SEALSQ (NASDAQ: LAES) eyes $200M majority stake in quantum firm Quobly
Rhea-AI Filing Summary
SEALSQ Corp reported that it has signed a non-binding Memorandum of Understanding to enter exclusive negotiations for a strategic investment in French quantum computing firm Quobly. The contemplated multi-stage deal would start with a minority stake and could lead to SEALSQ acquiring a majority interest in Quobly, with a potential total investment of approximately $200M, all subject to definitive agreements, due diligence, approvals, and customary conditions.
Quobly develops silicon-based quantum processors using established semiconductor manufacturing processes, and already works with SEALSQ under an existing collaboration. The proposed transaction fits within SEALSQ’s quantum strategy and its dedicated Quantum Fund, aiming to build secure-by-design, post-quantum-ready computing platforms for sectors such as defense, intelligence, financial services, and pharmaceuticals.

SEALSQ enters exclusive talks on a potential $200M majority stake in quantum startup Quobly.
SEALSQ has signed a non-binding Memorandum of Understanding for exclusive negotiations to make an initial minority investment and potentially acquire a majority stake in Quobly, with a contemplated total investment of about
Strategically, the move extends SEALSQ’s post-quantum cryptography and semiconductor focus into silicon-based quantum processors, leveraging Quobly’s CMOS-compatible technology. It also ties into SEALSQ’s dedicated Quantum Fund and an existing collaboration between the two companies, aiming to create secure-by-design quantum systems for mission-critical sectors.
Because the understanding is non-binding and the transaction may not be completed, the ultimate financial and operational impact is uncertain based on the current disclosure. Future updates, if any, would likely clarify deal terms, ownership levels at each stage, and how Quobly’s technology could be integrated into SEALSQ’s product roadmap.

SEALSQ Announces Entry into a Memorandum of Understanding Regarding a Potential Strategic Investment and Acquisition of Quantum Computing Firm Quobly
Quobly is a pioneer in quantum microelectronics, developing silicon-based quantum processors using proven semiconductor manufacturing processes
Geneva, Switzerland, January 14, 2026 -- SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a global leader
in semiconductors security and Post-Quantum Cryptography (PQC) solutions, today announced that it has entered
into a non-binding Memorandum of Understanding leading to exclusive negotiations with the shareholders of Quobly SAS, a leading French
technology company pioneering the development of silicon-based quantum computers (“QUOBLY”), to make an initial minority investment
and then potentially acquire a majority stake in QUOBLY. The proposed transaction remains subject to the negotiation and execution of
definitive agreements, completion of financial, legal, technical and commercial due diligence, receipt of required corporate and regulatory
approvals, and the satisfaction of other customary closing conditions.
These exclusive negotiations result from the execution of a non-binding Memorandum of Understanding that contemplates a multi-stage transaction.
This transaction is anchored within SEALSQ’s Quantum strategy and supported in part by its dedicated Quantum Fund designed to accelerate the emergence of sovereign, secure, and industrial-scale quantum technologies across Europe. If completed, the transaction would result in a total investment of approximately $200M by SEALSQ in return for a majority stake in QUOBLY.
The entering into exclusive negotiations with QUOBLY follows the ongoing strategic collaboration between SEALSQ and QUOBLY, announced on November 21, 2025. The collaboration as proposed to be expanded, plans to deliver accelerated benefits, including joint leadership in trustworthy and industrialized quantum computers and enhance EU and US market expansion.
SEALSQ and QUOBLY aim to establish a reference platform for secure-by-design quantum computing to define how quantum-resistant security can be embedded directly into future quantum infrastructures serving defense, intelligence, financial services, pharmaceuticals, and other mission-critical sectors.
Maud Vinet, Co-Founder and Chief Executive Officer of QUOBLY, commented: “This proposed transaction by SEALSQ marks an important step in QUOBLY’s industrial journey. Joining forces with a global leader in post-quantum security and semiconductor expert accelerates our ability to bring secure, scalable silicon-based quantum processors to market, and to expand internationally while consolidating our technological roadmap.”
Carlos Moreira, Founder and Chief Executive Officer of SEALSQ, stated: “The proposed acquisition of QUOBLY is fully aligned with our Quantum roadmap. As quantum computing becomes a strategic infrastructure, security must be embedded at the hardware level from day one. QUOBLY’s CMOS-compatible quantum technology, combined with SEALSQ’s post-quantum Root-of-Trust capabilities, creates a unique platform to build sovereign, trusted, and industrialized quantum systems for Europe, and their strategic partners.”
