Zynga reported revenue that missed analysts’ estimates Thursday, but investors shrugged it off after the company announced it was slashing 314 jobs, or 15 percent of its work force, and buying mobile game and animation firm NaturalMotion for $527 million in a fresh reboot effort for the struggling social games pioneer.

Shares of the San Francisco-based Zynga soared 15.7 percent to $4.12 in late trading.

Zynga said it lost $25 million in the fourth quarter on revenues of $176 million.
