Accompanying this proxy statement and posted on the investor relations portion of our website at www.rocketpharma.com with this proxy statement, is our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The inclusion of our website address here and elsewhere in this proxy statement does not include or incorporate by reference the information on our website into this proxy statement. We will also mail without charge, upon written request, a copy of that Annual Report excluding exhibits.

Stockholders residing in the same household who hold their stock through a bank or broker may receive only one set of proxy materials in accordance with a notice sent earlier by their bank or broker unless we have received contrary instructions from one or more of the stockholders. This practice will continue unless instructions to the contrary are received by your bank or broker from one or more of the stockholders within the household. We will promptly deliver a separate copy of the Notice of Internet Availability or the proxy materials, as applicable, to such stockholders if you make a written or oral request to our corporate secretary at the address above, or by calling (609) 659-8001.

If you hold your shares in “street name” and reside in a household that received only one copy of the proxy materials, you can request to receive a separate copy in the future by following the instructions sent by your bank or broker. If your household is receiving multiple copies of the Notice of Internet Availability or the proxy materials, you may request that only a single set of materials be sent by following the instructions sent by your bank or broker.
