Shares of ATM-maker NCR  (NCR) - Get Report slid on Wednesday following a report that said the company was having trouble attracting a bidder after two private-equity firms said no to making an offer.

Citing sources familiar with the situation, The New York Post reported on Wednesday that two private-equity firms who expressed interest in making an offer for the cash-machine maker -- Warburg Pincus and Apollo Global Management -- have both walked away, and that no new bidders have stepped up.

The Atlanta-based company, which also makes barcode scanners and self-checkout kiosks, put itself up for sale in early May. Media reports about interest from Warburg Pincus and Apollo at the time sent the company's stock to over $30 a share.

Shares of NCR were down 2.17% at $30.66 in early afternoon trading on the New York Stock Exchange.
