POET Technologies (NasdaqCM:POET) drew fresh attention after photonics stocks rebounded, alongside growing interest in optical transmission for data centers, following high profile endorsements of optical component suppliers by Nvidia’s CEO.

Even after a sharp 9.22% one day share price drop to US$12.65, POET Technologies still sits on a 90 day share price return of 104.61% and a 1 year total shareholder return of 213%. This indicates that momentum has been strong but increasingly volatile as sentiment around photonics and data center optics shifts with each new headline.

With POET Technologies now valued at about US$2.4b on just US$1.4m of revenue and a recent 213% 1 year return, the real question is whether this excitement leaves any upside, or if the market is already pricing in future growth.

Preferred Price to Book Multiple of 4.9x: Is It Justified?

Given the recent move in POET Technologies stock, a key question is whether the current valuation lines up with its fundamentals and peers. One clear reference point is its price to book ratio, which sits at 4.9x.

The P/B multiple compares POET Technologies' market value to its book value. A higher figure usually reflects expectations for future growth or valuable intangible assets that are not yet apparent in current financials. For a company that is still unprofitable and produces limited revenue of about $1.4m, a higher P/B ratio can indicate that investors are pricing in a meaningful improvement in its business over time rather than its present earnings power.

Compared to the broader US Semiconductor industry, where the average P/B ratio is 6.2x, POET Technologies appears cheaper on this measure. However, when compared with a closer peer group that trades at an average P/B of 2.9x, the stock looks more expensive. That difference suggests the market is assigning POET Technologies a premium to peers, even though the company is currently loss making, does not have meaningful revenue and relies on higher risk external borrowing for funding, while at the same time valuing it below the broader industry average.

Result: Price-to-book of 4.9x (ABOUT RIGHT)

However, POET Technologies still carries clear risks, including ongoing losses of about US$81.6m and dependence on Asia for all reported revenue to date.
