Dear Takis:

On behalf of the Board of Directors of Fiserv, Inc. (“Fiserv”), I am pleased to offer you the role of Chief Executive Officer. As Chief Executive Officer you will remain a member of the Management Committee and will report directly to the Fiserv Board of Directors (the “Board”).

Annual Compensation Package. Your total annual compensation opportunity will be $22,500,000 and will be provided in the following components:

 

   

Annual Base Salary: Your annual base salary for 2026 will be $1,300,000, which is $50,000 per pay period, which will be subject to review by the Talent and Compensation Committee of the Board (the “Committee”) on an annual basis and which may be increased from time to time, but shall not be decreased.

 

   

Incentive Compensation Opportunity: Fiserv’s incentive compensation opportunity is paid as a mix of cash compensation and equity awards. You will be eligible to receive annual incentive compensation including annual cash incentives and annual grants of equity awards under Fiserv’s Amended and Restated 2007 Omnibus Incentive Plan or any successor plan thereto (the “Plan”) as approved by the Board (or the Committee) from time to time.

 

   

Your target annual cash incentive compensation opportunity will be 200% of your then-current base salary, or $2,600,000 based on a base salary of $1,300,000. The cash component of your incentive compensation opportunity will be determined annually consistent with other members of the Management Committee and will range from 0% to 200% of the target opportunity based on company and individual performance.

 

   

Your annual equity incentive compensation opportunity will be $18,600,000, which for awards granted in 2027, will be delivered as 60% Performance Share Units (“PSUs”) and 40% Restricted Stock Units (“RSUs”). Subject to your continued employment, the terms of the applicable incentive compensation plan(s), and acknowledgment of the equity award agreements, the RSUs will vest 33% on the first three anniversaries of the grant date and the PSUs will cliff vest after three years based upon certification of achievement of the PSU performance goals and contain substantially the same terms as the PSU awards granted to the other members of the Management Committee. For annual equity awards granted in 2028 and future years, the amount, structure, and form of any incentive compensation opportunity will be subject to all terms and conditions


 

of the applicable incentive compensation plan(s) and equity award agreements and will be determined by Fiserv in its sole discretion, which includes the right to provide a different equity award mix or different terms and conditions than those described above. The incentive compensation opportunity depends on achievement of corporate objectives as determined by the Board in its discretion, and further adjusted to reflect individual performance. Finally, to the extent permitted by law, all equity award agreements will contain post-employment obligations including non-disclosure, non-compete, and non-solicitation (of employees and clients) obligations provided that such postemployment obligations will be no more restrictive to you than as currently provided under Fiserv’s current equity award forms applicable to executives.

Equity Award. On June 15, 2026, in recognition of your promotion to Chief Executive Officer, you will receive equity awards with a total grant date value of $6,000,000, delivered 60% in the form of PSUs ($3,600,000) and 40% in the form of RSUs ($2,400,000). The PSUs and RSUs comprising this award will be in the same form and contain the same terms as those Fiserv equity awards granted to you and other members of the Management Committee on February 18, 2026, provided that such RSUs shall vest as to 33% of the award on each of the first three anniversaries of the grant date.

Executive Severance Policy. Your entitlement to severance benefits will continue to be governed by the Fiserv, Inc. Executive Severance and Change of Control Policy (as modified by the terms of this letter, the “Executive Severance Policy”), provided that your cash severance benefit under the Executive Severance Policy will be 2.0 times your then-current annual base salary and target cash incentive, instead of 1.5 times.
