Sonja Michelle Wilkerson: trading record in brief
Sonja Michelle Wilkerson discloses dealings in Koppers Holdings Inc. to SEC (Form 4). In total, 7 filings cover trades dated from 10 September 2018 to 7 March 2025.
Not one of the filings records a straightforward purchase or sale on the market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
The newest entry dates from 11 March 2025: a transaction, in Koppers Holdings Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
