Fendelet Quentin A. 4

What Happened

• Quentin Fendelet, Corporate Vice President and Chief Accounting Officer of Vicor (VICR), exercised 5,060 stock options on May 6, 2026 and immediately sold the 5,060 shares acquired.
• Exercises: 2,434 shares @ $50.00 (cost $121,700); 2,169 shares @ $41.61 (cost $90,252); 457 shares @ $60.61 (cost $27,699). Total exercise cost ≈ $239,651.
• Open-market sales (same day): total 5,060 shares sold in multiple trades for total proceeds ≈ $1,401,960 (weighted-average prices reported for each lot). This pattern is consistent with a cashless exercise (options exercised and shares promptly sold).

Key Details

• Transaction date: May 6, 2026; Form 4 filed May 8, 2026 (filed within the typical 2-business-day window).
• Exercised shares: 5,060 (three option lots at different strike prices). Sales: 5,060 shares in several open-market trades.
• Reported proceeds from sales: ≈ $1,401,960. Reported exercise cost: ≈ $239,651. Net proceeds (sales minus exercise cost) ≈ $1,162,309 (pre-tax).
• Post-transaction share ownership: not specified in the provided filing excerpt.
• Footnotes: reported sale prices are weighted averages; trades in the lots ranged roughly from $270.02 to $280.78 (see footnotes F1–F7 for exact sub-ranges).
• Derivative reporting: the filing shows the exercised option positions as disposed with $0 proceeds (standard for option-to-share conversion entries).

Context

• This is a routine option exercise with immediate sale of the acquired shares (a common way to cover exercise cost and tax withholding). It is a sale rather than an additional purchase (not a bullish purchase signal).
• The filing itself is factual; it does not explain motivation. For investors, purchases by insiders can be a stronger signal than routine exercise-and-sell transactions like this one.
