® 25 Key Areas Potential Business Impact Current Status CapEx and OpEx ◦ Focus on essential work ◦ No net earnings impact given ratemaking structure Collection Delays and Uncollectible Revenues ◦ Delay in customer collections as a result of shelter-in-place and moratorium on service disconnections ◦ No anticipated earnings impact due to COVID-19 Pandemic Protections Memorandum Account (CPPMA) Electric and Gas Demand ◦ Revenues decoupled from energy usage and trued-up annually ◦ In 2021, decreased load/reduced billings for 2020 will be collected through the annual electric and gas true-up processes. PG&E is no longer estimating a load impact from COVID-19 after December 31, 2020. Liquidity ◦ Net reduction in near-term monthly cash inflows with sufficient liquidity to fund ongoing operations ◦ ~$3.2B of total liquidity at June 30, 2021: ▪ $233 million of Utility cash ▪ $74 million of PG&E Corporation cash ▪ $2.9 billion available under credit facilities (includes Utility and Corp credit facilities) Appendix 7: COVID-19 Impacts Overall, PG&E’s key wildfire mitigation and safety work execution has not been impacted by COVID-19. California's constructive regulatory framework minimizes potential earnings impacts from reduced load and higher uncollectibles. Changes from prior quarter noted in blue

High end of the range includes capital spend above authorized and reflects the spending forecast from the 2023 GRC application. 2. CapEx forecast includes ~$3.2B of fire risk mitigation capital expenditures included in the Utility’s approved wildfire mitigation plans on which PG&E Corporation and the Utility will not earn an equity return. The Utility has spent approximately $1.7 billion cumulatively towards this total including approximately $200 million and $300 million during the three and six months ended June 30, 2021, respectively. 3. The Utility will enter into a lease, with an option to purchase in 2023, the Lakeside Building in Oakland, California, in accordance with its application to sell its San Francisco General Office headquarters complex and as requested in the 2023 GRC.

® 31 Appendix 9: Presentation Footnotes Slide 14: 1. Includes amounts not yet filed for recovery less reserves and equity return that cannot be recognized for accounting purposes until approved by the CPUC. Slide 20: 1. Participation in the AB 1054 Wildfire Fund is subject to PG&E making the required annual contributions to the Fund and maintaining reasonable insurance coverage. 2. The useful life of the Wildfire Fund is estimated based on various assumptions, including the number and severity of catastrophic fires within the participating electric utilities’ service territories during the term of the Wildfire Fund, historical fire-loss data, the estimated cost of wildfires caused by other electric utilities, the amount at which wildfire claims will be settled, the likely adjudication of the CPUC in cases of electric utility-caused wildfires, the level of future insurance coverage held by the electric utilities, and the future transmission and distribution equity rate base growth of other electric utilities. Significant changes in any of these estimates could materially impact the amortization period. Slide 21: 1. Eligible claims are those exceeding the greater of $1 billion or the insurance coverage required to be in place pursuant to Cal. Pub. Util. Code § 3293. PG&E carried $900M of wildfire insurance coverage at June 30, 2021. PG&E can seek cost recovery of claims below the $1B fund threshold but above insurance coverage levels through CPUC prudency review. 2. For utility caused fires deemed imprudent, the Fund is re-infused up to the liability cap, currently estimated at ~$2.9B (calculated based on 20% of PG&E Equity T&D rate base for 2021). Cap applies to aggregate reimbursements to the fund over a rolling three calendar year period. Cap does not apply if Utility is found to have conscious or willful disregard of the rights and safety of others. Slide 22: 1. The rate case timelines outlined above reflect expected filing and decision time frames; actual timing may differ. 2. Any potential trigger to the Annual Adjustment to the Cost of Capital Mechanism in 2021 could impact 2022 earnings. 3. The approved TO19 settlement will be 98.5% of TO18 rate case outcome. 4. Rate Neutral Securitization bonds may be issued in up to tree series on or prior to December 31, 2022.

® 39 Definitions of 2021 Operational Performance Metrics from Exhibit C Customer Welfare – prioritizing public and employee safety Public and employee safety are measured in five areas: Electric Operations, Gas Operations, Generation, Reliability, and Workforce Safety. The safety of the Utility’s electric operations is represented by: • Wildfire Risk Reduction – The metric measures the count of Fire Ignitions that result in fires equal to or greater than 100 acres in PG&E’s High Fire Threat District (HFTD) and reportable to the California Public Utilities Commission (CPUC) per Decision 14-02-015. A reportable fire incident per Decision 14-02-015 is a fire event that meets the following criteria: 1) ignition is associated with PG&E power lines (both transmission and distribution), 2) something other than PG&E facilities burned, and 3) the resulting fire travelled more than one meter from the ignition point. • Wire-Down Events Due to Equipment Failure Rate – Wire-Down Events Due to Equipment Failure are instances where a normally energized electric primary distribution or transmission conductor experiences a component or asset failure (e.g., pole or splice) that results in a conductor falling from its intended position and coming to rest on the ground or on a foreign object (e.g., a vehicle or tree). The safety of the Utility’s gas operations is represented by: • Large Overpressure Events Rate – Measures the number of large overpressure events year-over-year and reduction in the number of large overpressure events. • Total Dig-Ins Reduction – Tracks the number of gas dig-ins per 1,000 Underground Service Alert tickets received for gas. The dig-in component tracks all dig-ins to PG&E gas subsurface installations. A gas dig-in refers to damage which occurs during excavation activities (impact or exposure) and results in a repair or replacement of an underground gas facility. The safety of the Utility’s generation operations is represented by: • Safe Dam Operating Capacity (SDOC) – Measures operating capability of mechanical equipment used as the main control to reduce enterprise risk of large uncontrolled water release. • Diablo Canyon Power Plant (DCPP) Reliability and Safety Indicator – Based on 11 performance indicators for nuclear power generation developed by the nuclear industry and applied to all U.S. nuclear power plants (measured for DCPP Unit 1 and Unit 2). The safety of the Utility’s Reliability is represented by: • Gas Customer Emergency Response – Measures the average response time in minutes for immediate response orders for the performance period. The response time by PG&E is measured from the time PG&E is notified to the time a Gas Service Representative (or a qualified first responder) arrives onsite to the emergency location (including business hours and after hours).

® 40 Definitions of 2021 Operational Performance Metrics from Exhibit C Customer Welfare – prioritizing public and employee safety (continued) • Electric 911 Emergency Response – Measures the percentage of time that PG&E personnel respond (are on site) within 60 minutes after receiving a 911 call, with onsite defined as arriving at the premises where the 911 agency personnel are waiting. • Customers Experiencing Multiple Interruptions (CEMI) – Measures the number of customers that experience multiple sustained outages (both unplanned and planned). • Average Speed of Answer for Emergencies – Measures the average speed of answer in seconds for emergency calls handled in Contact Center Operations. The safety of the Utility’s Workforce Safety is represented by: • Days Away, Restricted, & Transferred (DART) Rate – Measures OSHA-recordable injuries that result in lost time or restricted duty per 200,000 hours worked, or for approximately every 100 employees. • Serious Injuries – Actual – A Serious Injury or Fatality (SIF) Actual is defined as any injury or illness resulting from work at/for PG&E that results in: ◦ A fatality – work-related fatal injury or illness; ◦ A life threatening injury or illness, that if not addressed could lead to a fatality or work-related injury or illness that required immediate life- preserving rescue action, and if not applied immediately would likely have resulted in the death of that person; or ◦ A life altering injury or illness, one that results in the loss or permanent impairment of a limb, organ or body function – work-related injury or illness that resulted in a permanent and significant loss of a major body part or organ function. For this metric, only SIF Actuals not resulting in a fatality will be counted. • % of SIF Investigations Completed within 30 days – Measures SIF Actual and SIF Potential investigations completed by 30 calendar days following classification of incident as a SIF. • % of SIF Corrective Actions Completed on Time – Measures the completion of corrective actions related to SIF Actual or SIF Potential cause evaluations. Financial Non-GAAP Core Earnings per Share (shown in dollars per share) represents the financial performance from ongoing core operations. “Non-GAAP core earnings” is a non-GAAP financial measure and is calculated as income available for common shareholders less non-core items. “Non-core items” include items that management does not consider representative of ongoing earnings and affect comparability of financial results between periods, consisting of items listed in Exhibit A.

PG&E Corporation’s management generally does not use Adjusted EBITDA in managing its business. Adjusted EBITDA is calculated as PG&E Corporation’s net income plus income tax provision (or less income tax benefit); less other income, net; plus interest expense; less interest income; plus reorganization items, net; plus depreciation, amortization, and decommissioning; plus additional 2021 and 2020 adjustments for Wildfire Fund expense, 2019-2020 wildfire-related costs, net of insurance, prior period net regulatory recoveries, and investigation remedies. Adjusted EBITDA is not a substitute or alternative for GAAP measures, such as net income, and may not be comparable to similarly titled measures used by other companies. See above for a reconciliation of GAAP net income to non-GAAP Adjusted EBITDA. Second Quarter, 2021 vs. 2020 Exhibit G: GAAP Net Income to Non-GAAP Adjusted EBITDA Reconciliation PG&E Corporation

® 47 Exhibit H: Use of Non-GAAP Financial Measures PG&E Corporation and Pacific Gas and Electric Company: Use of Non-GAAP Financial Measures PG&E Corporation discloses historical financial results and provides guidance based on “non-GAAP core earnings” and “non-GAAP core EPS” in order to provide a measure that allows investors to compare the underlying financial performance of the business from one period to another, exclusive of non-core items. “Non-GAAP core earnings” is a non-GAAP financial measure and is calculated as income available for common shareholders less non-core items. “Non-core items” include items that management does not consider representative of ongoing earnings and affect comparability of financial results between periods, consisting of the items listed in Exhibit A. “Non-GAAP core EPS,” also referred to as “non-GAAP core earnings per share,” is a non-GAAP financial measure and is calculated as non-GAAP core earnings divided by common shares outstanding (diluted). PG&E Corporation and the Utility use non-GAAP core earnings and non-GAAP core EPS to understand and compare operating results across reporting periods for various purposes including internal budgeting and forecasting, short- and long-term operating planning, and employee incentive compensation. PG&E Corporation and the Utility believe that non-GAAP core earnings and non-GAAP core EPS provide additional insight into the underlying trends of the business, allowing for a better comparison against historical results and expectations for future performance. With respect to our projection of Non-GAAP Core EPS for the years 2022-2025, we are not providing a reconciliation to the corresponding GAAP measures because we are unable to predict with reasonable certainty the reconciling items that may affect GAAP net income without unreasonable effort. The reconciling items are primarily due to the future impact of wildfire-related costs, timing of regulatory recoveries, special tax items, and investigation remedies. These reconciling items are uncertain, depend on various factors and could significantly impact, either individually or in the aggregate, the GAAP measures. Non-GAAP core earnings and non-GAAP core EPS are not substitutes or alternatives for GAAP measures such as consolidated income available for common shareholders and may not be comparable to similarly titled measures used by other companies.
