Geneva, Switzerland, October 24 2025 -- SEALSQ Corp ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced that its ordinary shares have been approved for trading on the NASDAQ Global Select Market, effective October 27, 2025. The uplisting from the NASDAQ Capital Market reflects SEALSQ’s continued development, operational progress, and adherence to the highest financial and governance standards required by NASDAQ.

The NASDAQ Global Select Market is the highest tier of the NASDAQ Stock Market, reserved for companies that meet the most stringent financial and liquidity standards. SEALSQ’s inclusion in this tier aligns with its vision to expand its presence among institutional investors and global partners.

In addition, SEALSQ’s market capitalization has recently surpassed $1 billion, and has subsequently remained above this threshold, marking another significant milestone for the Company and underscoring increasing investor confidence in its strategic direction and technology leadership.

“Being uplisted to the NASDAQ Global Select Market represents an important validation of SEALSQ’s progress and market credibility,” said Carlos Moreira, CEO of SEALSQ. “This achievement, along with reaching the $1 billion market capitalization milestone, demonstrates growing recognition of SEALSQ’s role as a trusted enabler of digital trust and security in an increasingly connected and post-quantum world. From secure elements to our PKI and upcoming post-quantum implementations, customers are choosing SEALSQ to safeguard identities, devices, and data across critical industries.”

Strategic Momentum

SEALSQ continues to advance its product portfolio focused on semiconductors, secure hardware, and post-quantum-ready technologies, serving customers in the IoT, automotive, industrial, and defense sectors. Key initiatives include:

• Scaling secure silicon for identity, access, and embedded security across IoT, healthcare, industrial, and government deployments.
• Post-quantum leadership with implementations designed to help customers transition to quantum-resistant cryptography.
• Global partnerships that expand distribution and solution integration across Europe, the Middle East, and the Americas.
• Post-Quantum Corridor project and “Made in USA” initiative, reinforcing SEALSQ’s commitment to trusted manufacturing, research collaboration, and digital sovereignty.
• SEALSQ, among fewer than ten companies worldwide certified to Common Criteria EAL5+ and FIPS 140-3 standards, operates secure personalization centers in Switzerland and France, with planned expansions at various stages of development in Spain, India, the Middle East and the United States. As part of its U.S. strategy, SEALSQ is evaluating California and Arizona as potential locations for its new Post-Quantum Personalization Center, dedicated to secure chip provisioning for defense, IoT, and space applications.

Robust Financial Position

SEALSQ enters this new growth phase with a strong cash position of almost $450 million as of today, ensuring the Company has the financial resources to execute its ambitious roadmap, including investments in new semiconductor manufacturing, R&D, Sales & Marketing, and strategic acquisitions in the post-quantum and IoT security sectors.

This liquidity reinforces SEALSQ’s ability to scale production, expand its footprint in the USA, and accelerate global adoption of its post-quantum technologies while maintaining long-term financial stability.

Accelerating Post-Quantum Innovation Through its “Made in USA” Initiative

In alignment with U.S. and global cybersecurity priorities, SEALSQ has launched a “Made in USA” strategy featuring plans to develop and deploy post-quantum cryptographic (PQC) chips domestically.

This initiative aims to support the future development of:

• Semiconductor innovation in the US: Establishing new personalization, assembly, and testing lines dedicated to PQC semiconductors.
• Quantum-resilient supply chains: Ensuring critical infrastructure and government customers benefit from locally produced, NIST-compliant PQC devices.
• Collaborations with U.S. institutions and defense programs: Reinforcing national and digital sovereignty through strategic partnerships.
  
  Through this strategic move, SEALSQ strengthens its leadership in quantum-safe security while fostering the creation of trusted, end-to-end ecosystems for sensitive data protection.

Introducing the Post-Quantum Corridor

To further accelerate post-quantum innovation, SEALSQ intends to establish the Post-Quantum Corridor (PQC), a cross-border technology and industrial initiative linking the United States, Switzerland, and the rest of Europe featuring:

• A secure technology bridge connecting U.S. semiconductor innovation with European cryptographic research and manufacturing expertise.
• A collaborative ecosystem bringing together universities, R&D centers, and government agencies to develop interoperable post-quantum standards and products.
• A supply chain accelerator ensuring a reliable transition to quantum-safe hardware and software solutions worldwide.

This corridor is planned to become a foundational element of SEALSQ’s long-term vision: establishing a globally distributed, quantum-secure infrastructure that safeguards data integrity, privacy, and resilience for generations to come.
