Fendelet Quentin A., the Corporate VP and Chief Accounting Officer at Vicor Corporation (VICR), has been a consistent seller of company stock over the past year. Across 39 total Form 4 filings, all involving VICR, he has disposed of approximately $5.07 million in shares through open-market sales, with zero open-market purchases during the period. The selling has been steady and recent: in the last reported window alone, he executed 17 sell transactions, including a cluster of nine separate sales on May 11, 2026, totaling roughly $1.48 million, and five more on May 6, 2026, worth about $1.21 million. Earlier in the year, he sold $409,441 on March 2 and $355,440 on February 23.
The pattern is heavily weighted toward disposition, but the filings also reveal the mechanical nature of much of the activity. Interspersed with the sales are option exercises (coded "M")—such as the $168,543 exercise on May 11 and a $143,480 exercise on March 2—which typically generate shares that are then sold. A zero-value grant (coded "A") on May 5, 2026, also added to his holdings without a cash outlay. Notably, there are no purchases (coded "P") in the record, and no sales back to the issuer (coded "D"), meaning every disposition was an open-market transaction.
The dollar values of the individual sales range from modest—$29,500 on May 11—to substantial, including a $709,378 sale on May 6 and a $579,243 sale the same week. The concentration in a single ticker, combined with the absence of any buy-side activity, paints a clear directional picture: Fendelet has been monetizing his VICR equity consistently, with the most intense selling occurring in the first two weeks of May 2026. While the option exercises and grant explain the source of some shares, the sheer volume of open-market sales—over $5 million in roughly three months—signals a sustained reduction in his direct ownership stake.
