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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We note that Quanta Services, Inc. (NYSE:PWR) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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, debt can be an important tool in businesses, particularly capital heavy businesses. When we think about a company's use of debt, we first look at cash and debt together.

What Is Quanta Services's Debt?

You can click the graphic below for the historical numbers, but it shows that Quanta Services had US$3.34b of debt in June 2024, down from US$4.23b, one year before. However, it also had US$518.1m in cash, and so its net debt is US$2.83b.

How Strong Is Quanta Services' Balance Sheet?

The latest balance sheet data shows that Quanta Services had liabilities of US$5.32b due within a year, and liabilities of US$4.03b falling due after that. On the other hand, it had cash of US$518.1m and US$5.66b worth of receivables due within a year. So its liabilities total US$3.17b more than the combination of its cash and short-term receivables.

Since publicly traded Quanta Services shares are worth a very impressive total of US$45.7b, it seems unlikely that this level of liabilities would be a major threat. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

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.

With a debt to EBITDA ratio of 1.6, Quanta Services uses debt artfully but responsibly. And the fact that its trailing twelve months of EBIT was 7.0 times its interest expenses harmonizes with that theme. Also positive, Quanta Services grew its EBIT by 25% in the last year, and that should make it easier to pay down debt, going forward. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Quanta Services can strengthen its balance sheet over time. 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 clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the last three years, Quanta Services recorded free cash flow worth a fulsome 83% of its EBIT, which is stronger than we'd usually expect. That positions it well to pay down debt if desirable to do so.

Our View

Quanta Services's conversion of EBIT to free cash flow suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. And the good news does not stop there, as its EBIT growth rate also supports that impression! Zooming out, Quanta Services seems to use debt quite reasonably; and that gets the nod from us. While debt does bring risk, when used wisely it can also bring a higher return on equity. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. To that end, you should be aware of the 2 warning signs we've spotted with Quanta Services .

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
