On November 2, 2025, SM Energy Company, a Delaware corporation (the “Company” or “SM Energy”), Cars Merger Sub, Inc., a Delaware corporation and direct wholly owned subsidiary of SM Energy (“Merger Sub”), and Civitas Resources, Inc., a Delaware corporation (“Civitas”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Upon the terms and subject to the conditions set forth in the Merger Agreement, (i) Merger Sub will merge with and into Civitas, with Civitas surviving as a wholly owned subsidiary of SM Energy (the “First Company Merger”), and (ii) immediately following the First Company Merger, Civitas as the surviving corporation (the “First Surviving Corporation”) will merge with and into SM Energy, with SM Energy continuing as the surviving corporation (the “Second Company Merger” and, together with the First Company Merger, the “Mergers”). The First Company Merger will become effective at a time agreed by the parties to the Merger Agreement in writing and as specified in a certificate of merger filed with the Secretary of State of the State of Delaware (the “Effective Time”), and the Second Company Merger will become effective as specified in a subsequent certificate of merger. Upon consummation of the Mergers and the other transactions contemplated by the Merger Agreement (the “Transactions”), Civitas and Merger Sub will cease to exist.

Under the terms of the Merger Agreement and as more fully described below, at the Effective Time, each share of Civitas common stock issued and outstanding immediately prior to the Effective Time (other than shares to be cancelled as described below) will be converted into the right to receive 1.45 shares (the “Exchange Ratio”) of common stock, par value $0.01 per share, of SM Energy (“SM Energy Common Stock”). Each share of Civitas common stock held in the treasury of Civitas or owned directly or indirectly by SM Energy or Merger Sub immediately prior to the Effective Time will be cancelled and will cease to exist, and no consideration will be delivered in exchange therefor. Each share of capital stock of Merger Sub outstanding immediately prior to the Effective Time will be converted into one share of capital stock of the First Surviving Corporation. The Merger Agreement also specifies the treatment of Civitas’ outstanding equity awards and warrants in connection with the Merger. In connection with the consummation of the Mergers, SM Energy’s certificate of incorporation (the “SM Energy Charter”) would be amended to increase the authorized number of shares of SM Energy Common Stock to 400,000,000 shares (the “SM Energy Charter Amendment”).

The board of directors of SM Energy (the “SM Energy Board”) unanimously (a) determined that the Transactions are in the best interests of, and are advisable to, SM Energy and its stockholders (the “SM Energy Stockholders”), (ii) approved, adopted and declared advisable the Merger Agreement, the SM Energy Charter Amendment, and the Transactions, (iii) directed that the issuance of SM Energy Common Stock in connection with the Mergers (the “Stock Issuance”) and the SM Energy Charter Amendment be submitted to the holders of SM Energy Common Stock for their approval and (iv) resolved to recommend that the SM Energy Stockholders approve the Stock Issuance and the SM Energy Charter Amendment.

SM Energy and Civitas have agreed to certain governance-related matters. At the Effective Time, the SM Energy Board (the “New Board”) will have 11 members, including (a) six directors from among the members of the SM Energy Board as of the date of the Merger Agreement, two of which will be designated by the Chairman of the SM Energy Board and four of which shall be designated by mutual agreement of the Chairman of each of the SM Energy Board and the Civitas Board and (b) five directors from among the members of the Civitas Board as of the date of the Merger Agreement, two of which will be designated by the Chairman of the Civitas Board and three of which shall be designated by mutual agreement of the Chairman of each of the SM Energy Board and Civitas Board. The Chairman of the SM Energy Board as of immediately prior to the Effective Time will serve as Chairman of the New Board.

The closing of the Mergers is subject to the satisfaction or waiver of certain closing conditions, including, among others, (i) adoption of the Merger Agreement by the affirmative vote of the holders of a majority of the outstanding shares of Civitas Common Stock entitled to vote thereon (the “Civitas Stockholder Approval”), (ii) approval of (a) the Stock Issuance by affirmative vote of the holders of a majority of the outstanding shares of SM Energy Common Stock present in person or represented by proxy at a special meeting of the SM Energy Stockholders and entitled to vote thereon and (b) the SM Energy Charter Amendment by the votes cast for the SM Energy Charter Amendment by the holders of outstanding shares of SM Energy Common Stock exceeding the votes cast against the SM Energy Charter Amendment by the holders of outstanding shares of SM Energy Common Stock, in each case, in accordance with the rules and regulations of the New York Stock Exchange (the “NYSE”), the Delaware General Corporation Law and the SM Energy organizational documents (collectively, the “SM Energy Stockholder Approval”), (iii) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or any other antitrust law relating to the Transactions, as well as any agreement not to close embodied in a “timing agreement” between the parties to the Merger Agreement and any governmental entity, (iv) no temporary restraining order, preliminary or permanent injunction or other judgment, order or decree issued by any court of competent jurisdiction or other legal restraint or prohibition being in effect, and no law having been enacted, entered, promulgated, enforced or deemed applicable by any governmental entity that, in any such case, prohibits or makes illegal the consummation of

The Merger Agreement contains customary representations and warranties of the parties to the Merger Agreement relating to their respective businesses, financial statements and public filings, as applicable, in each case generally subject to customary materiality and knowledge qualifiers. Additionally, the Merger Agreement provides for customary pre-closing covenants of SM Energy and Civitas, including covenants relating to conducting their respective businesses in the ordinary course and refraining from taking certain actions without the consent of the other party. SM Energy and Civitas also agreed to use their reasonable best efforts to consummate the Transactions and to obtain regulatory approvals.

The Merger Agreement provides that, from the date of the Merger Agreement, each of SM Energy and Civitas will be subject to certain restrictions on its ability to solicit an alternative Parent Acquisition Proposal or Company Acquisition Proposal (each as defined in the Merger Agreement), respectively, from third parties, to provide non-public information to third parties and to engage in discussions with third parties regarding alternative Parent Acquisition Proposals or Company Acquisition Proposals, as applicable, subject to customary exceptions. SM Energy is required to call a meeting of its stockholders to obtain the SM Energy Stockholder Approval. Civitas is required to call a meeting of its stockholders to obtain the Civitas Stockholder Approval. Neither party has the ability to terminate to accept a superior proposal prior to its stockholder meeting.

The Merger Agreement contains customary termination rights for each of SM Energy and Civitas, including, among others, if the Mergers have not been consummated by August 3, 2026 (subject to a limited extension to November 2, 2026 for the sole purpose of obtaining antitrust clearances), if required stockholder approvals are not obtained, or upon a change of recommendation or a material breach by the other party, in each case on the terms set forth in the Merger Agreement. In certain circumstances, including specified circumstances following a change of recommendation by the Civitas board or the receipt by Civitas of a competing acquisition proposal, Civitas will be required to pay SM Energy a termination fee of $85 million (the “Company Termination Fee”), and in reciprocal specified circumstances, SM Energy will be required to pay Civitas a termination fee of $79 million (the “SM Energy Termination Fee”). In other specified circumstances where the Merger Agreement is terminated following the failure to obtain the required stockholder approval and the Company Termination Fee or SM Energy Termination Fee, as applicable, is not otherwise payable, the party whose stockholders failed to approve the transactions will be required to pay the other party $26 million (if the Civitas Stockholder Approval is not obtained) or $24 million (if the SM Energy Stockholder Approval is not obtained), in each case as reimbursement for the other party’s transaction expenses.

The representations, warranties and covenants contained in the Merger Agreement have been made solely for the benefit of the parties thereto. In addition, such representations, warranties and covenants (i) have been made only for purposes of the Merger Agreement, (ii) have been qualified by (a) matters specifically disclosed in any reports filed by SM Energy or Civitas with the SEC prior to the date of the Merger Agreement (subject to certain exceptions) and (b) confidential disclosures made in confidential disclosure letters delivered in connection with the Merger Agreement, (iii) are subject to materiality qualifications contained in the Merger Agreement which may differ from what may be viewed as material by investors, (iv) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement and (v) have been included in the Merger Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as fact. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the parties thereto or their respective businesses. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties to the Merger Agreement or any of their respective subsidiaries or affiliates. 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 SM Energy’s public disclosures. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding SM Energy and Civitas that is or will be contained in, or incorporated by reference into, the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other documents that SM Energy or Civitas files with the SEC.

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act.

The words “intend,” “expect,” and similar expressions are intended to identify forward-looking statements. Forward-looking statements in this Current Report on Form 8-K include, but are not limited to, statements regarding the Transactions, pro forma descriptions of the combined company and its operations, integration and transition plans, synergies, opportunities and anticipated future performance. There are a number of risks and uncertainties that could cause actual results to

differ materially from the forward-looking statements included in this Current Report on Form 8-K. These include the expected timing and likelihood of completion of the Transactions, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the Transactions that could reduce anticipated benefits or cause the parties to abandon the Transactions, the ability to successfully integrate the businesses, the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, the possibility that stockholders of SM Energy or Civitas may not approve the Transactions, the risk that the parties may not be able to satisfy the conditions to the Transactions in a timely manner or at all, risks related to disruption of management time from ongoing business operations due to the Transactions, the risk that any announcements relating to the Transactions could have adverse effects on the market price of SM Energy’s common stock or Civitas’ common stock, the risk that the Transactions and its announcement could have an adverse effect on the ability of SM Energy and Civitas to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers and on their operating results and businesses generally, the risk the pending Transactions could distract management of both entities and they will incur substantial costs, the risk that problems may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected, the risk that the combined company may be unable to achieve synergies or it may take longer than expected to achieve those synergies and other important factors that could cause actual results to differ materially from those projected. All such factors are difficult to predict and are beyond SM Energy’s or Civitas’ control, including those detailed in SM Energy’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on its website at sm-energy.com/investors and on the SEC’s website at http://www.sec.gov, and those detailed in Civitas’ annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on Civitas’ website at ir.civitasresources.com/investor-relations and on the SEC’s website at http://www.sec.gov. All forward-looking statements are based on assumptions that SM Energy or Civitas believe to be reasonable but that may not prove to be accurate. Such forward-looking statements are based on assumptions and analyses made by SM Energy and Civitas in light of their perceptions of current conditions, expected future developments, and other factors that SM Energy and Civitas believe are appropriate under the circumstances. These statements are subject to a number of known and unknown risks and uncertainties. Forward-looking statements are not guarantees of future performance and actual events may be materially different from those expressed or implied in the forward-looking statements. The forward-looking statements in this Current Report on Form 8-K speak as of the date of this Current Report on Form 8-K.
