All 2025 emissions data is preliminary and subject to change as internal review procedures are performed. Certain emissions information is subject to review and approval by ODEQ and Environmental Protection Agency. 1. Percentages above represent 2025 resource mix from PGE's total system load, inclusive of wholesale and retail volumes. The percentage of 2025 retail loads as defined by Oregon Department of Environment Quality (ODEQ), which excludes wholesale sales, served by non-emitting resources is 40%. This resource mix does not include battery storage. Refer to the appendix for additional information. 2. Rooftop solar and community solar are based on gross generation, which is total energy generated before any on-site customer usage. 3. Hydro amounts include purchases from Bonneville Power Administration and Tacoma Power, which may have an immaterial amount of emissions associated with them, per ODEQ rules. 4. Unspecified is purchased power for which a specific generating resource is not defined and could be any of the generation types (e.g., wind, hydro, gas).

This presentation contains certain non-GAAP measures, such as adjusted earnings, adjusted EPS and adjusted earnings guidance. These non-GAAP financial measures exclude significant items that are generally not related to our ongoing business activities, are infrequent in nature, or both. PGE believes that excluding the effects of these items provides an alternative measure of the Company's comparative earnings per share and enables investors to evaluate the Company's operating financial performance trends, exclusive of items that are not normally associated with ongoing operations. Management utilizes non-GAAP measures to assess the Company's current and forecasted performance, and for communications with shareholders, analysts and investors. Non-GAAP financial measures are supplementary information that should be considered in addition to, but not as a substitute for, the information prepared in accordance with GAAP. Items in the periods presented, which PGE believes impact the comparability of comparative earnings and do not represent ongoing operating financial performance, include the following: 2022: Non-cash Wildfire and COVID deferral reversal charge associated with the year ended 2020, resulting from the OPUC's 2022 GRC Final Order earnings test 2023: Boardman revenue requirement settlement charge associated with the year ended 2020, resulting from the OPUC's 2022 GRC Final Order 2024: Non-deferrable Reliability Contingency Event (RCE) costs resulting from the January 2024 winter storm 2025: Business transformation and optimization expenses, including strategic advisory, workforce realignment and corporate structure update costs 2026: Business transformation and optimization expenses, including strategic advisory, workforce realignment and corporate structure update costs; acquisition costs, including legal, financing and strategic advisory costs; Non-cash charge related to final orders on the January 2024 storm and damage and 2024 Reliability Contingency Event regulatory deferrals Due to the forward-looking nature of PGE's non-GAAP adjusted earnings guidance, and the inherently unpredictable nature of items and events which could lead to the recognition of non-GAAP adjustments (such as, but not limited to, regulatory disallowances or extreme weather events), management is unable to estimate the occurrence or value of specific items requiring adjustment for future periods, which could potentially impact the Company's GAAP earnings. Therefore, management cannot provide a reconciliation of non-GAAP adjusted earnings per share guidance to the most comparable GAAP financial measure without unreasonable effort. For the same reasons, management is unable to address the probable significance of unavailable information. PGE's reconciliation of non-GAAP earnings for the years ended December 31, 2022, December 31, 2023, December 31, 2024 and December 31, 2025 are on the following slide. Non-GAAP financial measures
