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 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 Vestis Corporation (NYSE:VSTS) does have debt on its balance sheet. But is this debt a concern to shareholders?

When Is Debt Dangerous?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. 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 Vestis's Debt?

The chart below, which you can click on for greater detail, shows that Vestis had US$1.16b in debt in October 2025; about the same as the year before. On the flip side, it has US$29.7m in cash leading to net debt of about US$1.13b.

How Healthy Is Vestis' Balance Sheet?

We can see from the most recent balance sheet that Vestis had liabilities of US$409.0m falling due within a year, and liabilities of US$1.63b due beyond that. Offsetting this, it had US$29.7m in cash and US$162.3m in receivables that were due within 12 months. So it has liabilities totalling US$1.85b more than its cash and near-term receivables, combined.

The deficiency here weighs heavily on the US$840.5m company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we'd watch its balance sheet closely, without a doubt. After all, Vestis would likely require a major re-capitalisation if it had to pay its creditors today.

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.

While we wouldn't worry about Vestis's net debt to EBITDA ratio of 5.0, we think its super-low interest cover of 0.90 times is a sign of high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. Even worse, Vestis saw its EBIT tank 49% 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 Vestis can strengthen its balance sheet over time.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Happily for any shareholders, Vestis actually produced more free cash flow than EBIT over the last three years. There's nothing better than incoming cash when it comes to staying in your lenders' good graces.

Our View

On the face of it, Vestis's EBIT growth rate left us tentative about the stock, and its level of total liabilities was no more enticing than the one empty restaurant on the busiest night of the year. 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 Vestis to be really rather risky, as a result of its balance sheet health. So we're almost as wary of this stock as a hungry kitten is about falling into its owner's fish pond: once bitten, twice shy, as they say. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it.
