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. As with many other companies Ultra Clean Holdings, Inc. (NASDAQ:UCTT) makes use of debt. But should shareholders be worried about its use of debt?

When Is Debt Dangerous?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest 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 Ultra Clean Holdings's Debt?

As you can see below, Ultra Clean Holdings had US$475.2m of debt, at March 2024, which is about the same as the year before. You can click the chart for greater detail. However, it also had US$293.0m in cash, and so its net debt is US$182.2m.

How Strong Is Ultra Clean Holdings' Balance Sheet?

According to the last reported balance sheet, Ultra Clean Holdings had liabilities of US$329.4m due within 12 months, and liabilities of US$669.1m due beyond 12 months. Offsetting this, it had US$293.0m in cash and US$194.5m in receivables that were due within 12 months. So it has liabilities totalling US$511.0m more than its cash and near-term receivables, combined.

While this might seem like a lot, it is not so bad since Ultra Clean Holdings has a market capitalization of US$2.52b, and so it could probably strengthen its balance sheet by raising capital if it needed to. However, it is still worthwhile taking a close look at its ability to pay off debt.

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).

While Ultra Clean Holdings has a quite reasonable net debt to EBITDA multiple of 1.6, its interest cover seems weak, at 1.0. In large part that's it has so much depreciation and amortisation. These charges may be non-cash, so they could be excluded when it comes to paying down debt. But the accounting charges are there for a reason -- some assets are seen to be losing value. Either way there's no doubt the stock is using meaningful leverage. Shareholders should be aware that Ultra Clean Holdings's EBIT was down 73% last year. If that earnings trend continues then paying off its debt will be about as easy as herding cats on to a roller coaster. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Ultra Clean Holdings's ability to maintain a healthy balance sheet going forward. 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. Looking at the most recent three years, Ultra Clean Holdings recorded free cash flow of 23% of its EBIT, which is weaker than we'd expect. That weak cash conversion makes it more difficult to handle indebtedness.

Our View

On the face of it, Ultra Clean Holdings's interest cover left us tentative about the stock, and its EBIT growth rate was no more enticing than the one empty restaurant on the busiest night of the year. But at least its net debt to EBITDA is not so bad. Looking at the bigger picture, it seems clear to us that Ultra Clean Holdings's use of debt is creating risks for the company. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. These risks can be hard to spot. Every company has them, and we've spotted 1 warning sign for Ultra Clean Holdings you should know about.

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
