NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

(Dollars in thousands, except per share data)

NOTE 1—BASIS OF PRESENTATION:

Basis of Presentation

The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for future periods.

The Consolidated Balance Sheet at December 31, 2023 has been derived from the Audited Consolidated Financial Statements at that date but does not include all disclosures required by GAAP. This Form 10-Q report should be read in conjunction with CONSOL Energy Inc.'s Annual Report on Form 10-K for the year ended December 31, 2023.

All dollar amounts discussed in these Notes to Consolidated Financial Statements are in thousands of U.S. dollars, except for per share amounts, and unless otherwise indicated.

Basis of Consolidation

The Consolidated Financial Statements include the accounts of CONSOL Energy Inc. and its wholly-owned and majority-owned and/or controlled subsidiaries. All significant intercompany transactions and accounts have been eliminated in consolidation.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09 Income Taxes (Topic 740). The amendments in this update address investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation, (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than five percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate), (3) disclose the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes, (4) disclose the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received), (5) disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign, and (6) disclose income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. The amendments in this update are effective for annual periods beginning after December 15, 2024, and should be applied prospectively. Management is currently evaluating the impact of this guidance, but does not expect this update to have a material impact on the Company's financial statements.

In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280). The amendments in this update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. Topic 280 requires a public entity to report a measure of segment profit or loss that the chief operating decision maker uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment items and amounts, such as depreciation, amortization, and depletion expense, to be disclosed under certain circumstances. The amendments in this update do not change or remove those disclosure requirements. The amendments in this update also do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 and should be applied retrospectively. Management is currently evaluating the impact of this guidance, but does not expect this update to have a material impact on the Company's financial statements.

Table of Contents

In August 2023, the FASB issued ASU 2023-05 - Business Combinations—Joint Venture Formations (Subtopic 805-60). The amendments in this update address the accounting for contributions made to a joint venture, upon formation, in a joint venture's separate financial statements. The objectives of the amendments are to (1) provide decision-useful information to investors and other allocators of capital in a joint venture's financial statements and (2) reduce diversity in practice. The amendments in this update do not amend the definition of a joint venture, the accounting by an equity method investor for its investment in a joint venture, or the accounting by a joint venture for contributions received after its formation. The amendments in this update are effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. Existing joint ventures may elect to apply the guidance retrospectively. Management is currently evaluating the impact of this guidance, but does not expect this update to have a material impact on the Company's financial statements.

Earnings per Share

Basic earnings per share are computed by dividing net income by the weighted average number of shares outstanding during the reporting period. Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average number of shares outstanding is increased to include additional shares from restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities, as applicable, were used to acquire shares of common stock at the average market price during the reporting period.

The table below sets forth the share-based awards that have been excluded from the computation of diluted earnings per share because their effect would be anti-dilutive:


	Three Months Ended June 30,		Six Months Ended June 30,

Anti-Dilutive Restricted Stock Units	319	470	355	331
Anti-Dilutive Performance Share Units	—	—	—	—
	319	470	355	331

The computations for basic and dilutive earnings per share are as follows:

Coal Revenue

The Company has disaggregated its coal revenue, derived from the PAMC and the Itmann Mining Complex, between domestic and export revenues, as well as between the industrial, power generation and metallurgical markets. Domestic coal revenue tends to be derived from contracts that typically have a term of one year or longer, and the pricing is typically fixed. Historically, export coal revenue tended to be derived from spot or shorter-term contracts with pricing determined closer to the time of shipment or based on a market index; however, the Company has secured several long-term export contracts with varying pricing arrangements. Coal revenue derived from the Itmann Mining Complex consists primarily of metallurgical coal sales, while coal revenue derived from the PAMC services the industrial, power generation and metallurgical markets due to the nature of its coal quality characteristics.

CONSOL Energy's coal revenue is recognized when the performance obligation has been satisfied, and the corresponding transaction price has been determined. Generally, title passes when coal is loaded at the coal preparation facilities, at terminal locations or other customer destinations. The Company's coal contract revenue per ton is fixed or determinable based upon either fixed forward pricing or pricing derived from established indices and adjusted for nominal quality characteristics. Some coal contracts also contain positive electric power price-related adjustments, which represent market-driven price adjustments, in addition to a fixed base price per ton. The Company’s coal contracts generally do not allow for retroactive adjustments to pricing after title to the coal has passed and typically do not have significant financing components.

The estimated transaction price from each of the Company's contracts is based on the total amount of consideration to which the Company expects to be entitled under the contract. Included in the transaction price for certain coal supply contracts is the impact of variable consideration, including quality price adjustments, handling services and per ton price fluctuations based on certain coal sales price indices. The estimated transaction price for each contract is allocated to the Company's performance obligations based on relative stand-alone selling prices determined at contract inception. The Company has determined that each ton of coal represents a separate and distinct performance obligation.

While CONSOL Energy does, from time to time, experience costs of obtaining coal customer contracts with amortization periods greater than one year, those costs are generally immaterial. At June 30, 2024 and December 31, 2023, the Company did not have any capitalized costs to obtain customer contracts on its Consolidated Balance Sheets. As of and for the three and six months ended June 30, 2024 and 2023, the Company has not recognized any amortization of previously existing capitalized costs of obtaining customer contracts. Further, the Company has not recognized any coal revenue in the current period that is not a result of current period performance.

Terminal Revenue

Terminal revenues are attributable to the Company's CONSOL Marine Terminal and include revenues earned from providing receipt and unloading of coal from rail cars, transporting coal from the receipt point to temporary storage or stockpile facilities located at the Terminal, stockpiling, blending, weighing, sampling, redelivery, and loading of coal onto vessels. Revenues for these services are earned and performance obligations are considered fulfilled as the services are performed.

The CONSOL Marine Terminal does not normally experience material costs of obtaining customer contracts with amortization periods greater than one year. At June 30, 2024 and December 31, 2023, the Company did not have any capitalized costs to obtain customer contracts on its Consolidated Balance Sheets. As of and for the three and six months ended June 30, 2024 and 2023, the Company has not recognized any amortization of previously existing capitalized costs of obtaining Terminal customer contracts. Further, the Company has not recognized any Terminal revenue in the current period that is not a result of current period performance.

Freight Revenue

Some of CONSOL Energy's coal contracts require that the Company sell its coal at locations other than its coal preparation plants. The cost to transport the Company's coal to the ultimate sales point is passed through to the Company's customers and CONSOL Energy recognizes the freight revenue equal to the transportation costs when title to the coal passes to the customer.

Other Revenue

Other revenue consists of revenue generated from carbon products and materials businesses led by CONSOL Innovations LLC, our wholly-owned subsidiary. This revenue is primarily comprised of sales of composite tools that are used in the aerospace industry. Revenues for these products are earned and recognized as the tools are built and progress toward product completion. Additionally, other revenue consists of revenue generated from the processing of third-party

Table of Contents

coal at the Itmann Mining Complex. Revenues for these services are earned and performance obligations are considered fulfilled as the services are performed. Other revenue is included within Miscellaneous Other Income in the accompanying Consolidated Statements of Income.

Contract Balances

Contract assets, when present, are recorded separately from trade receivables in the Company's Consolidated Balance Sheets and are reclassified to trade receivables as title passes to the customer and the Company's right to consideration becomes unconditional. Credit is extended based on an evaluation of a customer's financial condition and a customer's ability to perform its obligations. CONSOL Energy typically does not have material contract assets that are stated separately from trade receivables since the Company's performance obligations are satisfied as control of the goods or services passes to the customer, thereby granting the Company an unconditional right to receive consideration. Contract liabilities relate to consideration received in advance of the satisfaction of the Company's performance obligations. Contract liabilities are recognized as revenue at the point in time when control of the goods passes to the customer, or over time when services are provided.

Interest and dividends are included in net income when earned.

NOTE 7—CREDIT LOSSES:

Trade receivables are recorded at the invoiced amount. Credit is extended based on an evaluation of a customer's financial condition, the importance of the customer or market for future business and a customer's ability to perform its obligations. Trade receivable balances are monitored against approved credit terms. Credit terms are reviewed and adjusted as considered necessary based on changes to a customer's credit profile. If a customer's credit deteriorates, the Company may reduce credit risk exposure by reducing credit terms, obtaining letters of credit, obtaining credit insurance, or requiring pre-payment for shipments. Other non-trade contractual arrangements consist primarily of overriding royalty agreements and other financial arrangements between the Company and various counterparties.

The Company may be at risk of exposure to credit losses primarily through sales of products and services. The Company's expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers' trade and other accounts receivables. Due to the short-term nature of such receivables, the estimate of the amount of accounts receivable that may not be collected is based on an aging of the accounts receivable balances and the financial condition of customers. Additionally, specific allowance amounts may be necessary from time to time and are established to record the appropriate provision for customers that have a higher probability of default. The Company's monitoring activities include timely account reconciliations, dispute resolution, payment confirmation, and consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible.

Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for changes to the assessment of anticipated payment, changes in economic conditions, current industry trends in the markets the Company serves, and changes in the financial health of the Company's counterparties.

The following table provides a roll-forward of the allowance for credit losses that is deducted from the amortized cost basis of accounts receivable and other non-trade contractual arrangements to present the net amount expected to be collected.

The cost of supplies inventory is determined by the average cost method and includes operating and maintenance supplies to be used in the Company's coal operations.

NOTE 9—ACCOUNTS RECEIVABLE SECURITIZATION:

At June 30, 2024, CONSOL Energy and certain of its U.S. subsidiaries are parties to a trade accounts receivable securitization facility with financial institutions for the sale on a continuous basis of eligible trade accounts receivable. In July 2022, the securitization facility was amended to, among other things, extend the maturity date to July 29, 2025.

Pursuant to the securitization facility, CONSOL Thermal Holdings LLC, an indirect, wholly-owned subsidiary of the Company, sells trade receivables to CONSOL Pennsylvania Coal Company LLC, a wholly-owned subsidiary of the Company. CONSOL Marine Terminals LLC, a wholly-owned subsidiary of the Company, and CONSOL Pennsylvania Coal Company LLC sell and/or contribute trade receivables (including receivables sold to CONSOL Pennsylvania Coal Company LLC by CONSOL Thermal Holdings LLC) to CONSOL Funding LLC, a wholly-owned subsidiary of the Company (the “SPV”). The SPV, in turn, pledges its interests in the receivables to PNC Bank, N.A., which either makes loans or issues letters of credit on behalf of the SPV. The maximum amount of advances and letters of credit outstanding under the securitization facility may not exceed $100,000.

Loans under the securitization facility accrue interest at a reserve-adjusted market index rate equal to the applicable term Secured Overnight Financing Rate (“SOFR”). Loans and letters of credit under the securitization facility also accrue a program fee and a letter of credit participation fee, respectively, ranging from 2.00% to 2.50% per annum depending on the total net leverage ratio of CONSOL Energy. In addition, the SPV paid certain structuring fees to PNC Capital Markets LLC and pays other customary fees to the lenders, including a fee on unused commitments equal to 0.60% per annum.

At June 30, 2024, the Company's eligible accounts receivable yielded $53,510 of borrowing capacity. At June 30, 2024, the facility had no outstanding borrowings and $50,831 of letters of credit outstanding, leaving available borrowing capacity of $2,679. At December 31, 2023, the Company's eligible accounts receivable yielded $72,125 of borrowing capacity. At December 31, 2023, the facility had no outstanding borrowings and $72,087 of letters of credit outstanding, leaving available borrowing capacity of $38. Costs associated with the receivables facility totaled $347 and $712 for the three and six months ended June 30, 2024, respectively, and $324 and $737 for the three and six months ended June 30, 2023, respectively. The Company has not derecognized any receivables due to its continued involvement in the collections efforts.

Coal reserves are either owned in fee or controlled by lease. The duration of the leases vary; however, the lease terms are generally extended automatically to the exhaustion of economically recoverable reserves, as long as active mining continues. Coal interests held by lease provide the same rights as fee ownership for mineral extraction and are legally considered real property interests.

As of June 30, 2024 and December 31, 2023, property, plant and equipment includes gross assets under finance leases of $32,418 and $44,622, respectively. Accumulated amortization for finance leases was $24,716 and $31,873 at June 30, 2024 and December 31, 2023, respectively. Amortization expense for assets under finance leases approximated $2,525 and $6,944 for the three months ended June 30, 2024 and 2023, respectively, and $5,542 and $13,845 for the six months ended June 30, 2024 and 2023, respectively, and is included in Depreciation, Depletion and Amortization in the accompanying Consolidated Statements of Income.

Revolving Credit Facility

In November 2017, CONSOL Energy entered into a revolving credit facility with PNC Bank, N.A. (the “Revolving Credit Facility”). The Revolving Credit Facility has been amended several times, the most recent of which occurred in June 2023. This amendment increased the available revolving commitments from $260,000 to $355,000 and provides for the Company's ability to increase the revolving commitments or issue term loans in an additional amount not to exceed $45,000 and up to an aggregate total amount of $400,000. The maturity date of the Revolving Credit Facility is July 18, 2026.

Borrowings under the Company's Revolving Credit Facility bear interest at a floating rate that is, at the Company's option, either (i) SOFR plus the applicable SOFR adjustment (as defined therein) depending on the applicable interest period plus an applicable margin or (ii) an alternate base rate plus an applicable margin. The applicable margin for the Revolving Credit Facility depends on the Company's total net leverage ratio and this rate resets quarterly. Obligations under the Revolving Credit Facility are guaranteed by (i) all owners of the PAMC held by the Company, (ii) any other members of the Company’s group that own any portion of the collateral securing the Revolving Credit Facility, and (iii) subject to certain customary exceptions and agreed materiality thresholds, all other existing or future direct or indirect wholly-owned restricted subsidiaries of the Company. The obligations are secured by, subject to certain exceptions (including a limitation of pledges of equity interests in certain subsidiaries and certain thresholds with respect to real property), a first-priority lien on (i) the Company’s interest in the PAMC, (ii) the equity interests in PA Mining Complex LP held by the Company, (iii) the CONSOL Marine Terminal, (iv) the Itmann Mining Complex and (v) the 1.3 billion tons of Greenfield Reserves and Resources.

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, dispositions, restricted payments and prepayments of junior indebtedness. The Revolving Credit Facility also includes covenants relating to (i) a maximum first lien gross leverage ratio, (ii) a maximum total net leverage ratio, and (iii) a minimum fixed charge coverage ratio. The maximum first lien gross leverage ratio is calculated as the ratio of Consolidated First Lien Debt to Consolidated EBITDA. Consolidated EBITDA, as used in the covenant calculation, excludes non-cash compensation expenses, non-recurring transaction expenses, extraordinary gains and losses, gains and losses on discontinued operations and gains and losses on debt extinguishment. The maximum total net leverage ratio is calculated as the ratio of Consolidated Indebtedness, minus Cash on Hand, to Consolidated EBITDA. The minimum fixed charge coverage ratio is calculated as the ratio of Consolidated EBITDA to Consolidated Fixed Charges. Consolidated Fixed Charges, as used in the covenant calculation, include cash interest payments, cash payments for income taxes, scheduled debt repayments, Maintenance Capital Expenditures and cash payments related to legacy employee liabilities to the extent in excess of amounts accrued in the calculation of Consolidated EBITDA. Under the Revolving Credit Facility, the maximum first lien gross leverage ratio shall be 1.50 to 1.00, the maximum total net leverage ratio shall be 2.50 to 1.00 and the minimum fixed charge coverage ratio shall be 1.10 to 1.00.

Table of Contents

The Company's first lien gross leverage ratio was 0.01 to 1.00 at June 30, 2024. The Company's total net leverage ratio was (0.15) to 1.00 at June 30, 2024.

At December 31, 2023, the Revolving Credit Facility had no borrowings outstanding and $111,186 of letters of credit outstanding, leaving $243,814 of unused capacity. From time to time, CONSOL Energy 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. CONSOL Energy sometimes uses letters of credit to satisfy these requirements and these letters of credit reduce the Company's borrowing facility capacity.

The SPV is not a guarantor of the Revolving Credit Facility, and the SPV holds the assets pledged to the lender in the securitization facility. The SPV had total assets of $141,231 and $147,918, comprised mainly of $140,904 and $147,612 trade receivables, net, at June 30, 2024 and December 31, 2023, respectively. Net income attributable to the SPV was $201 and $1,986 for the three months ended June 30, 2024 and 2023, respectively, and $247 and $4,608 for the six months ended June 30, 2024 and 2023, respectively, which primarily reflected intercompany fees related to purchasing the receivables, which are eliminated in the Consolidated Financial Statements contained within this Quarterly Report on Form 10-Q. During the six months ended June 30, 2024 and 2023, there were no borrowings or payments under the accounts receivable securitization facility. See Note 9 - Accounts Receivable Securitization for additional information.

PEDFA Bonds

In April 2021, CONSOL Energy borrowed the proceeds received from the sale of tax-exempt bonds issued by the Pennsylvania Economic Development Financing Authority (“PEDFA”) in an aggregate principal amount of $75,000 (the “PEDFA Bonds”). The PEDFA Bonds bear interest at a fixed rate of 9.00% for an initial term of seven years. The PEDFA Bonds mature on April 1, 2051 but are subject to mandatory purchase by the Company on April 13, 2028, at the expiration of the initial term rate period. The PEDFA Bonds were issued pursuant to an indenture (the “PEDFA Indenture”) dated as of April 1, 2021, by and between PEDFA and Wilmington Trust, N.A., a national banking association, as trustee (the “PEDFA Notes Trustee”). PEDFA made a loan of the proceeds of the PEDFA Bonds to the Company pursuant to a Loan Agreement (the “Loan Agreement”) dated as of April 1, 2021 between PEDFA and the Company. Under the terms of the Loan Agreement, the Company agreed to make all payments of principal, interest and other amounts at any time due on the PEDFA Bonds or under the PEDFA Indenture. PEDFA assigned its rights as lender under the Loan Agreement, excluding certain reserved rights, to the PEDFA Notes Trustee. Certain subsidiaries of the Company (the “PEDFA Notes Guarantors”) executed a Guaranty Agreement (the “Guaranty”) dated as of April 1, 2021 in favor of the PEDFA Notes Trustee, guarantying the obligations of the Company under the Loan Agreement to pay the PEDFA Bonds when and as due. The obligations of the Company under the Loan Agreement and of the PEDFA Notes Guarantors under the Guaranty are secured by second priority liens on substantially all of the assets of the Company and the PEDFA Notes Guarantors. The Loan Agreement and Guaranty incorporate by reference covenants in the Indenture, dated as of November 13, 2017 by and between the Company and UMB Bank, N.A., a national banking association, as trustee and collateral trustee, under which the 11.00% Senior Secured Second Lien Notes due 2025 (the “Second Lien Notes”) were issued, including covenants that limited the ability of the Company and certain subsidiaries of the Company, as guarantors, to (i) incur, assume or guarantee additional indebtedness or issue preferred stock; (ii) create liens to secure indebtedness; (iii) declare or pay dividends on the Company’s common stock, redeem stock or make other distributions to the Company’s stockholders; (iv) make investments; (v) pay or make dividends, loans or other asset transfers from the Company’s restricted subsidiaries; (vi) merge or consolidate, or sell, transfer, lease or dispose of substantially all of the Company’s assets; (vii) sell or otherwise dispose of certain assets, including equity interests in subsidiaries; (viii) enter into transactions with affiliates; and (ix) create unrestricted subsidiaries. These covenants were subject to important exceptions and qualifications.

The Company started a capital construction project on the PAMC coarse refuse disposal area in 2017, which is now funded, in part, by the proceeds from the PEDFA Bonds. The Company expects to expend these funds as qualified work is completed. The Company utilized restricted cash in the amount of $4,006 and $7,041 during the three and six months ended June 30, 2024, respectively, and $4,627 and $7,871 during the three and six months ended June 30, 2023, respectively, for qualified expenses. Additionally, the Company had $5,402 and $12,177 in restricted cash at June 30, 2024 and December 31, 2023, respectively, associated with this financing that will be used to fund future spending on the coarse refuse disposal area.

NOTE 13—COMMITMENTS AND CONTINGENT LIABILITIES:

The Company is subject to various lawsuits and claims with respect to such matters as personal injury, wrongful death, damage to property, exposure to hazardous substances, governmental regulations including environmental remediation, employment and contract disputes and other claims and actions arising out of the normal course of business. The Company accrues the estimated loss for these lawsuits and claims when the loss is probable and reasonably estimable. The Company’s estimated accruals related to these pending claims, individually and in the aggregate, are immaterial to the financial position, results of operations or cash flows of the Company as of June 30, 2024. It is possible that the aggregate loss in the future with respect to these lawsuits and claims could ultimately be material to the Company’s financial position, results of operations or cash flows; however, such amounts cannot be reasonably estimated. The amount claimed against the Company as of June 30, 2024 is disclosed below when an amount is expressly stated in the lawsuit or claim, which is not often the case.

Fitzwater Litigation: Three nonunion retired coal miners have sued Fola Coal Company LLC, Consolidation Coal Company (“CCC”) and CONSOL of Kentucky Inc. (“COK”) (as well as the Company's former parent) in the U.S. District Court for the Southern District of West Virginia alleging ERISA violations in the termination of retiree health care benefits. The Plaintiffs contend they relied to their detriment on oral statements and promises of “lifetime health benefits” allegedly made by various members of management during Plaintiffs’ employment and that they were allegedly denied access to Summary Plan Documents that clearly reserved to the Company the right to modify or terminate the Retiree Health and Welfare Plan subject to Plaintiffs’ claims. Pursuant to Plaintiffs’ amended complaint filed on April 24, 2017, Plaintiffs request that retiree health benefits be reinstated and seek to represent a class of all nonunion retirees who were associated with AMVEST and COK areas of operation. On October 15, 2019, Plaintiffs’ supplemental motion for class certification was denied on all counts. On July 15, 2020, Plaintiffs filed an interlocutory appeal with the Fourth Circuit Court of Appeals on the Order denying class certification. The Fourth Circuit denied Plaintiffs' appeal on August 14, 2020. On October 1, 2020, the District Court entered a pretrial order setting the trial date, which was held in February 2021. No ruling has been issued by the judge. The Company believes it has a meritorious defense and intends to vigorously defend this suit. With respect to this lawsuit, while a loss is reasonably possible, it is not probable and, as a result, no accrual has been recorded.

Casey Litigation: A class action lawsuit was filed on August 23, 2017 on behalf of two nonunion retired coal miners against CCC, COK, CONSOL Buchanan Mining Co., LLC and Kurt Salvatori, the Company's Chief Administrative Officer, in the U.S. District Court for the Southern District of West Virginia alleging ERISA violations in the termination of retiree health care benefits. Filed by the same lawyers who filed the Fitzwater litigation, and raising nearly identical claims, the Plaintiffs contend they relied to their detriment on oral promises of “lifetime health benefits” allegedly made by various members of management during Plaintiffs’ employment and that they were not provided with copies of Summary Plan Documents clearly reserving to the Company the right to modify or terminate the Retiree Health and Welfare Plan. Plaintiffs request that retiree health benefits be reinstated for them and their dependents and seek to represent a class of all nonunion retirees of any subsidiary of the Company's former parent that operated or employed individuals in McDowell or Mercer Counties, West Virginia, or Buchanan or Tazewell Counties, Virginia whose retiree welfare benefits were terminated. On December 1, 2017, the trial court judge in Fitzwater signed an order to consolidate Fitzwater with Casey. The Casey complaint was amended on March 1, 2018 to add new plaintiffs, add defendant CONSOL Pennsylvania Coal Company LLC and eliminate defendant CONSOL Buchanan Mining Co., LLC in an attempt to expand the class of retirees. On October 15, 2019, Plaintiffs’ supplemental motion for class certification was denied on all counts. On July 15, 2020, Plaintiffs filed an interlocutory appeal with the Fourth Circuit Court of Appeals on the Order denying class certification. The Fourth Circuit denied Plaintiffs' appeal on August 14, 2020. On October 1, 2020, the District Court entered a pretrial order setting the trial date, which was held in February 2021. No ruling has been issued by the judge. The Company believes it has a meritorious defense and intends to vigorously defend this suit. With respect to this lawsuit, while a loss is reasonably possible, it is not probable and, as a result, no accrual has been recorded.

United Mine Workers of America 1992 Benefit Plan Litigation: In 2013, Murray Energy and its subsidiaries (“Murray”) entered into a stock purchase agreement (the “Murray sale agreement”) with the Company's former parent pursuant to which Murray acquired the stock of CCC and certain subsidiaries and certain other assets and liabilities. At the time of sale, the liabilities included certain retiree medical liabilities under the Coal Industry Retiree Health Benefit Act of 1992 (“Coal Act”) and certain federal black lung liabilities under the Black Lung Benefits Act (“BLBA”). Based upon information available, the Company estimates that the annual servicing costs of these liabilities are approximately $10 million to $20 million per year for the next ten years. The annual servicing cost would decline each year since the beneficiaries of the Coal Act consist principally of miners who retired prior to 1994. Murray filed for Chapter 11 bankruptcy in October 2019. As part of the bankruptcy proceedings, Murray unilaterally entered into a settlement with the United Mine Workers of America 1992 Benefit Plan (the “1992 Benefit Plan”) to transfer retirees in the Murray Energy Section 9711 Plan to the 1992 Benefit Plan. This was approved by the bankruptcy court on April 30, 2020. On May 2,

Table of Contents

2020, the 1992 Benefit Plan filed an action in the United States District Court for the District of Columbia asking the court to make a determination whether the Company's former parent or the Company has any continuing retiree medical liabilities under the Coal Act (the “1992 Plan Lawsuit”). The Murray sale agreement includes indemnification by Murray with respect to the Coal Act and BLBA liabilities. In addition, the Company had agreed to indemnify its former parent relative to certain pre-separation liabilities. As of September 16, 2020, the Company entered into a settlement agreement with Murray and withdrew its claims in bankruptcy. On September 11, 2020, the Defendants in the 1992 Plan Lawsuit filed a Motion to Dismiss Plaintiffs' Second Amended Complaint which was denied by the Court on March 29, 2022. The Company will continue to vigorously defend any claims that attempt to transfer any of such liabilities directly or indirectly to the Company, including raising all applicable defenses against the 1992 Benefit Plan’s suit. With respect to this lawsuit, while a loss is reasonably possible, it is not probable and, as a result, no accrual has been recorded.

United Mine Workers of America 1974 Pension Plan Litigation: On March 7, 2024, the Company's former parent filed a complaint (the “Indemnification Lawsuit”) in the Superior Court of the State of Delaware against the Company that stated that the Company's former parent had settled potential claims asserted by the United Mine Workers of America 1974 Pension Plan (“1974 Plan”) against the Company's former parent for a total settlement amount of $75,000 to be paid over a five year period, in exchange for a full release by the 1974 Plan of the Company's former parent, the Company and their affiliates. In the Indemnification Lawsuit, the Company's former parent is seeking (i) indemnification from the Company under the 2017 Separation and Distribution Agreement between the Company and its former parent for the $75,000 settlement plus the Company's former parent's alleged legal expenses related to its settlement with the 1974 Plan, (ii) the costs and expenses the Company's former parent incurs in connection with the Indemnification Lawsuit, (iii) pre- and post-judgment interest, (iv) punitive damages and (v) any other relief the court deems just and proper. On May 9, 2024, the Company's former parent filed a Motion for Summary Judgment while the Company filed a brief in opposition of the motion on June 27, 2024, with briefing concluding on July 19, 2024. The Court has not yet ruled on this motion. The Company does not believe that it has any obligations to indemnify its former parent under the Separation and Distribution Agreement with respect to its former parent's settlement with the 1974 Plan and intends to vigorously defend itself against all claims asserted against it in the Indemnification Lawsuit. With respect to this lawsuit, while a loss is reasonably possible, it is not probable and, as a result, no accrual has been recorded.

The Company and various subsidiaries are defendants in certain other legal proceedings. In the opinion of management, based upon an investigation of these matters and discussion with legal counsel, the ultimate outcome of such other legal proceedings, individually and in the aggregate, is not expected to have a material adverse effect on the Company’s financial position, results of operations or liquidity.

The following is a summary, as of June 30, 2024, of the financial guarantees, unconditional purchase obligations and letters of credit to certain third parties. Employee-related financial guarantees have primarily been provided to support the 1992 Benefit Plan and federal black lung and various state workers' compensation self-insurance programs. Environmental financial guarantees have primarily been provided to support various performance bonds related to reclamation and other environmental issues. Other financial guarantees have been extended to support sales contracts, insurance policies, surety indemnity agreements, legal matters, full and timely payments of mining equipment leases, and various other items necessary in the normal course of business. These amounts represent the maximum potential of total future payments that the Company could be required to make under these instruments. Certain letters of credit included in the table below were issued against other commitments included in this table. These amounts have not been reduced for potential recoveries under recourse or collateralization provisions. Generally, recoveries under reclamation bonds would be limited to the extent of the work performed at the time of the default. No amounts related to these commitments are recorded as liabilities in the financial statements. The Company's management believes that these commitments will not have a material adverse effect on the Company's financial condition.

The Company regularly evaluates the likelihood of default for all guarantees based on an expected loss analysis and records the fair value, if any, of its guarantees as an obligation in the Consolidated Financial Statements.

NOTE 14—FAIR VALUE OF FINANCIAL INSTRUMENTS:

CONSOL Energy determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources (including SOFR-based discount rates and U.S. Treasury-based rates), while unobservable inputs reflect the Company’s own assumptions of what market participants would use.

The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below.

Level One - Quoted prices for identical instruments in active markets. The Company's Level 1 assets include marketable debt securities, primarily highly liquid U.S. Treasury securities.

Level Two - The fair value of the assets and liabilities included in Level 2 are based on standard industry income approach models that use significant observable inputs, including SOFR-based discount rates and U.S. Treasury-based rates.

Level Three - Unobservable inputs significant to the fair value measurement supported by little or no market activity.

In those cases when the inputs used to measure fair value meet the definition of more than one level of the fair value hierarchy, the lowest level input that is significant to the fair value measurement in its totality determines the applicable level in the fair value hierarchy.

The financial instruments measured at fair value on a recurring basis are summarized below:


	Fair Value Measurements at						Fair Value Measurements at
	June 30, 2024						December 31, 2023
Description	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3
U.S. Treasury Securities	$	83,344	$	—	$	—	$	81,932	$	—	$	—

The following methods and assumptions were used to estimate the fair value for which the fair value option was not elected:

Table of Contents

Long-term debt: The fair value of long-term debt is measured using unadjusted quoted market prices or estimated using discounted cash flow analyses. The discounted cash flow analyses are based on current market rates for instruments with similar cash flows.

The carrying amounts and fair values of financial instruments for which the fair value option was not elected are as follows:


	June 30, 2024				December 31, 2023
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-Term Debt (Excluding Debt Issuance Costs)	$	184,696	$	198,866	$	185,206	$	199,591

Certain of the Company’s debt is actively traded on a public market and, as a result, constitutes Level 1 fair value measurements. The portion of the Company’s debt obligations that is not actively traded is valued through reference to the applicable underlying benchmark rate and, as a result, constitutes Level 2 fair value measurements.

NOTE 15—SEGMENT INFORMATION:

The Company reports segment information based on the “management” approach. The management approach designates the internal reporting used by management to make decisions on and assess performance of the Company’s reportable segments. CONSOL Energy presently consists of two reportable segments, the PAMC and the CONSOL Marine Terminal. The PAMC includes the Bailey Mine, the Enlow Fork Mine, the Harvey Mine and a centralized preparation plant. The PAMC segment’s principal activities include the mining, preparation and marketing of bituminous coal, sold primarily to industrial end-users, power generators and metallurgical end-users. The CONSOL Marine Terminal provides coal export terminal services through the Port of Baltimore. General and administrative costs are allocated to the Company’s segments based on a percentage of resources utilized, a percentage of total revenue and a percentage of total projected capital expenditures. CONSOL Energy’s Other segment includes revenue and expenses from various corporate and diversified business activities that are not allocated to the PAMC or the CONSOL Marine Terminal segments. The diversified business activities currently include the Itmann Mining Complex, carbon products and materials businesses led by CONSOL Innovations LLC, the Greenfield Reserves and Resources, closed mine activities, other income, gain on asset sales related to non-core assets, and gain/loss on debt extinguishment. Additionally, interest expense and income taxes, as well as various other non-operated activities, none of which are individually significant to the Company, are also reflected in CONSOL Energy's Other segment and are not allocated to the PAMC and CONSOL Marine Terminal segments.

The Company evaluates the performance of its segments utilizing Adjusted EBITDA and various productivity metrics. Adjusted EBITDA measures the operating performance of the Company's segments and is used to allocate resources to the Company's segments.

NOTE 16—STOCK AND DEBT REPURCHASES:

In December 2017, CONSOL Energy’s Board of Directors approved a program to repurchase, from time to time, the Company's outstanding shares of common stock or its Second Lien Notes. Since the program's inception, the Company's Board of Directors has subsequently amended the program several times. The most recent amendment occurred in April 2023, in which the aggregate limit of the Company's repurchase authority was raised to $1,000,000. The program terminates on December 31, 2024.

Under the terms of the program, CONSOL Energy is permitted to make repurchases in the open market, in privately negotiated transactions, accelerated repurchase programs or in structured share repurchase programs. CONSOL Energy is also authorized to enter into one or more 10b5-1 plans with respect to any of the repurchases. Any repurchases of common stock or notes are to be funded from available cash on hand or short-term borrowings. The program does not obligate CONSOL Energy to acquire any particular amount of its common stock or notes, and the program can be modified or suspended at any time at the Company’s discretion. The program is conducted in compliance with applicable legal requirements imposed by any credit agreement, receivables purchase agreement or indenture.

During the six months ended June 30, 2024 and 2023, the Company did not make any open market repurchases of its Second Lien Notes in accordance with this program; all remaining outstanding Second Lien Notes were redeemed by the Company during the year ended December 31, 2023. During the six months ended June 30, 2024 and 2023, the Company repurchased and retired 747,351 and 2,432,543 shares of the Company's common stock at an average price of $89.49 and $58.69 per share, respectively.

Recent Developments

On March 26, 2024, a container ship struck a support column of the Francis Scott Key Bridge in Baltimore, Maryland causing it to collapse. The United States Coast Guard established a safety zone for all navigable waters of the Chesapeake Bay within a 2,000-yard radius around the Francis Scott Key Bridge. As a result, vessel access in and out of the CONSOL Marine Terminal, which is located in the Port of Baltimore, was suspended. During this time, our team worked diligently to minimize the disruption to our business and address direct and indirect impacts to the Company and its operations, including moving coal through an alternative port on the East Coast of the United States, accelerating domestic shipments and managing ongoing expenditures. Our inability to ship coal to our customers from the CONSOL Marine Terminal temporarily negatively impacted our business, financial condition and results of operations.

On May 20, 2024, after a successful refloat and removal of the container ship that collided with the Francis Scott Key Bridge, a limited access channel in the Chesapeake Bay was opened to commercial vessel traffic. That same day, the CONSOL Marine Terminal resumed coal shipments to international markets. The permanent 700-foot wide, 50-foot deep channel was fully restored and opened to normal operations on June 10, 2024. We do not anticipate any further impact to the Company and its operations in future quarters as a result of the Francis Scott Key Bridge collapse.

Our Business

We are a leading, low-cost producer of high-quality bituminous coal, focused on the extraction and preparation of coal in the Appalachian Basin due to our ability to efficiently produce and deliver large volumes of high-quality coal at competitive prices, the strategic location of our mines and the industry experience of our management team.

Our most significant tangible assets are the PAMC and the CONSOL Marine Terminal. Coal from the PAMC is valued because of its high energy content (as measured in Btu per pound), relatively low levels of sulfur and other impurities, and strong thermoplastic properties that enable it to be used in metallurgical, industrial and power generation applications. We take advantage of these desirable quality characteristics and our extensive logistical network, which is directly served by both the Norfolk Southern Corporation (“Norfolk Southern”) and CSX Transportation Inc. (“CSX”) railroads, coupled with the operational synergies afforded by the CONSOL Marine Terminal, to aggressively market our product to a broad base of diverse and strategically selected industrial and metallurgical end users globally. We also continue to support top-performing power plant customers in the eastern United States and abroad.

We are continuing to expand our presence in the metallurgical coal market through our Itmann Mining Complex in West Virginia. The Itmann Preparation Plant was constructed in 2022 and shipped its first train in October 2022. The plant includes a train loadout located on the Guyandotte Class I rail line, which can be served by both Norfolk Southern and CSX.

Our operations, including the PAMC and the CONSOL Marine Terminal, have consistently generated strong free cash flows. As of December 31, 2023, the PAMC controls 583.5 million tons of high-quality Pittsburgh seam reserves, enough to allow for an equivalent of more than 20 years of full-capacity production. As of December 31, 2023, the Itmann Mining Complex includes 28.4 million tons of recoverable coal reserves that are sufficient to support an equivalent of more than 30 years of full-capacity production, based on our current estimates. In addition, we own or control approximately 1.3 billion tons of Greenfield Reserves and Resources, portions of which are located in the Northern Appalachian Basin (“NAPP”), the Central Appalachian Basin (“CAPP”) and the Illinois Basin (“ILB”). Our vision is to maximize cash flow generation through the safe, compliant, and efficient operation of our core asset base, while maintaining a strong balance sheet and liquidity, returning capital through share buybacks and/or dividends, and, when prudent, allocating capital toward compelling growth and diversification opportunities.

Table of Contents

Our core businesses consist of our:

•Pennsylvania Mining Complex: The PAMC, which includes the Bailey Mine, the Enlow Fork Mine, the Harvey Mine and the Central Preparation Plant, has extensive high-quality coal reserves. We mine our reserves from the Pittsburgh No. 8 Coal Seam, which is a large contiguous formation of high-Btu coal that is ideal for high productivity, low-cost longwall mining operations. The design of the PAMC is optimized to produce large quantities of coal on a cost-efficient basis. We can sustain high production volumes at comparatively low operating costs due to, among other things, our technologically advanced longwall mining systems, logistics infrastructure and safety. All our mines at the PAMC utilize longwall mining, which is a highly automated underground mining technique that produces large volumes of coal at lower costs compared to other underground mining methods.

•CONSOL Marine Terminal: Through our subsidiary CONSOL Marine Terminals LLC, we provide coal export terminal services through the Port of Baltimore. The terminal can either store coal or load coal directly into vessels from rail cars. It is also the only major east coast United States coal terminal served by two Class I railroads, Norfolk Southern and CSX.

•Itmann Mining Complex: Construction of the Itmann No. 5 Mine, located in Wyoming County, West Virginia, began in the second half of 2019; development mining began in April 2020, but the pace of the project was intentionally slowed to minimize capital spending due to the uncertainties surrounding the COVID-19 pandemic. The coal preparation plant was commissioned during the third quarter of 2022 and shipped its first train in October 2022. The operation continued its ramp up progress in 2023 with a focus on mains development and increasing staffing levels, both of which are needed for the long-term viability of the mine. The Company anticipates approximately 900 thousand tons per year of high-quality, low-vol coking coal production from the Itmann No. 5 Mine once it achieves its full run rate, with an anticipated mine life of 30+ years. The preparation plant also includes a rail loadout and the capability for processing up to an additional 750 thousand to 1 million saleable tons annually from third parties and mining of our surrounding reserves. This additional processing revenue provides an avenue of growth for the Company.

These low-cost assets and the diverse markets they serve provide us opportunities to generate cash across a wide variety of demand and pricing scenarios. The three mines at the PAMC operate up to five longwalls, and the production from all three mines is processed at a single, centralized preparation plant, which is connected via conveyor belts to each mine. The Central Preparation Plant, which can clean and process up to 9,000 raw tons of coal per hour, provides economies of scale while also maintaining the ability to segregate and blend coal based on quality. This infrastructure enables us to tailor our production levels and quality specifications to meet market demands. It also results in a highly productive, low-cost operation compared to other NAPP coal mines, with the PAMC averaging 7.50 tons of coal production per employee hour in 2022 and 2023. We believe our substantial capital investment in the PAMC will enable us to maintain high production volumes, low operating costs and a strong safety and environmental compliance record, which we believe are key to supporting stable financial performance and cash flows throughout business and commodity price cycles.

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) adjusted EBITDA, a non-GAAP financial measure; (ii) coal production, sales volumes and average coal revenue per ton; (iii) cost of coal sold, a non-GAAP financial measure; (iv) cash cost of coal sold, a non-GAAP financial measure; (v) average cash cost of coal sold per ton, an operating ratio derived from non-GAAP financial measures; and (vi) average cash margin per ton sold, an operating ratio derived from non-GAAP financial measures.

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. We believe cost of coal sold, cash cost of coal sold, average cash cost of coal sold per ton, and average cash margin per ton sold normalize the volatility contained within comparable GAAP measures by adjusting for certain non-operating or non-cash transactions. Each of these non-GAAP metrics are used as supplemental financial measures 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

Table of Contents

•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 operating and other costs, net income, 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 evaluate our cost of coal sold and cash cost of coal sold on an aggregate basis by segment, and our average cash cost of coal sold per ton on a per-ton basis. Cost of coal sold includes items such as direct operating costs, royalty and production taxes, direct administration costs, and depreciation, depletion and amortization costs on production assets. Cost of coal sold excludes any indirect costs and other costs not directly attributable to the production of coal. The cash cost of coal sold includes cost of coal sold less depreciation, depletion and amortization costs on production assets. We define average cash cost of coal sold per ton as cash cost of coal sold divided by tons sold. The GAAP measure most directly comparable to cost of coal sold, cash cost of coal sold and average cash cost of coal sold per ton is operating and other costs.

The following table presents a reconciliation for the PAMC segment of cash cost of coal sold, cost of coal sold and average cash cost of coal sold per ton to operating and other costs, the most directly comparable GAAP financial measure, on a historical basis, for each of the periods indicated (in thousands, except per ton information).

Revenues from Contracts with Customers

On a consolidated basis, coal revenue for the three months ended June 30, 2024 was $409 million, which consisted of $384 million from the Pennsylvania Mining Complex and $25 million from the Itmann Mining Complex. The $409 million of coal revenue was sold into the following markets: $219 million into power generation, $130 million into industrial, and $60 million into metallurgical. The Company had consolidated coal revenue of $541 million for the three months ended June 30, 2023, which consisted of $521 million from the Pennsylvania Mining Complex and $20 million from the Itmann Mining Complex. The $541 million of coal revenue was sold into the following markets: $241 million into power generation, $217 million into industrial, and $83 million into metallurgical. See “Operational Performance” for further information about segment results.

Table of Contents

The Company’s Terminal revenue consists of fees charged for coal loaded at the CONSOL Marine Terminal, which is located in the Port of Baltimore, Maryland, and provides access to international coal markets. Terminal revenues are generated from providing transloading services from rail to vessel or barge, temporary storage or stockpile facilities, as well as blending, weighing, and sampling. Terminal revenues were $12 million for the three months ended June 30, 2024, compared to $31 million for the three months ended June 30, 2023. See “Operational Performance - CONSOL Marine Terminal Analysis” for further information about segment results.

The Company recognizes freight revenue as the amount billed to customers for transportation costs incurred. This revenue is based on the weight of coal shipped, negotiated freight rates and method of transportation, primarily rail, used by the customers to which the Company contractually provides transportation services to move its coal from the mine to the ultimate sales point. Freight revenue is completely offset by freight expense. Freight revenue and freight expense were both $66 million for the three months ended June 30, 2024, compared to $82 million for the three months ended June 30, 2023.

Miscellaneous Other Income

Miscellaneous other income was $13 million for the three months ended June 30, 2024, compared to $7 million for the three months ended June 30, 2023. The change is due to the following items:


	Three Months Ended June 30,
	2024		2023		Variance
Interest Income	$	5	$	3	$	2
Royalty Income - Non-Operated Coal	5		2		3
Carbon Products and Materials	2		—		2

Other Income	1		2		(1)
Miscellaneous Other Income	$	13	$	7	$	6

Interest income increased primarily due to the Company's investment in marketable debt securities, comprised of highly liquid U.S. Treasury securities.

Royalty income increased as a result of additional leased coal volumes related to overriding royalty agreements or coal reserve leases between the Company and third-party operators.

Carbon products and materials revenue increased due to additional investments in coal-to-product businesses led by CONSOL Innovations LLC, our wholly-owned subsidiary.

Operating and Other Costs

On a consolidated basis, operating and other costs were $288 million for the three months ended June 30, 2024, compared to $277 million for the three months ended June 30, 2023. Operating and other costs increased in the period-to-period comparison due to the following items:


	Three Months Ended June 30,
	2024		2023		Variance
Operating Costs - PAMC	$	230	$	234	$	(4)
Operating Costs - Itmann Mining Complex	35		27		8
Operating Costs - Terminal	6		7		(1)
Employee-Related Legacy Liability Expense	6		3		3
Coal Reserve Holding Costs	2		3		(1)
Closed and Idle Mines	2		1		1

Other	7		2		5
Operating and Other Costs	$	288	$	277	$	11

Table of Contents

Operating costs for the Pennsylvania Mining Complex include items such as direct operating costs, royalties and production taxes and direct administration costs. In the period-to-period comparison, operating costs - PAMC decreased $4 million, primarily due to a reduced operating schedule during the first half of the current quarter as a result of the Francis Scott Key Bridge collapse, which limited our export capabilities. See “Operational Performance - PAMC Analysis” for further information on segment operating costs.

Operating costs for the Itmann Mining Complex primarily consist of costs related to produced tons sold and costs incurred to purchase third-party metallurgical coal to blend with Itmann coal. Operating costs - Itmann Mining Complex include items such as direct operating costs, royalties and production taxes and direct administration costs. The $8 million increase in operating costs - Itmann Mining Complex was primarily due to an increase in the volume of produced and purchased coal as the operations continued to ramp up toward full run-rate production.

Operating costs - Terminal primarily consist of costs related to throughput tons at the CONSOL Marine Terminal, which decreased $1 million in the period-to-period comparison. Despite reduced throughput activity due to restricted access to the CONSOL Marine Terminal during the first half of the current quarter, the team accelerated its annual summer maintenance during this time to allow for the ability to load and ship vessels during the railroads' and mining operations' planned summer shutdown period. See “Operational Performance - CONSOL Marine Terminal Analysis” for further information on segment operating costs.

Employee-related legacy liability expense increased $3 million in the period-to-period comparison primarily due to the impact of changes in actuarial assumptions made at the beginning of each year. See Note 3 - Components of Pension and Other Post-Employment Benefit (OPEB) Plans Net Periodic Benefit Costs and Note 4 - Components of Coal Workers' Pneumoconiosis (CWP) and Workers' Compensation Net Periodic Benefit Costs in the Notes to the Consolidated Financial Statements in Item 1 of this Form 10-Q for additional information.

Other costs consist of items that are not related to the Company's mining or terminal operations. Other costs increased $5 million in the three months ended June 30, 2024 compared to the three months ended June 30, 2023. The increase was primarily attributable to $2 million of additional costs related to new investments in businesses led by CONSOL Innovations LLC, particularly the production of composite tools used in the aerospace industry, as well as other expenses incurred in the current quarter across various categories, none of which were individually material.

Depreciation, Depletion and Amortization

On a consolidated basis, depreciation, depletion and amortization costs were $55 million for the three months ended June 30, 2024, compared to $65 million for the three months ended June 30, 2023. The $10 million decrease was primarily due to additional assets becoming fully-depreciated, lower units-of-production depreciation expense from reduced tonnage, and a decrease in the Company's asset retirement obligation expense in the period-to-period comparison.

General and Administrative Costs

On a consolidated basis, general and administrative costs were $21 million for the three months ended June 30, 2024, compared to $25 million for the three months ended June 30, 2023. The $4 million decrease in the period-to-period comparison was primarily related to decreased expense under the long-term incentive compensation plan incurred in the three months ended June 30, 2024 compared to the three months ended June 30, 2023, primarily due to fluctuations in the Company's share price during each of the respective periods.

Interest Expense

On a consolidated basis, interest expense, net of amounts capitalized, was $5 million for the three months ended June 30, 2024, compared to $7 million for the three months ended June 30, 2023. The $2 million decrease in the period-to-period comparison was primarily due to less debt outstanding, as the Company fully retired its Term Loan B and Second Lien Notes in 2023.

Operational Performance: Three Months Ended June 30, 2024 Compared with the Three Months Ended June 30, 2023

CONSOL Energy presently consists of two reportable segments, the PAMC and the CONSOL Marine Terminal. The PAMC includes the Bailey Mine, the Enlow Fork Mine, the Harvey Mine and a centralized preparation plant. The PAMC segment's principal activities include the mining, preparation and marketing of bituminous coal, sold primarily to industrial end-users, metallurgical end-users and power generators. The segment also includes general and administrative activities and interest expense, as well as various other activities assigned to the PAMC segment, but not included in the cost components on a per unit basis.

PAMC ANALYSIS:

Coal Production

The table below presents total tons produced (in thousands) from the Pennsylvania Mining Complex for the periods indicated:


	Three Months Ended June 30,
Mine	2024	2023	Variance
Bailey	2,358	2,783	(425)
Enlow Fork	2,114	2,324	(210)
Harvey	1,112	1,226	(114)
Total	5,584	6,333	(749)

Table of Contents

Coal production was 5.6 million tons for the three months ended June 30, 2024, compared to 6.3 million tons for the three months ended June 30, 2023. Vessel access to, and export capability from, the CONSOL Marine Terminal was restricted on March 26, 2024 after the Francis Scott Key Bridge collapsed. As a result, the operating schedules at the PAMC mines were reduced during the first half of the current quarter, which led to the decreased production in the period-to-period comparison.

Coal Operations

Adjusted EBITDA for the three months ended June 30, 2024 was $138 million, compared to $270 million for the three months ended June 30, 2023. The decrease was primarily attributable to a $14.44 decrease in average coal revenue per ton sold, as well as a 0.6 million decrease in tons sold and a $3.49 increase in the average cash cost of coal sold per ton. The decrease in average coal revenue per ton sold was primarily due to weaker API2 prices quarter-over-quarter, which put downward pressure on the Company's realizations in the second quarter of 2024, and higher incremental transportation costs. These transportation costs were incurred due to the Company's utilization of an alternative port because access to the CONSOL Marine Terminal was suspended as a result of the Francis Scott Key Bridge collapse. These downward pressures were partially offset by stronger PJM West day ahead power prices, specifically due to warmer-than-normal temperatures in the PJM region in June 2024. Given the reduced export capability as a result of the Francis Scott Key Bridge collapse that occurred on March 26, 2024, the PAMC placed 2.9 million tons of coal, or 51% of its total tons sold, into the export market in the three months ended June 30, 2024. Comparatively, in the three months ended June 30, 2023, the PAMC placed 4.3 million tons of coal, or 68% of its total tons sold, into the export market.

Cash cost of coal sold was $230 million for the three months ended June 30, 2024, compared to $234 million for the three months ended June 30, 2023. The decrease in the cash cost of coal sold was primarily due to the reduced operating schedule during the first half of the current quarter as a result of the Francis Scott Key Bridge collapse, which limited our export capabilities. The average cash cost of coal sold per ton increased in the period-to-period comparison due to lower sales tons to absorb fixed costs on a per ton basis, as well as ongoing inflationary pressures on supplies, maintenance costs and contractor labor costs compared to the prior-year period.

CONSOL MARINE TERMINAL ANALYSIS:

Vessel access to, and export capability from, the CONSOL Marine Terminal was restricted on March 26, 2024 after the Francis Scott Key Bridge collapsed. Management worked diligently to minimize the disruption to our business and address direct and indirect impacts to the Company and its operations, including moving coal through an alternative port on the East Coast of the United States, accelerating domestic shipments and managing ongoing expenditures. On May 20, 2024, a limited access channel in the Chesapeake Bay was opened to commercial vessel traffic and coal shipments to international markets resumed from the CONSOL Marine Terminal. The permanent 700-foot wide, 50-foot deep channel was fully restored and opened to normal operations on June 10, 2024.

As a result of the bridge collapse, throughput volumes and revenue from those volumes were interrupted until May 20, 2024. The Company used this downtime to perform several maintenance projects originally scheduled to occur during the summer shutdown period. Accordingly, adjusted EBITDA for the three months ended June 30, 2024 was $5 million, compared to $24 million for the three months ended June 30, 2023. Throughput volumes at the CONSOL Marine Terminal were 2.3 million tons for the three months ended June 30, 2024, compared to 5.4 million tons for the three months ended June 30, 2023. CONSOL Marine Terminal revenue was $12 million for the three months ended June 30, 2024, compared to $31 million for the three months ended June 30, 2023.

Revenues from Contracts with Customers

On a consolidated basis, coal revenue for the six months ended June 30, 2024 was $857 million, which consisted of $801 million from the Pennsylvania Mining Complex and $56 million from the Itmann Mining Complex. The $857 million of coal revenue was sold into the following markets: $444 million into power generation, $283 million into industrial, and $130 million into metallurgical. The Company had consolidated coal revenue of $1,125 million for the six months ended June 30, 2023, which consisted of $1,085 million from the Pennsylvania Mining Complex and $40 million from the Itmann Mining Complex. The $1,125 million of coal revenue was sold into the following markets: $541 million into power generation, $410 million into industrial, and $174 million into metallurgical. See “Operational Performance” for further information about segment results.

The Company’s Terminal revenue consists of fees charged for coal loaded at the CONSOL Marine Terminal, which is located in the Port of Baltimore, Maryland, and provides access to international coal markets. Terminal revenues are generated from providing transloading services from rail to vessel or barge, temporary storage or stockpile facilities, as well as blending, weighing, and sampling. Terminal revenues were $37 million for the six months ended June 30, 2024, compared to $58 million for the six months ended June 30, 2023. See “Operational Performance - CONSOL Marine Terminal Analysis” for further information about segment results.

The Company recognizes freight revenue as the amount billed to customers for transportation costs incurred. This revenue is based on the weight of coal shipped, negotiated freight rates and method of transportation, primarily rail, used by the customers to which the Company contractually provides transportation services to move its coal from the mine to the ultimate sales point. Freight revenue is completely offset by freight expense. Freight revenue and freight expense were both $135 million for the six months ended June 30, 2024, compared to $149 million for the six months ended June 30, 2023.

Miscellaneous Other Income

Miscellaneous other income was $30 million for the six months ended June 30, 2024, compared to $12 million for the six months ended June 30, 2023. The change is due to the following items:


	Six Months Ended June 30,
	2024		2023		Variance
Interest Income	$	9	$	5	$	4
Royalty Income - Non-Operated Coal	9		4		5
Carbon Products and Materials	5		—		5
Contract Buyouts	3		—		3
Other Income	4		3		1
Miscellaneous Other Income	$	30	$	12	$	18

Interest income increased primarily due to the Company's investment in marketable debt securities, comprised of highly liquid U.S. Treasury securities.

Table of Contents

Royalty income increased as a result of additional leased coal volumes related to overriding royalty agreements or coal reserve leases between the Company and third-party operators.

Carbon products and materials revenue increased due to additional investments in coal-to-product businesses led by CONSOL Innovations LLC, our wholly-owned subsidiary.

Contract buyout income was primarily the result of partial contract buyouts that involved negotiations with customers to reduce coal quantities that they otherwise were obligated to purchase under contracts in exchange for payment of certain fees to the Company and did not impact forward contract terms.

Operating and Other Costs

On a consolidated basis, operating and other costs were $581 million for the six months ended June 30, 2024, compared to $537 million for the six months ended June 30, 2023. Operating and other costs increased in the period-to-period comparison due to the following items:


	Six Months Ended June 30,
	2024		2023		Variance
Operating Costs - PAMC	$	473	$	456	$	17
Operating Costs - Itmann Mining Complex	70		50		20

Coal Reserve Holding Costs	3		5		(2)
Closed and Idle Mines	3		2		1

Other	8		5		3
Operating and Other Costs	$	581	$	537	$	44

Operating costs for the Pennsylvania Mining Complex include items such as direct operating costs, royalties and production taxes and direct administration costs. In the period-to-period comparison, operating costs - PAMC increased $17 million, primarily due to additional costs associated with ongoing inflationary pressures, partially offset by lower costs in the second quarter of 2024 as a result of the reduced operating schedule following the Francis Scott Key Bridge collapse. See “Operational Performance - PAMC Analysis” for further information on segment operating costs.

Operating costs for the Itmann Mining Complex primarily consist of costs related to produced tons sold and costs incurred to purchase third-party metallurgical coal to blend with Itmann coal. Operating costs - Itmann Mining Complex include items such as direct operating costs, royalties and production taxes and direct administration costs. The $20 million increase in operating costs - Itmann Mining Complex was primarily due to an increase in the volume of produced and purchased coal as the operations continued to ramp up toward full run-rate production.

Operating costs - Terminal primarily consist of costs related to throughput tons at the CONSOL Marine Terminal, and these costs remained consistent in the period-to-period comparison. Despite reduced throughput activity due to restricted access to the CONSOL Marine Terminal during the first half of the second quarter of 2024, the team accelerated its annual summer maintenance during this time to allow for the ability to load and ship vessels during the railroads' and mining operations' planned summer shutdown period. See “Operational Performance - CONSOL Marine Terminal Analysis” for further information on segment operating costs.

Employee-related legacy liability expense increased $5 million in the period-to-period comparison primarily due to the impact of changes in actuarial assumptions made at the beginning of each year. See Note 3 - Components of Pension and Other Post-Employment Benefit (OPEB) Plans Net Periodic Benefit Costs and Note 4 - Components of Coal Workers' Pneumoconiosis (CWP) and Workers' Compensation Net Periodic Benefit Costs in the Notes to the Consolidated Financial Statements in Item 1 of this Form 10-Q for additional information.

Other costs consist of items that are not related to the Company's mining or terminal operations. Other costs increased $3 million in the six months ended June 30, 2024 compared to the six months ended June 30, 2023. The increase was primarily attributable to $4 million of additional costs related to new investments in businesses led by CONSOL Innovations LLC, particularly the production of composite tools used in the aerospace industry, as well as other expenses incurred in both periods across various categories, none of which were individually material.

Depreciation, Depletion and Amortization

On a consolidated basis, depreciation, depletion and amortization costs were $112 million for the six months ended June 30, 2024, compared to $124 million for the six months ended June 30, 2023. The $12 million decrease was primarily due to additional assets becoming fully-depreciated, lower units-of-production depreciation expense from reduced tonnage, and a decrease in the Company's asset retirement obligation expense in the period-to-period comparison.

General and Administrative Costs

On a consolidated basis, general and administrative costs were $42 million for the six months ended June 30, 2024, compared to $42 million for the six months ended June 30, 2023.

Interest Expense

On a consolidated basis, interest expense, net of amounts capitalized, was $10 million for the six months ended June 30, 2024, compared to $17 million for the six months ended June 30, 2023. The $7 million decrease in the period-to-period comparison was primarily due to less debt outstanding, as the Company fully retired its Term Loan B and Second Lien Notes in 2023.

PAMC ANALYSIS:

Coal Production

The table below presents total tons produced (in thousands) from the Pennsylvania Mining Complex for the periods indicated:


	Six Months Ended June 30,
Mine	2024	2023	Variance
Bailey	5,122	6,056	(934)

Harvey	2,403	2,584	(181)
Total	12,085	13,370	(1,285)

Coal production was 12.1 million tons for the six months ended June 30, 2024, compared to 13.4 million tons for the six months ended June 30, 2023. The PAMC's coal production decreased in the period-to-period comparison. Vessel access to, and export capability from, the CONSOL Marine Terminal was restricted on March 26, 2024 after the Francis Scott Key Bridge collapsed. As a result, the operating schedules at the PAMC mines were reduced during the first half of the second quarter of 2024.

Coal Operations

Adjusted EBITDA for the six months ended June 30, 2024 was $308 million, compared to $601 million for the six months ended June 30, 2023. The decrease was primarily attributable to a $15.23 decrease in average coal revenue per ton sold, as well as a 1.3 million decrease in tons sold and a $5.11 increase in the average cash cost of coal sold per ton. The decrease in average coal revenue per ton sold was primarily due to weaker API2 and natural gas prices year-over-year, which put downward pressure on the Company's realizations in 2024, and higher incremental transportation costs. These transportation costs were incurred due to the Company's utilization of an alternative port because access to the CONSOL Marine Terminal was suspended as a result of the Francis Scott Key Bridge collapse. In addition, after a modest rebound in the fourth quarter of 2023, demand for the Company's product in the power generation markets was muted during the first quarter of 2024 due to mild winter weather which caused weaker commodity prices both domestically and globally. These downward pressures were partially offset by stronger PJM West day ahead power prices in the second quarter of 2024, specifically due to the warmer-than-normal temperatures in the PJM region in June 2024. Despite the reduced export capability as a result of the Francis Scott Key Bridge collapse that occurred on March 26, 2024, the PAMC placed 6.6 million tons of coal, or 55% of its total tons sold, into the export market in the six months ended June 30, 2024. Comparatively, in the six months ended June 30, 2023, the PAMC placed 8.2 million tons of coal, or 62% of its total tons sold, into the export market.

Cash cost of coal sold was $473 million for the six months ended June 30, 2024, compared to $456 million for the six months ended June 30, 2023. The increase in the cash cost of coal sold and average cash cost of coal sold per ton was primarily due to ongoing inflationary pressures on supplies, maintenance costs and contractor labor costs compared to the prior-year period, as well as lower sales tons to absorb fixed costs on a per ton basis in the period-to-period comparison.

CONSOL MARINE TERMINAL ANALYSIS:

As a result of the bridge collapse, throughput volumes and revenue from those volumes were interrupted until May 20, 2024. The Company used this downtime to perform several maintenance projects originally scheduled to occur during the summer shutdown period. Accordingly, adjusted EBITDA for the six months ended June 30, 2024 was $22 million, compared to $44 million for the six months ended June 30, 2023. Throughput volumes at the CONSOL Marine Terminal were 6.8 million tons for the six months ended June 30, 2024, compared to 9.9 million tons for the six months ended June 30, 2023. CONSOL Marine Terminal revenue was $37 million for the six months ended June 30, 2024, compared to $58 million for the six months ended June 30, 2023.

Liquidity and Capital Resources

CONSOL Energy's potential sources of liquidity include cash generated from operations, cash on hand, short-term investments of U.S. Treasury securities, borrowings under the revolving credit facility and securitization facility (which are discussed below), and, if necessary, the ability to issue additional equity or debt securities. The Company believes that cash generated from these sources, without needing to issue additional 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.

In 2023, the Company amended its revolving credit facility to achieve additional financial flexibility by increasing the capacity of the facility and easing certain restrictive covenants, specifically around investments and shareholder returns. These covenants were simplified to better align with the significantly improved credit profile of the business and are now leverage and liquidity-based moving forward. The Company was successful in securing incremental commitments in the amount of $95 million, which includes commitments from multiple new lenders to the facility and upsized commitments from 60% of existing lenders. The revolving credit facility now has a borrowing capacity of $355 million and provides for the Company's ability to increase the revolving commitments or issue term loans in an additional amount not to exceed $45 million and up to an aggregate total amount of $400 million.

During the six months ended June 30, 2024, the Company generated cash flows from operating activities of approximately $194 million and utilized a portion of operating cash flows to repurchase outstanding shares of the Company's common stock. Our total liquidity as of June 30, 2024 was comprised of the following:


(in millions)	June 30, 2024
Cash and Cash Equivalents	$	216
Short-Term Investments	83
	299
Securitization Facility - Current Availability	54
Revolving Credit Facility - Current Availability	355
Less: Letters of Credit Outstanding	(179)
Total Liquidity	$	529

Events that negatively impact our overall financial condition and liquidity could result in our inability to comply with our credit facility's financial covenants. This could limit our access to our credit facilities if we are unable to obtain waivers from our lenders or amend the credit facilities. Additionally, access to capital remains challenging for the Company's industry as a result of banking, institutional and investor environmental, social and governance (“ESG”) requirements and limitations, which tend to discourage investment in coal and other fossil fuel companies. However, the Company expects to maintain adequate liquidity through its operating cash flow, cash and cash equivalents on hand, and short-term investments, as well as its revolving credit facility and securitization facility, to fund its working capital needs and capital expenditures in the short-term and long-term.

Uncertainty in the financial markets brings additional potential risks to CONSOL Energy. These risks include a reduction of our ability to raise capital in the equity markets, less availability and higher costs of additional credit and potential counterparty defaults. Overall market disruptions, including as a result of recent or additional bank failures, rising interest rates and sustained high inflation, may impact the Company's collection of trade receivables. As a result, CONSOL Energy regularly monitors the creditworthiness of its customers and counterparties and manages credit exposure through payment terms, credit limits, prepayments and security.

Over the past few years, the insurance and surety markets have been increasingly challenging, particularly for coal companies. We have experienced rising premiums, reduced coverage and/or fewer providers willing to underwrite policies and surety bonds. Terms have generally become more unfavorable, including increases in the amount of collateral required to secure surety bonds. However, more recently, we have seen insurance rates 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.

CONSOL Energy 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 Consolidated Balance Sheet at June 30, 2024. The various multi-employer benefit plans are discussed in Note 17—Other Employee Benefit Plans in the Notes to the Consolidated Financial Statements in Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. CONSOL Energy's total contributions under the Coal Industry Retiree Health Benefit Act of 1992 were $2 million and $2 million for the six months ended June 30, 2024 and 2023, respectively. Based on available information at December 31, 2023, CONSOL Energy's aggregate obligation for the UMWA Combined Benefit Fund and 1992 Benefit Plan is estimated to be approximately $33 million. CONSOL Energy 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 which are not reflected on the Consolidated Balance Sheet at June 30, 2024. Management believes these items will expire without being funded. See Note 13—Commitments and Contingent Liabilities in the Notes to the Consolidated Financial Statements included in Item 1 of this Form 10-Q for additional details of the various financial guarantees that have been issued by CONSOL Energy.

Cash Flows (in millions)

Cash Provided by Operating Activities	$	194	$	476	$	(282)
Cash Used in Investing Activities	$	(96)	$	(174)	$	78
Cash Used in Financing Activities	$	(85)	$	(386)	$	301

Cash provided by operating activities decreased $282 million in the period-to-period comparison, primarily due to the overall decrease in earnings at the PAMC and the CONSOL Marine Terminal and other working capital changes that occurred throughout both periods. The decrease in PAMC and CONSOL Marine Terminal earnings was partially due to the decrease in average PAMC coal revenue per ton sold, as well as the financial impact of the Francis Scott Key Bridge collapse.

Cash used in investing activities decreased $78 million in the period-to-period comparison, primarily due to a net investment of approximately $100 million in U.S. Treasury securities during the six months ended June 30, 2023. Capital expenditures increased $22 million primarily due to additional equipment-related expenditures and rebuilds during the six months ended June 30, 2024. The Company's capital expenditures are set forth below.

Cash used in financing activities decreased $301 million in the period-to-period comparison primarily driven by a $148 million decrease in net payments on indebtedness. Payments totaling $139 million were made toward the Company's outstanding Term Loan B and Second Lien Notes during the six months ended June 30, 2023, which were fully paid off in the second quarter of 2023 and the third quarter of 2023, respectively. Additionally, $75 million in dividend payments were made during the six months ended June 30, 2023. Cash outflows related to CONSOL Energy share repurchases totaled $71 million in the six months ended June 30, 2024, compared to $141 million in the six months ended June 30, 2023.

Revolving Credit Facility

In November 2017, CONSOL Energy entered into a revolving credit facility with PNC Bank, N.A. (the “Revolving Credit Facility”). The Revolving Credit Facility has been amended several times, the most recent of which occurred in June 2023. This amendment increased the available revolving commitments from $260 million to $355 million and provides for the Company's ability to increase the revolving commitments or issue term loans in an additional amount not to exceed $45 million and up to an aggregate total amount of $400 million. The maturity date of the Revolving Credit Facility is July 18, 2026.

Borrowings under the Company's Revolving Credit Facility bear interest at a floating rate that is, at the Company's option, either (i) SOFR plus the applicable SOFR adjustment (as defined therein) depending on the applicable interest period plus an applicable margin or (ii) an alternate base rate plus an applicable margin. The applicable margin for the Revolving Credit Facility depends on the Company's total net leverage ratio and this rate resets quarterly. Obligations under the Revolving Credit Facility are guaranteed by (i) all owners of the PAMC held by the Company, (ii) any other members of the Company’s group that own any portion of the collateral securing the Revolving Credit Facility, and (iii) subject to certain customary exceptions and agreed materiality thresholds, all other existing or future direct or indirect wholly-owned restricted subsidiaries of the Company. The obligations are secured by, subject to certain exceptions (including a limitation of pledges of equity interests in certain subsidiaries and certain thresholds with respect to real property), a first-priority lien on (i) the Company’s interest in the Pennsylvania Mining Complex, (ii) the equity interests in PA Mining Complex LP held by the Company, (iii) the CONSOL Marine Terminal, (iv) the Itmann Mining Complex, and (v) the 1.3 billion tons of Greenfield Reserves and Resources.

The Revolving Credit Facility also includes financial covenants, including (i) a maximum first lien gross leverage ratio, (ii) a maximum total net leverage ratio, and (iii) a minimum fixed charge coverage ratio. The maximum first lien gross leverage ratio is calculated as the ratio of Consolidated First Lien Debt to Consolidated EBITDA. Consolidated EBITDA, as used in the covenant calculation, excludes non-cash compensation expenses, nonrecurring transaction expenses, extraordinary gains and losses, gains and losses on discontinued operations and gains and losses on debt extinguishment. The maximum total net leverage ratio is calculated as the ratio of Consolidated Indebtedness, minus Cash on Hand, to Consolidated EBITDA. The minimum fixed charge coverage ratio is calculated as the ratio of Consolidated EBITDA to Consolidated Fixed Charges. Consolidated Fixed Charges, as used in the covenant calculation, include cash interest payments, cash payments for income taxes, scheduled debt repayments, Maintenance Capital Expenditures and cash payments related to legacy employee liabilities to the extent in excess of amounts accrued in the calculation of Consolidated EBITDA. Under the Revolving Credit Facility, the maximum first lien gross leverage ratio shall be 1.50 to 1.00, the maximum total net leverage ratio shall be 2.50 to 1.00 and the minimum fixed charge coverage ratio shall be 1.10 to 1.00.

The Company's first lien gross leverage ratio was 0.01 to 1.00 at June 30, 2024. The Company's total net leverage ratio was (0.15) to 1.00 at June 30, 2024. The Company's fixed charge coverage ratio was 2.80 to 1.00 at June 30, 2024. Accordingly, the Company was in compliance with all of its financial covenants under the Revolving Credit Facility as of June 30, 2024.

The Revolving Credit Facility contains customary events of default, including with respect to a failure to make payments when due, cross-default and cross-judgment default and certain bankruptcy and insolvency events.

At June 30, 2024, there were no borrowings outstanding under the Revolving Credit Facility and the facility is currently only used for providing letters of credit, with $128 million of letters of credit outstanding, leaving $227 million of unused capacity. From time to time, CONSOL Energy 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. CONSOL Energy sometimes uses letters of credit to satisfy these requirements and these letters of credit reduce the Company's borrowing facility capacity.

Table of Contents

Securitization Facility

Loans under the securitization facility accrue interest at a reserve-adjusted market index rate equal to the applicable term SOFR rate. Loans and letters of credit under the securitization facility also accrue a program fee and a letter of credit participation fee, respectively, ranging from 2.00% to 2.50% per annum depending on the total net leverage ratio of CONSOL Energy. In addition, the SPV paid certain structuring fees to PNC Capital Markets LLC and pays other customary fees to the lenders, including a fee on unused commitments equal to 0.60% per annum.

The agreements comprising the securitization facility contain various customary representations and warranties, covenants and default provisions which provide for the termination and acceleration of the commitments and loans under the securitization facility 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. CONSOL Energy guarantees the performance of the obligations of CONSOL Thermal Holdings LLC, CONSOL Marine Terminals LLC and CONSOL Pennsylvania Coal Company LLC under the securitization, and will guarantee the obligations of any additional originators or successor servicer that may become party to the securitization. However, neither CONSOL Energy nor its affiliates will guarantee collectability of receivables or the creditworthiness of obligors thereunder.

At June 30, 2024, eligible accounts receivable yielded $54 million of borrowing capacity. At June 30, 2024, the facility had no outstanding borrowings and approximately $51 million of letters of credit outstanding, leaving $3 million of unused capacity. Costs associated with the receivables facility were less than $1 million for the three months ended June 30, 2024. The Company has not derecognized any receivables due to its continued involvement in the collections efforts.

Pennsylvania Economic Development Financing Authority Bonds

In April 2021, CONSOL Energy borrowed the proceeds received from the sale of tax-exempt bonds issued by PEDFA in an aggregate principal amount of $75 million (the “PEDFA Bonds”). The PEDFA Bonds bear interest at a fixed rate of 9.00% for an initial term of seven years. The PEDFA Bonds mature on April 1, 2051 but are subject to mandatory purchase by the Company on April 13, 2028, at the expiration of the initial term rate period. The PEDFA Bonds were issued pursuant to an indenture (the “PEDFA Indenture”) dated as of April 1, 2021, by and between PEDFA and Wilmington Trust, N.A., a national banking association, as trustee (the “PEDFA Notes Trustee”). PEDFA made a loan of the proceeds of the PEDFA Bonds to the Company pursuant to a Loan Agreement (the “Loan Agreement”) dated as of April 1, 2021 between PEDFA and the Company. Under the terms of the Loan Agreement, the Company agreed to make all payments of principal, interest and other amounts at any time due on the PEDFA Bonds or under the PEDFA Indenture. PEDFA assigned its rights as lender under the Loan Agreement, excluding certain reserved rights, to the PEDFA Notes Trustee. Certain subsidiaries of the Company (the “PEDFA Notes Guarantors”) executed a Guaranty Agreement (the “Guaranty”) dated as of April 1, 2021 in favor of the PEDFA Notes Trustee, guarantying the obligations of the Company under the Loan Agreement to pay the PEDFA Bonds when and as due. The obligations of the Company under the Loan Agreement and of the PEDFA Notes Guarantors under the Guaranty are secured by second priority liens on substantially all of the assets of the Company and the PEDFA Notes Guarantors. The Loan Agreement and Guaranty incorporate by reference covenants in the Indenture, dated as of November 13, 2017, by and between the Company and UMB Bank, N.A., a national banking association, as trustee and collateral trustee, under which the Second Lien Notes were issued, including covenants that limited the ability of the Company and certain subsidiaries of the Company, as guarantors, to (i) incur, assume or guarantee additional indebtedness or issue preferred stock; (ii) create liens to secure indebtedness; (iii) declare or pay dividends on the Company’s common stock, redeem stock or make other distributions to the Company’s stockholders; (iv) make investments; (v) pay or make dividends, loans or other asset transfers from the Company’s restricted subsidiaries; (vi) merge or consolidate, or sell, transfer, lease or dispose of substantially all of the Company’s assets; (vii)

sell or otherwise dispose of certain assets, including equity interests in subsidiaries; (viii) enter into transactions with affiliates; and (ix) create unrestricted subsidiaries. These covenants were subject to important exceptions and qualifications.

Material Cash Requirements

CONSOL Energy expects to make payments of $14 million on its long-term debt obligations, including interest, in the next 12 months. Refer to Note 13 – Long-Term Debt of our Annual Report on Form 10-K for the year ended December 31, 2023 for additional information concerning material cash requirements in future years.

CONSOL Energy expects to make payments of $10 million on its operating and finance lease obligations, including interest, in the next 12 months. Refer to Note 14 – Leases of our Annual Report on Form 10-K for the year ended December 31, 2023 for additional information concerning material cash requirements in future years.

CONSOL Energy expects to make payments of $49 million on its employee-related long-term liabilities in the next 12 months. Refer to Note 15 – Pension and Other Postretirement Benefit Plans and Note 16 – Coal Workers’ Pneumoconiosis and Workers’ Compensation of our Annual Report on Form 10-K for the year ended December 31, 2023 for additional information concerning material cash requirements in future years.

CONSOL Energy believes it will be able to satisfy these material requirements with cash generated from operations, cash on hand, short-term investments, borrowings under the revolving credit facility and securitization facility, and, if necessary, cash generated from its ability to issue additional equity or debt securities.

Debt

At June 30, 2024, CONSOL Energy had total long-term debt and finance lease obligations of $193 million outstanding, including the current portion of $6 million. This long-term debt consisted of:

•An aggregate principal amount of $103 million of industrial revenue bonds, which were issued to finance the CONSOL Marine Terminal, which bear interest at 5.75% per annum and mature in September 2025. Interest on the industrial revenue bonds is payable on March 1 and September 1 of each year. Payment of the principal and interest on the notes is guaranteed by CONSOL Energy.

•An aggregate principal amount of $75 million of PEDFA Bonds, which were issued to finance the ongoing expansion of the coal refuse disposal area at the Central Preparation Plant, which bear interest at 9.00% per annum for an initial term of seven years and mature in April 2051. Interest on the PEDFA Bonds is payable on February 1 and August 1 of each year.

•An aggregate principal amount of $8 million of finance leases with a weighted average interest rate of 6.96%.

•Advanced royalty commitments of $6 million with a weighted average interest rate of 8.80% per annum.

•An aggregate principal amount of $1 million of other debt arrangements.

At June 30, 2024, CONSOL Energy had no borrowings outstanding and approximately $128 million of letters of credit outstanding under the $355 million senior secured Revolving Credit Facility. At June 30, 2024, CONSOL Energy had no borrowings outstanding and approximately $51 million of letters of credit outstanding under the $100 million securitization facility.

Stock and Debt Repurchases

In December 2017, CONSOL Energy’s Board of Directors approved a program to repurchase, from time to time, the Company's outstanding shares of common stock or its Second Lien Notes. Since the program's inception, the Company's Board of Directors has subsequently amended the program several times. The most recent amendment occurred in April 2023, in which the aggregate limit of the Company's repurchase authority was raised to $1 billion. The program terminates on December 31, 2024.

Table of Contents

During the six months ended June 30, 2024, the Company repurchased and retired 747,351 shares of the Company's common stock at an average price of $89.49 per share.

Total Equity and Dividends

Total equity attributable to CONSOL Energy was $1,438 million at June 30, 2024 and $1,343 million at December 31, 2023. See the Consolidated Statements of Stockholders' Equity in Item 1 of this Form 10-Q for additional details.

The declaration and payment of dividends by CONSOL Energy is at the discretion of CONSOL Energy's Board of Directors, and no assurance can be given that CONSOL Energy will return to declaring and paying dividends in the future. The determination to pay dividends in the future will depend upon, among other things, general business conditions, CONSOL Energy's financial results, shareholder return priorities, contractual or legal restrictions regarding the payment of dividends and such other factors as the Board of Directors deems relevant. Certain of the Company's financing arrangements may limit CONSOL Energy's ability to pay dividends and repurchase stock based on certain covenants.

Critical Accounting Estimates

CONSOL Energy prepares its financial statements in accordance with accounting principles generally accepted in the United States. 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, 2023.

Forward-Looking Statements

Certain statements in this Quarterly Report on Form 10-Q are “forward-looking statements” within the meaning of the federal securities laws. With the exception of historical matters, the matters discussed in this Quarterly Report on Form 10-Q 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 which include those words are usually forward-looking statements. When we describe strategy that involves risks or uncertainties, we are making forward-looking statements. The forward-looking statements in this Quarterly Report on Form 10-Q speak only as of the date of this Quarterly Report on Form 10-Q; 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 our 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:

•deterioration in economic conditions (including continued inflation) or changes in consumption patterns of our customers may decrease demand for our products, impair our ability to collect customer receivables and impair our ability to access capital;

•volatility and wide fluctuation in coal prices based upon a number of factors beyond our control;

•the effects pandemics may have on our business and results of operations and on the global economy;

•an extended decline in the prices we receive for our coal affecting our operating results and cash flows;

•significant downtime of our equipment or inability to obtain equipment, parts or raw materials;

•decreases in the availability of, or increases in the price of, commodities or capital equipment used in our coal mining operations;

•our reliance on major customers, our ability to collect payment from our customers and uncertainty in connection with our customer contracts;

•our inability to acquire additional coal reserves or resources that are economically recoverable;

•the availability and reliability of transportation facilities and other systems that deliver our coal to market and fluctuations in transportation costs;

•a loss of our competitive position;

•foreign currency fluctuations that could adversely affect the competitiveness of our coal abroad;

•the risks related to the fact that a significant portion of our production is sold in international markets and our compliance with export control and anti-corruption laws;

Table of Contents

•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 out longwall equipment, railroad derailments, 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;

•the risks associated with operating primarily in a single geographic area;

•failure to obtain or renew surety bonds or insurance coverages on acceptable terms;

•the effects of coordinating our operations with oil and natural gas drillers and distributors operating on our land;

•our inability to obtain financing for capital expenditures on satisfactory terms;

•the effect of new or existing laws or regulations or tariffs and other trade measures;

•our inability to find suitable acquisition targets or integrating the operations of future acquisitions into our operations;

•obtaining, maintaining and renewing governmental permits and approvals for our coal operations;

•the effects of asset retirement obligations, employee-related long-term liabilities and certain other liabilities;

•the effects of global conflicts on commodity prices and supply chains;

•uncertainties in estimating our economically recoverable coal reserves;

•the outcomes of various legal proceedings, including those which are more fully described herein;

•defects in our chain of title for our undeveloped reserves or failure to acquire additional property to perfect our title to coal rights;

•the risk of our debt agreements, our debt and changes in interest rates affecting our operating results and cash flows;

•information theft, data corruption, operational disruption and/or financial loss resulting from a terrorist attack or cyber incident;

•the potential failure to retain and attract qualified personnel of the Company;

•failure to maintain effective internal controls over financial reporting;

•the effects of our securities being excluded from certain investment funds as a result of increased ESG practices;

•uncertainty with respect to the Company’s common stock, potential stock price volatility and future dilution;

•uncertainty regarding the timing and value of any dividends we may declare;

•uncertainty as to whether we will repurchase shares of our common stock or outstanding debt securities;

•inability of stockholders to bring legal action against us in any forum other than the state courts of Delaware; and

•other unforeseen factors.

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”). The Company disclaims any intention or obligation to update publicly any forward-looking statements, whether in response to new information, future events, or otherwise, except as required by applicable law.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's exposures to market risk have not materially changed since December 31, 2023. Please see these quantitative and qualitative disclosures about market risk in Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” of our Annual Report on Form 10-K for the year ended December 31, 2023.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

CONSOL Energy, under the supervision and with the participation of its management, including CONSOL Energy's principal executive officer and principal financial officer, evaluated the effectiveness of the Company's “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, CONSOL Energy's principal executive officer and principal financial officer have concluded that the Company's disclosure controls and procedures are effective as of June 30, 2024 to ensure that information required to be disclosed by CONSOL Energy in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and includes controls and procedures designed to ensure that information required to be disclosed by CONSOL Energy in such reports is accumulated and communicated to CONSOL Energy's management, including CONSOL Energy's principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Table of Contents

Changes in Internal Controls over Financial Reporting

During the fiscal quarter covered by this Quarterly Report on Form 10-Q, there were no changes in the Company's internal controls over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act, that materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.

It should be noted that any system of controls, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system will be met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events.

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Our operations are subject to a variety of risks and disputes normally incidental to our business. As a result, we may, at any given time, be a defendant in various legal proceedings and litigation arising in the ordinary course of business. However, we are not currently subject to any material litigation, except as disclosed in Note 13 - Commitments and Contingent Liabilities in the Notes to the Consolidated Financial Statements in Part 1, Item 1 of this Form 10-Q, incorporated herein by this reference.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this quarterly report, you should carefully consider the factors described in “Part 1 - Item 1A. Risk Factors” of CONSOL Energy's 2023 Form 10-K. These described risks are not the only risks the Company faces. Additional risks and uncertainties not currently known to CONSOL Energy or that the Company currently deems to be immaterial also may materially adversely affect CONSOL Energy's business, financial condition and/or operating results.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The following table sets forth repurchases of the Company's common stock during the three months ended June 30, 2024:


	(a)	(b)		(c)	(d)
Period	Total Number of Shares Purchased (1)	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Number (or Approximate Dollar Value) of Shares that May Yet be Purchased Under the Plans or Programs (000s omitted) (2)
April 1, 2024 - April 30, 2024	132,063	$	83.27	132,063	$	310,300	(3)
May 1, 2024 - May 31, 2024	—	$	—	—	$	310,300	(3)
June 1, 2024 - June 30, 2024	—	$	—	—	$	310,300	(3)

(1) In December 2017, CONSOL Energy's Board of Directors approved a program to repurchase, from time to time, the Company's outstanding shares of common stock or its 11.00% Senior Secured Second Lien Notes due 2025. Since the inception of the program, CONSOL Energy Inc.'s Board of Directors has amended the program on several separate occasions. As a result of such amendments, the Company may now repurchase up to $1 billion of its stock and debt until December 31, 2024. As of August 8, 2024, approximately $310 million remained available under the stock and debt repurchase program. The repurchases will be effected from time to time on the open market or in privately negotiated transactions or under a Rule 10b5-1 plan. The program does not obligate CONSOL Energy to acquire any particular amount of its common stock or notes, and the program can be modified or suspended at any time at the Company's discretion.

(2) Management cannot estimate the number of shares that will be repurchased because purchases are made based upon the Company's stock price, the Company's financial outlook and alternative investment options.

(3) In the three months ended June 30, 2024, CONSOL Energy deployed cash of $13 million to repurchase approximately $11 million of its common stock in the second quarter of 2024 and settle $2 million of common stock repurchased in the first quarter of 2024.

Table of Contents

Dividends

In the fiscal year ended December 31, 2022, the Company initiated an enhanced shareholder capital return program through repurchases of shares of common stock and the payment of dividends. The declaration and payment of dividends by CONSOL Energy is at the discretion of CONSOL Energy's Board of Directors, and no assurance can be given that CONSOL Energy will return to declaring and paying dividends in the future. The determination to pay dividends in the future will depend upon, among other things, general business conditions, CONSOL Energy's financial results, shareholder return priorities, contractual or legal restrictions regarding the payment of dividends and such other factors as the Board of Directors deems relevant. Certain of the Company's financing arrangements may limit CONSOL Energy's ability to pay dividends and repurchase stock based on certain covenants.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4. MINE SAFETY DISCLOSURES

The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K (17 CFR 229.104) is included in Exhibit 95 to this Quarterly Report on Form 10-Q.

Schedule A

NON-EMPLOYEE DIRECTOR ANNUAL EQUITY AWARD

TERMS AND CONDITIONS

1.Terms and Conditions: This grant of service-based restricted stock units is made under the CONSOL Energy Inc. Omnibus Performance Incentive Plan (the “Plan”), and is subject in all respects to the terms of the Plan. All terms of the Plan are hereby incorporated into these terms and conditions (the “Terms and Conditions”) by reference. In the event of a conflict between one or more provisions of these Terms and Conditions and one or more provisions of the Plan, the provisions of the Plan shall govern. Each capitalized term not defined herein has the meaning assigned to such term in the Plan.

2.Confirmation of Grant: Effective as of _______, 20__ (the “Award Date”), CONSOL Energy Inc. (the “Company”) granted the Non-Employee Director whose name is set forth in the notice of grant (the “Grantee”) time-based Restricted Stock Units with respect to a specified number of shares of Common Stock as set forth in the Grantee’s notice of grant (the “RSUs”) with an estimated value of $[XXXX], based on the closing price of the Company Common Stock on _______, 20__. By accepting the RSUs, the Grantee acknowledges and agrees that the RSUs are subject to the Terms and Conditions and the terms of the Plan.

3.Stockholder Rights:

a.Except as provided in Section 3(b) below, the Grantee will not have any stockholder rights or privileges (including voting rights) with respect to the shares of Common Stock subject to the RSUs until such shares of Common Stock vest and are actually issued and registered in the Grantee’s name in the Company’s books and records.

b.If the Company declares a cash dividend on its shares of Common Stock, on the payment date of the dividend, the Grantee shall be credited with dividend equivalents equal to the amount of such cash dividend per share of Common Stock multiplied by the number of shares of Common Stock subject to the RSUs. The dividend equivalents will be subject to the same terms regarding vesting and forfeiture as the RSUs and will be paid in cash at the times that the corresponding shares of Common Stock associated with the RSUs are delivered (or forfeited at the time that the RSUs are forfeited). The Grantee shall be responsible for any tax liability associated with any cash payments in accordance with Section 10 below.

4.Automatic Forfeiture: The RSUs (including any RSUs that have vested but not yet been settled) will automatically be forfeited and all rights of the Grantee to the RSUs shall terminate under any of the following circumstances:

a.The Grantee’s service with the Company as a Non-employee Director is terminated by the Company for Cause.

b.The Committee requires recoupment of the RSUs in accordance with any recoupment policy adopted or amended by the Company from time to time or in accordance with the Plan.

5.Transferability: The RSUs shall not be sold, transferred, assigned, pledged or otherwise encumbered or disposed.

6.Vesting: The RSUs shall vest in full on the first anniversary date of the Award Date; provided that the Grantee continues to serve as a Non-Employee Director with the Company through such date. In the event the Grantee ceases to be a Non-Employee Director for any reason before the first anniversary of the Award Date other than as described in Sections 4 and 7, a number of the RSUs (rounded up to the nearest whole number) awarded to the Grantee shall become vested on a pro rata basis equal to the total number of RSUs granted on the Award Date, multiplied by a fraction the numerator of which is equal to the number of full months that have elapsed from the Award Date and the denominator of which is 12, and any remaining portion of the RSUs shall be forfeited and, the vested RSUs shall be settled as described in Section 9 below.

7.Termination of Service: If, prior to the first anniversary of the Award Date, (i) the Grantee’s service with the Company is terminated by reason of death or Disability (as defined below), the RSUs shall become vested in full and settled as described in Section 9 below. For purposes of these Terms and Conditions “Disability” means permanently and totally disabled in accordance with Section 409A of the Internal Revenue Code.

8.Change in Control: In the event of a Change in Control prior to the first anniversary of the Award Date, the RSUs shall become vested in full and settled as described in Section 9 below; provided, however, in the event that, following a Change in Control in which the RSUs are assumed, the RSUs shall continue to vest based on the one-year vesting schedule.

9.Settlement: Any RSUs not previously forfeited shall be settled by delivery of one share of Common Stock for each RSU being settled. The RSUs shall be settled as soon as practicable after the applicable vesting date or deferral date, if deferral election was made by the Grantee, (including without limitation for this purpose vesting upon the Grantee’s termination of service as provided in Section 7 and 8), but in no event later than 60 days after the applicable vesting date. Notwithstanding the foregoing, to the extent that the RSUs are subject to Section 409A of the Internal Revenue Code, all such payments shall be made in compliance with the requirements of Section 409A of the Internal Revenue Code, including application of the six month settlement delay for any specified employee (as defined in Section 409A of the Internal Revenue Code) in the event of vesting as a result of a separation from service (as defined in Section 409A of the Internal Revenue Code).

10.Tax Withholding: The Grantee as a Non-Employee Director is solely responsible for the satisfaction of all taxes and penalties that may arise in connection with the RSUs, and as such the Company has no withholding obligation associated with the vested RSUs.

11.No Right to Continued Service: The Grantee understands and agrees that these Terms and Conditions do not impact the right of the Company or any of its affiliates retaining the Grantee to terminate or change the terms of the Grantee’s service with the Company.

12.Captions: Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of these Terms and Conditions.

13.Severability: In the event that any provision in these Terms and Conditions shall be held invalid or unenforceable for any reason, such provision shall be severable from, and such invalidity or unenforceability shall not be construed to have any effect on, the remaining provisions of these Terms and Conditions.

Exhibit 95

Mine Safety and Health Administration Safety Data

We believe that CONSOL Energy is one of the safest mining companies in the world. The Company has in place health and safety programs that include extensive employee training, accident prevention, workplace inspection, emergency response, accident investigation, regulatory compliance and program auditing. The objectives of our health and safety programs are to eliminate workplace incidents, comply with all mining-related regulations and provide support for both regulators and the industry to improve mine safety.

The operation of our mines is subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (Mine Act). MSHA inspects our mines on a regular basis and issues various citations, orders and violations when it believes a violation has occurred under the Mine Act. We present information below regarding certain mining safety and health violations, orders and citations, issued by MSHA and related assessments and legal actions and mine-related fatalities with respect to our coal mining operations. In evaluating this information, consideration should be given to factors such as: (i) the number of violations, orders and citations will vary depending on the size of the coal mine, (ii) the number of violations, orders and citations issued will vary from inspector to inspector and mine to mine, and (iii) violations, orders and citations can be contested and appealed, and in that process, are often reduced in severity and amount, and are sometimes dismissed.

The table below sets forth for the three months ended June 30, 2024, for each coal mine of CONSOL Energy and its subsidiaries, the total number of: (i) violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard under section 104 of the Mine Act for which the operator received a citation from MSHA; (ii) orders issued under section 104(b) of the Mine Act; (iii) citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under section 104(d) of the Mine Act; (iv) flagrant violations under section 110(b)(2) of the Mine Act; (v) imminent danger orders issued under section 107(a) of the Mine Act; (vi) the total dollar value of proposed assessments from MSHA (regardless of whether CONSOL Energy has challenged or appealed the assessment); (vii) the total number of mining-related fatalities; (viii) notices from MSHA of a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards under section 104(e) of the Mine Act; (ix) notices from MSHA regarding the potential to have a pattern of violations as referenced in (viii) above; and (x) pending legal actions before the Federal Mine Safety and Health Review Commission (as of June 30, 2024) involving such coal or other mine, as well as the aggregate number of legal actions instituted and the aggregate number of legal actions resolved during the reporting period.

The provision for income taxes for the three and six months ended June 30, 2023 of $37,574, or 18.3%, and $79,167, or 16.6%, respectively, of earnings before income taxes was based on the Company's annual estimated income tax rate adjusted for discrete items. The effective tax rate for the three and six months ended June 30, 2023 differed from the U.S. federal statutory rate of 21%, primarily due to the tax benefit for excess percentage depletion and foreign derived intangible income.

Receivables [Abstract]
Accounts Receivable Securitization	ACCOUNTS RECEIVABLE SECURITIZATION: At June 30, 2024, CONSOL Energy and certain of its U.S. subsidiaries are parties to a trade accounts receivable securitization facility with financial institutions for the sale on a continuous basis of eligible trade accounts receivable. In July 2022, the securitization facility was amended to, among other things, extend the maturity date to July 29, 2025. Pursuant to the securitization facility, CONSOL Thermal Holdings LLC, an indirect, wholly-owned subsidiary of the Company, sells trade receivables to CONSOL Pennsylvania Coal Company LLC, a wholly-owned subsidiary of the Company. CONSOL Marine Terminals LLC, a wholly-owned subsidiary of the Company, and CONSOL Pennsylvania Coal Company LLC sell and/or contribute trade receivables (including receivables sold to CONSOL Pennsylvania Coal Company LLC by CONSOL Thermal Holdings LLC) to CONSOL Funding LLC, a wholly-owned subsidiary of the Company (the “SPV”). The SPV, in turn, pledges its interests in the receivables to PNC Bank, N.A., which either makes loans or issues letters of credit on behalf of the SPV. The maximum amount of advances and letters of credit outstanding under the securitization facility may not exceed $100,000. Loans under the securitization facility accrue interest at a reserve-adjusted market index rate equal to the applicable term Secured Overnight Financing Rate (“SOFR”). Loans and letters of credit under the securitization facility also accrue a program fee and a letter of credit participation fee, respectively, ranging from 2.00% to 2.50% per annum depending on the total net leverage ratio of CONSOL Energy. In addition, the SPV paid certain structuring fees to PNC Capital Markets LLC and pays other customary fees to the lenders, including a fee on unused commitments equal to 0.60% per annum. At June 30, 2024, the Company's eligible accounts receivable yielded $53,510 of borrowing capacity. At June 30, 2024, the facility had no outstanding borrowings and $50,831 of letters of credit outstanding, leaving available borrowing capacity of $2,679. At December 31, 2023, the Company's eligible accounts receivable yielded $72,125 of borrowing capacity. At December 31, 2023, the facility had no outstanding borrowings and $72,087 of letters of credit outstanding, leaving available borrowing capacity of $38. Costs associated with the receivables facility totaled $347 and $712 for the three and six months ended June 30, 2024, respectively, and $324 and $737 for the three and six months ended June 30, 2023, respectively. The Company has not derecognized any receivables due to its continued involvement in the collections efforts.

Fair Value of Financial Instruments

FAIR VALUE OF FINANCIAL INSTRUMENTS:

The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below.

Level One - Quoted prices for identical instruments in active markets. The Company's Level 1 assets include marketable debt securities, primarily highly liquid U.S. Treasury securities.

Level Three - Unobservable inputs significant to the fair value measurement supported by little or no market activity.

The financial instruments measured at fair value on a recurring basis are summarized below:


	Fair Value Measurements at						Fair Value Measurements at

Stock and Debt Repurchases	6 Months Ended
Stock and Debt Repurchases	Jun. 30, 2024
Equity [Abstract]
Stock and Debt Repurchases	STOCK AND DEBT REPURCHASES: In December 2017, CONSOL Energy’s Board of Directors approved a program to repurchase, from time to time, the Company's outstanding shares of common stock or its Second Lien Notes. Since the program's inception, the Company's Board of Directors has subsequently amended the program several times. The most recent amendment occurred in April 2023, in which the aggregate limit of the Company's repurchase authority was raised to $1,000,000. The program terminates on December 31, 2024. Under the terms of the program, CONSOL Energy is permitted to make repurchases in the open market, in privately negotiated transactions, accelerated repurchase programs or in structured share repurchase programs. CONSOL Energy is also authorized to enter into one or more 10b5-1 plans with respect to any of the repurchases. Any repurchases of common stock or notes are to be funded from available cash on hand or short-term borrowings. The program does not obligate CONSOL Energy to acquire any particular amount of its common stock or notes, and the program can be modified or suspended at any time at the Company’s discretion. The program is conducted in compliance with applicable legal requirements imposed by any credit agreement, receivables purchase agreement or indenture. During the six months ended June 30, 2024 and 2023, the Company did not make any open market repurchases of its Second Lien Notes in accordance with this program; all remaining outstanding Second Lien Notes were redeemed by the Company during the year ended December 31, 2023. During the six months ended June 30, 2024 and 2023, the Company repurchased and retired 747,351 and 2,432,543 shares of the Company's common stock at an average price of $89.49 and $58.69 per share, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for future periods. The Consolidated Balance Sheet at December 31, 2023 has been derived from the Audited Consolidated Financial Statements at that date but does not include all disclosures required by GAAP. This Form 10-Q report should be read in conjunction with CONSOL Energy Inc.'s Annual Report on Form 10-K for the year ended December 31, 2023. All dollar amounts discussed in these Notes to Consolidated Financial Statements are in thousands of U.S. dollars, except for per share amounts, and unless otherwise indicated.
Basis of Consolidation	Basis of Consolidation The Consolidated Financial Statements include the accounts of CONSOL Energy Inc. and its wholly-owned and majority-owned and/or controlled subsidiaries. All significant intercompany transactions and accounts have been eliminated in consolidation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09 Income Taxes (Topic 740). The amendments in this update address investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation, (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than five percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate), (3) disclose the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes, (4) disclose the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received), (5) disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign, and (6) disclose income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. The amendments in this update are effective for annual periods beginning after December 15, 2024, and should be applied prospectively. Management is currently evaluating the impact of this guidance, but does not expect this update to have a material impact on the Company's financial statements. In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280). The amendments in this update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. Topic 280 requires a public entity to report a measure of segment profit or loss that the chief operating decision maker uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment items and amounts, such as depreciation, amortization, and depletion expense, to be disclosed under certain circumstances. The amendments in this update do not change or remove those disclosure requirements. The amendments in this update also do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 and should be applied retrospectively. Management is currently evaluating the impact of this guidance, but does not expect this update to have a material impact on the Company's financial statements. In August 2023, the FASB issued ASU 2023-05 - Business Combinations—Joint Venture Formations (Subtopic 805-60). The amendments in this update address the accounting for contributions made to a joint venture, upon formation, in a joint venture's separate financial statements. The objectives of the amendments are to (1) provide decision-useful information to investors and other allocators of capital in a joint venture's financial statements and (2) reduce diversity in practice. The amendments in this update do not amend the definition of a joint venture, the accounting by an equity method investor for its investment in a joint venture, or the accounting by a joint venture for contributions received after its formation. The amendments in this update are effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. Existing joint ventures may elect to apply the guidance retrospectively. Management is currently evaluating the impact of this guidance, but does not expect this update to have a material impact on the Company's financial statements.
Earnings per Share	Earnings per Share Basic earnings per share are computed by dividing net income by the weighted average number of shares outstanding during the reporting period. Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average number of shares outstanding is increased to include additional shares from restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities, as applicable, were used to acquire shares of common stock at the average market price during the reporting period.
