Warren Buffett famously said, 'Volatility is far from synonymous with risk.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. As with many other companies Singapore Post Limited (SGX:S08) makes use of debt. But the real question is whether this debt is making the company risky.

When Is Debt Dangerous?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we think about a company's use of debt, we first look at cash and debt together.

What Is Singapore Post's Debt?

As you can see below, at the end of September 2023, Singapore Post had S$611.7m of debt, up from S$465.6m a year ago. Click the image for more detail. On the flip side, it has S$449.4m in cash leading to net debt of about S$162.3m.

A Look At Singapore Post's Liabilities

According to the last reported balance sheet, Singapore Post had liabilities of S$674.2m due within 12 months, and liabilities of S$713.2m due beyond 12 months. On the other hand, it had cash of S$449.4m and S$223.1m worth of receivables due within a year. So it has liabilities totalling S$714.9m more than its cash and near-term receivables, combined.

This is a mountain of leverage relative to its market capitalization of S$922.4m. 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).

While Singapore Post's low debt to EBITDA ratio of 1.2 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 4.8 times last year does give us pause. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. Unfortunately, Singapore Post's EBIT flopped 18% over the last four quarters. If earnings continue to decline at that rate then handling the debt will be more difficult than taking three children under 5 to a fancy pants restaurant. 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 Singapore Post'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 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. Over the last three years, Singapore Post recorded free cash flow worth a fulsome 82% 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

Neither Singapore Post's ability to grow its EBIT nor its level of total liabilities gave us confidence in its ability to take on more debt. But its conversion of EBIT to free cash flow tells a very different story, and suggests some resilience. Looking at all the angles mentioned above, it does seem to us that Singapore Post is a somewhat risky investment as a result of its debt. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. 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. These risks can be hard to spot. Every company has them, and we've spotted 1 warning sign for Singapore Post you should know about.
