ENTERGY ARKANSAS, LLC

ENTERGY TEXAS, INC. AND SUBSIDIARIES

Net income decreased $8.7 million primarily due to higher purchased power costs related to the procurement of capacity through MISO’s annual planning resource auction, partially offset by higher retail electric price and higher other income.

Net income increased $21.4 million primarily due to higher retail electric price, higher volume/weather, and higher other income, partially offset by higher purchased power costs related to the procurement of capacity through MISO’s annual planning resource auction, higher taxes other than income taxes, and higher interest expense.

Entergy Texas’s 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 the implementation of the distribution cost recovery factor rider effective with the first billing cycle in October 2024 and an increase in the distribution cost recovery factor rider effective in late December 2024. See Note 2 to the financial statements in the Form 10-K for discussion of the distribution cost recovery factor rider filings.

The volume/weather variance is primarily due to an increase in industrial and commercial usage. The increase in industrial usage is primarily due to an increase in demand from large industrial customers, primarily in the primary metals, wood products, petroleum refining, and transportation industries, and an increase in demand from small industrial customers, partially offset by a decrease in demand from co-generation customers. The increase in commercial usage is primarily due to an increase in customers.

Total electric energy sales for Entergy Texas for the three months ended June 30, 2025 and 2024 are as follows:

See Note 12 to the financial statements herein for additional discussion of Entergy Texas’s operating revenues.

See Note 2 to the financial statements in the Form 10-K for discussion of the distribution cost recovery factor rider filings.

The volume/weather variance is primarily due to the effect of more favorable weather on residential sales, an increase in weather-adjusted residential usage, and an increase in commercial and industrial usage. The increase in weather-adjusted residential usage and the increase in commercial usage are primarily due to an increase in customers. The increase in industrial usage is primarily due to an increase in demand from large industrial customers, primarily in the wood products, petrochemicals, petroleum refining, and transportation industries, and an increase in demand from co-generation customers.

Total electric energy sales for Entergy Texas for the six months ended June 30, 2025 and 2024 are as follows:

See Note 12 to the financial statements herein for additional discussion of Entergy Texas’s operating revenues.

Purchased power includes an increase in second quarter 2025 of $20 million in costs related to the procurement of capacity through MISO’s annual planning resource auction, including the effect of a significant increase in MISO’s seasonal auction clearing price, due to the implementation of a reliability-based demand curve, for capacity transactions during the summer months. Although Entergy Texas does not have the ability to recover its MISO capacity costs incurred to date beyond the level included in base rates, in June 2025, Texas legislation established a capacity cost recovery rider mechanism that would allow for the recovery of costs related to the procurement of capacity through MISO’s annual planning resource auction outside of base rates, through a rider that is updated annually. Entergy Texas plans to file for such a rider to recover future capacity procurement costs at the earliest opportunity in 2026.

Depreciation and amortization expenses decreased primarily due to the recognition of $13.8 million in depreciation expense in second quarter 2024 for the 2022 base rate case relate back period, effective over six months beginning January 2024. The recognition of depreciation expense for the relate back period was effective over the same period as collections from the relate back surcharge rider and resulted in no effect on net income. See Note 2 to the financial statements in the Form 10-K for discussion of the 2022 base rate case. The decrease was partially offset by additions to plant in service.

Other income increased primarily due to an increase in the allowance for equity funds used during construction due to higher construction work in progress in 2025, including the Orange County Advanced Power Station project and the Legend Power Station project.

Interest expense increased primarily due to the issuance of $500 million of 5.25% Series mortgage bonds in February 2025 and the issuance of $350 million of 5.55% Series mortgage bonds in August 2024, partially offset by an increase in the allowance for borrowed funds used during construction due to higher construction work in progress in 2025, including the Orange County Advanced Power Station project and the Legend Power Station project.

Purchased power includes an increase in 2025 of $21 million in costs related to the procurement of capacity through MISO’s annual planning resource auction, including the effect of a significant increase in MISO’s seasonal auction clearing price, due to the implementation of a reliability-based demand curve, for capacity transactions during the summer months. Although Entergy Texas does not have the ability to recover its MISO capacity costs incurred to date beyond the level included in base rates, in June 2025, Texas legislation established a capacity cost recovery rider mechanism that would allow for the recovery of costs related to the procurement of capacity through MISO’s annual planning resource auction outside of base rates, through a rider that is updated annually. Entergy Texas plans to file for such a rider to recover future capacity procurement costs at the earliest opportunity in 2026.

Taxes other than income taxes increased primarily due to an increase in local franchise taxes as a result of higher retail revenues in 2025 as compared to 2024.

Depreciation and amortization expenses decreased primarily due to the recognition of $27.6 million in depreciation expense in 2024 for the 2022 base rate case relate back period, effective over six months beginning January 2024. The recognition of depreciation expense for the relate back period was effective over the same period as collections from the relate back surcharge rider and resulted in no effect on net income. See Note 2 to the financial statements in the Form 10-K for discussion of the 2022 base rate case. The decrease was partially offset by additions to plant in service.

Other income increased primarily due to an increase in the allowance for equity funds used during construction due to higher construction work in progress in 2025, including the Orange County Advanced Power Station project and the Legend Power Station project.

Interest expense increased primarily due to the issuance of $350 million of 5.55% Series mortgage bonds in August 2024 and the issuance of $500 million of 5.25% Series mortgage bonds in February 2025, partially offset by an increase in the allowance for borrowed funds used during construction due to higher construction work in progress in 2025, including the Orange County Advanced Power Station project and the Legend Power Station project.

The effective income tax rates were 16.7% for the second quarter 2025 and 16.2% for the six months ended June 30, 2025. The differences in the effective income tax ratesfor the second quarter 2025 and thesix months ended June 30, 2025 versus the federal statutory rate of 21% were primarily due to book and tax differences related to the allowance for equity funds used during construction.

The effective income tax rates were 18.4% for the second quarter 2024 and 18.6% for the six months ended June 30, 2024. The differences in the effective income tax rates forthe second quarter 2024 and the six months ended June 30, 2024 versus the federal statutory rate of 21% were primarily due to book and tax differences related to the allowance for equity funds used during construction and certain book and tax differences related to utility plant items.

Net cash flow provided by operating activities decreased $50.1 million for the six months ended June 30, 2025 compared to the six months ended June 30, 2024 primarily due to:

•the timing of recovery of fuel and purchased power costs and higher fuel and purchased power payments. See Note 2 to the financial statements in the Form 10-K for a discussion of fuel and purchased power cost recovery;

•an increase of $12.9 million in interest paid;

•an increase of $10.3 million in storm spending; and

•lower collections from customers.

Net cash flow used in investing activities increased$663.4 million for the six months ended June 30, 2025 compared to the six months ended June 30, 2024 primarily due to:

•money pool activity;

•an increase of $386.2 million in non-nuclear generation construction expenditures primarily due to higher spending on the Legend Power Station project, the Orange County Advanced Power Station project, and the Lone Star Power Station project;

•an increase of $30.1 million in transmission construction expenditures primarily due to increased spending on various transmission projects in 2025 and higher capital expenditures as a result of increased development in Entergy Texas’s service area; and

•an increase of $16 million in distribution construction expenditures primarily due to higher capital expenditures as a result of increased development in Entergy Texas’s service territory, partially offset by lower capital expenditures for storm restoration in 2025.

The increase was partially offset by a decrease of $17.3 million in information technology capital expenditures primarily due to decreased spending on technology upgrade projects in 2025 and cash collateral of $12.7 million posted in 2024 to support Entergy Texas’s obligation to MISO.

Decreases in Entergy Texas’s receivable from the money pool are a source of cash flow, and Entergy Texas’s receivable from the money pool decreased $13.7 million for the six months ended June 30, 2025 compared to decreasing by $296.7 million for the six months ended June 30, 2024. The money pool is an intercompany cash management program that makes possible intercompany borrowing and lending arrangements, and the money pool and other borrowing arrangements are designed to reduce the Registrant Subsidiaries’ dependence on external short-term borrowings.

Net cash flow provided by financing activities increased $443.3 million for the six months ended June 30, 2025 compared to the six months ended June 30, 2024 primarily due to the issuance of $500 million of 5.25% Series mortgage bonds in February 2025, partially offset by a decrease of $63.6 million in advance payments from customers for construction related to transmission, distribution, and generator interconnection agreements. See Note 4 to the financial statements herein and Note 5 to the financial statements in the Form 10-K for more details on long-term debt.

Entergy Texas’s debt to capital ratio is shown in the following table. The increase in the debt to capital ratio for Entergy Texas is primarily due to the net issuance of long-term debt in 2025.

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

Net debt consists of debt less cash and cash equivalents. Debt consists of finance lease obligations and long-term debt, including the currently maturing portion. Capital consists of debt and equity. 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 Texas 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 Texas’s financial condition because the securitization bonds are non-recourse to Entergy Texas, as more fully described in Note 5 to the financial statements in the Form 10-K. Entergy Texas 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 Texas’s financial condition because net debt indicates Entergy Texas’s outstanding debt position that could not be readily satisfied by cash and cash equivalents on hand.

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS -Liquidity and Capital Resources” in the Form 10-K for a discussion of Entergy Texas’s uses and sources of capital. The following are updates to the information provided in the Form 10-K.

Recent announcements of changes to international trade policy and tariffs and further similar changes may impact Entergy Texas’s business, operations, results of operations, and liquidity and capital resources. Potential impacts may include increases in costs associated with Entergy Texas’s capital investments or operation and maintenance expenses; operational impacts, such as supply chain, manufacturing, or raw materials sourcing disruptions which may affect Entergy Texas’s ability to make planned capital investments as and when expected and needed; legal uncertainties, such as potential legal or other challenges to presidential tariff authority; or broader economic risks, including shifting customer demand, impacts on customer investment decisions, and volatile or uncertain credit and capital markets, which may affect Entergy Texas’s ability to access needed capital. The nature and extent of any such effects will depend on, among other things, the specifics of the changes that are ultimately implemented both domestically and internationally, the responses of vendors, suppliers, and other counterparties to those changes, indirect effects on the price and availability of non-tariffed goods, and the effectiveness of mitigation measures.

Entergy Texas’s receivables from the money pool were as follows:

Entergy Texas has a credit facility in the amount of $300 million scheduled to expire in June 2030. The credit facility includes fronting commitments for the issuance of letters of credit against $25 million of the borrowing capacity of the facility. As of June 30, 2025, there were no cash borrowings and $1.1 million in letters of credit outstanding under the credit facility. In addition, Entergy Texas is a party to two uncommitted letter of credit facilities as a means to post collateral to support its obligations to MISO. As of June 30, 2025, $54.0 million in letters of credit were outstanding under one of Entergy Texas’s uncommitted letter of credit facilities. See Note 4 to the financial statements herein for additional discussion of the credit facilities.

Legend Power Station and Lone Star Power Station

As discussed in the Form 10-K, in June 2024, Entergy Texas filed an application seeking PUCT approval to amend Entergy Texas’s certificate of convenience and necessity to construct, own, and operate the Legend Power Station, a 754 MW combined cycle combustion turbine facility, which will be enabled for future carbon capture and storage and for hydrogen co-firing optionality, to be located in Jefferson County, Texas, and the Lone Star Power Station, a 453 MW simple-cycle combustion turbine facility, which will be enabled with hydrogen co-firing optionality, originally expected to be located in Liberty County, Texas. In March 2025, Entergy Texas filed testimony explaining that Entergy Texas planned to move forward with building the Lone Star Power Station on a more cost-effective alternative site in San Jacinto County, Texas. A hearing on the merits was held in April 2025. Also in April 2025, Entergy Texas, intervenors, and the PUCT staff filed initial briefs. In its initial brief, the PUCT staff recommends denial of Entergy Texas’s application or, in the alternative, approval subject to conditions that include a prudence review by an external consultant if actual project costs exceed estimated costs by more than 10%, transmission cost reporting, and weatherization of both the Legend Power Station and the Lone Star Power Station. Certain intervenors requested that the PUCT impose various conditions upon the approval of the resources, including, among others, cost recovery limitations, a direction that Entergy Texas initiate a competitive tariff proceeding to facilitate industrial sleeving, a requirement for additional regulatory approvals related to hydrogen or carbon capture and storage implementation, limits on the recovery of supplemental filing costs, and calculation of AFUDC based on an adjusted weighted average cost of capital. Reply briefs were filed in May 2025. In June 2025 the ALJs with the State Office of Administrative Hearings issued a proposal for decision, in which they recommended rejection of Entergy Texas’s application to construct the Legend Power Station and the Lone Star Power Station based upon their finding that Entergy Texas did not demonstrate the resources to be cost-effective alternatives to address the uncontested need for additional generation. In the alternative, the ALJs recommended that if the PUCT approves the resources, that conditions be imposed, including a deferral of the finding that the resources were prudently selected until Entergy Texas’s next rate case, a prudence review by an external consultant if actual project costs exceed estimated costs by more than 10%, weatherization requirements, and a requirement that Entergy Texas obtain additional regulatory approvals prior to implementing hydrogen co-firing or carbon capture and storage. The ALJs’ proposal for decision is an interim step in the certification process, and it is not binding upon the PUCT. Entergy Texas filed exceptions in July 2025. A PUCT decision is expected in third quarter 2025. Subject to receipt of required regulatory approval and other conditions, both facilities are expected to be in service by mid-2028.

Segno Solar and Votaw Solar

As discussed in the Form 10-K, in July 2024, Entergy Texas filed an application seeking PUCT approval to amend Entergy Texas’s certificate of convenience and necessity to construct, own, and operate the Segno Solar facility, a 170 MW solar facility to be located in Polk County, Texas, and the Votaw Solar facility, a 141 MW solar facility to be located in Hardin County, Texas. In July 2025, Entergy Texas filed, and the ALJs with the State Office of Administrative Hearings granted, an unopposed motion to abate this proceeding to give the parties to the proceeding additional time for settlement discussions.

Southeast Texas Area Reliability Project (SETEX)

In February 2025, Entergy Texas filed an application seeking PUCT approval to amend Entergy Texas’s certificate of convenience and necessity to construct, own, and operate a new single-circuit 500 kV transmission line and associated stations and 138/230 kV facilities. The transmission line is expected to be approximately 131 to 160 miles in length and the estimated cost of the project ranges from $1.3 billion to $1.5 billion, depending upon the route ultimately approved by the PUCT. Also in February 2025 the PUCT referred the proceeding to the State Office of Administrative Hearings. A hearing on the merits was held in May 2025. In July 2025 the ALJs with the State Office of Administrative Hearings issued a proposal for decision recommending the PUCT approve Entergy Texas’s application to construct SETEX and recommending the PUCT’s approval include selection of a specific route with an estimated cost of $1.4 billion. A PUCT decision is expected in third quarter 2025. Subject to receipt of required regulatory approval and other conditions, construction of the project is expected to be completed by the end of 2029.

Legend to Sandling 230kV Transmission Line

In April 2025, Entergy Texas filed an application seeking PUCT approval to amend Entergy Texas’s certificate of convenience and necessity to construct, own, and operate a new single-circuit 230 kV transmission line. The transmission line is expected to be approximately 9 to 10 miles in length and the estimated cost of the project ranges from $87.4 million to $88.6 million, depending on the route ultimately approved by the PUCT. Also in April 2025 the PUCT referred the proceeding to the State Office of Administrative Hearings. In July 2025, Entergy Texas filed an unopposed settlement agreement resolving all issues in the proceeding and a joint motion, which the ALJ with the State Office of Administrative Hearings granted, on behalf of the parties to the proceeding to cancel the remaining procedural schedule, to admit evidence, and to remand the proceeding to the PUCT to consider the unopposed settlement agreement. A PUCT decision is expected in fourth quarter 2025. Subject to receipt of required regulatory approval and other conditions, construction of the project is expected to be completed by second quarter 2027.

Cypress to Legend 500 kV Transmission Line

In May 2025, Entergy Texas filed an application seeking PUCT approval to amend Entergy Texas’s certificate of convenience and necessity to construct, own, and operate a new single-circuit 500 kV transmission line. The transmission line is expected to be approximately 40 to 49 miles in length and the estimated cost of the project ranges from $392.7 million to $436.2 million, depending on the route ultimately approved by the PUCT. In June 2025 the PUCT referred the proceeding to the State Office of Administrative Hearings and the ALJs with the State Office of Administrative Hearings adopted a procedural schedule with a hearing on the merits to be held in mid-August 2025. A PUCT decision is expected in fourth quarter 2025. Subject to receipt of required regulatory approval and other conditions, construction of the project is expected to be completed by the end of 2028.

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS - State and Local Rate Regulation and Fuel-Cost Recovery” in the Form 10-K for a discussion of state and local rate regulation and fuel-cost recovery. The following are updates to that discussion.

Distribution Cost Recovery Factor (DCRF) Rider

In April 2025, Entergy Texas filed with the PUCT a request to amend its DCRF rider. The amended rider was designed to collect from Entergy Texas’s retail customers approximately $77.8 million annually, or $29.3 million in incremental annual revenues beyond Entergy Texas’s then-effective DCRF rider based on its capital invested in distribution between July 1, 2024 and December 31, 2024, including distribution-related restoration costs associated with Hurricane Beryl. In June 2025 the PUCT approved the DCRF rider, consistent with Entergy Texas’s as-filed request, and rates became effective on June 25, 2025.

Transmission Cost Recovery Factor (TCRF) Rider

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

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

SYSTEM ENERGY RESOURCES, INC.

System Energy’s principal asset consists of an ownership interest and a leasehold interest in Grand Gulf. The capacity and energy from its 90% interest is sold under the Unit Power Sales Agreement to its only four customers, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, and Entergy New Orleans. System Energy’s operating revenues are derived from the allocation of the capacity, energy, and related costs associated with its 90% interest in Grand Gulf pursuant to the Unit Power Sales Agreement. Payments under the Unit Power Sales Agreement are System Energy’s only source of operating revenues. See “Complaints Against System Energy - System Energy Settlement with the LPSC”in Note 2 to the financial statements herein for additional information regarding filings made with the FERC in May 2025 related to the Unit Power Sales Agreement. Also, as discussed in “Complaints Against System Energy” in Note 2 to the financial statements in the Form 10-K, System Energy and the Unit Power Sales Agreement have been the subject of several litigation proceedings at the FERC. Settlements that resolve all significant aspects of these complaints have been reached with the MPSC, the APSC, the City Council, and the LPSC, and these settlements have been approved by the FERC.

Net income decreased $3.5 million primarily due a lower rate of return on rate base, including the effects of lower authorized rate of return on equity and capital structure limitations reflected in monthly bills issued to Entergy New Orleans effective with the June 2024 service month per the settlement agreement with the City Council and the lower authorized rate of return on equity and capital structure limitations reflected in monthly bills issued to Entergy Louisiana effective with the September 2024 service month per the settlement with the LPSC, and lower operating revenues resulting from changes in rate base. See Note 2 to the financial statements in the Form 10-K for discussion of the settlements with the City Council and the LPSC.

Net income decreased $11.3 million primarily due a lower rate of return on rate base, including the effects of lower authorized rate of return on equity and capital structure limitations reflected in monthly bills issued to Entergy New Orleans effective with the June 2024 service month per the settlement agreement with the City Council and the lower authorized rate of return on equity and capital structure limitations reflected in monthly bills issued to Entergy Louisiana effective with the September 2024 service month per the settlement with the LPSC. The decrease was partially offset by higher operating revenues resulting from changes in rate base. See Note 2 to the financial statements in the Form 10-K for discussion of the settlements with the City Council and the LPSC.

The effective income tax rates were 19.4% for the second quarter 2025 and 20.3% for the six months ended June 30, 2025. The differences in the effective income tax rates for the second quarter 2025 and the six months ended June 30, 2025 versus the federal statutory rate of 21% were primarily due to 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 rates were 23.2% for the second quarter 2024 and 21.7% for the six months ended June 30, 2024. The differences in the effective income tax rates for the second quarter 2024 and the six months ended June 30, 2024 versus the federal statutory rate of 21% were primarily due to the accrual for state income taxes, partially offset by book and tax differences related to the allowance for equity funds used during construction.

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS -Income Tax Legislation and Regulation” herein and in the Form 10-K for discussion of income tax legislation and regulation. See Note 10 to the financial statements herein for discussion of the nuclear production tax credits recorded in second quarter 2025.

Net cash flow provided by operating activities increased $104.1 million for the six months ended June 30, 2025 compared to the six months ended June 30, 2024 primarily due to the refund of $92 million made in May 2024 to Entergy Arkansas as a result of the settlement with the APSC and a decrease of $20.4 million in spending on nuclear refueling outage costs in 2025 as compared to 2024. See Note 2 to the financial statements in the Form 10-K for discussion of the settlement with the APSC.

Net cash flow used in investing activities decreased $160.7 million for the six months ended June 30, 2025 compared to the six months ended June 30, 2024 primarily due to net proceeds of $16.6 million in 2025 compared to net purchases of $115.5 million in 2024 as a result of fluctuations in nuclear fuel activity due to variations from year to year in the timing and pricing of fuel reload requirements, material and services deliveries, and the timing of cash payments during the nuclear fuel cycle and a decrease of $31.8 million in nuclear construction expenditures primarily due to higher spending in 2024 on Grand Gulf outage projects and upgrades.

System Energy’s financing activities used $72.6 million of cash for the six months ended June 30, 2025 compared to providing $220.3 million of cash for the six months ended June 30, 2024 primarily due to the following activity:

•the repayment, prior to maturity, of $200 million of 2.14% Series mortgage bonds in June 2025;

•a capital contribution of $150 million received from Entergy Corporation in January 2024 in order to maintain System Energy’s capital structure;

•net repayments of $28.4 million in 2025 compared to net long-term borrowings of $82.6 million in 2024 on the nuclear fuel company variable interest entity’s credit facility;

•$75 million in common stock dividends and distributions paid in 2025. No common stock dividends or distributions were paid in 2024 in anticipation of the settlements with the APSC, the LPSC, and the City Council; and

•the issuance of $240 million of 5.30% Series mortgage bonds in May 2025.

System Energy’s debt to capital ratio is shown in the following table.

Net debt consists of debt less cash and cash equivalents. Debt consists of short-term borrowings and long-term debt, including the currently maturing portion. Capital consists of debt and common equity. Net capital consists of capital less cash and cash equivalents. System Energy uses the debt to capital ratio in analyzing its financial condition and believes it provides useful information to its investors and creditors in evaluating System Energy’s financial condition. The net debt to net capital ratio is a non-GAAP measure. System Energy uses the net debt to net capital ratio in analyzing its financial condition and believes it provides useful information to its investors and creditors in evaluating System Energy’s financial condition because net debt indicates System Energy’s outstanding debt position that could not be readily satisfied by cash and cash equivalents on hand.

See “MANAGEMENT’S FINANCIAL DISCUSSION AND ANALYSIS -Liquidity and Capital Resources” in the Form 10-K for a discussion of System Energy’s uses and sources of capital. The following are updates to the information provided in the Form 10-K.

Recent announcements of changes to international trade policy and tariffs and further similar changes may impact System Energy’s business, operations, results of operations, and liquidity and capital resources. Potential impacts may include increases in costs associated with System Energy’s capital investments or operation and maintenance expenses; operational impacts, such as supply chain, manufacturing, or raw materials sourcing disruptions which may affect System Energy’s ability to make planned capital investments as and when expected and needed; legal uncertainties, such as potential legal or other challenges to presidential tariff authority; or broader economic risks, including shifting customer demand, impacts on customer investment decisions, and volatile or uncertain credit and capital markets, which may affect System Energy’s ability to access needed capital. The nature and extent of any such effects will depend on, among other things, the specifics of the changes that are ultimately implemented both domestically and internationally, the responses of vendors, suppliers, and other counterparties to those changes, indirect effects on the price and availability of non-tariffed goods, and the effectiveness of mitigation measures.

System Energy’s receivables from or (payables to) the money pool were as follows:

The System Energy nuclear fuel company variable interest entity has a credit facility in the amount of $120 million scheduled to expire in June 2027. As of June 30, 2025, $44.3 million in loans were outstanding under the System Energy nuclear fuel company variable interest entity credit facility. See Note 4 to the financial statements herein for additional discussion of the variable interest entity credit facility.

Complaints Against System Energy

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

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

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

System Energy Settlement with the LPSC

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

Louisiana as a party to the Unit Power Sales Agreement. As a result of the order, the Unit Power Sales Agreement entitlement percentages of the remaining purchasers will be permanently modified to exclude Entergy Louisiana, to be effective beginning October 2025. The FERC also issued an order dismissing the Federal Power Act Section 203 application based on lack of jurisdiction.
