Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),^[1] and Rule 19b-4 thereunder,^[2] notice is hereby given that on August 20, 2026, Cboe EDGA Exchange, Inc. (the “Exchange” or “EDGA”) filed with the Securities and Exchange Commission (the “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 its fee schedule to implement an Exchange Order Entry Protocol Migration Program. The text of the proposed rule change is also available on the Commission's website ( www.sec.gov/​rules/​sro.shtml), the Exchange's website ( www.cboe.com/​us/​equities/​regulation/​rule_​filings/​edga/​), 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 purpose of the proposed rule change is to introduce the Exchange's Order Entry Protocol Migration Program (the, “Program”). As described in further detail below, the Program is intended to provide Members,^[3] subject to certain conditions, fee credits for logical ports that Members establish solely for use as a back-up connection during an Exchange initiated order entry protocol migration; e.g., migrating from BOEv2 ^[4] logical ports to BOEv3 logical ports.

Specifically, the proposed Program would provide that during an Exchange initiated order entry protocol migration (“Migration”) a Member may establish a logical port to serve solely as a backup connection (“Redundant Logical Port”) during the Member's migration from a prior logical port protocol to the current logical port protocol (“New Logical Port”). The Redundant Logical Port may only be used for Exchange issues directly related to the Migration that prevent the Member from using their New Logical Port, thereby requiring the Member to instead use their Redundant Logical Port to enter orders and/or quotes into the System.^[5] A Member shall be eligible for a credit of the monthly logical port fee(s) that would otherwise be assessed for such Redundant Logical Port, provided that: (i) the Member notifies the Exchange's Trade Desk, in a manner specified by the Exchange, that the Redundant Logical Port being established is intended to serve only as a backup connection during a Migration; (ii) the Redundant Logical Port is canceled by the Member within 30 calendar days of the Member designating such logical ( printed page 56534) port as a Redundant Logical Port; (iii) any orders and/or quotes entered by the Member into the Redundant Logical Port must be due to an Exchange issue directly related to the Migration; and (iv) within 30 days following such cancelation, the Member submits to the Exchange's Trade Desk a request for a credit of the fees assessed by the Exchange for the Redundant Logical Port.

Following receipt of the credit request, the Exchange will review the Redundant Logical Port's order and quote usage for the period during which the Redundant Logical Port was designated as such and confirm the Member's compliance with (i)-(iv), above. If the Member satisfies these requirements the Exchange will apply a credit for the fees assessed for the Redundant Logical Port to the Member's invoice for the billing cycle following the Exchange's confirmation.

The Exchange is implementing the Program to credit logical port fees back to Members where their establishment of a Redundant Logical Port was solely for the purpose of creating backup logical ports to be used in the event a Member's New Logical Port, through no fault of their own, is not available for use, thereby preventing their access to the Exchange. In this regard, by creating Redundant Logical Ports, Members can responsibly ensure that they will maintain access to the Exchange even in the event where their New Logical Ports, which were created only because of an Exchange initiated order entry protocol migration, are not available for use because of an Exchange issue ( e.g., through clerical or ministerial error, a Member's New Logical Port was not created by the Exchange). In such a scenario, the Exchange does not believe it appropriate to assess Members logical port fees for Redundant Logical Port fees that are, absent an Exchange issue, not being utilized and instead are being created by Members to responsibly ensure they always maintain access to the Exchange.

2. Statutory Basis

The Exchange believes the proposed rule change is consistent with the Securities Exchange Act of 1934 (the “Act”) and the rules and regulations thereunder applicable to the Exchange and, in particular, the requirements of Section 6(b) of the Act. Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) requirements that the rules of an exchange be designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, 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. Additionally, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) requirement that the rules of an exchange not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers.

The Exchange believes it is reasonable to provide a credit of the applicable monthly logical port fees only where a Member establishes a Redundant Logical Port in connection with Migration. In this circumstance, the Member is adopting a New Logical Port not as a matter of its own business discretion, but solely because the Exchange has elected to migrate to an updated order entry protocol. The Redundant Logical Port that a Member maintains during such a transition is therefore directly attributable to an Exchange driven change and exists solely to preserve the Member's continued access to the Exchange in the event the Member's New Logical Port, through no fault of the Member, does not function as intended due to an Exchange Migration issue. By contrast, the Exchange does not believe it would be reasonable or appropriate to extend the credit to a logical port that a Member establishes in connection with a Member initiated change, because in that case the additional connection reflects the Member's own operational preferences and business decisions ( e.g., migrating from FIX ports to BOE ports) rather than a transition necessitated by the Exchange. Limiting the credit to a Migration thus appropriately ties the fee credit to the specific circumstance the Program is designed to address, namely, the operational burden placed on Members as a direct result of the Exchange's decision to migrate to a new order entry protocol.

The Exchange further believes that the 30-calendar day period during which a Member may maintain a Redundant Logical Port and remain eligible for the credit is reasonable. A migration to a new order entry protocol presents operational risk for Members, and the 30-calendar day overlap period affords Members an adequate opportunity to establish, test, and gain confidence in the operation of their New Logical Port before decommissioning the logical port that supported the prior protocol. Permitting this limited period of overlap reduces the risk that a Member will prematurely cancel a functioning connection and thereby jeopardize its access to the Exchange during a critical transition. At the same time, the Exchange believes 30-calendar days is an appropriately tailored period that is long enough to allow Members to develop confidence in the New Logical Port, while ensuring that the credit remains tied to the migration and is not used to subsidize a Member's maintenance of duplicative connectivity on an indefinite basis. The Exchange also believes that measuring this period in calendar days, rather than business days, promotes clarity and ease of administration for both Members and the Exchange as it removes the need to have to account for holidays and weekends.

The Exchange also believes the proposed Program is reasonable because it is designed to alleviate the migration related costs that Members would otherwise incur solely as a result of an Exchange initiated order entry protocol migration and to promote Member confidence throughout the Migration process. Absent the Program, a Member that responsibly establishes a Redundant Logical Port to preserve its access to the Exchange during a Migration would be assessed the full monthly logical port fee for a connection that, absent an Exchange Migration related issue, it would not otherwise use. By crediting such fees, the Program removes a financial disincentive to maintaining a backup connection and encourages Members to take reasonable measures to ensure continuity of access during the transition. The Exchange believes that relieving Members of these costs, which arise only because of an Exchange initiated change, supports a more orderly Migration process, reduces operational risk to Members and the market, and thereby removes impediments to and perfects the mechanism of a free and open market and a national market system, consistent with Section 6(b)(5) of the Act.

The Exchange also believes the proposed rule change is consistent with Section 6(b)(4) of the Act, which requires that Exchange rules provide for the equitable allocation of reasonable dues, fees, and other charges among its Members and other persons using its facilities. The Exchange believes the proposed Program provides for an equitable allocation of reasonable fees because the credit is available to all Members on the same terms and is governed by the same objective conditions set forth in (i) through (iv) above. Any Member that establishes a Redundant Logical Port during an ( printed page 56535) Exchange Migration, and that satisfies those conditions, is eligible for the same credit of the monthly logical port fees that would otherwise be assessed for such Redundant Logical Port. The Exchange believes it is equitable to allocate the cost of a Redundant Logical Port from Members in this limited circumstance because the underlying connection is established only in response to an Exchange initiated change and, absent an Exchange Migration related issue, is not used by the Member to enter orders and quotes into the System.

For substantially the same reasons, the Exchange believes the proposed Program is equitable and not unfairly discriminatory in accordance with Section 6(b)(5) of the Act. The Program applies uniformly to all similarly situated Members, as any Member that establishes a Redundant Logical Port in connection with an Exchange Migration and satisfies conditions (i) through (iv) is eligible for the credit on the same basis, regardless of the type or size of the Member. The credit is not available on a discretionary or selective basis; rather, it is applied according to the objective, transparent criteria set forth in the proposed rule text, following the Exchange's review of the Redundant Logical Port's order and quote usage and confirmation of the Member's compliance with those criteria. Because the availability of the credit turns solely on the objective circumstances of an Exchange Migration and the Member's compliance with uniform conditions, the Exchange believes the proposed Program does not permit unfair discrimination between customers, issuers, brokers, or dealers.

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 that is not necessary or appropriate in furtherance of the purposes of the Act. The proposed rule change does not impose any burden on intramarket competition as the Redundant Logical Port credit is available to all Members and Trading Permit Holders (“TPHs”) ^[6] on each of the EDGA's affiliated exchanges—BYX Exchange, Inc., BZX Exchange, Inc., EDGX Exchange, Inc., Cboe Exchange, Inc., and C2 Exchange, Inc. (together with EDGA, the “Affiliated Exchanges”). Additionally, as noted above, the Redundant Logical Port fee credit is uniformly to all Members and TPHs, across each of the Affiliated Exchanges, on the same terms and under the same objective conditions set forth in (i) through (iv) above. The Program applies uniformly to all similarly situated Members and TPHs, regardless of the type or size of the Member, and is not available on a discretionary or selective basis.

Although the Program relates to logical ports established in connection with an Exchange initiated order entry protocol migration, it does not favor any particular type of market participant because any Member that establishes a Redundant Logical Port during an Exchange initiated migration and satisfies conditions (i) through (iv) is eligible for the same credit. Accordingly, the Exchange believes the proposed Program is equitable and not unfairly discriminatory.

Furthermore, the proposed rule change does not impose any burden on intermarket competition. The Program is limited to fees and credits for Redundant Logical Ports that Members establish solely because of an Exchange initiated order entry protocol migration, and it does not disadvantage other exchanges. To the extent the Program makes EDGA more attractive or favorable by reducing migration-related costs and supporting continuity of Member access to the Exchange, it will help to foster competition among exchanges.

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

The Exchange neither solicited nor received comments on the proposed rule change.

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

The foregoing rule change has become effective pursuant to Section 19(b)(3)(A) of the Act ^[7] and paragraph (f) of Rule 19b-4 ^[8] thereunder. 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 will institute proceedings to determine whether the proposed rule change should be approved or disapproved.
