CRILLY SEAN 4

What Happened
Sean Crilly, Corporate VP — Engineering, Power Systems at Vicor Corporation, was granted 373 derivative equity awards on May 5, 2026. The filing shows an acquisition price of $0.00 (no cash paid at grant). The award was granted under Vicor’s Amended and Restated 2000 Stock Option and Incentive Plan.

Key Details

• Transaction date and filing: grant dated 2026-05-05; Form 4 filed 2026-05-06 (appears timely).
• Grant size and price: 373 derivative awards at $0.00 per award.
• Vesting and expiration: awards vest over a five-year period (F1); options expire two years from each vesting date (F2).
• Shares owned after transaction: not specified in the provided excerpt.
• Nature of filing: classified as an award/grant of a derivative security (not an open-market purchase or sale).

Context
This was a compensation grant (derivative awards/options) rather than an open-market purchase or sale. Such grants give the right to acquire shares in the future if vesting conditions are met and do not represent an immediate cash investment by the insider. For retail investors, grants are routine executive compensation and should be viewed differently than insider purchases (which can be stronger bullish signals).
