**Item 3.03 Material Modification to Rights of Security Holders.**

To the extent required by Item 3.03 of Form 8-K, the information contained in Item 5.03 of this Current Report on Form 8-K is incorporated herein by reference.

**Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.**

On December 15, 2025, 374Water Inc. ("**374Water**" or the "**Company**") filed a Certificate of Amendment of the Amended and Restated Certificate of Incorporation (the "**Certificate of Amendment**") with the Secretary of State of the State of Delaware to effect a 1-for-10 reverse stock split (the "**Reverse Stock Split**") of the issued and outstanding shares of the Company's Common Stock (the "**Common Stock**"). The Certificate of Amendment will take effect as of 12:01 a.m. Eastern Time on December 26, 2025 (the "**Effective Time**").

Upon the Effective Time of the Certificate of Amendment with the Secretary of State of the State of Delaware, each ten (10) shares of Common Stock issued immediately prior to the Effective Time shall, automatically and without any action on the part of the respective holders thereof, be reclassified and combined into one (1) share of Common Stock. No fractional shares shall be issued. In lieu thereof, stockholders of record who otherwise would be entitled to receive fractional shares will be instead entitled to an amount in cash (without interest or deduction) equal to the fraction of one share to which such stockholder would otherwise be entitled, multiplied by the closing price of our common stock on Nasdaq on the date of the Effective Time. Except for the right to receive the cash payment in lieu of fractional shares, stockholders will not have any voting, dividend or other rights with respect to the fractional shares they would otherwise be entitled to receive. The cash payment may be paid by check, wire, deposit into an existing brokerage account or some other means depending on how the shares are held.. The Reverse Stock Split will affect all shares of the Company's Common Stock outstanding, or held as treasury stock, immediately prior to the effective time of the Reverse Stock Split, as well as the number of shares of Common Stock available for issuance under the Company's equity incentive plans. In addition, the Reverse Stock Split will result in a reduction in the number of shares of Common Stock issuable upon the exercise of stock options, restricted stock units and warrants outstanding immediately prior to the effectiveness of the Reverse Stock Split with a corresponding increase in the exercise price per share applicable to such stock options. The total number of shares of capital stock that we are authorized to issue pursuant to the Company's Amended and Restated Certificate of Incorporation will not be affected by the Reverse Stock Split and will remain at 1,050,000,000 shares, consisting of 1,000,000,000 shares of common stock and 50,000,000 shares of preferred stock.

The Company's Common Stock is scheduled to begin trading on a post-Reverse Stock Split basis at the market open on December 26, 2025, under the Company's existing trading symbol "SCWO." The new CUSIP number for the Common Stock following the Reverse Stock Split is 88583P 203. The par value per share of the common stock will remain unchanged at $0.0001.

The foregoing brief description of the Certificate of Amendment is qualified in its entirety by the full text of the Certificate of Amendment, filed as Exhibit 3.1 hereto and incorporated herein by reference.

**Item 5.07 Submission of Matters to a Vote of Security Holders.**

At a special meeting of stockholders (the "**Special Meeting**") of 374Water held on December 15, 2025, the following proposals were submitted to the stockholders of 374Water:

· Proposal 1: To approve an amendment to the Company's Amended and Restated Certificate of Incorporation, to, at the discretion of the Company's Board of Directors, effect a reverse stock split with respect to the Company's issued and outstanding common stock, at a ratio of 1-for-8 to 1-for-20, with the ratio within such range to be determined at the discretion of the Company's Board of Directors (or any of its delegated authorized persons) without further approval or authorization of our stockholders (the "**Reverse Stock Split Proposal**").

· Proposal 2: To authorize an adjournment or adjournments of the Special Meeting to a later date or dates, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes in favor of the Reverse Stock Split Proposal (the "**Adjournment Proposal**").

At the close of business on October 24, 2025, the record date for the Special Meeting, 169,248,799 shares of the Company's common stock, par value $0.0001 per share, were issued and outstanding and entitled to vote at the Special Meeting.

The number of votes cast for, against and abstaining in respect of the Reverse Stock Split Proposal is set forth below:

---

| | | |
|:---|:---|:---|
| **Votes For** | **Votes Against** | **Votes Abstaining** |
| 99,559,608 | 30,352,738 | 1,411,103 |

---

Since there were sufficient votes at the time of the Special Meeting to approve the Reverse Stock Split Proposal, the Adjournment Proposal was not called for at the Special Meeting.

## Exhibit 3.1

**EXHIBIT 3.1**

**CERTIFICATE OF AMENDMENT TO THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF 374WATER INC.**

374Water Inc., a Delaware corporation (the "Corporation"), hereby certifies that:

1. Article Six of the Amended and Restated Certificate of Incorporation of the Corporation, as amended to date, is hereby amended by adding the following new paragraph at the end of such article:

Reverse Stock Split. Upon the effectiveness of the Certificate of Amendment to the certificate of incorporation first inserting this sentence (the "Reverse Split Effective Time"), each eight (8) to twenty (20) issued shares of Common Stock as of the Reverse Stock Split Effective Time shall automatically, and without action on the part of the Corporation or the stockholders, be combined into one (1) validly issued, fully paid and non-assessable share of Common Stock, without effecting a change to the par value per share of Common Stock, with the exact ratio within, and inclusive of, eight (8) to twenty (20) shares to be determined by the Board of Directors of the Corporation prior to the Reverse Split Effective Time and publicly announced by the Corporation (such combination of shares, the "Reverse Stock Split"). The Reverse Stock Split shall occur automatically, without any action by the holders of the shares of Common Stock and whether or not any certificates representing such shares have been surrendered to the Corporation, and each certificate that immediately prior to the Reverse Split Effective Time represented shares of Common Stock, shall thereafter, automatically and without presenting the same for exchange, represent that number of shares of Common Stock into which the shares of Common Stock represented by such certificate shall have been combined, subject to any elimination of fractional interests; provided that the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable as a result of the Reverse Stock Split unless the existing certificate(s) evidencing the applicable shares of Common Stock prior to the Reverse Stock Split are surrendered to the Corporation (or unless the holder thereof notifies the Corporation that such certificate(s) have been lost, stolen or destroyed and executes a lost certificate affidavit and agreement reasonably acceptable to the Corporation, which may include a requirement to post a bond, to indemnify the Corporation against any claim that may be made against the Corporation on account of such alleged loss, theft or destruction). Each book entry position that immediately prior to the Reverse Stock Split Effective Time represented issued shares of Common Stock shall thereafter represent the number of shares of Common Stock into which the shares of Common Stock represented by such book entry position has been combined pursuant to the Reverse Stock Split, subject to any elimination of fractional interests. The Reverse Stock Split shall also apply to any outstanding securities or rights convertible into, or exchangeable or exercisable for, Common Stock of the Corporation, and adjustments to such securities or rights (including the treatment of any fractional shares resulting from such adjustments) shall be made in accordance with the terms of the applicable agreements governing such securities or rights, including but not limited to the Corporation's 2021 Equity Incentive Plan and applicable warrant agreements.

2. The foregoing amendment was duly adopted in accordance with Section 242 of the Delaware General Corporation Law.

3. Prior to this Certificate of Amendment becoming effective, the Board of Directors of the Corporation determined that each ten (10) issued shares of Common Stock be combined into one (1) validly issued, fully paid and non-assessable share of Common Stock.

4. This Certificate of Amendment shall become effective at 12.01 a.m., Eastern Time, on December 26, 2025.

2<br>

IN WITNESS WHEREOF, 374Water Inc. has caused this Certificate of Amendment to be executed by the undersigned officer, on this the 15<sup>th</sup> day of December, 2025.
