Is Diploma (LON:DPLM) Using Too Much Debt?

Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We can see that Diploma PLC (LON:DPLM) does use debt in its business. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Diploma's Debt?

You can click the graphic below for the historical numbers, but it shows that Diploma had UK£317.1m of debt in September 2023, down from UK£370.6m, one year before. On the flip side, it has UK£62.4m in cash leading to net debt of about UK£254.7m.

How Healthy Is Diploma's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Diploma had liabilities of UK£236.5m due within 12 months and liabilities of UK£450.8m due beyond that. Offsetting this, it had UK£62.4m in cash and UK£185.5m in receivables that were due within 12 months. So it has liabilities totalling UK£439.4m more than its cash and near-term receivables, combined.

Of course, Diploma has a market capitalization of UK£4.37b, so these liabilities are probably manageable. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). The advantage of this approach is that we take into account both the absolute quantum of debt (with net debt to EBITDA) and the actual interest expenses associated with that debt (with its interest cover ratio).

Diploma has net debt of just 0.97 times EBITDA, indicating that it is certainly not a reckless borrower. And this view is supported by the solid interest coverage, with EBIT coming in at 7.6 times the interest expense over the last year. Also positive, Diploma grew its EBIT by 27% in the last year, and that should make it easier to pay down debt, going forward. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine Diploma's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Diploma generated free cash flow amounting to a very robust 83% of its EBIT, more than we'd expect. That puts it in a very strong position to pay down debt.

Our View

Happily, Diploma's impressive conversion of EBIT to free cash flow implies it has the upper hand on its debt. And the good news does not stop there, as its EBIT growth rate also supports that impression! Considering this range of factors, it seems to us that Diploma is quite prudent with its debt, and the risks seem well managed. So the balance sheet looks pretty healthy, to us. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. To that end, you should be aware of the 2 warning signs we've spotted with Diploma .
