South Korean battery materials maker POSCO Future M and Hyundai Motor Group have signed a letter of intent covering a synthetic graphite anode plant in Vietnam, with Hyundai weighing an equity stake worth 100 billion won, according to BusinessKorea and The Korea Herald. BusinessKorea converts that sum to about $72.7 million, while The Korea Herald puts it at roughly $74.4 million.

- POSCO Future M and Hyundai Motor Group signed a letter of intent on Nov. 3 covering a synthetic graphite anode project in Vietnam, according to BusinessKorea and The Korea Herald.
- Hyundai is considering an equity stake worth 100 billion won, reported as about $72.7 million by BusinessKorea and about $74.4 million by The Korea Herald.
- If the investment goes through, Hyundai would gain priority purchasing rights for anode material made at the plant.
- POSCO Future M has already begun building the facility in Thai Nguyen, Vietnam, and is aiming for mass production by 2028.
- The companies say this builds on a cooperation agreement from April of last year covering steel and battery materials.
What happened
The two companies finalized the agreement on Nov. 3, outlining Hyundai’s potential investment in POSCO Future M’s Vietnam-based synthetic graphite anode material business, both outlets reported. Should the investment proceed, Hyundai would be granted priority purchasing rights for the anode materials manufactured at the site. The firms also plan to work together on early-stage product development and quality testing aimed at meeting the demands of higher-performance electric vehicles, according to the reports.
Why it matters
Synthetic graphite anodes are valued in battery production because they can improve fast-charging ability and extend battery lifespan compared with natural graphite alternatives, per BusinessKorea. Securing a steady supply of this material has become more pressing as rules like the foreign entity of concern requirements in the United States and the European Union’s Industry Acceleration Act push companies to diversify where they source battery components, the outlet noted.
For POSCO Future M, bringing in a major automaker as an investor could help it move faster on expanding production capacity abroad. For Hyundai, locking in a supply line and buying priority for a key EV material could support its push to localize and secure battery inputs outside of existing supply chains.

Background
This latest step follows an earlier cooperation agreement the two companies struck in April of last year, which focused on joint work across steel production and secondary battery materials, according to BusinessKorea. The companies describe the new Vietnam initiative as part of a broader effort to deepen their partnership as global trade rules shift and industries adjust their supply networks.
POSCO Future M has already started construction on the anode plant in Thai Nguyen, Vietnam, with mass production targeted for 2028, per BusinessKorea’s reporting. The company says it has lined up customer contracts covering the first phase of investment and is now working on a second phase of funding for the project.
What to watch
Whether Hyundai’s roughly $74 million stake becomes final will depend on further steps beyond this letter of intent, which is a preliminary, non-binding agreement rather than a signed investment contract. Progress on POSCO Future M’s second-phase funding, along with how the Thai Nguyen plant’s construction timeline unfolds toward the 2028 production goal, will likely shape how this partnership develops.
Our read: the deal reflects a broader pattern among Korean manufacturers of locking in battery material supply through direct investment rather than relying solely on long-term purchase contracts, a response to tightening rules on where EV supply chains can source critical components.
