Item 1.01 Entry into a Material Definitive Agreement.

On August 20, 2024, Arch Resources, Inc., a Delaware corporation (“Arch”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with CONSOL Energy Inc., a Delaware corporation (“CONSOL”), and Mountain Range Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of CONSOL (“Merger Sub”).

The Merger Agreement provides for the combination of Arch and CONSOL in an all-stock merger of equals transaction upon the terms and subject to the conditions set forth in the Merger Agreement. The combined company will be renamed “Core Natural Resources, Inc.” and will be headquartered in Canonsburg, Pennsylvania, with its common stock trading on the New York Stock Exchange (“NYSE”). The board of directors of each of Arch and CONSOL have unanimously approved the Merger Agreement and the transactions contemplated thereby.

The Merger. Upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Arch (the “Merger”), with Arch continuing as the surviving corporation in the Merger and a direct, wholly owned subsidiary of CONSOL. At the effective time of the Merger (the “Effective Time”), each share of Class A common stock, par value $0.01 per share, and Class B common stock, par value $0.01 per share, of Arch (together, “Arch Common Stock”), issued and outstanding immediately prior to the Effective Time (other than certain excluded shares) will be converted automatically into the right to receive 1.326 shares of common stock, par value $0.01 per share, of CONSOL (“CONSOL Common Stock”) (such number of shares, the “Per-Share Merger Consideration”).

At the Effective Time, outstanding Arch restricted stock units (“RSUs”) that are vested immediately prior to the Effective Time (including RSUs that vest as a result of the Merger) will be settled in shares of CONSOL Common Stock, based on the number of shares of Arch Common Stock underlying the applicable RSU award and the Per-Share Merger Consideration, rounded to the nearest whole number of shares. The level of vesting for any Arch performance-based RSUs settled in connection with the Merger will be the greater of target level performance or Arch’s actual performance through the Effective Time.

Any outstanding Arch RSUs granted after the execution of the Merger Agreement that are not vested at the Effective Time will be converted at the Effective Time into a time-based RSU or performance-based RSU, as applicable, denominated in shares of CONSOL Common Stock, with the same terms and conditions as under the corresponding Arch RSU immediately prior to such conversion (each, a “New CONSOL RSU”). The number of shares of CONSOL Common Stock underlying the New CONSOL RSUs will be based on the number of shares of Arch Common Stock underlying the applicable Arch RSU award prior to the conversion and the Per-Share Merger Consideration, rounded to the nearest whole number of shares.

Post-Closing Governance. Arch and CONSOL have also agreed to certain governance-related matters. At the Effective Time, the combined company’s board of directors will have eight members, consisting of (a) four directors designated by Arch, which will include Paul Lang, Arch’s Chief Executive Officer, and Richard Navarre, Arch’s Chair of its board of directors, who will serve as Lead Independent Director on the combined company’s board of directors, and (b) four directors designated by CONSOL, which will include James Brock, CONSOL’s Chairman and Chief Executive Officer. In addition, at the Effective Time, Mr. Brock will be appointed to serve as the Executive Chair of the combined company’s board of directors, and Mr. Lang will be appointed to serve as the Chief Executive Officer of the combined company. The Merger Agreement further provides that, among other officer appointments, Mitesh Thakkar will be the President and Chief Financial Officer of the combined company. At the Effective Time, CONSOL will amend its bylaws in the form attached as an Annex to the Merger Agreement in order to provide, among other things, for supermajority director voting requirements in connection with the combined company’s board of directors’ ability to modify certain of the agreed-upon governance terms set forth in the Merger Agreement for a specified period of time following the Effective Time.

Closing Conditions. The closing of the Merger is subject to customary conditions, including: (i) approval by holders of Arch Common Stock of a proposal to adopt the Merger Agreement and by holders of CONSOL Common Stock of a proposal to approve the issuance of CONSOL Common Stock in the Merger and an amendment to CONSOL’s certificate of incorporation to increase the authorized shares of common stock thereunder; (ii) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; (iii) receipt of clearances, approvals and consents under certain applicable foreign regulatory laws; (iv) the effectiveness of a registration statement on Form S-4 that will be filed by CONSOL for the issuance of the shares of CONSOL Common Stock; (v) the authorization of the listing of the shares of CONSOL Common Stock on the NYSE to be issued in the Merger, subject only to official notice of issuance; and (vi) the representations and warranties of Arch and CONSOL being true and correct (subject to certain qualifications). The obligation of Arch to consummate the Merger is further conditioned upon the receipt of a customary tax opinion of counsel to Arch that the Merger should qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

Representations, Warranties and Covenants. The Merger Agreement contains customary representations and warranties of Arch and CONSOL relating to their respective businesses, financial statements and public filings, among other matters, in each case generally subject to customary qualifications. Additionally, the Merger Agreement provides for customary pre-closing covenants of each of Arch and CONSOL, including (i) to conduct its business in the ordinary course (subject to certain exceptions); (ii) to cooperate with respect to seeking regulatory approvals subject to specified limitations; (iii) to hold a meeting of its stockholders to obtain the requisite stockholder approvals contemplated by the Merger Agreement, as applicable; (iv) not to solicit proposals relating to alternative business combination transactions; and (v) subject to certain exceptions, not to enter into any discussion concerning, or provide confidential information in connection with, alternative business combination transactions.

Termination. The Merger Agreement contains provisions granting each of Arch and CONSOL the right to terminate the Merger Agreement under specified circumstances, including: (i) if the Merger is not completed by August 20, 2025 (which date may be extended to November 20, 2025 in certain circumstances); (ii) if either CONSOL’s or Arch’s stockholders fail to approve a required proposal in connection with the Merger; (iii) if a final nonappealable governmental order has been issued prohibiting the Merger; (iv) if the other party has breached its representations, warranties or covenants in the Merger Agreement, subject to certain conditions; or (v) if the other party’s board of directors has changed its recommendation in connection with the Merger. In the event of a termination of the Merger Agreement under certain specified circumstances, Arch or CONSOL, as applicable, would be required to pay the other party a termination fee equal to $82.0 million. In addition, if the Merger Agreement is terminated due to a failure of CONSOL’s stockholders or Arch’s stockholders to approve the applicable proposals, CONSOL or Arch, as applicable, will be required to reimburse the other party for its expenses incurred in connection with the transaction in an amount not to exceed $23.5 million.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to and qualified in its entirety by reference to the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and which is incorporated by reference herein.

The Merger Agreement has been included to provide security holders and investors with information regarding its terms. It is not intended to provide any other factual information about CONSOL, Arch or any other person. The representations, warranties and covenants contained in the Merger Agreement were made solely for purposes of the Merger Agreement and as of specific dates, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to security holders. Security holders and investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Arch or CONSOL. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in CONSOL’s or Arch’s public disclosures.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On August 20, 2024, Mr. Lang entered into a Waiver, Acknowledgment and Amendment, a copy of which is attached hereto as Exhibit 10.1 and which is incorporated by reference herein, pursuant to which (i) the Change in Control Agreement between Arch and Mr. Lang (the “Lang Agreement”) will be deemed amended to reflect Mr. Lang’s new role as Chief Executive Officer of the combined company, reporting to the Executive Chair and serving in this role at the combined company’s headquarters in Pittsburgh, Pennsylvania, following the Effective Time and (ii) Mr. Lang agrees that any change in his duties upon completion of the Merger will not constitute “Good Reason” for purposes of and as defined in the Lang Agreement, nor will his relocation to the Pittsburgh headquarters.
