Item 5.04. Temporary Suspension of Trading Under Registrant’s Employee Benefit Plans.

Exelon Corporation (the “Company” or “Exelon”) will be effecting a vendor change for its Employee Savings Plan (the “ESP”) effective on or about December 22, 2025. As a result of this transition, there will be a blackout period during which participants and beneficiaries in the ESP will be temporarily unable to change their contribution rate, direct or diversify investments in their individual accounts (including transfers into or out of Exelon Corporation common stock), or obtain a loan, withdrawal or distribution from their ESP account. The blackout period is expected to begin at 4:00 p.m. Eastern Time on December 3, 2025, and end during the week of December 22, 2025 (the “Plan Blackout Period”).

On November 18, 2025, the Company sent a notice (the “Blackout Notice”) to its directors and executive officers pursuant to Section 306(a) of the Sarbanes-Oxley Act of 2002 and Section 104 of Regulation BTR under the Securities Exchange Act of 1934, as amended. The Blackout Notice informed directors and executive officers that during the Plan Blackout Period, they will be prohibited from directly or indirectly purchasing, selling, or otherwise acquiring, disposing or transferring shares of Exelon common stock or derivative securities, acquired in connection with their service as a director or employment as an executive officer of the Company.

A copy of the Blackout Notice is attached as Exhibit 99.1 and is incorporated by reference in this Current Report on Form 8-K. During the Plan Blackout Period and for a period of two years after the ending date of the Plan Blackout Period, security holders or other interested persons may obtain, without charge, information about the actual beginning and ending dates of the Plan Blackout Period and other information regarding the Plan Blackout Period from Exelon’s Corporate Secretary by sending a written request to Exelon Corporation, Attn: Corporate Secretary, 10 South Dearborn Street, P.O.
