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 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 Zurn Elkay Water Solutions Corporation (NYSE:ZWS) makes use of debt. But should shareholders be worried about its use of debt?

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. If things get really bad, the lenders can take control of the business. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. When we think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Zurn Elkay Water Solutions Carry?

The image below, which you can click on for greater detail, shows that Zurn Elkay Water Solutions had debt of US$474.3m at the end of June 2024, a reduction from US$533.4m over a year. On the flip side, it has US$162.7m in cash leading to net debt of about US$311.6m.

How Strong Is Zurn Elkay Water Solutions' Balance Sheet?

The latest balance sheet data shows that Zurn Elkay Water Solutions had liabilities of US$255.1m due within a year, and liabilities of US$832.0m falling due after that. Offsetting these obligations, it had cash of US$162.7m as well as receivables valued at US$240.8m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$683.6m.

Since publicly traded Zurn Elkay Water Solutions shares are worth a total of US$6.22b, it seems unlikely that this level of liabilities would be a major threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While Zurn Elkay Water Solutions's low debt to EBITDA ratio of 0.96 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 6.7 times last year does give us pause. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. On top of that, Zurn Elkay Water Solutions grew its EBIT by 45% over the last twelve months, and that growth will make it easier to handle its 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 Zurn Elkay Water Solutions 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.

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, Zurn Elkay Water Solutions recorded free cash flow worth a fulsome 94% of its EBIT, which is stronger than we'd usually expect. That positions it well to pay down debt if desirable to do so.

Our View

The good news is that Zurn Elkay Water Solutions's demonstrated ability to convert EBIT to free cash flow delights us like a fluffy puppy does a toddler. And that's just the beginning of the good news since its EBIT growth rate is also very heartening. Considering this range of factors, it seems to us that Zurn Elkay Water Solutions is quite prudent with its debt, and the risks seem well managed. So we're not worried about the use of a little leverage on the balance sheet.
