BRUN LESLIE A 4

What Happened
Leslie A. Brun, a director of Corning Inc. (GLW), received an award of 1,806 restricted stock units (RSUs) on February 11, 2026. The RSUs were granted at $0.00 per share (coded as an award/derivative transaction) and represent contingent rights to receive Corning common stock in the future rather than an immediate cash or share purchase.

Key Details

• Transaction date: 2026-02-11; filing date: 2026-02-12. Transaction code: A (award/grant).
• Amount: 1,806 RSUs granted; reported price $0.00 (typical for RSU grants).
• Shares owned after transaction: not specified in the provided filing excerpt.
• Footnotes: F1/F3 — each RSU equals a contingent right to one share; F2 — conversion/distribution of the RSUs to common stock is deferred until a participant-elected date or termination of director service.
• Timeliness: Filing appears timely (filed the business day after the grant).

Context
RSU grants to directors are a common form of compensation (here noted as the annual equity retainer) and do not necessarily indicate the director is buying or selling stock. These RSUs are derivatives that convert to actual shares later under the plan’s vesting/deferred distribution rules, so they are not immediately dilutive shares in the insider’s hands.
