CAO Louise Kooij sells 65,000 NAMS shares at $35.69 under 10b5-1 plan; retains 24,353 non-derivative shares plus 148,149 derivative holdings

Louise Frederika Kooij, Chief Accounting Officer, sold 65,000 shares (65.0K shares) valued at $2,319,850.00 ($2.3M) on 2026-05-26 at $35.69 per share as part of a pre-arranged 10b5-1 trading plan. After this scheduled sale, she retains 24,353 shares (24.4K shares) in non-derivative holdings, with an additional 148,149 shares held through derivative securities (80,015 options and 68,134 options), meaning her overall position remains substantial. Her prior five trades at NAMS show a pattern of sales with 30-day returns ranging from +4.7% to +11.5% followed by 90-day declines ranging from -5.9% to -11.2%, suggesting post-sale price weakness has historically occurred within her trading window at this ticker. The company reports negative net income of $-48,441,000.00 ($-48.4M), annual revenue decline of -50.6%, and current revenue of only $3,040,000.00 ($3.0M), indicating material operational challenges that may inform the scheduled nature of this divestment.
