Filings by Mary D. Petryszyn span 3 companies, the busiest being Northrop Grumman Corp /DE/, Woodward, Inc. and Karman Holdings Inc. Over a trading history stretching from 10 February 2020 to 1 October 2026, the count stands at 30 filings.

In open-market terms, that means 1 purchase worth €16k on one side and 8 sales worth €2.9M on the other. Sales outweigh purchases by €2.9M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 12 share grants and 8 option exercises. 2026 to date brings 1 purchase and no sales.

Most recently, on 2 October 2026, the filings show a share grant in Woodward, Inc. The last insider purchase was made public on 18 September 2026, 51 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. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
