Legendary fund manager Li Lu (who Charlie Munger backed) once said, 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. We can see that Tennant Company (NYSE:TNC) does use debt in its business. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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 think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Tennant Carry?

You can click the graphic below for the historical numbers, but it shows that Tennant had US$209.3m of debt in September 2024, down from US$221.5m, one year before. On the flip side, it has US$91.4m in cash leading to net debt of about US$117.9m.

How Healthy Is Tennant's Balance Sheet?

The latest balance sheet data shows that Tennant had liabilities of US$273.5m due within a year, and liabilities of US$294.1m falling due after that. On the other hand, it had cash of US$91.4m and US$260.2m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$216.0m.

Given Tennant has a market capitalization of US$1.62b, it's hard to believe these liabilities pose much threat. 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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Tennant has a low net debt to EBITDA ratio of only 0.63. And its EBIT easily covers its interest expense, being 13.4 times the size. So you could argue it is no more threatened by its debt than an elephant is by a mouse. On the other hand, Tennant saw its EBIT drop by 9.0% in the last twelve months. If earnings continue to decline at that rate the company may have increasing difficulty managing its debt load. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Tennant can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Looking at the most recent three years, Tennant recorded free cash flow of 41% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

On our analysis Tennant's interest cover should signal that it won't have too much trouble with its debt. However, our other observations weren't so heartening. For example, its EBIT growth rate makes us a little nervous about its debt. Considering this range of data points, we think Tennant is in a good position to manage its debt levels. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. Of course, we wouldn't say no to the extra confidence that we'd gain if we knew that Tennant insiders have been buying shares: if you're on the same wavelength, you can find out if insiders are buying by clicking this link.

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
