What Solaris Energy Infrastructure, Inc. told the SEC could break it.
Solaris is concentrated at both ends of its business to an unusual degree. On the customer side, a single data center customer (with affiliates) accounted for about 47% of consolidated revenue in 2025 — and 88% of its fast-growing Power Solutions segment — so losing that customer, or failing to redeploy equipment at similar utilization and pricing, would severely impair results. On the supply side it is just as dependent: one supplier made up 51% of total purchases in 2025 and 71% of year-end accounts payable, pointing to heavy reliance on a single dominant equipment or turbine vendor it cannot easily replace. Because it builds equipment-based power and logistics systems from imported materials, U.S. tariffs — a 10% baseline plus reciprocal tariffs — are a direct, and rising, input-cost pressure on that concentrated supply chain.

In its own words
What could break it.
Customer concentration
- One data center customer = ~47% of consolidated revenue (88% of Power Solutions segment); a second customer = ~13%high
Solaris has extreme customer concentration, especially in its growing Power Solutions (distributed power) segment, which is significantly dependent on a single data center customer that made up 88% of segment revenue in 2025 (96% in 2024). At the consolidated level, that one data center customer (with affiliates) accounted for ~47% of total revenue in 2025, and another customer ~13%; its Logistics Solutions segment is likewise concentrated (one customer 28%, another 12%). Two customers represented 38% and 18% of accounts receivable. If it were to lose this material data center customer (or fail to redeploy equipment at similar utilization/pricing), results would be severely impaired. Customers are unnamed in the disclosure, so this registers as a high-severity concentration risk.
“Revenue in this segment is currently significantly dependent on a single data center customer, which made up 88% and 96%, respectively, of total segment revenue for the years ended December 31, 2025 and December 31, 2024.”
SEC filing →As of 2026
Supplier concentration
- One supplier = 51% of total purchases (71% of accounts payable) — single dominant equipment/turbine supplierhigh
Solaris's supply base is as concentrated as its customer base: one supplier accounted for 51% of the Company's total purchases in 2025 (38% in 2024, none over 10% in 2023), and at year-end 2025 a single supplier represented 71% of accounts payable. For an equipment-based business scaling distributed power generation, this points to heavy reliance on one dominant equipment/turbine vendor whose capacity, lead times, pricing, or contractual terms it cannot easily replace. A disruption, allocation event, or price increase at this single supplier could constrain its ability to build out and deliver power and logistics systems. The supplier is unnamed, so this registers as a high-severity sole-source/supplier-concentration risk.
“For the year ended December 31, 2025, one supplier accounted for 51 % of the Company's total purchases.”

Regulatory & policy
- U.S. tariffs (10% baseline + reciprocal tariffs) raising material/equipment input costsmedium
Because Solaris builds equipment-based power and logistics systems that incorporate imported materials and components, U.S. trade policy is a direct cost exposure. It discloses the 10% baseline tariff on products from virtually all foreign countries plus individualized reciprocal tariffs on major trade-deficit countries, and tariffs on certain imported materials, and states that as a result of the administration's trade policies, tariffs have increased and may increase its material input costs — with further trade restrictions/retaliatory measures potentially raising input costs more. Combined with its single-supplier concentration, tariff-driven cost increases on key equipment inputs could pressure margins. A concrete trade-policy exposure on its equipment supply chain.
“As a result of the administration's trade policies, tariffs have increased and may increase our material input costs.”
