sections A, B, and C below, of the most significant aspects of such 
statements.

[[Page 55657]]

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

1. Purpose
    The Exchange proposes to delay the implementation of SR-ISE-2026-18 
which amended Supplementary Material .01 and .03 to Options 3, Section 
11 (Auction Mechanisms), Supplementary Material .06 to Options 3, 
Section 13 (Price Improvement Mechanism for Crossing Transactions), 
Options 3A, Section 12 (FLEX Price Improvement Mechanism (``FLEX PIM'' 
or ``FLEX PIM Auction''), and Supplementary Material .02 to Options 3A, 
Section 13 (FLEX Solicited Order Mechanism (``FLEX SOM'' or ``FLEX SOM 
Auction'') to permit orders by Members in a Facilitation Mechanism, a 
SOM, a PIM, a FLEX PIM or a FLEX SOM to trade against Agency Orders for 
the accounts of Market Makers assigned to the options class.
    SR-ISE-2026-18 stated that the Exchange would implement the 
proposed changes on or before Q3 2026, and that it would issue an 
Options Trader Alert indicating the date the changes will be 
implemented. The Exchange now proposes to amend the implementation date 
to on or before November 10, 2026 to provide additional time to 
complete implementation of the changes. The Exchange requires a few 
additional weeks to complete the technology development and testing. 
The Exchange will issue an Options Trader Alert to Members announcing 
the specific implementation date in advance of implementation.
    The Exchange does not propose any substantive changes to SR-ISE-
2026-18.
2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\4\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\5\ in particular, in that it is designed to promote 
just and equitable principles of trade, 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.
---------------------------------------------------------------------------

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

    Extending the implementation date for SR-ISE-2026-18 from ``on or 
before Q3 2026'' to ``on or before November 10, 2026'' is consistent 
with the protection of investors and the public interest because it 
will provide the Exchange with the additional time necessary to 
complete the technology development and testing. This will ensure that 
the Exchange has sufficient time to implement the changes in an orderly 
manner, thereby protecting investors and promoting the maintenance of 
fair and orderly markets.
    The Exchange does not propose any substantive changes to SR-ISE-
2026-18. The proposal only extends the outside date by which the 
Exchange must implement those changes. The Exchange will issue an 
Options Trader Alert to Members announcing the specific implementation 
date in advance of implementation.

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 not necessary or appropriate in 
furtherance of the purposes of the Act. The proposed rule change is not 
intended to address competitive issues but, rather, is intended solely 
to extend the implementation date of SR-ISE-2026-18. The extended 
implementation date does not impose any burden on intra-market 
competition because it will apply uniformly to all Members. The 
proposed rule change does not impose any burden on inter-market 
competition because it does not alter the substance of the rule change.

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

    No written comments were either solicited or received.

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

    Because the foregoing proposed rule change does not: (i) 
significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
become operative for 30 days from the date on which it was filed, or 
such shorter time as the Commission may designate, it has become 
effective pursuant to Section 19(b)(3)(A)(iii) of the Act \6\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\7\
---------------------------------------------------------------------------

    \6\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \7\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Commission deems this requirement to have been met.
---------------------------------------------------------------------------

    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 should be approved or disapproved.

IV. Solicitation of Comments

change is consistent with the Act. Comments may be submitted by any of
