HOUSTON--(BUSINESS WIRE)--May 13, 2026-- Solaris Energy Infrastructure, Inc. (NYSE:SEI) (“Solaris” or the “Company”), today announced it has completed nearly $2 billion of financing transactions to support growth in the form of a new bond and revolving credit facility. The Company has also announced it has signed an amendment to expand an existing contract in size as well as enhanced balance of plant scope.

Key Updates

• Closed Approximately $2 Billion of Growth Financing. The Company closed on its inaugural bond offering $1.3 billion senior, unsecured notes at a rate of 6.375%, which was used to retire higher-cost debt and resulted in approximately $800 million of net proceeds added to balance sheet. The Company also put in place a new $650 million credit facility. Proceeds from these new financings, combined with expected cash flow from operations, are expected to fully fund the Company’s current capital expenditure commitments.

• Contract Upsize and Expansion. The Company has signed an amendment to expand its original >500 MW contract signed in February 2026 to provide an additional 130 MW and significantly enhanced balance of plant scope, which increases Solaris’ total contracted project investment by more than 60%. All other terms remain the same, including the contracted tenor of 10 years with a 5-year extension option.

CEO Commentary

Bill Zartler, Chairman and Co-Chief Executive Officer, and Amanda Brock, Co-Chief Executive Officer, jointly commented, "With two-thirds of our 3.1 GW current and on-order capacity under long-term contracts, expanding balance of plant project scope and a strengthened balance sheet, the company is well-positioned to continue executing the growth runway we see for behind-the-meter power demand. Solaris has the contracts, the capital, and the track record to keep delivering for our customers while generating strong returns for our shareholders."
