The Impact Of Unusual Items On Profit

For anyone who wants to understand SK ChemicalsLtd's profit beyond the statutory numbers, it's important to note that during the last twelve months statutory profit gained from ₩40b worth of unusual items. We can't deny that higher profits generally leave us optimistic, but we'd prefer it if the profit were to be sustainable. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. And, after all, that's exactly what the accounting terminology implies. SK ChemicalsLtd had a rather significant contribution from unusual items relative to its profit to September 2025. All else being equal, this would likely have the effect of making the statutory profit a poor guide to underlying earnings power.

An Unusual Tax Situation

Having already discussed the impact of the unusual items, we should also note that SK ChemicalsLtd received a tax benefit of ₩60b. This is meaningful because companies usually pay tax rather than receive tax benefits. We're sure the company was pleased with its tax benefit. And since it previously lost money, it may well simply indicate the realisation of past tax losses. However, the devil in the detail is that these kind of benefits only impact in the year they are booked, and are often one-off in nature. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal. While we think it's good that the company has booked a tax benefit, it does mean that there's every chance the statutory profit will come in a lot higher than it would be if the income was adjusted for one-off factors.

Our Take On SK ChemicalsLtd's Profit Performance

In the last year SK ChemicalsLtd received a tax benefit, which boosted its profit in a way that might not be much more sustainable than turning prime farmland into gas fields. And on top of that, it also saw an unusual item boost its profit, suggesting that next year might see a lower profit number, if these events are not repeated. On reflection, the above-mentioned factors give us the strong impression that SK ChemicalsLtd'sunderlying earnings power is not as good as it might seem, based on the statutory profit numbers. Keep in mind, when it comes to analysing a stock it's worth noting the risks involved. Case in point: We've spotted 2 warning signs for SK ChemicalsLtd you should be aware of.
