Does Ciena (NYSE:CIEN) Have A 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 Ciena Corporation (NYSE:CIEN) makes use of debt. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

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. 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, 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. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Ciena's Debt?

You can click the graphic below for the historical numbers, but it shows that as of April 2023 Ciena had US$1.56b of debt, an increase on US$1.07b, over one year. On the flip side, it has US$1.32b in cash leading to net debt of about US$243.4m.

How Healthy Is Ciena's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Ciena had liabilities of US$1.06b due within 12 months and liabilities of US$1.81b due beyond that. Offsetting this, it had US$1.32b in cash and US$1.26b in receivables that were due within 12 months. So its liabilities total US$290.9m more than the combination of its cash and short-term receivables.

Since publicly traded Ciena shares are worth a total of US$6.28b, it seems unlikely that this level of liabilities would be a major threat. 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). 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).

With net debt sitting at just 0.52 times EBITDA, Ciena is arguably pretty conservatively geared. And it boasts interest cover of 8.1 times, which is more than adequate. In fact Ciena's saving grace is its low debt levels, because its EBIT has tanked 24% in the last twelve months. When a company sees its earnings tank, it can sometimes find its relationships with its lenders turn sour. 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 Ciena's ability to maintain a healthy balance sheet going forward.

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. Looking at the most recent three years, Ciena recorded free cash flow of 35% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

Ciena's EBIT growth rate was a real negative on this analysis, although the other factors we considered cast it in a significantly better light. In particular, its net debt to EBITDA was re-invigorating. We think that Ciena's debt does make it a bit risky, after considering the aforementioned data points together. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. When analysing debt levels, the balance sheet is the obvious place to start. 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 2 warning signs for Ciena (of which 1 is a bit unpleasant!) you should know about.

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
