The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. We note that Smiths Group plc (LON:SMIN) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?
When Is Debt A Problem?
Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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, plenty of companies use debt to fund growth, without any negative consequences. When we think about a company's use of debt, we first look at cash and debt together.
How Much Debt Does Smiths Group Carry?
As you can see below, Smiths Group had UK£559.0m of debt, at July 2025, which is about the same as the year before. You can click the chart for greater detail. However, because it has a cash reserve of UK£195.0m, its net debt is less, at about UK£364.0m.
A Look At Smiths Group's Liabilities
According to the last reported balance sheet, Smiths Group had liabilities of UK£941.0m due within 12 months, and liabilities of UK£1.01b due beyond 12 months. Offsetting this, it had UK£195.0m in cash and UK£721.0m in receivables that were due within 12 months. So it has liabilities totalling UK£1.04b more than its cash and near-term receivables, combined.
Of course, Smiths Group has a titanic market capitalization of UK£7.67b, 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.
View our latest analysis for Smiths Group
We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). 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).
Smiths Group has a low net debt to EBITDA ratio of only 0.68. And its EBIT covers its interest expense a whopping 16.3 times over. So you could argue it is no more threatened by its debt than an elephant is by a mouse. While Smiths Group doesn't seem to have gained much on the EBIT line, at least earnings remain stable for now. 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 Smiths Group'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 it's worth checking how much of that EBIT is backed by free cash flow. Over the most recent three years, Smiths Group recorded free cash flow worth 70% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.
Our View
Smiths Group's interest cover suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. And that's just the beginning of the good news since its conversion of EBIT to free cash flow is also very heartening. Taking all this data into account, it seems to us that Smiths Group takes a pretty sensible approach to debt. While that brings some risk, it can also enhance returns for shareholders.
