“Over the last 7 months, our teams have been working with a sense of urgency. We finished 2013 in a strong position and expect 2014 to be a growth year. We believe that Q1 will be a solid foundation for that growth and we expect substantial improvements for the remainder of the year across audience, bookings and Adjusted EBITDA. The investments we are making to grow and sustain our franchises are beginning to bear fruit, particularly in Zynga Casino and Words With Friends. We are committed to refining our skills in the art and science of building new hit games and in 2014, we will move aggressively into new genres that align with the timeless, entertainment categories that consumers care about. Our market is growing as measured by device, audience and dollars and we have the privilege to compete in one of the fastest growing parts of the entertainment industry. We have an ambitious agenda and we are moving quickly to add capabilities that are complementary and strategic to our core growth plans,” said Don Mattrick, CEO of Zynga.

Zynga to Acquire Leading Mobile Game Developer NaturalMotion

Zynga also announced today, an agreement to acquire privately-held NaturalMotion, a leading mobile game and technology developer for approximately $527 million in cash and equity, based on Zynga’s closing price on January 29, 2014. NaturalMotion is led by a seasoned team of technology innovators, including Chief Executive Officer and Co-Founder Torsten Reil and Vice President of Games Barclay Deeming. NaturalMotion was founded in 2001 and has approximately 260 employees across Oxford, Brighton, London and San Francisco.

Key Business Terms

Strategic Rationale

“We believe that bringing Zynga and NaturalMotion together is the right step at the right time,” said Mattrick. “Our acquisition of NaturalMotion will allow us to significantly expand our creative pipeline, accelerate our mobile growth and bring next-generation technology and tools to Zynga that we believe will fast track our ability to deliver more hit games. Their creative portfolio aligns perfectly with our content strategy as Zynga will now have five top brands and capabilities in the Farm, Casino, Words, Racing and People categories. We are confident that we will build upon our market position with complementary strengths to generate long term value for our consumers, our employees and our shareholders.”

“NaturalMotion set out to make games that wow millions of people, by being obsessed with quality, disrupting and creating genres, and using almost magical technology. When we started talking to Don and his team, it quickly became clear that they shared this vision. Don’s background in AAA games and Zynga’s expertise in social game play and large-scale game operations will be invaluable to helping us grow our existing CSR and Clumsy Ninja franchises and maximize the breakout potential of our upcoming titles. We’ve reached our first milestones – creating #1 top-grossing and top-free titles – on our own. We can’t wait to see what we can achieve together with Zynga,” said Torsten Reil, CEO and Co-Founder, NaturalMotion

Forward-looking statements often include words such as “outlook,” “projected,” “intends,” “will,” “anticipate,” “believe,” “target,” “expect,” and statements in the future tense are generally forward-looking statements. The achievement or success of the matters covered by such forward-looking statements involves significant risks, uncertainties, and assumptions. Our actual results could differ materially from those predicted or implied, and reported results should not be considered as an indication of our future performance. Factors that could cause or contribute to such differences include, but are not limited to, our relationship with Facebook or changes in the Facebook platform, delays or other challenges in the completion of the NaturalMotion acquisition, its integration and the success of its current and future games as part of Zynga, delays or challenges in implementing our reduction in force or other cost-cutting activities, attrition and declines in our existing games, our ability to launch new games in a timely manner and monetize these games effectively on the web and on mobile, our ability to control and reduce expenses, our exposure to illegitimate credit card activity and other security risks, sales or purchases of virtual goods used in Zynga Poker or our other games through unauthorized or fraudulent third-party websites, our ability to anticipate and address technical challenges that may arise, competition, changing interests of players, intellectual property disputes or other litigation, asset impairment charges, our ability to retain key employees, acquisitions by us, and changes in corporate strategy or management.

More information about factors that could affect our operating results is included under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Quarterly Report on Form 10-Q for the three months ended September 30, 2013 and in our Annual Report on Form 10-K for the year ended December 31, 2012, copies of which may be obtained by visiting our Investor Relations web site at http://investor.zynga.com or the SEC’s web site at www.sec.gov. Undue reliance should not be placed on the forward-looking statements in this release, which are based on information available to us on the date hereof. There is no guarantee that the circumstances described in our forward-looking statements will occur. We assume no obligation to update such statements. The results we report in our Annual Report on Form 10-K for the year ended December 31, 2013 could differ from the preliminary results we have announced in this press release.

Non-GAAP Financial Measures:

We have provided in this release non-GAAP financial information including bookings, Adjusted EBITDA, free cash flow, non-GAAP net income and non-GAAP EPS, as a supplement to the consolidated financial statements, which are prepared in accordance with generally accepted accounting principles (“GAAP”). Management uses these non-GAAP

5

financial measures internally in analyzing our financial results to assess operational performance and liquidity. The presentation of this financial information is not intended to be considered in isolation or as a substitute for the financial information prepared in accordance with GAAP. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods. We believe these non-GAAP financial measures are useful to investors because they allow for greater transparency with respect to key financial metrics we use in making operating decisions and because our investors and analysts use them to help assess the health of our business. We have provided reconciliations between our historical and first quarter 2014 outlook for non-GAAP financial measures to the most directly comparable GAAP financial measures. However, we have not provided reconciliation of full year 2014 bookings outlook to revenue, Adjusted EBITDA outlook to net income (loss), non-GAAP effective tax rate outlook to GAAP effective tax rate or non-GAAP EPS outlook to GAAP EPS because certain reconciling items necessary to accurately project revenue (including the projected mix of virtual goods sold in our games, and the projected estimated average lives of durable virtual goods for our games) for a full year are not in our control and cannot be reasonably projected due to variability from period to period caused by changes in player behavior and other factors. As revenue and/or net income for the applicable future period is a necessary input to determine all of these comparable GAAP figures, we are not able to provide these reconciliations for the full year 2014. For the same reason, we have also not provided a reconciliation of our outlook for the impact on bookings, Adjust EBITDA and non-GAAP EPS related to the NaturalMotion acquisition.

Some limitations of bookings, Adjusted EBITDA, non-GAAP net income, non-GAAP EPS, and free cash flow:

Because of these limitations, you should consider bookings, Adjusted EBITDA, non-GAAP net income (loss), non-GAAP EPS, and free cash flow, along with other financial performance measures, including revenue, net income (loss), diluted net loss per share, cash flow from operations and GAAP operating margin and our other financial results presented in accordance with GAAP. See the GAAP to non-GAAP reconciliations below for further details.
