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 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. We note that Saia, Inc. (NASDAQ:SAIA) does have debt on its balance sheet. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. 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.

What Is Saia's Net Debt?

As you can see below, at the end of June 2024, Saia had US$167.0m of debt, up from none a year ago. Click the image for more detail. However, it also had US$11.2m in cash, and so its net debt is US$155.8m.

How Healthy Is Saia's Balance Sheet?

According to the last reported balance sheet, Saia had liabilities of US$327.8m due within 12 months, and liabilities of US$493.2m due beyond 12 months. Offsetting this, it had US$11.2m in cash and US$383.0m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$426.8m.

Since publicly traded Saia shares are worth a very impressive total of US$11.0b, it seems unlikely that this level of liabilities would be a major threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse. Carrying virtually no net debt, Saia has a very light debt load indeed.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Saia has net debt of just 0.23 times EBITDA, suggesting it could ramp leverage without breaking a sweat. And remarkably, despite having net debt, it actually received more in interest over the last twelve months than it had to pay. So there's no doubt this company can take on debt while staying cool as a cucumber. And we also note warmly that Saia grew its EBIT by 13% last year, making its debt load easier to handle. 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 Saia's ability to maintain a healthy balance sheet going forward.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Saia recorded negative free cash flow, in total. Debt is usually more expensive, and almost always more risky in the hands of a company with negative free cash flow. Shareholders ought to hope for an improvement.

Our View

Happily, Saia's impressive interest cover implies it has the upper hand on its debt. But we must concede we find its conversion of EBIT to free cash flow has the opposite effect. Looking at all the aforementioned factors together, it strikes us that Saia can handle its debt fairly comfortably. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one. 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.
