SEALSQ Updates on its Semiconductor Personalization Center Strategy

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced the continued expansion of its Semiconductor Personalization Center, a state-of-the-art facility dedicated to enabling secure, large-scale deployment of trusted chips and quantum-resistant devices for critical industries worldwide.

What the SEALSQ Personalization Center Does
At the heart of SEALSQ's strategy, the Semiconductor Personalization Center provides the secure environment where each chip is uniquely programmed, customized, and equipped with its own cryptographic identity. This process is designed to ensure that every device is authenticated, tamper-resistant, and ready to operate safely in today's digital ecosystems.

Key functions include:

• Key Injection & Secure Identity Provisioning
  Each chip is embedded with unique cryptographic keys and certificates, ensuring trusted digital identities and compliance with international Public Key Infrastructure (PKI) standards.
• Post-Quantum Security Integration
  Leveraging SEALSQ's cutting-edge R&D, the center can personalize chips with quantum resistant certificates and keys that to future-proof devices against emerging quantum computing threats.
• Customization at Scale
  The center can personalize chips for a wide range of sectors - including Smart Home, IoT, automotive, healthcare, industrial systems, aerospace, and defense, adapting security features and certificate types to industry-specific needs and standards. Typically for example, our certificates are compliant with the Matter protocol for Smart Homes, or WI-Sun for Smart Grid.
• Satellite & Space Applications
  Supporting SEALSQ's WISeSat.Space initiative, the center personalizes semiconductors used in satellite constellations, ensuring secure communications for space and ground infrastructure.
• Certified operations environment
  The Personalization Center operates under a Common Criteria Certified Environment (CCEAL5+) granting the highest security standards.
• Secure Supply Chain Management
  By controlling the chip personalization process, SEALSQ guarantees end-to-end traceability, protecting customers from counterfeit risks and ensuring regulatory compliance.

Global Expansion of Capabilities
Currently operating from Geneva (Switzerland) and Aix-en-Provence & Grenoble (France), the SEALSQ Semiconductor Personalization Center has plans to develop facilities across multiple locations including, but not limited to, Murcia (Spain), Arizona (USA), and Abu Dhabi (UAE), reinforcing the company's mission to provide sovereign, quantum-resistant security solutions to strategic markets across Europe, North America, and the Middle East.

Connected Through the Quantum Corridor
These centers are designed not to be isolated facilities but instead interconnected nodes within the Quantum Corridor - SEALSQ's secure global infrastructure designed to link personalization hubs with quantum-resistant key management, distributed PKI systems, and advanced cryptographic services.

The Quantum Corridor aims to ensure that:

• Every chip personalized in Europe, the USA, or the Middle East can securely interoperate.
• Quantum-ready identities are distributed across a resilient, geopolitically diverse infrastructure.
• Clients benefit from low-latency, sovereign, and scalable access to SEALSQ's personalization and security services.
  
  

"The SEALSQ Personalization Center is not just a manufacturing hub; it is the backbone of a trusted digital economy," said Carlos Moreira, CEO of SEALSQ. "By interconnecting our global sites through the Quantum Corridor, we ensure a continuous chain of trust that is both resilient to quantum threats and aligned with digital sovereignty requirements."
