Cardtronics, the largest non-bank owner of automated teller machines (ATMs) filed to go public on Wednesday. Cardtronics operates 12,000 ATMs throughout the United States at which nearly 65 million transactions were processed in 2003. In fiscal 2003, the firm generated $110 million in total revenue and produced a 7% operating margin. CS First Boston is the lead underwriter for the deal. Terms and timing have yet to be determined.
