WISeKey International Holding Ltd (Nasdaq: WKEY) reported preliminary unaudited revenue of approximately $11.4 million for the first half of 2026, representing a 115% increase compared to the same period in 2025, according to a press release issued July 13, 2026.

The company reported approximately $495 million in cash and short-term investments as of June 30, 2026, with no debt. WISeKey reaffirmed its full-year 2026 guidance of 50% to 100% revenue growth. The figures are preliminary and subject to completion of half-year closing procedures, with full results expected in September 2026.

Subsidiary SEALSQ holds a commercial pipeline that management estimates at more than $225 million through 2029, driven by demand for post-quantum cryptography products. The company noted pipeline figures are subject to conversion risks, customer validation, and technical integration factors.
