CDK Global Authorized to Purchase an Initial Ten Million Shares of Its Common Stock

HOFFMAN ESTATES, Ill., Jan. 21, 2015 (GLOBE NEWSWIRE) -- The Board of Directors of CDK Global, Inc. (Nasdaq:CDK) has authorized the purchase of ten million shares of its common stock.

"We are pleased to announce a ten million share repurchase authorization. We continue to evaluate how to best deploy our free cash flow to generate long term shareholder value and this is a prudent next step in our plan. We have excess cash on our balance sheet and intend to utilize this authorization to offset dilution from employee equity compensation plans and return capital to our shareholders," said Steve Anenen, President and Chief Executive Officer, CDK Global. "We are confident that we will generate increasing levels of free cash flow which will enable us to invest while also returning capital through our announced dividend and share buyback authorization," Anenen concluded.

Under the authorization for the stock repurchase program, CDK may purchase its common stock in the open market or in privately negotiated transactions. The actual timing, number and price of any shares to be repurchased will be determined at management's discretion and will depend on a number of factors, which may include the market price of the shares, general market and economic conditions, and other potential uses for free cash flow. This authorization is effective immediately and will expire on January 19, 2018.
