. On August 6, 2025, we funded $22.1 million of our $25.0 million capital commitment.

We have concluded that Gavin Generation is a variable interest entity that we do not consolidate. Gavin Generation is structured as a limited partnership with the limited partners (1) not having the ability to remove the general partner and (2) not participating significantly in operational decisions. We are not the primary beneficiary of Gavin Generation because we do not have the power to direct the activities that most significantly impact Gavin Generation's economic performance.

The fair value of our digital assets is based on an exchange quoted price.  See Note 6 – Digital Assets for more information on our digital assets.

The fair value measurement of our contingent consideration liability is determined using an option approach methodology simulation based on significant inputs not observable in active markets representing a Level 3 fair value measurement under the fair value hierarchy. Our contingent consideration liability is associated with our acquisition of our Hamilton County Coal, LLC (“Hamilton”) mine in 2015 wherein we agreed to pay the seller additional consideration for the acquisition if the average quarterly sales price exceeds a defined threshold price in any future quarters subject to a maximum of $110.0 million reduced for any payments made under an overriding royalty agreement with the sellers relating to mineral interests controlled by our Hamilton mine. We have paid $14.1 million under this contingent consideration agreement and $0.3 million under the overriding royalty agreement as of June 30, 2025.

The fair value measurement of our debt securities is determined using a combination of market approaches and option-pricing models which utilize significant inputs not observable in active markets representing a Level 3 fair value measurement under the fair value hierarchy. See Note 7 – Investments for additional information on our debt securities.

The estimated fair value of our long-term debt, including current maturities, is based on interest rates that we believe are currently available to us in active markets for issuance of debt with similar terms and remaining maturities. See Note 8 – Long-Term Debt for additional information on our long-term debt.

Quantitative Information about Level 3 Fair Value Measurements

Contingent Consideration

Our option approach methodology simulation for contingent consideration generates an expected payment for each quarter in Hamilton’s mine life by using proprietary internal estimates of our uncommitted coal sales prices and generating a simulated uncommitted coal sales price by applying unobservable inputs through a million simulations. This simulated coal sales price is then used in a calculation of the expected future payments using our proprietary committed coal sales prices and production for each quarter. We then calculate the present value of the estimated future payments. The following table presents quantitative information about certain significant unobservable inputs used in the fair value measurement for our contingent consideration liability. The use of significant unobservable inputs results in uncertainty as of the reporting date, as changes in these unobservable inputs could significantly raise or lower the estimated fair value.

Debt Securities

The fair value of our debt securities is determined using a combination of market approaches and option-pricing models. The underlying enterprise value is estimated using income and market approaches which utilize discounted cash flows and market participant values for assets in hypothetical sales scenarios. The enterprise value is then utilized in market approach models and option-pricing models taking into account the rights and preferences of the convertible notes, expected exit scenarios, and volatility associated with such outcomes to arrive at a fair value. The following table presents quantitative information about certain significant unobservable inputs used in the fair value measurement. The use of significant unobservable inputs results in uncertainty as of the reporting date, as changes in these unobservable inputs could significantly raise or lower the estimated fair value.

Infinitum

During 2022, we purchased shares of Series D Preferred Stock (“Series D Preferred Stock”) in Infinitum for $42.0 million. Infinitum is a Texas-based startup developer and manufacturer of electric motors featuring printed circuit board stators.  On September 8, 2023, we purchased $24.6 million of Series E Preferred Stock (“Series E Preferred Stock” and, together with the “Series D Preferred Stock,” the “Infinitum Preferred Stock”) in Infinitum.  The Infinitum Preferred Stock provides for non-cumulative dividends when and if declared by Infinitum’s board of directors. Each share of Infinitum Preferred Stock is convertible, at any time, at our option, into shares of common stock of Infinitum. We account for our ownership interest in Infinitum as an equity investment without a readily determinable fair value. Absent an observable price change, it is not practicable to estimate the fair value of our investment in Infinitum because of the lack of a quoted market price for our ownership interests.  Therefore, we use a measurement alternative other than fair value to account for our investment.

Ascend

On August 22, 2023, we purchased shares of Series D Preferred Stock (the “Ascend Series D Preferred Stock”) in Ascend for $25.0 million which was accounted for as an equity investment without a readily determinable fair value because of the lack of quoted market prices. Ascend is a U.S.-based manufacturer and recycler of sustainable, engineered battery materials for electric vehicles. In June 2025, Ascend raised new capital through a convertible note financing. Under the terms of the convertible note and the resulting recapitalization, all existing shares of each outstanding series of preferred stock were converted into common stock on a 1:1 basis for stockholders that participated in the convertible note purchase, or on a 3:1 basis if they did not participate.

We elected to participate in the recapitalization of Ascend with a $3.1 million commitment to purchase convertible debt. We have funded $2.1 million of our commitment as of June 30, 2025. The convertible notes provide for a redemption in two years for an amount equal to the greater of (a) a multiple of each stockholder’s investment in the convertible notes as determined by the level of participation or (b) the principal amount of each stockholder’s investment in the convertible notes plus an annual interest rate of 15%. Based on our level of participation, our convertible notes provide for a multiple of 12 times our funded commitment at redemption. We concluded that these convertible notes represent available-for-sale debt securities. We do not intend to sell our debt securities (which are subject to certain transfer restrictions) and believe it is likely that we will not be required to sell them before redemption. As a result of our participation in the recapitalization, our shares of Ascend Series D Preferred Stock converted into common stock on a 1:1 basis.

As discussed in Note 4 – Fair Value Measurements, we determined the fair value of the debt securities was $13.0 million. In the same models used to determine the value of the debt securities, we determined that the common stock we hold in Ascend as a result of the conversion had no value, resulting in an impairment charge of $25.0 million included in our condensed consolidated statements of income. The $25.0 million impairment charge is a Level 3 fair value measurement and is included within our Other, Corporate and Elimination category.

Credit Facility

On January 13, 2023, Alliance Coal, as borrower, entered into a Credit Agreement with various financial institutions which was amended on June 12, 2024 (the “Credit Agreement”).  The Credit Agreement provides for a $425.0 million revolving credit facility which includes a sublimit of $15.0 million for swingline borrowings and permits the issuance of letters of credit up to the full amount of the Credit Facility (the “Revolving Credit Facility”), and for a term loan in an aggregate principal amount of $75.0 million (the “Term Loan”). The Revolving Credit Facility also includes an incremental facility providing for an increase of $100.0 million at our option subject to lenders agreeing to participate in such incremental facility. The Credit Agreement matures on March 9, 2028, at which time the aggregate outstanding principal amount of all Revolving Credit Facility advances and all Term Loan advances are required to be repaid in full. Interest is payable quarterly, with principal on the Term Loan due in quarterly installments equal to 6.25% of the outstanding balance of the Term Loan on the Credit Agreement amendment date beginning with the quarter ended June 30, 2024.

The Credit Agreement is guaranteed by ARLP and certain of its subsidiaries, including the Intermediate Partnership and most of the direct and indirect subsidiaries of Alliance Coal (the “Subsidiary Guarantors”). The Credit Agreement also is secured by substantially all of the assets of the Subsidiary Guarantors and Alliance Coal. Borrowings under the Credit Agreement bear interest, at our option, at either (i) an adjusted one-month, three-month or six-month term rate based on the secured overnight financing rate published by the Federal Reserve Bank of New York, plus the applicable margin or (ii) the base rate plus the applicable margin. The base rate is the highest of (i) the Overnight Bank Funding Rate plus 0.50%, (ii) the Administrative Agent’s prime rate, and (iii) the Daily Simple Secured Overnight Financing Rate plus 100 basis points. The applicable margin for borrowings under the Credit Agreement are determined by reference to the Consolidated Debt to Consolidated Cash Flow Ratio. For borrowings under the Term Loan, we elected the one-month term rate, with applicable margin, which was 7.68% as of June 30, 2025.  At June 30, 2025, we had $41.0 million of letters of credit outstanding with $384.0 million available for borrowing under the Revolving Credit Facility. We incur an annual commitment fee of 0.50% on the undrawn portion of the Revolving Credit Facility. We utilize the Credit Agreement, as appropriate, for working capital requirements, capital expenditures and investments, scheduled debt payments and distribution payments.  

The Credit Agreement contains various restrictions affecting Alliance Coal and its subsidiaries, including, among other things, restrictions on incurrence of additional indebtedness and liens, sale of assets, investments, mergers and consolidations and transactions with affiliates. In each case, these restrictions are subject to various exceptions. In addition, restrictions apply to cash distributions by Alliance Coal to the Intermediate Partnership if such distribution would result in exceeding the debt of Alliance Coal to cash flow ratio (as determined in the Credit Agreement) being more than 1.0 to 1.0 or in Alliance Coal having liquidity of less than $200 million. The Credit Agreement requires us to maintain (a) a debt of Alliance Coal to cash flow ratio of not more than 1.5 to 1.0, (b) a consolidated debt of Alliance Coal and the Intermediate Partnership to cash flow ratio of not more than 2.5 to 1.0 and (c) an interest coverage ratio of not less than 3.0 to 1.0, in each case, during the four most recently ended fiscal quarters. The debt of Alliance Coal to cash flow ratio, consolidated debt of Alliance Coal and the Intermediate Partnership to cash flow ratio, and interest coverage ratio were 0.16 to 1.0, 1.00

Table of Contents

to 1.0 and 35.07 to 1.0, respectively, for the trailing twelve months ended June 30, 2025. We were in compliance with the covenants of the Credit Agreement as of June 30, 2025 and anticipate remaining in compliance with the covenants.  

8.625% Senior Notes due 2029

On June 12, 2024, the Intermediate Partnership and Alliance Resource Finance Corporation (as co-issuer), a wholly owned subsidiary of the Intermediate Partnership (“Alliance Finance”), issued an aggregate principal amount of $400.0 million of senior unsecured notes due 2029 (the “2029 Senior Notes”) in a private placement to qualified institutional buyers.  The 2029 Senior Notes have a term of five years, maturing on June 15, 2029 and accrue interest at an annual rate of 8.625%.  Interest is payable semi-annually in arrears on each June 15 and December 15. The 2029 Senior Notes are guaranteed, jointly and severally, on a senior unsecured basis by ARLP, certain of ARLP’s wholly owned oil and gas and coal royalties subsidiaries and each of ARLP’s subsidiaries that guarantee obligations under the Credit Agreement. The indenture governing the 2029 Senior Notes contains customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of distributions or similar restricted payments, undertaking transactions with affiliates and limitations on asset sales.

At any time prior to June 15, 2026, the issuers may redeem up to 35% of the aggregate principal amount of the 2029 Senior Notes at a redemption price equal to 108.625% of the principal amount redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, with an amount of cash not greater than the net proceeds from one or more equity offerings. The issuers may also redeem all or a part of the 2029 Senior Notes at any time on or after June 15, 2026, at the redemption prices set forth in the indenture, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. At any time prior to June 15, 2026, the issuers may redeem the 2029 Senior Notes at a redemption price equal to the principal amount plus a “make-whole” premium, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

In addition, if prior to June 15, 2026, a Specified Minerals Disposition (as defined in the indenture governing the 2029 Senior Notes and which involves oil and gas mineral interests) occurs, the issuers will be required to make an offer to purchase up to 40% of the aggregate principal amount of 2029 Senior Notes then outstanding at an offer price in cash in an amount equal to 108.625% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase.

Accounts Receivable Securitization

Certain direct and indirect wholly owned subsidiaries of our Intermediate Partnership are party to a $75.0 million accounts receivable securitization facility (“Securitization Facility”) which matures in January 2026. Under the Securitization Facility, certain subsidiaries sell certain trade receivables on an ongoing basis to our Intermediate Partnership, which then sells the trade receivables to AROP Funding, LLC (“AROP Funding”), a wholly owned bankruptcy-remote special purpose subsidiary of our Intermediate Partnership, which in turn borrows on a revolving basis up to $75.0 million secured by the trade receivables. After the sale, Alliance Coal, as servicer of the assets, collects the receivables on behalf of AROP Funding. The Securitization Facility bears interest based on a short-term bank yield index. On June 30, 2025, we had $14.8 million of letters of credit outstanding with $60.2 million available for borrowing under the Securitization Facility. The agreement governing the Securitization Facility contains customary terms and conditions, including limitations with regards to certain customer credit ratings.

February 2024 Equipment Financing

On February 28, 2024, Alliance Coal entered into an equipment financing arrangement accounted for as debt, wherein Alliance Coal received $54.6 million in exchange for conveying its interest in certain equipment owned indirectly by Alliance Coal and entering into a master lease agreement for that equipment (the “February 2024 Equipment Financing”). The February 2024 Equipment Financing contains customary terms and events of default and provides for forty-eight monthly payments with an implicit interest rate of 8.29%, maturing on February 28, 2028. Upon maturity, the equipment will revert to Alliance Coal.

(1)Our estimate of the liability for the present value of current workers′ compensation benefits is based on our actuarial calculations.  Our actuarial calculations are based on a blend of actuarial projection methods and numerous assumptions including claims development patterns, mortality, medical costs and interest rates.  The valuation loss in 2025 is due to a decrease in the discount rate from 5.17% on December 31, 2024 to 4.92% on June 30, 2025. The valuation gain in 2024 is due to an increase in the discount rate from 4.66% on December 31, 2023 to 5.18% on June 30, 2024.  

We limit our exposure to traumatic injury claims by purchasing a high deductible insurance policy that starts paying benefits after deductibles for a claim have been met.  The deductible level may vary by claim year.  Our workers’ compensation liability above is presented on a gross basis and does not include our expected receivables from our insurance policy.  Our receivables for traumatic injury claims under this policy as of June 30, 2025 are $3.7 million and are included in Other long-term assets on our condensed consolidated balance sheet.

11.CONTINGENCIES

Certain of our subsidiaries are party to litigation in which the plaintiffs allege violations of the Fair Labor Standards Act and state law due to alleged failure to compensate for time “donning” and “doffing” equipment and to account for certain bonuses in the calculation of overtime rates and pay. The plaintiffs in these cases sought class and collective action certification, which we opposed. In April 2024, we entered into a settlement agreement with the plaintiffs pursuant to which we agreed to settle such litigation for $15.3 million. Following preliminary approval of the settlement on July 10, 2025, we paid $15.3 million into an escrow account. A hearing in which the court will consider final approval of the settlement is scheduled for the fourth quarter of 2025. We believe our ultimate exposure, if any should litigation resume, will not be material to our results of operations or financial position; however, if our current belief as to the merit of the claims is not upheld if litigation were to resume, it is reasonably possible that the ultimate resolution of these matters could result in a potential loss that may be material to our results of operations.

We also have various other lawsuits, claims and regulatory proceedings incidental to our business that are pending against the ARLP Partnership. We record an accrual for a potential loss related to these matters when, in management’s opinion, such loss is probable and reasonably estimable. Based on known facts and circumstances, we believe the ultimate outcome of these outstanding lawsuits, claims and regulatory proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity. However, if the results of these matters are different from management’s current expectations and in amounts greater than our accruals, such matters could have a material adverse effect on our business and operations.

(1)The restricted units granted during 2025 have certain minimum-value guarantees per unit, regardless of whether the awards vest.
(2)During the six months ended June 30, 2025, we issued 366,043 unrestricted common units to the LTIP participants.  The remaining vested units were withheld to satisfy tax withholdings.

LTIP expense for grants of restricted units was $2.3 million for each of the three months ended June 30, 2025 and 2024 and $4.2 million and $4.4 million for the six months ended June 30, 2025 and 2024, respectively. The total obligation associated with LTIP grants of restricted units as of June 30, 2025 was $12.6 million and is included in the partners’ capital Limited partners-common unitholders line item on our condensed consolidated balance sheets.  As of June 30, 2025, there was $14.5 million in total unrecognized compensation expense related to the non-vested LTIP restricted unit grants that are expected to vest.  That expense is expected to be recognized over a weighted-average period of 1.5 years.

The effective income tax rates for our income tax expense for the three and six months ended June 30, 2025 and 2024 are less than the federal statutory rate, primarily due to the portion of income not subject to income taxes.

Our 2020 through 2024 tax years remain open to examination by tax authorities, and lower-tier partnership income tax returns for the tax years ended December 31, 2020 and 2021 are being audited by the Internal Revenue Service.

16.EARNINGS PER LIMITED PARTNER UNIT

We utilize the two-class method in calculating basic and diluted earnings per limited partner unit (“EPU”). Net income attributable to ARLP is allocated to limited partners and participating securities with nonforfeitable distributions or distribution equivalents, while net losses attributable to ARLP are allocated only to limited partners but not to participating securities. During 2025, our participating securities represent outstanding restricted unit awards under our LTIP. During 2024, our participating securities also included phantom units in notional accounts under our Supplemental Executive Retirement Plan (“SERP”) and the MGP Amended and Restated Deferred Compensation Plan for Directors (“Directors’ Deferred Compensation Plan”). The SERP and Directors’ Deferred Compensation Plan were terminated and settled in December 2024 and no longer have participating securities that receive an allocation of income.

(1)Diluted EPU gives effect to all potentially dilutive common units outstanding during the period using the treasury stock method. Diluted EPU excludes all potentially dilutive units calculated under the treasury stock method if their effect is anti-dilutive. For the three and six months ended June 30, 2025, participating securities of 605 and 715, respectively, were considered anti-dilutive under the treasury stock method. For the three and six months ended June 30, 2024, participating securities of 1,726 and 1,945, respectively, were considered anti-dilutive under the treasury stock method.

17.SEGMENT INFORMATION

We operate in the United States as a diversified natural resource company that generates operating and royalty income from the production and marketing of coal to major domestic utilities, industrial users and international customers as well as royalty income from oil & gas mineral interests. We aggregate multiple operating segments into four reportable segments, Illinois Basin Coal Operations, Appalachia Coal Operations, Oil & Gas Royalties and Coal Royalties. We also have an “all other” category referred to as Other, Corporate and Elimination. Our two coal operations reportable segments correspond to major coal producing regions in the eastern United States with similar economic characteristics including coal quality, geology, coal marketing opportunities, mining and transportation methods and regulatory issues. The two coal operations reportable segments include seven mining complexes operating in Illinois, Indiana, Kentucky, Maryland, Pennsylvania, and West Virginia and a coal loading terminal in Indiana on the Ohio River. Our Oil & Gas Royalties reportable segment includes our oil & gas mineral interests which are located primarily in the Permian (Delaware and Midland), Anadarko (SCOOP/STACK) and Williston (Bakken) basins. The operations within our Oil & Gas Royalties reportable segment primarily include receiving royalties and lease bonuses for our oil & gas mineral interests. Our Coal Royalties reportable segment includes coal mineral reserves and resources owned or leased by Alliance Resource Properties, which are either (a) leased to our mining complexes or (b) near our coal mining operations but not yet leased.

The Illinois Basin Coal Operations reportable segment includes (a) the Gibson County Coal, LLC’s mining complex, (b) the Warrior Coal, LLC mining complex, (c) the River View mining complex, which includes the River View and Henderson County mines and (d) the Hamilton mining complex. The segment also includes our Mt. Vernon Transfer Terminal, LLC (“Mt. Vernon”) coal loading terminal in Indiana which operates on the Ohio River, Mid-America Carbonates, LLC and other support services, and our non-operating mining complexes.      

The Appalachia Coal Operations reportable segment includes (a) the Mettiki mining complex, (b) the Tunnel Ridge, LLC mining complex and (c) the MC Mining complex.

The Oil & Gas Royalties reportable segment includes oil & gas mineral interests held by Alliance Minerals through its consolidated subsidiaries as well as equity interests held in AllDale III (Note 3 – Variable Interest Entities).

21

Table of Contents

The Coal Royalties reportable segment includes coal mineral reserves and resources owned or leased by Alliance Resource Properties that are (a) leased to certain of our mining complexes in both the Illinois Basin Coal Operations and Appalachia Coal Operations reportable segments or (b) located near our operations and external mining operations.

Other, Corporate and Elimination includes marketing and administrative activities, certain of our subsidiaries, primarily consisting of Matrix Design Group, LLC, its subsidiaries, and Alliance Design Group, LLC (collectively referred to as "Matrix Group"), Bitiki KY, LLC, which holds our crypto-mining activities (see Note 6 – Digital Assets), our non oil & gas equity investments (see Note 3 – Variable Interest Entities and Note 7 – Investments), Wildcat Insurance, LLC which assists the ARLP Partnership with its insurance requirements, AROP Funding and Alliance Finance (both discussed in Note 8 – Long-Term Debt). The eliminations included in Other, Corporate and Elimination primarily represent the intercompany coal royalty transactions described above between our Coal Royalties reportable segment and our coal operations’ mines.

Revenues included in Other, Corporate and Elimination are attributable to intercompany eliminations, which are primarily intercompany coal royalties eliminations, outside revenues at the Matrix Group and other outside miscellaneous sales and revenue activities.

(2)Segment Adjusted EBITDA Expense includes operating expenses, coal purchases, if applicable, and other income or expense as adjusted to remove certain items from operating expenses that we characterize as unrepresentative of our ongoing operations. Segment Adjusted EBITDA Expense is used as a financial measure by our management to assess the operating performance of our segments. Segment Adjusted EBITDA Expense is a key component of Segment Adjusted EBITDA in addition to coal sales, royalty revenues and other revenues. The exclusion of corporate general and administrative expenses from Segment Adjusted EBITDA Expense allows management to focus solely on the evaluation of segment operating performance as it primarily relates to our operating expenses.

(3)Other segment items include:

Oil & Gas Royalties – equity method investment income from AllDale III and income allocated to noncontrolling interest

(4)Segment Adjusted EBITDA is defined as net income attributable to ARLP before net interest expense, income taxes, depreciation, depletion and amortization and general and administrative expenses adjusted for certain items that we characterize as unrepresentative of our ongoing operations. Segment Adjusted EBITDA is used as a financial measure by Mr. Craft, who is also our chief operating decision maker (“CODM”), other management and by external users of our financial statements such as investors, commercial banks, research analysts and others. Our CODM uses Segment Adjusted EBITDA in assessing segment performance and deciding how to allocate resources. Segment Adjusted EBITDA provides useful information to our CODM and investors regarding our performance and results of operations because Segment Adjusted EBITDA (i) provides additional information about our core operating performance and ability to generate and distribute cash flow, (ii) provides investors with the financial analytical framework upon which we base financial, operational, compensation and planning decisions, (iii) presents a measurement that investors, rating agencies and debt holders have indicated is useful in assessing us and our results of operations and (iv) allows our CODM and management to focus solely on the evaluation of segment operating profitability as it relates to our revenues and operating expenses, which are primarily controlled by our segments.

Summary

We are a diversified natural resource company that generates operating and royalty income from the production and marketing of coal to major domestic utilities, industrial users and international customers, as well as royalty income from oil & gas mineral interests located in strategic producing regions across the United States. Our strategy is to provide our customers with reliable, baseload fuel for electricity generation to meet load expectations. The primary focus of our business is to maximize the value of our existing mineral assets, both in the production of coal from our mining assets and the leasing and development of our coal and oil & gas mineral ownership. In addition, we continue to position ourselves as a reliable energy provider for the future as we pursue opportunities that support the growth and development of energy and related infrastructure. We intend to pursue strategic investments that leverage our core competencies and relationships with electric utilities, industrial customers, and federal and state governments. We believe that our diverse and rich resource base and strategic investments will allow us to continue to create long-term value for unitholders.

We are the second largest coal producer in the eastern United States with seven operating underground mining complexes near many of the major eastern utility generating plants and on major coal hauling railroads in Illinois, Indiana, Kentucky, Maryland, Pennsylvania, and West Virginia, as well as a coal-loading terminal in Indiana. Two of our mines also have loading facilities located on the Ohio River.

In addition to our mining operations, Alliance Resource Properties owns or leases substantially all of our coal mineral resources and the majority of our coal mineral reserves in the Illinois and Appalachia Basins that are (a) leased to our internal mining complexes or (b) near our coal mining operations but not yet leased.

We currently own mineral interests in approximately 70,000 net royalty acres in premier oil & gas producing regions of the United States, primarily in the Permian (Delaware and Midland), Anadarko (SCOOP/STACK), and Williston (Bakken) basins, providing us with diversified exposure to industry-leading operators consistent with our general strategy to grow our oil & gas mineral interest business.

We have invested in energy and infrastructure opportunities including our investments in Infinitum Electric, Inc. (“Infinitum”), NGP Energy Transition, L.P. (“NGP ET IV”), and Ascend Elements, Inc. (“Ascend”) which are in the businesses of, respectively, electric motor manufacturing, private equity investments in renewable energy, the electrification of our economy or the efficient use of energy, and the manufacturing and recycling of sustainable, engineered battery materials for electric vehicles.

Total Revenues

Total revenues for the three months ended June 30, 2025 (“2025 Quarter”) decreased 7.7% to $547.5 million compared to $593.4 million for the three months ended June 30, 2024 (“2024 Quarter”) primarily as a result of reduced coal sales prices and lower transportation revenues, partially offset by increased coal sales volumes.

Coal sales decreased to $485.5 million for the 2025 Quarter compared to $512.7 million for the 2024 Quarter. The decrease was attributable to lower average coal sales prices, which reduced coal sales by $61.9 million, partially offset by higher tons sold, which increased coal sales by $34.7 million. Coal sales prices decreased by 11.3% as a result of lower domestic price realizations at several mines resulting from the continued roll-off of higher-priced legacy contracts. Coal sales volumes improved primarily driven by increased tons sold from our Hamilton and River View mines, partially offset by lower production levels at Tunnel Ridge due to challenging mining conditions.

Transportation revenues and expenses were $8.6 million and $26.7 million for 2025 and 2024 Quarters, respectively. The decrease of $18.1 million was primarily attributable to lower third-party transportation rates in the 2025 Quarter and decreased coal shipments for which we arrange third-party transportation.  Transportation revenues are recognized when title to the coal passes to the customer and recognized in an amount equal to the corresponding transportation expenses.

Segment Adjusted EBITDA Expense  

Segment Adjusted EBITDA Expense decreased 2.7% to $353.5 million primarily related to our coal operations which decreased 2.9% to $345.9 million, as a result of lower per ton costs, partially offset by higher coal sales volumes.  Segment Adjusted EBITDA Expense per ton sold for our coal operations decreased 9.0% to $41.27 per ton sold in the 2025 Quarter compared to $45.37 per ton in the 2024 Quarter, primarily due to an increased sales mix of tons from lower cost operations, improved recoveries at our River View and Hamilton mines and reduced longwall move days at Hamilton as well as the following per ton cost decreases:

Labor and benefit expenses per ton produced, excluding workers’ compensation, decreased 3.2% to $13.25 per ton in the 2025 Quarter from $13.69 per ton in the 2024 Quarter. The decrease of $0.44 per ton was primarily due to lower direct labor costs at several mines.

28

Table of Contents

Material and supplies expenses per ton produced decreased 13.2% to $13.90 per ton in the 2025 Quarter from $16.02 per ton in the 2024 Quarter. The decrease of $2.12 per ton produced primarily reflects decreases of $0.79 per ton for roof support, $0.65 per ton in longwall subsidence expense, $0.37 per ton for contract labor used in the mining process, and $0.18 per ton for safety related materials and supplies.

Maintenance expenses per ton produced decreased 12.0% to $4.64 per ton in the 2025 Quarter from $5.27 per ton in the 2024 Quarter. The decrease of $0.63 per ton produced was primarily a result of lower maintenance costs at several mines.

Production taxes and royalty expenses per ton incurred as a percentage of coal sales prices and volumes decreased $0.43 per produced ton sold in the 2025 Quarter compared to 2024 Quarter primarily as a result of lower price realizations and a favorable mix of tons sold that were mined in states without severance taxes.

Depreciation, depletion and amortization

Depreciation, depletion and amortization expense increased to $76.3 million for the 2025 Quarter compared to $66.5 million for the 2024 Quarter primarily as a result of increased coal sales volumes.

Change in fair value of digital assets

The change in the fair value of our digital assets increased by $16.6 million for the 2025 Quarter compared to the 2024 Quarter reflecting the movement in the price of bitcoin.

Impairment loss on investments

During the 2025 Quarter, we recorded a $25.0 million impairment on our equity investment in Ascend as a result of Ascend’s recent recapitalization through a convertible note financing completed during the 2025 Quarter.  Please read “Item 1. Financial Statements (Unaudited)—Note 7 – Investments” of this Quarterly Report on Form 10-Q for more information.

Net income attributable to ARLP  

Net income attributable to ARLP for the 2025 Quarter was $59.4 million, or $0.46 per basic and diluted limited partner unit, compared to $100.2 million, or $0.77 per basic and diluted limited partner unit, for the 2024 Quarter as a result of lower revenues, increased depreciation, and the impairment loss on investments in the 2025 Quarter, partially offset by an increase in the fair value of our digital assets.

Segment Adjusted EBITDA  

Our 2025 Quarter Segment Adjusted EBITDA decreased $19.7 million to $182.3 million from the 2024 Quarter Segment Adjusted EBITDA of $202.0 million.

Illinois Basin Coal Operations – Segment Adjusted EBITDA decreased 3.2% to $114.2 million in the 2025 Quarter from $118.0 million in the 2024 Quarter. The decrease of $3.8 million was primarily attributable to lower prices and higher operating expenses, partially offset by increased sales volumes. Coal sales price per ton decreased by 10.1% compared to the 2024 Quarter as a result of lower domestic price realizations at several mines in the region. Sales volumes increased by 15.2% compared to the 2024 Quarter due primarily to increased tons sold from our Hamilton and River View mines. Segment Adjusted EBITDA Expense increased 6.9% to $231.2 million in the 2025 Quarter from $216.2 million in the 2024 Quarter, primarily as a result of increased sales volumes, partially offset by lower operating expenses per ton.  Segment Adjusted EBITDA Expense per ton for the 2025 Quarter decreased by 7.1% compared to the 2024 Quarter due primarily to lower maintenance and materials and supplies costs at several mines in the region, improved recoveries at our River View and Hamilton mines and reduced longwall move days at Hamilton.

Appalachia Coal Operations – Segment Adjusted EBITDA decreased 35.1% to $29.4 million for the 2025 Quarter from $45.3 million in the 2024 Quarter. The decrease of $15.9 million was primarily attributable to lower coal sales, which decreased 21.6% to $141.6 million in the 2025 Quarter from $180.7 million in the 2024 Quarter, partially offset by reduced operating expenses. The decrease in coal sales reflects lower coal sales volumes and price realizations. Tons sold decreased by 16.8% in the 2025 Quarter compared to the 2024 Quarter primarily as a result of lower production levels at Tunnel Ridge due to challenging mining conditions. Average coal sales price per ton decreased by 5.8% compared to the 2024 Quarter primarily due to reduced domestic pricing from our Tunnel Ridge and MC Mining operations, partially offset by a greater mix of higher priced sales tons from MC Mining and Mettiki during the 2025 Quarter. Segment Adjusted

Total Revenues

Total revenues for the six months ended June 30, 2025 (“2025 Period”) decreased 12.6% to $1.09 billion compared to $1.25 billion for the six months ended June 30, 2024 (“2024 Period”) primarily due to lower coal sales and transportation revenues.

Coal sales decreased to $954.0 million for the 2025 Period compared to $1.07 billion for the 2024 Period. The decrease was attributable to lower average coal sales prices, which reduced coal sales by $96.4 million and lower tons sold, which reduced coal sales by $24.2 million. Coal sales prices decreased by 9.2% as a result of lower domestic price realizations at several mines resulting from the continued roll-off of higher-priced legacy contracts and reduced export price realizations from our MC Mining and Mettiki mines. Coal sales volumes decreased due primarily to lower production levels at Tunnel Ridge due to challenging mining conditions.

Transportation revenues and expenses were $18.8 million and $57.5 million for 2025 and 2024 Periods, respectively. The decrease of $38.7 million was primarily attributable to lower third-party transportation rates in the 2025 Period and decreased coal shipments for which we arrange third-party transportation.  Transportation revenues are recognized when title to the coal passes to the customer and recognized in an amount equal to the corresponding transportation expenses.

Segment Adjusted EBITDA Expense  

Segment Adjusted EBITDA Expense decreased 3.0% to $699.6 million primarily related to our coal operations which decreased 4.6% to $678.1 million, as a result of lower coal sales volumes and lower per ton costs.  Segment Adjusted EBITDA Expense per ton sold for our coal operations decreased 2.3% to $41.98 per ton sold in the 2025 Period compared to $42.99 per ton in the 2024 Period, primarily due to an increased sales mix of tons from lower cost operations, higher recoveries from several mines and fewer longwall move days at our Hamilton operation as well as the following per ton cost decreases:

Material and supplies expenses per ton produced decreased 11.2% to $13.70 per ton in the 2025 Period from $15.43 per ton in the 2024 Period. The decrease of $1.73 per ton produced primarily reflects decreases of $0.75 per ton for roof support, $0.46 per ton for contract labor used in the mining process, and $0.37 per ton in longwall subsidence expense.

Maintenance expenses per ton produced decreased 9.5% to $4.75 per ton in the 2025 Period from $5.25 per ton in the 2024 Period. The decrease of $0.50 per ton produced was primarily a result of lower maintenance costs at several mines.

Production taxes and royalty expenses per ton incurred as a percentage of coal sales prices and volumes decreased $0.40 per produced ton sold in the 2025 Period compared to the 2024 Period primarily as a result of lower price realizations, partially offset by an unfavorable mix of tons sold that were mined in states with severance taxes.

Depreciation, depletion and amortization

Depreciation, depletion and amortization expense increased to $145.0 million for the 2025 Period compared to $132.0 million for the 2024 Period primarily as a result of increased coal sales volumes at our River View mine and additional assets placed in service at our Tunnel Ridge and Mettiki operations during the 2025 Period.

Impairment loss on investments

During the 2025 Period, we recorded a $25.0 million impairment on our equity investment in Ascend as a result of Ascend’s recent recapitalization through a convertible note financing completed during the 2025 Period.  Please read “Item 1. Financial Statements (Unaudited)—Note 7 – Investments” of this Quarterly Report on Form 10-Q for more information.

Net income attributable to ARLP  

Net income attributable to ARLP for the 2025 Period was $133.4 million, or $1.03 per basic and diluted limited partner unit, compared to $258.2 million, or $1.98 per basic and diluted limited partner unit, for the 2024 Period as a result of lower revenues, higher depreciation, and the impairment loss on investments in the 2025 Period, partially offset by reduced operating expenses.

Segment Adjusted EBITDA  

Our 2025 Period Segment Adjusted EBITDA decreased $99.8 million to $362.8 million from the 2024 Period Segment Adjusted EBITDA of $462.6 million.

Illinois Basin Coal Operations – Segment Adjusted EBITDA decreased 6.9% to $240.4 million in the 2025 Period from $258.3 million in the 2024 Period. The decrease of $17.9 million was primarily attributable to lower coal sales prices, partially offset by higher sales volumes and lower operating expenses. Coal sales price per ton decreased by 7.3% compared to the 2024 Period as a result of lower domestic price realizations at several mines in the region. Sales volumes increased by 4.0% compared to the 2024 Period due primarily to increased tons sold from our Hamilton and River View mines. Segment Adjusted EBITDA Expense decreased 1.8% to $441.1 million in the 2025 Period from $449.3 million in the 2024 Period, primarily as a result of lower operating expenses per ton, partially offset by increased sales volumes.  Segment Adjusted EBITDA Expense per ton for the 2025 Period decreased by 5.5% compared to the 2024 Period due primarily to lower maintenance and materials and supplies costs at several mines in the region, improved recoveries at our River View and Hamilton mines and reduced longwall move days at Hamilton.

Appalachia Coal Operations – Segment Adjusted EBITDA decreased 62.3% to $45.0 million for the 2025 Period from $119.6 million in the 2024 Period. The decrease of $74.6 million was primarily attributable to lower coal sales, which decreased 25.6% to $276.9 million in the 2025 Period from $371.9 million in the 2024 Period, partially offset by lower operating expenses. The decrease in coal sales reflects lower coal sales volumes and price realizations. Tons sold decreased by 19.9% in the 2025 Period compared to the 2024 Period primarily as a result of lower production levels at Tunnel Ridge due to challenging mining conditions. Average coal sales price per ton decreased by 7.1% compared to the 2024 Period primarily due to reduced domestic pricing from our Tunnel Ridge and MC Mining operations and lower export price realizations from MC Mining and Mettiki, partially offset by a greater mix of higher priced sales tons from the MC Mining

and Mettiki operations during the 2025 Period. Segment Adjusted EBITDA Expense decreased 8.2% to $233.4 million in the 2025 Period from $254.3 million in the 2024 Period due to reduced volumes partially offset by increased per ton operating expenses. Segment Adjusted EBITDA Expense per ton for the 2025 Period increased by 14.6% compared to the 2024 Period due to challenging mining conditions at the Tunnel Ridge mine.

Oil & Gas Royalties – Segment Adjusted EBITDA decreased to $59.8 million in the 2025 Period compared to $62.7 million in the 2024 Period due to lower average sales price per BOE, which decreased 5.1%, partially offset by higher volumes, which increased 2.6%.

Coal Royalties – Segment Adjusted EBITDA decreased to $21.2 million in the 2025 Period compared to $22.4 million in the 2024 Period due to reduced average royalty rates per ton received from the Partnership’s mining subsidiaries.

Reconciliation of Non-GAAP Financial Measures

Segment Adjusted EBITDA  

We define Segment Adjusted EBITDA (a non-GAAP financial measure) as net income attributable to ARLP before net interest expense, income taxes, depreciation, depletion and amortization and general and administrative expenses adjusted for certain items that we characterize as unrepresentative of our ongoing operations. Segment Adjusted EBITDA is a key component of consolidated Adjusted EBITDA, which is used as a supplemental financial measure by management and by external users of our financial statements such as investors, commercial banks, research analysts and others. We believe that the presentation of consolidated Adjusted EBITDA provides useful information to investors regarding our performance and results of operations because Adjusted EBITDA, when used in conjunction with related GAAP financial measures, (i) provides additional information about our core operating performance and ability to generate and distribute cash flow, (ii) provides investors with the financial analytical framework upon which we base financial, operational, compensation and planning decisions and (iii) presents a measurement that investors, rating agencies and debt holders have indicated is useful in assessing us and our results of operations.

Segment Adjusted EBITDA is also used as a supplemental measure by our management for reasons similar to those stated in the previous explanation of Adjusted EBITDA. In addition, the exclusion of corporate general and administrative expenses from Segment Adjusted EBITDA allows management to focus solely on the evaluation of segment operating profitability as it relates to our revenues and operating expenses, which are primarily controlled by our segments.

passed through to our customers and, consequently, we do not realize any gain or loss on transportation revenues. Segment Adjusted EBITDA Expense is used as a supplemental financial measure by our management to assess the operating performance of our segments. Segment Adjusted EBITDA Expense is a key component of Segment Adjusted EBITDA in addition to coal sales, royalty revenues and other revenues. The exclusion of corporate general and administrative expenses from Segment Adjusted EBITDA Expense allows management to focus solely on the evaluation of segment operating performance as it primarily relates to our operating expenses. We also review Segment Adjusted EBITDA Expense on a per ton basis for cost trends at our coal operations by dividing Segment Adjusted EBITDA expense by coal sales volumes.

Liquidity and Capital Resources

Liquidity

We have historically satisfied our working capital requirements and funded our capital expenditures, investments, contractual obligations and debt service obligations with cash generated from operations, cash provided by the issuance of debt or equity, borrowings under credit and securitization facilities and other financing transactions. We believe that existing cash balances, future cash flows from operations and investments, borrowings under credit facilities and cash provided from the issuance of debt or equity will be sufficient to meet our working capital requirements, capital expenditures and additional investments, debt payments, contractual obligations, commitments and distribution payments. Nevertheless, our ability to satisfy our working capital requirements and additional investments, to satisfy our contractual obligations, to fund planned capital expenditures, to service our debt obligations or to pay distributions will depend upon our future operating performance and access to and cost of financing sources, which will be affected by prevailing economic conditions generally, and in both the coal and oil & gas industries specifically, as well as other financial and business factors, some of which are beyond our control. Based on our recent operating cash flow results, current cash position, anticipated future cash flows and sources of financing that we expect to have available, we anticipate being in compliance with the covenants of the Credit Agreement and expect to have sufficient liquidity to fund our operations and growth strategies. However, to the extent operating cash flow or access to and cost of financing sources are materially different than expected, future covenant compliance or liquidity may be adversely affected. Please read “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024.

Unit Repurchase Program

We have $80.6 million remaining authorized under our unit repurchase program as of June 30, 2025. No units were repurchased during the six months ended June 30, 2025. The program has no time limit and we may repurchase units from time to time in the open market or in other privately negotiated transactions. The unit repurchase program authorization does not obligate us to repurchase any dollar amount or number of units. The timing of any future unit repurchases and the ultimate number of units to be purchased will depend on several factors, including business and market conditions, our future financial performance, and other capital priorities. Please read “Part II - Item 2. Unregistered Sales of Equity Securities and Use of Proceeds” of this Quarterly Report on Form 10-Q for more information on the unit repurchase program.

Accounts Receivable Securitization

In January 2025, we extended the term of the accounts receivable securitization facility (the “Securitization Facility”) to January 2026. The borrowing availability under the facility is a maximum of $75.0 million. For additional information on the Securitization Facility, please see “Item 1. Financial Statements (Unaudited) – Note 8 – Long-Term Debt.”

Cash Flows

Cash provided by operating activities was $297.3 million for the 2025 Period compared to $425.4 million for the 2024 Period. The decrease in cash provided by operating activities was primarily due to the decrease in net income adjusted for non-cash items and unfavorable working capital changes primarily related to trade receivables and other miscellaneous changes. These decreases were partially offset by favorable working capital changes primarily related to inventories compared to the 2024 Period.

Net cash used in investing activities was $168.3 million for the 2025 Period compared to $223.0 million for the 2024 Period. The decrease in cash used in investing activities was primarily due to the decrease in capital expenditures in the 2025 Period as compared to the 2024 Period. This decrease was partially offset by a change in accounts payable and accrued liabilities during the 2025 Period.

Net cash used in financing activities was $211.2 million for the 2025 Period compared to $58.6 million for the 2024 Period. The increase in cash used in financing activities was primarily attributable to proceeds from the issuance of our 2029 Senior Notes and from an equipment financing in the 2024 Period. These increases were partially offset by reduced payments on long-term debt and reduced debt issuance costs in the 2025 Period.

Cash Requirements

Management anticipates having sufficient cash flow to meet 2025 cash requirements, including capital expenditures, scheduled payments on long-term debt, lease obligations, asset retirement obligation costs and workers’ compensation and pneumoconiosis costs, with our June 30, 2025 cash and cash equivalents of $55.0 million, cash flows from operations, or borrowings under our revolving credit facility and securitization facility, if necessary. We currently project average estimated annual maintenance capital expenditures over the next five years of approximately $7.28 per ton produced. Our anticipated total capital expenditures, including maintenance capital expenditures, for 2025 are estimated in a range of $285.0 million to $320.0 million. We will continue to have significant cash requirements over the long term, which may require us to incur debt or seek additional equity capital. The availability and cost of additional capital will depend upon prevailing market conditions, the market price of our common units and several other factors over which we have limited control, as well as our financial condition and results of operations.

Debt Obligations

See “Item 1. Financial Statements (Unaudited)—Note 8 – Long-Term Debt” of this Quarterly Report on Form 10-Q for a discussion of our long-term debt obligations.

We also have an agreement with a bank to provide additional letters of credit in the amount of $5.0 million to maintain surety bonds to secure certain asset retirement obligations and our obligations for workers’ compensation benefits.  On June 30, 2025, we had $5.0 million in letters of credit outstanding under this agreement.

Related-Party Transactions

We have related-party transactions and activities with Mr. Craft, MGP and their respective affiliates as well as other related parties. These related-party transactions and activities relate principally to (1) coal mineral leases with The Joseph W. Craft III Foundation and The Kathleen S. Craft Foundation, and (2) the use of aircraft. We also have related-party transactions with (a) WKY CoalPlay LLC, a company owned by entities related to Mr. Craft, regarding three mineral leases, and (b) entities in which we hold equity investments. For more information regarding our investments, please read “Item 1. Financial Statements (Unaudited)Note 7 Equity Investments” of this Quarterly Report on Form 10-Q.  Please read our Annual Report on Form 10-K for the year ended December 31, 2024, “Item 8. Financial Statements and Supplementary Data— Note 4 Acquisitions and Note 21 Related-Party Transactions” for additional information concerning related-party transactions.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk

We have significant long-term coal sales contracts. Most of the long-term sales contracts are subject to price adjustment provisions, which periodically permit an increase or decrease in the contract price, typically to reflect changes in specified indices or changes in production costs resulting from regulatory changes, or both.

In the past several years, global fossil fuel commodity prices have experienced periodic downturns and sustained volatility. Since being sworn into office, President Trump has issued numerous Executive Orders aimed to increase oil production and decrease commodity prices for consumers. For example, President Trump declared a “national energy emergency” in early January 2025, and gave the executive branch more power to expedite approvals for energy resource infrastructure (including coal, oil and gas). Additionally, President Trump’s “Unleashing American Energy” and “Reinvigorating America’s Beautiful Clean Coal Industry” Executive Orders incorporated numerous provisions aimed at unburdening and removing impediments to the development of various domestic energy resources, such as coal, oil and gas. In April 2025, President Trump signed an Executive Order that, among other matters, directed the U.S. Attorney General to investigate certain state laws that may adversely impact the development of energy resources, including state laws relating to climate change, environmental, social and governance initiatives, and funds collecting carbon penalties

37

Table of Contents

and/or taxes. We cannot predict what impact these Executive Orders or other executive actions may ultimately have on production or the prices we receive for our coal, oil and natural gas.

Our results of operations are highly dependent upon the prices we receive for our coal, oil and natural gas.  Regarding coal, the short-term sales contracts favored by some of our coal customers leave us more exposed to risks of declining coal price periods. Also, a significant decline in oil & gas prices would have a significant impact on our oil & gas royalty revenues.

We have exposure to coal and oil & gas sales prices and price risk for supplies used directly or indirectly in the normal course of coal and oil & gas production such as steel, electricity and other materials. We manage our risk for these items through strategic sourcing contracts for normal quantities required by our operations. Historically, we have not utilized any commodity price-hedges or other derivatives related to either our sales price or supply cost risks but may do so in the future.

Credit Risk

Most of our coal is sold to U.S. electric utilities or into the international markets through brokered transactions.  Therefore, our credit risk is primarily with domestic electric power generators and reputable global brokerage firms. Our policy is to independently evaluate each customer’s creditworthiness prior to entering into transactions and to constantly monitor outstanding accounts receivable. When deemed appropriate by our credit management department, we will take steps to reduce our credit exposure to customers that do not meet our credit standards or whose credit has deteriorated. These steps may include obtaining letters of credit or cash collateral, requiring prepayments for shipments or establishing customer trust accounts held for our benefit in the event of a failure to pay. Such credit risks from customers may impact the borrowing capacity of our Securitization Facility. See “Item 1. Financial Statements (Unaudited)—Note 8 – Long-Term Debt” of this Quarterly Report on Form 10-Q for more information on our Securitization Facility.

Exchange Rate Risk

Almost all our transactions are denominated in United States dollars, and as a result, we do not have material exposure to currency exchange-rate risks. However, because coal is sold internationally in United States dollars, general economic conditions in foreign markets and changes in foreign currency exchange rates may provide our foreign competitors with a competitive advantage. If our competitors’ currencies decline against the United States dollar or against foreign purchasers’ local currencies, those competitors may be able to offer lower prices for coal to these purchasers. Furthermore, if the currencies of overseas purchasers were to significantly decline in value in comparison to the United States dollar, those purchasers may seek decreased prices for the coal we sell to them. Consequently, currency fluctuations could adversely affect the competitiveness of our coal in international markets.

Interest Rate Risk

Borrowings under the Revolving Credit Facility and Securitization Facility are at variable rates and, as a result, we have interest rate exposure on any amounts drawn under these facilities. Historically, our earnings have not been materially affected by changes in interest rates and we have not utilized interest rate derivative instruments related to our outstanding debt. We did not have an outstanding balance under either the Revolving Credit Facility or the Securitization Facility at June 30, 2025.

There were no other changes in our quantitative and qualitative disclosures about market risk as set forth in our Annual Report on Form 10-K for the year ended December 31, 2024.

ITEM 4.CONTROLS AND PROCEDURES

We maintain controls and procedures designed to provide reasonable assurance that information required to be disclosed in the reports we file with the Securities and Exchange Commission (“SEC”) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.  As required by Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we have evaluated, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) of the Exchange Act)

38

Table of Contents

as of June 30, 2025.  Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that these controls and procedures are effective as of June 30, 2025.

During the quarterly period ended June 30, 2025, there have not been any changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified in connection with our evaluation that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

FORWARD-LOOKING STATEMENTS

Certain statements and information in this Quarterly Report on Form 10-Q, and certain oral statements made from time to time by our representatives, constitute “forward-looking statements.”  These statements are based on our beliefs as well as assumptions made by, and information currently available to, us.  When used in this document, the words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “foresee,” “may,” “outlook,” “plan,” “project,” “potential,” “should,” “will,” “would,” and similar expressions identify forward-looking statements.  Without limiting the foregoing, all statements relating to our future outlook, anticipated capital expenditures, future cash flows and borrowings, and sources of funding are forward-looking statements. These forward-looking statements are based on our current expectations and beliefs concerning future developments and reflect our current views with respect to future events and are subject to numerous assumptions that we believe are reasonable, but are open to a wide range of uncertainties and business risks, and actual results could differ materially from those discussed in these statements.  Among the factors that could cause actual results to differ from those in the forward-looking statements are:

decline in the coal industry’s share of electricity generation, including as a result of environmental concerns related to coal mining and combustion, the cost and perceived benefits of other sources of electricity and fuels, such as oil & gas, nuclear energy, and renewable fuels and the planned retirement of coal-fired power plants in the U.S.;

actions of the major oil-producing countries with respect to oil production volumes and prices and the direct and indirect impacts over the near and long term on oil & gas exploration and production operations at the properties in which we hold mineral interests;
changes in competition in domestic and international coal markets and our ability to respond to such changes;
potential shut-ins of production by the operators of the properties in which we hold oil & gas mineral interests due to low commodity prices or the lack of downstream demand or storage capacity;
risks associated with the expansion of and investments into the infrastructure of our operations and properties, including the timing of such investments coming online;
our ability to identify and complete acquisitions and to successfully integrate such acquisitions into our business and achieve the anticipated benefits therefrom;
our ability to identify and invest in new energy and infrastructure transition ventures;
the success of our development plans for Matrix Design, and our investments in emerging and other infrastructure and technology companies;
dependence on significant customer contracts, including renewing existing contracts upon expiration;
adjustments made in price, volume, or terms to existing coal supply agreements;
the effects of and changes in trade, monetary and fiscal policies and laws, and the results of central bank policy actions, including interest rates, bank failures, and associated liquidity risks;
the effects of and changes in taxes or tariffs and other trade measures adopted by the United States and foreign governments, including the imposition of or increase in tariffs on steel and/or other raw materials;
legislation, regulations, and court decisions and interpretations thereof, both domestic and foreign, including those relating to the environment and the release of greenhouse gases, such as the Environmental Protection Agency’s emissions regulations for coal-fired power plants, and state legislation seeking to impose liability on a wide range of energy companies under greenhouse gas “superfund” laws, mining, miner health and safety, hydraulic fracturing, and health care;
deregulation of the electric utility industry or the effects of any adverse change in the coal industry, electric utility industry, or general economic conditions;

PART II

OTHER INFORMATION

ITEM 1.LEGAL PROCEEDINGS

Litigation was initiated in November 2019 in the U.S. District Court for the Western District of Kentucky (Branson v. Webster County Coal, LLC, et al.) against certain of our subsidiaries in which the plaintiffs allege violations of the Fair Labor Standards Act and state law due to alleged failure to compensate for time “donning” and “doffing” equipment and to account for certain bonuses in the calculation of overtime rates and pay. A similar lawsuit was initiated in March 2020 in the U.S. District Court for the Eastern District of Kentucky (Brewer v. Alliance Coal, LLC, et al.). Subsequently, four additional lawsuits making similar allegations were initiated against certain of our subsidiaries: filed March 4, 2021 in the Circuit Court for Hopkins County, Kentucky (Johnson v. Hopkins County Coal, LLC, et al.); filed April 6, 2021 in the U.S. District Court for the Northern District of West Virginia (Rettig v. Mettiki Coal WV, LLC, et al.); filed April 9, 2021 in the U.S. District Court for the Southern District of Illinois (Cates v. Hamilton County Coal, LLC, et al.); and filed April 13, 2021 in the U.S. District Court for the Southern District of Indiana (Prater v. Gibson County Coal, LLC, et al.). The plaintiffs in these cases sought class and collective action certification, which we opposed. The plaintiffs sought to recover alleged compensatory, liquidated and/or exemplary damages for the alleged underpayment, and costs and fees that potentially may be recoverable under applicable law. In April 2024, we entered into a settlement agreement with the plaintiffs pursuant to which we agreed to settle all six cases for $15.3 million. Following preliminary approval of the settlement on July 10, 2025, we paid $15.3 million into an escrow account. A hearing in which the court will consider final approval of the settlement is scheduled for the fourth quarter of 2025. [If the settlement is not approved by the court,] we believe our ultimate exposure, if any should litigation resume, will not be material to our results of operations or financial position; however, if our current belief as to the merit of the claims in these lawsuits is not upheld if litigation were to resume, it is reasonably possible that the ultimate resolution of these matters could result in a potential loss that may be material to our results of operations.

ITEM 1A.RISK FACTORS

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors discussed in Part I - Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, which could materially affect our business, financial condition or future results. The risks described in these reports are not our only risks. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial based on current knowledge and factual circumstances, if such knowledge or facts change, also may materially adversely affect our business, financial condition and/or operating results in the future.  

ITEM 2.UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In January 2023, the board of directors authorized a $93.5 million increase to the unit repurchase program, which had $6.5 million of available capacity remaining of the original $100.0 million authorized at the time, authorizing us to be able to repurchase up to a total of $100.0 million of ARLP common units from that date. The unit repurchase program is intended to enhance ARLP’s ability to achieve its goal of creating long-term value for its unitholders and provides another means, along with quarterly cash distributions, of returning cash to unitholders. The program has no time limit and ARLP may repurchase units from time to time in the open market or in other privately negotiated transactions. The unit repurchase program authorization does not obligate ARLP to repurchase any dollar amount or number of units and repurchases may be commenced or suspended from time to time without prior notice.

During the three months ended June 30, 2025, we did not repurchase and retire any units. Since the inception of the unit repurchase program, we have repurchased and retired 6,390,446 units at an average unit price of $17.67 for an aggregate purchase price of $112.9 million.

ITEM 3.DEFAULTS UPON SENIOR SECURITIES
