The partnership operates on a three-phase timeline. Phase one integrates SEALSQ’s QS7001 secure element with TSS’s trusted semiconductor platforms.
Later phases will develop U.S.-manufactured post-quantum cryptography embedded chips. These chips require multiple certifications for defense applications.
The final stage targets advanced secure architectures for next-generation defense systems. TSS will handle relationships with U.S. government agencies.
SEALSQ contributes its quantum-resistant silicon technologies. The company also provides secure-chip expertise from years of cryptography work.
The two companies plan to formalize the alliance at the Quantum + AI Conference in New York City. SEALSQ serves as Diamond Sponsor for the event.
Financial Performance and Cash Position
SEALSQ reported revenue of $9.9 million for the nine months ending September 30, 2025. This represents 41% growth compared to the same period last year.
The revenue increase came from two sources. Demand for traditional products picked up after a slower period.
The acquisition of IC’ALPS also boosted revenue. The company continues managing the transition to next-generation technologies.
SEALSQ holds $220 million in cash as of October 7, 2025. This positions the company to expand its post-quantum cryptography semiconductor offerings.
Average trading volume sits at 12.6 million shares. Technical indicators currently show a buy signal.
The most recent analyst rating is a Hold with a price target of $4.50. Year-to-date, the stock trades roughly flat.
Quantum Security Interest Rises
The timing aligns with renewed interest in quantum physics. The 2025 Nobel Prize in Physics went to three scientists for quantum tunneling research.
Their work demonstrated quantum-level particles passing through barriers in large-scale electrical circuits. This research has increased focus on real-world quantum applications.
One user noted the combination of quantum security and defense contracts as highly lucrative. Another suggested institutional investors might start buying the stock now that it trades above $5.
The partnership fits SEALSQ’s “Quantum Corridor” strategy. This initiative connects the company’s innovation hubs in the United States and Europe.
Under the deal, TSS leads on interfacing with government agencies while SEALSQ provides the technology platform. The division leverages each company’s strengths in the defense semiconductor space.
