Arqit Quantum (NasdaqCM:ARQQ) has agreed to a US$7 million settlement resolving all U.S. securities class actions, closing multi year disputes over alleged misstatements about its quantum encryption technology and revenue sources.

The recent 7 day share price return of 79.3%, including a 7.9% move in the last session to US$24.38, suggests momentum has picked up quickly, even though the 1 year total shareholder return is still down 41.5% and the 5 year total shareholder return is down 90.2%. This points to a long term record that remains weak despite the lift following Arqit Quantum’s settlement news.

With Arqit Quantum now past a long running legal overhang and trading well below the current US$60 analyst price target, the real question is whether the stock is still mispriced, or if the market now fully reflects its future potential.

Price to Book: Is Arqit Quantum’s 14.2x Multiple Justified?

At a P/B ratio of 14.2x, Arqit Quantum is priced far above both its direct peers at 2x and the broader US Software industry at 2.8x. This points to a valuation that is hard to call conservative at the last close of $24.38.

The price to book ratio compares the company’s market value to its net assets on the balance sheet. A higher multiple often implies investors are willing to pay a premium for factors such as potential future growth, margins or intangible assets that are not captured in book value. For Arqit Quantum, that premium sits against a backdrop of reported revenue of about $1.1m and a current net loss of $49.0m, so investors are effectively paying a high price relative to the existing asset and income base.

Compared with both peer averages and the wider US Software group, Arqit Quantum’s 14.2x P/B ratio is several times higher. At the same time, the company is unprofitable, carries less than one year of cash runway and has a history of shareholder dilution and recent insider selling. In this context, the current multiple appears significantly higher than the peer and industry benchmarks.

Result: Price-to-book of 14.2x (OVERVALUED)

However, Arqit Quantum still carries risks, including its current net loss of US$49.0m and less than one year of cash runway, which could put pressure on future funding needs.
