SEALSQ enters a non-binding MoU to invest in and potentially acquire a majority stake in silicon-spin-qubit firm Quobly (~$200M)
On 2026-01-14 SEALSQ (Nasdaq: LAES) announced a non-binding Memorandum of Understanding, opening exclusive negotiations with the shareholders of Quobly SAS - a Grenoble-based silicon-based quantum-computing developer (CEA-Leti / CNRS heritage) - to make an initial minority investment and then potentially acquire a majority stake, a transaction that if completed would total approximately $200 million, supported in part by SEALSQ's dedicated Quantum Fund. The MoU is non-binding and subject to definitive agreements, due diligence and regulatory approvals. This formalizes the companies' 2025-11-21 collaboration into an acquisition track.
A ~$200M intended majority investment moves SEALSQ from a security-and-chip vendor toward owning a CMOS-compatible silicon-spin-qubit hardware platform, a notable vertical step for a PQC company; the non-binding MoU status holds it in the mid band pending definitive terms.
If consummated, SEALSQ would pair post-quantum security with a European foundry-compatible qubit roadmap, a sovereign-stack play; this MoU is the precursor to SEALSQ's later lead role in Quobly's 2026 Series A.
