EDISON, N.J., Nov. 18, 2025 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ:EOSE) ("Eos" or the "Company") today announced its intention to offer, subject to market and other conditions, $500,000,000 aggregate principal amount of convertible senior notes due 2031 (the "notes") in a private offering (the "Offering") to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). Eos also expects to grant the initial purchasers of the notes an option to purchase, for settlement within a period of 13 days from, and including, the date the notes are first issued, up to an additional $75,000,000 aggregate principal amount of notes.

The notes will be senior, unsecured obligations of Eos, will accrue interest payable semi-annually in arrears and will mature on December 1, 2031, unless earlier repurchased, redeemed or converted. Noteholders will have the right to convert their notes in certain circumstances and during specified periods. Eos will settle conversions by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at Eos's election. However, unless and until Eos increases the number of authorized shares of its common stock, or otherwise increases the number of shares of its common stock available to settle conversions of the notes, and, in each case, reserves the required number of shares solely for issuance upon conversion of the notes, Eos will settle all conversions entirely in cash.

The notes will be redeemable, in whole or in part (subject to certain limitations), for cash at Eos's option at any time, and from time to time, on or after December 5, 2028 and on or before the 41st scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of Eos's common stock exceeds 130% of the conversion price for a specified period of time and certain other conditions are satisfied. The redemption price will be equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

If certain corporate events that constitute a "fundamental change" occur, then, subject to a limited exception, noteholders may require Eos to repurchase their notes for cash. The repurchase price will be equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

The interest rate, initial conversion rate and other terms of the notes will be determined at the pricing of the Offering.

Eos also announced today its intention to offer shares of its common stock in a registered direct offering, subject to market and other conditions, to a limited number of purchasers (the "Concurrent Equity Offering").

Eos expects to use the net proceeds from the Offering, together with the net proceeds from the Concurrent Equity Offering, if it is consummated, (i) to repurchase a portion of Eos's outstanding 6.75% convertible senior notes due 2030 (the "Existing 2030 Convertible Notes") as described below; and (ii) for general corporate purposes.

Concurrently with the pricing of the Offering, Eos expects to enter into one or more separate, privately negotiated transactions with a limited number of holders of the Existing 2030 Convertible Notes to repurchase a portion of the Existing 2030 Convertible Notes for cash (the "Repurchases"), in each case, subject to market and other conditions. The terms of each Repurchase will depend on a variety of factors, including the market price of Eos's common stock and the trading price of the Existing 2030 Convertible Notes at the time of such Repurchase, and the Repurchase will be subject to closing conditions that may not be satisfied. No assurance can be given as to how many, if any, of the Existing 2030 Convertible Notes will be repurchased or the terms on which they will be repurchased. In addition, following the completion of the Offering, Eos may repurchase additional Existing 2030 Convertible Notes.

In connection with any repurchase of the Existing 2030 Convertible Notes, certain holders of the Existing 2030 Convertible Notes that participate in any of these repurchases may purchase or sell shares of Eos's common stock in the open market or enter into or unwind various derivative transactions with respect to Eos's common stock to unwind any hedge positions they may have with respect to the Existing 2030 Convertible Notes or to hedge or unwind their exposure in connection with these transactions. The amount of Eos's common stock to be sold or purchased by such holders or the notional number of shares of Eos's common stock underlying such derivative transactions may be substantial in relation to the historic average daily trading volume of Eos's common stock. These activities may adversely affect the trading price of Eos's common stock and the trading price of the notes. Eos cannot predict the magnitude of such market activities or the overall effect they will have on the price of the notes or Eos's common stock.

The completion of the Concurrent Equity Offering is conditioned upon the completion of the Offering. The completion of the Offering is not contingent on the completion of the Concurrent Equity Offering.

The offer and sale of the notes and any shares of common stock issuable upon conversion of the notes have not been, and will not be, registered under the Securities Act or any other securities laws, and the notes and any such shares cannot be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any other applicable securities laws. This press release shall not constitute an offer to sell, or a solicitation of an offer to buy any securities, nor shall there be any sale of any securities, in any state or other jurisdiction in which such an offer, solicitation or sale would be unlawful. This press release also shall not constitute an offer to purchase or a solicitation of an offer to sell the Existing 2030 Convertible Notes.
