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 Cogstate is:

13% = US$5.4m ÷ US$41m (Based on the trailing twelve months to June 2024).

The 'return' is the amount earned after tax over the last twelve months. Another way to think of that is that for every A$1 worth of equity, the company was able to earn A$0.13 in profit.

What Has ROE Got To Do With 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. 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.

Cogstate's Earnings Growth And 13% ROE

To start with, Cogstate's ROE looks acceptable. Further, the company's ROE compares quite favorably to the industry average of 11%. Probably as a result of this, Cogstate was able to see an impressive net income growth of 42% over the last five years. However, there could also be other causes behind this 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.

As a next step, we compared Cogstate's net income growth with the industry, and pleasingly, we found that the growth seen by the company is higher than the average industry growth of 13%.

Earnings growth is a huge factor in stock valuation. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await.
