## Insider sales (SEC Form 4, open-market, last ~7 months)
0 of 3 under a Rule 10b5-1 trading plan (scheduled in advance). Unplanned sales were timed by the insider.
| Trade date | Insider | Role | Shares | Value | % of holdings sold | 10b5-1 plan | Insider type |
|---|---|---|---|---|---|---|---|
| 2026-06-15 | Szlak Daniel | Chief Financial Officer | 7,381 | $209K | 100% | No | Too little history (no open-market trades in 2023–2025) |
| 2026-05-25 | Tavares De Sousa Roberval | Engineering Officer | 5,900 | $170K | 98.7% | No | Too little history (no open-market trades in 2023–2025) |
| 2026-05-21 | Tavares De Sousa Samanta I.S. | Inst. Rel. & Sustain. Officer | 5,700 | $163K | 99.3% | No | Too little history (no open-market trades in 2023–2025) |
% of holdings sold = shares sold ÷ (shares sold + all holdings the insider reported on that Form 4, direct and through trusts).
Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.
