WISeKey Releases CEO Letter to Shareholders

Updates on the Listing of its Class B Shares in the U.S., on the NASDAQ, 
in the form of American Depositary Shares (ADSs)

Zug, Switzerland – WISeKey International Holding Ltd (“WISeKey”, SIX: WIHN), a leading cybersecurity and IoT company, today released a letter to shareholders from Carlos Moreira, WISeKey’s Founder and CEO. 

November 27, 2019

Dear Shareholders

            I am very pleased to update you on our previously announced intention to list our Class B Shares in the U.S., on The Nasdaq Stock Market LLC (“NASDAQ”), in the form of American Depositary Shares (ADSs).

            We have for that purpose filed with the U.S. Securities and Exchange Commission (SEC) a Registration Statement on Form 20-F.  The 20-F Registration Statement has been finalized and we will be requesting the acceleration of its effectiveness in the near future.  As a result, we expect to become an SEC reporting company in early December, qualifying as a foreign private issuer, in the U.S. and we will, in addition to the disclosures, filings and public releases required under Swiss law and the rules and regulations of the SIX Swiss Exchange, be required to file disclosure statements with the SEC and make public disclosures under the U.S. securities laws.  A copy of the 20-F Registration Statement may be obtained from the SEC website at

            We are also working on the listing process with NASDAQ, which we hope to conclude shortly.  Upon conclusion of the NASDAQ listing process and upon effectiveness of the 20-F Registration Statement, our Class B Shares will be listed for trading in the form of ADSs on NASDAQ; our Class B Shares in their current form will continue to be listed and traded on the SIX Swiss Exchange.  

If you wish to hold shares that are eligible for trading in the U.S., you will need to convert your Class B Shares into ADSs.  The Bank of New York Mellon is the Depositary Bank for our ADSs.  Attached is for your reference a description of the ADS conversion process.  Please note that Class B Shares that are subject to resale limitations in the U.S. may not be converted into ADSs absent an exemption from the U.S securities registration requirements.     

Should you have any questions about the conversion of our Class B Shares into ADSs please do not hesitate to contact: Nathalie Verjus at or Dourgam Kummer at
