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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. Importantly, Wolong Electric Group Co.,Ltd. (SHSE:600580) does carry debt. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. 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. When we think about a company's use of debt, we first look at cash and debt together.

What Is Wolong Electric GroupLtd's Net Debt?

As you can see below, Wolong Electric GroupLtd had CN¥6.25b of debt, at March 2024, which is about the same as the year before. You can click the chart for greater detail. However, it does have CN¥2.44b in cash offsetting this, leading to net debt of about CN¥3.81b.

How Healthy Is Wolong Electric GroupLtd's Balance Sheet?

According to the last reported balance sheet, Wolong Electric GroupLtd had liabilities of CN¥9.99b due within 12 months, and liabilities of CN¥3.90b due beyond 12 months. Offsetting this, it had CN¥2.44b in cash and CN¥6.72b in receivables that were due within 12 months. So it has liabilities totalling CN¥4.73b more than its cash and near-term receivables, combined.

Wolong Electric GroupLtd has a market capitalization of CN¥17.1b, so it could very likely raise cash to ameliorate 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.

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).

Wolong Electric GroupLtd's net debt is sitting at a very reasonable 2.2 times its EBITDA, while its EBIT covered its interest expense just 4.7 times last year. While these numbers do not alarm us, it's worth noting that the cost of the company's debt is having a real impact. Wolong Electric GroupLtd grew its EBIT by 4.5% in the last year. Whilst that hardly knocks our socks off it is a positive when it comes to debt. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Wolong Electric GroupLtd'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 we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Looking at the most recent three years, Wolong Electric GroupLtd recorded free cash flow of 22% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

Wolong Electric GroupLtd's struggle to convert EBIT to free cash flow had us second guessing its balance sheet strength, but the other data-points we considered were relatively redeeming. But on the bright side, its ability to to grow its EBIT isn't too shabby at all. Looking at all the angles mentioned above, it does seem to us that Wolong Electric GroupLtd is a somewhat risky investment as a result of its debt. Not all risk is bad, as it can boost share price returns if it pays off, but this debt risk is worth keeping in mind. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet.

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
