| # | Insider | Position | Direct | Indirect | Total | Share of Insiders | Last Filed |
|---|---|---|---|---|---|---|---|
| 1 | Boer Daniel Anton De | Chief Executive Officer | 500,000 | 0 | 500,000 | 62.5% | 03 Aug, 2026 |
| 2 | Bart Filius | Director | 300,000 | 0 | 300,000 | 37.5% | 21 Jul, 2026 |
Each row is that insider’s most recently reported position, from Form 4 filings over the last 60 months — which is why this total does not tie to the quarterly series above, where a quarter counts only the insiders who filed in it. Shares held through a fund or institutional portfolio are counted on the institutional ownership page instead.
