Geneva, Switzerland, Oct. 15, 2026 (GLOBE NEWSWIRE) --

   -- Cash, Cash Equivalents and Restricted Cash of Approximately $463 Million 
      at September 30, 2026 
 
   -- Q4 2026 Revenue Expected Between $11 Million and $20 Million 
 
   -- VaultIC408 Achieves NIST FIPS 140-3 Level 3 Validation 

SEALSQ Corp $(LAES)$ ("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 metrics for the nine-month period ended September 30, 2026 ("9M 2026"), provided an update on operational milestones, and reaffirmed its full-year 2026 revenue guidance.

9M 2026 Key Financial Metrics

   -- Revenue growth of 65%: Preliminary unaudited 9M 2026 revenue of $16.3 
      million, compared to $9.9 million in 9M 2025. 
 
   -- Strong liquidity: Cash, cash equivalents and restricted cash of 
      approximately $463.0 million at September 30, 2026. 
 
   -- Post-quantum pipeline above $100 million: An active, evolving business 
      pipeline of more than $200 million through 2029 as of October 15, 2026, 
      including more than $100 million associated with Post-Quantum projects, 
      including the QS7001 and QVault TPM. These figures represent management 
      estimates and are subject to risks such as conversion risk, customer 
      validation, technical integration and other commercial risks. 

Revenue Drivers

The 9M 2026 increase was driven primarily by:

   -- Continued strong demand for SEALSQ's Vault-IC secure-element family 
      across industrial, smart-energy IoT and P25 Radio protocol application 
      deployments. 
 
   -- Growth in recurring PKI subscriptions, certificate-management and digital 
      identity services. 
 
   -- Nine months of consolidated revenue from IC'Alps SAS, which contributed 
      approximately $3.8 million in 9M 2026 through custom ASIC design and 
      secure semiconductor engineering services. 
 
   -- Ramp-up of the Quantix Edge Security sovereign semiconductor design and 
      personalization center in Murcia, Spain. 
 
   -- Initial sampling and evaluation revenue from QS7001 and QVault TPM as 42 
      customers are now evaluating the next generation of secure semiconductor 
      products. 

FY 2026 Revenue 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 reaffirms its FY 2026 revenue growth guidance of approximately 50% to 100%, representing a range of approximately $27 million to $36 million, compared with audited FY 2025 revenue of $18 million.

Based on preliminary 9M 2026 revenue of $16.3 million, the Company expects fourth-quarter 2026 revenue of between $11 million and $20 million, compared to $8.4 million in Q4 2025. Fourth-quarter performance is expected to be supported by:

   -- Commercial ramp of the FIPS 140-3 Level 3 validated VaultIC408 in 
      government and critical-infrastructure programs, and first QVault TPM183 
      design-win shipments, subject to customer qualification. 
 
   -- Continued IC'Alps ASIC design programs, including potential custom 
      post-quantum ASIC engagements. 
 
   -- Further revenue contributions from the Quantix Edge Security project. 
 
   -- Seasonal strength in Vault-IC secure-element shipments and continued 
      growth in recurring PKI and certificate-management revenue. 

The Company expects a more significant contribution from its post-quantum product lines in 2027 and beyond as customers complete technical integration and move into volume production. Timing remains subject to laboratory review, certification, customer qualification and procurement.

Carlos Moreira, Founder, Chairman and CEO of SEALSQ, said: "Our preliminary nine-month revenue of $16.3 million represents 65% growth year-over-year, with revenue increasing sequentially in each quarter of 2026. This performance supports our reaffirmed full-year revenue outlook as we continue to advance our post-quantum products toward commercialization. With approximately $465 million in liquidity, we are well positioned to fund these priorities as we prepare for post-quantum semiconductors to become a more significant contributor to revenue in 2027."

John O'Hara, CFO of SEALSQ, added: "Based on our preliminary nine-month revenue, our reaffirmed full-year 2026 revenue guidance implies fourth-quarter revenue of $11 million to $20 million. We remain focused on converting our pipeline into production revenue and deploying capital carefully to support growth."
