Nissan is considering reaching a final agreement this week on a review of its alliance with French partner Renault.

The Japanese automaker is expected to seek an agreement after its board meets as early as Thursday to discuss its planned investment in Ampere, Renault's new electric vehicle subsidiary, which is key to the partnership talks.

It also hopes to conclude a final contract with the French automaker to achieve an equal capital relationship.

The two sides agreed in February to reduce Renault's stake in Nissan from 43% to 15%. A final contract on the matter was initially expected for late March, but has been delayed.

They have been negotiating on Nissan's investment in Ampere at the same time, and working out details on that matter is expected to help conclude the final contract.

Renault plans to take Ampere public. The EV unit's listing was initially expected for the second half of 2023, but is now expected for 2024.

In February, it was announced that Nissan would take a stake of up to 15% in Ampere. But the actual amount of the Japanese automaker's investment will depend on a myriad of factors, such as Ampere's market capitalization when it goes public and issues related to intellectual property.

As there are many uncertain factors, including the initial market cap, the Nissan board is considering presenting more detailed ways to invest in Ampere, rather than finalizing the size of its investment now.
