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. We note that Zoetis Inc. (NYSE:ZTS) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.

What Risk Does Debt Bring?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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 think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Zoetis Carry?

The chart below, which you can click on for greater detail, shows that Zoetis had US$6.62b in debt in March 2024; about the same as the year before. However, it also had US$1.98b in cash, and so its net debt is US$4.64b.

How Healthy Is Zoetis' Balance Sheet?

The latest balance sheet data shows that Zoetis had liabilities of US$1.91b due within a year, and liabilities of US$7.39b falling due after that. Offsetting this, it had US$1.98b in cash and US$1.29b in receivables that were due within 12 months. So it has liabilities totalling US$6.03b more than its cash and near-term receivables, combined.

Of course, Zoetis has a titanic market capitalization of US$78.1b, so these liabilities are probably manageable. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

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).

Zoetis has a low net debt to EBITDA ratio of only 1.3. And its EBIT easily covers its interest expense, being 24.2 times the size. So you could argue it is no more threatened by its debt than an elephant is by a mouse. The good news is that Zoetis has increased its EBIT by 9.4% over twelve months, which should ease any concerns about debt repayment. 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 Zoetis's ability to maintain a healthy balance sheet going forward.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Zoetis recorded free cash flow worth 54% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Zoetis's interest cover suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. And we also thought its net debt to EBITDA was a positive. Taking all this data into account, it seems to us that Zoetis takes a pretty sensible approach to debt. That means they are taking on a bit more risk, in the hope of boosting shareholder returns. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it.
