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. We can see that SMU S.A. (SNSE:SMU) does use debt in its business. But should shareholders be worried about its use of debt?
Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. If things get really bad, the lenders can take control of the business. 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, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.
The image below, which you can click on for greater detail, shows that SMU had debt of CL$489.9b at the end of September 2025, a reduction from CL$601.7b over a year. However, it does have CL$80.0b in cash offsetting this, leading to net debt of about CL$409.9b.
According to the last reported balance sheet, SMU had liabilities of CL$552.0b due within 12 months, and liabilities of CL$1.11t due beyond 12 months. Offsetting this, it had CL$80.0b in cash and CL$88.7b in receivables that were due within 12 months. So its liabilities total CL$1.50t more than the combination of its cash and short-term receivables.
This deficit casts a shadow over the CL$943.9b company, like a colossus towering over mere mortals. So we definitely think shareholders need to watch this one closely. After all, SMU 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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.
While we wouldn't worry about SMU's net debt to EBITDA ratio of 2.7, we think its super-low interest cover of 1.9 times is a sign of high leverage. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. Investors should also be troubled by the fact that SMU saw its EBIT drop by 19% over the last twelve months. If things keep going like that, handling the debt will about as easy as bundling an angry house cat into its travel box. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine SMU's ability to maintain a healthy balance sheet going forward.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Happily for any shareholders, SMU actually produced more free cash flow than EBIT over the last three years. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.
To be frank both SMU's EBIT growth rate and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. 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 SMU to be really rather risky, as a result of its balance sheet health. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity. 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 instance, we've identified 3 warning signs for SMU (2 don't sit too well with us) you should be aware of.
