Whitehaven Coal Limited (ASX:WHC) delivered a less impressive 15.08% ROE over the past year, compared to the 17.04% return generated by its industry. An investor may attribute an inferior ROE to a relatively inefficient performance, and whilst this can often be the case, knowing the nuts and bolts of the ROE calculation may change that perspective and give you a deeper insight into WHC’s past performance. I will take you through how metrics such as financial leverage impact ROE which may affect the overall sustainability of WHC’s returns. View our latest analysis for Whitehaven Coal
Breaking down ROE — the mother of all ratios
Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. An ROE of 15.08% implies A$0.15 returned on every A$1 invested. Generally speaking, a higher ROE is preferred; however, there are other factors we must also consider before making any conclusions.
Return on Equity = Net Profit ÷ Shareholders Equity
ROE is measured against cost of equity in order to determine the efficiency of Whitehaven Coal’s equity capital deployed. Its cost of equity is 8.96%. Some of Whitehaven Coal’s peers may have a higher ROE but its cost of equity could exceed this return, leading to an unsustainable negative discrepancy i.e. the company spends more than it earns. This is not the case for Whitehaven Coal which is reassuring. 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
Basically, profit margin measures how much of revenue trickles down into earnings which illustrates how efficient the business is with its cost management. The other component, asset turnover, illustrates how much revenue Whitehaven Coal can make from its asset base. And finally, financial leverage is simply how much of assets are funded by equity, which exhibits how sustainable the company’s capital structure is. Since ROE can be artificially increased through excessive borrowing, we should check Whitehaven Coal’s historic debt-to-equity ratio. Currently the debt-to-equity ratio stands at a low 7.34%, which means Whitehaven Coal still has headroom to take on more leverage in order to increase profits.
Next Steps:
ROE is one of many ratios which meaningfully dissects financial statements, which illustrates the quality of a company. While Whitehaven Coal exhibits a weak ROE against its peers, its returns are sufficient enough to cover its cost of equity. Also, ROE is not likely to be inflated by excessive debt funding, giving shareholders more conviction in the sustainability of returns, which has headroom to increase further. Although ROE can be a useful metric, it is only a small part of diligent research.
