Readers are cautioned not to place undue reliance on these forward-looking statements in making any investment decision. Forward-looking statements made in this presentation apply only as of the date of this presentation.

Forward-Looking Statements

PSEG presents Operating Earnings and Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) in addition to its Net Income reported in accordance with accounting principles generally accepted in the United States (GAAP). Operating Earnings and Adjusted EBITDA are non-GAAP financial measures that differ from Net Income. Non-GAAP Operating Earnings exclude the impact of returns (losses) associated with the Nuclear Decommissioning Trust (NDT), Mark-to-Market (MTM) accounting and material one-time items. Non-GAAP Adjusted EBITDA excludes the same items as our non-GAAP Operating Earnings measure as well as income tax expense, interest expense and depreciation and amortization. The last two slides in this presentation (Slides A and B) include a list of items excluded from Net Income/(Loss) to reconcile to non-GAAP Operating Earnings and non-GAAP Adjusted EBITDA with a reference to those slides included on each of the slides where the non-GAAP information appears. Management uses non-GAAP Operating Earnings in its internal analysis, and in communications with investors and analysts, as a consistent measure for comparing PSEG’s financial performance to previous financial results. Management believes non-GAAP Adjusted EBITDA is useful to investors and other users of our financial statements in evaluating operating performance because it provides them with an additional tool to compare business performance across companies and across periods. Management also believes that non-GAAP Adjusted EBITDA is widely used by investors to measure operating performance without regard to items such as income tax expense, interest expense and depreciation and amortization, which can vary substantially from company to company depending upon, among other things, the book value of assets, capital structure and whether assets were constructed or acquired. Non-GAAP Adjusted EBITDA also allows investors and other users to assess the underlying financial performance of our fleet before management’s decision to deploy capital. The presentation of non-GAAP Operating Earnings and non-GAAP Adjusted EBITDA is intended to complement, and should not be considered an alternative to, the presentation of Net Income, which is an indicator of financial performance determined in accordance with GAAP. In addition, non-GAAP Operating Earnings and non-GAAP Adjusted EBITDA as presented in this release may not be comparable to similarly titled measures used by other companies. Due to the forward looking nature of non-GAAP Operating Earnings and non-GAAP Adjusted EBITDA guidance, PSEG is unable to reconcile these non-GAAP financial measures to the most directly comparable GAAP financial measure. Management is unable to project certain reconciling items, in particular MTM and NDT gains (losses), for future periods due to market volatility.

Key Provisions of the Zero Emission Certificate Program Zero Emission Certificate On April 18, the BPU awarded ZECs to PSEG Nuclear’s three NJ nuclear plants: Hope Creek and Salem 1 and Salem 2. The BPU completed a process outlined by legislation passed in May 2018 that provided contracts to awarded nuclear plants equal to no more than 40% of NJ’s retail electric deliveries. The BPU’s award was based on an assessment of financial need in addition to the nuclear plants’ impact on the state’s air quality, fuel diversity, and environmental attributes. Term Hope Creek and Salem 1 and Salem 2 receive ZECs for a “stub period” beginning April 18 through the end of current energy year (May 31, 2019) plus an additional three years starting June 1, 2019 to May 31, 2022. 13 months prior to the conclusion of the first 3-year period (April 30, 2021), an eligible nuclear power plant can apply to receive ZECs for a subsequent three-year period. Impact Will preserve an important carbon-free source of power for New Jersey, save New Jersey electricity customers hundreds of millions of dollars in what would have been higher energy costs, save thousands of jobs, preserve fuel diversity and prevent a significant increase in environmentally damaging air emissions.
