STO (KOSDAQ:098660) Takes On Some Risk With Its Use Of Debt

Warren Buffett famously said, 'Volatility is far from synonymous with risk.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. As with many other companies STO Co., Ltd. (KOSDAQ:098660) 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. If things get really bad, the lenders can take control of the business. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. 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.

How Much Debt Does STO Carry?

You can click the graphic below for the historical numbers, but it shows that STO had ₩19.5b of debt in September 2020, down from ₩20.5b, one year before. However, it does have ₩3.70b in cash offsetting this, leading to net debt of about ₩15.8b.

How Strong Is STO's Balance Sheet?

The latest balance sheet data shows that STO had liabilities of ₩29.7b due within a year, and liabilities of ₩11.4b falling due after that. On the other hand, it had cash of ₩3.70b and ₩6.16b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by ₩31.2b.

Given this deficit is actually higher than the company's market capitalization of ₩25.2b, we think shareholders really should watch STO's debt levels, like a parent watching their child ride a bike for the first time. Hypothetically, extremely heavy dilution would be required if the company were forced to pay down its liabilities by raising capital at the current share price.

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). 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).

While we wouldn't worry about STO's net debt to EBITDA ratio of 2.8, we think its super-low interest cover of 1.8 times is a sign of 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. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Even worse, STO saw its EBIT tank 55% over the last 12 months. If earnings continue to follow that trajectory, paying off that debt load will be harder than convincing us to run a marathon in the rain. There's no doubt that we learn most about debt from the balance sheet. But it is STO's earnings that will influence how the balance sheet holds up in the future. So if you're keen to discover more about its earnings, it might be worth checking out this graph of its long term earnings trend.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, STO actually produced more free cash flow than EBIT. There's nothing better than incoming cash when it comes to staying in your lenders' good graces.

Our View

To be frank both STO's interest cover and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. But at least it's pretty decent at converting EBIT to free cash flow; that's encouraging. Looking at the bigger picture, it seems clear to us that STO's use of debt is creating risks for the company. If everything goes well that may pay off but the downside of this debt is a greater risk of permanent losses. 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. Like risks, for instance. Every company has them, and we've spotted 6 warning signs for STO (of which 2 are potentially serious!) you should know about.
