Duke Energy (NYSE:DUK) Has A Somewhat Strained Balance Sheet

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 Duke Energy Corporation (NYSE:DUK) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

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. 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. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Duke Energy's Net Debt?

You can click the graphic below for the historical numbers, but it shows that as of September 2024 Duke Energy had US$84.1b of debt, an increase on US$78.5b, over one year. And it doesn't have much cash, so its net debt is about the same.

How Strong Is Duke Energy's Balance Sheet?

We can see from the most recent balance sheet that Duke Energy had liabilities of US$17.4b falling due within a year, and liabilities of US$115.9b due beyond that. On the other hand, it had cash of US$376.0m and US$4.68b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$128.3b.

This deficit casts a shadow over the US$84.1b company, like a colossus towering over mere mortals. So we definitely think shareholders need to watch this one closely. At the end of the day, Duke Energy 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.

Duke Energy shareholders face the double whammy of a high net debt to EBITDA ratio (5.9), and fairly weak interest coverage, since EBIT is just 2.4 times the interest expense. This means we'd consider it to have a heavy debt load. On a slightly more positive note, Duke Energy grew its EBIT at 14% 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 ultimately the future profitability of the business will decide if Duke Energy can strengthen its balance sheet over time. 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. Over the last three years, Duke Energy 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.

Our View

To be frank both Duke Energy's net debt to EBITDA and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. But at least it's pretty decent at growing its EBIT; that's encouraging. We should also note that Electric Utilities industry companies like Duke Energy commonly do use debt without problems. After considering the datapoints discussed, we think Duke Energy has too much debt. That sort of riskiness is ok for some, but it certainly doesn't float our boat. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet. To that end, you should learn about the 2 warning signs we've spotted with Duke Energy (including 1 which is potentially serious) .
