SEALSQ Stock Rises on Partnership Announcement with Trusted Semiconductor Solutions

SEALSQ stock rises after announcing a partnership with Trusted Semiconductor Solutions. The partnership was announced on Thursday, while unaudited preliminary results were released on Wednesday.

SEALSQ Corp (NASDAQ: LAES) stock experienced a notable uptick following the announcement of a strategic partnership with Trusted Semiconductor Solutions (TSS) on Thursday, October 9, 2025. This development comes just a day after the release of unaudited preliminary results.

The partnership, formalized at the Quantum + AI Conference in New York, aims to co-develop "Made in US" Post-Quantum Cryptography (PQC)-enabled secure semiconductor solutions tailored for US defense and government agencies. This collaboration leverages TSS's established relationships within the US defense ecosystem and SEALSQ's leadership in post-quantum security, combining advanced quantum-resistant silicon developments and custom chip design capabilities.

The joint roadmap includes short-term integration of SEALSQ's QS7001 secure element with TSS's trusted semiconductor platforms, mid-term co-development of PQC-embedded ICs targeting FIPS 140-3 and Common Criteria certifications, and long-term development of next-generation secure architectures. This partnership underscores SEALSQ's commitment to securing digital infrastructures in the post-quantum era and its strategic alignment with the US semiconductor industry.

Carlos Moreira, CEO of SEALSQ, emphasized the significance of the partnership, stating, "This marks a pivotal step in SEALSQ’s US strategy. TSS is an ideal Trusted-accredited partner already addressing US defense and government agencies to work with and combine our leadership in post-quantum security with America’s trusted semiconductor ecosystem to build the foundation for sovereign, quantum-resistant digital infrastructure."

Allan T. Hurst, President and CEO of Trusted Semiconductor Solutions, added, "SEALSQ is truly unique — not only in its post-quantum technology but also in its business model and security vision. Its ability to combine catalog secure products, advanced IP, and custom IC design capabilities sets it apart in the semiconductor industry. By integrating SEALSQ’s PQC innovation into our defense-grade solutions, we could deliver unmatched trust and resilience to our Agency partners and ensure that critical US systems remain secure in the quantum era."

This partnership is part of SEALSQ's broader "Quantum Corridor" initiative, which links its innovation hubs across Europe and the US. The collaboration is expected to bolster SEALSQ's market position and provide a competitive edge in the rapidly evolving semiconductor industry.
