The following communication was first made available to employees of Zynga Inc. May 2nd, 2022:

Hi everyone -

I’m excited to provide a brief update on the progress of the transaction to combine Zynga with Take-Two Interactive Software. As we recently disclosed, I am happy to share that we received the regulatory approvals required to complete the transaction and both Zynga and Take-Two will host our respective shareholder votes to approve the deal on May 19, 2022. On this date, if both groups vote in favor of the transaction, the deal will be ready to close shortly thereafter, subject to satisfaction of the remaining customary closing conditions.

So, what does this mean for you? Between now and closing, our integration teams will continue to plan for a seamless transition to becoming a Take-Two label starting on day one. This includes preparing for the integration of our core business operations like financial systems and stock programs as well as defining the overarching structure of the combined organization. You can expect communications about these in the coming weeks. There are also two important near-term next steps:

Zynga Shareholder Vote

If you are an owner of Zynga stock and held shares on April 4, you should have received a communication from your broker with instructions about how to submit your vote for the proposed deal. If you have any questions, please contact your broker or stockadmin@zynga.com. As a reminder, Zynga’s board of directors recommends that all Zynga stockholders vote in favor of the transaction at our special meeting.

Culture Survey

As we look to make our combined organization the best it can be, we are focused on preserving and enhancing the best elements of both companies’ cultures. Our goal is to create the best experience for our teams.

To this end, we are launching a culture assessment survey with a focus on identifying the unique aspects that drive creativity, innovation and efficiency. This survey will come in an email from Jeff Ryan. I ask that you take a few minutes to share your input for this important work and know that your responses will be anonymous.

I want to reiterate my excitement surrounding this deal. Combining Zynga’s expertise in mobile and our next generation platforms with Take-Two’s best-in-class capabilities and intellectual property will transform us into a global interactive entertainment leader with a portfolio of iconic franchises. Your dedication and hard work are what enable us to continue to raise the bar and deliver an unmatched gaming experience for our players. Every day, I am proud to be on this journey with the Zynga team. Thank you for all that you do.

Frank
