Is SK Discovery (KRX:006120) Using Too Much Debt?

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.' 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, SK Discovery Co., Ltd. (KRX:006120) does carry debt. But is this debt a concern to shareholders?

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

What Risk Does Debt Bring?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. When we examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does SK Discovery Carry?

As you can see below, at the end of March 2025, SK Discovery had ₩5.66t of debt, up from ₩4.91t a year ago. Click the image for more detail. On the flip side, it has ₩2.93t in cash leading to net debt of about ₩2.73t.

How Healthy Is SK Discovery's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that SK Discovery had liabilities of ₩3.96t due within 12 months and liabilities of ₩5.10t due beyond that. Offsetting these obligations, it had cash of ₩2.93t as well as receivables valued at ₩1.27t due within 12 months. So it has liabilities totalling ₩4.85t more than its cash and near-term receivables, combined.

The deficiency here weighs heavily on the ₩903.9b company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we definitely think shareholders need to watch this one closely. At the end of the day, SK Discovery would probably need a major re-capitalization if its creditors were to demand repayment.

Check out our latest analysis for SK Discovery

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). 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 SK Discovery's debt to EBITDA ratio (4.2) suggests that it uses some debt, its interest cover is very weak, at 1.8, 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. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. However, it should be some comfort for shareholders to recall that SK Discovery actually grew its EBIT by a hefty 104%, over the last 12 months. If that earnings trend continues it will make its debt load much more manageable in the future. When analysing debt levels, the balance sheet is the obvious place to start. But you can't view debt in total isolation; since SK Discovery will need earnings to service that debt. So when considering debt, it's definitely worth looking at the earnings trend.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the last three years, SK Discovery 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 SK Discovery's conversion of EBIT to free cash flow and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. But on the bright side, its EBIT growth rate is a good sign, and makes us more optimistic. We're quite clear that we consider SK Discovery 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. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. Case in point: We've spotted 4 warning signs for SK Discovery you should be aware of, and 2 of them are concerning.
