Cintas (NASDAQ:CTAS) has had a great run on the share market with its stock up by a significant 13% over the last three months. Given that the market rewards strong financials in the long-term, we wonder if that is the case in this instance. Specifically, we decided to study Cintas' ROE in this article.

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. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Do You 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 Cintas is:

41% = US$1.6b ÷ US$4.0b (Based on the trailing twelve months to August 2024).

The 'return' is the yearly profit. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.41.

What Is The Relationship Between ROE And 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.

A Side By Side comparison of Cintas' Earnings Growth And 41% ROE

Firstly, we acknowledge that Cintas has a significantly high ROE. Secondly, even when compared to the industry average of 11% the company's ROE is quite impressive. This probably laid the groundwork for Cintas' moderate 12% net income growth seen over the past five years.

As a next step, we compared Cintas' net income growth with the industry and found that the company has a similar growth figure when compared with the industry average growth rate of 12% 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 Cintas is trading on a high P/E or a low P/E, relative to its industry.

Is Cintas Using Its Retained Earnings Effectively?

Cintas has a healthy combination of a moderate three-year median payout ratio of 35% (or a retention ratio of 65%) and a respectable amount of growth in earnings as we saw above, meaning that the company has been making efficient use of its profits.

Moreover, Cintas is determined to keep sharing its profits with shareholders which we infer from its long history of paying a dividend for at least ten years. Based on the latest analysts' estimates, we found that the company's future payout ratio over the next three years is expected to hold steady at 36%. Still, forecasts suggest that Cintas' future ROE will drop to 32% even though the the company's payout ratio is not expected to change by much.

Conclusion

Overall, we are quite pleased with Cintas' performance. Particularly, we like that the company is reinvesting heavily into its business, and at a high rate of return. Unsurprisingly, this has led to an impressive earnings growth. With that said, the latest industry analyst forecasts reveal that the company's earnings growth is expected to slow down.
