SEALSQ, WISeKey and Canton of Jura Sign MoU to Establish a Swiss Post-Quantum Semiconductor and Cybersecurity Center

DELÉMONT, Switzerland, Sept. 21, 2026 (GLOBE NEWSWIRE) --

Proposed CHF 40-60 million public-private initiative aims to establish sovereign semiconductor personalization capabilities in Switzerland and create up to 250+ direct jobs in the Canton of Jura

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, its parent company, WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY), (“WISeKey” or “the Company”) a global leader in cybersecurity, digital identity and IoT, and The Republic and Canton of Jura, Switzerland, today announced the signing of a Memorandum of Understanding (“MoU”) to collaborate on the establishment of a Post-Quantum Semiconductor and Cybersecurity Center (the “Jura Center”) in the Canton of Jura.

The proposed Jura Center represents an indicative investment of approximately CHF 40-60 million over a period of six years. The initiative is intended to establish a strategic Swiss capability for the design, personalization, testing and secure provisioning of next-generation post-quantum semiconductor technologies.

At the heart of the project will be SEALSQ's QS7001 Quantum Shield, a secure semiconductor designed to implement post-quantum cryptographic algorithms standardized by the U.S. National Institute of Standards and Technology, including ML-KEM and ML-DSA.

The Jura Center is expected to establish capabilities for cryptographic root-of-trust injection, secure firmware personalization, testing and certification, complemented progressively by ASIC design capabilities.

Building a Swiss Sovereign Semiconductor Capability
The initiative is designed to combine SEALSQ and WISeKey's cybersecurity and semiconductor technologies with the Canton of Jura's longstanding expertise in precision manufacturing, microtechnology and high-quality industrial production.

The project seeks to transfer skills deeply rooted in Jura's watchmaking and microtechnology industries - including precision, quality control and traceability - into secure semiconductor personalization.

The project aims to establish approximately 40 direct jobs within two years, 150 by Year 5 and more than 250 by Year 8. At least 60% of these positions are expected to be filled by residents of the Canton.

A Public-Private Partnership
The Jura Center is expected to be developed as a public-private partnership, with the majority of its financing coming from WISeKey, SEALSQ, private investors and industrial partners. The Canton of Jura would act as a strategic catalyst, facilitating the establishment of the project and evaluating potential support within the applicable cantonal and federal frameworks.

The parties will also explore cooperation with HE-Arc Ingénierie for training, recruitment and applied research and with relevant Swiss technology and industrial organizations.

Building on the Quantix Model
This initiative builds upon the experience of Quantix Edge Security, the EUR 40 million semiconductor design and personalization center being developed in Murcia, Spain, by WISeKey and SEALSQ with Spanish partners.

The Spanish Government, through the Sociedad Española de Transformación Tecnológica (SETT), committed EUR 19.6 million to that public-private initiative in June 2025. The Jura Center intends to adapt the experience and methodologies developed in Murcia to Switzerland's specific industrial and sovereignty requirements.

Strategic Opportunity for Switzerland
The Center will also evaluate opportunities associated with Swiss defense procurement and armasuisse industrial participation programs, where secure semiconductor and ASIC capabilities established on Swiss territory could potentially provide an attractive platform for industrial offset projects.

Secure semiconductors and ASICs are increasingly relevant to avionics, secure communications, sensors and other defense systems, creating an opportunity to strengthen Switzerland's domestic technological and industrial base.

Carlos Moreira, CEO of SEALSQ, said: "The quantum era is transforming cybersecurity into an issue of technological sovereignty. Switzerland must be able not only to design advanced security technologies, but also to personalize, provision and protect the cryptographic roots of trust inside semiconductors on Swiss soil. The Jura has an extraordinary industrial culture built around precision, reliability and microtechnology. Our ambition is to combine this industrial DNA with SEALSQ's post-quantum semiconductor technology and create a new strategic capability for Switzerland. We are already applying this model in Murcia, where the initiative generated initial revenue during the second quarter of 2026. Based on this early commercial progress, believe the Jura Center can become an important European center for post-quantum semiconductor security, creating highly qualified employment, strengthening the regional technology ecosystem while reinforcing Switzerland's technological sovereignty."

Stéphane Theurillat, Minister of Economy of the Canton of Jura added, “This partnership marks an important milestone for Jura and sends a strong signal about our ambition to attract and develop strategic investments. The project combines digital infrastructure with Jura’s strong industrial capabilities and will contribute to further diversifying our economy. It also represents a significant opportunity to strengthen digital sovereignty while creating value and new business opportunities within our regional ecosystem. The Government of the Republic and Canton of Jura strongly welcomes this announcement and is fully committed to supporting the project. Together with the relevant authorities and services, we will work closely with the company to facilitate a fast and successful establishment in Jura and create the conditions for its long-term development.”

Next Steps
Following the MoU, the parties intend to establish a joint working group to develop the detailed business plan, select the site, structure the public-private financing model, develop academic and industrial partnerships, evaluate Swiss federal and armasuisse opportunities, and establish the regulatory and certification roadmap.

The concept envisages the Center operating through a Swiss company incorporated in the Canton of Jura, supported by an appropriate public-private governance structure.

Upon completion of this preparatory work, the Parties intend to move from the MoU to a detailed implementation framework governing the establishment, financing and operation of the Jura Center..
