Derrick Sung: trading record in brief
Derrick Sung (finance chief) discloses dealings in 2 companies, chiefly Pulmonx Corp and Minerva Surgical Inc. Between 1 June 2021 and 1 December 2025, the trades on record add up to 15 filings.
No open-market purchase appears, only 11 sales worth €242k. Outside the open market, there are 3 share grants and 1 option exercise.
The newest entry dates from 3 December 2025: a share grant, in Pulmonx Corp. The median gap between a trade and its publication by SEC (Form 4) is 2 days. 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. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
