SEOUL, February 02 (AJP) - Samsung SDI swung to an operating loss in 2025 as a prolonged slowdown in electric-vehicle demand and shifting policy conditions in the United States and Europe weighed on performance, the battery maker said on Monday.

In a regulatory filing, the company reported an operating loss of 1.72 trillion won for the year, reversing an operating profit of 363.3 billion won in 2024. Revenue fell 20 percent to 13.27 trillion won from 16.6 trillion won a year earlier.

Fourth-quarter revenue reached 3.86 trillion won, up 26.4 percent from the previous quarter and 2.8 percent from a year earlier, while the operating loss narrowed to 299.2 billion won, roughly half the level recorded in the third quarter.

Battery sales totaled 3.6 trillion won in the quarter, rising 28.4 percent quarter on quarter and 1.6 percent year on year. The battery division posted an operating loss of 338.5 billion won.

Samsung SDI forecast that the global EV battery market excluding China will grow about 6 percent this year, citing looser green policies in North America and Europe and automakers’ adjustments to electrification strategies.

Demand for ESS batteries is expected to continue rising for power-grid applications and backup systems, supported by expanding investment in artificial intelligence data centers.
