Recent performance snapshot

Sidus Space (SIDU) has been drawing fresh attention after a turbulent stretch for the stock, with a decline of about 14% in the latest session and mixed returns across recent periods.

Over the past week the stock fell about 10%, while it is up roughly 16% over the past month and about 81% over the past 3 months. Year to date, the share price is down around 13%, and the 1 year total return is very large at roughly 145%. In contrast, the 3 year total return declined about 82%.

This mix of a sharp 14.1% one day share price decline, a strong 3 month share price return of 81.3%, and a very large 1 year total shareholder return suggests sentiment has swung rapidly as investors reassess both opportunity and risk at around $3.77 a share.

With Sidus Space still loss making, yet trading at about a 165% discount to one published analyst price target of $10, the key question is whether the current price underestimates future potential or already reflects optimistic growth expectations.

Preferred Price to Book Multiple of 6.4x: Is it justified?

On a P/B basis, Sidus Space trades at 6.4x, which is materially lower than the 20.7x average for its peer group but higher than the 3.8x average across the wider US Aerospace and Defense industry.

P/B compares the company’s market value to its book value, which can be a useful lens for an early stage, loss making business where earnings based ratios are less informative. At around $3.77 a share, investors are paying a premium to the sector’s book value benchmark, even though Sidus Space does not yet have meaningful revenue at roughly $4m and continues to report losses.

The tension for anyone looking at this stock is clear. The market is pricing in a higher multiple than the broader industry, despite a track record of widening losses of about 33.4% per year over the past 5 years and no current profitability. Against that, the lower multiple relative to the 20.7x peer average suggests some investors may see Sidus Space as a cheaper way to access the commercial space and AI infrastructure theme compared with other, more highly valued peers.

The result is a mixed picture, with Sidus Space looking expensive versus the broader Aerospace and Defense space, but cheaper than a narrower peer set that trades on much richer book value multiples. This leaves any P/B based view highly dependent on an investor’s chosen comparison group.

Result: Price-to-book of 6.4x (ABOUT RIGHT)

However, you still need to weigh risks such as ongoing losses of about $28.3m on roughly $3.5m of revenue and the possibility that analyst targets are revised.
