On October 24, 2023, NYSE Group, Inc., on behalf of the Participants ^[1] to the National Market System Plan to Address Extraordinary Market Volatility (“Plan”), filed with the Securities and Exchange Commission (“Commission”), pursuant to section 11A(a)(3) of the Securities Exchange Act of 1934 ^[2] and Rule 608 of Regulation National Market System (“Regulation NMS”) thereunder,^[3] a proposal (“Proposed Amendment”) to amend the Plan. The Proposed Amendment was published for comment in the Federal Register on November 21, 2023.^[4]

On February 15, 2024, the Commission instituted proceedings pursuant to Rule 608(b)(2)(i) of Regulation NMS,^[5] to determine whether to approve or disapprove the Proposed Amendment or to approve the Proposed Amendment with any changes or subject to any conditions the Commission deems necessary or appropriate.^[6] On May 14, 2024, pursuant to Rule 608(b)(2)(i) of Regulation NMS,^[7] the Commission extended the period within which to conclude proceedings regarding the Proposed Amendment to 240 days from the date of publication of the Notice.^[8] On June 17, 2024, the Participants submitted a letter with additional information in support of the Proposed Amendment.^[9]

Rule 608(b)(2)(ii) of Regulation NMS provides that the time for conclusion of proceedings to determine whether a national market system plan or proposed amendment should be disapproved may be extended for an additional period up to 60 days (up to 300 days from the date of notice publication) if the Commission determines that a longer period is appropriate and publishes the reasons for such determination or the plan ( printed page 59779) participants consent to the longer period.^[10] The 240th day after publication of the Notice for the Proposed Amendment is July 18, 2024. The Commission is extending this 240-day period.

The Commission finds that it is appropriate to designate a longer period within which to conclude proceedings regarding the Proposed Amendment so that it has sufficient time to consider the Proposed Amendment and the comments received.^[11] Accordingly, pursuant to Rule 608(b)(2)(ii) of Regulation NMS,^[12] the Commission designates September 16, 2024, as the date by which the Commission shall conclude the proceedings to determine whether to approve or disapprove the Proposed Amendment or to approve the Proposed Amendment with any changes or subject to any conditions the Commission deems necessary or appropriate (File No. 4-631).
