How Do You Calculate Return On Equity?

Return on equity can be calculated by using the formula:

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

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

16% = AU$103m ÷ AU$659m (Based on the trailing twelve months to June 2024).

The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each A$1 of shareholders' capital it has, the company made A$0.16 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.

ARB's Earnings Growth And 16% ROE

To begin with, ARB seems to have a respectable ROE. On comparing with the average industry ROE of 12% the company's ROE looks pretty remarkable. This certainly adds some context to ARB's decent 10% net income growth seen over the past five years.

We then compared ARB's net income growth with the industry and found that the company's growth figure is lower than the average industry growth rate of 16% in the same 5-year period, which is a bit concerning.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. This then helps them determine if the stock is placed for a bright or bleak future. Is ARB fairly valued compared to other companies? These 3 valuation measures might help you decide.
