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

    In its filing with the Commission, the self-regulatory organization 
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 self-regulatory organization 
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 the 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange proposes to modify its Fee Schedule, so that starting 
on February 2, 2026,\10\ all transaction fees and rebates will be 
determinable at the time of execution, in compliance with Rule 610(d) 
of Regulation NMS.\11\ As detailed below, any transaction fees or 
rebates that are currently based upon a Member's trading or quoting 
activity in the current month will, starting in February 2026, be based 
upon that Member's trading or quoting activity in the immediately 
preceding month.\12\ Additionally, as discussed below, IEX proposes to 
offer Members two options for how the Exchange will calculate a

[[Page 738]]

Member's Incremental Fee Tier based upon the Member's trading activity 
in the prior month.
---------------------------------------------------------------------------

    \10\ See Securities Exchange Act Release No. 104172 (October 31, 
2025), 90 FR 51418 (November 17, 2025) (extending the compliance 
date for changes to Rule 610(d) to the first business day of 
February 2026, i.e. February 2, 2026).
    \11\ See 17 CFR 242.610(d) (``Transparency of fees. A national 
securities exchange shall not impose, nor permit to be imposed, any 
fee or fees, or provide, or permit to be provided, any rebate or 
other remuneration, for the execution of an order in an NMS stock 
that cannot be determined at the time of execution.'')
    \12\ All of the fee changes in this proposal relate to 
executions at or above $1.00, because, as described below, the only 
incentive fee that applies to executions priced below $1.00 is 
already determinable at the time of the execution.
---------------------------------------------------------------------------

    On September 18, 2024, the Commission adopted a final rule titled 
``Regulation NMS: Minimum Pricing Increments, Access Fees, and 
Transparency of Better Priced Orders.'' \13\ As part of the NMS 
Amendments Final Rule, the Commission amended Rule 610 to add a new 
subsection (d) ``Transparency of Fees,'' that:
---------------------------------------------------------------------------

    \13\ See Securities Exchange Act Release No. 101070 (September 
18, 2024), 89 FR 81620 (October 8, 2024) (File No. S7-30-22) (``NMS 
Amendments Final Rule'').

prohibits a national securities exchange from imposing, or 
permitting to be imposed, any fee or fees, or providing, or 
permitting to be provided, any rebate or other remuneration (e.g., 
discounted fees, other credits, or forms of linked pricing) for the 
execution of an order in an NMS stock unless such fee, rebate or 
other remuneration can be determined by the market participant at 
the time of execution. . . . any national securities exchange that 
imposes a fee or provides a rebate that is based on a certain volume 
threshold, or establishes tier requirements or tiered rates based on 
minimum volume thresholds, would be required to set such volume 
thresholds or tiers using volume achieved during a stated period 
prior to the assessment of the fee or rebate so that market 
participants are able to determine what fee or rebate level will be 
applied to any submitted order at the time of execution.'' \14\
---------------------------------------------------------------------------

    \14\ Id., 89 FR at 81663.

    The NMS Amendments Final Rule set the compliance date for the 
changes to Rule 610(d) as ``the first business day of November 2025,'' 
which was November 3, 2025.\15\ As noted above, the SEC subsequently 
extended the compliance date to February 2, 2026.\16\ Thus, IEX is now 
proposing to modify its Fee Schedule so that it will comply with Rule 
610(d) of Regulation NMS, as amended, as of February 2, 2026.
---------------------------------------------------------------------------

    \15\ See NMS Amendments Final Rule, supra note 13, 89 FR at 
81680. At the request of other national securities exchanges, the 
Commission stayed the compliance dates of parts of the NMS 
Amendments Final Rule, however the Commission did not stay the 
effective date of the changes to Reg NMS Rule 610(d), finding ``no 
reason to delay the benefits to investors, including the additional 
certainty, transparency, and clarity of the exchange fee schedules, 
of [ ] amendments to Rule 610(d).'' See In the Matter of the Motion 
by Nasdaq, Inc., et al., Securities Exchange Act Release No. 101899, 
File No. S7-30-22, at *2 (December 12, 2024) (Order Granting Partial 
Stay).
    \16\ See supra note 10.
---------------------------------------------------------------------------

    As reflected in the Transaction Fees section of the Fee Schedule, 
IEX currently uses volume-based pricing structures (both rebates and 
fees) (collectively ``Fee Tiers'') that are designed to improve market 
quality on the Exchange by incentivizing Members to send more displayed 
and non-displayed liquidity adding and removing orders to the Exchange. 
Several of IEX's Fee Tiers use a Member's ``Average Daily Volume'' 
(``ADV'') as the primary criteria for evaluating eligibility for the 
volume-based fees or rebates. The Fee Schedule defines ADV as ``average 
daily volume calculated as the number of shares added or removed (as 
applicable) that execute at or above $1.00 per share, per day. ADV is 
calculated on a monthly basis.'' \17\ In calculating a Member's ADV, 
the numerator is the share volume of applicable transactions (i.e., 
adding, removing, displayed, non-displayed, as applicable) during the 
month for which the fee or rebate tier applies. Similarly, the 
denominator of a Member's ADV is the total number of eligible trading 
days in the month for which the fee or rebate tier applies. 
Accordingly, the rebate or fee tiers in the Fee Schedule are currently 
determined by the Member's ADV during the same month for which the fees 
or rebates apply.
---------------------------------------------------------------------------

    \17\ See IEX Fee Schedule, Transaction Fees, Definitions.
---------------------------------------------------------------------------

    To comply with the Rule 610(d) of Regulation NMS, as amended, IEX 
is proposing to modify the definition of ADV in its fee schedule to 
state that the ADV is calculated ``on a monthly basis, based on trading 
activity in the immediately preceding month, unless otherwise indicated 
in the Fee Schedule.'' \18\ Consistent with that change, where 
appropriate, IEX proposes to modify any references to ADV calculations 
in the Fee Schedule that are in the present tense to instead be in the 
past tense (e.g., instead of saying ``Member: (1) adds at least 
30,000,000 ADV of displayed liquidity; or (2) adds at least 25,000,000 
ADV of displayed liquidity and trades at least 30,000,000 non-displayed 
ADV'' to qualify for Displayed Liquidity Adding Rebate Tier 7, the Fee 
Schedule would now say ``Member: (1) added at least 30,000,000 ADV of 
displayed liquidity; or (2) added at least 25,000,000 ADV of displayed 
liquidity and traded at least 30,000,000 non-displayed ADV'').
---------------------------------------------------------------------------

    \18\ As discussed below, the base fee rates will apply to new 
members during their first month of membership as no prior month 
activity will be available as the basis for volume-based fees or 
rebates.
---------------------------------------------------------------------------

    IEX notes that several of its current transaction fees, including 
some rebates, will remain unchanged by this fee filing because they are 
already determinable at the time of execution. For example, executions 
below $1.00 per share (``sub-dollar trades'') that add displayed volume 
receive a rebate of 0.15% of the Total Dollar Value (``TDV'') of the 
trade. Because the TDV is known at the time of the execution, the 
rebate is also determinable at the time of the execution. For example, 
an execution of a displayed order to sell 1,000 shares of a security 
for $0.50 per share has a total dollar value of $500, and will earn a 
rebate of $0.75 cents for the transaction.
    The IEX fees and rebates affected by this fee filing \19\ fall into 
three categories: (1) the Displayed Liquidity Adding Rebate Tiers; (2) 
the Displayed Liquidity Removing Fee Tiers; and (3) the Incremental Fee 
Tiers.
---------------------------------------------------------------------------

    \19\ The Exchange also offers incentive payments for quoting 
activity in certain securities through the Supplemental Market 
Quality Program (``SMQ''). The SMQ--which is distinct from the ETP 
quoting activity contained in the Displayed Liquidity Adding Rebate 
Tiers, described in more detail below--is unaffected by amended Rule 
610(d) because the SMQ payments are based on quoting activity rather 
than on volume of executions achieved during a certain time period, 
and have no effect on transaction fees or rebates. See Rule 610(d) 
of Reg NMS (describing its applicability to fees, rebates, or other 
remuneration ``for the execution of an order in an NMS stock''); see 
also Fee Schedule, Transaction Fees--Supplemental Market Quality 
Program.
---------------------------------------------------------------------------

Displayed Liquidity Adding Rebate Tiers 20
---------------------------------------------------------------------------

    \20\ See Fee Schedule, Transaction Fees, Fee Code Combinations 
and Associated Fees, fn. 4.
---------------------------------------------------------------------------

    There are three general ways in which a Member can qualify for one 
or more of IEX's Displayed Liquidity Adding Rebate Tiers: (1) through 
displayed liquidity adding executions; (2) through non-displayed 
executions (adding and removing), and (3) by satisfying quoting 
requirements in a minimum amount of ETPs. To the extent these tiers are 
based on volume-based transaction activity or quoting activity, the 
Exchange's proposed changes would make the reference period used to 
determine eligibility the immediately preceding month. The impact of 
the proposed changes in this filing on the Displayed Liquidity Adding 
Rebate Tiers is discussed below.
Displayed Liquidity Adding Executions
    Using Displayed Liquidity Adding Rebate Tier 7 as an example, under 
the proposed changes, if a Member either: (1) added at least 30,000,000 
ADV of displayed liquidity or (2) added at least 25,000,000 ADV of 
displayed liquidity and traded at least 30,000,000 non-displayed ADV in 
January 2026, at the end of January 2026 that Member will know that it 
has qualified for Tier 7 in both January and February 2026.\21\

[[Page 739]]

Thus, before the start of February, the Member will know that any 
displayed liquidity adding trades made on IEX in February 2026 would 
receive the applicable rebate of $0.0022 per share. If that same Member 
had 29,000,000 ADV of displayed liquidity adding trades in the month of 
February 2026, at the end of February the Member would know that it had 
qualified for Displayed Liquidity Adding Rebate Tier 6 for the month of 
March 2026, because Tier 6 has as one of its eligibility criteria that 
the Member added at least 20,000,000 ADV of displayed liquidity and 
less than 30,000,000 ADV of displayed liquidity. Thus, at the end of 
February, the Member would know that it would be eligible to receive 
the applicable rebate of $0.0020 per share for any displayed liquidity 
adding trades in March.
---------------------------------------------------------------------------

    \21\ On September 30, 2025, and October 31, 2025, IEX informed 
its Members, via two Trading Alerts, of IEX's general plans for 
compliance with amended Reg NMS Rule 610(d)'s fee determinism 
requirement. See Trading Alert #2025-031, available at https://iextrading.com/alerts/#/316 and Trading Alert #2025-032, available 
at https://iextrading.com/alerts/#/317. And IEX will send a Trading 
Alert to all Members providing more detail about these pending 
changes to its Fee Schedule in advance of the February 2, 2026, 
implementation date of these fees.
---------------------------------------------------------------------------

Non-Displayed Executions
    Displayed Liquidity Adding Rebate Tiers 2, 3, 5, 6, and 7 all have 
eligibility criteria related to a Member's ``non-displayed ADV.'' \22\ 
For example, a Member that trades at least 15,000,000 non-displayed ADV 
qualifies for Displayed Liquidity Adding Rebate Tier 5 (if the Member 
traded at least 20,000,000 non-displayed ADV, the Member would qualify 
for the next higher rebate tier, Displayed Liquidity Adding Rebate Tier 
6). Thus, currently if a Member had 16,000,000 non-displayed ADV in the 
month of January 2026, that Member would qualify for Displayed 
Liquidity Adding Rebate Tier 5 and receive a rebate of $0.0018 per 
share on all of its displayed liquidity adding trades in the month of 
January 2026.
---------------------------------------------------------------------------

    \22\ As set forth in the Fee Schedule, ``non-displayed ADV'' 
refers to executions with the following Fee Code Combinations: MI, 
MIB, TI, TIB, TIY, TIYB, TIR, TLW, TLWB, and MIA.
---------------------------------------------------------------------------

    Under this proposed fee change, at the end of January, the Member 
would know that it qualified for Displayed Liquidity Adding Rebate Tier 
5 for the month of February 2026 based upon its non-displayed execution 
activity in January 2026, and again the Member would receive a rebate 
of $0.0018 per share on all of its displayed liquidity adding trades in 
the month of February 2026.
ETP Quoting
    Displayed Liquidity Adding Rebate Tiers 3 and 4 also have 
eligibility criteria related to the Member's quoting activity in ETPs. 
Specifically, a Member may qualify for Displayed Liquidity Adding 
Rebate Tier 3 if its ``NBBO Time'' \23\ is at least 50% in at least 250 
ETPs and may qualify for Displayed Liquidity Adding Rebate Tier 4 if 
its NBBO Time is at least 50% in at least 750 ETPs.
---------------------------------------------------------------------------

    \23\ The Fee Schedule defines ``NBBO Time'' as the Member's 
``Percent Time at NBB'' plus the Member's ``Percent Time at NBO.'' 
``Percent Time at NBB (NBO)'' is defined as the aggregate of the 
percentage of time during Regular Market Hours where a Member has a 
displayed order of at least one round lot at the NBB (NBO). For 
example, for a particular security, if a Member's Percent Time at 
NBB is 25% and Percent Time at NBO is 15%, its NBBO Time would be 
40%. Alternatively, if a Member's Percent Time at NBB is 20% and 
concurrently, the Member's Percent Time at NBO is also 20%, then 
that Member's NBBO Time would be 40%.
---------------------------------------------------------------------------

    Currently, for the month of January 2026, a Member with an NBBO 
Time of at least 50% in at least 250 (but less than 750) ETPs would 
qualify for Displayed Liquidity Adding Rebate Tier 3 and receive a 
rebate of $0.0014 per share for all displayed liquidity adding 
executions priced at or above $1.00.
    Because amended Rule 610(d) requires that transaction fees and 
rebates must be determinable at the time of the execution, IEX proposes 
to modify the definitions of Percent Time at NBB, Percent Time at NBO, 
and NBBO Time to reflect that when these terms are applied to any 
transaction fees or rebates, they will be calculated using the Member's 
quoting activity for the immediately preceding month.\24\
---------------------------------------------------------------------------

    \24\ IEX also proposes to amend the definitions of these terms 
to clarify that these terms continue to refer to quoting activity 
for the current month when they are applied to the SMQ Program, an 
incentive payment for quoting in certain stocks that has no effect 
on transaction fees and rebates. See supra note 19.
---------------------------------------------------------------------------

    Thus, as proposed, the above Member with an NBBO Time of at least 
50% in at least 250 (but less than 750) ETPs in the month of January 
2026 would know, at the end of October [sic], that it had qualified for 
Displayed Liquidity Adding Rebate Tier 3 for the month of February 
2026, and would receive a rebate of $0.0014 per share for all displayed 
liquidity adding executions priced at or above $1.00 during February 
2026. If that Member had an NBBO Time of at least 50% in at least 750 
ETPs in the month of February 2026, the Member would know, at the end 
of February, that it had qualified for Displayed Liquidity Adding 
Rebate Tier 4 for the month of March 2026, and receive a rebate of 
$0.0016 per share for all displayed liquidity adding executions during 
March 2026.
Displayed Liquidity Removing Fee Tiers
    IEX also has two fee tiers for Displayed Liquidity Removing orders. 
Currently, a Member that adds less than 25,000 ADV of displayed 
liquidity pays a fee of $0.0030 for all displayed liquidity removing 
orders, while a Member that adds at least 25,000 ADV of displayed 
liquidity pays a fee of $0.0022 for all displayed liquidity removing 
executions.
    Thus, a Member that adds less than 25,000 ADV of displayed 
liquidity in January 2026 will be charged $0.0030 per share for all 
executions that remove displayed liquidity. Under this proposed fee 
change, at the end of January 2026 that same Member will know that it 
will be charged $0.0030 per share for all executions that remove 
displayed liquidity in the month of February 2026, based on its January 
displayed liquidity adding orders. Similarly, under the proposed fee 
change, if the Member adds at least 25,000 ADV of displayed liquidity 
in the month of February 2026, then at the end of the month it will 
know that it will be charged $0.0022 per share for all displayed 
liquidity removing executions in the next month, March 2026.
Incremental Fee Tiers
    IEX's Incremental Fee Tiers \25\ are a volume-based fee incentive 
designed to incentivize Members to increase their non-displayed volume 
on the Exchange. Currently, Members who increase their non-displayed 
volume from August 2025 (``the Baseline Month'' \26\) by at least 
10,000,000 non-displayed shares per day qualify for a reduced fee of 
$0.0001 per share for certain executions of non-displayed orders.\27\ 
Specifically, to qualify for the reduced fee (i.e., Incremental Fee 
Tier 2), a Member must have an ``Incremental non-displayed ADV'' \28\ 
that is at least 10,000,000 greater than its ``Baseline non-displayed 
ADV.'' \29\ Once a Member's Incremental non-displayed ADV is at least 
10,000,000 greater than its Baseline non-displayed ADV, the Member is 
charged

[[Page 740]]

the reduced fee of $0.0001 per share for the applicable non-displayed 
executions.
---------------------------------------------------------------------------

    \25\ See Footnote 6 to the Transaction Fees section of the Fee 
Schedule.
    \26\ As noted in the Fee Schedule, the criteria to qualify for 
the Incremental Fee Tier will expire no later than February 28, 
2026.
    \27\ The fee codes to which the Incremental Fee Tiers apply are 
``MI'' (Adds non-displayed liquidity); ``MIB'' (Adds non-displayed 
liquidity in Tape B securities); ``TIY'' (Post Only order removes 
non-displayed liquidity); ``TIYB'' (Post Only order removes non-
displayed liquidity in Tape B securities); ``TI'' (Removes non-
displayed liquidity); and ``TIB'' (Removes non-displayed liquidity 
in Tape B securities).
    \28\ ``Incremental non-displayed ADV'' means executions with any 
of the Fee Code Combinations MI, MIB, TI, TIB, TIY, or TIYB that 
exceed the Baseline non-displayed ADV.
    \29\ ``Baseline non-displayed ADV'' means executions with any of 
the Fee Code Combinations MI, MIB, TI, TIB, TIY, or TIYB in August 
2025.
---------------------------------------------------------------------------

    The reduced fee of $0.0001 per share for Incremental Fee eligible 
ADV in excess of the Baseline non-displayed ADV is capped at a Member's 
Baseline non-displayed ADV, and any additional volume is charged the 
regular fee of $0.0010 per share for either adding or removing non-
displayed liquidity.
    By way of example, currently if a Member's Baseline non-displayed 
ADV is 20,000,000, and its Incremental Fee eligible ADV \30\ for 
January 2026 is 30,000,000, then the Member's Incremental non-displayed 
ADV would be 10,000,000 for January 2026. For that month, the Member 
would pay the reduced $0.0001 fee for 10,000,000 of its Incremental Fee 
eligible executions and would pay the regular fee of $0.0010 for 
20,000,000 of its Incremental Fee eligible executions. If the Member's 
Incremental Fee eligible ADV for January 2026 was 40,000,000, then the 
Member's Incremental non-displayed ADV would be 20,000,000 for January 
2026. For that month, the Member would pay the reduced $0.0001 fee for 
20,000,000 of its Incremental Fee eligible executions and would pay the 
regular fee of $0.0010 for 20,000,000 of its Incremental Fee eligible 
executions.
---------------------------------------------------------------------------

    \30\ IEX proposes to introduce a new defined term, ``Incremental 
Fee eligible ADV'' to the Definitions subsection of the Transaction 
Fees section of the IEX Fee Schedule. IEX proposes to define the 
term as ``executions with any of the Fee Code Combinations MI, MIB, 
TI, TIB, TIY, or TIYB.'' IEX also proposes to modify the definition 
of ``Baseline non-displayed ADV'' to replace ``executions with any 
of the Fee Code Combinations MI, MIB, TI, TIB, TIY, or TIYB'' with 
``executions of Incremental Fee eligible ADV.''
---------------------------------------------------------------------------

    IEX proposes to modify the definition of Incremental non-displayed 
ADV so that starting on February 2, 2026, it will refer to ``executions 
in the immediately preceding month of Incremental Fee eligible ADV that 
exceed the Baseline non-displayed ADV'' (emphasis added). Thus, 
starting with the month of February, Members will know that they 
qualified for Incremental Fee Tier 2 in that month if they exceeded 
their Baseline non-displayed ADV by at least 10,000,000 in the 
immediately preceding month.
    Referring to the same example above, at the end of January, the 
Member would know that for February 2026, the Member qualified for 
Incremental Fee Tier 2 based upon its January trading activity. As 
described above, starting in February 2026, Members will need to be 
able to determine the fees charged for an execution at the time of the 
execution. To satisfy the requirements of Rule 610(d) of Regulation 
NMS, and as noted above, IEX proposes to offer Members two options for 
how the Exchange will charge for Incremental Fee eligible executions 
for a given month, both of which will allow Members to determine the 
fees at the time of applicable executions.

Proposed Changes

A. Explanatory Bullets

    IEX proposes to add the following explanatory bullets to the 
beginning of the Incremental Fee Tiers section of the Fee Schedule 
(above the existing table listing the two Incremental Fee Tiers):
     IEX's Incremental Fee Tiers provide Members an opportunity 
to pay a reduced fee of $0.0001 per share (the ``Incremental Fee'') for 
Incremental Fee eligible ADV in the current month.
    [cir] A Member qualifies for the Incremental Fee (i.e., Incremental 
Fee Tier 2) in the current month if its Incremental non-displayed ADV 
exceeded its Baseline non-displayed ADV by at least 10,000,000.
    [cir] Incremental Fee eligible ADV that does not qualify for 
Incremental Fee Tier 2 is charged the base rate of $0.0010 per share.
    [cir] The current month's Incremental Fee eligible ADV will 
determine the Member's qualification for Incremental Fee Tier 2 for the 
next month.
     IEX offers Members two options for calculating trading 
fees for the Incremental Fee Tier, each of which achieves fee 
determinism.
    [cir] Members shall notify IEX of which Incremental Fee option the 
Member wants applied to its Incremental Fee eligible ADV, in such 
manner as specified by the Exchange, in advance of the beginning of a 
new calendar month. If the Member does not select an option (and has 
not previously selected an option), the default option for calculating 
the Member's Incremental Fee will be Option 1.
    These bullets provide an overview of the two Incremental Fee 
options and inform Members that they can qualify for Incremental Fee 
Tier 2 in the current month if their Incremental non-displayed ADV in 
the prior month exceeded their Baseline non-displayed ADV by at least 
10,000,000. Additionally, the explanatory bullets note that Incremental 
Fee eligible ADV that does not qualify for Incremental Fee Tier 2 is 
charged the base rate of $0.0010 per share.

B. Changes to Incremental Fee Tier Table

    IEX also proposes to make the following changes to the Incremental 
Fee Tier table:
     Add as a title for the table: ``Incremental Fee Tier Fee 
Calculation Table (used by both Options 1 and 2)'';
     Revise the language in the ``Required Criteria'' cells to 
change ``is'' to ``was'', because Incremental non-displayed ADV has 
been redefined to be based on the prior month's activity;
     Remove the second and third sentences in ``footnote a'' to 
the table, because they no longer reflect the manner in which 
Incremental Fees are calculated.

C. Option 1

    Under Option 1, a Member's Incremental Fee eligible ADV in the 
current month will incur a fee representing a blended average rate of 
their fee-eligible activity in the prior month (starting in February 
2026).\31\
---------------------------------------------------------------------------

    \31\ For example, if a Member's Baseline non-displayed ADV is 
20,000,000, and its Incremental Fee eligible ADV for January 2026 is 
30,000,000 (i.e., an Incremental non-displayed ADV of 10,000,000), 
the Member's blended rate for February would be $0.0007 per share 
(because 20,000,000 would be charged $0.0010 and 10,000,000 would be 
charged $0.0001).
---------------------------------------------------------------------------

    To effect these changes, IEX proposes to add a section describing 
``Incremental Fee Tier Option 1'' immediately following the Incremental 
Fee Tier Calculation Table. Under the section header, IEX proposes to 
add the following text:
     For Option 1, IEX will apply the Incremental Fee Tier 
Calculation Table to the Member's Incremental Fee eligible ADV in the 
prior month to calculate the blended rate based on the fees charged to 
the Member for its prior month activity (rounded to five decimal 
places). The blended rate will be applied to all Incremental Fee 
eligible ADV in the current month.
     The following examples demonstrate how this fee is 
determinable at the time of execution (in the examples, millions are 
abbreviated as ``mm'', e.g., ``20,000,000'' is written as ``20mm''):
    In order to demonstrate how the fee works, IEX proposes to include 
this set of examples, with three explanatory footnotes, under the text 
described above:

\*\ Incremental Fee eligible ADV.
** A Member with a Baseline non-displayed ADV of 20,000,000 that has Incremental Fee eligible ADV of 30,000,000
  in January will pay $0.0007 for all Incremental Fee eligible ADV in both January and February, because that is
  the blended average of the Member's January trading fees ($0.0010/share fee for 20,000,000 and $0.0001/share
  fee for 10,000,000).
*** A Member with a Baseline non-displayed ADV of 20,000,000 that has an Incremental Fee eligible ADV of
  30,000,000 in January and 35,000,000 in February will pay $0.00061 for all Incremental Fee eligible ADV in
  March, because that is the blended average of the Member's February trading fees ($0.0010/share fee for
  20,000,000 and $0.0001/share fee for 15,000,000). Since the prior month's blended rate is used, the fact that
  the Member's March 2026 volumes did not exceed the baseline would not be taken into account until April 2026
  billing.

D. Option 2

    Under proposed Option 2, Incremental Fees are calculated based on 
total shares traded in the current month, not a blended rate of the 
prior month's Incremental Fee eligible ADV (like in Option 1). Thus, 
Option 2 introduces the following terms:
    [cir] ``Baseline non-displayed TAV'' is calculated by multiplying 
the Baseline non-displayed ADV times the number of trading days in the 
current month.
    [cir] ``Incremental Fee eligible TAV'' is calculated by multiplying 
the current month's Incremental Fee eligible ADV times the number of 
trading days in the current month.
    [cir] ``Incremental non-displayed TAV'' is the amount by which the 
current month's Incremental Fee eligible TAV exceeds the Baseline non-
displayed TAV. If the Baseline non-displayed TAV is greater than the 
Incremental Fee eligible TAV, this value is 0. If this value exceeds 
the Baseline non-displayed TAV, the number of shares eligible for the 
reduced Incremental Fee is capped at Baseline non-displayed TAV.
    In order to demonstrate how Option 2 works and how the fee is 
determinable at the time of execution, IEX proposes to include in the 
Fee Schedule this set of examples under the text described above, and 
text explaining that in the examples, millions are abbreviated as 
``mm'', e.g., ``20,000,000'' is written as ``20mm'':

    As shown in the above examples, the fees for Incremental Fee 
eligible executions under Option 2 will change during the month in 
which they are billed, but in a manner in which the fees for any 
executions are determinable at the time of the execution. IEX 
introduced the Incremental Fee Tiers in September 2025,\32\ and based 
upon the past several months of trading activity, believes that its 
Members' trading systems are be able to accommodate such pricing, 
recognizing when their Incremental Fee eligible executions have crossed 
the first threshold that qualifies the next executions for the $0.0001 
per share discounted fee, as well as if they reached the cap on the 
executions eligible for the discounted fee, meaning any additional 
Incremental Fee eligible executions for that month will be charged 
$0.0010 per share. Additionally, upon request, IEX will provide a tally 
of month-to-date executions to any Member that qualified for the 
Incremental Fee based upon its prior month activity, in order to 
facilitate the Member's ability to know the fee charged at the time of 
execution. Further, IEX will continue to bill Members at the end of the 
month, and the total amount billed will reflect this pricing.
---------------------------------------------------------------------------

    \32\ See Trading Alert # 2025-024, available at https://iextrading.com/alerts/#/308.
---------------------------------------------------------------------------

    The Exchange is not proposing to change the amounts of any rebates 
or fees specified in the transaction fee tiers, nor the fees applicable 
to executions below $1.00 per share. The Exchange is also not proposing 
to make any changes to the fees applicable to the execution of Retail 
orders that add or remove displayed or non-displayed liquidity.
    The Exchange plans to implement the proposed fee change on February 
2, 2026, subject to the filing and effectiveness of this proposed rule 
change.
2. Statutory Basis
    IEX believes that the proposed rule change is consistent with the 
provisions of Section 6(b) \33\ of the Act in general, and furthers the 
objectives of Section 6(b)(4) \34\ of the Act, in particular, in that 
it is designed to provide for the equitable allocation of reasonable 
dues, fees and other charges among its Members and other persons using 
its facilities. The Exchange believes that the proposed fee change is 
reasonable, fair and equitable, and non-discriminatory.
---------------------------------------------------------------------------

    \33\ 15 U.S.C. 78f.
    \34\ 15 U.S.C. 78f(b)(4).
---------------------------------------------------------------------------

    As described in the Purpose section, all of these proposed fee 
changes are being made in response to the amendments to Rule 610(d) of 
Regulation NMS, which the Commission has determined have a compliance 
date of February 2, 2026. As noted by the Commission in the NMS 
Amendments Final Rule, these proposed fee changes are designed to make 
the Exchange's transaction fees and rebates determinable at the time of 
the execution and thereby protect investors through more fee 
transparency, as required by the Act.
    Further, IEX believes that the proposed introduction of two options 
for applying the Incremental Fee in a deterministic manner is 
consistent with Rule 610(d) of Regulation NMS, as well as the 
provisions of Section 6(b) \35\ of the Act in general, and furthers the 
objectives of Section6(b)(4) \36\ of the Act, in particular, in that it 
is designed to provide for the equitable allocation of reasonable dues, 
fees and other charges among its Members and other persons using its 
facilities. First, as discussed in the Purpose section, Members 
applying either option will be able to determine the fee for any 
executions at the time of the execution. Second, the Exchange 
understands that different firms, using different trading strategies, 
might prefer one of the Incremental Fee options over the other. And 
third, Members will always be free to change the Incremental Fee option 
applied to their Incremental Fee eligible executions before the 
beginning of trading in the next month. For these reasons, the Exchange 
believes that the proposed fee change is reasonable, fair and 
equitable, and non-discriminatory. Additionally, IEX believes that 
setting a fixed decimal point to which blended rate fees will be 
rounded, and communicating that decimal point to Members, is consistent 
with the Act in that it supports each Member's ability to determine the 
exact fee charged for any execution at the time of the transaction. 
This transparency around how the average blended rates will be applied 
to a Member's activity will allow Members to more precisely calculate 
their blended rate fees, thereby ensuring equitable allocation of fees 
while reducing the potential for confusion about the fees that IEX will 
charge under Incremental Fee Tier Option 1.

    \36\ 15 U.S.C. 78f(b)(4).
---------------------------------------------------------------------------

    Accordingly, IEX has designed the proposed changes to its Fee 
Schedule to allow for a continued transparent and equitable 
distribution of its fees that is consistent with the goals and 
requirements of the NMS Amendments Final Rule. IEX notes that all other 
national securities exchanges that offer transaction fee incentives 
based upon a Member's trading or quoting activity will be similarly 
changing their fee schedules to comply with the February 2, 2026 
compliance deadline.
    As discussed above, IEX does not believe that any aspect of this 
proposal raises new or novel issues not already considered by the 
Commission.

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

    IEX does not believe that the proposed rule change will result in 
any burden on competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. Because these changes are being 
made in response to a regulatory requirement set forth by the 
Commission, these changes are not designed to serve any competitive 
purpose, let alone create any burden on competition. Rather, they are 
designed to ensure that the Commission's requirements for exchange 
transaction fees apply on the Exchange just as they do on any other 
national securities exchange. Thus, the Exchange does not believe that 
the proposed rule change will impose any burden on intermarket 
competition, let alone a burden on intermarket competition that is not 
necessary or appropriate in furtherance of the purposes of the Act. 
Moreover, as noted in the Statutory Basis section, the Exchange does 
not believe that the proposed changes raise any new or novel issues not 
already considered by the Commission.
    The Exchange does not believe that the proposed rule change will 
impose any burden on intramarket competition because these changes are 
being made in response to a Commission rule and will apply equally to 
all Members of the Exchange.
    The Exchange further notes that the proposed rule change is 
designed to align the Exchange's Fee Schedule with amended Rule 610(d) 
by providing certainty as to the Exchange's transaction fees at the 
time of execution. The Exchange also notes that all Industry Members 
that offer tiered fees and rebates based on trading volume in NMS 
Securities will be required to comply with amended Rule 610(d). To the 
extent that competing exchanges are proposing or will propose similar 
amendments to their Fee Schedules, this proposed rule change does not 
impose a burden on competition.
