Gullo Michelle L 4

What Happened

• Michelle L. Gullo, Senior Vice President & Chief Human Resources Officer at Corning (GLW), was credited with performance share units (PSUs) earned for fiscal 2025 and reported several related transactions on Feb 4, 2026.
• Total PSUs credited: 10,839 (grants of 2,740; 3,340; and 4,759 PSUs). Some PSUs were converted/treated as share equivalents and 386 shares were surrendered/withheld to satisfy tax withholding at $109.69 per share, yielding $42,340 (reported as a disposition).
• The awards and conversions are derivative transactions (PSUs/award conversions), not open-market purchases.

Key Details

• Transaction date: February 4, 2026; Form 4 filed February 6, 2026 (appears timely).
• Awards granted/acquired (derivative): 2,740; 3,340; 4,759 PSUs — total 10,839 PSUs, acquisition price $0.00 (derivative awards).
• Exercise/conversion and withholding: 98, 119 and 169 shares (total 386) converted/treated and then disposed/withheld to cover taxes at $109.69/share for a total reported value of $42,340.
• Relevant footnotes: PSUs represent contingent rights to one share each; PSUs were earned per the Compensation Committee for FY2025 under the 2023–2025 agreements. Vesting/conversion to common stock is subject to service-based vesting and occurs on: April 15, 2026 (2023 award), April 15, 2027 (2024 award), and April 14, 2028 (2025 award). Withholding/surrender was to satisfy tax liabilities under those agreements.
• Transaction codes: A = award/grant (PSU), M = exercise/conversion of derivative, F = payment of exercise price or tax liability (share withholding).

Context

• These are compensation-related derivative transactions: PSUs were earned and remain restricted until their scheduled vesting dates. The 386-share disposition was a routine tax-withholding action (shares surrendered/withheld), not an open-market sale indicating a directional view. Exercises/conversions at $0.00 reflect conversion of PSUs into underlying share equivalents for vesting/tax purposes.
