The company also advanced post-quantum security, with its QS7001 Post-Quantum Secure Element obtaining NIST SP 800-90B Entropy Source Validation and completing key Common Criteria security tests. Through its SEALQuantum Fund, SEALSQ targets a $200 million internal allocation and has already committed over $60 million to strategic technology investments.
SEALSQ Corp filed a Form 6-K highlighting that Quantisimo Corp, its quantum-focused special purpose vehicle jointly created with WISeKey, has signed a non-binding Letter of Intent with SPAC GigCapital8 to pursue a Nasdaq listing. The contemplated business combination implies an expected pre-money enterprise value of about $575 million, with an ambition to reach $2 billion through additional acquisitions of up to five quantum companies. Closing is currently targeted for the first quarter of 2027 and would remain subject to definitive agreements, shareholder and regulatory approvals, financing, and other customary conditions, with no assurance the transaction will be completed.
SEALSQ Corp, through its joint venture Quantisimo, entered into a non-binding letter of intent for a business combination with SPAC GigCapital8. The contemplated deal would create a publicly traded platform focused on trusted quantum infrastructure, with the combined company expected to have a pre-money enterprise value of about $575 million.
The parties envision growing this platform via consolidated acquisitions of up to five additional quantum companies, and the transaction is currently expected to close in the first quarter of 2027. SEALSQ is expected to contribute selected quantum-focused assets, technologies, and intellectual property to Quantisimo, but the transaction is subject to due diligence, definitive agreements, regulatory and shareholder approvals, financing, and other closing conditions, and may not be completed.
