Tia L. Bush: trading record in brief
Tia L. Bush (senior executive) discloses dealings in Centessa Pharmaceuticals plc to SEC (Form 4). Over a trading history stretching from 2 June 2021 to 24 June 2026, the count stands at 25 filings.
The open-market side counts 2 purchases for €60k alongside 3 sales for €179k. Sales outweigh purchases by €120k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 15 share grants and 4 option exercises.
The record was last updated on 24 June 2026 with a transaction in Centessa Pharmaceuticals plc. The last insider purchase was made public on 18 November 2021, 1,795 days ago. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
