PRICING OF THE TRANSFER

According to valuation report, the total assets, total liabilities and total value of shareholders equity of the Target Company amounted to RMB1,390.7725 million, RMB9.5989 million and RMB1,381.1736 million respectively as at the base date. With agreement upon discussion, the transferee shall pay the transferor for the Target Interests in a total price of RMB780.7774 million.

PURPOSE OF THE TRANSFER AND THE EFFECT ON THE COMPANY

In 2016, Taishan Power had a total profit of RMB1,278.4385 million (on a consolidated basis), of which approximately RMB1,217 million was an one-off non-recurring gain derived from the sale of the equity interest of its controlling subsidiary. Since Taishan Power has no investment projects that are in line with development strategy of the Company in the next few years and in order to increase the efficiency in use of capital, Shandong Company proposes to recoup its investment by transferring its equity interest in Taishan Power. The Transfer is conducive to the Company by focusing on developing high quality resource business, which is consistent with development strategy of the Company.

HETHC and its shareholder, Huaneng Group, have maintained healthy business development and stable financial position for the last three years. The Board of Directors of the Company is of the view that HETHC is competent to perform the contract and pay the consideration.

Following completion of the Transfer, Taishan Power will not be consolidated into the accounts of the Company. The Transfer will not impose any material impact on the financial position of the Company and will not prejudice the interest of the Company and its shareholders.

IMPLICATIONS UNDER THE HONG KONG LISTING RULES

According to relevant percentage ratios as defined pursuant to Rule 14.07 of the Hong Kong Listing Rules, the Transfer constitutes a discloseable transaction under Chapter 14 of the Hong Kong Listing Rules. The Transfer also constitutes a connected transaction under Chapter 14A of the Hong Kong Listing Rules. As the scale of the Transfer exceeds 0.1% but does not exceed 5% of the applicable percentage ratios as calculated pursuant to Rule 14.07 of the Hong Kong Listing Rules, therefore, the Company is only required to comply with the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but is exempt from independent shareholders’ approval requirements.

The Board of Directors of the Company has considered and approved the resolution regarding the Transfer. Messrs. Cao Peixi, Guo Junming, Liu Guoyue, Fan Xiaxia and Wang Yongxiang, all being Directors of the Company having related relationship, abstained from voting on the board resolution relating to the Transfer. The resolution was voted by Directors who are not unrelated to the Transfer. The Directors (including independent non-executive Directors) are of the view that, Transfer Agreement was entered into: (i) on normal commercial terms (on arm’s length basis or on terms no



less favourable to the Company than terms available from independent third parties); (ii) on terms that are fair and reasonable and are in the interests of the Company and its shareholders as a whole and (iii) in the ordinary and usual course of business of the Company.
