Public Utilities Disclosure [Text Block]	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 2026, 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 $0.01333 per kWh to $0.01508 per kWh. The primary reason for the rate increase was an under-recovered balance as a result of higher natural gas prices in 2025. Based on circumstances related to ANO 2’s refueling outage, Entergy Arkansas made an adjustment to projected energy costs to phase-in the rate increase gradually. The redetermined rate of $0.01508 per kWh became effective with the first billing cycle in April 2026 through the normal operation of the tariff. Entergy Louisiana As discussed in the Form 10-K, in June 2025 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings (for Entergy Louisiana’s gas operations). The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from January 2023 through June 2025. The LPSC staff issued its audit report in March 2026. The next step is for the LPSC to issue its final report, but there is no deadline or timing requirement associated with the issuance of the final report. In February 2026, Entergy Louisiana, in its monthly filing to update its fuel adjustment clause, requested to defer approximately $141.9 million of fuel costs incurred in January 2026 that were primarily attributable to the effects of Winter Storm Fern, consistent with the LPSC’s general order approved at its February 2026 meeting permitting temporary modifications to the LPSC’s fuel adjustment clause general order. The filing proposed to defer the recovery of these fuel costs over a four-month period from March 2026 through June 2026 to mitigate the customer bill impacts of these fuel costs. In March 2026 the LPSC issued a special order delegating authority to the LPSC executive secretary to review and approve utility-specific requests for deferral of fuel costs from Winter Storm Fern, subject to audit as per the LPSC’s fuel clause general order. In April 2026 the LPSC executive secretary approved Entergy Louisiana’s request for deferral. In April 2026 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2023 through 2025. Discovery is ongoing, and no audit report has been filed. 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 2026 Base Rate Case In February 2026, Entergy Arkansas filed with the APSC a general change in rates, charges, and tariffs. The filing requested a base rate increase to recover a base rate revenue deficiency of $44.6 million and notified the APSC of Entergy Arkansas’s intent to implement a forward test year formula rate plan pursuant to Arkansas legislation passed in 2015. The primary drivers of the revenue deficiency were increased depreciation expense and the impact of net capital additions. Additionally, the filing requested a 9.90% return on common equity and increased depreciation rates as the result of a depreciation study. In March 2026 the APSC issued an order suspending the proposed rates and tariffs filed by Entergy Arkansas. In June 2026 the APSC established a procedural schedule with an evidentiary hearing scheduled to begin in November 2026, and in July 2026 a number of intervenors moved to modify the schedule to conduct additional discovery. Entergy Arkansas opposed the motion in part based on the voluminous discovery conducted to date. 2026 Formula Rate Plan Filing In July 2026, Entergy Arkansas filed with the APSC its 2026 formula rate plan filing to set its formula rate for the 2027 calendar year. The filing contained an evaluation of Entergy Arkansas’s earnings and a netting adjustment for the 2025 historical year. The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2025 historical year was 8.8%, resulting in a $47.2 million formula rate plan revenue increase to produce a 9.65% earned rate of return on common equity. When combined with 2025 historical year formula rate plan revenues of $56.0 million, the total proposed revenue change for the 2025 historical year netting adjustment is a reduction of $8.8 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. Entergy Arkansas’s revenue requirement in this filing did not exceed the constraint. In second quarter 2026, Entergy Arkansas recorded a regulatory liability of $8.8 million to reflect the amount of the 2025 historical year netting adjustment that it collected from customers during the 2025 rate effective period. Generating Arkansas Jobs Act Rider In March 2026, Entergy Arkansas filed its first annual update to the strategic investment recovery rider, requesting recovery of $110.4 million of financing costs during construction of generation and transmission strategic investments related to Ironwood Power Station, Jefferson Power Station, and the Arkansas Cypress Solar facility. The revised rates were requested to be effective with the first billing cycle of June 2026. In April 2026 the APSC general staff filed testimony arguing that the APSC had not issued an order designating Ironwood Power Station as a strategic investment and that related costs should therefore be removed from the annual update. Also in April 2026, Entergy Arkansas filed testimony asserting that the APSC general staff’s position is contrary to the plain language of the statute, which includes an exception for facilities like Ironwood Power Station that were certified by the APSC within a certain timeframe. A hearing was held in April 2026. In June 2026 the APSC approved Entergy Arkansas’s annual update, and rates became effective June 4, 2026. Production Tax Credit Tariffs As discussed in Note 3 to the financial statements in the Form 10-K, in January 2026 the APSC opened a docket to investigate the sale of Entergy Arkansas’s nuclear production tax credits and the appropriate ratemaking treatment of production tax credits for all of Entergy Arkansas’s eligible resources, including how the proceeds of any sales should flow through to customers. For nuclear production tax credits, Entergy Arkansas proposed a nuclear production tax credit rider, which would provide for the immediate flow through to customers of the weighted average cost of capital return on the net proceeds of the monetized nuclear production tax credits. Recognizing that the timing and determination from the IRS is uncertain, the nuclear production tax credit rider also proposes that, if there is an unfavorable IRS determination, Entergy Arkansas would collect applicable costs from customers. As directed by the APSC, in February 2026, Entergy Arkansas submitted a compliance filing to the APSC verifying the status of the solar production tax credits. The filing also verified that the net proceeds from the sale of the nuclear production tax credits were recorded in FERC accounts that are accruing a return for customers’ benefit at a rate that is above the customer deposit rate. Subsequently, in March 2026, Entergy Arkansas filed testimony setting forth its proposal for the solar production tax credits. Specifically, Entergy Arkansas requested the same ratemaking treatment for all of the solar facilities that the APSC already approved for Walnut Bend (i.e., the total net monetized proceeds from production tax credits expected to be generated over the first ten years of a solar facility’s operation are estimated and then amortized over the expected useful life of the asset, which is typically 30 years). Additionally, consistent with prior orders for these resources, the regulatory liabilities associated with the net cash proceeds from monetized solar production tax credits will be included in Entergy Arkansas’s calculation of its weighted average cost of capital providing a return on the unamortized balance for the benefit of customers. Further, Entergy Arkansas proposes to flow the benefits of the solar production tax credits to customers through Entergy Arkansas’s formula rate plan, effective with the formula rate plan rates that will go into effect January 1, 2027. Entergy Arkansas’s proposal would result in the benefits of the production tax credits being passed through to customers, if approved, as reductions in revenue requirement evenly over the life of the assets, rather than only during the 10-year period in which the production tax credits are generated. In April 2026 the APSC general staff filed testimony proposing an amortization period of no more than 15 years for the monetized proceeds for the tax credits associated with the West Memphis Solar and Driver Solar facilities. An evidentiary hearing was held in July 2026, but was not completed. The APSC is to set a date to complete the hearing. Special Rate Contract and Arkansas Cypress Solar As discussed in the Form 10-K, in September 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of the Arkansas Cypress Solar facility, a planned 600 MW solar photovoltaic array with a 350 MW battery energy storage system and associated transmission facilities interconnecting at Entergy Arkansas’s White Bluff substation. The estimated cost of the project is $1,602 million. In March 2026 the APSC approved the Arkansas Cypress Solar facility and Entergy Arkansas’s recovery of the costs of the facility through the Generating Arkansas Jobs Act rider. The APSC also ordered implementation of an independent monitor to oversee costs. In April 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of costs. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including the Arkansas Cypress Solar facility, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates. No alternative recommendations were made by the other parties. The facility is expected to be in service by the end of 2028. Filings with the LPSC (Entergy Louisiana) Retail Rates Resilience Plan Cost Recovery Rider In December 2022, Entergy Louisiana filed an application with the LPSC seeking a public interest finding regarding Phase I of Entergy Louisiana’s Future Ready resilience plan and approval of a rider mechanism to recover the program’s costs. Phase I in the December 2022 application reflected the first five years of a ten-year resilience plan and included investment of approximately $5 billion, including hardening investment, transmission dead-end structures, enhanced vegetation management, and telecommunications improvement. In April 2024 the LPSC approved a framework which includes an initial five-year resilience plan providing for an investment of approximately $1.9 billion with cost recovery via a forward-looking rider with semi-annual true-ups. The plan is subject to specified reporting requirements and includes a performance review of the hardened assets. The LPSC order approving the framework does not include any restrictions on Entergy Louisiana’s ability to file applications for approval of additional investments in resilience. In January 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $40.4 million, or $38.9 million in incremental annual revenues from Entergy Louisiana’s first semi-annual filing in July 2024, for projects expected to be placed in service during the rate-effective period of March 2025 through August 2025. In February 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $50.2 million, or $9.8 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2025 through February 2026. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $5.6 million to be implemented in the January 2026 semi-annual filing. In August 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In January 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $101.8 million, or $51.6 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of March 2026 through August 2026. Additionally, Entergy Louisiana’s true-up filing included an over-recovery totaling $16.6 million to be implemented in the July 2026 semi-annual filing. In February 2026 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $114.2 million, or $12.4 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2026 through February 2027. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $2.5 million to be implemented in the January 2027 semi-annual filing. The LPSC staff is reviewing the filed rider rates. Vegetation Management Rider In November 2025 the LPSC staff issued notice of its initiation of a rulemaking to implement a vegetation management pilot program for LPSC jurisdictional electric utilities. The pilot program would be voluntary and would allow utilities to establish a rider for distribution vegetation management for up to 100% of the utility’s prior calendar year vegetation management spending. The rider may not exceed 1% of a customer’s bill, and the utility would be required to maintain its prior calendar year level of spending on vegetation management as reflected in its base rates or formula rate plan. In February 2026 the LPSC staff filed a report and recommendation along with a proposed final rule providing for the adoption of the pilot program consistent with the terms outlined in the original notice. In March 2026 the LPSC voted to accept the LPSC staff’s recommendation and adopt the proposed pilot program as presented. In April 2026, Entergy Louisiana filed its vegetation management rider for the rate-effective period of May 2026 through December 2026, which included a revenue requirement of $20 million for incremental spending on distribution vegetation management above the prior calendar year level of spending on vegetation management. 2025 Formula Rate Plan Filing In June 2026, Entergy Louisiana filed its formula rate plan evaluation report for its 2025 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 2025, the formula produced an earned return on equity of 9.63%, which falls within the established bandwidth and therefore results in no adjustment to base rider formula rate plan revenue. Additional changes in formula rate plan revenue include: (1) the removal of approximately $73 million in annual customer credits associated with the global stipulated settlement agreement, which have been fully credited to customers in accordance with the agreement; (2) a reduction in customer credits through the tax adjustment mechanism, attributable to the return of Entergy Louisiana’s over-collection of income tax expense associated with Louisiana state tax law changes effective in 2025 and the expiration of certain ad valorem exemptions; (3) increases in transmission and distribution plant in service, as recognized through the transmission and distribution recovery mechanisms, including restoration costs from Winter Storm Fern, for which Entergy Louisiana does not intend to seek relief or exception to the formula rate plan; (4) increases to the additional capacity mechanism; and (5) the final phase-in of additional nuclear depreciation expense, in accordance with the global stipulated settlement agreement. See Note 2 to the financial statements in the Form 10-K for discussion of the global stipulated settlement agreement. Collectively, these factors contributed to a net increase of $222 million in formula rate plan revenue for the period. Subject to LPSC review, the resulting changes from the 2025 formula rate plan evaluation report will become effective for bills rendered during the first billing cycle of September 2026, subject to refund. Request for Extension of Formula Rate Plan In June 2026, Entergy Louisiana submitted a motion requesting the LPSC approve a one-year extension of its current formula rate plan, with all material provisions left unchanged, including the allowed return on common equity of 9.7% with a bandwidth of 40 basis points above and below the midpoint. Entergy Louisiana has requested LPSC action on the proposed extension by August 2026. River Bend Deregulated Asset Plan Filing In September 2025, Entergy Louisiana filed an application seeking LPSC approval to recover from customers, prospectively, approximately $49 million in annual revenues associated with the Louisiana retail deregulated portion of River Bend. Costs associated with the deregulated portion of River Bend have historically been excluded from retail ratemaking as a result of a 1988 LPSC decision. Instead, Entergy Louisiana has been allowed by the LPSC to either recover 4.6 cents per kWh for the power generated from that portion of the plant, or sell the power into the applicable market (subject to certain restrictions). The filing presents evidence that River Bend is a cost-effective and prudent source of needed baseload supply with value to Entergy Louisiana customers and seeks to recover the previously excluded costs, on a prospective basis. In March 2026 the LPSC staff and certain intervenors filed direct testimony recommending that the LPSC deny Entergy Louisiana’s application. The LPSC staff’s testimony further recommends that, if the LPSC were to grant any relief, notwithstanding the LPSC staff’s recommendation, such relief should be limited to allowing only prospective capital additions at River Bend to be included in Entergy Louisiana’s customer rates. Entergy Louisiana’s rebuttal testimony is due in August 2026. A hearing is scheduled for January 2027. Filings with the MPSC (Entergy Mississippi) Retail Rates 2026 Formula Rate Plan Filing In February 2026, Entergy Mississippi submitted its formula rate plan 2026 test year filing and 2025 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2025 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2026 calendar year to also be within the formula rate plan bandwidth. The 2026 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2025 look-back filing compared actual 2025 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 $293 thousand to reflect one outside-the-bandwidth change, a true-up of demand side management costs. In June 2026, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2026 test year filing, with the exception of immaterial adjustments to certain operations and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2026, resulting in no change in formula rate plan revenues for 2026. Pursuant to the stipulation, Entergy Mississippi’s 2025 look-back filing reflected an earned return on rate base of 8.10%, which also resulted in no change in formula rate plan revenues for 2025. In addition, the stipulation included the recovery of the outside-the-bandwidth change discussed above as well as the ratemaking treatment of certain customer contributions, the mechanism for recovery of the benefits of nuclear production tax credits, and the realignment of the first project from the interim facilities rate adjustment to the formula rate plan. In June 2026 the MPSC approved the joint stipulation with rates effective in July 2026. See Note 10 to the financial statements herein for further discussion of the mechanism for recovery of the benefits of nuclear production tax credits included in the joint stipulation. Filings with the City Council (Entergy New Orleans) Retail Rates 2026 Formula Rate Plan Filing In April 2026, Entergy New Orleans submitted to the City Council its formula rate plan 2025 test year filing. The 2025 evaluation report produced an earned return on equity of 7.55% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in an increase in rates of $16.6 million. The increase in rates is driven, in part, by an increase in plant in service, as well as the cost of known and measurable capital additions. The increase is also driven by a decrease in total revenues due to a decline in kWh sales. The filing is subject to a 75-day review and discovery period followed by a 25-day period to resolve any disputes among the parties. In July 2026 the City Council’s advisors issued a report seeking a reduction in Entergy New Orleans’s requested formula rate plan revenues of approximately $4.4 million due to certain proposed cost realignments, imputation of revenues, and disallowances. The City Council’s advisors also recommended that Entergy New Orleans be permitted to collect $20 million over five years beginning in September 2026 to recover amounts that it might be required to pay Entergy Louisiana and Entergy Arkansas pursuant to a FERC order issued in June 2026, relating to an alleged MSS-4 replacement tariff (MSS-4R) violation. However, the FERC order is unclear on its face, and the specific amount of a payment, if any, is unknown. Requests for rehearing and clarification of the FERC order are pending. See “MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding” below for additional discussion of the FERC order. If any rate adjustments are not resolved, the City Council would set a procedural schedule to resolve such disputes. A response by Entergy New Orleans to the advisors’ report is due in August 2026. Resulting rates will be effective with the first billing cycle of September 2026 pursuant to the formula rate plan tariff. Request for Extension of Formula Rate Plan In July 2026, Entergy New Orleans submitted a motion requesting the City Council approve a four-year extension of its current formula rate plan, with all material provisions left unchanged, including the authorized return on equity of 9.35% with a bandwidth of 50 basis points above and below the midpoint. Entergy New Orleans has requested City Council action on the proposed extension by August 2026. Filings with the PUCT and Texas Cities (Entergy Texas) Retail Rates Distribution Cost Recovery Factor (DCRF) Rider In April 2026, 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 $112.5 million annually, or $20.4 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2025 and December 31, 2025. In July 2026 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after July 8, 2026. Transmission Cost Recovery Factor (TCRF) Rider As discussed in the Form 10-K, in October 2025, Entergy Texas filed with the PUCT a request to amend its TCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $30.3 million annually, or $20.6 million in incremental annual revenues beyond Entergy Texas’s then-effective TCRF rider based on its capital invested in transmission between July 1, 2024 and June 30, 2025 and changes in other transmission charges. In April 2026 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 6, 2026. Generation Cost Recovery Rider In March 2026, Entergy Texas filed an application to establish a generation cost recovery rider to begin recovering a return of and on its capital investment in the Orange County Advanced Power Station. The proposed generation cost recovery rider, which includes Entergy Texas’s capital invested in generation for the Orange County Advanced Power Station through December 31, 2025, is designed to collect approximately $150.4 million annually from Entergy Texas’s retail customers. By statute, the proposed generation cost recovery rider rates are to become effective when the Orange County Advanced Power Station is placed into service, which is expected in third quarter 2026. In July 2026 the ALJ with the State Office of Administrative Hearings approved a proposed procedural schedule that includes a hearing on the merits in September 2026 and provides for interim rates to become effective for usage on and after the Orange County Advanced Power Station in-service date, to the extent final rates are not in place by that time. Capacity Cost Recovery Rider (CCRR) In May 2026, Entergy Texas filed with the PUCT a request to establish a new CCRR. The proposed CCRR is designed to collect approximately $58 million annually from Entergy Texas’s retail customers based on Entergy Texas’s eligible capacity-related costs and revenues for the 12 months beginning June 1, 2026. The eligible capacity-related costs and revenues are associated with Entergy Texas’s participation in MISO’s annual planning resource auction. In July 2026 the PUCT approved the CCRR, consistent with Entergy Texas’s as-filed request, and rates became effective on July 10, 2026. Entergy Arkansas Opportunity Sales Proceeding See Note 2 to the financial statements in the Form 10-K for discussion of the Entergy Arkansas opportunity sales proceeding. Complaints Against System Energy See Note 2 to the financial statements in the Form 10-K for information regarding complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. Unit Power Sales Agreement See Note 2 to the financial statements in the Form 10-K for discussion of the Unit Power Sales Agreement. The following is an update to that discussion. Pension Costs Amendment Proceeding As discussed in the Form 10-K, in October 2021, System Energy submitted to the FERC proposed amendments to the Unit Power Sales Agreement to include in rate base the prepaid and accrued pension costs associated with System Energy’s qualified pension plans. In November 2025 the FERC issued an order approving System Energy’s proposed prepaid and accrued pension recovery mechanism. System Energy has been utilizing this methodology in billings since December 1, 2022 and will continue to utilize it going forward. As a result of the FERC’s order, System Energy did not owe any refunds. In December 2025 the APSC filed a request for rehearing of the November 2025 order. In January 2026 the FERC denied the APSC’s rehearing request by operation of law. In May 2026 the FERC issued a follow-up substantive order denying the APSC’s rehearing and sustaining its finding that no refunds are owed. 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-4R net operating loss carryforward proceeding. The following is an update to that discussion. As discussed in the Form 10-K, in October 2021 the LPSC filed a complaint with the FERC alleging that Entergy Services improperly excluded net operating loss carryforward accumulated deferred income taxes (NOLC ADIT) from MSS-4R rates in the period before March 20, 2021. The LPSC argued that sales from Entergy Louisiana to Entergy Texas and Entergy New Orleans were charged at rates lower than they otherwise should have been, and it accordingly seeks surcharges for the period prior to March 20, 2021. The FERC set the complaint for hearing procedures and subsequently the hearing for this complaint proceeding was consolidated with the hearing procedures for Entergy Services’ January 2021 NOLC ADIT filing. Testimony was filed by parties in 2023, and the hearing before a FERC ALJ was concluded in February 2024. In June 2024, the FERC ALJ issued an initial decision addressing three major issues: (1) whether Entergy Services’ proposed prospective inclusion and allocation of NOLC ADIT in MSS-4R rates using a modified with-and-without methodology is just and reasonable; (2) whether Entergy Services correctly calculated excess and deficient accumulated deferred income taxes in accordance with the terms of a prior settlement; and (3) whether NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the January 2021 MSS-4R filing. With respect to issues (1) and (2), the presiding ALJ concluded that Entergy Services’ proposed methodology for allocating and including NOLC ADIT in MSS-4R rates was just and reasonable and that Entergy Services correctly performed the excess and deficient accumulated deferred income taxes calculations. With respect to issue (3), however, the presiding ALJ agreed with the LPSC that NOLC ADIT should have been included in MSS-4R rates since September 1, 2016, and as a result, the presiding ALJ ordered that Entergy Louisiana and Entergy Arkansas recalculate bills for the period of September 1, 2016 through November 11, 2023 with surcharges expected to be due to those operating companies from the purchasing operating companies, Entergy New Orleans, Entergy Texas, and Entergy Louisiana (for some Entergy Arkansas sales). The presiding ALJ also ordered Entergy Services to pay the interest owed to Entergy Louisiana on these surcharges. The surcharge methodology that the presiding ALJ recommended in connection with issue (3) was not supported by any participant in the hearing. As part of their exceptions to the initial decision, all parties to the proceeding opposed the use of the ALJ’s methodology, except for the FERC trial staff, which took no position. During the hearing, the LPSC and the FERC trial staff advocated that the alleged tariff violation should be remedied by the application of Entergy Services’ January 2021 proposed methodology. All other parties, including the PUCT, the City Council, and Entergy Services, opposed any surcharges for the period prior to the March 20, 2021 effective date of the January 2021 filing. Entergy Services disputed the presiding ALJ's rulings on issue (3) and filed exceptions to these rulings in July 2024. In June 2026 the FERC issued its opinion largely affirming the initial decision. Specifically, the FERC found the historic exclusion of NOLC ADIT from MSS-4R rates was a tariff violation and ordered Entergy Louisiana and Entergy Arkansas to provide refunds and/or surcharges, as appropriate, for the period from September 1, 2016 through November 12, 2023 for sales by Entergy Louisiana and for the period December 19, 2013 until May 13, 2024 for sales by Entergy Arkansas. The FERC also ordered the relevant operating company to pay interest on the amounts owed. In July 2026, Entergy Services, along with the LPSC, the City Council, and the PUCT, filed for rehearing and clarification of the FERC’s order. Entergy Services continues to dispute that the NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the tariff amendment filing. Moreover, because of ambiguity in the order and the pending rehearing and clarification requests, it is unclear whether Entergy Arkansas and Entergy Louisiana as sellers will receive surcharges or have to provide refunds. Specifically, there is a lack of clarity as to whether plant-related liability accumulated deferred income taxes must be included in calculating refunds/surcharges. Entergy Services also identified a lack of clarity regarding including the nuclear decommissioning liability deduction in the NOLC ADIT calculation. Depending on the guidance issued by the FERC in response to the request for rehearing and clarification of its June 2026 order, each of the affected Entergy operating companies could either receive material refunds or owe material surcharges. As such, any amounts payable or receivable between the Entergy operating companies that may result from the order are not reasonably estimable as of June 30, 2026. MSS-4 Replacement Tariff – River Bend 70 Depreciation LPSC Complaint In May 2026 the LPSC filed a complaint with the FERC alleging that Entergy Texas owes surcharges to Entergy Louisiana because the depreciation rates used in the MSS-4R for the River Bend 70 sales of capacity and energy were based on a directive of the PUCT for the period from September 1, 2016 to December 31, 2025. The LPSC quantifies the potential surcharge as $100 million, inclusive of interest. Entergy Services disputes that any surcharges are due from Entergy Texas to Entergy Louisiana. In June 2026, Entergy Services filed a motion to dismiss and answer to the complaint submitted by the LPSC. Joint Targeted Interconnection Queue Cost Allocation Dispute In April 2026, MISO submitted to the FERC an unexecuted agreement proposing to assign to Entergy Texas (in its capacity as the owner of the Legend Power Station) costs associated with the MISO and Southwest Power Pool Joint Targeted Interconnection Queue. Entergy Texas estimates that MISO’s proposed cost assignment would result in total charges of approximately $112 million, paid over twenty years beginning in 2031. In May 2026, Entergy Texas filed a protest to the agreement, as well as a separate complaint at the FERC, arguing that the proposed cost allocation is not just and reasonable. In June 2026 the FERC issued a deficiency notice to MISO. In July 2026, MISO and Southwest Power Pool filed answers to the complaint, and MISO filed an answer to the deficiency letter. Protests and comments in response to MISO’s answer to the deficiency letter are due in August 2026.

Public Utilities Disclosure [Text Block]	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 2026, 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 $0.01333 per kWh to $0.01508 per kWh. The primary reason for the rate increase was an under-recovered balance as a result of higher natural gas prices in 2025. Based on circumstances related to ANO 2’s refueling outage, Entergy Arkansas made an adjustment to projected energy costs to phase-in the rate increase gradually. The redetermined rate of $0.01508 per kWh became effective with the first billing cycle in April 2026 through the normal operation of the tariff. Entergy Louisiana As discussed in the Form 10-K, in June 2025 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings (for Entergy Louisiana’s gas operations). The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from January 2023 through June 2025. The LPSC staff issued its audit report in March 2026. The next step is for the LPSC to issue its final report, but there is no deadline or timing requirement associated with the issuance of the final report. In February 2026, Entergy Louisiana, in its monthly filing to update its fuel adjustment clause, requested to defer approximately $141.9 million of fuel costs incurred in January 2026 that were primarily attributable to the effects of Winter Storm Fern, consistent with the LPSC’s general order approved at its February 2026 meeting permitting temporary modifications to the LPSC’s fuel adjustment clause general order. The filing proposed to defer the recovery of these fuel costs over a four-month period from March 2026 through June 2026 to mitigate the customer bill impacts of these fuel costs. In March 2026 the LPSC issued a special order delegating authority to the LPSC executive secretary to review and approve utility-specific requests for deferral of fuel costs from Winter Storm Fern, subject to audit as per the LPSC’s fuel clause general order. In April 2026 the LPSC executive secretary approved Entergy Louisiana’s request for deferral. In April 2026 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2023 through 2025. Discovery is ongoing, and no audit report has been filed. 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 2026 Base Rate Case In February 2026, Entergy Arkansas filed with the APSC a general change in rates, charges, and tariffs. The filing requested a base rate increase to recover a base rate revenue deficiency of $44.6 million and notified the APSC of Entergy Arkansas’s intent to implement a forward test year formula rate plan pursuant to Arkansas legislation passed in 2015. The primary drivers of the revenue deficiency were increased depreciation expense and the impact of net capital additions. Additionally, the filing requested a 9.90% return on common equity and increased depreciation rates as the result of a depreciation study. In March 2026 the APSC issued an order suspending the proposed rates and tariffs filed by Entergy Arkansas. In June 2026 the APSC established a procedural schedule with an evidentiary hearing scheduled to begin in November 2026, and in July 2026 a number of intervenors moved to modify the schedule to conduct additional discovery. Entergy Arkansas opposed the motion in part based on the voluminous discovery conducted to date. 2026 Formula Rate Plan Filing In July 2026, Entergy Arkansas filed with the APSC its 2026 formula rate plan filing to set its formula rate for the 2027 calendar year. The filing contained an evaluation of Entergy Arkansas’s earnings and a netting adjustment for the 2025 historical year. The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2025 historical year was 8.8%, resulting in a $47.2 million formula rate plan revenue increase to produce a 9.65% earned rate of return on common equity. When combined with 2025 historical year formula rate plan revenues of $56.0 million, the total proposed revenue change for the 2025 historical year netting adjustment is a reduction of $8.8 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. Entergy Arkansas’s revenue requirement in this filing did not exceed the constraint. In second quarter 2026, Entergy Arkansas recorded a regulatory liability of $8.8 million to reflect the amount of the 2025 historical year netting adjustment that it collected from customers during the 2025 rate effective period. Generating Arkansas Jobs Act Rider In March 2026, Entergy Arkansas filed its first annual update to the strategic investment recovery rider, requesting recovery of $110.4 million of financing costs during construction of generation and transmission strategic investments related to Ironwood Power Station, Jefferson Power Station, and the Arkansas Cypress Solar facility. The revised rates were requested to be effective with the first billing cycle of June 2026. In April 2026 the APSC general staff filed testimony arguing that the APSC had not issued an order designating Ironwood Power Station as a strategic investment and that related costs should therefore be removed from the annual update. Also in April 2026, Entergy Arkansas filed testimony asserting that the APSC general staff’s position is contrary to the plain language of the statute, which includes an exception for facilities like Ironwood Power Station that were certified by the APSC within a certain timeframe. A hearing was held in April 2026. In June 2026 the APSC approved Entergy Arkansas’s annual update, and rates became effective June 4, 2026. Production Tax Credit Tariffs As discussed in Note 3 to the financial statements in the Form 10-K, in January 2026 the APSC opened a docket to investigate the sale of Entergy Arkansas’s nuclear production tax credits and the appropriate ratemaking treatment of production tax credits for all of Entergy Arkansas’s eligible resources, including how the proceeds of any sales should flow through to customers. For nuclear production tax credits, Entergy Arkansas proposed a nuclear production tax credit rider, which would provide for the immediate flow through to customers of the weighted average cost of capital return on the net proceeds of the monetized nuclear production tax credits. Recognizing that the timing and determination from the IRS is uncertain, the nuclear production tax credit rider also proposes that, if there is an unfavorable IRS determination, Entergy Arkansas would collect applicable costs from customers. As directed by the APSC, in February 2026, Entergy Arkansas submitted a compliance filing to the APSC verifying the status of the solar production tax credits. The filing also verified that the net proceeds from the sale of the nuclear production tax credits were recorded in FERC accounts that are accruing a return for customers’ benefit at a rate that is above the customer deposit rate. Subsequently, in March 2026, Entergy Arkansas filed testimony setting forth its proposal for the solar production tax credits. Specifically, Entergy Arkansas requested the same ratemaking treatment for all of the solar facilities that the APSC already approved for Walnut Bend (i.e., the total net monetized proceeds from production tax credits expected to be generated over the first ten years of a solar facility’s operation are estimated and then amortized over the expected useful life of the asset, which is typically 30 years). Additionally, consistent with prior orders for these resources, the regulatory liabilities associated with the net cash proceeds from monetized solar production tax credits will be included in Entergy Arkansas’s calculation of its weighted average cost of capital providing a return on the unamortized balance for the benefit of customers. Further, Entergy Arkansas proposes to flow the benefits of the solar production tax credits to customers through Entergy Arkansas’s formula rate plan, effective with the formula rate plan rates that will go into effect January 1, 2027. Entergy Arkansas’s proposal would result in the benefits of the production tax credits being passed through to customers, if approved, as reductions in revenue requirement evenly over the life of the assets, rather than only during the 10-year period in which the production tax credits are generated. In April 2026 the APSC general staff filed testimony proposing an amortization period of no more than 15 years for the monetized proceeds for the tax credits associated with the West Memphis Solar and Driver Solar facilities. An evidentiary hearing was held in July 2026, but was not completed. The APSC is to set a date to complete the hearing. Special Rate Contract and Arkansas Cypress Solar As discussed in the Form 10-K, in September 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of the Arkansas Cypress Solar facility, a planned 600 MW solar photovoltaic array with a 350 MW battery energy storage system and associated transmission facilities interconnecting at Entergy Arkansas’s White Bluff substation. The estimated cost of the project is $1,602 million. In March 2026 the APSC approved the Arkansas Cypress Solar facility and Entergy Arkansas’s recovery of the costs of the facility through the Generating Arkansas Jobs Act rider. The APSC also ordered implementation of an independent monitor to oversee costs. In April 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of costs. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including the Arkansas Cypress Solar facility, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates. No alternative recommendations were made by the other parties. The facility is expected to be in service by the end of 2028. Filings with the LPSC (Entergy Louisiana) Retail Rates Resilience Plan Cost Recovery Rider In December 2022, Entergy Louisiana filed an application with the LPSC seeking a public interest finding regarding Phase I of Entergy Louisiana’s Future Ready resilience plan and approval of a rider mechanism to recover the program’s costs. Phase I in the December 2022 application reflected the first five years of a ten-year resilience plan and included investment of approximately $5 billion, including hardening investment, transmission dead-end structures, enhanced vegetation management, and telecommunications improvement. In April 2024 the LPSC approved a framework which includes an initial five-year resilience plan providing for an investment of approximately $1.9 billion with cost recovery via a forward-looking rider with semi-annual true-ups. The plan is subject to specified reporting requirements and includes a performance review of the hardened assets. The LPSC order approving the framework does not include any restrictions on Entergy Louisiana’s ability to file applications for approval of additional investments in resilience. In January 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $40.4 million, or $38.9 million in incremental annual revenues from Entergy Louisiana’s first semi-annual filing in July 2024, for projects expected to be placed in service during the rate-effective period of March 2025 through August 2025. In February 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $50.2 million, or $9.8 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2025 through February 2026. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $5.6 million to be implemented in the January 2026 semi-annual filing. In August 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In January 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $101.8 million, or $51.6 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of March 2026 through August 2026. Additionally, Entergy Louisiana’s true-up filing included an over-recovery totaling $16.6 million to be implemented in the July 2026 semi-annual filing. In February 2026 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $114.2 million, or $12.4 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2026 through February 2027. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $2.5 million to be implemented in the January 2027 semi-annual filing. The LPSC staff is reviewing the filed rider rates. Vegetation Management Rider In November 2025 the LPSC staff issued notice of its initiation of a rulemaking to implement a vegetation management pilot program for LPSC jurisdictional electric utilities. The pilot program would be voluntary and would allow utilities to establish a rider for distribution vegetation management for up to 100% of the utility’s prior calendar year vegetation management spending. The rider may not exceed 1% of a customer’s bill, and the utility would be required to maintain its prior calendar year level of spending on vegetation management as reflected in its base rates or formula rate plan. In February 2026 the LPSC staff filed a report and recommendation along with a proposed final rule providing for the adoption of the pilot program consistent with the terms outlined in the original notice. In March 2026 the LPSC voted to accept the LPSC staff’s recommendation and adopt the proposed pilot program as presented. In April 2026, Entergy Louisiana filed its vegetation management rider for the rate-effective period of May 2026 through December 2026, which included a revenue requirement of $20 million for incremental spending on distribution vegetation management above the prior calendar year level of spending on vegetation management. 2025 Formula Rate Plan Filing In June 2026, Entergy Louisiana filed its formula rate plan evaluation report for its 2025 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 2025, the formula produced an earned return on equity of 9.63%, which falls within the established bandwidth and therefore results in no adjustment to base rider formula rate plan revenue. Additional changes in formula rate plan revenue include: (1) the removal of approximately $73 million in annual customer credits associated with the global stipulated settlement agreement, which have been fully credited to customers in accordance with the agreement; (2) a reduction in customer credits through the tax adjustment mechanism, attributable to the return of Entergy Louisiana’s over-collection of income tax expense associated with Louisiana state tax law changes effective in 2025 and the expiration of certain ad valorem exemptions; (3) increases in transmission and distribution plant in service, as recognized through the transmission and distribution recovery mechanisms, including restoration costs from Winter Storm Fern, for which Entergy Louisiana does not intend to seek relief or exception to the formula rate plan; (4) increases to the additional capacity mechanism; and (5) the final phase-in of additional nuclear depreciation expense, in accordance with the global stipulated settlement agreement. See Note 2 to the financial statements in the Form 10-K for discussion of the global stipulated settlement agreement. Collectively, these factors contributed to a net increase of $222 million in formula rate plan revenue for the period. Subject to LPSC review, the resulting changes from the 2025 formula rate plan evaluation report will become effective for bills rendered during the first billing cycle of September 2026, subject to refund. Request for Extension of Formula Rate Plan In June 2026, Entergy Louisiana submitted a motion requesting the LPSC approve a one-year extension of its current formula rate plan, with all material provisions left unchanged, including the allowed return on common equity of 9.7% with a bandwidth of 40 basis points above and below the midpoint. Entergy Louisiana has requested LPSC action on the proposed extension by August 2026. River Bend Deregulated Asset Plan Filing In September 2025, Entergy Louisiana filed an application seeking LPSC approval to recover from customers, prospectively, approximately $49 million in annual revenues associated with the Louisiana retail deregulated portion of River Bend. Costs associated with the deregulated portion of River Bend have historically been excluded from retail ratemaking as a result of a 1988 LPSC decision. Instead, Entergy Louisiana has been allowed by the LPSC to either recover 4.6 cents per kWh for the power generated from that portion of the plant, or sell the power into the applicable market (subject to certain restrictions). The filing presents evidence that River Bend is a cost-effective and prudent source of needed baseload supply with value to Entergy Louisiana customers and seeks to recover the previously excluded costs, on a prospective basis. In March 2026 the LPSC staff and certain intervenors filed direct testimony recommending that the LPSC deny Entergy Louisiana’s application. The LPSC staff’s testimony further recommends that, if the LPSC were to grant any relief, notwithstanding the LPSC staff’s recommendation, such relief should be limited to allowing only prospective capital additions at River Bend to be included in Entergy Louisiana’s customer rates. Entergy Louisiana’s rebuttal testimony is due in August 2026. A hearing is scheduled for January 2027. Filings with the MPSC (Entergy Mississippi) Retail Rates 2026 Formula Rate Plan Filing In February 2026, Entergy Mississippi submitted its formula rate plan 2026 test year filing and 2025 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2025 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2026 calendar year to also be within the formula rate plan bandwidth. The 2026 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2025 look-back filing compared actual 2025 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 $293 thousand to reflect one outside-the-bandwidth change, a true-up of demand side management costs. In June 2026, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2026 test year filing, with the exception of immaterial adjustments to certain operations and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2026, resulting in no change in formula rate plan revenues for 2026. Pursuant to the stipulation, Entergy Mississippi’s 2025 look-back filing reflected an earned return on rate base of 8.10%, which also resulted in no change in formula rate plan revenues for 2025. In addition, the stipulation included the recovery of the outside-the-bandwidth change discussed above as well as the ratemaking treatment of certain customer contributions, the mechanism for recovery of the benefits of nuclear production tax credits, and the realignment of the first project from the interim facilities rate adjustment to the formula rate plan. In June 2026 the MPSC approved the joint stipulation with rates effective in July 2026. See Note 10 to the financial statements herein for further discussion of the mechanism for recovery of the benefits of nuclear production tax credits included in the joint stipulation. Filings with the City Council (Entergy New Orleans) Retail Rates 2026 Formula Rate Plan Filing In April 2026, Entergy New Orleans submitted to the City Council its formula rate plan 2025 test year filing. The 2025 evaluation report produced an earned return on equity of 7.55% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in an increase in rates of $16.6 million. The increase in rates is driven, in part, by an increase in plant in service, as well as the cost of known and measurable capital additions. The increase is also driven by a decrease in total revenues due to a decline in kWh sales. The filing is subject to a 75-day review and discovery period followed by a 25-day period to resolve any disputes among the parties. In July 2026 the City Council’s advisors issued a report seeking a reduction in Entergy New Orleans’s requested formula rate plan revenues of approximately $4.4 million due to certain proposed cost realignments, imputation of revenues, and disallowances. The City Council’s advisors also recommended that Entergy New Orleans be permitted to collect $20 million over five years beginning in September 2026 to recover amounts that it might be required to pay Entergy Louisiana and Entergy Arkansas pursuant to a FERC order issued in June 2026, relating to an alleged MSS-4 replacement tariff (MSS-4R) violation. However, the FERC order is unclear on its face, and the specific amount of a payment, if any, is unknown. Requests for rehearing and clarification of the FERC order are pending. See “MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding” below for additional discussion of the FERC order. If any rate adjustments are not resolved, the City Council would set a procedural schedule to resolve such disputes. A response by Entergy New Orleans to the advisors’ report is due in August 2026. Resulting rates will be effective with the first billing cycle of September 2026 pursuant to the formula rate plan tariff. Request for Extension of Formula Rate Plan In July 2026, Entergy New Orleans submitted a motion requesting the City Council approve a four-year extension of its current formula rate plan, with all material provisions left unchanged, including the authorized return on equity of 9.35% with a bandwidth of 50 basis points above and below the midpoint. Entergy New Orleans has requested City Council action on the proposed extension by August 2026. Filings with the PUCT and Texas Cities (Entergy Texas) Retail Rates Distribution Cost Recovery Factor (DCRF) Rider In April 2026, 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 $112.5 million annually, or $20.4 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2025 and December 31, 2025. In July 2026 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after July 8, 2026. Transmission Cost Recovery Factor (TCRF) Rider As discussed in the Form 10-K, in October 2025, Entergy Texas filed with the PUCT a request to amend its TCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $30.3 million annually, or $20.6 million in incremental annual revenues beyond Entergy Texas’s then-effective TCRF rider based on its capital invested in transmission between July 1, 2024 and June 30, 2025 and changes in other transmission charges. In April 2026 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 6, 2026. Generation Cost Recovery Rider In March 2026, Entergy Texas filed an application to establish a generation cost recovery rider to begin recovering a return of and on its capital investment in the Orange County Advanced Power Station. The proposed generation cost recovery rider, which includes Entergy Texas’s capital invested in generation for the Orange County Advanced Power Station through December 31, 2025, is designed to collect approximately $150.4 million annually from Entergy Texas’s retail customers. By statute, the proposed generation cost recovery rider rates are to become effective when the Orange County Advanced Power Station is placed into service, which is expected in third quarter 2026. In July 2026 the ALJ with the State Office of Administrative Hearings approved a proposed procedural schedule that includes a hearing on the merits in September 2026 and provides for interim rates to become effective for usage on and after the Orange County Advanced Power Station in-service date, to the extent final rates are not in place by that time. Capacity Cost Recovery Rider (CCRR) In May 2026, Entergy Texas filed with the PUCT a request to establish a new CCRR. The proposed CCRR is designed to collect approximately $58 million annually from Entergy Texas’s retail customers based on Entergy Texas’s eligible capacity-related costs and revenues for the 12 months beginning June 1, 2026. The eligible capacity-related costs and revenues are associated with Entergy Texas’s participation in MISO’s annual planning resource auction. In July 2026 the PUCT approved the CCRR, consistent with Entergy Texas’s as-filed request, and rates became effective on July 10, 2026. Entergy Arkansas Opportunity Sales Proceeding See Note 2 to the financial statements in the Form 10-K for discussion of the Entergy Arkansas opportunity sales proceeding. Complaints Against System Energy See Note 2 to the financial statements in the Form 10-K for information regarding complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. Unit Power Sales Agreement See Note 2 to the financial statements in the Form 10-K for discussion of the Unit Power Sales Agreement. The following is an update to that discussion. Pension Costs Amendment Proceeding As discussed in the Form 10-K, in October 2021, System Energy submitted to the FERC proposed amendments to the Unit Power Sales Agreement to include in rate base the prepaid and accrued pension costs associated with System Energy’s qualified pension plans. In November 2025 the FERC issued an order approving System Energy’s proposed prepaid and accrued pension recovery mechanism. System Energy has been utilizing this methodology in billings since December 1, 2022 and will continue to utilize it going forward. As a result of the FERC’s order, System Energy did not owe any refunds. In December 2025 the APSC filed a request for rehearing of the November 2025 order. In January 2026 the FERC denied the APSC’s rehearing request by operation of law. In May 2026 the FERC issued a follow-up substantive order denying the APSC’s rehearing and sustaining its finding that no refunds are owed. 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-4R net operating loss carryforward proceeding. The following is an update to that discussion. As discussed in the Form 10-K, in October 2021 the LPSC filed a complaint with the FERC alleging that Entergy Services improperly excluded net operating loss carryforward accumulated deferred income taxes (NOLC ADIT) from MSS-4R rates in the period before March 20, 2021. The LPSC argued that sales from Entergy Louisiana to Entergy Texas and Entergy New Orleans were charged at rates lower than they otherwise should have been, and it accordingly seeks surcharges for the period prior to March 20, 2021. The FERC set the complaint for hearing procedures and subsequently the hearing for this complaint proceeding was consolidated with the hearing procedures for Entergy Services’ January 2021 NOLC ADIT filing. Testimony was filed by parties in 2023, and the hearing before a FERC ALJ was concluded in February 2024. In June 2024, the FERC ALJ issued an initial decision addressing three major issues: (1) whether Entergy Services’ proposed prospective inclusion and allocation of NOLC ADIT in MSS-4R rates using a modified with-and-without methodology is just and reasonable; (2) whether Entergy Services correctly calculated excess and deficient accumulated deferred income taxes in accordance with the terms of a prior settlement; and (3) whether NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the January 2021 MSS-4R filing. With respect to issues (1) and (2), the presiding ALJ concluded that Entergy Services’ proposed methodology for allocating and including NOLC ADIT in MSS-4R rates was just and reasonable and that Entergy Services correctly performed the excess and deficient accumulated deferred income taxes calculations. With respect to issue (3), however, the presiding ALJ agreed with the LPSC that NOLC ADIT should have been included in MSS-4R rates since September 1, 2016, and as a result, the presiding ALJ ordered that Entergy Louisiana and Entergy Arkansas recalculate bills for the period of September 1, 2016 through November 11, 2023 with surcharges expected to be due to those operating companies from the purchasing operating companies, Entergy New Orleans, Entergy Texas, and Entergy Louisiana (for some Entergy Arkansas sales). The presiding ALJ also ordered Entergy Services to pay the interest owed to Entergy Louisiana on these surcharges. The surcharge methodology that the presiding ALJ recommended in connection with issue (3) was not supported by any participant in the hearing. As part of their exceptions to the initial decision, all parties to the proceeding opposed the use of the ALJ’s methodology, except for the FERC trial staff, which took no position. During the hearing, the LPSC and the FERC trial staff advocated that the alleged tariff violation should be remedied by the application of Entergy Services’ January 2021 proposed methodology. All other parties, including the PUCT, the City Council, and Entergy Services, opposed any surcharges for the period prior to the March 20, 2021 effective date of the January 2021 filing. Entergy Services disputed the presiding ALJ's rulings on issue (3) and filed exceptions to these rulings in July 2024. In June 2026 the FERC issued its opinion largely affirming the initial decision. Specifically, the FERC found the historic exclusion of NOLC ADIT from MSS-4R rates was a tariff violation and ordered Entergy Louisiana and Entergy Arkansas to provide refunds and/or surcharges, as appropriate, for the period from September 1, 2016 through November 12, 2023 for sales by Entergy Louisiana and for the period December 19, 2013 until May 13, 2024 for sales by Entergy Arkansas. The FERC also ordered the relevant operating company to pay interest on the amounts owed. In July 2026, Entergy Services, along with the LPSC, the City Council, and the PUCT, filed for rehearing and clarification of the FERC’s order. Entergy Services continues to dispute that the NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the tariff amendment filing. Moreover, because of ambiguity in the order and the pending rehearing and clarification requests, it is unclear whether Entergy Arkansas and Entergy Louisiana as sellers will receive surcharges or have to provide refunds. Specifically, there is a lack of clarity as to whether plant-related liability accumulated deferred income taxes must be included in calculating refunds/surcharges. Entergy Services also identified a lack of clarity regarding including the nuclear decommissioning liability deduction in the NOLC ADIT calculation. Depending on the guidance issued by the FERC in response to the request for rehearing and clarification of its June 2026 order, each of the affected Entergy operating companies could either receive material refunds or owe material surcharges. As such, any amounts payable or receivable between the Entergy operating companies that may result from the order are not reasonably estimable as of June 30, 2026. MSS-4 Replacement Tariff – River Bend 70 Depreciation LPSC Complaint In May 2026 the LPSC filed a complaint with the FERC alleging that Entergy Texas owes surcharges to Entergy Louisiana because the depreciation rates used in the MSS-4R for the River Bend 70 sales of capacity and energy were based on a directive of the PUCT for the period from September 1, 2016 to December 31, 2025. The LPSC quantifies the potential surcharge as $100 million, inclusive of interest. Entergy Services disputes that any surcharges are due from Entergy Texas to Entergy Louisiana. In June 2026, Entergy Services filed a motion to dismiss and answer to the complaint submitted by the LPSC. Joint Targeted Interconnection Queue Cost Allocation Dispute In April 2026, MISO submitted to the FERC an unexecuted agreement proposing to assign to Entergy Texas (in its capacity as the owner of the Legend Power Station) costs associated with the MISO and Southwest Power Pool Joint Targeted Interconnection Queue. Entergy Texas estimates that MISO’s proposed cost assignment would result in total charges of approximately $112 million, paid over twenty years beginning in 2031. In May 2026, Entergy Texas filed a protest to the agreement, as well as a separate complaint at the FERC, arguing that the proposed cost allocation is not just and reasonable. In June 2026 the FERC issued a deficiency notice to MISO. In July 2026, MISO and Southwest Power Pool filed answers to the complaint, and MISO filed an answer to the deficiency letter. Protests and comments in response to MISO’s answer to the deficiency letter are due in August 2026.

Public Utilities Disclosure [Text Block]	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 2026, 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 $0.01333 per kWh to $0.01508 per kWh. The primary reason for the rate increase was an under-recovered balance as a result of higher natural gas prices in 2025. Based on circumstances related to ANO 2’s refueling outage, Entergy Arkansas made an adjustment to projected energy costs to phase-in the rate increase gradually. The redetermined rate of $0.01508 per kWh became effective with the first billing cycle in April 2026 through the normal operation of the tariff. Entergy Louisiana As discussed in the Form 10-K, in June 2025 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings (for Entergy Louisiana’s gas operations). The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from January 2023 through June 2025. The LPSC staff issued its audit report in March 2026. The next step is for the LPSC to issue its final report, but there is no deadline or timing requirement associated with the issuance of the final report. In February 2026, Entergy Louisiana, in its monthly filing to update its fuel adjustment clause, requested to defer approximately $141.9 million of fuel costs incurred in January 2026 that were primarily attributable to the effects of Winter Storm Fern, consistent with the LPSC’s general order approved at its February 2026 meeting permitting temporary modifications to the LPSC’s fuel adjustment clause general order. The filing proposed to defer the recovery of these fuel costs over a four-month period from March 2026 through June 2026 to mitigate the customer bill impacts of these fuel costs. In March 2026 the LPSC issued a special order delegating authority to the LPSC executive secretary to review and approve utility-specific requests for deferral of fuel costs from Winter Storm Fern, subject to audit as per the LPSC’s fuel clause general order. In April 2026 the LPSC executive secretary approved Entergy Louisiana’s request for deferral. In April 2026 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2023 through 2025. Discovery is ongoing, and no audit report has been filed. 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 2026 Base Rate Case In February 2026, Entergy Arkansas filed with the APSC a general change in rates, charges, and tariffs. The filing requested a base rate increase to recover a base rate revenue deficiency of $44.6 million and notified the APSC of Entergy Arkansas’s intent to implement a forward test year formula rate plan pursuant to Arkansas legislation passed in 2015. The primary drivers of the revenue deficiency were increased depreciation expense and the impact of net capital additions. Additionally, the filing requested a 9.90% return on common equity and increased depreciation rates as the result of a depreciation study. In March 2026 the APSC issued an order suspending the proposed rates and tariffs filed by Entergy Arkansas. In June 2026 the APSC established a procedural schedule with an evidentiary hearing scheduled to begin in November 2026, and in July 2026 a number of intervenors moved to modify the schedule to conduct additional discovery. Entergy Arkansas opposed the motion in part based on the voluminous discovery conducted to date. 2026 Formula Rate Plan Filing In July 2026, Entergy Arkansas filed with the APSC its 2026 formula rate plan filing to set its formula rate for the 2027 calendar year. The filing contained an evaluation of Entergy Arkansas’s earnings and a netting adjustment for the 2025 historical year. The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2025 historical year was 8.8%, resulting in a $47.2 million formula rate plan revenue increase to produce a 9.65% earned rate of return on common equity. When combined with 2025 historical year formula rate plan revenues of $56.0 million, the total proposed revenue change for the 2025 historical year netting adjustment is a reduction of $8.8 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. Entergy Arkansas’s revenue requirement in this filing did not exceed the constraint. In second quarter 2026, Entergy Arkansas recorded a regulatory liability of $8.8 million to reflect the amount of the 2025 historical year netting adjustment that it collected from customers during the 2025 rate effective period. Generating Arkansas Jobs Act Rider In March 2026, Entergy Arkansas filed its first annual update to the strategic investment recovery rider, requesting recovery of $110.4 million of financing costs during construction of generation and transmission strategic investments related to Ironwood Power Station, Jefferson Power Station, and the Arkansas Cypress Solar facility. The revised rates were requested to be effective with the first billing cycle of June 2026. In April 2026 the APSC general staff filed testimony arguing that the APSC had not issued an order designating Ironwood Power Station as a strategic investment and that related costs should therefore be removed from the annual update. Also in April 2026, Entergy Arkansas filed testimony asserting that the APSC general staff’s position is contrary to the plain language of the statute, which includes an exception for facilities like Ironwood Power Station that were certified by the APSC within a certain timeframe. A hearing was held in April 2026. In June 2026 the APSC approved Entergy Arkansas’s annual update, and rates became effective June 4, 2026. Production Tax Credit Tariffs As discussed in Note 3 to the financial statements in the Form 10-K, in January 2026 the APSC opened a docket to investigate the sale of Entergy Arkansas’s nuclear production tax credits and the appropriate ratemaking treatment of production tax credits for all of Entergy Arkansas’s eligible resources, including how the proceeds of any sales should flow through to customers. For nuclear production tax credits, Entergy Arkansas proposed a nuclear production tax credit rider, which would provide for the immediate flow through to customers of the weighted average cost of capital return on the net proceeds of the monetized nuclear production tax credits. Recognizing that the timing and determination from the IRS is uncertain, the nuclear production tax credit rider also proposes that, if there is an unfavorable IRS determination, Entergy Arkansas would collect applicable costs from customers. As directed by the APSC, in February 2026, Entergy Arkansas submitted a compliance filing to the APSC verifying the status of the solar production tax credits. The filing also verified that the net proceeds from the sale of the nuclear production tax credits were recorded in FERC accounts that are accruing a return for customers’ benefit at a rate that is above the customer deposit rate. Subsequently, in March 2026, Entergy Arkansas filed testimony setting forth its proposal for the solar production tax credits. Specifically, Entergy Arkansas requested the same ratemaking treatment for all of the solar facilities that the APSC already approved for Walnut Bend (i.e., the total net monetized proceeds from production tax credits expected to be generated over the first ten years of a solar facility’s operation are estimated and then amortized over the expected useful life of the asset, which is typically 30 years). Additionally, consistent with prior orders for these resources, the regulatory liabilities associated with the net cash proceeds from monetized solar production tax credits will be included in Entergy Arkansas’s calculation of its weighted average cost of capital providing a return on the unamortized balance for the benefit of customers. Further, Entergy Arkansas proposes to flow the benefits of the solar production tax credits to customers through Entergy Arkansas’s formula rate plan, effective with the formula rate plan rates that will go into effect January 1, 2027. Entergy Arkansas’s proposal would result in the benefits of the production tax credits being passed through to customers, if approved, as reductions in revenue requirement evenly over the life of the assets, rather than only during the 10-year period in which the production tax credits are generated. In April 2026 the APSC general staff filed testimony proposing an amortization period of no more than 15 years for the monetized proceeds for the tax credits associated with the West Memphis Solar and Driver Solar facilities. An evidentiary hearing was held in July 2026, but was not completed. The APSC is to set a date to complete the hearing. Special Rate Contract and Arkansas Cypress Solar As discussed in the Form 10-K, in September 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of the Arkansas Cypress Solar facility, a planned 600 MW solar photovoltaic array with a 350 MW battery energy storage system and associated transmission facilities interconnecting at Entergy Arkansas’s White Bluff substation. The estimated cost of the project is $1,602 million. In March 2026 the APSC approved the Arkansas Cypress Solar facility and Entergy Arkansas’s recovery of the costs of the facility through the Generating Arkansas Jobs Act rider. The APSC also ordered implementation of an independent monitor to oversee costs. In April 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of costs. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including the Arkansas Cypress Solar facility, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates. No alternative recommendations were made by the other parties. The facility is expected to be in service by the end of 2028. Filings with the LPSC (Entergy Louisiana) Retail Rates Resilience Plan Cost Recovery Rider In December 2022, Entergy Louisiana filed an application with the LPSC seeking a public interest finding regarding Phase I of Entergy Louisiana’s Future Ready resilience plan and approval of a rider mechanism to recover the program’s costs. Phase I in the December 2022 application reflected the first five years of a ten-year resilience plan and included investment of approximately $5 billion, including hardening investment, transmission dead-end structures, enhanced vegetation management, and telecommunications improvement. In April 2024 the LPSC approved a framework which includes an initial five-year resilience plan providing for an investment of approximately $1.9 billion with cost recovery via a forward-looking rider with semi-annual true-ups. The plan is subject to specified reporting requirements and includes a performance review of the hardened assets. The LPSC order approving the framework does not include any restrictions on Entergy Louisiana’s ability to file applications for approval of additional investments in resilience. In January 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $40.4 million, or $38.9 million in incremental annual revenues from Entergy Louisiana’s first semi-annual filing in July 2024, for projects expected to be placed in service during the rate-effective period of March 2025 through August 2025. In February 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $50.2 million, or $9.8 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2025 through February 2026. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $5.6 million to be implemented in the January 2026 semi-annual filing. In August 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In January 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $101.8 million, or $51.6 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of March 2026 through August 2026. Additionally, Entergy Louisiana’s true-up filing included an over-recovery totaling $16.6 million to be implemented in the July 2026 semi-annual filing. In February 2026 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $114.2 million, or $12.4 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2026 through February 2027. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $2.5 million to be implemented in the January 2027 semi-annual filing. The LPSC staff is reviewing the filed rider rates. Vegetation Management Rider In November 2025 the LPSC staff issued notice of its initiation of a rulemaking to implement a vegetation management pilot program for LPSC jurisdictional electric utilities. The pilot program would be voluntary and would allow utilities to establish a rider for distribution vegetation management for up to 100% of the utility’s prior calendar year vegetation management spending. The rider may not exceed 1% of a customer’s bill, and the utility would be required to maintain its prior calendar year level of spending on vegetation management as reflected in its base rates or formula rate plan. In February 2026 the LPSC staff filed a report and recommendation along with a proposed final rule providing for the adoption of the pilot program consistent with the terms outlined in the original notice. In March 2026 the LPSC voted to accept the LPSC staff’s recommendation and adopt the proposed pilot program as presented. In April 2026, Entergy Louisiana filed its vegetation management rider for the rate-effective period of May 2026 through December 2026, which included a revenue requirement of $20 million for incremental spending on distribution vegetation management above the prior calendar year level of spending on vegetation management. 2025 Formula Rate Plan Filing In June 2026, Entergy Louisiana filed its formula rate plan evaluation report for its 2025 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 2025, the formula produced an earned return on equity of 9.63%, which falls within the established bandwidth and therefore results in no adjustment to base rider formula rate plan revenue. Additional changes in formula rate plan revenue include: (1) the removal of approximately $73 million in annual customer credits associated with the global stipulated settlement agreement, which have been fully credited to customers in accordance with the agreement; (2) a reduction in customer credits through the tax adjustment mechanism, attributable to the return of Entergy Louisiana’s over-collection of income tax expense associated with Louisiana state tax law changes effective in 2025 and the expiration of certain ad valorem exemptions; (3) increases in transmission and distribution plant in service, as recognized through the transmission and distribution recovery mechanisms, including restoration costs from Winter Storm Fern, for which Entergy Louisiana does not intend to seek relief or exception to the formula rate plan; (4) increases to the additional capacity mechanism; and (5) the final phase-in of additional nuclear depreciation expense, in accordance with the global stipulated settlement agreement. See Note 2 to the financial statements in the Form 10-K for discussion of the global stipulated settlement agreement. Collectively, these factors contributed to a net increase of $222 million in formula rate plan revenue for the period. Subject to LPSC review, the resulting changes from the 2025 formula rate plan evaluation report will become effective for bills rendered during the first billing cycle of September 2026, subject to refund. Request for Extension of Formula Rate Plan In June 2026, Entergy Louisiana submitted a motion requesting the LPSC approve a one-year extension of its current formula rate plan, with all material provisions left unchanged, including the allowed return on common equity of 9.7% with a bandwidth of 40 basis points above and below the midpoint. Entergy Louisiana has requested LPSC action on the proposed extension by August 2026. River Bend Deregulated Asset Plan Filing In September 2025, Entergy Louisiana filed an application seeking LPSC approval to recover from customers, prospectively, approximately $49 million in annual revenues associated with the Louisiana retail deregulated portion of River Bend. Costs associated with the deregulated portion of River Bend have historically been excluded from retail ratemaking as a result of a 1988 LPSC decision. Instead, Entergy Louisiana has been allowed by the LPSC to either recover 4.6 cents per kWh for the power generated from that portion of the plant, or sell the power into the applicable market (subject to certain restrictions). The filing presents evidence that River Bend is a cost-effective and prudent source of needed baseload supply with value to Entergy Louisiana customers and seeks to recover the previously excluded costs, on a prospective basis. In March 2026 the LPSC staff and certain intervenors filed direct testimony recommending that the LPSC deny Entergy Louisiana’s application. The LPSC staff’s testimony further recommends that, if the LPSC were to grant any relief, notwithstanding the LPSC staff’s recommendation, such relief should be limited to allowing only prospective capital additions at River Bend to be included in Entergy Louisiana’s customer rates. Entergy Louisiana’s rebuttal testimony is due in August 2026. A hearing is scheduled for January 2027. Filings with the MPSC (Entergy Mississippi) Retail Rates 2026 Formula Rate Plan Filing In February 2026, Entergy Mississippi submitted its formula rate plan 2026 test year filing and 2025 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2025 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2026 calendar year to also be within the formula rate plan bandwidth. The 2026 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2025 look-back filing compared actual 2025 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 $293 thousand to reflect one outside-the-bandwidth change, a true-up of demand side management costs. In June 2026, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2026 test year filing, with the exception of immaterial adjustments to certain operations and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2026, resulting in no change in formula rate plan revenues for 2026. Pursuant to the stipulation, Entergy Mississippi’s 2025 look-back filing reflected an earned return on rate base of 8.10%, which also resulted in no change in formula rate plan revenues for 2025. In addition, the stipulation included the recovery of the outside-the-bandwidth change discussed above as well as the ratemaking treatment of certain customer contributions, the mechanism for recovery of the benefits of nuclear production tax credits, and the realignment of the first project from the interim facilities rate adjustment to the formula rate plan. In June 2026 the MPSC approved the joint stipulation with rates effective in July 2026. See Note 10 to the financial statements herein for further discussion of the mechanism for recovery of the benefits of nuclear production tax credits included in the joint stipulation. Filings with the City Council (Entergy New Orleans) Retail Rates 2026 Formula Rate Plan Filing In April 2026, Entergy New Orleans submitted to the City Council its formula rate plan 2025 test year filing. The 2025 evaluation report produced an earned return on equity of 7.55% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in an increase in rates of $16.6 million. The increase in rates is driven, in part, by an increase in plant in service, as well as the cost of known and measurable capital additions. The increase is also driven by a decrease in total revenues due to a decline in kWh sales. The filing is subject to a 75-day review and discovery period followed by a 25-day period to resolve any disputes among the parties. In July 2026 the City Council’s advisors issued a report seeking a reduction in Entergy New Orleans’s requested formula rate plan revenues of approximately $4.4 million due to certain proposed cost realignments, imputation of revenues, and disallowances. The City Council’s advisors also recommended that Entergy New Orleans be permitted to collect $20 million over five years beginning in September 2026 to recover amounts that it might be required to pay Entergy Louisiana and Entergy Arkansas pursuant to a FERC order issued in June 2026, relating to an alleged MSS-4 replacement tariff (MSS-4R) violation. However, the FERC order is unclear on its face, and the specific amount of a payment, if any, is unknown. Requests for rehearing and clarification of the FERC order are pending. See “MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding” below for additional discussion of the FERC order. If any rate adjustments are not resolved, the City Council would set a procedural schedule to resolve such disputes. A response by Entergy New Orleans to the advisors’ report is due in August 2026. Resulting rates will be effective with the first billing cycle of September 2026 pursuant to the formula rate plan tariff. Request for Extension of Formula Rate Plan In July 2026, Entergy New Orleans submitted a motion requesting the City Council approve a four-year extension of its current formula rate plan, with all material provisions left unchanged, including the authorized return on equity of 9.35% with a bandwidth of 50 basis points above and below the midpoint. Entergy New Orleans has requested City Council action on the proposed extension by August 2026. Filings with the PUCT and Texas Cities (Entergy Texas) Retail Rates Distribution Cost Recovery Factor (DCRF) Rider In April 2026, 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 $112.5 million annually, or $20.4 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2025 and December 31, 2025. In July 2026 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after July 8, 2026. Transmission Cost Recovery Factor (TCRF) Rider As discussed in the Form 10-K, in October 2025, Entergy Texas filed with the PUCT a request to amend its TCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $30.3 million annually, or $20.6 million in incremental annual revenues beyond Entergy Texas’s then-effective TCRF rider based on its capital invested in transmission between July 1, 2024 and June 30, 2025 and changes in other transmission charges. In April 2026 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 6, 2026. Generation Cost Recovery Rider In March 2026, Entergy Texas filed an application to establish a generation cost recovery rider to begin recovering a return of and on its capital investment in the Orange County Advanced Power Station. The proposed generation cost recovery rider, which includes Entergy Texas’s capital invested in generation for the Orange County Advanced Power Station through December 31, 2025, is designed to collect approximately $150.4 million annually from Entergy Texas’s retail customers. By statute, the proposed generation cost recovery rider rates are to become effective when the Orange County Advanced Power Station is placed into service, which is expected in third quarter 2026. In July 2026 the ALJ with the State Office of Administrative Hearings approved a proposed procedural schedule that includes a hearing on the merits in September 2026 and provides for interim rates to become effective for usage on and after the Orange County Advanced Power Station in-service date, to the extent final rates are not in place by that time. Capacity Cost Recovery Rider (CCRR) In May 2026, Entergy Texas filed with the PUCT a request to establish a new CCRR. The proposed CCRR is designed to collect approximately $58 million annually from Entergy Texas’s retail customers based on Entergy Texas’s eligible capacity-related costs and revenues for the 12 months beginning June 1, 2026. The eligible capacity-related costs and revenues are associated with Entergy Texas’s participation in MISO’s annual planning resource auction. In July 2026 the PUCT approved the CCRR, consistent with Entergy Texas’s as-filed request, and rates became effective on July 10, 2026. Entergy Arkansas Opportunity Sales Proceeding See Note 2 to the financial statements in the Form 10-K for discussion of the Entergy Arkansas opportunity sales proceeding. Complaints Against System Energy See Note 2 to the financial statements in the Form 10-K for information regarding complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. Unit Power Sales Agreement See Note 2 to the financial statements in the Form 10-K for discussion of the Unit Power Sales Agreement. The following is an update to that discussion. Pension Costs Amendment Proceeding As discussed in the Form 10-K, in October 2021, System Energy submitted to the FERC proposed amendments to the Unit Power Sales Agreement to include in rate base the prepaid and accrued pension costs associated with System Energy’s qualified pension plans. In November 2025 the FERC issued an order approving System Energy’s proposed prepaid and accrued pension recovery mechanism. System Energy has been utilizing this methodology in billings since December 1, 2022 and will continue to utilize it going forward. As a result of the FERC’s order, System Energy did not owe any refunds. In December 2025 the APSC filed a request for rehearing of the November 2025 order. In January 2026 the FERC denied the APSC’s rehearing request by operation of law. In May 2026 the FERC issued a follow-up substantive order denying the APSC’s rehearing and sustaining its finding that no refunds are owed. 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-4R net operating loss carryforward proceeding. The following is an update to that discussion. As discussed in the Form 10-K, in October 2021 the LPSC filed a complaint with the FERC alleging that Entergy Services improperly excluded net operating loss carryforward accumulated deferred income taxes (NOLC ADIT) from MSS-4R rates in the period before March 20, 2021. The LPSC argued that sales from Entergy Louisiana to Entergy Texas and Entergy New Orleans were charged at rates lower than they otherwise should have been, and it accordingly seeks surcharges for the period prior to March 20, 2021. The FERC set the complaint for hearing procedures and subsequently the hearing for this complaint proceeding was consolidated with the hearing procedures for Entergy Services’ January 2021 NOLC ADIT filing. Testimony was filed by parties in 2023, and the hearing before a FERC ALJ was concluded in February 2024. In June 2024, the FERC ALJ issued an initial decision addressing three major issues: (1) whether Entergy Services’ proposed prospective inclusion and allocation of NOLC ADIT in MSS-4R rates using a modified with-and-without methodology is just and reasonable; (2) whether Entergy Services correctly calculated excess and deficient accumulated deferred income taxes in accordance with the terms of a prior settlement; and (3) whether NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the January 2021 MSS-4R filing. With respect to issues (1) and (2), the presiding ALJ concluded that Entergy Services’ proposed methodology for allocating and including NOLC ADIT in MSS-4R rates was just and reasonable and that Entergy Services correctly performed the excess and deficient accumulated deferred income taxes calculations. With respect to issue (3), however, the presiding ALJ agreed with the LPSC that NOLC ADIT should have been included in MSS-4R rates since September 1, 2016, and as a result, the presiding ALJ ordered that Entergy Louisiana and Entergy Arkansas recalculate bills for the period of September 1, 2016 through November 11, 2023 with surcharges expected to be due to those operating companies from the purchasing operating companies, Entergy New Orleans, Entergy Texas, and Entergy Louisiana (for some Entergy Arkansas sales). The presiding ALJ also ordered Entergy Services to pay the interest owed to Entergy Louisiana on these surcharges. The surcharge methodology that the presiding ALJ recommended in connection with issue (3) was not supported by any participant in the hearing. As part of their exceptions to the initial decision, all parties to the proceeding opposed the use of the ALJ’s methodology, except for the FERC trial staff, which took no position. During the hearing, the LPSC and the FERC trial staff advocated that the alleged tariff violation should be remedied by the application of Entergy Services’ January 2021 proposed methodology. All other parties, including the PUCT, the City Council, and Entergy Services, opposed any surcharges for the period prior to the March 20, 2021 effective date of the January 2021 filing. Entergy Services disputed the presiding ALJ's rulings on issue (3) and filed exceptions to these rulings in July 2024. In June 2026 the FERC issued its opinion largely affirming the initial decision. Specifically, the FERC found the historic exclusion of NOLC ADIT from MSS-4R rates was a tariff violation and ordered Entergy Louisiana and Entergy Arkansas to provide refunds and/or surcharges, as appropriate, for the period from September 1, 2016 through November 12, 2023 for sales by Entergy Louisiana and for the period December 19, 2013 until May 13, 2024 for sales by Entergy Arkansas. The FERC also ordered the relevant operating company to pay interest on the amounts owed. In July 2026, Entergy Services, along with the LPSC, the City Council, and the PUCT, filed for rehearing and clarification of the FERC’s order. Entergy Services continues to dispute that the NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the tariff amendment filing. Moreover, because of ambiguity in the order and the pending rehearing and clarification requests, it is unclear whether Entergy Arkansas and Entergy Louisiana as sellers will receive surcharges or have to provide refunds. Specifically, there is a lack of clarity as to whether plant-related liability accumulated deferred income taxes must be included in calculating refunds/surcharges. Entergy Services also identified a lack of clarity regarding including the nuclear decommissioning liability deduction in the NOLC ADIT calculation. Depending on the guidance issued by the FERC in response to the request for rehearing and clarification of its June 2026 order, each of the affected Entergy operating companies could either receive material refunds or owe material surcharges. As such, any amounts payable or receivable between the Entergy operating companies that may result from the order are not reasonably estimable as of June 30, 2026. MSS-4 Replacement Tariff – River Bend 70 Depreciation LPSC Complaint In May 2026 the LPSC filed a complaint with the FERC alleging that Entergy Texas owes surcharges to Entergy Louisiana because the depreciation rates used in the MSS-4R for the River Bend 70 sales of capacity and energy were based on a directive of the PUCT for the period from September 1, 2016 to December 31, 2025. The LPSC quantifies the potential surcharge as $100 million, inclusive of interest. Entergy Services disputes that any surcharges are due from Entergy Texas to Entergy Louisiana. In June 2026, Entergy Services filed a motion to dismiss and answer to the complaint submitted by the LPSC. Joint Targeted Interconnection Queue Cost Allocation Dispute In April 2026, MISO submitted to the FERC an unexecuted agreement proposing to assign to Entergy Texas (in its capacity as the owner of the Legend Power Station) costs associated with the MISO and Southwest Power Pool Joint Targeted Interconnection Queue. Entergy Texas estimates that MISO’s proposed cost assignment would result in total charges of approximately $112 million, paid over twenty years beginning in 2031. In May 2026, Entergy Texas filed a protest to the agreement, as well as a separate complaint at the FERC, arguing that the proposed cost allocation is not just and reasonable. In June 2026 the FERC issued a deficiency notice to MISO. In July 2026, MISO and Southwest Power Pool filed answers to the complaint, and MISO filed an answer to the deficiency letter. Protests and comments in response to MISO’s answer to the deficiency letter are due in August 2026.

Public Utilities Disclosure [Text Block]	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 2026, 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 $0.01333 per kWh to $0.01508 per kWh. The primary reason for the rate increase was an under-recovered balance as a result of higher natural gas prices in 2025. Based on circumstances related to ANO 2’s refueling outage, Entergy Arkansas made an adjustment to projected energy costs to phase-in the rate increase gradually. The redetermined rate of $0.01508 per kWh became effective with the first billing cycle in April 2026 through the normal operation of the tariff. Entergy Louisiana As discussed in the Form 10-K, in June 2025 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings (for Entergy Louisiana’s gas operations). The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from January 2023 through June 2025. The LPSC staff issued its audit report in March 2026. The next step is for the LPSC to issue its final report, but there is no deadline or timing requirement associated with the issuance of the final report. In February 2026, Entergy Louisiana, in its monthly filing to update its fuel adjustment clause, requested to defer approximately $141.9 million of fuel costs incurred in January 2026 that were primarily attributable to the effects of Winter Storm Fern, consistent with the LPSC’s general order approved at its February 2026 meeting permitting temporary modifications to the LPSC’s fuel adjustment clause general order. The filing proposed to defer the recovery of these fuel costs over a four-month period from March 2026 through June 2026 to mitigate the customer bill impacts of these fuel costs. In March 2026 the LPSC issued a special order delegating authority to the LPSC executive secretary to review and approve utility-specific requests for deferral of fuel costs from Winter Storm Fern, subject to audit as per the LPSC’s fuel clause general order. In April 2026 the LPSC executive secretary approved Entergy Louisiana’s request for deferral. In April 2026 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2023 through 2025. Discovery is ongoing, and no audit report has been filed. 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 2026 Base Rate Case In February 2026, Entergy Arkansas filed with the APSC a general change in rates, charges, and tariffs. The filing requested a base rate increase to recover a base rate revenue deficiency of $44.6 million and notified the APSC of Entergy Arkansas’s intent to implement a forward test year formula rate plan pursuant to Arkansas legislation passed in 2015. The primary drivers of the revenue deficiency were increased depreciation expense and the impact of net capital additions. Additionally, the filing requested a 9.90% return on common equity and increased depreciation rates as the result of a depreciation study. In March 2026 the APSC issued an order suspending the proposed rates and tariffs filed by Entergy Arkansas. In June 2026 the APSC established a procedural schedule with an evidentiary hearing scheduled to begin in November 2026, and in July 2026 a number of intervenors moved to modify the schedule to conduct additional discovery. Entergy Arkansas opposed the motion in part based on the voluminous discovery conducted to date. 2026 Formula Rate Plan Filing In July 2026, Entergy Arkansas filed with the APSC its 2026 formula rate plan filing to set its formula rate for the 2027 calendar year. The filing contained an evaluation of Entergy Arkansas’s earnings and a netting adjustment for the 2025 historical year. The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2025 historical year was 8.8%, resulting in a $47.2 million formula rate plan revenue increase to produce a 9.65% earned rate of return on common equity. When combined with 2025 historical year formula rate plan revenues of $56.0 million, the total proposed revenue change for the 2025 historical year netting adjustment is a reduction of $8.8 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. Entergy Arkansas’s revenue requirement in this filing did not exceed the constraint. In second quarter 2026, Entergy Arkansas recorded a regulatory liability of $8.8 million to reflect the amount of the 2025 historical year netting adjustment that it collected from customers during the 2025 rate effective period. Generating Arkansas Jobs Act Rider In March 2026, Entergy Arkansas filed its first annual update to the strategic investment recovery rider, requesting recovery of $110.4 million of financing costs during construction of generation and transmission strategic investments related to Ironwood Power Station, Jefferson Power Station, and the Arkansas Cypress Solar facility. The revised rates were requested to be effective with the first billing cycle of June 2026. In April 2026 the APSC general staff filed testimony arguing that the APSC had not issued an order designating Ironwood Power Station as a strategic investment and that related costs should therefore be removed from the annual update. Also in April 2026, Entergy Arkansas filed testimony asserting that the APSC general staff’s position is contrary to the plain language of the statute, which includes an exception for facilities like Ironwood Power Station that were certified by the APSC within a certain timeframe. A hearing was held in April 2026. In June 2026 the APSC approved Entergy Arkansas’s annual update, and rates became effective June 4, 2026. Production Tax Credit Tariffs As discussed in Note 3 to the financial statements in the Form 10-K, in January 2026 the APSC opened a docket to investigate the sale of Entergy Arkansas’s nuclear production tax credits and the appropriate ratemaking treatment of production tax credits for all of Entergy Arkansas’s eligible resources, including how the proceeds of any sales should flow through to customers. For nuclear production tax credits, Entergy Arkansas proposed a nuclear production tax credit rider, which would provide for the immediate flow through to customers of the weighted average cost of capital return on the net proceeds of the monetized nuclear production tax credits. Recognizing that the timing and determination from the IRS is uncertain, the nuclear production tax credit rider also proposes that, if there is an unfavorable IRS determination, Entergy Arkansas would collect applicable costs from customers. As directed by the APSC, in February 2026, Entergy Arkansas submitted a compliance filing to the APSC verifying the status of the solar production tax credits. The filing also verified that the net proceeds from the sale of the nuclear production tax credits were recorded in FERC accounts that are accruing a return for customers’ benefit at a rate that is above the customer deposit rate. Subsequently, in March 2026, Entergy Arkansas filed testimony setting forth its proposal for the solar production tax credits. Specifically, Entergy Arkansas requested the same ratemaking treatment for all of the solar facilities that the APSC already approved for Walnut Bend (i.e., the total net monetized proceeds from production tax credits expected to be generated over the first ten years of a solar facility’s operation are estimated and then amortized over the expected useful life of the asset, which is typically 30 years). Additionally, consistent with prior orders for these resources, the regulatory liabilities associated with the net cash proceeds from monetized solar production tax credits will be included in Entergy Arkansas’s calculation of its weighted average cost of capital providing a return on the unamortized balance for the benefit of customers. Further, Entergy Arkansas proposes to flow the benefits of the solar production tax credits to customers through Entergy Arkansas’s formula rate plan, effective with the formula rate plan rates that will go into effect January 1, 2027. Entergy Arkansas’s proposal would result in the benefits of the production tax credits being passed through to customers, if approved, as reductions in revenue requirement evenly over the life of the assets, rather than only during the 10-year period in which the production tax credits are generated. In April 2026 the APSC general staff filed testimony proposing an amortization period of no more than 15 years for the monetized proceeds for the tax credits associated with the West Memphis Solar and Driver Solar facilities. An evidentiary hearing was held in July 2026, but was not completed. The APSC is to set a date to complete the hearing. Special Rate Contract and Arkansas Cypress Solar As discussed in the Form 10-K, in September 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of the Arkansas Cypress Solar facility, a planned 600 MW solar photovoltaic array with a 350 MW battery energy storage system and associated transmission facilities interconnecting at Entergy Arkansas’s White Bluff substation. The estimated cost of the project is $1,602 million. In March 2026 the APSC approved the Arkansas Cypress Solar facility and Entergy Arkansas’s recovery of the costs of the facility through the Generating Arkansas Jobs Act rider. The APSC also ordered implementation of an independent monitor to oversee costs. In April 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of costs. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including the Arkansas Cypress Solar facility, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates. No alternative recommendations were made by the other parties. The facility is expected to be in service by the end of 2028. Filings with the LPSC (Entergy Louisiana) Retail Rates Resilience Plan Cost Recovery Rider In December 2022, Entergy Louisiana filed an application with the LPSC seeking a public interest finding regarding Phase I of Entergy Louisiana’s Future Ready resilience plan and approval of a rider mechanism to recover the program’s costs. Phase I in the December 2022 application reflected the first five years of a ten-year resilience plan and included investment of approximately $5 billion, including hardening investment, transmission dead-end structures, enhanced vegetation management, and telecommunications improvement. In April 2024 the LPSC approved a framework which includes an initial five-year resilience plan providing for an investment of approximately $1.9 billion with cost recovery via a forward-looking rider with semi-annual true-ups. The plan is subject to specified reporting requirements and includes a performance review of the hardened assets. The LPSC order approving the framework does not include any restrictions on Entergy Louisiana’s ability to file applications for approval of additional investments in resilience. In January 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $40.4 million, or $38.9 million in incremental annual revenues from Entergy Louisiana’s first semi-annual filing in July 2024, for projects expected to be placed in service during the rate-effective period of March 2025 through August 2025. In February 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $50.2 million, or $9.8 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2025 through February 2026. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $5.6 million to be implemented in the January 2026 semi-annual filing. In August 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In January 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $101.8 million, or $51.6 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of March 2026 through August 2026. Additionally, Entergy Louisiana’s true-up filing included an over-recovery totaling $16.6 million to be implemented in the July 2026 semi-annual filing. In February 2026 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $114.2 million, or $12.4 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2026 through February 2027. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $2.5 million to be implemented in the January 2027 semi-annual filing. The LPSC staff is reviewing the filed rider rates. Vegetation Management Rider In November 2025 the LPSC staff issued notice of its initiation of a rulemaking to implement a vegetation management pilot program for LPSC jurisdictional electric utilities. The pilot program would be voluntary and would allow utilities to establish a rider for distribution vegetation management for up to 100% of the utility’s prior calendar year vegetation management spending. The rider may not exceed 1% of a customer’s bill, and the utility would be required to maintain its prior calendar year level of spending on vegetation management as reflected in its base rates or formula rate plan. In February 2026 the LPSC staff filed a report and recommendation along with a proposed final rule providing for the adoption of the pilot program consistent with the terms outlined in the original notice. In March 2026 the LPSC voted to accept the LPSC staff’s recommendation and adopt the proposed pilot program as presented. In April 2026, Entergy Louisiana filed its vegetation management rider for the rate-effective period of May 2026 through December 2026, which included a revenue requirement of $20 million for incremental spending on distribution vegetation management above the prior calendar year level of spending on vegetation management. 2025 Formula Rate Plan Filing In June 2026, Entergy Louisiana filed its formula rate plan evaluation report for its 2025 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 2025, the formula produced an earned return on equity of 9.63%, which falls within the established bandwidth and therefore results in no adjustment to base rider formula rate plan revenue. Additional changes in formula rate plan revenue include: (1) the removal of approximately $73 million in annual customer credits associated with the global stipulated settlement agreement, which have been fully credited to customers in accordance with the agreement; (2) a reduction in customer credits through the tax adjustment mechanism, attributable to the return of Entergy Louisiana’s over-collection of income tax expense associated with Louisiana state tax law changes effective in 2025 and the expiration of certain ad valorem exemptions; (3) increases in transmission and distribution plant in service, as recognized through the transmission and distribution recovery mechanisms, including restoration costs from Winter Storm Fern, for which Entergy Louisiana does not intend to seek relief or exception to the formula rate plan; (4) increases to the additional capacity mechanism; and (5) the final phase-in of additional nuclear depreciation expense, in accordance with the global stipulated settlement agreement. See Note 2 to the financial statements in the Form 10-K for discussion of the global stipulated settlement agreement. Collectively, these factors contributed to a net increase of $222 million in formula rate plan revenue for the period. Subject to LPSC review, the resulting changes from the 2025 formula rate plan evaluation report will become effective for bills rendered during the first billing cycle of September 2026, subject to refund. Request for Extension of Formula Rate Plan In June 2026, Entergy Louisiana submitted a motion requesting the LPSC approve a one-year extension of its current formula rate plan, with all material provisions left unchanged, including the allowed return on common equity of 9.7% with a bandwidth of 40 basis points above and below the midpoint. Entergy Louisiana has requested LPSC action on the proposed extension by August 2026. River Bend Deregulated Asset Plan Filing In September 2025, Entergy Louisiana filed an application seeking LPSC approval to recover from customers, prospectively, approximately $49 million in annual revenues associated with the Louisiana retail deregulated portion of River Bend. Costs associated with the deregulated portion of River Bend have historically been excluded from retail ratemaking as a result of a 1988 LPSC decision. Instead, Entergy Louisiana has been allowed by the LPSC to either recover 4.6 cents per kWh for the power generated from that portion of the plant, or sell the power into the applicable market (subject to certain restrictions). The filing presents evidence that River Bend is a cost-effective and prudent source of needed baseload supply with value to Entergy Louisiana customers and seeks to recover the previously excluded costs, on a prospective basis. In March 2026 the LPSC staff and certain intervenors filed direct testimony recommending that the LPSC deny Entergy Louisiana’s application. The LPSC staff’s testimony further recommends that, if the LPSC were to grant any relief, notwithstanding the LPSC staff’s recommendation, such relief should be limited to allowing only prospective capital additions at River Bend to be included in Entergy Louisiana’s customer rates. Entergy Louisiana’s rebuttal testimony is due in August 2026. A hearing is scheduled for January 2027. Filings with the MPSC (Entergy Mississippi) Retail Rates 2026 Formula Rate Plan Filing In February 2026, Entergy Mississippi submitted its formula rate plan 2026 test year filing and 2025 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2025 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2026 calendar year to also be within the formula rate plan bandwidth. The 2026 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2025 look-back filing compared actual 2025 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 $293 thousand to reflect one outside-the-bandwidth change, a true-up of demand side management costs. In June 2026, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2026 test year filing, with the exception of immaterial adjustments to certain operations and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2026, resulting in no change in formula rate plan revenues for 2026. Pursuant to the stipulation, Entergy Mississippi’s 2025 look-back filing reflected an earned return on rate base of 8.10%, which also resulted in no change in formula rate plan revenues for 2025. In addition, the stipulation included the recovery of the outside-the-bandwidth change discussed above as well as the ratemaking treatment of certain customer contributions, the mechanism for recovery of the benefits of nuclear production tax credits, and the realignment of the first project from the interim facilities rate adjustment to the formula rate plan. In June 2026 the MPSC approved the joint stipulation with rates effective in July 2026. See Note 10 to the financial statements herein for further discussion of the mechanism for recovery of the benefits of nuclear production tax credits included in the joint stipulation. Filings with the City Council (Entergy New Orleans) Retail Rates 2026 Formula Rate Plan Filing In April 2026, Entergy New Orleans submitted to the City Council its formula rate plan 2025 test year filing. The 2025 evaluation report produced an earned return on equity of 7.55% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in an increase in rates of $16.6 million. The increase in rates is driven, in part, by an increase in plant in service, as well as the cost of known and measurable capital additions. The increase is also driven by a decrease in total revenues due to a decline in kWh sales. The filing is subject to a 75-day review and discovery period followed by a 25-day period to resolve any disputes among the parties. In July 2026 the City Council’s advisors issued a report seeking a reduction in Entergy New Orleans’s requested formula rate plan revenues of approximately $4.4 million due to certain proposed cost realignments, imputation of revenues, and disallowances. The City Council’s advisors also recommended that Entergy New Orleans be permitted to collect $20 million over five years beginning in September 2026 to recover amounts that it might be required to pay Entergy Louisiana and Entergy Arkansas pursuant to a FERC order issued in June 2026, relating to an alleged MSS-4 replacement tariff (MSS-4R) violation. However, the FERC order is unclear on its face, and the specific amount of a payment, if any, is unknown. Requests for rehearing and clarification of the FERC order are pending. See “MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding” below for additional discussion of the FERC order. If any rate adjustments are not resolved, the City Council would set a procedural schedule to resolve such disputes. A response by Entergy New Orleans to the advisors’ report is due in August 2026. Resulting rates will be effective with the first billing cycle of September 2026 pursuant to the formula rate plan tariff. Request for Extension of Formula Rate Plan In July 2026, Entergy New Orleans submitted a motion requesting the City Council approve a four-year extension of its current formula rate plan, with all material provisions left unchanged, including the authorized return on equity of 9.35% with a bandwidth of 50 basis points above and below the midpoint. Entergy New Orleans has requested City Council action on the proposed extension by August 2026. Filings with the PUCT and Texas Cities (Entergy Texas) Retail Rates Distribution Cost Recovery Factor (DCRF) Rider In April 2026, 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 $112.5 million annually, or $20.4 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2025 and December 31, 2025. In July 2026 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after July 8, 2026. Transmission Cost Recovery Factor (TCRF) Rider As discussed in the Form 10-K, in October 2025, Entergy Texas filed with the PUCT a request to amend its TCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $30.3 million annually, or $20.6 million in incremental annual revenues beyond Entergy Texas’s then-effective TCRF rider based on its capital invested in transmission between July 1, 2024 and June 30, 2025 and changes in other transmission charges. In April 2026 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 6, 2026. Generation Cost Recovery Rider In March 2026, Entergy Texas filed an application to establish a generation cost recovery rider to begin recovering a return of and on its capital investment in the Orange County Advanced Power Station. The proposed generation cost recovery rider, which includes Entergy Texas’s capital invested in generation for the Orange County Advanced Power Station through December 31, 2025, is designed to collect approximately $150.4 million annually from Entergy Texas’s retail customers. By statute, the proposed generation cost recovery rider rates are to become effective when the Orange County Advanced Power Station is placed into service, which is expected in third quarter 2026. In July 2026 the ALJ with the State Office of Administrative Hearings approved a proposed procedural schedule that includes a hearing on the merits in September 2026 and provides for interim rates to become effective for usage on and after the Orange County Advanced Power Station in-service date, to the extent final rates are not in place by that time. Capacity Cost Recovery Rider (CCRR) In May 2026, Entergy Texas filed with the PUCT a request to establish a new CCRR. The proposed CCRR is designed to collect approximately $58 million annually from Entergy Texas’s retail customers based on Entergy Texas’s eligible capacity-related costs and revenues for the 12 months beginning June 1, 2026. The eligible capacity-related costs and revenues are associated with Entergy Texas’s participation in MISO’s annual planning resource auction. In July 2026 the PUCT approved the CCRR, consistent with Entergy Texas’s as-filed request, and rates became effective on July 10, 2026. Entergy Arkansas Opportunity Sales Proceeding See Note 2 to the financial statements in the Form 10-K for discussion of the Entergy Arkansas opportunity sales proceeding. Complaints Against System Energy See Note 2 to the financial statements in the Form 10-K for information regarding complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. Unit Power Sales Agreement See Note 2 to the financial statements in the Form 10-K for discussion of the Unit Power Sales Agreement. The following is an update to that discussion. Pension Costs Amendment Proceeding As discussed in the Form 10-K, in October 2021, System Energy submitted to the FERC proposed amendments to the Unit Power Sales Agreement to include in rate base the prepaid and accrued pension costs associated with System Energy’s qualified pension plans. In November 2025 the FERC issued an order approving System Energy’s proposed prepaid and accrued pension recovery mechanism. System Energy has been utilizing this methodology in billings since December 1, 2022 and will continue to utilize it going forward. As a result of the FERC’s order, System Energy did not owe any refunds. In December 2025 the APSC filed a request for rehearing of the November 2025 order. In January 2026 the FERC denied the APSC’s rehearing request by operation of law. In May 2026 the FERC issued a follow-up substantive order denying the APSC’s rehearing and sustaining its finding that no refunds are owed. 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-4R net operating loss carryforward proceeding. The following is an update to that discussion. As discussed in the Form 10-K, in October 2021 the LPSC filed a complaint with the FERC alleging that Entergy Services improperly excluded net operating loss carryforward accumulated deferred income taxes (NOLC ADIT) from MSS-4R rates in the period before March 20, 2021. The LPSC argued that sales from Entergy Louisiana to Entergy Texas and Entergy New Orleans were charged at rates lower than they otherwise should have been, and it accordingly seeks surcharges for the period prior to March 20, 2021. The FERC set the complaint for hearing procedures and subsequently the hearing for this complaint proceeding was consolidated with the hearing procedures for Entergy Services’ January 2021 NOLC ADIT filing. Testimony was filed by parties in 2023, and the hearing before a FERC ALJ was concluded in February 2024. In June 2024, the FERC ALJ issued an initial decision addressing three major issues: (1) whether Entergy Services’ proposed prospective inclusion and allocation of NOLC ADIT in MSS-4R rates using a modified with-and-without methodology is just and reasonable; (2) whether Entergy Services correctly calculated excess and deficient accumulated deferred income taxes in accordance with the terms of a prior settlement; and (3) whether NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the January 2021 MSS-4R filing. With respect to issues (1) and (2), the presiding ALJ concluded that Entergy Services’ proposed methodology for allocating and including NOLC ADIT in MSS-4R rates was just and reasonable and that Entergy Services correctly performed the excess and deficient accumulated deferred income taxes calculations. With respect to issue (3), however, the presiding ALJ agreed with the LPSC that NOLC ADIT should have been included in MSS-4R rates since September 1, 2016, and as a result, the presiding ALJ ordered that Entergy Louisiana and Entergy Arkansas recalculate bills for the period of September 1, 2016 through November 11, 2023 with surcharges expected to be due to those operating companies from the purchasing operating companies, Entergy New Orleans, Entergy Texas, and Entergy Louisiana (for some Entergy Arkansas sales). The presiding ALJ also ordered Entergy Services to pay the interest owed to Entergy Louisiana on these surcharges. The surcharge methodology that the presiding ALJ recommended in connection with issue (3) was not supported by any participant in the hearing. As part of their exceptions to the initial decision, all parties to the proceeding opposed the use of the ALJ’s methodology, except for the FERC trial staff, which took no position. During the hearing, the LPSC and the FERC trial staff advocated that the alleged tariff violation should be remedied by the application of Entergy Services’ January 2021 proposed methodology. All other parties, including the PUCT, the City Council, and Entergy Services, opposed any surcharges for the period prior to the March 20, 2021 effective date of the January 2021 filing. Entergy Services disputed the presiding ALJ's rulings on issue (3) and filed exceptions to these rulings in July 2024. In June 2026 the FERC issued its opinion largely affirming the initial decision. Specifically, the FERC found the historic exclusion of NOLC ADIT from MSS-4R rates was a tariff violation and ordered Entergy Louisiana and Entergy Arkansas to provide refunds and/or surcharges, as appropriate, for the period from September 1, 2016 through November 12, 2023 for sales by Entergy Louisiana and for the period December 19, 2013 until May 13, 2024 for sales by Entergy Arkansas. The FERC also ordered the relevant operating company to pay interest on the amounts owed. In July 2026, Entergy Services, along with the LPSC, the City Council, and the PUCT, filed for rehearing and clarification of the FERC’s order. Entergy Services continues to dispute that the NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the tariff amendment filing. Moreover, because of ambiguity in the order and the pending rehearing and clarification requests, it is unclear whether Entergy Arkansas and Entergy Louisiana as sellers will receive surcharges or have to provide refunds. Specifically, there is a lack of clarity as to whether plant-related liability accumulated deferred income taxes must be included in calculating refunds/surcharges. Entergy Services also identified a lack of clarity regarding including the nuclear decommissioning liability deduction in the NOLC ADIT calculation. Depending on the guidance issued by the FERC in response to the request for rehearing and clarification of its June 2026 order, each of the affected Entergy operating companies could either receive material refunds or owe material surcharges. As such, any amounts payable or receivable between the Entergy operating companies that may result from the order are not reasonably estimable as of June 30, 2026. MSS-4 Replacement Tariff – River Bend 70 Depreciation LPSC Complaint In May 2026 the LPSC filed a complaint with the FERC alleging that Entergy Texas owes surcharges to Entergy Louisiana because the depreciation rates used in the MSS-4R for the River Bend 70 sales of capacity and energy were based on a directive of the PUCT for the period from September 1, 2016 to December 31, 2025. The LPSC quantifies the potential surcharge as $100 million, inclusive of interest. Entergy Services disputes that any surcharges are due from Entergy Texas to Entergy Louisiana. In June 2026, Entergy Services filed a motion to dismiss and answer to the complaint submitted by the LPSC. Joint Targeted Interconnection Queue Cost Allocation Dispute In April 2026, MISO submitted to the FERC an unexecuted agreement proposing to assign to Entergy Texas (in its capacity as the owner of the Legend Power Station) costs associated with the MISO and Southwest Power Pool Joint Targeted Interconnection Queue. Entergy Texas estimates that MISO’s proposed cost assignment would result in total charges of approximately $112 million, paid over twenty years beginning in 2031. In May 2026, Entergy Texas filed a protest to the agreement, as well as a separate complaint at the FERC, arguing that the proposed cost allocation is not just and reasonable. In June 2026 the FERC issued a deficiency notice to MISO. In July 2026, MISO and Southwest Power Pool filed answers to the complaint, and MISO filed an answer to the deficiency letter. Protests and comments in response to MISO’s answer to the deficiency letter are due in August 2026.

Public Utilities Disclosure [Text Block]	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 2026, 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 $0.01333 per kWh to $0.01508 per kWh. The primary reason for the rate increase was an under-recovered balance as a result of higher natural gas prices in 2025. Based on circumstances related to ANO 2’s refueling outage, Entergy Arkansas made an adjustment to projected energy costs to phase-in the rate increase gradually. The redetermined rate of $0.01508 per kWh became effective with the first billing cycle in April 2026 through the normal operation of the tariff. Entergy Louisiana As discussed in the Form 10-K, in June 2025 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings (for Entergy Louisiana’s gas operations). The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from January 2023 through June 2025. The LPSC staff issued its audit report in March 2026. The next step is for the LPSC to issue its final report, but there is no deadline or timing requirement associated with the issuance of the final report. In February 2026, Entergy Louisiana, in its monthly filing to update its fuel adjustment clause, requested to defer approximately $141.9 million of fuel costs incurred in January 2026 that were primarily attributable to the effects of Winter Storm Fern, consistent with the LPSC’s general order approved at its February 2026 meeting permitting temporary modifications to the LPSC’s fuel adjustment clause general order. The filing proposed to defer the recovery of these fuel costs over a four-month period from March 2026 through June 2026 to mitigate the customer bill impacts of these fuel costs. In March 2026 the LPSC issued a special order delegating authority to the LPSC executive secretary to review and approve utility-specific requests for deferral of fuel costs from Winter Storm Fern, subject to audit as per the LPSC’s fuel clause general order. In April 2026 the LPSC executive secretary approved Entergy Louisiana’s request for deferral. In April 2026 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2023 through 2025. Discovery is ongoing, and no audit report has been filed. 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 2026 Base Rate Case In February 2026, Entergy Arkansas filed with the APSC a general change in rates, charges, and tariffs. The filing requested a base rate increase to recover a base rate revenue deficiency of $44.6 million and notified the APSC of Entergy Arkansas’s intent to implement a forward test year formula rate plan pursuant to Arkansas legislation passed in 2015. The primary drivers of the revenue deficiency were increased depreciation expense and the impact of net capital additions. Additionally, the filing requested a 9.90% return on common equity and increased depreciation rates as the result of a depreciation study. In March 2026 the APSC issued an order suspending the proposed rates and tariffs filed by Entergy Arkansas. In June 2026 the APSC established a procedural schedule with an evidentiary hearing scheduled to begin in November 2026, and in July 2026 a number of intervenors moved to modify the schedule to conduct additional discovery. Entergy Arkansas opposed the motion in part based on the voluminous discovery conducted to date. 2026 Formula Rate Plan Filing In July 2026, Entergy Arkansas filed with the APSC its 2026 formula rate plan filing to set its formula rate for the 2027 calendar year. The filing contained an evaluation of Entergy Arkansas’s earnings and a netting adjustment for the 2025 historical year. The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2025 historical year was 8.8%, resulting in a $47.2 million formula rate plan revenue increase to produce a 9.65% earned rate of return on common equity. When combined with 2025 historical year formula rate plan revenues of $56.0 million, the total proposed revenue change for the 2025 historical year netting adjustment is a reduction of $8.8 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. Entergy Arkansas’s revenue requirement in this filing did not exceed the constraint. In second quarter 2026, Entergy Arkansas recorded a regulatory liability of $8.8 million to reflect the amount of the 2025 historical year netting adjustment that it collected from customers during the 2025 rate effective period. Generating Arkansas Jobs Act Rider In March 2026, Entergy Arkansas filed its first annual update to the strategic investment recovery rider, requesting recovery of $110.4 million of financing costs during construction of generation and transmission strategic investments related to Ironwood Power Station, Jefferson Power Station, and the Arkansas Cypress Solar facility. The revised rates were requested to be effective with the first billing cycle of June 2026. In April 2026 the APSC general staff filed testimony arguing that the APSC had not issued an order designating Ironwood Power Station as a strategic investment and that related costs should therefore be removed from the annual update. Also in April 2026, Entergy Arkansas filed testimony asserting that the APSC general staff’s position is contrary to the plain language of the statute, which includes an exception for facilities like Ironwood Power Station that were certified by the APSC within a certain timeframe. A hearing was held in April 2026. In June 2026 the APSC approved Entergy Arkansas’s annual update, and rates became effective June 4, 2026. Production Tax Credit Tariffs As discussed in Note 3 to the financial statements in the Form 10-K, in January 2026 the APSC opened a docket to investigate the sale of Entergy Arkansas’s nuclear production tax credits and the appropriate ratemaking treatment of production tax credits for all of Entergy Arkansas’s eligible resources, including how the proceeds of any sales should flow through to customers. For nuclear production tax credits, Entergy Arkansas proposed a nuclear production tax credit rider, which would provide for the immediate flow through to customers of the weighted average cost of capital return on the net proceeds of the monetized nuclear production tax credits. Recognizing that the timing and determination from the IRS is uncertain, the nuclear production tax credit rider also proposes that, if there is an unfavorable IRS determination, Entergy Arkansas would collect applicable costs from customers. As directed by the APSC, in February 2026, Entergy Arkansas submitted a compliance filing to the APSC verifying the status of the solar production tax credits. The filing also verified that the net proceeds from the sale of the nuclear production tax credits were recorded in FERC accounts that are accruing a return for customers’ benefit at a rate that is above the customer deposit rate. Subsequently, in March 2026, Entergy Arkansas filed testimony setting forth its proposal for the solar production tax credits. Specifically, Entergy Arkansas requested the same ratemaking treatment for all of the solar facilities that the APSC already approved for Walnut Bend (i.e., the total net monetized proceeds from production tax credits expected to be generated over the first ten years of a solar facility’s operation are estimated and then amortized over the expected useful life of the asset, which is typically 30 years). Additionally, consistent with prior orders for these resources, the regulatory liabilities associated with the net cash proceeds from monetized solar production tax credits will be included in Entergy Arkansas’s calculation of its weighted average cost of capital providing a return on the unamortized balance for the benefit of customers. Further, Entergy Arkansas proposes to flow the benefits of the solar production tax credits to customers through Entergy Arkansas’s formula rate plan, effective with the formula rate plan rates that will go into effect January 1, 2027. Entergy Arkansas’s proposal would result in the benefits of the production tax credits being passed through to customers, if approved, as reductions in revenue requirement evenly over the life of the assets, rather than only during the 10-year period in which the production tax credits are generated. In April 2026 the APSC general staff filed testimony proposing an amortization period of no more than 15 years for the monetized proceeds for the tax credits associated with the West Memphis Solar and Driver Solar facilities. An evidentiary hearing was held in July 2026, but was not completed. The APSC is to set a date to complete the hearing. Special Rate Contract and Arkansas Cypress Solar As discussed in the Form 10-K, in September 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of the Arkansas Cypress Solar facility, a planned 600 MW solar photovoltaic array with a 350 MW battery energy storage system and associated transmission facilities interconnecting at Entergy Arkansas’s White Bluff substation. The estimated cost of the project is $1,602 million. In March 2026 the APSC approved the Arkansas Cypress Solar facility and Entergy Arkansas’s recovery of the costs of the facility through the Generating Arkansas Jobs Act rider. The APSC also ordered implementation of an independent monitor to oversee costs. In April 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of costs. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including the Arkansas Cypress Solar facility, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates. No alternative recommendations were made by the other parties. The facility is expected to be in service by the end of 2028. Filings with the LPSC (Entergy Louisiana) Retail Rates Resilience Plan Cost Recovery Rider In December 2022, Entergy Louisiana filed an application with the LPSC seeking a public interest finding regarding Phase I of Entergy Louisiana’s Future Ready resilience plan and approval of a rider mechanism to recover the program’s costs. Phase I in the December 2022 application reflected the first five years of a ten-year resilience plan and included investment of approximately $5 billion, including hardening investment, transmission dead-end structures, enhanced vegetation management, and telecommunications improvement. In April 2024 the LPSC approved a framework which includes an initial five-year resilience plan providing for an investment of approximately $1.9 billion with cost recovery via a forward-looking rider with semi-annual true-ups. The plan is subject to specified reporting requirements and includes a performance review of the hardened assets. The LPSC order approving the framework does not include any restrictions on Entergy Louisiana’s ability to file applications for approval of additional investments in resilience. In January 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $40.4 million, or $38.9 million in incremental annual revenues from Entergy Louisiana’s first semi-annual filing in July 2024, for projects expected to be placed in service during the rate-effective period of March 2025 through August 2025. In February 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $50.2 million, or $9.8 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2025 through February 2026. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $5.6 million to be implemented in the January 2026 semi-annual filing. In August 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In January 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $101.8 million, or $51.6 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of March 2026 through August 2026. Additionally, Entergy Louisiana’s true-up filing included an over-recovery totaling $16.6 million to be implemented in the July 2026 semi-annual filing. In February 2026 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $114.2 million, or $12.4 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2026 through February 2027. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $2.5 million to be implemented in the January 2027 semi-annual filing. The LPSC staff is reviewing the filed rider rates. Vegetation Management Rider In November 2025 the LPSC staff issued notice of its initiation of a rulemaking to implement a vegetation management pilot program for LPSC jurisdictional electric utilities. The pilot program would be voluntary and would allow utilities to establish a rider for distribution vegetation management for up to 100% of the utility’s prior calendar year vegetation management spending. The rider may not exceed 1% of a customer’s bill, and the utility would be required to maintain its prior calendar year level of spending on vegetation management as reflected in its base rates or formula rate plan. In February 2026 the LPSC staff filed a report and recommendation along with a proposed final rule providing for the adoption of the pilot program consistent with the terms outlined in the original notice. In March 2026 the LPSC voted to accept the LPSC staff’s recommendation and adopt the proposed pilot program as presented. In April 2026, Entergy Louisiana filed its vegetation management rider for the rate-effective period of May 2026 through December 2026, which included a revenue requirement of $20 million for incremental spending on distribution vegetation management above the prior calendar year level of spending on vegetation management. 2025 Formula Rate Plan Filing In June 2026, Entergy Louisiana filed its formula rate plan evaluation report for its 2025 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 2025, the formula produced an earned return on equity of 9.63%, which falls within the established bandwidth and therefore results in no adjustment to base rider formula rate plan revenue. Additional changes in formula rate plan revenue include: (1) the removal of approximately $73 million in annual customer credits associated with the global stipulated settlement agreement, which have been fully credited to customers in accordance with the agreement; (2) a reduction in customer credits through the tax adjustment mechanism, attributable to the return of Entergy Louisiana’s over-collection of income tax expense associated with Louisiana state tax law changes effective in 2025 and the expiration of certain ad valorem exemptions; (3) increases in transmission and distribution plant in service, as recognized through the transmission and distribution recovery mechanisms, including restoration costs from Winter Storm Fern, for which Entergy Louisiana does not intend to seek relief or exception to the formula rate plan; (4) increases to the additional capacity mechanism; and (5) the final phase-in of additional nuclear depreciation expense, in accordance with the global stipulated settlement agreement. See Note 2 to the financial statements in the Form 10-K for discussion of the global stipulated settlement agreement. Collectively, these factors contributed to a net increase of $222 million in formula rate plan revenue for the period. Subject to LPSC review, the resulting changes from the 2025 formula rate plan evaluation report will become effective for bills rendered during the first billing cycle of September 2026, subject to refund. Request for Extension of Formula Rate Plan In June 2026, Entergy Louisiana submitted a motion requesting the LPSC approve a one-year extension of its current formula rate plan, with all material provisions left unchanged, including the allowed return on common equity of 9.7% with a bandwidth of 40 basis points above and below the midpoint. Entergy Louisiana has requested LPSC action on the proposed extension by August 2026. River Bend Deregulated Asset Plan Filing In September 2025, Entergy Louisiana filed an application seeking LPSC approval to recover from customers, prospectively, approximately $49 million in annual revenues associated with the Louisiana retail deregulated portion of River Bend. Costs associated with the deregulated portion of River Bend have historically been excluded from retail ratemaking as a result of a 1988 LPSC decision. Instead, Entergy Louisiana has been allowed by the LPSC to either recover 4.6 cents per kWh for the power generated from that portion of the plant, or sell the power into the applicable market (subject to certain restrictions). The filing presents evidence that River Bend is a cost-effective and prudent source of needed baseload supply with value to Entergy Louisiana customers and seeks to recover the previously excluded costs, on a prospective basis. In March 2026 the LPSC staff and certain intervenors filed direct testimony recommending that the LPSC deny Entergy Louisiana’s application. The LPSC staff’s testimony further recommends that, if the LPSC were to grant any relief, notwithstanding the LPSC staff’s recommendation, such relief should be limited to allowing only prospective capital additions at River Bend to be included in Entergy Louisiana’s customer rates. Entergy Louisiana’s rebuttal testimony is due in August 2026. A hearing is scheduled for January 2027. Filings with the MPSC (Entergy Mississippi) Retail Rates 2026 Formula Rate Plan Filing In February 2026, Entergy Mississippi submitted its formula rate plan 2026 test year filing and 2025 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2025 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2026 calendar year to also be within the formula rate plan bandwidth. The 2026 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2025 look-back filing compared actual 2025 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 $293 thousand to reflect one outside-the-bandwidth change, a true-up of demand side management costs. In June 2026, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2026 test year filing, with the exception of immaterial adjustments to certain operations and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2026, resulting in no change in formula rate plan revenues for 2026. Pursuant to the stipulation, Entergy Mississippi’s 2025 look-back filing reflected an earned return on rate base of 8.10%, which also resulted in no change in formula rate plan revenues for 2025. In addition, the stipulation included the recovery of the outside-the-bandwidth change discussed above as well as the ratemaking treatment of certain customer contributions, the mechanism for recovery of the benefits of nuclear production tax credits, and the realignment of the first project from the interim facilities rate adjustment to the formula rate plan. In June 2026 the MPSC approved the joint stipulation with rates effective in July 2026. See Note 10 to the financial statements herein for further discussion of the mechanism for recovery of the benefits of nuclear production tax credits included in the joint stipulation. Filings with the City Council (Entergy New Orleans) Retail Rates 2026 Formula Rate Plan Filing In April 2026, Entergy New Orleans submitted to the City Council its formula rate plan 2025 test year filing. The 2025 evaluation report produced an earned return on equity of 7.55% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in an increase in rates of $16.6 million. The increase in rates is driven, in part, by an increase in plant in service, as well as the cost of known and measurable capital additions. The increase is also driven by a decrease in total revenues due to a decline in kWh sales. The filing is subject to a 75-day review and discovery period followed by a 25-day period to resolve any disputes among the parties. In July 2026 the City Council’s advisors issued a report seeking a reduction in Entergy New Orleans’s requested formula rate plan revenues of approximately $4.4 million due to certain proposed cost realignments, imputation of revenues, and disallowances. The City Council’s advisors also recommended that Entergy New Orleans be permitted to collect $20 million over five years beginning in September 2026 to recover amounts that it might be required to pay Entergy Louisiana and Entergy Arkansas pursuant to a FERC order issued in June 2026, relating to an alleged MSS-4 replacement tariff (MSS-4R) violation. However, the FERC order is unclear on its face, and the specific amount of a payment, if any, is unknown. Requests for rehearing and clarification of the FERC order are pending. See “MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding” below for additional discussion of the FERC order. If any rate adjustments are not resolved, the City Council would set a procedural schedule to resolve such disputes. A response by Entergy New Orleans to the advisors’ report is due in August 2026. Resulting rates will be effective with the first billing cycle of September 2026 pursuant to the formula rate plan tariff. Request for Extension of Formula Rate Plan In July 2026, Entergy New Orleans submitted a motion requesting the City Council approve a four-year extension of its current formula rate plan, with all material provisions left unchanged, including the authorized return on equity of 9.35% with a bandwidth of 50 basis points above and below the midpoint. Entergy New Orleans has requested City Council action on the proposed extension by August 2026. Filings with the PUCT and Texas Cities (Entergy Texas) Retail Rates Distribution Cost Recovery Factor (DCRF) Rider In April 2026, 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 $112.5 million annually, or $20.4 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2025 and December 31, 2025. In July 2026 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after July 8, 2026. Transmission Cost Recovery Factor (TCRF) Rider As discussed in the Form 10-K, in October 2025, Entergy Texas filed with the PUCT a request to amend its TCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $30.3 million annually, or $20.6 million in incremental annual revenues beyond Entergy Texas’s then-effective TCRF rider based on its capital invested in transmission between July 1, 2024 and June 30, 2025 and changes in other transmission charges. In April 2026 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 6, 2026. Generation Cost Recovery Rider In March 2026, Entergy Texas filed an application to establish a generation cost recovery rider to begin recovering a return of and on its capital investment in the Orange County Advanced Power Station. The proposed generation cost recovery rider, which includes Entergy Texas’s capital invested in generation for the Orange County Advanced Power Station through December 31, 2025, is designed to collect approximately $150.4 million annually from Entergy Texas’s retail customers. By statute, the proposed generation cost recovery rider rates are to become effective when the Orange County Advanced Power Station is placed into service, which is expected in third quarter 2026. In July 2026 the ALJ with the State Office of Administrative Hearings approved a proposed procedural schedule that includes a hearing on the merits in September 2026 and provides for interim rates to become effective for usage on and after the Orange County Advanced Power Station in-service date, to the extent final rates are not in place by that time. Capacity Cost Recovery Rider (CCRR) In May 2026, Entergy Texas filed with the PUCT a request to establish a new CCRR. The proposed CCRR is designed to collect approximately $58 million annually from Entergy Texas’s retail customers based on Entergy Texas’s eligible capacity-related costs and revenues for the 12 months beginning June 1, 2026. The eligible capacity-related costs and revenues are associated with Entergy Texas’s participation in MISO’s annual planning resource auction. In July 2026 the PUCT approved the CCRR, consistent with Entergy Texas’s as-filed request, and rates became effective on July 10, 2026. Entergy Arkansas Opportunity Sales Proceeding See Note 2 to the financial statements in the Form 10-K for discussion of the Entergy Arkansas opportunity sales proceeding. Complaints Against System Energy See Note 2 to the financial statements in the Form 10-K for information regarding complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. Unit Power Sales Agreement See Note 2 to the financial statements in the Form 10-K for discussion of the Unit Power Sales Agreement. The following is an update to that discussion. Pension Costs Amendment Proceeding As discussed in the Form 10-K, in October 2021, System Energy submitted to the FERC proposed amendments to the Unit Power Sales Agreement to include in rate base the prepaid and accrued pension costs associated with System Energy’s qualified pension plans. In November 2025 the FERC issued an order approving System Energy’s proposed prepaid and accrued pension recovery mechanism. System Energy has been utilizing this methodology in billings since December 1, 2022 and will continue to utilize it going forward. As a result of the FERC’s order, System Energy did not owe any refunds. In December 2025 the APSC filed a request for rehearing of the November 2025 order. In January 2026 the FERC denied the APSC’s rehearing request by operation of law. In May 2026 the FERC issued a follow-up substantive order denying the APSC’s rehearing and sustaining its finding that no refunds are owed. 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-4R net operating loss carryforward proceeding. The following is an update to that discussion. As discussed in the Form 10-K, in October 2021 the LPSC filed a complaint with the FERC alleging that Entergy Services improperly excluded net operating loss carryforward accumulated deferred income taxes (NOLC ADIT) from MSS-4R rates in the period before March 20, 2021. The LPSC argued that sales from Entergy Louisiana to Entergy Texas and Entergy New Orleans were charged at rates lower than they otherwise should have been, and it accordingly seeks surcharges for the period prior to March 20, 2021. The FERC set the complaint for hearing procedures and subsequently the hearing for this complaint proceeding was consolidated with the hearing procedures for Entergy Services’ January 2021 NOLC ADIT filing. Testimony was filed by parties in 2023, and the hearing before a FERC ALJ was concluded in February 2024. In June 2024, the FERC ALJ issued an initial decision addressing three major issues: (1) whether Entergy Services’ proposed prospective inclusion and allocation of NOLC ADIT in MSS-4R rates using a modified with-and-without methodology is just and reasonable; (2) whether Entergy Services correctly calculated excess and deficient accumulated deferred income taxes in accordance with the terms of a prior settlement; and (3) whether NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the January 2021 MSS-4R filing. With respect to issues (1) and (2), the presiding ALJ concluded that Entergy Services’ proposed methodology for allocating and including NOLC ADIT in MSS-4R rates was just and reasonable and that Entergy Services correctly performed the excess and deficient accumulated deferred income taxes calculations. With respect to issue (3), however, the presiding ALJ agreed with the LPSC that NOLC ADIT should have been included in MSS-4R rates since September 1, 2016, and as a result, the presiding ALJ ordered that Entergy Louisiana and Entergy Arkansas recalculate bills for the period of September 1, 2016 through November 11, 2023 with surcharges expected to be due to those operating companies from the purchasing operating companies, Entergy New Orleans, Entergy Texas, and Entergy Louisiana (for some Entergy Arkansas sales). The presiding ALJ also ordered Entergy Services to pay the interest owed to Entergy Louisiana on these surcharges. The surcharge methodology that the presiding ALJ recommended in connection with issue (3) was not supported by any participant in the hearing. As part of their exceptions to the initial decision, all parties to the proceeding opposed the use of the ALJ’s methodology, except for the FERC trial staff, which took no position. During the hearing, the LPSC and the FERC trial staff advocated that the alleged tariff violation should be remedied by the application of Entergy Services’ January 2021 proposed methodology. All other parties, including the PUCT, the City Council, and Entergy Services, opposed any surcharges for the period prior to the March 20, 2021 effective date of the January 2021 filing. Entergy Services disputed the presiding ALJ's rulings on issue (3) and filed exceptions to these rulings in July 2024. In June 2026 the FERC issued its opinion largely affirming the initial decision. Specifically, the FERC found the historic exclusion of NOLC ADIT from MSS-4R rates was a tariff violation and ordered Entergy Louisiana and Entergy Arkansas to provide refunds and/or surcharges, as appropriate, for the period from September 1, 2016 through November 12, 2023 for sales by Entergy Louisiana and for the period December 19, 2013 until May 13, 2024 for sales by Entergy Arkansas. The FERC also ordered the relevant operating company to pay interest on the amounts owed. In July 2026, Entergy Services, along with the LPSC, the City Council, and the PUCT, filed for rehearing and clarification of the FERC’s order. Entergy Services continues to dispute that the NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the tariff amendment filing. Moreover, because of ambiguity in the order and the pending rehearing and clarification requests, it is unclear whether Entergy Arkansas and Entergy Louisiana as sellers will receive surcharges or have to provide refunds. Specifically, there is a lack of clarity as to whether plant-related liability accumulated deferred income taxes must be included in calculating refunds/surcharges. Entergy Services also identified a lack of clarity regarding including the nuclear decommissioning liability deduction in the NOLC ADIT calculation. Depending on the guidance issued by the FERC in response to the request for rehearing and clarification of its June 2026 order, each of the affected Entergy operating companies could either receive material refunds or owe material surcharges. As such, any amounts payable or receivable between the Entergy operating companies that may result from the order are not reasonably estimable as of June 30, 2026. MSS-4 Replacement Tariff – River Bend 70 Depreciation LPSC Complaint In May 2026 the LPSC filed a complaint with the FERC alleging that Entergy Texas owes surcharges to Entergy Louisiana because the depreciation rates used in the MSS-4R for the River Bend 70 sales of capacity and energy were based on a directive of the PUCT for the period from September 1, 2016 to December 31, 2025. The LPSC quantifies the potential surcharge as $100 million, inclusive of interest. Entergy Services disputes that any surcharges are due from Entergy Texas to Entergy Louisiana. In June 2026, Entergy Services filed a motion to dismiss and answer to the complaint submitted by the LPSC. Joint Targeted Interconnection Queue Cost Allocation Dispute In April 2026, MISO submitted to the FERC an unexecuted agreement proposing to assign to Entergy Texas (in its capacity as the owner of the Legend Power Station) costs associated with the MISO and Southwest Power Pool Joint Targeted Interconnection Queue. Entergy Texas estimates that MISO’s proposed cost assignment would result in total charges of approximately $112 million, paid over twenty years beginning in 2031. In May 2026, Entergy Texas filed a protest to the agreement, as well as a separate complaint at the FERC, arguing that the proposed cost allocation is not just and reasonable. In June 2026 the FERC issued a deficiency notice to MISO. In July 2026, MISO and Southwest Power Pool filed answers to the complaint, and MISO filed an answer to the deficiency letter. Protests and comments in response to MISO’s answer to the deficiency letter are due in August 2026.

Public Utilities Disclosure [Text Block]	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 2026, 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 $0.01333 per kWh to $0.01508 per kWh. The primary reason for the rate increase was an under-recovered balance as a result of higher natural gas prices in 2025. Based on circumstances related to ANO 2’s refueling outage, Entergy Arkansas made an adjustment to projected energy costs to phase-in the rate increase gradually. The redetermined rate of $0.01508 per kWh became effective with the first billing cycle in April 2026 through the normal operation of the tariff. Entergy Louisiana As discussed in the Form 10-K, in June 2025 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings (for Entergy Louisiana’s gas operations). The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from January 2023 through June 2025. The LPSC staff issued its audit report in March 2026. The next step is for the LPSC to issue its final report, but there is no deadline or timing requirement associated with the issuance of the final report. In February 2026, Entergy Louisiana, in its monthly filing to update its fuel adjustment clause, requested to defer approximately $141.9 million of fuel costs incurred in January 2026 that were primarily attributable to the effects of Winter Storm Fern, consistent with the LPSC’s general order approved at its February 2026 meeting permitting temporary modifications to the LPSC’s fuel adjustment clause general order. The filing proposed to defer the recovery of these fuel costs over a four-month period from March 2026 through June 2026 to mitigate the customer bill impacts of these fuel costs. In March 2026 the LPSC issued a special order delegating authority to the LPSC executive secretary to review and approve utility-specific requests for deferral of fuel costs from Winter Storm Fern, subject to audit as per the LPSC’s fuel clause general order. In April 2026 the LPSC executive secretary approved Entergy Louisiana’s request for deferral. In April 2026 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2023 through 2025. Discovery is ongoing, and no audit report has been filed. 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 2026 Base Rate Case In February 2026, Entergy Arkansas filed with the APSC a general change in rates, charges, and tariffs. The filing requested a base rate increase to recover a base rate revenue deficiency of $44.6 million and notified the APSC of Entergy Arkansas’s intent to implement a forward test year formula rate plan pursuant to Arkansas legislation passed in 2015. The primary drivers of the revenue deficiency were increased depreciation expense and the impact of net capital additions. Additionally, the filing requested a 9.90% return on common equity and increased depreciation rates as the result of a depreciation study. In March 2026 the APSC issued an order suspending the proposed rates and tariffs filed by Entergy Arkansas. In June 2026 the APSC established a procedural schedule with an evidentiary hearing scheduled to begin in November 2026, and in July 2026 a number of intervenors moved to modify the schedule to conduct additional discovery. Entergy Arkansas opposed the motion in part based on the voluminous discovery conducted to date. 2026 Formula Rate Plan Filing In July 2026, Entergy Arkansas filed with the APSC its 2026 formula rate plan filing to set its formula rate for the 2027 calendar year. The filing contained an evaluation of Entergy Arkansas’s earnings and a netting adjustment for the 2025 historical year. The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2025 historical year was 8.8%, resulting in a $47.2 million formula rate plan revenue increase to produce a 9.65% earned rate of return on common equity. When combined with 2025 historical year formula rate plan revenues of $56.0 million, the total proposed revenue change for the 2025 historical year netting adjustment is a reduction of $8.8 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. Entergy Arkansas’s revenue requirement in this filing did not exceed the constraint. In second quarter 2026, Entergy Arkansas recorded a regulatory liability of $8.8 million to reflect the amount of the 2025 historical year netting adjustment that it collected from customers during the 2025 rate effective period. Generating Arkansas Jobs Act Rider In March 2026, Entergy Arkansas filed its first annual update to the strategic investment recovery rider, requesting recovery of $110.4 million of financing costs during construction of generation and transmission strategic investments related to Ironwood Power Station, Jefferson Power Station, and the Arkansas Cypress Solar facility. The revised rates were requested to be effective with the first billing cycle of June 2026. In April 2026 the APSC general staff filed testimony arguing that the APSC had not issued an order designating Ironwood Power Station as a strategic investment and that related costs should therefore be removed from the annual update. Also in April 2026, Entergy Arkansas filed testimony asserting that the APSC general staff’s position is contrary to the plain language of the statute, which includes an exception for facilities like Ironwood Power Station that were certified by the APSC within a certain timeframe. A hearing was held in April 2026. In June 2026 the APSC approved Entergy Arkansas’s annual update, and rates became effective June 4, 2026. Production Tax Credit Tariffs As discussed in Note 3 to the financial statements in the Form 10-K, in January 2026 the APSC opened a docket to investigate the sale of Entergy Arkansas’s nuclear production tax credits and the appropriate ratemaking treatment of production tax credits for all of Entergy Arkansas’s eligible resources, including how the proceeds of any sales should flow through to customers. For nuclear production tax credits, Entergy Arkansas proposed a nuclear production tax credit rider, which would provide for the immediate flow through to customers of the weighted average cost of capital return on the net proceeds of the monetized nuclear production tax credits. Recognizing that the timing and determination from the IRS is uncertain, the nuclear production tax credit rider also proposes that, if there is an unfavorable IRS determination, Entergy Arkansas would collect applicable costs from customers. As directed by the APSC, in February 2026, Entergy Arkansas submitted a compliance filing to the APSC verifying the status of the solar production tax credits. The filing also verified that the net proceeds from the sale of the nuclear production tax credits were recorded in FERC accounts that are accruing a return for customers’ benefit at a rate that is above the customer deposit rate. Subsequently, in March 2026, Entergy Arkansas filed testimony setting forth its proposal for the solar production tax credits. Specifically, Entergy Arkansas requested the same ratemaking treatment for all of the solar facilities that the APSC already approved for Walnut Bend (i.e., the total net monetized proceeds from production tax credits expected to be generated over the first ten years of a solar facility’s operation are estimated and then amortized over the expected useful life of the asset, which is typically 30 years). Additionally, consistent with prior orders for these resources, the regulatory liabilities associated with the net cash proceeds from monetized solar production tax credits will be included in Entergy Arkansas’s calculation of its weighted average cost of capital providing a return on the unamortized balance for the benefit of customers. Further, Entergy Arkansas proposes to flow the benefits of the solar production tax credits to customers through Entergy Arkansas’s formula rate plan, effective with the formula rate plan rates that will go into effect January 1, 2027. Entergy Arkansas’s proposal would result in the benefits of the production tax credits being passed through to customers, if approved, as reductions in revenue requirement evenly over the life of the assets, rather than only during the 10-year period in which the production tax credits are generated. In April 2026 the APSC general staff filed testimony proposing an amortization period of no more than 15 years for the monetized proceeds for the tax credits associated with the West Memphis Solar and Driver Solar facilities. An evidentiary hearing was held in July 2026, but was not completed. The APSC is to set a date to complete the hearing. Special Rate Contract and Arkansas Cypress Solar As discussed in the Form 10-K, in September 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of the Arkansas Cypress Solar facility, a planned 600 MW solar photovoltaic array with a 350 MW battery energy storage system and associated transmission facilities interconnecting at Entergy Arkansas’s White Bluff substation. The estimated cost of the project is $1,602 million. In March 2026 the APSC approved the Arkansas Cypress Solar facility and Entergy Arkansas’s recovery of the costs of the facility through the Generating Arkansas Jobs Act rider. The APSC also ordered implementation of an independent monitor to oversee costs. In April 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of costs. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including the Arkansas Cypress Solar facility, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates. No alternative recommendations were made by the other parties. The facility is expected to be in service by the end of 2028. Filings with the LPSC (Entergy Louisiana) Retail Rates Resilience Plan Cost Recovery Rider In December 2022, Entergy Louisiana filed an application with the LPSC seeking a public interest finding regarding Phase I of Entergy Louisiana’s Future Ready resilience plan and approval of a rider mechanism to recover the program’s costs. Phase I in the December 2022 application reflected the first five years of a ten-year resilience plan and included investment of approximately $5 billion, including hardening investment, transmission dead-end structures, enhanced vegetation management, and telecommunications improvement. In April 2024 the LPSC approved a framework which includes an initial five-year resilience plan providing for an investment of approximately $1.9 billion with cost recovery via a forward-looking rider with semi-annual true-ups. The plan is subject to specified reporting requirements and includes a performance review of the hardened assets. The LPSC order approving the framework does not include any restrictions on Entergy Louisiana’s ability to file applications for approval of additional investments in resilience. In January 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $40.4 million, or $38.9 million in incremental annual revenues from Entergy Louisiana’s first semi-annual filing in July 2024, for projects expected to be placed in service during the rate-effective period of March 2025 through August 2025. In February 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $50.2 million, or $9.8 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2025 through February 2026. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $5.6 million to be implemented in the January 2026 semi-annual filing. In August 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In January 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $101.8 million, or $51.6 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of March 2026 through August 2026. Additionally, Entergy Louisiana’s true-up filing included an over-recovery totaling $16.6 million to be implemented in the July 2026 semi-annual filing. In February 2026 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $114.2 million, or $12.4 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2026 through February 2027. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $2.5 million to be implemented in the January 2027 semi-annual filing. The LPSC staff is reviewing the filed rider rates. Vegetation Management Rider In November 2025 the LPSC staff issued notice of its initiation of a rulemaking to implement a vegetation management pilot program for LPSC jurisdictional electric utilities. The pilot program would be voluntary and would allow utilities to establish a rider for distribution vegetation management for up to 100% of the utility’s prior calendar year vegetation management spending. The rider may not exceed 1% of a customer’s bill, and the utility would be required to maintain its prior calendar year level of spending on vegetation management as reflected in its base rates or formula rate plan. In February 2026 the LPSC staff filed a report and recommendation along with a proposed final rule providing for the adoption of the pilot program consistent with the terms outlined in the original notice. In March 2026 the LPSC voted to accept the LPSC staff’s recommendation and adopt the proposed pilot program as presented. In April 2026, Entergy Louisiana filed its vegetation management rider for the rate-effective period of May 2026 through December 2026, which included a revenue requirement of $20 million for incremental spending on distribution vegetation management above the prior calendar year level of spending on vegetation management. 2025 Formula Rate Plan Filing In June 2026, Entergy Louisiana filed its formula rate plan evaluation report for its 2025 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 2025, the formula produced an earned return on equity of 9.63%, which falls within the established bandwidth and therefore results in no adjustment to base rider formula rate plan revenue. Additional changes in formula rate plan revenue include: (1) the removal of approximately $73 million in annual customer credits associated with the global stipulated settlement agreement, which have been fully credited to customers in accordance with the agreement; (2) a reduction in customer credits through the tax adjustment mechanism, attributable to the return of Entergy Louisiana’s over-collection of income tax expense associated with Louisiana state tax law changes effective in 2025 and the expiration of certain ad valorem exemptions; (3) increases in transmission and distribution plant in service, as recognized through the transmission and distribution recovery mechanisms, including restoration costs from Winter Storm Fern, for which Entergy Louisiana does not intend to seek relief or exception to the formula rate plan; (4) increases to the additional capacity mechanism; and (5) the final phase-in of additional nuclear depreciation expense, in accordance with the global stipulated settlement agreement. See Note 2 to the financial statements in the Form 10-K for discussion of the global stipulated settlement agreement. Collectively, these factors contributed to a net increase of $222 million in formula rate plan revenue for the period. Subject to LPSC review, the resulting changes from the 2025 formula rate plan evaluation report will become effective for bills rendered during the first billing cycle of September 2026, subject to refund. Request for Extension of Formula Rate Plan In June 2026, Entergy Louisiana submitted a motion requesting the LPSC approve a one-year extension of its current formula rate plan, with all material provisions left unchanged, including the allowed return on common equity of 9.7% with a bandwidth of 40 basis points above and below the midpoint. Entergy Louisiana has requested LPSC action on the proposed extension by August 2026. River Bend Deregulated Asset Plan Filing In September 2025, Entergy Louisiana filed an application seeking LPSC approval to recover from customers, prospectively, approximately $49 million in annual revenues associated with the Louisiana retail deregulated portion of River Bend. Costs associated with the deregulated portion of River Bend have historically been excluded from retail ratemaking as a result of a 1988 LPSC decision. Instead, Entergy Louisiana has been allowed by the LPSC to either recover 4.6 cents per kWh for the power generated from that portion of the plant, or sell the power into the applicable market (subject to certain restrictions). The filing presents evidence that River Bend is a cost-effective and prudent source of needed baseload supply with value to Entergy Louisiana customers and seeks to recover the previously excluded costs, on a prospective basis. In March 2026 the LPSC staff and certain intervenors filed direct testimony recommending that the LPSC deny Entergy Louisiana’s application. The LPSC staff’s testimony further recommends that, if the LPSC were to grant any relief, notwithstanding the LPSC staff’s recommendation, such relief should be limited to allowing only prospective capital additions at River Bend to be included in Entergy Louisiana’s customer rates. Entergy Louisiana’s rebuttal testimony is due in August 2026. A hearing is scheduled for January 2027. Filings with the MPSC (Entergy Mississippi) Retail Rates 2026 Formula Rate Plan Filing In February 2026, Entergy Mississippi submitted its formula rate plan 2026 test year filing and 2025 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2025 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2026 calendar year to also be within the formula rate plan bandwidth. The 2026 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2025 look-back filing compared actual 2025 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 $293 thousand to reflect one outside-the-bandwidth change, a true-up of demand side management costs. In June 2026, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2026 test year filing, with the exception of immaterial adjustments to certain operations and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2026, resulting in no change in formula rate plan revenues for 2026. Pursuant to the stipulation, Entergy Mississippi’s 2025 look-back filing reflected an earned return on rate base of 8.10%, which also resulted in no change in formula rate plan revenues for 2025. In addition, the stipulation included the recovery of the outside-the-bandwidth change discussed above as well as the ratemaking treatment of certain customer contributions, the mechanism for recovery of the benefits of nuclear production tax credits, and the realignment of the first project from the interim facilities rate adjustment to the formula rate plan. In June 2026 the MPSC approved the joint stipulation with rates effective in July 2026. See Note 10 to the financial statements herein for further discussion of the mechanism for recovery of the benefits of nuclear production tax credits included in the joint stipulation. Filings with the City Council (Entergy New Orleans) Retail Rates 2026 Formula Rate Plan Filing In April 2026, Entergy New Orleans submitted to the City Council its formula rate plan 2025 test year filing. The 2025 evaluation report produced an earned return on equity of 7.55% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in an increase in rates of $16.6 million. The increase in rates is driven, in part, by an increase in plant in service, as well as the cost of known and measurable capital additions. The increase is also driven by a decrease in total revenues due to a decline in kWh sales. The filing is subject to a 75-day review and discovery period followed by a 25-day period to resolve any disputes among the parties. In July 2026 the City Council’s advisors issued a report seeking a reduction in Entergy New Orleans’s requested formula rate plan revenues of approximately $4.4 million due to certain proposed cost realignments, imputation of revenues, and disallowances. The City Council’s advisors also recommended that Entergy New Orleans be permitted to collect $20 million over five years beginning in September 2026 to recover amounts that it might be required to pay Entergy Louisiana and Entergy Arkansas pursuant to a FERC order issued in June 2026, relating to an alleged MSS-4 replacement tariff (MSS-4R) violation. However, the FERC order is unclear on its face, and the specific amount of a payment, if any, is unknown. Requests for rehearing and clarification of the FERC order are pending. See “MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding” below for additional discussion of the FERC order. If any rate adjustments are not resolved, the City Council would set a procedural schedule to resolve such disputes. A response by Entergy New Orleans to the advisors’ report is due in August 2026. Resulting rates will be effective with the first billing cycle of September 2026 pursuant to the formula rate plan tariff. Request for Extension of Formula Rate Plan In July 2026, Entergy New Orleans submitted a motion requesting the City Council approve a four-year extension of its current formula rate plan, with all material provisions left unchanged, including the authorized return on equity of 9.35% with a bandwidth of 50 basis points above and below the midpoint. Entergy New Orleans has requested City Council action on the proposed extension by August 2026. Filings with the PUCT and Texas Cities (Entergy Texas) Retail Rates Distribution Cost Recovery Factor (DCRF) Rider In April 2026, 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 $112.5 million annually, or $20.4 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2025 and December 31, 2025. In July 2026 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after July 8, 2026. Transmission Cost Recovery Factor (TCRF) Rider As discussed in the Form 10-K, in October 2025, Entergy Texas filed with the PUCT a request to amend its TCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $30.3 million annually, or $20.6 million in incremental annual revenues beyond Entergy Texas’s then-effective TCRF rider based on its capital invested in transmission between July 1, 2024 and June 30, 2025 and changes in other transmission charges. In April 2026 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 6, 2026. Generation Cost Recovery Rider In March 2026, Entergy Texas filed an application to establish a generation cost recovery rider to begin recovering a return of and on its capital investment in the Orange County Advanced Power Station. The proposed generation cost recovery rider, which includes Entergy Texas’s capital invested in generation for the Orange County Advanced Power Station through December 31, 2025, is designed to collect approximately $150.4 million annually from Entergy Texas’s retail customers. By statute, the proposed generation cost recovery rider rates are to become effective when the Orange County Advanced Power Station is placed into service, which is expected in third quarter 2026. In July 2026 the ALJ with the State Office of Administrative Hearings approved a proposed procedural schedule that includes a hearing on the merits in September 2026 and provides for interim rates to become effective for usage on and after the Orange County Advanced Power Station in-service date, to the extent final rates are not in place by that time. Capacity Cost Recovery Rider (CCRR) In May 2026, Entergy Texas filed with the PUCT a request to establish a new CCRR. The proposed CCRR is designed to collect approximately $58 million annually from Entergy Texas’s retail customers based on Entergy Texas’s eligible capacity-related costs and revenues for the 12 months beginning June 1, 2026. The eligible capacity-related costs and revenues are associated with Entergy Texas’s participation in MISO’s annual planning resource auction. In July 2026 the PUCT approved the CCRR, consistent with Entergy Texas’s as-filed request, and rates became effective on July 10, 2026. Entergy Arkansas Opportunity Sales Proceeding See Note 2 to the financial statements in the Form 10-K for discussion of the Entergy Arkansas opportunity sales proceeding. Complaints Against System Energy See Note 2 to the financial statements in the Form 10-K for information regarding complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. Unit Power Sales Agreement See Note 2 to the financial statements in the Form 10-K for discussion of the Unit Power Sales Agreement. The following is an update to that discussion. Pension Costs Amendment Proceeding As discussed in the Form 10-K, in October 2021, System Energy submitted to the FERC proposed amendments to the Unit Power Sales Agreement to include in rate base the prepaid and accrued pension costs associated with System Energy’s qualified pension plans. In November 2025 the FERC issued an order approving System Energy’s proposed prepaid and accrued pension recovery mechanism. System Energy has been utilizing this methodology in billings since December 1, 2022 and will continue to utilize it going forward. As a result of the FERC’s order, System Energy did not owe any refunds. In December 2025 the APSC filed a request for rehearing of the November 2025 order. In January 2026 the FERC denied the APSC’s rehearing request by operation of law. In May 2026 the FERC issued a follow-up substantive order denying the APSC’s rehearing and sustaining its finding that no refunds are owed. 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-4R net operating loss carryforward proceeding. The following is an update to that discussion. As discussed in the Form 10-K, in October 2021 the LPSC filed a complaint with the FERC alleging that Entergy Services improperly excluded net operating loss carryforward accumulated deferred income taxes (NOLC ADIT) from MSS-4R rates in the period before March 20, 2021. The LPSC argued that sales from Entergy Louisiana to Entergy Texas and Entergy New Orleans were charged at rates lower than they otherwise should have been, and it accordingly seeks surcharges for the period prior to March 20, 2021. The FERC set the complaint for hearing procedures and subsequently the hearing for this complaint proceeding was consolidated with the hearing procedures for Entergy Services’ January 2021 NOLC ADIT filing. Testimony was filed by parties in 2023, and the hearing before a FERC ALJ was concluded in February 2024. In June 2024, the FERC ALJ issued an initial decision addressing three major issues: (1) whether Entergy Services’ proposed prospective inclusion and allocation of NOLC ADIT in MSS-4R rates using a modified with-and-without methodology is just and reasonable; (2) whether Entergy Services correctly calculated excess and deficient accumulated deferred income taxes in accordance with the terms of a prior settlement; and (3) whether NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the January 2021 MSS-4R filing. With respect to issues (1) and (2), the presiding ALJ concluded that Entergy Services’ proposed methodology for allocating and including NOLC ADIT in MSS-4R rates was just and reasonable and that Entergy Services correctly performed the excess and deficient accumulated deferred income taxes calculations. With respect to issue (3), however, the presiding ALJ agreed with the LPSC that NOLC ADIT should have been included in MSS-4R rates since September 1, 2016, and as a result, the presiding ALJ ordered that Entergy Louisiana and Entergy Arkansas recalculate bills for the period of September 1, 2016 through November 11, 2023 with surcharges expected to be due to those operating companies from the purchasing operating companies, Entergy New Orleans, Entergy Texas, and Entergy Louisiana (for some Entergy Arkansas sales). The presiding ALJ also ordered Entergy Services to pay the interest owed to Entergy Louisiana on these surcharges. The surcharge methodology that the presiding ALJ recommended in connection with issue (3) was not supported by any participant in the hearing. As part of their exceptions to the initial decision, all parties to the proceeding opposed the use of the ALJ’s methodology, except for the FERC trial staff, which took no position. During the hearing, the LPSC and the FERC trial staff advocated that the alleged tariff violation should be remedied by the application of Entergy Services’ January 2021 proposed methodology. All other parties, including the PUCT, the City Council, and Entergy Services, opposed any surcharges for the period prior to the March 20, 2021 effective date of the January 2021 filing. Entergy Services disputed the presiding ALJ's rulings on issue (3) and filed exceptions to these rulings in July 2024. In June 2026 the FERC issued its opinion largely affirming the initial decision. Specifically, the FERC found the historic exclusion of NOLC ADIT from MSS-4R rates was a tariff violation and ordered Entergy Louisiana and Entergy Arkansas to provide refunds and/or surcharges, as appropriate, for the period from September 1, 2016 through November 12, 2023 for sales by Entergy Louisiana and for the period December 19, 2013 until May 13, 2024 for sales by Entergy Arkansas. The FERC also ordered the relevant operating company to pay interest on the amounts owed. In July 2026, Entergy Services, along with the LPSC, the City Council, and the PUCT, filed for rehearing and clarification of the FERC’s order. Entergy Services continues to dispute that the NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the tariff amendment filing. Moreover, because of ambiguity in the order and the pending rehearing and clarification requests, it is unclear whether Entergy Arkansas and Entergy Louisiana as sellers will receive surcharges or have to provide refunds. Specifically, there is a lack of clarity as to whether plant-related liability accumulated deferred income taxes must be included in calculating refunds/surcharges. Entergy Services also identified a lack of clarity regarding including the nuclear decommissioning liability deduction in the NOLC ADIT calculation. Depending on the guidance issued by the FERC in response to the request for rehearing and clarification of its June 2026 order, each of the affected Entergy operating companies could either receive material refunds or owe material surcharges. As such, any amounts payable or receivable between the Entergy operating companies that may result from the order are not reasonably estimable as of June 30, 2026. MSS-4 Replacement Tariff – River Bend 70 Depreciation LPSC Complaint In May 2026 the LPSC filed a complaint with the FERC alleging that Entergy Texas owes surcharges to Entergy Louisiana because the depreciation rates used in the MSS-4R for the River Bend 70 sales of capacity and energy were based on a directive of the PUCT for the period from September 1, 2016 to December 31, 2025. The LPSC quantifies the potential surcharge as $100 million, inclusive of interest. Entergy Services disputes that any surcharges are due from Entergy Texas to Entergy Louisiana. In June 2026, Entergy Services filed a motion to dismiss and answer to the complaint submitted by the LPSC. Joint Targeted Interconnection Queue Cost Allocation Dispute In April 2026, MISO submitted to the FERC an unexecuted agreement proposing to assign to Entergy Texas (in its capacity as the owner of the Legend Power Station) costs associated with the MISO and Southwest Power Pool Joint Targeted Interconnection Queue. Entergy Texas estimates that MISO’s proposed cost assignment would result in total charges of approximately $112 million, paid over twenty years beginning in 2031. In May 2026, Entergy Texas filed a protest to the agreement, as well as a separate complaint at the FERC, arguing that the proposed cost allocation is not just and reasonable. In June 2026 the FERC issued a deficiency notice to MISO. In July 2026, MISO and Southwest Power Pool filed answers to the complaint, and MISO filed an answer to the deficiency letter. Protests and comments in response to MISO’s answer to the deficiency letter are due in August 2026.

Public Utilities Disclosure [Text Block]	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 2026, 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 $0.01333 per kWh to $0.01508 per kWh. The primary reason for the rate increase was an under-recovered balance as a result of higher natural gas prices in 2025. Based on circumstances related to ANO 2’s refueling outage, Entergy Arkansas made an adjustment to projected energy costs to phase-in the rate increase gradually. The redetermined rate of $0.01508 per kWh became effective with the first billing cycle in April 2026 through the normal operation of the tariff. Entergy Louisiana As discussed in the Form 10-K, in June 2025 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings (for Entergy Louisiana’s gas operations). The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from January 2023 through June 2025. The LPSC staff issued its audit report in March 2026. The next step is for the LPSC to issue its final report, but there is no deadline or timing requirement associated with the issuance of the final report. In February 2026, Entergy Louisiana, in its monthly filing to update its fuel adjustment clause, requested to defer approximately $141.9 million of fuel costs incurred in January 2026 that were primarily attributable to the effects of Winter Storm Fern, consistent with the LPSC’s general order approved at its February 2026 meeting permitting temporary modifications to the LPSC’s fuel adjustment clause general order. The filing proposed to defer the recovery of these fuel costs over a four-month period from March 2026 through June 2026 to mitigate the customer bill impacts of these fuel costs. In March 2026 the LPSC issued a special order delegating authority to the LPSC executive secretary to review and approve utility-specific requests for deferral of fuel costs from Winter Storm Fern, subject to audit as per the LPSC’s fuel clause general order. In April 2026 the LPSC executive secretary approved Entergy Louisiana’s request for deferral. In April 2026 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2023 through 2025. Discovery is ongoing, and no audit report has been filed. 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 2026 Base Rate Case In February 2026, Entergy Arkansas filed with the APSC a general change in rates, charges, and tariffs. The filing requested a base rate increase to recover a base rate revenue deficiency of $44.6 million and notified the APSC of Entergy Arkansas’s intent to implement a forward test year formula rate plan pursuant to Arkansas legislation passed in 2015. The primary drivers of the revenue deficiency were increased depreciation expense and the impact of net capital additions. Additionally, the filing requested a 9.90% return on common equity and increased depreciation rates as the result of a depreciation study. In March 2026 the APSC issued an order suspending the proposed rates and tariffs filed by Entergy Arkansas. In June 2026 the APSC established a procedural schedule with an evidentiary hearing scheduled to begin in November 2026, and in July 2026 a number of intervenors moved to modify the schedule to conduct additional discovery. Entergy Arkansas opposed the motion in part based on the voluminous discovery conducted to date. 2026 Formula Rate Plan Filing In July 2026, Entergy Arkansas filed with the APSC its 2026 formula rate plan filing to set its formula rate for the 2027 calendar year. The filing contained an evaluation of Entergy Arkansas’s earnings and a netting adjustment for the 2025 historical year. The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2025 historical year was 8.8%, resulting in a $47.2 million formula rate plan revenue increase to produce a 9.65% earned rate of return on common equity. When combined with 2025 historical year formula rate plan revenues of $56.0 million, the total proposed revenue change for the 2025 historical year netting adjustment is a reduction of $8.8 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. Entergy Arkansas’s revenue requirement in this filing did not exceed the constraint. In second quarter 2026, Entergy Arkansas recorded a regulatory liability of $8.8 million to reflect the amount of the 2025 historical year netting adjustment that it collected from customers during the 2025 rate effective period. Generating Arkansas Jobs Act Rider In March 2026, Entergy Arkansas filed its first annual update to the strategic investment recovery rider, requesting recovery of $110.4 million of financing costs during construction of generation and transmission strategic investments related to Ironwood Power Station, Jefferson Power Station, and the Arkansas Cypress Solar facility. The revised rates were requested to be effective with the first billing cycle of June 2026. In April 2026 the APSC general staff filed testimony arguing that the APSC had not issued an order designating Ironwood Power Station as a strategic investment and that related costs should therefore be removed from the annual update. Also in April 2026, Entergy Arkansas filed testimony asserting that the APSC general staff’s position is contrary to the plain language of the statute, which includes an exception for facilities like Ironwood Power Station that were certified by the APSC within a certain timeframe. A hearing was held in April 2026. In June 2026 the APSC approved Entergy Arkansas’s annual update, and rates became effective June 4, 2026. Production Tax Credit Tariffs As discussed in Note 3 to the financial statements in the Form 10-K, in January 2026 the APSC opened a docket to investigate the sale of Entergy Arkansas’s nuclear production tax credits and the appropriate ratemaking treatment of production tax credits for all of Entergy Arkansas’s eligible resources, including how the proceeds of any sales should flow through to customers. For nuclear production tax credits, Entergy Arkansas proposed a nuclear production tax credit rider, which would provide for the immediate flow through to customers of the weighted average cost of capital return on the net proceeds of the monetized nuclear production tax credits. Recognizing that the timing and determination from the IRS is uncertain, the nuclear production tax credit rider also proposes that, if there is an unfavorable IRS determination, Entergy Arkansas would collect applicable costs from customers. As directed by the APSC, in February 2026, Entergy Arkansas submitted a compliance filing to the APSC verifying the status of the solar production tax credits. The filing also verified that the net proceeds from the sale of the nuclear production tax credits were recorded in FERC accounts that are accruing a return for customers’ benefit at a rate that is above the customer deposit rate. Subsequently, in March 2026, Entergy Arkansas filed testimony setting forth its proposal for the solar production tax credits. Specifically, Entergy Arkansas requested the same ratemaking treatment for all of the solar facilities that the APSC already approved for Walnut Bend (i.e., the total net monetized proceeds from production tax credits expected to be generated over the first ten years of a solar facility’s operation are estimated and then amortized over the expected useful life of the asset, which is typically 30 years). Additionally, consistent with prior orders for these resources, the regulatory liabilities associated with the net cash proceeds from monetized solar production tax credits will be included in Entergy Arkansas’s calculation of its weighted average cost of capital providing a return on the unamortized balance for the benefit of customers. Further, Entergy Arkansas proposes to flow the benefits of the solar production tax credits to customers through Entergy Arkansas’s formula rate plan, effective with the formula rate plan rates that will go into effect January 1, 2027. Entergy Arkansas’s proposal would result in the benefits of the production tax credits being passed through to customers, if approved, as reductions in revenue requirement evenly over the life of the assets, rather than only during the 10-year period in which the production tax credits are generated. In April 2026 the APSC general staff filed testimony proposing an amortization period of no more than 15 years for the monetized proceeds for the tax credits associated with the West Memphis Solar and Driver Solar facilities. An evidentiary hearing was held in July 2026, but was not completed. The APSC is to set a date to complete the hearing. Special Rate Contract and Arkansas Cypress Solar As discussed in the Form 10-K, in September 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of the Arkansas Cypress Solar facility, a planned 600 MW solar photovoltaic array with a 350 MW battery energy storage system and associated transmission facilities interconnecting at Entergy Arkansas’s White Bluff substation. The estimated cost of the project is $1,602 million. In March 2026 the APSC approved the Arkansas Cypress Solar facility and Entergy Arkansas’s recovery of the costs of the facility through the Generating Arkansas Jobs Act rider. The APSC also ordered implementation of an independent monitor to oversee costs. In April 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of costs. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including the Arkansas Cypress Solar facility, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates. No alternative recommendations were made by the other parties. The facility is expected to be in service by the end of 2028. Filings with the LPSC (Entergy Louisiana) Retail Rates Resilience Plan Cost Recovery Rider In December 2022, Entergy Louisiana filed an application with the LPSC seeking a public interest finding regarding Phase I of Entergy Louisiana’s Future Ready resilience plan and approval of a rider mechanism to recover the program’s costs. Phase I in the December 2022 application reflected the first five years of a ten-year resilience plan and included investment of approximately $5 billion, including hardening investment, transmission dead-end structures, enhanced vegetation management, and telecommunications improvement. In April 2024 the LPSC approved a framework which includes an initial five-year resilience plan providing for an investment of approximately $1.9 billion with cost recovery via a forward-looking rider with semi-annual true-ups. The plan is subject to specified reporting requirements and includes a performance review of the hardened assets. The LPSC order approving the framework does not include any restrictions on Entergy Louisiana’s ability to file applications for approval of additional investments in resilience. In January 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $40.4 million, or $38.9 million in incremental annual revenues from Entergy Louisiana’s first semi-annual filing in July 2024, for projects expected to be placed in service during the rate-effective period of March 2025 through August 2025. In February 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $50.2 million, or $9.8 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2025 through February 2026. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $5.6 million to be implemented in the January 2026 semi-annual filing. In August 2025 the LPSC staff reviewed the filed rider rates and identified no material issues. In January 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $101.8 million, or $51.6 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of March 2026 through August 2026. Additionally, Entergy Louisiana’s true-up filing included an over-recovery totaling $16.6 million to be implemented in the July 2026 semi-annual filing. In February 2026 the LPSC staff reviewed the filed rider rates and identified no material issues. In July 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $114.2 million, or $12.4 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2026 through February 2027. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $2.5 million to be implemented in the January 2027 semi-annual filing. The LPSC staff is reviewing the filed rider rates. Vegetation Management Rider In November 2025 the LPSC staff issued notice of its initiation of a rulemaking to implement a vegetation management pilot program for LPSC jurisdictional electric utilities. The pilot program would be voluntary and would allow utilities to establish a rider for distribution vegetation management for up to 100% of the utility’s prior calendar year vegetation management spending. The rider may not exceed 1% of a customer’s bill, and the utility would be required to maintain its prior calendar year level of spending on vegetation management as reflected in its base rates or formula rate plan. In February 2026 the LPSC staff filed a report and recommendation along with a proposed final rule providing for the adoption of the pilot program consistent with the terms outlined in the original notice. In March 2026 the LPSC voted to accept the LPSC staff’s recommendation and adopt the proposed pilot program as presented. In April 2026, Entergy Louisiana filed its vegetation management rider for the rate-effective period of May 2026 through December 2026, which included a revenue requirement of $20 million for incremental spending on distribution vegetation management above the prior calendar year level of spending on vegetation management. 2025 Formula Rate Plan Filing In June 2026, Entergy Louisiana filed its formula rate plan evaluation report for its 2025 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 2025, the formula produced an earned return on equity of 9.63%, which falls within the established bandwidth and therefore results in no adjustment to base rider formula rate plan revenue. Additional changes in formula rate plan revenue include: (1) the removal of approximately $73 million in annual customer credits associated with the global stipulated settlement agreement, which have been fully credited to customers in accordance with the agreement; (2) a reduction in customer credits through the tax adjustment mechanism, attributable to the return of Entergy Louisiana’s over-collection of income tax expense associated with Louisiana state tax law changes effective in 2025 and the expiration of certain ad valorem exemptions; (3) increases in transmission and distribution plant in service, as recognized through the transmission and distribution recovery mechanisms, including restoration costs from Winter Storm Fern, for which Entergy Louisiana does not intend to seek relief or exception to the formula rate plan; (4) increases to the additional capacity mechanism; and (5) the final phase-in of additional nuclear depreciation expense, in accordance with the global stipulated settlement agreement. See Note 2 to the financial statements in the Form 10-K for discussion of the global stipulated settlement agreement. Collectively, these factors contributed to a net increase of $222 million in formula rate plan revenue for the period. Subject to LPSC review, the resulting changes from the 2025 formula rate plan evaluation report will become effective for bills rendered during the first billing cycle of September 2026, subject to refund. Request for Extension of Formula Rate Plan In June 2026, Entergy Louisiana submitted a motion requesting the LPSC approve a one-year extension of its current formula rate plan, with all material provisions left unchanged, including the allowed return on common equity of 9.7% with a bandwidth of 40 basis points above and below the midpoint. Entergy Louisiana has requested LPSC action on the proposed extension by August 2026. River Bend Deregulated Asset Plan Filing In September 2025, Entergy Louisiana filed an application seeking LPSC approval to recover from customers, prospectively, approximately $49 million in annual revenues associated with the Louisiana retail deregulated portion of River Bend. Costs associated with the deregulated portion of River Bend have historically been excluded from retail ratemaking as a result of a 1988 LPSC decision. Instead, Entergy Louisiana has been allowed by the LPSC to either recover 4.6 cents per kWh for the power generated from that portion of the plant, or sell the power into the applicable market (subject to certain restrictions). The filing presents evidence that River Bend is a cost-effective and prudent source of needed baseload supply with value to Entergy Louisiana customers and seeks to recover the previously excluded costs, on a prospective basis. In March 2026 the LPSC staff and certain intervenors filed direct testimony recommending that the LPSC deny Entergy Louisiana’s application. The LPSC staff’s testimony further recommends that, if the LPSC were to grant any relief, notwithstanding the LPSC staff’s recommendation, such relief should be limited to allowing only prospective capital additions at River Bend to be included in Entergy Louisiana’s customer rates. Entergy Louisiana’s rebuttal testimony is due in August 2026. A hearing is scheduled for January 2027. Filings with the MPSC (Entergy Mississippi) Retail Rates 2026 Formula Rate Plan Filing In February 2026, Entergy Mississippi submitted its formula rate plan 2026 test year filing and 2025 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2025 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2026 calendar year to also be within the formula rate plan bandwidth. The 2026 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2025 look-back filing compared actual 2025 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 $293 thousand to reflect one outside-the-bandwidth change, a true-up of demand side management costs. In June 2026, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2026 test year filing, with the exception of immaterial adjustments to certain operations and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2026, resulting in no change in formula rate plan revenues for 2026. Pursuant to the stipulation, Entergy Mississippi’s 2025 look-back filing reflected an earned return on rate base of 8.10%, which also resulted in no change in formula rate plan revenues for 2025. In addition, the stipulation included the recovery of the outside-the-bandwidth change discussed above as well as the ratemaking treatment of certain customer contributions, the mechanism for recovery of the benefits of nuclear production tax credits, and the realignment of the first project from the interim facilities rate adjustment to the formula rate plan. In June 2026 the MPSC approved the joint stipulation with rates effective in July 2026. See Note 10 to the financial statements herein for further discussion of the mechanism for recovery of the benefits of nuclear production tax credits included in the joint stipulation. Filings with the City Council (Entergy New Orleans) Retail Rates 2026 Formula Rate Plan Filing In April 2026, Entergy New Orleans submitted to the City Council its formula rate plan 2025 test year filing. The 2025 evaluation report produced an earned return on equity of 7.55% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in an increase in rates of $16.6 million. The increase in rates is driven, in part, by an increase in plant in service, as well as the cost of known and measurable capital additions. The increase is also driven by a decrease in total revenues due to a decline in kWh sales. The filing is subject to a 75-day review and discovery period followed by a 25-day period to resolve any disputes among the parties. In July 2026 the City Council’s advisors issued a report seeking a reduction in Entergy New Orleans’s requested formula rate plan revenues of approximately $4.4 million due to certain proposed cost realignments, imputation of revenues, and disallowances. The City Council’s advisors also recommended that Entergy New Orleans be permitted to collect $20 million over five years beginning in September 2026 to recover amounts that it might be required to pay Entergy Louisiana and Entergy Arkansas pursuant to a FERC order issued in June 2026, relating to an alleged MSS-4 replacement tariff (MSS-4R) violation. However, the FERC order is unclear on its face, and the specific amount of a payment, if any, is unknown. Requests for rehearing and clarification of the FERC order are pending. See “MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding” below for additional discussion of the FERC order. If any rate adjustments are not resolved, the City Council would set a procedural schedule to resolve such disputes. A response by Entergy New Orleans to the advisors’ report is due in August 2026. Resulting rates will be effective with the first billing cycle of September 2026 pursuant to the formula rate plan tariff. Request for Extension of Formula Rate Plan In July 2026, Entergy New Orleans submitted a motion requesting the City Council approve a four-year extension of its current formula rate plan, with all material provisions left unchanged, including the authorized return on equity of 9.35% with a bandwidth of 50 basis points above and below the midpoint. Entergy New Orleans has requested City Council action on the proposed extension by August 2026. Filings with the PUCT and Texas Cities (Entergy Texas) Retail Rates Distribution Cost Recovery Factor (DCRF) Rider In April 2026, 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 $112.5 million annually, or $20.4 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2025 and December 31, 2025. In July 2026 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after July 8, 2026. Transmission Cost Recovery Factor (TCRF) Rider As discussed in the Form 10-K, in October 2025, Entergy Texas filed with the PUCT a request to amend its TCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $30.3 million annually, or $20.6 million in incremental annual revenues beyond Entergy Texas’s then-effective TCRF rider based on its capital invested in transmission between July 1, 2024 and June 30, 2025 and changes in other transmission charges. In April 2026 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 6, 2026. Generation Cost Recovery Rider In March 2026, Entergy Texas filed an application to establish a generation cost recovery rider to begin recovering a return of and on its capital investment in the Orange County Advanced Power Station. The proposed generation cost recovery rider, which includes Entergy Texas’s capital invested in generation for the Orange County Advanced Power Station through December 31, 2025, is designed to collect approximately $150.4 million annually from Entergy Texas’s retail customers. By statute, the proposed generation cost recovery rider rates are to become effective when the Orange County Advanced Power Station is placed into service, which is expected in third quarter 2026. In July 2026 the ALJ with the State Office of Administrative Hearings approved a proposed procedural schedule that includes a hearing on the merits in September 2026 and provides for interim rates to become effective for usage on and after the Orange County Advanced Power Station in-service date, to the extent final rates are not in place by that time. Capacity Cost Recovery Rider (CCRR) In May 2026, Entergy Texas filed with the PUCT a request to establish a new CCRR. The proposed CCRR is designed to collect approximately $58 million annually from Entergy Texas’s retail customers based on Entergy Texas’s eligible capacity-related costs and revenues for the 12 months beginning June 1, 2026. The eligible capacity-related costs and revenues are associated with Entergy Texas’s participation in MISO’s annual planning resource auction. In July 2026 the PUCT approved the CCRR, consistent with Entergy Texas’s as-filed request, and rates became effective on July 10, 2026. Entergy Arkansas Opportunity Sales Proceeding See Note 2 to the financial statements in the Form 10-K for discussion of the Entergy Arkansas opportunity sales proceeding. Complaints Against System Energy See Note 2 to the financial statements in the Form 10-K for information regarding complaints against System Energy and the settlements approved by the FERC that resolved all significant aspects of these complaints. Unit Power Sales Agreement See Note 2 to the financial statements in the Form 10-K for discussion of the Unit Power Sales Agreement. The following is an update to that discussion. Pension Costs Amendment Proceeding As discussed in the Form 10-K, in October 2021, System Energy submitted to the FERC proposed amendments to the Unit Power Sales Agreement to include in rate base the prepaid and accrued pension costs associated with System Energy’s qualified pension plans. In November 2025 the FERC issued an order approving System Energy’s proposed prepaid and accrued pension recovery mechanism. System Energy has been utilizing this methodology in billings since December 1, 2022 and will continue to utilize it going forward. As a result of the FERC’s order, System Energy did not owe any refunds. In December 2025 the APSC filed a request for rehearing of the November 2025 order. In January 2026 the FERC denied the APSC’s rehearing request by operation of law. In May 2026 the FERC issued a follow-up substantive order denying the APSC’s rehearing and sustaining its finding that no refunds are owed. 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-4R net operating loss carryforward proceeding. The following is an update to that discussion. As discussed in the Form 10-K, in October 2021 the LPSC filed a complaint with the FERC alleging that Entergy Services improperly excluded net operating loss carryforward accumulated deferred income taxes (NOLC ADIT) from MSS-4R rates in the period before March 20, 2021. The LPSC argued that sales from Entergy Louisiana to Entergy Texas and Entergy New Orleans were charged at rates lower than they otherwise should have been, and it accordingly seeks surcharges for the period prior to March 20, 2021. The FERC set the complaint for hearing procedures and subsequently the hearing for this complaint proceeding was consolidated with the hearing procedures for Entergy Services’ January 2021 NOLC ADIT filing. Testimony was filed by parties in 2023, and the hearing before a FERC ALJ was concluded in February 2024. In June 2024, the FERC ALJ issued an initial decision addressing three major issues: (1) whether Entergy Services’ proposed prospective inclusion and allocation of NOLC ADIT in MSS-4R rates using a modified with-and-without methodology is just and reasonable; (2) whether Entergy Services correctly calculated excess and deficient accumulated deferred income taxes in accordance with the terms of a prior settlement; and (3) whether NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the January 2021 MSS-4R filing. With respect to issues (1) and (2), the presiding ALJ concluded that Entergy Services’ proposed methodology for allocating and including NOLC ADIT in MSS-4R rates was just and reasonable and that Entergy Services correctly performed the excess and deficient accumulated deferred income taxes calculations. With respect to issue (3), however, the presiding ALJ agreed with the LPSC that NOLC ADIT should have been included in MSS-4R rates since September 1, 2016, and as a result, the presiding ALJ ordered that Entergy Louisiana and Entergy Arkansas recalculate bills for the period of September 1, 2016 through November 11, 2023 with surcharges expected to be due to those operating companies from the purchasing operating companies, Entergy New Orleans, Entergy Texas, and Entergy Louisiana (for some Entergy Arkansas sales). The presiding ALJ also ordered Entergy Services to pay the interest owed to Entergy Louisiana on these surcharges. The surcharge methodology that the presiding ALJ recommended in connection with issue (3) was not supported by any participant in the hearing. As part of their exceptions to the initial decision, all parties to the proceeding opposed the use of the ALJ’s methodology, except for the FERC trial staff, which took no position. During the hearing, the LPSC and the FERC trial staff advocated that the alleged tariff violation should be remedied by the application of Entergy Services’ January 2021 proposed methodology. All other parties, including the PUCT, the City Council, and Entergy Services, opposed any surcharges for the period prior to the March 20, 2021 effective date of the January 2021 filing. Entergy Services disputed the presiding ALJ's rulings on issue (3) and filed exceptions to these rulings in July 2024. In June 2026 the FERC issued its opinion largely affirming the initial decision. Specifically, the FERC found the historic exclusion of NOLC ADIT from MSS-4R rates was a tariff violation and ordered Entergy Louisiana and Entergy Arkansas to provide refunds and/or surcharges, as appropriate, for the period from September 1, 2016 through November 12, 2023 for sales by Entergy Louisiana and for the period December 19, 2013 until May 13, 2024 for sales by Entergy Arkansas. The FERC also ordered the relevant operating company to pay interest on the amounts owed. In July 2026, Entergy Services, along with the LPSC, the City Council, and the PUCT, filed for rehearing and clarification of the FERC’s order. Entergy Services continues to dispute that the NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the tariff amendment filing. Moreover, because of ambiguity in the order and the pending rehearing and clarification requests, it is unclear whether Entergy Arkansas and Entergy Louisiana as sellers will receive surcharges or have to provide refunds. Specifically, there is a lack of clarity as to whether plant-related liability accumulated deferred income taxes must be included in calculating refunds/surcharges. Entergy Services also identified a lack of clarity regarding including the nuclear decommissioning liability deduction in the NOLC ADIT calculation. Depending on the guidance issued by the FERC in response to the request for rehearing and clarification of its June 2026 order, each of the affected Entergy operating companies could either receive material refunds or owe material surcharges. As such, any amounts payable or receivable between the Entergy operating companies that may result from the order are not reasonably estimable as of June 30, 2026. MSS-4 Replacement Tariff – River Bend 70 Depreciation LPSC Complaint In May 2026 the LPSC filed a complaint with the FERC alleging that Entergy Texas owes surcharges to Entergy Louisiana because the depreciation rates used in the MSS-4R for the River Bend 70 sales of capacity and energy were based on a directive of the PUCT for the period from September 1, 2016 to December 31, 2025. The LPSC quantifies the potential surcharge as $100 million, inclusive of interest. Entergy Services disputes that any surcharges are due from Entergy Texas to Entergy Louisiana. In June 2026, Entergy Services filed a motion to dismiss and answer to the complaint submitted by the LPSC. Joint Targeted Interconnection Queue Cost Allocation Dispute In April 2026, MISO submitted to the FERC an unexecuted agreement proposing to assign to Entergy Texas (in its capacity as the owner of the Legend Power Station) costs associated with the MISO and Southwest Power Pool Joint Targeted Interconnection Queue. Entergy Texas estimates that MISO’s proposed cost assignment would result in total charges of approximately $112 million, paid over twenty years beginning in 2031. In May 2026, Entergy Texas filed a protest to the agreement, as well as a separate complaint at the FERC, arguing that the proposed cost allocation is not just and reasonable. In June 2026 the FERC issued a deficiency notice to MISO. In July 2026, MISO and Southwest Power Pool filed answers to the complaint, and MISO filed an answer to the deficiency letter. Protests and comments in response to MISO’s answer to the deficiency letter are due in August 2026.

Fuel and purchased power cost recovery

Entergy Arkansas

Energy Cost Recovery Rider

In March 2026, 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 $0.01333 per kWh to $0.01508 per kWh. The primary reason for the rate increase was an under-recovered balance as a result of higher natural gas prices in 2025. Based on circumstances related to ANO 2’s refueling outage, Entergy Arkansas made an adjustment to projected energy costs to phase-in the rate increase gradually. The redetermined rate of $0.01508 per kWh became effective with the first billing cycle in April 2026 through the normal operation of the tariff.

Entergy Louisiana

As discussed in the Form 10-K, in June 2025 the LPSC staff provided notice of an audit of Entergy Louisiana’s purchased gas adjustment clause filings (for Entergy Louisiana’s gas operations). The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s purchased gas adjustment clause for the period from January 2023 through June 2025. The LPSC staff issued its audit report in March 2026. The next step is for the LPSC to issue its final report, but there is no deadline or timing requirement associated with the issuance of the final report.

In February 2026, Entergy Louisiana, in its monthly filing to update its fuel adjustment clause, requested to defer approximately $141.9 million of fuel costs incurred in January 2026 that were primarily attributable to the effects of Winter Storm Fern, consistent with the LPSC’s general order approved at its February 2026 meeting permitting temporary modifications to the LPSC’s fuel adjustment clause general order. The filing proposed to

defer the recovery of these fuel costs over a four-month period from March 2026 through June 2026 to mitigate the customer bill impacts of these fuel costs. In March 2026 the LPSC issued a special order delegating authority to the LPSC executive secretary to review and approve utility-specific requests for deferral of fuel costs from Winter Storm Fern, subject to audit as per the LPSC’s fuel clause general order. In April 2026 the LPSC executive secretary approved Entergy Louisiana’s request for deferral.

In April 2026 the LPSC staff provided notice of an audit of Entergy Louisiana’s fuel adjustment clause filings. The audit includes a review of the reasonableness of charges flowed through Entergy Louisiana’s fuel adjustment clause for the period from 2023 through 2025. Discovery is ongoing, and no audit report has been filed.

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

2026 Base Rate Case

In February 2026, Entergy Arkansas filed with the APSC a general change in rates, charges, and tariffs. The filing requested a base rate increase to recover a base rate revenue deficiency of $44.6 million and notified the APSC of Entergy Arkansas’s intent to implement a forward test year formula rate plan pursuant to Arkansas legislation passed in 2015. The primary drivers of the revenue deficiency were increased depreciation expense and the impact of net capital additions. Additionally, the filing requested a 9.90% return on common equity and increased depreciation rates as the result of a depreciation study. In March 2026 the APSC issued an order suspending the proposed rates and tariffs filed by Entergy Arkansas. In June 2026 the APSC established a procedural schedule with an evidentiary hearing scheduled to begin in November 2026, and in July 2026 a number of intervenors moved to modify the schedule to conduct additional discovery. Entergy Arkansas opposed the motion in part based on the voluminous discovery conducted to date.

2026 Formula Rate Plan Filing

In July 2026, Entergy Arkansas filed with the APSC its 2026 formula rate plan filing to set its formula rate for the 2027 calendar year. The filing contained an evaluation of Entergy Arkansas’s earnings and a netting adjustment for the 2025 historical year. The filing showed that Entergy Arkansas’s earned rate of return on common equity for the 2025 historical year was 8.8%, resulting in a $47.2 million formula rate plan revenue increase to produce a 9.65% earned rate of return on common equity. When combined with 2025 historical year formula rate plan revenues of $56.0 million, the total proposed revenue change for the 2025 historical year netting adjustment is a reduction of $8.8 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. Entergy Arkansas’s revenue requirement in this filing did not exceed the constraint. In second quarter 2026, Entergy Arkansas recorded a regulatory liability of $8.8 million to reflect the amount of the 2025 historical year netting adjustment that it collected from customers during the 2025 rate effective period.

Generating Arkansas Jobs Act Rider

In March 2026, Entergy Arkansas filed its first annual update to the strategic investment recovery rider, requesting recovery of $110.4 million of financing costs during construction of generation and transmission strategic investments related to Ironwood Power Station, Jefferson Power Station, and the Arkansas Cypress Solar facility. The revised rates were requested to be effective with the first billing cycle of June 2026. In April 2026 the

APSC general staff filed testimony arguing that the APSC had not issued an order designating Ironwood Power Station as a strategic investment and that related costs should therefore be removed from the annual update. Also in April 2026, Entergy Arkansas filed testimony asserting that the APSC general staff’s position is contrary to the plain language of the statute, which includes an exception for facilities like Ironwood Power Station that were certified by the APSC within a certain timeframe. A hearing was held in April 2026. In June 2026 the APSC approved Entergy Arkansas’s annual update, and rates became effective June 4, 2026.

Production Tax Credit Tariffs

As discussed in Note 3 to the financial statements in the Form 10-K, in January 2026 the APSC opened a docket to investigate the sale of Entergy Arkansas’s nuclear production tax credits and the appropriate ratemaking treatment of production tax credits for all of Entergy Arkansas’s eligible resources, including how the proceeds of any sales should flow through to customers. For nuclear production tax credits, Entergy Arkansas proposed a nuclear production tax credit rider, which would provide for the immediate flow through to customers of the weighted average cost of capital return on the net proceeds of the monetized nuclear production tax credits. Recognizing that the timing and determination from the IRS is uncertain, the nuclear production tax credit rider also proposes that, if there is an unfavorable IRS determination, Entergy Arkansas would collect applicable costs from customers. As directed by the APSC, in February 2026, Entergy Arkansas submitted a compliance filing to the APSC verifying the status of the solar production tax credits. The filing also verified that the net proceeds from the sale of the nuclear production tax credits were recorded in FERC accounts that are accruing a return for customers’ benefit at a rate that is above the customer deposit rate. Subsequently, in March 2026, Entergy Arkansas filed testimony setting forth its proposal for the solar production tax credits. Specifically, Entergy Arkansas requested the same ratemaking treatment for all of the solar facilities that the APSC already approved for Walnut Bend (i.e., the total net monetized proceeds from production tax credits expected to be generated over the first ten years of a solar facility’s operation are estimated and then amortized over the expected useful life of the asset, which is typically 30 years). Additionally, consistent with prior orders for these resources, the regulatory liabilities associated with the net cash proceeds from monetized solar production tax credits will be included in Entergy Arkansas’s calculation of its weighted average cost of capital providing a return on the unamortized balance for the benefit of customers. Further, Entergy Arkansas proposes to flow the benefits of the solar production tax credits to customers through Entergy Arkansas’s formula rate plan, effective with the formula rate plan rates that will go into effect January 1, 2027. Entergy Arkansas’s proposal would result in the benefits of the production tax credits being passed through to customers, if approved, as reductions in revenue requirement evenly over the life of the assets, rather than only during the 10-year period in which the production tax credits are generated. In April 2026 the APSC general staff filed testimony proposing an amortization period of no more than 15 years for the monetized proceeds for the tax credits associated with the West Memphis Solar and Driver Solar facilities. An evidentiary hearing was held in July 2026, but was not completed. The APSC is to set a date to complete the hearing.

Special Rate Contract and Arkansas Cypress Solar

As discussed in the Form 10-K, in September 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of the Arkansas Cypress Solar facility, a planned 600 MW solar photovoltaic array with a 350 MW battery energy storage system and associated transmission facilities interconnecting at Entergy Arkansas’s White Bluff substation. The estimated cost of the project is $1,602 million. In March 2026 the APSC approved the Arkansas Cypress Solar facility and Entergy Arkansas’s recovery of the costs of the facility through the Generating Arkansas Jobs Act rider. The APSC also ordered implementation of an independent monitor to oversee costs. In April 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of costs. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including the Arkansas Cypress Solar facility, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates. No alternative recommendations were made by the other parties. The facility is expected to be in service by the end of 2028.

Filings with the LPSC (Entergy Louisiana)

Retail Rates

Resilience Plan Cost Recovery Rider

In December 2022, Entergy Louisiana filed an application with the LPSC seeking a public interest finding regarding Phase I of Entergy Louisiana’s Future Ready resilience plan and approval of a rider mechanism to recover the program’s costs. Phase I in the December 2022 application reflected the first five years of a ten-year resilience plan and included investment of approximately $5 billion, including hardening investment, transmission dead-end structures, enhanced vegetation management, and telecommunications improvement. In April 2024 the LPSC approved a framework which includes an initial five-year resilience plan providing for an investment of approximately $1.9 billion with cost recovery via a forward-looking rider with semi-annual true-ups. The plan is subject to specified reporting requirements and includes a performance review of the hardened assets. The LPSC order approving the framework does not include any restrictions on Entergy Louisiana’s ability to file applications for approval of additional investments in resilience.

In January 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $40.4 million, or $38.9 million in incremental annual revenues from Entergy Louisiana’s first semi-annual filing in July 2024, for projects expected to be placed in service during the rate-effective period of March 2025 through August 2025. In February 2025 the LPSC staff reviewed the filed rider rates and identified no material issues.

In July 2025, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $50.2 million, or $9.8 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2025 through February 2026. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $5.6 million to be implemented in the January 2026 semi-annual filing. In August 2025 the LPSC staff reviewed the filed rider rates and identified no material issues.

In January 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $101.8 million, or $51.6 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of March 2026 through August 2026. Additionally, Entergy Louisiana’s true-up filing included an over-recovery totaling $16.6 million to be implemented in the July 2026 semi-annual filing. In February 2026 the LPSC staff reviewed the filed rider rates and identified no material issues.

In July 2026, Entergy Louisiana’s semi-annual filing sought to collect from Entergy Louisiana’s retail customers approximately $114.2 million, or $12.4 million in incremental annual revenues, for projects expected to be placed in service during the rate-effective period of September 2026 through February 2027. Additionally, Entergy Louisiana’s true-up filing included an under-recovery totaling $2.5 million to be implemented in the January 2027 semi-annual filing. The LPSC staff is reviewing the filed rider rates.

Vegetation Management Rider

In November 2025 the LPSC staff issued notice of its initiation of a rulemaking to implement a vegetation management pilot program for LPSC jurisdictional electric utilities. The pilot program would be voluntary and would allow utilities to establish a rider for distribution vegetation management for up to 100% of the utility’s prior calendar year vegetation management spending. The rider may not exceed 1% of a customer’s bill, and the utility would be required to maintain its prior calendar year level of spending on vegetation management as reflected in its base rates or formula rate plan. In February 2026 the LPSC staff filed a report and recommendation along with a proposed final rule providing for the adoption of the pilot program consistent with the terms outlined in the original notice. In March 2026 the LPSC voted to accept the LPSC staff’s recommendation and adopt the proposed pilot

program as presented. In April 2026, Entergy Louisiana filed its vegetation management rider for the rate-effective period of May 2026 through December 2026, which included a revenue requirement of $20 million for incremental spending on distribution vegetation management above the prior calendar year level of spending on vegetation management.

2025 Formula Rate Plan Filing

In June 2026, Entergy Louisiana filed its formula rate plan evaluation report for its 2025 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 2025, the formula produced an earned return on equity of 9.63%, which falls within the established bandwidth and therefore results in no adjustment to base rider formula rate plan revenue.

Additional changes in formula rate plan revenue include: (1) the removal of approximately $73 million in annual customer credits associated with the global stipulated settlement agreement, which have been fully credited to customers in accordance with the agreement; (2) a reduction in customer credits through the tax adjustment mechanism, attributable to the return of Entergy Louisiana’s over-collection of income tax expense associated with Louisiana state tax law changes effective in 2025 and the expiration of certain ad valorem exemptions; (3) increases in transmission and distribution plant in service, as recognized through the transmission and distribution recovery mechanisms, including restoration costs from Winter Storm Fern, for which Entergy Louisiana does not intend to seek relief or exception to the formula rate plan; (4) increases to the additional capacity mechanism; and (5) the final phase-in of additional nuclear depreciation expense, in accordance with the global stipulated settlement agreement. See Note 2 to the financial statements in the Form 10-K for discussion of the global stipulated settlement agreement. Collectively, these factors contributed to a net increase of $222 million in formula rate plan revenue for the period. Subject to LPSC review, the resulting changes from the 2025 formula rate plan evaluation report will become effective for bills rendered during the first billing cycle of September 2026, subject to refund.

Request for Extension of Formula Rate Plan

In June 2026, Entergy Louisiana submitted a motion requesting the LPSC approve a one-year extension of its current formula rate plan, with all material provisions left unchanged, including the allowed return on common equity of 9.7% with a bandwidth of 40 basis points above and below the midpoint. Entergy Louisiana has requested LPSC action on the proposed extension by August 2026.

River Bend Deregulated Asset Plan Filing

In September 2025, Entergy Louisiana filed an application seeking LPSC approval to recover from customers, prospectively, approximately $49 million in annual revenues associated with the Louisiana retail deregulated portion of River Bend. Costs associated with the deregulated portion of River Bend have historically been excluded from retail ratemaking as a result of a 1988 LPSC decision. Instead, Entergy Louisiana has been allowed by the LPSC to either recover 4.6 cents per kWh for the power generated from that portion of the plant, or sell the power into the applicable market (subject to certain restrictions). The filing presents evidence that River Bend is a cost-effective and prudent source of needed baseload supply with value to Entergy Louisiana customers and seeks to recover the previously excluded costs, on a prospective basis. In March 2026 the LPSC staff and certain intervenors filed direct testimony recommending that the LPSC deny Entergy Louisiana’s application. The LPSC staff’s testimony further recommends that, if the LPSC were to grant any relief, notwithstanding the LPSC staff’s recommendation, such relief should be limited to allowing only prospective capital additions at River Bend to be included in Entergy Louisiana’s customer rates. Entergy Louisiana’s rebuttal testimony is due in August 2026. A hearing is scheduled for January 2027.

Filings with the MPSC (Entergy Mississippi)

Retail Rates

2026 Formula Rate Plan Filing

In February 2026, Entergy Mississippi submitted its formula rate plan 2026 test year filing and 2025 look-back filing showing Entergy Mississippi’s earned return on rate base for the historical 2025 calendar year to be within the formula rate plan bandwidth and projected earned return for the 2026 calendar year to also be within the formula rate plan bandwidth. The 2026 test year filing resulted in an earned return on rate base of 7.64% and reflected no change in formula rate plan revenues. The 2025 look-back filing compared actual 2025 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 $293 thousand to reflect one outside-the-bandwidth change, a true-up of demand side management costs.

In June 2026, Entergy Mississippi and the Mississippi Public Utilities Staff entered into a joint stipulation that confirmed the 2026 test year filing, with the exception of immaterial adjustments to certain operations and maintenance expenses. The formula rate plan reflected an earned return on rate base of 7.68% for calendar year 2026, resulting in no change in formula rate plan revenues for 2026. Pursuant to the stipulation, Entergy Mississippi’s 2025 look-back filing reflected an earned return on rate base of 8.10%, which also resulted in no change in formula rate plan revenues for 2025. In addition, the stipulation included the recovery of the outside-the-bandwidth change discussed above as well as the ratemaking treatment of certain customer contributions, the mechanism for recovery of the benefits of nuclear production tax credits, and the realignment of the first project from the interim facilities rate adjustment to the formula rate plan. In June 2026 the MPSC approved the joint stipulation with rates effective in July 2026. See Note 10 to the financial statements herein for further discussion of the mechanism for recovery of the benefits of nuclear production tax credits included in the joint stipulation.

Filings with the City Council (Entergy New Orleans)

Retail Rates

2026 Formula Rate Plan Filing

In April 2026, Entergy New Orleans submitted to the City Council its formula rate plan 2025 test year filing. The 2025 evaluation report produced an earned return on equity of 7.55% compared to the authorized return on equity of 9.35%. Without adjustments, this would result in an increase in rates of $16.6 million. The increase in rates is driven, in part, by an increase in plant in service, as well as the cost of known and measurable capital additions. The increase is also driven by a decrease in total revenues due to a decline in kWh sales. The filing is subject to a 75-day review and discovery period followed by a 25-day period to resolve any disputes among the parties.

In July 2026 the City Council’s advisors issued a report seeking a reduction in Entergy New Orleans’s requested formula rate plan revenues of approximately $4.4 million due to certain proposed cost realignments, imputation of revenues, and disallowances. The City Council’s advisors also recommended that Entergy New Orleans be permitted to collect $20 million over five years beginning in September 2026 to recover amounts that it might be required to pay Entergy Louisiana and Entergy Arkansas pursuant to a FERC order issued in June 2026, relating to an alleged MSS-4 replacement tariff (MSS-4R) violation. However, the FERC order is unclear on its face, and the specific amount of a payment, if any, is unknown. Requests for rehearing and clarification of the FERC order are pending. See “MSS-4 Replacement Tariff - Net Operating Loss Carryforward Proceeding” below for additional discussion of the FERC order. If any rate adjustments are not resolved, the City Council would set a procedural schedule to resolve such disputes. A response by Entergy New Orleans to the advisors’ report is

due in August 2026. Resulting rates will be effective with the first billing cycle of September 2026 pursuant to the formula rate plan tariff.

Request for Extension of Formula Rate Plan

In July 2026, Entergy New Orleans submitted a motion requesting the City Council approve a four-year extension of its current formula rate plan, with all material provisions left unchanged, including the authorized return on equity of 9.35% with a bandwidth of 50 basis points above and below the midpoint. Entergy New Orleans has requested City Council action on the proposed extension by August 2026.

Filings with the PUCT and Texas Cities (Entergy Texas)

Retail Rates

Distribution Cost Recovery Factor (DCRF) Rider

In April 2026, 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 $112.5 million annually, or $20.4 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2025 and December 31, 2025. In July 2026 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after July 8, 2026.

Transmission Cost Recovery Factor (TCRF) Rider

As discussed in the Form 10-K, in October 2025, Entergy Texas filed with the PUCT a request to amend its TCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $30.3 million annually, or $20.6 million in incremental annual revenues beyond Entergy Texas’s then-effective TCRF rider based on its capital invested in transmission between July 1, 2024 and June 30, 2025 and changes in other transmission charges. In April 2026 the PUCT approved the TCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective for usage on and after April 6, 2026.

Generation Cost Recovery Rider

In March 2026, Entergy Texas filed an application to establish a generation cost recovery rider to begin recovering a return of and on its capital investment in the Orange County Advanced Power Station. The proposed generation cost recovery rider, which includes Entergy Texas’s capital invested in generation for the Orange County Advanced Power Station through December 31, 2025, is designed to collect approximately $150.4 million annually from Entergy Texas’s retail customers. By statute, the proposed generation cost recovery rider rates are to become effective when the Orange County Advanced Power Station is placed into service, which is expected in third quarter 2026. In July 2026 the ALJ with the State Office of Administrative Hearings approved a proposed procedural schedule that includes a hearing on the merits in September 2026 and provides for interim rates to become effective for usage on and after the Orange County Advanced Power Station in-service date, to the extent final rates are not in place by that time.

Capacity Cost Recovery Rider (CCRR)

In May 2026, Entergy Texas filed with the PUCT a request to establish a new CCRR. The proposed CCRR is designed to collect approximately $58 million annually from Entergy Texas’s retail customers based on Entergy Texas’s eligible capacity-related costs and revenues for the 12 months beginning June 1, 2026. The eligible capacity-related costs and revenues are associated with Entergy Texas’s participation in MISO’s annual planning

resource auction. In July 2026 the PUCT approved the CCRR, consistent with Entergy Texas’s as-filed request, and rates became effective on July 10, 2026.

Complaints Against System Energy

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

Unit Power Sales Agreement

See Note 2 to the financial statements in the Form 10-K for discussion of the Unit Power Sales Agreement. The following is an update to that discussion.

Pension Costs Amendment Proceeding

As discussed in the Form 10-K, in October 2021, System Energy submitted to the FERC proposed amendments to the Unit Power Sales Agreement to include in rate base the prepaid and accrued pension costs associated with System Energy’s qualified pension plans. In November 2025 the FERC issued an order approving System Energy’s proposed prepaid and accrued pension recovery mechanism. System Energy has been utilizing this methodology in billings since December 1, 2022 and will continue to utilize it going forward. As a result of the FERC’s order, System Energy did not owe any refunds. In December 2025 the APSC filed a request for rehearing of the November 2025 order. In January 2026 the FERC denied the APSC’s rehearing request by operation of law. In May 2026 the FERC issued a follow-up substantive order denying the APSC’s rehearing and sustaining its finding that no refunds are owed.

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-4R net operating loss carryforward proceeding. The following is an update to that discussion.

As discussed in the Form 10-K, in October 2021 the LPSC filed a complaint with the FERC alleging that Entergy Services improperly excluded net operating loss carryforward accumulated deferred income taxes (NOLC ADIT) from MSS-4R rates in the period before March 20, 2021. The LPSC argued that sales from Entergy Louisiana to Entergy Texas and Entergy New Orleans were charged at rates lower than they otherwise should have been, and it accordingly seeks surcharges for the period prior to March 20, 2021. The FERC set the complaint for hearing procedures and subsequently the hearing for this complaint proceeding was consolidated with the hearing procedures for Entergy Services’ January 2021 NOLC ADIT filing.

Testimony was filed by parties in 2023, and the hearing before a FERC ALJ was concluded in February 2024. In June 2024, the FERC ALJ issued an initial decision addressing three major issues: (1) whether Entergy Services’ proposed prospective inclusion and allocation of NOLC ADIT in MSS-4R rates using a modified with-and-without methodology is just and reasonable; (2) whether Entergy Services correctly calculated excess and deficient accumulated deferred income taxes in accordance with the terms of a prior settlement; and (3) whether NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the January 2021 MSS-4R filing.

With respect to issues (1) and (2), the presiding ALJ concluded that Entergy Services’ proposed methodology for allocating and including NOLC ADIT in MSS-4R rates was just and reasonable and that Entergy Services correctly performed the excess and deficient accumulated deferred income taxes calculations. With respect to issue (3), however, the presiding ALJ agreed with the LPSC that NOLC ADIT should have been included in MSS-4R rates since September 1, 2016, and as a result, the presiding ALJ ordered that Entergy Louisiana and Entergy Arkansas recalculate bills for the period of September 1, 2016 through November 11, 2023 with surcharges expected to be due to those operating companies from the purchasing operating companies, Entergy New Orleans, Entergy Texas, and Entergy Louisiana (for some Entergy Arkansas sales). The presiding ALJ also ordered Entergy Services to pay the interest owed to Entergy Louisiana on these surcharges.

The surcharge methodology that the presiding ALJ recommended in connection with issue (3) was not supported by any participant in the hearing. As part of their exceptions to the initial decision, all parties to the proceeding opposed the use of the ALJ’s methodology, except for the FERC trial staff, which took no position. During the hearing, the LPSC and the FERC trial staff advocated that the alleged tariff violation should be remedied by the application of Entergy Services’ January 2021 proposed methodology. All other parties, including the PUCT, the City Council, and Entergy Services, opposed any surcharges for the period prior to the March 20, 2021 effective date of the January 2021 filing.

Entergy Services disputed the presiding ALJ's rulings on issue (3) and filed exceptions to these rulings in July 2024. In June 2026 the FERC issued its opinion largely affirming the initial decision. Specifically, the FERC found the historic exclusion of NOLC ADIT from MSS-4R rates was a tariff violation and ordered Entergy Louisiana and Entergy Arkansas to provide refunds and/or surcharges, as appropriate, for the period from September 1, 2016 through November 12, 2023 for sales by Entergy Louisiana and for the period December 19, 2013 until May 13, 2024 for sales by Entergy Arkansas. The FERC also ordered the relevant operating company to pay interest on the amounts owed.

In July 2026, Entergy Services, along with the LPSC, the City Council, and the PUCT, filed for rehearing and clarification of the FERC’s order. Entergy Services continues to dispute that the NOLC ADIT should have been included in MSS-4R rates prior to the effective date of the tariff amendment filing. Moreover, because of ambiguity in the order and the pending rehearing and clarification requests, it is unclear whether Entergy Arkansas and Entergy Louisiana as sellers will receive surcharges or have to provide refunds. Specifically, there is a lack of clarity as to whether plant-related liability accumulated deferred income taxes must be included in calculating refunds/surcharges. Entergy Services also identified a lack of clarity regarding including the nuclear decommissioning liability deduction in the NOLC ADIT calculation. Depending on the guidance issued by the FERC in response to the request for rehearing and clarification of its June 2026 order, each of the affected Entergy operating companies could either receive material refunds or owe material surcharges. As such, any amounts payable or receivable between the Entergy operating companies that may result from the order are not reasonably estimable as of June 30, 2026.

MSS-4 Replacement Tariff – River Bend 70 Depreciation LPSC Complaint

In May 2026 the LPSC filed a complaint with the FERC alleging that Entergy Texas owes surcharges to Entergy Louisiana because the depreciation rates used in the MSS-4R for the River Bend 70 sales of capacity and energy were based on a directive of the PUCT for the period from September 1, 2016 to December 31, 2025. The LPSC quantifies the potential surcharge as $100 million, inclusive of interest. Entergy Services disputes that any surcharges are due from Entergy Texas to Entergy Louisiana. In June 2026, Entergy Services filed a motion to dismiss and answer to the complaint submitted by the LPSC.

Joint Targeted Interconnection Queue Cost Allocation Dispute

In April 2026, MISO submitted to the FERC an unexecuted agreement proposing to assign to Entergy Texas (in its capacity as the owner of the Legend Power Station) costs associated with the MISO and Southwest

Power Pool Joint Targeted Interconnection Queue. Entergy Texas estimates that MISO’s proposed cost assignment would result in total charges of approximately $112 million, paid over twenty years beginning in 2031. In May 2026, Entergy Texas filed a protest to the agreement, as well as a separate complaint at the FERC, arguing that the proposed cost allocation is not just and reasonable. In June 2026 the FERC issued a deficiency notice to MISO. In July 2026, MISO and Southwest Power Pool filed answers to the complaint, and MISO filed an answer to the deficiency letter. Protests and comments in response to MISO’s answer to the deficiency letter are due in August 2026.
