Eos Energy Enterprises, Inc. entered into an Amended and Restated Limited Liability Company Agreement with CCM Frontier JV Holdco, LLC and HBC MSF Capital Solutions Blocker II LLC to govern Frontier Power USA Parent, LLC, a joint venture focused on the company’s frontier power platform.
Eos contributed $112,637,878.86 for 112,637,879 Class B Units, while CCM Frontier contributed $100 million for 100,000,000 Class A-2 Units and received 50,000,001 Class A-1 founder units, and HBC contributed $50 million for 50,000,000 Class C Units. Governance is via a seven-member board with four managers appointed by CCM Frontier and up to three by Eos, with specified consent rights and distribution waterfalls targeting a 10% pre-tax IRR on invested capital.
The company also issued 20,017,772 CCM Warrants and 10,008,886 HBC Warrants, each exercisable for one share of common stock at $5.481 for ten years, granted HBC exchange rights for up to 50,000,000 Class C Units into up to 9,122,422 shares of common stock subject to a 9.8% ownership cap, agreed to related registration rights, and obtained a third amendment to its U.S. Department of Energy loan guarantee to permit the JV structure and related commercial arrangements, including the Thorn Hill site.
Eos Energy Enterprises reported strong top-line growth but continued heavy losses for the quarter ended June 30, 2026. Revenue was $68.8 million, up 351% year over year, with about $55.0 million from a Cerberus‑financed project later contributed to the Frontier Power USA joint venture. Backlog reached a record $807 million, representing 3.4 GWh, and the commercial opportunity pipeline totaled $24.6 billion.
Profitability remains challenging. The company posted a $48.8 million gross loss and gross margin of -71%, a $275.7 million net loss mainly from fair value adjustments, and an adjusted EBITDA loss of $71.4 million. Total cash, including restricted cash, was $364.1 million at June 30, 2026. Eos tightened its 2026 revenue outlook to $300 million–$350 million, from $300 million–$400 million, as it evaluates consolidating manufacturing into its Thorn Hill facility, where a new production line is delivering faster cycle times and is expected to improve efficiency and margins over time.
Eos Energy Enterprises detailed preliminary results of a rights offering to purchase up to 27,367,171 Units at $5.481 per Unit, each consisting of one share of common stock and 0.4388 of a warrant with a $5.481 exercise price per whole share.
As of the July 21, 2026 Expiration Date, subscriptions totaled 6,885,218 Units, and the company expects aggregate gross proceeds of $37.7 million. Including this capital, a previously announced investment from Hudson Bay Capital Management and a commitment from Cerberus Capital Management, approximately $263 million in gross proceeds have been raised in support of Frontier Power USA, which is expected to initially support more than $1 billion of deployable project capital. The common stock and warrants comprising the Units will separate and be issued individually, with distribution expected on or about August 3, 2026, and the company has applied to list the warrants on Nasdaq under the symbol “EOSEW,” with completion of the rights offering remaining subject to specified conditions.
Eos Energy Enterprises reported preliminary second-quarter 2026 results. It expects revenue of $68 million to $69 million, the highest quarterly revenue in its history, driven by more than a three-fold increase in shipments versus the prior-year period. Revenue recognized in the first half of 2026 has already surpassed total revenue for 2025.
As of June 30, 2026, Eos anticipates a record backlog of approximately $807 million, about 25% higher than the prior quarter, with new orders exceeding shipments. The company projects a gross margin loss between 69% and 73%, reflecting start-up costs and lower initial volumes during its manufacturing ramp, including the launch of Battery Line 2 and progress toward a targeted 4 GWh annual run-rate capacity by year-end.
Total cash, including restricted cash, is expected to be approximately $364 million, with about $78 million of customer collections in the quarter, exceeding revenue. These figures are preliminary, unaudited management estimates and may differ materially from final results. Full second-quarter results are scheduled for August 5, 2026, followed by an earnings call and shareholder Q&A.
