FAQ

What does ZHANG XINGSHENG’s Form 3 filing for ECARX (ECX) show?

The Form 3 shows ZHANG XINGSHENG’s initial holdings of vested share options in ECARX. These options were granted under company incentive plans and give him rights to acquire Class A ordinary shares at a fixed price over several future years.

How many ECARX (ECX) shares are covered by ZHANG XINGSHENG’s options?

The filing lists three vested option grants covering 46,952, 123,362 and 101,266 underlying Class A ordinary shares. Each grant represents a separate block of options with its own expiration date, forming part of his overall equity-based compensation package.

What is the exercise price of the ECARX (ECX) options held by ZHANG XINGSHENG?

All listed options have an exercise price of $0.5000 per Class A ordinary share. This means he can purchase shares at that fixed price, subject to exercising the options before they expire on the respective dates disclosed in the filing.

The options reported in the Form 3 expire on December 31, 2033, December 31, 2034 and December 31, 2035. Each grant has its own expiration date, defining how long he has the right to exercise those particular options.

Does ZHANG XINGSHENG’s ECARX (ECX) Form 3 show any recent share purchases or sales?
