#### Explanatory Note
On March 20, 2026, Solaris Energy Infrastructure, Inc. (the "Company") filed a Current Report on Form 8-K (the "Original Report") with the U.S. Securities and Exchange Commission. The Original Report disclosed, among other things, the consummation of the acquisition of Focus Genco Cayman Ltd. ("Genco") by the Company as contemplated by the Securities Purchase Agreement, dated March 16, 2026 (the "Transaction").

The Company is filing this Amendment No. 1 to the Original Report to revise Items 2.01 and 9.01 to clarify that, upon further evaluation, the Transaction does not constitute the acquisition of a "significant amount of assets" under Rule 3-05 of Regulation S-X. Accordingly, no historical financial statements of Genco or pro forma financial information are required to be filed under Item 9.01(a) and (b), respectively, in connection with the Transaction.

Except as provided herein, the disclosures made in the Original Report remain unchanged.
