First Quarter 2025 Highlights

Q1 2025 EXECUTIVE SUMMARY Since completing the merger on January 14, Core has made exceptional progress in integrating its operating portfolio and beginning to unlock the tremendous potential of the new company. – Paul Lang, CEO Reports a net loss of $69.3 million, or $1.38 per diluted share, in Q1, which included merger-related expenses of $49.2 million and a loss of $11.7 million associated with the extinguishment of debt Reports adjusted EBITDA1 of $123.5 million Highlights include: Return of $106.6 million to investors via share buybacks and quarterly dividend Increase of merger-related synergies target by 10% at midpoint, to between $125 and $150 million Excellent progress towards full resumption of operations at Leer South Execution of well-timed capital market transactions establishing target capital structure while boosting liquidity, extending maturities, reducing interest rates, and increasing financial flexibility 1 Adjusted EBITDA is a non-GAAP financial measure

CAPITAL RETURN PROGRAM DURING Q1, CORE RETURNED $106.6 MILLION TO STOCKHOLDERS UNDER ITS RECENTLY LAUNCHED CAPITAL RETURN PROGRAM As part of the effort, Core bought back around 1.4 million shares of stock, or nearly 3% of shares outstanding Reduction In Shares Outstanding Since February 20, 2025 (in millions of shares outstanding) Capital Returned During Q1, By Method (share buybacks versus dividend payments, in millions) (2.5)%

CORE IS STRONGER TOGETHER, BOOSTING ITS SYNERGY TARGET BY 10% AT MIDPOINT TO $125 TO $150 MILLION ANNUALLY Expected cost savings and operating synergies to be realized within 6 to 18 months following the close and then annually – with the expectation of additional synergy identification and capture thereafter LOGISTICS BEST PRACTICES PROCUREMENT Vendor purchase optimization Efficiencies from sharing of best practices, technology, and deep technical expertise SG&A Optimization of SG&A functions, streamlining across the company, and elimination of duplicative public company costs Optimization of capacity at port assets LOGISTICS & COAL BLENDING Product blending and related opportunities

LEER SOUTH REMAINS ON TRACK FOR A FULL RESUMPTION OF LONGWALL OPERATIONS BY MID-YEAR In mid-January 2025, Core announced that it was temporarily sealing Leer South’s active longwall panel to extinguish isolated combustion-related activity Since that time, Leer South has: Safely sealed the affected area Extinguished all combustion-related activity Resumed development work with continuous miner units Completed a remote assessment of the longwall system that affirmed the company’s belief that the longwall equipment was largely unaffected by the event Core remains on track to resume longwall production by mid-year Recent development work is progressing at a strong pace and has acted to greatly increase the development lead time for future longwall production, which should translate into higher productivity levels once longwall operations resume

CLEAR STRATEGY TO DRIVE GROWTH AND CREATE STOCKHOLDER VALUE

Core is strategically positioned to serve two constructive and growing segments of the global coal market

METALLURGICAL SEGMENT GLOBAL SEABORNE DEMAND FOR METALLURGICAL COAL IS EXPECTED TO GROW STEADILY AND CONSISTENTLY THROUGH MID-CENTURY Global seaborne coking coal demand is expected to continue to climb through 2050, buoyed by continued economic development and urbanization in India and the rest of Southeast Asia Approximately 60% of the world’s population lives in Asia, where metallurgical coal demand is centered and where indigenous sources of metallurgical coal are limited Based on the consensus estimate, demand – in aggregate – is expected to total more than 11 billion tons between now and 2050, which will significantly strain supply availability Projected Global Seaborne Metallurgical Imports, Through 2050 (in millions of metric tons) Source: Wood Mackenzie, AME, Internal

METALLURGICAL SEGMENT PROJECTED STEEL CAPACITY GROWTH IN SOUTHEAST ASIA IS PROJECTED TO BE SIGNIFICANT AND LARGELY BLAST FURNACE DRIVEN Wood Mackenzie estimates that Southeast Asia’s steel production will grow by more than 55% from 2024 to 2030 – from 59 million tons to 93 million tons – mostly via the blast furnace route Planned Blast Furnace Capacity Additions In India (in millions of metric tons) Planned Steel Capacity Additions, By Technology (in millions of metric tons) 2030 2024 CAPACITY ADDITIONS IN MT BLAST FURNACE SHARE OF NEW Southeast Asia 64 92% Myanmar 4 100% Thailand 2 0% Vietnam 14 85% Cambodia 4 100% Philippines 9 94% Malaysia 10 97% Indonesia 21 100% Source: Public Information, Company Filings, Internal, Wood Mackenzie, World Steel Association

METALLURGICAL SEGMENT LONG-RUN METALLURGICAL COAL PRICING HAS SHIFTED HIGHER The average long-run coking coal price continues to shift higher in the face of limited new investment, ESG pressures, and supportive long-term demand The coking coal benchmark has averaged $243 per metric ton on an inflation-adjusted basis since 2005 Core expects volatility to continue, but potentially with an upward bias as mining costs increase over time due to ongoing under-investment coupled with reserve degradation and depletion and policy measures Source: Bloomberg, Public Information, BLS, Internal Note: 2024 real dollars Annual Average Hard Coking Coal Price (US$ per metric ton, inflation adjusted)

HIGH C.V. THERMAL SEGMENT SEABORNE THERMAL COAL DEMAND HIT ANOTHER ALL-TIME HIGH IN 2024 Seaborne thermal coal demand has risen significantly since 2000 While global thermal coal consumption is likely to peak at some point, we don’t expect that peak to come anytime soon Even when that peak is reached, the decline is likely to be gradual – and extend over many years – when it comes The build-out of new coal-based generating capacity in Asia is continuing at a substantial pace Seaborne Thermal Coal Demand (in millions of metric tons) Source: Wood Mackenzie

HIGH C.V. THERMAL SEGMENT GLOBAL CEMENT PRODUCTION IN THE WORLD EXCLUDING CHINA IS PROJECTED TO CLIMB MARKEDLY THROUGH 2050 Global Cement Production (in millions of metric tons) Source: Wood Mackenzie, Internal The vast majority of the world’s cement production relies on coal as a feedstock – with each ton of cement requiring an estimated ~0.2 tons of coal on average

Thermal Segment Sells An Increasing Percentage Of Its Output Into Fast-Growing International Markets (based on actual 2024 shipments by legacy entities, in millions of short tons) While Core has the strategic flexibility to direct volumes into the most profitable market segment – whether in the international or domestic arena – the percentage of tons moving into the seaborne market is projected to continue to climb Core’s high calorific value thermal coals rank among the top 2% of all thermal coals sold into the 1.1-billion-metric-ton seaborne market on a heat content basis Core sells nearly 50% of its high calorific value thermal coal into industrial markets – including cement, brick, and crossover metallurgical applications – that are critical for global infrastructure development Industrial Ultra High C.V.
