Can Compagnie de Saint-Gobain SA (EPA:SGO) Continue To Outperform Its Industry?

I am writing today to help inform people who are new to the stock market and want to learn about Return on Equity using a real-life example.

Compagnie de Saint-Gobain SA (EPA:SGO) delivered an ROE of 10.9% over the past 12 months, which is an impressive feat relative to its industry average of 10.2% during the same period. Superficially, this looks great since we know that SGO has generated big profits with little equity capital; however, ROE doesn’t tell us how much SGO has borrowed in debt. In this article, we’ll closely examine some factors like financial leverage to evaluate the sustainability of SGO’s ROE.

What you must know about ROE

Return on Equity (ROE) is a measure of Compagnie de Saint-Gobain’s profit relative to its shareholders’ equity. An ROE of 10.9% implies €0.11 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 assessed against cost of equity, which is measured using the Capital Asset Pricing Model (CAPM) – but let’s not dive into the details of that today. For now, let’s just look at the cost of equity number for Compagnie de Saint-Gobain, which is 8.2%. This means Compagnie de Saint-Gobain returns enough to cover its own cost of equity, with a buffer of 2.7%. 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 shows how much revenue Compagnie de Saint-Gobain 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 ROE can be artificially increased through excessive borrowing, we should check Compagnie de Saint-Gobain’s historic debt-to-equity ratio. Currently the debt-to-equity ratio stands at a reasonable 59.9%, which means its above-average ROE is driven by its ability to grow its profit without a significant 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. Compagnie de Saint-Gobain exhibits a strong ROE against its peers, as well as sufficient returns to cover its cost of equity. Its high ROE is not likely to be driven by high debt. Therefore, investors may have more confidence in the sustainability of this level of returns going forward. ROE is a helpful signal, but it is definitely not sufficient on its own to make an investment decision.
