The signing of an NDA between Shenzhen Jiuzi and Maigesong Electric for M&A negotiations is a significant step towards a potential merger. This move could be seen positively by the market as it indicates strategic growth and expansion efforts by JZXN. The protection of commercial secrets and sensitive information during the negotiation process also adds a layer of confidence in the smooth progression of the M&A, potentially leading to a positive short-term impact on JZXN's stock price.
