(“BX” 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 text of the proposed rule change is available on the Exchange's website at https://listingcenter.nasdaq.com/rulebook/bx/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 purpose of the proposed rule change is to amend the Exchange's Cabinet Proximity Option Fee at General 8, Section 1(d) by establishing a reservation fee for cabinets with power densities greater than 10 kilowatts (“kW”).

The Exchange currently offers a Cabinet Proximity Option program where, for a monthly fee, customers can obtain an option for future use on available, unused cabinet space in proximity to their existing equipment. Cabinets reserved under the Cabinet Proximity Option program are unused cabinets that customers reserve for future use and can be converted to a powered cabinet at the customer's request. Under the program, customers can reserve up to maximum of 20 cabinets that the Exchange endeavors to provide as close as reasonably possible to the customer's existing cabinet space, taking into consideration power availability within segments of the data center and the overall efficiency of use of data center resources as determined by the Exchange. Should reserved data center space be needed for use, the reserving customer will have three business days to formally contract with the Exchange for full payment for the reserved cabinet space or it will be reassigned. In making determinations to require exercise or relinquishment of reserved space as among numerous customers, the Exchange will take into consideration several factors, including: proximity between available reserved cabinet space and the existing space of a customer seeking additional space for actual cabinet usage; a customer's ratio of cabinets in use to those reserved; the length of time that a particular reservation(s) has been in place; and any other factor that the Exchange deems relevant to ensure overall efficiency in use of the data center space.

The applicable monthly fees for the Cabinet Proximity Option program are in General 8, Section 1(d). The Cabinet Proximity Option fee is $1,055/month per medium or low density cabinets and $1,583/month per medium/high or high density cabinets. The Exchange proposes to establish a Cabinet Proximity Option fee of $3,000 for cabinets with power densities greater than 10 kW. As such, the Exchange proposes to amend its fee schedule at General 8, Section 1(d) to reflect the addition to the existing Cabinet Proximity Option fees.

Currently, the Exchange offers Super High Density Cabinets with power densities greater than 10 kW and less than or equal to 17.3 kW. In addition, the Exchange intends to expand its data center and offer cabinets with increased power densities in the future, including power densities greater than 17.3 kW. Customers will not be liable to pay fees under the Cabinet Proximity Option program until such time as cabinets can be converted to powered cabinets. To be clear, the Cabinet Proximity Option fee of $3,000 for cabinets with power densities greater than 10 kW would apply to any such reservations in the existing data center. Although the Exchange has an expansion of the data center underway, the fees for the Cabinet Proximity Option program would not apply to the expanded data center until the expansion is operational and cabinets are available and able to be converted to powered cabinets.

The proposed Cabinet Proximity Option fee of $3,000 would only be charged to those customers that voluntarily choose to reserve cabinets with power densities greater than 10 kW. Such option is available to all customers. Similar to other fees related to cabinet and power usage, the Cabinet Proximity Option fee is incremental, with higher fees being imposed based on higher levels of cabinet and power allocation. The proposed Cabinet Proximity Option fee of $3,000 for cabinets with power densities greater than 10 kW is comparable to pricing for “PNU cabinets” available to customers of co-location facilities of the New York Stock Exchange LLC (“NYSE”), which charges a monthly fee of $360 per kW for PNU cabinets.

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.

First, the proposal is reasonable because the proposed fee is comparable to NYSE's monthly fee of $360 per kW for PNU cabinets. As noted above, NYSE offers “PNU cabinets,” which are reserved cabinets that are not active and can be converted to powered, dedicated cabinets when the user requests. The Exchange's proposal would establish a flat $3,000 Cabinet Proximity Option fee for cabinets with power densities greater than 10 kW. Under NYSE's fee schedule, a reservation for a cabinet with power density equal to 10 kW would be $3,600 ( e.g., 10 kW × $360). Because NYSE's PNU cabinet fees are charged on a per kW basis, PNU cabinet fees for cabinets with power densities greater than 10 kW would be more than $3,600 and increase as the power density of the cabinet increases. Therefore, the Exchange's proposal reflects a discounted price to reserve such cabinets as compared to NYSE's fees for comparable PNU cabinets.

Furthermore, the Exchange offers the Cabinet Proximity Option program as a convenience to customers, providing an option to reserve unused cabinet space in proximity to their existing equipment. No firms are required to reserve cabinets via the Cabinet Proximity Option program. Clients may simply order cabinets without utilizing reservations. The proposed Cabinet Proximity Option fee of $3,000 would only be charged to those customers that voluntarily choose to reserve cabinets with power densities greater than 10 kW and such option is available to all customers.

The Exchange believes substitutable products and services are available to market participants, including, among other things, other equities and options exchanges that a market participant may connect to in lieu of the Exchange, connectivity to the Exchange via a third-party reseller of connectivity, and/or trading of equities or options products within markets which do not require connectivity to the Exchange, such as the Over-the-Counter (OTC) markets. Market participants that wish to connect to the Exchange will continue to choose the method of connectivity based on their specific needs. Market participants that wish to connect to the Exchange but want to avoid or mitigate the effect of this proposed fee can choose to connect to the Exchange through a vendor (or order cabinets without reservations, as noted above).

In offering the Cabinet Proximity Option the Exchange incurs certain costs, including costs related to the data center, including maintaining an adequate level of power so that reserved cabinets can be available and powered on promptly at the request of customers.

If the Exchange is incorrect in its determination that the proposed fee reflects the value of the Cabinet Proximity Option for cabinets with power densities greater than 10 kW, customers will not reserve such cabinets.

In summary, the proposal represents an equitable allocation of reasonable dues, fees and other charges because the proposed fee is less than NYSE's fee for a comparable service, customers have choices in how they connect to the Exchange, and reservations under the Cabinet Proximity Option program are optional and provided as a convenience to customers.

The Exchange believes that the proposed fee change is not unfairly discriminatory because the Cabinet Proximity Option fee is assessed uniformly across all market participants that voluntarily select the option, which is available to all customers. All customers have the choice of whether and how to connect to the Exchange and may order cabinets without utilizing reservations.

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.

Nothing in the proposal burdens inter-market competition because approval of the proposal does not impose any burden on the ability of other exchanges to compete. The Exchange operates in a highly competitive market in which market participants can determine whether or not to connect to the Exchange based on the value received compared to the cost of doing so. Indeed, market participants have numerous alternative exchanges that they may participate on and direct their order flow, as well as off-exchange venues, where competitive products are available for trading.

Nothing in the proposal burdens intra-market competition because the Cabinet Proximity Option program is available to any customer under the same fees as any other customer, and any customer that wishes to reserve a cabinet pursuant to the Cabinet Proximity Option program can do so on a non-discriminatory basis.

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

The foregoing rule change has become effective pursuant to Section 19(b)(3)(A)(ii) of the Act.

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: (i) necessary or appropriate in the public interest; (ii) for the protection of investors; or (iii) 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.
