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. As with many other companies The AES Corporation (NYSE:AES) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

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. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. 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.

What Is AES's Net Debt?

The image below, which you can click on for greater detail, shows that at March 2024 AES had debt of US$30.5b, up from US$24.8b in one year. On the flip side, it has US$2.39b in cash leading to net debt of about US$28.1b.

How Healthy Is AES' Balance Sheet?

We can see from the most recent balance sheet that AES had liabilities of US$9.21b falling due within a year, and liabilities of US$30.1b due beyond that. Offsetting this, it had US$2.39b in cash and US$1.62b in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$35.3b.

The deficiency here weighs heavily on the US$12.7b company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we definitely think shareholders need to watch this one closely. At the end of the day, AES 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). 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).

AES has a rather high debt to EBITDA ratio of 8.2 which suggests a meaningful debt load. However, its interest coverage of 2.8 is reasonably strong, which is a good sign. More concerning, AES saw its EBIT drop by 6.9% in the last twelve months. If it keeps going like that paying off its debt will be like running on a treadmill -- a lot of effort for not much advancement. 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 AES can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, AES burned a lot of cash. While that may be a result of expenditure for growth, it does make the debt far more risky.

Our View

To be frank both AES's conversion of EBIT to free cash flow and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. And furthermore, its interest cover also fails to instill confidence. We think the chances that AES has too much debt a very significant. To our minds, that means the stock is rather high risk, and probably one to avoid; but to each their own (investing) style. 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 4 warning signs for AES (of which 1 doesn't sit too well with us!) you should know about.

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
