---	---
●	Expected<br> continued expansion of Vault-IC secure element sales into connected devices, industrial systems<br> and edge-computing applications.
---	---
●	Anticipated<br> revenue contributions from Quantix Edge Security, a €40 million joint venture with the<br> Spanish government to establish a Post-Quantum sovereign semiconductor personalization center<br> in Murcia, Spain, as the project ramps-up through H2 2026.
---	---
●	Expected<br> execution of a custom post-quantum ASIC design contract in H2 2026, which is expected to<br> generate an additional revenue stream beginning in H2 2026.
---	---
●	Growing<br> commercial traction from more than fifteen prospective customers and partners actively evaluating<br> QS7001 and its SDK, supported by partnerships with Lattice Semiconductor in the U.S. market.
---	---

Carlos Moreira, CEO of SEALSQ noted, “The first half of 2026 was an important inflection point for SEALSQ. We delivered approximately 120% year-over-year revenue growth, completed the acquisition of Miraex SA to add quantum photonics interconnect capabilities, increased our ownership in Wecan Group to a majority position, and participated as a lead investor in Quobly’s €115 million Series A round alongside STMicroelectronics. Together, these steps strengthen our position as a vertically integrated, sovereign-focused post-quantum security and quantum technology company, from silicon-level roots-of-trust through to quantum compute and orbital delivery. With QS7001 advancing through its final certification milestones, and a growing commercial pipeline, we believe we have the capital, technology and ecosystem required to lead in the post-quantum era.”

John O’Hara, CFO of SEALSQ added, “The first half of 2026 demonstrates continued progress in our financial fundamentals. Preliminary H1 2026 revenue of approximately $11 million, more than double the $5 million revenue in H1 2025, reflects a healthy step-up from roughly $4 million revenue in Q1 to about $7 million revenue in Q2 as IC’ALPS, Vault-IC secure elements, PKI services and the Quantix Edge Security project all contributed. Our cash and short-term investments of approximately $495 million as of June 30, 2026, which were boosted by the $125.0 million Registered Direct Offering completed in March 2026, provides significant capacity to fund growth and execute on our priorities without compromising financial discipline. With an active pipeline of more than $225 million through 2029, including over $60 million tied to QS7001 and QVault TPM, and a reaffirmed FY 2026 revenue guidance range of $27 million to $36 million, we believe we have both the resources and visibility needed to support our commercial ramp and deliver on our financial objectives.”

Post-quantumproduct and certification progress

SEALSQ’s post-quantum semiconductor portfolio is anchored by two primary products:

●	QS7001<br> Post-Quantum Secure Element, designed to embed NIST-standardized algorithms and hybrid cryptographic<br> capabilities at the silicon level.
●	QVault<br> Trusted Platform Module (TPM), designed to provide a post-quantum-capable hardware root-of-trust<br> for systems adopting hybrid and crypto-agile architectures.
---	---

In H1 2026, SEALSQ achieved key milestones that support commercialization:

●	QS7001<br> obtained NIST SP 800-90B Entropy Source Validation (ESV Certificate #E333), which is a mandatory<br> prerequisite for achieving FIPS 140-3 Level 3 and CC EAL5+ certifications.
●	In<br> March 2026, QS7001 successfully completed Common Criteria fault-injection and side-channel<br> resistance tests. The Company expects to receive CC EAL5+ Evaluation Technical Report (ETR)<br> from the Information Technology Security Evaluation Facility (ITSEF) lab in H2 2026.
---	---
●	QVault<br> TPM customer sampling progressed, and SEALSQ expects initial commercial revenues from this<br> product by the end of H2 2026.
---	---
●	QS7001<br> evaluation kits, available since November 2025, continue to be deployed into enterprise customer<br> environments, supporting a 12–18 month sales and integration cycle that is expected<br> to underpin late-2026 and 2027 production revenues.
---	---

These certifications and evaluations are critical for customers operating under stringent regulatory regimes, and they position SEALSQ’s products to serve markets where independent validation and certification are a prerequisite for procurement.

Jean-Pierre Enguent, CTO of SEALSQ, added, “The convergence of AI and post-quantum technologies is driving one of the most significant shifts in semiconductor security architecture since the introduction of the TPM standard. Our QS7001 post-quantum secure element, which has achieved NIST SP 800-90B Entropy Source Validation and passed all key Common Criteria fault-injection and side-channel tests, is designed to be one of the most comprehensively certified post-quantum silicon platforms available. This gives customers a high level of assurance at a time when regulators are beginning to mandate the transition to post-quantum cryptography under CNSA 2.0, NIST FIPS standards and the EU Cyber Resilience Act.”

Regulatoryand market backdrop

Global regulators and standards bodies are moving forward with post-quantum cryptography adoption, creating a supportive backdrop for SEALSQ’s offerings:

●	NIST<br> has finalized initial post-quantum standards and is progressing with CNSA 2.0, which guides<br> U.S. federal agencies in transitioning to quantum-resistant algorithms.
●	The<br> European Commission and national agencies are establishing deadlines for migration to post-quantum<br> cryptography across critical infrastructure, with some regulators requiring crypto-agile<br> architectures in newly deployed systems.
---	---
●	ANSSI,<br> the French national cybersecurity agency, has indicated that it will cease certifying non–quantum-resistant<br> security products within a defined timeframe, further accelerating the need for compliant,<br> post-quantum-ready solutions.
---	---
