There Is A Reason Generation Bio Co.'s (NASDAQ:GBIO) Price Is Undemanding

Simply Wall St

With a price-to-sales (or "P/S") ratio of 1.1x Generation Bio Co. (NASDAQ:GBIO) may be sending very bullish signals at the moment, given that almost half of all the Biotechs companies in the United States have P/S ratios greater than 8.5x and even P/S higher than 59x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/S.

How Generation Bio Has Been Performing

With revenue growth that's inferior to most other companies of late, Generation Bio has been relatively sluggish. Perhaps the market is expecting the current trend of poor revenue growth to continue, which has kept the P/S suppressed. If you still like the company, you'd be hoping revenue doesn't get any worse and that you could pick up some stock while it's out of favour.

What Are Revenue Growth Metrics Telling Us About The Low P/S?

There's an inherent assumption that a company should far underperform the industry for P/S ratios like Generation Bio's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 146% gain to the company's top line. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Therefore, it's fair to say that revenue growth has been inconsistent recently for the company.

Shifting to the future, estimates from the six analysts covering the company suggest revenue growth is heading into negative territory, declining 16% per year over the next three years. With the industry predicted to deliver 104% growth each year, that's a disappointing outcome.

With this information, we are not surprised that Generation Bio is trading at a P/S lower than the industry. However, shrinking revenues are unlikely to lead to a stable P/S over the longer term. There's potential for the P/S to fall to even lower levels if the company doesn't improve its top-line growth.

What Does Generation Bio's P/S Mean For Investors?

Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

It's clear to see that Generation Bio maintains its low P/S on the weakness of its forecast for sliding revenue, as expected. As other companies in the industry are forecasting revenue growth, Generation Bio's poor outlook justifies its low P/S ratio. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
