Customer Base and Energy Consumption

The following tables show the electricity usage billed to customers, electric billed revenues and number of customers for each revenue-reporting customer class for the five preceding years within Oklahoma. There can be no assurances that the retail electricity sales, retail electric revenues and number of retail customers or the composition of any of the foregoing will remain at or near the levels reflected in the following tables.

The Service Level of each customer is determined by OG&E based on the nominal standard voltage of such customer’s connection to the OG&E electric transmission and distribution system. Securitization Charge allocations are based on the actual daily kWh usage for each service level for the period of emergency during Winter Storm Uri, February 7, 2021 to February 21, 2021.

Percentage Concentration Within Large Commercial Customers

For the year ended December 31, 2025, the ten largest customers represented approximately 23.2 percent of total energy usage in Oklahoma and approximately 13.8 percent of OG&E’s total revenues in Oklahoma. All ten customers are commercial, industrial, oilfield and public authority class accounts. There are no material concentrations in the residential class.

Credit Policy

OG&E's current business practice requires new business customers to provide a security deposit in the form of cash, bond or irrevocable letter of credit that is refunded when the account is closed or when certain requirements are met. New residential customers whose outside credit scores indicate an elevated risk are required to provide a security deposit that is refunded based on customer protection rules promulgated by the OCC. The payment behavior of all existing customers is continuously monitored, and, if the payment behavior indicates sufficient risk within the meaning of the applicable utility regulation, customers will be required to provide a security deposit.

Billing Process

OG&E bills its customers on average every 30 days. For the year ended December 31, 2025, OG&E mailed out an average of 39,523 bills on each business day to its customers. For accounts with potential billing error exceptions, reports are generated for manual review. This review examines accounts that have abnormally high or low bills, potential meter-reading errors, possible meter malfunctions and/or unbilled accounts.

Collection, Termination of Service and Write-Off Policy

OG&E receives approximately 15 percent of its total bill payments via U.S. mail. Approximately 85 percent of bill payments are received via electronic payments. Bills are due 21 calendar days after the issue date at which time they are considered delinquent. Delinquent customers are sent a notice to encourage payment within ten days and accounts become eligible for disconnect after the passage of these ten days. For the year ended December 31, 2025, approximately 2.19 percent of total billed retail revenue became eligible for disconnect and 46.0 percent of those eligible were disconnected. Approximately 88.1 percent of accounts disconnected for nonpayment ultimately make full payment and have service restored.

If service is terminated, the customer is required to pay all past due amounts as well as a $21 reconnection fee in order to resume service as of the date of this official statement. After service termination due to non-payment a final bill including all unpaid amounts and net of deposits paid is issued within ten business days. After service termination by customer request, a final bill including all unpaid amounts and net of deposits paid is issued the following business day. Unpaid final bills are written off approximately 180 days after the final bill is issued. Amounts written off are assigned to outside collection agencies and are reported to all three credit reporting agencies. Dollars recovered are netted against actual write-offs.

OG&E may change its credit, billing, collections and termination/restoration of service policies and procedures from time to time. It is expected that any such changes would be designed to enhance OG&E’s ability to bill and collect customer charges on a timely basis.

Annual Forecast Variance

The following table sets forth information related to annual forecast variance for ultimate electric delivery for the past five years. Variances between actual sales and forecasted sales can be caused by a number of factors, though the primary drivers are unexpected extreme temperatures, which can cause actual sales volumes to be higher or unexpected mild temperatures, which can cause actual sales volumes to be lower. For 2020 and 2021, the primary driver of variances between the forecast and actual sales volumes is changes in behavior in response to COVID.

Write-off and Delinquency Experience

The following tables set forth information relating to the total billed revenues and write-off experience for the past five years. Such historical information is presented because OG&E’s actual experience with respect to write-offs and delinquencies may be indicative of its future experience, which will affect the timing of Winter Event Charge Collections. OG&E does not expect, but there can be no certainty, that the delinquency or write-off experience with respect to Winter Event Charge Collections will differ

substantially from the rates indicated. Write-off and delinquency data is affected by factors such as the overall economy, weather and changes in collection practices. The net write-off and delinquency experience is expected, but there can be no certainty, to be similar to OG&E’s previous experience.

The following table shows total OG&E revenues for the past five calendar years for each customer class.
