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.' 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 note that Tennant Company (NYSE:TNC) does have debt on its balance sheet. But is this debt a concern to shareholders?

What Risk Does Debt Bring?

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. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. 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. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Tennant's Net Debt?

You can click the graphic below for the historical numbers, but it shows that Tennant had US$214.2m of debt in March 2024, down from US$301.8m, one year before. However, it does have US$89.9m in cash offsetting this, leading to net debt of about US$124.3m.

How Healthy Is Tennant's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Tennant had liabilities of US$260.4m due within 12 months and liabilities of US$275.4m due beyond that. Offsetting this, it had US$89.9m in cash and US$257.3m in receivables that were due within 12 months. So its liabilities total US$188.6m more than the combination of its cash and short-term receivables.

Since publicly traded Tennant shares are worth a total of US$1.86b, it seems unlikely that this level of liabilities would be a major threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

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). 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 0.64. And its EBIT easily covers its interest expense, being 11.8 times the size. So you could argue it is no more threatened by its debt than an elephant is by a mouse. On top of that, Tennant grew its EBIT by 32% over the last twelve months, and that growth will make it easier to handle its debt. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Tennant can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. In the last three years, Tennant's free cash flow amounted to 44% of its EBIT, less than we'd expect. That weak cash conversion makes it more difficult to handle indebtedness.

Our View

The good news is that Tennant's demonstrated ability to grow its EBIT delights us like a fluffy puppy does a toddler. And that's just the beginning of the good news since its interest cover is also very heartening. Zooming out, Tennant seems to use debt quite reasonably; and that gets the nod from us. After all, sensible leverage can boost returns on equity. There's no doubt that we learn most about debt from the balance sheet. But ultimately, every company can contain risks that exist outside of the balance sheet. We've identified 2 warning signs with Tennant (at least 1 which is concerning) , and understanding them should be part of your investment process.
