Recommendation

The partnership with Mercedes-Benz is a significant validation, but the company is still in the testing and scaling phase. The planned Nasdaq listing introduces execution risk and the need for further capital. A 'hold' position allows investors to monitor the progress of technology validation, manufacturing scale-up, and the successful completion of the business combination before considering a stronger conviction.
