SCHEDULE 13D

Explanatory Statement

This Amendment No. 2 (“Amendment No. 2”) amends and supplements the Schedule 13D originally filed on June 30, 2023, as amended from time to time (the “Schedule 13D”) relating to the ordinary shares (the “Ordinary Shares”), nominal value €0.12 per share, of NewAmsterdam Pharma Company N.V., a public limited liability company (naamloze vennotschap) incorporated under the laws of the Netherlands (the “Issuer”). Capitalized terms used herein and not otherwise defined shall have the same meanings ascribed to them in the Schedule 13D.

Item 2 of the Schedule 13D is hereby amended and restated as follows:

The Schedule 13D is being jointly filed by:

(i) Forbion Capital Fund IV Coöperatief U.A., a Dutch co-operative association (“Forbion IV”);

(ii) Forbion IV Management B.V., a Dutch private company with limited liability (“Forbion IV Management”), the sole director of Forbion IV;

(iii) Forbion Growth Opportunities Fund I Coöperatief U.A., a Dutch co-operative association (“Forbion Growth I”);

(iv) Forbion Growth Management B.V., a Dutch private company with limited liability (“Forbion Growth Management”), the sole director of Forbion Growth I;

(v) ForGrowth NAP B.V., a Dutch private company with limited liability (“ForGrowth”);

The foregoing parties are sometimes referred to collectively herein as the “Reporting Persons”.

The Ordinary Shares that may be deemed to be beneficially owned by Forbion Growth I and Forbion IV are held through ForGrowth. ForGrowth is a joint investment vehicle wholly owned by Forbion Growth I and Forbion IV.

The Ordinary Shares that may be deemed to be beneficially owned by Forbion IV, Forbion Growth I and ForGrowth are held partially through NAP PoolCo B.V. (“PoolCo”). PoolCo is a Dutch limited liability company that holds Ordinary Shares on behalf of its shareholders. The governing documents of PoolCo vest voting and investment control over the Ordinary Shares held by PoolCo in PoolCo’s shareholders and, as a result, PoolCo disclaims beneficial ownership of such Ordinary Shares.

The Business address and principal office address of the Reporting Persons is Gooimeer 2-35, 1411 DC Naarden, The Netherlands. The principal business of each of the Reporting Persons is capital investing on behalf of its investors.

During the last five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

During the last five years, none of the Reporting Persons has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violation of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
