          - [Release No. 34-99266; File No. SR-MEMX-2023-41]

                    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 December 26, 2023, MEMX LLC (“MEMX” or the “Exchange”) 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 is filing with the Commission a proposed rule change to amend the Exchange's fee schedule applicable to Members [3]                                          (the “Fee Schedule”) pursuant to Exchange Rules 15.1(a) and (c). The Exchange proposes to implement the changes to the Fee Schedule pursuant to this proposal on January 1, 2024. The text of the proposed rule change is provided in Exhibit 5.                

## 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 amend the Fee Schedule to remove an expired criteria under Liquidity Provision Tier 4.

                    The Exchange currently provides a base rebate of $0.0015 per share for executions of orders in securities priced at or above $1.00 per share that add displayed liquidity to the Exchange (such orders, “Added Displayed Volume”).[4]                                          The Exchange also currently offers Liquidity Provision Tiers 1-5 under which a Member may receive an enhanced rebate for executions of Added Displayed Volume by achieving the corresponding required volume criteria for each such tier. With respect to Liquidity Provision Tier 4, the Exchange currently provides an enhanced rebate of $0.0029 per share for executions of Added Displayed Volume for Members that qualify for such tier by achieving: (1) an ADAV [5]                                          (excluding Retail Orders) that is equal to or greater than 0.09% of the TCV; [6]                                          or (2) an ADAV that is equal to or greater than 0.006% of the TCV and a Step-Up                           ( print page 1133)                        ADAV [7]                                          from June 2023 that is equal to or greater than 40% of the Member's June 2023 ADAV.[8]                                          Additionally, the Fee Schedule indicates that criteria (2) of Liquidity Provision Tier 4 will expire no later than December 31, 2023. Now, given the expiration of criteria (2) of Liquidity Provision Tier 4, it is necessary to modify the Fee Schedule to delete this criteria (2) as well as the note under the Liquidity Provision Tiers pricing table that indicates its expiration, as both are no longer applicable and otherwise obsolete. The Exchange is not proposing to make any changes to this or any other Liquidity Provision Tier, and as such, Liquidity Provision Tier 4 will now consist solely of the previously existing criteria (1).                

#### 2. Statutory Basis

                    The Exchange believes that the proposed rule change is consistent with the provisions of Section 6 of the Act,[9]                                          in general, and with Sections 6(b)(4) and 6(b)(5) of the Act,[10]                                          in particular, in that it provides for the equitable allocation of reasonable dues, fees and other charges among its Members and other persons using its facilities and is not designed to permit unfair discrimination between customers, issuers, brokers, or dealers.                

The Exchange believes that the proposed change to modify Liquidity Provision Tier 4 to remove the expired criteria (2) criteria is reasonable because there was an expiration date associated with this criteria that has now passed. As such, this criteria is no longer available under this tier, and should not remain on the Fee Schedule. The Exchange believes that the enhanced rebate for executions of Added Displayed Volume provided under Liquidity Provision Tier 4, which the Exchange is not proposing to change with this proposal, remains commensurate with the required criteria under such tier, as modified, and is reasonably related to the market quality benefits that such tier is designed to achieve. The Exchange also believes the enhanced rebate for executions of Added Displayed Volume provided under Liquidity Provision Tier 4 remains equitable and not unfairly discriminatory, as such enhanced rebate will continue to apply equally to all qualifying Members.

                    For the reasons discussed above, the Exchange submits that the proposal satisfies the requirements of Sections 6(b)(4) and 6(b)(5) of the Act [11]                                          in that it provides for the equitable allocation of reasonable dues, fees and other charges among its Members and other persons using its facilities and is not designed to unfairly discriminate between customers, issuers, brokers, or dealers.                

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

                    In accordance with Section 6(b)(8) of the Act,[12]                                          the Exchange believes that the proposed rule change will not impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.                

The Exchange believes that the proposed rule change would not place any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. The proposed rule change is not designed to address any competitive issues but rather is designed to enhance the clarity of the Fee Schedule and alleviate possible Member confusion that may arise from the inclusion of obsolete language.

### 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)(ii) of the Act [13]                                          and Rule 19b-4(f)(2) [14]                                          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 shall institute proceedings to determine whether the proposed rule change should be approved or disapproved.
