To the annoyance of some shareholders, Equillium, Inc. (NASDAQ:EQ) shares are down a considerable 54% in the last month, which continues a horrid run for the company. Longer-term shareholders will rue the drop in the share price, since it's now virtually flat for the year after a promising few quarters.

Following the heavy fall in price, Equillium may be sending very bullish signals at the moment with its price-to-sales (or "P/S") ratio of 0.7x, since almost half of all companies in the Biotechs industry in the United States have P/S ratios greater than 11.7x and even P/S higher than 66x are not unusual. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so limited.

How Equillium Has Been Performing

Equillium could be doing better as it's been growing revenue less than most other companies lately. The P/S ratio is probably low because investors think this lacklustre revenue performance isn't going to get any better. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

Keen to find out how analysts think Equillium's future stacks up against the industry? In that case, our free report is a great place to start.

Is There Any Revenue Growth Forecasted For Equillium?

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

Retrospectively, the last year delivered an exceptional 54% gain to the company's top line. Still, revenue has barely risen at all from three years ago in total, which is not ideal. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Turning to the outlook, the next year should generate growth of 0.3% as estimated by the four analysts watching the company. That's shaping up to be materially lower than the 319% growth forecast for the broader industry.

With this in consideration, its clear as to why Equillium'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.

The Final Word

Shares in Equillium have plummeted and its P/S has followed suit. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

As we suspected, our examination of Equillium's analyst forecasts revealed that its inferior revenue outlook is contributing to its low P/S. Shareholders' pessimism on the revenue prospects for the company seems to be the main contributor to the depressed P/S. The company will need a change of fortune to justify the P/S rising higher in the future.
