  27. Board Committees

    The Board regularly reviews director compensation with the assistance of Meridian Compensation Partners (the same consultant used for executive compensation) to determine whether it is appropriate and competitive in light of market circumstances and prevailing best practices for corporate governance for the energy/utility industry. The Board targets overall director compensation to the median of the same peer group used to review executive compensation. (See “Competitive Analysis and Peer Group” in the Compensation Discussion and Analysis.) As a result of this review process, the annual retainer for directors was increased from $220,000 to $225,000 effective September 1, 2023. The additional retainer for the chair of the Compensation Committee increased from $15,000 to $17,500 effective September 1, 2023. The elements of director compensation reflect the Board’s view that compensation to the independent directors should consist of an appropriate mix of cash and stock. The cash portion of the retainer is paid quarterly, and the stock portion is paid annually (as soon as practicable following the Annual Meeting). Employee directors are not compensated for their Board service.

  59. ROLE OF THE COMPENSATION CONSULTANT

    ROLE OF THE COMPENSATION CONSULTANT The Compensation Committee selects and retains an independent compensation consultant to support its oversight of our executive compensation programs. For 2023, the Compensation Committee engaged Meridian Compensation Partners (“Meridian”) as its independent compensation consultant. (The Committee also purchased survey information from the Willis Towers Watson (“WTW”) Energy Services Executive Compensation database but did not otherwise consult with WTW.) Meridian provides the Compensation Committee consulting services solely relating to executive compensation and related governance matters. In accordance with NYSE rules, the Compensation Committee determined Meridian is independent and, further, no conflicts of interest arose due to Meridian’s services rendered to the Compensation Committee. A representative of Meridian attended Compensation Committee meetings in 2023 and advised the Compensation Committee on the principal aspects of executive compensation, including the competitiveness of program design and award values and specific analyses for our executive officers. The Compensation Committee determines the work to be performed by Meridian. Meridian works with our Senior Vice President of Safety & Chief People Officer and his staff to gather data required in preparing its analyses for Compensation Committee review. Meridian provides services or advice to management only to the extent requested by the Compensation Committee. Meridian interacts with management to gather information and obtain recommendations, but the Compensation Committee Chair determines if and when Meridian’s advice and materials can be shared with management. When important pay decisions are made, Meridian provides advice to the Compensation Committee in an executive session without Company management present. This approach ensures the Compensation Committee receives objective advice from Meridian so the Compensation Committee can make independent decisions about executive pay.

    | • | The Compensation Committee reviews both short-term and long-term financial scenarios to ensure the plan design does not encourage executives to take excessive risks but also does not discourage appropriate risks; |

  64. COMPENSATION PHILOSOPHY AND OBJECTIVES

    COMPENSATION PHILOSOPHY AND OBJECTIVES Our executive compensation program is designed to align executive pay with our financial and operational performance and the creation of long-term value for our shareholders. To accomplish these objectives, our compensation program incents executive officers to achieve specific annual, long-term, and strategic goals and improves shareholder value. The Compensation Committee believes the overall compensation of our senior executives should be weighted toward variable performance-based compensation. As a result, a significant portion of compensation is linked with goals related to specific items of corporate performance likely to produce long-term shareholder and customer value. The charts below show the portion of target compensation that is variable and, therefore, is “at risk” for our CEO and the average for our other NEOs. Variable compensation includes annual incentives, RSUs and performance shares. The charts also show the portion of target compensation for our CEO and the average target compensation for our other NEOs directly linked to share value, including RSUs and performance shares.

  65. COMPETITIVE ANALYSIS AND PEER GROUP

    COMPETITIVE ANALYSIS AND PEER GROUP The Compensation Committee believes it is important to provide a compensation structure competitive with compensation paid to comparable executives of companies within the energy/utility industry to ensure the Company can attract and retain quality employees in key positions to lead the Company. To achieve this objective, the Compensation Committee works with Meridian to conduct an annual competitive review of its total compensation program for our CEO and other NEOs. Through the review process, the Compensation Committee generally targets overall total compensation levels (base, short-term incentive and long-term incentives) at the median of the peer group. Pay components for an individual NEO may be higher or lower than the median depending on an individual’s role, responsibilities, and performance within the Company. The Compensation Committee believes this target positioning is effective to attract and retain our executives. The Compensation Committee annually compares each element of NEO total compensation against a peer group of publicly traded companies within the energy/utility industry of similar revenue size and market capitalization. For 2023, our NEO compensation was compared with market data, as disclosed in proxy statements, from the sixteen companies in the S&P 400 Mid-Cap Utilities Index (“Proxy Peer Group”). This group is designed to be representative of the Company’s business, size and competitive market for talent. The use of publicly disclosed data allows the Company to maintain a consistent peer group. The Proxy Peer Group can change slightly from year to year due to changes in company size and weightings determined by S&P. Hawaiian Electric was removed and Vistra Corp was added in 2023. The companies comprising the 2023 Proxy Peer Group were:

  66. COMPETITIVE ANALYSIS AND PEER GROUP

    | ALLETE, Inc. | New Jersey Resources Corporation | Portland General Electric Co. | | Black Hills Corporation | NorthWestern Corporation | PNM Resources, Inc. | | Essential Utilities, Inc. | OGE Energy Corp | Southwest Gas Holdings, Inc. | | IDACORP, Inc. | ONE Gas, Inc. | Spire Inc. | | National Fuel Gas Company | Ormat Technologies, Inc. | UGI Corporation | | | | Vistra Corp. |

  67. COMPETITIVE ANALYSIS AND PEER GROUP

    To supplement market data derived from the Proxy Peer Group, the Compensation Committee also considered benchmark compensation data derived from the WTW Energy Services Executive Compensation database, which covered comparable diversified energy companies with revenues between $1 billion and $3 billion and with median revenues of $1.62 billion. This supplemental compensation data helped to inform the Compensation Committee on broad market compensation practices and trends within the energy services sector.

  68. LONG-TERM EQUITY COMPENSATION

    LONG-TERM EQUITY COMPENSATION The Compensation Committee believes equity-based compensation is the most effective way to create a long-term link between shareholder returns and the compensation provided to NEOs and other key management. This program encourages participants to focus on long-term Company performance and provides an opportunity for executive officers and designated key employees to increase their ownership in the Company through grants of Company stock that can be earned based on either service or performance, over a three-year cycle. Using long-term performance awards and time-based restricted stock (RSUs), the Company can compensate executives for sustained increases in the Company’s stock performance, as well as long-term growth relative to its peer group for the relevant cycle. The Company’s current Long-Term Incentive Plan (“LTIP”) authorizes various types of equity awards. As with all the components of executive compensation, the Compensation Committee determines all material aspects of the long-term incentive awards—who receives an award, the form of the award, the amount of the award, the timing of the award, as well as any other aspect of the award it may deem material. For 2023 equity grants, the Compensation Committee determined each NEO’s target LTIP value based on competitive market data and the NEO’s ability to influence overall Company performance. In addition, and as previously discussed, the Compensation Committee targets overall total compensation levels, which include base salaries, short-term incentives and long-term incentives, at the median of the Proxy Peer Group. The Compensation Committee determined 70% of the NEO’s target LTIP value would be granted in the form of performance share units (“PSUs”) and 30% of the NEO’s target LTIP value would be granted in the form of RSUs; this was updated from 2022 when the allocation mix was 75% and 25%, respectively. Awards are generally granted each year at the February Compensation Committee meeting and the granting of awards is not coordinated with the release of material non-public information.

  69. Performance-Based Equity Awards

    Performance-Based Equity Awards In February 2023, the Compensation Committee approved the grant of PSUs to each NEO. The 2023 PSUs are designed to provide a direct link to the long-term interests of shareholders by ensuring shares will be paid only if the Company attains specified performance levels. For 2023, 17.5% of the awards were contingent on our Total Shareholder Return (TSR) relative to our peers and 52.5% was measured by our Cumulative Earnings Per Share (CEPS) over a three-year period. For 2023, the Compensation Committee considered market data provided by Meridian regarding the total compensation levels for our CEO and all other NEOs compared to the median of the Proxy Peer Group. The peer group for TSR performance purposes consists of the sixteen companies comprising the S&P 400 Mid-Cap Utilities Index as of January 1 in the first year of the three-year performance cycle. Throughout the course of the performance cycle, companies may be added or dropped from the index by S&P due to mergers or other activities. At the end of the cycle, new companies added to the index are included in the rankings as if they had been in the ranking from the beginning, provided there is sufficient trading history to include them in the final calculation. When a company is dropped from the index, everything related to the company is excluded as if it were never in the index.

  70. Performance-Based Equity Awards

    | 2024 PROXY STATEMENT | 37 |

  71. Performance-Based Equity Awards

    The number of PSUs which vest is determined at the end of the three-year performance cycle based on the Company’s percentile rate-of-return ranking compared to the companies in the S&P 400 Mid-Cap Utilities Index, and is payable at the Compensation Committee’s discretion in cash, shares of Company common stock, or a combination of both. Dividend equivalents on performance awards are accumulated and paid upon vesting if the awards vest and are paid based on performance. If the Company’s relative TSR over the three-year performance period is below the threshold performance required to earn the award, accumulated dividends are forfeited as well. The second performance metric, Cumulative Earnings Per Share (CEPS), aligns with current competitive practices within the peer group based on market data provided by the Compensation Committee’s consultant. Each year the Compensation Committee reviews and establishes a threshold, target, and maximum performance level for CEPS. The Compensation Committee seeks to establish performance levels that assure the goals are realistic enough to be achievable yet difficult enough to incentivize outstanding performance. The amount of payment of any award is determined at the end of the three-year performance cycle based on the Company’s earnings and is payable at the Compensation Committee’s discretion in cash, shares of Company common stock, or a combination of both. Dividend equivalents on performance awards are accumulated and paid upon vesting if the awards vest and are paid based on performance. If the Company’s CEPS over the three-year performance period is below the threshold performance required to earn the award, accumulated dividends are forfeited as well.

  72. Range of Award Opportunity for Performance Share Units

    Range of Award Opportunity for Performance Share Units Each year, the Compensation Committee approves a grant to each NEO of a target number of performance share units that vest over a three-year performance cycle based on achieving pre-determined performance goals. The number of performance shares that may be earned at the end of the performance cycle can range from 0% to 200% of the target, depending upon the level of achieved performance. The target number of performance share units granted to each NEO was determined by dividing the NEO’s target LTIP value allocated to performance share units by the grant date share price of our common stock. The table below shows the changes made to the target value of performance share grants in 2023 for the 2023 through 2025 performance period for our NEOs. In general, the target value of performance shares aligns with market data for 2023, considering the allocation of PSUs changed from 75% in 2022 to 70% in 2023. Mr. Christie received additional grants in May 2023, valued as of the grant date, upon his promotion to CFO. Mr. Manuel joined the company in 2023.

  78. 2021-2023 Performance Shares Settlement

    2021-2023 Performance Shares Settlement For performance shares linked to the Company’s TSR and granted in 2021 for the performance period ending December 31, 2023, the Compensation Committee held a special meeting on January 9, 2024, to review, certify, and settle the issuance of shares to executive officers. The Company’s cumulative TSR was 3.36% during the three-year performance cycle, which placed the Company at the 39th percentile among the S&P 400 Mid-Cap Utilities Index. Based on these results, our CEO and our other NEOs earned 72.5% of the performance share awards granted in 2021 vesting based on TSR. Accrued cash dividend equivalents were paid out on the same percentage of performance shares covered by the 2021 grant. For performance shares linked to the Company’s Cumulative Earnings Per Share (CEPS) and granted in 2021 for the performance period ending December 31, 2023, the Compensation Committee reviewed, certified and settled the issuance of shares to executive officers at its February 2023 meeting. The Company’s CEPS for the 2021-2023 performance cycle ended at $6.46. Based on these results, our CEO and our other NEOs earned 53% of the performance share awards granted in 2021 vesting based on CEPS, noting that Mr. Manuel did not receive this grant, as he joined the Company in 2023. Accrued cash dividend equivalents were paid out on the same percentage of performance shares covered by the 2021 grant.

  82. Restricted Stock Units (RSUs)

    Restricted Stock Units (RSUs) In February 2023, the Compensation Committee approved the grant of RSUs to each NEO. The 2023 RSUs are designed to incent retention, link compensation to the value of the Company common stock and align the interests of our NEOs with those of our shareholders. The 2023 RSUs are subject to three-year ratable vesting. On each vesting date one-third of the RSUs are settled in shares, provided the NEO remains continuously employed by the Company through the vesting date. Dividend equivalents on RSUs accrue and are paid in cash to the extent the underlying RSUs vest. To the extent RSUs are forfeited, the accrued dividend equivalents on such RSUs also would be forfeited. The number of RSUs granted to each NEO was determined by dividing the NEO’s target LTIP value allocated to RSUs by the grant date share price of our common stock. The table below shows the changes made to the target value of RSU grants in 2023 for the 2023 through 2025 vesting period for our NEOs. As with performance share units, in general, the target value of RSUs increased to align with market data for 2023. Mr. Christie and Ms. Rosentrater received the highest increases to bring their respective target values closer to market in their new roles.

  88. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS The Compensation Committee believes it is in the interest of shareholders to provide severance to our executive officers in the event of a CIC, thereby reducing the inherent conflict of our executive officers pursuing a transaction that may result in their personal job loss. Effective January 1, 2020, our new Executive Change in Control Plan (“CIC Plan”) was put in place for all executive officers of the Company replacing individual agreements certain executive officers had regarding a CIC. The following are key features of the plan:

  89. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    | • | Severance multiple: NEOs prior to January 1, 2020 would receive three times the sum of the executive’s annual base salary and target annual bonus. Future NEOs and other officers would receive two times the sum of the executive’s annual base salary and target annual bonus. |

  90. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    | 2024 PROXY STATEMENT | 41 |

  91. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    | • | Severance also includes reimbursement of 18 months of COBRA premiums, if COBRA is elected by the individual. |

  92. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    | • | Payment of severance is conditioned on the individual’s delivery of a release of claims. |

  93. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    | • | “Good reason” includes material diminution of authority, responsibility, pay, bonus opportunity or budget overseen, material relocation or material breach by the Company of the plan. |

  94. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    | • | Certain protections, such as a minimum annual base salary, provided to executive officers during continued employment for up to two years following CIC. |

  95. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    | • | No 280G excise tax gross up; CIC benefits are limited to greater of, on an after-tax basis, the full amount of CIC benefits subject to excise tax or a reduced amount equal to the maximum amount of CIC benefits that could be paid without triggering the 280G excise tax. |

  96. CHANGE IN CONTROL (“CIC”) AND SEVERANCE BENEFITS

    Additional information regarding the CIC Plan, including definitions of certain key terms and a quantification of benefits that hypothetically would have been received by our NEOs under the CIC Plan, and an applicable termination occurred on December 31, 2023, due to a CIC can be found in the Potential Payment Upon Termination or CIC Tables.

  99. Summary Compensation Table — 2023

    | 1. | Amounts earned in the applicable year; includes regular pay, paid time-off, jury duty and holiday pay. The total amounts shown in this column also include any amounts an NEO elected to defer in accordance with the EDC Plan. See the “Non-Qualified Deferred Compensation Plan” table for more information. |

  100. Summary Compensation Table — 2023

    | 2. | Values shown represent the aggregate grant date fair value calculated in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718 “Compensation—Stock Compensation” for RSUs and performance share awards granted in each of the years reported. Assumptions used in the calculation of these amounts are included in Note 1 of the Company’s audited financial statements for the year ended December 31, 2023, included in the Company’s Annual Report on Form 10-K filed with the SEC. In the case of performance share awards tied to TSR, the amounts reported in the Stock Awards column represent the aggregate grant date fair value of the target number of performance shares that may become vested if the applicable performance criteria are satisfied and computed in accordance with ASC 718. The aggregate grant date fair value for the target number of performance shares was calculated by using a Monte Carlo simulation, which produces a probable value for the awards. All performance share awards vest at the end of the vesting term, however the number of shares delivered vary based upon the attained level of performance and may range from 0 to 2.0 times the target number of performance shares awarded. For the 2023 performance share grant, if the maximum level of performance is achieved and using the closing stock price of $35.74 as reported on December 29, 2023, to calculate the value and add the dividend equivalents using an annual amount of $1.84 per share as declared in 2023 multiplied by three years, then the value of the payouts would be: Mr. Vermillion $3,680,887; Mr. Thies $860,106; Mr. Christie $749,117; Ms. Rosentrater $756,873; Mr. Thackston $564,272; and Mr. Manuel $297,650. |

    | 4. | Any increase in the present value of the accrued pension benefit at normal retirement age (the earliest age at which retirement benefits may be received by the NEO without any reduction in benefits) for any NEO between December 31, 2022, and December 31, 2023, is reported in this column. All NEOs experienced an increase in the present value of their respective accrued pension benefits during 2023. The present value as of December 31, 2023, utilizes the Pri-2012 mortality table with modified MP-2021 generational projection for males and females and a 5.86% discount rate for the retirement plan and a 5.95% discount rate for the SERP. Differences in the present value from year to year are attributable to increases in final average pay, additional service, discount rates fluctuations and mortality assumptions. There were no above-market earnings for the Company’s EDC Plan. Mr. Manuel is included in the company’s 401(k) plan only based upon his hire date. |

  104. Summary Compensation Table — 2023

    | 5. | Includes employer matching contributions under both the EDC Plan and the Investment and Employee Stock Ownership Plan (the “401(k) plan”). The Company makes matching contributions on behalf of all its employees who make regular contributions of their wages, salary, cash incentive, and overtime to the 401(k) plan during the plan year. The Company matching contribution to the 401(k) plan is equal to $0.75 for every $1.00 of regular employee contributions up to a maximum 6% of compensation for non-employees hired prior to January 1, 2006. For non-bargaining employees hired after that date, the Company matching contribution is equal to $1.00 for every $1.00 of regular employee contributions up to a maximum of 6% of compensation. for those non-bargaining employees hired after January 1 2014, there is an additional enhanced contribution of 3/4/5% based on age. The Company matching contribution under the EDC Plan is equal to $0.75 for every $1.00 contributed up to a maximum of 6% of the executive’s base pay less the maximum contribution allowed under the 401(k) plan assuming the participant contributed the maximum allowed by law. Amounts shown in the All Other Compensation column for 2023 include the following: |

  108. CEO PAY RATIO

    CEO PAY RATIO The Compensation Committee reviewed a comparison of CEO total compensation to the total compensation of the median employee. The compensation for the CEO in 2023 was approximately 27 times the total compensation of our median employee. In 2023, we identified the median employee by first collecting pay records on all employees from all companies within the corporation including subsidiaries, 1,988 (full-time, part-time, seasonal, and temporary), who were employed by us on December 22, 2023. To determine our median employee, we used a definition that was not annual total compensation, as shown in the 2023 Summary Compensation Table above, and instead chose “base pay rate,” which we then annualized as if all employees worked full-time and were employed for all of 2023. We identified 237 employees whose annualized base pay was within a +/-5% range of the median annualized base pay rate. Total cash compensation from 2023 was collected for each of the 237 employees to further narrow down the population. We believe the use of total cash compensation for this group of employees is a consistently applied compensation measure because we do not widely distribute annual equity awards to employees. Fewer than 3% of our employees receive annual equity awards. We calculated annual total compensation for the employee using the same methodology we use for our NEOs as set forth in the 2023 Summary Compensation Table above. The annual total compensation for 2023 was $5,229,962 for our CEO and $196,535 for our median employee. The resulting ratio of our CEO’s pay to the pay of our median employee for 2023 is 27 to 1. The foregoing pay ratio disclosure, including but not limited to any assumptions, adjustments, methodologies and existing internal records used to identify our median employee, is a reasonable estimate calculated in a manner consistent with SEC Item 402(u) of Regulation S-K. The SEC rules for identifying the median employee and calculating that employee’s annual total compensation allow companies to make reasonable assumptions and estimates, and to apply a variety of methodologies and exclusions reflecting their compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different compensation practices, and may utilize different assumptions, estimates, methodologies and exclusions in calculating their own pay ratios.

  123. Grants of Plan-Based Awards — 2023

    | 3. | Performance share awards are granted under the LTIP and vest over a three-year period. The number of shares earned at the end of the three-year performance period depends on the level of performance achieved. See the CD&A for further explanation. |

  124. Grants of Plan-Based Awards — 2023

    | 4. | In 2023, all of our NEOs were awarded RSUs under the LTIP that vest over a three-year period. One-third of the shares vest and shares are issued on an annual basis, provided that the NEO is employed on the last day of the vesting period. Dividend equivalents accrue on the unvested RSUs and are paid in cash at the same time the underlying RSUs vest. Therefore, if an NEO’s employment ends prior to the last day of the vesting period, no RSUs or dividend equivalents are earned or paid. |

  125. Grants of Plan-Based Awards — 2023

    | 5. | The amounts shown for the grant date fair value of the target number of performance share awards tied to TSR were calculated in accordance with ASC 718.

  145. Pension Benefits — 2023

    Pension Benefits — 2023 The table below reflects benefits accrued under the Retirement Plan for Employees and the two SERPs (for purposes of the discussion below, we refer to both the pre-2005 SERP and the post-2004 SERP as the “SERP”) for our NEOs. The Company’s Retirement Plan for Employees provides a retirement benefit based upon employees’ compensation and years of credited service. The retirement benefit under the Retirement Plan is based on a participant’s final average annual base salary for the highest 36 consecutive months during the last 120 months of service with the Company. Base salary for our NEOs is the amount under “Salary” in the Summary Compensation Table. The SERP provides additional pension benefits to executive officers of the Company, who have attained the age of 55 and a minimum of 15 years of vesting service with the Company. The SERP is intended to provide benefits to executive officers whose pension benefits under the Company’s Retirement Plan are reduced due to the application of limitations on qualified plans under the Code and the deferral of salary pursuant to the EDC Plan. When combined with the Retirement Plan, the SERP will provide benefits to executive officers, other than our CEO, who retire at age 62 or older, of 2.5% of the final average annual base salary during the highest 60 consecutive months during the last 120 months of service for each credited year of service up to 30 years. When combined with the Retirement Plan, the SERP will provide higher benefits to our CEO, if he retires on or after age 65, of 3% of final average base salary during the highest 60 consecutive months during the last 120 months of service for each credited year of service up to 30 years. Benefits will be reduced for executives who retire before age 62. Reductions are either 4% or 5% for each year of retirement before age 62 as prescribed in the Retirement Plan.

    | 1. | Eligible employees may elect to defer up to 75% of their base annual salary and up to 100% of their annual bonus. This column represents deferrals of this compensation during the last year. See the Summary Compensation Table for further explanation. |

  155. Non-Qualified Deferred Compensation Plan — 2023

    | 2. | The Company matching contribution under the EDC Plan is equal to $0.75 for every $1.00 contributed up to a maximum of 6% of the executive’s base pay less the maximum contribution allowed under the 401(k) plan assuming the participant contributed up to the limit set forth in Code Section 402(g) for the plan year. See “All Other Compensation” column of the Summary Compensation Table for further explanation. |

  156. Non-Qualified Deferred Compensation Plan — 2023

    | 3. | Earnings reflect the market returns of the NEO’s investment allocations. The earnings accrued for deferred compensation are determined by actual earnings of Avista common stock and selected mutual funds. None of the earnings are included as compensation on the Summary Compensation Table since none are above market earnings. The Compensation Committee selects the mutual funds available for investment under the EDC Plan, and the participants may allocate their accounts among these investments, including Avista common stock. |

  157. Potential Payment Upon Termination or Change in Control (“CIC”)

    Potential Payment Upon Termination or Change in Control (“CIC”) Effective January 1, 2020, the Company’s new CIC Plan covers all NEOs and replaced individual CIC agreements in effect on December 31, 2019 for our NEOs who had such agreements. Under the new CIC Plan, the cash component is paid in a lump sum and is based on a multiple of the sum of base salary and annual bonus. No participant in the CIC Plan is eligible to receive cash severance in excess of the sum of (i) pro-rated annual bonus plus (ii) a multiple greater than three times base salary and annual bonus. The CIC Plan has a double trigger providing for a severance payment only upon the occurrence of both a CIC and a termination of the NEO’s employment within two years thereafter either by the Company without “Cause” or by the NEO for “Good Reason” (each as defined in the CIC Plan). Good Reason with a material diminution in the executive officer’s authority, duties or responsibilities material diminution in the executive’s annual salary or bonus opportunity, or material relocation of the executive officer’s principal place of employment by more than 50 miles. The CIC Plan also provides compensation and benefits to our NEOs during employment following a CIC of the Company. Pursuant to the terms of the CIC Plan, during the two years following a CIC of the Company, an NEO will receive an annual base salary no less than as in effect immediately prior to the CIC. In addition, each NEO will receive an annual bonus no less than the NEO’s target annual bonus as in effect immediately prior to the CIC. If employment is terminated by the Company without Cause or by such executive officer for Good Reason during the first two years after a CIC, the executive officer will receive: (i) the earned but unpaid base salary due to such executive officer as of the date of termination; (ii) any earned but unpaid annual bonus; (iii) any accrued, unused vacation pay; (iv) a pro-rated target annual bonus due to such executive officer for the portion of the year worked prior to the termination; (v) a lump sum payment equal to two or three times (depending on the officer’s level) the sum of the NEO’s annual base salary and the target annual bonus; and (vi) reimbursement of COBRA continuation coverage premiums for up to 18 months. For Code Sections 280G and 4999 and excise taxes thereunder, the CIC Plan provides no gross up for such taxes. The CIC Plan provides that the NEO will receive the greater of, on an after-tax basis, the full amount of CIC benefits subject to the excise tax or a reduced amount equal to the maximum amount of CIC benefits that could be paid without triggering the 280G excise tax. The excise tax amount in the tables below is based on the Company’s estimate of the individual’s liabilities under Code Sections 280G and 4999, assuming the NEO was terminated in connection with a CIC on December 31, 2023. The Board may amend or terminate the CIC Plan at any time, provided any amendment or termination will not take effect for 12 months following the date of such Board action. The Board may not, prior to a CIC, amend the Plan in a manner adversely affecting any participant’s eligibility to participate in the CIC Plan or payments or benefits thereunder. If employment terminates for any reason other than for retirement, death or disability during a performance cycle, all performance-based awards are forfeited. If employment terminates due to retirement, death or disability, the payment amount is still determined at

    the end of the three-year performance cycle and is prorated based on the number of months of active service during the cycle. If employment terminates in connection with a CIC, RSUs are fully accelerated and performance shares have prorated acceleration based on target performance. Participation in the CIC Plan is subject to various conditions including, but not limited to: (i) agreement to maintain confidence as to participation in the Plan and terms of the Plan, as well as the Company’s business plans and strategies and other information that is not common knowledge, (ii) a general release of liability for any and all claims relating to or arising out of, among other things, the participant’s employment or the termination of employment and (iii) a general non-disparagement agreement. The charts below assume a CIC occurred and a termination thereafter occurred on December 31, 2023.

  203. Potential Payment Upon Termination or Change in Control (“CIC”)

    PROPOSAL 3: ADVISORY VOTE ON EXECUTIVE COMPENSATION Proposal 3: Advisory Vote on Executive Compensation

  204. Potential Payment Upon Termination or Change in Control (“CIC”)

    | What are you voting on? | Shareholders are being asked to approve, on an advisory basis, the compensation of the Company’s NEOs. | | Voting Recommendation: | The Board unanimously recommends a vote FOR this proposal and urges beneficial owners, if they are not the record holders, to instruct their brokers or other nominees to vote for Proposal 3. |

  205. Potential Payment Upon Termination or Change in Control (“CIC”)

    As required by the Exchange Act, the Board is submitting a separate resolution, to be voted on by shareholders in a non-binding vote, approving, on an advisory basis, the Company’s executive compensation. The text of the resolution in respect of this Proposal 3 is as follows: “Resolved, that the shareholders approve, on an advisory basis, the compensation of the Company’s NEOs as disclosed in the Company’s proxy statement, pursuant to the compensation disclosure rules of the SEC, under the “CD&A,” “Executive Compensation Tables” and the related narrative disclosure.” The Board recommends a vote for this resolution. As described in this proxy statement under the CD&A, the Company’s compensation program is designed to focus Company executives on the achievement of specific annual, long-term and strategic goals set by the Company. The goals are structured to align executives’ interests with those of shareholders by rewarding performance that maintains and improves shareholder value. The following features of the compensation structure reflect this approach:

  206. Potential Payment Upon Termination or Change in Control (“CIC”)

    | • | Executive compensation programs have both short and long-term components. |

  207. Potential Payment Upon Termination or Change in Control (“CIC”)

    | • | Annual cash incentive components focus on both the actual results and the sustainability and quality of those results. |

  208. Potential Payment Upon Termination or Change in Control (“CIC”)

    | • | The total compensation program does not provide for guaranteed bonuses and has multiple performance measures. |

  209. Potential Payment Upon Termination or Change in Control (“CIC”)

    | • | The Company has a recoupment policy that authorizes the Board to recover incentive payouts based on performance results that are subsequently revised or restated to levels that would have produced payouts lower than the original incentive plan payouts. The recoupment policy includes up to three years of incentive compensation if an officer engages in detrimental conduct. |

  210. Potential Payment Upon Termination or Change in Control (“CIC”)

    | • | The CIC Plan, effective January 1, 2020, replaced individual CIC agreements for current officers who had such agreements and the tax gross-up provision was removed. |

  211. Potential Payment Upon Termination or Change in Control (“CIC”)

    The Board believes the Company’s current executive compensation program properly focuses our executives on the achievement of specific annual, long-term and strategic goals. The Board also believes the Company’s executive compensation program properly aligns the executives’ interests with those of shareholders. Shareholders are urged to read the CD&A section of this proxy statement, which discusses in greater detail how the Company’s compensation program implements the specific goals set by the Company.

  212. Potential Payment Upon Termination or Change in Control (“CIC”)

    | | The Board recommends a vote “FOR” the approval, on an advisory basis, of the compensation of the Company’s NEOs. |

  213. Potential Payment Upon Termination or Change in Control (“CIC”)

    Although the advisory vote on Proposal 3 is non-binding, the Board and the Compensation Committee will review the results of the vote and, consistent with our record of shareholder engagement, are expected to take the outcome of the vote into consideration, along with other relevant factors, in determining future executive compensation and the frequency of such advisory votes.

  215. Potential Payment Upon Termination or Change in Control (“CIC”)

    The following table shows the number of shares of common stock of the Company held beneficially, as of March 1, 2024, by (i) each director and nominee, (ii) each of our NEOs in the Summary Compensation Table, (iii) all current directors and executive officers as a group and (iv) each person who is known to the Company to be the beneficial owner of more than 5% of our common stock. No director or executive officer owns in excess of 1% of the stock of any indirect subsidiaries of the Company. None of the directors or NEOs has pledged Company common stock as security. As of March 1, 2024, there were 78,186,011 shares of common stock outstanding. Beneficial ownership, as shown below under the heading “Shares Beneficially Owned,” was determined in accordance with Rule 13d-3 under the Exchange Act. Under this rule, certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire shares (for example, upon the exercise of an option or warrant or the vesting of an equity award) within 60 days of the date as of which the information is provided. Shares shown under the heading “Other” are not considered beneficially owned in accordance with Rule 13d-3 but are considered by the Company in determining whether an individual has met the Company’s share ownership guidelines. In computing the percentage ownership of any person, the number of shares is deemed to include the number of shares beneficially owned by such person by reason of such acquisition rights. As a result, the percentage of outstanding shares of any person as shown in the table may not necessarily reflect the person’s actual voting power at any particular date. To our knowledge, except as indicated in footnotes to the table, the persons named in the table have sole voting and investment power for all shares of common stock shown as beneficially owned by them.
