Appointment of Chief Financial Officer and Principal Financial Officer

On February 12, 2026 (the “Effective Date”), the Board of Directors (the “Board”) of Solaris Energy Infrastructure, Inc. (the “Company”) appointed Stephan E. Tompsett as Chief Financial Officer of the Company. Mr. Tompsett will serve as the principal financial officer of the Company.

Prior to joining the Company, Mr. Tompsett, age 49, served as the Chief Financial Officer of Aris Water Solutions, Inc. (formerly NYSE: ARIS) from September 2022 until October 2025. From May 2021 until May 2022, Mr. Tompsett served as Chief Financial Officer of Limetree Bay Energy, a large-scale refinery, terminal and logistics hub located in the U.S. Virgin Islands. During his tenure at Limetree Bay Energy, Mr. Tompsett was a member of the turnaround management team responsible for leading the financial restructuring and eventual Chapter 11 bankruptcy filing and sale of Limetree Bay Refining, and the separation and recapitalization of Limetree Bay Terminals. Prior to this, Mr. Tompsett served as the Chief Financial Officer and Treasurer of EagleClaw Midstream Ventures, LLC, a Blackstone portfolio company engaged in natural gas gathering, transportation, and processing in the Delaware Basin from March 2019 to April 2021. Mr. Tompsett served as Vice President and Treasurer of Andeavor (formerly Tesoro Corporation), a Fortune 500 independent refining, marketing and logistics company from September 2016 to October 2018. He began his career at JPMorgan as an investment banker. Mr. Tompsett holds a Master of Business Administration degree from the Red McCombs School of Business at the University of Texas at Austin, and a Bachelor of Science degree in Biology and Mathematics from the University of Texas at Austin.

There are no family relationships between Mr. Tompsett and any director or executive officer of the Company or any person nominated or chosen by the Company to become a director or executive officer. There are no arrangements or understandings between Mr. Tompsett and any other person pursuant to which Mr. Tompsett was appointed as the Company’s Chief Financial Officer. The Company is not aware of any transaction involving Mr. Tompsett that would require disclosure under Item 404(a) of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Company has not entered into any material plan, contract or arrangement with Mr. Tompsett, as the terms of Mr. Tompsett’s compensation in connection with his appointment as Chief Financial Officer are still being finalized. To the extent required under applicable rules, the Company will disclose any compensation terms in a subsequent filing to be made by the Company under the Exchange Act.

In connection with Mr. Tompsett’s appointment, as of the Effective Date, Kyle Ramachandran ceased serving as the Company’s Chief Financial Officer, a position he has held since the Company’s initial public offering, in order to focus on the continued growth of the Company’s power business. Mr. Ramachandran will continue to serve as the Company’s President and head of the Company’s Solaris Power Solutions segment.

Indemnification Agreement

In connection with Mr. Tompsett’s appointment as Chief Financial Officer, the Company entered into an Indemnification Agreement (“Indemnification Agreement”) with Mr. Tompsett. The Indemnification Agreement requires the Company to indemnify Mr. Tompsett to the fullest extent permitted under Delaware law against liability that may arise by reason of his service to the Company and to advance expenses incurred as a result of any proceeding against him as to which he could be indemnified.

The foregoing description of the Indemnification Agreement is not complete and is qualified in its entirety by reference to the full text of the Indemnification Agreement, which is attached as Exhibit 10.1 to this Current Report on Form 8-K, and incorporated herein by reference.
