Strategic Initiatives
Growth programs, investments, and their expected impact
A comprehensive 'root-to-qubit' architecture strategy designed to integrate classical computing, post-quantum cryptography (PQC), and native quantum processing into a unified, secure sovereign platform.
Expected impact: Establishes SEALSQ as a cornerstone player at the intersection of secure semiconductors, post-quantum cryptography, and quantum technologies.
Expansion of localized U.S. operations, including the development of a sovereign U.S. Quantum RootKey and strategic partnerships to deliver secure, post-quantum-ready semiconductor solutions for the U.S. government and defense ecosystem.
Expected impact: Aligns SEALSQ's technology with national security and regulatory requirements, opening up high-value government and defense contracts.
Mergers, Acquisitions & Partnerships
Recent deals and strategic collaborations
Recent Acquisitions
Acquisition of 100% of the Swiss photonics developer closes the quantum interconnect layer of SEALSQ's Quantum Sovereign Vertical Stack, bridging quantum computing hardware and quantum communication networks.
Financial impact: Funded through the SEALSQ Quantum Fund. Integrates Miraex's Thin Film Lithium Tantalate (TFLT) Photonic Integrated Circuit (PIC) platform directly into SEALSQ's hardware roadmap.
Acquisition of a leading French ASIC design specialist to add custom chip design expertise for healthcare, automotive, and IoT, and position SEALSQ to develop the QASIC (Post-Quantum cryptography ASIC).
Financial impact: Contributed approximately $3.5 million to FY 2025 revenues (five months of consolidation) and is expected to drive full-year revenue growth in FY 2026.
Strategic Partnerships
SEALSQ co-led a Series A funding round for Quobly to industrialize silicon-based quantum processors. The partnership integrates post-quantum cryptography and hardware Root-of-Trust into silicon-based quantum architectures.
Terms: SEALSQ invested EUR 14,999,400 via the SEALSQ Quantum Fund for Series A preferred shares with attached anti-dilution ratchet warrants.
Deepens technology and capital relationship to develop an integrated Quantum Security Vertical Stack combining SEALSQ's secure semiconductor hardware with EeroQ's helium-based quantum processor architecture.
Terms: SEALSQ acted as the lead investor in EeroQ's upcoming financing round, following previous strategic investments in December 2025 and February 2026 funded via the SEALSQ Quantum Fund.
