Samsung SDI Sells Display Stake to Fund US Battery Plant Expansion

Samsung SDI will gain full control of the New Carlisle, Indiana ESS venture by buying General Motors’ stake in the Synergy Cells project, turning the $3.5 billion facility under SDI’s leadership.
Samsung SDI will transfer 13,088,235 Samsung Display shares (about 33% of its Samsung Display stake) to Samsung Display for roughly 4.45 trillion won, reducing its ownership to 10.22%; Samsung Display plans to repurchase the shares as treasury stock, with the deal expected to close on August 27 and final counts/value subject to adjustment.
The proceeds are earmarked to fund growth investments, including facility upgrades and new battery plants in the United States such as the New Carlisle project, while Samsung SDI maintains a meaningful (though reduced) minority stake in Samsung Display.
Samsung SDI executives indicate the cash from the stake sale will enable aggressive investments for future growth and bolster the company’s financial health amid evolving demand in areas like energy storage, AI-related data centers, humanoids, and aerospace.
Samsung SDI is selling roughly $3.2 billion of its stake in Samsung Display to fund aggressive expansion into batteries for AI data centers and energy storage Korea Herald.

The company is targeting AI data centers, humanoid robots, and aerospace—sectors projected to explode over the next five years.
By selling its Samsung Display stake now, Samsung SDI strengthens its balance sheet for capital-intensive battery manufacturing BigGo Finance. The strategy amounts to a long-term bet: sacrifice dividends today to own critical capacity in tomorrow's high-growth markets. Energy storage alone is expected to grow 30%+ annually through 2030.
