    Advanced Energy’s Environmental, Social, and Governance Initiatives We incorporate environmental, social, and governance (“ESG”) responsibility across our business with the same focus and dedication as we approach all our initiatives. Sustainability is key to our strategy in the products we make, the way we operate, and how we govern as a public company. We believe that our efforts to increase power conversion efficiency and to improve the efficiency of and reduce waste in our operations reflect our commitment to minimizing the environmental impact and carbon emissions that may be linked to the industries we serve. We also aspire to be a premier employer and good corporate citizen and invest in diversity, inclusion, and social responsibility. We recognize that diverse perspectives and collaboration enable us to drive innovation and future growth for our global customers. Our results and ongoing efforts related to ESG are an integral part of our commitment to deliver long-term value to our global stakeholders. This commitment is driven from the highest levels of the Company, including our Chief Executive Officer, executive management team, and Board of Directors. In 2020, we added oversight of the Company’s sustainability program to the Nominating, Governance & Sustainability Committee. As indicated in its charter, the Nominating, Governance & Sustainability Committee is directed to review the Company’s progress towards achieving its sustainability goals, as well as to review ESG trends that could impact the Company’s operations, performance, and reputation. In 2022, we enhanced our ESG governance structure by launching our ESG steering committee and ESG working group. The ESG steering committee is responsible for providing management-level guidance on our ESG approach, while the ESG working group reports to the steering committee and is responsible for the implementation of ESG initiatives that advance our ESG program. We are excited to share certain of our “value driven” ESG initiatives, areas of focus, and accomplishments on the following page.

    | | Environment | | Social & Community | | Energy-Efficient Products. Advanced Energy’s dedicated R&D teams strive to improve power conversion efficiency, balanced with exceptional stability and nimble control and response. Every increase in power conversion efficiency reduces our customers’ power consumption, decreasing their environmental impact and carbon emissions. Advanced Energy’s innovations reduce electricity consumption in a wide range of industries, including semiconductor manufacturing, industrial and medical equipment, as well as data center computing, telecom, and networking. Energy-Efficient Operations. Advanced Energy makes continuous improvements to reduce our energy usage in our global factories. For example, our Philippines factory is a three-time Philippine Economic Zone Authority (PEZA) Hall of Fame Awardee for Outstanding Environmental Performance. By employing novel alternatives, the site reduces the need for thermal testing. We also track our greenhouse gas emissions at several key manufacturing sites. Reducing Waste. Advanced Energy strives to reduce waste and conserve natural resources through efficiency improvements and recycling. Our manufacturing facilities in Asia actively manage and maximize our waste diversion rate, and we have implemented water treatment and wastewater recycling programs. In addition, we are implementing a recycled packaging initiative to reuse packaging material for supplies from our local suppliers. | | Charitable Contributions. Our charitable contributions committee, founded in 2010, is supported and led by our employees. The committee provides financial support for 501(c)(3) corporations, nonprofit institutions, and organizations that improve education, the environment and health and social services across the communities in which we operate and where our employees live. Diversity and Inclusion. We have approximately 10,000 employees located across the globe. Each person’s background and unique skill set are fundamental to our success. The Corporate Diversity & Inclusion Steering Committee provides guidance and direction on diversity, equity, and inclusion while enabling local teams to develop specific, targeted initiatives as appropriate. We also have an active Women’s Leadership Forum focused on career development and internal networking. Volunteerism. We offer each employee eight hours of paid time off to volunteer with self-selected 501(c)(3) organizations or other nonprofit organizations. Community Involvement. We work closely with community organizations, including supporting STEM education in local schools, working with universities around the world to facilitate their innovative research projects, participating in local chambers of commerce and partnering with local nonprofit organizations. Advanced Energy’s STEM Scholarship Program, launched in 2020, aims to develop emerging talent in STEM fields. We accept applications from undergraduate and post-graduate students attending leading institutions in the field of power technologies. | | | | Governance | | Ethical Business Practices | | Commitment. Advanced Energy is firmly committed to strong and effective corporate governance practices and accountability to our stockholders. Continuous Improvement. We routinely review our governance practices against evolving best practices and consider feedback and input from our stockholders. We encourage you to review our Board Governance Guidelines on our website at www.advancedenergy.com/ en-us/about/leadership. Core Values. At all levels of our organization, Advanced Energy delivers results by building a culture grounded in our Core Values: innovation, integrity, empowerment, partnership, accountability, and execution. Transparency. We are committed to transparency in all parts of our business to promote accountability, cultivate trust, and foster open communication. We believe that transparency leads to improvements to our processes and policies, and ultimately contributes to our success. | | Human Rights. Respecting the human rights of our employees and all those involved in our business operations is a core principle for Advanced Energy. Integrity at our Core, Advanced Energy’s Code of Ethical Conduct, specifically prohibits activities involving slave, forced, bonded, or indentured labor, and child labor, and we require our suppliers use no forced labor themselves or in their supply chains. Integrity at our Core can be viewed on our website at www.advancedenergy.com/en-us/about/environment-social-and-governance. Supply Chain. We are committed to responsible sourcing of the materials that make up our products. We annually request our suppliers to confirm that minerals originating within DRC +9 are conflict-free. Employee Training and Helplines. We actively communicate to our employees on ethical business practices and provide a 24-hour anonymous hotline to address ethics issues. | |

    Director Qualifications The Board respects its responsibility to provide oversight, counseling, and direction to the management of the Company in the interest and for the benefit of the stockholders. Accordingly, it seeks to be composed of directors with diverse skills, experience, qualifications, and characteristics. It is critical that directors understand the markets in which the Company operates, specifically the semiconductor capital equipment, industrial and medical, data center, and telecom markets. It is equally important that, collectively, the directors have experience in each of the primary aspects of our business, including engineering, research and development, finance and audit, product strategy and development, customer relations, supply chain management, and sales and marketing. The following are certain qualifications, experience, and skills for Board members that are important to the Company’s business and its future:

  56. To be held on April 25, 2024

    | | Directors who have served in senior leadership positions are important to the Company, as they bring experience and perspective in analyzing, shaping, and overseeing the execution of important operational and policy issues at a senior level. These directors’ insights and guidance and their ability to assess and respond to situations encountered in serving on our Board may be enhanced if their leadership experience has been developed at businesses or organizations that operated on a global scale, faced significant competition, and/or involved technology or other rapidly evolving business models. | | Senior Leadership Experience | | | | Directors who have served on other public company boards can offer advice and insights with regard to the dynamics and operation of a board of directors, the relations of a board to the chief executive officer and other management personnel, the importance of particular agenda and oversight matters, and oversight of a changing mix of strategic, operational, and compliance-related matters. | | Public Board Experience | | | | Because the Company is a global leader in innovative power solutions for the semiconductor, data center, telecom, and industrial and medical markets, experience in relevant technology is useful in understanding the Company’s research and development efforts, competing technologies, the various products and processes the Company develops, the manufacturing and assembly-and-test operations, and the market segments in which the Company competes. | | Industry & Technical Expertise | | | | Because the Company is a global organization with research and development, manufacturing, assembly and test facilities, and sales and other offices in many countries, directors with global expertise can provide a useful business and cultural perspective regarding many significant aspects of our business. | | Global Expertise | | | | Knowledge of financial markets, financing and funding operations, and accounting and financial reporting processes is important because it assists the directors in understanding, advising, and overseeing the Company’s capital structure, financing and investing activities, financial reporting, and internal control of such activities. | | Financial Expertise | |

    Independence The Board of Directors has determined that each of the nominees, other than Stephen D. Kelley (i.e., Grant H. Beard, Frederick A. Ball, Anne T. DelSanto, Tina M. Donikowski, Ronald C. Foster, Lanesha T. Minnix, David W. Reed, John A. Roush and Brian M. Shirley), is an “independent director” within the meaning of the Nasdaq Stock Market Rules. Under these rules, to be considered independent, the Board must affirmatively determine, among other things, that neither the director nor any immediate family member of the director has had any direct or indirect material relationship with the Company within the last three years. The Board of Directors has made an affirmative determination that none of the independent directors has had any relationship with Advanced Energy or with another director that would interfere with the exercise of his or her independent judgement in carrying out his or her responsibilities as a director. The independent directors, if all of them are elected at the 2024 Annual Meeting, will constitute a majority of the Board of Directors. There is no family relationship amongst any of the directors and executive officers of the Company. The Company’s executive officers serve at the discretion of the Board. Involvement in Certain Legal Proceedings During the past ten years none of the persons currently serving as executive officers and/or directors of the Company has been the subject matter of any of the following legal proceedings that are required to be disclosed pursuant to Item 401(f) of Regulation S-K, including: (a) any bankruptcy petition filed by or against any business of which such person was a general partner or executive officer either at the time of the bankruptcy or within two years prior to that time; (b) any criminal convictions; (c) any order, judgment, or decree permanently or temporarily enjoining, barring, suspending or otherwise limiting their involvement in any type of business, securities or banking activities; (d) any finding by a court, the Securities and Exchange Commission (the “SEC”) or the Commodities Futures Trading Commission to have violated a federal or state securities or commodities law, any law or regulation respecting financial institutions or insurance companies, or any law or regulation prohibiting mail or wire fraud; or (e) any sanction or order of any self-regulatory organization or registered entity or equivalent exchange, association or entity. Nor are any such legal proceedings believed to be contemplated by governmental authorities against any director or executive officer. Further, no executive officers, directors, beneficial owners of more than five percent of the Company’s stock, or any other actor mentioned in Item 103(c)(2) of Regulation S-K is a party adverse to the Company in a material proceeding or has a material interest adverse to the Company.

    Our Board has adopted a director resignation policy (the “Policy”), which is included in the Company’s Board Governance Guidelines. The Policy applies to uncontested elections of directors, in other words, an election of directors where the number of nominees for election does not exceed the number of directors to be elected. A copy of the Policy is available on the Company’s website at www.advancedenergy.com/en-us/about/leadership within the Company’s Board Governance Guidelines. Under the Policy, any nominee for director in an uncontested election who does not receive a majority vote “FOR” that director’s election to the Board relative to the number of votes cast with respect to that director’s election (excluding broker non-votes, abstentions, and failures to vote with respect to that director’s election) will promptly tender a written offer of resignation to the Board. The Policy provides that the Nominating, Governance & Sustainability Committee of the Board will promptly consider the director’s offer of resignation and make a recommendation to the Board. Pursuant to the Policy, the Board would then act on that recommendation within 90 days of receipt. When deciding what action to recommend or take regarding the director’s resignation, the Policy permits each of the Nominating, Governance & Sustainability Committee and the Board to consider any factors they deem relevant, including the best interests of the Company and its stockholders. Under Delaware law, a nominee who receives a plurality of the votes cast at the 2024 Annual Meeting will be elected as a director (subject to the Policy described above). The “plurality” standard means the nominees who receive the largest number of “FOR” votes cast are elected as directors of the Company. Thus, the number of shares not voted for the election of a nominee (and the number of “withhold” votes cast with respect to that nominee) will not affect the determination of whether that nominee has received the necessary votes for election under Delaware law. However, the number of “withhold” votes with respect to a nominee will affect whether or not our Policy will apply to that individual. If any nominee is unable or declines to serve, proxies will be voted for the balance of those named and for such person as shall be designated by the Board, on recommendation by the Nominating, Governance & Sustainability Committee, to replace any such nominee. However, the Board does not anticipate that this will occur. Stockholders do not have the right to cumulate their votes for the election of directors. Unless otherwise instructed, the proxy holders will vote the proxies received by them “FOR” each of the ten (10) nominees. Votes withheld from a nominee will be counted for purposes of determining whether a quorum is present, but will not be counted as an affirmative vote for such nominee. The Board of Directors recommends a vote “FOR” the election of each of the nominees named above.

    In February 2014, our Board of Directors adopted a Stock Ownership Policy that requires non-employee directors to own an amount of stock of the Company with a value equal to at least five times the annual retainer for Board service (exclusive of any compensation for committee service, meeting fees, leadership roles, etc.), based in each case, on the volume weighted average closing price of the Company’s stock for the two fiscal years as of December 31 of the applicable year and subject to the terms in the Stock Ownership Policy. The Stock Ownership Policy provides for a phase-in period over five years for each member to achieve the requisite ownership requirements.

  77. The Compensation Committee

    The Compensation Committee The Compensation Committee is responsible for establishing, implementing, and monitoring adherence with the Company’s compensation philosophy. Accordingly, the Compensation Committee strives to develop and maintain competitive, progressive programs that reward executives for continuous improvement in key financial metrics that drive Company performance and stockholder value. The Compensation Committee also recognizes the need for compensation programs to attract, retain, and motivate high caliber employees, foster teamwork, and maximize the long-term success of Advanced Energy by appropriately rewarding our executives for their achievements. The Compensation Committee evaluates risk and rewards associated with the Company’s overall compensation philosophy and structure. The Compensation Committee has the authority to engage independent advisors to assist it in making determinations with respect to the compensation of our executives and other employees. For the 2023 fiscal year, the Compensation Committee engaged Compensia, Inc. to conduct a competitive review of executive compensation and advise the Compensation Committee on other compensation related matters. Compensia has not provided any other services to the Company or the Compensation Committee and has not received compensation other than with respect to the services provided to the Compensation Committee. In connection with its engagement of Compensia, the Compensation Committee (a) evaluated Compensia’s independence from management including the independence of the individual representatives of Compensia who served as the Compensation Committee’s consultants, and (b) determined that Compensia is free of conflicts of interest and independent based on the Nasdaq Stock Market’s independence factors.

  78. Use of Market Data for Comparison Against Peer Companies

    Use of Market Data for Comparison Against Peer Companies One factor that the Compensation Committee considers when making compensation decisions is the compensation paid to executives of a peer group of companies. The Compensation Committee also considers other factors discussed below under the heading “Components of Executive Compensation.” Our compensation peer group consists of publicly traded companies of roughly similar size to Advanced Energy, all of which are from related industries, including the semiconductor and electronic equipment industries, and may compete with Advanced Energy for executive talent. Our criteria for selecting our peer group companies includes companies with revenue between 50% and 200% and market capitalization between 33% and 300% of Advanced Energy. The Compensation Committee reviews our peer companies annually to take into account the volatility and breadth of the industries in which Advanced Energy participates. While the Compensation Committee attempts to maintain consistency year to year, adjustments are made as needed. In consultation with Compensia, the Compensation Committee reviewed its list of peer companies in July 2022, to be used for a comparative review for 2023 compensation. As a result of this review, the Compensation Committee removed Azenta, Inc. (formerly Brooks Automation, Inc.), Curtiss-Wright Corp., MACOM Technology Solutions Holdings, Inc., Moog, Inc., Novanta, Inc., Rogers Corporation, Semtech Corp., SPX Technologies, and Wolfspeed Inc. due to revenues outside the selection criteria, acquisition activity, and less relevant business fits. To replace these companies and better align with the semiconductor industry, the Compensation Committee added Cirrus Logic, Inc., MaxLinear, Inc., Silicon Laboratories Inc., Synaptics Incorporated, and Ultra Clean Holdings, Inc. For 2023, the list of peer companies consists of the following 15 publicly traded companies.

We intended for the 2023 STI Plan to motivate our executive officers to achieve these financial performance goals and reward them for accomplishing these goals. For 2023, the Compensation Committee selected the following financial

    measures: revenue, weighted at 40%, non-GAAP operating income from continuing operations weighted at 40%, and adjusted cash flow, weighted at 20%. The Compensation Committee believes that these metrics help to drive balanced performance across the business and that non-GAAP metrics are better indicators of the operating performance of the Company. For further discussion and a reconciliation of these non-GAAP measures, see Appendix A to this proxy statement. To address ongoing volatility in the markets the Company serves, the 2023 STI Plan provided two six-month performance periods (January 1 - June 30 and July 1 - December 31) for each of the financial measures. Any bonus earned during either six-month performance period is not paid until after the end of the fiscal year. The Compensation Committee set each of our named executive officers’ annual full-year target bonus opportunity as a percentage of his or her base salary. Actual bonuses awarded to each of our named executive officers may range from 0% to 200% of target depending on actual company performance over the performance periods, as described below. For 2023 these annual full-year bonus targets were as follows:

The Compensation Committee established the performance goals for each metric in alignment with the Company’s annual operating plan, which contemplated the Company’s business objectives and anticipated market conditions.

  95. Results of the 2023 Short-Term Incentive Plan

    Results of the 2023 Short-Term Incentive Plan Based on the performance over both halves of the incentive period, our overall corporate achievement was 100.3% for 2023. As a result, the Company’s payouts under the 2023 Short-Term Incentive Plan were as follows:

  97. Results of the 2023 Short-Term Incentive Plan

    The 2023 STI Plan included a discretionary individual performance-based modifier ranging from 0% to 150% of the amounts otherwise earned based on corporate performance by the named executive officers. The modifier had a cap in which no executive could achieve greater than 200% of the target incentive. For fiscal year 2023, the Compensation Committee chose not to modify the 2023 bonus of any executive officer based on individual performance.

  98. 2024 Short-Term Incentive Plan

    2024 Short-Term Incentive Plan The Compensation Committee, in consultation with Compensia, maintained the 2024 Short-Term Incentive Plan largely as designed in 2023, including the right to use a discretionary individual performance-based modifier ranging from 0% to 150% for the named executive officers, and continuation of the cap in which no executive can achieve greater than 200% of the target incentive. The Compensation Committee also approved weighting the potential 2024 STI earned over the two six-month performance periods proportional to the 2024 annual operating plan where 40% of the incentive potential is calculated in the first half and 60% of the incentive potential is calculated in the second half, consistent with the timing of projected earnings. Each half will be a stand-alone performance period.

  99. Long-Term Incentive Plan Compensation

    Long-Term Incentive Plan Compensation We use stock awards to motivate and reward our executive officers, including our named executive officers, for long-term corporate performance and to align their interests with those of our stockholders. Consistent with market practice in companies of our size and in our industry, our long-term incentive program is comprised primarily of full-value equity vehicles, namely time-based and performance-based restricted stock units (“RSUs”). We award RSUs to provide a long-term, retentive element to the executive pay package. We also use performance-based RSUs (“performance stock units”) in the program to further enhance the alignment between pay and the long-term performance of our Company. In fiscal year 2023, we granted our executives, including our named executive officers, a mix of performance-based and time-based RSU awards, on an equally weighted basis, under the 2023 LTI Plan. The annual equity awards granted to our named executive officers under the 2023 LTI Plan were determined by our Compensation Committee after reviewing data from a competitive market analysis prepared by Compensia. In addition, our

    Compensation Committee considered the input of our CEO regarding the criticality of, individual performance of, and pay levels for his direct reports. During 2023 each of our named executive officers participated in the 2023 LTI Plan, pursuant to which we granted equity awards under the Company’s 2017 Omnibus Incentive Plan, as amended. For 2023, the Compensation Committee determined the following 2023 target dollar value for equity awards granted to each of our named executive officers:

  104. Long-Term Incentive Plan Compensation

    2023 LTI Plan targets are set at levels that the Compensation Committee deems to be sufficient to attract and retain highly talented executive officers capable of fulfilling the Company’s key objectives. In consultation with Compensia, the Compensation Committee reviewed the LTI Plan targets of the Company’s executive officers compared to the peer group and general market data, as well as named executive officer performance and execution, to determine a 2023 LTI Plan target award value. The Compensation Committee determined that each of the named executive officers listed above would receive (a) 50% of the 2023 LTI Plan award value in the form of time-based restricted stock units and (b) 50% of the LTI Plan award value in the form of performance stock units. We determined the number of time-based restricted stock units and performance stock units to be granted to each named executive officer by dividing each named executive officer’s target grant date value indicated above by the 30-day trailing average of the closing price of the Company’s common stock leading up to the grant date, which was March 1, 2023 for the named executive officers. Accordingly, these values differ from the grant date fair value amounts reported in the “Summary Compensation Table for 2023” below, which are reported in accordance with both SEC and accounting rules. Further details regarding the number of time-based restricted stock units and performance stock units that we granted to each of the named executive officers under the 2023 LTI Plan can be found in the “2023 Grants of Plan-Based Awards” table below. The grants of time-based restricted stock units in 2023 vest ratably over a three-year period with 1/3 vesting on each anniversary of the grant date. The Compensation Committee, in consultation with Compensia, kept the metrics for the achievement of the performance stock units granted as part of the 2023 LTI Plan largely unchanged from 2022. In 2023, the performance stock units were again based 70% on our relative total shareholder return (“rTSR”) performance compared to a benchmark performance of the S&P 1000, and 30% based on achievement of strategic goals. For 2023, the strategic goal relates to achievement of established levels of non-GAAP gross margin percentage measured over any four consecutive quarters in the three-year performance period. Amounts may be earned as performance occurs, but do not vest and are not issued until the end of the performance period. The Compensation Committee believes that these metrics again closely align management’s interests with stockholders and maintains a focus on achieving strategic objectives. With respect to the rTSR component, eligible participants have the opportunity to earn up to one-third of the performance stock units during each of the 12-month, 24-month, and 36-month measurement periods, respectively, based on our rTSR performance compared to the S&P 1000. Eligible participants also have the ability to earn any additional performance stock units not earned in the first two measurement periods based on financial performance of our rTSR ranking relative to the S&P 1000 during the 36-month performance period. As noted above, any earned performance stock units are not eligible to vest or be issued until the end of the 36-month performance period. The multi-year structure reflects the cyclical nature of the markets that the Company operates in and encourages performance each year, while the 36-month performance period reflects the long- term incentive structure of the plan. As of December 31, 2023, participants have banked and earned

As of December 31, 2023, participants have banked and earned 46.6% of the total shares granted at target based on rTSR performance in 2022 and 2023; provided however, these shares will not vest until the end of the three-year performance period. Consistent with the design of the 2023 LTI Plan, our Compensation Committee determined that if the performance results of the 36-month period, as applied to all of the rTSR performance stock units, exceeds the sum of the 12-month, 24-month, and 36-month performance periods, each as applied to one-third of the rTSR performance stock units, then the performance results for the 36-month performance period will be the rTSR achievement for all of the rTSR performance stock units (up to 200%).

    2021 Long-Term Incentive Plan In 2021, we awarded each of our named executive officers performance stock units under our 2021 Long-Term Incentive Plan (the “2021 LTI Plan”) that vest based on our achievement of performance metrics over a three-year performance period (2021-2023). Under the 2021 LTI Plan, the performance stock units would vest based on the achievement of rTSR performance relative to the S&P 1000 for the 12-month, 24-month, and 36-month measurement periods and achievement of the strategic objectives to increase our market share in specified areas and to develop and implement an ESG plan. Our Compensation Committee determined to base the performance outcome for the rTSR component of the 2021 LTI Plan on our 36-month rTSR performance relative to the S&P 1000, which was achieved at 78.3%, and determined that the strategic objectives were achieved at the 116.6% performance level, resulting in overall performance for the 2021 LTI Plan of 89.8% of target. We believe that disclosure of the specific strategic objectives and outcomes could cause competitive harm as such corporate goals and results are not publicly disclosed and are competitively sensitive. Similar to our other targets, the Compensation Committee set the strategic objectives at a rigorous level so as to be challenging, yet achievable.

  124. Change in Control and General Severance Agreements

    Change in Control and General Severance Agreements The Company entered into certain executive change in control and general severance agreements (the “agreements”) in 2018 with Mr. Oldham, in 2021 with Mr. Kelley and in 2022 with Ms. Vonne and Mr. Donaghey. The agreements provide each of the executive officers with severance payments and certain benefits in the event of a termination without cause (as defined in the agreements) at any time (known as the “General Severance Benefits”), or a termination without cause or for good reason (as defined in the agreements) following an actual, or during a pending, change in control (known as “CIC Benefits”). The Company provides CIC Benefits in order to keep management focused on the Company’s stated corporate objectives irrespective of whether the achievement of such objectives makes the Company attractive for acquisition, and to avoid the distraction and loss of key management that could occur in connection with a rumored or actual change in corporate control. The Company decided to also provide General Severance Benefits in these agreements after determining that such benefits were commonly provided by the Company’s peers. The Compensation Committee approved the terms and conditions of the agreements based on consideration of marketplace benchmark data and the Company’s retention objectives. Under these agreements, if the executive’s employment is terminated without cause (and not in connection with a change in control), then the General Severance Benefits provided to the executive are: (a) all then accrued compensation, (b) a lump sum payment equal to one times (1x) (or in the case of the Chief Executive Officer, one and a half times (1.5x)) the executive’s then current annual base salary, (c) continuation of insurance and other benefits for twelve (12) months following the date of termination, (d) an amount equal to the contributions that would have been made to the Company’s retirement plans on behalf of executive, if the executive had continued to be employed for twelve (12) months following the date of termination, and (e) reimbursement, up to $15,000, for outplacement services. Under these agreements, in the event of an executive’s termination without cause or for good reason within 12 months following an actual, or during a pending, change in control, the CIC Benefits provided to the executive are: (a) all then accrued compensation and a pro-rata portion of executive’s target bonus for the year in which the termination is effected, (b) a lump sum payment equal one and a half times (1.5x) the executive’s then current annual base salary and target bonus for the year in which the termination is effected (or in the case of the Chief Executive Officer, two times (2x) the then current annual base salary and target bonus amount), (c) continuation of insurance and other benefits for 18 months following the date of termination, (d) an amount equal to the contributions that would have been made to the Company’s retirement plans on behalf of executive, if the executive had continued to be employed for twelve (12) months following the date of termination, (e) reimbursement, up to $15,000, for outplacement services, and (f) full vesting and right to exercise all stock options, equity grants and other equity awards (at maximum) then held by the executive so terminated. The payment of the General Severance Benefits and CIC Benefits under these agreements are conditioned upon the executive’s execution of a release of claims against the Company. Compensation Risk Assessment In 2023, the Compensation Committee, with the assistance of our compensation consultant, Compensia, Inc., reviewed the formal risk assessment for all our incentive compensation programs that have material impact on our financial statements. In conducting such review, the Compensation Committee considered key information about each incentive compensation plan within our compensation program, including the number of participants, target annual awards, performance metrics, and design features. As a result of such review, the Compensation Committee determined that none of our incentive plans presents a material adverse risk to the financial statements of the Company.

    Equity Compensation Plan Information The Company currently maintains two equity compensation plans, each of which were approved by the Company’s stockholders: The Company’s Amended and Restated 2023 Omnibus Incentive Plan (the “2023 Omnibus Plan”) and the Employee Stock Purchase Plan (“ESPP”). The 2023 Omnibus Plan replaced and superseded the Company’s 2017 Omnibus Incentive Plan, as amended (the “Prior Plan”), which terminated on April 27, 2023, following stockholders’ approval of the 2023 Omnibus Plan. Although options remain outstanding under the Prior Plan, no shares are available for future equity grants. The following table sets forth the number of shares of common stock subject to outstanding options and other rights, the weighted-average exercise price of outstanding options, and the number of shares remaining available for future award grants as of December 31, 2023, in the equity compensation plans.

  149. Analysis of the Information Presented in the Pay Versus Performance Table

    performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the Pay Versus Performance table.

  150. Compensation Actually Paid and Cumulative TSR

    Compensation Actually Paid and Cumulative TSR The following graph illustrate the relationship between the amount of compensation actually paid to Mr. Kelley, the average amount of compensation actually paid to the Company’s named executive officers as a group (excluding Mr. Kelley), the Company’s total stockholder return, and the total stockholder return of the Dow Jones Electrical Components & Equipment Index over the four years presented in the table. We believe the “Compensation Actually Paid” in each of the years reported above and over the four-year cumulative period are reflective of the Compensation Committee’s emphasis on “pay-for-performance” as the “Compensation Actually Paid” fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against pre-established performance goals under our 2023 STI program and 2023 LTI Plans.

    Compensation Actually Paid and Net Income The following graph illustrate the relationship between the amount of compensation actually paid to Mr. Kelley, the average amount of compensation actually paid to the Company’s named executive officers as a group (excluding Mr. Kelley) and the Company’s net income over the four years presented in the table. While the Company does not use net income as a performance measure in the overall executive compensation program, the measure of net income is correlated with the measure Non-GAAP Operating Income which the Company does use for setting goals in the Company’s short-term incentive compensation program. As described in more detail in the section “Compensation Discussion and Analysis,” the Company targets that approximately 18% of the value of total compensation awarded to the named executive officers consists of amounts determined under the Company short-term incentive compensation program.

    Compensation Actually Paid and Revenue The following graph illustrates the relationship between the amount of compensation actually paid to Mr. Kelley, the average amount of compensation actually paid to the Company’s named executive officers as a group (excluding Mr. Kelley) and the Company’s revenue performance. While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that revenue is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation actually paid to the Company’s named executive officers, for the most recently completed fiscal year, to Company performance. As described in more detail in the section “Compensation Discussion and Analysis,” the Company targets that approximately 18% of the value of total compensation awarded to the named executive officers consists of amounts determined under the Company short-term incentive compensation program and approximately 60% of the value of total compensation awarded to the named executive officers is to be comprised of equity awards, including restricted stock and stock options.

    CEO Pay Ratio As required by SEC rules, we are providing the following information about the ratio of the median annual total compensation of our employees and the annual total compensation of Mr. Kelley, our President and Chief Executive Officer. For the year ended December 31, 2023:

  160. Compensation Actually Paid and Revenue

    | ● | the median of the annual total compensation of all employees of our Company was reasonably estimated to be $8,368. The median identified is an Engineer, Design, located in the Philippines. |

  161. Compensation Actually Paid and Revenue

    | ● | the annual total compensation of Mr. Kelley for 2023, calculated in accordance with the Summary Compensation Table rules, was $8,296,122. |

  162. Compensation Actually Paid and Revenue

    | ● | based on this information, the ratio of the annual total compensation of our chief executive officer to the median of the annual total compensation of all other employees is estimated to be 991 to 1. |

  163. Compensation Actually Paid and Revenue

    Excluding our CEO, we identified the median employee by examining the base salary for all individuals we employed on December 31, 2023, the last day of our payroll year. We included all our employees globally, whether full-time, part-time, or seasonal, including any interns, fixed term, or apprentice employees. We annualized the total actual base salary for any permanent employee that works full-time but was hired after January 1, 2023. For any employee that we paid in currency other than U.S. Dollars, we then applied the applicable foreign currency exchange rate as of December 31, 2023, to convert such employee’s total compensation into U.S. Dollars. Once we identified our median employee, we added together all of the elements of such employee’s compensation for 2023 in the same way that we calculate the annual total compensation of our named executive officers in the Summary Compensation Table. To calculate our ratio, we divided Mr. Kelley’s annual total compensation by the median employee’s annual total compensation.

    Certain Relationships and Related Transactions Policies and Procedures with Respect to Related Party Transactions The Board is committed to upholding the highest legal and ethical standards of conduct in fulfilling its responsibilities and recognizes that transactions with the Company involving related parties can present a heightened risk of potential or actual conflicts of interest. Accordingly, as a general matter, it is the policy of the Company to avoid related party transactions. Such policy is evidenced in the Board Governance Guidelines and committee charters referenced in this proxy statement and in Integrity at our Core, Advanced Energy’s Code of Ethical Conduct. The types of transactions covered by the policy are:

  167. Compensation Actually Paid and Revenue

    | ● | those transactions described under FASB ASC Topic 850 or required to be disclosed in the Company’s financial statements or periodic filings with the SEC under Item 404(a) of Regulation S-K; |

    | ● | business or personal relationships between Board members. |

  170. Compensation Actually Paid and Revenue

    Any related party transaction that does arise must be reviewed and approved by the Audit and Finance Committee. The Audit and Finance Committee, in determining whether to approve the transaction, reviews the facts and circumstances in respect of the transaction for conflicts of interest, including the extent of the Board member or officer’s interest in the transaction, any anticipated effect on the Board member’s or officer’s independent decision-making or judgment in respect to matters affecting the Company, whether the transaction is on terms no more favorable than terms generally available to an unaffiliated third party, any anticipated effect on a Board member’s ability to commit sufficient time and attention to the Board, and other standards deemed appropriate by the committee members in light of the particular transaction being reviewed. In addition, the Audit and Finance Committee is responsible for reviewing and investigating any matters pertaining to the integrity of management, including conflicts of interest and adherence to the Code of Ethical Conduct.

    Proposal No. 4 – Approval of Advanced Energy’s Second Amended and Restated Certificate of Incorporation to Provide Exculpation from PERSONAL Liability for Certain Officers as Permitted by Delaware Law and Make Certain Other Minor, Non-Substantive Updates

  174. Compensation Actually Paid and Revenue

    | What am I voting on and how should I vote? | You are being asked to vote on approval of Advanced Energy’s Second Amended and Restated Certificate of Incorporation that would, among other minor, non-substantive updates, provide exculpation from personal liability for certain of the Company’s officers, as permitted by 2022 amendments to the Delaware General Corporation Law. We believe this Second Amended and Restated Certificate of Incorporation is necessary in order to (i) continue to attract and retain experienced and qualified executives, as similar officer exculpation provisions have been or are likely to be adopted by our peers and others with whom we compete for talent, and (ii) reduce personal legal exposure and help curb corporate litigation and associated costs. This Second Amended and Restated Certificate of Incorporation would also more generally align the protections available to officers with those protections currently available to our directors. The Board of Directors therefore recommends you vote “FOR” the approval of the Second Amended and Restated Certificate of Incorporation. |

  175. Compensation Actually Paid and Revenue

    On February 8, 2024, the Board approved, subject to approval from our stockholders at the 2024 Annual Meeting, the Second Amended and Restated Certificate of Incorporation of Advanced Energy (the “Proposed Certificate”) to (i) limit the personal liability of the Company’s officers (“Officer Exculpation”) in light of recent amendments to the Delaware General Corporation Law (“DGCL”) and (ii) make certain other minor, non-substantive updates and improvements (the “Non-Substantive Revisions”). Officer Exculpation Recent amendments to the DGCL, effective August 2022, enabled Delaware corporations to exculpate officers from personal liability for breach of the fiduciary duty of care in certain limited circumstances, similar to the limitations on liability that have long been applicable to directors. After careful consideration, the Board believes that the Company’s Amended and Restated Certificate of Incorporation currently in effect should be updated to align with developing law and provide exculpation from personal liability to certain senior officers in specific circumstances, as permitted by the DGCL.

    | PRECISION | POWER | PERFORMANCE | 63 |

  177. Compensation Actually Paid and Revenue

    | 2024 ANNUAL | | | PROXY STATEMENT | |

  178. Compensation Actually Paid and Revenue

    The DGCL and the Proposed Certificate both permit exculpation from liability only for direct claims brought by stockholders, including class actions, for breach of the fiduciary duty of care. Neither the DGCL, nor the Proposed Certificate eliminate officers’ personal liability for (i) claims for breach of the fiduciary duty of care brought by the Company itself or for derivative claims brought by stockholders in Advanced Energy’s name, (ii) breaches of the duty of loyalty, (iii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, and (iv) any transactions from which the officer derived an improper personal benefit. The Board believes the Proposed Certificate’s provision of officer exculpation is in the Company’s and its stockholders’ interests for the following reasons:

  179. Compensation Actually Paid and Revenue

    | ● | In recent years, officers have increasingly been named as defendants in stockholder litigation for claims of breach of fiduciary duty, resulting in protracted litigation (and associated costs) that would have been quickly dismissed if brought against directors. The Board believes that the Proposed Certificate could help mitigate any potential future harm to the Company and stockholders from this trend by preventing prolonged or frivolous litigation that distracts officers from their primary responsibilities and reducing insurance costs associated with lawsuits. Additionally, as public companies increasingly adopt officer exculpation clauses, insurance companies may raise director and officer insurance premiums for corporations that do not adopt officer exculpation provisions in their governing documents. |

  180. Compensation Actually Paid and Revenue

    | ● | The Board also believes it is necessary to provide officers with protection from exposure to personal liability to the fullest extent permitted by the DGCL in order to attract and retain skilled officers, especially as more and more public companies adopt officer exculpation provisions. The Company also expects its peers to adopt exculpation clauses that limit the personal liability officers in their governing documents, and failing to provide for Officer Exculpation could result in impaired recruitment and retention. Qualified officer candidates might be deterred from serving a company who fails to adopt similar protections due to exposure to personal liability and the risk that substantial expense may be incurred in defending lawsuits, regardless of merit. |

  181. Compensation Actually Paid and Revenue

    | ● | Finally, Advanced Energy’s officers frequently must make time-sensitive business decisions that can create substantial risk of investigations or lawsuits seeking to impose personal liability on the basis of hindsight and regardless of merit. The Board believes that the Proposed Certificate, by limiting officers’ exposure to personal monetary liability, will empower officers to exercise their business judgment in furtherance of stockholder interests without the potential distraction of undue personal risk. Officer Exculpation will also more generally align the protections available to our directors with those available to our officers. |

  182. Compensation Actually Paid and Revenue

    The Proposed Certificate is not being proposed in response to any specific resignation, threat of resignation, or refusal to serve by any officer or as a result of any pending or threatened litigation. Non-Substantive Revisions The Proposed Certificate also includes other minor, non-substantive improvements and updates to the Company’s currently effective Amended and Restated Certificate of Incorporation, principally technical and conforming changes and modernizing updates, such as conforming language between sections of the Proposed Certificate and the Company’s Second Amended and Restated By-Laws and substituting gender neutral terms. These minor improvements and updates will not have a substantive impact on the rights of stockholders of the Company. Effect of Approval The foregoing description of the Proposed Certificate is qualified in its entirety by reference to, and should be read in conjunction with, the full text of the Proposed Certificate, which is set forth in the form of the Second Amended and Restated Certificate of Incorporation attached hereto as Appendix B to this proxy statement.

    your convenience, Appendix B is marked with additions indicated by bold, underlined text and deletions indicated by struck text. If the Proposed Certificate is approved by the Company’s stockholders, it will become effective upon the filing of the Second Amended and Restated Certificate of Incorporation with the Delaware Secretary of State. This filing is expected to occur shortly after the 2024 Annual Meeting. If the Proposed Certificate is not approved by the Company’s stockholders, the Company’s Amended and Restated Certificate of Incorporation will not be amended and restated, and no exculpation from personal liability will be provided for the Company’s officers. The Company’s officers will nevertheless retain their rights under any indemnification agreements and insurance policies. Required Vote Approval of the Proposed Certificate requires the affirmative “FOR” vote of sixty-six and two-thirds percent (66 ⅔%) of the outstanding shares of voting stock of the Company. Abstentions and broker non-votes will have the same effect as a vote against this proposal. The Board of Directors recommends a vote “FOR” the approval of Advanced Energy’s Second Amended and Restated Certificate of Incorporation to provide exculpation from personal liability for certain officers as permitted by Delaware law and make certain other minor, non-substantive updates.

The inspector of election will determine whether or not a quorum is present at the 2024 Annual Meeting. A quorum will be present at the 2024 Annual Meeting if a majority of the shares entitled to vote at the 2024 Annual Meeting are represented at the 2024 Annual Meeting, either by proxy or by the person who owns the shares. In the event there are not sufficient shares of stock entitled to vote present for a quorum or to approve any proposals at the time of the 2024 Annual Meeting, the 2024 Annual Meeting may be adjourned in order to permit further solicitation of proxies. Advanced Energy’s transfer agent will deliver a report to the inspector of election in advance of the 2024 Annual Meeting, tabulating the votes cast by proxies returned to the transfer agent.

You may have received this proxy statement directly from your broker, together with instructions as to how to direct the broker concerning how to vote your shares. Under the rules for Nasdaq-listed companies, brokers cannot vote on certain matters without instructions from you. If you do not give your broker instructions or discretionary authority to vote your shares on such matters and your broker returns the proxy card without voting on a proposal, your shares will be recorded as “broker non-votes” with respect to the proposals on which the broker does not vote. Broker non-votes and abstentions will be counted as present for purposes of determining whether a quorum is present. If a quorum is present, the directors referenced in Proposal 1 will be elected by a plurality of the votes of shares present at the 2024 Annual Meeting (by proxy or in person), Proposals 2 and 3 will be approved by a majority of the shares present at the 2024 Annual Meeting (by proxy or in person), excluding abstentions and broker non-votes, and Proposal 4 will be approved by sixty-six and two-thirds percent (66 ⅔%) of the outstanding shares of voting stock of the Company. Broker non-votes and abstentions will have no effect on the outcome of Proposals 1 – 3 and will have the same effect as a vote against Proposal 4. Cumulative voting shall not be allowed in the election of directors or any of the proposals being submitted to the stockholders at the 2024 Annual Meeting.

    If any other proposals are properly presented to the stockholders at the Annual Meeting, the number of votes required for approval will depend on the nature of the proposal. Generally, under Delaware law and the Second Amended and Restated By-Laws of Advanced Energy, the number of votes required to approve a proposal is a majority of the shares present in person or represented by proxy at the Annual Meeting and entitled to vote, excluding broker non-votes and abstentions. The proxy card provided herewith gives discretionary authority to the proxy holders to vote on any matter not included in this proxy statement that is properly presented to the stockholders at the Annual Meeting. Costs of Solicitation Advanced Energy will bear the costs of soliciting proxies in connection with the Annual Meeting.

Special Note Regarding Forward-Looking Statements This proxy statement contains, in addition to historical information, forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. Statements herein that are not historical information are forward-looking statements. For example, statements relating to Advanced Energy’s beliefs, expectations, and plans are forward-looking statements, as are statements that certain actions, conditions, events, or circumstances will continue. The inclusion of words such as “anticipate,” “expect,” “estimate,” “can,” “may,” “might,” “continue,” “enable,” “plan,” “intend,” “should,” “could,” “would,” “will,” “likely,” “potential,” “believe,” and similar expressions and the negative versions thereof indicate forward-looking statements; however, not all forward-looking statements may contain such words or expressions. Although Advanced Energy believes that the expectations reflected in or suggested by these forward-looking statements are reasonable, the Company may not achieve the results, performance, plans, or objectives expressed or implied by such forward-looking statements. Forward-looking statements involve risks and uncertainties, which are difficult to predict and many of which are beyond Advanced Energy’s control. Actual results could differ materially and adversely from those expressed in any forward-looking statements, and you are cautioned not to place undue reliance on forward-looking statements.

    to these differences or prove the forward-looking statements herein, by hindsight, to be overly optimistic or unachievable include the risk factors described in Advanced Energy’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and other reports and statements filed with the SEC, which can be obtained from the SEC’s website at www.sec.gov or from Advanced Energy’s Investors page at ir.advancedenergy.com. Other factors might also contribute to the differences between these forward-looking statements and Advanced Energy’s actual results. All forward looking statements are based on management’s current estimates, projections and assumptions, and Advanced Energy assumes no obligation to update them.

    Appendix A - Reconciliation of Non-GAAP Measures The “Compensation Discussion & Analysis” and “Pay versus Performance” sections of this proxy statement include references to certain financial measures that are not recognized under generally accepted accounting principles (“GAAP”). These non-GAAP measures exclude the impact of non-cash related charges, such as stock-based compensation, amortization of intangible assets, and long-term unrealized foreign exchange gains and losses. In addition, we exclude discontinued operations and other non-recurring items such as acquisition-related costs, facility expansion and related costs, restructuring, asset impairments, and other charges, as they are not indicative of Advanced Energy’s ongoing performance. The tax effect of our non-GAAP adjustments represents the anticipated annual tax rate applied to each non-GAAP adjustment after consideration of their respective book and tax treatments. In addition, the tax effect also includes a discrete tax benefit associated with the release of a portion of our deferred tax asset valuation allowance. Reconciliations of these non-GAAP measures to the most directly comparable financial measures calculated and presented in accordance with GAAP are provided in the financial tables below. We believe that these non-GAAP measures provide useful information to management and investors to evaluate business performance without the impacts of certain non-cash charges, non-economic foreign currency remeasurements, and other cash charges which are not part of our usual operations. We use these non-GAAP measures to assess performance against business objectives, make business decisions, develop budgets, forecast future periods, assess trends, and evaluate financial impacts of various scenarios. As discussed in “Compensation Discussion & Analysis” above, the incentive plans for our named executive officers include these non-GAAP measures as criteria for achievements. Non-GAAP measures should not be considered in isolation and should not be considered superior to, or a substitute for, financial measures calculated in accordance with GAAP. To gain a complete picture of all effects on our financial results from any and all events, management does (and investors should) evaluate our results of operations in conjunction with the corresponding GAAP measures, as the use of non-GAAP measures has limitations in that the non-GAAP measures are not prepared in accordance with GAAP or based on any comprehensive set of accounting rules or principles, may be different from non-GAAP measures used by other companies, and may exclude certain items that may have a material impact upon our reported financial results.
