Income Tax Disclosure [Text Block]	INCOME TAXES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) See “Income Tax Audits” and “Other Tax Matters” in Note 3 to the financial statements in the Form 10-K for a discussion of income tax audits, the Tax Cuts and Jobs Act, and other income tax matters involving Entergy. The following are updates to that discussion. Other Tax Matters Inflation Reduction Act of 2022 As discussed in the Note 3 to the financial statements in the Form 10-K, the Inflation Reduction Act, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power facilities. Entergy Arkansas, Entergy Louisiana, and System Energy have the potential to generate zero-emission nuclear power production tax credits for electricity generated by their respective nuclear power facilities. Due to the uncertainty of the value, if any, of production tax credits Entergy Arkansas, Entergy Louisiana, or System Energy may receive, such credits for the nuclear power produced in 2024 were not recognized as of December 31, 2024. In second quarter 2025, Entergy, Entergy Arkansas, Entergy Louisiana, and System Energy determined, based on current analysis and evolving regulatory developments, that it was appropriate to record zero-emission nuclear production tax credits under Internal Revenue Code section 45U for electricity generated in 2024 by their respective nuclear power facilities. Such credits have been claimed on the Entergy 2024 federal income tax return. Because the U.S. Treasury and the IRS have not issued final guidance regarding the application of Internal Revenue Code section 45U, including the definition of “gross receipts,” Entergy treated the full amount of the Internal Revenue Code section 45U credits as an uncertain tax position in accordance with the income tax accounting standards. The value of the nuclear production tax credits was calculated based on the amount of electricity generated and sold by each nuclear generating unit owned by Entergy Arkansas, Entergy Louisiana, and System Energy during 2024, multiplied by the applicable credit rate (i.e. dollars per kWh). The applicable credit rate included the incremental amount of credit for meeting the “prevailing wages” criteria under the Inflation Reduction Act. Entergy also applied the statutorily required reduction amount in arriving at the value of the nuclear production tax credits. This reduction amount was driven by the “gross receipts” received by each unit for its 2024 energy production. Entergy Arkansas, Entergy Louisiana, and System Energy recognized nuclear production tax credits of $221.4 million, $208.9 million, and $140.9 million, respectively, resulting in Entergy consolidated nuclear production tax credits of $571.2 million recognized in second quarter 2025. To the extent future guidance allows Entergy to realize the value of the credits under the provisions of income tax accounting standards, the monetized value of the production tax credits, net of applicable expenses, is expected to be shared with customers. In September 2025, Entergy Arkansas, Entergy Louisiana, and System Energy transferred nuclear production tax credits to third parties and received cash of $155.1 million, $146.4 million, and $98.7 million, respectively, resulting in total Entergy cash receipts of $400.2 million. The proceeds from the transfers reflected a market-based discount. In addition, Entergy Arkansas sold its solar production tax credits to a third party and received cash receipts of approximately $5.1 million. Entergy Arkansas, Entergy Louisiana, System Energy, and the relevant affiliates, as necessary, have submitted filings or are preparing to file with the FERC and their respective retail regulators to determine a fair and reasonable approach, including risk-sharing and timing, to incorporate the net cash proceeds received for nuclear production tax credits into future customer rates, particularly in light of the related provision for the uncertain tax position. In August 2025 the LPSC issued an order approving an agreement between Entergy Louisiana and the LPSC staff regarding the monetization of 2024 nuclear production tax credits. The order allows Entergy Louisiana to retain the net proceeds of the nuclear production tax credits while the associated tax position remains uncertain. While it retains the net proceeds, Entergy Louisiana will accrue a liability to its customers at its weighted average cost of capital. It further provides that customers will be responsible for the associated costs should the IRS reduce some or all of the value of the nuclear production tax credits transferred to third parties. Once the IRS makes a final determination affirming the value of the nuclear production tax credits or the audit period expires without the IRS making a final determination disallowing some or all of the value of the nuclear production tax credits, Entergy Louisiana will commence flowing to its customers the value of the nuclear production tax credits, including carrying charges. Entergy will continue to monitor further developments and reassess the uncertain tax position as additional guidance or other information emerges. Additional cash receipts for the transfer of the remaining 2024 nuclear production tax credits to third parties were received in October 2025 of $55 million, $51.9 million, and $35.1 million by Entergy Arkansas, Entergy Louisiana, and System Energy, respectively, resulting in additional Entergy cash receipts of $142 million. The proceeds from these transfers also reflected a market-based discount. Sale of Natural Gas Distribution Businesses See Note 13 to the financial statements herein for discussion of the sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses on July 1, 2025. Entergy recognized a gain of approximately $327 million for tax purposes, with Entergy Louisiana and Entergy New Orleans recognizing $148 million and $179 million, respectively. Both Entergy and Entergy Louisiana have sufficient federal tax net operating loss carryforwards to offset their respective gains. Accordingly, Entergy does not have a resulting federal income tax obligation as a result of the transaction, nor will Entergy Louisiana be required to make a federal tax payment under the terms of the intercompany income tax allocation agreement. Entergy New Orleans is expected to fully absorb its federal tax net operating loss carryforward in 2025, and its resulting federal tax payment under the intercompany income tax allocation agreement will be dependent on its results of operations for the entire year. Estimated state tax payments for Entergy, Entergy Louisiana, and Entergy New Orleans are not anticipated to be significant.

In September 2025, Entergy Arkansas, Entergy Louisiana, and System Energy transferred nuclear production tax credits to third parties and received cash of $155.1 million, $146.4 million, and $98.7 million, respectively, resulting in total Entergy cash receipts of $400.2 million. The proceeds from the transfers reflected a market-based discount. In addition, Entergy Arkansas sold its solar production tax credits to a third party and received cash receipts of approximately $5.1 million. Entergy Arkansas, Entergy Louisiana, System Energy, and the relevant affiliates, as necessary, have submitted filings or are preparing to file with the FERC and their respective retail regulators to determine a fair and reasonable approach, including risk-sharing and timing, to incorporate the net cash proceeds received for nuclear production tax credits into future customer rates, particularly in light of the related provision for the uncertain tax position. In August 2025 the LPSC issued an order approving an agreement between Entergy Louisiana and the LPSC staff regarding the monetization of 2024 nuclear production tax credits. The order allows Entergy Louisiana to retain the net proceeds of the nuclear production tax credits while the associated tax position remains uncertain. While it retains the net proceeds, Entergy Louisiana will accrue a liability to its customers at its weighted average cost of capital. It further provides that customers will be responsible for the associated costs should the IRS reduce some or all of the value of the nuclear production tax credits transferred to third parties. Once the IRS makes a final determination affirming the value of the nuclear production tax credits or the audit period expires without the IRS making a final determination disallowing some or all of the value of the nuclear production tax credits, Entergy Louisiana will commence flowing to its customers the value of the nuclear production tax credits, including carrying charges. Entergy will continue to monitor further developments and reassess the uncertain tax position as additional guidance or other information emerges. Additional cash receipts for the transfer of the remaining 2024 nuclear production tax credits to third parties were received in October 2025 of $55 million, $51.9 million, and $35.1 million by Entergy Arkansas, Entergy Louisiana, and System Energy, respectively, resulting in additional Entergy cash receipts of $142 million. The proceeds from these transfers also reflected a market-based discount. Sale of Natural Gas Distribution Businesses See Note 13 to the financial statements herein for discussion of the sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses on July 1, 2025.

Both Entergy and Entergy Louisiana have sufficient federal tax net operating loss carryforwards to offset their respective gains. Accordingly, Entergy does not have a resulting federal income tax obligation as a result of the transaction, nor will Entergy Louisiana be required to make a federal tax payment under the terms of the intercompany income tax allocation agreement. Entergy New Orleans is expected to fully absorb its federal tax net operating loss carryforward in 2025, and its resulting federal tax payment under the intercompany income tax allocation agreement will be dependent on its results of operations for the entire year.

Other Tax Matters Inflation Reduction Act of 2022 As discussed in the Note 3 to the financial statements in the Form 10-K, the Inflation Reduction Act, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power facilities. Entergy Arkansas, Entergy Louisiana, and System Energy have the potential to generate zero-emission nuclear power production tax credits for electricity generated by their respective nuclear power facilities. Due to the uncertainty of the value, if any, of production tax credits Entergy Arkansas, Entergy Louisiana, or System Energy may receive, such credits for the nuclear power produced in 2024 were not recognized as of December 31, 2024.

Such credits have been claimed on the Entergy 2024 federal income tax return.

The applicable credit rate included the incremental amount of credit for meeting the “prevailing wages” criteria under the Inflation Reduction Act.

Entergy New Orleans is expected to fully absorb its federal tax net operating loss carryforward in 2025, and its resulting federal tax payment under the intercompany income tax allocation agreement will be dependent on its results of operations for the entire year. Estimated state tax payments for Entergy, Entergy Louisiana, and Entergy New Orleans are not anticipated to be significant.

See “Income Tax Audits” and “Other Tax Matters” in Note 3 to the financial statements in the Form 10-K for a discussion of income tax audits, the Tax Cuts and Jobs Act, and other income tax matters involving Entergy. The following are updates to that discussion.

Other Tax Matters

Inflation Reduction Act of 2022

As discussed in the Note 3 to the financial statements in the Form 10-K, the Inflation Reduction Act, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power facilities. Entergy Arkansas, Entergy Louisiana, and System Energy have the potential to generate zero-emission nuclear power production tax credits for electricity generated by their respective nuclear power facilities. Due to the uncertainty of the value, if any, of production tax credits Entergy Arkansas, Entergy Louisiana, or System Energy may receive, such credits for the nuclear power produced in 2024 were not recognized as of December 31, 2024.

In second quarter 2025, Entergy, Entergy Arkansas, Entergy Louisiana, and System Energy determined, based on current analysis and evolving regulatory developments, that it was appropriate to record zero-emission nuclear production tax credits under Internal Revenue Code section 45U for electricity generated in 2024 by their respective nuclear power facilities. Such credits have been claimed on the Entergy 2024 federal income tax return. Because the U.S. Treasury and the IRS have not issued final guidance regarding the application of Internal Revenue Code section 45U, including the definition of “gross receipts,” Entergy treated the full amount of the Internal Revenue Code section 45U credits as an uncertain tax position in accordance with the income tax accounting standards.

The value of the nuclear production tax credits was calculated based on the amount of electricity generated and sold by each nuclear generating unit owned by Entergy Arkansas, Entergy Louisiana, and System Energy during 2024, multiplied by the applicable credit rate (i.e. dollars per kWh). The applicable credit rate included the incremental amount of credit for meeting the “prevailing wages” criteria under the Inflation Reduction Act. Entergy also applied the statutorily required reduction amount in arriving at the value of the nuclear production tax credits. This reduction amount was driven by the “gross receipts” received by each unit for its 2024 energy production. Entergy Arkansas, Entergy Louisiana, and System Energy recognized nuclear production tax credits of $221.4 million, $208.9 million, and $140.9 million, respectively, resulting in Entergy consolidated nuclear production tax credits of $571.2 million recognized in second quarter 2025. To the extent future guidance allows Entergy to realize the value of the credits under the provisions of income tax accounting standards, the monetized value of the production tax credits, net of applicable expenses, is expected to be shared with customers.

In September 2025, Entergy Arkansas, Entergy Louisiana, and System Energy transferred nuclear production tax credits to third parties and received cash of $155.1 million, $146.4 million, and $98.7 million, respectively, resulting in total Entergy cash receipts of $400.2 million. The proceeds from the transfers reflected a market-based discount. In addition, Entergy Arkansas sold its solar production tax credits to a third party and received cash receipts of approximately $5.1 million. Entergy Arkansas, Entergy Louisiana, System Energy, and the relevant affiliates, as necessary, have submitted filings or are preparing to file with the FERC and their respective retail regulators to determine a fair and reasonable approach, including risk-sharing and timing, to incorporate the net cash proceeds received for nuclear production tax credits into future customer rates, particularly in light of the related provision for the uncertain tax position. In August 2025 the LPSC issued an order approving an agreement between Entergy Louisiana and the LPSC staff regarding the monetization of 2024 nuclear production tax credits. The order allows Entergy Louisiana to retain the net proceeds of the nuclear production tax credits while the associated tax position remains uncertain. While it retains the net proceeds, Entergy Louisiana will accrue

a liability to its customers at its weighted average cost of capital. It further provides that customers will be responsible for the associated costs should the IRS reduce some or all of the value of the nuclear production tax credits transferred to third parties. Once the IRS makes a final determination affirming the value of the nuclear production tax credits or the audit period expires without the IRS making a final determination disallowing some or all of the value of the nuclear production tax credits, Entergy Louisiana will commence flowing to its customers the value of the nuclear production tax credits, including carrying charges. Entergy will continue to monitor further developments and reassess the uncertain tax position as additional guidance or other information emerges.

Additional cash receipts for the transfer of the remaining 2024 nuclear production tax credits to third parties were received in October 2025 of $55 million, $51.9 million, and $35.1 million by Entergy Arkansas, Entergy Louisiana, and System Energy, respectively, resulting in additional Entergy cash receipts of $142 million. The proceeds from these transfers also reflected a market-based discount.

Sale of Natural Gas Distribution Businesses

See Note 13 to the financial statements herein for discussion of the sale of the Entergy New Orleans and Entergy Louisiana natural gas distribution businesses on July 1, 2025. Entergy recognized a gain of approximately $327 million for tax purposes, with Entergy Louisiana and Entergy New Orleans recognizing $148 million and $179 million, respectively. Both Entergy and Entergy Louisiana have sufficient federal tax net operating loss carryforwards to offset their respective gains. Accordingly, Entergy does not have a resulting federal income tax obligation as a result of the transaction, nor will Entergy Louisiana be required to make a federal tax payment under the terms of the intercompany income tax allocation agreement. Entergy New Orleans is expected to fully absorb its federal tax net operating loss carryforward in 2025, and its resulting federal tax payment under the intercompany income tax allocation agreement will be dependent on its results of operations for the entire year.
