It is hard to get excited after looking at Sonos' (NASDAQ:SONO) recent performance, when its stock has declined 16% over the past three months. However, stock prices are usually driven by a company's financial performance over the long term, which in this case looks quite promising. Specifically, we decided to study Sonos' ROE in this article.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?

ROE 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 Sonos is:

19% = US$123m ÷ US$643m (Based on the trailing twelve months to July 2022).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.19 in profit.

Why Is ROE Important For 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.

Sonos' Earnings Growth And 19% ROE

At first glance, Sonos seems to have a decent ROE. Even when compared to the industry average of 22% the company's ROE looks quite decent. This probably goes some way in explaining Sonos' significant 67% net income growth over the past five years amongst other factors. However, there could also be other drivers behind this growth. For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio.

We then compared Sonos' net income growth with the industry and we're pleased to see that the company's growth figure is higher when compared with the industry which has a growth rate of 27% in the same period.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await. 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 Sonos is trading on a high P/E or a low P/E, relative to its industry.

Is Sonos Efficiently Re-investing Its Profits?

Given that Sonos doesn't pay any dividend to its shareholders, we infer that the company has been reinvesting all of its profits to grow its business.

Summary

In total, we are pretty happy with Sonos' performance. Particularly, we like that the company is reinvesting heavily into its business, and at a high rate of return.
