Iridium Communications (NASDAQ:IRDM) Has A Pretty Healthy Balance Sheet

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. As with many other companies Iridium Communications Inc. (NASDAQ:IRDM) makes use of debt. But the real question is whether this debt is making the company risky.

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. 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. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. 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 Debt?

The chart below, which you can click on for greater detail, shows that Iridium Communications had US$1.48b in debt in December 2023; about the same as the year before. However, it does have US$71.9m in cash offsetting this, leading to net debt of about US$1.41b.

How Strong Is Iridium Communications' Balance Sheet?

According to the last reported balance sheet, Iridium Communications had liabilities of US$131.6m due within 12 months, and liabilities of US$1.64b due beyond 12 months. Offsetting this, it had US$71.9m in cash and US$91.7m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.61b.

This deficit isn't so bad because Iridium Communications is worth US$3.16b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

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). 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 Iridium Communications's debt to EBITDA ratio (3.5) suggests that it uses some debt, its interest cover is very weak, at 1.3, suggesting high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Looking on the bright side, Iridium Communications boosted its EBIT by a silky 55% in the last year. Like a mother's loving embrace of a newborn that sort of growth builds resilience, putting the company in a stronger position to manage its debt. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine Iridium Communications's ability to maintain a healthy balance sheet going forward. 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 we clearly need to look at whether that EBIT is leading to corresponding 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

Iridium Communications's conversion of EBIT to free cash flow was a real positive on this analysis, as was its EBIT growth rate. In contrast, our confidence was undermined by its apparent struggle to cover its interest expense with its EBIT. Considering this range of data points, we think Iridium Communications 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. 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 example Iridium Communications has 3 warning signs (and 1 which is a bit concerning) we think you should know about.
