Mark S. Wrighton

Mark S. Wrighton (board member) discloses dealings in 4 companies, chiefly Azenta, Inc., Cabot Corp and Corning INC /ny. We count 47 filings; the first trade dates from 4 April 2006 and the latest from 4 September 2025.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

Most recently, on 8 September 2025, the filings show a transaction in Corning INC /ny. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
