* Reflects potential revenue opportunities with both current and potential new customers from 2026 through 2028, including more than $60 million linked to QS7001 and QVault TPM programs.
FY 2025 revenue growth was driven by increased demand across core secure semiconductor and PKI product lines, five months of IC'ALPS contribution, and early commercial traction in post-quantum semiconductor programs. FY 2025 marked the final phase of transition from legacy platforms toward next-generation post-quantum semiconductor architectures, now entering a phase of commercial acceleration.
Carlos Moreira, Founder & CEO, WISeKey and SEALSQ, noted, "The 58% revenue growth for WISeKey achieved in 2025 and the strong start into 2026 clearly demonstrate the transition of our semiconductor and post-quantum strategy from investment to commercial acceleration. With exceptional liquidity, a rapidly expanding pipeline, and rising global demand for sovereign, quantum-resistant infrastructure, WISeKey and SEALSQ are uniquely positioned to lead the next generation of secure digital ecosystems."
FY 2026 Outlook & Commercial MomentumWISeKey has now entered its commercial acceleration phase. Its year end pipeline of over $200 million in potential revenue opportunities from 2026 through 2028, includes more than $60 million linked to QS7001 and QVault TPM programs, reflecting rising global demand for quantum-resistant security and sovereign semiconductor design solutions.
Q1 2026 revenue is expected to exceed $4M, representing over 100% growth versus Q1 2025. WISeKey also confirms that it expects FY 2026 revenue growth of +50% to +100% year-over-year.
Key growth drivers for 2026:
Commercial rollout of QS7001 post-quantum secure chips and QVault TPM, with initial revenues expected in late 2026.
Full-year consolidation of IC'ALPS revenues.
Expansion into the Trusted Platform Module (TPM) market.
Launch of custom post-quantum ASIC development programs.
Increased global adoption of PQC driven by quantum computing threats and U.S. NSA ...
