WISeKey reports 62% revenue growth in 2025 and strong 2026 start with $535M cash reserves.

WISeKey International Holding Ltd reported $19.3 million in revenue for 2025, a 62% increase year-over-year, driven mainly by its SEALSQ subsidiary. The company ended 2025 with $429 million in cash and short-term investments, which grew to over $535 million by April 2026, enabling a strong financial position for long-term growth. WISeKey is transitioning from technology validation to commercial execution, with a commercial pipeline exceeding $200 million for 2026–2029 and plans to begin production revenues from its QS7001 quantum-resistant semiconductor in late 2026. The company also aims to integrate its core business pillars into a unified quantum-secure platform and expand its satellite constellation for quantum-secure cloud services, expecting 50% to 100% revenue growth in 2026.
