     | Online During the Special Meeting: You may attend and vote online during the Special Meeting by                                                                                                                                                     
 following the instructions available at www.virtualshareholdermeeting.com/AADI2025SM. Have your proxy card in hand as you will be prompted to enter your 16-digit control number to vote at the Special Meeting. If you submit a proxy to vote your 
 shares prior to the Special Meeting and choose to attend the Special Meeting online, there is no need to vote during the Special Meeting unless you wish to revoke your prior proxy.                                                                |

If your shares are held in street name, your bank, broker or other nominee is required to vote the shares it holds on your behalf according to your instructions. These proxy materials, as well as voting and revocation - 10 -

instructions, should have been forwarded to you by the bank, broker or other nominee that holds your shares of record. In order to ensure that your shares are voted at the Special Meeting, you
will need to follow the instructions that your bank, broker or other nominee provides you. The deadlines and availability of providing voting instructions via telephone or online for beneficial owners of shares held in “street name” will
depend on the processes of the bank, broker or other nominee that holds your shares of record. Therefore, we urge you to carefully review and follow the voting instruction card and any other materials that you receive from that organization. If your
shares are held in “street name,” you must demonstrate proof of beneficial ownership to virtually attend the Special Meeting and must obtain a legal proxy from your bank, broker or other nominee to vote at the Special Meeting. In addition,
you will need your control number included on your voting instruction form in order to demonstrate proof of beneficial ownership and to be able to vote during the Special Meeting.

Even if you plan to attend the Special Meeting online, we urge you to submit a proxy to vote your shares in advance of the Special Meeting so that if you
should become unable to attend the Special Meeting your shares will be voted as directed by you.
