( NYSE : CNR ) ( " Core " or the " company " ) reported net income of $ 126.5 million , or $ 2.51 per diluted share , in the second quarter of 2026. Additionally , Core reported adjusted EBITDA¹ of $ 323.6 million in the quarter . During Q2 , Core settled the Leer South insurance claim for the full limit recovery and recognized the remaining $ 125.4 million of proceeds . Second quarter revenues totaled $ 1.1 billion . " During Q2 , the Core team made excellent progress in driving operational excellence across the combined mining platform while generating strong free cash flow and robust capital returns , " said Jimmy Brock , Core's chairman and CEO . " With our marquee operating segments now shifting into high gear , we expect to showcase Core's full , cash - generating potential moving forward , thus powering a further acceleration of our already substantial capital return program . " Operational and Marketing Update During the second quarter of 2026 , Core's high calorific value thermal segment had coal sales of 8.4 million tons , representing a 9 percent quarter - over - quarter increase , and achieved realized coal revenue per ton sold 1 of $ 58.11 . The segment had cash cost of coal sold per ton of $ 38.58 , representing a 9 percent quarter - over - quarter improvement . In Core's metallurgical segment during Q2 , coking coal sales totaled 2.3 million tons , representing an 8 percent quarter - over- quarter improvement , and thermal byproduct sales totaled 0.3 million tons . The segment achieved realized coal revenue per ton sold for coking coal of $ 121.43 , representing a slight decline versus Q1 2026. Realized coal revenue per ton sold for the metallurgical segment as a whole was $ 114.13 . The metallurgical segment reported a cash cost of coal sold per ton¹ of $ 85.65 , representing a 7 percent improvement from the previous quarter . In the Powder River Basin segment , Q2 sales volumes totaled 10.2 million tons , reflecting seasonally depressed spring shipment levels . Realized coal revenue per ton sold¹ was $ 14.28 , which was generally in line with Q1 2026 , and cash cost of coal sold per ton¹ came in at $ 14.85 , representing a 9 percent increase due to lower fixed cost absorption stemming from the lower shipment levels as well as increased fuel costs . Core expects a substantial improvement in the segment's sales volumes and unit costs in the year's back half . During Q2 , the marketing team secured 16 million tons of new sales commitments across all segments for delivery in future periods , at prices expected to support advantageous margins .

During Q2 2026, the company invested $63.0 million to repurchase 719,904 shares of its common stock at an average share price of $87.54. Core has now invested a total of $329.2 million to repurchase 4.3 million shares of common stock, or roughly 7.9 percent of total shares outstanding as of the program's launch, at an average share price of $77.04, and a total of $360.1 million, inclusive of dividend payments, in the capital return program overall. Since the inception of its capital return program in February 2025, Core has returned approximately 80 percent of its free cash flow 1 to stockholders via its capital return program. As of June 30, 2026, Core had $670.8 million of remaining authorization under its existing $1.0 billion share repurchase program. In addition, the board declared a $0.10 per share quarterly dividend payable on September 18, 2026, to stockholders of record on August 31, 2026. "During Q2, Core continued to perform at world-class levels and once again demonstrated the value of its diversified, strategic, world-class mining portfolio by generating substantial levels of free cash flow and funding robust capital returns despite a relatively soft market environment," said Mitesh Thakkar, Core's president and chief financial officer. "Given Core's step-change in operational execution, strong cash balance, incremental cash proceeds from insurance settlements, projected drawdown of coal inventories, and an improving shipping outlook in the Powder River Basin, we believe the stage is set for even stronger capital returns — and an accelerated reduction in share count — in the year's second half." As part of the full limit recovery of its Leer South insurance claim, which netted a total of $154.5 million across all periods, Core collected $88.1 million of insurance proceeds in Q2 and the remaining $37.9 million in July. At June 30, 2026, Core had total liquidity of $1.0 billion, including $474.0 million in cash and cash equivalents and short-term investments. Market Update While U.S. thermal coal demand was pressured by moderate temperatures, low natural gas prices, and inflated customer stockpiles during Q2, Core expects improving market dynamics in the year's second half and views the longer term outlook as promising. U.S. grid operators project substantial power demand growth through the remainder of the decade, spurred by reindustrialization and the AI-driven data center build-out. With the U.S. coal fleet operating at an average capacity factor of less than 50 percent – and with the Trump Administration moving aggressively to ensure the long-term viability of the U.S. coal fleet – Core expects U.S. thermal coal demand to climb. The outlook for seaborne industrial coal demand appears positive as well. India's cement demand is climbing at a significant pace, propelled by that country's infrastructure build-out, and the International Energy Agency expects global electricity demand to grow at 3.6 percent per year through the remainder of the decade. Seaborne metallurgical markets remain muted in the face of two years of contraction in global hot metal output, and coking coal price assessments on the U.S. East Coast continue to lag Australian price indices by a historically wide margin. Core expects U.S. East Coast prices to recover over time as global hot metal demand rebounds and as Asian buyers seek to take advantage of the wide price spread. Meanwhile, Core continues to make good progress in marketing its Leer brand coal as an advantageous and high value-in-use substitute for Australian premium low-vol coals. Core expects the ongoing, steel-dependent build-out of Southeast Asian economies – along with sustained investment in new blast furnace capacity across that region – to support a constructive, long-term market outlook for high-quality coking coals. Outlook "Looking ahead, we remain laser-focused on achieving world-class productivity and industry-leading cost performance across our entire mining portfolio while operating in tight alignment with our core values of safety and compliance, continuous improvement, and financial performance," Brock said. "Our goal is to drive strong and improving capital returns in the current soft market environment while laying the foundation for truly exceptional returns as coal markets rebound. We see compelling, long-term market opportunities ahead — including resurgent U.S. power demand, tightening global energy markets, and an ongoing

infrastructure build-out in the developing world — and we are preparing Core to capitalize on all fronts." 1 - Adjusted EBITDA and Free Cash Flow are non-GAAP financial measures and Realized Coal Revenue per Ton Sold and Cash Cost of Coal Sold per Ton are operating ratios derived from non-GAAP financial measures, each of which is reconciled to the most directly comparable GAAP financial measures below, under the caption "Reconciliation of Non-GAAP Financial Measures." Cash Margin per Ton Sold is an operating ratio derived from non-GAAP financial measures and is defined as realized coal revenue per ton sold less cash cost of coal sold per ton. 2026 Guidance 2026 Tons $ per ton Sales Volume (in millions of tons) Coking 1 8.8 - 9.4 High C.V.

Adjusted EBITDA $ 164,605 $ 199,666 $ (5,797) $ 17,770 $ (52,618) $ 323,626 Free cash flow is a non-GAAP financial measure, defined as net cash provided by 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.
