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.' 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. As with many other companies Allison Transmission Holdings, Inc. (NYSE:ALSN) makes use of debt. But the real question is whether this debt is making the company risky.
Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. 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. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.
The chart below, which you can click on for greater detail, shows that Allison Transmission Holdings had US$2.40b in debt in September 2025; about the same as the year before. However, because it has a cash reserve of US$902.0m, its net debt is less, at about US$1.50b.
We can see from the most recent balance sheet that Allison Transmission Holdings had liabilities of US$438.0m falling due within a year, and liabilities of US$3.24b due beyond that. On the other hand, it had cash of US$902.0m and US$329.0m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$2.45b.
This deficit isn't so bad because Allison Transmission Holdings is worth US$8.23b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.
Check out our latest analysis for Allison Transmission Holdings
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).
Allison Transmission Holdings's net debt is only 1.3 times its EBITDA. And its EBIT covers its interest expense a whopping 11.2 times over. So you could argue it is no more threatened by its debt than an elephant is by a mouse. Allison Transmission Holdings's EBIT was pretty flat over the last year, but that shouldn't be an issue given the it doesn't have a lot of 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 Allison Transmission Holdings's ability to maintain a healthy balance sheet going forward. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.
Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Over the most recent three years, Allison Transmission Holdings recorded free cash flow worth 67% 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.
The good news is that Allison Transmission Holdings's demonstrated ability to cover its interest expense with its EBIT delights us like a fluffy puppy does a toddler. And that's just the beginning of the good news since its conversion of EBIT to free cash flow is also very heartening. Looking at all the aforementioned factors together, it strikes us that Allison Transmission Holdings can handle its debt fairly comfortably. On the plus side, this leverage can boost shareholder returns, but the potential downside is more risk of loss, so it's worth monitoring the balance sheet. 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.
