Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory authorities, and governmental agencies in the ordinary course of business.  While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition, except as otherwise discussed in the Form 10-K or in this report.  Entergy discusses regulatory proceedings in Note 2 to the financial statements in the Form 10-K and herein and discusses tax proceedings in Note 3 to the financial statements in the Form 10-K and Note 10 to the financial statements herein.

Spent Nuclear Fuel Litigation

See Note 8 to the financial statements in the Form 10-K for information on Entergy’s spent nuclear fuel litigation. The following is an update to that discussion.

As discussed in the Form 10-K, in October 2024 the U.S. Court of Federal Claims issued a final judgment in the amount of $7 million in favor of Holtec Palisades, LLC (previously Entergy Nuclear Palisades) and against the DOE in the final round Palisades damages case. Holtec, as the current owner, received payment from the U.S. Treasury in March 2025 and subsequently transferred the $7 million judgment to Entergy. The effect in 2024 of recording the judgment was a reduction to asset write-offs, impairments, and related charges (credits). The damages awarded included $4 million related to costs previously recorded as plant and $3 million related to costs previously recorded as other operation and maintenance expenses.

Exclusivity Agreement with Major Vendor

Entergy entered into an exclusivity agreement with a major vendor to manufacture power island equipment (PIE) and combustion turbines (CT) for combustion turbine generator set frames larger than 400 MWs. The agreement guarantees Entergy one manufacturing slot per quarter for the shorter of a five-year period or until Entergy fulfills its minimum commitment. The agreement commits Entergy to a minimum order of 15 sets of PIE and two CTs during that time period. The commitments are fully transferable to any of the Utility operating companies, including those not listed below. The aggregate minimum commitment as allocated by unit among the Utility operating companies is as follows:
PIE
CT
Entergy Arkansas41
Entergy Louisiana9—
Entergy Mississippi2—
Entergy Texas—1
Total152

Cancellation or failure to purchase the minimum commitment amounts will result in a charge that will be allocated to the Utility operating company, or companies, that fell short of their original commitment amount. If any of the Utility operating companies included above purchases any PIEs or CTs within the scope of the agreement from another supplier (except as permitted under the agreement), then the vendor has the right to terminate the agreement with respect to such Utility operating company. The Utility operating company would then be obligated to pay 50% of the base price for each PIE or CT not yet ordered.

The agreement does not establish final pricing and delivery dates of purchases that will go towards meeting the commitments under the agreement. Such terms shall be agreed to in separate agreements.

Exclusivity Agreement with Major Vendor

Entergy entered into an exclusivity agreement with a major vendor to manufacture power island equipment (PIE) and combustion turbines (CT) for combustion turbine generator set frames larger than 400 MWs. The agreement guarantees Entergy one manufacturing slot per quarter for the shorter of a five-year period or until Entergy fulfills its minimum commitment. The agreement commits Entergy to a minimum order of 15 sets of PIE and two CTs during that time period. The commitments are fully transferable to any of the Utility operating companies, including those not listed below. The aggregate minimum commitment as allocated by unit among the Utility operating companies is as follows:
PIE
CT
Entergy Arkansas41
Entergy Louisiana9—
Entergy Mississippi2—
Entergy Texas—1
Total152

Cancellation or failure to purchase the minimum commitment amounts will result in a charge that will be allocated to the Utility operating company, or companies, that fell short of their original commitment amount. If any of the Utility operating companies included above purchases any PIEs or CTs within the scope of the agreement from another supplier (except as permitted under the agreement), then the vendor has the right to terminate the agreement with respect to such Utility operating company. The Utility operating company would then be obligated to pay 50% of the base price for each PIE or CT not yet ordered.

The agreement does not establish final pricing and delivery dates of purchases that will go towards meeting the commitments under the agreement. Such terms shall be agreed to in separate agreements.

Fuel and purchased power cost recovery

Entergy Arkansas

Energy Cost Recovery Rider

In March 2025, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00882 per kWh to $0.01333 per kWh. The annual redetermination included a credit related to the remaining balance due to retail customers from the System Energy settlement with the APSC, plus carrying charges and interest. See “Retail Rate Proceedings - Filings with the APSC (Entergy Arkansas) - Retail Rates - Grand Gulf Credit Rider” below for further discussion. The primary reason for the rate increase is an adjustment to account for projected increases in natural gas prices in 2025. This adjustment is expected to reduce the rate change that will be reflected in its 2026 energy cost rate redetermination. The redetermined rate of $0.01333 per kWh became effective with the first billing cycle in April 2025 through the normal operation of the tariff.

Entergy Louisiana

As discussed in the Form 10-K, in January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. In April 2025 the LPSC staff issued its audit report (for Entergy Louisiana’s gas operations), which included several prospective recommendations but no financial disallowances. The next procedural step is for the LPSC to review the report; however there is no deadline for completion of the LPSC’s review.

Retail Rate Proceedings

Filings with the APSC (Entergy Arkansas)

Retail Rates

Grand Gulf Credit Rider

As discussed in the Form 10-K, in June 2024, Entergy Arkansas filed with the APSC a tariff to provide retail customers a credit resulting from the terms of the settlement agreement between Entergy Arkansas, System Energy, additional named Entergy parties, and the APSC pertaining to System Energy’s billings for wholesale sales of energy and capacity from the Grand Gulf nuclear plant. See “Complaints Against System Energy - System Energy Settlement with the APSC” in Note 2 to the financial statements in the Form 10-K for discussion of the System Energy settlement with the APSC. In July 2024 the APSC approved the tariff, under which Entergy Arkansas would refund to retail customers a total of $100.6 million. Entergy Arkansas refunded $92.3 million of
the total through one-time bill credits under the Grand Gulf credit rider during the August 2024 billing cycle. In March 2025, Entergy Arkansas included the remaining balance as a credit to retail customers in its energy cost recovery rider rate redetermination filing. See further discussion within "Regulatory Assets and Regulatory Liabilities - Fuel and purchased power cost recovery - Entergy Arkansas - Energy Cost Recovery Rider" above. In April 2025 the APSC approved Entergy Arkansas’s proposal to include the remaining balance in its energy cost recovery rider effective with the first billing cycle of April 2025 and the withdrawal of the Grand Gulf credit rider after all credits have been issued.

Filings with the LPSC (Entergy Louisiana)

Retail Rates - Electric

2023 Formula Rate Plan Filing

As discussed in the Form 10-K, in August 2024, pursuant to the global stipulated settlement agreement, Entergy Louisiana filed its formula rate plan evaluation report for its 2023 calendar year operations. Consistent with the global stipulated settlement agreement, the filing reflected a 9.7% allowed return on common equity with a bandwidth of 40 basis points above and below the midpoint. For the 2023 test year, however, the bandwidth provisions of the formula rate plan are temporarily suspended and, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana implemented the September 2024 formula rate plan rate adjustments effective with the first billing cycle of September 2024. In January 2025, Entergy Louisiana and the LPSC filed a joint report indicating that no disputed issues remained in the proceeding and requesting that the LPSC issue an order accepting Entergy Louisiana’s evaluation report and, ultimately, resolving this matter. In March 2025 the LPSC issued an order accepting the evaluation report.

In December 2024, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed an interim rate adjustment for the 2023 test year reflecting the return of $25.1 million of refunds from the System Energy settlement with the LPSC to customers from January through August 2025. In February 2025, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting the divestiture of Entergy Louisiana’s share of Grand Gulf capacity and energy, which was effective as of January 1, 2025. The second interim rate adjustment also reflected a revenue increase of $17.8 million for the recovery of Hurricane Francine costs as approved by the LPSC (on an interim basis). The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the Hurricane Francine proceeding in “Storm Cost Recovery Filings with Retail Regulators – Entergy Louisiana – Hurricane Francine” below. See Note 8 to the financial statements in the Form 10-K for discussion of Entergy Louisiana’s divestiture from the Unit Power Sales Agreement.

Additional Generation and Transmission Resources

As discussed in the Form 10-K, in October 2024, Entergy Louisiana filed an application with the LPSC seeking approval of a variety of generation and transmission resources proposed in connection with establishing service to a new data center to be developed by a subsidiary of Meta Platforms, Inc. in north Louisiana, for which an electric service agreement has been executed. The filing requests LPSC certification of three new combined cycle combustion turbine generation resources totaling 2,262 MW, each of which will be enabled for future carbon capture and storage, a new 500 kV transmission line, and 500 kV substation upgrades. The application also requests approval to implement a corporate sustainability rider applicable to the new customer. The corporate sustainability rider contemplates the new customer contributing to the costs of the future addition of 1,500 MW of new solar and energy storage resources, agreements involving carbon capture and storage at Entergy Louisiana’s existing Lake Charles Power Station, and potential future wind and nuclear resources. Entergy Louisiana anticipates funding the incremental cost to serve the customer through direct financial contributions from the customer and the revenues it expects to earn under the electric service agreement. The electric service agreement also contains provisions for termination payments that will help ensure that there is no harm to Entergy Louisiana and its customers in the event
of early termination. A directive was issued at the LPSC’s November 2024 meeting for the matter to be decided by October 2025. In February 2025 intervenors filed a motion asking the LPSC to deny Entergy Louisiana’s requested exemption from the LPSC’s order addressing competitive solicitation procedures and further asking the LPSC to dismiss the application. The ALJ issued an order denying the motion to dismiss the application and deferring the LPSC’s consideration of the motion regarding the competitive solicitation procedures until the hearing. In March 2025 the same intervenors filed a motion requesting the LPSC to require the customer and its parent company to be joined as parties to the proceeding or dismiss the application. In April 2025 the ALJ issued an order denying the March 2025 motion, and the moving parties filed a motion asking the LPSC to review and reverse the ALJ’s decision. In April 2025 the LPSC staff and intervenors filed direct testimony. The LPSC staff’s testimony discusses the significant projected benefits associated with the data center project and also recommends that the LPSC impose certain conditions on its approval, including a condition that would require, under specified circumstances, certain sharing of net revenues from service to the project with Entergy Louisiana’s other customers. The LPSC staff also recommends that the LPSC deny approval of the corporate sustainability rider terms providing for the customer to supply funding toward the cost of installing carbon capture and storage infrastructure at Entergy Louisiana’s Lake Charles Power Station. The Louisiana Energy Users Group and other intervenors recommended that the LPSC require various changes to the terms of the electric service agreement with the customer that would shift additional risk and cost to the customer rather than Entergy Louisiana’s broader customer base. Certain intervenors also challenged approval on the basis that Entergy Louisiana did not conduct a request for proposals to procure the proposed generation resources to serve the customer’s project; these intervenors also advocate that Entergy Louisiana be required to procure more renewable generation and evaluate transmission alternatives rather than proceeding with development of all of the proposed new generation resources. Entergy Louisiana’s rebuttal testimony is due in May 2025, and a hearing is set for July 2025.

Filings with the MPSC (Entergy Mississippi)

Retail Rates

2025 Formula Rate Plan Filing

In February 2025, Entergy Mississippi submitted its formula rate plan 2025 test year filing and 2024 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2024 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2025 calendar year to also be within the formula rate plan bandwidth. The 2025 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2024 look-back filing compared actual 2024 results to the approved benchmark return on rate base and reflected no change in formula rate plan revenues, although Entergy Mississippi proposes to adjust interim rates by $135 thousand to reflect two outside-the-bandwidth changes: (1) the completion of Entergy Mississippi’s return to customers of credits under its restructuring credit rider; and (2) a true-up of demand side management costs. A final order is expected in second quarter 2025.

Interim Facilities Rate Adjustments

In May 2024, Entergy Mississippi received approval from the MPSC for formula rate plan revisions that were necessary for Entergy Mississippi to comply with state legislation passed in January 2024. The legislation allows Entergy Mississippi to make interim rate adjustments to recover the non-fuel related annual ownership cost of certain facilities that directly or indirectly provide service to customers who own certain data processing center projects as specified in the legislation. Entergy Mississippi filed the first of its annual interim facilities rate adjustment reports in May 2024 to recover approximately $8.7 million of these costs over a six-month period with rates effective beginning in July 2024. Entergy Mississippi filed its second interim facilities rate adjustment report in November 2024 to recover approximately $46.7 million of these costs over a 12-month period with rates effective beginning in January 2025. In February 2025, Entergy Mississippi filed a true-up interim facilities rate adjustment report to the initial annual interim facilities rate adjustment report filed in May 2024, reflecting the recovery of an
additional approximately $1.0 million of costs over a 12-month period with rates effective with the first billing cycle of April 2025.

Filings with the City Council (Entergy New Orleans)

Retail Rates

2025 Formula Rate Plan Filing

In April 2025, Entergy New Orleans submitted to the City Council its formula rate plan 2024 test year filing. The 2024 evaluation report produced an electric earned return on equity of 10.98% and a gas earned return on equity of 8.96% compared to the authorized return on equity for each of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million and no change in gas rates. The decrease in electric rates is driven by the realignment of regulatory liabilities into the formula from a separate rate mechanism, partially offset by the cost of known and measurable electric capital additions. The filing also commences the previously authorized recovery of certain regulatory costs and requests a revenue-neutral recovery to offset a proposed reduction in bill payment late fees. Taking into account these proposed adjustments, the filing presents a decrease in authorized electric revenues of $8.6 million and an increase in authorized gas revenues of $0.5 million. The filing is subject to a 75-day review period, followed by a 25-day period to resolve any disputes among the parties. For any disputed rate adjustments, however, the City Council would set a procedural schedule to resolve. Resulting rates will be effective with the first billing cycle of September 2025 pursuant to the formula rate plan tariff.

Filings with the PUCT and Texas Cities (Entergy Texas)

Retail Rates

Distribution Cost Recovery Factor (DCRF) Rider

In April 2025, Entergy Texas filed with the PUCT a request to amend its DCRF rider. The proposed rider is designed to collect from Entergy Texas’s retail customers approximately $77.8 million annually, or $29.3 million in incremental annual revenues beyond Entergy Texas’s currently effective DCRF rider based on its capital invested in distribution between July 1, 2024 and December 31, 2024, including distribution-related restoration costs associated with Hurricane Beryl.

Transmission Cost Recovery Factor (TCRF) Rider

As discussed in the Form 10-K, in October 2024, Entergy Texas filed with the PUCT a request to amend its TCRF rider, which was previously reset to zero in June 2023 as a result of the 2022 base rate case. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $9.7 million annually based on its capital invested in transmission between January 1, 2022 and June 30, 2024 and changes in other transmission charges. In April 2025 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 7, 2025.

Entergy Arkansas Opportunity Sales Proceeding

As discussed in the Form 10-K, in September 2020, Entergy Arkansas filed a complaint in the U.S. District Court for the Eastern District of Arkansas challenging the APSC’s denial of recovery of $135 million of payments to other Utility operating companies in December 2018 relating to off-system sales of electricity from 2002-2009, as ordered by the FERC. The complaint also involved a challenge to the $13.7 million, plus interest, of related refunds ordered by the APSC and paid by Entergy Arkansas in August 2020. The trial was held in February 2023.
In March 2024 the U.S. District Court for the Eastern District of Arkansas issued a judgment in favor of the APSC and against Entergy Arkansas. In March 2024 Entergy Arkansas filed a notice of appeal and a motion to expedite oral arguments with the United States Court of Appeals for the Eighth Circuit and the court granted the motion to expedite. As a result of the adverse decision by the U.S. District Court for the Eastern District of Arkansas, Entergy Arkansas concluded that it could no longer support the recognition of its $131.8 million regulatory asset reflecting the previously-expected recovery of a portion of the costs at issue in the opportunity sales proceeding and recorded a $131.8 million ($99.1 million net-of-tax) charge to earnings in first quarter 2024. In December 2024 the United States Court of Appeals for the Eighth Circuit affirmed the decision of the U.S. District Court for the Eastern District of Arkansas, and Entergy Arkansas filed a petition for rehearing en banc. In January 2025 the United States Court of Appeals for the Eighth Circuit denied Entergy Arkansas’s petition. In April 2025, Entergy Arkansas filed a petition for certiorari with the United States Supreme Court.

MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding

See Note 2 to the financial statements in the Form 10-K for discussion of the MSS-4 replacement tariff net operating loss carryforward proceeding.

The MSS-4 replacement tariff, a tariff governing the sales of energy and capacity among the Utility operating companies, includes protocols that provide for the disclosure of cost inputs, an opportunity for informal discovery procedures, and a challenge process. In April 2025, pursuant to such protocols, the City Council filed with the FERC a formal challenge relating to Entergy Services’ inclusion and allocation of net operating loss carryforward accumulated deferred income taxes in the MSS-4 replacement tariff rates charged to Entergy New Orleans’s monthly bills for calendar year 2023. Entergy Services plans to file a response to the formal challenge by the May 2025 deadline.

Complaints Against System Energy

See Note 2 to the financial statements in the Form 10-K for information regarding pending complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. The following is an update to that discussion.

Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue

As discussed in the Form 10-K, in February 2023, System Energy submitted a tariff compliance filing with the FERC to clarify that, consistent with the releases provided in the June 2022 MPSC settlement, Entergy Mississippi would continue to be charged for its allocation of the sale-leaseback renewal costs under the Unit Power Sales Agreement. In March 2023 the MPSC filed a protest to System Energy’s tariff compliance filing. The MPSC argued that the settlement did not specifically address post-settlement sale-leaseback renewal costs and that the sale-leaseback renewal costs may not be recovered under the Unit Power Sales Agreement. In February 2025, System Energy and the MPSC resolved their dispute concerning the sale-leaseback renewal costs. As a result, the MPSC withdrew its protest at the FERC on System Energy’s tariff compliance filing. Entergy Mississippi will continue to pay the allocated sale-leaseback renewal costs of approximately $5.7 million annually and there are no refunds due for prior periods. In March 2025, System Energy filed a status report with the FERC explaining that the dispute is resolved.
Storm Cost Recovery Filings with Retail Regulators

See Note 2 to the financial statements in the Form 10-K for discussion regarding storm cost recovery filings. The following is an update to that discussion.

Entergy Louisiana

Hurricane Francine

In September 2024, Hurricane Francine caused damage to the areas served by Entergy Louisiana. The storm resulted in widespread power outages, primarily due to damage to distribution infrastructure as a result of strong winds and heavy rain, and the loss of sales during the power outages.

In December 2024, and subsequently amended in an errata filed in February 2025, Entergy Louisiana submitted an application to the LPSC seeking a determination that approximately $183.6 million in storm restoration costs associated with Hurricane Francine were reasonable and necessary and, therefore, eligible for recovery from customers, as well as approval to recover approximately $3.6 million in certain carrying costs from customers. In February 2025, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting a revenue increase of $17.8 million from funds approved by the LPSC (on an interim basis) for Hurricane Francine recovery costs. The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the 2023 formula rate plan filing above. Also in February 2025, Entergy Louisiana withdrew $33.5 million from its funded storm reserves. In March 2025 a status conference was held in which a procedural schedule was established including a hearing in November 2025.

Fuel and purchased power cost recovery

Entergy Arkansas

Energy Cost Recovery Rider

In March 2025, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00882 per kWh to $0.01333 per kWh. The annual redetermination included a credit related to the remaining balance due to retail customers from the System Energy settlement with the APSC, plus carrying charges and interest. See “Retail Rate Proceedings - Filings with the APSC (Entergy Arkansas) - Retail Rates - Grand Gulf Credit Rider” below for further discussion. The primary reason for the rate increase is an adjustment to account for projected increases in natural gas prices in 2025. This adjustment is expected to reduce the rate change that will be reflected in its 2026 energy cost rate redetermination. The redetermined rate of $0.01333 per kWh became effective with the first billing cycle in April 2025 through the normal operation of the tariff.

Entergy Louisiana

As discussed in the Form 10-K, in January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. In April 2025 the LPSC staff issued its audit report (for Entergy Louisiana’s gas operations), which included several prospective recommendations but no financial disallowances. The next procedural step is for the LPSC to review the report; however there is no deadline for completion of the LPSC’s review.

Retail Rate Proceedings

See Note 2 to the financial statements in the Form 10-K for information regarding retail rate proceedings involving the Utility operating companies. The following are updates to that discussion.

Filings with the APSC (Entergy Arkansas)

Retail Rates

Grand Gulf Credit Rider

As discussed in the Form 10-K, in June 2024, Entergy Arkansas filed with the APSC a tariff to provide retail customers a credit resulting from the terms of the settlement agreement between Entergy Arkansas, System Energy, additional named Entergy parties, and the APSC pertaining to System Energy’s billings for wholesale sales of energy and capacity from the Grand Gulf nuclear plant. See “Complaints Against System Energy - System Energy Settlement with the APSC” in Note 2 to the financial statements in the Form 10-K for discussion of the System Energy settlement with the APSC. In July 2024 the APSC approved the tariff, under which Entergy Arkansas would refund to retail customers a total of $100.6 million. Entergy Arkansas refunded $92.3 million of
the total through one-time bill credits under the Grand Gulf credit rider during the August 2024 billing cycle. In March 2025, Entergy Arkansas included the remaining balance as a credit to retail customers in its energy cost recovery rider rate redetermination filing. See further discussion within "Regulatory Assets and Regulatory Liabilities - Fuel and purchased power cost recovery - Entergy Arkansas - Energy Cost Recovery Rider" above. In April 2025 the APSC approved Entergy Arkansas’s proposal to include the remaining balance in its energy cost recovery rider effective with the first billing cycle of April 2025 and the withdrawal of the Grand Gulf credit rider after all credits have been issued.

Filings with the LPSC (Entergy Louisiana)

Retail Rates - Electric

2023 Formula Rate Plan Filing

As discussed in the Form 10-K, in August 2024, pursuant to the global stipulated settlement agreement, Entergy Louisiana filed its formula rate plan evaluation report for its 2023 calendar year operations. Consistent with the global stipulated settlement agreement, the filing reflected a 9.7% allowed return on common equity with a bandwidth of 40 basis points above and below the midpoint. For the 2023 test year, however, the bandwidth provisions of the formula rate plan are temporarily suspended and, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana implemented the September 2024 formula rate plan rate adjustments effective with the first billing cycle of September 2024. In January 2025, Entergy Louisiana and the LPSC filed a joint report indicating that no disputed issues remained in the proceeding and requesting that the LPSC issue an order accepting Entergy Louisiana’s evaluation report and, ultimately, resolving this matter. In March 2025 the LPSC issued an order accepting the evaluation report.

In December 2024, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed an interim rate adjustment for the 2023 test year reflecting the return of $25.1 million of refunds from the System Energy settlement with the LPSC to customers from January through August 2025. In February 2025, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting the divestiture of Entergy Louisiana’s share of Grand Gulf capacity and energy, which was effective as of January 1, 2025. The second interim rate adjustment also reflected a revenue increase of $17.8 million for the recovery of Hurricane Francine costs as approved by the LPSC (on an interim basis). The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the Hurricane Francine proceeding in “Storm Cost Recovery Filings with Retail Regulators – Entergy Louisiana – Hurricane Francine” below. See Note 8 to the financial statements in the Form 10-K for discussion of Entergy Louisiana’s divestiture from the Unit Power Sales Agreement.

Additional Generation and Transmission Resources

As discussed in the Form 10-K, in October 2024, Entergy Louisiana filed an application with the LPSC seeking approval of a variety of generation and transmission resources proposed in connection with establishing service to a new data center to be developed by a subsidiary of Meta Platforms, Inc. in north Louisiana, for which an electric service agreement has been executed. The filing requests LPSC certification of three new combined cycle combustion turbine generation resources totaling 2,262 MW, each of which will be enabled for future carbon capture and storage, a new 500 kV transmission line, and 500 kV substation upgrades. The application also requests approval to implement a corporate sustainability rider applicable to the new customer. The corporate sustainability rider contemplates the new customer contributing to the costs of the future addition of 1,500 MW of new solar and energy storage resources, agreements involving carbon capture and storage at Entergy Louisiana’s existing Lake Charles Power Station, and potential future wind and nuclear resources. Entergy Louisiana anticipates funding the incremental cost to serve the customer through direct financial contributions from the customer and the revenues it expects to earn under the electric service agreement. The electric service agreement also contains provisions for termination payments that will help ensure that there is no harm to Entergy Louisiana and its customers in the event
of early termination. A directive was issued at the LPSC’s November 2024 meeting for the matter to be decided by October 2025. In February 2025 intervenors filed a motion asking the LPSC to deny Entergy Louisiana’s requested exemption from the LPSC’s order addressing competitive solicitation procedures and further asking the LPSC to dismiss the application. The ALJ issued an order denying the motion to dismiss the application and deferring the LPSC’s consideration of the motion regarding the competitive solicitation procedures until the hearing. In March 2025 the same intervenors filed a motion requesting the LPSC to require the customer and its parent company to be joined as parties to the proceeding or dismiss the application. In April 2025 the ALJ issued an order denying the March 2025 motion, and the moving parties filed a motion asking the LPSC to review and reverse the ALJ’s decision. In April 2025 the LPSC staff and intervenors filed direct testimony. The LPSC staff’s testimony discusses the significant projected benefits associated with the data center project and also recommends that the LPSC impose certain conditions on its approval, including a condition that would require, under specified circumstances, certain sharing of net revenues from service to the project with Entergy Louisiana’s other customers. The LPSC staff also recommends that the LPSC deny approval of the corporate sustainability rider terms providing for the customer to supply funding toward the cost of installing carbon capture and storage infrastructure at Entergy Louisiana’s Lake Charles Power Station. The Louisiana Energy Users Group and other intervenors recommended that the LPSC require various changes to the terms of the electric service agreement with the customer that would shift additional risk and cost to the customer rather than Entergy Louisiana’s broader customer base. Certain intervenors also challenged approval on the basis that Entergy Louisiana did not conduct a request for proposals to procure the proposed generation resources to serve the customer’s project; these intervenors also advocate that Entergy Louisiana be required to procure more renewable generation and evaluate transmission alternatives rather than proceeding with development of all of the proposed new generation resources. Entergy Louisiana’s rebuttal testimony is due in May 2025, and a hearing is set for July 2025.

Filings with the MPSC (Entergy Mississippi)

Retail Rates

2025 Formula Rate Plan Filing

In February 2025, Entergy Mississippi submitted its formula rate plan 2025 test year filing and 2024 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2024 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2025 calendar year to also be within the formula rate plan bandwidth. The 2025 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2024 look-back filing compared actual 2024 results to the approved benchmark return on rate base and reflected no change in formula rate plan revenues, although Entergy Mississippi proposes to adjust interim rates by $135 thousand to reflect two outside-the-bandwidth changes: (1) the completion of Entergy Mississippi’s return to customers of credits under its restructuring credit rider; and (2) a true-up of demand side management costs. A final order is expected in second quarter 2025.

Interim Facilities Rate Adjustments

In May 2024, Entergy Mississippi received approval from the MPSC for formula rate plan revisions that were necessary for Entergy Mississippi to comply with state legislation passed in January 2024. The legislation allows Entergy Mississippi to make interim rate adjustments to recover the non-fuel related annual ownership cost of certain facilities that directly or indirectly provide service to customers who own certain data processing center projects as specified in the legislation. Entergy Mississippi filed the first of its annual interim facilities rate adjustment reports in May 2024 to recover approximately $8.7 million of these costs over a six-month period with rates effective beginning in July 2024. Entergy Mississippi filed its second interim facilities rate adjustment report in November 2024 to recover approximately $46.7 million of these costs over a 12-month period with rates effective beginning in January 2025. In February 2025, Entergy Mississippi filed a true-up interim facilities rate adjustment report to the initial annual interim facilities rate adjustment report filed in May 2024, reflecting the recovery of an
additional approximately $1.0 million of costs over a 12-month period with rates effective with the first billing cycle of April 2025.

Filings with the City Council (Entergy New Orleans)

Retail Rates

2025 Formula Rate Plan Filing

In April 2025, Entergy New Orleans submitted to the City Council its formula rate plan 2024 test year filing. The 2024 evaluation report produced an electric earned return on equity of 10.98% and a gas earned return on equity of 8.96% compared to the authorized return on equity for each of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million and no change in gas rates. The decrease in electric rates is driven by the realignment of regulatory liabilities into the formula from a separate rate mechanism, partially offset by the cost of known and measurable electric capital additions. The filing also commences the previously authorized recovery of certain regulatory costs and requests a revenue-neutral recovery to offset a proposed reduction in bill payment late fees. Taking into account these proposed adjustments, the filing presents a decrease in authorized electric revenues of $8.6 million and an increase in authorized gas revenues of $0.5 million. The filing is subject to a 75-day review period, followed by a 25-day period to resolve any disputes among the parties. For any disputed rate adjustments, however, the City Council would set a procedural schedule to resolve. Resulting rates will be effective with the first billing cycle of September 2025 pursuant to the formula rate plan tariff.

Filings with the PUCT and Texas Cities (Entergy Texas)

Retail Rates

Distribution Cost Recovery Factor (DCRF) Rider

In April 2025, Entergy Texas filed with the PUCT a request to amend its DCRF rider. The proposed rider is designed to collect from Entergy Texas’s retail customers approximately $77.8 million annually, or $29.3 million in incremental annual revenues beyond Entergy Texas’s currently effective DCRF rider based on its capital invested in distribution between July 1, 2024 and December 31, 2024, including distribution-related restoration costs associated with Hurricane Beryl.

Transmission Cost Recovery Factor (TCRF) Rider

As discussed in the Form 10-K, in October 2024, Entergy Texas filed with the PUCT a request to amend its TCRF rider, which was previously reset to zero in June 2023 as a result of the 2022 base rate case. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $9.7 million annually based on its capital invested in transmission between January 1, 2022 and June 30, 2024 and changes in other transmission charges. In April 2025 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 7, 2025.

Entergy Arkansas Opportunity Sales Proceeding

As discussed in the Form 10-K, in September 2020, Entergy Arkansas filed a complaint in the U.S. District Court for the Eastern District of Arkansas challenging the APSC’s denial of recovery of $135 million of payments to other Utility operating companies in December 2018 relating to off-system sales of electricity from 2002-2009, as ordered by the FERC. The complaint also involved a challenge to the $13.7 million, plus interest, of related refunds ordered by the APSC and paid by Entergy Arkansas in August 2020. The trial was held in February 2023.
In March 2024 the U.S. District Court for the Eastern District of Arkansas issued a judgment in favor of the APSC and against Entergy Arkansas. In March 2024 Entergy Arkansas filed a notice of appeal and a motion to expedite oral arguments with the United States Court of Appeals for the Eighth Circuit and the court granted the motion to expedite. As a result of the adverse decision by the U.S. District Court for the Eastern District of Arkansas, Entergy Arkansas concluded that it could no longer support the recognition of its $131.8 million regulatory asset reflecting the previously-expected recovery of a portion of the costs at issue in the opportunity sales proceeding and recorded a $131.8 million ($99.1 million net-of-tax) charge to earnings in first quarter 2024. In December 2024 the United States Court of Appeals for the Eighth Circuit affirmed the decision of the U.S. District Court for the Eastern District of Arkansas, and Entergy Arkansas filed a petition for rehearing en banc. In January 2025 the United States Court of Appeals for the Eighth Circuit denied Entergy Arkansas’s petition. In April 2025, Entergy Arkansas filed a petition for certiorari with the United States Supreme Court.

Complaints Against System Energy

See Note 2 to the financial statements in the Form 10-K for information regarding pending complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. The following is an update to that discussion.

Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue

As discussed in the Form 10-K, in February 2023, System Energy submitted a tariff compliance filing with the FERC to clarify that, consistent with the releases provided in the June 2022 MPSC settlement, Entergy Mississippi would continue to be charged for its allocation of the sale-leaseback renewal costs under the Unit Power Sales Agreement. In March 2023 the MPSC filed a protest to System Energy’s tariff compliance filing. The MPSC argued that the settlement did not specifically address post-settlement sale-leaseback renewal costs and that the sale-leaseback renewal costs may not be recovered under the Unit Power Sales Agreement. In February 2025, System Energy and the MPSC resolved their dispute concerning the sale-leaseback renewal costs. As a result, the MPSC withdrew its protest at the FERC on System Energy’s tariff compliance filing. Entergy Mississippi will continue to pay the allocated sale-leaseback renewal costs of approximately $5.7 million annually and there are no refunds due for prior periods. In March 2025, System Energy filed a status report with the FERC explaining that the dispute is resolved.
Storm Cost Recovery Filings with Retail Regulators

See Note 2 to the financial statements in the Form 10-K for discussion regarding storm cost recovery filings. The following is an update to that discussion.

Entergy Louisiana

Hurricane Francine

In September 2024, Hurricane Francine caused damage to the areas served by Entergy Louisiana. The storm resulted in widespread power outages, primarily due to damage to distribution infrastructure as a result of strong winds and heavy rain, and the loss of sales during the power outages.

In December 2024, and subsequently amended in an errata filed in February 2025, Entergy Louisiana submitted an application to the LPSC seeking a determination that approximately $183.6 million in storm restoration costs associated with Hurricane Francine were reasonable and necessary and, therefore, eligible for recovery from customers, as well as approval to recover approximately $3.6 million in certain carrying costs from customers. In February 2025, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting a revenue increase of $17.8 million from funds approved by the LPSC (on an interim basis) for Hurricane Francine recovery costs. The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the 2023 formula rate plan filing above. Also in February 2025, Entergy Louisiana withdrew $33.5 million from its funded storm reserves. In March 2025 a status conference was held in which a procedural schedule was established including a hearing in November 2025.

Entergy Arkansas

Energy Cost Recovery Rider

In March 2025, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00882 per kWh to $0.01333 per kWh. The annual redetermination included a credit related to the remaining balance due to retail customers from the System Energy settlement with the APSC, plus carrying charges and interest. See “Retail Rate Proceedings - Filings with the APSC (Entergy Arkansas) - Retail Rates - Grand Gulf Credit Rider” below for further discussion. The primary reason for the rate increase is an adjustment to account for projected increases in natural gas prices in 2025. This adjustment is expected to reduce the rate change that will be reflected in its 2026 energy cost rate redetermination. The redetermined rate of $0.01333 per kWh became effective with the first billing cycle in April 2025 through the normal operation of the tariff.

Entergy Louisiana

As discussed in the Form 10-K, in January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. In April 2025 the LPSC staff issued its audit report (for Entergy Louisiana’s gas operations), which included several prospective recommendations but no financial disallowances. The next procedural step is for the LPSC to review the report; however there is no deadline for completion of the LPSC’s review.

As discussed in the Form 10-K, in October 2024, Entergy Louisiana filed an application with the LPSC seeking approval of a variety of generation and transmission resources proposed in connection with establishing service to a new data center to be developed by a subsidiary of Meta Platforms, Inc. in north Louisiana, for which an electric service agreement has been executed. The filing requests LPSC certification of three new combined cycle combustion turbine generation resources totaling 2,262 MW, each of which will be enabled for future carbon capture and storage, a new 500 kV transmission line, and 500 kV substation upgrades. The application also requests approval to implement a corporate sustainability rider applicable to the new customer. The corporate sustainability rider contemplates the new customer contributing to the costs of the future addition of 1,500 MW of new solar and energy storage resources, agreements involving carbon capture and storage at Entergy Louisiana’s existing Lake Charles Power Station, and potential future wind and nuclear resources. Entergy Louisiana anticipates funding the incremental cost to serve the customer through direct financial contributions from the customer and the revenues it expects to earn under the electric service agreement. The electric service agreement also contains provisions for termination payments that will help ensure that there is no harm to Entergy Louisiana and its customers in the event
of early termination. A directive was issued at the LPSC’s November 2024 meeting for the matter to be decided by October 2025. In February 2025 intervenors filed a motion asking the LPSC to deny Entergy Louisiana’s requested exemption from the LPSC’s order addressing competitive solicitation procedures and further asking the LPSC to dismiss the application. The ALJ issued an order denying the motion to dismiss the application and deferring the LPSC’s consideration of the motion regarding the competitive solicitation procedures until the hearing. In March 2025 the same intervenors filed a motion requesting the LPSC to require the customer and its parent company to be joined as parties to the proceeding or dismiss the application. In April 2025 the ALJ issued an order denying the March 2025 motion, and the moving parties filed a motion asking the LPSC to review and reverse the ALJ’s decision. In April 2025 the LPSC staff and intervenors filed direct testimony. The LPSC staff’s testimony discusses the significant projected benefits associated with the data center project and also recommends that the LPSC impose certain conditions on its approval, including a condition that would require, under specified circumstances, certain sharing of net revenues from service to the project with Entergy Louisiana’s other customers. The LPSC staff also recommends that the LPSC deny approval of the corporate sustainability rider terms providing for the customer to supply funding toward the cost of installing carbon capture and storage infrastructure at Entergy Louisiana’s Lake Charles Power Station. The Louisiana Energy Users Group and other intervenors recommended that the LPSC require various changes to the terms of the electric service agreement with the customer that would shift additional risk and cost to the customer rather than Entergy Louisiana’s broader customer base. Certain intervenors also challenged approval on the basis that Entergy Louisiana did not conduct a request for proposals to procure the proposed generation resources to serve the customer’s project; these intervenors also advocate that Entergy Louisiana be required to procure more renewable generation and evaluate transmission alternatives rather than proceeding with development of all of the proposed new generation resources. Entergy Louisiana’s rebuttal testimony is due in May 2025, and a hearing is set for July 2025.

Filings with the MPSC (Entergy Mississippi)

Retail Rates

2025 Formula Rate Plan Filing

In February 2025, Entergy Mississippi submitted its formula rate plan 2025 test year filing and 2024 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2024 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2025 calendar year to also be within the formula rate plan bandwidth. The 2025 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2024 look-back filing compared actual 2024 results to the approved benchmark return on rate base and reflected no change in formula rate plan revenues, although Entergy Mississippi proposes to adjust interim rates by $135 thousand to reflect two outside-the-bandwidth changes: (1) the completion of Entergy Mississippi’s return to customers of credits under its restructuring credit rider; and (2) a true-up of demand side management costs. A final order is expected in second quarter 2025.

Interim Facilities Rate Adjustments

In May 2024, Entergy Mississippi received approval from the MPSC for formula rate plan revisions that were necessary for Entergy Mississippi to comply with state legislation passed in January 2024. The legislation allows Entergy Mississippi to make interim rate adjustments to recover the non-fuel related annual ownership cost of certain facilities that directly or indirectly provide service to customers who own certain data processing center projects as specified in the legislation. Entergy Mississippi filed the first of its annual interim facilities rate adjustment reports in May 2024 to recover approximately $8.7 million of these costs over a six-month period with rates effective beginning in July 2024. Entergy Mississippi filed its second interim facilities rate adjustment report in November 2024 to recover approximately $46.7 million of these costs over a 12-month period with rates effective beginning in January 2025. In February 2025, Entergy Mississippi filed a true-up interim facilities rate adjustment report to the initial annual interim facilities rate adjustment report filed in May 2024, reflecting the recovery of an
additional approximately $1.0 million of costs over a 12-month period with rates effective with the first billing cycle of April 2025.

Filings with the City Council (Entergy New Orleans)

Retail Rates

2025 Formula Rate Plan Filing

In April 2025, Entergy New Orleans submitted to the City Council its formula rate plan 2024 test year filing. The 2024 evaluation report produced an electric earned return on equity of 10.98% and a gas earned return on equity of 8.96% compared to the authorized return on equity for each of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million and no change in gas rates. The decrease in electric rates is driven by the realignment of regulatory liabilities into the formula from a separate rate mechanism, partially offset by the cost of known and measurable electric capital additions. The filing also commences the previously authorized recovery of certain regulatory costs and requests a revenue-neutral recovery to offset a proposed reduction in bill payment late fees. Taking into account these proposed adjustments, the filing presents a decrease in authorized electric revenues of $8.6 million and an increase in authorized gas revenues of $0.5 million. The filing is subject to a 75-day review period, followed by a 25-day period to resolve any disputes among the parties. For any disputed rate adjustments, however, the City Council would set a procedural schedule to resolve. Resulting rates will be effective with the first billing cycle of September 2025 pursuant to the formula rate plan tariff.

Retail Rates

Distribution Cost Recovery Factor (DCRF) Rider

In April 2025, Entergy Texas filed with the PUCT a request to amend its DCRF rider. The proposed rider is designed to collect from Entergy Texas’s retail customers approximately $77.8 million annually, or $29.3 million in incremental annual revenues beyond Entergy Texas’s currently effective DCRF rider based on its capital invested in distribution between July 1, 2024 and December 31, 2024, including distribution-related restoration costs associated with Hurricane Beryl.

Transmission Cost Recovery Factor (TCRF) Rider

As discussed in the Form 10-K, in October 2024, Entergy Texas filed with the PUCT a request to amend its TCRF rider, which was previously reset to zero in June 2023 as a result of the 2022 base rate case. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $9.7 million annually based on its capital invested in transmission between January 1, 2022 and June 30, 2024 and changes in other transmission charges. In April 2025 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 7, 2025.

Entergy Arkansas Opportunity Sales Proceeding

As discussed in the Form 10-K, in September 2020, Entergy Arkansas filed a complaint in the U.S. District Court for the Eastern District of Arkansas challenging the APSC’s denial of recovery of $135 million of payments to other Utility operating companies in December 2018 relating to off-system sales of electricity from 2002-2009, as ordered by the FERC. The complaint also involved a challenge to the $13.7 million, plus interest, of related refunds ordered by the APSC and paid by Entergy Arkansas in August 2020. The trial was held in February 2023.
In March 2024 the U.S. District Court for the Eastern District of Arkansas issued a judgment in favor of the APSC and against Entergy Arkansas. In March 2024 Entergy Arkansas filed a notice of appeal and a motion to expedite oral arguments with the United States Court of Appeals for the Eighth Circuit and the court granted the motion to expedite. As a result of the adverse decision by the U.S. District Court for the Eastern District of Arkansas, Entergy Arkansas concluded that it could no longer support the recognition of its $131.8 million regulatory asset reflecting the previously-expected recovery of a portion of the costs at issue in the opportunity sales proceeding and recorded a $131.8 million ($99.1 million net-of-tax) charge to earnings in first quarter 2024. In December 2024 the United States Court of Appeals for the Eighth Circuit affirmed the decision of the U.S. District Court for the Eastern District of Arkansas, and Entergy Arkansas filed a petition for rehearing en banc. In January 2025 the United States Court of Appeals for the Eighth Circuit denied Entergy Arkansas’s petition. In April 2025, Entergy Arkansas filed a petition for certiorari with the United States Supreme Court.

MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding

See Note 2 to the financial statements in the Form 10-K for discussion of the MSS-4 replacement tariff net operating loss carryforward proceeding.

The MSS-4 replacement tariff, a tariff governing the sales of energy and capacity among the Utility operating companies, includes protocols that provide for the disclosure of cost inputs, an opportunity for informal discovery procedures, and a challenge process. In April 2025, pursuant to such protocols, the City Council filed with the FERC a formal challenge relating to Entergy Services’ inclusion and allocation of net operating loss carryforward accumulated deferred income taxes in the MSS-4 replacement tariff rates charged to Entergy New Orleans’s monthly bills for calendar year 2023. Entergy Services plans to file a response to the formal challenge by the May 2025 deadline.

Complaints Against System Energy

See Note 2 to the financial statements in the Form 10-K for information regarding pending complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. The following is an update to that discussion.

Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue

As discussed in the Form 10-K, in February 2023, System Energy submitted a tariff compliance filing with the FERC to clarify that, consistent with the releases provided in the June 2022 MPSC settlement, Entergy Mississippi would continue to be charged for its allocation of the sale-leaseback renewal costs under the Unit Power Sales Agreement. In March 2023 the MPSC filed a protest to System Energy’s tariff compliance filing. The MPSC argued that the settlement did not specifically address post-settlement sale-leaseback renewal costs and that the sale-leaseback renewal costs may not be recovered under the Unit Power Sales Agreement. In February 2025, System Energy and the MPSC resolved their dispute concerning the sale-leaseback renewal costs. As a result, the MPSC withdrew its protest at the FERC on System Energy’s tariff compliance filing. Entergy Mississippi will continue to pay the allocated sale-leaseback renewal costs of approximately $5.7 million annually and there are no refunds due for prior periods. In March 2025, System Energy filed a status report with the FERC explaining that the dispute is resolved.
Storm Cost Recovery Filings with Retail Regulators

See Note 2 to the financial statements in the Form 10-K for discussion regarding storm cost recovery filings. The following is an update to that discussion.

Entergy Louisiana

Hurricane Francine

In September 2024, Hurricane Francine caused damage to the areas served by Entergy Louisiana. The storm resulted in widespread power outages, primarily due to damage to distribution infrastructure as a result of strong winds and heavy rain, and the loss of sales during the power outages.

In December 2024, and subsequently amended in an errata filed in February 2025, Entergy Louisiana submitted an application to the LPSC seeking a determination that approximately $183.6 million in storm restoration costs associated with Hurricane Francine were reasonable and necessary and, therefore, eligible for recovery from customers, as well as approval to recover approximately $3.6 million in certain carrying costs from customers. In February 2025, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting a revenue increase of $17.8 million from funds approved by the LPSC (on an interim basis) for Hurricane Francine recovery costs. The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the 2023 formula rate plan filing above. Also in February 2025, Entergy Louisiana withdrew $33.5 million from its funded storm reserves. In March 2025 a status conference was held in which a procedural schedule was established including a hearing in November 2025.

Fuel and purchased power cost recovery

Entergy Arkansas

Energy Cost Recovery Rider

In March 2025, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00882 per kWh to $0.01333 per kWh. The annual redetermination included a credit related to the remaining balance due to retail customers from the System Energy settlement with the APSC, plus carrying charges and interest. See “Retail Rate Proceedings - Filings with the APSC (Entergy Arkansas) - Retail Rates - Grand Gulf Credit Rider” below for further discussion. The primary reason for the rate increase is an adjustment to account for projected increases in natural gas prices in 2025. This adjustment is expected to reduce the rate change that will be reflected in its 2026 energy cost rate redetermination. The redetermined rate of $0.01333 per kWh became effective with the first billing cycle in April 2025 through the normal operation of the tariff.

Entergy Louisiana

As discussed in the Form 10-K, in January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. In April 2025 the LPSC staff issued its audit report (for Entergy Louisiana’s gas operations), which included several prospective recommendations but no financial disallowances. The next procedural step is for the LPSC to review the report; however there is no deadline for completion of the LPSC’s review.

Grand Gulf Credit Rider

As discussed in the Form 10-K, in June 2024, Entergy Arkansas filed with the APSC a tariff to provide retail customers a credit resulting from the terms of the settlement agreement between Entergy Arkansas, System Energy, additional named Entergy parties, and the APSC pertaining to System Energy’s billings for wholesale sales of energy and capacity from the Grand Gulf nuclear plant. See “Complaints Against System Energy - System Energy Settlement with the APSC” in Note 2 to the financial statements in the Form 10-K for discussion of the System Energy settlement with the APSC. In July 2024 the APSC approved the tariff, under which Entergy Arkansas would refund to retail customers a total of $100.6 million. Entergy Arkansas refunded $92.3 million of
the total through one-time bill credits under the Grand Gulf credit rider during the August 2024 billing cycle. In March 2025, Entergy Arkansas included the remaining balance as a credit to retail customers in its energy cost recovery rider rate redetermination filing. See further discussion within "Regulatory Assets and Regulatory Liabilities - Fuel and purchased power cost recovery - Entergy Arkansas - Energy Cost Recovery Rider" above. In April 2025 the APSC approved Entergy Arkansas’s proposal to include the remaining balance in its energy cost recovery rider effective with the first billing cycle of April 2025 and the withdrawal of the Grand Gulf credit rider after all credits have been issued.

2023 Formula Rate Plan Filing

As discussed in the Form 10-K, in August 2024, pursuant to the global stipulated settlement agreement, Entergy Louisiana filed its formula rate plan evaluation report for its 2023 calendar year operations. Consistent with the global stipulated settlement agreement, the filing reflected a 9.7% allowed return on common equity with a bandwidth of 40 basis points above and below the midpoint. For the 2023 test year, however, the bandwidth provisions of the formula rate plan are temporarily suspended and, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana implemented the September 2024 formula rate plan rate adjustments effective with the first billing cycle of September 2024. In January 2025, Entergy Louisiana and the LPSC filed a joint report indicating that no disputed issues remained in the proceeding and requesting that the LPSC issue an order accepting Entergy Louisiana’s evaluation report and, ultimately, resolving this matter. In March 2025 the LPSC issued an order accepting the evaluation report.

In December 2024, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed an interim rate adjustment for the 2023 test year reflecting the return of $25.1 million of refunds from the System Energy settlement with the LPSC to customers from January through August 2025. In February 2025, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting the divestiture of Entergy Louisiana’s share of Grand Gulf capacity and energy, which was effective as of January 1, 2025. The second interim rate adjustment also reflected a revenue increase of $17.8 million for the recovery of Hurricane Francine costs as approved by the LPSC (on an interim basis). The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the Hurricane Francine proceeding in “Storm Cost Recovery Filings with Retail Regulators – Entergy Louisiana – Hurricane Francine” below. See Note 8 to the financial statements in the Form 10-K for discussion of Entergy Louisiana’s divestiture from the Unit Power Sales Agreement.

Additional Generation and Transmission Resources

As discussed in the Form 10-K, in October 2024, Entergy Louisiana filed an application with the LPSC seeking approval of a variety of generation and transmission resources proposed in connection with establishing service to a new data center to be developed by a subsidiary of Meta Platforms, Inc. in north Louisiana, for which an electric service agreement has been executed. The filing requests LPSC certification of three new combined cycle combustion turbine generation resources totaling 2,262 MW, each of which will be enabled for future carbon capture and storage, a new 500 kV transmission line, and 500 kV substation upgrades. The application also requests approval to implement a corporate sustainability rider applicable to the new customer. The corporate sustainability rider contemplates the new customer contributing to the costs of the future addition of 1,500 MW of new solar and energy storage resources, agreements involving carbon capture and storage at Entergy Louisiana’s existing Lake Charles Power Station, and potential future wind and nuclear resources. Entergy Louisiana anticipates funding the incremental cost to serve the customer through direct financial contributions from the customer and the revenues it expects to earn under the electric service agreement. The electric service agreement also contains provisions for termination payments that will help ensure that there is no harm to Entergy Louisiana and its customers in the event
of early termination. A directive was issued at the LPSC’s November 2024 meeting for the matter to be decided by October 2025. In February 2025 intervenors filed a motion asking the LPSC to deny Entergy Louisiana’s requested exemption from the LPSC’s order addressing competitive solicitation procedures and further asking the LPSC to dismiss the application. The ALJ issued an order denying the motion to dismiss the application and deferring the LPSC’s consideration of the motion regarding the competitive solicitation procedures until the hearing. In March 2025 the same intervenors filed a motion requesting the LPSC to require the customer and its parent company to be joined as parties to the proceeding or dismiss the application. In April 2025 the ALJ issued an order denying the March 2025 motion, and the moving parties filed a motion asking the LPSC to review and reverse the ALJ’s decision. In April 2025 the LPSC staff and intervenors filed direct testimony. The LPSC staff’s testimony discusses the significant projected benefits associated with the data center project and also recommends that the LPSC impose certain conditions on its approval, including a condition that would require, under specified circumstances, certain sharing of net revenues from service to the project with Entergy Louisiana’s other customers. The LPSC staff also recommends that the LPSC deny approval of the corporate sustainability rider terms providing for the customer to supply funding toward the cost of installing carbon capture and storage infrastructure at Entergy Louisiana’s Lake Charles Power Station. The Louisiana Energy Users Group and other intervenors recommended that the LPSC require various changes to the terms of the electric service agreement with the customer that would shift additional risk and cost to the customer rather than Entergy Louisiana’s broader customer base. Certain intervenors also challenged approval on the basis that Entergy Louisiana did not conduct a request for proposals to procure the proposed generation resources to serve the customer’s project; these intervenors also advocate that Entergy Louisiana be required to procure more renewable generation and evaluate transmission alternatives rather than proceeding with development of all of the proposed new generation resources.

In April 2025, Entergy New Orleans submitted to the City Council its formula rate plan 2024 test year filing. The 2024 evaluation report produced an electric earned return on equity of 10.98% and a gas earned return on equity of 8.96% compared to the authorized return on equity for each of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million and no change in gas rates. The decrease in electric rates is driven by the realignment of regulatory liabilities into the formula from a separate rate mechanism, partially offset by the cost of known and measurable electric capital additions. The filing also commences the previously authorized recovery of certain regulatory costs and requests a revenue-neutral recovery to offset a proposed reduction in bill payment late fees. Taking into account these proposed adjustments, the filing presents a decrease in authorized electric revenues of $8.6 million and an increase in authorized gas revenues of $0.5 million. The filing is subject to a 75-day review period, followed by a 25-day period to resolve any disputes among the parties. For any disputed rate adjustments, however, the City Council would set a procedural schedule to resolve. Resulting rates will be effective with the first billing cycle of September 2025 pursuant to the formula rate plan tariff.

Distribution Cost Recovery Factor (DCRF) Rider

In April 2025, Entergy Texas filed with the PUCT a request to amend its DCRF rider. The proposed rider is designed to collect from Entergy Texas’s retail customers approximately $77.8 million annually, or $29.3 million in incremental annual revenues beyond Entergy Texas’s currently effective DCRF rider based on its capital invested in distribution between July 1, 2024 and December 31, 2024, including distribution-related restoration costs associated with Hurricane Beryl.

Transmission Cost Recovery Factor (TCRF) Rider

As discussed in the Form 10-K, in October 2024, Entergy Texas filed with the PUCT a request to amend its TCRF rider, which was previously reset to zero in June 2023 as a result of the 2022 base rate case. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $9.7 million annually based on its capital invested in transmission between January 1, 2022 and June 30, 2024 and changes in other transmission charges. In April 2025 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 7, 2025.

Entergy Arkansas Opportunity Sales Proceeding

As discussed in the Form 10-K, in September 2020, Entergy Arkansas filed a complaint in the U.S. District Court for the Eastern District of Arkansas challenging the APSC’s denial of recovery of $135 million of payments to other Utility operating companies in December 2018 relating to off-system sales of electricity from 2002-2009, as ordered by the FERC. The complaint also involved a challenge to the $13.7 million, plus interest, of related refunds ordered by the APSC and paid by Entergy Arkansas in August 2020. The trial was held in February 2023.
In March 2024 the U.S. District Court for the Eastern District of Arkansas issued a judgment in favor of the APSC and against Entergy Arkansas. In March 2024 Entergy Arkansas filed a notice of appeal and a motion to expedite oral arguments with the United States Court of Appeals for the Eighth Circuit and the court granted the motion to expedite. As a result of the adverse decision by the U.S. District Court for the Eastern District of Arkansas, Entergy Arkansas concluded that it could no longer support the recognition of its $131.8 million regulatory asset reflecting the previously-expected recovery of a portion of the costs at issue in the opportunity sales proceeding and recorded a $131.8 million ($99.1 million net-of-tax) charge to earnings in first quarter 2024. In December 2024 the United States Court of Appeals for the Eighth Circuit affirmed the decision of the U.S. District Court for the Eastern District of Arkansas, and Entergy Arkansas filed a petition for rehearing en banc. In January 2025 the United States Court of Appeals for the Eighth Circuit denied Entergy Arkansas’s petition. In April 2025, Entergy Arkansas filed a petition for certiorari with the United States Supreme Court.

Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue

As discussed in the Form 10-K, in February 2023, System Energy submitted a tariff compliance filing with the FERC to clarify that, consistent with the releases provided in the June 2022 MPSC settlement, Entergy Mississippi would continue to be charged for its allocation of the sale-leaseback renewal costs under the Unit Power Sales Agreement. In March 2023 the MPSC filed a protest to System Energy’s tariff compliance filing. The MPSC argued that the settlement did not specifically address post-settlement sale-leaseback renewal costs and that the sale-leaseback renewal costs may not be recovered under the Unit Power Sales Agreement. In February 2025, System Energy and the MPSC resolved their dispute concerning the sale-leaseback renewal costs. As a result, the MPSC withdrew its protest at the FERC on System Energy’s tariff compliance filing. Entergy Mississippi will continue to pay the allocated sale-leaseback renewal costs of approximately $5.7 million annually and there are no refunds due for prior periods. In March 2025, System Energy filed a status report with the FERC explaining that the dispute is resolved.
Storm Cost Recovery Filings with Retail Regulators

See Note 2 to the financial statements in the Form 10-K for discussion regarding storm cost recovery filings. The following is an update to that discussion.

Entergy Louisiana

Hurricane Francine

In September 2024, Hurricane Francine caused damage to the areas served by Entergy Louisiana. The storm resulted in widespread power outages, primarily due to damage to distribution infrastructure as a result of strong winds and heavy rain, and the loss of sales during the power outages.

In December 2024, and subsequently amended in an errata filed in February 2025, Entergy Louisiana submitted an application to the LPSC seeking a determination that approximately $183.6 million in storm restoration costs associated with Hurricane Francine were reasonable and necessary and, therefore, eligible for recovery from customers, as well as approval to recover approximately $3.6 million in certain carrying costs from customers. In February 2025, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting a revenue increase of $17.8 million from funds approved by the LPSC (on an interim basis) for Hurricane Francine recovery costs. The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the 2023 formula rate plan filing above. Also in February 2025, Entergy Louisiana withdrew $33.5 million from its funded storm reserves.

Fuel and purchased power cost recovery

Entergy Arkansas

Energy Cost Recovery Rider

In March 2025, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00882 per kWh to $0.01333 per kWh. The annual redetermination included a credit related to the remaining balance due to retail customers from the System Energy settlement with the APSC, plus carrying charges and interest. See “Retail Rate Proceedings - Filings with the APSC (Entergy Arkansas) - Retail Rates - Grand Gulf Credit Rider” below for further discussion. The primary reason for the rate increase is an adjustment to account for projected increases in natural gas prices in 2025. This adjustment is expected to reduce the rate change that will be reflected in its 2026 energy cost rate redetermination. The redetermined rate of $0.01333 per kWh became effective with the first billing cycle in April 2025 through the normal operation of the tariff.

Entergy Louisiana

As discussed in the Form 10-K, in January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. In April 2025 the LPSC staff issued its audit report (for Entergy Louisiana’s gas operations), which included several prospective recommendations but no financial disallowances. The next procedural step is for the LPSC to review the report; however there is no deadline for completion of the LPSC’s review.

Retail Rate Proceedings

See Note 2 to the financial statements in the Form 10-K for information regarding retail rate proceedings involving the Utility operating companies. The following are updates to that discussion.

Filings with the APSC (Entergy Arkansas)

Retail Rates

Grand Gulf Credit Rider

As discussed in the Form 10-K, in June 2024, Entergy Arkansas filed with the APSC a tariff to provide retail customers a credit resulting from the terms of the settlement agreement between Entergy Arkansas, System Energy, additional named Entergy parties, and the APSC pertaining to System Energy’s billings for wholesale sales of energy and capacity from the Grand Gulf nuclear plant. See “Complaints Against System Energy - System Energy Settlement with the APSC” in Note 2 to the financial statements in the Form 10-K for discussion of the System Energy settlement with the APSC. In July 2024 the APSC approved the tariff, under which Entergy Arkansas would refund to retail customers a total of $100.6 million. Entergy Arkansas refunded $92.3 million of
the total through one-time bill credits under the Grand Gulf credit rider during the August 2024 billing cycle. In March 2025, Entergy Arkansas included the remaining balance as a credit to retail customers in its energy cost recovery rider rate redetermination filing. See further discussion within "Regulatory Assets and Regulatory Liabilities - Fuel and purchased power cost recovery - Entergy Arkansas - Energy Cost Recovery Rider" above. In April 2025 the APSC approved Entergy Arkansas’s proposal to include the remaining balance in its energy cost recovery rider effective with the first billing cycle of April 2025 and the withdrawal of the Grand Gulf credit rider after all credits have been issued.

2023 Formula Rate Plan Filing

As discussed in the Form 10-K, in August 2024, pursuant to the global stipulated settlement agreement, Entergy Louisiana filed its formula rate plan evaluation report for its 2023 calendar year operations. Consistent with the global stipulated settlement agreement, the filing reflected a 9.7% allowed return on common equity with a bandwidth of 40 basis points above and below the midpoint. For the 2023 test year, however, the bandwidth provisions of the formula rate plan are temporarily suspended and, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana implemented the September 2024 formula rate plan rate adjustments effective with the first billing cycle of September 2024. In January 2025, Entergy Louisiana and the LPSC filed a joint report indicating that no disputed issues remained in the proceeding and requesting that the LPSC issue an order accepting Entergy Louisiana’s evaluation report and, ultimately, resolving this matter. In March 2025 the LPSC issued an order accepting the evaluation report.

In December 2024, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed an interim rate adjustment for the 2023 test year reflecting the return of $25.1 million of refunds from the System Energy settlement with the LPSC to customers from January through August 2025. In February 2025, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting the divestiture of Entergy Louisiana’s share of Grand Gulf capacity and energy, which was effective as of January 1, 2025. The second interim rate adjustment also reflected a revenue increase of $17.8 million for the recovery of Hurricane Francine costs as approved by the LPSC (on an interim basis). The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the Hurricane Francine proceeding in “Storm Cost Recovery Filings with Retail Regulators – Entergy Louisiana – Hurricane Francine” below. See Note 8 to the financial statements in the Form 10-K for discussion of Entergy Louisiana’s divestiture from the Unit Power Sales Agreement.

Additional Generation and Transmission Resources

As discussed in the Form 10-K, in October 2024, Entergy Louisiana filed an application with the LPSC seeking approval of a variety of generation and transmission resources proposed in connection with establishing service to a new data center to be developed by a subsidiary of Meta Platforms, Inc. in north Louisiana, for which an electric service agreement has been executed. The filing requests LPSC certification of three new combined cycle combustion turbine generation resources totaling 2,262 MW, each of which will be enabled for future carbon capture and storage, a new 500 kV transmission line, and 500 kV substation upgrades. The application also requests approval to implement a corporate sustainability rider applicable to the new customer. The corporate sustainability rider contemplates the new customer contributing to the costs of the future addition of 1,500 MW of new solar and energy storage resources, agreements involving carbon capture and storage at Entergy Louisiana’s existing Lake Charles Power Station, and potential future wind and nuclear resources. Entergy Louisiana anticipates funding the incremental cost to serve the customer through direct financial contributions from the customer and the revenues it expects to earn under the electric service agreement. The electric service agreement also contains provisions for termination payments that will help ensure that there is no harm to Entergy Louisiana and its customers in the event
of early termination. A directive was issued at the LPSC’s November 2024 meeting for the matter to be decided by October 2025. In February 2025 intervenors filed a motion asking the LPSC to deny Entergy Louisiana’s requested exemption from the LPSC’s order addressing competitive solicitation procedures and further asking the LPSC to dismiss the application. The ALJ issued an order denying the motion to dismiss the application and deferring the LPSC’s consideration of the motion regarding the competitive solicitation procedures until the hearing. In March 2025 the same intervenors filed a motion requesting the LPSC to require the customer and its parent company to be joined as parties to the proceeding or dismiss the application. In April 2025 the ALJ issued an order denying the March 2025 motion, and the moving parties filed a motion asking the LPSC to review and reverse the ALJ’s decision. In April 2025 the LPSC staff and intervenors filed direct testimony. The LPSC staff’s testimony discusses the significant projected benefits associated with the data center project and also recommends that the LPSC impose certain conditions on its approval, including a condition that would require, under specified circumstances, certain sharing of net revenues from service to the project with Entergy Louisiana’s other customers. The LPSC staff also recommends that the LPSC deny approval of the corporate sustainability rider terms providing for the customer to supply funding toward the cost of installing carbon capture and storage infrastructure at Entergy Louisiana’s Lake Charles Power Station. The Louisiana Energy Users Group and other intervenors recommended that the LPSC require various changes to the terms of the electric service agreement with the customer that would shift additional risk and cost to the customer rather than Entergy Louisiana’s broader customer base. Certain intervenors also challenged approval on the basis that Entergy Louisiana did not conduct a request for proposals to procure the proposed generation resources to serve the customer’s project; these intervenors also advocate that Entergy Louisiana be required to procure more renewable generation and evaluate transmission alternatives rather than proceeding with development of all of the proposed new generation resources. Entergy Louisiana’s rebuttal testimony is due in May 2025, and a hearing is set for July 2025.

Filings with the MPSC (Entergy Mississippi)

Retail Rates

2025 Formula Rate Plan Filing

In February 2025, Entergy Mississippi submitted its formula rate plan 2025 test year filing and 2024 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2024 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2025 calendar year to also be within the formula rate plan bandwidth. The 2025 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2024 look-back filing compared actual 2024 results to the approved benchmark return on rate base and reflected no change in formula rate plan revenues, although Entergy Mississippi proposes to adjust interim rates by $135 thousand to reflect two outside-the-bandwidth changes: (1) the completion of Entergy Mississippi’s return to customers of credits under its restructuring credit rider; and (2) a true-up of demand side management costs. A final order is expected in second quarter 2025.

Interim Facilities Rate Adjustments

In May 2024, Entergy Mississippi received approval from the MPSC for formula rate plan revisions that were necessary for Entergy Mississippi to comply with state legislation passed in January 2024. The legislation allows Entergy Mississippi to make interim rate adjustments to recover the non-fuel related annual ownership cost of certain facilities that directly or indirectly provide service to customers who own certain data processing center projects as specified in the legislation. Entergy Mississippi filed the first of its annual interim facilities rate adjustment reports in May 2024 to recover approximately $8.7 million of these costs over a six-month period with rates effective beginning in July 2024. Entergy Mississippi filed its second interim facilities rate adjustment report in November 2024 to recover approximately $46.7 million of these costs over a 12-month period with rates effective beginning in January 2025. In February 2025, Entergy Mississippi filed a true-up interim facilities rate adjustment report to the initial annual interim facilities rate adjustment report filed in May 2024, reflecting the recovery of an
additional approximately $1.0 million of costs over a 12-month period with rates effective with the first billing cycle of April 2025.

Filings with the City Council (Entergy New Orleans)

Retail Rates

2025 Formula Rate Plan Filing

In April 2025, Entergy New Orleans submitted to the City Council its formula rate plan 2024 test year filing. The 2024 evaluation report produced an electric earned return on equity of 10.98% and a gas earned return on equity of 8.96% compared to the authorized return on equity for each of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million and no change in gas rates. The decrease in electric rates is driven by the realignment of regulatory liabilities into the formula from a separate rate mechanism, partially offset by the cost of known and measurable electric capital additions. The filing also commences the previously authorized recovery of certain regulatory costs and requests a revenue-neutral recovery to offset a proposed reduction in bill payment late fees. Taking into account these proposed adjustments, the filing presents a decrease in authorized electric revenues of $8.6 million and an increase in authorized gas revenues of $0.5 million. The filing is subject to a 75-day review period, followed by a 25-day period to resolve any disputes among the parties. For any disputed rate adjustments, however, the City Council would set a procedural schedule to resolve. Resulting rates will be effective with the first billing cycle of September 2025 pursuant to the formula rate plan tariff.

Filings with the PUCT and Texas Cities (Entergy Texas)

Retail Rates

Distribution Cost Recovery Factor (DCRF) Rider

In April 2025, Entergy Texas filed with the PUCT a request to amend its DCRF rider. The proposed rider is designed to collect from Entergy Texas’s retail customers approximately $77.8 million annually, or $29.3 million in incremental annual revenues beyond Entergy Texas’s currently effective DCRF rider based on its capital invested in distribution between July 1, 2024 and December 31, 2024, including distribution-related restoration costs associated with Hurricane Beryl.

Transmission Cost Recovery Factor (TCRF) Rider

As discussed in the Form 10-K, in October 2024, Entergy Texas filed with the PUCT a request to amend its TCRF rider, which was previously reset to zero in June 2023 as a result of the 2022 base rate case. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $9.7 million annually based on its capital invested in transmission between January 1, 2022 and June 30, 2024 and changes in other transmission charges. In April 2025 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 7, 2025.

Entergy Arkansas Opportunity Sales Proceeding

As discussed in the Form 10-K, in September 2020, Entergy Arkansas filed a complaint in the U.S. District Court for the Eastern District of Arkansas challenging the APSC’s denial of recovery of $135 million of payments to other Utility operating companies in December 2018 relating to off-system sales of electricity from 2002-2009, as ordered by the FERC. The complaint also involved a challenge to the $13.7 million, plus interest, of related refunds ordered by the APSC and paid by Entergy Arkansas in August 2020. The trial was held in February 2023.
In March 2024 the U.S. District Court for the Eastern District of Arkansas issued a judgment in favor of the APSC and against Entergy Arkansas. In March 2024 Entergy Arkansas filed a notice of appeal and a motion to expedite oral arguments with the United States Court of Appeals for the Eighth Circuit and the court granted the motion to expedite. As a result of the adverse decision by the U.S. District Court for the Eastern District of Arkansas, Entergy Arkansas concluded that it could no longer support the recognition of its $131.8 million regulatory asset reflecting the previously-expected recovery of a portion of the costs at issue in the opportunity sales proceeding and recorded a $131.8 million ($99.1 million net-of-tax) charge to earnings in first quarter 2024. In December 2024 the United States Court of Appeals for the Eighth Circuit affirmed the decision of the U.S. District Court for the Eastern District of Arkansas, and Entergy Arkansas filed a petition for rehearing en banc. In January 2025 the United States Court of Appeals for the Eighth Circuit denied Entergy Arkansas’s petition. In April 2025, Entergy Arkansas filed a petition for certiorari with the United States Supreme Court.

MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding

See Note 2 to the financial statements in the Form 10-K for discussion of the MSS-4 replacement tariff net operating loss carryforward proceeding.

The MSS-4 replacement tariff, a tariff governing the sales of energy and capacity among the Utility operating companies, includes protocols that provide for the disclosure of cost inputs, an opportunity for informal discovery procedures, and a challenge process. In April 2025, pursuant to such protocols, the City Council filed with the FERC a formal challenge relating to Entergy Services’ inclusion and allocation of net operating loss carryforward accumulated deferred income taxes in the MSS-4 replacement tariff rates charged to Entergy New Orleans’s monthly bills for calendar year 2023. Entergy Services plans to file a response to the formal challenge by the May 2025 deadline.

Complaints Against System Energy

See Note 2 to the financial statements in the Form 10-K for information regarding pending complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. The following is an update to that discussion.

Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue

As discussed in the Form 10-K, in February 2023, System Energy submitted a tariff compliance filing with the FERC to clarify that, consistent with the releases provided in the June 2022 MPSC settlement, Entergy Mississippi would continue to be charged for its allocation of the sale-leaseback renewal costs under the Unit Power Sales Agreement. In March 2023 the MPSC filed a protest to System Energy’s tariff compliance filing. The MPSC argued that the settlement did not specifically address post-settlement sale-leaseback renewal costs and that the sale-leaseback renewal costs may not be recovered under the Unit Power Sales Agreement. In February 2025, System Energy and the MPSC resolved their dispute concerning the sale-leaseback renewal costs. As a result, the MPSC withdrew its protest at the FERC on System Energy’s tariff compliance filing. Entergy Mississippi will continue to pay the allocated sale-leaseback renewal costs of approximately $5.7 million annually and there are no refunds due for prior periods. In March 2025, System Energy filed a status report with the FERC explaining that the dispute is resolved.
Storm Cost Recovery Filings with Retail Regulators

See Note 2 to the financial statements in the Form 10-K for discussion regarding storm cost recovery filings. The following is an update to that discussion.

Entergy Louisiana

Hurricane Francine

In September 2024, Hurricane Francine caused damage to the areas served by Entergy Louisiana. The storm resulted in widespread power outages, primarily due to damage to distribution infrastructure as a result of strong winds and heavy rain, and the loss of sales during the power outages.

In December 2024, and subsequently amended in an errata filed in February 2025, Entergy Louisiana submitted an application to the LPSC seeking a determination that approximately $183.6 million in storm restoration costs associated with Hurricane Francine were reasonable and necessary and, therefore, eligible for recovery from customers, as well as approval to recover approximately $3.6 million in certain carrying costs from customers. In February 2025, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting a revenue increase of $17.8 million from funds approved by the LPSC (on an interim basis) for Hurricane Francine recovery costs. The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the 2023 formula rate plan filing above. Also in February 2025, Entergy Louisiana withdrew $33.5 million from its funded storm reserves. In March 2025 a status conference was held in which a procedural schedule was established including a hearing in November 2025.

Entergy Arkansas

Energy Cost Recovery Rider

In March 2025, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00882 per kWh to $0.01333 per kWh. The annual redetermination included a credit related to the remaining balance due to retail customers from the System Energy settlement with the APSC, plus carrying charges and interest. See “Retail Rate Proceedings - Filings with the APSC (Entergy Arkansas) - Retail Rates - Grand Gulf Credit Rider” below for further discussion. The primary reason for the rate increase is an adjustment to account for projected increases in natural gas prices in 2025. This adjustment is expected to reduce the rate change that will be reflected in its 2026 energy cost rate redetermination. The redetermined rate of $0.01333 per kWh became effective with the first billing cycle in April 2025 through the normal operation of the tariff.

Entergy Louisiana

As discussed in the Form 10-K, in January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. In April 2025 the LPSC staff issued its audit report (for Entergy Louisiana’s gas operations), which included several prospective recommendations but no financial disallowances. The next procedural step is for the LPSC to review the report; however there is no deadline for completion of the LPSC’s review.

As discussed in the Form 10-K, in June 2024, Entergy Arkansas filed with the APSC a tariff to provide retail customers a credit resulting from the terms of the settlement agreement between Entergy Arkansas, System Energy, additional named Entergy parties, and the APSC pertaining to System Energy’s billings for wholesale sales of energy and capacity from the Grand Gulf nuclear plant. See “Complaints Against System Energy - System Energy Settlement with the APSC” in Note 2 to the financial statements in the Form 10-K for discussion of the System Energy settlement with the APSC. In July 2024 the APSC approved the tariff, under which Entergy Arkansas would refund to retail customers a total of $100.6 million. Entergy Arkansas refunded $92.3 million of
the total through one-time bill credits under the Grand Gulf credit rider during the August 2024 billing cycle. In March 2025, Entergy Arkansas included the remaining balance as a credit to retail customers in its energy cost recovery rider rate redetermination filing. See further discussion within "Regulatory Assets and Regulatory Liabilities - Fuel and purchased power cost recovery - Entergy Arkansas - Energy Cost Recovery Rider" above. In April 2025 the APSC approved Entergy Arkansas’s proposal to include the remaining balance in its energy cost recovery rider effective with the first billing cycle of April 2025 and the withdrawal of the Grand Gulf credit rider after all credits have been issued.

2023 Formula Rate Plan Filing

As discussed in the Form 10-K, in August 2024, pursuant to the global stipulated settlement agreement, Entergy Louisiana filed its formula rate plan evaluation report for its 2023 calendar year operations. Consistent with the global stipulated settlement agreement, the filing reflected a 9.7% allowed return on common equity with a bandwidth of 40 basis points above and below the midpoint. For the 2023 test year, however, the bandwidth provisions of the formula rate plan are temporarily suspended and, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana implemented the September 2024 formula rate plan rate adjustments effective with the first billing cycle of September 2024. In January 2025, Entergy Louisiana and the LPSC filed a joint report indicating that no disputed issues remained in the proceeding and requesting that the LPSC issue an order accepting Entergy Louisiana’s evaluation report and, ultimately, resolving this matter. In March 2025 the LPSC issued an order accepting the evaluation report.

In December 2024, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed an interim rate adjustment for the 2023 test year reflecting the return of $25.1 million of refunds from the System Energy settlement with the LPSC to customers from January through August 2025. In February 2025, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting the divestiture of Entergy Louisiana’s share of Grand Gulf capacity and energy, which was effective as of January 1, 2025. The second interim rate adjustment also reflected a revenue increase of $17.8 million for the recovery of Hurricane Francine costs as approved by the LPSC (on an interim basis). The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the Hurricane Francine proceeding in “Storm Cost Recovery Filings with Retail Regulators – Entergy Louisiana – Hurricane Francine” below. See Note 8 to the financial statements in the Form 10-K for discussion of Entergy Louisiana’s divestiture from the Unit Power Sales Agreement.

Additional Generation and Transmission Resources

As discussed in the Form 10-K, in October 2024, Entergy Louisiana filed an application with the LPSC seeking approval of a variety of generation and transmission resources proposed in connection with establishing service to a new data center to be developed by a subsidiary of Meta Platforms, Inc. in north Louisiana, for which an electric service agreement has been executed. The filing requests LPSC certification of three new combined cycle combustion turbine generation resources totaling 2,262 MW, each of which will be enabled for future carbon capture and storage, a new 500 kV transmission line, and 500 kV substation upgrades. The application also requests approval to implement a corporate sustainability rider applicable to the new customer. The corporate sustainability rider contemplates the new customer contributing to the costs of the future addition of 1,500 MW of new solar and energy storage resources, agreements involving carbon capture and storage at Entergy Louisiana’s existing Lake Charles Power Station, and potential future wind and nuclear resources. Entergy Louisiana anticipates funding the incremental cost to serve the customer through direct financial contributions from the customer and the revenues it expects to earn under the electric service agreement. The electric service agreement also contains provisions for termination payments that will help ensure that there is no harm to Entergy Louisiana and its customers in the event

In February 2025 intervenors filed a motion asking the LPSC to deny Entergy Louisiana’s requested exemption from the LPSC’s order addressing competitive solicitation procedures and further asking the LPSC to dismiss the application. The ALJ issued an order denying the motion to dismiss the application and deferring the LPSC’s consideration of the motion regarding the competitive solicitation procedures until the hearing. In March 2025 the same intervenors filed a motion requesting the LPSC to require the customer and its parent company to be joined as parties to the proceeding or dismiss the application. In April 2025 the ALJ issued an order denying the March 2025 motion, and the moving parties filed a motion asking the LPSC to review and reverse the ALJ’s decision. In April 2025 the LPSC staff and intervenors filed direct testimony. The LPSC staff’s testimony discusses the significant projected benefits associated with the data center project and also recommends that the LPSC impose certain conditions on its approval, including a condition that would require, under specified circumstances, certain sharing of net revenues from service to the project with Entergy Louisiana’s other customers.

Retail Rates

2025 Formula Rate Plan Filing

In April 2025, Entergy New Orleans submitted to the City Council its formula rate plan 2024 test year filing. The 2024 evaluation report produced an electric earned return on equity of 10.98% and a gas earned return on equity of 8.96% compared to the authorized return on equity for each of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million and no change in gas rates. The decrease in electric rates is driven by the realignment of regulatory liabilities into the formula from a separate rate mechanism, partially offset by the cost of known and measurable electric capital additions. The filing also commences the previously authorized recovery of certain regulatory costs and requests a revenue-neutral recovery to offset a proposed reduction in bill payment late fees. Taking into account these proposed adjustments, the filing presents a decrease in authorized electric revenues of $8.6 million and an increase in authorized gas revenues of $0.5 million. The filing is subject to a 75-day review period, followed by a 25-day period to resolve any disputes among the parties. For any disputed rate adjustments, however, the City Council would set a procedural schedule to resolve. Resulting rates will be effective with the first billing cycle of September 2025 pursuant to the formula rate plan tariff.

Distribution Cost Recovery Factor (DCRF) Rider

In April 2025, Entergy Texas filed with the PUCT a request to amend its DCRF rider. The proposed rider is designed to collect from Entergy Texas’s retail customers approximately $77.8 million annually, or $29.3 million in incremental annual revenues beyond Entergy Texas’s currently effective DCRF rider based on its capital invested in distribution between July 1, 2024 and December 31, 2024, including distribution-related restoration costs associated with Hurricane Beryl.

Transmission Cost Recovery Factor (TCRF) Rider

As discussed in the Form 10-K, in October 2024, Entergy Texas filed with the PUCT a request to amend its TCRF rider, which was previously reset to zero in June 2023 as a result of the 2022 base rate case. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $9.7 million annually based on its capital invested in transmission between January 1, 2022 and June 30, 2024 and changes in other transmission charges. In April 2025 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 7, 2025.

Entergy Arkansas Opportunity Sales Proceeding

As discussed in the Form 10-K, in September 2020, Entergy Arkansas filed a complaint in the U.S. District Court for the Eastern District of Arkansas challenging the APSC’s denial of recovery of $135 million of payments to other Utility operating companies in December 2018 relating to off-system sales of electricity from 2002-2009, as ordered by the FERC. The complaint also involved a challenge to the $13.7 million, plus interest, of related refunds ordered by the APSC and paid by Entergy Arkansas in August 2020. The trial was held in February 2023.
In March 2024 the U.S. District Court for the Eastern District of Arkansas issued a judgment in favor of the APSC and against Entergy Arkansas. In March 2024 Entergy Arkansas filed a notice of appeal and a motion to expedite oral arguments with the United States Court of Appeals for the Eighth Circuit and the court granted the motion to expedite. As a result of the adverse decision by the U.S. District Court for the Eastern District of Arkansas, Entergy Arkansas concluded that it could no longer support the recognition of its $131.8 million regulatory asset reflecting the previously-expected recovery of a portion of the costs at issue in the opportunity sales proceeding and recorded a $131.8 million ($99.1 million net-of-tax) charge to earnings in first quarter 2024. In December 2024 the United States Court of Appeals for the Eighth Circuit affirmed the decision of the U.S. District Court for the Eastern District of Arkansas, and Entergy Arkansas filed a petition for rehearing en banc. In January 2025 the United States Court of Appeals for the Eighth Circuit denied Entergy Arkansas’s petition. In April 2025, Entergy Arkansas filed a petition for certiorari with the United States Supreme Court.

MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding

See Note 2 to the financial statements in the Form 10-K for discussion of the MSS-4 replacement tariff net operating loss carryforward proceeding.

The MSS-4 replacement tariff, a tariff governing the sales of energy and capacity among the Utility operating companies, includes protocols that provide for the disclosure of cost inputs, an opportunity for informal discovery procedures, and a challenge process. In April 2025, pursuant to such protocols, the City Council filed with the FERC a formal challenge relating to Entergy Services’ inclusion and allocation of net operating loss carryforward accumulated deferred income taxes in the MSS-4 replacement tariff rates charged to Entergy New Orleans’s monthly bills for calendar year 2023. Entergy Services plans to file a response to the formal challenge by the May 2025 deadline.

Complaints Against System Energy

See Note 2 to the financial statements in the Form 10-K for information regarding pending complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. The following is an update to that discussion.

Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue

As discussed in the Form 10-K, in February 2023, System Energy submitted a tariff compliance filing with the FERC to clarify that, consistent with the releases provided in the June 2022 MPSC settlement, Entergy Mississippi would continue to be charged for its allocation of the sale-leaseback renewal costs under the Unit Power Sales Agreement. In March 2023 the MPSC filed a protest to System Energy’s tariff compliance filing. The MPSC argued that the settlement did not specifically address post-settlement sale-leaseback renewal costs and that the sale-leaseback renewal costs may not be recovered under the Unit Power Sales Agreement. In February 2025, System Energy and the MPSC resolved their dispute concerning the sale-leaseback renewal costs. As a result, the MPSC withdrew its protest at the FERC on System Energy’s tariff compliance filing. Entergy Mississippi will continue to pay the allocated sale-leaseback renewal costs of approximately $5.7 million annually and there are no refunds due for prior periods. In March 2025, System Energy filed a status report with the FERC explaining that the dispute is resolved.
Storm Cost Recovery Filings with Retail Regulators

See Note 2 to the financial statements in the Form 10-K for discussion regarding storm cost recovery filings. The following is an update to that discussion.

Entergy Louisiana

Hurricane Francine

In September 2024, Hurricane Francine caused damage to the areas served by Entergy Louisiana. The storm resulted in widespread power outages, primarily due to damage to distribution infrastructure as a result of strong winds and heavy rain, and the loss of sales during the power outages.

In December 2024, and subsequently amended in an errata filed in February 2025, Entergy Louisiana submitted an application to the LPSC seeking a determination that approximately $183.6 million in storm restoration costs associated with Hurricane Francine were reasonable and necessary and, therefore, eligible for recovery from customers, as well as approval to recover approximately $3.6 million in certain carrying costs from customers. In February 2025, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting a revenue increase of $17.8 million from funds approved by the LPSC (on an interim basis) for Hurricane Francine recovery costs. The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the 2023 formula rate plan filing above. Also in February 2025, Entergy Louisiana withdrew $33.5 million from its funded storm reserves. In March 2025 a status conference was held in which a procedural schedule was established including a hearing in November 2025.

Fuel and purchased power cost recovery

Entergy Arkansas

Energy Cost Recovery Rider

In March 2025, Entergy Arkansas filed its annual redetermination of its energy cost rate pursuant to the energy cost recovery rider, which reflected an increase in the rate from $0.00882 per kWh to $0.01333 per kWh. The annual redetermination included a credit related to the remaining balance due to retail customers from the System Energy settlement with the APSC, plus carrying charges and interest. See “Retail Rate Proceedings - Filings with the APSC (Entergy Arkansas) - Retail Rates - Grand Gulf Credit Rider” below for further discussion. The primary reason for the rate increase is an adjustment to account for projected increases in natural gas prices in 2025. This adjustment is expected to reduce the rate change that will be reflected in its 2026 energy cost rate redetermination. The redetermined rate of $0.01333 per kWh became effective with the first billing cycle in April 2025 through the normal operation of the tariff.

Entergy Louisiana

As discussed in the Form 10-K, in January 2023 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from 2021 through 2022. In April 2025 the LPSC staff issued its audit report (for Entergy Louisiana’s gas operations), which included several prospective recommendations but no financial disallowances. The next procedural step is for the LPSC to review the report; however there is no deadline for completion of the LPSC’s review.

Retail Rate Proceedings

See Note 2 to the financial statements in the Form 10-K for information regarding retail rate proceedings involving the Utility operating companies. The following are updates to that discussion.

Filings with the APSC (Entergy Arkansas)

Retail Rates

Grand Gulf Credit Rider

As discussed in the Form 10-K, in June 2024, Entergy Arkansas filed with the APSC a tariff to provide retail customers a credit resulting from the terms of the settlement agreement between Entergy Arkansas, System Energy, additional named Entergy parties, and the APSC pertaining to System Energy’s billings for wholesale sales of energy and capacity from the Grand Gulf nuclear plant. See “Complaints Against System Energy - System Energy Settlement with the APSC” in Note 2 to the financial statements in the Form 10-K for discussion of the System Energy settlement with the APSC. In July 2024 the APSC approved the tariff, under which Entergy Arkansas would refund to retail customers a total of $100.6 million. Entergy Arkansas refunded $92.3 million of
the total through one-time bill credits under the Grand Gulf credit rider during the August 2024 billing cycle. In March 2025, Entergy Arkansas included the remaining balance as a credit to retail customers in its energy cost recovery rider rate redetermination filing. See further discussion within "Regulatory Assets and Regulatory Liabilities - Fuel and purchased power cost recovery - Entergy Arkansas - Energy Cost Recovery Rider" above. In April 2025 the APSC approved Entergy Arkansas’s proposal to include the remaining balance in its energy cost recovery rider effective with the first billing cycle of April 2025 and the withdrawal of the Grand Gulf credit rider after all credits have been issued.

Filings with the LPSC (Entergy Louisiana)

Retail Rates - Electric

2023 Formula Rate Plan Filing

As discussed in the Form 10-K, in August 2024, pursuant to the global stipulated settlement agreement, Entergy Louisiana filed its formula rate plan evaluation report for its 2023 calendar year operations. Consistent with the global stipulated settlement agreement, the filing reflected a 9.7% allowed return on common equity with a bandwidth of 40 basis points above and below the midpoint. For the 2023 test year, however, the bandwidth provisions of the formula rate plan are temporarily suspended and, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana implemented the September 2024 formula rate plan rate adjustments effective with the first billing cycle of September 2024. In January 2025, Entergy Louisiana and the LPSC filed a joint report indicating that no disputed issues remained in the proceeding and requesting that the LPSC issue an order accepting Entergy Louisiana’s evaluation report and, ultimately, resolving this matter. In March 2025 the LPSC issued an order accepting the evaluation report.

In December 2024, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed an interim rate adjustment for the 2023 test year reflecting the return of $25.1 million of refunds from the System Energy settlement with the LPSC to customers from January through August 2025. In February 2025, pursuant to the terms of the global stipulated settlement agreement, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting the divestiture of Entergy Louisiana’s share of Grand Gulf capacity and energy, which was effective as of January 1, 2025. The second interim rate adjustment also reflected a revenue increase of $17.8 million for the recovery of Hurricane Francine costs as approved by the LPSC (on an interim basis). The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the Hurricane Francine proceeding in “Storm Cost Recovery Filings with Retail Regulators – Entergy Louisiana – Hurricane Francine” below. See Note 8 to the financial statements in the Form 10-K for discussion of Entergy Louisiana’s divestiture from the Unit Power Sales Agreement.

Additional Generation and Transmission Resources

As discussed in the Form 10-K, in October 2024, Entergy Louisiana filed an application with the LPSC seeking approval of a variety of generation and transmission resources proposed in connection with establishing service to a new data center to be developed by a subsidiary of Meta Platforms, Inc. in north Louisiana, for which an electric service agreement has been executed. The filing requests LPSC certification of three new combined cycle combustion turbine generation resources totaling 2,262 MW, each of which will be enabled for future carbon capture and storage, a new 500 kV transmission line, and 500 kV substation upgrades. The application also requests approval to implement a corporate sustainability rider applicable to the new customer. The corporate sustainability rider contemplates the new customer contributing to the costs of the future addition of 1,500 MW of new solar and energy storage resources, agreements involving carbon capture and storage at Entergy Louisiana’s existing Lake Charles Power Station, and potential future wind and nuclear resources. Entergy Louisiana anticipates funding the incremental cost to serve the customer through direct financial contributions from the customer and the revenues it expects to earn under the electric service agreement. The electric service agreement also contains provisions for termination payments that will help ensure that there is no harm to Entergy Louisiana and its customers in the event
of early termination. A directive was issued at the LPSC’s November 2024 meeting for the matter to be decided by October 2025. In February 2025 intervenors filed a motion asking the LPSC to deny Entergy Louisiana’s requested exemption from the LPSC’s order addressing competitive solicitation procedures and further asking the LPSC to dismiss the application. The ALJ issued an order denying the motion to dismiss the application and deferring the LPSC’s consideration of the motion regarding the competitive solicitation procedures until the hearing. In March 2025 the same intervenors filed a motion requesting the LPSC to require the customer and its parent company to be joined as parties to the proceeding or dismiss the application. In April 2025 the ALJ issued an order denying the March 2025 motion, and the moving parties filed a motion asking the LPSC to review and reverse the ALJ’s decision. In April 2025 the LPSC staff and intervenors filed direct testimony. The LPSC staff’s testimony discusses the significant projected benefits associated with the data center project and also recommends that the LPSC impose certain conditions on its approval, including a condition that would require, under specified circumstances, certain sharing of net revenues from service to the project with Entergy Louisiana’s other customers. The LPSC staff also recommends that the LPSC deny approval of the corporate sustainability rider terms providing for the customer to supply funding toward the cost of installing carbon capture and storage infrastructure at Entergy Louisiana’s Lake Charles Power Station. The Louisiana Energy Users Group and other intervenors recommended that the LPSC require various changes to the terms of the electric service agreement with the customer that would shift additional risk and cost to the customer rather than Entergy Louisiana’s broader customer base. Certain intervenors also challenged approval on the basis that Entergy Louisiana did not conduct a request for proposals to procure the proposed generation resources to serve the customer’s project; these intervenors also advocate that Entergy Louisiana be required to procure more renewable generation and evaluate transmission alternatives rather than proceeding with development of all of the proposed new generation resources. Entergy Louisiana’s rebuttal testimony is due in May 2025, and a hearing is set for July 2025.

Filings with the MPSC (Entergy Mississippi)

Retail Rates

2025 Formula Rate Plan Filing

In February 2025, Entergy Mississippi submitted its formula rate plan 2025 test year filing and 2024 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2024 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2025 calendar year to also be within the formula rate plan bandwidth. The 2025 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2024 look-back filing compared actual 2024 results to the approved benchmark return on rate base and reflected no change in formula rate plan revenues, although Entergy Mississippi proposes to adjust interim rates by $135 thousand to reflect two outside-the-bandwidth changes: (1) the completion of Entergy Mississippi’s return to customers of credits under its restructuring credit rider; and (2) a true-up of demand side management costs. A final order is expected in second quarter 2025.

Interim Facilities Rate Adjustments

In May 2024, Entergy Mississippi received approval from the MPSC for formula rate plan revisions that were necessary for Entergy Mississippi to comply with state legislation passed in January 2024. The legislation allows Entergy Mississippi to make interim rate adjustments to recover the non-fuel related annual ownership cost of certain facilities that directly or indirectly provide service to customers who own certain data processing center projects as specified in the legislation. Entergy Mississippi filed the first of its annual interim facilities rate adjustment reports in May 2024 to recover approximately $8.7 million of these costs over a six-month period with rates effective beginning in July 2024. Entergy Mississippi filed its second interim facilities rate adjustment report in November 2024 to recover approximately $46.7 million of these costs over a 12-month period with rates effective beginning in January 2025. In February 2025, Entergy Mississippi filed a true-up interim facilities rate adjustment report to the initial annual interim facilities rate adjustment report filed in May 2024, reflecting the recovery of an
additional approximately $1.0 million of costs over a 12-month period with rates effective with the first billing cycle of April 2025.

Filings with the City Council (Entergy New Orleans)

Retail Rates

2025 Formula Rate Plan Filing

In April 2025, Entergy New Orleans submitted to the City Council its formula rate plan 2024 test year filing. The 2024 evaluation report produced an electric earned return on equity of 10.98% and a gas earned return on equity of 8.96% compared to the authorized return on equity for each of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million and no change in gas rates. The decrease in electric rates is driven by the realignment of regulatory liabilities into the formula from a separate rate mechanism, partially offset by the cost of known and measurable electric capital additions. The filing also commences the previously authorized recovery of certain regulatory costs and requests a revenue-neutral recovery to offset a proposed reduction in bill payment late fees. Taking into account these proposed adjustments, the filing presents a decrease in authorized electric revenues of $8.6 million and an increase in authorized gas revenues of $0.5 million. The filing is subject to a 75-day review period, followed by a 25-day period to resolve any disputes among the parties. For any disputed rate adjustments, however, the City Council would set a procedural schedule to resolve. Resulting rates will be effective with the first billing cycle of September 2025 pursuant to the formula rate plan tariff.

Filings with the PUCT and Texas Cities (Entergy Texas)

Retail Rates

Distribution Cost Recovery Factor (DCRF) Rider

In April 2025, Entergy Texas filed with the PUCT a request to amend its DCRF rider. The proposed rider is designed to collect from Entergy Texas’s retail customers approximately $77.8 million annually, or $29.3 million in incremental annual revenues beyond Entergy Texas’s currently effective DCRF rider based on its capital invested in distribution between July 1, 2024 and December 31, 2024, including distribution-related restoration costs associated with Hurricane Beryl.

Transmission Cost Recovery Factor (TCRF) Rider

As discussed in the Form 10-K, in October 2024, Entergy Texas filed with the PUCT a request to amend its TCRF rider, which was previously reset to zero in June 2023 as a result of the 2022 base rate case. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $9.7 million annually based on its capital invested in transmission between January 1, 2022 and June 30, 2024 and changes in other transmission charges. In April 2025 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 7, 2025.

Entergy Arkansas Opportunity Sales Proceeding

As discussed in the Form 10-K, in September 2020, Entergy Arkansas filed a complaint in the U.S. District Court for the Eastern District of Arkansas challenging the APSC’s denial of recovery of $135 million of payments to other Utility operating companies in December 2018 relating to off-system sales of electricity from 2002-2009, as ordered by the FERC. The complaint also involved a challenge to the $13.7 million, plus interest, of related refunds ordered by the APSC and paid by Entergy Arkansas in August 2020. The trial was held in February 2023.
In March 2024 the U.S. District Court for the Eastern District of Arkansas issued a judgment in favor of the APSC and against Entergy Arkansas. In March 2024 Entergy Arkansas filed a notice of appeal and a motion to expedite oral arguments with the United States Court of Appeals for the Eighth Circuit and the court granted the motion to expedite. As a result of the adverse decision by the U.S. District Court for the Eastern District of Arkansas, Entergy Arkansas concluded that it could no longer support the recognition of its $131.8 million regulatory asset reflecting the previously-expected recovery of a portion of the costs at issue in the opportunity sales proceeding and recorded a $131.8 million ($99.1 million net-of-tax) charge to earnings in first quarter 2024. In December 2024 the United States Court of Appeals for the Eighth Circuit affirmed the decision of the U.S. District Court for the Eastern District of Arkansas, and Entergy Arkansas filed a petition for rehearing en banc. In January 2025 the United States Court of Appeals for the Eighth Circuit denied Entergy Arkansas’s petition. In April 2025, Entergy Arkansas filed a petition for certiorari with the United States Supreme Court.

MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding

See Note 2 to the financial statements in the Form 10-K for discussion of the MSS-4 replacement tariff net operating loss carryforward proceeding.

The MSS-4 replacement tariff, a tariff governing the sales of energy and capacity among the Utility operating companies, includes protocols that provide for the disclosure of cost inputs, an opportunity for informal discovery procedures, and a challenge process. In April 2025, pursuant to such protocols, the City Council filed with the FERC a formal challenge relating to Entergy Services’ inclusion and allocation of net operating loss carryforward accumulated deferred income taxes in the MSS-4 replacement tariff rates charged to Entergy New Orleans’s monthly bills for calendar year 2023. Entergy Services plans to file a response to the formal challenge by the May 2025 deadline.

Complaints Against System Energy

See Note 2 to the financial statements in the Form 10-K for information regarding pending complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. The following is an update to that discussion.

Grand Gulf Sale-leaseback Renewal Complaint and Uncertain Tax Position Rate Base Issue

As discussed in the Form 10-K, in February 2023, System Energy submitted a tariff compliance filing with the FERC to clarify that, consistent with the releases provided in the June 2022 MPSC settlement, Entergy Mississippi would continue to be charged for its allocation of the sale-leaseback renewal costs under the Unit Power Sales Agreement. In March 2023 the MPSC filed a protest to System Energy’s tariff compliance filing. The MPSC argued that the settlement did not specifically address post-settlement sale-leaseback renewal costs and that the sale-leaseback renewal costs may not be recovered under the Unit Power Sales Agreement. In February 2025, System Energy and the MPSC resolved their dispute concerning the sale-leaseback renewal costs. As a result, the MPSC withdrew its protest at the FERC on System Energy’s tariff compliance filing. Entergy Mississippi will continue to pay the allocated sale-leaseback renewal costs of approximately $5.7 million annually and there are no refunds due for prior periods. In March 2025, System Energy filed a status report with the FERC explaining that the dispute is resolved.
Storm Cost Recovery Filings with Retail Regulators

See Note 2 to the financial statements in the Form 10-K for discussion regarding storm cost recovery filings. The following is an update to that discussion.

Entergy Louisiana

Hurricane Francine

In September 2024, Hurricane Francine caused damage to the areas served by Entergy Louisiana. The storm resulted in widespread power outages, primarily due to damage to distribution infrastructure as a result of strong winds and heavy rain, and the loss of sales during the power outages.

In December 2024, and subsequently amended in an errata filed in February 2025, Entergy Louisiana submitted an application to the LPSC seeking a determination that approximately $183.6 million in storm restoration costs associated with Hurricane Francine were reasonable and necessary and, therefore, eligible for recovery from customers, as well as approval to recover approximately $3.6 million in certain carrying costs from customers. In February 2025, Entergy Louisiana filed a second interim rate adjustment for the 2023 test year reflecting a revenue increase of $17.8 million from funds approved by the LPSC (on an interim basis) for Hurricane Francine recovery costs. The second interim rate adjustment was implemented with the first billing cycle of March 2025. See further discussion of the 2023 formula rate plan filing above. Also in February 2025, Entergy Louisiana withdrew $33.5 million from its funded storm reserves. In March 2025 a status conference was held in which a procedural schedule was established including a hearing in November 2025.

Equity Forward Sale Agreements

In March 2025, Entergy marketed an equity offering of 17.8 million shares of Entergy Corporation common stock. In lieu of issuing equity at the time of the offering, Entergy entered into forward sale agreements with several forward counterparties. No amounts have been or will be recorded on Entergy’s balance sheet with respect to the equity offering until settlements of the forward sale agreements occur. The forward sale agreements require Entergy to, at its election on or prior to September 30, 2026, either (1) physically settle the transactions by issuing the total of 17.8 million shares of its common stock to the forward counterparties in exchange for net proceeds at the then-applicable forward sale price specified by the agreements (initially $81.87 per share) or (2) net settle the transactions in whole or in part through the delivery or receipt of cash or shares. The forward sale price is subject to adjustment on a daily basis based on a floating interest rate factor and will decrease by other fixed amounts specified in the agreements.

Until settlement of the forward sale agreements, earnings per share dilution resulting from the agreements, if any, will be determined under the treasury stock method. Share dilution occurs when the average market price of Entergy’s common stock is higher than the average forward sales price. If Entergy had elected to net share settle the forward sale agreements as of March 31, 2025, Entergy would have been required to deliver 0.7 million shares.

Treasury Stock

During the three months ended March 31, 2025, Entergy Corporation reissued 1,193,693 shares of its previously repurchased common stock to satisfy stock option exercises, vesting of shares of restricted stock, and
other stock-based awards.  Entergy Corporation did not repurchase any of its common stock during the three months ended March 31, 2025.

Retained Earnings

Until settlement of the forward sale agreements discussed below in “Equity Distribution Program” and “Equity Forward Sale Agreements,” earnings per share dilution resulting from the agreements, if any, is determined under the treasury stock method. Share dilution occurs when the average market price of Entergy Corporation’s common stock is higher than the average forward sales price. The calculation of diluted earnings per share excluded 185,897 shares for the three months ended March 31, 2025 and 3,820,510 shares for the three months ended March 31, 2024 under forward sale agreements outstanding because their effect would have been antidilutive.

Equity Forward Sale Agreements

In March 2025, Entergy marketed an equity offering of 17.8 million shares of Entergy Corporation common stock. In lieu of issuing equity at the time of the offering, Entergy entered into forward sale agreements with several forward counterparties. No amounts have been or will be recorded on Entergy’s balance sheet with respect to the equity offering until settlements of the forward sale agreements occur. The forward sale agreements require Entergy to, at its election on or prior to September 30, 2026, either (1) physically settle the transactions by issuing the total of 17.8 million shares of its common stock to the forward counterparties in exchange for net proceeds at the then-applicable forward sale price specified by the agreements (initially $81.87 per share) or (2) net settle the transactions in whole or in part through the delivery or receipt of cash or shares. The forward sale price is subject to adjustment on a daily basis based on a floating interest rate factor and will decrease by other fixed amounts specified in the agreements.

Until settlement of the forward sale agreements, earnings per share dilution resulting from the agreements, if any, will be determined under the treasury stock method. Share dilution occurs when the average market price of Entergy’s common stock is higher than the average forward sales price. If Entergy had elected to net share settle the forward sale agreements as of March 31, 2025, Entergy would have been required to deliver 0.7 million shares.

Share-Based Payment Arrangement [Text Block] STOCK-BASED COMPENSATION (Entergy Corporation)
Entergy grants stock and stock-based awards, which are described more fully in Note 12 to the financial statements in the Form 10-K.  Awards under Entergy’s plans generally vest over three years.

Stock Options

In February 2025 the Board approved and Entergy granted long-term incentive awards in the form of options on 366,136 shares of its common stock under the 2019 Omnibus Incentive Plan with a fair value of $17.43 per option.  As of March 31, 2025, there were options on 3,176,358 shares of common stock outstanding with a weighted-average exercise price of $56.58.  The intrinsic value, which has no effect on net income, of the outstanding stock options is calculated by the positive difference between the weighted-average exercise price of the stock options granted and Entergy Corporation’s common stock price as of March 31, 2025.  The aggregate intrinsic value of the stock options outstanding as of March 31, 2025 was $91.8 million.

Other Equity Awards

In February 2025 the Board approved and Entergy granted long-term incentive awards in the form of 510,009 restricted stock awards and 187,036 performance units under the 2019 Omnibus Incentive Plan.  The restricted stock awards were made effective on February 6, 2025 and were valued at $82.79 per share, which was the closing price of Entergy Corporation’s common stock on the grant date.  Shares of restricted stock have the same dividend and voting rights as other common stock, are considered issued and outstanding shares of Entergy
upon vesting, and are expensed ratably over the three-year vesting period. One-third of the restricted stock awards and accrued dividends will vest upon each anniversary of the grant date.

The performance units represent the value of, and are settled with, one share of Entergy Corporation common stock at the end of the three-year performance period, plus dividends accrued during the performance period on the number of performance units earned. To emphasize the importance of environmental stewardship, specifically of carbon-free generation and resilience, an environmental achievement measure was selected as one of the performance measures for the 2025-2027 performance period. For the 2025-2027 performance period, performance will be measured based eighty percent on relative total shareholder return and twenty percent on the environmental achievement measure.  The performance units were granted on February 6, 2025 and eighty percent were valued at $115.13 per share based on various factors, primarily market conditions; and twenty percent were valued at $82.79 per share, the closing price of Entergy Corporation’s common stock on the grant date.  Performance units have the same dividend and voting rights as other common stock, are considered issued and outstanding shares of Entergy upon vesting, and are expensed ratably over the three-year vesting period, and compensation cost for the portion of the award based on the selected environmental achievement measure will be adjusted based on the number of units that ultimately vest. See Note 12 to the financial statements in the Form 10-K for a description of the Long-Term Performance Unit Program.

Registrant Subsidiaries

Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas each has one operating and reportable segment, an integrated utility business which includes the generation, transmission, and distribution of electric power; and operation of a small natural gas distribution business at each of Entergy Louisiana and Entergy New Orleans. System Energy has one operating and reportable segment, which is an electricity generation business. Each of the Registrant Subsidiaries’ operations are managed on an integrated basis by that company because of the substantial effect of cost-based rates and regulatory oversight on the business process, cost structures, and operating results. All segment financial information for the Registrant Subsidiaries is as reported on the respective financial statements for each of the Registrant Subsidiaries.

Derivative Instruments and Hedging Activities Disclosure [Text Block] RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy)
Market Risk

In the normal course of business, Entergy is exposed to a number of market risks.  Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument.  All financial and commodity-related instruments, including derivatives, are subject to market risk
including commodity price risk, equity price, and interest rate risk.  Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel.

The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation.  To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers.

Derivatives

Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments.

Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps as of March 31, 2025 is 7 months for Entergy Mississippi. The total volume of natural gas swaps outstanding as of March 31, 2025 is 12,246,850 MMBtu for Entergy and Entergy Mississippi. As of March 31, 2025, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps. Credit support for these natural gas swaps is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral.

During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of March 31, 2025 is 24,226 GWh for Entergy, including 5,865 GWh for Entergy Arkansas, 10,036 GWh for Entergy Louisiana, 3,781 GWh for Entergy Mississippi, 1,001 GWh for Entergy New Orleans, and 3,501 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of March 31, 2025 and December 31, 2024. No letters of credit were posted with MISO to cover financial transmission rights exposure as of March 31, 2025. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024.

Fair Values

The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling.  Considerable judgment is required in developing the estimates of fair value.  Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange.  Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments.

Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market
participants at the date of measurement.  Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value.  The inputs can be readily observable, corroborated by market data, or generally unobservable.  Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value.

Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value.  The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs.

The three levels of the fair value hierarchy are:

•Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.  Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets.  Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase.

•Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date.  Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads.  Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value.  Level 2 inputs include the following:

–quoted prices for similar assets or liabilities in active markets;
–quoted prices for identical assets or liabilities in inactive markets;
–inputs other than quoted prices that are observable for the asset or liability; or
–inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 2 consists primarily of individually-owned debt instruments and gas swaps valued using observable inputs.

•Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources.  These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability.  Level 3 consists primarily of financial transmission rights.

The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices.  They are classified as Level 3 assets and liabilities.  The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight.  The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer.  The Accounting group reports to the Chief Accounting Officer.

The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024.  The assessment
of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels.

Derivative Instruments and Hedging Activities Disclosure [Text Block] RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy)
Market Risk

In the normal course of business, Entergy is exposed to a number of market risks.  Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument.  All financial and commodity-related instruments, including derivatives, are subject to market risk
including commodity price risk, equity price, and interest rate risk.  Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel.

The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation.  To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers.

Derivatives

Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments.

Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps as of March 31, 2025 is 7 months for Entergy Mississippi. The total volume of natural gas swaps outstanding as of March 31, 2025 is 12,246,850 MMBtu for Entergy and Entergy Mississippi. As of March 31, 2025, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps. Credit support for these natural gas swaps is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral.

During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of March 31, 2025 is 24,226 GWh for Entergy, including 5,865 GWh for Entergy Arkansas, 10,036 GWh for Entergy Louisiana, 3,781 GWh for Entergy Mississippi, 1,001 GWh for Entergy New Orleans, and 3,501 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of March 31, 2025 and December 31, 2024. No letters of credit were posted with MISO to cover financial transmission rights exposure as of March 31, 2025. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024.

Fair Values

The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling.  Considerable judgment is required in developing the estimates of fair value.  Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange.  Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments.

Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market
participants at the date of measurement.  Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value.  The inputs can be readily observable, corroborated by market data, or generally unobservable.  Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value.

Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value.  The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs.

The three levels of the fair value hierarchy are:

•Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.  Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets.  Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase.

•Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date.  Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads.  Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value.  Level 2 inputs include the following:

–quoted prices for similar assets or liabilities in active markets;
–quoted prices for identical assets or liabilities in inactive markets;
–inputs other than quoted prices that are observable for the asset or liability; or
–inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 2 consists primarily of individually-owned debt instruments and gas swaps valued using observable inputs.

•Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources.  These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability.  Level 3 consists primarily of financial transmission rights.

The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices.  They are classified as Level 3 assets and liabilities.  The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight.  The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer.  The Accounting group reports to the Chief Accounting Officer.

The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024.  The assessment
of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels.

The maximum length of time over which Entergy has executed natural gas swaps as of March 31, 2025 is 7 months for Entergy Mississippi. The total volume of natural gas swaps outstanding as of March 31, 2025 is 12,246,850 MMBtu for Entergy and Entergy Mississippi. As of March 31, 2025, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps. Credit support for these natural gas swaps is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral.

During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of March 31, 2025 is 24,226 GWh for Entergy, including 5,865 GWh for Entergy Arkansas, 10,036 GWh for Entergy Louisiana, 3,781 GWh for Entergy Mississippi, 1,001 GWh for Entergy New Orleans, and 3,501 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of March 31, 2025 and December 31, 2024. No letters of credit were posted with MISO to cover financial transmission rights exposure as of March 31, 2025. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024.

Fair Values

The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling.  Considerable judgment is required in developing the estimates of fair value.  Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange.  Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments.

Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market
participants at the date of measurement.  Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value.  The inputs can be readily observable, corroborated by market data, or generally unobservable.  Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value.

Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value.  The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs.

The three levels of the fair value hierarchy are:

•Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.  Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets.  Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase.

•Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date.  Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads.  Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value.  Level 2 inputs include the following:

–quoted prices for similar assets or liabilities in active markets;
–quoted prices for identical assets or liabilities in inactive markets;
–inputs other than quoted prices that are observable for the asset or liability; or
–inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 2 consists primarily of individually-owned debt instruments and gas swaps valued using observable inputs.

•Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources.  These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability.  Level 3 consists primarily of financial transmission rights.

The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices.  They are classified as Level 3 assets and liabilities.  The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight.  The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer.  The Accounting group reports to the Chief Accounting Officer.

The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024.  The assessment
of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels.

Derivative Instruments and Hedging Activities Disclosure [Text Block] RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy)
Market Risk

In the normal course of business, Entergy is exposed to a number of market risks.  Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument.  All financial and commodity-related instruments, including derivatives, are subject to market risk
including commodity price risk, equity price, and interest rate risk.  Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel.

The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation.  To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers.

Derivatives

Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments.

Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps as of March 31, 2025 is 7 months for Entergy Mississippi. The total volume of natural gas swaps outstanding as of March 31, 2025 is 12,246,850 MMBtu for Entergy and Entergy Mississippi. As of March 31, 2025, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps. Credit support for these natural gas swaps is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral.

During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of March 31, 2025 is 24,226 GWh for Entergy, including 5,865 GWh for Entergy Arkansas, 10,036 GWh for Entergy Louisiana, 3,781 GWh for Entergy Mississippi, 1,001 GWh for Entergy New Orleans, and 3,501 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of March 31, 2025 and December 31, 2024. No letters of credit were posted with MISO to cover financial transmission rights exposure as of March 31, 2025. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024.

The fair values of Entergy’s derivative instruments not designated as hedging instruments on the consolidated balance sheets as of March 31, 2025 and December 31, 2024 are shown in the table below.  Certain investments, including those not designated as hedging instruments, are subject to master netting agreements and

Fair Values

The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling.  Considerable judgment is required in developing the estimates of fair value.  Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange.  Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments.

Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market
participants at the date of measurement.  Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value.  The inputs can be readily observable, corroborated by market data, or generally unobservable.  Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value.

Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value.  The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs.

The three levels of the fair value hierarchy are:

•Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.  Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets.  Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase.

•Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date.  Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads.  Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value.  Level 2 inputs include the following:

–quoted prices for similar assets or liabilities in active markets;
–quoted prices for identical assets or liabilities in inactive markets;
–inputs other than quoted prices that are observable for the asset or liability; or
–inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 2 consists primarily of individually-owned debt instruments and gas swaps valued using observable inputs.

•Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources.  These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability.  Level 3 consists primarily of financial transmission rights.

The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices.  They are classified as Level 3 assets and liabilities.  The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight.  The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer.  The Accounting group reports to the Chief Accounting Officer.

The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024.  The assessment
of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels.

Derivative Instruments and Hedging Activities Disclosure [Text Block] RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy)
Market Risk

In the normal course of business, Entergy is exposed to a number of market risks.  Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument.  All financial and commodity-related instruments, including derivatives, are subject to market risk
including commodity price risk, equity price, and interest rate risk.  Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel.

The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation.  To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers.

Derivatives

Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments.

Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps as of March 31, 2025 is 7 months for Entergy Mississippi. The total volume of natural gas swaps outstanding as of March 31, 2025 is 12,246,850 MMBtu for Entergy and Entergy Mississippi. As of March 31, 2025, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps. Credit support for these natural gas swaps is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral.

During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of March 31, 2025 is 24,226 GWh for Entergy, including 5,865 GWh for Entergy Arkansas, 10,036 GWh for Entergy Louisiana, 3,781 GWh for Entergy Mississippi, 1,001 GWh for Entergy New Orleans, and 3,501 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of March 31, 2025 and December 31, 2024. No letters of credit were posted with MISO to cover financial transmission rights exposure as of March 31, 2025. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024.

(b)Due to regulatory treatment, the changes in the estimated fair value of financial transmission rights for the Utility operating companies are recorded through purchased power expense and then such amounts are simultaneously reversed and recorded as an offsetting regulatory asset or liability.  The gains or losses recorded as purchased power expense when the financial transmission rights for the Utility operating companies are settled are recovered or refunded through fuel cost recovery mechanisms.

Fair Values

The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling.  Considerable judgment is required in developing the estimates of fair value.  Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange.  Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments.

Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market
participants at the date of measurement.  Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value.  The inputs can be readily observable, corroborated by market data, or generally unobservable.  Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value.

Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value.  The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs.

The three levels of the fair value hierarchy are:

•Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.  Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets.  Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase.

•Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date.  Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads.  Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value.  Level 2 inputs include the following:

–quoted prices for similar assets or liabilities in active markets;
–quoted prices for identical assets or liabilities in inactive markets;
–inputs other than quoted prices that are observable for the asset or liability; or
–inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 2 consists primarily of individually-owned debt instruments and gas swaps valued using observable inputs.

•Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources.  These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability.  Level 3 consists primarily of financial transmission rights.

The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices.  They are classified as Level 3 assets and liabilities.  The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight.  The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer.  The Accounting group reports to the Chief Accounting Officer.

The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024.  The assessment
of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels.

Derivative Instruments and Hedging Activities Disclosure [Text Block] RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy)
Market Risk

In the normal course of business, Entergy is exposed to a number of market risks.  Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument.  All financial and commodity-related instruments, including derivatives, are subject to market risk
including commodity price risk, equity price, and interest rate risk.  Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel.

The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation.  To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers.

Derivatives

Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments.

Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps as of March 31, 2025 is 7 months for Entergy Mississippi. The total volume of natural gas swaps outstanding as of March 31, 2025 is 12,246,850 MMBtu for Entergy and Entergy Mississippi. As of March 31, 2025, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps. Credit support for these natural gas swaps is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral.

During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of March 31, 2025 is 24,226 GWh for Entergy, including 5,865 GWh for Entergy Arkansas, 10,036 GWh for Entergy Louisiana, 3,781 GWh for Entergy Mississippi, 1,001 GWh for Entergy New Orleans, and 3,501 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of March 31, 2025 and December 31, 2024. No letters of credit were posted with MISO to cover financial transmission rights exposure as of March 31, 2025. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024.

Fair Values

The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling.  Considerable judgment is required in developing the estimates of fair value.  Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange.  Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments.

Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market
participants at the date of measurement.  Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value.  The inputs can be readily observable, corroborated by market data, or generally unobservable.  Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value.

Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value.  The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs.

The three levels of the fair value hierarchy are:

•Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.  Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets.  Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase.

•Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date.  Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads.  Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value.  Level 2 inputs include the following:

–quoted prices for similar assets or liabilities in active markets;
–quoted prices for identical assets or liabilities in inactive markets;
–inputs other than quoted prices that are observable for the asset or liability; or
–inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 2 consists primarily of individually-owned debt instruments and gas swaps valued using observable inputs.

•Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources.  These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability.  Level 3 consists primarily of financial transmission rights.

The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices.  They are classified as Level 3 assets and liabilities.  The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight.  The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer.  The Accounting group reports to the Chief Accounting Officer.

The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024.  The assessment
of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels.

Derivative Instruments and Hedging Activities Disclosure [Text Block] RISK MANAGEMENT AND FAIR VALUES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy)
Market Risk

In the normal course of business, Entergy is exposed to a number of market risks.  Market risk is the potential loss that Entergy may incur as a result of changes in the market or fair value of a particular commodity or instrument.  All financial and commodity-related instruments, including derivatives, are subject to market risk
including commodity price risk, equity price, and interest rate risk.  Entergy uses derivatives primarily to mitigate commodity price risk associated with the price of fuel.

The Utility has limited exposure to the effects of market risk because it operates primarily under cost-based rate regulation.  To the extent approved by their retail regulators, the Utility operating companies use commodity and financial instruments to hedge the exposure to price volatility inherent in their purchased power, fuel, and gas purchased for resale costs, that are recovered from customers.

Derivatives

Entergy designates a significant portion of its derivative instruments as normal purchase/normal sale transactions due to their physical settlement provisions, including power purchase and sales agreements, fuel purchase agreements, and capacity contracts. Certain derivative instruments do not qualify for designation as normal purchase/normal sale transactions due to their financial settlement provisions. See further discussion below regarding the accounting for these derivative instruments.

Entergy manages fuel price volatility for its Louisiana jurisdictions (Entergy Louisiana and Entergy New Orleans) and Entergy Mississippi through the purchase of natural gas swaps that financially settle against either the average Henry Hub Gas Daily prices or the NYMEX Henry Hub. These swaps are marked-to-market through fuel expense with offsetting regulatory assets or liabilities. All benefits or costs of the program are recorded in fuel costs. The notional volumes of these swaps are based on a portion of projected annual exposure to gas price volatility for electric generation at Entergy Louisiana and Entergy Mississippi and projected winter purchases for gas distribution at Entergy New Orleans. The maximum length of time over which Entergy has executed natural gas swaps as of March 31, 2025 is 7 months for Entergy Mississippi. The total volume of natural gas swaps outstanding as of March 31, 2025 is 12,246,850 MMBtu for Entergy and Entergy Mississippi. As of March 31, 2025, Entergy Louisiana and Entergy New Orleans had no outstanding natural gas swaps. Credit support for these natural gas swaps is covered by master agreements that do not require Entergy to provide collateral based on mark-to-market value, but do carry adequate assurance language that may lead to requests for collateral.

During the second quarter 2024, Entergy participated in the annual financial transmission rights auction process for the MISO planning year of June 1, 2024 through May 31, 2025. Financial transmission rights are derivative instruments that represent economic hedges of future congestion charges that will be incurred in serving Entergy’s customer load. They are not designated as hedging instruments. Entergy initially records financial transmission rights at their estimated fair value and subsequently adjusts the carrying value to their estimated fair value at the end of each accounting period prior to settlement. Unrealized gains or losses on financial transmission rights held by the non-utility operations are included in operating revenues. The Utility operating companies recognize regulatory liabilities or assets for unrealized gains or losses on financial transmission rights. The total volume of financial transmission rights outstanding as of March 31, 2025 is 24,226 GWh for Entergy, including 5,865 GWh for Entergy Arkansas, 10,036 GWh for Entergy Louisiana, 3,781 GWh for Entergy Mississippi, 1,001 GWh for Entergy New Orleans, and 3,501 GWh for Entergy Texas. Credit support for financial transmission rights held by the Utility operating companies is covered by cash and/or letters of credit issued by each Utility operating company as required by MISO. Credit support for financial transmission rights held by Entergy’s non-utility operations business is covered by cash. No cash or letters of credit were required to be posted for financial transmission rights exposure for the non-utility operations business as of March 31, 2025 and December 31, 2024. No letters of credit were posted with MISO to cover financial transmission rights exposure as of March 31, 2025. Letters of credit posted with MISO covered the financial transmission rights exposure for Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, and Entergy Texas as of December 31, 2024.

Fair Values

The estimated fair values of Entergy’s financial instruments and derivatives are determined using historical prices, bid prices, market quotes, and financial modeling.  Considerable judgment is required in developing the estimates of fair value.  Therefore, estimates are not necessarily indicative of the amounts that Entergy could realize in a current market exchange.  Gains or losses realized on financial instruments are reflected in future rates and therefore do not affect net income. Entergy considers the carrying amounts of most financial instruments classified as current assets and liabilities to be a reasonable estimate of their fair value because of the short maturity of these instruments.

Accounting standards define fair value as an exit price, or the price that would be received to sell an asset or the amount that would be paid to transfer a liability in an orderly transaction between knowledgeable market
participants at the date of measurement.  Entergy and the Registrant Subsidiaries use assumptions or market input data that market participants would use in pricing assets or liabilities at fair value.  The inputs can be readily observable, corroborated by market data, or generally unobservable.  Entergy and the Registrant Subsidiaries endeavor to use the best available information to determine fair value.

Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value.  The hierarchy establishes the highest priority for unadjusted market quotes in an active market for the identical asset or liability and the lowest priority for unobservable inputs.

The three levels of the fair value hierarchy are:

•Level 1 - Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.  Level 1 primarily consists of individually owned common stocks, cash equivalents (temporary cash investments, securitization recovery trust account, and escrow accounts), debt instruments, and gas swaps traded on exchanges with active markets.  Cash equivalents includes all unrestricted highly liquid debt instruments with an original or remaining maturity of three months or less at the date of purchase.

•Level 2 - Level 2 inputs are inputs other than quoted prices included in Level 1 that are, either directly or indirectly, observable for the asset or liability at the measurement date.  Assets are valued based on prices derived by independent third parties that use inputs such as benchmark yields, reported trades, broker/dealer quotes, and issuer spreads.  Prices are reviewed and can be challenged with the independent parties and/or overridden by Entergy if it is believed such would be more reflective of fair value.  Level 2 inputs include the following:

–quoted prices for similar assets or liabilities in active markets;
–quoted prices for identical assets or liabilities in inactive markets;
–inputs other than quoted prices that are observable for the asset or liability; or
–inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 2 consists primarily of individually-owned debt instruments and gas swaps valued using observable inputs.

•Level 3 - Level 3 inputs are pricing inputs that are generally less observable or unobservable from objective sources.  These inputs are used with internally developed methodologies to produce management’s best estimate of fair value for the asset or liability.  Level 3 consists primarily of financial transmission rights.

The values of financial transmission rights are based on unobservable inputs, including estimates of congestion costs in MISO between applicable generation and load pricing nodes based on the 50th percentile of historical prices.  They are classified as Level 3 assets and liabilities.  The valuations of these assets and liabilities are performed by the Office of Corporate Risk Oversight.  The values are calculated internally and verified against the data published by MISO. Entergy’s Accounting group reviews these valuations for reasonableness, with the assistance of others within the organization with knowledge of the various inputs and assumptions used in the valuation. The Office of Corporate Risk Oversight reports to the Vice President and Treasurer.  The Accounting group reports to the Chief Accounting Officer.

The following tables set forth, by level within the fair value hierarchy, Entergy’s assets and liabilities that are accounted for at fair value on a recurring basis as of March 31, 2025 and December 31, 2024.  The assessment
of the significance of a particular input to a fair value measurement requires judgment and may affect placement within the fair value hierarchy levels.

Decommissioning Trust Funds
 3 Months Ended

Decommissioning Trust Fund [Text Block] DECOMMISSIONING TRUST FUNDS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, and System Energy)
The NRC requires certain of the Utility operating companies and System Energy to maintain nuclear decommissioning trusts to fund the costs of decommissioning ANO 1 and 2, River Bend, Waterford 3, and Grand Gulf. Entergy’s nuclear decommissioning trust funds invest in equity securities, fixed-rate debt securities, and cash and cash equivalents.

Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets.  For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Generally, Entergy records gains and losses on its debt and equity securities using the specific identification method to determine the cost basis of its securities.

The unrealized gains/(losses) recognized during the three months ended March 31, 2025 on equity securities still held as of March 31, 2025 were $190 million. The equity securities are generally held in funds that are designed to approximate or somewhat exceed the return of the Standard & Poor’s 500 Index.  A relatively small percentage of the equity securities are held in funds that are designed to approximate or somewhat exceed the return of the Wilshire 4500 Index. The debt securities are generally held in individual government and credit issuances.

As of March 31, 2025 and December 31, 2024, there were no deferred taxes on unrealized gains/(losses). The amortized cost of available-for-sale debt securities was $2,138 million as of March 31, 2025 and $2,121 million as of December 31, 2024.  As of March 31, 2025, available-for-sale debt securities had an average coupon rate of approximately 4.12%, an average duration of approximately 6.35 years, and an average maturity of approximately 10.94 years.

Decommissioning Trust Fund [Text Block] DECOMMISSIONING TRUST FUNDS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, and System Energy)
The NRC requires certain of the Utility operating companies and System Energy to maintain nuclear decommissioning trusts to fund the costs of decommissioning ANO 1 and 2, River Bend, Waterford 3, and Grand Gulf. Entergy’s nuclear decommissioning trust funds invest in equity securities, fixed-rate debt securities, and cash and cash equivalents.

Entergy records decommissioning trust funds on the balance sheet at their fair value. Because of the ability of the Registrant Subsidiaries to recover decommissioning costs in rates and in accordance with the regulatory treatment for decommissioning trust funds, for unrealized gains/(losses) on investment securities, the Registrant Subsidiaries record an offsetting amount in other regulatory liabilities/assets.  For the 30% interest in River Bend formerly owned by Cajun, Entergy Louisiana records an offsetting amount in other long-term liabilities on the consolidated balance sheets of Entergy and Entergy Louisiana for the unrealized trust earnings not currently expected to be needed to decommission the plant. Generally, Entergy records gains and losses on its debt and equity securities using the specific identification method to determine the cost basis of its securities.

The unrealized gains/(losses) recognized during the three months ended March 31, 2025 on equity securities still held as of March 31, 2025 were $190 million.

See Note 14 to the financial statements in the Form 10-K for information regarding the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses. The following are updates to that discussion.

Natural Gas Distribution Businesses

On October 28, 2023, Entergy New Orleans and Entergy Louisiana each entered into separate purchase and sale agreements with respect to the sale of their respective regulated natural gas local distribution company businesses to two separate affiliates of Bernhard Capital Partners Management LP. Under the purchase and sale agreements, Entergy New Orleans has agreed to sell its regulated natural gas local distribution company business serving customers in the Parish of Orleans, Louisiana, and Entergy Louisiana has agreed to sell its regulated natural gas local distribution company business serving customers in the Parish of East Baton Rouge, Louisiana. The Entergy Louisiana and Entergy New Orleans natural gas distribution businesses are reflected in Entergy’s Utility reportable segment and in the respective single reportable segment for each of Entergy Louisiana and Entergy New Orleans.
Required regulatory approval was received from the LPSC and the City Council in August 2024 and December 2024, respectively. In February 2025 the Metropolitan Council of the Parish of East Baton Rouge approved the proposed sale of the Entergy Louisiana natural gas distribution business and also approved the assignment of the parish franchise from Entergy Louisiana to Delta Capital Gas Company, LLC (a Bernhard Capital Partners Management LP affiliate).

The transactions have two phases: (1) an “Initial Phase” prior to regulatory approvals in connection with both transactions; and (2) a “Second Phase” following regulatory approvals in connection with both transactions to the extent that certain conditions are satisfied or, where permissible, waived for both transactions. As described above, the transactions have received all required regulatory approvals, and the Second Phase commenced on March 5, 2025.

Under the purchase and sale agreements, the closing of the transactions is not required to occur earlier than six months following the initiation of the Second Phase; however, the parties may agree to close prior to that date. The purchase and sale agreements may be terminated by either party in the event the closing has not occurred prior to October 28, 2025. Neither transaction is subject to a financing condition for the applicable buyer.
As of March 31, 2025 and December 31, 2024, the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses met the criteria to be classified as held for sale. As of March 31, 2025, neither Entergy Louisiana nor Entergy New Orleans has recognized any write downs of the natural gas distribution business assets as a result of their classification as held for sale, as neither sale is expected to result in a loss. The assets and liabilities of the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses classified as held for sale on Entergy’s, Entergy Louisiana’s, and Entergy New Orleans’s consolidated balance sheets as of March 31, 2025 and December 31, 2024 included the following amounts:

(b)    Included within other current liabilities on the respective consolidated balance sheets.
(c)    Included within other non-current liabilities on the respective consolidated balance sheets.

Entergy Louisiana and Entergy New Orleans will continue to recognize depreciation on the natural gas distribution businesses assets since they will continue to receive revenues through utility customer rates until the closing of the transaction, and because the final purchase price for the natural gas distribution businesses will be adjusted by an amount equal to that depreciation, among other adjustments.
The pre-tax income for the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses, excluding interest and corporate allocations, included in Entergy’s, Entergy Louisiana’s, and Entergy New Orleans’s consolidated income statements for the three months ended March 31, 2025 and 2024 is as follows:

See Note 14 to the financial statements in the Form 10-K for information regarding the planned sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses. The following are updates to that discussion.

Natural Gas Distribution Businesses

On October 28, 2023, Entergy New Orleans and Entergy Louisiana each entered into separate purchase and sale agreements with respect to the sale of their respective regulated natural gas local distribution company businesses to two separate affiliates of Bernhard Capital Partners Management LP. Under the purchase and sale agreements, Entergy New Orleans has agreed to sell its regulated natural gas local distribution company business serving customers in the Parish of Orleans, Louisiana, and Entergy Louisiana has agreed to sell its regulated natural gas local distribution company business serving customers in the Parish of East Baton Rouge, Louisiana. The Entergy Louisiana and Entergy New Orleans natural gas distribution businesses are reflected in Entergy’s Utility reportable segment and in the respective single reportable segment for each of Entergy Louisiana and Entergy New Orleans.
Required regulatory approval was received from the LPSC and the City Council in August 2024 and December 2024, respectively. In February 2025 the Metropolitan Council of the Parish of East Baton Rouge approved the proposed sale of the Entergy Louisiana natural gas distribution business and also approved the assignment of the parish franchise from Entergy Louisiana to Delta Capital Gas Company, LLC (a Bernhard Capital Partners Management LP affiliate).

The transactions have two phases: (1) an “Initial Phase” prior to regulatory approvals in connection with both transactions; and (2) a “Second Phase” following regulatory approvals in connection with both transactions to the extent that certain conditions are satisfied or, where permissible, waived for both transactions. As described above, the transactions have received all required regulatory approvals, and the Second Phase commenced on March 5, 2025.

Under the purchase and sale agreements, the closing of the transactions is not required to occur earlier than six months following the initiation of the Second Phase; however, the parties may agree to close prior to that date. The purchase and sale agreements may be terminated by either party in the event the closing has not occurred prior to October 28, 2025. Neither transaction is subject to a financing condition for the applicable buyer.
As of March 31, 2025 and December 31, 2024, the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses met the criteria to be classified as held for sale. As of March 31, 2025, neither Entergy Louisiana nor Entergy New Orleans has recognized any write downs of the natural gas distribution business assets as a result of their classification as held for sale, as neither sale is expected to result in a loss. The assets and liabilities of the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses classified as held for sale on Entergy’s, Entergy Louisiana’s, and Entergy New Orleans’s consolidated balance sheets as of March 31, 2025 and December 31, 2024 included the following amounts:

(c)Other Utility revenues include the occasional sales of inventory, alternative revenue programs, provisions for revenue subject to refund, and late fees.
(d)Other revenues include the sale of electric power and capacity to wholesale customers, day-ahead sales of energy in a market administered by an ISO, and operation and management services fees.
