Birchtech Corp.: what insiders have been doing

Not one open-market sale was filed. On the buying side, 1 insider reported 1 purchase totalling €635k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Biggest ticket of the year: €635k, bought by MacPherson Richard and made public on 2 March 2026. Among those who bought: 1 chief executive.
The most recent open-market purchase was published on 2 March 2026, 230 days ago. The median gap between a trade and its publication by SEC (Form 4) is 3 days. For comparison, the SEC allows two business days to file a Form 4.
For context, the typical company on the same exchange (median of 5,458 companies) published 22 filings over the same period, against 4 filings here. Our records for Birchtech Corp. go back to 2021, with 2 purchases and no sales on the open market in total.
