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 March 31, 2024 and December 31, 2023 and the results of our operations, comprehensive income and cash flows for the three months ended March 31, 2024 and 2023. All intercompany transactions and accounts have been eliminated. Certain immaterial amounts in the prior quarter have been reclassified to conform to the current quarter presentation.

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, 2023.

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, 2024.

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

Digital Assets

We began our crypto-mining activities during the second half of 2020 as we started mining bitcoin as a pilot project to monetize already paid for, yet underutilized, electricity load. We continue to periodically be awarded digital assets through our crypto-mining activities. The awards are accounted for as revenue and valued at the exchange quoted price at the time they are awarded. Beginning January 1, 2024, with our adoption of the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-08, Intangibles - Goodwill and Other - Crypto Assets (Subtopic 350-60) ("ASU 2023-08"), the digital assets we hold are subsequently remeasured to fair value based on the exchange quoted price as of the balance sheet date and included on our condensed consolidated balance sheets within the Digital assets line item. The fair value of our digital assets are based on the exchange quoted price and represent a Level 1 input under the fair value hierarchy. The activity from remeasurement of digital assets to fair value is reflected in our condensed consolidated statements of income within the Change in fair value of digital assets line item. Digital assets sold for cash nearly immediately after they are awarded to us for mining activities are presented as cash flows from operating activities, while other sales are reflected as cash flows from investing activities in our condensed consolidated statements of cash flows. Our realized gains or losses are determined as the difference between the proceeds received when the digital assets are sold and our cost basis in the digital assets. Our cost basis is the value of the digital assets when they are awarded less any impairment recognized prior to our adoption of ASU 2023-08. We use a first-in, first-out methodology to assign costs to our digital assets in the calculation of our realized gains or losses. See Note 6 – Digital Assets for additional information.

2.NEW ACCOUNTING STANDARDS

New Accounting Standards Issued and Adopted

In December 2023, the FASB issued ASU 2023-08, Intangibles - Goodwill and Other - Crypto Assets (Subtopic 350-60) ("ASU 2023-08"), which requires an entity to measure certain digital assets at fair value with changes in the fair value recognized in net income. In addition, the guidance requires additional disclosures related to digital assets once adopted. We adopted ASU 2023-08, effective January 1, 2024, which resulted in a cumulative-effect adjustment to increase the opening balance of Partners' Capital of $6.2 million. See Note 6 – Digital Assets for more information on our digital assets.

New Accounting Standards Issued and Not Yet Adopted

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 primarily requires enhanced disclosures about significant segment expenses regularly provided to the chief operating decision maker ("CODM"), the amount and composition of other segment items, and the title and position of the CODM. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 with early adoption permitted. We are currently evaluating the impact of adopting ASU 2023-07, but do not expect it to have a material effect on our consolidated financial statements.

In December 2023, the FASB issued 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 are currently evaluating the impact of adopting ASU 2023-09, but do not expect it to have a material effect on our consolidated financial statements.

3.ACQUISITIONS

Acquisition Agreement

On January 27, 2023, we entered into a one-year collaborative agreement with a third party, effective January 1, 2023, committing up to $35.0 million for the acquisition of oil & gas mineral interests in the Midland and Delaware Basins. On February 19, 2024, we renewed this agreement for an additional one-year term, committing up to $25.0 million. Under

Table of Contents

the agreement, the third party assists us in the identification, evaluation, and acquisition of target oil & gas mineral interests. In exchange for these services, the third party receives a participation share, partially funded by the third party, and is paid a periodic management fee. During the three months ended March 31, 2024, we purchased $0.3 million and $0.1 million of oil & gas mineral interests in proved and unproved properties, respectively, pursuant to this agreement. Management fees paid under this agreement have been immaterial.

Miscellaneous Acquisitions

In addition to the acquisitions under the collaborative agreement discussed above, we purchased $0.3 million and $1.2 million of oil & gas mineral interests in proved and unproved properties, respectively, during the three months ended March 31, 2024.

4.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. 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. As a result of reaching this settlement, which is subject to court approval, we have accrued $15.3 million as of March 31, 2024. Our $15.3 million accrual is included in the Other current liabilities line item on our condensed consolidated balance sheet.

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 (if any), such matters could have a material adverse effect on our business and operations.

5.INVENTORIES

Inventories consist of the following:


	March 31,		December 31,
	2024		2023

	(in thousands)

Coal	$	88,108	$	56,549
Finished goods (net of reserve for obsolescence of $745 and $728, respectively)		4,174		3,908
Work in process		562		791
Raw materials		2,097		2,144
		94,941		63,392
Supplies (net of reserve for obsolescence of $7,719 and $7,439, respectively)		67,256		64,164
Total inventories, net	$	162,197	$	127,556

During the three months ended March 31, 2024, we recorded lower of cost or net realizable value adjustments of $7.3 million to our coal inventories. These adjustments are a result of lower coal sale prices and higher cost per ton primarily due to a longwall move at Hamilton County Coal, LLC ("Hamilton") and ongoing development activities at the Henderson County mine at our River View Coal, LLC ("River View") mining complex.

Certain of our subsidiaries, primarily consisting of Matrix Design Group, LLC, its subsidiaries, and Alliance Design Group, LLC (collectively referred to as "Matrix Group"), manufacture a variety of products for our mining operations and third parties. These products are primarily consumed internally by our mining operations with associated inventory historically presented as supplies inventory. Recently Matrix Group has been increasing its production of

Table of Contents

products with the intention to increase third-party sales. We have therefore presented our manufactured goods inventories in the table above separately from our historical presentation of supplies inventory.

6.DIGITAL ASSETS

The following table sets forth our digital assets as shown on the condensed consolidated balance sheet:


	March 31, 2024
	Units		Cost Basis		Fair Value

Digital assets:	(in thousands, except unit data)
Bitcoin		425.10	$	12,769	$	30,325
Total			$	12,769	$	30,325

The following table represents a reconciliation of the fair values of our digital assets:


	Three Months Ended
	March 31,
	2024
Digital assets:	(in thousands)
Beginning balance	$	15,811
Additions		3,604
Dispositions		(943)
Change in fair value gains		11,853
Ending balance	$	30,325

As discussed in Note 2 – New Accounting Standards, our beginning balance is inclusive of a cumulative-effect adjustment of $6.2 million as of January 1, 2024. Additions are the result of awarded digital assets received from our crypto-mining activities, while dispositions are the result of sales and payments for services. During the three months ended March 31, 2024, we had digital asset dispositions of $0.9 million, inclusive of realized gains of $0.6 million.

7.FAIR VALUE MEASUREMENTS

The following table summarizes our fair value measurements within the hierarchy not included elsewhere in these notes:


	March 31, 2024						December 31, 2023
	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3

	(in thousands)
Long-term debt	$	—	$	440,659	$	—	$	—	$	347,116	$	—

The carrying amounts for cash equivalents, accounts receivable, accounts payable, accrued and other liabilities approximate fair value due to the short maturity of those instruments.

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.

Credit Facility

On January 13, 2023, Alliance Coal, as borrower, entered into a Credit Agreement (the "Credit Agreement") with various financial institutions. The Credit Agreement provides for a $425 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 $425 million (the "Revolving Credit Facility"), and for a term loan in an aggregate principal amount of $75 million (the "Term Loan"). The Credit Agreement matures on March 9, 2027, 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. The Credit Agreement will instead mature on January 30, 2025, if on that date our Senior Notes, as discussed below, are still outstanding and Alliance Coal does not have liquidity of at least $200 million. Interest is payable quarterly, with principal on the Term Loan due in quarterly installments equal to 6.25% of the original principal amount of the Term Loan beginning with the quarter ending June 30, 2023 and the balance payable at maturity.

The Revolving Credit Facility is underwritten by a syndicate of eighteen financial institutions and the obligations of the lenders are individual obligations, which means the failure of one or more lenders to be able to fund its obligation does not relieve the remaining lenders from funding their obligations. Based on our diligence, including discussions with representatives of certain of these financial institutions, as of March 31, 2024 we have no reason to believe that the banks within our syndicate are facing financial difficulties, defaults or limited liquidity situations that would cause them to be unable to fund their obligations under the Credit Agreement. However, should any of the banks in our syndicate experience conditions in the future that limit their ability to fund their obligations, the amount available under the Revolving Credit Facility could be reduced.

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 three-month term rate, with applicable margin, which was 8.46% as of March 31, 2024. At March 31, 2024, we had $41.0 million of letters of credit outstanding with $384.0 million available for borrowing under the Revolving Credit Facility. We incurred 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.

Table of Contents

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 a minimum fixed charge coverage ratio (as determined in the Credit Agreement) 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 0.21 to 1.0, 0.59 to 1.0 and 59.18 to 1.0, respectively, for the trailing twelve months ended March 31, 2024. We were in compliance with the covenants of the Credit Agreement as of March 31, 2024 and anticipate remaining in compliance with the covenants.

Senior Notes

On April 24, 2017, 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 2025 ("Senior Notes") in a private placement to qualified institutional buyers. The Senior Notes have a term of eight years, maturing on May 1, 2025 and accrue interest at an annual rate of 7.5%. Interest is payable semi-annually in arrears on each May 1 and November 1. The indenture governing the 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.

Accounts Receivable Securitization

Certain direct and indirect wholly owned subsidiaries of our Intermediate Partnership are party to a $90.0 million accounts receivable securitization facility ("Securitization Facility") which matures in January 2025. 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 $90.0 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 March 31, 2024, we had $11.7 million of letters of credit outstanding with $33.3 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.

June 2020 Equipment Financing

On June 5, 2020, the Intermediate Partnership entered into an equipment financing arrangement accounted for as debt, wherein the Intermediate Partnership received $14.7 million in exchange for conveying its interest in certain equipment owned indirectly by the Intermediate Partnership and entering into a master lease agreement for that equipment (the "June 2020 Equipment Financing"). The June 2020 Equipment Financing contains customary terms and events of default and provides for forty-eight monthly payments with an implicit interest rate of 6.1%, maturing on June 5, 2024. Upon maturity, the equipment will revert to the Intermediate Partnership.

February 2024 Equipment Financing

On February 28, 2024, the Intermediate Partnership entered into an equipment financing arrangement accounted for as debt, wherein the Intermediate Partnership received $54.6 million in exchange for conveying its interest in certain equipment owned indirectly by the Intermediate Partnership 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 the Intermediate Partnership.

The effective income tax rates for our income tax expense for the three months ended March 31, 2024 and 2023 are less than the federal statutory rate, primarily due to the portion of income not subject to income taxes.

Our 2020 through 2023 tax years remain open to examination by tax authorities, and certain lower-tier partnership income tax returns for the tax years ended December 31, 2020 and 2021 are being audited by the Internal Revenue Service.

10.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.

AllDale III

AllDale Minerals III, LP ("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 because we are not the primary beneficiary and 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 the 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. See Note 11 – Equity Investments for more information about the accounting for our investment in AllDale III.

Francis

On April 5, 2022, we invested $20 million in Francis Renewable Energy, LLC ("Francis"), in the form of a convertible note. Our convertible note matured on April 1, 2023 and was converted into a preferred equity interest in Francis. Prior to conversion, we had determined the note more closely represented equity as opposed to debt. Therefore, we accounted for the convertible note as an equity contribution even though we did not participate in Francis' earnings or losses and were not eligible to receive distributions during the term of the note. Subsequent to the conversion on April 1, 2023, we participate in earnings and losses and are eligible to receive distributions. As of March 31, 2024, we held approximately 16.7% of Francis' equity.

We have concluded that Francis is a VIE that we do not consolidate because we are not the primary beneficiary and Francis' management structure is similar to a limited partnership with the non-managing members (i) not having the ability to remove the managing member and (ii) not participating significantly in the operational decisions. We are not the primary beneficiary of Francis because we do not have the power to direct the activities that most significantly impact Francis's economic performance. See Note 11 – Equity Investments for more information about the accounting for our investment in Francis.

NGP ET IV

On June 2, 2022, we committed to purchase $25.0 million of limited partner interests in NGP Energy Transition, L.P. ("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 March 31, 2023, we have funded $7.2 million of this commitment.

We have concluded that NGP ET IV is a VIE that we do not consolidate because we are not the primary beneficiary and 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 the 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. See Note 11 – Equity Investments for more information about the accounting for our investment in NGP ET IV.

Francis

We account for our ownership interest in the income or loss of Francis as an equity method investment. Prior to the conversion of our convertible note, we did not participate in Francis' earnings or losses; however, upon conversion on April 1, 2023 we began participating. As a development stage company, Francis depends primarily on capital contributions to meet its operating and debt obligations. We currently believe that the carrying value of our investment is recoverable; however, if Francis is unable to raise sufficient funds to continue its operations and meet its debt obligations, it could have an adverse effect on our investment.

Infinitum

During 2022, we purchased $42.0 million of Series D Preferred Stock ("Series D Preferred Stock") in Infinitum Electric, Inc. ("Infinitum"), 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

Table of Contents

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 $25.0 million of Series D Preferred Stock (the "Ascend Preferred Stock") in Ascend Elements, Inc. ("Ascend"), a U.S.-based manufacturer and recycler of sustainable, engineered battery materials for electric vehicles. The Ascend Preferred Stock provides for non-cumulative dividends when and if declared by Ascend's board of directors. Each share is convertible, at any time, at our option, into shares of common stock of Ascend. We account for our ownership interest in Ascend 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 Ascend 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.

Unit Repurchase Program

In January 2023, the board of directors of MGP authorized a $93.5 million increase to the unit repurchase program authorizing us to be able to repurchase up to a total of $100.0 million of ARLP common units from that date. No units were repurchased during the three months ended March 31, 2024. During the three months ended March 31, 2023, we repurchased and retired 860,060 units at an average unit price of $21.17 for an aggregate purchase price of $18.2 million. Since 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.

14.EARNINGS PER LIMITED PARTNER UNIT

We utilize the two-class method in calculating basic and diluted earnings per limited partner unit ("EPU"). Subsequent to the acquisition of oil & gas net royalty acres from JC Resources LP on February 22, 2023 (the "JC Resources Acquisition"), 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. Prior to the JC Resources Acquisition, in addition to limited partners and participating securities allocations, amounts were also allocated to our general partner for historical earnings from the mineral interests acquired in the JC Resources Acquisition.

Our participating securities are outstanding restricted unit awards under our Long-Term Incentive Plan ("LTIP") and 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 following is a reconciliation of net income attributable to ARLP used for calculating basic and diluted earnings per unit and the weighted-average units used in computing EPU:

18.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 and international utilities, and industrial users 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.

Table of Contents

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 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, LLC 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 11 – Equity Investments).

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. Approximately 64% of the coal sold by our coal operations' mines is leased from our Coal Royalties entities.

Other, Corporate and Elimination includes marketing and administrative activities, the Matrix Group, our investments in Francis, Infinitum, NGP ET IV, and Ascend (see Note 11 – Equity 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) and our crypto-mining activities. 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.

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.

The following is a reconciliation of Operating expenses (excluding depreciation, depletion and amortization), the most comparable GAAP financial measure, to consolidated Segment Adjusted EBITDA Expense:

Segment Adjusted EBITDA (a non-GAAP financial measure) is defined as net income attributable to ARLP before net interest expense, income taxes, depreciation, depletion and amortization and general and administrative expenses modified for certain items that we characterize as unrepresentative of our ongoing operations, such as the change in fair value of digital assets and litigation accruals. Segment Adjusted EBITDA is a key component of consolidated 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 EBITDA provides useful information to investors regarding our performance and results of operations because 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 financial measure by our management for reasons similar to those stated in the previous explanation of EBITDA. In addition, the exclusion of corporate general and administrative expenses from consolidated 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.

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 their load expectations. In addition, we continue to position ourselves as a reliable energy partner for the future as we pursue opportunities that support the advancement of energy and related infrastructure particularly in the face of expanding energy demand and the electrification of the economy. We intend to pursue strategic investments that leverage our core competencies and relationships with electric utilities, industrial customers, and federal and state governments.

We are currently the 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 oil & gas mineral interests in approximately 69,000 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 Francis Renewable Energy, LLC ("Francis"), 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 vehicle charging stations, 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.

On February 19, 2024, we renewed our collaborative agreement with a third-party to acquire oil & gas mineral interests in the Midland and Delaware Basins (the "Acquisition Agreement") for an additional one-year term, committing up to $25.0 million. For more information about the Acquisition Agreement please read "Item 1. Financial Statements (Unaudited)—Note 3 – Acquisitions" of this Quarterly Report on Form 10-Q.

Three Months Ended March 31, 2024 Compared to Three Months Ended March 31, 2023

Consolidated Information

Total Revenues

Total revenues for the three months ended March 31, 2024 ("2024 Quarter") decreased slightly to $651.7 million compared to $662.9 million for the three months ended March 31, 2023 ("2023 Quarter") primarily as a result of lower average coal sales prices, partially offset by higher oil & gas royalties and other revenues.

Total operating expenses

Total operating expenses increased to $491.4 million in the 2024 Quarter, compared to $455.6 million in the 2023 Quarter, primarily due to the sale of higher cost purchased coal, increased coal sales volumes, higher per ton costs on certain expense items discussed in more detail below and a $15.3 million litigation expense accrual in the 2024 Quarter relating to the settlement (which is subject to court approval) of certain litigation as described in "Part II - Item 1. Legal Proceedings" of this Quarterly Report on Form 10-Q.

Table of Contents

Net income attributable to ARLP

Net income for the 2024 Quarter was $158.1 million, or $1.21 per basic and diluted limited partner unit, compared to $191.2 million, or $1.45 per basic and diluted limited partner unit, for the 2023 Quarter as a result of lower revenues and increased total operating expenses, partially offset by an increase in the fair value of our digital assets.

Coal sales

Coal sales decreased to $561.9 million for the 2024 Quarter compared to $578.8 million for the 2023 Quarter. The decrease was attributable to lower average coal sales prices, which reduced coal sales by $30.9 million, partially offset by the benefit of higher tons sold, which contributed $14.0 million in additional coal sales. Coal sales prices decreased by 5.2% primarily due to reduced domestic pricing at our Tunnel Ridge mine, which benefited from significantly elevated pricing during the 2023 Quarter. Increased sales tonnage from our Hamilton and Warrior mines drove sales volumes higher by 2.4% in the 2024 Quarter to 8.7 million tons sold, compared to 8.5 million tons sold during the 2023 Quarter.

Coal - Segment Adjusted EBITDA Expense

Segment Adjusted EBITDA Expense for our coal operations increased 5.5% to $354.3 million, as a result of increased sales volumes and higher per ton costs. Segment Adjusted EBITDA Expense per ton sold for our coal operations increased 3.0% to $40.85 per ton sold in the 2024 Quarter compared to $39.66 per ton in the 2023 Quarter, primarily due to certain cost increases, which are discussed below by category:

●

Labor and benefit expenses per ton produced, excluding workers' compensation, increased 5.1% to $12.49 per ton in the 2024 Quarter from $11.88 per ton in the 2023 Quarter. The increase of $0.61 per ton was primarily due to higher direct labor costs at several mines.

●

Material and supplies expenses per ton produced increased 6.4% to $14.88 per ton in the 2024 Quarter from $13.99 per ton in the 2023 Quarter. The increase of $0.89 per ton produced primarily reflects increases of $0.35 per ton for outside expenses, $0.22 per ton for roof support and $0.11 per ton for environmental and reclamation expenses other than longwall subsidence.

●

Maintenance expenses per ton produced increased 17.6% to $5.22 per ton in the 2024 Quarter from $4.44 per ton in the 2023 Quarter. The increase of $0.78 per ton produced was primarily a result of higher maintenance costs at our River View and Hamilton mines.

●

We had outside coal purchases of $9.1 million in the 2024 Quarter compared to no sales of outside coal purchases in the 2023 Quarter. Thus, costs per ton in the 2024 Quarter increased as our cost of outside coal purchases are generally higher on a per ton basis than our produced coal.

For a definition of Segment Adjusted EBITDA Expense and related reconciliation to its comparable GAAP financial measure, please see "Item 1. Financial Statements (Unaudited) – Note 18 – Segment Information."

Change in fair value of digital assets

We recorded an $11.9 million increase in the fair value of our digital assets reflecting the increase in the price of bitcoin during the 2024 Quarter. Effective January 1, 2024, we adopted new accounting guidance which clarifies the accounting and disclosure requirements for certain crypto assets. The new guidance requires us to measure our digital assets at fair value and include the change in net income. Please see "Item 1. Financial Statements (Unaudited) – Note 6 – Digital Assets" for more information on our digital assets.

Segment Adjusted EBITDA

Our 2024 Quarter Segment Adjusted EBITDA decreased $31.3 million to $260.6 million from the 2023 Quarter Segment Adjusted EBITDA of $291.9 million.

Illinois Basin Coal Operations – Segment Adjusted EBITDA increased 6.3% to $140.3 million in the 2024 Quarter from $132.0 million in the 2023 Quarter. The increase of $8.3 million was primarily attributable to higher coal sales, which increased 10.0% to $370.6 million in the 2024 Quarter from $336.9 million in the 2023 Quarter, partially offset by increased operating expenses. The increase in coal sales reflects higher coal sales price realizations of $57.58 per ton sold in the 2024 Quarter compared to $54.43 per ton sold in the 2023 Quarter due to improved domestic pricing, and a 4.0% increase in tons sold due primarily to higher sales volumes from our Hamilton and Warrior mines. Segment Adjusted EBITDA Expense increased 12.6% to $233.1 million in the 2024 Quarter from $207.1 million in the 2023 Quarter primarily as a result of higher volumes and operating expenses per ton. Segment Adjusted EBITDA Expense per ton increased by 8.3% compared to the 2023 Quarter resulting from reduced production and recoveries at our River View mine.

Appalachia Coal Operations – Segment Adjusted EBITDA decreased 36.3% to $74.2 million for the 2024 Quarter from $116.6 million in the 2023 Quarter. The decrease of $42.4 million was primarily attributable to lower coal sales, which decreased 20.9% to $191.2 million in the 2024 Quarter from $241.9 million in the 2023 Quarter, partially offset by lower operating expenses. Average coal sales prices decreased by 19.4% compared to the 2023 Quarter as a result of reduced domestic pricing from our Tunnel Ridge mine, which benefited from significantly elevated pricing during the 2023 Quarter. Segment Adjusted EBITDA Expense decreased 6.6% to $117.5 million in the 2024 Quarter from $125.8 million in the 2023 Quarter due to decreased per ton operating expenses. Segment Adjusted EBITDA Expense per ton decreased by 4.8% compared to the 2023 Quarter due primarily to increased production and recoveries at our Mettiki mine during the 2024 Quarter.

Oil & Gas Royalties – Segment Adjusted EBITDA increased to $31.4 million in the 2024 Quarter compared to $30.0 million in the 2023 Quarter. Improved Segment Adjusted EBITDA in the 2024 Quarter was due to record oil & gas volumes, which rose to 898 MBOE sold in the 2024 Quarter, representing an increase of 18.3% compared to the 2023 Quarter as a result of increased drilling and completion activities on our interests and acquisitions of additional oil & gas mineral interests.

Coal Royalties – Segment Adjusted EBITDA increased to $12.4 million for the 2024 Quarter compared to $10.1 million for the 2023 Quarter. Higher average royalty rates per ton and increased royalty tons sold contributed to improved results for the 2024 Quarter.

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, 2023.

Accounts Receivable Securitization

In January 2024, we extended the term of the accounts receivable securitization facility (the "Securitization Facility") to January 2025 and increased the borrowing availability under the facility to $90.0 million. For additional information on the Securitization Facility, please see "Item 1. Financial Statements (Unaudited) – Note 8 – Long-Term Debt."

February 2024 Equipment Financing

Unit Repurchase Program

In May 2018, the Board of Directors approved the establishment of a unit repurchase program authorizing us to repurchase up to $100 million of ARLP common units. In January 2023, the board of directors of MGP authorized a $93.5 million increase to the unit repurchase program authorizing us to be able to repurchase up to a total of $100.0 million of ARLP common units from that date. 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. No units were repurchased during the three months ended March 31, 2024. 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.

Shelf Registration Statement

We currently have an effective universal shelf Registration Statement on Form S-3 that provides for the registration and sale of an unspecified amount of our equity or debt securities. We may over time, and subject to market conditions, in one or more offerings, offer and sell any of the securities described in the prospectus.

Table of Contents

Cash Flows

Cash provided by operating activities was $209.7 million for the 2024 Quarter compared to $221.7 million for the 2023 Quarter. 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 related to accounts payable, prepaid expenses and inventories. These decreases were partially offset by favorable working capital changes related to trade receivables, accrued payroll and related benefits as well as miscellaneous other changes compared to the 2023 Quarter.

Net cash used in investing activities was $120.5 million for the 2024 Quarter compared to $147.1 million for the 2023 Quarter. The decrease in cash used in investing activities was primarily due to acquisitions of oil & gas reserves including the JC Resources Acquisition in the 2023 Quarter. These decreases were partially offset by increased capital expenditures during the 2024 Quarter and changes in accounts payable and accrued liabilities during the 2024 Quarter.

Net cash used in financing activities was $15.0 million for the 2024 Quarter compared to $99.3 million for the 2023 Quarter. The decrease in cash used in financing activities was primarily attributable to increased borrowings under our revolving credit facility and the securitization facility, increased proceeds from equipment financing, reduced payments on long-term debt in the 2024 Quarter as compared to the 2023 Quarter, debt issuance costs paid in the 2023 Quarter and the purchase of units in the 2023 Quarter. These decreases were partially offset by payments under our revolving credit facility and the securitization facility in the 2024 Quarter and long-term debt borrowings in the 2023 Quarter.

Cash Requirements

Management anticipates having sufficient cash flow to meet 2024 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 March 31, 2024 cash and cash equivalents of $134.0 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 $7.76 per ton produced. Our anticipated total capital expenditures, including maintenance capital expenditures, for 2024 are estimated in a range of $450.0 million to $500.0 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 March 31, 2024, 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, (2) the use of aircraft, and (3) the purchase of oil & gas mineral interests from JC Resources LP, an entity owned by Mr. Craft. 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) with entities in which we hold equity investments. For more information regarding our investments, please read "Item 1. Financial Statements (Unaudited)—Note 11 – 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, 2023, "Item 8. Financial Statements and Supplementary Data— Note 3 – Acquisitions and Note 20 – Related-Party Transactions" for additional information concerning the JC Resources Acquisition and our 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.

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 that are used directly or indirectly in the normal course of coal and oil & gas production such as steel, electricity and other supplies. 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 had $45.0 million in borrowings under the Securitization Facility as of March 31, 2024, and no outstanding balance under the Revolving Credit Facility.

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, 2023.

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) as of March 31, 2024. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that these controls and procedures are effective as of March 31, 2024.

During the quarterly period ended March 31, 2024, 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.

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. The settlement is subject to court approval.

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, 2023, 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

On May 31, 2018, ARLP announced that the Board of Directors approved the establishment of a unit repurchase program authorizing ARLP to repurchase up to $100 million of its outstanding limited partner common units. In January 2023, the board of directors authorized a $93.5 million increase to the unit repurchase program 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 March 31, 2024, we did not repurchase and retire any units. Since 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
