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.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. We note that Zebra Technologies Corporation (NASDAQ:ZBRA) does have debt on its balance sheet. But should shareholders be worried about its use of debt?

When Is Debt A Problem?

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 frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. 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.

What Is Zebra Technologies's Debt?

You can click the graphic below for the historical numbers, but it shows that Zebra Technologies had US$2.17b of debt in September 2024, down from US$2.31b, one year before. However, because it has a cash reserve of US$676.0m, its net debt is less, at about US$1.49b.

How Healthy Is Zebra Technologies' Balance Sheet?

The latest balance sheet data shows that Zebra Technologies had liabilities of US$1.56b due within a year, and liabilities of US$2.71b falling due after that. Offsetting this, it had US$676.0m in cash and US$709.0m in receivables that were due within 12 months. So its liabilities total US$2.88b more than the combination of its cash and short-term receivables.

Given Zebra Technologies has a humongous market capitalization of US$20.1b, 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). 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).

Zebra Technologies has net debt worth 1.9 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 4.7 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. The bad news is that Zebra Technologies saw its EBIT decline by 18% over the last year. If earnings continue to decline at that rate then handling the debt will be more difficult than taking three children under 5 to a fancy pants restaurant. 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 Zebra Technologies can strengthen its balance sheet over time.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Zebra Technologies recorded free cash flow worth 52% 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

Zebra Technologies's struggle to grow its EBIT had us second guessing its balance sheet strength, but the other data-points we considered were relatively redeeming. For example, its conversion of EBIT to free cash flow is relatively strong. Looking at all the angles mentioned above, it does seem to us that Zebra Technologies is a somewhat risky investment as a result of its debt. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it. For example - Zebra Technologies has 2 warning signs we think you should be aware of.

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.
