WISeKey Reports Audited FY2025 Revenue of $19.3M; SEALSQ Revenue Up 66%

What happened

WISeKey, parent of SEALSQ Corp, reported audited FY2025 revenue of $19.3 million, a 62% year-over-year increase, with subsidiary SEALSQ posting 66% growth. The company reaffirmed FY2026 guidance of 50%-100% revenue growth and disclosed an unaudited Q1 2026 revenue of $4.2 million. Management highlighted a commercial pipeline exceeding $200 million for SEALSQ through 2029, including over $60 million linked to QS7001 and QVault TPM programs. However, cash at the parent level of over $535 million contrasts with SEALSQ's last reported cash of $84.6 million at year-end 2024, raising questions about intra-group liquidity. The results slightly exceed earlier preliminary guidance but still rely on legacy and IC'ALPS services for growth, with no clear attribution of PQC shipments yet.

Implication

For short-term investors, the confirmed FY2025 revenue and reiterated 50%-100% growth guidance support the bullish narrative, but the lack of PQC revenue breakdown and the cash discrepancy between parent and subsidiary warrant caution. The reaffirmed pipeline is encouraging, but without signed production awards or long-term contracts, the conversion risk remains high. The company's reliance on convertible debt and equity-linked financing could lead to dilution if the stock price weakens, particularly given the VWAP-linked conversion terms. The next critical milestone is the Q1 2026 detailed report, which should clarify whether growth is driven by PQC or legacy products. Overall, the risk-reward is still skewed to the downside until tangible PQC order conversions are visible.

Thesis delta

The audited FY2025 revenue of $19.3M is slightly above the prior preliminary $18M, but the cash position and pipeline claims still lack SEC filing-level reconciliation. The thesis shifts from 'waiting for audited results' to 'monitoring product mix and order conversion'—the fundamental wait-and-see stance remains unchanged, as the core uncertainties of TPM timing and dilution persist. No material upgrade or downgrade is warranted; the stock remains a WAIT at current levels given the limited operational evidence of a self-funding PQC ramp.
