Is Cosan (BVMF:CSAN3) A Risky Investment?

Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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, Cosan S.A. (BVMF:CSAN3) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt Dangerous?

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 frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Cosan's Net Debt?

The image below, which you can click on for greater detail, shows that at March 2023 Cosan had debt of R$52.6b, up from R$40.1b in one year. However, because it has a cash reserve of R$14.6b, its net debt is less, at about R$38.0b.

A Look At Cosan's Liabilities

The latest balance sheet data shows that Cosan had liabilities of R$16.9b due within a year, and liabilities of R$67.5b falling due after that. Offsetting this, it had R$14.6b in cash and R$6.00b in receivables that were due within 12 months. So its liabilities total R$63.8b more than the combination of its cash and short-term receivables.

The deficiency here weighs heavily on the R$36.1b 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. After all, Cosan would likely require a major re-capitalisation if it had to pay its creditors today.

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).

While we wouldn't worry about Cosan's net debt to EBITDA ratio of 4.3, we think its super-low interest cover of 2.1 times is a sign of high leverage. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Looking on the bright side, Cosan boosted its EBIT by a silky 58% in the last year. Like a mother's loving embrace of a newborn that sort of growth builds resilience, putting the company in a stronger position to manage its debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Cosan'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.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the most recent three years, Cosan recorded free cash flow worth 66% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

On the face of it, Cosan'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 at least it's pretty decent at growing its EBIT; that's encouraging. Once we consider all the factors above, together, it seems to us that Cosan'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. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. For example Cosan has 2 warning signs (and 1 which is potentially serious) we think you should know about.
