Zynga's shares plunged on Thursday after it handed in mixed second-quarter results and lowered its full year outlook as it battles to broaden its mobile reach and boost monthly users.
The game maker said its net profit for the second-quarter broke even, which was in line with estimates, but bookings revenue dropped nearly 7 percent to $175 million, missing Street expectations.
Moreover, the "Farmville" maker lowered its full-year guidance, citing the delayed launch of new games and features.
Zynga shares dropped as much as 10 percent in after-hours trading.
The game maker also said the number of monthly users fell to 130 million during the quarter, from 187 million a year ago.
Wall Street on average had expected bookings, an indicator of future revenue, to rise to $191.2 million in the second quarter, from $187.6 million in the same period a year earlier.
