In addition to complying with this deadline, stockholder proposals intended to be considered for inclusion in the proxy materials for our 2024 Annual Meeting must also comply with our bylaws and all applicable rules and regulations promulgated by the Securities and Exchange Commission under the Exchange Act. Additionally, any stockholder who intends to submit a proposal regarding a director nomination or any other matter of business at our 2024 Annual Meeting not to be included in our proxy materials for our 2024 Annual Meeting, must also ensure that notice of any such proposal (including any additional information specified in our bylaws) is received by our Corporate Secretary at our principal executive offices by the close of business on April 9, 2024.
