Robert Chess: trading record in brief
Robert Chess (board member) discloses dealings in 2 companies, chiefly Twist Bioscience Corp and Nektar Therapeutics. Over a trading history stretching from 12 May 2021 to 23 September 2026, the count stands at 30 filings.
Sales make up the whole of the open-market record (14 sales, €4.0M). Besides market trades, the filings include 8 share grants and 7 option exercises. So far in 2026, the count stands at no purchases and 2 sales.
On 25 September 2026 came the latest disclosure, a share grant in Nektar Therapeutics. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a 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.
