WISeKey International Holding Ltd plans to redomicile its corporate parent from Switzerland to the British Virgin Islands through a merger of WISeKey with its wholly owned BVI subsidiary, WISeKey International Corp., which would become the publicly traded parent of the group. A registration statement on Form F-4, including a preliminary prospectus for this merger, has been publicly filed with the U.S. SEC.
The merger is subject to multiple conditions, including approval by shareholders at an extraordinary general meeting expected on September 9, 2026, SEC effectiveness of the registration statement, required Nasdaq and SIX Swiss Exchange listing authorizations, and confirmation from the Swiss Takeover Board on maintaining the existing opting-out from mandatory takeover rules. Access to the merger agreement, related reports and audit confirmation, and financial statements for 2023–2025 for WISeKey and 2025 statements for WISeKey BVI will be provided at least 30 days before the meeting. Completion, timing, and anticipated benefits remain uncertain, and no offer or solicitation of securities is being made.
WISeKey International Holding Ltd announced that its wholly owned British Virgin Islands subsidiary, WISeKey International Corp. (WISeKey BVI), has filed a Form F-4 registration statement with the U.S. SEC to support a proposed redomiciliation of WISeKey from Switzerland to the British Virgin Islands via a merger. Under the proposal, WISeKey would merge into WISeKey BVI, which would remain as the publicly traded parent company and legal successor of the WISeKey group on Nasdaq and SIX Swiss Exchange.
The merger remains subject to several conditions, including WISeKey shareholder approval at an extraordinary general meeting currently expected on September 9, 2026, SEC effectiveness of the Form F-4, Nasdaq and SIX listing authorizations, and confirmation by the Swiss Takeover Board that WISeKey BVI benefits from the same opting-out from mandatory takeover provisions as WISeKey. Shareholders will receive access to detailed merger documentation and audited financial statements for 2025, 2024 and 2023, plus WISeKey BVI’s 2025 standalone financials, at least 30 days before the meeting. The registration statement is not yet effective and there is no assurance the merger will be completed on the anticipated timeline or at all.
