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

Return on Equity (ROE) is a measure of OSH’s profit relative to its shareholders’ equity. For example, if OSH invests $1 in the form of equity, it will generate $0.04 in earnings from this. 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. OSH’s cost of equity is 8.55%. This means OSH’s returns actually do not cover its own cost of equity, with a discrepancy of -4.48%. This isn’t sustainable as it implies, very simply, that the company pays more 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

Essentially, profit margin shows how much money the company makes after paying for all its expenses. Asset turnover reveals how much revenue can be generated from OSH’s asset base. And finally, financial leverage is simply how much of assets are funded by equity, which exhibits how sustainable OSH’s capital structure is. Since ROE can be artificially increased through excessive borrowing, we should check OSH’s historic debt-to-equity ratio. The debt-to-equity ratio currently stands at a sensible 81.33%, meaning the ROE is a result of its capacity to produce profit growth without a huge debt burden.

What this means for you:

Are you a shareholder? OSH’s below-industry ROE is disappointing, furthermore, its returns were not even high enough to cover its own cost of equity. However, investors shouldn’t despair since ROE is not inflated by excessive debt, which means OSH still has room to improve shareholder returns by raising debt to fund new investments.
