How Has Sono-Tek Performed Recently?

Sono-Tek could be doing better as its revenue has been going backwards lately while most other companies have been seeing positive revenue growth.

What Are Revenue Growth Metrics Telling Us About The High P/S?

Sono-Tek's 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, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 4.3%. This has erased any of its gains during the last three years, with practically no change in revenue being achieved in total. So it appears to us that the company has had a mixed result in terms of growing revenue over that time.

Shifting to the future, estimates from the two analysts covering the company suggest revenue should grow by 15% per year over the next three years. With the industry predicted to deliver 23% growth each year, the company is positioned for a weaker revenue result.

With this information, we find it concerning that Sono-Tek is trading at a P/S higher than the industry. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as this level of revenue growth is likely to weigh heavily on the share price eventually.

The Bottom Line On Sono-Tek'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.

We've concluded that Sono-Tek currently trades on a much higher than expected P/S since its forecast growth is lower than the wider industry. The weakness in the company's revenue estimate doesn't bode well for the elevated P/S, which could take a fall if the revenue sentiment doesn't improve. At these price levels, investors should remain cautious, particularly if things don't improve.
