EXPLANATORY NOTE

IPALCO Enterprises, Inc. (the “Company,” “IPALCO,” “we,” “us” and “our”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to amend the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 10-K”), originally filed with the Securities and Exchange Commission (the “SEC”) on February 27, 2024, to include the information required by Items 10 through 13 of Part III of Form 10-K. This information was previously omitted from the 2023 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above-referenced items to be incorporated in the Form 10-K by reference from the Company’s definitive proxy statement or to be provided as an amendment to Form 10-K, if such statement or amendment is filed no later than 120 days after the Company’s fiscal year-end. The Company is filing this Amendment to provide certain information required by Part III (Items 10, 11, 12 and 13) of Form 10-K to be incorporated by reference into the 2023 10-K and to delete the references to the definitive proxy statement in Part III of the 2023 10-K. The cover page of the 2023 10-K is also amended to delete the reference to the incorporation by reference of the definitive proxy statement.

Except as described above, no other changes have been made to the 2023 10-K, and this Amendment does not modify, amend or update in any way any of the financial or other information contained in the 2023 10-K. This Amendment does not reflect events occurring after the date of the filing of the 2023 10-K, nor does it amend, modify or otherwise update any other information in the 2023 10-K, except as noted in the immediately preceding paragraph. Accordingly, this Amendment should be read in conjunction with the 2023 10-K and with our filings with the SEC subsequent to the filing of the 2023 10-K.

In addition, pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Amendment also amends and restates Part IV, Item 15 to include the currently dated certifications from the Company’s principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which are attached hereto, and other applicable exhibits. Because no financial statements have been included in this

Amendment and this Amendment does not contain or amend any disclosures with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted and we are not including certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. Terms used but not defined herein are as defined in the 2023 10-K.

CORPORATE GOVERNANCE

Code of Ethics

The AES Code of Conduct (“Code of Conduct”), adopted by the AES Board of Directors, governs the actions of AES employees, including employees of its subsidiaries and affiliates, including the CEO, CFO and Controller of AES Indiana and IPALCO, and the directors of IPALCO. The Ethics and Compliance Department of AES provides training, information, and certification programs for employees of AES and its subsidiaries (including AES Indiana and IPALCO) related to the Code of Conduct. The Ethics and Compliance Department also has programs in place to prevent and detect criminal conduct, promote an organizational culture that encourages ethical behavior and a commitment to compliance with the law, and to monitor and enforce AES policies on corruption, bribery, money laundering and associations with terrorist groups. The Code of Conduct is located in its entirety on the AES website (https://www.aes.com/ethics-compliance). Any person may obtain a copy of the Code of Conduct without charge by making a written request to: Corporate Secretary, IPALCO Enterprises, Inc., One Monument Circle, Indianapolis, IN 46204. If any amendments to, or waivers from, the Code of Conduct are made, in each case relating to the CEO, CFO and Controller of AES Indiana and IPALCO, AES will disclose such amendments or waivers on its website (www.aes.com). Except for such Code of Conduct, the information contained on or accessible through the AES website is not incorporated by reference into this Amendment or the 2023 10-K.

References to AES’ website throughout this Amendment are provided for convenience only and the content on AES’ website does not constitute a part of this Amendment.

Corporate Governance

The Board has not established any committees, including an audit committee, a compensation committee or a nominating committee, or any committee performing similar functions. The functions of those committees are undertaken by the Board. The Board may designate from among its members an executive committee and one or more other committees in the future.

IPALCO’s securities are not quoted on a securities exchange. IPALCO is not required by law, rule, or regulation to have a majority or any portion of the Board be independent. IPALCO is also not required by law, rule, or regulation to establish or maintain an audit committee or other Board committee and thus we do not have an “audit committee financial expert” as defined under applicable SEC rules.

Nomination of Directors

As of April 15, 2024, IPALCO had not effected any material changes to the procedures by which shareholders may recommend nominees to the Board. IPALCO’s Third Amended and Restated Articles of Incorporation and Amended and Restated By-Laws do not provide formal procedures for shareholders to recommend nominees to the Board. Except as described below, the Board has determined that it is in the best position to evaluate IPALCO’s requirements as well as the qualifications of each candidate when the Board considers a nominee for a position on the Board.

AES U.S. Investments, IPALCO and CDPQ are parties to a Shareholders’ Agreement dated February 11, 2015 (the “Shareholders’ Agreement”). The Shareholders’ Agreement provides AES U.S. Investments the right to nominate nine directors of the IPALCO Board and CDPQ the right to nominate two directors to the IPALCO Board. See “Shareholders’ Agreement” in “Item 13. Certain Relationships and Related Transactions, and Director Independence” of this Amendment.

ITEM 11.    EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

The compensation paid to our NEOs in 2023 is set forth in the Summary Compensation Table (2023, 2022 and 2021) (the “Summary Compensation Table”) below. Our NEOs for 2023 are:

•Kenneth J. Zagzebski, President and Chief Executive Officer and Chairman of the Board

•Kristina Lund, Former President and Chief Executive Officer and Chairman of the Board (served until July 21, 2023)

•Ahmed Pasha, Former Vice President and Chief Financial Officer (served in this role all of 2023 until January 1, 2024) and Acting President and Chief Executive Officer (from July 21, 2023 to August 11, 2023)

•Brandi Davis-Handy, President, AES Indiana (since February 28, 2024) and Chief Customer Officer (served in this role all of 2023 and until February 28, 2024)

•Brian Hylander, Vice President, General Counsel and Secretary

•Jeremy Buchanan, Vice President, Human Resources

In this CD&A, explanations of how non-GAAP measures are calculated from the audited financial statements are included under the heading “Non-GAAP Measures.”

Background

AES Family of Companies

In order to better understand our compensation programs for our NEOs, we think that it is helpful to describe how the management of IPALCO is operated within the AES family of companies. IPALCO was acquired by AES in March 2001, is a majority-owned subsidiary of AES U.S. Investments, and has a minority interest holder, CDPQ, as of February 11, 2015. AES Indiana is our primary operating subsidiary. Most of the key members of our management team are employed by other AES companies and perform roles for both IPALCO and other AES entities.

AES manages its business through strategic business units. The AES US Utilities, including IPALCO and AES Indiana, and AES US Generation are part of these strategic business units; however, the US and Utilities is not a legal entity. AES also has an indirectly wholly-owned subsidiary, the Service Company, which was established in late 2013. The Service Company provides services, including operations, accounting, legal, human resources, information technology and other corporate services on behalf of companies that are part of the US and Utilities, including, among other companies, IPALCO and AES Indiana. As a result of this structure, IPALCO and AES Indiana do not directly employ all of the executives responsible for the management of our business. In 2023, our NEOs were all executive officers of one or more of IPALCO, AES Indiana and the Service Company.

The Service Company allocates the costs for services provided based on cost drivers designed to result in fair and equitable allocations pursuant to a Cost Alignment and Allocation Manual (the “CAAM”).

7

As a result, the costs associated with our executive compensation for those officers performing work for other entities are also allocated pursuant to the terms of the CAAM, based on the amount of time that each executive officer devotes to our business as described under “Item 13. Certain Relationships and Related Transactions, and Director Independence - Service Company.” The executive compensation reported in this Amendment reflects the entire compensation paid or awarded to, or earned by, each NEO for their services on behalf of one or more of IPALCO, AES Indiana, the Service Company, AES and other AES affiliated entities and not just the portion of such compensation that is allocated to IPALCO and AES Indiana.

Our Executive Compensation Philosophy and Objectives

Our compensation philosophy is consistent with AES’ compensation philosophy, which emphasizes pay-for-performance. Our compensation philosophy is to provide compensation opportunities to each of our NEOs that are commensurate with his or her position, experience, and scope of responsibilities, to furnish incentives sufficient for each NEO to meet and exceed short-term and long-term corporate objectives and to provide executive compensation and incentives that will attract, motivate, and retain a highly skilled management team.

Consistent with this philosophy and our goal of aligning our executives’ compensation with Company performance, the key features of our executive compensation program include the following:

•Our compensation program allocates a significant portion of each applicable NEO’s total compensation to short- and long-term performance goals. As such, payouts are dependent upon the strategic, financial, and operational performance of AES and the US and Utilities, which includes IPALCO and AES Indiana, and the performance of AES’ stock price;

•Our compensation program is continually reviewed to confirm that it meets our objectives and executive compensation philosophy and remains competitive; and

•We generally do not provide perquisites to our NEOs, with the exception of relocation-related benefits from time to time.

In order to meet these objectives, our total compensation structure includes a mix of short-term compensation, in the form of base salaries and annual cash bonuses, and long-term compensation, in the form of AES equity-based and cash-based performance awards.

Our Compensation Process

The Chief Executive Officer of AES (the “AES CEO”) and the Chief Human Resources Officer of AES (the “AES CHRO”, and together with the AES CEO, the “Executive Compensation Review Team”) have the responsibility of reviewing and administering compensation for the officers of the Service Company, IPALCO, and AES Indiana, including our NEOs. The Executive Compensation Review Team, with assistance from the US and Utilities human resources team, determines the appropriate pay grade for our NEOs at the date of hire based upon each individual’s position, responsibilities, skills and experience, and reassesses each NEO’s position within the applicable pay grade at the end of each year.

The pay grades comprising our compensation framework are established by the AES human resources team and include specific base salary ranges and short-term bonus and long-term compensation targets for each pay grade. The AES human resources team uses survey data from Willis Towers Watson and other sources in evaluating the overall pay structure at a high level. The structure is compared annually to market data from various sources, including Willis Towers Watson’s survey data, to assess the external competitiveness of the base salary ranges and incentive targets for the pay grades. During our performance review cycle, the Executive Compensation Review Team measures the specific amount and resulting incentive compensation for each of our NEOs based on (i) the operational and financial performance of the US and Utilities and AES and (ii) the NEO’s target opportunity for his or her applicable pay grade.

8

Awards of short-term compensation are made in the form of annual cash bonuses to our NEOs under the AES Performance Incentive Plan (the “PI Plan”) and are determined by the Executive Compensation Review Team in the first quarter. Awards of long-term compensation are made to our NEOs under the AES 2003 Long Term Compensation Plan, as amended and restated (the “LTC Plan”) and are determined by the Board of Directors of AES based upon the recommendations of the Executive Compensation Review Team made in the last quarter of each year as described below.

The use and weight of cash versus non-cash, fixed versus variable, and short- versus long-term components of executive compensation is generally dictated by the applicable pay grade for each NEO. As we are not subject to the federal proxy rules, we are not required to hold a shareholder advisory vote on our executive compensation, or a “Say-on-Pay” vote, or the related “Say-on-Frequency” vote.

Elements of Compensation

The fundamental elements of our compensation program are:

◦base salary;

◦performance-based, short-term annual cash bonuses under the PI Plan;

◦cash-based incentive awards granted under the LTC Plan;

◦equity incentive awards granted under the LTC Plan in AES equity, for which there is a public market; and

◦other broad-based benefits, such as retirement and health and welfare benefits.

The pay grades comprising our compensation framework provide allocations of cash versus equity compensation and short- and long-term compensation. The Executive Compensation Review Team sets each individual element of total compensation within the parameters of the pay grade applicable to each particular NEO, as set forth below.

2023 Compensation Determinations

Base Salary

Base salary represents the “fixed” component of our executive compensation program for our NEOs. We provide our NEOs with base salaries in order to provide fixed cash compensation that is competitive and reflects experience, responsibility, and expertise. Base salaries are reviewed annually in the last quarter of each year and are adjusted as appropriate within the base salary ranges of the applicable pay grade. Base salary is also reviewed for an executive officer if there is a promotion or a newly appointed executive officer. Internal company salary guidance regarding annual base pay adjustments is also taken into consideration, and adjustments to base salaries are made when needed to reflect individual performance and retention considerations, and to address internal equity. Please see the “Salary” column of the Summary Compensation Table below for the base salary amounts paid to our NEOs for the years indicated.

2023 Performance Incentive Plan Payouts

In addition to base salaries, in 2023 we provided performance-based, annual cash bonuses under the PI Plan. Each pay grade has a corresponding PI Plan target opportunity, which is assessed annually. Each NEO’s opportunity corresponds to the opportunity applicable to his or her pay grade. These awards are paid based on the achievement of AES and US and Utilities measures in strategic performance categories described in the tables below, which were established in early 2023. The PI Plan is structured in a manner that provides our NEOs with a direct incentive to achieve such objectives. Payout formulas under the PI Plan for each of our NEOs are based on the business functions and responsibilities for the NEO within the organization. For Mr. Zagzebski, the award is based on the achievement of the AES Corporate goals. For Mr. Buchanan and Mr. Hylander, the award is 25% based on the achievement of the AES Corporate goals and 75% based on the achievement of the US and Utilities goals with equal weight given to: (i) the achievement of the AES US Utilities goals, which includes IPALCO and AES Indiana and

9

their Ohio sister companies, DPL and AES Ohio, and (ii) the achievement of AES US Generation goals, which includes other AES generation companies in the US. For Ms. Davis-Handy, the award is based 25% on the achievement of AES Corporate goals and 75% on the achievement of the AES US Utilities goals. Ms. Lund and Mr. Pasha forfeited the right to receive a 2023 PI Plan payout when they resigned from AES. Ms. Lund would have been eligible for an award based 50% on the achievement of AES Corporate goals and 50% on the achievement of AES US Utilities goals, and Mr. Pasha would have been eligible for an award based 25% on the achievement of AES Corporate goals and 75% on the achievement of US and Utilities goals with equal weight given to AES US Utilities goals and AES US Generation goals.

In 2023, payments under the PI Plan were determined based on the AES and the US and Utilities 2023 performance measures as described in the tables below. The AES Corporate performance measures were approved by the AES Compensation Committee of its Board of Directors (the “AES Compensation Committee”). Performance measures for the US and Utilities were based upon the Executive Compensation Review Team’s and US and Utilities leadership’s business goals for AES US Generation and the AES US Utilities, including IPALCO and AES Indiana, for 2023. The Executive Compensation Review Team approved performance measures and objectives across all categories that it considered to be challenging, but achievable, with US and Utilities leadership and CDPQ providing input with regard to objectives applicable to IPALCO and AES Indiana. Targets for the 2023 financial measures for AES and the US and Utilities were based on the 2023 financial budget as well as strategic objectives. Individual awards are paid out at 0-200% of the target applicable to each pay grade depending on scores achieved relative to the performance measures.

See “Non-GAAP Measures” below for reconciliations of Adjusted EPS, Adjusted EBITDA and Parent Free Cash Flow to the most directly comparable GAAP measures, as applicable.

3Assuming the threshold requirement for the Green Growth and COD metrics are met, the score ranges from 50% to 200%: 50% score corresponds to actual results at 80% of the target goal, and a 200% score corresponds to actual results at 120% of the target goal.

4The 200% award in this category is based on the significant achievements AES made towards progressing Green Hydrogen as a business line. The following paragraph includes additional details.

The AES Compensation Committee approved a performance assessment of 200% for the New Business Models metric to recognize AES’ new business achievements and significant advancements. Some key achievements include:

• AES was part of a group that was awarded two of the seven Regional Clean Hydrogen Hubs by the US Department of Energy (“DOE”).

◦ AES was part of a group that was awarded the Alliance for Renewable Clean Energy System Hub in California, and the other group was awarded the HyVelocity Hub in the Gulf Coast of Texas and Louisiana, both of which were allocated up to $1.2 billion in DOE funding.

◦ AES’s green hydrogen projects have been designed to meet even the most stringent (hourly) matching requirements for renewable power.

• Among the first in the industry to use transferability of tax credits for renewable energy projects, as authorized under the Inflation Reduction Act.

• Motor, a company majority-owned and incubated by AES that partners with utilities to promote electric vehicle adoption, raised $7M of external funding and secured its first non-AES utility customer in Green Mountain Power.

2023 Discretionary Cash Bonuses

In connection with the performance of the US and Utilities and the individual contributions of the NEOs in 2023, the Executive Compensation Review Team determined it was appropriate to grant certain of the NEOs discretionary cash bonuses in the amounts as set forth in the table below. These discretionary cash bonuses were paid to the NEOs in the first quarter of 2024.

NEO	2023 Discretionary Cash Bonus Amount ($)
Kenneth J. Zagzebski	$132,629
Brandi Davis-Handy	$24,720
Jeremy Buchanan	$25,520

Long Term Compensation Elements

AES grants a mix of cash- and equity-based awards under the LTC Plan. These awards help the Company to attract and retain key individuals who are critical to the success of our business and align the interests of our NEOs with those of AES’ stockholders over the long term. Grants to our NEOs under the LTC Plan, whether in cash or stock, vest ratably over a three-year period or based on a cumulative three-year performance period and are determined based on a percentage of the individual’s base salary. The mix of awards under the LTC Plan for each of our NEOs is based on the business functions and responsibilities for the NEO within the organization. In the first quarter of 2023, our NEOs other than Ms. Lund received awards as follows: 50% in the form of cash-settled Performance Units (“PUs”) and 50% in the form of AES stock-settled Restricted Stock Units (“RSUs”). Ms. Lund received awards as follows: 50% in the form of cash-settled Performance Cash Units (“PCUs”), 30% in the form of AES stock-settled Performance Stock Units (“PSUs”), and 20% in the form of AES stock-settled RSUs. In connection with Ms. Lund’s and Mr. Pasha’s resignations from AES, they each forfeited their respective 2023 LTC Plan awards. For a description of 2023 PCU, PSU and RSU awards granted to Ms. Lund that she forfeited upon her resignation from AES, see AES’ proxy statement filed on March 14, 2024.

Performance Units (PUs)

PUs represent the right to receive a cash-based payment subject to performance- and service-based vesting conditions. PUs granted in 2023 are eligible to vest subject to AES’ three-year cumulative Parent Free Cash Flow performance. Parent Free Cash Flow is a strategically important non-GAAP financial metric to AES as it reflects the ability of AES’ businesses to generate cash for AES’ investors that can be either reinvested in the business or paid to investors through dividends, and additionally is a key metric for ratings agencies. A description of how Parent Free Cash Flow is calculated from AES’ audited financial statements is described in “Non-GAAP Measures” below.

The Parent Free Cash Flow target is set for the three-year performance period and is subject to pre-defined, objective adjustments during the three-year performance period based on changes to AES’ portfolio, such as an asset divestiture or sale of a portion of equity in a subsidiary.

The value of each PU is equal to $1.00, and the number of PUs that vest depends upon the level of Parent Free Cash Flow achieved over the three-year measurement period. If a threshold level of Parent Free Cash Flow is achieved, a percentage of the PUs vest and are settled in cash in the calendar year that immediately follows the end of the performance period.

The following table illustrates the vesting percentage at each Parent Free Cash Flow level for targets set for the 2023-2025 performance period:

Performance Level	Vesting Percentage
Below 90% of Performance Target	0%
Equal to 90% of Performance Target	50%
Equal to 100% of Performance Target	100%
Equal to or Greater than 110% of Performance Target	200%

Between the Parent Free Cash Flow levels listed in the above table, straight-line interpolation is used to determine the vesting percentage for the award. The ability to earn PUs is also generally subject to the continued employment of the NEO. The AES Compensation Committee approved a Parent Free Cash Flow target for the 2023 PUs that is believed by the AES Compensation Committee to be challenging, but achievable and requires growth over the prior year’s goals.

Restricted Stock Units (RSUs)

RSUs represent the right to receive a single share of AES Common Stock subject to service-based vesting conditions. AES grants RSUs to assist in retaining executives and also to increase their ownership of AES Common Stock, which further aligns executives’ interests with those of AES stockholders. RSUs generally vest based on continued service with AES and its subsidiaries in three equal installments, beginning on the first anniversary of the grant date.

2023 Long Term Compensation Grants

As in previous years, the allocation of long-term compensation components granted in 2023 was based on a review of market practice conducted by AES and is aligned with the objective of fostering the long-term corporate performance of AES, as our parent company, and rewarding individual performance.

15

The following table sets forth the aggregate target grant value for the 2023 LTC Plan awards made to our NEOs.

	February 2023 Long-Term Compensation Aggregate Target Grant Value
Name	As % of Base Salary(1)	Dollar Amount
Kenneth J. Zagzebski	100%		$463,619
Kristina Lund (2)	152%		$636,527
Ahmed Pasha(2)	80%		$319,123
Brandi Davis-Handy	50%		$129,996
Brian Hylander	50%		$140,010
Jeremy Buchanan	50%		$124,990

(1)Based on salary as of December 31, 2022.

(2) In connection with Ms. Lund’s and Mr. Pasha’s resignations from AES, they each forfeited their respective 2023 LTC Plan awards.

As discussed under “Our Compensation Process” above, grant values are generally guided by each NEO’s applicable AES pay grade (and, in the case of the RSUs, are rounded down to the nearest whole share at the time of grant). Further detail on all long-term compensation grants to our NEOs can be found in the Summary Compensation Table (2023, 2022, and 2021) and the Grants of Plan-Based Awards (2023) Table in this Amendment. For Ms. Lund, the value in the table above differs from the Stock Awards column in the Summary Compensation Table (2023, 2022, and 2021) because the PCUs contain a market condition which results in a fair market value, for financial accounting purposes, that differs from the $1 per unit value the Company uses to determine the grant.

Prior Year PUs Vesting in 2023

All of the NEOs, with the exception of Mr. Pasha (who was awarded a different mix of awards under the LTC Plan in 2021), received a grant of PUs in February 2021 for the January 1, 2021 through December 31, 2023 performance period (the “2021-2023 PUs”). For the 2021-2023 PUs, performance was based on AES’ cumulative Parent Free Cash Flow performance during the 2021-2023 period. See “Non-GAAP Measures” for a reconciliation of Parent Free Cash Flow to the most directly comparable GAAP measure.

The 2021-2023 PUs paid out at 153.68% of target based on AES’ actual cumulative Parent Free Cash Flow results of $2,748M during the three-year performance period, which was 105.37% of the target cumulative Parent Free Cash Flow. As described above for the 2023 PUs and as previously disclosed, the performance scale for these awards was 100% vesting for performance equal to 100% of target, 50% vesting for performance equal to 90% of target, and 200% vesting for performance equal to or greater than 110% of target. The actual performance payout level is derived using straight-line interpolation: for every one percentage point performance is above the target goal, the payout is increased by approximately ten percentage points. The payouts for these awards for each NEO are shown in the following table:

NEO	Target Number of Performance Units	% of Target Value Based on Parent Free Cash Flow		Final Vested Value
Kenneth J. Zagzebski	222,106	153.68	%	$341,333
Kristina Lund	166,256	—	%	—
Ahmed Pasha	—	—	%	—
Brandi Davis-Handy	44,000	153.68	%	$67,619
Brian Hylander	43,184	153.68	%	$66,365
Jeremy Buchanan	32,552	153.68	%	$50,026

* In connection with her resignation from AES, Ms. Lund forfeited the entirety of her 2021-2023 PU awards.

16

Further details regarding the 2021-2023 PU payouts can be found in the Summary Compensation Table (2023, 2022, and 2021) in this Amendment.

Other Relevant Compensation Elements and Policies

Perquisites

We generally do not provide any perquisites to our NEOs, with the exception of relocation-related benefits from time to time.

Retirement and Other Broad-Based Employee Benefits

Our NEOs, as well as our other employees, are eligible for the following benefits: participation in a defined contribution (401(k)) plan, group health insurance (including medical, dental, and vision), long- and short-term disability insurance, basic life insurance and paid time off. Mr. Hylander previously participated in The Dayton Power and Light Company Retirement Income Plan (the “DP&L Retirement Income Plan”). Our NEOs are eligible to participate in the AES Restoration Supplemental Retirement Plan (the “RSRP”), a nonqualified deferred compensation plan, which is intended to restore benefits that are limited under our broad-based retirement plans due to statutory limits imposed by the United States Internal Revenue Code (the “Code”). The RSRP’s objective is consistent with our philosophy to provide competitive levels of retirement benefits and to retain talented executives. The RSRP does not contain any enhanced or special benefit formulas for our NEOs. Contributions to the RSRP made in 2023 are included in the All Other Compensation column of the Summary Compensation Table (2023, 2022 and 2021) in this Amendment. Additional information regarding the RSRP is contained in the “Narrative Disclosure Relating to the Non-Qualified Deferred Compensation Table” in this Amendment.

Severance and Change in Control Arrangements

AES maintains certain severance and change in control arrangements, including The AES Corporation Amended and Restated Severance Plan (the “Severance Plan”) and change-in-control provisions in the long-term compensation award agreements. Upon a change-in-control of AES, the unvested portion of all outstanding awards will vest only upon a double-trigger (at target performance levels for performance awards). The double-trigger only allows for vesting if a qualifying termination occurs in connection with the change-in-control. All unvested, outstanding awards include a double-trigger vesting provision. In addition, all NEOs are entitled to payments and benefits under the Severance Plan, in the event of qualifying terminations of employment, both related and unrelated to a change in control, as provided in the Benefits Schedule included therein. Finally, upon a termination of service (other than by reason of death) prior to reaching retirement eligibility, or in the event of a change-in-control, participants’ account balances in the RSRP (described in the Nonqualified Deferred Compensation (2023) Table below) would be paid in a lump sum. Please see “Potential Payments Upon Termination or Change in Control (2023)” below for a more detailed summary of these payments and benefits.

Employment Agreements and Other Arrangements

Our NEOs do not have any employment agreements or other arrangements, except as disclosed herein or in “Potential Payments Upon Termination or Change in Control (2023).”

Prohibition Against Hedging and Pledging

AES’ Securities Trading Policy prohibits AES’ and its subsidiaries’ employees (including officers) and directors from engaging in hedging transactions with respect to AES’ equity securities including, without limitation, the purchase of financial instruments (including prepaid variable forward contracts, equity swaps, collars, and exchange funds), or otherwise engaging in transactions, that hedge or speculate, or are designed to hedge or speculate, on any change in the market value of AES’ equity securities. AES

17

additionally prohibits AES’ and its subsidiaries’ employees (including officers) and directors from pledging AES securities in any circumstance, including by purchasing AES securities on margin or by holding AES securities in a margin account.

Non-GAAP Measures

In this CD&A, we reference certain non-GAAP measures, including Adjusted EPS, Adjusted Pre-Tax Contribution (“Adjusted PTC”), Subsidiary Distributions, and Parent Free Cash Flow. These measures are described below.

Adjusted Earnings Per Share (Adjusted EPS).

AES defines Adjusted EPS as diluted earnings per share from continuing operations excluding gains or losses of both consolidated entities and entities accounted for under the equity method due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures, the tax impact from the repatriation of sales proceeds, and gains and losses recognized at commencement of sales-type leases; (d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; and (f) net gains at Angamos, one of AES’ businesses in its Energy Infrastructure strategic business unit (“SBU”), associated with the early contract terminations with Minera Escondida and Minera Spence.

The GAAP measure most comparable to Adjusted EPS is diluted earnings per share from continuing operations. AES believes that Adjusted EPS better reflects the underlying business performance of the company and is considered in AES’ internal evaluation of financial performance. Factors in this determination include the variability due to unrealized gains or losses related to derivative transactions or equity securities remeasurement, unrealized foreign currency gains or losses, losses due to impairments, strategic decisions to dispose of or acquire business interests or retire debt, and the non-recurring nature of the impact of the early contract terminations at Angamos, which affect results in a given period or periods. Adjusted EPS should not be construed as an alternative to diluted earnings per share from continuing operations, which is determined in accordance with GAAP.

5 Amount primarily relates to losses incurred at AES Andes due to early retirement of debt of $46 million, or $0.07 per share, and loss on early retirement of debt at AES Hispanola Holdings BV of $10 million, or $0.01 per share.

6 Amount primarily relates to income tax benefits associated with the asset impairments at Warrior Run of $46 million, or $0.06 per share, at the Norgener coal-fired plant in Chile of $37 million, or $0.05 per share, at New York Wind of $32 million, or $0.05 per share, at TEG and TEP of $27 million, or $0.04 per share, and at AES Clean Energy development projects of $26 million, or $0.04 per share; income tax benefits associated with the recognition of unrealized losses due to the termination of a PPA of $17 million, or $0.02 per share; income tax benefits associated with losses incurred at AES Andes due to early retirement of debt of $13 million, or $0.02 per share; income tax benefits associated with early plant closure costs in Chile of $10 million, or $0.01 per share; and income tax benefits associated with unrealized foreign currency losses at AES Andes of $7 million, or $0.01 per share; partially offset by income tax expense associated with the gain on sale of Fluence shares of $31 million, or $0.04 per share.

Adjusted EBITDA .

AES defines EBITDA as earnings before interest income and expense, taxes, depreciation, and amortization. AES defines Adjusted EBITDA as EBITDA adjusted for the impact of noncontrolling interest and interest, taxes, depreciation, and amortization of our equity affiliates, adding back interest income recognized under service concession arrangements, and excluding gains or losses of both consolidated entities and entities accounted for under the equity method due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures, and gains and losses recognized at commencement of sales-type leases; (d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; and (f) net gains at Angamos, one of AES’ businesses in the Energy Infrastructure SBU, associated with the early contract terminations with Minera Escondida and Minera Spence.

In addition to the revenue and cost of sales reflected in Operating Margin, Adjusted EBITDA includes the other components of AES’ Consolidated Statement of Operations, such as general and administrative expenses in Corporate and Other as well as business development costs, other expense

19

and other income, realized foreign currency transaction gains and losses, and net equity in earnings of affiliates.

The GAAP measure most comparable to Adjusted EBITDA is Net income. AES believes that Adjusted EBITDA better reflects the underlying business performance of the company. Adjusted EBITDA is the most relevant measure considered in AES’ internal evaluation of the financial performance of its segments. Factors in this determination include the variability due to unrealized gains or losses related to derivative transactions or equity securities remeasurement, unrealized foreign currency gains or losses, losses due to impairments, strategic decisions to dispose of or acquire business interests or retire debt, the non-recurring nature of the impact of the early contract terminations at Angamos, and the variability of allocations of earnings to tax equity investors, which affect results in a given period or periods. In addition, each of these metrics represent the business performance of AES before the application of statutory income tax rates and tax adjustments, including the effects of tax planning, corresponding to the various jurisdictions in which AES operates.

Adjusted EBITDA should not be construed as an alternative to Net income, which is determined in accordance with GAAP.

Parent Free Cash Flow.

Reconciliation of 2023 and 2021-2023 AES Parent Free Cash Flow1

Other	$	—	$	(1)
Parent Free Cash Flow1	$	1,003	$	2,748

1 Parent Free Cash Flow (a non-GAAP financial measure that was used as a performance metric for both the 2023 Performance Incentive Plan awards and the 2021 PU awards) should not be construed as an alternative to Consolidated Net Cash Provided by Operating Activities, which is determined in accordance with U.S. GAAP. Parent Free Cash Flow is the primary, recurring source of cash that is available for use by the Parent Company (or AES). Parent Free Cash Flow is equal to Subsidiary Distributions less cash used for interest costs, development, general and administrative activities, and tax payments by the Parent Company. AES Management uses Parent Free Cash Flow to determine the cash available to pay dividends, repay recourse debt, make equity investments, fund share buybacks, pay Parent Company hedging costs and make foreign exchange settlements. AES believes that Parent Free Cash Flow is useful to investors because it better reflects the Parent Company’s cash available to make growth investments, pay shareholder dividends, and make principal payments on recourse debt. Factors in this determination include availability of subsidiary distributions to the Parent Company and the Company’s investment plan.

2 Refer to Net Cash Provided by Operating Activities at the Parent Company as reported at Part IV—Item 15—Schedule– 1 - Condensed Financial Information of AES’ Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on February 26, 2024 (the “AES 2023 10-K”) (“Schedule 1”).

3 Subsidiary distributions received by Qualified Holding Companies (“QHCs”) excluded from Schedule 1. Subsidiary Distributions should not be construed as an alternative to Consolidated Net Cash Provided by Operating Activities for AES, which is determined in accordance with US GAAP. Subsidiary Distributions are important to the Parent Company because the Parent Company is a holding company that does not derive any significant direct revenues from its own activities but instead relies on its subsidiaries’ business activities and the resultant distributions to fund the debt service, investment and other cash needs of the holding company. The reconciliation of the difference between the Subsidiary Distributions and Consolidated Net Cash Provided by Operating Activities consists of cash generated from operating activities that is retained at the subsidiaries for a variety of reasons which are both discretionary and non-discretionary in nature. These factors include, but are not limited to, retention of cash to fund capital expenditures at the subsidiary, cash retention associated with non-recourse debt covenant restrictions and related debt service requirements at the subsidiaries, retention of cash related to sufficiency of local GAAP statutory retained earnings at the subsidiaries, retention of cash for working capital needs at the subsidiaries, and other similar timing differences between when the cash is generated at the subsidiaries and when it reaches the Parent Company and related holding companies.

4 Subsidiary distributions that originated from the results of operations of an underlying investee but were classified as investing activities when received by the relevant holding company included in Schedule 1.

5 Net cash payments for AES-funded SBU overhead, business development, taxes, transaction costs, and capitalized interest that are classified as investing activities or excluded from Schedule 1.

Adjusted Pre-Tax Contribution (“Adjusted PTC”). Adjusted PTC is pre-tax income from continuing operations attributable to AES excluding gains or losses of the consolidated entity due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures, and gains and losses recognized at commencement of sales-type leases; (d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; and (f) net gains at Angamos, one of AES’ businesses in the Energy Infrastructure SBU, associated with the early contract terminations with Minera Escondida and Minera Spence. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities.

Subsidiary Distributions. Subsidiary Distributions for a strategic business unit are the sum of the following amounts (a) dividends paid to the borrower by its subsidiaries during such period; (b) consulting and management fees paid to the borrower for such period; (c) tax sharing payments made to the borrower during such period; (d) interest and other distributions paid to the borrower during such period with respect to cash and other temporary cash investments of the borrower (other than with respect to amounts on deposit in the Revolving L/C Cash Collateral Account); (e) cash payments made to the

21

borrower in respect of foreign exchange hedge agreements or other foreign exchange activities entered into by the borrower on behalf of any of its subsidiaries; and (f) other cash payments made to the borrower by its subsidiaries other than (i) returns of invested capital; (ii) payments of the principal of debt of any such subsidiary to the borrower and (iii) payments in an amount equal to the aggregate amount released from debt service reserve accounts upon the issuance of letters of credit for the account of the borrower and the benefit of the beneficiaries of such accounts.

Compensation Risk

We believe that the applicable compensation programs and policies are designed and administered with the appropriate mix of compensation elements and balance current and long-term performance objectives, cash and equity compensation, and risks and rewards associated with our executives’ roles. As a result, we believe that the risks arising from our employee compensation program are not reasonably likely to have a material adverse effect on the Company.

(1)    The compensation disclosed in this table represents the full amount of compensation paid to each NEO and is not limited to the portion of each NEOs compensation allocated to and paid by IPALCO.

(2)    The base salary earned by each NEO during fiscal years 2023, 2022, or 2021, as applicable.

(3)    Aggregate grant date fair value of PSUs and PCUs granted to Ms. Lund and RSUs granted to all NEOs in the year, which are computed in accordance with Financial Accounting Standards Board (“FASB”), Accounting Standards Codification (“ASC”) Topic 718, “Compensation – Stock Compensation” (“FASB ASC Topic 718”), disregarding any estimate of forfeitures related to service-based vesting conditions and assuming a target level of performance. A discussion of the relevant assumptions made in the valuation may be found in the financial statements, footnotes to financial statements (footnote 19), or Management’s Discussion & Analysis, as appropriate, contained in AES’ Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on February 26, 2024 (the “AES 2023 10-K”), which also includes information for 2022 and 2021 The 2023 amounts for Ms. Lund reflect the value of the PSUs, PCUs and RSUs at target. Assuming (i) the maximum market and financial performance conditions are achieved, (ii) in the case of PSUs, the share price at grant, and (iii) in the case of RSUs, an adjustment percentage of +15.0%, the maximum values of PSUs, PCUs, and RSUs granted to Ms. Lund in fiscal year 2023, and payable upon completion of the 2023-2025 performance period is $1,164,842 (PSUs - $381,927; PCUs - $636,510; and RSUs - $146,405). As a result of her resignation from AES in July 2023, Ms. Lund forfeited all of her unvested equity awards. Similarly, in connection with his resignation from AES in January 2024, Mr. Pasha forfeited his 2023 RSU award..

(4)    The value of all non-equity incentive plan awards earned during the 2023 fiscal year and paid in 2024, which includes awards earned under the PI Plan (our annual incentive plan) and awards earned for the three-year performance period ended December 31, 2023 for our cash-based 2021-2023 PUs granted under the LTC Plan.

(1) Included in this item are:

a. Grants of RSUs made to all NEOs that vest in three equal installments on the first three anniversaries of the grant date. These awards include:

(i) An RSU grant made on February 19, 2021 for which the final installment vested on February 19, 2024. For Mr. Pasha, a portion of this award was subject to a +/-15.0% modifier based on ESG goals. The full portion of the final installment is included.

(ii) An RSU grant made on February 24, 2022 for which the second installment vested on February 24, 2024, and the third installment will vest on February 24, 2025. For Mr. Pasha, a portion of this award is subject to a +/-15.0% modifier based on ESG goals. This portion of the award is shown in the “Equity Incentive Plan Awards: Number of Unearned Shares, Units or Other Rights That Have Not Vested” column and described in footnote 4 below.

(iii) An RSU grant made on February 24, 2023 for which the first installment vested on February 24, 2024, and the remaining two installments will vest on February 24, 2025 and February 24, 2026, respectively.

b. Grants of RSUs made to Mr. Pasha on November 19, 2021 that vest in four installments for which 10% vested on November 19, 2022, 15% vested on November 19, 2023, 25% would have vested on November 19, 2024, and 50% would have vested on November 19, 2025.

(2) Included in this item are PSUs for Mr. Pasha granted on February 24, 2022 that would have vested if earned, upon final certification of results in the first quarter of 2025, based on the financial performance condition of AES’ three-year cumulative Parent

27

Free Cash Flow, subject to AES Compensation Committee approval, and three-year service conditions (but only when and to the extent financial performance conditions are met). Based on AES’ performance through the end of fiscal year 2023 relative to the performance criteria, our current period to-date results for the 2022-2024 ongoing performance period is between target and maximum, and thus the maximum number of PSUs granted in 2022 are included above.

(3) Included in this item are PCUs granted to Mr. Pasha on February 24, 2022 which would have vested if earned, on February 24, 2025 based AES’ three-year cumulative Total Stockholder Return relative to peer indices and three-year service conditions (but only when and to the extent the market performance conditions are met). Based on AES’ performance through the end of fiscal year 2023 relative to the performance criteria, our current period to-date results for the 2022-2024 ongoing performance period is between threshold and target and thus the target number of PCUs granted in 2022 are included above.

(4) This item represents a portion of an RSU grant made to Mr. Pasha on February 24, 2022 for which the second installment would have vested on February 24, 2024, and the remaining installment would have vested on February 24, 2025. Portions of these awards that vest solely based on continued service with the Company are shown in the “Number of Shares or Units of Stock That Have Not Vested” column and described in footnote 2 above for Mr. Pasha. The portions of the awards shown in this column are subject to a +/-15.0% modifier of the target number of restricted stock units comprising the full award based on ESG goals. Based on AES’ performance through the end of the fiscal years relative to the ESG goals, our current period to-date results for the 2022- 2024 ongoing performance period is between threshold and target and thus the target numbers of RSUs granted in 2022 and subject to the +/-15.0% modifier is included above.

(5) In connection with Ms. Lund’s resignation from AES in July 2023, she forfeited all of her unvested equity at the time (including her 2023 LTC Plan awards). Similarly, in connection with Mr. Pasha’s resignation from AES in January 2024, he forfeited all of his unvested equity at the time.

For Mr. Hylander, the pension value increased from December 31, 2022 to December 31, 2023 due to the decrease in discount rate (27 basis points).

Employee Retirement Plans

The DP&L Retirement Income Plan

The DP&L Retirement Income Plan is a qualified defined benefit plan that provides retirement benefits to employees of DP&L and its affiliates who are participating employers who meet the participation requirements. DP&L is a sister company to IPALCO and NEOs may receive benefits under DP&L plans if they were previously employed by DP&L. Mr. Hylander was eligible to participate in the DP&L Retirement Income Plan from 2009 to 2012 and has a frozen benefit as of 2012. The DP&L Retirement Income Plan covers both union (unit) and nonunion (management) employees. Plan provisions differ by union, management pre-2011 hires (Legacy), and management post-2010 hires. Mr. Hylander is in the management pre-2011 hires category. Mr. Hylander is not currently eligible for early retirement benefits under the DP&L Retirement Income Plan.

Management - pre-2011 hires. Participants must be at least 21 years old and must have completed at least one year of service to be eligible for the DP&L Retirement Income Plan. Participants earn a year of service for each plan year during which they work 1,000 hours beginning with the plan year which includes their participation date. In general, employees receive pension benefits in an amount equal to (a) 1.25% of the average of the employee’s highest three consecutive annual base salaries for the five years immediately preceding the employee’s termination of employment, plus 0.45% of such average pay in excess of the employee’s 35-year average of Social Security wages, multiplied by (b) the employee’s years of service (not exceeding 30 years). Generally, an employee’s normal pension retirement benefits are fully available on his or her 65th birthday. If an employee is no longer employed by a participating employer prior to vesting in the DP&L Retirement Income Plan (five years), the employee forfeits his or her pension benefits. Early retirement benefits are available to employees at any time once they reach age 55 and have completed 10 years of vesting service. However, if pension payments start before age 62, the monthly benefit is reduced by 3/12% for each month before age 62. Participants retiring early receive an additional $187.50 per month until age 65. Generally, pension benefits under the DP&L Retirement Income Plan are paid in monthly installments upon retirement; however, such benefits may be paid in a lump sum depending on the amount of pension benefits available to the employee. Employees have a right to choose a surviving spouse benefit option. If this option is chosen, pension benefits to the employee are reduced.

Narrative Disclosure Relating to the Nonqualified Deferred Compensation Table

The AES Corporation Restoration Supplemental Retirement Plan (RSRP)

The Code places statutory limits on the amount that participants, such as our NEOs, can contribute to The AES Corporation Retirement Savings Plan (the “AES 401(k) Plan”). As a result of these regulations, matching contributions to the AES 401(k) Plan accounts of certain of our NEOs who participated in that plan in fiscal year 2023 were limited. To address the fact that participant and company contributions are restricted by the statutory limits imposed by the Code, our NEOs and other highly compensated employees are eligible to participate in the RSRP, which is designed primarily to restore benefits limited under our broad-based retirement plans due to statutory limits imposed by the Code.

Individuals who participate in the RSRP may defer up to 80% of their base salary and up to 100% of their annual bonus under the RSRP. AES provides a matching contribution to the RSRP for individuals who actively defer and who are also subject to statutory limits.

AES may maintain up to four separate deferral accounts for participants in the RSRP, each of which may have a different distribution date and a different distribution option. A participant in the RSRP may elect to have distributions made in a lump-sum payment or annually over a period of two to fifteen years. All RSRP distributions are made in cash.

Under the RSRP, individuals have the ability to select from a list of hypothetical investments. The investment options are functionally equivalent to the investments made available to all participants in the AES 401(k) Plan. Individuals may change their hypothetical investments within the time periods that are permitted by the AES Compensation Committee, provided that they are entitled to change such designations at least quarterly.

Earnings or losses are credited to the deferral accounts by the amount that would have been earned or lost if the amounts were actually invested.

Individual RSRP account balances are always 100% vested.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL (2023)

The following table contains estimated payments and benefits to each of the NEOs in connection with a termination of employment, both related and unrelated to a change in control, or a change in control of AES. The following amounts assume that a termination or change in control of AES occurred on December 31, 2023, and, where applicable, uses the closing price per share of AES Common Stock of $19.25 (as reported on the NYSE on December 29, 2023). None of the applicable NEOs would be entitled to compensation upon a change in control of IPALCO.

For each applicable NEO, the payments and benefits detailed in the table below are in addition to any payments and benefits under our plans and arrangements that are offered or provided generally to all salaried employees on a non-discriminatory basis and any accumulated or accrued vested benefits for each NEO, including those set forth in the Pension Benefits (2023).

(1)In connection with Ms. Lunds's resignation from AES on July 21, 2023, she did not receive any cash payments or continued benefits, and she forfeited all of her unvested equity and her right to receive any 2023 PI Plan payout. Similarly, Mr. Pasha resigned from AES on January 1, 2024, and did not receive any cash payments or continued benefits, and he forfeited all of his unvested equity.

(2)In addition to the amounts reflected in the above table, a pro rata bonus, to the extent earned, would be payable to Mr. Zagzebski, Mr. Pasha and Ms. Davis-Handy upon a termination without cause or a qualifying termination following a change in control. Pro rata bonus amounts are not included in the above table because, as of December 31, 2023, the service and performance conditions under AES’ 2023 PI Plan would have been satisfied, so such amounts would be paid irrespective of whether a termination or change in control occurs.

(3)Accelerated vesting of LTC Plan awards includes:

•The value of outstanding RSUs granted in February 2021, 2022 and 2023 (at the target payout level for RSUs with a performance feature);

•For Mr. Pasha the value of unvested PSUs granted in February 2022 at the target payout level;

•The value of unvested PUs granted in February 2022 and 2023 at the target payout level; and

•For Mr. Pasha the value of PCUs granted in February 2022 at the target payout level.

(4)    Upon a termination without cause or a qualifying termination following a change in control, the NEO may receive continued medical, dental and vision benefits. The value of this benefits continuation is based on the share of premiums paid by the employer on each NEO’s behalf in 2023, based on the coverage in place at the end of December 2023. For the benefit continuation period, each NEO is responsible for paying the portion of premiums previously paid as an employee.

(5)    Upon a termination without cause or a qualifying termination following a change in control, Mr. Zagzebski, Mr. Pasha and Ms. Davis-Handy are eligible for outplacement benefits. The estimated value of this benefit is $25,000.

Additional Information Relating to Potential Payments upon Termination of Employment or

Change in Control

The following narrative outlining our compensatory arrangements with our NEOs is in addition to other summaries of their terms found in the CD&A of this Amendment.

Potential Payments upon Termination under the AES Corporation Severance Plan

The Severance Plan provides for certain payments and benefits to participants upon the Involuntary Termination or Termination for Good Reason of their employment under certain circumstances, including the execution of a release by the participant pursuant to the terms of the Severance Plan. As of December 31, 2023, all of our NEOs were entitled to the benefits provided by the Severance Plan in 2023 and are entitled to the applicable severance payments and benefits set forth on the benefits schedules included therein (except for Ms. Lund who resigned from AES in July 2023). The discussion below relates to the NEOs who were employees on December 31, 2023.

Certain employees, including the NEOs, are eligible for severance benefits, including salary continuation, applicable benefits and severance payments under the Severance Plan if the employee separates from service due to Involuntary Termination or for Good Reason (each as defined below). Benefits under the Severance Plan require a minimum one year of service eligibility, and are not available under the Severance Plan if the individual’s employment is terminated in connection with certain events as set forth in the Severance Plan, including, but not limited to, (a) an employee’s (i) voluntary resignation (other than for Good Reason), (ii) separation from service for Cause (or for reasons that the employer determines would be inconsistent with the purposes of the Severance Plan), or (iii) declining a new job position located within 50 miles of the employee’s current work site, or (b) due to death or disability, the sale of a business, or in connection with a voluntary transfer of employment.

Upon the termination of employment under the above circumstances, Mr. Zagzebski, Mr. Pasha and Ms. Davis-Handy would be entitled to receive the following:

◦Salary continuation payments equal to their annual base salaries, which would be paid over time in accordance company payroll practices and the terms of the Severance Plan;

◦An additional payment equal to a pro rata portion of their annual cash bonuses, to the extent earned, based upon the time they were employed during the year in which their employment terminates, provided that applicable performance conditions are met;

◦In the event that they elect COBRA coverage under the health plan in which they participate, continuation of employer paid premiums for such coverage (for up to 12 months) in an amount equal to that paid for active employees under the same health plan. They would also receive continuation of dental and vision benefit programs, with Mr. Zagzebski, Mr. Pasha and Ms. Davis-Handy paying the same portion of the premiums as were previously paid as an employee;

34

◦They will be provided with outplacement services provided by an independent agency, provided that the benefit is incurred by and may not extend beyond December 31 of the second calendar year following the calendar year in which the termination occurred; and

◦In the event that termination of their employment occurs due to the circumstances described above and within two years after a “change in control,” the amount of their salary continuation payment will be doubled, and the length of the healthcare benefit continuation period will be increased to 18 months.

In the event of a qualifying termination under the Severance Plan, Mr. Hylander and Mr. Buchanan would be entitled to 7-months prorated annual compensation and continuation of health, dental and vision benefits during this 7-month period. Mr. Pasha resigned from AES in January 2024 and did not receive any of the benefits described herein under the Severance Plan.

The obligation to provide these payments and benefits to the NEOs under the Severance Plan would be conditioned upon the execution and delivery of a written release of claims against the Company and AES. At our discretion, the release may also contain such noncompetition, nonsolicitation and nondisclosure provisions as we may consider necessary or appropriate.

Payment of Long-Term Compensation Awards in the Event of Termination or Change in Control as Determined by the Provisions Set Forth in the 2003 Long Term Compensation Plan (for all NEOs)

The vesting of PSUs, PCUs, RSUs and PUs and the ability of our NEOs to exercise or receive payments under those awards changes in the case of (1) termination of a NEO’s employment or (2) as a result of a change in control. The vesting conditions are defined by the provisions set forth in the 2003 LTC Plan as outlined below:

Performance Stock Units, Performance Cash Units, Restricted Stock Units and Performance Units. Except for Ms. Lund, all of our NEOs held RSUs and PUs as of December 31, 2023, and Mr. Pasha also held PSUs and PCUs as of December 31, 2023. If an NEO’s employment is terminated by reason of death or disability prior to the third anniversary of the grant date of a PSU, PCU or RSU, the PSUs (at target), the PCUs (at target) and/or RSUs (at target, in the case of RSUs with a performance feature) will immediately vest and be delivered. If a NEO separates from service prior to the end of a performance period due to death or disability, all PUs will vest on such termination date and a cash amount equal to $1 for each PU generally will be paid to the NEO on such date or as soon as practicable thereafter.

With PSUs, PCUs RSUs and PUs, voluntary termination or termination for cause prior to the end of the three-year performance period will result in the forfeiture of all outstanding units. Involuntary termination allows prorated time-vesting in increments of one-third or two-thirds vesting in the case of PSUs, PCUs and PUs. Under a qualified retirement, which requires approval of the AES Compensation Committee, the NEO must either reach i) 60 years of age and 7 years of service with the Company or an affiliate or ii) at least 57 years of age and at least 10 years of service with the Company or an affiliate, and, if the AES Compensation Committee so approves, such awards will be paid on the original schedule and, in the case of performance awards, subject to performance against the applicable goals of the awards. In the case of Mr. Zagzebski, he has reached both the age and years of service criteria to be eligible for qualified retirement. If he had retired on December 31, 2023, and if the AES Compensation Committee approved a qualified retirement, the aggregate value of his PUs (assuming target performance) and RSUs would have been $823,225.

If a change in control occurs prior to the end of the three-year performance period, outstanding PSUs, (at target), PCUs (at target), RSUs (at target performance, in the case of RSUs with a performance feature) and PUs (at target) will only become fully vested should a double-trigger occur. The double-trigger only allows for vesting if a qualifying termination occurs in connection with the change in control (other than for a qualifying retirement).

35

The AES Corporation Restoration Supplemental Retirement Plan (RSRP)

In the event of a termination of the applicable NEO’s employment (other than by reason of death) prior to reaching retirement eligibility, or, in the event of a change in control (defined in the same manner as the term “change-in-control” in the RSRP described below), the balances of all of the applicable NEO’s deferral accounts under the RSRP will be paid in a lump sum. In the event of such NEO’s death or retirement, the balances in the NEO’s deferral accounts will be paid according to his or her elections if such NEO was 59 1/2 or more years old at the time of his or her death or retirement. In the event of the NEO’s death or retirement before age 59 1/2, the value of the deferral account will be paid in a lump sum.

36

The following definition is provided in the RSRP of the terms used in this description:

“Change-in-Control” means the occurrence of one or more of the following events: (i) any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all, or substantially all, of the assets of AES to any person or group (as that term is used in Section 13(d)(3) of the Exchange Act) of persons; (ii) a person or group (as so defined) of persons (other than AES Management on the date of the adoption of the RSRP or their affiliates) shall have become the beneficial owner of more than 35% of the outstanding voting stock of AES; or (iii) during any one-year period, individuals who at the beginning of such period constitute the Board of AES (together with any new Director whose election or nomination was approved by a majority of the Directors then in office who were either Directors at the beginning of such period or who were previously so approved, but excluding under all circumstances any such new Director whose initial assumption of office occurs as a result of an actual or threatened election contest or other actual or threatened solicitation of proxies or consents by or on behalf of any individual, corporation, partnership or other entity or group) cease to constitute a majority of the Board of Directors. Notwithstanding the foregoing or any provision of the RSRP to the contrary, the foregoing definition of change-in-control shall be interpreted, administered and construed in manner necessary to ensure that the occurrence of any such event shall result in a change-in-control only if such event qualifies as a change in the ownership or effective control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation, as applicable, within the meaning of Treas. Reg. § 1.409A-3(i)(5).

The following definition is provided in the 2003 Long Term Compensation Plan of the terms used in this description:

“Change-in-Control” means the occurrence of one or more of the following events: (i) any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all, or substantially all, of the assets of AES to any person or group (as that term is used in Section 13(d) (3) of the Exchange Act) of persons, (ii) a person or group (as so defined) of persons (other than AES Management on the date of the adoption of the 2003 Long Term Compensation Plan or their affiliates) shall have become the beneficial owner of more than 35% of the outstanding voting stock of AES, or (iii) during any one-year period, individuals who at the beginning of such period constitute the Board of AES (together with any new Director whose election or nomination was approved by a majority of the Directors then in office who were either Directors at the beginning of such period or who were previously so approved, but excluding under all circumstances any such new Director whose initial assumption of office occurs as a result of an actual or threatened election contest or other actual or threatened solicitation of proxies or consents by or on behalf of any individual, corporation, partnership or other entity or group) cease to constitute a majority of the Board. Notwithstanding the foregoing or any provision of the 2003 Long Term Compensation Plan to the contrary, if an award is subject to Section 409A (and not excepted therefrom) and a change-in-control is a distribution event for purposes of an award, the foregoing definition of change-in-control shall be interpreted, administered and construed in manner necessary to ensure that the occurrence of any such event shall result in a change-in-control only if such event qualifies as a change in the ownership or effective control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation, as applicable, within the meaning of Treas. Reg. § 1.409A-3(i)(5).

Director Compensation

None of our current directors receives any compensation for his or her services on the Board. The compensation for our NEOs who also serve as directors is fully reflected in the Summary Compensation Table (2023, 2022 and 2021) and other tables set forth in this Amendment. No director who served on our Board for any part of 2023 that is or was also an employee of AES Indiana, AES, or any of its affiliates, received any additional payment for their services on the Board. Information regarding the compensation received by current and former directors in their capacities as employees of our affiliates is set forth in “Item 13. Certain Relationships and Related Transactions, and Director Independence” of this Amendment. We did not have any non-employee directors who received compensation for their services on the Board in 2023.

37

Compensation Committee Interlocks and Insider Participation

The Board of IPALCO does not have a compensation committee. Please see the CD&A in this Amendment for a discussion of the process undertaken in setting executive compensation, including the persons who, during the last completed fiscal year, participated in the NEO compensation process. The Executive Compensation Review Team (consisting of the AES CEO and the AES CHRO) is responsible for reviewing and administering compensation for our NEOs. Accordingly, none of our executive officers who are also members of our Board, participate in the deliberations and/or approvals regarding their own compensation.

For information regarding the board memberships and, officer and employee positions held by our executive officers and directors with AES and other companies affiliated with IPALCO, see the biographies of our executive officers and directors included under “Item 10. Directors, Executive Officers and Corporate Governance” and the disclosures relating to these individuals included under “Item 13. Certain Relationships, Related Transactions and Director Independence,” each set forth in this Amendment and incorporated by reference herein as to this information.

CEO Pay Ratio

As required by SEC rules, we are disclosing the median of the annual total compensation of all employees of IPALCO (excluding the CEO), the annual total compensation of the CEO, and the ratio of the median of the annual total compensation of all employees to the annual total compensation of the chief executive officer.

We may identify our median employee for purposes of providing pay ratio disclosure once every three years and calculate and disclose total compensation for that employee each year, provided that, during the last completed fiscal year, there has been no change in the employee population or employee compensation arrangements that we reasonably believe would result in a significant change to the prior year’s CEO pay ratio disclosure. We reviewed the changes in our employee population and employee compensatory arrangements and determined there has been no change that would significantly impact the 2021 CEO pay ratio disclosure and ultimately require us to identify a new median employee for 2023. As a result, we used the same median employee for the 2023 CEO pay ratio as we did for the 2021 CEO pay ratio disclosure.

For the pay ratio analysis of our employee population conducted in 2021, we chose December 1st as the determination date to identify our median employee, which date was within the last three months of our most recently completed fiscal year. As of December 1, 2021, the employee population consisted of approximately 1,170 individuals. The median employee was selected using data for the following elements of compensation: salary, equity grants, and non-equity incentive compensation, over a trailing 12-month period.

For purposes of reporting annual total compensation and the ratio of annual total compensation of the CEO to the median employee, both the CEO and median employee’s annual total compensation are calculated consistent with the disclosure requirements of executive compensation under Item 402(c)(2)(x) of Regulation S-K. In 2023, both Ms. Lund and Mr. Zagzebski served as CEO of IPALCO. We used Mr. Zagzebski’s annualized compensation, which is consistent with the 2023 values reflected in the Summary Compensation Table, to calculate the CEO pay ratio for IPALCO.

For fiscal 2023, the median employee’s annual total compensation was $189,134, and the total annual compensation of our President and CEO (Mr. Zagzebski) was $1,938,110. Based on this information, the ratio of the total annual compensation of our CEO to the total annual compensation of our median employee for fiscal 2023 is 10.25:1.

38

The Company has not made any of the adjustments permissible by the SEC, nor have any material assumptions or estimates been made to identify the median employee or to determine total annual compensation.

ITEM 12.    SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS                            

The following two tables set forth information regarding the beneficial ownership of IPALCO’s Common Stock as of March 15, 2024 based on 108,907,318 shares outstanding as of such date, and AES’ Common Stock as of March 15, 2024 based on 710,808,795 shares outstanding as of such date by (a) each current Director of IPALCO and each NEO set forth in the Summary Compensation Table in this Amendment, (b) all Directors and Executive Officers of IPALCO as a group and (c) all persons who are known by IPALCO to be the beneficial owners of more than five percent (5%) of the Common Stock of IPALCO.

Under these rules, more than one person may be deemed the beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. Except as otherwise indicated in the footnotes below, each of the beneficial owners has, to the best of our knowledge, sole voting and investment power with respect to the indicated shares of IPALCO and AES Common Stock.

Certain Relationships and Related Transactions, and Director Independence" of this Amendment.

(2)    The shares of AES Common Stock beneficially owned are reported on the basis of SEC regulations governing the determination of beneficial ownership of securities. Under the SEC rules, shares of AES Common Stock, which are subject to options, units or other securities that are exercisable or convertible into shares of AES Common Stock within 60 days of March 15, 2024, are deemed to be outstanding and beneficially owned by the persons holding such options, units or other securities. Such underlying shares of Common Stock are deemed to be outstanding for the purpose of computing such person’s ownership percentage, but not deemed to be outstanding for the purpose of computing the percentage ownership of any other person.

(3)    Includes (a) the following shares issuable upon exercise of options outstanding as of March 15, 2024 that are able to be exercised within 60 days of March 15, 2024: Mr. Buchanan – 0 shares; Mr. Coughlin – 0 shares; Mr. Da Santos – 66,250 shares; Ms. Davis-Handy – 0 shares; Mr. Falú – 0 shares; Mr. Freedman - 0 shares; Mr. Garavaglia – 0 shares; Ms. Harcourt – 0 shares; Mr. Hylander – 0 shares; Mr. Lesage - 0 shares; Ms. Lund – 0 shares; Ms. Mendoza – 66,250 shares; Mr. Michael – 0 shares; Mr. Pasha – 0 shares; Mr. Roy Durocher – 0 shares; Mr. Zagzebski – 0 shares; all directors and executive officers as a group - 132,500 shares; (b) the following shares held in The AES Retirement Savings Plan: Mr. Buchanan - 1,106 shares; Mr. Coughlin – 0 shares; Mr. Da Santos - 30,211 shares; Ms. Davis-Handy – 0 shares; Mr. Falú – 0 shares; Mr. Freedman - 2,835 shares; Mr. Garavaglia – 0 shares; Ms. Harcourt - 0 shares; Mr. Hylander – 2,123 shares; Mr. Lesage - 0 shares; Ms. Lund - 0 shares; Ms. Mendoza – 27,276 shares; Mr. Michael - 14 shares; Mr. Pasha – 0 shares; Mr. Roy Durocher - 0 shares; Mr. Zagzebski – 0 shares; all directors and executive officers as a group – 63,565 shares. Data provided for Ms. Lund and Mr. Pasha is as of March 15, 2023, and is adjusted to reflect forfeiture of all of their unvested equity upon their resignation from AES.

Change in Control

IPALCO was acquired by AES in March 2001, and currently is majority-owned by AES U.S. Investments, with a minority interest held by CDPQ, a wholly owned subsidiary of La Caisse de dépȏt et placement du Québec. AES U.S. Investments is owned by AES U.S. Holdings, LLC (85%) and CDPQ (15%). AES U.S. Holdings, LLC is wholly owned by AES. A pledge by AES on its interests in AES U.S. Holdings, LLC would become effective under the terms of certain of AES’ credit arrangements if AES in

40

the future did not meet certain investment grade credit ratings. Any exercise of remedies under such pledge could result at a subsequent date in a change in control of IPALCO.

Equity Securities under Compensation Plans

As described in this Amendment, there are no equity compensation plans under which equity securities of IPALCO are authorized for issuance. All equity compensation plans provide for the issuance of AES Common Stock. For information regarding AES’ LTC Plan, see the “Securities Authorized for Issuance under Equity Compensation Plans (As of December 31, 2023)” table in the AES 10-K.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Insurance, Employee Benefit Plans and Tax Arrangements with AES

AES Indiana participates in a property insurance program in which AES Indiana buys insurance from AES Global Insurance Company, a wholly owned subsidiary of AES. AES Indiana is not self-insured on property insurance but does take a $5 million per occurrence deductible. Except for AES Indiana’s large substations, AES Indiana does not carry insurance on transmission and distribution assets, which are considered to be outside the scope of property insurance. AES and other AES subsidiaries, including IPALCO, also participate in the AES global insurance program. AES Indiana pays premiums for a policy that is written and administered by a third-party insurance company. The premiums paid to this third-party administrator by the participants are paid to AES Global Insurance Company and all claims are paid from a trust fund funded by and owned by AES Global Insurance Company but controlled by a third-party administrator. AES Indiana also has third-party insurance in which the premiums are paid directly to the third-party insurers. The cost to AES Indiana of coverage under the property insurance program with AES Global Insurance Company was approximately $11.7 million, $9.5 million and $7.0 million in 2023, 2022 and 2021, respectively, and is recorded in “Operating expenses - Operation and maintenance” on the Consolidated Statements of Operations accompanying the 2023 10-K. As of December 31, 2023, and 2022, we had prepaid approximately $7.5 million and $3.4 million, respectively, for coverage under these plans, which is recorded in “Prepayments and other current assets” on the Consolidated Balance Sheets accompanying the 2023 10-K.

AES Indiana participates in an agreement with Health and Welfare Benefit Plans LLC, an affiliate of AES, to participate in a group benefits program, including but not limited to, health, dental, vision and life benefits. Health and Welfare Benefit Plans LLC administers the financial aspects of the group insurance program, receives all premium payments from the participating affiliates, and makes all vendor payments. The cost of coverage under this program was approximately $19.0 million, $25.3 million and $23.7 million in 2023, 2022 and 2021, respectively, and is recorded in “Operating expenses - Operation and maintenance” on the Consolidated Statements of Operations accompanying the 2023 10-K. We had no prepaids for coverage under this plan as of December 31, 2023, and 2022, respectively.

AES files federal and state income tax returns, which consolidate IPALCO and its subsidiaries. Under a tax sharing agreement with AES, IPALCO is responsible for the income taxes associated with its own taxable income and records the provision for income taxes using a separate return method. IPALCO had a receivable balance under this agreement of $36.5 million and $18.0 million as of December 31, 2023, and 2022, respectively, which is recorded in “Taxes Receivable” on the Consolidated Balance Sheets accompanying the 2023 10-K. See Note 7, "Income Taxes" to the audited consolidated financial statements of IPALCO for more information.

Long Term Compensation Plan

During 2023, 2022 and 2021, many of AES Indiana’s non-union employees received benefits under the AES LTC Plan. This type of plan is a common employee retention tool used in our industry. Benefits under this plan include awards granted in the form of PUs and PCUs payable in cash and AES RSUs and PSUs payable in AES Common Stock. RSUs vest ratably over a three-year period generally subject to

41

continued employment, and PSUs vest, if earned, at the end of a three-year period based on performance and continued employment. The PUs and PCUs are payable in cash and vest at the end of the three-year performance period and are subject to certain AES performance criteria. Total deferred compensation expense recorded during 2023, 2022 and 2021 was $0.3 million, $0.2 million and $0.2 million, respectively, and was included in “Operating expenses - Operation and maintenance” on IPALCO’s Consolidated Statements of Operations accompanying the 2023 10-K. The value of these benefits is being recognized over the 36-month vesting period and a portion is recorded as miscellaneous deferred credits with the remainder recorded as “Paid in capital” on IPALCO’s Consolidated Balance Sheets accompanying the 2023 10-K in accordance with ASC 718 “Compensation - Stock Compensation.”

See also Note 8, “Benefit Plans” to the audited consolidated financial statements of AES Indiana for a description of benefits awarded to AES Indiana employees by AES under the RSP.

Service Company

Effective January 1, 2014, the Service Company began providing certain services including operations, accounting, legal, human resources, information technology and other corporate services on behalf of companies that are part of the US Operations. The Service Company allocates the costs for these services based on cost drivers designed to result in fair and equitable allocations. This includes ensuring that the regulated utilities served, including AES Indiana, are not subsidizing costs incurred for the benefit of non-regulated businesses. Total costs incurred by the Service Company on behalf of IPALCO were $73.8 million, $60.3 million and $58.4 million during 2023, 2022 and 2021, respectively. Total costs incurred by IPALCO on behalf of the Service Company during 2023, 2022 and 2021 were $11.9 million, $10.0 million and $10.4 million, respectively, which are included as a reduction in charges from the Service Company. These costs were included in “Operating expenses - Operation and maintenance” on IPALCO’s Consolidated Statements of Operations accompanying the 2023 10-K. IPALCO had a payable balance with the Service Company of $25.6 million and $2.1 million as of December 31, 2023, and 2022, respectively, which is recorded in “Accounts payable” on the Consolidated Balance Sheets accompanying the 2023 10-K.

Shareholders’ Agreement

AES U.S. Investments, IPALCO and CDPQ are parties to a Shareholders’ Agreement dated February 11, 2015. The Shareholders’ Agreement established the general framework governing the relationship between CDPQ and AES U.S. Investments and their respective successors and transferees, as shareholders of IPALCO. The Shareholders’ Agreement provides AES U.S. Investments the right to nominate nine directors of the IPALCO Board and CDPQ the right to nominate two directors of the IPALCO Board. If the amount of outstanding IPALCO shares beneficially owned by CDPQ is equal to or less than the lesser of (A) 8.825% and (B) one-half of the Maximum Subscription Percentage (as defined in the Shareholders’ Agreement) but remains greater than the lesser of (x) one-third of 17.65% and (y) one-third of the Maximum Subscription Percentage, then CDPQ shall have the right to nominate one director. Additionally, if at any time the amount of outstanding IPALCO shares beneficially owned by CDPQ decreases to less than or equal to the lesser of (A) one-third of 17.65% and (B) one-third of the Maximum Subscription Percentage, then CDPQ shall cease to have any rights to nominate any directors. The Shareholders’ Agreement contains restrictions on IPALCO making certain major decisions without the prior affirmative vote of a majority of the IPALCO Board. In addition, for so long as CDPQ beneficially owns at least 5% of the total number of IPALCO shares outstanding, CDPQ will have review and consultation rights with respect to certain actions of IPALCO. Certain transfer restrictions and other transfer rights also apply to CDPQ and AES U.S. Investments under the Shareholders’ Agreement, including certain rights of first offer, drag along rights, tag along rights, put rights and rights of first refusal.

Other

42

In the second quarter of 2023, AES Indiana engaged a vendor that is a related party through a competitive RFP process as part of its replacement capacity resource construction projects. AES Indiana had payments of $223.3 million to this vendor during the year ended December 31, 2023, which are included in "Other non-current assets" on the accompanying Consolidated Balance Sheets. Transactions with various other related parties were $7.4 million, $5.7 million and $4.3 million during 2023, 2022 and 2021, respectively. These expenses were primarily recorded in “Operating expenses - Operation and maintenance” on the accompanying Consolidated Statements of Operations.

Related Person Policies and Procedures

IPALCO is owned by two shareholders, one of which is wholly-owned by AES. As such, IPALCO does not maintain the type of separate related person transaction policy that is customarily maintained by more widely-held public companies. The US and Utilities has a designated compliance officer who ensures that the core values of AES and its subsidiaries are communicated to, and followed by, employees throughout the organization as set forth in the Code of Conduct and other policies adopted by IPALCO and its affiliated companies. The Code of Conduct expressly requires that employees avoid conflicts of interests and engage in fair dealing, among other requirements, to ensure that transactions entered into by IPALCO, and other affiliated companies are in the best interests of the organization.

AES Indiana and IPALCO also utilize a due diligence questionnaire with certain business partners, vendors and suppliers as part of the corporate compliance program to ensure that the highest ethical and legal standards are upheld in all business transactions. The corporate compliance program includes a “know your business partner” program, which requires us to conduct due diligence on prospective business partners prior to entering into certain business agreements with an estimated value in excess of $250,000, for U.S. based transactions, or that are otherwise identified as high risk. Our compliance program requires that the due diligence questionnaires for all such business partners be updated prior to execution of any new agreement with AES Indiana or IPALCO if the questionnaire on file is more than two years old.

A due diligence questionnaire is also completed annually by directors and executive officers in order to determine if a related person transaction or other conflict of interest or potential conflict of interest may exist that should be brought to the attention of the designated compliance officer of the US and Utilities and/or the Office of the General Counsel for further investigation and analysis. The designated compliance officer of the US and Utilities and/or the Office of the General Counsel may take action to approve or recommend the approval of a related person transaction, or determine to take other appropriate actions, based on the facts and circumstances.

Employees of IPALCO and CDPQ Affiliated Companies

None of our Board members are directly employed by IPALCO. All of our Board members are employees of our two shareholders and/or their affiliated companies, and only receive compensation in their capacities as employees of these affiliated entities. The compensation paid to IPALCO directors that are also NEOs for services performed as employees of our affiliates for 2023 is set forth in “Item 11. Executive Compensation” of this Amendment. None of our Board members are compensated for their service on our Board.

The compensation received by each of our executive officers and directors who are employees of companies affiliated with AES was in excess of $120,000 in 2023 for services performed on behalf of AES or the US and Utilities, including for services provided to IPALCO and AES Indiana. The components of the compensation paid to all of our executive officers in 2023 was consistent with the compensation elements for our NEOs as disclosed in “Item 11. Executive Compensation” of this Amendment.

For information regarding the board memberships and officer and employee positions held by our executive officers and directors with AES and other companies affiliated with IPALCO, see the biographies of our executive officers and directors included under “Item 10. Directors, Executive Officers
