Corning (GLW) director discloses common stock and deferred RSU awards

Rhea-AI Filing Summary

Corning Incorporated director equity holdings and awards are reported in this Form 4 for the earliest transaction date of 12/31/2025. The reporting person shows beneficial ownership of 56,888 shares of Corning common stock held directly and 107 shares held indirectly through a trust.

The filing also details several restricted stock unit (RSU) positions. One line reflects RSUs that constitute the annual equity retainer, where each RSU represents a contingent right to receive one share of Corning common stock. Other RSUs are granted under the Non-Employee Directors' Deferred Compensation Plan, likewise tied one-for-one to common shares.

For these RSUs, the conversion into common stock and distribution are deferred until a specific date elected by the director or termination of service as a Corning director, as described in the footnotes. This structure means the director’s economic exposure to Corning equity is larger than the currently issued shares alone.
