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 October 27, 2026, Nasdaq ISE, LLC (“ISE” or “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “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 proposes to amend the fees for Nasdaq 100® Index (“NDX”) ^[3] options in the Exchange's Pricing Schedule at Options 7, Section 5.A.

While the changes proposed herein are effective upon filing, the Exchange has designated the amendments become operative on November 1, 2026.

The text of the proposed rule change is available on the Exchange's website at listingcenter.nasdaq.com/​rulebook/​ise/​rulefilings, 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 increase the NDX and NDXP options fees for regular orders assessed to Non-Priority Customer ^[4] market participants in Options 7, Section 5.A. The Exchange also proposes some minor technical amendments to the Pricing Schedule. The changes are described below.

As set forth in Options 7, Section 5.A, the Exchange currently assesses a fee of $0.75 per contract for NDX and NDXP ( printed page 73335) Market Maker,^[5] Non-Nasdaq ISE Market Maker (FarMM),^[6] Firm Proprietary ^[7] /Broker-Dealer ^[8] and Professional Customer ^[9] regular orders. Priority Customer ^[10] orders are currently assessed a $0.50 per contract fee in NDX and NDXP.

The Exchange now proposes to increase the Non-Priority Customer NDX fees for regular orders from $0.75 to $1.25 per contract. As a result, Non-Priority Customer orders would each be assessed a fee of $1.25 per contract in NDX and NDXP. The Exchange is not proposing to amend the Priority Customer fee of $0.50 per contract in NDX or NDXP, or the fees for other index options in Options 7, Section 5.

The notes to Options 7, Section 5.A would continue to apply, unchanged. Specifically: (i) note 1 provides that, for all executions in complex NDX (and NDXP) ^[11] orders for Non-Priority Customers, the applicable complex order fees for Non-Select Symbols in Options 7, Section 4 will apply, and for all executions in complex NDX (and NDXP) ^[12] orders for Priority Customers, the fee will be $0.25 per contract; (ii) note 2 provides that a surcharge of $0.25 per contract is assessed to all Priority Customer complex executions in NDX (and NDXP); ^[13] (iii) note 3 provides that a surcharge of $0.25 per contract is assessed to all market participants for simple and complex executions in NDX (and NDXP) ^[14] with a premium price of $25.00 or greater; and (iv) note 4 provides that a surcharge is assessed to electronic simple Non-Priority Customer orders in NDX and NDXP that remove liquidity according to a premium schedule, which ranges from $1.00 per contract for premiums of less than $3.00 to $3.00 per contract for premiums greater than or equal to $50.00. Because complex NDX orders for Non-Priority Customers are assessed the Non-Select Symbol complex order fees in Options 7, Section 4 pursuant to note 1, the proposed fee increase would apply to Non-Priority Customer regular (simple) orders in NDX.

By way of example, under the proposed pricing a Market Maker electronic simple order in NDX with a premium of $5.00 that adds liquidity would be assessed $1.50 per contract ($1.25 fee plus the $0.25 per contract surcharge in section 5.D), as compared to $1.00 per contract today ($0.75 fee plus the $0.25 per contract surcharge in section 5.D). If the same order removed liquidity, it would be assessed $3.00 per contract (the $1.25 fee, the $0.25 per contract surcharge in section 5.D, plus the $1.50 note 4 surcharge), as compared to $2.50 per contract today (the $0.75 fee, the $0.25 per contract surcharge in section 5.D, plus the $1.50 note 4 surcharge). A Professional Customer simple order in NDX with a premium of $30.00 that adds liquidity would be assessed $1.75 per contract (the $1.25 fee plus the $0.25 surcharge in section 5.D plus the $0.25 note 3 surcharge) as compared to $1.25 per contract today (the $0.75 fee plus the $0.25 surcharge in section 5.D plus the $0.25 note 3 surcharge). By comparison, a Priority Customer simple order in NDX that adds liquidity with a premium of $30.00 would continue to be assessed $0.75 per contract (the $0.50 fee plus the $0.25 note 3 surcharge).

While the Exchange is increasing the NDX and NDXP Non-Priority Customer fee, the Exchange believes that market participants will continue to transact NDX and NDXP options on ISE given the large notional value of NDX. Each options contract has a multiplier of $100, so a single contract represents notional exposure equal to $100 times the index level. For example, at an index level of 20,000, one NDX contract represents approximately $2,000,000 in notional value. At that level, the proposed $1.25 per contract fee represents approximately 0.00625 basis points of notional value, and the proposed $0.50 increase represents approximately 0.0025 basis points. Because the Exchange's fees are assessed per contract regardless of the size of the underlying exposure, the cost of the fee relative to the economic exposure obtained is small. It remains small even after the proposed increase. The Exchange notes that the increase is modest relative to the value of the exposure each NDX contract provides.

The Exchange's proposal to note “and NDXP” in a few places in Options 7, Section 5,A. is a non-substantive change as “NDX” is defined to include a.m.-settled and p.m.-settled on NDX options. Adding NDXP will bring greater visibility to the rule text and conform the text.

2. Statutory Basis

The Exchange believes that its proposal is consistent with Section 6(b) of the Act,^[15] in general, and furthers the objectives of 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 members and issuers and other persons using any facility, and is not designed to permit unfair discrimination between customers, issuers, brokers, or dealers.

The Exchange believes that its proposal to increase the Non-Priority Customer NDX and NDXP fees for regular orders from $0.75 to $1.25 per contract is reasonable because Priority Customers will continue to be assessed a lower fee as compared to Non-Priority Customers, and the existing notes and surcharges in NDX and NDXP will continue to apply unchanged. The Exchange believes that, even with the increase, Non-Priority Customer pricing in NDX and NDXP will remain competitive and will continue to attract order flow to the Exchange.

The Exchange believes that the proposed Non-Priority Customer fee of $1.25 per contract in NDX and NDXP options is reasonable when considered in relation to the notional value of the product. Each NDX options contract has a multiplier of $100, so a single contract represents notional exposure equal to $100 times the index level.^[17] Because the Exchange's options fees are assessed per contract regardless of the size of the underlying exposure, the cost of the fee relative to the economic exposure obtained is small. It remains small even after the proposed increase. Viewed another way, a market participant seeking comparable Nasdaq 100 exposure through other products would generally need to trade many more contracts, each of which is subject to its own transaction fees. For example, a market participant seeking exposure equivalent to one NDX contract through ( printed page 73336) options overlying Invesco QQQ Trust (“QQQ”) ^[18] would need to trade approximately 41 QQQ options contracts. Those contracts would be subject to per-contract transaction fees of up to $0.45 each on the Exchange for an aggregate cost of approximately $18.45. On a notional-equivalent basis, therefore, the proposed NDX and NDXP options fees remain lower than the cost of obtaining similar exposure through alternative products. The Exchange also notes that the proposed fee is lower in some cases and higher in other cases than fees assessed by other exchanges for proprietary broad-based index options with similarly large notional values, such as S&P 500 Index (“SPX”) options on Cboe Exchange, Inc. (“Cboe”).^[19] For these reasons, the Exchange believes that the proposed fee increase, while meaningful in absolute terms, is modest relative to the value of the exposure each contract provides. The Exchange believes the increase will not discourage market participants from transacting in NDX and NDXP options on the Exchange.

Pricing by symbol is a common practice on many U.S. options exchanges as a means to incentivize order flow to be sent to an exchange for execution in particular products. The Exchange notes that market participants are offered different ways to gain exposure to the Nasdaq 100 Index, whether through Nasdaq proprietary products like options overlying NDX, NDXP or XND, or separately through multi-listed options overlying QQQ. Offering such products provides market participants with a variety of choices in selecting the product they desire to utilize in order to gain exposure to the Nasdaq 100 Index. Market participants also may trade competing proprietary broad-based index options on other exchanges, such as SPX and RUT options listed on Cboe.^[20]

The Exchange believes that its proposal to increase the Non-Priority Customer NDX and NDXP options fees for regular orders is equitable and not unfairly discriminatory because the increased fee will be applied uniformly to all Non-Priority Customers. Continuing to assess a lower NDX and NDXP options fees to Priority Customers as compared to Non-Priority Customers is equitable and not unfairly discriminatory because Priority Customer liquidity benefits all market participants by providing more trading opportunities, which attracts Market Makers. An increase in the activity of these market participants in turn facilitates tighter spreads, which may cause an additional corresponding increase in order flow from other market participants to the benefit of all market participants who may interact with the order flow.

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.

In terms of intra-market competition, the Exchange will apply the proposed Non-Priority Customer NDX and NDXP options fees uniformly to all Non-Priority Customers. Continuing to assess a lower NDX and NDXP options fees to Priority Customers as compared to Non-Priority Customers does not impose an undue burden on competition because Priority Customer liquidity benefits all market participants by providing more trading opportunities, which attracts Market Makers. An increase in the activity of these market participants in turn facilitates tighter spreads, which may cause an additional corresponding increase in order flow from other market participants to the benefit of all market participants who may interact with the order flow.

In terms of inter-market competition, the Exchange notes that it operates in a highly competitive market in which market participants can readily favor competing venues if they deem fee levels at a particular venue to be excessive. In such an environment, the Exchange must continually adjust its fees to remain competitive with other options exchanges. Because competitors are free to modify their own fees in response, and because market participants may readily adjust their order routing practices, the Exchange believes that the degree to which fee changes in this market may impose any burden on competition is extremely limited. As noted above, market participants are offered an opportunity to transact in NDX, NDXP, or XND, or separately execute options overlying QQQ. Offering these products provides market participants with a variety of choices in selecting the product they desire to use to gain exposure to the Nasdaq 100 Index.

In addition to the Exchange, market participants have alternative options exchanges that they may participate on and direct their order flow, which list proprietary products that compete with NDX and NDXP options.^[21] In sum, if the changes proposed herein are unattractive to market participants, it is likely that the Exchange will lose market share as a result. Accordingly, the Exchange does not believe that the proposed changes will impair the ability of members or competing options exchanges to maintain their competitive standing in the financial markets.
