REGENXBIO Inc. (NASDAQ:RGNX) Held Back By Insufficient Growth Even After Shares Climb 29%

Simply Wall St

REGENXBIO Inc. (NASDAQ:RGNX) shares have continued their recent momentum with a 29% gain in the last month alone. Looking back a bit further, it's encouraging to see the stock is up 32% in the last year.

In spite of the firm bounce in price, REGENXBIO may still look like a strong buying opportunity at present with its price-to-sales (or "P/S") ratio of 4x, considering almost half of all companies in the Biotechs industry in the United States have P/S ratios greater than 10.5x and even P/S higher than 89x aren't out of the ordinary. However, the P/S might be quite low for a reason and it requires further investigation to determine if it's justified.

How Is REGENXBIO's Revenue Growth Trending?

In order to justify its P/S ratio, REGENXBIO would need to produce anemic growth that's substantially trailing the industry.

Retrospectively, the last year delivered an exceptional 75% gain to the company's top line. Still, revenue has fallen 68% in total from three years ago, which is quite disappointing. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenues over that time.

Looking ahead now, revenue is anticipated to climb by 38% each year during the coming three years according to the ten analysts following the company. With the industry predicted to deliver 126% growth each year, the company is positioned for a weaker revenue result.

With this in consideration, its clear as to why REGENXBIO's P/S is falling short industry peers. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.
