Honda's U.S.-listed shares popped Monday morning after the Japanese automaker and Nissan announced plans to merge in 2026.

The proposed deal aims to unify operations under a joint holding company, led by Honda, while maintaining the distinct identities of each brand, according to Honda's president, Toshihiro Mibe. If finalized, the merger would position the combined entity to better compete with market leaders Toyota and Volkswagen.

Japan’s second- and third-largest automakers hope the $50 billion deal would help them catch up with Tesla and China’s BYD in electric vehicles and advanced software.

Honda and Nissan have acknowledged the possibility of a merger, driving an active trading session in Tokyo for the Japanese auto makers.

Together, Honda and Nissan would also pose more of a threat to Toyota Motor Corp., which is the world’s biggest automaker followed by Volkswagen AG.

Toyota Motor plans to increase its return on equity to compete globally, reports said Wednesday. Earlier this week, Honda Motor and Nissan confirmed they are in talks about a possible merger at time of auto industry upheaval.

Honda's acquisition of Nissan could strengthen the two struggling brands to better compete with China's BYD Co. in the global auto market. Honda's planned acquisition of Nissan would combine their more than 6 million global sales in 2024,

Analysts questioned the timing of the Honda-Nissan potential deal amid intense competition from Chinese rivals, reported the news agency Reuters.
