Reference is made to the announcement dated 20 April 2021 jointly issued by Inner Mongolia Energy Engineering (Group) Co., Ltd.* (內蒙古能源建設投資（集團）有限公司) ("IMG") and

Inner Mongolia Energy Engineering Co., Ltd. ("IME") (the "Joint Announcement") in relation to the voluntary conditional cash offer by Cinda International Capital Limited on behalf of IMG to acquire all the issued H Shares in IME, the proposed privatisation and voluntary withdrawal of listing of the H Shares in IME, and the proposed merger by absorption of IME by IMG. Unless otherwise defined, capitalised terms used herein shall have the same meanings as those defined in the Joint Announcement.

DELAY IN DESPATCH OF THE COMPOSITE DOCUMENT

Pursuant to Rule 8.2 of the Takeovers Code, the Composite Document is required to be despatched to the IME H Shareholders within 21 days from the date of the Joint Announcement, (i.e. on or before 11 May 2021), unless consent is obtained from the Executive to extend the deadline for the despatch of the Composite Document.

As additional time is required to finalise the information to be disclosed in the Composite Document, which includes but is not limited to the financial information of the IME Group due to the absence of an auditor, an application has been made to the Executive for consent to extend the deadline for the despatch of the Composite Document to a date falling on or before 31 May 2021, and the Executive has indicated that it is minded to grant such consent.

Further announcement(s) will be jointly made by IMG and IME when the Composite Document is despatched.

WARNING

The H Share Offer is conditional upon the satisfaction or (where applicable) waiver of the Conditions and the Merger is conditional upon the satisfaction or (where applicable) waiver of the Merger Conditions as described in the Joint Announcement in all aspects. Accordingly, the H Share Offer may or may not become unconditional and the issue of this joint announcement does not imply that the H Share Offer or the Delisting will be completed. As the Merger Conditions (in respect of the Merger) are different from the Conditions (in respect of the H Share Offer), the IME Shareholders and potential investors of IME should be aware that even following the successful completion of the H Share Offer and the Delisting, there is no certainty that the Merger will proceed. The IME Shareholders and/or potential investors of IME should therefore exercise caution when dealing in the securities of IME. Persons who are in doubt as to the action they should take should consult their licensed securities dealers or registered institutions in securities, bank managers, solicitors, professional accountants or other professional advisers.
