I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to amend Exchange Rule General 8 to establish 
fees for Liquid-Cooled Cabinets installation, Liquid-Cooled Cabinet 
Power Installation and Liquid-Cooled Cabinet Power in the Exchange's 
expanded data center. While these amendments are immediately effective, 
the Exchange proposes to implement the proposed fees during the fourth 
calendar quarter (``Q4'') of 2026. The Exchange will notify customers 
of the implementation date by Trader Alert.
    The text of the proposed rule change is available on the Exchange's 
website at <a href="https://listingcenter.nasdaq.com/rulebook/phlx/rulefilings">https://listingcenter.nasdaq.com/rulebook/phlx/rulefilings</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's current data center in Carteret, New Jersey, 
consists of the original data center, also known as ``NY11,'' and 
expansion areas NY11-4 and NY11-5. The Exchange proposes to amend Rule 
General 8, Section 1 to establish fees for Liquid-Cooled Cabinets 
installation, Liquid-Cooled Cabinet Power Installation, and Liquid-
Cooled Cabinet Power in NY11-5. The Exchange previously filed to expand 
its co-location services by offering Liquid-Cooled Cabinets in NY11-
5.\3\ In that filing, the Exchange stated that it would submit a 
separate fee filing to establish fees for those services. This proposed 
rule change establishes those fees.
---------------------------------------------------------------------------

    \3\ See Securities Exchange Act Release No. 105009 (Mar. 16, 
2026), 91 FR 13381 (Mar. 19, 2026) (SR-Phlx-2026-10).
---------------------------------------------------------------------------

    Currently, co-location customers have the option of obtaining a 
cabinet capable of accommodating varying power options. Co-location 
customers may obtain a Cabinet and choose among varying power options 
as provided under Rule General 8, Section 1. In an earlier proposal, 
the Exchange introduced an additional cabinet option in NY11-5. 
Specifically, the Exchange introduced a cabinet featuring liquid 
cooling, a cooling method that uses liquid, rather than air, to absorb 
and transfer heat away from equipment, such as servers (``Liquid-Cooled 
Cabinet''). Depending on business needs of data center customers, a 
Liquid-Cooled Cabinet might be more attractive to data center customers 
because liquid cooling is more efficient and enables space optimization 
in ways that air cooling methods would struggle to support. For 
example, a Liquid-Cooled Cabinet could handle greater power densities 
within a given space than would air cooling. For data center customers, 
this translates into the ability to deploy more computing power within 
the same cabinet footprint. In effect, Liquid-Cooled Cabinets allow 
data center customers to install more of the computing equipment that 
data center customers typically use within their cabinet than they 
would with air cooling methods because liquid cooling is more efficient 
at dissipating heat from a given cabinet space. The Exchange notes that 
data center customers prefer denser environments to minimize distance 
between equipment and thus maximize computing power within a given 
space. The Liquid-Cooled Cabinet option is only offered in NY11-5 
because the required liquid-cooled infrastructure necessary to support 
the proposed cabinets is not available in other parts of the data 
center. The Exchange notes that Liquid-Cooled Cabinets are offered as 
one other option for data center customers to choose from because 
traditionally cooled cabinets throughout the data center will continue 
to provide the level of thermal management appropriate for each cabinet 
offering that the Exchange provides.
    As discussed above, the Exchange is offering the Liquid-Cooled 
Cabinets as a convenience to its customers and notes that use of co-
location services, including the proposed Liquid-Cooled Cabinet 
service, is completely optional. Liquid-Cooled Cabinets are an optional 
premium co-location offering designed to support customer equipment 
with enhanced cooling capabilities. Co-location services, including the 
proposed offering, are voluntary, and each customer may determine 
whether any co-location option is appropriate for its business needs.
    The Exchange proposes to establish separate installation fees for 
Liquid-Cooled Cabinets under Rule General 8, Section 1(a). Customers 
may elect to use a Nasdaq-provided Liquid-Cooled Cabinet or, unlike 
traditional air-cooled cabinets that must be Nasdaq-provided, may 
supply their own Liquid-Cooled Cabinet for use within the dedicated 
liquid-cooling enclosure in NY11-5. For a Nasdaq-provided Liquid-Cooled 
Cabinet, the Exchange proposes to assess an installation fee of $5,490 
and no ongoing monthly fee. The proposed $5,490 installation fee is the 
same NY11-4/-5 installation fee currently applicable to a standard 
Cabinet under Rule General 8, Section 1(a). For a customer-provided 
Liquid-Cooled Cabinet, the Exchange proposes to assess an installation 
fee of $2,500 and no ongoing monthly fee.
    Providing both options is appropriate because the Liquid-Cooled 
Cabinet offering is purpose-built for the customer within a dedicated 
enclosure specifically designed to support the customer's liquid-
cooling infrastructure requirements. Depending on the customer's 
particular equipment and infrastructure needs, a customer-provided 
cabinet may be more appropriate, while other customers may prefer the 
convenience of a Nasdaq-provided cabinet. The proposed customer-
provided cabinet installation fee reflects the separate installation 
work associated with permitting the customer to use its own Liquid-
Cooled Cabinet within the dedicated NY11-5

[[Page 61479]]

liquid-cooling environment, while the proposed Nasdaq-provided cabinet 
installation fee reflects the furnishing and installation of a Nasdaq-
provided Liquid-Cooled Cabinet. Unlike the installation of a 
traditional air-cooled cabinet, installation of a Liquid-Cooled Cabinet 
involves specialized infrastructure within the dedicated NY11-5 liquid-
cooling environment and additional coordination to support the 
customer's liquid-cooling requirements.
    The Exchange also proposes to establish installation and ongoing 
monthly fees for Liquid-Cooled Cabinet Power as follows.
    Liquid-Cooled Cabinet Power would be available only in connection 
with Liquid-Cooled Cabinets in NY11-5 and would be subject to a one-
year, two-year, or three-year commitment, as selected by the customer. 
The installation fee for Liquid-Cooled Cabinet Power would consist of 
the applicable standard NY11-4/-5 cabinet power installation fee, as 
set forth in Rule General 8, Section 1(c), plus an additional per-kVA 
\4\ Liquid-Cooled Cabinet Power installation charge. The additional 
per-kVA installation charge would be $1,800 per kVA for a one-year 
commitment, $1,650 per kVA for a two-year commitment, and $1,500 per 
kVA for a three-year commitment. The ongoing monthly fee would be 
assessed per kVA based on the customer's selected commitment term: 
$1,000 per kVA per month for a one-year commitment, $900 per kVA per 
month for a two-year commitment, and $800 per kVA per month for a 
three-year commitment.
---------------------------------------------------------------------------

    \4\ Kilovolt-Amperes (kVA) is a unit of apparent power used to 
describe the capacity of electrical circuits and equipment. In 
alternating current (AC) systems, power consists of two components: 
real power (kW) and reactive power (kVAR). Real power, or kW, is the 
actual usable power that performs work, such as running servers or 
cooling systems, whereas reactive power, or kVAR, is the power that 
sustains the magnetic and electric fields in equipment but does not 
perform useful work. Because AC systems often have both real and 
reactive components, kVA measures the total apparent power, which is 
the combination of real and reactive power--the full load the 
circuit must carry. The relationship between kilowatts and kVA 
depends on the power factor (PF) which reflects how efficiently 
electrical power is converted into useful work: kW = kVA x PF. In 
the context of data center operations, electrical power is commonly 
expressed in two units: kilowatts (kW) and kilovolt-amperes (kVA). 
While these terms measure different aspects of electrical power--kW 
representing real power consumed by equipment and kVA representing 
apparent power supplied--they are closely correlated in environments 
where the power factor approaches unity. Modern data centers 
typically operate at or near a power factor of 1.0, resulting in 
minimal variance between kW and kVA. Accordingly, these measures, kW 
and kVA, are often treated as interchangeable for practical 
purposes.

---------------------------------------------------------------------------

[[Page 61480]]

    The Exchange calculates the amount of power associated with each 
Liquid-Cooled Cabinet Power option using the same general power-based 
methodology reflected in its existing cabinet power fee schedule. For 
single-phase power options, the Exchange calculates kVA by multiplying 
volts by amps and dividing by 1,000. For three-phase power options, the 
Exchange calculates kVA by multiplying volts by amps by the square root 
of three, and then dividing by 1,000.\5\
    For the Single Phase 240 Volt 20 Amp option, the Exchange 
calculates the associated kVA as 240 volts multiplied by 20 amps, 
divided by 1,000, which equals 4.80 kVA.
    The ongoing monthly fee is calculated by multiplying 4.80 kVA by 
the applicable monthly per-kVA rate. Accordingly, the proposed ongoing 
monthly fee would be $4,800 for a one-year commitment, $4,320 for a 
two-year commitment, and $3,840 for a three-year commitment. The 
installation fee is calculated by adding the applicable $3,600 standard 
NY11-4/-5 installation fee to the additional per-kVA Liquid-Cooled 
Cabinet Power installation charge. Accordingly, the proposed 
installation fee would be $12,240 for a one-year commitment, calculated 
as $3,600 plus 4.80 kVA multiplied by $1,800; $11,520 for a two-year 
commitment, calculated as $3,600 plus 4.80 kVA multiplied by $1,650; 
and $10,800 for a three-year commitment, calculated as $3,600 plus 4.80 
kVA multiplied by $1,500.
    For the Single Phase 240 Volt 32 Amp option, the Exchange 
calculates the associated kVA as 240 volts multiplied by 32 amps, 
divided by 1,000, which equals 7.68 kVA. The ongoing monthly fee is 
calculated by multiplying 7.68 kVA by the applicable monthly per-kVA 
rate. Accordingly, the proposed ongoing monthly fee would be $7,680 for 
a one-year commitment, $6,912 for a two-year commitment, and $6,144 for 
a three-year commitment. The installation fee is calculated by adding 
the applicable $3,600 standard NY11-4/-5 installation fee to the 
additional per-kVA Liquid-Cooled Cabinet Power installation charge. 
Accordingly, the proposed installation fee would be $17,424 for a one-
year commitment, calculated as $3,600 plus 7.68 kVA multiplied by 
$1,800; $16,272 for a two-year commitment, calculated as $3,600 plus 
7.68 kVA multiplied by $1,650; and $15,120 for a three-year commitment, 
calculated as $3,600 plus 7.68 kVA multiplied by $1,500.
    For the Single Phase 240 Volt 40 Amp option, the Exchange 
calculates the associated kVA as 240 volts multiplied by 40 amps, 
divided by 1,000, which equals 9.60 kVA. The ongoing monthly fee is 
calculated by multiplying 9.60 kVA by the applicable monthly per-kVA 
rate. Accordingly, the proposed ongoing monthly fee would be $9,600 for 
a one-year commitment, $8,640 for a two-year commitment, and $7,680 for 
a three-year commitment. The installation fee is calculated by adding 
the applicable $3,600 standard NY11-4/-5 installation fee to the 
additional per-kVA Liquid-Cooled Cabinet Power installation charge. 
Accordingly, the proposed installation fee would be $20,880 for a one-
year commitment, calculated as $3,600 plus 9.60 kVA multiplied by 
$1,800; $19,440 for a two-year commitment, calculated as $3,600 plus 
9.60 kVA multiplied by $1,650; and $18,000 for a three-year commitment, 
calculated as $3,600 plus 9.60 kVA multiplied by $1,500.
    For the 3 Phase 415 Volt 20 Amp option, the Exchange calculates the 
associated kVA as 415 volts multiplied by 20 amps multiplied by the 
square root of three, divided by 1,000, which equals approximately 
14.38 kVA. The ongoing monthly fee is calculated by multiplying 
approximately 14.38 kVA by the applicable monthly per-kVA rate. 
Accordingly, the proposed ongoing monthly fee would be $14,375.60 for a 
one-year commitment, $12,938.04 for a two-year commitment, and 
$11,500.48 for a three-year commitment. The installation fee is 
calculated by adding the applicable $4,560 standard NY11-4/-5 
installation fee to the additional per-kVA Liquid-Cooled Cabinet Power 
installation charge. Accordingly, the proposed installation fee would 
be $30,436.08 for a one-year commitment, calculated as $4,560 plus 
approximately 14.38 kVA multiplied by $1,800; $28,279.74 for a two-year 
commitment, calculated as $4,560 plus approximately 14.38 kVA 
multiplied by $1,650; and $26,123.40 for a three-year commitment, 
calculated as $4,560 plus approximately 14.38 kVA multiplied by $1,500.
    For the 3 Phase 415 Volt 32 Amp option, the Exchange calculates the 
associated kVA as 415 volts multiplied by 32 amps multiplied by the 
square root of three, divided by 1,000, which equals approximately 
23.00 kVA. The ongoing monthly fee is calculated by multiplying 
approximately 23.00 kVA by the applicable monthly per-kVA rate. 
Accordingly, the proposed ongoing monthly fee would be $23,000.96 for a 
one-year commitment, $20,700.86 for a two-year commitment, and 
$18,400.77 for a three-year commitment. The installation fee is 
calculated by adding the applicable $4,560 standard NY11-4/-5 
installation fee to the additional per-kVA Liquid-Cooled Cabinet Power 
installation charge. Accordingly, the proposed installation fee would 
be $45,961.73 for a one-year commitment, calculated as $4,560 plus 
approximately 23.00 kVA multiplied by $1,800; $42,511.58 for a two-year 
commitment, calculated as $4,560 plus approximately 23.00 kVA 
multiplied by $1,650; and $39,061.44 for a three-year commitment, 
calculated as $4,560 plus approximately 23.00 kVA multiplied by $1,500.

    For the 3 Phase 415 Volt 40 Amp option, the Exchange calculates the 
associated kVA as 415 volts multiplied by 40 amps multiplied by the 
square root of three, divided by 1,000, which equals approximately 
28.75 kVA. The ongoing monthly fee is calculated by multiplying 
approximately 28.75 kVA by the applicable monthly per-kVA rate. 
Accordingly, the proposed ongoing monthly fee would be $28,751.20 for a 
one-year commitment, $25,876.08 for a two-year commitment, and 
$23,000.96 for a three-year commitment. The installation fee is 
calculated by adding the applicable $4,560 standard NY11-4/-5 
installation fee to the additional per-kVA Liquid-Cooled Cabinet Power 
installation charge. Accordingly, the proposed installation fee would 
be $56,312.16 for a one-year commitment, calculated as $4,560 plus 
approximately 28.75 kVA multiplied by $1,800; $51,999.48 for a two-year 
commitment, calculated as $4,560 plus approximately 28.75 kVA 
multiplied by $1,650; and $47,686.80 for a three-year commitment, 
calculated as $4,560 plus approximately 28.75 kVA multiplied by $1,500.
    For the 3 Phase 415 Volt 60 Amp option, the Exchange calculates the 
associated kVA as 415 volts multiplied by 60 amps multiplied by the 
square root of three, divided by 1,000, which equals approximately 
43.13 kVA. The ongoing monthly fee is calculated by multiplying 
approximately 43.13 kVA by the applicable monthly per-kVA rate. 
Accordingly, the proposed ongoing monthly fee would be $43,130 for a 
one-year commitment, $38,817 for a two-year commitment, and $34,504 for 
a three-year commitment. The installation fee is calculated by adding 
the applicable $4,560 standard NY11-4/-5 installation fee to the 
additional per-kVA Liquid-Cooled Cabinet Power installation charge. 
Accordingly, the proposed installation fee would be $82,194 for a one-
year commitment, calculated as $4,560 plus approximately 43.13 kVA 
multiplied by $1,800; $75,724.50 for a two-year commitment, calculated 
as $4,560 plus approximately 43.13 kVA multiplied by $1,650; and 
$69,255 for a three-year commitment, calculated as $4,560 plus 
approximately 43.13 kVA multiplied by $1,500.
    The proposed installation and ongoing monthly fees therefore scale 
with the amount of electrical capacity associated with the selected 
Liquid-Cooled Cabinet Power option and the length of the customer's 
selected commitment term. This structure applies the same calculation 
consistently across the available Liquid-Cooled Cabinet Power options 
while providing customers that elect longer commitment terms with lower 
per-kVA rates.
    The Exchange proposes separate cabinet installation fees and tiered 
Liquid-Cooled Cabinet Power pricing to reflect the optional nature of 
the offering and the different services customers may elect. The 
proposed $5,490 installation fee for a Nasdaq-provided Liquid-Cooled 
Cabinet is consistent with the existing NY11-4/-5 installation fee for 
a standard Cabinet under Rule General 8, Section 1(a), and no ongoing 
monthly cabinet fee would apply. The proposed $2,500 installation fee 
for a customer-provided Liquid-Cooled Cabinet reflects the separate 
installation work associated with permitting the customer to use its 
own Liquid-Cooled Cabinet within the dedicated NY11-5 liquid-cooling 
environment, and no ongoing monthly cabinet fee would apply. The 
proposed tiered pricing for Liquid-Cooled Cabinet Power provides 
customers with lower effective rates for longer-term commitments, which 
supports the Exchange's continued investment in making this specialized 
optional offering available. The proposed fees are higher than the fees 
applicable to standard air-cooled cabinets and associated power because 
Liquid-Cooled Cabinets are a premium product that provide enhanced 
liquid-cooling functionality and require specialized infrastructure, 
shared cooling capacity, and additional operational support beyond 
those required for standard co-location cabinets. The Exchange believes 
that the proposed fees are designed to reflect the value of the 
enhanced functionality, specialized infrastructure, customer choice, 
and dedicated capacity associated with Liquid-Cooled Cabinets and 
Liquid-Cooled Cabinet Power, while helping to support the Exchange's 
continued investment in this optional premium offering.
    The proposed Liquid-Cooled Cabinet offering is optional. Customers 
are not required to purchase Liquid-Cooled Cabinet installation, 
Liquid-Cooled Cabinet Power Installation or Liquid-Cooled Cabinet Power 
to connect to the Exchange, to maintain co-location services, or to 
access any Exchange system. Customers may continue to use existing 
cabinet and power offerings under Rule General 8, Section 1, as 
applicable. Customers that elect the Liquid-Cooled Cabinet offering may 
choose between a Nasdaq-provided Liquid-Cooled Cabinet and a customer-
provided Liquid-Cooled Cabinet based on their business and 
infrastructure needs.
    The Exchange is offering Liquid-Cooled Cabinets in response to 
customer demand for infrastructure capable of supporting increasingly 
power-dense computing equipment. Although the Exchange is not aware of 
another exchange that currently offers a comparable liquid-cooled 
cabinet product in its co-location fee schedule, liquid-cooling 
technology is available in the broader data center industry and is not 
novel in data center or communications infrastructure. Accordingly, the 
proposal reflects the Exchange's effort to make available, as an 
optional premium co-location service, an infrastructure option that is 
responsive to evolving customer equipment and cooling needs. The 
Exchange proposes to implement the proposed fees during Q4 of 2026. The 
Exchange will notify customers of the implementation date by Trader 
Alert.
2. Statutory Basis
    The Exchange believes that the proposed rule change 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, because 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 the proposed fees are reasonable because 
they are designed to reflect the value of the enhanced functionality, 
specialized infrastructure, customer choice, and dedicated capacity 
associated with Liquid-Cooled Cabinets and Liquid-Cooled Cabinet Power, 
while helping to support the Exchange's continued investment in this 
optional premium offering. The proposed $5,490 installation fee for a 
Nasdaq-provided Liquid-Cooled Cabinet is reasonable because it is 
consistent with the existing NY11-4/-5 installation fee for a standard 
Cabinet under Rule General 8, Section 1(a) and because installation of 
a Liquid-Cooled Cabinet is more involved than installation of a 
traditional air-cooled cabinet due to the specialized infrastructure 
and coordination required within the dedicated NY11-5 liquid-cooling 
environment. The proposed $2,500 installation fee for a customer-
provided Liquid-Cooled Cabinet is reasonable because it applies only 
where the customer provides the cabinet and reflects the separate 
installation work associated with making the customer-provided cabinet 
available for use

[[Page 61482]]

within that specialized, dedicated NY11-5 liquid-cooling environment.
    The proposed Liquid-Cooled Cabinet Power installation fees are 
reasonable because they apply to the initial provisioning of Liquid-
Cooled Cabinet Power and reflect the specialized infrastructure, 
configuration, and dedicated capacity associated with making the 
service available to a customer. The proposed ongoing monthly fees for 
Liquid-Cooled Cabinet Power are reasonable because they reflect the 
continuing availability of enhanced liquid-cooling functionality, 
specialized infrastructure, and capacity throughout the customer's 
selected commitment term.
    The Exchange believes that the proposed tiered pricing is 
reasonable because it offers customers lower installation and monthly 
rates when they elect longer commitment terms. Longer-term commitments 
provide the Exchange with greater certainty regarding use of the 
specialized infrastructure and shared capacity required to support 
Liquid-Cooled Cabinets, and the proposed discounts are designed to 
encourage such commitments while allowing customers to choose the term 
that best fits their business needs.
    The Exchange believes that the proposed fees are equitably 
allocated and not unfairly discriminatory because they will apply 
uniformly to all similarly situated customers that elect the same 
Liquid-Cooled Cabinet and Liquid-Cooled Cabinet Power options in NY11-
5. Customers that choose a Nasdaq-provided Liquid-Cooled Cabinet will 
be assessed the same Nasdaq-provided cabinet installation fee, and 
customers that choose a customer-provided Liquid-Cooled Cabinet will be 
assessed the same customer-provided cabinet installation fee. The 
service is optional, and customers that do not require liquid-cooling 
functionality may continue to use the Exchange's existing co-location 
cabinet and power offerings, as applicable.

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 fees apply only to 
an optional premium co-location service. Customers are not required to 
purchase Liquid-Cooled Cabinet installation, Liquid-Cooled Cabinet 
Power Installation or Liquid-Cooled Cabinet Power to connect to the 
Exchange or to receive co-location services, and customers will 
continue to have existing options for cabinet and power offerings to 
satisfy their business needs.
    The Exchange believes that the proposal may enhance competition by 
expanding the range of optional co-location services available to 
customers, including customers that seek infrastructure options 
designed to support increasingly power-dense equipment. The proposal 
also gives customers flexibility to choose between a Nasdaq-provided 
Liquid-Cooled Cabinet and a customer-provided Liquid-Cooled Cabinet 
based on their business and infrastructure needs. The proposed fee 
structure reflects the value of the enhanced functionality, specialized 
infrastructure, customer choice, and dedicated capacity associated with 
Liquid-Cooled Cabinets, Liquid-Cooled Cabinet Power Installation and 
Liquid-Cooled Cabinet Power, and customers remain free to use existing 
cabinet and power offerings to satisfy their business needs. 
Accordingly, the Exchange does not believe that the proposal will 
impose any burden on intermarket or intramarket competition.
