Kohlberg backs Loenbro in major deal to expand critical services.

Kohlberg has agreed to acquire a majority stake in Loenbro, the Westminster, Colorado firm that provides electrical, mechanical and structural services to data centres and other mission‑critical infrastructure. The transaction, whose financial terms were not disclosed, will keep Braemont Capital and Loenbro’s management team as meaningful equity holders as the business scales nationally.

Founded in 2000, Loenbro has spent more than two decades building a single‑source offering across maintenance, new build and retrofit projects in the Mountain West. The company’s service mix—electrical, fabrication, mechanical, structural, inspection and soft‑craft—targets the growing market for resilient infrastructure that supports hyperscalers, colocation providers and essential commercial customers.

The buyer, Kohlberg, a US middle‑market private equity firm that manages roughly $17 billion of investor capital, said it will back Loenbro’s next expansion phase. Kohlberg partners Benjamin Mao and Ben Yu were quoted outlining plans to bolster operational capabilities and pursue new growth avenues across data‑centre and critical services, while continuing to emphasise safety and quality.

Loenbro’s chief executive, Daniel Cowan, framed the deal as a strategic step to convert regional strength into a national platform. Under the partnership, management will continue to lead day‑to‑day operations with Braemont’s Jeff Volling confirming his firm will stay invested and support the company’s scaling strategy.

Industry context points to sustained demand for third‑party specialist contractors as data‑centre construction and lifecycle spend remain robust. Support services—ongoing maintenance, retrofits and commissioning—are frequently cited as higher‑margin, recurring revenue streams for contractors able to deliver consistently in highly regulated, uptime‑sensitive environments.

From a transaction perspective, advisors lined up on both sides. Evercore and Kirkland & Ellis advised Loenbro, while a team including Harris Williams, KeyBanc Capital Markets and Stifel supported Kohlberg. Greenberg Traurig and Kirkland & Ellis acted as legal counsel to the buyer. The deal remains subject to customary closing conditions and regulatory approvals.
