FINANCIAL RESULTS DURING Q2, CORE ACHIEVED A 17-PERCENT QUARTER-OVER-QUARTER INCREASE IN ADJUSTED EBITDA Adjusted EBITDA1 (in millions) High calorific value thermal segment continues to execute well, with a significant quarter-over-quarter step-up in sales volumes and a significant reduction in unit costs acting to counterbalance the impacts of a soft seaborne market environment With the exception of Leer South, where the longwall remained idle, the metallurgical segment turned in a solid operational performance – led by the Leer mine – against a still-weak metallurgical market environment The Powder River Basin segment again executed at a high level, with higher-than-anticipated sales volumes of 12.6 million tons reflecting the efforts of power generators to accelerate shipments in advance of the summer season Free Cash Flow1 (in millions) 1 Adjusted EBITDA and free cash flow are non-GAAP measures; see the Appendix for a reconciliation of these amounts to the most directly comparable GAAP measures.

COMMITTED VOLUMES 2025 CONTRACTED POSITION FOR CORE’S THREE MINING SEGMENTS High Calorific Value Thermal Segment (projected volumes and committed and priced position, in short tons and realized coal revenue per ton sold1) Metallurgical Segment (projected coking coal volumes and committed and priced position, in short tons and realized coal revenue per ton sold1) 26.0 (at $61 - $63) 29.8 (at $60 - $62) 29 – 31 29 – 31 Committed / Priced Committed / Unpriced Uncommitted 3.5 4.5 (at $118.20) 7.5 – 8.0 7.5 – 8.0 3.0 2.9 (at $122.38) 4.3 3.0 Powder River Basin Segment (projected volumes and committed and priced position, in short tons and realized coal revenue per ton sold1) 41.9 (at $14.77) 47.8 (at $14.40)2 39 – 42 45 – 48 The High Calorific Value Thermal segment has a committed book of ~13 million tons for delivery in 2026 The Powder River Basin segment has a committed book of ~33 million tons for delivery in 2026 1 Core is unable to provide a reconciliation of realized coal revenue per ton sold guidance, which is an operating ratio derived from non-GAAP financial measures, without unreasonable efforts due to the unknown effect, timing and potential significance of certain income statement items. 2 Now reflects the impact of the recently enacted royalty rate reduction on federal coal leases in the year’s second half, which is expected to result in lower realized coal revenue per ton sold as well as lower cash cost of coal sold per ton, but an improved sales margin overall

COST GUIDANCE 2025 CASH COST GUIDANCE FOR CORE’S THREE MINING SEGMENTS Core is targeting lower cash cost of coal sold per ton1 in its high calorific value thermal segment during the second half, consistent with the full-year guidance indicated above Core is guiding to higher-than-normal cash cost of coal sold per ton1 in its metallurgical segment in 2025 due to the longwall outage at Leer South, but expects a return to a more normalized range in the low $90s for 2026 Core has lowered its guidance for cash cost of coal sold per ton1 in the Powder River Basin segment for full year 2025, reflecting a strong first half performance and projected strong volumes in the year’s second half, as well as benefits expected from the recently enacted royalty rate reduction on federal coal leases Segment Projected Cash Cost of Coal Sold Per Ton1 High Calorific Value Thermal $38.00 – $40.00 Metallurgical $95.00 – $99.00 Powder River Basin $12.75 – $13.25 1 Core is unable to provide a reconciliation of cash cost of coal sold per ton guidance, which is an operating ratio derived from non-GAAP financial measures, without unreasonable efforts due to the unknown effect, timing and potential significance of certain income statement items.

COST EXECUTION CASH COST EXECUTION FOR CORE’S THREE MINING SEGMENTS Segment Q1 Q2 High Calorific Value Thermal $42.78 $39.47 Metallurgical $91.00 $95.93 Powder River Basin $12.44 $13.40 Core’s high calorific value thermal segment achieved an 8 percent quarter-over-quarter reduction in its cash cost of coal sold per ton1, due in part to three longwall moves at the PAMC in Q1 The metallurgical segment achieved a cash cost of coal sold per ton1 of $95.93 and incurred $21.2 million associated with combustion-related and idle costs at Leer South The Powder River Basin segment achieved another strong cash cost of coal sold per ton1 in Q2 due to higher-than-anticipated sales volumes, although costs were higher on a quarter-over-quarter basis in Q2 versus Q1 due to pit inventory monetization in Q1 1 Cash cost of coal sold per ton is an operating ratio derived from non-GAAP financial measures; see the Appendix for a reconciliation to the most directly comparable GAAP measure.

LEER SOUTH IS EXECUTING A PLAN TO RECOVER AND REPOSITION THE LONGWALL EQUIPMENT BY THE END OF OCTOBER In mid-January 2025, Core announced it was temporarily sealing Leer South’s active longwall panel to extinguish isolated combustion-related activity occurring in a mined-out area On June 10th, consistent with the previously provided timeline, Core personnel and regulatory officials re-entered the sealed area The operating team evaluated the major equipment and infrastructure, visually affirmed that it was in good condition, and repressurized the longwall shields On June 26th, after more than two weeks in the mine, the team found it necessary to again evacuate and reseal the affected area in the wake of an increase in carbon monoxide levels The Core team is currently working closely with federal and state officials on a plan to recover and reposition the longwall equipment by the end of October 2025, 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 Q3 2025

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 In addition, the Administration directed the Secretary of Energy to “accelerate the development, deployment, and reliability” 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 On July 4th, the President signed into law the “One Big Beautiful Bill Act,” which included provisions that stand to benefit Core Designation of metallurgical coal as a “critical material” under the Advanced Manufacturing Tax Credit (45X) Reduction in the royalty rate for federal coal leases Significant cuts to federal subsidies for renewable energy Other provisions that could prove beneficial over time, including language intended to facilitate investments in advanced power projects via Department of Energy loans as well as to facilitate an increase in the leasing of federal coal Core applauds the President and Congress for taking these historic steps to help ensure that coal remains a key element of America’s future energy supply as well as a stabilizing force in both domestic and international markets RECENT POLICY DEVELOPMENTS THAT SHOULD ENHANCE COAL’S COMPETITIVENESS AND OUTLOOK IN BOTH THE U.S. AND OVERSEAS

FORTIFYING THE BALANCE SHEET Equipment Leases During Q2 2025, Core increased cash and cash equivalents by $25 million and overall liquidity by $90 million At 6/30/25, Core had $948 million of total liquidity, including $413 million in cash and cash equivalents The significant majority of Core’s debt consists of unsecured, tax-exempt bonds with an initial 10-year term (as of Q1 2025) and a weighted-average interest rate of 5.3 percent Adding to its financial flexibility, Core has a $600 million revolving credit facility and – in July 2025 – consolidated its legacy accounts receivable securitization facilities into a single facility with a $250 million borrowing base and a maturity date in 2028 In its first six months as a combined company, Core has now successfully put in place its desired post-merger capital structure Core Has a Strong Balance Sheet and a Net Cash Positive Position ($ in mm) Net Cash1 = $21 Million A/R Securitization Facility Availability 1 Net cash is a non-GAAP measure; see the Appendix for a reconciliation of this non-GAAP measure to the most directly comparable GAAP measure.
