Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay.

The data flag 1 purchase as part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The last insider purchase was made public on 16 December 2025, 305 days ago. Typically, a trade is published a median of 5 days after it takes place. The regulation allows three business days to notify a trade (MAR article 19). Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.

With 9 filings in twelve months, the company is more active than the median of 6 filings across the 316 companies we follow on the same exchange. Looking back to 2021, when coverage begins, insiders filed 34 purchases and 27 sales.
