Entergy operates primarily through a single reportable segment, Utility. The Utility segment includes the generation, transmission, distribution, and sale of electric power in portions of Arkansas, Mississippi, Texas, and Louisiana, including the City of New Orleans; and included operation of a small natural gas distribution business in portions of Louisiana through June 30, 2025. See Note 14 to the financial statements in the Form 10-K for discussion of the sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses on July 1, 2025. See Note 7 to the financial statements herein for discussion of and financial information regarding Entergy’s reportable segment.

In January 2026, portions of Entergy’s service territory experienced the effects of Winter Storm Fern, including prolonged freezing temperatures, heavy ice accumulations, and wind, which caused severe damage to Entergy’s infrastructure. Entergy’s current estimate for the cost of mobilizing crews and restoring power is approximately $480 million, including approximately $400 million in capital costs and approximately $80 million in non-capital costs. The impacts were primarily at Entergy Louisiana and Entergy Mississippi. There are well-established mechanisms and precedent for addressing these catastrophic events and providing the process for regulatory review of storm costs for prudence and for recovery of prudently incurred storm costs in accordance with applicable regulatory and legal principles.

The severe weather event also affected the market for natural gas due to the effects of severe cold on the gas supply system and increased demand for gas to support electricity loads. Natural gas purchases in January 2026 for Entergy were $483 million, including $74 million for Entergy Arkansas, $256 million for Entergy Louisiana, $85 million for Entergy Mississippi, $20 million for Entergy New Orleans, and $48 million for Entergy Texas. This compares to natural gas purchases in January 2025 for Entergy of $207 million, including $25 million for Entergy Arkansas, $115 million for Entergy Louisiana, $28 million for Entergy Mississippi, $4 million for Entergy New Orleans, and $35 million for Entergy Texas. The Utility operating companies each have fuel recovery mechanisms in place to recover their natural gas costs. With the potential effect of the higher natural gas costs on customers, the Utility operating companies plan to work with their retail regulators to recover these costs in a manner that mitigates the effects on customer bills. See Note 2 to the financial statements herein and in the Form 10-K for a discussion of fuel cost recovery at the Utility operating companies.

First Quarter 2026 Compared to First Quarter 2025

Following are income statement variances for Utility, Parent & Other, and Entergy comparing the first quarter 2026 to the first quarter 2025 showing how much the line item increased or (decreased) in comparison to the prior period.

(a)Parent & Other includes eliminations, which are primarily intersegment activity.

Utility

The Utility operating companies’ results include revenues from rate mechanisms designed to recover fuel, purchased power, and other costs such that the revenues and expenses associated with these items generally offset and do not affect net income. “Fuel, rider, and other revenues that do not significantly affect net income” includes the revenue variance associated with these items.

The retail electric price variance is primarily due to:

•an increase in Entergy Arkansas’s formula rate plan rates effective January 2026;

•increases in Entergy Louisiana’s resilience plan cost recovery rider effective March 2025 and March 2026;

•an increase in Entergy Mississippi’s formula rate plan rates resulting from an increase in interim facilities rate adjustment revenues effective January 2026; and

•increases in Entergy Texas’s distribution cost recovery factor rider effective June 2025 and December 2025.

See Note 2 to the financial statements herein and in the Form 10-K for discussion of the regulatory proceedings discussed above.

The return on construction work in progress for certain utility plant investments variance represents the revenue related to the amortization of certain customer advances designed to provide a return on investment in construction work in progress for certain utility plant investments, which is recognized as the related costs are incurred.

The volume/weather variance is primarily due to the effect of less favorable weather on residential sales, substantially offset by an increase in industrial usage. The increase in industrial usage is primarily due to an increase in demand from large industrial customers, primarily in the data center, primary metals, and transportation industries.

The effect of sale of natural gas distribution businesses variance represents the decrease in operating revenues resulting from the absence of natural gas revenues at Entergy Louisiana and Entergy New Orleans following the sale of the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses on July 1, 2025. The decrease in natural gas operating revenues is substantially offset in net income by the absence of operating expenses related to the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses following the sale. See Note 14 to the financial statements in the Form 10-K for discussion of the sale of the Entergy Louisiana and Entergy New Orleans natural gas distribution businesses on July 1, 2025.

Total electric energy sales for Utility for the three months ended March 31, 2026 and 2025 are as follows:

See Note 12 to the financial statements herein for additional discussion of operating revenues.

Other Income Statement Items

Utility

Other operation and maintenance expenses decreased slightly comparing the first quarter 2026 to the first quarter 2025 primarily due to a decrease of $17 million in insurance expenses primarily due to higher nuclear insurance refunds and a decrease of $12 million in loss provisions. The decrease was substantially offset by an increase of $13 million in power delivery expenses primarily due to increased contract labor costs and an increase of $11 million in compensation and benefits costs primarily due to a revision to estimated incentive-based compensation expense in first quarter 2025.

Depreciation and amortization expenses increased primarily due to additions to plant in service, an increase in FERC jurisdictional depreciation rates at Entergy Arkansas and Entergy Louisiana effective January 2026, and an increase in nuclear depreciation rates at Entergy Louisiana effective September 2025 in accordance with the global stipulated settlement agreement approved by the LPSC in August 2024. See Note 2 to the financial statements in the Form 10-K for discussion of the Entergy Louisiana global stipulated settlement agreement.

Entergy records a regulatory charge or credit for the difference between asset retirement obligation-related expenses and nuclear decommissioning trust earnings plus asset retirement obligation-related costs collected in revenue.

Other income increased primarily due to changes in decommissioning trust fund activity, including portfolio rebalancing of decommissioning trust funds in first quarter 2026.

•the issuance by Entergy Arkansas of $300 million of 5.45% Series mortgage bonds in May 2025;

•the issuances by Entergy Arkansas of $500 million of 5.75% Series mortgage bonds and $500 million of 4.95% Series mortgage bonds, each in January 2026;

•the issuances by Entergy Louisiana of $750 million of 5.65% Series mortgage bonds and $750 million of 4.90% Series mortgage bonds, each in February 2026;

•the issuance by Entergy Mississippi of $600 million of 5.80% Series mortgage bonds in March 2025;

•the issuance by Entergy Texas of $500 million of 5.25% Series mortgage bonds in February 2025;

•an increase of $8 million in carrying costs on customer advances, including customer advances for construction; and

•$8 million in carrying costs in first quarter 2026 on retained net proceeds from the monetization of nuclear production tax credits.

The increase was partially offset by the repayment by Entergy Louisiana of $250 million of 4.44% Series mortgage bonds in January 2026.

Parent and Other

Asset write-offs, impairments, and related charges includes an $18 million non-cash impairment charge recognized in first quarter 2026 related to the sale of the non-utility operations businesses’ interest in the Independence power plant in April 2026.

Interest expense increased primarily due to the issuances of junior subordinated debentures totaling $1.3 billion in November 2025.

The effective income tax rate was 18.3% for the first quarter 2026. The difference in the effective income tax rate for the first quarter 2026 versus the federal statutory rate of 21% was primarily due tothe amortization of excess accumulated deferred income taxes, certain book and tax differences related to utility plant items, and book and tax differences related to the allowance for equity funds used during construction, partially offset by the accrual for state income taxes.

The effective income tax rate was 21.6% for the first quarter 2025. The difference in the effective income tax rate for the first quarter 2025 versus the federal statutory rate of 21% was primarily due to the accrual for state income taxes, partially offset by certain book and tax differences related to utility plant items and book and tax differences related to the allowance for equity funds used during construction.

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS - Liquidity and Capital Resources” in the Form 10-K for a discussion of Entergy’s capital structure, capital spending plans and other uses of capital, and sources of capital.

Capital Structure and Resources

Entergy’s debt to capital ratio is shown in the following table. The increase in the debt to capital ratio for Entergy Corporation is primarily due to the net issuance of long-term debt in 2026.

(a)Calculation excludes the Texas securitization bonds, which are non-recourse to Entergy Texas.

As of March 31, 2026, 20.7% of the debt outstanding is at the parent company, Entergy Corporation, and 79.3% is at the Utility segment. Net debt consists of debt less cash and cash equivalents. Debt consists of notes payable and commercial paper, finance lease obligations, and long-term debt, including the currently maturing portion. Capital consists of debt, equity, and subsidiaries’ preferred stock without sinking fund. Net capital consists of capital less cash and cash equivalents. The debt to capital ratio excluding securitization bonds and net debt to net capital ratio excluding securitization bonds are non-GAAP measures. Entergy uses the debt to capital ratios excluding securitization bonds in analyzing its financial condition and believes they provide useful information to its investors and creditors in evaluating Entergy’s financial condition because the securitization bonds are non-recourse to Entergy, as more fully described in Note 5 to the financial statements in the Form 10-K. Entergy also uses the net debt to net capital ratio excluding securitization bonds in analyzing its financial condition and believes it provides useful information to its investors and creditors in evaluating Entergy’s financial condition because net debt indicates Entergy’s outstanding debt position that could not be readily satisfied by cash and cash equivalents on hand.

Entergy Corporation has in place a credit facility that has a borrowing capacity of $3 billion and expires in June 2030. The facility includes fronting commitments for the issuance of letters of credit against $20 million of the total borrowing capacity of the credit facility. The commitment fee is currently 0.225% of the undrawn commitment amount. Commitment fees and interest rates on loans under the credit facility can fluctuate depending on the senior unsecured debt ratings of Entergy Corporation. Although there were no borrowings under the facility for the three months ended March 31, 2026, the estimated interest rate as of March 31, 2026 that would have been applied to outstanding borrowings under the facility was 5.27%. The following is a summary of the amounts outstanding and capacity available under the credit facility as of March 31, 2026:

Entergy Corporation’s credit facility includes a covenant requiring Entergy to maintain a consolidated debt ratio, as defined, of 65% or less of its total capitalization. The calculation of this debt ratio under Entergy Corporation’s credit facility is different than the calculation of the debt to capital ratio above. Entergy is currently in compliance with the covenant and expects to remain in compliance with this covenant. If Entergy fails to meet this ratio, or if Entergy Corporation or one of the Registrant Subsidiaries (except Entergy New Orleans and System Energy) defaults on other indebtedness or is in bankruptcy or insolvency proceedings, an acceleration of the Entergy Corporation credit facility’s maturity date may occur. See Note 4 to the financial statements herein for additional discussion of the Entergy Corporation credit facility and discussion of the Registrant Subsidiaries’ credit facilities.

Entergy Corporation has a commercial paper program with a Board-approved program limit of $2 billion. As of March 31, 2026, Entergy Corporation had $1,367 million of commercial paper outstanding. The weighted-average interest rate for the three months ended March 31, 2026 was 3.95%.

As discussed in the Form 10-K, Entergy’s sources to meet its capital requirements and to fund potential investments include, among other things, debt and equity issuances in the capital markets. In addition to other planned debt issuances by the Registrant Subsidiaries and Entergy Corporation, borrowings under new or existing credit facilities and Entergy Corporation’s commercial paper program, and the planned equity issuances discussed below, Entergy Corporation currently expects to issue $3 billion in junior subordinated debentures through 2029.

Equity Issuances and Equity Distribution Program

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS - Liquidity and Capital Resources - Sources of Capital - Equity Issuances and Equity Distribution Program” in the Form 10-K and Note 3 to the financial statements herein for discussion of equity issuances, the equity distribution program, and equity forward sale agreements. The following are updates to that discussion.

In February 2026, Entergy Corporation physically settled a portion of its obligations under certain of its then-outstanding forward sale agreements under its at the market equity distribution program for cash proceeds of $346 million.

Entergy Corporation currently expects to issue approximately $6.6 billion of equity through 2029, which it may issue under its at the market equity distribution program or otherwise, with approximately $1.9 billion already settled or contracted under forward sale agreements as of March 31, 2026. See Note 3 to the financial statements herein and Note 7 to the financial statements in the Form 10-K for discussion of the forward sale agreements.

Capital Expenditure Plans and Other Uses of Capital

See the table and discussion in the Form 10-K under “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS - Liquidity and Capital Resources - Capital Expenditure Plans and Other Uses of Capital,” that sets forth the amounts of Entergy’s planned construction and other capital investments for 2026 through 2029. The following are updates to that discussion.

Following are the current annual amounts of Entergy’s planned construction and other capital investments.

The updated capital plan for 2026-2029 reflects incremental capital investments for potential generation projects, primarily related to resources identified in Entergy Louisiana’s application filed with the LPSC in March 2026 as discussed below in “Entergy Louisiana Additional Generation and Transmission Resources”. The capital plan includes amounts Entergy plans to spend on routine capital projects that are necessary to support reliability of its service, equipment, or systems and to support normal customer growth. In addition to routine capital projects, the capital plan also includes amounts Entergy plans to spend on non-routine capital investments for which Entergy is either contractually obligated, has Board approval, or otherwise expects to make to satisfy regulatory or legal requirements. Amounts include the following types of construction and capital investments:

•investments in generation projects to modernize, decarbonize, expand, and diversify the Utility operating companies’ portfolios, as well as to support customer growth, including Ironwood Power Station, Jefferson Power Station, Arkansas Cypress Solar, Segno Solar, Votaw Solar, Bogalusa West Solar, Cypress Harvest Solar, Franklin Farms Power Station Units 1 and 2, Waterford 5 Power Station, Cottonwood Power Station, Westlake Power Station, Richland Parish Units 1-4, Pointe Coupee Units 1-3, Delta Blues Advanced Power Station, Delta Solar, Penton Solar, Traceview Advanced Power Station, Vicksburg Advanced Power Station, Orange County Advanced Power Station, Lone Star Power Station, Legend Power Station, and potential construction of additional generation;

•investments in the Utility nuclear fleet;

•transmission spending to improve reliability and resilience while also supporting renewables expansion and customer growth; and

•distribution and Utility support spending to improve reliability, resilience, and customer experience through projects focused on asset renewals and enhancements and grid stability.

The planned construction and capital investments amounts above exclude investments expected to be funded with customer advances for construction.

Renewables

Entergy Arkansas 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. The facility is expected to be in service by the end of 2028.

Cypress Harvest Solar

As discussed in the Form 10-K, in February 2026, Entergy Louisiana filed an application seeking LPSC approval and certification for the Cypress Harvest Solar facility, a 200 MW solar facility to be located in Iberville Parish, Louisiana. In March 2026 the LPSC staff filed an affidavit attesting that the Cypress Harvest Solar Facility meets the applicable parameters for Entergy Louisiana’s expedited certification process and recommending that the LPSC grant certification. At its April 2026 meeting, the LPSC voted to grant the requested approval and certification. The facility is expected to be in service by 2028.

Other Generation and Transmission

Jefferson Power Station

As discussed in the Form 10-K, in August 2025, Entergy Arkansas filed an application with the APSC seeking a certificate of environmental compatibility and public need for the construction and operation of Jefferson Power Station, an approximately 754 MW natural gas-fired combined cycle combustion turbine facility to be located in Jefferson County, Arkansas. The estimated cost of the project is $1,602 million. In January 2026 the APSC issued its order finding that Entergy Arkansas had demonstrated a need for the resource but had not met its burden with respect to supporting the prudence of the costs to construct the resource. The APSC acknowledged that the costs would be greater if Entergy Arkansas waited to pursue the resource. The APSC authorized Entergy Arkansas to proceed with Jefferson Power Station as a strategic investment with estimated costs set at a benchmark, which the APSC erroneously believed reflected the current cost estimate but was, in fact, $90 million below the cost presented. In its January 2026 order, the APSC also approved Entergy Arkansas’s recovery of the costs of constructing Jefferson Power Station through the Generating Arkansas Jobs Act rider. Additionally, in its January 2026 order, the APSC found that Entergy Arkansas should conduct all-source competitive solicitations for future generation additions, with limited exceptions where Entergy Arkansas believes that a specific solicitation should be restricted to a certain resource and provides a detailed explanation to the APSC supporting this belief, which the APSC later confirmed in its March 2026 order that this is a narrow exception. In February 2026, Entergy Arkansas filed for rehearing seeking to correct the benchmark. In March 2026 the APSC issued an order denying Entergy Arkansas’s petition and maintained the benchmark, although costs over the benchmark were not found to be disallowed. Also in its March 2026 order, the APSC ordered Entergy Arkansas to submit a draft of an all-source request for proposals within thirty days of the order, which Entergy Arkansas filed in April 2026. Also in March 2026, Entergy Arkansas filed with the APSC its proposal for an independent monitor to oversee the reasonableness of its construction costs, as required by the APSC order. In April 2026 the APSC issued an order consolidating Entergy Arkansas’s cost independent monitor proposals for three pending resources, including Jefferson Power Station, into a single docket and directing parties with full intervention status to respond to the proposals and recommend independent monitor candidates.

Entergy Louisiana Additional Generation and Transmission Resources

See the Form 10-K for discussion of Entergy Louisiana’s October 2024 application with the LPSC seeking approval of a variety of generation and transmission resources proposed in connection with establishing service to a new data center to be developed by a subsidiary of Meta Platforms, Inc. in north Louisiana, for which an electric service agreement was previously executed.

In March 2026, Entergy Louisiana entered into an electric service agreement with Evest LLC (Evest), a subsidiary of Meta Platforms, Inc., in connection with establishing service to a second new data center to be developed by Evest in north Louisiana. The obligations pursuant to the agreement will commence following construction of certain transmission facilities needed to serve Evest, and the effectiveness of the agreement is conditioned upon receipt of required governmental approvals, including approval from the LPSC. Also in March 2026, Entergy Louisiana filed an application with the LPSC for certification to construct seven new combined cycle combustion turbine generation resources totaling 5,278 MW at a total cost of approximately $12.9 billion, each of which will be enabled for future carbon capture and storage, and three battery energy storage systems, including two that will be co-located with solar resources at the Cypress Harvest Solar Facility in Iberville Parish and the Bogalusa West Solar Facility in Washington Parish. The application also seeks approval to construct a new 500 kV transmission line, from West Fork Creek to St. Landry, estimated to cost $1.4 billion, and other related transmission facilities. Four of the new combined cycle combustion turbine generation resources are to be located near the customer site in north Louisiana (Richland Parish Units 1-4), while the remaining three units will be located near the existing Big Cajun site in Pointe Coupee Parish (Pointe Coupee Units 1-3). The seven new combined cycle combustion turbine generation resources have various estimated in-service dates in 2030 and 2031. The application also requests certain approvals related to a corporate sustainability agreement with the new customer. The corporate sustainability agreement contemplates the new customer contributing to the costs of the future addition of 2,500 MW of new renewable and energy storage resources, agreements involving nuclear-related efforts and contributions to bill assistance and other programs for low-income residents. Entergy Louisiana anticipates recovering the incremental cost to serve the customer through direct financial contributions from the customer and the revenues it expects to earn under the electric service agreement. The application is pending before the LPSC. At its April 2026 meeting, the LPSC voted to direct the administrative hearings division to adopt a procedural schedule that would allow for LPSC consideration of the matter at its December 2026 meeting, and also to have the administrative hearings division serve as a hearing examiner and compile a record for the LPSC to consider without the issuance of a formal recommendation from the ALJ.

The electric service agreement and related contracts contain provisions that protect Entergy Louisiana’s current customers in a manner consistent with the LPSC’s Lightning Initiative and Entergy Louisiana’s Fair Share Plus guidelines, which the LPSC and Entergy Louisiana, respectively, developed in response to increased investment in large data centers in Louisiana. The protections include terms requiring the customer to pay Entergy Louisiana’s incremental costs to serve the customer, including through contributions in aid of construction, other advanced payments and minimum monthly bills. The agreements also include specified financial obligations in the event that Evest terminates the contracts early, restructures the project, or in the event of default. These specified financial obligations would be based on Entergy Louisiana’s unrecovered incremental costs to serve Evest at the time of such an event. Evest’s obligations under the electric service agreement and related contracts are secured by various forms of collateral, including a guaranty from Meta Platforms, Inc.

Finally, the electric service agreement also includes provisions relating to Entergy Louisiana’s performance obligations, including the timely construction of the facilities supporting service to Evest, audit rights for the construction costs supported by Evest, and service standards during the term of the electric service agreement. Entergy Louisiana’s failure to meet one or more of these performance obligations could result in specified financial and/or non-financial penalties. Such penalties would vary based on the nature and severity of the failure, including the potential termination of the electric service agreement.

Babel - Webre 500 kV Transmission Project

As discussed in the Form 10-K, in December 2025, Entergy Louisiana filed an application with the LPSC seeking a certificate of public convenience and necessity for a 500 kV transmission project that includes the construction of a new 147-mile Babel to Webre 500 kV transmission line, the reconstruction of the Webre 500 kV switching station in Louisiana, and coordination with Entergy Texas on the construction of an approximately 4-mile 500 kV transmission line in Texas. The project was approved by MISO in the 2025 MISO Transmission Expansion

Plan and has an estimated cost of $1,238 million and an estimated in-service date of August 2029. A procedural schedule has been set with a hearing scheduled for September 2026. Discovery is ongoing.

Waterford 6 Power Station and Westlake Power Station

As discussed in the Form 10-K, in February 2026, Entergy Louisiana filed an application seeking LPSC approval and certification to construct two 754 MW combined cycle combustion turbine generators, the Waterford 6 Power Station and the Westlake Power Station, to be located at Entergy Louisiana’s existing Waterford site near Killona, Louisiana and existing Roy S. Nelson site in Westlake, Louisiana, respectively. In its application, Entergy Louisiana noted the estimated costs are approximately $2,027 million for the Waterford 6 Power Station and $2,091 million for the Westlake Power Station. As described in the application, Entergy Louisiana is considering a third-party financing approach for the Waterford 6 Power Station. Entergy Louisiana asked that the LPSC consider the requests in the application at or before its December 2026 meeting. A procedural schedule has been set with hearings scheduled in October and November 2026. The estimated in-service dates for the Waterford 6 Power Station and Westlake Power Station are July 2030 and October 2030, respectively.

Entergy Mississippi Additional Generation and Transmission Resources

As discussed in the Form 10-K, in March 2024, Entergy Mississippi executed a large customer supply and service agreement to serve two data center campuses located in Madison County, Mississippi in which Amazon Web Services is investing. In February 2025, Entergy Mississippi executed a large customer supply and service agreement to serve a data center campus located in Warren County, Mississippi in which Amazon Web Services is investing. In April 2026, Amazon Web Services announced the expansion of the data center campuses located in Madison County, Mississippi. The February 2025 agreement will serve this expansion. Also, in April 2026, Entergy Mississippi executed a large customer supply and service agreement to serve a data center campus located in Hinds County, Mississippi in which Amazon Web Services is investing. Consistent with Entergy Mississippi’s Fair Share Plus guidelines, the large customer supply and service agreements are structured to ensure that the customer pays its incremental cost to serve and includes protections in the event of early termination.

Dividends

Declarations of dividends on Entergy Corporation common stock are made at the discretion of the Board. Among other things, the Board evaluates the level of Entergy Corporation common stock dividends based upon earnings per share from the Utility segment and the Parent and Other portion of the business, financial strength, and future investment opportunities. In April 2026 the Board declared a dividend of $0.64 per share.

Cash Flow Activity

As shown in Entergy’s Consolidated Statements of Cash Flows, cash flows for the three months ended March 31, 2026 and 2025 were as follows:

Net cash flow provided by operating activities increased $293 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 primarily due toan increase of $294 million in receipts of advance payments related to customer agreements, including $263 million in customer advances and $31 million in tax gross-up on customer advances for construction, and higher collections from Utility customers. The increase was partially offset byhigher fuel and purchased power payments and the timing of payments to vendors. See Note 2 to the financial statements herein and in the Form 10-K for a discussion of fuel and purchased power cost recovery.

Net cash flow used in investing activities increased $711 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 primarily due to:

•an increase of $408 million in non-nuclear generation construction expenditures primarily due to higher spending by Entergy Arkansas on the Ironwood Power Station project and the Jefferson Power Station project, by Entergy Louisiana on the Richland Parish Power Station Units 1 and 2 project, the Waterford 5 Power Station project, and the Waterford 6 Power Station project, and by Entergy Mississippi on the Traceview Advanced Power Station project; partially offset by lower spending by Entergy Texas on the Orange County Advanced Power Station project in 2026 and lower spending on the Legend Power Station project as a result of the sale of assets related to the in-process project in December 2025. See Note 8 to the financial statements in the Form 10-K for discussion of the Entergy Texas build-to-suit lease arrangement for the Legend Power Station;

•an increase of $136 million in capital expenditures related to storm restoration primarily due to Winter Storm Fern. See “Winter Storm Fern” above for discussion of storm restoration efforts in 2026;

•an increase of $65 million in transmission construction expenditures primarily due to higher spending by Entergy Louisiana on the Amite South transmission projects, increased spending on various other transmission projects, and higher capital expenditures as a result of increased development in the Utility service area in 2026;

•an increase of $62 million in nuclear fuel purchases due to variations from year to year in the timing and pricing of fuel reload requirements, materials and services deliveries, and the timing of cash payments during the nuclear fuel cycle; and

•payments to storm reserve escrow accounts of $3 million in 2026 compared to net receipts from storm reserve escrow accounts of $39 million in 2025.

The increase was partially offset by a decrease of $128 million in nuclear construction expenditures primarily due to decreased spending on various nuclear projects in 2026.

Net cash flow provided by financing activities increased $1,407 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 primarily due to:

•long-term debt activity providing approximately $2,391 million of cash in 2026 compared to providing approximately $1,595 million of cash in 2025;

•$346 million in net proceeds from the issuance of common stock in forward contracts under the at the market equity distribution program in 2026. There were no issuances of common stock under the at the market equity distribution program in 2025; and

•an increase of $322 million in net issuances of commercial paper in 2026 as compared to 2025.

The increase was partially offset by an increase of $35 million in common stock dividends paid in 2026 as compared to 2025 as a result of an increase in the dividend paid per share and an increase in the number of shares outstanding. See Note 3 to the financial statements herein and Note 7 to the financial statements in the Form 10-K for discussion of the equity distribution program. See Note 4 to the financial statements herein and Notes 4 and 5 to the financial statements in the Form 10-K for details of Entergy’s commercial paper program and long-term debt.

Rate, Cost-recovery, and Other Regulation

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS - Rate, Cost-recovery, and Other Regulation” in the Form 10-K for discussions of rate regulation, federal regulation, and related regulatory proceedings.

See Note 2 to the financial statements herein for updates to the discussion in the Form 10-K regarding these proceedings.

See Note 2 to the financial statements herein for updates to the discussion in the Form 10-K regarding federal regulatory proceedings.

Market and Credit Risk Sensitive Instruments

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS – Market and Credit Risk Sensitive Instruments” in the Form 10-K for a discussion of market and credit risk sensitive instruments. The following are updates to that discussion.

Some of the agreements to sell the power produced by Entergy’s non-utility operations business contain provisions that require an Entergy subsidiary to provide credit support to secure its obligations under such agreements. The primary form of credit support used to satisfy these requirements is an Entergy Corporation guarantee. Cash and letters of credit are also acceptable forms of credit support. At March 31, 2026, based on power prices at that time, Entergy had $10 million of posted cash collateral.

In addition to the ability to post cash collateral, each of the Utility operating companies has uncommitted standby letter of credit facilities as a means to post collateral to support its obligations to MISO and for other purposes. See Note 4 to the financial statements herein for discussion of these letter of credit facilities. As of March 31, 2026, Entergy Arkansas had $37 million of posted cash collateral, Entergy Louisiana had $67 million of posted cash collateral, and Entergy New Orleans had $5 million of posted cash collateral.

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS – Nuclear Matters” in the Form 10-K for a discussion of nuclear matters. The following is an update to that discussion.

NRC Reactor Oversight Process

The NRC’s Reactor Oversight Process is a program to collect information about plant performance, assess the information for its safety significance, and provide for appropriate licensee and NRC response. The NRC evaluates plant performance by analyzing two distinct inputs: inspection findings resulting from the NRC’s inspection program and performance indicators reported by the licensee. The evaluations result in the placement of each plant in one of the NRC’s Reactor Oversight Process Action Matrix columns: “licensee response column,” or Column 1, “regulatory response column,” or Column 2, “degraded cornerstone column,” or Column 3, “multiple/repetitive degraded cornerstone column,” or Column 4, and “unacceptable performance,” or Column 5. Plants in Column 1 are subject to normal NRC inspection activities. Plants in Column 2, Column 3, or Column 4 are subject to progressively increasing levels of inspection by the NRC with, in general, progressively increasing levels of associated costs. Continued plant operation is not permitted for plants in Column 5. All of the nuclear generating plants owned and operated by Entergy’s Utility business are currently in Column 1.

In March 2026 the NRC issued an inspection report for Grand Gulf, in which it identified a preliminary “white” finding with “low safety significance” related to one of Grand Gulf’s emergency diesel generators. The NRC is continuing its evaluation of the issue and is expected to complete its determination during second quarter 2026. If the NRC’s review results in a final white finding, Grand Gulf would be placed in Column 2 and would remain in Column 2 until the satisfactory completion of an NRC supplemental inspection.
