Alliance Resource Partners, L.P. (NASDAQ: ARLP) today reported increased financial and operating results for the quarter ended June 30, 2021 (the "2021 Quarter") compared to the quarter ended March 31, 2021 (the "Sequential Quarter"). Led by higher coal sales volumes and oil & gas prices, ARLP’s total revenues increased 13.8% to $362.4 million, net income jumped 77.9% to $44.0 million and EBITDA rose 25.7% to $118.6 million, all as compared to the Sequential Quarter. For our coal operations, increased sales tons led coal sales revenues and Segment Adjusted EBITDA higher by 13.4% and 25.7%, respectively, compared to the Sequential Quarter. Our royalties segments also reported improved results compared to the Sequential Quarter, as higher sales price realizations per BOE and increased coal royalty tons sold drove total royalty revenues and Segment Adjusted EBITDA up by 15.5% and 15.3%, respectively. (Unless otherwise noted, all references in the text of this release to "net income (loss)" refer to "net income (loss) attributable to ARLP." For definitions of EBITDA and Segment Adjusted EBITDA and related reconciliations to comparable GAAP financial measures, please see the end of this release.)

Financial and operating results for the 2021 Quarter and the six months ended June 30, 2021 (the "2021 Period") were significantly improved compared to the quarter ended June 30, 2020 (the "2020 Quarter") and the six months ended June 30, 2020 (the "2020 Period"), which were impacted by reduced global energy demand and weak commodity prices as a result of lockdown measures imposed in response to the COVID-19 pandemic.

Increased coal sales volumes and oil & gas prices drove total revenues higher in the 2021 Quarter by 42.0% to $362.4 million, compared to $255.2 million for the 2020 Quarter. Higher revenues, partially offset by increased operating expenses, led net income to jump by $90.7 million to $44.0 million for the 2021 Quarter, or $0.34 per basic and diluted limited partner unit, compared to a net loss of $46.7 million, or $(0.37) per basic and diluted limited partner unit, for the 2020 Quarter. EBITDA also increased 145.9% in the 2021 Quarter to $118.6 million compared to $48.2 million in the 2020 Quarter.

Net income for the 2021 Period increased $260.2 million to $68.8 million, or $0.53 per basic and diluted limited partner unit, compared to a net loss of $191.4 million, or $(1.51) per basic and diluted limited partner unit, for the 2020 Period. The increase in net income resulted from higher revenues, reduced operating expenses, lower depreciation and $157.0 million of non-cash impairment charges in the 2020 Period. Excluding the impact of impairment charges, Adjusted net income of $68.8 million for the 2021 Period compares to an Adjusted net loss of $34.4 million for the 2020 Period. Coal sales volumes for the 2021 Period increased 18.0% compared to the 2020 Period, driving total revenues higher by 12.4%. Ongoing cost control and efficiency initiatives at our mining operations, offset in part by expense increases resulting from higher coal sales volumes, contributed to lower operating expenses of $409.6 million for the 2021 Period, compared to $421.5 million for the 2020 Period. Adjusted EBITDA increased 45.3% to $212.9 million in the 2021 Period compared to $146.5 million in the 2020 Period. (For definitions of Adjusted net income (loss) and Adjusted EBITDA and related reconciliations to comparable GAAP financial measures, please see the end of this release.)

ARLP also announced today that the Board of Directors of its general partner declared a cash distribution to unitholders of $0.10 per unit (an annualized rate of $0.40 per unit) for the 2021 Quarter, payable on August 13, 2021 to all unitholders of record as of the close of trading on August 6, 2021. The announced distribution is equal to the distribution declared for the Sequential Quarter.

"ARLP’s performance during the 2021 Quarter was exceptional as we posted increases to key financial and operating metrics," said Joseph W. Craft III, Chairman, President and Chief Executive Officer. "Coal sales volumes increased 1.0 million tons as weather-impacted shipment delays in the Sequential Quarter were shipped during the 2021 Quarter and we significantly strengthened our contract book by securing new commitments to deliver approximately 5.0 million tons over the balance of this year and an additional 3.7 million tons for delivery in 2022 through 2024. Benefitting from significantly higher oil & gas prices and improved coal royalty volumes, our royalties segments also performed well during the 2021 Quarter ─ contributing $22.2 million of Segment Adjusted EBITDA."

Mr. Craft continued, "With the strong performance from all of our business segments, ARLP generated $79.4 million of free cash flow during the 2021 Quarter which was used to reduce total debt and finance lease obligations by $59.5 million and improve total leverage to 1.08 times." (For a definition of free cash flow and related reconciliation to the comparable GAAP financial measure, please see the end of this release.)

Operating Results and Analysis

ARLP's coal sales volumes increased in all regions compared to both the 2020 and Sequential Quarters. Improved coal demand and increased export shipments during the 2021 Quarter drove coal sales volumes higher by 61.9% and 31.9% in the Illinois Basin and Appalachian regions, respectively, compared to the 2020 Quarter, which was adversely impacted by the pandemic. Compared to the Sequential Quarter, Illinois Basin coal sales volumes increased 14.0% in the 2021 Quarter primarily as a result of increased sales volumes from the Warrior and River View mines reflecting in part weather-related shipment delays during the Sequential Quarter and increased export volumes in the 2021 Quarter. In Appalachia, coal sales volumes increased 17.1% compared to the Sequential Quarter due to increased sales volumes at our Tunnel Ridge mine primarily as a result of increased demand in the 2021 Quarter and an unplanned customer plant outage in the Sequential Quarter. Coal sales price per ton sold in the 2021 Quarter decreased in both regions compared to the 2020 Quarter reflecting the expiration of higher-priced sales contracts. In Appalachia, lower coal sales prices during the 2021 Quarter also reflect reduced export shipments of metallurgical coal from our Mettiki mine compared to both the 2020 and Sequential Quarters.

Total coal inventory fell to 1.4 million tons at the end of the 2021 Quarter, a decrease of 0.3 million tons compared to the end of the 2020 Quarter. This reduction resulted from higher coal sales volumes as discussed above, offset in part by a 73.1% increase in production volumes in the 2021 Quarter, reflecting the temporary idling of production at certain mines during the 2020 Quarter in response to weak market conditions resulting from the pandemic. Compared to the end of the Sequential Quarter, inventory decreased by 0.4 million tons due to increased sales and reduced production in the 2021 Quarter.

Compared to the 2020 Quarter, Segment Adjusted EBITDA Expense per ton in the Illinois Basin and Appalachia decreased by 22.7% and 23.9%, respectively, due to increased coal sales volumes, lower inventory charges, improved recoveries at several mines and the impact of ongoing expense control and efficiency initiatives at all of our mining operations. Compared to the Sequential Quarter, Segment Adjusted EBITDA Expense per ton in Appalachia decreased 13.7% primarily as a result of increased tons sold and reduced subsidence expense at our Tunnel Ridge mine as well as lower selling expenses per ton across the region during the 2021 Quarter.

For our Oil & Gas Royalties segment, significantly higher sales price realizations per BOE in the 2021 Quarter more than offset lower volumes leading Segment Adjusted EBITDA to increase by $8.5 million and $3.5 million compared to the 2020 and Sequential Quarters, respectively.

Segment Adjusted EBITDA for our Coal Royalties segment increased 80.5% to $6.8 million for the 2021 Quarter compared to $3.8 million for the 2020 Quarter as a result of increased royalty tons sold and higher average royalty rates per ton received from our mining subsidiaries, partially offset by increased selling expenses. Compared to the Sequential Quarter, Segment Adjusted EBITDA decreased slightly due to higher selling expenses and reduced average royalty rates, partially offset by increased royalty tons sold.

Outlook

"Commodity prices for each of our business segments have skyrocketed to levels not experienced in several years," said Mr. Craft. "Looking ahead, coal market fundamentals are extremely strong both domestically and internationally. In our primary U.S. markets, coal-fired generation has surged in response to a 7.5% year-over-year increase in power demand through the first half of 2021 and soaring natural gas prices. As utilities have leaned heavily on coal generation, stockpiles in our markets have been significantly drawn down and, with an elevated forward price curve for natural gas, coal demand is expected to be stable through 2022. International coal markets are also extremely positive. Driven by increased power demand as economies reopen around the world, elevated natural gas prices and a lack of global supply response, coal demand and prices have spiked. API-2 spot prices recently hit a 13-year high of $131 per metric ton, creating attractive market options for U.S. producers. We are hopeful we can benefit from these favorable market conditions. As a result, we are increasing the midpoint of our targeted total coal sales volumes for 2021 by approximately 6% to 32.9 million tons."

Mr. Craft continued, "Market fundamentals are also favorable for our royalty businesses. Oil, gas and natural gas liquids prices have increased and remain well above our previous expectations. Drilling and completion activity is also greater than previously anticipated, leading us to increase our 2021 full-year production volume expectations. In addition, increased sales volumes at ARLP’s coal mines are expected to benefit our coal royalties segment. With expectations of increased oil, gas and coal production and strong commodity pricing, we believe the contribution of our royalty segments to ARLP’s consolidated results will continue to grow."

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