CitroTech Inc.

**(c) Address of Issuer's Principal Executive Offices:**
6400 S. Fiddlers Green Cir, Suite 300, Greenwood Village, CO, 80111

This Amendment No. 3 to Schedule 13D amends and supplements the statement on Schedule 13D originally filed with the United States Securities and Exchange Commission ("SEC") on March 24, 2025 (as subsequently amended, the "Schedule 13D"). Capitalized terms used but not defined herein shall have the meanings attributed to them in the Schedule 13D.

**Item 4. Purpose of Transaction**

The information in Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:

On May 28, 2026, the Issuer and BoltRock Holdings LLC ("BoltRock") entered into a Stock Exchange and Stockholders Agreement (the "Agreement"), pursuant to which BoltRock exchanged 302,526 shares of Series A Preferred Stock for 103,558 shares of Series C Convertible Preferred Stock for no additional consideration (the "Series A Exchange"). The Series A Exchange closed on May 28, 2026.

Among other things, the Agreement also provides that: (i) for so long as BoltRock beneficially owns at least 10% of the Issuer's issued and outstanding common stock ("Common Shares"), assuming the conversion of all outstanding derivative securities BoltRock holds into Common Shares, BoltRock has the right, but not the obligation, to appoint or replace, as applicable, one member of the Issuer's board of directors (the "Board") and any committee of the Board (and, if BoltRock has not so appointed a member of the Board, BoltRock instead has the right to appoint a Board observer); (ii) the Issuer may not, without the prior written consent of BoltRock (a) for 12 months following May 28, 2026, hire or terminate any individual to a C-suite level or equivalent executive position or (b) enter into any transaction, agreement or arrangement, or any amendment or termination of or waiver under any transaction, agreement or arrangement between or among the Issuer, TC Special Investments, LLC or any of their respective affiliates or any director, officer or employee thereof, as applicable; (iii) the Issuer must use commercially reasonable efforts to facilitate any sale of equity securities of the Issuer by BoltRock pursuant to Rule 144 under the Securities Act of 1933, as amended, including causing the removal of any restrictive legend or similar restriction on the Issuer securities held by BoltRock or any of its affiliates; (iv) the Issuer must use commercially reasonable efforts to file a registration statement with the SEC registering the resale of certain equity securities of the Issuer held by BoltRock as may be requested by BoltRock; and (v) for 18 months following May 28, 2026, BoltRock may not sell any shares of Series C Convertible Preferred Stock acquired from the Exchange without the Issuer's prior written consent, subject to certain limited exceptions.

The above description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the agreement, which is filed as an exhibit hereto and incorporated herein by reference.

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

**(a)**
The information in Item 5 of the Schedule 13D is hereby amended and restated as follows:

The Reporting Persons have beneficial ownership of 4,528,936 shares of Common Shares, which consists of (i) 3,357,467 Common Shares, (ii) 664,107 Common Shares issuable upon the conversion of 199,232 Series C Shares and (iii) 507,362 Common Shares issuable upon the exercise of certain warrants held by BoltRock. The percentage of beneficial ownership is approximately 19.2% of the outstanding Common Shares. The percentage was calculated based on 22,357,412 Common Shares outstanding as disclosed in the Issuer's Quarterly Report on Form 10-Q filed on May 15, 2026, (ii) 664,107 Common Shares issuable upon the conversion of 199,232 Series C Shares held by BoltRock and (iii) 507,362 Common Shares issuable upon the exercise of certain warrants held by BoltRock.
