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.' 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 can see that Amgen Inc. (NASDAQ:AMGN) does use debt in its business. But the real question is whether this debt is making the company risky.

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Amgen Carry?

You can click the graphic below for the historical numbers, but it shows that as of March 2023 Amgen had US$61.6b of debt, an increase on US$36.9b, over one year. However, it does have US$31.6b in cash offsetting this, leading to net debt of about US$30.0b.

How Healthy Is Amgen's Balance Sheet?

We can see from the most recent balance sheet that Amgen had liabilities of US$14.2b falling due within a year, and liabilities of US$69.2b due beyond that. Offsetting this, it had US$31.6b in cash and US$5.74b in receivables that were due within 12 months. So its liabilities total US$46.1b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because Amgen is worth a massive US$119.4b, and thus could probably raise enough capital to shore up 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.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Amgen has net debt worth 2.3 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 5.8 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. Notably Amgen's EBIT was pretty flat over the last year. Ideally it can diminish its debt load by kick-starting earnings growth. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Amgen can strengthen its balance sheet over time. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the last three years, Amgen recorded free cash flow worth a fulsome 91% of its EBIT, which is stronger than we'd usually expect. That positions it well to pay down debt if desirable to do so.

Our View

On our analysis Amgen's conversion of EBIT to free cash flow should signal that it won't have too much trouble with its debt. But the other factors we noted above weren't so encouraging. For example, its net debt to EBITDA makes us a little nervous about its debt. Considering this range of data points, we think Amgen is in a good position to manage its debt levels. But a word of caution: we think debt levels are high enough to justify ongoing monitoring. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. Case in point: We've spotted 1 warning sign for Amgen you should be aware of.
