Rhea-AI Filing Summary

Ambarella CFO John Alexander Young reported a sale of 2,435 ordinary shares on June 17, 2025, at a price of $52.26 per share. The transaction was specifically executed to cover tax obligations arising from the vesting of restricted stock units (RSUs).

Following the reported transaction, Young continues to hold 111,451 shares directly. The Form 4 filing indicates this was a routine tax-related sale rather than a discretionary transaction, which is common practice among executives when RSUs vest.
