Construction and engineering M&A held steady in Q1 2025, with 214 announced transactions. Strategic acquirers with strong balance sheets retained the edge over financial buyers, who remained selective as they tracked interest rates and inflation. Our Q1 spotlight: electrical contracting, where private equity activity, generational ownership transitions, and demand for integrated MEP solutions are pushing the vertical into platform-formation mode.
Industry overview
Engineering and construction spans design, procurement, construction, and ongoing maintenance, with architects, engineers, materials and equipment suppliers, general contractors, and specialty subcontractors all in the value chain. The industry plays a foundational role across three major categories, each with distinct delivery methods and capital sources, but all dependent on core construction expertise, supply chains, and labor capacity.
Residential construction
Single-family homes, townhomes, and multi-family developments. Activity is heavily influenced by interest rates, demographics, affordability, and local permitting. Large homebuilders often self-perform or manage through national networks, supported by a deep bench of specialty subcontractors in framing, roofing, HVAC, and more. Modular and prefabricated construction is gaining traction as developers seek to reduce cycle times and costs.
Nonresidential building construction
Offices, hotels, hospitals, schools, warehouses, data centers, retail stores, and manufacturing plants. Projects are typically larger and more technically complex, requiring coordination across architects, engineers, GCs, and multiple specialty trades. Demand for energy efficiency, smart building systems, and LEED practices is rising. Design-build and construction management-at-risk are increasingly preferred delivery models.
Infrastructure (nonbuilding) construction
Roads, bridges, highways, airports, rail, water treatment, electric transmission, and broadband. Long-duration projects funded by public agencies or public-private partnerships. Heavy civil contractors and engineering firms typically work under multi-year contracts. Federal legislation including the IIJA, IRA, and CHIPS Acts is injecting substantial capital, fueling demand for skilled labor and M&A.
M&A outlook
Activity in the sector held steady quarter-over-quarter. Many financial buyers remain on the sidelines, watching interest rates and inflation given the direct impact on borrowing costs. Strategic acquirers with strong balance sheets have an advantage in this environment, less exposed to capital-market volatility and able to win deals against financial buyers constrained by required fund returns.
Federal programs such as the IIJA and IRA have put a significant amount of civil infrastructure construction in motion, making these firms attractive investment opportunities. Residential contractors focused on maintenance and renovation, such as HVAC and plumbing, continue to perform well in the M&A market, while new-build-focused residential contractors are seeing softer demand as affordability remains an issue. Nonresidential building contractors are likely to become more attractive as reshoring continues.
Strategic acquirers carry several advantages: they often fund transactions with minimal debt using strong cash positions, can identify synergies that push valuations higher, and understand industry-specific risks better than generalist PE funds, which lets them move quickly. In Q1 2025, transactions split roughly 55% strategic and 45% private equity by buyer type.
Featured vertical: electrical contracting
While overall construction services activity moderated in 2024 amid macro uncertainty and rising financing costs, electrical contracting has remained active. Strong private equity interest, generational ownership transitions, and demand for integrated MEP solutions have kept the vertical busy. Platform formation and add-on activity are expected to accelerate as strategic buyers and sponsors seek scale, recurring revenue, and market specialization.
Integrated service platform expansion
Buyers are acquiring firms with complementary electrical, mechanical, and low-voltage capabilities to build turnkey MEP platforms, improve coordination on complex projects, and capture more wallet share per customer.
Geographic and vertical market growth
Strategic and financial acquirers are targeting firms in underserved geographies and high-growth end markets such as healthcare, data centers, and infrastructure. The aim is footprint, pipeline diversification, and entry into less cyclical sectors.
Succession and talent-driven consolidation
Many deals are catalyzed by founder retirements. Buyers use M&A to secure tenured leadership, skilled labor, and institutional customer relationships in a market with acute workforce constraints.
Recurring revenue and service model expansion
Acquirers are prioritizing targets with maintenance, retrofit, and emergency service offerings. The goal is to reduce project-based revenue volatility, enhance margin, and drive long-term customer stickiness.
Electrical contracting valuation multiples
Across PE-backed electrical contracting transactions (all years), EBITDA multiples scale with size: 5.0x at $10M to $25M (12.1% EBITDA margin, N=3), 6.4x at $25M to $50M (19.6% margin, N=7), and 7.5x at $50M to $250M (13.0% margin, N=6). The blended average is 6.6x at a 15.7% EBITDA margin across 16 transactions. Larger, better-positioned platforms continue to command premiums.

Case study: Braemont Capital and the Loenbro platform
In February 2024, Braemont Capital, a relationship-driven investment firm focused on companies at growth inflection points, acquired Loenbro from Tailwind Capital in one of Braemont's largest investments. Loenbro, based in Westminster, Colorado, specializes in highly technical services, including electrical, mechanical, structural, instrumentation, inspection, and related maintenance, for data centers, infrastructure, and diversified industrial markets. The deal was designed to accelerate Loenbro's growth through organic expansion and M&A while preserving its commitment to quality, safety, and customer-first culture.
A flurry of follow-on M&A
January 2025, Loenbro acquired Arizona-based Revolution Industrial, broadening its technical service suite across electrical, mechanical, structural, soft-craft, and inspection in the Southwest.
April 2025, Loenbro acquired Nevada-based Stewart Electric, focused on mission-critical data center electrical work, strengthening Loenbro's data center capabilities, geographic reach, and operational excellence focus.
July 2025, Loenbro acquired Colorado-based Weifield Group, expanding electrical services across the Mountain West, Texas, and Tennessee, with strength in data centers, semiconductors, and industrial markets.
Braemont's strategy with Loenbro illustrates a clear focus on building an electrical services platform and targeting mission-critical infrastructure. Revolution added industrial services, Stewart added data center electrical, and Weifield added regional electrical capabilities. Together, the moves position Loenbro to serve high-growth sectors including data centers, semiconductors, and industrial facilities.
Engagement spotlight: Project Power
Carleton McKenna was engaged by a regional electrical contracting company providing critical services to industrial, commercial, and residential customers. The business had strong brand equity through an exceptional regional reputation and a history of recurring project work, but like many contractors, it faced familiar challenges.
Challenges going in
Labor dependency: heavy reliance on a skilled technician base in a tight market.
Customer concentration: top accounts represented a meaningful share of revenue, creating perceived risk.
Cyclicality and backlog: project-based revenue streams raised questions about earnings durability.
Valuation expectations: shareholders wanted a premium outcome despite industry headwinds.
Process and approach
Reframing risk: highlighting recurring service and maintenance work and mission-critical project history to address cyclicality concerns.
Tailored buyer outreach: prioritizing strategic and financial sponsors already investing in infrastructure and technical services platforms.
Active diligence management: anticipating buyer questions on workforce retention, backlog stability, and safety metrics, with data prepared in advance.
Narrative building: emphasizing cultural alignment and growth runway into adjacent geographies and verticals.
Outcome
The company reached agreement with a growth-oriented investment group with deep experience in technical services. The buyer was drawn to the platform potential, regional brand, and skilled workforce.
The partnership delivered a favorable valuation that met shareholder expectations, commitment to employee growth and retention, and resources for expansion into new markets and services.
Residential, nonresidential, and nonbuilding trends
Residential dynamics in Q1 mirrored what we covered in the Q2 update: housing starts have stabilized at lower but steady levels following the 2022 declines tied to mortgage rate hikes; rates remain near 7% with limited near-term relief; ABC estimates the industry needs roughly 439,000 net new workers in 2025; and multi-family construction continues to absorb demand from would-be homebuyers priced out of ownership.
Nonresidential building activity continues to be shaped by three forces. Hybrid work has fundamentally reduced demand for new office space, with vacancy above 20% in top metros and demand shifting to renovation and adaptive reuse. Factory construction spending is at record levels, with CHIPS and IRA driving manufacturing construction more than double its 2022 level. Healthcare construction remains resilient, supported by aging demographics, outpatient demand, and aging facilities; the average U.S. public school building is 49 years old, with over 40% of school districts needing HVAC upgrades for at least half of their schools.
Nonbuilding (infrastructure) is in a moment of policy friction. Strong momentum from the IIJA and IRA is colliding with administration efforts to defund or delay green energy programs. In the short term, projects continue, albeit with more administrative friction. In the medium term, much depends on the FY26 federal budget and the 2026 midterms. State mandates, corporate demand, and private investment should sustain a baseline of activity even if federal leadership shifts direction. Environmental and climate resilience work is less politically vulnerable, as it addresses bipartisan concerns around disaster readiness and insurance risk.
