Future Outlook

SEALSQ anticipates significant growth in the semiconductor market, projected to reach $1 trillion by 2030, driven by increasing demand for hardware-based security. The company expects 2026 to be a critical compliance year due to the EU Cyber Resilience Act and NSA CNSA 2.0 mandates, which will drive adoption of hybrid cryptography and quantum-resistant solutions. SEALSQ plans to commercially deploy its post-quantum-resistant chips in the latter half of 2026 and launch the QVault TPM in 2026. The company intends to establish two additional Custom Design, Test, and Personalization hubs in the US and Asia in 2026, and expects to generate revenue from the Quantix Edge Security project in Spain. Future efforts include enhancing network performance and reducing high cybersecurity vulnerabilities by 70%.

Management Comments

• Management believes that the QUASAR project, together with its M&A strategy to broaden its competence base (e.g. ICAlps adding ASIC design to SEALSQs service offering) and strategic investments in developing technologies and industries such as quantum computing (EeroQ, ColibriTD), decentralized data infrastructure (WeCan Group) and secure satellite services (WISeSat), are essential to future revenue growth.
• Management believes that such equity grants are an important incentive to recognize and reward the commitment of the company's staff.
• Management believes it is correct to present these figures on a going concern basis.
• Management believes that 2026 is a critical compliance cliff for two major reasons: 1. EU Cyber Resilience Act (CRA) Deadlines... 2. CNSA 2.0 Networking Compliance...
• SEALSQ believes that a major 2026 trend will be the creation of sovereign post-quantum Roots of Trust.
• SEALSQ believes that manufacturing PKI will focus on Zero-Touch Provisioning (ZTP) and localized trust anchors given the following industry trends.
• SEALSQ believes that the IoT Device Identity market will reach a critical inflection point in 2026, with the global PKI market projected to be worth approximately $8.48 billion growing at a 20.5% CAGR until 2035.

Industry Context

StockSavvy.ai notes that SEALSQ's strong revenue growth and strategic investments in post-quantum cryptography and ASIC design align with the broader semiconductor industry's shift towards hardware-based security and the increasing demand for secure, tamper-resistant solutions in IoT, automotive, and critical infrastructure. The company's focus on NIST-standardized PQC algorithms and certifications positions it well against emerging quantum threats, a critical trend driven by regulatory mandates like NSA CNSA 2.0 and the EU Cyber Resilience Act. The expansion into specialized ASIC design through ICAlps and investments in quantum computing startups like EeroQ reflect a proactive strategy to capture market share in high-growth, high-security niches, differentiating it from general-purpose chip manufacturers.

Key Dates

Recommendation

SEALSQ is navigating a high-growth, high-risk transition period. While the company has demonstrated strong strategic vision and execution in securing significant capital and launching innovative post-quantum cryptography products, the substantial increase in net losses and operating expenses in FY2025 is a concern. The long-term potential in quantum-resistant security and ASIC design is compelling, but the inherent volatility of the semiconductor and digital asset markets, coupled with regulatory uncertainties and customer concentration, warrants a cautious approach. Investors should monitor the commercialization of new products and the path to profitability before considering a stronger position.
