WISeKey International Holding Ltd reports that shareholders approved all agenda items at the company’s 2026 Annual General Meeting held on June 29, 2026. All proposals submitted by the Board of Directors received support, reflecting broad backing for current strategy and leadership.
The company highlights progress across its cybersecurity, digital identity, IoT, space, NFT, and DePIN-focused subsidiaries, noting that more than 1.6 billion of its microchips are deployed in IoT sectors. Management reiterates its focus on executing strategy, pursuing new growth opportunities, and building long-term value.
WISeKey International Holding Ltd. has furnished a Form 6-K highlighting a strategic move in quantum technologies. WISeKey and its subsidiary SEALSQ Corp. have created a special purpose vehicle, Quantisimo Corp., which has signed a non-binding Letter of Intent with GigCapital8 Corp., a Nasdaq-listed SPAC, for a potential business combination. The combined company is expected to have a pre-money enterprise value of approximately $575 million, with a stated ambition to build a consolidated US$2 billion “Trusted Quantum Pure-Play” platform through additional acquisitions of up to five quantum companies. The transaction is currently expected to close in the first quarter of 2027, but remains subject to due diligence, definitive agreements, regulatory and shareholder approvals, financing, and other customary conditions, with no assurance that it will be completed.
WISeKey International Holding Ltd has signed a merger agreement to move its legal home from Switzerland to the British Virgin Islands through a merger with its wholly owned subsidiary, WISeKey International Corp. in the BVI. WISeKey would merge into WISeKey BVI, which would become the new listed parent company on both Nasdaq and SIX Swiss Exchange.
Each existing WISeKey share class will be exchanged for the corresponding WISeKey BVI share class, and the current ADS program will be terminated, with ADS holders receiving WISeKey BVI ordinary shares. Holders of WISeKey Class B shares will have election rights among different WISeKey BVI share classes, or receive ordinary shares if they do not elect. The transaction requires shareholder approval at an extraordinary general meeting expected in Q3 2026 and is subject to an effective Form F-4 registration statement, listing approvals, Swiss Takeover Board confirmation, and other Swiss and BVI legal and regulatory conditions.
WISeKey International Holding Ltd reports that WISeSat.Space Holdings Corp. (“Pubco”), a wholly owned subsidiary of WISeSat.Space Corp., has filed a registration statement on Form F-4 with the SEC for a previously announced business combination with Columbus Acquisition Corp. (“CAC”). The deal is governed by a Business Combination Agreement dated November 9, 2025. Completion of the transaction requires the Form F-4 to be declared effective, approval of CAC shareholders, and Nasdaq approval to list Pubco’s registered shares. If completed, both WISeSat and CAC will become subsidiaries of Pubco, and the combined company is expected to trade on Nasdaq under the ticker symbol “SAIQ”.
Wisekey International Holding S.A. insider activity reflects an amended report for Chief Innovation Officer Andreas Feuardent Moreira’s indirect holdings. His wife exercised 440 options under an Employee Stock Option Plan at an exercise price of $3.14 per option, disposing of the derivative securities and leaving no remaining options from this grant. This Form 4/A corrects an earlier filing that had mistakenly described the transaction as an acquisition of derivative securities rather than a disposition upon option exercise.
Wisekey International Holding S.A. insider Andreas Feuardent Moreira reported routine equity compensation activity involving Class B Shares held indirectly through his wife. On June 8, 2026, an employee stock option for 440 Class B Shares was exercised at an effective price of about $3.14 per share.
In connection with this exercise, 139 Class B Shares were disposed of as a tax-withholding payment at an effective price of about $10.51 per share, reflecting a tax-offset structure rather than an open-market sale. Following these transactions, 301 Class B Shares are reported as indirectly owned through his wife, and the related option position is fully exercised.
WISeKey International Holding reported that its subsidiary SEALCOIN secured a $4 million strategic investment commitment to advance a space-based blockchain transaction layer for machines and satellites. The funding includes $1 million from The Hashgraph Group and $3 million from WISeKey.
The capital is intended to support development of the QAIT-powered SEALCOIN ecosystem, integrating WISeSat satellites, secure semiconductor technology and decentralized identity infrastructure. SEALCOIN recently completed its SPACEDROP campaign, where more than 45,000 participants interacted with 19 operational WISeSat satellites to validate satellite-to-blockchain communications.
WISeKey International Holding AG reports that its subsidiary SEALSQ Corp has entered into and closed a Series A Investment Agreement to acquire a minority interest in French quantum computing company Quobly SAS. SEALSQ subscribed for Series A preferred shares with attached broad-based anti-dilution ratchet warrants for an aggregate investment of EUR 14,999,400, subject to conditions precedent that have now been satisfied.
The ratchet warrants adjust SEALSQ’s subscription price if Quobly issues additional shares over the next four years at a lower price than the Series A price. As part of the deal, SEALSQ gained the right to appoint one member to Quobly’s supervisory board and named its CEO, Carlos Moreira, to that seat. Any two investor-appointed board members may veto certain major Quobly decisions, such as bylaws changes, mergers, major reorganizations, or new securities issuances.
An accompanying press release notes that SEALSQ participated as a lead investor in Quobly’s €115 million Series A round via the SEALSQ Quantum Fund, positioning the investment as a key step in SEALSQ’s quantum security and infrastructure strategy.
WISeKey International Holding Ltd reports that its WISeSat subsidiary has confidentially submitted an amended draft registration statement on Form F-4 to the SEC on May 29, 2026. This filing supports a previously announced proposed business combination among WISeSat, Columbus Acquisition Corp, Pubco and related entities.
Upon completion of the transaction, WISeSat and Columbus Acquisition Corp are expected to become subsidiaries of Pubco, with the combined company anticipated to trade on Nasdaq under the ticker “WSAT,” subject to regulatory effectiveness, Nasdaq listing approval and Columbus Acquisition Corp shareholder approval.
WISeKey International Holding’s Form 6-K highlights two SEALSQ Corp transactions that expand its post-quantum and financial-compliance capabilities. SEALSQ has acquired a majority stake in Swiss fintech Wecan Group and agreed to invest CHF 5 million to speed development of an AI-powered, post-quantum compliance “copilot” for global financial institutions.
SEALSQ also acquired 100% of Miraex SA, a Swiss photonics company whose Thin Film Lithium Tantalate photonic integrated circuits form a quantum interconnect layer between processors and communication networks. Both deals are funded through SEALSQ’s internal Quantum Fund, which has $200 million of approved capital and has deployed over $65 million to build a vertically integrated “Quantum Sovereign Stack.”
