SEALSQ Revenue Jumps 131% as H1 2026 Loss Widens
SEALSQ announced its first-half 2026 revenue reached $11.2 million, a 131% increase from $4.8 million in the same period last year, according to results published September 11. Despite this revenue growth, the company’s net loss widened to $27.8 million, up from a $20.0 million loss in H1 2025. This indicates that though revenue climbed, the business remains unprofitable, with a significant portion of its growth attributed to an acquisition rather than sales of its post-quantum chips.
SEALSQ’s H1 2026 Performance
SEALSQ specializes in post-quantum semiconductor, PKI, and trusted provisioning products. For the six months ending June 30, 2026, gross profit surged by 233% to $5.4 million, achieving a gross margin of approximately 48%, as detailed in the company’s release. Cash, cash equivalents, and restricted cash totaled $486.1 million at the close of the period.
The company attributes its revenue increase to renewed demand for its Vault-IC secure elements, growth in PKI subscriptions, initial revenue from its Murcia, Spain design center, and six months of consolidated revenue from IC’Alps SAS.
The acquisition of IC’Alps in August 2025 contributed approximately $2.5 million during the half, meaning a substantial portion of the reported growth resulted from this acquisition rather than organic sales of SEALSQ’s core products.
Financial Details Behind the Growth
Operating loss expanded to $32.2 million, up from $21.2 million, according to the 6-K filing summary. Research and development (R&D) spending increased to $8.7 million, and general and administrative costs climbed to $23.1 million, which the company attributes to acquisition integration and corporate expansion.
Though higher interest income from its cash reserves partially offset these expenses, the company’s expenditures significantly outpaced its earnings.
Geographically, North America accounted for 50% of revenue, EMEA for 33%, and Asia Pacific for 17%. SEALSQ reiterated its FY2026 revenue guidance of $27 million to $36 million, projecting 50% to 100% growth over its audited FY2025 revenue of $18.3 million.
Unproven Aspects and Future Outlook
Regarding product development, SEALSQ announced that its QS7001 chip achieved NIST SP 800-90B Entropy Source Validation, which pertains to a randomness source but does not, by itself, make a system quantum-resistant.
The company reported that 30 prospective customers were evaluating its QVault TPM and QS7001, with engineering samples available by period end. These are currently prospects and samples, not indicators of shipping volume. Initial commercial revenue from these products is anticipated in late H2 2026, according to the release.
SEALSQ also highlighted strategic investments, including a stake in EeroQ’s electrons-on-helium quantum computing research and a lead investor role in Quobly’s EUR115 million Series A funding round.
These represent investments in early-stage prototypes, distinct from SEALSQ’s direct revenue generation. Similar full-stack ambitions are emerging across the sector, exemplified by IonQ’s planned acquisition of SkyWater Technology and the broader policy context of the proposed EU Quantum Act.
SEALSQ’s projected pipeline of “more than $225 million through 2029” is a management estimate, subject to conversion and customer validation, and does not represent booked revenue. The company did not disclose customer concentration, the share of recurring revenue, or whether its post-quantum products utilize NIST-standardized schemes.
