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 seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. We can see that Xcel Energy Inc. (NASDAQ:XEL) does use debt in its business. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

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. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. 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.

How Much Debt Does Xcel Energy Carry?

You can click the graphic below for the historical numbers, but it shows that as of June 2024 Xcel Energy had US$29.4b of debt, an increase on US$25.6b, over one year. However, it also had US$1.62b in cash, and so its net debt is US$27.8b.

A Look At Xcel Energy's Liabilities

According to the last reported balance sheet, Xcel Energy had liabilities of US$5.90b due within 12 months, and liabilities of US$44.1b due beyond 12 months. On the other hand, it had cash of US$1.62b and US$2.20b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$46.2b.

Given this deficit is actually higher than the company's massive market capitalization of US$36.0b, we think shareholders really should watch Xcel Energy's debt levels, like a parent watching their child ride a bike for the first time. Hypothetically, extremely heavy dilution would be required if the company were forced to pay down its liabilities by raising capital at the current share price.

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).

Weak interest cover of 2.4 times and a disturbingly high net debt to EBITDA ratio of 5.1 hit our confidence in Xcel Energy like a one-two punch to the gut. The debt burden here is substantial. On a slightly more positive note, Xcel Energy grew its EBIT at 11% over the last year, further increasing its ability to manage debt. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Xcel Energy 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 we always check how much of that EBIT is translated into free cash flow. Over the last three years, Xcel 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, Xcel 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 Xcel Energy commonly do use debt without problems. Overall, it seems to us that Xcel Energy's balance sheet is really quite a risk to the business. So we're almost as wary of this stock as a hungry kitten is about falling into its owner's fish pond: once bitten, twice shy, as they say. 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. These risks can be hard to spot. Every company has them, and we've spotted 2 warning signs for Xcel Energy (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.
