King Digital Entertainment PLC (NYSE:KING) shares slipped -10.46% in pre-market trading, after the company posted a 28 percent drop in quarterly profit, as revenue from its three-year-old “Candy Crush Saga” game continued to decline. In response, RBC Capital analyst Mark Mahaney commented: “We’ve stated before that for us to become constructive on the stock, we would need to see stable trends showing bookings growth AND diversification away from CC. This quarter we saw both Gross Bookings declines and a decrease in diversification away from CC… Uh-Oh. This coupled with a weak bookings outlook for the year and weak usage metrics makes us more cautious.”
