Key Highlights
- Samsung SDI secures its inaugural electric vehicle battery supply agreement with Mercedes-Benz
- High-nickel NCM battery technology will power upcoming compact and midsize electric SUVs and coupes
- Deal estimated to exceed 10 trillion won (approximately $6.8 billion) with supply volumes reaching tens of GWh
- Samsung SDI shares climbed 4.87% following the announcement; Mercedes-Benz shares declined 2.49%
- Partnership expands Samsung SDI’s European automotive portfolio, joining existing clients BMW and Volkswagen
On Monday, Samsung SDI announced its maiden electric vehicle battery supply contract with Mercedes-Benz, triggering a 4.87% surge in its stock price. The landmark agreement was formalized during a signing ceremony held in Seoul, with senior leadership from both corporations in attendance.
The battery cells will incorporate high-nickel nickel-cobalt-manganese (NCM) technology. According to Samsung SDI, this advanced chemistry provides superior energy density, extended driving range, enhanced durability, and robust power performance.
Mercedes-Benz intends to integrate these battery systems into its forthcoming lineup of compact and midsize electric SUVs and coupe variants. Industry insiders indicate the batteries are designated for a new electric vehicle platform scheduled to debut in 2028.
While Samsung SDI refrained from publicly confirming the financial terms, industry analysts estimate supply volumes will reach tens of gigawatt-hours, with the total contract value surpassing 10 trillion won — equivalent to approximately $6.8 billion.
The Seoul ceremony featured Samsung SDI’s President and CEO Choi Joo-sun, alongside Mercedes-Benz Group Chair Ola Kallenius and Chief Technology Officer Jorg Burzer.
The Road to Partnership
This collaboration represents the culmination of extended negotiations. Samsung Electronics Chair Lee Jae-yong had been cultivating stronger connections with Mercedes-Benz over an extended period.
Last November, Kallenius traveled to South Korea for meetings with Lee at Samsung’s exclusive guest facility in Seoul. Their discussions centered on potential collaboration opportunities spanning automotive electronics and battery technologies.
The partnership gained traction following Lee’s trip to Germany, where he and Samsung SDI President Choi engaged in direct negotiations with Mercedes-Benz leadership.
The groundwork for this battery agreement was reinforced by Samsung’s pre-existing business relationship with Mercedes-Benz. Samsung’s subsidiary Harman currently provides the German automaker with infotainment systems and premium audio solutions.
For Mercedes-Benz, this agreement represents a strategic expansion of its battery supplier network, which already features Korean manufacturers LG Energy Solution and SK On. The automaker has been strategically diversifying its battery procurement channels in preparation for its next-generation electric vehicle production.
Strategic Implications for Samsung SDI
This contract positions Mercedes-Benz alongside Samsung SDI’s established European automotive partners, which include BMW and Volkswagen.
Samsung SDI emphasized that the battery systems will incorporate its exclusive safety innovations, which the company identified as a crucial competitive advantage in securing the partnership.
Beyond the immediate supply arrangement, both organizations confirmed their intention to extend collaboration into joint research and development of advanced battery technologies and future transportation solutions.
“This partnership brings together the innovative DNA of both companies,” a Samsung SDI official said.
Mercedes-Benz described the deal as ensuring “a stable supply of high-performance battery technology, a critical component of the brand’s electrification strategy.”
The substantial order volume is projected to significantly enhance Samsung SDI’s revenue generation and manufacturing capacity utilization. The multi-year contract targets production for Mercedes-Benz’s 2028 electric vehicle portfolio.
