Eos Energy Enterprises, Inc. has filed a preliminary prospectus supplement for a registered direct offering of common stock together with detachable warrants.

Eos Energy Enterprises, Inc. is conducting a registered direct offering of 35,855,647 shares of common stock at $12.78 per share, for expected gross proceeds of about $458.2 million before expenses. At completion, the company expects to have 317,544,042 shares outstanding. Concurrently, it is privately offering 1.75% convertible senior notes due 2031 with $525 million principal amount (plus a $75 million option) to qualified institutional buyers.
Eos plans to use the stock and note proceeds together to repurchase $200 million principal of its 6.75% Convertible Senior Notes due 2030 for approximately $564.6 million, with the remainder for general corporate purposes. The company highlights significant historical losses, negative cash flows and reliance on external capital, noting substantial doubt about its ability to continue as a going concern without successful execution of its growth and financing plans. The offering will significantly dilute existing shareholders and adds a large new layer of convertible debt while extending its debt maturity profile.
Eos Energy Enterprises, Inc. is launching a registered direct offering of common stock on Nasdaq under the symbol EOSE. The shares will be sold at a price per share equal to the closing market price on the date of the prospectus supplement, with Goldman Sachs & Co. LLC acting as exclusive placement agent on a reasonable best-efforts basis.
At the same time, Eos is privately offering $500,000,000 aggregate principal amount of convertible senior notes due 2031, with an option for initial purchasers to buy up to an additional $75,000,000. Eos plans to use the net proceeds from the stock and note offerings to repurchase a portion of its outstanding 6.75% Convertible Senior Notes due 2030 and for general corporate purposes. The company highlights significant risks including potential dilution from this equity raise and existing anti-dilution protections in preferred and other securities, continued operating losses and going-concern uncertainty, and the possibility that neither the stock offering nor the concurrent note offering and related repurchases are completed.
