Supernus Pharmaceuticals (NASDAQ:SUPN) has had a great run on the share market with its stock up by a significant 17% over the last three months. But the company's key financial indicators appear to be differing across the board and that makes us question whether or not the company's current share price momentum can be maintained. Specifically, we decided to study Supernus Pharmaceuticals' ROE in this article.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How To Calculate Return On Equity?

Return on equity 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 Supernus Pharmaceuticals is:

0.5% = US$5.2m ÷ US$957m (Based on the trailing twelve months to June 2024).

The 'return' is the amount earned after tax over the last twelve months. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.01.

Why Is ROE Important For Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. 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.

Supernus Pharmaceuticals' Earnings Growth And 0.5% ROE

As you can see, Supernus Pharmaceuticals' ROE looks pretty weak. Not just that, even compared to the industry average of 22%, the company's ROE is entirely unremarkable. Therefore, it might not be wrong to say that the five year net income decline of 36% seen by Supernus Pharmaceuticals was possibly a result of it having a lower ROE. However, there could also be other factors causing the earnings to decline. For instance, the company has a very high payout ratio, or is faced with competitive pressures.

Next, when we compared with the industry, which has shrunk its earnings at a rate of 0.3% in the same 5-year period, we still found Supernus Pharmaceuticals' performance to be quite bleak, because the company has been shrinking its earnings faster than the industry.

Earnings growth is an important metric to consider when valuing a stock. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. 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 Supernus Pharmaceuticals is trading on a high P/E or a low P/E, relative to its industry.

Is Supernus Pharmaceuticals Making Efficient Use Of Its Profits?

Supernus Pharmaceuticals doesn't pay any regular dividends, meaning that potentially all of its profits are being reinvested in the business, which doesn't explain why the company's earnings have shrunk if it is retaining all of its profits. So there might be other factors at play here which could potentially be hampering growth. For example, the business has faced some headwinds.

Summary

Overall, we have mixed feelings about Supernus Pharmaceuticals. Even though it appears to be retaining most of its profits, given the low ROE, investors may not be benefitting from all that reinvestment after all. The low earnings growth suggests our theory correct. Having said that, looking at current analyst estimates, we found that the company's earnings growth rate is expected to see a huge improvement.
