Kooij Louise Frederika 4

What Happened

• Louise Frederika Kooij, Chief Accounting Officer of NewAmsterdam Pharma (NAMS), exercised stock options to acquire a total of 72,572 shares (38,172 on Jan 23 and 34,400 on Jan 26) at an exercise price of $10.90 per share (total exercise cost $791,035).
• She sold all 72,572 shares in a series of open-market transactions on Jan 23 and Jan 26, 2026, for aggregate gross proceeds of $2,415,843 (sales executed at weighted-average prices shown below). The filing also records the option conversion/disposition entries (reported at $0) associated with the exercises.
• This sequence—exercising options and immediately selling the resulting shares—is effectively a cashless exercise/monetization of vested options (commonly used to cover exercise costs and taxes) and is generally considered routine rather than a directional bet.

Context

• For retail investors: exercises followed by immediate sales are common for executives exercising vested options to cover exercise price and tax withholding; they do not necessarily signal a change in the officer’s view of the company.
• The filing shows an officer monetizing vested options rather than an open-market purchase (which is typically considered a stronger bullish signal).
