SEALSQ Moves to Acquire Quantum Processor Developer Quobly in Potential $200 Million Deal
Geneva, Wednesday, 14 January 2026.
SEALSQ enters exclusive negotiations to acquire French firm Quobly for approximately $200 million, aiming to embed security directly into silicon-based quantum processors for a sovereign European infrastructure.
Structuring the Strategic Acquisition
On January 14, 2026, SEALSQ Corp (NASDAQ: LAES) formalized its intent to expand its footprint in the quantum computing sector by signing a non-binding Memorandum of Understanding (MoU) with Quobly SAS [1][3]. The agreement outlines a multi-stage transaction structure where SEALSQ aims to first secure a minority interest in the Grenoble-based firm, followed by a potential acquisition of a majority stake [2][4]. If realized, the total investment is projected to reach approximately $200 million, a move anchored by SEALSQ’s dedicated Quantum Fund [3][4]. This development follows an initial strategic collaboration between the two entities that was previously announced on November 21, 2025 [1][4].
Strategic Alignment and Technological Synergy
The proposed acquisition is designed to integrate security directly into the hardware layer of quantum computing. Carlos Moreira, the Founder and CEO of SEALSQ, emphasized that as quantum computing evolves into a strategic infrastructure, security must be embedded “from day one” [1][2]. By combining Quobly’s CMOS-compatible quantum technology with SEALSQ’s post-quantum Root-of-Trust capabilities, the companies aim to create a platform for building sovereign and trusted quantum systems specifically designed for the European market [2][4]. This integration is intended to address the complexities of post-quantum cryptography by leveraging SEALSQ’s existing semiconductor expertise [2].
Quobly’s Industrial Trajectory
Founded in 2022 and leveraging 15 years of research from CEA-Leti and CNRS, Quobly has positioned itself as a pioneer in silicon-based quantum processing [2][4]. The company has successfully attracted significant capital in recent years to support its technological roadmap. Quobly raised €19 million in seed funding in 2023, followed by an additional €21 million in 2025 to advance its Q100T program [2][4]. Maud Vinet, Quobly’s Co-Founder and CEO, noted that joining forces with a post-quantum security leader would accelerate the company’s industrial journey and international expansion [1][4].
Market Reaction and Financial Context
Following the announcement, market reactions for the related entities showed distinct volatility. Shares of SEALSQ’s parent company, WISeKey International Holding (NASDAQ: WKEY), experienced a decline of 7.61% immediately following the news [4]. In contrast, SEALSQ (NASDAQ: LAES) has maintained a stronger technical position recently; prior to the announcement, the stock closed at $4.31. This price point indicates the stock is trading approximately 13.123% above its 200-day moving average of $3.81 [3]. The transaction remains subject to the execution of definitive agreements, due diligence, and necessary regulatory approvals before it can be finalized [1][3].
