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.

Since the dramatic downfall of “Cost Killer” chief executive Carlos Ghosn in 2018, Japan’s Nissan Motor Co. has labored with weak sales and an outdated model lineup.

Nissan and Honda stated on Wednesday that discussions on various options, including ending merger talks, are still in progress. Ending talks would cost Nissan ¥100 billion, or $657 million.
