Pay vs Performance Disclosure |  |  |  |  |  |
Pay vs Performance Disclosure, Table |  |  | PAY-VERSUS-PERFORMANCE As required by Item 402(v) of Regulation S-K, we are providing the following information regarding the relationship between executive compensation and our financial performance for each of the last three completed calendar years for our principal executive officer (“PEO”) and our Named Executive Officers other than our PEO (“Non-PEO NEOs”). In determining the “compensation actually paid” to our Non-PEO NEOs, we are required to make various adjustments to amounts that have been previously reported in the Summary Compensation Table in previous years, as the SEC’s valuation methods for this section differ from those required in the Summary Compensation Table. The table below summarizes compensation values both previously reported in our Summary Compensation Table, as well as the adjusted values required in this section for the 2023, 2022 and 2021 calendar years. Note that for our Non-PEO NEOs, compensation is reported as an average.
• | In 2023, the Non-PEO NEOs were Messrs. Wood, Patel, Collins, Manning, and Hottinger.
• | In 2022, the Non-PEO NEOs were Messrs. Patel, Collins, Hottinger, and Rose.
• | In 2021, the Non-PEO NEOs were Messrs. Patel, Hottinger, Jeff Krantz and Ken Stacherski.
• | In 2020, the Non-PEO NEOs were Mr. Krantz and Ms. Charlotte MacVane.

1. | Mr. Fusaro served as our PEO during 2021, and he resigned from the Company on April 18, 2022. On that same date, Mr. Hostetler was appointed as our PEO and continues to serve in such capacity.
2. | In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments in the table below were made to Mr. Fusaro’s and Mr. Hostetler’s total compensation for each year as reported in the Summary Compensation Table to determine the compensation actually paid. The valuation assumptions used to calculate the fair values of RSUs and PSUs include the stock price as of the applicable measuring date and, in the case of PSUs, the probable outcome of the performance conditions as of the applicable measuring date. Otherwise, the valuation assumptions used to calculate fair values did not materially differ from those used in our disclosures of fair value as of the grant date.
In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments in the table below were made to the NEOs’ average total compensation for each year to determine the compensation actually paid. The equity award adjustments for each applicable year include the same methodology described above for Messrs. Fusaro and Hostetler.

3. | The values disclosed in this column represent the measurement period value of an investment of $100 in our common stock as of October 15, 2020, the first date on which our common stock traded on the Nasdaq Global Market, and then valued again on each of December 31, 2023, 2022, 2021 and 2020.
4. | Represents the weighted peer group total shareholder return, 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 customized peer group used by the Company for purposes of Item 201(e) of Regulation S-K (Enphase Energy, Solaredge Technologies, Shoals Technologies Group and FTC Solar). For last year, the Company used the Russell 2000 Index as its peer group for this purpose. The Company has changed its peer group used for this purpose as a result of SEC guidance indicating that broad-based equity indices should not be used. The peer group TSR under SEC rules for the Russell 2000 index would be $115.10 for the period ending December 31, 2023, $79.60 for the period ending December 31, 2022, $149.80 for the period ending December 31, 2021 and $119.96 for the period ending December 31, 2020.

Compensation Actually Paid vs. Total Shareholder Return |  |  | Relationship between Compensation Actually Paid and Performance Measures Over the course of 2022, the Company’s net income rose $43.6 million, and revenue increased $781 million. In turn, total shareholder return increased over 200%. In 2023 while net income rose significantly, revenue dropped by 4%. As a result, total shareholder return was reduced as well. Compensation Actually Paid to Mr. Hostetler reduced in 2023, primarily driven by the loss in total shareholder return. Compensation Actually Paid to the NEOs excluding Mr. Hostetler likewise reduced in 2023, primarily driven by the loss in total shareholder return. Array’s compensation philosophy ties executive compensation and company performance through each pay element. Compensation actually paid to our NEOs was reduced in 2023, due to the loss of value in both outstanding equity awards granted but not vested, as well as vested equity awards. While shareholder return is directly tied to Array’s long-term incentive awards, individual performance is a strong determining factor for base salary actions and short-term cash incentives reflect collective team performance, as stated above. The chart below shows the correlation between total shareholder return and compensation actually paid for NEOs at Array. There is a clear and immediate relationship between the financial performance of the business and the pay for executive leaders. |  |  |
