SEALSQ and GlobalFoundries Partner to Accelerate Post-Quantum Cryptography and Quantum Computing Technologies

Geneva, Switzerland  -- July 08, 2026  -- SEALSQ Corp (Nasdaq: LAES) ("SEALSQ") and GlobalFoundries (Nasdaq: GFS) (GF) today announced a strategic Memorandum of Understanding (MoU) to co-develop across secure semiconductor platforms, Post-Quantum Cryptography (PQC) and emerging semiconductor-based quantum computing technologies. The partnership leverages GF's process technology leadership and manufacturing capabilities alongside SEALSQ's expertise in hardware-based certified security, PQC-ready silicon solutions and ongoing investments in quantum technologies.

Semiconductor CMOS technology has powered the digital revolution for decades by enabling continuous transistor scaling, higher integration density, and cost-effective mass production. It is now emerging as a key enabler of the quantum era, allowing quantum processors to be built on proven high-volume semiconductor manufacturing platforms that deliver the scalability, reliability, and cost efficiency required for widespread industrial adoption.

The collaboration will focus on developing Post-Quantum Cryptography (PQC) security IP, secure chiplet architectures, and a CryoCMOS ecosystem to support future quantum computing systems, advancing three strategic areas:

• Expanding GF's IP Ecosystem with Certified PQC Security Building Blocks

  In partnership with MIPS, a GF company, the companies will co-develop pre-certified PQC security IP (hard macro) blocks and Chiplet Hardware Security Module (CHSM) components, targeting applications including Hardware Security Modules (HSMs) and Secure Enclaves.

• Advancing Cryogenic CMOS for Quantum Computing

  Building on GF's recently announced Quantum Technology Solutions business and SEALSQ's ongoing ambitions in quantum ASIC design, the companies will collaborate on the design and development of cryoelectronic ASICs operating at ultra-low temperatures for joint clients and partners, leveraging GF’s U.S. manufacturing capabilities and footprint.

• Aligned with Sovereign and Trusted Supply Chain Objectives

  The partnership is designed to support European and U.S. sovereign supply chain priorities. Both companies share a commitment to trusted, traceable, and secure semiconductor production.

“A shared long-term vision between GF and SEALSQ is that semiconductors, cybersecurity, Post-Quantum Cryptography, and quantum computing are converging into a single technology ecosystem,” said Carlos Moreira, CEO of SEALSQ. “GlobalFoundries is one of the world’s leading semiconductor manufacturers, and its growing commitment to security and quantum technologies perfectly complements SEALSQ’s expertise in secure semiconductors, PQC, and our investments across the quantum ecosystem. This partnership is a natural fit and a powerful validation of our shared vision. Together, we have the opportunity to help shape the secure and scalable technology platforms that will power the quantum era.”

“This partnership is about building the foundation for the quantum era: trusted digital infrastructure secured by Post-Quantum Cryptography and the semiconductor technologies that will enable future quantum computing systems,” said Nicholas Sergeant, vice president of Quantum Technology Solutions at GF. “SEALSQ's secure-semiconductor and Post-Quantum Cryptography expertise complements GF's differentiated technology portfolio and expanding quantum capabilities. Together, we are uniquely positioned to give customers and partners the technologies needed to secure and enable the quantum future.”

The initiative builds on GF’s long-standing investments in quantum technologies and complements its new Quantum Technology Solutions business alongside SEALSQ’s investments in quantum computing, reinforcing the critical role of semiconductors in enabling scalable and commercially viable quantum systems.
