Overview
- Samsung SDI said Tuesday it will acquire General Motors’ 49.99% stake in the $3.5 billion Synergy Cells joint venture, converting the project into a wholly owned Samsung SDI unit.
- The company did not disclose the purchase price or an expected closing date, and said the plant will become its first wholly owned battery factory in North America once the transaction completes.
- Samsung SDI plans to add production lines for energy storage system (ESS) batteries at the Indiana site to meet stronger near‑term demand for stationary storage.
- Both firms signed a joint development agreement to co-develop next‑generation prismatic EV cells, preserving technical cooperation and a potential future supply relationship despite GM’s equity exit.
- The move follows weaker U.S. EV demand after the end of the $7,500 federal tax credit and fits a wider pattern of automakers scaling back owned battery investments; the New Carlisle site has a finished building but no installed production equipment and its mass‑production timeline and job outcomes remain uncertain.
