With the stock now trading at a significant discount to analyst targets, the big question remains: is Arqit Quantum still flying under the radar as an undervalued play, or is the market already factoring in that future growth?

Price-to-Book Ratio of 37.4x: Is it Justified?

Arqit Quantum’s price-to-book (P/B) ratio stands at 37.4x, a level that draws attention when compared to peers. The last close was $39.03, and the valuation sits well below the peer average, yet notably above its industry benchmark.

The price-to-book ratio compares the market value of a company’s shares to its net assets. For technology businesses, especially early-stage or unprofitable ones, this multiple may reflect optimism about future growth or the market’s willingness to pay for what could be significant intellectual property rather than current profits.

The figure of 37.4x is much lower than the peer average of 98.4x. This may indicate that the market sees Arqit Quantum as less speculative than its highest-flying competitors. However, the ratio remains far above the software industry average of 3.9x, highlighting the speculative premium attached to the stock’s growth potential.
