Seoul, Feb 2 (NationPress) On Monday, Samsung SDI announced that it continued to face challenges in the fourth quarter of 2025, primarily due to weak demand for electric vehicles in the United States. Despite this, the company’s energy storage system (ESS) business helped mitigate the losses.

For the October-December period, net profit was recorded at 207.8 billion won ($142.4 million), a recovery from a loss of 242.7 billion won during the same timeframe in 2024, according to a regulatory filing reported by Yonhap news agency.

Samsung SDI's operating loss for the fourth quarter reached 299.2 billion won, compared to 256.7 billion won in losses from the previous year. Sales improved by 2.8% to 3.85 trillion won.

In terms of specific sectors, the battery division incurred an operating loss of 338.5 billion won, while the electronic materials segment achieved an operating profit of 39.3 billion won.

Within the battery sector, Samsung SDI highlighted that its ESS business reached its highest quarterly revenue ever, and benefits from the U.S. Advanced Manufacturing Production Credit (AMPC) played a role in reducing losses.

For the entirety of 2025, Samsung SDI reported a net loss of 584.9 billion won, a stark contrast to a net profit of 575.5 billion won the year prior.

The company’s annual operating loss was 1.72 trillion won, in contrast to a profit of 363.3 billion won the previous year, with total sales declining by 20% to 13.26 trillion won.

Despite facing significant hurdles last year, such as policy shifts in key markets and reduced EV demand from major U.S. clients, Samsung SDI secured substantial orders from global customers by enhancing its overseas sales efforts in the ESS market.

Samsung SDI has also focused on improving its technological edge by collaborating with Germany's BMW AG to test all-solid-state battery technology and has signed an agreement with Hyundai Motor Group to create batteries for robotics.

Looking forward, Samsung SDI anticipates ongoing growth in the ESS market, driven by strong demand from the artificial intelligence (AI) sector.

The small battery market is predicted to rebound, spurred by the demand from professional power tools as the construction of AI data centers speeds up, with additional growth expected in emerging fields like robotics.

“By concentrating on enhancing management efficiency, responding swiftly to customer needs and market trends, and preparing for future technologies, we aim to turn this year into a pivotal moment for a complete business comeback,” the company stated.
