Can South32 Limited’s (ASX:S32) ROE Continue To Surpass The Industry Average?

South32 Limited (ASX:S32) outperformed the Diversified Metals and Mining industry on the basis of its ROE – producing a higher 12.52% relative to the peer average of 11.83% over the past 12 months. While the impressive ratio tells us that S32 has made significant profits from little equity capital, ROE doesn’t tell us if S32 has borrowed debt to make this happen. Today, we’ll take a closer look at some factors like financial leverage to see how sustainable S32’s ROE is. Check out our latest analysis for South32

Peeling the layers of ROE – trisecting a company’s profitability

Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. It essentially shows how much S32 can generate in earnings given the amount of equity it has raised. In most cases, a higher ROE is preferred; however, there are many other factors we must consider prior to making any investment decisions.

Return on Equity = Net Profit ÷ Shareholders Equity

Returns are usually compared to costs to measure the efficiency of capital. S32’s cost of equity is 9.94%. This means S32 returns enough to cover its own cost of equity, with a buffer of 2.59%. This sustainable practice implies that the company pays less for its capital than what it generates in return. ROE can be dissected into three distinct ratios: net profit margin, asset turnover, and financial leverage. This is called the Dupont Formula:

Dupont Formula

ROE = profit margin × asset turnover × financial leverage

ROE = (annual net profit ÷ sales) × (sales ÷ assets) × (assets ÷ shareholders’ equity)

ROE = annual net profit ÷ shareholders’ equity

The first component is profit margin, which measures how much of sales is retained after the company pays for all its expenses. Asset turnover reveals how much revenue can be generated from S32’s asset base. And finally, financial leverage is simply how much of assets are funded by equity, which exhibits how sustainable S32’s capital structure is. Since financial leverage can artificially inflate ROE, we need to look at how much debt S32 currently has. The debt-to-equity ratio currently stands at a low 10.11%, meaning the above-average ROE is due to its capacity to produce profit growth without a huge debt burden.
