On 4 June 2026, Horizon Robotics filed a Next Day Disclosure Return with the Hong Kong Stock Exchange detailing an internal share-class conversion that modestly altered the composition—but not the total number—of its issued shares.

The company converted 11.62 million unlisted weighted‐voting‐right (WVR) Class A ordinary shares into listed WVR Class B ordinary shares. As a result, the outstanding Class B share count (excluding treasury shares) increased 0.09% to 12.46 billion, while the Class A share count fell 0.55% to 2.11 billion.

Treasury shares remained unchanged at 80.16 million, leaving the issuer’s overall share capital steady at 14.65 billion shares (inclusive of treasury shares). No new shares were issued, and no share repurchases or cancellations occurred in the period covered by the filing.

The board confirmed that the conversion complied with all relevant listing rules and regulatory requirements.
