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.' 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 can see that Qiagen N.V. (NYSE:QGEN) does use debt in its business. But is this debt a concern to shareholders?

When Is Debt Dangerous?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. 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 step when considering a company's debt levels is to consider its cash and debt together.

What Is Qiagen's Debt?

The image below, which you can click on for greater detail, shows that Qiagen had debt of US$1.61b at the end of December 2023, a reduction from US$1.90b over a year. On the flip side, it has US$1.06b in cash leading to net debt of about US$550.9m.

How Strong Is Qiagen's Balance Sheet?

The latest balance sheet data shows that Qiagen had liabilities of US$1.08b due within a year, and liabilities of US$1.23b falling due after that. Offsetting this, it had US$1.06b in cash and US$495.7m in receivables that were due within 12 months. So its liabilities total US$753.9m more than the combination of its cash and short-term receivables.

Of course, Qiagen has a market capitalization of US$9.74b, 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.

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.

Qiagen has a low debt to EBITDA ratio of only 0.86. But the really cool thing is that it actually managed to receive more interest than it paid, over the last year. So it's fair to say it can handle debt like a hotshot teppanyaki chef handles cooking. It is just as well that Qiagen's load is not too heavy, because its EBIT was down 23% over the last year. Falling earnings (if the trend continues) could eventually make even modest debt quite risky. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Qiagen's ability to maintain a healthy balance sheet going forward.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Qiagen produced sturdy free cash flow equating to 77% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.

Our View

The good news is that Qiagen's demonstrated ability to cover its interest expense with its EBIT delights us like a fluffy puppy does a toddler. But the stark truth is that we are concerned by its EBIT growth rate. Looking at all the aforementioned factors together, it strikes us that Qiagen can handle its debt fairly comfortably. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one. We'd be motivated to research the stock further if we found out that Qiagen insiders have bought shares recently.
