Recent Developments
Dominion Terminal
We have a 35% ownership interest in DTA, which operates the Dominion Terminal, a coal export terminal in Newport News, Virginia. Through our storage capacity at DTA, we fulfill a broad range of coal quality requirements for our customers. In June 2026, the majority partner announced a key piece of equipment, a stacker reclaimer machine, at DTA sustained significant damage due to high winds from a storm. DTA leadership, as part of DTA's insurance claims process, is in contact with its insurance providers to evaluate its options and work on developing an action plan. The terminal remains operational, but the damage to the stacker reclaimer has resulted in a slowdown in handling coal from certain areas of the stockpile yard until equipment replacement or repairs or other workarounds can be put in place. As of September 30, 2026, this event has not had a material impact; however, further disruptions or delays could affect our operations, financial results or liquidity.
Merger
On January 14, 2025, the Company completed the Merger with Arch. Pursuant to the terms of the Merger Agreement, Merger Sub merged with and into Arch, with Arch continuing as the surviving corporation and as a wholly-owned subsidiary of the Company. See Note 2-Merger with Arch in the Notes to the Condensed Consolidated Financial Statements in this Report for additional information.
Combustion-Related Activity at Leer South Mine
On January 13, 2025, a combustion-related activity was reported at the Leer South mine, located in Barbour County, West Virginia. The Company temporarily sealed the Leer South mine's active longwall panel in order to extinguish such activity. The Company resumed development work with continuous miners in February 2025, and Company personnel and regulatory officials re-entered the sealed area of the mine on June 10, 2025. Thereafter, ventilation to the full mine was re-established, hydraulic pressure along the longwall face was restored and an extensive evaluation of the mine's major equipment and infrastructure was conducted. As expected, the longwall suffered insignificant damage from the combustion event, and major components and systems remained in good condition. On June 26, 2025, the operating team found it necessary to evacuate the mine again and began restoring pumpable seals to the affected area in the wake of an increase in carbon monoxide levels. In December 2025, the Company recovered the major longwall mining equipment, repositioned it and resumed longwall operations. Following the repositioning, the Company permanently sealed the affected area.
The Company incurred fire extinguishment and idle costs of $101 million at Leer South in 2025 for which it has pursued recoveries under its relevant insurance policies. In June 2026, the Company settled the Leer South insurance claim for total recoveries of $154.5 million, of which $135.1 million was recorded during the nine months ended September 30, 2026 and $19.4 million was recorded during the three and nine months ended September 30, 2025. Of the total recoveries of $154.5 million, the portion attributable to business interruption insurance was $114.9 million, which was recorded during the nine months ended September 30, 2026.
Our Business
We are a world-class producer and exporter of high-quality, low-cost coals, including metallurgical and thermal coals. We play an essential role in meeting the world's growing need for energy, steel, cement and other infrastructure solutions. Our products have global access due to our ownership interests in two marine export terminals and access to several other third-party owned terminals.
The Merger joined two proven leadership teams and operating platforms to establish Core, a premier North American coal producer and exporter of high-quality, low-cost coals with offerings ranging from metallurgical to high calorific value and other thermal coals. With mining operations and terminal facilities across six states, Core owns 11 mines, including one of the largest, lowest cost and highest calorific value thermal coal mining complexes in North America and one of the largest, lowest cost and highest quality metallurgical coal mine portfolios in the U.S. Core also has access to global markets via ownership interests in two export terminals on the U.S. Eastern seaboard, along with strategic connectivity to ports on the West Coast and the Gulf of America. The combined company expects to realize meaningful operating synergies through the optimization of support functions, greatly enhanced marketing opportunities and a significantly expanded logistics network, which will enhance the Company's ability to deliver coal reliably and efficiently to its global customers.
Results of Operations: Three Months Ended September 30, 2026 Compared with the Three Months Ended September 30, 2025
Revenues
The Company's revenues primarily include sales to customers of coal produced at our operations and, to a lesser extent, coal purchased from third parties. The Company's revenues also include third-party transloading services at the Port of Baltimore, as well as other revenues generated from customers.
Our mines in West Virginia produce a premium metallurgical product used in the global steel industry. Our surface mines in the Powder River Basin ("PRB") produce thermal coal for sale into domestic and international markets. Our thermal longwall mines produce a high-quality, high calorific value thermal product that can compete effectively in seaborne markets.
Consolidated revenues in the three months ended September 30, 2026 were $143 million higher than the three months ended September 30, 2025 due to increases in the High CV Thermal, Metallurgical, PRB and Core Marine Terminal segments of $66 million, $63 million, $9 million and $5 million, respectively. The increase in the High CV Thermal segment was mainly due to higher sales tons. The increase in the Metallurgical segment was primarily attributable to higher benchmark pricing, higher sales tons and a more favorable product mix compared to the prior year period. The increase in the PRB segment was largely attributable to higher sales tons in the current year period. See the discussion in "Operational Performance" below for further information about segment results.
Cost of Sales
Cost of sales includes items such as direct operating costs, royalties, production taxes and credits, direct administration costs and transportation costs. Our consolidated cost of sales in the three months ended September 30, 2026 increased $120 million compared to the three months ended September 30, 2025 principally due to increases in the High CV Thermal, Metallurgical, PRB and Core Marine Terminal segments of $81 million, $13 million, $13 million and $1 million, respectively. The increase in the High CV Thermal segment was primarily driven by higher sales tons as well as increased export logistics and transportation obligations compared to the prior year period. The increase in the Metallurgical segment was primarily due to increased sales tons, partially offset by the impact of Section 45X tax credits. The increase in the PRB segment was largely due to higher sales tons in the current year period and increased fuel costs due to higher diesel prices compared to the prior year period. In addition, cost of sales increased due to higher non-active mining costs when compared to the prior year period. See the discussion in "Operational Performance" below for further information about segment results.
Depreciation, Depletion and Amortization
On a consolidated basis, depreciation, depletion and amortization costs were $159 million for the three months ended September 30, 2026, compared to $151 million for the three months ended September 30, 2025. The increase was primarily due to additional assets placed into service.
General and Administrative Costs
On a consolidated basis, general and administrative costs were $25 million for the three months ended September 30, 2026, compared to $34 million for the three months ended September 30, 2025. The $9 million decrease in the period-to-period comparison was primarily due to lower Merger-related costs and ongoing synergies, specifically related to lower professional and consulting services and severance and benefit costs, as well as lower headcount.
Other Operating Income and Expense, net
Other operating income and expense, net consisted of the following items:
Three Months Ended September 30,
2026 2025 Variance
Royalty Income - Non-Operated Coal $ 6 $ 9 $ (3)
Land Holding and Administrative Costs (5) (10) 5
Other (8) (1) (7)
Total Other Operating Income and Expense, net $ (7) $ (2) $ (5)
Other includes various items, such as an increase in certain litigation costs of $4 million and various non-mining related costs, none of which were individually significant in either period.
Interest Expense and Interest Income
On a consolidated basis, interest expense was $10 million for the three months ended September 30, 2026, compared to $11 million for the three months ended September 30, 2025.
Interest income decreased $2 million in the period-to-period comparison primarily due to changes in interest rates.
Non-Service Related Pension and Postretirement Benefit Costs
Non-service related pension and postretirement benefit costs decreased $1 million in the period-to-period comparison primarily due to the impact of changes in actuarial assumptions made at the beginning of each year.
Results of Operations: Nine Months Ended September 30, 2026 Compared with the Nine Months Ended September 30, 2025
Revenues
Consolidated revenues in the nine months ended September 30, 2026 were $248 million higher than the nine months ended September 30, 2025 due to increases in the High CV Thermal, Metallurgical and Core Marine Terminal segments of $83 million, $167 million and $12 million, respectively, partially offset by a decrease in the PRB segment of $17 million. The increase in the High CV Thermal segment was mainly due to higher sales tons. The increase in the Metallurgical segment was primarily attributable to higher benchmark pricing, higher sales tons and a more favorable product mix compared to the prior year period. The decrease in the PRB segment was largely attributable to lower sales tons. See the discussion in "Operational Performance" below for further information about segment results.
Cost of Sales
Our consolidated cost of sales in the nine months ended September 30, 2026 increased $105 million compared to the nine months ended September 30, 2025 primarily due to increases in the High CV Thermal, PRB and Core Marine Terminal segments of $128 million, $29 million and $3 million, respectively, partially offset by a $48 million decrease in the Metallurgical segment. The increase in the High CV Thermal segment was primarily related to higher sales tons and increased export logistics and transportation obligations compared to the prior year period. Our operations were impacted by increased electricity, fuel and explosives costs due to higher diesel prices compared to the prior year period, which were primary drivers for the increased cost of sales in the PRB segment compared to the prior year period. The decrease in the Metallurgical segment was primarily due to a production decrease at our higher-cost continuous miner operations as well as the impact of Section 45X tax credits, partially offset by a production increase at our lower-cost longwall operations. In addition to these changes, non-active mining costs decreased when compared to the prior year period, which partially offset the overall increase. See the discussion in "Operational Performance" below for further information about segment results.
Depreciation, Depletion and Amortization
On a consolidated basis, depreciation, depletion and amortization costs were $472 million for the nine months ended September 30, 2026, compared to $442 million for the nine months ended September 30, 2025, resulting in a $31 million increase. The increase was primarily attributable to additional assets placed into service.
General and Administrative Costs
On a consolidated basis, general and administrative costs were $88 million for the nine months ended September 30, 2026, compared to $158 million for the nine months ended September 30, 2025. The $70 million decrease in the period-to-period comparison was primarily due to non-recurring Merger-related transaction costs incurred during the nine months ended September 30, 2025, including fees paid to financial, legal and accounting advisors, severance and benefit costs, filing fees and debt restructuring costs. The remaining decrease related to lower headcount resulting from the synergies of the Merger.
Other Operating Income and Expense, net
Other operating income and expense, net consisted of the following items:
Nine Months Ended September 30,
2026 2025 Variance
Business Interruption Insurance Proceeds $ 121 $ 1 $ 120
Royalty Income - Non-Operated Coal 18 23 (5)
Gain on Sale of Assets 6 6 -
Land Holding and Administrative Costs (20) (19) (1)
Other (25) (8) (17)
Total Other Operating Income and Expense, net $ 100 $ 3 $ 97
Business interruption insurance proceeds recorded in the nine months ended September 30, 2026 related to the final resolutions of the Leer South and the Francis Scott Key Bridge collapse insurance claims.
Other includes various items, such as the change in the provision for expected credit losses of $4 million, an increase in certain litigation costs of $6 million and various non-mining related costs, none of which were individually significant in either period.
Interest Expense and Interest Income
On a consolidated basis, interest expense was $33 million for the nine months ended September 30, 2026, compared to $29 million for the nine months ended September 30, 2025. The $4 million increase in the period-to-period comparison was primarily due to interest incurred on new equipment financing arrangements, as well as additional interest on the Series 2025 Bonds (as defined below).
Interest income decreased $5 million in the period-to-period comparison primarily due to changes in interest rates.
Loss on Debt Extinguishment
Loss on debt extinguishment of $12 million was recorded in the nine months ended September 30, 2025 due to the amendment of the Company's Revolving Credit Facility and the refinancing of the Series 2025 Bonds.
Non-Service Related Pension and Postretirement Benefit Costs
Non-service related pension and postretirement benefit costs decreased $2 million in the period-to-period comparison primarily due to the impact of changes in actuarial assumptions made at the beginning of each year.
How We Evaluate Our Operations
Our management team uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability. The metrics include: (i) coal production and sales volumes; (ii) realized coal revenue, a non-GAAP financial measure; (iii) realized coal revenue per ton sold, an operating ratio derived from non-GAAP financial measures; (iv) cash cost of coal sold, a non-GAAP financial measure; (v) cash cost of coal sold per ton, an operating ratio derived from non-GAAP financial measures; (vi) cash margin per ton sold, an operating ratio derived from non-GAAP financial measures, defined as realized coal revenue per ton sold less cash cost of coal sold per ton; and (vii) adjusted EBITDA, a non-GAAP financial measure.
We believe that realized coal revenue and realized coal revenue per ton sold better reflect our revenue for the quality of coal sold and our operating results by including all income from coal sales. We believe cash cost of coal sold, cash cost
of coal sold per ton and cash margin per ton sold normalize the volatility contained within comparable measures prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP") by adjusting for certain non-operating or non-cash transactions. We believe that adjusted EBITDA provides a helpful measure of comparing our operating performance with the performance of other companies that have different financing, capital structures and tax rates than ours. Each of these non-GAAP measures is used as a supplemental financial measure by management and by external users of our financial statements, such as investors, industry analysts, lenders and ratings agencies, to assess:
•our operating performance compared to the operating performance of other companies in the coal industry, without regard to financing methods, historical cost basis, tax rates or capital structure;
•the ability of our assets to generate sufficient cash flow;
•our ability to incur and service debt and fund capital expenditures;
•the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities; and
•the attractiveness of capital projects and acquisitions and the overall rates of return on alternative investment opportunities.
These non-GAAP financial measures should not be considered an alternative to revenues, cost of sales, net income (loss) or any other measure of financial performance presented in accordance with GAAP. These measures exclude some, but not all, items that affect measures presented in accordance with GAAP, and these measures and the way we calculate them may vary from those of other companies. As a result, the items presented below may not be comparable to similarly titled measures of other companies.
Reconciliation of Non-GAAP Financial Measures
We define realized coal revenue as revenues reported in the Condensed Consolidated Statements of Income (Loss) less transportation costs, transloading revenues and other revenues not directly attributable to coal sales. We define realized coal revenue per ton sold as realized coal revenue divided by tons sold. The following tables present reconciliations by reportable segment of realized coal revenue and realized coal revenue per ton sold to revenues, the most directly comparable GAAP financial measure (in thousands, except per ton information):

See "How We Evaluate Our Operations-Reconciliation of Non-GAAP Financial Measures" above for definitions and reconciliations of these amounts to the most directly comparable GAAP measures.
High CV Thermal Segment Analysis
Adjusted EBITDA decreased $15 million in the period-to-period comparison, primarily due to a $3.20 decrease in realized coal revenue per ton sold and a $0.91 increase in cash cost of coal sold per ton, partially offset by an increase in tons sold. The decrease in realized coal revenue per ton sold was primarily related to a less favorable product mix compared to the prior year period. The increase in cash cost of coal sold per ton was primarily due to elevated maintenance and contractor expenses and increased electricity costs, partially offset by the impact of Section 45X tax credits in the current year period.
Metallurgical Segment Analysis
Adjusted EBITDA increased $49 million in the period-to-period comparison, primarily due to an $18.58 increase in realized coal revenue per ton sold and higher tons sold. In addition, cash cost of coal sold per ton decreased $1.26. The increase in realized coal revenue per ton sold largely related to increased coal benchmark pricing and a more favorable product mix when compared to the prior year period. The decrease in cash cost of coal sold per ton was primarily due to
higher sales tons from restarting our Leer South longwall mine, which has a lower operating cost per ton than our continuous miner operations, as well as the impact of Section 45X tax credits.
PRB Segment Analysis
Adjusted EBITDA decreased $3 million in the period-to-period comparison, primarily due to a $0.45 increase in cash cost of coal sold per ton, which was negatively impacted by increased fuel and explosives costs due to higher diesel prices compared to the prior year period. The decrease in adjusted EBITDA was partially offset by a $0.20 increase in realized coal revenue per ton sold and a 0.5 million increase in tons sold.
Core Marine Terminal Segment Analysis
Adjusted EBITDA increased $4 million in the period-to-period comparison, primarily due to higher throughput tons. Throughput volumes at the Core Marine Terminal were 4.8 million tons for the three months ended September 30, 2026, compared to 4.0 million tons for the three months ended September 30, 2025.

See "How We Evaluate Our Operations-Reconciliation of Non-GAAP Financial Measures" above for definitions and reconciliations of these amounts to the most directly comparable GAAP measures.
High CV Thermal Segment Analysis
Adjusted EBITDA decreased $45 million in the period-to-period comparison, primarily due to a $3.28 decrease in realized coal revenue per ton sold, partially offset by higher tons sold and a decrease in cash cost of coal sold per ton. The decrease in realized coal revenue per ton sold was principally related to a less favorable product mix compared to the prior year period. The decrease in cash cost of coal sold per ton was largely due to higher sales tons to absorb fixed costs on a per ton basis compared to the prior year period.
Metallurgical Segment Analysis
Adjusted EBITDA increased $329 million in the period-to-period comparison, primarily due to insurance recoveries related to the Leer South insurance claim of $135 million in the current year period compared to fire extinguishment and idle costs of $76 million, partially offset by $19 million of insurance reimbursements, in the prior year period. Current year adjusted EBITDA was also positively impacted by a $14.10 increase in realized coal revenue per ton sold and a $3.46 decrease in cash cost of coal sold per ton. The increase in realized coal revenue per ton sold largely related to increased coal benchmark pricing and a more favorable product mix when compared to the prior year period. The decrease in cash cost of coal sold per ton was primarily due to higher sales tons from restarting our Leer South longwall mine, which has a lower operating cost per ton than our continuous miner operations, as well as the impact of Section 45X tax credits.
PRB Segment Analysis
Adjusted EBITDA decreased $43 million in the period-to-period comparison, primarily due to a 0.7 million decrease in tons sold and a $0.94 increase in cash cost of coal sold per ton. In addition to lower sales tons to absorb fixed costs, cash cost of coal sold per ton was negatively impacted by increased fuel and explosives costs due to higher diesel prices compared to the prior year period.
Core Marine Terminal Segment Analysis
Adjusted EBITDA increased $10 million in the period-to-period comparison, primarily due to increased throughput tons. Throughput volumes at the Core Marine Terminal were 14.8 million tons for the nine months ended September 30, 2026, compared to 13.2 million tons for the nine months ended September 30, 2025.
Liquidity and Capital Resources
The Company's potential sources of liquidity include cash generated from operating activities, cash on hand, short-term investments, borrowings under the Revolving Credit Facility and Receivables Financing Agreement (which are discussed and defined below) and, if necessary, the ability to issue equity or debt securities. The Company believes that cash generated from these sources, without needing to issue equity or debt securities, will be sufficient to meet its short-term working capital requirements, long-term capital expenditure requirements and debt servicing obligations, as well as to provide required letters of credit or surety bonds necessary for the Company's operations.
Our total liquidity as of September 30, 2026 comprised the following:
(in millions) September 30, 2026
Cash, Cash Equivalents and Short-Term Investments $ 444
Receivables Financing Agreement - Current Availability 250
Revolving Credit Facility - Current Availability 600
Less: Letters of Credit Outstanding (266)
Total Liquidity $ 1,028
Events that negatively impact our operations, overall financial condition and liquidity could result in our inability to comply with the Revolving Credit Facility's financial covenants. This could limit our ability to borrow under the Revolving Credit Facility if we are unable to obtain necessary waivers or amendments. The Company expects to maintain adequate liquidity through its net cash provided by operating activities, cash and cash equivalents on hand and short-term investments, as well as the Revolving Credit Facility and its Receivables Financing Agreement, to fund its working capital needs and capital expenditures in the short-term and long-term.
Uncertainty in the financial markets, tariffs, foreign conflicts and executive actions by the executive branch of the U.S. Government and certain other foreign nations or sovereignties bring additional potential risks to the Company. These
risks could impact our ability to raise capital in the equity and debt markets or result in higher costs to obtain additional capital or credit, as well as increase potential counterparty defaults. In addition, market disruptions and uncertainty, arising from current and potential tariffs, executive actions, elevated interest rates, sustained high inflation and supply chain disruptions such as those stemming from the conflict in Iran, may impact the Company's revenues and collections, as well as its overall cost of operations, including recent increases in diesel fuel and other commodity prices. The Company regularly monitors the creditworthiness of its customers and counterparties and manages credit exposure through payment terms, credit limits, prepayments and security.
The global landscape on rates and the scope of tariffs imposed on goods imported into and out of the U.S. from multiple countries around the world continues to evolve and be uncertain, as the U.S. Government continues to negotiate its position with multiple countries and across various industries and goods. While the evolving global trade landscape relating to tariffs and retaliatory trade measures imposed by other countries on U.S. goods has not yet had a significant impact on our business or results of operations as of September 30, 2026, this and the potential for additional changes in U.S. or international trade policy have increased uncertainty regarding the ultimate effect of the tariffs on economic conditions and could lead to further weakened business conditions for the coal industry.
Over the past few years, the insurance and surety markets had been increasingly challenging, particularly for coal companies. We had experienced rising premiums, reduced coverage and fewer providers willing to underwrite policies and surety bonds. Terms had become generally unfavorable, including increases in the amount of collateral required to secure surety bonds. However, more recently, we have seen insurance rates and collateral requirements stabilize and even decrease on certain lines of coverage, as new insurance carriers have entered the market. Further cost burdens on our ability to maintain adequate insurance and bond coverage may adversely impact our operations, financial position and liquidity.
At September 30, 2026, the Company had a $135 million fund in place that will cover, in part, future reclamation costs of the thermal assets in the PRB. Additionally, the Company maintains $21 million in water treatment trust funds that will fund future water treatment obligations in Pennsylvania, as well as replace surety bonds and related collateral requirements. The Company expects to continue to contribute a minimum of $2 million per year to the water treatment trust funds. These amounts are included in Funds for Asset Retirement Obligations on the Condensed Consolidated Balance Sheets.
In December 2024, the Office of Workers' Compensation Programs (the "OWCP") issued a final rule revising the regulations under the Black Lung Benefits Act related to self-insurance by coal mine operators. Under the new standard, self-insured coal mine operators are required to post additional security for the Black Lung benefit liabilities. The final rule requires a security amount equal to 100% of a self-insured operator's projected black lung liabilities. The rule became effective on January 13, 2025, and operators were required to remit the increased security amount within one year. In February 2025, the Company received letters from the OWCP that additional guidance regarding the final rule will be provided at a future date. In July 2026, the OWCP published a proposed rule that would amend the regulations under the Black Lung Benefits Act to eliminate the 100% security requirement for all operators and instead require a financial review of each operator to calculate a Composite Solvency Score ("CSS"). The CSS determines the percentage of security that companies will be required to provide relative to total black lung liabilities. The Company is currently evaluating the potential impacts of the proposed rule, and any increased security requirement as a result of these proposed changes could adversely impact our financial position and liquidity.
The Company participates in the United Mine Workers of America (the "UMWA") Combined Benefit Fund and the UMWA 1992 Benefit Plan for which benefits are reflected in the Company's consolidated financial statements when paid. These benefit arrangements may result in additional liabilities that are not recognized on the Condensed Consolidated Balance Sheet at September 30, 2026. The various multi-employer benefit plans are discussed in Note 17-Other Employee Benefit Plans in the Notes to the Audited Consolidated Financial Statements in Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The Company's total contributions under the Coal Industry Retiree Health Benefit Act of 1992 were $2 million for both the nine months ended September 30, 2026 and 2025. The Company also uses a combination of surety bonds, corporate guarantees and letters of credit to secure its financial obligations for employee-related, environmental, performance and various other items that are not reflected on the Condensed Consolidated Balance Sheet at September 30, 2026. Management believes these items will expire without being funded. See Note 14-Commitments and Contingent Liabilities in the Notes to the Condensed Consolidated Financial Statements included in this Report for additional details of the various financial guarantees that have been issued by the Company.
Cash Flows (in millions)
Nine Months Ended September 30,
2026 2025 Variance
Net Cash Provided by Operating Activities $ 544 $ 198 $ 346
Net Cash (Used in) Provided by Investing Activities $ (305) $ 132 $ (437)
Net Cash Used in Financing Activities $ (239) $ (166) $ (73)
Net cash provided by operating activities increased by $346 million in the period-to-period comparison primarily due to increased segment earnings, including recoveries related to the Leer South insurance claim, as well as the payment of non-recurring Merger-related expenditures in the nine months ended September 30, 2025.
Net cash (used in) provided by investing activities changed by $437 million in the period-to-period comparison primarily due to the Merger, which included cash acquired of $369 million, partially offset by the purchase of Arch's tax-exempt bonds of $98 million. During the current year period, the Company purchased $17 million of short-term investments, compared with $75 million of net proceeds from the liquidation of its U.S. Treasury securities during the nine months ended September 30, 2025. Additionally, capital expenditures increased $66 million compared to the prior year period primarily due to increased airshaft and refuse area spend.
Net cash used in financing activities increased by $73 million in the period-to-period comparison. In connection with the Merger, the Company amended its Revolving Credit Facility, refinanced its tax-exempt bonds and amended the legacy Arch securitization facility during the nine months ended September 30, 2025. Proceeds of $114 million were received in connection with the bond refinancing, and fees associated with these transactions amounted to $20 million. Dividend payments decreased by $6 million compared to the prior year period. Additionally, cash outflows related to share repurchases totaled $190 million in the nine months ended September 30, 2026 compared to $203 million in the nine months ended September 30, 2025.
Revolving Credit Facility
In November 2017, the Company entered into a revolving credit facility with PNC Bank, National Association ("PNC") (as amended, the "Revolving Credit Facility"). The Revolving Credit Facility has been amended several times, the most recent of which occurred in January 2025 in connection with the Merger. The January 2025 amendment increased the available revolving commitments from $355 million to $600 million and extended the scheduled maturity date to April 30, 2029, provided that, if any of the MEDCO Bonds or PEDFA Bonds (as defined below) and any subsequent refinancings thereof remain outstanding 91 days prior to their stated maturity and our specified liquidity, as measured under the Revolving Credit Facility, is less than $250 million at that time, the maturity date of the Revolving Credit Facility will be such date. Additionally, the Company reduced the applicable interest rate margin on its borrowings and letters of credit under the Revolving Credit Facility by 75 basis points.
Borrowings under the Revolving Credit Facility may be used for general corporate purposes, including working capital, capital expenditures and permitted acquisitions. Amounts repaid under the Revolving Credit Facility may be reborrowed, subject to satisfaction of the conditions to each credit extension. The Revolving Credit Facility provides that up to the full amount of the facility may be used for the issuance of letters of credit (the "Letters of Credit") by each lender under the Revolving Credit Facility, including Arch letters of credit that are deemed to be issued under the Revolving Credit Facility. The Company may increase the revolving credit commitments on the same terms or incur term "A" loans, in each case in an aggregate amount of up to $150 million.
Borrowings under the Revolving Credit Facility bear interest at a floating rate that is, at the Company's option, either (i) the applicable term Secured Overnight Financing Rate ("SOFR") plus a SOFR adjustment of 0.10% plus an applicable margin or (ii) an alternate base rate plus an applicable margin. The applicable margin for the Revolving Credit Facility ranges from 3.00% to 3.75% (for SOFR loans) and 2.00% to 2.75% (for alternate base rate loans), depending on the total net leverage ratio.
The Company's obligations under the Revolving Credit Facility are fully and unconditionally guaranteed by subsidiaries of the Company that own any portion of the Pennsylvania Mining Complex, the Core Marine Terminal and specified coal reserves and, subject to certain customary exceptions, all other existing or future direct or indirect wholly-owned material restricted subsidiaries of the Company, including subsidiaries acquired pursuant to the Merger. The obligations under the Revolving Credit Facility are secured by, subject to certain exceptions (including a limitation on pledges of equity interests in certain subsidiaries and certain thresholds with respect to real property), a first-priority lien on the Company's and certain subsidiaries' significant assets.
The Revolving Credit Facility contains a number of customary affirmative covenants and a number of negative covenants, including (subject to certain exceptions) limitations on (among other things): indebtedness, liens, investments, acquisitions, asset dispositions, restricted payments, mergers, consolidations, divisions and other fundamental changes, transactions with affiliates and prepayments of junior indebtedness. The Revolving Credit Facility requires prepayment of Revolving Credit Loans and Swing Loans if (x) Excess Balance Sheet Cash is greater than $125 million and (y) the sum of Revolving Credit Loans, Swing Loans and Letter of Credit Obligations (other than in respect of undrawn Letters of Credit) is greater than 25% of the Revolving Credit Commitments, in each case as of the last day of any calendar month.
The Revolving Credit Facility also includes financial covenants relating to (i) a maximum first lien gross leverage ratio, (ii) a maximum total net leverage ratio, and (iii) a minimum interest coverage ratio. Under the Revolving Credit Facility, the maximum first lien gross leverage ratio is 1.50 to 1.00, the maximum total net leverage ratio is 2.50 to 1.00 and the minimum interest coverage ratio is 3.00 to 1.00. The Revolving Credit Facility contains customary events of default, including failure to make payments when due, cross-default and cross-judgment default and certain bankruptcy and insolvency events.
The Company's first lien gross leverage ratio was 0.19 to 1.00 at September 30, 2026. The Company's total net leverage ratio was 0.01 to 1.00 at September 30, 2026. The Company's interest coverage ratio was 31.93 to 1.00 at September 30, 2026. The Company was in compliance with all covenants under the Revolving Credit Facility as of September 30, 2026.
At September 30, 2026, the Revolving Credit Facility had no borrowings outstanding and $78 million of letters of credit outstanding, leaving $522 million of unused borrowing capacity. From time to time, the Company is required to post financial assurances to satisfy contractual and other requirements generated in the normal course of business. Some of these assurances are posted to comply with federal, state or other government agencies' statutes and regulations. The Company sometimes uses letters of credit to satisfy these requirements, and these letters of credit reduce the Company's borrowing facility capacity.
Receivables Financing Agreement
Certain U.S. subsidiaries of the Company are parties to a trade accounts receivable securitization facility with financial institutions for the sale on a continuous basis of eligible trade accounts receivable. On July 28, 2025, the Company and certain of its subsidiaries entered into (i) that certain Receivables Financing Agreement (the "Receivables Financing Agreement"), by and among Core Receivable Company, LLC, as borrower ("Core Receivable"), Core Sales, LLC, as the initial servicer (the "Servicer"), PNC, as administrative agent and LC bank, PNC Capital Markets LLC ("PNC CM"), as structuring agent, and the lenders from time to time party thereto; (ii) that certain Third Amended and Restated Sale and Contribution Agreement (the "Sale and Contribution Agreement"), by and among Core Receivable, the Servicer and Arch, as transferor; (iii) that certain Third Amended and Restated Purchase and Sale Agreement (the "Purchase and Sale Agreement"), by and among Arch, the Servicer and the originators party thereto; and (iv) that certain Fifth Amended and Restated Performance Guaranty (the "Performance Guaranty" and, together with the Receivables Financing Agreement, the Sale and Contribution Agreement and the Purchase and Sale Agreement, the "Receivables Documents"), by the Company, in favor of PNC as administrative agent. With entry into the Receivables Documents, legacy Arch's securitization facility was amended and restated in its entirety to, among other things, consolidate facilities and extend the maturity date to July 27, 2028, and legacy CONSOL's securitization facility was terminated effective July 28, 2025.
Pursuant to the Receivables Documents, Core Sales, LLC; Mingo Logan Coal LLC; Mountain Coal Company, L.L.C.; ICG Beckley, LLC; ICG Tygart Valley, LLC; Wolf Run Mining LLC; Thunder Basin Coal Company, L.L.C.; CONSOL Pennsylvania Coal Company LLC; Core Marine Terminals LLC; and Itmann Mining Company LP, all wholly-owned subsidiaries of the Company, sell or contribute trade receivables to Core Receivable, a special purpose vehicle and wholly-owned subsidiary of the Company. Core Receivable, in turn, pledges its interests in the receivables to PNC and Regions Bank, each of which either makes loans or issues letters of credit on behalf of Core Receivable. The maximum amount of advances and letters of credit outstanding under the Receivables Financing Agreement may not exceed $250 million.
Loans under the Receivables Financing Agreement accrue interest at a reserve-adjusted market index rate equal to the applicable term SOFR plus ten basis points. Loans and letters of credit under the Receivables Financing Agreement also accrue a drawn fee and a letter of credit participation fee, respectively, of 2.00% per annum. In connection with the Receivables Financing Agreement, Core Receivable paid certain structuring fees to PNC CM and pays other customary fees to the lenders, including a fee on unused commitments equal to 0.60% per annum.
The Receivables Documents contain various customary representations and warranties, covenants and default provisions that provide for the termination and acceleration of the commitments and loans under the Receivables Financing Agreement in certain circumstances including, but not limited to, failure to make payments when due, breach of
representation, warranty or covenant, certain insolvency events or failure to maintain the security interest in the trade receivables, and defaults under other material indebtedness. The Company guarantees the performance of the obligations of Arch; Core Sales, LLC; Mingo Logan Coal LLC; Mountain Coal Company, L.L.C.; ICG Beckley, LLC; ICG Tygart Valley, LLC; Wolf Run Mining LLC; Thunder Basin Coal Company, L.L.C.; CONSOL Pennsylvania Coal Company LLC; Core Marine Terminals LLC; and Itmann Mining Company LP under the securitization, and will guarantee the obligations of any additional originators or successor servicer that may become party to the Receivables Financing Agreement. However, neither the Company nor its affiliates will guarantee collectability of receivables or the creditworthiness of obligors thereunder.
At September 30, 2026, the Company's eligible accounts receivable yielded $250 million of borrowing capacity. At September 30, 2026, the Receivables Financing Agreement had no borrowings outstanding and $188 million of letters of credit outstanding, leaving $62 million of unused borrowing capacity. The Company has not derecognized any receivables due to its continued involvement in the collections efforts.
Series 2025 Bonds

Critical Accounting Estimates
The Company prepares its financial statements in accordance with GAAP. The preparation of these financial statements requires management to make judgments, estimates and assumptions that affect the reported amount of assets, liabilities, revenues and expenses, as well as the disclosure of contingent assets and liabilities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. There have been no material changes to the Company's critical accounting estimates from the Annual Report on Form 10-K for the year ended December 31, 2025.
Forward-Looking Statements
Certain statements in this Report are "forward-looking statements" within the meaning of the federal securities laws. With the exception of historical matters, the matters discussed in this Report are forward-looking statements (as defined in Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) that involve risks and uncertainties that could cause actual results and outcomes to differ materially from results expressed in or implied by our forward-looking statements. Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. The forward-looking statements may include projections and estimates concerning the timing and success of specific projects and our future production, revenues, income and capital spending. When we use the words "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "plan," "predict," "project," "should," "will," "would," or their negatives, or other similar expressions, the statements that include those words are usually forward-looking statements.

We disclaim any obligation to update these statements unless required by securities law, and we caution you not to rely on them unduly. We have based these forward-looking statements on our current expectations and assumptions about future events. While management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. These risks, contingencies and uncertainties relate to, among other matters, the following:

•coal users switching to other fuels in order to comply with various environmental standards related to coal combustion emissions;
•the impact of current and future regulations to address climate change, the discharge, disposal and clean-up of hazardous substances and wastes and employee health and safety on our operating costs as well as on the market for coal;
•the risks inherent in coal operations, including being subject to unexpected disruptions caused by adverse geological conditions, equipment failure, delays in moving longwall equipment, railroad derailments or strikes, security breaches or terroristic acts and other hazards, delays in the completion of significant construction or repair of equipment, fires, explosions, seismic activities, accidents and weather conditions;
•failure to obtain or renew surety bonds, letters of credit or insurance coverages on acceptable terms;
•the effects of coordinating our operations with oil and natural gas drillers and distributors operating on our land;

•the effects of our securities being excluded from certain investment funds as a result of environmental, social and corporate governance practices;
•the effects of global conflicts on commodity prices and supply chains;
•the effect of new or existing laws, regulations, tariffs, executive orders or other trade measures;
•our inability to find suitable joint venture partners, acquisition targets or similar investments or to integrate the operations of future acquisitions or investments into our operations;
•obtaining, maintaining and renewing government permits and approvals for our coal operations;
•the effects of asset retirement obligations, employee-related long-term liabilities and certain other liabilities;

The above list of factors is not exhaustive or necessarily in order of importance. Additional information concerning factors that could cause actual results to differ materially from those in forward-looking statements include those discussed under "Risk Factors" elsewhere in this Report and the other filings we make with the Securities and Exchange Commission ("SEC").
