® 33 (6) “Rate neutral securitization and Fire Victim Trust tax benefit" includes the impact of post-emergence securitization and tax benefits related to Fire Victim Trust. Impacts of the post-emergence rate neutral securitization include the establishment of a securitization regulatory asset and an offsetting regulatory liability associated with revenue credits funded by up-front shareholder contributions and Net Operation Loss monetization. Fire Victim Trust tax benefits include tax benefits recognized upon the sale of PG&E shares by the Fire Victim Trust, which PG&E has elected to treat as a grantor trust. The low and high cases reflect the assumption that the CPUC's final decision, issued on May 11, 2021, authorizing the securitization of $7.5 billion of wildfire-related claims, is final and non-appealable and bonds are issued in 2022. The low case includes tax benefits for the 100 million shares sold by the Fire Victim Trust as of April 14, 2022 and the high case reflects an assumption that the Fire Victim Trust sells all 477 million shares in 2022.

PG&E Corporation’s management generally does not use Adjusted EBITDA in managing i ts business. Adjusted EBITDA is calculated as PG&E Corporation’s net income plus income tax provision (or less income tax benefit); less o ther income, net; plus interest expense; less interest income; plus depreciation, amortization, and decommissioning; plus Wildfire Fund expense; plus wildfire-related costs, net of insurance; plus prior period net regulatory impact; and plus 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. Exhibit E: GAAP Net Income to Non-GAAP Adjusted EBITDA Reconciliation PG&E Corporation First Quarter, 2022 vs. 2021

® 37 Exhibit F: 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 (taken on a basic basis in the event of a GAAP loss and a diluted basis in the event of a GAAP gain). 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 2023-2026, 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.
