Executive summary

SOLV Energy Q4 FY25 — Record Performance Driven by Strong Backlog and O&M Growth

SOLV Energy reported record Q4 and full-year FY25 results, driven by strong demand in utility-scale solar and storage, particularly from data center growth. The company's substantial backlog and growing O&M services position it for continued expansion, leveraging its full lifecycle service model and scale. While FY26 gross margin guidance reflects new project starts, management remains focused on disciplined execution and strategic inorganic growth to expand service offerings.

Concerns

3
  • Gross margin guidance for FY26 (15.6%-16.2%) is lower than FY25 realized gross margin (over 18%), attributed to new project starts.

  • Fuel costs, while currently having less than 1% direct impact on project costs, are being monitored for potential shipping cost impacts.

  • Potential for supply chain disruptions from the Middle East is being monitored, though none are currently observed.

Why it matters

To assess if the anticipated margin normalization due to new project starts aligns with guidance and if productivity enhancements begin to show impact.

But with all these new starts and everything that comes with that, we feel like we're in a range of what we view as a reasonable assumption, certainly at the start.

Q&A highlights

How should investors think about the seasonality of gross margin and the 2026 gross margin guidance (15.6%-16.2%) compared to the strong 2025 performance (over 18%)?

Management explained that 2025 saw exceptionally strong performance, including large, unforecasted repair projects that boosted margins. The 2026 guidance reflects new project starts, which typically have lower margins initially, but the company expects productivity enhancements over time. The range is considered a reasonable assumption for the start of the year.

“As projects start, we've got a view of how we think about underwriting. And I think as we spent a lot of time on the road prior to the -- speaking with everybody. And I think as we see performance and productivity enhancement over time, we certainly know that there is the ability to see higher margins. But with all these new starts and everything that comes with that, we feel like we're in a range of what we view as a reasonable assumption, certainly at the start.”

Detailed narrative

Market Environment & Demand

The U.S. is experiencing an unprecedented surge in electricity demand, primarily driven by data center growth and manufacturing reshoring. Digital infrastructure and manufacturing investments are running at roughly 3x historical averages, and expected load growth has increased almost fivefold. Solar and storage build rates have nearly tripled, positioning them uniquely to meet reliability needs and demand for carbon-free solutions, as solar remains the lowest cost source of new generation.

Competitive Advantage & Lifecycle Services

SOLV Energy provides life cycle infrastructure services to the U.S. power sector, covering design, procurement, construction (EPC), and long-term operations and maintenance (O&M) for the full 35-year life of power plants. This end-to-end model differentiates the company from EPC-only peers, driving best-in-class execution and fostering long-term customer partnerships.

EPC is the largest spend category, and when paired with O&M, it creates predictable, recurring revenue streams through 5-year contracts with automatic annual renewals.

O&M Growth Opportunity

The O&M business manages over 20 gigawatts of operating assets across 150 power plants. The estimated long-term revenue opportunity from the installed base is significant, projected at $7.4 billion over a 35-year project life for preventative maintenance, corrective maintenance, and inverter replacements.

Only $540 million of this is currently reflected in the backlog, highlighting substantial future revenue potential. Industry forecasts predict a 3.8x increase in operating utility-scale solar and storage capacity by 2034, aligning well with SOLV's growth trajectory.

Growth Strategy & Execution

SOLV's growth strategy focuses on projects above 200 megawatts, expanding its O&M business, entering adjacent markets, investing in innovation (digital tools, construction methods, predictive maintenance), and pursuing strategic acquisitions. The company emphasizes its ability to scale, noting that backlog growth is driven by larger projects rather than an increased number of projects.

This allows for leverage of project teams and efficient execution, a capability developed over nearly two decades.
