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 June 1, 2023. The text of the proposed rule change 
is provided in Exhibit 5.
---------------------------------------------------------------------------

    \3\ See Exchange Rule 1.5(p).
---------------------------------------------------------------------------

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 (i) modify the Liquidity Provision tiers by modifying the 
required criteria under Liquidity Provision Tier 4 and adopting a new 
Liquidity Provision Tier 6, and (ii) modify the Liquidity Removal Tiers 
by increasing the fee and modifying the required criteria under 
Liquidity Removal Tier 1 and eliminating Liquidity Removal Tier 2, as 
further described below.
    The Exchange first notes that it operates in a highly competitive 
market in which market participants can readily direct order flow to 
competing venues if they deem fee levels at a particular venue to be 
excessive or incentives to be insufficient. More specifically, the 
Exchange is only one of 16 registered equities exchanges, as well as a 
number of alternative trading systems and other off-exchange venues, to 
which market participants may direct their order flow. Based on 
publicly available information, no single registered equities exchange 
currently has more than approximately 16% of the total market share of 
executed volume of equities trading.\4\ Thus, in such a low-
concentrated and highly competitive market, no single equities exchange 
possesses significant pricing power in the execution of order flow, and 
the Exchange currently represents approximately 3.2% of the overall 
market share.\5\ The Exchange in particular operates a ``Maker-Taker'' 
model whereby it provides rebates to Members that add liquidity to the 
Exchange and charges fees to Members that remove liquidity from the 
Exchange. The Fee Schedule sets forth the standard rebates and fees 
applied per share for orders that add and remove liquidity, 
respectively. Additionally, in response to the competitive environment, 
the Exchange also offers tiered pricing, which provides Members with 
opportunities to qualify for higher rebates or lower fees where certain 
volume criteria and thresholds are met. Tiered pricing provides an 
incremental incentive for Members to strive for higher tier levels, 
which provides increasingly higher benefits or discounts for satisfying 
increasingly more stringent criteria.

    \5\ Id.
---------------------------------------------------------------------------

Liquidity Provision Tiers
    The Exchange currently provides a base rebate of $0.0018 per share 
for executions of Added Displayed Volume.\6\ The Exchange also 
currently

[[Page 38577]]

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. The Exchange now proposes to modify the Liquidity Provision Tiers 
by modifying the required criteria under such Liquidity Provision Tier 
4 and adopting a new Liquidity Provision Tier 6, as further described 
below.
---------------------------------------------------------------------------

    \6\ The base rebate for executions of Added Displayed Volume is 
referred to by the Exchange on the Fee Schedule under the existing 
description ``Added displayed volume'' with a Fee Code of ``B'', 
``D'' or ``J'', as applicable, on execution reports.
---------------------------------------------------------------------------

    First, 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 \7\ that is equal to or greater than 
0.15% of the TCV; or (2) a Displayed ADAV that is greater than or equal 
to 2,000,000 shares and a Step-Up Displayed ADAV \8\ from April 2023 
that is greater than or equal to 50% of the Member's April 2023 
Displayed ADAV.\9\ The Exchange now proposes to modify the required 
criteria under Liquidity Provision Tier 4 such that a Member would 
qualify for such tier by achieving: (1) an ADAV that is equal to or 
greater than 0.15% of the TCV; or (2) a Displayed ADAV that is equal to 
or greater than 0.02% of the TCV and a Step-Up Displayed ADAV of the 
TCV from April 2023 that is equal to or greater than 50% of the 
Member's April 2023 Displayed ADAV of the TCV. Thus, such proposed 
change would keep the existing criteria (1) intact and modify the 
alternative Displayed ADAV and a Step-Up Displayed ADAV thresholds in 
criteria (2), which are designed to encourage the submission of 
additional liquidity-adding order flow to the Exchange. Additionally, 
the Exchange is proposing that criteria (2) of Liquidity Provision Tier 
4 will expire no later than October 31, 2023, which is currently the 
case under the existing Liquidity Provision Tier 4 criteria (2). The 
Exchange is not proposing to change the rebate provided under such 
tier.
---------------------------------------------------------------------------

    \7\ As set forth on the Fee Schedule, ``ADAV'' means the average 
daily added volume calculated as the number of shares added per day, 
which is calculated on a monthly basis, and ``Displayed ADAV'' means 
ADAV with respect to displayed orders.
    \8\ As set forth on the Fee Schedule, ``Step-Up Displayed ADAV'' 
means Displayed ADAV in the relevant baseline month subtracted from 
current Displayed ADAV.
    \9\ The pricing for Liquidity Provision Tier 4 is referred to by 
the Exchange on the Fee Schedule under the existing description 
``Added displayed volume, Liquidity Provision Tier 4'' with a Fee 
Code of ``B4'', ``D4'' or ``J4'', as applicable, to be provided by 
the Exchange on the monthly invoices provided to Members.
---------------------------------------------------------------------------

    Second, the Exchange is proposing to establish a new tier under the 
Liquidity Provision Tiers, which, as proposed, would be referred to by 
the Exchange as Liquidity Provision Tier 6. Under the proposed new 
Liquidity Provision Tier 6, the Exchange would provide an enhanced 
rebate of $0.0024 per share for executions of Added Displayed Volume 
for Members that qualify for such tier by achieving a Displayed ADAV 
that is equal to or greater than 0.007% of the TCV and has a Step-Up 
Displayed ADAV of the TCV from May 2023 that is equal to or greater 
than 50% of the Member's May 2023 Displayed ADAV of the TCV.\10\ The 
Exchange proposes to provide Members that qualify for the proposed new 
Liquidity Provision Tier 6 a rebate of 0.075% of the total dollar 
volume of the transaction for executions of orders in securities priced 
below $1.00 per share that add displayed liquidity to the Exchange, 
which is the same rebate that is applicable to such executions under 
each of the existing Liquidity Provision Tiers. Additionally, the 
Exchange is proposing that Liquidity Provision Tier 6 will expire no 
later than November 30, 2023, and the Exchange will indicate this in a 
note under the Liquidity Provision Tiers pricing table on the Fee 
Schedule.
---------------------------------------------------------------------------

    \10\ The proposed pricing for new Liquidity Provision Tier 6 is 
referred to by the Exchange on the Fee Schedule under the 
description ``Added displayed volume, Liquidity Provision Tier 6'' 
with a Fee Code of ``B6'', ``D6'' or ``J6'', as applicable, to be 
provided by the Exchange on the monthly invoices provided to 
Members. The Exchange notes that because the determination of 
whether a Member qualifies for a certain pricing tier for a 
particular month will not be made until after the month-end, the 
Exchange will provide the Fee Codes otherwise applicable to such 
transactions on the execution reports provided to Members during the 
month and will only designate the Fee Codes applicable to the 
achieved pricing tier on the monthly invoices, which are provided 
after such determination has been made, as the Exchange does for its 
tier-based pricing today.
---------------------------------------------------------------------------

    The tiered pricing structure for executions of Added Displayed 
Volume under the Liquidity Provision Tiers provides an incremental 
incentive for Members to strive for higher volume thresholds to receive 
higher enhanced rebates for such executions and, as such, is intended 
to encourage Members to maintain or increase their order flow, 
primarily in the form of liquidity-adding volume, to the Exchange, 
thereby contributing to a deeper and more liquid market to the benefit 
of all Members and market participants. The Exchange believes that the 
Liquidity Provision Tiers, as modified by the proposed changes 
described above, reflect a reasonable and competitive pricing structure 
that is right-sized and consistent with the Exchange's overall pricing 
philosophy of encouraging added and/or displayed liquidity. 
Specifically, the Exchange believes that, after giving effect to the 
proposed changes described above, the rebate for executions of Added 
Displayed Volume provided under each of the Liquidity Provision Tiers 
1-6 remains commensurate with the corresponding required criteria under 
each such tier and is reasonably related to the market quality benefits 
that each such tier is designed to achieve.
Liquidity Removal Tiers
    The Exchange currently charges a standard fee of $0.0030 per share 
for executions of orders in securities priced at or above $1.00 per 
share that remove liquidity from the Exchange (such orders, ``Removed 
Volume''). The Exchange also currently offers Liquidity Removal Tiers 1 
and 2 under which qualifying Members are charged a discounted fee by 
achieving the corresponding required volume criteria for each such 
tier. The Exchange now proposes to modify the Liquidity Removal Tiers 
by increasing the fee charged for executions of Removed Volume under 
Liquidity Removal Tier 1 and modifying the required criteria under such 
tier and eliminating Liquidity Removal Tier 2, as further described 
below.
    With respect to Liquidity Removal Tier 1, the Exchange currently 
charges a discounted fee of $0.0029 per share for executions of Removed 
Volume by achieving one of the following two alternative criteria: (1) 
an ADV \11\ that is equal to or greater than 0.50% of the TCV \12\ and 
a Remove ADV \13\ that is equal to or greater than 0.30% of the TCV; or 
(2) an ADV that is equal to or greater than 1.00% of the TCV.
---------------------------------------------------------------------------

    \11\ As set forth on the Fee Schedule, ``ADV'' means average 
daily volume calculated as the number of shares added or removed, 
combined, per day, which is calculated on a monthly basis.
    \12\ As set forth on the Fee Schedule, ``TCV'' means total 
consolidated volume calculated as the volume reported by all 
exchanges and trade reporting facilities to a consolidated 
transaction reporting plan for the month for which the fees apply.
    \13\ As set forth on the Fee Schedule, ``Remove ADV'' means ADV 
with respect to orders that remove liquidity.
---------------------------------------------------------------------------

    Now, the Exchange proposes to increase the fee charged for 
executions of Removed Volume under Liquidity Removal Tier 1 to $0.00295 
per share, and to modify the required criteria such that a Member would 
now qualify for such tier by achieving one of the following two 
alternative criteria: (1) an ADV that is equal to or greater than 0.50% 
of the TCV; or (2) a Remove ADV

[[Page 38578]]

that is equal to or greater than 0.30% of the TCV.\14\ Thus, the 
proposed change to the required criteria would keep the ADV threshold 
and Remove ADV thresholds in the current criteria (1) the same, but 
rather than requiring Members to meet both thresholds as a single 
criteria, the Remove ADV threshold of 0.30% of the TCV would become an 
alternative, and the current alternative of an ADV that is equal or 
greater than 1.00% of the TCV would be eliminated. In other words, the 
existing ``and'' in criteria (1) would become an ``or'', which would 
replace the existing criteria (2). The Exchange is not proposing to 
change the fee for executions of orders in securities priced below 
$1.00 per share under such tier.
---------------------------------------------------------------------------

    \14\ The pricing for Liquidity Removal Tier 1 is referred to by 
the Exchange on the Fee Schedule under the existing description 
``Removed volume from MEMX Book, Liquidity Removal Tier 1'' with a 
Fee Code of ``R1'' to be provided by the Exchange on the monthly 
invoices provided to Members. The Exchange notes that because the 
determination of whether a Member qualifies for a certain pricing 
tier for a particular month will not be made until after the month-
end, the Exchange will provide the Fee Codes otherwise applicable to 
such transactions on the execution reports provided to Members 
during the month and will only designate the Fee Codes applicable to 
the achieved pricing tier on the monthly invoices, which are 
provided after such determination has been made, as the Exchange 
does for its tier-based pricing today.
---------------------------------------------------------------------------

    With respect to Liquidity Removal Tier 2, the Exchange currently 
charges a discounted fee of $0.00295 per share for executions of 
Removed Volume by achieving an ADV that is equal to or greater than 
0.25% of the TCV. The Exchange now proposes to eliminate Liquidity 
Removal Tier 2, as the Exchange no longer wishes to, nor is it required 
to, maintain such tier.
    The proposed changes to the Liquidity Removal Tiers are designed to 
encourage Members to maintain or increase their order flow, including 
in the form of orders that remove liquidity, to the Exchange in order 
to qualify for the proposed discounted fee for executions of Removed 
Volume. While the Exchange's overall pricing philosophy generally 
encourages adding liquidity over removing liquidity, the Exchange 
believes that providing alternative criteria that are based on 
different types of volume that Members may choose to achieve, such as 
the proposed new criteria which includes a Remove ADV threshold, 
contributes to a more robust and well-balanced market ecosystem on the 
Exchange to the benefit of all Members.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent 
with the provisions of Section 6 of the Act,\15\ in general, and with 
Sections 6(b)(4) and 6(b)(5) of the Act,\16\ 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.

---------------------------------------------------------------------------

    As discussed above, the Exchange operates in a highly fragmented 
and competitive market in which market participants can readily direct 
order flow to competing venues if they deem fee levels at a particular 
venue to be excessive or incentives to be insufficient, and the 
Exchange represents only a small percentage of the overall market. The 
Commission and the courts have repeatedly expressed their preference 
for competition over regulatory intervention in determining prices, 
products, and services in the securities markets. In Regulation NMS, 
the Commission highlighted the importance of market forces in 
determining prices and SRO revenues and also recognized that current 
regulation of the market system ``has been remarkably successful in 
promoting market competition in its broader forms that are most 
important to investors and listed companies.'' \17\

70 FR 37496, 37499 (June 29, 2005).
---------------------------------------------------------------------------

    The Exchange believes that the ever-shifting market share among the 
exchanges from month to month demonstrates that market participants can 
shift order flow or discontinue to reduce use of certain categories of 
products, in response to new or different pricing structures being 
introduced into the market. Accordingly, competitive forces constrain 
the Exchange's transaction fees and rebates, and market participants 
can readily trade on competing venues if they deem pricing levels at 
those other venues to be more favorable. The Exchange believes the 
proposal reflects a reasonable and competitive pricing structure 
designed to incentivize market participants to direct additional order 
flow, including displayed, liquidity-adding and/or liquidity-removing 
orders, to the Exchange, which the Exchange believes would promote 
price discovery and enhance liquidity and market quality on the 
Exchange to the benefit of all Members and market participants.
    The Exchange notes that volume-based incentives and discounts have 
been widely adopted by exchanges, including the Exchange, and are 
reasonable, equitable and not unfairly discriminatory because they are 
open to all members on an equal basis and provide additional benefits 
or discounts that are reasonably related to the value to an exchange's 
market quality associated with higher levels of market activity, such 
as higher levels of liquidity provision and/or growth patterns, and the 
introduction of higher volumes of orders into the price and volume 
discovery process. The Exchange believes that the Liquidity Provision 
Tier 4 as modified by the proposed change to the required criteria 
under such tier, the proposed new Liquidity Provision Tier 6, and the 
Liquidity Removal Tier 1 as modified by the proposed changes to the fee 
for executions of Removed Volume and the required criteria under such 
tier are reasonable, equitable and not unfairly discriminatory for 
these same reasons, as such tiers would provide Members with an 
incremental incentive to achieve certain volume thresholds on the 
Exchange, are available to all Members on an equal basis, and, as 
described above, are designed to encourage Members to maintain or 
increase their order flow, including in the form of displayed, 
liquidity-adding and/or liquidity removing orders, to the Exchange in 
order to qualify for an enhanced rebate for executions of Added 
Displayed Volume or a discounted fee for executions of Removed Volume, 
as applicable, thereby contributing to a deeper, more liquid and well 
balanced market ecosystem on the Exchange to the benefit of all Members 
and market participants. The Exchange also believes that such tiers 
reflect a reasonable and equitable allocation of fees and rebates, as 
the Exchange believes that the enhanced rebate for executions of Added 
Displayed Volume under the proposed modified Liquidity Provision Tier 4 
and the proposed new Liquidity Provision Tier 6, as well as the 
discounted fee for executions of Removed Volume under the modified 
Liquidity Removal Tier 1, each remains commensurate with the 
corresponding required criteria under each such tier and is reasonably 
related to the market quality benefits that each such tier is designed 
to achieve, as described above. While the Exchange has proposed 
increasing its fees for certain executions of Removed Volume, the 
Exchange believes that such change represents a modest increase from 
the current fee applicable to such executions.
    For the reasons discussed above, the Exchange submits that the 
proposal

[[Page 38579]]

satisfies the requirements of Sections 6(b)(4) and 6(b)(5) of the Act 
\18\ 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. As described more fully below 
in the Exchange's statement regarding the burden on competition, the 
Exchange believes that its transaction pricing is subject to 
significant competitive forces, and that the proposed fees and rebates 
described herein are appropriate to address such forces.
---------------------------------------------------------------------------

    \18\ 15 U.S.C. 78f(b)(4) and (5).
---------------------------------------------------------------------------

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

    The Exchange does not believe that the proposal will result in any 
burden on competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. Instead, as discussed above, 
the proposal is intended to incentivize market participants to direct 
additional order flow, including displayed, liquidity-adding and 
liquidity-removing orders, to the Exchange, thereby enhancing liquidity 
and market quality on the Exchange to the benefit of all Members and 
market participants, as well as to generate additional revenue and 
decrease the Exchange's expenditures with respect to its transaction 
pricing in a manner that is still consistent with the Exchange's 
overall pricing philosophy of encouraging added displayed liquidity. As 
a result, the Exchange believes the proposal would enhance its 
competitiveness as a market that attracts actionable orders, thereby 
making it a more desirable destination venue for its customers. For 
these reasons, the Exchange believes that the proposal furthers the 
Commission's goal in adopting Regulation NMS of fostering competition 
among orders, which promotes ``more efficient pricing of individual 
stocks for all types of orders, large and small.'' \19\
---------------------------------------------------------------------------

    \19\ See supra note 17.
---------------------------------------------------------------------------

Intramarket Competition
    As discussed above, the Exchange believes that the proposal would 
incentivize Members to submit additional order flow, including 
displayed, liquidity-adding and liquidity-removing orders, to the 
Exchange, thereby enhancing liquidity and market quality on the 
Exchange to the benefit of all Members, as well as enhancing the 
attractiveness of the Exchange as a trading venue, which the Exchange 
believes, in turn, would continue to encourage market participants to 
direct additional order flow to the Exchange. Greater liquidity 
benefits all Members by providing more trading opportunities and 
encourages Members to send additional orders to the Exchange, thereby 
contributing to robust levels of liquidity, which benefits all market 
participants. The opportunity to qualify for the proposed new Liquidity 
Provision Tier 6, and thus receive the proposed enhanced rebate for 
executions of Added Displayed Volume under such tier, would be 
available to all Members that meet the associated volume requirements 
in any month. Similarly, the opportunity to qualify for the proposed 
modified criteria under Liquidity Provision 4 and the proposed modified 
criteria under Liquidity Removal Tier 1, and thus received the enhanced 
rebate for executions of Added Displayed Volume or be charged the 
discounted fee for executions of Removed Volume, respectively, would 
continue to be available to all Members that meet the associated volume 
requirements in any month. For the foregoing reasons, the Exchange 
believes the proposed changes would not impose any burden on 
intramarket competition that is not necessary or appropriate in 
furtherance of the purposes of the Act.
Intermarket Competition
    As noted above, the Exchange operates in a highly competitive 
market in which market participants can readily direct order flow to 
competing venues if they deem fee levels at a particular venue to be 
excessive or incentives to be insufficient. Members have numerous 
alternative venues that they may participate on and direct their order 
flow to, including 15 other equities exchanges and numerous alternative 
trading systems and other off-exchange venues. As noted above, no 
single registered equities exchange currently has more than 
approximately 16% of the total market share of executed volume of 
equities trading. Thus, in such a low-concentrated and highly 
competitive market, no single equities exchange possesses significant 
pricing power in the execution of order flow. Moreover, the Exchange 
believes that the ever-shifting market share among the exchanges from 
month to month demonstrates that market participants can shift order 
flow or discontinue to reduce use of certain categories of products, in 
response to new or different pricing structures being introduced into 
the market. Accordingly, competitive forces constrain the Exchange's 
transaction fees and rebates, including with respect to Added Displayed 
Volume, and Removed Volume, and market participants can readily choose 
to send their orders to other exchange and off-exchange venues if they 
deem fee levels at those other venues to be more favorable. As 
described above, the proposed changes represent a competitive proposal 
through which the Exchange is seeking to generate additional revenue 
with respect to its transaction pricing and to encourage the submission 
of additional order flow to the Exchange through volume-based tiers, 
which have been widely adopted by exchanges, including the Exchange. 
Accordingly, the Exchange believes the proposal would not burden, but 
rather promote, intermarket competition by enabling it to better 
compete with other exchanges that offer similar pricing incentives to 
market participants.
    Additionally, the Commission has repeatedly expressed its 
preference for competition over regulatory intervention in determining 
prices, products, and services in the securities markets. Specifically, 
in Regulation NMS, the Commission highlighted the importance of market 
forces in determining prices and SRO revenues and, also, recognized 
that current regulation of the market system ``has been remarkably 
successful in promoting market competition in its broader forms that 
are most important to investors and listed companies.'' \20\ The fact 
that this market is competitive has also long been recognized by the 
courts. In NetCoalition v. SEC, the D.C. Circuit stated as follows: 
``[n]o one disputes that competition for order flow is `fierce.' . . . 
As the SEC explained, `[i]n the U.S. national market system, buyers and 
sellers of securities, and the broker-dealers that act as their order-
routing agents, have a wide range of choices of where to route orders 
for execution'; [and] `no exchange can afford to take its market share 
percentages for granted' because `no exchange possesses a monopoly, 
regulatory or otherwise, in the execution of order flow from broker 
dealers' . . . .''.\21\ Accordingly, the Exchange does not believe its 
proposed pricing changes impose any burden on competition that is not 
necessary or appropriate in furtherance of the purposes of the Act.
