WISeKey Announces Public Filing of Registration Statement Relating to Proposed Spin-off of its Semiconductor Business

Geneva, Switzerland, February 13, 2023 – Ad-Hoc announcement pursuant to Art. 53 of SIX Listing Rules– WISeKey International Holding Ltd (NASDAQ: WKEY / SIX: WIHN) (“WISeKey” or the “Company”), a leading Swiss cybersecurity, AI and IoT company announced today that, through a wholly-owned subsidiary, SEALSQ Corp, it has publicly filed a registration statement on Form F-1 pursuant to the Securities Act of 1933 with the U.S. Securities and Exchange Commission ( “SEC”) to effect a partial spin-off of SEALSQ Corp (“SEALSQ”), currently a wholly-owned subsidiary that acts as the holding company for our semiconductor business. SEALSQ is in the process of applying to have its Ordinary Shares listed on the Nasdaq Global Market under the ticker symbol “LAES”.

WISeKey proposes to distribute 20% of SEALSQ’s outstanding Ordinary Shares, to holders of WISeKey Class B Shares, including holders of WISeKey ADSs, and to holders of WISeKey Class A Shares, in each case as a partial spin-off distribution as a dividend in kind to such holders. WISeKey will initially retain 100% ownership of SEALSQ’s Class F Shares. The transaction is expected to be completed around the beginning of the second quarter of 2023, and remains subject to the applicable approvals and conditions to the transaction being satisfied or waived, including but not limited to, the Form F-1 being declared effective by the SEC, the approval of the listing of SEALSQ’s Ordinary Shares on the Nasdaq Global Market and the approval of the spin-off distribution by the WISeKey shareholders at an Extraordinary General Meeting. There can be no assurance that the transaction will occur, or if one does, its terms or timing.

SEALSQ is dedicated to advancing the field of post-quantum computing, making it accessible to a wide range of industries that are already using our semiconductors, and it is enabling advances in communications, computing, healthcare, military systems, transportation, clean energy, and countless other applications.

The WISeKey board of directors believes that a partial spin-off of its global semiconductor business presents a significant market opportunity to investors in light of both the current market and increased cybersecurity regulation.

A registration statement relating to these securities has been filed with the SEC but has not yet become effective. These securities may not be sold, nor may offers to buy be accepted, prior to the time the registration statement becomes effective. This announcement does not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
