The open-market side counts 1 purchase for €352k alongside 1 sale for €204k. Taken together, the purchases exceed the sales by €148k. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 21 share grants. Since January 2026: no purchases and 1 sale on the market.

The record was last updated on 10 June 2026 with a share grant in Ambiq Micro, Inc. The latest purchase dates back some time: it was published 2,901 days ago, on 13 November 2018. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. Section 16 rules allow two business days to file each Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
