The dollar amounts reported in column (c) represent the amount of “compensation actually paid” to Mr. Guldner, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Guldner during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Mr. Guldner’s total compensation for each year to determine the compensation actually paid:

Cumulative TSR, as required by Item 402(v) of Regulation S-K, is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.

(6)

Cumulative peer group TSR, as required by Item 402(v) of Regulation S-K, is calculated using the same methodology used in calculating the Company’s cumulative TSR. Further, in calculating the peer group cumulative TSR, the returns of each component issuer is weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: Edison Electric Institute Index.

(7)

The dollar amounts reported represent the amount of net income reflected in PNW’s audited financial statements for the applicable year.

(8)

Adjusted APS earnings (“APS Adjusted Earnings”) is APS earnings calculated in accordance with GAAP, as adjusted for purposes of the annual incentive plans, as follows: for the APS 2020 Annual Incentive Award Plan and the APS 2020 Annual Incentive Award Plan for Palo Verde Employees, APS earnings were adjusted from $568.0 million to $587.7 million due to an accrual for the Coal Communities Transition Plan that was required under the accounting rules but that related to a future expense; for the APS 2021 Annual Incentive Award Plan and the APS 2021 Annual Incentive Award Plan for Palo Verde Employees, APS earnings were not adjusted; and for the APS 2022 Annual Incentive Award Plan and the APS 2022 Annual Incentive Award Plan for Palo Verde Employees, APS earnings were not adjusted.

Compensation Actually Paid vs. Total Shareholder Return [Text Block]
Compensation Actually Paid and Cumulative TSR

As demonstrated by the following graph, the amount of compensation actually paid to Mr. Guldner and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Guldner) is generally in line with the cumulative TSR except in the case of the 2021 TSR, which was advsersely impacted by the 2019 rate case decision. As discussed in the CD&A, a significant portion of our executive compensation program is equity based. The Company does not use cumulative TSR in its executive compensation program, but does use relative TSR in the performance share grants as discussed in more detail in the CD&A. TSR impacts our compensation program in two ways — the actual stock price increases and decreases impacts the value of the equity awards and the relative TSR performance metric drives whether a significant portion of the overall equity grant pays out and to what degree.

  
   
Compensation Actually Paid vs. Net Income [Text Block]
Compensation Actually Paid and Net Income

As demonstrated by the following table, the amount of compensation actually paid to Mr. Guldner and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Guldner) as compared to net income is reflective of continued strong sales growth over the three year period. The decline in net income in 2022 is primarily due to no longer deferring costs relating to our Four Corners power plant selective catalytic reduction equipment and the Ocotillo power plant modernization project as a result of the unfavorable 2019 rate case decision.

Although we don’t use net income in our executive compensation program, we do use earnings in the 2022 Incentive Plans, as discussed below.

Compensation Actually Paid and APS Adjusted Earnings

As demonstrated by the following graph, the amount of compensation actually paid to Mr. Guldner and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Guldner) is generally in line with APS earnings, with 2022 earnings reflective of the decrease in APS rates as a result of the 2019 rate case. APS Adjusted Earnings is used in the 2022 Incentive Plans and represents 50% of the payout opportunity under those plans. Although Mr. Guldner’s payout opportunity is tied to Pinnacle West earnings, APS earnings account for a significant portion of Pinnacle West earnings, and is therefore a significant part of Mr. Guldner’s opportunity.

 
   
Total Shareholder Return Vs Peer Group [Text Block]
Cumulative TSR of the Company and Cumulative TSR of the Peer Group

As demonstrated by the following graph, the Company’s cumulative TSR over the three-year period presented in the table was 8%, while the cumulative TSR of the peer group presented for this purpose, the Edison Electric Institute Index, was 17% over the three years presented in the table. Pinnacle West’s TSR underperformed compared to the Edison Electric Institute primarily due to a pending rate case in 2020 and 2021, which ended unfavorably for the Company, and investor concerns over the regulatory climate in Arizona. For more information regarding the Company’s performance and the companies that the Human Resources Committee considers when determining compensation, refer to the CD&A.

Financial Performance Measures

As described in greater detail in the CD&A, the Company’s executive compensation program is designed to be transparent with a clear emphasis on putting pay at risk and retaining key executives. The metrics that the Company uses for both our long-term and short-term incentive awards emphasize putting pay at risk and aligning our executives interests with those of our shareholders. The most important performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows:

APS Adjusted Earnings

Relative TSR

Stock price

Capital spend

Operations and maintenance spend

Customer satisfaction

Safety
