Lou Tiancheng 4

What Happened
Lou Tiancheng, Pony AI's Chief Technology Officer and a director, had 31,250 restricted stock units (RSUs) vest on March 25, 2026. The vested RSUs were converted/exercised and immediately disposed to the issuer in a cash settlement — 31,250 shares at $11.39 per share, generating $355,938 in proceeds. The RSUs were settled in cash under the company's 2016 share incentive plan, so no Class A shares were added to his holdings.

Context
This was a cash settlement of vested RSUs (a form of compensation), not an open-market sale of existing holdings. Such cash-in-lieu settlements are common for executives and do not necessarily signal a change in sentiment. For retail investors, purchases generally carry more informational weight than routine cash settlements or company-plan dispositions.
