Affiliated Managers Group (AMG), an investment management firm, announced that it has entered into a definitive agreement to acquire a minority equity stake in Qualitas Energy, an investment firm focused on renewable energy, the energy transition, and sustainable infrastructure.
Under the terms of the deal, the Qualitas Energy management team will retain majority ownership and continue to lead the company’s day-to-day operations, including all investment, strategic, and operational decisions.
As part of the transaction, Qualitas Energy’s Executive Chairman, Iñigo Olaguíbel, and CEO, Oscar Pérez, along with other members of the senior management team, will enter into additional long-term commitments with the firm.
“Given the increasing focus on energy independence and security in Europe, along with the firm’s distinctive approach, vertically integrated industrial platform, and locally based teams with deep knowledge of their respective geographies, Qualitas Energy is well-positioned to build on its business momentum. I am delighted to welcome Iñigo, Oscar, and their partners to our Affiliate group,” said Jay C. Horgen, President and Chief Executive Officer of AMG.
The terms of the transaction remained undisclosed. The transaction is expected to close in the fourth quarter of 2025, subject to customary closing conditions.

This capital is stated to have been deployed across a diverse range of clean energy sectors, including solar, wind, battery storage, hydroelectric power, and renewable natural gas.
