Self-Regulatory Organization's Statement of the Purpose of, and the Statutory Basis for, the Proposed Rule Change</HD> <HD SOURCE="HD3">1. Purpose</HD> <HD SOURCE="HD3">Addition of 24X</HD> The Exchange proposes to amend IEX Rules 2.220(a)(7)  <SU>6</SU> <FTREF/> and 11.410(a)  <SU>7</SU> <FTREF/> to include 24X in the list of away trading centers to which the Exchange routes and the market data sources the Exchange will use to determine Top of Book  <SU>8</SU> <FTREF/> quotations, the NBBO  <SU>9</SU> <FTREF/> and certain regulatory, reporting and compliance systems within IEX in anticipation of 24X's planned exchange launch on September 29, 2025. <SU>10</SU> <FTREF/> The Exchange proposes to amend the IEX Rule 2.220(a)(7) to add 24X to the list of away trading centers to which IEX Services routes orders. As set forth in IEX Rule 11.230(b)(2), IEX Services routes eligible orders to away trading centers with accessible Protected Quotations in compliance with Regulation NMS Rule 611. <SU>11</SU> <FTREF/> IEX Rule 2.220(a)(7) lists the away trading centers that IEX Services routes to as outbound router for the Exchange. The Exchange must include 24X in its list of away trading centers to which it routes because 24X's best-priced, displayed quotation will be a Protected Quotation under Regulation NMS Rule 600(b)(62)  <SU>12</SU> <FTREF/> for purposes of Regulation NMS Rule 611. <SU>13</SU> <FTREF/> <FTNT> <SU>6</SU>  IEX Rule 2.220(a)(7) lists the away trading centers that IEX Services LLC (“IEX Services”) routes to as outbound router for the Exchange. </FTNT> <FTNT> <SU>7</SU>  IEX Rule 11.410(a) specifies the market data sources for each away trading center that the Exchange uses for necessary price reference points. </FTNT> <FTNT> <SU>8</SU>   <E T="03">See</E> IEX Rule 11.410w. </FTNT> <FTNT> <SU>9</SU>   <E T="03">See</E> IEX Rule 1.160(u). </FTNT> <FTNT> <SU>10</SU>   <E T="03">See</E> 24X press release available at <E T="03">https://24exchange.com/trading-on-24x-national-exchange-set-to-commence-in-september/</E> . </FTNT> <FTNT> <SU>11</SU>  17 CFR 242.611. </FTNT> <FTNT> <SU>12</SU>  17 CFR 242.600(b)(62). </FTNT> <FTNT> <SU>13</SU>   <E T="03">See</E> Securities Exchange Act Release No.101777 (November 27, 2024), 89 FR 97092 (December 6, 2024) (Order approving 24X Exchange application for registration as a national securities exchange). </FTNT> The Exchange also proposes to amend and update the table in IEX Rule 11.410(a) specifying the primary source for 24X market data. IEX Rule 11.410(a) lists the specific data feeds the Exchange uses to determine Top of Book quotations for away exchanges, the NBBO and for certain reporting, regulatory and compliance systems within IEX. The Exchange proposes to amend the table in IEX Rule 11.410(a) to specify that the Exchange will use securities information processor (“SIP”) data, <E T="03">i.e.,</E> CQS SIP data for securities reported under the Consolidated Quotation Services and Consolidated Tape Association plans and UQDF SIP data for securities reported under the Nasdaq Unlisted Trading Privileges plan, as the primary source of market data used to determine 24X's Top of Book quotes. The Exchange also proposes to make a conforming change to Rule 11.410(a)(2) so that the provision is consistent with the table in Rule 11.410(a). The Exchange proposes to make these changes operative on the date that 24X launches operations. <HD SOURCE="HD3">NYSE Chicago to NYSE Texas Name Change</HD> NYSE Chicago, Inc. recently converted from a corporation organized under the laws of the state of Delaware to one organized under the laws of the state of Texas and changed its name to “NYSE Texas, Inc.”  <SU>14</SU> <FTREF/> The Exchange proposes conforming changes to its rules to reflect this name change by amending Rules 2.220(a)(7) and 11.410(a) to reflect the name change of “NYSE Chicago” to “NYSE Texas.” As discussed above, IEX Rule 2.220(a)(7) lists the away trading centers that IEX Services routes to as outbound router for the Exchange and Rule 11.410(a) specifies the market data sources for each away trading center that the Exchange uses for necessary price reference points. <FTNT> <SU>14</SU>   <E T="03">See</E> Securities Exchange Act Release No. 102507 (February 28, 2025), 90 FR 11445 (March 6, 2025) (SR-NYSECHX-2025-01). </FTNT> Specifically, the Exchange proposes to amend Rule 2.220(a)(7) by replacing the reference to “NYSE Chicago” with “NYSE Texas” in the list of away trading centers to which IEX Services routes orders. In addition, the Exchange proposes to amend Rule 11.410(a) by replacing the reference to “NYSE Chicago” with “NYSE Texas” in the table the market data sources the Exchange uses to determine its Top of Book quotation, NBBO and for certain reporting, regulatory and compliance systems within IEX. The Exchange will continue to utilize the SIP data feeds for NYSE Texas, as it did for NYSE Chicago, as set forth in Rule 11.410(a)(2). The Exchange is not proposing any other changes to IEX Rules 2.220(a)(7) and 11.410. The proposed changes do not alter the manner in which orders are handled or routed by the Exchange. <HD SOURCE="HD3">2.
