Is Rumo (BVMF:RAIL3) 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.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. As with many other companies Rumo S.A. (BVMF:RAIL3) makes use of 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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Rumo's Net Debt?

The chart below, which you can click on for greater detail, shows that Rumo had R$18.0b in debt in March 2023; about the same as the year before. On the flip side, it has R$7.23b in cash leading to net debt of about R$10.8b.

A Look At Rumo's Liabilities

We can see from the most recent balance sheet that Rumo had liabilities of R$4.98b falling due within a year, and liabilities of R$25.0b due beyond that. Offsetting these obligations, it had cash of R$7.23b as well as receivables valued at R$1.19b due within 12 months. So it has liabilities totalling R$21.6b more than its cash and near-term receivables, combined.

This deficit isn't so bad because Rumo is worth R$41.5b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

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).

Rumo has net debt worth 2.4 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 4.0 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. Importantly, Rumo grew its EBIT by 73% 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 Rumo can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So it's worth checking how much of that EBIT is backed by free cash flow. In the last three years, Rumo's free cash flow amounted to 37% of its EBIT, less than we'd expect. That's not great, when it comes to paying down debt.

Our View

On our analysis Rumo's EBIT growth rate should signal that it won't have too much trouble with its debt. But the other factors we noted above weren't so encouraging. For instance it seems like it has to struggle a bit to cover its interest expense with its EBIT. Looking at all this data makes us feel a little cautious about Rumo's debt levels. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. 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.
