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. Importantly, AAC Technologies Holdings Inc. (HKG:2018) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

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. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. When we think about a company's use of debt, we first look at cash and debt together.

What Is AAC Technologies Holdings's Debt?

The chart below, which you can click on for greater detail, shows that AAC Technologies Holdings had CN¥10.2b in debt in June 2022; about the same as the year before. However, it does have CN¥5.22b in cash offsetting this, leading to net debt of about CN¥4.98b.

How Strong Is AAC Technologies Holdings' Balance Sheet?

The latest balance sheet data shows that AAC Technologies Holdings had liabilities of CN¥7.98b due within a year, and liabilities of CN¥10.0b falling due after that. On the other hand, it had cash of CN¥5.22b and CN¥5.14b worth of receivables due within a year. So its liabilities total CN¥7.66b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because AAC Technologies Holdings is worth CN¥18.7b, and thus could probably raise enough capital to shore up 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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

While AAC Technologies Holdings's low debt to EBITDA ratio of 1.4 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 3.3 times last year does give us pause. So we'd recommend keeping a close eye on the impact financing costs are having on the business. Importantly, AAC Technologies Holdings's EBIT fell a jaw-dropping 51% in the last twelve months. If that earnings trend continues then paying off its debt will be about as easy as herding cats on to a roller coaster. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if AAC Technologies Holdings can strengthen its balance sheet over time. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. During the last three years, AAC Technologies Holdings burned a lot of cash. While that may be a result of expenditure for growth, it does make the debt far more risky.

Our View

To be frank both AAC Technologies Holdings's conversion of EBIT to free cash flow and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. But on the bright side, its net debt to EBITDA is a good sign, and makes us more optimistic. We're quite clear that we consider AAC Technologies Holdings to be really rather risky, as a result of its balance sheet health. So we're almost as wary of this stock as a hungry kitten is about falling into its owner's fish pond: once bitten, twice shy, as they say. 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.
