Legendary fund manager Li Lu (who Charlie Munger backed) once said, 'The biggest investment risk is not the volatility of prices, but whether you will suffer a 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 Adani Green Energy Limited (NSE:ADANIGREEN) makes use of debt. But is this debt a concern to shareholders?
Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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 think about a company's use of debt, we first look at cash and debt together.
The image below, which you can click on for greater detail, shows that at September 2025 Adani Green Energy had debt of ₹860.0b, up from ₹656.1b in one year. However, it does have ₹60.7b in cash offsetting this, leading to net debt of about ₹799.3b.
The latest balance sheet data shows that Adani Green Energy had liabilities of ₹172.0b due within a year, and liabilities of ₹789.2b falling due after that. Offsetting these obligations, it had cash of ₹60.7b as well as receivables valued at ₹21.3b due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by ₹879.2b.
This deficit isn't so bad because Adani Green Energy is worth a massive ₹1.68t, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.
Check out our latest analysis for Adani Green Energy
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.
Weak interest cover of 1.4 times and a disturbingly high net debt to EBITDA ratio of 8.0 hit our confidence in Adani Green Energy like a one-two punch to the gut. The debt burden here is substantial. On a slightly more positive note, Adani Green Energy grew its EBIT at 18% over the last year, further increasing its ability to manage 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 Adani Green Energy's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.
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, Adani Green Energy burned a lot of cash. While that may be a result of expenditure for growth, it does make the debt far more risky.
On the face of it, Adani Green Energy's net debt to EBITDA left us tentative about the stock, and its conversion of EBIT to free cash flow was no more enticing than the one empty restaurant on the busiest night of the year. But at least it's pretty decent at growing its EBIT; that's encouraging. Overall, we think it's fair to say that Adani Green Energy has enough debt that there are some real risks around the balance sheet. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. For instance, we've identified 2 warning signs for Adani Green Energy that you should be aware of.
