You can attend the Annual Meeting by visitingwww.virtualshareholdermeeting.com/XYZ2025, where you will be able to listen to the meeting live, submit questions, and vote your shares online during the meeting, just as you could at an in-person meeting.

We are holding the Annual Meeting for the following purposes, as more fully described in the accompanying proxy statement:

To approve the Block, Inc. Amended and Restated 2015 Employee Stock Purchase Plan; and

To transact such other business as may properly come before the Annual Meeting or any adjournments or postponements thereof.

Our board of directors has fixed the close of business on April 21, 2025 (U.S. Eastern Time) as the record date for the Annual Meeting. Only stockholders of record at the close of business on April 21, 2025 (U.S. Eastern Time) are entitled to notice of, and to vote at, the Annual Meeting. A list of stockholders entitled to vote at the Annual Meeting will be available for examination by any stockholder for any purpose germane to the Annual Meeting for a period of ten days ending the date prior to the date of the Annual Meeting at 1955 Broadway, Suite 600, Oakland, CA 94612. Further information regarding voting rights, the matters to be voted upon, and instructions to attend the Annual Meeting is presented in the accompanying proxy statement.
