LAESV SEALSQ Corporation

SEALSQ Corp (Nasdaq: LAES) (“SEALSQ” or “Company”), a leader in semiconductor, PKI, and Post-Quantum technology development, is pleased to announce the rebranding of its semiconductor manufacturing business from WISeKey Semiconductors S.A.S to SEALSQ France S.A.S (“SEALSQ France”). This strategic change is aimed at accelerating the development of state-of-the-art post-quantum semiconductor technologies in Meyreuil, located in the Aix-en-Provence, a prominent hub for semiconductor innovation in the South of France.

SEALSQ France stands at the forefront of the post-quantum era with its cutting-edge development center in Aix-en-Provence. The facility is dedicated to advancing a wide array of technologies including secure elements, roots of trust, cryptographic keys, and hardware security modules. This reinforces SEALSQ's commitment to driving technological progress and strengthening France's position in the global semiconductor market, safeguarding against potential geopolitical threats.

The engineering team in Meyreuil has successfully completed the design phase of the QUASARS post-quantum project. They are now commencing the production of the first engineering samples of post-quantum semiconductors, anticipated to be delivered by year end.

The QS7001™ RISC V quantum-resistant platform will form the foundation for SEALSQ’s upcoming products, the Post Quantum Secure Microcontroller and TPM known as VaultIQ™. The hardware of these chips will meet the stringent Common Criteria EAL5+ certification, while the firmware will incorporate CRYSTAL's post-quantum algorithms "Kyber" and "Dilithium," achieving NIST FIPS 140-3 certification.

In a strategic move to capitalize on the new chip's robust hardware capabilities, SEALSQ has initiated discussions with major electronics manufacturers to develop custom quantum-resistant chips that meet specific customer requirements. This step marks a significant advance in SEALSQ's commercial and industrial strategy, opening avenues for new business opportunities and revenue streams.

SEALSQ France, which currently employs in excess of 60 people, is planning to expand its workforce significantly in response to the expected demand for post-quantum semiconductors. This expansion will contribute to the local economy and further establish SEALSQ France as a key player in the global semiconductor industry.

Additionally, SEALSQ France is actively seeking funding under the European Chips Act (ECA), aligning with the European Union’s ambition to boost semiconductor production and market share within the region. This initiative underpins Europe's goal to reduce dependence on external supply chains and establish itself as a leader in the semiconductor industry by 2030.

SEALSQ France, located near Aix-en-Provence—the birthplace of the smart card and a continuation of our core activities—specializes in the design and customization of secure microcontrollers. These products act as digital passports to authenticate machines and high-value IoT devices, serving as a cornerstone for new US (US Cybertrust Mark) and European (ETSI XXX) standards now imposed on connected device manufacturers to protect users from cybercrime and industries from counterfeiting.

In an industry where only the number of companies globally who can design and market such products is highly restricted, SEALSQ France's expertise and track record of excellence allow us to serve high-profile clients.

Our core expertise lies in continually anticipating future cybercriminal threats, with quantum computing identified as the most significant emerging threat in our highly connected world. In response, SEALSQ France has developed a new generation of microcontrollers capable of withstanding quantum computing threats, aligning with recommendations from the National Agency for the Security of Information Systems (ANSSI).

Our ambitious project not only leads the way in research into semiconductor-based cybercrime prevention but also fosters job creation and utilizes academic resources, including a partnership with the MINES Saint-Etienne Research Institute. This initiative is integral to Europe and France's strategy to achieve sovereignty in the semiconductor supply chain, a critical component in the digital transformation of our world.

Carlos Moreira, CEO of SEALSQ, stated, "The strategic aspect of maintaining and developing post-quantum technology in France is particularly beneficial as it not only ensures that this key technology remains in France, thus strengthening our independence in the next-generation semiconductor sector, but it also stimulates investment cooperation between France and Switzerland. By increasing our investment in France, we are consolidating the foundations of a lasting technological and economic partnership that benefits the entire European ecosystem."

About SEALSQSEALSQ is at the forefront of technological innovation in digital security and semiconductor technology. With a focus on developing solutions that address the challenges of the post-quantum era, SEALSQ is committed to ensuring the security and integrity of digital interactions and transactions across various industries.

SEALSQ focuses on selling integrated solutions based on Semiconductors, PKI and Provisioning services, while developing Post-Quantum technology hardware and software products. Our solutions can be used in a variety of applications, from Multi-Factor Authentication tokens, Smart Energy, Smart Home Appliances, and IT Network Infrastructure, to Automotive, Industrial Automation and Control Systems.

Post-Quantum Cryptography (PQC) refers to cryptographic methods that are secure against an attack by a quantum computer. As quantum computers become more powerful, they may be able to break many of the cryptographic methods that are currently used to protect sensitive information, such as RSA and Elliptic Curve Cryptography (ECC). PQC aims to develop new cryptographic methods that are secure against quantum attacks.
