We expect the transaction to close during the second half of 2019, subject to customary closing conditions and regulatory approvals, including the approval of shareholders of both companies. Both companies will continue to operate separately until the transaction is complete.

What are the plans to integrate the two companies?

There are many reasons to be excited about this announcement, yet until the transaction closes, Fiserv and First Data will continue to operate as independent companies.

Fiserv President and CEO Jeff Yabuki will serve as Chief Executive Officer and Chairman of the board of the combined company. Frank Bisignano, First Data Chairman and Chief Executive Officer, will become President and Chief Operating Officer, and will serve as a director on the board of the combined company.

Will there be other changes to the Fiserv senior executive team?

Until the transaction closes, we will continue to operate as independent companies.

How will this affect me?

Many associates are wondering about the new organization, their benefits and other aspects of this acquisition that may affect them professionally and personally. One of the things to keep in mind is that until the transaction closes, we will continue to operate as independent companies, so there should be minimal, if any, impacts to you during the post-announcement period. That said, integration planning is beginning immediately, and our teams have a strong track record of successfully integrating companies. Answers to many of your questions will be formulated during that process. We plan to leverage our collective experience to maintain a strong workforce and determine the best organizational structure for the combined entity. With any combination of this size and magnitude, we expect there will be some overlap in job functions and responsibilities. Please keep in mind that we are in the early stages of the process and it is therefore premature to discuss any role changes. As we can share more information with you, we will; but you should know that many answers to questions you may have won’t be available until after the transaction is closed.

Will this transaction impact my office location?

There are many reasons to be excited about this announcement, yet until the transaction closes, Fiserv and First Data will continue to operate as independent companies. Fiserv and First Data continue to remain committed to numerous communities in which we operate around the world.

Will there be changes to associate compensation, benefits and plans?

Until the transaction closes, Fiserv and First Data will continue to operate as independent companies and we anticipate no changes to our health and welfare benefits through 2019.

Benefits and compensation of the combined company will continue to be comprehensive and competitive; however, it is early in the process and more details with respect to future compensation and benefits will be determined and communicated to you as they are finalized.

How soon can Fiserv associates interact with First Data associates?

There are many reasons to be excited about this announcement, yet until the transaction closes, Fiserv and First Data will continue to operate as independent companies.
