Specifically, we decided to study Protagonist Therapeutics'  ROE in this article.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

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 Protagonist Therapeutics is:

8.2% = US$56m ÷ US$689m (Based on the trailing twelve months to March 2025).

The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.08 in profit.

What Is The Relationship Between ROE And 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.

Protagonist Therapeutics' Earnings Growth And 8.2% ROE

On the face of it, Protagonist Therapeutics' ROE is not much to talk about. A quick further study shows that the company's ROE doesn't compare favorably to the industry average of 18% either. Despite this, surprisingly, Protagonist Therapeutics saw an exceptional 40% net income growth over the past five years. Therefore, there could be other reasons 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.
