Hanwha Solutions said on Wednesday it posted 3.78 trillion won in revenue and an operating loss of 478.3 billion won in the fourth quarter of 2025. Revenue fell 18.6 percent from a year earlier and operating profit swung to a loss.

In the renewable energy business, solar module sales fell due to the impact of customs clearance delays. In the chemical business, profitability worsened as international trading prices for major products fell amid an oversupply phase in the market.

Full-year 2025 results were revenue of 13.35 trillion won and an operating loss of 353.3 billion won. Revenue rose 7.8 percent from a year earlier, while the operating loss increased 17.7 percent.

By business segment, renewable energy posted revenue of 6.86 trillion won and an operating loss of 85.2 billion won. It achieved record revenue as its U.S. residential energy business expanded. The loss narrowed from a year earlier. The chemical segment posted revenue of 4.62 trillion won and an operating loss of 249.1 billion won.

The advanced materials segment posted revenue of 1.11 trillion won and operating profit of 6.2 billion won. It reflected cost increases driven by a burden of fixed costs. It also began full-scale operations at a new solar materials plant in the United States, marking a second straight year of revenue topping 1 trillion won.

Jung Won-young (정원영), Hanwha Solutions' chief financial officer, said, "We expect normal operations and higher sales volume at the U.S. module plant in the first quarter, and we also expect selling prices to rise, so we forecast the renewable energy segment will return to operating profit." He added of the chemical segment, "We expect the loss to narrow due to base effects such as scheduled maintenance."
