Eos Energy Enterprises, Inc. Prices Upsized $225,000,000 Convertible Senior Notes Offering

EDISON, N.J., May 30, 2025 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ:EOSE) ("Eos" or the "Company") today announced the pricing of its offering of $225,000,000 aggregate principal amount of 6.75% convertible senior notes due 2030 (the "notes") in a private 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"). The offering size was increased from the previously announced offering size of $175,000,000 aggregate principal amount of notes. The issuance and sale of the notes are scheduled to settle on June 3, 2025, subject to customary closing conditions. Eos also granted 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 $25,000,000 aggregate principal amount of notes.

The notes will be senior, unsecured obligations of Eos and will accrue interest at a rate of 6.75% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2025. The notes will mature on June 15, 2030, unless earlier repurchased, redeemed or converted. Before March 15, 2030, noteholders will have the right to convert their notes only upon the occurrence of certain events. From and after March 15, 2030, noteholders may convert their notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. 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. The initial conversion rate is 196.0784 shares of common stock per $1,000 principal amount of notes, which represents an initial conversion price of approximately $5.10 per share of common stock. The initial conversion price represents a premium of approximately 27.5% over the public offering price in the concurrent common stock offering described below. The conversion rate and conversion price will be subject to adjustment upon the occurrence of certain events.

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 June 20, 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 a "fundamental change" (as defined in the indenture for the notes) occurs, then, subject to a limited exception, noteholders may require Eos to repurchase their notes for cash. The repurchase price will be equal to (x) 110% (or, if the effective date of such fundamental change is on or after June 15, 2027, 105%) of the principal amount of the notes to be repurchased, plus (y) accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

Eos estimates that the net proceeds from the offering of notes will be $216,000,000 (or $240,000,000 if the initial purchasers fully exercise their option to purchase additional notes), after deducting the initial purchasers' discounts and commissions. Eos intends to use the net proceeds from this offering, together with the net proceeds from the underwritten public offering of common stock referred to below, if it is consummated, (i) to repurchase the full $126 million aggregate principal amount outstanding of its 5%/6% Convertible Senior PIK Toggle Note due 2026 in a privately negotiated transaction for approximately $131 million; (ii) to prepay $50 million of outstanding borrowings due under its credit agreement, dated June 21, 2024, by and between Eos and CCM Denali Debt Holdings, LP (the "Credit Agreement"); and (iii) for general corporate purposes. Upon the prepayment of $50 million of outstanding borrowings under the Credit Agreement, the PIK interest rate under the Credit Agreement will decrease from 15% to 7% and the financial covenants thereunder will be waived until 2027. CCM Denali Equity Holdings, LP has agreed that upon the consummation of the offering it will not transfer any securities issued to it under the Securities Purchase Agreement, dated June 21, 2024, between the Company and CCM Denali Equity Holdings, LP prior to June 21, 2026.

In a separate press release, Eos also announced today the pricing of its previously announced underwritten public offering of 18,750,000 shares of its common stock, plus up to an additional 2,812,500 shares of its common stock that the underwriters of the common stock offering have the option to purchase from Eos, at a public offering price of $4.00 per share. The issuance and sale of the common stock are scheduled to settle on June 2, 2025, subject to customary closing conditions. The completion of the offering of the notes is not contingent on the completion of the offering of common stock, and the completion of the offering of common stock is not contingent on the completion of the offering of the notes. This press release does not constitute an offer to sell, or the solicitation of an offer to buy, any common stock in the public offering.
