(2) Percentage in row 13 calculated based on 39,692,026 shares of common stock, par value $0.0001 per share, outstanding as of January 30, 2026, as reported in the Form 10-Q for the quarterly period ended December 31, 2025, of Lantronix, Inc.

**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Common Stock

**(b) Name of Issuer:**
LANTRONIX INC

**(c) Address of Issuer's Principal Executive Offices:**
48 Discovery, Suite 250, Irvine, CA, 92618

This Amendment No. 3 to Schedule 13D (this "Amendment") relates to the shares of common stock, $0.0001 par value per share (the "Common Stock"), of Lantronix, Inc., a Delaware corporation (the "Issuer") that are or may be deemed to be beneficially owned by the Reporting Persons (as defined below) and amends certain information included in the Schedule 13D filed by the Reporting Persons with the Securities and Exchange Commission on June 2, 2025 (the "Original Schedule 13D"), Amendment No.1 to the Original Schedule 13D filed by the Reporting Persons with the Securities and Exchange Commission on July 1, 2025 (the "Amendment No. 1"), and Amendment No. 2 to the Original Schedule 13D filed by the Reporting Persons with the Securities and Exchange Commission on January 30, 2026 (the "Amendment No. 2").

**Item 4. Purpose of Transaction**

As described in the Original Schedule 13D, the Reporting Persons originally acquired the shares in the Issuer because they believed the Shares were materially undervalued and represented an attractive investment opportunity. As a result of the foregoing and as disclosed in detail in Item 4 of the Original Schedule 13D, the Reporting Persons considered taking one or more actions described in subjections (a) through (j) of Item 4 of Schedule 13D, and intended to seek to replace a majority of the current members of the Board of the Issuer with candidates that were committed to an expedited return of shareholders' capital through a sale of the Issuer by running a competing proxy statement at the Issuer's 2025 Annual Meeting of Stockholders.

Subsequent to the filing of the Original Schedule 13D and as described in detail in Amendment No. 1, the Reporting Persons engaged in discussions with the Issuer, and the parties have agreed to resolve their differences with respect to this matter by entering into a Cooperation Agreement dated June 24, 2025 (the "Cooperation Agreement").  A copy of the Cooperation Agreement was filed as Exhibit 1 to Amendment No. 1.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis, and depending on various factors, may in the future take such actions with respect to their investment in the Issuer as they deem appropriate, subject to compliance with the terms of the Cooperation Agreement.

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

**(a)**
The information set forth in the cover pages of this Schedule 13D is hereby incorporated by reference in this Item 5.  As of the date hereof the Reporting Persons beneficially own an aggregate of 1,691,425 shares of the Issuer's Common Stock, representing 4.26% of the outstanding shares.

**(b)**
The information set forth in the cover pages of this Schedule 13D is hereby incorporated by reference in this Item 5.

The Reporting Persons may be deemed to constitute a group pursuant to Rule 13d-5(b), in which case each of the Reporting Persons could be deemed to beneficially own all the shares of Common Stock held by the other Reporting Persons; however, each of the Reporting Persons disclaims beneficial ownership of the shares of Common Stock held by the other Reporting Persons except to the extent of their pecuniary interest therein (if any).

**(c)**
Information concerning transactions in the Shares effected by the Reporting Persons since the filing of Amendment No. 2 on January 30, 2026 is set forth in Exhibit 1 hereto and is incorporated herein by reference. All of the transactions in Shares listed hereto were effected in the open market.

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

The Reporting Persons' discussions of their views about the Issuer, and their entry into the Cooperation Agreement, may result in the Reporting Persons being deemed to be acting together for the purpose of acquiring, holding, voting or disposing of the Issuer's securities for purposes of Rule 13d-5(b).

The disclosure in Item 4 relating to the Cooperation Agreement is incorporated herein by reference.

Except as described herein, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) between or among any of the Reporting Persons and any other person with respect to any securities of the Issuer.
