**SEALSQ Corp Announces H1 2025 Preliminary Revenue and Other Key Financial Metrics: Updates on Planned Deployment of Post-Quantum Security Solutions by 2025 Year-End**

 

*Announces FY 2025 revenue guidance of between $16.0 million to $20.0 million, representing year-on-year growth of 45% - 82%* 

 

*New Quantum Resistant Chip Offering, Quantix Edge Partnership and IC'ALPS ASIC Acquisition to Drive 2026 Revenue Surge and Global Expansion*

<br> Geneva, Switzerland, July 3, 2025 -- 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 reports its preliminary unaudited financial metrics for the six-month period ended June 30, 2025 (H1 2025). The Company also updates on its transformative operational milestones, announces initial FY 2025 revenue guidance and reaffirms outlook for 2026 and beyond.

**H1 2025 Key Financial Metrics**

&nbsp;&nbsp;&nbsp;&nbsp;· **Revenue**: H1 2025 preliminary unaudited revenue of $4.8 million, was in line with H1 2024 and, as
anticipated, reflective of the continued transitional period as the strategic pivot from legacy products to next-generation post-quantum
semiconductors and software solutions continues.

&nbsp;&nbsp;&nbsp;&nbsp;· **Cash Position**: Bolstered cash reserves of $120 million as of June 30, 2025, up from $19 million
compared to June 30, 2024, and $85 million compared to December 31, 2024, provides substantial liquidity to fuel PQC innovation and global
expansion.

**Announces Initial Full Year 2025 Revenue Guidance and Growth Catalysts**

&nbsp;&nbsp;&nbsp;&nbsp;· **2025 Full Year Outlook**: The Company anticipates full year 2025 revenue to be in the range of $16.0
million to $20.0 million, representing year-on-year growth of between 45% and 82%. This full-year outlook is based upon our best
estimates of the timing of the completion of the IC'ALPS acquisition as well as the start date for the Quantix Edge project.

&nbsp;&nbsp;&nbsp;&nbsp;· **2026 and Beyond**: The Company expects 2026 will be a period of further growth, fueled by several
new revenue streams including a full year of revenue relating to the IC'ALPS acquisition, the commencement of the Quantix Edge project,
and the revenues from the launch of the TPM Post-Quantum resistant chip. SEALSQ plans to disclose expectations as this business continues
to evolve but it currently expects 2026 to reflect similar year-on-year revenue growth in the 50% to 100% range.

&nbsp;&nbsp;&nbsp;&nbsp;· **Business Pipeline**: The Company's new business pipeline continues to grow and is now standing
at $145 million of revenue opportunities with both current and prospective clients for the period 2026 to 2028 (as of July 3, 2025). This
is driven by surging demand for quantum-resistant security solutions and sovereign semiconductor design expertise.

Carlos Moreira, CEO of SEALSQ, commented: "While H1 2025 marked the expected continuation of a transitional period as we aligned our portfolio with the post-quantum era, H2 2025 will be a pivotal inflection point for SEALSQ. With clear visibility into our current business and growth drivers, we expect our second half of the year to be substantially stronger than the first half in terms of revenue. Thus, for the second half of 2025, we expect revenues of between $11 million and $15 million, fueled by major commercial projects and the consolidation of some revenues relating to IC'ALPS."

Mr. Moreira added, "With standard QVault TPM and custom ASICs solutions, and our expanding network of Test and Personalization Centers, we are laying the foundation for important growth in 2026. Although we do not expect our Spain-based Personalization Center project to be fully activated so as to have a significant impact on our 2025 revenue, we believe it will act as a catalyst for 2026, and we expect it to generate significant revenues that year. These factors, combined with our global PQC leadership, position SEALSQ for accelerated growth in 2026. We stand at a pivotal moment in the evolution of digital trust — where semiconductor security-based solutions and quantum-resistant technologies are becoming the backbone of a digital world that is secure, connected, and built for a better future."

**Strategic Milestones Achieved in H1 2025**

&nbsp;&nbsp;&nbsp;&nbsp;· **IC'ALPS Acquisition progress** **:** in May 2025, SEALSQ signed
the Share Purchase Agreement with Doliam to acquire IC'ALPS, a French ASIC design company and official partner of Intel Foundry,
TSMC, and GlobalFoundries. The acquisition will bolster SEALSQ's custom chip and IP development capabilities, reinforcing its leadership
in building a PQC-focused hardware ecosystem. The closing of the acquisition is subject to the French government approval, expected on
or before August 15, 2025. Of note, for H1 2025, IC'ALPS generated an estimated unaudited French GAAP revenue of approximately $4.0
million, which is not included in the SEALSQ revenues for H1 2025.<br>

&nbsp;&nbsp;&nbsp;&nbsp;· **Quantix Edge Partnership:** As recently communicated, the Government of Spain has announced the launch of Quantix Edge project
through the Spanish Society for Technological Transformation. The total investment amounts to EUR 40 million, of which SEALSQ, in conjunction
with its parent WISeKey, is contributing approximately 25%. SEALSQ will provide additional updates regarding the Quantix Edge project
following the establishment of the Spanish entity which is estimated to be completed in early Q4 2025.

&nbsp;&nbsp;&nbsp;&nbsp;· **ASIC Partnership**: A multi-million-dollar custom ASIC development leveraging the QS7001 architecture,
is on track to close by Q4 2025 with a leading technology company.

&nbsp;&nbsp;&nbsp;&nbsp;· **First Investment in ColibriTD & QaaS Offering:** SEALSQ has completed a first investment in ColibriTD,
a Quantum as a Service company. The initiative is part of SEALSQ's previously announced $20 million budget allocated to invest and
develop technological synergies with Quantum companies to offer a full panel of Quantum related services in applications like Automotive,
Medtech, Space etc.

&nbsp;&nbsp;&nbsp;&nbsp;· **QUASARS Program:** Engineering samples of the QS7001™ post-quantum microcontroller already
delivered to initial partners in Q2 2025, with production samples and development kits scheduled to be shipped to customers at the end
of Q3 2025, and initial revenues expected in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;· **QVault TPM Commercialization:** Customer sampling is anticipated to begin in Q4 2025, with initial
revenue expected in 2026.

**Strategic Investments Fueling Growth**

Recent capital infusions have strengthened SEALSQ's financial position, and enabled the accelerated development of its post-quantum chip portfolio, strategic investments like the acquisition of IC'ALPS SAS for a fixed purchase price of EUR 12.5 million and the $10 million investment in WISeSat.Space for quantum-resilient satellite communication, and the progression of its global Design & Personalization Centers through the recently announced Quantix Edge Security project.

Combined with a robust cash reserve of $120 million as of June 30, 2025, these funds well-position SEALSQ to capitalize on opportunities arising from the growing demand for quantum-resistant technologies and drive commercialization in H2 2025 and beyond.
