Both the English and Chinese versions of future documents will be accessible on the company website (www.spc.com.cn) and the HKEXnews platform (www.hkexnews.hk). Printed copies will no longer be dispatched except in two circumstances:

1. Actionable Documents If a functional email address is not supplied to the shareholder’s bank, broker, custodian, nominee or HKSCC Nominees Limited, the company will send actionable corporate communications in hard copy until an email address is recorded.

2. Explicit Hard-Copy Request Shareholders preferring printed materials may submit the reply form to Computershare Hong Kong Investor Services Limited (17M Floor, Hopewell Centre, 183 Queen’s Road East, Wan Chai, Hong Kong) or email spc.ecom@computershare.com.hk, stating their name, address and the request for hard copies.
