Mercury NZ (NZSE:MCY) has had a rough three months with its share price down 9.1%. We, however decided to study the company's financials to determine if they have got anything to do with the price decline. Long-term fundamentals are usually what drive market outcomes, so it's worth paying close attention. Particularly, we will be paying attention to Mercury NZ's  ROE today.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How To Calculate Return On Equity?

ROE 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 Mercury NZ is:

2.1% = NZ$103m ÷ NZ$4.8b (Based on the trailing twelve months to June 2023).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every NZ$1 worth of equity, the company was able to earn NZ$0.02 in profit.

What Is The Relationship Between ROE And Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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. 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.

A Side By Side comparison of Mercury NZ's Earnings Growth And 2.1% ROE

It is hard to argue that Mercury NZ's ROE is much good in and of itself. Not just that, even compared to the industry average of 8.0%, the company's ROE is entirely unremarkable. Hence, the flat earnings seen by Mercury NZ over the past five years could probably be the result of it having a lower ROE.



Next, on comparing with the industry net income growth, we found that Mercury NZ's growth figure is a bit better than the industry which has been shrinking at a rate of 1.2% in the same period. past-earnings-growth

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. Doing so will help them establish if the stock's future looks promising or ominous.

Is Mercury NZ Making Efficient Use Of Its Profits?

With a high three-year median payout ratio of 94% (implying that the company keeps only 6.4% of its income) of its business to reinvest into its business), most of Mercury NZ's profits are being paid to shareholders, which explains the absence of growth in earnings.

Additionally, Mercury NZ has paid dividends over a period of at least ten years, which means that the company's management is determined to pay dividends even if it means little to no earnings growth. Looking at the current analyst consensus data, we can see that the company's future payout ratio is expected to rise to 132% over the next three years. However, Mercury NZ's future ROE is expected to rise to 6.1% despite the expected increase in the company's payout ratio. We infer that there could be other factors that could be driving the anticipated growth in the company's ROE.

Summary

In total, we're a bit ambivalent about Mercury NZ's performance. While the company has posted impressive earnings growth, its poor ROE and low earnings retention makes us doubtful if that growth could continue, if by any chance the business is faced with any sort of risk. That being so, the latest analyst forecasts show that the company will continue to see an expansion in its earnings.
