For Shareholders

For Shareholders

A new chapter in how Eos serves its market.

On May 13, Eos and Cerberus announced Frontier Power USA. It will be an industry-first application of a financing vehicle in the long-duration energy storage market. And it is a continuation of how Eos has always operated: breaking through the limits of conventional thinking.

As of July 23, 2026, Eos announced that the capital necessary to fund its investment in Frontier Power USA had been secured through its rights offering, an announced investment from Hudson Bay Capital Management, and the commitment from Cerberus Capital Management, resulting in expected gross proceeds raised above the ~$250 million aggregate equity target established with the joint venture, which was announced in May.

With interconnection secured and offtake agreements locked, customers are ready to deploy projects, and Frontier Power USA will enable faster execution by shortening the project lifecycle from commitment to first energy cycle. As an independent entity, Frontier Power USA separates project-level capital from the Eos corporate balance sheet.
