With its stock down 19% over the past three months, it is easy to disregard Alkermes (NASDAQ:ALKS). However, stock prices are usually driven by a company's financial performance over the long term, which in this case looks quite promising. Specifically, we decided to study Alkermes' ROE in this article.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Do You Calculate Return On Equity?

The formula for return on equity is:

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

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

45% = US$570m ÷ US$1.3b (Based on the trailing twelve months to March 2024).

The 'return' is the income the business earned over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.45 in profit.

What Is The Relationship Between ROE And Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don't share these attributes.

Alkermes' Earnings Growth And 45% ROE

To begin with, Alkermes has a pretty high ROE which is interesting. Secondly, even when compared to the industry average of 15% the company's ROE is quite impressive. As a result, Alkermes' exceptional 70% net income growth seen over the past five years, doesn't come as a surprise.

Next, on comparing with the industry net income growth, we found that Alkermes' growth is quite high when compared to the industry average growth of 15% in the same period, which is great to see.

Earnings growth is a huge factor in stock valuation. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. This then helps them determine if the stock is placed for a bright or bleak future.

Summary

On the whole, we feel that Alkermes' performance has been quite good. Particularly, we like that the company is reinvesting heavily into its business, and at a high rate of return.
