SEALSQ Corp reported preliminary unaudited revenue of $16.3 million for the first nine months of 2026. This figure marks a 65% increase from the $9.9 million reported during the same period in 2025. Growth was driven by strong demand for Vault-IC secure-element products and expanded PKI services. The company’s IC'ALPS subsidiary also contributed to the revenue gains.
Management reaffirmed full-year 2026 revenue guidance of $27 million to $36 million. This target represents a 50% to 100% increase over 2025 audited revenue. Based on year-to-date results, SEALSQ projects fourth-quarter revenue will range between $11 million and $20 million.
Key product milestones included achieving NIST FIPS 140-3 Level 3 validation for the VaultIC408.
