Southern California Edison Commences Cash Tender Offer to Purchase Any & All 5.45% Fixed-to-Floating Rate Trust Preference Securities Issued by SCE Trust V

Southern California Edison (the "Company") today announced the commencement of its cash tender offer to purchase any and all of the outstanding 5.45% Fixed-to-Floating Rate Trust Preference Securities (the "Trust Securities" and such offer, the "Offer") issued by SCE Trust V, a Delaware statutory trust subsidiary of the Company (the "Trust"), plus Accrued Distributions (as defined below).

The Offer will expire on December 19, 2025 at 5 p.m., New York City time, unless the Company extends or earlier terminates the Offer (such time and date, as the same may be extended or earlier terminated, the "Expiration Date").

The consideration for the Trust Securities tendered and accepted for purchase will equal $25 per $25 liquidation amount of Trust Securities pursuant to the Offer (the "Offer Price"), plus Accrued Distributions. As used in connection with the Offer, "Accrued Distributions" means, for each $25 liquidation amount of Trust Securities, accrued and unpaid distributions from the last distribution payment date with respect to such Trust Security up to, but not including, the Settlement Date (as defined below) of the Offer, assuming for purposes of the Offer that a distribution for such Trust Security had in fact accrued during such period. The date on which the Company will pay the aggregate purchase price for all validly tendered and not validly withdrawn Trust Securities that are accepted for purchase is referred to as the "Settlement Date." The Company expects the Settlement Date will occur promptly following the Expiration Date and acceptance of the Trust Securities for purchase.

The Company intends to pay the consideration payable by it pursuant to the Offer and the fees and expenses incurred by it in connection therewith with cash on hand.

Trust Securities tendered pursuant to the Offer may be validly withdrawn at any time on or prior to the Expiration Date by following the procedures described in the Offer to Purchase.

The terms and conditions of the Offer are described in the Offer to Purchase, dated November 20, 2025 (as it may be amended or supplemented from time to time, the "Offer to Purchase"), and the accompanying Letter of Transmittal, dated November 20, 2025 (as it may be amended or supplemented from time to time, the "Letter of Transmittal" and, together with the Offer to Purchase, the "Offer Materials"). The Offer is subject to the satisfaction or waiver of certain conditions specified in the Offer Materials.

Upon request, the Offer Materials will be provided to record holders of Trust Securities and will be furnished to brokers, dealers, commercial banks, trust companies or other nominee stockholders and similar persons whose names, or the names of whose nominees, appear on the Trust's stockholder list or, if applicable, who are listed as participants in a clearing agency's security position listing for subsequent transmittal to beneficial owners of the Trust Securities. The Offer Materials contain important information that holders are urged to read before any decision is made with respect to the Offer.
