What Happened

Stefan Becker, SVP, Finance & Corporate Controller at Corning (GLW), was granted 4,846 restricted stock units (RSUs) on April 1, 2026. The Form 4 reports the award as a derivative acquisition at $0.00 per unit (code A). RSUs are a compensation award (not an open-market purchase or sale).

Key Details

Transaction date: 2026-04-01; Grant type: RSU award (derivative); Reported price: $0.00 per unit.
Shares/units acquired: 4,846 RSUs. Total cash paid at grant: $0 (award).
Shares owned after transaction: Not specified in the provided filing excerpt.
Footnotes: F1 notes each RSU equals a contingent right to one share. Other footnotes indicate vesting schedules across multiple tranches (100% vesting on 4/15/2026; 4/15/2027; 4/14/2028; and 4/16/2029) and that events like retirement, death, or disability may accelerate vesting.
Filing timeliness: Report filed 2026-04-02 for a 2026-04-01 transaction; appears to be filed timely.

Context

RSUs are compensation awards that convert to shares only upon vesting; they do not represent immediate stock purchases or sales. This grant increases Becker’s potential future stake if the RSUs vest, but it is a routine executive compensation action rather than an indicator of a personal market purchase.
