Stamford, Conn. - April 16, 2025 - Altus Power, Inc. (“Altus Power” or the “Company”) (NYSE: AMPS), a leading commercial-scale provider of clean, electric power, today announced the completion of its acquisition by TPG through its TPG Rise Climate Transition Infrastructure strategy in an all-cash transaction that valued the Company at approximately $2.2 billion, including outstanding debt.

“The successful close of this transaction marks a pivotal moment for Altus Power, our stockholders, employees and partners. By partnering with TPG Rise Climate Transition Infrastructure, who shares our long-term vision for the future of clean energy, we believe we are unlocking significant value for our stockholders and accelerating our long-term growth strategy,” said Gregg Felton, CEO of Altus Power. “As demand for power continues to rise, businesses, utilities and communities are desperate for scalable, grid-enhancing solutions that generate incremental power in locations where it’s needed. We expect this partnership to strengthen our ability to deliver clean energy faster and at greater scale, positioning Altus to lead the next phase of clean energy expansion.”
