Non-GAAP Financial Measures Exelon reports its financial results in accordance with accounting principles generally accepted in the United States (GAAP). Exelon supplements the reporting of financial information determined in accordance with GAAP with certain non-GAAP financial measures, including adjusted (non-GAAP) operating earnings, adjusted (non-GAAP) operating and maintenance expense, total gross margin, earnings before interest, taxes, depreciation and amortization (EBITDA), and adjusted cash flow from operations (non-GAAP) or free cash flow. Adjusted (non-GAAP) operating earnings exclude certain costs, expenses, gains and losses and other specified items, including mark-to-market adjustments from economic hedging activities, unrealized gains and losses from nuclear decommissioning trust fund investments merger and integration costs, certain costs incurred associated with the PHI acquisition, merger commitments related to the settlement of the PHI acquisition, the impairment of certain long-lived assets, plant retirements and divestitures, costs related to the cost management program, and the non-controlling interest in CENG. Adjusted (non-GAAP) operating and maintenance expense excludes regulatory operating and maintenance costs for the utility businesses and direct cost of sales for certain Constellation businesses, decommissioning costs that do not affect profit and loss, and the impact from operating and maintenance expense related to variable interest entities at Generation. Total gross margin (non-GAAP) is defined as operating revenues less purchased power and fuel expense, excluding revenue related to decommissioning, gross receipts tax, Exelon Nuclear Partners, the operating services agreement with Fort Calhoun, variable interest entities and net of direct cost of sales for certain Constellation businesses. EBITDA is defined as earnings before interest, taxes, depreciation and amortization, including nuclear fuel amortization expense. Adjusted cash flow from operations (non-GAAP) or free cash flow primarily includes net cash flows from operating activities and net cash flows from investing activities excluding capital expenditures at ownership and nuclear fuel expense. Due to the forward-looking nature of any forecasted non-GAAP measures, information to reconcile the forecast adjusted (non-GAAP) measures to the most directly comparable GAAP measure is not currently available, as management is unable to project all of these items for future periods.

Non-GAAP Financial Measures Continued This information is intended to enhance an investor’s overall understanding of period over period financial results and provide an indication of Exelon’s baseline operating performance by excluding items that are considered by management to be not 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. These non-GAAP financial measures are not a presentation defined under GAAP and may not be comparable to other companies’ presentation. Exelon has provided these non-GAAP financial measure as supplemental information and in addition to the financial measures that are calculated and presented in accordance with GAAP. These non-GAAP measures should not be deemed more useful than, a substitute for, or an alternative to the most comparable GAAP measures provided in the materials presented. Reconciliations of these non-GAAP measures to the most comparable GAAP measures are provided in the footnotes, appendices and attachments to this presentation.

The PSC also disallowed $30M of added costs associated with BGE’s usage of the Baltimore City conduit system. 6/30/16 filed request for rate case re-hearing asking that the PSC reconsider decisions resulting in $84M write-off and the disallowance of $30M of added Baltimore City conduit system; Request would result in no additional increase to customer rates. The PSC requested and received comments on the rehearing request from the other parties. 7/29/2016 PSC issued order on rehearing granting further increase to electric revenue requirement of $2.4M and gas revenue requirement of $0.1M and to defer post test year smart grid costs in a new regulatory asset so it may seek recovery of the costs in a future base rate proceeding. The rehearing decision will result in a reversal of the write-off of $32.4M. The PSC did not revise its decision on the Baltimore City conduit fee increase.

ComEd April 2016 Distribution Formula Rate Docket # 16-0259 Filing Year 2015 Calendar Year Actual Costs and 2016 Projected Net Plant Additions are used to set the rates for calendar year 2017. Rates currently in effect (docket 15-0287) for calendar year 2016 were based on 2014 actual costs and 2015 projected net plant additions. Reconciliation Year Reconciles Revenue Requirement reflected in rates during 2015 to 2015 Actual Costs Incurred. Revenue requirement for 2015 is based on docket 14-0312 (2013 actual costs and 2014 projected net plant additions) approved in December 2014. Common Equity Ratio ~46% for both the filing and reconciliation year ROE 8.64% for the filing year (2015 30-yr Treasury Yield of 2.84% + 580 basis point risk premium) and 8.59% for the reconciliation year (2015 30-yr Treasury Yield of 2.79% + 580 basis point risk premium – 5 basis points performance metrics penalty). For 2016 and 2017, the actual allowed ROE reflected in net income will ultimately be based on the average of the 30-year Treasury Yield during the respective years plus 580 basis point spread, absent any metric penalties Requested Rate of Return ~7% for both the filing and reconciliation years Rate Base $8,830 million– Filing year (represents projected year-end rate base using 2015 actual plus 2016 projected capital additions). 2016 and 2017 earnings will reflect 2016 and 2017 year-end rate base respectively. $7,780 million - Reconciliation year (represents year-end rate base for 2015) Revenue Requirement Increase $138M increase ($1M decrease due to the 2015 reconciliation and collar adjustment offset by a $139M increase related to the filing year). The 2015 reconciliation impact on net income was recorded in 2015 as a regulatory asset. Timeline 04/13/16 Filing Date 240 Day Proceeding The 2016 distribution formula rate filing established the net revenue requirement used to set the rates that will take effect in January 2017 after the Illinois Commerce Commission's (ICC’s) review. There are two components to the annual distribution formula rate filing: Filing Year: Based on 2015 costs and 2016 projected plant additions. Annual Reconciliation: For 2015, this amount reconciles the revenue requirement reflected in rates in effect during 2015 to the actual costs for that year. The annual reconciliation impacts cash flow in 2017 but the earnings impact has been recorded in 2015 as a regulatory asset. Given the retroactive ratemaking provision in the Energy Infrastructure Modernization Act (EIMA) legislation, ComEd net income during the year will be based on actual costs with a regulatory asset/liability recorded to reflect any under/over recovery reflected in rates. Revenue Requirement in rate filings impacts cash flow.

Exelon’s Policy Priorities Bill Von Hoene Senior Executive Vice President & Chief Strategy Officer Kathleen Barrón Senior Vice President Federal Regulatory Affairs and Wholesale Market Policy

Exelon Policy Priorities Create support for current challenged plants through federal and state initiatives Support the ultimate pricing of carbon in the market on a national level Modernize Utility Ratemaking to Ensure Appropriate Recovery Secure Proper Policies to Enable Innovative Technologies Recognize the Value of Zero-Carbon Electricity Regulatory and policy structure that supports clean, affordable and reliable options for all customers Invest in infrastructure that provides customer benefit through grid resiliency and efficiency Ensure fair rate structures to support new technologies Providing new technologies to respond to customer needs Open adjacent customer facing markets to sales and services

Our Carbon Policy Principles Exelon believes in our nation’s ability to transition the generation fleet to a zero-carbon future while maintaining affordable and reliable electric service for consumers For the foreseeable future, the most cost-effective carbon solution for our customers will be the continued operation of our nation’s nuclear fleet Exelon believes competitive markets produce superior results for consumers and drive innovation. However, those markets do not currently incorporate appropriate pricing for environmental attributes. Exelon is pursuing a two-part strategy for moving toward a more competitive treatment of CO2 emissions: First, we must maintain nuclear units that provide a cost effective form of CO2 abatement. The New York ZEC program demonstrates that as long as the clean energy payment required to maintain operations at existing nuclear units is lower than the social cost of CO2 emissions and the cost of CO2 abatement being paid to other zero carbon resources, maintaining nuclear capacity should be selected as the most competitive source of CO2 abatement. Second, we must continue to work toward a technology neutral price of CO2 abatement. Exelon is pursuing approaches to reflect a uniform price on CO2 in wholesale markets as an eventual substitute for technology-specific subsidies. As these approaches are phased in, the ZEC programs have been designed to automatically reduce ZEC payments in response to higher energy prices.

Existing Nuclear is the Most Cost Effective Zero Carbon Choice Carbon Price Needed (1) $16 <$20 $54 $58 $121 $286 (1) $/MWh above-market converted to carbon price needed using PJM marginal emission rate of 1,590 lbs/MWh Estimated Carbon Price Needed to Preserve Existing Nuclear, Coal to Gas Redispatch and Renewable Entry at Near-Term Technology Costs $/MWh Above Market

New York Zero Emission Credit Program Mechanics Pricing for each tranche to be administratively determined based on the USIWG Social Cost of Carbon (escalating over the term), less a fixed baseline for carbon pricing already captured through the RGGI program ($10.41/short ton) Tranche 1 yields $17.48/MWh Tranches 2-6 shall incorporate a customer protection feature to determine the ZEC. In general, the formula is: The quantity of ZECs to be purchased on an annual basis will be capped at a MWh amount that represents the verifiable historic contribution the facility has made to the clean energy resource mix Each Load Serving Entity shall be required to purchase an amount of ZECs equivalent to its load ratio share of the total electric energy load in the New York Control Area Cost recovery from ratepayers shall be incorporated into the commodity charges on customer bills ZECs will not be tradable except between NYSERDA and the LSE in the balancing process (1) The $39/MWh reference price will be updated at the time the Tranche 4 ZEC price is determined. This one-time update will be calculated by determining the historical basis over the 2017-2022 time period and adjusting the $39/MWh reference price used in the ZEC price formula if the historic basis is outside of a range of $5-7/MWh Social Cost of Carbon Baseline RGGI Effect Upstate ZEC price Zone A Forecast + Rest of Zone Forecast Capacity Price combined exceeds $39/ MWh (1)

Zero Emission Credits (ZECs) are Like Renewable Energy Credits (RECs) Both credits are for environmental attributes to meet a state environmental goal While legal challenges are likely, we believe that ZECs, like RECs, will withstand legal challenge: No affiliate contracts (Ohio) No attempt to alter FERC wholesale rate (NJ/MD) FERC has never applied the Minimum Offer Price Rule (MOPR) to existing resources; it has always been a tool to address state support for new entry Payment for ZECs is not “tethered” to action in a FERC jurisdictional market

Exelon’s Policies Priorities Appendix

Overview of New York Zero Emission Credit Program On August 1, the New York Public Service Commission (NY PSC) approved the New York Clean Energy Standard which creates a Zero Emission Credit (ZEC) program The objective of the program is to preserve the environmental attributes of zero-emissions nuclear-powered generating facilities The program creates a 12 year contract extending from April 1, 2017 through March 31, 2029 The NY PSC will determine whether a plant is eligible based on the following factors: The verifiable historic contribution of the facility to the clean energy resource mix in New York State; The degree to which energy, capacity, and ancillary services revenues projected to be received by the facility are at a level expected to preserve its environmental attributes; The costs/benefits of such attributes in relation to other clean energy alternatives; Impact of related costs on ratepayers; and, The public interest The NYPSC found in its August 1 order that the Ginna, Nine Mile Point and Fitzpatrick nuclear plants meet this public interest standard and qualify for the program The New York State Energy Research & Development Authority (NYSERDA) will centrally procure the ZECs ZECs will be procured in 6, two-year tranches

Additional License Extension for Peach Bottom Station On June 7, 2016, Exelon announced it is seeking an additional 20-year operating license for Peach Bottom from the Nuclear Regulatory Commission (NRC) The current operating licenses will expire in 2033 and 2034 If the license extensions are approved, the plants would be allowed to operate until 2053 and 2054 Exelon will file formal application for license extension in 2018. The NRC review is anticipated to take approximately 2 to 2.5 years to complete Peach Bottom is one of Exelon’s highest performing plants and one of the best in the United States 93% capacity factor in 2015 Long history of reliability No automatic trips in more than 10 years 5 consecutive breaker to breaker runs Provides 10% of Pennsylvania’s power Completed major extended power uprate in 2015, under budget and ahead of schedule, that increased site output by more than 12%

Process for Decommissioning a Nuclear Plant Sites must be decommissioned within 60 years of plant ceasing operations Exelon must submit a cost estimate for decommissioning the plants to the NRC within 2 years of permanent cessation of operations Within 2 years of permanent cessation of operations, Exelon must submit a post-shutdown decommissioning activities report (PSDAR) to the NRC and Illinois, which must include the site’s planned option for decommissioning the unit NRC will make the PSDAR available for public comment and schedule a public meeting Exelon can begin decommissioning activities after 90 days of submitting the PSDAR and after submittal of certification of permanent cessation of operations and permanent removal of fuel Exelon cannot access all the decommissioning funds until after submittal of the site-specific cost to the NRC Exelon can use one or both of two options to decommission the plants: SAFSTOR (Safe Storage): facility is placed and maintained in a condition that allows it to be safely stored and subsequently decontaminated to levels that permits the property to be released. We can choose to end SAFSTOR at any point during the 60-year period and transition to DECON. Generally, sites must spend no more than 50 years in SAFSTOR and allow 10 years for the DECON stage of decommissioning. DECON (Decontamination): Radioactive equipment and structures are removed or decontaminated to a level that permits the property to be released for use shortly after cessation of operations Terminating the NRC license: As the DECON phase nears completion, the company must submit a license termination plan to the NRC at least two years before the proposed license termination date. The license termination plan is subject to public comment. After considering the public comments, the NRC will terminate the license if all work has followed the approved license termination plan and the final radiation survey shows the site is suitable for release. Source: Nuclear Energy Institute Exelon’s schedules for decommissioning Clinton and Quad Cities nuclear stations are currently under development

Clinton and Quad Cities Nuclear Decommissioning Trust Funds It is currently estimated that Clinton will no longer meet the NRC minimum funding requirements due to the earlier commencement of decommissioning activities and a shorter time period over which the nuclear decommissioning trust fund (NDTF) investments could appreciate in value. Quad Cities would also be at risk for such a shortfall. A shortfall could require Exelon to post parental guarantees for Generation’s obligations. However, the amount of any required guarantees will ultimately be dependent on the decommissioning approach adopted at each site, the associated level of costs, and the decommissioning trust fund investment performance going forward. Considering the three alternative decommissioning approaches available to Generation for each site, the most costly estimates currently anticipated could require parental guarantees of up to $385 million for Clinton in order to access its NDTF for radiological decommissioning costs. Although Quad Cities is better positioned than Clinton to avoid the need for a parental guarantee, a guarantee of up to $135 million, at Generation’s ownership percentage, may be required in order for the site to access its NDTF for radiological decommissioning costs. Upon issuance of any required financial guarantees, Clinton and Quad Cities would be able to utilize the respective NDTFs for radiological decommissioning costs, which represent the majority of the total expected decommissioning costs. However, the NRC must approve an additional exemption in order for Generation to utilize the NDTF to pay for non-radiological decommissioning costs (i.e. spent fuel management and site restoration costs). If a unit does not receive this exemption, the costs would be borne by the owner(s). Accordingly, based on current projections, it is expected that some portion of the spent fuel management and/or site restoration costs would need to be funded through supplemental cash from Generation and others holding ownership interests. While the ultimate amounts may vary greatly and could be reduced by alternate decommissioning scenarios and/or reimbursement of certain costs under the United States Department of Energy reimbursement agreements or future litigation, across the three alternative decommissioning approaches available to Generation, for the next 10 years, Clinton could incur spent fuel management and site restoration costs of up to $160 million, net of taxes. Quad Cities is better positioned to pass the test than Clinton. Although considered unlikely, if Quad Cities fails the exemption test, at its ownership percentage Generation, could be required to pay for spent fuel management costs over the next ten years of up to $185 million, net of taxes. Potential Parental Guarantees Potential Spent Fuel and Restoration Costs Clinton Up to $385M Up to $160M Quad Cities Up to $135M Up to $185M

Does not include the impact of the CES program in NY.

ExGen Disclosures Expected generation is the volume of energy that best represents our commodity position in energy markets from owned or contracted for capacity based upon a simulated dispatch model that makes assumptions regarding future market conditions, which are calibrated to market quotes for power, fuel, load following products, and options. Expected generation assumes 12 refueling outages in 2016, 14 in 2017, and 12 in 2018 at Exelon-operated nuclear plants and Salem. Expected generation assumes capacity factors of 94.4%, 93.7% and 93.4% in 2016, 2017 and 2018 respectively at Exelon-operated nuclear plants, at ownership. These estimates of expected generation in 2017 and 2018 do not represent guidance or a forecast of future results as Exelon has not completed its planning or optimization processes for those years Excludes EDF’s equity ownership share of CENG Joint Venture Percent of expected generation hedged is the amount of equivalent sales divided by expected generation. Includes all hedging products, such as wholesale and retail sales of power, options and swaps Effective realized energy price is representative of an all-in hedged price, on a per MWh basis, at which expected generation has been hedged. It is developed by considering the energy revenues and costs associated with our hedges and by considering the fossil fuel that has been purchased to lock in margin. It excludes uranium costs and RPM capacity revenue, but includes the mark-to-market value of capacity contracted at prices other than RPM clearing prices including our load obligations.
