The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says '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 LSB Industries, Inc. (NYSE:LXU) makes use of debt. But the real question is whether this debt is making the company risky.

What Risk Does Debt Bring?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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 think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does LSB Industries Carry?

As you can see below, LSB Industries had US$594.2m of debt at December 2023, down from US$727.3m a year prior. However, it also had US$305.9m in cash, and so its net debt is US$288.2m.

How Strong Is LSB Industries' Balance Sheet?

The latest balance sheet data shows that LSB Industries had liabilities of US$118.5m due within a year, and liabilities of US$661.3m falling due after that. On the other hand, it had cash of US$305.9m and US$40.4m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$433.5m.

This is a mountain of leverage relative to its market capitalization of US$621.9m. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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). 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 LSB Industries's debt is only 2.4, its interest cover is really very low at 2.0. 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. Shareholders should be aware that LSB Industries's EBIT was down 83% last year. If that decline continues then paying off debt will be harder than selling foie gras at a vegan convention. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine LSB Industries's ability to maintain a healthy balance sheet going forward.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, LSB Industries recorded free cash flow worth a fulsome 91% 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

On the face of it, LSB Industries's interest cover left us tentative about the stock, and its EBIT growth rate 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. Once we consider all the factors above, together, it seems to us that LSB Industries's debt is making it a bit risky. Some people like that sort of risk, but we're mindful of the potential pitfalls, so we'd probably prefer it carry less debt. 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. We've identified 3 warning signs with LSB Industries (at least 1 which doesn't sit too well with us) , and understanding them should be part of your investment process.

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.
