Is Ciena (NYSE:CIEN) 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.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. As with many other companies Ciena Corporation (NYSE:CIEN) makes use of debt. But should shareholders be worried about its use of debt?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. 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.

How Much Debt Does Ciena Carry?

As you can see below, Ciena had US$1.55b of debt, at July 2024, which is about the same as the year before. You can click the chart for greater detail. However, it does have US$1.10b in cash offsetting this, leading to net debt of about US$448.8m.

How Healthy Is Ciena's Balance Sheet?

We can see from the most recent balance sheet that Ciena had liabilities of US$870.6m falling due within a year, and liabilities of US$1.81b due beyond that. Offsetting these obligations, it had cash of US$1.10b as well as receivables valued at US$1.09b due within 12 months. So its liabilities total US$498.0m more than the combination of its cash and short-term receivables.

Of course, Ciena has a market capitalization of US$9.13b, so these liabilities are probably manageable. 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.

While Ciena's low debt to EBITDA ratio of 1.2 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 6.5 times last year does give us pause. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. The modesty of its debt load may become crucial for Ciena if management cannot prevent a repeat of the 39% cut to EBIT over the last year. Falling earnings (if the trend continues) could eventually make even modest debt quite risky. 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 Ciena's ability to maintain a healthy balance sheet going forward. 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 the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. In the last three years, Ciena created free cash flow amounting to 18% of its EBIT, an uninspiring performance. That limp level of cash conversion undermines its ability to manage and pay down debt.

Our View

Ciena's struggle to grow its EBIT had us second guessing its balance sheet strength, but the other data-points we considered were relatively redeeming. But on the bright side, its ability to handle its debt, based on its EBITDA, isn't too shabby at all. When we consider all the factors discussed, it seems to us that Ciena is taking some risks with its use of debt. While that debt can boost returns, we think the company has enough leverage now. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. To that end, you should be aware of the 2 warning signs we've spotted with Ciena .
