Soluna Holdings, Inc. filed a prospectus supplement for an at-the-market offering of its common stock with an aggregate offering price of up to $87,650,000. The offering is being made under an existing At the Market Offering Agreement dated April 29, 2025 with H.C. Wainwright & Co., LLC, using a previously filed Form S-3 shelf registration and related ATM prospectus.
The company states that this new supplement must be read together with its prior ATM prospectus documents. Soluna has already sold 13,680,483 shares of common stock for aggregate gross proceeds of approximately $12.3 million under the same Sales Agreement. A legal opinion from Brownstein Hyatt Farber Schreck, LLP regarding the validity of the shares is included as an exhibit.
The company is updating its at-the-market common stock offering of up to $87,650,000 under its existing S-3 shelf. The supplement reports that, as of September 23, 2025, its public float was $98.5 million, based on 47,036,233 shares held by non-affiliates at a price of $2.10 per share, so it is no longer subject to the Form S-3 General Instruction I.B.6 sales limitations for this program.
At a reference price of $2.10 per share, fully using the $87,650,000 capacity would mean issuing about 41.7 million shares, but as of September 22, 2025 the company had approximately 4.3 million shares of common stock authorized and available for future issuance, which constrains how many shares can currently be sold under the Sales Agreement.
