StatementsThis presentation contains statements regarding management?s expectations and objectives for future periods as well as forecasts and estimates regarding 2018 IIC guidance, Tax Cuts and Jobs Act expected impact, 2017-2019 capital expenditures, 2017-2019 weighted average ratebase, and general earnings sensitivities. It also includes 2018 assumptions regarding capital expenditures, authorized rate base, authorized cost of capital, and certain other factors. These statements and other statements that are not purely historical constitute forward-looking statements that are necessarily subject to various risks and uncertainties. Actual results may differ materially from those described in forward-looking statements. PG&E Corporation and the Utility are not able to predict all the factors that may affect future results. Factors that could cause actual results to differ materially include, but are not limited to:the impact of the Northern California wildfires, including whether Pacific Gas and Electric Company (Utility) will be able to recover costs for service restoration and repair to the Utility?s facilities through its Catastrophic Event Memorandum Account (CEMA); the timing and outcome of the wildfire investigations; whether the Utility may have liability associated with these fires and, if liable for one or more fires, whether the Utility would be able to recover all or part of such costs through insurance or through regulatory mechanisms, to the extent insurance is not available or exhausted; and potential liabilities in connection with fines or penalties that could be imposed on the Utility if the California Public Utilities Commission (CPUC) or any other lawenforcement agency brought an enforcement action and determined that the Utility failed to comply with applicable laws and regulations; the timing and outcome of the Butte fire litigation; the timing and outcome of any proceeding to recover from customers restoration and repair costs and costs in excess of insurance; the effect, if any, that the CPUC?s Safety and Enforcement Division?s (SED) $8.3 million citations issued in connection with the Butte fire may have on the Butte fire litigation; and whether additional investigations and proceedings in connection wi h the Butte fire will be opened and any additional fines or penalties imposed on the Utility; whether the CPUC approves the Utility?s application to establish a Wildfire Expense Memorandum Account (WEMA) to track wildfire expenses and to preserve the opportunity for the Utility to request recovery of wildfire costs in excess of insurance at a future date, and the outcome of any potential request to recover such costs; the impact of the Tax Cuts and Jobs Act of 2017, and the timing and outcome of CPUC decision(s) related to the Utility?s March 30, 2018 submissions in connection with the impact of the Tax Cuts and Jobs Act of 2017 on the Utility?s rate cases, and its implementation plan; the timing and outcomes of the 2019 GT&S rate case, TO18 and TO19 rate cases, 2018 CEMA, and other ratemaking and regulatory proceedings; the cost of the Utility’s community wildfire safety program, and the timing and outcome of any proceeding to recover such costs through rates; the timing and outcomes of phase two of the ex parte order instituting investigation (OII) and of the safety culture OII; the Utility?s ability to efficiently manage capital expenditures and its operating and maintenance expenses within the authorized levels of spending and timely recover its costs through rates, and the extent to which the Utility incurs unrecoverable costs that are higher than the forecasts of such costs; whether the Utility can continue to obtain insurance and whether insurance coverage is adequate for future losses or claims; the outcome of the probation and the monitorship, the timing and outcomes of the debarment proceeding, the SED?s unresolved enforcement matters relating to the Utility?s compliance with natural gas-related laws and regulations, and other investigations that have been or may be commenced, and the ultimate amount of fines, penalties, and remedial and other costs that the Utility may incur as a result; the ability of PG&E Corporation and the Utility to access capital markets and other sources of financing in a timely manner on acceptable terms; further changes in credit ratings which could, among other things, result in higher borrowing costs and fewer financing options, especially if PG&E Corporation or the Utility were to lose their investment grade credit ratings; and the other factors disclosed in PG&E Corporation and the Utility?s joint annual report on Form 10-K for the year ended December 31, 2017, their joint quarterly report on Form 10-Q for the quarter ended March 31, 2018, and other reports filed with the Securities and Exchange Commission (SEC), which are available on PG&E Corporation?s website at www.pgecorp.com and on the SEC website at www.sec.gov.To be UpdatedInformation regarding 2018 IICs, 2018 Assumptions, and 2018 Earnings Sensitivities was issued on May 3, 2018.

PG&E Corporation uses non-GAAP earnings from operations 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 believes that non-GAAP earnings from operations provide additional insight into the underlying trends of the business, allowing for a better comparison against historical results and expectations for future performance. Non-GAAP earnings from operations are not a substitute or alternative for GAAP measures such as consolidated income available for common shareholders and may not be comparable to similarly titled measures used by other companies.40
