SEALSQ Corp (Nasdaq: LAES) develops post-quantum cryptography semiconductors and security solutions for IoT and connected devices.

In March 2026 it expanded its Quantum Fund, launched in 2025, to 200 million dollars, with more than 30 million dollars already deployed, targeting quantum companies and technologies across photonics, quantum networking, and quantum sensing. That same month, SEALSQ signed a Letter of Intent to acquire Miraex SA, a Swiss developer of photonics-based quantum interconnect solutions using Thin Film Lithium Tantalate technology.

The acquisition completed on 2 June 2026.

At 30 June 2026 SEALSQ held 486.1 million dollars in cash, cash equivalents and restricted cash, and its H1 2026 revenue rose 131 percent to 11.2 million dollars.

In November 2025 it launched the Quantum Shield QS7001, a post-quantum secure element; in September 2026 the company said all versions were still available as engineering samples, with Common Criteria test reports targeted for October 2026 and January 2027.

The company reported 66 percent revenue growth in FY2025, inaugurated India's first PQC personalization center with Kaynes Semicon, and expanded its quantum fund to 200 million dollars. It has guided to FY2026 revenue of 27 to 36 million dollars.

SEALSQ pushed back its certification timetable: the QS7001 Common Criteria test reports are now targeted for October 2026 (V1) and January 2027 (V2), and TCG certification of the QVault TPM-183 and TPM-185 for February and May 2027, with all versions available as engineering samples. sec.gov
