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 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. As with many other companies CDW Corporation (NASDAQ:CDW) makes use of debt. But should shareholders be worried about its use of debt?

Why Does Debt Bring Risk?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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, debt can be an important tool in businesses, particularly capital heavy businesses. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is CDW's Debt?

As you can see below, CDW had US$6.03b of debt at June 2024, down from US$6.38b a year prior. However, because it has a cash reserve of US$665.3m, its net debt is less, at about US$5.37b.

How Healthy Is CDW's Balance Sheet?

We can see from the most recent balance sheet that CDW had liabilities of US$6.21b falling due within a year, and liabilities of US$5.26b due beyond that. Offsetting this, it had US$665.3m in cash and US$5.36b in receivables that were due within 12 months. So its liabilities total US$5.44b more than the combination of its cash and short-term receivables.

Given CDW has a humongous market capitalization of US$29.6b, it's hard to believe these liabilities pose much threat. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

CDW has net debt to EBITDA of 2.7 suggesting it uses a fair bit of leverage to boost returns. On the plus side, its EBIT was 8.0 times its interest expense, and its net debt to EBITDA, was quite high, at 2.7. Importantly CDW's EBIT was essentially flat over the last twelve months. We would prefer to see some earnings growth, because that always helps diminish debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine CDW'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 it's worth checking how much of that EBIT is backed by free cash flow. During the last three years, CDW produced sturdy free cash flow equating to 70% 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 CDW's demonstrated ability to convert EBIT to free cash flow delights us like a fluffy puppy does a toddler. But truth be told we feel its net debt to EBITDA does undermine this impression a bit. Looking at all the aforementioned factors together, it strikes us that CDW can handle its debt fairly comfortably. On the plus side, this leverage can boost shareholder returns, but the potential downside is more risk of loss, so it's worth monitoring the balance sheet. 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.
