  65. Executive Compensation Changes

    Executive Compensation Changes The Company is committed to actively engaging with shareholders and making changes to the compensation program to ensure that it represents our strong commitment to the Company's and APS's pay-for-performance philosophy. Each year the Human Resources Committee (for purposes of the CD&A, the "Committee") reviews the various components of the executive compensation program to determine if changes should be made. The Committee believes the program is functioning well, and as a result, didn't make major changes to the program in 2025. However, over the past several years, the Committee has undertaken the following: •ensured performance-based plan goals are set with appropriate levels of rigor; •increased percentage of at-risk compensation; and •sought alignment of our equity grants with best practices, including removed full vesting upon reaching retirement eligibility and discontinued provisions which provided for certain vesting rights for individuals who met the definition of a late career recipient. Looking ahead, for our 2026 equity grants, the Committee made the following changes to our performance share metrics to better align with our strategic priorities and mission to deliver safe, reliable and affordable energy and our commitment to delivering shareholder value: •replaced the prior MW Installed metric with a new metric blending reliability and affordability; and •modified the weighting of the three metrics to align Company and shareholder priorities.

  68. 2025 Compensation Plan

    (1)Messrs. Geisler and Guldner participated in the APS 2025 Annual Incentive Award Plan (the “APS Incentive Plan”). However, under the APS Incentive Plan, Messrs. Geisler's and Guldner’s incentive opportunity tied to earnings was based on PNW earnings and not APS earnings and Mr. Guldner was not eligible for an incentive opportunity under the APS Incentive Plan for the portion of time in his role as Special Advisor to the CEO in 2025. For additional details regarding Messrs. Geisler's and Guldner’s incentive award for 2025, please refer to pages 62-67. (2)Based on the following business units, as applicable: Corporate Resources (Information Technology), Corporate Resources (Resource Management), Corporate Resources (excluding Resource Management and Information Technology), Customer Experience and Communications, Generation (non-nuclear including new generation), Transmission and Distribution, and PVGS. For additional details regarding our goal-setting process and the specific business unit goals for 2025, please refer to pages 76-77 and 79-80. (3)In 2026, we replaced this MW Installed metric with a new metric blending reliability and affordability. The MW Installed links pay to the successful construction and delivery buildout of resources that were previously contracted for as a result of prior ASRFPs, which we believe will deliver reliable and affordable energy. For additional details see page 70 of this Proxy Statement. (4)For our 2025 annual long-term equity awards, Messrs. Geisler, Heflin, Tetlow and Smith were granted 70% performance shares and 30% RSUs and Mr. Cooper and Ms. Baum were granted 60% performance shares and 40% RSUs. Mr. Guldner did not receive an annual long-term equity award for 2025. For additional details regarding our goal-setting process and the specific long-term goals for 2025 performance share awards, please refer to pages 69-70.

  69. 2025 Annual Incentive Award

    2025 Annual Incentive Award The Board oversees the Company’s business strategy. The Company maintains a rigorous performance goal-setting process wherein targets are set during our annual business planning process based on strategies and goals that address our long-term issues. •The Committee annually reviews the earnings goal and business unit metrics to ensure alignment with the financial plan and business strategy, with target performance set at levels that are intended to be challenging without incentivizing inappropriate risk taking. •The Company’s goal setting process is guided by our long-term objectives and strategic priorities, using a blend of business considerations, industry benchmark data, and opportunities to improve performance to ensure the appropriate level of rigor. The 2025 annual incentive earnings and business unit components were set with these practices and philosophy as further described on pages 62-67 of this Proxy Statement.

  70. 2025 Long-Term Incentive Awards

    2025 Long-Term Incentive Awards Our long-term equity incentive compensation is intended to align the interests of executives and our shareholders and increase long-term shareholder value, while also offering an award opportunity that helps attract and retain qualified, experienced executives. The 2025 long-term annual incentive grants awarded to our NEOs were granted consistent with our executive compensation practices and philosophy as described on page 60 of this Proxy Statement.

  71. Role of Compensation Consultants

    Role of Compensation Consultants Under its charter, the Committee has the sole authority to retain and terminate a consulting firm to assist the Committee in carrying out its responsibilities. The Committee engaged the Consultant to assist in its evaluation of 2025 compensation for our executive officers. In particular, the Committee instructed the Consultant to prepare a competitive analysis of the compensation of the executive officers of the Company and of APS, and to make recommendations for changes to the existing compensation program, if warranted. The Consultant does not provide any other services to the Company nor its affiliates. The Committee has assessed the independence of the Consultant and has concluded that the Consultant is independent as determined under the NYSE rules.

  74. Application of the Committee’s Judgment

    Application of the Committee’s Judgment The analysis in the Consultant’s report and its recommendations regarding the competitiveness and structure of compensation are factors that the Committee takes into account in its evaluation of compensation for the NEOs. The Committee considers the competitive market data presented by the Consultant as an important reference point to assure the Committee of the reasonableness of compensation levels and programs provided to executive management; however, actual compensation levels also take into account the individual executives and their responsibilities, skills, expertise, value added, as well as the competitive marketplace for executive talent. Company, business unit, and individual officer performance, as well as compensation competitiveness, are the primary factors in determining the level of total direct compensation for the NEOs. While the Committee considers internal pay equity in making compensation decisions, we do not have a policy requiring any set levels of internal pay differentiation. Finally, the Committee evaluates other factors that it considers relevant, such as the financial condition of the Company and APS. The Company does not have a pre-established policy or target for allocation between cash and non-cash compensation or between short-term and long-term incentive compensation, although the Committee does have a pre-established allocation between performance-based and time-based equity awards.

  75. Determining the Peer Group

    Determining the Peer Group The Peer Group (defined below) used as one input in our pay comparison process is reviewed annually to ensure it remains appropriate. In constructing the Peer Group, the Committee takes into consideration the scope and complexity of the Company’s management responsibility and liability exposures, including the following factors: •Pinnacle West’s operating subsidiary, APS, operates PVGS, one of the largest nuclear power plant in the U.S., which has over a $1.2 billion annual budget, employs approximately one-third of APS employees, and is subject to comprehensive and complex nuclear and environmental regulation; •the management scope of the PVGS operations requires the Company to seek talent from larger utilities, including those with significant nuclear operations and similar regulatory and business challenges; and •APS has full operational control and legal responsibility for PVGS and Four Corners. This is an important factor because APS does not have 100% ownership of these stations and, therefore, our full operational responsibility is not accounted for in standard measures of Pinnacle West’s or APS’s size. Given these factors, we make certain adjustments to our size measure to account for our operational responsibilities to allow for more appropriate comparability of Pinnacle West to potential peer companies. In particular, we adjust our revenues to reflect our control and responsibility for PVGS and Four Corners. The amount used for APS revenues is adjusted to take into account the revenues that are attributable to co-owned assets over which APS maintains full operational control and legal compliance responsibility. This adjustment resulted in an amount of $6.7 billion in revenues compared to its reported twelve months ended June 30, 2024 revenues of $4.9 billion. Within the range of potential peers based on adjusted revenues, the Peer Group is then determined based on additional factors including: •scope of management complexity; •nuclear operations; •top industry talent (related to management complexity); •regulated vs. non-regulated operations; and •complexities of a challenging regulatory environment. As a result of its most recent review, the Committee approved the use of the same Peer Group that was used in setting 2024 executive compensation. The Peer Group is broadly similar to the Company in scope and complexity of operations (taking into account nuclear operations, regulatory profile, and other quantitative and qualitative considerations) and positions the Company between the 25th percentile and median with respect to revenues (adjusted as explained above).

    As outlined previously, peer proxy data is only one-third of the compensation information that is referenced for our NEOs (except for Mr. Heflin, where peer proxy statement data is weighted at 50%). For setting 2025 compensation, the Peer Group consisted of the following predominantly rate-regulated utilities (the “Peer Group”):

  80. Base Salary

    Base Salary Base salaries are set at competitive levels to attract and retain qualified, experienced executives. Salary levels are based on experience, performance and responsibilities, and benchmarked to the Peer Group and market survey data to align with competitive levels. The Committee reviews competitive salary information and individual salaries for executive officers on an annual basis. In considering individual salaries, the Committee reviews the scope of job responsibilities, individual contributions, business performance, retention concerns, and current compensation compared to market practices. The Committee also considers that base salary is used as the basis for calculating annual incentive awards. In December 2024, the Committee set the base salaries for fiscal year 2025 at the following:

  81. Annual Cash Incentives

    Annual Cash Incentives Our annual cash incentives are strongly performance-based and designed to both reward achievement of pre-determined annual performance objectives that are critical to our business operations and to attract and retain qualified, experienced executives. Performance for NEOs is measured based on relevant and objective earnings and business unit metrics. •CEO. Messrs. Geisler and Guldner participated in the APS Incentive Plan, but the award opportunities are based 50% on the achievement of 2025 Pinnacle West earnings levels and 50% on the achievement of enterprise shared metrics that are aligned with achieving our strategic goals and APS business unit performance goals in the functional areas of customer experience and communications, transmission and distribution, generation (non-nuclear including new generation), corporate resources, and PVGS. In accordance with the 2025 APS Incentive Plan terms, Mr. Guldner was not eligible for an annual cash incentive award for the portion of time he was Special Advisor to the CEO in 2025. •Other NEOs. Messrs. Cooper, Tetlow and Smith and Ms. Baum participated in the APS Incentive Plan and Mr. Heflin participated in the APS 2025 Annual Incentive Award Plan for Palo Verde Employees (the “Palo Verde Incentive Plan”). In accordance with the 2025 APS Incentive Plan terms, Mr. Smith was not eligible for an annual cash incentive award for the portion of time he was Special Advisor to the CEO in 2025. The APS Incentive Plan and the Palo Verde Incentive Plan are collectively referred to as the “2025 Incentive Plans.” In December 2024, the Committee approved the CEO portion of the APS Annual Incentive Plan and the Board, on the recommendation of the Committee, approved the 2025 Incentive Plans for all other officers.

    2025 Incentive Plan Target Setting Process

  94. 2025 PNW and APS Incentive Plan Results — Earnings

    2025 PNW and APS Incentive Plan Results — Earnings For incentive plan purposes, earnings for Pinnacle West were 182% of target and earnings for APS were 173% of target, at $594.7 million and $667.3 million, respectively, as shown below. The 2025 earnings results for the 2025 Incentive Plans were driven primarily by: •increased customer growth resulting in higher than expected weather-normalized sales growth; and •higher transmission service revenues. The earnings portion of the annual cash incentive for Mr. Geisler as CEO and former CEO Mr. Guldner, was determined based on Pinnacle West earnings weighted at 50% of the award. For all NEOs other than the CEO, the earnings portion of the annual cash incentive was determined based on APS earnings and weighted at 50% of the award. The APS Incentive Plan provides that if the threshold earnings number is not met, no incentive payment will be awarded, regardless of business unit performance. The Palo Verde Incentive Plan provides that if the threshold earnings number is not met, the APS earnings portion of the incentive payment will not be awarded. In addition, under the Palo Verde Incentive Plan, PVGS’s overall business unit performance was required to achieve at least 100% of the target level for 2025 before Mr. Heflin could receive any payout under the APS earnings portion.

  98. 2025 PNW and APS Incentive Plan Results — Earnings

    Under the terms of the 2025 Incentive Plans, the Committee may adjust plan targets or incentive results and may make other changes to the plan deemed necessary or appropriate due to unanticipated events that arise during the performance period or unusual or non-recurring adjustments on actual earnings that arise during the performance period, including without limitation, ACC rate-related impacts on earnings. For 2025, the Committee adjusted Pinnacle West earnings to remove the impact of investment gains at our subsidiary El Dorado. The net effect of this adjustment was a decrease to PNW earnings from $616.5 million to $594.7 million and thereby lowering the payout percentage. The investment gain did not impact APS earnings, and the Committee made no adjustments to APS 2025 earnings numbers for purposes of the 2025 Incentive Plans.

    2025 PNW and APS Incentive Plan Results — Business Unit Metrics The 2025 average of all business unit metrics performance for 2025 was 127% of target compared to 145% of target in 2024.

  102. 2025 PNW and APS Incentive Plan Results — Business Unit Metrics

    (1)Results reflect that the PNW O&M shared enterprise metric target was not automatically adjusted upon issuance of revised O&M Guidance as would have been permitted by the terms of the APS Incentive Plans (see below for further details). As indicated above, NEOs are evaluated based on shared enterprise metrics and/or business area specific metrics that correlate to their responsibilities. The business unit component for each NEO was weighted at 50%, with multiple business area results averaged for applicable NEOs. The 2025 Incentive Plans allow the Committee to make adjustments for individual performance, and the Committee may exercise discretion under the 2025 Incentive Plans due to unanticipated events that might arise during the performance period. In 2025, management authorized increased enterprise O&M spend due to benefits of strong sales. Given the continued focus on customer affordability, the Committee decided to not automatically adjust the PNW O&M shared enterprise metric even though the APS Incentive Plan permitted an adjustment based on the revised O&M guidance range, which resulted in no payout for this metric that would have otherwise earned one. The following table summarizes the shared enterprise metrics and/or business area specific metrics used for each business unit, in addition to individual weightings, targets, and 2025 results. Under the components of the 2025 Incentive Plans, the range of potential achievement for each business unit metric was zero to 200% of the target level. Within that range, a target level of achievement provided for a 100% payout, a threshold level provided for a 50% of target payout, and a maximum level provided for a 200% of target payout.The percentage of target performance achieved reflects the comparison of our actual achievement of a particular measure for 2025 to the target established for that measure.

  110. Long-Term Incentives

    Long-Term Incentives Our long-term equity incentive compensation is intended to align the interests of executives and our shareholders and increase long-term shareholder value while also offering an award opportunity that helps attract and retain qualified, experienced executives. The Company currently uses two types of equity awards: performance shares and RSUs. For our CEO and Executive Vice Presidents in 2025, our annual long-term equity awards were granted 70% to performance-based measures and 30% to time-based vesting, and for all other NEO officers, 60% to performance-based measures and 40% to time-based vesting.

  113. 2025 Long-Term Equity Incentive Component Summary

    (1)For our 2025 annual long-term equity awards, Messrs. Geisler, Heflin, Tetlow and Smith, were granted 70% performance shares and 30% RSUs; Mr. Cooper and Ms. Baum were granted 60% performance shares and 40% RSUs. In April 2025, Mr. Geisler received an additional promotional long-term equity award granted as 70% performance shares and 30% RSUs. (2)In 2026, we replaced this MW Installed metric with a new metric blending reliability and affordability. The MW Installed links pay to the successful construction and delivery buildout of resources that were previously contracted for as a result of prior ASRFPs, which we believe will deliver reliable and affordable energy. For additional details see page 70 of this Proxy Statement. To determine the amount of performance share and RSU awards for the annual grants made in February 2025, the Committee first established a target compensation value for each officer that it wanted to deliver through long-term equity award opportunities. The Committee considered various factors, including the retention value of the total compensation package, the long-term equity component in light of the competitive environment, and individual performance. The Committee also considered target value, taking into consideration the Company’s achievement of earnings targets, and overall performance. Once the target value was established, the Committee determined the number of shares subject to the awards by reference to the then-current market value of the Company’s common stock, and then allocated the 2025 awards 70% to performance shares and 30% to RSUs for the CEO and Executive Vice Presidents, 60% to performance shares and 40% to RSUs for all Senior Vice Presidents, and 50% to performance shares and 50% to RSUs for all other officers. The 2025 awards to the NEOs were as follows:

  117. Performance Shares

    Performance Shares

  118. 2025 Performance Shares

    2025 Performance Shares In 2025, we granted performance shares to our NEOs, with the exception of Mr. Guldner, for a three-year performance period (the “2025 Performance Shares”) with three distinct elements — Relative TSR, EPS performance, and MWs Installed.

  119. 2025 Performance Shares

    | Metrics | Weighting | Rationale and Performance Link | | Relative TSR Measures the Company’s TSR performance against EEI Index | 40% | Links pay to shareholder value creation relative to others in the industry | | EPS Performance Measures the Company’s actual EPS to our EPS target | 40% | Links pay to financial targets that generate shareholder value | | MW Installed(1) Measures the Company’s clean MWs installed to our clean MWs installed target | 20% | Links pay to successful construction and delivery buildout of resources from prior ASRFPs. |

  120. 2025 Performance Shares

    (1)In 2026, we replaced this MW Installed metric with a new metric blending reliability and affordability. The MW Installed links pay to the successful construction and delivery buildout of resources that were previously contracted for as a result of prior ASRFPs, which we believe will deliver reliable and affordable energy. See below for additional details. The Committee grants each award recipient a specified number of performance shares, which is allocated based on a weighting and considered the “Base Grant” for each performance element. Under each of the performance elements, the maximum award opportunity is 200% of the Base Grant, which reflects the performance of the three elements. We anticipate that the common stock payout, if any, for each element described below will be made in March 2028.

  121. TSR

    | Relative TSR Performance Scale | Performance Share Payout | Total Maximum Award Opportunity | | 90th Percentile or Greater | 200% of the Base Grant | 200% of Base Grant | | 55th Percentile(1) | 100% of the Base Grant | | | 25th Percentile | 25% of the Base Grant | | | Less than 25th Percentile | None | |

  122. EPS Performance

    | Average EPS Performance Scale | Performance Share Payout | Total Maximum Award Opportunity | | 110.0% | 200% of the Base Grant | 200% of Base Grant | | 100.0% | 100% of the Base Grant | | | 95.0% | 25% of the Base Grant | | | Less than 95.0% | None | |

  123. MW Installed(1)

    | Actual MW Installed Performance Scale | Performance Share Payout | Total Maximum Award Opportunity | | 105.0% | 200% of the Base Grant | 200% of Base Grant | | 90.0% | 100% of the Base Grant | | | 75.0% | 25% of the Base Grant | | | Less than 75.0% | None | |

  124. Looking Ahead: 2026 Performance Shares

    Looking Ahead: 2026 Performance Shares In 2026, we made changes to our performance share metrics and weightings to better align with our strategic priorities and mission to deliver safe, reliable and affordable energy and our commitment to delivering shareholder value. The Committee replaced the prior MW Installed metric with a new metric blending reliability and affordability. The weighting of the three metrics (Relative TSR, EPS Performance and Reliable and Affordable) was also modified to align Company and shareholder priorities. These changes went into effect beginning with the February 2026 grants to our NEOs for the three-year performance period beginning January 1, 2026.

  125. Looking Ahead: 2026 Performance Shares

    | Metrics | Weighting | Rationale and Performance Link | | Relative TSR Measures the Company’s TSR performance against EEI Index | 34% | Links pay to shareholder value creation relative to others in the industry | | EPS Performance Measures the Company’s actual EPS to our EPS target | 33% | Links pay to financial targets that generate shareholder value | | Reliable and Affordable Measures the Company’s Residential Cents per kWh and SAIFI, All Interruptions against EEI utilities | 33% | Links pay to mission of serving our customers with safe, reliable and affordable energy |

    Payouts of Plan Awards

  127. 2022 Plan Awards

    | | Relative TSR (1) | EPS Performance(2) | MW Installed(3) | Total PS Grant Payout | | 2022 Grant - CEO & EVP | 72.8% | 73.7% | 40.0% | 186.5% | | 2022 Grant - All Other NEOs | 73.7% | 73.7% | 40.0% | 187.4% |

  128. 2022 Plan Awards

    (1)The payout percentage reflects 40% weight of the actual TSR percentile performance of 83.7%. (2)The payout percentage reflects 40% weight of the average EPS performance of 108.4%. (3)The payout percentage reflects 20% weight of the actual MW Installed metric performance of 125.0%. In 2026, we replaced this MW Installed metric with a new metric blending reliability and affordability. The MW Installed links pay to the successful construction and delivery buildout of resources that were previously contracted for as a result of prior ASRFPs, which we believe will deliver reliable and affordable energy. See above for additional details.

  129. 2023 Plan Award

    2023 Plan Award In 2023, the Committee granted performance shares to the NEOs based on relative TSR, EPS Performance, and MW Installed metrics. For the three-year period ending December 31, 2025, the total payout of the 2023 performance share grant was 159% for our CEO and Executive Vice Presidents and 161.5% for all others NEOs. The value of shares paid to each NEO will not be determined until the end of the first quarter of 2026. See the Outstanding Equity Awards at Fiscal Year-End table for more information on these awards.

  130. RSUs

    RSUs In 2025, we granted RSUs to our NEOs with the exception of Mr. Guldner. RSUs vest in equal 25% installments over four years if the award recipient remains employed by the Company, or one of its subsidiaries, unless the recipient meets any of the exceptions described under “Potential Payments upon Termination or Change of Control”. Each RSU represents the fair market value of one share of our common stock on the applicable vesting date, and the value rises and falls with the Company’s stock price. Dividend equivalents, payable in cash, are credited on each RSU to the same extent that dividends are declared and paid on our common stock and treated as reinvested, but are paid only if the associated RSU vests. The 2025 RSUs are included in the Summary Compensation Table in the column under “Stock Awards” and in the Grants of Plan-Based Awards table. RSUs granted in previous years that vested in 2025 are identified in the Option Exercises and Stock Vested table.

  131. Change of Control Agreements

    Change of Control Agreements The Company maintains Key Executive Employment and Severance Agreements (the “Change of Control Agreements”) for our officers, including the NEOs. Similar to our deferred compensation programs, Change of Control Agreements do not have a significant impact on compensation design. We discuss our Change of Control Agreements in more detail under “Potential Payments upon Termination or Change of Control". Our Change of Control Agreements are “double trigger” agreements that provide severance benefits if, during a specified period following a change of control, the Company terminates an employee without “cause” or the employee terminates employment “for good reason”, as such terms are defined under such agreements. We believe that the possibility of strategic transactions or unsolicited offers creates job uncertainty for executives, and that the Change of Control Agreements provide effective incentives for executives to stay with the Company in light of these uncertainties. In addition, we believe that if the agreements are appropriately structured, they do not deter takeovers or disadvantage shareholders. Each agreement is terminable by the Company on notice given six months prior to each anniversary of the agreement. In May 2009, in connection with a review of its executive compensation practices, the Company determined that, on a going-forward basis, it would no longer provide excise tax gross-up payments in new or materially amended Change of Control Agreements with its NEOs, but provided for an exception that gave the Company the ability to include a limited excise tax gross-up provision in connection with recruiting a new executive to the Company. In 2018, the Committee removed this exception. Since 2021, the Change of Control Agreements for all NEOs (except Mr. Guldner, whose agreement was not amended nor modified) contain a “best net benefit” provision which provides that the Company’s payments to the officer can be reduced to the extent that no portion of the reduced payments shall be subject to certain excise taxes under the Internal Revenue Code of 1986 (the “Code”), but only if the officer’s net after-tax benefit is greater than his or her net after-tax benefit would have been if such reduction were not made and the officer paid the excise tax. In addition to the Change of Control Agreements described above, under the terms of our 2012 Plan and 2021 Plan, awards are accelerated upon a change of control, unless the Board chooses to override such provisions. In exercising its override authority, the Board must conclude, in good faith, that participants’ awards will remain outstanding, be assumed by any successor company, or be exchanged for new awards pursuant to a change of control, and that there will be no material impairment to either the value of the awards or the opportunity for future appreciation in respect of the awards.

    (1)In this column, the abbreviation “PS” means performance share awards and “RSU” means restricted stock unit awards. (2)As required by SEC rules, the “Estimated Future Payouts” represent the “threshold,” “target,” and “maximum” payouts the NEOs were eligible to receive under the 2025 Incentive Plans. The actual awards paid to the NEOs under the 2025 Incentive Plans are disclosed in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table. With respect to Messrs. Geisler, Guldner, Cooper, Tetlow and Smith and Ms. Baum, the minimum amount each officer would have been eligible to receive was calculated based on earnings achieving 1% and no achievement of the business unit performance metrics. The minimum amount Mr. Heflin would have been eligible to receive was calculated based on the business unit performance metrics achieving 1% and no achievement of the APS earnings goals under the Palo Verde Incentive Plan. (3)The amounts in this column reflect the aggregate grant date fair value of performance shares and RSUs computed in accordance with FASB ASC Topic 718. (4)This amount represents the 2025 Performance Shares described under “Executive Compensation Components — Long-Term Incentives — Performance Shares” in the CD&A. In accordance with FASB ASC Topic 718, the TSR performance share value reported is based on the probable outcome of the performance conditions as of the grant date using a Monte Carlo simulation model: February grants for Messrs. Geisler, Heflin, Tetlow, and Smith ($104.72); February grants for Mr. Cooper and Ms, Baum ($109.05); and Mr. Geisler's April grant ($113.87). The EPS and MW Installed performance share values are based on the closing stock price on the date of grant: February grants ($89.89); and Mr. Geisler's April grant ($95.28). (5)This amount represents the 2025 RSU awards described under “Executive Compensation Components — Long-Term Incentives — RSUs” in the CD&A. In accordance with FASB ASC Topic 718, we valued the RSUs using the number of RSUs awarded multiplied by the closing stock price on the date of the grant as follows: in February 2025 ($89.89); and in April for Mr. Geisler ($95.28). There were no forfeitures in 2025. (6)These amounts represent Mr. Geisler's promotional grant; the terms of the RSU and Performance Share awards are the same as the 2025 awards described above; the RSU and performance share grants were approved by the Committee on December 10, 2024 with the grants to be effective on April 1, 2025; additional information on Mr. Geisler's promotional grant is described in the Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table.

The Company does not have formal employment agreements with its NEOs; however, we typically enter into offer letters with new executive officers. Deferred compensation credits granted to Mr. Geisler and Mr. Tetlow are discussed under the heading “Discussion of Nonqualified Deferred Compensation” on page 90. The Company awarded Mr. Geisler a promotional long-term incentive award consisting of 70% Performance Share awards and 30% RSUs valued at $3,000,000 to be granted upon his promotion on April 1, 2025 and based upon the closing stock price on such date.

(15)This amount represents Mr. Tetlow's RSU promotional grant in October 2024 as part of his promotion (16) Mr. Geisler was awarded an additional promotional grant on April 1, 2025 in recognition of his promotion; the terms of the awards are the same as the 2025 awards described above.

  172. Retirement Plan and Supplemental Plan – Traditional Formula

    | Description | How it works | | Prior to April 1, 2003, benefits under the Retirement Plan and the Supplemental Plan (the "Traditional Formula Benefit") accrued in accordance with a traditional retirement plan formula based on average annual compensation and years of service (the "Traditional Formula"). Mr. Tetlow's benefits are calculated under the Traditional Formula. | A participant’s Traditional Formula Benefit under the Retirement Plan is a monthly benefit for life beginning at normal retirement age (age 65 with 5 years of service or age 60 with 33 years of service) and is equal to the participant’s average monthly compensation (the average of the highest 36 consecutive months of compensation in the final 10 years of employment) multiplied by 1.65% for the first 33 years of service, plus 1% of average monthly compensation for each year of service credited in excess of 33 years. Under the Traditional Formula of the Supplemental Plan, a participant's monthly benefit for life beginning at normal retirement age (age 65 or age 60 with 20 years of service) is equal to the following: •3% of the participant’s average monthly compensation (highest 36 consecutive months of compensation during employment) multiplied by the participant’s first 10 years of service, plus •2% of the participant’s average monthly compensation multiplied by the participant’s next 15 years of service, minus •benefits payable under the Retirement Plan. The total monthly Traditional Formula Benefit is capped at 60% of the participant’s average monthly compensation. A participant may elect to begin receiving a reduced Traditional Formula Benefit after attaining early retirement age (age 55 with 10 years of service). An actuarial reduction is applied to the Retirement Plan unless the participant has at least 20 years of service, in which case the reduction is 3% per year (prorated monthly) for each year prior to normal retirement. The reduction on the Supplemental Plan is 3% per year (prorated monthly). |

    (1)The amount of the executive contribution is solely from the voluntary deferral by the executive of the executive’s designated compensation and does not include any separate Company contribution. These deferred amounts are included in the “Salary” and “Non-Equity Incentive Plan Compensation” columns in the Summary Compensation Table. (2)A portion of the amounts reported in this column is the above-market portion of interest accrued under the deferred compensation plan (also reported as compensation in the Summary Compensation Table), including: Mr. Geisler — $12,126; Mr. Guldner — $50,916; Ms. Baum — $292; Mr. Heflin — $5,233; Mr. Tetlow — $28,956; and Mr. Smith— $51,035. (3)The historical contributions of each NEO to their aggregate balance as of December 31, 2025, including “market rate” interest (as defined by the SEC) from the date of each contribution, is as follows: Mr. Geisler — $202,377; Mr. Guldner — $1,609,775; Ms. Baum — $7,960; Mr. Heflin — $421,443; Mr. Tetlow — $350,052; and Mr. Smith — $2,441,577. Of the totals in this column, the following amounts have been reported in the Summary Compensation Table in this Proxy Statement or in the Company’s prior Proxy Statements: Mr. Geisler — $253,168; Mr. Guldner — $1,216,175; Ms Baum — $292; Mr. Heflin — $390,555; Mr. Tetlow — $320,482; and Mr. Smith— $1,775,906. (4)The terms of the Geisler and Tetlow DCP Discretionary Credits are discussed under “Discussion of the Nonqualified Deferred Compensation – DCP” below. (5)Supplemental RSUs were granted to Mr. Guldner in 2011 and vested over a four-year period, and earned additional Supplemental RSUs resulting from notional dividends on the vested underlying awards. The amount in the “Aggregate Balance at Last Fiscal Year End” column is calculated by multiplying the closing market price of our common stock at the end of 2025 ($88.70 per share) by the number of vested Supplemental RSUs (6,461).

  179. Potential Payments upon Termination or Change of Control

    Potential Payments upon Termination or Change of Control This section describes the potential payments that each of the NEOs could receive following termination of employment, including through death, disability, retirement, resignation, involuntary termination (with or without cause), or a change of control of the Company (each, a “Termination Event”). We describe plans, agreements, or arrangements under which each NEO could receive payments following a Termination Event, excluding those that do not discriminate in favor of our executive officers and that are available generally to all salaried employees, and awards that are already vested. The description of payments to the NEOs under the various Termination Event scenarios described in this section are not intended to affect the Company’s obligations to the NEOs. Those obligations are subject to, and qualified by, the contracts or arrangements giving rise to such obligations. The discussion below assumes that any Termination Event took place on December 31, 2025 for each NEO. The Company does not have a severance plan that covers the NEOs. We also do not have traditional severance agreements or arrangements with our NEOs. We do have Change of Control Agreements, which are discussed below. In addition to the termination payments set forth below, the NEOs would also receive a full distribution under the DCP and pension benefits. Amounts payable to Messrs. Geisler, Guldner, Heflin, Tetlow and Smith and Ms. Baum under the DCP are set forth in the Nonqualified Deferred Compensation table, which also shows which part of the payment is interest paid by the Company and which part is the executive’s contribution. The unvested Tetlow 2024 DCP Discretionary Credits would trigger a payment in connection with certain Termination Events, which are identified below. This agreement is discussed in the Discussion of Nonqualified Deferred Compensation. With respect to pension benefits, the amounts that each of the NEOs would receive under the Supplemental Plan in the event of a Termination Event are set forth in the Pension Benefits table. However, assuming that the NEO had died on December 31, 2025, the amounts payable under the Supplemental Plan would have been as follows: Mr. Geisler — $851,542; Mr. Guldner — $7,662,968; Mr. Cooper — $525,735; Ms. Baum — $248,735; Mr. Heflin — $861,483; Mr. Tetlow — $1,727,152; and Mr. Smith — $1,420,204. These amounts are based on the following assumptions: (1) the Traditional Formula Benefit is paid in the form of a monthly annuity to the NEO's spouse for life following his death and benefit payments commence when the NEO would have attained age 55; and (2) the Account Balance Formula is paid in the form of an immediate lump sum to their spouses. Messrs. Geisler, Guldner, Cooper, Heflin,Tetlow and Smith, and Ms. Baum would have received $818,093; $8,577,816; $495,602; $878,615; $1,298,020, $1,448,447 and $253,681 respectively, in the event of a Termination Event other than death, due on December 31, 2025, and these amounts are based on the assumption that the benefit would be payable in five-year installment payments beginning on January 1, 2026 for Mr. Guldner, Ms. Baum, Mr. Heflin and Mr. Smith, and beginning on June 1, 2027 (attainment of age 55) for Mr. Tetlow. The amounts for Messrs. Cooper and Geisler are based on the assumption that the benefit would be payable as a monthly annuity beginning on January 1, 2026 for Mr. Cooper and January 1, 2031 for Mr. Geisler (due to a change to his distribution election).

    With respect to the performance share awards, the recipient must remain employed with the Company throughout the performance period, unless the recipient meets any of the following exceptions, which would trigger a payment in connection with those certain Termination Events. In the case of the recipient’s retirement while qualifying for Early Retirement or Normal Retirement under the Retirement Plan (the “Retirement Qualified Employee”), the employee’s award will vest pro-rata based on the number of months employed during the performance period and the remaining grant forfeited (with payout based on actual performance results). Under all performance share awards, in the event the recipient is terminated for cause (regardless of the recipient’s retirement date), the recipient shall not be deemed to have been employed through the end of the performance period and will forfeit the right to receive any payout. In the event of death or disability, all employees will become vested in the award (with payout based on actual performance results). Under all performance share awards, in the event the recipient’s employment is terminated without cause during the performance period, the CEO, in his discretion and with the Committee’s approval, may determine if, to what extent, and when, any unvested portion of the grant may vest. The performance shares contain confidentiality protections that apply during employment and survive termination, and non-competition and employee solicitation restrictions that survive for a period of one year following termination of employment. With respect to RSUs, the recipient must remain employed with the Company through the applicable vesting date, unless the recipient meets any of the following exceptions, which would trigger a payment in connection with those certain Termination Events. For RSU awards granted in February 2022, if an employee meets the definition of a Retirement Qualified Employee at the time of grant, then upon that employee's retirement, the RSUs will fully vest and will be payable on the dates and in the percentages specified in the vesting schedule; for all other RSU awards granted after January 1, 2022 and thereafter, if a Retirement Qualified Employee retires, the recipient will receive payment for the first vesting following the retirement, which will be payable on the date and in the percentage specified in the vesting schedule; for all RSU awards granted after January 1, 2022 and thereafter, if any employee recipient dies or becomes disabled before the end of the vesting period, any outstanding RSUs will fully vest and will be payable no later than March 15 of the year following the year in which the event occurs. Under all RSU awards, in the event a recipient is terminated for cause, any award the recipient would otherwise be entitled to receive following the date of termination is forfeited. In the event a recipient is terminated without cause, the CEO, in his discretion and with the Committee’s approval, may determine if, and to what extent, any unvested portion of the grant will vest. The RSUs contain confidentiality protections that apply during employment and survive termination, and non-competition and employee solicitation restrictions that survive for a period of one year following termination of employment. As described in the next paragraph, if a recipient’s rights are adequately protected, a change of control will not result in any acceleration of a recipient’s performance shares or RSUs. However, if a change of control occurs and the conditions of the following paragraph are not met, immediately prior to the change of control, the RSUs and performance shares will convert to either cash or stock, at the election of the recipient, and shall immediately vest. In converting the performance shares, the recipient will receive the number of shares of stock or the cash equivalent that would have been earned at the target level of performance, unless the Committee determines that a higher level of attained performance is reasonably ascertainable as of a specified date prior to the closing of the change of control transaction. The dividend equivalent awards will be paid in cash or stock as determined in accordance with the applicable award agreement. Prior to a change of control, the Board may determine that no change of control shall be deemed to have occurred or that some or all of the enhancements to the rights of the recipient shall not apply to specified awards. The Board may exercise such override authority only if, before or immediately upon the occurrence of the specified event that would otherwise constitute a change of control, the Board reasonably concludes in good faith, that: (1) recipients holding awards affected by action of the Board override will be protected by legally binding obligations of the Company or the surviving entity or the parent thereof because such awards (A) shall remain outstanding following consummation of all transactions involved in or contemplated by such change of control, (B) shall be assumed and adjusted by the surviving entity resulting from such transactions or the parent thereof, or (C) shall be exchanged for new awards issued by the surviving entity resulting from such transaction or the parent thereof; and (2) changes in the terms of the award resulting from such transactions will not materially impair the value of the awards to the participants or their opportunity for future appreciation in respect of such awards.

  183. Potential Payments upon Termination or Change of Control

    The Company has entered into identical Change of Control Agreements with each of its executive officers, including each of the NEOs. The Company believes that these agreements provide stability for its key management in the event the Company experiences a change of control. The agreements contain a “double-trigger” that provides for certain payments if, during the two-year period following a change of control of the Company (the “first trigger”), the Company terminates the officer’s employment for any reason other than death, disability, or cause, or the executive terminates his or her own employment following a significant and detrimental change in the executive’s employment (the “second trigger”). In the case of an officer’s retirement, death, or disability, no payments are made under the officer’s Change of Control Agreement, except for the payment of accrued benefits; however, if the officer dies following the officer’s receipt of a second trigger termination notice, the officer’s estate will receive the change of control payments that the officer would have received had the officer survived. Pursuant to the Change of Control Agreement, each of the NEOs is obligated to hold in confidence any and all information in their possession as a result of their employment, during and after the NEO’s employment with the Company is terminated. The termination payment, if required, is an amount equal to 2.99 times the sum of the executive’s annual salary at the time of the change of control, plus the annual bonus (including incentive plan payments), as determined by an average over the last four years preceding termination. In addition, the executive is entitled to continued medical, dental, and group life insurance benefits at a shared cost until the end of the second year following the calendar year of termination. Outplacement services are also provided. If the limitations described in Section 280G of the Code are exceeded, the Company will not be able to deduct a portion of its payments. In addition, if these limitations are exceeded, Section 4999 of the Code imposes an excise tax on all or part of the total payments. In certain of the agreements, an additional gross-up payment equal to the excise tax (plus any penalties and interest) imposed on or with respect to the total payments is provided. In May 2009, the Company determined that, on a going-forward basis, it would no longer provide excise tax gross-up payments in new or materially amended agreements with its NEOs, but provided for an exception that gave the Company the ability to include a limited excise tax gross-up provision in connection with recruiting a new executive to the Company. In 2018, the Committee removed this exception. Since 2021, the Change of Control Agreements for all NEOs, except Mr. Guldner, contain a “best net benefit” provision which provides that the Company’s payments to the officer can be reduced to the extent that no portion of the reduced payments shall be subject to certain excise taxes under the Internal Revenue Code of 1986, but only if the officer’s net after-tax benefit is greater than his or her net after-tax benefit would have been if such reduction were not made and the officer paid the excise tax. A change of control under the Change of Control Agreement includes: (1) an unrelated third-party’s acquisition of 20% or more of the Company’s or APS’s voting stock; (2) a merger or consolidation where either the Company or APS combines with any other corporation such that (i) the Company’s or APS’s outstanding voting stock immediately prior to merger or consolidation represents less than 60% of the voting stock of the Company or APS immediately after the merger, or consolidation, or (ii) for all NEOs other than Mr. Guldner, less than a majority of the members of the board of directors of the parent following such merger or consolidation being members of the Company Incumbent Board (defined below) at the time of such Company Incumbent Board’s approval of the execution of the initial agreement providing for such merger or consolidation, but in both circumstances excluding a merger or consolidation effected to implement a recapitalization in which no unrelated third-party acquires more than 20% of the voting stock of the Company or APS; (3) a sale, transfer, or other disposition of all or substantially all of the assets of the Company or APS to an unrelated third-party; or (4) the case where the composition of either the Board of the Company or of APS changes such that the members of the Board of the Company (the “Company Incumbent Board”) or of APS (the “APS Incumbent Board”), as of June 23, 2021 (and with respect to Mr. Guldner as of July 31, 2008), no longer comprises at least two-thirds of the Company’s or APS’s Board of Directors. For purposes of this later provision, a person elected to either Board is treated as a member of the Company Incumbent Board or APS Incumbent Board if his or her nomination or election by shareholders was approved by a two-thirds vote of the members then comprising the Company Incumbent Board or APS Incumbent Board, and it does not include anyone who became a director in an actual or threatened election contest relating to the election of directors. Each of the agreements terminate on December 31st of each year upon six months’ advance notice by the Company to the executive officer; if the six months’ advance notice is not given, the agreements will continue for successive one-year periods until the notice is given. The Company is required to deposit sufficient funds into a trust to pay obligations under the DCP and the Supplemental Plan in the case of an actual or potential change of control.

  185. Potential Payments upon Termination or Change of Control

    The following tables quantify the amounts that would have been payable to each NEO if the indicated Termination Event had taken place on December 31, 2025. In the tables: •We assume full vesting of outstanding performance shares (at the target level) and RSUs upon a change of control. The performance shares and RSUs, plus, where applicable, dividend equivalents, for the NEOs vest upon a change of control whether or not there is a subsequent termination of employment (subject, however, to the Board’s ability to override the vesting). •Retirement benefits payable to Mr. Guldner include prorated vesting for awards (at the target level), full vesting of outstanding RSUs granted prior to 2023 and the next vesting of RSU awards granted in 2023 and thereafter, plus, in all cases where applicable, dividend equivalents. •Death or disability benefits payable to all NEOs include full vesting of performance shares (at the target level) and RSU awards, plus, in all cases where applicable, dividend equivalents. Subject to the foregoing, the following tables describe the amounts that would have been payable to each NEO if a Termination Event had taken place on December 31, 2025: Theodore N. Geisler:

  204. Pay Ratio

    Pay Ratio As required by Item 402(u) of Regulation S-K, we are providing the annual disclosure of the ratio of the median employee’s annual total compensation to the combined prorated total annual compensation of Mr. Guldner, our former CEO and Mr. Geisler, our current CEO, who each served as our CEO during 2025, non-concurrently. For 2025, the median of the annual total compensation of all employees of our Company (other than our CEO) was $182,127, and the combined prorated total annual compensation of our former CEO and current CEO, calculated based on the amounts reported in the Summary Compensation Table in this Proxy Statement, was $7,600,209. Based on this information and using the required calculation methodology defined in Item 402(u) of Regulation S-K, for 2025, the ratio of the annual total compensation of our CEO to our median employee’s annual total compensation was 42 to 1. As permitted by Item 402(u) of Regulation S-K, for fiscal year 2025 we used the same median employee for the pay ratio as was used for the pay ratio in the Proxy Statement for fiscal year 2023. We determined that during 2025, as compared to 2023, there were no material changes in our employee population or our employee compensation arrangements that we believe would significantly impact our pay ratio disclosure. To identify the median employee compensation from our employee population, as well as to determine the annual total compensation of our median employee and our CEO, we took the following steps: •We determined that, as of December 31, 2023, our employee population consisted of approximately 6,133 individuals, all of whom were located in the United States. This population consisted of our full-time, part-time, temporary, and seasonal employees.

  205. Pay Ratio

    | Table of Contents | Executive Compensation |

  206. Pay Ratio

    •To identify the median employee from our employee population, we compared the total amount of salary, wages, overtime, and premium pay, and an estimated cash incentive assuming a target payout under the 2023 Incentive Plans of our employees as reflected in our payroll records on December 31, 2023. •We identified our median employee using this compensation measure, which was consistently applied to all our employees included in the calculation. Since all our employees are located in the United States, as is our CEO, we did not make any cost-of-living adjustments in identifying the median employee. •We combined all of the elements of the median employee’s compensation for 2025 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $182,127. The difference between such employee’s salary, wages, overtime, and premium pay, and an estimated cash incentive assuming a target payout under the 2025 Incentive Plans and the employee’s annual total compensation includes the amount the Company contributed under the 401(k) plan for the employee, the actual amount paid under the 2025 Incentive Plans, and the estimated aggregate change in the actuarial present value from December 31, 2024 to December 31, 2025 of the employee’s accumulated benefits payable under all defined pension plans. •With respect to the annual total compensation of our CEO, since multiple individuals served as our CEO during 2025, we combined the prorated total compensation amount reported in the “Total” column of our 2025 Summary Compensation Table included in this Proxy Statement for each of our former CEO, Mr. Guldner, and our current CEO, Mr. Geisler, for the period of time they each held the position of CEO during 2025.

Abstentions will not be counted toward a nominee’s total and will have no effect on the election of Directors. You may not cumulate your votes against a nominee. If you hold shares in your own name and would like to exercise your cumulative voting rights, you must do so by mail. If you hold shares beneficially through a broker, trustee, or other nominee and wish to cumulate votes, you should follow the instructions provided by the broker, trustee or other nominee, as applicable.
