Both buying and selling appear: 430 purchases worth €1.7M, against 4 sales worth €4,188. Purchases outweigh sales by €1.7M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 2 option exercises. Since January 2025: 2 purchases and no sales on the market.

Half of the purchases are above €1,525 and half below. No cluster: in 295 purchases, no other insider of the company bought within 30 days.

On 29 October 2025 came the latest disclosure, an open-market purchase for €13k in Tartisan Nickel Corp. Between a trade and the moment it shows up on SEDI, the median delay is 3 days. This delay matters because a trade only becomes useful information once it is public. These figures are compiled from regulatory filings published by SEDI. They describe what insiders did and are not a recommendation.
