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. As with many other companies Mueller Water Products, Inc. (NYSE:MWA) makes use of debt. But is this debt a concern to shareholders?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

What Is Mueller Water Products's Net Debt?

The chart below, which you can click on for greater detail, shows that Mueller Water Products had US$445.2m in debt in June 2022; about the same as the year before. On the flip side, it has US$154.9m in cash leading to net debt of about US$290.3m.

A Look At Mueller Water Products' Liabilities

The latest balance sheet data shows that Mueller Water Products had liabilities of US$202.3m due within a year, and liabilities of US$603.5m falling due after that. Offsetting this, it had US$154.9m in cash and US$233.4m in receivables that were due within 12 months. So its liabilities total US$417.5m more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Mueller Water Products has a market capitalization of US$1.65b, and so it could probably strengthen its balance sheet by raising capital if it needed to. However, it is still worthwhile taking a close look at its ability to pay off debt.

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).

With net debt sitting at just 1.5 times EBITDA, Mueller Water Products is arguably pretty conservatively geared. And this view is supported by the solid interest coverage, with EBIT coming in at 8.2 times the interest expense over the last year. But the other side of the story is that Mueller Water Products saw its EBIT decline by 8.1% over the last year. That sort of decline, if sustained, will obviously make debt harder to handle. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine Mueller Water Products's ability to maintain a healthy balance sheet going forward.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Looking at the most recent three years, Mueller Water Products recorded free cash flow of 45% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

Mueller Water Products's interest cover was a real positive on this analysis, as was its net debt to EBITDA. On the other hand, its EBIT growth rate makes us a little less comfortable about its debt. Looking at all this data makes us feel a little cautious about Mueller Water Products's debt levels. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it. For example Mueller Water Products has 2 warning signs (and 1 which doesn't sit too well with us) we think 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.
