Harbin Electric Company Limited will convene an H-Shares Class Meeting on 22 May 2026 at 9:30 a.m. (or immediately after the same-day AGM) in the company’s conference room at 1399 Chuangxinyi Road, Songbei District, Harbin, Heilongjiang Province, PRC.

The class meeting will ask holders of H shares to vote on two special resolutions:

1. Repurchase Mandate • Authorises the Board to buy back, in a single tranche or multiple tranches, up to 10% of the company’s total issued H shares as of the meeting date. • Repurchases must be executed through the Hong Kong Stock Exchange. • The mandate remains valid for 12 months from the date of approval, until the first AGM thereafter, or until earlier revocation/amendment by shareholders, whichever occurs first.

2. Articles of Association Amendment • Conditional on the buyback mandate being approved and executed, the Board will be empowered to revise Articles 16, 17, and related provisions to reflect changes in total issued shares, share-capital structure and registered capital stemming from any H-share repurchase.

Proxy arrangements require completed forms—together with notarised powers of attorney, where applicable—to reach the Hong Kong share registrar, Computershare Hong Kong Investor Services Limited, at least 24 hours before the scheduled meeting.

Completion or return of a proxy form does not preclude shareholders from attending and voting in person; in such cases, any previously submitted proxy will be deemed revoked.
