Audio By Carbonatix

HOUSTON--(BUSINESS WIRE)--Oct 6, 2025--

Solaris Energy Infrastructure, Inc. (“Solaris”) (NYSE:SEI) announced today, in a separate press release, its intention to offer, in an underwritten public offering, subject to market and other conditions, $600,000,000 aggregate principal amount of convertible senior notes due 2031 (the “notes”), plus up to an additional $90,000,000 aggregate principal amount of notes that the underwriters of the notes offering have the option to purchase from Solaris.

Concurrently with the offering of the notes, Morgan Stanley & Co. LLC, acting on behalf of itself and/or its affiliates (in such capacity, the “delta offering underwriter”), intends to offer, in a separate, underwritten offering, a number of shares of Solaris’s Class A common stock, par value $0.01 per share (“Class A common stock”), borrowed from third parties (the “concurrent delta offering”), to facilitate hedging transactions (whether physical and/or through derivatives) by some of the purchasers of the notes. The number of shares of Class A common stock subject to the concurrent delta offering will be determined at the time of pricing of the concurrent delta offering and is expected to be no greater than commercially reasonable initial short positions of such hedging investors in the notes. No new shares of Class A common stock will be issued, and Solaris will not receive any proceeds from the concurrent delta offering. The concurrent delta offering and the offering of the notes are contingent upon one another.

Solaris has filed a shelf registration statement on Form S-3 (including a prospectus) with the Securities and Exchange Commission (the “SEC”). The concurrent delta offering is being made only by means of the prospectus supplement and the accompanying prospectus. Before you invest, you should read the prospectus supplement and the accompanying prospectus and other documents that Solaris has filed with the SEC for more complete information about Solaris and the offering. You may obtain these documents free of charge by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, a copy of the prospectus supplement and the accompanying prospectus may be obtained from Morgan Stanley, 180 Varick Street, 2nd Floor, New York, New York 10014, Attention: Prospectus Department.
