SEALSQ Corp. (LAES) shares rebounded before Thursday’s opening as Quantisimo advanced plans for a $575 million Nasdaq transaction. LAES gained 2.61% to $3.3195 in pre-market trading after closing 3.29% lower at $3.2300. The proposed deal would create a listed platform focused on quantum technology and post-quantum security.
SEALSQ Corp, LAES
SEALSQ and parent company WISeKey jointly established Quantisimo as a special purpose vehicle. Quantisimo has now signed a non-binding letter of intent with GigCapital8 Corp. Both companies will explore a business combination that could list Quantisimo on Nasdaq.
The proposed company would carry an initial pre-money enterprise value of about $575 million. However, Quantisimo plans to expand through acquisitions involving as many as five additional quantum companies. The parties currently target the first quarter of 2027 for completing the transaction.
Quantisimo Plans Broader Quantum Technology Platform
Quantisimo aims to build a public company focused on trusted infrastructure across the quantum technology sector. The platform will combine internal technologies, intellectual property, investments, partnerships, and selected business assets. It will also target commercial and military uses across computing, communications, security, and artificial intelligence.
The company plans to source selected assets and strategic interests from SEALSQ’s SealQuantum.com portfolio. These assets may include technologies, investments, intellectual property, and projects operating across several quantum markets. SEALSQ must still receive final board approval before contributing the selected assets.
WISeKey will support the platform through its experience in cybersecurity, digital trust, and secure digital ecosystems. Meanwhile, SEALSQ will provide semiconductor expertise, cryptographic systems, and quantum-resistant security technologies. Together, the companies aim to create an integrated platform serving the expanding quantum economy.
Deal Requires Agreements, Approvals and Financing
GigCapital8 operates as a publicly traded special purpose acquisition company under the GigCapital Global franchise. The company has focused its latest acquisition strategy on aerospace, defense, and advanced quantum technology businesses. Its planned combination with Quantisimo would provide a public structure for consolidating several quantum companies.
The parties will begin detailed due diligence and work toward definitive agreements during the coming months. They must also secure regulatory clearances, shareholder approvals, financing arrangements, and other standard closing requirements. The non-binding letter does not guarantee that either party will complete the proposed transaction.
The announcement follows increased United States support for quantum computing, sensing, networking, workforce development, and secure supply chains. Quantisimo expects these policies to strengthen demand for quantum applications and post-quantum security systems. The planned platform would position SEALSQ and WISeKey within that expanding technology and cybersecurity market.
