SEALSQ Reports Revenue Doubling Amid Rising Costs
The Geneva-based chipmaker saw top-line growth surge by 131% in the first half of 2026, though the company remains in the red due to heavy investment in post-quantum security standards.
SEALSQ Corp has published its financial results for the six-month period ending in June 2026, revealing a significant acceleration in commercial activity. The company reported revenue of $11.15 million, a 131% increase compared to the same period last year. This growth is primarily attributed to renewed demand for its secure-element chips and the consolidation of a custom chip design firm acquired in late 2025.
Despite the strong top-line performance, SEALSQ continues to operate at a loss. The net loss for the period was $27.79 million, up from $20.03 million in the prior year. This reflects a strategic choice to prioritize long-term infrastructure over immediate profitability, with the company holding a cash balance of approximately $495 million to fund its expansion.
Financial Growth Driven by Security Demand
The revenue increase was fueled by several factors, including subscriptions to public key infrastructure services and design revenue from its engineering center in Spain. Gross margins also improved significantly, rising to 48.5% from 33.7% a year earlier. This expansion indicates that the company is selling a higher proportion of high-margin engineering services alongside its hardware products, according to reports from GN technics/hardware.
However, operating expenses climbed to $37.57 million, a 64% increase. The largest driver was research and development, which saw an 84% jump as the company pursued rigorous security certifications. General and administrative costs also rose to support corporate expansion and the integration of recent acquisitions. Management reaffirmed its full-year revenue guidance of $27 million to $36 million, citing a pipeline of future contracts exceeding $225 million.
Post-Quantum Certifications Take Center Stage
A core part of SEALSQ’s strategy is preparing hardware for a future where traditional encryption is vulnerable to quantum computers. The company has achieved key milestones, including NIST entropy source validation for its QS7001 chip. It has also completed fault-injection testing required for Common Criteria EAL5+ evaluation, a high standard for cryptographic modules. These steps are critical for gaining trust in government and enterprise security sectors.
The company is now distributing engineering samples of its QVault Trusted Platform Module to over 30 potential customers. Initial commercial revenue from these new products is expected to begin in the latter half of 2026. The trade-off is that these certifications and product developments require substantial upfront investment, contributing to the current operating losses while building the foundation for future market entry.
Acquisitions Expand the Sovereign Stack
SEALSQ is actively building an integrated ecosystem through strategic acquisitions. It has completed the acquisition of Miraex SA to add quantum-photonic interconnect technology. Additionally, the company took a controlling stake in Wecan Group to support AI-driven compliance solutions. These moves are part of a broader $200 million allocation for its sovereign vertical stack, aiming to control more of the security supply chain.
The company also participated in funding rounds for quantum developers, including Quobly and EeroQ. These investments are designed to secure the supply chain and foster innovation in post-quantum technologies. While this diversification reduces reliance on single product lines, it also increases complexity and integration challenges, which are reflected in the rising administrative costs reported in the financial statements.
