Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). By way of learning-by-doing, we'll look at ROE to gain a better understanding of Amgen Inc. (NASDAQ:AMGN).

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?

ROE can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Amgen is:

75% = US$3.8b ÷ US$5.0b (Based on the trailing twelve months to March 2024).

The 'return' is the yearly profit. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.75.

Does Amgen Have A Good ROE?

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. Pleasingly, Amgen has a superior ROE than the average (15%) in the Biotechs industry.

That is a good sign. With that said, a high ROE doesn't always indicate high profitability. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk. Our risks dashboardshould have the 3 risks we have identified for Amgen.

The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

Combining Amgen's Debt And Its 75% Return On Equity

It appears that Amgen makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 12.75. While its ROE is no doubt quite impressive, it could give a false impression about the company's returns given that its huge debt could be boosting those returns.

Conclusion

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
