JA Solar Holdings Co., Ltd.(Nasdaq:JASO), ("JA Solar" or "the Company"), one of the world's largest manufacturers of high-performance solar cells and solar power products, announced that it will change the ratio of its American Depositary Shares ("ADSs") to ordinary shares from one (1) ADS representing one (1) ordinary share to one ADS representing five (5) ordinary shares, effective on December 10, 2012.

Each shareholder of record at the close of business on December 10, 2012 will be required to exchange every five ADSs then held for one new ADS. The effect on the ADS price will take place on December 10, 2012.

ADS holders will be required to surrender their existing ADSs in exchange for new ADSs of the Company. The Company's Depositary, The Bank of New York Mellon, will provide further details on or prior to November 26, 2012 to NASDAQ and other market participants.
