EXELON REPORTS FIRST QUARTER 2020 RESULTS

Earnings Release Highlights

• GAAP Net Income of $0.60 per share and Adjusted (non-GAAP) Operating Earnings of $0.87 per share for the first quarter of 2020

• Revising range for full year 2020 adjusted (non-GAAP) operating earnings guidance to $2.80-$3.10 per share from original guidance of $3.00-$3.30 per share

• Strong utility reliability performance - every utility achieved top quartile in outage frequency and outage duration

• Generations’ nuclear fleet capacity factor was 93.9% for the quarter, ahead of the industry average of 91% (based on full year 2019)

CHICAGO (May 8, 2020) — Exelon Corporation (Nasdaq: EXC) today reported its financial results for the first quarter of 2020.

“We had another strong quarter, with each of our utilities achieving high reliability performance and our nuclear fleet completing seven of eight refueling outages - nearly all shorter than planned,” said Christopher M. Crane, president and CEO of Exelon. “The consistent performance of our frontline employees in providing safe and reliable service has never been more evident as we all confront the global pandemic and the devastating disruption to our economy. In recognition of these extraordinary circumstances, we are supporting customers experiencing financial hardship by suspending disconnections, waiving new late charges and reconnecting customers on request. We remain on track to invest $26 billion across our utilities to further improve reliability and customer service, and we have contributed more than $5.9 million to national and local organizations to provide immediate relief to communities affected by COVID-19.”

“Despite experiencing one of the warmest winters on record and significant erosion of demand as a result of the pandemic, we reported solid adjusted (non-GAAP) earnings of 0.87 per share, coming in just below the midpoint of our guidance range,” said Joseph Nigro, senior executive vice president and CFO of Exelon. “We identified an additional $250 million in cost savings and lowered capital expenditures at Exelon Generation by $125 million. However, even with these and other actions, the unprecedented slowdown in economic activity and unpredictable nature of the recovery has led us to lower our full-year earnings guidance from $3.00-$3.30 per share to $2.80-$3.10 per share. We will continue to look for ways to improve our earnings and cash flow this year.”

First Quarter 2020

Exelon's GAAP Net Income for the first quarter of 2020 decreased to $0.60 per share from $0.93 per share in the first quarter of 2019. Adjusted (non-GAAP) Operating Earnings remained consistent at $0.87 per share in both the first quarter of 2020 and 2019. 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 first quarter of 2020 primarily reflect:

• Lower utility earnings primarily due to unfavorable weather conditions at PECO and PHI and lower allowed electric distribution ROE due to a decrease in treasury rates at ComEd, partially offset by regulatory rate increases at BGE and PHI and distribution formula rate timing at ComEd; and

• Higher Generation earnings due to increased revenue from ZECs in New Jersey, lower operating and maintenance expense, and an income tax settlement, partially offset by lower realized energy prices, lower capacity revenues and increased nuclear outage days.

Operating Company Results¹ 

ComEd

ComEd's first quarter of 2020 GAAP Net Income and Adjusted (non-GAAP) Operating Earnings increased to $168 million from $157 million in the first quarter of 2019, primarily due to distribution formula rate timing partially offset by lower allowed electric distribution ROE due to a decrease in treasury rates. Due to revenue decoupling, ComEd's distribution earnings are not affected by actual weather or customer usage patterns.

PECO

PECO’s first quarter of 2020 GAAP Net Income decreased to $140 million from $168 million in the first quarter of 2019. PECO’s Adjusted (non-GAAP) Operating Earnings for the first quarter of 2020 decreased to $140 million from $169 million in the first quarter of 2019, primarily due to unfavorable weather conditions.

BGE

BGE’s first quarter of 2020 GAAP Net Income increased to $181 million from $160 million in the first quarter of 2019. BGE’s Adjusted (non-GAAP) Operating Earnings for the first quarter of 2020 increased to $182 million from $161 million compared with the first quarter of 2019, primarily due to regulatory rate increases.Due to revenue decoupling, BGE's distribution earnings are not affected by actual weather or customer usage patterns.

PHI

PHI’s first quarter of 2020 GAAP Net Income decreased to $108 million from $117 million in the first quarter of 2019. PHI’s Adjusted (non-GAAP) Operating Earnings for the first quarter of 2020 decreased to $110 million from $118 million in the first quarter of 2019, primarily due to unfavorable weather conditions in Delaware and New Jersey, partially offset by regulatory rate increases. 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's first quarter of 2020 GAAP Net Income decreased to $45 million from $363 million in the first quarter of 2019. Generation’s Adjusted (non-GAAP) Operating Earnings for the first quarterof2020 increased to $312 million from $294 million in the first quarter of 2019, primarily due to increased revenue from ZECs in New Jersey, lower operating and maintenance expense and an income tax settlement, partially offset by lower realized energy prices, lower capacity revenues and increased nuclear outage days.

As of March 31, 2020, the percentage of expected generation hedged is 89%-92% and 70%-73% for 2020 and 2021, respectively.

Recent Developments and First Quarter Highlights

• COVID-19: Exelon is closely monitoring developments related to the global outbreak (pandemic) of the 2019 novel coronavirus (COVID-19) pandemic and is taking proactive measures to protect the health and safety of employees, contractors and customers. As a provider of critical resources, Exelon has robust plans and contingencies in place to ensure business and operational continuity across a wide range of potentially disruptive events, including extensive preparedness for major public health crises. Exelon and its operating companies are working in close coordination with designated state and local emergency preparedness and health officials, and at the federal level through the Electric Subsector Coordinating Council. All Exelon employees have access to up-to-date information and resources and are following Centers for Disease Control guidelines to ensure safety. In addition, Exelon utilities have established incident command centers to address emergent customer and employee needs in real time.

While there was no material impact to Exelon’s financial statements for the first quarter of 2020 due to COVID-19, PECO, DPL Delaware, ACE and Generation expect a reduction in operating revenues for the nine months ending December 31, 2020 due to expected reduction in electric load. There remains significant uncertainty in the economic forecast for the remainder of the year and its impact on Exelon’s operating revenues. However, Exelon identified and is pursuing approximately $250 million in cost savings across its operating companies to offset part of the expected unfavorable impacts on operating revenues.

• ComEd Distribution Formula Rate: On April 16, 2020, ComEd filed its annual distribution formula rate update with the Illinois Commerce Commission (ICC). The ICC approval is due by December 2020 and the rates will take effect in January 2021. The filing request includes a total decrease to the revenue requirement of $11 million, reflecting an increase of $51 million for the initial revenue requirement for 2020 and a decrease of $62 million related to the annual reconciliation for 2019. The revenue requirement for 2020 and annual reconciliation for 2019 provide for a weighted average debt and equity return on distribution rate base of 6.28% inclusive of a requested ROE of 8.38%.

• DPL Delaware Gas Base Rate Case: On Feb. 21, 2020, DPL Delaware filed an application with the Delaware Public Service Commission (DPSC) to increase its annual gas distribution rates by $9 million, reflecting an ROE of 10.3%. DPL currently expects a decision in the first quarter of 2021 but cannot predict if the DPSC will approve the application as filed.

• DPL Delaware Electric Base Rate Case: On March 6, 2020, DPL Delaware filed an application with the DPSC to increase its annual electric distribution rates by $24 million, reflecting an ROE of 10.3%. DPL currently expects a decision in the first quarter of 2021 but cannot predict if the DPSC will approve the application as filed.

• Nuclear Operations: Generation’s nuclear fleet, including its owned output from the Salem Generating Station and 100% of the CENG units, produced 42,555 gigawatt-hours (GWhs) in the first quarter of 2020, compared with 45,715 GWhs in the first quarter of 2019. Excluding Salem, the Exelon-operated nuclear plants at ownership achieved a 93.9% capacity factor for the first quarter of 2020, compared with 97.1% for the first quarter of 2019. The number of planned refueling outage days in the first quarter of 2020 totaled 94, compared with 74 in the first quarter of 2019. There were 11 non-refueling outage days in the first quarter of 2020 and none in the first quarter of 2019.

• Fossil and Renewables Operations: The Dispatch Match rate for Generation’s fossil and hydro fleet was 98.2% in the first quarter of 2020, compared with 97.8% in the first quarter of 2019. Energy Capture for the wind and solar fleet was 94.7% in the first quarter of 2020, compared with 96.5% in the first quarter of 2019.

Non-GAAP Financial Measures

In addition to net income as determined under generally accepted accounting principles in the United States (GAAP), 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 measure is intended to enhance an investor’s overall understanding of period over period operating results and provide an indication of Exelon’s baseline operating performance excluding items that are considered by management to be not directly related to the ongoing operations of the business. In addition, this measure 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’ presentation. The Company has provided the non-GAAP financial measure as supplemental information and in addition to the financial measures that are calculated and presented in accordance with GAAP. Adjusted (non-GAAP) Operating Earnings should not be deemed more useful than, a substitute for, or an alternative to the most comparable GAAP Net Income measures provided in this earnings release and attachments. This press release and earnings release attachments provide reconciliations of Adjusted (non-GAAP) Operating Earnings to the most directly comparable financial measures calculated and presented in accordance with GAAP, are posted on Exelon’s website: www.exeloncorp.com, and have been furnished to the Securities and Exchange Commission on Form 8-K on May 8, 2020.

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. For all items except the unrealized gains and losses related to NDT fund investments, the marginal statutory income tax rates for 2020 and 2019 ranged from 26.0% to 29.0%. Under IRS regulations, NDT fund investment returns are taxed at different rates for investments if they are in qualified or non-qualified funds. The effective tax rates for the unrealized gains and losses related to NDT fund investments were 45.5% and 45.4% for the three months ended March 31, 2020 and 2019, respectively.

(a) Other primarily includes eliminating and consolidating adjustments, Exelon’s corporate operations, shared service entities and other financing and investment activities.

(b) For ComEd, BGE, Pepco and DPL Maryland, customer rates are adjusted to eliminate the impacts of weather and customer usage on distribution volumes.

(c) For regulatory recovery mechanisms, including ComEd’s distribution formula rate, ComEd, PECO, BGE and PHI utilities transmission formula rates, and riders across all utilities, revenues increase and decrease i) as fully recoverable costs fluctuate (with no impact on net earnings), and ii) pursuant to changes in rate base, capital structure and ROE (which impact net earnings).

(1) Reflects the impact of net unrealized gains and losses on Generation’s NDT fund investments for Non-Regulatory and Regulatory Agreement Units. The impacts of the Regulatory Agreement Units, including the associated income taxes, are contractually eliminated, resulting in no earnings impact.

(2) In 2019, primarily reflects accelerated depreciation and amortization expenses associated with the early retirement of the TMI nuclear facility and a benefit associated with a remeasurement of the TMI ARO. In 2020, primarily reflects accelerated depreciation and amortization expenses associated with the early retirement of certain fossil sites.

(3) Primarily represents reorganization costs related to cost management programs.

(4) Represents elimination from Generation’s results of the noncontrolling interests related to certain exclusion items, primarily related to unrealized gains and losses on NDT fund investments for CENG units.

(5) For ComEd, reflects increased electric distribution and energy efficiency revenues (due to higher rate base, higher fully recoverable costs and distribution formula rate timing, partially offset by lower electric distribution ROE due to decreased treasury rates). For BGE, and PHI, reflects increased revenue as a result of rate increases.

(6) Primarily reflects the permanent cease of generation operations at TMI in September 2019 and an increase in nuclear outage days.

(7) Primarily reflects a decrease in fuel prices and decreased nuclear output as a result of the permanent cease of generation operations at TMI.

(8) Reflects decreased capacity revenues in the Mid-Atlantic, Midwest, New York, and Other Power Regions.

(9) Primarily reflects the approval of the New Jersey ZEC Program in the second quarter of 2019.

(10) Primarily reflects lower realized energy prices.

(11) For Generation, primarily reflects decreased costs related to the permanent cease of generation operations at TMI and lower labor costs resulting from previous cost management programs.

(12) Primarily reflects an increase in the number of nuclear outage days in 2020.

(13) Reflects ongoing capital expenditures across all utilities. For ComEd, also reflects increased amortization of deferred energy efficiency costs pursuant to FEJA. For Generation, reflects a decrease primarily due to the extension of the Peach Bottom license.

(14) For Generation, includes an interest benefit related to a one-time income tax settlement.

(15) For Generation, primarily reflects a one-time income tax settlement partially offset by a reduction in renewable tax credits.

(16) Reflects elimination from Generation’s results of activity attributable to noncontrolling interests, primarily for CENG.

(17) For Generation, primarily reflects higher realized NDT fund gains.
