Is Tetra Tech (NASDAQ:TTEK) Using Too Much Debt?

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.' 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. As with many other companies Tetra Tech, Inc. (NASDAQ:TTEK) makes use of debt. But should shareholders be worried about its use of debt?

Why Does Debt Bring Risk?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. If things get really bad, the lenders can take control of the business. 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. When we think about a company's use of debt, we first look at cash and debt together.

What Is Tetra Tech's Debt?

The image below, which you can click on for greater detail, shows that Tetra Tech had debt of US$951.0m at the end of March 2024, a reduction from US$1.08b over a year. However, it also had US$210.3m in cash, and so its net debt is US$740.7m.

A Look At Tetra Tech's Liabilities

We can see from the most recent balance sheet that Tetra Tech had liabilities of US$1.19b falling due within a year, and liabilities of US$1.29b due beyond that. On the other hand, it had cash of US$210.3m and US$1.14b worth of receivables due within a year. So it has liabilities totalling US$1.13b more than its cash and near-term receivables, combined.

Of course, Tetra Tech has a titanic market capitalization of US$11.7b, so these liabilities are probably manageable. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

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).

Tetra Tech has net debt of just 1.4 times EBITDA, indicating that it is certainly not a reckless borrower. And this view is supported by the solid interest coverage, with EBIT coming in at 9.8 times the interest expense over the last year. Another good sign is that Tetra Tech has been able to increase its EBIT by 27% in twelve months, making it easier to pay down debt. 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 Tetra Tech 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 it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Tetra Tech recorded free cash flow worth a fulsome 80% of its EBIT, which is stronger than we'd usually expect. That puts it in a very strong position to pay down debt.

Our View

The good news is that Tetra Tech's demonstrated ability to convert EBIT to free cash flow delights us like a fluffy puppy does a toddler. And the good news does not stop there, as its EBIT growth rate also supports that impression! Overall, we don't think Tetra Tech is taking any bad risks, as its debt load seems modest. So we're not worried about the use of a little leverage on the balance sheet. 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. For example, we've discovered 3 warning signs for Tetra Tech that you should be aware of before investing here.
