 responsible for payment of fixed recovery charges, it may be difficult for SCE to collect fixed recovery charges from these
disconnected (former) customers, and these customers may dispute their obligation to pay the fixed recovery charge, thus potentially adversely impacting the timing and receipt of fixed recovery charge collections.

SERVICING RISKS

Inaccurate consumption or collection forecasting might reduce scheduled payments on the bonds

The fixed recovery charges are assessed based on forecasted customer usage. The amount and the rate of fixed recovery charge collections will
depend in part on actual electricity consumption and the amount of

collections and write-offs. The fixed recovery charges are calculated by the servicer according to the methodology approved in the financing order, which includes the allocation of cost responsibility among FRC consumer classes based upon the allocation methodology. If the servicer inaccurately forecasts either electricity consumption or underestimates customer delinquency or write-offs when setting or adjusting the fixed recovery charge, there could be a shortfall or material delay in fixed recovery charge collections, which might result in missed or delayed payments of principal and interest and lengthened weighted average life of the bonds. Please read “ SCE’s Financing Order—Fixed Recovery Charges—The Financing Order Establishes the Methodology used to Calculate the Fixed Recovery Charges” and “ The Servicing Agreement—The True-UpAdjustment Letters” in this prospectus. Inaccurate forecasting of electricity consumption by the servicer might result from, among other things:

| • |     | unanticipated weather or economic conditions, resulting in less electricity consumption than forecast; |

| • |     | general economic conditions, causing customers to migrate from SCE’s service territory or reduce their 
 electricity consumption;                                                                               |

| • |     | the occurrence of a natural disaster, such as wildfires or earthquakes or an act of war or terrorism, or other            
 catastrophic event, including pandemics, unexpectedly disrupting electrical service and reducing electricity consumption; |

| • |     | unanticipated changes in the market structure of the electric industry; |

| • |     | large customers unexpectedly ceasing business or departing SCE’s service territory; |

| • |     | dramatic and unexpected changes in energy prices resulting in decreased electricity consumption; |

| • |     | customers consuming less electricity than anticipated because of increased energy prices, unanticipated increases 
 in conservation efforts or unanticipated increases in electric consumption efficiency;                            |

| • |     | implementation of new billing systems and other customer-facing technology; |

| • |     | differences or changes in forecasting methodology; or |
