Here's Why STO (KOSDAQ:098660) Has A Meaningful Debt Burden

The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' 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 note that STO Co., Ltd. (KOSDAQ:098660) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?

What Risk Does Debt Bring?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

How Much Debt Does STO Carry?

The image below, which you can click on for greater detail, shows that STO had debt of ₩19.5b at the end of September 2020, a reduction from ₩20.5b over a year. However, because it has a cash reserve of ₩3.70b, its net debt is less, at about ₩15.8b.

A Look At STO's Liabilities

According to the last reported balance sheet, STO had liabilities of ₩29.7b due within 12 months, and liabilities of ₩11.4b due beyond 12 months. Offsetting this, it had ₩3.70b in cash and ₩6.16b in receivables that were due within 12 months. So its liabilities total ₩31.2b more than the combination of its cash and short-term receivables.

This deficit is considerable relative to its market capitalization of ₩36.0b, so it does suggest shareholders should keep an eye on STO's use of debt. 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 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. 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. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. Even worse, STO saw its EBIT tank 55% over the last 12 months. If earnings keep going like that over the long term, it has a snowball's chance in hell of paying off that debt. 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 we always check how much of that EBIT is translated into free cash flow. Happily for any shareholders, STO actually produced more free cash flow than EBIT over the last three years. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.

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 on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. Once we consider all the factors above, together, it seems to us that STO's debt is making it a bit risky. That's not necessarily a bad thing, but we'd generally feel more comfortable with less leverage. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet. These risks can be hard to spot. Every company has them, and we've spotted 7 warning signs for STO (of which 2 are concerning!) you should know about.
