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.

Yes. A footnote explains that the reported options were granted under ECARX’s share incentive plans and that all of them had vested as of the Form 3 date, meaning they are fully earned and currently exercisable subject to their future expiration dates.

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

No buy or sell transactions are reported. The Form 3 is an initial statement of beneficial ownership listing vested option holdings, not new open-market trades. Transaction fields are classified as “holding” entries with unknown transaction codes and neutral net buy-sell direction.
