General Motors is making another retreat from electric-vehicle battery investments by selling its 49.9% stake in an Indiana battery plant to South Korea’s Samsung SDI. The move comes as weaker EV demand forces automakers to rethink investments. The GM EV Battery Stake Deal With Samsung SDI marks GM’s second major pullback from EV batteries after a similar transaction with LG Energy Solution in 2025.
GM Exits Indiana Battery Venture
Samsung SDI announced Tuesday that it will take full control of the Indiana facility after acquiring GM’s stake in their joint venture. The companies announced the $3.5 billion partnership in August 2023, targeting production in 2027. Construction is underway.
The ownership change reflects weak EV demand. However, the deal does not end their relationship.
The companies have signed a new agreement to jointly develop next-generation prismatic battery cells. If finalized, the Indiana facility could manufacture these advanced cells for future GM electric vehicles.
Indiana Plant Pivots to Energy Storage
Samsung SDI now plans to target the growing U.S. stationary energy storage system (ESS) market. Demand is supported by solar, wind, and AI data centers.
GM and Ford are also expanding in ESS, a market led by Tesla. The strategy redirects investment toward stronger battery applications.
GM Stock Rises Despite EV Pullback
GM stock gained 1.6% to $89.36 in Tuesday trading. Shares cleared an 85.41 flat-base buy point on July 27 after a second-quarter earnings beat and raised outlook. GM remained near the upper end of its 5% buy zone, which extended to $89.68.
GM stock also broke a high-handle trendline, creating a potential entry around Monday’s $88.81 intraday high.
The deal comes as Ford and Tesla shares also gained less than 1%, although both remained below key moving averages. Ford faced renewed concerns after a sharp July sales decline, particularly involving EV demand. Tesla continues to face pressure from pricing, margins, and weaker China sales.
What the Deal Means for EVs
The GM EV Battery Stake Deal With Samsung SDI highlights an industry shift: automakers are becoming more selective about battery investments while pursuing energy-storage opportunities. For GM, the deal reduces exposure to uncertain EV demand without completely abandoning advanced battery technology.
The GM EV Battery Stake Deal With Samsung SDI represents both a retreat from near-term EV battery expansion and a bridge toward battery innovation.
