Japanese automaker Nissan (NSANY) finds itself at a crossroads. Nissan was poised to participate in a megamerger with rival Honda (HMC), and it was a huge development when the talks were revealed late last year.

Nissan’s decision to withdraw from merger discussions with Honda marks the latest setback for the struggling automaker as it faces declining sales, financial pressures, and an increasingly competitive electric vehicle (EV) market.

TOKYO — Nissan is set to call off merger talks with rival Honda, a source said Wednesday, abandoning a $60 billion-plus tie-up that would have created the world's No. 3 automaker and raising questions about how it will drive a turnaround by itself.
