Key points 1. Shareholder options • Option 1 – Website Version: Access all corporate communications via www.sinopec.com.hk with email or letter notifications. • Option 2 – Printed English version only. • Option 3 – Printed Chinese version only. • Option 4 – Both printed English and Chinese versions.
