A Closer Look At Spark New Zealand Limited's (NZSE:SPK) Impressive ROE

·4 mins read

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. To keep the lesson grounded in practicality, we'll use ROE to better understand Spark New Zealand Limited (NZSE:SPK).

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

View our latest analysis for Spark New Zealand

How Is ROE Calculated?

The formula for return on equity is:

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

So, based on the above formula, the ROE for Spark New Zealand is:

30% = NZ$423m ÷ NZ$1.4b (Based on the trailing twelve months to December 2019).

The 'return' is the amount earned after tax over the last twelve months. That means that for every NZ$1 worth of shareholders' equity, the company generated NZ$0.30 in profit.

Does Spark New Zealand Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, Spark New Zealand has a superior ROE than the average (11%) in the Telecom industry.

That is a good sign. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Combining Spark New Zealand's Debt And Its 30% Return On Equity

Spark New Zealand does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.20. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In our books, the highest quality companies have high return on equity, despite low debt. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
