ANNOUNCEMENT

INSIDE INFORMATION

This announcement is made by China Energy Engineering Corporation Limited (the "Company", together with its subsidiaries, the "Group") pursuant to Rule 13.09 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited and the provisions for inside information under Part XIVA of the Securities and Futures Ordinance (Chapter 571 of the Laws of Hong Kong).

The board of directors of the Company (the "Board") wishes to inform the shareholders of the Company and potential investors that, based on a preliminary assessment, it is expected to record the unaudited net profit attributable to the equity holders of the Company for the six months ended 30 June 2020 in the range of approximately RMB750 million to RMB1,300 million, representing a decrease in the net profit attributable to the equity holders of the Company as compared to the corresponding period ended 30 June 2019. This was mainly due to the fact that some enterprises of the Company are located in regions mostly exposed to the COVID-19 pandemic, and relevant businesses of the Company were affected by pandemic control and prevention measures, causing projects to delay in progress, which in turn resulted in a loss in the unaudited net profit attributable to the equity holders of the Company in the first quarter of 2020.

As at the date of this announcement, the Company is still in the process of preparing the interim results for the six months ended 30 June 2020. The information contained in this announcement is only based on the preliminary assessment made with reference to the unaudited consolidated management accounts for the six months ended 30 June 2020 and the information currently available, and is not based on any figures or information that have been audited or reviewed by the Company's auditors or the audit committee of the Board. Shareholders and potential investors are advised to refer to details in the interim results announcement of the Company for the six months ended 30 June 2020, which is expected to be published by the end of August 2020.
