Zynga said Wednesday that Pincus will remain chairman of the company he founded in 2007.
Zynga went public in 2011 on the strength of games like "Farmville" and "Mafia Wars," which had enthusiastic Facebook followings. But then rival digital game makers invaded Facebook and more people migrated to other pastimes on smartphones. Zynga has been cutting jobs and posting losses.
The company is trying to shake things up. Don Mattrick, who had been in charge of Microsoft's interactive entertainment division, replaced Pincus as CEO in July. Zynga agreed to buy NaturalMotion, the company behind the hit mobile games "CSR Racing" and "Clumsy Ninja," in January.
The San Francisco-based company also announced several new executive hires on Wednesday. They include Alex Garden of Microsoft, who is now the president of Zynga Studios. Garden had been in charge of Xbox Live and Xbox Music, Video and Reading.
Including charges connected to job cuts and the closure of some data centers, Zynga said it lost $61.2 million, or 7 cents per share, in the first quarter. A year ago it earned $4.1 million and broke even on a per-share basis. Zynga said it lost a penny per share if one-time items are excluded, matching analyst expectations.
And its revenue continued to decline, dropping 36 percent to $168 million. Analysts had projected an even worse drop, to $164.2 million, according to FactSet.
The company said it had 28 million daily users in the first quarter. That's down by almost half from a year ago, but it represents growth of 1 million users compared with the fourth quarter. Zynga also raised the low end of its annual forecasts for bookings, a precursor to revenue, and for an adjusted profit measure.
Shares of Zynga jumped 23 cents, or 5.2 percent, to $4.65 in aftermarket trading. The stock had dropped 3.1 percent to $4.42 in regular trading Wednesday. It's up 39 percent over the past 12 months.
