Pursuant to Section 11A of the Securities Exchange Act of 1934 (“Act”),^[1] and Rule 608 thereunder,^[2] notice is hereby given that on September 26, 2025, the Members ^[3] in the Limited Liability Agreement of CT Plan LLC (“CT Plan”) filed with the Securities and Exchange Commission (“Commission”) a proposal to amend the CT Plan. The amendment represents the First Amendment to the CT Plan (“Amendment”). Under the Amendment, the Members propose to add 24X National Exchange LLC (“24X”) as a Member to the CT Plan and to reflect that NYSE Chicago, Inc. has changed its name to NYSE Texas, Inc.^[4]

The proposed Amendment has been filed by the Members pursuant to Rule 608(b)(3)(ii) under Regulation NMS ^[5] as concerned solely with the administration of the CT Plan and as a “Ministerial Amendment” under Section 13.5 of the CT Plan. As a result, the Amendment can be submitted by the Chair of the CT Plan's Operating Committee and becomes effective upon filing.

The Commission is publishing this notice to solicit comments on the Amendment from interested persons. Set forth in Sections I and II is the statement of the purpose and summary of the Amendment, along with the information required by Rules 608(a) and 601(a) under the Act, as prepared and submitted by the Members.

3. Implementation of Amendments

Because the amendment constitutes a “Ministerial Amendment” under Section 13.5 of the CT Plan, the Chair of the CT Plan's Operating Committee may submit the amendment to the Commission on behalf of the Members in the CT Plan.
