Investors Don't See Light At End Of Equillium, Inc.'s (NASDAQ:EQ) Tunnel

Equillium, Inc.'s (NASDAQ:EQ) price-to-sales (or "P/S") ratio of 4x might make it look like a strong buy right now compared to the Biotechs industry in the United States, where around half of the companies have P/S ratios above 10.8x and even P/S above 91x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/S.

What Does Equillium's P/S Mean For Shareholders?

Equillium could be doing better as its revenue has been going backwards lately while most other companies have been seeing positive revenue growth. The P/S ratio is probably low because investors think this poor 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.

Is There Any Revenue Growth Forecasted For Equillium?

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

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 61%. At least revenue has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Therefore, it's fair to say that revenue growth has been inconsistent recently for the company.

Turning to the outlook, the next three years should bring diminished returns, with revenue decreasing 100% per year as estimated by the dual analysts watching the company. Meanwhile, the broader industry is forecast to expand by 127% per year, which paints a poor picture.

In light of this, it's understandable that Equillium's P/S would sit below the majority of other companies. However, shrinking revenues are unlikely to lead to a stable P/S over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

What We Can Learn From Equillium's P/S?

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.

With revenue forecasts that are inferior to the rest of the industry, it's no surprise that Equillium's P/S is on the lower end of the spectrum. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
