Revenue Growth and Strong Balance Sheet Support Outlook

WISeKey reported preliminary unaudited first-half 2026 revenue of about $11.4 million. The result represented a 115% increase from the same period in 2025. Moreover, the growth reflected stronger contributions from post-quantum semiconductors, digital identity solutions, and public key infrastructure services.

The company also ended June with about $495 million in cash and short-term investments. It reported no outstanding debt during the period. The strong balance sheet supports future expansion without immediate financing requirements.

WISeKey reaffirmed its fiscal 2026 guidance and maintained expectations for 50% to 100% annual revenue growth. Additionally, subsidiary SEALSQ reported an active commercial pipeline exceeding $225 million through 2029. The company linked that pipeline to rising demand for post-quantum cryptography products across the United States and Europe.

Quantum Expansion and Satellite Projects Advance

WISeKey expanded its quantum computing strategy through several initiatives during the first half of 2026. The company established Quantisimo Corp. with SEALSQ and signed a non-binding agreement with GigCapital8. Consequently, the proposed transaction targets a Nasdaq-listed quantum computing company valued at approximately $575 million.

The company also advanced its satellite business through WISeSat. A Form F-4 filing moved forward the planned business combination with Columbus Acquisition Corp. WISeSat continued satellite deployments through additional SpaceX launches while preparing for a Nasdaq listing under the proposed ticker SAIQ.

Besides those developments, Quantix officially started operations in Murcia, Spain. The center will focus on semiconductor design, cybersecurity, artificial intelligence, post-quantum technology, and RISC-V systems. Authorities and project teams will now complete technical verification before expanding operations.

Digital Identity, Governance, and Strategic Development

WISeKey strengthened its digital identity business through a partnership with Wecan Group. The collaboration combines secure identity technology with regulated data exchange infrastructure. As a result, the companies aim to provide quantum-resistant identity solutions for financial institutions and regulated industries.

The company also integrated its Quantum RootKey across the SEALQuantum ecosystem. SEALSQ expanded its quantum portfolio through the acquisition of MiraEx and participation in Quobly’s $130 million Series A financing. WISeKey also advanced SEALCOIN, launched the WISeRobot roadmap, and supported WISeSat’s investment in FOSSA Systems.

Corporate developments also continued during the reporting period. WISeKey signed an agreement to redomicile its holding company from Switzerland to the British Virgin Islands. Shareholders approved every proposal during the 2026 Annual General Meeting, including board appointments and governance measures. These updates followed broader progress in cybersecurity, quantum infrastructure, and digital identity, supporting the company’s long-term technology strategy alongside its stronger financial performance.
