EDISON, N.J. and NEW YORK, May 13, 2026 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ:EOSE), America's leading innovator in designing, manufacturing, and providing zinc-based long duration energy storage (LDES) systems sourced and manufactured in the United States, and Cerberus Capital Management, L.P. ("Cerberus"), one of the country's largest alternative investment firms, today 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.
Manufacturers in capital-intensive industries, from aviation to power generation, have long used financing vehicles to accelerate customer deployment, and those platforms have generated significant value for stakeholders over time. Frontier USA is targeting to be the first application of that proven playbook to long-duration energy storage.
Accelerated Project Deployment
Eos and Frontier Power USA entered into a firm 2 GWh capacity reservation agreement, expanding Eos' March 31, 2026 backlog. Frontier Power USA is expected to deploy this capacity across commercial and industrial applications, AI data centers, and utility-scale projects, drawing from a multi GWh project pipeline which is under active development.
Firm Technology Performance Insurance (TPI) with Ariel Green
Simplifying project bankability and accelerating asset deployment, Frontier Power USA has secured a firm Technology Performance Insurance (TPI) framework with Ariel Green, a division of Ariel Re and a leader in clean energy insurance. The framework contemplates a 15-year non-cancellable coverage, which will be sized at the project level with a multi-year total policy capacity of up to approximately $1.5 billion, written through highly rated insurance markets including syndicates at a Lloyd's of London consortium (A+/AA-).
This framework is designed to meet the risk and underwriting standards of institutional lenders. By providing consistent, long-term performance protection, the structure enables projects to be financed on investment-grade terms, supporting longer tenors and a lower cost of capital. Alongside this policy, Frontier Power USA is evaluating two complementary debt financing paths under the TPI framework: investment-grade-rated debt placed with institutional investors and captive insurance platforms, and project-level facilities with traditional commercial bank lenders.
Anchored by Institutional Capital & Extensive Operating Experience
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.
Rights Offering
To fund its equity contribution in Frontier Power USA, Eos intends to launch a rights offering targeting approximately $150 million. In the rights offering, existing Eos common shareholders, including retail investors, would receive a distribution of subscription rights to purchase Eos securities along with receiving expected warrants. These rights would be distributed based on how much Eos common stock an existing shareholder owns as of the record date for the distribution, providing the opportunity to maintain proportional economic interest in Eos' participation in Frontier. The structure is designed to broaden access, preserve flexibility for non-participating holders through transferability, and limit incremental dilution for those who exercise. The terms of any distribution of rights have not yet been determined, and the distribution is subject to conditions including board declaration of a distribution, shareholder approval of the increase in our authorized shares and certain other consents under our existing debt agreements.
Strategic Rationale
Frontier Power USA is expected to be a first-of-its kind: A vertically integrated BESS developer and planned IPP with direct OEM access from cell to software. The company will have direct access to an OEM at the cell IP level, through module and system architecture to the proprietary software layer, creating end-to-end integration that reduces the risks in third party assembled supply chains. It's a purpose-built independent developer and IPP working in direct partnership with Eos and an expected embedded fully-funded financing vehicle.
It is expected to be a self-reinforcing growth engine. Cash flow generated by operating projects will be systematically reinvested into the platform, funding new project origination, accelerating Eos equipment deployment, and compounding the value of the integrated technology stack.
Together, the platform is intended to:
- Establish a scalable capital platform for gigawatt-scale Eos Z3 deployment in markets where long-duration storage is uniquely positioned to address grid resiliency and load growth
- Optimize project economics through dedicated financing, expanded institutional capital access, and direct relationships with offtakes and infrastructure partners
- Enable Eos shareholders to participate alongside strategic and institutional partners in long-term project-level value creation
Management Commentary
"We believe that Frontier Power USA will bring the speed and ability to scale that the grid urgently needs, at a time when the opportunity set is being driven by energy security requirements and sustained growth in power demand from electrification and AI. By pairing the company's execution and deployment platform with Eos' differentiated long-duration storage technology and expanding U.S. manufacturing base, we believe this model creates a credible path to delivering storage capacity at scale. The platform is designed to translate proven technology into reliable, deployable assets that can keep pace with the system's evolving needs."
— Aaron Maczonis, Managing Director at Cerberus Capital Management.
"As energy storage projects scale, bridging the gap between technology innovation and associated liabilities becomes essential. This transaction through Frontier Power USA shows how TPI can play that role, supporting both bankability and repeatable platform growth across the U.S."
— Jamie Daggett, Energy Storage Practice Lead, Ariel Green
"Frontier Power USA changes the speed of long-duration storage financing and deployment, allowing customers to have faster access to capital and deep expertise in project development. We feel confident that this will give Eos a new growth trajectory as we continue to expand manufacturing capacity. The platform pairs our integrated technology stack with institutional capital and a lender-ready performance framework that is designed to deliver what matters most: electrons to the grid."
Mastrangelo concluded, "We believe the planned structure maintains shareholder alignment by allowing Eos investors to participate pro rata in Frontier's Power USA's growth via Eos ownership while ensuring project capital is governed independently and on arm's-length commercial terms."
— Joe Mastrangelo, Chief Executive Officer Eos Energy
