Alliance Resource Partners, L.P. (NASDAQ: ARLP) ("ARLP" or the "Partnership") today reported increased financial and operating results for the quarter ended June 30, 2023 (the "2023 Quarter") compared to the quarter ended June 30, 2022 (the "2022 Quarter"). Total revenues in the 2023 Quarter increased 3.5% to $641.8 million compared to $619.9 million for the 2022 Quarter driven primarily by higher coal sales price per ton, which rose by 5.7%, partially offset by lower oil & gas royalty prices. Increased revenues, partially offset by higher total operating expenses, led to net income for the 2023 Quarter of $169.8 million, or $1.30 per basic and diluted limited partner unit, compared to $163.5 million, or $1.23 per basic and diluted limited partner unit, for the 2022 Quarter. (Unless otherwise noted, all references in the text of this release to "net income" refer to "net income attributable to ARLP.")

Compared to the quarter ended March 31, 2023 (the "Sequential Quarter"), total revenues in the 2023 Quarter decreased by 3.2% primarily as a result of lower average coal sales prices of $62.93 per ton sold compared to $68.34 per ton sold in the Sequential Quarter, partially offset by higher coal sales volumes, which rose 5.1% to 8.9 million tons sold in the 2023 Quarter. Lower revenues contributed to a reduction in net income and EBITDA of 11.2% and 8.0%, respectively, compared to the Sequential Quarter. (For a definition of EBITDA and related reconciliation to its comparable GAAP financial measure, please see the end of this release.)

Financial and operating results for the six months ended June 30, 2023 (the "2023 Period") increased compared to the six months ended June 30, 2022 (the "2022 Period"). Coal sales prices and coal sales revenues during the 2023 Period were higher by 21.8% and 23.8%, respectively, compared to the 2022 Period. Increased revenues and lower income tax expense, partially offset by higher total operating expenses, in the 2023 Period drove net income higher by 79.0% and EBITDA increased 29.6%, both as compared to the 2022 Period.

CEO Commentary

"ARLP delivered solid results during the second quarter of 2023, keeping us on track to deliver record financial results this year," commented Joseph W. Craft III, Chairman, President and Chief Executive Officer. "Continued strength in our contract book positioned our coal operations to achieve higher realized pricing per ton sold and Segment Adjusted EBITDA relative to the 2022 Quarter and the 2022 Period. Our year-to-date results have been impressive despite coal demand, both domestically and globally, being lower than we expected entering this year, due to slower economic growth, mild weather in our targeted markets, and lower natural gas prices."

Mr. Craft added, "Recent reports of sustained, record heat in many parts of the U.S. should once again emphasize our nation’s critical need for a reliable, affordable, and diverse energy mix. Markets can turn quickly in response to moderate swings in demand, particularly when supply remains constrained and policy decisions impact reliability. Our operations continue to provide a low-cost, secure source of supply for our customers, and with our recent actions to further strengthen our balance sheet, we expect to do so well into the future."

Segment Results and Analysis

Coal Operations

ARLP's coal sales prices per ton increased compared to the 2022 Quarter as improved domestic price realizations drove coal sales prices higher by 9.8% and 3.5% in the Illinois Basin and Appalachia, respectively. Compared to the Sequential Quarter, lower domestic and export prices led to a decrease of 24.1% in coal sales prices in Appalachia. Tons sold increased by 4.0% in the Illinois Basin compared to the 2022 Quarter due primarily to increased volumes from the Hamilton and Warrior mines. Appalachia coal sales volumes decreased by 8.5% compared to the 2022 Quarter as a result of reduced export sales across the region and lower production from our MC Mining operation. Compared to the Sequential Quarter, Illinois Basin coal sales volumes decreased 2.0% due to lower volumes from River View while coal sales volumes increased by 24.5% in Appalachia due to higher volumes from Tunnel Ridge as a result of longwall moves at the mine in the Sequential Quarter. ARLP ended the 2023 Quarter with total coal inventory of 1.8 million tons, representing an increase of 0.2 million tons and 0.5 million tons compared to the end of the 2022 and Sequential Quarters, respectively.

Segment Adjusted EBITDA Expense per ton increased by 6.0% in the Illinois Basin compared to the 2022 Quarter, resulting from higher labor-related expenses and maintenance costs as well as increased sales-related expenses due to higher price realizations. Segment Adjusted EBITDA Expense per ton in Appalachia increased by 11.1% compared to the 2022 Quarter, due primarily to increased labor-related expenses, purchased coal and higher inventory charges, partially offset by increased recoveries and lower selling expenses due to a greater mix of coal sales from operations in states with lower severance taxes per ton during the 2023 Quarter. Compared to the Sequential Quarter, Segment Adjusted EBITDA Expense per ton increased 5.8% in the Illinois Basin primarily due to reduced coal sales volumes from our lower cost Gibson South and River View mines during the 2023 Quarter. In Appalachia, Segment Adjusted EBITDA Expense per ton decreased 23.8% compared to the Sequential Quarter as a result of higher sales volumes from our lower cost Tunnel Ridge mine during the 2023 Quarter, increased recoveries across the region and longwall moves at Tunnel Ridge during the Sequential Quarter.

Royalties

Segment Adjusted EBITDA for the Oil & Gas Royalties segment decreased to $29.1 million in the 2023 Quarter compared to $37.6 million and $30.0 million in the 2022 and Sequential Quarters, respectively, primarily due to lower average sales prices per BOE, partially offset by higher BOE volumes sold. Higher BOE volumes during the 2023 Quarter compared to the 2022 Quarter resulted from increased drilling and completion activities on our interests and the acquisition of additional oil & gas mineral interests.

Segment Adjusted EBITDA for the Coal Royalties segment increased to $11.0 million for the 2023 Quarter compared to $9.1 million and $10.1 million for the 2022 and Sequential Quarters, respectively, as a result of higher average royalty rates per ton received from the Partnership's mining subsidiaries.

Balance Sheet and Liquidity

During the 2023 Quarter, ARLP repurchased $34.2 million of its senior notes due May 1, 2025 and began principal payments on its term loan. In July 2023, ARLP redeemed an additional $50.0 million of its senior notes.

As of June 30, 2023, total debt and finance leases outstanding were $417.8 million, including $339.2 million in ARLP's 2025 senior notes. The Partnership's total and net leverage ratio was 0.40 times and 0.14 times, respectively, as of June 30, 2023. ARLP ended the 2023 Quarter with total liquidity of $717.2 million, which included $284.9 million of cash and cash equivalents and $432.3 million of borrowings available under its revolving credit and accounts receivable securitization facilities.

Distributions

As previously announced, on July 28, 2023, the Board of Directors of ARLP's general partner (the "Board") approved a cash distribution to unitholders for the 2023 Quarter of $0.70 per unit (an annualized rate of $2.80 per unit), payable on August 14, 2023, to all unitholders of record as of the close of trading on August 7, 2023. The announced distribution represents a 75.0% increase over the cash distribution of $0.40 per unit for the 2022 Quarter and is consistent with the Sequential Quarter cash distribution.

Outlook

"The recent heat wave has supported additional coal burn this summer for both the domestic and export markets. However, until Henry Hub natural gas prices rise above $3.00 per million Btu, we do not expect any meaningful gas-to-coal switching domestically. Therefore, we have chosen to reduce our coal production and sales volume guidance for 2023. Production targets have been reduced at our River View and Gibson operations in the Illinois Basin and at our Mettiki operation in Appalachia," commented Mr. Craft. "Committed and priced sales tons currently represent 96% to 97% of our updated guidance range, and we plan to sell any remaining uncontracted tonnage primarily into international markets from these three mines. We have also adjusted the top end of our coal sales price per ton sold range downward based upon recent market analysis. On the positive side, we are lowering our cost estimates for the year as our team continues to find ways to reduce expenses in a stubbornly volatile inflationary environment."

Mr. Craft added, "During the 2023 Quarter, we agreed to sell an additional 8.6 million tons with multiple customers for coal to be delivered over the 2024 to 2026 time period. We expect there will be more opportunities this year to fill out our future contract book."

Mr. Craft closed, "These modest guidance revisions have not changed our view that we remain on track to achieve record financial results this year. As we look beyond 2023, we are encouraged by growth opportunities being pursued by our New Ventures group, the recent increase in the forward oil and gas price curves and acquisition prospects for our Oil & Gas Royalties segment. We are also seeing stability for coal demand over the next several years. Many of our coal customers are projecting significant growth in electricity demand as record numbers of new manufacturing facilities are being announced to come online over the next several years. All of these announced projects require exceptionally large electrical loads, adding to the reliability concerns of the stakeholders responsible for meeting the rising energy needs of their customers. The increased electricity demand should lead to slowing the pre-mature closing of coal-fired power plants in the eastern United States. We also expect the growth in LNG terminals coming online over the next five years will support higher domestic natural gas prices further supporting stable demand expectations for our coal operations over the next five to ten years."

ARLP is providing the following updated guidance for the 2023 full year:

Reconciliation of Non-GAAP Financial Measures

Reconciliation of GAAP "net income attributable to ARLP" to non-GAAP "EBITDA" and "Distributable Cash Flow" (in thousands).

EBITDA is defined as net income attributable to ARLP before net interest expense, income taxes and depreciation, depletion and amortization. Distributable cash flow ("DCF") is defined as EBITDA excluding equity method investment earnings, interest expense (before capitalized interest), interest income, income taxes and estimated maintenance capital expenditures and adding distributions from equity method investments. Distribution coverage ratio ("DCR") is defined as DCF divided by distributions paid to partners.

Management believes that the presentation of such additional financial measures provides useful information to investors regarding our performance and results of operations because these measures, when used in conjunction with related GAAP financial measures, (i) provide additional information about our core operating performance and ability to generate and distribute cash flow, (ii) provide investors with the financial analytical framework upon which management bases financial, operational, compensation and planning decisions and (iii) present measurements that investors, rating agencies and debt holders have indicated are useful in assessing us and our results of operations.

EBITDA, DCF and DCR should not be considered as alternatives to net income attributable to ARLP, net income, income from operations, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP. EBITDA and DCF are not intended to represent cash flow and do not represent the measure of cash available for distribution. Our method of computing EBITDA, DCF and DCR may not be the same method used to compute similar measures reported by other companies, or EBITDA, DCF and DCR may be computed differently by us in different contexts (i.e., public reporting versus computation under financing agreements).

Reconciliation of GAAP "Cash flows from operating activities" to non-GAAP "Free cash flow" (in thousands).

Free cash flow is defined as cash flows from operating activities less capital expenditures and the change in accounts payable and accrued liabilities from purchases of property plant and equipment. Free cash flow should not be considered as an alternative to cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP. Our method of computing free cash flow may not be the same method used by other companies. Free cash flow is a supplemental liquidity measure used by our management to assess our ability to generate excess cash flow from our operations.

Reconciliation of GAAP "Operating Expenses" to non-GAAP "Segment Adjusted EBITDA Expense" and Reconciliation of non-GAAP " EBITDA" to "Segment Adjusted EBITDA" (in thousands).

Segment Adjusted EBITDA Expense includes operating expenses, coal purchases, if applicable, and other income or expense. Transportation expenses are excluded as these expenses are passed on to our customers and, consequently, we do not realize any margin 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 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. Segment Adjusted EBITDA Expense – Coal Operations represents Segment Adjusted EBITDA Expense from our wholly-owned subsidiary, Alliance Coal, which holds our coal mining operations and related support activities.

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. Segment Adjusted EBITDA – Coal Operations represents Segment Adjusted EBITDA from our wholly-owned subsidiary, Alliance Coal, which holds our coal mining operations and related support activities and allows management to focus primarily on the operating performance of our Illinois Basin and Appalachia segments.
