Portland General Electric Announces Second Quarter 2023 Results
•Advanced strategic priorities, including making constructive progress in the 2024 GRC and procuring the 75 MW Evergreen battery energy storage system
•Second quarter results reflect robust retail deliveries growth, challenging power market conditions, prioritization of system reliability and resiliency, and execution of long-term capital investment plans
•Reaffirming 2023 adjusted earnings guidance of $2.60 to $2.75 per diluted share
PORTLAND, Ore. -- Portland General Electric Company (NYSE: POR) today reported net income based on generally accepted accounting principles (GAAP) of $39 million, or $0.39 per diluted share, for the second quarter of 2023. After adjusting for the impact of the pre-tax $6.5 million Boardman revenue requirement settlement charge, second quarter 2023 non-GAAP net income was $44 million, or $0.44 per diluted share. This compares with GAAP net income of $64 million, or $0.72 per diluted share, for the second quarter of 2022.
“We made solid progress this quarter as we navigated power cost volatility, settled remaining regulatory deferrals and advanced critical work to reduce risk,” said Maria Pope, PGE President and CEO. “Our long-term growth plan is increasingly well-established, underpinned by investments to meet growing customer needs and facilitate the clean energy transition.”
Second Quarter 2023 Compared to Second Quarter 2022
Total revenues increased, driven by higher demand from digital and semiconductor customers. Purchased power and fuel expense increased primarily due to less favorable power market conditions driven by substantial changes in regional hydro conditions. Operating and administrative expenses increased due to higher grid maintenance and resiliency costs and higher generation maintenance costs driven by significantly higher thermal operating rates. Other income increased due to gains on non-qualified benefit plan assets from improved market performance.
Company Updates
2024 General Rate Case
On February 15, 2023, PGE filed with the OPUC a General Rate Case based on a 2024 test year (2024 GRC) requesting an increase that, when including Colstrip-related adjustments through a supplemental tariff, results in an overall average increase of approximately 14% in customer prices for 2024.
Settlement discussions in the 2024 GRC have been productive and PGE and parties have arrived at several agreements in principle that would settle items related to a portion of PGE’s transmission and distribution capital request, a capital structure of 50% debt and 50% equity, several core business issues, such as the treatment of the
1

transfer and sale of PTCs, and certain NVPC matters. Parties are preparing the respective term sheets and testimony related to the partial stipulations, which the Company expects to file with the OPUC in the third quarter. Remaining unresolved issues include cost of capital, adjustments to the PCAM, and recovery of certain other capital projects.
Regulatory review, including approval of any related stipulations, of the 2024 GRC (OPUC Docket UE 416) will continue throughout 2023, with a final order expected to be issued by the OPUC in December 2023, for new customer prices effective January 1, 2024.
2021 All-Source Request for Proposal Conclusion
On May 30, 2023, PGE reached an agreement to procure the Evergreen battery energy storage system (BESS), a new 75 megawatt facility to be located in Hillsboro, Oregon.
The Evergreen BESS, combined with the previously announced Clearwater Wind, Seaside BESS and Troutdale BESS, represent the final projects to be procured from the 2021 All-Source Request For Proposal (RFP). Additional resources necessary to meet the Company's remaining 2030 capacity need are anticipated to be procured through future acquisition processes, including, but not limited to, the 2023 All-Source RFP and future RFPs.
Resource Planning and 2023 All-Source RFP Updates
In March, PGE filed with the OPUC its first combined Integrated Resource Plan (IRP) and Clean Energy Plan (CEP), which articulates the Company’s strategy to meet the 2030, 2035, and 2040 emission reduction targets, as mandated by Oregon law, through an equitable transition to a decarbonized grid. In July, PGE filed an Addendum to the 2023 CEP and IRP with the OPUC on July 7, 2023. This addendum includes a portfolio analysis refresh. As part of the CEP and IRP refresh, PGE estimates a total resource need of approximately 3,500 to 4,500 MW of renewable energy and non-emitting capacity in order to meet the Company’s 2030 emissions reduction target. Through the 2021 All-Source RFP, PGE procured 311 MW of wind and 475 MW of capacity, leaving a remaining need to procure of approximately 2,700 to 3,700 MW.
In alignment with local and regional transmissions plans, the IRP Action Plan and CEP, PGE is evaluating options to upgrade existing transmission resources and assessing expansions of current transmission networks. Resources being pursued are intended to alleviate congestion, improve regional adequacy and reliability, enable decarbonization goals, and address growing customer demand.
Quarterly Dividend
As previously announced, on July 21, 2023, the board of directors of Portland General Electric Company approved a quarterly common stock dividend of $0.475 per share. The quarterly dividend is payable on or before October 16, 2023 to shareholders of record at the close of business on September 25, 2023.
2023 Earnings Guidance
PGE is reaffirming its estimate for full-year 2023 adjusted earnings guidance of $2.60 to $2.75 per diluted share based on the following assumptions:
•An increase in energy deliveries between 2.5% and 3%, weather adjusted;
•Normal temperatures in its utility service territory;
•Hydro conditions for the year that reflect current estimates;
•Wind generation based on five years of historical levels or forecast studies when historical data is not available;
•Normal thermal plant operations;
•Operating and maintenance expense between $695 million and $715 million which includes approximately $45 million of storm, wildfire and related deferral and other expenses that are offset in revenue and other income statement lines;
•Depreciation and amortization expense between $445 million and $465 million;
2

•Effective tax rate of 15% to 20%;
•Cash from operations of $525 to $575 million;
•Capital expenditures of $1,475 million; and
•Average construction work in progress balance of $570 million.
Second Quarter 2023 Earnings Call and Webcast — July 28, 2023
PGE will host a conference call with financial analysts and investors on Friday, July 28, 2023, at 11 a.m. ET. The conference call will be webcast live on the PGE website at investors.portlandgeneral.com.

The attached unaudited condensed consolidated statements of income and comprehensive income, balance sheets and statements of cash flows, as well as the supplemental operating statistics, are an integral part of this earnings release.
Non-GAAP Financial Measures
This press release 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 a meaningful representation of the Company’s comparative earnings per share and enables investors to evaluate the Company’s ongoing operating financial performance. 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:
•Boardman revenue requirement settlement charge associated with the year ended 2020, resulting from the OPUC’s 2022 GRC Final Order.
PGE's reconciliation of non-GAAP earnings for the three months ended June 30, 2023 is below.
