How Do You 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 United Therapeutics is:

16% = US$872m ÷ US$5.4b (Based on the trailing twelve months to June 2023).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.16 in profit.

What Has ROE Got To Do With Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. Assuming all else is equal, companies that have both a higher return on equity and higher profit retention are usually the ones that have a higher growth rate when compared to companies that don't have the same features.

A Side By Side comparison of United Therapeutics' Earnings Growth And 16% ROE

To start with, United Therapeutics' ROE looks acceptable. Further, the company's ROE is similar to the industry average of 20%. This certainly adds some context to United Therapeutics' exceptional 22% net income growth seen over the past five years. We believe that there might also be other aspects that are positively influencing the company's earnings growth. For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio.

We then performed a comparison between United Therapeutics' net income growth with the industry, which revealed that the company's growth is similar to the average industry growth of 22% in the same 5-year period.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. Doing so will help them establish if the stock's future looks promising or ominous. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if United Therapeutics is trading on a high P/E or a low P/E, relative to its industry.

Is United Therapeutics Efficiently Re-investing Its Profits?

United Therapeutics doesn't pay any dividend to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.
