Is STO (KOSDAQ:098660) A Risky Investment?

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. Importantly, STO Co., Ltd. (KOSDAQ:098660) does carry debt. But should shareholders be worried about its use of debt?

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. 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 STO Carry?

The image below, which you can click on for greater detail, shows that at September 2024 STO had debt of ₩28.0b, up from ₩17.2b in one year. However, it does have ₩8.93b in cash offsetting this, leading to net debt of about ₩19.1b.

How Healthy Is STO's Balance Sheet?

We can see from the most recent balance sheet that STO had liabilities of ₩33.4b falling due within a year, and liabilities of ₩19.6b due beyond that. On the other hand, it had cash of ₩8.93b and ₩2.96b worth of receivables due within a year. So it has liabilities totalling ₩41.1b more than its cash and near-term receivables, combined.

When you consider that this deficiency exceeds the company's ₩35.1b market capitalization, you might well be inclined to review the balance sheet intently. In the scenario where the company had to clean up its balance sheet quickly, it seems likely shareholders would suffer extensive dilution.

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 STO's debt to EBITDA ratio (2.9) suggests that it uses some debt, its interest cover is very weak, at 0.86, suggesting high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Even worse, STO saw its EBIT tank 58% 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. The balance sheet is clearly the area to focus on when you are analysing debt. But you can't view debt in total isolation; since STO will need earnings to service that debt. 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, 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, STO actually produced more free cash flow than EBIT. That sort of strong cash conversion gets us as excited as the crowd when the beat drops at a Daft Punk concert.

Our View

On the face of it, STO's interest cover 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. 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 all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. For example, we've discovered 3 warning signs for STO (2 shouldn't be ignored!) that you should be aware of before investing here.

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.
