Alliance Resource Partners, L.P. Reports First Quarter Financial and Operating Results; Declares Quarterly Cash Distribution of $0.60 Per Unit; and Updates 2026 Guidance

Total revenues decreased 4.5% to $516.0 million for the 2026 Quarter compared to $540.5 million for the 2025 Quarter primarily due to lower coal sales pricing, partially offset by record oil & gas royalty revenues and higher coal sales volumes. Net income for the 2026 Quarter was $9.1 million, or $0.07 per basic and diluted limited partner unit, compared to $74.0 million, or $0.57 per basic and diluted limited partner unit, for the 2025 Quarter. Net income was impacted by lower coal sales and higher depreciation, as well as an $11.6 million decrease in the fair value of our digital assets and a $37.8 million non-cash asset impairment charge in the 2026 Quarter due to ceasing longwall production and uncertainty regarding future operations at our Mettiki mine. Adjusted EBITDA decreased 3.1% to $155.0 million in the 2026 Quarter compared to $159.9 million in the 2025 Quarter.

Compared to the Sequential Quarter, total revenues decreased by 3.6% due to lower coal sales volumes and prices, partially offset by higher oil & gas royalty revenues. Net income decreased by 89.0% compared to the Sequential Quarter primarily due to lower production and lower coal sales volumes from our Hamilton mine as a result of a planned extended longwall move during the 2026 Quarter that led to higher per ton operating expenses. In addition, increased depreciation, non-cash asset impairment charges at Mettiki and lower investment income contributed to lower net income in the 2026 Quarter. Adjusted EBITDA for the 2026 Quarter decreased by 18.9% compared to the Sequential Quarter primarily due to higher costs at Hamilton and Mettiki.

CEO Commentary

"Most of our coal operations performed better than expected during the quarter, however meaningful weather-related shipment disruptions relating to Winter Storm Fern delayed sales volumes for the quarter," said Joseph W. Craft III, Chairman, President and Chief Executive Officer. "In the Illinois Basin, increased productivity at River View and Gibson South helped offset some of the impact of the planned extended longwall move at Hamilton. In Appalachia, Tunnel Ridge had production gains of approximately 28% compared to both the 2025 Quarter and the Sequential Quarter, while results at Mettiki reflected lower production and a non-cash impairment associated with ceasing longwall production and uncertainty regarding future operations as previously discussed."

Mr. Craft added, "We delivered another record quarter in our oil & gas royalties segment, driven by increased production volumes and higher oil prices. Increased drilling and completion activity across our core basins continues to validate the quality of our mineral portfolio, and for the second consecutive quarter, we expanded our portfolio, completing $16.2 million in acquisitions during the quarter. These results underscore the durability of our asset base and reinforce our disciplined approach to allocating capital to attractive, long-lived mineral interests. We believe our oil and gas royalties portfolio enhances our cash flow stability and long-term optionality across commodity cycles."

Coal Operations

Coal sales volumes decreased by 5.9% in the Illinois Basin compared to the Sequential Quarter due primarily to decreased tons sold from our Hamilton mine as a result of a planned extended longwall move during the 2026 Quarter. In Appalachia, tons sold increased by 3.6% and 8.0% compared to the 2025 Quarter and Sequential Quarter, respectively, primarily as a result of fewer production days in the prior periods at our Tunnel Ridge mine due to longwall moves. Coal sales price per ton sold decreased by 7.4% in the Illinois Basin compared to the 2025 Quarter as a result of the expiration of higher priced legacy contracts. In Appalachia, coal sales price per ton sold decreased by 4.8% and 11.1% compared to the 2025 Quarter and Sequential Quarter, respectively, primarily due to an increased sales mix of lower priced Tunnel Ridge sales volumes in the 2026 Quarter and reduced domestic sales price per ton. ARLP ended the 2026 Quarter with total coal inventory of 1.2 million tons, representing a decrease of 0.2 million tons and an increase of 0.1 million tons compared to the end of the 2025 Quarter and Sequential Quarter, respectively.

Segment Adjusted EBITDA Expense per ton in the Illinois Basin increased 3.4% compared to the Sequential Quarter due primarily to the planned extended longwall move at our Hamilton mine during the 2026 Quarter. In Appalachia, Segment Adjusted EBITDA Expense per ton for the 2026 Quarter decreased by 10.8% compared to the 2025 Quarter as a result of increased production at our Tunnel Ridge operation primarily as a result of fewer production days due to the longwall moves in the 2025 Quarter.

Royalties

Segment Adjusted EBITDA for the Oil & Gas Royalties segment increased to $34.6 million in the 2026 Quarter compared to $29.9 million and $30.0 million in the 2025 Quarter and Sequential Quarter, respectively, due to record oil & gas royalty volumes, which increased 16.1% and 3.3%, respectively, as a result of increased drilling and completion activities on our interests and acquisitions of additional oil & gas mineral interests. Improved commodity pricing also contributed to the increase in Segment Adjusted EBITDA compared to the Sequential Quarter.

Segment Adjusted EBITDA for the Coal Royalties segment increased to $12.3 million in the 2026 Quarter compared to $9.4 million in the 2025 Quarter due to higher royalty tons sold, primarily from Tunnel Ridge, partially offset by lower average royalty rates per ton received from the Partnership's mining subsidiaries. Compared to the Sequential Quarter, Segment Adjusted EBITDA for the Coal Royalties segment decreased 15.7%, primarily reflecting lower realized royalty rates per ton.

Balance Sheet and Liquidity

As of March 31, 2026, total debt and finance leases were outstanding in the amount of $507.7 million. The Partnership’s total and net leverage ratios were 0.73 times and 0.69 times debt to trailing twelve months Adjusted EBITDA, respectively, as of March 31, 2026. ARLP ended the 2026 Quarter with total liquidity of $431.2 million, which included $28.9 million of cash and cash equivalents and $402.3 million of borrowings available under its revolving credit and accounts receivable securitization facilities. In addition, ARLP held 618 bitcoins valued at $42.2 million as of March 31, 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 May 15, 2026, to all unitholders of record as of the close of trading on May 8, 2026.

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

"Looking ahead, contracting activity with domestic utility customers for 2026 has remained active, though the pace has varied as some customers continue to evaluate summer burn requirements," commented Mr. Craft. "During the quarter, the Iran conflict briefly reopened U.S. thermal coal export activity in early March, enabling us to enter into contracts for 1.8 million tons to be delivered in 2026 and 2027. In addition, we sold an additional 0.5 million tons to domestic customers, bringing our sales book to more than 95% committed and priced for 2026 assuming production comes in at the midpoint of our guidance range. Our remaining open position is concentrated in the second half of 2026, where additional commitments will depend on summer burn and customer requirements. More broadly, we continue to see a constructive demand backdrop as growing power demand, particularly from data centers, reinforces the importance of reliable baseload generation."

Mr. Craft continued, "We expect first quarter shipment disruptions tied to Winter Storm Fern and subsequent high-water conditions to be recovered over the balance of the year. In addition, once the planned longwall moves at Hamilton and Tunnel Ridge are completed in the second quarter, we do not expect any further longwall moves in 2026, which should improve operating visibility for the back half of the year."

Mr. Craft concluded, "Based on year-to-date outperformance of our oil & gas royalties, we are increasing our volume guidance for the segment. Recent strength and volatility in crude oil prices have increased the near-term outlook and, because our current portfolio is unhedged, changes in market prices are reflected directly in our realized pricing. If current market conditions persist, we would expect realized BOE prices to be higher than last year, contributing to stronger segment results."
