Is MKS Instruments (NASDAQ:MKSI) A Risky Investment?

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. As with many other companies MKS Instruments, Inc. (NASDAQ:MKSI) makes use of debt. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

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. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is MKS Instruments's Debt?

The chart below, which you can click on for greater detail, shows that MKS Instruments had US$4.87b in debt in September 2023; about the same as the year before. However, because it has a cash reserve of US$860.0m, its net debt is less, at about US$4.01b.

How Healthy Is MKS Instruments' Balance Sheet?

We can see from the most recent balance sheet that MKS Instruments had liabilities of US$838.0m falling due within a year, and liabilities of US$5.83b due beyond that. On the other hand, it had cash of US$860.0m and US$618.0m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$5.19b.

This is a mountain of leverage relative to its market capitalization of US$5.76b. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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.

While we wouldn't worry about MKS Instruments's net debt to EBITDA ratio of 4.8, we think its super-low interest cover of 1.3 times is a sign of high leverage. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Even worse, MKS Instruments saw its EBIT tank 35% over the last 12 months. If earnings continue to follow that trajectory, paying off that debt load will be harder than convincing us to run a marathon in the rain. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine MKS Instruments's ability to maintain a healthy balance sheet going forward.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the most recent three years, MKS Instruments recorded free cash flow worth 62% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

To be frank both MKS Instruments's interest cover and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. But at least it's pretty decent at converting EBIT to free cash flow; that's encouraging. We're quite clear that we consider MKS Instruments to be really rather risky, as a result of its balance sheet health. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity. 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. Case in point: We've spotted 1 warning sign for MKS Instruments you should be aware of.
