Eos Energy Enterprises, Inc. announced the record date for a rights offering to fund its capital contribution in the Frontier Power USA joint venture. The record date for the Rights Distribution will be at 5:00 pm New York time on July 1, 2026, and the distribution date will be on July 2, 2026. Eligible holders include holders of the company's common stock and warrants issued on specific dates in 2023 and 2025.

The company expects to distribute rights to acquire units comprised of common stock and warrants. Each right will entitle an Eligible Holder to purchase units at a subscription price equal to an approximate 10% to 20% discount to the volume weighted average trading price of the company's common stock for a 15 to 30 day trading period ending on and including the trading day prior to the Record Date. The warrants included in the Units will have a value equal to approximately 25% to 50% of the aggregate rights offering amount, based on a Black-Scholes methodology.

The rights offering will include an over-subscription privilege to permit Eligible Holders who exercise their basic subscription rights in full to purchase additional unsubscribed Units, subject to certain restrictions. Further details on the terms and procedures will be announced at the commencement of the rights offering.

Pursuant to the terms of certain outstanding warrants and convertible notes, the company is required to provide advance notice of the Rights Distribution, including a 20-calendar-day notice period for certain warrant holders and a 10-scheduled trading-day notice period for convertible note holders.

The rights offering will be made pursuant to the company's existing effective shelf registration statement on Form S-3 filed with the Securities and Exchange Commission (SEC) and a prospectus supplement to be filed prior to the commencement of the offering. The completion of the rights offering remains subject to certain conditions, and the company reserves the right to amend or terminate the offering at any time prior to its expiration date.
