PSEG | Investor Conference 2023

GAAP Disclaimer PSEG presents Operating Earnings in addition to its Net Income/(Loss) reported in accordance with accounting principles generally accepted in the United States (GAAP). Operating Earnings is a non-GAAP financial measure that differs from Net Income/(Loss). Non-GAAP Operating Earnings exclude the impact of gains (losses) associated with the Nuclear Decommissioning Trust (NDT), Mark-to-Market (MTM) accounting and material one-time items. The second from last slide in this presentation (Slide A) includes a list of items excluded from Net Income/(Loss) to reconcile to non-GAAP Operating Earnings. 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. The presentation of non-GAAP Operating Earnings is intended to complement, and should not be considered an alternative to, the presentation of Net Income/(Loss), which is an indicator of financial performance determined in accordance with GAAP. In addition, non-GAAP Operating Earnings as presented in this release may not be comparable to similarly titled measures used by other companies. PSEG also includes forward-looking estimates of non-GAAP Operating Earnings, non-GAAP Earnings Before Interest, Tax, Depreciation and Amortization (EBITDA) and non-GAAP Funds From Operations (FFO), including the non-GAAP ratio FFO/Debt, in this presentation. Non-GAAP EBITDA excludes the same items as our non-GAAP Operating Earnings measure, as well as income tax expense (except for production tax credits (PTCs)), interest expense and depreciation and amortization.  Non-GAAP FFO reflects cash from operations excluding working capital and adjusts for certain items including taxes on asset sales, cost of removal and energy efficiency investments. Non-GAAP Debt consists of long-term debt, short-term debt and other imputed debt primarily related to an unfunded pension obligation.  Non-GAAP EBITDA and non-GAAP FFO, as referenced in this presentation, may not be comparable to similarly titled measures used by other companies. Given the forward-looking nature of non-GAAP Operating Earnings, non-GAAP Adjusted EBITDA and non-GAAP FFO estimates and our inability to project certain reconciling items that would be excluded from the most directly comparable GAAP measures – such as MTM and NDT gains (losses), with respect to non-GAAP EBITDA; working capital (including accounts receivable/payable, cash collateral), adjustments to Net Income (including changes in regulatory assets/liabilities, deferred taxes) with respect to non-GAAP FFO and non-GAAP debt and imputed debt (including unfunded pension obligation) with respect to non-GAAP debt - due to the volatility, complexity and low visibility of these items, PSEG is unable to reconcile these non-GAAP financial measures to the most directly comparable GAAP financial measure. These items are uncertain, depend on various factors, and may have a material impact on our future GAAP results.

Reconciliation of Non-GAAP Operating Earnings  Effective January 1, 2018, unrealized gains (losses) on equity securities are recorded in Net Income (Loss) instead of Other Comprehensive Income (Loss). Includes the financial impact from positions with forward delivery months. Full year 2022 includes the results for fossil generation sold in February 2022. Full year 2021 amounts include a pre-tax loss of $298 million for the make-whole premium paid upon the early redemption of PSEG Power's debt and other non-cash debt extinguishment costs.  Income tax effect calculated at 28.11% statutory rate for 2018 through 2022 and 40.85% statutory rate for prior years, except for qualified NDT related activity, which records an additional 20% trust tax on income (loss) from qualified NDT Funds, the additional investment tax credit recapture related to the sale of PSEG Solar Source in 2021, and leveraged lease related activity, which is calculated at a combined leveraged lease effective tax rate. Approximately three million potentially dilutive shares were excluded from fully diluted average shares outstanding used to calculate the diluted GAAP loss per share for the year ended December 31, 2021 as their impact was antidilutive to GAAP results. For non-GAAP per share calculations, we used fully diluted average shares outstanding of 507 million, including the three million potentially dilutive shares as they were dilutive to non-GAAP results. As a result of the use of different denominators for non-GAAP Operating Earnings and GAAP Net Loss, a reconciling line item, “Share Differential,” has been added to the 2021 results to reconcile the two Earnings/(Loss) per share calculations.  Please see Slide 5 for an explanation of PSEG’s use of Operating Earnings as a non-GAAP financial measure and how it differs from Net Income/(Loss).
