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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We can see that MDU Resources Group, Inc. (NYSE:MDU) does use debt in its business. But should shareholders be worried about its use of debt?

What Risk Does Debt Bring?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. 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. 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. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is MDU Resources Group's Debt?

As you can see below, MDU Resources Group had US$2.39b of debt at March 2024, down from US$3.35b a year prior. However, it also had US$89.3m in cash, and so its net debt is US$2.30b.

A Look At MDU Resources Group's Liabilities

The latest balance sheet data shows that MDU Resources Group had liabilities of US$922.8m due within a year, and liabilities of US$3.94b falling due after that. Offsetting this, it had US$89.3m in cash and US$932.1m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$3.84b.

This deficit is considerable relative to its market capitalization of US$5.14b, so it does suggest shareholders should keep an eye on MDU Resources Group's use of debt. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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.

MDU Resources Group's debt is 3.4 times its EBITDA, and its EBIT cover its interest expense 3.8 times over. Taken together this implies that, while we wouldn't want to see debt levels rise, we think it can handle its current leverage. On a slightly more positive note, MDU Resources Group grew its EBIT at 15% 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 MDU Resources Group 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.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, MDU Resources Group recorded negative free cash flow, in total. Debt is usually more expensive, and almost always more risky in the hands of a company with negative free cash flow. Shareholders ought to hope for an improvement.

Our View

We'd go so far as to say MDU Resources Group's conversion of EBIT to free cash flow was disappointing. But on the bright side, its EBIT growth rate is a good sign, and makes us more optimistic. Looking at the bigger picture, it seems clear to us that MDU Resources Group's use of debt is creating risks for the company. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. 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.
