Capital structure impact Despite completing over 206 million share buybacks across both listings, Sinopec’s issued share count is unchanged as of 08 September 2026 because the repurchased shares have not yet been cancelled. Once the cancellations are processed, the total share capital will decline by approximately 0.17 %.

No other corporate actions—such as new share issues, conversions, or resale of treasury shares—were disclosed in the filing.
