Material Changes vs. Prior Period
- Revenue Growth: Driven almost entirely by the Solaris Power Solutions segment, which grew from $4.7 million to $229.9 million year-over-year due to increased deployed capacity (approx. 760 MW vs. 150 MW). Solaris Logistics Solutions revenue remained relatively flat ($212.6 million vs. $212.1 million).
- Profitability: Operating income increased significantly to $95.5 million, aided by the high-margin growth in power solutions and the absence of a $4.1 million loss on debt extinguishment recorded in the prior year.
- Acquisitions: Completed the acquisition of HVMVLV, LLC on August 15, 2025, for $60.1 million to enhance power control capabilities.
- Variable Interest Entity (VIE): Formed Stateline Power, LLC in April 2025 to provide off-grid power to a data center campus. Stateline is consolidated, contributing significant assets ($247.4 million) and non-controlling interest ($86.4 million).
Guidance, Outlook, and Risks
- Capital Expenditure Outlook: Management expects total company capital expenditures for the remainder of 2025 to be approximately $405 million, with the majority supporting Solaris Power Solutions.

- Subsequent Events (Post-Sept 30):
- Issued $747.5 million of 0.25% Convertible Senior Notes due 2031 (2031 Notes) in October 2025.

- Stateline drew an additional $43.9 million under its term loan facility.

Investor Verification Checklist
- Verify the sustainability of the Solaris Power Solutions revenue growth and the specific terms of the long-term contracts with data center customers.
- Review the Stateline Power, LLC structure, specifically the non-recourse nature of its debt and the risks associated with the single major customer (CTC/MZX).
- Assess the impact of the new 2031 Convertible Notes on future dilution and interest obligations, noting the low coupon rate (0.25%) but potential conversion risk.
- Monitor the litigation status, particularly the Stephen Pirello class action and the Masaba Inc. IP infringement case.
- Confirm the execution of the $405 million remaining capital expenditure plan and the funding sources (cash flow vs. debt).
