Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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. We note that Coeur Mining, Inc. (NYSE:CDE) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

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. If things get really bad, the lenders can take control of the business. 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. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth 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 Coeur Mining's Net Debt?

As you can see below, at the end of June 2022, Coeur Mining had US$483.7m of debt, up from US$367.8m a year ago. Click the image for more detail. However, it also had US$161.7m in cash, and so its net debt is US$322.0m.

How Healthy Is Coeur Mining's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Coeur Mining had liabilities of US$241.1m due within 12 months and liabilities of US$762.1m due beyond that. On the other hand, it had cash of US$161.7m and US$32.5m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$809.0m.

Given this deficit is actually higher than the company's market capitalization of US$758.3m, we think shareholders really should watch Coeur Mining's debt levels, like a parent watching their child ride a bike for the first time. In the scenario where the company had to clean up its balance sheet quickly, it seems likely shareholders would suffer extensive dilution.

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). 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 Coeur Mining has a quite reasonable net debt to EBITDA multiple of 2.1, its interest cover seems weak, at 1.3. In large part that's it has so much depreciation and amortisation. These charges may be non-cash, so they could be excluded when it comes to paying down debt. But the accounting charges are there for a reason -- some assets are seen to be losing value. Either way there's no doubt the stock is using meaningful leverage. Shareholders should be aware that Coeur Mining's EBIT was down 86% last year. If that decline continues then paying off debt will be harder than selling foie gras at a vegan convention. 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 Coeur Mining's ability to maintain a healthy balance sheet going forward.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. Over the last two years, Coeur Mining saw substantial negative free cash flow, in total. While investors are no doubt expecting a reversal of that situation in due course, it clearly does mean its use of debt is more risky.

Our View

To be frank both Coeur Mining's conversion of EBIT to free cash flow and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. Having said that, its ability handle its debt, based on its EBITDA, isn't such a worry. After considering the datapoints discussed, we think Coeur Mining has too much debt. That sort of riskiness is ok for some, but it certainly doesn't float our boat. 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.
