Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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 note that Novartis AG (VTX:NOVN) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?
Why Does Debt Bring Risk?
Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. If things get really bad, the lenders can take control of the business. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. 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 Novartis's Net Debt?
You can click the graphic below for the historical numbers, but it shows that as of June 2025 Novartis had US$30.8b of debt, an increase on US$27.2b, over one year. However, it does have US$6.73b in cash offsetting this, leading to net debt of about US$24.1b.
A Look At Novartis' Liabilities
We can see from the most recent balance sheet that Novartis had liabilities of US$31.7b falling due within a year, and liabilities of US$30.6b due beyond that. On the other hand, it had cash of US$6.73b and US$9.18b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$46.4b.
Novartis has a very large market capitalization of US$224.5b, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. However, it is still worthwhile taking a close look at its ability to pay off debt.
Check out our latest analysis for Novartis
We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.
Novartis has a low net debt to EBITDA ratio of only 1.0. And its EBIT easily covers its interest expense, being 36.2 times the size. So we're pretty relaxed about its super-conservative use of debt. Another good sign is that Novartis has been able to increase its EBIT by 26% 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 Novartis 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.
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. Over the last three years, Novartis recorded free cash flow worth a fulsome 95% 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 Novartis's demonstrated ability to cover its interest expense with its EBIT delights us like a fluffy puppy does a toddler. And the good news does not stop there, as its conversion of EBIT to free cash flow also supports that impression! Overall, we don't think Novartis is taking any bad risks, as its debt load seems modest. So the balance sheet looks pretty healthy, to us. 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.
