Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. As with many other companies Capstone Copper Corp. (TSE:CS) makes use of debt. But is this debt a concern to shareholders?
When Is Debt Dangerous?
Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. 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. 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.
How Much Debt Does Capstone Copper Carry?
As you can see below, at the end of March 2025, Capstone Copper had US$1.46b of debt, up from US$1.07b a year ago. Click the image for more detail. However, because it has a cash reserve of US$351.9m, its net debt is less, at about US$1.10b.
How Strong Is Capstone Copper's Balance Sheet?
The latest balance sheet data shows that Capstone Copper had liabilities of US$701.0m due within a year, and liabilities of US$2.47b falling due after that. Offsetting this, it had US$351.9m in cash and US$222.1m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$2.60b.
This deficit isn't so bad because Capstone Copper is worth US$4.33b, 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.
View our latest analysis for Capstone Copper
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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.
Capstone Copper has a debt to EBITDA ratio of 2.5 and its EBIT covered its interest expense 3.7 times. This suggests that while the debt levels are significant, we'd stop short of calling them problematic. Pleasingly, Capstone Copper is growing its EBIT faster than former Australian PM Bob Hawke downs a yard glass, boasting a 594% gain in the last twelve months. 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 Capstone Copper can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.
Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Capstone Copper burned a lot of cash. 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
Capstone Copper's conversion of EBIT to free cash flow and interest cover definitely weigh on it, in our esteem. But the good news is it seems to be able to grow its EBIT with ease. When we consider all the factors discussed, it seems to us that Capstone Copper 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. 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. These risks can be hard to spot. Every company has them, and we've spotted 1 warning sign for Capstone Copper you should know about.
