Exhibit 1.1

WISeKey to Split its ADS on July 5, 2023

Geneva, Switzerland, June 21, 2023 – WISeKey International Holding Ltd. (NASDAQ: WKEY / SIX: WIHN) (“WISeKey” or the “Company” or the “Group”), a leading cybersecurity and IoT company, announced today a 1-for-2.5 reverse split of American Depository Shares (“ADS”) listed on the NASDAQ under the ticker “WKEY” (the “ADS Reverse Split”).

Under the current ratio, 1 ADS represents 10 Class B shares listed on the SIX Swiss Exchange.

For its 2023 Annual General Meeting of Shareholders to be held on June 22, 2023, the Board of Directors’ proposals for shareholder approval include a reserve stock split of the Company’s Class B shares at a ratio of 50:1 (the “Reverse Stock Split”). The number of Class B shares issued and outstanding of the Company will, relative to the number of Class B Shares issued and outstanding immediately prior to the effectiveness of the Reverse Stock Split, decrease proportionally.

Should the Company’s shareholders approve the Reverse Stock Split, WISeKey will then carry out a 1-for-2.5 ADS Reverse Split, which means that, post-Reverse Stock Split and ADS Reverse Split, 2 ADSs will represent 1 Class B share.

The ADS holders of record on the effective date of the ADS Reverse Split will not be required to take any action in connection with the ADS ratio change. The exchange of two and a half (2.5) new for every one (1) then-held ADS will occur automatically with the then-held ADSs being canceled and new ADSs being issued by the depositary bank, in each case as of the effective date for the ADS ratio change. WISeKey’s ADSs will continue to trade on the NASDAQ under the symbol “WKEY”.

The number of shares owned by ADS holders will be adjusted on Wednesday, July 5, 2023.

After the Reverse Stock Split and as a result of the ADS Reverse Split, the ADS price is expected to increase proportionally, but the Company can give no assurance that the ADS price after the change in the ADS ratio will be equal to or greater than 2.5 times ADS price before the change.
