Geneva, Switzerland, July 06, 2026 (GLOBE NEWSWIRE) -- Preliminary H1 2026 revenue of approximately $11 million, increased 120% vs. H1 2025, underscoring strong operating momentum. Supported by approximately $495 million in cash and short-term investments, and an active pipeline exceeding $225 million through 2029, the Company reiterates its expectations of 50%–100% revenue growth in FY 2026. 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. H1 2026 preliminary financial highlights Preliminary unaudited H1 2026 revenue is approximately $11 million, compared to revenue of $5 million in H1 2025, representing approximately 120% year-over-year growth. Q2 2026 preliminary revenue of approximately $7 million reflects a sequential acceleration from the $4 million revenue recorded in Q1 2026. As of June 30, 2026, cash and short-term investments stand at approximately $495 million, providing substantial liquidity to fund organic growth and strategic investments. The Company’s active business pipeline of more than $225 million in potential revenue opportunities through 2029, includes more than $60 million directly tied to QS7001 and QVault TPM post-quantum products. These figures reflect management estimates and are subject to risks such as conversion risks, customer validation, and technical integration. The Company continued to advance its strategic partnerships with the completion of its participation in Quobly’s Series A financing as well as two further investments in EeroQ, thereby strengthening the SEALQuantum initiative. 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 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. Revenue mix and business driversWhile SEALSQ plans to provide more detailed segment disclosures with its full H1 2026 report, preliminary trends indicate solid performance across several areas: Secure elements (Vault-IC) continued to benefit from connected-device demand, particularly in industrial and IoT use cases where hardware roots-of-trust are increasingly mandated by customers and regulators. PKI and trust services showed recurring revenue growth, reflecting higher volumes of digital identity issuance, certificate renewals and subscription contracts, supported by evolving cyber and data-protection regulations. The consolidation of IC’ALPS revenue contributed meaningfully to H1 2026 performance, validating the acquisition strategy and providing SEALSQ with enhanced ASIC design and manufacturing capabilities. Early revenue from Quantix Edge Security demonstrates traction for sovereign semiconductor initiatives and positions SEALSQ to participate in regional programs focused on secure, domestically controlled chip design and personalization. FY 2026 guidance and growth outlook 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: Increasing PKI recurring revenues as customers respond to escalating cyber threats and the enforcement of regulatory frameworks such as the EU Cyber Resilience Act, enhancing overall revenue visibility. Full-year consolidation of IC’ALPS SAS revenues, compared to five months of contribution in FY 2025, together with an expanding ASIC design contract pipeline expected to support continued top-line growth. Initial revenues from the QS7001 and QVault TPM post-quantum platforms are expected to commence towards the end of H2 2026 following the completion of technical validation and early customer integration cycles. Expected continued expansion of Vault-IC secure element sales into connected devices, industrial systems and edge-computing applications. Anticipated revenue contributions from Quantix Edge Security, a €40 million joint venture with the Spanish government to establish a Post-Quantum sovereign semiconductor personalization center in Murcia, Spain, as the project ramps-up through H2 2026. Expected execution of a custom post-quantum ASIC design contract in H2 2026, which is expected to generate an additional revenue stream beginning in H2 2026. Growing commercial traction from more than fifteen prospective customers and partners actively evaluating 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-quantum product and certification progressSEALSQ’s post-quantum semiconductor portfolio is anchored by two primary products: QS7001 Post-Quantum Secure Element, designed to embed NIST-standardized algorithms and hybrid cryptographic capabilities at the silicon level. QVault Trusted Platform Module (TPM), designed to provide a post-quantum-capable hardware root-of-trust for systems adopting hybrid and crypto-agile architectures. In H1 2026, SEALSQ achieved key milestones that support commercialization: QS7001 obtained NIST SP 800-90B Entropy Source Validation (ESV Certificate #E333), which is a mandatory prerequisite for achieving FIPS 140-3 Level 3 and CC EAL5+ certifications. In March 2026, QS7001 successfully completed Common Criteria fault-injection and side-channel resistance tests. The Company expects to receive CC EAL5+ Evaluation Technical Report (ETR) from the Information Technology Security Evaluation Facility (ITSEF) lab in H2 2026. QVault TPM customer sampling progressed, and SEALSQ expects initial commercial revenues from this product by the end of H2 2026. QS7001 evaluation kits, available since November 2025, continue to be deployed into enterprise customer environments, supporting a 12–18 month sales and integration cycle that is expected 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.” Regulatory and market backdropGlobal regulators and standards bodies are moving forward with post-quantum cryptography adoption, creating a supportive backdrop for SEALSQ’s offerings: NIST has finalized initial post-quantum standards and is progressing with CNSA 2.0, which guides U.S. federal agencies in transitioning to quantum-resistant algorithms. The European Commission and national agencies are establishing deadlines for migration to post-quantum cryptography across critical infrastructure, with some regulators requiring crypto-agile architectures in newly deployed systems. ANSSI, the French national cybersecurity agency, has indicated that it will cease certifying non–quantum-resistant security products within a defined timeframe, further accelerating the need for compliant, post-quantum-ready solutions. The EU Cyber Resilience Act and related digital regulations are reinforcing hardware-based security requirements, particularly for connected and industrial devices. 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. SEALQuantum Fund 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: Quantum hardware and interconnects, including investments in silicon spin-qubit processors, electrons-on-helium qubits and photonics-based quantum interconnects. Semiconductor design and vertical integration, anchored by IC’ALPS and complemented by initiatives in design, IP and manufacturing partnerships. Digital infrastructure, space and AI compliance, including orbital platforms and AI-driven regulatory technology integrating post-quantum security. 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. Completed the acquisition of Miraex SA, adding photonics-based quantum interconnect capabilities and strengthening the Company’s “Root-to-Qubit” architecture. Increased its ownership in Wecan Group to a majority position, supporting the integration of SEALSQ’s post-quantum cryptography and hardware root-of-trust into AI-driven compliance tools serving more than 100 financial institutions. Participated as a lead investor in Quobly’s €115 million Series A financing round, expanding collaboration in silicon spin-qubit processors and securing governance rights aligned with SEALSQ’s long-term strategy. Expanded its commitment to EeroQ through additional investment and a lead role in an upcoming financing round, reinforcing SEALSQ’s exposure to electrons-on-helium qubit technology as part of a diversified quantum portfolio. Advanced commercialization of its post-quantum semiconductor portfolio, including QS7001 achieving NIST SP 800-90B Entropy Source Validation and passing key Common Criteria fault-injection and side-channel resistance tests. Progressed customer evaluations of QS7001 and QVault TPM, with more than fifteen prospective customers and partners actively evaluating the platform and initial production revenues expected in H2 2026. Established U.S. market partnerships with Lattice Semiconductor, including a proof-of-concept TPM-FPGA solution demonstrated at Embedded World 2026. Supported the buildout of Quantix Edge Security in Murcia, Spain, a €40 million sovereign semiconductor initiative expected to contribute revenue in H2 2026. Collectively, these actions are intended to position SEALSQ as a vertically integrated participant in both post-quantum security and quantum computing markets.

FY2025 revenue rose 62% to CHF 19.3 million, driven by SEALSQ (CHF 18.3 million, with Q4 at CHF 8 million) as WISeKey shifts from legacy security products toward post‑quantum semiconductor platforms and sampling-related sales. The commercial pipeline exceeds $200 million with more than $60 million tied to the QS7001 and QVault TPM programs; QS7001 has passed EAL5+ fault‑injection/side‑channel tests and NIST validation, and first production revenues are targeted in late 2026. Liquidity and funding strengthened materially — CHF 429 million in cash and short‑term investments at end‑2025, rising to over CHF 535 million by April 30, 2026 after a CHF 125 million raise, and the SEALSQ Quantum Fund expanded to CHF 200 million to support R&D, manufacturing scale and M&A. Interested in WISeKey International Holding Ltd. Sponsored ADR? Here are five stocks we like better. WISeKey International (NASDAQ:WKEY) reported audited full-year 2025 revenue of CHF 19.3 million, up 62% from CHF 11.9 million in 2024, as the company highlighted progress in shifting from legacy security products toward post-quantum semiconductor platforms and a more integrated “convergence” strategy across its business lines. Founder and CEO Carlos Moreira said 2025 was “a defining year” for the company, citing both revenue momentum and a balance sheet that he described as “fundamentally transformed.” He said subsidiary SEALSQ contributed CHF 18.3 million of 2025 revenue, representing 66% growth year-over-year, with fourth-quarter revenue of CHF 8 million. → Roblox Stock Slides to New Low as Safety Changes Weigh on Outlook Chief Financial Officer John O’Hara said Q4 revenue doubled to CHF 8 million from CHF 4 million in the fourth quarter of 2024. O’Hara added that approximately CHF 3.5 million of the full-year increase was attributable to five months of revenue from IC’Alps, which SEALSQ acquired on Aug. 4, 2025 and consolidated from that date. Management attributed organic growth to a recovery in core secure microcontroller and public key infrastructure (PKI) product families, along with “initial sampling revenue” from post-quantum platforms. → The Real SpaceX Play: 5 Chip Stocks Powering the IPO Before It Launches Moreira emphasized that the company’s transition from sampling to commercial revenue is underway and said SEALSQ’s 2025 growth reflected renewed demand in its “legacy semiconductor and PKI product line” as customers worked through inventory, as well as the first sampling-related revenue from post-quantum products. He said SEALSQ’s commercial pipeline exceeds $200 million covering potential opportunities from 2026 through 2029, with more than $60 million tied directly to the QS7001 and QVault TPM programs, which he said grew more than five-fold year-over-year from roughly $11 million. → 3 Emerging Markets ETFs to Maximize Exposure to High-Potential Countries On certification, Moreira said QS7001 has passed fault injection and side-channel attack resistance evaluation at the EAL5+ level, and that the company has completed NIST validation. He and O’Hara both pointed to late 2026 as the target period for first production revenues tied to QS7001, framing certification as a “gating event” that helps convert pipeline into recurring hardware revenue. O’Hara said the company posted a 2025 net loss of CHF 38.2 million. He attributed the loss largely to CHF 8.3 million of non-cash share-based compensation, consolidation following the IC’Alps acquisition, increased R&D investment to accelerate post-quantum semiconductor products, and expanded sales and marketing expenses intended to support an expected commercial ramp. He said those items were partially offset by a one-off credit tied to settlement of the ExWorks loan and interest income on cash deposits. On liquidity, O’Hara said WISeKey ended 2025 with CHF 429 million in cash and short-term investments, up from CHF 91 million at the end of 2024. He noted this increase occurred while the company deployed about CHF 23 million toward strategic investments during the year. He added that in March 2026, SEALSQ raised an additional CHF 125 million. As of April 30, 2026, O’Hara said the WISeKey group held more than CHF 535 million in cash and short-term investments, positioning it to fund post-quantum R&D, scale manufacturing capacity, pursue selective M&A, and continue deploying capital through the SEALSQ Quantum Fund. Moreira said the SEALSQ Quantum Fund expanded from CHF 20 million at launch in 2025 to CHF 200 million of available capital resources as of April 30, 2026, with approximately CHF 23.2 million deployed across five portfolio positions. He described the investments as supporting vertical integration rather than “adjacent bets.” IC’Alps: CHF 14 million, adding more than 100 ASIC engineers in Grenoble and supporting development of a quantum-resistant secure element optimized for CRYSTALS-Kyber. Quantix Edge Security (Murcia, Spain): CHF 4.2 million toward a post-quantum semiconductor personalization center, which Moreira said is co-funded with Spain’s SETT.es, including a CHF 20 million contribution from the Spanish government. WeCan Group: CHF 4 million to integrate post-quantum secure digital identity into financial KYC. EeroQ/Anchor (Chicago): two rounds of investment described as aligned with SEALSQ’s CMOS-compatible semiconductor focus. ColibriTD: an initial investment tied to improving sub-7nm wafer yields, which Moreira said could reduce chip manufacturing costs. Moreira also said the company plans to demonstrate a joint quantum security stack at a Geneva Quantum Center of Excellency that is in preparation and targeted for inauguration in October. Moreira said WISeKey’s “year of convergence” involves integrating five pillars—SEALSQ, WiseSat, SEALCOIN, WISeID/INES, and WISe.ART—into a single vertically integrated “quantum secure platform.” On WiseSat, he said the company has launched 21 satellites to date, with 14 operational in low Earth orbit, and remains on track toward a 100-satellite constellation. Moreira said a definitive business combination agreement signed in November with Columbus Acquisition Corporation is expected to close in the second half of 2026, “very likely” around September, resulting in WISeSat.Space Holdings being listed on Nasdaq. He said WISeKey and SEALSQ would receive 25 million shares at $10 per share, representing $250 million of equity value, while retaining majority ownership. During Q&A, Moreira described WiseSat’s early constellation as supporting track-and-trace and connectivity use cases in areas where terrestrial coverage is limited, including logistics and military-related applications. He also discussed embedding a crypto wallet into satellites tied to SEALCOIN, which he said is 80% owned by WISeKey in cooperation with Hedera. On regulation, Moreira pointed to the U.S. government’s CNSA 2.0 mandate, which he said requires CNSA 2.0 compliance for new national security system acquisitions by Jan. 1, 2027, and said federal agencies must identify and remediate quantum-vulnerable systems. He said the company is seeing this translate into pipeline activity in areas including defense and smart meters. O’Hara said the company is reaffirming its full-year 2026 revenue guidance of 50% to 100% growth year-over-year, driven primarily by SEALSQ. He cited drivers including full-year consolidation of IC’Alps, entry into the trusted platform module market via QVault TPM, QASIC custom post-quantum ASIC engagements, QS7001 production revenues following EAL5+ certification late in 2026, initial revenues from the Quantix Edge Security personalization center development, and continued expansion of recurring PKI subscription revenue.

Geneva, Switzerland, March 31, 2026 (GLOBE NEWSWIRE) -- Conference Call to be Held on April 1 at 9:00am ET Audited FY 2025 revenue of $18 million, representing 66% growth year-over-year Entered 2026 with a strong commercial momentum and expects Q1 2026 revenue to exceed $4 million and grow over 100% as compared to Q1 2025 Reaffirms FY 2026 guidance with revenue expected to grow between 50%-100% year over year Strong cash and short-term investments of over $525 million as of March 31, 2026, well positions SEALSQ to execute growth strategy Active business pipeline exceeding $200 million for 2026–2029, including over $60 million linked to QS7001 and QVault TPM programs Good progress on partnerships and investments Strategy to establish SEALSQ as a cornerstone player at the intersection of secure semiconductors, Post-Quantum cryptography, and Quantum Technologies SEALSQ Corp (NASDAQ: LAES) (“SEALSQ” or the “Company”), a global leader in semiconductor, PKI, and Post-Quantum security technologies, today announces audited results for full year (“FY”) 2025, provides first quarter 2026 revenue expectations, and reaffirms FY 2026 revenue guidance. FY 2025 Key Financial and Operational Highlights FY 2025 revenue reached $18.3 million, representing a 66% increase year-over-year, of which $8 million was generated in Q4 2025, as compared to $4 million in Q4 2024. Revenue growth was driven by renewed demand across core semiconductor and PKI product lines and five months of revenue contribution from IC'ALPS SAS (“IC’ALPS”) following its acquisition on August 4, 2025 (approximately $3.5 million). The 2025 numbers reflected the transitional period between the traditional product offerings and next-generation Post-Quantum semiconductor platforms, and included initial revenues from sampling the Post-Quantum technology products, with the transition expected to enter its commercialization phase with the first production revenues anticipated in the latter part of 2026. FY 2025 net loss of $34.2 million. This 61% increase against the net loss in FY 2024 includes a non-cash share based compensation charge of $11.2 million, in addition to increased operating expenses due to the consolidation of IC’ALPS since August 2025, an increase in general & administrative expenses due primarily to the engagement of SEALSQ Corp’s management team and certain central functions beginning in January 2025, as well as further investment made in our research & development, and sales & marketing efforts designed to accelerate growth with the launch of the new Post-Quantum semiconductor product range. Ended the year with a strong balance sheet. As of December 31, 2025, SEALSQ held over $425 million in cash and short term investments, providing one of the strongest liquidity positions in its sector, even after deploying $30 million during the past year toward strategic investments in WeCan Group, IC’ALPS, Quantix Edge Security and WISeSat.Space (WISeSat), a secure satellite and critical digital satellite infrastructure company and a subsidiary of SEALSQ’s parent company, WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company. SEALSQ raised approximately $125 million in March 2026. As of March 31, 2026, SEALSQ has over $525 million in cash and short-term investments. This capital base enables accelerated Post-Quantum R&D, manufacturing scale-up, strategic acquisitions and ecosystem investments and vertical integration in ASIC design and quantum infrastructure. Active business pipeline estimated to total over $200 million as of March 31, 2026, reflecting potential revenue opportunities with both current and potential new customers from 2026 through 2029, including $60 million linked to QS7001 and QVault TPM programs. This pipeline highlights rising global demand for quantum-resistant security and sovereign semiconductor design and the continued evolution of our business development activities. These figures reflect management estimates and are subject to conversion risks, customer validation and technical integration. Carlos Moreira, CEO of SEALSQ, stated: “Our 66% revenue growth in 2025, coupled with early indications that Q1 2026 revenue will exceed $4 million, represents a decisive inflection point for SEALSQ. These results underscore the strength of our strategy and signal our transition from a capital-intensive development and investment cycle into a phase of commercial acceleration. We are now entering a period defined by execution and scale. Backed by more than $525 million in cash and short-term investments, and supported by a robust pipeline of over $200 million in potential new revenue opportunities, SEALSQ is strategically positioned to become a cornerstone player in sovereign security semiconductor, quantum-security and quantum technologies ecosystems worldwide.” Mr. Moreira continued, “At the same time, accelerating global demand for quantum-resistant cybersecurity, driven in particular by US regulation like CNSA 2.0 and sovereign semiconductor solutions, is reshaping the competitive landscape. Governments and enterprises alike are prioritizing secure, future-proof infrastructure, creating a powerful tailwind for our technologies. Against this backdrop, SEALSQ is uniquely positioned to play a foundational role in the emerging Quantum-security and sovereign semiconductor ecosystems worldwide with a unique ability to deliver catalog chips, custom secure ASICs, and security IP. Our focus is clear: convert technological leadership into commercial success, deepen strategic partnerships, and establish SEALSQ as a trusted cornerstone in next-generation digital security and quantum infrastructure.” Quantum Shield QS 7001 Accreditation Process SEALSQ reaffirmed that the QS7001 certification process is progressing substantially in line with the timeline that had previously been communicated. We have received written confirmation from the certification body that the most critical part of the Common Criteria evaluation required to achieve Evaluation Assurance Level (EAL) 5+, namely fault injection and side-channel attacks, confirming the QS7001’s resistance, passed in March as anticipated. The testing laboratory is now finalizing the administrative steps to issue the formal Common Criteria lab letter, expected in early April. This largely administrative delay has no impact on the overall certification process or our expected timeline to receive first production revenues in late 2026. Validation Entropy Source Validation (ESV) The independent laboratory has completed its evaluation of the Random Number Generator, a foundational component of overall security, under the National Institute of Standards and Technology FIPS SP 800-90B framework. The assessment confirmed that the chip fully complies with the required specifications, and the evaluation report has been formally submitted to NIST for review. It is important to highlight that while SEALSQ controls the delivery of evaluation milestones, the final validation timelines remain in the hands of regulatory authorities. These processes are outside of SEALSQ’s control and take time. Common Criteria On the Common Criteria front, the hardware evaluation has also been completed by this accredited laboratory. This included a comprehensive review of the overall hardware security architecture, as well as the SHA-3 hardware design, which is foundational for our Post-Quantum cryptographic capabilities. Here again, the outcome was positive and aligned with the defined security targets. We have received written confirmation from the certification body that the most critical part of the Common Criteria evaluation required to achieve Evaluation Assurance Level (EAL) 5+, namely fault injection and side-channel attacks, confirming the QS7001’s resistance, passed in March as anticipated. The testing laboratory is now finalizing the administrative steps to issue the formal Common Criteria lab letter, expected in the coming days. The report will then be submitted later on to ANSSI, which is responsible for issuing the Common Criteria EAL5+ certification. It is important to note that this is a highly sought-after hardware and software certification level, achieved by only a limited number of players. Commercial Traction SEALSQ currently has more than ten prospective customers actively evaluating the QS7001. This includes Lattice Semiconductor, with whom we have already made a public announcement and demonstrated a proof-of-concept unified TPM-FPGA solution at the Embedded World 2026 conference. SEALSQ has taken important initial steps to establish its US market presence with the announcement of partnerships with Trusted Semiconductor Solutions (a Category 1A Trusted-accredited company serving U.S. defense and government agencies) and Lattice Semiconductor (a leading provider of secure, low-power FPGAs for edge computing), which validate both the relevance of our approach and the demand for hardware-based security and Post-Quantum capabilities in the US market. SEALSQ is also engaged in advanced discussions with leading semiconductor companies around next-generation secure microcontroller platforms. Evaluation kits for our QS7001 have been available since November 2025, and in our experience, it is standard industry practice for customers to begin development and testing well before certification is fully finalized. The typical customer engagement cycle begins with an evaluation phase, where R&D teams explore the QS7001 capabilities using our evaluation kits. A key focus is the transition from traditional cryptographic algorithms such as RSA and Elliptic Curve Cryptography toward Post-Quantum cryptography libraries embedded in our platform. This is typically followed by the development and validation phase, during which customers build their software stacks, integrate them into their target devices, and perform extensive testing, including functionality, performance, and quality assurance. The Final step is industrialization. At this stage, customers provide their validated software to SEALSQ, and SEALSQ then securely provisions customers at the wafer level through our trusted supply chain. From initial evaluation to industrial deployment, this entire cycle typically spans between 12 and 18 months. SEALSQ's certification milestones are directly supporting its customer engagement efforts. The positive evaluation results achieved to date are enabling customers to advance their projects, reinforcing SEALSQ’s leadership in Post-Quantum semiconductor security. SEALSQ Enters 2026 Well Positioned for Structural Growth and Commercial Acceleration SEALSQ has entered 2026 with clear commercial momentum. The Company remains focused on scaling production, accelerating Post-Quantum innovation, expanding global partnerships, and securing its role as a leader in the emerging quantum-security infrastructure market. Q1 2026 revenue is expected to exceed $4 million, representing a substantial increase of over 100% on Q1 2025 and signaling accelerated demand across our traditional product portfolios, as our pipeline continues to grow with opportunities. Specifically, the anticipated Q1 2026 growth reflects expected increased revenue from Vault-IC secure element technology as more connected objects require internet-secure connections, and the full-quarter consolidation of IC’ALPS. FY 2026 Outlook 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 believes the strong Q1 2026 start reinforces confidence in its previously communicated FY 2026 guidance with revenue growth expected to grow between 50% and 100% year-over-year, which is supported by: A full-year consolidation of the revenue of IC’ALPS compared to five months in 2025. Continued growth in current range of secure semiconductor products as well as entry into the Trusted Platform Module (“TPM”) market.

FY 2025 STRATEGIC AND CORPORATE MILESTONES QS7001 The most consequential milestone of 2025 was the commercial launch of the Quantum Shield QS7001 in Q4. This is the world's first commercially available secure semiconductor embedding NIST-standardized Post-Quantum cryptography algorithms, ML-KEM and ML-DSA, in hardware. It delivers up to ten times higher performance than software-based implementations. SEALSQ unveiled the QS7001 at the IQT Quantum + AI Conference in New York in October and formally launched development kits at the Las Vegas Grand Prix in November. The pipeline for QS7001 and QVault TPM has already grown to over $60 million for 2026–2029, up from approximately $11.4 million at the same point last year. SEALSQ’s total active pipeline across all products stands at an estimated $200 million. These pipeline figures reflect management estimates and are subject to conversion risks, customer validation and technical integration. In March 2026, SEALSQ published a certification roadmap confirming all four product variants, QS7001 V1, QS7001 V2, QVault TPM-183, and QVault TPM-185, are on track for CC EAL5+, FIPS 140-3, and TCG certifications through Q4 2026. Acquisitions In August 2025, SEALSQ completed the acquisition of IC'ALPS SASU, a leading ASIC design specialist based in Grenoble and Toulouse (France). This added approximately 100 highly skilled engineers, bringing its global workforce to approximately 300. IC'ALPS brings expertise in custom chip design for healthcare, automotive, and IoT, and positions SEALSQ to develop the QASIC, a purpose-built Post-Quantum cryptography ASIC. ASIC revenues grew from $1.3 million in Q3 2025 to $2.3 million in Q4 2025, confirming the value of this acquisition. On March 27, 2026, IC’ALPS was officially listed as a partner by the South Korean CMOS foundry DB HiTek, with several ASIC designs already completed, including one automotive device certified to ISO 26262 ASIL-B. IC’ALPS is already recognized as a trusted partner to leading foundries, including TSMC, Intel Foundry, X-Fab, ams OSRAM, and GlobalFoundries. In addition, the growing pipeline of discussions around full-custom ASICs integrating advanced security solutions (across telecom, IoT, ID, smart card, and sovereign applications) is expected to play a significant role in advancing SEALSQ’s strategic objectives. Additionally, in March 2026, SEALSQ signed a Letter of Intent to acquire 100% of Miraex, a Swiss developer of photonics-based quantum interconnect solutions. Miraex represents a key strategic asset in completing the SEALSQ Quantum Vertical Stack. Its technology provides a critical interconnect layer linking Quantum computing, networking, and Post-Quantum cryptography into a unified architecture. Once completed, the acquisition is expected to accelerate the QSOC initiative and strengthen SEALSQ’s ability to deliver resilient, end-to-end Quantum-secure infrastructure across both terrestrial and space-based environments. Quantum Fund & Strategic Investments The SEALSQ Quantum Fund, launched in February 2025 with a $20 million initial allocation, has grown to $200 million as of today. The SEALSQ Quantum Fund is 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, a comprehensive, end-to-end “Root-to-Qubit” ecosystem aimed at ensuring technological independence, cybersecurity resilience, and trust in the emerging quantum era. SEALSQ has to date deployed approximately $30 million across IC'Alps, ColibriTD, EeroQ, WISeSat, Quantix Edge Security, and the WeCan Group, each reinforcing its Quantum vertical from silicon to space. SEALSQ’s December 2025 investment in EeroQ, with a follow-on in February 2026, is particularly strategic. EeroQ is building Quantum processors based on single electrons on superfluid helium: a design approach that yields processors as small as a thumbnail, manufacturable on standard semiconductor processes. This underpins SEALSQ’s Made in USA vision and its long-term Root-to-Qubit ecosystem. The US government and enterprise market is increasingly moving toward Roots of Trust, PKI infrastructure, and cryptographic provisioning on US soil. In November 2025, SEALSQ launched a sovereign US-based Post-Quantum Root of Trust, the first of its kind. SEALSQ partners with Trusted Semiconductor Solutions (TSS) to deliver secure, Post-Quantum-ready semiconductor solutions for the US government and defense ecosystem, combining SEALSQ’s expertise in hardware-based security and Post-Quantum cryptography with TSS’s access to trusted US supply chains and government programs. EeroQ is the Quantum computing layer of this vision. Their electron-on-helium approach allows processors as small as a thumbnail, manufacturable on standard semiconductor processes, directly aligned with SEALSQ’s long-term goal of an end-to-end sovereign Quantum security stack from Post-Quantum chips today to quantum processors in the future. Quantum Highway & Global Expansion We advanced our Quantum Highway, linking industrial capabilities across Murcia, Toulouse, Provence, Grenoble, Geneva, and Chicago. In September 2025, SEALSQ signed a €40 million joint venture with the Spanish government to establish Quantix Edge Security in Murcia, Spain's first Post-Quantum semiconductor personalization center. SEALSQ is planning to establish two additional hubs in the US and Asia with further progress anticipated to be announced in 2026. In November 2025, SEALSQ launched a sovereign US-based Post-Quantum Root of Trust, enabling US government agencies to manage Quantum-secure digital identities entirely on US soil. In November 2025, SEALSQ invested $10 million in WISeSat to develop a Quantum-secure satellite infrastructure platform. The contemplated model is based on an anticipated Irrevocable Right of Use over twelve satellites. WISeSat would retain ownership and operations while SEALSQ would secure dedicated capacity for our Quantum Spatial Orbital Cloud initiative, delivering Quantum key distribution, quantum random number generation, and Post-Quantum identity services as a subscription offering to enterprises and governments. The WISeSat 3.0 launch in June 2025 included a proof of concept for SEALCOIN’s machine-to-machine transactions secured by our semiconductor stack and Quantum RootKey. Of note, SEALCOIN is a WISeKey subsidiary and focuses on decentralized physical internet with DePIN technology and houses the development of the SEALCOIN platform. While there can be no assurance the contemplated arrangement will be completed on currently anticipated terms, this represents a significant long-term opportunity as the world’s first Quantum-secure orbital cloud.
