Date of closure of Register of Members in relation to the distribution of Final Dividend to holders of the Company’s H shares

The Board has proposed to distribute a dividend for the year of 2021 of RMB0.1 per share (tax inclusive) (the “Final Dividend”) based on the total number of shares of the Company on the record date for dividend distribution. Subject to the passing of the resolution by the Shareholders of the Company at the AGM, the Final Dividend is expected to be distributed on or around Thursday, 28 July 2022 to H shares Shareholders whose names appear on the Register of Members of the Company’s H shares at the close of business on Tuesday, 5 July 2022. The Final Dividend is denominated and declared in Renminbi. The Final Dividend payable to the holders of the Company’s A shares shall be paid in Renminbi while those payable to the holders of the Company’s H shares shall be paid in Hong Kong dollars. The amount of Hong Kong dollars payable shall be calculated on the basis of the average closing exchange rates for Hong Kong dollars as announced by the Foreign Exchange Trading Centre of the PRC one calendar week prior to the approval of the Final Dividend at the AGM.

The Register of Members of the Company’s H shares will be closed from Thursday, 30 June 2022 to Tuesday, 5 July 2022 (both days inclusive), during which period no transfer of H shares will be registered in order to confirm the H shares Shareholders’ entitlement to receive the Final Dividend. Unregistered holders of the Company’s H shares who wish to receive the Final Dividend should lodge the H shares transfer documents and the relevant share certificates with the Company’s H shares share registrar, Hong Kong Registrars Limited, at Shops 1712-1716, 17/F, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong not later than 4:30 p.m. on Wednesday, 29 June 2022.

For domestic individuals and corporate investors who invested in H shares of the Company via Southbound Trading, the Company has entered into “The Agreement on Distribution of Cash Dividends of H shares for Southbound Trading” with CSDC Shanghai Branch, pursuant to which, the CSDC Shanghai Branch, as the nominee holder of H shares of the Company for the investors of Southbound Trading, will receive cash dividend distributed by the Company and distribute the cash dividend to the relevant investors of Southbound Trading through its depository and clearing system. The arrangement of the record date of the investors of Southbound Trading is consistent with that of the Company’s H shares shareholders. The Final Dividend is expected to be paid within three business days of Southbound Trading from Thursday, 28 July 2022. The Final Dividend payable to the investors of Southbound Trading who invested in H shares of the Company will be paid in Renminbi.

Withholding of both corporate and individual income tax on dividends:

Pursuant to the Law of the People’s Republic of China on Enterprise Income Tax, and its implementation rules and the relevant provisions, when the Company distributes dividends to its Shareholders who are overseas non-resident enterprises on the Register of Members of H shares of the Company, the Company has the obligation to withhold the enterprise income tax at a rate of 10%. All shares registered in the name of non-individual shareholders on the Register of Members of H shares of the Company, including HKSCC (Nominees) Limited, other corporate nominees and trustees, or other groups and organizations will be treated as shares held by non-resident enterprise shareholders and, thus, the income tax will be withheld on the dividends received. If any holder of the Company’s H shares would like to change his/ her/its residency status, please enquire the relevant procedures with his/her/its nominee or trustee.

Pursuant to the Guo Shui Han [2011] No. 348 issued by the State Administration of Taxation, for individual holders of the Company’s H shares (the “Individual H Shares Shareholders”), the Company shall withhold and pay the individual income tax for dividends on behalf of such Shareholders. Meanwhile, the Individual H Shares Shareholders may be entitled to relevant tax preferential treatments under the tax agreements between the PRC and the countries in which the Individual H Shares Shareholders reside or under the tax arrangements between Mainland China and Hong Kong (Macau). For Individual H Shares Shareholders who are Hong Kong or Macau residents or who reside in a country which has entered into an agreement with the PRC stipulating a tax rate of lower than 10% in respect of dividend, the Company will withhold and pay individual income tax at the rate of 10% on behalf of such Individual H Shares Shareholders. For Individual H Shares Shareholders who reside in a country which has entered into an agreement with the PRC stipulating a tax rate of lower than 10% in respect of dividend, the Company may make applications on their behalf to seek entitlement of the relevant agreed preferential treatments pursuant to the Announcement of the State Administration of Taxation in relation to Issuance of the “Administrative Measures on Preferential Treatment Entitled by Non-residents Under Tax Treaties” (《國家稅務總局關於發佈〈非居民納稅人享受稅收協定待遇管理辦法〉的公告》 ). For Individual H Shares Shareholders who reside in a country which has entered into an agreement with the PRC stipulating a tax rate of higher than 10% but lower than 20% in respect of dividend, the Company will withhold and pay individual income tax at the actual agreed tax rate on behalf of such Individual H Shares Shareholders. For Individual H Shares Shareholders who reside in a country which has not entered into any tax agreement with the PRC or which has entered into a tax agreement with the PRC stipulating a tax rate of 20% in respect of dividend, or under any other circumstances, the Company will withhold and pay the individual income tax at a tax rate of 20% on behalf of such Individual H Shares Shareholders.

Pursuant to the Notice on Taxation Policies concerning the Pilot Program of an Interconnection Mechanism for Transactions in the Shanghai and Hong Kong Stock Markets (Cai Shui [2014] No. 81):

For dividends received by the Mainland China investors who invest in H shares of the Company via the Shanghai-Hong Kong Stock Connect, the Company will withhold and pay income tax at the rate of 20% on behalf of such individuals and investment funds. The Company will neither withhold nor pay income tax of the dividends received by corporate investors, and the tax should be declared and paid by the corporate investors themselves.

For dividends received by Hong Kong investors (enterprises or individuals) that invest in A shares of the Company via the Shanghai-Hong Kong Stock Connect, income tax shall be withheld at the tax rate of 10% by the Company and the Company shall undergo the procedure of tax withholding and declaration with the tax authorities in charge. For investors who reside in a country which has entered into a tax agreement with the PRC stipulating a tax rate of less than 10% in respect of dividend, the enterprises or individuals may apply to the taxation authority of the Company for tax preference of the tax agreement by themselves or authorize the tax withholding obligator to file such an application. The taxation authority in charge will, after verification and approval, refund the taxes based on the difference between the taxes levied and the taxes payable calculated according to the tax rate of the tax agreement.

6

The Company will determine the country of residence of the Individual H Shares Shareholders based on the registered address as recorded in the Register of Members of the Company’s H shares (the “Registered Address”) as at the close of business on Tuesday, 5 July 2022 and will withhold and pay individual income tax on that basis. If the country of residence of the Individual H Shares Shareholder is not the same as the Registered Address, the Individual H Shares Shareholder shall notify the Company’s H shares share registrar, Hong Kong Registrars Limited, at Shops 1712-1716, 17/F, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong, and provide relevant supporting documents not later than 4:30 p.m. on Wednesday, 29 June 2022. If the Individual H Shares Shareholders do not provide relevant supporting documents to the Company’s H shares share registrar within the time limit stated above, the Company will determine the country of residence of the Individual H Shares Shareholders based on the Registered Address recorded in the Register of Members of the Company’s H shares as at the close of business on Tuesday, 5 July 2022.

The Company will assume no liability and will not entertain any claims arising from and whatsoever in respect of any delay or error in determination of the residency status of the individual H Shares Shareholders of the Company or any disputes over the tax withholding mechanism.

The record date, distribution procedures and time for the distribution of dividends applicable to holders of the Company’s A shares will be announced in a separate announcement.

The PRC Company Law (to which the Company is subject and has incorporated in its Articles of Association) provides that a joint stock limited company incorporated in the PRC may not repurchase its shares unless such repurchase is effected for the purpose of a) reducing its registered share capital; (b) merging with other companies which hold shares of the Company; (c) granting shares as reward to the staff of the Company; (d) acquiring the shares of shareholders who vote against any shareholders’ resolution on a merger or division; (e) utilizing the shares for conversion of corporate bonds issued by the Company which are convertible into shares; or (f) where it is necessary for safeguarding the Company’s value and shareholders’ equity.

PRC laws and regulations and the Shanghai Listing Rules permit shareholders of a PRC joint stock limited company to grant a general mandate to the directors to repurchase the A shares of such company that are listed on the Shanghai Stock Exchange. Such mandate is required to be given by way of a special resolution passed by shareholders in general meeting and special resolutions passed by holders of domestic shares and overseas listed foreign shares in separate class meetings.

The Company would like to draw the Shareholders’ attention to the fact that, even if the A Share Repurchase Mandate is approved at the AGM, the A Shareholders Class Meeting and H Shareholders Class Meeting, in the case of repurchase of A shares to be canceled to reduce the registered capital, the Company will still be required, under applicable PRC laws and regulations and the Shanghai Listing Rules, to seek additional, specific and prior approval from its Shareholders in general meeting by way of special resolution(s) for each repurchase of A Shares and to provide further information and details of such repurchase of A Shares in accordance with the requirements under applicable PRC laws and regulations and the Shanghai Listing Rules.

PRC laws and regulations and the Hong Kong Listing Rules permit shareholders of a PRC joint stock limited company to grant a general mandate to the directors to repurchase H shares of such company that are listed on the Hong Kong Stock Exchange. Such mandate is required to be given by way of a special resolution passed by shareholders in general meeting and special resolutions passed by holders of domestic shares and overseas listed foreign shares in separate class meetings.

Date of closure of Register of Members in relation to the distribution of Final Dividend to holders of the Company’s H shares

The Board has proposed to distribute a dividend for the year of 2021 of RMB0.1 per share (tax inclusive) (the “Final Dividend”) based on the total number of shares of the Company on the record date for dividend distribution. Subject to the passing of the resolution by the Shareholders of the Company at the AGM, the Final Dividend is expected to be distributed on or around Thursday, 28 July 2022 to H shares Shareholders whose names appear on the Register of Members of the Company’s H shares at the close of business on Tuesday, 5 July 2022. The Final Dividend is denominated and declared in Renminbi. The Final Dividend payable to the holders of the Company’s A shares shall be paid in Renminbi while those payable to the holders of the Company’s H shares shall be paid in Hong Kong dollars. The amount of Hong Kong dollars payable shall be calculated on the basis of the average closing exchange rates for Hong Kong dollars as announced by the Foreign Exchange Trading Centre of the PRC one calendar week prior to the approval of the Final Dividend at the AGM.

The Register of Members of the Company’s H shares will be closed from Thursday, 30 June 2022 to Tuesday, 5 July 2022 (both days inclusive), during which period no transfer of H shares will be registered in order to confirm the H shares Shareholders’ entitlement to receive the Final Dividend. Unregistered holders of the Company’s H shares who wish to receive the Final Dividend should lodge the H shares transfer documents and the relevant share certificates with the Company’s H shares share registrar, Hong Kong Registrars Limited, at Shops 1712-1716, 17/F, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong not later than 4:30 p.m. on Wednesday, 29 June 2022.

For domestic individuals and corporate investors who invested in H shares of the Company via Southbound Trading, the Company has entered into “The Agreement on Distribution of Cash Dividends of H shares for Southbound Trading” with CSDC Shanghai Branch, pursuant to which, the CSDC Shanghai Branch, as the nominee holder of H shares of the Company for the investors of Southbound Trading, will receive cash dividend distributed by the Company and distribute the cash dividend to the relevant investors of Southbound Trading through its depository and clearing system. The arrangement of the record date of the investors of Southbound Trading is consistent with that of the Company’s H shares shareholders. The Final Dividend is expected to be paid within three business days of Southbound Trading from Thursday, 28 July 2022. The Final Dividend payable to the investors of Southbound Trading who invested in H shares of the Company will be paid in Renminbi.

Withholding of both corporate and individual income tax on dividends:

Pursuant to the Law of the People’s Republic of China on Enterprise Income Tax, and its implementation rules and the relevant provisions, when the Company distributes dividends to its Shareholders who are overseas non-resident enterprises on the Register of Members of H shares of the Company, the Company has the obligation to withhold the enterprise income tax at a rate of 10%. All shares registered in the name of non-individual shareholders on the Register of Members of H shares of the Company, including HKSCC (Nominees) Limited, other corporate nominees and trustees, or other groups and organizations will be treated as shares held by non-resident enterprise shareholders and, thus, the income tax will be withheld on the dividends received. If any holder of the Company’s H shares would like to change his/ her/its residency status, please enquire the relevant procedures with his/her/its nominee or trustee.

12

Pursuant to the Guo Shui Han [2011] No. 348 issued by the State Administration of Taxation, for individual holders of the Company’s H shares (the “Individual H Shares Shareholders”), the Company shall withhold and pay the individual income tax for dividends on behalf of such Shareholders. Meanwhile, the Individual H Shares Shareholders may be entitled to relevant tax preferential treatments under the tax agreements between the PRC and the countries in which the Individual H Shares Shareholders reside or under the tax arrangements between Mainland China and Hong Kong (Macau). For Individual H Shares Shareholders who are Hong Kong or Macau residents or who reside in a country which has entered into an agreement with the PRC stipulating a tax rate of lower than 10% in respect of dividend, the Company will withhold and pay individual income tax at the rate of 10% on behalf of such Individual H Shares Shareholders. For Individual H Shares Shareholders who reside in a country which has entered into an agreement with the PRC stipulating a tax rate of lower than 10% in respect of dividend, the Company may make applications on their behalf to seek entitlement of the relevant agreed preferential treatments pursuant to the Announcement of the State Administration of Taxation in relation to Issuance of the “Administrative Measures on Preferential Treatment Entitled by Non-residents Under Tax Treaties” (《國家稅務總局關於發佈〈非居民納稅人享受稅收協定待遇管理辦法〉的公告》 ). For Individual H Shares Shareholders who reside in a country which has entered into an agreement with the PRC stipulating a tax rate of higher than 10% but lower than 20% in respect of dividend, the Company will withhold and pay individual income tax at the actual agreed tax rate on behalf of such Individual H Shares Shareholders. For Individual H Shares Shareholders who reside in a country which has not entered into any tax agreement with the PRC or which has entered into a tax agreement with the PRC stipulating a tax rate of 20% in respect of dividend, or under any other circumstances, the Company will withhold and pay the individual income tax at a tax rate of 20% on behalf of such Individual H Shares Shareholders.

Pursuant to the Notice on Taxation Policies concerning the Pilot Program of an Interconnection Mechanism for Transactions in the Shanghai and Hong Kong Stock Markets (Cai Shui [2014] No. 81):

For dividends received by the Mainland China investors who invest in H shares of the Company via the Shanghai-Hong Kong Stock Connect, the Company will withhold and pay income tax at the rate of 20% on behalf of such individuals and investment funds. The Company will neither withhold nor pay income tax of the dividends received by corporate investors, and the tax should be declared and paid by the corporate investors themselves.

For dividends received by Hong Kong investors (enterprises or individuals) that invest in A shares of the Company via the Shanghai-Hong Kong Stock Connect, income tax shall be withheld at the tax rate of 10% by the Company and the Company shall undergo the procedure of tax withholding and declaration with the tax authorities in charge. For investors who reside in a country which has entered into a tax agreement with the PRC stipulating a tax rate of less than 10% in respect of dividend, the enterprises or individuals may apply to the taxation authority of the Company for tax preference of the tax agreement by themselves or authorize the tax withholding obligator to file such an application. The taxation authority in charge will, after verification and approval, refund the taxes based on the difference between the taxes levied and the taxes payable calculated according to the tax rate of the tax agreement.

13

The Company will determine the country of residence of the Individual H Shares Shareholders based on the registered address as recorded in the Register of Members of the Company’s H shares (the “Registered Address”) as at the close of business on Tuesday, 5 July 2022 and will withhold and pay individual income tax on that basis. If the country of residence of the Individual H Shares Shareholder is not the same as the Registered Address, the Individual H Shares Shareholder shall notify the Company’s H shares share registrar, Hong Kong Registrars Limited, at Shops 1712-1716, 17/F, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong, and provide relevant supporting documents not later than 4:30 p.m. on Wednesday, 29 June 2022. If the Individual H Shares Shareholders do not provide relevant supporting documents to the Company’s H shares share registrar within the time limit stated above, the Company will determine the country of residence of the Individual H Shares Shareholders based on the Registered Address recorded in the Register of Members of the Company’s H shares as at the close of business on Tuesday, 5 July 2022.

The Company will assume no liability and will not entertain any claims arising from and whatsoever in respect of any delay or error in determination of the residency status of the individual H Shares Shareholders of the Company or any disputes over the tax withholding mechanism.

If holders of the Company’s H shares have any questions regarding the aforesaid arrangements, please consult your tax advisor on the taxation impact in Mainland China, Hong Kong and other countries (regions) for owning and disposing the Company’s H shares.

The record date, distribution procedures and time for the distribution of dividends applicable to holders of the Company’s A shares will be announced in a separate announcement.

In accordance with the Hong Kong Listing Rules, this appendix serves as the explanatory letter to provide you with requisite information reasonably necessary to enable you to make an informed decision on whether to vote for or against the special resolution(s) to be proposed at the AGM, the A Shareholders Class Meeting and the H Shareholders Class Meeting for the grant of the H Share Repurchase Mandate to the Directors.

H Share Repurchase Mandate

Reasons for Repurchasing H Shares

The Directors believe that the flexibility afforded by the H Share Repurchase Mandate would be beneficial to and in the best interest of the Company and its Shareholders. Such repurchases may, depending on market conditions and funding arrangements at such time, lead to an enhancement of the net asset value per share and/or earnings per share of the Company. Such repurchases will only be made when the Directors believe that such repurchases will benefit the Company and its Shareholders.

Registered Capital

As at the Latest Practicable Date, the registered capital of the Company was RMB10,823,813,500 comprising 3,495,000,000 H Shares of RMB1.00 each and 7,328,813,500 A Shares of RMB1.00 each.

Exercise of the H Share Repurchase Mandate

Subject to the passing of the relevant special resolution(s) set out in the notice of the AGM, the special resolution(s) approving the grant to the Board of the H Share Repurchase Mandate at the A Shareholders Class Meeting and H Shareholders Class Meeting respectively, the Board will be granted the H Share Repurchase Mandate until the earlier of a) the conclusion of the annual general meeting of the Company for 2022; b) the expiration date of 12 months after the resolution is adopted by the AGM; c) the date on which the authority conferred by this resolution is revoked or varied by a special resolution of shareholders at a general meeting, or a special resolution of shareholders at a class meeting of domestic share (A share) shareholders or a class meeting of overseas-listed foreign invested share (H share) shareholders (the “Relevant Period”). The exercise of the H Share Repurchase Mandate is subject to relevant approval(s) of and/or filings with State Administration of Foreign Exchange and/or any other regulatory authorities as required by the laws, rules and regulations of the PRC being obtained and/or carried out.

The exercise in full of the H Share Repurchase Mandate (on the basis of 3,495,000,000 H Shares in issue as at the Latest Practicable Date and there is no change to the number of issued H Shares prior to the date of the AGM, the A Shareholders Class Meeting and H Shareholders Class Meeting) would result in a maximum of 349,500,000 H Shares being repurchased by the Company during the Relevant Period, being the maximum of 10% of the total H Shares in issue as at the date of passing the relevant resolution(s).

Funding of Repurchases

In repurchasing its H Shares, the Company intends to apply funds from the Company’s internal resources (which may include surplus funds and retained profits) legally available for such purpose in accordance with the Company’s Articles of Association and the applicable laws, rules and regulations of the PRC.

18

The Company is empowered by the Company’s Articles of Association to repurchase its H Shares. Any repurchases by the Company may only be made out of either the funds of the Company that would otherwise be available for dividend or distribution or out of the proceeds of a new issue of shares made for such purpose. The Company’s registered capital will be reduced by an amount equivalent to the aggregate nominal value of the H Shares so cancelled. The Company may not repurchase securities on the Hong Kong Stock Exchange for a consideration other than cash or for settlement otherwise than in accordance with the trading rules of the Hong Kong Stock Exchange from time to time.

General Information

The Directors consider that there would not be a material adverse impact on the working capital and on the gearing position of the Company in the event that the H Share Repurchase Mandate is to be exercised in full at any time during the proposed repurchase period (as compared with the position disclosed in the latest published audited accounts contained in the annual report of the Company for the year ended 31 December 2021). However, the Directors do not propose to exercise the H Share Repurchase Mandate to such extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company or the gearing levels of the Company. The number of H Shares to be repurchased on any occasion, the price and other terms upon which the same are bought back will be decided by the Directors at the relevant time having regarded to the circumstances then prevailing, in the best interests of the Company.

The Directors have undertaken to the Hong Kong Stock Exchange that, so far as the same may be applicable, they will exercise the powers of the Company to make repurchases under the H Share Repurchase Mandate in accordance with the Hong Kong Listing Rules, the Company’s Articles of Association and the applicable laws, rules and regulations of the PRC.

H Shares Prices

The highest and lowest prices at which the H Shares have been traded on the Hong Kong Stock Exchange during each of the twelve months preceding the Latest Practicable Date were as follows:

19

H Shares repurchased by the Company

No repurchase of H Shares has been made by the Company in the previous six months preceding the Latest Practicable Date (whether on the Hong Kong Stock Exchange or otherwise).

Disclosure of Interests

If as a result of a share repurchase by the Company, a substantial shareholder’s proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition for the purpose of the Takeovers Code. Accordingly, a shareholder, or group of shareholders acting in concert, could obtain or consolidate control of the Company or become obligated to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

The Directors are not aware of any consequences which will arise under the Takeovers Code and/or any similar applicable law, as a result of any repurchases to be made under the H Share Repurchase Mandate. Moreover, the Directors will not make share repurchase on the Hong Kong Stock Exchange if such repurchase would result in the requirements under Rule 8.08 of the Hong Kong Listing Rules not being complied with.

None of the Directors nor, to the best of their knowledge, having made all reasonable enquiries, any of their close associates presently intends to sell H Shares to the Company under the H Share Repurchase Mandate in the event that the H Share Repurchase Mandate is approved by the Shareholders and the conditions (if any) to which the H Share Repurchase Mandate is subject are fulfilled.

The Company has not been notified by any core connected persons (as defined in the Hong Kong Listing Rules) of the Company that they have a present intention to sell any H Shares to the Company, or that they have undertaken not to sell any H Shares held by them to the Company in the event that the H Share Repurchase Mandate is approved by its Shareholders and the conditions (if any) to which the H Share Repurchase Mandate is subject are fulfilled.
