Do Revenue Forecasts Match The Low P/S Ratio?

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

Retrospectively, the last year delivered a frustrating 40% decrease to the company's top line. That put a dampener on the good run it was having over the longer-term as its three-year revenue growth is still a noteworthy 21% in total. So we can start by confirming that the company has generally done a good job of growing revenue over that time, even though it had some hiccups along the way.

Shifting to the future, estimates from the analysts covering the company suggest revenue should grow by 12% per year over the next three years. Meanwhile, the rest of the industry is forecast to expand by 26% per year, which is noticeably more attractive.

With this information, we can see why Array Technologies is trading at a P/S lower than the industry. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.

What We Can Learn From Array Technologies' P/S?

We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Array Technologies' analyst forecasts revealed that its inferior revenue outlook is contributing to its low P/S. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises. The company will need a change of fortune to justify the P/S rising higher in the future.
