What this transaction means for investors

Energy infrastructure tied to data centers and electrification is no longer a niche trade. It is becoming a capital allocation theme. Solaris delivered $167 million in third-quarter revenue, up 12% sequentially, with net income of $25 million and $0.31 per diluted share. Total Adjusted EBITDA reached $68 million, also up 12% sequentially. The real engine is Power Solutions, where revenue jumped 39% sequentially to $105 million and segment Adjusted EBITDA climbed to $58 million.

Management raised fourth-quarter Adjusted EBITDA guidance to $65 million to $70 million and initiated first-quarter 2026 guidance of $70 million to $75 million. Meanwhile, the company issued $748 million of 0.25% convertible notes to fund expansion and repaid a $325 million term loan, leaving debt attributable to Solaris at about $497 million as of quarter end.

At 2% of portfolio assets, this position now rivals some core mid-cap holdings, and compared with larger stakes in software and biotech names like Pegasystems and Ligand, Solaris adds exposure to a different growth vector. Shares are up close to 100% over the past year. That momentum reflects execution. Long-term investors should watch fleet expansion toward 2,200 MW and whether cash generation keeps pace with ambitious capital spending.
