In addition to delivering exceptional financial performance, we continue to focus on our sustainability efforts, fostering diversity and supporting our communities. Our usage of reclaimed water is a prime example of a sustainable balance and exemplifies our focus on the water-energy nexus.

A MESSAGE FROM OUR LEAD DIRECTORLead Director

Dear Fellow Shareholders,

On behalf of the Board, I thank you for your investment in Pinnacle West. As we approach our 2020 Annual Meeting, I take this opportunity to provide you with an update on how your Board is approaching and addressing key areas of shareholder value, management succession planning, and board refreshment. Through these areas, your Board is positioning Pinnacle West for continued sustainable growth.

DRIVING SHAREHOLDER VALUE

As directors of Arizona’s largest and longest-serving electric company, we view operational excellence as paramount to long-term value creation for our shareholders. Our management team continues to drive outstanding operational execution while growing our business and leveraging technology to promote a long-term sustainable energy future. As Jeff notes in his letter, during 2019 our total shareholder value underperformed our historical track record. We believe Jeff and his management team have the right strategy in place to drive shareholder value performance and the Board will continue to focus on strategic matters of importance to our Company, including operational excellence, customer service and shareholder value.


EXECUTING ON OUR MANAGEMENT SUCCESSION PLANNING PROCESS

In August 2019, we announced that Jeff Guldner would succeed Don Brandt as Chairman, CEO and President of Pinnacle West and as Chairman of the Board and CEO of APS, effective November 2019. This seamless CEO transition reflects the very deliberate succession and development plan overseen by the Board, who remains focused on building a sustainable leadership pipeline. Jeff, who joined us in 2004, was promoted to the position of President of APS in 2018 where he had responsibility for all aspects of APS, excluding nuclear generation. He also served as Executive Vice President, Public Policy of Pinnacle West. Given Jeff’s long tenure, as well as his operating experience and strong background in legal and regulatory matters, your Board is confident that Jeff and his management team will provide steady and thoughtful leadership.

“This seamless CEO transition reflects the very deliberate succession and development plan overseen by the Board, who remains focused on building a sustainable leadership pipeline.”

On January 21, 2020, Maria Lacal took over as Executive Vice President and Chief Nuclear Officer, succeeding Bob Bement in that role. Maria joined APS in 2007 as Director of Strategic Projects at Palo Verde Generating Station. In 2011, she was promoted to Vice President of Operations Support and subsequently promoted to Senior Vice President, Regulatory and Oversight in 2016. Prior to joining APS, she served as Director of Operations Support for the nuclear division of Florida Power & Light Company

A MESSAGE FROM OUR LEAD DIRECTOR

and held other management positions at Turkey Point Nuclear Plant. She becomes only the second woman in the United States to be named a Chief Nuclear Officer and the first at Palo Verde, the nation’s largest energy producer for 27 consecutive years.

With a goal to align operations to support a future focused on customers, clean energy, economic development throughout the communities we serve, and sustainable growth for the Company, APS and Arizona, the Board, working with Jeff Guldner, made additional changes to the management team. We promoted Daniel Froetscher to the position of President and Chief Operating Officer of APS. Jim Hatfield was promoted to the position of Executive Vice President and Chief Administrative Officer of Pinnacle West and APS, and Ted Geisler was promoted to the position of Senior Vice President and Chief Financial Officer of Pinnacle West and APS. Ted has been Vice President and Chief Information Officer of APS since February 2018. He previously held the positions of: General Manager, Transmission and Distribution Operations and Maintenance of APS; Director, Investor Relations of Pinnacle West; and Director, Transmission Operations and Maintenance of APS. Ted possesses the skill set we believe is needed to be an effective and impactful CFO, such as having a deep understanding of our business and industry, financial foresight, financial competence and a well-balanced perspective on risk. We have strategically selected successors for our management team who we believe will lead our Company successfully into the future with continued strong and sustainable performance.

ROBUST BOARD REFRESHMENT PLANNING PRACTICES

In addition to our deliberate and thoughtful approach to management succession planning, the Board has been equally mindful of its own refreshment practices to facilitate an orderly transition of Board members. Since we adopted a Director Retirement Policy in 2016, we have had one Board member retire and we have added three new members to the Board. This year, one of our current Directors, Mike Gallagher, is retiring under our policy and will not stand for re-election at the Annual Meeting. We thank him for his years of service. Our Company and our Board have benefitted greatly from his counsel and guidance.

In February 2020, we added Glynis Bryan to our Board. With more than 20 years of CFO experience, Glynis brings additional financial, audit and accounting, and public company board experience to our Board, supplementing our current knowledge base and positioning us for seamless transitions as our Board refreshment process continues.

“As part of our Board refreshment planning process, we have developed and continue to update a matrix of our Board members’ skills and experience, assessing where we need to augment certain skills and experience due to upcoming Board retirements and/or our future long-term plans, while continuing our focus on diversity among our members.”

A MESSAGE FROM OUR LEAD DIRECTOR

In February 2020, we reevaluated our Director Retirement Policy. The policy as drafted could have resulted 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 Iif, 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 or 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 likeexperience multiple years with more than one member scheduled to thank you for your investmentretire. We believe that it is in Pinnacle West.the best interests of the Company to better stagger these retirements while Jeff gets more experience in the CEO role. As such, we approach our 2018created 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 I would likeof 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 take this opportunity to provide you withthe 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 update on how your Board is approaching and addressing key areas of shareholder interest, particularly with respect to our governance and compensation practices.

Driving Shareholder Value Creation and Promoting a Sustainable Energy FutureAnnual Meeting or otherwise.

As directorspart of Arizona's largestour continued Board refreshment planning process, we have developed and longest-serving electric company, we view operational excellence as paramount to long-term value creation for our shareholders, and our long-term strategy reflects this focus. Our management team continues to drive outstanding operational execution while growing our business and leveraging technology to promote a long-term sustainable energy future. These efforts have resulted in strong returns for our shareholders: annualized total shareholder return of 18.8% since May 1, 2009, which was when Don Brandt took over as CEO. This exceeds the annualized returns of the S&P 1500 Electric Utilities Index of 11.8% and the S&P 500 Index of 16.2%. We also continue to be recognized forupdate a matrix of our safetyBoard members’ skills and sustainability leadership:

•
2017 was another successful yearexperience, assessing where we need to augment certain skills and experience due to upcoming Board retirements and/or our future long-term plans, while continuing our focus on diversity among our members. We require our outside director search firm to make diversity a focal point of all our searches, with regarda continued emphasis on women and diverse candidates.

SHAREHOLDER-INFORMED CHANGES

Shareholder input is very valuable to safety, with APS remaining in the top decile for safety performance in the U.S. electric utilities industry; and

•
We earned a "Leadership" rating from CDP, a not-for-profit entity that reports on environmental performance, for climate change and water management — one of only two U.S. utilities to earn the highest rating in both categories.

Board-Driven Shareholder Engagement

Board’s decision-making. Pinnacle West has an established shareholder engagement program which was further augmented during 2017 in response to what the Board considered a disappointing level of shareholder support for our annual advisory vote on compensation. Shareholder input is very valuable to the Board's decision-making, andwhere we wanted to ensure we had the opportunity to engage directly with our shareholders throughout the year to discuss issues or concerns and to answer questions. We learn a great deal through our engagement program. Last year we had a shareholder proposal seeking to lower the percent of shares required to call a special meeting of shareholders to 10%. You did not pass that proposal. In our off-season outreach, it became evident that there is no clear consensus on what is the correct percentage. In recognition of the fact that our shareholders support various percentages ranging from 25% to 10%, and that although the proposal did not pass last year it did have significant support, we have responded by lowering the percentage to 15%. We continue to believe that 10% is too low for the reasons we set forth in the Proxy Statement starting on page 108.

We are pleased to report two consecutive years of strong say-on-pay support, with 93% in 2018 and over 95% in 2019, which is the result of our engagement with you. We thank you for your input and your support, and we invite you to read more about our compensation governance and broader Board practices. As Lead Director and member of the Human Resources Committee, I participated on behalf of the independent directors in a number of the shareholder discussions during the fall of 2017. These conversations were valuable to our Board, spurred important discussions, and have resulted in changes and disclosure enhancements that you will see detailedprogram in this Proxy Statement.Statement starting on page 48.

Shareholder-Informed Compensation Program Changes

As a Board, we are committed to an executive compensation program that establishes strong pay for performance alignment and supports our ability to attract and retain a talented and proven leadership team. We seek to design compensation programs that support our long-term goals, reward achievement of long-term performance and align with the interests and feedback of our shareholders. To this end, our compensation programs have evolved with our business,

2020 Proxy Statementv

Table of Contents

including several changes made in 2016. Following shareholder discussions in 2017, we have made further changes to our program that we believe will create even greater alignment between our executives and the performance of our Company, and changes to our program and disclosures that reflect the feedback we have received from our shareholders. These changes are detailed in the Compensation Discussion and Analysis of this Proxy Statement and include:A MESSAGE FROM OUR LEAD DIRECTOR

•
Increase in the proportion of performance shares in our CEO's and Executive Vice Presidents' 2018 long-term incentive awards from 60% to 70% (reducing the percent of restricted stock units from 40% to 30% as well);

BOARD OVERSIGHT OF STRATEGY AND THE BUSINESS

•
Revised 2018 metrics in certain key business units to better align with our priorities and emphasize top-quartile or above performance;

•
Adoption of a formal clawback policy;

•
Enhanced CD&A disclosures;

•
Additional transparency into our metric setting practices;

•
Redesigned annual incentive disclosure; and

•
Additional detail on how we select our peer group.

These structural and disclosure enhancements are directly in response to feedback we received from our shareholders.

Thoughtful and Systematic Management Succession Planning Process

As you would expect for a company with a highly skilled and long-tenured management team, the Board is very engaged in succession planning to ensure we are building a sustainable leadership pipeline. CEO and senior leadership succession planning continues to be a focus for the Board, and we have been executing on a very deliberate succession and development plan. Our current management team, under the leadership of Don Brandt, has delivered very strong performance and the Board and its Committees are actively involved in our succession plans for our top talent to ensure we are providing development opportunities that will allow for smooth leadership transitions in the future.

Robust Board Refreshment and Succession Planning Practices

The Board has established strong practices to support regular Board evaluation and refreshment. In 2016, the Board adopted a Director Retirement Policy to facilitate an orderly transition of Board members and implemented a five-year plan to refresh the Board and its leadership. This five-year plan encompasses the following:

•
Development of a matrix of our Board members' current skills and experiences;

•
Evaluation of the skills and experience leaving our Board over the next five years;

•
Assessment of skills and experience needed to guide the company's future long-term plans;

•
Incoming committee chairs are identified one year in advance of assuming chair leadership to ensure proper transition — with Roy Herberger's retirement, Rick Fox will take over as the Chair of the Human Resources Committee effective at the Annual Meeting.

This process helps guide the Board in its recruitment efforts.

Our independent Board members are expected to be active, engaged and contributing members. Our discussions are focused on oversight of Pinnacle West’s business strategy, targeting the Company’s critical areas of focus of shareholder value, operational excellence, environment, customer value, employees, security, and the communities we serve. We are excited about our announcement of our Clean Energy Commitment and our plan to deliver 100% clean energy to our customers by 2050, with a near-term 2030 target of 65% clean energy, with 45% of our portfolio coming from renewable energy.

In 2019 we held a combined total of 35 Board and Board committee meetings, including an all-day session at the Palo Verde Generating Station. In addition to the Board meetings, our Directors have focused on our shareholder engagement program and participated in continuing director education sessions. In addition, Paula Sims and Jim Trevathan recently attended the 2019 Goizueta Directors Institute program “Improving Effectiveness of Nuclear Utility Board Members,” a two-day program designed specifically for directors of companies with nuclear operations by the Institute of Nuclear Power Operations, the National Academy for Nuclear Training, and the Goizueta Business School at Emory University.

“We are excited about our announcement of our Clean Energy Commitment and our plan to deliver 100% clean energy to our customers by 2050, with a near-term 2030 target of 65% clean energy, with 45% of our portfolio coming from renewable energy.”

On behalf of the Board, I want to thank our shareholders for their time and feedback. I am pleased to provide this additional window into the Board'sBoard’s activities in 20172019 and express our commitment to running our business for the long-term value creation for our shareholders. We appreciate your support at our 20182020 Annual Meeting.

Our management team is committed to increasing shareholder value as a top priority. 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.

Upon dialing in, you will need to provide your 16-digit control number.

We continue to believe that the virtual-only format, which we used for the first time last year, is in the best interests of our shareholders, given the time and expense of an in-person meeting compared to the shareholder participation at those meetings. The number of non-employee shareholders actually attending our Annual Meetings of Shareholders has significantly dwindled. For the past five in-person meetings, only about 30 shareholders attended each of the meetings. The meetings, on average, lasted less than 45 minutes, including the formal business portion of the meeting, the remarks by the CEO, a video highlighting the Company's performance, and the question and answer period. A virtual meeting allows all of our shareholders, regardless of location, the ability to participate in the Annual Meeting.

Our virtual meeting will be governed by our Rules of Conduct, which we use for both in-person and virtual meetings. Shareholders at the virtual-only meeting will have the same rights as at an in-person meeting, including the rights to vote and ask questions through the virtual meeting platform.

Selection of Nominees for the Board

The Corporate Governance Committee uses a variety of methods to identify and evaluate nominees for a director position:

Board Size:The Corporate Governance Committee regularly assesses the appropriate size of the Board, including whether any vacancies on the Board are expected due to retirement or otherwise.
Board Knowledge, Skills, Expertise and Diversity:The Corporate Governance Committee considers whether the Board reflects the appropriate balance of knowledge, skills, expertise, and diversity required for the Board as a whole.
Sourcing Candidates:Candidates may be votedconsidered at any point during the Annual Meeting. If you hold shares in the Pinnacle West 401(k) Plan, you will need to submit your voteyear and come to the plan trustee by May 13, 2018 to vote your shares.attention of the Corporate Governance Committee through current Board members, professional search firms or shareholders. The Corporate Governance Committee evaluates all nominees from these sources against the same criteria.

You may change your vote by: re-voting by telephone; re-voting by Internet; or re-voting during the formal business portion of the Annual Meeting. For shares held in your name you may change your vote by re-submitting a signed proxy card. In addition, for shares held in your name, you may also revoke a previously submitted proxy card by filing with our Corporate Secretary a written notice of revocation. For shares for which you are the beneficial owner but not the shareholder of record, you may change your vote by re-submitting a signed voting instruction form to your broker. In addition, for shares for which you are the beneficial owner but not the shareholder of record, you should contact your broker if you would like to revoke your vote.

Your vote is confidential. Only the following persons have access to your vote: election inspectors; individuals who help with the processing and counting of votes; and persons who

need access for legal reasons. All votes will be counted by an independent inspector of elections appointed for the Annual Meeting.

Quorum

The presence, in person or by proxy, of a majority of the outstanding shares of our common stock is necessary to constitute a quorumOther than Ms. Bryan, all Directors were elected at the Annual Meeting. 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. Shares owned by the Company are not considered outstanding or present at the meeting.

Vote Required

Election of 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.

Say-on-Pay vote.    The votes cast "for" must exceed the votes cast "against" to approve the advisory resolution on the compensation disclosed in this Proxy Statement of our NEOs identified on page 44 — the say-on-pay vote. 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.

Ratification of the appointment of the independent accountants.    The votes cast "for" must exceed the votes cast "against" to ratify the appointment of the independent accountants for the year ending December 31, 2018. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

Board Recommendations

The Board recommends a vote:

ü
FOR the election of the nominated slate of directors (Proposal 1);

ü
FOR the approval, on an advisory basis, of the resolution approving the compensation of our NEOs, as disclosed in this Proxy Statement (Proposal 2); and

Proxy Access.INFORMATION ABOUT OUR BOARD AND CORPORATE GOVERNANCE

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."“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 1112 directors, the maximum number of proxy access candidates we would be required to include in our proxy materials is two.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 October 30, 2018November 7, 2020 nor later than the close of business on November 29, 2018.December 7, 2020.

In all cases, shareholders and nominees must also comply with the applicable rules of the Securities and Exchange Commission ("SEC")SEC and the applicable sections of our Bylaws relating to qualifications of nominees and nominating shareholders and disclosure requirements.

Information About Our Board and Corporate Governance

The Board's Leadership Structure

Lead Director.    Kathryn L. Munro serves as the Company's Lead Director and chairs the Corporate Governance Committee. The Lead Director performs the following duties and responsibilities as set forth in our Corporate Governance Guidelines:

•
Serves as a liaison between the Chairman of the Board (the "Chairman") and the independent directors;

•
Advises the Chairman as to an appropriate schedule of Board meetings, reviews and provides the Chairman with input regarding agendas for the Board meetings and, as appropriate or as requested, reviews and provides the Chairman with input regarding information sent to the Board;

•
Presides at all meetings at which the Chairman is not present, including executive sessions of the independent directors (which are regularly scheduled as part of each Board meeting) and calls meetings of the independent directors when necessary and appropriate;

•
Oversees the Board and Board committee self-assessment process;

•
Is available for appropriate consultation and direct communication with the Company's shareholders and other interested parties; and

•
Performs such other duties as the Board may from time to time delegate.

These duties and responsibilities do not, however, fully capture Ms. Munro's active role in serving as our Lead Director. For example, Ms. Munro has regular discussions with the CEO, other members of the senior management team and members of the Board between Board meetings on a variety of topics, and she serves as a liaison between the CEO and the independent directors. Ms. Munro focuses the Board on key issues facing our Company and on topics of interest to the Board. She takes the lead on director recruitment and has a formal annual call with each non-employee director to discuss the Board, its functions, its membership, the individual's plan with respect to his or her continuing Board service, and any other topic the individual desires to discuss with our Lead Director. Her leadership fosters a Board culture of open discussion and deliberation to support sound decision-making. She also encourages communication between management and the Board to facilitate productive working relationships.

Chairman and CEO Positions.    The Chairman is Donald E. Brandt, the Company's President and CEO. The independent directors believe that Mr. Brandt, as an experienced leader with extensive knowledge of the Company and our industry, serves as a highly effective conduit between the Board and management and that Mr. Brandt provides the vision and leadership to execute on the Company's strategy and create shareholder value. The Board believes that separating the roles of the CEO and Chairman and appointing an independent Board Chairman at this time would create an additional level of unneeded hierarchy that would only duplicate the activities already being vigorously carried out by our Lead Director.

Succession Planning and Board Evaluations

Management Succession.    Our Board places a high priority on senior management development and succession planning. While the Corporate Governance Committee has principal responsibility for overseeing CEO and other senior management succession planning, the full Board is actively involved in reviewing our senior management succession plans that will allow for smooth and thoughtful leadership transitions in the future.

Executive succession planning and senior management development were specific areas of focus for the Corporate Governance Committee in 2017. The Corporate Governance Committee engaged in thorough and thoughtful discussions regarding the development and evaluation of current and potential senior leaders, as well as the development of executive succession plans, including succession plans for our CEO position.

Board Succession.Our Board has developed a robust processplan to refresh the Board and its leadership significantly over the next several years and beyond. The processplan 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 processplan 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 5 of this Proxy Statement.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'sCompany’s long-term strategy. This information is taken into account when identifying director nominees during the recruitment process.

Board Evaluations.    The Corporate Governance Committee has established a thorough evaluation process wherein each Director completes a Board evaluation as well as an individual self-evaluation annually. The Board evaluation allows each Director the opportunity to examine and evaluate the Board's composition and effectiveness, competency, accountability, deliberations and administration, and each committee, as well as the opportunity to identify any skills, experience or expertise the Director believes should be represented, or more fully represented, on the Board. The individual self-evaluation asks each Director to evaluate different areas of their performance as a Director, including independence, expertise, judgment and skills. The Board assessment results are reviewed both on a one-year standalone basis and on a three-year basis in order to identify any year-over-year trends. The assessment results are initially reviewedrefreshment is overseen by the Lead Director. The Lead Director then has a formal annual call with each Director to discuss the Board, its functions, its membership, the individual's plan with respect to his or her continuing Board service, and any other topic the individual desires to discuss with our Lead Director. The results of the evaluations and calls are presented to the Corporate Governance Committee, which regularly assesses whether the composition of the Board reflects the knowledge, skills, expertise, and fulldiversity appropriate to serve the needs of the Company.

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 each February. 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.

The Board's Role in Risk Oversight

Top risks discussed by the Board and its committees in 2017 included cybersecurity, data privacy and ownership, physical security, and utility regulation. The Board believes it is important to look at the list fresh each year as part of a diligent risk review.Responsibility for the management of the Company's risks rests with the Company's senior management team. The Board's oversight of the Company's risk management function is designed to provide assurance that the Company's risk management processes are well adapted to and consistent with the Company's business and strategy, and are functioning as intended. The Board focuses on fostering a culture of risk awareness and risk-adjusted decision-making and ensuring that an appropriate "tone at the top" is established. The Board regularly discusses and updates a listing of areas of risk and a suggested allocation of responsibilities for such risks among the Board and the Board committees. The charter for each of our committees requires each committee to periodically review risks in their respective areas. Each committee:

•

Receives periodic presentations from management about its assigned risk areas;

•

Receives information about the effectiveness of the risk identification and mitigation measures being employed; and

•

Discusses their risk reviews with the Board at least annually.

Consistentconcern, both with respect to the requirements ofBoard overall and with respect to individual performance. As performance issues are identified, they are addressed by the NYSE's corporate governance standards, the Audit Committee periodically reviews the Company's major financial risk exposuresLead Director and the steps management has takenChairman as needed.

The Audit Committee also reviews the comprehensiveness of the Board's risk oversight activities and the Company's risk assessment process, and plays a coordinating role designed to ensure that no gaps exist in the coverage by the Board, committeesall 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 risk areas.

The Executive Risk Committee is comprised of senior level officers ofsignificance 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 chaired by the Chief Financial Officer. Among other responsibilities, this Committee is responsiblein process for ensuring that the Board receives timely information concerning the Company's material risks and risk management processes.

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.

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'sCompany’s Corporate Governance Guidelines, upon a substantial change in a director'sdirector’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.

Board and Committee Structure

The Board’s Leadership Structure

LEAD DIRECTOR

Kathryn L. Munro serves as the Company’s Lead Director and chairs the Corporate Governance Committee. The Lead Director performs the following duties and responsibilities as set forth in our Corporate Governance Guidelines:

●Serves as a liaison between the Chairman of the Board (the “Chairman”) and the independent Directors;
●Advises the Chairman as to an appropriate schedule of Board meetings, reviews and provides the Chairman with input regarding agendas for the Board meetings and, as appropriate or as requested, reviews and provides the Chairman with input regarding information sent to the Board;

22

Table of Contents

INFORMATION ABOUT OUR BOARD AND CORPORATE GOVERNANCE

●Presides at all meetings at which the Chairman is not present, including executive sessions of the independent Directors (which are regularly scheduled as part of each Board meeting) and calls meetings of the independent Directors when necessary and appropriate;
●Oversees the Board and Board committee self-assessment process;
●Is available for appropriate consultation and direct communication with the Company’s shareholders and other interested parties; and
●Performs such other duties as the Board may from time to time delegate.

These duties and responsibilities do not, however, fully capture Ms. Munro’s active role in serving as our Lead Director. For example, Ms. Munro has regular discussions with the CEO, other members of the senior management team and members of the Board between Board meetings on a variety of topics, and she serves as a liaison between the CEO and the independent Directors. Ms. Munro focuses the Board on key issues facing our Company and on topics of interest to the Board. She takes the lead on director recruitment and has a formal annual call with each non-employee Director to discuss the Board, its functions, its membership, the individual’s plan with respect to his or her continuing Board service, and any other topic the individual desires to discuss with our Lead Director. Her leadership fosters a Board culture of open discussion and deliberation to support sound decision-making.She also encourages communication between management and the Board to facilitate productive working relationships.

As a former chief executive with significant Board and Chair/Lead Director experience, Ms. Munro has the competency and capability to fulfill the duties of Lead Director. As Lead Director, Ms. Munro is poised to guide the Board during these transformative times of both Board refreshment as well as CEO and other management succession.

CHAIRMAN AND CEO POSITIONS

Upon promoting Jeff Guldner to the position of CEO, the Board also chose to elect him as Chairman of the Board. The Board believes that the Company is in a better position to implement its near- and long-term strategies if the Chairman is also the person directly responsible for the operations executing those strategies. The Board further believes that separating the roles of the CEO and Chairman and appointing an independent Board Chairman at this time would create an additional level of unneeded hierarchy that would only duplicate the activities already being vigorously carried out by our Lead Director.

The independent Directors believe that Mr. Guldner, with his extensive knowledge of the challenges facing the Company and our industry and his open leadership style, will be a highly effective conduit between the Board and management and that Mr. Guldner provides the vision and leadership to execute on the Company’s strategy and create shareholder value without the need for an independent chair. The Board also convenes regularly scheduled executive sessions of the independent directors in order to ensure the independent directors can speak candidly and openly without the presence of management.

Board Committees

The Board has the following standing committees: Audit; Corporate Governance; Finance; Human Resources; and Nuclear and Operating. All of the charters of the Board’s committees are publicly available on the Company’s website (www.pinnaclewest.com). All of our committees conduct a formal review of their charters every other year and as often as any committee member deems necessary. In the years in which a formal review is not conducted, the Board has tasked management with reviewing the

Strategic Framework

The Core serves as the Company's Corporate Governance Guidelines, an individual shall not be eligiblefoundation for all strategic and business initiatives. It is anchored by four pillars that establish the foundation for the way we intend to be nominated for election or re-election as a memberdo 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. APS’s vision is to create a sustainable energy future for Arizona. APS’s mission is to safely and efficiently deliver reliable energy to meet the changing needs of our customers. The critical areas of focus are employees, operational excellence, security, environment, customer value, community, and shareholder value. The framework affirms our corporate values of safety, integrity and trust, respect and inclusion, and accountability. Here is our Core:

The Core is our strategic framework. This is the foundation from which our long-term strategy is built.

The 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 trust and goodwill of our customers and the communities we serve. We recruit and retain great people, and we empower them to be enthusiastic ambassadors for our customers. We respond to 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.


Codes of Ethics

The Human Resources Committee is tasked with establishing the Company’s executive compensation philosophy and reviewing the Company’s plans and programs for the attraction, retention, succession, motivation, and development of the human resources needed to achieve corporate objectives. The Human Resources Committee also reviews the Company’s pension, health, welfare and benefit plans and is responsible for the oversight of risks relating to or arising out of the Company’s compensation and human resources policies and practices. The full Board also receives reports on issues relating to human capital. The Board has multiple opportunities each year to interact directly with employees, including during our annual Board meeting at the Palo Verde Generating Station, during an annual dinner with high-potential employees, and at employee-driven presentations to the Board.

Environmental, Social and Governance

Our Board dedicates a great amount of time to environmental, social and governance matters at the Board and committee level. As an electric utility, environmental matters are at the forefront of our discussions on operations, strategy and risk. The Nuclear and Operating Committee has primary responsibility over environmental matters, though the nomination, the individual has attained the ageBoard also receives reports on matters of 75 years.

HIGHLIGHTS OF CERTAIN RISKS

Two risks monitored by the Board and its committees were as follows:

CATASTROPHIC FIRE EVENT – WILDFIRE RISK
Wildfire risk is always present for the Company given our expansive service territory. Wildfires have the potential to affect not only the communities that APS serves, but also APS’s vast network of electric lines and facilities. The Company uses a proactive, multi-faceted approach to wildfire mitigation, with a central focus on risk assessment, readiness and compliance. Main components of the mitigation strategy include:

●Disabling of automatic reclosers on high risk feeders during fire season;
●Wildland-Urban/Forestry fire risk assessments and prevention measures;
●Wildland-Urban Interface/Defensible Space Around Poles Program;
●Vegetation Management Right-of-Way Program; and
●Transmission Line Clearance Program.

Responsibility for oversight of wildfire risk was allocated to the Finance Committee.

CYBERSECURITY
Cybersecurity continues to be an integral part of APS’s day-to-day business. The risks in this area are constantly expanding and evolving, particularly driven by the increasing sophistication of cyber threats and the growing risk surface presented by new technologies, platforms and other innovations. The Company has implemented cybersecurity measures focused on the layers of criticality around its bulk electrical systems and nuclear systems. The Company continues to embrace an industry-standard approach to cyber risk management, which includes:

●Cyber Incident Response Plan and augmentation of existing internal processes;
●Third-party risk monitoring technology and internal escalation process;
●Collaboration between corporate Information About Security and Palo Verde Cybersecurity;
●APS Cyber Defense Center to detect, respond, contain and recover from cyber attacks;
●Active participation in Electricity Subsector Coordinating Council Cyber Mutual Assistance Program; and
●Consistent application of security controls across all technology solutions and underlying infrastructure.

Responsibility for oversight of cybersecurity risk was allocated to the Nuclear and Operating Committee.

Management Succession

Executive succession planning and senior management development were specific areas of focus for the Corporate Governance Committee over the last several years. Our deliberate and thoughtful succession plan was implemented in 2019, resulting in the election of Jeffrey B. Guldner as Chairman of the Board, President and CEO of the Company and Chairman of the Board and CEO of APS, Daniel T. Froetscher as President and Chief Operating Officer of APS, Maria L. Lacal as Executive Vice President and Chief Nuclear Officer, PVGS of APS, and Theodore N. Geisler as Senior Vice President and Chief Financial Officer of the Company and APS. The implementation of this succession plan is the result of the Corporate Governance Committee engaging with management in thorough analysis and thoughtful discussions, including the development and evaluation of current and potential senior leaders.

Our Board places a high priority on senior management development and succession planning. While the Corporate Governance Committee has principal responsibility for overseeing CEO and other senior management succession planning, the full Board is actively involved in reviewing our senior management succession plans that are designed to provide for smooth and thoughtful leadership transitions in the future.

Given our need for specialized experience, we maintain strong management 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.

Director Qualifications and Selection of Nominees for the Board

Director Qualifications.    The Bylaws and the Corporate Governance Guidelines contain Board membership criteria that apply to nominees recommended for a position on the Board. Under the Bylaws, a director must be a shareholder of the Company. In determining whether an individual should be considered for Board membership, the Corporate Governance Committee considers the following core characteristics:

•
High Standards:  We look for directors that set high standards and expectations for themselves and others and the accomplishment of those standards and expectations.

•
Informed Judgment:  Directors should be thoughtful in their deliberations. We look for directors who demonstrate intelligence, wisdom and thoughtfulness in decision-making. Their decision-making process should include a willingness to thoroughly discuss issues, ask questions, express reservations and voice dissent.

•
Integrity and Accountability:  Directors should act with integrity. We look for directors who have integrity and strength of character in their personal and professional dealings. Our directors should be prepared to be, and are held, accountable for their decisions.

•
Time and Effort:  Directors should spend the necessary time to properly discharge their responsibilities as directors, including reviewing written materials provided to the Board or committee in advance of Board or committee meetings. Directors are expected to be present at all Board meetings, the Annual Meeting of Shareholders, and meetings of committees on which they serve. We also expect our directors to make themselves accessible to management upon request.

•
Other Commitments:  We expect our directors to monitor their other commitments to assure that these other commitments do not impact their service to our Company. Directors may not serve on more than three other boards of public companies in addition to the Pinnacle West Board without the prior approval of the Corporate Governance Committee. A director may not serve as a member of the Audit Committee if they serve on the audit committees of more than three public companies (including the Company) unless the Board determines that such simultaneous service would not impair the ability of such member to effectively serve on the Company's Audit Committee.

•
Stock Ownership:  We expect our directors to have investments in the Company's stock that align with our shareholders. Our directors are expected to comply with our Director Stock Ownership Policy.

The Corporate Governance Committee considers diversity in its selection of nominees utilizing a broad meaning to include not only factors such as race and gender, but also background, experience, skills, accomplishments, financial expertise, professional interests, and the potential contribution of each candidate to the diversity of backgrounds, experience and competencies which the Board desires to have represented. The Corporate Governance Committee considers the following qualities as well:

•
Regulatory and political knowledge is relevant to the Company as the utility industry is heavily regulated and directly affected by public policy and the actions of federal, state and local governmental agencies.

•
Nuclear expertise at the strategic level is important to the Company as we operate, Palo Verde Generating Station, a nuclear power plant and the largest power plant in the United
​

​

    States. As we plan for our future, Palo Verde plays a large role in shaping the Company's business strategy and the future of our generation mix.

•
Understanding of the Company's business environment is a critical attribute in planning our short- and long-term business strategies. Possessing knowledge of the Company's business environment includes not only experience in the broader utility industry, but also experience with factors unique to the Southwest and Arizona, including understanding the business from the perspective of the customer.

•
Large organizational leadership of complex operations provides a broad range of skills and experience beneficial to our decision-making, including human resource management, business strategy, finance and capital allocation.

•
Public company experience, as a member of a public company board or as CEO or other senior leader, gives a director an understanding of many of the structural and business strategy challenges facing a public company. This experience provides invaluable leadership skills in auditing matters, investment strategy and corporate governance.

•
Risk oversight and management skills are essential to the Board's role in overseeing and managing the risk associated with operating in the utility industry.

Selection of Nominees for the Board.    The Corporate Governance Committee uses a variety of methods to identify and evaluate nominees for a director position. The Corporate Governance Committee regularly assesses the appropriate size of the Board, whether any vacancies on the Board are expected due to retirement or otherwise, and whether the Board reflects the appropriate balance of knowledge, skills, expertise, and diversity required for the Board as a whole. In the event that vacancies are anticipated, or otherwise arise, the Corporate Governance Committee may consider various potential candidates. Candidates may be considered at any point during the year and come to the attention of the Corporate Governance Committee through current Board members, professional search firms or shareholders. The Corporate Governance Committee evaluates all nominees from these sources against the same criteria.

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'scompany’s board of directors to make director independence determinations in all other circumstances. The Company'sCompany’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'sCompany’s website (www.pinnaclewest.com)(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.

PROPOSAL 2
Advisory Vote on Executive CompensationThe 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 approving all transactionsthe accompanying tables and narrative, the Company has designed its executive compensation program to align executives’ interests with any related party, which consists of anythose of our directors, director nominees,shareholders, make executives accountable for business and individual performance by putting pay at risk, and attract, retain and reward the executive officers, shareholders owningtalent 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 than 5% of the Company's common stock and, with respect to each of them, their immediate family members and certain entities in which they are an officer or a shareholder, partner, member or other participant who, directly or indirectly, has a substantial ownership interest in or otherwise substantially controls or shares control of such entity (a "Related Party"). This obligation is set forth in writing in our Statement of Policy Regarding Related Party Transactions (the "Policy").

To identify Related Party Transactions, as definedfully discussed 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:CD&A:

•
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 2017.

2017 Rate Review Order.    As an Arizona-based regulated electric utility company, APS periodically submits requests to the ACC for a comprehensive review of our electricity rates. Approval of a rate adjustment enables us to generate revenue with which we fund improvements in our operations and investments that benefit our customers. In June 2016, we initiated our first rate review in five years, and in August 2017, after working with the ACC Staff and key stakeholders, we received approval for our comprehensive rate review. This approval allows for a 3% increase in overall revenues, as well as additional funds for our AZ Sun II rooftop solar program, a refund of surplus of energy efficiency program funds to customers, increased funding for programs assisting limited-income customers, and other key investments in Arizona's energy future. This was an important milestone for us as it allows us to continue making efficient, cost-effective investments while providing safe, reliable service for our customers.

Shareholder Engagement and Board Responsiveness

2017 Shareholder Engagement.    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. We were disappointed with the level of shareholder support for the 2017 say-on-pay vote, and during the fall following our 2017 Annual Meeting:

•
We specifically sought direct feedback on our compensation program from shareholders;

•
Our Lead Director and Human Resources Committee member, Kathy Munro, participated in a number of the meetings with our shareholders to receive their direct feedback and share it with the Board; and

•
We contacted the holders of approximately 50% of shares outstanding and met with the holders of approximately 40% of shares outstanding, including many of our largest institutional shareholders as well as smaller holders to collect a range of perspectives.

2017 Board Responsiveness.    As in prior years, the feedback received from shareholders during this outreach was an important input into the Committee's and Board's review process. While many of the investors that we spoke to believed our compensation structure was well-aligned with performance, we received valuable feedback about how we could improve the program and make it more transparent.

Following thoughtful discussion of shareholder feedback and a review of the compensation program, the Committee made several changes that it believes align with feedback received and further support our commitment to pay-for-performance.

Key 2017 Compensation DecisionsTable 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 year ended December 31, 2017,Human Resources Committee (for purposes of the CommitteeCD&A, the “Committee”), or the Board acting on the Committee’s recommendation, approved the following compensation decisions for our NEOs:

•

2017 Base Salary Adjustments.2019 BASE SALARY ADJUSTMENTS
For fiscal 2017,year 2019, the Committee increased Mr. Brandt'sBrandt’s salary by 3%;3.2% and the Board, acting on the Committee’s recommendation, increased Messrs. Hatfield, Bement, FalckHatfield’s, Bement’s, Froetscher’s and Schiavoni receivedSmith’s base salary increases of between 3.2%-4.4%-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

•
2017 Annual Incentive Award.Our 20172019 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 2017 earnings target at $453$538 million for 2017, essentially2019, relatively flat to 2016the 2018 actual incentive earnings of $452$537.2 million. Likewise, we set Pinnacle's 2017Pinnacle’s 2019 target earnings range such that its projected midpoint was $440$515 million, again essentially flatcompared to Pinnacle's 2016Pinnacle’s 2018 actual incentive earnings of $442$511 million. In both cases, the earnings goals were set while the decision regarding our comprehensive rate review was still pending. Because we had no visibility to how the rate adjustment would ultimately conclude in mid-2017, thereflect modest sales growth and continued focus on effective cost controls.

    Actual earnings targets excluded any potential impact of a rate adjustment.

    Earnings for APS and Pinnacle West for incentive plan purposes were 7%9% and 8% above12% below the 2017 targets,2019 target payouts, respectively, as shown on pages 5766 and 58.67. The improvementdecrease in 2017

2017 CEO Performance-Contingent Award.PERFORMANCE-CONTINGENT AWARD
  As previously disclosed in advance of our 2017 Annual Meeting, inIn March 2017, the Committee granted the CEOMr. Brandt a two-year, performance-based cash award ("(“2017 CEO Performance-Contingent Award"Award”). This award iswas designed to incent Mr. Brandt, a retirement eligible CEO, to remain in his current role while further emphasizing the Board'sBoard’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 iswas 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 goals,with respect to the succession and development actions and concluded that Mr. Brandt had successfully completed those actions, all as detailed further on page 65, are structuredpages 75-76 of this Proxy Statement. On February 19, 2019, the Committee approved a $4 million payment to incentivize continued financial performance while ensuring that succession- and development-related milestones are met. As discussed further below, for 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.

​EXECUTIVE COMPENSATION

Executive Compensation

Our Philosophy and Objectives

Our compensation program is designed to be transparent with a clear emphasis on putting pay at risk and retaining key executives. Our executive compensation philosophy incorporates the following core principles and objectives:

•
●Alignment with Shareholder Interests.Alignment with Shareholder Interests.We structure our annual cash and long-term equity incentive compensation to put pay at risk and reward business performance. Payouts under these plans are tied predominantly to the Company’s total return to shareholders, earnings, and the achievement of measurable and sustainable business and individual goals, so that executives’ interests are tied to the success of the Company and are aligned with those of our shareholders.
●Key Management Retention.We structure our program to provide compensation at levels necessary to attract, engage and retain an experienced management team who have the skill sets and industry experience to succeed in our complex operating and regulatory environment, including operating the Palo Verde Generating Station, and who can provide consistently strong operating and financial results.

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 rewardtied 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.

ROLE OF EXECUTIVE OFFICERS IN DETERMINING EXECUTIVE COMPENSATION

Management works with the Committee in establishing the agenda for Committee meetings and in preparing meeting information. 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 performance. Payouts under these plansunit 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 tied predominantlyavailable to the Company's total returnCommittee’s compensation consultant to shareholders, earnings,provide information as requested by the consultant.

ROLE OF COMPENSATION CONSULTANTS

The Committee’s charter gives the Committee the sole authority to retain and sustainable businessterminate any consulting firm used by the Committee in evaluating non-employee director and individual goals, so that executives' interests are tiedofficer compensation. 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 successCompany 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.

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. As part of this study, the Consultant performed competitive pay comparisons for our executive officers based on three data sets:

Peer Group (33%)(1)General Industry Data (33%)(1)Industry-Specific Data (33%)(1)
2017/2018 compensation information as disclosed in 2018 SEC filings for the Peer Group (as described below)Based on surveys published by Aon Hewitt (averaging data for companies in the $2.5B-$5B revenue and $5B-$10B revenue brackets) and Willis Towers Watson PLC (“Towers Watson”) (averaging data for companies in the $3B-$6B revenue and $6B-$10B revenue brackets)From the Towers Watson Energy Services Industry Survey (reflecting the average between companies in the $3B-$6B revenue bracket and companies with revenues greater than $6B)
(1)

Reflects weightings used for Messrs. Brandt, Guldner (for both roles in 2019), Hatfield, and Smith. Weightings for Messrs. Bement and Froetscher are discussed below.

From these sources, the Consultant developed a consensus in which the competitive industry comparison for Messrs. Brandt, Guldner, Hatfield, and Smith reflects a weighting of one-third peer group proxy statement data, one-third Energy Services Industry Survey, and one-third general industry surveys. Messrs. Bement and Froetscher did not have a general industry survey match, so the competitive industry comparisons reflect an average of the peer group proxy statement data and Energy Services Industry Survey data for each position. Compensation levels were updated to 2019 based on projected executive level market movement from major salary planning surveys selected by the Consultant.

EXECUTIVE COMPENSATION

In providing information to the Committee with respect to setting 2019 compensation, the Consultant reviewed the total compensation levels of the NEOs and presented its analysis in October 2018. At this time, the Consultant also reviewed the individual elements of compensation, including the design of annual incentives and long-term incentives. In December 2018 and again in October 2019 the Consultant provided additional analysis for Mr. Guldner to support his promotions to Executive Vice President, Public Policy of PNW, President of APS, and to Chairman of the Board, President, and Chief Executive Officer of PNW and Chairman of the Board and Chief Executive Officer of APS.

In its analysis, the Consultant provided competitive findings for base salary, annual incentive, long-term equity incentives and target total direct compensation for the NEOs relative to the 25th, 50th and 75th percentile (the October 2019 analysis for Mr. Guldner considered the 25th percentile to median). The conclusions of the reports as to competitive pay comparisons of the NEOs for these compensation elements are aligned with thoseas follows:

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 skill setsCommittee evaluates other factors that it considers relevant, such as the financial condition of the Company and industry experience to succeedAPS. 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.

EXECUTIVE COMPENSATION

DETERMINING THE PEER GROUP

The Peer Group (defined below) used as one input in our complex operatingpay comparison process is reviewed annually for its continued appropriateness. The Committee takes into consideration the scope and regulatory environment,complexity of the Company’s management responsibility and liability needs, including operating 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.

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 who can provide consistently strong operatingCholla 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 financial results.

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 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 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 between the 25th percentile and median with respect to revenues (adjusted as explained above).

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.

Base SalaryBASE 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 a peer groupthe 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.

Earnings Component Target Setting

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'tdon’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.

20172019 Earnings Goals.Goals
For fiscal year 2017,2019, the Committee set threshold, target and maximum Pinnacle West and APS earnings goals above prior year goals, however, as discussed previously,to reflect modest sales growth and continued focus on effective cost controls. We set the APS earnings target earnings were setat $538 million for 2019, relatively flat to achieved2018 actual incentive earnings for purposes of the 2017 Incentive Plans since at the time 2017 goals were$537.2 million. Likewise, we set the outcomePinnacle West’s 2019 target earnings range such that its projected midpoint was $515 million, compared to Pinnacle West’s 2018 actual incentive earnings of APS's rate review was still pending and the timing of the decision and magnitude of impact on Pinnacle West's revenues was as yet undetermined. As a result, fiscal 2017 earnings goals were set based on the expectation of earnings in the context of the business and economic conditions at that time, and did not take into account any projection of revenue and earnings in a new rate environment.$511 million.

The August 2017 approval of our comprehensive rate review is reflected in earnings goals set for 2018. Given the increase in revenues enabled by the rate adjustment, 2018 earnings goals represent meaningful year-over-year increases in the earnings metrics in our annual incentive plans.

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'sCompany’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.

●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 reviews and discusses the metrics and targets provided by the business units
●The Committee and the Board approves final metrics and targets

Under the business unit components of the 20172019 Incentive Plans, the range of potential achievement for each business unit metric was zero to 200% of the target level. In addition toWithin that range, a target level some of the performance measures alsoachievement provided for a 100% payout, a threshold level (equal toprovided for a 50% of target)target payout and a maximum level (equal toprovided for a 200% of target).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.

20172019 Business Unit Goals.Goals
The 20172019 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,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'sCEO’s incentive to overall operational performance of the Company, and not to emphasize any one unit'sunit’s performance over the others. Other NEOs were evaluated based on performance in the business units that correlate to their responsibilities.

See "Business“Business Unit Components Under the 20172019 Incentive Plans"Plans” on page 5969 for additional details regarding the metrics, targets and 2017 achievement levels for each business unit. As discussed above, weWe have revised our 20182019 metrics in certain key business units to more closely align with our priorities and emphasize top quartile performance and/or improve on

2019 ANNUAL CASH INCENTIVE OUTCOMES
CEO Incentive Plan

Earnings Component.EARNINGS COMPONENT
For Mr. Brandt, the earnings portion of the annual cash incentive was determined based on PNWPinnacle West earnings. 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 impactseffect of the rate adjustmenttiming of an ACC decision related to the installation of the Four Corners selective catalytic reduction equipment deferrals and the impactrefund of excess deferred taxes related to the 2017 Tax Cuts and Job Act. The net effect of these adjustments was to reducea reduction in Pinnacle West earnings from $488.5 million$538.3 to $475.4 million.$508.4.

EXECUTIVE COMPENSATION

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. Beginning with the 2016 awards,For our CEO and our Executive Vice Presidents, our annual long-term equity awards have beenwere 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. For 2018, we have increased the grant allocation to 70% performance-based measures and 30% time-based vesting for our CEO and our Executive Vice Presidents.

Long-term incentives award mix changed to 70% performance share awards and 30% RSU awards starting in 2018 for the CEO and Executive Vice Presidents.

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'sCompany’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'sCompany’s common stock and then allocated the 20172019 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.RSUs for all other officers.

The 20172019 awards to the NEOs were as follows:

Performance Shares

PERFORMANCE SHARES
We granted performance shares to our NEOs in February 20172019 for a three-year performance period (the "2017“2019 Performance Shares"Shares”), with two distinct elements — relative TSR and relative operational performance against five metrics.

The Committee grants each award recipient a specified number of performance shares, which is considered the "Base“Base Grant."” Under each of the two performance elements, up to 100% of the Base Grant may be earned based on performance. The maximum award opportunity is 200% of the Base Grant, which reflects the sum of the maximum opportunities for performance against the two elements:

GRAPHICTSR

TSR.TSR is the measure of a company'scompany’s stock price appreciation plus dividends during the three-year performance period. 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 2020.2022. 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.Performance
The Company's "Average Performance"Company’s “average performance” with respect to the metrics listed below will be the average of the Company'sCompany’s percentile ranking for each of these metrics during each of the three years of the performance period:

For 2017 performance share awards, we determined not to use the J.D. Power Residential National Large Segment Survey benchmark as we had for prior awards. APS is undergoing an extensive technology upgrade to our customer service platform. This undertaking is focused on providing flexibility and scalability to respond to industry and customer demands. We believe that the J.D. Power benchmark is not an appropriate indicator of operational performance during this enterprise-wide project.

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 2020.2022.

The recipient must remain employed with the Company throughout the performance period, unless the recipient meets any of the exceptions described under "Potential“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 of the stock payout. This common stock is paid out only if the related common stock payout is made. The 20172019 Performance Shares are not included in calculating pension benefits.

The 20172019 Performance Shares are included in the Summary Compensation Table in the column under "Stock Awards"“Stock Awards” and in the Grants of Plan-Based Awards table.

Payouts of 20142016 Plan Awards.Awards
In 2014,2016, 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, 2016,2018, our TSR percentile was 84.2%64.7% compared to the companies in the Index. For the same period, our Average Performanceaverage performance percentile with respect to the 2016 performance metrics was 73.5%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 2017.2019. 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“Potential Payments upon Termination or Change of Control."

2017 CEO Performance-Contingent Award.Award
    As previously disclosed in advance of our 2017 Annual Meeting, inIn March 2017, the Committee granted the CEOMr. Brandt a two-year, performance-based cash award. This award iswas designed to incent Mr. Brandt, a retirement eligibleretirement-eligible CEO, to remain in his current role while further emphasizing the Board'sBoard’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'sCompany’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 iswas comprised of two tranches that arewere performance-conditioned on specific return on equity, earnings, and succession planning goals, with a maximum potential payout to Mr. Brandt of $4 million:

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“Discussion of Nonqualified Deferred Compensation."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.

Executive Compensation

Other Considerations
​

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 2017 Incentive Plans. 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.

Role of Executive Officers in Determining Executive Compensation.    Management works with the Committee in establishing the agenda for Committee meetings and in preparing meeting information. 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.

Role of Compensation Consultants.    The Committee's charter gives the Committee the sole authority to retain and terminate any consulting firm used by the Committee in evaluating non-employee director and officer compensation. The Committee engaged Frederick W. Cook & Co. to assist the Committee in its evaluation of 2017 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.

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.

Executive Compensation

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. As part of this study, the Consultant performed competitive pay comparisons for our executive officers based on three data sets:

GRAPHIC

(1)
Reflects weightings used for Messrs. Brandt, Hatfield, Falck, and Schiavoni. Weightings for Messrs. Bement and Edington are discussed below.

From these sources, the Consultant developed a consensus in which the competitive industry comparison for Messrs. Brandt, Hatfield, Falck, and Schiavoni reflects a weighting of one third peer group proxy statement data, one third Energy Services Industry Survey, and one third general industry surveys. Messrs. Bement and Edington did not have a general industry survey match, so the competitive industry comparison for Mr. Bement's position reflects a 100% weighting of Energy Services Industry Survey data for Top Nuclear Executives and the competitive industry comparison for Mr. Edington's position reflects a 100% weighting of peer group proxy statement data. Compensation levels were updated to July 2017 based on projected executive level market movement from major salary planning surveys selected by the Consultant.

In providing information to the Committee with respect to setting 2017 compensation, the Consultant reviewed the total compensation of the NEOs and presented its analysis in October 2016. The Consultant also reviewed the individual elements of compensation, including the type of annual incentives and long-term incentives, and evaluated the competitiveness of the individual elements of compensation of each such officer based on the survey data discussed above.

In its analysis, the Consultant looked at competitive findings for base salary, annual incentive, long-term equity incentives and target total direct compensation for the NEOs as compared with the 25th, 50th and 75th percentile (compensation data was considered at the 25th, 50th or

Long-term incentive comparison excludes the special performance-linked award of RSUs that were granted to Mr. Brandt in December 2012 and certain arrangements for Messrs. Edington and Bement under the non-qualified deferred compensation plan as described later in this Proxy Statement.

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.    The Peer Group 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 $1B annual budget, employs one-third of APS employees, and is subject to comprehensive and complex nuclear and environmental regulation

o
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
​

70GRAPHIC |      2018 Proxy Statement

​

Table of Contents

​

Executive Compensation
​
•
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.

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 $5.2 billion compared to its reported twelve months ended June 30, 2016 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 complexity

•
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 2016 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 median with respect to revenues (adjusted as explained above).

As outlined previously, peer proxy data is only one third of the compensation information that is referenced for our NEOs (except for Messrs. Bement and Edington, where peer proxy statement data is weighted at 0% and 100%, respectively). For 2017, the Peer Group consisted of the following predominantly rate-regulated utilities (the "Peer Group"):

​

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.

Taxation Considerations Regarding Executive CompensationTAXATION CONSIDERATIONS REGARDING EXECUTIVE COMPENSATION

Pursuant to Section 162(m) of the Internal Revenue Code (the "Code"“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"“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. TheIn 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 believescontinues 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, because of current ambiguities regardinguntil the scope of this transition rule,regulations are final, no assurance can be given that compensation intended to satisfy the requirements for this transition rule will in fact be deductible.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'sCompany’s business needs.

(4)

​EXECUTIVE COMPENSATION

(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 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.

(3)

The amounts in this column reflect the aggregate grant date fair value of performance shares and RSUs computed in accordance with FASB ASC Topic 718.

(4)

This amount represents the 2019 Performance Shares described under “Executive Compensation Components — Long-Term Incentives — Performance Shares” in the CD&A. In accordance with FASB ASC Topic 718, 50% of the value is based on the probable outcome of the performance conditions as of the grant date using a Monte Carlo simulation model ($93.66), while the other 50% is based on the closing stock price on the date of grant ($90.65). 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 CompensationVice President Public Policy of Pinnacle West and he had a target award opportunity of up to 90% of his base salary.

    The 2016 performance shares have a performance period beginning on January 1, 2016 and ending on December 31, 2018; however, the payout, if any, will not be determined until February 2019 for the portion tied to TSR and October 2019 for the portion tied to the six operational performance metrics. These are the dates the Company anticipates that we will have the information necessary to determine whether, and to what extent, these metrics have been met.

This amount represents the performance shares issued in 2015. The performance period for these performance shares ended December 31, 2017; however, the payout was not determined until February 2018 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 2018, 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 2015 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 — 6,542; Mr. Hatfield — 1,115; Mr. Bement — 521; Mr. Edington — 892; Mr. Falck — 1,115; and

Retirement Plan and Supplemental Plan.RETIREMENT PLAN AND SUPPLEMENTAL PLAN

The Company'sCompany’s Retirement Plan is a tax-qualified, non-contributorynoncontributory retirement plan for salaried and hourly employees. The Supplemental Plan provides additional retirement benefits for key salaried employees in addition to thosebut does not duplicate benefits provided under the Retirement Plan. The Supplemental Plan pays only the difference between 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 andare paid from the benefit payable undergeneral assets of the Retirement Plan. As a result, an executive who participates in the Supplemental Plan does not receive duplicative benefits.Company.

Prior to April 1, 2003, benefits under the Retirement Plan and the Supplemental Plan (the "Traditional“Traditional Formula Benefit"Benefit”) accrued in accordance with a traditional retirement plan formula based on average annual compensation and years of service (the "Traditional Formula"“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:

●

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. 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 (the "Account Balance Benefit") to a retirement account balance formula (the "Account“Account Balance Formula"Formula”). As part of the modification, all then currentActive 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. Mr. Brandt'sMessrs. Brandt’s and Froetscher’s benefits are calculated under the combined Traditional Formula/Account Balance Formula. Messrs. Hatfield's, Bement's, Edington's, Falck'sGuldner’s, Hatfield’s, Bement’s, and Schiavoni'sSmith’s benefits are calculated under the Account Balance Formula. Mr. Edington's benefits under the Supplemental Plan are calculated in accordance with his employment agreements with the Company, which are described in the narrative disclosure accompanying the Summary Compensation Table and the Grants of Plan-Based Awards table.

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 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.

A participant's Traditional Formula Benefit under the Retirement Plan is a monthly benefit for life beginning at normal retirement age and is equal to the participant's average monthly compensation 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. A participant's Traditional Formula Benefit begins when the participant reaches age 65 with 5 years of service or age 60 with 33 years of service. The maximum Traditional Formula Benefit a participant may receive under both the Retirement Plan and the Supplemental Plan is a monthly benefit of 60% of the participant's average monthly compensation.

Under both the Supplemental Plan and the Retirement Plan, a participant may elect to begin receiving the Traditional Formula Benefit after attaining early retirement age, which is defined as age 55 with 10 years of service. The Traditional Formula Benefit of an individual who makes this election is reduced to reflect the early commencement of benefits. Under the Supplemental Plan, the reduction equals 3% per year for each year for which the individual receives benefits prior to normal retirement and under the Retirement Plan, if the individual has more than

20 years of service, the reduction equals 3% per year for each year for which the individual receives benefits prior to normal retirement, and if the individual has less than 20 years of service, the benefit is actuarially reduced for each year for which the individual receives benefits prior to normal retirement. Messrs. Brandt, Hatfield and Bement currently qualify for early retirement, but not normal retirement, under the Retirement Plan and the Supplemental Plan. Mr. Falck currently qualifies for normal retirement under the Retirement Plan and the Supplemental Plan. Mr. Schiavoni does not currently qualify for early or normal retirement under either the Supplemental Plan or the Retirement Plan.

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'sparticipant’s account.

DCP andAND 2005 Plan.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"“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"Benefit”), (4) on account of termination prior to retirement ("(“Termination Benefit"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.

​

On December 15, 2004, the Board authorized the adoption of a new nonqualified deferred compensation plan for post-2004 deferrals (the "2005 Plan"“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'sparticipant’s base salary and up to 100% of the participant'sparticipant’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'sdirector’s fees must be made prior to the calendar year in which such base salary or director'sdirector’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'sparticipant’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.

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 2017.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 agreed in Mr. Falck's offer letter to make a $350,000 discretionary credit award to Mr. Falck in 2009, pursuant to the 2005 Plan (the "Falck DCP Discretionary Credits"). The first $250,000 vested on July 29, 2014 and the remaining $100,000 vested on July 29, 2016. The discretionary credit award earns interest in accordance with the 2005 Plan.

The Edington DCP Discretionary Credits are described in the narrative disclosure accompanying the Summary Compensation Table and the Grants of Plan-Based Awards table.

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“2008 Bement DCP Discretionary Credits"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.

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"“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 ("Termination Plans").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'sCompany’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, 20172019 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, Edington, FalckFroetscher, and SchiavoniSmith 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'sexecutive’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. EdingtonBrandt who retired in March 2017)November 2019) had died on December 31, 2017,2019, the amounts payable under the Supplemental Plan, would have been as follows: Mr. BrandtGuldner — $11,379,622;$1,952,646; Mr. Hatfield — $2,662,223;$3,659,063; Mr. Bement — $2,056,350;$2,991,274; Mr. FalckFroetscher — $2,258,009;$5,363,844 and Mr. SchiavoniSmith — $2,379,438.$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'sNEO’s spouse for life following his death and benefit payments commence immediately and (2) the Account Balance BenefitFormula is paid in the form of an

The unvested 2014 Bement DCP Discretionary Credits would trigger a payment in connection with certain Termination Events, which are identified below. The agreement is discussed in the Discussion of Nonqualified Deferred Compensation.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'srecipient’s retirement while qualifying for Early Retirement or Normal Retirement (the "Retirement Qualified Employee") 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'srecipient’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“Late Career Employee"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'srecipient’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

In the event the recipient'srecipient’s employment is terminated without cause during the performance period, the CEO, in his discretion and with the Committee'sCommittee’s approval, may determine if, to what extent, and when, any unvested portion of the grant may vest. The 2017 Performance Sharesperformance 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. 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. 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'sCommittee’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'srecipient’s rights are adequately protected, a change of control will not result in any acceleration of a recipient'srecipient’s performance shares or RSUs. However, if a change of control occurs and the conditions of the following paragraph are not met, immediately prior to the change of control, the RSUs and performance shares will convert to either cash or stock, at the election of the recipient, and shall immediately vest. In converting the performance shares, the recipient will receive the number of shares of stock or the cash equivalent that would have been earned at the target level of performance, unless the Committee determines that a higher level of attained performance is reasonably ascertainable as of a specified date prior to the closing of the change of control transaction. The dividend equivalent awards will be paid in cash or stock as determined in accordance with the applicable award agreement.

Prior to a change of control, the Board may determine that no change of control shall be deemed to have occurred or that some or all of the enhancements to the rights of the recipient shall not apply to specified awards. The Board may exercise such override authority only if, before or immediately upon the occurrence of the specified event that would otherwise constitute a change of control, the Board reasonably concludes in good faith, that: (1) recipients holding awards affected by action of the Board override shallwill 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.

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"“double-trigger” that provides for certain payments if, during the two-year period following a change of control of the Company (the "first trigger"“first trigger”), the Company terminates the officer'sofficer’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'sexecutive’s employment (the "second trigger"“second trigger”). In case of an officer'sofficer’s retirement, death or disability, no payments are made under the officer'sofficer’s Change of Control Agreement, except for the payment of accrued benefits; however, if the officer dies following the officer'sofficer’s receipt of a second trigger termination notice, the officer'sofficer’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'sNEO’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'sexecutive’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-yearsfour 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. The executive officer may also be entitled to the acceleration of benefits as set forth in the 2012 Plan, the 2007 Long-Term Incentive Plan, or any related award agreement. 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.

A change of control under the Change of Control Agreement includes: (1) an unrelated third-party'sthird-party’s acquisition of 20% or more of the Company'sCompany’s or APS'sAPS’s voting stock; (2) a merger or consolidation where either the Company or APS combines with any other corporation such that the Company'sCompany’s or APS'sAPS’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“Company Incumbent Board"Board”) or of APS (the "APS“APS Incumbent Board"Board”), as of July 31, 2007 (and with respect to Messrs. Hatfield Falck, and SchiavoniGuldner as of July 31, 2008) no longer comprises at least two-thirds of the Company'sCompany’s or APS'sAPS’s Board of Directors. For purposes of this later provision, a person elected to either Board is treated as a member of the Company Incumbent Board or APS Incumbent Board if his or her nomination or election by shareholders was approved by a two-thirds vote of the members then comprising the Company Incumbent Board or APS Incumbent Board, and it does not include anyone who became a director in an actual or threatened election contest relating to the election of directors.

Each of the agreements terminates on December 31st31st 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.

Pay Ratio

Pay Ratio

As required by Item 402(u) of Regulation S-K, we are providing the annual disclosure of the ratio of the median employee'semployee’s annual total compensation to the prorated total annual compensation of Mr. Brandt, our former CEO and Mr. Guldner, our current CEO. For 20172019 the median of the annual total compensation of all employees of our Company (other than our CEO) was $128,140$132,212 and the prorated total annual total compensation of our former CEO and current CEO, as reported in the Summary Compensation Table in this Proxy Statement, was $10,533,439.$11,882,550. Based on this information and using the required calculation methodology defined in Item 402(u) of Regulation S-K,S–K, for 2017,2019, the ratio of the annual total compensation of our CEO to our median employee'semployee’s annual total compensation was 8290 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.
●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.

In accordance with FASB ASC Topic 718, this amount reflects the aggregate grant date fair value of the stock awards. On May 17, 2017, all of the directors at that time received a grant of either common stock or stock units ("SUs"), based on an election previously delivered to the Company. All directors received common stock except for Messrs. Fox and Gallagher, Drs. Herberger and Klein, and Ms. Munro, who each received SUs. Under the terms of the SUs, Dr. Klein will receive 100% of the SUs in cash and the other directors will receive 50% of the SUs in cash and 50% of the SUs in common stock on the last business day of the month following the month in which they separate from service on the Board. The number of shares of common stock or SUs granted was 1,311, and the grant date fair value of each share of common stock or SU is $84.10, which was the closing stock price on May 16, 2017. As of December 31, 2017, the following directors had the following outstanding RSU or SU awards: Mr. Fox — 2,820; Mr. Gallagher — 13,238; Dr. Herberger — 9,888; Dr. Klein — 13,289; and Ms. Munro — 11,244.

The Company does not have a pension plan for directors.

PROPOSAL 3
​ Ratification of The Appointment of Deloitte & Touche LLP as the Independent Accountant for the Company​​ The Board of Directors unanimously recommends a vote FOR ratification of the appointment of Deloitte & Touche LLP as the company’s independent accountant for the year ending December 31, 2020

Directors had an option to either receive the stock grant on May 17, 2017 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 or (2) 50% in stock and 50% in cash. The directors also elected whether to receive these payments either (1) as of the last business day of the month following the month in which the director separates from service on the Board, or (2) 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 SUs accrue dividend rights equal to the amount of dividends the director would have received if the director had directly owned one share of our common stock for each SU held, plus interest at the rate of 5% per annum, compounded quarterly. The manner of payment for the dividends and interest will be based on the director's election for payment of the SUs.

Directors of Pinnacle West also serve on the APS Board of Directors for no additional compensation. The Company reimburses Board members for expenses associated with Board meetings and director education programs.

The 2012 Plan was amended in 2017 to add an overall limit to non-employee directors' compensation. The value of equity grants (based 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 which 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. These changes will go into effect in May 2018. The Consultant reviewed the study, validated the methodology, and concluded that the new amounts were within the competitive range.

Directors' Compensation

​

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 January 2010, the Board adopted a revised stock ownership policy for non-management directors. Each director is required to hold or control Company common stock, RSUs, or SUs with a value of at least three times the annual cash retainer fee paid to directors. Directors will have until the later of January 2013 or three-years following the date they become a director to reach the required ownership level. A director may not pledge, margin, hypothecate, hedge, or otherwise grant an economic interest in any shares of Company stock while serving as a director whether or not his or her ownership requirement is met. This restriction shall extend 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. The Corporate Governance Committee may grant exceptions to this policy for hardship or other special circumstances.

All of the directors are in compliance with the Director Stock Ownership Policy.

Proposal 2 — Advisory Vote on 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;

•
The Company had a highly successful year in 2017, as discussed in the Proxy Statement Summary;

•
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.

Because your vote is advisory, it will not be binding upon the Human Resources Committee or the Board. However, we value our shareholders' opinions, and we will consider the outcome of the vote when determining future executive compensation arrangements.

Pre-Approval Policies

As part of its oversight responsibility with respect to the independent accountantsaccountant and in order to assure that the services provided by the independent accountantsaccountant do not impair the independent accountants'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 accountants'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 20172019 for the Company were pre-approved by either the Audit Committee or the Chair of the Audit Committee consistent with the pre-approval policy.

SHAREHOLDER PROPOSAL

PROPOSAL 4
Shareholder Proposal Seeking to Reduce Ownership Threshold to Call Special Shareholder MeetingsThe Board of Directors recommends a vote AGAINST this proposal

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.

2020 Proxy Statement107

Table of Contents

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.

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;
●Annual votes on the advisory “say-on-pay” vote on executive compensation;
●Proxy access, which is described on page 19;
●Cumulative voting for the election of directors; and
●No supermajority voting provisions.

In addition, Pinnacle Westregularly engages with shareholdersto 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 pages 35-36.

Moreover, a 15% threshold is also the same as, or lower than, the special meeting rights at 87% of 468 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 at the request of such a small minority of shareholders has the potential to injure the Company as they 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.

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 voteAGAINSTthis shareholder proposal.

GENERAL INFORMATION

Time, Date and Place

The Company’s 2020 Annual Meeting of Shareholders (“Annual Meeting”) will be held at 10:30 a.m., Mountain Standard Time, on Wednesday, May 20, 2020. The Annual Meeting will not be held at a physical location, but will instead be held virtually, where shareholders will participate by accessing a website using the Internet. The Annual Meeting will be accessed at www.virtualshareholdermeeting.com/PNW. To participate in the Annual Meeting, you will need the 16-digit control number included on the proxy card, the Internet Notice or the voting instruction form. Online check-in will begin at 10:15 a.m. Mountain Standard Time, and you should allow ample time for the online check-in proceedings. We will have technicians standing by ready to assist you with any technical difficulties you may have accessing the virtual meeting. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call: 855-449-0991. An audio broadcast of the Annual Meeting will be available by telephone toll-free at 877-328-2502 (domestic) or 412-317-5419 (international). Upon dialing in, you will need to provide your 16-digit control number. Depending on concerns about the Coronavirus or COVID-19, we may need to postpone the meeting. The Company would publicly announce a determination to postpone the meeting in a press release available atwww.pinnaclewest.comas soon as practicable before the meeting.

We continue to believe that the virtual-only format is in the best interests of our shareholders, given the time and expense of an in-person meeting compared to the shareholder participation at those meetings. The number of non-employee shareholders actually attending our Annual Meetings of Shareholders had significantly dwindled before we converted to the virtual only format. For the past five in-person meetings, only about 30 shareholders attended each of the meetings. The meetings, on average, lasted less than 45 minutes, including the formal business portion of the meeting, the remarks by the CEO, a video highlighting the Company’s performance, and the question and answer period. A virtual meeting allows all of our shareholders, regardless of location, the ability to participate in the Annual Meeting.

Our virtual meeting will be governed by our Rules of Conduct, which we use for both in-person and virtual meetings. Shareholders at the virtual-only meeting will have the same rights as at an in-person meeting, including the rights to vote and ask questions through the virtual meeting platform. In the event we are not able to answer all the questions that are asked during the meeting, a list of all questions asked that comply with the Rules of Conduct that were not responded to during the meeting, and our response, will be posted on our website shortly after the meeting. Given the concerns about Coronavirus, or COVID-19, we may alter the agenda of the 2020 Annual Meeting to accommodate the safety of our employees who work to make the Annual Meeting possible.

GENERAL INFORMATION

Quorum

The presence, in person or by proxy, of a majority of the outstanding shares of our common stock is necessary to constitute a quorum at the Annual Meeting. 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. Shares owned by the Company are not considered outstanding or present at the meeting.

Vote Required

Election of 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.

Say-on-Pay Vote

The votes cast “for” must exceed the votes cast “against” to approve the advisory resolution on the compensation disclosed in this Proxy Statement of our NEOs identified on page 49 — the say-on-pay vote. 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.

Ratification of the Appointment of the Independent Accountant and Approval of the Shareholder Proposal

The votes cast “for” must exceed the votes cast “against” to ratify the appointment of the independent accountant for the year ending December 31, 2020 and for the approval of the shareholder proposal. Abstentions and broker non-votes will have no effect on the outcome of either item. Because your vote is advisory, it will not be binding on the Board or the Company. However, the Board will review the voting results and take into consideration our shareholders’ views.

If any other matters properly come before the meeting, the proxy holders will vote on those matters in accordance with the recommendations of the Board or, if no recommendations are given, in accordance with their own judgment. The shareholder proposal will be voted on only if properly presented at the meeting.

OTHER MATTERS

Related Party Transactions

The Corporate Governance Committee is responsible for reviewing and approving all transactions with any related party, which consists of any of our directors, director nominees, executive officers, shareholders owning more than 5% of the Company’s common stock and, with respect to each of them, their immediate family members and certain entities in which they are an officer or a shareholder, partner, member or other participant who, directly or indirectly, has a substantial ownership interest in or otherwise substantially controls or shares control of such entity (a “Related Party”). 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 2019.

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. Because the amounts paid to Insight were such a small portion of its total revenues, the Corporate Governance Committee has determined that these payments are not material to Ms. Bryan.
