ZUG, Switzerland - September 27, 2017 - WISeKey International Holding Ltd ("WISeKey" or the "Company") (SIX: WIHN), a provider of Cybersecurity and IoT solutions, today announced that its Board of Directors has approved an increase in its share capital out of authorized share capital on a non-preemptive basis through the issuance of up to 1,174,235 new Class B Shares to minority shareholders of WISeKey SA, a subsidiary of which the Company holds 90.9%, who have not tendered their WISeKey SA shares to the Company in the 2016 exchange offer but who have expressed an interest to do so now based on bilateral share exchange agreements. The Company intends to execute any such bilateral share exchanges on the basis of an exchange ratio of five (5) WISeKey SA shares for one (1) Class B Share. WISeKey expects execution of these bilateral transactions shortly, with a listing of the newly issued Class B Shares on the SIX Swiss Exchange to occur on or about September 29, 2017. In connection with such listing, WISeKey also intends to issue approximately 137,177 new Class B Shares to ExWorks in connection with an interest and term loan conversion pursuant to the terms of the previously announced acquisition line of credit agreement with ExWorks.

WISeKey has further been requested to release some Class A Shareholders from contractual transfer restrictions to enable such Class A Shareholders to enter into private transactions with Carlos Moreira regarding the exchange of their Class A Shares for Class B Shares held by Carlos Moreira. Subject to the execution of such private exchange transactions, the Company intends to consent to such release requests. Carlos Moreira will continue to be the Company's largest shareholder.
