Geneva, Switzerland – February 17, 2026 - SEALSQ Corp (NASDAQ: LAES) (“SEALSQ” or the “Company”), a global leader in semiconductor, PKI, and post-quantum security technologies, today announces key preliminary operational and financial metrics for fourth quarter (“Q4”) and full year (“FY”) 2025, provides first quarter 2026 revenue expectations, and reaffirms FY 2026 revenue guidance. All numbers reported are preliminary and unaudited. The Company expects to publish its audited full-year financial statements on or before March 31, 2026.
FY 2025 Key Financial and Operational Highlights
| · | FY 2025 revenue reached $18 million, representing a 66% increase year-over-year, of which $8 million was generated in Q4 2025, as compared to $4 million in Q4 2024. Revenue growth was driven by renewed demand across core semiconductor and PKI product lines, five months of revenue contribution from IC'ALPS SAS (“IC’ALPS”) following its acquisition on August 4, 2025, which represented approximately $3.5 million and early traction in post-quantum technology programs. While 2025 numbers reflected the continued transition from current generation product offerings to next-generation post-quantum semiconductor platforms, that transition has now entered its commercial acceleration phase. |
| · | FY 2025 net loss is expected to be in range of $30 – 40 million, representing an increase in loss against the FY 2024 net loss of $21 million. The 2025 net loss includes further investment in our research & development, and sales & marketing efforts designed to accelerate growth with the launch of the new post-quantum semiconductor product range, increased operating expenses due to the consolidation of IC’ALPS since August 2025 as well as a non-cash Share Based Compensation charge of approximately $9 million . |
| · | Ended the year with a strong balance sheet. As of December 31, 2025, SEALSQ held over $425 million in cash, providing one of the strongest liquidity positions in its sector, even after deploying $30 million during the year toward strategic investments in WeCan Group, IC’ALPS, Quantix Edge and WISeSat.Space (WISeSat), a secure satellite and critical digital satellite infrastructure company and a subsidiary of SEALSQ’s parent company, WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company. This capital base enables accelerated post-quantum R&D, manufacturing scale-up, strategic acquisitions and ecosystem investments and vertical integration in ASIC design and quantum infrastructure. |
| · | Active business pipeline estimated to total over $200 million as of December 31, 2025, reflecting potential revenue opportunities with both current and potential new customers from 2026 through 2028, including more than $60 million linked to QS7001 and QVault TPM programs. This pipeline highlights rising global demand for quantum-resistant security and sovereign semiconductor design and the continued evolution of our business development activities. These figures reflect management estimates and are subject to conversion risks, customer validation, and technical integration amongst other topics. |
Carlos Moreira, CEO of SEALSQ, stated: “Our 66% revenue growth in 2025, combined with initial expectations of Q1 2026 revenue exceeding $4 million, mark a clear inflection point for SEALSQ. We are transitioning from a development and investment cycle into a structured commercial acceleration phase. With more than $425 million in cash, an estimated $200+ million of new potential revenue opportunities pipeline, and growing global demand for quantum-resistant infrastructure, SEALSQ is strategically positioned to become a cornerstone player in sovereign semiconductor and quantum-security ecosystems worldwide.”
SEALSQ Enters 2026 Well Positioned for Structural Growth and Commercial Acceleration
SEALSQ has entered 2026 with clear commercial momentum. The Company remains focused on scaling production, accelerating post-quantum innovation, expanding global partnerships, and securing its role as a leader in the emerging quantum-security infrastructure market. Q1 2026 revenue is expected to exceed $4 million, representing a substantial increase of over 100% on Q1 2025 and signaling accelerated demand across our traditional product portfolios, as our pipeline continues to grow with opportunities. Specifically, the anticipated Q1 2026 growth reflects expected increased revenue from Vault-IC secure element technology increasing as more objects require Internet secure connections and the full-quarter consolidation of IC’ALPS.
