Egypt's Palm Hills , the country's second biggest listed developer, dropped to a nine-month net loss, the stock exchange said on Thursday. The firm, battered by land probes and cancellations after the uprising that toppled Hosni Mubarak in February, posted a 99.1 million Egyptian pound ($16.6 million) net loss for the first nine months of 2011, compared to a 345.1 million net profit for the same period a year earlier.
