Vicor (VICR) VP Philip D. Davies Exercises Options & Sells 5,419 Shares
What Happened
- Philip D. Davies, VP Global Sales & Marketing and a company director at Vicor (VICR), exercised three option tranches totaling 5,419 shares (1,920 @ $41.61; 2,585 @ $60.61; 914 @ $75.43) on 2026-03-05, paying roughly $305,511 in aggregate strike cost.
- He then sold the 5,419 shares in multiple open-market transactions that same day for total proceeds of about $1,027,829. This sequence (exercise followed by sale) is effectively a cashing-out of option gains rather than a new purchase.
Key Details
- Transaction date: 2026-03-05; Form 4 filed 2026-03-09 (timely filed).
- Options exercised: 5,419 shares in three tranches (strike prices $41.61, $60.61, $75.43); aggregated exercise cost ≈ $305,511.
- Open-market sales: 5,419 shares across many trades at prices ranging roughly from $177.18 to $202.26; proceeds ≈ $1,027,829. Several reported prices are weighted averages of multiple trades (see filing footnotes).
- Notable footnotes: at least one sale was made pursuant to a Rule 10b5-1 trading plan adopted Nov 21, 2025; options have a two-year expiration from each vesting date (per filing).
- Shares owned after the transaction are not specified in the provided data.
Context
- This was an option exercise followed by immediate sales (common “exercise-and-sell” / cashless-like outcome): the insider realized the difference between market price and strike prices.
- Sales executed under a 10b5-1 plan are pre-arranged trading programs that can indicate trades were planned in advance, not necessarily a contemporaneous signal about the insider’s view.
- The filing is factual and timely; it documents routine monetization of vested equity rather than an additional purchase (which retail investors often view as a stronger bullish signal).
