Is Iridium Communications (NASDAQ:IRDM) Using Too Much Debt?

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.' 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. As with many other companies Iridium Communications Inc. (NASDAQ:IRDM) 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. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Iridium Communications Carry?

The image below, which you can click on for greater detail, shows that Iridium Communications had debt of US$1.48b at the end of June 2023, a reduction from US$1.59b over a year. However, it also had US$103.5m in cash, and so its net debt is US$1.38b.

How Healthy Is Iridium Communications' Balance Sheet?

We can see from the most recent balance sheet that Iridium Communications had liabilities of US$124.2m falling due within a year, and liabilities of US$1.66b due beyond that. Offsetting these obligations, it had cash of US$103.5m as well as receivables valued at US$92.1m due within 12 months. So its liabilities total US$1.58b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because Iridium Communications is worth US$6.19b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. 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). The advantage of this approach is that we take into account both the absolute quantum of debt (with net debt to EBITDA) and the actual interest expenses associated with that debt (with its interest cover ratio).

While we wouldn't worry about Iridium Communications's net debt to EBITDA ratio of 3.9, we think its super-low interest cover of 0.61 times is a sign of 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. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Worse, Iridium Communications's EBIT was down 33% over the last year. If earnings keep going like that over the long term, it has a snowball's chance in hell of paying off that debt. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Iridium Communications 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 it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Iridium Communications actually produced more free cash flow than EBIT. There's nothing better than incoming cash when it comes to staying in your lenders' good graces.

Our View

Iridium Communications's EBIT growth rate and interest cover definitely weigh on it, in our esteem. But the good news is it seems to be able to convert EBIT to free cash flow with ease. When we consider all the factors discussed, it seems to us that Iridium Communications is taking some risks with its use of debt. So while that leverage does boost returns on equity, we wouldn't really want to see it increase from here. 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. Case in point: We've spotted 1 warning sign for Iridium Communications you should be aware of.
