GigCapital8 signs non-binding letter of intent to combine with Quantisimo
GigCapital8 Corp. entered a non-binding letter of intent with Quantisimo Corp., a special purpose vehicle created by WISeKey and SEALSQ, for a business combination. Under the letter, Quantisimo's existing equityholders would own a majority of the combined public company, and the pre-money enterprise value of Quantisimo is approximately $575 million. The deal is not binding and depends on definitive agreements, due diligence, shareholder approval, and financing, so it may not be completed.
Key points
- Pre-money enterprise value of Quantisimo: approximately $575 million, with a substantial rollover of equity expected from existing equityholders.
- Quantisimo's existing equityholders would own a majority of the combined company, which would be listed on a national stock exchange.
- The press release says the parties aim to reach $2 billion through up to five additional acquisitions and expect the transaction to close in the first quarter of 2027.
- Completion requires definitive documentation, shareholder approval, financing arrangements, and regulatory review; the filing states no assurance can be given.
