| · | Growth drivers: this 41% growth is mostly attributable to the expected return to growth in the demand for our traditional products and two months of consolidated revenue from IC’ALPS since the completion of the acquisition on August 4, 2025. However, our revenue is still negatively impacted by the ongoing transition from legacy products to next-generation post-quantum semiconductors and software. | |
| · | Treasury: a cash position of $220 million as of October 7, 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 2025 Revenue Outlook and Growth Catalysts
| · | 2025 Guidance: Full-year revenue expected between $17.5 million and $20.0 million, marking 59%–82% growth over 2024. This full-year outlook includes the expected return to growth in the demand for our traditional products, the consolidated revenue of IC’ALPS since the completion of the acquisition on August 4, 2025, as well as our best estimate of the start date for the Quantix Edge Security project. | |
| · | 2026 and Beyond: Anticipated continued acceleration, with an expectation of between 50% to 100% growth, propelled by new PQC chip launches, full consolidation of IC’ALPS, and Quantix Edge revenues. | |
| · | Pipeline: The Company’s expanding business pipeline now totals $175 million in potential revenue opportunities from 2026 to 2028, highlighting rising global demand for quantum-resistant security and sovereign semiconductor design and the continued evolution of our business development activities. |
CEO Commentary
Carlos Moreira, CEO of SEALSQ, stated: "While 9M 2025 revenue continues to reflect our strategic transition to the post-quantum era, third quarter 2025 revenue alone surpassed total revenue for the first half of the year and we expect the fourth quarter of 2025 to continue this trend. Thus, we expect fourth quarter revenues to be between $7.6 million and $10.1 million, with our full year 2025 revenue guidance of between $17.5 million and $20.0 million, fueled by commercial projects and the consolidation of IC’ALPS results. With Quantum Shield QS7001™ and QVault™ TPM solutions entering production in 2026, SEALSQ is entering its growth phase."
Mr. Moreira added: "Our foundation, including Personalization Centers in Europe and global PQC leadership, positions SEALSQ at the heart of the digital trust revolution. We are building a secure, connected, and quantum-resilient future."

Major Progress Toward Quantum-Resilient Security Infrastructure
SEALSQ has made major progress in its mission to deliver trusted hardware security modules designed for the quantum future.
The urgency is clear. The U.S. Government has set strict timelines for adopting quantum-resistant cryptography. Under the National Security Agency’s CNSA 2.0 policy, all new National Security Systems acquisitions must be compliant by January 1, 2027, with broader enforcement milestones extending into the next decade.
Complementing this, the Office of Management and Budget Memorandum M-23-02 requires all federal agencies to identify quantum-vulnerable systems and prepare migration budgets, placing Post-Quantum Cryptography (PQC) at the center of national cybersecurity policy.
In parallel, the National Institute of Standards and Technology (NIST) finalized the first PQC standards in August 2024, including:
| · | FIPS 203 (ML-KEM) for key establishment | |
| · | FIPS 204 (ML-DSA) and FIPS 205 (SLH-DSA) for digital signatures |
These standards form the backbone of next-generation secure infrastructures, accelerating the global migration toward PQC and underscoring SEALSQ’s leadership role in delivering compliant, forward-compatible semiconductor solutions
