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 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 Analog Devices, Inc. (NASDAQ:ADI) makes use of debt. But is this debt a concern to shareholders?

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. If things get really bad, the lenders can take control of the business. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Analog Devices's Debt?

You can click the graphic below for the historical numbers, but it shows that as of November 2024 Analog Devices had US$7.62b of debt, an increase on US$7.03b, over one year. However, it does have US$2.36b in cash offsetting this, leading to net debt of about US$5.26b.

How Healthy Is Analog Devices' Balance Sheet?

We can see from the most recent balance sheet that Analog Devices had liabilities of US$2.99b falling due within a year, and liabilities of US$10.1b due beyond that. On the other hand, it had cash of US$2.36b and US$1.34b worth of receivables due within a year. So it has liabilities totalling US$9.35b more than its cash and near-term receivables, combined.

Since publicly traded Analog Devices shares are worth a very impressive total of US$108.2b, it seems unlikely that this level of liabilities would be a major threat. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

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).

Analog Devices has net debt of just 1.3 times EBITDA, indicating that it is certainly not a reckless borrower. And this view is supported by the solid interest coverage, with EBIT coming in at 8.5 times the interest expense over the last year. It is just as well that Analog Devices's load is not too heavy, because its EBIT was down 48% over the last year. When a company sees its earnings tank, it can sometimes find its relationships with its lenders turn sour. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Analog Devices can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. Happily for any shareholders, Analog Devices actually produced more free cash flow than EBIT over the last three years. There's nothing better than incoming cash when it comes to staying in your lenders' good graces.

Our View

Analog Devices's EBIT growth rate was a real negative on this analysis, although the other factors we considered were considerably better. In particular, we are dazzled with its conversion of EBIT to free cash flow. When we consider all the elements mentioned above, it seems to us that Analog Devices is managing its debt quite well. But a word of caution: we think debt levels are high enough to justify ongoing monitoring. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. We've identified 2 warning signs with Analog Devices , and understanding them should be part of your investment process.

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.
