RATE AND REGULATORY MATTERS (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy)

Regulatory Assets and Regulatory Liabilities

See Note 2 to the financial statements in the Form 10-K for information regarding regulatory assets and regulatory liabilities in the Utility business presented on the balance sheets of Entergy and the Registrant Subsidiaries.  The following are updates to that discussion.

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 LPSC accepted the report in June 2025.

Entergy Texas

As discussed in the Form 10-K, in September 2024, Entergy Texas filed an application with the PUCT to reconcile its fuel and purchased power costs for the period from April 2022 through March 2024. During the reconciliation period, Entergy Texas incurred approximately $1.6 billion in eligible fuel and purchased power expenses to generate and purchase electricity to serve its customers, net of certain revenues credited to such expenses and other adjustments. Entergy Texas’s cumulative under-recovery balance for the reconciliation period was approximately $30 million, including interest, which Entergy Texas requested authority to carry over as part of the cumulative fuel balance for the subsequent reconciliation period beginning April 2024. In November 2024 the PUCT referred the proceeding to the State Office of Administrative Hearings. In March 2025, Texas Industrial Energy Consumers, an intervenor, filed testimony regarding the recovery of capacity costs for a certain power purchase agreement, arguing the capacity costs should be imputed and treated as non-reconcilable fuel expense, recovered in Entergy Texas’s base rates. In April 2025 the PUCT staff filed testimony and later in April 2025, Entergy Texas filed rebuttal testimony. In May 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a request for a paper hearing and to cancel the oral hearing on the merits previously scheduled for later in May 2025. In June 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a joint motion to abate the proceeding to give the parties to the proceeding additional time to finalize a settlement.

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

2025 Formula Rate Plan Filing

In July 2025, Entergy Arkansas filed with the APSC its 2025 formula rate plan filing to set its formula rate for the 2026 calendar year.  The filing contained an evaluation of Entergy Arkansas’s earnings for the 2026 projected year and a netting adjustment for the 2024 historical year.  The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2026 projected year was 8.45% resulting in a revenue deficiency of $68.9 million.  The earned rate of return on common equity for the 2024 historical year was 7.71% resulting in a $48.8 million netting adjustment.  The total proposed revenue change for the 2026 projected year and 2024 historical year netting adjustment is $117.7 million.   By operation of the formula rate plan, Entergy Arkansas’s recovery of the revenue requirement is subject to a four percent annual revenue constraint.  Because Entergy Arkansas’s revenue requirement in this filing exceeded the constraint, the resulting increase was limited to $92.3 million. Entergy Arkansas proposed a procedural schedule that includes a hearing in November 2025 and requests an APSC order in December 2025.

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 had been issued. Credits to retail customers were completed in second quarter 2025, and the Grand Gulf credit rider was subsequently withdrawn.

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 approved by the LPSC also in August 2024, 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 were 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.

2024 Formula Rate Plan Filing

In May 2025, Entergy Louisiana filed its formula rate plan evaluation report for its 2024 calendar year operations. Consistent with the global stipulated settlement agreement approved by the LPSC in August 2024, 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 test year 2024, however, any earnings above the allowed return on common equity are to be returned to customers through a credit, pursuant to the terms of the global stipulated settlement agreement. The 2024 test year evaluation produced an earned return on common equity of 9.98%, which is within the approved formula rate plan bandwidth, but above the allowed return on common equity, resulting in a customer credit of $31.9 million to be returned to customers during September and October 2025.

Other changes in formula rate plan revenue are driven by higher nuclear depreciation rates, additions to transmission and distribution plant in service reflected through the transmission recovery mechanism and distribution recovery mechanism, and the expiration of customer credits related to the LPSC’s order, offset by increased customer credits resulting from an increase in net MISO revenues reflected through the MISO cost recovery mechanism and the reduction in the Louisiana corporate income tax rate effective January 1, 2025, reflected through the tax adjustment mechanism, as discussed below. Excluding the customer credit for earnings above the authorized return on common equity discussed above, the net result of these changes on an annualized basis is a $2 million increase in formula rate plan revenue.

As noted above, the 2024 evaluation report included the effects of the change in Louisiana state tax law that reduced the corporate income tax rate to a flat 5.5% (from the then-current highest marginal rate of 7.5%) effective January 1, 2025. As such, the 2024 evaluation report reflected the calculation of current and deferred income tax expenses as well as the revaluation of accumulated deferred income taxes based on the income tax laws currently in effect. The 2024 evaluation report proposes that the rate effects associated with the revaluation of accumulated deferred income taxes, including the collection of any net accumulated deferred income tax deficiency and any related effects on rate base, should be reflected in the tax adjustment mechanism consistent with the treatment of similar Tax Cuts and Jobs Act and prior state tax change-related impacts. The effects of the change in tax law on Entergy Louisiana’s authorized return on rate base are also reflected in the 2024 evaluation report consistent with the treatment cited above, including a credit in the extraordinary cost change mechanism for the prospective change in Entergy Louisiana’s authorized return and a credit within the tax adjustment mechanism for over-collection of income tax expense through August 2025.

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 February 2025, Entergy Louisiana filed supplemental testimony with the LPSC stating that the third combined cycle combustion turbine resource presented in the October 2024 application would be sited at Entergy Louisiana’s Waterford site in Killona, Louisiana, alongside existing Entergy Louisiana generation resources. The testimony also notes that Entergy Louisiana is negotiating with the customer in response to the customer’s request to increase the load associated with its project in north Louisiana. The testimony indicates further that the additional load can be served without additional generation capacity beyond what was presented in the October 2024 application, but that additional transmission facilities, which will be funded directly by the customer, are needed to serve this additional load.

In April 2025 and May 2025 the LPSC staff and certain intervenors each filed their direct testimony and cross-answering testimony, respectively. The LPSC staff’s testimony discussed the significant projected benefits associated with the data center project; however, both the LPSC staff and such intervenors also identified purported risks associated with constructing the requested resources based on the terms and conditions under which the customer would be taking service. Both the LPSC staff and such intervenors also recommended that the LPSC impose certain conditions on its approval which, if adopted, would support approval of Entergy Louisiana’s application. The LPSC staff’s recommendations included 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 recommended 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 advocated 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 May 2025, Entergy Louisiana filed its rebuttal testimony responding to the direct and cross-answering testimony of the LPSC staff and intervenors. The rebuttal testimony expressed support for or no opposition to the LPSC’s adoption of certain of the proposed recommendations and identified why other proposed recommendations should not be adopted. In addition, the rebuttal testimony stated that the negotiations related to the increase in the load amount for the customer’s project had concluded and that a rider to the electric service agreement reflecting this increase had been executed. In advance of the July 2025 hearing, Entergy Louisiana reached a settlement agreement with the LPSC staff and three separate intervenors. The hearing concluded and the matter is currently under consideration by the ALJ.

COVID-19 Orders

As discussed in the Form 10-K, in April 2020 the LPSC issued an order authorizing utilities to record as a regulatory asset expenses incurred from the suspension of disconnections and collection of late fees imposed by LPSC orders associated with the COVID-19 pandemic. In April 2023, Entergy Louisiana filed an application proposing to utilize approximately $1.6 billion in certain low interest debt to generate earnings to apply toward the reduction of the COVID-19 regulatory asset, as well as to conduct additional outside right-of-way vegetation management activities and fund the minor storm reserve account. In that filing, Entergy Louisiana proposed to delay repayment of certain shorter-term first mortgage bonds that were issued to finance storm restoration costs until the costs could be securitized, and to invest the funds that otherwise would be used to repay those bonds in the money pool to take advantage of the spread between prevailing interest rates on investments in the money pool and the interest rates on the bonds. The LPSC approved Entergy Louisiana’s requested relief in June 2023. In November 2024, Entergy Louisiana submitted a filing to the LPSC requesting that the LPSC review Entergy Louisiana’s computation of the COVID-19 regulatory asset as well as Entergy Louisiana’s proposal to offset the regulatory asset against the net interest earned on the short-term debt funds, resulting in no increased costs to customers. At the time of the filing, Entergy Louisiana had a regulatory asset of $47.8 million for costs associated

with the COVID-19 pandemic. As of June 30, 2025, Entergy Louisiana had a regulatory liability of $48.9 million for the deferred earnings related to the approximately $1.6 billion in low interest debt, which had been fully repaid by August 2024. In granting Entergy Louisiana’s requested relief in June 2023, the LPSC ordered that any amount of earnings exceeding the amount of the COVID-19 regulatory asset be transferred to Entergy Louisiana’s storm reserve escrow account. In May 2025 the LPSC staff filed direct testimony finding that Entergy Louisiana had complied with the relevant orders and recommending approval of the requested treatment. In June 2025, Entergy Louisiana and the LPSC staff filed a joint motion requesting a hearing for the admission of an uncontested stipulated settlement agreement in the matter. A settlement hearing took place in July 2025 and Entergy Louisiana expects the settlement to be considered at an upcoming meeting of the LPSC. The settlement terms provide for LPSC approval of Entergy Louisiana’s calculation of the COVID-19 regulatory assets and Entergy Louisiana’s proposal to offset the regulatory asset as described above and as proposed in Entergy Louisiana’s November 2024 filing.

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 also to be within the formula rate plan bandwidth. The 2025 test year filing showed 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 proposed 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.

In June 2025, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2025 test year filing, with the exception of immaterial adjustments to certain operation and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2025, resulting in no change in formula rate plan revenues for 2025. Pursuant to the stipulation, Entergy Mississippi’s 2024 look-back filing reflected an earned return on rate base of 7.55%, which also resulted in no change in formula rate plan revenues for 2024. In addition, the stipulation included the recovery of the two outside-the-bandwidth changes discussed above as well as the ratemaking treatment of customer contributions (deferred revenue and prepaid contributions in aid of construction). In June 2025 the MPSC approved the joint stipulation with rates effective in July 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% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million. 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. The City Council’s advisors issued their report in July 2025 seeking a reduction in Entergy New Orleans’s requested electric formula rate plan revenues of approximately $7.2 million due to certain proposed cost realignments and disallowances, of which $4.1 million is associated with Entergy New Orleans’s proposed implementation, on a revenue neutral basis, of a proposed reduction in customer late fees. The City Council’s advisors also proposed rate mitigation in the amount of $4.4 million through offsets to the formula rate plan funded by certain regulatory liabilities. The City Council’s advisors’ report began a 35-day period to resolve any disputes among the parties regarding the formula rate plan. For any disputed rate adjustments, 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 amended rider was 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 then-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. In June 2025 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective on June 25, 2025.

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. In June 2025 the United States Supreme Court denied Entergy Arkansas’s petition for certiorari.

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. In May 2025, Entergy Services filed a response to the formal challenge and is awaiting a response from the FERC.

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 are updates 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. In April 2025 the FERC accepted System Energy’s tariff compliance filing.

System Energy Settlement with the LPSC

As discussed in the Form 10-K, in 2024, System Energy reached a settlement with the LPSC to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC (including all docketed proceedings resolved by the MPSC, the APSC, and the City Council settlements) and associated with System Energy’s past implementation of the Unit Power Sales Agreement. In compliance with the settlement, in May 2025, System Energy, Entergy Louisiana, and Entergy Mississippi submitted the following filings with the FERC: (1) a Federal Power Act Section 203 application seeking approval for the permanent divestiture by Entergy Louisiana to Entergy Mississippi of its rights to capacity and energy from Grand Gulf; and (2) a Federal Power Act Section 205 application seeking approval to modify the entitlement percentages of the remaining purchasers under the Unit Power Sales Agreement in connection with the foregoing divestiture. In July 2025, the FERC issued an order accepting the Federal Power Act Section 205 application to remove Entergy Louisiana as a party to the Unit Power Sales Agreement. As a result of the order, the Unit Power Sales Agreement entitlement percentages of the remaining purchasers will be permanently modified to exclude Entergy Louisiana, to be effective beginning October 2025. The FERC also issued an order dismissing the Federal Power Act Section 203 application based on lack of jurisdiction.

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 June 2025 the LPSC staff filed direct testimony. The LPSC staff recommends approval of Entergy Louisiana’s as-requested storm restoration costs with the exception of approximately $10.6 million, comprised primarily of estimates of mutual assistance invoices that have not yet been received at the time of filing and that ultimately exceeded the actual amounts invoiced, as well as certain incentive compensation, and $1.8 million associated with certain carrying costs. Entergy Louisiana’s rebuttal testimony is due in August 2025 and a hearing is scheduled for 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 LPSC accepted the report in June 2025.

Entergy Texas

As discussed in the Form 10-K, in September 2024, Entergy Texas filed an application with the PUCT to reconcile its fuel and purchased power costs for the period from April 2022 through March 2024. During the reconciliation period, Entergy Texas incurred approximately $1.6 billion in eligible fuel and purchased power expenses to generate and purchase electricity to serve its customers, net of certain revenues credited to such expenses and other adjustments. Entergy Texas’s cumulative under-recovery balance for the reconciliation period was approximately $30 million, including interest, which Entergy Texas requested authority to carry over as part of the cumulative fuel balance for the subsequent reconciliation period beginning April 2024. In November 2024 the PUCT referred the proceeding to the State Office of Administrative Hearings. In March 2025, Texas Industrial Energy Consumers, an intervenor, filed testimony regarding the recovery of capacity costs for a certain power purchase agreement, arguing the capacity costs should be imputed and treated as non-reconcilable fuel expense, recovered in Entergy Texas’s base rates. In April 2025 the PUCT staff filed testimony and later in April 2025, Entergy Texas filed rebuttal testimony. In May 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a request for a paper hearing and to cancel the oral hearing on the merits previously scheduled for later in May 2025. In June 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a joint motion to abate the proceeding to give the parties to the proceeding additional time to finalize a settlement.

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

2025 Formula Rate Plan Filing

In July 2025, Entergy Arkansas filed with the APSC its 2025 formula rate plan filing to set its formula rate for the 2026 calendar year.  The filing contained an evaluation of Entergy Arkansas’s earnings for the 2026 projected year and a netting adjustment for the 2024 historical year.  The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2026 projected year was 8.45% resulting in a revenue deficiency of $68.9 million.  The earned rate of return on common equity for the 2024 historical year was 7.71% resulting in a $48.8 million netting adjustment.  The total proposed revenue change for the 2026 projected year and 2024 historical year netting adjustment is $117.7 million.   By operation of the formula rate plan, Entergy Arkansas’s recovery of the revenue requirement is subject to a four percent annual revenue constraint.  Because Entergy Arkansas’s revenue requirement in this filing exceeded the constraint, the resulting increase was limited to $92.3 million. Entergy Arkansas proposed a procedural schedule that includes a hearing in November 2025 and requests an APSC order in December 2025.

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 had been issued. Credits to retail customers were completed in second quarter 2025, and the Grand Gulf credit rider was subsequently withdrawn.

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 approved by the LPSC also in August 2024, 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 were 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.

2024 Formula Rate Plan Filing

In May 2025, Entergy Louisiana filed its formula rate plan evaluation report for its 2024 calendar year operations. Consistent with the global stipulated settlement agreement approved by the LPSC in August 2024, 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 test year 2024, however, any earnings above the allowed return on common equity are to be returned to customers through a credit, pursuant to the terms of the global stipulated settlement agreement. The 2024 test year evaluation produced an earned return on common equity of 9.98%, which is within the approved formula rate plan bandwidth, but above the allowed return on common equity, resulting in a customer credit of $31.9 million to be returned to customers during September and October 2025.

Other changes in formula rate plan revenue are driven by higher nuclear depreciation rates, additions to transmission and distribution plant in service reflected through the transmission recovery mechanism and distribution recovery mechanism, and the expiration of customer credits related to the LPSC’s order, offset by increased customer credits resulting from an increase in net MISO revenues reflected through the MISO cost recovery mechanism and the reduction in the Louisiana corporate income tax rate effective January 1, 2025, reflected through the tax adjustment mechanism, as discussed below. Excluding the customer credit for earnings above the authorized return on common equity discussed above, the net result of these changes on an annualized basis is a $2 million increase in formula rate plan revenue.

As noted above, the 2024 evaluation report included the effects of the change in Louisiana state tax law that reduced the corporate income tax rate to a flat 5.5% (from the then-current highest marginal rate of 7.5%) effective January 1, 2025. As such, the 2024 evaluation report reflected the calculation of current and deferred income tax expenses as well as the revaluation of accumulated deferred income taxes based on the income tax laws currently in effect. The 2024 evaluation report proposes that the rate effects associated with the revaluation of accumulated deferred income taxes, including the collection of any net accumulated deferred income tax deficiency and any related effects on rate base, should be reflected in the tax adjustment mechanism consistent with the treatment of similar Tax Cuts and Jobs Act and prior state tax change-related impacts. The effects of the change in tax law on Entergy Louisiana’s authorized return on rate base are also reflected in the 2024 evaluation report consistent with the treatment cited above, including a credit in the extraordinary cost change mechanism for the prospective change in Entergy Louisiana’s authorized return and a credit within the tax adjustment mechanism for over-collection of income tax expense through August 2025.

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 February 2025, Entergy Louisiana filed supplemental testimony with the LPSC stating that the third combined cycle combustion turbine resource presented in the October 2024 application would be sited at Entergy Louisiana’s Waterford site in Killona, Louisiana, alongside existing Entergy Louisiana generation resources. The testimony also notes that Entergy Louisiana is negotiating with the customer in response to the customer’s request to increase the load associated with its project in north Louisiana. The testimony indicates further that the additional load can be served without additional generation capacity beyond what was presented in the October 2024 application, but that additional transmission facilities, which will be funded directly by the customer, are needed to serve this additional load.

In April 2025 and May 2025 the LPSC staff and certain intervenors each filed their direct testimony and cross-answering testimony, respectively. The LPSC staff’s testimony discussed the significant projected benefits associated with the data center project; however, both the LPSC staff and such intervenors also identified purported risks associated with constructing the requested resources based on the terms and conditions under which the customer would be taking service. Both the LPSC staff and such intervenors also recommended that the LPSC impose certain conditions on its approval which, if adopted, would support approval of Entergy Louisiana’s application. The LPSC staff’s recommendations included 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 recommended 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 advocated 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 May 2025, Entergy Louisiana filed its rebuttal testimony responding to the direct and cross-answering testimony of the LPSC staff and intervenors. The rebuttal testimony expressed support for or no opposition to the LPSC’s adoption of certain of the proposed recommendations and identified why other proposed recommendations should not be adopted. In addition, the rebuttal testimony stated that the negotiations related to the increase in the load amount for the customer’s project had concluded and that a rider to the electric service agreement reflecting this increase had been executed. In advance of the July 2025 hearing, Entergy Louisiana reached a settlement agreement with the LPSC staff and three separate intervenors. The hearing concluded and the matter is currently under consideration by the ALJ.

COVID-19 Orders

As discussed in the Form 10-K, in April 2020 the LPSC issued an order authorizing utilities to record as a regulatory asset expenses incurred from the suspension of disconnections and collection of late fees imposed by LPSC orders associated with the COVID-19 pandemic. In April 2023, Entergy Louisiana filed an application proposing to utilize approximately $1.6 billion in certain low interest debt to generate earnings to apply toward the reduction of the COVID-19 regulatory asset, as well as to conduct additional outside right-of-way vegetation management activities and fund the minor storm reserve account. In that filing, Entergy Louisiana proposed to delay repayment of certain shorter-term first mortgage bonds that were issued to finance storm restoration costs until the costs could be securitized, and to invest the funds that otherwise would be used to repay those bonds in the money pool to take advantage of the spread between prevailing interest rates on investments in the money pool and the interest rates on the bonds. The LPSC approved Entergy Louisiana’s requested relief in June 2023. In November 2024, Entergy Louisiana submitted a filing to the LPSC requesting that the LPSC review Entergy Louisiana’s computation of the COVID-19 regulatory asset as well as Entergy Louisiana’s proposal to offset the regulatory asset against the net interest earned on the short-term debt funds, resulting in no increased costs to customers. At the time of the filing, Entergy Louisiana had a regulatory asset of $47.8 million for costs associated

with the COVID-19 pandemic. As of June 30, 2025, Entergy Louisiana had a regulatory liability of $48.9 million for the deferred earnings related to the approximately $1.6 billion in low interest debt, which had been fully repaid by August 2024. In granting Entergy Louisiana’s requested relief in June 2023, the LPSC ordered that any amount of earnings exceeding the amount of the COVID-19 regulatory asset be transferred to Entergy Louisiana’s storm reserve escrow account. In May 2025 the LPSC staff filed direct testimony finding that Entergy Louisiana had complied with the relevant orders and recommending approval of the requested treatment. In June 2025, Entergy Louisiana and the LPSC staff filed a joint motion requesting a hearing for the admission of an uncontested stipulated settlement agreement in the matter. A settlement hearing took place in July 2025 and Entergy Louisiana expects the settlement to be considered at an upcoming meeting of the LPSC. The settlement terms provide for LPSC approval of Entergy Louisiana’s calculation of the COVID-19 regulatory assets and Entergy Louisiana’s proposal to offset the regulatory asset as described above and as proposed in Entergy Louisiana’s November 2024 filing.

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 also to be within the formula rate plan bandwidth. The 2025 test year filing showed 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 proposed 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.

In June 2025, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2025 test year filing, with the exception of immaterial adjustments to certain operation and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2025, resulting in no change in formula rate plan revenues for 2025. Pursuant to the stipulation, Entergy Mississippi’s 2024 look-back filing reflected an earned return on rate base of 7.55%, which also resulted in no change in formula rate plan revenues for 2024. In addition, the stipulation included the recovery of the two outside-the-bandwidth changes discussed above as well as the ratemaking treatment of customer contributions (deferred revenue and prepaid contributions in aid of construction). In June 2025 the MPSC approved the joint stipulation with rates effective in July 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% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million. 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. The City Council’s advisors issued their report in July 2025 seeking a reduction in Entergy New Orleans’s requested electric formula rate plan revenues of approximately $7.2 million due to certain proposed cost realignments and disallowances, of which $4.1 million is associated with Entergy New Orleans’s proposed implementation, on a revenue neutral basis, of a proposed reduction in customer late fees. The City Council’s advisors also proposed rate mitigation in the amount of $4.4 million through offsets to the formula rate plan funded by certain regulatory liabilities. The City Council’s advisors’ report began a 35-day period to resolve any disputes among the parties regarding the formula rate plan. For any disputed rate adjustments, 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 amended rider was 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 then-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. In June 2025 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective on June 25, 2025.

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. In June 2025 the United States Supreme Court denied Entergy Arkansas’s petition for certiorari.

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. In May 2025, Entergy Services filed a response to the formal challenge and is awaiting a response from the FERC.

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 are updates 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. In April 2025 the FERC accepted System Energy’s tariff compliance filing.

System Energy Settlement with the LPSC

As discussed in the Form 10-K, in 2024, System Energy reached a settlement with the LPSC to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC (including all docketed proceedings resolved by the MPSC, the APSC, and the City Council settlements) and associated with System Energy’s past implementation of the Unit Power Sales Agreement. In compliance with the settlement, in May 2025, System Energy, Entergy Louisiana, and Entergy Mississippi submitted the following filings with the FERC: (1) a Federal Power Act Section 203 application seeking approval for the permanent divestiture by Entergy Louisiana to Entergy Mississippi of its rights to capacity and energy from Grand Gulf; and (2) a Federal Power Act Section 205 application seeking approval to modify the entitlement percentages of the remaining purchasers under the Unit Power Sales Agreement in connection with the foregoing divestiture. In July 2025, the FERC issued an order accepting the Federal Power Act Section 205 application to remove Entergy Louisiana as a party to the Unit Power Sales Agreement. As a result of the order, the Unit Power Sales Agreement entitlement percentages of the remaining purchasers will be permanently modified to exclude Entergy Louisiana, to be effective beginning October 2025. The FERC also issued an order dismissing the Federal Power Act Section 203 application based on lack of jurisdiction.

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 June 2025 the LPSC staff filed direct testimony. The LPSC staff recommends approval of Entergy Louisiana’s as-requested storm restoration costs with the exception of approximately $10.6 million, comprised primarily of estimates of mutual assistance invoices that have not yet been received at the time of filing and that ultimately exceeded the actual amounts invoiced, as well as certain incentive compensation, and $1.8 million associated with certain carrying costs. Entergy Louisiana’s rebuttal testimony is due in August 2025 and a hearing is scheduled for November 2025.

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.

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 LPSC accepted the report in June 2025.

Entergy Texas

As discussed in the Form 10-K, in September 2024, Entergy Texas filed an application with the PUCT to reconcile its fuel and purchased power costs for the period from April 2022 through March 2024. During the reconciliation period, Entergy Texas incurred approximately $1.6 billion in eligible fuel and purchased power expenses to generate and purchase electricity to serve its customers, net of certain revenues credited to such expenses and other adjustments. Entergy Texas’s cumulative under-recovery balance for the reconciliation period was approximately $30 million, including interest, which Entergy Texas requested authority to carry over as part of the cumulative fuel balance for the subsequent reconciliation period beginning April 2024. In November 2024 the PUCT referred the proceeding to the State Office of Administrative Hearings. In March 2025, Texas Industrial Energy Consumers, an intervenor, filed testimony regarding the recovery of capacity costs for a certain power purchase agreement, arguing the capacity costs should be imputed and treated as non-reconcilable fuel expense, recovered in Entergy Texas’s base rates. In April 2025 the PUCT staff filed testimony and later in April 2025, Entergy Texas filed rebuttal testimony. In May 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a request for a paper hearing and to cancel the oral hearing on the merits previously scheduled for later in May 2025. In June 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a joint motion to abate the proceeding to give the parties to the proceeding additional time to finalize a settlement.

Filings with the APSC (Entergy Arkansas)

Retail Rates

2025 Formula Rate Plan Filing

In July 2025, Entergy Arkansas filed with the APSC its 2025 formula rate plan filing to set its formula rate for the 2026 calendar year.  The filing contained an evaluation of Entergy Arkansas’s earnings for the 2026 projected year and a netting adjustment for the 2024 historical year.  The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2026 projected year was 8.45% resulting in a revenue deficiency of $68.9 million.  The earned rate of return on common equity for the 2024 historical year was 7.71% resulting in a $48.8 million netting adjustment.  The total proposed revenue change for the 2026 projected year and 2024 historical year netting adjustment is $117.7 million.   By operation of the formula rate plan, Entergy Arkansas’s recovery of the revenue requirement is subject to a four percent annual revenue constraint.  Because Entergy Arkansas’s revenue requirement in this filing exceeded the constraint, the resulting increase was limited to $92.3 million. Entergy Arkansas proposed a procedural schedule that includes a hearing in November 2025 and requests an APSC order in December 2025.

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 had been issued. Credits to retail customers were completed in second quarter 2025, and the Grand Gulf credit rider was subsequently withdrawn.

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 approved by the LPSC also in August 2024, 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 were 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.

2024 Formula Rate Plan Filing

In May 2025, Entergy Louisiana filed its formula rate plan evaluation report for its 2024 calendar year operations. Consistent with the global stipulated settlement agreement approved by the LPSC in August 2024, 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 test year 2024, however, any earnings above the allowed return on common equity are to be returned to customers through a credit, pursuant to the terms of the global stipulated settlement agreement. The 2024 test year evaluation produced an earned return on common equity of 9.98%, which is within the approved formula rate plan bandwidth, but above the allowed return on common equity, resulting in a customer credit of $31.9 million to be returned to customers during September and October 2025.

Other changes in formula rate plan revenue are driven by higher nuclear depreciation rates, additions to transmission and distribution plant in service reflected through the transmission recovery mechanism and distribution recovery mechanism, and the expiration of customer credits related to the LPSC’s order, offset by increased customer credits resulting from an increase in net MISO revenues reflected through the MISO cost recovery mechanism and the reduction in the Louisiana corporate income tax rate effective January 1, 2025, reflected through the tax adjustment mechanism, as discussed below. Excluding the customer credit for earnings above the authorized return on common equity discussed above, the net result of these changes on an annualized basis is a $2 million increase in formula rate plan revenue.

As noted above, the 2024 evaluation report included the effects of the change in Louisiana state tax law that reduced the corporate income tax rate to a flat 5.5% (from the then-current highest marginal rate of 7.5%) effective January 1, 2025. As such, the 2024 evaluation report reflected the calculation of current and deferred income tax expenses as well as the revaluation of accumulated deferred income taxes based on the income tax laws currently in effect. The 2024 evaluation report proposes that the rate effects associated with the revaluation of accumulated deferred income taxes, including the collection of any net accumulated deferred income tax deficiency and any related effects on rate base, should be reflected in the tax adjustment mechanism consistent with the treatment of similar Tax Cuts and Jobs Act and prior state tax change-related impacts. The effects of the change in tax law on Entergy Louisiana’s authorized return on rate base are also reflected in the 2024 evaluation report consistent with the treatment cited above, including a credit in the extraordinary cost change mechanism for the prospective change in Entergy Louisiana’s authorized return and a credit within the tax adjustment mechanism for over-collection of income tax expense through August 2025.

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 February 2025, Entergy Louisiana filed supplemental testimony with the LPSC stating that the third combined cycle combustion turbine resource presented in the October 2024 application would be sited at Entergy Louisiana’s Waterford site in Killona, Louisiana, alongside existing Entergy Louisiana generation resources. The testimony also notes that Entergy Louisiana is negotiating with the customer in response to the customer’s request to increase the load associated with its project in north Louisiana. The testimony indicates further that the additional load can be served without additional generation capacity beyond what was presented in the October 2024 application, but that additional transmission facilities, which will be funded directly by the customer, are needed to serve this additional load.

In April 2025 and May 2025 the LPSC staff and certain intervenors each filed their direct testimony and cross-answering testimony, respectively. The LPSC staff’s testimony discussed the significant projected benefits associated with the data center project; however, both the LPSC staff and such intervenors also identified purported risks associated with constructing the requested resources based on the terms and conditions under which the customer would be taking service. Both the LPSC staff and such intervenors also recommended that the LPSC impose certain conditions on its approval which, if adopted, would support approval of Entergy Louisiana’s application. The LPSC staff’s recommendations included 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 recommended 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 advocated 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 May 2025, Entergy Louisiana filed its rebuttal testimony responding to the direct and cross-answering testimony of the LPSC staff and intervenors. The rebuttal testimony expressed support for or no opposition to the LPSC’s adoption of certain of the proposed recommendations and identified why other proposed recommendations should not be adopted. In addition, the rebuttal testimony stated that the negotiations related to the increase in the load amount for the customer’s project had concluded and that a rider to the electric service agreement reflecting this increase had been executed. In advance of the July 2025 hearing, Entergy Louisiana reached a settlement agreement with the LPSC staff and three separate intervenors. The hearing concluded and the matter is currently under consideration by the ALJ.

COVID-19 Orders

As discussed in the Form 10-K, in April 2020 the LPSC issued an order authorizing utilities to record as a regulatory asset expenses incurred from the suspension of disconnections and collection of late fees imposed by LPSC orders associated with the COVID-19 pandemic. In April 2023, Entergy Louisiana filed an application proposing to utilize approximately $1.6 billion in certain low interest debt to generate earnings to apply toward the reduction of the COVID-19 regulatory asset, as well as to conduct additional outside right-of-way vegetation management activities and fund the minor storm reserve account. In that filing, Entergy Louisiana proposed to delay repayment of certain shorter-term first mortgage bonds that were issued to finance storm restoration costs until the costs could be securitized, and to invest the funds that otherwise would be used to repay those bonds in the money pool to take advantage of the spread between prevailing interest rates on investments in the money pool and the interest rates on the bonds. The LPSC approved Entergy Louisiana’s requested relief in June 2023. In November 2024, Entergy Louisiana submitted a filing to the LPSC requesting that the LPSC review Entergy Louisiana’s computation of the COVID-19 regulatory asset as well as Entergy Louisiana’s proposal to offset the regulatory asset against the net interest earned on the short-term debt funds, resulting in no increased costs to customers. At the time of the filing, Entergy Louisiana had a regulatory asset of $47.8 million for costs associated

with the COVID-19 pandemic. As of June 30, 2025, Entergy Louisiana had a regulatory liability of $48.9 million for the deferred earnings related to the approximately $1.6 billion in low interest debt, which had been fully repaid by August 2024. In granting Entergy Louisiana’s requested relief in June 2023, the LPSC ordered that any amount of earnings exceeding the amount of the COVID-19 regulatory asset be transferred to Entergy Louisiana’s storm reserve escrow account. In May 2025 the LPSC staff filed direct testimony finding that Entergy Louisiana had complied with the relevant orders and recommending approval of the requested treatment. In June 2025, Entergy Louisiana and the LPSC staff filed a joint motion requesting a hearing for the admission of an uncontested stipulated settlement agreement in the matter. A settlement hearing took place in July 2025 and Entergy Louisiana expects the settlement to be considered at an upcoming meeting of the LPSC. The settlement terms provide for LPSC approval of Entergy Louisiana’s calculation of the COVID-19 regulatory assets and Entergy Louisiana’s proposal to offset the regulatory asset as described above and as proposed in Entergy Louisiana’s November 2024 filing.

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 also to be within the formula rate plan bandwidth. The 2025 test year filing showed 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 proposed 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.

In June 2025, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2025 test year filing, with the exception of immaterial adjustments to certain operation and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2025, resulting in no change in formula rate plan revenues for 2025. Pursuant to the stipulation, Entergy Mississippi’s 2024 look-back filing reflected an earned return on rate base of 7.55%, which also resulted in no change in formula rate plan revenues for 2024. In addition, the stipulation included the recovery of the two outside-the-bandwidth changes discussed above as well as the ratemaking treatment of customer contributions (deferred revenue and prepaid contributions in aid of construction). In June 2025 the MPSC approved the joint stipulation with rates effective in July 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% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million. 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. The City Council’s advisors issued their report in July 2025 seeking a reduction in Entergy New Orleans’s requested electric formula rate plan revenues of approximately $7.2 million due to certain proposed cost realignments and disallowances, of which $4.1 million is associated with Entergy New Orleans’s proposed implementation, on a revenue neutral basis, of a proposed reduction in customer late fees. The City Council’s advisors also proposed rate mitigation in the amount of $4.4 million through offsets to the formula rate plan funded by certain regulatory liabilities. The City Council’s advisors’ report began a 35-day period to resolve any disputes among the parties regarding the formula rate plan. For any disputed rate adjustments, 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 amended rider was 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 then-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. In June 2025 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective on June 25, 2025.

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. In June 2025 the United States Supreme Court denied Entergy Arkansas’s petition for certiorari.

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. In May 2025, Entergy Services filed a response to the formal challenge and is awaiting a response from the FERC.

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 are updates 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. In April 2025 the FERC accepted System Energy’s tariff compliance filing.

System Energy Settlement with the LPSC

As discussed in the Form 10-K, in 2024, System Energy reached a settlement with the LPSC to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC (including all docketed proceedings resolved by the MPSC, the APSC, and the City Council settlements) and associated with System Energy’s past implementation of the Unit Power Sales Agreement. In compliance with the settlement, in May 2025, System Energy, Entergy Louisiana, and Entergy Mississippi submitted the following filings with the FERC: (1) a Federal Power Act Section 203 application seeking approval for the permanent divestiture by Entergy Louisiana to Entergy Mississippi of its rights to capacity and energy from Grand Gulf; and (2) a Federal Power Act Section 205 application seeking approval to modify the entitlement percentages of the remaining purchasers under the Unit Power Sales Agreement in connection with the foregoing divestiture. In July 2025, the FERC issued an order accepting the Federal Power Act Section 205 application to remove Entergy Louisiana as a party to the Unit Power Sales Agreement. As a result of the order, the Unit Power Sales Agreement entitlement percentages of the remaining purchasers will be permanently modified to exclude Entergy Louisiana, to be effective beginning October 2025. The FERC also issued an order dismissing the Federal Power Act Section 203 application based on lack of jurisdiction.

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 June 2025 the LPSC staff filed direct testimony. The LPSC staff recommends approval of Entergy Louisiana’s as-requested storm restoration costs with the exception of approximately $10.6 million, comprised primarily of estimates of mutual assistance invoices that have not yet been received at the time of filing and that ultimately exceeded the actual amounts invoiced, as well as certain incentive compensation, and $1.8 million associated with certain carrying costs. Entergy Louisiana’s rebuttal testimony is due in August 2025 and a hearing is scheduled for November 2025.

Regulatory Assets and Regulatory Liabilities

See Note 2 to the financial statements in the Form 10-K for information regarding regulatory assets and regulatory liabilities in the Utility business presented on the balance sheets of Entergy and the Registrant Subsidiaries.  The following are updates to that discussion.

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 LPSC accepted the report in June 2025.

Entergy Texas

As discussed in the Form 10-K, in September 2024, Entergy Texas filed an application with the PUCT to reconcile its fuel and purchased power costs for the period from April 2022 through March 2024. During the reconciliation period, Entergy Texas incurred approximately $1.6 billion in eligible fuel and purchased power expenses to generate and purchase electricity to serve its customers, net of certain revenues credited to such expenses and other adjustments. Entergy Texas’s cumulative under-recovery balance for the reconciliation period was approximately $30 million, including interest, which Entergy Texas requested authority to carry over as part of the cumulative fuel balance for the subsequent reconciliation period beginning April 2024. In November 2024 the PUCT referred the proceeding to the State Office of Administrative Hearings. In March 2025, Texas Industrial Energy Consumers, an intervenor, filed testimony regarding the recovery of capacity costs for a certain power purchase agreement, arguing the capacity costs should be imputed and treated as non-reconcilable fuel expense, recovered in Entergy Texas’s base rates. In April 2025 the PUCT staff filed testimony and later in April 2025, Entergy Texas filed rebuttal testimony. In May 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a request for a paper hearing and to cancel the oral hearing on the merits previously scheduled for later in May 2025. In June 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a joint motion to abate the proceeding to give the parties to the proceeding additional time to finalize a settlement.

Filings with the APSC (Entergy Arkansas)

Retail Rates

2025 Formula Rate Plan Filing

In July 2025, Entergy Arkansas filed with the APSC its 2025 formula rate plan filing to set its formula rate for the 2026 calendar year.  The filing contained an evaluation of Entergy Arkansas’s earnings for the 2026 projected year and a netting adjustment for the 2024 historical year.  The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2026 projected year was 8.45% resulting in a revenue deficiency of $68.9 million.  The earned rate of return on common equity for the 2024 historical year was 7.71% resulting in a $48.8 million netting adjustment.  The total proposed revenue change for the 2026 projected year and 2024 historical year netting adjustment is $117.7 million.   By operation of the formula rate plan, Entergy Arkansas’s recovery of the revenue requirement is subject to a four percent annual revenue constraint.  Because Entergy Arkansas’s revenue requirement in this filing exceeded the constraint, the resulting increase was limited to $92.3 million. Entergy Arkansas proposed a procedural schedule that includes a hearing in November 2025 and requests an APSC order in December 2025.

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 had been issued. Credits to retail customers were completed in second quarter 2025, and the Grand Gulf credit rider was subsequently withdrawn.

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 approved by the LPSC also in August 2024, 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 were 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.

2024 Formula Rate Plan Filing

In May 2025, Entergy Louisiana filed its formula rate plan evaluation report for its 2024 calendar year operations. Consistent with the global stipulated settlement agreement approved by the LPSC in August 2024, 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 test year 2024, however, any earnings above the allowed return on common equity are to be returned to customers through a credit, pursuant to the terms of the global stipulated settlement agreement. The 2024 test year evaluation produced an earned return on common equity of 9.98%, which is within the approved formula rate plan bandwidth, but above the allowed return on common equity, resulting in a customer credit of $31.9 million to be returned to customers during September and October 2025.

Other changes in formula rate plan revenue are driven by higher nuclear depreciation rates, additions to transmission and distribution plant in service reflected through the transmission recovery mechanism and distribution recovery mechanism, and the expiration of customer credits related to the LPSC’s order, offset by increased customer credits resulting from an increase in net MISO revenues reflected through the MISO cost recovery mechanism and the reduction in the Louisiana corporate income tax rate effective January 1, 2025, reflected through the tax adjustment mechanism, as discussed below. Excluding the customer credit for earnings above the authorized return on common equity discussed above, the net result of these changes on an annualized basis is a $2 million increase in formula rate plan revenue.

As noted above, the 2024 evaluation report included the effects of the change in Louisiana state tax law that reduced the corporate income tax rate to a flat 5.5% (from the then-current highest marginal rate of 7.5%) effective January 1, 2025. As such, the 2024 evaluation report reflected the calculation of current and deferred income tax expenses as well as the revaluation of accumulated deferred income taxes based on the income tax laws currently in effect. The 2024 evaluation report proposes that the rate effects associated with the revaluation of accumulated deferred income taxes, including the collection of any net accumulated deferred income tax deficiency and any related effects on rate base, should be reflected in the tax adjustment mechanism consistent with the treatment of similar Tax Cuts and Jobs Act and prior state tax change-related impacts. The effects of the change in tax law on Entergy Louisiana’s authorized return on rate base are also reflected in the 2024 evaluation report consistent with the treatment cited above, including a credit in the extraordinary cost change mechanism for the prospective change in Entergy Louisiana’s authorized return and a credit within the tax adjustment mechanism for over-collection of income tax expense through August 2025.

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 February 2025, Entergy Louisiana filed supplemental testimony with the LPSC stating that the third combined cycle combustion turbine resource presented in the October 2024 application would be sited at Entergy Louisiana’s Waterford site in Killona, Louisiana, alongside existing Entergy Louisiana generation resources. The testimony also notes that Entergy Louisiana is negotiating with the customer in response to the customer’s request to increase the load associated with its project in north Louisiana. The testimony indicates further that the additional load can be served without additional generation capacity beyond what was presented in the October 2024 application, but that additional transmission facilities, which will be funded directly by the customer, are needed to serve this additional load.

In April 2025 and May 2025 the LPSC staff and certain intervenors each filed their direct testimony and cross-answering testimony, respectively. The LPSC staff’s testimony discussed the significant projected benefits associated with the data center project; however, both the LPSC staff and such intervenors also identified purported risks associated with constructing the requested resources based on the terms and conditions under which the customer would be taking service. Both the LPSC staff and such intervenors also recommended that the LPSC impose certain conditions on its approval which, if adopted, would support approval of Entergy Louisiana’s application. The LPSC staff’s recommendations included 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 recommended 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 advocated 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 May 2025, Entergy Louisiana filed its rebuttal testimony responding to the direct and cross-answering testimony of the LPSC staff and intervenors. The rebuttal testimony expressed support for or no opposition to the LPSC’s adoption of certain of the proposed recommendations and identified why other proposed recommendations should not be adopted. In addition, the rebuttal testimony stated that the negotiations related to the increase in the load amount for the customer’s project had concluded and that a rider to the electric service agreement reflecting this increase had been executed. In advance of the July 2025 hearing, Entergy Louisiana reached a settlement agreement with the LPSC staff and three separate intervenors. The hearing concluded and the matter is currently under consideration by the ALJ.

COVID-19 Orders

As discussed in the Form 10-K, in April 2020 the LPSC issued an order authorizing utilities to record as a regulatory asset expenses incurred from the suspension of disconnections and collection of late fees imposed by LPSC orders associated with the COVID-19 pandemic. In April 2023, Entergy Louisiana filed an application proposing to utilize approximately $1.6 billion in certain low interest debt to generate earnings to apply toward the reduction of the COVID-19 regulatory asset, as well as to conduct additional outside right-of-way vegetation management activities and fund the minor storm reserve account. In that filing, Entergy Louisiana proposed to delay repayment of certain shorter-term first mortgage bonds that were issued to finance storm restoration costs until the costs could be securitized, and to invest the funds that otherwise would be used to repay those bonds in the money pool to take advantage of the spread between prevailing interest rates on investments in the money pool and the interest rates on the bonds. The LPSC approved Entergy Louisiana’s requested relief in June 2023. In November 2024, Entergy Louisiana submitted a filing to the LPSC requesting that the LPSC review Entergy Louisiana’s computation of the COVID-19 regulatory asset as well as Entergy Louisiana’s proposal to offset the regulatory asset against the net interest earned on the short-term debt funds, resulting in no increased costs to customers. At the time of the filing, Entergy Louisiana had a regulatory asset of $47.8 million for costs associated

with the COVID-19 pandemic. As of June 30, 2025, Entergy Louisiana had a regulatory liability of $48.9 million for the deferred earnings related to the approximately $1.6 billion in low interest debt, which had been fully repaid by August 2024. In granting Entergy Louisiana’s requested relief in June 2023, the LPSC ordered that any amount of earnings exceeding the amount of the COVID-19 regulatory asset be transferred to Entergy Louisiana’s storm reserve escrow account. In May 2025 the LPSC staff filed direct testimony finding that Entergy Louisiana had complied with the relevant orders and recommending approval of the requested treatment. In June 2025, Entergy Louisiana and the LPSC staff filed a joint motion requesting a hearing for the admission of an uncontested stipulated settlement agreement in the matter. A settlement hearing took place in July 2025 and Entergy Louisiana expects the settlement to be considered at an upcoming meeting of the LPSC. The settlement terms provide for LPSC approval of Entergy Louisiana’s calculation of the COVID-19 regulatory assets and Entergy Louisiana’s proposal to offset the regulatory asset as described above and as proposed in Entergy Louisiana’s November 2024 filing.

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 also to be within the formula rate plan bandwidth. The 2025 test year filing showed 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 proposed 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.

In June 2025, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2025 test year filing, with the exception of immaterial adjustments to certain operation and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2025, resulting in no change in formula rate plan revenues for 2025. Pursuant to the stipulation, Entergy Mississippi’s 2024 look-back filing reflected an earned return on rate base of 7.55%, which also resulted in no change in formula rate plan revenues for 2024. In addition, the stipulation included the recovery of the two outside-the-bandwidth changes discussed above as well as the ratemaking treatment of customer contributions (deferred revenue and prepaid contributions in aid of construction). In June 2025 the MPSC approved the joint stipulation with rates effective in July 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% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million. 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. The City Council’s advisors issued their report in July 2025 seeking a reduction in Entergy New Orleans’s requested electric formula rate plan revenues of approximately $7.2 million due to certain proposed cost realignments and disallowances, of which $4.1 million is associated with Entergy New Orleans’s proposed implementation, on a revenue neutral basis, of a proposed reduction in customer late fees. The City Council’s advisors also proposed rate mitigation in the amount of $4.4 million through offsets to the formula rate plan funded by certain regulatory liabilities. The City Council’s advisors’ report began a 35-day period to resolve any disputes among the parties regarding the formula rate plan. For any disputed rate adjustments, 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 amended rider was 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 then-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. In June 2025 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective on June 25, 2025.

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. In June 2025 the United States Supreme Court denied Entergy Arkansas’s petition for certiorari.

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. In May 2025, Entergy Services filed a response to the formal challenge and is awaiting a response from the FERC.

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 are updates 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. In April 2025 the FERC accepted System Energy’s tariff compliance filing.

System Energy Settlement with the LPSC

As discussed in the Form 10-K, in 2024, System Energy reached a settlement with the LPSC to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC (including all docketed proceedings resolved by the MPSC, the APSC, and the City Council settlements) and associated with System Energy’s past implementation of the Unit Power Sales Agreement. In compliance with the settlement, in May 2025, System Energy, Entergy Louisiana, and Entergy Mississippi submitted the following filings with the FERC: (1) a Federal Power Act Section 203 application seeking approval for the permanent divestiture by Entergy Louisiana to Entergy Mississippi of its rights to capacity and energy from Grand Gulf; and (2) a Federal Power Act Section 205 application seeking approval to modify the entitlement percentages of the remaining purchasers under the Unit Power Sales Agreement in connection with the foregoing divestiture. In July 2025, the FERC issued an order accepting the Federal Power Act Section 205 application to remove Entergy Louisiana as a party to the Unit Power Sales Agreement. As a result of the order, the Unit Power Sales Agreement entitlement percentages of the remaining purchasers will be permanently modified to exclude Entergy Louisiana, to be effective beginning October 2025. The FERC also issued an order dismissing the Federal Power Act Section 203 application based on lack of jurisdiction.

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 June 2025 the LPSC staff filed direct testimony. The LPSC staff recommends approval of Entergy Louisiana’s as-requested storm restoration costs with the exception of approximately $10.6 million, comprised primarily of estimates of mutual assistance invoices that have not yet been received at the time of filing and that ultimately exceeded the actual amounts invoiced, as well as certain incentive compensation, and $1.8 million associated with certain carrying costs. Entergy Louisiana’s rebuttal testimony is due in August 2025 and a hearing is scheduled for November 2025.

Regulatory Assets and Regulatory Liabilities

See Note 2 to the financial statements in the Form 10-K for information regarding regulatory assets and regulatory liabilities in the Utility business presented on the balance sheets of Entergy and the Registrant Subsidiaries.  The following are updates to that discussion.

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 LPSC accepted the report in June 2025.

Entergy Texas

As discussed in the Form 10-K, in September 2024, Entergy Texas filed an application with the PUCT to reconcile its fuel and purchased power costs for the period from April 2022 through March 2024. During the reconciliation period, Entergy Texas incurred approximately $1.6 billion in eligible fuel and purchased power expenses to generate and purchase electricity to serve its customers, net of certain revenues credited to such expenses and other adjustments. Entergy Texas’s cumulative under-recovery balance for the reconciliation period was approximately $30 million, including interest, which Entergy Texas requested authority to carry over as part of the cumulative fuel balance for the subsequent reconciliation period beginning April 2024. In November 2024 the PUCT referred the proceeding to the State Office of Administrative Hearings. In March 2025, Texas Industrial Energy Consumers, an intervenor, filed testimony regarding the recovery of capacity costs for a certain power purchase agreement, arguing the capacity costs should be imputed and treated as non-reconcilable fuel expense, recovered in Entergy Texas’s base rates. In April 2025 the PUCT staff filed testimony and later in April 2025, Entergy Texas filed rebuttal testimony. In May 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a request for a paper hearing and to cancel the oral hearing on the merits previously scheduled for later in May 2025. In June 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a joint motion to abate the proceeding to give the parties to the proceeding additional time to finalize a settlement.

Filings with the APSC (Entergy Arkansas)

Retail Rates

2025 Formula Rate Plan Filing

In July 2025, Entergy Arkansas filed with the APSC its 2025 formula rate plan filing to set its formula rate for the 2026 calendar year.  The filing contained an evaluation of Entergy Arkansas’s earnings for the 2026 projected year and a netting adjustment for the 2024 historical year.  The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2026 projected year was 8.45% resulting in a revenue deficiency of $68.9 million.  The earned rate of return on common equity for the 2024 historical year was 7.71% resulting in a $48.8 million netting adjustment.  The total proposed revenue change for the 2026 projected year and 2024 historical year netting adjustment is $117.7 million.   By operation of the formula rate plan, Entergy Arkansas’s recovery of the revenue requirement is subject to a four percent annual revenue constraint.  Because Entergy Arkansas’s revenue requirement in this filing exceeded the constraint, the resulting increase was limited to $92.3 million. Entergy Arkansas proposed a procedural schedule that includes a hearing in November 2025 and requests an APSC order in December 2025.

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 had been issued. Credits to retail customers were completed in second quarter 2025, and the Grand Gulf credit rider was subsequently withdrawn.

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 approved by the LPSC also in August 2024, 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 were 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.

2024 Formula Rate Plan Filing

In May 2025, Entergy Louisiana filed its formula rate plan evaluation report for its 2024 calendar year operations. Consistent with the global stipulated settlement agreement approved by the LPSC in August 2024, 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 test year 2024, however, any earnings above the allowed return on common equity are to be returned to customers through a credit, pursuant to the terms of the global stipulated settlement agreement. The 2024 test year evaluation produced an earned return on common equity of 9.98%, which is within the approved formula rate plan bandwidth, but above the allowed return on common equity, resulting in a customer credit of $31.9 million to be returned to customers during September and October 2025.

Other changes in formula rate plan revenue are driven by higher nuclear depreciation rates, additions to transmission and distribution plant in service reflected through the transmission recovery mechanism and distribution recovery mechanism, and the expiration of customer credits related to the LPSC’s order, offset by increased customer credits resulting from an increase in net MISO revenues reflected through the MISO cost recovery mechanism and the reduction in the Louisiana corporate income tax rate effective January 1, 2025, reflected through the tax adjustment mechanism, as discussed below. Excluding the customer credit for earnings above the authorized return on common equity discussed above, the net result of these changes on an annualized basis is a $2 million increase in formula rate plan revenue.

As noted above, the 2024 evaluation report included the effects of the change in Louisiana state tax law that reduced the corporate income tax rate to a flat 5.5% (from the then-current highest marginal rate of 7.5%) effective January 1, 2025. As such, the 2024 evaluation report reflected the calculation of current and deferred income tax expenses as well as the revaluation of accumulated deferred income taxes based on the income tax laws currently in effect. The 2024 evaluation report proposes that the rate effects associated with the revaluation of accumulated deferred income taxes, including the collection of any net accumulated deferred income tax deficiency and any related effects on rate base, should be reflected in the tax adjustment mechanism consistent with the treatment of similar Tax Cuts and Jobs Act and prior state tax change-related impacts. The effects of the change in tax law on Entergy Louisiana’s authorized return on rate base are also reflected in the 2024 evaluation report consistent with the treatment cited above, including a credit in the extraordinary cost change mechanism for the prospective change in Entergy Louisiana’s authorized return and a credit within the tax adjustment mechanism for over-collection of income tax expense through August 2025.

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 February 2025, Entergy Louisiana filed supplemental testimony with the LPSC stating that the third combined cycle combustion turbine resource presented in the October 2024 application would be sited at Entergy Louisiana’s Waterford site in Killona, Louisiana, alongside existing Entergy Louisiana generation resources. The testimony also notes that Entergy Louisiana is negotiating with the customer in response to the customer’s request to increase the load associated with its project in north Louisiana. The testimony indicates further that the additional load can be served without additional generation capacity beyond what was presented in the October 2024 application, but that additional transmission facilities, which will be funded directly by the customer, are needed to serve this additional load.

In April 2025 and May 2025 the LPSC staff and certain intervenors each filed their direct testimony and cross-answering testimony, respectively. The LPSC staff’s testimony discussed the significant projected benefits associated with the data center project; however, both the LPSC staff and such intervenors also identified purported risks associated with constructing the requested resources based on the terms and conditions under which the customer would be taking service. Both the LPSC staff and such intervenors also recommended that the LPSC impose certain conditions on its approval which, if adopted, would support approval of Entergy Louisiana’s application. The LPSC staff’s recommendations included 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 recommended 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 advocated 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 May 2025, Entergy Louisiana filed its rebuttal testimony responding to the direct and cross-answering testimony of the LPSC staff and intervenors. The rebuttal testimony expressed support for or no opposition to the LPSC’s adoption of certain of the proposed recommendations and identified why other proposed recommendations should not be adopted. In addition, the rebuttal testimony stated that the negotiations related to the increase in the load amount for the customer’s project had concluded and that a rider to the electric service agreement reflecting this increase had been executed. In advance of the July 2025 hearing, Entergy Louisiana reached a settlement agreement with the LPSC staff and three separate intervenors. The hearing concluded and the matter is currently under consideration by the ALJ.

COVID-19 Orders

As discussed in the Form 10-K, in April 2020 the LPSC issued an order authorizing utilities to record as a regulatory asset expenses incurred from the suspension of disconnections and collection of late fees imposed by LPSC orders associated with the COVID-19 pandemic. In April 2023, Entergy Louisiana filed an application proposing to utilize approximately $1.6 billion in certain low interest debt to generate earnings to apply toward the reduction of the COVID-19 regulatory asset, as well as to conduct additional outside right-of-way vegetation management activities and fund the minor storm reserve account. In that filing, Entergy Louisiana proposed to delay repayment of certain shorter-term first mortgage bonds that were issued to finance storm restoration costs until the costs could be securitized, and to invest the funds that otherwise would be used to repay those bonds in the money pool to take advantage of the spread between prevailing interest rates on investments in the money pool and the interest rates on the bonds. The LPSC approved Entergy Louisiana’s requested relief in June 2023. In November 2024, Entergy Louisiana submitted a filing to the LPSC requesting that the LPSC review Entergy Louisiana’s computation of the COVID-19 regulatory asset as well as Entergy Louisiana’s proposal to offset the regulatory asset against the net interest earned on the short-term debt funds, resulting in no increased costs to customers. At the time of the filing, Entergy Louisiana had a regulatory asset of $47.8 million for costs associated

with the COVID-19 pandemic. As of June 30, 2025, Entergy Louisiana had a regulatory liability of $48.9 million for the deferred earnings related to the approximately $1.6 billion in low interest debt, which had been fully repaid by August 2024. In granting Entergy Louisiana’s requested relief in June 2023, the LPSC ordered that any amount of earnings exceeding the amount of the COVID-19 regulatory asset be transferred to Entergy Louisiana’s storm reserve escrow account. In May 2025 the LPSC staff filed direct testimony finding that Entergy Louisiana had complied with the relevant orders and recommending approval of the requested treatment. In June 2025, Entergy Louisiana and the LPSC staff filed a joint motion requesting a hearing for the admission of an uncontested stipulated settlement agreement in the matter. A settlement hearing took place in July 2025 and Entergy Louisiana expects the settlement to be considered at an upcoming meeting of the LPSC. The settlement terms provide for LPSC approval of Entergy Louisiana’s calculation of the COVID-19 regulatory assets and Entergy Louisiana’s proposal to offset the regulatory asset as described above and as proposed in Entergy Louisiana’s November 2024 filing.

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 also to be within the formula rate plan bandwidth. The 2025 test year filing showed 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 proposed 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.

In June 2025, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2025 test year filing, with the exception of immaterial adjustments to certain operation and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2025, resulting in no change in formula rate plan revenues for 2025. Pursuant to the stipulation, Entergy Mississippi’s 2024 look-back filing reflected an earned return on rate base of 7.55%, which also resulted in no change in formula rate plan revenues for 2024. In addition, the stipulation included the recovery of the two outside-the-bandwidth changes discussed above as well as the ratemaking treatment of customer contributions (deferred revenue and prepaid contributions in aid of construction). In June 2025 the MPSC approved the joint stipulation with rates effective in July 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% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million. 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. The City Council’s advisors issued their report in July 2025 seeking a reduction in Entergy New Orleans’s requested electric formula rate plan revenues of approximately $7.2 million due to certain proposed cost realignments and disallowances, of which $4.1 million is associated with Entergy New Orleans’s proposed implementation, on a revenue neutral basis, of a proposed reduction in customer late fees. The City Council’s advisors also proposed rate mitigation in the amount of $4.4 million through offsets to the formula rate plan funded by certain regulatory liabilities. The City Council’s advisors’ report began a 35-day period to resolve any disputes among the parties regarding the formula rate plan. For any disputed rate adjustments, 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 amended rider was 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 then-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. In June 2025 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective on June 25, 2025.

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. In June 2025 the United States Supreme Court denied Entergy Arkansas’s petition for certiorari.

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. In May 2025, Entergy Services filed a response to the formal challenge and is awaiting a response from the FERC.

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 are updates 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. In April 2025 the FERC accepted System Energy’s tariff compliance filing.

System Energy Settlement with the LPSC

As discussed in the Form 10-K, in 2024, System Energy reached a settlement with the LPSC to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC (including all docketed proceedings resolved by the MPSC, the APSC, and the City Council settlements) and associated with System Energy’s past implementation of the Unit Power Sales Agreement. In compliance with the settlement, in May 2025, System Energy, Entergy Louisiana, and Entergy Mississippi submitted the following filings with the FERC: (1) a Federal Power Act Section 203 application seeking approval for the permanent divestiture by Entergy Louisiana to Entergy Mississippi of its rights to capacity and energy from Grand Gulf; and (2) a Federal Power Act Section 205 application seeking approval to modify the entitlement percentages of the remaining purchasers under the Unit Power Sales Agreement in connection with the foregoing divestiture. In July 2025, the FERC issued an order accepting the Federal Power Act Section 205 application to remove Entergy Louisiana as a party to the Unit Power Sales Agreement. As a result of the order, the Unit Power Sales Agreement entitlement percentages of the remaining purchasers will be permanently modified to exclude Entergy Louisiana, to be effective beginning October 2025. The FERC also issued an order dismissing the Federal Power Act Section 203 application based on lack of jurisdiction.

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 June 2025 the LPSC staff filed direct testimony. The LPSC staff recommends approval of Entergy Louisiana’s as-requested storm restoration costs with the exception of approximately $10.6 million, comprised primarily of estimates of mutual assistance invoices that have not yet been received at the time of filing and that ultimately exceeded the actual amounts invoiced, as well as certain incentive compensation, and $1.8 million associated with certain carrying costs. Entergy Louisiana’s rebuttal testimony is due in August 2025 and a hearing is scheduled for November 2025.

Regulatory Assets and Regulatory Liabilities

See Note 2 to the financial statements in the Form 10-K for information regarding regulatory assets and regulatory liabilities in the Utility business presented on the balance sheets of Entergy and the Registrant Subsidiaries.  The following are updates to that discussion.

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 LPSC accepted the report in June 2025.

Entergy Texas

As discussed in the Form 10-K, in September 2024, Entergy Texas filed an application with the PUCT to reconcile its fuel and purchased power costs for the period from April 2022 through March 2024. During the reconciliation period, Entergy Texas incurred approximately $1.6 billion in eligible fuel and purchased power expenses to generate and purchase electricity to serve its customers, net of certain revenues credited to such expenses and other adjustments. Entergy Texas’s cumulative under-recovery balance for the reconciliation period was approximately $30 million, including interest, which Entergy Texas requested authority to carry over as part of the cumulative fuel balance for the subsequent reconciliation period beginning April 2024. In November 2024 the PUCT referred the proceeding to the State Office of Administrative Hearings. In March 2025, Texas Industrial Energy Consumers, an intervenor, filed testimony regarding the recovery of capacity costs for a certain power purchase agreement, arguing the capacity costs should be imputed and treated as non-reconcilable fuel expense, recovered in Entergy Texas’s base rates. In April 2025 the PUCT staff filed testimony and later in April 2025, Entergy Texas filed rebuttal testimony. In May 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a request for a paper hearing and to cancel the oral hearing on the merits previously scheduled for later in May 2025. In June 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a joint motion to abate the proceeding to give the parties to the proceeding additional time to finalize a settlement.

Filings with the APSC (Entergy Arkansas)

Retail Rates

2025 Formula Rate Plan Filing

In July 2025, Entergy Arkansas filed with the APSC its 2025 formula rate plan filing to set its formula rate for the 2026 calendar year.  The filing contained an evaluation of Entergy Arkansas’s earnings for the 2026 projected year and a netting adjustment for the 2024 historical year.  The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2026 projected year was 8.45% resulting in a revenue deficiency of $68.9 million.  The earned rate of return on common equity for the 2024 historical year was 7.71% resulting in a $48.8 million netting adjustment.  The total proposed revenue change for the 2026 projected year and 2024 historical year netting adjustment is $117.7 million.   By operation of the formula rate plan, Entergy Arkansas’s recovery of the revenue requirement is subject to a four percent annual revenue constraint.  Because Entergy Arkansas’s revenue requirement in this filing exceeded the constraint, the resulting increase was limited to $92.3 million. Entergy Arkansas proposed a procedural schedule that includes a hearing in November 2025 and requests an APSC order in December 2025.

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 had been issued. Credits to retail customers were completed in second quarter 2025, and the Grand Gulf credit rider was subsequently withdrawn.

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 approved by the LPSC also in August 2024, 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 were 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.

2024 Formula Rate Plan Filing

In May 2025, Entergy Louisiana filed its formula rate plan evaluation report for its 2024 calendar year operations. Consistent with the global stipulated settlement agreement approved by the LPSC in August 2024, 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 test year 2024, however, any earnings above the allowed return on common equity are to be returned to customers through a credit, pursuant to the terms of the global stipulated settlement agreement. The 2024 test year evaluation produced an earned return on common equity of 9.98%, which is within the approved formula rate plan bandwidth, but above the allowed return on common equity, resulting in a customer credit of $31.9 million to be returned to customers during September and October 2025.

Other changes in formula rate plan revenue are driven by higher nuclear depreciation rates, additions to transmission and distribution plant in service reflected through the transmission recovery mechanism and distribution recovery mechanism, and the expiration of customer credits related to the LPSC’s order, offset by increased customer credits resulting from an increase in net MISO revenues reflected through the MISO cost recovery mechanism and the reduction in the Louisiana corporate income tax rate effective January 1, 2025, reflected through the tax adjustment mechanism, as discussed below. Excluding the customer credit for earnings above the authorized return on common equity discussed above, the net result of these changes on an annualized basis is a $2 million increase in formula rate plan revenue.

As noted above, the 2024 evaluation report included the effects of the change in Louisiana state tax law that reduced the corporate income tax rate to a flat 5.5% (from the then-current highest marginal rate of 7.5%) effective January 1, 2025. As such, the 2024 evaluation report reflected the calculation of current and deferred income tax expenses as well as the revaluation of accumulated deferred income taxes based on the income tax laws currently in effect. The 2024 evaluation report proposes that the rate effects associated with the revaluation of accumulated deferred income taxes, including the collection of any net accumulated deferred income tax deficiency and any related effects on rate base, should be reflected in the tax adjustment mechanism consistent with the treatment of similar Tax Cuts and Jobs Act and prior state tax change-related impacts. The effects of the change in tax law on Entergy Louisiana’s authorized return on rate base are also reflected in the 2024 evaluation report consistent with the treatment cited above, including a credit in the extraordinary cost change mechanism for the prospective change in Entergy Louisiana’s authorized return and a credit within the tax adjustment mechanism for over-collection of income tax expense through August 2025.

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 February 2025, Entergy Louisiana filed supplemental testimony with the LPSC stating that the third combined cycle combustion turbine resource presented in the October 2024 application would be sited at Entergy Louisiana’s Waterford site in Killona, Louisiana, alongside existing Entergy Louisiana generation resources. The testimony also notes that Entergy Louisiana is negotiating with the customer in response to the customer’s request to increase the load associated with its project in north Louisiana. The testimony indicates further that the additional load can be served without additional generation capacity beyond what was presented in the October 2024 application, but that additional transmission facilities, which will be funded directly by the customer, are needed to serve this additional load.

In April 2025 and May 2025 the LPSC staff and certain intervenors each filed their direct testimony and cross-answering testimony, respectively. The LPSC staff’s testimony discussed the significant projected benefits associated with the data center project; however, both the LPSC staff and such intervenors also identified purported risks associated with constructing the requested resources based on the terms and conditions under which the customer would be taking service. Both the LPSC staff and such intervenors also recommended that the LPSC impose certain conditions on its approval which, if adopted, would support approval of Entergy Louisiana’s application. The LPSC staff’s recommendations included 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 recommended 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 advocated 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 May 2025, Entergy Louisiana filed its rebuttal testimony responding to the direct and cross-answering testimony of the LPSC staff and intervenors. The rebuttal testimony expressed support for or no opposition to the LPSC’s adoption of certain of the proposed recommendations and identified why other proposed recommendations should not be adopted. In addition, the rebuttal testimony stated that the negotiations related to the increase in the load amount for the customer’s project had concluded and that a rider to the electric service agreement reflecting this increase had been executed. In advance of the July 2025 hearing, Entergy Louisiana reached a settlement agreement with the LPSC staff and three separate intervenors. The hearing concluded and the matter is currently under consideration by the ALJ.

COVID-19 Orders

As discussed in the Form 10-K, in April 2020 the LPSC issued an order authorizing utilities to record as a regulatory asset expenses incurred from the suspension of disconnections and collection of late fees imposed by LPSC orders associated with the COVID-19 pandemic. In April 2023, Entergy Louisiana filed an application proposing to utilize approximately $1.6 billion in certain low interest debt to generate earnings to apply toward the reduction of the COVID-19 regulatory asset, as well as to conduct additional outside right-of-way vegetation management activities and fund the minor storm reserve account. In that filing, Entergy Louisiana proposed to delay repayment of certain shorter-term first mortgage bonds that were issued to finance storm restoration costs until the costs could be securitized, and to invest the funds that otherwise would be used to repay those bonds in the money pool to take advantage of the spread between prevailing interest rates on investments in the money pool and the interest rates on the bonds. The LPSC approved Entergy Louisiana’s requested relief in June 2023. In November 2024, Entergy Louisiana submitted a filing to the LPSC requesting that the LPSC review Entergy Louisiana’s computation of the COVID-19 regulatory asset as well as Entergy Louisiana’s proposal to offset the regulatory asset against the net interest earned on the short-term debt funds, resulting in no increased costs to customers. At the time of the filing, Entergy Louisiana had a regulatory asset of $47.8 million for costs associated

with the COVID-19 pandemic. As of June 30, 2025, Entergy Louisiana had a regulatory liability of $48.9 million for the deferred earnings related to the approximately $1.6 billion in low interest debt, which had been fully repaid by August 2024. In granting Entergy Louisiana’s requested relief in June 2023, the LPSC ordered that any amount of earnings exceeding the amount of the COVID-19 regulatory asset be transferred to Entergy Louisiana’s storm reserve escrow account. In May 2025 the LPSC staff filed direct testimony finding that Entergy Louisiana had complied with the relevant orders and recommending approval of the requested treatment. In June 2025, Entergy Louisiana and the LPSC staff filed a joint motion requesting a hearing for the admission of an uncontested stipulated settlement agreement in the matter. A settlement hearing took place in July 2025 and Entergy Louisiana expects the settlement to be considered at an upcoming meeting of the LPSC. The settlement terms provide for LPSC approval of Entergy Louisiana’s calculation of the COVID-19 regulatory assets and Entergy Louisiana’s proposal to offset the regulatory asset as described above and as proposed in Entergy Louisiana’s November 2024 filing.

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 also to be within the formula rate plan bandwidth. The 2025 test year filing showed 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 proposed 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.

In June 2025, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2025 test year filing, with the exception of immaterial adjustments to certain operation and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2025, resulting in no change in formula rate plan revenues for 2025. Pursuant to the stipulation, Entergy Mississippi’s 2024 look-back filing reflected an earned return on rate base of 7.55%, which also resulted in no change in formula rate plan revenues for 2024. In addition, the stipulation included the recovery of the two outside-the-bandwidth changes discussed above as well as the ratemaking treatment of customer contributions (deferred revenue and prepaid contributions in aid of construction). In June 2025 the MPSC approved the joint stipulation with rates effective in July 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% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million. 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. The City Council’s advisors issued their report in July 2025 seeking a reduction in Entergy New Orleans’s requested electric formula rate plan revenues of approximately $7.2 million due to certain proposed cost realignments and disallowances, of which $4.1 million is associated with Entergy New Orleans’s proposed implementation, on a revenue neutral basis, of a proposed reduction in customer late fees. The City Council’s advisors also proposed rate mitigation in the amount of $4.4 million through offsets to the formula rate plan funded by certain regulatory liabilities. The City Council’s advisors’ report began a 35-day period to resolve any disputes among the parties regarding the formula rate plan. For any disputed rate adjustments, 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 amended rider was 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 then-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. In June 2025 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective on June 25, 2025.

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. In June 2025 the United States Supreme Court denied Entergy Arkansas’s petition for certiorari.

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. In May 2025, Entergy Services filed a response to the formal challenge and is awaiting a response from the FERC.

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 are updates 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. In April 2025 the FERC accepted System Energy’s tariff compliance filing.

System Energy Settlement with the LPSC

As discussed in the Form 10-K, in 2024, System Energy reached a settlement with the LPSC to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC (including all docketed proceedings resolved by the MPSC, the APSC, and the City Council settlements) and associated with System Energy’s past implementation of the Unit Power Sales Agreement. In compliance with the settlement, in May 2025, System Energy, Entergy Louisiana, and Entergy Mississippi submitted the following filings with the FERC: (1) a Federal Power Act Section 203 application seeking approval for the permanent divestiture by Entergy Louisiana to Entergy Mississippi of its rights to capacity and energy from Grand Gulf; and (2) a Federal Power Act Section 205 application seeking approval to modify the entitlement percentages of the remaining purchasers under the Unit Power Sales Agreement in connection with the foregoing divestiture. In July 2025, the FERC issued an order accepting the Federal Power Act Section 205 application to remove Entergy Louisiana as a party to the Unit Power Sales Agreement. As a result of the order, the Unit Power Sales Agreement entitlement percentages of the remaining purchasers will be permanently modified to exclude Entergy Louisiana, to be effective beginning October 2025. The FERC also issued an order dismissing the Federal Power Act Section 203 application based on lack of jurisdiction.

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 June 2025 the LPSC staff filed direct testimony. The LPSC staff recommends approval of Entergy Louisiana’s as-requested storm restoration costs with the exception of approximately $10.6 million, comprised primarily of estimates of mutual assistance invoices that have not yet been received at the time of filing and that ultimately exceeded the actual amounts invoiced, as well as certain incentive compensation, and $1.8 million associated with certain carrying costs. Entergy Louisiana’s rebuttal testimony is due in August 2025 and a hearing is scheduled for November 2025.

Regulatory Assets and Regulatory Liabilities

See Note 2 to the financial statements in the Form 10-K for information regarding regulatory assets and regulatory liabilities in the Utility business presented on the balance sheets of Entergy and the Registrant Subsidiaries.  The following are updates to that discussion.

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 LPSC accepted the report in June 2025.

Entergy Texas

As discussed in the Form 10-K, in September 2024, Entergy Texas filed an application with the PUCT to reconcile its fuel and purchased power costs for the period from April 2022 through March 2024. During the reconciliation period, Entergy Texas incurred approximately $1.6 billion in eligible fuel and purchased power expenses to generate and purchase electricity to serve its customers, net of certain revenues credited to such expenses and other adjustments. Entergy Texas’s cumulative under-recovery balance for the reconciliation period was approximately $30 million, including interest, which Entergy Texas requested authority to carry over as part of the cumulative fuel balance for the subsequent reconciliation period beginning April 2024. In November 2024 the PUCT referred the proceeding to the State Office of Administrative Hearings. In March 2025, Texas Industrial Energy Consumers, an intervenor, filed testimony regarding the recovery of capacity costs for a certain power purchase agreement, arguing the capacity costs should be imputed and treated as non-reconcilable fuel expense, recovered in Entergy Texas’s base rates. In April 2025 the PUCT staff filed testimony and later in April 2025, Entergy Texas filed rebuttal testimony. In May 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a request for a paper hearing and to cancel the oral hearing on the merits previously scheduled for later in May 2025. In June 2025, Entergy Texas filed, and the ALJ with the State Office of Administrative Hearings granted, a joint motion to abate the proceeding to give the parties to the proceeding additional time to finalize a settlement.

In July 2025, Entergy Arkansas filed with the APSC its 2025 formula rate plan filing to set its formula rate for the 2026 calendar year.  The filing contained an evaluation of Entergy Arkansas’s earnings for the 2026 projected year and a netting adjustment for the 2024 historical year.  The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2026 projected year was 8.45% resulting in a revenue deficiency of $68.9 million.  The earned rate of return on common equity for the 2024 historical year was 7.71% resulting in a $48.8 million netting adjustment.  The total proposed revenue change for the 2026 projected year and 2024 historical year netting adjustment is $117.7 million.   By operation of the formula rate plan, Entergy Arkansas’s recovery of the revenue requirement is subject to a four percent annual revenue constraint.  Because Entergy Arkansas’s revenue requirement in this filing exceeded the constraint, the resulting increase was limited to $92.3 million. Entergy Arkansas proposed a procedural schedule that includes a hearing in November 2025 and requests an APSC order in December 2025.

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 had been issued. Credits to retail customers were completed in second quarter 2025, and the Grand Gulf credit rider was subsequently withdrawn.

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 approved by the LPSC also in August 2024, 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 were 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.

2024 Formula Rate Plan Filing

In May 2025, Entergy Louisiana filed its formula rate plan evaluation report for its 2024 calendar year operations. Consistent with the global stipulated settlement agreement approved by the LPSC in August 2024, 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 test year 2024, however, any earnings above the allowed return on common equity are to be returned to customers through a credit, pursuant to the terms of the global stipulated settlement agreement. The 2024 test year evaluation produced an earned return on common equity of 9.98%, which is within the approved formula rate plan bandwidth, but above the allowed return on common equity, resulting in a customer credit of $31.9 million to be returned to customers during September and October 2025.

Other changes in formula rate plan revenue are driven by higher nuclear depreciation rates, additions to transmission and distribution plant in service reflected through the transmission recovery mechanism and distribution recovery mechanism, and the expiration of customer credits related to the LPSC’s order, offset by increased customer credits resulting from an increase in net MISO revenues reflected through the MISO cost recovery mechanism and the reduction in the Louisiana corporate income tax rate effective January 1, 2025, reflected through the tax adjustment mechanism, as discussed below. Excluding the customer credit for earnings above the authorized return on common equity discussed above, the net result of these changes on an annualized basis is a $2 million increase in formula rate plan revenue.

As noted above, the 2024 evaluation report included the effects of the change in Louisiana state tax law that reduced the corporate income tax rate to a flat 5.5% (from the then-current highest marginal rate of 7.5%) effective January 1, 2025. As such, the 2024 evaluation report reflected the calculation of current and deferred income tax expenses as well as the revaluation of accumulated deferred income taxes based on the income tax laws currently in effect. The 2024 evaluation report proposes that the rate effects associated with the revaluation of accumulated deferred income taxes, including the collection of any net accumulated deferred income tax deficiency and any related effects on rate base, should be reflected in the tax adjustment mechanism consistent with the treatment of similar Tax Cuts and Jobs Act and prior state tax change-related impacts. The effects of the change in tax law on Entergy Louisiana’s authorized return on rate base are also reflected in the 2024 evaluation report consistent with the treatment cited above, including a credit in the extraordinary cost change mechanism for the prospective change in Entergy Louisiana’s authorized return and a credit within the tax adjustment mechanism for over-collection of income tax expense through August 2025.

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 February 2025, Entergy Louisiana filed supplemental testimony with the LPSC stating that the third combined cycle combustion turbine resource presented in the October 2024 application would be sited at Entergy Louisiana’s Waterford site in Killona, Louisiana, alongside existing Entergy Louisiana generation resources. The testimony also notes that Entergy Louisiana is negotiating with the customer in response to the customer’s request to increase the load associated with its project in north Louisiana. The testimony indicates further that the additional load can be served without additional generation capacity beyond what was presented in the October 2024 application, but that additional transmission facilities, which will be funded directly by the customer, are needed to serve this additional load.

In April 2025 and May 2025 the LPSC staff and certain intervenors each filed their direct testimony and cross-answering testimony, respectively. The LPSC staff’s testimony discussed the significant projected benefits associated with the data center project; however, both the LPSC staff and such intervenors also identified purported risks associated with constructing the requested resources based on the terms and conditions under which the customer would be taking service. Both the LPSC staff and such intervenors also recommended that the LPSC impose certain conditions on its approval which, if adopted, would support approval of Entergy Louisiana’s application. The LPSC staff’s recommendations included 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 recommended 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 advocated 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 May 2025, Entergy Louisiana filed its rebuttal testimony responding to the direct and cross-answering testimony of the LPSC staff and intervenors. The rebuttal testimony expressed support for or no opposition to the LPSC’s adoption of certain of the proposed recommendations and identified why other proposed recommendations should not be adopted. In addition, the rebuttal testimony stated that the negotiations related to the increase in the load amount for the customer’s project had concluded and that a rider to the electric service agreement reflecting this increase had been executed. In advance of the July 2025 hearing, Entergy Louisiana reached a settlement agreement with the LPSC staff and three separate intervenors. The hearing concluded and the matter is currently under consideration by the ALJ.

COVID-19 Orders

As discussed in the Form 10-K, in April 2020 the LPSC issued an order authorizing utilities to record as a regulatory asset expenses incurred from the suspension of disconnections and collection of late fees imposed by LPSC orders associated with the COVID-19 pandemic. In April 2023, Entergy Louisiana filed an application proposing to utilize approximately $1.6 billion in certain low interest debt to generate earnings to apply toward the reduction of the COVID-19 regulatory asset, as well as to conduct additional outside right-of-way vegetation management activities and fund the minor storm reserve account. In that filing, Entergy Louisiana proposed to delay repayment of certain shorter-term first mortgage bonds that were issued to finance storm restoration costs until the costs could be securitized, and to invest the funds that otherwise would be used to repay those bonds in the money pool to take advantage of the spread between prevailing interest rates on investments in the money pool and the interest rates on the bonds. The LPSC approved Entergy Louisiana’s requested relief in June 2023. In November 2024, Entergy Louisiana submitted a filing to the LPSC requesting that the LPSC review Entergy Louisiana’s computation of the COVID-19 regulatory asset as well as Entergy Louisiana’s proposal to offset the regulatory asset against the net interest earned on the short-term debt funds, resulting in no increased costs to customers. At the time of the filing, Entergy Louisiana had a regulatory asset of $47.8 million for costs associated

with the COVID-19 pandemic. As of June 30, 2025, Entergy Louisiana had a regulatory liability of $48.9 million for the deferred earnings related to the approximately $1.6 billion in low interest debt, which had been fully repaid by August 2024. In granting Entergy Louisiana’s requested relief in June 2023, the LPSC ordered that any amount of earnings exceeding the amount of the COVID-19 regulatory asset be transferred to Entergy Louisiana’s storm reserve escrow account. In May 2025 the LPSC staff filed direct testimony finding that Entergy Louisiana had complied with the relevant orders and recommending approval of the requested treatment. In June 2025, Entergy Louisiana and the LPSC staff filed a joint motion requesting a hearing for the admission of an uncontested stipulated settlement agreement in the matter. A settlement hearing took place in July 2025 and Entergy Louisiana expects the settlement to be considered at an upcoming meeting of the LPSC. The settlement terms provide for LPSC approval of Entergy Louisiana’s calculation of the COVID-19 regulatory assets and Entergy Louisiana’s proposal to offset the regulatory asset as described above and as proposed in Entergy Louisiana’s November 2024 filing.

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 also to be within the formula rate plan bandwidth. The 2025 test year filing showed 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 proposed 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.

In June 2025, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2025 test year filing, with the exception of immaterial adjustments to certain operation and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2025, resulting in no change in formula rate plan revenues for 2025. Pursuant to the stipulation, Entergy Mississippi’s 2024 look-back filing reflected an earned return on rate base of 7.55%, which also resulted in no change in formula rate plan revenues for 2024. In addition, the stipulation included the recovery of the two outside-the-bandwidth changes discussed above as well as the ratemaking treatment of customer contributions (deferred revenue and prepaid contributions in aid of construction). In June 2025 the MPSC approved the joint stipulation with rates effective in July 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% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in a decrease in electric rates of $13.8 million. 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. The City Council’s advisors issued their report in July 2025 seeking a reduction in Entergy New Orleans’s requested electric formula rate plan revenues of approximately $7.2 million due to certain proposed cost realignments and disallowances, of which $4.1 million is associated with Entergy New Orleans’s proposed implementation, on a revenue neutral basis, of a proposed reduction in customer late fees. The City Council’s advisors also proposed rate mitigation in the amount of $4.4 million through offsets to the formula rate plan funded by certain regulatory liabilities. The City Council’s advisors’ report began a 35-day period to resolve any disputes among the parties regarding the formula rate plan. For any disputed rate adjustments, 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 amended rider was 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 then-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. In June 2025 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective on June 25, 2025.

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. In June 2025 the United States Supreme Court denied Entergy Arkansas’s petition for certiorari.

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. In May 2025, Entergy Services filed a response to the formal challenge and is awaiting a response from the FERC.

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 are updates 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. In April 2025 the FERC accepted System Energy’s tariff compliance filing.

System Energy Settlement with the LPSC

As discussed in the Form 10-K, in 2024, System Energy reached a settlement with the LPSC to globally resolve all of the LPSC’s actual and potential claims in multiple docketed proceedings pending before the FERC (including all docketed proceedings resolved by the MPSC, the APSC, and the City Council settlements) and associated with System Energy’s past implementation of the Unit Power Sales Agreement. In compliance with the settlement, in May 2025, System Energy, Entergy Louisiana, and Entergy Mississippi submitted the following filings with the FERC: (1) a Federal Power Act Section 203 application seeking approval for the permanent divestiture by Entergy Louisiana to Entergy Mississippi of its rights to capacity and energy from Grand Gulf; and (2) a Federal Power Act Section 205 application seeking approval to modify the entitlement percentages of the remaining purchasers under the Unit Power Sales Agreement in connection with the foregoing divestiture. In July 2025, the FERC issued an order accepting the Federal Power Act Section 205 application to remove Entergy Louisiana as a party to the Unit Power Sales Agreement. As a result of the order, the Unit Power Sales Agreement entitlement percentages of the remaining purchasers will be permanently modified to exclude Entergy Louisiana, to be effective beginning October 2025. The FERC also issued an order dismissing the Federal Power Act Section 203 application based on lack of jurisdiction.

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 June 2025 the LPSC staff filed direct testimony. The LPSC staff recommends approval of Entergy Louisiana’s as-requested storm restoration costs with the exception of approximately $10.6 million, comprised primarily of estimates of mutual assistance invoices that have not yet been received at the time of filing and that ultimately exceeded the actual amounts invoiced, as well as certain incentive compensation, and $1.8 million associated with certain carrying costs. Entergy Louisiana’s rebuttal testimony is due in August 2025 and a hearing is scheduled for November 2025.
