(a) The number of total service territory square miles counts once only a square mile that includes both electric and natural gas services, and thus does not represent the combined total square mileage of electric and

natural gas service territories.

(b) The total service territory population counts once only an individual who lives in a region that includes both electric and natural gas services, and thus does not represent the combined total population of electric and

natural gas service territories.

(c) The number of total customers counts once only a customer who is both an electric and a natural gas customer, and thus does not represent the combined total of electric customers and natural gas customers.

The Utility Registrants have the necessary authorizations to perform their current business of providing regulated electric and natural gas distribution services in the various municipalities and territories in
which they now supply such services. These authorizations include charters, franchises, permits, and certificates of public convenience issued by local and state governments and state utility commissions.
ComEd's,  BGE's  (gas),  Pepco  DC's,  and ACE's  rights  are  generally  non-exclusive  while  PECO's,  BGE's  (electric),  Pepco  MD's,  and  DPL's  rights  are  generally  exclusive.  Certain  authorizations  are
perpetual while others have varying expiration dates. The Utility Registrants anticipate working with the appropriate governmental bodies to extend or replace the authorizations prior to their expirations.
The current ComEd Franchise Agreement with the City of Chicago (the City) has been in force since 1992. The Franchise Agreement became terminable on one year notice as of December 31, 2020.  It
now  continues  in  effect  indefinitely  unless  and  until  either  party  issues  a  notice  of  termination,  effective  one  year  later,  or  it  is  replaced  by  mutual  agreement  with  a  new  franchise  agreement  between
ComEd and the City. If either party terminates and no new agreement is reached between the parties, the parties could continue with ComEd providing electric services within the City with no franchise
agreement in place. The City also has an option to terminate and purchase the ComEd system (“municipalize”), which also requires one year notice. Neither party has issued a notice of termination at this
time, the City has not exercised its municipalization option, and no new agreement has become effective. ComEd is in the process of pursuing a new agreement with the City.

While  Exelon  and  ComEd  cannot  predict  the  ultimate  outcome,  fundamental  changes  in  the  agreement  or  other  adverse  actions  affecting  ComEd’s  business  in  the  City  would  require  changes  in  their
business planning models

and  operations  and  could  have  a  material  adverse  impact  on  Exelon’s  and  ComEd’s  consolidated  financial  statements.  If  the  City  were  to  disconnect  from  the  ComEd  system,  ComEd  would  seek  full
compensation for the business and its associated property taken by the City, as well as for all damages resulting to ComEd and its system. ComEd would also seek appropriate compensation for stranded
costs with FERC.

Utility Regulations

State  utility  commissions  regulate  the  Utility  Registrants'  electric  and  gas  distribution  rates  and  service,  issuances  of  certain  securities,  and  certain  other  aspects  of  the  business.  The  following  table
outlines the state commissions responsible for utility oversight:

Registrant
ComEd
PECO
BGE
Pepco
DPL
ACE

Commission
ICC
PAPUC
MDPSC
DCPSC/MDPSC
DEPSC/MDPSC
NJBPU

The Utility Registrants are public utilities under the Federal Power Act subject to regulation by FERC related to transmission rates and certain other aspects of the utilities' business. The U.S. Department
of Transportation also regulates pipeline safety and other areas of gas operations for PECO, BGE, and DPL. The U.S. Department of Homeland Security (Transportation Security Administration) provided
new security directives in 2021 that regulate cyber risks for certain gas distribution operators. Additionally, the Utility Registrants are subject to NERC mandatory reliability standards, which protect the
nation's bulk power system against potential disruptions from cyber and physical security breaches.

Seasonality Impacts on Delivery Volumes

The Utility Registrants' electric distribution volumes are generally higher during the summer and winter months when temperature extremes create demand for either summer cooling or winter heating. For
PECO, BGE, and DPL, natural gas distribution volumes are generally higher during the winter months when cold temperatures create demand for winter heating.

ComEd, BGE, Pepco, DPL Maryland, and ACE have electric distribution decoupling mechanisms and BGE has a natural gas decoupling mechanism that eliminate the favorable and unfavorable impacts of
weather and customer usage patterns on electric distribution and natural gas delivery volumes. As a result, ComEd's, BGE's, Pepco's, DPL Maryland's, and ACE's electric distribution revenues and BGE's
natural gas distribution revenues are not materially impacted by delivery volumes. PECO's and DPL Delaware's electric distribution revenues and natural gas distribution revenues are impacted by delivery
volumes.

Electric and Natural Gas Distribution Services

The Utility Registrants are allowed to recover reasonable costs and fair and prudent capital expenditures associated with electric and natural gas distribution services and earn a return on those capital
expenditures, subject to commission approval. ComEd recovers costs through a performance-based rate formula. ComEd is required to file an update to the performance-based rate formula on an annual
basis.  On  September  15,  2021,  Illinois  passed  CEJA,  which  contains  requirements  for  ComEd  to  transition  away  from  the  performance-based  rate  formula  by  the  end  of  2022  and  would  allow  for  the
submission  of  either  a  general  rate  or  multi-year  rate  plan.  On  February  3,  2022,  the  ICC  approved  a  tariff  that  establishes  the  process  under  which  ComEd  will  reconcile  its  2022  and  2023  rate  year
revenue requirements with actual costs. ComEd's electric distribution costs are currently recovered through a multi-year rate plan with case proceedings as filed with the ICC. PECO's and DPL's electric
and gas distribution costs and ACE's electric distribution costs have generally been recovered through rate case proceedings, with PECO utilizing a fully projected future test year while DPL and ACE
utilize a historical test year. BGE’s electric and gas distribution costs and Pepco’s and DPL Maryland's electric distribution costs are currently recovered through multi-year rate case proceedings, as the
MDPSC and the DCPSC allow utilities to file multi-year rate plans. In certain instances, the Utility Registrants use specific recovery mechanisms

Table of Contents

as approved by their respective regulatory agencies. See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information.

ComEd,  Pepco,  DPL  and ACE  customers  have  the  choice  to  purchase  electricity,  and  PECO  and  BGE  customers  have  the  choice  to  purchase  electricity  and  natural  gas  from  competitive  electric
generation  and  natural  gas  suppliers.  DPL  customers,  with  the  exception  of  certain  commercial  and  industrial  customers,  do  not  have  the  choice  to  purchase  natural  gas  from  competitive  natural  gas
suppliers. The Utility Registrants remain the distribution service providers for all customers and are obligated to deliver electricity and natural gas to customers in their respective service territories while
charging a regulated rate for distribution service. In addition, the Utility Registrants also retain significant default service obligations to provide electricity to certain groups of customers in their respective
service areas who do not choose a competitive electric generation supplier. PECO, BGE, and DPL also retain significant default service obligations to provide natural gas to certain groups of customers in
their respective service areas who do not choose a competitive natural gas supplier.

For  customers  that  choose  to  purchase  electric  generation  or  natural  gas  from  competitive  suppliers,  the  Utility  Registrants  act  as  the  billing  agent  and  therefore  do  not  record  Operating  revenues  or
Purchased power and fuel expense related to the electricity and/or natural gas. For customers that choose to purchase electric generation or natural gas from a Utility Registrant, the Utility Registrants are
permitted to recover the electricity and natural gas procurement costs from customers without mark-up or with a slight mark-up and therefore record the amounts in Operating revenues and Purchased
power and fuel expense. As a result, fluctuations in electricity or natural gas sales and procurement costs have no significant impact on the Utility Registrants’ Net income.

See ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, Results of Operations and Note 3 — Regulatory Matters of the Combined
Notes to Consolidated Financial Statements for additional information regarding electric and natural gas distribution services.

Procurement of Electricity and Natural Gas

Exelon does not generate the electricity it delivers. The Utility Registrants' electric supply for its customers is primarily procured through contracts as directed by their respective state laws and regulatory
commission actions. The Utility Registrants procure electricity supply from various approved bidders or from purchases on the PJM operated markets.

PECO's, BGE’s, and DPL's natural gas supplies are purchased from a number of suppliers for terms that currently do not exceed three years. PECO, BGE, and DPL each have annual firm transportation
contracts of 445,000 mmcf, 268,000 mmcf, and 44,000 mmcf, respectively, for delivery of gas. To supplement gas transportation and supply at times of heavy winter demands and in the event of temporary
emergencies, PECO, BGE, and DPL have available storage capacity from the following sources:

(a) Natural gas from underground storage represents approximately 27%, 42%, and 33% of PECO's, BGE’s, and DPL's 2023-2024 heating season pipeline capacity, respectively.

PECO, BGE, and DPL have long-term interstate pipeline contracts and also participate in the interstate markets by releasing pipeline capacity or bundling pipeline capacity with gas for off-system sales.
Off-system gas sales are low-margin direct sales of gas to wholesale suppliers of natural gas. Earnings from these activities are shared between the utilities and customers. PECO, BGE, and DPL make
these sales as part of a program to balance its supply and cost of natural gas. The off-system gas sales are not material to PECO, BGE, and DPL.

See ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK, Commodity Price Risk (All Registrants), for additional information regarding Utility Registrants' contracts to
procure electric supply and natural gas.

Energy Efficiency Programs

The  Utility  Registrants  are  generally  allowed  to  recover  costs  associated  with  the  energy  efficiency  and  demand  response  programs  they  offer.  Each  commission  approved  program  seeks  to  meet
mandated  electric  consumption  reduction  targets  and  implement  demand  response  measures  to  reduce  peak  demand.  The  programs  are  designed  to  meet  standards  required  by  each  respective
regulatory agency.

ComEd, with limited exceptions, earns a return on its energy efficiency costs through a regulatory asset. ACE earns a return on most of its energy efficiency and demand response program costs through a
regulatory asset. Historically, BGE, Pepco Maryland, and DPL Maryland deferred most of their energy efficiency program costs to a regulatory asset and either deferred most of their demand response
program costs to a regulatory asset or capitalized them. Beginning in 2024, BGE, Pepco, and DPL will begin deferring less energy efficiency and demand response program costs to a regulatory asset.
See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information.

Capital Investment

The  Utility  Registrants'  businesses  are  capital  intensive  and  require  significant  investments,  primarily  in  electric  transmission  and  distribution  and  natural  gas  transportation  and  distribution  facilities,  to
ensure the adequate capacity, reliability, and efficiency of their systems. See ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS,
Liquidity and Capital Resources, for additional information regarding projected 2024 capital expenditures.

Transmission Services

Under FERC’s open access transmission policy, the Utility Registrants, as owners of transmission facilities, are required to provide open access to their transmission facilities under filed tariffs at cost-
based rates approved by FERC. The Utility Registrants and their affiliates are required to comply with FERC’s Standards of Conduct regulation governing the communication of non-public transmission
information between the transmission owner’s employees and wholesale merchant employees.

PJM is the regional grid operator and operates pursuant to FERC-approved tariffs. PJM is the transmission provider under, and the administrator of, the PJM Tariff. PJM operates the PJM energy, capacity,
and other markets, and, through central dispatch, controls the day-to-day operations of the bulk power system for the region. The Utility Registrants are members of PJM and provide regional transmission
service  pursuant  to  the  PJM  Tariff.  The  Utility  Registrants  and  the  other  transmission  owners  in  PJM  have  turned  over  control  of  certain  of  their  transmission  facilities  to  PJM,  and  their  transmission
systems  are  under  the  dispatch  control  of  PJM.  Under  the  PJM  Tariff,  transmission  service  is  provided  on  a  region-wide,  open-access  basis  using  the  transmission  facilities  of  the  PJM  transmission
owners.

The Utility Registrants' transmission rates are based on a FERC approved formula and established on an annual basis as shown below:

April 2006
April 2006

Following the separation on February 1, 2022, Exelon is now a transmission and distribution company, focused on delivering electricity and natural gas service to our customers and communities. Exelon's
businesses remain focused on maintaining industry leading operational excellence, meeting or exceeding their financial commitments, ensuring timely recovery on investments to enable customer benefits,
supporting clean energy

10

Table of Contents

policies including those that advance our jurisdictions' clean energy targets, and continued commitment to corporate responsibility.

Exelon’s strategy is to improve reliability and operations, enhance the customer experience, and advance clean and affordable energy choices, while ensuring ratemaking mechanisms provide the utilities
fair financial returns. The jurisdictions in which Exelon has operations have set some of the nation's leading clean energy targets and our strategy is to enable that future for all our stakeholders. The Utility
Registrants invest in rate base that supports service to our customers and the community, including investments that sustain and improve reliability and resiliency and that enhance the service experience
of  our  customers.  The  Utility  Registrants  make  these  investments  prudently  at  a  reasonable  cost  to  customers.  Exelon  seeks  to  leverage  its  scale  and  expertise  across  the  utilities  platform  through
enhanced standardization and sharing of resources and best practices to achieve improved operational and financial results.

Management continually evaluates growth opportunities aligned with Exelon’s businesses, assets, and markets, leveraging Exelon’s expertise in those areas and offering sustainable returns.

The  Utility  Registrants  anticipate  investing  approximately  $35  billion  over  the  next  four  years  in  electric  and  natural  gas  infrastructure  improvements  and  modernization  projects,  including  smart  grid
technology, storm hardening, advanced reliability technologies, and transmission projects, which is projected to result in an increase to current rate base of approximately $19 billion by the end of 2027.
These investments provide greater reliability, improved service for our customers, increased capacity to accommodate new technologies and support a cleaner grid, and a stable return for the company.

In August 2021, Exelon announced a Path to Clean goal to collectively reduce its operations-driven GHG emissions 50% by 2030 against a 2015 baseline and to reach net zero operations-driven GHG
emissions by 2050, while supporting customers and communities in achieving their GHG reduction goals (Path to Clean). Exelon's quantitative goals include its Scope 1 and 2 GHG emissions, with the
exception of Scope 2 emissions associated with system losses of electric power delivered to customers ("line losses"), and build upon Exelon's long-standing commitment to reducing our GHG emissions.
Exelon's Path to Clean efforts extend beyond these quantitative goals to include efforts such as customer energy efficiency programs, which support reductions in customers' direct emissions and have the
potential to reduce Exelon's Scope 3 emissions and Scope 2 line losses as well. See ITEM 1. BUSINESS — Environmental Matters and Regulation — Climate Change for additional information.

Various  market,  financial,  regulatory,  legislative,  and  operational  factors  could  affect  Exelon's  success  in  pursuing  its  strategies.  Exelon continues to assess infrastructure, operational, policy, and legal
solutions to these issues. See ITEM 1A. RISK FACTORS for additional information.

Employees

The Registrants strive to create a workplace culture that promotes and embodies diversity, inclusion, innovation, and safety for their employees. In order to provide the services and products that their
customers expect, the Registrants aspire to create teams that reflect the diversity of the communities that the Registrants serve. Therefore, the Registrants take steps to attract and retain highly qualified
and  diverse  talent  and  seek  to  create  hiring  and  promotion  practices  that  are  equitable  and  neutralize  any  bias,  including  unconscious  bias.  The  Registrants  provide  growth  opportunities,  competitive
compensation and benefits, and a variety of training and development programs. The Registrants are committed to helping all employees grow their skills and careers largely through numerous training
opportunities, mentorship programs, continuous feedback and development discussions, and evaluations. Employees are encouraged to thrive outside the workplace as well. The Registrants provide a full
suite of wellness benefits targeted at supporting work-life balance, physical, mental and financial health, and industry-leading paid leave policies.

The  Registrants  typically  conduct  an  employee  engagement  survey  every  other  year  to  help  identify  organizational  strengths  and  areas  of  opportunity  for  growth. The  survey  results  are  reviewed  with
senior management and the Exelon Board of Directors.

Environmental Matters and Regulation

The Registrants are subject to comprehensive and complex environmental legislation and regulation at the federal, state, and local levels, including requirements relating to climate change, air and water
quality, solid and hazardous waste, and impacts on species and habitats.

The Exelon Board of Directors is responsible for overseeing the management of environmental matters. Exelon has a management team to address environmental compliance and strategy, including the
CEO; the Senior Vice President and Chief Strategy and Sustainability Officer; as well as senior management of the Utility Registrants. Performance of those individuals directly involved in environmental
compliance and strategy is reviewed and affects compensation as part of the annual individual performance review process. The Audit and Risk Committee oversees compliance with environmental laws
and regulations, including environmental risks related to Exelon's operations and facilities, as well as SEC disclosures related to environmental matters. Exelon's Corporate Governance Committee has the
authority to oversee Exelon’s climate change and sustainability policies and programs, as discussed in further detail below. The respective Boards of the Utility Registrants oversee environmental issues
related to these companies. The Exelon Board of Directors has general oversight responsibilities for ESG matters, including strategies and efforts to protect and improve the quality of the environment.

Climate Change

As detailed below, the Registrants face climate change mitigation and transition risks as well as adaptation risks. Mitigation and transition risks include changes to the energy systems as a result of new
technologies, changing customer expectations and/or voluntary GHG goals, as well as local, state or federal regulatory requirements intended to reduce GHG emissions. Adaptation risk refers to risks to
the Registrants' facilities or operations that may result from changes to the physical climate and environment, such as changes to temperature, weather patterns and sea level.

Climate Change Mitigation and Transition

The Registrants support comprehensive federal climate legislation that addresses the urgent need to substantially reduce national GHG emissions while providing appropriate protections for consumers,
businesses, and the economy. In the absence of comprehensive federal climate legislation, Exelon supports the EPA moving forward with meaningful regulation of GHG emissions under the Clean Air Act.

The Registrants currently are subject to, and may become subject to additional, federal and/or state legislation and/or regulations addressing GHG emissions. The direct (Scope 1) GHG emission sources
associated with the Registrants include sulfur hexafluoride (SF6) leakage from electric transmission and distribution operations, fossil fuel combustion in motor vehicles and refrigerant leakage from chilling
and cooling equipment. In addition, PECO, BGE, and DPL, as distributors of natural gas, have natural gas (methane) leakage on the natural gas systems. The Registrants also have indirect (Scope 2 and
3) emissions associated with the production of the

13

Table of Contents

electricity they consume and deliver, and indirect (Scope 3) emissions associated with the production of natural gas they deliver and consumer use of such natural gas.

Exelon uses definitions and protocols provided by the World Resources Institute for its GHG inventory. In 2022, Exelon's Scope 1 and 2 GHG emissions, were just over 5.7 million metric tons carbon
dioxide equivalent using the World Resources Institute Corporate Standard Market-based accounting. Of these emissions, 0.5 million metric tons are considered to be operations-driven and in more direct
control of our employees and processes. The majority of these operations-driven emissions are fugitive emissions from the gas delivery systems of Registrants PECO, BGE, and DPL. The remaining 5.2
million metric tons, approximately 91%, are the indirect emissions associated with the electric transmission and distribution system and primarily consists of losses resulting from the Utility Registrant's
delivery of electricity to their customers (line losses). These emissions are driven primarily by customer demand for electricity and the mix of generation assets supplying energy to the electric grid. The
Registrants do not own generation and must comply with applicable legal and regulatory requirements governing procurement of electricity for delivery to retail customers and use of the system to support
other transmission transactions. However, the Registrants do engage in efforts that help to reduce these emissions, including customer programs to drive customer energy efficiency, to help manage peak
demands, and to enable distributed solar generation.

In August 2021, Exelon announced a Path to Clean goal to collectively reduce its operations-driven GHG emissions 50% by 2030 against a 2015 baseline, and to reach net zero operations-driven GHG
emissions by 2050, while also supporting customers and communities to achieve their clean energy and emissions reduction goals. Exelon’s quantitative goals include its Scope 1 and 2 GHG emissions
with the exception of Scope 2 line losses, and build upon Exelon's long-standing commitment to reducing our GHG emissions. Exelon's activities in support of the Path to Clean goal will include efficiency
and clean electricity for operations, vehicle fleet electrification, equipment and processes to reduce sulfur hexafluoride (SF6) leakage, investments in natural gas infrastructure to minimize methane leaks
and  increase  safety  and  reliability,  and  investment  and  collaboration  to  develop  new  technologies.  Beyond  2030,  Exelon  recognizes  that  technology  advancement  and  continued  policy  support  will  be
needed to ensure achievement of Net-Zero by 2050. Exelon is laying the groundwork by partnering with national labs, universities and research consortia to research, develop, and pilot clean technologies
that will be needed, as well as working with our states, jurisdictions and policy makers to understand the scope and scale of energy transformation, and needed policies and incentives, that will be needed
to reach local ambitions for GHG emissions reductions. The Utility Registrants are also supporting customers and communities to achieve their clean energy and emissions goals through significant energy
efficiency programs. During 2024 - 2027, estimated customer program energy efficiency investments across the Utility Registrants total $5.1 billion. These programs enable customer savings through home
energy audits, lighting discounts, appliance recycling, home improvement rebates, equipment upgrade incentives and innovative programs like smart thermostats and combined heat and power programs.

As an energy delivery company, Exelon can play a role in helping to reduce GHG emissions in its service territories. In connecting end users of energy to electric and gas supply, Exelon can leverage its
assets  and  customer  interface  to  help  support  efficient  use  of  lower  emitting  resources  as  they  become  available.  Electrification,  where  feasible,  for  transportation,  buildings,  and  industry  coupled  with
simultaneous  decarbonization  of  electric  generation,  can  be  an  important  means  to  reduce  emissions.  Exelon  is  advocating  for  public  policy  supportive  of  vehicle  electrification,  investing  in  enabling
infrastructure and technology, and supporting customer education and adoption. In addition, the Utility Registrants have a goal to electrify 30% of their own vehicle fleet by 2025, increasing to 50% by 2030.
Clean fuels and other emerging technologies can also support the transition, lessen the strain on electric system expansion, and support energy system resiliency. Exelon, and its registrants PECO, BGE,
and  DPL  that  own  gas  distribution  assets,  are  also  continuing  to  explore  these  other  decarbonization  opportunities,  supporting  pilots  of  emerging  energy  technologies  and  clean  fuels  to  support  both
operational and customer-driven emissions reductions. The energy transition may present challenges for the Utility Registrants and their service territories. Exelon believes its market and business model
could be significantly affected by the transition of the energy system, such as through an increased electric load and decreased demand for natural gas, potentially accompanied by changes in technology,
customer expectations, and/or regulatory structures. See ITEM 1A. RISK FACTORS. The Registrants are potentially affected by emerging technologies that could over time affect or transform the energy
industry.

Climate Change Adaptation

14

Table of Contents

The Registrants' facilities and operations are subject to the impacts of global climate change. Long-term shifts in climactic patterns, such as sustained higher temperatures and sea level rise, may present
challenges for the Registrants and their service territories. Exelon believes its operations could be significantly affected by the physical risks of climate change. See ITEM 1A. RISK FACTORS for additional
information related to the Registrants' risks associated with climate change.

The Registrants' assets undergo seasonal readiness efforts to ensure that they are prepared for the weather projections for the summer and winter months. The Registrants consider and review national
climate assessments to inform their planning. Each of the Utility Registrants also has well established system recovery plans and is investing in its systems to install advanced equipment and reinforce the
local electric system, making it more weather resistant and less vulnerable to anticipated storm damage.

International  Climate  Change  Agreements. At  the  international  level,  the  United  States  is  a  party  to  the  United  Nations  Framework  Convention  on  Climate  Change  (UNFCCC).  The  Parties  to  the
UNFCCC adopted the Paris Agreement at the 21st session of the UNFCCC Conference of the Parties (COP 21) on December 12, 2015. Under the Agreement, which became effective on November 4,
2016, the parties committed to try to limit the global average temperature increase and to develop national GHG reduction commitments. On November 4, 2020, the United States formally withdrew from
the Paris Agreement, but on January 20, 2021, President Biden accepted the Agreement, which resulted in the United States’ formal re-entry on February 19, 2021. The United States has set an economy-
wide target of reducing its net GHG emissions by 50-52% below 2005 levels by 2030. On November 11, 2022, at the UNFCCC Conference of the Parties (COP 27), President Biden recommitted the U.S.
to these goals and detailed the significant domestic climate actions the U.S. had taken to spur a new era of clean American manufacturing, enhance energy security, and drive down the costs of clean
energy for consumers in the U.S. and around the world.

Federal Climate Change Legislation and Regulation. On August 16, 2022, President Biden signed the Inflation Reduction Act (IRA), which, among other things, aims to reduce U.S. carbon emissions
and promote economic development through investments in clean and renewable energy projects. The consumer-facing clean energy tax credits created or expanded by the IRA are intended to drive rapid
adoption of energy efficiency, electric transportation, and solar energy which would require Exelon's utilities to expand and modernize infrastructure, systems and services to integrate and optimize these
resources.

State Climate Change Legislation and Regulation. A number of states in which the Registrants operate have state and regional programs to reduce GHG emissions and renewable and other portfolio
standards, which impact the power sector. See discussion below for additional information on renewable and other portfolio standards.

Certain  northeast  and  mid-Atlantic  states  (Connecticut,  Delaware,  Maine,  Maryland,  Massachusetts,  New  Hampshire,  New  Jersey,  New  York,  Pennsylvania,  Rhode  Island,  Vermont,  Virginia)  currently
participate in the RGGI. The program requires most fossil fuel-fired power plant owners and operators in the region to hold allowances, purchased at auction, for each ton of CO2 emissions. Non-emitting
resources do not have to purchase or hold these allowances. Pennsylvania joined RGGI in April 2022.

Broader state programs impact other sectors as well, such as the District of Columbia's Clean Energy DC Omnibus Act and cross-sector GHG reduction plans, which resulted in recent requirements for
Pepco  to  develop  5-year  and  30-year  decarbonization  programs  and  strategies.  Maryland  expects  to  meet  and  exceed  the  mandate  set  in  the  Greenhouse  Gas  Emissions  Reduction Act  to  reduce
statewide GHG emissions 40% (from 2006 levels) by 2030, and the state’s Climate Solutions Now Act of 2022 further updates requirements with a proposal to reduce emissions 60% (from 2006 levels) by
2031. New Jersey accelerated its goals through Executive Order 274, which establishes an interim goal of 50% reductions below 2006 levels by 2030 and affirms its goal of achieving 80% reductions by
2050 and includes programs to drive greater amounts of electrified transportation. Delaware's Climate Change Solutions Act established in August 2023 sets a statewide GHG emissions reduction goal of
50% by Jan 1, 2030 and a net-zero GHG emissions goal by Jan 1, 2050, on a net basis as compared to a 2005 baseline. Illinois’ climate bill, CEJA, establishes decarbonization requirements for the state to
transition  to  100%  clean  energy  by  2050  and  supports  programs  to  improve  energy  efficiency,  manage  energy  demand,  attract  clean  energy  investment  and  accelerate  job  creation.  See  Note  3  —
Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information on CEJA.

Table of Contents

The Registrants cannot predict the nature of future regulations or how such regulations might impact future financial statements.

Renewable and Clean Energy Standards. Each of the states where Exelon operates have adopted some form of renewable or clean energy procurement requirement. These standards impose varying
levels of mandates for procurement of renewable or clean electricity (the definition of which varies by state) and/or energy efficiency. These are generally expressed as a percentage of annual electric load,
often increasing by year. The Utility Registrants comply with these various requirements through acquiring sufficient bundled or unbundled credits such as RECs, CMCs, or ZECs, or paying an alternative
compliance payment, and/or a combination of these compliance alternatives. The Utility Registrants are permitted to recover from retail customers the costs of complying with their state RPS requirements,
including the procurement of RECs or other alternative energy resources. See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information.

Other Environmental Regulation

Water Quality

Under the federal Clean Water Act, NPDES permits for discharges into waterways are required to be obtained from the EPA or from the state environmental agency to which the permit program has been
delegated, and permits must be renewed periodically. Certain of Exelon's facilities discharge water into waterways and are therefore subject to these regulations and operate under NPDES permits.

Under Clean Water Act Section 404 and state laws and regulations, the Registrants may be required to obtain permits for projects involving dredge or fill activities in waters of the United States.

Where Registrants’ facilities are required to secure a federal license or permit for activities that may result in a discharge to covered waters, they may be required to obtain a state water quality certification
under Clean Water Act section 401.

Solid and Hazardous Waste and Environmental Remediation

CERCLA  provides  for  response  and  removal  actions  coordinated  by  the  EPA  in  the  event  of  threatened  releases  of  hazardous  substances  and  authorizes  the  EPA  either  to  clean  up  sites  at  which
hazardous  substances  have  created  actual  or  potential  environmental  hazards  or  to  order  persons  responsible  for  the  situation  to  do  so.  Under  CERCLA,  generators  and  transporters  of  hazardous
substances, as well as past and present owners and operators of hazardous waste sites, are strictly, jointly and severally liable for the cleanup costs of hazardous waste at sites, many of which are listed by
the  EPA  on  the  National  Priorities  List  (NPL).  These  PRPs  can  be  ordered  to  perform  a  cleanup,  can  be  sued  for  costs  associated  with  an  EPA-directed  cleanup,  may  voluntarily  settle  with  the  EPA
concerning  their  liability  for  cleanup  costs,  or  may  voluntarily  begin  a  site  investigation  and  site  remediation  under  state  oversight.  Most  states  have  also  enacted  statutes  that  contain  provisions
substantially similar to CERCLA. Such statutes apply in many states where the Registrants currently own or operate, or previously owned or operated, facilities, including Delaware, Illinois, Maryland, New
Jersey,  and  Pennsylvania  and  the  District  of  Columbia.  In  addition,  RCRA  governs  treatment,  storage  and  disposal  of  solid  and  hazardous  wastes  and  cleanup  of  sites  where  such  activities  were
conducted.

The Registrants’ operations have in the past, and may in the future, require substantial expenditures in order to comply with these Federal and state environmental laws. Under these laws, the Registrants
may  be  liable  for  the  costs  of  remediating  environmental  contamination  of  property  now  or  formerly  owned  by  them  and  of  property  contaminated  by  hazardous  substances  generated  by  them.  The
Registrants own or lease a number of real estate parcels, including parcels on which their operations or the operations of others may have resulted in contamination by substances that are considered
hazardous under environmental laws. The Registrants and their subsidiaries are, or could become in the future, parties to proceedings initiated by the EPA, state agencies, and/or other responsible parties
under CERCLA and RCRA or similar state laws with respect to a number of sites or may undertake to investigate and remediate sites for which they may be subject to enforcement actions by an agency or
third-party.

ComEd’s and PECO’s environmental liabilities primarily arise from contamination at former MGP sites, which were operated by ComEd's and PECO's predecessor companies. ComEd, pursuant to an ICC
order, and PECO, pursuant to settlements of natural gas distribution rate cases with the PAPUC, have an on-going process to recover certain environmental remediation costs of the MGP sites through a
provision within customer rates. BGE, Pepco, DPL, and ACE do not have material contingent liabilities relating to MGP sites. The amount to be

16

Table of Contents

expended  in  2024  for  activities  associated  with  the  environmental  investigation  and  remediation  related  to  contamination  at  former  MGP  sites  and  other  gas  purification  sites  is  estimated  to  be
approximately $36 million which consists primarily of $25 million at ComEd.

As of December 31, 2023, the Registrants have established appropriate contingent liabilities for environmental remediation requirements. In addition, the Registrants may be required to make significant
additional expenditures not presently determinable for other environmental remediation costs.

See  Note  3  —  Regulatory  Matters  and  Note  18  —  Commitments  and  Contingencies  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  regarding  the  Registrants’
environmental matters, remediation efforts, and related impacts to the Registrants’ Consolidated Financial Statements.

Each  of  the  Registrants  operates  in  a  complex  market  and  regulatory  environment  that  involves  significant  risks,  many  of  which  are  beyond  that  Registrant’s  direct  control.  Such  risks,  which  could
negatively affect one or more

20

Table of Contents

of  the  Registrants’  consolidated  financial  statements,  are  captured  below.  Although  the  risks  are  generally  organized  by  category  and  separately  described,  many  of  these  risks  are  interrelated.
Additionally, the risks should be considered holistically with other information included in this filing and future filings with the SEC.

Risks related to market and financial factors primarily include:

•

•

•

the demand for electricity, reliability of service, and affordability in the markets where the Utility Registrants conduct their business,

the ability of the Utility Registrants to operate their respective transmission and distribution assets, their ability to access capital markets, and the impacts on their results of operations, financial
condition or liquidity/cash flows due to public health crises, epidemics or pandemics, and

emerging technologies and business models, including those related to climate change mitigation and transition to a low carbon economy.

Risks related to legislative, regulatory, and legal factors primarily include changes to, and compliance with, the laws and regulations that govern:

•

•

•

utility regulatory business models,

energy, environmental, and climate policy, and

tax policy.

Risks related to operational factors primarily include:

•

•

•

changes in the global climate could produce extreme weather events, which could put the Registrant’s facilities at risk, and such changes could also affect the levels and patterns of demand for
energy and related services,

the ability of the Utility Registrants to maintain the reliability, resiliency, and safety of their energy delivery systems, which could affect their ability to deliver energy to their customers and affect
their operating costs, and

physical and cyber security risks for the Utility Registrants as the owner-operators of transmission and distribution facilities.

Risks related to the separation primarily include:

•

•

challenges to achieving the benefits of separation and

performance by Exelon and Constellation under the transaction agreements, including indemnification responsibilities.

There may be further risks and uncertainties that are not presently known or that are not currently believed to be material that could negatively affect the Registrants' consolidated financial statements in
the future.

Risks Related to Market and Financial Factors

The Registrants are potentially affected by emerging technologies that could over time affect or transform the energy industry (All Registrants).

Advancements  in  power  generation  technology,  including  commercial  and  residential  solar  generation  installations  and  commercial  micro  turbine  installations,  are  improving  the  cost-effectiveness  of
customer  self-supply  of  electricity.  Improvements  in  energy  storage  technology,  including  batteries  and  fuel  cells,  could  also  better  position  customers  to  meet  their  around-the-clock  electricity
requirements. Improvements in energy efficiency of lighting, appliances, equipment and building materials will also affect energy consumption by customers. Changes in power generation, storage, and use
technologies could have significant effects on customer behaviors and their energy consumption.

21

Table of Contents

These developments could affect levels of customer-owned generation, customer expectations, and current business models and make portions of the Utility Registrants' transmission and/or distribution
facilities uneconomic prior to the end of their useful lives. Increasing pressure from both the private and public sectors to take actions to mitigate climate change could also push the speed and nature of this
transition. These factors could affect the Registrants’ consolidated financial statements through, among other things, increased Operating and maintenance expenses, increased capital expenditures, and
potential asset impairment charges or accelerated depreciation over shortened remaining asset useful lives.

Market performance and other factors could decrease the value of employee benefit plan assets and could increase the related employee benefit plan obligations, which then
could require significant additional funding (All Registrants).

Disruptions in the capital markets and their actual or perceived effects on particular businesses and the greater economy could adversely affect the value of the investments held within Exelon’s employee
benefit plan trusts. The asset values are subject to market fluctuations and will yield uncertain returns, which could fall below Exelon's projected return rates. A decline in the market value of the pension
and  OPEB  plan  assets  would  increase  the  funding  requirements  associated  with  Exelon’s  pension  and  OPEB  plan  obligations. Additionally,  Exelon’s  pension  and  OPEB  plan  liabilities  are  sensitive  to
changes  in  interest  rates. As  interest  rates  decrease,  the  liabilities  increase,  potentially  increasing  benefit  costs  and  funding  requirements.  Changes  in  demographics,  including  increased  numbers  of
retirements or changes in life expectancy assumptions or changes to Social Security or Medicare eligibility requirements could also increase the costs and funding requirements of the obligations related to
the pension and OPEB plans. See Note 14 — Retirement Benefits of the Combined Notes to Consolidated Financial Statements for additional information.

The Registrants could be negatively affected by unstable capital and credit markets (All Registrants).

The Registrants rely on the capital markets, particularly for publicly offered debt, as well as the banking and commercial paper markets, to meet their financial commitments and short-term liquidity needs.
Disruptions in the capital and credit markets in the United States or abroad could negatively affect the Registrants’ ability to access the capital markets or draw on their respective bank revolving credit
facilities. The banks may not be able to meet their funding commitments to the Registrants if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests
within a short period of time. The inability to access capital markets or credit facilities, and longer-term disruptions in the capital and credit markets because of uncertainty, changing or increased regulation,
reduced alternatives, or failures of significant financial institutions could result in the deferral of discretionary capital expenditures, or require a reduction in dividend payments or other discretionary uses of
cash. In addition, the Registrants have exposure to worldwide financial markets, including Europe, Canada, and Asia. Disruptions in these markets could reduce or restrict the Registrants’ ability to secure
sufficient liquidity or secure liquidity at reasonable terms. As of December 31, 2023, approximately 23%, 10%, and 16% of the Registrants’ available credit facilities were with European, Canadian, and
Asian  banks,  respectively. Additionally,  higher  interest  rates  may  put  pressure  on  the  Registrants’  overall  liquidity  profile,  financial  health  and  impact  financial  results.  See  Note  16  —  Debt  and  Credit
Agreements of the Combined Notes to Consolidated Financial Statements for additional information on the credit facilities.

If any of the Registrants were to experience a downgrade in its credit ratings to below investment grade or otherwise fail to satisfy the credit standards in its agreements with
its  counterparties  or  regulatory  financial  requirements,  it  would  be  required  to  provide  significant  amounts  of  collateral  that  could  affect  its  liquidity  and  could  experience
higher borrowing costs (All Registrants).

The Utility Registrants' operating agreements with PJM and PECO's, BGE's, and DPL's natural gas procurement contracts contain collateral provisions that are affected by their credit rating and market
prices.  If  certain  wholesale  market  conditions  were  to  exist  and  the  Utility  Registrants  were  to  lose  their  investment  grade  credit  ratings  (based  on  their  senior  unsecured  debt  ratings),  they  would  be
required to provide collateral in the forms of letters of credit or cash, which could have a material adverse effect upon their remaining sources of liquidity. PJM collateral posting requirements will generally
increase as market prices rise and decrease as market prices fall. Collateral posting requirements for PECO, BGE, and DPL, with respect to their natural gas supply contracts, will generally increase as
forward market prices fall and decrease as forward market prices rise. If the Utility

22

Table of Contents

Registrants  were  downgraded,  they  could  experience  higher  borrowing  costs  as  a  result  of  the  downgrade. In  addition,  changes  in  ratings  methodologies  by  the  agencies  could  also  have  an  adverse
negative impact on the ratings of the Utility Registrants.

The Utility Registrants conduct their respective businesses and operate under governance models and other arrangements and procedures intended to assure that the Utility Registrants are treated as
separate, independent companies, distinct from Exelon and other Exelon subsidiaries in order to isolate the Utility Registrants from Exelon and other Exelon subsidiaries in the event of financial difficulty at
Exelon or another Exelon subsidiary. These measures (commonly referred to as “ring-fencing”) could help avoid or limit a downgrade in the credit ratings of the Utility Registrants in the event of a reduction
in the credit rating of Exelon. Despite these ring-fencing measures, the credit ratings of the Utility Registrants could remain linked, to some degree, to the credit ratings of Exelon. Consequently, a reduction
in the credit rating of Exelon could result in a reduction of the credit rating of some or all of the Utility Registrants. A reduction in the credit rating of a Utility Registrant could have a material adverse effect
on the Utility Registrant.

See  ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF  OPERATIONS  —  Liquidity  and  Capital  Resources  —  Credit  Matters  and  Cash
Requirements — Security Ratings for additional information regarding the potential impacts of credit downgrades on the Registrants’ cash flows.

The impacts of significant economic downturns or increases in customer rates, could lead to decreased volumes delivered and increased expense for uncollectible customer
balances (All Registrants).

The impacts of significant economic downturns on the Utility Registrants' customers and the related regulatory limitations on residential service terminations for the Utility Registrants, could result in an
increase in the number of uncollectible customer balances and related expense. Further, increases in customer rates, including those related to increases in Purchased power and natural gas prices, could
result in declines in customer usage and lower revenues for the Utility Registrants that do not have decoupling mechanisms.

See ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK for additional information on the Registrants’ credit risk.

The Registrants could be negatively affected by the impacts of weather (All Registrants).

Weather conditions directly influence the demand for electricity and natural gas and affect the price of energy commodities. Temperatures above normal levels in the summer tend to increase summer
cooling electricity demand and revenues, and temperatures below normal levels in the winter tend to increase winter heating electricity and gas demand and revenues. Moderate temperatures adversely
affect the usage of energy and resulting operating revenues at PECO and DPL Delaware. Due to revenue decoupling, operating revenues from electric distribution at ComEd, BGE, Pepco, DPL Maryland,
and ACE and gas distribution at BGE are not affected by abnormal weather.

Extreme weather conditions or damage resulting from storms could stress the Utility Registrants' transmission and distribution systems, communication systems, and technology,  resulting  in  increased
maintenance and capital costs and limiting each Utility Registrant's ability to meet peak customer demand. First and third quarter financial results, in particular, are substantially dependent on weather
conditions, and could make period comparisons less relevant.

Climate  change  projections  suggest  increases  to  summer  temperature  and  humidity  trends,  as  well  as  more  erratic  precipitation  and  storm  patterns  over  the  long-term  in  the  areas  where  the  Utility
Registrants  have  transmission  and  distribution  assets.  The  frequency  in  which  weather  conditions  emerge  outside  the  current  expected  climate  norms  could  contribute  to  weather-related  impacts
discussed above.

Long-lived assets, goodwill, and other assets could become impaired (All Registrants).

Long-lived assets represent the single largest asset class on the Registrants’ statements of financial position. In addition, Exelon, ComEd, and PHI have material goodwill balances.

23

Table of Contents

The Registrants evaluate the recoverability of the carrying value of long-lived assets to be held and used whenever events or circumstances indicating a potential impairment exist. Factors such as, but not
limited to, the business climate, including current and future energy and market conditions, environmental regulation, and the condition of assets are considered.

ComEd and PHI perform an assessment for possible impairment of their goodwill at least annually or more frequently if an event occurs or circumstances change that would more likely than not reduce the
fair  value  of  the  reporting  units  below  their  carrying  amount.  Regulatory  actions  or  changes  in  significant  assumptions,  including  discount  and  growth  rates,  utility  sector  market  performance  and
transactions, projected operating and capital cash flows for ComEd’s, Pepco’s, DPL’s, and ACE’s business, and the fair value of debt, could potentially result in future impairments of Exelon’s, ComEd's,
and PHI’s goodwill.

An impairment would require the Registrants to reduce the carrying value of the long-lived asset or goodwill to fair value through a non-cash charge to expense by the amount of the impairment. See ITEM
7.  MANAGEMENT'S  DISCUSSION AND ANALYSIS  OF  FINANCIAL  CONDITION AND  RESULTS  OF  OPERATIONS  —  Critical Accounting  Policies  and  Estimates,  Note  7  —  Property,  Plant,  and
Equipment, Note 11 — Asset Impairments, and Note 12 — Intangible Assets of the Combined Notes to the Consolidated Financial Statements for additional information on long-lived asset impairments
and goodwill impairments.

The Registrants could incur substantial costs in the event of non-performance by third-parties under indemnification agreements, or when the Registrants have guaranteed
their performance (All Registrants).

The Registrants have entered into various agreements with counterparties that require those counterparties to reimburse a Registrant and hold it harmless against specified obligations and claims. To the
extent  that  any  of  these  counterparties  are  affected  by  deterioration  in  their  creditworthiness  or  the  agreements  are  otherwise  determined  to  be  unenforceable,  the  affected  Registrant  could  be  held
responsible  for  the  obligations.  Each  of  the  Utility  Registrants  has  transferred  its  former  generation  assets  to  one  or  more  third  parties  and  in  each  case  the  transferee  has  agreed  to  assume  certain
obligations  and  to  indemnify  the  applicable  Utility  Registrant  for  such  obligations.  In  connection  with  the  restructurings  under  which  ComEd,  PECO,  and  BGE  transferred  their  generating  assets  to
Constellation, Constellation assumed certain of ComEd’s, PECO’s, and BGE's rights and obligations with respect to their former generation assets. Further, ComEd, PECO, and BGE have entered into
agreements with third parties under which the third-party agreed to indemnify ComEd, PECO, or BGE for certain obligations related to their respective former generation assets that have been assumed by
Constellation  as  part  of  the  restructuring.  If  Constellation  or  a  transferee  of  one  of  the  Utility  Registrant’s  generation  assets  experienced  events  that  reduced  its  creditworthiness  or  the  indemnity
arrangement  became  unenforceable,  the  applicable  Utility  Registrant  could  be  liable  for  any  existing  or  future  claims.  In  addition,  the  Utility  Registrants  have  residual  liability  under  certain  laws  in
connection with their former generation assets.

The Registrants have issued indemnities to third parties regarding environmental or other matters in connection with purchases and sales of assets, including several of the Utility Registrants in connection
with Constellation's absorption of their former generating assets. The Registrants could incur substantial costs to fulfill their obligations under these indemnities.

The Registrants have issued guarantees of the performance of third parties, which obligate the Registrants to perform if the third parties do not perform. In the event of non-performance by those third
parties, the Registrants could incur substantial cost to fulfill their obligations under these guarantees.

Risks Related to Legislative, Regulatory, and Legal Factors

The  Registrants'  businesses  are  highly  regulated  and  electric  and  gas  revenue  and  earnings  could  be  negatively  affected  by  legislative  and/or  regulatory  actions  (All
Registrants).

Substantial aspects of the Registrants' businesses are subject to comprehensive Federal or state legislation and/or regulation.

The Utility Registrants' consolidated financial statements are heavily dependent on the ability of the Utility Registrants to recover their costs for the retail purchase, transmission, and distribution of power
and natural gas to their customers.

24

Table of Contents

Fundamental  changes  in  laws  or  regulations  or  adverse  legislative  or  regulatory  actions  affecting  the  Registrants’  businesses  would  require  changes  in  their  business  planning  models  and  operations.
Registrants cannot always predict when or whether legislative or regulatory action will occur and may not be able to influence the outcome of legislative or regulatory initiatives.

Changes in the Utility Registrants' respective terms and conditions of service, including their respective rates, along with adoption of new rate structures and constructs, or
establishment of new rate cases, are subject to regulatory approval proceedings and/or negotiated settlements that are at times contentious, lengthy, and subject to appeal,
which lead to uncertainty as to the ultimate result, and which could result in uncertainties in rate case outcomes, and/or introduce time delays in effectuating rate changes (All
Registrants).

The Utility Registrants are required to engage in regulatory approval proceedings as a part of the process of establishing the terms and rates for their respective services, adoption of new rate structures
and constructs or establishment of new rate cases. These proceedings typically involve multiple parties, including governmental bodies and officials, consumer advocacy groups, and various consumers of
energy,  who  have  differing  concerns  but  who  have  the  common  objective  of  limiting  rate  increases  or  even  reducing  rates.  Decisions  are  subject  to  appeal,  potentially  leading  to  additional  uncertainty
associated  with  the  approval  proceedings.  The  potential  duration  of  such  proceedings  creates  a  risk  that  rates  ultimately  approved  by  the  applicable  regulatory  body  may  not  be  sufficient  for  a  Utility
Registrant to recover its costs once the rates become effective. Established rates are also subject to subsequent prudency reviews by state regulators, whereby various portions of rates could be adjusted,
subject  to  refund  or  disallowed,  including  recovery  mechanisms  for  costs  associated  with  the  procurement  of  electricity  or  gas,  credit  losses,  MGP  remediation,  smart  grid  infrastructure,  and  energy
efficiency and demand response programs. In certain instances, the Utility Registrants could agree to negotiated settlements related to various rate matters, customer initiatives, or franchise agreements.
These settlements are subject to regulatory approval. The ultimate outcome and timing of regulatory rate proceedings have a significant effect on the ability of the Utility Registrants to recover their costs or
earn an adequate return.

In addition to potential timing delays, the Registrants also face other uncertainties in rate proceedings that could impact recovery, including not obtaining anticipated allowed rates of return, allowed capital
structures, or allowed return on pension assets, and various other factors.

See Note 3 — Regulatory Matters of the Combined Notes to the Consolidated Financial Statements for additional information.

The  Registrants  could  be  subject  to  higher  costs  and/or  penalties  related  to  mandatory  reliability  standards,  including  the  likely  exposure  of  the  Utility  Registrants  to  the
results of PJM’s RTEP and NERC compliance requirements (All Registrants).

The Utility Registrants as users, owners, and operators of the bulk power transmission system are subject to mandatory reliability standards promulgated by NERC and enforced by FERC. The standards
are based on the functions that need to be performed to ensure the bulk power system operates reliably and are guided by reliability and market interface principles. Compliance with or changes in the
reliability  standards  could  subject  the  Registrants  to  higher  operating  costs  and/or  increased  capital  expenditures.  In  addition,  the  ICC,  PAPUC,  MDPSC,  DCPSC,  DEPSC,  and  NJBPU  impose  certain
distribution  reliability  standards  on  the  Utility  Registrants.  If  the  Utility  Registrants  were  found  in  non-compliance  with  the  Federal  or  state  mandatory  reliability  standards,  they  could  be  subject  to
remediation costs as well as sanctions, which could include substantial monetary penalties.

The Registrants could incur substantial costs to fulfill their obligations related to environmental and other matters (All Registrants).

The Registrants are subject to extensive environmental regulation and legislation by local, state, and Federal authorities. These laws and regulations affect the way the Registrants conduct their operations
and  make  capital  expenditures,  including  how  they  handle  air  and  water  emissions,  hazardous  and  solid  waste,  and  activities  affecting  surface  waters,  groundwater,  and  aquatic  and  other  species.
Violations of these requirements could subject the Registrants to enforcement actions, capital expenditures to bring existing facilities into compliance, additional operating costs for remediation and clean-
up costs, civil penalties and exposure to third parties’ claims

25

Table of Contents

for  alleged  health  or  property  damages,  or  operating  restrictions  to  achieve  compliance.  In  addition,  the  Registrants  are  subject  to  liability  under  these  laws  for  the  remediation  costs  for  environmental
contamination  of  property  now  or  formerly  owned  by  the  Registrants  and  of  property  contaminated  by  hazardous  substances  they  generated  or  released.  Remediation  activities  associated  with  MGP
operations conducted by predecessor companies are one component of such costs. Also, the Registrants are currently involved in several proceedings relating to sites where hazardous substances have
been deposited and could be subject to additional proceedings in the future. See ITEM 1. BUSINESS — Environmental Matters and Regulation for additional information.

The Registrants could be negatively affected by federal and state RPS and/or energy conservation legislation, along with energy conservation by customers (All Registrants).

Changes  to  current  state  legislation  or  the  development  of  Federal  legislation  that  requires  the  use  of  low-emission,  renewable,  and/or  alternate  fuel  sources  could  significantly  impact  the  Utility
Registrants, especially if timely cost recovery is not allowed.

Federal and state legislation mandating the implementation of energy conservation programs that require the implementation of new technologies, such as smart meters and smart grid, could increase
capital expenditures and could significantly impact the Utility Registrants' consolidated financial statements if timely cost recovery is not allowed. These energy conservation programs, regulated energy
consumption reduction targets, and new energy consumption technologies could cause declines in customer energy consumption and lead to a decline in the Registrants' earnings, if timely recovery is not
allowed. See ITEM 1. BUSINESS — Environmental Matters and Regulation — Renewable and Clean Energy Standards and "The Registrants are potentially affected by emerging technologies that could
over time affect or transform the energy industry" above for additional information.

The Registrants could be negatively affected by challenges to tax positions taken, tax law changes, and the inherent difficulty in quantifying potential tax effects of business
decisions. (All Registrants).

The Registrants are required to make judgments to estimate their obligations to taxing authorities, which includes general tax positions taken and associated reserves established. Tax obligations include,
but are not limited to: income, real estate, sales and use, and employment-related taxes and ongoing appeal issues related to these tax matters. All tax estimates could be subject to challenge by the tax
authorities. Additionally, earnings may be impacted due to changes in federal or local/state tax laws, and the inherent difficulty of estimating potential tax effects of ongoing business decisions. See Note 1
— Significant Accounting Policies and Note 13 — Income Taxes of the Combined Notes to Consolidated Financial Statements for additional information.

Legal proceedings could result in a negative outcome, which the Registrants cannot predict (All Registrants).

The Registrants are involved in legal proceedings, claims, and litigation arising out of their business operations. The material ones are summarized in Note 18  — Commitments and Contingencies of the
Combined Notes to Consolidated Financial Statements. Adverse outcomes in these proceedings could require significant expenditures, result in lost revenue, or restrict or disrupt business activities.

The  Registrants  could  be  subject  to  adverse  publicity  and  reputational  risks,  which  make  them  vulnerable  to  negative  customer  perception  and  could  lead  to  increased
regulatory oversight or other consequences (All Registrants).

The Registrants could be the  subject  of  public  criticism. Adverse  publicity  could  render  public  service  commissions  and  other  regulatory  and  legislative  authorities  less  likely  to  view  energy  companies
generally,  or  the  Registrants  specifically,  in  a  favorable  light,  and  could  cause  the  Registrants  to  be  susceptible  to  less  favorable  legislative  and  regulatory  outcomes,  as  well  as  increased  regulatory
oversight and more stringent legislative or regulatory requirements.

The activities associated with the past Deferred Prosecution Agreement and the now resolved associated SEC investigation could have a material adverse effect on Exelon’s
and ComEd’s

26

Table of Contents

reputation and relationship with legislators, regulators, and customers that could affect their ability to achieve actions and approvals (Exelon and ComEd).

On  July  17,  2020,  ComEd  entered  into  a  Deferred  Prosecution Agreement  with  the  USAO  for  the  Northern  District  of  Illinois  to  resolve  the  USAO’s  investigation  into  Exelon’s  and  ComEd’s  lobbying
activities in the State of Illinois. Exelon was not made a party to the DPA and no charges were brought against Exelon. Under the DPA, the USAO filed a single charge alleging that ComEd improperly gave
and  offered  to  give  jobs,  vendor  subcontracts,  and  payments  associated  with  those  jobs  and  subcontracts  for  the  benefit  of  the  Speaker  of  the  Illinois  House  of  Representatives  and  the  Speaker’s
associates, with the intent to influence the Speaker’s action regarding legislation affecting ComEd’s interests. The DPA provided that the USAO would defer any prosecution of such charge and any other
criminal or civil case against ComEd in connection with the matters identified therein for a three-year period. That period expired, and the pending charge was dismissed, in July 2023. In October 2019, the
SEC notified Exelon and ComEd that it had opened an investigation into their lobbying activities in the state of Illinois. On September 28, 2023, Exelon and ComEd reached a settlement with the SEC to
fully resolve the matter.

The  DPA  and  the  settlement  with  the  SEC  could  have  a  material  adverse  impact  on  Exelon’s  and  ComEd’s  reputation  or  relationships  with  regulatory  and  legislative  authorities,  customers,  and  other
stakeholders. Those impacts could affect, or make more difficult, their efforts to achieve actions or approvals associated with operations. See Note 18 — Commitments and Contingencies of the Combined
Notes to Consolidated Financial Statements for more information regarding the DPA and SEC settlement.

Risks Related to Operational Factors

The Registrants are subject to risks associated with climate change (All Registrants).

The  Registrants  periodically  perform  analyses  to  better  understand  long-term  projections  of  climate  change  and  how  those  changes  in  the  physical  environments  where  they  operate  could  affect  their
facilities and operations. The Registrants primarily operate in the Midwest and Mid-Atlantic of the United States, areas that historically have been prone to various types of severe weather events, and the
Registrants  have  well-developed  response  and  recovery  programs  based  on  these  historical  events.  However,  the  Registrants’  physical  facilities  could  be  at  greater  risk  of  damage  as  changes  in  the
global  climate  affect  temperature  and  weather  patterns,  including  if  such  climate  changes  result  in  more  intense,  frequent  and  extreme  weather  events,  elevated  levels  of  precipitation,  sea  level  rise,
increased surface water temperatures, wildfires and/or other effects. Over time, the Registrants are making additional investments to protect their facilities from physical climate-related risks.

In  addition,  changes  to  the  climate  may  impact  levels  and  patterns  of  demand  for  energy  and  related  services,  which  could  affect  Registrants’  operations  and  business.  Over  time,  the  Registrants  are
making additional investments to adapt to changes in operational requirements to manage demand changes and customer expectations caused by climate change.

Climate Change risks include changes to energy systems due to new technologies, changing customer expectations and/or voluntary GHG goals, as well as local, state, or federal regulatory requirements
intended  to  reduce  GHG  emissions,  including  through  limitation  of  the  use  of  natural  gas.  The  Registrants  also  periodically  perform  analyses  of  potential  energy  system  transition  pathways  to  reduce
economy-wide GHG emissions to mitigate climate change. To the extent additional GHG reduction legislation and/or regulation becomes effective at the Federal and/or state levels, the Registrants could
incur costs to further limit the GHG emissions from their operations or otherwise comply with applicable requirements and such legislation and/or regulation could otherwise adversely affect the Registrants'
businesses. See ITEM 1. BUSINESS — Environmental Matters and Regulation — Climate Change and ITEM 1.A. "The Registrants are potentially affected by emerging technologies that could over time
affect or transform the energy industry" above for additional information.

The Utility Registrants' operating costs are affected by their ability to maintain the availability and reliability of their delivery and operational systems (All Registrants).

Failures of the equipment or facilities used in the Utility Registrants' delivery systems could interrupt electric transmission and/or electric or natural gas delivery, which could result in a loss of revenues and
an increase in maintenance and capital expenditures. Equipment or facilities failures can occur due to several factors, including natural causes such as weather or information systems failure. Specifically,
if the implementation of AMI, smart

27

Table of Contents

grid,  or  other  technologies  in  the  Utility  Registrants'  service  territory  fail  to  perform  as  intended  or  are  not  successfully  integrated  with  billing  and  other  information  systems,  or  if  any  of  the  financial,
accounting, or other data processing systems fail or have other significant shortcomings, the Utility Registrants' financial results could be negatively impacted. In addition, dependence upon automated
systems could further increase the risk that operational system flaws or internal and/or external tampering or manipulation of those systems will result in losses that are difficult to detect.

Regulated utilities, which are required to provide service to all customers within their respective service territories, have generally been afforded liability protections against claims by customers relating to
failure  of  service.  Under  Illinois  law,  however,  ComEd  could  be  required  to  pay  damages  to  its  customers  in  some  circumstances  involving  extended  outages  affecting  large  numbers  of  its  customers,
which could be material.

The Registrants are subject to physical security and cybersecurity risks (All Registrants).

Risks from cybersecurity and physical threats to energy infrastructures are increasing. Threat actors, including sophisticated nation-state actors, continue to seek to exploit potential vulnerabilities in the
electric and natural gas utility industry, grid infrastructure, and other energy infrastructures, and attacks and disruptions, both physical, cyber, and hybrid targeting physical and cyber assets, are becoming
increasingly sophisticated and dynamic. Several U.S. government agencies have warned of increased risks related to physical attacks, ransomware attacks and cybersecurity threats related to the energy
sector  and  its  supply  chains,  and  that  the  risks  may  escalate  during  periods  of  heightened  geopolitical  tensions. Continued  implementation  of  advanced  digital  technologies  increases  the  potentially
unfavorable impacts of such attacks. In addition, the rapid evolution and increased adoption of artificial intelligence technologies may intensify the Registrants' cybersecurity risks.

A security breach of the Registrants' physical assets or information systems or those of the Registrants' competitors, vendors, business partners and interconnected entities (including RTOs and ISOs)
could materially impact Registrants by, among other things, impairing the availability of electricity and gas distributed by Registrants and/or the reliability of transmission and distribution systems, damaging
grid infrastructure, interrupting critical business functions, impairing the availability of vendor services and materials that the Registrants rely on to maintain their operations, or by leading to the theft or
inappropriate release of certain types of information, including critical infrastructure information, system data and architecture, sensitive customer, vendor, or employee data, or other confidential data. The
Registrants'  reliance  on  vendors  to  provide  services  and  equipment,  and  its  shared  information  systems  with  Constellation  pursuant  to  the  Transition  Services  Agreement  between  Exelon  and
Constellation,  increases  the  risk  to  assets,  systems,  and  data. While  some  of  the  Registrants'  vendors  have  experienced  cybersecurity  incidents,  such  incidents  have  not,  to  Registrants'  knowledge,
resulted  in  material  impact  to  any  of  the  Registrants  to  date. The  risk  of  these  events  and  security  breaches  occurring  continues  to  intensify.  The  Registrants  have  been,  and  will  likely  continue  to  be,
subjected to physical and cyber-attacks. While to date none of the Registrants has directly experienced a material breach or material disruption to its network or information systems or operations, as such
attacks continue to increase in sophistication and frequency, the Registrants may be subject to a material breach or material disruption in the future.

If a significant physical or cybersecurity breach or disruption were to occur, the Registrants' reputation could be negatively affected, customer confidence in the Registrants could be diminished and the
Registrants  could  be  subject  to  legal  claims,  regulatory  exposure,  loss  of  revenues,  increased  costs  including  for  infrastructure  repairs,  or  operations  shutdown,  all  of  which  could  materially  affect  the
Registrants'  financial  condition  and  materially  damage  its  business  reputation.  Moreover,  the  amount  and  scope  of  insurance  maintained  against  losses  resulting  from  any  such  security  breaches  or
disruptions may not be sufficient to cover losses or otherwise adequately compensate for any disruptions to business that could result. The continued increase in Federal and state regulatory requirements
related  to  cybersecurity  and  evolving  threat  actor-capabilities  could  require  changes  to  current  measures  taken  by  the  Registrants  or  to  their  business  operations  and  could  adversely  affect  their
consolidated financial statements.

The Registrants’ employees, contractors, customers, and the general public could be exposed to a risk of injury due to the nature of the energy industry (All Registrants).

Employees and contractors throughout the organization work in, and customers and the general public could be exposed to, potentially dangerous environments near the Registrants’ operations. As a
result, employees,

28

Table of Contents

contractors, customers, and the general public are at some risk for serious injury, including loss of life. These risks include gas explosions, pole strikes, and electric contact cases.

Extreme  weather  events,  natural  disasters,  operational  accidents  such  as  wildfires  or  natural  gas  explosions,  war,  acts  and  threats  of  terrorism,  public  health  crises,
epidemics, pandemics, or other significant events could negatively impact the Registrants' results of operations, ability to raise capital and future growth (All Registrants).

The Utility Registrants' infrastructures and/or operations could be affected by extreme weather events, natural disasters, or operational accidents such as wildfires or natural gas explosions which could
result in increased costs, including supply chain costs and third-party property damage. An extreme weather event, natural disaster, or operational accident within the Utility Registrants’ service areas can
also directly affect their capital assets, causing disruption in service to customers due to downed wires and poles or damage to other operating equipment.

The impact that potential terrorist attacks could have on the industry and the Registrants is uncertain. The Registrants face a risk that their operations would be direct targets or indirect casualties of an act
of terror. Any retaliatory military strikes or sustained military campaign could affect Registrants' operations in unpredictable ways, such as changes in insurance markets and disruptions of supplies and
markets. Furthermore, such events could compromise the physical or cybersecurity of the Registrants' facilities, which could adversely affect the Registrants' ability to manage their businesses effectively.
Instability in the financial markets as a result of terrorism, war, natural disasters, public health crises, epidemics, pandemics, credit crises, recession, or other significant events also could result in a decline
in energy consumption or interruption of fuel or the supply chain. In addition, the implementation of security guidelines and measures has resulted in and is expected to continue to result in increased costs.

The Registrants could be significantly affected by public health crises, epidemics, or pandemics. The Registrants have plans in place to respond to such events. However, depending on the severity and
the  resulting  impacts  to  workforce  and  other  resource  availability,  a  public  health  crisis,  epidemic,  or  pandemic  could  adversely  affect  our  vendors,  or  customers  and  customer  demand  as  well  as  the
Registrants’ ability to operate their transmission and distribution assets.

In  addition,  on  behalf  of  the  Registrants  Exelon  maintains  a  level  of  insurance  coverage  consistent  with  industry  practices  against  property,  casualty,  and  cybersecurity  losses  subject  to  unforeseen
occurrences  or  catastrophic  events  that  could  damage  or  destroy  assets  or  interrupt  operations.  However,  there  can  be  no  assurance  that  the  amount  of  insurance  will  be  adequate  to  address  such
property and casualty losses.

The Registrants’ businesses are capital intensive, and their assets could require significant expenditures to maintain, are subject to operational failure and could be impacted
by lack of availability of labor, materials or parts, which could result in potential liability (All Registrants).

The Utility Registrants’ businesses are capital intensive and require significant investments in transmission and distribution infrastructure projects. Equipment, even if maintained in accordance with good
utility  practices,  is  subject  to  operational  failure,  including  events  that  are  beyond  the  Utility  Registrants’  control,  and  could  require  significant  expenditures  to  operate  efficiently.  Disruptions  or  cost
increases in the supply chain, including shortages in labor, materials or parts, could materially impact the timing and execution of capital projects, as well as other aspects of the Registrants' businesses.
The Registrants' consolidated financial statements could be negatively affected if they were unable to effectively manage their capital projects or raise the necessary capital, or if they are deemed liable for
operational  failure.  See  ITEM  7.  MANAGEMENT'S  DISCUSSION AND ANALYSIS  OF  FINANCIAL  CONDITION AND  RESULTS  OF  OPERATIONS  —  Liquidity  and  Capital  Resources  for  additional
information regarding the Registrants’ potential future capital expenditures.

The Utility Registrants' respective ability to deliver electricity, their operating costs, and their capital expenditures could be negatively impacted by transmission congestion
and failures of neighboring transmission systems (All Registrants).

Demand for electricity within the Utility Registrants' service areas could stress available transmission capacity requiring alternative routing or curtailment of electricity usage. Also, insufficient availability of
electric supply to meet customer demand could jeopardize the Utility Registrants' ability to comply with reliability standards and

29

Table of Contents

strain  customer  and  regulatory  agency  relationships. As  is  the  case  for  electric  utilities  generally,  potential  concerns  over  transmission  capacity  or  generation  facility  retirements  could  result  in  PJM  or
FERC requiring the Utility Registrants to upgrade or expand their respective transmission systems through additional capital expenditures.

PJM’s systems and operations are designed to ensure the reliable operation of the transmission grid and prevent the operations of one utility from having an adverse impact on the operations of the other
utilities. However, service interruptions at other utilities may cause interruptions in the Utility Registrants’ service areas.

The Registrants' performance could be negatively affected if they fail to attract and retain an appropriately qualified workforce (All Registrants).

Certain events, such as the separation transaction, an employee strike, loss of employees, loss of contract resources due to a major event, and an aging workforce without appropriate replacements, could
lead to operating challenges and increased costs for the Registrants. Such challenges include lack of resources, loss of knowledge and a lengthy time period associated with skill development. As a result
of  such  events,  costs,  including  costs  for  contractors  to  replace  employees,  productivity  costs,  and  safety  costs,  could  rise.  The  Registrants  are  particularly  affected  due  to  the  specialized  knowledge
required of the technical and support employees needed to conduct Registrants' transmission and distribution operations as well as areas where new technologies are pertinent.

The Registrants’ performance could be negatively affected by poor performance of third-party contractors that perform periodic or ongoing work (All Registrants).

The Registrants rely on third-party contractors to perform operations, maintenance, and construction work. Performance standards typically are included in all contractual obligations, but poor performance
may impact capital execution plans or operations, or have adverse financial or reputational consequences.

The Registrants could make acquisitions or investments in new business initiatives and new markets, which may not be successful or achieve the intended financial results
(All Registrants).

The Utility Registrants face risks associated with regulator-mandated or other new business initiatives, such as smart grids and broader beneficial electrification. Such risks include, but are not limited to,
cost recovery, regulatory concerns, cybersecurity, and obsolescence of technology. Such initiatives may not be successful, and failures could result in adverse financial or reputational consequences.

Risks Related to the Separation (Exelon)

In connection with the separation into two public companies, Exelon and Constellation have agreed to indemnify each other for certain liabilities. If Exelon is required to pay
under these indemnities to Constellation, Exelon's financial results could be negatively impacted. The Constellation indemnities may not be sufficient to hold Exelon harmless
from the full amount of liabilities for which Constellation has been allocated responsibility, and Constellation may not be able to satisfy its indemnification obligations in the
future.

Pursuant to the separation agreement and certain other agreements between Exelon and Constellation, each party agreed to indemnify the other for certain liabilities, generally for uncapped amounts.
Liabilities subject to Exelon’s indemnity obligations to Constellation generally are not subject to caps, may be significant and could negatively impact Exelon’s business. Any amounts Exelon is required to
pay  pursuant  to  these  indemnity  obligations  could  require  Exelon  to  divert  cash  that  would  otherwise  have  been  used  in  furtherance  of  its  operating  business.  Further,  third  parties  could  seek  to  hold
Exelon responsible for any of the liabilities that Constellation has agreed to retain and for which Constellation is obligated to indemnify Exelon. The indemnities from Constellation for Exelon's benefit may
not be sufficient to protect Exelon against the full amount of such liabilities, and Constellation may not be able to fully satisfy its indemnification obligations. Even if Exelon ultimately succeeds in recovering
from Constellation any amounts for which Exelon is held liable, Exelon may be temporarily required to bear these losses. Each of these risks could negatively affect Exelon's business, results of operations
and financial condition.

ITEM 1C.

CYBERSECURITY

Risk management and strategy

Cybersecurity risk for all Registrants is managed at the enterprise-level. Management of material risks from cybersecurity threats is integrated into the Registrants' overall risk management processes and
is monitored as an enterprise risk. Exelon's Chief Information Security Officer (CISO) and cybersecurity management team regularly hold meetings with senior management of each Registrant, facilitated
by Exelon’s enterprise risk management team, to discuss issues pertaining to cybersecurity risk management, including changes in the nature and origin of threats, threat actor and risk mitigation activities,
and regulatory developments. Exelon Legal and compliance professionals engage with the CISO and cybersecurity management team to address tactical and strategic cybersecurity risks. Exelon monitors
cybersecurity  risks  through  key  risk  indicators  to  identify  potential  changes  in  risk  exposure  and  provide  the  Board  of  Directors  with  information  about  the  monitoring  of  key  risks  in  connection  with  its
oversight of the Registrants' enterprise risk management system.

The CISO, through Exelon’s Cyber Information and Security Services (CISS), reviews external and internal sources to obtain cyber threat intelligence to develop strategic and tactical threat assessments
that inform the enterprise-wide cyber risk mitigation programs and actions. Exelon uses a wide range of tools, including endpoint, anomaly and network detection, logging and monitoring of security events,
network  segmentation,  firewalls,  hardening  and  securing  devices,  cyber  vulnerability  detection  and  patch  management,  cyber  threat  hunting,  malware  forensic  analysis,  industry-specific  reports,  and
tabletop exercises to inform the cybersecurity management team. Exelon protects assets critical to grid reliability and national security through the implementation of the North American Electric Reliability
Corporation’s Critical Infrastructure Protection requirements, and gas pipeline security under the U.S. Department of Homeland Security’s Transportation Safety Administration’s Security Directives. Exelon
maintains security relationships with law enforcement and U.S. intelligence agencies, coordinates with the Electricity Information Sharing and Analysis Center (E-ISAC) and participates in the Department
of Energy’s Cybersecurity Risk Information Sharing Program (CRISP) to strengthen the security of the energy grid, develop and deploy new technologies, share information, design and participate in drills
and  exercises  such  as  the  bi-annual  Grid  Security  Exercises  and  facilitate  cross-sector  coordination.  Exelon  applies  stringent  employee  and  contractor  screening,  and  advances  security  awareness
through training and monitoring programs that address both cyber and physical threats. Exelon employees are subject to annual mandatory training addressing security awareness, including cybersecurity
and phishing. Exelon maintains cyber insurance coverage at limits consistent with the utility industry and reviews policy coverage and limits on an annual basis.

In  assessing  the  effectiveness  of  its  cybersecurity  risk  management  program,  the  CISO  makes  use  of  external  perspectives  from  regulatory  compliance  audits  and  inspections,  external  audits  of  the
Registrants' financial systems, and third-party incident response and detection analytics. Cybersecurity risks associated with the Registrants’ use of certain third-party service providers are evaluated and
managed  through  CISS'  Third  Party  Security  team  that  leverages  security  risk  assessments,  contractual  terms  and  conditions,  and  security  awareness  training  for  such  providers. Additionally,  those
providers  are  required  to  report  cybersecurity  incidents,  including  the  unauthorized  use  or  disclosure  of  Registrants’  confidential  information  to  Exelon’s  security  operations  center. Third  Party  Security
investigates certain third-party cybersecurity events as part of Exelon’s incident response program.

Governance

The  Exelon  Board  of  Directors  is  responsible  for  oversight  of  risks  from  cybersecurity  threats. As  part  of  its  responsibility  and  as  documented  in  the  2022  Cybersecurity  Oversight  Policy,  the  Board  of
Directors oversees Exelon's cybersecurity program and Exelon’s enterprise-wide risk related to cybersecurity, including management’s identification, assessment, and mitigation of cybersecurity risks. At
each regular quarterly meeting, the Board of Directors engages with the CISO and a cross-functional management team regarding the risks from cybersecurity threats. The CISO and professionals from the
legal and compliance departments brief

31

Table of Contents

the Board of Directors on relevant topics, including information security and operational security, legislative and regulatory developments, and notable external cyber events relevant to Exelon and the
industry more broadly. Management engages with the Board of Directors on risks from cybersecurity threats as appropriate outside of the quarterly meetings.

The CISO manages Exelon's enterprise-wide cybersecurity programs and reports to Exelon’s Chief Information Officer. The CISO has been responsible for assessing and managing material risks from
cybersecurity threats at Exelon since 2018 and was named to the current role in 2022. The CISO has 25 years of information technology and cybersecurity experience in the critical infrastructure sector, of
which 23 years have been in the utility industry.  The CISO leads CISS, which manages centralized information technology and operational technology security programs for the Registrants. The programs
are aligned to the National Institute of Standards and Technology Cyber Security Framework (NIST CSF) and integrate cyber asset identification; threat assessment; risk assessment; risk management;
and risk monitoring. CISS operates a security operations center for monitoring, identifying, and mitigating potential cybersecurity events or incidents.

Exelon maintains a single, centralized cybersecurity incident response program and plan that aligns with NIST CSF by integrating the identify, determine/classify, escalate and respond functions (which
track the lifecycle of an event or incident). Security threats and incidents are identified and assessed to determine potential impact and escalated to senior cybersecurity management and the CISO. The
CISO directs the security incident response team to contain, eradicate, and recover from an active threat. Exelon leverages the expertise of dedicated incident response vendors that can provide timely
and specialized support to respond and recover from an event. The CISO and a cross-functional team convene as needed to evaluate cybersecurity events, including third-party events. The legal and
compliance  departments  provide  incident  response  support  to  the  CISO,  manage  cybersecurity-related  legal  and  compliance  issues,  and  direct  materiality  evaluations  using  both  qualitative  and
quantitative factors for each Registrant.

Although the Registrants have not experienced any material cybersecurity events to date, cybersecurity threats could materially affect each Registrant’s business strategy, results of operations, or financial
condition, as further discussed in the risk factor entitled “The Registrants are subject to physical and cybersecurity risks" in ITEM 1A. of this report.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(Dollars in millions except per share data, unless otherwise noted)

Exelon

Executive Overview

Exelon is a utility services holding company engaged in the energy transmission and distribution businesses through its six reportable segments: ComEd, PECO, BGE, Pepco, DPL, and ACE. See Note 1
— Significant Accounting Policies and Note 5 — Segment Information of the Combined Notes to Consolidated Financial Statements for additional information regarding Exelon's principal subsidiaries and
reportable segments.

Exelon’s  consolidated  financial  information  includes  the  results  of  its  seven  separate  operating  subsidiary  registrants,  ComEd,  PECO,  BGE,  PHI,  Pepco,  DPL,  and ACE,  which,  along  with  Exelon,  are
collectively referred to as the Registrants. The following combined Management’s Discussion and Analysis of Financial Condition and Results of Operations is separately filed by Exelon, ComEd, PECO,
BGE, PHI, Pepco, DPL, and ACE. However, none of the Registrants makes any representation as to information related solely to any of the other Registrants. For discussion of the Utility Registrants' year
ended  December  31,  2022  compared  to  the  year  ended  December  31,  2021,  refer  to  ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF
OPERATIONS in the 2022 Form 10-K, which was filed with the SEC on February 14, 2023.

COVID-19. There were no material impacts to the Registrants from unfavorable economic conditions due to COVID-19 for the years ended December 31, 2023 and 2022, other than the 2022 impairment
discussed below.

The Registrants assessed long-lived assets, goodwill, and investments for recoverability. Exelon and BGE recorded a pre-tax impairment charge of $48 million in 2022 as a result of COVID-19 impacts on
office use. See Note 11 — Asset Impairments for additional information related to this impairment assessment.

Financial Results of Operations

GAAP Results of Operations. The following table sets forth Exelon's GAAP consolidated Net income attributable to common shareholders from continuing operations by Registrant for the year ended
December 31, 2023 compared to the same period in 2022. For additional information regarding the financial results for the years ended December 31, 2023 and 2022, see the discussions of Results of
Operations by Registrant.

The  separation  of  Constellation,  including  Generation  and  its  subsidiaries,  met  the  criteria  for  discontinued  operations  and  as  such,  Generation's  results  of  operations  are  presented  as  discontinued
operations and have been excluded from Exelon's continuing operations for the year ended December 31, 2022 presented in the table

Table of Contents

above. See Note 1 — Significant Accounting Policies and Note 2 — Discontinued Operations for additional information.

Accounting rules require certain BSC costs previously allocated to Generation to be presented as part of Exelon’s continuing operations as these costs do not qualify as expenses of the  discontinued
operations. Such costs are included in Other in the table above and were $28 million on a pre-tax basis, for the year ended December 31, 2022. There were no such costs included in Exelon's continuing
operations for the year ended December 31, 2023

Year  Ended  December  31,  2023  Compared  to  Year  Ended  December  31,  2022.  Net  income  attributable  to  common  shareholders  from  continuing  operations increased  by  $274  million  and
Diluted earnings per average common share from continuing operations increased to $2.34 in 2023 from $2.08 in 2022 primarily due to:

•

•

•

•

•

Higher electric distribution and transmission earnings from higher allowed ROE due to an increase in treasury rates and higher rate base at ComEd;

Favorable impacts of rate increases at PECO, BGE, and PHI;

Favorable impacts of the multi-year plans including the recognition of the reconciliation in 2023 at BGE;

Higher carrying costs related to the CMC regulatory assets at ComEd; and

Lower BSC costs presented in Exelon’s continuing operations, which were previously allocated to Generation but do not qualify as expenses of the discontinued operation per the accounting
rules.

The increases were partially offset by:

•

•

•

•

•

•

Higher interest expense at PECO, BGE, PHI, and Exelon Corporate;

Unfavorable weather at PECO and PHI;

Higher depreciation expense at PECO, BGE, and PHI;

Higher contracting costs at PHI;

Higher storm costs at PECO and BGE; and

Higher realized losses from hedging activity at Exelon Corporate.

Adjusted (non-GAAP) operating earnings. In addition to Net income, Exelon evaluates its operating performance using the measure of Adjusted (non-GAAP) operating earnings because management
believes it represents earnings directly related to the ongoing operations of the business. Adjusted (non-GAAP) operating earnings exclude certain costs, expenses, gains and losses, and other specified
items. This information is intended to enhance an investor’s overall understanding of year-over-year operating results and provide an indication of Exelon’s baseline operating performance excluding items
not considered by management to be directly related to the ongoing operations of the business. In addition, this information is among the primary indicators management uses as a basis for evaluating
performance,  allocating  resources,  setting  incentive  compensation  targets,  and  planning  and  forecasting  of  future  periods. Adjusted  (non-GAAP)  operating  earnings  is  not  a  presentation  defined  under
GAAP and may not be comparable to other companies’ presentations or deemed more useful than the GAAP information provided elsewhere in this report.

__________
Note:
Amounts may not sum due to rounding.
Unless otherwise noted, the income tax impact of each reconciling item between GAAP Net income and Adjusted (non-GAAP) operating earnings is based on the marginal statutory federal and state income tax rates for
each Registrant, taking into account whether the income or expense item is taxable or deductible, respectively, in whole or in part. The marginal statutory income tax rates for 2023 and 2022 ranged from 24.0% to 29.0%.

(a) Reflects costs related to a multi-year ERP system implementation, which are recorded in Operating and maintenance expense.
(b) Reflects costs related to the impairment of an office building at BGE, which are recorded in Operating and maintenance expense.
(c) Represents  costs  related  to  the  separation  primarily  comprised  of  system-related  costs,  third-party  costs  paid  to  advisors,  consultants,  lawyers,  and  other  experts  assisting  in  the  separation,  and  employee-related

(d)

severance costs, which are recorded in Operating and maintenance expense and Other, net.
In 2022, for PECO, primarily reflects an adjustment to exclude one-time non-cash impacts associated with the remeasurement of deferred income taxes as a result of the reduction in Pennsylvania corporate income tax
rate. For Corporate, in connection with the separation, Exelon recorded an income tax expense primarily due to the long-term marginal state income tax rate change, the recognition of valuation allowances against the
net  deferred  tax  assets  positions  for  certain  standalone  state  filing  jurisdictions,  and  nondeductible  transaction  costs  partially  offset  by  a  one-time  impact  associated  with  a  state  tax  benefit.  In  2023,  reflects  the
adjustment to state deferred income taxes due to changes in forecasted apportionment.

Significant 2023 Transactions and Developments

Separation

On February 21, 2021, Exelon’s Board of Directors approved a plan to separate the Utility Registrants and Generation, creating two publicly traded companies (“the separation”). Exelon completed the
separation on February 1, 2022. Constellation was newly formed and incorporated in Pennsylvania on June 15, 2021 for the purpose of separation and holds Generation. The separation represented a
strategic shift that would have a major effect on Exelon’s operations and financial results. Accordingly, the separation meets the criteria for discontinued operations. See Note 2 — Discontinued Operations
of the Combined Notes to Consolidated Financial Statements for additional information on the separation and discontinued operations.

Table of Contents

In connection with the separation, Exelon incurred separation costs impacting continuing operations of $29 million and $34 million on a pre-tax basis for the year ended December 31, 2023 and 2022,
respectively,  which  are  recorded  in  Operating  and  maintenance  expense.  These  costs  are  excluded  from Adjusted  (non-GAAP)  Operating  Earnings.  The  separation  costs  are  primarily  comprised  of
system-related costs, third-party costs paid to advisors, consultants, lawyers, and other experts assisting in the separation, and employee-related severance costs.

At-the-Market Program

In  November  and  December  2023,  Exelon  issued  approximately  3.6  million  shares  of  Common  stock  at  an  average  gross  price  of  $39.58  per  share. The  net  proceeds  from  these  issuances  were
$140 million, which were used for general corporate purposes. See Note 19 — Shareholders' Equity of the Combined Notes to Consolidated Financial Statements for additional information.

Distribution Base Rate Case Proceedings

The Utility Registrants file base rate cases with their regulatory commissions seeking increases or decreases to their electric transmission and distribution, and gas distribution rates to recover their costs
and earn a fair return on their investments. The outcomes of these regulatory proceedings impact the Utility Registrants’ current and future financial statements.

The  following  tables  show  the  Utility  Registrants’  completed  and  pending  distribution  base  rate  case  proceedings  in  2023.  See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated

The  Utility  Registrants  are  subject  to  periodic  audits  and  investigations  by  FERC.  FERC’s  Division  of Audits  and Accounting  initiated  a  nonpublic  audit  of  ComEd  in April  2021  evaluating  ComEd’s
compliance with (1) approved terms, rates and conditions of its federally regulated service; (2) accounting requirements of the Uniform System of Accounts; (3) reporting requirements of the FERC Form 1;
and (4) the requirements for record retention. The audit period extends back to January 1, 2017. During the first quarter of 2023, ComEd was provided with information from FERC about several potential
findings, including ComEd's methodology regarding the allocation of certain overhead costs to capital under FERC regulations. Based on the preliminary findings and discussions with FERC staff, ComEd
determined that a loss was probable and recorded a regulatory liability to reflect its best estimate of that loss in the first quarter of 2023.

On July 27, 2023, FERC issued a final audit report which included, among other things, findings and recommendations related to ComEd's methodology regarding the allocation of certain overhead costs
to capitalized construction costs under FERC regulations, including a suggestion that refunds may be due to customers for amounts collected in previous years. On August 28, 2023, ComEd filed a formal
notice of the issues it will contest. On December 14, 2023, FERC appointed a settlement judge for the contested overhead allocation findings. The final outcome and resolution of any contested audit issues
as well as a reasonable estimate of potential future losses cannot be accurately estimated at this stage; however, the final resolution of these matters could result in recognition of future losses, above the
amounts currently accrued, that could be material to the Exelon and ComEd financial statements.

ACE Employee Strike

ACE’s collective bargaining agreement with the International Brotherhood of Electrical Workers (IBEW) Local 210, expired on November 2, 2023. On November 5, 2023, IBEW Local 210 initiated a strike in
ACE’s service territory. While the work stoppage did not result in a disruption in service to customers, Exelon, PHI, and ACE incurred unfavorable impacts to Net income of approximately $31 million,
$31 million, and $32 million for the year ended December 31, 2023. On December 5, 2023, IBEW Local 210 ratified a new collective bargaining agreement with ACE and ceased the work stoppage.

proceedings.

Legislative and Regulatory Developments

Infrastructure Investment and Jobs Act

On November 15, 2021, President Biden signed the $1.2 trillion IIJA into law. IIJA provides for approximately $550 billion in new federal spending. Categories of funding include funding for a variety of
infrastructure  needs,  including  but  not  limited  to:  (1)  power  and  grid  reliability  and  resilience,  (2)  resilience  for  cybersecurity  to  address  critical  infrastructure  needs,  and  (3)  electric  vehicle  charging
infrastructure for alternative fuel corridors. Federal agencies are developing guidelines to implement spending programs under IIJA. The time needed to develop these guidelines will vary with some limited
program  applications  opened  as  early  as  the  first  quarter  of  2022.  The  Registrants  continue  to  evaluate  programs  under  the  legislation  and  consider  possible  opportunities  to  apply  for  funding,  either
directly or in potential collaborations with state and/or local agencies and key stakeholders. The Registrants cannot predict the ultimate timing and success of securing funding from programs under IIJA.

In  September  2022,  ComEd  and  BGE  applied  for  the  MMG,  which  establishes  and  funds  construction,  improvement,  or  acquisition  of  middle  mile  broadband  infrastructure  which  creates  high-speed
internet  services. The  MMG  addresses  inequitable  broadband  access  by  expansion  and  extension  of  the  middle  mile  infrastructure  in  underserved  communities.  In  June  2023,  the  National
Telecommunications  and  Information Administration  (NTIA)  announced  it  selected  two  of  the  applications  submitted  by  BGE  and  ComEd;  awarding  ComEd  and  BGE  $14.5  million  and  $15.4  million
respectively. The applications selected by  NTIA  for  BGE  and  ComEd  proposed  projects  designed  to  enhance  electric  grid  reliability  and  resiliency  while  leading  and  advancing  shared  local,  state,  and
national goals to increase broadband connectivity, redundancy, affordability, and equity.

In March 2023, Exelon, ComEd, and PHI submitted three applications related to the Smart Grid Grants program under section 40107 of IIJA. These applications are focused on replacing existing Advanced
Distribution Management Systems (ADMS) in support of distributed energy resources (DERs) and grid-edged technologies, strengthening interoperability and data architecture of systems in support of two-
way  power  flows  and  accelerating  advanced  metering  deployment  in  disadvantaged  communities.  In  October  2023,  ComEd’s  project,  Deployment  of  a  Community-Oriented  Interoperable  Control
Framework for Aggregating and Integrating Distributed Energy Resources and Other Grid-Edge Devices, was recommended by the Grid Deployment Office (GDO) for negotiation of a final award up to $50
million. This project will enable ComEd and its local partners to deploy the next generation of grid technologies that support the growth of solar and electric vehicles (EVs), while piloting new local workforce
training initiatives to support job creation connected to the clean energy transition. The GDO has indicated the award negotiation process can take approximately 120 days.

In April  2023,  ComEd,  PECO,  BGE,  and  PHI  submitted  seven  applications  related  to  the  Grid  Resilience  Grants  program  under  section  40101(c)  of  IIJA.  These  applications  are  broadly  focused  on
improving  grid  resilience  with  an  emphasis  on  disadvantaged  communities,  relief  of  capacity  constraints  and  modernizing  infrastructure,  deployment  of  DER  and  microgrid  technologies  and  providing
improved resilience through storm hardening projects. In October 2023, PECO’s project, Creating a Resilient, Equitable, and Accessible Transformation in Energy for Greater Philadelphia (CREATE), was
recommended by the GDO for negotiation of a final award up to $100 million. This project will support critical electric infrastructure investments to help reduce the impact of extreme weather and historic
flooding on the Registrants' electric distribution system. The GDO has indicated the award negotiation process can take approximately 120 days.

The Registrants are supporting three different Regional Clean Hydrogen Hub opportunities, covering all five states that Exelon operates in plus Washington D.C. under a program that will create networks
of hydrogen producers, consumers, and local connective infrastructure to accelerate the use of hydrogen as a clean energy carrier that can deliver or store energy. Applications for the three opportunities
under this program were submitted in April 2023. In October 2023 the DOE announced it selected two of the projects for further negotiation: (1) the Mid-Atlantic Clean Hydrogen Hub (MACH2), which is
being supported by PECO and PHI, and (2) the Midwest Alliance for Clean Hydrogen (MachH2), which is being supported by ComEd.

In November 2023, the GDO  announced  up  to  $3.9  billion  available  through  the  second-round  funding  opportunity  of  the  Grid  Resilience  and  Innovation  Partnerships  (GRIP)  Program  for  Fiscal  Years
2024 and 2025. This funding opportunity focuses on projects that will improve electric transmission by increasing funding and

46

Table of Contents

advancing interconnection processes for faster build out of energy projects, create comprehensive solutions that link grid communications systems and operations to increase resilience and reduce power
outages and threats, and deploy advanced technologies such as distributed energy resources and battery systems to provide essential grid services to ensure American communities across the country
have access to affordable, reliable, clean electricity. Exelon, ComEd, BGE, PHI, Pepco, DPL, and ACE submitted seven concept papers in response to the second round of the GRIP program. The concept
papers are focused on improving the resilience of the electric grid and deployment of technologies to enhance grid flexibility and deliver benefits to customers and communities across the Exelon footprint.
The  GDO  is  expected  to  issue  notifications  of  encouragement/discouragement  for  full  applications  in  the  first  quarter  of  2024.  Exelon  cannot  predict  if  their  concept  papers  will  receive  a  notification  of
encouragement to submit a full application.

PJM Regional Transmission Expansion

On April 6, 2023, PJM received a deactivation notice for Brandon Shores, a 1,282 MW coal generation plant located in BGE service territory. The deactivation was requested for June 1, 2025 and will result
in numerous reliability issues across the region. In June 2023, PJM assigned a portion of transmission system upgrades to mitigate these reliability impacts to PECO, BGE, and Pepco. In July 2023, PJM
Board  of  Managers  approved  assigning  Exelon  transmission  system  upgrades  to  mitigate  these  reliability  impacts  to  PECO,  BGE,  and  Pepco. The initial projected capital expenditures associated with
these upgrades are approximately $80 million, $650 million, and $80 million for PECO, BGE, and Pepco, respectively. These amounts include a scope reduction estimated by PJM for PECO of $60 million
associated with a transmission proposal window, as disclosed at a Transmission Expansion Advisory Committee meeting on October 31, 2023. The upgrades are expected to be completed by the end of
2028.

Separately,  PJM  held  a  competitive  transmission  proposal  window  from  February  24,  2023  through  May  31,  2023  to  address  reliability  issues  driven  by  significant  load  increases  in  northern  Virginia.
PECO, BGE, and Pepco submitted four solution proposals. At a meeting of the Transmission Expansion Advisory Committee on October 31, 2023, PJM recommended that PECO, BGE, Pepco, and DPL
be awarded a portion of the work for the proposed solution. Initial estimated costs for these upgrades are approximately $70 million, $700 million, $80 million, and $5 million for PECO, BGE, Pepco, and
DPL, respectively. The PJM Board of Managers approved the solution in December 2023 and the upgrades are expected to be completed by the end of 2030.

Critical Accounting Policies and Estimates

The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  that  management  apply  accounting  policies  and  make  estimates  and  assumptions  that  affect  results  of  operations  and  the
amounts  of  assets  and  liabilities  reported  in  the  financial  statements.  Management  believes  that  the  accounting  policies  described  below  require  significant  judgment  in  their  application  or  incorporate
estimates and assumptions that are inherently uncertain and that may change in subsequent periods. Additional information on the application of these accounting policies can be found in the Combined
Notes to Consolidated Financial Statements.

Goodwill (Exelon, ComEd, and PHI)

As  of  December  31,  2023,  Exelon’s  $6.6  billion  carrying  amount  of  goodwill  consists  of  $2.6  billion  at  ComEd  and  $4  billion  at  PHI.  These  entities  are  required  to  perform  an  assessment  for  possible
impairment of their goodwill at least annually or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting units below their carrying
amount. A reporting unit is an operating segment or one level below an operating segment (known as a component) and is the level at which goodwill is assessed for impairment. ComEd has a single
operating  segment  and  reporting  unit.  PHI’s  operating  segments  and  reporting  units  are  Pepco,  DPL,  and ACE.  See  Note  5  —  Segment  Information  of  the  Combined  Notes  to  Consolidated  Financial
Statements for additional information. Exelon's and ComEd’s goodwill has been assigned entirely to the ComEd reporting unit. Exelon's and PHI’s goodwill has been assigned to the Pepco, DPL, and ACE
reporting  units  in  the  amounts  of  $2.1  billion,  $1.4  billion,  and  $0.5  billion,  respectively.  See  Note  12  —  Intangible Assets  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional
information.

Entities assessing goodwill for impairment have the option of first performing a qualitative assessment to determine whether a quantitative assessment is necessary. As part of the qualitative assessments,
Exelon,  ComEd,  and  PHI  evaluate,  among  other  things,  management's  best  estimate  of  projected  operating  and  capital  cash  flows  for  their  businesses,  outcomes  of  recent  regulatory  proceedings,
changes in certain market

47

Table of Contents

conditions, including the discount rate and regulated utility peer EBITDA multiples, and the passing margin from their last quantitative assessments performed.

Application of the goodwill impairment assessment requires management judgment, including the identification of reporting units and determining the fair value of the reporting unit, which management
estimates using a weighted combination of a discounted cash flow analysis and a market multiples analysis. Significant assumptions used in these fair value analyses include discount and growth rates,
utility sector market performance and transactions, and projected operating and capital cash flows for ComEd’s, Pepco's, DPL's, and ACE's businesses and the fair value of debt.

While  the  2023  annual  assessments  indicated  no  impairments,  certain  assumptions  used  in  the  assessment  are  highly  sensitive  to  changes.  Adverse  regulatory  actions  or  changes  in  significant
assumptions could potentially result in future impairments of Exelon’s, ComEd's, or PHI’s goodwill, which could be material.

See Note 1 — Significant Accounting Policies and Note 12 — Intangible Assets of the Combined Notes to Consolidated Financial Statements for additional information.

Unamortized Energy Contract Liabilities (Exelon and PHI)

Unamortized energy contract liabilities represent the remaining unamortized balances of non-derivative electricity contracts that Exelon acquired as part of the PHI merger. The initial amount recorded
represents the difference between the fair value of the contracts at the time of acquisition and the contract value based on the terms of each contract. Offsetting regulatory assets were also recorded for
those energy contract costs that are probable of recovery through customer rates. The unamortized energy contract liabilities and the corresponding regulatory assets, respectively, are amortized over the
life of the contract in relation to the expected realization of the underlying cash flows. Amortization of the unamortized energy contract liabilities are recorded through Purchased power and fuel expense.
See Note 3 — Regulatory Matters and Note 12 — Intangible Assets of the Combined Notes to Consolidated Financial Statements for additional information.

Depreciable Lives of Property, Plant, and Equipment (All Registrants)

The Registrants have significant investments in electric and natural gas transmission and distribution assets. These assets are generally depreciated on a straight-line basis, using the group, or composite
methods of depreciation. The group approach is typically for groups of similar assets that have approximately the same useful lives and the composite approach is used for heterogeneous assets that have
different lives. Under both methods, a reporting entity depreciates the assets over the average life of the assets in the group. The estimation of asset useful lives requires management judgment, supported
by formal depreciation studies of historical asset retirement experience. Depreciation studies are conducted periodically and as required by a rate regulator or regulatory action, or changes in retirement
patterns indicate an update is necessary.

Depreciation studies generally serve as the basis for amounts allowed in customer rates for recovery of depreciation costs. Generally, the Registrants adjust their depreciation rates for financial reporting
purposes  concurrent  with  adjustments  to  depreciation  rates  reflected  in  customer  rates,  unless  the  depreciation  rates  reflected  in  customer  rates  do  not  align  with  management’s  judgment  as  to  an
appropriate estimated useful life or have not been updated on a timely basis. Depreciation expense and customer rates for ComEd, BGE, Pepco, DPL, and ACE include an estimate of the future costs of
dismantling  and  removing  plant  from  service  upon  retirement.  See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  the  Consolidated  Financial  Statements  for  information  regarding  regulatory
liabilities and assets recorded by ComEd, BGE, Pepco, DPL, and ACE related to removal costs.

PECO’s  removal  costs  are  capitalized  to  accumulated  depreciation  when  incurred  and  recorded  to  depreciation  expense  over  the  life  of  the  new  asset  constructed  consistent  with  PECO’s  regulatory
recovery method. Estimates for such removal costs are also evaluated in the periodic depreciation studies.

Changes in estimated useful lives of electric and natural gas transmission and distribution assets could have a significant impact on the Registrants’ future results of operations. See Note 1 — Significant
Accounting Policies of the Combined Notes to Consolidated Financial Statements for information regarding depreciation and estimated service lives of the property, plant, and equipment of the Registrants.

Retirement Benefits (All Registrants)

Exelon sponsors defined benefit pension plans and OPEB plans. The measurement of the plan obligations and costs of providing benefits involves various factors, including the development of valuation
assumptions and inputs and accounting policy elections. When developing the required assumptions, Exelon considers historical information as well as future expectations. The measurement of benefit
obligations and costs is affected by several assumptions including the discount rate, the long-term expected rate of return on plan assets, the anticipated rate of increase of health care costs, Exelon's
contributions, the rate of compensation increases, and the long-term expected investment rate credited to employees of certain plans, among others. The assumptions are updated annually and upon any
interim remeasurement of the plan obligations.

Pension  and  OPEB  plan  assets  include  cash  and  cash  equivalents,  equity  securities,  including  U.S.  and  international  securities,  and  fixed  income  securities,  as  well  as  certain  alternative  investment
classes such as real estate, private equity, private credit, and hedge funds.

Expected Rate of Return on Plan Assets. In determining the EROA, Exelon considers historical economic indicators (including inflation and GDP growth) that impact asset returns, as well as expectation
regarding  future  long-term  capital  market  performance,  weighted  by  Exelon’s  target  asset  class  allocations.  Exelon  calculates  the  amount  of  expected  return  on  pension  and  OPEB  plan  assets  by
multiplying the EROA by the MRV of plan assets at the beginning of the year, taking into consideration anticipated contributions and benefit payments to be made during the year. In determining MRV, the
authoritative guidance for pensions and postretirement benefits allows the use of either fair value or a calculated value that recognizes changes in fair value in a systematic and rational manner over not
more  than  five  years.  For  the  majority  of  pension  plan  assets,  Exelon  uses  a  calculated  value  that  adjusts  for  20%  of  the  difference  between  fair  value  and  expected  MRV  of  plan  assets.  Use  of  this
calculated value approach enables less volatile expected asset returns to be recognized as a component of pension cost from year to year. For OPEB plan assets and certain pension plan assets, Exelon
uses fair value to calculate the MRV.

Discount Rate. The discount rates are determined by developing a spot rate curve based on the yield to maturity of a universe of high-quality non-callable (or callable with make whole provisions) bonds
with similar maturities to the related pension and OPEB obligations. The spot rates are used to discount the estimated future benefit distribution amounts under the pension and OPEB plans. The discount
rate is the single level rate that produces the same result as the spot rate curve. Exelon utilizes an analytical tool developed by its actuaries to determine the discount rates.

Mortality. The mortality assumption is composed of a base table that represents the current expectation of life expectancy of the population adjusted by an improvement scale that attempts to anticipate
future improvements in life expectancy. Exelon’s mortality assumption utilizes the SOA 2019 base table (Pri-2012) and MP-2021 improvement scale adjusted to use Proxy SSA ultimate improvement rates.

In general, the discount rate will have a larger impact on the pension and OPEB cost and obligation as the rate moves closer to 0%. Therefore, the discount rate sensitivities above cannot necessarily be extrapolated for
larger increases or decreases in the discount rate. Additionally, Exelon utilizes a liability-driven investment strategy for its pension asset portfolio. The sensitivities shown above do not reflect the offsetting impact that
changes in discount rates may have on pension asset returns.

See Note 1 — Significant Accounting Policies and Note 14 — Retirement Benefits of the Combined Notes to Consolidated Financial Statements for additional information regarding the accounting for the
defined benefit pension plans and OPEB plans.

Regulatory Accounting (All Registrants)

For their regulated electric and gas operations, the Registrants reflect the effects of cost-based rate regulation in their financial statements, which is required for entities with regulated operations that meet
the following criteria: (1) rates are established or approved by a third-party regulator; (2) rates are designed to recover the entities’ cost of providing services or products; and (3) a reasonable expectation
that rates designed to recover costs can be charged to and collected from customers. Regulatory assets represent incurred costs that have been deferred because of their probable future recovery from
customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such amounts will be returned to customers through future regulated
rates; or (2) billings in advance of expenditures for approved regulatory programs. If it is concluded in a future period that a separable portion of operations no longer meets the criteria discussed above, the
Registrants would be required to eliminate any associated regulatory assets and liabilities and the impact, which could be material, would be recognized in the Consolidated Statements of Operations and
Comprehensive Income.

The  following  table  illustrates  gains  (losses)  to  be  included  in  net  income  that  could  result  from  the  elimination  of  regulatory  assets  and  liabilities  and  charges  against  OCI  related  to  deferred  costs
associated with Exelon's pension and OPEB plans that are recorded as Regulatory assets in Exelon's Consolidated Balance Sheets (before taxes) at December 31, 2023:

See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information regarding regulatory matters, including the regulatory assets and liabilities of the
Registrants.

For each regulatory jurisdiction in which they conduct business, the Registrants assess whether the regulatory assets and liabilities continue to meet the criteria for probable future recovery or refund at
each balance sheet date and when regulatory events occur. This assessment includes consideration of recent rate orders, historical regulatory treatment for similar costs in each Registrant's jurisdictions,
and factors such as changes in applicable regulatory and political environments. If the assessments and estimates made by the Registrants for regulatory assets and regulatory liabilities are ultimately
different than actual regulatory outcomes, the impact in their consolidated financial statements could be material.

Refer to the revenue recognition discussion below for additional information on the annual revenue reconciliations associated with ICC-approved electric distribution and energy efficiency formula rates for
ComEd, and FERC transmission formula rate tariffs for the Utility Registrants.

Derivative Financial Instruments (All Registrants)

The Registrants use derivative instruments to manage commodity price risk and interest rate risk related to ongoing business operations. See Note 15 — Derivative Financial Instruments of the Combined
Notes to Consolidated Financial Statements for additional information.

Determining whether a contract qualifies as a derivative requires that management exercise significant judgment, including assessing market liquidity as well as determining whether a contract has one or
more underlying and one or more notional quantities.

All derivatives are recognized on the balance sheet at their fair value, except for certain derivatives that qualify for, and are elected under, NPNS. For derivatives that qualify and are designated as cash
flow  hedges,  changes  in  fair  value  each  period  are  initially  recorded  in AOCI  and  recognized  in  earnings  when  the  hedged  transaction  affects  earnings.  For  derivatives  intended  to  serve  as  economic
hedges, which are not designated for hedge accounting, changes in fair value each period are recognized in earnings on the Consolidated Statement of Operations and Comprehensive Income or are
recorded as a regulatory asset or liability when there is an ability to recover or return the associated costs or benefits in accordance with regulatory requirements.

NPNS. Contracts  that  are  designated  as  NPNS  are  not  required  to  be  recorded  at  fair  value,  but  rather  on  an  accrual  basis  of  accounting.  Determining  whether  a  contract  qualifies  for  NPNS  requires
judgment on whether the contract will physically deliver and requires that management ensure compliance with all the associated qualification and documentation requirements. For all NPNS derivative
instruments, accounts payable is recorded when derivatives settle and expense is recognized in earnings as the underlying physical commodity is consumed. Contracts that qualify for NPNS are those for
which physical delivery is probable, quantities are expected to be used or sold in the normal course of business over a reasonable period, and the contract is not financially settled on a net basis. See Note
15 — Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for all contracts that are accounted for under NPNS.

Commodity  Contracts. The  Registrants  make  estimates  and  assumptions  concerning  future  commodity  prices,  interest  rates,  and  the  timing  of  future  transactions  and  their  probable  cash  flows  in
deciding whether to enter derivative transactions, and in determining the initial accounting treatment for derivative transactions. The Registrants categorize these derivatives under a fair value hierarchy
that prioritizes the inputs to valuation techniques used to measure fair value.

Derivative contracts can be traded in both exchange-based and non-exchange-based markets. Exchange-based derivatives that are valued using unadjusted quoted prices in active markets are generally
categorized in Level 1 in the fair value hierarchy. Certain derivative pricing is verified using indicative price quotations available through brokers or over-the-counter, online exchanges. For derivatives that
trade in liquid markets, the model inputs are generally observable. Such instruments are categorized in Level 2. For derivatives that trade in less liquid markets with limited pricing information, the model
inputs generally would include both observable and unobservable inputs and are categorized in Level 3.

The  Registrants  consider  nonperformance  risk,  including  credit  risk  in  the  valuation  of  derivative  contracts,  and  both  historical  and  current  market  data  in  the  assessment  of  nonperformance  risk.  The
impacts of nonperformance and credit risk to date have generally not been material to the Registrants’ financial statements.

Interest Rate Derivative Instruments. Exelon Corporate utilizes interest rate swaps to manage interest rate risk on existing and planned future debt issuances as well as potential fluctuations in Electric
operating revenues at the corporate level in consolidation, which are directly correlated to yields on U.S. Treasury bonds under ComEd's distribution formula rate. The fair value of the swaps is calculated
by discounting the future net cash flows to the present value based on the terms and conditions of the agreements and the forward interest rate curves. As these inputs are based on observable data and
valuations of similar instruments, the interest rate derivatives are primarily categorized in Level 2 in the fair value hierarchy.

See ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK and Note 17 — Fair Value of Financial Assets and Liabilities and Note 15 — Derivative Financial Instruments
of the Combined Notes to Consolidated Financial Statements for additional information regarding the Registrants’ derivative instruments.

Income Taxes (All Registrants)

Significant management judgment is required in determining the Registrants’ provisions for income taxes, primarily due to the uncertainty related to tax positions taken, as well as deferred tax assets and
liabilities  and  valuation  allowances.  The  Registrants  account  for  uncertain  income  tax  positions  using  a  benefit  recognition  model  with  a  two-step  approach  including  a  more-likely-than-not  recognition
threshold and a measurement approach based on the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement. Management evaluates each position based
solely  on  the  technical  merits  and  facts  and  circumstances  of  the  position,  assuming  the  position  will  be  examined  by  a  taxing  authority  having  full  knowledge  of  all  relevant  information.  Significant
judgment is required to determine whether the recognition threshold has been met and, if so, the appropriate amount of tax benefits to be recorded in the Registrants’ consolidated financial statements.

The  Registrants  evaluate  quarterly  the  probability  of  realizing  deferred  tax  assets  by  reviewing  a  forecast  of  future  taxable  income  and  their  intent  and  ability  to  implement  tax  planning  strategies,  if
necessary, to realize deferred tax assets. The Registrants also assess negative evidence, such as the expiration of historical operating loss or tax credit carryforwards, that could indicate the Registrant's
inability to realize its deferred tax assets. Based on the combined assessment, the Registrants record valuation allowances for deferred tax assets when it is more-likely-than-not such benefit will not be
realized in future periods.

Actual income taxes could vary from estimated amounts due to the future impacts of various items, including future changes in income tax laws, the Registrants’ forecasted financial condition and results of
operations, failure to successfully implement tax planning strategies, as well as results of audits and examinations of filed tax returns by taxing authorities. See Note 13 — Income Taxes of the Combined
Notes to Consolidated Financial Statements for additional information.

Accounting for Loss Contingencies (All Registrants)

In the preparation of their financial statements, the Registrants make judgments regarding the future outcome of contingent events and record liabilities for loss contingencies that are probable and can be
reasonably estimated based upon available information. The amount recorded may differ from the actual expense incurred when the uncertainty is resolved. Such difference could have a significant impact
in the Registrants' consolidated financial statements.

Environmental Costs. Environmental investigation and remediation liabilities are based upon estimates with respect to the number of sites for which the Registrants will be responsible, the scope and cost
of work to be performed at each site, the portion of costs that will be shared with other parties, the timing of the remediation work, regulations, and the requirements of local governmental authorities.
Annual studies and/or reviews are conducted at ComEd, PECO, BGE, and DPL to determine future remediation requirements for MGP sites and estimates are adjusted accordingly. In addition, periodic
reviews  are  performed  at  each  of  the  Registrants  to  assess  the  adequacy  of  other  environmental  reserves.  These  matters,  if  resolved  in  a  manner  different  from  the  estimate,  could  have  a  significant
impact in the Registrants’ consolidated financial statements. See Note 18 — Commitments and Contingencies of the Combined Notes to Consolidated Financial Statements for additional information.

Other, Including Personal Injury Claims. The Registrants are self-insured for general liability, automotive liability, workers’ compensation, and personal injury claims to the extent that losses are within
policy deductibles

52

Table of Contents

or exceed the amount of insurance maintained. The Registrants have reserves for both open claims asserted, and an estimate of claims incurred but not reported (IBNR). The IBNR reserve is estimated
based  on  actuarial  assumptions  and  analysis  and  is  updated  annually.  Future  events,  such  as  the  number  of  new  claims  to  be  filed  each  year,  the  average  cost  of  disposing  of  claims,  as  well  as  the
numerous uncertainties surrounding litigation and possible state and national legislative measures could cause the actual costs to be higher or lower than estimated. Accordingly, these claims, if resolved
in a manner different from the estimate, could have a material impact to the Registrants’ consolidated financial statements.

Revenues (All Registrants)

Sources of Revenue and Determination of Accounting Treatment. The Registrants earn revenues from the sale and delivery of power and natural gas in regulated markets. The accounting treatment
for  revenue  recognition  is  based  on  the  nature  of  the  underlying  transaction  and  applicable  authoritative  guidance.  The  Registrants  primarily  apply  the  Revenue  from  Contracts  with  Customers,  and
Alternative Revenue Program accounting guidance to recognize revenues as discussed in more detail below.

Revenue from Contracts with Customers. The Registrants recognize revenues in the period in which the performance obligations within contracts with customers are satisfied, which generally occurs
when  power  and  natural  gas  are  physically  delivered  to  the  customer.  Transactions  of  the  Registrants  within  the  scope  of  Revenue  from  Contracts  with  Customers  generally  include  sales  to  utility
customers under regulated service tariffs.

The determination of the Registrants' power and natural gas sales to individual customers is based on systematic readings of customer meters, generally monthly. At the end of each month, amounts of
energy delivered to customers since the date of the last meter reading are estimated, and corresponding unbilled revenue is recorded. The measurement of unbilled revenue is affected by the following
factors: daily customer usage measured  by  generation  or  gas  throughput  volume,  customer  usage  by  class,  losses  of  energy  during  delivery  to  customers  and  applicable  customer  rates.  Increases  or
decreases  in  volumes  delivered  to  the  Registrant’s  customers  and  favorable  or  unfavorable  rate  mix  due  to  changes  in  usage  patterns  in  customer  classes  in  the  period  could  be  significant  to  the
calculation of unbilled revenue. In addition, revenues may fluctuate monthly as a result of customers electing to use an alternative supplier, since unbilled commodity revenues are not recorded for these
customers. Changes in the timing of meter reading schedules and the number and type of customers scheduled for each meter reading date also impact the measurement of unbilled revenue; however,
total operating revenues would remain materially unchanged. See Note 1 — Significant Accounting Policies of the Combined Notes to Consolidated Financial Statements for additional information.

Alternative  Revenue  Program  Accounting. Certain of the Registrants’ ratemaking mechanisms qualify as ARPs if they (i) are established by a regulatory order and allow for automatic adjustment to
future  rates,  (ii)  provide  for  additional  revenues  (above  those  amounts  currently  reflected  in  the  price  of  utility  service)  that  are  objectively  determinable  and  probable  of  recovery,  and  (iii)  allow  for  the
collection of those additional revenues within 24 months following the end of the period in which they were recognized. For mechanisms that meet these criteria, which include the Registrants’ formula rate
mechanisms and revenue decoupling mechanisms, the Registrants adjust revenue and record an offsetting regulatory asset or liability once the condition or event allowing additional billing or refund has
occurred. The ARP revenues presented in the Registrants’ Consolidated Statements of Operations and Comprehensive Income include both: (i) the recognition of “originating” ARP revenues (when the
regulator-specified condition or event allowing for additional billing or refund has occurred) and (ii) an equal and offsetting reversal of the “originating” ARP revenues as those amounts are reflected in the
price of utility service and recognized as Revenue from Contracts with Customers.

ComEd records ARP revenue for its best estimate of the electric distribution, energy efficiency, distributed generation rebates, and transmission revenue impacts resulting from future changes in rates that
ComEd believes are probable of approval by the ICC and FERC in accordance with its formula rate mechanisms. BGE, Pepco, DPL, and ACE record ARP revenue for their best estimate of the electric and
natural  gas  distribution  revenue  impacts  resulting  from  future  changes  in  rates  that  they  believe  are  probable  of  approval  by  the  MDPSC,  DCPSC,  and/or  NJBPU  in  accordance  with  their  revenue
decoupling mechanisms. PECO, BGE, Pepco, DPL, and ACE record ARP revenue for their best estimate of the transmission revenue impacts resulting from future changes in rates that they believe are
probable of approval by FERC in accordance with their formula rate mechanisms. Estimates of the current year revenue requirement are based on actual and/or forecasted costs and investments in rate
base for the period and the rates of return on common equity and associated regulatory

53

capital  structure  allowed  under  the  applicable  tariff.  The  estimated  reconciliation  can  be  affected  by,  among  other  things,  variances  in  costs  incurred,  investments  made,  allowed  ROE,  and  actions  by
regulators or courts.

See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information.

Allowance for Credit Losses on Customer Accounts Receivable (All Registrants)

The Registrants estimate the allowance for credit losses on customer receivables by applying loss rates developed specifically for each company based on historical loss experience, current conditions,
and forward-looking risk factors to the outstanding receivable balance by customer risk segment. Risk segments represent a group of customers with similar forward-looking credit quality indicators and risk
factors that are comprised based on various attributes, including delinquency of their balances and payment history and represent expected, future customer behavior. Loss rates applied to the accounts
receivable balances are based on a historical average of charge-offs as a percentage of accounts receivable in each risk segment. The Registrants' customer accounts are generally considered delinquent
if the amount billed is not received by the time the next bill is issued, which normally occurs on a monthly basis. The Registrants' customer accounts are written off consistent with approved regulatory
requirements.  The  Registrants'  allowances  for  credit  losses  will  continue  to  be  affected  by  changes  in  volume,  prices,  and  economic  conditions  as  well  as  changes  in  ICC,  PAPUC,  MDPSC,  DCPSC,
DEPSC, and NJBPU regulations.

Year Ended December 31, 2023 Compared to Year Ended December 31, 2022. Net income increased by $173 million primarily due to increases in electric distribution formula rate earnings (reflecting
higher allowed ROE due to an increase in U.S. Treasury rates and the impacts of higher rate base) and carrying costs related to CMC regulatory assets.

Revenue Decoupling. The demand for electricity is affected by weather and customer usage. Operating revenues are not impacted by abnormal weather, usage per customer, or number of customers as
a result of revenue decoupling mechanisms implemented pursuant to FEJA.

Distribution  Revenue. EIMA  and  FEJA  provide  for  a  performance-based  formula  rate,  which  requires  an  annual  reconciliation  of  the  revenue  requirement  in  effect  to  the  actual  costs  that  the  ICC
determines are prudently and reasonably incurred in a given year. Electric distribution revenue varies from year to year based upon fluctuations in the underlying costs (e.g., severe weather and storm
restoration),  investments  being  recovered,  and  allowed  ROE.  Electric  distribution  revenue  increased  during  the  year  ended  December  31,  2023,  compared  to  the  same  period  in  2022,  due  to  higher
allowed ROE due to an increase in U.S. Treasury rates, the impact of a higher rate base, and higher fully recoverable costs.

55

Table of Contents

ComEd

Transmission Revenue. Under a FERC-approved formula, transmission revenue varies from year to year based upon fluctuations in the underlying costs, capital investments being recovered,  and  the
highest  daily  peak  load,  which  is  updated  annually  in  January  based  on  the  prior  calendar  year.  Generally,  increases/decreases  in  the  highest  daily  peak  load  will  result  in  higher/lower  transmission
revenue. Transmission revenues increased during the year ended December 31, 2023, compared to the same period in 2022, primarily due to the impact of a higher rate base and higher fully recoverable
costs.

Energy Efficiency Revenue. FEJA provides for a performance-based formula rate, which requires an annual reconciliation of the revenue requirement in effect to the actual costs that the ICC determines
are prudently and reasonably incurred in a given year. Under FEJA, energy efficiency revenue varies from year to year based upon fluctuations in the underlying costs, investments being recovered, and
allowed  ROE.  Energy  efficiency  revenue increased during the year ended December 31, 2023, compared to the same period in 2022, primarily due to the impact of a higher rate base, and increased
regulatory asset amortization, which is fully recoverable.

Other Revenue primarily includes assistance provided to other utilities through mutual assistance programs. Other revenue increased for the year ended December 31, 2023, compared to the same period
in 2022, which primarily reflects mutual assistance revenues associated with storm restoration efforts.

Regulatory  Required  Programs  represents  revenues  collected  under  approved  riders  to  recover  costs  incurred  for  regulatory  programs  such  as  recoveries  under  the  credit  loss  expense  tariff,
environmental  costs  associated  with  MGP  sites,  ETAC,  and  costs  related  to  electricity,  ZEC,  CMC,  and  REC  procurement.  See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information regarding CMCs. ETAC is a retail customer surcharge collected by electric utilities operating in Illinois established by CEJA and remitted to an Illinois state
agency for programs to support clean energy jobs and training. The riders are designed to provide full and current cost recovery. The costs of these programs are included in Purchased power expense,
Operating  and  maintenance  expense,  Depreciation  and  amortization  expense,  and  Taxes  other  than  income.  Customers  have  the  choice  to  purchase  electricity  from  competitive  electric  generation
suppliers. Customer choice programs do not impact the volume of deliveries as ComEd remains the distribution service provider for all customers and charges a regulated rate for distribution service, which
is recorded in Operating revenues. For customers that choose to purchase electric generation from competitive suppliers, ComEd either acts as the billing agent or the competitive supplier separately bills
its  own  customers,  and  therefore  does  not  record  Operating  revenues  or  Purchased  power  expense  related  to  the  electricity.  For  customers  that  choose  to  purchase  electric  generation  from  ComEd,
ComEd is permitted to recover the electricity, ZEC, CMC, and REC procurement costs without mark-up and therefore records equal and offsetting amounts in Operating revenues and Purchased power
expense related to the electricity, ZECs, CMCs, and RECs.

See Note 5 — Segment Information of the Combined Notes to Consolidated Financial Statements for the presentation of ComEd's revenue disaggregation.

The increase of $1,707 million for the year ended December 31, 2023, compared to the same period in 2022, in Purchased power expense is primarily due to the CMCs from the participating nuclear-
powered  generating  facilities,  which  is  offset  by  an  increase  in  Operating  revenues  as  part  of  regulatory  required  programs.  See  Note  3  -  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information regarding CMCs.

Weather. The demand for electricity and natural gas is affected by weather conditions. With respect to the electric business, very warm weather in summer months and, with respect to the electric and
natural gas businesses, very cold weather in winter months are referred to as “favorable weather conditions” because these weather conditions result in increased deliveries of electricity and natural gas.
Conversely,  mild  weather  reduces  demand.  For  the  year  ended  December  31,  2023  compared  to  the  same  period  in  2022,  Operating  revenues  related  to  weather  decreased  due  to  the  impact  of
unfavorable weather conditions in PECO's service territory.

Heating and cooling degree days are quantitative indices that reflect the demand for energy needed to heat or cool a home or business. Normal weather is determined based on historical average heating
and cooling degree days for a 30-year period in PECO’s service territory. The changes in heating and cooling degree days in PECO’s service territory for the years ended December 31, 2023 compared to
the same period in 2022 and normal weather consisted of the following:

PECO

Transmission Revenue. Under a FERC-approved formula, transmission revenue varies from year to year based upon fluctuations in the underlying costs and capital investments being recovered.

Other Revenue primarily includes revenue related to late payment charges. Other revenues for the year ended December 31, 2023 compared to the same period in 2022, remained relatively consistent.

Regulatory Required Programs  represents  revenues  collected  under  approved  riders  to  recover  costs  incurred  for  regulatory  programs  such  as  energy  efficiency,  PGC,  and  the  GSA.  The  riders  are
designed to provide full and current cost recovery as well as a return. The costs of these programs are included in Purchased power and fuel expense, Operating and maintenance expense, Depreciation
and amortization expense, and Income taxes. Customers have the choice to purchase electricity and natural gas from competitive electric generation and natural gas suppliers. Customer choice programs
do not impact the volume of deliveries as PECO remains the distribution service provider for all customers and charges a regulated rate for distribution service, which is recorded in Operating revenues. For
customers that choose to purchase electric generation or natural gas from competitive suppliers, PECO either acts as the billing agent or the competitive supplier separately bills its own customers and
therefore PECO does not record Operating revenues or Purchased power and fuel expense related to the electricity and/or natural gas. For customers that choose to purchase electric generation or natural
gas from PECO, PECO is permitted to recover the electricity, natural gas, and REC procurement costs without mark-up and therefore records equal and offsetting amounts in Operating revenues and
Purchased power and fuel expense related to the electricity, natural gas, and RECs.

See Note 5 — Segment Information of the Combined Notes to Consolidated Financial Statements for the presentation of PECO's revenue disaggregation.

The increase of $9 million for the year ended December 31, 2023, compared to the same period in 2022, in Purchased power and fuel expense is fully offset in Operating revenues as part of regulatory
required programs.

Revenue Decoupling. The demand for electricity and natural gas is affected by weather and customer usage. However, Operating revenues are not impacted by abnormal weather or usage per customer
as  a  result  of  a  monthly  rate  adjustment  that  provides  for  fixed  distribution  revenue  per  customer  by  customer  class.  While  Operating  revenues  are  not  impacted  by  abnormal  weather  or  usage  per
customer, they are impacted by changes in the number of customers. See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information on revenue

Revenue Decoupling. The demand for electricity is affected by weather and customer usage. However, Operating revenues from electric distribution in Maryland are not impacted by abnormal weather or
usage per customer as a result of a BSA that provides for a fixed distribution charge per customer by customer class. While Operating revenues from electric distribution customers in Maryland are not
impacted by abnormal weather or usage per customer, they are impacted by changes in the number of customers. See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial
Statements for additional information on revenue decoupling for DPL Maryland.

Weather. The demand for electricity and natural gas in Delaware is affected by weather conditions. With respect to the electric business, very warm weather in summer months and, with respect to the
electric and natural gas businesses, very cold weather in winter months are referred to as "favorable weather conditions” because these weather conditions result in increased deliveries of electricity and
natural gas. Conversely, mild weather reduces demand. During the year ended December 31, 2023 compared to the same period in 2022, Operating revenues

Heating and cooling degree days are quantitative indices that reflect the demand for energy needed to heat or cool a home or business. Normal weather is determined based on historical average heating
and cooling degree days for a 20-year period in DPL's Delaware electric service territory and a 30-year period in DPL's Delaware natural gas service territory. The changes in heating and cooling degree

Distribution  Revenue increased  for  the  year  ended  December  31,  2023  compared  to  the  same  period  in  2022  primarily  due  favorable  impacts  of  the  Maryland  multi-year  plan  that  became  effective
January 2023, favorable impacts of the higher electric distribution rates in Delaware that became effective July 2023, and higher natural gas distribution rates effective in August 2022.

Transmission  Revenue. Under  a  FERC-approved  formula,  transmission  revenue  varies  from  year  to  year  based  upon  fluctuations  in  the  underlying  costs  and  capital  investments  being  recovered.
Transmission revenue increased for the year ended December 31, 2023 compared to the same period in 2022 primarily due to increases in underlying costs and capital investment.

Other Revenue includes rental revenue, revenue related to late payment charges, mutual assistance revenues, and recoveries of other taxes.

Regulatory  Required  Programs  represent  revenues  collected  under  approved  riders  to  recover  costs  incurred  for  regulatory  programs  such  as  energy  efficiency  programs,  DE  Renewable  Portfolio
Standards,  SOS  procurement  and  administrative  costs,  and  GCR  costs.  The  riders  are  designed  to  provide  full  and  current  cost  recovery  as  well  as  a  return  in  certain  instances.  The  costs  of  these
programs are included in Purchased power and fuel expense, Operating and maintenance expense, Depreciation and amortization expense, and Taxes other than income taxes. All customers have the
choice to purchase electricity from competitive electric generation suppliers; however, only certain commercial and industrial customers have the choice to purchase natural gas from competitive natural
gas suppliers. Customer choice programs do not impact the volume of deliveries as DPL remains the distribution service provider for all customers and charges a regulated rate for distribution service,
which  is  recorded  in  Operating  revenues.  For  customers  that  choose  to  purchase  electric  generation  or  natural  gas  from  competitive  suppliers,  DPL  either  acts  as  the  billing  agent  or  the  competitive
supplier separately bills its own customers, and therefore does not record Operating revenues or Purchased power and fuel expense related to the electricity and/or natural gas. For customers that choose
to purchase electric generation or natural gas from DPL, DPL is permitted to recover the electricity, natural gas, and REC procurement costs from customers and therefore records the amounts related to
the  electricity,  natural  gas,  and  RECs  in  Operating  revenues  and  Purchased  power  and  fuel  expense.  DPL  recovers  electricity  and  REC  procurement  costs  from  customers  with  a  slight  mark-up,  and
natural gas costs without mark-up.

See Note 5 — Segment Information of the Combined Notes to Consolidated Financial Statements for the presentation of DPL's revenue disaggregation.

The increase of $31 million for the year ended December 31, 2023 compared to the same period in 2022, in Purchased power and fuel expense is fully offset in Operating revenues as part of regulatory
required programs.

Revenue Decoupling. The demand for electricity is affected by weather and customer usage. However, Operating revenues from electric distribution in New Jersey are not impacted by abnormal weather
or usage per customer as a result of the CIP which became effective, prospectively, in the third quarter of 2021. The CIP compares current distribution revenues by customer class to approved target
revenues established in ACE’s most recent distribution base rate case. The CIP is calculated annually, and recovery is subject to certain conditions, including an earnings test and ceilings on customer rate
increases. While Operating revenues are not impacted by abnormal weather or usage per customer, they are impacted by changes in the number of customers. See Note 3 — Regulatory Matters of the
Combined Notes to the Consolidated Financial Statements for additional information on the ACE CIP.

Distribution Revenue increased for the year ended December 31, 2023 compared to the same period in 2022 due to higher distribution rates primarily due to the expiration of customer credits related to
the TCJA tax benefits.

Transmission  Revenue. Under  a  FERC-approved  formula,  transmission  revenue  varies  from  year  to  year  based  upon  fluctuations  in  the  underlying  costs  and  capital  investments  being  recovered.
Transmission revenue increased for the year ended December 31, 2023 compared to the same period in 2022 primarily due to increases in capital investment and underlying costs.

Other Revenue includes rental revenue, service connection fees, and mutual assistance revenues.

Regulatory Required Programs  represent  revenues  collected  under  approved  riders  to  recover  costs  incurred  for  regulatory  programs  such  as  energy  efficiency  programs,  Societal  Benefits  Charge,
Transition Bonds, and BGS procurement and administrative costs. The riders are designed to provide full and current cost recovery as well as a return in certain instances. The costs of these programs are
included  in  Purchased  power  expense,  Operating  and  maintenance  expense,  Depreciation  and  amortization  expense,  and  Taxes  other  than  income  taxes.  Customers  have  the  choice  to  purchase
electricity from competitive electric generation suppliers. Customer choice programs do not impact the volume of deliveries, as ACE remains the distribution service provider for all customers and charges a

therefore, ACE  does  not  record  Operating  revenues  or  Purchased  power  expense  related  to  the  electricity.  For  customers  that  choose  to  purchase  electric  generation  from ACE, ACE  is  permitted  to
recover  the  electricity,  ZEC,  and  REC  procurement  costs  without  mark-up  and  therefore  records  equal  and  offsetting  amounts  in  Operating  revenues  and  Purchased  power  expense  related  to  the
electricity, ZECs, and RECs.

Liquidity and Capital Resources

All results included throughout the liquidity and capital resources section are presented on a GAAP basis.

The Registrants’ operating and capital expenditures requirements are provided by internally generated cash flows from operations, as well as funds from external sources in the capital markets and through
bank borrowings. The Registrants’ businesses are capital intensive and require considerable capital resources. Each of the Registrants annually evaluates its financing plan, dividend practices, and credit
line sizing, focusing on maintaining its investment grade ratings while meeting its cash needs to fund capital requirements, including construction expenditures, retire debt, pay dividends, and fund pension
and  OPEB  obligations.  The  Registrants  spend  a  significant  amount  of  cash  on  capital  improvements  and  construction  projects  that  have  a  long-term  return  on  investment.  Additionally,  the  Utility
Registrants operate in rate-regulated environments in which the amount of new investment recovery may be delayed or limited and where such recovery takes place over an extended period of time. Each
Registrant’s access to external financing on reasonable terms depends on its credit ratings and current overall capital market business conditions, including that of the utility industry in general. If these
conditions deteriorate to the extent that the Registrants no longer have access to the capital markets at reasonable terms, the Registrants have access to credit facilities with aggregate bank commitments
of $4.0 billion, as of December 31, 2023. The Registrants utilize their credit facilities to support their commercial paper programs, provide for other short-term borrowings, and to issue letters of credit. See
the  “Credit  Matters  and  Cash  Requirements”  section  below  for  additional  information.  The  Registrants  expect  cash  flows  to  be  sufficient  to  meet  operating  expenses,  financing  costs,  and  capital
expenditure  requirements.  See  Note  16  —  Debt  and  Credit Agreements  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  on  the  Registrants’  debt  and  credit
agreements.

Cash flows related to Generation have not been presented as discontinued operations and are included in the Consolidated Statements of Cash Flows for all periods presented. The Exelon Consolidated
Statement  of  Cash  Flows  for  the  year  ended  December  31,  2023  includes  no  cash  flows  from  Generation.  The  Exelon  Consolidated  Statement  of  Cash  Flows  for  the  year  ended  December  31,  2022
includes one months of cash flows from Generation. See below for additional reasons for the changes in cash flows.

Cash Flows from Operating Activities

The Utility Registrants' cash flows from operating activities primarily result from the transmission and distribution of electricity and, in the case of PECO, BGE, and DPL, gas distribution services. The Utility
Registrants' distribution services are provided to an established and diverse base of retail customers. The Utility Registrants' future cash flows may be affected by the economy, weather conditions, future
legislative initiatives, future

regulatory proceedings with respect to their rates or operations, and their ability to achieve operating cost reductions. Additionally, ComEd is required to purchase CMCs from participating nuclear-powered
generating facilities for a five-year period, and all of its costs of doing so will be recovered through a new rider. The price to be paid for each CMC is established through a competitive bidding process.
ComEd  will  provide  net  payments  to,  or  collect  net  payments  from,  customers  for  the  difference  between  customer  credits  issued  and  the  credit  to  be  received  from  the  participating  nuclear-powered
generating facilities. ComEd’s cash flows are affected by the establishment of CMC prices and the timing of recovering costs through the CMC regulatory asset.

See  Note  3  —  Regulatory  Matters  and  Note  18  —  Commitments  and  Contingencies  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  on  regulatory  and  legal
proceedings and proposed legislation.

Changes  in  the  Registrants'  cash  flows  from  operations  were  generally  consistent  with  changes  in  each  Registrant’s  respective  results  of  operations,  as  adjusted  by  changes  in  working  capital  in  the
normal  course  of  business,  except  as  discussed  below.  See  above  for  additional  information  related  to  cash  flows  from  Generation.  Significant  operating  cash  flow  impacts  for  the  Registrants  and
Generation for the years ended December 31, 2023 and 2022 were as follows:

See Note 22 —Supplemental Financial Information of the Combined Notes to Consolidated Financial Statements and the Registrants’ Consolidated Statements of Cash Flows for additional
information on non-cash operating activities.

Changes in collateral depended upon whether the Registrant was in a net mark-to-market liability or asset position, and collateral may have been required to be posted with or collected from
its  counterparties. In  addition,  the  collateral  posting  and  collection  requirements  differed  depending  on  whether  the  transactions  were  on  an  exchange  or  in  the  over-the-counter  markets.
Changes in collateral for the Utility Registrants are dependent upon the credit exposure of procurement contracts that may require suppliers to post collateral. The amount of cash collateral
received from external counterparties increased due to rising energy prices. See Note 15 — Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for
additional information.

See Note 13 — Income Taxes of the Combined Notes to Consolidated Financial Statements and the Registrants' Consolidated Statements of Cash Flows for additional information on income
taxes.

Changes  in Pension  and  non-pension  postretirement  benefit  contributions  relate  to  Exelon's  funding  strategy  and  incremental  contributions  made  in  2022  in  connection  with  the
separation. See Note 14 — Retirement Benefits

Changes in Regulatory assets and liabilities, net, are due to the timing of cash payments for costs recoverable, or cash receipts for costs recovered, under our regulatory mechanisms
differs from the recovery period of those costs. Included within the changes is energy efficiency spend for ComEd of $416 million and $394 million for the years ended December 31, 2023 and
2022, respectively. Also included within the changes is energy efficiency and demand response programs spend for BGE, Pepco, DPL, and ACE of $132 million, $70 million, $25 million, and
$20 million for the year ended December 31, 2023, respectively, and $113 million, $71 million, $28 million, and $11 million for the year ended December 31, 2022, respectively. PECO had no
energy  efficiency  and  demand  response  programs  spend  recorded  to  a  regulatory  asset  for  the  years  ended  December  31,  2023  and  2022.  See  Note  3  —  Regulatory  Matters  of  the
Combined Notes to Consolidated Financial Statements for additional information.

Changes  in  working  capital  and  other  noncurrent  assets  and  liabilities  for  the  Utility  Registrants  and  Exelon  Corporate  total  $146  million  and  for  Generation  total  $323  million.  The
change  for  Generation  primarily  relates  to  the  revolving  accounts  receivable  financing  arrangement.  The  change  in  working  capital  and  other  noncurrent  assets  and  liabilities  for  Exelon
Corporate and the Utility Registrants is dependent upon the normal course of operations for all Registrants. For ComEd, it is also dependent upon whether the participating nuclear-powered
generating facilities owe money to ComEd as a result of the established pricing for CMCs. For the year ended December 31, 2023, the established pricing resulted in ComEd owing payments
to nuclear-powered generating facilities, which is reported within the cash flows from operations as a change in Accounts payable and accrued expense.

Changes in short-term borrowings, net, is driven by repayments on and issuances of notes due in less than 365 days. Refer to Note 16 — Debt and Credit Agreements of the Combined
Notes to Consolidated Financial Statements for additional information on Short-term borrowings for the Registrants.

Long-term debt, net, varies due to debt issuances and redemptions each year. Refer to the debt issuances and redemptions tables below for additional information for the Registrants.

Changes in intercompany money pool are driven by short-term borrowing needs. Refer below for more information regarding the intercompany money pool.

Issuance of common stock relates to the August 2022 underwritten public offering of Exelon common stock as well as 2023 issuances under the ATM program. See Note 19 — Shareholders'
Equity of the Combined Notes to Consolidated Financial Statements for additional information.

Exelon’s ability to pay dividends on its Common stock depends on the receipt of dividends paid by its operating subsidiaries. The payments of dividends to Exelon by its subsidiaries in turn
depend on their results of operations and cash flows and other items affecting Retained earnings. See Note 18 — Commitments and Contingencies of the Combined Notes to Consolidated
Financial Statements for additional information on dividend restrictions. See below for quarterly dividends declared.

Repayments on short-term borrowings, varies due to debt issuances and redemptions each year. Refer to Note 16 — Debt and Credit Agreements of the Combined Notes to Consolidated
Financial Statements for additional information on repayments on short-term borrowings for the Registrants.

Refer to Note 2 — Discontinued Operations for the Transfer of cash, restricted cash, and cash equivalents to Constellation related to the separation.

In connection with the issuance and sale of the Notes, Exelon entered into a Registration Rights Agreement with the representatives of the initial purchasers of the Notes and other parties. Pursuant to the Registration
Rights Agreement,  Exelon  filed  a  registration  statement  on August  3,  2022,  with  respect  to  an  offer  to  exchange  the  Notes  for  substantially  similar  notes  of  Exelon  that  are  registered  under  the  Securities Act. An
exchange offer of registered notes for the Notes was completed on January 12, 2023. The registered notes issued in exchange for Notes in the exchange offer have terms identical in all respects to the Notes, except
that their issuance was registered under the Securities Act.

(b) During the third quarter of 2022, the SMBC Term Loan, U.S. Bank Term Loan, and PNC Term Loan were all reclassified to Long-term debt due within one year on the Exelon Consolidated Balance Sheet, given that the

Additionally, in connection with the separation, on January 31, 2022, Exelon Corporate received cash from Generation of $258 million to settle an intercompany loan that mirrored the terms and amounts of
the third-party debt obligations. The loan agreements were entered into as part of the 2012 Constellation merger. See Note 16 — Debt and Credit Agreements of the Combined Notes to Consolidated
Financial Statements for additional information on the mirror debt.

From time to time and as market conditions warrant, the Registrants may engage in long-term debt retirements via tender offers, open market repurchases or other viable options to reduce debt on their
respective balance sheets.

Credit Matters and Cash Requirements

The  Registrants  fund  liquidity  needs  for  capital  expenditures,  working  capital,  energy  hedging,  and  other  financial  commitments  through  cash  flows  from  continuing  operations,  public  debt  offerings,
commercial paper markets, and large, diversified credit facilities. The credit facilities include $4.0 billion in aggregate total commitments of which $2.4 billion was available to support additional commercial
paper as of December 31, 2023, and of which no financial institution has more than 6% of the aggregate commitments for the Registrants. The Registrants had access to the commercial paper markets
and had availability under their revolving credit facilities during 2023 to fund their short-term liquidity needs, when necessary. Exelon Corporate and the Utility Registrants each have a 5-year revolving
credit facility. See Note 16 — Debt and Credit Agreements of the Combined Notes to Consolidated Financial Statements for additional information. The Registrants had access to the commercial paper
markets  and  had  availability  under  their  revolving  credit  facilities  during  2023  to  fund  their  short-term  liquidity  needs,  when  necessary.  The  Registrants  routinely  review  the  sufficiency  of  their  liquidity
position, including appropriate sizing of credit facility commitments, by performing various stress test scenarios, such as commodity price movements, increases in margin-related transactions, changes in
hedging levels, and the impacts of hypothetical credit downgrades. The Registrants closely monitor events in the financial markets and the financial institutions associated with the credit facilities, including
monitoring credit ratings and outlooks, credit default swap levels, capital raising, and merger activity. See PART I, ITEM 1A. RISK FACTORS for additional information regarding the effects of uncertainty in
the capital and credit markets.

The Registrants believe their cash flow from operating activities, access to credit markets, and their credit facilities provide sufficient liquidity to support the estimated future cash requirements discussed
below.

On August  4,  2022,  Exelon  entered  into  an  agreement  with  certain  underwriters  in  connection  with  an  underwritten  public  offering  of  12.995  million  shares  of  its  Common  stock,  no  par  value.  The  net
proceeds were $563 million before expenses paid. Exelon used the proceeds, together with available cash balances, to repay $575 million in borrowings under a $1.15 billion term loan credit facility. See
Note 19 — Shareholders' Equity and Note 16 — Debt and Credit Agreements of the Combined Notes to Consolidated Financial Statements for additional information.

On August 4, 2022, Exelon executed an equity distribution agreement (“Equity Distribution Agreement”) with certain sales agents and forward sellers and certain forward purchasers establishing an ATM
equity distribution program under which it may offer and sell shares of its Common stock, having an aggregate gross sales price of up to $1.0 billion. Exelon has no obligation to offer or sell any shares of
Common stock under the Equity Distribution Agreement and may at any time suspend or terminate offers and sales under the Equity Distribution Agreement. In November and December 2023, Exelon
issued approximately 3.6 million shares of Common stock at an average gross price of $39.58 per share. The net proceeds from these issuances were $140 million, which were used for general corporate
purposes. As of December 31, 2023, $858 million of Common stock remained available for sale pursuant to the ATM program.

Pursuant  to  the  Separation  Agreement  between  Exelon  and  Constellation  Energy  Corporation,  Exelon  made  a  cash  payment  of  $1.75  billion  to  Generation  on  January  31,  2022.  See  Note  2  —
Discontinued Operations of the Combined Notes to Consolidated Financial Statements for additional information on the separation.

The  following  table  presents  the  incremental  collateral  that  each  Utility  Registrant  would  have  been  required  to  provide  in  the  event  each  Utility  Registrant  lost  its  investment  grade  credit  rating  at

Includes estimated capital expenditures for the Utility Registrants from 2025 to 2027.

Projected capital expenditures and other investments are subject to periodic review and revision to reflect changes in economic conditions and other factors. Projected capital expenditures at the Utility
Registrants are for continuing projects to maintain and improve operations, including enhancing reliability and adding capacity to the transmission and distribution systems. The Utility Registrants anticipate
that they will fund their capital expenditures with a combination of internally generated funds and borrowings and additional capital contributions from parent.

Retirement Benefits

Management considers various factors when making pension funding decisions, including actuarially determined minimum contribution requirements under ERISA, contributions required to avoid benefit
restrictions and at-risk status as defined by the Pension Protection Act of 2006 (the Act), management of the pension obligation, and regulatory implications. The Act requires the attainment of certain
funding  levels  to  avoid  benefit  restrictions  (such  as  an  inability  to  pay  lump  sums  or  to  accrue  benefits  prospectively),  and  at-risk  status  (which  triggers  higher  minimum  contribution  requirements  and
participant  notification).  The  projected  contributions  below  reflect  a  funding  strategy  to  make  annual  contributions  with  the  objective  of  achieving  100%  funded  status  on  an ABO  basis  over  time.  This
funding strategy helps minimize volatility of future period required pension contributions. Exelon’s estimated annual qualified pension contributions will be $93 million in 2024. Unlike the qualified pension
plans, Exelon’s non-qualified pension plans are not funded, given they are not subject to statutory minimum contribution requirements.

While OPEB plans are also not subject to statutory minimum contribution requirements, Exelon does fund certain of its plans. For Exelon's funded OPEB plans, contributions generally equal accounting
costs, however, Exelon’s management has historically considered several factors in determining the level of contributions to its OPEB plans, including liabilities management, levels of benefit claims paid,
and regulatory implications (amounts deemed prudent to meet regulatory expectations and best assure continued rate recovery). The amounts below include benefit payments related to unfunded plans.

83

Table of Contents

The following table provides all Registrants' planned contributions to the qualified pension plans, planned benefit payments to non-qualified pension plans, and planned contributions to OPEB plans in 2024:

To  the  extent  interest  rates  decline  significantly  or  the  pension  and  OPEB  plans  earn  less  than  the  expected  asset  returns,  annual  pension  contribution  requirements  in  future  years  could  increase.
Conversely, to the extent interest rates increase significantly or the pension and OPEB plans earn greater than the expected asset returns, annual pension and OPEB contribution requirements in future
years could decrease. Additionally, expected contributions could change if Exelon changes its pension or OPEB funding strategy.

See Note 14 — Retirement Benefits of the Combined Notes to Consolidated Financial Statements for additional information on pension and OPEB contributions.

(a) As of December 31, 2022, Exelon's Long-term debt and Common equity capital structure percentages were 57% and 38%, respectively. The change in capital structure percentages above is a result of a decrease in

(b)

common equity due to the separation of Constellation in addition to an increase in long-term debt issuances. See Note 2 — Discontinued Operations for additional information regarding the separation.
Includes approximately $390 million, $205 million, and $184 million owed to unconsolidated affiliates of Exelon, ComEd, and PECO respectively. These special purpose entities were created for the sole purposes of
issuing mandatory redeemable trust preferred securities of ComEd and PECO.

Security Ratings

The  Registrants’  access  to  the  capital  markets,  including  the  commercial  paper  market,  and  their  respective  financing  costs  in  those  markets,  may  depend  on  the  securities  ratings  of  the  entity  that  is
accessing the capital markets.

The Registrants’ borrowings are not subject to default or prepayment as a result of a downgrading of securities, although such a downgrading of a Registrant’s securities could increase fees and interest
charges under that Registrant’s credit agreements.

As part of the normal course of business, the Registrants enter into contracts that contain express provisions or otherwise permit the Registrants and their counterparties to demand adequate assurance of
future  performance  when  there  are  reasonable  grounds  for  doing  so.  In  accordance  with  the  contracts  and  applicable  contracts  law,  if  the  Registrants  are  downgraded  by  a  credit  rating  agency,  it  is
possible  that  a  counterparty  would  attempt  to  rely  on  such  a  downgrade  as  a  basis  for  making  a  demand  for  adequate  assurance  of  future  performance,  which  could  include  the  posting  of  additional
collateral. See Note 15 — Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for additional information on collateral provisions.

The credit ratings for Exelon Corporate, PECO, BGE, PHI, Pepco, DPL, and ACE did not change for the year ended December 31, 2023. On July 26, 2023, S&P raised ComEd's long-term issuer credit
rating from 'BBB+' to a 'A-'. S&P also affirmed the current 'A' rating on ComEd's senior secured debt and 'A-2' short-term rating, which influences long and short-term borrowing cost. On December 20,
2023, Moody's revised its outlook on ComEd to negative from stable due to the final order issued by the ICC on December 14, 2023 rejecting ComEd's proposed Grid Plan and establishing retail rates for
2024-2027 as further discussed in Note 3 — Regulatory Matters. At the same time, Moody's affirmed ComEd's current 'A1' senior secured debt rating and its 'P-2' short-term rating.

Exelon, ComEd and Pepco have a currently effective combined shelf registration statement that expires in 2025. PECO and BGE plan to file a new combined shelf registration in the first quarter of 2024.
DPL and ACE periodically issue securities through the private placement markets. The ability of each Registrant to sell securities off the shelf registration statement or to access the private placement
markets will depend on a number of factors at the time of the proposed sale, including other required regulatory approvals, as applicable, the current financial condition of the Registrant, its securities
ratings and market conditions.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Registrants hold commodity and financial instruments that are exposed to the following market risks:

•

•

•

•

•

Commodity price risk, which is discussed further below.

Counterparty credit risk associated with non-performance by counterparties on executed derivative instruments and participation in all, or some of the established, wholesale spot energy markets
that are administered by PJM. The credit policies of PJM may, under certain circumstances, require that losses arising from the default of one member on spot energy market transactions be
shared by the remaining participants. See Note 15 — Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for a detailed discussion of counterparty credit
risk related to derivative instruments.

Equity price and interest rate risk associated with Exelon’s pension and OPEB plan trusts. See Note 14 — Retirement Benefits of the Combined Notes to Consolidated Financial Statements for
additional information.

Interest rate risk associated with changes in interest rates for the Registrants’ outstanding long-term debt. This risk is significantly reduced as substantially all of the Registrants’ outstanding debt
has fixed interest rates. There is inherent interest rate risk related to refinancing maturing debt by issuing new long-term debt. The Registrants use a combination of fixed-rate and variable-rate
debt to manage interest rate exposure. See Note 16 — Debt and Credit Agreements of the Combined Notes to Consolidated Financial Statements for additional information. In addition, Exelon
Corporate may utilize interest rate derivatives to lock in rate levels in anticipation of future financings, which are typically designated as cash flow hedges, or to lock in rate levels on borrowings,
which are typically designated as economic hedges. See Note 15 — Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for additional information.

Electric operating revenues risk associated with ComEd's distribution formula rate. ComEd's ROE for its electric distribution service through 2023 was directly correlated to yields on U.S. Treasury
bonds.  Exelon  Corporate  utilized  interest  rate  derivatives  to  mitigate  volatility  and  manage  risk  to  Exelon,  which  were  typically  accounted  for  as  economic  hedges.  See  Note  15  —  Derivative
Financial Instruments of the Combined Notes to Consolidated Financial Statements for additional information. Beginning January 1, 2024 ComEd's ROE for its electric distribution service will use a
fixed rate and no longer be exposed to volatility in yields on U.S. Treasury bonds. See Note 3 — Regulatory Matters for additional information.

The Utility Registrants operate primarily under cost-based rate regulation limiting exposure to the effects of market risk. Hedging programs are utilized to reduce exposure to energy and natural gas price
volatility and have no direct earnings impacts as the costs are fully recovered through regulatory-approved recovery mechanisms.

Exelon manages these risks through risk management policies and objectives for risk assessment, control and valuation, counterparty credit approval, and the monitoring and reporting of risk exposures.
Risk management issues are reported to Exelon’s Board of Directors, Exelon's Audit and Risk Committee, and/or the applicable Utility Board Registrant. The Registrants do not execute derivatives for
speculative or proprietary trading purposes.

91

Table of Contents

Commodity Price Risk (All Registrants)

Commodity  price  risk  is  associated  with  price  movements  resulting  from  changes  in  supply  and  demand,  fuel  costs,  market  liquidity,  weather  conditions,  governmental  regulatory  and  environmental
policies, and other factors. To the extent the total amount of energy Exelon purchases differs from the amount of energy it has contracted to sell, Exelon is exposed to market fluctuations in commodity
prices. Exelon seeks to mitigate its commodity price risk through the sale and purchase of electricity and natural gas.

ComEd entered into 20-year floating-to-fixed renewable energy swap contracts beginning in June 2012, which are considered an economic hedge and have changes in fair value recorded to an offsetting
regulatory asset or liability. ComEd has block energy contracts to procure electric supply that are executed through a competitive procurement process, which are considered derivatives and qualify for
NPNS,  and  as  a  result  are  accounted  for  on  an  accrual  basis  of  accounting.  PECO,  BGE,  Pepco,  DPL,  and ACE  have  contracts  to  procure  electric  supply  that  are  executed  through  a  competitive
procurement process. BGE, Pepco, DPL, and ACE have certain full requirements contracts, which are considered derivatives and qualify for NPNS, and as a result are accounted for on an accrual basis of
accounting. Other full requirements contracts are not derivatives.

PECO, BGE, and DPL also have executed derivative natural gas contracts, which qualify for NPNS, to hedge their long-term price risk in the natural gas market.

For additional information on these contracts, see Note 3 — Regulatory Matters and Note 15 — Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements.

The following table presents maturity and source of fair value for Exelon's and ComEd's mark-to-market commodity contract liabilities. The table provides two fundamental pieces of information. First, the
table provides the source of fair value used in determining the carrying amount of Exelon's and ComEd's total mark-to-market liabilities. Second, the table shows the maturity, by year, of Exelon's and
ComEd's  commodity  contract  liabilities  giving  an  indication  of  when  these  mark-to-market  amounts  will  settle  and  require  cash.  See  Note  17  —  Fair  Value  of  Financial Assets  and  Liabilities  of  the

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Management’s Report on Internal Control Over Financial Reporting

The management of Exelon Corporation (Exelon) is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f).
Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes
in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Exelon’s  management  conducted  an  assessment  of  the  effectiveness  of  Exelon’s  internal  control  over  financial  reporting  as  of  December  31,  2023.  In  making  this  assessment,  management  used  the
criteria in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, Exelon’s management concluded
that, as of December 31, 2023, Exelon’s internal control over financial reporting was effective.

The effectiveness of Exelon’s internal control over financial reporting as of December 31, 2023, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as
stated in their report which appears herein.

The management of PECO Energy Company (PECO) is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-
15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PECO’s management conducted an assessment of the effectiveness of PECO’s internal control over financial reporting as of December 31, 2023. In making this assessment, management used the criteria
in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, PECO’s management concluded that, as
of December 31, 2023, PECO’s internal control over financial reporting was effective.

Opinions on the Financial Statements and Internal Control over Financial Reporting

Report of Independent Registered Public Accounting Firm

We have audited the consolidated financial statements, including the related notes, of Exelon Corporation and its subsidiaries (the “Company”) as listed in the index appearing under Item 15(a)(1)(i), and
the financial statement schedules listed in the index appearing under Item 15(a)(1)(ii), (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal
control  over  financial  reporting  as  of  December  31,  2023,  based  on  criteria  established  in  Internal  Control  -  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the
Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its
operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our
opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of  December  31,  2023,  based  on  criteria  established  in  Internal  Control  -  Integrated
Framework (2013) issued by the COSO.

Basis for Opinions

The  Company's  management  is  responsible  for  these  consolidated  financial  statements,  for  maintaining  effective  internal  control  over  financial  reporting,  and  for  its  assessment  of  the  effectiveness  of
internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 8. Our responsibility is to express opinions on the Company’s
consolidated  financial  statements  and  on  the  Company's  internal  control  over  financial  reporting  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company Accounting
Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of
the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated
financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our
audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our
audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating
the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We
believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external  purposes  in  accordance  with  generally  accepted  accounting  principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures  that  (i)  pertain  to  the
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the  company;  (ii)  provide  reasonable  assurance  that  transactions  are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in
accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition
of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit
committee  and  that  (i)  relates  to  accounts  or  disclosures  that  are  material  to  the  consolidated  financial  statements  and  (ii)  involved  our  especially  challenging,  subjective,  or  complex  judgments.  The
communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below,
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Accounting for the Effects of Rate Regulation

As described in Notes 1 and 3 to the consolidated financial statements, the Company applies the authoritative guidance for accounting for certain types of regulation, which requires management to record
in the consolidated financial statements the effects of cost-based rate regulation for entities with regulated operations that meet the following criteria, (i) rates are established or approved by a third-party
regulator; (ii) rates are designed to recover the entity’s cost of providing services or products; and (iii) there is a reasonable expectation that rates designed to recover costs can be charged to and collected
from customers. The Company accounts for its regulated operations in accordance with regulatory and legislative guidance from the regulatory authorities having jurisdiction under state public utility laws
and the FERC under various Federal laws. Upon updates in material regulatory and legislative proceedings, where applicable, management will record new regulatory assets or liabilities and will assess
whether it is probable that its currently recorded regulatory assets and liabilities will be recovered and settled, respectively, in future rates. As of December 31, 2023, there were $10.9 billion of regulatory
assets and $10.0 billion of regulatory liabilities.

The principal considerations for our determination that performing procedures relating to the Company’s accounting for the effects of rate regulation is a critical audit matter are the high degree of audit
effort  to  assess  the  impact  of  regulation  on  accounting  for  regulatory  assets  and  liabilities  and  to  evaluate  the  complex  audit  evidence  related  to  whether  the  regulatory  assets  and  liabilities  will  be
recovered and settled.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included
testing  the  effectiveness  of  controls  relating  to  accounting  for  regulatory  matters  and  evaluation  of  new  and  existing  regulatory  assets  and  liabilities.  These  procedures  also  included,  among  others,
obtaining the Company’s correspondence with regulators, evaluating the reasonableness of management’s interpretation of regulatory guidance and proceedings and the related accounting implications,
and recalculating regulatory assets and liabilities based on provisions outlined in rate orders and other correspondence with regulators.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an
audit  of  its  internal  control  over  financial  reporting. As  part  of  our  audits  we  are  required  to  obtain  an  understanding  of  internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an
opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to
those  risks.  Such  procedures  included  examining,  on  a  test  basis,  evidence  regarding  the  amounts  and  disclosures  in  the  consolidated  financial  statements.  Our  audits  also  included  evaluating  the
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a
reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit
committee  and  that  (i)  relates  to  accounts  or  disclosures  that  are  material  to  the  consolidated  financial  statements  and  (ii)  involved  our  especially  challenging,  subjective,  or  complex  judgments.  The
communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below,
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Accounting for the Effects of Rate Regulation

As described in Notes 1 and 3 to the consolidated financial statements, the Company applies the authoritative guidance for accounting for certain types of regulation, which requires management to record
in the consolidated financial statements the effects of cost-based rate regulation for entities with regulated operations that meet the following criteria, (i) rates are established or approved by a third-party
regulator; (ii) rates are designed to recover the entity’s cost of providing services or products; and (iii) there is a reasonable expectation that rates designed to recover costs can be charged to and collected
from customers. The Company accounts for its regulated operations in accordance with regulatory and legislative guidance from the regulatory authorities having jurisdiction under state public utility laws
and the FERC under various Federal laws. Upon updates in material regulatory and legislative proceedings, where applicable, management will record new regulatory assets or liabilities and will assess
whether it is probable that its currently recorded regulatory assets and liabilities will be

109

Table of Contents

recovered and settled, respectively, in future rates. As of December 31, 2023, there were $1.9 billion of regulatory assets and $1.0 billion of regulatory liabilities.

The principal considerations for our determination that performing procedures relating to the Company’s accounting for the effects of rate regulation is a critical audit matter are the high degree of audit
effort  to  assess  the  impact  of  regulation  on  accounting  for  regulatory  assets  and  liabilities  and  to  evaluate  the  complex  audit  evidence  related  to  whether  the  regulatory  assets  and  liabilities  will  be
recovered and settled.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included
testing  the  effectiveness  of  controls  relating  to  accounting  for  regulatory  matters  and  evaluation  of  new  and  existing  regulatory  assets  and  liabilities.  These  procedures  also  included,  among  others,
obtaining the Company’s correspondence with regulators, evaluating the reasonableness of management’s interpretation of regulatory guidance and proceedings and the related accounting implications,
and recalculating regulatory assets and liabilities based on provisions outlined in rate orders and other correspondence with regulators.

This is a combined annual report of all Registrants. The Notes to the Consolidated Financial Statements apply to the Registrants as indicated parenthetically next to each corresponding disclosure. When
appropriate,  the  Registrants  are  named  specifically  for  their  related  activities  and  disclosures.  Each  of  the  Registrant’s  Consolidated  Financial  Statements  includes  the  accounts  of  its  subsidiaries. All
intercompany transactions have been eliminated, except for the historical transactions between the Utility Registrants and Generation for the purposes of presenting discontinued operations in all periods
presented in the Consolidated Statements of Operations and Comprehensive Income.

Through its business services subsidiary, BSC, Exelon provides its subsidiaries with a variety of support services at cost, including legal, human resources, financial, information technology, and supply
management services. PHI also has a business services subsidiary, PHISCO, which provides a variety of support services at cost, including legal, finance, engineering, customer operations, transmission
and distribution planning, asset management, system operations, and power procurement, to PHI operating Registrants. The costs of BSC and PHISCO are directly charged or allocated to the applicable
subsidiaries. The results of Exelon’s corporate operations are presented as “Other” within the consolidated financial statements and include intercompany eliminations unless otherwise disclosed.

As of December 31, 2023 and 2022, Exelon owned 100% of PECO, BGE, and PHI and more than 99% of ComEd. PHI owns 100% of Pepco, DPL, and ACE. As of December 31, 2021, Exelon owned
100% of Generation. As of February 1, 2022, as a result of the completion of the separation, Exelon no longer owns any interest in Generation. The separation of Constellation, including Generation and its
subsidiaries, meets the

criteria for discontinued operations and as such, its results of operations are presented as discontinued operations and have been excluded from continuing operations for all periods presented. Accounting
rules require that certain BSC costs previously allocated to Generation be presented as part of Exelon’s continuing operations as these costs do not qualify as expenses of the discontinued operations.
Comprehensive income, shareholders' equity, and cash flows related to Generation have not been segregated and are included in the Consolidated Statements of Operations and Comprehensive Income,
Consolidated Statements of Changes in Shareholders’ Equity, and Consolidated Statements of Cash Flows, respectively, for the periods ended December 31, 2022 and December 31, 2021. See Note 2 —
Discontinued Operations for additional information.

The accompanying consolidated financial statements have been prepared in accordance with GAAP for annual financial statements and in accordance with the instructions to Form 10-K and Regulation S-
X promulgated by the SEC.

COVID-19 (All Registrants)

The  Registrants  have  taken  steps  to  mitigate  the  potential  risks  posed  by  the  global  outbreak  (pandemic)  of  the  2019  novel  coronavirus  (COVID-19).  The  Registrants  provide  a  critical  service  to  their
customers and have taken measures to keep employees who operate the business safe and minimize unnecessary risk of exposure to the virus, including extra precautions for employees who work in the
field. The Registrants have implemented work from home policies where appropriate.

Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and
accompanying notes, and the amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. As of December 31, 2023 and 2022, and
through the date of this report, management assessed certain accounting matters that require consideration of forecasted financial information, including, but not limited to, allowance for credit losses and
the carrying value of goodwill and other long-lived assets, in context with the information reasonably available and the unknown future impacts of COVID-19. The Registrants' future assessment of the
magnitude and duration of COVID-19, as well as other factors, could result in material impacts to their consolidated financial statements in future reporting periods.

Use of Estimates (All Registrants)

The  preparation  of  financial  statements  of  each  of  the  Registrants  in  conformity  with  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  the  financial
statements and accompanying notes. Areas in which significant estimates have been made include, but are not limited to, the accounting for pension and OPEB, unbilled energy revenues, allowance for
credit losses, inventory reserves, goodwill and long-lived asset impairment assessments, derivative instruments, unamortized energy contracts, fixed asset depreciation, environmental costs and other loss
contingencies, AROs, and taxes. Actual results could differ from those estimates.

Regulatory Accounting (All Registrants)

For their regulated electric and gas operations, the Registrants reflect the effects of cost-based rate regulation in their financial statements, which is required for entities with regulated operations that meet
the following criteria: (1) rates are established or approved by a third-party regulator; (2) rates are designed to recover the entities’ cost of providing services or products; and (3) there is a reasonable
expectation  that  rates  designed  to  recover  costs  can  be  charged  to  and  collected  from  customers.  The  Registrants  account  for  their  regulated  operations  in  accordance  with  regulatory  and  legislative
guidance from the regulatory authorities having jurisdiction, principally the ICC, PAPUC, MDPSC, DCPSC, DEPSC, and NJBPU, under state public utility laws and the FERC under various Federal laws.
Regulatory assets and liabilities are amortized and the related expense or revenue is recognized in the Consolidated Statements of Operations consistent with the recovery or refund included in customer
rates. The Registrants' regulatory assets and liabilities as of the balance sheet date are probable of being recovered or settled in future rates. If a separable portion of the Registrants' business was no
longer able to meet the criteria discussed above, the affected entities would be required to eliminate from their consolidated financial statements the effects of regulation for that portion, which could have a
material impact on their financial statements. See Note 3 — Regulatory Matters for additional information.

With the exception of income tax-related regulatory assets and liabilities, the Registrants classify regulatory assets and liabilities with a recovery or settlement period greater than one year as both current
and noncurrent in

158

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 1 — Significant Accounting Policies

their Consolidated Balance Sheets, with the current portion representing the amount expected to be recovered from or refunded to customers over the next twelve-month period as of the balance sheet
date. Income tax-related regulatory assets and liabilities are classified entirely as noncurrent in the Registrants’ Consolidated Balance Sheets to align with the classification of the related deferred income
tax balances.

The Registrants treat the impacts of a final rate order received after the balance sheet date but prior to the issuance of the financial statements as a non-recognized subsequent event, as the receipt of a
final rate order is a separate and distinct event that has future impacts on the parties affected by the order.

Revenues (All Registrants)

Operating Revenues. The Registrants’ operating revenues generally consist of revenues from contracts with customers involving the sale and delivery of power and natural gas and utility revenues from
ARP. The Registrants recognize revenue from contracts with customers to depict the transfer of goods or services to customers in an amount that the entities expect to be entitled to in exchange for those
goods  or  services.  The  primary  sources  of  revenue  include  regulated  electric  and  natural  gas  tariff  sales,  distribution,  and  transmission  services. At  the  end  of  each  month,  the  Registrants  accrue  an
estimate for the unbilled amount of energy delivered or services provided to customers.

ComEd records ARP revenue for its best estimate of the electric distribution, energy efficiency, and transmission revenue impacts resulting from future changes in rates that ComEd believes are probable
of  approval  by  the  ICC  and  FERC  in  accordance  with  its  formula  rate  mechanisms.  BGE,  Pepco,  DPL,  and ACE  record ARP  revenue  for  their  best  estimate  of  the  electric  and  natural  gas  distribution
revenue impacts resulting from future changes in rates that they believe are probable of approval by the MDPSC, DCPSC, and/or NJBPU in accordance with their revenue decoupling mechanisms. PECO,
BGE, Pepco, DPL, and ACE record ARP revenue for their best estimate of the transmission revenue impacts resulting from future changes in rates that they believe are probable of approval by FERC in
accordance with their formula rate mechanisms. The Registrants recognize all ARP revenues that will be collected within 24 months of the end of the annual period in which they are recorded. See Note 3
— Regulatory Matters for additional information.

Taxes  Directly  Imposed  on  Revenue-Producing  Transactions. The Registrants collect certain taxes from customers such as sales and gross receipts taxes, along with other taxes, surcharges, and
fees, that are levied by state or local governments on the sale or distribution of electricity and gas. Some of these taxes are imposed on the customer, but paid by the Registrants, while others are imposed
on  the  Registrants.  Where  these  taxes  are  imposed  on  the  customer,  such  as  sales  taxes,  they  are  reported  on  a  net  basis  with  no  impact  to  the  Consolidated  Statements  of  Operations  and
Comprehensive Income. However, where these taxes are imposed on the Registrants, such as gross receipts taxes or other surcharges or fees, they are reported on a gross basis. Accordingly, revenues
are recognized for the taxes collected from customers along with an offsetting expense. See Note 22 — Supplemental Financial Information for taxes that are presented on a gross basis.

Leases (All Registrants)

The Registrants recognize a ROU asset and lease liability for operating and finance leases with a term of greater than one year. Operating lease ROU assets are included in Other deferred debits and
other  assets  and  operating  lease  liabilities  are  included  in  Other  current  liabilities  and  Other  deferred  credits  and  other  liabilities  on  the  Consolidated  Balance  Sheets.  Finance  lease  ROU  assets  are
included in Plant, property, and equipment, net and finance lease liabilities are included in Long-term debt due within one year and Long-term debt on the Consolidated Balance Sheets. The ROU asset is
measured  as  the  sum  of  (1)  the  present  value  of  all  remaining  fixed  and  in-substance  fixed  payments  using  the  rate  implicit  in  the  lease  whenever  that  is  readily  determinable  or  each  Registrant’s
incremental borrowing rate, (2) any lease payments made at or before the commencement date (less any lease incentives received), and (3) any initial direct costs incurred. The lease liability is measured
the  same  as  the  ROU  asset,  but  excludes  any  payments  made  before  the  commencement  date  and  initial  direct  costs  incurred.  Lease  terms  include  options  to  extend  or  terminate  the  lease  if  it  is
reasonably certain they will be exercised. The Registrants include non-lease components, which are service-related costs that are not integral to the use of the asset, in the measurement of the ROU asset
and lease liability.

Expense for operating leases and leases with a term of one year or less is recognized on a straight-line basis over the term of the lease, unless another systematic and rational basis is more representative
of the derivation of benefit from use of the leased property. Variable lease payments are recognized in the period in which the

159

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 1 — Significant Accounting Policies

related obligation is incurred. Operating lease expense, finance lease expense, and variable lease payments are primarily recorded to Operating and maintenance expense on the Registrants’ Statements
of Operations and Comprehensive Income.

Income from operating leases, including subleases, is recognized on a straight-line basis over the term of the lease, unless another systematic and rational basis is more representative of the pattern in
which income is earned over the term of the lease. Variable lease income is recognized in the period in which the related obligation is performed. Operating lease income and variable lease income are
recorded to Operating revenues on the Registrants’ Statements of Operations and Comprehensive Income.

The Registrants’ operating and finance leases consist primarily of real estate including office buildings and vehicles and equipment. The Registrants account for land right arrangements that provide for
exclusive use as leases while shared use land arrangements are generally not leases. The Registrants do not account for secondary use pole attachments as leases.

See Note 10 — Leases for additional information.

Income Taxes (All Registrants)

Deferred  federal  and  state  income  taxes  are  recorded  on  significant  temporary  differences  between  the  book  and  tax  basis  of  assets  and  liabilities  and  for  tax  benefits  carried  forward.  Investment  tax
credits  have  been  deferred  in  the  Registrants’  Consolidated  Balance  Sheets  and  are  recognized  in  book  income  over  the  life  of  the  related  property.  The  Registrants  account  for  uncertain  income  tax
positions using a benefit recognition model with a two-step approach; a more-likely-than-not recognition criterion; and a measurement approach that measures the position as the largest amount of tax
benefit that is greater than 50% likely of being realized upon ultimate settlement. If it is not more-likely-than-not that the benefit of the tax position will be sustained on its technical merits, no benefit is
recorded. Uncertain tax positions that relate only to timing of when an item is included on a tax return are considered to have met the recognition threshold. The Registrants recognize accrued interest
related to unrecognized tax benefits in Interest expense, net or Other, net (interest income) and recognize penalties related to unrecognized tax benefits in Other, net in their Consolidated Statements of
Operations and Comprehensive Income.

Cash and Cash Equivalents (All Registrants)

The Registrants consider investments purchased with an original maturity of three months or less to be cash equivalents.

Restricted Cash and Cash Equivalents (All Registrants)

Restricted cash and cash equivalents represent funds that are restricted to satisfy designated current liabilities. As of December 31, 2023 and 2022, the Registrants' restricted cash and cash equivalents
primarily represented the following items:

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 1 — Significant Accounting Policies

Restricted cash and cash equivalents not available to satisfy current liabilities are classified as noncurrent assets. As of December 31, 2023 and 2022, the Registrants' noncurrent restricted cash and cash
equivalents primarily represented ComEd’s over-recovered RPS costs and alternative compliance payments received from RES pursuant to FEJA and costs for the remediation of an MGP site.

See Note 16 — Debt and Credit Agreements and Note 22 — Supplemental Financial Information for additional information.

Allowance for Credit Losses on Accounts Receivables (All Registrants)

The allowance for credit losses reflects the Registrants’ best estimates of losses on the customers' accounts receivable balances based on historical experience, current information, and reasonable and
supportable forecasts.

The allowance for credit losses is developed by applying loss rates for each Utility Registrant, based on historical loss experience, current conditions, and forward-looking risk factors, to the outstanding
receivable balance by customer risk segment. Utility Registrants' customer accounts are written off consistent with approved regulatory requirements. Adjustments to the allowance for credit losses are
primarily recorded to Operating and maintenance expense on the Registrants' Consolidated Statements of Operations and Comprehensive Income or Regulatory assets and liabilities on the Registrants'
Consolidated Balance Sheets. See Note 3 - Regulatory Matters for additional information regarding the regulatory recovery of credit losses on customer accounts receivable.

The Registrants have certain non-customer receivables in Other deferred debits and other assets which primarily are with governmental agencies and other high-quality counterparties with no history of
default. As such, the allowance for credit losses related to these receivables is not material.  The Registrants monitor these balances and will record an allowance if there are indicators of a decline in
credit quality. See Note 6 — Accounts Receivable for additional information.

Inventories (All Registrants)

Inventory is recorded at the lower of weighted average cost or net realizable value. Provisions are recorded for excess and obsolete inventory. Fossil fuel and Materials and supplies are generally included
in inventory when purchased. Fossil fuel is expensed to Purchased power and fuel expense when used or sold. Materials and supplies generally includes transmission and distribution materials and are
expensed to Operating and maintenance or capitalized to Property, plant, and equipment, as appropriate, when installed or used.

Property, Plant, and Equipment (All Registrants)

Property, plant, and equipment is recorded at original cost. Original cost includes construction-related direct labor and material costs and indirect construction costs including labor and related costs of
departments associated with supporting construction activities. When appropriate, original cost also includes AFUDC for regulated property at the Utility Registrants. The cost of repairs and maintenance
and minor replacements of property is charged to Operating and maintenance expense as incurred.

Third parties reimburse the Utility Registrants for all or a portion of expenditures for certain capital projects. Such contributions in aid of construction costs (CIAC) are recorded as a reduction to Property,
plant, and equipment, net.

Upon retirement, the cost of property, net of salvage, is charged to accumulated depreciation consistent with the composite and group methods of depreciation. Depreciation expense at ComEd, BGE,
Pepco,  DPL,  and ACE  includes  the  estimated  cost  of  dismantling  and  removing  plant  from  service  upon  retirement. Actual  incurred  removal  costs  are  applied  against  a  related  regulatory  liability  or
recorded to a regulatory asset if in excess of previously collected removal costs. PECO’s removal costs are capitalized to accumulated depreciation when incurred and recorded to depreciation expense
over the life of the new asset constructed consistent with PECO’s regulatory recovery method.

Capitalized Software. Certain costs, such as design, coding, and testing incurred during the application development stage of software projects that are internally developed or purchased for operational
use are capitalized within Property, plant, and equipment. Similar costs incurred for cloud-based solutions treated as

161

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 1 — Significant Accounting Policies

service arrangements are capitalized within Other Current Assets and Deferred Debits and Other Assets. Such capitalized amounts are amortized ratably over the expected lives of the projects when they
become  operational,  generally  not  to  exceed  five  years.  Certain  other  capitalized  software  costs  are  being  amortized  over  longer  lives  based  on  the  expected  life  or  pursuant  to  prescribed  regulatory
requirements.

AFUDC. AFUDC is the cost, during the period of construction, of debt and equity funds used to finance construction projects for regulated operations. AFUDC is recorded to construction work in progress
and as a non-cash credit to an allowance that is included in interest expense for debt-related funds and other income and deductions for equity-related funds. The rates used for capitalizing AFUDC are
computed under a method prescribed by regulatory authorities.

See Note 7 — Property, Plant, and Equipment, Note 8 — Jointly Owned Electric Utility Plant and Note 22 — Supplemental Financial Information for additional information.

Depreciation and Amortization (All Registrants)

Depreciation is generally recorded over the estimated service lives of property, plant, and equipment on a straight-line basis using the group or composite methods of depreciation. The group approach is
typically for groups of similar assets that have approximately the same useful lives and the composite approach is used for dissimilar assets that have different lives. Under both methods, a reporting entity
depreciates the assets over the average life of the assets in the group. ComEd, BGE, Pepco, DPL, and ACE's depreciation expense includes the estimated cost of dismantling and removing plant from
service upon retirement, which is consistent with each utility's regulatory recovery method. PECO's removal costs are capitalized to accumulated depreciation when incurred and recorded to depreciation
expense over the life of the new asset constructed consistent with PECO's regulatory recovery method. The estimated service lives for the Registrants are based on a combination of depreciation studies
and historical retirements. See Note 7 — Property, Plant, and Equipment for additional information regarding depreciation.

Amortization of regulatory assets and liabilities are recorded over the recovery or refund period specified in the related legislation or regulatory order or agreement. When the recovery or refund period is
less  than  one  year,  amortization  is  recorded  to  the  line  item  in  which  the  deferred  cost  or  income  would  have  originally  been  recorded  in  the  Registrants’  Consolidated  Statements  of  Operations  and
Comprehensive  Income. Amortization  of  ComEd’s  electric  distribution  and  energy  efficiency  formula  rate  regulatory  assets  and  the  Utility  Registrants'  transmission  formula  rate  regulatory  assets  is
recorded to Operating revenues.

Amortization of income tax related regulatory assets and liabilities is generally recorded to Income tax expense. Except for the regulatory assets and liabilities discussed above, amortization is generally
recorded to Depreciation and amortization in the Registrants’ Consolidated Statements of Operations and Comprehensive Income when the recovery period is more than one year.

See Note 3 — Regulatory Matters and Note 22 — Supplemental Financial Information for additional information regarding the amortization of the Registrants' regulatory assets.

Asset Retirement Obligations (All Registrants)

The Registrants estimate and recognize a liability for their legal obligation to perform asset retirement activities even though the timing and/or methods of settlement may be conditional on future events.
The Registrants update their AROs either annually or on a rotational basis at least once every three years, based on a risk profile, unless circumstances warrant more frequent updates. The updates factor
in new cost estimates, credit-adjusted, risk-free rates (CARFR) and escalation rates, and the timing of cash flows. AROs are accreted throughout each year to reflect the time value of money for these
present value obligations through an increase to Regulatory assets. See Note 9 — Asset Retirement Obligations for additional information.

Guarantees (All Registrants)

If  necessary,  the  Registrants  recognize  a  liability  at  the  time  of  issuance  of  a  guarantee  for  the  fair  value  of  the  obligations  they  have  undertaken  by  issuing  the  guarantee.  The  liability  is  reduced  or
eliminated as the Registrants are released from risk under the guarantee. Depending on the nature of the guarantee, the release from risk of the Registrant may be recognized only upon the expiration or
settlement of the guarantee or by a

162

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 1 — Significant Accounting Policies

systematic and rational amortization method over the term of the guarantee. See Note 18 — Commitments and Contingencies for additional information.

Asset Impairments

Long-Lived Assets (All Registrants). The Registrants evaluate the carrying value of long-lived assets for recoverability whenever events or changes in circumstances indicate that the carrying value of
those assets may not be recoverable. Indicators of impairment may include specific regulatory disallowance, abandonment, or plans to dispose of a long-lived asset significantly before the end of its useful
life.  When  the  estimated  undiscounted  future  cash  flows  attributable  to  the  long-lived  asset  may  not  be  recoverable,  the  amount  of  the  impairment  loss  is  determined  by  measuring  the  excess  of  the
carrying amount of the long-lived asset over its fair value.

Goodwill  (Exelon,  ComEd,  and  PHI). Goodwill represents the excess of the purchase price paid over the estimated fair value of the net assets acquired and liabilities assumed in the acquisition of a
business. Goodwill is not amortized but is assessed for impairment at least annually or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value
of a reporting unit below its carrying value. See Note 12 — Intangible Assets for additional information.

Derivative Financial Instruments (All Registrants)

Derivatives are recognized on the balance sheet at their fair value unless they qualify for certain exceptions, including NPNS. For derivatives that qualify and are designated as cash flow hedges, changes
in  fair  value  each  period  are  initially  recorded  in AOCI  and  recognized  in  earnings  when  the  underlying  hedged  transaction  affects  earnings. Amounts  recognized  in  earnings  are  recorded  in  Interest
expense,  net  on  the  Consolidated  Statement  of  Operations  and  Comprehensive  Income  based  on  the  activity  the  transaction  is  economically  hedging. Cash  inflows  and  outflows  related  to  derivative
instruments designated as cash flow hedges are included as a component of operating, investing, or financing cash flows in the Consolidated Statements of Cash Flows, depending on the nature of each
transaction.

For derivatives intended to serve as economic hedges, which are not designated for hedge accounting, changes in fair value each period are recognized in earnings or as a regulatory asset or liability
each  period.  Amounts  recognized  in  earnings  are  recorded  in  Electric  operating  revenues,  Purchased  power  and  fuel,  or  Interest  expense  in  the  Consolidated  Statements  of  Operations  and
Comprehensive Income based on the activity the transaction is economically hedging. Changes in fair value are also recorded as a regulatory asset or liability when there is an ability to recover or return
the associated costs or benefits in accordance with regulatory requirements. Cash inflows and outflows related to derivative instruments are included as a component of operating, investing, or financing
cash flows in the Consolidated Statements of Cash Flows, depending on the nature of the hedged item. See Note 3 — Regulatory Matters and Note 15 — Derivative Financial Instruments for additional
information.

Retirement Benefits (All Registrants)

Exelon sponsors defined benefit pension plans and OPEB plans.

The plan obligations and costs of providing benefits under these plans are measured as of December 31. The measurement involves various factors, assumptions, and accounting elections. The impact of
assumption changes or experience different from that assumed on pension and OPEB obligations is recognized over time rather than immediately recognized in the Consolidated Statements of Operations
and  Comprehensive  Income.  Gains  or  losses  in  excess  of  the  greater  of  ten  percent  of  the  projected  benefit  obligation  or  the  MRV  of  plan  assets  are  amortized  over  the  expected  average  remaining
service period of plan participants. See Note 14 — Retirement Benefits for additional information.

New Accounting Standards (All Registrants)

New Accounting Standards Issued and Not Yet Adopted as of December 31, 2023: The following new authoritative accounting guidance issued by the FASB has not yet been adopted and reflected
by the Registrants in their consolidated financial statements as of December 31, 2023. Unless otherwise indicated, the Registrants are currently assessing the impacts such guidance may have (which
could be material) in their Consolidated Balance Sheets, Consolidated Statements of Operations and Comprehensive Income, Consolidated Statements

of  Cash  Flows  and  disclosures,  as  well  as  the  potential  to  early  adopt  where  applicable.  The  Registrants  have  assessed  other  FASB  issuances  of  new  standards  which  are  not  listed  below  given  the
current expectation that such standards will not significantly impact the Registrants' financial reporting.

Segment  Reporting  (Issued  November  2023). Improves  reportable  segment  disclosure  requirements,  primarily  through  enhanced  disclosures  about  significant  segment  expenses.  The  objective  of  the
revised guidance is to introduce a new requirement to disclose significant segment expenses regularly provided to the CODM, extend certain annual disclosures to interim periods, clarify single reportable
segment entities must apply ASC 280 in its entirety, permit more than one measure of segment profit or loss to be reported under certain conditions, and require disclosure of the title and position of the
CODM. The standard is effective for annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025, with early adoption permitted. The standard will be applied retrospectively.

Improvement  to  Income  Tax  Disclosures  (Issued  December  2023).  Provides  additional  disclosure  requirements  related  to  the  effective  tax  rate  reconciliation  and  income  taxes  paid.  Under  the  revised
guidance for the effective tax reconciliations, entities would be required to disclose: (1) eight specific categories in the effective tax rate reconciliation in both percentages and reporting currency amount, (2)
additional information for reconciling items over a certain threshold, (3) explanation of individual reconciling items disclosed, and (4) provide a qualitative description of the state and local jurisdictions that
contribute to the majority of the state income tax expense. For each annual period presented, the new standard requires disclosure of the year-to-date amount of income taxes paid (net of refunds received)
disaggregated by federal, state, and foreign. It also requires additional disaggregated information on income taxes paid (net of refunds received) to an individual jurisdiction equal to or greater than 5% of
total income taxes paid (net of refunds received). The standard is effective January 1, 2025, with early adoption permitted.

2. Discontinued Operations (Exelon)

On February 21, 2021, Exelon's Board of Directors approved a plan to separate the Utility Registrants and Generation, creating two publicly traded companies ("the separation"). Exelon completed the
separation on February 1, 2022, through the distribution of 326,663,937 common stock shares of Constellation, the new publicly traded company, to Exelon shareholders. Under the separation plan, Exelon
shareholders retained their current shares of Exelon stock and received one share of Constellation common stock for every three shares of Exelon common stock held on January 20, 2022, the record date
for the distribution, in a transaction that was tax-free to Exelon and its shareholders for U.S. federal income tax purposes.

Constellation was newly formed and incorporated in Pennsylvania on June 15, 2021 for the purposes of separation and holds Generation (including Generation's subsidiaries).

Pursuant to the separation:

•

•

•

•

•

Exelon entered into four term loans consisting of a 364-day term loan for $1.15 billion and three 18-month term loans for $300 million, $300 million, and $250 million, respectively. Exelon issued
these term loans primarily to fund the cash payment to Constellation and for general corporate purposes. See Note 16 — Debt and Credit Agreements for additional information.

Exelon made a cash payment of $1.75 billion to Constellation on January 31, 2022.

Exelon contributed its equity ownership interest in Generation to Constellation. Exelon no longer retains any equity ownership interest in Generation or Constellation.

Exelon transferred certain corporate assets and employee-related obligations to Constellation.

Exelon received cash from Generation of $258 million to settle the intercompany loan on January 31, 2022. See Note 16 — Debt and Credit Agreements for additional information.

Continuing Involvement

In order to govern the ongoing relationships between Exelon and Constellation after the separation, and to facilitate an orderly transition, Exelon and Constellation have entered into several agreements,
including the following:

(Dollars in millions, except per share data unless otherwise noted)

Note 2 — Discontinued Operations

•

•

•

Separation Agreement – governs the rights and obligations between Exelon and Constellation regarding certain actions to be taken in connection with the separation, among others, including the
allocation of assets and liabilities between Exelon and Constellation.

Transition Services Agreement (TSA) – governs the terms and conditions of the services that Exelon provides to Constellation and Constellation provides to Exelon for an expected period of two
years, provided that certain services may be longer than the term and services may be extended with approval from both parties. The services include specified accounting, finance, information
technology, human resources, employee benefits, and other services that have historically been provided on a centralized basis by BSC. For the year ended December 31, 2023, the amounts
Exelon billed Constellation and Constellation billed Exelon for these services were $151 million recorded in Other income, net and $14 million recorded in Operating and maintenance expense,
respectively. For the period from February 1, 2022 to December 31, 2022, the amounts Exelon billed Constellation and Constellation billed Exelon for these services were $266 million recorded in
Other income, net and $43 million recorded in Operating and maintenance expense, respectively.

Tax Matters Agreement (TMA) – governs the respective rights, responsibilities and obligations of Exelon and Constellation with respect to all tax matters, including tax liabilities and benefits, tax
attributes, tax returns, tax contests and other tax sharing regarding U.S. federal, state, local and foreign income taxes, other tax matters and related tax returns. See Note 13 — Income Taxes for
additional information.

In addition, the Utility Registrants will continue to incur expenses from transactions with Constellation after the separation. Prior to the separation, such expenses were primarily recorded as Purchased
power from affiliates and an immaterial amount recorded as Operating and maintenance expense from affiliates at the Utility Registrants. After the separation, such expenses are primarily recorded as
Purchased power and an immaterial amount recorded as Operating and maintenance expense at the Utility Registrants.

ComEd had an ICC-approved RFP contract with Constellation to provide a portion of ComEd’s electric supply requirements. ComEd also purchased RECs and ZECs from Constellation.

PECO received electric supply from Constellation under contracts executed through PECO’s competitive procurement process. In addition, PECO had a ten-year agreement with Constellation to
sell solar AECs.

BGE received a portion of its energy requirements from Constellation under its MDPSC-approved market-based SOS and gas commodity programs.

Pepco received electric supply from Constellation under contracts executed through Pepco’s competitive procurement process approved by the MDPSC and DCPSC.

DPL received a portion of its energy requirements from Constellation under its MDPSC and DEPSC approved market-based SOS commodity programs.

ACE received electric supply from Constellation under contracts executed through ACE’s competitive procurement process approved by the NJBPU.

ComEd and PECO also have receivables with Constellation for estimated excess funds at the end of decommissioning the Regulatory Agreement Units, such amounts are due back to ComEd and PECO,
as applicable, for payment to their respective customers. See Note 3 — Regulatory Matters and Note 23 — Related Party Transactions for additional information.

Discontinued Operations

The separation represented a strategic shift that had a major effect on Exelon’s operations and financial results. Accordingly, the separation met the criteria for discontinued operations.

There were no results from discontinued operations for the year ended December 31, 2023. The following table presents the results of Constellation that have been reclassified from continuing operations
and included in discontinued operations within Exelon’s Consolidated Statements of Operations and Comprehensive Income for the years ended December 31, 2022 and 2021.

(Dollars in millions, except per share data unless otherwise noted)

Note 2 — Discontinued Operations

These results are primarily Generation, which is comprised of Exelon’s Mid-Atlantic, Midwest, New York, ERCOT, and Other Power Regions reportable segments, and include the impact of transaction
costs, certain BSC costs, including any transition costs, that were historically allocated and directly attributable to Generation, transactions between Generation and the Utility Registrants, and tax-related
adjustments. Transaction costs include costs for external bankers, accountants, appraisers, lawyers, external counsels and other advisors, among others, who are involved in the negotiation, appraisal, due
diligence and regulatory approval of the separation. Transition costs are primarily employee-related costs such as recruitment expenses, costs to establish certain stand-alone functions and information
technology systems, professional services fees, and other separation-related costs during the transition to separate Generation. For the purposes of reporting discontinued operations, these results also
include transactions between Generation and the Utility Registrants that were historically eliminated within Exelon’s Consolidated Statements of Operations, as these transactions will be ongoing after the
separation. Certain BSC costs that were historically allocated to Generation are presented as part of continuing operations in Exelon’s Consolidated Statements of Operations as these costs do not qualify
as expenses of the discontinued operations per the accounting rules.

__________
(a) ComEd’s 2023 approved revenue requirement above reflects an increase of $144 million for the initial year revenue requirement for 2023 and an increase of $55 million related to the annual reconciliation for 2021. The
revenue requirement for 2023 provides for a weighted average debt and equity return on distribution rate base of 5.94% inclusive of an allowed ROE of 7.85%, reflecting the monthly average yields for 30-year treasury
bonds plus 580 basis points. The reconciliation revenue requirement for 2021 provides for a weighted average debt and equity return on distribution rate base of 5.91%, inclusive of an allowed ROE of 7.78%, reflecting
the monthly yields on 30-year treasury bonds plus 580 basis points less a performance metrics penalty of 7 basis points. ComEd's last performance-based electric distribution formula rate update filing under EIMA was
completed in 2022. See discussion of CEJA below for details on the transition away from the electric distribution formula rate.

(b) Reflects a four-year cumulative multi-year rate plan for January 1, 2024 to December 31, 2027. On December 14, 2023, the ICC approved year-over-year distribution revenue requirement increases in 2024-2027, with
an amendatory order on January 10, 2024, of approximately $451 million effective January 1, 2024, $14 million effective January 1, 2025, $6 million effective January 1, 2026, and $30 million effective January 1, 2027,
based on an ROE of 8.905%, an equity ratio of 50%, and year end 2022 rate base. The ICC rejected ComEd’s Grid Plan, requiring ComEd to file a revised Grid Plan by March 13, 2024, 90 days after the issuance of the
December final order. The ICC also directed that the revised Grid Plan would be reviewed through further formal proceedings in that docket. On January 10, 2024, the ICC granted one portion of ComEd’s application for
rehearing of the December 14, 2023 final order, and directing that a 150-day rehearing process reconsider the revenue requirements for the test years (2024-2027), absent an approved Grid Plan. On January 31,2024,
the ICC further clarified the scope of the rehearing process. ComEd anticipates that the revenue requirements determined during the rehearing process will be further updated upon approval of a revised Grid Plan. On
January 10, 2024, ComEd also filed with the Illinois appellate court an appeal of various aspects of the ICC’s final order on which rehearing was denied, including the 8.905% ROE, 50% equity ratio, and denial of any
return on ComEd’s pension asset.

(Dollars in millions, except per share data unless otherwise noted)

Note 3 — Regulatory Matters

(c) On November 30, 2023, the Delivery Reconciliation Amount for 2022 defined in Rider Delivery Service Pricing Reconciliation (Rider DSPR) was approved. The delivery reconciliation amount allows for the reconciliation
of the revenue requirement in effect in the final years in which formula rates are determined and until such time as new rates are established under ComEd’s approved MRP. The 2023 filing reconciled the delivery
service rates in effect in 2022 with the actual delivery service costs incurred in 2022. The reconciliation revenue requirement provides for a weighted average debt and equity return on distribution rate base of 6.48%,
inclusive of an allowed ROE of 8.91%, reflecting the monthly yields on 30-year treasury bonds plus 580 basis points.

(d) The PECO electric and natural gas base rate case proceedings were resolved through settlement agreements, which did not specify an approved ROE.
(e) Reflects a three-year cumulative multi-year plan for 2021 through 2023. BGE proposed to use certain tax benefits to fully offset the increases in 2021 and 2022 and partially offset the increase in 2023. The MDPSC
awarded BGE electric revenue requirement increases of $59 million, $39 million, and $42 million, before offsets, in 2021, 2022, and 2023, respectively, and natural gas revenue requirement increases of $53 million,
$11 million, and $10 million, before offsets, in 2021, 2022, and 2023, respectively. However, the MDPSC utilized the tax benefits to fully offset the increases in 2021 and January 2022 such that customer rates remained
unchanged. For the remainder of 2022, the MDPSC chose to offset only 25% of the cumulative 2021 and 2022 electric revenue requirement increases and 50% of the cumulative gas revenue requirement increases. In
2021, the MDPSC deferred a decision on whether to use certain tax benefits to offset the revenue requirement increases in 2023 and directed BGE to make another proposal at the end of 2022. In September 2022,
BGE proposed that tax benefits not be used to offset the 2023 revenue requirement increases. On October 26, 2022, the MDPSC accepted BGE's recommendation to not use tax benefits to offset the 2023 revenue
requirement increases.

(f) Reflects a three-year cumulative multi-year plan for January 1, 2024 through December 31, 2026. The MDPSC awarded BGE electric revenue requirement increases of $41 million, $113 million, and $25 million in 2024,
2025, and 2026, respectively, and natural gas revenue requirement increases of $126 million, $62 million, and $41 million in 2024, 2025, and 2026, respectively. Requested revenue requirement increases will be used
to  recover  capital  investments  designed  to  increase  the  resilience  of  the  electric  and  gas  distribution  systems  and  support  Maryland's  climate  and  regulatory  initiatives.  The  MDPSC  also  approved  a  portion  of  the
requested  2021  and  2022  reconciliation  amounts,  which  will  be  recovered  through  separate  electric  and  gas  riders  starting  in  2024. As  such,  the  reconciliation  amounts  are  not  included  in  the  approved  revenue
requirement  increases.  The  2021  reconciliation  amounts  are  $13  million  and  $7  million  for  electric  and  gas,  respectively,  and  the  2022  reconciliation  amounts  are  $39  million  and  $15  million  for  electric  and  gas,
respectively.

(g) Reflects a three-year cumulative multi-year plan for April 1, 2021 through March 31, 2024. The MDPSC awarded Pepco electric incremental revenue requirement increases of $21 million, $16 million, and $15 million,
before offsets, for the 12-month periods ending March 31, 2022, 2023, and 2024, respectively. Pepco proposed to utilize certain tax benefits to fully offset the increase through 2023 and partially offset customer rate
increases in 2024. However, the MDPSC only utilized the acceleration of refunds for certain tax benefits to fully offset the increases such that customer rates remain unchanged through March 31, 2022. On February
23, 2022, the MDPSC chose to offset 25% of the cumulative revenue requirement increase through March 31, 2023. In 2021, the MDPSC deferred a decision on whether to use certain tax benefits to offset the revenue
requirement increases for the 12-month period ending March 31, 2024. In December 2022 Pepco proposed that tax benefits not be used to offset the revenue requirement increases for this period. On January 25,
2023, the MDPSC accepted Pepco’s recommendations not to use tax benefits to offset revenue requirement increases for the 12-month period ending March 31, 2024.

(h) Reflects a three-year cumulative multi-year plan for January 1, 2023 through December 31, 2025. The MDPSC awarded DPL electric incremental revenue requirement increases of $17 million, $6 million, and $6 million

for 2023, 2024, and 2025, respectively.

(i) Requested and approved increases are before New Jersey sales and use tax. The NJBPU awarded ACE electric revenue requirement increases of $36 million and $9 million effective December 1, 2023 and February 1,

2024, respectively.

(a) Reflects a three-year cumulative multi-year plan for January 1, 2024 through December 31, 2026 submitted to the DCPSC. Pepco requested total electric revenue requirement increases of $117 million, $37 million, and
$37 million in 2024, 2025 and 2026, respectively. Requested revenue requirement increases will be used to recover capital investments designed to advance system-readiness and support the District of Columbia’s
climate and clean energy goals.

(b) Reflects a three-year cumulative multi-year plan for April 1, 2024 through March 31, 2027 submitted to the MDPSC.  Pepco requested total electric revenue requirement increases of $69 million, $54 million and $51
million effective April 1, 2024, April 1, 2025, and April 1, 2026, respectively through its rebuttal filing made on January 26, 2024.  The plan contains a proposed nine-month extension period with a requested revenue
requirement increase of $14 million effective April 1, 2027 through December 31, 2027. Requested revenue requirement increases will be used to recover capital investments designed to advance system-readiness and
support Maryland's climate and clean energy goals. On August 7, 2023, the MDPSC issued an order approving a settlement agreement which allows Pepco to establish a revenue deferral mechanism to recover its full
Commission-authorized year 1 increase between July 1, 2024 through March 31, 2025 and extend the procedural schedule to address intervenor resource constraints.

(c) The rates went into effect on July 15, 2023, subject to refund.

Transmission Formula Rates

The Utility Registrants' transmission rates are each established based on a FERC-approved formula. ComEd, BGE, Pepco, DPL, and ACE are required to file an annual update to the FERC-approved
formula on or before May 15, and PECO is required to file on or before May 31, with the resulting rates effective on June 1 of the same year. The annual update for ComEd is based on prior year actual
costs and current year projected capital additions (initial year revenue requirement). The update for ComEd also reconciles any differences between the revenue requirement in effect beginning June 1 of
the prior year and actual costs incurred for that year (annual reconciliation). The annual update for PECO is based on prior year actual costs and current year projected capital additions, accumulated
depreciation, and accumulated deferred income taxes. The annual update for BGE, Pepco, DPL, and ACE is based on prior year actual costs and current year projected capital additions, accumulated
depreciation, Depreciation and amortization expense, and accumulated deferred income taxes. The update for PECO, BGE, Pepco, DPL, and ACE also reconciles any differences between the actual costs
and actual revenues for the calendar year (annual reconciliation).

designated load by BGE.

Other State Regulatory Matters

Illinois Regulatory Matters

CEJA  (Exelon  and  ComEd). On September 15, 2021, the Governor of Illinois signed into law CEJA. CEJA includes, among other features, (1) procurement of CMCs  from  qualifying  nuclear-powered
generating facilities, (2) a requirement to file a general rate case or a new four-year MRP no later than January 20, 2023 to establish rates effective after ComEd’s existing performance-based distribution
formula rate sunsets, (3) requirements that ComEd and the ICC initiate and conduct various regulatory proceedings on subjects including ethics, spending, grid investments, and performance metrics.

ComEd Electric Distribution Rates

ComEd filed, and received approval for, its last performance-based electric distribution formula rate update under EIMA in 2022; those rates were in effect throughout 2023.

On February 3, 2022, the ICC approved a tariff that establishes the process under which ComEd reconciled its 2022 and will reconcile its 2023 rate year revenue requirements with actual costs. Those
reconciliation amounts are determined using the same process used for prior reconciliations under the performance-based electric distribution formula rate. Using that process, for the rate years 2022 and
2023 ComEd will ultimately collect revenues from customers reflecting each year’s actual recoverable costs, year-end rate base, and a weighted average debt and equity return on distribution rate base,
with the ROE component based on the annual average of the monthly yields of the 30-year U.S. Treasury bonds plus 580 basis points. In April 2023, ComEd filed its first petition with the ICC to reconcile its
2022 actual costs with the approved revenue requirement that was in effect in 2022; the final order was issued on November 30, 2023, for rates beginning January 2024. In 2024, ComEd will file with the
ICC its 2023 actual costs with the approved revenue requirement that was in effect in 2023.

Note 3 — Regulatory Matters

Beginning in 2024, ComEd will recover from retail customers, subject to certain exceptions, the costs it incurs to provide electric delivery services either through its electric distribution rate or other recovery
mechanisms authorized by CEJA. On January 17, 2023, ComEd filed a petition with the ICC seeking approval of a MRP for 2024-2027. The MRP supports a multi-year grid plan (Grid Plan), also filed on
January 17, covering planned investments on the electric distribution system within ComEd’s service area through 2027. Costs incurred during each year of the MRP are subject to ICC review and the
plan’s revenue requirement for each year will be reconciled with the actual costs that the ICC determines are prudently and reasonably incurred for that year. The reconciliation is subject to adjustment for
certain costs, including a limitation on recovery of costs that are more than 105% of certain costs in the previously approved MRP revenue requirement, absent a modification of the rate plan itself. Thus,
for example, the rate adjustments necessary to reconcile 2024 revenues to ComEd’s actual 2024 costs incurred would take effect in January 2026 after the ICC’s review during 2025. On May 22, 2023,
direct testimony was filed by ICC staff and more than a dozen intervenors and intervenor groups. The testimonies addressed a wide variety of topics, including rate of return on equity, capital structure, grid
planning, various distribution grid and information technology investments, and affordability and customer service. ComEd also made voluntary adjustments and, per the ICC’s final beneficial electrification
order  requiring  ComEd  to  recover  beneficial  electrification  costs  through  the  MRP,  increased  its  total  revenue  requirement  request  from  $1.472  billion  to  $1.545  billion.  ComEd  filed  its  reply  brief  on
September 27, 2023, to adjust its total requested revenue requirement increase to $1.487 billion.

On December 14, 2023, the ICC issued a final order. The ICC rejected ComEd’s Grid Plan as non-compliant with certain requirements of CEJA, and required ComEd to file a revised Grid Plan by March
13, 2024, 90 days after the issuance of the final order. In the absence of an approved Grid Plan, the ICC set ComEd’s forecast revenue requirements for 2024-2027 based on ComEd's approved year-end
2022 rate base. This results in a total cumulative revenue requirement increase of $501 million, a $986 million total revenue reduction from the requested cumulative revenue requirement increase but
remains  subject  to  annual  reconciliation  in  accordance  with  CEJA.  The  final  order  approved  the  process  and  formulas  associated  with  the  MRP  reconciliation  mechanisms.  The  ICC  did  not  approve  a
previously proposed phase-in of the ICC's approved year-over-year revenue increases, and it also denied ComEd's ability to earn a return on its pension asset.

On December 22, 2023, ComEd filed an application for rehearing on several findings in the final order including the use of the 2022 year-end rate base to establish forecast revenue requirements for 2024-
2027, ROE, pension asset return, and capital structure. On January 10, 2024, ComEd’s application for rehearing was denied on all issues except for the order’s use of the 2022 year-end rate base. On
January 31, 2024, the ICC granted ComEd's motion seeking additional clarification on the scope on rehearing, generally accepting ComEd's proposal and confirming that the rehearing will determine if the
forecasted year-end 2023 rate base should be used to set rates for 2024 through 2027 until a refiled Grid Plan is approved. A final rehearing order on that topic is statutorily required by early June 2024. On
January 10, 2024, ComEd also filed an appeal in the Illinois Appellate Court of the issues on which rehearing was denied, including but not limited to the allowed ROE and denial of a return on ComEd’s
pension asset. There is no deadline by when the appellate court must rule. On February 8, 2024, the ICC denied ComEd's request to provide clarification on other issues including the schedule for review
of  the  refiled  Grid  Plan.  ComEd  has  completed  and  placed  in  service  additional  utility  plant  assets  in  2023  and  will  continue  to  complete  and  place  in  service  additional  utility  plant  assets  prior  to  the
approval of the new Grid Plan. There are still significant unknowns, but ComEd does not currently believe that it is probable that the initially uncollected depreciation or return on the recently completed
plant will ultimately be disallowed.

In January 2022, ComEd filed a request with the ICC proposing performance metrics that would be used in determining ROE incentives and penalties in the event ComEd filed a MRP in January 2023. On
September 27, 2022, the ICC issued a final order approving seven performance metrics that provide symmetrical performance adjustments of 32 total basis points to ComEd’s rate of return on common
equity based on the extent to which ComEd achieves the annual performance goals. On November 10, 2022, the ICC granted ComEd's application for rehearing, in part. On April 5, 2023, the ICC issued its
final order on rehearing for the performance and tracking metrics proceeding, in which the ICC declined to adopt ComEd's proposed modifications to the reliability and peak load reduction performance
metrics. Efforts are underway to implement the performance metrics, which took effect on January 1, 2024. ComEd will make its initial filing in 2025 to assess performance achieved under the metrics in
2024, and to determine any ROE adjustment, which would take effect in 2026.

Carbon Mitigation Credit

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 3 — Regulatory Matters

CEJA establishes decarbonization requirements for Illinois as well as programs to support the retention and development of emissions-free sources of electricity. ComEd is required to purchase CMCs from
participating  nuclear-powered  generating  facilities  between  June  1,  2022  and  May  31,  2027.  The  price  to  be  paid  for  each  CMC  was  established  through  a  competitive  bidding  process  that  included
consumer-protection measures that capped the maximum acceptable bid amount and a formula that reduces CMC prices by an energy price index, the base residual auction capacity price in the ComEd
zone of PJM, and the monetized value of any federal tax credit or other subsidy if applicable. The consumer protection measures contained in CEJA will result in net payments to ComEd ratepayers if the
energy index, the capacity price and applicable federal tax credits or subsidy exceed the CMC contract price. In the June 2022 billing period. ComEd began issuing credits to its retail customers under its
new CMC rider. A regulatory asset is recorded for the difference between customer credits issued and the credit to be received from the participating nuclear-powered generating facilities. The balance as
of December 31, 2023 is $673 million.

Under CEJA, the costs of procuring CMCs, including carrying costs, are recovered through a rider, the Rider Carbon-Free Resource Adjustment (Rider CFRA). As originally approved by the ICC, Rider
CFRA provides for an annual reconciliation and true-up to actual costs incurred or credits received by ComEd to purchase CMCs, with any difference to be credited to or collected from ComEd’s retail
customers in subsequent periods. The difference between the net payments to (or receivables from) ComEd ratepayers and the credits received by ComEd to purchase CMCs is recorded to Purchased
power expense with an offset to the regulatory asset (or regulatory liability). On December 21, 2022, ComEd filed an amendment to Rider CFRA proposing that it recover costs or provide credits faster
than the tariff allows, implement monthly reconciliations, and allow ComEd to adjust Rider CFRA rates based not only on anticipated differences but also past payments or credits, and implement monthly
reconciliations  beginning  with  the  June  2023  delivery  period.  The  ICC  approved  the  proposal  on  January  19,  2023.  In  addition,  on  March  24,  2023,  ComEd  submitted  revisions  to  Rider  CFRA  which
clarified the methodology for calculating interest to be included in the annual reconciliation associated with the June 2022 through May 2023 delivery year. The ICC approved the proposal on April 20,
2023. On February 2, 2024, ComEd filed a petition with the ICC to initiate the reconciliation proceeding for the costs incurred in connection with the procurement of CMCs during the delivery year beginning
June 1, 2022 and extending through May 31, 2023.

Excess Deferred Income Taxes

The  ICC  initiated  a  docket  to  accelerate  and  fully  credit  to  customers  TCJA  unprotected  property-related  EDIT  no  later  than  December  31,  2025.  On  July  7,  2022,  the  ICC  issued  a  final  order  on  the
schedule for the acceleration of EDIT amortization, adopting the proposal as submitted by several parties, including ComEd, ICC Staff, the Illinois Attorney General's Office, and the Citizens Utility Board.
EDIT amortization will be credited to customers through a new rider from January 1, 2023 through December 31, 2025.

Beneficial Electrification Plan

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 3 — Regulatory Matters

On March 23, 2023, the ICC issued its final order approving the beneficial electrification plan for ComEd. The ICC rejected ComEd's request to treat a large portion of beneficial electrification costs as a
regulatory asset and ordered ComEd to seek cost recovery through the multi-year rate plan filing for 2024 and 2025, and the final formula rate reconciliation docket for 2023, rather than through a separate
charge. The order also authorized an overall annual budget of $77 million per year for the three year plan period (2023 through 2025), with flexibility to roll forward unused funds to future years within the
same plan period. On April 18, 2023, ComEd filed an application for rehearing in the beneficial electrification plan docket. The Chicago Transit Authority and City of Chicago, jointly, and the Office of the
Illinois Attorney General (ILAG) also filed applications for rehearing. On April 27, 2023, ICC staff filed a motion for clarification, seeking clarification from the ICC on the precise budget described in the final
order. On May 8, 2023, the ICC denied all applications for rehearing, and entered an amendatory order regarding the annual beneficial electrification plan budgets. ComEd has been directed to use good
faith efforts to spend $77 million annually. ComEd subsequently filed its compliance filing in May 2023, detailing project related spending, clarifying the procedure that will be used to seek stakeholder
feedback related to beneficial electrification pilot programs, and including the timeline for tariff changes required to implement the programs. ComEd and the ILAG both filed appeals of the ICC’s interim
order that addressed the permissible scope of utility beneficial electrification programs outside of transportation and the rate impact cap. The ILAG also filed an appeal seeking reversal of portions of the
ICC’s final decision. The final order partly mooted ComEd’s appeal of the interim order and ComEd has decided not to pursue the other issues. As such, ComEd moved to voluntarily dismiss its appeal and
the appellate court granted that request. The ILAG consolidated their appeals. Any ruling on the appeals, even a negative ruling removing programs from the BE Plan or lowering the overall budget of the
BE Plan, will only impact forward-looking costs.

Energy Efficiency

CEJA extends ComEd’s current cumulative annual energy efficiency MWh savings goals through 2040, adds expanded electrification measures to those goals, increases low-income commitments and
adds a new performance adjustment to the energy efficiency formula rate. ComEd expects its annual spend to increase in 2023 through 2040 to achieve these energy efficiency MWh savings goals, which
will  be  deferred  as  a  separate  regulatory  asset  that  will  be  recovered  through  the  energy  efficiency  formula  rate  over  the  weighted  average  useful  life,  as  approved  by  the  ICC,  of  the  related  energy
efficiency measures.

Energy  Efficiency  Formula  Rate  (Exelon  and  ComEd).  FEJA  allows  ComEd  to  defer  energy  efficiency  costs  (except  for  any  voltage  optimization  costs  which  are  recovered  through  the  electric
distribution formula rate) as a separate regulatory asset that is recovered through the energy efficiency formula rate over the weighted average useful life, as approved by the ICC, of the related energy
efficiency measures. ComEd earns a return on the energy efficiency regulatory asset at a rate equal to its weighted average cost of capital, which is based on a year-end capital structure and calculated
using  the  same  methodology  applicable  to  ComEd’s  electric  distribution  formula  rate.  Beginning  January  1,  2018,  the  ROE  that  ComEd  earns  on  its  energy  efficiency  regulatory  asset  is  subject  to  a
maximum downward or upward adjustment of 200 basis points if ComEd’s cumulative persisting annual MWh savings falls short of or exceeds specified percentage benchmarks of its annual incremental
savings goal. ComEd is required to file an update to its energy efficiency formula rate on or before June 1  each year, with resulting rates effective in January of the following year. The annual update is
based  on  projected  current  year  energy  efficiency  costs,  PJM  capacity  revenues,  and  the  projected  year-end  regulatory  asset  balance  less  any  related  deferred  income  taxes  (initial  year  revenue
requirement). The update also reconciles any differences between the revenue requirement in effect for the prior year and actual costs incurred from the year (annual reconciliation). The approved energy
efficiency formula rate also provides for revenue decoupling provisions similar to those in ComEd’s electric distribution formula rate.

(a) ComEd's 2024 approved revenue requirement above reflects an increase of $71 million for the initial year revenue requirement for 2024 and a increase of $47 million related to the annual reconciliation for 2022. The
revenue requirement for 2024 provides for a weighted average debt and equity return on the energy efficiency regulatory asset and rate base of 6.48% inclusive of an allowed ROE of 8.91%, reflecting the monthly
average yields for 30-year treasury bonds plus 580 basis points. The revenue requirement for the 2022 reconciliation year provides for a weighted average debt and equity return on the energy efficiency regulatory
asset and rate base of 7.47% inclusive of an allowed ROE of 10.89%, which includes an upward performance adjustment that increased the ROE. The performance adjustment can either increase or decrease the ROE
based upon the achievement of energy efficiency savings goals. See table below for ComEd's regulatory assets associated with its energy efficiency formula rate.

Maryland Regulatory Matters

Maryland Revenue Decoupling (Exelon, BGE, PHI, Pepco, and DPL). In 1998, the MDPSC approved natural gas monthly rate adjustments for BGE and in 2007, the MDPSC approved electric monthly
rate adjustments for BGE and BSAs for Pepco and DPL, all of which are decoupling mechanisms. As a result of the decoupling mechanisms, certain Operating revenues from electric and natural gas
distribution at BGE and Operating revenues from electric distribution at Pepco Maryland (see also District of Columbia Revenue Decoupling below for Pepco District of Columbia) and DPL are not impacted
by abnormal weather or usage per customer. For BGE, Pepco, and DPL, the decoupling mechanism eliminates the impacts of abnormal weather or customer usage by recognizing revenues based on an
authorized distribution amount per customer by customer class. Operating revenues from electric and natural gas distribution at BGE and Operating revenues from electric distribution at Pepco Maryland
and DPL are, however, impacted by changes in the number of customers.

Maryland Order Directing the Distribution of Energy Assistance Funds (Exelon, BGE, PHI, Pepco, and DPL). On June 15, 2021, the MDPSC issued an order authorizing the disbursal of funds to
utilities in accordance with Maryland COVID-19 relief legislation. Under this order, BGE, Pepco, and DPL received funds of $50 million, $12 million, and $8 million, respectively, in July 2021. The funds
have been used to reduce or eliminate certain qualifying past-due residential customer receivables.

EmPOWER Maryland Cost Recovery (Exelon, BGE, PHI, Pepco and DPL). On December 29, 2023, the MDPSC issued an order authorizing the next three-year program cycle for EmPOWER Maryland
and approved various proposals by the program administrators to implement new energy efficiency programs for the 2024-2026 program cycle, as well as continue operating core programs. Historically,
BGE, Pepco, and DPL deferred most of their energy efficiency program costs to a regulatory asset and either deferred most of their demand response program costs to a regulatory asset or capitalized
them.  Beginning  in  2024,  BGE,  Pepco,  and  DPL  will  begin  deferring  less  energy  efficiency  and  demand  response  program  costs  to  a  regulatory  asset. Additionally,  as  part  of  the  order,  the  MDPSC
directed BGE, Pepco, and DPL to extend the amortization of unamortized costs as of December 31, 2023 from 5 to 7 years to mitigate customer bill impacts.

District of Columbia Regulatory Matters

District  of  Columbia  Revenue  Decoupling  (Exelon,  PHI,  and  Pepco). In 2009, the DCPSC approved a BSA, which is a decoupling mechanism. As a result of the decoupling mechanism, Operating
revenues from electric distribution at Pepco District of Columbia (see also Maryland Revenue Decoupling above for Pepco Maryland) are not impacted by abnormal weather or usage per customer. The
decoupling mechanism eliminates the impacts of abnormal weather or customer usage by recognizing revenues based on an authorized distribution amount per customer by customer class. Operating
revenues from electric distribution at Pepco District of Columbia are, however, impacted by changes in the number of customers.

Note 3 — Regulatory Matters

New Jersey Regulatory Matters

Conservation Incentive Program (CIP) (Exelon, PHI, and ACE). On September 25, 2020, ACE filed an application with the NJBPU as was required seeking approval to implement a portfolio of energy
efficiency programs pursuant to New Jersey’s clean energy legislation. The filing included a request to implement a CIP that would eliminate the favorable and unfavorable impacts of weather and customer
usage patterns on distribution revenues for most customers. The CIP compares current distribution revenues by customer class to approved target revenues established in ACE’s most recent distribution
base rate case. The CIP is calculated annually and recovery is subject to certain conditions, including an earnings test and ceilings on customer rate increases.

On April 27, 2021, the NJBPU approved the settlement filed by ACE and the third parties to the proceeding. The approved settlement addresses all material aspects of ACE’s filing, including ACE’s ability
to implement the CIP prospectively effective July 1, 2021. As a result of this decoupling mechanism, operating revenues will no longer be impacted by abnormal weather or usage for most customers.
Starting in third quarter of 2021, ACE has recorded alternative revenue program revenues for its best estimate of the distribution revenue impacts resulting from future changes in CIP rates that it believes
are probable of approval by the NJBPU in accordance with this mechanism.

Termination of Energy Procurement Provisions of PPAs (Exelon, PHI, and ACE). On December 22, 2021, ACE filed with the NJBPU a petition to terminate the provisions in the PPAs to purchase
electricity from two coal-powered generation facilities located in the state of New Jersey. The petition was approved by the NJBPU on March 23, 2022. Upon closing of the transaction on March 31, 2022,
ACE recognized a liability of $203 million for the contract termination fee, which is to be paid by the end of 2024, and recognized a corresponding regulatory asset of $203 million.

As of December 31, 2023, the $49 million liability for the contract termination fee is included in Other current liabilities in Exelon's Consolidated Balance Sheet and PPA termination obligation in PHI's and
ACE's Consolidated Balance Sheets. For the year ended December 31, 2023 and 2022, ACE has paid $88 million and $66 million of the liability, which is recorded in Changes in Other assets and liabilities
in Exelon's, PHI's, and ACE's Consolidated Statements of Cash Flows.

ACE Infrastructure Investment Program Filings (Exelon, PHI, and ACE). On February 28, 2018, ACE filed with the NJBPU the Registrants' IIP proposing to seek recovery of a series of investments
through  a  new  rider  mechanism,  totaling  $338  million,  between  2019-2022  to  provide  safe  and  reliable  service  for  its  customers.  The  IIP  will  allow  for  more  timely  recovery  of  investments  made  to
modernize and enhance ACE’s electric system. On April 15, 2019, ACE entered into a settlement agreement with other parties, which allows for a recovery totaling $96 million of reliability related capital
investments from July 1, 2019 through June 30, 2023. On April 18, 2019, the NJBPU approved the settlement agreement.

On October 31, 2022, ACE filed with the NJBPU a second IIP, called “Powering the Future”, proposing to seek recovery through a new component of ACE’s rider mechanism, totaling $379 million, over the
four-year period of July 1, 2023, to June 30, 2027. The new IIP will allow ACE to invest in projects that are designed to enhance the reliability, resiliency, and safety of the service ACE provides to its
customers. On  June  15,  2023, ACE  entered  into  a  settlement  agreement  with  other  parties,  which  allows  for  a  recovery  totaling  $93  million  of  reliability  related  capital  investments  from  July  1,  2023,
through June 30, 2027. ACE will have the option of seeking approval from the NJBPU to extend the end date of the IIP beyond June 30, 2027, if ACE determines an extension is necessary.  On June 29,
2023, the NJBPU adopted the settlement agreement and issued an order approving the program.

Advanced Metering Infrastructure Filing (Exelon, PHI, and ACE). On August 26, 2020, ACE filed an application with the NJBPU as was required seeking approval to deploy a smart energy network in
alignment with New Jersey’s Energy Master Plan and Clean Energy Act. The proposal consisted of estimated costs totaling $220 million with deployment taking place over a 3-year implementation period
from approximately 2021 to 2024  that  involves  the  installation  of  an  integrated  system  of  smart  meters  for  all  customers  accompanied  by  the  requisite  communications  facilities  and  data  management
systems.

On  July  14,  2021,  the  NJBPU  approved  the  settlement  filed  by ACE  and  the  third  parties  to  the  proceeding.  The  approved  settlement  addresses  all  material  aspects  of ACE's  smart  energy  network
deployment plan, including

cost recovery of the investment costs, incremental O&M expenses, and the unrecovered balance of existing infrastructure through future distribution rates.

New  Jersey  Clean  Energy  Legislation  (Exelon,  PHI,  and  ACE). On  May  23,  2018,  New  Jersey  enacted  legislation  that  established  and  modified  New  Jersey’s  clean  energy  and  energy  efficiency
programs and solar and RPS. On the same day, New Jersey enacted legislation that established a ZEC program that provides compensation for nuclear plants that demonstrate to the NJBPU that they
meet certain requirements. Under the legislation, the NJBPU will issue ZECs to the qualifying nuclear power plants and the electric distribution utilities in New Jersey, including ACE, will be required to
purchase those ZECs. ACE began collecting from retail distribution customers, through a non-bypassable charge, all costs associated with the procurement of the ZECs effective April 18, 2019.

Other Federal Regulatory Matters

FERC Audit (Exelon and ComEd). The Utility Registrants are subject to periodic audits and investigations by FERC. FERC’s Division of Audits and Accounting initiated a nonpublic audit of ComEd in
April 2021 evaluating ComEd’s compliance with (1) approved terms, rates and conditions of its federally regulated service; (2) accounting requirements of the Uniform System of Accounts; (3) reporting
requirements of the FERC Form 1; and (4) the requirements for record retention. The audit period extends back to January 1, 2017. During the first quarter of 2023, ComEd was provided with information
from FERC about several potential findings, including ComEd's methodology regarding the allocation of certain overhead costs to capital under FERC regulations. Based on the preliminary findings and
discussions with FERC staff, ComEd determined that a loss was probable and recorded a regulatory liability to reflect its best estimate of that loss in the first quarter of 2023.

On July 27, 2023, FERC issued a final audit report which included, among other things, findings and recommendations related to ComEd's methodology regarding the allocation of certain overhead costs
to capitalized construction costs under FERC regulations, including a suggestion that refunds may be due to customers for amounts collected in previous years. On August 28, 2023, ComEd filed a formal
notice of the issues it will contest. On December 14, 2023, FERC appointed a settlement judge for the contested overhead allocation findings. The final outcome and resolution of any contested audit issues
as well as a reasonable estimate of potential future losses cannot be accurately estimated at this stage; however, the final resolution of these matters could result in recognition of future losses, above the
amounts currently accrued, that could be material to the Exelon and ComEd financial statements.

Regulatory Assets and Liabilities

Regulatory assets represent incurred costs that have been deferred because of their probable future recovery from customers through regulated rates. Regulatory liabilities represent the excess recovery
of costs or accrued credits that have been deferred because it is probable such amounts will be returned to customers through future regulated rates or represent billings in advance of expenditures for
approved regulatory programs.

The regulatory agreements with the ICC and PAPUC dictate obligations related to the shortfall or excess of NDT funds necessary for decommissioning the former ComEd units on a unit-by-unit basis and
the former PECO units in total.

For the former PECO units, given the symmetric settlement provisions that allow for continued recovery of decommissioning costs from PECO customers in the event of a shortfall and the obligation for
Constellation to ultimately return excess funds to PECO customers (on an aggregate basis for all seven units), decommissioning-related activities prior to separation on February 1, 2022 were generally
offset in Exelon’s Consolidated

Note 3 — Regulatory Matters

Statements  of  Operations  and  Comprehensive  Income  with  an  offsetting  adjustment  to  the  regulatory  liabilities  or  regulatory  assets  and  an  equal  noncurrent  affiliate  receivable  from  or  payable  to
Generation  at  PECO.  Following  the  separation,  decommissioning-related  activities  result  in  an  adjustment  to  the  Receivable  related  to  Regulatory Agreement  Units  and  an  equal  adjustment  to  the
regulatory liabilities or regulatory assets at PECO.

For the former ComEd units, given no further recovery from ComEd customers is permitted and Constellation retains an obligation to ultimately return excess funds to ComEd customers (on a unit-by-unit
basis), to the extent excess funds are expected for each unit, decommissioning-related activities prior to separation on February 1, 2022 were offset in the Consolidated Statements of Operations and
Comprehensive  Income  with  an  offsetting  adjustment  to  regulatory  liabilities  and  noncurrent  affiliate  receivable  from  Generation  at  ComEd.  Following  the  separation,  decommissioning-related  activities
result in an adjustment to the Receivable related to Regulatory Agreement Units and an equal adjustment to the regulatory liabilities at ComEd. However, given the asymmetric settlement provision that
does not allow for continued recovery from ComEd customers in the event of a shortfall, recognition of a regulatory asset at ComEd is not permissible.

Capitalized Ratemaking Amounts Not Recognized

The  following  table  presents  authorized  amounts  capitalized  for  ratemaking  purposes  related  to  earnings  on  shareholders’  investment  that  are  not  recognized  for  financial  reporting  purposes  in  the

4. Revenue from Contracts with Customers (All Registrants)

The Registrants recognize revenue from contracts with customers to depict the transfer of goods or services to customers at an amount that the entities expect to be entitled to in exchange for those goods
or services. The primary sources of revenue include regulated electric and gas tariff sales, distribution, and transmission services. The performance obligations, revenue recognition, and payment terms
associated with these sources of revenue are further discussed in the table below. There are no significant financing components for these sources of revenue and no variable consideration.

Unless otherwise noted, for each of the significant revenue categories and related performance obligations described below, the Registrants have the right to consideration from the customer in an amount
that corresponds directly with the value transferred to the customer for the performance completed to date. Therefore, the Registrants generally recognize revenue in the amount for which they have the
right to invoice the customer. As a result, there are generally no significant judgments used in determining or allocating the transaction price.

Note 4 — Revenue from Contracts with Customers

Revenue Source

Regulated Electric and Gas Tariff
Sales

Regulated Transmission Services

Description
Sales of electricity and electricity distribution
services (the Utility Registrants) and natural gas
and gas distribution services (PECO, BGE, and
DPL) to residential, commercial, industrial, and
governmental customers through regulated tariff
rates approved by state regulatory commissions.

The Utility Registrants provide open access to
their transmission facilities to PJM, which directs
and controls the operation of these transmission
facilities and accordingly compensates the Utility
Registrants pursuant to filed tariffs at cost-based
rates approved by FERC.

Performance Obligation

Timing of Revenue Recognition

Payment Terms

Delivery of electricity and/or natural gas.

Various including (i) Network Integration
Transmission Services (NITS), (ii)
scheduling, system control and dispatch
services, and (iii) access to the wholesale
grid.

Over time (each day) as the electricity
and/or natural gas is delivered to
customers. Tariff sales are generally
considered daily contracts as
customers can discontinue service at
any time.

 (a)

Within the month following
delivery of the electricity or
natural gas to the customer.

Over time utilizing output methods to
measure progress towards
completion.

 (b)

Paid weekly by PJM.

__________
(a) Electric  and  natural  gas  utility  customers  have  the  choice  to  purchase  electricity  or  natural  gas  from  competitive  electric  generation  and  natural  gas  suppliers.  While  the  Utility  Registrants  are  required  under  state
legislation to bill their customers for the supply and distribution of electricity and/or natural gas, they recognize revenue related only to the distribution services when customers purchase their electricity or natural gas
from competitive suppliers.

(b) Passage of time is used for NITS and access to the wholesale grid and MWhs of energy transported over the wholesale grid is used for scheduling, system control and dispatch services.

The Utility Registrants do not incur any material costs to obtain or fulfill contracts with customers.

Contract Liabilities

The Registrants record contract liabilities when consideration is received or due prior to the satisfaction of the performance obligations. The Registrants record contract liabilities in Other current liabilities
and Other noncurrent liabilities in the Registrants' Consolidated Balance Sheets.

On  July  1,  2020,  Pepco,  DPL,  and ACE  each  entered  into  a  collaborative  arrangement  ("Agreement")  with  an  unrelated  owner  and  manager  of  communication  infrastructure  (the  "Buyer").  Under  this
arrangement, Pepco, DPL, and ACE sold a 60% undivided interest in their respective portfolios of transmission tower attachment agreements with telecommunications companies to the Buyer, in addition
to transitioning management of the day-to-day operations of the jointly-owned agreements to the Buyer for 35 years, while retaining the safe and reliable operation of its utility assets. In return, Pepco, DPL,
and ACE will provide the Buyer limited access on the portion of the towers where the equipment resides for the purposes of managing the agreements for the benefit of Pepco, DPL, ACE, and the Buyer.
Pursuant to the Agreement, Pepco, DPL, and ACE have the option ("Payment Option"), but not obligation, to sell two additional 10% undivided interests in the tower attachment agreements to the Buyer
for specified consideration. In addition, for an initial period of three years and two, two-year extensions that are subject to certain conditions, the Buyer has the exclusive right to enter into new agreements
with telecommunications companies and to receive a specified undivided percentage interest in those new agreements as set forth in the Agreement. Pepco, DPL, and ACE received cash and recorded
contract liabilities as of July 1, 2020. The revenue attributable to this arrangement will be recognized as Electric operating revenues over the 35 years under the Agreement.

Note 4 — Revenue from Contracts with Customers

During  the  fourth  quarter  of  2023,  Pepco,  DPL,  and ACE  entered  into  an  amendment  to  the Agreement  (“Amendment”)  to  modify  the  terms  of  the  Payment  Option  and  the  conditions  to  exercise  the
exclusive right extensions. Concurrently, Pepco, DPL and ACE exercised both Payment Options which also triggered the extension of the exclusive right period until 2027. The Amendment and executed
Payment  Options  represent  a  contract  modification  that  is  accounted  for  prospectively  in  accordance  with  authoritative  guidance.  Pepco,  DPL  and ACE  received  cash  and  recorded  an  increase  to  the
contract  liabilities  as  of  December  31,  2023  as  shown  in  the  table  below.  The  revenue  will  be  recognized  as  Electric  operating  revenues  over  the  remaining  term  of  the Agreement  (approximately  31
years).

The  following  table  provides  a  rollforward  of  the  contract  liabilities  reflected  in  Exelon's,  PHI's,  Pepco's,  DPL's,  and ACE'S  Consolidated  Balance  Sheets. As  of  December  31,  2023,  2022,  and  2021,
ComEd's, PECO's, and BGE's contract liabilities were not material.

Transaction Price Allocated to Remaining Performance Obligations

The following table shows the amounts of future revenues expected to be recorded in each year for performance obligations that are unsatisfied or partially unsatisfied as of December 31, 2023. This
disclosure only includes contracts for which the total consideration is fixed and determinable at contract inception. The average contract term varies by customer type and commodity but ranges from one
month to several years.

This disclosure excludes the Utility Registrants' gas and electric tariff sales contracts and transmission revenue contracts as they generally have an original expected duration of one year or less and,
therefore, do not contain any future, unsatisfied performance obligations to be included in this disclosure.

The Registrants disaggregate revenue recognized  from  contracts  with  customers  into  categories  that  depict  how  the  nature,  amount,  timing,  and  uncertainty  of  revenue  and  cash  flows  are  affected  by
economic factors. See Note 5 — Segment Information for the presentation of the Registrant's revenue disaggregation.

5. Segment Information (All Registrants)

Operating segments for each of the Registrants are determined based on information used by the CODMs in deciding how to evaluate performance and allocate resources at each of the Registrants.

(Dollars in millions, except per share data unless otherwise noted)

Note 5 — Segment Information

Exelon has six reportable segments, which include ComEd, PECO, BGE, and PHI's three reportable segments consisting of Pepco, DPL, and ACE. ComEd, PECO, BGE, Pepco, DPL, and ACE each
represent  a  single  reportable  segment,  and  as  such,  no  separate  segment  information  is  provided  for  these  Registrants.  Exelon,  ComEd,  PECO,  BGE,  Pepco,  DPL,  and ACE's  CODMs  evaluate  the
performance of and allocate resources to the segments based on net income.

The  separation  of  Constellation  Energy  Corporation,  including  Generation  and  its  subsidiaries,  meets  the  criteria  for  discontinued  operations  and  as  such,  results  of  operations  are  presented  as
discontinued operations and have been excluded from continuing operations for all periods presented. Furthermore, the reportable segment information related to the discontinued operations has been
excluded from the tables presented below. See Note 2 — Discontinued Operations for additional information.

An analysis and reconciliation of the Registrants' reportable segment information to the respective information in the consolidated financial statements for the years ended December 31, 2023, 2022, and
2021 is as follows:

Electric and Gas Revenue by Customer Class (Utility Registrants):

The  following  tables  disaggregate  the  Registrants'  revenues  recognized  from  contracts  with  customers  into  categories  that  depict  how  the  nature,  amount,  timing,  and  uncertainty  of  revenue  and  cash
flows are affected by economic factors. For the Utility Registrants, the disaggregation of revenues reflects the two primary utility services of electric sales and natural gas sales (where applicable), with
further disaggregation of these tariff sales provided by major customer groups. Exelon's disaggregated revenues are consistent with the Utility Registrants, but exclude any intercompany revenues.

_________
(a) For ComEd, the change in current period provision for expected credit losses is primarily a result of increased receivable balances.
(b) For BGE, DPL and ACE, the change in current period provision for expected credit losses is primarily a result of decreased receivable balances.
(c) For Pepco the change in current period provision for expected credit losses is primarily a result of receivables increasing at a slower pace versus the prior period.
(d) For PECO and BGE the change in write-offs is primarily a result of increased disconnection activities.
(e) For PHI, ACE, and Pepco, write-offs are primarily attributable to the termination of the moratorium in the service territory for each operating company, which beginning in 2020, prevented customer disconnections for

non-payment. Disconnection activities across the service territories resumed from September 2020 through January 2022, resulting in write-offs of aged accounts receivable.

(f) For DPL, the change in write-offs is primarily attributable to unfavorable customer payment behavior.
(g) Recoveries were not material to the Registrants.

Note 11 — Asset Impairments

11. Asset Impairments (Exelon and BGE)

In the third quarter of 2022, a review of the impacts of COVID-19 on office use resulted in plans to cease the renovation and dispose of an office building at BGE before the asset was placed into service.
BGE determined that the carrying value was not recoverable and that its fair value was less than carrying value. As a result, in 2022, a pre-tax impairment charge of $48 million was recorded in Operating
and maintenance expense in Exelon’s and BGE’s Consolidated Statements of Operations and Comprehensive Income. The fair value used in the analysis was based on an estimate of an expected sales
price. The office building met all of the criteria for classification as held for sale as of December 31, 2023, and therefore is reported within Other current assets in Exelon’s and BGE’s Balance Sheets as of
December 31, 2023.

12. Intangible Assets

Goodwill (Exelon, ComEd, PHI, Pepco, DPL, and ACE)

The following table presents the gross amount, accumulated impairment loss, and carrying amount of Goodwill at Exelon, ComEd, and PHI at December 31, 2023 and 2022. There were no additions or
impairments during the years ended December 31, 2023 and 2022.

Goodwill is not amortized, but is subject to an assessment for impairment at least annually, or more frequently if events occur or circumstances change that would more likely than not reduce the fair value
of ComEd's and PHI's reporting units below their carrying amounts. A reporting unit is an operating segment or one level below an operating segment (known as a component) and is the level at which
goodwill is assessed for impairment. A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and its operating
results are regularly reviewed by segment management. ComEd has a single operating segment. PHI's operating segments are Pepco, DPL, and ACE. See Note 5 — Segment Information for additional
information.  There  is  no  level  below  these  operating  segments  for  which  operating  results  are  regularly  reviewed  by  segment  management.  Therefore,  the  ComEd,  Pepco,  DPL,  and ACE  operating
segments are also considered reporting units for goodwill impairment assessment purposes. Exelon's and ComEd's $2.6 billion of goodwill has been assigned entirely to the ComEd reporting unit, while
Exelon's and PHI's $4.0 billion of goodwill has been assigned to the Pepco, DPL, and ACE reporting units in the amounts of $2.1 billion, $1.4 billion, and $0.5 billion, respectively.

Entities assessing goodwill for impairment have the option of first performing a qualitative assessment to determine whether a quantitative assessment is necessary. As part of the qualitative assessments,
Exelon,  ComEd,  and  PHI  evaluate,  among  other  things,  management's  best  estimate  of  projected  operating  and  capital  cash  flows  for  their  businesses,  outcomes  of  recent  regulatory  proceedings,
changes  in  certain  market  conditions,  including  the  discount  rate  and  regulated  utility  peer  EBITDA  multiples,  and  the  passing  margin  from  their  last  quantitative  assessments  performed.  If  an  entity
bypasses the qualitative assessment, a quantitative, fair value-based assessment is performed, which compares the fair value of the reporting unit to its carrying amount, including goodwill. If the carrying
amount of the reporting unit exceeds its fair value, the entity recognizes an impairment charge, which is limited to the amount of goodwill allocated to the reporting unit.

Application of the goodwill impairment assessment requires management judgment, including the identification of reporting units and determining the fair value of the reporting unit, which management
estimates using a weighted combination of a discounted cash flow analysis and a market multiples analysis. Significant assumptions used in these fair value analyses include discount and growth rates,

performance and transactions, projected operating and capital cash flows for ComEd's, Pepco's, DPL's, and ACE's businesses, and the fair value of debt.

2023 and 2022 Goodwill Impairment Assessment. ComEd and PHI qualitatively determined that it was more likely than not that the fair values of their reporting units exceeded their carrying values and,
therefore, did not perform quantitative assessments as of November 1, 2023 and 2022. The last quantitative assessments performed for PHI was as of November 1, 2018. On December 14, 2023, due to
the issuance of the ICC's final order rejecting ComEd’s proposed Grid Plan and establishing retail rates for 2024-2027 as further discussed in Note 3 — Regulatory Matters, Exelon’s stock price decreased
approximately  10%  triggering  an  interim  quantitative  assessment  for  potential  goodwill  impairment  at  ComEd.  ComEd  performed  a  quantitative  assessment  as  of  December  31,  2023,  comparing  the
estimated fair value of ComEd to its carrying value, and determined there was no indication of goodwill impairment.

While the annual and interim assessments indicated no impairments, certain assumptions used to estimate reporting unit fair values are highly sensitive to changes. Adverse regulatory actions or changes
in significant assumptions could potentially result in future impairments of Exelon's, ComEd's, and PHI’s goodwill, which could be material.

Other Intangible Assets and Liabilities (Exelon and PHI)

Exelon’s other intangible assets, included in Other current assets and Other deferred debits and other assets in the Consolidated Balance Sheets, consisted of the following at December 31, 2023 and
2022.  Exelon's  and  PHI's  other  intangible  liabilities,  included  in  current  and  noncurrent  Unamortized  energy  contract  liabilities  in  their  Consolidated  Balance  Sheets,  consisted  of  the  following  at
December  31,  2023  and  2022.  The  intangible  assets  and  liabilities  shown  below  are  amortized  on  a  straight-line  basis,  except  for  unamortized  energy  contracts  which  are  amortized  in  relation  to  the
expected realization of the underlying cash flows:

Note 13 — Income Taxes

(e) For  Exelon,  the  higher  state  income  taxes,  net  of  federal  income  tax  benefit,  is  primarily  due  to  the  long-term  marginal  state  income  tax  rate  change  of  $67  million  and  the  recognition  of  a  valuation  allowance  of
$40 million against the net deferred tax asset position for certain standalone state filing jurisdictions, partially offset by a one-time impact associated with a state tax benefit of $43 million and indemnification adjustments
pursuant to the Tax Matters Agreement of $11 million as a result of the separation. For PECO, the higher state income taxes, net of federal income tax benefit, related to a one-time expense of $38 million attributable to
the change in the Pennsylvania corporate income tax rate.

(f) For Exelon, reflects the income tax expense related to the write-off of federal tax credits subject to recapture of $15 million as a result of the separation.
(g) For Exelon, reflects the nondeductible transaction costs of approximately $12 million arising as part of the separation and indemnification adjustments pursuant to the Tax Matters Agreement of $9 million.
(h) For PECO, the lower effective tax rate is primarily related to plant basis differences attributable to tax repair deductions. For BGE, the income tax benefit is primarily due to the Maryland multi-year plan which resulted in
the acceleration of certain income tax benefits. For Pepco, the lower effective tax rate is primarily related to the acceleration of certain income tax benefits due to transmission and distribution rate case settlements. For
DPL, the higher effective tax rate is primarily related to a state income tax expense, net of federal income tax benefit, due to the recognition of a valuation allowance of approximately $31 million against a deferred tax
asset associated with Delaware net operating loss carryforwards as a result of a change in Delaware tax law. For ACE, the income tax benefit is primarily due to a distribution rate case settlement which allows ACE to
retain certain tax benefits.

Tax Differences and Carryforwards

The tax effects of temporary differences and carryforwards, which give rise to significant portions of the deferred tax assets (liabilities), at December 31, 2023 and 2022 are presented below:

pending court cases involving other taxpayers. The unrecognized tax benefit, if recognized, may be included in future base rates and that portion would have no impact to the effective tax rate.

(a) At December 31, 2023, Exelon classified $21 million and $41 million of the interest receivable as current and noncurrent, respectively, based on the expected timing for settlement in cash. At December 31, 2023, Exelon

recorded a receivable of $5 million in noncurrent Other assets in the Consolidated Balance Sheet for Constellation's share of net interest for periods prior to the separation.

(b) At December 31, 2022, the interest receivable balance is not expected to be settled in cash within the next twelve months and is therefore classified as a noncurrent receivable. At December 31, 2022, Exelon recorded a

receivable of $1 million in noncurrent Other assets in the Consolidated Balance Sheet for Constellation's share of net interest for periods prior to the separation.

The Registrants did not record material interest and penalty expense related to tax positions reflected in their Consolidated Balance Sheets. Interest expense and penalty expense are recorded in Interest
expense, net and Other, net, respectively, in Other income and deductions in the Registrants Consolidated Statements of Operations and Comprehensive Income.

Other Tax Matters

Separation (Exelon)

In the first quarter of 2022, in connection with the separation, Exelon recorded an income tax expense related to continuing operations of $148 million primarily due to the long-term marginal state income
tax rate change of $54 million discussed further below, the recognition of valuation allowances of approximately $40 million against the net deferred tax assets positions for certain standalone state filing
jurisdictions, the write-off of federal and state tax credits subject to recapture of $17 million, and nondeductible transaction costs for federal and state taxes of $24 million.

Tax Matters Agreement (Exelon)

In  connection  with  the  separation,  Exelon  entered  into  a  TMA  with  Constellation.  The  TMA  governs  the  respective  rights,  responsibilities,  and  obligations  between  Exelon  and  Constellation  after  the
separation with respect to tax liabilities, refunds and attributes for open tax years that Constellation was part of Exelon’s consolidated group for U.S. federal, state, and local tax purposes.

Table of Contents

(Dollars in millions, except per share data unless otherwise noted)

Note 13 — Income Taxes

Indemnification for Taxes. As  a  former  subsidiary  of  Exelon,  Constellation  has  joint  and  several  liability  with  Exelon  to  the  IRS  and  certain  state  jurisdictions  relating  to  the  taxable  periods  prior  to  the
separation. The TMA specifies that Constellation is liable for their share of taxes required to be paid by Exelon with respect to taxable periods prior to the separation to the extent Constellation would have
been responsible for such taxes under the existing Exelon tax sharing agreement. In 2023, Exelon remitted $9 million of payments to Constellation. At December 31, 2023, Exelon recorded a payable of
$11 million in Other current liabilities that is due to Constellation.

Tax Refunds. The TMA specifies that Constellation is entitled to their share of any future tax refunds claimed by Exelon with respect to taxable periods prior to the separation to the extent that Constellation
would have received such tax refunds under the existing Exelon tax sharing agreement.

Tax Attributes. At the date of separation certain tax attributes, primarily pre-closing tax credit carryforwards, that were generated by Constellation were required by law to be allocated to Exelon. The TMA
also provides that Exelon will reimburse Constellation when those allocated tax attribute carryforwards are utilized. In 2023, Exelon remitted $21 million of payments to Constellation for the utilization of
pre-closing  tax  credit  carryforwards.  At  December  31,  2023,  Exelon  recorded  a  payable  of  $182  million  and  $331  million  in  Other  current  liabilities  and  Other  deferred  credits  and  other  liabilities,
respectively, in the Consolidated Balance Sheet for tax attribute carryforwards that are expected to be utilized and reimbursed to Constellation.

Corporate Alternative Minimum Tax (All Registrants)

On August 16, 2022, the IRA was signed into law and implemented a new corporate alternative minimum tax (CAMT) that imposes a 15.0% tax on modified GAAP net income. Corporations are entitled to
a tax credit (minimum tax credit) to the extent the CAMT liability exceeds the regular tax liability. This amount can be carried forward indefinitely and used in future years when regular tax exceeds the
CAMT.

Based  on  the  existing  statue,  Exelon  and  each  of  the  Utility  Registrants  will  be  subject  to  and  will  report  the  CAMT  on  a  separate  Registrant  basis  in  the  Consolidated  Statements  of  Operations  and
Comprehensive  Income  and  the  Consolidated  Balance  Sheets.  The  deferred  tax  asset  related  to  the  minimum  tax  credit  carryforward  will  be  realized  to  the  extent  Exelon’s  consolidated  deferred  tax
liabilities exceed the minimum tax credit carryforward. Exelon’s deferred tax liabilities are expected to exceed the minimum tax credit carryforward for the foreseeable future and thus no valuation allowance
is required. Exelon is continuing to assess the financial statement impacts of the IRA and will update estimates based on future guidance issued by the U.S. Treasury.

Long-Term Marginal State Income Tax Rate (All Registrants)

Quarterly, Exelon reviews and updates its marginal state income tax rates for material changes in state tax laws and state apportionment. The Registrants remeasure their existing deferred income tax
balances to reflect the changes in marginal rates, which results in either an increase or a decrease to their net deferred income tax liability balances. Utility Registrants record corresponding regulatory
liabilities or assets to the extent such amounts are probable of settlement or recovery through customer rates and an adjustment to income tax expense for all other amounts. In the third quarter of 2023,
Exelon updated its marginal state income tax rates for changes in state apportionment. The changes in marginal rates in the third quarter resulted in a decrease of $54 million to the deferred tax liability at
Exelon, and a corresponding adjustment to income tax expense, net of federal taxes. There were no impacts to ComEd, BGE, PHI, Pepco, DPL, and ACE for the years ended December 31, 2023, 2022,
and 2021.

On July 8, 2022, Pennsylvania enacted House Bill 1342, which will permanently reduce the corporate income tax rate from 9.99% to 4.99%. The tax rate will be reduced to 8.99% for the 2023 tax year.
Starting with the 2024 tax year, the rate is reduced by 0.50% annually until it reaches 4.99% in 2031. As a result of the rate change, in the

Note 13 — Income Taxes

third quarter of 2022, Exelon and PECO recorded a one-time decrease to deferred income taxes of $390 million with a corresponding decrease to the deferred income taxes regulatory asset of $428 million
for the amounts that are expected to be settled through future customer rates and an increase to income tax expense of $38 million (net of federal taxes). The tax rate decrease is not expected to have a
material ongoing impact to Exelon’s and PECO’s financial statements. There were no changes to PECO's marginal state income tax rates for the years ended December 31, 2022, and 2021.

Allocation of Tax Benefits (All Registrants)

The Utility Registrants are party to an agreement with Exelon and other subsidiaries of Exelon that provides for the allocation of consolidated tax liabilities and benefits (Tax Sharing Agreement). The Tax
Sharing Agreement provides that each party is allocated an amount of tax similar to that which would be owed had the party been separately subject to tax. In addition, any net federal and state benefits
attributable to Exelon are reallocated to the other Registrants. That allocation is treated as a contribution from Exelon to the party receiving the benefit.

The following table presents the allocation of tax benefits from Exelon under the Tax Sharing Agreement, for the year ended December 31, 2023, 2022, and 2021.

14. Retirement Benefits (All Registrants)

Exelon sponsors defined benefit pension and OPEB plans. Substantially all non-union employees and electing union employees hired on or after January 1, 2001 participate in cash balance pension plans.
Effective January 1, 2009, substantially all newly-hired union-represented employees participate in cash balance pension plans. Effective February 1, 2018 for most newly-hired BSC non-represented, non-
craft, employees, January 1, 2021 for most newly-hired utility management employees, and for certain newly-hired union employees pursuant to their collective bargaining agreements, these newly-hired
employees are not eligible for pension benefits, and will instead be eligible to receive an enhanced non-discretionary employer contribution in an Exelon defined contribution savings plan. Effective January
1,  2018,  most  newly-hired  non-represented,  non-craft,  employees  are  not  eligible  for  OPEB  benefits  and  employees  represented  by  Local  614  are  not  eligible  for  retiree  health  care  benefits.  Effective
January 1, 2021, most non-represented, non-craft, employees who are under the age of 40 are not eligible for retiree health care benefits. Effective January 1, 2022, management employees retiring on or
after that date are no longer eligible for retiree life insurance benefits.

Effective February 1, 2022, in connection with the separation, pension and OPEB obligations and assets for current and former employees of the Constellation business and certain other former employees
of Exelon and its subsidiaries transferred to pension and OPEB plans and trusts maintained by Constellation or its subsidiaries. The Exelon New England Union Employees Pension Plan and Constellation
Mystic Power, LLC Union Employees Pension Plan Including Plan A and Plan B were transferred. The following OPEB plans were also transferred: Constellation Mystic Power, LLC Post-Employment
Medical Savings Account Plan; Exelon New England Union Post-Employment Medical Savings Account Plan; and the Nine Mile Point Nuclear Station, LLC Medical Care and Prescription Drug Plan for
Retired Employees.

As a result of the separation, Exelon restructured certain of its qualified pension plans. Pension obligations and assets for current and former employees continuing with Exelon and who were participants in
the Exelon Employee Pension Plan for Clinton, TMI, and Oyster Creek, Pension Plan of Constellation Energy Nuclear Group, LLC, and Nine Mile Point Pension Plan were merged into the Pension Plan of
Constellation Energy

Group, Inc, which was subsequently renamed, Exelon Pension Plan (EPP). Exelon employees who participated in these plans prior to the separation now participate in the EPP. The merging of the plans
did not change the benefits offered to the plan participants and, thus, had no impact on Exelon's pension obligations.

Note 14 — Retirement Benefits

Exelon’s traditional and cash balance pension plans are intended to be tax-qualified defined benefit plans. Exelon has elected that the trusts underlying these plans be treated as qualified trusts under the
IRC. If certain conditions are met, Exelon can deduct payments made to the qualified trusts, subject to certain IRC limitations.

Benefit Obligations, Plan Assets, and Funded Status

As of February 1, 2022, in connection with the separation, Exelon's pension and OPEB plans were remeasured. The remeasurement and separation resulted in a decrease to the Pension obligation, net of
plan assets, of $921 million and a decrease to the OPEB obligation of $893 million. Additionally, AOCI decreased by $1,994 million (after-tax) and Regulatory assets and liabilities increased by $14 million
and $5 million, respectively. Key assumptions were held consistent with the year end December 31, 2021 assumptions with the exception of the discount rate.

During the first quarter of 2023, Exelon received an updated valuation of its pension and OPEB to reflect actual census data as of January 1, 2023. This valuation resulted in an increase to the pension
obligation of $27 million and an increase to the OPEB obligations of $2 million. Additionally, AOCI increased by $10 million (after-tax) and Regulatory assets and liabilities increased by $18 million and $1
million, respectively.

The following tables provide a rollforward of the changes in the benefit obligations and plan assets of Exelon for the most recent two years for all plans combined:

Note 14 — Retirement Benefits

Cost Allocation to Exelon Subsidiaries

All Registrants account for their participation in Exelon’s pension and OPEB plans by applying multi-employer accounting. Exelon allocates costs related to its pension and OPEB plans to its subsidiaries
based on both active and retired employee participation in each plan.

The amounts below represent the Registrants' allocated pension and OPEB costs (benefit). For Exelon, the service cost component is included in Operating and maintenance expense and Property, plant,
and equipment, net while the non-service cost components are included in Other, net and Regulatory assets. For the Utility Registrants, the service cost and non-service cost components are included in
Operating and maintenance expense and Property, plant, and equipment, net in their consolidated financial statements.

Exelon  recognizes  the  overfunded  or  underfunded  status  of  defined  benefit  pension  and  OPEB  plans  as  an  asset  or  liability  on  its  Consolidated  Balance  Sheets,  with  offsetting  entries  to AOCI  and
Regulatory assets (liabilities). A portion of current year actuarial (gains) losses and prior service costs (credits) is capitalized in Exelon’s Consolidated Balance Sheets to reflect the expected regulatory
recovery  of  these  amounts,  which  would  otherwise  be  recorded  to  AOCI.  The  following  tables  provide  the  components  of  AOCI  and  Regulatory  assets  (liabilities)  for  Exelon  for  the  years  ended

For pension benefits, Exelon amortizes its unrecognized prior service costs (credits) and certain actuarial (gains) losses, as applicable, based on participants’ average remaining service periods.

For OPEB, Exelon amortizes its unrecognized prior service costs (credits) over participants’ average remaining service period to benefit eligibility age and amortizes certain actuarial (gains) losses over
participants’ average remaining service period to expected retirement. The resulting average remaining service periods for pension and OPEB were as follows:

The measurement of the plan obligations and costs of providing benefits under Exelon’s defined benefit and OPEB plans involves various factors, including the development of valuation assumptions and
inputs  and  accounting  policy  elections.  The  measurement  of  benefit  obligations  and  costs  is  impacted  by  several  assumptions  and  inputs,  as  shown  below,  among  other  factors.  When  developing  the
required assumptions, Exelon considers historical information as well as future expectations.

Expected Rate of Return. In determining the EROA, Exelon considers historical economic indicators (including inflation and GDP growth) that impact asset returns, as well as expectations regarding future
long-term capital market performance, weighted by Exelon’s target asset class allocations.

Mortality. The mortality assumption is composed of a base table that represents the current expectation of life expectancy of the population adjusted by an improvement scale that attempts to anticipate
future improvements in life expectancy. For the years ended  December 31, 2023 and 2022, Exelon’s mortality assumption utilizes the SOA 2019 base table (Pri-2012) and MP-2021 improvement scale
adjusted to use Proxy SSA ultimate improvement rates.

For Exelon, the following assumptions were used to determine the benefit obligations for the plans as of December 31, 2023 and 2022. Assumptions used to determine year-end benefit obligations are the
assumptions used to estimate the subsequent year’s net periodic benefit costs.

Contributions

Exelon allocates contributions related to its ECRP and PPBU pension plans and East and West OPEB plans to its subsidiaries based on accounting cost. For the EPP pension plan, PHI Qualified, and PHI
PRW plans, pension and OPEB contributions are allocated to the subsidiaries based on employee participation (both active and retired). For Exelon, in connection with the separation, additional qualified
pension contributions of $207 million and $33 million were completed on February 1, 2022 and March 2, 2022, respectively. The following table provides contributions to the pension and OPEB plans:

Management considers various factors when making pension funding decisions, including actuarially determined minimum contribution requirements under ERISA, contributions required to avoid benefit
restrictions and at-risk status as defined by the Pension Protection Act of 2006 (the "Act"), management of the pension obligation, and regulatory implications. The Act requires the attainment of certain
funding  levels  to  avoid  benefit  restrictions  (such  as  an  inability  to  pay  lump  sums  or  to  accrue  benefits  prospectively),  and  at-risk  status  (which  triggers  higher  minimum  contribution  requirements  and
participant  notification).  The  projected  contributions  below  reflect  a  funding  strategy  to  make  annual  contributions  with  the  objective  of  achieving  100%  funded  status  on  an ABO  basis  over  time.  This
funding strategy helps minimize volatility of future period required pension contributions. Based on this funding strategy and current market conditions, which are subject to change, Exelon’s estimated
annual  qualified  pension  contributions  will  be  approximately  $93  million  in  2024.  Unlike  the  qualified  pension  plans,  Exelon’s  non-qualified  pension  plans  are  not  funded,  given  they  are  not  subject  to
statutory minimum contribution requirements.

While OPEB plans are also not subject to statutory minimum contribution requirements, Exelon does fund certain of its plans. For Exelon's funded OPEB plans, contributions generally equal accounting
costs, however, Exelon’s management has historically considered several factors in determining the level of contributions to its OPEB plans, including liabilities management, levels of benefit claims paid,
and regulatory implications (amounts deemed prudent to meet regulatory expectations and best assure continued rate recovery). The amounts below include benefit payments related to unfunded plans.

The following table provides all Registrants' planned contributions to the qualified pension plans, planned benefit payments to non-qualified pension plans, and planned contributions to OPEB plans in 2024:

Investment Strategy. On a regular basis, Exelon evaluates its investment strategy to ensure plan assets will be sufficient to pay plan benefits when due. As part of this ongoing evaluation, Exelon may
make changes to its targeted asset allocation and investment strategy.

Exelon has developed and implemented a liability hedging investment strategy for its qualified pension plans that has reduced the volatility of its pension assets relative to its pension liabilities. Exelon is
likely to continue to gradually increase the liability hedging portfolio as the funded status of its plans improves. The overall objective is to achieve attractive risk-adjusted returns that will balance the liquidity
requirements of the plans’ liabilities while striving to minimize the risk of significant losses. Trust assets for Exelon’s OPEB plans are managed in a diversified investment strategy that prioritizes maximizing
liquidity and returns while minimizing asset volatility.

Actual  asset  returns  have  an  impact  on  the  costs  reported  for  the  Exelon-sponsored  pension  and  OPEB  plans.  The  actual  asset  returns  across  Exelon’s  pension  and  OPEB  plans  for  the  year  ended
December 31, 2023 were 7.73% and 9.20%, respectively, compared to an expected long-term return assumption of 7.00% and 6.50%, respectively. Exelon used an EROA of 7.00% and 6.50% to estimate
its 2024 pension and OPEB costs, respectively.

Exelon’s pension and OPEB plan target asset allocations as of December 31, 2023 and 2022 were as follows:

Concentrations of Credit Risk. Exelon evaluated its pension and OPEB plans’ asset portfolios for the existence of significant concentrations of credit risk as of December 31, 2023. Types of concentrations
that were evaluated include, but are not limited to, investment concentrations in a single entity, type of industry, foreign country, and individual fund. As of December 31, 2023, there were no significant
concentrations (defined as greater than 10% of plan assets) of risk in Exelon’s pension and OPEB plan assets.

(b)

Includes  derivative  instruments  of  $51  million  and  $11  million  for  the  years  ended  December  31,  2023  and  2022,  respectively,  which  have  total  notional  amounts  of  $3,351  million  and  $3,434  million  as  of
December 31, 2023 and 2022, respectively. The notional principal amounts for these instruments provide one measure of the transaction volume outstanding as of the fiscal years ended and do not represent the
amount of Exelon's exposure to credit or market loss.

(c) Excludes  net  liabilities  of  $388  million  and  $318  million  as  of  December  31,  2023  and  2022,  respectively,  which  include  certain  derivative  assets  that  have  notional  amounts  of  $59  million  and  $69  million  as  of
December 31, 2023 and 2022, respectively. These items are required to reconcile to the fair value of net plan assets and consist primarily of receivables or payables related to pending securities sales and purchases,
interest and dividends receivable, and repurchase agreement obligations. The repurchase agreements generally have maturities ranging from 3 - 6 months.

The following table presents the reconciliation of Level 3 assets and liabilities for Exelon measured at fair value for pension and OPEB plans for the years ended December 31, 2023 and 2022:

Valuation Techniques Used to Determine Fair Value

The techniques used to fair value the pension and OPEB assets invested in cash equivalents are the same as the valuation techniques used to determine the fair value of financial assets. See Cash
Equivalents  in  Note  17  -  Fair  Value  of  Financial Assets  and  Liabilities  for  further  information.  Below  outlines  the  techniques  used  to  fair  value  the  pension  and  OPEB  assets  invested  in  equities,  fixed
income, derivatives, private credit, private equity, and real estate investments.

Equities.  These  investments  consist  of  individually  held  equity  securities,  equity  mutual  funds,  and  equity  commingled  funds  in  domestic  and  foreign  markets.  With  respect  to  individually  held  equity
securities, the trustees obtain prices from pricing services, whose prices are generally obtained from direct feeds from market

228

(Dollars in millions, except per share data unless otherwise noted)

Note 14 — Retirement Benefits

exchanges,  which  Exelon  is  able  to  independently  corroborate.  Equity  securities  held  individually,  including  real  estate  investment  trusts,  rights,  and  warrants,  are  primarily  traded  on  exchanges  that
contain only actively traded securities due to the volume trading requirements imposed by these exchanges. The equity securities that are held directly by the trust funds are valued based on quoted prices
in active markets and categorized as Level 1. Certain equity securities have been categorized as Level 2 because they are based on evaluated prices that reflect observable market information, such as
actual  trade  information  or  similar  securities.  Certain  private  placement  equity  securities  are  categorized  as  Level  3  because  they  are  not  publicly  traded  and  are  priced  using  significant  unobservable
inputs.

Equity commingled funds and mutual funds are maintained by investment companies, and fund investments are held in accordance with a stated set of fund objectives. The values of some of these funds
are publicly quoted. For mutual funds which are publicly quoted, the funds are valued based on quoted prices in active markets and have been categorized as Level 1. For equity commingled funds and
mutual funds that are not publicly quoted, the fund administrators value the funds using the NAV per fund share, derived from the quoted prices in active markets on the underlying securities and are not
classified within the fair value hierarchy. These investments can typically be redeemed monthly or more frequently, with 30 or less days of notice and without further restrictions.

Fixed income. For fixed income securities, which consist primarily of corporate debt securities, U.S. government securities, foreign government securities, municipal bonds, asset and mortgage-backed
securities, commingled funds, mutual funds, and derivative instruments, the trustees obtain multiple prices from pricing vendors whenever possible, which enables cross-provider validations in addition to
checks for unusual daily movements. A primary price source is identified based on asset type, class, or issue for each security. With respect to individually held fixed income securities, the trustees monitor
prices supplied by pricing services and may use a supplemental price source or change the primary price source of a given security if the portfolio managers challenge an assigned price and the trustees
determine another price source is considered to be preferable. Exelon has obtained an understanding of how these prices are derived, including the nature and observability of the inputs used in deriving
such prices. Additionally, Exelon selectively corroborates the fair values of securities by comparison to other market-based price sources. Investments in U.S. Treasury securities have been categorized as
Level 1 because they trade in highly-liquid and transparent markets. Certain private placement fixed income securities have been categorized as Level 3 because they are priced using certain significant
unobservable  inputs  and  are  typically  illiquid.  The  remaining  fixed  income  securities,  including  certain  other  fixed  income  investments,  are  based  on  evaluated  prices  that  reflect  observable  market
information, such as actual trade information of similar securities, adjusted for observable differences and are categorized as Level 2.

Other fixed income investments primarily consist of fixed income commingled funds and mutual funds, which are maintained by investment companies and hold fund investments in accordance with a
stated set of fund objectives. The values of some of these funds are publicly quoted. For mutual funds which are publicly quoted, the funds are valued based on quoted prices in active markets and have
been categorized as Level 1. For fixed income commingled funds and mutual funds that are not publicly quoted, the fund administrators value the funds using the NAV per fund share, derived from the
quoted prices in active markets of the underlying securities and are not classified within the fair value hierarchy. These investments typically can be redeemed monthly or more frequently, with 30 or less
days of notice and without further restrictions.

Derivative instruments. These instruments, consisting primarily of futures and swaps to manage risk, are recorded at fair value. Over-the-counter derivatives are valued daily, based on quoted prices in
active markets and trade in open markets, and have been categorized as Level 1. Derivative instruments other than over-the-counter derivatives are valued based on external price data of comparable
securities and have been categorized as Level 2.

Private credit.  Private  credit  investments  primarily  consist  of  investments  in  private  debt  strategies.  These  investments  are  generally  less  liquid  assets  with  an  underlying  term  of  3  to  5  years  and  are
intended to be held to maturity. The fair value of these investments is determined by the fund manager or administrator using a combination of valuation models including cost models, market models, and
income models and typically cannot be redeemed until maturity of the term loan. For managed private credit funds, the fair value is determined using a combination of valuation models including cost
models, market models, and income models and typically cannot be redeemed until maturity of the term loan. Managed private credit fund investments are not classified within the fair value hierarchy
because their fair value is determined using NAV or its equivalent as a practical expedient.

229

(Dollars in millions, except per share data unless otherwise noted)

Note 14 — Retirement Benefits

Private equity.  These  investments  include  those  in  limited  partnerships  that  invest  in  operating  companies  that  are  not  publicly  traded  on  a  stock  exchange  such  as  leveraged  buyouts,  growth  capital,
venture capital, distressed investments, and investments in natural resources. These investments typically cannot be redeemed and are generally liquidated over a period of 8 to 10 years from the initial
investment  date,  which  is  based  on  Exelon's  understanding  of  the  investment  funds.  Private  equity  valuations  are  reported  by  the  fund  manager  and  are  based  on  the  valuation  of  the  underlying
investments, which include unobservable inputs such as cost, operating results, discounted future cash flows, and market based comparable data. These valuation inputs are unobservable. The fair value
of private equity investments is determined using NAV or its equivalent as a practical expedient, and therefore, these investments are not classified within the fair value hierarchy.

Real estate. These investments are funds with a direct investment in pools of real estate properties. These funds are reported by the fund manager and are generally based on independent appraisals of
the  underlying  investments  from  sources  with  professional  qualifications,  typically  using  a  combination  of  market  based  comparable  data  and  discounted  cash  flows.  These  valuation  inputs  are
unobservable. Certain real estate investments cannot be redeemed and are generally liquidated over a period of 8 to 10 years from the initial investment date, which is based on Exelon's understanding of
the investment funds. The remaining liquid real estate investments are generally redeemable from the investment vehicle quarterly, with 30 to 90 days of notice. The fair value of real estate investments is
determined using NAV or its equivalent as a practical expedient, and therefore, these investments are not classified within the fair value hierarchy.

Pension and OPEB assets also include investments in hedge funds. Hedge fund investments include those that employ a broad range of strategies to enhance returns and provide additional diversification.
The fair value of hedge funds is determined using NAV or its equivalent  as  a  practical  expedient,  and  therefore,  hedge  funds  are  not  classified  within  the  fair  value  hierarchy.  Exelon  has  the  ability  to
redeem these investments at NAV or its equivalent subject to certain restrictions that may include a lock-up period or a gate.

Defined Contribution Savings Plan

The Registrants participate in a 401(k) defined contribution savings plan that is sponsored by Exelon. The plan is qualified under applicable sections of the IRC and allows employees to contribute a portion
of  their  pre-tax  and/or  after-tax  income  in  accordance  with  specified  guidelines. All  Registrants  match  a  percentage  of  the  employee  contributions  up  to  certain  limits.  The  following  table  presents  the
employer contributions and employer matching contributions to the savings plan for the years ended December 31, 2023, 2022, and 2021:

15. Derivative Financial Instruments (All Registrants)

The Registrants use derivative instruments  to  manage  commodity  price  risk  and  interest  rate  risk  related  to  ongoing  business  operations.  The  Registrants  do  not  execute  derivatives  for  speculative  or
proprietary trading purposes.

Authoritative guidance requires that derivative instruments be recognized as either assets or liabilities at fair value, with changes in fair value of the derivative recognized in earnings immediately. Other
accounting treatments are available through special election and designation, provided they meet specific, restrictive criteria both at the time of designation and on an ongoing basis. These alternative
permissible  accounting  treatments  include  NPNS,  cash  flow  hedges,  and  fair  value  hedges. At  ComEd,  derivative  economic  hedges  related  to  commodities  are  recorded  at  fair  value  and  offset  by  a
corresponding  regulatory  asset  or  liability. At  Exelon,  derivative  economic  hedges  related  to  interest  rates  are  recorded  at  fair  value  and  offsets  are  recorded  to  Electric  operating  revenues  or  Interest
expense based on the activity the transaction is economically hedging. For all NPNS derivative instruments, accounts receivable or accounts payable are recorded when derivatives settle and revenue or
expense is recognized in earnings as the underlying physical commodity is sold or consumed. At Exelon, derivative hedges that qualify and are designated as cash flow hedges are recorded at fair value
and offsets are recorded to AOCI.

Note 15 — Derivative Financial Instruments

ComEd’s  use  of  cash  collateral  is  generally  unrestricted  unless  ComEd  is  downgraded  below  investment  grade.  Cash  collateral  held  by  PECO,  BGE,  Pepco,  DPL,  and ACE  must  be  deposited  in  an
unaffiliated major U.S. commercial bank or foreign bank with a U.S. branch office that meets certain qualifications.

Commodity Price Risk

The Utility Registrants employ established policies and procedures to manage their risks associated with market fluctuations in commodity prices by entering into physical and financial derivative contracts,
which are either determined to be non-derivative or classified as economic hedges. The Utility Registrants procure electric and natural gas supply through a competitive procurement process approved by
each of the respective state utility commissions. The Utility Registrants’ hedging programs are intended to reduce exposure to energy and natural gas price volatility and have no direct earnings impact as
the costs are fully recovered from customers through regulatory-approved recovery mechanisms. The following table provides a summary of the Utility Registrants’ primary derivative hedging instruments,
listed by commodity and accounting treatment.

The fair value of derivative economic hedges is presented in Other current assets and current and noncurrent Mark-to-market derivative liabilities in Exelon's and ComEd's Consolidated Balance Sheets.

Interest Rate and Other Risk (Exelon)

Exelon Corporate uses a combination of fixed-rate and variable-rate debt to manage interest rate exposure. Exelon Corporate may utilize interest rate derivatives to lock in rate levels in anticipation of
future  financings,  which  are  typically  designated  as  cash  flow  hedges.  In  addition,  Exelon  Corporate  utilized  interest  rate  swaps  to  manage  interest  rate  exposure  and  manage  potential  fluctuations  in
Electric operating revenues at the corporate level in consolidation, which were directly correlated to yields on U.S. Treasury bonds under ComEd's distribution formula rate through December 31, 2023.
These interest rate swaps were accounted for as economic hedges. A hypothetical 50 basis point change in the interest rates associated with Exelon's interest rate swaps as of December 31, 2023 would
result in an immaterial impact to Exelon's Consolidated Net Income.

For  derivative  instruments  that  qualify  and  are  designated  as  cash  flow  hedges,  the  changes  in  fair  value  each  period  are  initially  recorded  in AOCI  and  reclassified  into  earnings  when  the  underlying
transaction affects earnings. In January 2023, Exelon Corporate entered into $115 million notional of 5-year maturity floating-to-fixed swaps and $115 million notional of 10-year maturity floating-to-fixed
swaps, for a total of $230 million designated as cash flow hedges. In February 2023, Exelon terminated the previously issued floating-to-fixed swaps with a total notional of $1.5 billion upon issuance of
$2.5  billion  of  debt.  See  Note  16  –  Debt  and  Credit Agreements  for  additional  information  on  the  debt  issuance.  Prior  to  the  termination,  the AOCI  derivative  gain  was  $7  million  (net  of  tax).  The
settlements resulted in a cash receipt of $10 million, which is being amortized into Interest expense in Exelon's Consolidated Statement of Operations and Comprehensive Income over the 5-year and 10-
year terms of the swaps.

Since the termination in February 2023, Exelon has entered into additional floating-to-fixed swaps.

The following table provides the notional amounts outstanding held by Exelon at December 31, 2023 and 2022.

Note 15 — Derivative Financial Instruments

Exelon Corporate executes derivative instruments to mitigate exposure to fluctuations in interest rates but for which the fair value or cash flow hedge elections were not made. For derivatives intended to
serve as economic hedges, fair value is recorded on the balance sheet and changes in fair value each period are recognized in earnings or as a regulatory asset or liability, if regulatory requirements are
met, each period.

Exelon Corporate enters into floating-to-fixed interest rate cap swaps to manage a portion of interest rate exposure in connection with existing borrowings. In 2022, Exelon Corporate entered into $1 billion
notional of 18-month maturity floating-to-fixed interest rate cap swaps and $850 million notional of 6-month maturity floating-to-fixed interest rate cap swaps, for a total of $1,850 million notional of floating-
to-fixed interest rate cap swaps as of December 31, 2022. The 6-month maturity floating-to-fixed interest rate cap swaps of $850 million notional matured in March 2023. Exelon receives payments on the
interest rate cap when the floating rate exceeds the fixed rate. Settlements received are immaterial as of December 31, 2023.

Additionally, to manage potential fluctuations in Electric operating revenues related to ComEd's distribution formula rate, Exelon Corporate entered into a total of $4,875 million notional of 30-year constant
maturity treasury interest rate (Corporate 30-year treasury) swaps from 2022 through 2023. The Corporate 30-year treasury swaps matured on December 31, 2023 and Exelon recorded a Mark-to-market
liability of $22 million for the final settlement amount, which was paid in January 2024.

The following table provides the notional amounts outstanding held by Exelon at December 31, 2023 and 2022.

The  Registrants  would  be  exposed  to  credit-related  losses  in  the  event  of  non-performance  by  counterparties  on  executed  derivative  instruments.  The  credit  exposure  of  derivative  contracts,  before
collateral, is represented by the fair value of contracts at the reporting date. The Utility Registrants have contracts to procure electric and natural gas supply that provide suppliers with a certain amount of
unsecured credit. If the exposure on the supply contract exceeds the amount of unsecured credit, the suppliers may be required to post collateral. The net credit exposure is mitigated primarily by the
ability to recover procurement costs through customer rates. The amount of cash collateral received from external counterparties decreased as of December 31, 2023 due to decreasing energy prices. The
following table reflects the Registrants' cash collateral held from external counterparties, which is recorded in Other current liabilities on their respective Consolidated Balance Sheets, at December 31,
2023 and 2022

(a) PECO had less than one million in cash collateral held with external parties as of December 31, 2023 and 2022.

The Utility Registrants’ electric supply procurement contracts do not contain provisions that would require them to post collateral. PECO’s, BGE’s, and DPL’s natural gas procurement contracts contain
provisions that could require PECO, BGE, and DPL to post collateral in the form of cash or credit support, which vary by contract and counterparty, with thresholds contingent upon PECO’s, BGE's, and
DPL’s credit rating. As of December 31, 2023, PECO, BGE, and DPL were not required to post collateral for any of these agreements. If PECO, BGE, or DPL lost their investment grade credit rating as of
December 31, 2023, they could have been required to post collateral to their counterparties of $25 million, $61 million, and $10 million, respectively.

16. Debt and Credit Agreements (All Registrants)

Short-Term Borrowings

Exelon Corporate, ComEd, and BGE meet their short-term liquidity requirements primarily through the issuance of commercial paper. PECO meets its short-term liquidity requirements primarily through the
issuance of commercial paper and borrowings from the Exelon intercompany money pool. Pepco, DPL, and ACE meet their short-term liquidity requirements primarily through the issuance of commercial
paper and borrowings from the PHI intercompany money pool. PHI Corporate meets its short-term liquidity requirements primarily through the issuance of short-term notes and borrowings from the Exelon
intercompany money pool. The Registrants may use their respective credit facilities for general corporate purposes, including meeting short-term funding requirements and the issuance of letters of credit.

__________
(a) Excludes credit facility agreements arranged at minority and community banks. See below for additional information.
(b)

Includes revolving credit agreements at Exelon Corporate with a maximum program size of $900 million as of December 31, 2023 and December 31, 2022. Exelon Corporate had $527 million in outstanding commercial
paper as of December 31, 2023 and $449 million outstanding commercial paper as of December 31, 2022.

(c) Represents the consolidated amounts of Pepco, DPL, and ACE.
(d) The standard maximum program size for revolving credit facilities is $300 million each for Pepco, DPL and ACE based on the credit agreements in place. However, the facilities at Pepco, DPL, and ACE have the ability
to flex to $500 million, $500 million, and $350 million, respectively. The borrowing capacity may be increased or decreased during the term of the facility, except that (i) the sum of the borrowing capacity must equal the
total amount of the facility, and (ii) the aggregate amount of credit used at any given time by each of Pepco, DPL, or ACE may not exceed $900 million or the maximum amount of short-term debt the  company  is
permitted  to  have  outstanding  by  its  regulatory  authorities.  The  total  number  of  the  borrowing  reallocations  may  not  exceed  eight  per  year  during  the  term  of  the  facility.  In  January  2024,  this  ability  was  utilized  to
increase ACE's program size to $350 million. As a result, the program size for Pepco did not change and DPL was decreased to $250 million, which prevents the aggregate amount of outstanding short-term debt from
exceeding the $900 million limit.

In order to maintain their respective commercial paper programs in the amounts indicated above, each Registrant must have credit facilities in place, at least equal to the amount of its commercial paper
program. A registrant does not issue commercial paper in an aggregate amount exceeding the then available capacity under its credit facility.

(a)

Includes interest rate adders at Exelon Corporate of 27.5 basis points and 127.5 basis points for prime and SOFR-based borrowings, respectively.

If any registrant loses its investment grade rating, the maximum adders for prime rate borrowings and SOFR-based rate borrowings would be 65 basis points and 165 basis points, respectively. The credit
agreements also require the borrower to pay a facility fee based upon the aggregate commitments. The fee varies depending upon the respective credit ratings of the borrower. Exelon Corporate and the
Utility Registrants had no outstanding amounts on the revolving credit facilities as of December 31, 2023.

Short-Term Loan Agreements

On  March  23,  2017,  Exelon  Corporate  entered  into  a  term  loan  agreement  for  $500  million.  The  loan  agreement  was  renewed  in  the  first  quarter  of  2023  and  was  bifurcated  into  two  tranches  of
$300  million  on  March  14,  2023  and  $200  million  on  March  24,  2023.  The  agreements  will  expire  on  March  14,  2024  and  March  22,  2024,  respectively.  Pursuant  to  the  loan  agreements,  loans  made
thereunder bear interest at a variable rate equal to SOFR plus 0.90% and all indebtedness thereunder is unsecured. The loan agreement is reflected in Exelon's Consolidated Balance Sheets within Short-
term borrowings.

On October 4, 2022, ComEd entered into a 364-day term loan agreement for $150 million with a variable rate equal to SOFR plus 0.75% and an expiration date of October 3, 2023. The proceeds from this
loan were used to repay outstanding commercial paper obligations. The loan agreement is reflected in Exelon's and ComEd's Consolidated Balance Sheets within Short-term borrowings. The balance of
the loan was repaid on January 13, 2023 in conjunction with the $400 million and $575 million First Mortgage Bond agreements that were entered into on January 3, 2023.

On May 9, 2023, ComEd entered into a 364-day term loan agreement for $400 million with a variable rate equal to SOFR plus 1.00% and an expiration date of May 7, 2024. The proceeds from this loan
were used to repay outstanding commercial paper obligations and for general corporate purposes. The loan agreement is reflected in Exelon's and ComEd's Consolidated Balance Sheets within Short-term
borrowings.

Variable Rate Demand Bonds

DPL has outstanding obligations in respect of Variable Rate Demand Bonds (VRDB). VRDBs are subject to repayment on the demand of the holders and, for this reason, are accounted for as short-term
debt in accordance with GAAP. However, these bonds may be converted to a fixed-rate, fixed-term option to establish a maturity which corresponds to the date of final maturity of the bonds. On this basis,
PHI views VRDBs as a source of long-term financing. At both December 31, 2023 and December 31, 2022, $79 million in variable rate demand bonds issued by DPL were outstanding and are included in
the Long-term debt due within one year in Exelon's, PHI's, and DPL's Consolidated Balance Sheets.

Long-Term Debt to Affiliates

In connection with the debt obligations assumed by Exelon as part of the Constellation merger, Exelon and subsidiaries of Generation (former Constellation subsidiaries) entered into intercompany loan
agreements  that  mirror  the  terms  and  amounts  of  the  third-party  debt  obligations  of  Exelon,  resulting  in  intercompany  notes  receivable  at  Exelon  Corporate  from  Generation.  In  connection  with  the
separation, on January 31, 2022, Exelon Corporate received cash from Generation of $258 million to settle the intercompany loan.

Debt Covenants

As of December 31, 2023, the Registrants are in compliance with debt covenants.

17. Fair Value of Financial Assets and Liabilities (All Registrants)

Exelon measures and classifies fair value measurements in accordance with the hierarchy as defined by GAAP. The hierarchy prioritizes the inputs to valuation techniques used to measure fair value into
three levels as follows:

•

•

Level 1 — quoted prices (unadjusted) in active markets for identical assets or liabilities that the Registrants have the ability to liquidate as of the reporting date.

Level 2 — inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market
data.

242

 
Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 17 — Fair Value of Financial Assets and Liabilities

•

Level 3 — unobservable inputs, such as internally developed pricing models or third-party valuations for the asset or liability due to little or no market activity for the asset or liability.

Fair Value of Financial Liabilities Recorded at Amortized Cost

The  following  tables  present  the  carrying  amounts  and  fair  values  of  the  Registrants’  short-term  liabilities,  long-term  debt,  and  trust  preferred  securities  (long-term  debt  to  financing  trusts  or  junior
subordinated debentures) at December 31, 2023 and 2022. The Registrants have no financial liabilities classified as Level 1 or measured using the NAV practical expedient.

Note 17 — Fair Value of Financial Assets and Liabilities

Exelon uses the following methods and assumptions to estimate fair value of financial liabilities recorded at carrying cost:

Type
Long-Term Debt, including amounts due within one year

Level

Registrants

Valuation

Taxable Debt Securities

Variable Rate Financing Debt

Non-Government Backed Fixed Rate
Nonrecourse Debt

Taxable Private Placement Debt Securities

Long-Term Debt to Financing Trusts

Long Term Debt to Financing Trusts

Recurring Fair Value Measurements

All

The fair value is determined by a valuation model that is based on a conventional discounted cash flow methodology
and  utilizes  assumptions  of  current  market  pricing  curves.  Exelon  obtains  credit  spreads  based  on  trades  of  existing
Exelon  debt  securities  as  well  as  other  issuers  in  the  utility  sector  with  similar  credit  ratings.  The  yields  are  then
converted into discount rates of various tenors that are used for discounting the respective cash flows of the same tenor
for each bond or note.

Exelon, DPL

Debt rates are reset on a regular basis and the carrying value approximates fair value.

Exelon

Fair value is based on market and quoted prices for its own and other nonrecourse debt with similar risk profiles. Given
the low trading volume in the nonrecourse debt market, the price quotes used to determine fair value will reflect certain
qualitative factors, such as market conditions, investor demand, new developments that might significantly impact the
project cash flows or off-taker credit, and other circumstances related to the project.

Exelon, Pepco, DPL, ACE

Rates are obtained similar to the process for taxable debt securities. Due to low trading volume and qualitative factors
such as market conditions, low volume of investors, and investor demand, these debt securities are Level 3.

Exelon, ComEd, PECO

Fair  value  is  based  on  publicly  traded  securities  issued  by  the  financing  trusts.  Due  to  low  trading  volume  of  these
securities  and  qualitative  factors,  such  as  market  conditions,  investor  demand,  and  circumstances  related  to  each
issue, this debt is classified as Level 3.

The following tables present assets and liabilities measured and recorded at fair value in the Registrants' Consolidated Balance Sheets on a recurring basis and their level within the fair value hierarchy at
December 31, 2023 and 2022. Exelon and the Utility Registrants have immaterial and no financial assets or liabilities measured using the NAV practical expedient, respectively:

Valuation Techniques Used to Determine Fair Value

Cash Equivalents (All Registrants). Investments with original maturities of three months or less when purchased, including mutual and money market funds, are considered cash equivalents. The fair
values are based on observable market prices and, therefore, are included in the recurring fair value measurements hierarchy as Level 1.

Rabbi Trust Investments (Exelon, PECO, BGE, PHI, Pepco, DPL, and ACE). The Rabbi trusts were established to hold assets related to deferred compensation plans existing for certain active and
retired members of Exelon’s executive management and directors. The Rabbi trusts' assets are included in Investments in the Registrants’ Consolidated Balance Sheets and consist primarily of money
market  funds,  mutual  funds,  fixed  income  securities,  and  life  insurance  policies.  Money  market  funds  and  mutual  funds  are  publicly  quoted  and  have  been  categorized  as  Level  1  given  the  clear
observability of the prices. The fair values of fixed income securities are based on evaluated prices that reflect observable market information, such as actual trade information or similar securities, adjusted
for observable differences and are categorized in Level 2. The life insurance policies are valued using the cash surrender value of the policies, net of loans against those policies, which is provided by a
third-party. Certain life insurance policies, which consist primarily of mutual funds that are priced based on observable market data, have been categorized as Level 2 because the life insurance policies
can be liquidated at the reporting date for the value of the underlying assets. Life insurance policies that are valued using unobservable inputs have been categorized as Level 3, where the fair value is
determined based on the cash surrender value of the policy, which contains unobservable inputs and assumptions. Because Exelon relies on its third-party insurance provider to develop the inputs without
adjustment for the valuations of its Level 3 investments, quantitative information about significant unobservable inputs used in valuing these investments is not reasonably available to Exelon. Therefore,
Exelon has not disclosed such inputs.

Interest Rate Derivatives (Exelon) Exelon may utilize fixed-to-floating or floating-to-fixed interest rate swaps as a means to manage interest rate risk. These interest rate swaps are typically accounted for
as economic hedges. In addition, Exelon may utilize interest rate derivatives to lock in interest rate levels in anticipation of future financings. These interest rate derivatives are typically designated as cash
flow  hedges.  Exelon  determines  the  current  fair  value  by  calculating  the  net  present  value  of  expected  payments  and  receipts  under  the  swap  agreement,  based  on  and  discounted  by  the  market's
expectation of future interest rates. Additional inputs to the net present value calculation may include the contract terms, counterparty credit risk and other market parameters. As these inputs are based on
observable  data  and  valuations  of  similar  instruments,  the  interest  rate  swaps  are  categorized  as  Level  2  in  the  fair  value  hierarchy.  See  Note  15  —  Derivative  Financial  Instruments   for  additional
information on mark-to-market derivatives.

Note 17 — Fair Value of Financial Assets and Liabilities

Deferred  Compensation  Obligations  (All  Registrants).   The  Registrants’  deferred  compensation  plans  allow  participants  to  defer  certain  cash  compensation  into  a  notional  investment  account.  The
Registrants include such plans in  other  current  and  noncurrent  liabilities  in  their  Consolidated  Balance  Sheets.  The  value  of  the  Registrants’  deferred  compensation  obligations  is  based  on  the  market
value of the participants’ notional investment accounts. The underlying notional investments are comprised primarily of equities, mutual funds, commingled funds, and fixed income securities which are
based on directly and indirectly observable market prices. Since the deferred compensation obligations themselves are not exchanged in an active market, they are categorized as Level 2 in the fair value
hierarchy.

The value of certain employment agreement obligations (which are included with the Deferred Compensation Obligation in the tables above) are based on a known and certain stream of payments to be
made over time and are categorized as Level 2 within the fair value hierarchy.

Commodity Derivatives (Exelon and ComEd). On December 17, 2010, ComEd entered into several 20-year floating to fixed energy swap contracts with unaffiliated suppliers for the procurement of long-
term renewable energy and associated RECs. Delivery under the contracts began in June 2012. The fair value of these swaps has been designated as a Level 3 valuation due to the long tenure of the
positions and the internal modeling assumptions. The modeling assumptions include using forward power prices. See Note 15 — Derivative Financial Instruments for additional information on mark-to-
market derivatives.

__________
(a) Exelon and certain of its subsidiaries maintain non-debt letters of credit to provide credit support for certain transactions as requested by third parties.
(b) Surety bonds—Guarantees issued related to contract and commercial agreements, excluding bid bonds. Historically, payments under the guarantees have not been made and the likelihood of payments being required

is remote.

(c) Reflects guarantee of ComEd and PECO securities held by ComEd Financing III, PECO Trust III, and PECO Trust IV.
(d) Represents the maximum potential obligation in the event that the fair value of certain leased equipment and fleet vehicles is zero at the end of the maximum lease term. The lease term associated with these assets
ranges from 1 to 8 years. The maximum potential obligation at the end of the minimum lease term would be $61 million guaranteed by Exelon and PHI, of which $20 million, $24 million, and $17 million is guaranteed by
Pepco, DPL, and ACE, respectively. Historically, payments under the guarantees have not been made and PHI believes the likelihood of payments being required under the guarantees is remote.

Environmental Remediation Matters

General (All Registrants). The Registrants’ operations have in the past, and may in the future, require substantial expenditures to comply with environmental laws. Additionally, under federal and state
environmental laws, the Registrants are generally liable for the costs of remediating environmental contamination of property now or formerly owned by them and of property contaminated by hazardous
substances generated by them. The Registrants own or lease a number of real estate parcels, including parcels on which their operations or the operations of others may have resulted in contamination by
substances that are considered hazardous under environmental laws. In addition, the Registrants are currently involved in a number of proceedings relating to sites where hazardous substances have
been deposited and may be subject to additional proceedings in the future. Unless otherwise disclosed, the Registrants cannot reasonably estimate whether they will incur significant liabilities for additional
investigation  and  remediation  costs  at  these  or  additional  sites  identified  by  the  Registrants,  environmental  agencies  or  others,  or  whether  such  costs  will  be  recoverable  from  third  parties,  including
customers. Additional costs could have a material, unfavorable impact on the Registrants' financial statements.

MGP Sites (All Registrants). ComEd, PECO, BGE, and DPL have identified sites where former MGP or gas purification activities have or may have resulted in actual site contamination. For some sites,
there are additional PRPs that may share responsibility for the ultimate remediation of each location.

•

•

•

•

ComEd has 17 sites that are currently under some degree of active study and/or remediation. ComEd expects the majority of the remediation at these sites to continue through at least 2031.

PECO has 6 sites that are currently under some degree of active study and/or remediation. PECO expects the majority of the remediation at these sites to continue through at least 2025.

BGE has 4 sites that currently require some level of remediation and/or ongoing activity. BGE expects the majority of the remediation at these sites to continue through at least 2025.

DPL has 1 site that is currently under study and the required cost at the site is not expected to be material.

The historical nature of the MGP and gas purification sites and the fact that many of the sites have been buried and built over, impacts the ability to determine a precise estimate of the ultimate costs prior
to initial sampling and determination of the exact scope and method of remedial activity. Management determines its best estimate of remediation costs using all available information at the time of each
study, including probabilistic and deterministic modeling for ComEd and PECO, and the remediation standards currently required by the applicable state environmental agency. Prior to completion of any
significant clean up, each site remediation plan is approved by the appropriate state environmental agency.

ComEd, pursuant to an ICC order, and PECO, pursuant to a PAPUC order, are currently recovering environmental remediation costs of former MGP facility sites through customer rates. While BGE and
DPL do not have riders for MGP clean-up costs, they have historically received recovery of actual clean-up costs in distribution rates.

In  2023,  ComEd  and  PECO  completed  an  annual  study  of  their  future  estimated  MGP  remediation  requirements.  The  study  resulted  in  a  $25  million  increase  to  the  environmental  liability  and  related
regulatory asset for ComEd.

Note 18 — Commitments and Contingencies

The increase was primarily due to increased costs resulting from inflation and changes in remediation plans. The study did not result in a material change to the environmental liability for PECO.

At December 31, 2023 and 2022, the Registrants had accrued the following undiscounted amounts for environmental liabilities in Accrued expenses, Other current liabilities, and Other deferred credits and
other liabilities in their respective Consolidated Balance Sheets:

Benning Road Site (Exelon, PHI, and Pepco). In September 2010, PHI received a letter from EPA identifying the Benning Road site as one of six land-based sites potentially contributing to contamination
of the lower Anacostia River. A portion of the site, which is owned by Pepco, was formerly the location of an electric generating facility owned by Pepco subsidiary, Pepco Energy Services (PES), which
became a part of Generation, following the 2016 merger between PHI and Exelon. This generating facility was deactivated in June 2012. The remaining portion of the site consists of a Pepco transmission
and  distribution  service  center  that  remains  in  operation.  In  December  2011,  the  U.S.  District  Court  for  the  District  of  Columbia  approved  a  Consent  Decree  entered  into  by  Pepco  and  Pepco  Energy
Services (hereinafter "Pepco Entities") with the DOEE, which requires the Pepco Entities to conduct a Remedial Investigation and Feasibility Study (RI/FS) for the Benning Road site and an approximately
10 to 15-acre portion of the adjacent Anacostia River. The purpose of this RI/FS is to define the nature and extent of contamination from the Benning Road site and to evaluate remedial alternatives.

Pursuant to an internal agreement between the Pepco Entities, since 2013, Pepco has performed the work required by the Consent Decree and has been reimbursed for that work by an agreed upon
allocation of costs between the Pepco Entities. In September 2019, the Pepco Entities issued a draft “final” RI report which DOEE approved on February 3, 2020. The Pepco Entities are completing a FS to
evaluate possible remedial alternatives for submission to DOEE. In October, 2022, DOEE approved dividing the work to complete the landside portion of the FS from the waterside portion to expedite the
overall schedule for completion of the project. It is currently anticipated that the landside FS will be complete and approved by DOEE by the end of the first quarter of 2024 and the waterside FS will be
complete and approved by DOEE by the end of the fourth quarter of 2024. Following the completion of each FS, DOEE will issue a Proposed Plan for public comment and then issue a Record of Decision
(ROD) identifying the remedial actions determined to be necessary for the area in question. On October 3, 2023, DOEE and Pepco entered into an addendum to the Benning Consent Decree pursuant to
which Pepco has agreed to fund or perform the remedial actions to be selected by DOEE for the landslide and water areas. This addendum to the Benning Consent Decree has been lodged with the court
in January 2024. Once the addendum is signed and entered by the court it will become effective.

As part of the separation between Exelon and Constellation in February 2022, the internal agreement between the Pepco Entities for completion and payment for the remaining Consent Decree work was
memorialized  in  a  formal  agreement  for  post-separation  activities.  A  second  post-separation  assumption  agreement  between  Exelon  and  Constellation  transferred  any  of  the  potential  remaining
remediation  liability,  if  any,  of  PES/Generation  to  a  non-utility  subsidiary  of  Exelon  which  going  forward  will  be  responsible  for  those  liabilities.  Exelon,  PHI,  and  Pepco  have  determined  that  a  loss
associated with this matter is probable and have accrued an estimated liability, which is included in the table above.

Anacostia River Tidal Reach (Exelon, PHI, and Pepco). Contemporaneous with the Benning Road site RI/FS being performed by the Pepco Entities, DOEE and NPS have been conducting a separate
RI/FS focused on the

252

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 18 — Commitments and Contingencies

entire tidal reach of the Anacostia River extending from just north of the Maryland-District of Columbia boundary line to the confluence of the Anacostia and Potomac Rivers. The river-wide RI incorporated
the results of the river sampling performed by the Pepco Entities as part of the Benning RI/FS, as well as similar sampling efforts conducted by owners of other sites adjacent to this segment of the river
and supplemental river sampling conducted by DOEE’s contractor.

On September 30, 2020, DOEE released its Interim ROD for the Anacostia River sediments. The Interim ROD reflects an adaptive management approach which will require several identified “hot spots” in
the river to be addressed first while continuing to conduct studies and to monitor the river to evaluate improvements and determine potential future remediation plans. The adaptive management process
chosen by DOEE is less intrusive, provides more long-term environmental certainty, is less costly, and allows for site specific remediation plans already underway, including the plan for the Benning Road
site to proceed to conclusion.

On July 15, 2022, Pepco received a letter from the District of Columbia's Office of the Attorney General (D.C. OAG) on behalf of DOEE conveying a settlement offer to resolve all PRPs' liability to the
District of Columbia (District) for their past costs and their anticipated future costs to complete the work for the Interim ROD. Pepco responded on July 27, 2022 to enter into settlement discussions. On
October 3, 2023, Pepco and the District entered into another consent decree (the “Anacostia River Consent Decree”) pursuant to which Pepco agreed to pay $47 million to resolve its liability to the District
for all past costs to perform the river-wide RI/FS and all future costs to complete the work required by the Interim ROD. This amount will be paid in four equal annual installments beginning a year after the
effective date of the Anacostia River Consent Decree. The funds will be deposited into the DOEE’s Clean Land Fund for the District’s costs of the Interim ROD work.  The Anacostia River Consent Decree
caps Pepco’s liability for these costs and provides Pepco with the right to seek contribution from other potentially responsible parties. The Anacostia River Consent Decree was lodged with the U.S. District
Court for the District of Columbia in January 2024. Once the court signs and approves the Anacostia River Consent Decree it will become effective. Exelon, PHI, and Pepco have accrued a liability for
Pepco’s payment obligations under the Anacostia Consent Decree and management's best estimate of its share of any other future Anacostia River response costs. Pepco has concluded that incremental
exposure remains reasonably possible, but management cannot reasonably estimate a range of loss beyond the amounts recorded, which are included in the table above.

In addition to the activities associated with the remedial process outlined above, CERCLA separately requires federal and state (here including Washington, D.C.) Natural Resource Trustees (federal or
state agencies designated by the President or the relevant state, respectively, or Indian tribes) to conduct an assessment of any damages to natural resources within their jurisdiction as a result of the
contamination that is being remediated. The Trustees can seek compensation from responsible parties for such damages, including restoration costs. During the second quarter of 2018, Pepco became
aware that the Trustees are in the beginning stages of a NRD assessment, a process that often takes many years beyond the remedial decision to complete. Pepco has concluded that a loss associated
with the eventual NRD assessment is reasonably possible. Due to the very early stage of the NRD process, Pepco cannot reasonably estimate the final range of loss potentially resulting from this process.

As  noted  in  the  Benning  Road  Site  disclosure  above,  as  part  of  the  separation  of  Exelon  and  Constellation  in  February  2022,  an  assumption  agreement  was  executed  transferring  any  potential  future
remediation liabilities associated with the Benning Site remediation to a non-utility subsidiary of Exelon. Similarly, any potential future liability associated with the Anacostia River Sediment Project (ARSP)
was also assumed by this entity.

Buzzard Point Site (Exelon, PHI, and Pepco). On December 8, 2022, Pepco received a letter from the D.C. OAG, alleging wholly past violations of the District's stormwater discharge and waste disposal
requirements related to operations at the Buzzard Point facility, a 9-acre parcel of waterfront property in Washington, D.C. occupied by an active substation and former steam plant building. The letter also
alleged wholly past violations by Pepco of stormwater discharge requirements related to its district-wide system of underground vaults. On October 3, 2023, Pepco entered into a Consent Order with the
District of Columbia to resolve the alleged violations without any admission of liability. The Consent Order requires Pepco to pay a civil penalty of $10 million. In addition, Pepco has agreed to assess the
environmental conditions at its Buzzard Point facility and conduct any remedial actions deemed necessary as a result of the assessment, and also to assess potential environmental impacts associated
with the operation of its underground vaults. The Consent Order was lodged with the District of Columbia Superior Court in January 2024. The court signed and entered the Consent Order, and it became
effective on February 2, 2024. Exelon, PHI, and Pepco have accrued a liability for the penalty

253

Note 18 — Commitments and Contingencies

payments and for the projected costs for the required environmental assessments and remediation. Pepco has concluded that incremental exposure is reasonably possible, but the range of loss cannot be
reasonably estimated beyond the amounts included in the table above.

Litigation and Regulatory Matters

Fund Transfer Restrictions (All Registrants). Under applicable law, Exelon may borrow or receive an extension of credit from its subsidiaries. Under the terms of Exelon’s intercompany money pool
agreement, Exelon can lend to, but not borrow from the money pool.

Under applicable law, ComEd, PECO, BGE, PHI, Pepco, DPL, and ACE can pay dividends only from retained, undistributed or current earnings. A significant loss recorded at ComEd, PECO, BGE, PHI,
Pepco, DPL, or ACE may limit the dividends that these Registrants can distribute to Exelon.

ComEd has agreed in connection with financings arranged through ComEd Financing III that it will not declare dividends on any shares of its capital stock in the event that: (1) it exercises its right to extend
the interest payment periods on the subordinated debt securities issued to ComEd Financing III; (2) it defaults on its guarantee of the payment of distributions on the preferred trust securities of ComEd
Financing III; or (3) an event of default occurs under the Indenture under which the subordinated debt securities are issued. No such event has occurred.

PECO has agreed in connection with financings arranged through PEC L.P. and PECO Trust IV that PECO will not declare dividends on any shares of its capital stock in the event that: (1) it exercises its
right to extend the interest payment periods on the subordinated debentures, which were issued to PEC L.P. or PECO Trust IV; (2) it defaults on its guarantee of the payment of distributions on the Series
D Preferred Securities of PEC L.P. or the preferred trust securities of PECO Trust IV; or (3) an event of default occurs under the Indenture under which the subordinated debentures are issued. No such
event has occurred.

BGE is subject to restrictions established by the MDPSC that prohibit BGE from  paying  a  dividend  on  its  common  shares  if  (a)  after  the  dividend  payment,  BGE’s  equity  ratio  would  be  below  48%  as
calculated pursuant to the MDPSC’s ratemaking precedents or (b) BGE’s senior unsecured credit rating is rated by two of the three major credit rating agencies below investment grade. No such event has
occurred.

Pepco is subject to certain dividend restrictions established by settlements approved by the MDPSC and DCPSC that prohibit Pepco from paying a dividend on its common shares if (a) after the dividend
payment, Pepco's equity ratio would be 48% as calculated pursuant to the MDPSC's and DCPSC's ratemaking precedents, of or (b) Pepco’s senior unsecured credit rating is rated by one of the three
major credit rating agencies below investment grade. No such event has occurred.

DPL is subject to certain dividend restrictions established by settlements approved by the DEPSC and MDPSC that prohibit DPL from paying a dividend on its common shares if (a) after the dividend
payment, DPL's equity ratio would be 48% as calculated pursuant to the DEPSC's and MDPSC's ratemaking precedents, or (b) DPL’s corporate issuer or senior unsecured credit rating, or its equivalent, is
rated by any of the three major credit rating agencies below the generally accepted definition of investment grade. No such event has occurred.

ACE is subject to certain dividend restrictions established by settlements approved by the NJBPU that prohibit ACE from paying a dividend on its common shares if (a) after the dividend payment, ACE's
common equity ratio would be 48% as calculated pursuant to the NJBPU's ratemaking precedents, or (b) ACE's senior corporate issuer or senior unsecured credit rating is rated by one of the three major
credit rating agencies below investment grade. ACE is also subject to a dividend restriction which requires ACE to notify and obtain the prior approval of the NJBPU before dividends can be paid if its equity
as a percent of its total capitalization, excluding securitization debt, falls below 30%. No such events have occurred.

DPA and Related Matters (Exelon and ComEd). Exelon and ComEd received a grand jury subpoena in the second quarter of 2019 from the USAO requiring production of information concerning their
lobbying activities in the State of Illinois. On October 4, 2019, Exelon and ComEd received a second grand jury subpoena from the USAO requiring production of records of any communications with certain
individuals and entities. On October 22, 2019, the SEC notified Exelon and ComEd that it had also opened an investigation into their lobbying activities. On July 17, 2020, ComEd entered into a DPA with
the USAO to resolve the USAO investigation. Under the DPA, the USAO filed a single charge alleging that ComEd improperly gave and offered to give jobs, vendor

254

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 18 — Commitments and Contingencies

subcontracts, and payments associated with those jobs and subcontracts for the benefit of the former Speaker of the Illinois House of Representatives and the Speaker’s associates, with the intent to
influence the Speaker’s action regarding legislation affecting ComEd’s interests. The DPA provided that the USAO would defer any prosecution of such charge and any other criminal or civil case against
ComEd in connection with the matters identified therein for a three-year period subject to certain obligations of ComEd, including payment to the U.S. Treasury of $200 million, which was paid in November
2020. Exelon was not made a party to the DPA, and therefore the investigation by the USAO into Exelon’s activities ended with no charges being brought against Exelon. The three-year term of the DPA
ended on July 17, 2023, and on that same date the court granted the USAO’s motion to dismiss the pending charge against ComEd that had been deferred by the DPA.

On September 28, 2023, Exelon and ComEd reached a settlement with the SEC, concluding and resolving in its entirety the SEC investigation, which related to the conduct identified in the DPA that was
entered into by ComEd in July 2020 and successfully exited in July 2023. Under the terms of the settlement, Exelon agreed to pay a civil penalty of $46.2 million and Exelon and ComEd agreed to cease
and desist from committing or causing any violations and any future violations of specified provisions of the federal securities laws and rules promulgated thereunder. Exelon recorded an accrual for the full
amount of the penalty in the second quarter of 2023, which was reflected in Operating and maintenance expense within Exelon's Consolidated Statements of Operations and Comprehensive Income and in
Accrued expenses on the Consolidated Balance Sheets. Exelon paid the civil penalty in full on October 4, 2023.

Subsequent to Exelon announcing the receipt of the subpoenas, various lawsuits were filed, and various demand letters were received related to the subject of the subpoenas and, the conduct described in
the DPA and the SEC's investigation, including:

Four putative class action lawsuits against ComEd and Exelon were filed in federal court on behalf of ComEd customers in the third quarter of 2020 alleging, among other things, civil violations of
federal racketeering laws. In addition, the Citizens Utility Board (CUB) filed a motion to intervene in these cases on October 22, 2020 which was granted on December 23, 2020. On September 9,
2021, the federal court granted Exelon’s and ComEd’s motion to dismiss and dismissed the plaintiffs’ and CUB’s federal law claim with prejudice. The federal court also dismissed the related state
law claims made by the federal plaintiffs and CUB on jurisdictional grounds. Plaintiffs appealed dismissal of the federal law claim to the Seventh Circuit Court of Appeals. Plaintiffs and CUB also
refiled their state law claims in state court and moved to consolidate them with the already pending consumer state court class action, discussed below. On August 22, 2022, the Seventh Circuit
affirmed the dismissal of the consolidated federal cases in their entirety. The time to further appeal has passed and the Seventh Circuit’s decision is final.

Three putative class action lawsuits against ComEd and Exelon were filed in Illinois state court in the third quarter of 2020 seeking restitution and compensatory damages on behalf of ComEd
customers. The cases were consolidated into a single action in October of 2020. In November 2020, CUB filed a motion to intervene in the cases pursuant to an Illinois statute allowing CUB to
intervene  as  a  party  or  otherwise  participate  on  behalf  of  utility  consumers  in  any  proceeding  which  affects  the  interest  of  utility  consumers.  On  November  23,  2020,  the  court  allowed  CUB’s
intervention, but denied CUB's request to stay these cases. Plaintiffs subsequently filed a consolidated complaint, and ComEd and Exelon filed a motion to dismiss on jurisdictional and substantive
grounds on January 11, 2021. Briefing on that motion was completed on March 2, 2021. The parties agreed, on March 25, 2021, along with the federal court plaintiffs discussed above, to jointly
engage in mediation. The parties participated in a one-day mediation on June 7, 2021 but no settlement was reached. On December 23, 2021, the state court granted ComEd and Exelon’s motion
to  dismiss  with  prejudice.  On  December  30,  2021,  plaintiffs  filed  a  motion  to  reconsider  that  dismissal  and  for  permission  to  amend  their  complaint.  The  court  denied  the  plaintiffs'  motion  on
January 21, 2022. Plaintiffs have appealed the court's ruling dismissing their complaint to the First District Court of Appeals. On February 15, 2022, Exelon and ComEd moved to dismiss the
federal plaintiffs' refiled state law claims, seeking dismissal on the same legal grounds asserted in their motion to dismiss the original state court plaintiffs' complaint. The court granted dismissal
of the refiled state claims on February 16, 2022. The original federal plaintiffs appealed that dismissal on February 18, 2022. The two state appeals were consolidated on March 21, 2022. On
September 8, 2023, the Illinois appellate court affirmed the dismissal. Plaintiffs have asked the Illinois Supreme Court to grant them leave to further appeal, but such appeal is not allowed as a
matter of right.

On November 3, 2022, a plaintiff filed a putative class action complaint in Lake County, Illinois Circuit Court against ComEd and Exelon for unjust enrichment and deceptive business practices in
connection with the conduct giving rise to the DPA. Plaintiff seeks an accounting and disgorgement of any benefits ComEd allegedly obtained from said conduct. Plaintiff served initial discovery
requests on ComEd in December 2022, to which ComEd has responded. ComEd and Exelon filed a motion to dismiss the Complaint on February 3, 2023. On June 16, 2023, the court granted
Exelon and ComEd's motion to dismiss the action with prejudice. Plaintiff filed its notice of appeal of that dismissal on July 17, 2023. Plaintiff's opening appellate brief was filed on October 19,
2023. ComEd and Exelon filed a response on January 2, 2024. Plaintiff filed its reply brief on February 2, 2024. With leave of court, Exelon and ComEd filed a sur-reply on February 14, 2024. The
appellate court has set oral argument for April 3, 2024.

A putative class action lawsuit against Exelon and certain officers of Exelon and ComEd was filed in federal court in December 2019 alleging misrepresentations and omissions in Exelon’s SEC
filings  related  to  ComEd’s  lobbying  activities  and  the  related  investigations.  The  complaint  was  amended  on  September  16,  2020,  to  dismiss  two  of  the  original  defendants  and  add  other
defendants, including ComEd. Defendants filed a motion to dismiss in November 2020. The court denied the motion in April 2021. On May 26, 2021, defendants moved the court to certify its order
denying the motion to dismiss for interlocutory appeal. Briefing on the motion was completed in June 2021, and that motion was denied on January 28, 2022. In May 2021, the parties each filed
respective initial discovery disclosures. On June 9, 2021, defendants filed their answer and affirmative defenses to the complaint and the parties engaged thereafter in discovery. On September 9,
2021, the U.S. government moved to intervene in the lawsuit and stay discovery until the parties entered into an amendment to their protective order that would prohibit the parties from requesting
discovery into certain matters, including communications with the U.S. government. The court ordered said amendment to the protective order on November 15, 2021 and discovery resumed. The
court further amended the protective order on October 17, 2022 and extended it until May 15, 2023. Following mediation, the parties reached a settlement of the lawsuit, under which defendants
agreed  to  pay  plaintiffs  $173  million.  On  May  26,  2023,  plaintiffs  filed  a  motion  for  preliminary  approval  of  the  settlement,  which  the  court  granted  on  June  9,  2023.  The  court  granted  final
settlement approval on September 7, 2023. The settlement was fully covered by insurance and has been paid in full.

Several shareholders have sent letters to the Exelon Board of Directors since 2020 demanding, among other things, that the Exelon Board of Directors investigate and address alleged breaches of
fiduciary duties and other alleged violations by Exelon and ComEd officers and directors related to the conduct described in the DPA. In the first quarter of 2021, the Exelon Board of Directors
appointed a Special Litigation Committee (SLC) consisting of disinterested and independent parties to investigate and address these shareholders' allegations and make recommendations to the
Exelon Board of Directors based on the outcome of the SLC's investigation. In July 2021, one of the demand letter shareholders filed a derivative action against current and former Exelon and
ComEd officers and directors, and against Exelon, as nominal defendant, asserting the same claims made in its demand letter. On October 12, 2021, the parties to the derivative action filed an
agreed motion to stay that litigation for 120 days in order to allow the SLC to continue its investigation, which the court granted. The stay has been extended several times. The parties participated
in a mediation in February 2023, but the matter did not resolve at that time. On April 26 and May 1, 2023, two additional demand letter shareholders each filed a separate derivative lawsuit against
current and former Exelon and ComEd officers and directors, and certain third parties, and against Exelon as nominal defendant, asserting claims similar to those made in their respective demand
letters. On May 25, 2023, certain demand letter shareholders (Settling Shareholders) filed a separate derivative lawsuit against current and former Exelon and ComEd officers and directors, and
against Exelon as nominal defendant, asserting claims similar to those made in their respective demand letters. The then pending derivative lawsuits were subsequently consolidated. On May 26,
2023, prior to lawsuit consolidation, the SLC filed a Notice of Determination and Intent to Seek Court Approval of Settlement (Notice of Determination). The Notice of Determination stated that,
through mediation efforts, a settlement of the derivative claims had been approved by the SLC, the Independent Review Committee of the Board (which had been formed in the third quarter of
2022, to ensure the Board’s consideration of any SLC recommendations would be independent and objective),

256

Note 18 — Commitments and Contingencies

the Board, and the Settling Shareholders (the Settling Parties). The Notice of Determination further specified the process by which the Settling Parties would seek court approval of the proposed
settlement and resolution and dismissal of all derivative claims and lawsuits, including any lawsuits or actions brought by demand letter shareholders who are not participating in the proposed
settlement. In furtherance of the proposed settlement, on June 16, 2023, the SLC filed a motion for preliminary approval of the settlement, attaching the Stipulation and Agreement of Settlement
(Stipulation), which contains the terms of the proposed settlement. The proposed settlement terms include but are not limited to: a payment of $40 million to Exelon by Exelon’s insurers of which
$10 million constitutes the attorneys’ fee award to be paid to the Settling Shareholders’ counsel; various compliance and disclosure-related reforms; and certain changes in Board and Committee
composition.  On  June  13,  2023,  the  non-settling  derivative  shareholders  filed  a  motion  asking  the  court  to  set  a  status  conference  to  discuss  lifting  the  discovery  stay.  On  June  29,  2023,  an
additional shareholder filed a separate derivative lawsuit against current and former Exelon and ComEd officers and directors, and against Exelon as nominal defendant, asserting claims similar to
those made in its demand letter. That lawsuit has been consolidated into the other pending derivative lawsuits. On June 30, 2023, the non-settling shareholders’ motion for status and the SLC’s
motion for preliminary approval was heard by the court, during which the court set a briefing schedule on the appropriate standard for evaluating the settlement and the proper scope of requested
discovery.  Following  briefing  and  a  hearing,  the  court  allowed  the  non-settling  shareholders  to  seek  certain,  limited  discovery,  which  the  SLC,  Independent  Review  Committee,  and  Exelon
responded  to  on  October  5,  2023.  On  October  11,  2023,  an  additional  non-settling  shareholder  filed  a  separate  derivative  lawsuit  against  current  and  former  Exelon  and  ComEd  officers  and
directors, and against Exelon as a nominal defendant, asserting claims similar to those made in its demand letter. That lawsuit has been consolidated into the other pending derivative lawsuits.
The SLC filed its renewed motion for preliminary approval on October 26, 2023, with supporting submissions filed by the Independent Review Committee, Exelon, and the settling shareholders on
that same day. The non-settling plaintiffs filed a response to the renewed motion for preliminary approval and supporting submissions on November 29, 2023, and the SLC Independent Review
Committee, Exelon and the Settling Shareholders filed their respective reply briefs on December 21, 2023. On January 16, 2024, the non-settling plaintiffs sought leave of court to file a sur-reply,
which the court granted on January 18, 2024.

In August 2022, the ICC concluded its investigation initiated on August 12, 2021 into rate impacts of conduct admitted in the DPA, including the costs recovered from customers related to the DPA and
Exelon's funding of the fine paid by ComEd. On August 17, 2022, the ICC issued its final order accepting ComEd's voluntary customer refund offer of approximately $38 million (of which about $31 million is
ICC jurisdictional; the remaining balance is FERC jurisdictional) that resolves the question of whether customer funds were used for DPA related activities. The customer refund includes the cost of every
individual or entity that was either (i) identified in the DPA or (ii) identified by ComEd as an associate of the former Speaker of the Illinois House of Representatives in the ICC proceeding. The ICC’s DPA
investigation  is  now  closed.  The  ICC  jurisdictional  refund  was  made  to  customers  during  the April  2023  billing  cycle,  as  required  by  the  ICC.  The  FERC  jurisdictional  refund  was  included  in  ComEd's
transmission formula rate update proceeding, filed on May 12, 2023. The filed transmission rate, inclusive of the FERC jurisdictional DPA refund, will appear on ComEd retail customers' bills for the June
2023 through May 2024 monthly billing periods, in the line designated as "Transmission Services Charge." The customer refund will not be recovered in rates or charged to customers and ComEd will not
seek or accept reimbursement or indemnification from any source other than Exelon. An accrual for the amount of the customer refund has been recorded in Regulatory assets in Exelon’s and ComEd’s
Consolidated Balance Sheets as of December 31, 2023.

Savings Plan Claim (Exelon). On December 6, 2021, seven current and former employees filed a putative ERISA class action suit in U.S. District Court for the Northern District of Illinois against Exelon,
its Board of Directors, the former Board Investment Oversight Committee, the Corporate Investment Committee, individual defendants, and other unnamed fiduciaries of the Exelon Corporation Employee
Savings  Plan  (Plan).  The  complaint  alleges  that  the  defendants  violated  their  fiduciary  duties  under  the  Plan  by  including  certain  investment  options  that  allegedly  were  more  expensive  than  and
underperformed  similar  passively-managed  or  other  funds  available  in  the  marketplace  and  permitting  a  third-party  administrative  service  provider/recordkeeper  and  an  investment  adviser  to  charge
excessive fees for the services provided. The plaintiffs seek declaratory, equitable and monetary relief on behalf of the Plan and participants. On February 16, 2022, the court granted the parties' stipulated
dismissal of the individual named defendants without prejudice. The remaining defendants filed

257

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 18 — Commitments and Contingencies

a motion to dismiss the complaint on February 25, 2022. On March 4, 2022, the Chamber of Commerce filed a brief of amicus curiae in support of the defendants' motion to dismiss. On September 22,
2022, the court granted Exelon’s motion to dismiss without prejudice. The court granted plaintiffs leave until October 31, 2022 to file an amended complaint, which was later extended to November 30,
2022.  Plaintiffs  filed  their  amended  complaint  on  November  30,  2022.  Defendants  filed  their  motion  to  dismiss  the  amended  complaint  on  January  20,  2023.  On  September  29,  2023,  the  court  again
granted Exelon's motion to dismiss but granted plaintiffs leave until October 20, 2023 to file a second amended complaint. Plaintiffs did not file an amended complaint by the deadline. On October 25, 2023,
the parties filed a joint Stipulation of Dismissal, which provides that plaintiffs agreed that they will not initiate an appeal from the dismissal of this matter, and the parties agree that each side shall bear their
own  costs  and  attorneys’  fees.  Plaintiffs  also  acknowledge  in  the  Stipulation  that  defendants  have  neither  paid  nor  agreed  to  pay  or  provide  any  monetary  or  equitable  remedy  in  connection  with  the
dismissal of this action. On October 27, 2023, the court entered final judgment dismissing the matter with prejudice. No loss contingencies have been reflected in Exelon’s consolidated financial statements
with respect to this matter.

General (All Registrants). The Registrants are involved in various other litigation matters that are being defended and handled in the ordinary course of business. The Registrants are also from time to
time subject to audits and investigations by the FERC and other regulators. The assessment of whether a loss is probable or reasonably possible, and whether the loss or a range of loss is estimable, often
involves a series of complex judgments about future events. The Registrants maintain accruals for such losses that are probable of being incurred and subject to reasonable estimation. Management is
sometimes unable to estimate an amount or range of reasonably possible loss, particularly where (1) the damages sought are indeterminate, (2) the proceedings are in the early stages, or (3) the matters
involve novel or unsettled legal theories. In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss.

19. Shareholders' Equity (All Registrants)

Equity Securities Offering (Exelon)

On August 4, 2022, Exelon entered into an agreement with certain underwriters in connection with an underwritten public offering (the “Offering”) of 11.3 million shares (the “Shares”) of its Common stock,
no par value (“Common Stock”). The Shares were sold to the underwriters at a price per share of $43.32. Exelon also granted the underwriters an option to purchase an additional 1.695 million shares of
Common stock also at the price per share of $43.32. On August 5, 2022, the underwriters exercised the option in full. The net proceeds from the Offering and the exercise of the underwriters’ option were
$563 million before expenses paid by Exelon. Exelon used the proceeds, together with available cash balances, to repay $575 million in borrowings under a $1.15 billion term loan credit facility. See Note
16 — Debt and Credit Agreements for additional information on Exelon’s term loan.

At-the-Market Program (Exelon)

On August 4, 2022, Exelon executed an equity distribution agreement (“Equity Distribution Agreement”), with certain sales agents and forward sellers and certain forward purchasers, establishing an ATM
equity distribution program under which it may offer and sell shares of its Common stock, having an aggregate gross sales price of up to $1.0 billion. Exelon has no obligation to offer or sell any shares of
Common stock under the Equity Distribution Agreement and may, at any time, suspend or terminate offers and sales under the Equity Distribution Agreement. In November and December 2023, Exelon
issued approximately 3.6 million shares of Common stock at an average gross price of $39.58 per share. The net proceeds from these issuances were $140 million, which were used for general corporate
purposes. As of December 31, 2023, $858 million of Common stock remained available for sale pursuant to the ATM program.

20. Stock-Based Compensation Plans (All Registrants)

Stock-Based Compensation Plans

Exelon  grants  stock-based  awards  through  its  LTIP,  which  primarily  includes  performance  share  awards,  restricted  stock  units,  and  stock  options. At  December  31,  2023,  there  were  approximately  33
million shares authorized for issuance under the LTIP. For the years ended December 31, 2023, 2022, and 2021, exercised and distributed stock-based awards were primarily issued from authorized but
unissued Common stock shares.

Separation-related Adjustments. In connection with the separation, Exelon and Constellation entered into an Employee Matters Agreement, effective February 1, 2022. Under the terms of the Employee
Matters Agreement, and pursuant to the terms of the LTIP, the Compensation Committee of the Board of Exelon approved an

259

Table of Contents

(Dollars in millions, except per share data unless otherwise noted)

Note 20 — Stock-Based Compensation Plans

adjustment  to  outstanding  awards  granted  under  the  LTIP  in  order  to  preserve  the  intrinsic  aggregate  value  of  such  awards  before  the  separation.  The  separation-related  adjustments  did  not  have  a
material  impact  on  either  compensation  expense  or  the  potentially  dilutive  securities  to  be  considered  in  the  calculation  of  diluted  earnings  per  share  of  Common  stock.  Former  Exelon  employees
transferred to Constellation as a result of the separation surrendered their outstanding unvested Exelon awards effective February 1, 2022.

The Registrants grant cash awards. The following table does not include expense related to these plans as they are not considered stock-based compensation plans under the applicable authoritative
guidance.

The  following  table  presents  the  stock-based  compensation  expense  included  in  Exelon's  Consolidated  Statements  of  Operations  and  Comprehensive  Income.  The  Utility  Registrants'  stock-based

Exelon receives a tax deduction based on the intrinsic value of the award on the exercise date for stock options and the distribution date for performance share awards and restricted stock units. For each
award,  throughout  the  requisite  service  period,  Exelon  recognizes  the  tax  benefit  related  to  compensation  costs.  The  following  table  presents  information  regarding  Exelon’s  realized  tax  benefit  when
distributed:

Performance share awards are granted under the LTIP. The performance share awards are settled 50% in common stock and 50% in cash at the end of the three-year performance period, except for
awards that are settled 100% in cash if certain ownership requirements are satisfied.

The common stock portion of the performance share awards is considered an equity award and is valued based on Exelon's stock price on the grant date. The cash portion of the performance share
awards is considered a liability award which is remeasured each reporting period based on Exelon’s current stock price. As the value of the common stock and cash portions of the awards are based on
Exelon’s stock price during the performance period, coupled with changes in the total shareholder return modifier and expected payout of the award, the compensation costs are subject to volatility until
payout is established.

For  nonretirement-eligible  employees,  stock-based  compensation  costs  are  recognized  over  the  vesting  period  of  three  years  using  the  straight-line  method.  For  performance  share  awards  granted  to
retirement-eligible employees, the value of the performance shares is recognized ratably over the vesting period, which is the year of grant. Exelon processes forfeitures as they occur for employees who
do not complete the requisite service period.

The following table summarizes Exelon’s nonvested performance share awards activity:

(a) As of December 31, 2023, $11 million of total unrecognized compensation costs related to nonvested performance shares are expected to be recognized over the remaining weighted-average period of 1.8 years.

Restricted Stock Units

Restricted  stock  units  are  granted  under  the  LTIP  with  the  majority  being  settled  in  a  specific  number  of  shares  of  common  stock  after  the  service  condition  has  been  met.  The  corresponding  cost  of
services is measured based on the grant date fair value of the restricted stock unit issued.

The  value  of  the  restricted  stock  units  is  expensed  over  the  requisite  service  period  using  the  straight-line  method.  The  requisite  service  period  for  restricted  stock  units  is  generally three  to  five  years.
However, certain restricted stock unit awards become fully vested upon the employee reaching retirement-eligibility. The value of the restricted stock units granted to retirement-eligible employees is either
recognized ratably over the first six months in the year of grant if the employee reaches retirement eligibility prior to July 1st of the grant year or through the date of which the employee reaches retirement
eligibility. Exelon processes forfeitures as they occur for employees who do not complete the requisite service period.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

All Registrants

None.

ITEM 9A.

CONTROLS AND PROCEDURES

All Registrants—Disclosure Controls and Procedures

During the fourth quarter of 2023, each of the Registrant's management, including its principal executive officer and principal financial officer, evaluated disclosure controls and procedures related to the
recording,  processing,  summarizing,  and  reporting  of  information  in  that  Registrant’s  periodic  reports  that  it  files  with  the  SEC.  These  disclosure  controls  and  procedures  have  been  designed  by  the
Registrants to ensure that (a) material information relating to that Registrant, including its consolidated subsidiaries, is accumulated and made known to that Registrant’s management, including its principal
executive officer and principal financial officer, by other employees of that Registrant and its subsidiaries as appropriate to allow timely decisions regarding required disclosure, and (b) this information is
recorded,  processed,  summarized,  evaluated,  and  reported,  as  applicable,  within  the  time  periods  specified  in  the  SEC’s  rules  and  forms.  Due  to  the  inherent  limitations  of  control  systems,  not  all
misstatements  may  be  detected.  These  inherent  limitations  include  the  realities  that  judgments  in  decision-making  can  be  faulty  and  that  breakdowns  can  occur  because  of  simple  error  or  mistake.
Additionally, controls could be circumvented by the individual acts of some persons or by collusion of two or more people.

Accordingly, as of December 31, 2023, the principal executive officer and principal financial officer of each of the Registrants concluded that such Registrant’s disclosure controls and procedures were
effective to accomplish its objectives.

All Registrants—Changes in Internal Control Over Financial Reporting

Each Registrant continually strives to improve its disclosure controls and procedures to enhance the quality of its financial reporting and to maintain dynamic systems that change as conditions warrant.
However, there have been no changes in internal control over financial reporting that occurred during the fourth quarter of 2023 that have materially affected, or are reasonably likely to materially affect,
any of the Registrant's internal control over financial reporting.

All Registrants—Internal Control Over Financial Reporting

Management is required to assess and report on the effectiveness of its internal control over financial reporting as of December 31, 2023. As a result of that assessment, management determined that
there  were  no  material  weaknesses  as  of  December  31,  2023  and,  therefore,  concluded  that  each  Registrant’s  internal  control  over  financial  reporting  was  effective.  Management’s  Report  on  Internal
Control Over Financial Reporting is included in ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

(1) Balance includes unvested performance shares, and unvested restricted stock units that were granted under the Exelon LTIP or predecessor company plans (including shares awarded under those plans and deferred
into the stock deferral plan) and deferred stock units granted to directors as part of their compensation. Unvested performance shares are subject to performance metrics and to a total shareholder return modifier.
Additionally, pursuant to the terms of the Exelon LTIP plan, 50% of final payouts are made in the form of shares of common stock and 50% is made in form of in cash, or if the participant has exceeded 200% of their
stock ownership requirement, 100% of the final payout is made in cash. For performance shares granted in 2021, 2022, and 2023, the total includes the maximum number of shares that could be issued assuming all
participants receive 50% of payouts in shares and assuming the performance and total shareholder return modifier metrics were both at maximum, representing best case performance, for a total of 2,401,852 shares. If
the performance and total shareholder return modifier metrics were at "target", the number of securities to be issued for such awards would be 1,200,926. The balance also includes 410,234 shares to be issued upon the
conversion of deferred stock units awarded to members of the Exelon board of directors. Conversion of the deferred stock units to shares of common stock occurs after a director terminates service to the Exelon board
or the board of any of its subsidiary companies. See Note 20 — Stock-Based Compensation Plans of the Combined Notes to Consolidated Financial Statements for additional information about the material features of
the plans.

1. Basis of Presentation

 Exelon Corporation and Subsidiary Companies 
Schedule I – Condensed Financial Information of Parent (Exelon Corporate)
 Notes to Financial Statements

Exelon Corporate is a holding company that conducts substantially all of its business operations through its subsidiaries. These condensed financial statements and related footnotes have been prepared in
accordance with Rule 12-04, Schedule I of Regulation S-X. These statements should be read in conjunction with the consolidated financial statements, and notes thereto, of Exelon Corporation.

As of December 31, 2023 and 2022, Exelon Corporate owned 100% of all of its significant subsidiaries, either directly or indirectly, except for Commonwealth Edison Company (ComEd), of which Exelon
Corporate owns more than 99%. As of February 1, 2022, as a result of the completion of the separation, Exelon Corporate no longer retains any equity ownership interest in Generation or Constellation.
The separation of Constellation, including Generation and its subsidiaries, met the criteria for discontinued operations and as such, results of operations are presented as discontinued operations and have
been excluded from continuing operations for all periods presented. Accounting rules require certain BSC costs previously allocated to Generation to be presented as part of Exelon’s continuing operations
as these costs do not qualify as expenses of the discontinued operations. Comprehensive income and cash flows related to Generation have not been segregated and are included in the Condensed
Statements of Operations and Comprehensive Income and Condensed Statements of Cash Flows, respectively, for all periods presented. See Note 2 — Discontinued Operations of the Combined Notes to
Consolidated Financial Statements for additional information.

See Note 15—Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for Exelon Corporate’s derivatives.

4. Debt and Credit Agreements

Short-Term Borrowings

Exelon Corporate meets its short-term liquidity requirements primarily through the issuance of commercial paper. Exelon Corporate had $527 million in outstanding commercial paper borrowings as of
December 31, 2023 and $449 million outstanding commercial paper as of December 31, 2022.

Revolving Credit Agreements

As  of  December  31,  2023,  Exelon  Corporation  had  a  $900  million  aggregate  bank  commitment  under  its  existing  syndicated  revolving  facility  in  which  $370  million  was  available  to  support  additional
commercial  paper  as  of  December  31,  2023.  See  Note  16  —  Debt  and  Credit Agreements  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  regarding  Exelon
Corporate’s credit agreement.

On  February  1,  2022,  Exelon  Corporate  entered  into  a  new  5-year  revolving  credit  facility  with  an  aggregate  bank  commitment  of  $900  million  at  a  variable  interest  rate  of  SOFR  plus  1.275%  which
replaced its existing $600 million syndicated revolving credit facility.

EXELON CORPORATION  SENIOR MANAGEMENT SEVERANCE PLAN (As Amended and Restated)

EXELON CORPORATION  SENIOR MANAGEMENT SEVERANCE PLAN (As Amended and Restated) 1. PURPOSE OF THE PLAN The Exelon Corporation Senior Management Severance Plan, as amended and restated  herein (the “Plan”), is effective as of February 1, 2024 (the “Effective Date”) except as otherwise  specifically provided herein, and supersedes in its entirety all prior versions of the Plan with  respect to any Termination of Employment occurring on or after the Effective Date. The Plan is  intended to encourage the attraction and retention of executives of Exelon Corporation  (“Exelon”) and its participating subsidiaries.  2. ELIGIBILITY Each employee of the Company selected by the Plan Administrator whose position is in Salary Band E09 or above (an “Executive”) shall be eligible to participate in the Plan in the event of his or her Termination of Employment, other than an Executive whose Termination of  Employment is governed by the terms and conditions of another separation or change in control plan or agreement between such Executive and the Company or an affiliate thereof. 3. PARTICIPATION  Each eligible Executive shall become a participant in the Plan (a “Participant”) as of his or her Termination Date, subject to his or her timely execution of, and compliance with the terms and conditions of (a) a separation agreement with the Company (“Separation Agreement”),  (b) a waiver and release of claims which has become irrevocable (“Waiver and Release”) and (c)  non-solicitation, confidential information, and intellectual property covenants and, in the discretion of the Plan Administrator, non-competition covenants (collectively, “Restrictive Covenants”), each of the foregoing documents in such form as the Plan Administrator, in its sole discretion, may require.  4. BENEFITS  In addition to payment of all Accrued Obligations, a Participant shall be entitled to the following benefits upon his or her Termination of Employment:  4.1. Severance Pay. Continued payment of (a) his or her Base Salary, and (b) if the Participant is a participant in the Annual Incentive Award Plan for the year in which the Termination Date occurs, his or her Target Incentive, each payable during the Severance Period in substantially equal regular payroll installments commencing within 45 days after his or her Termination Date.  4.2. Annual Incentive Awards. Each Participant who is a participant in the Annual Incentive Award Plan for the year in which the Termination Date occurs shall remain eligible to receive a pro-rated Annual Incentive based on the number of days elapsed during such year as of the Termination Date, payable at the time such awards are paid to active  employees for such

year (but not later than March 15 of the year following the

 
2  Termination Date).  A Participant who is not a participant in the Annual Incentive  Award Plan for the year in which the Termination Date occurs shall not be entitled to an Annual Incentive for such year, and the amount (if any) payable under any other annual incentive plan in which the Participate participates for such year shall be determined by  the Plan Administrator in its sole discretion.  4.3. Long-Term Incentive Awards. Each of the Participant’s outstanding awards (if any) under the LTIP, including stock options, restricted stock, restricted stock units, restricted cash, performance shares, performance units and similar stock or cash incentive awards, shall become vested and payable to a Participant solely to the extent (and at the time)  provided under the terms of the LTIP, applicable program and/or award agreement under  which such awards are granted.  4.4. Health Care Coverage. (a) COBRA Coverage. During the Severance Period, a Participant (and his or  her eligible dependents) who so elects shall be eligible to participate in the  health care plans under which he or she was covered immediately prior to the Termination Date, in accordance with and subject to the terms and conditions of such plans as in effect from time to time.  The Participant’s out of pocket costs (including premiums, deductibles and co-payments) for  such coverage shall be the same as those in effect from time to time for active peer employees during such period. Such coverage shall be provided during the Severance Period in satisfaction of continuation coverage under Section 4980B of the Code and Section 601 to 609 of  ERISA (“COBRA”) for such period.  At the end of the Severance Period, COBRA continuation coverage at the Participant’s expense may be  continued for any remaining balance of the statutory COBRA coverage period. (b) Retiree Coverage.  A Participant who is in a classification and position  eligible for retiree coverage as of his or her Termination Date and who, as  of the last day of the Severance Period, has attained at least age 50 and completed at least 10 years of service (or who has completed such other  age and service requirement then in effect under the Exelon Corporation  Severance Benefit Plan or any successor plan as of the relevant time set  forth in such plan) shall be entitled to elect to participate in such Company  group health care programs that are then available to similarly situated retirees of his or her legacy Company who terminate employment as of the  Termination Date. The eligibility for coverage and availability of  programs or plans, the amounts charged for coverage, and the other terms,  conditions and limitations under the Company’s group health care programs or plans shall remain

subject to the Company’s right to amend,  change or terminate such programs or plans at any time. 4.5. SERP / Other Deferred Compensation. With respect to a Participant who has a vested benefit and actively participates in a defined benefit pension plan as of his or her Termination Date, the Severance Period (but not to exceed 24 months) shall be taken into

 
3  account as service solely for purposes of determining, to the extent relevant under the qualified defined benefit pension plan then covering the Participant, the amount of the Participant’s regular accrued SERP benefit, but not for purposes of determining eligibility  for early retirement benefits (including any social security supplement) or any other purpose.  In determining the amount of the Participant’s benefit, if any, the severance payments made under Section 4.1 shall be considered as if such payments were normal  base salary and incentive payments. All amounts previously deferred by, or accrued to the benefit of, such Participant under a non-qualified deferred compensation plan of the  Company shall, to the extent vested, be paid in accordance with the Participant’s distribution election in effect thereunder as of the Termination Date (or, if no affirmative election is in effect as of such date, the default election applicable to the Participant).  4.6. Life Insurance and Disability Coverage.  A Participant shall be eligible for continued  coverage under the applicable life insurance and executive-only long term disability plans  sponsored by the Company (or other equivalent coverage or benefits) through the last day  of the Severance Period applicable to such Participant on the same terms and subject to  the same terms and conditions as are applicable to active peer employees (including,  without limitation, submission of proof by an Executive who seeks long term disability  benefits that such Executive would have satisfied the conditions for such benefits had the Executive been an employee during the Severance Period and terminated employment on  or before the last day of such period). 4.7. Outplacement and Financial Counseling Services.  During the twelve-month period following the Termination Date, the Company shall reimburse the Participant for reasonable fees as incurred for services rendered by a professional outplacement organization approved by the Plan Administrator to provide individual outplacement  services, and the Participant shall be eligible to receive financial counseling services  consistent with the terms and conditions applicable to active peer executives under  Exelon’s executive perquisite policy.  5. CHANGE IN CONTROL BENEFITS  A Participant, whose Termination Date occurs during the period commencing ninety (90)  days before a Change Date and ending on the second anniversary of such Change Date, shall be entitled to the payment of all Accrued Obligations and the following benefits in lieu of the benefits described in Section 4 hereof: 5.1. Severance Pay. Continued payment of (a) his or her Base Salary, and (b) if the Participant  is a participant in the Annual

Incentive Award Plan for the year in which the Termination Date occurs, his or her Target Incentive, each payable during the Severance Period in substantially equal regular payroll installments commencing within 45 days after his or  her Termination Date. 5.2. Annual Incentive for Year of Termination.  A pro-rated Annual Incentive under the annual incentive plan applicable to such Participant for the year in which the Termination  Date occurs, based on the number of days elapsed during such year as of the Termination  Date, payable at the time such awards are paid to active employees for such year (but not later than March 15 of the year following the Termination Date).

 
4  5.3. Long-Term Incentive Awards. (a) Stock Options. Each outstanding stock option granted to the Participant under the LTIP shall (i) become fully vested as of the Termination Date,  and (ii) thereafter remain exercisable until the fifth anniversary of the  Termination Date or, if earlier, the expiration date of any such stock option, provided that this provision shall not limit the right of the Company to cancel  such stock options in connection with a Change in Control in accordance with the terms and conditions of the LTIP. (b) Restricted Stock, Stock Unit and Cash Awards. All forfeiture conditions  that are applicable as of the Termination Date to any outstanding shares of  restricted stock, restricted stock units or restricted cash awarded to the  Participant under the LTIP shall (except as expressly provided to the contrary in such awards) lapse and such awards shall become fully vested as of the Termination Date. (c) Other LTIP Awards.  To the extent the performance period applicable to any outstanding performance shares, performance units or similar stock or  cash incentive awards granted to the Executive under the LTIP has ended as of the  Termination Date (or, if later, the Change Date), including performance periods that are terminated early in connection with the Change in Control, such awards shall become fully vested and payable (to  the extent not already paid), based on the performance level attained (or  deemed to have been attained in connection with the Change in Control). To the extent the performance period applicable to any such award has not  ended as of the Termination Date (or, if later, the Change Date), such  award shall become fully vested and payable based on the extent to which  the performance goals established under the LTIP for such performance  period are attained as of the last day of the performance period. 5.4. Make-Whole if Termination Date Precedes Change Date.  Notwithstanding the foregoing provisions of this Section 5, in the event the Participant’s Termination Date occurs during  the 90-day period preceding the Change Date, then (i) any payments that would have been to the Participant earlier under Sections 5.1 or 5.2, had the Change Date preceded  his or her Termination Date, will be paid in a lump sum within 45 days after the Change Date, (ii) none of the Participant’s LTIP awards described in Section 5.3 shall expire or  be forfeited during the 90-day period preceding the Change Date, except to the extent they would have expired or been forfeited had the Participant remained employed until  the Change Date, and (iii) any lapse of restrictions and vesting of such LTIP awards that would have occurred as of the Termination Date, had it been preceded by the Change

Date, shall occur as of the Change Date. 5.5. Continuation of Welfare Benefits. (a) COBRA Coverage. During the Severance Period, a Participant (and his or  her dependents) who so elects shall be eligible to participate in the health care plans under which he or she was covered immediately prior to the Termination Date, in accordance with and subject to the terms and

 
5  conditions of such plans as in effect from time to time.  The Participant’s out of pocket costs (including premiums, deductibles and co-payments) for  such coverage shall be the same as those in effect from time to time for active peer employees during such period. Such coverage shall be provided during the Severance Period in satisfaction of continuation coverage under COBRA for such period.  At the end of the Severance Period, COBRA continuation coverage at the Participant’s expense may  be continued for the remaining balance of the statutory COBRA coverage period, if any.  (b) Retiree Coverage.  A Participant who is in a classification and position  eligible for retiree coverage as of his or her Termination Date and who, as  of the last day of the Severance Period, has attained at least age 50 and completed at least 10 years of service (or who has completed such other  age and service requirement then in effect under the Exelon Corporation  Severance Benefit Plan or any successor plan as of the relevant time set  forth in such plan) shall be entitled to elect to participate in such Company  group health care programs that are then available to similarly situated retirees of his or her legacy Company who terminate employment as of the  Termination Date. The eligibility for coverage and availability of  programs or plans, the amounts charged for coverage, and the other terms,  conditions and limitations under the Company’s group health care programs or plans shall remain subject to the Company’s right to amend, change or terminate such programs or plans at any time. 5.6. SERP/ Other Deferred Compensation. For purposes of the Participant’s SERP benefit (if  the Participant then actively participates in a defined benefit pension plan), the Severance  Period (but not to exceed 24 months) shall be taken into account as service solely for  purposes of determining whether the Participant is vested and, to the extent relevant under the qualified defined benefit pension plan then covering the Participant, the amount  of the Participant’s regular accrued SERP benefit, but not for purposes of determining eligibility for early retirement benefits (including any social security supplement) or any other purpose. In determining the amount of the Participant’s vested benefit, if any, the  severance payments made under Section 5.1 shall be considered as if such payments were  normal base salary and incentive payments. All amounts previously deferred by, or  accrued to the benefit of, such Participant under a non-qualified deferred compensation  plan of the Company shall, to the extent vested, be paid in accordance with the Participant’s distribution election in effect thereunder as of the Termination Date (or, if 

affirmative election is in effect as of such date, the default election applicable to the Participant)  5.7. Life Insurance and Disability Coverage.  A Participant shall be eligible for continued  coverage under the applicable life insurance and executive-only long term disability plans  or programs sponsored by the Company (or other equivalent coverage or benefits)  through the last day of the Severance Period applicable to such Participant on the same  terms and subject to the same terms and conditions as are applicable to active peer  employees (including, without limitation, submission of proof by an Executive who seeks  long term disability benefits that such Executive would have satisfied the conditions for

 
6  such benefits had the Executive been an employee during the Severance Period and terminated employment on or before the last day of such period). 5.8. Outplacement and Financial Counseling Services.  During the 12-month period following  the Termination Date, the Company shall pay or cause to be paid on behalf of such Participant, as incurred, all reasonable fees and costs charged by a nationally recognized outplacement firm selected by such Participant for outplacement services. During such period, the Participant also shall be eligible to receive financial counseling services consistent with the terms and conditions applicable to active peer executives under  Exelon’s executive perquisite policy as of the Termination Date.  5.9. Procedural Requirements. The Company shall strictly observe or cause to be strictly observed each of the following procedures in connection with any termination for Cause during the period commencing on a Change Date and ending on the second anniversary of such Change Date:  an eligible Executive’s termination of employment shall not be deemed to be for Cause unless and until there shall have been delivered to such Executive  a written notice of the determination of the Chief Executive Officer of the Company  which is the Executive’s employer (“CEO”) (after reasonable written notice of such consideration by the CEO of acts or omissions alleged to constitute Cause is provided to such Executive and such Executive is given an opportunity to present a written response to the CEO regarding such allegations), finding that, in his or her good faith opinion, such  Executive’s acts, or failure to act, constitutes Cause and specifying the particulars thereof  in detail.  5.10. Sole and Exclusive Obligations. The obligations of the Company under this Plan with respect to any Termination of Employment under this Section 5 shall supersede and not  duplicate any severance obligations of the Company in any other plan of the Company or  prior agreement between such Participant and the Company or its predecessor in interest. 5.11. Payment Capped. If the Plan Administrator determines that any benefits paid or payable  under this Plan to a Participant would give rise to liability of the Participant for the excise  tax imposed by Section 4999 of the Code or any successor provision, then the amount payable to the Participant hereunder shall be reduced by the Company to the extent necessary so that no portion is subject to such excise tax; provided, however, such  reduction shall be made only if it results in the Participant retaining a greater amount of  benefits on an after-tax basis (taking into account the excise tax and applicable federal,  state, and local income

and payroll taxes) than the amount of benefits on an after-tax basis (taking into account the excise tax and applicable federal, state, and local income and payroll taxes) the Participant would have retained absent such reduction.  In the event benefits are required to be reduced pursuant to this Section 5.11, then they shall be reduced in the following order of priority in a manner consistent with Section 409A of the Code: (i) first from cash benefits (ii) next from performance-vested equity benefits,  with benefits having later payments dates being reduced first;  (iii) next from time-vested  equity benefits, with benefits having later payment dates being reduced first; and (iv) in  the case of equity benefits having the same payments dates, pro-rata amongst all such benefits. The Plan Administrator shall, in its sole discretion, choose an independent public accounting firm or professional consulting services provider of national reputation  and experience to make in writing in good faith all calculations and determinations under

 
7  this Section 5.11 including the assumptions to be used in arriving at any calculations.  For  purposes of making the calculations and determinations under this Section 5.11, the accountants may make reasonable assumptions and approximations concerning the application of Sections 280G and 4999 of the Code.  The Plan Administrator shall furnish  to the accountants information and documents as the Accountants may reasonably request  to make the calculations and determinations under this Section 5.11 and shall bear all costs the accountants incur in connection with any calculations contemplated hereby.  6. TERMINATION OF PARTICIPATION; CESSATION OF BENEFITS; RECOUPMENT A Participant’s benefits under the Plan shall terminate on the last day of the Participant’s Severance Period; provided that a Participant’s right to benefits shall terminate immediately on  the date that the Participant breaches any of the terms of his or her Separation Agreement,  Restrictive Covenants or Waiver and Release, or if at any time the Company determines (in accordance with Section 5.9 with respect to a Participant receiving benefits under Section 5) that in the course of his or her employment the Executive engaged in conduct described in Section 7.5(b), (c), (d) or (e), in which case the Company may require the repayment of amounts paid pursuant to Section 4 or Section 5 (other than any Accrued Obligations) prior to such breach or other conduct, and shall discontinue the payment of any additional amounts under the Plan. To the extent that the Company makes payments and provides benefits to an Executive  and the Executive either does not timely execute and deliver the Waiver and Release to the Company or revokes the Waiver and Release in accordance with its terms, Executive shall pay to  the Company within 10 days following the expiration of the consideration period of the Waiver and Release or the date such Waiver and Release was revoked, a lump sum payment of all payments and the value of all benefits (other than Accrued Obligations) received by Executive to  date hereunder. Notwithstanding any provision of the Plan or any Separation Agreement to the contrary, benefits paid or payable to a Participant under the Plan shall be subject to any executive or officer recoupment or claw back policy of the Board of Directors (including but not limited to Exelon’s Financial Restatement Compensation Recoupment Policy), as in effect from time to time. Any termination and/or recoupment of benefits under the Plan shall be in addition and without prejudice to any other remedies that the Company may elect to assert. 7.

13 9. ADMINISTRATION OF THE PLAN The Plan shall be administered on a day-to-day basis by the Plan Administrator.  The  Plan Administrator has the sole and absolute power and authority to interpret and apply the provisions of this Plan to a particular circumstance, make all factual and legal determinations, construe uncertain or disputed terms and make eligibility and benefit determinations in such  manner and to such extent as the Plan Administrator, in his or her sole discretion may determine.  Benefits under the Plan will be paid only if the Plan Administrator, in his or her discretion, determines that an individual is entitled to them; provided, however, that any dispute after the claims procedure under Section 10 has been exhausted regarding whether an Executive’s termination of employment for purposes of Section 5 is based on either Good Reason or Cause  may, at the election of the Executive, be submitted to binding arbitration pursuant to Section 11. The Plan Administrator may promulgate any rules and regulations it deems necessary to carry out the purposes of the Plan or to interpret the terms and conditions of the Plan; provided, however, that no rule, regulation or interpretation shall be contrary to the provisions of the Plan. The rules, regulations and interpretations made by the Plan Administrator shall, where appropriate, be applied on a consistent basis with respect to similarly situated Executives, and shall be final and binding on any Executive or former Executive and any successor in interest. The Plan Administrator may delegate any administrative duties, including, without limitation, duties with respect to the processing, review, investigation, approval and payment of severance pay and provision of severance benefits, to designated individuals or committees.  The  Plan Administrator may amend any Participant’s Separation Agreement to the extent the Plan Administrator determines it is reasonably necessary or appropriate to do so to comply with section 409A of the Code.  10. CLAIMS PROCEDURE  The Plan Administrator shall determine the status of an individual as an Executive and the eligibility and rights of any Executive or former Executive as a Participant to any severance pay or benefits hereunder.  Any Executive or former Executive who believes that he or she is entitled to receive severance pay or benefits under the Plan, including severance pay or benefits other than those initially determined by the Plan Administrator, may file a claim in writing with the Plan Administrator. Within 90 days after the receipt of the claim the Plan Administrator  shall either allow or deny the claim in writing, unless special circumstances require an extension of

time for processing, in which case a decision shall be rendered as soon as practicable, but not later than 180 days after receipt of a request for review. A claimant whose claim is denied (or his or her duly authorized representative) may,  within 60 days after receipt of the denial of his or her claim, request a review upon written application to Exelon’s Chief Human Resources Officer or other officer designated by Exelon and specified in the claim denial; review (without charge) relevant documents; and submit  written comments, documents, records and other information relating to the claim.  The Chief Human Resources Officer or other designated officer shall notify the claimant of his or her decision on review within 60 days after receipt of a request for review unless special  circumstances require an extension of time for processing, in which case a decision shall be rendered as soon as possible, but not later than 120 days after receipt of a request for review.

 
14 Notice of the decision on review shall be in writing.  The officer’s decision on review shall be final and binding on any claimant or any successor in interest.  In reviewing a claim or an appeal of a claim denial, the Plan Administrator and the Chief Human Resources Officer or other officer designated by Exelon shall have all of the powers and authority granted to the Plan Administrator pursuant to Section 9. 11. STATUTE OF LIMITATIONS; ARBITRATION  No Executive (or representative thereof) may bring any legal or equitable action to recover benefits under the Plan until he or she has exhausted the internal claims and appeals  process described above. Any such action must be commenced no later than the first anniversary of a final decision on a claim for benefits (or such earlier date provided in any applicable statute of limitations). Any such action shall be brought exclusively in the federal courts in the  Northern District of Illinois, provided that any dispute, controversy or claim between the parties hereto concerning whether an Executive’s termination of employment for purposes of Section 5 is based on either Good Reason or Cause may, at the election of the Executive, be settled by  binding arbitration in Chicago, Illinois, before an impartial arbitrator pursuant to the rules and regulations of the American Arbitration Association (“AAA”) pertaining to the arbitration of  commercial disputes.  The costs and fees of the arbitrator shall be borne equally by the parties,  regardless of the result of the arbitration. Notwithstanding anything to the contrary contained in  this Section or elsewhere in this Plan, any party may seek relief in the form of specific performance, injunctive or other equitable relief in order to enforce the decision of the arbitrator, and the Company may seek injunctive relief to enforce the above-referenced statutes of  limitations.  12. AMENDMENT OR TERMINATION OF PLAN The Talent Management and Compensation Committee of Exelon’s Board of Directors  (or its delegate) may amend, modify or terminate the Plan at any time, and Exelon’s Chief  Human Resources Officer may amend the Plan without action of such Committee with respect to  matters other than eligibility and severance levels of executive officers at any time; provided, however, that no amendment, modification or termination shall deprive any Participant of any payment or benefit that the Plan Administrator previously has determined is payable under the  Plan. Notwithstanding the foregoing, no amendment or termination that reduces the severance payments or materially adversely affects any Participant’s other benefits under Section 5 shall become effective as to such Participant during the

24-month period following a Change Date unless such Participant consents to such termination or amendment. Any purported Plan termination or amendment in violation of this Section 12 shall be void and of no effect.  13. MISCELLANEOUS 13.1. Limitation on Rights. Participation in the Plan is limited to the individuals described in  Sections 2 and 3, and the benefits under the Plan shall not be payable with respect to any voluntary or involuntary termination of employment that is not a Termination of Employment.  13.2. Offset; No Mitigation.

 
15 (a) To the extent permitted by Section 409A of the Code, the amount of a Participant’s payments under Section 4 of this Plan may be reduced to the extent necessary to defray amounts owed by the Participant due to unused  expense account balances, overpayment of salary, awards or bonuses,  advances or loans.  (b) A Participant shall not have any duty to mitigate the amounts payable by the Company under this Plan by seeking new employment following termination. Except as specifically otherwise provided in this Plan, all  amounts payable pursuant to this Plan shall be paid without reduction  regardless of any amounts of salary, compensation or other amounts which  may be paid or payable to the Executive as the result of the Executive’s  employment by another, unaffiliated employer. 13.3. Indemnification. Each Participant shall be indemnified and held harmless by the Company to the greatest extent permitted under applicable law and the Company’s by- laws (as in effect immediately preceding the Change Date with respect to a termination pursuant to Section 5) if such Participant was, is, or is threatened to be, made a party to  any pending, completed or threatened action, suit, arbitration, alternate dispute resolution  mechanism, investigation, administrative hearing or any other proceeding brought by a  third party whether civil, criminal, administrative or investigative, and whether formal or informal, by reason of the fact that such Participant is or was, or had agreed to become, a director, officer, employee, agent, or fiduciary of the Company or any other entity which such Participant is or was serving at the request of the Company (“Proceeding”), against all expenses (including all reasonable attorneys’ fees) and all claims, damages, liabilities and losses incurred or suffered by such Participant or to which such Participant may become subject for any reason; provided, that the Participant provides the Plan Administrator written notice of any such Proceeding promptly after receipt and such that the Company’s ability to defend shall not be prejudiced in any fashion and the Company shall have the right to direct the defense, approve any settlement and shall not be required  to indemnify the Participant in connection with any proceeding initiated by the Participant, including a counterclaim or crossclaim.  13.4. Severability.  If any one or more Sections, subsections or other portions of this Plan are declared by any court or governmental authority to be unlawful or invalid, such  unlawfulness or invalidity shall not serve to invalidate any Section, subsection or other  portion not so declared to be unlawful or invalid.  Any Section, subsection or other portion so declared to be

unlawful or invalid shall be construed so as to effectuate the terms of such Section, subsection or other portion to the fullest extent possible while  remaining lawful and valid. Notwithstanding the foregoing, in the event a determination is made that the Restrictive Covenants are invalid or unenforceable in whole or in part,  then the Separation Agreement with respect to the Participant subject to such  determination shall be void and the Company shall have no obligation to provide benefits  under this Plan to such Participant. 13.5. Governing Law. The Plan shall be construed and enforced in accordance with the  applicable provisions of ERISA and Section 409A of the Code.

 
16 13.6. No Right to Continued Employment. Nothing in this Plan shall guarantee the right of a  Participant to continue in employment, and the Company retains the right to terminate a Participant’s employment at any time for any reason or for no reason.  13.7. Successors and Assigns. This Plan shall be binding upon and inure to the benefit of Exelon and its successors and assigns and shall be binding upon and inure to the benefit of a Participant and his or her legal representatives, heirs and legatees. No rights, obligations or liabilities of a Participant hereunder shall be assignable without the Plan Administrator’s prior written consent. In the event of the death of a Participant prior to receipt of severance pay or benefits to which he or she is entitled hereunder (and, with respect to benefits under Section 4 or Section 5, after he or she has signed the Waiver and  Release), the severance pay described in Section 4.1 or 5.1, as applicable, shall be paid to  his or her estate, and the Participant’s dependents who are covered under any health care plans maintained by the Company shall be entitled to continued rights under Section 4.4 or Section 5.5, as applicable; provided that the estate or other successor of the Participant has not revoked such Waiver and Release. 13.8. Notices.  All notices and other communications under this Plan shall be in writing and  delivered by hand, by nationally recognized delivery service that promises overnight  delivery, or by first-class registered or certified mail, return receipt requested, postage prepaid, addressed as follows: (a) If to a Participant, to such Participant at his most recent home address on file with the Company; (b) If to the Company, to the Plan Administrator;  (c) or to such other address as either party shall have furnished to the other in  writing. Notice and communications shall be effective upon notice of delivery to the addressee. 13.9. Tax Withholding.  The Company may withhold from any amounts payable under this  Plan or otherwise payable to a Participant or beneficiary any federal, state, city and other taxes the Company determines to be appropriate under applicable law and may report all such amounts payable to such authority in accordance with any applicable law or regulation.  13.10. Section 409A and Changes to Law. (a) It is the intention of the Company that the provisions of this Plan comply with Section 409A of the Code, and all provisions of this Plan shall be construed and interpreted in a manner consistent with Section 409A of the  Code.  The Company shall administer and operate this Plan in compliance  with Section 409A of the Code and any rules, regulations or other guidance promulgated thereunder as in effect from time to time

and in the event that the Company determines that any provision of this Plan does not comply with Section 409A of the Code or any such rules, regulations or guidance and that as a result any Participant may become subject to a  tax under Section 409A of the Code, notwithstanding Section 12, the

 
17 Company shall have the discretion to amend or modify such provision to avoid the application of such tax, and in no event shall any Participant’s  consent be required for such amendment or modification.

(d) To the extent any amounts under this Plan are payable by reference to a Participant’s Termination of Employment, such term and similar terms shall be deemed to refer to such Participant’s “separation from service,”  within the meaning of Section 409A of the Code.  Notwithstanding any  other provision in this Plan, to the extent any payments hereunder constitute “nonqualified deferred compensation,” within the meaning of

Section 409A of the Code (a “Section 409A Payment”), and the  Participant is a specified employee, within the meaning of Treasury Regulation Section 1.409A 1(i), as determined by the Company in  accordance with any method permitted under Section 409A of the Code, as of the date of the Participant’s separation from service, each such Section 409A Payment that is payable upon such Participant’s separation

 
18 from service and would have been paid prior to the six-month anniversary  of such Participant’s separation from service, shall be delayed until the earlier to occur of (i) the six-month anniversary of Participant’s separation  from service and (ii) the date of Participant’s death.  Further, to the extent  that any amount is a Section 409A Payment and such payment is  conditioned upon Participant’s execution of a release and which is to be  paid or provided during a designated period that begins in one taxable year  and ends in a second taxable year, then such Section 409A Payment shall be paid or provided in the later of the two taxable years.

Any tax gross-up payment payable to a Participant, whether under this Plan or otherwise, shall be paid to the Participant or to the applicable taxing authorities on the Participant’s behalf as soon as practicable after the related taxes are due, but in any event not later than the last day of the calendar year  following the calendar year in which the related taxes are remitted to the  taxing authorities.

Powering a cleaner and brighter future  for our customers and communities. Our Purpose01 ©Exelon Corporation.  2024. All rights reserved. Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024

 
Our Values We are dedicated to safety We are committed to maintaining the highest  standards of safety and reliability for our people,  our customers and the communities in which we work. As a fundamental part of our culture and  operations, every member of the Exelon team is dedicated to putting safety first. We actively pursue excellence We are driven to excel. Recognizing the value  of constant improvement, we reach beyond compliance to advance our processes and  develop more efficient energy. In all we do,  we passionately exceed the standards of our industry – and those we set for ourselves – creating value for our  shareholders, customers and communities. We innovate to better  serve our customers We see challenge as an opportunity to exercise our ingenuity and our competitive spirit. We  encourage curiosity and exploration to develop  better ways of delivering clean energy.  We innovate with focus and intent, creating the solutions that matter most for our customers. We act with integrity and are accountable  to our communities and the environment We are committed to doing what’s right.  A deep connection to the communities we serve compels  us to take responsibility for our work, and we actively look for ways to engage and give back. We value the environment and work to reduce  our impact with future generations in mind. We succeed as an  inclusive and diverse team We foster an inclusive culture of trust, collaboration, and performance. We welcome and respect people with different perspectives,  backgrounds, and traits because we know that diverse teams drive powerful outcomes. Our Values ©Exelon Corporation.  2024. All rights reserved. 2 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024

 
To deliver on our vision to provide reliable, clean, and affordable energy, each of us – our system  engineers, customer support personnel, data  analysts, security staff, administrative personnel, and senior executives – must play a key role  in building a brighter, more sustainable future.  How we run our business is just as crucial as the results we achieve. Our shared values shape how we work with each other, our customers and our communities. They reflect what is truly important to us as an  organization. 02 Performance that Drives Progress They serve as the foundation of our culture and  the Exelon Code of Business Conduct (the Code), and help guide behavior and decision making across Exelon. Wherever we operate, each one of us represents Exelon. Each of us is the face of the company in our local communities. Living the values every  day and following the Code sets us apart from other companies and ensures performance that  drives progress. 3Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Because we actively pursue excellence, each of us must reach beyond compliance. Setting the bar high strengthens our reputation as an  industry leader and is the right way to conduct  our business. While the Code cannot describe all situations where questions of ethics may arise, it is a resource for making effective, ethical business  decisions. It enables us to identify situations that may raise ethical and legal issues. It also helps us  understand what Exelon expects of each of us. 03 Following the Code We are all accountable for following the Code. Specifically, the Code applies to: • Employees, officers, and directors of Exelon and its subsidiaries • Third party vendors and contractors must adhere to the Code’s principles described  in the Exelon Supplier Code of Conduct 4 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation.  2024.

Our Responsibilities04 ©Exelon Corporation. 2024. All rights reserved. Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024

 
We are all responsible for understanding and following the Code. In addition to its specific provisions, the Code requires that we: • Act with integrity • Have the courage to do the right thing • Foster a culture of safety and commitment  to high ethical standards through actions and words • Hold ourselves and others accountable • Are honest • Follow the law, regulatory requirements  and Exelon policies when conducting company business • Treat everyone with respect and decency  • Use common sense and good judgment • Promptly seek guidance when unsure about the right thing to do • Speak up when we see a problem ©Exelon Corporation.  2024. All rights reserved. 6 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024

 
Special Responsibilities  of Managers and Supervisors Managers and Supervisors must: • Demonstrate the highest ethical standards and quality in their work and hold others to the same standards • Treat others with respect, while ensuring  appropriate accountability  • Not bend the rules or pressure others to do so • Understand and communicate laws, regulations, policies, and procedures  affecting their areas of operation with support from the Legal Department,  Compliance & Ethics, and other company subject matter experts • Encourage team members to speak up  without fear of retaliation • Exercise meaningful oversight of employee actions implicating compliance  and ethics • Act to prevent problems before they happen, and intervene early as problems emerge • Report problems or possible violations to Compliance & Ethics, HR, or the Legal Department  • Promptly seek guidance when they are unsure about the right thing to do While we are all expected to do our part in understanding and following the Code, Exelon managers – from first-line supervisors to senior leaders – have an additional responsibility to lead by example and uphold our values. Oversight of External Business Partners Employees who engage or are responsible for overseeing external business partners must: • Provide effective oversight of vendors and contractor personnel to ensure third parties adhere to applicable contract terms, provisions of the Exelon Supplier Code  of Conduct, and company policies and  procedures  • Take action – up to and including terminating a contract – if a vendor fails to honor its contractual commitments or violates the Supplier Code of Conduct, and report violations to Supply or Compliance & Ethics 7Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
An employee can seek assistance through any of the following options: • Department leadership • Human Resources • Compliance & Ethics • Ethics Help Line & Web Portal • Legal Department • Exelon Audit Services • Corporate and Information Security  Services Compliance & Ethics can be reached: • Directly at EthicsOffice2@Exeloncorp.com; or • Through the Exelon Ethics Help Line  Website An open culture that encourages us to voice our  opinions and concerns will help us capture great ideas and mitigate risks we face. When people  speak up, we innovate and improve, which drives  progress at Exelon. When people speak up to report improper behavior, we can resolve issues before harm is done or ensure prompt, effective remediation of any harm that has occurred. We must seek advice when we’re unsure about the proper course of action. We also are required  to speak up immediately if we see something that  violates – or could violate – the law or the Code.  If something does not feel right, we must take action to ensure that we maintain our standards  and serve our customers well. Resources If policies and procedures do not provide clear  direction, we should ask our managers or  Compliance & Ethics for guidance. There are many resources available when  employees have a question or need additional guidance, or when they need to raise a concern  or report a potential violation. Supervisors and  managers are the best initial resource. Compliance & Ethics Office  Compliance & Ethics is responsible for  administering Exelon’s Compliance & Ethics program. It is the primary resource for seeking  guidance about the Code and is responsible for  ensuring that all reports of potential violations are properly investigated and resolved. The Importance of Speaking Up and Seeking Help 8 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Exelon Help Line and Web Portal  The Ethics Help Line and web portal are available 24 hours a day, every day of the year. Both have  an anonymous reporting option. The Help Line is  a dedicated resource for asking compliance and ethics questions, raising compliance and ethics  concerns, and reporting suspected violations of  the law or the Code. No attempt is made to identify  individuals who choose to remain anonymous. All calls to the Help Line are answered by an  independent third-party vendor that offers  multilingual service. Caller ID is not used. A report  of each call is forwarded to Compliance & Ethics  for assessment and appropriate follow-up action. All reporters are issued a case number and a confidential Report Key and password that allows the reporter to follow up on a report, even if  the reporter has chosen to remain anonymous. During a follow up, a reporter can access  responses from Compliance & Ethics, including requests for additional information that may be  required to investigate. The Ethics Help Line (with anonymous reporting option) can be reached: By phone:  1-800-23ETHIC  (1-800-233-8442) Via web portal:  On your Exelon Connect home  page, click the Ethics Help Line tab located in the footer, and  follow the prompts, or enter the following address into  your browser: https://secure. ethicspoint.com/domain/media/ en/gui/71992/index.html 9Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Ethical, legal, and regulatory lapses can harm many Exelon stakeholders – including employees, customers, investors, and the communities we serve. They can also negatively impact our hard- earned reputation as an energy industry leader. We all have the responsibility to report promptly  – and in good faith – any activity that may violate the Code or applicable laws, rules, or regulations.  As noted in the Resources section, there are  multiple options for reporting possible violations. Note that these options do not restrict employees in the exercise of their rights to report a  concern to regulatory and law enforcement authorities including, but not limited to, the Equal Employment Opportunity Commission, Reporting Possible Violations the Federal Energy Regulatory Commission, the Department of Justice, and the Securities and Exchange Commission. All reports will be treated confidentially, to the fullest extent possible under the circumstances.  Employees must cooperate completely and honestly in any investigation. When an allegation  is substantiated Exelon will take appropriate  corrective action, including measures to prevent similar issues from occurring in the future. For more information, see Management Model Procedure LE-AC-204, Reporting  Potential Violations of the Code of Business  Conduct. 10 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Exelon will not tolerate retaliation against  anyone who, in good faith, raises a question or  concern about a potential violation of the Code  or potential non-compliance with applicable laws  or regulations. Retaliation in any form – threats, harassment, intimidation, violence, reassignment,  demotion, or firing – has no place in our organization. No Tolerance for Retaliation If any employee believes they have been subjected to retaliation for reporting a potential  violation or participating in an investigation, the employee should immediately contact one of the entities listed in the Resources section. Anyone  who threatens or engages in any act of retaliation  is subject to discipline, up to and including termination. 11Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
How we make decisions says as much about who  we are as a company as the decision itself. It is  important to make decisions we can be proud of. Making Ethical Decisions Could I defend my action in front of supervisors, fellow employees, the general public and my family? Does it conform to Exelon’s policies and procedures? Would I mind  my action being  reported in media channels? Is my action legal? Is my action  honest in every respect? Will my action  comply with the  intent and purpose  of the Code? Do I feel comfortable taking the action? Do I have all the information I need to make a good decision? If I am not  sure, have I  sought advice? Asking ourselves the following questions before  acting can help ensure we make the best choices for Exelon. 12 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024.

How We  Uphold the Code05 ©Exelon Corporation. 2024. All rights reserved. Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024

 
Exelon takes each report seriously, no matter how the report is received. Our procedures are  designed to promptly review and address each  issue. The Code requires us to participate completely  and honestly in any investigation conducted  by the company. Withholding information or being untruthful in an investigation can lead to  discipline, up to and including termination. Investigations Certification of Compliance For more information, see Corporate Procedure LE-AC-205, Investigating and  Resolving Alleged Violations of the Code of Business Conduct. All non-represented employees, officers, and directors of Exelon and its subsidiaries must complete a certification of compliance  questionnaire each year, which is reviewed and followed up on, as appropriate, by Compliance  & Ethics. Responses that identify potential violations of the law or Code will be appropriately investigated. ©Exelon Corporation. 2024. All rights reserved. 14 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024

 
Disciplinary Action The Code is important to the company and violations will not be tolerated. The Code must  be appropriately enforced, regardless of the seniority, role, or location of those involved in  misconduct. Exelon will consider matters involving potential criminal conduct for referral to law enforcement. Disciplinary action may be taken against any  Exelon employee, officer, or director who: • Authorizes or participates in actions that violate the Code or the law • Fails to report or discourage the reporting of a Code violation • Fails to cooperate with an investigation, conceals information, or otherwise intentionally obstructs an investigation by  the company • Retaliates or discriminates in any way against anyone who, in good faith, reports a suspected Code or legal violation or cooperates in an  investigation of a suspected violation • Fails to complete or falsely completes  a certification of compliance or related  questionnaire Discipline may include: • Reprimand or warning • Suspension or other administrative leave • Demotion • Reduction of bonus or incentive award • Required restitution for losses or damages • Termination of employment 15Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation.  2024.

A waiver of any provision of the Code will be made only in exceptional circumstances. Requests for waivers must be submitted to the Chief Compliance & Ethics Officer for review  and resolution. Any request for a waiver by any director or executive officer must be submitted to  Exelon’s Board of Directors or a Board committee.  In addition, any waiver of a provision in the Code for any director or executive officer must be  disclosed to shareholders.

Promoting a Safe and  Healthy Workplace We must maintain the highest standards of safety and reliability for our people,  our customers, and the public. How We Live Our Values ©Exelon Corporation.  2024. All rights reserved. 18 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024

 
“Safety first” requires us to: • Not engage in any behavior that poses a risk  to the safety of our coworkers, customers, or communities • Report to work fit for duty, take responsibility for our own safety, and look out for the safety of others • Know and follow all health and safety laws and regulations, as well as Exelon policies,  procedures, and established practices  • Eliminate potential hazards and continually improve safety performance in all areas of the company • Not take unnecessary risks on the job • Stop work immediately if it cannot be done  safely • Speak up immediately if we:  – See a health or safety hazard – Have a safety incident or near-miss – Observe threatening or violent behavior  – Observe any other behavior or event that could indicate a safety risk • Not possess any weapons, explosives, or  incapacitating devices while on duty, on company property or job sites, or while  in company vehicles (unless specifically authorized by company policies) What’s Expected We are dedicated to safety – this is an Exelon value. Our people do complicated work that can be dangerous if not performed in a safe manner. Maintaining the highest standards of safety and reliability helps keep our people, customers, and the public free from harm, our job sites secure,  and our productivity levels high. No job is so important and no schedule so urgent that we  can’t take the time to plan, perform, and supervise work in a safe and compliant manner. We seek to prevent all accidents and injuries, and Exelon will provide the resources needed to keep  our worksites safe and healthy. In turn, we are all  accountable for properly using these resources to  eliminate health and safety hazards. Our commitment to safety also includes protecting our employees from the risk of  violence in the workplace. Acts of violence,  threats and physical intimidation are strictly  prohibited at any Exelon work location. Why It’s Important 19Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
The Right Decisions A co-worker recently challenged our supervisor regarding a work plan for a new project, suggesting we consider a different approach because of concerns for the safety of the  employees performing the work. The suggested alternative would lengthen the time to complete the project and the supervisor rejected it without discussion. Should I pursue the issue further? Yes. Our commitment to employee safety must come first. You and your co-workers  may be able to get your supervisor to reconsider and discuss the safety issue. If you’re not comfortable having that conversation and the concerns persist, the situation must  be reported either up the management chain or to Compliance & Ethics, the Legal  Department, or Human Resources. A Q 20 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Maintaining a Drug-Free and Alcohol-Free Workplace How We Live Our Values We require a drug-free and alcohol-free workplace to support Exelon’s commitment to the safety and health of our people and the public. Safety is our priority. To do our work safely and  effectively, we must be able to think clearly and react quickly. The health, safety, and performance of everyone at Exelon demands that we are free from any substances – including drugs and alcohol – that could prevent us from doing our  jobs properly. Maintaining a drug- and alcohol-free workplace requires that we must: • Not use, possess, or be under the influence of  illicit drugs or alcohol while on duty, on company property or job sites, or in company vehicles • Follow all laws and regulations governing the use or possession of alcohol and drugs • Speak up immediately if we observe a colleague who may be under the influence of alcohol or drugs while at work • Use good judgment when alcohol is served at Exelon-sponsored events • Inform Exelon’s Occupational Health and  Safety Department if using, for medical reasons, any prescription or non-prescription drug that may impair alertness or judgmentWhy It’s Important What’s Expected For more information, see HR-AC-16, our Drug and Alcohol Policy. 21Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
The Right Decisions I recently noticed that a co-worker had alcohol on his breath while at work the last few mornings. Do I need to report it to someone? Yes. We can’t ignore potential violations of our Drug and Alcohol policies. Employees  under the influence of drugs or alcohol pose a safety risk to themselves, other  employees, and customers. We also want to encourage employees who may be suffering from substance abuse to use the resources provided by the company, such as the Employee Assistance Program (EAP). You must immediately report your observations to your supervisor or, if that is uncomfortable or impractical, to Human  Resources or Compliance & Ethics. A Q 22 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation.  2024. All rights reserved.

 
Living Diversity, Equity, and Inclusion How We Live Our Values At Exelon, we value our differences in background, skills, perspectives, and thinking.  We must make the most of everyone’s contribution to collaborate, innovate and  perform to our full potential. Exelon operates in a world that’s extremely diverse. Valuing individual differences in race,  color, national origin, ethnicity, gender, sexual  orientation, gender identity, disability, religious affiliation, experience, and thought makes us a  stronger, more successful organization. When we’re inclusive, we all contribute to solving  problems, overcoming challenges, and achieving  our vision of performance that drives progress. Diversity, Equity, and Inclusion at Exelon  strengthen us because they: • Foster an environment of mutual respect and  trust, in which each of us has the opportunity to grow and contribute • Enable us to attract, retain, and develop  colleagues who will best serve and represent  our customers, shareholders, partners, and communities • Provide different viewpoints that promote  innovation, drive powerful outcomes, and  ultimately make the company more successful We must: • Welcome and respect people with different perspectives, backgrounds, and traits • Evaluate individuals based on qualifications and demonstrated skills and achievements  without regard to personal characteristics,  including race, color, national origin, ethnicity,  gender, sexual orientation, gender identity, disability, or religious affiliation • Consider a diverse range of candidates in hiring, promotion, and other employment  decisions • Promote communication that is open, direct, honest, and respectful For more information, see our Diversity, Equity & Inclusion page on Exelon Connect  and Diversity & Inclusion Annual Report. Why It’s Important What’s Expected 23Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
The Right Decisions We are looking for a new technician at one of our facilities. One of the applicants is  missing a limb. He has a prosthetic and has the right training, but some people on the  hiring team have questioned whether his disability will limit his ability to complete his job duties in an effective and timely manner. How should this situation be handled? We succeed as an inclusive and diverse team. Basing a hiring decision in whole or in part on an applicant’s disability may violate the law. An applicant with a disability  should not be excluded from consideration based on assumptions or misperceptions.  Talent Acquisition, Human Resources, Occupational Health and Safety, and the Legal Department should be consulted so they can work collaboratively with management and the applicant to determine whether the applicant’s disability restricts his ability to perform the essential functions of his job and, if so, whether reasonable accommodations exist that will permit him to perform those essential functions. The fact that a reasonable accommodation may be required should not affect our evaluation  of his candidacy. If this candidate can perform all the essential functions of the position  with reasonable accommodation, hiring him offers the benefits that a different perspective and experience will bring to the team. A Q Calvin Butler Incorporating diverse perspectives into our thinking leads to greater innovation, increased employee  engagement, and better solutions to take advantage of opportunities  and overcome challenges. 24 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation.  2024.

Promoting a Respectful Workplace How We Live Our Values At Exelon, we thrive by treating each other with respect, fairness, and dignity. Our people have the right to work in an  atmosphere free from harassment. A respectful  workplace allows us to focus on what’s important: collaborating with each other to provide reliable,  clean, and affordable energy. The Code prohibits harassment in connection with any interaction with coworkers or customers  or any time we are representing the company in any way. Harassment also violates our values and  often the law – and it won’t be tolerated. A respectful workplace requires that we: • Deal with others in a considerate, courteous,  and respectful manner For more information, see HR-AC-72, our Policy Against Discrimination, Harassment,  and Retaliation, and HR-AC-73, our Policy Against Sexual Harassment. Why It’s Important What’s Expected • Think about how our actions and comments  might be received by others before we act or  speak • Not make – or tolerate – comments, insults,  jokes, or slurs with sexual, racial, gender, or  ethnic innuendo • Not engage in conduct, whether verbal or  physical conduct that another person would reasonably find threatening or humiliating • Not display or share images that contain  stereotypes or insults based on race, color, religion, sex, age, or disability • Provide a work environment free of unwelcome sexual advances and requests for sexual favors, and not engage in any other unwelcome verbal or physical conduct of a sexual nature toward coworkers, customers, or  others while representing the company • Report harassment we experience or observe • Not retaliate against anyone who, in good faith, reports potential harassment or other misconduct 25Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024.

The Right Decisions After completing a large project, our team celebrated with a company-sponsored dinner at a local restaurant. After several drinks, one of my co-workers told several sexually  suggestive jokes and made a similarly themed comment about one of our female co-workers who was present, but out of earshot. Several other employees looked uncomfortable, but no one said anything. Shortly afterward, I noticed one female co- worker leave the restaurant abruptly. What should I do? You should speak up. If you are comfortable doing so, tell your co-worker that the jokes and comments are unwelcome and inappropriate. Whether you address it directly or not, you must report the incident to your supervisor, HR, and/or Compliance &  Ethics. Although the dinner was off company premises, it was a work-related event and Exelon’s expectations regarding values and acceptable behavior apply. Fostering a culture of trust, collaboration, and performance means that no employee should be  made to feel uncomfortable, even in a more informal “social” setting with co-workers.

Avoiding Conflicts  of Interest We must make decisions and act in the  best interests of Exelon, not allowing our  personal interests to get in the way of what’s right for our business, customers, or shareholders.  How We Live Our Values ©Exelon Corporation.  2024. All rights reserved. 28 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024

 
To avoid conflicts of interest or the appareance of a conflict you should: • Not participate in any activity, interest, or association that could compromise your individual judgment or prevent you from acting in the best interests of the company • Avoid actions that could cause an uninvolved  observer to reasonably question your  objectivity • Seek guidance from a manager or the  Compliance & Ethics Office whenever  there is a question concerning an actual or potential conflict of interest • Promptly disclose all potential conflicts to  Compliance & Ethics • Remove yourself from the decision-making  process in any situation that might present  even the appearance of a conflict of interest What’s Expected Conflict of Interest Quick Test If I take this course of action: 1. Will I feel obligated to someone else? 2. Am I acting inconsistently with Exelon’s interests? 3. Could my independent judgment be compromised? 4. Could an uninvolved observer reasonably question my  objectivity? If you answer “yes” to any of these questions, a real or perceived conflict of interest may exist.  Immediately seek guidance from a manager or Compliance & Ethics. With every business decision and choice that we make, we have an impact on the performance and reputation of Exelon. Our decisions must be based on the facts and our  best judgment, while being mindful of our values and what’s best for the company. Allowing personal interests, relationships, or activities outside of work to interfere with our jobs or our ability to make objective business decisions for the good of Exelon is a conflict of interest. Such conflicts must be avoided because they can harm our effectiveness as well as our reputation for integrity. Even the appearance of a conflict of interest can make others think we are acting improperly.  Many conflicts of interest can be avoided or  addressed if promptly disclosed and properly managed. This section provides guidance  on some of the more common conflicts of  interest, but it cannot cover every situation we may face. Why It’s Important 29Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation.  2024. All rights reserved.

 
To avoid conflicts of interest or the appearance of a conflict, we must: • Make decisions objectively, without favoritism and in the best interest of Exelon • Promptly disclose to Compliance &  Ethics or Human Resources any personal  relationships that create or appear to  create a conflict of interest  • Not manage any business relationship  if the business partner employs someone with whom we have a close personal or  family relationship • Recuse ourselves from employment  decisions (including interviewing, hiring,  promoting, or disciplining) that involve  anyone with whom we have a close personal or family relationship • Not supervise, directly or indirectly,  anyone with whom we have a close personal or family relationship We must avoid conflicts of interest by: • Ensuring that our own investments and business relationships do not conflict with  our obligation to act in the best interests of Exelon • Promptly disclosing to Compliance & Ethics  any investments or business or personal relationships that might create, or appear to create, a conflict of interest • Disclosing any material financial interest in any organization that does business, seeks  to do business, or competes with Exelon to Compliance & Ethics to determine whether a potential conflict of interest can be  appropriately managed What does “material  financial interest” mean? “Material financial interest” means having any  financial involvement or ownership interest that might influence or reasonably be thought by  others to influence an employee’s judgment or  action in the conduct of Exelon’s business. You should consult Compliance & Ethics for guidance regarding whether specific financial interests are material. Personal Relationships Personal relationships with family members,  close friends, or romantic partners must not impact, or even appear to impact, our judgment and decision making for Exelon. Personal or Family Financial Interests Considerations of personal finances (or those of  family and friends) must not impair our ability  to make objective decisions on behalf of and in the best interests of the company. This may include investment in, or ownership of, an Exelon competitor, supplier, contractor, or partner. 30 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation.  2024. All rights reserved.

 
Gifts and Business Entertainment To maintain integrity in our business relationships,  you must not offer or accept a gift, entertainment,  or anything of value that is intended to influence a business decision or official action relating to  Exelon or might be perceived that way by others. Avoid conflicts of interest in business relationships by recognizing your obligation to: • Not offer or accept any gift of more than modest value • Not accept any monetary gifts, such as  cash, gift cards or personal discounts • Ensure that all business entertainment has a legitimate business purpose • Decline lavish or extravagant gifts or offers  of entertainment and explain that company policy prohibits accepting them (see  examples below) • Decline offers of business entertainment  from any third party where significant decisions about the third party are pending (e.g., a vendor is on a Supplier Performance  Improvement Plan or engaged in a significant dispute with Exelon or there is a pending business transaction of particular  significance to Exelon or the third party) • Obtain prior guidance from Compliance & Ethics if there is any question whether it is appropriate to accept a particular gift or  offer of business entertainment. • Accurately account for any gifts or entertainment given to third parties in expense records • Consider the nature of the event and  consult Compliance & Ethics before  accepting offers of travel or lodging from a third-party • Ensure that any offer or gift of anything of value to a government official or employee complies with Exelon’s Interactions with Public Officials policy, LE-AC-POL8. If there  is any question whether a gift, offer of entertainment, or anything else of value may be offered or provided consistent with this policy, seek advice and advance  approval from Compliance & Ethics The Right Decisions I have been working with a certain vendor for years. I know the owners and most of their  employees pretty well. I am often  asked by others at Exelon for input on the vendor’s performance, although I don’t have direct involvement in payment issues or renewal decisions. During the holidays, they usually send me a gift basket of food that I set out  for my team to share. This year,  the vendor included a $50 gift card, sent to me personally, with a nice note. I am certain the gift  card won’t influence my treatment of the vendor and I don’t want to insult them. Can I keep the gift  card? No. A gift card for any amount is no different from cash and accepting  it sends the wrong message, even if the sender is well-intentioned. All cash and cash equivalents received from third parties must  be declined. You should return it

with a polite note explaining that company policy prevents you from accepting. A Q 31Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Here are some examples of generally acceptable gifts and business entertainment, as well as some examples of gifts and entertainment that are generally unacceptable and must be declined or reviewed by management and Compliance & Ethics to  determine if the circumstances allow for acceptance: Generally Acceptable Entertainment • Infrequent meals of reasonable value at business-appropriate locations • Providing third parties with occasional meals, entertainment, refreshments or incidental hospitality Gifts • Mementos, advertising novelties and souvenirs, and promotional or logoed items of modest value • Small personal gifts or expressions of  gratitude, such as flowers Educational and Training Programs • Participation in routine training and  professional development opportunities  offered by vendors, such as seminars  and panel presentations, that do not involve lavish meals or entertainment Generally Unacceptable Entertainment • Tickets to a playoff game, championship, or other high profile sporting event (for  example, the Super Bowl, the Stanley Cup Finals, the World Series, the World Cup, etc.) • Any entertainment offered by a supplier if significant decisions about the supplier are pending and the recipient will play a direct or indirect role in that  decision • All-expenses-paid trips sponsored by a  supplier • Lavish entertainment or meals at expensive restaurants • Visiting an adult entertainment venue or other questionable locale • Frequent meals and entertainment from a continuing business supplier Gifts • Cash, gift certificates, or cash equivalents • Personal discounts or loans • Lavish or extravagant personal gifts What does "lavish" or "extravagant" mean? Whether a gift or offer of entertainment  is "lavish” or “extravagant" is a common-  sense determination of reasonableness based on all the circumstances. If you have any question at all about whether it is appropriate to accept a particular gift or  offer of entertainment, you should consult  Compliance & Ethics. 32 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Outside Employment  and Other Activities Exelon encourages our people to lead full and  productive lives outside of work. While at work, we must give our best effort every day, not allowing outside jobs or other activities to hinder  our contributions to Exelon and our customers. Outside activities – such as community work or serving on the board of a non-profit, or on an educational or residential board – are encouraged  as long as they do not interfere with our ability to  fulfill our Exelon responsibilities. Corporate Opportunities We must always put Exelon’s interests ahead of our own. Any business opportunities we discover, through our work or the use of company property  or information, belong to Exelon and must not be  used for our personal benefit. To avoid conflicts of interest we must: • Disclose and obtain prior approval for all outside employment or consulting opportunities (even short-term or hourly consulting engagements) • Ensure that outside activities do not interfere or create conflicts of interest with our Exelon job responsibilities or performance • Obtain approval from the Office of  Corporate Governance before serving on any board or advisory board of any for-profit organization • Not conduct outside business, political campaigns or other similar activities while working on company time • Not use Exelon resources to conduct activities unrelated to company business • Not work for a competitor, supplier, or other entity likely to do business with the  company To avoid conflicts of interest we must: • Not take for ourselves opportunities discovered through the use of company  property, company information, or our  position with the company • Not compete against Exelon or assist others in doing so 33Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation.  2024. All rights reserved.

 
Creating, Maintaining, and Disclosing Accurate Books and Records We must maintain complete and accurate records to make responsible business decisions and provide truthful and timely information to Exelon shareholders, investors, regulators, and other stakeholders. How We Live Our Values Business and financial records are essential  to our business operations. Exelon relies on the integrity and accuracy of these records to make strategic decisions. Similarly, investors, government agencies, regulators, and others rely on the integrity and accuracy of our records and disclosures.. Each of us is responsible for the accuracy of all the records we generate and data we input –  from individual timecards to corporate balance  sheets to equipment maintenance records.  Accurate and transparent record keeping protects our reputation, promotes organizational efficiency and safety, and helps us meet our legal  and regulatory obligations. It’s also essential in  helping our business better serve our customers. Creating and maintaining accurate books and records and ensuring accurate disclosures  requires that we: • Follow generally accepted accounting  principles and all procedures and guidelines in  our internal control systems • Not keep off-the-books accounts or false or incomplete records Why It’s Important What’s Expected • Not make an entry in any record that misrepresents, conceals, or disguises the true nature of any transaction, event, or condition • Record all business transactions, events, and conditions accurately, completely, and in a timely fashion • Ensure there is clear, complete, fair, and  accurate reporting of financial and non  financial information pertaining to business transactions • Follow all delegation of authority and  segregation of duties requirements established by the company involving the authorization,  creation, approval, and reconciliation of transactions • Provide receipts and back-up documentation when required • Not mislead or misinform anyone about our business operations or finances • Immediately report any requests to manipulate  accounts, books and records, or financial reports, and any suspected misconduct regarding accounting, internal controls, or  auditing matters to Compliance & Ethics,  Exelon Audit Services, or the Legal Department • Report to Exelon Audit Services any accounting or internal control deficiencies that could adversely affect Exelon’s ability to accurately record, process, or report financial or operations data 34 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Managing Our Records Appropriately How We Live Our Values We must accurately manage our records to protect Exelon’s proprietary and confidential information and meet our legal and regulatory obligations. Proper records management is essential to the vital flow of information within Exelon. It also reduces risks associated with outdated information and helps us meet our legal obligations and respond appropriately in legal and regulatory proceedings. Why It’s Important Proper records management  requires that we: • Maintain, retain, and dispose of business  records in accordance with Exelon’s Records Management Policy • Abide by all notices for the retention of documents issued by the Legal Department • Contact Compliance & Ethics or the Legal Department with any questions  about what to retain or discard, or for help understanding or complying with any record  hold or retention notice What’s Expected For more information see LE-AC-4, our  Corporate Policy on Records and Information Management, Retention and Disposition, and LE-AC-401, our Corporate Procedure on Records and Information Management, Retention and Disposition. 35Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Company records can include: • Communications in any form or media • Policies and procedures • Purchase orders and invoices • Contracts  • Reports, memos, analyses, maps, schedules, tables, presentations, and financial models  • Personnel files  • Production reports Company records come in all formats and media, including: • Paper documents, including correspondence, engineering drawings,  architectural plans, charts, records, sketches, and maps  • Photographs, prints, and electronic  media files  • Electronic records, including databases,  email, chat and text messages and  other forms of electronic communication,  and documents such as spreadsheets,  presentation decks, and written materials • Audio and video recordings, including voice mail • Microfilm, microfiche, aperture cards, and  other microform media Note that whether something is a company  record is determined by its content, not  where and how it is stored. 36 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Protecting Company Assets How We Live Our Values We must protect Exelon’s assets and use them responsibly so we can better serve our customers and thrive in a dynamic industry. Exelon’s assets are essential to running our  company efficiently, effectively, and profitably. They are the resources we use to drive progress. While our responsibilities will vary depending on  the type of asset and our individual roles within Exelon, one thing remains the same – each of us is responsible for protecting company assets. • Physical assets include anything tangible that  we use to conduct our business, from computers, office supplies, and furnishings,  to transmission lines, substations, and natural gas mains. The land, buildings, vehicles, and inventory Exelon owns or has interests in are also physical assets. • Information assets include any data relating to Exelon’s business, no matter how it is created, distributed, used, or stored. This includes computer software and data in our files and on our servers. • Intangible assets include Exelon’s ideas,  inventions, improvements, intellectual property, designs, copyrights, licenses,  trademarks, patents, and trade secrets. This includes our own work product and on-the-job  innovations and discoveries. • Financial assets include money and anything that can be converted to money, such as stocks, bonds, loans, and deposits. Why It’s Important To protect Exelon’s assets, we must: • Use them prudently, carefully, and efficiently • Take reasonable steps to protect company assets, ensuring they are not damaged, abused,  destroyed, wasted, lost, or stolen • Use company assets only for Exelon business purposes, regardless of condition or value, except for incidental personal use of  computers and mobile devices (see page 40) • Not sell, lend, borrow, give away, or dispose of company assets without proper authorization • Promptly report any abuse or misuse • Bring any on-the-job discoveries or innovations related to Exelon’s business to the company’s attention • Not use proprietary information acquired on the job for personal gain or any other purpose not in furtherance of our job duties What’s Expected 37Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Protecting Our Confidential Information Business information is a critical Exelon asset. We must closely protect the company’s confidential information and intellectual property against  unauthorized disclosure and misuse, which could limit our growth and threaten our ability to  compete in the future. Protecting Exelon’s confidential information  requires that we: • Do not post confidential information on any social media sites • Do not work with or discuss confidential  information in public areas, such as airplanes, elevators, or restaurants, where  your conversations may be overheard or confidential information may be viewed by others • Not leave confidential information where  others could access it • Share sensitive information only with authorized co-workers or business partners who have a legitimate need to know For more information, see our Corporate  Procedure LE-AC-301, Protecting Exelon  Information and related procedures and  policies. • Do not divulge confidential information to persons outside of the Exelon business, except where such disclosure is  appropriately authorized, legally mandated, or done in accordance with a  confidentiality and non-disclosure  agreement • Continue to protect Exelon confidential  information, including our own work product, even if we leave the company • Protect our customers’ and suppliers’ confidential information as we would protect Exelon’s confidential information,  and consistent with any additional legal  and contractual requirements. • Immediately report any unauthorized disclosure or loss of confidential information to Corporate Security or  Compliance & Ethics 38 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
The Right Decisions A peer utility asked for copies of specific Management Model policies and procedures. Can I share them with another company? There is tension between the company’s inclination to share best practices for the  benefit of the industry – particularly through industry groups such as EEI, EPRI, or AGA – and our need to control Exelon’s proprietary information. In most situations, the right balance is to not hand over our policies and procedures, but rather to provide  the other company’s personnel with a verbal overview. Contact your management  team, the Legal Department or the functional area that has governance over specific documents with questions. A Q What are some examples of confidential information? • Business plans, reports, and projections  (including estimates or reports of production, reserves, and resources) • Company policies and procedures that are not publicly available • Marketing and sales strategies • Patents, trademarks, and other intellectual  property • Inventions, ideas, proprietary information, and trade secrets  • Estimates and non-public reports of resources, reserves, exploration results and productivity • Applications, proposals, and contracts • Unpublished financial information • Confidential information belonging to other parties with which we do business, such as prices charged or proposed to Exelon for goods and/or  services • Technological developments and designs • Computer software • Customer or supplier lists • Customer information 39Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Using Information and Communications Systems  Responsibly Exelon’s information and communications systems are critical to providing reliable, clean,  and affordable energy. We all must be prudent  and responsible in our use of these systems. Our information and communications equipment and systems include mobile devices, computers, and networks. They are the property of Exelon, as are the contents of communications shared over these systems, such as email, voicemail, social  media posts, instant messages, recordings, texts, and any other electronic messages. Incidental personal use of these resources is  permitted if it’s reasonable and does not interfere  with work responsibilities or expose Exelon to  potential liability. What is “acceptable use”? Incidental, infrequent, and reasonable personal  use of Exelon mobile devices, computers and related resources is acceptable. Limited personal use of the company’s electronic information  assets is permitted if it is not detrimental to the  productivity of the employee or co-workers,  does not cause liability or additional costs to  the company, and is not otherwise prohibited by management. Responsible use of Exelon’s information and  communications systems requires that we: • Grant access only to authorized individuals • Do not share or use unauthorized login credentials for accessing company systems and networks  • Take precautions to ensure company systems and devices are not compromised  by malicious electronic threats, such as  viruses and phishing schemes • Acknowledge that there is no expectation of privacy when using company-provided  information technology and equipment • Take the same care composing any electronic message that we would when writing a letter on company letterhead • Not use Exelon information, communications systems, or equipment for illegal or unethical activities, such as  viewing or sending content that is  pornographic, obscene, sexually oriented,  harassing, violent, discriminatory, likely to incite hatred or otherwise offensive • Substantive written business communications should be conducted on Exelon networks and communication platforms, not on personal accounts, absent special circumstances For more information regarding acceptable use of Exelon systems, including the company  guidelines for text communication, see our Corporate Procedure SY-AC-6, Acceptable Use Policy. 40 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Avoiding Insider Trading How We Live Our Values Exelon supports fair and open markets for buying and selling securities. Insider trading  is illegal and distorts financial markets. Insider trading is illegal and damages the trust we  have with our investors, the government, and the  marketplace. Insider trading is committed when people who have material nonpublic information trade in shares or other securities of a company before the information becomes available to the public. Because of our roles at Exelon, many of us have that kind of “inside information” – information  that is not known to the public that might be  important to someone considering buying or  selling shares in Exelon or another company. Why It’s Important To avoid insider trading, we must: • Not buy, sell, or trade the stock or other securities of Exelon or any other company while we have inside information What’s Expected • Prevent inside information from being disclosed to people outside Exelon. This means: – Keep it secure – whether it’s a physical lock on a file drawer or a password on a laptop  or cell phone – Share it only with those within the company who have a legitimate business need  to know – Don’t share it with family or friends – Never discuss it in public or on social media • Abstain from making buy or sell recommendations to anyone else while in  possession of inside information • Not engage in “short sales” or trading in  market options such as puts or calls on Exelon  securities • Immediately report to Compliance & Ethics or the Legal Department any inside information that has been mistakenly provided to  unauthorized individuals For more information, see our Corporate Procedure LE-AC-202, Insider Trading  Compliance. 41Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
The Right Decisions I was part of a team that recently  completed a very significant transaction. As a result, I had  access to communications that indicated company earnings would exceed expectations this  quarter. I was planning to make  some adjustments to my 401(k)  account, including an increase in the percentage of company stock included in my contribution, before I saw the earnings communication. Can I still make that adjustment? No, not until the earnings results become public. Even when information does not actually  influence you, trading after the receipt of insider information and  prior to that information becoming public is prohibited by law. This might result in criminal charges  and civil penalties against you. A Q Examples of inside information include: • Unreleased company financial results and dividends • Detailed business plans or marketing strategies • Anticipated mergers, acquisitions, divestitures or joint ventures • A significant change in corporate  strategy • Significant management changes • Important developments in legal  proceedings 42 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024.

Competing  with Integrity At Exelon, we must conduct business  honestly, fairly and lawfully. We must compete vigorously for business opportunities, distinguishing ourselves  through integrity, superior performance and value. How We Live Our Values ©Exelon Corporation. 2024. All rights reserved. 44 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024

 
Healthy competition is good for our customers  and the communities we serve. Our commitment to fair competition and responsible third- party sourcing policies and practices helps drive progress and value for our customers, communities and shareholders. We must avoid  even the appearance of restraining trade or reducing competition. It’s therefore essential that we follow all applicable laws that govern the way companies compete, wherever we do business. These laws are complex and the consequences of violations can be serious for the individuals and companies involved. In our dealings with competitors, we  must avoid even the appearance of restraining trade or reducing competition. Why It’s Important As regulated utilities, Exelon and its operating  companies have few direct “competitors.”  However, Exelon and its affiliates participate in many competitive markets including but not limited to markets for labor, materials, and  services. Exelon also participates in competitive bidding processes, such as bidding for the right to construct certain transmission facilities. When participating in competitive markets, we must: • Comply with antitrust laws and similar laws in  What’s Expected any jurisdiction where we conduct business • Ensure Exelon’s business activities do not (and do not appear to) fix prices or costs between  competitors, restrict output, divide markets or force a competitor out of business  • Protect from improper disclosure confidential  information regarding pricing (past, present,  or future), terms and conditions of business,  contracts and bids, markets and territories, customers, costs, production, and distribution • Not enter into agreements that improperly  restrain competition for labor • Not disclose one bidder’s confidential  information to another bidder or otherwise undermine the integrity of bidding processes  that we run or compete in • Remove ourselves from any conversation that could restrain trade or reduce competition, indicate our reason for doing so, and  immediately report the matter to the Legal Department or Compliance & Ethics • Always remain aware of how conversations  with peer utilities may be perceived, and avoid  the appearance of misconduct When dealing with customers, fair competition  requires that we: • Describe what we do and sell honestly and  accurately • Not make false claims or spread false or misleading information about our competitors or their services • Not interfere with a customer’s or competitor's  existing business contracts 45Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Promoting Fair Purchasing Practices We must select suppliers fairly and  objectively to ensure the best value for  Exelon while protecting our reputation  and supporting the diverse communities we serve. How We Live Our Values Our suppliers often are an extension of Exelon.  We count on them to help us deliver the best service for our customers. We work with a diverse group of suppliers and contractors who share our  commitment to the highest standards in quality, price, service, reliability, availability, technical  excellence, and delivery. Why It’s Important Those involved in purchasing and relationship  management with suppliers have the  responsibility to: • Make procurement decisions with integrity, based on objective, fair and reasonable criteria • Follow Exelon’s third-party sourcing policies,  procedures, and processes and properly  document and seek approval for any  exceptions What’s Expected • Ensure we have appropriate and properly documented justification for any sole source  procurement • Avoid frequent or excessive business  entertaining with any supplier • Treat all suppliers professionally, ethically, and fairly – regardless of the value of the  transaction or the length of the relationship • Conduct Exelon business in good faith and resolve disputes with suppliers quickly and equitably • Administer contracts to ensure Exelon receives the materials and/or services in full  compliance with the contract terms For more information, see, for example, Corporate Policies and Procedures  SM-AC-POL1-001, Exelon Spending Policy and  Authorization to Contract with Suppliers; SM- AC-400, Materials and Services Procurement  Procedure; PC-EU-1035, Contractor Award  Procedure; SM-AC-4011, Single Source Procedure; LE-AC-11, Delegation of  Authority Policy  46 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024.

Gathering Business Intelligence As we evolve our business, we constantly monitor the competitive landscape and  analyze industry trends. This allows us  to anticipate and respond to customer demands for clean, affordable energy and the delivery of services. We gather  business intelligence properly and  legally, and do not solicit or accept other companies’ trade secrets or other  proprietary or confidential information. Below is a list that includes some generally acceptable and generally unacceptable  sources of competitive intelligence: If there is ever a doubt about how we are gathering business information, or contact the Legal  Department or Compliance & Ethics for guidance. Generally Acceptable • Public web sites and social media • Newspapers and trade journals • Public financial filings • Publicly available industry analyst reports • Marketing materials • Third-party market research and analysis • Governmental agency reports Generally Unacceptable • Emails intended for others • Proposals • Price sheets • Process documents • Business plans • Found apparent confidential documents • Non-public due diligence associated with  M&A activity and other transactions • Materials governed by a confidentiality agreement 47Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation.  2024. All rights reserved.

 
The Right Decisions I work in project management. A supplier who is working on a current project asked me for some detailed information about a new project that just went out for bid. What should I do? While the supplier’s intent may be innocent, informally providing any information about the new project might provide that firm with an advantage over other bidders. You should not provide any information about the new project, and should direct the supplier to the proper channel for obtaining information (in this case, the formal Request for Proposal information sharing protocols) and advise that they follow the process. Additionally, you should notify your manager, Compliance & Ethics, or the Legal Department that you received this request from the supplier. A Q 48 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Ensuring Appropriate  Affiliate Interactions Laws and regulations require separation  between utility transmission operations  and their affiliates. How We Live Our Values Regulatory authorities governing the energy industry have established affiliate rules to  safeguard the fair treatment of all utility rate  payers. These rules guard against unfair activities, such as inappropriately sharing information or  allocating costs incurred by affiliates to a utility. Where applicable, we must comply with all  affiliate regulations, including: • FERC Standards of Conduct • Pennsylvania Code of Conduct • Illinois Affiliate Non-Discrimination Rules  • New Jersey Affiliate Standards Rules • Maryland Electric and Gas Companies –  Affiliate Regulations • Delaware Code of Conduct Governing  Regulated Utility Activities and Competitive  Activities • District of Columbia Affiliate Code of Conduct Why It’s Important Appropriate affiliate interactions require that we  must: • Properly charge or allocate costs between  the regulated and other business functions of utilities and between utilities and their non- utility affiliates, as well as verifying that costs  have been correctly allocated • Not provide transmission function information to Exelon marketing function personnel • Not share non-public information about  a utility's market, its customers, or its transmission and distribution systems to any  third parties on an unduly preferential basis • Not share utility customer information across Exelon utilities, without consent of the customer What’s Expected 49Code of Business Conduct Approved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024. All rights reserved.

 
Trading Energy Responsibly We conduct and report on our electric power and gas procurement activities in a transparent and ethical manner, complying fully with all applicable laws and regulations. How We Live Our Values The buying and selling of wholesale energy are governed by Federal Energy Regulatory  Commission (FERC) rules and orders, while state  laws, regulations and utility commission orders govern the provision of retail electric and gas service to customers. Ensuring the integrity of our energy procurement activities protects the company from violating these rules, helps to  ensure such activities are conducted fairly by all participants in the marketplace and protects the  company against cost disallowances. Why It’s Important Responsible energy procurement practices  require that we must: • Satisfy statutory and regulatory obligations to provide standard offer service (SOS), to function as the electric or gas service provider of last resort (POLR) or gas supplier of last resort (SOLR), to meet the needs of our customers What’s Expected • Optimize energy procurements not utilized to meet POLR or SOLR responsibilities to benefit customers and shareholders, where applicable • Responsibly execute regulatorily-approved energy commodity supply programs for the benefit of customers and shareholders • Follow statutory, FERC and state utility  commission-sanctioned frameworks, and structures that direct utilities on how to  procure energy for retail end use customers • Pursue transparent and reliable electric power supply and gas supply in full compliance with applicable statutory and regulatory mandates • Prepare and maintain accurate documentation  of all energy procurement transactions consistent with applicable laws and regulations 50 Code of Business ConductApproved by the Exelon Board of Directors: Effective February 15, 2024 ©Exelon Corporation. 2024.

OCG has established and maintains procedures for the approval of  transactions and maintains controls to ensure compliance with this Policy. These procedures  are communicated to all Tier 1 and Tier 2 Persons at the beginning of each Trading Window. Approval by OCG of any transaction does not relieve anyone of the responsibility for compliance with federal securities laws and does not constitute legal or investment  advice. 4.4.4 Broker Letters. Any Tier 2 Person who holds Exelon Securities in a private brokerage account  must enter into an agreement with his/her broker that (a) requires the broker to obtain authorization from OCG before executing any trade and (b) authorizes the broker to provide  immediate notice to OCG of all trades in Exelon Securities, and to confirm balances and provide other information as needed to OCG. 4.4.5 Rules Remain in Effect for 90 Days after Separation. Tier 2 Persons (and their Related  Persons) remain subject to pre-approval of trading for 90 days after ceasing to serve in such  role for any reason. However, in this case, the trading of Exelon Securities need not be limited  to the Trading Windows. The 90-day period will be measured from the date the person  officially terminates employment. (See Section 4.5.3 for related provision applicable to Section  16 Insiders.) 4.5 Additional Rules Applicable to Section 16 Insiders  4.5.1 Reporting Requirements. All Section 16 Insiders are required by federal securities laws to file reports with the SEC disclosing initial beneficial ownership of, and any

transactions in Exelon Securities. OCG maintains procedures to assist Section 16 Insiders with compliance with this requirement and to facilitate the reporting obligations of these individuals.

 
Insider Trading Compliance LE-AC-202 4.5.2 Prohibition Against Trading During Benefit Plan Blackout Periods. During a Benefit Plan  Blackout Period, Section 16 Insiders may not buy or sell any Exelon common stock in any other account or in any other Benefit Plan. Any profit obtained by a Section 16 Insider from  trades during a Benefit Plan Blackout Period must be returned to the Company. OCG maintains procedures for communicating to Section 16 Insiders about any Benefit Plan  Blackout Periods. 4.5.3 Rules Remain in Effect for Six Months after Separation. Certain reporting requirements under  federal securities laws remain in effect for Section 16 Insiders for six months after the termination of employment or cessation of serving in a Director or an Executive Officer role for any reason, therefore prior approval for trading also remains in effect for six months. However, trading of Exelon Securities need not be limited to Trading Windows. The six-month period will be measured from the date the person officially terminates employment.  4.6 10b5-1 Trading Plans 4.6.1 Trading Through Approved Trading Plans. The Company allows individuals to enter into pre- set Trading Plans designed to meet the requirements of the SEC’s Rule 10b5-1(c) pursuant to which trades in Exelon Securities may be executed.  Entry into a Trading Plan may only be made in good faith and during an open Trading Window and so long as the individual establishing the plan has no MNPI and receives pre-clearance from OCG. See Attachment 6.1 for additional details and requirements about the design, approval, and execution of such Trading Plans. 4.6.2 Multiple Plans Prohibited. Individuals may not have multiple Trading Plans in place at any one period of time; however, an individual may enter a new Trading Plan (subject to the same  timing and pre-clearance requirements set forth in Section 4.6.1) that will take effect after the expiration or termination of a then-effective Trading Plan. An Individual with a Trading Plan in effect may not buy or sell Exelon Securities outside of that Trading Plan until the expiration or  termination of that Trading Plan. 4.6.3 Single Trade Plans. In any twelve-month period, individuals are limited to one Trading Plan that is designed to effect an open market purchase or sale as a single transaction. 4.6.4 Amending Trading Plans. Trading Plans may not be amended; however, individuals may  terminate an existing Trading Plan in accordance with Section 4.6.5 and commence a new  Trading Plan subject to the same timing and pre-clearance requirements set forth in Section 4.6.1.  4.6.5 Terminating Trading Plans. Individuals may terminate an existing Trading Plan

prior to the  execution of the first trade under the Trading Plan by providing notice to OCG and the  executing broker prior to termination. * * *

 
Insider Trading Compliance LE-AC-202 ATTACHMENT DESIGN, APPROVAL AND EXECUTION OF TRADING PLANS DESIGNED TO COMPLY WITH THE  PROVISIONS OF SEC RULE 10b5-1  The procedures for establishing a 10b5-1 Trading Plans set forth below are supplementary to the provisions of LE-AC-202, Insider Trading Compliance Policy. Unless otherwise defined in these  procedures, defined terms have their meanings as set forth in the Insider Trading Compliance Policy. Plan Provider  • Exelon works with an equity administration vendor to make Trading Plans available to Exelon incentive plan participants.  • Individuals may use Trading Plans established by other financial advisors/brokers subject to approval by OCG.  Establishing a Plan  • Individuals wishing to enter a Trading Plan should contact Exelon’s equity administration vendor to discuss the design and parameters of the plan. • Trading Plans may only be entered into in good faith and during an open Trading Window when the individual has no MNPI. • Any Covered Person may adopt a Trading Plan. Trading Plans are strongly encouraged for  Section 16 Insiders wishing to engage in long-term trading to meet wealth management or  estate planning goals.  Plan Requirements and Approval • For Directors and Executive Officers, the first trade under a Trading Plan may not be executed until the later of (a) 90 days after adoption of the Trading Plan or (b) two business days  following the filing of the Form 10-Q or Form 10-K for the fiscal quarter in which the plan was adopted.  • For all other Covered Persons, the first trade under a Trading Plan may not be executed until 30  days after adoption of the Trading Plan. • The plan must specify an amount, price, and date of transaction(s). Subject to approval by the  broker that will execute the transaction, there is no minimum transaction size.  • Trades under a Trading Plan may occur at any time, including outside of an open Trading Window. • The terms of any Trading Plan are generally subject to approval by the broker that will execute the transactions.

(c) Evaluated the effectiveness of the registrant’s disclosure controls and procedures and presented in this report our conclusions about the effectiveness of the disclosure controls and procedures, as

5. The registrant’s other certifying officer and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the registrant’s auditors and the audit committee of the

registrant’s board of directors (or persons performing the equivalent functions):
(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant’s ability to

record, process, summarize and report financial information; and

(b) Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant’s internal control over financial reporting.

1  Exelon Corporation FINANCIAL RESTATEMENT COMPENSATION RECOUPMENT POLICY  Approved July 25, 2023  The Board of Directors (the “Board”) of Exelon Corporation (the “Company”) has adopted this Financial  Restatement Compensation Recoupment Policy (the “Policy”). This Policy provides for the recoupment of certain executive compensation in the event of an accounting restatement resulting from material noncompliance with  financial reporting requirements under U.S. federal securities laws in accordance with the terms and conditions set forth herein. This Policy is intended to comply with the requirements of Section 10D of the U.S. Securities  Exchange Act of 1934, as amended (the “Exchange Act”) and Section 5608 of the Nasdaq Listing Rules.  1. Definitions. For the purposes of this Policy, the following terms shall have the meanings set forth below.  a) “Committee” means the Talent Management and Compensation Committee of the Board or any successor committee thereof.  b) “Covered Compensation” means any Incentive-based Compensation “received” by a Covered Executive  during the applicable Recoupment Period; provided that:  (i) such Covered Compensation was received by such Covered Executive (A) after the Effective Date,  (B) after they commenced service as an Executive Officer and (C) while the Company had a class of securities publicly listed on a United States national securities exchange; and  (ii) such Covered Executive served as an Executive Officer at any time during the performance period  applicable to such Incentive-based Compensation. For purposes of this Policy, Incentive-based Compensation is “received” by a Covered Executive during  the fiscal period in which the Financial Reporting Measure applicable to such Incentive-based Compensation (or portion thereof) is attained, even if the payment or grant of such Incentive-based Compensation is made thereafter.  c) “Covered Executive” means any current or former Executive Officer.  d) “Effective Date” means December 1, 2023.  e) “Executive Officer” means those officers designated by the Committee as Executive Officers who are required to file forms with the SEC pursuant to Section 16(a) of the Securities Exchange Act of 1934, as  amended. f) “Financial Reporting Measure” means any (i) measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, (ii) stock price  measure or (iii) total shareholder return measure (and any measures that are derived wholly or in part from any measure referenced in clause (i), (ii) or (iii) above). For the avoidance of doubt, any such

measure  does not need to be presented within the Company’s financial statements or included in a filing with the U.S. Securities and Exchange Commission to constitute a Financial Reporting Measure.

2  g) “Financial Restatement” means a restatement of the Company’s financial statements due to the  Company’s material noncompliance with any financial reporting requirement under U.S. federal securities laws that is required in order to correct:  (i) an error in previously issued financial statements that is material to the previously issued financial statements; or  (ii) an error that would result in a material misstatement if (A) the error were corrected in the current period or (B) left uncorrected in the current period. For purposes of this Policy, a Financial Restatement shall not be deemed to occur in the event of a revision of the Company’s financial statements due to an out-of-period adjustment (i.e., when the error is immaterial to the previously issued financial statements and the correction of the error is also immaterial to the current period) or a retrospective (1) application of a change in accounting principles; (2) revision to reportable segment information due to a change in the structure of the Company’s internal organization; (3) reclassification due to a discontinued operation; (4) application of a change in reporting  entity, such as from a reorganization of entities under common control; or (5) revision for stock splits,  reverse stock splits, stock dividends or other changes in capital structure. h) “Incentive-based Compensation” means any compensation (including, for the avoidance of doubt, any  cash or equity or equity-based compensation, whether deferred or current) that is granted, earned and/or vested based wholly or in part upon the achievement of a Financial Reporting Measure. For purposes of this Policy, “Incentive-based Compensation” shall also be deemed to include any amounts which were  determined based on (or were otherwise calculated by reference to) Incentive-based Compensation as defined in the preceding sentence, including, without limitation, any amounts under any long-term disability, life insurance or supplemental retirement or severance plan or agreement or any notional account that is based on Incentive-based Compensation, as well as any earnings accrued thereon.  i) “Nasdaq” means the NASDAQ Global Select Market, or any successor thereof.  j) “Recoupment Period” means the three fiscal years completed immediately preceding the date of any  applicable Recoupment Trigger Date. Notwithstanding the foregoing, the Recoupment Period additionally includes any transition period (that results from a change in the Company’s fiscal year) within or immediately following those three completed fiscal years, provided that a transition period between the last day of the Company’s previous fiscal year end and the first day of its new fiscal year that comprises

a  period of nine (9) to twelve (12) months would be deemed a completed fiscal year. k) “Recoupment Trigger Date” means the earlier of (i) the date that the Board (or a committee thereof or  the officer(s) of the Company authorized to take such action if Board action is not required) concludes, or reasonably should have concluded, that the Company is required to prepare a Financial Restatement, and  (ii) the date on which a court, regulator or other legally authorized body directs the Company to prepare a Financial Restatement.

 
3  2. Recoupment of Erroneously Awarded Compensation.  a) In the event of a Financial Restatement, if the amount of any Covered Compensation received by a Covered Executive (the “Awarded Compensation”) exceeds the amount of such Covered Compensation that otherwise would have been received by such Covered Executive if calculated based on the Financial  Restatement (the “Adjusted Compensation”), the Company shall reasonably promptly recover from such  Covered Executive an amount equal to the excess of the Awarded Compensation over the Adjusted  Compensation, each calculated on a pre-tax basis (such excess amount, the “Erroneously Awarded Compensation”). b) If (i) the Financial Reporting Measure applicable to the relevant Covered Compensation is stock price or  total shareholder return (or any measure derived wholly or in part from either of such measures) and  (ii) the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in the Financial Restatement, then the amount of Erroneously Awarded Compensation shall be determined (on a pre-tax basis) based on the Company’s reasonable estimate of  the effect of the Financial Restatement on the Company’s stock price or total shareholder return (or the derivative measure thereof) upon which such Covered Compensation was received. c) For the avoidance of doubt, the Company’s obligation to recover Erroneously Awarded Compensation is  not dependent on (i) if or when the restated financial statements are filed or (ii) any fault of any Covered  Executive for the accounting errors or other actions leading to a Financial Restatement.  d) Notwithstanding anything to the contrary in Sections 2a) through c) hereof, the Company shall not be  required to recover any Erroneously Awarded Compensation if both (x) the conditions set forth in either of the following clauses (i) or (ii) are satisfied and (y) the Committee (or a majority of the independent  directors serving on the Board) has determined that recovery of the Erroneously Awarded Compensation  would be impracticable:  (i) the direct expense paid to a third party to assist in enforcing the recovery of the Erroneously  Awarded Compensation under this Policy would exceed the amount of such Erroneously Awarded Compensation to be recovered; provided that, before concluding that it would be impracticable  to recover any amount of Erroneously Awarded Compensation pursuant to this Section 2d), the Company shall have first made a reasonable attempt to recover such Erroneously Awarded Compensation, document such reasonable attempt(s) to make such recovery and provide that documentation to the

Nasdaq; (ii) recovery of the Erroneously Awarded Compensation would likely cause an otherwise tax-qualified  retirement plan, under which benefits are broadly available to employees of the Company, to fail  to meet the requirements of Sections 401(a)(13) or 411(a) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). e) The Company shall not indemnify any Covered Executive, directly or indirectly, for any losses that such  Covered Executive may incur in connection with the recovery of Erroneously Awarded Compensation  pursuant to this Policy, including through the payment of insurance premiums or gross-up payments. f) The Committee shall determine, in its sole discretion, the manner and timing in which any Erroneously  Awarded Compensation shall be recovered from a Covered Executive in accordance with applicable law,  including, without limitation, by (i) requiring reimbursement of Covered Compensation previously paid in

 
4  cash; (ii) seeking recovery of any gain realized on the vesting, exercise, settlement, sale, transfer or other  disposition of any equity or equity-based awards; (iii) offsetting the Erroneously Awarded Compensation  amount from any compensation otherwise owed by the Company or any of its affiliates to the Covered  Executive; (iv) cancelling outstanding vested or unvested equity or equity-based awards; and/or (v) taking any other remedial and recovery action permitted by applicable law. For the avoidance of doubt, except as set forth in Section 2(d), in no event may the Company accept an amount that is less than the amount of Erroneously Awarded Compensation; provided that, to the extent necessary to avoid any adverse tax consequences to the Covered Executive pursuant to Section 409A of the Code, any offsets against amounts under any nonqualified deferred compensation plans (as defined under Section 409A of the Code) shall be made in compliance with Section 409A of the Code. 3. Administration. This Policy shall be administered by the Committee. All decisions of the Committee shall be  final, conclusive, and binding upon the Company and the Covered Executives, their beneficiaries, executors, administrators, and any other legal representative. The Committee shall have full power and authority to (i)  administer and interpret this Policy; (ii) correct any defect, supply any omission and reconcile any inconsistency in this Policy; and (iii) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of this Policy and to comply with applicable  law (including Section 10D of the Exchange Act) and applicable stock market or exchange rules and regulations. Notwithstanding anything to the contrary contained herein, to the extent permitted by Section 10D of the Exchange Act and Section 5608 of the Nasdaq Listing Rules, the Board may, in its sole discretion,  at any time and from time to time, administer this Policy in the same manner as the Committee.  4. Amendment/Termination. Subject to Section 10D of the Exchange Act and Section 5608 of the Nasdaq Listing Rules, this Policy may be amended or terminated by the Committee at any time. To the extent that any  applicable law, or stock market or exchange rules or regulations require recovery of Erroneously Awarded Compensation in circumstances in addition to those specified herein, nothing in this Policy shall be deemed  to limit or restrict the right or obligation of the Company to recover Erroneously Awarded Compensation to  the fullest extent required by such applicable law, stock market or exchange rules and regulations. Unless otherwise

required by applicable law, this Policy shall no longer be effective from and after the date that the  Company no longer has a class of securities publicly listed on a United States national securities exchange. 5. Interpretation. Notwithstanding anything to the contrary herein, this Policy is intended to comply with the requirements of Section 10D of the Exchange Act and Section 5608 of the Nasdaq Listing Rules (and any applicable regulations, administrative interpretations or stock market or exchange rules and regulations  adopted in connection therewith). The provisions of this Policy shall be interpreted in a manner that satisfies such requirements and this Policy shall be operated accordingly. If any provision of this Policy would otherwise frustrate or conflict with this intent, the provision shall be interpreted and deemed amended so  as to avoid such conflict. 6. Other Compensation Clawback/Recoupment Rights. Any right of recoupment under this Policy is in addition to, and not in lieu of, any other remedies, rights or requirements with respect to the clawback or recoupment of any compensation that may be available to the Company pursuant to the terms of any other recoupment or clawback policy of the Company (or any of its affiliates) that may be in effect from time to time, any provisions in any employment agreement, offer letter, equity plan, equity award agreement or similar plan or agreement, and any other legal remedies available to the Company, as well as applicable law, stock  market or exchange rules, listing standards or regulations; provided, however, that any amounts recouped or clawed back under any other policy that would be recoupable under this Policy shall count toward any  required clawback or recoupment under this Policy and vice versa.

 
5  7. Exempt Compensation. Notwithstanding anything to the contrary herein, the Company has no obligation to  seek recoupment of amounts paid to a Covered Executive which are granted, vested, or earned based solely  upon the occurrence or non-occurrence of nonfinancial events. Such exempt compensation includes, without limitation, base salary, time-vesting awards, compensation awarded on the basis of the  achievement of metrics that are not Financial Reporting Measures or compensation awarded solely at the  discretion of the Committee or the Board, provided that such amounts are in no way contingent on, and were not in any way granted on the basis of, the achievement of any Financial Reporting Measure performance goal. 8. Miscellaneous. a) Any applicable award agreement or other document setting forth the terms and conditions of any  compensation covered by this Policy shall be deemed to include the restrictions imposed herein and  incorporate this Policy by reference and, in the event of any inconsistency, the terms of this Policy will govern. For the avoidance of doubt, this Policy applies to all compensation that is received on or after the Effective Date, regardless of the date on which the award agreement or other document setting forth the terms and conditions of the Covered Executive’s compensation became effective, including, without limitation, compensation received under the Exelon Corporation 2020 Long-Term Incentive Plan, the 2023  Exelon Corporation Annual Incentive Program, and any successor plan to each of the foregoing. b) This Policy shall be binding and enforceable against all Covered Executives and their beneficiaries, heirs, executors, administrators, or other legal representatives. c) All issues concerning the construction, validity, enforcement and interpretation of this Policy and all related documents, including, without limitation, any employment agreement, offer letter, equity award agreement or similar agreement, shall be governed by, and construed in accordance with, the laws of the  Commonwealth of Pennsylvania, without giving effect to any choice of law or conflict of law rules or  provisions (whether of the Commonwealth of Pennsylvania or any other jurisdiction) that would cause  the application of the laws of any jurisdiction other than the Commonwealth of Pennsylvania. d) The Covered Executives, their beneficiaries, executors, administrators and any other legal representative  and the Company shall initially attempt to resolve all claims, disputes, or controversies (“Dispute”) arising under, out of or in connection with this Policy by conducting good faith negotiations amongst themselves.

Any Party may give the other Party written notice of any Dispute, and if the matter has not been resolved  within thirty (30) days from notice of the Dispute, either Party may initiate arbitration by filing a demand  with Judicial Arbitration and Mediation Services, Inc. (“JAMS”), as set forth below. To ensure the timely and economical resolution of disputes that arise in connection with this Policy, any and all disputes, claims or causes of action arising from or relating to the enforcement, performance or interpretation of this  Policy shall be resolved to the fullest extent permitted by law by final, binding and confidential arbitration, by a single arbitrator, in the location of the principal place of business of the Company Affiliate that  employs the Covered Executive, and conducted by JAMS under its applicable rules. To the fullest extent  permitted by law, the Covered Executives, their beneficiaries, executors, administrators and any other legal representative and the Company, shall waive (and shall hereby be deemed to have waived) (1) the right to resolve any such dispute through a trial by jury or judge or administrative proceeding; and (2) any objection to arbitration taking place in the location provided for above. The arbitrator shall: (i) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would

 
6  otherwise be permitted by law; and (ii) issue a written arbitration decision, to include the arbitrator’s  essential findings and conclusions and a statement of the award. The arbitrator shall be authorized to award any or all remedies that any party would be entitled to seek in a court of law. The award rendered by the arbitrator shall be final and binding on the parties and may be entered and enforced in any court  having jurisdiction. Except as may be required by law (including without limitation Securities and Exchange Act regulations), to enforce the terms of any award, or to comply with the listing rules of any exchange on which the Company’s stock is listed, neither a party nor the arbitrator(s) may disclose the existence, content, or results of any arbitration without the prior written consent of both parties. Notwithstanding  the foregoing, the Company shall be entitled to seek a restraining order or any injunctive relief in any court of competent jurisdiction to preserve its ability to recover in arbitration any Erroneously Awarded Compensation or otherwise to preserve its right to any other available relief in arbitration. Such restraining order or injunction may be granted without the necessity of the Company’s posting any bond,  except to the extent otherwise required by applicable law. e) If any provision of this Policy is determined to be unenforceable or invalid under any applicable law, such provision will be applied to the maximum extent permitted by applicable law and shall automatically be deemed amended in a manner consistent with its objectives to the extent necessary to conform to any limitations required under applicable law.
