PayPal's increasingly star-crossed IPO is still expected to price this week, syndicate sources say, but serious doubts exist as to whether it can stand any more surprises. The company, which sells an electronic-payment service that is popular with users of eBay ( EBAY), dropped two more bombs in an amendment to its registration filing Monday with the Securities and Exchange Commission. PayPal said in the filing that the state of Louisiana had ordered it to stop providing its service there until it obtains a money-transmission license. In fact, Louisiana, California, New York and Idaho all have notified the company that they believe it is or may be an unauthorized banking business. The company said it has taken steps to address the states' concerns but can't be sure they'll work. "This could end up being a long row of dominoes, if other states pick up on it," said David Menlow, president of IPOfinancial.com. "A complaint like this is very detrimental to the stock. "Right now, the perception is PayPal's revenue-growth curve is shaped like a hockey stick," said Menlow. "If there's concern Louisiana isn't going to be the only state barring transactions, it could sour people from the aggressive posturing they've had on this offering."
