SEALSQ Corp halts majority investment talks with Quobly

SEALSQ Corp and Quobly mutually agreed to halt discussions over a potential majority investment or acquisition by SEALSQ and opted instead to pursue a minority investment to be addressed when Quobly launched its Series A financing; the companies framed the choice as more compatible with the current pace of quantum computing investments in France.

SEALSQ focuses on developing and selling Semiconductors, Public Key Infrastructure (PKI), and Post-Quantum technology hardware and software products, and the companies intended to maintain their technical and industrial collaboration announced in Nov. 2025 rather than proceed with a majority transaction.

The PR described work at the intersection of secure semiconductor technologies and scalable quantum architectures, and it noted SEALSQ’s integration of Semiconductors, PKI, and Provisioning Services with an emphasis on Quantum Resistant Cryptography; the release also stated that traditional cryptographic methods such as Runtime Security Agent (RSA) and Elliptic Curve Cryptography (ECC) were increasingly vulnerable and that Post-Quantum Cryptography (PQC) would be embedded into semiconductor solutions for applications listed in the release.

The parties planned to continue the technical and industrial collaboration announced in Nov. 2025, particularly around the convergence of secure semiconductor technologies and scalable quantum architectures, and they planned to discuss a minority investment once Quobly opened its Series A financing round.

The communication contained forward-looking statements about business strategy, financial performance, completion of contemplated minority investments, market data, future events or developments, and factors that could cause actual results to differ materially, and it referenced risks described in SEALSQ’s filings with the Scope 1–3 Emission Calculator (SEC).
