​ TULSA, OKLAHOMA, October 26, 2026 - Alliance Resource Partners, L.P. (NASDAQ: ARLP) ("we," "us," "our," "ARLP"or the"Partnership") today reported financial and operating results for the three and nine months ended September 30, 2026 (the "2026 Quarter"and"2026 Period," respectively). This release includes comparisons of results to the three and nine months ended September 30, 2025 (the "2025 Quarter"and"2025 Period,"respectively) and to the quarter ended June 30, 2026 (the"Sequential Quarter"). The use of "attributable to ARLP" indicates the exclusion of noncontrolling interests. For a definition of EBITDA, Adjusted EBITDA, Adjusted EBITDA attributable to ARLP and Segment Adjusted EBITDA Expense and related reconciliations to comparable GAAP financial measures, please see the end of this release. ​

● Total revenues in the 2026 Quarter increased 5.5% and 9.3% compared to the 2025 Quarter and Sequential Quarter, respectively, as a result of record oil & gas royalty revenues, increased coal sales volumes and higher other revenues, partially offset by lower coal sales price per ton.

● Net income attributable to ARLP increased 46.8% and 75.5% compared to the 2025 Quarter and Sequential Quarter, respectively, primarily as a result of higher total revenues and equity method investment income, lower operating expenses, a $16.5 million increase in the fair value of our digital assets and a $6.3 million gain recognized as a result of the remeasurement of our previously held equity investment in AllDale III in connection with the AllDale III & IV acquisition. Partially offsetting these increases were higher income tax expenses and a $7.3 million loss on the derivative instruments acquired in the AllDale III & IV acquisition.

● Adjusted EBITDA attributable to ARLP increased 26.3% and 26.4% compared to the 2025 Quarter and Sequential Quarter, respectively, primarily driven by higher Coal Operations Segment Adjusted EBITDA, the contribution from the AllDale III & IV acquisition and higher equity method investment income, partially offset by higher general and administrative expenses.

​ CEO Commentary "We had an outstanding third quarter led by our Coal Operations' strong shipping quarter combined with Hamilton being back on longwall production and River View and Tunnel Ridge operating well, which drove Segment Adjusted EBITDA at our Coal Operations 23.1% higher sequentially to $186.8 million, while Segment Adjusted EBITDA Expense per ton sold declined 13.1% year-over-year,"said Joseph W. Craft III, Chairman, President and Chief Executive Officer."The capital we have invested in our operations over the past several years is translating into a lower-cost, more reliable platform."Mr. Craft added,"In our first full quarter including AllDale III & IV, our Oil & Gas Royalties segment generated Segment Adjusted EBITDA attributable to ARLP of $43.6 million, up 16.8% sequentially and 61.4% year-over-year. The acquisition meaningfully increases the segment's contribution to ARLP's consolidated cash flows and expands our exposure to natural gas, which we believe will continue to benefit from growing LNG exports and rising power demand."

​ Segment Results and Analysis (Unaudited) ​ Coal Operations ​

(1) For definitions of Segment Adjusted EBITDA Expense and Segment Adjusted EBITDA and related reconciliations to comparable GAAP financial measures, please see the end of this release. Segment Adjusted EBITDA Expense per ton is defined as Segment Adjusted EBITDA Expense - Coal Operations (as reflected in the reconciliation table at the end of this release) divided by total tons sold.

● Illinois Basin tons sold increased 6.4% compared to the 2025 Quarter and 10.5% compared to the Sequential Quarter, driven by the resumption of longwall production at Hamilton following its extended longwall move.

● Appalachia tons sold increased 10.7% compared to the 2025 Quarter and 5.7% compared to the Sequential Quarter on strong sales at Tunnel Ridge.

● Coal sales price per ton in the Illinois Basin was in line with comparable periods, and in Appalachia decreased compared to the 2025 Quarter due to an increased sales mix of lower priced Tunnel Ridge volumes and lower sales price per ton at Tunnel Ridge and Mettiki.

● Segment Adjusted EBITDA Expense per ton in the Illinois Basin decreased 10.2% compared to the 2025 Quarter and 11.1% compared to the Sequential Quarter due to higher production at Hamilton and improved per ton costs at our River View operation.

● In Appalachia, Segment Adjusted EBITDA Expense per ton for the 2026 Quarter decreased 19.9% compared to the 2025 Quarter due to increased production at our Tunnel Ridge operation as well as a higher sales mix of lower-cost Tunnel Ridge volumes.

● Segment Adjusted EBITDA for our Total Coal Operations of $186.8 million increased 18.6% year-over-year and 23.1% sequentially, driven by higher Illinois Basin volumes and lower per ton costs.

● ARLP ended the 2026 Quarter with total coal inventory of 0.9 million tons, which was consistent with the end of the 2025 Quarter and represented a slight increase sequentially.

(2) Barrels of oil equivalent ("BOE") for natural gas volumes are calculated on a 6:1 basis (6,000 cubic feet of natural gas to one barrel).

(3) Average sales price per BOE is defined as oil & gas royalty revenues excluding lease bonus revenue divided by total BOE sold.

● On July 1, 2026, we completed the AllDale III & IV acquisition for approximately $206.2 million, adding control of approximately 48,500 net royalty acres across premier basins and resource plays including the Permian, Anadarko, Bakken and Haynesville.

● Oil & gas royalty volumes increased significantly in the 2026 Quarter compared to the 2025 Quarter and Sequential Quarter primarily due to the AllDale III & IV acquisition.

● Average sales price per BOE increased 15.5% compared to the 2025 Quarter on higher realized crude oil prices, partially offset by a higher natural gas volume mix following the AllDale III & IV acquisition. Compared to the Sequential Quarter, average sales price per BOE decreased 16.6%, primarily due to lower realized crude oil prices and a higher mix of natural gas volumes.

● Oil & Gas Royalties Segment Adjusted EBITDA attributable to ARLP was a quarterly record $43.6 million, increasing 61.4% and 16.8% compared to the 2025 Quarter and Sequential Quarter, respectively.

● Coal Royalties Segment Adjusted EBITDA of $18.2 million, increased 6.2% and 40.0% compared to the 2025 Quarter and Sequential Quarter, respectively, due to higher royalty tons sold, primarily from Tunnel Ridge and Hamilton.

Balance Sheet and Liquidity As of September 30, 2026, total debt and finance leases were outstanding in the amount of $679.9 million. The Partnership's total and net leverage ratios were 0.89 times and 0.78 times debt to trailing twelve months Adjusted EBITDA attributable to ARLP, respectively, as of September 30, 2026. ARLP ended the 2026 Quarter with total liquidity of $430.8 million, which included $84.8 million of cash and cash equivalents and $346.0 million of borrowings available under its revolving credit and accounts receivable securitization facilities. In addition, ARLP held 673 bitcoins valued at $56.3 million as of September 30, 2026. ​ Distributions ARLP announced today that the Board of Directors of ARLP's general partner approved a cash distribution to unitholders for the 2026 Quarter of $0.60 per unit (an annualized rate of $2.40 per unit), payable on November 13, 2026, to all unitholders of record as of the close of trading on November 6, 2026. The Distribution Coverage Ratio for the 2026 Quarter was 1.76x. Concurrent with this announcement, we are providing qualified notice to brokers and nominees that hold ARLP units on behalf of non-U.S. investors under Treasury Regulation Section 1.1446-4(b) and (d) and Treasury Regulation Section 1.1446(f)-4(c)(2)(iii). Brokers and nominees should treat one hundred percent (100%) of ARLP's distributions to non-U.S. investors as being attributable to income that is effectively connected with a United States trade or business. In addition, brokers and nominees should treat one hundred percent (100%) of the distribution as being in excess of cumulative net income for purposes of determining the amount to withhold. Accordingly, ARLP's distributions to non-U.S. investors are subject to federal income tax withholding at a rate equal to the highest applicable effective tax rate plus ten percent (10%). Nominees, and not ARLP, are treated as the withholding agents responsible for withholding on the distributions received by them on behalf of non-U.S. investors. ​ Outlook "We believe the fundamentals supporting coal demand continue to build,"Mr. Craft continued."Electricity load in the markets we serve is growing while permitting, interconnection and supply chain constraints are slowing the pace at which new generation can come online. We believe this dynamic will extend the runway for the existing coal fleet, with the impact becoming increasingly visible in our customers' coal burn as data center-driven demand materializes." "We continue to convert this constructive market into contracted volumes. During the quarter, we added 4.2 million committed and priced tons through 2028, and we are essentially fully committed at the midpoint of our 2026 sales volume guidance. With 31.7 million tons committed and priced for 2027, we enter next year with substantial visibility and the operating capacity to capture additional demand as commercial opportunities develop."Mr. Craft added,"Export markets have become a more meaningful component of our sales portfolio, with 3.7 million tons committed and priced for 2026 and 3.0 million tons for 2027. Market conditions remain dynamic, and we remain cautiously optimistic that additional export opportunities could provide upside to our sales volumes next year."Page 5 ​

Mr. Craft concluded,"In our Oil & Gas Royalties segment, if today's crude oil prices remain elevated, we could be in a position to have another record quarter to finish the year. Looking forward, we expect that 2027 results will compare favorably to 2026 due to the full-year contribution of minerals acquired this year as well as anticipated mineral investments next year to be funded by the segment's after-tax cash flow." ​
