Alliance Resource Partners, L.P. (NASDAQ: ARLP) ("ARLP" or the "Partnership") today reported substantial increases to financial and operating results for the quarter and year ended December 31, 2022 (the "2022 Quarter" and "2022 Full Year", respectively) compared to the quarter and year ended December 31, 2021 (the "2021 Quarter" and "2021 Full Year", respectively).

Total revenues in the 2022 Quarter increased 48.0% to a record $700.7 million compared to $473.5 million for the 2021 Quarter as a result of significantly higher coal sales and oil & gas royalties revenues. Increased revenues, partially offset by higher total operating expenses, led net income for the 2022 Quarter to a record $214.5 million, or $1.63 per basic and diluted limited partner unit, compared to $51.8 million, or $0.40 per basic and diluted limited partner unit, for the 2021 Quarter. EBITDA also increased 125.7% in the 2022 Quarter to $293.9 million compared to $130.2 million in the 2021 Quarter. (Unless otherwise noted, all references in the text of this release to "net income" refer to "net income attributable to ARLP." For a definition of EBITDA and related reconciliation to its comparable GAAP financial measure, please see the end of this release.)

2022 Full Year performance saw total revenues increase 53.3% to a record $2.4 billion compared to $1.6 billion for the 2021 Full Year, primarily due to substantial increases in prices and volumes from both ARLP’s coal operations and royalty segments. Higher revenues, partially offset by increased total operating and income tax expenses, led to significantly higher net income, which rose 224.0% to a record $577.2 million, or $4.39 per basic and diluted limited partner unit, compared to $178.2 million, or $1.36 per basic and diluted limited partner unit, for the 2021 Full Year. EBITDA increased 96.3% to $940.2 million compared to $479.1 million for the 2021 Full Year.

CEO Commentary

"ARLP’s record performance during the 2022 quarter and full year, in a supply and transportation constrained operating environment, is a testament to our team’s ability to execute and deliver reliable energy supply under challenging circumstances," commented Joseph W. Craft III, Chairman, President, and Chief Executive Officer. "In 2022, ARLP achieved its highest reported EBITDA and operating cash flow in the Partnership’s 23-year history, driven by continued growth in sales volumes coupled with higher price realizations across our coal operations and royalty segments."

Mr. Craft added, "With our strong balance sheet and relentless focus on cash flow generation, we are well positioned to capitalize on growth opportunities in the market and return capital to our unitholders. Based on our highly committed coal sales book and visibility into our end markets, last week we were pleased to announce a 40% increase in ARLP’s quarterly cash distribution rate to $0.70 per unit, or $2.80 per unit on an annualized basis. This increase is consistent with our long-term strategic capital allocation plans and is well-supported by strong visibility into future cash flows with approximately 94% of our expected 2023 coal sales volumes committed and priced as we enter the year. I am proud of the team’s record of success, and, as reflected in our initial guidance, look forward to achieving even stronger results in 2023."

Coal Operations

ARLP’s coal sales prices per ton increased significantly compared to the 2021 Quarter as improved price realizations in both the domestic and export markets drove coal sales prices higher by 38.0% and 67.7% in the Illinois Basin and Appalachia, respectively. Compared to the quarter ended September 30, 2022 (the "Sequential Quarter"), higher export prices led to an 11.7% increase in coal sales price realizations in the Illinois Basin while higher domestic prices primarily from our Tunnel Ridge mine resulted in an increase of 16.4% in Appalachian coal sales prices. Tons sold remained relatively consistent in the Illinois Basin compared to the 2021 Quarter while increasing by 9.0% in Appalachia due primarily to increased sales volumes from Tunnel Ridge as a result of higher recoveries. Compared to the Sequential Quarter, increased sales volumes from our Gibson South and River View mines resulted in 2.9% higher tons sold in the Illinois Basin. Coal sales volumes in Appalachia decreased by 1.8% compared to the Sequential Quarter due to higher sales from inventory at Tunnel Ridge in the Sequential Quarter. ARLP ended the 2022 Quarter with total coal inventory of 0.5 million tons, which included 0.2 million tons staged at ports for vessel export in early 2023.

Segment Adjusted EBITDA Expense per ton increased by 21.5% and 13.3% in the Illinois Basin and Appalachia, respectively, compared to the 2021 Quarter primarily as a result of ongoing inflationary pressures on certain expense items, most notably labor-related expenses, supply and maintenance costs, increased sales-related expenses due to higher price realizations, and $6.5 million of non-cash accruals for certain long-term liabilities. Also specific to the 2022 Quarter, a thermal event at our Hamilton mine resulted in an unexpected outage that lasted approximately four weeks. There were no injuries to personnel, no damage to the equipment, and mining operations returned to normal production levels in December 2022; however, third-party expenses related to the event were approximately $5.8 million and approximately 0.5 million tons of production was lost in the 2022 Quarter. Excluding certain non-cash liability accruals and the Hamilton event related expenses, Illinois Basin Segment Adjusted EBITDA Expense per ton for the 2022 Quarter would have been more in-line with the percentage increases realized in Appalachia for the 2022 Quarter.

Royalties

Segment Adjusted EBITDA for our Oil & Gas Royalties segment increased 44.1% to $32.2 million in the 2022 Quarter compared to $22.4 million in the 2021 Quarter primarily due to significantly higher oil & gas royalty volumes, which rose by 42.6% to a record 653,000 BOE sold as a result of increased drilling and completion activities and additional volumes from oil & gas mineral interest acquisitions completed during 2022. Compared to the Sequential Quarter, Segment Adjusted EBITDA decreased by 9.9% in the 2022 Quarter primarily due to lower price realizations, which decreased by 13.3%, partially offset by higher oil & gas volumes, which increased by 18.5%.

Segment Adjusted EBITDA for our Coal Royalties segment decreased 17.9% to $8.2 million for the 2022 Quarter compared to $9.9 million for the 2021 Quarter primarily related to the Hamilton thermal event which reduced royalty tons sold by 8.5%. Compared to the Sequential Quarter, Segment Adjusted EBITDA decreased 26.8% due to lower royalty tons sold and average royalty rates per ton due to the Hamilton thermal event.

Balance Sheet and Liquidity

In January 2023, the Partnership entered into a new $425.0 million senior secured revolving credit facility and $75.0 million term loan (the "Credit Facilities"), which will mature in March 2027, and renewed its $60.0 million accounts receivable securitization facility. The Credit Facilities will replace the previous revolving credit facility, which was set to mature in March 2024. More information regarding the Credit Facilities is provided in our Form 8-K filing made on January 20, 2023.

As of December 31, 2022, total debt and finance leases outstanding were $427.6 million, including $400.0 million in ARLP’s 2025 senior notes. The Partnership’s total and net leverage ratio improved to 0.45 times and 0.14 times, respectively, during the 2022 Quarter. ARLP ended the year with total liquidity of $762.8 million, which included $296.0 million of cash and cash equivalents and $466.7 million of borrowings available under our previous revolving credit and accounts receivable securitization facilities.

Distributions

As previously announced on January 27, 2023, the Board of Directors of ARLP’s general partner (the "Board") approved a cash distribution to unitholders for the 2022 Quarter of $0.70 per unit (an annualized rate of $2.80 per unit), payable on February 14, 2023, to all unitholders of record as of the close of trading on February 7, 2023. The announced distribution represents a 180.0% increase over the cash distribution of $0.25 per unit for the 2021 Quarter and is a 40.0% increase over the cash distribution of $0.50 per unit for the Sequential Quarter.

Unit Repurchase Program

ARLP also announced today that the Board has authorized an increase to the previously established unit repurchase program, which had $6.5 million of available capacity as of December 31, 2022. The expanded unit repurchase program authorizes ARLP to repurchase up to $100.0 million of its outstanding limited partner common units. The unit repurchase program announced today is intended to enhance ARLP’s ability to achieve its goal of creating long-term value for unitholders and, along with management’s objective of increasing quarterly cash distributions, increases flexibility in returning cash to unitholders. Future unit repurchases and distributions will be subject to ongoing Board review and authorization and will be based on a number of factors, including ARLP’s financial and operating performance and other capital requirements as well as future economic, business and market conditions.

The unit repurchase 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 its units and repurchases may be commenced or suspended from time to time without prior notice.

January 2023 Acquisition of Oil & Gas Royalties

On January 27, 2023, the Board approved an acquisition of 2,682 net oil and gas royalty acres in the Permian Basin from JC Resources LP, an entity owned by Mr. Craft, for a cash purchase price of $72.3 million, subject to customary closing adjustments. Upon closing, the acquisition is expected to be immediately accretive to cash flow. The purchase price will be funded with available cash and is expected to close within the next 30 days based on an effective date of January 1, 2023. Since the acquisition involves a related party, terms of the transaction were approved by the Board’s conflicts committee, which is comprised entirely of independent directors.

Outlook

"The supply driven energy crisis, Russia’s invasion of Ukraine and the steep build of inflation disrupted energy prices and placed a new emphasis on energy security in 2022," commented Mr. Craft. "Europe’s shift from Russian energy and U.S. and its allies’ economic sanctions are lowering Russian supply to the world, changing global energy trade routes and energy markets for several years to come, if not permanently. U.S. natural gas and coal exports should benefit in 2023 and beyond."

"Due in part to this ongoing disruption, ARLP is well positioned to achieve another record year in 2023 by increasing production and sales by one to two million tons and relying on our highly committed coal contract book and a favorable market outlook to deliver 13.0 to 17.0% higher realized pricing compared to 2022," commented Mr. Craft. "Even though natural gas prices have fallen recently due to the warm winter experienced so far, coal prices remain elevated in anticipation of international demand firming throughout the year as China’s economy reopens and as European markets look to replace 40 million tons of Russian coal imports received last year but unavailable this year. While the recent decline in natural gas prices are expected to impact our oil & gas royalties segment in the front half of the year, our coal segment should not be meaningfully affected due to our contracted position. In the back of this year and into 2024, we expect global economic activity will result in rising oil, gas and coal prices, and support our guidance."

Mr. Craft concluded, "We are beginning to see the significant inflation experienced last year start to level off, however labor pressures and higher sales related expenses as a result of higher price realizations and coal sales volumes will continue to add to our costs in 2023. However, we expect favorable market forces and our current coal sales commitments will drive top line growth that should more than offset these inflationary pressures as margins are expected to improve across our business in 2023 versus the prior year."

ARLP is providing the following initial 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 interest expense (before capitalized interest), interest income, income taxes and estimated maintenance capital expenditures. 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 and other income or expense. Transportation expenses are excluded as these expenses are passed through 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 excludes expenses of our Oil & Gas Royalties segment and is adjusted for intercompany interactions with our Coal Royalties segment.
