Assessing SEALSQ (LAES) Valuation After Quantum Security Launches And Certification Progress

SEALSQ (LAES) is back on investor radar after a cluster of quantum security milestones, including QS7001 certification progress, audited 2025 results with reaffirmed 2026 growth guidance, and new chip personalization centers in the US and India.

See our latest analysis for SEALSQ.

Despite an active few weeks of product updates, consortium work and reaffirmed 2026 guidance, SEALSQ’s share price has come under pressure, with a 30 day share price return of a 36.22% decline and a 90 day share price return of a 41.04% decline, while the 1 year total shareholder return is a comparatively modest 1.96% decline. This suggests short term momentum has cooled even as the longer term picture looks less severe.

With SEALSQ shares under pressure despite certification milestones, consortium deals and reaffirmed 2026 guidance, the key question now is simple: are investors being offered a discounted entry into quantum security, or is the market already pricing in future growth?

Preferred Price-to-Sales of 25.3x: Is it justified?

SEALSQ last closed at $2.50, and its current valuation is framed by a P/S ratio of 25.3x, which sits well above both peers and the broader US semiconductor group.

The P/S ratio compares the company’s market value to its revenue, so a higher figure generally reflects investors assigning a richer value to each dollar of sales. For a young, unprofitable chip and security player like SEALSQ, that usually signals that the market is focusing less on current losses and more on revenue potential and the quantum security niche it serves.

However, SEALSQ’s P/S of 25.3x is described as expensive versus the US Semiconductor industry average of 5.7x and a peer average of 6.8x. It is also high compared to an estimated fair P/S ratio of 11.3x. This suggests a level the market could move towards if expectations or sentiment cool. On that basis, the current multiple embeds a lot of optimism relative to sales today.

Result: Price-to-sales of 25.3x (OVERVALUED)

However, there are clear risks. These include SEALSQ’s reported net loss of $34.194 million and a P/S multiple that already prices in a lot of optimism.
