Insights

Energy infrastructure credit and M&A analyst

Solaris funds a sizable acquisition with equity and new term debt, reshaping its capital structure.

Solaris Energy Infrastructure acquired all shares of Genco for 4,182,772 common shares plus approximately $81 million cash. To support its strategy, it entered a senior secured term loan for $300 million and a Stonebriar term loan for $148.61 million, both secured by extensive collateral.

The term loan bears interest at Term SOFR plus 3.00% or Base Rate plus 2.00%, with covenants on leverage, interest coverage, secured debt, and a minimum $50 million unrestricted cash balance. These terms limit future borrowing flexibility but provide clear guardrails for lenders and management.

Solaris also terminated its prior ABL facility with no borrowings outstanding, simplifying its debt stack. Through an assumed turbine purchase agreement, a subsidiary obtained 30 gas turbine delivery slots expected to add about 500 megawatts of capacity between early 2027 and 2029, underpinning growth tied to the new Genco platform.

In addition, the Purchase Agreement contains covenants by the Sellers, including confidentiality obligations, non-solicitation covenants, and a 90-day lockup restricting the Sellers’ ability to transfer, sell, or otherwise dispose of the Equity Consideration, subject to certain conditions. The Sellers have agreed to indemnify the Buyer and its affiliates for losses arising from breaches of the representations and warranties made by Genco and the Sellers, as well as breaches of covenants or agreements made by the Sellers, subject to customary survival periods, a deductible, and a cap on certain indemnification claims.

Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties to the Purchase Agreement or any of their respective subsidiaries or affiliates.
