Corporate Governance Expert

TL;DR: The joint filing documents compliance but conveys no governance influence by the reporting Bosch entities.

The reporting entities executed a joint filing agreement and certified the statement, which demonstrates procedural compliance with beneficial ownership disclosure rules. Because both entities report zero voting and dispositive power, the filing indicates they do not exercise control or voting influence over Hesai Group through Class B ordinary shares. Sections on group membership, subsidiaries, and holdings on behalf of others are marked not applicable, reinforcing that this filing does not change governance dynamics.
