Core Natural Resources, Inc.

What they do

Core produces and exports metallurgical and thermal coal from mining operations and terminal facilities across six states, owning 11 mines. West Virginia mines produce premium metallurgical coal for the global steel industry, surface mines in the Powder River Basin produce thermal coal for domestic and international markets, and thermal longwall mines produce high calorific value thermal coal. The company has ownership interests in two marine export terminals on the U.S. Eastern seaboard, transloading services at the Port of Baltimore, and access to third-party terminals on the West Coast and Gulf of America.

Revenue drivers

• High C.V. Thermal segment — Q2 2026 tons sold were 8.4 million at realized coal revenue of $58.11 per ton and cash cost of $38.58 per ton, producing a $19.53 per ton cash margin; the segment increased revenue by $6 million year over year.
• Metallurgical segment — Q2 2026 tons sold were 2.6 million (2.3 million coking coal and 0.3 million thermal byproduct) at $114.13 realized revenue per ton and $85.65 cash cost, producing a $28.48 per ton cash margin; the segment increased revenue by $66 million year over year.
• Powder River Basin segment — Q2 2026 tons sold were 10.2 million at $14.28 realized revenue per ton, below the $14.85 cash cost per ton, producing a negative $0.57 per ton cash margin.
• Core Marine Terminal segment — Includes transloading services at the Port of Baltimore and other revenue; this segment increased revenue by $4 million year over year in Q2 2026.

Recent performance

Second quarter 2026 net income was $126.5 million, or $2.51 per diluted share, with adjusted EBITDA of $323.6 million. Revenues were $1.1 billion, up $39 million from the prior-year quarter. Net cash provided by operating activities was $250 million and free cash flow was $148 million. The company settled the Leer South insurance claim for total recoveries of $154.5 million, with $125.4 million recorded in Q2 2026 and $135.1 million in the six months ended June 30, 2026. Core returned $68 million to stockholders in the quarter and $360 million since February 2025.

Strategy

The merger joined two operating platforms to create a premier North American coal producer and exporter, with expected synergies from support function optimization, enhanced marketing and an expanded logistics network. Management is focused on operational excellence, per-ton cost reductions and margin expansion across the combined mining platform. The marketing team secured 16 million tons of new sales commitments in Q2 2026 at prices expected to support advantageous margins. Core's capital return framework targets returning capital to stockholders while generating strong free cash flow.

Risks

• Mine operational disruption — A January 2025 combustion event at the Leer South mine caused the company to incur $101 million of fire extinguishment and idle costs in 2025 and required repositioning of longwall equipment before operations resumed in December 2025.
• Powder River Basin negative margin — The Powder River Basin segment reported a negative $0.57 per ton cash margin in Q2 2026, with cash costs exceeding realized coal revenue due to lower fixed cost absorption and higher fuel costs.
• Coal price and demand exposure — Realized coking coal revenue per ton declined slightly to $121.43 in Q2 2026 from $122.11 in Q1 2026, and metallurgical and thermal coal revenues are sensitive to global steel and energy market conditions.
• Merger integration and leverage — The January 2025 Arch merger created a combined company with $317.3 million of long-term debt at December 31, 2025 and total liabilities of $2.40 billion at June 30, 2026, requiring successful integration and synergy realization.

Outlook

Management expects the High C.V. thermal and metallurgical segments to continue improving per-ton costs and operating margins, and described the segments as shifting into high gear. For the Powder River Basin, Core expects a substantial improvement in sales volumes and unit costs in the second half of 2026. The company also expects its capital return program to accelerate as cash generation potential is realized.
