Samsung SDI said Friday its U.S. arm has won a battery supply contract without disclosing details, with the deal widely believed to be related to Tesla’s (TSLA) energy storage system business, Yonhap news reported.
The Korean battery maker said details of the agreement, including the amount, counterparty, and period, are being kept confidential for business reasons and that it will withhold further disclosure until January 2030, the report added.
The latest regulatory filing followed a separate announcement made in November 2025, in which Samsung SDI hinted it had been in talks to supply battery products to Tesla (TSLA).
