How Do You Calculate Return On Equity?

The formula for ROE is:

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

So, based on the above formula, the ROE for ACM Research is:

10% = US$97m ÷ US$926m (Based on the trailing twelve months to December 2023).

The 'return' is the amount earned after tax over the last twelve months. That means that for every $1 worth of shareholders' equity, the company generated $0.10 in profit.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company’s earnings growth potential. 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.

ACM Research's Earnings Growth And 10% ROE

To start with, ACM Research's ROE looks acceptable. Even so, when compared with the average industry ROE of 14%, we aren't very excited. Still, we can see that ACM Research has seen a remarkable net income growth of 38% over the past five years. We reckon that there could be other factors at play here. For instance, the company has a low payout ratio or is being managed efficiently.

So this certainly also provides some context to the high earnings growth seen by the company.

As a next step, we compared ACM Research'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 29%.
