Patrick A. Kriegshauser: trading record in brief

Filings by Patrick A. Kriegshauser span 2 companies, the busiest being Core Natural Resources, Inc. and Arch Resources, Inc. In total, 6 filings cover trades dated from 9 February 2024 to 17 February 2026.

On the market, this insider has only sold: 1 sale, €198k in total. The rest of the record consists of 3 share grants and 1 option exercise.

Most recently, on 19 February 2026, the filings show a share grant in Core Natural Resources, Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
