SEALSQ Corp Confirms 2025 Revenue Guidance and Projects Strong Growth Acceleration for 2026

Geneva, Switzerland, Nov. 18, 2025 (GLOBE NEWSWIRE) --

Strong Balance Sheet of over $430 Million in Cash Supports Global Quantum Ecosystem Expansion

SEALSQ Corp (NASDAQ:LAES) ("SEALSQ" or the "Company"), a leader in Semiconductors, PKI, and Post-Quantum technology today is reaffirming its full-year 2025 revenue guidance and announced expectations for a meaningful acceleration in growth for 2026, driven by expanding customer demand, the impact of the acquisition of IC'Alps and the scaling of its post-quantum product roadmap.

Reaffirmed 2025 Guidance and 2026 Outlook

Following solid revenue growth for the first nine months of 2025, where SEALSQ recorded preliminary revenues of $9.9 million, representing a 41% increase compared to the same period in 2024, with $5.1 million generated in Q3 2025 alone, the Company expects this trend to continue in the fourth quarter of the year.

The year-to-date growth was driven primarily by renewed demand for traditional SEALSQ products and the consolidation of two months of revenue from IC'ALPS, following its acquisition on August 4, 2025. During the year, despite the ongoing transition from legacy products to next-generation post-quantum semiconductors and software, the Company continues to strengthen its commercial base and technological roadmap.

Thus the Company reaffirmed its full year 2025 revenue guidance of $17.5 million to $20.0 million, representing expected full-year growth of 59% to 82% over full year 2024.

Looking ahead, SEALSQ anticipates strong acceleration in 2026, forecasting 50% to 100% revenue growth for the year as compared to full year 2025, driven by:

• The full effect of newly launched PQC chips
• Complete consolidation of IC'ALPS operations
• Ramp-up of Quantix Edge revenues
  
  
  
  

With a business pipeline now exceeding $175 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.

Carlos Moreira, CEO of SEALSQ, commented, "Our 2025 guidance and expectations for significant growth for 2026 underscore the strength of our commercial strategy, technology roadmap, and market position. 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 $430 million, even after deploying $30 million toward strategic investments in IC'ALPS and WISeSat earlier this year. These investments strengthen 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.

With strong liquidity and growing commercial momentum, SEALSQ is accelerating initiatives across the semiconductor, cybersecurity, and satellite IoT markets, positioning the Company to capture increasing demand for post-quantum security infrastructure from governments, enterprises, and critical-industry partners worldwide.

SEALSQ enters this next growth phase with the financial strength required to scale production, accelerate R&D in PQC technologies, and expand its global footprint. The Company remains focused on meeting the rising demand for secure, quantum-ready infrastructure while solidifying its position as a global leader in the emerging quantum-security ecosystem.

Key Product Milestones and Strategic Initiatives

SEALSQ confirmed the upcoming launch of WISeSat 3.0 PQC on November 18, 2025, and Quantum Shield QS7001™ as well as the planned go-live of its Post-Quantum Root of Trust on November 21, 2025, marking major milestones that aim to further solidify its leadership in post-quantum security technologies.

In parallel, the integration of IC'ALPS and deployment of the Quantix Edge Security partnership are expected to provide additional scale, broader capabilities, and deeper market penetration.

Made in USA Strategy

SEALSQ's U.S.-based Post-Quantum Root of Trust goes live on Friday, November 21, 2025. This sovereign infrastructure is designed to allow American enterprises and government agencies to issue, manage, and validate quantum-resistant digital identities and PKI services entirely on U.S. soil.

Quantum computers are set to disrupt current security systems, including RSA, threatening sectors from banking and defense to healthcare and IoT. Any system deployed or data encrypted today will be exposed within 3 to 10 years.

The U.S. government is acting swiftly. Under the NSA's CNSA Suite 2.0, all new National Security Systems must adopt quantum-resistant solutions by 2027, with full transition of national-security-grade cryptography targeted by 2035.

SEALSQ is increasingly approached by US companies, and it believes itself to be uniquely positioned to meet this demand, offering certified hardware, cryptographic expertise, and semiconductor capabilities to help U.S. companies achieve compliance with emerging quantum-security standards.
