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. Importantly, Nabors Industries Ltd. (NYSE:NBR) does carry debt. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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, 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 Nabors Industries's Debt?

As you can see below, Nabors Industries had US$2.50b of debt, at September 2024, which is about the same as the year before. You can click the chart for greater detail. However, it also had US$459.3m in cash, and so its net debt is US$2.04b.

A Look At Nabors Industries' Liabilities

According to the last reported balance sheet, Nabors Industries had liabilities of US$571.6m due within 12 months, and liabilities of US$2.75b due beyond 12 months. Offsetting this, it had US$459.3m in cash and US$403.1m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$2.46b.

The deficiency here weighs heavily on the US$715.5m company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we'd watch its balance sheet closely, without a doubt. At the end of the day, Nabors Industries would probably need a major re-capitalization if its creditors were to demand repayment.

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).

Even though Nabors Industries's debt is only 2.3, its interest cover is really very low at 1.5. In large part that's it has so much depreciation and amortisation. These charges may be non-cash, so they could be excluded when it comes to paying down debt. But the accounting charges are there for a reason -- some assets are seen to be losing value. In any case, it's safe to say the company has meaningful debt. Unfortunately, Nabors Industries saw its EBIT slide 3.6% in the last twelve months. If that earnings trend continues then its debt load will grow heavy like the heart of a polar bear watching its sole cub. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Nabors Industries can strengthen its balance sheet over time.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we always check how much of that EBIT is translated into free cash flow. During the last two years, Nabors Industries produced sturdy free cash flow equating to 52% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.

Our View

On the face of it, Nabors Industries's interest cover left us tentative about the stock, and its level of total liabilities was no more enticing than the one empty restaurant on the busiest night of the year. But on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. We're quite clear that we consider Nabors Industries to be really rather risky, as a result of its balance sheet health. So we're almost as wary of this stock as a hungry kitten is about falling into its owner's fish pond: once bitten, twice shy, as they say. While Nabors Industries didn't make a statutory profit in the last year, its positive EBIT suggests that profitability might not be far away.
