Q1 2015Company Presentation

1

Safe Harbor Statement and DisclosureStatements in this presentation regarding 51job’s future business, operating results and financial condition constitute "forward-looking" statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and as defined in the Private Securities Litigation Reform Act of 1995. These statements are based upon management’s current views and expectations and actual results could differ materially. Among the factors that could cause the Company’s actual results to differ are, but not limited to, market acceptance of its services; its ability to expand into other recruitment and human resource services; its ability to control operating costs and expenses; its potential need for additional capital and the availability of such capital; changes in its management team and other key personnel; behavioral and operational changes of customers in meeting their human resource needs as they respond to evolving social, economic, regulatory and political changes in China as well as stock market volatilities; introduction by its competitors of new or enhanced products or services; price competition in the market for the various human resource services that the Company provides in China; fluctuations in the value of the Renminbi against the U.S. dollar and other currencies; acceptance of new products and services developed or introduced by the Company outside of the human resources industry; any risks related to acquisitions or investments the Company has made or will make in the future; and fluctuations in general economic conditions. For additional information on these and other potential factors that could affect the Company’s financial results, please refer to the Company’s filings with the Securities and Exchange Commission. 51job undertakes no obligation to publicly update any forward-looking statements whether as a result of new information, future events or otherwise.

To supplement the consolidated financial statements presented in accordance with US GAAP, the Company uses non-GAAP financial measures to exclude share-based compensation expense, gain/loss from foreign currency translation, convertible senior notes issuance costs, change in fair value of convertible notes and change in fair value of zero-strike call options, as well as the related tax effect of these items. The Company believes excluding these items from its non-GAAP financial measures is useful forits management and investors to assess and analyze the Company’s core operating results as these expenses are not directly attributable to the underlying performance of the Company’s business operations and may not impact its cash earnings. The Company also believes that excluding these expenses are important in helping investors to understand the Company’s current financial performance and future prospects and to compare business trends among different reporting periods on a consistent basis. The presentation of these additional measures should not be considered a substitute for or superior to GAAP results or asbeing comparable to results reported or forecasted by other companies.

The facts and statistics used in this presentation relating to the human resource services industry and economy in China are derived from various government and institute research publications. While 51job has taken reasonable care to ensure that these facts and statistics presented are accurately reproduced from such sources, 51job has not independently verified them.
