With its stock down 6.3% over the past week, it is easy to disregard Nanosonics (ASX:NAN). 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. In this article, we decided to focus on Nanosonics' ROE.

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

The formula for return on equity is:

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

So, based on the above formula, the ROE for Nanosonics is:

6.8% = AU$10m ÷ AU$151m (Based on the trailing twelve months to December 2022).

The 'return' is the yearly profit. So, this means that for every A$1 of its shareholder's investments, the company generates a profit of A$0.07.

What Has ROE Got To Do With Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don’t share these attributes.

Nanosonics' Earnings Growth And 6.8% ROE

On the face of it, Nanosonics' ROE is not much to talk about. A quick further study shows that the company's ROE doesn't compare favorably to the industry average of 9.2% either. Given the circumstances, the significant decline in net income by 2.2% seen by Nanosonics over the last five years is not surprising. We reckon that there could also be other factors at play here. Such as - low earnings retention or poor allocation of capital.

That being said, we compared Nanosonics' performance with the industry and were concerned when we found that while the company has shrunk its earnings, the industry has grown its earnings at a rate of 4.7% in the same period.

Earnings growth is a huge factor in stock valuation. It’s important for an investor to know whether the market has priced in the company's expected earnings growth (or decline). This then helps them determine if the stock is placed for a bright or bleak future. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Nanosonics is trading on a high P/E or a low P/E, relative to its industry.

Is Nanosonics Efficiently Re-investing Its Profits?

Nanosonics doesn't pay any dividend, meaning that potentially all of its profits are being reinvested in the business, which doesn't explain why the company's earnings have shrunk if it is retaining all of its profits. So there could be some other explanations in that regard. For instance, the company's business may be deteriorating.

Summary

On the whole, we feel that the performance shown by Nanosonics can be open to many interpretations. While the company does have a high rate of reinvestment, the low ROE means that all that reinvestment is not reaping any benefit to its investors, and moreover, its having a negative impact on the 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. Are these analysts expectations based on the broad expectations for the industry, or on the company's fundamentals? Click here to be taken to our analyst's forecasts page for the company.
