| # | Insider | Position | Direct | Indirect | Total | Share of Insiders | Last Filed |
|---|---|---|---|---|---|---|---|
| 1 | Yuk Chun Ngai | Chief Financial Officer | 687,000 | 0 | 687,000 | 99.7% | 01 Apr, 2026 |
| 2 | Wing Wai Ip | Director | 2,000 | 0 | 2,000 | 0.3% | 24 Jun, 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.
