SEI · Solaris Energy Infrastructure, Inc.

Solaris Energy Infrastructure, Inc. and its subsidiary Solaris Energy Infrastructure, LLC entered into a Purchase Agreement on May 5, 2026, with Goldman Sachs & Co. LLC as representative of the initial purchasers, to sell $1.3 billion principal amount of 6.375% Senior Notes due May 15, 2031. The notes are senior unsecured obligations, fully and unconditionally guaranteed by the parent company and subsidiary guarantors, excluding unrestricted subsidiaries Solaris Power Solutions Stateline, LLC and Stateline Power, LLC. Issued at par in a Rule 144A/Regulation S private placement, the offering yields net proceeds of about $1,279.3 million after initial purchaser discounts and estimated expenses. Closing is anticipated on May 12, 2026, pending customary conditions. The proceeds will primarily repay existing borrowings, including portions benefiting affiliates of the initial purchasers who are lenders under the company's bridge term loan, while supporting fees, general corporate needs, and growth capital expenditures. This refinancing strengthens the capital structure by extending maturities and funding expansion in mobile power generation and oilfield services, with the Purchase Agreement including standard protections like representations, warranties, indemnification, and termination rights. A press release on the same date confirmed the pricing and terms.
