Legendary fund manager Li Lu (who Charlie Munger backed) once said, '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 SK Chemicals Co.,Ltd (KRX:285130) does have debt on its balance sheet. But should shareholders be worried about its use of debt?
Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. When we examine debt levels, we first consider both cash and debt levels, together.
You can click the graphic below for the historical numbers, but it shows that as of September 2025 SK ChemicalsLtd had ₩1.89t of debt, an increase on ₩1.58t, over one year. However, it does have ₩1.43t in cash offsetting this, leading to net debt of about ₩458.9b.
Zooming in on the latest balance sheet data, we can see that SK ChemicalsLtd had liabilities of ₩1.14t due within 12 months and liabilities of ₩1.46t due beyond that. On the other hand, it had cash of ₩1.43t and ₩347.7b worth of receivables due within a year. So it has liabilities totalling ₩822.3b more than its cash and near-term receivables, combined.
This deficit is considerable relative to its market capitalization of ₩1.36t, so it does suggest shareholders should keep an eye on SK ChemicalsLtd's use of debt. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.
Even though SK ChemicalsLtd's debt is only 2.4, its interest cover is really very low at 0.39. In large part that's it has so much depreciation and amortisation. These charges may be non-cash, so they could be excluded when it comes to paying down debt. But the accounting charges are there for a reason -- some assets are seen to be losing value. Either way there's no doubt the stock is using meaningful leverage. One redeeming factor for SK ChemicalsLtd is that it turned last year's EBIT loss into a gain of ₩10b, over the last twelve months. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine SK ChemicalsLtd's ability to maintain a healthy balance sheet going forward.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So it's worth checking how much of the earnings before interest and tax (EBIT) is backed by free cash flow. During the last year, SK ChemicalsLtd burned a lot of cash. While that may be a result of expenditure for growth, it does make the debt far more risky.
To be frank both SK ChemicalsLtd's interest cover and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. But at least its EBIT growth rate is not so bad. We're quite clear that we consider SK ChemicalsLtd to be really rather risky, as a result of its balance sheet health. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity. 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. Every company has them, and we've spotted 2 warning signs for SK ChemicalsLtd you should know about.
