Is KT (KRX:030200) Using Too Much Debt?

Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that '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. As with many other companies KT Corporation (KRX:030200) makes use of debt. But the real question is whether this debt is making the company risky.

What Risk Does Debt Bring?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. 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, 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 KT Carry?

As you can see below, at the end of September 2025, KT had ₩11t of debt, up from ₩9.77t a year ago. Click the image for more detail. However, because it has a cash reserve of ₩5.29t, its net debt is less, at about ₩5.24t.

How Strong Is KT's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that KT had liabilities of ₩12t due within 12 months and liabilities of ₩12t due beyond that. On the other hand, it had cash of ₩5.29t and ₩3.23t worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by ₩15t.

Given this deficit is actually higher than the company's market capitalization of ₩13t, we think shareholders really should watch KT's debt levels, like a parent watching their child ride a bike for the first time. In the scenario where the company had to clean up its balance sheet quickly, it seems likely shareholders would suffer extensive dilution.

Check out our latest analysis for KT

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).

KT's net debt is only 1.0 times its EBITDA. And its EBIT easily covers its interest expense, being 52.1 times the size. So you could argue it is no more threatened by its debt than an elephant is by a mouse. On the other hand, KT saw its EBIT drop by 7.9% in the last twelve months. That sort of decline, if sustained, will obviously make debt harder to handle. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if KT can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the most recent three years, KT recorded free cash flow worth 74% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

We feel some trepidation about KT's difficulty level of total liabilities, but we've got positives to focus on, too. For example, its interest cover and conversion of EBIT to free cash flow give us some confidence in its ability to manage its debt. Looking at all the angles mentioned above, it does seem to us that KT is a somewhat risky investment as a result of its debt. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. 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. For example - KT has 1 warning sign we think you should be aware of.

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
