Notes FORM OF PROXY 1. As an Abcam Shareholder you are entitled to appoint a proxy or proxies to exercise all or any of your rights to attend, speak and vote at the General Meeting of the Company. You can only appoint a proxy using the procedures set out in these notes. If the proxy is being appointed in relation to part of your holding only, please enter in the box next to the proxy’s name (headed “Number of Abcam Shares”) the number of Abcam Shares in relation to which they are authorised to act as your proxy. If this box is left blank they will be authorised in respect of your full voting entitlement. This form of proxy confers authority to demand or join in demanding a poll. 2. Appointment of a proxy does not preclude you from attending the General Meeting and voting in person. If you have appointed a proxy and attend the General Meeting in person and vote, your proxy appointment will automatically be terminated. APPOINTMENT 3. A proxy needs not be a registered shareholder of the Company but they must attend the General Meeting to represent you. If you wish to appoint a proxy other than the Chairman of the General Meeting, insert their full name in the box (headed “Name of proxy”). If you leave this space blank, the Chairman of the General Meeting will be appointed your proxy. Where you appoint as your proxy someone other than the Chairman, you are responsible for ensuring that they attend the General Meeting and are aware of your voting intentions. If you wish your proxy to make any comments on your behalf, you will need to appoint someone other than the Chairman and give them the relevant instructions directly. 4. If you are appointing more than one proxy, please indicate in the box next to the proxy holder’s name the number of Abcam Shares in relation to which they are authorised to act as your proxy (which, in aggregate, should not exceed the number of Abcam Shares held by you) and indicate by ticking the relevant box that the proxy appointment is one of multiple appointments being made. You may not appoint more than one proxy to exercise rights attached to any one Abcam Share. If you require additional proxy forms, please contact the Company’s registrars, Equiniti on +44 (0) 371 384 2050 (if calling from outside the U.K. international rates apply) or by submitting a request in writing to Equiniti at Freepost RTHJ-CLLL-KBKU, Equiniti, Aspect House, Spencer Road, Lancing, West Sussex BN99 8LU.

In the case of joint holders of an Abcam Share, the vote of the joint holder whose name stands first in the register of members of the Company in respect of the joint holding shall be accepted to the exclusion of the votes of the other joint holder(s). VOTING DIRECTIONS 6. To direct your proxy how to vote on the resolution mark the appropriate box with an ‘X’. To abstain from voting on the resolution, select the relevant “Vote Withheld” box. A vote withheld is not a vote in law, which means that the vote will not be counted in the calculation of votes for or against the resolution. If no voting indication is given, your proxy will vote or abstain from voting at his or her discretion. Your proxy will vote (or abstain from voting) as he or she thinks fit in relation to any other matter which is put before the General Meeting, including a motion to adjourn.
