Solv Energy (MWH) Q3 2026 earnings review
Solv Energy raises its profit plan, while backlog growth slows
Solv Energy, a builder of utility-scale solar and battery plants, bounced back on project profitability and cash flow while its contract backlog grew more slowly than revenue. Third-quarter revenue rose 65% from a year ago, and gross margin excluding stock pay recovered by two percentage points from the spring to 17.3% as maintenance work expanded. Chief executive George Hershman raised every full-year target, putting second-half profit well above what the company's own prior plan pointed to.
| Revenue | $1,242M +65% from a year ago |
|---|---|
| Gross margin, excluding stock pay | 17.3% up from 15.2% last quarter |
| Total backlog | $9.2B +37% from a year ago |
| Full-year revenue outlook | Raised $155M middle of the range: 64% growth |
⚖️ Verdict: 🟢 Bullish
The story got better because the spring margin drop and cash drain both reversed. Customer advance payments rose and lifted third-quarter operating cash flow to $131 million by our math, easing fears that material purchases would tie up cash all year. One caution: total backlog growth slowed to 37% from 44% last quarter, trailing revenue growth for a second straight period.
The question now is whether 2027 revenue growth must slow down to match the 37% pace of backlog growth, or if converting preliminary awards into signed contracts will keep construction growing faster. The backlog breakdown in the third-quarter filing and the initial 2027 outlook next quarter will tell.
🐂 Bull Case
Project Margins Rebounded and Lifted the Outlook
Solv Energy builds and maintains large solar and battery plants, and its gross margin — profit left after direct construction costs — had worried investors after dropping in the spring. In the third quarter, gross margin excluding non-cash stock pay rebounded by 2.1 percentage points from the prior quarter to 17.3%, beating the 15.6% to 16.7% second-half band implied by the old plan.
Top-line growth came from "both an increase in new construction activity and in existing infrastructure revenue", the company said, as power capacity under maintenance contracts passed 24 gigawatts. That rebound in maintenance work — which had shrunk in the second quarter — allowed chief executive George Hershman to raise the full-year outlook for a third time since the February listing.
What to watch: fourth-quarter gross margin excluding stock pay, which the updated full-year plan puts at 15.8% by our math. Holding above 16% would show that newer, larger solar projects are earning better margins as construction progresses past the halfway mark.
Customer Advances Restored Third-Quarter Cash Flow
During the first half of 2026, the solar contractor generated only $46 million in operating cash flow because it spent cash on materials and worked down advance payments from customers. By our math, operating cash flow jumped to $131.2 million in the third quarter alone, and free cash flow — cash left after buying equipment — reached $120.2 million, up 88% from a year ago.
Cash recovered because customers sent upfront deposits for new construction work, pushing contract liabilities up 25% from June to $322.8 million and eliminating the working-capital drain for the quarter. What to watch: fourth-quarter operating cash flow and supplier deposit notes in the full quarterly filing, because another drop in customer advances would turn cash generation negative again.
Small Acquisitions Expand Substation and Storage Skills
Solv uses its debt-free balance sheet to buy smaller specialists so its own crews can build high-voltage grid connections instead of hiring subcontractors. After closing California substation builder Roberson Waite Electric for $37.1 million in net cash in July, the power infrastructure group bought Texas-based ASB Energy Services on October 30 for $36.0 million in cash and about 377,000 shares.
ASB builds "substation foundations, civil construction and battery energy storage system infrastructure" for data centers and utilities, the company said. What to watch: how much revenue Roberson Waite and ASB contributed to the $155 million full-year revenue outlook raise when management discloses acquisition tables in the quarterly filing, as acquired sales can mask slower underlying project bookings.
🐻 Bear Case
Backlog Growth Slows Further Behind Revenue
Backlog is the total value of uncompleted construction and maintenance contracts, and bulls view big battery and 450-megawatt solar awards as the fuel for multi-year growth. Hershman said the $9.2 billion backlog and market demand "position us well as we look ahead to 2027".
The numbers tell a more cautious story, because backlog growth slowed for a third consecutive quarter even as current construction revenue stayed above 60%. By our math, the contractor won about $1.58 billion in gross new work during the quarter, leaving net backlog up just $340 million after burning through $1.24 billion in quarterly sales.
- Third-quarter backlog growth: up 37.3% from a year ago, down from 43.5% in the second quarter and 82.2% in the first
- Gap vs sales growth: backlog grew 27.6 percentage points slower than third-quarter revenue (+64.9%)
- Battery storage backlog: not disclosed in the release, after reaching $2.5 billion last quarter
What to watch: fourth-quarter ending backlog and the battery storage dollar figure in the upcoming filing. If backlog growth stays below 40% while quarterly revenue burns over $1.2 billion, revenue growth in 2027 must slow down toward the pace of new contract wins.
Pre-IPO Owners Collect Cash as Tax Debt Grows
Solv went public using an ownership structure that leaves pre-IPO private equity and executive owners holding partnership units and a tax receivable agreement, which pays them most of the company's future tax savings. In the third quarter, that future tax payout liability on the balance sheet climbed by $49.1 million to $289.8 million.
Meanwhile, the operating partnership paid another $19.0 million in cash distributions to its members during the quarter by our math, bringing nine-month member payouts to $203.4 million against $177.3 million in operating cash flow. What to watch: the schedule of future tax agreement payments in the quarterly filing, because those cash outflows will reduce cash available for public shareholders starting around 2028.
Risks this quarter didn't answer
Four standing policy, contract and execution risks received no updated numbers in the third-quarter earnings release because those details live in the quarterly filing and conference call.
- Signed contract share of backlog: last reported at 40% in June against 53% in unsigned preliminary awards; the filing's backlog table will show if customers kept signing final contracts.
- Polysilicon tariff exposure: no update on whether Section 232 import duties delayed customer solar panel deliveries on unsigned awards; call commentary will test this.
- Post-tax-credit demand cliff: current backlog qualifies for existing federal tax rules, and only 2027 bookings will show if developers build as much under stricter foreign-supply rules.
- Large-project execution: no update on average project size (~450 megawatts in Q2) or estimate adjustments in the release; Footnote 4 of the filing will show if maturing jobs released contingencies.

Bonus Shift Explains the Annual Gross Margin Drop
Reported gross margin fell 1.9 percentage points from a year ago to 17.8%, while overhead expenses (selling, general and administrative costs) dropped 1.7 points to 5.0% of revenue. That happened because Solv moved annual employee bonus costs from overhead into direct cost of revenue starting in 2026, and because third-quarter 2025 included a large repair job and "project performance and contingency release from later stage projects", leaving operating margin up 0.5 points at 11.4%.
💲 Other KPIs
Uncollected customer bills jumped 65.1% from June and have more than doubled from $269.0 million at the end of 2025. The increase outpaced third-quarter sequential revenue growth of 30.5%, tying up working capital as construction volume peaked.
Quarterly interest costs fell 87.3% from $13.7 million a year ago after the contractor used its February initial public offering proceeds to pay off $405.2 million in term debt. With interest income of $1.8 million, net interest was a slight credit for a second straight quarter.
Contract liabilities — cash billed to customers ahead of construction work performed — rose 25.0% from $258.2 million in June, reversing the second quarter's drop from $346.3 million. At 26.0% of quarterly revenue, advance billings remain a smaller share of sales than at the start of the year.
🔮 Guidance
Raised. The middle of the full-year sales plan moved up by $155 million to $4,075 million, or 63.6% growth for the year. By our math, that leaves $1,205 million for the fourth quarter — up 51.9% from a year ago, down from 64.9% growth in the third quarter. It is the second consecutive raise: +$0M in Q1, +$150M in Q2, +$155M in Q3.
Raised. The company lifted the middle of its full-year target by $35 million to $675 million, up 45.4% from 2025. By our math, the outlook leaves $190.9 million for the fourth quarter after $484.1 million in the first nine months.
Raised. Management tightened and lifted the range by 0.25 percentage points at the middle to 16.55%. Because the first nine months averaged 16.9%, the full-year plan points to about 15.8% in the fourth quarter by our math, down from 17.3% in the third quarter.
Raised. The target for operating profit before depreciation and one-offs rose $37.5 million at the middle to $532.5 million, or 55.9% annual growth. By our math, that leaves $149.6 million for the fourth quarter (+49.0% from a year ago). Third raise in three quarters: +$35M, +$50M, +$37.5M.
Raised. The full-year margin plan moved up 0.45 percentage points at the middle to 13.05%, compared with 13.7% in 2025. After delivering 13.3% across the first nine months and 13.9% in the third quarter, the outlook implies a fourth-quarter margin of 12.4% by our math on seasonally lower winter construction.
❓ Key Questions
Did the signed share of backlog hold near 40%?
The earnings release gave total backlog of $9.2 billion but omitted the split between signed contracts and preliminary awards (40% vs 53% in June) as well as battery storage dollars ($2.5 billion in June).
How much did RWE and ASB add to the outlook?
Solv closed Roberson Waite on July 1 and ASB Energy Services on October 30, and raised its full-year revenue outlook by $155 million without stating how much came from the two acquired businesses.
Why did accounts receivable jump 65% in one quarter?
Uncollected customer bills rose by $256 million from June to $648.5 million, far outpacing the 31% sequential increase in quarterly revenue.
Are solar panel tariffs delaying unsigned customer awards?
Over half of backlog in June sat in preliminary agreements where developers were still locking in equipment, and the release gave no update on Section 232 polysilicon tariff impacts.
