GigCapital8 Corp. 8-K

What Happened
GigCapital8 Corp. (GIW) announced on June 25, 2026 (via a joint press release with WISeKey and SEALSQ) that it has entered a non‑binding letter of intent (LOI) to pursue a business combination with Quantisimo Corp., a special purpose vehicle formed by WISeKey International and its subsidiary SEALSQ. Quantisimo was created to build a "Trusted Quantum" platform using proprietary technologies, investments, IP and selected assets from the SealQuantum.com portfolio.

Key Details

• LOI date: June 25, 2026; joint press release filed as Exhibit 99.1 to the 8‑K.
• Quantisimo pre‑money enterprise value: approximately $575 million (per the LOI).
• Ownership: Quantisimo’s existing equityholders are expected to hold a majority of the surviving public company’s equity; substantial equity rollover is expected.
• Conditions: Transaction is non‑binding and subject to due diligence, negotiation of definitive agreements, shareholder and regulatory approvals, exchange listing approval, and financing.

Why It Matters
This LOI signals GigCapital8’s potential strategic shift toward the quantum-technology sector through a proposed business combination rather than an organic pivot. For investors, the deal could materially change GigCapital8’s business focus, ownership structure, and valuation if completed — but it is preliminary: no definitive agreement has been signed and the transaction depends on customary approvals, financing, and due diligence. The filing includes forward‑looking statements and cautions that the transaction may not be completed as described.
