M&A activity snapshot
General contractors are bought less often, and for less, than the specialty trades that work under them. Capstone counted 366 subcontractor deals out of 562 construction services transactions in 2025, so most construction M&A happens below the general contractor. Public-market pricing shows why: Tutor Perini, the one public U.S. general contractor in Capstone's comparison set, traded at 0.7x revenue in August 2025, with its EBITDA multiple not meaningful because trailing EBITDA was near zero.
This page covers commercial, institutional, and multifamily general contracting and construction management (NAICS 236220). Residential homebuilders are a separate market.
GC deals still happen, mostly between builders. Moss, a national construction manager, acquired Tampa-based Ellison Construction in December 2025. Bulley & Andrews acquired interiors contractor ICG in April 2026. Few of these deals disclose prices.
Who is buying
Larger construction managers. National and super-regional builders buy local GCs to enter a market with an established client list. Moss described the Ellison deal as joining two family-founded firms at a time when scale and local credibility increasingly determine who wins major development work.
Japanese builders. Japan's large contractors are steady buyers of U.S. GCs. Obayashi's Webcor bought Phoenix construction manager GCON, saying GCON would use Webcor's and Obayashi's financial strength to pursue larger projects. Shimizu bought 51% of New York interiors contractor Cross Management in 2025, and Charlotte-based Rodgers Builders joined Kajima USA in 2024.
Family-of-companies groups. STO Building Group grew by merging regional builders that keep their own brands. When Layton joined in 2019, about 100 senior executives and family members became shareholders in STO's parent organization.
Multifamily renovation platforms. Renovation-focused GCs attract a different buyer. The Byng Group bought RC Legnini to strengthen its position as a renovation partner for multifamily housing providers in the Mid-Atlantic and Northeast.
What buyers look for
Backlog in growing building types. Data centers dominate. ABC members working on a data-center project reported 11.0 months of backlog against 7.8 months for those who were not, and ABC noted that those projects favor the largest contractors. AGC's 2026 survey found contractors' highest net optimism, 57 percent, for data centers, and expects data centers, power facilities, and healthcare to drive much of the private market in 2026. Census shows private office construction up 29.8% year over year in August 2026, while manufacturing fell 19.8%. Data centers, which Census counts inside office, rose 73.2% over the same period.
Bonding that survives the sale. A GC's capacity to bid depends on its surety program, and that program rests on personal guarantees. Sureties typically require the individuals who control the company and their spouses to sign the indemnity agreement. One public company's indemnity agreement treats any change in control without the surety's prior written consent as a default. Buyers need a surety ready to back the combined company.
Project-level margin and fee discipline. GC margins are thin, so buyers look at fee, general conditions, and change-order recovery by project. Tutor Perini's near-zero trailing EBITDA in Capstone's comp set, alongside a record $21.6 billion backlog, shows that backlog without margin does not support a high multiple.
Owner and client relationships. A GC's real asset is repeat work with developers, institutions, and owners. Buyers check how much backlog comes from negotiated or repeat clients versus hard-bid public work.
What makes a strong company
A general contractor that draws strategic interest typically has:
- Backlog of at least a year, weighted to building types still growing in the Census data, such as data centers and healthcare.
- Repeat or negotiated work with a group of owners and developers, not one anchor client.
- Consistent project-level margins, with documented change-order and claims history.
- A surety program with room to grow, and principals prepared to work with the buyer's surety on the indemnity transition.
- Project executives and superintendents who own client relationships, so the business does not depend on the founder.
- Self-perform capability in at least one trade, which improves schedule control and margin.
Valuation and deal structure
Reliable private-market EBITDA multiples for general contractors do not exist in public sources. The best public proxy, Tutor Perini at 0.7x revenue with an EBITDA multiple that was not meaningful, shows how thin margins limit GC valuations. Capstone's construction-wide averages of 10.6x EV/EBITDA for PE buyers and 7.5x for strategics from 2018 to 2025 are pulled up by specialty trades and should not be applied to a GC.
Structure matters as much as price. Partial sales are common: Shimizu took 51% of Cross Management, and Layton's owners took shares in STO's parent organization rather than cash alone. Expect the surety transition, retention of key project executives, and treatment of in-progress jobs to be negotiated alongside price. To check where your numbers sit, use the valuation tool.
Outlook
Expect GC deals to keep tracking backlog in data centers, power, and healthcare. Builders with that exposure will draw interest from larger construction managers and foreign strategics; GCs tied to private manufacturing or commercial work will find a thinner buyer pool while those categories decline in the Census data.
Japanese builders' purchases of Webcor-GCON, Cross Management, and Rodgers Builders suggest continued foreign appetite for U.S. regional GCs with strong local client lists.
