We are furnishing proxy materials to some of our stockholders via the Internet by mailing the Notice instead of mailing

printed copies of those materials. The Notice directs stockholders to a website where they can access our proxy materials,

including this Proxy Statement and our combined Annual Report to Stockholders and Annual Report on Form 10-K for the

fiscal year ended December 31, 2024 (the "2024 Annual Report") and view instructions on how to vote via the Internet or by

telephone. If you received a Notice and would prefer to receive a paper copy of our proxy materials, please follow the

instructions included in the Notice. If you elect to receive our future proxy materials electronically, you will receive access to

those materials via email unless and until you elect otherwise.
