Andrew Booth: trading record in brief
Andrew Booth (finance chief) discloses dealings in AbCellera Biologics Inc. to SEC (Form 4). We count 10 filings; the first trade dates from 7 June 2021 and the latest from 14 August 2026.
The open-market side counts 5 purchases for €1.7M alongside 1 sale for €25.1M. Netting one side against the other leaves €23.4M of net selling. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 4 option exercises. Since January 2026: 2 purchases and no sales on the market.
The median purchase comes to €333k. Clusters matter here: 5 out of 5 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.
Most recently, on 14 August 2026, the filings show an open-market purchase worth €333k in AbCellera Biologics Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
