Every 424B that 374Water Inc. (SCWO) has filed with the SEC in the last 12 months is listed below, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 424B covers the supplement that carries the terms of a priced offering, so if you follow SCWO and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full SCWO filings page.
374Water Inc. is establishing an at-the-market equity program under a shelf registration, allowing sales of up to $50,000,000 of common stock through Robert’s & Ryan Inc. as sales agent. Robert’s & Ryan will receive a commission of up to 3.0% of gross proceeds and is deemed an underwriter.
The company’s public float is approximately $27,000,000, and sales under this Form S-3 are limited by the “baby shelf” rule to no more than one-third of that value in any 12-month period while float remains below $75 million. Based on an assumed price of $2.45 per share, the company illustrates selling 20,408,163 shares, which would increase shares outstanding from 17,718,161 to up to 38,126,324 shares.
As of June 30, 2026, historical net tangible book value was $0.12 per share; on the illustrative full use of this ATM, as-adjusted net tangible book value would rise to $1.33 per share, implying dilution of $1.12 per share to new investors at the assumed offering price. Net proceeds are intended for working capital and general corporate purposes.
374Water Inc. is offering up to $50,000,000 of common stock through an at-the-market sales agreement with Lake Street Capital Markets.
The shares may be sold from time to time on The Nasdaq Capital Market under the symbol “SCWO”, with an illustrative price of $0.26 per share based on the last reported sale price on December 10, 2025. At that assumed price, 374Water could sell 192,307,692 shares, which would increase shares outstanding from 154,261,131 to up to 346,568,823.
The company currently intends to use any net proceeds primarily for working capital and general corporate purposes. Based on the illustrative sale scenario, as adjusted net tangible book value would rise from $0.04 to $0.16 per share, resulting in immediate dilution of $0.10 per share to new investors.
The company is ending a prior at-the-market stock sale program with Lake Street Capital Markets. That earlier agreement allowed sales of up to $15,100,000 of common stock over time. As of December 23, 2025, the company has sold $9.3 million of common stock under this program, and this prospectus supplement formally terminates that continuous offering as of that date. The company has entered into a new sales agreement with Lake Street for a new program, but this document focuses on closing out the old one. The company’s common stock trades on the Nasdaq Capital Market under the symbol SCWO, and the last reported sale price on December 22, 2025 was $0.24 per share.
