Jonas Grossman: trading record in brief
Jonas Grossman (board member) discloses dealings in 6 companies, chiefly Renovacor, Inc., BiomX Inc. and Dragonfly Energy Holdings Corp. We count 10 filings; the first trade dates from 26 July 2021 and the latest from 28 August 2026.
The open-market side counts 4 purchases for €6.8M alongside 2 sales for €2,331. The totals do not cover 2 filings with an undisclosed amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 1 share grant. Since January 2026: 1 purchase and no sales on the market.
Clusters matter here: 1 out of 4 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.
Most recently, on 28 August 2026, the filings show an open-market purchase worth €1.7M in Rainier Acquisition Corp. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. Section 16 rules allow two business days to file each Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
