**Item 8.01 Other Events.** 

As previously announced, on November 2, 2025, SM Energy Company, a Delaware corporation ("SM Energy" or the "Company"), Cars Merger Sub, Inc., a Delaware corporation and direct wholly owned subsidiary of the Company ("Merger Sub"), and Civitas Resources, Inc., a Delaware corporation ("Civitas"), entered into an Agreement and Plan of Merger pursuant to which (i) Merger Sub will merge with and into Civitas, with Civitas surviving as a wholly owned subsidiary of the Company (the "First Company Merger"), and (ii) immediately following the First Company Merger, Civitas as the surviving corporation will merge with and into the Company, with the Company continuing as the surviving corporation (the "Second Company Merger" and, together with the First Company Merger, the "Mergers").

On December 5, 2025, the Company filed with the U.S. Securities and Exchange Commission (the "SEC") a Registration Statement on Form S-4 (Registration No. 333-291956) (the "Registration Statement"), which was declared effective by the SEC on December 19, 2025, and which included a joint proxy statement/prospectus of the Company and Civitas in connection with the Mergers (such joint proxy statement/prospectus as filed by the Company on December 22, 2025, the "Joint Proxy Statement/Prospectus").

***Stockholder Communications Related to the Mergers***

Since the filing of the Joint Proxy Statement/Prospectus, as of the date hereof, the Company has received multiple demand letters from purported stockholders of the Company (the "Demand Letters") alleging that the Joint Proxy Statement/Prospectus contains certain disclosure deficiencies and/or incomplete information regarding the Mergers. It is possible that additional, similar demand letters may be received by the Company regarding the Mergers or that complaints may be filed against the Company or the Company's board of directors. Absent new or different allegations that are material or a disclosure obligation under the U.S. federal securities laws, the Company will not necessarily disclose such additional demands or complaints.

The Company and the Company's directors deny that any further disclosure beyond that already contained in the Joint Proxy Statement/Prospectus is required under applicable law. However, in order to avoid the risk that the Demand Letters may delay or otherwise adversely affect the consummation of the Mergers, to avoid nuisance and minimize the distractions, uncertainties and expense inherent in litigation, and without admitting any liability or wrongdoing, the Company is voluntarily making certain disclosures below that supplement those contained in the Joint Proxy Statement/Prospectus. These disclosures, and disclosures of certain other matters, are provided in this Current Report on Form 8-K. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, the Company and the Company's directors specifically deny all allegations in the Demand Letters and specifically deny that any additional disclosure was or is required and that the supplemental disclosures below are otherwise material.

**SUPPLEMENT TO PROXY STATEMENT**

The Company is supplementing the Joint Proxy Statement/Prospectus with certain additional information set forth below. These disclosures should be read in connection with the Joint Proxy Statement/Prospectus, which should be read in its entirety and is available on the SEC's website at https://www.sec.gov, along with the periodic reports and other information the Company files with the SEC. The supplemental disclosures contained herein will not affect the timing of special meetings of the Company's and Civitas' stockholders, which are scheduled to be held on January 27, 2026, at 10:00 a.m. Mountain Time.

All page references are to pages in the Joint Proxy Statement/Prospectus, and terms used below, unless otherwise defined, have the meanings set forth in the Joint Proxy Statement/Prospectus. To the extent the following information differs from or conflicts with the information contained in the Joint Proxy Statement/Prospectus, the information set forth below shall be deemed to supersede the respective information in the Joint Proxy Statement/Prospectus. New text within the amended and supplemented language from the Joint Proxy Statement/Prospectus is indicated in bold and underlined text (e.g., **<u>bold, underlined text</u>**), and deleted text within the amended and supplemented language from the Joint Proxy Statement/Prospectus is indicated in bold and strikethrough text (e.g., **bold, strikethrough text**).

***The disclosure beginning on page 89 of the Joint Proxy Statement/Prospectus under the heading "The Mergers—Opinion of the SM Energy's Financial Advisor—Net Asset Value Analyses—SM Energy" is hereby revised and supplemented as follows:***

Evercore calculated the after tax net present value, as of October 1, 2025, of future cash flows SM Energy was expected to generate based on the reserves data relating to SM Energy included in the SM Energy management forecasts (the "SM Energy reserves database") and using forecasted oil and natural gas prices estimated by SM Energy's management and approved by SM Energy for Evercore's use ("management pricing"). For purpose of its analysis, Evercore selected discount rates ranging from 8% to 30% based on its professional judgment and experience depending on the perceived risk profile of the reserve categories. Using the various discount rates depending on the reserve category, Evercore discounted to present value, as of October 1, 2025, the pre-tax cash flows estimated to be generated by SM Energy from the various reserve categories, as reflected in the SM Energy reserves database, to derive a range of total reserve value. Based on this range of total reserve value, the present value of other capital expenditures, the present value of the future estimated effects of SM Energy's hedging, using a selected discount rate ranging from 5% to 8% **<u>(selected by Evercore using its professional judgment and experience)</u>**, the present value of the general and administrative expenses, the present value of cash taxes (discounted using a range of discount rates based on the weighted average of discount rates applied to the pre-tax cash flows by reserve category), SM Energy's estimated net debt **and cash** **<u>of approximately $2,574 million</u>** as of September 30, 2025, and the number of fully diluted outstanding shares of SM Energy common stock **<u>of approximately 116.8 million</u>** as of October 29, 2025, in each case based on the SM Energy management forecasts, this analysis indicated a range of implied equity values per share of SM Energy common stock of $15.47 to $22.63, as compared to the closing price of SM Energy common stock of $20.54 on October 30, 2025.

***The disclosure beginning on page 89 of the Joint Proxy Statement/Prospectus under the heading "The Mergers—Opinion of the SM Energy's Financial Advisor—Net Asset Value Analyses—Civitas" is hereby revised and supplemented as follows:***

Evercore calculated the after tax net present value, as of October 1, 2025, of future cash flows Civitas was expected to generate based on the reserves data relating to Civitas included in the SM Energy management forecasts (the "Civitas reserves database") and using the management pricing. For purpose of its analysis, Evercore selected discount rates ranging from 8% to 30% based on its professional judgment and experience depending on the perceived risk profile of the reserve categories. Using the various discount rates depending on the reserve category, Evercore discounted to present value, as of October 1, 2025, the pre-tax cash flows estimated to be generated by Civitas from the various reserve categories, as reflected in the Civitas reserve database, to derive a range of total reserve value. Based on this range of total reserve value, the present value of capital expenditures, the present value of the future estimated effects of Civitas' hedging, the present value of the general and administrative expenses, the present value of cash taxes (discounted using a range of discount rates based on the weighted average of discount rates applied to the pre-tax cash flows by reserve category), the present value midstream expenses, Civitas' estimated pro forma net debt **and cash** **<u>of approximately $4,945 million</u>** as of September 30, 2025 (after giving effect to certain asset sales estimated to occur subsequent to September 30, 2025, as furnished by management of SM Energy), and the number of fully diluted outstanding shares of Civitas common stock **<u>of approximately 87.1 million</u>** as of October 30, 2025, in each case based on the SM Energy management forecasts, this analysis indicated a range of implied equity values per share of Civitas common stock of $23.22 to $33.09, as compared to the closing price of Civitas common stock of $28.72 on October 30, 2025 and the implied offer price of Civitas common stock of $29.78 (calculated by multiplying the closing price of SM Energy common stock of $20.54 on October 30, 2025 by the exchange ratio of 1.45x pursuant to the merger agreement).

***The disclosure beginning on page 90 of the Joint Proxy Statement/Prospectus under the heading "The Mergers—Opinion of the SM Energy's Financial Advisor—Discounted Cash Flow Analysis—SM Energy" is hereby revised and supplemented as follows:***

The cash flows and terminal values in each case were then discounted to present value as of October 1, 2025, using discount rates ranging from 8.50% to 10.00%, representing an estimate of SM Energy's weighted average cost of capital, as estimated by Evercore based on its professional judgment and experience **<u>and based on the application of the capital asset pricing model, which requires certain company-specific inputs, including debt to equity ratio, debt to total capitalization ratio, pre-tax cost of debt, and levered and unlevered betas, as well as certain financial metrics for the United States financial markets generally</u>**, to derive implied enterprise value reference ranges for SM Energy. Based on these ranges of implied enterprise values, SM Energy's estimated pro forma net debt **and cash** **<u>of approximately $2,574 million</u>** as of September 30, 2025, and the number of fully diluted outstanding shares of SM Energy common stock **<u>of approximately 116.8 million</u>** as of October 30, 2025, in each case based on the SM Energy management forecasts, this analysis indicated ranges of implied equity values per share of SM Energy common stock as set forth in the table below, as compared to the closing price of SM Energy common stock of $20.54 on October 30, 2025:

Evercore reviewed selected publicly available share price targets of **<u>16</u>** research analysts' estimates **<u>for each company</u>** known to Evercore as of October 30, 2025, noting that the low and high share price targets ranged from (i) $19.00 to $56.00 for SM Energy common stock, as compared to the closing price of SM Energy common stock of $20.54 on October 30, 2025, and (ii) $27.00 to $80.00 for Civitas common stock, as compared to the closing price of Civitas common stock of $28.72 on October 30, 2025, and the implied offer price of Civitas common stock of $29.78. Public market trading price targets published by equity research analysts do not necessarily reflect current market trading prices for the shares of SM Energy common stock and Civitas common stock and these target prices and the analysts' earnings estimates on which they were based are subject to risk and uncertainties, including factors affecting the financial performance of SM Energy, Civitas and future general industry and market conditions..
