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.' 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. As with many other companies Novanta Inc. (NASDAQ:NOVT) makes use of debt. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

How Much Debt Does Novanta Carry?

You can click the graphic below for the historical numbers, but it shows that as of June 2024 Novanta had US$481.9m of debt, an increase on US$408.5m, over one year. However, it does have US$98.5m in cash offsetting this, leading to net debt of about US$383.5m.

How Healthy Is Novanta's Balance Sheet?

We can see from the most recent balance sheet that Novanta had liabilities of US$153.5m falling due within a year, and liabilities of US$543.1m due beyond that. On the other hand, it had cash of US$98.5m and US$145.0m worth of receivables due within a year. So its liabilities total US$453.1m more than the combination of its cash and short-term receivables.

Of course, Novanta has a market capitalization of US$6.58b, so these liabilities are probably manageable. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Novanta has net debt worth 2.4 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 3.8 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. Unfortunately, Novanta saw its EBIT slide 8.1% in the last twelve months. If that earnings trend continues then its debt load will grow heavy like the heart of a polar bear watching its sole cub. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Novanta can strengthen its balance sheet over time.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the last three years, Novanta recorded free cash flow worth a fulsome 80% of its EBIT, which is stronger than we'd usually expect. That puts it in a very strong position to pay down debt.

Our View

When it comes to the balance sheet, the standout positive for Novanta was the fact that it seems able to convert EBIT to free cash flow confidently. However, our other observations weren't so heartening. For instance it seems like it has to struggle a bit to grow its EBIT. Considering this range of data points, we think Novanta is in a good position to manage its debt levels. 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.
