CHICAGO (Aug. 4, 2021) - Exelon Corporation (Nasdaq: EXC) today reported its financial results for the second quarter of 2021.

"Ongoing investments in technology and infrastructure continue to drive high reliability and customer satisfaction across our six utilities, and today we announced a new 'path to clean' goal that will put Exelon utilities on course to achieve net-zero emissions from operations by 2050," said Christopher Crane, president and CEO of Exelon. "We also are encouraged to see growing support at the federal level for policies that would value the clean energy from our nuclear fleet, but passage of legislation remains uncertain and, regardless, will come too late to save our Byron and Dresden plants from early retirement this fall. While we remain hopeful that a state solution will pass in time to save the plants, clean energy legislation in Illinois remains caught in negotiations over unrelated policy matters, leaving us no choice but to continue down the path of closing the plants. Looking ahead, we continue to execute our plan to separate our utility and generation businesses into two financially strong, independent companies, and we remain on track to close in the first quarter of 2022."

"Adjusted (non-GAAP) Operating Earnings of $0.89 per share in the second quarter was $0.34 ahead of the same period last year, driven in part by the absence of storm costs at Exelon utilities and the recovery of costs associated with ongoing investments to improve reliability and service for customers," said Joseph Nigro, senior executive vice president and CFO of Exelon. "Exelon Generation also had a strong quarter, with year-over-year earnings up $0.14 per share due to unrealized and realized gains on Constellation's Technology Venture investments, fewer planned nuclear outage days and realized gains in our nuclear decommissioning trust funds. As a result of these and other factors, we are reaffirming our full-year Adjusted (non-GAAP) Operating Earnings guidance range of $2.60-$3.00 per share."

Second Quarter 2021

Exelon's GAAP Net Income for the second quarter of 2021 decreased to $0.41 per share from $0.53 GAAP Net Income per share in the second quarter of 2020. Adjusted (non-GAAP) Operating Earnings for the second quarter of 2021 increased to $0.89 per share from $0.55 per share in the second quarter of 2020. For the reconciliations of GAAP Net Income to Adjusted (non-GAAP) Operating Earnings, refer to the tables beginning on page 5.

Adjusted (non-GAAP) Operating Earnings in the second quarter of 2021 primarily reflect:

• Higher utility earnings primarily due to higher electric distribution earnings at ComEd from higher rate base and higher allowed ROE due to an increase in treasury rates; the favorable impacts of the multi-year plan at BGE; regulatory rate increases at PHI; favorable volume at PECO and PHI; and lower storm costs at PECO due to the absence of the June 2020 storms.
• Higher Generation earnings primarily due to higher net unrealized and realized gains on equity investments; higher realized gains on nuclear decommissioning trust (NDT) funds; and decreased nuclear outage days.

Operating Company Results1

ComEd

ComEd's second quarter of 2021 GAAP Net Income increased to $192 million from a GAAP Net Loss of $(61) million in the second quarter of 2020. ComEd's Adjusted (non-GAAP) Operating Earnings for the second quarter of 2021 increased to $195 million from $150 million in the second quarter of 2020, primarily due to higher electric distribution earnings from higher rate base and higher allowed ROE due to an increase in treasury rates. Due to revenue decoupling, ComEd's distribution earnings are not affected by actual weather or customer usage patterns.

PECO

PECO's second quarter of 2021 GAAP Net Income increased to $104 million from $39 million in the second quarter of 2020. PECO's Adjusted (non-GAAP) Operating Earnings for the second quarter of 2021 increased to $107 million from $44 million in the second quarter of 2020, primarily due to lower storm costs due to the absence of the June 2020 storms and favorable volume.

___________

1Exelon's five business units include ComEd, which consists of electricity transmission and distribution operations in northern Illinois; PECO, which consists of electricity transmission and distribution operations and retail natural gas distribution operations in southeastern Pennsylvania; BGE, which consists of electricity transmission and distribution operations and retail natural gas distribution operations in central Maryland; PHI, which consists of electricity transmission and distribution operations in the District of Columbia and portions of Maryland, Delaware, and New Jersey and retail natural gas distribution operations in northern Delaware; and Generation, which consists of owned and contracted electric generating facilities and wholesale and retail customer supply of electric and natural gas products and services, including renewable energy products and risk management services.

BGE's second quarter of 2021 GAAP Net Income increased to $45 million from $39 million in the second quarter of 2020. BGE's Adjusted (non-GAAP) Operating Earnings for the second quarter of 2021 increased to $48 million from $43 million in the second quarter of 2020, primarily due to the favorable impacts of the multi-year plan. Due to revenue decoupling, BGE's distribution earnings are not affected by actual weather or customer usage patterns.

PHI

PHI's second quarter of 2021 GAAP Net Income increased to $141 million from $94 million in the second quarter of 2020. PHI's Adjusted (non-GAAP) Operating Earnings for the second quarter of 2021 increased to $144 million from $98 million in the second quarter of 2020, primarily due to distribution and transmission rate increases at DPL and ACE, favorable volume at ACE, and lower credit loss expense in 2021 due to an increase in 2020 as a result of COVID-19. Due to revenue decoupling, PHI's distribution earnings related to Pepco Maryland, DPL Maryland and Pepco District of Columbia are not affected by actual weather or customer usage patterns.

Generation

Generation had a GAAP Net Loss of $(61) million in the second quarter of 2021 compared with GAAP Net Income of $476 million in the second quarter of 2020. Generation's Adjusted (non-GAAP) Operating Earnings for the second quarter of 2021 increased to $393 million from $252 million in the second quarter of 2020, primarily due to net unrealized and realized gains on equity investments, higher realized gains on NDT funds, and decreased nuclear outage days.

As of June 30, 2021, the percentage of expected generation hedged is 98%-101% for 2021.

Recent Developments and Second Quarter Highlights

• Exelon Utilities "Path to Clean": Today, the Exelon utilities announced a "path to clean" goal to collectively reduce their operations-driven emissions 50% by 2030 against a 2015 baseline and to reach net zero operations-driven emissions by 2050. This goal builds upon Exelon's long-standing commitment to reducing our greenhouse gas emissions. The Exelon utilities "path to clean" will include efficiency and clean electricity for operations, vehicle fleet electrification, equipment and processes to reduce sulfur hexafluoride (SF6) leakage, modern natural gas infrastructure to minimize methane leaks and increase safety and reliability, and investment and collaboration to develop new technologies.
• PECO Pennsylvania Natural Gas Distribution Base Rate Case: On June 22, 2021, the Pennsylvania Public Utility Commission (PAPUC) issued an order approving a $29 million increase in PECO's annual natural gas distribution revenues, reflecting a ROE of 10.24%. The rates were effective on July 1, 2021.
• Pepco District of Columbia Electric Distribution Base Rate Case: On June 8, 2021, the Public Service Commission of the District of Columbia (DCPSC) approved Pepco's multi-yearplan for the 18-monthsremaining in 2021 through 2022. The order approved an incremental increase in Pepco's electric distribution rates of $42 million and $67 million, before offsets, for the remainder of 2021 and 2022, respectively, reflecting an ROE of 9.275%. However, the DCPSC utilized the acceleration of refunds for certain tax benefits along with other rate relief to partially offset the customer rate increases by $22 million and $40 million for the remainder of 2021 and 2022, respectively. These rates were effective on July 1, 2021.

• Pepco Maryland Electric Distribution Base Rate Case: On June 28, 2021, the Maryland Public Service Commission (MDPSC) approved Pepco's three-year multi-yearplan for April 1, 2021 through March 31, 2024. The order approved an incremental increase in Pepco's electric distribution rates of $21 million, $16 million, and $15 million, before offsets, for the 12-monthperiods ending March 31, 2022, 2023, and 2024, respectively, reflecting an ROE of 9.55%. However, the MDPSC utilized the acceleration of refunds for certain tax benefits to fully offset the increases such that customer rates remain unchanged through March 31, 2022. The MDPSC has deferred a decision on whether to use additional tax benefits to offset the customer rate increases for periods after March 31, 2022. These rates were effective on June 28, 2021.
• ACE New Jersey Electric Distribution Base Rate Case: On July 14, 2021, the New Jersey Board of Public Utilities (NJBPU) approved an increase in ACE's annual electric distribution base rates of $41 million (before New Jersey sales and use tax), reflecting an ROE of 9.6%. The order allows ACE to retain approximately $11 million of certain tax benefits which will result in a decrease to income tax expense in the third quarter of 2021. These rates are effective on Jan. 1, 2022.
• Nuclear Operations: Generation's nuclear fleet, including its owned output from the Salem Generating Station and 100% of the CENG units, produced 43,575 gigawatt-hours (GWhs) in the second quarter of 2021, compared with 43,416 GWhs in the second quarter of 2020. Excluding Salem, the Exelon-operated nuclear plants at ownership achieved a 93.7% capacity factor for the second quarter of 2021, compared with 95.4% for the second quarter of 2020. The number of planned refueling outage days in the second quarter of 2021 totaled 66, compared with 92 in the second quarter of 2020. There were seven non-refueling outage days in the second quarter of 2021 and none in the second quarter of 2020.
• Fossil and Renewables Operations: The Dispatch Match rate for Generation's gas and hydro fleet was 99.5% in the second quarter of 2021, compared with 97.4% in the second quarter of 2020.
  Energy Capture for the wind and solar fleet was 96.0% in the second quarter of 2021, compared with 92.7% in the second quarter of 2020.
• Financing Activities:
• • On June 10, 2021, BGE issued $600 million of its 2.25% notes due June 15, 2031. BGE used the proceeds to repay a portion of outstanding commercial paper obligations, repay existing indebtedness, and to fund other general corporate purposes.
  • On May 13, 2021, West Medway II, LLC (West Medway II), an indirect subsidiary of Generation, entered into a financing agreement for a $150 million nonrecourse senior secured term loan credit facility scheduled to mature on March 31, 2026. The term loan bears interest at an average blended interest rate of LIBOR plus 3%. Generation used the proceeds for general corporate purposes. In addition to the financing, West Medway II entered into interest rate swaps with an initial notional amount of $113 million at an interest rate of 0.61% to manage a portion of the interest rate exposure in connection with financing.
