SEALSQ Announces Majority Investment in Wecan Group and CHF 5 Million Strategic Commitment to Accelerate Post-Quantum AI Compliance Co-Pilot for Global Financial Institutions

Geneva, Switzerland, June 02, 2026 (GLOBE NEWSWIRE) —

Following an initial 28% equity stake acquired one year ago, SEALSQ increases its ownership in Wecan Group to a majority position, strengthening its ability to deliver secure, AI-powered compliance solutions and post-quantum financial infrastructure for the global financial industry

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, today announced that it has acquired a majority equity stake in Wecan Group, following an initial 28% investment made one year ago.

As part of this strategic transaction, SEALSQ will invest CHF 5 million to accelerate Wecan Group’s development and support the deployment of next-generation compliance Co-Pilote and post-quantum financial security solutions for the global financial industry.    The investment has been made using the Company’s Quantum Fund, SEALQUANTUM.com, an internal strategic investment initiative of SEALSQ using a dedicated allocation of our cash with the goal of accelerating the development of a fully integrated Quantum Vertical Sovereign Stack through investments in carefully selected quantum computing startups in the United States and Europe.

Wecan Group has established itself as a trusted technology provider for leading private banks and financial institutions, with clients including Pictet, Lombard Odier, Edmond de Rothschild, Syz and Barclays, among others. Wecan Group’s solutions are designed to help financial institutions streamline client data management, compliance workflows and lifecycle processes in a secure and collaborative environment.

Through this majority participation, SEALSQ and Wecan Group intend to accelerate the implementation of an AI-powered Compliance Copilot, built on a secure post-quantum infrastructure. The platform will integrate advanced Post-Quantum Cryptography (PQC) technologies, quantum-resistant Hardware Security Modules (HSMs), secure digital identity frameworks and blockchain-based trust mechanisms designed to protect sensitive financial and digital asset ecosystems against future quantum computing threats.

The objective is to provide financial institutions, wealth managers and fintech with a trusted platform capable of optimizing the processing of sensitive client information across the entire client lifecycle, from onboarding to periodic reviews, transaction monitoring, anti-money laundering (AML) and know-your-customer (KYC) compliance.

The initiative aims to further support the development of:

• Quantum-resistant authentication and transaction signing for digital banking
• Trusted AI governance and explainable compliance algorithms for regulated financial institutions
• Hardware Root of Trust and secure element technologies for financial applications
• Confidential AI and encrypted data processing leveraging homomorphic encryption and secure semiconductors
• Quantum-resilient digital identity systems for institutional and retail financial ecosystems

In addition, Wecan Group and SEALSQ plan to cooperate closely with SEALSQ’s parent company, WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY), a global leader in cybersecurity, digital identity and IoT, to integrate the WISeID digital identity ecosystem into financial services and digital asset platforms. This collaboration aims to provide financial institutions and cryptocurrency ecosystems with trusted, sovereign and post-quantum secure digital identity solutions enabling secure customer authentication, compliant onboarding, digital signatures, identity verification and trusted access management across banking, wealth management and blockchain applications.

The integration of WISeID technologies is intended to strengthen compliance and security capabilities by enabling:

• Post-quantum secure digital identity verification for financial clients
• Trusted electronic signatures and transaction authentication
• Secure identity wallets for banking and digital assets
• Sovereign identity frameworks aligned with global financial regulations
• Secure onboarding and KYC/AML identity validation
• Cross-border trusted digital identity interoperability for financial institutions and blockchain ecosystems
• Hardware-backed authentication leveraging SEALSQ secure semiconductors and WISeKey Root of Trust infrastructure

By combining Wecan Group’s compliance expertise, SEALSQ’s post-quantum semiconductor and cryptographic technologies, and WISeKey’s trusted digital identity infrastructure, the partnership aims to create one of the first integrated quantum-resilient trust platforms for the global financial and digital asset industries.

In private banking and financial services, client and transaction data represent some of the most sensitive and strategically important information managed by institutions. Combining post-quantum security with AI-driven optimization of compliance is increasingly becoming a critical requirement in light of rising cybersecurity threats, the emergence of quantum computing risks, evolving regulatory expectations around algorithms and data governance, and the accelerated institutional adoption of tokenized finance.

Carlos Moreira, CEO of SEALSQ commented: “Our majority investment in Wecan Group represents a significant step in SEALSQ’s strategy to bring post-quantum security to the most sensitive sectors of the global economy. Financial institutions and digital asset platforms are entering a new era in which cybersecurity, compliance automation, digital identity and trusted AI must converge. At the same time, cryptocurrencies and blockchain infrastructures must evolve toward quantum resilience to preserve long-term trust and security. By combining SEALSQ’s post-quantum technologies, Wecan Group’s expertise in private banking compliance infrastructure and WISeKey’s trusted digital identity ecosystem, we aim to deliver a secure and scalable trust platform for the financial industry and the digital asset economy worldwide.”

Vincent Pignon, Founder and CEO of Wecan Group added: “Wecan Group was created to help financial institutions manage trust, compliance and sensitive client information more efficiently. With SEALSQ as a majority shareholder and strategic technology partner, we are entering a new phase of growth. This investment will allow us to accelerate the deployment of our Compliance Management Copilot and strengthen our infrastructure with post-quantum security capabilities, providing banks and financial institutions with future-ready solutions for client lifecycle.”

The transaction reinforces SEALSQ’s positioning at the intersection of post-quantum cybersecurity, digital identity, trusted AI, blockchain security and regulated financial infrastructure, and supports its ambition to address the most demanding security, compliance and digital asset protection needs of global financial institutions and the emerging tokenized economy.
