Tradeweb Markets Inc.

Shares that are properly voted via the Internet or by telephone or for which proxy cards are properly executed and

returned will be voted at the Annual Meeting in accordance with the directions given or, in the absence of directions, will be

voted in accordance with the Board’s recommendations as follows: “FOR ALL” of the director nominees named in this Proxy

Statement, “FOR” the ratification of the appointment of our independent registered public accounting firm, “FOR” the

approval, on an advisory basis, of the compensation paid to our named executive officers, “FOR” the approval of the

Exculpation Amendment and “FOR” the approval of the Federal Forum Selection Amendment. It is not expected that any

additional matters will be brought before the Annual Meeting, but if other matters are properly presented, the persons named

as proxies in the proxy card or their substitutes will vote in their discretion on such matters.

The manner in which your shares may be voted depends on how your shares are held. If you own shares of record,

meaning that your shares are represented by certificates or book entries in your name so that you appear as a stockholder on

the records of Equiniti Trust Company, LLC, our stock transfer agent, you may vote by proxy, meaning you authorize

individuals named in the proxy card to vote your shares. You may provide this authorization by voting via the Internet, by

telephone or (if you have received paper copies of our proxy materials) by returning a proxy card. In these circumstances, if

you do not vote by proxy or virtually at the Annual Meeting, your shares will not be voted. If you own shares in street name,

meaning that your shares are held by a bank, brokerage firm or other nominee, you may instruct that institution on how to

vote your shares. You may provide these instructions by voting via the Internet, by telephone or (if you have received paper

copies of our proxy materials) by returning a voting instruction form received from that institution. In these circumstances, if

you do not provide voting instructions, we expect that the institution may nevertheless vote your shares on your behalf with

respect to the ratification of the appointment of Deloitte as our independent registered public accounting firm for the fiscal

year ending December 31, 2026, but cannot vote your shares on any other matters being considered at the Annual Meeting.

We encourage you to provide voting instructions to your bank, brokerage firm or other nominee.
