Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports.

We will promptly deliver a separate copy of either document to you if you contact us at: Mustang Bio, Inc., 95 Sawyer Road, Suite 110, Waltham, Massachusetts 02453, Attn: Corporate Secretary. You may also contact us at (781) 652-4500.

If you want to receive separate copies of the Internet Notice, or proxy statement and annual report in the future, or if you are receiving multiple copies and would like to receive only one copy for your household, you should contact your bank, broker, or other nominee record holder, or you may contact us at the above address or phone number.
