One area where we underperformed compared to our historical track record was in total shareholder return, which combines stock price appreciation with dividends paid, at 9% for the year. Increased regulatory uncertainty impacted shareholder confidence. Our new focus on ensuring robust communication and collaboration with the ACC and other stakeholders has already put us on a more positive path forward. We believe we have the right strategy and team in place to meet your expectations for delivering consistent shareholder value. * Periods ending December 31, 2019 2020 Proxy Statement 3 Deliver value-added programs and services that derive from consumer insights and strengthen our brand for the future Table of Contents PROXY STATEMENT SUMMARY

SHAREHOLDER RECOMMENDATION OF BOARD CANDIDATES FOR THE 2020 ANNUAL MEETING Shareholder nominations for a director to the Board must be received by the Corporate Secretary at the address set forth below by November 20, 2020 Annual Meeting Shareholder nominations for a director to the Board must be received by the Corporate Secretary at the address set forth below by November 22, 2019 (“Shareholder Nomination”): Corporate Secretary Pinnacle West Capital Corporation 400 North Fifth Street, Mail Station 8602 Phoenix, Arizona 85004 Proxy Access 18 Table of Contents INFORMATION ABOUT OUR BOARD AND CORPORATE GOVERNANCE PROXY ACCESS In February 2017, our Board amended the Bylaws to provide, among other things, that under certain circumstances a shareholder or group of shareholders may include director candidates that they have nominated in our annual meeting proxy statement — “proxy access”. Under these provisions, a shareholder or group of up to 20 shareholders seeking to include director nominees in our annual meeting proxy statement must own 3% or more of our outstanding common stock continuously for at least the previous three years. Generally, the number of qualifying shareholder-nominated candidates the Company will include in its annual meeting proxy materials will be limited to the greater of 25% of the Board or two candidates. Based on the current Board size of 12 directors, the maximum number of proxy access candidates we would be required to include in our proxy materials is three. Nominees submitted under the proxy access provisions that are later withdrawn or are included in the proxy materials as Board-nominated candidates will be counted in determining whether the 25% maximum has been reached. If the number of shareholder-nominated candidates exceeds 25%, each nominating shareholder or group of shareholders may select one nominee for inclusion in our proxy materials until the maximum number is met. The order of selection would be determined by the amount (largest to smallest) of shares of our common stock held by each nominating shareholder or group of shareholders. Requests to include shareholder-nominated candidates under proxy access must be received by our Corporate Secretary at the address set forth above not earlier than the close of business on November 7, 2020 nor later than the close of business on December 7, 2020. The number of qualifying shareholder-nominated candidates the Company will include in its proxy materials under proxy access will be reduced on a one-for-one basis in the event the Company receives a Shareholder Nomination, but at least one qualifying shareholder-nominated proxy access nominee will be included in the proxy materials. In all cases, shareholders and nominees must also comply with the applicable rules of the SEC and the applicable sections of our Bylaws relating to qualifications of nominees and nominating shareholders and disclosure requirements. Board Effectiveness Board Refreshment Planning Our Board has developed a robust plan to refresh the Board and its leadership significantly over the next several years and beyond. The plan is designed to continue to provide for a well-qualified, diverse and highly independent Board, with the requisite experience and skills to provide effective oversight. This plan includes the identification of the current key skills and experience possessed by our members. A matrix of current key skills and experience possessed by our Board is on page 12. The identification of these skills and experiences, combined with a comprehensive Board evaluation process, provide visibility into the skills and experience leaving our Board in the future and allows for the identification of additional skills, experience or expertise needed to facilitate the Company’s long-term strategy. This information is taken into account when identifying director nominees during the recruitment process. Board refreshment is overseen by the Corporate Governance Committee, which regularly assesses whether the composition of the Board reflects the knowledge, skills, expertise, and diversity appropriate to serve the needs of the Company. 2020 Proxy Statement 19 Table of Contents INFORMATION ABOUT OUR BOARD AND CORPORATE GOVERNANCE Director Retirement Policy Under the Company’s Corporate Governance Guidelines, an individual was not eligible to be nominated for election or re-election as a member of the Board of the Company or APS if, at the time of the nomination, the individual has attained the age of 75 years. In February 2020, we reevaluated our Director Retirement Policy. The policy as drafted could result in long tenure solely by virtue of the person’s age when he or she joined the Board. As such, we amended the policy to add a 12-year term limit in addition to an age limit. The new policy provides that a non-employee Director will not be eligible to be nominated for election or re-election as a member of the Board if, as of the commencement of the term for which they are nominated, such Director will have (i) completed 12 years of service from the date of first election to the Board or (ii) attained 75 years of age. We also added a provision that will allow the Board, if it determines that it is in the best interest of the Company to do so, to extend such term limit to up to 15 years for a particular nominee, so long as the average tenure of the overall Board is less than 10 years. We believe this combination of both a term and age limit creates the most robust and effective policy. We were also concerned about the turn-over rate of the Board members under the age-only policy in light of the Company having a newly appointed CEO. Under the age only policy, we would experience multiple years with more than one member scheduled to retire. We believe that it is in the best interests of the Company to better stagger these retirements while Jeff gets more experience in the CEO role. As such, we created a transition period that slowed the immediate turn-over rate, but provided a bridge to the final policy. Through and until the 2024 Annual Meeting of Shareholders, a non-employee Director shall be eligible for nomination for election or re-election as a member of the Board unless, as of the commencement of the term for which they are nominated, such Director will have completed 12 years of service from the date of first election to the Board and the individual has attained 75 years of age. During both the transition period and the time covered by the final policy, the policies will apply regardless of the source of the nomination or whether the nomination was made at a meeting of the Board of Directors, at an Annual Meeting or otherwise. Directors added or retired since the adoption of our Director Retirement Policy: 20%of our Board has been refreshed Since the adoption of our Director Retirement Policy, three independent Directors have been added and two members of the Board will have retired as of May 20, 2020. Under our current policy, over 50% of our current Board will retire by the 2025 Annual Meeting of Shareholders. Average tenure decreased by22%since 2016 Our average tenure decreased from 12.2 years as of May 2016 to 9.5 years as of May 2020. 20 Table of Contents INFORMATION ABOUT OUR BOARD AND CORPORATE GOVERNANCE OUR BOARD EVALUATION PROCESS 1 Board Evaluation Each Director completes a comprehensive evaluation of Board and Committee performance Reviewed on a one-year stand-alone basis and three-year basis to identify year-over-year trends Topics covered include, among others: ●Board composition and effectiveness ●Competency and accountability ●Deliberations and administration ●Committee effectiveness ●Specific skills, experience and expertise recommended by Directors to be added or two candidates. enhanced 2 Director Self-Evaluation Each Director evaluates different areas of his or her performance as a Director Topics covered include, among others: ●Independence ●Knowledge and expertise ●Judgment and skills ●Participation and contribution to collective decision-making 3 One-on-One Discussions Conducted by Lead Director, who initially reviews the assessment results, in a formal annual call The Lead Director is prepared to have hard conversations, if necessary, to keep the Board, and each individual Director, functioning at a high level Topics covered include, among others: ●The Board, its functions and membership ●Board and Committee structure ●Processes for effective communication and feedback ●Director’s plan with respect to continuing Board service ●Any other topic the individual Director desires to discuss 4 Evaluation Results The results of the evaluations and calls are presented to the Corporate Governance Committee and full Board each February 5 Feedback Incorporated Based on the current Board size of 11 directors,evaluation results, changes in practices or procedures are considered and implemented as needed This process provides the Board the ability to assess the overall functioning of the Board as a whole, and identify any skills, experience or expertise needed to continue to provide effective oversight of the Company’s long-term strategy. This process also allows the Board to identify any areas of concern, both with respect to the Board overall and with respect to individual performance. As performance issues are identified, they are addressed by the Lead Director and the Chairman as needed. Director Onboarding Upon election to the Board, all new Directors attend a Director orientation program tailored to each Director based on their past individual experience. After Mr. Trevathan was elected to the Board, he received detailed information and materials about our Company, business and operations. He attended an orientation that took place over several days and included meetings with management from multiple business units, presentations on topics of significance to the Company and our industry, and site visits to our Deer Valley customer service and operations facility as well as the Palo Verde Generating Station. A similar orientation is in process for Ms. Bryan. 2020 Proxy Statement 21 Table of Contents INFORMATION ABOUT OUR BOARD AND CORPORATE GOVERNANCE Director Education Directors are provided with continuing education opportunities both within the Company and externally. In addition to the Company-hosted educational opportunities provided, Directors are invited to attend Palo Verde Off-Site Safety Review Committee meetings that typically occur three times per year, site visits to a number of our plants and other facilities are arranged, and Directors are encouraged to attend a variety of industry and public board-related symposia and conferences throughout the year. Additionally, Directors are permitted to participate in other educational opportunities relevant to the Company and submit such record of attendance for credit in our program. Director Resignation Policies We employ a plurality voting standard with a director resignation policy because we believe a majority voting policy is inconsistent with cumulative voting, which is mandated by the maximum number of proxy access candidates we would be required to include in our proxy materials is two.Arizona Constitution. With respect to the election of directors, the Company’s Bylaws provide that in an uncontested election, a director nominee who receives a greater number of votes cast “withheld” for his or her election than “for” such election will promptly tender his or her resignation to the Corporate Governance Committee. The Corporate Governance Committee is required to evaluate the resignation, taking into account the best interests of the Company and its shareholders, and will recommend to the Board whether to accept or reject the resignation. Under the Company’s Corporate Governance Guidelines, upon a substantial change in a director’s primary business position from the position the director held when originally elected to the Board, a director is required to apprise the Corporate Governance Committee and to offer his or her resignation for consideration to the Corporate Governance Committee. The Corporate Governance Committee will recommend to the Board the action, if any, to be taken with respect to the tendered resignation.

Information about100% attendance rate in 2019 Board Oversight and Engagement Strategic Framework The Core serves as the foundation for all strategic and business initiatives. It is anchored by four pillars that establish the foundation for the way we intend to do business: Clean, Affordable, Reliable and Customer Focused. Our Board reviews the strategic business plan annually and oversees the implementation of that strategy, receiving regular reports from management on progress and any changes throughout the year. The Board, through the Human Resources Committee, is also involved in setting the annual performance metrics, which are aligned with the strategic plan and designed to incentivize achievement of the strategic goals. CORE The Company and APS have adopted Core, which is a strategic framework that sets forth the foundation from which we operate. It defines our vision, mission, critical areas of focus, and values.

Director Resignation Policies We employ a plurality voting standard with a director resignation policy because we believe a majority voting policy is inconsistent with cumulative voting, which is mandated by the Arizona Constitution. With respect to the election of directors, the Company’s Bylaws provide that in an uncontested election, a director nominee who receives a greater number of votes cast “withheld” for his or her election than “for” such election will promptly tender his or her resignation to the Corporate Governance Committee. The Corporate Governance Committee is required to evaluate the resignation, taking into account the best interests of the Company and its shareholders, and will recommend to the Board whether to accept or reject the resignation. UnderThe Core ties together many critical components to ensure that we have a customer-focused culture and deliver operational excellence. Our ability to thrive and grow as a company depends on the Company’s Corporate Governance Guidelines, upon a substantial change in a director’s primary business position fromtrust and goodwill of our customers and the position the director held when originally elected to the Board, a director is required to apprise the Corporate Governance Committeecommunities we serve. We recruit and to offer his or her resignation for consideration to the Corporate Governance Committee. The Corporate Governance Committee will recommend to the Board the action, if any,retain great people, and we empower them to be taken with respectenthusiastic ambassadors for our customers. We respond to the tendered resignation.customer needs by developing new and innovative solutions to help them manage their own energy use. By pursuing this customer-centric culture, we create customer value that, in turn, builds shareholder value. Other Matters Codes of Ethics and APS Core Strategic Framework To ensure the highest levels of business ethics, the Board has adopted the Code of Ethics and Business Practices, which applies to all employees, officers and directors, and the Code of Ethics for Financial Executives, both of which are described below: CODE OF ETHICS AND BUSINESS PRACTICES (“CODE OF ETHICS”)2020 Proxy Statement Employees, directors and officers receive access to and training on the Code of Ethics when they join the Company or APS, as well as annual updates.

The Nuclear and Operating Committee has primary responsibility over environmental matters, though the Board also receives reports on matters of environmental importance. Another key focus of the Board is the adoption and maintenance of good governance practices, which is a primary responsibility of the Corporate Governance Committee.

These rules describe certain relationships that prevent a director from being independent and require a company’s board of directors to make director independence determinations in all other circumstances. The Company’s Board has also adopted Director Independence Standards to assist the Board in making independence determinations. These Director Independence Standards are available on the Company’s website(www.pinnaclewest.com). Ten of our eleven directors are independent. Based on the Board’s review, the Board has determined that one of the Company’s directors is not independent and that all of the other directors are independent. The current independent directors are Messrs. Fox, Gallagher, Lopez, Nordstrom, Trevathan, and Wagener, Drs. Cortese and Klein, and Mses. Munro and Sims. Mr. Herberger was independent while he was a member of the Board. Mr. Brandt is not independent under the NYSE rules or the Director Independence Standards because of his employment with the Company. In accordance with the NYSE rules and the Director Independence Standards, the Board undertakes an annual review to determine which of its directors are independent. The review generally takes place in the first quarter of each year; however, directors are required to notify the Company of any changes that occur throughout the year that may impact their independence. Dr. Cortese is independent under the tests imposed by the NYSE rules and our Director Independence Standards. Dr. Cortese is an employee of Arizona State University (“ASU”) in his capacity as the Director of the ASU Health Care Delivery and Policy Program and a Foundation Professor in the Department of Biomedical Informatics, Ira A. Fulton School of Engineering and in the School of Health Management and Policy, W.P. Carey School of Business. ASU is considered a part of the reporting entity for the State of Arizona (the “State”) for financial reporting purposes and, as such, the State is the entity considered in applying the independence tests. In considering the independence of Dr. Cortese, the Board considered the fact that transactions between the State and the Company and its affiliates consist of providing electric service, the payment of various State fees, taxes, memberships, licenses, sponsorships and donations, and the payment by each party of utility-related costs. The Board determined that these matters do not impact Dr. Cortese’s independence, since amounts paid to or received from the State are less than the dollar thresholds set forth in the NYSE rules and the Director Independence Standards. In addition, Dr. Cortese did not and does not benefit, financially or otherwise, directly or indirectly, from ASU’s business relationships with the Company, most of which consist of receiving electric service at regulated rates. Mr. Fox is independent under the tests imposed by the NYSE rules and our Director Independence Standards. Mr. Fox serves as a director of Univar, Inc. APS purchases chemicals that are used in the operation and maintenance of our power plants, primarily in controlling our water chemistry, from Univar. However, since: (a) the amounts paid to Univar were less than the dollar thresholds set forth in the NYSE rules and our Director Independence Standards and were less than one percent of the Company’s and Univar’s revenues for fiscal year 2018; (b) the relationship between APS and Univar pre-dates Mr. Fox joining the Board; and (c) our purchases from Univar are negotiated at arm’s length, the Board determined that these transactions do not impact Mr. Fox’s independence. 38      Table of Contents Director Nominees for the 2019 Annual Meeting Mr. Gallagher is independent under the tests imposed by the NYSE rules and our Director Independence Standards.

Mr. Trevathan is independent under the tests imposed by the NYSE rules and our Director Independence Standards. Mr. Trevathan was Executive Vice President and Chief Operating Officer of Waste Management at the time of his election to the Board on December 19, 2018 until his retirement from Waste Management on December 31, 2018. Waste Management provided services to the Company in 2016, 2017, and 2018; however, since the amounts paid to and from Waste Management during each of those years were less than the dollar thresholds set forth in the NYSE rules and the Director Independence Standards, and were less than one percent of the Company’s and Waste Management’s revenues for each year respectively, the Board determined that Mr. Trevathan was independent while he was employed by Waste Management. Now that Mr. Trevathan is retired, the dollar threshold test no longer applies. As such, the Board determined that Mr. Trevathan continues to be independent.

CURRENT DIRECTORS NOT STANDING FOR REELECTION Mr. Michael L. Gallagher will retire from the Board effective at the Annual Meeting. The Board recognizes Mr. Gallagher’s distinguished service over the years and thanks him for his tireless labor, devotion and service to the Company. 2020 Proxy Statement 43 Table of Contents DIRECTOR NOMINEES FOR THE 2020 ANNUAL MEETING Director Independence NYSE rules require companies whose securities are traded on the NYSE to have a majority of independent directors. These rules describe certain relationships that prevent a director from being independent and require a company’s board of directors to make director independence determinations in all other circumstances. The Company’s Board has also adopted Director Independence Standards to assist the Board in making independence determinations. These Director Independence Standards are available on the Company’s website (www.pinnaclewest.com). In accordance with the NYSE rules and the Director Independence Standards, the Board undertakes an annual review to determine which of its directors are independent. The review generally takes place in the first quarter of each year; however, directors are required to notify the Company of any changes that occur throughout the year that may impact their independence. Based on the Board’s review, the Board has determined that all of the Company’s Directors and Director nominees are independent, except Mr. Guldner due to his employment with the Company. Mr. Brandt was not independent while he was on the Board due to his employment with the Company. 11 of our 12 Directors are independent The Company has purchase, sale and other transactions and relationships in the normal course of business with companies with which certain Company Directors are associated but which the Board determined are not material to our Company, the Directors or the companies with which the Directors are associated. These transactions were reviewed and considered by the Board in determining the independence of Company Directors. In particular, the Board took into account the following transactions during fiscal year 2019: ● Ms. Bryan is an executive officer of Insight Enterprises, Inc. (“Insight”), which provides computer hardware and software products and IT services to APS. The amounts paid to Insight represent less than 1% of the independenceCompany’s and Insight’s total annual revenues; ● Dr. Cortese is an employee of any director.Arizona State University, which is considered a part of the reporting entity for the State of Arizona (the “State”) for financial reporting purposes. During fiscal year 2019, various transactions occurred between the State and the Company and its affiliates, such as the provision of electric service, the payment of various State fees, taxes, memberships, licenses, sponsorships and donations, and the payment by each party of utility-related costs. The Board also considered contributionsamounts paid to charitable and non-profit organizations where a director alsoreceived from the State represent less than 2% of the State’s total annual revenues; and ● Mr. Fox serves as a director of such charity or organization. However, since no director is also an executive officerUnivar Solutions, Inc. (“Univar”), from which APS purchases chemicals that are used in the operation and maintenance of such charitable or non-profit organization,our power plants. The amounts paid to Univar represent less than 1% of the Board determined that these payments did not impact the independence of any director. Board MeetingsCompany’s and AttendanceUnivar’s total annual revenues. The Board believes that all of the transactions and relationships during fiscal year 2019 described above were on arm’s-length terms that were reasonable and competitive and that the Directors did not participate in or receive any direct personal benefit from these transactions. In addition, with respect to all of the Directors, the Board considered that many of the Directors and/ or businesses of which they are officers, Directors, shareholders, or employees are located in APS’s service territory and purchase electricity from APS at regulated rates in the normal course of business. The Board considered these relationships in determining the Directors’ independence, but, because the rates and charges for electricity provided by APS are fixed by the ACC, and the Directors satisfied the other independence criteria specified in the NYSE rules and the Director Independence Standards, the Board determined that these relationships did not impact the independence of any Director. The Board also considered contributions to charitable and non-profit organizations where a Director also serves as a director of such charity or organization. However, since no Director is also an executive officer of such charitable or non-profit organization, the Board determined that these payments did not impact the independence of any Director. 44 In 2018 each of our directors except for one attended 95% of the Board meetings and any meetings of Board committees on which he or she served. In 2018, our Board held seven meetings and each of our directors, except for one, attended 95% of the Board meetings and any meetings of Board committees on which he or she served. Each director is expected to participate in the Annual Meeting. One of our directors was not able to participate in the February meetings due to being involved in a serious accident a few days prior to those meetings. However, the director did attend all other Board meetings and any meetings of Board committees on which he served, putting his 2018 attendance percentage at 86%. All Board members attended the 2018 Annual Meeting. 2019 Proxy Statement     38 Table of Contents DIRECTOR NOMINEES FOR THE 2020 ANNUAL MEETING Director Compensation Compensation of the directors for 2019 was as follows: Name      Fees Earned or Paid in Cash ($)      Stock Awards ($)(1)      Change in Pension Value and Nonqualified Deferred Compensation Earnings ($)(2)      All Other Compensation ($)      Total ($) Donald E.

The 2012 Long-Term Incentive Plan, as amended (the “2012 Plan”), was amended in 2017 to add an overall limit to non-employee directors’ compensation. Thea value of equity grants (basedapproximately $120,000 on the grant date value) plus the aggregate amount of cash fees earned or paid is limited to $500,000 per calendar year. A comparison against the compensation programs of a peer group is generally performed every two years, and a study was last performed in December 2017 using the peer group that we used in setting 2018 executive compensation. At that time the Board approved increasing the value of the annual retainer from $100,000 to $105,000, the annual equity grant from $110,000 to $120,000, the committee chair retainers from $12,500 to $15,000 including instituting a committee chair retainer for the chair of the Corporate Governance Committee, and the Lead Director annual retainer from $25,000 to $30,000. Directors had an option to either receive the stock grant on May 15, 2019 or defer the receipt until a later date. A director who elected to defer his or her receipt of stock received SUs in lieu of the stock grant. Those directors who elected to receive SUs were able to elect to receive payment for the SUs in either: (1) stock; (2) 50% in stock and 50% in cash; or (3) cash. The directors also elected whether to receive these payments either as of the last business day of the month following the month in which the director separates from service on the Board, or as of a date specified by the director, which date must be after December 31 of the year in which the grant was received.

The manner of payment for the dividends and interest will be based on the director’s election for payment of the SUs.

At that time the Human Resources Committee and Board deferred deciding on any changes to the compensation for the Board to a later date to allow for further deliberation. The last adjustment to Directors’ compensation was in December 2017 when the Board approved increasing the value of the annual retainer from $100,000 to $105,000, the annual equity grant from $110,000 to $120,000, the committee chair retainers from $12,500 to $15,000, the Lead Director annual retainer from $25,000 to $30,000, and instituted a committee chair retainer for the chair of the Corporate Governance Committee. These changes went into effect in May 2018. The Consultant, as defined in the Compensation Discussion and Analysis, reviewed the study, validated the methodology, and concluded that the new amounts were within the competitive range. 46 Table of Contents DIRECTOR NOMINEES FOR THE 2020 ANNUAL MEETING Director Stock Ownership Policy The Company believes that directors should have a meaningful financial stake in the Company to align their personal financial interests with those of the Company’s shareholders. In December 2019, the Board amended the Company’s stock ownership policy for non-management directors to increase the holding requirement. Each director is required to hold or control Company common stock, RSUs, or SUs with a value of at least five times the annual cash retainer fee paid to directors. Directors will have three years from the date of the adoption of the amendment to meet the new requirement; newly elected directors will have six years following the date they become a director to reach the required ownership level. The Corporate Governance Committee may grant exceptions to this policy for hardship or other special circumstances. Directors may not engage in any speculative trading, hedging, or derivative security transaction (including any financial instrument such as a prepaid variable forward contract, equity swap, collar, short-sales, or exchange fund) that involves or references Company securities. In addition, Directors may not pledge, margin or otherwise grant an economic interest in any shares of Company stock. All of the Directors are in compliance with the Director Stock Ownership Policy. 2020 Proxy Statement 47 Table of Contents EXECUTIVE COMPENSATION PROPOSAL 2 Advisory Vote on Executive Compensation The Board of Directors unanimously recommends a vote FOR the approval of the Company’s executive compensation Section 14A of the Exchange Act requires U.S. public corporations to provide for an advisory (non-binding) vote on executive compensation. As discussed in more detail in our CD&A and the accompanying tables and narrative, the Company has designed its executive compensation program to align executives’ interests with those of our shareholders, make executives accountable for business and individual performance by putting pay at risk, and attract, retain and reward the executive talent required to achieve our corporate objectives and to increase long-term shareholder value. We believe that our compensation policies and practices promote a pay at risk philosophy and, as such, are aligned with the interests of our shareholders. In deciding how to vote on this say-on-pay proposal, the Board points out the following factors, many of which are more fully discussed in the CD&A: ● Our Human Resources Committee has designed the compensation packages for our NEOs to depend significantly on putting pay at risk by tying pay to the achievement of goals that the Human Resources Committee believes drive long-term shareholder value; ● Our pay practices are designed to encourage management to not take unacceptable risks; ● We engage in periodic structural reviews of our compensation programs and policies; and ● We believe that the Company’s executive compensation program is well suited to promote the Company’s objectives in both the short- and long-term. The Board endorses the Company’s executive compensation program and recommends that the shareholders vote in favor of the following resolution: RESOLVED, that the compensation paid to the Company’s Named Executive Officers as disclosed in this Proxy Statement in the CD&A, the compensation tables and the narrative discussion, is hereby approved.

Through our principal subsidiary, APS, we provide retail electricity service to 1.2 million customers in 11 of Arizona’s 15 counties. Clean energy plays a vital role in meeting our customers’ energy needs, and today 50% of our diverse energy mix today comes from clean, carbon-free resources. Our clean energy resources include growing renewables, primarily solar, and nuclear from the nation’s largest source of carbon-free energy, Palo Verde Generating Station. Palo VerdeStation provides nearly70%of Arizona’s carbon-free energy and uses recycled wastewater to cool the plant. Palo Verde is the nation’s largest power producer of any kind and has been for 27 consecutive years. We are making targeted investments in battery storage, flexible generation and renewables that will help deliver more clean energy to customers, as well as energy management systems that enable the energy grid to function more efficiently and intelligently. These technologies work together to provide customers with greater choice while maintaining reliability and enhancing our flexibility to meet Arizona’s energy needs. Between our CEO and our Executive Vice Presidents, we have more than 150 combined years Clean energy plays a vital role in meeting our customers’ energy needs, and today 50% of our diverse energy mix comes fromclean, carbon-free resources. The Company has been on a trajectory of increasingly clean energy through solar power innovation, major investments in energy storage technology, carbon-free nuclear operations and advances in energy efficiency solutions. Now, we are accelerating and solidifying that path with a goal to deliver 100% clean, carbon-free and affordable electricity to customers by 2050. We will rely on intelligent investments in renewable resources, continued modernization of experience in the energy industry, including relevant specialized nuclear experience. In particular, while we share ownership of Palo Verde, APS retains full day-to-day operational responsibility. This responsibility includes regulatory responsibility to the NRC. As such, the grid and the nuclear power produced at Palo Verde Generating Station, the nation’s largest carbon-free energy resource, to sustain reliability and affordability on the pathway to the 100% goal. While we share ownership of Palo Verde, APS retains full day-to-day operational responsibility, including regulatory responsibility to the NRC. The complexity of running a nuclear plant of Palo Verde’s size of Palo Verde and the complexity of running a nuclear plant of this magnitude requires a highly specialized and experienced management team. Given our need for specialized experience within our organization, we maintain strong succession planning practices and are focused on developing and retaining talent within our Company. Our Board’s focus on attracting, developing and retaining highly skilled and experienced executives is a core consideration in structuring our executive compensation programs.

Although our total shareholder value underperformed, we achieved the following accomplishments in 2019, among others: ● Total shareholder value increased $889.2 million in 2019, $2.4 billion over the past three years, and longest-serving$4.0 billion over the past five years; ● Our TSR was 9.0%, 12.9%, 27.2% and 56.2% for the past one, two, three and five-year periods respectively; ● Pinnacle West increased its dividend for the 8th consecutive year, by 6% in 2019; ● APS finished top quartile relative to peer electric company, we’re proudutilities for OSHA recordable injury events; ● Pinnacle West was named to the Climate Change and Water Security “A Lists” by global environmental impact nonprofit CDP, the only U.S. electric utility and just 1 of our heritage10 U.S. companies with A’s in both categories; and performance.

Under the leadership of the senior officer team, since 2009 Palo Verde Generating Station has become one of the top performing nuclear power plants in the U.S., and we have seen strong, sustained gains in shareholder returns and significant improvements in our credit rating. During 2018 we continued to deliver strong performance: ● Total shareholder value increased $341 million in 2018, $3.3 billion over the last three years, and $5.1 billion over the last five years; ● Our TSR for 2018 was 3.6%; since May 1, 2009, Pinnacle West has delivered an annualized TSR of 17.1%, exceeding the annualized returns of the S&P 1500 Electric Utilities Index of 11.1% and the S&P 500 Index of 13.9%; ● Pinnacle West increased its dividend for the 7th consecutive year, by 6% in 2018; ● 2018 was another successful year for APS with regard to security with a nearly 50% reduction in physical security false alarms since 2016; ● Pinnacle West obtained an Environmental Sustainability and Governance “A” rating from MSCI (as of November 6, 2018); and ● Palo Verde Generating Station received the 2018 North American ISOE (International System on Occupational Exposures) World Class ALARA Performance Award, which recognizes Palo Verde’s radiological protection teamwork and radiation safety program as the best in North America and among the best in the world. Shareholder Engagement and Board Responsiveness SHAREHOLDER ENGAGEMENTMeasurement Period We have an established shareholder outreach program to maintain a dialogue with our shareholders, and feedback from our shareholders informs our Human Resources Committee’s (for purposes of this CD&A, the “Committee”) actions. In 2018 we continued our robust outreach program by: ● Contacting the holders of more than 50% of shares outstanding, including many of our largest institutional shareholders as well as smaller holders to collect a range of perspectives; and ● Seeking direct feedback from shareholders on our compensation program, governance, sustainability and environmental objectives. BOARD RESPONSIVENESSPerformance Link Shareholder input is very valuable to the Board’s decision-making. As you may recall, in 2017 we were disappointed with our say-on-pay vote. We reached out to our shareholders to hear their concerns, particularly with respect to our executive compensation program, and to address them. We made the following changes in response to that shareholder feedback: ● We increased the proportion of performance shares in our CEO’s and Executive Vice Presidents’ annual long-term incentive awards from 60% to 70% beginning in 2018; ● We revised metrics in certain key business units to better align with our priorities and emphasize top quartile performance and/or improve on historical trends for 2018; ● We reflected the August 2017 approval of our comprehensive rate review in our earnings goals and represented a meaningful year-over-year increase in the 2018 earnings goal; ● We adopted a formal clawback policy covering short- and long-term incentive awards beginning in 2018; and ● We streamlined our compensation-related disclosure and provided additional disclosure around our goal setting processes and Committee decisions, the 2017 CEO Performance Contingent Award, and our succession planning process. 2019 Proxy Statement     45 Description Table of Contents Executive CompensationCash These changes were well received by our shareholders and in 2018 our say-on-pay vote received a “for” vote of 93%.

Hatfield’s, Bement’s, Froetscher’s, Guldner’s and Schiavoni’s base salary between 3.9%-9.5%. Mr. Froetscher also received a promotional increase in February of 2018 in recognition of his advancement to Executive Vice President, Operations of APS. 2018 ANNUAL INCENTIVE AWARD Our 2018 annual incentive performance goals were set within the context of the business and economic circumstances known at that time. As a regulated utility, we are generally unable to adjust our base retail prices outside of a rate case. As such, in years in which we do not expect a retail rate adjustment, changes in our revenues over the previous year would depend largely on factors beyond our control, such as customer growth, weather and customer usage patterns. However, our 2018 earnings goals reflected the approval of our 2017 retail rate adjustment and thus represented a meaningful year-over-year increase in the target. We set the APS 2018 earnings target at $512 million for 2018, representing a 6% increase over 2017 actual incentive earnings of $483.8 million. Likewise, we set Pinnacle’s 2018 target earnings range such that its projected midpoint was $493 million, representing a 4% increase over Pinnacle’s 2017 actual incentive earnings of $475.4 million. Earnings for APS and Pinnacle West for incentive plan purposes were 5% and 4% above the 2018 targets, respectively as shown on pages 58 and 57. The improvement in 2018 earnings was driven in part by effective cost controls and higher revenues. 2019 Proxy Statement     47 Table of Contents Executive CompensationCash The 20181 year Earnings Former CEO(1): 62.5% Current CEO(1): 50.0% Other NEOs: 50.0% Universal measure of business financial performance; encourages achievement of bottom-line earnings growth goals.

EXECUTIVE COMPENSATION ENHANCEMENTS We are committed to actively engaging with our shareholders and to make changes to our compensation program to ensure that it represents our strong commitment to our pay-for-performance philosophy. Over the past several years, we have undertaken the following enhancements: Enhanced Rigor of Performance-Based Plans ● Increased relative TSR-based performance share outperformance for target vesting to the 55th percentile or higher (up from the 50thpercentile) for our CEO and Executive Vice Presidents, starting with the 2020 grant. Increased Percentage of At-Risk Compensation ● Performance shares for our CEO and Executive Vice Presidents have increased from 55% of long-term incentive to 70% of long-term incentive since 2016 Changes to CEO Compensation ● Discontinued the use of a separate CEO incentive plan to simplify reporting across the executive team starting in 2020 ● Lowered CEO target amount to 110% of base salary from previous midpoint of 125% of base salary ● Committed to no further CEO retention grants for Mr. Brandt Adopted Clawback Provisions ● Adopted a formal clawback policy covering short- and long-term incentive awards beginning in 2018, with separate clawback provisions added to performance shares and annual incentive plan awards in 2016 2020 Proxy Statement 53 Table of Contents EXECUTIVE COMPENSATION In the spring of 2019, we committed to make some of the changes to our compensation program as highlighted above. These changes were well-received by our shareholders and in 2019 our say-on-pay vote received a “for” vote of 96%. Given the shareholder support of our compensation program that was evidenced by the 2019 vote results, we implemented the changes we had committed to making but we didn’t make any additional changes to our compensation program as a result of the say-on-pay vote. KEY 2019 COMPENSATION DECISIONS For fiscal year 2019, the Human Resources Committee (for purposes of the CD&A, the “Committee”), or the Board acting on the Committee’s recommendation, approved the following compensation for our NEOs: 2019 BASE SALARY ADJUSTMENTS For fiscal year 2019, the Committee increased Mr. Brandt’s salary by 3.2% and the Board, acting on the Committee’s recommendation, increased Messrs. Hatfield’s, Bement’s, Froetscher’s and Smith’s base salary between 3.2%-9.1%. Mr. Guldner also received promotional increases in January and November of 2019 in recognition of his advancements to Executive Vice President, Public Policy of PNW and President of APS and then to Chairman of the Board, President and Chief Executive Officer of PNW and Chairman of the Board and Chief Executive Officer of APS, respectively. 2019 ANNUAL INCENTIVE AWARD Our 2019 annual incentive performance goals were set within the context of the business and economic circumstances known at that time. As a regulated utility, we are generally unable to adjust our base retail prices outside of a rate case. As such, in years in which we do not expect a retail rate adjustment, changes in our revenues over the previous year would depend largely on factors beyond our control, such as customer growth, weather and customer usage patterns. Consistent with this methodology, we set the APS earnings target at $538 million for 2019, relatively flat to the 2018 actual incentive earnings of $537.2 million. Likewise, we set Pinnacle’s 2019 target earnings range such that its projected midpoint was $515 million, compared to Pinnacle’s 2018 actual incentive earnings of $511 million. In both cases, the earnings goals were set to reflect modest sales growth and continued focus on effective cost controls. Actual earnings for APS and Pinnacle West for incentive plan purposes were 9% and 12% below the 2019 target payouts, respectively, as shown on pages 66 and 67. The decrease in 2019 earnings was driven in part by mild weather and lower sales growth, partially offset by effective cost controls. The 2019 operational business unit performance goals were evaluated and revised in certain key business areas to better align with our priorities and emphasize top-quartile or above performance. The average of all business unit metric performance for 2019 was 115% of target compared to 122% of target in 2018 (see page 65 for a table summarizing 2019 through 2018 business unit metric performance). 2019 LONG-TERM INCENTIVE AWARDS Our long-term equity incentive compensation is intended to align the interests of executives and our shareholders and increase the long-term shareholder value while also offering an award opportunity that helps attract and retain qualified, experienced executives. The 2019 long-term incentive grant awarded to Mr. Bement was increased to better align his award amount to competitive market data and Mr. Guldner’s grant was increased in recognition of his expanded responsibilities due to his promotion to 54 Table of Contents EXECUTIVE COMPENSATION Executive Vice President, Public Policy and President of APS. For all other NEOs, we granted the annual awards consistent with our long-term equity incentive compensation determination process as described on page 72. 2017 CEO PERFORMANCE-CONTINGENT AWARD In March 2017, the Committee granted Mr. Brandt a two-year, performance-based cash award (“2017 CEO Performance-Contingent Award”). This award was designed to incent Mr. Brandt, a retirement eligible CEO, to remain in his current role while further emphasizing the Board’s succession planning priorities. The 2017 CEO Performance-Contingent Award was subject to clearly-defined performance goals. The return on equity and earnings conditions were achieved, and consistent with the award agreement, the Corporate Governance Committee assessed Mr. Brandt’s performance with respect to the succession and development actions and concluded that Mr. Brandt had successfully completed those actions, all as detailed further on pages 75-76 of this Proxy Statement. On February 19, 2019, the Committee approved a $4 million payment to Mr. Brandt based on the achievement of the specified performance goals. An amount of $2 million of the 2017 CEO Performance-Contingent Award was included in the Summary Compensation Table for 2018. The remaining $2 million was included in the Summary Compensation Table in the column under “Non-Equity Incentive Plan Compensation” for 2019. In 2019, the Committee committed to making no further retention grants to Mr. Brandt. COMPENSATION GOVERNANCE Our executive compensation program is overseen by the Committee. Through ongoing shareholder engagement and regular assessment of our compensation governance practices, we seek to continue to improve our compensation governance: COMPENSATION GOVERNANCE ●Shareholder feedback informs compensation program design ●Substantial proportion of target compensationis at risk(83% for the former CEO, 77% for the current CEO and 66% for other NEOs) ●Performance shares are 100% tied to relative performance(50% on relative TSR and 50% on relative operational metrics) and require 90th percentile performance for maximum payouts ●No excise tax gross-up provisionsin new or materially amended Change of Control Agreements (defined below) with our prioritiesNEOs ●Anti-hedging policy for all Directors, officers and emphasize top-quartileall employees and anti-pledging policy for all Directors and officers ●Stock ownership guidelinesfor all NEOs (all NEOs are in compliance with the stock ownership guidelines) ●Clawback policyfor our current or above performance.

The 2018 long-term incentive grants awarded to Messrs. Guldner, Hatfield and Schiavoni were increased to better align their award amounts to competitive market data and for Mr. Froetscher, in recognition of his expanded responsibilities due to his promotion to Executive Vice President, Operations of APS. 2017 CEO PERFORMANCE-CONTINGENT AWARD As previously disclosed, in March 2017 the Committee granted the CEO a two-year, performance-based cash award (“2017 CEO Performance-Contingent Award”). This award was designed to incent Mr. Brandt, a retirement eligible CEO, to remain in his current role while further emphasizing the Board’s succession planning priorities. Given the specialized skill sets required of the senior management team in our industry and our Company, a major priority of the CEO is to ensure that the Company’s succession strategy and workforce development pipeline is sufficiently robust and continues to be effective. The Committee believed that this award was critical to retaining a retirement-eligible CEO for what was perceived to be a multiple-year succession planning period. The 2017 CEO Performance-Contingent Award was subject to clearly-defined performance goals. The performance goals were based on a 2017 return on equity percentage, 2017 and 2018 earnings and multiple succession and development actions, all as detailed further on pages 64-66 of this Proxy Statement, and were structured to incentivize continued financial performance while ensuring that succession- and development-related actions were taken. The return on equity and earnings conditions were achieved, and consistent with the award agreement, the Corporate Governance Committee assessed Mr. Brandt’s performance with respect to the succession and development actions and concluded that Mr. Brandt had successfully completed those actions, all as detailed further on pages 64-66 of this Proxy Statement. On February 19, 2019, the Committee approved a $4 million payment to Mr. Brandt based on the achievement of the specified performance goals.

Setting Executive Compensation THE HUMAN RESOURCES COMMITTEE The Committee monitors executive officer compensation throughout the year and undertakes a thorough analysis of our executive officer compensation each fall. This review includes consideration of competitive positions relative to specified labor markets, the mix of compensation components, performance requirements, the portion of pay at risk and tied to performance, and individual performance evaluations. From December through February, the Committee considers and approves executive officer compensation, including salary and cash and non-cash incentives. The Committee makes all compensation decisions relating to our CEO’s compensation, makes awards under the 2012 Plan, and determines the awards under the 2019 Incentive Plans (defined below). The Committee recommends other executive officer compensation decisions, which are approved by the Board for Pinnacle West officers and the Board of Directors of APS for APS officers.

Management conducts evaluations and provides information on the performance of the executive officers for the Committee’s consideration and provides such other information as the Committee may request. Management also assists the Committee in recommending: salary levels; annual incentive plan structure and design, including earnings and business unit performance targets or other goals; long-term incentive plan structure and design, including award levels; and the type, structure, and amount of other awards. The executive officers are available to the Committee’s compensation consultant to provide information as requested by the consultant. At the request of the Chair of the Committee, the CEO or other officers may attend and participate in portions of the Committee’s meetings.

The Committee engaged Frederic W. Cook & Co. to assist the Committee in its evaluation of 2019 compensation for our executive officers (the “Consultant”). The Consultant does not provide any other services to the Company or its affiliates. The Committee has assessed the independence of the Consultant and has concluded that the Consultant is an independent consultant to the Committee as determined under the NYSE rules. 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. 2019 Proxy Statement     49 PAY COMPARISONS In evaluating compensation for the NEOs, the Committee takes into account analysis provided by the Consultant and its recommendations regarding the competitiveness and structure of compensation. 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. CONSULTANT’S REPORT The Consultant reviewed our executive compensation practices and considered the extent to which these practices support our executive compensation objectives and philosophy.

ApplicationThis information reflects Mr. Guldner’ s position as Chairman of the Committee’s JudgmentBoard, President and Chief Executive Officer of PNW and APS. 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 allocate long-term awards between the two forms of equity grants. Determining the Peer Group 58 Table of Contents EXECUTIVE COMPENSATION DETERMINING THE PEER GROUP The Peer Group (defined below) used as one input in our pay comparison process is reviewed annually for its continued appropriateness. The Committee takes into consideration the scope and complexity of the Company’s management responsibility and liability needs, including the following factors: ● Pinnacle West’s operating subsidiary APS operates Palo Verde Generating Station, the largest nuclear power plant in the U.S., which has a $1 billion annual budget, employs one-third of APS employees, and is subject to comprehensive and complex nuclear and environmental regulation; ● The management scope of Palo Verde Generating Station operations necessitates that the Company seeks 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 Palo Verde Generating Station, Four Corners Generating Station and Cholla Power Plant. This is an important factor because APS does not have 100% ownership of these stations and this operational responsibility would not be accounted for in standard measures of Pinnacle West’s or APS’s size. 2019 Proxy Statement     51 Table of Contents Executive Compensation Given these factors, we make certain adjustments to our size measure to account for our operational responsibilities, rather than solely ownership, to allow for more appropriate comparability of Pinnacle West to potential peer companies. In determining the composition of the Peer Group, we adjust our revenues to reflect our control and responsibility for Palo Verde Generating Station, Four Corners Generating Station and Cholla Power Plant. The number usedThis is an important factor because APS does not have 100% ownership of these stations and this operational responsibility would not be 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, rather than solely ownership, to allow for more appropriate comparability of Pinnacle West to potential peer companies. In determining the composition of the Peer Group, we adjust our revenues to reflect our control and responsibility for Palo Verde Generating Station, Four Corners Generating Station and Cholla Power Plant. The number 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 a number of $5.4 billion compared to its reported twelve months ended June 30, 2018 revenues of $3.6 billion. Within the range of potential peers based on adjusted revenues, the Peer Group below is then determined based on additional factors including: ● Scope of management complexity ● Nuclear operations ● Top industry talent (related 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 inmanagement complexity) ● Regulated vs. non-regulated operations ● Complexities of a number of $5.2 billion compared to its reported twelve months ended June 30, 2017 revenues of $3.5 billion. Within the range of potential peers based on adjusted revenues, the Peer Group below is then determined based on additional factors including: ● Scope of management complexitychallenging regulatory environment ● CEO/senior management leadership ● Nuclear operations ● Top industry talent (related to management complexity) ● Regulated vs. non-regulated operations ● Complexities of a challenging regulatory environment ● CEO/senior management leadership As a result of such review, the Committee approved the use of the same peer group that was used in setting 2017 executive compensation with the addition of CMS Energy as a replacement for TECO Energy, Inc. which was acquired by Emera, Inc. As a result of such review, the Committee approved the use of the same peer group that was used in setting 2018 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 close 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). 2020 Proxy Statement 59 Table of Contents EXECUTIVE COMPENSATION As outlined previously, peer proxy data is only one third of the compensation information that is referenced for our NEOs (except for Messrs. Bement and Froetscher, where peer proxy statement data is weighted at 50%). For setting 2019 compensation, information that is referenced for our NEOs (except for Messrs. Bement and Froetscher, where peer proxy statement data is weighted at 50% and 0%, respectively). For 2018, the Peer Group consisted of the following predominantly rate-regulated utilities (the “Peer Group”): Peer Group Alliant Energy Corporation Edison International PPL Corporation Ameren Corporation Eversource Energy SCANA Corporation CMS Energy Hawaiian Electric Industries, Inc. The Southern Company Consolidated Edison, Inc. Industries, Inc. WEC Energy Group, Inc. DTE Energy Company NiSource Inc. WEC Energy Group, Inc. DTE Energy Company OGE Energy Corp. Xcel Energy, Inc. Risk Management and Assessment OGE Energy Corp. RISK MANAGEMENT AND ASSESSMENT The Committee reviewed a compensation risk assessment conducted independently by the Consultant. The assessment focused on the design and application of the Company’s executive compensation programs and whether such programs encourage excessive risk taking by executive officers. In addition, management advised the Committee that management has reviewed the overall compensation programs for the Company’s employees and has concluded that the programs are balanced and do not encourage imprudent risk-taking. Management advised the Committee that non-executive employee compensation programs generally consist of the compensation components contained in the executive compensation programs. Based on the outcome of the Consultant assessment and the information from management, the Committee believes that the Company’s compensation programs (i) do not motivate our executive officers or our non-executive employees to take excessive risks, (ii) are well designed to encourage behaviors aligned with the long-term interests of stockholders, and (iii) are not reasonably likely to have a material adverse effect on the Company. 52      Table of Contents Executive Compensation Executive Compensation Components 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. In setting base salaries, the Committee also considers that base salary is used as the basis for calculating annual incentive awards. 60 Table of Contents EXECUTIVE COMPENSATION In December of 2018, the Committee, based on the considerations set forth above, made the following adjustments to the base salaries of the following NEOs for fiscal year 2019: Name 2018 Base Salary ($) 2019 Base Salary ($) Mr. Brandt(1)       1,395,000       1,440,000 Mr. Guldner(2) 575,000 730,000 Mr. Hatfield 665,000 686,000 Mr. Bement 625,000 645,000 Mr. Froetscher 500,000 540,000 Mr. Smith 550,000 600,000 (1) Mr. Brandt retired on November 15, 2019.

Assessing Performance and Payouts The Board oversees the Company’s business strategy. The Company maintains a rigorous performance goal-setting process wherein goals are set based on our annual business planning process and reviewed for relevance and appropriate alignment with our business strategy. This goal-setting approach is integrated into our performance tracking and business reporting, providing a clear line of sight across the Company on an ongoing basis. The Committee annually reviews the metrics utilized under the annual cash incentive plans to ensure that they remain relevant, with target performance goals set at levels that are intended to be challenging without incentivizing inappropriate risk taking. Individual awards under our annual cash incentive plans are based on the achievement of relevant and objective earnings and business unit goals, which tie payouts directly to core measures of business performance and key operational business unit results and ultimately serve to enhance shareholder value. 2018 ANNUAL INCENTIVE PLAN COMPONENT SUMMARY62 Table of Contents EXECUTIVE COMPENSATION 2019 ANNUAL INCENTIVE PLAN COMPONENT SUMMARY (1) Weightings are shown as a percentage of total incentive opportunity. 54      (2) Includes Mr. Guldner’s participation as President. Table of Contents Executive Compensation2020 Proxy Statement Earnings Component Target Setting In designing the annual cash incentives, the Committee sets earnings levels based on a reasonable range of expectations for the year, while taking into account prior year performance and economic conditions. Due to the regulated nature of the utility industry, earnings growth is impacted by the base rates approved by regulators. Given that the rates we charge customers are generally fixed for several years, our revenue streams don’t increase in a linear year-over-year fashion. As a result, our annual earnings are impacted by our ability to manage costs associated with our operations and investments while our revenues typically remain relatively flat in years following a rate adjustment. Furthermore, planned outages, weather patterns and varying electricity demand can lead to cyclical earnings fluctuations. These factors are considered in our annual business planning and ultimately reflected in the earnings targets that are approved by the Committee. 2018 EARNINGS GOALS For fiscal year 2018, the Committee set threshold, target and maximum Pinnacle West and APS earnings goals that reflected the approval of our 2017 retail rate adjustment and thus represented a meaningful year-over-year increase in the target. We set the APS 2018 earnings target at $512 million for 2018, representing a 6% increase over 2017 actual incentive earnings of $483.8 million. Likewise, we set Pinnacle West’s 2018 target earnings range such that its projected midpoint was $493 million, representing a 4% increase over Pinnacle West’s 2017 actual incentive earnings of $475.4 million. Earnings for APS and Pinnacle West for incentive plan purposes were 5% and 4% above the 2018 targets, respectively as shown on pages 58 and 57.

We set the APS earnings target at $538 million for 2019, relatively flat to 2018 actual incentive earnings of $537.2 million. Likewise, we set Pinnacle West’s 2019 target earnings range such that its projected midpoint was $515 million, compared to Pinnacle West’s 2018 actual incentive earnings of $511 million.

Our use of business unit metrics in our NEOs’ incentive plans promotes our continued success as a safe, sustainable, and overall well-run vertically-integrated and regulated electric utility. Determination Process The determination of business unit metrics and targets is a year-long, multi-step process guided by our strategic priorities. The Board oversees the Company’s business strategy. The Company maintains a rigorous performance goal-setting process wherein goals are set based on our annual business planning process and reviewed for relevance and appropriate alignment with our business strategy. Individual business unit targets are developed using a variety of methods depending on the metric under consideration, including internal trends, external considerations, opportunities to improve performance, and use of industry benchmark data. Targets are intended to incentivize performance while still being attainable. The business unit metrics and targets are then shared and discussed with the Committee and the Board before final metrics and targets are approved by the Committee and the Board. 64 Table of Contents EXECUTIVE COMPENSATION March-April April-June July-November December Corporate Business Priorities ●Each year our executive officers and senior management determine the annual strategic plan and critical areas of focus to align with our ongoing strategy Identify Areas of Focus ●Guided by the annual strategic plan and the critical areas of focus, business units identify business unit-level metrics which tier up to support the broader business priorities for the year Goal-Setting ●Several metrics are set with reference to industry-wide benchmarks where available, and are typically set at the top quartile ●Non-benchmarked metrics are designed to drive favorable trends based on historical internal data Committee and Board Approval of Metrics/ Goals ●The Committee and the Board beforereviews and discusses the metrics and targets provided by the business units ●The Committee and the Board approves final metrics and targets are approved by the Committee and the Board. Under the business unit components of the 2019 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. Performance below the threshold level resulted in a zero payout. Performance above the maximum level resulted in achievement of 200% of target. If performance fell between threshold and target or between target and maximum, linear interpolation was used to determine the actual percentage of target performance achieved. 2019 Business Unit Goals The 2019 Incentive Plans measured NEOs on pre-established business unit performance in up to five key areas: Corporate Resources, Customer Service, Fossil Generation, Palo Verde, and Transmission and Distribution. Within each of these categories are specific metrics designed to incentivize achievements in operational excellence, customer and communities, safety and employee performance, and cost management, ultimately resulting in shareholder value creation. The CEO was evaluated against metrics within each of these five categories to tie the CEO’s incentive to overall operational performance of the Company, and not to emphasize any one unit’s performance over the others. Other NEOs were evaluated based on performance in the business units that correlate to their responsibilities. See “Business Unit Components Under the 2019 Incentive Plans” on page 69 for additional details regarding the metrics, targets and achievement levels for each business unit. We have revised our 2019 metrics in certain key business units to more closely align with our priorities and emphasize top quartile performance and/or improve on historical trends, with year-over-year backtesting conducted to ensure that we are maintaining or increasing the rigor of our goals. The 2019 average of all business unit metrics performance for 2019 was 115% compared to 122% in 2018.

In addition to a target level, some of the performance measures also provided for a threshold level (equal to 50% of target) and a maximum level (equal to 200% of target). Performance above the maximum level resulted in achievement of 200% of target. If performance fell between threshold and target or between target and maximum, linear interpolation was used to determine the actual percentage of target performance achieved. 2018 BUSINESS UNIT GOALS The 2018 Incentive Plans measured NEOs on pre-established business unit performance in up to five key areas: Corporate Resources, Customer Service, Fossil Generation, Palo Verde, and Transmission and Distribution. Within each of these categories are specific metrics designed to incentivize achievements in operational excellence, customer satisfaction, safety and employee performance, and cost management, ultimately resulting in shareholder value creation. The CEO was evaluated against metrics within each of these five categories to tie the CEO’s incentive to overall operational performance of the Company, and not to emphasize any one unit’s performance over the others. Other NEOs were evaluated based on performance in the business units that correlate to their responsibilities.

The component was weighted at 62.5% of the award, with 25% of the award (50% of base salary) earned based on achievement of threshold performance. The CEO Incentive Plan provided that if the threshold earnings number is not met, no incentive payment will be awarded, regardless of business unit performance. Under the terms of the CEO Incentive Plan, earnings calculations are made excluding the impact of rate adjustments related to actions of the ACC within the plan year, and the Committee evaluates the impacts of unusual or non-recurring adjustments on actual earnings and may make adjustments to reflect such impacts. As such, the Committee adjusted the Pinnacle West earnings number to exclude primarily the effect of the timing of an ACC decision related to the installation of the Four Corners selective catalytic reduction equipment deferrals and the refund of excess deferred taxes related to the 2017 Tax Cuts and Job Act. The net effect of these adjustments was a reduction in Pinnacle West earnings from $538.3 to $508.4.

BUSINESS UNIT COMPONENT 2019 Proxy Statement     57As noted above, Mr. Brandt was evaluated against metrics within each of the five business unit areas to tie his incentive to overall operational performance. The business unit component of the CEO Incentive Plan was weighted at 37.5% of the award. Table of Contents Executive Compensation Mr. Brandt’s incentive award was determined exclusively based on the metrics set forth in the CEO Incentive Plan. The Committee did not exercise any discretion to make adjustments to the award based on unanticipated events. APS INCENTIVE PLANS EARNINGS COMPONENT For all NEOs other than the CEO, the earnings portion of the annual cash incentive was weighted at 50% of the award and determined based on APS earnings. The APS Incentive Plan provided 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 provided 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, Palo Verde’s overall business unit performance was required to achieve at least 100% of the target level for 2018 before Mr. Bement could receive any payout under the APS earnings portion. Under the terms of the APS 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. As such, the Committee adjusted the APS earnings number to primarily reflect certain costs that supported public outreach associated with a renewable sources ballot initiative that were incurred primarily to benefit APS and its customers but booked at Pinnacle West (no adjustments were made to the Pinnacle West earning number). The net effect of this adjustment was to reduce APS earnings from $570.3 million to $537.2 million. Performance (in millions) Metric Threshold Target Maximum APS Earnings BUSINESS UNIT COMPONENT As indicated above, NEOs other than the CEO are evaluated based on performance in the business units that correlate to their responsibilities. The business unit component for each NEO other than the CEO was weighted at 50%, with multiple business unit results averaged for applicable NEOs. The APS Incentive Plans allow the Committee to make adjustments for individual performance, and the Committee may exercise discretion under the APS Incentive Plans due to unanticipated events that might arise during the performance period. The Committee did not make any such adjustments for the NEOs in 2018. See “Business Unit Components Under the 2018 Incentive Plans” on page 59 See “Business Unit Components Under the 2019 Incentive Plans” on page 69 for detailed goals and achievement levels for each business unit. 58      2019 CEO Incentive Plan Results The metrics, weightings, and results for Mr. Brandt under the 2019 CEO Incentive Plan are outlined below: 37.5% Business Unit Performance NEO       62.5% PNW Earnings (%)       Corporate Resources (%)       Customer Service (%)       Fossil Generation (%)       Palo Verde (%)       Transmission/ Distribution (%)       2019 Total (%) Mr. Brandt 88(1) 121(2) 63 131 161 100 115 Weighting (62.5) (7.5) (7.5) (7.5) (7.5) (7.5) (37.5) (1) TableAs a percentage of Contents Executive Compensation 2018 APS INCENTIVE PLAN RESULTS The metrics, weightings,midpoint; and results for Messrs.

Since Mr. Brandt retired during 2019, he received a prorated amount of the incentive award based on the amount of time Mr. Brandt was employed during 2019. The Committee did not exercise any discretion to make adjustments to the award other than the reduction to Pinnacle West earnings as noted above. APS Incentive Plans EARNINGS COMPONENT For all NEOs other than the former and current CEO, the earnings portion of the annual cash incentive was weighted at 50% of the award and determined based on APS earnings. The APS Incentive Plan provided that if the threshold earnings number is not met, no incentive payment will be awarded, regardless of business unit performance. From January 1, 2019 until November 15, 2019, Mr. Guldner participated in the APS Incentive Plan as President of APS and Executive Vice President Public Policy of Pinnacle West and the earnings portion of his annual cash incentive was weighted at 50% of the award and determined based on APS earnings. From November 15, 2019 until December 31, 2019, Mr. Guldner, as Chairman of the Board, President and Chief Executive Officer of PNW and APS, continued to participate in the APS Incentive Plan but the award opportunities were based 50% on the achievement of specified 2019 Pinnacle West earnings levels. The Palo Verde Incentive Plan provided 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, Palo Verde’s overall business unit performance was required to achieve at least 100% of the target level for 2019 before Mr. Bement could receive any payout under the APS earnings portion. Under the terms of the APS 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. As such, the Committee adjusted the APS earnings number to exclude primarily the effect of the timing of an ACC decision related to the installation of the Four Corners selective catalytic reduction equipment deferrals and the refund of excess deferred taxes related to the 2017 Tax Cuts and Job Act. The net effect of these adjustments was a reduction in APS earnings from $565.3 to $533.1. Performance (in millions) Metric Threshold Target Maximum APS Earnings(1) (1) From November 15, 2019 until December 31, 2019, Mr. Guldner’s award opportunities were based 50% on the achievement of a particular measurethe 2019 PNW earnings levels specified in the CEO Incentive Plan.

The business unit component for each NEO other than the former CEO was weighted at 50%, with multiple business unit results averaged for applicable NEOs. The APS Incentive Plans allow the Committee to make adjustments for individual performance, and the Committee may exercise discretion under the APS Incentive Plans due to unanticipated events that might arise during the performance period. The Committee did not make any such adjustments for the NEOs in 2019.

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 our Executive Vice Presidents, our annual long-term equity awards were granted 70% to performance-based measures and 30% to time-based vesting and for all other officers, 60% to performance-based measures and 40% to time-based vesting. 2019 LONG-TERM EQUITY INCENTIVE COMPONENT SUMMARY Vehicle % of Target Equity Pay Mix Measurement Period Performance Link Performance Shares 70 3 years Relative TSR (50%) Relative Operational Performance (50%) RSUs 30 Vest ratably over 4 years Stock Price To determine the amount of performance share and RSU awards for the annual grants made in February of each year, the Committee first establishes a target compensation value for each officer that it wants to deliver through long-term equity award opportunities. The Committee considers 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 considers target value in light of the Company’s achievement of earnings targets and overall performance. Once the target value is established, the Committee determines 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 2019 awards 70% to performance shares and 30% to RSUs for the CEO and Executive Vice Presidents and 60% to performance shares and 40% to RSUs for all other officers.

We believe using TSR strengthens the link between officer performance and shareholder return. We anticipate that the common stock payout, if any, related to this element will be made in February 2022. Starting with the 2020 grants for our CEO and Executive Vice Presidents, the portion of the performance shares that are TSR based will vest at target only if the Company’s three-year relative TSR performance equals or exceeds the 55th percentile of the Index. This represents a change from the Company’s past awards, which vested at the median of the Index.

OPERATIONAL PERFORMANCE The Company’s “average performance” with respect to the metrics listed below will be the average of the Company’s percentile ranking for each of these metrics during each of the three years of the performance period: ● The Company’s percentile ranking for each of these metrics during each of the three years of the performance period: ● The Company’s percentile ranking based on customer reliability results relative to other companies reported in the Edison Electric Institute (“EEI”) data; ● The Company’s ranking for a customer-to-employee improvement ratio, based on data provided by S&P Global Market Intelligence (“Market Intelligence”), an independent third-party data system, relative to other companies reported in the Market Intelligence data; ● The Company’s ranking for a customer-to-employee improvement ratio, based on data provided by SNL Financial (“SNL”), an independent third-party data system, relative to other companies reported in the SNL data; 2020 Proxy Statement 73 Table of Contents EXECUTIVE COMPENSATION ● The Company’s percentile ranking based on the OSHA rate (All Incident Injury Rate) relative to other companies reported in the EEI data; ● The Company’s percentile ranking based on nuclear capacity factor relative to other companies reported in the SNL data; and ● The Company’s percentile ranking based on coal capacity factor relative to other companies reported in the SNL data. The metrics selected are direct indicators of key business performance success. The metrics can be readily benchmarked and provide a clear barometer of top-tier performance excellence. We believe a focus on these performance metrics over a three-year period aligns long-term compensation with key operational goals, thereby enhancing overall Company performance. We anticipate that the common stock payout, if any, related to this performance element will be made in October 2021. The recipient must remain employed with the Company throughout the performance period, unless the recipient meets any of the exceptions described under “Potential Payments upon Termination or Change of Control.” A recipient of performance shares will receive additional shares of common stock equal to the amount of dividends that the recipient would have received had the recipient directly owned the shares from the date of grant to the date of payment, plus interest on such dividends at the rate of 5% per annum, compounded quarterly, divided by the fair market value of one share of stock on the date ofOSHA rate (All Incident Injury Rate) relative to other companies reported in the stock payout.

For the three-year period ended December 31, 2017, our TSR percentile was 63.1% compared to the Index. For the same period, our average performance percentile with respect to the 2015 performance metrics was 68.6% Payouts of 2016 Plan Awards In 2016, the Committee granted performance shares to the NEOs (with the exception of Mr. Smith who was not an employee at the time of the grant), based on relative TSR and relative operational performance. For the three-year period ended December 31, 2018, our TSR percentile was 64.7% compared to the companies in the Index. For the same period, our average performance percentile with respect to the 2016 performance metrics was 62.5% compared to the companies included in the operational performance metrics. The actual payout to each NEO is identified in the Option Exercises and Stock Vested table. RSUs We granted RSUs to our NEOs in February 2018. 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. The 2018 RSUs are payable at the election of the participant made shortly after the date of the initial grant, either 100% in stock, 50% in cash and 50% in stock, or 100% in cash, and will vest each February 20 in an amount equal to the number of RSUs vesting on such date multiplied by the closing price of a share of our common stock on that date. The RSUs accrue dividend rights on the vested RSUs, equal to the amount of dividends that the participant would have received had the participant directly owned stock equal to the number of vested RSUs from the date of grant to the date of payment, plus interest at the rate of 5% per annum, compounded quarterly, with such amount paid either 100% in stock, 50% in cash and 50% in stock, or 100% in cash based on the participant’s election as discussed above.

SUPPLEMENTAL AWARD 2017 CEO Performance-Contingent Award In March 2017, the Committee granted Mr. Brandt a two-year, performance-based cash award. This award was designed to incent Mr. Brandt, a retirement-eligible CEO, to remain in his current role while further emphasizing the Board’s succession planning priorities. Given the specialized skill sets required of the senior management team in our industry and our Company, a major priority of the CEO is to ensure that the Company’s existing succession strategy and workforce development pipeline is sufficiently robust and continues to be effective. The Committee believed that this award was critical to retaining a retirement-eligible CEO for what was perceived to be a multiple-year succession planning period. The award was comprised of two tranches that were performance-conditioned on specific return on equity, earnings, and succession planning goals, with a maximum potential payout to Mr. Brandt of $4 million: STRUCTURE AND PERFORMANCE CRITERIA OF 2017 CEO PERFORMANCE-CONTINGENT AWARD In March 2017, the Committee granted the CEO a two-year, performance-based cash award.

Mr. Brandt was required to deliver to the Corporate Governance Committee at each of its meetings between June 2017 and February 2018 progress reports on the Year 1 Milestones. The Corporate Governance Committee evaluated Mr. Brandt’s performance and determined that the Year 1 Milestones were met based on that (i) Mr. Brandt identified the succession candidates for the senior officer positions listed in the 2017 CEO Performance-Contingent Award, or if there was not a suitable internal candidate, Mr. Brandt presented a plan for an external search for such candidate, (ii) Mr. Brandt delivered the written succession/development plans for the senior officers specified in the 2017 CEO Performance-Contingent Award, (iii) Mr. Brandt delivered the assessments of the senior officer candidates and the performance development of a specific senior officer listed in the 2017 CEO Performance-Contingent Award, (iv) Mr. Brandt delivered the progress reports required by the 2017 CEO Performance-Contingent Award, and (v) there were no gaps in the identification of successor candidates, reports submitted were complete and thorough and that the Company had devoted sufficient resources to the execution and development of the succession plans.

Mr. Brandt was paid the $4 million 2017 CEO Performance-Contingent Award on February 28, 2019. An amount of $2 million of the 2017 CEO Performance-Contingent Award is included in the Summary Compensation Table in the column under “Non-Equity Incentive Plan Compensation” for 2019. The other $2 million of the 2017 CEO Performance-Contingent Award was included in the Summary Compensation Table for 2018 because, although no amount was paid to Mr. Brandt in 2018, in February of 2018 when the Committee determined that the (i) minimum ROE condition, (ii) 2017 earnings threshold and (iii) Year 1 Milestones each had been met, Mr. Brandt would have been owed $2 million if he had retired from the Company in 2018. In 2019, the Committee committed to making no further retention grants to Mr. Brandt. BENEFITS PENSION PROGRAMS The NEOs participate in the Pinnacle West Capital Corporation Retirement Plan (the “Retirement Plan”) and the Supplemental Excess Benefit Retirement Plan (the “Supplemental Plan”). We describe these plans in more detail under “Discussion of Pension Benefits”. The Company believes that the pension programs are important recruitment and retention tools. DEFERRED COMPENSATION PROGRAM The Company offers to its executive officers the ability, if the officer so chooses, to participate in a deferred compensation program. We describe our deferred compensation program in more detail under “Discussion of Nonqualified Deferred Compensation”. We offer our deferred compensation program because the Committee believes that it is standard market practice to permit officers to defer some portion of their cash compensation. However, we generally consider the value in the deferred compensation plan to be the participant’s own money and do not give this amount significant weight in making compensation decisions. A discretionary credit award under the deferred compensation plan for Mr. Bement is discussed under the heading “Discussion of Nonqualified Deferred Compensation”. 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.” We believe that the possibility of strategic transactions or unsolicited offers creates job uncertainty for executives, and that the Change of Control Agreements are effective tools to provide incentives for executives to stay with the Executive Compensation76 Table of Contents EXECUTIVE COMPENSATION Based on the successful achievement of the performance criteria, the Committee approved awarding the full $4 million performance-based cash award.

In addition, we believe that if the agreements are appropriately structured, they do not deter takeovers or disadvantage shareholders. Each agreement is terminable 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 and 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. In addition to the Change of Control Agreements described above, under the terms of our 2012 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, 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. PERQUISITES We have had a long-standing practice of providing only limited perquisites to our executive officers.

Other Considerations STOCK OWNERSHIP AND RETENTION GUIDELINES Stock Ownership and Retention Guidelines We believe that linking a significant portion of an officer’s current and potential future net worth to the Company’s success, as reflected in our stock price, helps to ensure that officers have a stake similar to that of our shareholders. Stock ownership guidelines also encourage the long-term management of the Company for the benefit of the shareholders. The Company’s Guidelines are based on the officer’s position and his or her base salary. The ownership requirements are shown below in respect of the indicated officer position: Officer Multiple of an officer’s current and potential future net worth to the Company’s success, as reflected in our stock price, helps to ensure that officers have a stake similar to that of our shareholders. Stock ownership guidelines also encourage the long-term management of the Company for the benefit of the shareholders. The Company’s Guidelines are based on the officer’s position and his or her base salary. The ownership requirements are shown below in respect of the indicated officer position: OfficerBase Salary(1) Multiple of Base Salary(1) Chief Executive Officer 5 times Base Salary APS President and all Executive and Senior Vice Presidents 2 times Base Salary All other Vice Presidents and Officers 1 times Base Salary (1) Each officer is expected to meet his or her ownership requirement within five years following such officer’s election (the “Phase-in Period”). In the event of (1) a promotion or a change in the Guidelines that would cause the officer to move into a higher multiple level or (2) a base salary increase of more than 20% over the officer’s previous base salary, an officer will have an additional three-years to meet his or her applicable ownership requirement. If the officer does not attain compliance with his or her ownership requirement by the end of the Phase-in Period, any subsequent grants of equity compensation to such officer will be payable solely in shares of stock until the ownership requirement is met. Under the Guidelines, the CEO may grant exceptions for hardship and other special circumstances. The types of ownership arrangements counted toward the Guidelines are: common stock, whether held individually, jointly, or in trust with or for the benefit of an immediate family member; shares issued upon the vesting of RSUs or the payout of performance shares; and unvested RSUs to the extent they will result in the issuance of common stock to the officer. Officers may not sell or otherwise transfer (“Dispose”) any shares of Company stock received by them pursuant to any of the Company’s compensation or benefit programs (net of shares sold or surrendered to meet tax withholding or exercise requirements) until his or her ownership requirement has beenwithin five years following such officer’s election (the “Phase-in Period”). In the event of (1) a promotion or a change in the Guidelines that would cause the officer to move into a higher multiple level or (2) a base salary increase of more than 20% over the officer’s previous base salary, an officer will have an additional three-years to meet his or her applicable ownership requirement. If the officer does not attain compliance with his or her ownership requirement by the end of the Phase-in Period, any subsequent grants of equity compensation to such officer will be payable solely in shares of stock until the ownership requirement is met.

In addition, Directors and officers may not pledge, margin or otherwise grant an economic interest in any shares of Company stock. CLAWBACK POLICY Pinnacle West has a clawback policy that applies to specified current or former executive officers, including our NEOs. Under the policy, in the event of any material restatement of the consolidated financial statements of the Company and its subsidiaries within three years of the first public release or filing with the SEC, the Committee may, within 12 months after the material restatement, require forfeiture and/or return to the Company of all or a portion of the compensation vested, awarded or received under any bonus award, short-term incentive award, equity award (including any award of restricted stock, performance shares, phantom stock, deferred stock units or RSUs) or other award during the period subject to restatement and the 12-month period following the first public issuance or filing with the SEC of the financial statements that were restated, by any executive that the Committee determines has personally engaged in intentional misconduct that caused or partially caused the need for such restatement. Any forfeiture and/or return of compensation by an executive under the policy will be limited to the portion that the executive would not have received if the consolidated financial statements had been reported properly at the time of first public release or filing with the SEC. By accepting any award as to which this policy applies, each executive agrees to forfeit and/or return compensation to the Company as provided by the policy. The policy does not limit the ability of the Company to pursue forfeiture or reclaim payments under other legal rights. TAXATION CONSIDERATIONS REGARDING EXECUTIVE COMPENSATION Pursuant to Section 162(m) of the Internal Revenue Code (the “Code”), for federal income tax purposes, publicly-traded corporations generally are not permitted to deduct annual compensation in excess of $1 million paid to any of certain top executives. The Committee and the Board may weigh the tax consequences of the total compensation program when setting the total compensation package for an officer. However, the Committee and the Board do not routinely apply the tax-deductibility rules to limit what they determine otherwise to be necessary and appropriate compensation awards or as a justification for awarding compensation below $1 million. As a result of changes made by the 2017 Tax Cuts and Jobs Act, certain “performance-based” compensation, which was excludible from the scope of Section 162(m) under prior law, must now be included in determining the $1 million limitation unless it qualifies under a transition rule applicable to certain compensation arrangements in place as of November 2, 2017. In December 2019, the Internal Revenue Service released proposed regulations which provide additional guidance related to the transition rule. Based on these proposed regulations, the Company continues to believe that performance-based awards granted to our executive officers, and in place as of November 2, 2017, will be deductible under this transition rule. However, until the regulations are final, no assurance can be given that compensation intended to satisfy the requirements for this transition rule will in fact be deductible when paid. Further, the Committee reserves the right to modify compensation that was initially intended to be exempt from Section 162(m) if it determines that such modifications are consistent with the Company’s business needs. 78 Table of Contents EXECUTIVE COMPENSATION NEO Pay Summaries The charts below illustrate the strong emphasis that we place on performance-based, shareholder-aligned incentive compensation: Donald E.

This restriction extends to the purchase or creation of any short sales, zero-cost collars, forward sales contracts, puts, calls, options or other derivative securities in respect of any shares of Company stock. Clawback Policy Pinnacle West has a clawback policy that applies to specified current or former executive officers, including our NEOs. Under the policy, in the event of any material restatement of the consolidated financial statements of the Company and its subsidiaries within three years of the first public release or filing with the SEC, the Committee may, within 12 months after the material restatement, require forfeiture and/or return to the Company of all or a portion of the compensation vested, awarded or received under any bonus award, short-term incentive award, equity award (including any award of restricted stock, performance shares, phantom stock, deferred stock units or RSUs) or other award during the period subject to restatement and the 12-month period following the first public issuance or filing with the SEC of the financial statements that were restated, by any executive that the Committee determines has personally engaged in intentional misconduct that caused or partially caused the need for such restatement. Any forfeiture and/or return of compensation by an executive under the policy will be limited to the portion that the executive would not have received if the consolidated financial statements had been reported properly at the time of first public release or filing with the SEC. By accepting any award as to which this policy applies, each executive agrees to forfeit and/or return compensation to the Company as provided by the policy. The policy does not limit the ability of the Company to pursue forfeiture or reclaim payments under other legal rights. Taxation Considerations Regarding Executive Compensation Pursuant to Section 162(m) of the Internal Revenue Code (the “Code”), for federal income tax purposes, publicly-traded corporations generally are not permitted to deduct annual compensation in excess of $1 million paid to any of certain top executives. The Committee and the Board may weigh the tax consequences of the total compensation program when setting the total compensation package for an officer. However, the Committee and the Board do not routinely apply the tax-deductibility rules to limit what they determine otherwise to be necessary and appropriate compensation awards or as a justification for awarding compensation below $1 million.

In August 2018, the Internal Revenue Service released initial guidance related to the transition rule. Based on this initial guidance, the Company continues to believe that performance-based awards granted to our executive officers, and in place as of November 2, 2017, will continue to be deductible under this transition rule. However, the Internal Revenue Service indicated further guidance would be forthcoming. As such, no assurance can be given that compensation intended to satisfy the requirements for this transition rule will in fact be deductible. Further, the Committee reserves the right to modify compensation that was initially intended to be exempt from Section 162(m) if it determines that such modifications are consistent with the Company’s business needs. 68      Table of Contents Executive Compensation Summary Compensation Table The following table provides information concerning the total compensation earned or paid to the Company’s NEOs: Name and Principal Position Year Salary ($)(1) Bonus ($)(2) Stock Awards ($)(3) Non-Equity Incentive Plan Compensation ($)(4) Change in Pension Value and Nonqualified Deferred Compensation Earnings ($)(5) All Other Compensation ($)(6) Total ($) Donald E.

The actual awards paid to the NEOs under the 2018 Incentive Plans are disclosed in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table. With respect to Messrs. Hatfield, Froetscher, Guldner and Schiavoni, (2) As required by SEC rules, the “Estimated Possible Payouts” represent the “threshold,” “target,” and “maximum” payouts the NEOs were eligible to receive under the 2019 Incentive Plans. The actual awards paid to the NEOs under the 2019 Incentive Plans are disclosed in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table. With respect to Messrs. Guldner, Hatfield, Froetscher and Smith, 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. Bement 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. The CEO Incentive Plan does not specify a target opportunity. We calculated a representative target amount for Mr. Brandt by using the final results of the earnings and business unit components from 2017 (each of which were factors in Mr. Brandt’s 2017 incentive award) to compute a hypothetical payout under the current 2018 CEO Incentive Plan. That hypothetical payout is used as a representative target amount. See “Executive Compensation Components — Annual Cash Incentives” in the CD&A for additional information about the 2018 (each of which were factors in Mr. Brandt’s 2019 incentive award) to compute a hypothetical payout under the current 2019 CEO Incentive Plan. That hypothetical payout is used as a representative target amount. See “Executive Compensation Components — Annual Cash Incentives” in the CD&A for additional information about the 2019 Incentive Plans.

There were no forfeitures in 2019. (5) This amount represents the 2019 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 ($90.65). There were no forfeitures in 2019. (6) From January 1, 2019 until November 15, 2019, Mr. Guldner participated in the APS Incentive Plan as President of APS and Executive Vice President Public Policy of Pinnacle West and he had a target award opportunity of up to 90% of his base salary. From November 15, 2019 until December 31, 2019, Mr. Guldner, as Chairman of the Board, President and Chief Executive Officer of PNW and APS, continued to participate in the APS Incentive Plan but he had a target award opportunity of up to 110% of his base salary. The amounts in these columns represent the incentive amounts that Mr. Guldner could have received if he had been in each respective position with the Company and APS for the entire year. However, Mr. Guldner was only eligible to receive a prorated amount under the APS Incentive Plan based on the amount of time he held each position.

On November 4, 2019, the Committee approved a Consulting Services Agreement with Mr. Brandt that was effective upon his retirement date of November 15, 2019 (the “Consulting Services Agreement”). For a period of 12 months (“Retention Period”), Mr. Brandt will consult and advise on matters as requested by the Board in the transition of the responsibilities of the Chief Executive Officer to Mr. Guldner. In particular, Mr. Brandt will provide advice and support regarding the transition of oversight of the Palo Verde Generating Station. Mr. Brandt may receive a total consulting fee of up to $1.75 million that will be payable as $25,000 per month for the first 11 months (the “Monthly Fee”) and the balance of the consulting fee (the “Final Fee”) will be paid at the end of the Retention Period, subject to an evaluation by the Committee and the Corporate Governance Committee that Mr. Brandt has performed the duties in the Consulting Services Agreement. Mr. Brandt is subject to certain restrictions and covenants in the Consulting Services Agreement, including confidentiality, non-compete and non-solicitation provisions. The Consulting Services Agreement also includes termination provisions as described herein under “Potential Payments upon Termination or Change of Control.” Pinnacle West and Mr. Smith executed an offer letter dated July 19, 2018.

(8) This amount represents: (i) the performance shares issued in 2017 — the SEC rules require us to assume a number of shares equal to the target (100% of the Base Grant) payout level of these performance shares, although the actual number of shares awarded, if any, will not be determined until after the end of the performance period, which ends on December 31, 2019; and (ii) accrued dividend rights (and interest thereon) that will be paid in stock to the extent the underlying performance shares actually vest and are paid out, as follows: Mr. Brandt — 1,954; Mr. Hatfield — 400; Mr. Bement — 266; Mr. Froetscher— 156; Mr. Guldner— 222; and Mr. Schiavoni — 488. (9) This amount represents the performance shares issued in 2016. The performance period for these performance shares ended December 31, 2018; however, the payout was not determined until February 2019 for the portion tied to TSR and the payout, if any, for the portion tied to the six operational performance metrics will not be determined until October 2019, which is when the Company anticipates that we will have the information necessary to determine whether, and to what extent, the six performance metrics were met. SEC rules require us to (i) assume a number of shares equal to the maximum (200% of Base Grant) payout level for the 2016 performance shares; and (ii) accrued dividend rights (and interest thereon) that will be paid in stock to the extent the underlying performance shares actually vest and are paid out, as follows: Mr. Brandt — 7,271; Mr. Hatfield — 1,405; Mr. Bement — 661; Mr. Froetscher — 579; Mr. Guldner — 661 and Mr. Schiavoni — 1,818.

Discussion of Pension Benefits Retirement Plan and Supplemental Plan RETIREMENT PLAN AND SUPPLEMENTAL PLAN The Company’s Retirement Plan is a tax-qualified, noncontributory retirement plan for salaried and hourly employees. The Supplemental Plan provides additional retirement benefits for key salaried employees but does not duplicate benefits provided under the Retirement Plan. The total benefit is calculated and then benefits payable under the Retirement Plan are paid from a tax-exempt trust and any remaining benefits due under the Supplemental Plan are paid from the general assets of the Company. 88 Table of Contents EXECUTIVE COMPENSATION 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”). 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 are paid from a tax-exempt trust and any remaining benefits due under the Supplemental Plan are paid from the general assets of the Company.Plan. 76      Table of Contents Executive Compensation 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”). 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). Messrs. Brandt, Hatfield, Bement and Froetscher currently qualify for early retirement, but not normal retirement, under the Retirement Plan and the Supplemental Plan. Mr. Schiavoni qualified for early retirement under the Retirement Plan and the Supplemental Plan when he retired. Mr. Guldner does not currently qualify for early or normal retirement under either the Retirement Plan or the Supplemental Plan. Effective April 1, 2003, the Company changed the benefit accrual formula for both the Retirement Plan and the Supplemental Plan to a retirement account balance formula (the “Account Balance Formula”). Active participants were able to elect to either (1) continue to earn benefits calculated under the Traditional Formula, or (2) earn benefits calculated (a) under the Traditional Formula for service through March 31, 2003, and (b) under the Account Balance Formula for service after that date. Messrs. Brandt’s and Froetscher’s benefits are calculated under the combined Traditional Formula/Account Balance Formula. Messrs. Hatfield’s, Bement’s, Guldner’s and Schiavoni’s 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). Messrs. Hatfield, Bement and Froetscher currently qualify for early retirement, but not normal retirement, under the Retirement Plan and the Supplemental Plan. Mr. Brandt qualified for early retirement under the Retirement Plan and the Supplemental Plan when he retired. Messrs. Guldner and Smith do not currently qualify for early or normal retirement under either the Retirement Plan or the Supplemental Plan. Effective April 1, 2003, the Company changed the benefit accrual formula for both the Retirement Plan and the Supplemental Plan to a retirement account balance formula (the “Account Balance Formula”). Active participants were able to elect to either (1) continue to earn benefits calculated under the Traditional Formula, or (2) earn benefits calculated (a) under the Traditional Formula for service through March 31, 2003, and (b) under the Account Balance Formula for service after that date. Messrs. Brandt’s and Froetscher’s benefits are calculated under the combined Traditional Formula/Account Balance Formula. Messrs. Guldner’s, Hatfield’s, Bement’s, and Smith’s benefits are calculated under the Account Balance Formula. Under the Account Balance Formula, a notional account is established for each eligible participant and benefits are generally payable at termination of employment. The Company credits monthly amounts (based on the participant’s current monthly compensation) to a participant’s account. Under the Retirement Plan, Company credits are based on the following formula: Age Plus Whole Years of Service at End of Plan Year Percent of Monthly Compensation Contribution Rate (%) 2020 Proxy Statement 89 Less than 40 4 40-49 5 50-59 6 60-69 7 70-79 9 80 and over 11 2019 Proxy Statement     77 Table of Contents EXECUTIVE COMPENSATION Under the Retirement Plan, Company credits are based on the following formula: Age Plus Whole Years of Service at End of Plan Year Percent of Monthly Compensation Contribution Rate (%) Less than 40 4 40-49 5 50-59 6 60-69 7 70-79 9 80 and over 11 In addition, participants in the Retirement Plan on December 31, 2002 were eligible for up to 10 years of transition credits based on age and years of service (with the maximum transition credit equal to 2.75% of current monthly compensation). Under the Supplemental Plan, Company credits are based on the following formula: TableAge at End of ContentsPlan Year Executive Percent of Monthly Compensation Contribution Rate (%) In addition, participants in the Retirement Plan on December 31, 2002 were eligible for up to 10 years of transition credits based on age Less than 35 12 35-39 14 40-44 16 45-49 20 50-54 24 55 and years of service (with the maximum transition credit equal to 2.75% of current monthly compensation).

For purposes of calculating the Traditional Formula Benefit and the Account Balance Formula benefit under the Retirement Plan, compensation consists solely of base salary up to $275,000, including any employee contributions under the Company’s 401(k) plan, flexible benefits plan and qualified transportation arrangement under Section 132(f) of the Code. Amounts voluntarily deferred under other deferred compensation plans, bonuses, incentive pay and long-term equity awards are not taken into account under the Retirement Plan. The Supplemental Plan takes these amounts into account (with certain exceptions) plus base salary beyond the $275,000 Company credits under the Supplemental Plan stop at the end of the year in which a participant attains 25 years of service (the “25-Year Cap”). For purposes of calculating the Traditional Formula Benefit and the Account Balance Formula benefit under the Retirement Plan, compensation consists solely of base salary up to $280,000, including any employee contributions under the Company’s 401(k) plan, flexible benefits plan and qualified transportation arrangement under Section 132(f) of the Code. Amounts voluntarily deferred under other deferred compensation plans, bonuses, incentive pay and long-term equity awards are not taken into account under the Retirement Plan. The Supplemental Plan takes these amounts into account (with certain exceptions) plus base salary beyond the $280,000 limit. Participants typically begin accruing service when hired and are vested after completing three years of service. Under both the Retirement Plan and the Supplemental Plan, Traditional Formula Benefits are usually paid in the form of a level annuity with or without survivorship and generally are not available as a lump sum. Account Balance Formula benefits are eligible to be paid in the form of a level annuity with or without survivorship or as a lump sum. All optional benefit forms available through the Retirement Plan are approximately actuarially equivalent. Under the Supplemental Plan, the 50% joint and survivor benefit is fully subsidized, and the other benefit forms are partially subsidized. The Supplemental Plan offers an additional five-year certain payment option (payable in 60 monthly installments). 90 Table of Contents EXECUTIVE COMPENSATION Effective January 1, 2011, the Supplemental Plan was amended to reduce the Company credits for individuals who became participants on or after January 1, 2011 to the levels listed in the following table: Age at End of Plan Year      Percent of Monthly Compensation Contribution Rate (%) Less than 35 8 35-39 9 40-44 10 45-49 12 50-54 15 55 and over 18 Individuals who became participants in the Supplemental Plan on or after January 1, 2011 are not entitled to receive a fully subsidized 50% joint and survivor annuity form of benefit, and the 25-Year Cap has been eliminated.

Discussion of Nonqualified Deferred Compensation DCP AND 2005 PLAN DCP AND 2005 PLAN Effective January 1, 1992, the Company established The Pinnacle West Capital Corporation, Arizona Public Service Company, SunCor Development Company, and El Dorado Investment Company Deferred Compensation Plan (the “DCP”). Under the DCP, a participant who is an employee is allowed to defer up to 50% of annual base salary and up to 100% of year-end bonus, which would include awards under regular annual incentive plans, but not special incentive payments. A participant who is a member of the Board is allowed to defer up to 100% of the annual cash fees payable to the participant. Amounts deferred by participants are credited with interest at various rates in substantially the same manner as interest is credited pursuant to the 2005 Plan, as described below. Distributions may be made (1) within 60 days after the fifth year an amount was deferred, (2) on account of an unforeseen emergency, (3) on account of retirement after attaining age 65 with five years of service or after attaining age 55 with 10 years of service (“Retirement Benefit”), (4) on account of termination prior to retirement (“Termination Benefit”), (5) on account of disability, or (6) on account of death before termination of employment. The Retirement Benefit and Termination Benefit are payable in a lump sum or in 5, 10, or 15 equal annual installments, as elected by the participant. Other benefits are generally paid in a lump sum. The method of crediting interest on lump sum and installment payments under the DCP is substantially the same as the method used in the 2005 Plan, as described below. 92 Table of Contents EXECUTIVE COMPENSATION On December 15, 2004, the Board authorized the adoption of a new nonqualified deferred compensation plan for post-2004 deferrals (the “2005 Plan”). No future deferrals will be permitted under the DCP. The 2005 Plan, effective as of January 1, 2005, is based in large part on the DCP as described above. The 2005 Plan was adopted to comply with the requirements of Section 409A of the Code. Under the 2005 Plan, a participant who is an employee is allowed to defer up to 50% of the participant’s base salary and up to 100% of the participant’s bonus, including regular awards under annual incentive plans, but not special awards. A participant who is a member of the Board is allowed to defer up to 100% of the annual cash fees payable to the participant. Amounts deferred by participants are credited with interest at various rates, as described below. Deferral elections of base salary and director’s fees must be made prior to the calendar year in which such base salary or director’s fees will be paid. A deferral election with respect to a bonus must be made before the first day of the calendar year in which the bonus is earned. When making a deferral election, a participant also makes an election regarding the time and form of the participant’s distributions from the 2005 Plan. Distributions from the 2005 Plan must be made in accordance with Section 409A of the Code. Distributions may be made (1) in January of the fifth year following the year in which an amount was deferred, (2) on account of an unforeseeable financial emergency, (3) either (i) termination of employment or (ii) the later of termination of employment or attainment of age 55, or (4) on account of death before termination of employment. In the event of termination of employment, attainment of age 55 or death, the benefit is payable in a lump sum or in 5, 10 or 15 equal annual installments, as elected by the participant. Benefits in the other circumstances are generally paid in a lump sum. 80      Table of Contents Executive Compensation The 2005 Plan provides for a single rate of interest that will be determined by the plan committee, but which rate shall in no event be less than the rate of interest equal to the 10-year U.S. Treasury Note rate as published on the last business day of the first week of October preceding a plan year. The plan committee set the rate at 7.5% for plan year 2018. The 2005 Plan provides for a single rate of interest that will be determined by the plan committee, but which rate shall in no event be less than the rate of interest equal to the 10-year U.S. Treasury Note rate as published on the last business day of the first week of October preceding a plan year. The plan committee set the rate at 7.5% for plan year 2019. Effective January 1, 2009, the Company amended the 2005 Plan to permit the Company, in its discretion, to award discretionary credits to participants. Discretionary credits generally will be paid at the time and in the form provided in the written award agreement. The Company made a discretionary credit award to Mr. Bement in 2008 pursuant to the 2005 Plan consisting of $350,000 as of December 17, 2008, $70,000 as of January 1, 2010 and an additional $70,000 on January 1 of each of the next four years thereafter (the “2008 Bement DCP Discretionary Credits”). The 2008 Bement DCP Discretionary Credits earn interest in accordance with the 2005 Plan. The 2008 Bement DCP Discretionary Credits vested on December 31, 2014 and will be payable to Mr. Bement following his termination from the Company in such form as elected by Mr. Bement. Additionally, the Company made a discretionary credit award to Mr. Bement in 2014 pursuant to the 2005 Plan consisting of $75,000 as of January 1, 2015 and an additional $75,000 on January 1 of each of the next three years thereafter (the “2014 Bement DCP Discretionary Credits” and together with the 2008 Bement DCP Discretionary Credits, the “Bement DCP Discretionary Credits”). The 2014 Bement DCP Discretionary Credits earn interest in accordance with the 2005 Plan. The 2014 Bement DCP Discretionary Credits vested on December 31, 2018 and will be payable to Mr. Bement following his termination from the Company in such form as elected by Mr. Bement. Participation in both the DCP and the 2005 Plan is limited to officers, the Company’s senior management group and directors of the Company and participating affiliates. The Company’s obligations under the DCP and the 2005 Plan are unfunded (except in the limited change of control circumstance discussed below) and unsecured. 2020 Proxy Statement 93 Table of Contents EXECUTIVE COMPENSATION 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. Unless we note otherwise, the discussion below assumes that any Termination Event took place on December 31, 2019 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, the 2005 Plan and pension benefits. Amounts payable to Messrs. Brandt, Guldner, Hatfield, Bement, Froetscher, and Smith under the DCP and the 2005 Plan 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. 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 (excluding Mr. Brandt who retired in November 2019) had died on December 31, 2019, the amounts payable under the Supplemental Plan, would have been as follows: Mr. Guldner — $1,952,646; Mr. Hatfield — $3,659,063; Mr. Bement — $2,991,274; Mr. Froetscher — $5,363,844 and Mr. Smith — $0. 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 immediately and (2) the Account Balance Formula is paid in the form of an immediate lump sum to his spouse. Messrs. Guldner, Hatfield, Bement, Froetscher and Smith would have received $2,256,938; $4,578,566; $3,739,428; $4,474,574 and $0, respectively, in the event of a Termination Event other than death due on December 31, 2019, and these amounts are based on the assumption that the benefit would be payable in five-year installment payments beginning on January 1, 2020. 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 is deemed to have been employed through the end of the performance period (with payout based on actual performance results). In the case of the recipient’s retirement after reaching age 60 with five years of service, but not otherwise qualifying for Early Retirement or Normal Retirement under the Retirement Plan (a “Late Career Employee”), any performance share payout will vest pro-rata based on the number of days the recipient was employed during the performance period compared to the total number of days in the period. 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 the death or disability of a Retirement Qualified Employee or a Late Career Employee, the employee is deemed to have been employed through the end of the performance period (with payout based on actual performance results). 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. If a Retirement Qualified Employee retires, the RSUs will fully vest and will be payable on the dates and in the percentages specified in the vesting schedule. If a Late Career Employee retires, the recipient will receive a pro-rata payout of the portion that would have released on the next vesting date based on the number of days the recipient was employed from the last vesting date. If a Retirement Qualified Employee or a Late Career Employee 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. 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. 82      Table of Contents Executive Compensation 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. 2020 Proxy Statement 95 Table of Contents EXECUTIVE COMPENSATION 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 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 the officer would have received if the officer had survived. Pursuant to the Change of Control Agreement, each of the NEOs is obligated to hold in confidence any and all information in his possession as a result of his 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 and 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. 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 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, but 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 July 31, 2007 (and with respect to Messrs. Hatfield and 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 combines with any other corporation such that 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, but 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 July 31, 2007 (and with respect to Messrs. Hatfield, Guldner, and Schiavoni 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 2019 Proxy Statement     83 Table of Contents Executive Compensation 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. 96 Table of Contents EXECUTIVE COMPENSATION Each of the agreements terminates 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 into a trust sufficient funds to pay obligations under the DCP, 2005 Plan and the Supplemental Plan in the case of an actual or potential change of control. Mr. Brandt could receive certain termination payments under his Consulting Services Agreement. The Consulting Services Agreement may be terminated with or without cause by either Pinnacle West or Mr. Brandt upon 30 days’ written notice. If the Consulting Services Agreement is terminated (i) by Mr. Brandt for any reason other than due to death or disability or (ii) by the Board for cause prior to the end of the Retention Period, Mr. Brandt will receive the Monthly Fee for only the month in which the Consulting Services Agreement is terminated and he will not be entitled to receive the Final Fee. If the Consulting Services Agreement is terminated prior to the end of the Retention Period due to (i) Mr. Brandt’s death or disability or (ii) by the Board for any other reason, including without limitation as a result of a change of control, Mr. Brandt or his estate, as appropriate, will receive all of the unpaid Monthly Fees for the remainder of the Retention Period and the Final Fee in a single lump sum within 30 days following the date on which the Consulting Services Agreement is terminated. 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, 2019. 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 executive officer; ifBoard’s ability to override the six months advance notice is not given,vesting). ● Retirement benefits payable to Messrs. Hatfield, Bement and Froetscher include full vesting of outstanding performance shares (at the agreements will continue for successive one-year periods until the notice is given. The Company is required to deposit into a trust sufficient funds to pay obligations under the DCP, 2005 Plantarget level) and the Supplemental PlanRSUs, plus, in the case of anall cases where applicable, dividend equivalents. Mr. Brandt retired in November 2019 so this reflects actual or potential change of control. The following tables quantify the amounts that would have beenwere triggered upon his retirement. ● Death or disability benefits payable to each NEO ifMessrs.

In the tables: ● We assume full vesting of outstanding performance shares (at the target level), RSUs and the 2017 CEO Performance-Contingent Award upon a change of control. The performance shares, RSUs, plus, where applicable, dividend equivalents, and the 2017 CEO Performance-Contingent Award 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).all cases where applicable, dividend equivalents. ● Retirement benefits payable to Messrs. Brandt, Hatfield, Bement and Froetscher include full vesting of outstanding performance shares (at the target level) and RSUs, plus, in all cases where applicable, dividend equivalents, and the 2017 CEO Performance-Contingent Award for Mr. Brandt. The terms of the 2017 CEO Performance-Contingent Award for Mr. Brandt provide that if Mr. Brandt’s employment with the Company terminates by normal retirement between March 1, 2018 and February 28, 2019, then Mr. Brandt will receive (i) 50% of the award subject to a determination by the Committee that the (A) ROE condition, (B) 2017 earnings threshold and (C) Year 1 Milestones each have been met, plus (ii) up to an additional 50% of the award as the Committee may determine if at the time of the normal retirement, the Board has selected and elected Mr. Brandt’s successor. Although a range of payments between $2 million and $4 million is possible, based on the SEC rules, we believe it is appropriate to include the full $4 million in the below table. Mr. Schiavoni retired in August 2018 so this reflects actual amounts that were triggered upon his retirement. ● Death or disability benefits payable to Messrs. Brandt, Hatfield, Bement, and Froetscher, include full vesting of outstanding performance shares (at the target level) and RSUs, plus, in all cases where applicable, dividend equivalents, and the 2017 CEO Performance-Contingent Award for Mr. Brandt. The terms of the 2017 CEO Performance-Contingent Award for Mr. Brandt provide that if Mr. Brandt’s employment with the Company terminates by reason of death or if the Committee determines that Mr. Brandt is suffering from a disability between March 1, 2018 and February 28, 2019, then Mr. Brandt will receive the full 2017 CEO Performance-Contingent Award. ● All other termination events payable to Mr. Brandt include the full vesting of the 2017 CEO Performance-Contingent Award. The terms of the 2017 CEO Performance-Contingent Award for Mr. Brandt provide that if Mr. Brandt’s employment with the Company is terminated by the Board without cause between March 1, 2018 and February 28, 2019, then Mr. Brandt will receive the full 2017 CEO Performance-Contingent Award. 2020 Proxy Statement 97 84      Table of Contents EXECUTIVE COMPENSATION 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, 2019: Donald E.

For 2019 the median of the annual total compensation of all employees of our Company (other than our CEO) was $132,212 and the prorated total annual compensation of our former CEO and current CEO, as reported in the Summary Compensation Table in this Proxy Statement, was $11,882,550. Based on this information and using the required calculation methodology defined in Item 402(u) of Regulation S–K, for 2019, the ratio of the annual total compensation of our CEO to our median employee’s annual total compensation was 90 to 1. As permitted by Item 402(u) of Regulation S-K, for fiscal year 2019 we used the same median employee for the pay ratio as was used for the pay ratio in the Proxy Statement for fiscal year 2017. We determined that during 2019, as compared to 2018, 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, 2017, our employee population consisted of approximately 6,303 individuals, all of which were located in the United States. This population consisted of our full-time, part-time, temporary and seasonal employees. ● 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 APS Incentive Plans of our employees as reflected in our payroll records on December 31, 2017. ● 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. ● Once we identified our median employee, we combined all of the elements of such employee’s compensation for 2019 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $132,212. The difference between such employee’s salary, wages, overtime and premium pay, and an estimated cash incentive assuming a target payout under the APS Incentive Plan 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 APS Incentive Plans and the estimated aggregate change in the actuarial present value from December 31, 2018 to December 31, 2019 of the employee’s accumulated benefits payable under all defined pension plans. ● With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of our 2019 Summary Compensation Table included in this Proxy Statement for both our former CEO, Mr. Brandt and our current CEO, Mr. Guldner and prorated the total compensation for each by the period of time they each held the postion of CEO during 2019. 100 Table of Contents Executive CompensationAUDIT MATTERS Mark A.

In the event the shareholders fail to ratify the appointment, the Audit Committee may reconsider this appointment. Even if the appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent accounting firm at any time during the year if the Audit Committee determines that such a change would be in the Company’s and the shareholders’ best interests. The Independent Accountant2020 The Audit Committee evaluates the selection of the independent accountant each year, and has appointed D&T, independent accountant, to examine the Company’s financial statements for the year ending December 31, 2019, and, pursuant to Proposal 3, has requested shareholder ratification of this appointment. The Audit Committee has discussed the qualifications and performance of D&T and believes that the continued retention of D&T to serve as the Company’s independent accountant is in the best interest of the Company and its shareholders. In making the determination to retain D&T for 2019, The Audit Committee has appointed Deloitte & Touche LLP (“D&T”) as the Company’s independent accountant for the year ending December 31, 2020 and, as a matter of good corporate governance, has directed management to submit such appointment for ratification by the shareholders at the Annual Meeting.

The Audit Committee has discussed the qualifications and performance of D&T and believes that the continued retention of D&T to serve as the Company’s independent accountant is in the best interest of the Company and its shareholders. In making the determination to retain D&T for 2020, the Audit Committee considered, among other things: ● D&T’s technical expertise, particularly with respect to the complex area of utility regulatory accounting; ● Management’s and D&T’s review of D&T’s historical and recent performance; ● The quality and candor of D&T’s communications with the Audit Committee and management; ● D&T’s independence and tenure as our auditor, including the benefits and independence risks of having a long-tenured auditor, and controls and processes that help ensure D&T’s independence (see the additional information below); ● How effectively D&T demonstrated its independent judgment, objectivity, and professional skepticism; ● External data on audit quality and performance, including the annual Public Company Accounting Oversight Board (“PCAOB”) report on D&T, which is reported on by D&T, and reviewed by the Audit Committee; and ● The fees paid to D&T, which are reviewed and approved by the Audit Committee and then monitored by the Audit Committee throughout the year. D&T served as the Company’s independent accountant for the year ended December 31, 2018. Representatives of that firm are expected to participate in the Annual Meeting. These representatives will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions. 88      Table of Contents Audit Matters Benefits of a Long-Tenured Independent Accountant D&T has served as the independent accountant for Pinnacle West since its inception in 1985, and APS since 1932. The Committee carefully considered the tenure of D&T as our independent accountant in making its decision to select D&T as the independent accountant for 2019, including the following benefits that come with long-tenure: ● Through more than 80 years of experience with the Company and APS, D&T has gained institutional knowledge of and deep expertise regarding our business operations, including the complexities of a business that is highly regulated at both the state and federal level, our accounting policies and practices and our internal controls over financial reporting; and ● Bringing on a new auditor requires a significant time commitment that could result in additional costs to the Company as well as distract management’s focus on financial reporting and internal controls. Accountant’s Independence Controls In further making its selection of D&T as the independent accountant for 2019, the Committee took into account the following controls over D&T: ● The Audit Committee’s oversight of D&T, which included meeting with D&T at every regular in-person meeting in 2018, private meetings from time to time as requested by the Audit Committee members, and a committee-directed process for selecting the lead partner; ● Pre-approval policies of all services performed by D&T for the Company, and allowing the engagement of D&T only when the Audit Committee or its Chair believes D&T is best suited for the job; ● D&T conducts periodic internal quality reviews of its audit work and rotates lead partners every five years; and ● As an independent public accounting firm, D&T is subject to PCAOB inspections, independent peer reviews, and PCAOB and SEC oversight. Pre-Approval Policies As part of its oversight responsibility with respect to the independent accountant and in order to assure that the services provided by the independent accountant do not impair the independent accountant’s independence, the Audit Committee has established pre-approval policies with respect to work performed by D&T for the Company. Under that policy, the Audit Committee pre-approves each audit service and non-audit service to be provided by D&T. The Audit Committee has delegated to the Chair of the Audit Committee the authority to pre-approve audit and non-audit services to be performed by D&T if the services are not expected to cost more than $50,000. Each audit and non-audit service presented to the Chair for pre-approval must be described in sufficient detail so that the Chair knows precisely what services the Chair is being asked to pre-approve so that he can make a well-reasoned assessment of the impact of the service on the independent accountant’s independence. The Chair must report any pre-approval decisions to the Audit Committee at its next scheduled meeting. All of the services performed by D&T in 2018 for the Company were pre-approved by the Audit Committee consistent with the pre-approval policy. 20192020 Proxy Statement     89 Table of Contents Audit Matters101 Audit Fees The following fees were paid to D&T for the last two fiscal years: Types of Service 2017 ($) 2018 ($) Audit Fees(1) 2,813,182 2,894,318 Audit-Related Fees(2) 366,083 374,903 Tax Fees 0 0 All Other Fees 0 0 (1) The aggregate fees billed for services rendered for the audit of annual financial statements and for review of financial statements included in Reports on Form 10-Q.

The proposal and supporting statement, for which the Board of Directors accepts no responsibility, is set forth below. Reduce Ownership Threshold to Call Special Shareholder Meetings The Board of Directors opposes the shareholderrecommends a vote AGAINST this proposal for the reasons set forth following the shareholder proposal. Proposal 4 – Special Shareholder Meetings Resolved, Shareowners ask our board to take the steps necessary (unilaterally if possible) to amend our bylaws and each appropriate governing document to give holders in the aggregate of 10% of our outstanding common stock the power to call a special shareowner meeting (or the closest percentage to 10% according to state law). This proposal does not impact our board’s current power to call a special meeting. Special shareholder meetings allow shareholders to vote on important matters, such as electing new directors that can arise between annual meetings. This proposal topic won more than 70%-support at Edwards Lifesciences and SunEdison. This proposal topic, sponsored by William Steiner, also won 78% support at a Sprint annual meeting with 1.7 Billion yes-votes. Nuance Communications, Inc. (NUAN) shareholders gave 94%-support in February 2018 to a rule 14a-8 proposal calling for 10% of shareholders to call a special meeting. It is important that our company goes the extra mile and adopts an ownership threshold of 10%. Some companies have adopted an ownership threshold of 25% which can be unrealistic. An ownership threshold of 25% can mean that more than 50% of shareholders must be contacted during the perscribed [sic] Mr. John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, a beneficial owner of 50 shares of common stock of the Company, the proponent of a shareholder proposal, has stated that he intends to present a proposal at the Annual Meeting. The proposal and supporting statement, for which the Board of Directors accepts no responsibility, is set forth below. The Board of Directors opposes the shareholder proposal for the reasons set forth following the shareholder proposal. Proposal 4 – Special Shareholder Meetings Resolved, Shareowners ask our board to take the steps necessary to amend our bylaws and each appropriate governing document to give the owners of a total of 10% of our outstanding common stock the power to call a special shareowner meeting (or the closest percentage to 10% according to state law). This proposal does not impact our board’s current power to call a special meeting. Pinnacle West shareholders permanently lack the power to act by written consent. Adoption of this proposal topic could include a provision that a 20% stock ownership threshold would apply if a single shareholder calling for a special meeting owned 10% or more of Pinnacle West Capital stock. Special shareholder meetings allow shareholders to vote on important matters, such as electing new directors that can arise between annual meetings. This proposal topic, sponsored by William Steiner, won 78% support at a Sprint annual meeting. This proposal won 46%-support at the 2019 Pinnacle West Capital annual meeting without the above 20% stock ownership threshold carve out. The 2019 proposal also received majority support from the shareholders who had access to independent proxy voting advice. The current stock ownership threshold of 25% can mean that more than 50% of shareholders must be contacted during the prescribed short window of time to simply call a special meeting. Plus many shareholders, who are convinced that a special meeting should be called, can make a small paperwork error that will disqualify them from counting toward the ownership threshold that is needed for a special meeting. Plus we will never have a right to act by written consent since our company is incorporated in Arizona which is lax in not giving shareholders any right to act by written consent. Any claim that a shareholder right to call a special meeting can be costly - may be moot. When shareholders have a good reason to call a special meeting - our board should be able to take positive responding action to make a special meeting unnecessary. Shareholder proposals such as this have taken a leadership role to improve the corporate governance rules of our company. For instance a shareholder proposal by Emil Rossi resulted in our company adopting one-year terms for our directors to replace the previous laidback 3-year terms. 94      Table of Contents Shareholder Proposal2020 Proxy Statement And there is more work for shareholders to do since we have 4 directors who each have from 18 to 23-years long-tenure. Long-tenure is the opposite of director independence. These directors also had a bloated influence on our most important board committees - holding all the seats on the corporate governance committee. Please vote yes: Special Shareholder Meetings - Proposal 4 Board of Directors Response: The Board of Directors has carefully reviewed the proposal and recommends that the shareholders vote AGAINSTit. Our shareholders already have the right to call special shareholder meetings Almost nine years ago, after thoughtful deliberation, the Board of Directors recommended, and shareholders overwhelmingly approved, amendments to the Company’s Bylaws to adopt robust and well-balanced special meeting provisions. Those provisions give shareholders holding 25% or more of the Company’s outstanding shares of common stock the right to call special meetings, provided certain requirements are met. The Board strongly believes that the current 25% threshold is a reasonable and meaningful threshold that balances the shareholders’ ability to call a special meeting with not forcing Pinnacle West to expend significant time and money on a special meeting that only a small minority of our shareholders want. Based on the number of shares held on December 31, 2018,two of our shareholders can meet a threshold of 10% acting entirely alone. At a threshold of 25%, three of our shareholders acting together can call a special meeting. Moreover, a 25% threshold is also the same as, or lower than, the special meeting rights at 76.12% of 469 S&P 500 companies surveyed by FactSet. Reducing the threshold to 10% could cause Pinnacle West to spend time and resources on a special meetingeven if holders of up to 90% of our shares do not want a special meeting. If the proposal were adopted, a relatively small minority of shareholders—potentially with narrow, short-term interests—could call an unlimited number of special meetings, without regard to how the direct costs and other burdens might impact the Company’s future success or the interests of the vast majority of shareholders. Holding a special meeting could cost thousands of dollars. The shareholder proponent dismisses the cost factor by arguing that if a special meeting is called, the Board should be able to take positive responding action to make a special meeting unnecessary. Apparently the proponent believes this is the case even if holders of 90% of our shares are against the action to be taken. We believe it would be challenging to meet our fiduciary duty if we acted in such a manner. Special meetings also demand significant attention from the Board of Directors and senior management and they disrupt normal business operations. As a result, we believe special meetings should be limited to when there are urgent and important strategic matters or profound fiduciary concerns. We have established multiple governance mechanisms to ensure accountability of the Board and management to shareholders In addition to the existing right of shareholders to call a special meeting, the Board has in place robust corporate governance policies that provide shareholders with a meaningful voice to communicate their priorities to the Board and management. These policies include the opportunity to elect directors annually with a director resignation policy, the opportunity to vote annually on the advisory “say-on-pay” vote on executive compensation, no supermajority voting provisions, and a shareholder proxy access right as described on page 14 of this Proxy Statement. In addition, Pinnacle West regularly engages with shareholders to solicit and discuss their views on governance, executive compensation, and other matters, and feedback received from shareholders as part of our engagement program is provided to the Board. Our shareholder engagement program is described on page 25 of this Proxy Statement. Our strong corporate governance policies and practices, including the ability of a reasonable minority of shareholders to call special meetings, already provide our shareholders with a significant ability to raise important matters with the Board and senior management. Accordingly, we believe that this shareholder proposal is not in the best interests of Pinnacle West and its shareholders, and for the reasons described above,the Board recommends that shareholders vote AGAINST this shareholder proposal. 2019 Proxy Statement     95107 Table of Contents Proxy Statement – General Information SHAREHOLDER PROPOSAL Plus we will never have a right to act by written consent since our company is incorporated in Arizona which is lax in not giving shareholders any right to act by written consent. Any claim that a shareholder right to call a special meeting can be costly – may be moot. When shareholders have a good reason to call a special meeting – our board should be able to take positive responding action to make a special meeting unnecessary. Shareholder proposals such as this have taken a leadership role to improve the corporate governance rules of our company. For instance a shareholder proposal by Emil Rossi resulted in our company adopting one-year terms for our directors to replace the previous lax 3-year terms. And there is more work for shareholders to do since we have 3 directors who each have more than 20-years long-tenure. Long-tenure is the opposite of director independence. These directors also had a bloated influence on an important board committee – holding all the seats on the corporate governance committee. Perhaps shareholders are becoming impatient with these super long-tenured directors because Kathryn Munro, our Lead Director with 20-years long-tenure, was rejected by more shares than any other Pinnacle West director in 2019. Please vote yes: Special Shareholder Meetings – Proposal 4 Board of Directors Response The Board of Directors has carefully reviewed the proposal and recommends that the shareholders voteAGAINST it. Our Shareholders Already have the Right to Call Special Shareholder Meetings In 2019 we received a substantially similar proposal from this proponent requesting that we reduce the threshold to call a special meeting to 10% from 25%. At the 2019 Annual Meeting, shareholders voted in favor of management, rejecting the proposal by a margin of 7.2%. As part of our annual shareholder engagement program, we discussed the topic with shareholders to get a better understanding of their preferences with regards to the threshold to calling a special meeting. As a result of these discussions, we found that there was no consensus from our shareholders as to what they believed the proper threshold should be, though a majority of them did not believe 10% was the proper threshold, as reflected in the 2019 vote results. However, during our conversations with shareholders, some shareholders did express a preference of a threshold less than 25%. As a result of this engagement with our shareholders, our Board voted to address these preferences. In February 2020, after thoughtful deliberation, the Board of Directors voted to amend the Company’s Bylaws to reduce the threshold required to call a special meeting. Shareholders holding 15% or more of the Company’s outstanding shares of common stock have the right to call special meetings, provided certain conditions and requirements are met, including a one-year holding period. The Board strongly believes that the current 15% threshold is a reasonable and meaningful threshold affording shareholders a significant right and is part of an entire suite of rights that the Company provides to its shareholders. 108 Table of Contents SHAREHOLDER PROPOSAL We Have Established Multiple Governance Mechanisms to Ensure Accountability of the Board and Management to Shareholders In addition to the existing right of shareholders to call a special meeting by shareholders holding 15% of the Company’s outstanding stock, the Board has in place robust corporate governance policies that provide shareholders with a meaningful voice to communicate their priorities to the Board and management. While the Proponent dismisses or ignores these rights, they are meaningful opportunities for shareholders to voice their concerns. These rights include: ● Annual director elections with a director resignation policy; ● Time, Date and Place The Company’s 2019 Annual Meeting of Shareholders (“Annual Meeting”) will be held at 10:30 a.m., Mountain Standard Time, on Wednesday, May 15, 2019.

In counting the votes to determine whether a quorum exists, shares that are entitled to vote but are not voted at the direction of the beneficial owner (called abstentions) and votes withheld by brokers in the absence of instructions from beneficial owners (called broker non-votes) will be counted for purposes of determining whether there is a quorum.

Vote Required 2019 Proxy Statement     97 Table of Contents Proxy Statement – General Information Vote Required Election of directors Directors Individuals receiving the highest number of votes will be elected. The number of votes that a shareholder may, but is not required to, cast is calculated by multiplying the number of shares of common stock owned by the shareholder, as of the Record Date, by the number of directors to be elected. Any shareholder may cumulate his or her votes by casting them for any one nominee or by distributing them among two or more nominees. 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 on the voting instruction form.

This resolution is not intended to address any specific item of compensation, but rather the overall compensation of the NEOs and the compensation philosophy, policies and procedures described in this Proxy Statement. Because your vote is advisory, it will not be binding on the Board or the Company. The Board will review the voting results and take them into consideration when making future decisions regarding executive compensation. Abstentions and broker non-votes will have no effect on the outcome of this proposal. We will hold an advisory vote on say-on-pay on an annual basis until we next hold an advisory vote of shareholders on the frequency of such votes as required by law.

This obligation is set forth in writing in our Statement of Policy Regarding Related Party Transactions (the “Policy”). To identify Related Party Transactions, as defined in the Policy, each year the Company requires our directors and officers to complete director and officer questionnaires identifying any transactions with the Company in which a Related Party has an interest. We review Related Party Transactions due to the potential for a conflict of interest. A conflict of interest occurs when an individual’s private interest interferes, or appears to interfere, in any way with our interests. The Code of Ethics requires all directors, officers, and employees who may have a potential or apparent conflict of interest to notify the Company’s management. In addition, the Policy specifically provides that any Related Party Transaction must be approved or ratified by the Corporate Governance Committee. A “Related Party Transaction” is any transaction or a series of similar transactions in which the Company or any of its subsidiaries is or was a participant, where the amount involved exceeds $120,000 in the aggregate, and in which any Related Party has a direct or indirect material interest, other than: ● Transactions in which rates or charges are fixed in conformity with law or governmental authority (such as APS rates approved by the ACC); ● Transactions in which the rates or charges are determined by competitive bid; or ● The payment of compensation by the Company to the executive officers, directors, or nominees for directors. ● Based on the Policy, SEC rules, and our review, we had no Related Party Transactions in 2018.

Glynis A. Bryan, a Director since February 2020, is the Chief Financial Officer of Insight Enterprises, Inc. (“Insight”). Insight is a technology company and a vendor of APS providing information technology services and computer hardware and software products. For these products and services, APS paid less than $6,700,000 to Insight in 2019, which is less than 1% of the Company’s and Insight’s revenues for 2019.
