Key Details

  • Transaction date: 2026-03-31; Filing date: 2026-04-01 (timely filing).
  • Grant: 257 RSUs at $135.97 per unit; total value $34,944.
  • Shares owned after transaction: not disclosed in this Form 4.
  • Footnotes: RSUs represent contingent rights to receive one share each (F1, F3, F4). Conversion/distribution of RSUs is deferred until a date elected by the participant or upon termination of service under the Non-Employee Directors' Deferred Compensation Plan (F2, F5). The award appears to be the annual equity retainer for non-employee directors.

Context RSU grants to non-employee directors are a routine form of compensation and do not represent an immediate purchase or sale of shares. These RSUs are derivative awards that will convert to common stock at a later date per the director deferred compensation plan; they do not imply an immediate market view by the director.
