The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. We can see that Envista Holdings Corporation (NYSE:NVST) does use debt in its business. But is this debt a concern to shareholders?

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. 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 examine debt levels, we first consider both cash and debt levels, together.

What Is Envista Holdings's Net Debt?

As you can see below, Envista Holdings had US$1.42b of debt at September 2024, down from US$1.50b a year prior. However, because it has a cash reserve of US$991.3m, its net debt is less, at about US$430.1m.

How Strong Is Envista Holdings' Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Envista Holdings had liabilities of US$865.5m due within 12 months and liabilities of US$1.57b due beyond that. Offsetting this, it had US$991.3m in cash and US$392.1m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.05b.

Envista Holdings has a market capitalization of US$3.37b, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While Envista Holdings's low debt to EBITDA ratio of 1.5 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 3.3 times last year does give us pause. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. Importantly, Envista Holdings's EBIT fell a jaw-dropping 57% in the last twelve months. If that earnings trend continues then paying off its debt will be about as easy as herding cats on to a roller coaster. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Envista Holdings'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 the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. During the last three years, Envista Holdings produced sturdy free cash flow equating to 69% of its EBIT, about what we'd expect. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Envista Holdings's EBIT growth rate was a real negative on this analysis, although the other factors we considered cast it in a significantly better light. In particular, its conversion of EBIT to free cash flow was re-invigorating. We should also note that Medical Equipment industry companies like Envista Holdings commonly do use debt without problems. Looking at all the angles mentioned above, it does seem to us that Envista Holdings is a somewhat risky investment as a result of its debt. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. Given our hesitation about the stock, it would be good to know if Envista Holdings insiders have sold any shares recently. You click here to find out if insiders have sold recently.
