Alliance Resource Partners, L.P. (NASDAQ: ARLP) today reported increased financial and operating results for the quarter and year ended December 31, 2021 (the "2021 Quarter" and "2021 Year", respectively) as compared to the quarter and year ended December 31, 2020 (the "2020 Quarter" and "2020 Year", respectively).

For the 2021 Quarter net income increased 48.0% to $51.8 million, or $0.40 per basic and diluted limited partner unit, compared to $35.0 million, or $0.27 per basic and diluted limited partner unit for the 2020 Quarter. Total revenues in the 2021 Quarter increased 29.2% to $473.5 million compared to $366.5 million in the 2020 Quarter as a result of higher coal sales volumes and prices, which rose 12.7% and 5.6%, respectively, as well as significantly higher oil & gas prices, which increased by 93.1%. Total operating expenses increased to $300.5 million in the 2021 Quarter, compared to $222.1 million in the 2020 Quarter, due to increased coal sales and production volumes, higher royalty and sales-related expenses as a result of increased coal price realizations, the impact of inflationary cost pressures and increased labor-related costs as certain mines worked overtime to meet customer demand. Increased operating expenses in the 2021 Quarter also reflect an $11.8 million buy-out of a coal contract that enabled us to make higher priced coal sales for delivery of tons through the first quarter of 2022 and $6.8 million of unfavorable year end non-cash actuarial and accrual adjustments. EBITDA also increased 7.3% in the 2021 Quarter to $130.2 million compared to $121.4 million in the 2020 Quarter. (Unless otherwise noted, all references in the text of this release to "net income (loss)" refer to "net income (loss) attributable to ARLP." For a definition of EBITDA and related reconciliation to its comparable GAAP financial measure, please see the end of this release.)

Results for the 2021 Year were also sharply higher as net income increased to $178.2 million, or $1.36 per basic and diluted limited partner unit, compared to a net loss of $129.2 million, or $(1.02) per basic and diluted limited partner unit for the 2020 Year. The increase in net income resulted from higher revenues, lower Segment Adjusted EBITDA expense per ton and lower depreciation in the 2021 Year and $157.0 million of non-cash impairment charges in the 2020 Year. Excluding the impact of impairment charges, net income for the 2021 Year of $178.2 million was an increase of $150.4 million compared to Adjusted net income of $27.8 million for the 2020 Year, while EBITDA increased 23.9% to $479.1 million in the 2021 Year compared to Adjusted EBITDA of $386.7 million for the 2020 Year. Coal sales volumes increased 14.4% and oil & gas prices rose by 88.2% in the 2021 Year to drive total revenues higher by 18.2% to $1.57 billion, compared to $1.33 billion for the 2020 Year. (For definitions of Adjusted net income, Adjusted EBITDA and Segment Adjusted EBITDA Expense and related reconciliations to comparable GAAP financial measures, please see the end of this release.)

As previously announced on January 28, 2022, the Board of Directors of ARLP’s general partner (the "Board") declared a cash distribution to unitholders of $0.25 per unit (an annualized rate of $1.00 per unit) for the 2021 Quarter, payable on February 14, 2022, to all unitholders of record as of the close of trading on February 7, 2022. The announced distribution represents a 25.0% increase over the cash distribution of $0.20 per unit for the quarter ended September 30, 2021 (the "Sequential Quarter").

"ARLP continued to benefit from favorable market conditions during the 2021 Quarter, posting significant increases over the 2020 Quarter to coal and oil & gas sales volumes, total revenues, net income and EBITDA," said Joseph W. Craft III, Chairman, President and Chief Executive Officer. "To meet our contractual commitments, our coal operations worked overtime to increase coal sales volumes by 606,000 tons and our marketing team’s efforts to capture the benefits of a rising market resulted in price realizations increasing by $2.54 per ton, both as compared to the Sequential Quarter. Favorable market conditions also allowed us to strengthen our contract book as we secured new agreements during the 2021 Quarter for the delivery of approximately 13.3 million tons through 2024. With these new contracts, ARLP enters 2022 with approximately 89% of its anticipated coal sales volumes priced and committed. Our royalties segments also delivered strong performance during the 2021 Quarter. Higher energy prices and increased royalty volumes resulted in our royalties businesses achieving a record EBITDA of $31.4 million."

Mr. Craft continued, "Higher natural gas and coal prices combined with a stronger export market were the primary factors that contributed to ARLP’s 2021 full year performance exceeding our initial expectations. During 2021, ARLP generated $302.2 million of free cash flow, reduced total debt and finance lease obligations by $161.5 million, improved total leverage to 0.93 times and increased liquidity by $105.4 million. Our Board elected to increase ARLP’s cash distribution to unitholders by 25.0%, consistent with the annualized distribution level set in April 2021 targeting approximately 30% of free cash flow before investments in growth opportunities."

ARLP's coal sales volumes increased in all regions compared to both the 2020 and Sequential Quarters. Higher export sales during the 2021 Quarter drove coal sales volumes higher by 15.3% and 7.2% in the Illinois Basin and Appalachian regions, respectively, compared to the 2020 Quarter. Compared to the Sequential Quarter, Illinois Basin coal sales volumes increased 10.1% in the 2021 Quarter primarily as a result of increased production at our River View, Warrior and Gibson South mines. Reflecting the spike in coal prices we secured in 2021, coal sales price per ton sold increased by 6.0% in both the Illinois Basin and Appalachian regions compared to the 2020 Quarter. Coal sales prices in the Illinois Basin increased by 10.0% compared to the Sequential Quarter due to improved price realizations at our Gibson South, Hamilton and River View operations. Total coal inventory fell to 0.6 million tons at the end of the 2021 Quarter, a decrease of 0.4 million tons compared to the end of the Sequential Quarter and comparable to the end of the 2020 Quarter.

Total Segment Adjusted EBITDA Expense per ton increased by 19.9% and 17.0% compared to the 2020 and Sequential Quarters, respectively. Both regions were impacted by inflationary pressures on numerous expense items, advance purchases of consumables to ensure adequate supply and mitigate the potential of future cost increases, lower recoveries at certain mining operations and higher labor-related expenses as discussed above. Segment Adjusted EBITDA expense per ton in the Illinois Basin also reflects the previously discussed contract buy-out expense and unfavorable non-cash actuarial and accrual adjustments recognized in the 2021 Quarter, which increased costs in the region by approximately $2.92 per ton sold. In Appalachia, Segment Adjusted EBITDA Expense per ton was also impacted by increased longwall subsidence expenses.

For our Oil & Gas Royalties segment, significantly higher sales price realizations per BOE and increased volumes in the 2021 Quarter drove Segment Adjusted EBITDA higher by 118.5% to $22.4 million compared to $10.2 million for the 2020 Quarter. Compared to the Sequential Quarter, Segment Adjusted EBITDA increased by $3.3 million in the 2021 Quarter due to higher volumes, which increased 10.6%, and continued strengthening of oil & gas prices, which rose by 6.5%.

Segment Adjusted EBITDA for our Coal Royalties segment increased to $9.9 million for the 2021 Quarter compared to $7.0 million and $9.2 million for the 2020 and Sequential Quarters, respectively, as a result of increased royalty tons sold and higher average royalty rates per ton.

Outlook

"The favorable market conditions that developed for oil, natural gas and coal during the second half of last year remain intact as we enter 2022," said Mr. Craft. "Through the end of 2021, coal-fired generation in our primary U.S. markets increased 20.9% year-over-year as total power demand increased 4.4% and high natural gas prices buoyed coal demand. Eastern coal generation would have been even stronger but for the industry-wide shortage of coal supply causing many utilities to lean on higher cost gas-fired generation in an effort to preserve coal stockpiles, which remain at critically low levels. Demand and pricing for U.S. coal in the export market continues to be attractive supported by increased power demand, high natural gas and LNG prices and a lack of global supply response along with supply disruptions. As reflected in our initial 2022 guidance below, we are optimistic ARLP will benefit from these market opportunities."

Mr. Craft continued, "Expectations for our royalty businesses also remain promising. The positive outlook for coal that I just discussed gives us confidence that steady growth from our coal royalties segment will continue during 2022. Similarly, the future looks bright for our oil & gas royalties segment. Oil, gas and natural gas liquids price realizations have increased significantly and the forward price curves remain strong. E&P operators are expected to continue to increase the pace of drilling and completion activity. We are now anticipating production from our acreage will continue to increase during 2022. During 2021, our oil & gas and coal royalties net income and EBITDA reached record levels and, as reflected in our initial guidance below, we anticipate that our royalty segments’ results will continue to increase in the future."

Reconciliation of GAAP "net income (loss) attributable to ARLP" to non-GAAP "Adjusted net income attributable to ARLP" (in thousands).

Adjusted net income attributable to ARLP is defined as net income (loss) attributable to ARLP modified for certain items that may not reflect the trend of future results, such as asset and goodwill impairments.

Adjusted net income attributable to ARLP should not be considered as an alternative to net income (loss) attributable to ARLP or any other measure of financial performance presented in accordance with GAAP. Adjusted net income attributable to ARLP excludes certain items that management believes affect the comparability of our operating results. This adjusted financial measure is used by our management and external users of our financial statements, such as investors, commercial banks, research analysts and others, to assess:

• our operational trends and performance relative to other coal and mineral companies;
• the comparability of our performance to earnings estimates provided by security analysts; and
• our performance excluding items which are generally nonrecurring in nature or whose timing or amount cannot be reasonably estimated.

We believe Adjusted net income attributable to ARLP is a useful measure for investors because it further demonstrates our financial performance without regard to items that may not reflect the trend of future results.

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

EBITDA is defined as net income (loss) attributable to ARLP before net interest expense, income taxes and depreciation, depletion and amortization and Adjusted EBITDA is EBITDA modified for certain items that may not reflect the trend of future results, such as asset and goodwill impairments. Distributable cash flow ("DCF") is defined as Adjusted 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, Adjusted EBITDA, DCF and DCR should not be considered as alternatives to net income (loss) attributable to ARLP, net income (loss), income (loss) from operations, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP. EBITDA, Adjusted 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, Adjusted EBITDA, DCF and DCR may not be the same method used to compute similar measures reported by other companies, or EBITDA, Adjusted 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. 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 "Adjusted EBITDA" to "Segment Adjusted EBITDA" (in thousands).

Segment Adjusted EBITDA Expense includes operating expenses, coal purchases and other 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 and 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. 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.

Segment Adjusted EBITDA is defined as net income (loss) attributable to ARLP before net interest expense, income taxes, depreciation, depletion and amortization, general and administrative expenses and asset and goodwill impairments. Segment Adjusted EBITDA – Coal Operations excludes the contribution of our Oil & Gas and Coal Royalties segments to allow management to focus solely on the operating performance of our Illinois Basin and Appalachia segments.
