According to a recent announcement, Sinopec Oilfield Service Corporation (stock code: 1033) plans to reduce its registered capital and abolish its supervisory committee. A resolution on amendments to the company’s Articles of Association and related appendices was approved at the tenth meeting of the eleventh session of its board of directors on 28 October 2025.

The decision reflects updates to the Company Law of the People’s Republic of China (2023 Revision) and related regulatory requirements from the China Securities Regulatory Commission. The supervisory committee’s duties will be assumed by the company’s audit committee. The proposed amendments also include adjustments to the board structure, revised notice periods for general meetings, additional voting options during resolutions, and measures to strengthen shareholder rights.

Additionally, Sinopec Oilfield Service Corporation intends to adjust its registered capital to align with the cancellation of certain H shares and A shares. The total number of issued shares decreased to 18,957,045,833 from previous cancellations, prompting a corresponding capital reduction.

These resolutions on capital reduction, supervisory committee abolition, and amendments to the Articles of Association are subject to shareholder approval at a forthcoming general meeting. A circular detailing the proposed amendments and the meeting notice will be provided to shareholders in due course.
