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.
