SEALSQ, a WISeKey Affiliate, and WeCanGroup Sign Strategic Agreement for SEALSQ to Acquire a 30% Stake in WeCanGroup

Geneva, Switzerland, March 24, 2025 -- SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"),

a subsidiary of WISeKey, and WeCanGroup SA have entered into a strategic agreement under which SEALSQ will acquire a 30% equity stake in WeCanGroup. This collaboration aims to accelerate the adoption of blockchain-based security solutions within the Web 3.0 ecosystem, with a strong focus on post-quantum cryptography, Internet of Things (IoT) security, and financial sector resilience against emerging cyber threats.

Advancing Post-Quantum Security in the Financial Sector and IoT

As quantum computing advances, traditional cryptographic methods face increasing vulnerabilities, threatening critical infrastructure across industries. In response, SEALSQ, WISeKey, and WeCanGroup will integrate their Web 3.0 and post-quantum cryptographic technologies to develop advanced Know Your Customer (KYC), Know Your Business (KYB) and Know Your Object (KYO) solutions. These solutions will be embedded into SEALSQ’s post-quantum semiconductors, ensuring long-term cybersecurity resilience in both financial sectors and IoT.

Strengthening the Financial Sector Against Quantum Threats

With the financial sector heavily reliant on digital identity verification, secure transactions, and compliance processes, the adoption of quantum-resistant cryptographic solutions is essential to maintaining trust and regulatory compliance. Through this partnership:

• WeCanGroup’s blockchain-based financial compliance solutions will integrate SEALSQ’s post-quantum encryption to secure digital transactions, protecting banks, wealth managers, and financial institutions from future quantum-based cyber threats.
• KYC, KYB and KYO innovations will enhance digital identity verification, reducing fraud risks in banking, digital asset management, and decentralized finance (DeFi).
• WeCan Comply, a platform for orchestrating KYC & KYB compliance data, co-created with leading private banks and External Asset Managers, will be reinforced with quantum-resistant digital signatures and blockchain-backed compliance records, ensuring long-term data security.

IoT Security in the Post-Quantum Era

The exponential growth of IoT devices has introduced new cybersecurity challenges, as billions of connected devices now transmit and store sensitive data. By embedding post-quantum cryptographic algorithms directly into SEALSQ’s secure semiconductors, this partnership will:

• Protect IoT ecosystems from quantum-enabled attacks by ensuring device authentication, secure boot processes, and encrypted communications.
• Enable quantum-safe identity management for IoT devices, ensuring data integrity and trust across smart cities, autonomous vehicles, healthcare IoT, and industrial automation.
• Strengthen supply chain security by ensuring the authenticity and traceability of IoT devices throughout their lifecycle using blockchain-backed authentication.

Enhancing Web 3.0 with Post-Quantum Trust and Compliance

By combining SEALSQ’s post-quantum secure semiconductors with WeCanGroup’s blockchain-based compliance and tokenization solutions, this partnership will set new standards for trust and security in Web 3.0 ecosystems. The integration of these technologies will provide:

• Decentralized Identity Management (DID): Enabling users and enterprises to control their digital identities securely in a post-quantum environment.
• Secure Tokenization of Financial Assets: Enhancing asset management security through blockchain-based authentication and quantum-resistant encryption.
• Regulatory Compliance Automation: Ensuring long-term protection of financial records, digital assets, and smart contracts against quantum-enabled cyber threats.
