Stuart D. Porter

Stuart D. Porter has filed trades across 4 companies (mainly through SEC (Form 4)), most often in AirJoule Technologies Corp., ChampionX Corp and KLX Energy Services Holdings, Inc. Over a trading history stretching from 15 November 2021 to 10 July 2026, the count stands at 18 filings.

The open-market record is one-sided, with 2 purchases worth €505k and not one sale. 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 7 share grants and 4 option exercises. In 2026 alone, the filings show 1 purchase and no sales.

Most recently, on 14 July 2026, the filings show an option exercise in GameSquare Holdings, Inc. The last purchase on record was published on 20 January 2026, which is 271 days ago. Typically, a trade is published a median of 4 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
