Solaris Energy Infrastructure Inc. (NYSE: SEI) completed approximately $2 billion in financing transactions and expanded an existing power contract, the company announced.

The Houston-based company closed its inaugural bond offering of $1.3 billion in senior, unsecured notes at a rate of 6.375%. The proceeds were used to retire higher-cost debt and resulted in approximately $800 million of net proceeds added to the balance sheet. The company also established a new $650 million credit facility.

Solaris signed an amendment to expand its original contract, initially signed in February 2026 for more than 500 MW, to provide an additional 130 MW and enhanced balance of plant scope. The expansion increases Solaris' total contracted project investment by more than 60%. The contract maintains its 10-year tenor with a 5-year extension option.

The financing proceeds, combined with expected cash flow from operations, are expected to fund the company's current capital expenditure commitments, according to the press release.

Bill Zartler, Chairman and Co-Chief Executive Officer, and Amanda Brock, Co-Chief Executive Officer, stated that two-thirds of the company's 3.1 GW current and on-order capacity is under long-term contracts.

Solaris Energy Infrastructure provides power generation and distribution solutions, and logistics equipment and services to clients in the data center, energy, and other commercial and industrial sectors.
