WISeKey International Holding AG released its preliminary FY 2025 financial results, reporting total revenue of $19 million—a 58% year‑over‑year increase from $12 million in FY 2024. The fourth‑quarter revenue doubled to $8 million, driven by growth in the company’s semiconductor and public‑key infrastructure (PKI) product lines and early commercial traction of its post‑quantum chip programs.
The company’s cash balance as of December 31 2025 was $425 million, a substantial jump from the $124.6 million reported in the June 30 2025 interim statement. This liquidity boost reflects continued investment in quantum‑secure semiconductor and satellite initiatives while providing a strong financial cushion for the next phase of commercial expansion.
Despite the revenue growth, WISeKey’s operating and net margins remained negative, consistent with the company’s ongoing investment strategy. The margin compression is attributed to significant R&D and capital expenditures required to bring new post‑quantum products to market, offsetting the revenue gains from the semiconductor and PKI segments.
Management guided for FY 2026 revenue growth of 50% to 100% year‑over‑year, citing a pipeline of more than $200 million in potential revenue opportunities. The guidance signals confidence in sustained demand for quantum‑resistant solutions and the company’s ability to convert its pipeline into revenue while maintaining its liquidity position.
The market reacted positively, with the stock rising 8.8% after the announcement. Investors were driven by the strong revenue growth, the significant increase in cash reserves, the robust pipeline, and the optimistic FY 2026 guidance, all of which underscore WISeKey’s transition from a “reset” year to a commercial acceleration phase.
"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." – Carlos Moreira, Founder & CEO
