Warren Buffett famously said, 'Volatility is far from synonymous with risk.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We can see that Iridium Communications Inc. (NASDAQ:IRDM) does use debt in its business. But the real question is whether this debt is making the company risky.

When Is Debt Dangerous?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. 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.

What Is Iridium Communications's Net Debt?

As you can see below, at the end of March 2024, Iridium Communications had US$1.60b of debt, up from US$1.48b a year ago. Click the image for more detail. On the flip side, it has US$174.0m in cash leading to net debt of about US$1.43b.

A Look At Iridium Communications' Liabilities

According to the last reported balance sheet, Iridium Communications had liabilities of US$113.0m due within 12 months, and liabilities of US$1.77b due beyond 12 months. Offsetting this, it had US$174.0m in cash and US$93.0m in receivables that were due within 12 months. So its liabilities total US$1.62b more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Iridium Communications has a market capitalization of US$3.15b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While Iridium Communications's debt to EBITDA ratio (3.6) suggests that it uses some debt, its interest cover is very weak, at 1.6, suggesting high leverage. It seems that the business incurs large depreciation and amortisation charges, so maybe its debt load is heavier than it would first appear, since EBITDA is arguably a generous measure of earnings. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. Looking on the bright side, Iridium Communications boosted its EBIT by a silky 81% in the last year. Like the milk of human kindness that sort of growth increases resilience, making the company more capable of managing debt. 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 Iridium Communications can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Happily for any shareholders, Iridium Communications actually produced more free cash flow than EBIT over the last three years. That sort of strong cash conversion gets us as excited as the crowd when the beat drops at a Daft Punk concert.

Our View

The good news is that Iridium Communications's demonstrated ability to convert EBIT to free cash flow delights us like a fluffy puppy does a toddler. But we must concede we find its interest cover has the opposite effect. Looking at all the aforementioned factors together, it strikes us that Iridium Communications can handle its debt fairly comfortably. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one. 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. These risks can be hard to spot. Every company has them, and we've spotted 3 warning signs for Iridium Communications (of which 1 makes us a bit uncomfortable!) you should know about.
