SEALSQ Unaffected by New Tariffs: Semiconductor Exemption Ensures Continuity, Bolstered by Company's Innovation, U.S. Development Roadmap, and Post-Quantum Compliance

Geneva, Switzerland, April 04, 2025 (GLOBE NEWSWIRE) -- 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 confirmed that its operations are unaffected by the Trump administration's recently announced tariffs. An exemption on semiconductors under the current trade policy means the Company faces no impact at this stage, while its business is bolstered by the innovation strategy, U.S. development roadmap, and leadership in post-quantum cryptography—which is soon expected to become a legal compliance requirement under a U.S. executive order.

On April 2, 2025, the U.S. administration introduced its "Fair and Reciprocal Plan," setting a 10% tariff on most imports and higher rates on certain trading partners (e.g., 20% on China, 32% on Taiwan), effective April 5, 2025. However, semiconductors are currently exempt from these duties, safeguarding SEALSQ's portfolio of secure microchips used in IoT, automotive, healthcare, and infrastructure applications for the time being.

"The exemption on semiconductor tariffs keeps our business running smoothly," said Carlos Moreira, CEO of SEALSQ. "Our clients and partners can rely on uninterrupted access to our technology under the current policy."

SEALSQ's leadership extends to innovation.

SEALSQ's post-quantum semiconductor technology complies fully with the National Institute of Standards and Technology (NIST) standards, finalized in August 2024, safeguarding critical systems against quantum computing threats. This aligns with the January 2025 U.S. executive order making post-quantum cryptography mandatory for federal systems, reflecting long-term security as a legal compliance requirement. This positions SEALSQ as a potential partner for industries like defense, healthcare, and infrastructure, where we believe such standards are non-negotiable.

This mandate is driven by Executive Order 14119, "Strengthening and Promoting Innovation in the Nation's Cybersecurity," signed on January 15, 2025, and effective immediately. Issued in response to rising cyber threats, including quantum risks, it accelerates federal adoption of PQC following NIST's 2024 standards, building on earlier directives with a full transition deadline of 2035. It underscores the urgency of quantum-resistant cryptography for national security, a priority SEALSQ's technology already meets.

Looking ahead, SEALSQ plans to continue investing in U.S.-centric growth.

The company open a domestic Outsourced Semiconductor Personalization & Test center—programming chips with unique cryptographic keys—through strategic partnerships and alignment with initiatives like the CHIPS Act. "Localizing personalization in the U.S. strengthens our independence and security commitment," added Mr. Moreira. "It also ensures our post-quantum chips meet national priorities, delivering trust and efficiency to our clients."

With an optimized supply chain, cutting-edge post-quantum technology, and proactive U.S. development strategy, SEALSQ is ideally positioned to continue to provide seamless access to secure semiconductor solutions. As global trade dynamics unfold, the company remains a reliable, forward-thinking partner for its international and U.S. customers.
