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 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 note that Zumtobel Group AG (VIE:ZAG) does have debt on its balance sheet. But should shareholders be worried about its use of debt?
Why Does Debt Bring Risk?
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. If things get really bad, the lenders can take control of the business. 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, debt can be an important tool in businesses, particularly capital heavy businesses. The first step when considering a company's debt levels is to consider its cash and debt together.
What Is Zumtobel Group's Debt?
The image below, which you can click on for greater detail, shows that at July 2025 Zumtobel Group had debt of €184.0m, up from €154.7m in one year. However, it also had €50.9m in cash, and so its net debt is €133.1m.
A Look At Zumtobel Group's Liabilities
According to the last reported balance sheet, Zumtobel Group had liabilities of €303.7m due within 12 months, and liabilities of €277.1m due beyond 12 months. Offsetting this, it had €50.9m in cash and €158.5m in receivables that were due within 12 months. So it has liabilities totalling €371.5m more than its cash and near-term receivables, combined.
The deficiency here weighs heavily on the €142.3m company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we'd watch its balance sheet closely, without a doubt. After all, Zumtobel Group would likely require a major re-capitalisation if it had to pay its creditors today.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.
While we wouldn't worry about Zumtobel Group's net debt to EBITDA ratio of 3.3, we think its super-low interest cover of 1.1 times is a sign of high leverage. It seems that the business incurs large depreciation and amortisation charges, so maybe its debt load is heavier than it would first appear, since EBITDA is arguably a generous measure of earnings. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Worse, Zumtobel Group's EBIT was down 81% over the last year. If earnings continue to follow that trajectory, paying off that debt load will be harder than convincing us to run a marathon in the rain. 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 Zumtobel Group's ability to maintain a healthy balance sheet going forward. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.
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. During the last three years, Zumtobel Group generated free cash flow amounting to a very robust 94% of its EBIT, more than we'd expect. That positions it well to pay down debt if desirable to do so.
Our View
On the face of it, Zumtobel Group's EBIT growth rate left us tentative about the stock, and its level of total liabilities was no more enticing than the one empty restaurant on the busiest night of the year. But on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. Overall, it seems to us that Zumtobel Group's balance sheet is really quite a risk to the business. So we're almost as wary of this stock as a hungry kitten is about falling into its owner's fish pond: once bitten, twice shy, as they say. 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. These risks can be hard to spot. Every company has them, and we've spotted 1 warning sign for Zumtobel Group you should know about.
