At the Annual Meeting, stockholders will vote to elect the eleven director nominees named in this proxy statement as directors.

Our Board of Directors has nominated each of David M. Cote, Giordano Albertazzi, Jacob Kotzubei, Matthew Louie, Roger Fradin, Steven S. Reinemund, Joseph van Dokkum, Edward L. Monser, Joseph J. DeAngelo, Jakki L. Haussler and Krishna Mikkilineni to serve as directors for terms expiring at the 2027 annual meeting of stockholders and until each of their successors has been duly elected and qualified. The persons named as proxies will vote to elect each of David M. Cote, Giordano Albertazzi, Jacob Kotzubei, Matthew Louie, Roger Fradin, Steven S. Reinemund, Joseph van Dokkum, Edward L. Monser, Joseph J. DeAngelo, Jakki L. Haussler and Krishna Mikkilineni unless a stockholder indicates that his or her shares should be withheld with respect to one or more of such nominees.

In the event that any nominee for director becomes unavailable or declines to serve as a director at the time of the Annual Meeting, the persons named as proxies will vote the proxies in their discretion for any nominee who is designated by the current Board of Directors to fill the vacancy, or will otherwise disregard any proxies if there are no such alternative nominees. All the nominees (except for Krishna Mikkilineni) are currently serving as directors and we do not expect that the nominees will be unavailable or will decline to serve. Information about each of the director nominees is set forth below.

Nominees for Election

The following sets forth certain information about our directors as of the date of this proxy statement.

Directors

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Board Composition

Following the Annual Meeting, our Board of Directors will consist of eleven directors. In accordance with our certificate of incorporation and bylaws, the number of directors on our Board of Directors will be determined from time to time by the Board of Directors.

Each director is to be elected annually and to hold office until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal. Vacancies and newly created directorships on the Board of Directors may be filled at any time by the remaining directors.

Director Independence

The rules of the New York Stock Exchange (“NYSE”) require that a majority of our Board of Directors be independent. An independent director is defined generally as a person that, in the opinion of the company’s Board of Directors has no material relationship with the listed company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the company) that would be inconsistent with a determination that the director is independent in accordance with independence requirements under our Corporate Governance Guidelines and as implemented by NYSE. Our Board has determined that nine of our director nominees, being each of Joseph J. DeAngelo, Joseph van Dokkum, Roger Fradin, Jakki L. Haussler, Jacob Kotzubei, Matthew Louie, Krishna Mikkilineni, Edward L. Monser and Steven S. Reinemund, are independent under applicable SEC and NYSE rules.

Board of Directors Leadership Structure

The Board recognizes that one of its key responsibilities is to evaluate and determine its optimal leadership structure to ensure oversight of management and a high-functioning, engaged Board. When evaluating the structure, the Board may take into consideration a variety of criteria, such as, but not limited to, strategic priorities, skillsets of the independent directors, current market environment, the strengths and talents of Vertiv’s management team, and stockholder feedback. Thus, instead of taking a “one-size-fits all” approach to Board leadership, the Board selects the structure that it believes will provide the most effective leadership and oversight for the Company, taking into consideration the Company’s needs and circumstances at any given time.

We do not have a policy on whether or not the role of chairman and CEO should be separate or combined and, if it is to be separate, whether the chairman should be selected from the non-employee directors or be an executive officer. This approach provides the Board with flexibility to determine whether the two roles should be separate or combined based upon the Company’s needs in light of the dynamic environment in which we operate and the Board’s assessment of the Company’s leadership needs at such time.

Currently, we separate the roles of chairman of the Board of Directors and CEO. Mr. Cote serves as the Executive Chairman of our Board of Directors. This structure enables the Board of Directors to effectively exercise its role in oversight of our management team while allowing our CEO to focus on the management of the day-to-day operational execution of our business.

Mr. Cote’s role as Executive Chairman includes acting as the primary liaison between senior management and the independent directors, and providing strategic leadership, advice and counsel based on his experience and expertise to our executive officers. In his support of the management team in their decision-making processes and implementation of strategy, management and the Executive Chairman may communicate daily, and Mr. Cote attends regular meetings with management.

With input from the other board members, committee chairs, and senior management, Mr. Cote develops the agenda for board meetings, sets board meeting schedules, and presides over meetings of the Board of Directors. As Vertiv’s Executive Chairman and board member since the Business Combination, Mr. Cote combines a detailed and in-depth knowledge of Vertiv’s day-to-day operations with an ability to identify strategic priorities essential to Vertiv’s future success, which enables him to effectively advise our management team on key strategies and the execution and implementation processes necessary to achieve Vertiv’s strategic plans. Mr. Cote leads the executive sessions of the independent directors focused on an agenda developed by Committee Chairs to address the most critical issues of Vertiv. In this role, he helps assure that such sessions remain effective forums for promoting open and candid discussion among the independent directors regarding issues of importance to Vertiv, including evaluating the performance and effectiveness of members of our management team.

Board of Directors Role in Risk Oversight

It is the duty of our Board of Directors to serve as a prudent fiduciary for stockholders and to oversee the management of our Company. The specific risk areas of focus for the Board of Directors and each of its Committees are summarized below.

-  2026 Proxy Statement | 17

Attendance at Board of Directors and Committee Meetings and Annual Meeting

During the year ended December 31, 2025:

In the year ended December 31, 2025, all members of our Board of Directors attended at least 75% of the aggregate of: (i) the total number of meetings of the Board of Directors (held during the period for which he or she has been a director) and (ii) the number of meetings held by all Committees of the Board of Directors (during the periods that he or she served on such Committees).

According to our Corporate Governance Guidelines, our directors are expected to make reasonable best efforts to attend the Annual Meeting, meetings of the Board of Directors and meetings of Committees on which they serve. Ten of our directors in office at the time of our 2025 annual meeting of stockholders attended the meeting. Directors are expected to review meeting materials prior to Board of Directors and Committee meetings and management will make appropriate personnel available to answer any questions a director may have about any aspect of the Company’s business.

Board Committees

Our Board has three standing Committees: an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee, each of which is composed solely of independent directors. Each Committee operates under a charter that was approved by our Board and has the composition and responsibilities described below. The charter of each Committee is available on the investors page of our website at https://investors.vertiv.com/corporate-governance/documents/default.aspx.

Audit Committee

The members of our Audit Committee are Steven S. Reinemund, Jakki L. Haussler, Matthew Louie, and Edward L. Monser. Mr. Reinemund serves as the Chairman of the Audit Committee.

-  2026 Proxy Statement | 19

The charter also provides that the Compensation Committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, independent legal counsel or other adviser and is directly responsible for the appointment, compensation and oversight of the work of any such consultant, counsel or adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the Compensation Committee will consider the independence of each such consultant, counsel, or adviser, including the factors required by the NYSE and the SEC.

Nominating and Corporate Governance Committee

The members of our Nominating and Corporate Governance Committee are Joseph van Dokkum, Joseph J. DeAngelo, Roger Fradin, Matthew Louie, and Edward L. Monser. Mr. van Dokkum serves as the chairman of the Nominating Committee. Our Board has determined that each member of the Nominating and Corporate Governance Committee meets the independence and other requirements of the NYSE and the SEC to serve on the Nominating and Corporate Governance Committee.

We have adopted a Nominating and Corporate Governance Committee charter, which details the purposes and responsibilities of the Nominating and Corporate Governance Committee, including, among other things:

The charter also provides that the Nominating and Corporate Governance Committee may, in its sole discretion, retain or obtain the advice of, and terminate, any search firm to be used to identify director candidates, and is directly responsible for approving the search firm’s fees and other retention terms.

We have not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, our Board of Directors considers: experience, skills, expertise, diversity, personal and professional integrity, character, business judgment, time availability in light of other commitments, dedication, conflicts of interest, applicable listing standards and such other relevant factors that the Nominating and Corporate Governance Committee considers appropriate in the context of the needs of the Board of Directors.

Policy Regarding Director Nominations

Our Nominating and Corporate Governance Committee utilizes a broad approach for identification of director nominees and may seek recommendations from our stockholders and/or engage a search firm. In evaluating and determining whether to ultimately recommend a person as a candidate for election as a director, the Nominating and Corporate Governance Committee evaluates all factors that it deems appropriate, including the number of current directors, as well as the qualifications set forth in our Corporate Governance Guidelines, including experience, skills, expertise, diversity, personal and professional integrity, character, business judgment, time availability in light of other commitments, dedication, conflicts of interest and such other relevant factors that it considers appropriate in the context of the needs of the Board of Directors.

In its discretion, the Nominating and Corporate Governance Committee will also consider recommendations of qualified nominees by stockholders by evaluating the same factors as described above.

20 |				-  2026 Proxy Statement

In addition to the process described above, our bylaws permit stockholders to nominate directors for election at an annual meeting of stockholders. To nominate a director, the stockholder must meet certain deadlines established by our bylaws and provide certain information required by our bylaws. For a description of the process for nominating directors in accordance with our bylaws, see “Additional Information” in this proxy statement.

Communication with the Board of Directors

Any stockholder or other interested parties who would like to communicate with our Board of Directors, the independent directors as a group or any specific member or members of our Board of Directors should send such communications to the attention of our Corporate Secretary, at Vertiv Holdings Co, 505 N. Cleveland Avenue, Westerville, Ohio 43082. Communications should contain instructions on which member or members of the Board of Directors the communication is intended for, if applicable. In general, such communication will be forwarded to the intended recipients. However, the Corporate Secretary may, in her discretion, decline to forward any communications that are abusive, threatening or otherwise inappropriate.

Code of Conduct

We have adopted a Code of Conduct that applies to all of our directors, officers, and other employees, including our principal executive officer, principal financial officer, principal accounting officer or controller or persons performing similar functions. The Code of Conduct is available on the investor page of our website, https://investors.vertiv.com/corporate-governance/documents/default.aspx. We intend to make any legally required disclosures regarding amendments to, or waivers of, provisions of our Code of Conduct on our website.

Director Compensation

Director Compensation Policy

The following table shows the cash compensation structure for non-employee directors for 2025.

In addition, each non-employee director received an annual equity grant consisting of stock options with four-year annual ratable vesting. Consistent with its executive compensation philosophy, the Board believed that stock option awards served as an appropriate long-term incentive because our directors would only realize value if the stock price increased, aligning their long-term interests with those of our public stockholders. Stock options have an exercise price equal to the closing price of our stock on the grant date. As a result, the Compensation Committee believes that stock options are an important and effective part of director compensation because the value of the awards to our directors is directly tied to and predicated on increases in our stock price after the grant date, for which our stockholders benefit. In order for the directors to realize any value in the stock options, the stock price must exceed the grant date price subsequent to vesting of the options. In addition, the four-year vesting schedule encourages a focus on the long-term, sustainable performance of our company for the benefit of our shareholders. In determining the amount of options to grant in 2025, the Board and Compensation Committee considered the amount that would be appropriate considering the four-year vesting period, rather than targeting a specific accounting value, and so for the directors other than our Executive Chairman, granted a set number of options, the same number of options granted during the prior year. Due to the increase in our stock price, this resulted in a higher grant date value determined for accounting purposes for options than in the prior year. This grant date value reflected in the table below does not necessarily reflect the value that will actually be realized, since stock options only have value if our share price remains above the exercise price through at least the vesting period. Our directors were also permitted to receive an additional equity award in lieu of the cash retainer fee, as reflected in the table below.

We believe that our director compensation levels are necessary and appropriate in order to attract and retain outstanding talent who possess the proper skillsets to drive Vertiv’s short- and long-term strategies to create long term value for our stockholders. Our Committee Chairs receive higher levels of cash retainers in acknowledgement of the additional workload in leading these Committees. The Compensation Committee has also reviewed peer group data.

Our Executive Chairman receives a higher level of compensation, due to the active role he plays and significant time commitment he makes in leading the Board and helping management set and implement our short- and long-term strategies,

-  2026 Proxy Statement | 21

particularly given his prior executive and operational experience. The Executive Chairman takes an active role with our CEO and management and has been an integral part of our efforts to operationalize our strategies aimed at growing and investing in our business, our operations and our technology offerings, and mitigating the economic, geopolitical, and operational challenges we have faced. As such, the Compensation Committee and the Board believed that retaining a similar aggregate retainer amount for our Executive Chairman was appropriate. For 2025, the amount was paid in the form of a stock option grant in lieu of a cash retainer. His equity award will not have value unless the stock price increases from the grant date through the vesting schedule.

Vertiv reimburses directors for reasonable and necessary out-of-pocket expenses incurred in attending Board and Committee meetings or performing other services in their capacities as directors. The Board expects to review director compensation periodically to ensure that the director compensation package remains competitive such that Vertiv is able to recruit and retain qualified directors.

Director Compensation Table

This CD&A summarizes the details of executive compensation decisions along with several of our business highlights in 2025.

Features of our executive compensation program for 2025 included:

2025 Summary

Under the strong leadership of our CEO, Mr. Albertazzi, we have experienced significant improvements in our operational execution, technology and innovation developments, growth in our capabilities and product and service offerings, and historic

financial results in 2025, as further described below. Under his focused leadership, we had positive operational and financial gains from our M&A strategy, particularly with the additions of Waylay, a generative AI software technology leader that will enhance our predictive analytics offerings, Great Lakes, a leading data rack enclosure and integrated infrastructure solutions provider to bolster our IT systems offerings for AI and high-performance compute applications, and PurgeRite, a fluid management services provider that will enhance our liquid cooling offers for high-density and AI applications. Further, we continued to invest in manufacturing and capacity expansions and capabilities to meet the growing demand of our customers and the unprecedented growth of data and AI adoption.

Our executive compensation for 2025 reflected these successes, particularly as the Compensation Committee considered appropriate incentives for our CEO for both short-term financial results and long-term equity interests, as further described in this CD&A.

2025 was a year of continued financial strength and transformative operational growth. The continued rapid growth of data, and the robust demand for, and acceleration of, AI technology adoption and high-performance compute resulted in strong demand for the Company’s innovative critical digital infrastructure products, software and services. The following is a summary of key 2025 financial results:

We actively engage with stockholders throughout the year to better understand their issues and concerns, including, but not limited to, their perspective on executive compensation. We hold a “say-on-pay” advisory vote on an annual basis. In 2025, we received approval of approximately 87% of votes cast on our “say-on-pay” advisory vote. Feedback from stockholders informs the Compensation Committee’s consideration of executive compensation programs. The Board and the Compensation Committee aim to align business performance and executive compensation to drive value creation by directly tying compensation to key performance metrics, and placing significant weight on compensation that varies in value depending upon stock price performance.

Our shareholder return during 2025 was more than 42%. During 2025, we declared quarterly cash dividends each for $.0375 per share in the first three quarters of the year, and in light of strong financial performance, increased the cash dividend to $.0625 per share in the fourth quarter, for an aggregate of $.175 per share.

The following graph shows our total shareholder return for 2025, as compared to the performance of other market sectors, including the companies listed in the Compensation Peer Group (defined below).

The following charts show the mix of the primary compensation elements for 2025 for our CEO and our other NEOs, including salary, target annual cash incentive, annual long-term incentive awards granted during the year and other benefits.⁽¹⁾ As reflected in the charts below, we have structured executive compensation, particularly for the CEO, to be performance-based and aligned with stockholder value.

Mr. Albertazzi’s primary compensation for 2025 is summarized below. The determination of the cash bonus based on performance is further described below. As further described below, our CEO’s compensation for 2025 is reflective of the Compensation Committee’s review of his leadership and execution of our strategic initiatives, including technology and innovation development, capacity and capabilities expansions, strategic acquisitions that enhanced our capabilities, product, and service offerings, and improved operational performance (such as tariff and inflation mitigation, supplier resiliency, VOS) that is delivering robust value to shareholders, as well as considerations around his total compensation within our Compensation Peer Group.

Objectives of Executive Compensation Program

The following table provides an overview of the specific objectives of the primary elements of our 2025 executive compensation program, each as further described below.

-  2026 Proxy Statement | 31

Our focus for the 2025 Vertiv Incentive Plan (“VIP”) was to align employees under a common set of goals tied to adjusted operating profit and adjusted free cash flow, both of which help us to maintain our focus on improving Vertiv’s operational execution and financial performance and driving stockholder value, while also recognizing our overall performance, segment and regional performance, and individual contributions to our long-term goals.

Corporate Financial Results

The following table shows our corporate performance for the two financial metrics under the VIP for 2025:

2025 Annual Equity Grants. In furtherance of our performance-based compensation philosophy and strong alignment with stockholder interests, our annual equity compensation granted in early March 2025 to NEOs consisted of stock options that vest annually over four years. Each named executive officer was granted an award of stock options in the amounts set forth in the table entitled “Grants of Plan-Based Awards in Fiscal 2025” below and with pro rata vesting annually over four years.

The amount granted to each continuing NEO was generally based on each individual’s duties and responsibilities, internal pay equity considerations, and prior equity grants to each individual. The Compensation Committee continued to believe that time-vesting stock options were the appropriate long-term performance vehicle for annual grants. Granting stock options is beneficial to the Company for the following reasons:

34 |				-  2026 Proxy Statement

CEO Equity Grants for 2025. Our CEO received an increased equity grant in the form of stock options in 2025. As part of considerations around increasing his total targeted compensation to reflect both his performance and a review of appropriate peer group compensation, the Compensation Committee sought to ensure that a significant portion of his overall compensation is aligned with our pay for performance culture and further aligned directly with our shareholders and shareholder value realization. Thus, the Compensation Committee believed that a significant investment in our equity and value tied to our stock price performance was important for the CEO in particular. The grant date value set forth in the Summary Compensation Table represents the value determined for accounting purposes. The value of these stock options will depend on our CEO helping deliver stock price performance for our stockholders over the vesting period of the stock options. These stock options combine with his prior Strategic Performance Award to tie a significant portion of his potential compensation to both financial results and stock price results.

2022 Strategic Performance Awards (Results for Third Tranche). As previously disclosed, in 2022 (and for promotions in subsequent years including for Mr. Armul in 2025), our named executive officers received strategic, long-term performance awards (the “Strategic Performance Awards”) intended to incentivize the executive management team to achieve multi-year key goals for the business and to promote the long-term retention of the business leaders that we need to attain our goals. These Strategic Performance Awards vest, to the extent earned, contingent on both (i) achievement of strategic AOP targets in 2023, 2024 and 2025 and (ii) continued employment through January 1, 2027, with limited exceptions related to death, disability, or, in connection with a change in control, termination of employment or of the award.

For any portion to be earned for a year, a target AOP performance goal (“Target AOP”) must be achieved for the applicable year. The following chart shows the targets for each year, along with the results for each of the performance periods.

If the Target AOP was exceeded in any given year, each grantee earned an additional 20% of their respective target award level for each $50 million increment that AOP performance exceeded the Target AOP (with no interpolation between results). Pursuant to the terms of the award agreements, the dollar value of the total earned award was converted into RSUs on February 12, 2026, based on the closing price on that date. These RSUs will be eligible for cliff vesting on January 1, 2027.

The Strategic Performance Awards continue to be beneficial to the Company for the following reasons:

The financial measure and target levels were selected for the following reasons:

2026 Strategic Performance Awards (Initial Grant). With the conclusion of the performance periods of the 2022 Strategic Performance Awards and the benefits of those awards to the Company (as referenced above), the Compensation Committee has decided to continue with a similar long-term performance equity program in 2026 based on the Company earnings per share (“EPS”). Similar to the 2022 plan program, the 2026 plan program is designed to incentivize the Company’s executive management team to achieve multi-year key goals for the business and to promote the long-term retention of the business leaders that the Company needs to attain such goals. Like the 2022 awards, the 2026 awards, if earned, will vest over a four-year period, but instead of AOP targets, the awards will be subject to the achievement of the following annual EPS targets:

-  2026 Proxy Statement | 35

An additional 20% of annual performance plan bonus target will be awarded for every $0.15 EPS achieved over each year’s target EPS.⁽¹⁾ The awards will be subject to continued employment with the Company through January 1, 2030, with certain limited exceptions. The EPS goals are considered to be stretch goals by the Board, thereby incentivizing management to exceed the EPS outlook that Vertiv has publicly disclosed previously. If target EPS is not achieved for a performance period, no amounts will be earned for such period. The awards are subject to forfeiture in the event that an executive breaches their non-competition, non-solicitation and confidentiality obligations to the Company, as well as the Company’s clawback policy. The awards will otherwise have terms and conditions consistent with the 2022 Strategic Performance Awards and the form of award agreement previously disclosed.

New Hire Equity Compensation. In connection with hiring our new CFO, we entered into an offer letter which provided for new hire compensation. In order to make up for potential lost compensation opportunities, and to induce him to accept our offer, we granted him RSUs with a grant date value of $1,050,700. Because of the special nature of this award, the vesting schedule was specific to this award, with installments of 50% in November 2026, 30% in November 2027, and 20% in November 2028.

Our tax-qualified employee savings and retirement plan (“401(k) Plan”) covers certain full- and part-time employees in the United States, including our U.S.-based NEOs. Under the 401(k) Plan, employees may elect to reduce their current compensation up to the statutorily prescribed annual limit and have the amount of such reduction contributed to the 401(k) Plan. The Board believes that the 401(k) Plan provides an important and highly valued means for employees to save for retirement. We provide a match of 50% of the first 6% of the named executive officers’ eligible base salary. Our eligible NEOs were eligible to participate in the 401(k) Plan on the same terms as our other employees in 2025. Our executive officers outside the U.S. are eligible for applicable local retirement plans.

General. The protection of competitive and confidential information and the retention of top talent are of the utmost importance to Vertiv. For this reason, our named executive officers are subject to confidentiality, non-compete and non-solicitation covenants. Each named executive officer generally was subject to our Executive Employment Policy (or for some of our non-U.S. executive officers, an employment agreement with similar benefits) and our “double-trigger” Executive Change of Control Plan, in each case that provide for severance benefits following a qualifying termination of employment, which is intended to alleviate concerns about job security that could affect performance and keep the named executive officers focused on their day-to-day responsibilities. A detailed description of these severance and change of control benefits, along with estimates of the value of the benefits potentially payable under these arrangements, are set out below under the caption “Potential Payments upon Termination or Change-in-Control.”

CFO Transition. In May 2025, we announced that Mr. Fallon would be departing from his position as CFO, subject to the Company finding a successor. We subsequently hired a new CFO, Mr. Chamberlin, in November 2025. As part of the Company’s efforts to ensure a successful transition by both retaining Mr. Fallon through a significant search period and engaging him to support the transition after his departure as CFO, the Company entered into a Transition and Consulting Agreement with Mr. Fallon (the “Transition Agreement”), pursuant to which he agreed to remain as a consultant through 2026. He remained eligible to receive a prorated incentive payment for 2025 based on the time he served as CFO, in an amount depending on actual Company performance. There are no other cash payments during the consulting period. He also remained eligible for vesting of stock options scheduled to vest in the ordinary course in March 2026 during the consulting period. All other unvested equity awards, including the strategic performance award, are forfeited. All of his vested options will remain exercisable through December 31, 2028. Mr. Fallon remains subject to restrictive covenants and provided the Company with a general release.

All of the named executive officers in the United States were eligible for coverage under our health insurance programs, including medical, dental and vision, a health savings account and flexible spending accounts. Additionally, the named executive officers were eligible for life insurance, short- and long-term disability benefits and paid time off. Officers in other jurisdictions are generally eligible for available benefit programs in the applicable jurisdiction.

We may provide additional benefits in particular circumstances. For example, for executives required to relocate to the U.S. for new positions, in some cases we have agreed to provide reimbursement for fees paid in connection with the filing of U.S. and non-U.S. tax returns, tax equalization benefits, and other related items. The compensation for Mr. Sanghi reflects these types of benefits, as described in the footnotes to the Summary Compensation Table. We also provide relocation benefits.

Peer Group Companies

The Compensation Committee believes that we should provide market-competitive pay, with higher amounts based on tenure, job responsibilities and performance, and that long-term incentive compensation should be a significant component of executive compensation. The Compensation Committee expects to review annual benchmarking using a peer group representing a set of companies in the industries in which we compete.

The Compensation Committee has worked with management to represent companies comparable in terms of size, industry, revenue and/or market cap, with a focus on a method for considering other companies that are subject to the same impacts in our market and industry. The Compensation Committee did not make changes for 2025. As a result, the peer group used when evaluating 2025 compensation consisted of the companies below (“Compensation Peer Group”). In addition, we may from time to time review compensation practices of other companies that are competitors for talent, in order to better understand the competitiveness of Vertiv’s compensation programs with the goal of preserving talent.

Compensation Risk Assessment

As part of our risk management activities, management reviews with the Compensation Committee its compensation policies and practices applicable to employees that could affect our assessment of risk and risk management. The Compensation Committee and management believe that our compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on Vertiv.

Tax and Accounting Considerations

The tax and accounting impacts of our executive compensation program are among many factors that may be considered in determining the size and structure of our executive compensation program. Section 162(m) of the Internal Revenue Code of 1986, as amended (“Code”), denies a publicly traded corporation a federal income tax deduction for remuneration in excess of $1 million per year per person paid to executives designated in Section 162(m) of the Code. We have not adopted a policy that requires that all compensation be deductible.

Stock Ownership Guidelines for Our Officers and Directors

Our directors, named executive officers and other designated individuals are expected to own our stock based on the following multiple-of-salary ownership threshold guidelines.

Directors and officers are expected to comply with the multiple-of-retainer/salary stock ownership guidelines, generally by the later of five years from appointment to the relevant role or February 7, 2025. Additionally, if an executive officer is promoted to a higher level, that person will have three years to achieve the higher stock ownership guideline. Once the individual has acquired a number of our shares that satisfies the ownership multiple, such number of shares shall represent that person’s minimum ownership requirement (even if that person’s salary increases or the fair market value of such number of shares subsequently falls below the required ownership multiple) until (in the case of an executive officer) such person is promoted to a higher level. The Company has adopted a “no sale” restriction that restricts an executive officer from selling stock unless and until such individual has met or exceeds ownership guidelines (provided, however, that an individual is prohibited from selling if they don’t satisfy the guidelines without the earned but unvested performance shares). All of our executive officers and directors have met or are anticipated to meet these guidelines within the applicable timeframes.

-  2026 Proxy Statement | 37

For purposes of satisfying the requirements of the stock ownership guidelines, ownership includes stock owned privately, shares (or equivalent shares) awarded to, or purchased by, an officer or director pursuant to a qualified or non-qualified benefit or savings plan, shares acquired on exercise of stock options or settlement of vested RSUs, unvested restricted stock units, or unvested but earned strategic performance awards (that is, assuming the applicable target performance for that year has been achieved). No options or unearned performance awards are included. For purposes of satisfying the requirements of the stock ownership guidelines, ownership also includes shares as to which the officer or director has a direct or indirect pecuniary interest including shares held by a spouse or child and generally includes shares held through family trusts (such as GRATs) and other family entities.

Compensation Committee Interlocks and Insider Participation

None of the directors who are currently or who were members of our Compensation Committee during 2025, are either currently, or have been at any time, an officer or employee of Vertiv. None of our executive officers currently serves, or served during 2025, as a member of the Board or Compensation Committee of any entity while one or more of its executive officers was serving as a member of our Board or Compensation Committee.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis contained herein with management. Based on its review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and in this proxy statement.
