It is hard to get excited after looking at Sono-Tek's (NASDAQ:SOTK) recent performance, when its stock has declined 7.8% over the past month. We, however decided to study the company's financials to determine if they have got anything to do with the price decline. Fundamentals usually dictate market outcomes so it makes sense to study the company's financials. Particularly, we will be paying attention to Sono-Tek's ROE today.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

Return on equity can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Sono-Tek is:

6.3% = US$1.1m ÷ US$17m (Based on the trailing twelve months to November 2024).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.06 in profit.

What Has ROE Got To Do With Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company’s earnings growth potential. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

A Side By Side comparison of Sono-Tek's Earnings Growth And 6.3% ROE

When you first look at it, Sono-Tek's ROE doesn't look that attractive. A quick further study shows that the company's ROE doesn't compare favorably to the industry average of 10% either. Therefore, Sono-Tek's flat earnings over the past five years can possibly be explained by the low ROE amongst other factors.

Next, on comparing with the industry net income growth, we found that the industry grew its earnings by 14% over the last few years.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. It’s important for an investor to know whether the market has priced in the company's expected earnings growth (or decline). By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await. Is SOTK fairly valued?

Is Sono-Tek Making Efficient Use Of Its Profits?

Sono-Tek doesn't pay any regular dividends, meaning that potentially all of its profits are being reinvested in the business. However, this doesn't explain why the company hasn't seen any growth. It looks like there might be some other reasons to explain the lack in that respect. For example, the business could be in decline.

Summary

On the whole, we feel that the performance shown by Sono-Tek can be open to many interpretations. While the company does have a high rate of profit retention, its low rate of return is probably hampering its earnings growth. Having said that, looking at current analyst estimates, we found that the company's earnings growth rate is expected to see a huge improvement.
