Legendary fund manager Li Lu (who Charlie Munger backed) once said, 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. As with many other companies Nova Ltd. (NASDAQ:NVMI) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Nova Carry?

As you can see below, Nova had US$197.7m of debt, at December 2023, which is about the same as the year before. You can click the chart for greater detail. But on the other hand it also has US$443.7m in cash, leading to a US$246.0m net cash position.

How Healthy Is Nova's Balance Sheet?

The latest balance sheet data shows that Nova had liabilities of US$322.8m due within a year, and liabilities of US$60.2m falling due after that. Offsetting this, it had US$443.7m in cash and US$111.9m in receivables that were due within 12 months. So it can boast US$172.5m more liquid assets than total liabilities.

This short term liquidity is a sign that Nova could probably pay off its debt with ease, as its balance sheet is far from stretched. Succinctly put, Nova boasts net cash, so it's fair to say it does not have a heavy debt load!

On the other hand, Nova's EBIT dived 12%, over the last year. We think hat kind of performance, if repeated frequently, could well lead to difficulties for the stock. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Nova'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. 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 84% 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 it is always sensible to investigate a company's debt, in this case Nova has US$246.0m in net cash and a decent-looking balance sheet. And it impressed us with free cash flow of US$106m, being 84% of its EBIT. So we don't think Nova's use of debt is risky. Above most other metrics, we think its important to track how fast earnings per share is growing, if at all. If you've also come to that realization, you're in luck, because today you can view this interactive graph of Nova's earnings per share history for free.
