SEALSQ Increased Its Quantum Investment Fund to Over $35 Million and Provides Update on Strategic Quantum Technology Convergence

Geneva, Switzerland, July 07, 2025 (GLOBE NEWSWIRE) --

聽SEALSQ Corp (NASDAQ: LAES), a global leader in Post-Quantum and Quantum-resilient cybersecurity solutions, today announced its Quantum Investment Fund has been increased from $20 million to over $35 million. The increase is aimed at accelerating the convergence of Quantum, Post-Quantum cryptography, edge security, satellite communications, and secure identity infrastructure into a seamless and secure ecosystem for the next digital era.

Building a Quantum-Safe Technology Stack
SEALSQ鈥檚 Quantum fund is strategically deployed to ensure that its cybersecurity technology stack, from the edge to the cloud, and even into space, is fully Quantum-Resilient. The investments are carefully aligned to create a cohesive platform integrating:

• Quantum-Resistant Cryptography
• Custom-designed Quantum-Ready Semiconductors and TPM
• Secure Satellite Communication Infrastructure
• Blockchain-enabled Digital Identity Solutions
• AI-enhanced Hardware Security Modules (HSMs)
  
  

Strategic Investments executed so far and How They Interconnect

• Quantix Edge (Spain): SEALSQ, in conjunction with its parent company, WISeKey International Holding Ltd (鈥淲ISeKey鈥�) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company, has committed to invest approximately $12.0 million (鈧�10.2惭) to co-develop a Post-Quantum Semiconductor Center in Murcia, in collaboration with the Spanish government's SETT.ES program (鈧�20惭 support). This facility will design and manufacture Post-Quantum and Quantum-enhanced chips, forming the hardware foundation of SEALSQ鈥檚 secure ecosystem.
• WeCan Group (Switzerland): Through an approximately $3.5 million investment for a 28% stake, SEALSQ is integrating Post-Quantum digital identity and KYC capabilities into financial services. WeCan's blockchain-based solutions will interface securely with SEALSQ hardware using Quantum-resistant cryptographic keys.
• IC鈥橝lps (France): The approximately $14.7 million (鈧�10 million cash and 鈧�2.5 million stock, not including any potential earn-out consideration) acquisition of this ASIC design firm gives SEALSQ full control over custom silicon development, enabling Quantum-ready secure elements and chips that power everything from IoT devices to space-grade hardware. These ASICs are being optimized to run Post-Quantum algorithms such as CRYSTALS-Kyber.
• WISeSat.Space (Global): A $10 million investment is being used to deploy Post-Quantum-secured communication satellites. These satellites form part of the WISeSat.Space constellation, enabling encrypted communication between remote IoT nodes, financial networks, and critical infrastructure, even in areas without terrestrial connectivity.
• ColibriTD (France): A strategic initial investment of $100,000 stake in this Quantum cryptography startup ensures access to next-gen algorithms and protocols. ColibriTD is working on integrating Quantum Key Distribution (QKD) and hybrid PQC models into SEALSQ鈥檚 infrastructure, closing the loop from hardware to satellite to software.
  
  

Why Convergence Matters

The convergence of these technologies is not just an innovation strategy, it's a cybersecurity imperative. With the looming threat of Quantum computers breaking traditional encryption, SEALSQ is building a vertically integrated platform that ensures:

• Hardware and software are aligned to resist quantum attacks.
• Satellites and terrestrial systems communicate with Post-Quantum encryption.
• Identities and credentials are authenticated using PQC-enabled digital certificates.
• Data in motion, at rest, and in use is secured across borders and infrastructures.

鈥淭his isn鈥檛 a collection of siloed investments, it's a coordinated strategy to build the world鈥檚 first fully Post-Quantum secure digital ecosystem,鈥� said Carlos Moreira, CEO SEALSQ. 鈥淲e are preparing the critical infrastructure of tomorrow, today.鈥�

Backed by a strong cash balance of more than $120 million at June 30, 2025, SEALSQ is well-positioned to scale these investments and take a leadership role in helping governments, enterprises, and citizens transition to the Quantum era. As outlined in its recently announced growth strategy, SEALSQ expects this convergence to drive diversified revenues, strategic partnerships, and long-term shareholder value.

SEALSQ鈥檚 growth strategy for 2025 and beyond was announced in conjunction with the release of its H1 2025 preliminary unaudited revenue - .
