While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we’ll use ROE to better understand Advanced Drainage Systems Inc (NYSE:WMS).
Our data shows Advanced Drainage Systems has a return on equity of 12% for the last year. That means that for every $1 worth of shareholders’ equity, it generated $0.12 in profit.
How Do You Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Advanced Drainage Systems:
12% = US$69m ÷ US$652m (Based on the trailing twelve months to June 2018.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.
What Does Return On Equity Mean?
ROE measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Advanced Drainage Systems Have A Good Return On Equity?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. You can see in the graphic below that Advanced Drainage Systems has an ROE that is fairly close to the average for the building industry (14%).
That’s not overly surprising. Generally it will take a while for decisions made by leadership to impact the ROE. So savvy investors often note how long the CEO has been in that position.
The Importance Of Debt To Return On Equity
Virtually all companies need money to invest in the business, to grow profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Advanced Drainage Systems’s Debt And Its 12% Return On Equity
While Advanced Drainage Systems does have some debt, with debt to equity of just 0.59, we wouldn’t say debt is excessive. The combination of modest debt and a very respectable ROE suggests this is a business worth watching. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.
The Bottom Line On ROE
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In my book the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
