SEALSQ and Quobly Mutually Agree to Halt Discussions Regarding a Potential Majority Investment or Acquisition by SEALSQ
Geneva, Switzerland, February 20, 2026 -- SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that
focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, and
Quobly, today announced that they have mutually agreed to halt discussions regarding a potential majority investment or acquisition of
Quobly by SEALSQ.
The parties will instead explore the possibility of a minority investment, to be discussed once Quobly launches its Series A financing round.
This decision reflects a shared preference for a minority investment structure that is more compatible with the current pace of quantum computing investments in France.
The companies will continue their technical and industrial collaboration announced in Nov. 2025 https://www.sealsq.com/investors/news-releases/sealsq-and-quobly-announce-collaboration-to-advance-secure-and-
scalable-quantum-technologies, particularly around the convergence of secure semiconductor technologies and scalable quantum architectures.
