SEC filingSolaris Power Solutions drove 122% total revenue growth in Q3, but heavy capex and debt raise raise cash flow questions.
For the three months ended September 30, 2025, total revenue reached $166.8 million, a 122% increase compared to $75.0 million in the same period of 2024. This growth was almost exclusively driven by the Solaris Power Solutions segment, which contributed $104.9 million versus $4.7 million last year. Cost of revenue (exclusive of depreciation and amortization) grew to $88.8 million from $46.9 million, reflecting the scaling of the power business. Depreciation and amortization doubled to $22.4 million, while SG&A expenses rose 77% to $15.5 million due to higher headcount. Interest expense increased to $9.0 million from $2.9 million, reflecting higher debt levels. The effective tax rate swung from negative 26.3% to 14.1% due to changes in operating gains and state mix.
Solaris Power Solutions is the dominant growth driver, with revenues skyrocketing from a minimal base as the company deployed more megawatts of power generation equipment. Deployed capacity reached approximately 760 MW in Q3 2025, up from 150 MW in Q3 2024. The segment's cost of revenue as a percentage of revenue was 42%, versus 27% last year, indicating higher costs as the segment scales. In contrast, Solaris Logistics Solutions saw a 12% revenue decline to $61.9 million, with cost of revenue decreasing only 3% to $44.4 million, causing its cost ratio to rise to 72% from 65%. The logistics segment continues to be pressured by lower oilfield activity, with fully utilized systems down to 84 from 91.
Management expects total capital expenditures of approximately $405 million for the remainder of 2025, with the majority allocated to Solaris Power Solutions. The company ordered an additional 500 MW of power generation equipment, targeting total capacity of about 2,200 MW by early 2028. The majority of this capacity is committed under long-term contracts (2-7 years). The recent issuance of $747.5 million in 0.25% convertible notes due 2031 and an additional $43.9 million draw on the Stateline term loan have strengthened liquidity. However, the company faces significant purchase commitments of $209.8 million due within 12 months and $520.8 million beyond, with cancellation penalties ranging from 5% to 90%. Management believes cash, operating cash flows, and available credit are sufficient to meet obligations.
As of September 30, 2025, the company held $106.7 million in cash and equivalents, down from $159.9 million (including restricted cash) at year-end 2024. Total debt stood at $532.3 million, comprising $382.8 million in long-term debt (net of financing costs) and $149.5 million in convertible notes. Shareholders' equity was $859.0 million, with a non-controlling interest of $312.4 million primarily from Solaris LLC and the Stateline VIE. Inventories totaled $13.8 million, and deferred revenue was $6.7 million.
The company disclosed $730.6 million in material purchase commitments for power generation equipment as of September 30, 2025. Of this, $209.8 million is due within the next 12 months, with the remainder extending into 2026 ($399.7 million) and beyond. Notably, $450.4 million of these commitments are related to the Stateline VIE, which are non-recourse to the company. Additionally, the company has a guarantee of lease agreement totaling $1.8 million.
Dividends totaled $15.4 million for the nine months ended September 30, 2025, at a quarterly rate of $0.12 per Class A share. Debt activity included the issuance of $155.0 million in 4.75% convertible senior notes due 2030 (net proceeds $150.3 million) and an initial draw of $72.0 million on the Stateline term loan facility (capacity up to $550.0 million). Capital expenditures were $392.3 million, heavily weighted toward Solaris Power Solutions ($386.8 million) for power generation assets. No share buybacks were reported during the period.
Segment data (Note 3) shows two reportable segments: Solaris Power Solutions and Solaris Logistics Solutions. For the nine months ended September 30, 2025, Power Solutions generated $229.9 million in revenue and $135.7 million in Adjusted EBITDA; Logistics Solutions generated $212.6 million in revenue and $66.1 million in Adjusted EBITDA. Segment assets were $1,058.2 million for Power Solutions and $348.3 million for Logistics Solutions. Revenue from the Power Solutions segment is predominantly leasing (83% of nine-month revenue) and includes sublease income of $74.3 million. No geographic breakdown is provided in the notes.
Operating cash flow (CFO) of $113.2M far exceeded net income of $61.9M, indicating strong cash conversion. The main reconciling items were depreciation ($60.8M) and stock-based compensation ($17.5M). However, capex of $392.3M was huge, driven by investments in power generation equipment for the Stateline project and other expansions. This resulted in negative free cash flow, necessitating significant financing: $227M in debt and $86M from non-controlling interest. Working capital was a net use of cash, notably a $52.6M increase in accounts receivable. Dividends of $15.4M were covered by CFO but not by FCF. The abnormally high capex reflects a growth phase; investors should monitor return on these investments.
