Withdrawal of
Proposal No. 6
After discussions with As You Sow regarding its shareholder proposal requesting that Twitter issue a report on the companys
climate change policies, As You Sow has agreed to withdraw their proposal given Twitters efforts towards sustainability, including announcing our pledge to set a target validated by the Science Based Targets Initiative and publishing our first
Global Impact Report which can be found here: https://blog.twitter.com/en_us/topics/company/2021/introducing-twitters-global-impact-report.html. Twitter remains committed to these efforts and continuing our dialogue with As You Sow on our
progress. In light of As You Sows withdrawal, Proposal No. 6 in the Notice and Proxy Statement will not be voted upon at the Annual Meeting. All other agenda items remain the same, and stockholders may continue to use the form of proxy
card distributed with the Notice and any subsequent mailing of proxy materials.
