SEALSQ Announces that Quantix Selects the Municipality of Murcia as the Location for Its Semiconductor Industrial Project in the Region

Murcia, Spain / Geneva, Switzerland, May 26, 2026 (GLOBE NEWSWIRE) --

Quantix highlights the high quality of the applications submitted and the Region’s strong capacity to attract major industrial projects

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 that QUANTIX EDGE SECURITY has selected the municipality of Murcia as the location for its semiconductor design industrial center project in the Region of Murcia, following the completion of a technical evaluation process in which 25 applications from 15 municipalities were assessed.

Quantix would like to express its gratitude to all participating entities, highlighting the exceptionally high standard of the proposals submitted both in the initial phase and in the final stage.

The eight finalist municipalities — Abarán, Alhama de Murcia, Alcantarilla, Caravaca, Cartagena, Ceutí, Jumilla, and Murcia — presented projects of outstanding quality, requiring an especially thorough analysis and contributing to an extended final selection timeline.

This process has demonstrated the Region of Murcia’s strong ability to attract and promote high value-added industrial initiatives, consolidating its position as a competitive environment for the development of strategic technological projects.

In this context, QUANTIX identified a location that meets the necessary requirements to move forward confidently with the implementation of a strategic industrial infrastructure, with an estimated investment of €40 million dedicated to the design, testing, personalization, and security of semiconductors.

The Location
The selected site in the municipality of Murcia stands out due to a combination of key factors supporting the implementation of the project, as well as its alignment with the company’s strategy to strengthen R&D&I (Research, Development and Innovation) as a core element of its growth.
The choice of this location therefore responds not only to technical and industrial criteria, but also to its ability to host and enhance an advanced innovation model.

Among the determining factors of the site are:

1. Effective availability of fully serviced industrial land with sufficient capacity to accommodate an industrial infrastructure with scalability potential.
2. Access to utilities and supplies consistent with the requirements of an advanced technological facility.
3. Optimal logistics and communication conditions for both the construction phase and future operations.
4. A favorable technical, academic, and talent ecosystem that supports the project’s development and the promotion of R&D&I initiatives.

The Project
The QUANTIX project involves an estimated investment of €40 million dedicated to the development of a Semiconductor Design and Personalization Center in the Region of Murcia, with advanced capabilities in cybersecurity, post-quantum technology, AI, and RISC-V systems.

Quantix is a joint venture with SETT.ES holding a 49% stake, with OdinS and TProtege owning 25.5%, and WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY), a global leader in cybersecurity, digital identity and IoT together with SEALSQ holding a combined 25.5 %.  The venture includes the Murcia-based OdinS, a spin-off from the University of Murcia, TProtege, the Switzerland-based WISeKey and its subsidiary, the majority France-based SEALSQ, both listed on NASDAQ.

The initiative will support the development in the Region of Murcia of an advanced infrastructure focused on semiconductor solutions for strategic sectors such as defense, critical infrastructure, automotive, and IoT, among others.

In terms of employment, the project is expected to progressively generate highly qualified jobs linked to specialized technical profiles, with growing impact as implementation advances.

The project is part of the broader context of strengthening European technological autonomy and Spain’s national strategy to promote the semiconductor industry.

Next Steps
QUANTIX will present, during a press conference to be held in the coming days, the technical factors that guided the identification of the location, details regarding the exact site, and the general characteristics of the project.

At the same time, the company will begin an in-depth technical verification phase together with the relevant public administrations, aimed at defining the operational, administrative, and infrastructure-related aspects necessary for the project’s development.

Progress during this phase will allow for a more precise definition of the execution timetable, in line with the industrial and regulatory requirements of an initiative of this nature.

A presentation detailing the exact location and the characteristics of the future center will be held in the coming weeks.
