Feuardent Moreira Andreas 4

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.
