Wisekey (WKEY) CIO Andreas Feuardent Exercises Options

What Happened

Andreas Feuardent, Chief Innovation Officer of Wisekey International Holding S.A. (WKEY), exercised options on June 8, 2026. The filing shows two derivative exercises: 440 shares exercised at an exercise price of $3.14 (total paid $1,382) and a second 440-share derivative recorded with a $0 exercise price. To cover tax withholding, 139 shares were surrendered (disposed) at $10.51 per share (value approx. $1,461). After withholding, the reporting person netted 741 shares (880 exercised minus 139 withheld).

Key Details

Transaction date: June 8, 2026; Form 4 filed June 16, 2026 (filed after the transaction date).
Exercise details: 440 shares @ $3.14 (≈ $1,382); 440 shares @ $0 (derivative instrument).
Tax withholding: 139 shares withheld/disposed @ $10.51 (≈ $1,461).
Net new shares received: 741 shares.
Footnotes: Exchange rates used to convert CHF exercise prices to USD (rate 0.7955 CHF per USD reported June 5, 2026). A tax-offset right was granted with the option, entitling the holder to a cash payment equal to the tax withholding on exercise (including withholding on the tax-offset payment).
Shares owned after transaction: Not provided in the supplied filing.
Timeliness: The Form 4 was filed eight days after the June 8 transactions (appears late relative to the usual 2-business-day deadline).

Context

This was an options exercise (derivative conversion). Part of the issuance was surrendered to satisfy tax withholding — a routine administrative step, not an open-market sale of additional shares for cash.
Because the filing shows a net acquisition of 741 shares, this is a net purchase-like event for the insider. However, filing delay may affect prompt market transparency.
