Zug, Switzerland, June 23, 2023 –WISeKey International Holding Ltd. (“WISeKey” or the “Company”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity and IoT company, announced today that its shareholders approved all items on the agenda of WISeKey's 2023 Annual General Meeting held on June 22, 2023.

Among other things, the shareholders re-elected Carlos Moreira, Peter Ward, Maria Pia Aqueveque Jabbaz, Cristina Dolan, David Fergusson, Jean-Philippe Ladisa and Eric Pellaton as members of the Board of Directors. Shareholders also re-elected Carlos Moreira as Chairman of the Board, and Cristina Dolan, David Fergusson and Eric Pellaton were re-elected as members of the Nomination and Compensation Committee.

In addition, the shareholders approved the Board of Directors' proposals to effect a 50 : 1 reverse stock split with respect to Class B Shares and a 25 : 1 reverse stock split with respect to the Class A Shares.
