SEALSQ Announces FY 2025 Preliminary Unaudited Key Operational and Financial Metrics
Strong Balance Sheet With Over $425 Million in Cash Supports Global Quantum Ecosystem Expansion; $200 Million Pipeline Over the Next Three Years Supports Long-Term Growth
Geneva, Switzerland, January 13, 2026 — SEALSQ Corp (NASDAQ: LAES) (“SEALSQ” or the “Company”), a leader in Semiconductors, PKI, and Post-Quantum technology today announced full-year (FY) 2025 key operational and financial metrics (all financial data are preliminary and unaudited).
FY 2025 Revenue and Financial Highlights:
| · | +66% year on year revenue growth: Preliminary unaudited 2025 revenue of $18 million, with $8 million recorded in the fourth quarter of the year, compared to $4 million in the equivalent period last year. |
| · | Growth drivers: The growth was driven primarily by renewed demand for traditional SEALSQ products and the consolidation of five months of revenue from IC’ALPS, following its acquisition on August 4, 2025. During the year, the Company continued to strengthen its commercial base and technological roadmap, however, revenue remained adversely impacted by the ongoing transition from legacy products to next-generation post-quantum semiconductors and software. |
| · | Treasury: Cash position of over $425 million as of December 31, 2025 provides strong liquidity for PQC innovation and expansion, with the Company aiming to solidify its leadership in PQC-enabled semiconductors and its capacity to meet growing global demand for sovereign, quantum-secure technologies. |
FY 2026 Outlook and Pipeline
| · | 2026 Revenue Guidance: The Company reiterates its previously announced FY 2026 revenue growth of between 50% and 100% year-over-year. This incorporates the expected return to growth for current products, a full year of revenue from IC’Alps, as well as initial revenues from the new QS7001 range of products, further new PQC chip launches, and initial revenues from the Quantix Edge project. |
| · | Pipeline: The Company’s expanding business pipeline now totals over $200 million in potential revenue opportunities from 2026 to 2028; this includes over $60 million of opportunities from QS7001 and Qvault TPM products. This pipeline highlights rising global demand for quantum-resistant security and sovereign semiconductor design and the continued evolution of business development activities. |
Carlos Moreira, CEO of SEALSQ, commented, “Our 2025 revenue and expectations for further significant growth for 2026 underscore the strength of our commercial strategy, technology roadmap, and market position. With a business pipeline now exceeding $200 million in potential opportunities from 2026 to 2028, SEALSQ is positioned to capture growing global demand for quantum-resistant security, sovereign semiconductor capabilities, and next-generation trust technologies. We are well-positioned to capture growing demand from governments, enterprises, and critical industries for secure, quantum-ready infrastructure. Backed by a robust financial foundation, SEALSQ is focused on scaling production, accelerating R&D, and expanding our global footprint, solidifying our role as a leader in the emerging quantum-security ecosystem.”
Strong Financial Position Supports Growth Initiatives
The Company reported that cash reserves have surpassed $425 million at December 31, 2025, even after deploying $30 million during the year toward strategic investments in WeCan Group, IC’ALPS, Quantix Edge and WISeSat.Space (WISeSat), a leader in secure satellite and critical digital satellite infrastructure, another subsidiary of its parent company, WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company. These investments have strengthened SEALSQ’s vertical integration across chip design, secure hardware, and quantum-resilient connectivity, while the Company’s robust balance sheet provides exceptional financial flexibility to support ongoing global expansion.
| · | The strategic acquisition of IC’ALPS, a leading French ASIC design specialist, for a fixed purchase price of EUR 12.5 million (with potential earn-out up to EUR 4 million) has significantly bolstered SEALSQ’s custom chip design capabilities, adding approximately 90 highly skilled engineers and expanding the Company’s footprint in Europe’s semiconductor ecosystem, particularly in Grenoble and Toulouse. |
| · | Additionally, the $10 million strategic investment in WISeSat AG is accelerating the deployment of a secure, quantum-ready satellite constellation, aimed at enabling space-based Quantum Key Distribution (QKD) communications, decentralized IoT transactions, and enhanced post-quantum security for global connectivity. |
| · | A partnership with ColibriTD for quantum-as-a-service solutions, aims to offer a full panel of Quantum related services in applications such as automotive, medtech and space. |
| · | The strategic investment in EeroQ, a U.S.-based quantum chip design company pioneering a breakthrough approach to building a quantum computer using electrons on helium (eHe), is a key step in SEALSQ’s ‘Quantum Made in USA’ industrial strategy. |
Advancements in Smart Meter and PKI Solutions
SEALSQ is making significant strides in its smart meter and Public Key Infrastructure (PKI) offerings, which are expected to contribute substantially to 2026 revenue growth through recurring contracts and expanded deployments.
Key highlights include:
| · | Smart Meter Progress: Building on multi-year supply agreements, SEALSQ has extended its partnership with Landis+Gyr to deliver enhanced PKI services for Advanced Metering Infrastructure (AMI) networks and secure over 24 million smart metering devices as part of the UK Smart Metering Implementation Programme (SMIP). Additional deployments are underway across Asia Pacific, North America, and Europe, incorporating VaultIC secure microcontrollers for robust data protection. These initiatives align with global energy regulations, such as EU cybersecurity standards, and are projected to generate recurring revenue from certificate management and device provisioning, with initial pilots scaling to full production in 2026. |
| · | PKI Services Expansion: The Company has secured significant contracts with leading utilities and smart home providers, including Hager, Wago, Delta Dore, Warema, Tedee, and Digi, driving revenue growth through scalable digital trust solutions. These partnerships leverage SEALSQ’s INeS PKI platform for code signing, firmware integrity, and Matter-compliant device attestation, ensuring compliance with RED and CRA regulations. Integration of post-quantum cryptography is accelerating adoption, positioning SEALSQ to capture emerging demand in IoT ecosystems and generate multi-year subscription-based revenues as clients transition to quantum-ready security infrastructures worldwide. |
These advancements not only strengthen SEALSQ’s market position in energy and connected devices but also support the Company’s broader quantum ecosystem strategy, with significant contributions to the 2026-2029 revenue pipeline.
