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 Auckland International Airport is:
1.1% = NZ$88m ÷ NZ$8.2b (Based on the trailing twelve months to December 2022).
The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each NZ$1 of shareholders' capital it has, the company made NZ$0.01 in profit.
Why Is ROE Important For Earnings Growth?
Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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.
Auckland International Airport's Earnings Growth And 1.1% ROE
It is hard to argue that Auckland International Airport's ROE is much good in and of itself. Not just that, even compared to the industry average of 5.6%, the company's ROE is entirely unremarkable. For this reason, Auckland International Airport's five year net income decline of 19% is not surprising given its lower ROE. We reckon that there could also be other factors at play here. For example, the business has allocated capital poorly, or that the company has a very high payout ratio.
So, as a next step, we compared Auckland International Airport's performance against the industry and were disappointed to discover that while the company has been shrinking its earnings, the industry has been growing its earnings at a rate of 5.9% in the same period.
Earnings growth is an important metric to consider when valuing a stock. It’s important for an investor to know whether the market has priced in the company's expected earnings growth (or decline).
