Core Natural Resources Reports First Quarter 2025 Results
Returns $106.6 million to investors via share buybacks and quarterly dividend
Increases merger-related synergies target by 10% at midpoint to between $125 and $150 million
Makes excellent progress towards full resumption of operations at Leer South
Executes well-timed capital market transactions establishing target capital structure while boosting liquidity,
extending maturities, reducing interest rates, and increasing financial flexibility
CANONSBURG, PA (May 8, 2025) - Today, Core Natural Resources, Inc. (NYSE: CNR) (“Core” or the “company”) reported a net loss of $69.3 million, or $1.38 per diluted share, in the first quarter of 2025, which included merger-related expenses of $49.2 million and a loss of $11.7 million associated with the extinguishment of debt. Core reported adjusted EBITDA^1^ of $123.5 million and revenues of $1,017.4 million for the first quarter of 2025.
“Since completing the merger on January 14, Core has made exceptional progress in integrating the operating portfolio and beginning to unlock the tremendous potential of the new company,” said Paul A. Lang, Core’s chief executive officer. “To date, the Core team has launched and executed upon a powerful capital return program; put in place strategies expected to deliver the previously identified synergies while increasing the targeted range by 10 percent; and further tightened the alignment between its two core lines of business – global metallurgical and high calorific value thermal coals.”
“Importantly, the Core team is already executing at a high level operationally, driven by a strong performance by the high c.v. thermal segment,” Lang said. “Even with the uncertain global trade environment, the high c.v. thermal segment leveraged its strong book of contracted business, strengthening U.S. power markets, and solid pricing in the international marketplace to generate substantial free cash flow^1^. Meanwhile, the metallurgical segment performed as expected, with a solid cost performance across most of the operating portfolio – led by record quarterly production at the Leer mine – serving to limit the impact of the longwall outage at Leer South.”
As indicated, Core also made excellent progress on its recently adopted capital return program, returning a total of $101.3 million to stockholders via the repurchase of 1.4 million shares, or around 3 percent of Core’s total shares outstanding as of the program’s launch on February 20, 2025. The company also paid a quarterly dividend of $0.10 per share. “At a time when most of the global resource sector is focused on cash preservation, our low-cost mining operations, advantageous contract position, substantial cash balance, and strong balance sheet are enabling Core to act opportunistically in today’s depressed equity market environment,” Lang said.
Leer South Update
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, the Leer South team – in close collaboration with federal and state regulators – has safely sealed the affected area, extinguished all combustion-related activity, resumed development work with continuous miner units, and completed a remote assessment of the mine’s longwall system, which solidified the company’s belief that the longwall equipment was largely unaffected by the event.
“On behalf of the board and the entire senior management team, I want to again commend the operations team as well as federal and state regulators for their exceptional, ongoing work in managing this situation in a safe and efficient manner,” Lang said. “We continue to make substantial progress on all fronts and remain on track to resume longwall production by mid-year, in keeping with our originally indicated timeline. Notably, development work at the mine – which resumed in February with the restart of continuous miner units – is progressing at a strong pace and acting to greatly increase the development lead time for future longwall production. We expect that increase to translate into higher longwall productivity once longwall operations resume.”
Synergy Update
As indicated, Core has increased its targeted range for synergy creation by 10 percent at the midpoint to $125 to $150 million per year, having already executed strategies expected to deliver the midpoint of the initially provided guidance. Moreover, the team continues to press forward with its intensive efforts to identify and pursue further opportunities.
“In the first four months since the merger’s completion, the Core team has made tremendous progress in integrating the operating portfolio and unlocking the value of the already identified synergies, while setting its sights on additional value creation via further streamlining, cost reduction, efficiency improvement, and product optimization efforts,” Lang said. “On top of the announced increase in our targeted range, we expect additional uplift in the synergy arena as coal markets normalize, which is expected to act to further increase incremental value in areas such as marketing and product blending.”
Operational Update
During the first quarter of 2025, Core’s high c.v. thermal coal segment had sales volumes of 7.1 million tons despite the fact that three of the PAMC’s five scheduled longwall moves for 2025 occurred in Q1 2025. Moreover, it achieved realized coal revenue per ton sold^1^ of $63.18, benefiting from a strong existing contracted position, solid pricing on incremental tons, and a substantial energy market adjustment on its power price linked domestic tons stemming from high PJM West power prices related to colder-than-normal winter weather. The segment had a cash cost of coal sold per ton^1^ of $42.78, which was higher than ratable due to the three longwall moves at the PAMC.
The metallurgical segment turned in a solid performance in Q1 in light of the longwall outage at Leer South, with total Q1 sales volumes of 2.3 million tons. The segment had coking coal sales of 1.9 million tons and thermal byproduct sales of 0.4 million tons, achieving realized coal revenue per ton sold^1^ for coking coal of $113.70 and realized coal revenue per ton sold^1^ for the metallurgical segment as a whole – inclusive of thermal byproduct sales – of $98.26. The metallurgical segment reported a cash cost of coal sold per ton^1^ of $91.00, which excluded costs associated with extinguishing the combustion and with the 30-day period during which the Leer South mine was idled entirely.
As indicated, the Leer South longwall was idle during the first quarter of 2025 due to the previously announced combustion-related event, but the mine remains on track to resume longwall operations mid-year. This should act to boost the segment’s sales volumes and lower its unit costs markedly in the second half of 2025. Core is guiding to a cash cost of coal sold per ton^2^ for the metallurgical segment in the low $90 range during the year’s second half.
Financial and Liquidity Update
At March 31, 2025, Core had total liquidity of $858.3 million, including $388.5 million in cash and cash equivalents.
In February 2025, Core announced a new capital return framework targeting the return to stockholders of around 75 percent of free cash flow^1^, with the significant majority of that return directed to share repurchases complemented by a sustaining quarterly dividend of $0.10 per share. Core moved quickly to act upon the program, investing $101.3 million to repurchase 1.4 million shares, or roughly 3 percent of total shares outstanding as of the program’s launch, at an average price of $73.52 per share.
In addition, and in keeping with the recently announced structure of its capital return program, Core’s board of directors has declared a $0.10 per share quarterly dividend payable on June 13, 2025, to stockholders of record on May 30, 2025.
“During the quarter, we executed on several capital market transactions that not only helped establish our target capital structure but also bolstered our liquidity, extended maturities, and added significant financial flexibility to execute our capital return program,” said Mitesh Thakkar, Core’s president and chief financial officer. “While the commodity markets are volatile, we are in an excellent position to opportunistically deploy our significant cash balances towards the capital return program given our expectations of strong free cash flow^1^ generation from our contracted book of business and low-cost asset base.”
As of March 31, 2025, Core had $898.7 million of remaining authorization under its existing $1.0 billion share repurchase program.
As previously announced, in connection with the closing of the merger, Core extended its revolving credit facility, upsizing the facility commitments to $600 million, extending the maturity, reducing the annual interest rate by 75 basis points, and further enhancing financial flexibility. Then, at the end of March 2025, Core announced that it had refinanced the tax-exempt bonds previously held by the legacy companies. As part of this refinancing effort, Core increased the total bond amount by more than 10 percent to $306.8 million; established an initial 10-year term for the now unsecured bonds; improved flexibility relative to the prior bonds; and reduced the weighted average interest rate to 5.3 percent.
“These successful refinancing efforts serve to underscore the strength of Core’s operating portfolio; the value of its greatly enhanced diversification and scale; and the power of its substantial cash-generating capabilities across a wide range of market environments,” Thakkar said. “With the refinancing of the tax-exempt bonds, which represent the vast majority of Core’s debt, we believe we have built a smart and strategic capital structure that furnishes tremendous financial flexibility while supporting the company’s long-term growth prospects.”
Market Dynamics
Core’s two principal lines of business – metallurgical coal and high calorific value thermal coal – continue to navigate softer market conditions in the international arena, where trade-related uncertainties continue to weigh on markets.
In the high calorific value thermal segment, Core’s substantial contracted position – at relatively advantageous pricing – is acting to counterbalance current export market softness, as is continued stability in key industrial market segments and strong domestic demand. At present, the high c.v. thermal segment has a committed and priced position – inclusive of select collared volumes – of approximately 26 million tons at a projected price of between $61 and $63 per ton for the year. Meanwhile, the domestic thermal market in the PAMC’s core market area has improved markedly in the wake of colder-than-normal temperatures in January and February.
Despite currently weak pricing levels, long-term market dynamics for Core’s metallurgical segment remain highly promising. New blast furnace capacity continues to come online across Southeast Asia, and Indian imports of seaborne coking coal continue to march higher, climbing an estimated 3 percent in 2024. In another positive trend for the overall global marketplace, Chinese imports of seaborne coking coal increased by around 20 million tons in 2024, a trend that is acting to counterbalance higher Chinese steel exports. On the supply side, aggregate production in the primary supply countries for high-quality seaborne coking coal – Australia, the United States, and Canada – remains under pressure, and current pricing levels appear to be inducing supply rationalization among high-cost producers, which should act to support a healthier supply-demand balance over time.
Outlook
“The Core team is off to an excellent start in integrating the combined operating, marketing and logistics portfolio into a cohesive, high-performing unit; capturing the substantial – and growing – synergies created by this transformational merger; and laying the foundation for long-term value creation via the tight alignment of its global metallurgical and high calorific value thermal segments,” Lang said. “We believe we are building a company that is uniquely equipped to capitalize on compelling global coal market dynamics – with our world-class mines, highly strategic logistical network, strong balance sheet, tremendous cash-generating capabilities, and – most importantly – exceptionally talented workforce that embraces our core values of safety, compliance, and continuous improvement. As we look ahead, we expect to continue to generate substantial levels of free cash flow^1^ – particularly in the year’s second half – and to continue to return significant amounts of cash to stockholders via our compelling capital return program.”
As detailed in the 2025 Guidance table below, Core either affirmed or enhanced its full-year guidance in all instances.
1 - Adjusted EBITDA and Free Cash Flow are non-GAAP financial measures and Realized Coal Revenue per Ton Sold andCash Cost of Coal Sold per Ton are operating ratios derived from non-GAAP financial measures, each of which are reconciled to the most directly comparable GAAP financial measures below, under the caption“Reconciliation of Non-GAAP Financial Measures”.
2 - Core is unable to provide a reconciliationof Metallurgical Cash Cost of Coal Sold per Ton, which is an operating ratio derived from non-GAAP financial measures, without unreasonable efforts due to the unknown effect, timing and potential significanceof certain income statement items.

Free cash flow is a non-GAAP financial measure, defined as net cash provided by (used in) 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 used in operating activities, the most directly comparable GAAP financial measure, on a historical basis, for the three months ended March 31, 2025 (in thousands).

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

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

| ^○^ | We define adjusted EBITDA as (i) net income (loss) plus income taxes, net interest expense and depreciation,<br>depletion and amortization, as adjusted for (ii) certain non-cash items, such as stock-based compensation and loss on debt extinguishment and (iii) certain<br>one-time transactions, such as merger-related expenses and certain litigation expenses for specific proceedings that arise outside of the ordinary course of our business. The GAAP measure most directly<br>comparable to adjusted EBITDA is net income (loss). | ||||||||||||||||||||

| ^○^ | Free cash flow is a non-GAAP financial measure, defined as net cash<br>provided by (used in) 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. The GAAP measure most<br>directly comparable to free cash flow is net cash provided by (used in) operating activities. | ||||||||||||||||||||
