Portillo's (NASDAQ:PTLO) has had a rough three months with its share price down 28%. However, the company's fundamentals look pretty decent, and long-term financials are usually aligned with future market price movements. Specifically, we decided to study Portillo's' 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. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Is ROE Calculated?

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 Portillo's is:

6.9% = US$31m ÷ US$452m (Based on the trailing twelve months to March 2024).

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 $0.07 in profit.

What Is The Relationship Between ROE And Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. 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 all else is equal, companies that have both a higher return on equity and higher profit retention are usually the ones that have a higher growth rate when compared to companies that don't have the same features.

Portillo's' Earnings Growth And 6.9% ROE

On the face of it, Portillo's' ROE is not much to talk about. We then compared the company's ROE to the broader industry and were disappointed to see that the ROE is lower than the industry average of 18%. Despite this, surprisingly, Portillo's saw an exceptional 39% net income growth over the past five years. So, there might be other aspects that are positively influencing the company's earnings 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.

As a next step, we compared Portillo's' net income growth with the industry, and pleasingly, we found that the growth seen by the company is higher than the average industry growth of 26%.

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. Doing so will help them establish if the stock's future looks promising or ominous.

Is Portillo's Efficiently Re-investing Its Profits?

Portillo's doesn't pay any regular dividends to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Conclusion

Overall, we feel that Portillo's certainly does have some positive factors to consider. Despite its low rate of return, the fact that the company reinvests a very high portion of its profits into its business, no doubt contributed to its high earnings growth. Having said that, the company's earnings growth is expected to slow down, as forecasted in the current analyst estimates.
