SEALSQ Corp Reports Revenue Up 120% in Preliminary H1 2026 Results

Insider BriefPRESS RELEASE — 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 its preliminary unaudited financial results for the six-month period ended June 30, 2026 (“H1 2026”). The Company also provided an update on key strategic initiatives and reaffirmed its full-year 2026 revenue guidance. All figures are preliminary and unaudited.The 120% year-over-year revenue increase in H1 2026 was driven primarily by the strong growth in the demand for our Vault-IC secure element product family. In addition, H1 2026 included six months of consolidated revenues from IC’ALPS SAS, which was acquired in August 2025. Additional contributions came from continued growth in PKI subscription contracts as customers expand digital identity and certificate deployments, and initial revenues from the Quantix Edge Security semiconductor design center in Murcia, Spain.While SEALSQ plans to provide more detailed segment disclosures with its full H1 2026 report, preliminary trends indicate solid performance across several areas:SEALSQ‘s outlook statements are based on current expectations. The following statements are forward-looking and actual results could differ materially depending on market conditions and the factors set forth under “Forward Looking Statements” below.SEALSQ reaffirmed its previously communicated FY 2026 revenue guidance, with revenue expected to grow between 50% and 100% year-over-year relative to audited FY 2025 revenue of $18.3 million.The Company’s FY 2026 guidance is supported by several identifiable revenue drivers: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.”SEALSQ’s post-quantum semiconductor portfolio is anchored by two primary products:In H1 2026, SEALSQ achieved key milestones that support commercialization: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.”Global regulators and standards bodies are moving forward with post-quantum cryptography adoption, creating a supportive backdrop for SEALSQ’s offerings:SEALSQ’s focus on hardware roots-of-trust, European presence and alignment with these frameworks is intended to support customer adoption and long-term demand.The SEALQuantum Fund, which is an internal strategic initiative through which SEALSQ allocates its own capital to accelerate development of its post-quantum and quantum technology capabilities, has a target allocation of $200 million, underpinning SEALSQ’s long-term Root-to-Qubit strategy with the goal of accelerating the development of a fully integrated Quantum Vertical Sovereign Stack. The initiative focuses on three domains:To date, over $60 million has been allocated into strategic transactions, including IC’ALPS, Miraex, Quobly, Quantix Edge Security, ColibriTD, EeroQ, WISeSat, Quantix Edge Security and Wecan Group.During H1 2026, SEALSQ advanced a series of strategic, operational and product initiatives intended to strengthen its position in post-quantum semiconductors, trusted infrastructure and sovereign quantum technologies. These transactions provide SEALSQ with strategic collaboration opportunities and operational capabilities across multiple layers of the emerging quantum ecosystem.Collectively, these actions are intended to position SEALSQ as a vertically integrated participant in both post-quantum security and quantum computing markets.TopicsShare Get the latest research, company news, and market intelligence every week.
