Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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 Waters Corporation (NYSE:WAT) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.

What Risk Does Debt Bring?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Waters's Net Debt?

You can click the graphic below for the historical numbers, but it shows that Waters had US$1.85b of debt in September 2024, down from US$2.51b, one year before. However, because it has a cash reserve of US$331.5m, its net debt is less, at about US$1.52b.

How Strong Is Waters' Balance Sheet?

According to the last reported balance sheet, Waters had liabilities of US$816.0m due within 12 months, and liabilities of US$2.09b due beyond 12 months. Offsetting this, it had US$331.5m in cash and US$669.5m in receivables that were due within 12 months. So it has liabilities totalling US$1.91b more than its cash and near-term receivables, combined.

Since publicly traded Waters shares are worth a very impressive total of US$22.2b, 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.

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.

With a debt to EBITDA ratio of 1.5, Waters uses debt artfully but responsibly. And the alluring interest cover (EBIT of 9.7 times interest expense) certainly does not do anything to dispel this impression. On the other hand, Waters saw its EBIT drop by 7.2% in the last twelve months. If earnings continue to decline at that rate the company may have increasing difficulty managing its debt load. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Waters 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. During the last three years, Waters produced sturdy free cash flow equating to 58% 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 Waters's interest cover 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 EBIT growth rate makes us a little nervous about its debt. When we consider all the elements mentioned above, it seems to us that Waters is managing its debt quite well. But a word of caution: we think debt levels are high enough to justify ongoing monitoring. 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. For example, we've discovered 1 warning sign for Waters that you should be aware of before investing here.
