Why Diploma PLC (LON:DPLM) Looks Like A Quality Company

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 Diploma PLC (LON:DPLM).

Over the last twelve months Diploma has recorded a ROE of 18%. Another way to think of that is that for every £1 worth of equity in the company, it was able to earn £0.18.

How Do You Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Diploma:

18% = 53.8 ÷ UK£294m (Based on the trailing twelve months to September 2018.)

Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.

What Does Return On Equity Signify?

ROE measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

Does Diploma Have A Good ROE?

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. As you can see in the graphic below, Diploma has a higher ROE than the average (15%) in the trade distributors industry.

That’s what I like to see. I usually take a closer look when a company has a better ROE than industry peers. One data point to check is if insiders have bought shares recently.

How Does Debt Impact Return On Equity?

Most companies need money — from somewhere — to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders’ equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Diploma’s Debt And Its 18% ROE

One positive for shareholders is that Diploma does not have any net debt! Its ROE already suggests it is a good business, but the fact it has achieved this — and doesn’t borrowings — makes it worthy of further consideration, in my view. After all, when a company has a strong balance sheet, it can often find ways to invest in growth, even if it takes some time.

The Bottom Line On ROE

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have around the same level of debt to equity, and one has a higher ROE, I’d generally prefer the one with higher ROE.

But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth — and how much investment is required going forward.
