Does Martin Marietta Materials (NYSE:MLM) Have A Healthy Balance Sheet?

Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 Martin Marietta Materials, Inc. (NYSE:MLM) does use debt in its business. But the more important question is: how much risk is that debt creating?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. 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 Martin Marietta Materials's Debt?

As you can see below, Martin Marietta Materials had US$5.04b of debt, at June 2023, which is about the same as the year before. You can click the chart for greater detail. However, because it has a cash reserve of US$421.5m, its net debt is less, at about US$4.62b.

A Look At Martin Marietta Materials' Liabilities

We can see from the most recent balance sheet that Martin Marietta Materials had liabilities of US$1.44b falling due within a year, and liabilities of US$6.38b due beyond that. Offsetting this, it had US$421.5m in cash and US$991.1m in receivables that were due within 12 months. So its liabilities total US$6.41b more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Martin Marietta Materials has a huge market capitalization of US$27.6b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

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).

Martin Marietta Materials's net debt of 2.5 times EBITDA suggests graceful use of debt. And the fact that its trailing twelve months of EBIT was 8.6 times its interest expenses harmonizes with that theme. Importantly, Martin Marietta Materials grew its EBIT by 32% over the last twelve months, and that growth will make it easier to handle its debt. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Martin Marietta Materials 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.

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 most recent three years, Martin Marietta Materials recorded free cash flow worth 58% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Martin Marietta Materials's EBIT growth rate suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. But, on a more sombre note, we are a little concerned by its net debt to EBITDA. When we consider the range of factors above, it looks like Martin Marietta Materials is pretty sensible with its use of debt. While that brings some risk, it can also enhance returns for shareholders. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. These risks can be hard to spot. Every company has them, and we've spotted 1 warning sign for Martin Marietta Materials you should know about.

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
