January 2024 storm and damage—Beginning January 13, 2024, the Company’s service territory encountered a severe winter weather event that included snow, ice, and high winds over several days that caused catastrophic damage to physical assets and resulted in widespread customer power outages. As a result of the historic winter storm, Oregon’s Governor declared a state of emergency on January 18, 2024, which allows PGE to seek recovery of incremental storm expenses through the OPUC pre-authorized emergency deferral mechanism, subject to the application of an earnings test. On February 9, 2024, PGE filed a Notice of Deferral with the OPUC, under Docket UM 2190, related to the emergency restoration costs for the January storm, and through September 30, 2025 the Company had deferred $47 million, including interest, under the deferral. PGE believes the amounts deferred as of September 30, 2025 are probable of recovery under the emergency deferral mechanism, and no earnings test adjustment is necessary as PGE's 2024 regulated return on equity did not exceed the OPUC's authorized rate. The Company submitted a request for recovery on July 3, 2025. The OPUC has significant discretion in making the final determination of recovery, and their conclusion of overall prudence, including application of the earnings test, could result in a portion, or all, of PGE’s deferrals being disallowed for recovery. Such disallowance would be recognized as a charge to earnings. Reliability contingency events—As approved by the OPUC in PGE’s 2024 GRC, the Reliability Contingency Event (RCE) mechanism allows PGE to defer and recover 80% of prudent costs for RCEs above amounts forecasted in the Company’s Annual Power Cost Update Tariff, without application of an earnings test, with the remaining 20% flowing through operating expenses and subject to the existing power cost adjustment mechanism (PCAM). As of September 30, 2025, PGE’s deferred balance related to RCEs was $89 million, which includes $87 million related to RCEs deferred in 2024 and $2 million related to RCEs deferred in 2025. PGE files the results of the PCAM annually with the OPUC no later than July 1, initiating a regulatory review process that typically results in a final determination and order from the OPUC by the end of the year of filing, with any resulting refund or collection impacting customer prices effective in the following year. RCE costs incurred in 2024 and in 2025 will be included in the PCAM for 2024 and 2025. The Company filed the PCAM for 2024 on July 1, 2025, and the proceeding is on-going with a Commission decision anticipated in the first quarter of 2026. The Company expects to file the PCAM for 2025 no later than July 1, 2026. PGE believes the deferred amounts as of September 30, 2025 are probable of recovery. The OPUC has significant discretion in making the final determination of recovery. The OPUC’s conclusion of overall prudence could result in a portion, or all, of PGE’s deferrals being disallowed for recovery. Such disallowance would be recognized as a charge to earnings. Wildfire Mitigation—Wildfire Mitigation represents incremental costs and investments made by PGE related to efforts on its system to mitigate the risk of wildfire and improve resiliency to wildfire damage under Oregon Senate Bill 762, enacted in 2021. These efforts include enhanced tree and brush clearing, hardening and undergrounding equipment, and making emergency plans in close partnership with various land and emergency management agencies to further expand the use of a public safety power shutoff, when the risk warrants. In December 2024, PGE submitted its 2025 risk-based Wildfire Mitigation Plan, which was reviewed and approved by the OPUC on June 26, 2025. As of September 30, 2025 and December 31, 2024, PGE’s deferred balance related to incremental wildfire mitigation operating expenses was $46 million and $43 million, respectively. The 2025 balance is comprised of: •Pre-AAC—Prior to establishing the collections noted below, PGE had deferred incremental costs related to wildfire mitigation and as of September 30, 2025 this balance was $3 million, which is expected to be fully amortized by February 28, 2026. •2023 Base rates—The outcome of PGE’s 2022 GRC provided an annual amount of $24 million to be collected in base rates for recovery of operating expenses related to wildfire mitigation efforts beginning May 9, 2022, through December 31, 2023. As of September 30, 2025, there was $1 million in the balancing account related to 2023. In February 2025, the OPUC approved an advice filing that allows for the recovery of these costs over a twelve-month period, which began March 1, 2025. •2024 AAC—Beginning January 1, 2024, and in conjunction with the Company’s 2024 GRC proceeding, PGE removed the $24 million of wildfire mitigation operations and maintenance (O&M) expense recovery from base rates, with the intent of recovering the current year forecasted O&M expense within the automatic adjustment clause (AAC) in a separate tariff. On February 16, 2024, PGE submitted an advice filing to the OPUC to update the tariff to reflect prospective wildfire mitigation costs for 2024, which included $45 million of O&M expense and $4 million for the revenue requirement of capital placed in service. On July 23, 2024, the OPUC reached a decision that allowed PGE to begin collecting $24 million of O&M expense and $4 million for the revenue requirement of capital placed in service. Collection occurred over a nine-month period, which began August 1, 2024. Although the approved amount of collections in 2024 was less than actual costs, PGE does not believe it is precluded from deferring such costs and believes they are prudently incurred and probable of recovery. Any differences between actual expense and customer collections will be recorded as regulatory assets or liabilities within the AAC balancing account, which will be subject to a prudence review, but will not be subject to an earnings test. As of September 30, 2025, there was $22 million deferred as a regulatory asset in the balancing account related to 2024. PGE submitted an additional filing to seek recovery of the remaining O&M expense on October 17, 2025. The OPUC has significant discretion in making the final determination of recovery. The OPUC’s conclusion of overall prudence could result in a portion, or all, of PGE’s deferrals being disallowed for recovery. Such disallowance would be recognized as a charge to earnings. •2025 AAC—In conjunction with PGE’s filed 2025 Wildfire Mitigation Plan, PGE submitted a series of advice filings in 2025 with the intent of recovering the $56 million related to O&M and $12 million related to the capital revenue requirement in a two-phased approach. The first phase, which includes $24 million of O&M to be collected over a twelve-month period, was approved by the OPUC in February 2025, with a tariff effective date of March 1, 2025. The second phase, which was approved by the OPUC in May 2025, will be collected over a twelve-month period beginning June 1, 2025, and includes $12 million of O&M and the entire $12 million related to capital revenue requirement. Although the OPUC has only approved a portion of PGE’s 2025 wildfire mitigation O&M, PGE does not believe it is precluded from deferring such costs. Any differences between actual expense and customer collections will be recorded as regulatory assets or liabilities within the AAC balancing account, which will be subject to a prudence review, but will not be subject to an earnings test. As of September 30, 2025, there was $20 million deferred as a regulatory asset in the balancing account related to 2025. PGE submitted an additional filing to seek recovery of the remaining 2025 forecasted O&M expense on October 17, 2025. The OPUC has significant discretion in making the final determination of recovery. The OPUC’s conclusion of overall prudence could result in a portion, or all, of PGE’s deferrals being disallowed for recovery. Such disallowance would be recognized as a charge to earnings. Clearwater RAC—The Clearwater RAC represents all costs and benefits associated with Clearwater. Under the RAC, during 2023, the Company submitted a filing for Clearwater proposing to defer the revenue requirement, net of net variable power cost (NVPC) benefits, from the in-service date of January 2024 until Clearwater was reflected in customer prices, which was March 1, 2025. For the year ended December 31, 2024, PGE deferred the revenue requirement, net of NVPC benefits resulting in a net regulatory liability of $40 million, which began amortizing as a refund to customers on March 1, 2025 over a twelve month period, as approved in OPUC Order 25-075 issued February 21, 2025. For the period of January 1, 2025 through September 30, 2025, PGE deferred an additional net $13 million regulatory liability, which remains subject to a future regulatory review, representing the deferred revenue requirement that PGE believes is probable of recovery, net of NVPC that is probable of refund to customers under the RAC for that period. The OPUC has significant discretion on overall prudence and in making the final determination of recovery or refund. Any cost disallowance or increased refunds would be recognized as a charge to earnings.

Credit Facilities On September 10, 2025, PGE entered into an amendment of its existing revolving credit facility that extended the scheduled expiration into September 2030. As of September 30, 2025, PGE had a $750 million revolving credit facility that provides t he Company the ability to expand to $850 million, if needed. Pursuant to the terms of the agreement, the revolving credit facility may be used for general corporate purposes, including as backup for commercial paper borrowings and to permit the issuance of standby letters of credit. PGE may borrow for one, three, or six months at a fixed interest rate established at the time of the borrowing, or at a variable interest rate for any period up to the then remaining term of the applicable credit facility. The revolving credit facility contains a provision that requires annual fees based on the Company’s unsecured credit ratings, and contains customary covenants and default provisions, including a requirement that limits consolidated indebtedness, as defined in the agreement, to 65% of total capitalization. As of September 30, 2025, PGE was in compliance with this covenant with a 54.5% debt-to-total capital ratio and had no outstanding balance on the revolving credit facility. The Company has a commercial paper program under which it may issue commercial paper for terms of up to 270 days. The Company has elected to limit its borrowings under the revolving credit facility in order to allow for coverage of any potential need to repay commercial paper that may be outstanding at the time. As of September 30, 2025, PGE had no commercial paper outstanding. Under the revolving credit facility, as of September 30, 2025, PGE had no borrowings outstanding and there were no letters of credit issued. As a result, the aggregate unused available credit capacity under the revolving credit facility was $750 million. PGE typically classifies borrowings under the revolving credit facility and outstanding commercial paper as Short-term debt on the condensed consolidated balance sheets. In addition, PGE h as four l etter of credit facilities that provide a total capacity of $320 million under which the Company can request letters of credit for original terms not to exceed one year. The issuance of such letters of credit is subject to the approval of the issuing institution. Under these facilities, letters of credit for a total of $169 million were outstanding as of September 30, 2025. Letters of credit issued are not reflected on the Company’s condensed consolidated balance sheets. Pursuant to an order issued by the FERC, the Company is authorized to issue short-term debt in an aggregate amount of up to $900 million through February 6, 2026. Long-term Debt On March 25, 2025, PGE entered into a Bond Purchase Agreement related to the sale of $310 million in First Mortgage Bonds (FMBs). The Bonds were issued and funded in full on March 25, 2025 and consist of: •a series, due in 2035, in the amount of $60 million that will bear interest from its issuance date at an annual rate of 5.36%; •a series, due in 2045, in the amount of $50 million that will bear interest from its issuance date at an annual rate of 5.72%; and •a series, due in 2055, in the amount of $200 million that will bear interest from its issuance date at an annual rate of 5.84%. On November 14, 2024, PGE drew a $220 million loan under a 366-day term loan agreement. On December 31, 2024, PGE repaid $50 million of the term loan and, on March 31, 2025, the Company repaid another $102 million, leaving an outstanding balance of $68 million.
