Item 1.01. Entry into a Material Definitive Agreement.

On May 19, 2025, Commonwealth Edison Company (ComEd) issued $725 million aggregate principal amount of its First Mortgage 5.950% Bonds, Series 138, due June 1, 2055 (the Bonds). See Item 2.03 below for a description of the Bonds and related agreements.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On May 19, 2025, ComEd issued $725 million aggregate principal amount of its First Mortgage 5.950% Bonds, Series 138, due June 1, 2055. The Bonds were issued pursuant to ComEd’s Mortgage dated July 1, 1923, as amended and supplemented by supplemental indentures, including the Supplemental Indenture dated August 1, 1944 (Mortgage) and the Supplemental Indenture dated as of May 1, 2025 (Supplemental Indenture). The Mortgage is a first mortgage on ComEd’s utility plant. The proceeds of the Bonds will be used by ComEd to repay ComEd’s outstanding commercial paper obligations, and to fund other general corporate purposes. The Bonds were registered under the Securities Act of 1933, as amended, pursuant to ComEd’s Registration Statement on Form S-3 (Registration No. 333-284911-01), as amended, filed with the Securities and Exchange Commission (SEC), which registration statement was declared effective by the SEC on April 8, 2025.

The Bonds carry an interest rate of 5.950% per annum. Interest on the Bonds is payable semi-annually on June 1 and December 1, commencing December 1, 2025. The Bonds are redeemable in whole or in part at ComEd’s option at any time prior to December 1, 2054 (six months prior to the maturity date of the Bonds) (Par Call Date), at a redemption price equal to the greater of 100% of the principal amount to be redeemed or a “make-whole” redemption price calculated as provided in the Supplemental Indenture, plus accrued and unpaid interest to the redemption date. On or after the Par Call Date, we may redeem the Bonds, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Bonds being redeemed plus accrued and unpaid interest thereon to the redemption date. A copy of the Supplemental Indenture, which sets forth the terms of the Bonds, is attached hereto as Exhibit 4.1 and is incorporated herein by reference.

In connection with the issuance of the Bonds, Ballard Spahr LLP provided ComEd with the legal opinion attached to this Current Report as Exhibit 5.1.

BNP Paribas Securities Corp., MUFG Securities Americas Inc., and SMBC Nikko Securities America, Inc., as representatives of the several underwriters named therein, is filed as Exhibit 1.1 to this Current Report.

* * * * *

This Current Report contains certain forward-looking statements within the meaning of federal securities laws that are subject to risks and uncertainties. Words such as “could,” “may,” “expects,” “anticipates,” “will,” “targets,” “goals,”

“projects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “predicts,” “should,” and variations on such words, and similar expressions that reflect our current views with respect to future events and operational, economic, and financial performance, are intended to identify such forward-looking statements.

Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the following important factors that may cause our actual results or outcomes to differ materially from those contained in our forward-looking statements, including, but not limited to: unfavorable legislative and/or regulatory actions; uncertainty as to outcomes and timing of regulatory approval proceedings and/or negotiated settlements thereof; environmental liabilities and remediation costs; state and federal legislation requiring use of low-emission, renewable, and/or alternate fuel sources and/or mandating implementation of energy conservation programs requiring implementation of new technologies; challenges to tax positions taken, tax law changes, and difficulty in quantifying potential tax effects of business decisions; negative outcomes in legal proceedings; adverse impact of the activities associated with the past deferred prosecution agreement (DPA) and now-resolved SEC investigation on ComEd's reputation and relationships with legislators, regulators, and customers; physical security and cybersecurity risks; 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; disruptions or cost increases in the supply chain, including shortages in labor, materials or parts, or significant increases in relevant tariffs; lack of sufficient capacity to meet actual or forecasted demand or disruptions at power generation facilities owned by third parties; emerging technologies that could affect or transform the energy industry; instability in capital and credit markets; a downgrade of ComEd's credit ratings or other failure to satisfy the credit standards in ComEd's agreements or regulatory financial requirements; significant economic downturns or increases in customer rates; impacts of climate change and weather on energy usage and maintenance and capital costs; and impairment of long-lived assets, goodwill, and other assets.

New factors emerge from time to time, and it is impossible for us to predict all of such factors, nor can we assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. For more information, see those factors discussed in ComEd's most recent Annual Report on Form 10-K, including in Part I, ITEM 1A, any subsequent Quarterly Reports on Form 10-Q, and in other reports filed by ComEd from time to time with the SEC.

Investors are cautioned not to place undue reliance on these forward-looking statements, whether written or oral, which apply only as of the date of this Current Report. ComEd undertakes no obligation to publicly release any revision to its forward-looking statements to reflect events or circumstances after the date of this Current Report.
