“PSEG delivered a solid operating and financial performance

to begin the year,” said Ralph LaRossa, PSEG’s chair, president and CEO. “Our teams across PSE&G and PSEG Power successfully responded to multiple extreme weather events during the first quarter. These included the worst winter

storm to hit our service territory in the past 30 years and several days of single digit temperatures that prompted our highest gas send-out since 2019. PSEG’s investments in critical energy

infrastructure and our dedicated workforce that worked tirelessly to restore service in frigid conditions proved to be the key factors in our ability to deliver

best-in-class storm response and reliability.”

“PSEG has

worked with the Governor’s Office and the New Jersey Board of Public Utilities to keep electric rates flat in 2026, in keeping with Governor Sherrill’s Executive Orders 1 & 2 addressing utility costs and generation supply. PSE&G

rates will also benefit from the update to reflect the latest Basic Generation Service auction results effective on June 1. On February 1st, we also kept our residential natural gas rate flat for

the remainder of the 2025-2026 winter heating season, providing our customers with the lowest gas bills in New Jersey and in the region. PSEG Nuclear also had a strong first quarter, supplying 8 TWh of reliable, carbon-free baseload energy to New

Jersey and the grid.”

LaRossa added, “We continue to execute on our long-term strategy to grow PSEG’s non-GAAP Operating Earnings by a compound annual rate of 6% to 8% through 2030 – without the need to issue new equity or sell assets – which remains a core differentiator from our peers.”

PSE&G’s results for the first quarter reflect ongoing investments in Energy Efficiency, Gas System Modernization and

Transmission; the seasonality of gas demand during the winter months; and the continued, gradual increase in the number of electric and gas customers. These results were partially offset by higher operation and maintenance costs as well as higher

depreciation and interest expense related to incremental investments.

PSEG Power & Other results for the quarter reflect higher realized prices

and lower operation and maintenance costs, partly offset by lower generating volume and the absence of zero emission certificates.

About PSEG

Public

Service Enterprise Group (PSEG) (NYSE: PEG) is a predominantly regulated infrastructure company operating New Jersey’s largest transmission and distribution utility, serving approximately 2.4 million electric and 1.9 million natural

gas customers. PSEG also owns an independent fleet of 3,758 MW of carbon-free, baseload nuclear power generating units in NJ and PA. PSEG aims to power a future where people use energy more efficiently, and it’s safer and delivered more

reliably than ever. PSEG is a member of the S&P 500 Index and has been named

2

to the Dow Jones Best-in-Class North America Index for 18 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. Operating Earnings is a non-GAAP financial measure that differs from Net Income. 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-GAAP Operating 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.

Forward-Looking Statements

Certain of the matters discussed in this report about our and our subsidiaries’ future performance, including, without limitation, future revenues,

earnings, strategies, prospects, consequences, and all other statements that are not purely historical constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such

forward-looking statements are subject to risks and uncertainties, which could cause actual results to differ materially from those anticipated. Such statements are based on management’s beliefs as well as assumptions made by and information

currently available to management. When used herein, the words “anticipate,” “intend,” “estimate,” “believe,” “expect,” “plan,” “should,” “hypothetical,”

“potential,” “forecast,” “project,” variations of such words and similar expressions are intended to identify forward-looking statements. Factors that may cause actual results to differ are often presented with

the forward-looking statements themselves. Other factors that could cause actual results to differ materially from those contemplated in any forward-looking statements made by us herein are discussed in filings we make with the United States

Securities and Exchange Commission (SEC), including our Annual Report on Form 10-K and subsequent reports on Form 10-Q and Form

8-K. These factors include, but are not limited to:

any inability to successfully develop, obtain regulatory approval for, or construct transmission and

distribution, and our nuclear generation projects;

significant resource adequacy challenges that present affordability and reliability concerns and that could cause

policymakers to implement responsive measures that could have a material, adverse impact on our business, strategy, growth rates, cash flows, results of operations, and financial condition and increase regulatory uncertainty for utility investment

initiatives and programs;

the physical, financial and transition risks related to climate change, including risks relating to potentially

increased legislative and regulatory burdens, changing customer preferences and lawsuits;

any equipment failures, gas explosions, accidents, critical operating technology or business system failures,

natural disasters, severe weather events, acts of war, terrorism or other acts of violence, sabotage, physical attacks or security breaches, cyberattacks or other incidents that may impact our ability to provide safe and reliable service to our

customers;

any inability to recover the carrying amount of our long-lived assets;

disruptions or cost increases in our supply chain, including labor shortages;

any inability to maintain sufficient liquidity or access sufficient capital on commercially reasonable terms;

the impact of cybersecurity attacks or intrusions or other disruptions to our information technology, operational

or other systems;

failure to attract and retain a qualified workforce;

increases in the costs of equipment, materials, fuel, services and labor;

the impact of our covenants in our debt instruments and credit agreements on our business;

3

adverse performance of our defined benefit plan trust funds and Nuclear Decommissioning Trust Fund and increases

in funding requirements;

any inability to enter into or extend certain significant contracts;

development, adoption and use of Artificial Intelligence by us and our third-party vendors;

fluctuations in, or third-party default risk in wholesale power and natural gas markets, including the potential

impacts on the economic viability of our generation units;

the ability to obtain adequate nuclear fuel supply;

changes in technology related to energy generation, distribution and consumption and changes in customer usage

patterns;

third-party credit risk relating to our sale of nuclear generation output and purchase of nuclear fuel;

any inability to meet our commitments under forward sale obligations and Regional Transmission Organization

rules;

risks associated with generation activities at, and operation of, the Peach Bottom plants, which are similar to

those to which nuclear generation plants that we operate are subject;

the impact of changes in state and federal legislation and regulations on our business, including

PSE&G’s ability to recover costs and earn returns on authorized investments;

PSE&G’s proposed investment projects or programs may not be fully approved by regulators and its

capital investment may be lower than planned;

our ability to receive sufficient financial support for our New Jersey nuclear plants from the markets, and/or

production tax credits;

adverse changes in and non-compliance with energy industry laws,

policies, regulations and standards, including market structures and transmission planning and transmission returns;

risks associated with our ownership and operation of nuclear facilities, including increased nuclear fuel storage

costs, regulatory risks, such as compliance with the Atomic Energy Act and trade control, environmental and other regulations, as well as operational, financial, environmental and health and safety risks;

changes in or violation of federal, state and local environmental laws and regulations and enforcement;

delays in receipt of, or an inability to receive, necessary licenses and permits and siting approvals; and

changes in tax laws and regulations.

All of the forward-looking statements made in this report are qualified by these cautionary statements and we cannot assure you that the results or

developments anticipated by management will be realized or even if realized, will have the expected consequences to, or effects on, us or our business, prospects, financial condition, results of operations or cash flows. Readers are cautioned not to

place undue reliance on these forward-looking statements in making any investment decision. Forward-looking statements made in this report apply only as of the date of this report. While we may elect to update forward-looking statements from time to

time, we specifically disclaim any obligation to do so, even in light of new information or future events, unless otherwise required by applicable securities laws.

The forward-looking statements contained in this report are intended to qualify for the safe harbor provisions of Section 27A of the Securities Act of

1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.
