Private equity firm Siris has agreed to acquire a majority stake in renewable energy services provider TAKKION from funds managed by Apollo.
The transaction is expected to close in the second quarter of 2026 subject to customary closing conditions, the companies said.
They added that TAKKION generated approximately $600m in revenue in 2025 and provides services across renewable energy operations, maintenance and repair, construction, transportation and fixed site logistics.
Founded in 2019, the company operates a diversified energy services platform supporting developers, utilities and OEMs.
Headquartered in Centennial, Colorado, TAKKION employs around 2,000 people and delivers services across the renewable energy sector.
Siris said it plans to work with the company’s management team to optimise operations and expand service capabilities into adjacent sectors including solar, battery storage and transmission.
“TAKKION provides a mission-critical service, supporting the renewable energy sector, and is well positioned to further capitalize on the accelerating energy demands driven by AI data center expansion,” said Frank Baker, co-founder and managing partner of Siris.
“With a strong team, a culture of safety and operational excellence, and deep customer trust, we are well positioned for this next chapter of growth,” said Pete Bierden, chief executive of TAKKION.
