[Q3] Company reports KRW 3.05 trillion ($ 2.13 billion) in revenue, and KRW 591.3 billion in operating loss
[Q4] Earnings expected to improve upon growth of energy storage system (ESS) market
Company aims to strengthen foundation for mid- and long-term growth by intensifying efforts to secure new orders for ESS and electric vehicle (EV) batteries
Samsung SDI today announced its financial results for the third quarter ended September 30, 2025.
The company posted quarterly revenue of KRW 3.05 trillion ($2.13 billion) and an operating loss of KRW 591.3 billion
The revenue declined by 4% from the previous quarter and 22.5% from a year earlier, while operating losses continued. However, the net profit for the third quarter swung to a surplus of KRW 5.7 billion, driven by gains from the discontinuation of the polarizer film business.
The battery business generated revenue of KRW 2.82 trillion, down 4.8% quarter-on-quarter and 23.2% year-on-year. It posted an operating loss of KRW 630.1 billion, which widened due to slower sales of EV batteries and the impact of the U.S. tariffs on ESS batteries.
The electronic materials business reported revenue of KRW 231.8 billion, up 6.2% from the previous quarter but down 12.1% year-on-year. Operating profit surged 17.6% to KRW 38.8 billion.
Business highlights for Third Quarter
Despite ongoing uncertainties in the business environment, Samsung SDI achieved significant progress by actively promoting sales of EV and ESS batteries during the July-September period.
The company secured multiple supply contracts totaling over 110 Gigawatt hours (GWh) with global automotive groups, covering both 46-series cylindrical and prismatic batteries. It also won the majority of deals in a large government-led ESS supply project.
Introducing Samsung Battery Box 1.7, featuring safety-enhanced prismatic NCA batteries, and SBB 2.0 based on prismatic LFP batteries to the U.S. market, the company is preparing to offer next-generation ESS products that will be manufactured locally in the U.S.
Business Outlook for the Fourth Quarter 2025
Despite the policy uncertainties expected to persist in the next quarter, Samsung SDI anticipates an earnings improvement driven by growth in the EV market in Europe and the ESS market in the U.S.
In particular, the company plans to concentrate its capabilities on the ESS market, strengthen its presence in the EV sector, and enhance operational efficiency.
The company, first of all, plans to better respond to the growing U.S. ESS market by establishing manufacturing facilities in the region. Earlier this month, the company started local production of NCA batteries for ESS at StarPlus Energy factory located in Indiana, its joint venture with automaker Stellantis.
It also plans to install lines for LFP batteries with mass production scheduled to begin in the fourth quarter of 2026. By around the end of next year, the company’s annual ESS battery capacity in the U.S. is expected to reach 30 GWh.
Samsung SDI, currently the only prismatic battery supplier among non-Chinese battery makers, expects its competitiveness in the U.S. ESS market to further strengthen, given the growing preference for prismatic batteries due to their safety and high energy density features.
For EV batteries, Samsung SDI will continue to secure new projects with its high-nickel 46-series cylindrical cells and prismatic batteries, as well as LFP and mid-nickel batteries targeting the affordable segment. In response to the growing orders for hybrid vehicles, the company will move to supply tabless cylindrical batteries, diversifying its sales portfolio.
By swiftly responding to market changes, Samsung will strive to enhance its business performance and build a solid foundation for long-term growth.
