Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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. We note that AECOM (NYSE:ACM) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.

What Risk Does Debt Bring?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. 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, 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.

How Much Debt Does AECOM Carry?

The image below, which you can click on for greater detail, shows that at September 2024 AECOM had debt of US$2.46b, up from US$2.14b in one year. On the flip side, it has US$1.59b in cash leading to net debt of about US$869.6m.

How Healthy Is AECOM's Balance Sheet?

We can see from the most recent balance sheet that AECOM had liabilities of US$6.37b falling due within a year, and liabilities of US$3.32b due beyond that. Offsetting these obligations, it had cash of US$1.59b as well as receivables valued at US$4.76b due within 12 months. So its liabilities total US$3.34b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because AECOM is worth a massive US$14.7b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. 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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

With net debt sitting at just 0.79 times EBITDA, AECOM is arguably pretty conservatively geared. And this view is supported by the solid interest coverage, with EBIT coming in at 7.4 times the interest expense over the last year. Also good is that AECOM grew its EBIT at 17% over the last year, further increasing its ability to manage debt. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if AECOM can strengthen its balance sheet over time.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the most recent three years, AECOM recorded free cash flow worth 77% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

The good news is that AECOM'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 net debt to EBITDA is also very heartening. Looking at the bigger picture, we think AECOM's use of debt seems quite reasonable and we're not concerned about it. After all, sensible leverage can boost returns on equity. We'd be motivated to research the stock further if we found out that AECOM insiders have bought shares recently.
