Comment

This Amendment No. 1 to Schedule 13D (this "Amendment No. 1") amends and supplements the Schedule 13D filed with the U.S. Securities and Exchange Commission on September 29, 2026 (the "Original Schedule 13D," and together with this Amendment No. 1, the "Schedule 13D") by PMGC Holdings Inc. ("PMGC"), NorthStrive Sponsor I LLC (the "Sponsor") and Georgiy Kovalyov (collectively, the "Reporting Persons"), relating to the Class A Ordinary Shares, par value $0.0001 per share (the "Class A Ordinary Shares"), of NorthStrive Acquisition Corp I., a Cayman Islands exempted company (the "Issuer"). This Amendment No. 1 is being filed to report that, on October 20, 2026, with retroactive effect to October 3, 2026, the Sponsor forfeited and surrendered to the Issuer, for cancellation and for no consideration, 325,607 Class B ordinary shares of the Issuer, par value $0.0001 per share (the "Class B Ordinary Shares"), pursuant to Section 1.4.1 of the Underwriting Agreement, dated August 17, 2026, between the Issuer and D. Boral Capital LLC, on behalf of itself and as representative of the several underwriters named therein (the "Underwriting Agreement"), as amended by Amendment No. 1 to the Underwriting Agreement, dated as of October 8, 2026 ( "UA Amendment"). The forfeiture was required because the underwriters' over-allotment option expired unexercised on October 3, 2026, and the UA Amendment allocates the aggregate 629,998-share forfeiture required by Section 1.4.1 of the Underwriting Agreement pro rata among all Initial Shareholders based on their respective holdings of Initial Shares. As a result of the forfeiture, the Reporting Persons' aggregate beneficial ownership of Class A Ordinary Shares has decreased, as reflected on the cover pages hereto and in Items 2 and 5 below. Except as expressly amended and supplemented by this Amendment No. 1, all other information in the Original Schedule 13D is incorporated by reference herein and remains unchanged. Capitalized terms used but not defined in this Amendment No. 1 have the meanings ascribed to them in the Original Schedule 13D.

Purpose of transaction

Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following: The Reporting Persons acquired the securities described herein for investment purposes. The Reporting Persons may engage in discussions with the Issuer's management, board of directors, stockholders, and other interested parties concerning potential strategic transactions, including possible merger and acquisition opportunities. The Reporting Persons may from time to time make introductions or otherwise facilitate discussions between the Issuer and third parties regarding such potential opportunities. The Reporting Persons are in discussions with third parties that may result in any of the actions described in clauses (a) through (j) of Item 4 of Schedule 13D; however, there are currently no definitive agreements to undertake such actions. Additionally, the Reporting Persons may continue to review and consider other opportunities that may present themselves from time to time, depending on various factors, including the Issuer's financial position, the price level of the securities, conditions in the securities markets, general economic and industry conditions, or other factors. On October 20, 2026, with retroactive effect to October 3, 2026, the Sponsor forfeited and surrendered to the Issuer, for cancellation and for no consideration, 325,607 Class B Ordinary Shares pursuant to Section 1.4.1 of the Underwriting Agreement, as amended by the UA Amendment. The forfeiture was required because the underwriters' over-allotment option expired unexercised on October 3, 2026. The UA Amendment, among other things, allocates the aggregate 629,998-share forfeiture required by Section 1.4.1 of the Underwriting Agreement pro rata among the Initial Shareholders in proportion to the number of Initial Shares held by each Initial Shareholder (rather than solely to the Sponsor as originally contemplated by Section 1.4.1 of the Underwriting Agreement, consistent with the beneficial ownership disclosure in the Issuer's prospectus for the IPO). The forfeiture of the 325,607 Class B Ordinary Shares did not involve the payment of any consideration to the Sponsor or any other Reporting Person. The Reporting Persons do not have any present plans or proposals, other than as described in this Item 4 and the Original Schedule 13D, that relate to or would result in any of the actions set forth in clauses (a) through (j) of Item 4 of Schedule 13D, although they reserve the right to formulate such plans or proposals in the future.
