Is Westinghouse Air Brake Technologies (NYSE:WAB) Using Too Much Debt?

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. As with many other companies Westinghouse Air Brake Technologies Corporation (NYSE:WAB) makes use of debt. But is this debt a concern to shareholders?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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. Of course, plenty of companies use debt to fund growth, without any negative consequences. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Westinghouse Air Brake Technologies's Net Debt?

The chart below, which you can click on for greater detail, shows that Westinghouse Air Brake Technologies had US$4.16b in debt in March 2023; about the same as the year before. However, it does have US$410.0m in cash offsetting this, leading to net debt of about US$3.75b.

A Look At Westinghouse Air Brake Technologies' Liabilities

Zooming in on the latest balance sheet data, we can see that Westinghouse Air Brake Technologies had liabilities of US$4.17b due within 12 months and liabilities of US$4.37b due beyond that. Offsetting this, it had US$410.0m in cash and US$1.58b in receivables that were due within 12 months. So it has liabilities totalling US$6.55b more than its cash and near-term receivables, combined.

This deficit isn't so bad because Westinghouse Air Brake Technologies is worth a massive US$16.7b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (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).

Westinghouse Air Brake Technologies has net debt worth 2.4 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 5.8 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. One way Westinghouse Air Brake Technologies could vanquish its debt would be if it stops borrowing more but continues to grow EBIT at around 11%, as it did over the last year. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Westinghouse Air Brake Technologies 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 we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the last three years, Westinghouse Air Brake Technologies recorded free cash flow worth a fulsome 86% 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 Westinghouse Air Brake Technologies's demonstrated ability to convert EBIT to free cash flow delights us like a fluffy puppy does a toddler. But truth be told we feel its net debt to EBITDA does undermine this impression a bit. Looking at all the aforementioned factors together, it strikes us that Westinghouse Air Brake Technologies can handle its debt fairly comfortably. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one.
