Householding of Annual Meeting Materials

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of such materials may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of any such document to you if you write or call us at the following address or telephone number: RYTHM, Inc., 2220 Hicks Road, Suite 210, Rolling Meadows, IL 60008, (855) 420-0020, or you can request a copy of any such document by visiting the 2026 Annual Meeting page of our Internet website atwww.proxyvote.com. If you want to receive separate copies of the annual report or proxy statement 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 and telephone number.
