Shares of SES AI shares climbed after the South Korean artificial-intelligence battery company said it was partnering with Top Material to ramp up cell manufacturing in South Korea for drones and urban air mobility applications.
Shares were up 8.5% at $1.97. The stock has fallen 10% this year.
SES said Thursday that the collaboration with Top Material, a South Korean technology company, would take place at SES's existing factory in Chungju. It said the collaboration would lay the foundation for U.S. National Defense Authorization Act compliance.
The company said it had entered into a non-binding agreement with Top Material, with a definitive agreement expected in the first quarter of 2026.
