(Reuters) -Advance Auto Parts said on Thursday private equity firm Carlyle Group would buy its Worldpac unit for $1.5 billion in cash, sending its shares about 11% higher in premarket trade.

Worldpac, a wholesale parts distribution business, generated about $2.1 billion in revenue for the year ended June 30.

The deal is expected to close before the end of the year.
