Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We note that Flex Ltd. (NASDAQ:FLEX) does have debt on its balance sheet. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

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. If things get really bad, the lenders can take control of the business. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first step when considering a company's debt levels is to consider its cash and debt together.

How Much Debt Does Flex Carry?

The image below, which you can click on for greater detail, shows that Flex had debt of US$3.26b at the end of March 2024, a reduction from US$3.69b over a year. However, it also had US$2.47b in cash, and so its net debt is US$787.0m.

How Strong Is Flex's Balance Sheet?

The latest balance sheet data shows that Flex had liabilities of US$8.54b due within a year, and liabilities of US$4.39b falling due after that. On the other hand, it had cash of US$2.47b and US$3.28b worth of receivables due within a year. So it has liabilities totalling US$7.18b more than its cash and near-term receivables, combined.

This deficit is considerable relative to its very significant market capitalization of US$11.9b, so it does suggest shareholders should keep an eye on Flex's use of debt. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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).

Looking at its net debt to EBITDA of 0.51 and interest cover of 6.8 times, it seems to us that Flex is probably using debt in a pretty reasonable way. So we'd recommend keeping a close eye on the impact financing costs are having on the business. Flex's EBIT was pretty flat over the last year, but that shouldn't be an issue given the it doesn't have a lot of debt. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine Flex'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 the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. During the last three years, Flex produced sturdy free cash flow equating to 57% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.

Our View

On our analysis Flex's net debt to EBITDA should signal that it won't have too much trouble with its debt. But the other factors we noted above weren't so encouraging. For example, its level of total liabilities makes us a little nervous about its debt. When we consider all the factors mentioned above, we do feel a bit cautious about Flex's use of debt. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. For example - Flex has 2 warning signs we think you should be aware of.

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
