Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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. As with many other companies WLS Holdings Limited (HKG:8021) makes use of debt. But the more important question is: how much risk is that debt creating?

Why Does Debt Bring Risk?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is WLS Holdings's Debt?

As you can see below, WLS Holdings had HK$143.2m of debt at April 2022, down from HK$153.8m a year prior. However, because it has a cash reserve of HK$108.1m, its net debt is less, at about HK$35.1m.

How Healthy Is WLS Holdings' Balance Sheet?

We can see from the most recent balance sheet that WLS Holdings had liabilities of HK$194.9m falling due within a year, and liabilities of HK$5.92m due beyond that. Offsetting this, it had HK$108.1m in cash and HK$300.2m in receivables that were due within 12 months. So it actually has HK$207.6m more liquid assets than total liabilities.

This surplus suggests that WLS Holdings is using debt in a way that is appears to be both safe and conservative. Given it has easily adequate short term liquidity, we don't think it will have any issues with its lenders.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While WLS Holdings has a quite reasonable net debt to EBITDA multiple of 1.7, its interest cover seems weak, at 2.4. This does have us wondering if the company pays high interest because it is considered risky. Either way there's no doubt the stock is using meaningful leverage. Shareholders should be aware that WLS Holdings's EBIT was down 46% last year. If that decline continues then paying off debt will be harder than selling foie gras at a vegan convention. When analysing debt levels, the balance sheet is the obvious place to start. But you can't view debt in total isolation; since WLS Holdings will need earnings to service that debt. So when considering debt, it's definitely worth looking at the earnings trend. Click here for an interactive snapshot.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, WLS Holdings 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

To be frank both WLS 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 level of total liabilities is a good sign, and makes us more optimistic. Looking at the balance sheet and taking into account all these factors, we do believe that debt is making WLS Holdings stock a bit risky. Some people like that sort of risk, but we're mindful of the potential pitfalls, so we'd probably prefer it carry less debt. 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. These risks can be hard to spot.
