NEW YORK ( TheStreet) -- Zynga ( ZNGA) was a big gainer in premarket trading on Wednesday after the company allayed investors' fears and beat Wall Street's fourth-quarter estimates. Zynga reported earnings Tuesday of a penny a share and revenue of $311.1 million. Analysts surveyed by Thomson Reuters were looking for a loss of 3 cents a share and sales of $212.1 million. The San Francisco-based firm, which is keen to cut costs, said that its fourth-quarter headcount was 3,058, down 251 people sequentially. The key Facebook ( FB) partner reduced its cash operating expense by $23 million from the third quarter, surpassing its projected cost savings range of $15 million to $20 million. "We decreased spend in a number of areas, including marketing acquisition, data hosting, and outside services," said Zynga Chief Operating Officer David Ko, during the company's earnings conference call. "We also closed several remote studios, reduced the size of our work force, and rationalized our product pipeline."
