Clearlake Capital Group has agreed to acquire Qualus Corporation from New Mountain Capital, marking a significant transaction in the power and electric grid services sector as demand for modernization and resiliency continues to accelerate across the United States. The financial terms of the deal were not disclosed.
Qualus operates as a specialized power solutions provider supporting the transformation of grid infrastructure. The company delivers advisory, engineering, digital, and field services designed to enhance grid resiliency, security, and sustainability. Its client base includes major investor-owned utilities as well as commercial and industrial organizations navigating increasing electrification demands.
The acquisition comes at a time when the U.S. power sector is under pressure from aging infrastructure, rising electricity consumption, and the integration of renewable energy and data center-driven load growth. Clearlake is expected to provide strategic and operational support to help scale Qualus’ capabilities and expand its role in addressing these challenges.
New Mountain Capital, which has owned Qualus for the past five years, highlighted the company’s growth during its investment period and expressed confidence in its continued trajectory under new ownership.
Advisors on the transaction included AEC Advisors as lead financial advisor, Harris Williams as co-financial advisor, and Simpson Thacher & Bartlett along with Wachtell, Lipton, Rosen & Katz as legal counsel. Financing for the deal was arranged with participation from Apollo, Goldman Sachs Alternatives, and Clearlake.
