Westinghouse Air Brake Technologies (NYSE:WAB) Seems To Use Debt Quite Sensibly

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 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. 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 Dangerous?

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. 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 thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Westinghouse Air Brake Technologies's Debt?

The chart below, which you can click on for greater detail, shows that Westinghouse Air Brake Technologies had US$4.07b in debt in December 2023; about the same as the year before. However, it does have US$625.0m in cash offsetting this, leading to net debt of about US$3.44b.

A Look At Westinghouse Air Brake Technologies' Liabilities

The latest balance sheet data shows that Westinghouse Air Brake Technologies had liabilities of US$4.06b due within a year, and liabilities of US$4.41b falling due after that. On the other hand, it had cash of US$625.0m and US$1.68b worth of receivables due within a year. So its liabilities total US$6.16b more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Westinghouse Air Brake Technologies has a huge market capitalization of US$26.6b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its 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 1.9 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 6.4 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. We note that Westinghouse Air Brake Technologies grew its EBIT by 24% in the last year, and that should make it easier to pay down debt, going forward. 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 Westinghouse Air Brake Technologies's ability to maintain a healthy balance sheet going forward. 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 we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Westinghouse Air Brake Technologies generated free cash flow amounting to a very robust 87% of its EBIT, more than we'd expect. That puts it in a very strong position to pay down debt.

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. And the good news does not stop there, as its EBIT growth rate also supports that impression! Zooming out, Westinghouse Air Brake Technologies seems to use debt quite reasonably; and that gets the nod from us. While debt does bring risk, when used wisely it can also bring a higher return on equity. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it.
