Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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. Importantly, Nova Ltd. (NASDAQ:NVMI) does carry debt. But is this debt a concern to shareholders?

What Risk Does Debt Bring?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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. 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 Nova's Net Debt?

The chart below, which you can click on for greater detail, shows that Nova had US$198.3m in debt in June 2024; about the same as the year before. However, its balance sheet shows it holds US$537.8m in cash, so it actually has US$339.5m net cash.

How Healthy Is Nova's Balance Sheet?

The latest balance sheet data shows that Nova had liabilities of US$346.4m due within a year, and liabilities of US$58.0m falling due after that. On the other hand, it had cash of US$537.8m and US$93.6m worth of receivables due within a year. So it can boast US$227.0m more liquid assets than total liabilities.

This surplus suggests that Nova has a conservative balance sheet, and could probably eliminate its debt without much difficulty. Succinctly put, Nova boasts net cash, so it's fair to say it does not have a heavy debt load!

Fortunately, Nova grew its EBIT by 5.1% in the last year, making that debt load look even more manageable. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Nova's ability to maintain a healthy balance sheet going forward.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. While Nova has net cash on its balance sheet, it's still worth taking a look at its ability to convert earnings before interest and tax (EBIT) to free cash flow, to help us understand how quickly it is building (or eroding) that cash balance. Over the last three years, Nova recorded free cash flow worth a fulsome 89% of its EBIT, which is stronger than we'd usually expect. That positions it well to pay down debt if desirable to do so.

Summing Up

While we empathize with investors who find debt concerning, you should keep in mind that Nova has net cash of US$339.5m, as well as more liquid assets than liabilities. And it impressed us with free cash flow of US$180m, being 89% of its EBIT. So is Nova's debt a risk? It doesn't seem so to us. 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. We've identified 1 warning sign with Nova , and understanding them should be part of your investment process.
