Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 NOV Inc. (NYSE:NOV) does have debt on its balance sheet. But should shareholders be worried about its use of debt?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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, 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 NOV Carry?

As you can see below, at the end of March 2024, NOV had US$1.81b of debt, up from US$1.73b a year ago. Click the image for more detail. However, it does have US$468.0m in cash offsetting this, leading to net debt of about US$1.34b.

How Strong Is NOV's Balance Sheet?

We can see from the most recent balance sheet that NOV had liabilities of US$2.27b falling due within a year, and liabilities of US$2.71b due beyond that. Offsetting this, it had US$468.0m in cash and US$2.68b in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.84b.

While this might seem like a lot, it is not so bad since NOV has a market capitalization of US$7.22b, and so it could probably strengthen its balance sheet by raising capital if it needed to. However, it is still worthwhile taking a close look at its ability to pay off debt.

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.

NOV has a low net debt to EBITDA ratio of only 1.3. And its EBIT easily covers its interest expense, being 11.7 times the size. So we're pretty relaxed about its super-conservative use of debt. In addition to that, we're happy to report that NOV has boosted its EBIT by 52%, thus reducing the spectre of future debt repayments. 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 NOV 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. During the last two years, NOV burned a lot of cash. While that may be a result of expenditure for growth, it does make the debt far more risky.

Our View

Based on what we've seen NOV is not finding it easy, given its conversion of EBIT to free cash flow, but the other factors we considered give us cause to be optimistic. There's no doubt that its ability to to grow its EBIT is pretty flash. Considering this range of data points, we think NOV is in a good position to manage its debt levels. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. 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 2 warning signs for NOV you should be aware of, and 1 of them doesn't sit too well with us.

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
