David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the 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. We can see that Digi International Inc. (NASDAQ:DGII) does use debt in its business. But is this debt a concern to shareholders?

When Is Debt A Problem?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. Of course, plenty of companies use debt to fund growth, without any negative consequences. 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 Digi International Carry?

The image below, which you can click on for greater detail, shows that Digi International had debt of US$95.0m at the end of December 2024, a reduction from US$194.7m over a year. However, it also had US$25.9m in cash, and so its net debt is US$69.0m.

A Look At Digi International's Liabilities

According to the last reported balance sheet, Digi International had liabilities of US$90.3m due within 12 months, and liabilities of US$115.1m due beyond 12 months. Offsetting this, it had US$25.9m in cash and US$64.9m in receivables that were due within 12 months. So its liabilities total US$114.6m more than the combination of its cash and short-term receivables.

Since publicly traded Digi International shares are worth a total of US$1.07b, it seems unlikely that this level of liabilities would be a major threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Looking at its net debt to EBITDA of 0.83 and interest cover of 4.1 times, it seems to us that Digi International is probably using debt in a pretty reasonable way. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. Notably Digi International's EBIT was pretty flat over the last year. Ideally it can diminish its debt load by kick-starting earnings growth. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Digi International can strengthen its balance sheet over time. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Happily for any shareholders, Digi International actually produced more free cash flow than EBIT over the last three years. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.

Our View

Happily, Digi International's impressive conversion of EBIT to free cash flow implies it has the upper hand on its debt. But, on a more sombre note, we are a little concerned by its interest cover. When we consider the range of factors above, it looks like Digi International is pretty sensible with its use of debt. That means they are taking on a bit more risk, in the hope of boosting shareholder returns. Of course, we wouldn't say no to the extra confidence that we'd gain if we knew that Digi International insiders have been buying shares: if you're on the same wavelength, you can find out if insiders are buying by clicking this link.
