NEW YORK and NEWPORT BEACH, Calif., May 21, 2026 (GLOBE NEWSWIRE) -- Frontier Power USA ("FPUSA"), a long duration energy storage development and investment company, with its affiliates, today announced the signing of a transaction to acquire a 480 MWh portfolio of battery energy storage system ("BESS") development projects from Bimergen Energy Corporation (NYSE: BESS) ("Bimergen").

Eos Energy Enterprises offers a high-growth story in long-duration energy storage, with a massive $24 billion pipeline and strong structural demand. EOSE's recent financials disappointed, missing Q4 estimates and maintaining lower 2026 revenue guidance with Q1 results, but backlog and partnerships support future growth. Execution risk is elevated: EOSE faces mounting losses, negative gross margins, and must ramp production at Thorn Hill to achieve profitability.

Eos Energy Enterprises, Inc. remains a compelling Sell due to persistent dilution, questionable capital allocation, and circular joint venture structures. The Cerberus partnership, including a 2 GWh joint venture and $150M rights offering, primarily benefits Cerberus and exacerbates shareholder dilution. EOSE's financials reveal ongoing losses, a $506M debt load, and accounting-driven net income disconnected from core business performance.

Eos Energy Enterprises has demonstrated strong manufacturing progress, with Q1 2026 revenue quadrupling and gross margin trajectory improving significantly year-over-year. I maintain a hold rating, as valuation remains unjustified until positive adjusted gross margin is confirmed with Line 2 production in H2 2026. EOSE's capital cost story is transforming, with debt restructured from 26.5% to 7% and a path toward investment-grade project finance via Frontier Power USA.
