PyroGenesis Inc.'s (TSE:PYR) Share Price Not Quite Adding Up

When close to half the companies in the Commercial Services industry in Canada have price-to-sales ratios (or "P/S") below 1.1x, you may consider PyroGenesis Inc. (TSE:PYR) as a stock to avoid entirely with its 6.5x P/S ratio. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

What Does PyroGenesis' P/S Mean For Shareholders?

The revenue growth achieved at PyroGenesis over the last year would be more than acceptable for most companies. Perhaps the market is expecting this decent revenue performance to beat out the industry over the near term, which has kept the P/S propped up. However, if this isn't the case, investors might get caught out paying too much for the stock.

Is There Enough Revenue Growth Forecasted For PyroGenesis?

PyroGenesis' P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

Taking a look back first, we see that the company managed to grow revenues by a handy 15% last year. Ultimately though, it couldn't turn around the poor performance of the prior period, with revenue shrinking 53% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for a contraction of 3.0% shows the industry is more attractive on an annualised basis regardless.

With this information, it's strange that PyroGenesis is trading at a higher P/S in comparison. In general, when revenue shrink rapidly the P/S premium often shrinks too, which could set up shareholders for future disappointment. Maintaining these prices will be extremely difficult to achieve as a continuation of recent revenue trends is likely to weigh down the shares eventually.

What Does PyroGenesis' P/S Mean For Investors?

While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

We've established that PyroGenesis currently trades on a much higher than expected P/S since its recent three-year revenues are even worse than the forecasts for a struggling industry. When we see below average revenue, we suspect the share price is at risk of declining, sending the high P/S lower. We're also cautious about the company's ability to stay its recent medium-term course and resist even greater pain to its business from the broader industry turmoil. Unless the company's relative performance improves markedly, it's very challenging to accept these prices as being reasonable.
