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.' 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. Importantly, The Mosaic Company (NYSE:MOS) does carry debt. But the more important question is: how much risk is that debt creating?

Why Does Debt Bring Risk?

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. 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 Mosaic's Debt?

You can click the graphic below for the historical numbers, but it shows that as of March 2024 Mosaic had US$4.55b of debt, an increase on US$4.24b, over one year. However, it also had US$336.7m in cash, and so its net debt is US$4.22b.

How Strong Is Mosaic's Balance Sheet?

According to the last reported balance sheet, Mosaic had liabilities of US$4.02b due within 12 months, and liabilities of US$6.69b due beyond 12 months. On the other hand, it had cash of US$336.7m and US$1.47b worth of receivables due within a year. So it has liabilities totalling US$8.90b more than its cash and near-term receivables, combined.

Given this deficit is actually higher than the company's market capitalization of US$8.73b, we think shareholders really should watch Mosaic's debt levels, like a parent watching their child ride a bike for the first time. Hypothetically, extremely heavy dilution would be required if the company were forced to pay down its liabilities by raising capital at the current share price.

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).

Mosaic's net debt of 2.0 times EBITDA suggests graceful use of debt. And the fact that its trailing twelve months of EBIT was 7.3 times its interest expenses harmonizes with that theme. Importantly, Mosaic's EBIT fell a jaw-dropping 76% in the last twelve months. If that earnings trend continues then paying off its debt will be about as easy as herding cats on to a roller coaster. 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 Mosaic's ability to maintain a healthy balance sheet going forward. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So it's worth checking how much of that EBIT is backed by free cash flow. In the last three years, Mosaic's free cash flow amounted to 48% of its EBIT, less than we'd expect. That weak cash conversion makes it more difficult to handle indebtedness.

Our View

Mulling over Mosaic's attempt at (not) growing its EBIT, we're certainly not enthusiastic. But on the bright side, its interest cover is a good sign, and makes us more optimistic. Overall, we think it's fair to say that Mosaic has enough debt that there are some real risks around the balance sheet. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it.

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.
