    Listen to the news

    SEALSQ (LAES) has agreed to raise about US$125 million through a registered direct offering of ordinary shares and warrants. The funding move is aimed at liquidity and the commercial rollout of its post quantum and quantum technologies.

    The follow on offering headlines a busy month for SEALSQ, which also outlined new quantum resilient security products and extended its collaboration with Parrot. However, the share price performance has been weak, with a 7 day share price return of 22.57% and a year to date share price return showing a 26.77% decline, alongside a 1 year total shareholder return reflecting a 7.04% decline, pointing to fading momentum into this capital raise.

    With SEALSQ’s share price under pressure, revenue of US$10.978 million and a market cap around US$591.68 million set against the recent US$125 million raise, are you looking at an undervalued quantum security player, or a stock already pricing in future growth?

    Preferred Price to Book Multiple of 4.9x: Is it justified?

    SEALSQ last closed at $3.11 and sits on a P/B of 4.9x, which screens as expensive relative to both direct peers and the wider US semiconductor industry.

    P/B compares a company’s market value to its book value, so a higher ratio usually reflects expectations for stronger future returns or valuable intangible assets. For SEALSQ, that 4.9x multiple comes alongside a current loss of $30.443 million and a history of increasing losses over the past five years, so the valuation is not being supported by profitability today.

    Against peers, SEALSQ’s 4.9x P/B is more expensive than the peer group average of 2.1x and also above the US semiconductor industry average of 4.4x. That gap suggests investors are paying a premium to sector norms even though the company is still unprofitable and has seen substantial shareholder dilution over the past year.

    Result: Price-to-book of 4.9x (OVERVALUED)

    However, you also have a US$30.443 million loss and recent share price declines, which could pressure sentiment if the capital raise and product rollout underwhelm expectations.
