David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the permanent loss of capital.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. As with many other companies Westinghouse Air Brake Technologies Corporation (NYSE:WAB) makes use of debt. But the more important question is: how much risk is that debt creating?

Why Does Debt Bring Risk?

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. 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. 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 examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does Westinghouse Air Brake Technologies Carry?

The chart below, which you can click on for greater detail, shows that Westinghouse Air Brake Technologies had US$4.00b in debt in March 2024; about the same as the year before. However, because it has a cash reserve of US$634.0m, its net debt is less, at about US$3.37b.

How Strong Is Westinghouse Air Brake Technologies' Balance Sheet?

The latest balance sheet data shows that Westinghouse Air Brake Technologies had liabilities of US$3.15b due within a year, and liabilities of US$5.09b falling due after that. Offsetting this, it had US$634.0m in cash and US$1.54b in receivables that were due within 12 months. So its liabilities total US$6.07b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because Westinghouse Air Brake Technologies is worth a massive US$27.7b, 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).

With a debt to EBITDA ratio of 1.7, Westinghouse Air Brake Technologies uses debt artfully but responsibly. And the fact that its trailing twelve months of EBIT was 7.1 times its interest expenses harmonizes with that theme. It is well worth noting that Westinghouse Air Brake Technologies's EBIT shot up like bamboo after rain, gaining 32% in the last twelve months. That'll make it easier to manage its debt. The balance sheet is clearly the area to focus on when you are analysing debt. 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.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the last three years, Westinghouse Air Brake Technologies recorded free cash flow worth a fulsome 81% 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

Happily, Westinghouse Air Brake Technologies's impressive conversion of EBIT to free cash flow implies it has the upper hand on its debt. And that's just the beginning of the good news since its EBIT growth rate is also very heartening. Looking at the bigger picture, we think Westinghouse Air Brake Technologies's use of debt seems quite reasonable and we're not concerned about it. After all, sensible leverage can boost returns on equity. There's no doubt that we learn most about debt from the balance sheet. But ultimately, every company can contain risks that exist outside of the balance sheet.
