Launch of Tax Solicitation Process for WISeKey Class B Shareholders
"This dividend distribution is a complex process across multiple geographies, thus I would strongly encourage our Class B Shareholders to pay close attention to the instructions included in the letters or e-mails they will receive in order to ensure they receive the full amount of the dividend to which they are entitled," said Carlos Moreira, Founder and CEO of WISeKey.

As the dividend-in-kind distribution is considered a taxable event under US Tax Law, the Company has launched a website where shareholders holding WISeKey Class B Ordinary Shares can complete the necessary information to ensure that the correct tax withholding treatment is applied to the dividend-in kind. To receive the declared dividend distribution without the application of withholding taxes, WISeKey Class B Ordinary Shareholders are required to complete a Tax Certification. To review related documentation and complete the tax certification related to WISeKey International Holding AG., shareholders are invited to visit the following website: www.ComputershareCAS.com/WiseKey or https://wisekey.computersharecas.com.
