20% = US$184m ÷ US$928m (Based on the trailing twelve months to December 2024).

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 $0.20 in profit.

What Has ROE Got To Do With 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 everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.
