Clearlake Acquires Qualus Grid Platform in Power Services Push

Clearlake Capital Group has agreed to acquire Qualus, a pure-play power and electric grid services platform, from New Mountain Capital in a deal that underscores how private equity is racing to consolidate fragmented infrastructure services amid surging demand for grid modernization and renewable energy integration. Financial terms weren't disclosed, but the transaction positions Qualus as a buy-and-build vehicle in a sector where transmission and distribution bottlenecks have become the primary constraint on clean energy deployment.

The deal, announced February 3, marks Clearlake's latest infrastructure bet — and it's a telling one. While much of the capital markets focus has centered on renewable generation assets themselves, the real pinch point in the energy transition has shifted downstream to the unglamorous work of keeping electrons moving. Qualus provides engineering, construction, and maintenance services across transmission, distribution, substation, and renewable interconnection projects — the nuts-and-bolts work that determines whether new solar farms and wind installations can actually deliver power to customers.

New Mountain Capital, which backed Qualus's formation in 2021 through the combination of three regional grid services companies, is exiting after roughly four years. The firm's thesis — that fragmented regional players could be rolled up into a national platform with economies of scale — has been validated by the sector's trajectory. Federal infrastructure spending through the Bipartisan Infrastructure Law and Inflation Reduction Act has pumped billions into grid resilience projects, while utilities face mounting pressure to upgrade aging transmission networks and accommodate distributed energy resources.

"The power and electric grid services market is experiencing unprecedented demand driven by grid modernization, renewable energy integration, and the electrification of transportation and buildings," said Behdad Eghbali and José E. Feliciano, Clearlake co-founders and managing partners, in a statement. That's private equity speak for: the TAM just got a lot bigger, and we're buying the picks and shovels.

Qualus isn't a household name, and that's precisely the point. The company operates in the unglamorous but essential middle layer of the power sector: the contractors who design substations, string transmission lines, troubleshoot outages, and handle the physical integration work when a new solar or wind farm needs to tie into the grid. It's a services business, not an asset-heavy utility or generation play, which means it scales without the capital intensity of owning infrastructure.

The company serves investor-owned utilities, municipal power authorities, renewable developers, and industrial customers across the U.S. Its service lines span transmission and distribution construction, substation engineering and commissioning, underground and overhead power line installation, storm restoration, vegetation management, and renewable interconnection services. In other words: if it involves connecting power sources to power users, Qualus probably does it.

The business model here is labor and expertise arbitrage. Grid services work requires specialized skills — journeyman linemen, substation engineers, protection and control technicians — that are in chronically short supply. Companies like Qualus aggregate that talent and deploy it flexibly across geographies and project types, capturing margin on both the labor and project management. It's a high-touch, relationship-driven business where incumbent contractors have sticky customer relationships but limited ability to expand regionally without M&A.

Department of Energy estimates that U.S. transmission capacity needs to expand by 60% by 2030 to meet clean energy targets — a buildout that would require roughly $50 billion in annual capital spending, double the current run rate. Meanwhile, interconnection queues at regional grid operators are clogged with more than 2,000 gigawatts of proposed generation projects, the majority renewables, waiting for transmission upgrades that haven't been built yet.

New Mountain Capital formed Qualus in 2021 by combining three established grid services contractors: PAR Electrical Contractors (founded 1929, based in St. Paul), Harlan Electric (founded 1986, Oklahoma City), and Leidos Engineering (the infrastructure services arm of defense contractor Leidos). The combination created a platform with national reach, diversified end markets, and the scale to compete for larger utility and renewable developer contracts that regional shops couldn't handle alone.

The thesis was straightforward: take fragmented, family-owned or regional contractors, professionalize operations, add capital for equipment and hiring, cross-sell services, and capture margin improvement as the platform scales. It's a classic services roll-up, and in this case, the timing was impeccable — the firm's hold period coincided with the passage of the two largest federal infrastructure bills in a generation.

New Mountain, a growth-oriented private equity firm with $50 billion in AUM, typically targets businesses with recurring revenue, defensible market positions, and secular tailwinds. Qualus checked all three boxes. According to the firm's statements at the time of formation, the platform was designed to benefit from "long-term structural drivers including aging grid infrastructure, renewable energy adoption, and increasing electricity demand." Those drivers have only accelerated.

The platform's revenue and EBITDA figures haven't been disclosed, but industry comps suggest businesses of this scale and scope typically run at 8-12% EBITDA margins, with revenue in the $500 million to $1 billion range for a national multi-site platform. New Mountain's exit after four years implies the firm likely achieved its target returns — infrastructure services businesses in high-growth end markets have been commanding premium multiples in the 12-16x EBITDA range in recent transactions.

Four years is on the shorter end for a private equity exit, particularly in infrastructure services where value creation often takes 5-7 years. But the market for grid services platforms has heated up fast. Utilities are under regulatory pressure to harden grids against extreme weather, states are mandating renewable integration timelines, and the federal government is throwing money at transmission upgrades. All of that creates urgency for contractors who can deliver — and urgency creates valuation expansion.

Clearlake Capital, a Santa Monica-based firm with over $85 billion in AUM, is known for aggressive buy-and-build strategies in fragmented sectors. The firm's playbook: acquire a platform business with strong management and operational foundation, then layer on bolt-on acquisitions to expand capabilities, geographies, and customer relationships. Recent examples include its ownership of Pluralsight (tech training), Alteryx (data analytics), and Associations Inc. (healthcare credentialing) — all platforms that became serial acquirers under Clearlake's ownership.

In the infrastructure services space specifically, Clearlake has been active. The firm's portfolio includes Acuren (industrial inspection services), EagleView (property intelligence and analytics), and a stake in IEA Infrastructure & Energy Alternatives (heavy civil and renewable construction). Qualus fits the pattern: a services business with recurring customer relationships, exposure to long-cycle secular trends, and a fragmented competitive landscape ripe for consolidation.

"We see substantial opportunity to support Qualus's continued growth and market leadership through strategic initiatives and investments in people, technology, and infrastructure," Eghbali and Feliciano said in the announcement. Translation: expect M&A. The U.S. grid services market remains highly fragmented, with hundreds of small and midsize contractors serving regional utility territories. Qualus, as a Clearlake platform, will almost certainly pursue bolt-ons to expand its geographic footprint, add specialized capabilities (like high-voltage direct current transmission or grid-scale battery integration), and increase density within existing utility relationships.

Clearlake's operational value-add also extends beyond M&A. The firm employs a proprietary framework called O.P.S.® (Operations, People, Strategy) that focuses on process optimization, talent development, and strategic repositioning. For a labor-intensive business like Qualus, that could mean investments in workforce training programs, digital project management tools, safety systems, and fleet optimization — initiatives that improve margins and win rates on competitive bids.

International Energy Agency projects that global grid investment needs to double to $600 billion annually by 2030 to support electrification and decarbonization goals. In the U.S., the shift from centralized fossil fuel generation to distributed renewable resources fundamentally changes grid architecture — requiring bidirectional power flows, upgraded voltage regulation, and significantly more interconnection capacity. All of that work requires contractors like Qualus.

Qualus competes with a mix of large publicly traded contractors (Quanta Services, MYR Group, Pike Electric), regional specialists, and in-house utility crews. Quanta, the 800-pound gorilla of the space with $22 billion in annual revenue, operates at a scale Qualus can't match. But Quanta's size also makes it less nimble for mid-market projects, and its focus has increasingly shifted toward large transmission mega-projects and international markets. That leaves room for regional and super-regional platforms like Qualus to serve second-tier utilities, municipal authorities, and renewable developers who need responsiveness and local relationships.

MYR Group, another public comp, posted $3.2 billion in revenue in 2023 and trades at roughly 14x forward EBITDA — a useful valuation benchmark for where Qualus might be valued in a secondary or IPO scenario down the line. The private equity-backed tier of the market — where Qualus now sits — includes platforms like Rosendin Electric (backed by Ares), Cupertino Electric (Goldman Sachs Asset Management), and Miller Electric (Court Square Capital Partners). These platforms are all pursuing similar strategies: buy regionals, integrate operations, and ride secular growth in grid capex.

The business case for owning a grid services contractor hinges on sustained demand visibility. Right now, that visibility is exceptionally strong. Federal programs like the Grid Resilience and Innovation Partnerships (GRIP) program and the Preventing Outages and Enhancing the Resilience of the Electric Grid (POWER) grant program are directing $13 billion toward transmission and distribution upgrades. State-level mandates — California's SB 100 (100% clean electricity by 2045), New York's Climate Leadership and Community Protection Act, and similar laws in Illinois, Massachusetts, and Washington — are forcing utilities to build out interconnection capacity for renewables at an accelerating pace.

Utilities themselves are spending more on grid capex as a share of total investment. According to EEI, investor-owned utilities are expected to invest $179 billion in transmission and distribution infrastructure in 2024-2025, up from $151 billion in 2020-2021. That's a 19% increase in just four years. Much of that spending is driven by interconnection backlogs: as of mid-2024, there were roughly 12,000 projects totaling 1,350 GW in interconnection queues nationwide, with average wait times stretching to five years.

The economics of interconnection work are particularly attractive for contractors. Renewable developers are willing to pay premium rates for experienced crews who can navigate the complex approval and construction process, because every month of delay costs them revenue. Utilities, meanwhile, are under regulatory obligation to process interconnection requests and upgrade infrastructure to accommodate new generation — which means the work is largely non-discretionary.

Qualus's sweet spot — transmission, distribution, substations, and renewable interconnection — is precisely where the bottlenecks are most acute. The company isn't building generation assets or speculating on power markets. It's doing the decidedly unglamorous work of pouring concrete for substation foundations, pulling wire, calibrating protection relays, and managing outage schedules. But that work is the constraint right now, which gives platforms like Qualus pricing power and customer stickiness.

Bureau of Labor Statistics projects 6% annual growth in electrical power-line installer and repairer jobs through 2032, faster than the national average for all occupations.

Platforms like Qualus that invest in apprenticeship programs, safety training, and retention initiatives have a structural advantage over smaller contractors who can't offer career paths or benefits. Clearlake's capital and operational resources could allow Qualus to scale workforce development programs — a long-term competitive moat in a sector where talent is the scarcest asset.

Neither Clearlake nor New Mountain disclosed the purchase price, equity check size, or debt structure of the transaction. That's typical for mid-market private equity deals where buyers prefer to keep valuation metrics out of the public domain to avoid setting comps for future acquisitions. However, recent grid services transactions provide useful context. When Goldman Sachs Asset Management acquired a majority stake in Cupertino Electric in 2022, industry sources pegged the valuation at roughly 13x EBITDA. Pike Electric, which was taken private by CD&R in 2021, was valued at approximately $2 billion on an enterprise basis.

If Qualus is generating, say, $75-100 million in EBITDA — a reasonable estimate for a platform of this scale — a 12-14x multiple would imply an enterprise value in the $900 million to $1.4 billion range. Clearlake typically uses leverage ratios of 4-5x EBITDA in infrastructure services deals, which would suggest roughly $400-500 million in equity and $500-700 million in debt. These are back-of-the-envelope figures, but they're consistent with how Clearlake structures platform acquisitions in similar sectors.

The deal is subject to customary regulatory approvals and is expected to close in Q2 2025. Qualus will continue to operate under its existing brand and leadership team, with CEO David Dunlap remaining in place — a signal that Clearlake views the current management as capable executors of the buy-and-build strategy. Raymond James and Weil, Gotshal & Manges served as financial and legal advisors to Clearlake. Jefferies and Kirkland & Ellis advised New Mountain.

The involvement of bulge-bracket advisors on both sides suggests this was a competitive process, likely with multiple bidders. Infrastructure services platforms with strong growth profiles and exposure to secular tailwinds are highly sought after in the current environment — particularly by firms like Clearlake that have dry powder and a proven track record in buy-and-build strategies.

For New Mountain, the exit likely represents a strong return. The firm's infrastructure and energy vertical has been active in recent years, with exits from businesses like Granite US Holdings (fuel and propane distribution) and investments in asset-light infrastructure services. The Qualus exit fits the pattern: back a sector experiencing structural growth, professionalize operations, achieve scale, and sell to a buyer with a longer holding horizon and M&A firepower.

Under Clearlake's ownership, Qualus will almost certainly expand through acquisition. The firm's stated strategy is to "support Qualus's continued growth and market leadership," which in private equity vernacular means aggressive M&A. The target list likely includes regional contractors with strong utility relationships in underserved geographies (the Southeast, Texas, and parts of the Midwest where renewable interconnection demand is spiking), as well as specialized capabilities like HVDC transmission, grid-scale battery integration, or microgrid design and construction.

Organic growth will also be a focus. With federal and state dollars flowing into grid modernization programs, Qualus will compete for larger contracts and longer-term master service agreements with utilities and renewable developers. The company's ability to operate nationally — rather than being confined to a single region or utility territory — gives it an advantage in bidding for multi-site projects, like a solar developer building out a portfolio across five states or a utility upgrading substations system-wide.

Technology investments are another likely area of focus. Modern grid construction increasingly involves digital tools — 3D modeling for substation design, drone-based line inspection, real-time project management dashboards, and predictive maintenance analytics. Platforms that can offer turnkey digital solutions alongside physical construction services win higher-margin contracts and build stickier customer relationships. Clearlake has a history of investing in technology enablement across its portfolio, and Qualus is a natural candidate for that playbook.

The exit horizon for Clearlake is likely 5-7 years, putting a potential sale or IPO in the 2029-2031 timeframe. By then, the grid modernization cycle will be in full swing, interconnection backlogs will have (theoretically) cleared, and the market for infrastructure services businesses will have further matured. If Clearlake executes its playbook — doubling or tripling EBITDA through a combination of organic growth, margin improvement, and M&A — the firm could be looking at a $3-5 billion exit valuation.

That's the bet, anyway. But it hinges on a few things going right: sustained federal and state spending on grid infrastructure, continued renewable energy adoption, successful integration of acquired businesses, and avoiding the operational pitfalls that plague services roll-ups (customer concentration, labor cost inflation, safety incidents, integration missteps). Clearlake's track record suggests they know how to manage those risks. Whether Qualus becomes a $5 billion platform or stalls out at $2 billion will depend on execution — and on whether the grid modernization story stays hot long enough to justify the entry multiple.

The Qualus transaction is part of a broader trend: private equity's systematic colonization of infrastructure services. These businesses — utilities contractors, industrial maintenance providers, telecom installers, environmental remediation firms — used to be family-owned or regional players with stable but unspectacular growth. Then someone realized that infrastructure spending was about to go exponential, these businesses had recurring revenue and sticky customers, and the market was absurdly fragmented.

The result has been a wave of platform formation and consolidation. In electrical construction alone, PE-backed deals have totaled more than $15 billion in aggregate transaction value since 2020, according to PitchBook data. KKR, Goldman Sachs Asset Management, Ares, Court Square, AEA Investors, and now Clearlake have all built positions in the space. The playbook is nearly identical across deals: acquire a regional leader, bolt on 3-8 smaller competitors, professionalize operations, and either sell to a larger PE firm or take the company public.

What makes grid services particularly attractive is the convergence of tailwinds. You have federal infrastructure spending (bipartisan political support, already appropriated), state clean energy mandates (regulatory obligation, not discretionary), utility capex cycles (multi-year visibility, rate-base recovery), and private sector renewable investment (corporate PPAs, tax equity structures). Each of those drivers independently would support steady growth. Together, they create a demand surge that's rare in infrastructure services.

The risk, of course, is that everyone sees the same opportunity — which drives up acquisition multiples, compresses returns, and makes bolt-on M&A increasingly expensive. If Clearlake overpays for add-ons or if grid capex spending plateaus sooner than expected, the math gets harder. But for now, the sector remains undersupplied relative to demand. And as long as that dynamic holds, platforms like Qualus — with scale, national reach, and access to capital — will keep winning work and winning bids.
