The South Korean battery maker disclosed Tuesday in a regulatory filing that revenue climbed 12.6 percent year-on-year to 3.576 trillion won, while net profit swung to a positive 56.1 billion won.
The battery segment, which accounts for the bulk of revenue at 3.354 trillion won, cut its operating loss by 61 percent as demand recovered across energy storage systems, power tools and battery backup units.
The electronics materials unit posted an operating profit of 21 billion won on revenue of 222 billion won, buoyed by resilient semiconductor materials sales and a rebound in display materials demand.
Samsung SDI said it secured a multi-year supply agreement with Mercedes-Benz during the quarter, completing its lineup of all three major German premium automakers as clients. The company also unveiled its first pouch-type all-solid-state battery sample developed for physical AI applications.
"Uncertainty in the global business environment is expected to persist into the second quarter," said a Samsung SDI spokesperson. "We will execute our response strategies by segment and work to achieve a quarterly profit turnaround in the second half."
The company said it expects upstream demand to continue recovering through the rest of the year, with ESS battery sales in the United States set to expand alongside growth in AI data center construction, while European EV demand is projected to improve on the back of broader subsidy programs.
Shares of Samsung SDI traded at 688,000 won per stock on 11:40 a.m., 8.35 percent higher than a day ago.
