Alongside its first quarter financial results, the mobile publisher today announced that it has reached an agreement to acquire the entirety of Chartboost for $250 million in cash, with the deal expected to close in the third quarter of this year. "Chartboost is one of the most dynamic monetization and discovery platforms in mobile, and we could not be more excited to welcome their talented team to our company," Zynga CEO Frank Gibeau said. "By combining Zynga's high-quality games portfolio and first-party data with Chartboost's proven advertising and monetization platform, we will create a new level of audience scale and meaningfully enhance our competitive advantage in the mobile ecosystem."
