Legence (LGN) Q3 2026 earnings review

Legence lifts profit margins and raises 2026 targets

Legence earned its highest profit margin on record while its underlying sales growth cooled from the first half's blistering pace. The designer and installer of heating, cooling and piping systems for data centers and buildings grew sales from businesses owned a year ago by 40% (85% including the January purchase of Bowers), down from 60% last quarter. Chief executive Jeff Sprau credited factory pre-fabrication for lifting the Adjusted EBITDA margin to 13.5%, raised the 2026 plan a fourth time, and set an initial 2027 outlook that points to about 11% revenue growth by our math.

Initial 2027 revenue outlook$5.3–5.6B middle of the range: 11.5% growth over 2026 plan

⚖️ Verdict: 🟢 Bullish

The story got better because installation margins expanded after two flat quarters and management's new fourth-quarter plan eliminated the year-end dip its prior full-year outlook pointed to. Lower debt also allowed a $150 million buyback plan and a small Texas acquisition serving semiconductor plants. One caution: the Engineering and Consulting division shrank 6% from a year ago, and contract liabilities fell for a second straight quarter as project execution outpaced upfront customer billings.

The question now is whether the 11% revenue growth in the 2027 plan reflects a genuine data-center slowdown or the same cautious target-setting that produced four straight quarterly beats. Either the data-center construction boom is cooling after customers pulled projects forward in the first half, or management is building a wide buffer for its first year lapping the Bowers acquisition. The underlying backlog growth figure on the conference call and first-quarter 2027 order intake will settle it.

🐂 Bull Case

🟢🟢 strengthening MARGIN

Installation Margins Expanded and Lifted Company Profit

"Our team continues to deliver exceptional project execution, which along with an increasing mix of fabrication work, contributed to the delivery of the highest Adjusted EBITDA margin in company history," chief executive Jeff Sprau said. Legence designs and installs heating, cooling and piping systems for buildings, and it pre-builds components in its own fabrication shops to earn higher margins.

The Installation and Maintenance division drove the quarter on "strong demand for our Installation & Fabrication services, primarily from data centers & technology clients". Division gross margin excluding one-offs rose to 18.0%, up from 16.6% a year ago and 16.1% last quarter, because of "higher project margins in our Installation & Fabrication service line and greater economies of scale in customer fulfillment support costs".

  • Installation and Maintenance sales excluding Bowers: up 58.9% from a year ago (124.0% reported)
  • Selling, general and administrative overhead: 5.4% of revenue, down 6.8 percentage points from a year ago
  • Adjusted EBITDA (profit before interest, taxes, depreciation and one-offs): $177.0 million, or 13.5% of sales

What to watch: the share of division sales coming from fabrication-only work and the data-center revenue share on the conference call. The release omitted both figures, and rising numbers would confirm that factory pre-building rather than one-off project closeouts drove the 18.0% margin.

New Q4 Plan Beats What the Old Outlook Implied

Three months ago, Legence's full-year outlook pointed to a fourth-quarter slowdown, with revenue of about $1.20 billion and Adjusted EBITDA near $147 million at the middle of the implied ranges by our math. Today the mechanical contractor set its explicit fourth-quarter plan at $1.26–1.30 billion for sales and $160–170 million for Adjusted EBITDA, well above what the earlier full-year plan pointed to.

That upward reset shows the earlier outlook was cautious, which matches a record of beating its quarterly revenue target four quarters in a row. Still, a cautious prior plan does not settle whether customer orders are slowing after the second quarter's schedule pull-forwards.

What to watch: fourth-quarter revenue against the $1.30 billion top of the new range. A fifth consecutive beat above the top of the range would show that the 2027 outlook also starts with a cautious buffer.

🟢 strengthening CAPITAL ALLOCATION

Lower Debt Ratio Opens Room for Buybacks and Texas Deal

Strong cash generation over the past year cut Legence's net debt to 1.3 times its trailing 12-month Adjusted EBITDA, down from 2.4 times a year ago and 1.6 times last quarter (1.2 times when including a full year of Bowers). Critics worry that falling debt will tempt management to overpay for large acquisitions near the top of the construction cycle, but this quarter's moves stayed small.

On November 1, the group bought Central Texas Industrial Contractors (CTI), an Austin mechanical contractor "supporting mission-critical infrastructure, with a strong presence in the semiconductor end market in central Texas". Sprau said the deal is "creating an ideal platform to expand customer support across this high-growth region", and CTI brings about $40 million in yearly sales while the board also authorized a $150 million stock buyback.

What to watch: cash spent on share repurchases versus new acquisitions in the fourth-quarter report. Buying back shares rather than chasing another large deal would ease concerns about aggressive spending at the top of the cycle.

🐻 Bear Case

🔴🔴 strengthening GROWTH contradicts narrative

Underlying Growth Slowed and the 2027 Plan Steps Down

Legence highlighted an 85.1% jump in total sales to $1.31 billion, which includes $322.7 million from The Bowers Group, a large contractor it bought in January 2026. Sales from businesses owned a year ago grew 39.5%, stepping down from 60.0% in the second quarter and 57.1% in the first quarter.

The company's first outlook for 2027 points to a much slower pace once the Bowers acquisition enters the comparison base in January. Management forecasts 2027 revenue of $5.3–5.6 billion, which by our math represents 11.5% growth at the middle of the range over the revised 2026 plan.

Order intake is also running cooler than last year: the book-to-bill ratio, which measures new project awards against fixed-price revenue billed, was 1.2 times for a third straight quarter, down from 1.5 times a year ago. Because the second quarter benefited from projects pulled forward at the request of customers, the slower underlying rate and 11.5% outlook test how fast data-center construction can keep expanding.

What to watch: first-quarter 2027 revenue outlook when fourth-quarter results arrive. That quarter is the first clean year-over-year comparison that includes Bowers in both periods, so it will show the true underlying growth rate.

Engineering Revenue Shrank even as Segment Margins Rose

Legence's Engineering and Consulting division designs building systems and manages construction programs, and it suffered $41.1 million of asset write-downs in its sustainability consulting unit last quarter. In the third quarter, the division recorded no new write-downs and lifted its gross margin excluding one-offs by 0.5 percentage points to 33.3%, reversing three quarters of margin pressure.

However, the margin gain came only because the lower-margin Program and Project Management line shrank 10.3% from a year ago, pulling total division revenue down 5.8% to $199.9 million. The company cited "a decline in Program & Project Management services and modestly lower Engineering & Design revenue, primarily from education clients", showing that consulting demand remains weak despite a 32.6% rise in division backlog.

What to watch: Engineering and Consulting revenue in the fourth quarter. A return to revenue growth would show the 32.6% backlog increase is finally converting into billed consulting work.

🔴 persistent DISCLOSURE

Risks this quarter didn't answer

Four standing concerns from the second quarter cannot be read from the earnings release and await the quarterly filing or conference call.

  • Underlying backlog growth: the release reports total backlog up 92.5% (43.6% by our math stripping Bowers' $1.5 billion opening backlog), but omits the exact underlying figure management gave on prior calls.
  • Single-customer concentration: one installation customer accounted for 17.2% of total revenue in the second quarter; the release does not state that customer's third-quarter share.
  • Fixed-price project risk: surety-bonded backlog on large fixed-price contracts reached $1.45 billion at mid-year, and the updated balance lives in the filing footnotes.
  • Sponsor tax payments: the Tax Receivable Agreement liability to pre-IPO owners held at $342.7 million, and future cash payouts depend on sponsor share exchanges.

Stock-Based Pay Reversal Swung Reported Profit

Legence's reported net profit swung to $133.9 million ($89.6 million attributable to common shareholders, or $1.15 a share) after a $27.8 million attributable loss last quarter. Much of the swing came from legacy pre-IPO profit-interest units paid for by outside entities: revaluing those units created a $35.3 million accounting benefit this quarter after a $73.9 million charge in the second quarter, which Legence strips out of its non-GAAP results.

Backlog and awarded contracts (26Q3) $5.90 billion
⇘ decelerating

Total contracted backlog and awarded projects rose 92.5% from a year ago and added $229 million from last quarter, down from a $289 million sequential gain in the second quarter. Stripping out the $1.5 billion acquired with Bowers at the start of the year, backlog and awards grew 43.6% from a year ago by our math on a 1.2x book-to-bill ratio.

Contract assets, net (26Q3) $513.3 million
⇗ accelerating

Contract assets — revenue recognized on projects before Legence bills the customer — nearly doubled from $259.9 million at year-end and consumed $184.8 million of operating cash over the first nine months. Meanwhile, contract liabilities (upfront cash collected from customers before work is performed) fell 6.9% from the second quarter to $482.0 million, a second straight quarterly drop.

Free cash flow (26Q3) $64.2 million
⇘ decelerating

By our math, third-quarter free cash flow (operating cash flow of $82.5 million minus $18.3 million of equipment purchases, derived by subtracting first-half totals from nine-month figures) fell 29.0% from $90.4 million a year ago. Working-capital timing on unbilled contract assets and higher spending to outfit fabrication shops weighed on third-quarter cash conversion despite higher profit.

🔮 Guidance

Q4 2026 Revenue $1.26–1.30 billion
⇘ decelerating

New. The plan calls for $1.28 billion at the middle of the range, up 73.5% from a year ago (including Bowers and $6–8 million from CTI) and down 2.3% from the third quarter. Legence has beaten its quarterly revenue midpoint by an average of 13.2% over the past four quarters; if the pattern holds, fourth-quarter sales would reach about $1.45 billion by our math.

Q4 2026 Adjusted EBITDA (excluding one-offs) $160–170 million
⇘ decelerating

New. The middle of the range ($165 million) is up 89.7% from a year ago and down 6.8% from the third quarter's record $177.0 million. That implies an Adjusted EBITDA margin of 12.9% at the middle of the range, down 0.6 percentage points from the third quarter on winter seasonality.

FY2026 Revenue $4.87–4.91 billion
🠅 raised from $4.70–4.80 billion
⇗ accelerating

Raised. Management lifted the middle of the full-year range by $140 million, to 91.7% growth over 2025. This is the fourth raise across five quarters, and the latest increase is the smallest in the sequence: +$1,050 million (when Bowers was added), +$400 million, +$550 million, and +$140 million.

FY2026 Adjusted EBITDA (excluding one-offs) $610–620 million
🠅 raised from $565–585 million
⇗ accelerating

Raised. The middle of the range moved up $40 million to $615 million, more than double 2025's $298.8 million. Across five consecutive updates, the building-systems contractor has raised the middle of its 2026 profit target by +$110 million, +$65 million, +$95 million, and +$40 million.

FY2027 Revenue $5.30–5.60 billion
⇘ decelerating

New. The initial 2027 plan points to 11.5% growth at the middle of the range ($5.45 billion) compared with the revised 2026 midpoint. Because Legence closed the Bowers acquisition on January 2, 2026, the 2027 outlook compares against a full year of Bowers revenue and includes about $40 million expected from the newly acquired CTI business.

FY2027 Adjusted EBITDA (excluding one-offs) $690–730 million
⇘ decelerating

New. At the $710 million middle of the range, profit excluding one-offs grows 15.4% over the 2026 plan midpoint. By our math, that embeds a 13.0% full-year Adjusted EBITDA margin, up 0.4 percentage points from the 12.6% implied for full-year 2026.

❓ Key Questions

What was underlying backlog growth excluding acquisitions at quarter-end?

On prior calls management stated that underlying backlog and awarded contracts grew 36% in the first quarter and 35% in the second. Because the release omits the third-quarter rate, investors cannot tell whether order growth kept falling behind the 39.5% underlying sales pace.

Did the fabrication-only share of installation sales rise above 20%?

Chief executive Jeff Sprau credited an increasing mix of fabrication work for the record 13.5% profit margin. For the prior three quarters, third-party fabrication held in the low-20% range of segment sales, so quantifying the new share would show how much margin room remains.

How much of the 2027 revenue plan is already in signed backlog?

The 2027 outlook calls for 11.5% revenue growth after 39.5% underlying growth in the third quarter. Knowing what percentage of the $5.90 billion backlog converts in 2027 versus 2028 will clarify whether the 11.5% target reflects slowing data-center demand or routine conservatism.

What share of revenue and backlog comes from your largest customer?

A single Installation and Maintenance customer grew to 17.2% of revenue in the second quarter, up from 5.7% a year earlier. Any pause in that client's build schedule would hit both factory utilization and the 2027 outlook.
