TILLMAN MICHAUNE D 4

What Happened
Michaune D. Tillman, SVP and General Counsel of Corning Incorporated (GLW), was granted two awards of performance share units (PSUs) on February 4, 2026: 6,848 PSUs and 8,592 PSUs, for a total of 15,440 PSUs. The Form 4 reports these as derivative acquisitions at $0.00 per unit (awards), so the filing records $0 cash consideration; actual value will depend on Corning’s future stock price when/if the PSUs convert to shares.

Context
PSUs are performance-based long-term equity awards: they were "earned" because the Compensation Committee determined fiscal 2025 performance targets were met, but they remain restricted and will convert to actual shares only if/time when vesting conditions (including continued employment) are satisfied on the listed vest dates. These awards are compensation, not open-market purchases or sales, so they do not directly signal buying or selling intent by the insider; their ultimate monetary value depends on Corning's stock price at vesting.
