CNR

Business Context and Reporting Period

Company: Core Natural Resources, Inc. (formerly CONSOL Energy Inc.)
Reporting Period: Fiscal Year Ended December 31, 2025
Key Event: On January 14, 2025, the Company completed an all-stock merger of equals with Arch Resources, Inc. The combined entity operates four reportable segments: High CV Thermal, Metallurgical, Powder River Basin (PRB), and Core Marine Terminal. The Company is a large accelerated filer trading on the NYSE under the ticker "CNR."

Key Financial Metrics

Note: 2024 figures are recast to reflect the new segment structure. The Net Loss in 2025 was driven by significant non-recurring merger costs, idle mine costs, and pension litigation expenses.

Material Changes vs. Prior Period

• Revenue Growth: Consolidated revenues increased by approximately $2.0 billion, primarily due to the inclusion of legacy Arch operations (Metallurgical and PRB segments) which contributed $2.048 billion in revenue.
• Profitability Decline: Despite revenue growth, the Company reported a Net Loss of $153 million compared to Net Income of $286 million in 2024. This was largely due to $66 million in non-recurring merger transaction costs, $101 million in fire extinguishment and idle costs at the Leer South mine, and a $68 million charge related to 1974 UMWA Pension Plan litigation.
• Production Volume: Total coal production surged to 87.8 million tons from 26.1 million tons, driven by the acquisition of Arch's Black Thunder and Coal Creek mines (PRB) and metallurgical assets.
• Debt Structure: Long-term debt increased to $459 million following the issuance of $307 million in Series 2025 tax-exempt bonds to refinance legacy debt and fund capital projects.

Guidance, Outlook, and Risks

Management Commentary:

• Strategic Focus: The Company aims to leverage low-cost assets to access export markets while maintaining revenue visibility through domestic power plant contracts. It is evaluating opportunities in critical minerals (rare earth elements) and advanced materials via CONSOL Innovations.
• Operational Challenges: The Leer South mine experienced a combustion-related incident in January 2025, resulting in $101 million in costs (partially offset by $19.4 million in insurance advances). Longwall operations resumed in December 2025. The West Elk mine incurred transition costs in Q4 2025.
• Capital Return: The Board approved a $1 billion share repurchase program and a quarterly dividend of $0.10 per share.

Risks and Contingencies:

• Legal: Ongoing litigation with the UMWA 1992 Benefit Plan regarding retiree medical liabilities, with the plaintiff seeking approximately $90 million plus fees.
• Regulatory: Exposure to changing environmental regulations, including potential rollbacks or new mandates on greenhouse gas emissions and mine safety (e.g., Black Lung self-insurance security requirements).
• Market: Volatility in coal prices, particularly in metallurgical and export thermal markets, and reliance on major customers (India accounted for >10% of revenue in 2025).

Investor Verification Checklist

• Merger Integration: Verify the realization of anticipated synergies and cost savings from the Arch merger, specifically regarding the integration of IT systems and logistics.
• Leer South Mine Status: Confirm the long-term stability of the Leer South mine following the combustion incident and the adequacy of insurance recoveries for the $101 million in costs.
• UMWA Litigation: Monitor the status of the 1992 Benefit Plan lawsuit and the potential impact of the $90 million+ claim on future cash flows.
• Debt Covenants: Review compliance with the Revolving Credit Facility covenants (max 1.50x first lien leverage, 2.50x total net leverage) given the increased debt load.
• Regulatory Environment: Assess the impact of the "One Big Beautiful Bill Act" (OBBBA) and executive orders on domestic thermal coal demand and tax credits.
