NOTE 1: BASIS OF PRESENTATION

Nature of Business

Portland General Electric Company (PGE or the Company) is a single, vertically-integrated electric utility engaged in the generation, purchase, transmission, distribution, and retail sale of electricity in the State of Oregon (State). The Company also participates in the wholesale market by purchasing and selling electricity, natural gas, and environmental credits in an effort to meet the needs of, and obtain reasonably-priced power for, its retail customers, manage risk, and administer its long-term wholesale contracts. In addition, PGE performs portfolio management and wholesale market services for third parties in the region. The Company continues to develop products and service offerings for the benefit of retail and wholesale customers. PGE operates as a single segment, with revenues and costs related to its business activities recorded and analyzed on a total electric operations basis. The Company owns unregulated, non-utility real estate comprised primarily of PGE’s corporate headquarters. The Company’s corporate headquarters is located in Portland, Oregon and its approximately 4,000 square mile, State-approved service area, entirely within the State, encompasses 51 incorporated cities. As of June 30, 2025, PGE served 956,000 retail customers within a service area of 1.9 million residents.

PGE is subject to the jurisdiction of the Public Utility Commission of Oregon (OPUC) with respect to retail prices, utility services, accounting policies and practices, issuances of securities, and certain other matters. Retail prices are based on the Company’s cost to serve customers, including an opportunity to earn a reasonable rate of return, as determined by the OPUC. The Company is also subject to regulation by the Federal Energy Regulatory Commission (FERC) in matters related to wholesale energy transactions, transmission services, reliability standards, natural gas pipelines, hydroelectric project licensing, accounting policies and practices, short-term debt issuances, and certain other matters.

Condensed Consolidated Financial Statements

These condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Certain information and note disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to such regulations, although PGE believes that the disclosures provided are adequate to make the interim information presented not misleading.

The financial information included herein as of and for the three and six months ended June 30, 2025 and 2024 is unaudited; however, in the opinion of management, such information reflects all adjustments necessary to fairly present the condensed consolidated financial position, condensed consolidated income and comprehensive income, and condensed consolidated cash flows of the Company for these interim periods. All such adjustments are of a normal recurring nature, unless otherwise noted. The financial information as of December 31, 2024 is derived from the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2024, included in Item 8 of PGE’s Annual Report on Form 10-K, filed with the SEC on February 14, 2025, which should be read in conjunction with the interim unaudited Financial Statements.

Comprehensive Income

No material change occurred in Other comprehensive income in the three and six months ended June 30, 2025 and 2024.

Use of Estimates

The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of gain or loss contingencies, as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results experienced by the Company could differ materially from those estimates.

Certain costs are estimated for the full year and allocated to interim periods based on estimates of operating time expired, benefit received, or activity associated with the interim period; accordingly, such costs may not be reflective of amounts to be recognized for a full year. Due to seasonal fluctuations in electricity sales, as well as the price of wholesale electricity and natural gas, interim financial results do not necessarily represent those to be expected for the year.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 amends Topic 740 to address requests to improve transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. For calendar year-end entities, the update will be effective for annual periods beginning on January 1, 2025. Early adoption is permitted. PGE does not expect the adoption to have a material impact on the consolidated financial statements and has not early adopted the standard.

In November 2024, the FASB issued ASU 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 requires additional disclosure, in the notes to financial statements, of specified information about certain costs and expenses. For calendar year-end entities, the update will be effective for annual periods beginning on January 1, 2027. Early adoption is permitted. PGE is assessing the impact of adoption on the consolidated financial statements and does not plan to early adopt the standard.

Reclassifications

To conform with current year presentation, the Company has reclassified Pension and other post retirement benefits of $3 million to Other non-cash income and expenses in the operating activities section of the consolidated statements of cash flows for the six-months ended June 30, 2024.

NOTE 2: REVENUE RECOGNITION

Disaggregated Revenue

The following table presents PGE’s revenue, disaggregated by customer type (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,

Other operating revenues	21		19		42		32
Total revenues	$	807	$	758	$	1,735	$	1,687

* Wholesale revenues include $30 million and $32 million related to electricity commodity contract derivative settlements for the three months ended June 30, 2025 and 2024, respectively, and $80 million and $120 million for the six months ended June 30, 2025 and 2024. Price risk management derivative activities are included within total revenues but do not represent revenues from contracts with customers as defined by GAAP. For further information, see Note 5, Risk Management.

Retail Revenues

The Company’s primary revenue source is the sale of electricity to customers at regulated, tariff-based prices. Retail customers are classified as residential, commercial, or industrial. Residential customers include single-family housing, multiple-family housing (such as apartments, duplexes, and town homes), manufactured homes, and small farms. Residential demand is sensitive to the effects of weather, with demand highest during the winter heating and summer cooling seasons. Commercial customers consist of non-residential customers who accept energy deliveries at voltages equivalent to those delivered to residential customers and are also sensitive to the effects of weather, although to a lesser extent than residential customers. Commercial customers include most businesses, small industrial companies, and public street and highway lighting accounts. Industrial customers consist of non-residential customers who accept delivery at higher voltages than commercial customers. Demand from industrial customers is primarily driven by economic conditions, with weather having a less significant impact on energy use by this customer class.

In accordance with state regulations, PGE’s retail customer prices are based on the Company’s cost of service and determined through General Rate Case (GRC) proceedings and various tariff filings with the OPUC. Additionally, the Company offers pricing options that include a daily market price option, various time-of-use options, and several renewable energy options.

11

PORTLAND GENERAL ELECTRIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS, continued

(Unaudited)

Retail revenue is billed based on monthly meter readings taken at various cycle dates throughout the month. At the end of each month, PGE estimates and records the revenue earned from energy deliveries that have not yet been billed to customers. This amount, which is classified as unbilled revenues and included in Accounts receivable, net in the Company’s condensed consolidated balance sheets, is calculated based on actual net retail system load each month, the number of days from the last meter read date through the last day of the month, and current customer prices.

PGE’s obligation to sell electricity to retail customers generally represents a single performance obligation representing a series of distinct services that are substantially the same and have the same pattern of transfer to the customer that is satisfied over time as customers simultaneously receive and consume the benefits provided. PGE applies the invoice method to measure its progress towards satisfactorily completing its performance obligations.

Pursuant to regulation by the OPUC, PGE is mandated to maintain several tariff schedules to collect funds from customers for programs that benefit the general public, such as conservation, low-income housing, energy efficiency, renewable energy programs, and privilege taxes. For such programs, PGE generally collects the funds and remits the amounts to third party agencies that administer the programs. In these arrangements, PGE is considered to be an agent, as PGE’s performance obligation is to facilitate a transaction between customers and the administrators of these programs. Therefore, such amounts are presented on a net basis and do not appear in Revenues, net within the condensed consolidated statements of income and comprehensive income.

Alternative Revenues programs—Revenues related to PGE’s decoupling mechanism and Renewable Adjustment Clause (RAC) are considered earned under alternative revenue programs, as these amounts represent contracts with the regulator and not with customers. Such revenues are presented separately from revenues from contracts with customers and classified as Alternative revenue programs, net of amortization on the condensed consolidated statements of income and comprehensive income. The activity within this line item is comprised of current period deferral adjustments, which can either be a collection from or a refund to customers, and is net of any related amortization. When amounts related to alternative revenue programs are ultimately included in prices and customer bills, the amounts are included within Revenues, net, with an equal and offsetting amount of amortization recorded on the Alternative revenue programs, net of amortization line item. Under the RAC, in 2024 and through February 28, 2025, the Company deferred amounts related to the Clearwater Wind Development (Clearwater). For further information, see “Clearwater RAC” in the Regulatory Assets and Liabilities section of Note 3, Balance Sheet Components.

Wholesale Revenues

PGE participates in the wholesale electricity marketplace in order to balance its supply of power to meet the needs of, and secure reasonably-priced power for, its retail customers, manage risk, and administer its current long-term wholesale contracts. In addition, the Company performs portfolio management and wholesale market services for third parties in the region and sells environmental credits in the wholesale marketplace. Interconnected transmission systems in the western United States serve utilities with diverse load requirements and allow PGE to purchase and sell electricity within the region depending upon: i) the relative price and availability of power; ii) hydro, solar and wind conditions; and iii) daily and seasonal retail demand.

PGE’s Wholesale revenues consist primarily of short-term electricity sales to utilities and power marketers that consist of single performance obligations that are satisfied as energy is transferred to the counterparty. The Company nets certain purchase and sale transactions in which it would simultaneously receive and deliver physical power with the same counterparty; in such cases, only the net amount of those purchases or sales required to meet retail and wholesale obligations will be physically settled and recorded in Wholesale revenues.

(Unaudited)

Other Operating Revenues

Other operating revenues consist primarily of gains and losses on the sale of natural gas volumes purchased that exceeded what was needed to fuel the Company’s generating facilities, as well as revenues from transmission services, excess transmission capacity resales, excess fuel sales, utility pole attachment revenues, and other electric services provided to customers.

Arrangements with Multiple Performance Obligations

Certain contracts with customers, primarily wholesale, may include multiple performance obligations. For such arrangements, PGE allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers.

NOTE 3: BALANCE SHEET COMPONENTS

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 June 30, 2025 the Company had deferred $47 million, including interest, under the deferral. PGE's 2024 regulated return on equity, based on actual results, did not exceed the OPUC's authorized rate. PGE believes the full amounts deferred as of June 30, 2025 are probable of recovery under the emergency deferral mechanism. 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 June 30, 2025, PGE’s deferred balance related to RCEs was $95 million, which includes $92 million related to RCEs deferred in 2024 and $3 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 April 1 of 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 expects to file the PCAM for 2025 no later than July 1, 2026. PGE believes the deferred amounts as of June 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 June 30, 2025 and December 31, 2024, PGE’s deferred balance related to incremental wildfire mitigation operating expenses was $44 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 June 30, 2025 this balance was $4 million, which is expected to be fully amortized by September 30, 2025.

•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 June 30, 2025, there was $1 million in the balancing account. 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 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 automatic adjustment clause balancing account, which will be subject to a prudence review, but will not be subject to an earnings test. As of June 30, 2025, there was $22 million deferred as a regulatory asset in the balancing account. PGE anticipates submitting an additional filing to seek recovery of the remaining O&M expense in the fourth quarter of 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 automatic adjustment clause balancing account, which will be subject to a prudence review, but will not be subject to an earnings test. As of June 30, 2025, there was $17 million deferred as a regulatory asset in the balancing account. PGE anticipates submitting an additional filing to seek recovery of any potential incremental O&M expense in the fourth quarter of 2025 to align with PGE’s total O&M expense outlined in the 2025 Wildfire Mitigation Plan. 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 February 28, 2025, PGE deferred an additional net $7 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, 2024, PGE entered into an amendment of its existing revolving credit facility that extended the scheduled expiration into September 2029. As of June 30, 2025, PGE had a $750 million revolving credit facility that provides the 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 June 30, 2025, PGE was in compliance with this covenant with a 55.1% debt-to-total capital ratio and had no outstanding balance on the revolving credit facility. As a result of the policy to backup commercial paper borrowings, the aggregate unused available credit capacity under the credit facility was $750 million.

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 June 30, 2025, PGE had no commercial paper outstanding.

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 has four letter 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 $146 million were outstanding as of June 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.

Defined Benefit Retirement Plan Costs

NOTE 4: FAIR VALUE OF FINANCIAL INSTRUMENTS

PGE estimated the fair value of financial asset and liability instruments as of June 30, 2025 and December 31, 2024, and classified these financial instruments based on a fair value hierarchy that is applied to prioritize the inputs to the valuation techniques used to measure fair value. The three levels of the fair value hierarchy and application to the Company are:

Level 1	Quoted prices are available in active markets for identical assets or liabilities as of the measurement date;
Level 2	Pricing inputs include those that are directly or indirectly observable in the marketplace as of the measurement date; and
Level 3	Pricing inputs include significant inputs that are unobservable for the asset or liability.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of assets, liabilities, and their placement within the fair value hierarchy. Assets measured at fair value using net asset value (NAV) as a practical expedient are not categorized in the fair value hierarchy. These assets are listed in the totals of the fair value hierarchy to permit the reconciliation to amounts presented in the financial statements.

Changes to market liquidity conditions, the availability of observable inputs, or changes in the economic structure of a security marketplace may require transfer of the securities between levels.

The Company’s financial assets and liabilities whose values were recognized at fair value in the Company’s condensed consolidated balance sheets are as follows by level within the fair value hierarchy (in millions):

Cash equivalents are highly liquid investments with maturities of three months or less at the date of acquisition and primarily consist of money market funds. Such funds seek to maintain a stable NAV and are comprised of short-term, government funds. Policies of such funds require that the weighted average maturity of securities holdings of such funds not exceed 90 days and provide investors with the ability to redeem shares of the funds daily at their respective NAV. Cash equivalents are classified as Level 1 in the fair value hierarchy due to the availability of quoted prices for identical assets in an active market as of the measurement date. Principal markets for money market fund prices include published exchanges such as the National Association of Securities Dealers Automated Quotations (Nasdaq) and the New York Stock Exchange (NYSE).

Assets held in the Nuclear decommissioning trust (NDT), NQBP trust, and Paid Leave Oregon trust are recorded at fair value in PGE’s condensed consolidated balance sheets and invested in securities that are exposed to interest rate, credit, and market volatility risks. These assets are classified within Level 1, 2, or 3 based on the following factors:

Debt securities—PGE invests in highly-liquid United States Treasury securities to support the investment objectives of the trusts. These domestic government securities are classified as Level 1 in the fair value hierarchy due to the availability of quoted prices for identical assets in an active market as of the measurement date.

20

PORTLAND GENERAL ELECTRIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS, continued

(Unaudited)

Assets classified as Level 2 in the fair value hierarchy include domestic government debt securities, such as municipal debt, and corporate credit securities. Prices are determined by evaluating pricing data such as broker quotes for similar securities and adjusted for observable differences. Significant inputs used in valuation models generally include benchmark yields and issuer spreads. The external credit rating, coupon rate, and maturity of each security are considered in the valuation, as applicable.

Money market funds—PGE invests in money market funds that seek to maintain a stable NAV. These funds invest in high-quality, short-term, diversified money market instruments, short-term treasury bills, federal agency securities, certificates of deposits, and commercial paper. The Company believes the redemption value of these funds is likely to be the fair value, which is represented by the NAV. Redemption is permitted daily without written notice.

The NQBP trust is invested in exchange-traded government money market funds and is classified as Level 1 in the fair value hierarchy due to the availability of quoted prices in published exchanges such as Nasdaq and the NYSE. The money market fund in the NDT is valued at NAV as a practical expedient and is not included in the fair value hierarchy.

Assets and liabilities from price risk management activities, recorded at fair value in PGE’s condensed consolidated balance sheets, consist of derivative instruments entered into by the Company to manage its risk exposure to commodity price and foreign currency exchange rates and reduce volatility in NVPC for the Company’s retail customers. For additional information regarding these assets and liabilities, see Note 5, Risk Management.

For those assets and liabilities from price risk management activities classified as Level 2, fair value is derived using present value formulas that utilize inputs such as forward commodity prices and interest rates. Substantially all of these inputs are observable in the marketplace throughout the full term of the instrument, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace. Instruments in this category include commodity forwards, futures, and swaps.

Assets and liabilities from price risk management activities classified as Level 3 consist of longer-term commodity forwards, futures, swaps, and options for which fair value is derived using one or more significant inputs that are not observable for the entire term of the instrument.

Electricity financial futures	1		3		Discounted cash flow	Electricity forward price (per MWh)	27.00		110.00		70.55
	$	1	$	35

The significant unobservable inputs used in the Company’s fair value measurement of price risk management assets and liabilities are long-term forward prices for commodity derivatives. For certain long-term contracts, observable, liquid market transactions are not available for the duration of the delivery period. In such instances, the Company uses internally-developed long-term price curves that utilize observable data when available. When not available, regression techniques are used to estimate unobservable future prices.

The Company’s Level 3 assets and liabilities from price risk management activities are sensitive to market price changes in the respective underlying commodities. The significance of the impact is dependent upon the magnitude of the price change and PGE’s position as either the buyer or seller under the contract. Sensitivity of the fair value measurements to changes in the significant unobservable inputs is as follows:

Significant Unobservable Input	Position	Change to Input	Impact on Fair Value
Market price	Buy	Increase (decrease)	Gain (loss)
Market price	Sell	Increase (decrease)	Loss (gain)

* Both realized and unrealized losses/(gains), of which the unrealized portions are offset by the effects of regulatory accounting until settlement of the underlying transactions, are recorded in Revenues, net or Purchased power and fuel expense in the condensed consolidated statements of income and comprehensive income. Amounts include $3 million and $2 million net realized gains for the three months ended June 30, 2025 and 2024, respectively. For the six-month periods ended June 30, 2025 and 2024, amounts include $4 million in net realized gain and $1 million in net realized gains, respectively.

Transfers out of Level 3 occur when the significant inputs become more observable, such as when the time between the valuation date and the delivery term of a transaction becomes shorter.

Long-term debt is recorded at amortized cost in PGE’s condensed consolidated balance sheets. The value of the Company’s Long-term debt is classified as a Level 2 fair value measurement.

As of June 30, 2025, the carrying amount of PGE’s long-term debt was $4,731 million, net of $15 million of unamortized debt expense, and its estimated aggregate fair value was $4,251 million. As of December 31, 2024, the carrying amount of PGE’s long-term debt was $4,524 million, net of $15 million of unamortized debt expense, and its estimated aggregate fair value was $3,963 million.

NOTE 5: RISK MANAGEMENT

PGE participates in the wholesale marketplace to balance its supply of power, which consists of its own generation combined with wholesale market transactions, to meet the needs of its retail customers, manage risk, and administer the Company’s long-term wholesale contracts. Wholesale market transactions include purchases and sales of both power and fuel resulting from economic dispatch decisions with respect to Company-owned generation resources. The Company also performs portfolio management and wholesale market services for third parties in the region and purchases and sells environmental credits in the wholesale marketplace. As a result of this ongoing business activity, PGE is exposed to commodity price risk and foreign currency exchange rate risk, from which changes in prices and/or rates may affect the Company’s financial position, results of operations, or cash flows.

PGE utilizes derivative instruments to manage its exposure to commodity price risk and foreign exchange rate risk in order to reduce volatility in NVPC for its retail customers. Such derivative instruments, recorded at fair value on the condensed consolidated balance sheets, may include forwards, futures, swaps, and options contracts for electricity, natural gas, and foreign currency, with changes in fair value recorded in the condensed consolidated statements of income and comprehensive income. In accordance with ratemaking and cost recovery processes authorized by the OPUC, PGE recognizes a regulatory asset or liability to defer the gains and losses from derivative activity until settlement of the associated derivative instrument. The Company may designate certain derivative instruments as cash flow hedges or may use derivative instruments as economic hedges. PGE does not intend to engage in trading activities for non-retail purposes.

Net unrealized and certain net realized losses/(gains) presented in the table above are offset within the condensed consolidated statements of income and comprehensive income by the effects of regulatory accounting. Of the net amounts recognized in Net income for the three-month periods ended June 30, 2025 and 2024, net gains of $16 million and $5 million, respectively, have been offset. Net gains of $62 million and $54 million have been offset for the six-month periods ended June 30, 2025 and 2024, respectively.

Assuming no changes in market prices and interest rates, the following table indicates the year in which the net unrealized loss recorded as of June 30, 2025 related to PGE’s derivative activities would become realized as a result of the settlement of the underlying derivative instrument (in millions):

PGE’s secured and unsecured debt is currently rated at investment grade by Moody’s Investors Service (Moody’s) and S&P Global Ratings (S&P). Should Moody’s or S&P reduce their rating on the Company’s unsecured debt to below investment grade, PGE could be subject to requests by certain wholesale counterparties to post additional performance assurance collateral, in the form of cash or letters of credit, based on total portfolio positions with each of those counterparties. Certain other counterparties would have the right to terminate their agreements with the Company.

The aggregate fair value of derivative instruments with credit-risk-related contingent features that were in a liability position as of June 30, 2025 was $137 million, for which PGE has posted $12 million in collateral, consisting of $3 million of letters of credit and $9 million of cash. If the credit-risk-related contingent features underlying these agreements were triggered at June 30, 2025, the cash requirement to either post as collateral or settle the instruments immediately would have been $115 million. As of June 30, 2025, PGE had $27 million cash collateral posted for derivative instruments with no credit-risk-related contingent features. Cash collateral for derivative instruments is classified as Margin deposits included in Other current assets on the Company’s condensed consolidated balance sheets.

As of June 30, 2025, PGE held from counterparties $11 million in collateral, consisting of $6 million of letters of credit and $5 million of cash. The obligation to return cash collateral held for derivative instruments is included in Accrued expenses and other current liabilities on the Company’s condensed consolidated balance sheets.

PGE is exposed to credit risk in its commodity price risk management activities related to potential nonperformance by counterparties. Credit risk may be concentrated to the extent the Company’s counterparties have similar economic, industry or other characteristics and due to direct or indirect relationships among the counterparties. PGE manages the risk of counterparty default according to its credit policies by performing financial credit reviews, setting limits and monitoring exposures, and requiring collateral (in the form of cash, letters of credit, and guarantees) when needed. The Company also uses standardized enabling agreements and, in certain cases, master netting agreements, which allow for the netting of positive and negative exposures under multiple agreements with counterparties.

See Note 4, Fair Value of Financial Instruments, for additional information concerning the determination of fair value for the Company’s Assets and Liabilities from price risk management activities.

NOTE 6: EARNINGS PER SHARE

Basic earnings per share are computed based on the weighted average number of common shares outstanding during the period. Diluted earnings per share are computed using the weighted average number of common shares outstanding and the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Potential common shares consist of: i) employee stock purchase plan shares; ii) contingently issuable time-based and performance-based restricted stock units, along with associated dividend equivalent rights; and iii) shares issuable pursuant to the at-the-market offering program. See Note 7, Shareholders’ Equity, for additional information on the at-the-market offering program and the resulting impact on earnings per share. Unvested performance-based restricted stock units and associated dividend equivalent rights are included in dilutive potential common shares only after the performance criteria have been met. Anti-dilutive stock awards are excluded from the calculation of diluted earnings per common share.

For the three and six months ended June 30, 2025, unvested performance-based restricted stock units and related dividend equivalent rights of 641 thousand shares were excluded from the dilutive calculation because the performance goals had not been met, with 513 thousand shares excluded for the three and six months ended June 30, 2024.

Net income is the same for both the basic and diluted earnings per share computations. The denominators of the basic and diluted earnings per share computations are as follows (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2025	2024	2025	2024
Weighted-average common shares outstanding—basic	109,522	103,034	109,473	102,167
Dilutive effect of potential common shares	243	198	252	171
Weighted-average common shares outstanding—diluted	109,765	103,232	109,725	102,338

At-the-Market Offering Program—In July 2024, PGE entered into an equity distribution agreement under which it could sell up to $400 million of its common stock through at-the-market offering programs. In the fourth quarter of 2024 the Company entered into forward sale agreements for 1,420,049 shares. In December 2024, the Company issued 1,066,549 shares pursuant to the forward sale agreements and received net proceeds of $50 million. The Company entered into forward sale agreements for 1,996,890 shares and 1,707 shares in the first quarter and the second quarter of 2025, respectively. The Company could have physically settled the remaining amount by delivering 2,352,097 shares in exchange for cash of $104 million as of June 30, 2025. Any proceeds from the issuances of common stock will be used for general corporate purposes and investments in renewables and non-emitting dispatchable capacity.

Prior to settlement, the potentially issuable shares pursuant to the agreements may be reflected in PGE’s diluted earnings per share calculations using the treasury stock method. Under this method, the number of shares of PGE’s common stock used in calculating diluted earnings per share for a reporting period would be increased by the number of shares, if any, that would be issued upon physical settlement of the agreements less the number of shares that could be purchased by PGE in the market with the proceeds received from issuance (based on the average market price during that reporting period). Share dilution occurs when the average market price of PGE’s stock during the reporting period is higher than the average forward sale price during the reporting period. As of the three and six months ended June 30, 2025, no shares were included in the calculation of diluted EPS related to the securities under the agreements. For additional information concerning the Company’s diluted earnings per share, see Note 6, Earnings Per Share.

NOTE 8: CONTINGENCIES

PGE is subject to legal, regulatory, and environmental proceedings, investigations, and claims that arise from time to time in the ordinary course of its business. Contingencies are evaluated using the best information available at the time the condensed consolidated financial statements are prepared. Legal costs incurred in connection with loss contingencies are expensed as incurred. The Company may seek regulatory recovery of certain costs that are incurred in connection with such matters, although there can be no assurance that such recovery would be granted.

Loss contingencies are accrued, and disclosed if material, when it is probable that an asset has been impaired or a liability incurred as of the financial statement date and the amount of the loss can be reasonably estimated. If a reasonable estimate of probable loss cannot be determined, a range of loss may be established, in which case the minimum amount in the range is accrued, unless some other amount within the range appears to be a better estimate.

A loss contingency will also be disclosed when it is reasonably possible that an asset has been impaired, or a liability incurred, if the estimate or range of potential loss is material. If a probable or reasonably possible loss cannot be reasonably estimated, then PGE: i) discloses an estimate of such loss or the range of such loss, if the Company is able to determine such an estimate; or ii) discloses that an estimate cannot be made and the reasons why the estimate cannot be made.

If an asset has been impaired or a liability incurred after the financial statement date, but prior to the issuance of the financial statements, the loss contingency is disclosed, if material, and the amount of any estimated loss is recorded in either the current or the subsequent reporting period, depending on the nature of the underlying event.

PGE evaluates, on a quarterly basis, developments in such matters that could affect the amount of any accrual, as well as the likelihood of developments that would make a loss contingency both probable and reasonably estimable. The assessment as to whether a loss is probable or reasonably possible, and as to whether such loss or a range of such loss is estimable, often involves a series of complex judgments about future events. Management is often unable to estimate a reasonably possible loss, or a range of loss, particularly in cases in which: i) the damages sought are indeterminate or the basis for the damages claimed is not clear; ii) the proceedings are in the early stages;

iii) discovery is not complete; iv) the matters involve novel or unsettled legal theories; v) significant facts are in dispute; vi) a large number of parties are represented (including circumstances in which it is uncertain how liability, if any, would be shared among multiple defendants); or vii) a wide range of potential outcomes exist. In such cases, there may be considerable uncertainty regarding the timing or ultimate resolution, including any possible loss, fine, penalty, or business impact.

EPA Investigation of Portland Harbor

An investigation by the United States Environmental Protection Agency (EPA) of a segment of the Willamette River known as Portland Harbor that began in 1997 revealed significant contamination of river sediments. The EPA subsequently included Portland Harbor on the National Priority List pursuant to the federal Comprehensive Environmental Response, Compensation, and Liability Act as a federal Superfund site. PGE has been included among more than one hundred Potentially Responsible Parties (PRPs), as it historically owned or operated property near the river.

A Portland Harbor site remedial investigation was completed pursuant to an agreement between the EPA and several PRPs known as the Lower Willamette Group (LWG), which did not include PGE. The LWG funded the remedial investigation and feasibility study and stated that it had incurred $115 million in investigation-related costs. The Company anticipates that such costs will ultimately be allocated to PRPs as a part of the allocation process for remediation costs of the EPA’s preferred remedy.

The EPA finalized a feasibility study, along with the remedial investigation, and the results provided the framework for the EPA to determine a clean-up remedy for Portland Harbor that was documented in a Record of Decision (ROD) issued in 2017. The ROD outlined the EPA’s selected remediation plan for clean-up of Portland Harbor that had an undiscounted estimated total cost of $1.7 billion, comprised of $1.2 billion related to remediation construction costs and $0.5 billion related to long-term operation and maintenance costs. Remediation construction costs were estimated to be incurred over a 13-year period, with long-term operation and maintenance costs estimated to be incurred over a 30-year period from the start of construction. Stakeholders have raised concerns that the EPA’s cost estimates are understated, and PGE estimates undiscounted total remediation costs for Portland Harbor per the ROD could range from $1.9 billion to $3.5 billion. The EPA acknowledged the estimated costs were based on data that was outdated and that pre-remedial design sampling was necessary to gather updated baseline data to better refine the remedial design and estimated cost.

A small group of PRPs performed pre-remedial design sampling to update baseline data and submitted the data in an updated evaluation report to the EPA for review. The evaluation report concluded that the conditions of Portland Harbor have improved substantially with the passage of time. In response, the EPA indicated that while it would use the data to inform implementation of the ROD, the EPA’s conclusions remained materially unchanged. With the completion of pre-remedial design sampling, Portland Harbor is now in the remedial design phase, which consists of additional technical information and data collection to be used to design the expected remedial actions. Certain PRPs, not including PGE, have entered into consent agreements to perform remedial design and the EPA has indicated it will take the initial lead to perform remedial design on the remaining areas. The Company anticipates that remedial design costs will ultimately be allocated to PRPs as a part of the allocation process for remediation costs of the EPA’s preferred remedy. The entirety of Portland Harbor continues under an active engineering design phase.

PGE continues to participate in a voluntary process to determine an appropriate allocation of costs amongst the PRPs. Significant uncertainties remain surrounding facts and circumstances that are integral to the determination of such an allocation percentage, including conclusion of remedial design, a final allocation methodology, and data with regard to property specific activities and history of ownership of sites within Portland Harbor that will inform

29

PORTLAND GENERAL ELECTRIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS, continued

(Unaudited)

the precise boundaries for clean-up. It is probable that PGE will share in a portion of the costs related to Portland Harbor.

In November 2024, the EPA issued a Special Notice Letter to 60 entities, including PGE, with requirements and deadlines that may ultimately lead to litigation, in relation to Portland Harbor. The EPA recommended that recipients coordinate their response and PGE responded by letter dated May 30, 2025. Formal negotiations are anticipated to take approximately two years, concluding in fall 2026 and no later than May 2027.

Based on the above facts and remaining uncertainties in the voluntary allocation process, PGE does not currently have sufficient information to reasonably estimate the amount, or range, of its potential liability or determine an allocation percentage that would represent PGE’s portion of the liability to clean-up Portland Harbor. However, the Company may obtain sufficient information, prior to the final determination of allocation percentages among PRPs, to develop a reasonable estimate, or range, of its potential liability that would require recording of the estimate, or low end of the range. The Company’s liability related to the cost of remediating Portland Harbor could be material to PGE’s financial position.

In cases in which injuries to natural resources have occurred as a result of releases of hazardous substances, federal and state natural resource trustees may seek to recover for damages at such sites, which are referred to as Natural Resource Damages (NRD). The EPA does not manage NRD assessment activities but does provide claims information and coordination support to the NRD trustees. NRD assessment activities are typically conducted by a Council made up of the trustee entities for the site. The Portland Harbor NRD trustees consist of the National Oceanic and Atmospheric Administration, the U.S. Fish and Wildlife Service, the State, the Confederated Tribes of the Grand Ronde Community of Oregon, the Confederated Tribes of Siletz Indians, the Confederated Tribes of the Umatilla Indian Reservation, the Confederated Tribes of the Warm Springs Reservation of Oregon, and the Nez Perce Tribe.

The NRD trustees may seek to negotiate legal settlements or take other legal actions against the parties responsible for the damages. Funds from such settlements must be used to restore injured resources and may also compensate the trustees for costs incurred in assessing the damages. PGE’s portion of NRD liabilities related to Portland Harbor will not have a material impact on its results of operations, financial position, or cash flows.

The impact of costs related to EPA and NRD liabilities on the Company’s results of operations is mitigated by the Portland Harbor Environmental Remediation Account (PHERA) mechanism. As approved by the OPUC in 2017, the PHERA allows the Company to defer estimated liabilities and recover incurred environmental expenditures related to Portland Harbor through a combination of third-party proceeds, including but not limited to insurance recoveries, and, if necessary, through customer prices. The mechanism established annual prudency reviews of environmental expenditures and third-party proceeds. Annual expenditures in excess of $6 million, excluding expenses related to contingent liabilities, are subject to an annual earnings test and would be ineligible for recovery to the extent PGE’s actual regulated return on equity exceeds its return on equity as authorized by the OPUC in PGE’s most recent GRC. PGE’s results of operations may be impacted to the extent such expenditures are deemed imprudent by the OPUC or ineligible per the prescribed earnings test. The Company plans to seek recovery of any costs resulting from the EPA’s determination of liability for Portland Harbor through application of the PHERA. At this time, PGE is not collecting any Portland Harbor cost from the PHERA through customer prices.

Colstrip-Related Litigation

The Company has a 20% ownership interest in the Colstrip Units 3 and 4 coal-fired generating plant (Colstrip), which is located in the state of Montana and operated by one of the co-owners, Talen Montana, LLC. Various business disagreements have arisen amongst the co-owners regarding interpretation of the Ownership and Operation

30

PORTLAND GENERAL ELECTRIC COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS, continued

(Unaudited)

(O&O) Agreement and other matters. An arbitration process has been initiated to address such business disagreements and, along with other matters related to Colstrip, is summarized below.

Arbitration—In 2021, co-owner NorthWestern Corporation initiated arbitration against all other co-owners of Colstrip to determine whether co-owners representing 55% or more of the ownership shares can vote to close one or both units of Colstrip, or, alternatively, whether unanimous consent is required. The O&O Agreement among the parties states that any dispute shall be submitted for resolution to a single arbitrator with appropriate expertise. The parties have agreed to stay the arbitration proceedings indefinitely as settlement discussions are underway. PGE cannot predict the ultimate outcome of this matter.

Richard Burnett; Colstrip Properties Inc., et al v. Talen Montana, LLC; PGE, et al.—In 2020, the original claim was filed in the Montana Sixteenth Judicial District Court, Rosebud County, Cause No. CV-20-58. The plaintiffs alleged they suffered adverse effects from the defendants’ coal dust. In 2021, the claim was amended to add PGE as a defendant. Plaintiffs were seeking economic damages, costs and disbursements, punitive damages, attorneys’ fees, and an injunction prohibiting defendants from allowing coal dust to blow onto plaintiffs’ properties, as determined by the Court. In June 2025, PGE executed settlement and release documents that will not have a material impact on the Company’s financial position, results of operations, or cash flows.

Other Matters

PGE is subject to other regulatory, environmental, and legal proceedings, investigations, and claims that arise from time to time in the ordinary course of business that may result in judgments against the Company. Although management currently believes that resolution of such known matters, individually and in the aggregate, will not have a material impact on its financial position, results of operations, or cash flows, these matters are subject to inherent uncertainties, and management’s view of these matters may change in the future.

NOTE 9: GUARANTEES

PGE enters into financial agreements for, and purchase and sale agreements involving physical delivery of, both power and natural gas that include indemnification provisions relating to certain claims or liabilities that may arise relating to the transactions contemplated by these agreements. Generally, a maximum obligation is not explicitly stated in the indemnification provisions and, therefore, the overall maximum amount of the obligation under such indemnifications cannot be reasonably estimated. PGE periodically evaluates the likelihood of incurring costs under such indemnities based on the Company’s historical experience and the evaluation of the specific indemnities. As of June 30, 2025, management believes the likelihood is remote that PGE would be required to perform under such indemnification provisions or otherwise incur any significant losses with respect to such indemnities. The Company has not recorded any liability on the condensed consolidated balance sheets with respect to these indemnities.

NOTE 10: INCOME TAXES

Income tax expense for interim periods is based on the estimated annual effective tax rate, which includes tax credits, regulatory flow-through adjustments, and other items, applied to the Company’s year-to-date, pre-tax income. The significant differences between the Federal statutory tax rate and PGE’s effective tax rate are reflected in the following table:

	Three Months Ended June 30,				Six Months Ended June 30,
	2025		2024		2025		2024
Federal statutory tax rate	21.0	%	21.0	%	21.0	%	21.0	%
Federal tax credits*	(12.7)		(18.5)		(10.7)		(17.1)
State and local taxes, net of federal tax benefit	8.2		9.2		8.5		9.1
Flow-through depreciation and cost basis differences	(0.1)		(0.7)		(0.4)		(0.6)
Reversal of excess deferred income tax	(2.3)		(2.9)		(2.1)		(2.7)
Executive compensation	1.1		0.5		0.9		0.5
Other	1.0		0.3		0.1		(0.2)
Effective tax rate	16.2	%	8.9	%	17.3	%	10.0	%

* Federal tax credits primarily consist of production tax credits (PTCs) earned from Company-owned wind-powered generating facilities as well as amortization of investment tax credits (ITCs). PTCs are earned based on a per-kilowatt hour rate and, as a result, the annual amount of PTCs earned will vary based on weather conditions and availability of the facilities. PTCs are earned for 10 years from the in-service dates of the corresponding facilities. PGE’s PTC generation will end at various dates through 2033. The generation of production tax credits from Tucannon River Wind Farm ended in 2024. ITCs are deferred and amortized as a reduction of income tax expense over the estimated useful lives of the related properties.

Carryforwards

Federal tax credit carryforwards as of June 30, 2025 and December 31, 2024 were $77 million and $69 million, respectively. These credits primarily consist of PTCs and ITCs, which will expire at various dates through 2045. PGE included anticipated proceeds from the sale of tax credits in determining the need for a valuation allowance. PGE believes that it is more likely than not that its deferred income tax assets as of June 30, 2025 will be realized, however a valuation allowance has been recorded for the expected discount on the sale of tax credits. As of June 30, 2025 and December 31, 2024, respectively, no material valuation allowance was recorded. As of June 30, 2025, and December 31, 2024, PGE had no material unrecognized tax benefits.

NOTE 11: SEGMENT INFORMATION

Any forward-looking statement speaks only as of the date on which such statement is made and, except as required by law, PGE undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for management to predict all such factors or assess the impact of any such factor on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement.

OVERVIEW

Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is intended to provide an understanding of the business environment, results of operations, and financial condition of PGE. MD&A should be read in conjunction with the Company’s condensed consolidated financial statements contained in this report, and other periodic and current reports filed with the SEC.

PGE is a vertically-integrated electric utility engaged in the generation, transmission, distribution, and retail sale of electricity in the State of Oregon (State). The Company participates in wholesale markets by purchasing and selling electricity, natural gas, and environmental credits in an effort to meet the needs of, and obtain reasonably-priced power for, its retail customers, manage risk, and administer its long-term wholesale contracts. In addition, PGE continues to develop products and service offerings for the benefit of retail and wholesale customers. The Company generates revenues and cash flows primarily from the sale and distribution of electricity to retail customers in its service territory in the State.

Company Strategy

The Company exists to power the advancement of society. PGE energizes lives, strengthens communities, and fosters energy solutions that promote social, economic, and environmental progress. The Company is committed to being a clean energy leader and delivering steady growth and returns to shareholders. PGE is focused on working with customers, communities, policy makers, and other stakeholders to deliver affordable, safe, reliable electricity service to all, while increasing opportunities to deliver clean and renewable energy, reducing greenhouse gas (GHG) emissions, and responding to evolving customer expectations. At the same time, the Company is building an increasingly smart, integrated, and interconnected grid that spans from residential customers to other utilities within the region. PGE is transforming all aspects of its business to empower its workforce to be even more results oriented to serve customers well. To create a clean energy future, PGE is focused on the following strategic imperatives:

•Decarbonize Power—Reduce GHG emissions associated with electricity served to retail customers by at least 80% by 2030 and 100% by 2040;

•Electrify the Economy—Increase beneficial electricity use to capture the benefits of new technologies while building an increasingly clean, flexible, and reliable grid; and

•Advance Performance—Improve safety, efficiency, and system and equipment reliability while maintaining affordable energy service and growing earnings per share 5% to 7% annually.

Climate Change

State-mandated GHG emissions reduction targets—In 2021, the Oregon legislature passed House Bill (HB) 2021, establishing a 100% clean electricity by 2040 framework for PGE and other investor-owned utilities and electric service suppliers in the State. A number of provisions in the bill align with PGE’s strategic direction and highlight Oregon’s ambitious, economy-wide goals to combat climate change. The GHG emissions reduction targets

37

applicable to these regulated entities are an 80% reduction in GHG emissions by 2030, 90% by 2035, and 100% by 2040 and every year thereafter. For more information regarding HB 2021 and the baseline to which the target reductions apply, see “HB 2021” in the “Laws and Regulations” section of this Overview.

Empowering customers and communities—PGE’s customers have a desire for purchasing clean energy, as over 225 thousand residential and small commercial customers voluntarily participate in PGE’s Green Future Program, the largest renewable power program by participation in the nation. In 2017, Oregon’s most populous city, Portland, and most populous county, Multnomah, each passed resolutions to achieve 100% clean and renewable electricity by 2035 and 100% economy-wide clean and renewable energy by 2050. Other jurisdictions in PGE’s service area have similar goals and continue to consider similar goals for the future.

The Company implemented a customer subscription option, the Green Future Impact Program, which is a renewable energy program that allows large business and municipal customers to have a choice in how they source their electricity. Under the Green Future Impact Program, customers can enroll in a Customer-Supplied Option (CSO) or PGE-Supplied Option (PSO). Under the CSO, participants are responsible for finding a renewable energy facility that meets established requirements and bringing those resources to PGE. Under the PSO, customers who enrolled in Phase I can receive energy from PGE-provided purchased power agreements (PPAs) for renewable resources and customers who enroll in Phase II can receive energy either from PGE-provided PPAs for renewable resources or energy from renewable resources that are PGE owned, under certain conditions.

As of June 30, 2025, the Green Future Impact Program has an approved capacity of 750 megawatts (MW) nameplate, of which 482 MW have been subscribed. Through this voluntary program, the Company seeks to support customers’ clean energy acceleration.

Severe weather—In recent years, PGE’s service territory has experienced unprecedented heat, historic ice and snowstorms, and wildfires. In January 2024, the Company’s service territory encountered a severe winter weather event, including snow, ice, and high winds that caused catastrophic damage to physical assets and resulted in widespread customer power outages. For more information regarding the January 2024 severe winter weather event, see “Declared States of Emergency” within this Overview section. In August 2023 the region experienced a record-breaking heat wave with temperatures reaching all-time recorded highs for the month. This resulted in a peak load demand of 4,498 MW, exceeding the Company’s previous all-time peak load demand, and surpassing the prior summer peak load by nearly 6%. The increase and severity of weather events highlights the importance of combating the effects of climate change through decarbonizing the power supply and investing in a more reliable and resilient grid.

Investing in a Clean Energy Future

The Resource Planning Process—PGE’s resource planning process includes working with customers, stakeholders, and regulators to chart the course toward a clean, affordable, and reliable energy future. With the passage of HB 2021, PGE created a Clean Energy Plan (CEP), which articulates the Company’s strategy to make continued progress towards the 2030, 2035, and 2040 emission reduction targets through an equitable transition to a decarbonized grid. The CEP is based on, and was filed in connection with, the Company’s 2023 Integrated Resource Plan (IRP). PGE filed its first combined IRP and CEP with the OPUC in March 2023. That filing projected PGE’s resource and capacity needs over the next 20 years and proposed an Action Plan to meet near-term needs, subject to the new HB 2021 emissions reduction requirements.

Throughout the remainder of 2023, PGE refreshed its forecasts, first in an Addendum filed in July 2023, in OPUC Docket LC 80, then several times in subsequent comments provided to the OPUC. On January 25, 2024, the OPUC acknowledged PGE’s IRP, subject to certain conditions, providing regulatory support for the Company to pursue the

38

near-term resource additions articulated in the Action Plan. The OPUC declined to acknowledge the CEP, directing the Company in Order 24-096 to revise and resubmit certain elements of the CEP with its next CEP/IRP Update.

On June 18, 2025, PGE submitted a CEP/IRP Update to the OPUC. The Update addresses specific inputs that may have changed since the most recent IRP was acknowledged, without attempting to fully revise the IRP. This CEP/IRP Update refreshes the analysis filed with the 2023 CEP/IRP and provides status reports on actions and requirements from Order 24-096.

The CEP/IRP Update identified a new Preferred Portfolio as a result of the refreshed analysis. PGE is not proposing any changes to the Action Plan that was acknowledged within the 2023 CEP/IRP, which supports the Company's progress toward emissions targets and Preferred Portfolio resource need procurement through the 2025 All-Source Request for Proposals (RFP). This approach represents the best combination of cost, risk, community benefit, and decarbonization.

To better distinguish resource needs, the CEP/IRP Update reports the capacity from hybrid solar and battery storage resources by individual technology. This reporting change increases the stated need of the 2023 CEP/IRP Action Plan from a range of 2,700 to 3,700 MW, to an updated range of 3,500 to 4,500 MW of renewable energy and non-emitting capacity, inclusive of 2023 RFP projects, which remain under negotiation.

The actions summarized in the CEP/IRP Update will also serve as an important tool in furthering conversations with all stakeholders, and the OPUC, on PGE’s path forward to making continued progress towards emission targets while continuing to serve customers safely, reliably, and at the lowest cost possible. PGE and parties will work through the regulatory review process for the CEP/IRP Update filing (OPUC Docket LC 80) during the coming months. PGE cannot predict the ultimate outcome of the regulatory process.

2021 and 2023 All-Source RFPs

Pursuant to the 2021 All-Source RFP process, which sought approximately 1,000 MW of renewable resources and non-emitting dispatchable capacity, PGE entered into agreements to acquire resources as follows:

•Clearwater—PGE owns 208 MW of production capacity of the wind facility, located in Eastern Montana. Subsidiaries of NextEra Energy Resources, LLC, which operates the facility, owns the remaining 103 MW of production capacity and sells their portion of the output to PGE under a 30-year PPA.

•Seaside Grid—The 200 MW Battery Energy Storage System (BESS) facility, located in Portland, Oregon was placed in service on July 8, 2025 and is owned by PGE. As of June 30, 2025, the Company has recorded $340 million, including AFUDC, in construction work-in-progress (CWIP) for the Seaside Grid.

•Constable BESS (formerly Evergreen)—The 75 MW BESS facility, located in Hillsboro, Oregon was placed in service on December 20, 2024 and is owned by PGE.

•Sundial BESS (formerly Troutdale Grid)—The 200 MW BESS facility, located in Troutdale, Oregon reached commercial operations on December 20, 2024. NextEra Energy Resources, LLC owns the resource and sells the capacity to PGE under a 20-year agreement.

The agreements related to Clearwater and all BESS agreements represent the final procurement from the 2021 All-Source RFP. Resources required to meet the remaining 2030 need are anticipated to be procured through future acquisition processes, including, but not limited to, the 2023 All-Source RFP and future RFPs.

The BESS facilities qualify for federal investment tax credits (ITCs). The agreements related to Clearwater qualify for production tax credits (PTCs) and are eligible under Oregon’s Renewable Portfolio Standard (RPS) .

39

PGE filed notice with the OPUC in January 2023 that an RFP was needed to procure resources to meet forecasted capacity shortfalls and to make continued progress toward decarbonization targets under HB 2021. These actions were consistent with the 2023 IRP Action Plan. PGE filed the draft 2023 All-Source RFP with the OPUC in May 2023 and regulatory approval was granted in January 2024. The Company issued the 2023 All-Source RFP to market in February 2024, seeking bids for resources that can provide non-emitting dispatchable capacity and renewable generation.

After a robust and competitive bidding process performed in accordance with Oregon's competitive bidding rules, and with the active participation of, and oversight by, an OPUC-selected third-party independent evaluator, on September 17, 2024, PGE submitted a request for acknowledgement of the final shortlist of bidders to the OPUC. The final shortlist was acknowledged by the OPUC, with conditions, on November 19, 2024.

Following passage of House Resolution 1, the One Big Beautiful Bill Act (OBBB), on July 4, 2025, PGE plans to provide an opportunity for all conforming 2023 RFP bidders to refresh their pricing. PGE, in collaboration with an independent evaluator, will work to update scoring and ranking to reflect pricing changes from bidders in the coming months.

PGE continues to expect finalization of contracts from the 2023 RFP in the second half of 2025, with projects in service by the end of 2027. See “The One Big Beautiful Bill Act” section in this Overview for information regarding the impact of OBBB on the RFP process.

Additional details of the 2023 RFP (OPUC Docket UM 2274) are available on the OPUC website at www.oregon.gov/puc.

Both the 2021 and 2023 RFPs were the subject of regulatory and legal challenges initiated by NewSun Energy LLC, focused on the scoring methodology of the RFPs and OPUC acknowledgement of the final shortlists. Two of NewSun’s challenges to the 2021 RFP were dismissed as moot in recent court decisions. Although NewSun filed for review by the Oregon Supreme Court, in both cases the petitions for review were denied. PGE has joined the proceedings as an intervenor, and the remaining challenges are in various stages of litigation or regulatory review. PGE cannot predict the outcome of these proceedings or potential impact, if any, on its 2021 and 2023 All-Source RFP process.

NewSun was an intervenor in the Clearwater RAC proceeding in Docket UE 427, in which the OPUC rejected NewSun’s proposals to change the RFP oversight process, but adopted conditions proposed by OPUC staff on how PGE should recognize Clearwater’s capacity factor and transmission assumptions in its AUT and PCAM beginning in 2025. PGE sought and received clarification of the OPUC’s February 21, 2025 order (Order 25-075) adopting the conditions, in Order 25-223, which granted certain of PGE’s requests and denied others. PGE has a Petition for Judicial Review of Order 25-075 pending at the Oregon Court of Appeals. PGE cannot predict the outcome or potential impact, if any, on future RFP, AUT, or PCAM proceedings.

2025 All-Source RFP

PGE filed notice with the OPUC in November 2024 that an RFP in 2025 was needed to procure resources to meet a forecasted 2029 capacity shortfall and to make continued progress toward decarbonization targets under HB 2021. These actions were consistent with the 2023 IRP Action Plan and CEP Update. PGE filed the draft 2025 All-Source RFP on April 17, 2025.

Following the enactment of the OBBB and related executive orders in July 2025, PGE continues to evaluate the potential impact of these federal tax credit changes on project economics and overall portfolio cost. Loss of tax credit availability could increase renewable project costs and corresponding customer prices. In response, PGE

40

incorporated additional information requirements into the RFP to better assess tax credit eligibility, supply chain risks, and cost implications. Further detail on the federal policy changes and associated risks is provided in "The One Big Beautiful Bill Act” section in this Overview.

PGE received regulatory approval of the 2025 All Source RFP with modifications from the OPUC on July 22, 2025 and expects to issue to market in the third quarter of 2025.

Transmission Upgrades

In alignment with local and regional transmission plans, the 2023 IRP Action Plan, and CEP Update, PGE is evaluating and implementing upgrades to existing transmission resources and expansions of current transmission networks. Transmission resource actions are intended to alleviate congestion, improve regional adequacy and reliability, enable decarbonization goals, and address growing customer demand.

In May 2024, PGE signed a non-binding memorandum of understanding in the development of the North Plains Connector, an approximately 415-mile, high-voltage direct-current (HVDC) transmission line to be constructed with endpoints near Bismarck, North Dakota and Colstrip, Montana. The parties entered negotiations with the United States Department of Energy (U.S. DOE) to finalize the project objectives, terms, and conditions, including the Company’s participation, which is expected to involve a 20% ownership share of the approximately $3.2 billion total investment of the project. In August 2024, the project was awarded a $700 million grant from the U.S. Department of Energy’s Grid Resilience and Innovation Partnerships (GRIP) program to further support its development and would reduce the overall total investment of the project. A portion of the GRIP funding is allocated to assess upgrades to the Colstrip Transmission System. See “Federal Grants” in this Overview for further discussion over the impacts of Federal grants and effect of Presidential executive orders.

The North Plains Connector would be the nation’s first HVDC transmission connection among three regional U.S. electric energy markets, providing additional flexibility and the sharing of resources across multiple time zones. PGE's resource planning process indicates the need for transmission to provide additional transfer capacity, access to diverse energy resources and enhanced wholesale markets, and ease congestion on the existing western transmission system. PGE continues to explore the North Plains Connector as a resource to meet those load-service needs.

The U.S. DOE selected the Confederated Tribes of Warm Springs (CTWS), with PGE as a subrecipient under the grant, for a $250 million grant to upgrade the existing 230 kV Bethel-Round Butte Transmission line to 500 kV. The project will accelerate the development of transmission capacity, enabling new generation in Central and Eastern Oregon to reach customer demand loads in Western Oregon. The added capacity and associated upgrades will also increase resiliency of the transmission system as well as resiliency of the CTWS communities by increasing resources available to the CTWS to support economic growth opportunities. See “Federal Grants” in this Overview for further discussion over the impacts of Federal grants and the potential effect of Presidential executive orders.

Building a resilient grid—To serve communities with clean energy, PGE’s grid of the future will need to be smart and adaptive. Highlights of PGE’s key investments and plans for building a resilient grid include:

•Wildfire Mitigation—PGE has a Wildfire Mitigation Program under which an annual Wildfire Mitigation Plan (WMP) is developed and submitted to the OPUC, as required by State law, to coordinate activities across the Company and with State-wide stakeholders. The 2025 WMP Update forecasts $53 to $57 million in operations and maintenance costs and an additional $57 to $78 million in capital investments, for the year ending 2025, to continue system hardening efforts, expand situational awareness capabilities, implement specific inspection and maintenance along with vegetation management, raise community and customer

41

awareness, and take operational actions within high fire risk zones. PGE strives to improve regional safety by mitigating the risk that PGE’s electric utility infrastructure could cause a wildfire, while limiting the impacts of PSPS events and other mitigation activities on customers and increasing the resiliency of PGE assets to wildfire damage. In the six months ended June 30, 2025, PGE invested $24 million in capital projects related to wildfire mitigation and resiliency and utility asset management, consistent with the 2025 WMP Update.

•Virtual Power Plant (VPP)—PGE’s VPP is comprised of Distributed Energy Resources and flexible loads that are managed through technology platforms to provide grid and power operations services. PGE’s customer offerings related to flexible load programs, rooftop solar, battery storage, and electric vehicle (EV) charging solutions support grid reliability and increase portfolio flexibility and resource diversity. These Distributed Energy Resources and flexible loads are the foundation of PGE’s VPP that increasingly provides a growing suite of grid and system services over time. When coordinated through the Company’s Distributed Energy Resources Management Systems, Distributed Energy Resource and flexible loads support cost-effective decarbonization, advance customer and community energy resiliency, promote customer engagement with the energy system, and unlock additional grid services that enhance PGE’s operation of a dynamic two-way system. As customer participation in PGE’s VPP grows, their actions provide increasing benefit and help avoid customer service interruptions and reduce exposure to scarcity pricing in energy markets.

•Distribution System Plan (DSP)—In 2021 and 2022, PGE filed its inaugural DSP in two parts, which were accepted by the OPUC in March 2022 and February 2023, respectively. The OPUC Staff finalized their review of modifications to the current DSP guidelines in the fourth quarter of 2024 and PGE filed its next DSP in December 2024, fully compliant with the updated requirements. The DSP outlines distribution system assets, describes how the Company plans for new load, including distributed resources such as EVs and rooftop solar installations, and presents the vision for modernizing the grid to enable accelerated decarbonization and customer participation in demonstrating continual progress towards PGE’s clean energy goals. For further information on recovery of costs related to the DSP, see “Distribution System Plan recovery mechanism” in the Regulatory Matters section of this Overview.

Electrify the economy—To help Oregon reach its decarbonization goals, PGE is committed to increasing electrification of buildings and supporting vehicle electrification for customers.

Transportation electrification (TE) is one of the most significant ways to reduce GHG emissions in Oregon. PGE is engaged with customers and communities to manage EV charging load, develop infrastructure projects aimed at improving accessibility to EV charging stations, build electric fleet partnerships, and offer programs to support customers’ transitions to TE.

In October 2023, the OPUC accepted PGE’s second TE plan, which covers the 2023 to 2025 time period and considers current and planned activities, along with forecasted EV loads. To date, PGE has incurred $11 million in capital expenditures under the current TE plan. PGE expects to submit its draft 2026-2028 TE plan on July 25, 2025.

PGE continues to pursue advanced technologies to enhance the grid, pursue energy storage, and develop microgrids and the use of data and analytics to better predict demand and support energy-saving customer programs.

Laws and Regulations

Trade Tariffs—Recently, trade tariffs were imposed through presidential executive orders. While some tariffs scheduled to take effect were temporarily suspended, broad tariffs remain in effect. Trade tariffs may increase the cost of imported materials and equipment, disrupt supply chains, drive economic volatility, and create adverse capital and credit market conditions. The cost of steel utility poles, meters, transformers, and specialized electrical equipment, among other items, may increase materials and supplies balances and elevate the cost of capital projects. Similarly, prices may rise and lead times may lengthen for necessary components in resources considered for acquisition in PGE’s All-Source RFPs. For further information on the Company’s RFPs, see “The Resource Planning Process” in the Investing in a Clean Energy Future section of this Overview. While PGE’s Canadian natural gas imports are not expected to be impacted by the current state of trade tariffs due to the imports being U.S.-Mexico-Canada Agreement compliant, the future of trade tariff impacts on such imports is uncertain. The Company is unable to reasonably estimate the effects of the rapidly evolving trade tariff landscape, as those effects could include project delays and cost increases, and present obstacles to PGE’s strategic plan execution. PGE is closely monitoring the impacts of trade tariffs and the potential effect they may have on the Company’s financial position, results of operations, or cash flows.

Federal Grants—In November 2021, the $1.2 trillion Infrastructure Investment and Jobs Act (IIJA), which includes approximately $550 billion of new federal spending, was signed into law. PGE continues to pursue multiple areas under the IIJA, and other state and federal programs, for potential grant funding of projects. These projects target improvements in electrical system reliability and resiliency, wildfire situational awareness and mitigation, greater communications capabilities, advancements in customer usage analytics using artificial intelligence, renewable resources and advanced electrical grid support, hydro generation operations, and regional transmission capacity constraints.

As of June 30, 2025, PGE has been associated with the submission of 42 grant applications as the recipient or subrecipient and has been awarded 10 grants totaling $313 million, including the following:

•U.S. DOE Bethel-Round Butte Transmission Line Upgrade—The U.S. DOE selected the CTWS, with PGE as a subrecipient under the grant, for a $250 million grant to upgrade the existing 230 kV Bethel-Round Butte Transmission Line to 500 kV. The U.S DOE and the CTWS, as the prime recipient, entered into a Cooperative Agreement on August 13, 2024. Subsequently the CTWS entered into a subrecipient agreement with PGE on December 1, 2024. These agreements memorialize the funding and scope for the multiyear transmission line upgrade. See “Transmission Upgrades” in this Overview for further discussion.

•U.S. DOE Grid Edge Devices—The U.S. DOE selected and subsequently entered into an agreement on October 1, 2024 with PGE leading a consortium for a $50 million grant for the Grid Edge Devices project. The project will enable real-time information at each meter to improve the visibility of the electrical system to grid operators, providing detection of potential operational problems and shorten outage times, ultimately helping to anticipate and mitigate the impacts of extreme weather on grid resiliency.

As of June 30, 2025, PGE has incurred an immaterial amount of costs associated with its federal grants and continues to assess the impacts of these federal grants on the Company’s financial position and results of operations. A series of Presidential executive orders were recently issued related to energy and environmental policies. These orders could lead to delays, reviews, and potential terminations or modifications of grants. PGE is analyzing these executive orders to understand their potential impact on grant funding, and associated work that was originally required as a part of certain Community Benefits Plans. As of June 30, 2025, the grants disclosed above continue to be executed. Although PGE continues to apply for additional grants, the Company cannot predict the ultimate timing and success of securing funding from federal programs, or predict the outcome of existing grants.

Inflation Reduction Act of 2022—The IRA was signed into law in August 2022 with a majority of the provisions effective for tax years beginning after December 31, 2022.

43

The United States Treasury and the Internal Revenue Service released extensive rules addressing credit transfer eligibility and application, including but not limited to, required registration, filing, and documentation for transferors and transferees to elect and claim a credit transfer. In December 2023, PGE received approval from the OPUC to transfer 2023 PTCs and record any difference in the full value and the discounted value in a property balancing account. Consistent with options available under the IRA, the Company transferred 2023 credits with the final transfer occurring in the first quarter of 2024. On April 17, 2024, PGE received approval from the OPUC to transfer 2024 and 2025 PTCs and record any difference between the full value and the discounted value in a property balancing account. On December 11, 2024, PGE received approval from the OPUC to transfer 2024 ITCs and return the net proceeds from the sale to PGE customers. PGE has entered into agreements to transfer 2023 through 2025 tax credits and transferred $13 million and $112 million, net of discounts, for cash proceeds in the first half of 2025 and in 2024, respectively. The Company expects to generate and transfer approximately $168 million in tax credits in 2025.

The Company believes the tax incentives in the IRA provide additional investment opportunities for PGE and provide benefits to customers. Increased capital expenditures in such investment opportunities would likely result in additional financing needs through debt and equity instruments.

The One Big Beautiful Bill Act—On July 4, 2025, the President signed the OBBB, which materially amends or repeals several renewable-energy tax incentives that were originally enacted under the IRA. It is expected that projects currently under construction and intended to be placed in service this year will remain eligible for the PTC or ITC amounts already reflected in balances; therefore, no adjustment was recorded in the quarter ended June 30, 2025. The transferability of tax credits, as provided under the IRA, also remains in effect. A July 7, 2025 executive order has added uncertainty with respect to the specific actions necessary to demonstrate a project’s start of construction. Further clarity is expected from the Secretaries of the Treasury and the Interior as it relates to their findings and actions taken under this executive order within 45 days.

The accelerated placed-in-service deadline for wind and solar, earlier phase-down for other technologies, and repeal of the permanent 10% ITC may reduce or eliminate the availability of renewable-energy credits on future projects. The Company cannot yet reasonably estimate the impact on PGE’s results of operations, financial position, and cash flows or on future capital expenditures, deferred-tax assets, current and future All-Source RFPs, and customer prices.

See “The Resource Planning Process” in this Overview for information regarding the impact of OBBB on the RFP process.

HB 2021—Among other things, HB 2021 requires retail electricity providers to reduce GHG emissions associated with serving Oregon retail electricity consumers to certain targets: 80% reduction by 2030; 90% by 2035; and 100% by 2040, compared to a baseline emission level. The baseline emission level is calculated for each provider by using average annual emissions associated with power generated and purchased for retail load for the years 2010 through 2012, which provide a representative sample of various hydroelectric production years.

HB 2021 requires utilities to develop a CEP for meeting the reduction targets, concurrent with each IRP. In reviewing a CEP, the OPUC must ensure that utilities take action as soon as practicable that facilitates rapid reduction of GHG emissions, demonstrate continual progress toward meeting the targets, and create a plan that is in the public interest. Further, the CEP must result in an affordable, reliable, and clean electric system. The law does not require particular GHG percentage reductions be attained until 2030. The law contains a cost cap and reliability related provisions that can slow or pause compliance with the GHG targets, if implicated. The OPUC has a current open docket, UM 2273, in which provisions regarding the cost cap are being investigated.

44

A separate law adopted in 2009 requires retail electricity providers to report annually to the Oregon Department of Environmental Quality (ODEQ) the GHG emissions associated with electricity used to serve retail customers. The OPUC must use the data reported to the ODEQ to determine whether the GHG targets have been met.

RPS standards and related laws—In 2016, Oregon Senate Bill (SB) 1547 increased the 2007 benchmarks for the percentage of electricity that must come from renewable sources by dates certain and required the elimination of coal as a fuel for generation of electricity used to serve Oregon utility customers no later than 2030.

The Company has a 20% ownership share in Colstrip and, in response to SB 1547, has accelerated depreciation of Colstrip to December 31, 2025. In order to meet PGE’s regulatory, legislative, and reliability requirements, the Company continues to evaluate the continuation of its ownership in Colstrip. See Note 8, Contingencies, in the Notes to Condensed Consolidated Financial Statements in Item 1.—“Financial Statements” for information regarding legal proceedings related to Colstrip.

Any reduction in generation from Colstrip has the potential to provide additional capacity availability on the Colstrip transmission facilities, which stretch from eastern Montana to near the western end of that state to serve markets in the Pacific Northwest and neighboring states. PGE has an approximate 15% ownership interest in, and capacity on, the Colstrip transmission facilities. See “Investing in a Clean Energy Future” in this Overview for information regarding development in eastern Montana.

Other provisions of SB 1547:

•establish RPS thresholds of 27% by 2025, 35% by 2030, 45% by 2035, and 50% by 2040, for the percentage of electricity that must come from renewable sources;

•limit the life of renewable energy credits (RECs) generated from facilities that become operational after 2022 to five years, but continue unlimited lifespan for all existing RECs and allow for the generation of additional unlimited RECs for a period of five years for projects online before December 31, 2022; and

•provide opportunity to pursue recovery of energy storage costs related to renewable energy in the Company’s Renewable Adjustment Clause (RAC) filings.

PGE expects to meet the 2025 RPS threshold.

HB 3179—The Oregon Legislature in 2025 passed HB 3179 aimed at making energy bills more affordable and transparent for customers. Under the provisions of the legislation, which still awaits the Governor’s signature, the OPUC shall balance the interests of the utility investor and the consumer by considering the cumulative economic impact of the proposed price or schedule of prices on the electric or natural gas company’s residential customers. Electric or natural gas companies are required to file a multiyear rate plan on a regular interval that is no less than three and no more than seven years long. The OPUC shall require each electric and natural gas company to, at least annually, file with the OPUC, and make publicly available, a report on any price adjustments that the electric or natural gas company expects within the next 12 months. Such report must identify all price adjustment requests that an electric or natural gas company has filed or reasonably knows or anticipates to file. Any increase in residential prices may not take effect from November 1 to March 31.

EPA Regulations for Electric Generating Facilities—In April 2024, the United States Environmental Protection Agency (EPA) released final regulations pertaining to electric generation facilities. The regulations included:

•GHG regulations for new natural gas-based turbines and existing coal-based units, pursuant to section 111 of the Clean Air Act (CAA);

45

•Supplemental Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category (the ELG Rule), which applied to wastewater discharges from coal-based generating units and established pollution control requirements, building upon the 2015 and 2020 ELG Rules; and

•Updated Mercury and Air Toxics Standards (MATS), pursuant to section 112 of the CAA, which set emissions limits for filterable particulate matter for coal-based generating units.

On April 8, 2025, the President issued a proclamation, Regulatory Relief for Certain Stationary Sources to Promote American Energy, granting a two-year compliance exemption pursuant to the CAA Section 112(i)(4) for the EPA’s MATS rule. The EPA subsequently notified companies whether their sources had been granted the exemption. Colstrip was granted an exemption until July 8, 2029.

On June 11, 2025, to advance the goals of the President’s Unleashing American Energy executive order, the EPA proposed to repeal the 2024 GHG emissions standards for fossil fuel-fired power plants promulgated under Section 111 of CAA. The EPA also proposed to repeal specific amendments to the updated MATS, that were promulgated in 2024, including the revised filterable particulate matter emissions standard. Additionally, on June 30, 2025, the EPA proposed to update the 2024 ELG Rule to extend compliance deadlines and explore flexibilities to promote reliable and affordable power generation.

PGE continues to evaluate each of these rules to assess the impact it may have on the Company’s continuing investment in Colstrip, which could be material. Compliance with the 2024 rules could require material upgrades at Colstrip with proposed compliance dates that may not be achievable or require the use of unproven technology, resulting in significant impacts to costs of Colstrip. If upheld, the 2024 MATS and GHG Rules would require compliance as early as 2027 and 2032, respectively. In addition to the EPA’s proposed rulemakings, several legal challenges have been filed regarding these rules. In challenges to all three rules, at the EPA’s request, the courts have granted stays to allow new EPA leadership to reevaluate the rule.

These challenges, or attempts by the federal government to withdraw or modify the regulations, if successful, could affect the applicability to PGE and Colstrip specifically. Given the uncertainty surrounding applicability of these laws and regulations, PGE cannot reasonably estimate the impact to its results of operations, financial position, and cash flows, however, if the MATS Rule and GHG Rule are ultimately enforced, it would likely result in additional material compliance costs. To the extent these regulations result in increased compliance costs, the Company expects to seek recovery of those costs through the ratemaking process.

Regulatory Matters

PGE focuses on providing reliable, clean power to customers at affordable prices while providing a fair return to investors. To achieve this goal the Company must execute effectively within its regulatory framework and maintain prudent management of key financial, regulatory, and environmental matters that may affect customer prices and investor returns. The following discussion provides detail on such matters.

Corporate structure—On May 23, 2025, PGE filed a notice under Oregon law with the OPUC of its intent to submit a regulatory application for approval of a holding company reorganization. On July 25, 2025, the Company expects to submit the formal application to the OPUC. PGE believes that it is in the best interests of its customers and shareholders to update its corporate structure into a holding company structure. The structure currently contemplated involves placing a non-operating corporate entity over the Company’s existing structure. Additionally, this structure would allow for the formation of a subsidiary of the holding company that could hold existing and future transmission assets. The intent of the reorganization is to take advantage of the financial flexibility provided by a holding company structure, and to support construction of new transmission assets, reliability planning, and economic development.

46

The application is another of many steps required to complete the reorganization, which needs OPUC approval under Oregon law as well as any necessary FERC approvals. Later in the process, PGE's Board of Directors will decide whether to submit the proposed reorganization to PGE shareholders for approval. Following completion of these steps and the receipt of all required approvals, each outstanding share of PGE common stock would automatically convert into a share of the new holding company (HoldCo) common stock on a one-for-one basis. PGE shareholders, immediately prior to consummation of the reorganization would own the same relative percentages of HoldCo following consummation of the reorganization. After the reorganization, PGE would be a wholly owned subsidiary of HoldCo, which would be an Oregon corporation.

Declared states of emergency—The OPUC has approved a pre-authorized deferral of costs associated with qualifying declared states of emergency, which would include federal or state declared emergencies with impacts on PGE’s service territory. Under this mechanism, PGE could provide notice of an event that qualifies within 30 days of the declared state of emergency and would not need to seek OPUC approval to apply deferred accounting treatment for incremental costs related to the emergency. The OPUC maintains responsibility to review utility requests to amortize deferred amounts in customer prices, including, among other requirements, a review of utility prudence and application of an earnings test, in a future proceeding.

In January 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 previously filed emergency deferral. On February 9, 2024, PGE filed a Notice of Deferral with the OPUC under Docket UM 2190 for emergency restoration costs related to the January storm. As of June 30, 2025, PGE had a deferred balance of $47 million, including interest, as a regulatory asset for costs associated with repairing damage to transmission and distribution systems and restoring power to customers.

PGE believes that the full amount of the deferral is probable of recovery and submitted a request for recovery early in the third quarter of 2025, with price changes to be effective over a two-year period beginning April 1, 2026. The OPUC has significant discretion in making the final determination of recovery based on its assessment of prudency and interpretation of the earnings test application, either of which could result in all, or a portion of, the deferral being disallowed. As of December 31, 2024, PGE's preliminary return on equity, based on actual results, did not exceed the OPUC's authorized rate of return. Any disallowance would be a charge to earnings, which could be material to the Company’s financial condition, results of operations, or cash flows. For further information, see “January 2024 storm and damage” in the Regulatory Assets and Liabilities section of Note 3, Balance Sheet Components in the Notes to Condensed Consolidated Financial Statements in Item 1.—“Financial Statements.”

Reliability Contingency Event (RCE)—Under the RCE mechanism, PGE is allowed to pursue recovery of 80% of costs for RCEs above amounts forecasted in the Company’s AUT, 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 June 30, 2025, PGE’s deferred balance related to RCEs was $95 million, which includes $92 million related to RCEs deferred in 2024 and $3 million related to RCEs deferred in 2025. This includes costs from multiple qualified RCEs during 2024, the most significant of which was related to the January storm event, and costs incurred during the first half of 2025. PGE filed the results of the 2024 PCAM with the OPUC on July 1, 2025, in Docket UE 457, which included a request for $86 million, without interest, in RCE costs incurred in 2024, 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. Any resulting refund or collection impacting customer prices is expected to be effective April 1, 2026. PGE believes the deferred amounts as of June 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.

47

Power costs—Pursuant to the AUT process, PGE annually files an estimate of power costs for the following year. As approved by the OPUC, the 2025 AUT included a final increase in power costs for 2025, and a corresponding increase in NVPC, of $72 million from 2024 levels, which were reflected in customer prices effective January 1, 2025.

Distribution System Plan recovery mechanism—On July 25, 2025, PGE plans to submit to the OPUC a request for recovery of costs associated with the Company’s Distribution System Plan. The regulatory filing would allow PGE the opportunity to recover its revenue requirement for these capital investments outside of a general rate case while balancing the interests of customers and PGE.

As a part of the filing, PGE requests that the Distribution System Plan Alternative Recovery Mechanism be authorized for inclusion in customer prices by April 1, 2026. PGE’s request for recovery includes an annualized revenue requirement increase of $72 million, which includes a 9.34% return on equity as approved in UE 435, and a rate base increase of $335 million.

PGE and parties will work through the regulatory review process for the Distribution System Plan Alternative Recovery Mechanism during the coming months. PGE cannot predict the ultimate outcome of the regulatory process.

Portland Harbor Environmental Remediation Account (PHERA) mechanism—The EPA has listed PGE as one of over one hundred Potentially Responsible Parties (PRPs) related to the remediation of the Portland Harbor Superfund site. As of June 30, 2025, significant uncertainties still remained concerning the precise boundaries for clean-up, the assignment of responsibility for clean-up costs, the final selection of a proposed remedy by the EPA, and the method of allocation of costs amongst PRPs. It is probable that PGE will share in a portion of these costs. In a Record of Decision (ROD) issued in 2017, the EPA outlined its selected remediation plan for clean-up of the Portland Harbor site, which had an estimated total cost of $1.7 billion. Stakeholders have raised concerns that EPA’s cost estimates are understated, and PGE estimates undiscounted total remediation costs for Portland Harbor per the ROD could range from $1.9 billion to $3.5 billion. The Company does not currently have sufficient information to reasonably estimate the amount, or range, of its potential costs for investigation or remediation of Portland Harbor. However, the Company may obtain sufficient information, prior to the final determination of allocation percentages among PRPs, to develop a reasonable estimate, or range, of its potential liability that would require recording an estimate, or low end of the range. The Company’s liability related to the cost of remediating Portland Harbor could be material to PGE’s financial position. The impact of such costs to the Company’s results of operations is mitigated by the PHERA mechanism. As approved by the OPUC, the recovery mechanism allows the Company to defer and recover estimated liabilities and incurred legal and technical analysis expenditures related to the Portland Harbor Superfund Site through a combination of third-party proceeds, including, but not limited to, insurance recoveries, and customer prices, as necessary. PGE received settlement proceeds related to Portland Harbor Superfund insurance coverage settlement agreements in the second quarter of 2025, which were deferred into the PHERA mechanism. PGE is continuing insurance recovery activity with additional insurers. The mechanism established annual prudency reviews of environmental expenditures and third-party proceeds, and annual expenditures in excess of $6 million, excluding contingent liabilities, are subject to an annual earnings test. PGE’s results of operations may be impacted to the extent such expenditures were to be deemed imprudent by the OPUC or disallowed per the prescribed earnings test. For further information regarding the PHERA mechanism, see “EPA Investigation of Portland Harbor” in Note 8, Contingencies in the Notes to Condensed Consolidated Financial Statements in Item 1.—“Financial Statements.”

Renewable recovery framework—As previously authorized by the OPUC, the RAC is a primary method available to recover costs associated with renewable resources and the inclusion of prudent costs of energy storage projects associated with renewables, under certain conditions. The RAC allows PGE to recover prudently incurred costs of renewable resources through filings made each year, outside of a GRC. In 2023, the Company filed for Clearwater,

48

which went into service in January 2024. During 2024, PGE did not submit a request for recovery of any renewable resources under the RAC and has not requested recovery of any renewable resources under the RAC during 2025, nor does it plan to do so.

Under the RAC, during 2023, the Company submitted a filing in OPUC Docket UE 427 for Clearwater proposing to defer the revenue requirement, net of NVPC benefits, from the in-service date of January 2024 until Clearwater was reflected in customer prices, which was March 1, 2025. For the twelve month period ending 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 by the OPUC in Order 25-075 issued February 21, 2025.

The OPUC’s order also adopted conditions to be applied to the AUT and clarification of the applicability of those conditions were subsequently provided by the OPUC in Order 25-223, which granted certain of PGE’s requests and denied others. PGE has a Petition for Judicial Review of Order 25-075 pending at the Oregon Court of Appeals. For the period of January 1, 2025 through February 28, 2025, PGE deferred an additional net $7 million regulatory liability, which remains subject to a future regulatory review, representing the deferred revenue requirement that the Company 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.

Seaside Grid BESS recovery - On May 30, 2025, PGE submitted with the OPUC to request recovery of the revenue requirement associated with the Seaside Battery Energy Storage System (Seaside). The regulatory filing is pursuant to the expedited cost-recovery option introduced by the OPUC in its Order issued December 20, 2024 related to PGE's 2025 General Rate Case (OPUC Docket UE 435) and would allow PGE the opportunity to recover its revenue requirement for Seaside outside of a general rate case while balancing the interests of customers and PGE.

As a part of the filing, PGE requests that the Seaside tracker be authorized for inclusion in customer prices by October 31, 2025. PGE entered into a memorandum of understanding with intervenors, which establishes the scope of recovery mechanisms for both the Seaside BESS and the DSP. The Company is committed to continuing to collaborate with key stakeholders and providing safe, reliable service at the lowest possible cost for customers.

PGE’s request for recovery includes an annualized revenue requirement increase of $46 million, cost of capital figures based on OPUC approved amounts in UE 435, which included a 9.34% return on equity, and a rate base increase of $257 million, net of estimated Investment Tax Credit benefits of $117 million.

PGE and parties will work through the regulatory review process for the Seaside tracker filing (OPUC Docket UE 455) during the coming months. PGE cannot predict the ultimate outcome of the regulatory process.

New Large Load—In December 2023, the OPUC established Docket UE 430 to investigate new load connection costs. Following a lengthy regulatory process, in December 2024, PGE filed Advice No. 24-38 with the OPUC. This filing introduced several proposed changes to PGE policies and tariffs that, if approved, would: i) reasonably protect other customers from the cost to connect new large load customers; ii) improve transmission system planning and capacity; iii) provide fair recovery of distribution investment costs from large load users; and iv) implement contractual requirements designed to appropriately allocate and recover distribution and transmission costs and mitigate the risk of stranded assets, while providing flexibility to meet large customer needs.

On April 15, 2025, the OPUC approved PGE's filing, as revised, with an effective date of April 16, 2025, on condition that the issues raised in the filing would be addressed in a new Commission docket, UM 2377. This allowed PGE to begin working with large load customers to form a load interconnection queue, conduct studies to assess and allocate connection costs, and offer study and service agreements. Any agreements with new large load

49

customers may be revised and updated based on the outcome in the separate OPUC proceeding, UM 2377, that was opened to address PGE’s proposed tariff changes and related issues.

In June 2025, the Oregon Legislature passed HB 3546 relating to large energy use facilities. HB 3546, which became effective in June 2025, directs the OPUC to provide a classification for retail customers deemed large energy use facilities. Any tariffs under the class must allocate costs to the class in a manner that is equal or proportional to the costs of serving the class, or directly assign the costs to large energy use facilities and avoid unwarranted shifting costs to other classes. HB 3546 also directs the OPUC to require that electric companies serving a large energy use facility must enter into a contract for services with such customer under terms and conditions specified by the law.

Operating Activities

In addition to providing electricity from PGE’s own generation portfolio, to meet retail load requirements and balance energy supply with customer demand, manage risk, and administer its long-term wholesale contracts, the Company purchases and sells electricity in the wholesale market. To fuel its generation portfolio, the Company purchases natural gas in the United States and Canada and sells excess gas back into the wholesale market. PGE also performs portfolio management and wholesale market sales services for third parties in the region and purchases and sells environmental credits in the wholesale marketplace.

The Company participates in the California Independent System Operator's (CAISO) western Energy Imbalance Market (EIM), which enables, among other benefits, greater integration of renewable energy onto the grid by better balancing the variable output of renewable resources. PGE signed an implementation agreement and filed tariff changes with the FERC to join the CAISO’s Extended Day-Ahead Market (EDAM), which is expected to build on the success of the western EIM and help provide the Company and its customers access to more affordable, reliable, and clean energy. The EDAM, anticipated to begin operation in 2026, will allow market participants to submit bids for their forecasted energy demand and available generation resources a day ahead of expected use. The EDAM will then optimize transmission and resource use across all market participants, enabling access to the lowest-cost resources to meet regional needs. The EDAM is expected to leverage PGE’s existing technology and systems and utilize the Company’s transmission system to connect regional resources, such as hydropower and wind facilities in the Pacific Northwest and solar facilities in California and the desert Southwest, across a unified market platform.

As part of its ongoing efforts to benefit retail and wholesale customers, PGE has also supported the Western Power Pool’s Western Resource Adequacy Program (WRAP), since 2023. The WRAP establishes a regional framework to more effectively address resource adequacy, improve reliability, integrate clean energy, and manage costs by diversifying resources and sharing capacity across a broad geographic footprint and a large pool of participants across the western United States.

PGE generates revenues and cash flows primarily from the sale and distribution of electricity to its retail customers. The impact of seasonal weather conditions on demand for electricity can cause the Company’s revenues, cash flows, and income from operations to fluctuate from period to period. Summer peak deliveries have continued to exceed those of the winter months for nearly ten years, generally resulting from growing air conditioning demand and the trend toward a warmer overall climate. In August 2023, demand reached a new all-time high, surpassing the previous mark, which was set in summer 2021. Historically, PGE had experienced its highest average megawatts (MWa) deliveries and retail energy sales during the winter heating season and recorded its current winter peak load in December 2022. Summer peak deliveries in each year since 2021 have exceeded that winter peak.

Retail customer price changes and customer usage patterns, which can be affected by the economy, also have an effect on revenues. Wholesale power availability and price, hydro and wind generation, and fuel costs for thermal plants can also affect income from operations. PGE has taken measures to enhance the availability of supply chain-

50

constrained items that are needed to serve new and existing customers, such as securing inventory of critical materials to improve reliability, reserving manufacturing capacity with strategic partners, and evaluating availability with established and new suppliers. The Company’s materials and supplies forecasting process is designed to secure materials availability as well as mitigate cost increases through long-term agreements, supplier engagement, and expanding the supply base. PGE is monitoring the fluid situation around tariffs and trade policies and continues to evaluate any potential impact to its operations and the need to implement applicable mitigation strategies.

Customers and Demand—The following tables present total energy deliveries, in thousands of Megawatt hours (MWh), and the average number of retail customers by customer type for the periods indicated:

Total retail energy deliveries for the six months ended June 30, 2025 increased 4.7% compared with the six months ended June 30, 2024, driven by an increase in industrial deliveries. The first six months of 2025 contained one fewer delivery day due to leap year in 2024.

Residential weather-adjusted deliveries saw average usage per customer 1.6% lower during the first six months of 2025 compared with 2024, while the average number of residential customers was 1.5% greater. PGE has seen the number of rooftop solar installations increase in its service territory over the past few years, and continued funding of energy efficiency programs, both of which weigh on average usage per customer.

51

The industrial class continues to show growth in energy deliveries, up 16.5% in the six months ended June 30, 2025 compared to the same period in 2024, reflecting strength primarily in the digital services sector.

The following table indicates the number of heating and cooling degree-days for the three and six months ended June 30, 2025 and 2024, along with the current 15-year averages based on weather data provided by the National Weather Service, as measured at Portland International Airport:

During the three months ended June 30, 2025 compared to the same three months of 2024, weather had a negative impact on Total Retail deliveries as the Company’s service territory saw fewer heating and cooling degree-days than in 2024. While temperatures were above average during the second quarters of both 2025 and 2024, the number of heating degree-days recorded in the second quarter of 2025 were 23% below average compared to 10% below in the same period of 2024.

The Company’s cost-of-service opt-out program caps participation by customers in the fixed three-year and minimum five-year opt-out programs, which account for the majority of energy delivered to Direct Access customers who purchase their energy from ESSs. Had the cap limit been fully subscribed and utilized, 12% of PGE’s total retail energy deliveries for the first six months of 2025 would have been to these customers.

PGE offers service to customers under an OPUC created New Large Load Direct Access program for unplanned, large, new loads and large load growth at existing customer sites. With the adoption of the New Large Load Direct Access program, which is capped at 119 MWa, as much as 17% of the Company’s retail energy deliveries could have been supplied by ESSs to Direct Access customers.

Actual deliveries to Direct Access customers of energy supplied by ESSs represented 11% and 10% of PGE’s total retail energy deliveries for the first six months of 2025 and 2024, respectively. The OPUC, under docket UM 2024, has undertaken an investigation of long-term Direct Access with program caps being one of the issues under consideration. This regulatory proceeding is expected to conclude in early 2026.

Power Operations—PGE utilizes a combination of its own generating resources and wholesale market transactions to meet the energy needs of its retail customers. The Company participates in wholesale markets by purchasing and selling electricity, natural gas, and environmental credits in an effort to meet the needs of, and obtain reasonably-priced power for, its retail customers. PGE continuously makes economic dispatch decisions based on numerous factors, such as plant availability, customer demand, river flows, wind conditions, and current wholesale prices. As a result, the amount of power generated and purchased in the wholesale market to meet the Company’s retail load requirement can vary from period to period and impacts NVPC and income from operations.

The following table provides information regarding the performance of the Company’s generating resources for the six months ended June 30, 2025 and 2024:

52

	Plant availability (1)				Actual energy provided compared to projected levels (2)				Actual energy provided as a percentage of total system load
	2025		2024		2025		2024		2025		2024
Generation:
Thermal:
Natural gas	84	%	77	%	104	%	91	%	37	%	32	%
Coal (3)	71		65		99		86		6		5
Wind (4)	90		91		98		102		10		11
Hydro	97		94		101		93		5		5

(1)Plant availability represents the percentage of the period plants were available for operations, which is impacted by planned maintenance and forced, or unplanned, outages.

(2)Projected levels of energy are included as part of PGE’s AUT. Such projections establish the power cost component of retail prices for the following calendar year. Any shortfall is generally replaced with power from higher cost sources, while any excess generally displaces power from higher cost sources.

(3)Plant availability reflects Colstrip, which PGE does not operate.

(4)Plant availability includes Wheatridge Renewable Energy Facility and Clearwater, which PGE does not operate.

Energy received from PGE-owned and jointly-owned thermal plants during the six months ended June 30, 2025 compared to 2024 increased 14%. This increase was primarily driven by fewer outages in 2025 as compared to 2024. Energy expected to be received from thermal resources is projected annually in the AUT based on forecast market prices, variable costs to run the plant, and the constraints of the plant. PGE’s thermal generating plants require varying levels of annual maintenance, which is generally performed during the second quarter of the year.

Total energy received from hydroelectric generation sources, both PGE-owned generation and purchased, increased 9% during the six months ended June 30, 2025 compared to 2024 primarily due to more favorable hydro conditions in the current period. Energy purchased from mid-Columbia and other regional hydroelectric projects increased 10% while energy generated by the Company-owned facilities increased 4% during the six months ended June 30, 2025. Energy expected to be received from hydroelectric resources is projected annually in the AUT based on a modified hydro study, which utilizes 10 years of historical stream flow data. See “Purchased power and fuel” in the Results of Operations section in this Item 2, for further detail on regional hydro results.

Energy received from PGE-owned and under contract wind resources decreased 9% during the six months ended June 30, 2025 compared to 2024. Energy expected to be received from wind generating resources is projected annually in the AUT based on historical generation. Wind generation forecasts are developed using a 5-year rolling average of historical wind levels or forecast studies when historical data is not available.

Under the PCAM, the Company may share with customers a portion of cost variances associated with NVPC. Customer prices can be adjusted annually to absorb a portion of the difference between the forecasted NVPC included in customer prices (baseline NVPC) and actual NVPC for the year, if such differences exceed a prescribed “deadband” limit, which ranges from $15 million below to $30 million above baseline NVPC. To the extent actual NVPC, subject to certain adjustments, is outside the deadband range, the PCAM provides for 90% of the excess variance to be collected from, or refunded to, customers. Pursuant to a regulated earnings test, a refund will occur only to the extent that it results in PGE’s actual regulated return on equity (ROE) for the given year being no less than 1% above the Company’s latest authorized ROE, while a collection will occur only to the extent that it results in PGE’s actual regulated ROE for that year being no greater than 1% below the Company’s authorized ROE. The following is a summary of the results of the PCAM as calculated for regulatory purposes for the six months ended June 30, 2025 and 2024, respectively:

53

•For the six months ended June 30, 2025, actual NVPC was $19 million below baseline NVPC. Based on forecast data, NVPC for the year ending December 31, 2025 is currently estimated to be below the baseline and outside the established deadband range. Pursuant to the PCAM and related earnings test, because PGE’s preliminary regulatory ROE is estimated to be below 10.34%, there is no estimated refund to customers expected under the PCAM for 2025.

•For the six months ended June 30, 2024, actual NVPC was $52 million below baseline NVPC. For the year ended December 31, 2024, actual NVPC was $78 million below baseline NVPC, which was outside the established deadband range. Pursuant to the PCAM and related earnings test, because PGE’s preliminary regulatory ROE was below 10.5%, there was no estimated refund to customers under the PCAM for 2024. A final determination regarding the 2024 PCAM results will be made by the OPUC through a public filing and review in 2025.

As approved by the OPUC in PGE’s 2024 GRC, the Reliability Contingency Event (RCE) mechanism allows PGE to pursue recovery of 80% of costs for RCEs above amounts forecasted in the Company’s AUT, with the remaining 20% flowing through operating expenses and subject to the existing PCAM. For more on the RCE, see “Regulatory Assets and Liabilities” in Note 3, Balance Sheet Components in the Notes to Condensed Consolidated Financial Statements in Item 1.—“Financial Statements.”

Operating and Maintenance

Business transformation and optimization expenses—PGE has incurred incremental costs, which include strategic advisory and workforce realignment expenses, focused on a multi-year cost management initiative to realize long-term benefits. Additionally, PGE has incurred incremental accounting, legal, and consulting costs related to its intent to submit a regulatory application for approval of a holding company reorganization. For more on the corporate structure see “Corporate Structure” in the Regulatory Matters section of this Overview.

For more information on the impact of these costs on quarterly results, see “Generation, transmission and distribution” and “Administrative and other” in the Results of Operations section of this Overview. The Company expects to incur business transformation and optimization expenses related to these initiatives throughout 2025 and 2026.

* Includes an allowance for borrowed funds used during construction of $3 million and $4 million for the three months ended June 30, 2025 and 2024, respectively, and $7 million and $8 million for the six months ended June 30, 2025 and 2024.

Net income for the three months ended June 30, 2025 decreased $10 million, or 14%, compared to the same period of 2024. Retail revenues increased primarily due to price changes as authorized by the OPUC. The increase in Purchased power and fuel reflects higher average variable power costs per MWh. Generation, transmission and distribution expenses were up primarily due to vegetation management, inspection, wildfire mitigation, and distribution maintenance expenses. While total Administrative and General expense remained flat compared to 2024, a total of $15 million business transformation and optimization expenses was recorded in 2025 of which $14 million is reflected in Administration and General Expense with the balance being in Generation, transmission and distribution expense. Increases in Depreciation and amortization expense, driven by higher depreciable asset balances, and Interest expense, net, due to higher long-term debt balances, were largely anticipated and somewhat offset in net income by increased revenues. Income tax expense was up due to lower PTC benefits.

55

Net income for the six months ended June 30, 2025 decreased $19 million, or 10%, compared to the same period of 2024. Retail revenues increased primarily due to price changes to cover anticipated higher NVPC and general cost increases, as authorized by the OPUC. Wholesale revenues have decreased, driven by a decline in the average price of wholesale deliveries. The reduction in Purchased power and fuel reflects reduced cost of purchased power, partially offset by the reduced costs in 2024 due to the deferral of costs under the RCE mechanism that did not recur. Generation, transmission and distribution expenses were up primarily due to vegetation management, inspection, wildfire mitigation, and distribution maintenance expenses. While total Administrative and General expense remained flat compared to 2024, a total of $15 million business transformation and optimization expenses was recorded in 2025 of which $14 million was in Administration and General Expense, with the balance being in Generation, transmission and distribution expense. Increases in Depreciation and amortization expense, driven by higher depreciable asset balances, and Interest expense, net, due to higher long-term debt balances, were largely anticipated and somewhat offset in net income by increased revenues. Income tax expense was up due to lower PTC benefits.

Total revenues consist of the following for the periods presented (dollars in millions):

Change in Total retail revenues	$	58	$	125

Wholesale revenues result from sales of electricity and environmental credits to utilities and power marketers made in the Company’s efforts to meet the needs of, and obtain reasonably priced power for, its retail customers, manage risk, and administer its long-term wholesale contracts. Such sales can vary significantly from year to year as a result of economic conditions, power and fuel prices, hydro and wind availability, and customer demand.

Wholesale revenues for the three months ended June 30, 2025 decreased $11 million, or 11%, from the three months ended June 30, 2024, as a combination of reduced environmental credit sales and a lower average wholesale sales price more than offset the 16% increase in sales volumes.

For the six months ended June 30, 2025, Wholesale revenues decreased $87 million, or 32%, from the six months ended June 30, 2024 as the Company experienced a $68 million reduction in revenues due to a decline in average sales prices resulting from market volatility around specific regional weather events in January 2024 and milder overall weather in 2025. In addition, the sale of environmental credits produced $28 million less revenue in 2025 than during the same period of 2024. Partially offsetting the declines was a 3% increase in Wholesale sales volumes, which added $9 million to revenues period over period.

Other operating revenues for the three months ended June 30, 2025 were up $2 million from the comparable period in 2024. In the six months ended June 30, 2025, Other operating revenues were up $10 million compared to the same period of 2024, primarily the result of an increase from imbalance transactions with ESS providers, which is offset in Purchased power and fuel expense.

Purchased power and fuel expense includes the cost of power purchased and fuel used to generate electricity to meet PGE’s retail load requirements, as well as the cost of settled electric and natural gas financial contracts.

57

The following items contributed to the change in Purchased power and fuel for the three and six months ended June 30, 2025 compared to the same periods in 2024 (dollars in millions):

	Three Months Ended		Six Months Ended
June 30, 2024	$	275	$	680

Total system load (MWhs in thousands):
June 30, 2024	6,774		14,384
June 30, 2025	7,095		14,638

For the three months ended June 30, 2025, the $20 million increase related to the change in average variable power cost per MWh was driven by an 18% increase in the average cost of purchased power and a 12% decrease in the average cost for the Company’s own generation. The $1 million increase related to total system load was comprised of a 7% decrease of energy obtained from purchased power, offset by an 18% increase in the Company’s own generation.

For the six months ended June 30, 2025, the $66 million decrease related to the change in average variable power cost per MWh was driven by an 11% decrease in the average cost of purchased power and a 5% decrease in the average cost for the Company’s own generation. The $18 million decrease related to total system load was comprised of a 7% decrease of energy obtained from purchased power, offset by a 9% increase in the Company’s own generation.

Change in NVPC	$	30	$	69

For further information regarding NVPC in relation to the PCAM, see “Purchased power and fuel expense” and “Revenues” within this “Results of Operations” for more details.

For the three months ended June 30, 2025 and 2024, actual NVPC was $12 million and $31 million below baseline NVPC, respectively. For the six months ended June 30, 2025 and 2024, actual NVPC was $19 million and $52 million below baseline NVPC, respectively.

Based on forecast data, NVPC for the year ending December 31, 2025 is currently estimated to be below the baseline and outside the deadband. Pursuant to the PCAM and related earnings test, because PGE’s preliminary regulatory ROE is estimated to be below 10.34%, there is no estimated refund to customers expected under the PCAM for 2025.

In the table above, for the three and six months ended June 30, 2025, respectively, $4 million and $8 million of the decrease in customer related costs is due to regulatory programs that have been offset through customer pricing or specific regulatory mechanisms.

Depreciation and amortization expense increased $17 million and $36 million in the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024. The increases were primarily due to higher utility plant balances.

Taxes other than income taxes increased $5 million and $4 million in the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024. The increases were driven by higher property taxes and higher franchise fees, partially offset by lower payroll taxes.

Interest expense, net increased $5 million and $10 million in the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024, primarily due to higher long-term debt balances.

61

Other income, net decreased $2 million and $3 million for the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024. The decreases were primarily driven by lower pension and Other Post Employment Benefits non-service costs.

Income tax expense increased $5 million and $14 million in the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024, primarily driven by lower PTC benefits resulting from the expiration of the 10-year PTC generation window at Tucannon near the end of 2024.

Critical Accounting Policies and Estimates

There have been no material changes to the Company’s critical accounting policies and estimates as previously disclosed in Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 14, 2025.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

PGE’s access to short-term debt markets, including revolving credit from banks, helps provide necessary liquidity to support the Company’s current operating activities, including the purchase of power and fuel. Long-term capital requirements are driven largely by capital expenditures for distribution, transmission, and generation facilities to support both new and existing customers, repairs from major storm damage, information technology systems, and debt refinancing activities. PGE’s liquidity and capital requirements can also be significantly affected by other working capital needs, including margin deposit requirements related to wholesale market activities, which can vary depending upon the Company’s forward positions and the corresponding price curves.

Cash Flows from Operating Activities—Cash flows from operating activities are generally determined by the amount and timing of cash received from customers and payments made to vendors, as well as the nature and amount of non-cash items, including depreciation and amortization, deferred income taxes, and pension and other postretirement benefit costs included in net income during a given period. The following items contributed to the net change in cash flows from operations for the six months ended June 30, 2025 compared with the six months ended June 30, 2024 (in millions):

	Increase/ (Decrease)
Net income	$	(19)
Accounts receivable and Unbilled revenue	36
Margin deposits activity	48
Accounts payable	(1)
Regulatory deferral activity	109
Depreciation and amortization	36
Deferred income taxes	(2)
Alternative revenue programs	(19)
Other miscellaneous changes	15
Net change in cash flow from operations	$	203

PGE estimates that non-cash charges for depreciation and amortization in 2025 will range from $550 million to $575 million. Combined with other sources, total cash expected to be provided by operations is estimated to range from $900 million to $1 billion.

Cash Flows from Investing Activities—Net cash used in investing activities for the six months ended June 30, 2025 decreased $30 million when compared with the six months ended June 30, 2024. Cash flows used in investing activities consist primarily of capital expenditures related to BESS projects and other new construction and improvements to PGE’s distribution, transmission, and generation facilities, which decreased $27 million.

Excluding AFUDC, the Company plans to make capital expenditures of $1.2 billion in 2025, which it expects to fund with cash to be generated from operations during 2025, as discussed above, the issuance of short- and long-term debt, and issuances of shares pursuant to the at-the-market offering program. For additional information, see “Debt and Equity Financings” in this Liquidity and Capital Resources section of Item 2.

Cash Flows from Financing Activities—During the six months ended June 30, 2025, net cash provided by financing activities was primarily the result of the funding of $310 million in First Mortgage Bonds (FMBs). This was partially offset by payment of $109 million of dividends and $102 million of long-term debt.

(2) Amounts are estimates as of the date of this report and may be affected by economic conditions, including but not limited to, impacts of inflation, changes to the cost of materials and labor, and financing costs.

Debt and Equity Financings

PGE’s ability to secure sufficient short- and long-term capital at a reasonable cost is determined by its financial performance and outlook, credit ratings, capital expenditure requirements, alternatives available to investors, market conditions, and other factors, such as the volatility in the capital markets in response to inflationary pressures and interest rate increases by the federal reserve. Management believes that the availability of its revolving credit facility, the expected ability to issue short- and long-term debt and equity securities, and cash expected to be generated from operations provide sufficient cash flow and liquidity to meet the Company’s anticipated capital and operating requirements for the foreseeable future.

For 2025, PGE expects to fund estimated capital requirements with cash from operations, which is expected to range from $900 million to $1 billion, and issuances of long-term debt of up to $450 million. PGE plans to fund any shortfall through the combination of issuance of common stock and the issuance of short-term debt or commercial paper, as needed. The actual timing and amount of any such issuances of debt, equity, and commercial paper will be dependent upon the timing and amount of capital expenditures and debt payments.

Short-term Debt. Pursuant to an order issued by the FERC in January 2024, PGE has authorization to issue short-term debt up to a total of $900 million through February 6, 2026. The following table shows available liquidity as of June 30, 2025 (in millions):

	As of June 30, 2025
	Capacity		Outstanding		Available
Revolving credit facility (1)	$	750	$	—	$	750
Letters of credit (2)	320		146		174
Total credit	$	1,070	$	146	$	924
Cash and cash equivalents					56
Total liquidity					$	980

(1)Scheduled to expire September 2029.

(2)PGE has four letter of credit facilities under which the Company can request letters of credit for an original term not to exceed one year.

On September 10, 2024, PGE entered into an amendment of its existing revolving credit facility. As of June 30, 2025, PGE had a $750 million unsecured revolving credit facility scheduled to expire in September 2029. The Company has the ability to expand the revolving credit facility to $850 million, if needed, subject to the requirements of the agreement. The facility allows for unlimited extension requests, provided that lenders with a pro-rata share of more than 50% of the facility approve the extension request. The revolving credit facility supplements operating cash flows and provides a primary source of liquidity. Pursuant to the terms of the agreement, the revolving credit facility may be used as backup for commercial paper borrowings, to permit the issuance of standby letters of credit, and to provide cash for general corporate purposes. 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 remaining term of the applicable credit facility. As of June 30, 2025, PGE 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, limited to the unused amount of credit under the revolving credit facility. As of June 30, 2025, PGE had no commercial paper outstanding. The aggregate unused available credit capacity under the revolving credit facility was $750 million. The Company has elected to limit its borrowings under the revolving credit facility in order to allow coverage for the potential need to repay any commercial paper that may be outstanding at the time.

Long-term Debt. As of June 30, 2025, PGE’s total long-term debt outstanding, net of $15 million of unamortized debt expense, was $4,731 million.

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.

Equity. In July 2024, PGE entered into an equity distribution agreement under which it could sell up to $400 million of its common stock through at-the-market offering programs. In the fourth quarter of 2024 the Company entered into forward sale agreements for 1,420,049 shares. In December 2024, the Company issued 1,066,549 shares pursuant to the forward sale agreements and received net proceeds of $50 million. The Company entered into forward sale agreements for 1,996,890 shares and 1,707 shares in the first quarter and the second quarter of 2025, respectively. The Company could have physically settled the remaining amount by delivering 2,352,097 shares in exchange for cash of $104 million as of June 30, 2025. Any proceeds from the issuances of common stock will be used for general corporate purposes and investments in renewables and non-emitting dispatchable capacity.

For additional information on the at-the-market offering programs, see Note 7, Shareholders’ Equity, in the Notes to Condensed Consolidated Financial Statements in Item 1.—“Financial Statements.”

Capital Structure. PGE’s financial objectives include maintaining a common equity ratio (common equity to total consolidated capitalization, including current debt maturities and excluding lease obligations) of approximately 50% over time. Achievement of this objective helps the Company maintain investment grade credit ratings and provides

65

access to long-term capital at favorable interest rates. The Company’s common equity ratio was 44.9% and 45.6% as of June 30, 2025 and December 31, 2024, respectively.

Credit Ratings and Debt Covenants

PGE’s secured and unsecured debt is rated investment grade by Moody’s Investors Service (Moody’s) and S&P Global Ratings (S&P), with current credit ratings and outlook as follows:

	Moody’s	S&P
Issuer credit rating	A3	BBB+
Senior secured debt	A1	A
Commercial paper	P-2	A-2
Outlook	Negative	Stable

In the event Moody’s or S&P reduce their credit rating on PGE’s unsecured debt below investment grade, the Company could be subject to requests by certain of its wholesale, commodity, and transmission counterparties to post additional performance assurance collateral in connection with its price risk management activities. The performance assurance collateral can be in the form of cash deposits or letters of credit, depending on the terms of the underlying agreements, are based on the contract terms and commodity prices, and can vary from period to period. Cash deposits that PGE provides as collateral are classified as Margin deposits in PGE’s condensed consolidated balance sheets, while any letters of credit issued are not reflected on the condensed consolidated balance sheets.

As of June 30, 2025, PGE had posted $118 million of collateral with these counterparties, consisting of $40 million in cash and $78 million in letters of credit. Based on the Company’s energy portfolio, estimates of energy market prices, and the level of collateral outstanding as of June 30, 2025, the amount of additional collateral that could be requested upon a single agency downgrade to below investment grade is $45 million, and decreases to $9 million by December 31, 2025 and to an immaterial amount by December 31, 2026. The amount of additional collateral that could be requested upon a dual agency downgrade to below investment grade is $127 million and decreases to $62 million by December 31, 2025 and to $52 million by December 31, 2026.

PGE’s financing arrangements do not contain ratings triggers that would result in the acceleration of required interest and principal payments in the event of a ratings downgrade. However, the cost of borrowing and issuing letters of credit under the credit facilities would increase.

The indenture securing PGE’s outstanding FMBs constitutes a direct first mortgage lien on substantially all regulated utility property, other than expressly excepted property. Interest is payable semi-annually on FMBs. The issuance of FMBs requires that PGE meet earnings coverage and security provisions set forth in the Indenture of Mortgage and Deed of Trust (Indenture) securing the bonds. PGE estimates that on June 30, 2025, under the most restrictive issuance test in the Indenture, the Company could have issued up to $574 million of additional FMBs. Any issuances of FMBs would be subject to market conditions and amounts could be further limited by regulatory authorizations or by covenants and tests contained in other financing agreements. PGE also has the ability to release property from the lien of the Indenture under certain circumstances, including bond credits, deposits of cash, or certain sales, exchanges, or other dispositions of property.

PGE’s revolving credit facility contains customary covenants and credit provisions, including a requirement that limits consolidated indebtedness, as defined in the credit agreements, to 65.0% of total capitalization (debt-to-total capital ratio). As of June 30, 2025, the Company’s debt-to-total capital ratio, as calculated under the credit agreement, was 55.1%.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

PGE is exposed to various forms of market risk, consisting primarily of fluctuations in commodity prices, foreign currency exchange rates, and interest rates, as well as credit risk. Any variations in the Company’s market risk or credit risk may affect its future financial position, results of operations, or cash flows. There have been no material changes to market risks, or credit risk, affecting the Company from those set forth in Part II, Item 7A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 14, 2025.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

PGE’s management, under the supervision and with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures as required by Exchange Act Rule 13a-15(b) as of the end of the period covered by this report. Based on that evaluation, PGE’s Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2025, these disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in PGE’s internal control over financial reporting that occurred during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

See Note 8, Contingencies in the Notes to Condensed Consolidated Financial Statements in Item 1.—“Financial Statements,” for information regarding legal proceedings.

Item 1A. Risk Factors.

Other than the items noted below, there have been no material changes to PGE’s risk factors set forth in Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 14, 2025.

Trade tariffs and related market volatility and supply chain disruptions could increase PGE’s operating costs, impair PGE’s ability to complete capital projects, and impede access to capital markets.

Recently imposed trade tariffs could negatively impact PGE’s financial condition, results of operations, and cash flows. While the impact of these trade tariffs is difficult to predict at this time, economic volatility, supply chain disruption, or cost increases triggered by these trade tariffs could negatively affect PGE’s ability to execute its strategic plan. Adverse capital and credit market conditions caused by the new trade tariffs could negatively affect the Company’s access to capital, cost of capital, and ability to complete capital projects.

67

The perceived risk of wildfire exposure could adversely affect PGE’s access to capital, hinder the Company’s ability to execute its strategic plan, and increase costs.

The lack of legislation limiting wildfire-related liability or providing a wildfire relief fund may impact PGE’s credit rating, which could hamper the Company’s ability to attract capital and invest in the infrastructure required to meet emissions targets and customer reliability needs. PGE may face barriers to securing cost-efficient contracts if there is a perceived risk of utility financial losses related to wildfire. Business partners may be forced to increase prices to recognize the unresolved financial exposure that PGE presents as a counterparty.
