The text of the proposed rule change is available on the Exchange's website at https://listingcenter.nasdaq.com/rulebook/mrx/rules, at the principal office of the Exchange, and at the Commission's Public Reference Room.

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 Options 7, Section 6, Ports and Other Services. Specifically, the Exchange proposes to amend the monthly caps for SQF Ports and SQF Purge Ports.

Today, MRX assesses $1,250 per port, per month for an SQF Port as well as an SQF Purge Port. Also, today, SQF Ports and SQF Purge Ports are subject to a monthly cap of $17,500, which cap is applicable to Market Makers.

At this time, the Exchange proposes to increase the monthly maximum SQF Port and SQF Purge Port Fee Cap of $17,500 for Market Makers based on the size of the Market Maker on MRX. The Exchange is determining the size of the Market Maker based on the amount of transactional volume executed on MRX in a given month. The Exchange proposes to take each Market's Maker's electronic monthly add liquidity transactional volume on MRX and dividing that number by the sum of all Market Maker electronic monthly add liquidity volume on MRX (“Transactional Volume”). Each Market Maker would then be classified on MRX, for the purpose of the SQF Port Fee and SQF Purge Port Fee Cap, as a “small,” “medium,” or “large” Market Maker based on their Transactional Volume on MRX to determine the applicable cap in a given month. Market Makers that qualify as “small” would be subject to an increased SQF Port and SQF Purge Port monthly cap of $22,500. Market Makers that qualify as “medium” would be subject to an increased monthly cap of $25,000 for SQF Port and SQF Purge Port Fees. Finally, Market Makers that qualify as “large” would be subject to an increased monthly cap of $27,500 for SQF Port and SQF Purge Port Fees.

As is the case today, the Exchange would not assess a Market Maker an SQF Port and SQF Purge Port Fee beyond the monthly cap once the Market Maker has exceeded the monthly cap for the respective month. Despite increasing the maximum SQF Port and SQF Purge Port Fee Cap for Market Makers that qualify as “small,” “medium” and “large,” the Exchange will continue to offer all Market Makers the opportunity to cap their SQF Port and SQF Purge Port Fees to limit their costs as they would not be assessed an SQF Port or SQF Purge Port Fee beyond the applicable cap each month.

A MRX Market Maker requires only one SQF Port to submit quotes in its assigned options series into MRX. An SQF Purge is a specific port for the SQF interface that only receives and notifies of purge requests from the Market Maker. A MRX Market Maker may submit all quotes through one SQF Port and utilize one SQF Purge Port to view its purge requests. While a Market Maker may elect to obtain multiple SQF Ports and SQF Purge Ports to organize its business, only one SQF Port and SQF Purge Port is necessary for a Market Maker to fulfill its regulatory quoting obligations.

2. Statutory Basis

The Exchange believes that its proposal is consistent with Section 6(b) of the Act, in general, and furthers the objectives of Sections 6(b)(4) and 6(b)(5) of the Act, 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 proposed pricing change to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “small,” from $17,500 to $22,500, to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “medium” from $27,500 to $25,000 per month, and to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “large” from $42,000 to $50,000 per month, is reasonable because despite the increase in the maximum SQF Port Fee and SQF Purge Port Fee Cap, the Exchange will continue to offer all Market Makers the opportunity to cap their SQF Port Fees each month to limit their cost as they would not be assessed an SQF Port or SQF Purge Port Fee Cap Fees beyond the cap.

A MRX Market Maker requires only one SQF Port to submit quotes in its assigned options series into MRX. A MRX Market Maker may submit all quotes through one SQF Port and utilize one SQF Purge Port to view its purge requests. While a Market Maker may elect to obtain multiple SQF Ports and SQF Purge Ports to organize its business, only one SQF Port and SQF Purge Port is necessary for a Market Maker to fulfill its regulatory quoting obligations. Members may choose a greater number of SQF Ports or SQF Purge Ports, beyond one port, depending on that Member's particular business model. Additionally, the Exchange believes that the caps are reasonable for two reasons.

First, SQF Ports are a secure method for Market Makers to submit quotes into the Exchange's match engine and for the Exchange to send messages related to those quotes to Market Makers. MRX must manage the security and message traffic, among other things, for each port. Utilizing the various caps based on the “size” of the Market Maker as determined by Transactional Volume, provides every Market Maker the ability to manage cost. Additionally, the Exchange would have the ability to manage the quantity of SQF Ports and SQF Purge Ports issued by the Exchange. The various SQF Port and SQF Purge Port Fee Caps were determined based on the level of Transactional Volume on MRX in 2024 for Market Makers. The Exchange assessed each level of Market Maker an increased fee based on size, as reflected by Transactional Volume, to reflect the various sizes of Market Makers present on the Exchange at this time. By capping the SQF Ports and SQF Purge Ports at different levels based on “size,” the Exchange is considering the message traffic and message rates generated by the various “sizes” of Market Makers and the Exchange's ability to process messages from all SQF Ports and SQF Purge Ports. The SQF Port and SQF Purge Port Fee Cap would allow the Exchange to scale its needs with respect to processing messages in an efficient manner. The Exchange notes that Cboe Exchange, Inc. (“Cboe”) limits usage on each port and assesses fees for incremental usage.

Second, the Exchange notes that multiple ports are not necessary, however, to the extent that some Market Makers elect to obtain multiple SQF Ports and SQF Purge Ports, the Exchange is offering to cap their total port cost. MRX believes the existence of a cap based on the “size” of the Market Maker will level the playing field. The Exchange believes that this approach enables various types of Market Makers to effectively limit costs based on their executed Transactional Volume on the Exchange. Further, the existence of an SQF Port and SQF Purge Port Fee Cap allows for efficiencies and permits Market Makers to increase their number of ports beyond the cap. The cap levels the playing field by allowing various types of Market Makers that want to obtain a larger number of ports to do so with the certainty of a fee cap. Without the SQF Port and SQF Purge Port Fee Cap, Market Makers may pay more to obtain multiple SQF Port and SQF Purge Ports on the Exchange. Other markets tier port fees. BOX Exchange LLC (“BOX”) assesses $1,000 per month for all SAIL Ports for Market Making and $500 per month per port up to 5 ports for order entry and $150 per month for each additional port. Miami International Securities Exchange, LLC's (“MIAX”) MIAX Express Interface (“MEI”) Fee levels are based on a tiered fee structure based on the Market Maker's total monthly executed volume during the relevant month.

The proposed pricing change to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “small,” from $17,500 to $22,500, to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “medium” from $27,500 to $25,000 per month, and to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “large” from $42,000 to $50,000 per month, is equitable and not unfairly discriminatory because the Exchange is offering different sizes of Market Makers, based on Transactional Volume executed on the Exchange, the ability to cap their costs at different levels and potentially obtain some SQF Ports and SQF Purge Ports at no cost. The proposal recognizes that some Market Makers may be deemed “small” and may not be able to achieve the same cap as other Market Makers. To this end, the Exchange proposes to increase SQF Port and SQF Purge Port Fee Cap from $17,500 to $22,500 per month for Market Makers that qualify as “small.” To the extent that a Market Maker qualifies in a given month as a “medium” Market Maker the Exchange proposes to increase the cap from $17,500 to $25,000 per month. This fee presumes to place a Market Maker that qualifies as “medium” on equal footing with a Market Maker that qualifies as a “small” Market Maker in terms of the cap, by setting different fee caps for each group. The proposal presumes, that based on Transactional Volume, these Market Makers that qualify as “medium” have a greater ability to obtain a greater amount of SQF Ports and SQF Purge Ports as compared to Market Makers that qualify as “small.” Finally, to the extent that a Market Maker qualifies in a given month as a “large” Market Maker the Exchange proposes to increase the cap from $17,500 to $27,500 per month. This fee presumes to place a Market Maker that qualifies as “large” on equal footing with a Market Maker that qualifies as a “small” Market Maker and a Market Maker that qualifies as “medium” in terms of the cap by setting different fee caps for each group. The proposal presumes that based that based on Transactional Volume these Market Makers that qualify as “large” have the ability to obtain the largest amount of SQF Ports and SQF Purge Ports. The Exchange would uniformly apply the appropriate Market Maker cap to each Market Maker group based on the same volume calculation. Also, Market Makers who exceed their applicable cap would uniformly not be assessed any fee for SQF Ports and SQF Purge Ports beyond the applicable maximum amount.

Market Makers are the only market participants that are assessed SQF Port and SQF Purge Port fees because they are the only market participants that are permitted to quote on the Exchange. SQF Ports and SQF Purge Ports are only utilized in the Market Maker's assigned options series. Unlike other market participants, Market Makers are subject to market making and quoting obligations. These liquidity providers are critical market participants in that they are the only market participants that provide liquidity to MRX on a continuous basis. In addition, the Exchange notes that Lead Market Makers are required to submit quotes in the Opening Process to open an options series. Market Makers are subject to a number of fees, unlike other market participants. Market Makers pay separate Membership Fees, and CMM Trading Right Fees, in addition to other fees paid by other market participants. Providing Market Makers a means to cap their cost related to quoting at a rate that reflects their “size” and enabling all Market Makers to acquire SQF Ports and SQF Purge Ports at no cost beyond the applicable cap enables these market participants to provide the necessary liquidity to MRX at lower costs. Therefore, because Market Makers fulfill a unique role on the Exchange, are the only market participant required to submit quotes as part of their obligations to operate on the Exchange, and, in light of that role, they are eligible for certain incentives. The proposed SQF Port and SQF Purge Fee cap is designed to continue to incent Market Makers to quote on MRX, thereby promoting liquidity, quote competition, and trading opportunities.

In 2022, NYSE Arca, Inc. (“NYSE Arca”) proposed to restructure fees relating to OTPs for Market Makers. In that rule change, NYSE Arca argued that,

Market Makers serve a unique and important function on the Exchange (and other options exchanges) given the quote-driven nature of options markets. Because options exchanges rely on actively quoting Market Makers to facilitate a robust marketplace that attracts order flow, options exchanges must attract and retain Market Makers, including by setting competitive Market Maker permit fees. Stated otherwise, changes to Market Maker permit fees can have a direct effect on the ability of an exchange to compete for order flow. The Exchange also believes that the number of options exchanges on which Market Makers can effect option transactions also ensures competition in the marketplace and constrains the ability of exchanges to charge supracompetitive fees for access to its market by Market Makers.

Further, NYSE ARCA noted that,

The Exchange further believes that its ability to set Market Maker permit fees is constrained by competitive forces based on the fact that Market Makers can, and have, chosen to terminate their status as a Market Maker if they deem Market Maker permit fees to be unreasonable or excessive. Specifically, the Exchange notes that a BOX participant modified its access to BOX in connection with the implementation of a proposed change to BOX's Market Maker permit fees. The Exchange has also observed that another options exchange group experienced decreases in market share following its proposed modifications of its access fees (including Market Maker trading permit fees), suggesting that market participants (including Market Makers) are sensitive to changes in exchanges' access fees and may respond by shifting their order flow elsewhere if they deem the fees to be unreasonable or excessive.

There is no requirement, regulatory or otherwise, that any Market Maker connect to and access any (or all of) the available options exchanges. The Exchange also is not aware of any reason why a Market Maker could not cease being a permit holder in response to unreasonable price increases. The Exchange does not assess any termination fee for a Market Maker to drop its OTP, nor is the Exchange aware of any other costs that would be incurred by a Market Maker to do so.

The Exchange likewise believes that its ability to cap SQF Port and SQF Purge Port fees is constrained by competitive forces and that its proposed modifications to the SQF Port and SQF Purge Fee cap is reasonably designed in consideration of the competitive environment in which the Exchange operates, by balancing the value of the enhanced benefits available to Market Makers, based on their transactional volume and presumed “size.” At the same time, the Exchange believes the proposed fees will incent Market Makers to support increased liquidity, quote competition, and trading opportunities on the Exchange, for the benefit of all market participants.

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.

Intermarket Competition

The proposal does not impose an undue burden on intermarket 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 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.

Intramarket Competition

The proposed pricing change to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “small,” from $17,500 to $22,500, to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “medium” from $27,500 to $25,000 per month and to increase the SQF Port Fee and SQF Purge Port Fee Cap for Market Makers that qualify as “large” from $42,000 to $50,000 per month does not impose an undue burden on competition because the Exchange is offering different sizes of Market Makers, based on Transactional Volume executed on the Exchange, the ability to cap their costs at different levels and potentially obtain some SQF Ports and SQF Purge Ports at no cost. The proposal recognizes that some Market Makers may be deemed “small” and may not be able to achieve the same cap as other Market Makers. To this end, the Exchange proposes to increase SQF Port and SQF Purge Port Fee Cap from $17,500 to $22,500 per month for Market Makers that qualify as “small.” To the extent that a Market Maker qualifies in a given month as a “medium” Market Maker the Exchange proposes to increase the cap from $17,500 to $25,000 per month. This fee presumes to place a Market Maker that qualifies as “medium” on equal footing with a Market Maker that qualifies as a “small” Market Maker in terms of the cap, by setting different fee caps for each group. The proposal presumes, that based on Transactional Volume, these Market Makers that qualify as “medium” have a greater ability to obtain a greater amount of SQF Ports and SQF Purge Ports as compared to Market Makers that qualify as “small.” Finally, to the extent that a Market Maker qualifies in a given month as a “large” Market Maker the Exchange proposes to increase the cap from $17,500 to $27,500 per month. This fee presumes to place a Market Maker that qualifies as “large” on equal footing with a Market Maker that qualifies as a “small” Market Maker and a Market Maker that qualifies as “medium” in terms of the cap by setting different fee caps for each group. The proposal presumes that based that based on Transactional Volume these Market Makers that qualify as “large” have the ability to obtain the largest amount of SQF Ports and SQF Purge Ports. The Exchange would uniformly apply the appropriate Market Maker cap to each Market Maker group based on the same volume calculation. Also, Market Makers who exceed their applicable cap would uniformly not be assessed any fee for SQF Ports and SQF Purge Ports beyond the applicable maximum amount.

Market Makers are the only market participants that are assessed SQF Port and SQF Purge Port fees because they are the only market participants that are permitted to quote on the Exchange. SQF Ports and SQF Purge Ports are only utilized in the Market Maker's assigned options series. Unlike other market participants, Market Makers are subject to market making and quoting obligations. These liquidity providers are critical market participants in that they are the only market participants that provide liquidity to MRX on a continuous basis. In addition, the Exchange notes that Lead Market Makers are required to submit quotes in the Opening Process to open an options series. Market Makers are subject to a number of fees, unlike other market participants. Market Makers pay separate Membership Fees, and CMM Trading Right Fees, in addition to other fees paid by other market participants. Providing Market Makers a means to cap their cost related to quoting at a rate that reflects their “size” and enabling all Market Makers to acquire SQF Ports and SQF Purge Ports at no cost beyond the applicable cap enables these market participants to provide the necessary liquidity to MRX at lower costs. Therefore, because Market Makers fulfill a unique role on the Exchange, are the only market participant required to submit quotes as part of their obligations to operate on the Exchange, and, in light of that role, they are eligible for certain incentives. The proposed SQF Port and SQF Purge Fee cap is designed to continue to incent Market Makers to quote on MRX, thereby promoting liquidity, quote competition, and trading opportunities.
