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.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. Importantly, Primoris Services Corporation (NYSE:PRIM) does carry debt. But the real question is whether this debt is making the company risky.

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Primoris Services's Net Debt?

The image below, which you can click on for greater detail, shows that Primoris Services had debt of US$933.0m at the end of June 2024, a reduction from US$1.11b over a year. However, it also had US$209.2m in cash, and so its net debt is US$723.8m.

How Healthy Is Primoris Services' Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Primoris Services had liabilities of US$1.48b due within 12 months and liabilities of US$1.27b due beyond that. On the other hand, it had cash of US$209.2m and US$1.72b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$825.9m.

While this might seem like a lot, it is not so bad since Primoris Services has a market capitalization of US$2.73b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But it's clear that we should definitely closely examine whether it can manage its debt without 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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Primoris Services's net debt is sitting at a very reasonable 1.8 times its EBITDA, while its EBIT covered its interest expense just 3.8 times last year. While these numbers do not alarm us, it's worth noting that the cost of the company's debt is having a real impact. We note that Primoris Services grew its EBIT by 26% in the last year, and that should make it easier to pay down debt, going forward. 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 Primoris Services can strengthen its balance sheet over time.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Primoris Services reported free cash flow worth 5.9% of its EBIT, which is really quite low. That limp level of cash conversion undermines its ability to manage and pay down debt.

Our View

When it comes to the balance sheet, the standout positive for Primoris Services was the fact that it seems able to grow its EBIT confidently. However, our other observations weren't so heartening. In particular, conversion of EBIT to free cash flow gives us cold feet. When we consider all the factors mentioned above, we do feel a bit cautious about Primoris Services's use of debt. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. 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. We've identified 2 warning signs with Primoris Services , and understanding them should be part of your investment process.
