SK Chemicals of South Korea reported third-quarter revenue of 402.1 billion South Korean won (approximately $301 million) and an operating profit of 16.4 billion won. Revenue rose 8.2% year-over-year, while operating profit declined 45% compared to the same period last year. The company stated that the drop in profit was driven by a deteriorating external environment across the chemical industry, including rising raw material costs, a weaker exchange rate, and oil price volatility.
