Eos Energy Enterprises, Inc. and Cerberus Capital Management, L.P. announced the intention to capitalize Frontier Power USA, an independent development and investment company established to build, own, and operate a diversified portfolio of long-duration battery energy storage projects deploying Eos? proprietary zinc bromide based Z3 technology with the strategy of becoming an Independent Power Producer (IPP). Frontier Power USA is expected to unify three core capabilities that have historically sat across multiple stakeholders: Eos?

vertically integrated technology stack, Cerberus?s institutional capital and operating experience, and a performance wrap to be provided by Ariel Green, which underwrites Z3 performance. The performance wrap underpins the structure and will allow project debt to achieve investment-grade characteristics at competitive terms. This combination is designed to compress the project lifecycle from commitment to first energy cycle and convert Eos? opportunity pipeline or projects with secured interconnection and offtake into funded, under construction assets.

Frontier USA is targeting to be the first application of that proven playbook to long-duration energy storage. Cerberus Capital Management is anchoring Frontier Power USA with a $100 million equity commitment and is concurrently extending its existing Eos lock-up through year end 2026; Cerberus is expected to receive Eos warrants, as well as controlling equity in Frontier Power USA in exchange for its commitment. The funding of Cerberus?s equity commitment is subject to certain closing conditions.

As a standalone entity, Frontier Power USA will separate project-level capital from the Eos corporate balance sheet, allowing Eos to focus on technology development, manufacturing, and project execution. Frontier Power USA is expected to be led by a CEO with a deep operating track record in energy storage development and project finance, supported by a dedicated origination and structuring team.
