There wouldn't be many who think Porton Pharma Solutions Ltd.'s (SZSE:300363) price-to-sales (or "P/S") ratio of 2.3x is worth a mention when the median P/S for the Pharmaceuticals industry in China is similar at about 2.8x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

What Does Porton Pharma Solutions' P/S Mean For Shareholders?

While the industry has experienced revenue growth lately, Porton Pharma Solutions' revenue has gone into reverse gear, which is not great. It might be that many expect the dour revenue performance to strengthen positively, which has kept the P/S from falling. You'd really hope so, otherwise you're paying a relatively elevated price for a company with this sort of growth profile.

Do Revenue Forecasts Match The P/S Ratio?

There's an inherent assumption that a company should be matching the industry for P/S ratios like Porton Pharma Solutions' to be considered reasonable.

Retrospectively, the last year delivered a frustrating 57% decrease to the company's top line. Even so, admirably revenue has lifted 33% in aggregate from three years ago, notwithstanding the last 12 months. Accordingly, while they would have preferred to keep the run going, shareholders would definitely welcome the medium-term rates of revenue growth.

Looking ahead now, revenue is anticipated to climb by 10% during the coming year according to the six analysts following the company. With the industry predicted to deliver 17% growth, the company is positioned for a weaker revenue result.

With this information, we find it interesting that Porton Pharma Solutions is trading at a fairly similar P/S compared to the industry. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. Maintaining these prices will be difficult to achieve as this level of revenue growth is likely to weigh down the shares eventually.

What We Can Learn From Porton Pharma Solutions' P/S?

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.

Given that Porton Pharma Solutions' revenue growth projections are relatively subdued in comparison to the wider industry, it comes as a surprise to see it trading at its current P/S ratio.

This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
