Nasdaq PHLX Proposes Adding TXSE to Data Feeds Table

Content

April 16, 2026. Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) (1), and Rule 19b-4 thereunder, (2) notice is hereby given that on April 6, 2026, Nasdaq PHLX LLC (“PHLX” or “Exchange”) filed with the Securities and Exchange
Commission (“SEC” or “Commission”) the proposed rule change as described in Items I, II, and III, below, which Items have
been prepared by the Exchange. The Commission is publishing this notice to solicit comments on the proposed rule change from
interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

The Exchange proposes to amend Equity 4, Rule 3304 (Data Feeds Utilized) to establish a primary and secondary source of quotation
data of a new market center in the list of proprietary and network processor feeds that the Exchange utilizes for the handling,
routing, and execution of orders, as well as regulatory compliance processes related to those functions.

The text of the proposed rule change is available on the Exchange's website at https://listingcenter.nasdaq.com/rulebook/phlx/rulefilings, and at the principal office of the Exchange.

II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule
change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at
the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the
most significant aspects of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to update and amend the data feeds table in Equity 4, Rule 3304, which sets forth on a market-by-market
basis the specific proprietary and network processor feeds that the Exchange utilizes for the handling, routing, and execution
of orders, and for performing the regulatory compliance processes related to each of those functions. Specifically, the table
would be amended to reflect that the Exchange will receive a direct feed from the new Texas Stock Exchange (“TXSE”) as its
primary quotation data source for TXSE, and the Exchange will use CQS/UQDF as the secondary data source for TXSE. Additionally,
the table will be updated to reflect the current names of two exchanges that were recently renamed (i.e.: Nasdaq Texas and NYSE Texas).

2. Statutory Basis

The Exchange believes that its proposal is consistent with Section 6(b) of the Act, (3) in general, and furthers the objectives of Section 6(b)(5) of the Act, (4) in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect
the mechanism of a free and open market and a national market system, and, in general to protect investors and the public
interest.

The Exchange believes that the proposed rule change removes impediments to and perfects the mechanism of a free and open market
because updating its data feeds table to add a new market center for which the exchange will consume quotation data through
direct and secondary feeds will provide clarity to market participants. Additionally, it is necessary and consistent with
the public interest and the protection of investors to update the Exchange's table of market centers in Equity 4, Rule 3304
in order to provide transparency with respect to all the direct proprietary and network processor feeds from which the Exchange
obtains market data. Finally, it will promote just and equitable principles of trade and protect investors and the public
interest to update the table in Equity 4, Rule 3304, to reflect the current names of two recently-renamed exchanges.

B. Self-Regulatory Organization's Statement on Burden on Competition

The Exchange does not believe that the proposed rule change will impose any burden on competition not necessary or appropriate
in furtherance of the purposes of the Act. The proposed rule change is not designed to address any competitive issue; instead,
its purpose is to enhance transparency with respect to the operation of the Exchange and its use of market data feeds.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or

Others

No written comments were either solicited or received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

Because the foregoing proposed rule change does not: (i) significantly affect the protection of investors or the public interest;
(ii) impose any significant burden on competition; and (iii) become operative for 30 days from the date on which it was filed,
or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A)(iii) of the
Act (5) and subparagraph (f)(6) of Rule 19b-4 thereunder. (6)

At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such
rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection
of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission
shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
