(1)

A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

(2)

The Issuing Entity expects to deliver the Bonds against payment for the Bonds on or about November 12, 2026, which will be the sixth business day following the date of pricing of the Bonds. Since trades in the secondary market generally settle in one business day, purchasers who wish to trade Bonds prior to the business day prior to settlement will be required, by virtue of the fact that the Bonds initially will settle in T+6, to specify alternative settlement arrangements to prevent a failed settlement.

(3)

In any case where the date on which payment is due shall not be a Business Day, then payment may be made on the next Business Day.

(4)

Interest on the Bonds will accrue from November 12, 2026. If the Bonds are delivered after that date, the purchaser will pay accrued interest.

Assumptions

For the purposes of preparing the above chart, the following assumptions, among others, have been made: (i) in relation to the initial forecast, the forecast error stays constant over the life of the Bonds and is equal to an overestimate of electricity consumption of 5% (1.65 standard deviations from mean) or 15% (4.70 standard deviations from mean); (ii) the Servicer makes timely and accurate filings to make True-Up Adjustments to the Securitization Charges semi-annually; (iii) customer net charge-off rates are held constant at 0.90% for all classes of Customers; (iv) all Securitization Charges are remitted 34 days after such charges are billed; (v) operating expenses are equal to projections; (vi) there is no acceleration of the applicable Final Maturity Date of the Bonds; (vii) a permanent loss of all Power Supply Customers and Distribution Customers required to pay each Securitization Charge, as the case may be, has not occurred; and (viii) the issuance date of the Bonds is November 12, 2026. There can be no assurance that the weighted average lives of the Bonds will be as shown.
