Boyne Capital Exits McKee Utility Contractors to MasTec

Boyne Capital Partners has successfully exited its investment in McKee Utility Contractors Inc., selling the Michigan-based utility infrastructure specialist to MasTec Inc. (NYSE: MTZ), one of North America's largest infrastructure construction companies. The transaction, announced January 29, 2025, represents a strategic platform acquisition for MasTec as it deepens its presence in the Midwest utility market and underscores continued private equity interest in the essential infrastructure sector.

Financial terms were not disclosed, but the deal marks a successful exit for Boyne Capital, which partnered with McKee Utility to support its growth trajectory in underground utility construction and infrastructure services. The transaction adds meaningful scale to MasTec's existing utility operations and positions the combined entity to capitalize on surging demand for grid modernization and electrification infrastructure.

The McKee Utility acquisition fits squarely within MasTec's long-standing consolidation strategy in the fragmented utility construction sector. With approximately $15 billion in annual revenue, MasTec has built its infrastructure empire through disciplined acquisitions of regional specialists, integrating them into a national platform capable of serving utilities, telecommunications providers, and energy companies across North America.

McKee Utility, headquartered in Jackson, Michigan, brings specialized expertise in underground utility construction, including electric distribution, gas distribution, telecommunications infrastructure, and water/wastewater systems. The company has built a reputation for complex underground installations and has cultivated long-standing relationships with major utilities across Michigan and the broader Midwest region.

For MasTec, the acquisition strengthens its geographic density in a region experiencing significant utility infrastructure investment. Michigan utilities are allocating billions toward grid hardening, renewable energy integration, and replacement of aging infrastructure—creating a multi-year tailwind for specialized contractors like McKee.

Boyne Capital Partners, a private equity firm with approximately $1.5 billion in assets under management, focuses on control investments in lower middle-market companies across business services, niche manufacturing, and value-added distribution sectors. The firm, based in Harbor Springs, Michigan, typically targets companies with $10 million to $75 million in revenue.

While Boyne Capital did not disclose the specifics of its investment thesis or hold period, the McKee Utility partnership likely centered on operational improvements, customer diversification, safety protocol enhancement, and geographic expansion—standard value creation levers in the utility construction subsector.

The successful exit to a strategic acquirer like MasTec validates Boyne's thesis that well-managed, regional utility contractors with strong safety records and customer relationships command premium valuations from consolidators seeking to expand their footprint.

MasTec has long pursued a strategy of acquiring regional utility contractors to build density in key markets and cross-sell capabilities across its service lines. The company operates through five primary segments: Communications, Clean Energy and Infrastructure, Oil and Gas, Power Delivery, and Other.

The McKee acquisition bolsters MasTec's Power Delivery segment, which focuses on electrical transmission and distribution infrastructure. This segment has experienced robust growth driven by utility spending on grid modernization, storm hardening, and interconnection of renewable energy projects.

According to Edison Electric Institute, U.S. investor-owned utilities are projected to invest more than $150 billion annually in transmission and distribution infrastructure through 2030. This sustained capital expenditure creates a favorable environment for specialty contractors with established utility relationships and proven execution capabilities.

MasTec's integration playbook typically involves retaining local management, leveraging shared back-office functions, and cross-selling capabilities to the acquired company's customer base. McKee's employees will benefit from MasTec's training programs, safety protocols, and career advancement opportunities within a larger organization.

The McKee Utility exit reflects sustained private equity interest in essential infrastructure businesses, particularly those serving regulated utilities with predictable demand and long-term contract visibility. The sector has proven remarkably resilient through economic cycles, as utility capital programs are driven by regulatory mandates and safety considerations rather than discretionary spending.

Private equity firms have increasingly targeted utility contractors, communications infrastructure companies, and renewable energy service providers as infrastructure investment themes gain prominence. These businesses typically feature recurring revenue, strong cash flow generation, and fragmented competitive landscapes conducive to buy-and-build strategies.

The utility construction sector has witnessed significant M&A activity over the past 24 months, with both strategic and financial buyers pursuing consolidation opportunities:

Strategic acquirers like MasTec, Quanta Services, and MYR Group have been particularly active, as they seek to densify regional coverage and expand service capabilities. These consolidators typically pay premium multiples for well-positioned assets with strong customer relationships and safety performance.

While the parties did not disclose financial terms, utility construction businesses with McKee's profile typically command valuations in the 8-12x EBITDA range when acquired by strategic buyers, with premiums for companies demonstrating strong safety records, diversified customer bases, and specialized capabilities.

Several factors influence valuations in this sector:

Customer Concentration: Companies serving multiple utilities across diverse geographies command higher multiples than those dependent on a single customer relationship. Geographic density in high-growth markets further enhances value.

Safety Performance: Total Recordable Incident Rate (TRIR) and Experience Modification Rate (EMR) are critical metrics. Superior safety performance reduces insurance costs, improves workforce retention, and enhances qualification for larger projects.

Backlog Quality: Long-term master service agreements with utilities provide revenue visibility and reduce business development risk. McKee's established relationships with Michigan utilities likely contributed significantly to its attractiveness.

Specialized Capabilities: Underground utility construction requires specialized equipment, technical expertise, and certifications. Companies with differentiated capabilities in complex underground work command premium valuations.

McKee Utility's Michigan base positions the combined entity well to serve major utilities including DTE Energy and Consumers Energy, both of which have announced multi-billion-dollar infrastructure investment programs through 2030.

DTE Energy's distribution investment plan includes $3 billion for grid modernization, underground cable replacement, and storm hardening over the next five years. Consumers Energy has similarly committed $7 billion to infrastructure improvements, with emphasis on renewable energy integration and system reliability.

Michigan's aging utility infrastructure presents both challenges and opportunities. Much of the state's electric distribution network was built in the 1960s and 1970s, with components now reaching end-of-life. Utilities face regulatory pressure to improve reliability metrics while simultaneously supporting electrification initiatives and renewable energy mandates.

The state's renewable energy standard requires utilities to generate 15% of electricity from renewable sources by 2025, with momentum building toward more aggressive targets. This transition necessitates significant distribution system upgrades to accommodate distributed generation and bidirectional power flows.

MasTec's track record suggests McKee Utility will maintain its brand identity and local management team while benefiting from the parent company's financial resources, safety programs, and cross-selling opportunities. The integration typically unfolds over 12-18 months, with back-office functions consolidated while customer-facing operations remain largely unchanged.

For McKee's workforce, the transaction provides access to MasTec's training programs, career development pathways, and expanded project opportunities. The company's employees will join a platform with approximately 40,000 workers nationwide, creating advancement opportunities that standalone regional contractors cannot match.

The transaction also positions MasTec to pursue larger, more complex projects in the Midwest region. Utilities increasingly prefer working with contractors capable of self-performing multiple scopes of work, from engineering and design through construction and commissioning. MasTec's expanded capabilities in Michigan enable the company to compete for comprehensive project packages.

The McKee Utility transaction signals continued consolidation momentum in the utility construction sector, with both strategic and financial buyers competing for quality assets. For private equity firms holding similar platforms, the successful exit validates investment theses and may accelerate exit processes.

Strategic acquirers retain significant dry powder for additional acquisitions. MasTec ended its most recent quarter with approximately $700 million in available liquidity, positioning the company for further bolt-on acquisitions. Quanta Services and other competitors similarly maintain balance sheet capacity for accretive transactions.

For owners of regional utility contractors, the transaction environment remains favorable. Strategic buyers are paying premium multiples for businesses with strong safety records, diverse customer relationships, and specialized capabilities. Private equity firms continue raising infrastructure-focused funds, creating competition for quality assets and supporting valuations.

The infrastructure investment cycle shows no signs of slowing. Federal funding from the Infrastructure Investment and Jobs Act continues flowing to utilities, while state renewable energy mandates drive incremental spending on distribution system upgrades. Climate resilience initiatives further support sustained demand for utility construction services.

Boyne Capital's exit of McKee Utility Contractors to MasTec represents a well-timed transaction that capitalizes on strong strategic interest in utility infrastructure businesses. The deal provides MasTec with enhanced Midwest capabilities precisely as utilities accelerate infrastructure investment programs, while delivering Boyne Capital a successful exit to a premium strategic acquirer.

For the utility construction sector, the transaction underscores the ongoing consolidation trend as regional specialists join national platforms with the financial resources and operational scale to serve utilities' evolving needs. As grid modernization, renewable integration, and infrastructure replacement programs gain momentum, well-positioned contractors will continue commanding premium valuations from both strategic and financial buyers.

The McKee Utility acquisition marks another chapter in MasTec's disciplined growth strategy, reinforcing the company's position as a leading infrastructure construction platform. For Boyne Capital, the successful exit validates the firm's focus on essential infrastructure businesses serving non-discretionary end markets—a theme that should continue resonating with private equity investors navigating uncertain macroeconomic conditions.
