SEALSQ Corp (NASDAQ: LAES) specializes in post-quantum semiconductors, public key infrastructure (PKI), and trusted provisioning solutions. The company is actively investing in quantum security through its SEALQUANTUM initiative and has also expanded its partnership with the BWT Alpine Formula One Team.

On September 11, 2026, SEALSQ announced its financial and operational results for the six-month period ended June 30, 2026. The company reported a basic and diluted loss of $0.13 per ordinary share, compared with a loss of $0.17 per ordinary share in H1 2025.

SEALSQ posted revenue of $11.2 million for H1 2026, up 131% from $4.8 million in the same period last year. During the same period, gross profit rose 233% to $5.4 million, while gross margin expanded to approximately 48%. Revenue growth was supported by demand for Vault-IC secure-element products, PKI subscriptions, digital identity services, and revenue from IC’Alps SAS.

The company still remains unprofitable. SEALSQ recorded a net loss of $27.8 million in H1 2026, compared with a net loss of $20.0 million in H1 2025. This wider loss reflects higher spending on research and development, acquisition integration, product certification, and its post-quantum technology roadmap.

SEALSQ’s negative P/E ratio of -9.55 also reflects its lack of profitability over the past year. However, the company’s balance sheet remains strong, with $486.1 million in cash, cash equivalents, and restricted cash as of June 30, 2026. Its current ratio of 14.43 indicates significant short-term liquidity, while its low debt-to-equity ratio of 0.013 shows limited leverage.

Looking ahead, SEALSQ reaffirmed its FY2026 revenue guidance of $27 million to $36 million. The company expects future growth to be supported by continued demand for secure semiconductors, PKI services, post-quantum products, and custom ASIC design programs.
