Stacy Durbin Nieuwoudt: trading record in brief
Stacy Durbin Nieuwoudt (board member) discloses dealings in 2 companies, chiefly Independence Contract Drilling, Inc. and ProFrac Holding Corp. The record holds 13 filings, for trades running from 19 January 2022 to 29 May 2025.
Every open-market trade on record is a purchase: 1 purchase worth €107k, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 5 share grants and 6 option exercises.
Most recently, on 2 June 2025, the filings show a share grant in ProFrac Holding Corp. The last purchase on record was published on 19 May 2022, which is 1,613 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 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.
