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.' 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. We can see that Kingfa Sci. & Tech. Co., Ltd. (SHSE:600143) does use debt in its business. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

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. 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, plenty of companies use debt to fund growth, without any negative consequences. When we examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does Kingfa Sci. & Tech Carry?

You can click the graphic below for the historical numbers, but it shows that Kingfa Sci. & Tech had CN¥26.8b of debt in June 2024, down from CN¥28.0b, one year before. On the flip side, it has CN¥3.37b in cash leading to net debt of about CN¥23.4b.

A Look At Kingfa Sci. & Tech's Liabilities

We can see from the most recent balance sheet that Kingfa Sci. & Tech had liabilities of CN¥21.4b falling due within a year, and liabilities of CN¥20.1b due beyond that. On the other hand, it had cash of CN¥3.37b and CN¥11.4b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by CN¥26.7b.

Given this deficit is actually higher than the company's market capitalization of CN¥19.5b, we think shareholders really should watch Kingfa Sci. & Tech's debt levels, like a parent watching their child ride a bike for the first time. In the scenario where the company had to clean up its balance sheet quickly, it seems likely shareholders would suffer extensive dilution.

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).

Weak interest cover of 1.3 times and a disturbingly high net debt to EBITDA ratio of 6.6 hit our confidence in Kingfa Sci. & Tech like a one-two punch to the gut. This means we'd consider it to have a heavy debt load. Even worse, Kingfa Sci. & Tech saw its EBIT tank 32% over the last 12 months. If earnings keep going like that over the long term, it has a snowball's chance in hell of paying off that 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 Kingfa Sci. & Tech's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Kingfa Sci. & Tech saw substantial negative free cash flow, in total. While investors are no doubt expecting a reversal of that situation in due course, it clearly does mean its use of debt is more risky.

Our View

On the face of it, Kingfa Sci. & Tech's conversion of EBIT to free cash flow left us tentative about the stock, and its EBIT growth rate was no more enticing than the one empty restaurant on the busiest night of the year. And even its net debt to EBITDA fails to inspire much confidence. Considering everything we've mentioned above, it's fair to say that Kingfa Sci. & Tech is carrying heavy debt load. If you play with fire you risk getting burnt, so we'd probably give this stock a wide berth. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it. For example, we've discovered 4 warning signs for Kingfa Sci. & Tech (2 are a bit concerning!) that you should be aware of before investing here.

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
