WISeKey’s Redomiciliation from Switzerland to the British Virgin Islands Becomes Legally Effective
Zug, Switzerland, October 1, 2026 – WISeQey Corp. (formerly known as WISeKey International Corp., “WISeQey” or the “Company”) (SIX: WIHN; NASDAQ: WKEY), a leading global quantum cybersecurity and space IoT company, today announced that the previously announced redomiciliation of WISeKey International Holding Ltd (“WISeKey”) from Switzerland to the British Virgin Islands became legally effective today (the “Redomiciliation”). The Redomiciliation was implemented through a cross-border merger of WISeKey with and into WISeQey, its wholly owned British Virgin Islands subsidiary, with WISeQey as the surviving company (the “Merger”).
The existing American Depositary Shares of WISeKey will continue to trade on Nasdaq, and the existing Class B shares of WISeKey will continue to trade on the SIX Swiss Exchange, in each case through the close of business on Friday, October 2, 2026. The ordinary shares of WISeQey are expected to commence trading under the ticker symbol “WQEY” on both the Nasdaq Global Market and the SIX Swiss Exchange (where they will have a primary listing) at market open on Monday, October 5, 2026.
Following cancellation of the existing WISeKey equity securities, holders of WISeKey equity securities will receive the applicable equity securities of WISeQey in accordance with the exchange ratios, elections, and settlement procedures previously communicated to shareholders and described in the prospectus relating to the Merger.
In connection with the completion of the Redomiciliation, (i) each WISeKey ADS will be exchanged for one-half of one WISeQey ordinary share, (ii) each WISeKey Class B share will be exchanged for one WISeQey ordinary share (unless such holder elected to receive WISeQey Class B shares), and (iii) each WISeKey Class B share held by a holder that elected to receive unlisted WISeQey Class B shares will be exchanged for ten WISeQey Class B shares.
