• Net cash used in investing activities significantly increased by $232.1 million to $422.1 million for the nine months ended September 30, 2025, reflecting substantial capital expenditures.

Risks

• High supplier concentration: Two suppliers accounted for 33% and 23% of total purchases for the three months ended September 30, 2025, and one supplier accounted for 47% for the nine months ended September 30, 2025.
• Dependence on domestic spending and access to capital markets, particularly in power generation and the oil and natural gas industry.
• Uncertainty regarding future actions of oil producers (e.g., OPEC, Russia) affecting production levels and market stability.
• Volatility in political, legal, and regulatory environments, including potential government shutdowns or geopolitical risks (Russia-Ukraine war, Israel-Hamas conflict).
• Inflationary risks, increased interest rates, central bank policy, bank failures, and supply chain constraints impacting material and labor costs.
• Potential for large or multiple customer defaults, including those from insolvencies.
• Technological advancements in well completion technologies and the company's ability to adapt and expand product offerings.
• Competitive conditions in the industry and inability to fully protect intellectual property rights.
• Risks associated with Stateline Power, LLC, including demand for AI-related off-grid power, need for additional financing, regulatory frameworks, and potential difficulties in redeploying assets.
• Exposure to short selling strategies and related litigation, such as the federal securities lawsuit and derivative complaint alleging misleading statements regarding the MER Acquisition.
• Inability to raise funds necessary to repurchase convertible notes or pay cash amounts due upon maturity or conversion, potentially restricted by other indebtedness.
• Dilution of ownership interests and potential depression of stock price upon conversion of convertible notes.
• Conditional conversion features of convertible notes could adversely affect financial condition and operating results, potentially reclassifying long-term debt as current liability.
• Accounting methods for convertible notes may adversely affect reported financial condition and results, with higher interest expense for accounting purposes than cash payments.
• Significant termination penalties (5% to 90% of purchase price) for cancellable purchase commitments.

Future Outlook

The Solaris Power Solutions segment is expected to continue its significant growth, driven by increasing demand for power in the U.S. and constrained electrical grid infrastructure. The company anticipates its power generation capacity to reach approximately 2,200 MW by early 2028, with most capacity already committed under long-term agreements. Total company capital expenditures for the remainder of 2025 are projected at $405 million, primarily supporting Power Solutions. Funding for planned capital expenditures will come from available cash, operating cash flows, existing credit facilities, and potentially opportunistic capital market transactions. The sustainability of power sector demand depends on generative AI computing growth, supply chain availability, regulatory changes, and economic activity. For Solaris Logistics Solutions, demand is influenced by oil and natural gas well drilling and completion activity, with recent declines in system utilization.

Management Comments

• Solaris Power Solutions segment continued to grow significantly, reflecting returns on the capital investments the Company has made to grow its revenue and earnings contribution from providing power generation solutions.
• We believe continued demand for our power assets will drive Solaris Power Solutions to continue to be the dominant segment in terms of Revenue and Adjusted EBITDA contribution.
• Solaris power offerings are configurable and can be scaled to match power demand on a behind-the-meter or distributed basis in a shorter timeline than many grid-based providers can service.
• We intend to fund the majority of our current planned capital expenditures with available cash, cash flows from operations, available capacity under our revolving credit facility, and proceeds from the Stateline debt financing facility.
• Even if we are unable to secure the financing of our planned capital expenditures, we have the ability to cancel the committed purchase orders and incur cancellation fees.
• The sustainability of this favorable supply-demand dynamic in the power sector will depend on multiple factors, including continued demand growth for generative AI computing applications, supply chain availability for electrical equipment, potential regulatory changes, overall economic activity levels, the level and pace at which the power industry can invest in power infrastructure, and the pace of continued electrification-driven demand growth.
• The level of demand over the longer term for Solaris Logistics Solutions will depend on multiple factors, including commodity price levels, customer consolidation that can drive activity and procurement strategy changes and industry efficiency gains, geopolitical risk, economic activity, potential regulatory changes and potential impacts from geopolitical disruptions.

Industry Context

The company's strong performance in Solaris Power Solutions aligns with broader industry trends of accelerating demand for power generation in the U.S., particularly from data centers and AI computing sectors, against a backdrop of constrained electrical grid infrastructure. The ability to provide flexible, on-demand power infrastructure positions Solaris favorably in this environment. Conversely, the Solaris Logistics Solutions segment's decline reflects the volatility and lower activity levels in the U.S. oil and natural gas well drilling and completion sector, which is sensitive to commodity prices and geopolitical risks.

Stakeholder Impact

• Shareholders: Positive impact from increased net income and EPS, continued dividend payments ($0.12/share), but potential dilution from convertible notes and ongoing litigation risks.
• Employees: Increased headcount and higher employee costs in the Solaris Power Solutions segment, indicating growth and job opportunities.
• Customers: Expansion of power generation solutions (e.g., Stateline, HVMVLV acquisition) aims to meet accelerating demand, particularly in data centers and AI computing.
• Suppliers: Significant purchase commitments for power generation equipment indicate strong demand for supplier services, but concentration risk with two main suppliers.
• Creditors: Debt refinancing with 2031 Notes extends maturity profile and enhances liquidity, but increased overall debt levels and capital commitments require careful monitoring.

Next Steps

• Finalize the purchase price and related allocation for the HVMVLV Acquisition within the measurement period (up to one year from acquisition date).
• Continue to fund growth-related capital expenditures, with approximately $405 million remaining in 2025, including $190 million by Stateline.

Key Dates

Recommendation

The company's strong financial performance, particularly the explosive growth in its Solaris Power Solutions segment, indicates successful strategic execution in a high-demand market. The significant investments in power generation capacity and strategic acquisitions position it well for continued expansion. While the Logistics segment faces headwinds and legal proceedings introduce uncertainty, the overall growth trajectory, improved profitability, and proactive debt refinancing suggest a positive outlook for long-term investors. The expected increase in power generation capacity to 2,200 MW by early 2028, largely committed to customers, underpins future revenue stability. The risks, while notable, appear manageable in the context of the company's growth drivers.
