| # | Insider | Position | Direct | Indirect | Total | Share of Insiders | Last Filed |
|---|---|---|---|---|---|---|---|
| 1 | Eric Weisblum | Chief Executive Officer | 289 | 0 | 289 | 97.7% | 16 Dec, 2025 |
| 2 | Daniel E. Ryweck | Chief Financial Officer | 7 | 0 | 7 | 2.3% | 26 May, 2023 |
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.
