| Revenues | Note 2. Revenues Nature of Goods and Services The following is a description of principal activities by which PSEG and its subsidiaries generate their revenues. PSE&G Revenues from Contracts with Customers Electric and Gas Distribution and Transmission Revenues—PSE&G sells gas and electricity to customers under default commodity supply tariffs. PSE&G’s regulated electric and gas default commodity supply and distribution services are separate tariffs which are satisfied as the product(s) and/or service(s) are delivered to the customer. The electric and gas commodity and delivery tariffs are recurring contracts in effect until modified through the regulatory approval process as appropriate. Revenue is recognized over time as the service is rendered to the customer. Included in PSE&G’s regulated revenues are unbilled electric and gas revenues which represent the estimated amount customers will be billed for services rendered from the most recent meter reading to the end of the respective accounting period. PSE&G’s transmission revenues are earned under a separate tariff using a FERC-approved annual formula rate mechanism. The performance obligation of transmission service is satisfied and revenue is recognized as it is provided to the customer. The formula rate mechanism provides for an annual filing of an estimated revenue requirement with rates effective January 1 of each year and a true-up to that estimate based on actual revenue requirements. The true-up mechanism is an alternative revenue which is outside the scope of revenue from contracts with customers. Other Revenues from Contracts with Customers Other revenues from contracts with customers, which are not a material source of PSE&G revenues, are generated primarily from appliance repair services and solar generation projects. The performance obligations under these contracts are satisfied and revenue is recognized as control of products is delivered or services are rendered. Revenues Unrelated to Contracts with Customers Other PSE&G revenues unrelated to contracts with customers are derived from alternative revenue mechanisms recorded pursuant to regulatory accounting guidance. These revenues, which include the Conservation Incentive Program (CIP), green energy program true-ups and transmission formula rate true-ups, are not a material source of PSE&G revenues. PSEG Power & Other Revenues from Contracts with Customers Electricity and Related Products—PSEG Power owns generation solely within PJM Interconnection, L.L.C. (PJM), which facilitates the dispatch of energy and energy-related products. PSEG Power primarily sells to the PJM Independent System Operator (ISO) energy and ancillary services which are separately transacted in the day-ahead or real-time energy markets. The energy and ancillary services performance obligations are typically satisfied over time as delivered and revenue is recognized accordingly. PSEG generally reports electricity sales and purchases conducted with PJM net on an hourly basis in either Operating Revenues or Energy Costs in its Condensed Consolidated Statements of Operations. The classification depends on the net hourly activity. PSEG Power enters into capacity sales and capacity purchases through PJM. The transactions are reported on a net basis dependent on PSEG Power’s monthly net sale or purchase position through PJM. The performance obligations with PJM are satisfied over time upon delivery of the capacity and revenue is recognized accordingly. In addition to capacity sold through PJM, PSEG Power sells capacity through bilateral contracts and the related revenue is reported on a gross basis and recognized over time upon delivery of the capacity. In May 2025, PSEG Power’s Salem 1, Salem 2 and Hope Creek nuclear plants zero emission certificate (ZEC) sales concluded. These nuclear plants received ZEC revenue from the electric distribution companies (EDCs) in New Jersey. PSEG Power recognized revenue when the units generated electricity, which was when the performance obligation was satisfied. These revenues have been considered variable consideration within the scope of revenue from contracts with customers and are included in PJM Sales in the following tables. ZEC revenue has been adjusted by the estimated production tax credit (PTCs) generated from these nuclear plants. ZEC revenue will be adjusted based upon the actual value of the PTCs generated by these nuclear plants and that adjustment could be material. In March 2026, the BPU issued a proposal instructing how nuclear plants should refund to the EDCs, and then how EDCs should refund to customers, the value of the ZECs generated in 2024 and purchased from the nuclear plants that were subsequently offset by PTC. Gas Contracts—PSEG Power sells wholesale natural gas, primarily through an index based full-requirements Basic Gas Supply Service (BGSS) contract with PSE&G to meet the gas supply requirements of PSE&G’s customers. The BGSS contract remains in effect unless terminated by either party with a two-year notice. Based upon the availability of natural gas, storage and pipeline capacity beyond PSE&G’s daily needs, PSEG Power also sells gas and pipeline capacity to other counterparties under bilateral contracts. The performance obligation is primarily the delivery of gas which is satisfied over time. Revenue is recognized as gas is delivered or pipeline capacity is released. PSEG LI Contract—PSEG LI has a contract with LIPA which generates revenues. PSEG LI’s subsidiary, Long Island Electric Utility Servco, LLC (Servco) records costs which are recovered from LIPA and records the recovery of those costs as revenues when Servco is a principal in the transaction. In September 2025, the LIPA board of trustees approved a five-year extension of the contract. See Amended OSA below for further information. Other Revenues from Contracts with Customers PSEG Power had contracted to provide energy management and fuel procurement services for LIPA. Revenue was recognized over time as services were rendered. This agreement expired in December 2025. Revenues Unrelated to Contracts with Customers PSEG Power’s revenues unrelated to contracts with customers include electric, gas and certain energy-related transactions accounted for in accordance with Derivatives and Hedging accounting guidance. See Note 10. Financial Risk Management Activities for further discussion. Energy Holdings generates lease revenues which are recorded pursuant to lease accounting guidance. Disaggregation of Revenues
(A) Includes revenues applicable to PSEG Power, PSEG LI and Energy Holdings. (B) Includes primarily revenues from appliance repair services and the sale of solar renewable energy credits (SRECs) at auction at PSE&G. PSEG Power & Other includes PSEG LI’s OSA with LIPA and PSEG Power’s energy management fee with LIPA. (C) Includes alternative revenues at PSE&G, including CIP, Green Program Recovery Charge (GPRC) and transmission over or under recoveries, which are authorized to be collected or refunded in the future periods, and derivative contracts and lease contracts at PSEG Power & Other. Contract Balances PSE&G PSE&G did not have any material contract balances (rights to consideration for services already provided or obligations to provide services in the future for consideration already received) as of March 31, 2026 and December 31, 2025. Substantially all of PSE&G’s accounts receivable and unbilled revenues result from contracts with customers that are priced at tariff rates. The allowance for credit losses represented approximately 12% of accounts receivable (including unbilled revenues) as of both March 31, 2026 and December 31, 2025. Accounts Receivable—Allowance for Credit Losses PSE&G’s accounts receivable, including unbilled revenues, is primarily comprised of utility customer receivables for the provision of electric and gas service and appliance services, and are reported on the balance sheet as gross outstanding amounts adjusted for an allowance for credit losses. The allowance for credit losses reflects PSE&G’s best estimate of losses on the account balances. The allowance is based on PSE&G’s projection of accounts receivable aging, historical experience, economic factors and other currently available evidence. PSE&G’s electric bad debt expense is recoverable through its Societal Benefits Clause (SBC) mechanism. The following provides a reconciliation of PSE&G’s allowance for credit losses for the three months ended March 31, 2026 and 2025:
PSEG Power & Other PSEG Power generally collects consideration upon satisfaction of performance obligations, and therefore, PSEG Power had no material contract balances as of March 31, 2026 and December 31, 2025. PSEG Power’s accounts receivable include amounts resulting from contracts with customers and other contracts which are out of scope of accounting guidance for revenues from contracts with customers. The majority of these accounts receivable are subject to master netting agreements. As a result, accounts receivable resulting from contracts with customers and receivables unrelated to contracts with customers are netted within Accounts Receivable and Accounts Payable on the Condensed Consolidated Balance Sheets. PSEG Power’s accounts receivable consist mainly of revenues from energy and ancillary services sold directly to ISOs and other counterparties. In the wholesale energy markets in which PSEG Power operates, payment for services rendered and products transferred are typically due within 30 days of delivery. As such, there is little credit risk associated with these receivables. PSEG Power did not record an allowance for credit losses for these receivables as of March 31, 2026 or December 31, 2025. PSEG Power monitors the status of its counterparties on an ongoing basis to assess whether there are any anticipated credit losses. PSEG LI did not have any material contract balances as of March 31, 2026 and December 31, 2025. Remaining Performance Obligations under Fixed Consideration Contracts PSEG primarily records revenues as allowed by the guidance, which states that if an entity has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date, the entity may recognize revenue in the amount to which the entity has a right to invoice. PSEG has future performance obligations under contracts with fixed consideration as follows: Capacity Revenues from the PJM Annual Base Residual and Incremental Auctions—The Base Residual Auction is generally conducted annually three years in advance of the operating period. However, changes to capacity market rules have resulted in auction suspensions and delays so that recent auctions have been run closer in time to their operating periods. In July 2024 the results of the 2025/2026 auction were released, in July 2025 the results of the 2026/2027 auction were released and in December 2025 the results of the 2027/2028 auction were released. PSEG Power expects to realize the following average capacity prices resulting from the base and incremental auctions, including unit specific bilateral contracts for previously cleared capacity obligations.
Amended OSA—PSEG LI has been operating LIPA’s electric T&D system in Long Island, New York since 2014 under a 12-year OSA with LIPA that expired on December 31, 2025, with annual fixed and variable components. The fixed fee for the provision of services thereunder in 2025 was approximately $45 million. In December 2025, PSEG LI entered into a five-year extension of the OSA ending on December 31, 2030. The fixed fee for the provision of services in 2026 and 2027 is approximately $43 million, escalating to approximately $47 million in 2028 and updated annually based on the change in the Consumer Price Index through the remainder of the contract. A competitor in the contract bidding process filed litigation against LIPA challenging the process.

| Revenues | Note 2. Revenues Nature of Goods and Services The following is a description of principal activities by which PSEG and its subsidiaries generate their revenues. PSE&G Revenues from Contracts with Customers Electric and Gas Distribution and Transmission Revenues—PSE&G sells gas and electricity to customers under default commodity supply tariffs. PSE&G’s regulated electric and gas default commodity supply and distribution services are separate tariffs which are satisfied as the product(s) and/or service(s) are delivered to the customer. The electric and gas commodity and delivery tariffs are recurring contracts in effect until modified through the regulatory approval process as appropriate. Revenue is recognized over time as the service is rendered to the customer. Included in PSE&G’s regulated revenues are unbilled electric and gas revenues which represent the estimated amount customers will be billed for services rendered from the most recent meter reading to the end of the respective accounting period. PSE&G’s transmission revenues are earned under a separate tariff using a FERC-approved annual formula rate mechanism. The performance obligation of transmission service is satisfied and revenue is recognized as it is provided to the customer. The formula rate mechanism provides for an annual filing of an estimated revenue requirement with rates effective January 1 of each year and a true-up to that estimate based on actual revenue requirements. The true-up mechanism is an alternative revenue which is outside the scope of revenue from contracts with customers. Other Revenues from Contracts with Customers Other revenues from contracts with customers, which are not a material source of PSE&G revenues, are generated primarily from appliance repair services and solar generation projects. The performance obligations under these contracts are satisfied and revenue is recognized as control of products is delivered or services are rendered. Revenues Unrelated to Contracts with Customers Other PSE&G revenues unrelated to contracts with customers are derived from alternative revenue mechanisms recorded pursuant to regulatory accounting guidance. These revenues, which include the Conservation Incentive Program (CIP), green energy program true-ups and transmission formula rate true-ups, are not a material source of PSE&G revenues. PSEG Power & Other Revenues from Contracts with Customers Electricity and Related Products—PSEG Power owns generation solely within PJM Interconnection, L.L.C. (PJM), which facilitates the dispatch of energy and energy-related products. PSEG Power primarily sells to the PJM Independent System Operator (ISO) energy and ancillary services which are separately transacted in the day-ahead or real-time energy markets. The energy and ancillary services performance obligations are typically satisfied over time as delivered and revenue is recognized accordingly. PSEG generally reports electricity sales and purchases conducted with PJM net on an hourly basis in either Operating Revenues or Energy Costs in its Condensed Consolidated Statements of Operations. The classification depends on the net hourly activity. PSEG Power enters into capacity sales and capacity purchases through PJM. The transactions are reported on a net basis dependent on PSEG Power’s monthly net sale or purchase position through PJM. The performance obligations with PJM are satisfied over time upon delivery of the capacity and revenue is recognized accordingly. In addition to capacity sold through PJM, PSEG Power sells capacity through bilateral contracts and the related revenue is reported on a gross basis and recognized over time upon delivery of the capacity. In May 2025, PSEG Power’s Salem 1, Salem 2 and Hope Creek nuclear plants zero emission certificate (ZEC) sales concluded. These nuclear plants received ZEC revenue from the electric distribution companies (EDCs) in New Jersey. PSEG Power recognized revenue when the units generated electricity, which was when the performance obligation was satisfied. These revenues have been considered variable consideration within the scope of revenue from contracts with customers and are included in PJM Sales in the following tables. ZEC revenue has been adjusted by the estimated production tax credit (PTCs) generated from these nuclear plants. ZEC revenue will be adjusted based upon the actual value of the PTCs generated by these nuclear plants and that adjustment could be material. In March 2026, the BPU issued a proposal instructing how nuclear plants should refund to the EDCs, and then how EDCs should refund to customers, the value of the ZECs generated in 2024 and purchased from the nuclear plants that were subsequently offset by PTC. Gas Contracts—PSEG Power sells wholesale natural gas, primarily through an index based full-requirements Basic Gas Supply Service (BGSS) contract with PSE&G to meet the gas supply requirements of PSE&G’s customers. The BGSS contract remains in effect unless terminated by either party with a two-year notice. Based upon the availability of natural gas, storage and pipeline capacity beyond PSE&G’s daily needs, PSEG Power also sells gas and pipeline capacity to other counterparties under bilateral contracts. The performance obligation is primarily the delivery of gas which is satisfied over time. Revenue is recognized as gas is delivered or pipeline capacity is released. PSEG LI Contract—PSEG LI has a contract with LIPA which generates revenues. PSEG LI’s subsidiary, Long Island Electric Utility Servco, LLC (Servco) records costs which are recovered from LIPA and records the recovery of those costs as revenues when Servco is a principal in the transaction. In September 2025, the LIPA board of trustees approved a five-year extension of the contract. See Amended OSA below for further information. Other Revenues from Contracts with Customers PSEG Power had contracted to provide energy management and fuel procurement services for LIPA. Revenue was recognized over time as services were rendered. This agreement expired in December 2025. Revenues Unrelated to Contracts with Customers PSEG Power’s revenues unrelated to contracts with customers include electric, gas and certain energy-related transactions accounted for in accordance with Derivatives and Hedging accounting guidance. See Note 10. Financial Risk Management Activities for further discussion. Energy Holdings generates lease revenues which are recorded pursuant to lease accounting guidance. Disaggregation of Revenues
(A) Includes revenues applicable to PSEG Power, PSEG LI and Energy Holdings. (B) Includes primarily revenues from appliance repair services and the sale of solar renewable energy credits (SRECs) at auction at PSE&G. PSEG Power & Other includes PSEG LI’s OSA with LIPA and PSEG Power’s energy management fee with LIPA. (C) Includes alternative revenues at PSE&G, including CIP, Green Program Recovery Charge (GPRC) and transmission over or under recoveries, which are authorized to be collected or refunded in the future periods, and derivative contracts and lease contracts at PSEG Power & Other. Contract Balances PSE&G PSE&G did not have any material contract balances (rights to consideration for services already provided or obligations to provide services in the future for consideration already received) as of March 31, 2026 and December 31, 2025. Substantially all of PSE&G’s accounts receivable and unbilled revenues result from contracts with customers that are priced at tariff rates. The allowance for credit losses represented approximately 12% of accounts receivable (including unbilled revenues) as of both March 31, 2026 and December 31, 2025. Accounts Receivable—Allowance for Credit Losses PSE&G’s accounts receivable, including unbilled revenues, is primarily comprised of utility customer receivables for the provision of electric and gas service and appliance services, and are reported on the balance sheet as gross outstanding amounts adjusted for an allowance for credit losses. The allowance for credit losses reflects PSE&G’s best estimate of losses on the account balances. The allowance is based on PSE&G’s projection of accounts receivable aging, historical experience, economic factors and other currently available evidence. PSE&G’s electric bad debt expense is recoverable through its Societal Benefits Clause (SBC) mechanism. The following provides a reconciliation of PSE&G’s allowance for credit losses for the three months ended March 31, 2026 and 2025:
PSEG Power & Other PSEG Power generally collects consideration upon satisfaction of performance obligations, and therefore, PSEG Power had no material contract balances as of March 31, 2026 and December 31, 2025. PSEG Power’s accounts receivable include amounts resulting from contracts with customers and other contracts which are out of scope of accounting guidance for revenues from contracts with customers. The majority of these accounts receivable are subject to master netting agreements. As a result, accounts receivable resulting from contracts with customers and receivables unrelated to contracts with customers are netted within Accounts Receivable and Accounts Payable on the Condensed Consolidated Balance Sheets. PSEG Power’s accounts receivable consist mainly of revenues from energy and ancillary services sold directly to ISOs and other counterparties. In the wholesale energy markets in which PSEG Power operates, payment for services rendered and products transferred are typically due within 30 days of delivery. As such, there is little credit risk associated with these receivables. PSEG Power did not record an allowance for credit losses for these receivables as of March 31, 2026 or December 31, 2025. PSEG Power monitors the status of its counterparties on an ongoing basis to assess whether there are any anticipated credit losses. PSEG LI did not have any material contract balances as of March 31, 2026 and December 31, 2025. Remaining Performance Obligations under Fixed Consideration Contracts PSEG primarily records revenues as allowed by the guidance, which states that if an entity has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date, the entity may recognize revenue in the amount to which the entity has a right to invoice. PSEG has future performance obligations under contracts with fixed consideration as follows: Capacity Revenues from the PJM Annual Base Residual and Incremental Auctions—The Base Residual Auction is generally conducted annually three years in advance of the operating period. However, changes to capacity market rules have resulted in auction suspensions and delays so that recent auctions have been run closer in time to their operating periods. In July 2024 the results of the 2025/2026 auction were released, in July 2025 the results of the 2026/2027 auction were released and in December 2025 the results of the 2027/2028 auction were released. PSEG Power expects to realize the following average capacity prices resulting from the base and incremental auctions, including unit specific bilateral contracts for previously cleared capacity obligations.
Amended OSA—PSEG LI has been operating LIPA’s electric T&D system in Long Island, New York since 2014 under a 12-year OSA with LIPA that expired on December 31, 2025, with annual fixed and variable components. The fixed fee for the provision of services thereunder in 2025 was approximately $45 million. In December 2025, PSEG LI entered into a five-year extension of the OSA ending on December 31, 2030. The fixed fee for the provision of services in 2026 and 2027 is approximately $43 million, escalating to approximately $47 million in 2028 and updated annually based on the change in the Consumer Price Index through the remainder of the contract. A competitor in the contract bidding process filed litigation against LIPA challenging the process. LIPA filed a motion to dismiss the competitor’s claim as untimely, which was granted by the New York Supreme Court. The competitor filed an appeal in January 2026. |

| Variable Interest Entity [Line Items] | |
| Variable Interest Entities (VIEs) | Note 3. Variable Interest Entity (VIE) VIE for which PSEG LI is the Primary Beneficiary PSEG LI consolidates Servco, a marginally capitalized VIE, which was created for the purpose of operating LIPA’s T&D system in Long Island, New York as well as providing administrative support functions to LIPA. PSEG LI is the primary beneficiary of Servco because it directs the operations of Servco, the activity that most significantly impacts Servco’s economic performance and it has the obligation to absorb losses of Servco that could potentially be significant to Servco. Such losses would be immaterial to PSEG. Pursuant to the OSA, Servco’s operating costs are paid entirely by LIPA, and therefore, PSEG LI’s risk is limited related to the activities of Servco. PSEG LI has no current obligation to provide direct financial support to Servco. In addition to payment of Servco’s operating costs as provided for in the OSA, PSEG LI receives an annual contract management fee. PSEG LI’s annual contract management fee, in certain situations, could be partially offset by Servco’s annual storm costs that are denied reimbursement by the Federal Emergency Management Agency, limited contingent liabilities and penalties for failing to meet certain performance metrics. For transactions in which Servco acts as principal and controls the services provided to LIPA, such as transactions with its employees for labor and labor-related activities, including pension and OPEB-related transactions, Servco records revenues and the related pass-through expenditures separately in Operating Revenues and Operation and Maintenance (O&M) Expense, respectively. Servco recorded $151 million and $152 million for the three months ended March 31, 2026 and 2025, respectively, of O&M expense, the full reimbursement of which was reflected in Operating Revenues. For transactions in which Servco acts as an agent for LIPA, it records revenues and the related expenses on a net basis, resulting in no impact on PSEG’s Condensed Consolidated Statement of Operations. |

| Trust Investments | Note 6. Trust Investments Nuclear Decommissioning Trust (NDT) Fund PSEG Power maintains an external master NDT to fund its share of decommissioning costs for its five nuclear facilities. The trust contains two separate funds: a qualified fund and a nonqualified fund. Section 468A of the Internal Revenue Code limits the amount of money that can be contributed into a qualified fund. The funds are managed by third-party investment managers who operate under investment guidelines developed by PSEG Power. The following tables show the amortized costs basis, gross unrealized gains and losses and fair values for the securities held in the NDT Fund.
(A) The NDT Fund Investments table excludes cash and foreign currency of $1 million as of March 31, 2026, which is part of the NDT Fund.
(A) The NDT Fund Investments table excludes cash and foreign currency of $1 million as of December 31, 2025, which is part of the NDT Fund. Net unrealized gains (losses) on debt securities of $(38) million (after-tax) were included in Accumulated Other Comprehensive Loss (AOCL) on PSEG’s Condensed Consolidated Balance Sheet as of March 31, 2026. The portion of net unrealized gains (losses) recognized in the first quarter of 2026 related to equity securities still held as of March 31, 2026 was $(16) million. The amounts in the preceding tables do not include receivables and payables for NDT Fund transactions which have not settled at the end of each period. Such amounts are included in Accounts Receivable and Accounts Payable on the Condensed Consolidated Balance Sheets as shown in the following table.
The following table shows the value of securities in the NDT Fund that have been in an unrealized loss position for less than and greater than 12 months.
(A) Equity Securities—Investments in marketable equity securities within the NDT Fund are primarily in common stocks within a broad range of industries and sectors. Unrealized gains and losses on these securities are recorded in Net Income. (B) Debt Securities (Government)—Unrealized gains and losses on these securities are recorded in Accumulated Other Comprehensive Income (Loss). The unrealized losses on PSEG Power’s NDT investments in U.S. Treasury obligations and Federal Agency mortgage-backed securities were caused by interest rate changes. PSEG Power also has investments in municipal bonds. It is not expected that these securities will settle for less than their amortized cost. PSEG Power does not intend to sell these securities, nor will it be more-likely-than-not required to sell before recovery of their amortized cost. PSEG Power did not recognize credit losses for U.S. Treasury obligations and Federal Agency mortgage-backed securities because these investments are guaranteed by the U.S. government or an agency of the U.S. government. PSEG Power did not recognize credit losses for municipal bonds because they are primarily investment grade securities. (C) Debt Securities (Corporate)—Unrealized gains and losses on these securities are recorded in Accumulated Other Comprehensive Income (Loss). Unrealized losses were due to market declines. It is not expected that these securities would settle for less than their amortized cost. PSEG Power does not intend to sell these securities, nor will it be more-likely-than-not required to sell before recovery of their amortized cost. PSEG Power did not recognize credit losses for corporate bonds because they are primarily investment grade securities. The proceeds from the sales of and the net gains (losses) on securities in the NDT Fund were:
(A) The cost of these securities was determined on the basis of specific identification. The NDT Fund debt securities held as of March 31, 2026 had the following maturities:
PSEG Power periodically assesses individual debt securities whose fair value is less than amortized cost to determine whether the investments are impaired. For these securities, management considers its intent to sell or requirement to sell a security prior to expected recovery. In those cases where a sale is expected, any impairment would be recorded through earnings. For fixed income securities where there is no intent to sell or likely requirement to sell, management evaluates whether credit loss is a component of the impairment. If so, that portion is recorded through earnings while the noncredit loss component is recorded through Accumulated Other Comprehensive Income (Loss). Any subsequent recoveries of the noncredit loss component of the impairment would be recorded through Accumulated Other Comprehensive Income (Loss). Any subsequent recoveries of the credit loss component would be recognized through earnings. The assessment of fair market value compared to cost is applied on a weighted average basis taking into account various purchase dates and initial cost of the securities. Rabbi Trust PSEG maintains certain unfunded nonqualified benefit plans to provide supplemental retirement and deferred compensation benefits to certain key employees. Certain assets related to these plans have been set aside in a grantor trust commonly known as a “Rabbi Trust.” The following tables show the amortized cost basis, gross unrealized gains and losses and fair values for the securities held in the Rabbi Trust.
Net unrealized gains (losses) on debt securities of $(19) million (after-tax) were included in AOCL on PSEG’s Condensed Consolidated Balance Sheet as of March 31, 2026. The portion of net unrealized gains (losses) recognized during first quarter of 2026 related to equity securities still held as of March 31, 2026 was approximately $(1) million. The amounts in the preceding tables do not include receivables and payables for Rabbi Trust Fund transactions which have not settled at the end of each period. Such amounts were immaterial as of March 31, 2026 and December 31, 2025. The following table shows the value of securities in the Rabbi Trust Fund that have been in an unrealized loss position for less than 12 months and greater than 12 months.
(A) Debt Securities (Government)—Unrealized gains and losses on these securities are recorded in Accumulated Other Comprehensive Income (Loss). The unrealized losses on PSEG’s Rabbi Trust investments in U.S. Treasury obligations and Federal Agency mortgage-backed securities were caused by interest rate changes. PSEG also has investments in municipal bonds. It is not expected that these securities will settle for less than their amortized cost. PSEG does not intend to sell these securities, nor will it be more-likely-than-not required to sell before recovery of their amortized cost. PSEG did not recognize credit losses for U.S. Treasury obligations and Federal Agency mortgage-backed securities because these investments are guaranteed by the U.S. government or an agency of the U.S. government. PSEG did not recognize credit losses for municipal bonds because they are primarily investment grade securities.

PSEG periodically assesses individual debt securities whose fair value is less than amortized cost to determine whether the investments are considered to be impaired. For these securities, management considers its intent to sell or requirement to sell a security prior to expected recovery. In those cases where a sale is expected, any impairment would be recorded through earnings. For fixed income securities where there is no intent to sell or likely requirement to sell, management evaluates whether credit loss is a component of the impairment. If so, that portion is recorded through earnings while the noncredit loss component is recorded through Accumulated Other Comprehensive Income (Loss). Any subsequent recoveries of the noncredit loss component of the impairment would be recorded through Accumulated Other Comprehensive Income (Loss). Any subsequent recoveries of the credit loss component would be recognized through earnings. The assessment of fair market value compared to cost is applied on a weighted average basis taking into account various purchase dates and initial cost of the securities. The fair value of the Rabbi Trust related to PSE&G and PSEG Power & Other is detailed as follows:

| Trust Investments | Note 6. Trust Investments Nuclear Decommissioning Trust (NDT) Fund PSEG Power maintains an external master NDT to fund its share of decommissioning costs for its five nuclear facilities. The trust contains two separate funds: a qualified fund and a nonqualified fund. Section 468A of the Internal Revenue Code limits the amount of money that can be contributed into a qualified fund. The funds are managed by third-party investment managers who operate under investment guidelines developed by PSEG Power. The following tables show the amortized costs basis, gross unrealized gains and losses and fair values for the securities held in the NDT Fund.
(A) The NDT Fund Investments table excludes cash and foreign currency of $1 million as of March 31, 2026, which is part of the NDT Fund.
(A) The NDT Fund Investments table excludes cash and foreign currency of $1 million as of December 31, 2025, which is part of the NDT Fund. Net unrealized gains (losses) on debt securities of $(38) million (after-tax) were included in Accumulated Other Comprehensive Loss (AOCL) on PSEG’s Condensed Consolidated Balance Sheet as of March 31, 2026. The portion of net unrealized gains (losses) recognized in the first quarter of 2026 related to equity securities still held as of March 31, 2026 was $(16) million. The amounts in the preceding tables do not include receivables and payables for NDT Fund transactions which have not settled at the end of each period. Such amounts are included in Accounts Receivable and Accounts Payable on the Condensed Consolidated Balance Sheets as shown in the following table.
The following table shows the value of securities in the NDT Fund that have been in an unrealized loss position for less than and greater than 12 months.
(A) Equity Securities—Investments in marketable equity securities within the NDT Fund are primarily in common stocks within a broad range of industries and sectors. Unrealized gains and losses on these securities are recorded in Net Income. (B) Debt Securities (Government)—Unrealized gains and losses on these securities are recorded in Accumulated Other Comprehensive Income (Loss). The unrealized losses on PSEG Power’s NDT investments in U.S. Treasury obligations and Federal Agency mortgage-backed securities were caused by interest rate changes. PSEG Power also has investments in municipal bonds. It is not expected that these securities will settle for less than their amortized cost. PSEG Power does not intend to sell these securities, nor will it be more-likely-than-not required to sell before recovery of their amortized cost. PSEG Power did not recognize credit losses for U.S. Treasury obligations and Federal Agency mortgage-backed securities because these investments are guaranteed by the U.S. government or an agency of the U.S. government. PSEG Power did not recognize credit losses for municipal bonds because they are primarily investment grade securities. (C) Debt Securities (Corporate)—Unrealized gains and losses on these securities are recorded in Accumulated Other Comprehensive Income (Loss). Unrealized losses were due to market declines. It is not expected that these securities would settle for less than their amortized cost. PSEG Power does not intend to sell these securities, nor will it be more-likely-than-not required to sell before recovery of their amortized cost. PSEG Power did not recognize credit losses for corporate bonds because they are primarily investment grade securities. The proceeds from the sales of and the net gains (losses) on securities in the NDT Fund were:

The assessment of fair market value compared to cost is applied on a weighted average basis taking into account various purchase dates and initial cost of the securities. Rabbi Trust PSEG maintains certain unfunded nonqualified benefit plans to provide supplemental retirement and deferred compensation benefits to certain key employees. Certain assets related to these plans have been set aside in a grantor trust commonly known as a “Rabbi Trust.” The following tables show the amortized cost basis, gross unrealized gains and losses and fair values for the securities held in the Rabbi Trust.
Net unrealized gains (losses) on debt securities of $(19) million (after-tax) were included in AOCL on PSEG’s Condensed Consolidated Balance Sheet as of March 31, 2026. The portion of net unrealized gains (losses) recognized during first quarter of 2026 related to equity securities still held as of March 31, 2026 was approximately $(1) million. The amounts in the preceding tables do not include receivables and payables for Rabbi Trust Fund transactions which have not settled at the end of each period. Such amounts were immaterial as of March 31, 2026 and December 31, 2025. The following table shows the value of securities in the Rabbi Trust Fund that have been in an unrealized loss position for less than 12 months and greater than 12 months.

| Pension and Other Postretirement Benefits (OPEB) | Note 7. Pension and Other Postretirement Benefits (OPEB) PSEG sponsors qualified and nonqualified pension plans and OPEB plans covering PSEG’s and its participating affiliates’ current and former employees who meet certain eligibility criteria. PSEG and PSE&G are required to record the under or over funded positions of their defined benefit pension and OPEB plans on their respective balance sheets. Such funding positions are required to be measured as of the date of their respective year-end Consolidated Balance Sheets. The following table provides the components of net periodic benefit costs (credits) relating to all qualified and nonqualified pension and OPEB plans on an aggregate basis for PSEG, excluding Servco. Amounts shown do not reflect the impacts of capitalization, co-owner allocations and certain regulatory orders. Only the service cost component is eligible for capitalization, when applicable.
Pension and OPEB costs (credits) for PSE&G and PSEG Power & Other are detailed as follows:
PSEG will make future pension contributions to satisfy Internal Revenue Service (IRS) minimum funding requirements. Depending on market performance, actuarial assumptions and financial estimates, PSEG could contribute up to $100 million to its pension plan in 2026. Servco Pension and OPEB Servco sponsors a qualified pension plan and OPEB plan covering its employees who meet certain eligibility criteria. Under the OSA, employee benefit costs for these plans are funded by LIPA. See Note 3. Variable Interest Entity. The OPEB obligation, as well as the offsetting long-term receivable, is separately presented on the Condensed Consolidated Balance Sheet of PSEG. Prepaid pension costs are included in Other Noncurrent Assets with an offsetting liability in Other Noncurrent Liabilities. Pension and OPEB costs of Servco are accounted for according to the OSA. Servco recognizes expenses for contributions to its pension plan trust and for OPEB payments made to retirees. Operating Revenues are recognized for the reimbursement of these costs. Servco plans to contribute $15 million into its pension plan in 2026. Servco’s pension-related revenues and costs were $4 million and $6 million for the three months ended March 31, 2026 and 2025, respectively. The OPEB-related revenues earned and costs incurred was $3 million for each of the three months ended March 31, 2026 and 2025. |

| Commitments and Contingent Liabilities | Note 8. Commitments and Contingent Liabilities Guaranteed Obligations PSEG Power’s activities primarily involve the purchase and/or sale of energy, nuclear fuel and other related products under transportation, physical, financial and forward contracts at fixed and variable prices. These transactions are with numerous counterparties and brokers that may require cash, letters of credit or guarantees as a form of credit support. PSEG Power has unconditionally guaranteed payments to counterparties on behalf of its subsidiaries in commodity-related transactions in order to • support current exposure, interest and other costs on sums due and payable in the ordinary course of business, and • obtain unsecured credit thresholds from counterparties. PSEG Power is subject to • counterparty collateral calls due to margining provisions included in commodity contracts, and • certain creditworthiness standards as guarantor under performance guarantees of its subsidiaries. Under these agreements, guarantees cover credit extended between entities and can be reciprocal in nature. The exposure between counterparties can move in either direction. In order for PSEG Power to incur a liability for the face value of the outstanding guarantees, • its subsidiaries would have to fully utilize the credit granted to them by every counterparty to whom PSEG Power has provided a guarantee, and • the net position of the related contracts would have to be “out-of-the-money”, including payables (if the contracts are terminated, PSEG Power would owe money to the counterparties). PSEG Power believes the probability of this result is unlikely. For this reason, PSEG Power believes that the current exposure at any point in time is a more meaningful representation of the potential liability under these guarantees. Current exposure consists of the net of accounts receivable and accounts payable and the forward value on open positions, less any collateral posted. Changes in commodity prices can have a material impact on collateral requirements under such contracts, which are posted and received primarily in the form of cash and letters of credit. PSEG Power also routinely enters into futures and options transactions primarily for electricity as part of its operations and for natural gas from time to time. These futures contracts usually require a cash margin deposit with brokers, which can change based on market movement and in accordance with exchange rules. In addition to the guarantees discussed above, PSEG Power has also provided payment guarantees to third parties and regulatory authorities on behalf of its affiliated companies. These guarantees support various other non-commodity related obligations. The following table shows the face value of PSEG Power’s outstanding guarantees, current exposure and margin positions as of March 31, 2026 and December 31, 2025.
As part of determining credit exposure, PSEG Power nets receivables and payables with the corresponding net fair values of energy contracts. See Note 10. Financial Risk Management Activities for further discussion. In accordance with PSEG’s accounting policy, where it is applicable, cash (received)/deposited is allocated against derivative asset and liability positions with the same counterparty on the face of the Condensed Consolidated Balance Sheet. The remaining balances of net cash (received)/deposited after allocation are generally included in Accounts Payable and Accounts Receivable, respectively. In addition to amounts for outstanding guarantees, current exposure and margin positions, PSEG and PSEG Power have posted letters of credit to support PSEG Power’s various other non-energy contractual and environmental obligations. See Other Letters of Credit in the preceding table. Environmental Matters Newark Bay Complex The Newark Bay Complex is a tidal estuary in northern New Jersey that includes Newark Bay, as well as portions of the Passaic River, the Hackensack River and other surrounding waterways. The U.S. Environmental Protection Agency (EPA) has designated various portions of the Newark Bay Complex as federal Superfund sites that must be investigated and remediated under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA). Lower Passaic River Study Area The EPA has determined that a 17-mile stretch of the Passaic River (Lower Passaic River Study Area (LPRSA)) in New Jersey is a “Superfund” site. PSE&G and certain of its predecessors conducted operations at properties in this area, including at one site that was transferred to PSEG Power. The EPA has announced two separate cleanup plans for the Lower 8.3 miles and Upper 9 miles of the LPRSA. The EPA’s plan for the Lower 8.3 miles involves dredging and capping sediments at an estimated cost of $2.3 billion, and its plan for the Upper 9 miles involves dredging and capping sediments at an estimated cost of $550 million. Additional cleanup work may be required depending on the results of these initial phases of work. Occidental Chemical Corporation (Occidental) has voluntarily completed the design of the cleanup plan for the Lower 8.3 miles and has received an EPA Unilateral Administrative Order directing it to design the cleanup plan for the Upper 9 miles. Occidental has filed two lawsuits against PSE&G and others to attempt to recover costs associated with its past investigation and cleanup work within the LPRSA and to obtain a declaratory judgment of parties’ shares of any future costs. PSEG cannot predict the outcome of the litigation. In January 2026, Occidental’s parent company completed the sale of Occidental to a third party and identified a new company, Environmental Resource Holdings, LLC, as the successor to Occidental’s environmental liability at the Newark Bay Complex and elsewhere. PSE&G and others have filed suit for a declaratory judgment that Occidental remains liable for investigation and cleanup costs within the Newark Bay Complex and elsewhere. The EPA finalized and received court approval of a settlement with 82 parties who have agreed to pay $150 million to resolve their LPRSA CERCLA liability, in whole or in part. This settlement is being appealed. PSE&G and PSEG Power are not included in the settlement, but the EPA sent PSE&G, Occidental, and several other Potentially Responsible Parties (PRPs) a letter in March 2022 inviting them to submit to the EPA individually or jointly an offer to fund or participate in the next stages of the remediation. PSEG submitted a good faith offer to the EPA in June 2022 on behalf of PSE&G and PSEG Power. PSEG understands that the EPA is evaluating its offer. As of March 31, 2026, PSEG has approximately $66 million accrued for this matter. PSE&G has an Environmental Costs Liability of $53 million and a corresponding Regulatory Asset based on its continued ability to recover such costs in its rates. PSEG Power has an Environmental Costs Liability of $13 million. The outcome of this matter is uncertain, and until (i) a final remedy for the entire LPRSA is selected and an agreement is reached by the PRPs to fund it, (ii) PSE&G’s and PSEG Power’s respective shares of the costs are determined, and (iii) PSE&G’s ability to recover the costs in its rates is determined, it is not possible to predict this matter’s ultimate impact on PSEG’s financial statements. It is possible that PSE&G and PSEG Power will record additional costs beyond what they have accrued, and that such costs could be material, but PSEG cannot at the current time estimate the amount or range of any additional costs. Newark Bay Study Area The EPA has established the Newark Bay Study Area, which is an extension of the LPRSA and includes Newark Bay and portions of surrounding waterways. The EPA has notified PSEG and 21 other PRPs of their potential liability. PSE&G and PSEG Power are unable to estimate their respective portions of any loss or possible range of loss related to this matter. In December 2018, PSEG Power completed the sale of the site of the Hudson electric generating station. PSEG Power contractually transferred all land rights and structures on the Hudson site to a third-party purchaser, along with the assumption of the environmental liabilities for the site. Natural Resource Damage Claims New Jersey and certain federal regulators have alleged that PSE&G, PSEG Power and 56 other PRPs may be liable for natural resource damages within the LPRSA. In particular, PSE&G, PSEG Power and other PRPs received notice from federal regulators of the regulators’ intent to move forward with a series of studies assessing potential damages to natural resources at the Diamond Alkali Superfund site, which includes the LPRSA and the Newark Bay Study Area. PSE&G and PSEG Power are unable to estimate their respective portions of any possible loss or range of loss related to this matter. Hackensack River EPA has designated approximately 23 river miles of the Lower Hackensack River as a federal Superfund site. The site runs from the river’s confluence with Newark Bay north to the Oradell Dam. PSE&G and certain of its predecessors conducted operations at properties in this area, including at the Hudson, Bergen and Kearny generating stations that were transferred to PSEG Power. PSEG Power subsequently contractually transferred all land rights and structures on the Hudson generating station site to a third-party purchaser, along with the assumption of the environmental liabilities for that site. In 2024, the EPA identified PSE&G and four other parties as PRPs for the site and requested that they voluntarily perform a technical study of a portion of the Lower Hackensack River designated as “Operable Unit 2.” PSE&G and PSEG Power have agreed to participate in the technical study. PSE&G and PSEG Power do not believe participation in the technical study will have a material impact on their results of operations and financial condition; however, future costs related to this matter could be material. In September 2025, the EPA identified PSE&G and three other parties as PRPs for a new portion of the Lower Hackensack River. EPA requested the PRPs voluntarily perform a technical study for this incremental portion designated as “Operable Unit 3.” PSE&G and PSEG Power are considering the EPA’s request. We cannot predict the outcome of this matter. Manufactured Gas Plant (MGP) Remediation Program PSE&G is working with the New Jersey Department of Environmental Protection (NJDEP) to assess, investigate and remediate environmental conditions at its former MGP sites. To date, 38 sites requiring some level of remedial action have been identified. Based on its current studies, PSE&G has determined that the estimated cost to remediate all MGP sites to completion could range between $176 million and $193 million on an undiscounted basis, including its $53 million share for the Passaic River as discussed above. Since no amount within the range is considered to be most likely, PSE&G has recorded a liability of $176 million as of March 31, 2026. Of this amount, $24 million was recorded in Other Current Liabilities and $152 million was reflected as in Noncurrent Liabilities. PSE&G has recorded a $176 million Regulatory Asset with respect to these costs. PSE&G periodically updates its studies taking into account any new regulations or new information which could impact future remediation costs and adjusts its recorded liability accordingly. PSE&G completed sampling in the Passaic River in 2020 to delineate coal tar from certain MGP sites that abut the Passaic River Superfund site. PSEG cannot determine at this time the magnitude of any impact on the Passaic River Superfund remedy. Legacy Environmental Obligations at Former Fossil Generating Sites PSEG Power has retained ownership of certain liabilities excluded from the 2022 sale of its fossil generation portfolio. These liabilities primarily relate to obligations under the New Jersey Industrial Site Recovery Act (ISRA) and the Connecticut Transfer Act (CTA) to investigate and remediate PSEG Power’s two formerly owned generating station sites in Connecticut, and six formerly owned generating station sites in New Jersey. In addition, PSEG Power still owns two former generating station sites in New Jersey that triggered ISRA in 2015. PSEG Power is in the process of fulfilling its obligations under the New Jersey ISRA and the CTA to investigate these sites. It will require multiple years and comprehensive environmental sampling to understand the extent of and to carry out the required remediation. At this stage in the remediation process, the full remediation costs are not estimable, but given the number and operating history of the facilities in the portfolio, the full remediation costs will likely be material in the aggregate. The costs could potentially include costs for, among other things, excavating soil, implementation of institutional controls, and the construction, operation and maintenance of engineering controls. In May 2024, the EPA finalized revisions to the coal combustion residuals rule (CCR Rule) which established new requirements for the investigation and, if necessary, the cleanup of certain types of coal ash placed at certain fossil generation station sites, including certain sites owned or formerly owned by PSEG Power. PSEG is in the process of investigating each of the sites that PSEG Power currently owns that are subject to the CCR Rule, as well as sites that were formerly owned that are subject to the CCR Rule where PSEG Power retained certain environmental obligations to investigate and, if necessary, remediate. PSEG is currently unable to estimate the impact of the CCR Rule, but it could have a material impact on PSEG’s business, results of operations and cash flows. Basic Generation Service (BGS), BGSS and ZECs Each year, PSE&G obtains its electric supply requirements through annual New Jersey BGS auctions for two categories of customers that choose not to purchase electric supply from third-party suppliers. The first category is residential and smaller commercial and industrial customers (BGS-Residential Small Commercial Pricing (RSCP)). The second category is larger customers that exceed a BPU-established load (kW) threshold (BGS-Commercial and Industrial Energy Pricing (CIEP)). Pursuant to applicable BPU rules, PSE&G enters into the Supplier Master Agreements with the winners of these RSCP and CIEP BGS auctions to purchase BGS for PSE&G’s load requirements. The winners of the RSCP and CIEP auctions are responsible for fulfilling all the requirements of a PJM load-serving entity including the provision of capacity, energy, ancillary services and any other services required by PJM. As such, prices set through these auctions are impacted by FERC-approved prices set in the PJM capacity auctions, which significantly increased for the 2025/2026 and subsequent auction years. See Note 2. Revenues for additional information. BGS suppliers assume all volume risk and customer migration risk and must satisfy New Jersey’s renewable portfolio standards. The BGS-CIEP auction is for a one-year supply period from June 1 to May 31 with the BGS-CIEP auction price measured in dollars per MW-day for capacity. The final price for the BGS-CIEP auction year commencing June 1, 2026 is $677.73 per MW-day, replacing the BGS-CIEP auction year price ending May 31, 2026 of $696.05 per MW-day. Energy for BGS-CIEP is priced at hourly PJM locational marginal prices for the contract period. PSE&G contracts for its anticipated BGS-RSCP load on a three-year rolling basis, whereby each year one-third of the load is procured for a three-year period. The contract prices in dollars per MWh for the BGS-RSCP supply, as well as the approximate load, are as follows:
(A) Prices set in the 2026 BGS auction will become effective on June 1, 2026 when the 2023 BGS auction agreements expire. PSE&G has a full-requirements contract with PSEG Power to meet the gas supply requirements of PSE&G’s gas customers. PSEG Power has entered into hedges for a portion of these anticipated BGSS obligations, as permitted by the BPU. The BPU permits PSE&G to recover the cost of gas hedging up to 115 billion cubic feet or 80% of its residential gas supply annual requirements through the BGSS tariff. Current plans call for PSEG Power to hedge on behalf of PSE&G approximately 70 billion cubic feet or 50% of its residential gas supply annual requirements. For additional information, see Note 17. Related-Party Transactions. Pursuant to a process established by the BPU, New Jersey EDCs, including PSE&G, were required to purchase ZECs from eligible nuclear plants selected by the BPU. In April 2021, PSEG Power’s Salem 1, Salem 2 and Hope Creek nuclear plants were awarded ZECs for the three-year eligibility period from June 2022 through May 2025. PSE&G purchased the ZECs on a monthly basis with payment to be made annually following completion of each energy year. The ZEC program ended effective June 1, 2025, and the final ZEC payment from PSE&G to PSEG Power settled in August 2025. See Note 2. Revenues for additional information.
FERC Matters FERC has completed a non-public investigation of the Roseland-Pleasant Valley (RPV) transmission project. In December 2024, FERC approved an agreement between PSE&G and FERC Enforcement Staff resolving its investigation. The agreement included a $6.6 million civil penalty and the implementation of certain compliance requirements, in addition to the process improvements that PSE&G has already implemented. It also included a statement that nothing in the agreement reflected a challenge by FERC Enforcement to the end-of-life determination relative to the project and that no disgorgement had been sought. In both a December 2024 proceeding related to PJM’s annual cost allocation filing and in PSE&G’s 2025 annual formula rate true-up filing, an intervenor raised an objection related to the recovery of costs for the RPV project. FERC rejected the first challenge as procedurally out of scope and has not acted on, and does not need to act on, the second filing. In January 2026, that same intervenor filed a FERC complaint against PSE&G requesting that FERC set a hearing on the recovery of these costs. PSE&G has sought dismissal of the complaint but cannot predict the outcome of this matter. BPU Audit of PSE&G In 2020, the BPU ordered the commencement of a comprehensive affiliate and management audit of PSE&G. It has been more than ten years since the BPU last conducted a management and affiliate audit of this kind of PSE&G, which is initiated periodically as required by New Jersey statutes/regulations. Phase 1 of the audit reviews affiliate relations and cost allocation between PSE&G and its affiliates, including an analysis of the relationship between PSE&G and PSEG Energy Resources & Trade, LLC, a wholly owned subsidiary of PSEG Power over the past ten years, and between PSE&G and PSEG LI. Phase 2 is a comprehensive management audit, which addresses, among other things, executive management, corporate governance, system operations, human resources, cyber security, compliance with customer protection requirements and customer safety. The audit officially began in late May 2021. The BPU Audit Staff submitted the final audit report to the BPU in June 2023. The BPU has not yet determined which audit recommendations it will require PSE&G to implement. It is not possible at this time to predict the outcome of this matter. Litigation Sewaren 7 Construction In June 2018, a complaint was filed in federal court in Newark, New Jersey against PSEG Fossil LLC, which at the time was a wholly owned subsidiary of PSEG Power, regarding an ongoing dispute with Durr Mechanical Construction, Inc. (Durr), a contractor on the Sewaren 7 project. Among other things, Durr sought damages of $93 million and alleges that PSEG Power withheld money owed to Durr and that PSEG Power’s intentional conduct led to the inability of Durr to obtain prospective contracts. PSEG Power intends to vigorously defend against these allegations. In January 2021, the court partially granted PSEG Power’s motion to dismiss certain claims, reducing the amount claimed to $68 million. In December 2018, Durr filed for Chapter 11 bankruptcy in the federal court in the Southern District of New York (SDNY). The SDNY bankruptcy court has allowed the New Jersey litigation to proceed. PSEG Power has accrued an amount related to outstanding invoices which does not reflect an assessment of claims and potential counterclaims in this matter. At this time, PSEG Power cannot predict the outcome of this matter. Sherman Act Antitrust Matter In July 2025, a putative class action complaint was filed in the United States District Court for the District of Maryland against 26 nuclear generation power companies, including PSEG, and two consulting companies. The plaintiffs allege defendants violated federal antitrust laws by conspiring to fix the compensation and exchange information regarding compensation for nuclear generation workers. The alleged class includes all persons employed in nuclear power generation by the defendants and their subsidiaries from 2003 until the present, and the relief sought includes treble damages. PSEG cannot predict the outcome of this matter. Other Litigation and Legal Proceedings PSEG and its subsidiaries are party to various lawsuits in the ordinary course of business. In view of the inherent difficulty in predicting the outcome of such matters, PSEG and PSE&G generally cannot predict the eventual outcome of the pending matters, the timing of the ultimate resolution of these matters, or the eventual loss, fines or penalties related to each pending matter. In accordance with applicable accounting guidance, a liability is accrued when those matters present loss contingencies that are both probable and reasonably estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. PSEG will continue to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established. Based on current knowledge, management does not believe that loss contingencies arising from pending matters, other than the matters described herein, could have a material adverse effect on PSEG’s or PSE&G’s consolidated financial position or liquidity. However, in light of the inherent uncertainties involved in these matters, some of which are beyond PSEG’s control, and the large or indeterminate damages sought in some of these matters, an adverse outcome in one or more of these matters could be material to PSEG’s or PSE&G’s results of operations or liquidity for any particular reporting period. |

| Commitments and Contingent Liabilities | Note 8. Commitments and Contingent Liabilities Guaranteed Obligations PSEG Power’s activities primarily involve the purchase and/or sale of energy, nuclear fuel and other related products under transportation, physical, financial and forward contracts at fixed and variable prices. These transactions are with numerous counterparties and brokers that may require cash, letters of credit or guarantees as a form of credit support. PSEG Power has unconditionally guaranteed payments to counterparties on behalf of its subsidiaries in commodity-related transactions in order to • support current exposure, interest and other costs on sums due and payable in the ordinary course of business, and • obtain unsecured credit thresholds from counterparties. PSEG Power is subject to • counterparty collateral calls due to margining provisions included in commodity contracts, and • certain creditworthiness standards as guarantor under performance guarantees of its subsidiaries. Under these agreements, guarantees cover credit extended between entities and can be reciprocal in nature. The exposure between counterparties can move in either direction. In order for PSEG Power to incur a liability for the face value of the outstanding guarantees, • its subsidiaries would have to fully utilize the credit granted to them by every counterparty to whom PSEG Power has provided a guarantee, and • the net position of the related contracts would have to be “out-of-the-money”, including payables (if the contracts are terminated, PSEG Power would owe money to the counterparties). PSEG Power believes the probability of this result is unlikely. For this reason, PSEG Power believes that the current exposure at any point in time is a more meaningful representation of the potential liability under these guarantees. Current exposure consists of the net of accounts receivable and accounts payable and the forward value on open positions, less any collateral posted. Changes in commodity prices can have a material impact on collateral requirements under such contracts, which are posted and received primarily in the form of cash and letters of credit. PSEG Power also routinely enters into futures and options transactions primarily for electricity as part of its operations and for natural gas from time to time. These futures contracts usually require a cash margin deposit with brokers, which can change based on market movement and in accordance with exchange rules. In addition to the guarantees discussed above, PSEG Power has also provided payment guarantees to third parties and regulatory authorities on behalf of its affiliated companies. These guarantees support various other non-commodity related obligations. The following table shows the face value of PSEG Power’s outstanding guarantees, current exposure and margin positions as of March 31, 2026 and December 31, 2025.
As part of determining credit exposure, PSEG Power nets receivables and payables with the corresponding net fair values of energy contracts. See Note 10. Financial Risk Management Activities for further discussion. In accordance with PSEG’s accounting policy, where it is applicable, cash (received)/deposited is allocated against derivative asset and liability positions with the same counterparty on the face of the Condensed Consolidated Balance Sheet. The remaining balances of net cash (received)/deposited after allocation are generally included in Accounts Payable and Accounts Receivable, respectively. In addition to amounts for outstanding guarantees, current exposure and margin positions, PSEG and PSEG Power have posted letters of credit to support PSEG Power’s various other non-energy contractual and environmental obligations. See Other Letters of Credit in the preceding table. Environmental Matters Newark Bay Complex The Newark Bay Complex is a tidal estuary in northern New Jersey that includes Newark Bay, as well as portions of the Passaic River, the Hackensack River and other surrounding waterways. The U.S. Environmental Protection Agency (EPA) has designated various portions of the Newark Bay Complex as federal Superfund sites that must be investigated and remediated under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA). Lower Passaic River Study Area The EPA has determined that a 17-mile stretch of the Passaic River (Lower Passaic River Study Area (LPRSA)) in New Jersey is a “Superfund” site. PSE&G and certain of its predecessors conducted operations at properties in this area, including at one site that was transferred to PSEG Power. The EPA has announced two separate cleanup plans for the Lower 8.3 miles and Upper 9 miles of the LPRSA. The EPA’s plan for the Lower 8.3 miles involves dredging and capping sediments at an estimated cost of $2.3 billion, and its plan for the Upper 9 miles involves dredging and capping sediments at an estimated cost of $550 million. Additional cleanup work may be required depending on the results of these initial phases of work. Occidental Chemical Corporation (Occidental) has voluntarily completed the design of the cleanup plan for the Lower 8.3 miles and has received an EPA Unilateral Administrative Order directing it to design the cleanup plan for the Upper 9 miles. Occidental has filed two lawsuits against PSE&G and others to attempt to recover costs associated with its past investigation and cleanup work within the LPRSA and to obtain a declaratory judgment of parties’ shares of any future costs. PSEG cannot predict the outcome of the litigation. In January 2026, Occidental’s parent company completed the sale of Occidental to a third party and identified a new company, Environmental Resource Holdings, LLC, as the successor to Occidental’s environmental liability at the Newark Bay Complex and elsewhere. PSE&G and others have filed suit for a declaratory judgment that Occidental remains liable for investigation and cleanup costs within the Newark Bay Complex and elsewhere. The EPA finalized and received court approval of a settlement with 82 parties who have agreed to pay $150 million to resolve their LPRSA CERCLA liability, in whole or in part. This settlement is being appealed. PSE&G and PSEG Power are not included in the settlement, but the EPA sent PSE&G, Occidental, and several other Potentially Responsible Parties (PRPs) a letter in March 2022 inviting them to submit to the EPA individually or jointly an offer to fund or participate in the next stages of the remediation. PSEG submitted a good faith offer to the EPA in June 2022 on behalf of PSE&G and PSEG Power. PSEG understands that the EPA is evaluating its offer. As of March 31, 2026, PSEG has approximately $66 million accrued for this matter. PSE&G has an Environmental Costs Liability of $53 million and a corresponding Regulatory Asset based on its continued ability to recover such costs in its rates. PSEG Power has an Environmental Costs Liability of $13 million. The outcome of this matter is uncertain, and until (i) a final remedy for the entire LPRSA is selected and an agreement is reached by the PRPs to fund it, (ii) PSE&G’s and PSEG Power’s respective shares of the costs are determined, and (iii) PSE&G’s ability to recover the costs in its rates is determined, it is not possible to predict this matter’s ultimate impact on PSEG’s financial statements. It is possible that PSE&G and PSEG Power will record additional costs beyond what they have accrued, and that such costs could be material, but PSEG cannot at the current time estimate the amount or range of any additional costs. Newark Bay Study Area The EPA has established the Newark Bay Study Area, which is an extension of the LPRSA and includes Newark Bay and portions of surrounding waterways. The EPA has notified PSEG and 21 other PRPs of their potential liability. PSE&G and PSEG Power are unable to estimate their respective portions of any loss or possible range of loss related to this matter. In December 2018, PSEG Power completed the sale of the site of the Hudson electric generating station. PSEG Power contractually transferred all land rights and structures on the Hudson site to a third-party purchaser, along with the assumption of the environmental liabilities for the site. Natural Resource Damage Claims New Jersey and certain federal regulators have alleged that PSE&G, PSEG Power and 56 other PRPs may be liable for natural resource damages within the LPRSA. In particular, PSE&G, PSEG Power and other PRPs received notice from federal regulators of the regulators’ intent to move forward with a series of studies assessing potential damages to natural resources at the Diamond Alkali Superfund site, which includes the LPRSA and the Newark Bay Study Area. PSE&G and PSEG Power are unable to estimate their respective portions of any possible loss or range of loss related to this matter. Hackensack River EPA has designated approximately 23 river miles of the Lower Hackensack River as a federal Superfund site. The site runs from the river’s confluence with Newark Bay north to the Oradell Dam. PSE&G and certain of its predecessors conducted operations at properties in this area, including at the Hudson, Bergen and Kearny generating stations that were transferred to PSEG Power. PSEG Power subsequently contractually transferred all land rights and structures on the Hudson generating station site to a third-party purchaser, along with the assumption of the environmental liabilities for that site. In 2024, the EPA identified PSE&G and four other parties as PRPs for the site and requested that they voluntarily perform a technical study of a portion of the Lower Hackensack River designated as “Operable Unit 2.” PSE&G and PSEG Power have agreed to participate in the technical study. PSE&G and PSEG Power do not believe participation in the technical study will have a material impact on their results of operations and financial condition; however, future costs related to this matter could be material. In September 2025, the EPA identified PSE&G and three other parties as PRPs for a new portion of the Lower Hackensack River. EPA requested the PRPs voluntarily perform a technical study for this incremental portion designated as “Operable Unit 3.” PSE&G and PSEG Power are considering the EPA’s request. We cannot predict the outcome of this matter. Manufactured Gas Plant (MGP) Remediation Program PSE&G is working with the New Jersey Department of Environmental Protection (NJDEP) to assess, investigate and remediate environmental conditions at its former MGP sites. To date, 38 sites requiring some level of remedial action have been identified. Based on its current studies, PSE&G has determined that the estimated cost to remediate all MGP sites to completion could range between $176 million and $193 million on an undiscounted basis, including its $53 million share for the Passaic River as discussed above. Since no amount within the range is considered to be most likely, PSE&G has recorded a liability of $176 million as of March 31, 2026. Of this amount, $24 million was recorded in Other Current Liabilities and $152 million was reflected as in Noncurrent Liabilities. PSE&G has recorded a $176 million Regulatory Asset with respect to these costs. PSE&G periodically updates its studies taking into account any new regulations or new information which could impact future remediation costs and adjusts its recorded liability accordingly. PSE&G completed sampling in the Passaic River in 2020 to delineate coal tar from certain MGP sites that abut the Passaic River Superfund site. PSEG cannot determine at this time the magnitude of any impact on the Passaic River Superfund remedy. Legacy Environmental Obligations at Former Fossil Generating Sites PSEG Power has retained ownership of certain liabilities excluded from the 2022 sale of its fossil generation portfolio. These liabilities primarily relate to obligations under the New Jersey Industrial Site Recovery Act (ISRA) and the Connecticut Transfer Act (CTA) to investigate and remediate PSEG Power’s two formerly owned generating station sites in Connecticut, and six formerly owned generating station sites in New Jersey. In addition, PSEG Power still owns two former generating station sites in New Jersey that triggered ISRA in 2015. PSEG Power is in the process of fulfilling its obligations under the New Jersey ISRA and the CTA to investigate these sites. It will require multiple years and comprehensive environmental sampling to understand the extent of and to carry out the required remediation. At this stage in the remediation process, the full remediation costs are not estimable, but given the number and operating history of the facilities in the portfolio, the full remediation costs will likely be material in the aggregate. The costs could potentially include costs for, among other things, excavating soil, implementation of institutional controls, and the construction, operation and maintenance of engineering controls. In May 2024, the EPA finalized revisions to the coal combustion residuals rule (CCR Rule) which established new requirements for the investigation and, if necessary, the cleanup of certain types of coal ash placed at certain fossil generation station sites, including certain sites owned or formerly owned by PSEG Power. PSEG is in the process of investigating each of the sites that PSEG Power currently owns that are subject to the CCR Rule, as well as sites that were formerly owned that are subject to the CCR Rule where PSEG Power retained certain environmental obligations to investigate and, if necessary, remediate. PSEG is currently unable to estimate the impact of the CCR Rule, but it could have a material impact on PSEG’s business, results of operations and cash flows. Basic Generation Service (BGS), BGSS and ZECs Each year, PSE&G obtains its electric supply requirements through annual New Jersey BGS auctions for two categories of customers that choose not to purchase electric supply from third-party suppliers. The first category is residential and smaller commercial and industrial customers (BGS-Residential Small Commercial Pricing (RSCP)). The second category is larger customers that exceed a BPU-established load (kW) threshold (BGS-Commercial and Industrial Energy Pricing (CIEP)). Pursuant to applicable BPU rules, PSE&G enters into the Supplier Master Agreements with the winners of these RSCP and CIEP BGS auctions to purchase BGS for PSE&G’s load requirements. The winners of the RSCP and CIEP auctions are responsible for fulfilling all the requirements of a PJM load-serving entity including the provision of capacity, energy, ancillary services and any other services required by PJM. As such, prices set through these auctions are impacted by FERC-approved prices set in the PJM capacity auctions, which significantly increased for the 2025/2026 and subsequent auction years. See Note 2. Revenues for additional information. BGS suppliers assume all volume risk and customer migration risk and must satisfy New Jersey’s renewable portfolio standards. The BGS-CIEP auction is for a one-year supply period from June 1 to May 31 with the BGS-CIEP auction price measured in dollars per MW-day for capacity. The final price for the BGS-CIEP auction year commencing June 1, 2026 is $677.73 per MW-day, replacing the BGS-CIEP auction year price ending May 31, 2026 of $696.05 per MW-day. Energy for BGS-CIEP is priced at hourly PJM locational marginal prices for the contract period. PSE&G contracts for its anticipated BGS-RSCP load on a three-year rolling basis, whereby each year one-third of the load is procured for a three-year period. The contract prices in dollars per MWh for the BGS-RSCP supply, as well as the approximate load, are as follows:
(A) Prices set in the 2026 BGS auction will become effective on June 1, 2026 when the 2023 BGS auction agreements expire. PSE&G has a full-requirements contract with PSEG Power to meet the gas supply requirements of PSE&G’s gas customers. PSEG Power has entered into hedges for a portion of these anticipated BGSS obligations, as permitted by the BPU. The BPU permits PSE&G to recover the cost of gas hedging up to 115 billion cubic feet or 80% of its residential gas supply annual requirements through the BGSS tariff. Current plans call for PSEG Power to hedge on behalf of PSE&G approximately 70 billion cubic feet or 50% of its residential gas supply annual requirements. For additional information, see Note 17. Related-Party Transactions. Pursuant to a process established by the BPU, New Jersey EDCs, including PSE&G, were required to purchase ZECs from eligible nuclear plants selected by the BPU. In April 2021, PSEG Power’s Salem 1, Salem 2 and Hope Creek nuclear plants were awarded ZECs for the three-year eligibility period from June 2022 through May 2025. PSE&G purchased the ZECs on a monthly basis with payment to be made annually following completion of each energy year. The ZEC program ended effective June 1, 2025, and the final ZEC payment from PSE&G to PSEG Power settled in August 2025. See Note 2. Revenues for additional information.
FERC Matters FERC has completed a non-public investigation of the Roseland-Pleasant Valley (RPV) transmission project. In December 2024, FERC approved an agreement between PSE&G and FERC Enforcement Staff resolving its investigation. The agreement included a $6.6 million civil penalty and the implementation of certain compliance requirements, in addition to the process improvements that PSE&G has already implemented. It also included a statement that nothing in the agreement reflected a challenge by FERC Enforcement to the end-of-life determination relative to the project and that no disgorgement had been sought. In both a December 2024 proceeding related to PJM’s annual cost allocation filing and in PSE&G’s 2025 annual formula rate true-up filing, an intervenor raised an objection related to the recovery of costs for the RPV project. FERC rejected the first challenge as procedurally out of scope and has not acted on, and does not need to act on, the second filing. In January 2026, that same intervenor filed a FERC complaint against PSE&G requesting that FERC set a hearing on the recovery of these costs. PSE&G has sought dismissal of the complaint but cannot predict the outcome of this matter. BPU Audit of PSE&G In 2020, the BPU ordered the commencement of a comprehensive affiliate and management audit of PSE&G. It has been more than ten years since the BPU last conducted a management and affiliate audit of this kind of PSE&G, which is initiated periodically as required by New Jersey statutes/regulations. Phase 1 of the audit reviews affiliate relations and cost allocation between PSE&G and its affiliates, including an analysis of the relationship between PSE&G and PSEG Energy Resources & Trade, LLC, a wholly owned subsidiary of PSEG Power over the past ten years, and between PSE&G and PSEG LI. Phase 2 is a comprehensive management audit, which addresses, among other things, executive management, corporate governance, system operations, human resources, cyber security, compliance with customer protection requirements and customer safety. The audit officially began in late May 2021. The BPU Audit Staff submitted the final audit report to the BPU in June 2023. The BPU has not yet determined which audit recommendations it will require PSE&G to implement. It is not possible at this time to predict the outcome of this matter. Litigation Sewaren 7 Construction In June 2018, a complaint was filed in federal court in Newark, New Jersey against PSEG Fossil LLC, which at the time was a wholly owned subsidiary of PSEG Power, regarding an ongoing dispute with Durr Mechanical Construction, Inc. (Durr), a contractor on the Sewaren 7 project. Among other things, Durr sought damages of $93 million and alleges that PSEG Power withheld money owed to Durr and that PSEG Power’s intentional conduct led to the inability of Durr to obtain prospective contracts.

| Debt and Credit Facilities | Note 9. Debt and Credit Facilities Long-Term Debt Financing Transactions The following long-term debt transactions occurred in the three months ended March 31, 2026: PSE&G • issued $500 million of 4.20% Secured Medium-Term Notes, Series R, due January 2031, • issued $500 million of 5.63% Secured Medium-Term Notes, Series R, due January 2056, and • retired $450 million of 0.95% Secured Medium-Term Notes, Series N, at maturity. Short-Term Liquidity PSEG meets its short-term liquidity requirements, as well as those of PSEG Power, primarily through the issuance of commercial paper and, from time to time, short-term loans. PSE&G maintains its own separate commercial paper program to meet its short-term liquidity requirements. Each commercial paper program is fully back-stopped by its own separate credit facility. The commitments under the $3.8 billion credit facilities are provided by a diverse bank group. As of March 31, 2026, the total available credit capacity was $3.5 billion. In March 2026, PSEG, PSEG Power, and PSE&G executed a two-year extension to their existing $3.75 billion revolving credit facilities, extending the maturity through March 2031, and removed the sustainability linked pricing mechanism associated with the PSEG sublimit of the Master Credit Facility. The $75 million PSEG Power letter of credit facility was also extended through March 2028. As of March 31, 2026, no single institution represented more than 9% of the total commitments in the credit facilities. As of March 31, 2026, PSEG’s liquidity position, including credit facilities and access to external financing, was expected to be sufficient to meet its projected stressed requirements over a 12-month planning horizon. Each of the credit facilities is restricted as to availability and use to the specific companies as listed in the following table; however, if necessary, the PSEG facilities can also be used to support its subsidiaries’ liquidity needs. The total committed credit facilities and available liquidity as of March 31, 2026 were as follows:
(A) Master Credit Facility with sub-limits of $1.5 billion for PSEG and $1.25 billion for PSEG Power; sub-limits can be adjusted pursuant to the terms of the Master Credit Facility agreement. (B) The primary use of PSEG’s and PSE&G’s credit facilities is to support their respective Commercial Paper Programs, under which as of March 31, 2026, PSEG had $165 million commercial paper outstanding at a weighted average interest rate of 4.05% and PSE&G had no commercial paper outstanding. (C) Amounts do not include uncommitted credit facilities or 364-day term loans, if any apply. PSEG Power has uncommitted credit facilities totaling $425 million, which can be utilized for letters of credit. As of March 31, 2026, PSEG Power had $190 million in letters of credit outstanding under these uncommitted credit facilities. PSE&G has an uncommitted credit facility totaling $30 million, which can be utilized for letters of credit. As of March 31, 2026, PSE&G’s letters of credit outstanding were immaterial under this uncommitted credit facility.

| Debt and Credit Facilities | Note 9. Debt and Credit Facilities Long-Term Debt Financing Transactions The following long-term debt transactions occurred in the three months ended March 31, 2026: PSE&G • issued $500 million of 4.20% Secured Medium-Term Notes, Series R, due January 2031, • issued $500 million of 5.63% Secured Medium-Term Notes, Series R, due January 2056, and • retired $450 million of 0.95% Secured Medium-Term Notes, Series N, at maturity. Short-Term Liquidity PSEG meets its short-term liquidity requirements, as well as those of PSEG Power, primarily through the issuance of commercial paper and, from time to time, short-term loans. PSE&G maintains its own separate commercial paper program to meet its short-term liquidity requirements. Each commercial paper program is fully back-stopped by its own separate credit facility. The commitments under the $3.8 billion credit facilities are provided by a diverse bank group. As of March 31, 2026, the total available credit capacity was $3.5 billion. In March 2026, PSEG, PSEG Power, and PSE&G executed a two-year extension to their existing $3.75 billion revolving credit facilities, extending the maturity through March 2031, and removed the sustainability linked pricing mechanism associated with the PSEG sublimit of the Master Credit Facility. The $75 million PSEG Power letter of credit facility was also extended through March 2028. As of March 31, 2026, no single institution represented more than 9% of the total commitments in the credit facilities. As of March 31, 2026, PSEG’s liquidity position, including credit facilities and access to external financing, was expected to be sufficient to meet its projected stressed requirements over a 12-month planning horizon. Each of the credit facilities is restricted as to availability and use to the specific companies as listed in the following table; however, if necessary, the PSEG facilities can also be used to support its subsidiaries’ liquidity needs. The total committed credit facilities and available liquidity as of March 31, 2026 were as follows:
(A) Master Credit Facility with sub-limits of $1.5 billion for PSEG and $1.25 billion for PSEG Power; sub-limits can be adjusted pursuant to the terms of the Master Credit Facility agreement. (B) The primary use of PSEG’s and PSE&G’s credit facilities is to support their respective Commercial Paper Programs, under which as of March 31, 2026, PSEG had $165 million commercial paper outstanding at a weighted average interest rate of 4.05% and PSE&G had no commercial paper outstanding. (C) Amounts do not include uncommitted credit facilities or 364-day term loans, if any apply.

As of March 31, 2026, PSEG Power had $190 million in letters of credit outstanding under these uncommitted credit facilities. PSE&G has an uncommitted credit facility totaling $30 million, which can be utilized for letters of credit. As of March 31, 2026, PSE&G’s letters of credit outstanding were immaterial under this uncommitted credit facility. Short-Term Loans In December 2025, PSEG Power amended its existing $400 million 364-day variable rate term loan, which increased the balance to $500 million and extended the maturity to December 2026.

| Financial Risk Management Activities | Note 10. Financial Risk Management Activities Derivative accounting guidance requires that a derivative instrument be recognized as either an asset or a liability at fair value, with changes in fair value of the derivative recognized in earnings each period. Other accounting treatments are available through special election and designation provided that the derivative instrument meets specific, restrictive criteria, both at the time of designation and on an ongoing basis. These alternative permissible treatments include normal purchases and normal sales (NPNS), cash flow hedge and fair value hedge accounting. PSEG uses interest rate swaps and other derivatives, which are designated and qualifying as cash flow or fair value hedges. PSEG Power enters into additional contracts that are derivatives, but are not designated as either cash flow hedges or fair value hedges. These transactions are economic hedges and are recorded at fair market value with changes recognized in earnings. Commodity Prices Within PSEG and its affiliate companies, PSEG Power has the most exposure to commodity price risk. PSEG Power is exposed to commodity price risk primarily relating to changes in the market price of electricity, natural gas and other commodities. Fluctuations in market prices result from changes in supply and demand, fuel costs, market conditions, weather, state and federal regulatory policies, environmental policies, transmission availability and other factors. PSEG Power uses a variety of derivative and non-derivative instruments, such as financial options, futures and swaps to manage the exposure to fluctuations in commodity prices and optimize the value of PSEG Power’s expected generation. PSEG Power also uses derivatives to hedge a portion of its anticipated BGSS obligations with PSE&G. For additional information see Note 8. Commitments and Contingent Liabilities. Interest Rates PSEG, PSE&G and PSEG Power are subject to the risk of fluctuating interest rates in the normal course of business. Exposure to this risk is managed by targeting a balanced debt maturity profile which limits refinancing in any given period or interest rate environment. PSEG and PSEG Power may use a mix of fixed and floating rate debt and interest rate hedges. Cash Flow Hedges PSEG uses interest rate hedges which are designated and effective as cash flow hedges, to manage its exposure to the variability of cash flows, primarily related to variable-rate debt instruments or anticipated future long-term debt issuances. As of March 31, 2026, PSEG had interest rate hedges outstanding through December 2026 which were executed to convert to fixed, a portion of PSEG Power’s $500 million variable rate loan due December 2026. The fair value of these hedges was $1 million as of March 31, 2026. As of March 31, 2026, PSEG also had interest rate hedges outstanding to fix the interest rate for anticipated 2026 debt issuances. The fair value of these hedges was $8 million as of March, 31, 2026. The Accumulated Other Comprehensive Income (Loss) (after tax) related to outstanding and terminated interest rate hedges designated as cash flow hedges was $27 million and $24 million as of March 31, 2026 and December 31, 2025, respectively. The after-tax unrealized gains on these hedges expected to be reclassified to earnings during the next 12 months are $4 million. Fair Values of Derivative Instruments The following are the fair values of derivative instruments on the Condensed Consolidated Balance Sheets. The following tables also include disclosures for offsetting derivative assets and liabilities which are subject to a master netting or similar agreement. In general, the terms of the agreements provide that in the event of an early termination the counterparties have the right to offset amounts owed or owing under that and any other agreement with the same counterparty. Accordingly, and in accordance with PSEG’s accounting policy, these positions are offset on the Condensed Consolidated Balance Sheets of PSEG. For additional information see Note 11. Fair Value Measurements. Substantially all derivative instruments are contracts subject to master netting agreements. Contracts not subject to master netting or similar agreements are immaterial and did not have any collateral posted or received as of March 31, 2026 and December 31, 2025. The following tabular disclosure does not include the offsetting of trade receivables and payables.
(A) Represents the netting of fair value balances with the same counterparty (where the right of offset exists) and the application of cash collateral. All cash collateral (received) posted that has been allocated to derivative positions, where the right of offset exists, has been offset on the Condensed Consolidated Balance Sheets. As of March 31, 2026 and December 31, 2025, PSEG Power had net cash collateral (receipts) payments to counterparties of $221 million and $222 million, respectively. Of these net cash collateral (receipts) payments, $96 million as of March 31, 2026 and $99 million as of December 31, 2025 were netted against the corresponding net derivative contract positions. Of the $96 million as of March 31, 2026, $(2) million was netted against noncurrent assets, $82 million was netted against current liabilities and $16 million against noncurrent liabilities. Of the $99 million as of December 31, 2025, $14 million was netted against current liabilities and $85 million against noncurrent liabilities. Certain of PSEG Power’s derivative instruments contain provisions that require PSEG Power to post collateral. This collateral may be posted in the form of cash or credit support with thresholds contingent upon PSEG Power’s credit rating from each of the major credit rating agencies. The collateral and credit support requirements vary by contract and by counterparty. These credit risk-related contingent features stipulate that if PSEG Power were to be downgraded to a below investment grade rating by S&P or Moody’s, it would be required to provide additional collateral. A below investment grade credit rating for PSEG Power would represent a two level downgrade from its current Moody’s and S&P ratings. This incremental collateral requirement can offset collateral requirements related to other derivative instruments that are assets with the same counterparty, where the contractual right of offset exists under applicable master agreements. PSEG Power may also enter into commodity transactions on the New York Mercantile Exchange (NYMEX), Nodal Exchange (Nodal) and Intercontinental Exchange (ICE). The NYMEX, Nodal and ICE clearing houses act as counterparties to each trade. Transactions on the NYMEX, Nodal and ICE must adhere to comprehensive collateral and margin requirements. The aggregate fair value of all derivative instruments with credit risk-related contingent features in a liability position that are not fully collateralized (excluding transactions on the NYMEX, Nodal and ICE that are fully collateralized) was $146 million as of March 31, 2026 and $96 million as of December 31, 2025. As of March 31, 2026 and December 31, 2025, PSEG Power had the contractual right of offset of $20 million and $11 million, respectively, related to derivative instruments that are assets with the same counterparty under master agreements and net of margin posted. If PSEG Power had been downgraded to a below investment grade rating, it would have had additional collateral obligations of $126 million and $85 million as of March 31, 2026 and December 31, 2025, respectively, related to its derivatives, net of the contractual right of offset under master agreements and the application of collateral. The following shows the effect on the Condensed Consolidated Statements of Operations and on AOCL of derivative instruments designated as cash flow hedges for the three months ended March 31, 2026 and 2025:
The effect of interest rate cash flow hedges is recorded in Interest Expense in PSEG’s Condensed Consolidated Statement of Operations. For the three months ended March 31, 2026 and 2025, the amount of gain on interest rate hedges reclassified from AOCL into income was $1 million and after-tax, respectively. The following reconciles the Accumulated Other Comprehensive Income (Loss) for derivative activity included in the AOCL of PSEG on a pre-tax and after-tax basis.
The following shows the effect on the Condensed Consolidated Statements of Operations of derivative instruments not designated as hedging instruments or as NPNS for the three months ended March 31, 2026 and 2025, respectively. PSEG Power’s derivative contracts reflected in this table primarily includes contracts to hedge the purchase and sale of electricity and natural gas.
The following table summarizes the net notional volume purchases/(sales) of open derivative transactions by commodity as of March 31, 2026 and December 31, 2025.
Commodity Credit Risk Credit risk relates to the risk of loss that PSEG would incur as a result of non-performance by counterparties pursuant to the terms of their contractual obligations for the purchase and/or sale of energy, nuclear fuel and other related products. PSEG has established credit policies that it believes significantly minimize credit risk. These policies include an evaluation of potential counterparties’ financial condition (including credit rating), collateral requirements under certain circumstances and the use of standardized agreements, which allow for the netting of positive and negative exposures associated with a single counterparty. In the event of non-performance or non-payment by a major counterparty, there may be a material adverse impact on PSEG’s financial condition, results of operations or net cash flows. As of March 31, 2026, more than 98% of the net credit exposure for PSEG Power’s wholesale operations was with investment grade counterparties. There was one counterparty with credit exposure greater than 10% of the total. This credit exposure was with PSE&G. The PSE&G credit exposure is eliminated in consolidation. See Note 17. Related-Party Transactions for additional information. PSE&G’s supplier master agreements are approved by the BPU and govern the terms of its electric supply procurement contracts. These agreements define a supplier’s performance assurance requirements and allow a supplier to meet its credit requirements with a certain amount of unsecured credit. The amount of unsecured credit is determined based on the supplier’s credit ratings from the major credit rating agencies and the supplier’s tangible net worth. The credit position is based on the initial market price, which is the forward price of energy on the day the procurement transaction is executed, compared to the forward price curve for energy on the valuation day. To the extent that the forward price curve for energy exceeds the initial market price, the supplier is required to post a parental guarantee or other security instrument such as a letter of credit or cash, as collateral to the extent the credit exposure is greater than the supplier’s unsecured credit limit. As of March 31, 2026, PSE&G held parental guarantees, letters of credit and cash as security. PSE&G’s BGS suppliers’ credit exposure is calculated each business day. As of March 31, 2026, PSE&G had $118 million in unsecured mark-to-market credit exposure with its suppliers. PSE&G is permitted to recover its costs of procuring energy through the BPU-approved BGS tariffs. PSE&G’s counterparty credit risk is mitigated by its ability to recover realized energy costs through customer rates. |

| Fair Value Measurements | Note 11. Fair Value Measurements Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Accounting guidance for fair value measurement emphasizes that fair value is a market-based measurement, not an entity-specific measurement, and establishes a fair value hierarchy that distinguishes between assumptions based on market data obtained from independent sources and those based on an entity’s own assumptions. The hierarchy prioritizes the inputs to fair value measurement into three levels: Level 1—measurements utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that PSEG and PSE&G have the ability to access. These consist primarily of listed equity securities and money market mutual funds, as well as natural gas and electric futures contracts executed on an exchange. Level 2—measurements include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and other observable inputs such as interest rates and yield curves that are observable at commonly quoted intervals. These consist primarily of non-exchange traded derivatives such as futures or forward contracts, all option contracts and most fixed income securities. Level 3—measurements use unobservable inputs for assets or liabilities, based on the best information available and might include an entity’s own data and assumptions. In some valuations, the inputs used may fall into different levels of the hierarchy. In these cases, the financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. These consist primarily of certain capacity contracts that deliver beyond the PJM capacity auction periods. Certain derivative transactions may transfer from Level 2 to Level 3 if inputs become unobservable and internal modeling techniques are employed to determine fair value. Conversely, measurements may transfer from Level 3 to Level 2 if the inputs become observable. There were no transfers to or from Level 3 during the three months ended March 31, 2026 and 2025, respectively. The following tables present information about PSEG’s and PSE&G’s respective assets and (liabilities) measured at fair value on a recurring basis as of March 31, 2026 and December 31, 2025, including the fair value measurements and the levels of inputs used in determining those fair values. Amounts shown for PSEG include the amounts shown for PSE&G.
(A) Represents money market mutual funds. (B) Level 1—These contracts represent natural gas and electric futures contracts executed on an exchange, and are being valued solely on settled pricing inputs which come directly from the exchange such as NYMEX, ICE and Nodal Exchange. Level 2—Fair values for energy-related contracts are obtained primarily using a market-based approach. Most derivative contracts (forward purchase or sale contracts, futures, swaps and all options) are valued using settled prices from similar assets and liabilities from an exchange, such as NYMEX, ICE and Nodal Exchange, or auction prices. Prices used in the valuation process are also corroborated independently by management to determine that values are based on actual transaction data or, in the absence of transactions, bid and offers for the day. Examples may include certain electricity, capacity and natural gas contracts based on market prices, basis adjustments and other premiums where adjustments and premiums are not considered significant to the overall inputs. Level 3—Unobservable inputs are used for the valuation of certain contracts. See “Additional Information Regarding Level 3 Measurements” for more information on the utilization of unobservable inputs. (C) Interest rate derivatives are valued using quoted prices on commonly quoted intervals, which are interpolated for periods different than the quoted intervals, as inputs to a market valuation model. Market inputs can generally be verified and model selection does not involve significant management judgment. (D) The NDT Fund maintains investments in various equity and fixed income securities. The Rabbi Trust maintains investments in a Russell 3000 index fund and various fixed income securities. These securities are generally valued with prices that are either exchange provided (equity securities) or market transactions for comparable securities and/or broker quotes (fixed income securities). The fair value measurement table excludes any cash and foreign currency included in these trusts. For additional information, see Note 6. Trust Investments. Level 1—Investments in marketable equity securities within the NDT Fund are primarily investments in common stocks across a broad range of industries and sectors. Most equity securities are priced utilizing the principal market close price or, in some cases, midpoint, bid or ask price. Certain other securities classified as equity in the NDT and Rabbi Trust Funds consist primarily of investments in money market funds which seek a high level of current income as is consistent with the preservation of capital and the maintenance of liquidity. To pursue its goals, the funds normally invest in diversified portfolios of high quality, short-term, dollar-denominated debt securities and government securities. The funds’ net asset value is priced and published daily. The Rabbi Trust’s Russell 3000 index fund is valued based on quoted prices in an active market and can be redeemed daily without restriction. Level 2—NDT and Rabbi Trust fixed income securities include primarily investment grade corporate bonds, collateralized mortgage obligations, asset-backed securities and certain government and U.S. Treasury obligations or Federal Agency asset-backed securities and municipal bonds with a wide range of maturities. Since many fixed income securities do not trade on a daily basis, they are priced using an evaluated pricing methodology that varies by asset class and reflects observable market information such as the most recent exchange price or quoted bid for similar securities. Market-based standard inputs typically include benchmark yields, reported trades, broker/dealer quotes and issuer spreads. Certain short-term investments are valued using observable market prices or market parameters such as time-to-maturity, coupon rate, quality rating and current yield. (E) Represents the netting of fair value balances with the same counterparty (where the right of offset exists) and the application of collateral. See Note 10. Financial Risk Management Activities for additional detail. Additional Information Regarding Level 3 Measurements For valuations that include both observable and unobservable inputs, if the unobservable input is determined to be significant to the overall inputs, the entire valuation is categorized in Level 3. This includes derivatives valued using indicative price quotations for contracts with tenors that extend into periods with no observable pricing. In instances where observable data is unavailable, consideration is given to the assumptions that market participants would use in valuing the asset or liability. This includes assumptions about market risks such as liquidity, volatility and contract duration. Such instruments are categorized in Level 3 because the model inputs generally are not observable. PSEG considers credit and non-performance risk in the valuation of derivative contracts categorized in Levels 2 and 3, including both historical and current market data, in its assessment of credit and non-performance risk by counterparty. The impacts of credit and non-performance risk were not material to the financial statements. As of March 31, 2026, PSEG carried $3.3 billion of net assets that were measured at fair value on a recurring basis. No liabilities were measured using unobservable inputs and classified as Level 3 within the fair value hierarchy. As of March 31, 2025, PSEG carried $3.6 billion of net assets that were measured at fair value on a recurring basis, of which $1 million of net liabilities were measured using unobservable inputs and classified as Level 3 within the fair value hierarchy and are considered immaterial. Fair Value of Debt The estimated fair values, carrying amounts and methods used to determine the fair value of long-term debt as of March 31, 2026 and December 31, 2025 are included in the following table and accompanying notes.
(A) Given that these bonds do not trade actively, the fair value amounts of taxable debt securities (primarily Level 2 measurements) are generally determined by a valuation model using market-based measurements that are processed through a rules-based pricing methodology. The fair value amounts above do not represent the price at which the outstanding debt may be called for redemption by each issuer under their respective debt agreements. |

| Income Taxes | Note 13. Income Taxes
PSEG’s and PSE&G’s total income tax expense (benefit) for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, PSEG and PSE&G update the respective estimated annual effective tax rates, and if the estimated tax rate changes, PSEG and PSE&G make cumulative adjustments. PSEG’s effective tax rates in the three months ended March 31, 2026 and 2025 were 12.6% and 4.5%, respectively. PSE&G’s effective tax rates in the three months ended March 31, 2026 and 2025 were 12.0% and 7.5%, respectively. PSEG and PSE&G’s lower effective tax rate compared to the statutory tax rate is primarily driven by the effects of utility ratemaking. The increase in the effective tax rates for the three months ended March 31, 2026 was driven by a decrease in the flowback of historic mixed service cost deductions as an effect of utility ratemaking in 2026 compared to 2025. In August 2022, the Inflation Reduction Act (IRA) was signed into law. The IRA enacted a new 15% corporate alternative minimum tax (CAMT), which is based on adjusted financial statement income. In 2025, PSEG determined that it is subject to CAMT as it is an applicable corporation. As of March 31, 2026, PSEG and PSE&G recorded a CAMT liability of approximately $180 million and $140 million, respectively, along with corresponding deferred tax assets related to CAMT credit carryforwards, which management expects to fully utilize in future periods. However, certain CAMT rules remain unclear; therefore, the issuance of additional authoritative guidance could materially impact PSEG’s and PSE&G’s results of operations, financial condition and cash flows. The enactment of additional federal or state tax legislation and clarification of previously enacted tax laws could impact PSEG’s and PSE&G’s financial statements. |

| Financial Information By Business Segment | Note 16. Financial Information by Business Segment As discussed below, PSEG’s two reportable segments are PSE&G and PSEG Power & Other, which includes amounts related to the PSEG Power operating segment as well as amounts applicable to Energy Holdings, PSEG LI, PSEG (parent corporation) and Services, which do not meet the definition of operating segments individually or in the aggregate and are immaterial to PSEG’s consolidated assets and results. PSE&G The PSE&G reportable segment earns revenues from its tariffs, under which it provides electric transmission and electric and gas distribution services to residential, commercial and industrial customers in New Jersey. The rates charged for electric transmission are regulated by FERC while the rates charged for electric and gas distribution are regulated by the BPU. Revenues are also earned from several other activities such as investments in EE equipment on customers’ premises, solar investments, the appliance service business and other miscellaneous services. PSEG Power & Other This reportable segment is comprised primarily of PSEG Power which earns revenues primarily by selling energy and capacity from our nuclear generation units and from the sale of wholesale natural gas through a full-requirements BGSS contract with PSE&G. PSEG Power also enters into bilateral contracts for energy, gas and other energy-related contracts to optimize the value of its portfolio of generating assets and gas supply obligations. This reportable segment also includes amounts applicable to PSEG LI, which generates revenues under its contract with LIPA, primarily for the recovery of costs when Servco is a principal in the transaction (see Note 3. Variable Interest Entity for additional information) as well as fixed and variable fee components under the contract, and Energy Holdings which holds an immaterial portfolio of remaining lease investments. Other also includes amounts applicable to PSEG (parent company) and Services.
(A) PSEG Power & Other results include net after-tax gains (losses) of $(30) million and $(135) million for the three months ended March 31, 2026 and 2025, respectively, related to the impacts of non-trading commodity mark-to-market activity, which consists of the financial impact from positions with future delivery dates. (B) Intercompany eliminations primarily relate to intercompany transactions between PSE&G and PSEG Power. For a further discussion of the intercompany transactions between PSE&G and PSEG Power, see Note 2. Revenues and Note 17. Related-Party Transactions.

| Revenue from Contract with Customer [Abstract] | |
| Revenues from Contracts with Customers | PSE&G Revenues from Contracts with Customers Electric and Gas Distribution and Transmission Revenues—PSE&G sells gas and electricity to customers under default commodity supply tariffs. PSE&G’s regulated electric and gas default commodity supply and distribution services are separate tariffs which are satisfied as the product(s) and/or service(s) are delivered to the customer. The electric and gas commodity and delivery tariffs are recurring contracts in effect until modified through the regulatory approval process as appropriate. Revenue is recognized over time as the service is rendered to the customer. Included in PSE&G’s regulated revenues are unbilled electric and gas revenues which represent the estimated amount customers will be billed for services rendered from the most recent meter reading to the end of the respective accounting period. PSE&G’s transmission revenues are earned under a separate tariff using a FERC-approved annual formula rate mechanism. The performance obligation of transmission service is satisfied and revenue is recognized as it is provided to the customer. The formula rate mechanism provides for an annual filing of an estimated revenue requirement with rates effective January 1 of each year and a true-up to that estimate based on actual revenue requirements. The true-up mechanism is an alternative revenue which is outside the scope of revenue from contracts with customers. Other Revenues from Contracts with Customers Other revenues from contracts with customers, which are not a material source of PSE&G revenues, are generated primarily from appliance repair services and solar generation projects. The performance obligations under these contracts are satisfied and revenue is recognized as control of products is delivered or services are rendered. Revenues Unrelated to Contracts with Customers Other PSE&G revenues unrelated to contracts with customers are derived from alternative revenue mechanisms recorded pursuant to regulatory accounting guidance. These revenues, which include the Conservation Incentive Program (CIP), green energy program true-ups and transmission formula rate true-ups, are not a material source of PSE&G revenues. PSEG Power & Other Revenues from Contracts with Customers Electricity and Related Products—PSEG Power owns generation solely within PJM Interconnection, L.L.C. (PJM), which facilitates the dispatch of energy and energy-related products. PSEG Power primarily sells to the PJM Independent System Operator (ISO) energy and ancillary services which are separately transacted in the day-ahead or real-time energy markets. The energy and ancillary services performance obligations are typically satisfied over time as delivered and revenue is recognized accordingly. PSEG generally reports electricity sales and purchases conducted with PJM net on an hourly basis in either Operating Revenues or Energy Costs in its Condensed Consolidated Statements of Operations. The classification depends on the net hourly activity. PSEG Power enters into capacity sales and capacity purchases through PJM. The transactions are reported on a net basis dependent on PSEG Power’s monthly net sale or purchase position through PJM. The performance obligations with PJM are satisfied over time upon delivery of the capacity and revenue is recognized accordingly. In addition to capacity sold through PJM, PSEG Power sells capacity through bilateral contracts and the related revenue is reported on a gross basis and recognized over time upon delivery of the capacity. In May 2025, PSEG Power’s Salem 1, Salem 2 and Hope Creek nuclear plants zero emission certificate (ZEC) sales concluded. These nuclear plants received ZEC revenue from the electric distribution companies (EDCs) in New Jersey. PSEG Power recognized revenue when the units generated electricity, which was when the performance obligation was satisfied. These revenues have been considered variable consideration within the scope of revenue from contracts with customers and are included in PJM Sales in the following tables. ZEC revenue has been adjusted by the estimated production tax credit (PTCs) generated from these nuclear plants. ZEC revenue will be adjusted based upon the actual value of the PTCs generated by these nuclear plants and that adjustment could be material. In March 2026, the BPU issued a proposal instructing how nuclear plants should refund to the EDCs, and then how EDCs should refund to customers, the value of the ZECs generated in 2024 and purchased from the nuclear plants that were subsequently offset by PTC. Gas Contracts—PSEG Power sells wholesale natural gas, primarily through an index based full-requirements Basic Gas Supply Service (BGSS) contract with PSE&G to meet the gas supply requirements of PSE&G’s customers. The BGSS contract remains in effect unless terminated by either party with a two-year notice. Based upon the availability of natural gas, storage and pipeline capacity beyond PSE&G’s daily needs, PSEG Power also sells gas and pipeline capacity to other counterparties under bilateral contracts. The performance obligation is primarily the delivery of gas which is satisfied over time. Revenue is recognized as gas is delivered or pipeline capacity is released. PSEG LI Contract—PSEG LI has a contract with LIPA which generates revenues. PSEG LI’s subsidiary, Long Island Electric Utility Servco, LLC (Servco) records costs which are recovered from LIPA and records the recovery of those costs as revenues when Servco is a principal in the transaction. In September 2025, the LIPA board of trustees approved a five-year extension of the contract. See Amended OSA below for further information. Other Revenues from Contracts with Customers PSEG Power had contracted to provide energy management and fuel procurement services for LIPA. Revenue was recognized over time as services were rendered. This agreement expired in December 2025. Revenues Unrelated to Contracts with Customers PSEG Power’s revenues unrelated to contracts with customers include electric, gas and certain energy-related transactions accounted for in accordance with Derivatives and Hedging accounting guidance. See Note 10. Financial Risk Management Activities for further discussion. Energy Holdings generates lease revenues which are recorded pursuant to lease accounting guidance. |

| Revenue, Capacity Auction Obligations | Capacity Revenues from the PJM Annual Base Residual and Incremental Auctions—The Base Residual Auction is generally conducted annually three years in advance of the operating period. However, changes to capacity market rules have resulted in auction suspensions and delays so that recent auctions have been run closer in time to their operating periods.

PSEG Power does not intend to sell these securities, nor will it be more-likely-than-not required to sell before recovery of their amortized cost. PSEG Power did not recognize credit losses for corporate bonds because they are primarily investment grade securities. |

| Schedule of Derivative Instruments Fair Value in Balance Sheets | The following are the fair values of derivative instruments on the Condensed Consolidated Balance Sheets. The following tables also include disclosures for offsetting derivative assets and liabilities which are subject to a master netting or similar agreement. In general, the terms of the agreements provide that in the event of an early termination the counterparties have the right to offset amounts owed or owing under that and any other agreement with the same counterparty. Accordingly, and in accordance with PSEG’s accounting policy, these positions are offset on the Condensed Consolidated Balance Sheets of PSEG. For additional information see Note 11. Fair Value Measurements. Substantially all derivative instruments are contracts subject to master netting agreements. Contracts not subject to master netting or similar agreements are immaterial and did not have any collateral posted or received as of March 31, 2026 and December 31, 2025. The following tabular disclosure does not include the offsetting of trade receivables and payables.
(A)
Represents the netting of fair value balances with the same counterparty (where the right of offset exists) and the application of cash collateral. All cash collateral (received) posted that has been allocated to derivative positions, where the right of offset exists, has been offset on the Condensed Consolidated Balance Sheets. As of March 31, 2026 and December 31, 2025, PSEG Power had net cash collateral (receipts) payments to counterparties of $221 million and $222 million, respectively. Of these net cash collateral (receipts) payments, $96 million as of March 31, 2026 and $99 million as of December 31, 2025 were netted against the corresponding net derivative contract positions. Of the $96 million as of March 31, 2026, $(2) million was netted against noncurrent assets, $82 million was netted against current liabilities and $16 million against noncurrent liabilities. Of the $99 million as of December 31, 2025, $14 million was netted against current liabilities and $85 million against noncurrent liabilities. |

| PSEG's and PSE&G's Respective Assets and (Liabilities) Measured at Fair Value on a Recurring Basis | The following tables present information about PSEG’s and PSE&G’s respective assets and (liabilities) measured at fair value on a recurring basis as of March 31, 2026 and December 31, 2025, including the fair value measurements and the levels of inputs used in determining those fair values. Amounts shown for PSEG include the amounts shown for PSE&G.
(A) Represents money market mutual funds. (B) Level 1—These contracts represent natural gas and electric futures contracts executed on an exchange, and are being valued solely on settled pricing inputs which come directly from the exchange such as NYMEX, ICE and Nodal Exchange. Level 2—Fair values for energy-related contracts are obtained primarily using a market-based approach. Most derivative contracts (forward purchase or sale contracts, futures, swaps and all options) are valued using settled prices from similar assets and liabilities from an exchange, such as NYMEX, ICE and Nodal Exchange, or auction prices. Prices used in the valuation process are also corroborated independently by management to determine that values are based on actual transaction data or, in the absence of transactions, bid and offers for the day. Examples may include certain electricity, capacity and natural gas contracts based on market prices, basis adjustments and other premiums where adjustments and premiums are not considered significant to the overall inputs. Level 3—Unobservable inputs are used for the valuation of certain contracts. See “Additional Information Regarding Level 3 Measurements” for more information on the utilization of unobservable inputs. (C) Interest rate derivatives are valued using quoted prices on commonly quoted intervals, which are interpolated for periods different than the quoted intervals, as inputs to a market valuation model. Market inputs can generally be verified and model selection does not involve significant management judgment. (D) The NDT Fund maintains investments in various equity and fixed income securities. The Rabbi Trust maintains investments in a Russell 3000 index fund and various fixed income securities. These securities are generally valued with prices that are either exchange provided (equity securities) or market transactions for comparable securities and/or broker quotes (fixed income securities). The fair value measurement table excludes any cash and foreign currency included in these trusts. For additional information, see Note 6. Trust Investments. Level 1—Investments in marketable equity securities within the NDT Fund are primarily investments in common stocks across a broad range of industries and sectors. Most equity securities are priced utilizing the principal market close price or, in some cases, midpoint, bid or ask price. Certain other securities classified as equity in the NDT and Rabbi Trust Funds consist primarily of investments in money market funds which seek a high level of current income as is consistent with the preservation of capital and the maintenance of liquidity. To pursue its goals, the funds normally invest in diversified portfolios of high quality, short-term, dollar-denominated debt securities and government securities. The funds’ net asset value is priced and published daily. The Rabbi Trust’s Russell 3000 index fund is valued based on quoted prices in an active market and can be redeemed daily without restriction. Level 2—NDT and Rabbi Trust fixed income securities include primarily investment grade corporate bonds, collateralized mortgage obligations, asset-backed securities and certain government and U.S. Treasury obligations or Federal Agency asset-backed securities and municipal bonds with a wide range of maturities. Since many fixed income securities do not trade on a daily basis, they are priced using an evaluated pricing methodology that varies by asset class and reflects observable market information such as the most recent exchange price or quoted bid for similar securities. Market-based standard inputs typically include benchmark yields, reported trades, broker/dealer quotes and issuer spreads. Certain short-term investments are valued using observable market prices or market parameters such as time-to-maturity, coupon rate, quality rating and current yield. (E)
