Watch Q4 2026 revenue print against the $11M-$20M guidance range — the wide spread reflects conversion risk on post-quantum pipeline. Monitor customer qualification milestones for QVault TPM and QS7001, as material post-quantum revenue is not expected until 2027.
Price Chart
Executive Summary
SEALSQ Corp reported preliminary 9M 2026 revenue of $16.3 million, up 65% YoY from $9.9 million, and reaffirmed FY 2026 revenue guidance of $27M-$36M (50-100% growth). Cash stood at ~$463 million. The filing also highlighted VaultIC408 achieving NIST FIPS 140-3 Level 3 validation and a post-quantum pipeline of >$200 million through 2029. While the revenue growth is strong, the implied Q4 range ($11M-$20M) is wide and the post-quantum revenue contribution is pushed to 2027+, tempering near-term conviction.
