**Item 1. Security and Issuer**

374Water Inc.

**(c) Address of Issuer's Principal Executive Offices:**
100 Southcenter Court, Suite 200, Morrisville, NC, 27560

**Item 4. Purpose of Transaction**

On December 10, 2025, Mr. Davis contacted Messrs. Nagar and McKnight separately to express his views regarding the current management of the Issuer, including his belief that the proposed reverse stock split described in the Issuer's definitive proxy statement on Schedule 14A filed on November 3, 2025 (the "proposed reverse stock split") is not in the best interests of the Issuer or its stockholders. After further discussion ensued among the Reporting Persons, the Reporting Persons determined to express their views to the Board of Directors of the Issuer (the "Board") via a letter to be delivered to the Board.

The Reporting Persons do not have any current plan or proposal that relates to or would result in any of the matters described in Items 4(a) - (j) of Schedule 13D, except as described in this Schedule 13D or as would occur upon, in connection with completion of, or following, any of the actions described in this Schedule 13D.

**Item 5. Interest in Securities of the Issuer**

**(a)**
The information contained in rows 11 and 13 of the cover pages of this Schedule 13D (including the accompanying comments thereto) is incorporated herein by reference. Each Reporting Person expressly disclaims beneficial ownership in the securities reported herein except to the extent such Reporting Person actually exercises voting or dispositive power with respect to such securities.

**(b)**
The information contained in rows 7 through 10 of the cover pages of this Schedule 13D (including the accompanying comments thereto) is incorporated herein by reference.

**(c)**
See Item 5 (c) correspondence

**Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.**

Except as otherwise described in this Schedule 13D, (i) there are no contracts, arrangements, understandings, or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies and, (ii) other than standard default and similar provisions contained in loan agreements, none of the securities of the Issuer beneficially owned by any Reporting Person are pledged or otherwise subject to a contingency the occurrence of which would give another person voting or investment power over such securities.
