Wisekey International Holding S.A. insider activity reflects an amended report for Chief Innovation Officer Andreas Feuardent Moreira’s indirect holdings. His wife exercised 440 options under an Employee Stock Option Plan at an exercise price of $3.14 per option, disposing of the derivative securities and leaving no remaining options from this grant. This Form 4/A corrects an earlier filing that had mistakenly described the transaction as an acquisition of derivative securities rather than a disposition upon option exercise.
Wisekey International Holding S.A. insider Andreas Feuardent Moreira reported routine equity compensation activity involving Class B Shares held indirectly through his wife. On June 8, 2026, an employee stock option for 440 Class B Shares was exercised at an effective price of about $3.14 per share.
In connection with this exercise, 139 Class B Shares were disposed of as a tax-withholding payment at an effective price of about $10.51 per share, reflecting a tax-offset structure rather than an open-market sale. Following these transactions, 301 Class B Shares are reported as indirectly owned through his wife, and the related option position is fully exercised.
