Is PPG Industries Inc’s (NYSE:PPG) ROE Of 23.78% Sustainable?

In this article:

With an ROE of 23.78%, PPG Industries Inc (NYSE:PPG) outpaced its own industry which delivered a less exciting 12.91% over the past year. Superficially, this looks great since we know that PPG has generated big profits with little equity capital; however, ROE doesn’t tell us how much PPG has borrowed in debt. In this article, we’ll closely examine some factors like financial leverage to evaluate the sustainability of PPG’s ROE. View our latest analysis for PPG Industries

Breaking down Return on Equity

Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. An ROE of 23.78% implies $0.24 returned on every $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 PPG Industries’s equity capital deployed. Its cost of equity is 8.84%. Since PPG Industries’s return covers its cost in excess of 14.94%, its use of equity capital is efficient and likely to be sustainable. Simply put, PPG Industries pays less for its capital than what it generates in return. ROE can be split up into three useful 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 shows how much revenue PPG Industries can generate with its current asset base. Finally, financial leverage will be our main focus today. It shows how much of assets are funded by equity and can show how sustainable the company’s capital structure is. Since financial leverage can artificially inflate ROE, we need to look at how much debt PPG Industries currently has. At 78.29%, PPG Industries’s debt-to-equity ratio appears sensible and indicates the above-average ROE is generated from its capacity to increase profit without a large debt burden.

Next Steps:

While ROE is a relatively simple calculation, it can be broken down into different ratios, each telling a different story about the strengths and weaknesses of a company. PPG Industries’s above-industry ROE is encouraging, and is also in excess of its cost of equity. ROE is not likely to be inflated by excessive debt funding, giving shareholders more conviction in the sustainability of high returns. ROE is a helpful signal, but it is definitely not sufficient on its own to make an investment decision.
