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 COSOL is:

19% = AU$8.0m ÷ AU$43m (Based on the trailing twelve months to June 2023).

The 'return' refers to a company's earnings over the last year. So, this means that for every A$1 of its shareholder's investments, the company generates a profit of A$0.19.

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. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don’t share these attributes.

COSOL's Earnings Growth And 19% ROE

To begin with, COSOL seems to have a respectable ROE. On comparing with the average industry ROE of 11% the company's ROE looks pretty remarkable. This certainly adds some context to COSOL's exceptional 32% net income growth seen over the past five years. We reckon that there could also be other factors at play here. For instance, the company has a low payout ratio or is being managed efficiently.

Next, on comparing with the industry net income growth, we found that COSOL's growth is quite high when compared to the industry average growth of 21% in the same period, which is great to see.

Earnings growth is an important metric to consider when valuing a stock. 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 COS fairly valued? This infographic on the company's intrinsic value has everything you need to know.
