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 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. We can see that ACEA S.p.A. (BIT:ACE) does use debt in its business. But the real question is whether this debt is making the company risky.
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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we think about a company's use of debt, we first look at cash and debt together.
As you can see below, ACEA had €5.68b of debt, at September 2025, which is about the same as the year before. You can click the chart for greater detail. However, it does have €524.3m in cash offsetting this, leading to net debt of about €5.16b.
We can see from the most recent balance sheet that ACEA had liabilities of €2.90b falling due within a year, and liabilities of €6.75b due beyond that. On the other hand, it had cash of €524.3m and €965.4m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by €8.16b.
This deficit casts a shadow over the €4.78b company, like a colossus towering over mere mortals. So we'd watch its balance sheet closely, without a doubt. At the end of the day, ACEA would probably need a major re-capitalization if its creditors were to demand repayment.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.
ACEA has a debt to EBITDA ratio of 4.4, which signals significant debt, but is still pretty reasonable for most types of business. However, its interest coverage of 45.0 is very high, suggesting that the interest expense on the debt is currently quite low. ACEA grew its EBIT by 6.3% in the last year. Whilst that hardly knocks our socks off it is a positive when it comes to 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 ACEA'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 it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, ACEA reported free cash flow worth 12% of its EBIT, which is really quite low. That limp level of cash conversion undermines its ability to manage and pay down debt.
Mulling over ACEA's attempt at staying on top of its total liabilities, we're certainly not enthusiastic. But at least it's pretty decent at covering its interest expense with its EBIT; that's encouraging. We should also note that Integrated Utilities industry companies like ACEA commonly do use debt without problems. Overall, we think it's fair to say that ACEA has enough debt that there are some real risks around the balance sheet. If everything goes well that may pay off but the downside of this debt is a greater risk of permanent losses. 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 2 warning signs for ACEA (of which 1 is a bit concerning!) you should know about.
