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 might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. Importantly, PTC Inc. (NASDAQ:PTC) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does PTC Carry?

As you can see below, PTC had US$1.75b of debt, at September 2024, which is about the same as the year before. You can click the chart for greater detail. However, it also had US$265.8m in cash, and so its net debt is US$1.48b.

How Healthy Is PTC's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that PTC had liabilities of US$1.67b due within 12 months and liabilities of US$1.50b due beyond that. Offsetting these obligations, it had cash of US$265.8m as well as receivables valued at US$876.4m due within 12 months. So it has liabilities totalling US$2.03b more than its cash and near-term receivables, combined.

Given PTC has a humongous market capitalization of US$24.0b, it's hard to believe these liabilities pose much threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

PTC has net debt worth 2.2 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 5.1 times the interest expense. While these numbers do not alarm us, it's worth noting that the cost of the company's debt is having a real impact. We note that PTC grew its EBIT by 24% in the last year, and that should make it easier to pay down debt, going forward. 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 PTC's ability to maintain a healthy balance sheet going forward.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the last three years, PTC actually produced more free cash flow than EBIT. That sort of strong cash conversion gets us as excited as the crowd when the beat drops at a Daft Punk concert.

Our View

Happily, PTC's impressive conversion of EBIT to free cash flow implies it has the upper hand on its debt. And the good news does not stop there, as its EBIT growth rate also supports that impression! Zooming out, PTC seems to use debt quite reasonably; and that gets the nod from us. While debt does bring risk, when used wisely it can also bring a higher return on equity. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. For instance, we've identified 1 warning sign for PTC that 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.
