Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 Shenzhen Highpower Technology Co., Ltd. (SZSE:001283) does use debt in its business. But should shareholders be worried about its use of debt?

When Is Debt A Problem?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. 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. 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 Shenzhen Highpower Technology's Debt?

You can click the graphic below for the historical numbers, but it shows that as of September 2024 Shenzhen Highpower Technology had CN¥2.30b of debt, an increase on CN¥1.20b, over one year. However, it also had CN¥1.16b in cash, and so its net debt is CN¥1.14b.

How Strong Is Shenzhen Highpower Technology's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Shenzhen Highpower Technology had liabilities of CN¥4.13b due within 12 months and liabilities of CN¥2.21b due beyond that. Offsetting this, it had CN¥1.16b in cash and CN¥1.83b in receivables that were due within 12 months. So its liabilities total CN¥3.35b more than the combination of its cash and short-term receivables.

This is a mountain of leverage relative to its market capitalization of CN¥4.00b. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe dilution.

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.

While Shenzhen Highpower Technology's debt to EBITDA ratio (3.7) suggests that it uses some debt, its interest cover is very weak, at 1.4, suggesting high leverage. It seems that the business incurs large depreciation and amortisation charges, so maybe its debt load is heavier than it would first appear, since EBITDA is arguably a generous measure of earnings. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. The good news is that Shenzhen Highpower Technology grew its EBIT a smooth 66% over the last twelve months. Like a mother's loving embrace of a newborn that sort of growth builds resilience, putting the company in a stronger position to manage its debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Shenzhen Highpower Technology's ability to maintain a healthy balance sheet going forward.

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. During the last three years, Shenzhen Highpower Technology burned a lot of cash. 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

To be frank both Shenzhen Highpower Technology's interest cover and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. But on the bright side, its EBIT growth rate is a good sign, and makes us more optimistic. Overall, we think it's fair to say that Shenzhen Highpower Technology has enough debt that there are some real risks around the balance sheet. If everything goes well that may pay off but the downside of this debt is a greater risk of permanent losses. 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. We've identified 3 warning signs with Shenzhen Highpower Technology (at least 2 which are concerning) , and understanding them should be part of your investment process.

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.
