SOLV Energy (MWH) Q4 2025 earnings review
Hyper-Growth Secured by Backlog, but Profitability Reverses
SOLV Energy's first earnings report as a public company delivered blockbuster top-line numbers, with Q4 revenue surging 80% YoY and backlog expanding 87% to $8 billion. The company is successfully riding the macro wave of infrastructure demand. However, the FY26 guidance reveals a stark divergence: while revenue growth is accelerating, profitability is sharply reversing. Guided gross margins of 15.6%-16.2% mark a significant step down from FY25's 18.6%, resulting in EBITDA growth heavily lagging sales growth.
🐂 Bull Case
The $8 billion backlog (up 87% YoY) guarantees massive volume in FY26. Revenue guidance midpoint of $3.77 billion implies 51% YoY growth, accelerating from the 35% growth achieved in FY25.
Operating cash flow nearly tripled to $331.6M in FY25. Combined with $552.5M in net IPO proceeds and the repayment of their term loan, SOLV's balance sheet is primed for scale.
🐻 Bear Case
Despite massive scale, FY26 gross margin guidance implies a ~270 bps drop to 15.9% at the midpoint. This suggests SOLV may be bidding aggressively on lower-margin projects to fuel its backlog growth.
Q4 SG&A expenses spiked 106% YoY to $83M, easily outpacing the 80% revenue growth. The lack of operating leverage is a red flag for a company scaling this rapidly.
⚖️ Verdict: ⚪
Neutral. The volume and backlog story is undeniably bullish, but the aggressive margin compression guided for FY26 contradicts the narrative of a fully healthy growth cycle. Investors are paying for top-line expansion but sacrificing bottom-line leverage.
Key Themes
Massive Backlog Expansion Fuels Revenue Acceleration
Backlog ended the year at $8.0 billion, an 87% YoY increase (implying 2024 backlog was roughly $4.3 billion). This extraordinary booking pace gives management the confidence to guide for over 50% revenue growth in FY26, heavily de-risking the top-line story.
Gross Margin Reversal Contradicts Scale Narrative
A major red flag: SOLV reported an 18.6% gross margin for FY25, but FY26 guidance models a drop to 15.6% - 16.2%. In a healthy infrastructure scaling model, margins should at least remain stable. This 270 bps compression implies the company is either facing severe cost inflation (labor/materials) or intentionally absorbing lower-margin EPC contracts to inflate the backlog.
Sustained Macro Demand for Power Infrastructure
Management directly attributed their record performance to 'sustained demand for infrastructure services.' With utility-scale power plant development booming, SOLV has built over 500 plants representing 21 GW of generating capacity to date, capturing a significant piece of the U.S. renewable transition.
SCADA and Tech Integration Enhancing O&M Scale
SOLV is moving beyond simple construction by deploying end-to-end SCADA (Supervisory Control and Data Acquisition) and network infrastructure solutions. This technology overlay is crucial for securing long-term Operations & Maintenance (O&M) contracts. The O&M portfolio has now reached over 20 GW under contract, establishing a recurring revenue base to smooth out lumpy EPC project timing.
SG&A Bloat Eclipsing Operating Leverage
In Q4, SG&A expenses came in at $83.3M, up 106% from $40.4M a year ago. Revenue over the same period grew 80%. Even adjusting for typical public company readiness costs, operating expenses are rising faster than sales, limiting the flow-through of the top-line beat to net income.
Other KPIs
Accelerating significantly from $117.6M in FY24. This was driven by a $109M favorable swing in Accounts Payable and Accrued Expenses, showing excellent working capital management as the company scales its project deployments.
Up 89% YoY from $53.0M. The current quarter showed excellent execution with EBITDA margins stable at roughly 12.6%. However, guidance suggests this level of profitability will not be sustained into 2026.
Guidance
Accelerating. The midpoint of $3.77 billion represents a 51.4% YoY increase over FY25's $2.49 billion. This is a dramatic step-up from the 34.7% growth seen in FY25, fully backed by the massive surge in year-end backlog.
Decelerating growth vs revenue. The implied gross margin is 15.6% to 16.2%. Reversing from the strong 18.6% achieved in FY25, indicating that the new revenue layer carries a fundamentally lower margin profile.
Decelerating. The $410M midpoint implies just under 20% YoY growth, a massive slowdown from the 107% growth achieved in FY25. The core story here is that 51% revenue growth is only generating 20% EBITDA growth due to significant margin compression.
Key Questions
Gross Margin Compression
With FY26 gross margin guided down nearly 300 basis points compared to FY25, is this driven by a shift in project mix, aggressive pricing to win the $8B backlog, or anticipated inflation in labor and materials?
Backlog Burn Rate
Of the $8 billion backlog, what percentage is expected to be recognized as revenue in FY26, and how much is tied to long-term O&M contracts versus immediate EPC delivery?
SG&A Normalization
SG&A more than doubled in Q4 YoY. Excluding IPO readiness and transaction fees, what is the normalized run-rate for SG&A going into FY26, and when will investors see positive operating leverage?
