Geneva, Switzerland – March 31, 2026 - 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.

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.
Page 9
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. |

Forward-Looking Statements
This communication expressly or implicitly contains certain forward-looking statements concerning SEALSQ Corp and its businesses. Forward-looking statements include statements regarding our business strategy, financial performance, results of operations, market data, events or developments that we expect or anticipate will occur in the future, as well as any other statements which are not historical facts. Although we believe that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct. These statements involve known and unknown risks and are based upon a number of assumptions and estimates which are inherently subject to significant uncertainties and contingencies, many of which are beyond our control. Actual results may differ materially from those expressed or implied by such forward-looking statements. orward-looking statements in this communication include, but are not limited to, statements regarding: anticipated Q1 2026 revenue; FY 2026 revenue guidance; our active business pipeline exceeding $200 million for 2026-2029, including over $60 million linked to QS7001 and QVault TPM programs; the expected timing and successful completion of Common Criteria EAL5+, FIPS 140-3, and TCG certifications for our QS7001 and QVault TPM product lines through Q4 2026; the anticipated commercialization of the QS7001 Post-Quantum and QVault TPM product range; the expected closing of the Miraex acquisition by end of June 2026; planned establishment of personalization hubs in the US and Asia in 2026; the development and launch of the Quantum Spatial Orbital Cloud (QSOC) satellite constellation; the expected relocation of our Geneva headquarters to the Pont-Rouge business district; the launch of a custom Post-Quantum enabled chip development with contractualization expected in the second half of 2026; expected growth in PKI subscription contracts; anticipated revenues from the Quantix Edge Security project and sovereign semiconductor initiatives; and our ability to establish SEALSQ as a cornerstone player in sovereign semiconductor and Quantum-security ecosystems worldwide.

Important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include: our ability to convert our pipeline into actual sales, as pipeline figures reflect management estimates and are subject to conversion risks, customer validation, and technical integration; the global demand for Quantum-resistant infrastructure and timing of global adoption of Quantum-resistant security; continued growth in our current range of secure microcontroller and Vault-IC secure element products; delays or failures in obtaining QS7001 or QVault TPM certifications from NIST, ANSSI, or other regulatory authorities, as certification timelines remain in the hands of regulatory authorities and are outside SEALSQ’s control; longer-than-anticipated customer evaluation and industrialization cycles; our ability to successfully launch and commercialize additional Post-Quantum chips; our ability to grow PKI subscription contracts; risks associated with the integration of IC'ALPS and the pending Miraex acquisition; execution risks associated with the Quantix Edge Security joint venture and other sovereign semiconductor initiatives; uncertainties regarding the commercial viability and market acceptance of Post-Quantum cryptography products; risks associated with our strategic investments, including those in EeroQ, WISeSat, ColibriTD, WeCan Group, and other Quantum ecosystem companies; potential delays in establishing our planned US and Asia personalization hubs; risks related to the development and deployment of the QSOC satellite constellation; the expansion of government-driven sovereign semiconductor programs; whether there will be increased enterprise demand for hardware-rooted digital trust; SEALSQ's ability to continue beneficial transactions with material parties, including a limited number of significant customers; market demand and semiconductor industry conditions; and the risks discussed in SEALSQ's filings with the SEC.
Statements regarding our business pipeline are based on management's current estimates of potential revenue opportunities and do not represent backlog or contracted revenue. Pipeline conversion is subject to numerous factors including customer validation, technical integration requirements, certification timelines, and market conditions. There can be no assurance that pipeline opportunities will convert to actual sales or that such conversion will occur within anticipated timeframes.
Statements regarding the expected timing of certifications, including Common Criteria EAL5+, FIPS 140-3, and TCG certifications, are subject to the review processes of regulatory authorities including NIST and ANSSI. While SEALSQ controls the delivery of evaluation milestones, final validation timelines remain in the hands of these regulatory authorities and may take longer than anticipated.
Statements regarding the Miraex acquisition are subject to customary closing conditions, and there can be no assurance the transaction will close on currently anticipated terms or within the expected timeframe. Statements regarding WISeSat and the QSOC initiative reflect contemplated arrangements that may not be completed on currently anticipated terms. Risks and uncertainties are further described in reports filed by SEALSQ with the SEC, including the Company's Annual Report on Form 20-F for the year ended December 31, 2025, filed with the SEC on March 31, 2026.
