Forward-Looking Statements

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 returns (losses) associated with the Nuclear Decommissioning Trust (NDT), Mark-to-Market (MTM) accounting and material one-time items. 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 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. 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. Due to the forward-looking nature of non-GAAP Operating Earnings 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. GAAP Disclaimer From time to time, PSEG and PSE&G release important information via postings on their corporate Investor Relations website at https://investor.pseg.com. Investors and other interested parties are encouraged to visit the Investor Relations website to review new postings. You can sign up for automatic email alerts regarding new postings at the bottom of the webpage at https://investor.pseg.com or by navigating to the Email Alerts webpage here.

Inflation Reduction Act of 2022 supports de-carbonization efforts and establishes a nuclear power production tax credit, expands incentives and promotes carbon-free generation IRA 2022 Provision PSEG PSE&G New Federal Energy Tax Credit Provisions Enacts a nuclear power PTC for existing generation PSEG qualifies for up to $15/MWh subject to adjustment based on gross receipts Initial PTC and cap are subject to annual inflation adjustments Seeking U.S. Treasury clarification on gross receipts definition (on which the phase out is based) Provides energy efficiency and electric vehicle rebates for residents and businesses Equalizes the PTC rate for offshore wind with the 30% ITC rate Improves tax credit monetization with transferability and expands carryback period from one to three years Corporate Minimum Tax We are continuing to analyze the impact of the corporate minimum tax on our businesses including additional future guidance that U.S. Treasury is expected to issue. We anticipate that the sale of our fossil portfolio could mitigate near-term applicability of the minimum tax. The impact to state income tax is unknown at this point.

State Regulatory and Policy Initiatives Update State Regulatory Proceedings PSE&G submitted a regulatory filing with the BPU in early September requesting an order to modify PSE&G’s pension accounting for ratemaking purposes Requested effective date of January 1, 2023, which would reduce future variability of pension impacts on our financial results, and provide a partial offset to potential pension headwinds in 2023 and beyond BPU completed its review of offshore wind transmission (State Agreement Approach) and awarded several onshore solutions, with indications for an additional solicitation to consider future offshore wind needs Investment Priorities Aligned with NJ’s Clean Energy Agenda On track to complete second phase of our GSMP reducing methane emissions by replacing ~875 miles of cast iron and unprotected steel main Filed $320 million, nine month CEF-EE extension with BPU to align timing of PSE&G energy efficiency programs with other utilities in the state; expect to file longer term extension in 2023 BPU expected to address the balance of ~$0.2 billion of CEF filings (MHDV and CEF-ES) in conjunction with stakeholder proceedings on each of the initiatives Board staff expected to issue the second MHDV Straw Proposal by year end; BPU release of the MHDV Minimum Filing Requirements will follow a subsequent comment period Virtual stakeholder meetings scheduled to discuss BPU Straw Proposal focused on incentivizing stand-alone energy storage devices PSEG’s 25% interest in Ørsted's 1,100 MW Ocean Wind 1 (2025E fully in service) project expands carbon-free fleet with contracted, renewable generation supporting New Jersey’s goal of 100% clean energy by 2050. PSEG is reviewing its options regarding the status of its equity investment in the project

Pension is measured annually, at year-end, in determining pension impact for the following year PSEG does not “smooth” the year-end asset value, instead, we will apply our EROA assumption (7.2% for 2022) to the Fair Value of Plan Assets at year-end in determining pension impact for the following year PSEG’s long-standing methodology is deemed to be preferable by accounting standards PSEG also calculates the difference between the Expected and Actual Rate of Return on Plan Assets, which contributes to determining Net Actuarial Gain/Loss If the current year amount, in conjunction with existing Net Actuarial Gain/Loss, exceeds 10% of the greater of our Benefit Obligation or the Fair Value of Plan Assets (corridor), we amortize that over ~16 years As of 12/31/2021, PSEG had funded ~95% of its pension Benefit Obligation; Based on IRS minimum funding requirements, no cash contributions are anticipated for the next few years ($ Millions) 2021 2020 Discount Rate 2.94% 2.61% Expected Rate of Return on Plan Assets (EROA) 7.7% 7.7% Fair Value of Plan Assets at Beginning of Year $6,368 $5,929 Actual Return on Plan Assets $886 $761 Fair Value of Plan Assets at Year-End $6,906 $6,368 Benefit Obligation at Year-End $7,240 $7,507 Funded Status at Year-End 95% 85% Net Actuarial Loss at Year-End $1,643 $2,354 Source: PSEG 2021 10-K, pages 59, 117-120 Actively pursuing initiatives to reduce variability and mitigate potential near-term headwinds, including a recent filing at the BPU

Includes the financial impact from positions with forward delivery months. Nine months ended September 30, 2022 includes the results for fossil generation sold in February 2022. Income tax effect calculated at the statutory rate except for qualified NDT related activity, which records an additional 20% trust tax on income (loss) from qualified NDT Funds, and the additional investment tax credit (ITC) 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 three months and nine months ended September 30, 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 year to date results to reconcile the two EPS calculations.
