Advances previously detailed plan to resume longwall production at Leer South

CANONSBURG, Pa., Aug. 5, 2025 /PRNewswire/ -- Today, Core Natural Resources, Inc. (NYSE:CNR) ("Core" or the "company") reported a net loss of $36.6 million, or $0.70 per diluted share, in the second quarter of 2025. Core reported adjusted EBITDA¹ of $144.3 million for the second quarter of 2025, which included Leer South fire extinguishment and idle mine cash costs of $21.2 million. Revenues totaled $1,102.4 million in Q2.

"During the second quarter, the Core team continued to demonstrate the value-driving potential of the combined platform, executing at a high level at our flagship Pennsylvania Mining Complex (PAMC) and Leer longwall operations, continuing to unlock the value of the substantial synergies created by the merger, and generating significant free cash flow¹ despite a soft market environment and the longwall outage at Leer South," said Paul A. Lang, Core's chief executive officer. "In aggregate, those efforts facilitated the return to stockholders of $87.1 million in Q2 via our capital return program."

Operational Update

"During the second quarter, Core's high c.v. thermal coal segment continued to execute at a world-class level, with a significant step-up in sales volumes and lower unit costs acting to counterbalance modest erosion in average selling price in the face of a softer market environment," Lang said. "While the metallurgical segment's performance was again constrained by the longwall outage at Leer South, the rest of the platform executed well, led by the Leer mine, which set a production record for the second straight quarter. Supplementing our two core operating segments, the Powder River Basin segment also turned in a solid performance, with strengthening domestic power demand setting the stage for another strong adjusted EBITDA contribution."

During the second quarter of 2025, Core's high c.v. thermal coal segment achieved an 18-percent increase in sales volumes versus Q1 2025, when production was constrained by three longwall moves. The segment achieved realized coal revenue per ton sold¹ of $60.50, which was modestly lower than the Q1 realization due to lower pricing on spot sales as well as a lower energy market adjustment (EMA) on power-price-linked domestic tons. The segment had cash cost of coal sold per ton¹ of $39.47.

With the exception of Leer South, where longwall production has yet to resume, the metallurgical segment turned in a solid performance. Coking coal sales totaled 1.9 million tons, consistent with Q1 2025, and thermal byproduct sales totaled 0.3 million tons. The segment achieved realized coal revenue per ton sold¹ for coking coal of $114.71 and realized coal revenue per ton sold¹ for the metallurgical segment as a whole – inclusive of thermal byproduct sales – of $104.22. The metallurgical segment reported a cash cost of coal sold per ton¹ of $95.93 and incurred $21.2 million in costs associated with the extinguishment of combustion activity and idle mine costs at Leer South.

The Powder River Basin segment executed at a high level for the second straight quarter. Sales volumes totaled 12.6 million tons as power generators worked to accelerate shipments in advance of the summer season. Realized coal revenue per ton sold¹ was $14.69, while the cash cost of coal sold per ton¹ was $13.40, resulting in a cash margin per ton sold in excess of previously provided guidance levels.

Synergy Update

As indicated, Core has again increased its targeted range for annual synergy generation to between $150 million and $170 million per year, an approximately 30 percent aggregate increase at the midpoint when compared to the guidance furnished at the time of the merger's announcement.

"The Core team continues to drive forward with the capture of the originally identified synergies while surfacing new opportunities for value creation," Lang said. "As we look ahead, we expect these efforts to drive increases in the value we secure for our products in the marketplace, reductions in our average operating costs, an expansion of our operating margins, and a significantly leaner corporate structure."

Financial, Liquidity, and Capital Return Update

In February, Core announced a new capital return framework targeting the return to stockholders of around 75 percent of free cash flow, with the significant majority of that return directed to share repurchases complemented by a sustaining quarterly dividend of $0.10 per share.

During Q2 2025, Core generated net cash provided by operating activities of $220.2 million and free cash flow of $131.1 million. The company invested $81.9 million to repurchase 1.2 million shares, or roughly 2 percent of total shares outstanding as of the program's launch, at an average share price of $69.64. Year-to-date, Core has now invested a total of $183.2 million to repurchase 2.6 million shares, or roughly 5 percent of total shares outstanding as of the program's launch.

As of June 30, 2025, Core had $816.8 million of remaining authorization under its existing $1.0 billion share repurchase program.

In addition, and in keeping with the tenets of its capital return program, the board declared a $0.10 per share quarterly dividend payable on September 15, 2025, to stockholders of record on August 29, 2025.

"As we look ahead, we expect continuing robust free cash flow generation underpinned by anticipated strong performances from our high c.v. thermal and Powder River Basin segments," said Mitesh Thakkar, Core's president and chief financial officer. "That strong operating cash flow outlook – coupled with expected insurance recoveries, increased synergy capture, and the potential for further working capital improvement – gives us confidence in our ability to continue to return significant amounts of capital to our stockholders while maintaining a strong balance sheet."

At June 30, 2025, Core had total liquidity of $948 million, including $413 million in cash and cash equivalents.

In late July, Core consolidated the two legacy accounts receivable securitization facilities into a single facility with an extended term. The combined facility has a $250 million borrowing base; greater expected availability given the combined company's reduced customer and geographic concentration; and a maturity date in 2028. Moreover, the new facility – in combination with the recent $600 million revolving credit facility upsizing and $307 million tax-exempt bond refinancing – successfully completes Core's construction of its desired post-merger capital structure.

Leer South Update

In mid-January, Core announced that it was temporarily sealing Leer South's active longwall panel to extinguish isolated combustion-related activity occurring in a mined-out area. On June 10, 2025, consistent with the previously provided timeline, Core personnel and regulatory officials re-entered the sealed area of the mine and conducted an extensive evaluation of the major equipment and infrastructure. As expected, the operating team found that the longwall had been largely unaffected by the combustion event and that the major components and systems were in good condition.

On June 26, 2025, after more than two weeks in the mine, the team found it necessary to again evacuate the mine and reseal the affected area in the wake of an increase in carbon monoxide levels. The Core team is working closely with federal and state officials on a plan to recover and reposition the longwall equipment by the end of October, with the objective of resuming longwall production shortly thereafter.

Core currently expects to incur fire extinguishment and idle costs of $20 million to $30 million at Leer South in the third quarter of 2025. Core expects insurance recoveries associated with developments at Leer South to exceed $100 million.

Marketing Update

Core continues to capitalize on its strong book of committed thermal business and a gradual recovery in domestic thermal coal demand while navigating softer market conditions in the international arena.

In the high c.v. thermal segment, Core has now locked in commitments totaling 30.0 million tons for delivery in 2025 – and thus is nearly fully committed – at a projected realized coal revenue per ton sold² of $60 to $62 per ton. That translates into an average operating margin of $22 per ton based on the mid-point of guidance for both realized coal revenue per ton sold and cash cost of coal sold per ton². In addition, the segment has a committed book of around 13 million tons for delivery in 2026.

In the metallurgical segment, Core has commitments in place for virtually all its projected coking coal sales volumes for delivery in 2025, with the majority of yet-to-be-shipped tons tied to market-based pricing mechanisms.

In its Powder River Basin segment, Core is fully committed for 2025 at a projected realized coal revenue per ton sold² of $14.40 and has around 33 million tons committed for delivery in 2026.

Policy Developments

In April 2025, President Trump issued a series of executive orders intended to reduce the regulatory burden on America's coal-based power plants and to ensure the long-term preservation of the U.S. coal fleet. The Trump Administration views the coal fleet as essential to the security, resilience, and reliability of America's power system.

In addition, the Administration directed the Secretary of Energy to take actions – via funding and other support mechanisms – to "accelerate the development, deployment, and commercialization" of coal-based technologies in areas such as building products, batteries, and other advanced carbon materials, as well as power generation. Core expects these efforts to facilitate additional opportunities for its Innovations business unit, which is already driving forward on all these fronts.

Then, on July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (OBBBA), which included provisions designed to strengthen the U.S. coal industry and enhance the competitiveness of American coal overseas. The legislation contains language designating U.S.-produced metallurgical coal as a "critical material" under Section 45X, through which the company will be eligible for a 2.5-percent monetizable tax credit on production-related costs for four years beginning in 2026. In addition, OBBBA lowers the royalty rate on tons produced on federal lands, which stands to enhance the competitiveness of Core's Powder River Basin and West Elk mines.

Even more recently, the Trump Administration has announced plans to pursue still further legal and administrative efforts – via the U.S. Environmental Protection Agency and other governmental entities – to facilitate the continued operation of the U.S. coal-based power generation fleet well into the future in support of grid reliability and electricity affordability.

"In recent months, President Trump and the U.S. Congress have taken historic steps to ensure that U.S. coal remains a cornerstone of America's future energy supply and a stabilizing force in global energy markets," Lang said. "The President's recognition and inclusion of a number of our hourly employees in a White House ceremony for the signing of several executive orders underscored the past, present and future contributions of America's coal miners in meeting this country's energy and industrial needs – a recognition sorely missing in recent years."

Outlook

"In our first six months as a combined company, the Core team has made great progress in integrating the combined operating, marketing and logistics portfolio into a cohesive, high-performing unit while unlocking the synergistic value created by the merger," Lang said. "With our world-class mines, highly strategic logistical network, strong balance sheet, significant cash-generating capabilities, and talented workforce, we believe we are uniquely equipped to create stockholder value in a wide range of market environments. The team remains highly focused on capitalizing on our many strengths – and in doing so facilitating solid returns via our capital return program in today's soft market environment, while positioning the portfolio to drive still greater value as coal markets recover."

Free cash flow is a non-GAAP financial measure, defined as net cash provided by operating activities plus proceeds from sales of assets and unrestricted cash proceeds from the Merger with Arch Resources, Inc., less capital expenditures and investments in mining-related activities. Management believes that this measure is meaningful to investors because management reviews cash flows generated from operations and non-core asset sales after taking into consideration capital expenditures due to the fact that these expenditures are considered necessary to maintain and expand the company's asset base and are expected to generate future cash flows from operations. It is important to note that free cash flow does not represent the residual cash flow available for discretionary expenditures, since other non-discretionary expenditures, such as mandatory debt service requirements, are not deducted from the measure. The following table presents a reconciliation of free cash flow to net cash provided by operating activities, the most directly comparable GAAP financial measure, on a historical basis, for the three months ended June 30, 2025 (in thousands).
