Limbach books $311.2M in a quarter as two acquisitions start to pay

For every dollar Limbach billed between July and September, it signed up $1.40 of new work. The building systems contractor reported third-quarter results on 3 November: record revenue of $230.5M, up 24.9% from $184.6M, and bookings of $311.2M.

The numbers

Limbach splits its business in two. Owner-direct relationships (ODR), where it works straight for building owners on repair, retrofit and service, is the part it wants to grow. That segment brought in $150.7M, up 6.6%, and made up 65.4% of revenue. General contractor relationships (GCR), the more traditional subcontract work, jumped 84.7% to $79.8M.

Strip out acquisitions and total revenue still rose 14.4%. Organic ODR growth was a modest 2.2%, but it was positive. President and CEO Michael McCann described the quarter as showing "a return to organic growth in our owner-direct business", and said project timing issues flagged earlier in the year are beginning to ease.

Adjusted EBITDA hit a record $27.4M, up 25.9%. Gross margin slipped to 23.4% from 24.2%, and the company says the businesses it has bought run below its historical margins, a gap it aims to close over two to three years. Net income was $9.5M.

What the deals added

Both acquisitions closed in the quarter and together contributed $19.3M of revenue. 1901, a union MEP contractor in Madison, Wisconsin, cost $63M and brings about 450 employees, more than 350 of them in the field. Limbach expects it to add about $140M of revenue in 2027. CYMCOR is smaller but pointed: according to Investing.com's summary of the earnings presentation, it takes Limbach's data centre work into program management, commissioning oversight and consulting.

The same presentation featured six data centre campus projects, from Atlanta to San Antonio, ranging from 177 MW to more than 280 MW of critical capacity. McCann said the two deals add opportunities in data centres, life sciences and advanced manufacturing.

Guidance

Limbach held its 2026 revenue range at $760M to $790M and adjusted EBITDA at $78M to $84M, but now expects to land at or near the top of both.

The bigger picture

Limbach is a fraction of the size of EMCOR, which booked $5.54bn of revenue in its own third quarter, and its strategy is different: less new-build volume, more recurring work for owners who already know them. What this quarter shows is that even the owner-focused players are buying their way into data centre capability, and that they are buying people as much as revenue. A 125-year-old Wisconsin contractor with more than 350 field staff is a workforce deal as much as a market entry.

What it means for hiring

Two acquisitions in one quarter usually means integration work: we would expect demand for operations and project leaders who can bring new branches onto common systems, estimating and safety standards.
CYMCOR's commissioning and program management focus points to where mid-size contractors want to grow. In our view, commissioning leads with data centre experience are among the scarcest profiles in mechanical contracting right now.
Owner-direct growth depends on service account managers and service technicians who can build relationships with facility teams. Those roles tend to be harder to fill than project-side hires.
