WISeKey Appoints Rolf Gobet to its Strategic Advisory Committee

Geneva – June 16, 2025 – WISeKey International Holding Ltd ("WISeKey") ((SIX: WIHN, NASDAQ:WKEY), a leading global cybersecurity, blockchain, and IoT company, today announced the appointment of Rolf Gobet to its Strategic Advisory Committee.

Mr. Gobet brings over three decades of experience in managing complex public-private projects, as he has held several leadership roles across Europe. As part of HP's EMEA e-government group, which focuses on providing technological solutions and services to public sector organizations in the Europe, Middle East, and Africa region, Mr. Gobet led the implementation of the world's first internet voting solution, an achievement made possible through a close collaboration with WISeKey. This initiative set a global benchmark for digital trust and innovation in democratic processes.

Mr. Gobet also played a key role in the development of TOSA, the world's first fully electric bus system that charges on the go without using overhead contact lines. This groundbreaking project was delivered through a public-private partnership involving major players, including multinational ABB, a global technology leader in electrification and automation, acquired by Hitachi in 2022. His ability to bring together stakeholders from government, industry, and academia has made him a recognized leader in technology-led transformation.

In French-speaking Switzerland, Mr. Gobet helped establish clusters of excellence, including the GAIN cluster, which unites aerospace companies in a collaborative innovation ecosystem. For more than 10 years, he directed the Office for the Promotion of Industries and Technologies (OPI), where he supported the economic development of companies ranging from startups to global enterprises. Mr. Gobet holds a master's degree from the University of Lausanne.

"We are honored to welcome Rolf to our Strategic Advisory Committee," said Carlos Moreira, Founder and CEO of WISeKey. "His pioneering achievements, deep public-private experience, and unique vision for sustainable and inclusive innovation make him a valuable asset to WISeKey's global mission."
