Dear shareholders,

First at all, on behalf of the Board of Directors of China Unicom, I would like to express my sincere gratitude to all shareholders and the different parts of the society for their support. In the first half of 2014, with a changing market environment and a slowing-down industry, the Company steadily implemented the strategy of “Leading Mobile Broadband and Innovating Operational Integration”. As a result, the Company continued to expand its market share in service revenue, further optimised its business structure, and constantly improved its profitability.

Due to the replacement of business tax with value-added tax as well as the changes in market environment, the Company’s revenue growth slowed down. Nevertheless, its service revenue growth still outperformed the industry average by 3.4 percentage points. The Company’s business structure was further optimised, with mobile business and non-voice business accounting for 64.1% and 59.5% of total service revenue, respectively.

With the continuous revenue growth and improvement in business structure, the Company achieved steady improvement in profitability. The Company’s EBITDA increased by 13.1% year-on-year to RMB47.69 billion, and its net profit increased by 25.8% year-on-year to RMB6.69 billion. The Company’s overall financial status turned more solid, with its operating cash flow up by 1.1% year-on-year and its free cash flow reaching RMB20.15 billion, laying a more solid foundation for its sustainable growth in the future.

Among the dividend payable of approximately RMB773 million was due to Unicom BVI as at 30 June 2014.

Pursuant to the PRC enterprise income tax law, a 10% withholding income tax is levied on dividends declared on or after 1 January 2008 by foreign investment enterprises to their foreign enterprise shareholders unless the enterprise investor is deemed as a PRC Tax Resident Enterprise (“TRE”). On 11 November 2010, the Company obtained an approval from Tax Bureau, pursuant to which the Company qualifies as a PRC TRE from 1 January 2008. Therefore, as at 30 June 2014, the Company’s subsidiaries in the PRC did not accrue for withholding tax on dividends distributed to the Company and there has been no deferred tax liability accrued in the Group’s unaudited condensed consolidated interim financial information for the undistributed profits of the Company’s subsidiaries in the PRC.

For the Company’s non-PRC TRE shareholders, the Company would distribute dividends after deducting the amount of enterprise income tax payable by these non-PRC TRE shareholders thereon and reclassify the related dividend payable to withholding tax payable upon the declaration of such dividends. The requirement to withhold tax does not apply to the Company’s shareholders appearing as individuals in its share register.
