Market trades split into 1 purchase (€110k) and 4 sales (€16.6M). On balance, insiders were net sellers of €16.5M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 21 share grants and 3 option exercises. So far in 2026, the count stands at no purchases and 2 sales.

The latest filing, published on 18 September 2026, reports a transaction in Planet Labs PBC. The last purchase on record was published on 23 December 2021, which is 1,760 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
