SK Innovation Reports Widened Annual Loss, Posts Q4 Operating Profit

SK Innovation Co. reported a widened annual net loss of 1.87 trillion won ($1.39 billion) for fiscal 2025, though it posted a fourth-quarter operating profit of 216.7 billion won. The South Korean energy group's performance reflects ongoing challenges in its battery and petroleum segments amid market volatility. Annual revenue declined to 73.97 trillion won from 78.86 trillion won a year earlier. The company attributed the annual loss to valuation losses on inventory and increased raw material costs, while the quarterly profit improvement stemmed from stronger margins in its lubricants business and reduced battery losses.
