Southern Copper (NYSE:SCCO) has had a great run on the share market with its stock up by a significant 45% over the last three months. Given that stock prices are usually aligned with a company's financial performance in the long-term, we decided to study its financial indicators more closely to see if they had a hand to play in the recent price move. Particularly, we will be paying attention to Southern Copper's ROE today.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Do You Calculate Return On Equity?

Return on equity 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 Southern Copper is:

33% = US$2.4b ÷ US$7.5b (Based on the trailing twelve months to December 2023).

The 'return' is the yearly profit. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.33 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. 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.

Southern Copper's Earnings Growth And 33% ROE

Firstly, we acknowledge that Southern Copper has a significantly high ROE. Additionally, the company's ROE is higher compared to the industry average of 10.0% which is quite remarkable. Probably as a result of this, Southern Copper was able to see a decent net income growth of 17% over the last five years.

As a next step, we compared Southern Copper's net income growth with the industry and were disappointed to see that the company's growth is lower than the industry average growth of 23% in the same period.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. 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.

Is Southern Copper Using Its Retained Earnings Effectively?

While Southern Copper has a three-year median payout ratio of 90% (which means it retains 9.7% of profits), the company has still seen a fair bit of earnings growth in the past, meaning that its high payout ratio hasn't hampered its ability to grow.

Moreover, Southern Copper 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 81%. However, Southern Copper's ROE is predicted to rise to 40% despite there being no anticipated change in its payout ratio.

Summary

In total, it does look like Southern Copper has some positive aspects to its business. The company has grown its earnings moderately as a result of its impressive ROE. Yet, the business is retaining hardly any of its profits. This might have negative implications on the company's future growth. That being so, a study of the latest analyst forecasts show that the company is expected to see a slowdown in its future earnings growth.
