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

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. Importantly, Duke Energy Corporation (NYSE:DUK) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt Dangerous?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. 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.

What Is Duke Energy's Net Debt?

As you can see below, at the end of March 2025, Duke Energy had US$86.4b of debt, up from US$81.4b a year ago. Click the image for more detail. And it doesn't have much cash, so its net debt is about the same.

How Healthy Is Duke Energy's Balance Sheet?

We can see from the most recent balance sheet that Duke Energy had liabilities of US$16.6b falling due within a year, and liabilities of US$119.1b due beyond that. Offsetting these obligations, it had cash of US$475.0m as well as receivables valued at US$4.56b due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$130.6b.

When you consider that this deficiency exceeds the company's huge US$91.2b market capitalization, you might well be inclined to review the balance sheet intently. In the scenario where the company had to clean up its balance sheet quickly, it seems likely shareholders would suffer extensive dilution.

View our latest analysis for Duke 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). 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).

Weak interest cover of 2.5 times and a disturbingly high net debt to EBITDA ratio of 5.8 hit our confidence in Duke Energy like a one-two punch to the gut. The debt burden here is substantial. Fortunately, Duke Energy grew its EBIT by 9.5% in the last year, slowly shrinking its debt relative to earnings. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Duke 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.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Duke Energy saw substantial negative free cash flow, in total. While that may be a result of expenditure for growth, it does make the debt far more risky.

Our View

On the face of it, Duke 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 on the bright side, its EBIT growth rate is a good sign, and makes us more optimistic. We should also note that Electric Utilities industry companies like Duke Energy commonly do use debt without problems. Overall, it seems to us that Duke Energy's balance sheet is really quite a risk to the business. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity. 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 3 warning signs we've spotted with Duke Energy (including 1 which can't be ignored) .

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.
