How Is ROE Calculated?

The formula for ROE is:

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

So, based on the above formula, the ROE for Spirax-Sarco Engineering is:

19% = UK£211m ÷ UK£1.1b (Based on the trailing twelve months to June 2023).

The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each £1 of shareholders' capital it has, the company made £0.19 in profit.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. 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 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 Spirax-Sarco Engineering's Earnings Growth And 19% ROE

At first glance, Spirax-Sarco Engineering seems to have a decent ROE. Further, the company's ROE compares quite favorably to the industry average of 14%. Despite this, Spirax-Sarco Engineering's five year net income growth was quite low averaging at only 3.2%. This is generally not the case as when a company has a high rate of return it should usually also have a high earnings growth rate. Such a scenario is likely to take place when a company pays out a huge portion of its earnings as dividends, or is faced with competitive pressures.

As a next step, we compared Spirax-Sarco Engineering's net income growth with the industry and were disappointed to see that the company's growth is lower than the industry average growth of 7.1% in the same period.
