John W. Childs

John W. Childs (senior executive) discloses dealings in 4 companies, chiefly Biohaven Ltd., Veradermics, Inc and Mattress Firm Holding Corp. Between 3 February 2016 and 12 August 2026, the trades on record add up to 35 filings.

In open-market terms, that means 22 purchases worth €121.1M on one side and 3 sales worth €9.3M on the other. The amount is not disclosed for 2 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 4 share grants and 1 option exercise. 2026 to date brings 2 purchases and 3 sales.

In size, the median ticket on the buying side is €1.4M. Clusters matter here: 12 out of 20 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.

The record was last updated on 14 August 2026 with an open-market sale (€1.4M) in Veradermics, Inc. The last insider purchase was made public on 9 March 2026, 223 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
