Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 Littelfuse, Inc. (NASDAQ:LFUS) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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 Littelfuse's Debt?

As you can see below, Littelfuse had US$866.7m of debt at March 2024, down from US$1.00b a year prior. On the flip side, it has US$566.3m in cash leading to net debt of about US$300.3m.

How Strong Is Littelfuse's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Littelfuse had liabilities of US$405.0m due within 12 months and liabilities of US$1.07b due beyond that. On the other hand, it had cash of US$566.3m and US$295.9m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$610.0m.

Given Littelfuse has a market capitalization of US$6.50b, 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.

Littelfuse has net debt of just 0.66 times EBITDA, indicating that it is certainly not a reckless borrower. And it boasts interest cover of 8.1 times, which is more than adequate. The modesty of its debt load may become crucial for Littelfuse if management cannot prevent a repeat of the 35% cut to EBIT over the last year. When a company sees its earnings tank, it can sometimes find its relationships with its lenders turn sour. 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 Littelfuse can strengthen its balance sheet over time.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. 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, Littelfuse recorded free cash flow worth 76% 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

Littelfuse'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 Littelfuse is managing its debt quite well. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. 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. Be aware that Littelfuse is showing 2 warning signs in our investment analysis , you should know about...
