Key Terms

redomiciliation, cross-border merger, American Depositary Shares, primary listing

4 terms

redomiciliation regulatory

"redomiciliation ... from Switzerland to the British Virgin Islands"

Redomiciliation is when a company legally changes its country of incorporation while keeping the same business and assets, like moving a house to a new neighborhood but keeping the same furniture. Investors care because the company then follows a different set of laws and tax rules, which can change shareholder rights, reporting standards, dividend treatment and the ease of trading the stock, potentially affecting risk and return.

cross-border merger regulatory

"implemented through a cross-border merger"

A cross-border merger is when two companies based in different countries combine into a single business. Think of it as two households from different neighborhoods merging their kitchens: it can create access to new customers, technologies or cost savings, but also brings extra rules, taxes, currency swings and cultural differences that can affect profits and risk. Investors watch these deals closely because they can change a company’s growth prospects, costs and regulatory exposure.

American Depositary Shares financial

"existing American Depositary Shares of WISeKey"

American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.

primary listing financial

"where they will have a primary listing"

The primary listing is the main stock exchange where a company’s shares are officially registered and traded, and whose rules and regulators oversee its disclosures and corporate governance. For investors it matters because the primary listing determines the market’s trading hours and currency, the regulatory protections and reporting standards that apply, and where most trading volume and official filings are found—think of it as the stock’s legal “home address.”

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.
