The definitive business combination agreement provides a clear path for WISeQey and SEALSQ to monetize their stake in Quantisimo via a Nasdaq-listed public company. The transaction is subject to shareholder approval and regulatory clearances; monitor the filing of the F-4 registration statement and the SPAC shareholder vote for key milestones. The $15 million minimum cash condition and the sponsor's commitment not to redeem shares reduce execution risk.
