Corning director reports stock and deferred RSU holdings update

Corning Inc. director reported equity holdings and awards in this insider ownership update.

Rhea-AI Filing Summary

Corning Inc. director reported equity holdings and awards in this insider ownership update. The earliest reported transaction date is 12/31/2025, and the filing shows both common stock and restricted stock units (RSUs).

The director holds 6,938 shares of Corning common stock directly. In addition, the filing lists multiple RSU positions that each represent a contingent right to receive one share of Corning common stock, including awards granted as an annual equity retainer and under the Non-Employee Directors' Deferred Compensation Plan.

The RSUs generally convert into common stock and are distributed only on a specific deferred date chosen by the director or upon termination of service as a Corning director, so these units function as deferred equity compensation rather than immediate stock ownership.
