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 introduce new 
language governing the fees applicable to executions in Step Up 
Mechanism auctions.
    The text of the proposed rule change is also available on the 
Commission's website (<a href="https://www.sec.gov/rules/sro.shtml">https://www.sec.gov/rules/sro.shtml</a>), the 
Exchange's website (<a href="https://www.cboe.com/us/options/regulation/rule_filings/ctwo/">https://www.cboe.com/us/options/regulation/rule_filings/ctwo/</a>), 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 amend its Fee Schedule to introduce new 
language implementing the fees applicable to executions in Step Up 
Mechanism (``SUM'') auctions.
    Currently, SUM auction fees are handled in the same manner as 
Complex Order Auctions (``COAs''). Meaning, that the incoming/auctioned 
order will receive applicable Add rates, and auction response and 
unrelated orders will receive applicable Remove rates.\3\ The Exchange 
now proposes to include additional language in its Fee Schedule stating 
that, for executions that occur within the SUM auction, the incoming 
order will receive applicable Remove rate, and the auction response and 
unrelated orders will receive the applicable Add rate.
---------------------------------------------------------------------------

    \3\ See C2 Options Fee Schedule.
---------------------------------------------------------------------------

    By way of background, the Exchange recently adopted SUM, a new 
automated order handling mechanism.\4\ SUM is a feature within the 
System that provides automated order handling in designated classes for 
qualifying orders that are not automatically executed by the System and 
is set forth in Exchange Rule 5.35.
---------------------------------------------------------------------------

    \4\ See Securities Exchange Act Release No. 106224 (August 28, 
2026), 91 FR 56514 (September 2, 2026) (SR-C2-2026-024).
---------------------------------------------------------------------------

    Under Rule 5.35(b), upon receipt of a SUM-eligible order, the 
System electronically exposes the order at the national best bid or 
offer (``NBBO'') immediately upon receipt, for a period of time 
determined by the Exchange on a class-by-class basis that may not 
exceed one second. During the exposure period, all Users may submit 
responses to the exposure message. The purpose of SUM is to provide all 
Users with the opportunity to improve their prices and ``step up'' to 
meet the NBBO in order to interact with orders sent to the Exchange. As 
the Exchange explained in its prior filing, this allows the market 
participant sending an order to the Exchange to increase its chances of 
receiving an execution at the Exchange (the market participant's chosen 
venue) instead of having the order be routed to another exchange.\5\ 
Further, SUM and the ``step up'' process enable Users to add liquidity 
that is available to interact with orders sent to the Exchange.
---------------------------------------------------------------------------

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

    In connection with the adoption of SUM,\6\ the Exchange proposes to 
implement new language for the fees applicable to volume executed 
through SUM auctions. As a general matter, the Exchange's Fee Schedule 
assesses a fee to volume that removes liquidity (a ``remove'' fee) and 
a separate fee (or, as applicable, a rebate or fee waiver) to volume 
that adds liquidity (an ``add'' fee). There is existing language in the 
Exchange's Fee Schedule for COAs: ``For executions that occur within 
the Complex Order Auction (``COA'') against auction responses, the 
incoming order will receive applicable Add rates, and auction responses 
and unrelated orders will receive applicable Remove rates.'' Currently, 
this same logic is being applied for SUM auction executions.
---------------------------------------------------------------------------

    \6\ SUM was implemented on the Exchange on September 4, 2026 
(see Reminder--Cboe C2 Options to Introduce Step-Up Mechanism (SUM) 
Auction).
---------------------------------------------------------------------------

    The Exchange proposes to add in new language for executions in SUM 
auctions by stating that incoming orders will receive the applicable 
Remove rate and auction responses and unrelated orders will receive the 
applicable Add rates. As it relates to SUM auctions, the remove fee 
would apply to the volume resulting from a primary order (i.e., the 
order that initiates the SUM auction and is exposed by the System), and 
the add fee would apply to the volume resulting from a response to SUM 
(i.e., the liquidity-providing responses submitted by Users during the 
exposure period) or an unrelated order that executes against the 
initiating order in compliance with Rule 5.35. In other words, the 
primary order that initiates a SUM auction is treated as removing 
liquidity, while a response to a SUM auction or an unrelated order that 
executes against the initiating order is treated as adding liquidity. 
The Exchange believes this treatment appropriately reflects the 
function of each side of a SUM auction: the primary order is seeking to 
access liquidity, while the response is

[[Page 60185]]

providing liquidity that steps up to interact with the primary order.
    The proposed change does not adopt any new fee and does not change 
the amount of any fee assessed under the Fee Schedule; rather, it 
implements an updated fee framework for SUM volume.
    The proposed language is similar to the existing treatment of SUM 
auctions on the Fee Schedule of the Exchange's affiliate, Cboe 
Exchange, Inc (``Cboe''). Consistent with the Cboe Fee Schedule, the 
Exchange's proposed language reflects the same principle that, in a SUM 
auction, the primary order that initiates the auction is treated as 
taker (removing) volume, and responses to the auction are treated as 
maker (adding) volume. The Cboe Fee Schedule reflects this treatment in 
Footnotes 9 and 44. As reflected in the Cboe Fee Schedule, the Taker 
fees apply to the volume resulting from a Customer's primary orders 
executed in SUM auctions, and the Maker fee waiver applies to volume 
resulting from a Customer's responses to SUM actions. The Exchange's 
proposed language is similar to the Cboe treatment for SUM auctions.
    Lastly, the Exchange notes that this fee structure does not apply 
to orders in DJX and RUT as these products have their own pricing 
tables in the C2 Fee Schedule. The Exchange notes that this same 
approach exists today for the fee structure specified above for COAs.
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.\7\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \8\ 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) \9\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers. The Exchange also believes the proposed rule 
change is consistent with Section 6(b)(4) of the Act,\10\ which 
requires that Exchange rules provide for the equitable allocation of 
reasonable dues, fees, and other charges among its Trading Permit 
Holders and other persons using its facilities.

    \9\ Id.
    \10\ 15 U.S.C. 78f(b)(4).
---------------------------------------------------------------------------

    The Exchange believes the proposed rule change is reasonable 
because it does not adopt any new fee or change the amount of any fee 
currently assessed under the Fee Schedule. Rather, the proposed 
language implements new language on how the Exchange's existing remove/
add fee framework applies to volume executed through a SUM auction--
namely, that the remove fee applies to the volume resulting from an 
incoming order that prompts a SUM auction and the add fee applies to 
the volume resulting from a response to SUM or an unrelated order 
executed as part of SUM. The Exchange believes it is reasonable to 
apply the remove fee to primary order volume and the add fee to 
response volume and unrelated orders because this treatment reflects 
the function of each side of a SUM auction, with the primary order 
accessing liquidity and the contra-side providing liquidity.
    The Exchange believes the proposed rule change is equitable and not 
unfairly discriminatory because the proposed rule change applies to all 
market participants equally. The proposed remove/add treatment of SUM 
volume applies uniformly to the primary orders and responses of all 
market participants that participate in SUM auctions. In addition, the 
Exchange believes it is equitable and not unfairly discriminatory to 
assess the remove fee for the primary order volume that removes 
liquidity and to apply the add fee to the response volume that adds 
liquidity because the Exchange wants to encourage market participation 
and price improvement. By applying the add rate to responses that step 
up to provide liquidity, the proposed rule change encourages Users to 
submit responses during the SUM exposure period, which promotes the 
competitive price-improvement dynamic that SUM is designed to foster 
and benefits investors through improved execution quality. Similarly, 
unrelated orders that execute against the order that initiates the SUM 
auction also provide liquidity and as such, receive the add rate.
    Finally, the Exchange believes the proposed rule change promotes 
just and equitable principles of trade and supports consistency in SUM 
auctions between both C2 and its affiliated exchange, Cboe. The 
proposed language is similar to the existing treatment of SUM volume on 
the Cboe Fee Schedule, as reflected in Footnotes 9 and 44. Because SUM 
on C2 is based on Cboe Options Rule 5.35, the Exchange believes it is 
appropriate and consistent with the Act for the C2 Fee Schedule to 
reflect the same remove/add treatment of SUM volume as the Cboe Fee 
Schedule. This consistency reduces potential confusion for market 
participants that trade across the Cboe affiliated exchanges and 
promotes a coherent fee framework across those affiliated markets. 
Lastly, the Exchange believes that in explicitly calling out DJX and 
RUT as inapplicable, that it provides clarity for participants as there 
are already separate fee tables in place for these products.

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 Exchange does not believe the proposed rule change will impose 
any burden on intramarket competition. The proposed language revises 
the application of the remove/add fee framework to SUM volume. This 
proposed framework applies uniformly to all market participants that 
participate in SUM auctions. The Exchange believes because the proposed 
treatment of primary orders as remove and contra-side interest as add 
reflects the economic function of each side of a SUM auction and is 
intended to encourage market participation and price improvement for 
the benefit of all market participants.
    The Exchange does not believe the proposed rule change will impose 
any burden on intermarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Act. The proposed 
rule change concerns only the revised application of the Exchange's own 
fees for volume executed on the Exchange through SUM auctions. To the 
contrary, the proposed rule change is designed to parallel the existing 
SUM fee treatment on the Exchange's affiliate, Cboe, thereby promoting 
consistency across the Cboe affiliated exchanges. Trading Permit 
Holders may readily direct their order flow to competing venues if they 
deem the Exchange's fees to be excessive. Market participants on other 
exchanges are welcome to become Trading Permit

[[Page 60186]]

Holders and trade at C2 if they determine that this proposed rule 
change has made C2 more attractive or favorable.

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 \11\ and paragraph (f) of Rule 19b-4 \12\ 
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.
