Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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 note that EDP, S.A. (ELI:EDP) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?
Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. 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. 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. When we examine debt levels, we first consider both cash and debt levels, together.
The chart below, which you can click on for greater detail, shows that EDP had €22.2b in debt in September 2025; about the same as the year before. On the flip side, it has €1.86b in cash leading to net debt of about €20.3b.
The latest balance sheet data shows that EDP had liabilities of €10.1b due within a year, and liabilities of €27.4b falling due after that. Offsetting these obligations, it had cash of €1.86b as well as receivables valued at €4.84b due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by €30.8b.
This deficit casts a shadow over the €16.2b 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, EDP would probably need a major re-capitalization if its creditors were to demand repayment.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.
EDP shareholders face the double whammy of a high net debt to EBITDA ratio (5.3), and fairly weak interest coverage, since EBIT is just 2.2 times the interest expense. This means we'd consider it to have a heavy debt load. Worse, EDP's EBIT was down 34% over the last year. If earnings keep going like that over the long term, it has a snowball's chance in hell of paying off that debt. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if EDP 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.
But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the last three years, EDP 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.
To be frank both EDP's EBIT growth rate and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. And even its net debt to EBITDA fails to inspire much confidence. We should also note that Electric Utilities industry companies like EDP commonly do use debt without problems. It looks to us like EDP carries a significant balance sheet burden. If you harvest honey without a bee suit, you risk getting stung, so we'd probably stay away from this particular stock. 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. Case in point: We've spotted 3 warning signs for EDP you should be aware of, and 2 of them can't be ignored.
