WISeKey International Holding Ltd to Hold Extraordinary General Meeting of Shareholders on April 27

WISeKey’s Board of Directors Recommends Shareholders Vote “FOR” All Proposals Submitted

Zug, Switzerland, April 4, 2023 – WISeKey International Holding Ltd (“WISeKey” or “Company”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity and IoT company, announced today that the Board of Directors has recommended to shareholders to vote “FOR” the proposals submitted to the Extraordinary General Meeting of Shareholders (“EGM“), which, as announced on March 30, 2023, will be held on April 27, 2023, 2pm CEST, at SIX ConventionPoint, Pfingstweidstrasse 110, 8005 Zurich, Switzerland.

As previously announced, the proposals primarily relate to the distribution to shareholders and holders of American Depositary Shares (ADSs) of 20% of the outstanding ordinary shares, par value USD 0.01 each (the SEALSQ Ordinary Shares), in SEALSQ Corp (SEALSQ). SEALSQ is a company organized and formed under the laws of the British Virgin Islands and a wholly-owned subsidiary of the Company. The distribution is to be made in the form of a special dividend in kind (the Special Dividend) out of the Company's capital contribution reserves booked in its statutory standalone financial statements as of December 31, 2021, based on a distribution ratio of (i) 0.002131728 SEALSQ Ordinary Share for each of the Company's registered share with a par value of CHF 0.01 each (the Class A Shares), (ii) 0.010658642 SEALSQ Ordinary Share for each of the Company's registered share with a par value of CHF 0.05 each (the Class B Shares), and (iii) 0.10658642 SEALSQ Ordinary Shares for each ADS, representing 10 Class B Shares each, each as outstanding as of the record date for the Special Dividend. The number of SEALSQ Ordinary Shares to be distributed to holders of Class B Shares, ADSs and Class A Shares may be adjusted, as further detailed in the EGM invitation. In lieu of fractional SEALSQ Ordinary Shares, shareholders and ADS holders will receive a cash payment consisting of the net cash proceeds from the sale of the fractional entitlements in the open market. The declaration and distribution of the Special Dividend are subject to the satisfaction or waiver (where permissible) of a number of conditions further detailed in the EGM invitation. If the distribution of the Special Dividend is approved by the shareholders at the EGM, and the related requirements are met, SEALSQ will be listed on the Global Market segment of the NASDAQ.

In order for the Special Dividend not to become subject to Swiss federal withholding tax of 35%, we have further proposed that capital contribution reserves be released to other general reserves from capital contribution (distributions out of which are not exempt from Swiss federal withholding tax) in an amount equal to the market value of the SEALSQ Ordinary Shares (after deduction of the book value of the Company's investment in SEALSQ). For further details regarding the Special Dividend, please refer to SEALSQ's U.S. registration statement on Form F-1, including a prospectus (the Prospectus), the EGM invitation and a Shareholder Information Brochure.

In addition to the two aforementioned proposals, we propose to amend our Articles of Association in order to, from time to time, be able to hold "virtual only" or “hybrid” general meetings. It will be ensured at these meetings that all shareholders’ rights are preserved as if shareholders were personally attending the meeting.

Instructions on how to participate and vote at the EGM can be found in the EGM invitation, which is being sent out this week to registered shareholders and will be published in the Swiss Official Gazette of Commerce on or about April 4, 2023.
