Per Business Quant data, United Health Products insiders hold 1.1Mn shares in total based on their latest Form 4 filings, or 0.42% of the 261.59Mn shares outstanding; that total is unchanged from the end of Q2 2026 and Q3 2025.
| # | Insider | Position | Direct | Indirect | Total | Share of Insiders | Last Filed |
|---|---|---|---|---|---|---|---|
| 1 | Brian David Thom | Chief Executive Officer | 3,308,000 | 0 | 3,308,000 | 100.0% | 09 Jan, 2025 |
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.
