SEALSQ Corp reports nine-month 2026 revenue reached $16.3 million, a 65 percent increase compared to the same period last year. The company anticipates fourth-quarter revenue between $11 million and $20 million, resulting in a full-year revenue range of $27 million to $36 million, exceeding the $18 million reported in 2025. “Our preliminary nine-month revenue of $16.3 million represents 65% growth year-over-year,” said Carlos Moreira, Founder, Chairman and CEO of SEALSQ, as the company prepares to fund further development of its post-quantum semiconductors with approximately $465 million in liquidity.
SEALSQ’s 9M 2026 Revenue Growth Driven by Post-Quantum Products
The company’s financial position supports continued investment in post-quantum semiconductor development, with approximately $465 million in liquidity as of the nine-month mark in 2026. This capital reserve will fund ongoing priorities as the company anticipates increased revenue from its post-quantum product lines starting in 2027, dependent on customer integration and production scaling.
Laboratory review, certification, and customer procurement timelines are key factors influencing the pace of deployment. John O’Hara, CFO, stated, “Based on our preliminary nine-month revenue, our reaffirmed full-year 2026 revenue guidance implies fourth-quarter revenue of $11 million to $20 million.” The company’s products aim to safeguard sensitive data across sectors including multi-factor authentication, energy, healthcare, defense and industrial automation, embedding post-quantum cryptography directly into semiconductor solutions to enhance resilience.
The company’s focus on post-quantum semiconductors reflects a proactive approach to a potential cryptographic threat, as traditional methods like RSA and elliptic curve cryptography become increasingly susceptible to attacks from quantum computers. The design philosophy prioritizes future protection for critical systems, positioning the company to benefit from the growing demand for quantum-resistant security solutions. With substantial liquidity and a clear roadmap for commercialization, the company appears well-positioned to establish itself as a key player in the emerging post-quantum security market.
Our preliminary nine-month revenue of $16.3 million represents 65% growth year-over-year, with revenue increasing sequentially in each quarter of 2026.
