SEALSQ Corp reported strong preliminary unaudited results for the first half of 2026, with H1 2026 revenue of about $11 million versus $5 million in H1 2025, an increase of roughly 120%. Q2 2026 preliminary revenue was about $7 million, up from $4 million in Q1 2026, showing sequential growth.
As of June 30, 2026, cash and short-term investments were approximately $495 million, giving the company substantial liquidity. Growth was driven mainly by higher demand for its Vault-IC secure element products, a larger contribution from IC’ALPS SAS, and expanding PKI subscription and Quantix Edge Security revenues.
The company also advanced post-quantum security, with its QS7001 Post-Quantum Secure Element obtaining NIST SP 800-90B Entropy Source Validation and completing key Common Criteria security tests. Through its SEALQuantum Fund, SEALSQ targets a $200 million internal allocation and has already committed over $60 million to strategic technology investments.
SEALSQ Corp reported preliminary unaudited H1 2026 revenue of approximately $11 million, up about 120% from H1 2025, driven mainly by its Vault-IC secure element products, IC’ALPS consolidation, PKI subscriptions and initial Quantix Edge Security revenue.
The company reaffirmed its FY 2026 revenue guidance of $27 million to $36 million, representing 50%–100% year-over-year growth versus audited FY 2025 revenue of $18.3 million. Management highlighted a step-up from roughly $4 million in Q1 2026 revenue to about $7 million in Q2.

SEALSQ Corp filed a Form 6-K highlighting that Quantisimo Corp, its quantum-focused special purpose vehicle jointly created with WISeKey, has signed a non-binding Letter of Intent with SPAC GigCapital8 to pursue a Nasdaq listing. The contemplated business combination implies an expected pre-money enterprise value of about $575 million, with an ambition to reach $2 billion through additional acquisitions of up to five quantum companies. Closing is currently targeted for the first quarter of 2027 and would remain subject to definitive agreements, shareholder and regulatory approvals, financing, and other customary conditions, with no assurance the transaction will be completed.
SEALSQ Corp, through its joint venture Quantisimo, entered into a non-binding letter of intent for a business combination with SPAC GigCapital8. The contemplated deal would create a publicly traded platform focused on trusted quantum infrastructure, with the combined company expected to have a pre-money enterprise value of about $575 million.
The parties envision growing this platform via consolidated acquisitions of up to five additional quantum companies, and the transaction is currently expected to close in the first quarter of 2027. SEALSQ is expected to contribute selected quantum-focused assets, technologies, and intellectual property to Quantisimo, but the transaction is subject to due diligence, definitive agreements, regulatory and shareholder approvals, financing, and other closing conditions, and may not be completed.

To satisfy tax obligations from the exercise, 96,530 ordinary shares were disposed of as a tax-withholding transaction at a fair market value of $3.07 per share. After these transactions, Ward holds 270,531 ordinary shares directly, and no remaining derivative position from the exercised option awards is shown in this filing.
SEALSQ Corp filed a Form 6-K highlighting its role as a lead investor in Quobly’s €115 million Series A financing, made through the SEALSQ Quantum Fund. The round is led by STMicroelectronics, SEALSQ, Isalt and the French Public Investment Bank.
The SEALSQ Quantum Fund, launched in February 2025, has grown from a $20 million initial allocation to $200 million. Excluding the new Quobly deal, it has deployed about $30 million across several quantum and security-focused companies. As part of this investment, SEALSQ CEO Carlos Moreira will join Quobly’s board, supporting SEALSQ’s Quantum Vertical Sovereign Stack strategy.
SEALSQ Corp has completed a strategic minority investment in French quantum computing company Quobly SAS. Under a Series A Investment Agreement, SEALSQ subscribed for Series A preferred shares with attached broad-based anti-dilution ratchet warrants for a total of EUR 14,999,400, subject to conditions precedent that were satisfied before closing on June 2, 2026.
The ratchet warrants allow an adjustment of SEALSQ’s subscription price to match the average price of future Quobly share issuances over four years if they are sold below the original Series A price. SEALSQ and two other investors each obtained the right to appoint one member to Quobly’s supervisory board, and SEALSQ appointed its CEO, Carlos Moreira. Any two investor board members can jointly veto key corporate actions such as bylaw changes, mergers, major reorganizations, or new securities issuances.
