Legendary fund manager Li Lu (who Charlie Munger backed) once said, '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. As with many other companies Noble Corporation plc (NYSE:NE) makes use of debt. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. If things get really bad, the lenders can take control of the business. 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, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Noble's Net Debt?

As you can see below, at the end of March 2024, Noble had US$586.6m of debt, up from US$520.7m a year ago. Click the image for more detail. However, it does have US$212.5m in cash offsetting this, leading to net debt of about US$374.2m.

A Look At Noble's Liabilities

Zooming in on the latest balance sheet data, we can see that Noble had liabilities of US$603.4m due within 12 months and liabilities of US$919.8m due beyond that. On the other hand, it had cash of US$212.5m and US$668.1m worth of receivables due within a year. So its liabilities total US$642.6m more than the combination of its cash and short-term receivables.

Since publicly traded Noble shares are worth a total of US$6.54b, it seems unlikely that this level of liabilities would be a major threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

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).

Noble has net debt of just 0.44 times EBITDA, indicating that it is certainly not a reckless borrower. And this view is supported by the solid interest coverage, with EBIT coming in at 9.9 times the interest expense over the last year. On top of that, Noble grew its EBIT by 71% over the last twelve months, and that growth will make it easier to handle its debt. 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 Noble can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. In the last two years, Noble's free cash flow amounted to 34% of its EBIT, less than we'd expect. That weak cash conversion makes it more difficult to handle indebtedness.

Our View

The good news is that Noble's demonstrated ability to grow its EBIT delights us like a fluffy puppy does a toddler. But truth be told we feel its conversion of EBIT to free cash flow does undermine this impression a bit. Zooming out, Noble seems to use debt quite reasonably; and that gets the nod from us. After all, sensible leverage can boost returns on equity. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet. These risks can be hard to spot. Every company has them, and we've spotted 2 warning signs for Noble you should know about.
