Legendary fund manager Li Lu (who Charlie Munger backed) once said, 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' 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. Importantly, Mermaid Maritime Public Company Limited (SGX:DU4) 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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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, 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.

What Is Mermaid Maritime's Debt?

You can click the graphic below for the historical numbers, but it shows that as of March 2024 Mermaid Maritime had US$87.2m of debt, an increase on US$45.5m, over one year. However, because it has a cash reserve of US$23.6m, its net debt is less, at about US$63.6m.

A Look At Mermaid Maritime's Liabilities

Zooming in on the latest balance sheet data, we can see that Mermaid Maritime had liabilities of US$161.2m due within 12 months and liabilities of US$34.2m due beyond that. Offsetting these obligations, it had cash of US$23.6m as well as receivables valued at US$142.5m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$29.3m.

Of course, Mermaid Maritime has a market capitalization of US$190.6m, so these liabilities are probably manageable. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Mermaid Maritime has net debt worth 1.9 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 3.5 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. Pleasingly, Mermaid Maritime is growing its EBIT faster than former Australian PM Bob Hawke downs a yard glass, boasting a 162% gain in the last twelve months. When analysing debt levels, the balance sheet is the obvious place to start. But it is Mermaid Maritime's earnings that will influence how the balance sheet holds up in the future. So when considering debt, it's definitely worth looking at the earnings trend. Click here for an interactive snapshot.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. In the last two years, Mermaid Maritime created free cash flow amounting to 14% of its EBIT, an uninspiring performance. For us, cash conversion that low sparks a little paranoia about is ability to extinguish debt.

Our View

When it comes to the balance sheet, the standout positive for Mermaid Maritime was the fact that it seems able to grow its EBIT confidently. However, our other observations weren't so heartening. For example, its conversion of EBIT to free cash flow makes us a little nervous about its debt. When we consider all the elements mentioned above, it seems to us that Mermaid Maritime is managing its debt quite well. But a word of caution: we think debt levels are high enough to justify ongoing monitoring. 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 - Mermaid Maritime has 1 warning sign we think you should be aware of.
