How To Calculate Return On Equity?

The formula for ROE is:

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

So, based on the above formula, the ROE for Portillo's is:

4.0% = US$18m ÷ US$448m (Based on the trailing twelve months to September 2023).

The 'return' is the income the business earned over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.04 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. 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 Portillo's' Earnings Growth And 4.0% ROE

It is quite clear that Portillo's' ROE is rather low. Even when compared to the industry average of 17%, the ROE figure is pretty disappointing. However, the moderate 20% net income growth seen by Portillo's over the past five years is definitely a positive. Therefore, the growth in earnings could probably have been caused by other variables. Such as - high earnings retention or an efficient management in place.

Next, on comparing Portillo's' net income growth with the industry, we found that the company's reported growth is similar to the industry average growth rate of 20% over the last few years.

Earnings growth is a huge factor in stock valuation. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. 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 Portillo's is trading on a high P/E or a low P/E, relative to its industry.

Is Portillo's Efficiently Re-investing Its Profits?

Portillo's doesn't pay any dividend currently which essentially means that it has been reinvesting all of its profits into the business. This definitely contributes to the decent earnings growth number that we discussed above.
