2025 Performance

2025 was a year of strong execution and market leadership. We capitalized on unprecedented demand for AI and high-performance compute infrastructure, delivering exceptional financial performance while expanding capacity, deepening strategic partnerships, and strengthening our technology leadership. The numbers tell a compelling story: net sales reached $10.2 billion, up 28% year-over-year. Operating profit jumped 34% to $1.8 billion. Adjusted operating margin expanded 100 basis points to 20.4% — demonstrating our ability to scale profitably. Operating cash flow increased 60% to $2.1 billion and adjusted free cash flow increased 66% to $1.9 billion, providing significant financial flexibility. Our backlog reached $15.0 billion at year-end, up 109% year-over-year. These numbers reflect our customers’ confidence in our ability to deliver the infrastructure that AI demands.

We stand at the center of the industry’s transformation, positioned to deliver sustained value creation for our shareholders, customers, and employees while maintaining our leadership in technological innovation.

##### Table of Contents

Strategic Compensation-Related and Other Actions to Position Us for Long-Term Growth

✓ | Capacity and Technology Expansion. We invested in capacity expansion to meet current and anticipated customer demand. We expanded our global footprint and scaled our services capabilities to over 5,000 field service engineers worldwide. As AI and high-performance compute continue transforming the data center industry, we invested heavily in innovation — ER&D spending grew 20% in 2025. We launched breakthrough solutions including Vertiv™ OneCore, our complete converged data center infrastructure solution, and Vertiv™ SmartRun, our prefabricated whitespace infrastructure that accelerates data hall fit-out. We expanded our liquid cooling and thermal management technologies to serve next-generation AI applications.

✓ | Strategic Acquisitions. We deployed approximately $1.2 billion for strategic acquisitions while maintaining our strong balance sheet. Great Lakes expanded our customized racks and cabinets capabilities for AI infrastructure. Waylay strengthened our digital services with AI-enabled advanced monitoring. PurgeRite enhanced our specialized fluid management capabilities for liquid cooling systems. Each acquisition deepened our capabilities and strengthened our portfolio.

✓ | Strategic Partnerships. We deepened collaboration with NVIDIA on next-generation AI infrastructure and 800 VDC power architectures. We partnered with Caterpillar and Oklo on on-site power generation for gigawatt-scale AI infrastructure, reducing deployment timelines from years to months. These partnerships address critical industry challenges and position us to enable the infrastructure that AI demands.

Compensation Packages Are Strongly Aligned with Stockholder Interests

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 (in the form of stock options) 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.

(1) | Excludes our new CFO given his start date late in the year. Long-Term Incentive reflects equity awards actually granted during 2025, not any modifications, and does not include the one-time performance equity award to Mr. Armul.

CEO Compensation Is Focused on Variable Pay

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 expansion, 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.

See also the “Compensation Discussion and Analysis” below for a discussion of considerations in approving his increased compensation for 2025.

2025 CEO Compensation |  |  |
Base Salary (as of 12/31/25) |  |  | $1,300,000 |
Target Cash Bonus (as % of Base Salary) |  |  | 150% |
Actual Cash Bonus (for 2025 performance) |  |  | $4,000,000 |
Approximate Grant Date Fair Value of Annual Equity Awards Granted |  |  | $13.04 M |

Corporate Governance Highlights

✓ | Annual Full Board Elections. We provide for director elections on an annual basis to provide our stockholders with regular input on the composition of our Board of Directors.

✓ | Separate Chairman and CEO Roles. We believe that, at this time, our continuing separation of the roles of CEO and Chairman enables the Board of Directors to effectively exercise its role in oversight of Vertiv while allowing our CEO to focus on the management of the day-to-day conduct of our business. See “Board of Directors Leadership Structure” below for further information.

✓ | Code of Conduct. We have a code of conduct that applies to all 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, along with other corporate governance documents, is available on our website, https://investors.vertiv.com/corporate-governance/documents/default.aspx.

✓ | No Poison Pill. Vertiv does not maintain a poison pill or stockholder rights plan.

|  |  |  |  |  |  |  |  |  |  |  | -  2026 Proxy Statement|3

##### Table of Contents

✓ | Robust Stock Ownership Guidelines. We require executive officers and directors to hold meaningful amounts and values of stock and to meet certain other guidelines, as further set forth below under “Stock Ownership Guidelines for Company Officers and Directors.” Further, the Company adopted a “no sale” restriction that restricts an executive officer from selling stock until such officer has met or exceeds ownership guidelines. All of our executive officers and directors have met or are anticipated to meet these guidelines within the applicable time period.

✓ | Prohibition of Hedging and Pledging. Our insider trading policy prohibits our officers, directors and employees from hedging or pledging our shares.

Commitment to Responsible Business Initiatives

In 2025, we continued to strengthen and improve our responsible business program and advance our efforts through a range of responsible business initiatives. In particular:

✓ | Reporting — We issued our fourth annual Responsible Business Report in 2025, which was aligned to certain elements of the Sustainability Accounting Standards Board (“SASB”) and Global Reporting Initiative (“GRI”) frameworks, as well as select United Nations Sustainable Development Goals (“UNSDGs”) that we view as most relevant to our business.

✓ | Governance — We continued to hold ourselves to high governance standards. In 2025, our Responsible Business Steering Committee continued to enhance and further develop our responsible business strategies, evaluate related disclosure frameworks for public reporting, and keep our Board of Directors apprised of various responsible business topics.

✓ | Responsible Products and Solutions — We continued our technology innovation, and developed products, services, and solutions that helped enable our customers to meet their energy and water efficiency and environmental-related objectives across increasingly high-density and AI-enabled digital infrastructure environments. Our portfolio includes integrated power, thermal, and modular infrastructure solutions designed to support higher efficiency, improved resource utilization, and flexible deployment. These include advanced power systems and battery energy storage solutions, liquid and hybrid cooling technologies, modular and prefabricated infrastructure platforms, and system-level monitoring and controls that help optimize performance across the full data center lifecycle.

| Our approach to meeting our customers’ demands for scalable, reliable digital infrastructure, while helping them manage environmental impacts, rests on five key principles that guide product and technology development and delivery:

| • |  | High efficiency: Designing products and solutions that improve energy, water, materials, and carbon efficiency.

| • |  | High reliability: Building resilient, durable, and serviceable equipment to support long-term operational performance.

| • |  | Low impact: Reducing environmental impacts across product design, materials, and manufacturing processes.

| • |  | Low touch: Enabling remote troubleshooting, diagnostics, and digital services to reduce maintenance-related impacts.

| • |  | Circular economy: Supporting the reuse, refurbishment, and recycling of equipment and materials at end of life.

✓ | Responsible Operations — We continued to benchmark our operations by collecting and evaluating our greenhouse gas emissions inventory and other operational data to inform internal planning, risk management, and continuous improvement efforts. These activities support our focus on improving efficiency across our facilities and processes, managing energy, water, waste, and environmental compliance within our own operations, and complement the efficiencies delivered through our products and solutions to customers.

✓ | Our Neighbors — We believe our success is closely linked to our responsibility to our employees, customers, communities, and other stakeholders, and the values that underpin our corporate culture. In 2025, we continued our charitable contribution efforts, focusing our global community and philanthropic initiatives on supporting STEM education, health research, crisis response, and local community needs.

| Together with our employees and their families, Vertiv supported organizations and activities around the world by providing volunteer services and/or monetary donations. Examples include, Pelotonia, Columbus Crew STEM Day, NC4K Kick Childhood Cancer, and various disaster relief efforts in communities where we operate.

✓ | Our People — As further described in the “Compensation Discussion and Analysis” below, our Compensation Committee demonstrated strong leadership by recognizing and rewarding our management team’s strong performance in delivering transformative financial and operational results by paying above target bonuses, generally, to our NEOs for 2025 and to eligible non-executive employees. These bonuses were paid in recognition of company and individual performance results and are in furtherance of our pay-for-performance culture in an effort to maximize the retention of

4| |  |  |  | -  2026 Proxy Statement |  |  |  |  |  |

##### Table of Contents

| our employees who helped us implement and deliver such results against our strategic framework in 2025. We recognize that our employees are critical to achieving our strategic priorities and business objectives, and investing in them is a key component to our success.

| We provide development and training programs for our employees, including new product training for our sales and services organizations, Leading@Vertiv for our management level employees, and MyFirst90Days for newly hired employees, which serve as key human capital measures and objectives. Additionally, our salaried and services employees participate in a comprehensive annual performance review process designed to encourage direct dialogue and candid feedback to support employee development, career progression, and a high-performance culture.

| Further, we offer leadership development programs for employees at early-career levels in finance, sales, services, and engineering, as well as customized programs for identified talent populations to further develop their skills and capabilities. We also maintain specialized partnership programs with local universities that support the attainment of bachelor’s and/or master’s degrees in technology-related fields.

| Our offerings include:

| • |  | Finance, Sales, Human Resources, Engineering, and Application Engineering leadership development rotational programs for early-career employees based in the Americas, India, or Europe, the Middle East, and Africa.

| • |  | Specialized partnership programs with local universities in India for high-potential engineers to earn a post-secondary baccalaureate and/or graduate degrees.

| • |  | Programs for identified high-potential leaders at early-, mid-, senior-, and leadership-ready levels across multiple functions globally, focused on operational and strategic thinking, global project leadership, and exposure to executive leadership.

| • |  | Specialized training for employees based in our support hubs, located in the Philippines and Romania, focused on key business skills including customer service and finance fundamentals.

| • |  | Vertiv Operating System (VOS) training delivered globally through VOS Academy, offered virtually for salaried employees, with all hourly employees receiving training at global manufacturing sites.

✓ | Safety — We employ a global occupational health and safety management system designed to monitor, track, and improve processes and procedures to enhance employee safety. This system supports continual improvement in our safety programs and is implemented across our operations. We maintain a dedicated team of environmental, health and safety professionals throughout our facilities and service regions, and provide on-site medical services at many of our manufacturing locations.

| We believe a safe and healthy workplace is essential to our business and prioritize the health and safety of our global workforce, contractors, and visitors to our facilities. We are subject to a broad range of foreign and domestic environmental, health and safety laws, regulations, and requirements, and maintain policies, procedures, and controls intended to support compliance and risk management.

| We believe we have an effective employee health and safety strategy, supported by our safety performance relative to certain peers, including our total recordable injury rate of 0.35 and our lost time incident rate of 0.18 for the twelve months ended December 31, 2025.

| Safety is one of Vertiv’s core principles. In connection with our commitment to safety, we provide the tools, training, and other resources intended to reduce and control workplace risks and promote an injury-free workplace. Employee engagement is an important component of our continuous improvement efforts. For example, we continue our safety engagement campaign, “We Lead with Safety,” which reinforces our interdependent safety culture, and encourages employees to speak up regarding safety.

| One way we promote proactive engagement is through our “Good Catch” initiative, which encourages the reporting of safety observations, hazards, and opportunities for improvement. We encourage, value, and recognize employee input, and, through documented procedures, local management teams respond to reported items and implement corrective actions where appropriate. To promote excellence and continuous improvement, we continue to recognize manufacturing facilities and service organizations that demonstrate strong safety culture and performance through our safety award process.

GENERAL INFORMATION

We are making this proxy statement available to our stockholders on or about April 24, 2026 in connection with the solicitation of proxies by our Board of Directors for the Annual Meeting, which will be held on June 17, 2026 at 11:00 a.m. (Eastern Time), via live webcast at the following address www.virtualshareholdermeeting.com/VRT2026. The Annual Meeting will be completely virtual. You may attend the Annual Meeting and vote your shares electronically during the Annual Meeting via live webcast by visiting www.virtualshareholdermeeting.com/VRT2026. You will need the 16-digit control number that is printed on your proxy card, voter instruction form or Notice of Internet Availability of Proxy Materials, to enter the Annual Meeting. Vertiv recommends that you log in 15 minutes before the meeting to ensure you are logged in when the Annual Meeting starts. Please note that you will not be able to attend the Annual Meeting in person. Below are answers to common questions stockholders may have about the Annual Meeting. Our fiscal year ends on December 31.

We have one class of outstanding common stock, our Class A common stock, which has one vote per share. Shares of our common stock generally vote together as a single class on all matters submitted to a vote of our stockholders.

What information is included in this proxy statement?

The information in this proxy statement relates to the proposals to be voted on at the Annual Meeting, the voting process, our Board of Directors, Board Committees and corporate governance matters, the compensation of current directors and certain executive officers for the year ended December 31, 2025, and other information.

What are the Proxy Materials?

The “Proxy Materials” are this proxy statement and our annual report to stockholders, which includes our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (referred to herein as the “Form 10-K”).

Why did I receive a one-page notice in the mail regarding the Internet Availability of the Proxy Materials instead of a full set of the Proxy Materials?

Pursuant to rules adopted by the Securities and Exchange Commission (“SEC”), instead of mailing a printed copy of our proxy materials to each stockholder of record, we have elected to furnish our Proxy Materials via the Internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials to our stockholders. All stockholders will have the ability to access the Proxy Materials on the website referred to in the Notice of Internet Availability of Proxy Materials or request to receive an electronic copy or printed set of the Proxy Materials. Instructions on how to access the Proxy Materials over the Internet or to request an electronic copy or printed copy may be found in the Notice of Internet Availability of Proxy Materials. In addition, stockholders may request to receive the Proxy Materials in printed form by mail or electronically by email on an ongoing basis.

What items will be voted on at the Annual Meeting and how does the Board of Directors recommend that I vote?

There are three proposals to be voted on at the Annual Meeting:

1. | Election of Directors: elect eleven director nominees to our Board of Directors for a term of one year expiring at the annual meeting of stockholders to be held in 2027 and until such director’s successor has been duly elected and qualified;

2. | Say-on-Pay: approve, on an advisory basis, the compensation of our named executive officers as disclosed in the accompanying proxy statement; and

3. | Independent Auditor: ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

The Board of Directors recommends that you vote FOR each nominee in proposal 1, and FOR each of proposals 2 and 3.

Our bylaws provide advance notice procedures for stockholders seeking to bring business before our Annual Meeting, or to nominate candidates for election as directors at any meeting of stockholders. We have not received any such proposals. We do not anticipate any other matters will come before the Annual Meeting. If any other matter comes before the Annual Meeting, the proxy holders appointed by our Board of Directors will have discretion to vote on those matters.

Who may vote at the meeting?

Holders of Class A common stock, together as a single class, as of the close of business on April 20, 2026, the Record Date, may vote at the Annual Meeting.

For proposal 1, the election of directors, each director must be elected by a plurality of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon. This means that the eleven directors receiving the largest number of “FOR” votes will be elected as directors.

Proposal 2, the approval, on an advisory basis, of the compensation of our named executive officers, proposal 3, the ratification of the appointment of the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026, and any other proposals that may properly come before the Annual Meeting must be approved by the affirmative vote of a majority of the votes cast by stockholders present in person or represented by proxy and entitled to vote thereon.

How are abstentions and broker non-votes counted?

Abstentions (shares present at the meeting in person or by proxy that are voted “abstain”) and broker non-votes (explained below) are counted for the purpose of establishing the presence of a quorum but are not counted as votes cast in respect of proposals 1, 2 and 3 to be voted on at the Annual Meeting, and as a result, have no impact on those proposals.

What constitutes a “quorum”?

The holders of a majority of the voting power of the shares of Class A common stock issued, outstanding and entitled to vote at the Annual Meeting, either in person or represented by proxy, constitute a quorum.

What is the difference between a stockholder of record and a beneficial owner of shares held in street name?

• |  | Stockholder of Record. If your shares are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are a stockholder of record.

• |  | Beneficial Owner of Shares Held in Street Name. If your shares are held in an account at a brokerage firm, bank, broker-dealer or other similar organization, then you are a beneficial owner of shares held in street name. The organization holding your account is considered the stockholder of record. As a beneficial owner, you have the right to direct the organization holding your account on how to vote the shares you hold in your account.

How do I vote?

• |  | Vote by Internet. Visit www.proxyvote.com to vote via the Internet. Stockholders of record may submit proxies over the Internet by following the instructions on the Notice of Internet Availability of Proxy Materials or, if printed copies of the Proxy Materials were requested, the instructions on the printed proxy card. Most beneficial stockholders may vote by accessing the website specified on the voter instruction forms provided by their brokers, trustees, banks, or other nominees. Please check your voter instruction form for Internet voting availability.

• |  | Vote by Telephone. Call toll-free 1-800-690-6903 in the United States or from foreign countries from any touch-tone telephone and follow the instructions. Stockholders of record may submit proxies using any touch-tone telephone from within the United States by following the instructions on the Notice of Internet Availability of Proxy Materials or, if printed copies of the Proxy Materials were requested, the instructions on the printed proxy card. Most beneficial owners may vote using any touch-tone telephone from within the United States by calling the number specified on the voter instruction forms provided by their brokers, trustees, banks or other nominees.

• |  | Vote by Mail. Stockholders of record may submit proxies by mail by requesting printed proxy cards and completing, signing and dating the printed proxy cards and mailing them in the pre-addressed envelopes that will accompany the printed Proxy Materials. Beneficial owners may vote by completing, signing and dating the voter instruction forms provided and mailing them in the pre-addressed envelopes accompanying the voter instruction forms. If you are a stockholder of record and you return your signed proxy card but do not indicate your voting preferences, the persons named in the proxy card will vote the shares represented by that proxy as recommended by the Board of Directors. If you are a beneficial owner and you return your signed voter instruction form but do not indicate your voting preferences, please see “How are abstentions and broker non-votes counted?” regarding whether your broker, bank, or other holder of record may vote your uninstructed shares on each proposal.

Cleveland Avenue, Westerville, Ohio 43082, Attn: Secretary, (ii) submitting a later-dated proxy relating to the same shares by mail, telephone or the Internet prior to the vote at the Annual Meeting, or (iii) attending the Annual Meeting virtually and voting at the Annual Meeting via the Annual Meeting website. If you are a beneficial stockholder, you may revoke your proxy or change your vote only by following the separate instructions provided by your broker, trust, bank, or other nominee.

If I hold shares in street name through a broker, can the broker vote my shares for me?

If you hold your shares in street name and you do not instruct your broker on how to vote your shares, the broker or other organization holding your shares can vote on certain routine proposals but cannot vote on other proposals. Proposals 1 and 2 are not considered routine proposals. If you hold shares in street name and do not instruct your broker on how to vote on proposal 1 or 2, your shares will not be voted in respect of those proposals and will be counted as “broker non-votes.” Proposal 3 is a “routine” proposal, and your broker has discretion to vote those shares.

Who is paying for this proxy solicitation?

We have retained Georgeson LLC to solicit proxies, for which we will pay a fee of approximately $12,500.00 plus reasonable out-of- pocket expenses.

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.

Director Compensation

Director Compensation Policy

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

|  | Cash Retainer |
Chairman of the Board |  |  | $      — |
Committee Chair – Audit |  |  | $ 150,000 |
Committee Chair – Compensation |  |  | $ 130,000 |
Committee Chair – Nominating and Corporate Governance |  |  | $ 115,000 |
Other Board Member |  |  | $ 100,000 |

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

##### Table of Contents

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.

(3) | On March 7, 2025, these directors received options to purchase 15,000 shares of Class A common stock (46,012 shares in the case of Mr. Cote), with a per share exercise price of $85.04, which was the closing price of our Class A common stock on the grant date. Mr. DeAngelo received an additional number of options in lieu of the $100,000 cash retainer. These options were approved at the first meeting of the Compensation Committee of 2025, consistent with Vertiv’s Equity Grant Policy, on March 6, 2025, subject to approval by the Board at a meeting on March 7, 2025, with the grants to be effective on March 7, 2025.

(4) | As of December 31, 2025, Mr. Cote, Ms. Haussler, Mr. DeAngelo, and Mr. Van Dokkum held unexercised stock options (vested and unvested) to purchase 543,838, 46,886, 79,170, and 137,294 shares, respectively, and each of the other non-employee directors held unexercised stock options (vested and unvested) to purchase 175,941 shares. The foregoing includes options held by family trusts.

(5) | This column requires reporting the amount of other compensation, including personal benefits or perquisites that exceed $10,000 in the aggregate. This table excludes reimbursements for expenses incurred in attending Board and Committee meetings or performing other services in their capacities as directors. The amount reported reflects the aggregate incremental cost to the Company of the use of the Company’s chartered aircraft for travel that may be deemed to include a personal benefit. Our directors may be accompanied by a spouse or guests on our chartered aircraft while on business travel, which does not result in aggregate incremental cost to the Company.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Our executive compensation program is structured to reward performance consistent with our short-term and long-term goals, to reflect our business strategy and our organizational structure, to support our goal of delivering long-term value to our stockholders and to align with our near-term strategic and operational goals. This Compensation Discussion and Analysis (“CD&A”) reviews the objectives and components of our executive compensation program and discusses the 2025 compensation earned by our named executive officers (or “NEOs”), who are listed below.

Giordano Albertazzi Chief Executive Officer |  | Craig Chamberlin Chief Financial Officer* |  | Anand Sanghi President, Americas |  | Stephanie Gill Chief Legal Officer |  | Scott Armul Chief Product & Technology Officer

* | Mr. Chamberlin became Chief Financial Officer on November 10, 2025. Our former Chief Financial Officer, David Fallon, is also an NEO for 2025.

We are dedicated to a pay for performance philosophy with compensation tied to, and which rewards our executive officers for, both short-term and long-term performance of the Company. 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:

• |  | Pay for performance. Our CEO’s pay opportunities primarily consisted of performance-based compensation, particularly equity compensation in the form of stock options that have value only if our stock price increases following the grant date along with an opportunity to earn a cash bonus based on performance.

• |  | Continued impact of our strategic performance equity awards. Our strategic performance equity awards, initially granted in late 2022, continued to drive performance in 2025. These strategic performance equity awards will be eligible for cliff vesting in January 2027 based on the actual achievement of the stretch annual financial performance goals from 2023 through 2025. For the 2025 performance period, we exceeded the goal, resulting in 220% of the third and final tranche being earned, as further described below. The Compensation Committee continues to believe that the challenging annual performance goals, together with cliff vesting on January 1, 2027 subject to continued employment, were important components of the program to encourage long-term continuity in management and to encourage focus on our operational goals over the three-year performance period. There is no payment on these awards before the vesting date for an earlier termination without cause or resignation for good reason, other than a termination in connection with a change in control or, to the extent already earned based on performance results, on death or disability. Given the conclusion of the performance periods, the Compensation Committee has decided to implement a similar long-term performance equity program in 2026 based on earnings per share (EPS), which is described in further detail below.

• |  | Annual bonus payouts reflecting strong performance. As further described below, bonus payouts for our NEOs were paid above target as a result of our strong financial performance in 2025, including achievement of results above our financial targets.

2025 Summary

1 |  | CEO’s Successful Leadership

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

|  |  |  |  |  |  |  |  |  |  |  | -  2026 Proxy Statement|27

##### Table of Contents

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.

2 |  | Financial Results

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:

• |  | Year-over-year revenue growth. End-market demand remained strong with net sales up ~28% (to ~$10.2 billion) versus prior year, and organic net sales growth(1) of 26%.

• |  | Very strong backlog. Backlog continued to be strong increasing to ~$15.0 billion at the end of December 2025, increasing ~109% versus prior year.

• |  | Increased investment in engineering, research and development. We continued to invest in new product development with ER&D spending of ~$442 million in 2025 (~4.3% of revenue).

• |  | Profitability. Full year net income was ~$1,333 million, operating profit was ~$1,830 million and adjusted operating profit(1) was ~$2,090 million. Full year 2025 operating margin was ~18% and adjusted operating margin was ~20%, an increase of ~1% versus prior year.

• |  | Inflation mitigation. The Company continued its efforts to manage and mitigate inflationary pressures and shortages in materials and labor in 2025 by continued focus on, and implementation of, supplier resiliency programs, alternative supplier qualifications and engineering redesign initiatives.

• |  | Adjusted free cash flow. 2025 net cash provided by operating activities was ~$2,114 million, an increase of ~$795 million (or 60%) versus the prior year. Adjusted free cash flow(1) for 2025 was ~$1,888 million, an increase of ~$753 million (or 66%) versus the prior year primarily driven by higher adjusted operating profit and benefits from working capital and other, offset by higher cash taxes. Liquidity(2) at the end of the fourth quarter 2025 remained strong at ~$2.6 billion, including ~$1.7 billion of cash, ~$0.1 million in short-term investments and $784 million of availability under the asset-based lending (ABL) facility.

• |  | Strong financial performance. 2025 was a continuation of the Company’s unwavering dedication and focus on operational excellence and execution, technology innovation and capacity growth and expansion, and high-performance culture, culminating in a historic financial performance across all of the Company’s financial metrics. While these are all indicators of growth, operational improvements and execution by the Company in 2025, we continue to strive to improve our Vertiv Operating System (VOS) across our organization to implement best practices and process improvements and efficiencies across our global organizations to more effectively and efficiently manage our business, our operations, and our costs while aiming to deliver short and long-term value for our stockholders.

(1) | See Annex A for reconciliations of and information regarding the non-GAAP metrics.

(2) | Liquidity is calculated as cash and cash equivalents, short-term investments, and availability under the ABL Revolving Credit Facility as of December 31, 2025.

3 |  | Commitment to Stockholders

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.

4 |  | Stockholder Return

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).

5 |  | Compensation Packages Strongly Aligned with Stockholder Interests

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.

(1) | Excludes our new CFO given his start date late in the year. Long-Term Incentive reflects equity awards actually granted during 2025, not any modifications, and does not include the one-time performance equity award to Mr. Armul.

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.

2025 CEO Compensation |  |  |
Base Salary (as of 12/31/25) |  |  | $ 1,300,000 |
Target Cash Bonus (as % of Base Salary) |  |  | 150% |
Actual Cash Bonus (for 2025 performance) |  |  | $ 4,000,000 |
Approximate Grant Date Fair Value of Annual Equity Awards Granted |  |  | $ 13.04 M |

6 |  | Continued Best Practices in Compensation

✓ | Robust stock ownership guidelines. We require executive officers and directors to hold meaningful amounts of stock and to meet these guidelines within five years of first becoming subject to the guidelines, as further described under “Stock Ownership Guidelines for Company Officers and Directors.” Further, the Company adopted a “no sale” restriction that restricts an executive officer from selling stock until such officer has met or exceeds ownership guidelines. All of our executive officers and directors have met or are on their way to meeting these guidelines within the applicable period.

✓ | Clawback policy. Under our clawback policy, our Board will seek to recover incentive compensation from an executive officer on a no-fault basis in the event of an accounting restatement as a result of the Company’s material non-compliance with any financial reporting requirement.

✓ | Prohibition of hedging and pledging. Our insider trading policy prohibits our officers, directors and employees from hedging or pledging our shares.

✓ | Alignment with stockholders’ interests. Our incentive program aligns with stockholder interests by heavily weighting incentives in favor of long-term equity awards. In particular, stock options are performance-based because they have value only if our stock price increases.

✓ | Emphasis on variable cash pay. A significant portion of our executives’ cash compensation opportunity was performance-based, tying to near-term objectives and actual performance that we believe align with long-term growth. The target bonus for our CEO for 2025 was 150% of salary so that more than half of the CEO’s target cash compensation is directly dependent upon performance. Our actual bonus payouts for 2025 reflected our strong financial performance as discussed above.

##### Table of Contents

✓ | Only “double-trigger” executive change-in-control benefits. We do not provide “single-trigger” change-in-control benefits to executive officers; instead, we only provide “double-trigger” benefits, which generally means the executive needs to have a qualifying termination event (e.g., termination without cause or resignation by the executive for good reason) to receive a change-in-control benefit.

✓ | No 280G gross-ups. We have not agreed to provide our executive officers, including any NEO, with a “gross-up” or other reimbursement payment for any tax liability that he or she might owe as a result of the application of Section 280G (related to a change-in-control) of the Code.

✓ | Use of peer group data. Our Compensation Committee has developed and updated a peer group to provide an additional measure of comparison in its review of compensation.

✓ | Avoid excessive risk taking. Based upon a risk assessment, our Compensation Committee determined that our compensation policies do not encourage excessive or unnecessary risk-taking.

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.

Compensation Philosophy and Process
The Compensation Committee is focused on maintaining an executive compensation program that emphasizes
variable, at-risk compensation
and has an appropriate balance of short-term and long-term objectives.
Executive compensation is approved by the Compensation Committee, which consists solely of independent directors, and then the Board (with all of the independent members of the Board) approves the CEO’s compensation. Our Compensation Committee meets
regularly
throughout the year to review our executive compensation program and to ensure alignment of the interests of our executives with those of our stockholders. Meeting agendas contain items proposed by management or the Compensation Committee members.
Our Compensation Committee members engage in active discussions of
compensation
matters with management and with each other as part of their decision-making process. Each meeting includes an executive session with only the independent directors. On at least an annual basis, the Compensation Committee reviews relevant market data using a peer group representing a set of companies in the industries (mix of industrial and network equipment and services companies) in which we compete. For further information about our process, see “
Peer Group Companies
” below.
Equity Grant Timing Policy
Pursuant to our Equity Grant Policy, implemented at the February 24, 2021, meeting of the Compensation Committee, annual equity awards to directors and continuing executive officers are to be approved at the first meeting of the Compensation Committee (and, where applicable, the Board) held during the first quarter of the year. Additional grants (such as promotion, new hire or special grants) may be approved during the year. Under our 2020 Stock Incentive Plan, the Compensation Committee may delegate authority to our CEO to make grants
to non-executive e
mploy
ees,
but may not delegate any authority with respect to grants to executive officers.
Components of Compensation for 2025

1 |  | Base Salary

Base salaries generally take into account each named executive officer’s existing pay as well as the executive’s position, responsibilities, qualifications, experience and location, the market for the position, the base salaries of other executive officers and the Company’s overall financial performance.
The Compensation Committee considers base salary as one component of a total compensation package that needs to be balanced appropriately for each named executive officer. In March 2025, the Compensation Committee approved an increase in Mr. Albertazzi’s base salary from $1,100,000 to $1,300,000, together with an increase in target bonus percentage, primarily to reflect his successful leadership, as reflected in Vertiv’s record results for 2024, as well as successful execution of strategic imperatives in M&A, technology innovation, high performance culture, manufacturing and capacity expansion and capabilities, and operational execution. The increases in Mr. Albertazzi’s total compensation (including equity compensation) also reflected the consideration that given his successful performance since his promotion, it was important to reflect total compensation commensurate closer to or above the median in our Compensation Peer Group. Other increases for the NEOs were based on similar considerations including their individual roles and responsibilities. Mr. Chamberlin’s initial compensation was agreed pursuant to his offer letter, which involved considerations around peer group
data
, experience, skill sets, incentives to relocate and take the role, and amounts needed to offset
lost
compensation opportunities.
The table below shows the annualized base salaries in effect at the end of 2025.

|  | Base Salary at 12/31/25 ($) |
Albertazzi |  |  | 1,300,000 |
Chamberlin |  |  | 750,000 |
Sanghi |  |  | 535,000 |
Gill |  |  | 580,000 |
Armul |  |  | 480,000 |

2 |  | Vertiv Annual Incentive Plan

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.

• |  | Financial Performance Goals. In early 2025, the Compensation Committee approved Adjusted Operating Profit (“AOP”) and Adjusted Free Cash Flow (each as defined below) as financial metrics (and, where applicable, for regions and segments) for purposes of bonuses under the VIP. At that time, the Compensation Committee determined that it was also appropriate to retain the ability to take into account individual and other business performance measures in approving the final individual payout level.

• |  | Financial Performance Results. In early 2026, the Compensation Committee reviewed our financial results against the previously approved financial metrics established for purposes of the 2025 VIP and against our prior year’s performance in determining an overall result of 135%.

| • |  | Results Significantly Above Challenging Targets. As shown in the table below, our AOP results of approximately $2,090 million and Adjusted Free Cash Flow of approximately $1,888 million significantly exceeded the target levels for each metric set for purposes of the VIP, which had been set as very challenging goals that exceeded our 2024 actual performance levels, which were our highest results to date.

| • |  | Results Exceeding Prior Year Results. Our results for 2025 reflected tremendous improvement over 2024, resulting in a year over year increase of approximately 35% in AOP and 66% in Adjusted Free Cash Flow.

| • |  | Other Financial Performance Considerations. Our historic financial performance also included a significant increase in backlog at year end 2025 to $15,000 million, and a year over year increase of approximately $2,218 million in net sales and approximately $1.35 in adjusted diluted earnings per share, as well as transformative operational execution and growth in our business as described above under “2025 Summary-Financial Results” above.

• |  | Segment Financial Performance Results. For our NEOs other than the CEO, the Compensation Committee also reviewed the performance of the individual’s segment (that is, region, function or lines of business) where they have responsibility. For Mr. Sanghi, a portion of his bonus reflected how the relevant region (the Americas) performed relative to the same types of financial targets as for the overall goals described above which resulted in an increased payout due to strong regional performance.

• |  | Individual Performance Modifier. The Compensation Committee finally considered individual performance based on individual impact to the results of their assigned segment or corporate function. In approving the individual performance factors for our NEOs (other than our CEO), the Compensation Committee focused on recognizing the efforts of individuals who were directly responsible for successful operational execution and performance against the Company’s strategic initiatives in particular regions, functions or lines of business. The Committee recognized that Mr. Sanghi drove tremendous acceleration in his second year in the role of President, Americas, establishing the Americas as a primary growth engine, and he led the successful implementation of the systems approach, including SmartRun and OneCore, alongside benchmark-setting sales execution. The Committee believed that these efforts, combined with the strong financial results for the Americas being significantly higher than overall results, merited a payment above the 200% maximum, resulting in the actual payout set forth below. The Committee also approved individual performance modifiers that increased the bonus payment for other NEOs. Ms. Gill’s modifier reflected her leadership in the development, implementation, and improvement of various corporate legal and business-related programs and processes, such as commercial contracting initiatives, strategic acquisitions, compliance and governmental relations program, and enhancements of our environmental, health and safety program and intellectual property program, that resulted in significant operational improvements and efficiencies and cost reductions and savings. Mr. Armul’s modifier reflected his strong performance in his first year in the role, leading improvements across our technology and innovation development initiatives, advanced research and engineering programs, and product and service offerings, showing an ability to translate strategy across disciplines, and aligning the innovation agenda with Vertiv’s short and long-term needs to meet growing customer demands.

| • |  | CEO Performance. In determining the payout level for our CEO, the Compensation Committee recognized his leadership in guiding us through a year of unprecedented AI and high performance compute adoption, data growth and technology innovations, and the direct impact his strong leadership and focus had on our strategic operational and financial performance. In particular, he led with conviction and was resolute on delivering operational execution and excellence in all areas, particularly strategic acquisitions that enhanced our product and service offerings, technology innovation across our business units, manufacturing and capacity expansions and increased capabilities, supply chain resilience, and other key operations initiatives.

##### Table of Contents

• |  | Bonus Payment Details. The table below shows the annual target bonus opportunities for 2025 for each of the named executive officers and the actual payout. The target cash bonus levels (as a percentage of salary at year-end) were set to reflect the executive’s relative responsibility for the company’s performance and to appropriately allocate the total cash opportunity between base salary and variable incentive-based compensation. Amounts paid to any individual executive officer may range from 0% to 200% of target (or above 200% if approved by the Committee under extraordinary circumstances). As described above, for 2025, the Committee approved an increase in the maximum for each of Mr. Albertazzi and Mr. Sanghi to reflect the exceptional Company, functional and individual performance.

|  | Target Bonus (as % of Salary) |  | Target Bonus ($) |  | Earned Bonus (as approx. % of Target) |  | Earned Bonus ($)(1)
Albertazzi |  |  |  | 150 | % |  |  |  | 1,950,000 |  |  |  |  | 205 | % |  |  |  | 4,000,000 |
Chamberlin(2) |  |  |  | N/A |  |  |  |  | N/A |  |  |  |  | N/A |  |  |  |  | N/A |
Sanghi |  |  |  | 80 | % |  |  |  | 428,000 |  |  |  |  | 257 | % |  |  |  | 1,100,000 |
Gill |  |  |  | 75 | % |  |  |  | 435,000 |  |  |  |  | 195 | % |  |  |  | 850,000 |
Armul |  |  |  | 70 | % |  |  |  | 336,000 |  |  |  |  | 149 | % |  |  |  | 500,000 |
Fallon |  |  |  | 100 | % |  |  |  | 690,000 |  |  |  |  | (3) |  |  |  |  | 837,074 |

(1) | Amounts were subject to rounding.

(2) | Mr. Chamberlin was not eligible for a 2025 VIP bonus, but pursuant to his offer letter, received a $300,000 sign-on bonus.

(3) | Mr. Fallon received a pro-rated bonus for 2025 under his Transition Agreement based solely on the financial results.

Corporate Financial Results

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

Global Plan Metric |  | 2024 Actual |  | 2025 VIP Target |  | 2025 Actual
Adjusted Operating Profit(1) |  |  | $ | 1,552M |  |  |  | $ | 2,050M |  |  |  | $ | 2,090M |
Adjusted Free Cash Flow(2) |  |  | $ | 1,135M |  |  |  | $ | 1,400M |  |  |  | $ | 1,888M |

(1) | Adjusted Operating Profit was chosen as an important measure of near-term profitability which in turn creates stockholder value. Adjusted Operating Profit represents the Company’s operating profit, adjusted to exclude the amortization of intangibles, restructuring costs – global programs, contingent consideration and certain mergers and acquisition costs. See Annex A for a reconciliation of and information regarding this non-GAAP metric.

(2) | Adjusted Free Cash Flow was chosen because it reflects cash generated from operations that may be reinvested in our businesses or returned to stockholders. Adjusted Free Cash Flow represents net cash provided by (used for) operating activities adjusted to excluded capital expenditures and investments in capitalized software. See Annex A for a reconciliation of and information regarding this non-GAAP metric.

3 |  | Long-Term Incentive Compensation

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:

• |  | Stock options provide the most direct tie to shareholder value realization.

• |  | The ultimate value of the options will align directly with our stockholders’ return through our stock price performance, which in turn depends on our sustainable operational and financial performance, thereby discouraging excessive risk-taking and encouraging operational execution and continual process improvements to drive efficiencies within our operating systems.

• |  | The stock options only have value to the executive if the stock price increases after the grant date, meaning both management and the stockholders benefit.

• |  | We benefit from the retention value provided through multi-year vesting and long-term exercise period.

• |  | The stock options offer complementary incentives to our annual bonus plan, which is based on financial metrics that are set annually, and the cash bonus opportunities already represent a meaningful portion of target compensation.

• |  | The stock options also offer complementary incentives to the Strategic Performance Awards that were previously granted, which are full-value awards but will only become earned and vested if we exceed pre-specified financial goals.

• |  | Stock options tie to absolute rather than relative value, which is appropriate because our focus is on the benefit to our stockholders.

##### Table of Contents

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.

Fiscal Year |  | Target AOP |  |  | Actual AOP |  |  | Percentage of Tranche Earned |
2023 |  |  | $1,000M |  |  |  | $1,054M |  |  |  | 120 | %
2024 |  |  | $1,400M |  |  |  | $1,552M |  |  |  | 160 | %
2025 |  |  | $1,750M |  |  |  | $2,089M |  |  |  | 220 | %

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 Strategic Performance Awards are settled in shares of our stock to align the management team’s interests in stock price appreciation with the interests of our stockholders.

• |  | Determination of whether a Strategic Performance Award target is met is done on a purely formulaic basis related to our financial results.

• |  | No amount was earned for any year (including 2025) unless Target AOP was met.

• |  | We benefit from the retention value provided through cliff-vesting by requiring employment through January 1, 2027 before any amount would vest.

• |  | Earned award values were determined annually over a three-year performance cycle to align with long-term financial objectives.

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

• |  | AOP is an important metric because it reflects our operational performance, and our stockholders view it as a key metric for value creation.

• |  | The performance levels chosen in late 2022 were intentionally set to be challenging. For example, the goal for 2023 performance was more than twice our actual 2022 results, and the goals for each subsequent year were significantly greater than the target for the prior year. We believe that the actual earned amounts are reflections of our strong performance over this time period.

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 (target EPS of $6.25),

• |  | 2027 (target EPS of $8.15), and

• |  | 2028 (target EPS of $10.55).

|  |  |  |  |  |  |  |  |  |  |  | -  2026 Proxy Statement|35

##### Table of Contents

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.

(1) | EPS targets are not adjusted for M&A, share repurchases, etc.

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.

4 |  | Retirement Benefits

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.

5 |  | Termination and Change-in-Control Benefits

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.

6 |  | Other Benefits

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.

Position |  | Multiple for Stock Ownership Guidelines
Directors |  | 5 times Cash Retainer
Chief Executive Officer |  | 5 times Salary
NEO |  | 3 times Salary
Other Section 16 Officers (reporting to the CEO) |  | 2 times Salary
Other Section 16 Officers (not reporting to the CEO) |  | 1 times Salary

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

##### Table of Contents

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.

(1) | Name and Principal Position. Mr. Chamberlin was hired as CFO on November 10, 2025.

(2) | Equity Grants. The amounts reported in the Option Awards column represent the aggregate grant date fair value of stock options granted in the relevant fiscal year. Assumptions used in calculating these amounts are described in Note 14 to our audited financial statements in our Form 10-K for the year ended December 31, 2025, filed with the SEC. Also see the table entitled “Grants of Plan Awards in Fiscal 2025” below for further information regarding grants made during 2025. The amount for Mr. Fallon also includes $247,701 as a result of the modification of his outstanding options as described in the “Compensation Discussion and Analysis” above. The amounts reported in the Stock Award column generally represent the Strategic Performance Awards granted in the applicable year, valued at target. The amount reported for Mr. Chamberlin in the Stock Award column for 2025 represents RSUs granted in connection with his hiring.

(3) | Annual VIP. The amounts reported in this column for 2025 reflect payments under the 2025 VIP, as described in the “Compensation Discussion and Analysis” above. Mr. Chamberlin was not eligible for the 2025 VIP because of his November 2025 start date, but received a cash sign-on bonus, as reported in the Bonus column. Mr. Fallon received a pro-rated payment for the period he served as CFO.

(4) | Other Benefits. The amounts shown in this column represent other compensation, including the cost of personal benefits or perquisites (but may exclude those that are less than $10,000 in the aggregate). We maintain arrangements with third-party charter companies for use of chartered aircraft, used primarily for business purposes. If there is personal aircraft usage reported in this table, the amount is based on Vertiv’s actual invoiced amount from the charter company for the variable costs incurred on each trip. Because the aircraft is used primarily for business travel, this methodology excludes fixed costs that do not change based on usage, such as depreciation and management fees. To the extent an NEO’s spouse or guests accompany the officer when a flight is already going to a specific destination for a business purpose, there is no reported value in the table where there is no aggregate incremental cost to Vertiv.

| (a) | Giordano Albertazzi. The amount for 2025 reflects travel-related expenses.

| (b) | Craig Chamberlin. The amount for 2025 reflects (i) relocation benefits, consisting of $6,466 for temporary housing and $2,685 for tax reimbursement on the foregoing, and (ii) $10,500 in Company contributions to applicable retirement plans.

| (c) | Anand Sanghi. The amount for 2025 reflects (i) $10,088 in Company contributions to applicable retirement plans and (ii) as a result of his accepting a U.S.-based role, tax equalization amounts of $231,242 and tax preparation fees of $1,000.

| (d) | Stephanie Gill. The amount for 2025 reflects Company contributions to our 401(k) plan.

| (e) | Scott Armul. The amount for 2025 reflects Company contributions to our 401(k) plan.

| (f) | David Fallon. The amount for 2025 reflects Company contributions to our 401(k) plan.

Understanding Our Summary Compensation Table and Grants of Plan-Based Awards in Fiscal 2025 Table

Employment Arrangements. Our Executive Employment Policy and our Executive Change of Control Plan generally cover our named executive officers. Vertiv’s named executive officers are subject to confidentiality, non-compete and non-solicitation covenants. See “Potential Payments Upon Termination or Change in Control” below for a description of the post-termination provisions in these arrangements.

Annual Cash Incentive Plan. During 2025, Vertiv maintained the VIP, pursuant to which cash incentive awards may be made to the named executive officers and other eligible employees based on 2025 performance. Executive officers generally must be employed by the Company at the time of payout under the VIP to be eligible for an award. For a summary of the VIP and the determination of payouts for 2025 performance, see the “Compensation Discussion and Analysis” above.

Equity Awards. Our equity awards were granted under, and are governed by and subject to, the terms and conditions of the 2020 Stock Incentive Plan and the relevant award agreements. As described above, during 2025, all of our NEOs were granted stock options. A description of treatment of equity awards on termination of employment is included under “Potential Payments Upon Termination or Change in Control” below.

Retirement Plans and Other Benefits. Vertiv maintains retirement benefit plans, including a 401(k) plan for U.S. employees, and provides the named executive officers with benefits and perquisites. Also see the “Compensation Discussion and Analysis” above.

(3) | The amounts listed for RSUs include dividend equivalents accrued under the terms of the award agreements in the form of additional RSUs, which vest over the same schedule as the underlying RSUs. Pursuant to the terms of the 2020 Stock Incentive Plan, fractional shares are required to be settled in cash upon vesting.

The actual value realized by the executive officer will depend on whether the award vests and the future stock price performance.

(5) | Represents the dollar value actually earned under the Strategic Performance Awards through the final performance period that ended December 31, 2025. In February 2026, these dollar values were converted into RSUs (with the number of shares determined by dividing this amount by our stock price on such date) that will vest on January 1, 2027, subject to continued employment, with limited exceptions related to death, disability, and change in control termination.

(6) | These RSUs vest in installments of 50% on November 15, 2026, 30% on November 15, 2027, and 20% on November 15, 2028.

(7) | Each of these RSUs were granted with a vesting schedule in three equal installments on the third, fifth and seventh anniversaries of the grant date.

Potential Payments Upon Termination or Change in Control

Executive Employment Policy, Award Agreements and Other Agreements

Severance Benefits. Under the Executive Employment Policy, if a named executive officer’s employment is terminated without cause or by the executive for good reason (each as defined in the Executive Employment Policy), then in addition to accrued obligations through the termination date, provided that the named executive officer executes and does not revoke a release, each named executive officer shall be eligible for the following severance benefits:

(i) | a cash payment equal to one times the executive’s annual rate of base salary immediately prior to the termination of employment, to be paid in installments over 12 months in accordance with our normal payroll policies;

(ii) | a cash payment equal to one times the executive’s target annual bonus, to be paid in installments over 12 months in accordance with our normal payroll policies, or, for individuals who become subject to the Employment Policy after 2023, a pro-rated target bonus;

(iii) | any earned and unpaid annual bonus for the fiscal year preceding the fiscal year in which the termination occurs; and

(iv) | reimbursement of COBRA continuation coverage costs for 12 months.

Each named executive officer is subject to standard restrictive covenants, including non-competition and non-solicitation covenants for 12 months.

If an executive’s employment is terminated by reason of the executive’s death or disability, then in addition to accrued obligations through the termination date, Vertiv shall pay to the executive or the executive’s beneficiary or estate, as the case may be, (i) any earned and unpaid amounts owed under the VIP for the fiscal year preceding the fiscal year in which the termination date occurs and (ii) a pro-rata portion of the executive’s compensation under the VIP for the fiscal year in which the termination date occurs, subject to the achievement of applicable performance measures and paid at the same time as amounts are paid to other executives generally.

Equity Award Provisions. The RSU agreements for RSUs granted prior to 2024 to individuals who were executive officers at the time of grant provide that, upon a termination without cause by Vertiv, any unvested RSUs scheduled to vest during

42| |  |  |  | -  2026 Proxy Statement |  |  |  |  |  |

##### Table of Contents

the six-month period following termination shall vest on the applicable scheduled vesting dates. In addition, the RSU and option agreements provide that the awards will vest in full upon termination of employment due to death or disability and remain eligible for continued vesting upon retirement from active employment on or after age 65 with 10 years of service.

The Strategic Performance Award agreements provide that the awards will be forfeited upon a termination of the executive’s employment prior to the January 1, 2027 vesting date, with limited exceptions. If the executive’s employment is terminated due to death or disability, the earned portion for any completed years of the performance period will become vested, with remaining unearned portions forfeited. Treatment on a change in control is described below.

Change of Control

The Executive Change of Control Plan (“CIC Plan”) provides “double-trigger” severance benefits to senior employees, including the named executive officers, upon specified terminations of employment from Vertiv in connection with a change of control of Vertiv (as defined in the CIC Plan). In the event of a change of control, the executive must also either (i) be involuntarily terminated other than for cause (as defined in the CIC Plan) or (ii) initiate the termination of his or her own employment for good reason (as defined in the CIC Plan). Additionally, either qualifying termination event must occur during the period that starts 90 days immediately prior to the change of control and ends 24 months following such change of control (“Change of Control Period”).

If such termination occurs during the Change of Control Period, the executive would be entitled to:

(i) | lump-sum cash payments equal to a multiplier of two (or, in the case of the CEO at the time of a change in control, three) times the sum of (x) then current base salary and (y) annual target bonus;

(ii) | a lump-sum cash payment equal to the executive’s annual target bonus during the fiscal year of termination, pro-rated based on the number of days worked by the executive during such fiscal year;

(iii) | a lump-sum cash payment equal to the executive’s actual bonus accrued in the fiscal year prior to the year of termination, but not yet paid;

(iv) | full vesting on an accelerated basis of any of the executive’s unvested long-term incentive awards; and

(v) | COBRA continuation coverage for 18 months.

With respect to the Strategic Performance Awards, in the event of the foregoing qualifying termination, or if the awards are not assumed or replaced by the acquiror, (i) the earned portion of any Strategic Performance Award for completed years and (ii) the target amount of any Strategic Performance Award for incomplete years, will immediately vest.

The CIC Plan does not provide executives with an excise tax gross-up. Instead, to the extent that the payment and benefits to be provided under the CIC Plan or other Company plan or agreement would be subject to the excise tax imposed under Section 4999 of the Internal Revenue Code on excess parachute payments within the meaning of Section 280G of the Internal Revenue Code, the payments will be reduced to the extent necessary so that no portion will be subject to the excise tax if, with such reduction, the net after-tax benefit received by the executive exceeds the net after-tax benefit that would be received by the executive if no such reduction was made. The CIC Plan contains certain confidentiality, non-competition and non-solicitation covenants in favor of the Company.

Potential Payments Upon Termination of Employment

The table below reflects the amount of compensation and benefits payable to each named executive officer in the event of a (i) termination without cause, (ii) termination for good reason, (iii) termination under the CIC Plan, (iv) termination by reason of the executive’s death or disability, or (v) upon retirement. The amounts shown assume that the applicable triggering event occurred on December 31, 2025 and, therefore, are estimates of the amounts that would be paid to the named executive officers upon the occurrence of such triggering event. Mr. Fallon is not included because his employment ended in November 2025, and his Transition Agreement is described in the Compensation Discussion and Analysis above.

(1) | Our RSU agreements granted to individuals prior to 2024 who were executive officers at the time of grant provide that, upon a termination without cause, any unvested RSUs scheduled to vest during the six-month period following termination shall vest on the applicable scheduled vesting dates. In addition, our RSU and option agreements provide that the awards vest in full upon termination of employment due to death or disability and remain eligible for continued vesting upon retirement at age 65. As of December 31, 2025, none of the NEOs met the definition of retirement under these agreements. Under the CIC Plan, all RSUs and options fully accelerate upon a qualifying termination during a Change in Control Period. The treatment of the Strategic Performance Awards in the event of a change in control is described above. The value in this column was calculated by multiplying the number of unvested awards as of December 31, 2025 by $162.01, which was the closing price of our Class A common stock on December 31, 2025, the last trading day of the fiscal year, less, in the case of stock options, the applicable exercise price. The value of the Strategic Performance Awards in this table reflects the actual earned value as of December 31, 2025.

(2) | Pursuant to the Executive Employment Policy, consists of (i) a cash payment equal to one times the sum of the executive’s annual rate of base salary as in effect on December 31, 2025 and target annual bonus for 2025 (or, if applicable, a pro-rated target bonus) and (ii) if applicable, the estimated cost of health coverage for 12 months. Amounts payable upon resignation or retirement in this table exclude accrued benefits under the Company’s retirement plans.

(3) | Pursuant to the CIC Plan, consists of (i) lump-sum cash payments equal to a multiplier of two (or, in the case of the CEO, three) times the sum of (x) base salary in effect on December 31, 2025 plus (y) target annual bonus for 2025; (ii) a lump-sum cash payment equal to the executive’s annual target bonus during the fiscal year of termination, pro-rated based on the number of days worked by the executive during such fiscal year (so 100% of annual target bonus for a termination on December 31, 2025); and (iii) the estimated cost of health coverage for 18 months.

(4) | Pursuant to the Executive Employment Policy, payment on death or disability would be a pro-rated portion of the executive’s annual bonus for the fiscal year in which the termination date occurs (so 100% for a termination on December 31, 2025). Each NEO’s actual 2025 bonus is reflected in this table.

CEO Pay Ratio

As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC adopted a rule requiring companies to disclose the ratio of the median employee’s total annual compensation relative to total annual compensation of the principal executive officer.

As permitted under SEC rules, the Company determined that it was appropriate to use the same median employee (the “Median Employee”) used in the disclosure for the prior year based on its reasonable belief that the increase in the employee population since such date would not result in a significant change to its pay ratio disclosure. The median employee was identified by examining the Company’s compensation records to calculate each employee’s cash compensation opportunities during the applicable year. The review included all employees employed by the Company as of December 1, 2024, which consisted of 30,562 employees (excluding our CEO). After identifying the median employee, we calculated an estimate of the total annual compensation for 2025 for such employee, using the same methodology used for our NEOs as set forth in the Summary Compensation Table above. As a global organization, most of our employees are located outside of the United States, including the median employee.

We used the following additional methodology and material assumptions:

• |  | Pay was annualized for employees who worked a partial year.

• |  | Foreign currencies were converted into U.S. dollars.

Total compensation for 2025 for Mr. Albertazzi was $18,311,719. Our median employee’s estimated total compensation for 2025 was $27,811. Therefore, the ratio of our 2025 principal executive officer’s pay to our median employee’s pay for 2025 is 658:1.

Pay versus Performance
As required by Item 402(v) of Regulation
S-K,
we are providing the following information regarding the relationship between executive compensation and our financial performance for each of the last four completed calendar years. In determining the “compensation actually paid” (“
CAP
”) to our NEOs, we are required to make various adjustments to amounts that have been previously reported in the Summary Compensation Table in previous years, as the SEC’s valuation methods for this section differ from those required in the Summary Compensation Table.

(1) | The dollar amounts reported in these columns are, respectively, (x) the amounts of total compensation reported for our Principal Executive Officer (“ PEO ”) and (y) the average of the amounts reported for the Company’s non-PEO named executive officers (“ Non-PEO NEOs ”) as a group, in each case as set forth in the “Total” column of the Summary Compensation Table for each applicable year. Our PEO was Mr. Albertazzi for 2025, 2024 and 2023 and Rob Johnson for each of 2022 and 2021. For purposes of calculating the average amounts in each applicable year, the names of each of the Non-PEO NEOs are as follows: Giordano Albertazzi (2022), Craig Chamberlin (2025), Scott Armul (2025), David Fallon (2025, 2024, 2023, 2022, 2021), Stephen Liang (2023, 2022, 2021), Anand Sanghi (2025, 2024, 2023), Anders Karlborg (2024, 2023), Phil Doherty (2022), Stephanie Gill (2025, 2024, 2021), and Jason Forcier (2021).

(2) | The dollar amounts reported in these columns represent the amount of “compensation actually paid” in the applicable fiscal year, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments set forth below were made to the total compensation for each year to determine the compensation actually paid. Adjusted fair values have been determined using, as applicable, updated stock price and assumptions (i.e., term, volatility, dividend yield, risk free rates) as of the measurement date.

Fiscal Year 2025 |  | PEO($) |  |  | Non-PEO NEOs($) |
Total from Summary Compensation Table |  |  | 18,311,719 |  |  |  | 2,462,002 |

Compensation Actually Paid |  |  | 102,015,794 |  |  |  | 6,115,522 |

(3) | Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period. Peer group TSR shown in the table was based on the index we use for purposes of Item 201(e)(1)(ii) of Regulation S-K. If we used the Compensation Peer Group (with the list of companies provided in the “ Compensation Discussion and Analysis ” above), the peer group weighted TSR for the measurement periods shown in the table would have been 224.6, 158.6, 138.1, 112.6 and 141.5 at the end of 2025, 2024, 2023, 2022 and 2021, respectively.

(4) | Dollar amounts reported represent (i) the amount of net income reflected in the Company’s audited financial statements for the applicable year and (ii) the amount of adjusted operating profit ( “AOP ”), which is a non-GAAP measure we used under the VIP for 2025. For an explanation and reconciliation of AOP, please see Annex A.

Performance Measures.
Listed below are the financial
and non-financial performance
measures which in our assessment represent the most important financial performance measures we use to link compensation actually paid to our named executive officers, for 2025, to Company performance.

Measure |  | How We Used the Measure
Adjusted Operating Profit (AOP) |  | Metric in VIP and Strategic Performance Awards
Adjusted Free Cash Flow |  | Metric in VIP
Stock Price |  | Used to determine exercise price of stock options and ultimate realized value of all equity awards

Relationship Between Pay and Performance.
“Compensation actually paid” (
“CAP
”), as required under SEC rules, reflects adjusted values to unvested and vested equity awards during the years shown in the table based on stock prices
at year-end, various
accounting valuation assumptions and other adjustments, but does not reflect actual amounts realized on those awards. CAP generally fluctuates primarily based on stock price, even for equity awards that will not vest until a future year. As a result, CAP may have a relationship to TSR and our performance against peer group TSR. Although AOP is a metric in our annual VIP cash bonuses, it may have less of a relationship to CAP because of the impact of stock price on equity award valuations. Net income is not a metric currently used in our compensation program. For a discussion of how our Compensation Committee assessed Company performance and our named executive officers’ compensation, see “
Compensation Discussion and Analysis
” elsewhere in this proxy statement. See the graphs below for further information on the relationship between CAP and performance.

Proposal 2: |  | Advisory Vote to Approve Compensation of Named Executive Officers

In accordance with the requirements of Section 14A of the Exchange Act and Exchange Act Rule 14a-21(a), we are including in this proxy statement a separate resolution to approve, in a non-binding, stockholder advisory vote, the compensation paid to our named executive officers as disclosed in “Executive Compensation” above. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific item of compensation or any specific named executive officer, but rather the overall compensation of all of our named executive officers and the philosophy, policies and practices described in this proxy statement.

The Board believes that our executive compensation programs align the interests of stockholders and executive officers by emphasizing variable, at-risk compensation through a combination of long-term equity incentives and annual cash incentives. We encourage you to read the disclosure under “Compensation Discussion and Analysis” to learn more about our executive compensation programs and policies. The Board believes that our 2025 executive compensation program shows alignment between the interests of our executives and stockholders.

While the results of the say-on-pay vote are non-binding and advisory in nature, our Board of Directors and Compensation Committee intend to consider the results of this vote in making future compensation decisions.

We expect that our next advisory say-on-pay vote will take place at our annual meeting of stockholders in 2027.

Proposal 3: |  | Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit Committee has appointed Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Ernst & Young LLP has served as the Company’s independent registered public accounting firm since the consummation of the Business Combination in 2020 and previously served as principal accountants to the Vertiv operating business from 2016 until their dismissal in 2020 in connection with the Business Combination. Stockholder ratification of the appointment of Ernst & Young LLP is not required by law. The ratification of the appointment of Ernst & Young LLP requires the affirmative vote of a majority of the votes cast by stockholders present in person or represented by proxy and entitled to vote thereon at the Annual Meeting. If the stockholders do not ratify the appointment of Ernst & Young LLP, the Audit Committee will reconsider the appointment. Even if the stockholders ratify the appointment of Ernst & Young LLP, the Audit Committee retains the discretion to appoint a different independent registered public accounting firm at any time if it determines that such a change would be in the best interests of Vertiv and its stockholders. Ernst & Young LLP is knowledgeable about our operations and accounting practices and well qualified to act as our independent registered public accounting firm, and the Audit Committee has appointed it as such for fiscal 2026.

Representatives of Ernst & Young LLP are expected to attend the Annual Meeting, will have an opportunity to make a statement if they desire to do so and are expected to be available to respond to appropriate questions.

Our Board of Directors recommends that you vote “FOR” the ratification of Ernst & Young LLP as our independent auditor for the fiscal year ending December 31, 2026.

INFORMATION REGARDING INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Ernst & Young LLP has served as the Company’s independent registered public accounting firm since the consummation of the Business Combination in 2020 and as principal accountants to the Vertiv operating business prior to the Business Combination since 2016.

The Audit Committee has the discretion to appoint a different independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in the best interest of the Company and our stockholders.

Pre-Approval Policy

The policy of our Audit Committee is to review in advance, and pre-approve all audit or non-audit services to be provided by the Company’s independent or other registered public accounting firm and to approve all related fees and other terms of engagement.

All non-audit services provided subsequent to our initial public offering in 2018 were reviewed with the Audit Committee, which in each case concluded that the provision of such services by the relevant independent registered public accounting firm was compatible with the maintenance of that firm’s independence in the conduct of its auditing functions.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Related Party Transactions Policies and Procedures

We have adopted a written policy on transactions with “related persons,” defined in the policy as a director, executive officer, nominee for director, or greater than 5% beneficial owner of any class of the Company’s voting securities, and their immediate family members.

For purposes of this policy, a “related person transaction” is defined as any transaction, arrangement or relationship in which the Company is a participant, the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person had, has or will have a direct or indirect material interest.

The Board of Directors, acting through those members of its Audit Committee who are not interested in the transaction in question, will review related person transactions to determine whether the related person transaction is in, or is not inconsistent with, the best interests of the Company and its stockholders. If, after any such review, a related person transaction is determined to be in, or not inconsistent with, the best interests of the Company, then the related person transaction may be approved or ratified according to the procedures in the policy. If advance Audit Committee approval of a related person transaction requiring the Audit Committee’s approval is not practicable or desirable, then the chair of the Audit Committee may approve or ratify a related person transaction.

In addition, the policy provides standing pre-approval for certain types of transactions that the Audit Committee has reviewed and determined shall be deemed pre-approved.

Business Combination

On February 7, 2020 (“Closing Date”), Vertiv consummated its business combination (“Business Combination”) with GS Acquisition Holdings Corp (“GSAH”), pursuant to an arrangement and plan of merger (“Merger Agreement”) by and among the Company, GSAH, Vertiv Holdings, LLC, a Delaware limited liability company (“Vertiv Holdings”), VPE Holdings, LLC, a Delaware limited liability company (“Vertiv Stockholder”), and Crew Merger Sub I LLC and Crew Merger Sub II LLC, each a Delaware limited liability company and a direct, wholly owned subsidiary of GSAH. In connection with the Business Combination, GSAH changed its name to “Vertiv Holdings Co” and changed the trading symbols for its units, each unit representing one share of Class A common stock and one-third of one redeemable warrant to acquire one share of Class A common stock, that were issued in the initial public offering of GSAH. As a result of the Business Combination, we became the owner, directly or indirectly, of all of the assets of the pre-Business Combination Vertiv Holdings, LLC and its subsidiaries, and the Vertiv Stockholder acquired a portion of our Class A common stock. On January 19, 2021, the Company redeemed the outstanding public warrants in full and the units and the Company’s public warrants were subsequently delisted from NYSE.

Other Related Party Transactions

Indemnification Agreements

Our standard form of indemnification agreement for each of our executive officers and directors provides, in general, that we will indemnify them to the fullest extent permitted by law in connection with their service to us or on our behalf.

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Exchange Act requires our officers, directors and persons who beneficially own more than 10% of our Class A common stock (the “10% Stockholders”) to file reports of ownership and changes in ownership with the SEC. These reporting persons are also required to furnish us with copies of all Section 16(a) forms they file. The Company’s executive officers, directors and 10% Stockholders timely complied with all such filing requirements applicable to them last fiscal year with respect to their beneficial ownership of the Company’s securities. We are not aware of any late or delinquent filings for the current fiscal year, except that a Form 4 reporting an award of restricted stock units to Eric Johnson was filed late on March 30, 2026 due to an administrative oversight.

Annex A |  | Non-GAAP Financial Measures

Certain financial information included in this proxy statement, as well as the letter to shareholders and annual report accompanying this proxy statement, are considered to be non-GAAP financial measures. Such measures, as further described below, may not be directly comparable to other similarly titled measures used by other companies and therefore may not be comparable among companies. Management believes these non-GAAP financial measures provide investors with useful supplemental information to evaluate the Company’s ongoing operations and to compare with past and future periods. Management also uses certain non-GAAP measures internally for forecasting, budgeting and measuring its operating performance. These measures should be viewed as supplementing, and not as an alternative or substitute for, the Company’s financial results prepared in accordance with GAAP. Pursuant to the requirements of Regulation G, Vertiv has provided reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures.

Vertiv’s non-GAAP financial measures include:

• |  | Adjusted operating profit (loss), which represents operating profit (loss), adjusted to exclude amortization of intangibles, restructuring costs associated with the global restructuring programs, contingent consideration, and merger and acquisition costs;

• |  | Adjusted operating margin, which represents adjusted operating profit (loss) divided by net sales;

• |  | Organic net sales growth, which represents the change in net sales adjusted to exclude the impacts of foreign currency exchange rate and acquisitions;

• |  | Adjusted free cash flow, which represents net cash provided by (used for) operating activities adjusted to exclude capital expenditures and investments in capitalized software; and

• |  | Adjusted diluted EPS, which represents diluted earnings per share adjusted to exclude amortization of intangibles, restructuring costs associated with global restructuring programs, contingent consideration, merger and acquisition costs, net non-recurring tax adjustments, term loan due 2032 amendment expense and change in warranty liability.
