“PSEG delivered a solid operating and financial performance to begin the year. Our

T2service territory experienced multiple cold spells in January and February with temperatures remaining below 20°F for several days in a row, prompting the highest winter peak load for both gas and electric in the last six years. During these

challenging conditions, our electric and gas operations maintained high levels of reliability and efficient customer response times,” said Ralph LaRossa, PSEG’s chair, president and CEO.

“T3Our regulated capital investment plan for 2025 remains focused on infrastructure replacement and modernization to ensure safe and reliable service, and

to meet growing customer demand. PSE&G also began rolling out the second phase of its Clean Energy Future - Energy Efficiency II program, which helps customers save energy, lower their bills and reduce carbon emissions while supporting job

training and economic growth in New Jersey.”

“T4PSE&G experienced another quarterly increase in large load inquiries for new service

connections. This pipeline totaled over 6,400 MW of capacity requested as of March 31, and our engineers have been responding to these inquiries on a timely basis – still

1

averaging about four months. Our speed to response is supportive of the state objective to spur economic development. To the extent these large load prospects convert into new utility customers

in the future, fixed costs are spread over a larger user base, which helps to lower existing customer bills.”

“At PSEG Nuclear, T5we generated

approximately 8.4 terawatt hours of energy during the first quarter, supplying the grid with 24x7, carbon-free power and achieving a capacity factor of 99.9%.”

LaRossa added, “PSEG’s focus on increasing the predictability of our results continues to benefit both customers and the company, aided by our

Conservation Incentive Program, and deferral mechanisms from the recently concluded rate case. T6We also constantly manage our cost structure to keep bills as low as possible. Preserving PSEG’s financial flexibility helps us to accomplish our

financial and strategic goals, including executing on PSE&G’s regulated capital investment plan, which is on track and on budget.”

“PSEG continues to pursue opportunities to grow our existing 5% to 7% compound annual growth outlook for non-GAAPOperating Earnings over the 2025 to 2029 period, including the potential to contract our nuclear output under long-term agreements.”

“PSEG also

T7declared a first-quarter common stock dividend of $0.63 per share, representing an indicative annual rate of $2.52 per share, a 5% increase for 2025,” said LaRossa.

PSE&G’s results for the first quarter reflect new electric and gas base distribution rates in effect for a full

quarter following the October 15, 2024 implementation date. This increase in revenue reflected over $3 billion of investments made in the electric and gas systems over the past several years. The improvement in results also reflects the

seasonality of higher gas revenue collection during the winter months, which was partly offset by higher operation and maintenance costs as well as higher depreciation and interest expense from recent capital investments.

PSEG Power & Other results for the quarter reflect the positive impact of our consistent and

reliable nuclear generation performance coupled with higher realized prices, primarily driven by the cold weather experienced in January and February.

gas customers. PSEG also owns an independent fleet of 3,758 MW of carbon-free, baseload nuclear power generating units in NJ and PA. Guided by its Powering Progress vision, PSEG aims to power a future where people use less energy, and it’s

cleaner, safer and delivered more reliably than ever. PSEG is a member of the S&P 500 Index and has been named to the Dow Jones Sustainability North America Index for 17 consecutive years. PSEG’s businesses include Public Service

Electric and Gas Co. (PSE&G), PSEG Power and PSEG Long Island (https://corporate.pseg.com).

Non-GAAP Financial Measures

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. Non-GAAP Operating Earnings exclude the impact of gains (losses) associated with the Nuclear

Decommissioning Trust (NDT), Mark-to-Market (MTM) accounting and other material infrequent items.

See Attachments 7 and 8 for a complete list of items excluded from Net Income in the determination of non-GAAPOperating Earnings. The presentation of non-GAAP Operating Earnings 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 as presented in this report 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 this non-GAAP financial measure to the most directly comparable GAAP financial measure because comparable GAAP measures are not reasonably accessible or reliable due to the inherent difficulty in forecasting and

quantifying measures that would be required for such reconciliation. Namely, we are not able to reliably project without unreasonable effort MTM and NDT gains (losses), for future periods due to market volatility. These items are uncertain, depend

on various factors, and may have a material impact on our future GAAP results.
