Diploma (LON:DPLM) Seems To Use Debt Rather Sparingly

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.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. Importantly, Diploma PLC (LON:DPLM) does carry debt.

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, plenty of companies use debt to fund growth, without any negative consequences. The first thing to do when considering how much debt a business uses is to look at its cash and debt together. What Is Diploma's Net Debt? As you can see below, Diploma had UK£381.1m of debt at September 2025, down from UK£479.8m a year prior. However, it does have UK£81.7m in cash offsetting this, leading to net debt of about UK£299.4m. LSE:DPLM Debt to Equity History December 19th 2025 A Look At Diploma's Liabilities Zooming in on the latest balance sheet data, we can see that Diploma had liabilities of UK£298.3m due within 12 months and liabilities of UK£516.9m due beyond that. On the other hand, it had cash of UK£81.7m and UK£218.3m worth of receivables due within a year. So its liabilities total UK£515.2m more than the combination of its cash and short-term receivables. Since publicly traded Diploma shares are worth a total of UK£7.17b, it seems unlikely that this level of liabilities would be a major threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse. Check out our latest analysis for Diploma 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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it. With net debt sitting at just 0.85 times EBITDA, Diploma is arguably pretty conservatively geared. And it boasts interest cover of 9.7 times, which is more than adequate. Another good sign is that Diploma has been able to increase its EBIT by 23% in twelve months, making it easier to pay down debt. When analysing debt levels, the balance sheet is the obvious place to start. 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 company can only pay off debt with cold hard cash, not accounting profits. So it's worth checking how much of that EBIT is backed by free cash flow. During the last three years, Diploma generated free cash flow amounting to a very robust 86% of its EBIT, more than we'd expect. That puts it in a very strong position to pay down debt. Our View The good news is that Diploma's demonstrated ability to convert EBIT to free cash flow delights us like a fluffy puppy does a toddler. 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.
