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.' 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 Amentum Holdings, Inc. (NYSE:AMTM) makes use of debt. But the more important question is: how much risk is that debt creating?

What Risk Does Debt Bring?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Amentum Holdings's Debt?

The image below, which you can click on for greater detail, shows that at September 2024 Amentum Holdings had debt of US$4.68b, up from none in one year. However, because it has a cash reserve of US$452.0m, its net debt is less, at about US$4.23b.

How Healthy Is Amentum Holdings' Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Amentum Holdings had liabilities of US$1.97b due within 12 months and liabilities of US$5.46b due beyond that. Offsetting these obligations, it had cash of US$452.0m as well as receivables valued at US$2.40b due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$4.57b.

This is a mountain of leverage relative to its market capitalization of US$4.82b. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe dilution.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Amentum Holdings shareholders face the double whammy of a high net debt to EBITDA ratio (9.0), and fairly weak interest coverage, since EBIT is just 0.50 times the interest expense. This means we'd consider it to have a heavy debt load. Even worse, Amentum Holdings saw its EBIT tank 34% over the last 12 months. If earnings keep going like that over the long term, it has a snowball's chance in hell of paying off that 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 Amentum Holdings can strengthen its balance sheet over time.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Amentum Holdings recorded free cash flow worth 54% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

To be frank both Amentum Holdings's interest cover and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. But on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. We're quite clear that we consider Amentum Holdings to be really rather risky, as a result of its balance sheet health. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet.
