Nelson Avery H III 4

What Happened

• Nelson Avery H. III, Executive Vice President & COO of Corning (GLW), had equity awards convert/exercise on April 15, 2026. A total of 59,011 share-equivalents were converted (41,173 + 17,838). Of those, 28,740 shares were withheld/disposed to satisfy tax withholding at $168.27 per share, totaling $4,836,080. The awards show a $0 exercise price (derivative conversion of RSUs/PSUs).
• This was not an open-market sale for investment reasons but a routine conversion/vesting event with a sell-to-cover (tax withholding) of shares.

Key Details

• Transaction date: April 15, 2026; Form 4 filed April 16, 2026 (timely).

• Tax withholding/payment (code F): 28,740 shares withheld at $168.27 each = $4,836,080.
• Net shares issued to insider after withholding: 59,011 - 28,740 = 30,271 shares (newly received shares); total shares owned after transaction not reported in this filing.
• Relevant footnotes: awards are RSUs/PSUs that vest/convert on April 15, 2026 (see F10 and F9); some PSU/RSU tranches have later vesting dates per other footnotes.
• Transaction codes: M = exercise/conversion of derivative; F = shares withheld to pay tax liability.

Context

• This was a vesting/conversion event (restricted stock units and performance share units converting to common stock). The withheld shares represent a standard sell-to-cover for taxes, not a discretionary open-market sale. Such transactions reflect routine tax/payment mechanics rather than a direct signal of the insider’s view on the stock.
