Deferred compensation is pay that employees or executives have earned now but will receive at a later date, such as delayed bonuses, retirement benefits, or stock grants. It matters to investors because it creates future obligations and shapes incentives—like a promise to pay later that can affect a company’s reported profits, cash needs and potential stock dilution—so it helps signal how a business manages costs and retains key people.

Explanation of Responses:

1. These deferred compensation notional units were allocated under the Fiserv, Inc. Non-Employee Director Deferred Compensation Plan (the "Plan"), under which director fees otherwise payable in cash may be deferred in exchange for the allocation of notional units under the Plan. This Form 4 reports the crediting of units under the Plan on March 31, 2026, in respect of $32,500 of deferred compensation. The number of notional units credited is calculated by dividing the amount of compensation that is deferred by the closing price of the company's common stock on the date of deferral, or last business day prior. On March 31, 2026, the closing price of Fiserv's common stock was $55.80 per share. Following cessation of the reporting person's service to the company, each notional unit will be settled in shares of Fiserv common stock on a one-for-one basis.
