Dennis Cho

Dennis Cho discloses dealings in Twist Bioscience Corp to SEC (Form 4). The record holds 95 filings, for trades running from 13 September 2021 to 2 October 2026.

Both buying and selling appear: 1 purchase worth €120k, against 63 sales worth €7.3M. The amount is not disclosed for 3 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 31 share grants. Since January 2026: no purchases and 17 sales on the market.

The latest filing, published on 5 October 2026, reports an open-market sale of €1.6M in Twist Bioscience Corp. The last purchase on record was published on 12 May 2023, which is 1,255 days ago. 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. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
