SEALSQ Announces Deal With Quantix Edge Security to Develop Spain’s First Post-Quantum Semiconductor Personalization Center Worth $25M in Expected Revenue

Geneva, Switzerland, Sept. 26, 2025 (GLOBE NEWSWIRE) —

The Spanish Government recently announced a €19.6 million public investment in Quantix, which is projected to generate €793 million of economic impact in the Region of Murcia over the next five years https://digital.gob.es/comunicacion/notas-prensa/secretaria-digitalizacion-e-inteligencia-artificial/2025/09/2025-09-25

SEALSQ Corp (NASDAQ: LAES) (“SEALSQ” or “the Company”), a leader in semiconductors, PKI, and post-quantum technology hardware and software, today announced a definitive agreement with Quantix Edge Security to develop and deploy Spain’s first post-quantum semiconductor personalization center in the Region of Murcia.

This agreement, a key milestone in the Quantix Edge Security project previously announced by the Company in June 2024, is expected to generate $25 million of revenue over the next three years with recognition likely to be milestone based over the course of the project. The Company anticipates that the project will start in H1 2026 and further expects that the project milestones will occur regularly over the life of the project creating a relatively even spread of revenue recognition..

This development is aligned with the Spanish Government’s national strategy to strengthen sovereignty in critical sectors such as semiconductors and cybersecurity. In September 2025, the Government announced a €19.6 million public investment in Quantix, projected to deliver €793 million in economic impact to the Region of Murcia over the next five years. The new center will reinforce Spain’s role as a European hub for post-quantum and cybersecurity-focused semiconductor innovation.

SEALSQ also plans to accelerate commercialization by distributing its post-quantum semiconductors through Quantix Edge Security beginning in 2026, even while the Murcia facility remains under construction. This strategy will enable early adoption of SEALSQ’s quantum-resistant technologies and supports the Company’s $170 million pipeline of potential revenue as part of its broader Quantum Roadmap.

In parallel, SEALSQ is preparing to launch the Quantum Shield “QS7001” in mid-November 2025, the world’s first¹ secure chip to embed NIST-standardized quantum-resistant algorithms ML-KEM (CRYSTALS-Kyber) and ML-DSA (CRYSTALS-Dilithium) at the hardware level. The QS7001 will provide robust protection for critical applications including cryptocurrency and blockchain infrastructures, defense and aerospace systems, healthcare platforms, and Internet of Things (IoT) ecosystems.

The QS7001 delivers secure key storage, post-quantum signing, and hybrid migration frameworks that enable seamless transitions from RSA/ECC to quantum-safe cryptography, along with an open hardware platform that supports personalized firmware. The product also paves the way for SEALSQ’s upcoming QVault TPM, a Trusted Platform Module scheduled for release in the first half of 2026.
