Fellow Stockholders:

On behalf of the Board of Directors, we invite you to attend the SPX Corporation 2021 Annual Meeting of Stockholders on May 11, 2021, at 8:00 a.m. (Eastern Time). This year’s meeting will be held by a virtual format, conducted via live webcast.

2020 Review – A Solid Performance in a Challenging Year

2020 was a highly unusual and challenging year. Facing a worldwide pandemic, our team continued to make safety a top priority, while rapidly adapting and executing effectively on our value creation goals. Overall, our balanced portfolio and the resilience of our employees helped drive solid results. For the year, our adjusted revenue* increased 1.9% and adjusted earnings per share* rose 1.4%, making us one of only a small group of industrial companies to grow year-on-year. We are very proud of our accomplishments during 2020, including the introduction of several new products, progress on continuous improvement initiatives, the completion of two strategic acquisitions, and several valuable investments in our people and our culture.

Well Positioned to Continue Our Growth Journey

We entered 2021 in a very strong position. As we progress through this year, and beyond, we will continue to tightly adhere to our successful value creation framework. Our key initiatives include extending our continuous improvement processes across the organization, further investing in digital solutions to enhance our customers’ experience, and building on the successes in our employee development and Diversity & Inclusion efforts.

Environmental, Social & Governance is another important focus area for SPX. This year we will publish our fourth annual sustainability report detailing metrics on our water and energy usage, greenhouse gas emissions, and employee safety data. Our company offers a wide array of highly efficient and innovative products that position us to thrive in a world where long-term targets on carbon emissions are realized.

As we look to further build on the attractive growth platforms we have developed, we anticipate additional opportunities to employ our strong balance sheet and cash generation to invest in highly strategic businesses to accelerate our growth journey. We will also continue to rely on our business system to guide acquisition integrations, to help optimize sourcing and logistics, and to further strengthen our culture of continuous improvement throughout the organization.

Our external guidance range for 2021 includes a double-digit increase in adjusted earnings per share at the midpoint, excluding any benefit from potential capital deployment. We believe that the goals we have set reflect a high level of expectations for our team, and the commitment to delivering the high level of performance that investors have come to expect from SPX Corporation.

Meeting Attendance and Voting

All SPX stockholders of record at the close of business on March 15, 2021, are entitled to vote on the matters listed at the Annual Meeting. To ensure that your shares will be represented, we ask you to vote by telephone, mail, or over the internet as soon as possible.

##### Table of Contents

CORPORATE GOVERNANCE

CODE OF ETHICS AND BUSINESS CONDUCT

We have adopted a Code of Ethics and Business Conduct that applies to all our directors, officers, and employees, including our chief executive officer and senior financial and accounting officers. Our Code of Ethics and Business Conduct requires each director, officer, and employee to avoid conflicts of interest; comply with all laws and other legal requirements, conduct business in an honest and ethical manner, and otherwise act with integrity and in the best interest of our Company and our stockholders. In addition, our Code of Ethics and Business Conduct acknowledges special ethical obligations for financial reporting. We maintain a current copy of our Code of Ethics and Business Conduct, and we will promptly post any amendments to or waivers of our Code of Ethics and Business Conduct regarding our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, on our website (www.spx.com) under the heading “Investor Relations—Corporate Governance—Commitment to Ethics and Compliance.”

CORPORATE GOVERNANCE GUIDELINES

As part of its ongoing commitment to good corporate governance, the Board has codified its corporate governance practices into a set of Corporate Governance Guidelines. These guidelines are reviewed annually by the Nominating and Governance Committee and approved by the full Board to maintain the most up to date governance practices. These guidelines, assist the Board in the exercise of its responsibilities and may be amended by the Board from time to time. Our Corporate Governance Guidelines are available on our website (www.spx.com) under the heading “Investor Relations—Corporate Governance.”

DIRECTOR INDEPENDENCE

Our Corporate Governance Guidelines require that a substantial majority of the Board meet the independence requirements of the listing standards of the New York Stock Exchange (“NYSE”). At least annually, our Board reviews whether each of our directors is independent. The Board has adopted Independence Standards to help guide it in this process. Our Independence Standards are available on our website (www.spx.com) under the heading “Investor Relations—Corporate Governance.” Based on its most recent annual review, the Board has concluded that Patrick J. O’Leary, Ricky D. Puckett, David A. Roberts, Meenal A. Sethna, Ruth G. Shaw, Robert B. Toth, Tana L. Utley, and Angel S. Willis (a nominee to be added to the Board if she is elected at the Annual Meeting), are independent, as defined in our Independence Standards and the listing standards of the NYSE. The Board has concluded that Eugene J. Lowe, SPX’s President and Chief Executive Officer (“CEO”), is not independent as defined in our Independence Standards and the listing standards of the NYSE.

The non-employee members of the Board meet regularly in executive session without management. In addition, the non-employee members of the Board meet in executive session on a regular basis with the CEO and such other management as the Board deems appropriate.

ESG MATTERS

In addition to our Corporate Governance Guidelines, we have implemented programs to ensure that SPX is engaged in effective and appropriate environmental, social and governance (“ESG”) practices. The Nominating and Governance Committee oversees the governance of SPX’s ESG program. At the direction of the Board, the Company has formed an ESG Steering Committee, which provides periodic reports to the Nominating and Governance Committee on the Company’s ESG initiatives and efforts. These initiatives and efforts are published in SPX’s sustainability report, the most recent of which can be found on our website (www.spx.com), under the heading “Investor Relations—Corporate Governance—Sustainability Performance.”

RISK OVERSIGHT

The Board exercises overall risk governance at SPX, with committees taking the lead in discrete areas of risk oversight. For example, the Audit Committee is primarily responsible for risk oversight relating to financial statements; the Compensation Committee is primarily responsible for risk oversight relating to executive compensation; and the Nominating and Governance Committee is primarily responsible for risk oversight relating to corporate governance, including with respect to ESG matters. Committees report to the Board on risk management matters.

Management presents to the Audit Committee its view of the principal risks facing SPX in a dedicated “enterprise risk management” presentation at least once a year. Matters such as risk tolerance and management of risk are also discussed at this meeting. Further, management periodically reviews with the Audit Committee our major risk exposures, identified through the enterprise risk management process, as well as the steps management has taken to monitor and control such exposures.

|  | 2021 PROXY STATEMENT |  | 1

##### Table of Contents

CORPORATE GOVERNANCE

We conduct an annual in-depth review of the risks associated with our incentive-based compensation arrangements and practices, and management presents to the Compensation Committee its view on such risks. In 2020, we again determined that the risks associated with these arrangements are appropriate. See “Risk Analysis,” on page 32, for further discussion.

In addition, the Board explicitly addresses risk in a wide range of discussions, including those relating to segment or business unit activities, the impact of the COVID-19 pandemic, specific corporate functions (such as treasury, tax, capital allocation, legal, etc.), legacy asbestos liabilities, cybersecurity, claims related to our South African operations, ongoing litigation, and consideration of extraordinary transactions. In addition to the Board’s active role in these discussions, the Board has full access to management, as well as the ability to engage advisors, in order to assist in its risk oversight role.

CHARITABLE CONTRIBUTIONS

It is the policy of the Board that no officer or director shall solicit contributions for charities from other officers or directors or directly from SPX if the director or officer soliciting the contributions personally controls the charity. In addition, no officer or director shall solicit contributions from other officers or directors for charities controlled by SPX.

From time to time, SPX may make contributions to charitable organizations for which a member of our Board or one of our executive officers serves as a director or officer. In the past three fiscal years, however, the amount of any of these contributions in any single fiscal year has not exceeded the greater of (1) $1 million or (2) 2% of the charitable organization’s consolidated gross revenues.

STRATEGIC PLANNING

Our Board meets regularly to discuss the strategic direction and the issues and opportunities facing our Company. Our Board has been instrumental in determining our next steps as we focus on growth with an emphasis on strengthening our current complement of businesses.

• |  | Constant Focus on Strategy: Throughout the year, our Board provides guidance to management on strategy and helps to refine business plans to implement the strategy.

• |  | Detailed Annual Review of Strategy: Each year, typically during the third quarter, the Board holds an extensive meeting with senior management dedicated to discussing and reviewing our long-term business plans and overall corporate strategy. As part of this meeting, our CEO leads a discussion of potential growth opportunities, key risks to the plans and strategy, and mitigation plans and activities.

Furthermore, in setting our business strategy, the Board plays a critical role in determining the types and appropriate levels of risk undertaken by the Company.

COMMUNICATIONS WITH DIRECTORS

Interested parties may communicate with any of our non-employee directors by writing to the director in care of our Corporate Secretary at our address shown on the Notice of Annual Meeting of Stockholders accompanying this Proxy Statement. In accordance with the policy adopted by our non-employee directors, our Corporate Secretary will promptly relay to the addressee all communications that he determines require prompt attention by a non-employee director and will regularly provide the non-employee directors with a summary of all substantive communications.

DIRECTOR NOMINEES, QUALIFICATIONS, AND DIVERSITY

The Nominating and Governance Committee is responsible for proposing director nominees and will consider director nominee recommendations offered by stockholders in accordance with our By-laws. The Nominating and Governance Committee selects individuals as director nominees based on the following:

• |  | Business and professional accomplishments;

• |  | Integrity;

• |  | Demonstrated ability to make independent analytical inquiries;

• |  | Ability to understand our businesses;

2 |  | 2021 PROXY STATEMENT |  |

##### Table of Contents

CORPORATE GOVERNANCE

• |  | Absence of conflicts of interest;

• |  | Willingness to devote the necessary time to Board duties; and

• |  | Alignment of skills with those identified by the Board as desirable for the advancement of the Company; for more details on such identified areas, see our skills matrix under “Director and Nominee Skills and Experience” on page 15.

The Board and the Nominating and Governance Committee require each director to have a proven record of success and leadership. In order to maintain appropriate flexibility to adjust to evolving needs, neither the Board nor the Nominating and Governance Committee has set minimum requirements with respect to age, education, or years of business experience or has designated specific expertise required for directors. Rather, the Nominating and Governance Committee seeks to structure the Board so that it consists of a diverse group of individuals, each with a unique combination of skills, experience, and background. The Nominating and Governance Committee has no set diversity policy or targets, but places what it believes to be appropriate emphasis on certain skills, experience, and background that it determines adds, or would add, value to our Board. In addition, the Nominating and Governance Committee considers the demographic make-up of the board and emphasizes identifying and recruiting candidates that are members of under-represented communities. Knowledge of our industries and strategic perspective, as well as financial expertise and experience with business development, mergers and acquisitions, are examples of attributes that our Board and the Nominating and Governance Committee consider important. The Nominating and Governance Committee also considers effective interaction among Board members and between the Board and management to be crucial factors in considering individuals for nomination.

The Nominating and Governance Committee considers the criteria listed above at least each time the director is re-nominated for Board membership or when considering additions to the Board. At such times as the Board and the Nominating and Governance Committee determine there is a need to add or replace a director, the Nominating and Governance Committee identifies director candidates through references from its members, other directors, management, or outside search firms, if appropriate. The Nominating and Governance Committee applies the same process and standards to the evaluation of each potential director nominee, regardless of whether he or she is recommended by one or more stockholders or is identified by some other method.

Any stockholder who wishes to recommend an individual for consideration by the Nominating and Governance Committee should provide written notice of the recommendation to our Corporate Secretary at our address on the cover of this Proxy Statement. Such notice must be accompanied by certain disclosures, including written information about the recommended nominee’s business experience and background, and documentation required under our By-laws for stockholder nominations of directors, as well as a consent in writing signed by the recommended nominee that he or she is willing to be considered as a nominee and, if nominated and elected, that he or she will serve as a director. In addition, any director nominee must provide information we may reasonably request in order for us to determine the eligibility of such nominee to serve as an independent director.

Once the Nominating and Governance Committee identifies a director candidate, directors and members of management interview the candidate. Following that process, the Nominating and Governance Committee and the Board determine whether to nominate the candidate for election at an annual meeting of stockholders or, if applicable, to appoint the candidate as a director. Any such nomination or appointment is subject to acceptance by the candidate. Our By-laws require that any director appointed to the Board other than at an annual meeting of stockholders be submitted for election by our stockholders at the next annual meeting.

DIRECTOR ELECTION

In uncontested elections, we elect directors by majority vote. Under this voting standard, the number of shares voted “for” a director must exceed the number of shares voted “against” that director. In a contested election, directors are elected by a plurality of the votes represented in person or by proxy at the meeting. An election is contested if the number of nominees exceeds the number of directors to be elected. Whether or not an election is contested is determined ten days in advance of the date we file our definitive proxy statement with the Securities and Exchange Commission (“SEC”). This year’s election is uncontested. Accordingly, the majority vote standard will apply.

If a nominee already serving as a director is not elected at an annual meeting, then the law of the State of Delaware (SPX’s state of organization) provides that the director will continue to serve on the Board as a “holdover director” until his or her successor is elected. Our Nominating and Governance Committee, however, has established procedures in our Corporate

|  | 2021 PROXY STATEMENT |  | 3

##### Table of Contents

CORPORATE GOVERNANCE

Governance Guidelines requiring directors to tender to the Board advance resignations. The Board will nominate for election or re-election as a director only those candidates who agree to tender, promptly following each annual meeting of stockholders at which they are subject to re-election as a director, irrevocable resignations that will be effective only if (1) the director fails to receive a sufficient number of votes for re-election at the next annual meeting of stockholders at which he or she faces re-election, and (2) the Board accepts the resignation. In addition, the Board will fill director vacancies and new directorships only with candidates who agree to tender, promptly following their appointment to the Board, the same form of resignation tendered by other directors in accordance with this provision.

In the event a resignation is triggered as a result of a director failing to receive sufficient votes, the Nominating and Governance Committee will consider the resignation and make a recommendation to the Board on whether to accept or reject it, or whether other action should be taken. The Board will consider the Nominating and Governance Committee’s recommendation and publicly disclose its decision and the rationale behind it in a Current Report on Form 8-K filed with the SEC within 90 days from the date of certification of the election results.

ATTENDANCE AT ANNUAL MEETING

It is our policy to invite all members of our Board to attend our Annual Meeting. While their attendance is not required, all but one of our directors serving at the time of our last Annual Meeting attended that meeting.

INDEPENDENT COMPENSATION CONSULTANT

The Compensation Committee has retained Pearl Meyer as its sole independent compensation consultant. Pearl Meyer does not provide any services to our Company other than advice to and services for the Compensation Committee relating to compensation of all executives and the Nominating and Governance Committee relating to compensation of our non-employee directors. The independent compensation consultant may provide other consulting services to SPX, on a limited basis and only with approval from the Compensation Committee or the Nominating and Governance Committee. The Compensation Committee reviews services provided by its independent compensation consultant on at least an annual basis.

The independent compensation consultant:

• |  | Assesses data relating to executive pay levels and structure;

• |  | Reviews design and recommendations for annual and long-term incentive plans;

• |  | Conducts risk assessment of the Company’s executive incentive plans;

• |  | Works with management to develop management’s recommendations to the appropriate committee on compensation amounts and structure for all directors and executive officers other than the President and CEO;

• |  | Presents to the Compensation Committee recommendations on compensation amounts and structure for the President and CEO;

• |  | Presents to the Nominating and Governance Committee recommendations on compensation amounts and structure for the non-employee directors;

• |  | Reviews and provides analysis to the Compensation Committee on management’s recommendations relating to executive officer compensation;

• |  | Recommends the list of peer companies against which we benchmark our executive officer and director compensation for approval by the Compensation Committee;

• |  | Reviews and supports preparation of compensation-related proxy statement disclosures;

• |  | Consults on the process for determining the median-compensated employee for the CEO pay ratio; and

• |  | Advises the relevant committee on regulatory, market practices, and other trends and developments in the area of executive and director compensation.

The Compensation Committee has directed the independent compensation consultant to collaborate with management, including our human resources function, to obtain data, clarify information, and review preliminary recommendations prior to

the time they are shared with the relevant committee. The Compensation Committee has considered the independence of Pearl Meyer in light of SEC rules, NYSE listing standards, and the requirements of the Compensation Committee’s charter. The Compensation Committee requested and received a letter from Pearl Meyer addressing relationships with and the independence of Pearl Meyer and the Pearl Meyer senior advisor involved in the engagement. In addition to this information, the Compensation Committee noted the following protocols designed to help ensure objectivity:

• |  | The consultant reports directly to the Compensation Committee or, in the case of matters relating to non-employee director compensation, to the Nominating and Governance Committee;

• |  | Only the Compensation Committee and the Nominating and Governance Committee have the authority to retain or terminate the consultant with respect to services provided to the relevant committee; and

• |  | The consultant meets as needed with committee members, without the presence of management.

The Compensation Committee concluded that the work performed by Pearl Meyer and Pearl Meyer’s senior advisor involved in the engagement did not raise any conflict of interest and that each was independent.

CONSIDERATION OF RELATED-PARTY TRANSACTIONS

Pursuant to its charter and a written related-party policy, the Audit Committee is charged with reviewing and approving any related-party transactions. A related-party transaction is a transaction involving SPX and any of the following persons: a director, director nominee, or executive officer of SPX; a holder of more than 5% of SPX common stock; or an immediate family member or person sharing the household of any of these persons. When considering a transaction, the Audit Committee is required to review all relevant factors, including whether the transaction is in the best interest of our Company; our Company’s rationale for entering into the transaction; alternatives to the transaction; whether the transaction is on terms at least as fair to our Company as would be the case were the transaction entered into with an unrelated third party; potential for an actual or apparent conflict of interest; and the extent of the related party’s interest in the transaction.

BOARD LEADERSHIP STRUCTURE

Our governance documents provide the Board with flexibility to select the leadership structure that is most appropriate for the Company and its stockholders in consideration of then-current circumstances. The Board regularly evaluates the Company’s leadership structure and has concluded that the Company and its stockholders are best served by not having a formal policy regarding whether the same individual should serve as both Chairman of the Board and CEO. This approach allows the Board to elect the most qualified director as Chairman of the Board while also maintaining the ability to combine or separate the Chairman of the Board and CEO roles when necessary or appropriate. We currently separate the positions of Chairman of the Board and CEO.

Currently, Eugene J. Lowe, III, serves as our President and CEO, a position he has held since September 26, 2015. In this role, Mr. Lowe is responsible for managing the day-to-day operations of the Company and for planning, formulating, and coordinating the development and execution of our corporate strategy, policies, goals, and objectives. Mr. Lowe is accountable for Company performance and reports directly to the Board.

Patrick J. O’Leary has served as our non-employee Chairman of the Board since September 26, 2015. In this role, Mr. O’Leary’s responsibilities include the following:

• |  | Serving as a resource to the President and CEO in connection with strategic planning and other matters of strategic importance to the Company;

• |  | Receiving reports from the President and CEO, organizing and facilitating the President and CEO evaluation process, and providing ongoing, constructive feedback to the President and CEO;

• |  | Consulting with the President and CEO regarding the Company’s relations and communications with stockholders of the Company, analysts, and the investor community;

• |  | Chairing meetings of the Board;

• |  | Setting the schedule and agenda for Board meetings in consultation with the President and CEO;

|  | 2021 PROXY STATEMENT |  | 5

CORPORATE GOVERNANCE

• |  | Determining the information that is sent to the Board in consultation with the President and CEO;

• |  | Presiding over the executive sessions and other meetings of the non-employee directors; and

• |  | Communicating the results of meetings of the non-employee directors to the President and CEO and other members of management, as appropriate.

Our Corporate Governance Guidelines provide that in the event the Board determines that the same individual should again serve as both Chairman of the Board and CEO, the Board will appoint an independent director to serve as Lead Director. In that circumstance, the Lead Director would serve as the principal liaison between the independent directors and the Chairman and CEO; chair meetings of non-employee directors; develop the Board’s agenda in collaboration with the Chairman and CEO; and review and advise on the quality of the information provided to the Board.

The small size of our Board and the relationship between management and non-employee directors put each director in a position to influence agendas, the flow of information, and other matters. Our non-employee directors meet regularly in private session, without management, as part of our Board meetings and can also call additional meetings of the non-employee directors at their discretion.

The Board believes that its current leadership structure provides an appropriate balance among strategy development, operational execution, and independent oversight, and that this structure is currently in the best interests of the Company and its stockholders.

BOARD COMMITTEES

The Board met four times in 2020. The Board currently has a standing Audit Committee, Compensation Committee, and Nominating and Governance Committee. All but one director attended at least 75% of the meetings of the Board and of the committees on which he or she served in 2020, during his or her period of service. Dr. Ruth Shaw attended 71% of the Board and committee meetings on which she served in 2020. All of her absences were due to caring for her husband, who passed away on May 17, 2020. In light of the reason for her absences, the Board (with Dr. Shaw recusing herself) unanimously approved her absences in determining to nominate her for re-election as a director at the Annual Meeting. Each committee has adopted a charter that specifies the composition and responsibilities of the committee. Each committee charter is posted on our website (www.spx.com) under the heading “Investor Relations—Corporate Governance—Board Committees.”

The table below provides the member and 2020 meeting information for each of the Board committees.

DIRECTOR COMPENSATION

Annual Compensation

Our non-employee directors receive the following compensation:

Annual Retainer of Cash |  | $ | 75,000 |
Annual Equity Grant of Restricted Stock Units |  | $ | 130,000 |
Additional Fees: |  |  |  |
Chairman of the Board |  | $ | 125,000 |
Audit Committee Chair |  | $ | 20,000 |
Compensation Committee Chair |  | $ | 15,000 |
Nominating and Governance Committee Chair |  | $ | 10,000 |

We pay the annual cash retainer and any applicable additional cash fees to our non-employee directors in equal quarterly installments, paid in arrears. The portion of cash compensation for a director who has a partial quarter of service (due to joining or leaving the Board, or beginning or ending service as Chairman or a Committee Chair, during the quarter) is pro-rated. We do not pay meeting fees or additional compensation to directors for special meetings.

The annual equity grant of restricted stock units (“RSU”) is made under the SPX Corporation 2019 Stock Compensation Plan (the “2019 Stock Plan”). The number of RSUs awarded is calculated by dividing the $130,000 annual equity retainer by the closing price of the Company’s stock on the date of grant and rounding up to a full share. The RSU award is granted in connection with our Annual Meeting and vests the day before the following annual meeting. Vesting is subject to the director’s continued service on our Board through such vesting date. The annual equity grant for a director who has a partial year of service (due to joining the Board during the year) is pro-rated.

Our non-employee directors have the option to defer settlement and payout of vested RSU grants until six months after separating from service on our Board (or, if earlier, a Change in Control as defined in the 2019 Stock Plan). A non-employee director must generally make such deferral election in the year prior to the grant of the RSU award.

We do not currently pay dividends or dividend equivalents with respect to the RSUs.

Directors who are SPX employees receive no compensation for their service as directors. Mr. Lowe, our President and CEO, received no compensation for his service as a director in 2020.

OTHER BENEFITS

Matching Gifts Program

We will make matching donations for qualified charitable contributions for any non-employee director up to a total of $10,000 per year.

Travel Reimbursements

We reimburse non-employee directors for the reasonable expenses of attending Board and committee meetings and for expenses associated with director training and development. From time to time, a director’s spouse may accompany the director to certain business functions, including on our corporate aircraft; in such instances, the value of the spouse’s travel is imputed for income tax purposes as income to the director (determined under the U.S. Department of Transportation’s standard industry fare level (“SIFL”)) and the incremental cost to SPX, if any, is included as other compensation in our Director Compensation Table if it, together with any other personal benefits, exceeds the threshold specified under SEC rules.

COMPENSATION EVALUATION PRACTICES

The Nominating and Governance Committee periodically reviews non-employee director compensation and makes recommendations to the Board. The Nominating and Governance Committee evaluates our non-employee director compensation against our peer companies and consults with our independent compensation consultant when reviewing compensation amounts and structure.

Director and Nominee Skills and Experience

Under the leadership of our Nominating and Governance Committee, our Board developed and maintains a director skills matrix that identifies expertise and experience that the Board believes contribute to an effective and well-functioning board and that the Board as a whole should possess.

The Nominating and Governance Committee and the Board use this matrix to identify areas for director training and as a tool to maintain a balanced and well-rounded board. In addition, the Nominating and Governance Committee considers these and other criteria as a guide, but not as a minimum set of requirements, when evaluating potential candidates for the Board. Together, this variety of skill sets, experiences, and personal backgrounds allows our directors to provide the diversity of thought that is critical to the Board’s decision-making and oversight process. The following chart indicates the director has gained experience in the attribute through a current or prior position other than his or her service on the SPX Corporation Board of Directors. For a better understanding of our Board qualifications and diversity, we encourage you to read “Director Nominees, Qualifications, and Diversity” beginning on page 2.

OWNERSHIP OF COMMON STOCK

Stock Ownership Guidelines

We maintain Stock Ownership Guidelines to emphasize the importance of substantive, long-term share ownership by our directors and officers to align their financial interests with those of our stockholders.

The guidelines are:

Position |  | Target Value
Non-Employee Directors |  | 3x annual retainer
Chief Executive Officer |  | 5x annual salary
Chief Operating Officer* |  | 4x annual salary
Other Executive Officers |  | 3x annual salary
Other Designated Executives |  | 1x annual salary

* SPX does not currently have the COO position.

Shares held in family trusts and shares held in retirement plan accounts are deemed to be owned shares for purposes of these guidelines. Unvested time-based stock (and stock unit awards) are deemed to be owned shares for purposes of these guidelines. Unexercised stock options and unvested performance-based stock (and stock unit awards) are excluded for purposes of these guidelines. We ask non-employee directors and executive leaders to attain the desired level of stock ownership within five years of initial election as a director or appointment to the officer position.

Once a non-employee director or executive leader attains the desired level of share ownership, he or she will continue to be in compliance with these guidelines even if he or she later falls below the guideline, as long as he or she retains at least 50% of the net shares acquired upon exercise of stock options and at least 50% of the net shares acquired pursuant to vested restricted equity awards and vested restricted stock unit grants until he or she again meets or exceeds the guidelines. “Net shares” means the shares remaining after disposition of shares necessary to pay the related tax liability and, if applicable, the stock option exercise price.

Each non-employee director and named executive officer was in compliance with these requirements as of March 15, 2021.

Compensation Discussion and Analysis

INTRODUCTION

This Compensation Discussion and Analysis (“CD&A”) provides information about our executive compensation program and the factors considered in making compensation decisions for the current and former executive officers listed in our Summary Compensation Table set forth below (the “named executive officers” or “NEOs”).

Our NEOs for 2020 are listed in the table below:

Named Executive Officer |  | Title
Eugene J. Lowe, III |  | President and Chief Executive Officer
James E. Harris |  | Vice President, Chief Financial Officer and Treasurer
J. Randall Data |  | President, South Africa and Global Operations
John W. Swann, III |  | President, Heating and Location & Inspection
Brian G. Mason |  | President, Transformer Solutions
Scott W. Sproule |  | Former Vice President, Chief Financial Officer and Treasurer

Mr. Sproule retired as Chief Financial Officer and Treasurer in August 2020 and retired as Vice President at the end of 2020.

EXECUTIVE SUMMARY

The impact of the COVID-19 pandemic was far reaching and had a range of impacts on our various markets and operational capabilities. We responded swiftly and effectively to the challenges created by the pandemic. The efforts of our teams across the globe drove solid performance in a year with revenue pressures, daily operational challenges, and high levels of uncertainty. Through the creation of our executive-led COVID-19 Task Force, the implementation of global monitoring and delivery frameworks across each business and function, and daily communication on key issues, we took timely and measured actions to address risks while keeping our teams safe. This active engagement not only resulted in strong financial performance for our stakeholders, but ensured that we maintained focus on our longer-term strategic growth initiatives, positioning us well for future years. The commitment, outstanding effort, and focus demonstrated by our leaders and teams cannot be emphasized enough. Without it, the potential negative impact of the pandemic on the organization could have been far greater. Ensuring that we recognize the current year’s strong performance, despite being faced with the COVID-19 pandemic, is important to key talent retention and the motivation of the overall workforce.

Our executive compensation program is designed to align short- and long-term rewards directly to business performance. The Compensation Committee continued to monitor the market carefully to understand changes resulting from the pandemic, ensuring that we maintain our competitive position, retain key talent, and deliver on commitments. We and the Compensation Committee of the Board (the “Committee”) benchmark our compensation strategy against our peer group companies, which rewards performance that results in value generation for our stockholders.

Summary of Key Business Accomplishments

As noted above, our agility and engagement in 2020 limited the potential adverse impact of the global COVID-19 pandemic, delivering strong financial results and progressing our strategic growth initiatives. Select accomplishments during 2020 include:

• |  | Delivered top quartile performance of our peer group on revenue, and top third performance on net profit and EPS growth;

• |  | Delivered 7% increase in stock price for the year and 74% over the latest three-year period—94th percentile amongst our compensation Peer Group for the latest three-year period;

The following graph shows our three-year total stockholder return (“TSR”) as compared to our peer group, as defined on page 26, the S&P 500 Index and the S&P 600 Small Cap Capital Goods Index for the period December 31, 2017 to December 31, 2020.

Three-Year TSR from December 31, 2017 to December 31, 2020

2020 Compensation Highlights

Our executive compensation program has three primary elements: base salary, annual incentive, and long-term incentives. Each of these compensation elements serves a specific purpose in our compensation strategy. Base salary is an essential component to any market-competitive compensation program. Annual incentives reward the achievement of short-term goals, while long-term incentives drive our NEOs to focus on stockholder value creation. Based on our performance, and consistent with the design of our program, the Committee made the following executive compensation decisions for 2020:

• |  | Base Salary. Annual salary increases ranged from 3.0% to 4.5%. These adjustments maintain alignment of our NEOs’ base salaries with the market to facilitate retention and reward for execution of responsibilities and delivery of performance. These adjustments also reflect the contributions made by our NEOs in connection with executing on key initiatives and the Company’s strategic priorities over the course of the year. For details, please see page 26.

EXECUTIVE COMPENSATION

• |  | Annual Incentive. Based on overall performance and the very unique circumstances presented by the global pandemic, the Compensation Committee elected to exercise discretion, on a limited basis, to award those aligned to the corporate metrics or to a business that was determined to have performed strongly through the pandemic, 67% of their target award. The payout at the corporate level would have otherwise been 40%. For details on each NEO’s award, please see page 28.

• |  | Long-Term Incentives. All of our NEOs received equity and equity-based awards in 2020. Target award amounts and the mix of awards granted are described on page 28 of this CD&A. Performance for the measurement period of January 1, 2018 through December 31, 2020 exceeded maximum metric for relative TSR resulting in the maximum allowable payout capped at 150% for performance shares. For the cash-based awards that were granted to NEO’s in 2018, segment income for the same period achieved 93.6% performance against target. No discretion was applied for this award. For details, please see page 29.

EXECUTIVE COMPENSATION PROGRAM

Reflecting the Voice of Our Stockholders

We carefully consider the results of our stockholder Say-on-Pay vote from the previous year. At our

2020 Annual Meeting, approximately 96% of votes cast approved our executive compensation. Our

results have exceeded 90% approval each year since 2016, which we interpret as a strong endorsement of

our compensation program’s design and direction. We continue to actively seek and highly value the

perspectives of our investors. During the year, we reached out to stockholders owning approximately 75% of our

common stock. We have taken and will continue to take stockholder feedback into consideration as we evolve our

compensation program. Most importantly, we are committed to ensuring that our ongoing program is designed in the

best interests of both our stockholders and executives.

Summary of Compensation Program

| • |  | Sets base salaries that are in line with the market, facilitating attraction, retention, and reward for execution of responsibilities and delivery of performance; |

| • |  | Emphasizes variable compensation programs, greater than 80% of CEO and greater than 65% of other NEOs pay at risk; |

| • |  | Provides that a majority of long-term incentives to NEOs are performance based; |

| • |  | Correlates between annual incentive payouts and stockholder returns, with 2020 targets that exceeded prior year results on operating income, cash flow, and revenue; |

| • |  | Grants equity awards with double-trigger termination payments upon a change in control; |

| • |  | Includes a relative TSR component of long-term incentives to align with stockholder value; |

| • |  | Freezes historic defined benefit pension plans, with no NEO participants; |

| • |  | Eliminates historic perquisites, such as retiree medical benefits; and |

| • |  | Prohibits NEO hedging or pledging of our common stock. |

EXECUTIVE COMPENSATION

Our Compensation Principles

Our executive compensation program is centered around the following principles:

Alignment with Stockholders’ Interests |  | Executive officers’ interests should be directly aligned with those of stockholders through a compensation program that emphasizes an appropriate balance of both short- and long-term financial performance and is directly affected by our stock price. Requiring executive officers to hold a meaningful amount of equity supports alignment to stockholder interests.
Link to Business Priorities and Performance |  | A significant portion of total compensation should be variable and subject to the attainment of certain specific and measurable performance goals and objectives.
Competitiveness |  | Target total compensation should be competitive with that being offered to individuals holding comparable positions at other public companies with which we compete for leadership and market talent.
Governance |  | Maintaining best-practice executive compensation governance standards is critical to the decision-making process and the ability to manage risk. Doing so is in the best interests of our stockholders and executives.

Components of Total Direct Compensation

For 2020, we continued to focus on ensuring alignment of pay practices with stockholder interests and driving a pay-for-performance culture.

Design and characteristics of the SPX compensation program include:

• |  | Base Salary. Annual salary for our NEOs is targeted at the market median of peer companies and is in line with responsibilities, performance, contributions, and overall experience.

• |  | Annual Incentive. Performance metrics focus on delivering key annual objectives with financial targets directly tied to the achievement of goals related to operating income, cash flow, and revenue.

• |  | Long-Term Incentives. Long-term incentive (“LTI”) awards align compensation and long-term performance. Mix of awards include:

| • |  | Stock Options (“Options”) that vest ratably over a three-year period;

| • |  | Performance Stock Units (“PSUs”) tied to relative TSR (“r-TSR”) compared to a peer group within the S&P 600 Small Cap Capital Goods Index over a three-year performance measurement period, with potential payout range of 0% to 150% of target, and cannot exceed target if our TSR is negative;

| • |  | Restricted Stock Units (“RSUs”) that vest ratably over a three-year period.

Beginning with the compensation awards made in 2019, the Committee decided to no longer grant cash performance unit (CPU) awards and to proportionately increase PSU awards. As a result, all of the 2020 LTI compensation grants are comprised of equity-based awards. The Committee evaluates the Company’s compensation programs annually and considers a number of factors when evaluating the components of LTI compensation, including equity use and dilution, compensation trends to attract and retain talent, and alignment of incentives with Company performance.

Mix of Compensation Elements

The following charts show that for 2020 the mix of compensation elements targeted for our NEOs was heavily weighted toward variable compensation. The mix of LTI is based on the allocation value used in determining the number of units or options, as applicable, for each award.

Our CEO’s Pay-for-Performance Alignment

The following chart shows our CEO’s compensation relative to our TSR compared with our peer group of companies listed on page 26, demonstrating how our executive compensation program aligns with performance. This chart is based on our three-year TSR; the average of our CEO’s total compensation for 2018, 2019, and 2020 by percentile; and the average total compensation for CEOs at our peer companies, from their most recent three annual proxy statement filings.

| * | Peer company compensation based on 2017, 2018, and 2019 compensation data from each company’s three most recent annual proxy statement filings.

Our CEO’s relative pay rank falls within the median of our peer companies consistent with, our philosophy to align executive compensation with that of our peers and provide variable incentive compensation that rewards executives at higher levels when superior performance is achieved.

The Role of the Compensation Committee

The Committee is responsible for overseeing the design and administration of the executive compensation program so that the program is consistent with our compensation philosophy. The Committee reviews compensation levels for all of our executive officers, including our NEOs. The Committee also makes all final compensation decisions regarding our NEOs and officers, except for the CEO, whose compensation is reviewed and approved by the full Board, excluding Mr. Lowe, based upon recommendations of the Committee.

The Committee also works very closely with its independent compensation consultant and with management to examine the effectiveness of the Company’s executive compensation program. Details of the Committee’s authority and responsibilities are specified in the Committee’s charter, which is available on our website (www.spx.com) under the heading “Investor Relations—Corporate Governance—Board Committees.”

The Role of Management

Certain members of our senior management team help prepare for and attend meetings where executive compensation, Company and individual performance, and competitive compensation levels and practices are discussed and evaluated. However, only the Committee members are allowed to vote on decisions regarding executive compensation. The Committee also receives recommendations from the CEO regarding the compensation of our other officers, including the other NEOs. The CEO does not participate in the deliberations of the Committee and Board regarding his own compensation.

The Role of the Independent Compensation Consultant

The Committee engages an independent compensation consultant to provide expertise on competitive pay practices and compensation program design and an objective assessment of any inherent risks of any compensation programs. Pursuant to the authority granted to it under its charter, the Committee has retained Pearl Meyer as its independent consultant. The Committee has conducted an independence assessment of Pearl Meyer in accordance with SEC rules, NYSE listing standards, and the requirements of the Compensation Committee Charter, and has determined that work performed by Pearl Meyer does not create a conflict of interest and that Pearl Meyer is independent.

EXECUTIVE COMPENSATION

The Role of the Peer Group

Our executive compensation program takes into account the compensation practices of companies with which we compete or could compete for executive talent. Peer companies are selected based on a number of factors including size, industry, and markets served. There were no changes to companies included in the peer group in 2020 from the group used in 2019. For purposes of setting 2020 executive compensation, the Committee used the following peer companies (“peer group”):

SPX Peer Companies
Altra Industrial Motion Corp. (AIMC) |  | Graco Inc. (GGG)
Barnes Group Inc. (B) |  | Harsco Corporation (HSC)
Chart Industries, Inc. (GTLS) |  | IDEX Corp. (IEX)
CIRCOR International, Inc. (CIR) |  | NN, Inc. (NNBR)
Colfax Corp. (CFX) |  | Nordson Corporation (NDSN)
Crane Co. (CR) |  | Regal Beloit Corporation (RBC)
Curtiss-Wright Corporation (CW) |  | Rexnord Corporation (RXN)
Enerpac Tool Group Corp (EPAC) |  | SPX FLOW, Inc. (FLOW)
EnPro Industries, Inc. (NPO) |  | TriMas Corporation (TRS)

Our peer companies were drawn from a pool of potential companies identified by our management either as key competitors for senior talent or as having businesses or serving end markets similar to our Company. These companies were further reviewed for appropriateness as peers by Pearl Meyer prior to Committee approval. The primary factors used to generate the group were as follows:

• |  | Similar business mix to SPX;

• |  | Similar end markets to SPX;

• |  | Competitors for executive talent;

• |  | Market capitalization; and

• |  | Revenue of approximately 0.4 to 2.5 times SPX’s revenue.

SPX annual revenues for 2020 are approximately at the median peer company.

The Committee reviews the peer group regularly to assure alignment and adds or removes companies as peers as it deems appropriate and necessary to maintain competitive and balanced alignment. The Committee uses the peer group data to assist in compensation decisions around base salary, short-term incentives, and long-term incentives, as well as in benchmarking other executive compensation matters.

Base Salary

Base salary represents annual fixed compensation and is a standard element of compensation necessary to attract and retain talent. Base salary levels are reviewed annually. When making adjustments, the Committee considers the Company’s overall performance; the NEO’s individual performance, experience, career potential, and tenure with the Company; and competitive market practices. The Committee approved increases in annual base salary, effective March 30, 2020, (for Mr. Harris upon the commencement of his employment on August 17, 2020), as reflected in the table below, to continue to improve the competitive market position of our NEO’s base salaries relative to our peer group.

Named Executive Officer |  | Base Salary (From 3/18/2019) |  | Base Salary (From 3/20/2020) |  | % Adjustment
Eugene J. Lowe, III |  |  | $ | 884,764 |  |  |  | $ | 925,000 |  |  |  |  | 4.5 | %

EXECUTIVE COMPENSATION

Annual Incentive

Executive Bonus Program

Our Executive Bonus Program pays annual bonuses ranging from 0% to 200% of target by reference to three key metrics: adjusted operating income* adjusted free cash flow*, and adjusted revenue.*

The Committee selected these metrics to be transparent and to provide clarity and consistency in calculating bonuses. In setting short-term incentive goals, SPX management and the Committee utilized a number of data points to focus targets on driving the Company’s strategic priorities, including setting goals that incentivize delivery of annual objectives. Further, the use of adjusted* metrics is intended to drive management to focus on the performance of our go forward businesses, which excludes the South African projects.

2020 targets were set to drive continued growth in revenue and operating income as well as to deliver adjusted free cash flow* in excess of 100% conversion of adjusted net income from continuing operations.*

As previously discussed, even with the pandemic, we were able to deliver a strong financial performance in 2020. Our shorter cycle businesses were more dramatically impacted most immediately by COVID-19 market conditions, but generally began to recover late in 2020. Our longer cycle businesses continued to perform well against their 2020 targets while our more project-based businesses saw the most volatility as a number of project deliverables and timelines were delayed. As a result, we achieved year-over-year growth in adjusted revenue*, adjusted segment income*, and adjusted earnings per share* of 1.9%, 3.2%, and 1.4%, respectively. In addition, we reported adjusted free cash flow* of $123.3 million, or just over 96% of reported adjusted net income* during 2020.

The table below shows the 2020 threshold, target, and maximum goals for each of the relevant metrics under our Executive Bonus Program, as well as the adjusted performance results.

|  | Level of Performance ($ Millions) |  | Payout %
Performance Metric and Weighting |  | Threshold ($) |  | Target ($) |  | Maximum ($) |  | Actual ($)
Adjusted Operating Income* (50%) |  |  | $ | 182.0 |  |  |  | $ | 192.0 |  |  |  | $ | 210.0 |  |  |  | $ | 182.7 |  |  |  |  | 53.4 | %
Adjusted Free Cash Flow* (25%) |  |  | $ | 120.0 |  |  |  | $ | 140.0 |  |  |  | $ | 160.0 |  |  |  | $ | 122.0 |  |  |  |  | 55.0 | %
Adjusted Revenue* (25%) |  |  | $ | 1,585.0 |  |  |  | $ | 1,615.0 |  |  |  | $ | 1,645.0 |  |  |  | $ | 1,539.3 |  |  |  |  | 0.0 | %
Total Corporate Results |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  | 40.4 | %

For incentive compensation purposes, adjusted operating income* of $182.7 million resulted in a 53.4% payout, with a weighting of 50%. Adjusted free cash flow* of $122.0 million resulted in a 55% payout, with a weighting of 25%. Adjusted revenue* of $1,539.3 million resulted in a 0% payout, with a weighting of 25%. Accordingly, based on these performance metrics the cumulative payout for 2020 results would be 40.4% of target for those NEOs with 100% of their bonus tied to corporate metrics.

Based on overall performance and the very unique circumstances presented by the global pandemic, the Compensation Committee elected to exercise discretion to award a bonus to those aligned to the corporate metrics or to a business that was determined to have performed strongly through the pandemic, at an amount equal to 67% of their target award. These groups took active steps to manage costs, facilitate productivity, and aggressively manage operations through the challenges. In the Committee’s view, if not for the impact of the pandemic, these individuals would have otherwise received bonuses between threshold and target performance and, due to their active management, results were strong relative to the risks facing the Company. Corporate results were estimated to be at or near target payout without the impact of COVID-19. In awarding this discretionary bonus, no executive officer received a different measurement center performance than did all other management and professional incentive plan participants for the same measurement center. Mr. Lowe, Mr. Harris, Mr. Data, and Mr. Sproule’s bonus payouts are tied 100% to the corporate results. Mr. Swann and Mr. Mason have target incentives that include both business unit and corporate results: 75% of their incentive is based on their role as business unit President, and 25% is based on corporate metrics. In addition to this discretionary award to increase the performance level to 67% from 40.4%, Mr. Data and Mr. Swann both received additional discretionary bonus amounts as individual performance modifiers in recognition of specific accomplishments and exceptional performance in 2020. Following application of calculated awards, discretionary awards where applicable, and the personal performance modifiers where applicable, the total annual incentive

payout by named executive officer is noted in the table below. Mr. Mason’s above-target payout is driven by the 190.6% performance achievement of the Transformer business and does not include any discretionary award.* Other than for Mr. Mason, amounts totaling the total bonus set forth in the table below are reported in the Summary Compensation Table in the “Bonus” column, for the discretionary portion of the total annual incentive award, and in the “Non-Equity Incentive Plan Compensation” column, for the payout based on the 40.4 % achievement level.

Executive Bonus Results for 2020

The table below shows the total annual bonuses earned by our NEOs for 2020.

Named Executive Officer |  | Base Salary as of 12/31/2020 |  | Target Payout (as a % of Base Salary) |  | Bonus Achieved (% of Target Payout) |  | Total Bonus
Eugene J. Lowe, III |  |  | $ | 925,000 |  |  |  |  | 100 | % |  |  |  | 67.0 | % |  |  | $ | 619,750 |

(1) | The annual bonus payout for Mr. Harris is prorated based on his period of service. To offset the loss of cash incentive compensation under his prior employment arrangement, Mr. Harris received a sign-on bonus of $375,000 payable at the same time as the Company’s standard bonus payment timing. This sign-on bonus is to be repaid to the Company by Mr. Harris if he voluntarily terminates his employment with the Company or his employment is terminated by the Company for cause within 12 months of the payment date. This repayment obligation is ratably reduced during the year following the payment date for each month of his continued employment unless Mr. Harris fails to repay such amount upon the Company’s demand, in which case the full amount of the sign-on bonus is required to be repaid.

(2) | Mr. Sproule’s bonus payment is prorated based on his full time salary of $491,594 from January 1, 2020 through September 20, 2020, and part-time salary of $245,647 from September 21, 2020 through December 31, 2020.

Long-Term Incentives

Long-term incentives are an integral part of our executive compensation program. They are designed to align the financial interests of our NEOs with those of our stockholders through performance-based compensation that correlates with the creation of long-term stockholder value. Our long-term incentive awards also support our executive retention strategy.

For 2020, the Committee approved the following mix of LTI awards, which awards were granted in February 2020 under our stockholder approved plans:

• |  | Options that vest ratably over a three-year period;

• |  | PSUs tied to r-TSR compared to a peer group within the S&P 600 Small Cap Capital Goods Index over a three-year performance measurement period, with potential payout range of 0% to 150% of target, and cannot exceed target if our TSR is negative;

• |  | RSUs that vest ratably over a three-year period.

50% of the award value was allocated to PSUs with the remaining 50% divided equally between Options and RSUs.

The allocation of Options were based on the Black-Scholes valuation and RSUs and PSUs were based on the average closing fair market value of SPX stock for the 15 trading days immediately preceding the date of grant.

Stock Options

In 2020, awards of Options were granted to eligible participants, including each of the NEOs. The Committee approved the 2020 Option grants to the NEOs in February 2020, other than Mr. Harris whose Option award was approved in connection with the commencement of his employment on August 17, 2020. The 2020 Options grant agreement provides for time-based ratable vesting (of 331/3 percent per year) over a three-year period (generally subject to continued service during the period) with a maximum term of ten years. The Committee approves all grants of Options to be issued by the Company pursuant to approved equity grant guidelines.

Performance Stock Units

The 2020 awards of PSUs provide eligible participants, including each of the NEOs, the opportunity to receive shares of common stock based on pre-established financial performance targets over a specified three-year period (and generally subject to continued service during the performance period). The performance criteria for the PSUs are based on the r-TSR of SPX as compared to the results of a peer group within the S&P 600 Small Cap Capital Goods Index. At grant date, this peer group was comprised of 59 companies that compete in similar markets. Payouts under the program are made in shares of our common stock and range from 0% to 150% based on our TSR achievement versus the peer group. Payout cannot exceed target if our TSR is negative. Mr. Harris did not receive an award of PSUs for 2020.

Restricted Stock Units

As part of the 2020 long-term incentive program, participants, including each of the NEOs, received RSUs. The Committee approved the 2020 RSU grants to the NEOs in February 2020, other than Mr. Harris whose RSU award was approved in connection with the commencement of his employment on August 17, 2020. The 2020 RSU grant agreement provides for time-based ratable vesting (of 33 1/3 percent per year) over a three-year period (generally subject to continued service during the period). The Committee approves all grants of RSUs to be issued by the Company pursuant to approved equity grant guidelines.

Outstanding equity awards are more fully described in the “Outstanding Equity Awards at Fiscal Year-End” table in “Executive Compensation,” beginning on page 38.

Performance Based Incentive Results for 2018-2020

• |  | Performance Stock Units. The grant of PSUs made in February 2018 covered the measurement period of January 1, 2018 through December 31, 2020. The performance metric for these PSUs measures r-TSR compared to a peer group within the S&P 600 Small Cap Capital Goods Index. Total stockholder return delivered in the measurement period was 67%, which ranked in the 88th percentile, compared to threshold of 30th percentile, target of 50th percentile, and maximum of 75th percentile. The resulting performance achievement of the February 2018 grant exceeded the maximum allowable and, therefore, is capped at 150% payout of the PSUs. The final amount of the payout accounts for both the appreciation of the value of stock since the time of the grant and the 150% performance award.

• |  | Cash Performance Units. As part of the 2018 long-term incentive program, participants, including each of the NEOs then employed by the Company, received cash performance units with the opportunity to receive cash incentive payments based on SPX’s performance over the measurement period of January 1, 2018 through December 31, 2020 (and generally subject to continued service during the performance period). CPU payments were based on SPX’s actual performance over the measurement period. Payouts with respect to the CPUs could have ranged from 0% to 150% based on achievement of three-year cumulative adjusted segment income* targets, and each unit had a par value of $1.00. The performance metric for CPUs measures three-year cumulative adjusted segment income.* Adjusted segment income* achieved in the measurement period was $653.9 million, compared to threshold of $625.0M, target of $658.0 million, and maximum of $702.0 million. The resulting performance achievement of the February 2018 grant resulted in a 93.6% payout of the CPUs. As noted above, CPUs were discontinued in 2019, and there will be no further payout of CPUs after 2021.

OTHER PRACTICES, POLICIES, AND GUIDELINES

Policy on Hedging

No SPX director or employee may trade in derivative securities relating to SPX securities, such as put and call options or forward transactions.

Policy on Pledging

No SPX director or officer may pledge SPX securities.

Stock Ownership Guidelines

Our Stock Ownership Guidelines are designed to help ensure our officers’ interests are closely aligned with those of our long- term stockholders. Additional detail can be found in “Ownership of Common Stock—Stock Ownership Guidelines” on page 16.

Impact on Compensation from Misconduct–Clawbacks

If the Board were to determine that a NEO had engaged in fraudulent or intentional misconduct, it would take action to remedy the misconduct and impose appropriate discipline. Discipline would vary based on the facts and circumstances, but may include termination of employment and/or other appropriate actions.

We retroactively adjust compensation in the event of a restatement of financial or other performance results to the extent required by the Sarbanes-Oxley Act of 2002. Our executive bonus program provides for repayment or forfeiture of awards under specified circumstances if the Company, as a result of misconduct, is required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws. Any awards earned or accrued during the 12-month period following the first public issuance or filing with the SEC (whichever first occurred) of the financial document that failed to materially comply with a financial reporting requirement must be paid back to the Company. To the extent that the affected award was deferred under a nonqualified deferred compensation plan maintained by the Company rather than paid to the executive officer, the deferred amount (and any earnings from it) must be forfeited. Since 2013, our equity award agreements have provided that awards are subject to any compensation recovery policy adopted by the Company, as amended from time to time.

Other Benefits and Perquisites

We provide perquisites to attract and retain executives in a competitive marketplace, and we believe these benefits are generally consistent with market practices of our peer group and other comparable public industrial manufacturing companies. For a full listing of benefits and perquisites, see the “Summary Compensation Table” and accompanying footnotes beginning on page 34. We do not provide tax gross-up payments for perquisites.

Our CEO may utilize our aircraft for personal travel for himself and his family. Other executive officers may be permitted personal use of our aircraft for themselves and their families if approved by our CEO. We report the value of any personal use of our corporate aircraft by NEOs as ordinary taxable income based on Standard Industry Fare Levels and as compensation in the Summary Compensation Table on page 34 based on our incremental costs.

Retirement and Deferred Compensation Plans

None of our NEOs participate in an SPX defined benefit pension plan.

Our executives, along with the majority of our U.S.-based employee population, are eligible to receive matching contributions into the SPX Corporation Retirement Savings and Stock Ownership Plan (the “401(k) Plan”), a tax-qualified retirement savings plan. Matching contributions are immediately vested and are invested initially in the SPX Common Stock Fund in the form of units. This fund under the 401(k) Plan is primarily invested in SPX common stock, with a small portion of the fund in cash, for purposes of administrative convenience.

Executive officers and other senior-level management employees are also eligible to participate in the SPX Corporation Supplemental Retirement Savings Plan (the “SRSP”), a non-qualified deferred compensation plan that permits voluntary deferrals of base salary and annual bonuses.

For more information regarding these plans, see the Nonqualified Deferred Compensation table and accompanying narrative and footnotes, beginning on page 41.

Termination and Change-in-Control Provisions

As described below, all our NEOs, except our CEO, have entered into the current form of our change-in-control agreement as filed with the SEC.

On September 28, 2015, the Committee recommended, and the Board approved, an employment agreement and a change-in-control agreement for Mr. Lowe, President and Chief Executive Officer, and severance benefit agreements and change-in-control agreements for all other executive officers. The Committee reviews these agreements annually considering stakeholder interests and market competitiveness and will address adjustments as it deems appropriate.

Our severance arrangements are designed to protect stockholder interests by stabilizing management during periods of uncertainty. Executives often assign significant value to severance agreements because these agreements provide compensation for lost professional opportunities in the event of a negative qualifying event following a change-in-control.

Severance agreements can also be a powerful tool to discourage entrenchment of management, in that these agreements can offset the risk of financial and professional loss that management may face when recommending a sale to or merger with another company. Our severance arrangements are structured to serve the above functions, which differ, and are perceived by recipients to differ, from pay for performance. Accordingly, decisions relating to other elements of compensation have minimal effect on decisions relating to existing severance agreements. As described above, all our NEOs, except our CEO, have entered into the most current form of our severance benefit agreement as filed with the SEC.

We utilize a double-trigger in the event of a change-in-control. If the executive officer experiences a qualifying negative employment action following a change-in-control, then the executive officer becomes immediately vested in all previously- granted unvested SPX equity, including shares subject to performance vesting, at the target level of vesting. This feature is designed to be equitable in the event of dismissal without cause or resignation for good reason, and we believe it is appropriate in the event of termination following a change-in-control.

Severance and change-in-control terms are further discussed and quantified in “Potential Payments Upon Termination or Change-in-Control,” beginning on page 42.

Risk Analysis

Management regularly monitors and reviews our compensation program and the related risks and reports its findings to the Committee.

We do not believe our compensation policies and practices give rise to risks that are reasonably likely to have a material adverse effect on our Company. In reaching this conclusion, we considered the following factors:

• |  | Our compensation program is designed to provide a mix of both fixed and variable incentive compensation.

• |  | The variable portions of compensation (cash incentive and equity awards) are designed to reward both annual performance and longer-term performance. We believe this design mitigates any incentive for short-term risk-taking that could be detrimental to our Company’s long-term best interests.

• |  | For business unit level executives, a significant percentage of their compensation is based on the performance of our Company as a whole. This is designed to mitigate any incentive to pursue strategies that might maximize the performance of a single operating business unit to the detriment of our Company as a whole.

• |  | Our executive officers are subject to stock ownership guidelines that we believe incentivize our executives to consider the long-term interests of our Company and our stockholders and discourage excessive risk-taking that could negatively impact our stock price.

• |  | The Compensation Committee exercises risk oversight of our executive compensation program.

• |  | A qualitative risk assessment concluded that our plans do not have an unreasonable ratio between fixed and variable compensation. The annual bonus plans are capped at specified maximum percentages, which limits incentives to undertake excessive risk.

• |  | The executive and management annual bonus plans also have clawback provisions relating to any fraud, manipulation, or negligence in connection with computation of performance measures or payments under the plans.

• |  | Incentive plans are primarily determined by a formula tied directly to Company performance.

• |  | Sales incentive plans are regularly reviewed.

• |  | In addition to the structure of our plans, we mitigate any risk that may be generated by compensation plans through management oversight, compliance training and enforcement, and periodic reviews.

No single SPX business unit carries a significant portion of the Company’s risk profile, or has compensation structured in a significantly different manner than other business units within the Company, regardless of relative business unit profitability or compensation expense as a percentage of revenues.

Management does not believe that any of the design features pose a significant concern. Based upon this analysis, we determined that the compensation programs do not present a material risk.

(2) | To offset the loss of cash incentive compensation under his prior employment arrangement, Mr. Harris received a sign-on bonus of $375,000 payable at the same time as the Company’s standard annual incentive award payment timing. This sign-on bonus is to be repaid to the Company by Mr. Harris if he voluntarily terminates his employment with the Company or his employment is terminated by the Company for cause within 12 months of the payment date. This repayment obligation is ratably reduced during the year following the payment date for each month of his continued employment unless Mr. Harris fails to repay such amount upon the Company’s demand, in which case the full amount of the sign-on bonus is required to be repaid. For Messrs. Lowe, Harris, Data, Swann and Sproule, includes as bonus the discretionary increases in the annual incentive compensation payouts described on pages 27 and 28.

(3) | The amounts reported in the above table were calculated in accordance with FASB Accounting Standard Codification Topic 718 (“Topic 718”) to reflect their grant date fair-value given vesting requirements. See note 16 to the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2020, for additional information regarding the calculation of these numbers. Amounts presented for 2020 include restricted stock unit and performance stock unit awards. The values for performance stock units assumes achievement at the target performance level. At the maximum performance level of 150%, Mr. Lowe would receive $2,895,797, Mr. Data would receive $647,710, Mr. Swann would receive $571,568, Mr. Mason would receive $350,532, and Mr. Sproule would receive $594,434. Mr. Harris did not receive a performance stock unit award. See the “Grants of Plan-Based Awards” table for more information on these grants.

See “Compensation Discussion and Analysis,” beginning on page 19, for further discussion and explanation of each element of compensation.

CEO Pay Ratio

SEC rules require that we present a ratio of the total compensation of our CEO for 2020 to the total compensation received for 2020 by an identified median-compensated employee. These rules do not prescribe a particular method for identifying the median-compensated employee and permit companies to use reasonable methodologies for determining the median-compensated employee for the basis of presenting this ratio.

The 2020 annual total compensation for the identified median-compensated employee was $61,404 and the annual total compensation of our CEO was $6,117,525. Based on this information, for 2020 the ratio of the annual total compensation of our CEO to that of the identified median-compensated employee was 100 to 1.

To identify the median-compensated employee in 2020, we conducted a full analysis of our total employee population as of December 31, 2020, without the use of statistical sampling. We determined our median-compensated employee using “total compensation” paid during the full year 2020. “Total compensation” for this purpose consisted of gross wages which included base wages, overtime, shift differential, incentives, paid time off, and perquisites, as applicable. We did not annualize gross wages for employees who were not employed for the full year in 2020. For those employees located outside of the US, currencies were converted to US Dollars using the posted Bloomberg market rates as of December 29, 2020. We had an even number of employees when not including the CEO, therefore there are two employees for whom the number of employees with greater “total compensation” equals the number of employees with less “total compensation.” From those two employees, we selected as the median-compensated employee the one with higher “total compensation.” In determining the pay ratio for 2020, we calculated the total compensation of the median-compensated employee using the same methodology used in calculating the total compensation of our CEO, as reported in the Summary Compensation Table on page 34.

This pay ratio is a reasonable estimate calculated in a manner consistent with the applicable SEC rules using the data and methodology summarized above. As noted above, SEC rules for identifying the median-compensated employee allow companies to adopt a variety of methodologies to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the median employee compensation amount and CEO pay ratio reported by other companies may not be comparable to the amount and ratio reported above.

(1) | Value realized on exercise and value realized on vesting is based on the closing price of our common stock on the New York Stock Exchange on the date of exercise or vesting, as applicable. In connection with the vesting of stock awards, our NEOs surrendered shares to satisfy tax withholding requirements, which reduced the number of shares acquired and actual value they received upon vesting.

NONQUALIFIED DEFERRED COMPENSATION

The following table sets forth information relating to the SPX Corporation Supplemental Retirement Savings Plan (“SRSP”) for NEOs in 2020. Other members of senior-level management are also eligible to participate in the SRSP, a nonqualified deferred compensation plan that allows them to make pre-tax deferrals in excess of those permitted by the 401(k) Plan. Eligible executives may defer up to 50% of their base compensation (excluding annual bonuses) and up to 100% of their annual bonuses into the SRSP. Both base compensation and annual bonus deferral elections are made prior to the beginning of the year to which they relate.

A company match is made to the SRSP after the maximum company match has been made under the 401(k) Plan, and the deferrals and match are allocated to the fund(s) under the SRSP as selected by the participant.

In general, “eligible compensation” for purposes of the SRSP is the amount reported as wages on a participant’s Form W-2, (1) increased by (a) amounts contributed by the participant to the 401(k) Plan and the SPX Corporation Flexible Spending Account Plans, and (b) vacation and holiday pay paid after termination of employment; and (2) decreased by (a) reimbursements or other expense allowances, (b) fringe benefits (cash and non-cash), (c) moving expenses, (d) welfare benefits (provided that short-term disability payments are included and long-term disability payments are excluded), (e) employer-provided automobiles, mileage reimbursements, and car allowances for which no documentation is required, taxable and non-taxable tuition reimbursements, the taxable value of physical examinations, and group term life insurance coverage in excess of $50,000, (f) pay in lieu of notice, (g) deferred compensation, (h) the value of restricted shares and other equity awards, and (i) severance pay paid after termination of employment.

All matching contributions into the SRSP are made in cash and invested according to the participant’s elections. All participant and matching contributions vest immediately. There is no minimum holding period. The SRSP is unfunded and earnings are credited on account balances based on participant direction within the similar investment choices available in the 401(k) Plan. All returns in the SRSP and the 401(k) Plan are at market rates. In-service distributions are not allowed under the SRSP. All amounts deferred under the SRSP after 2009 will be paid in a lump-sum payment six months following termination of employment. Participants may elect to receive their pre-2009 accounts in a lump sum, annual installments (two to ten years), or monthly installments (up to 120 months) upon separation from service, on a date that is a specified number of months after retirement or separation from service, or on a specified date following separation from service (no later than attainment of age 701⁄2).

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE-IN-CONTROL

Our current NEOs are covered by change-in-control agreements, severance agreements, and stock plan award agreements governing compensation in the event of a termination of employment or a change in control of our Company. In addition, we have entered into an employment agreement with Mr. Lowe in lieu of a severance agreement. The following tables set forth the expected benefits to be received by each NEO (other than Mr. Sproule, who retired as an employee on December 31, 2020) in the event of their termination resulting from various scenarios, assuming a termination date of December 31, 2020 and a stock price of $54.54, our closing stock price on December 31, 2020 the last trading day of fiscal 2020.

PROPOSAL 2: APPROVAL OF NAMED EXECUTIVE OFFICERS’ COMPENSATION, ON A NON-BINDING ADVISORY BASIS (“SAY-ON-PAY”)

We are asking our stockholders to cast an advisory vote at our Annual Meeting to approve the compensation of our NEOs, as disclosed in this Proxy Statement.

Although the vote is non-binding, the Committee and the Board value your opinion and will consider the outcome of the vote in revising our compensation philosophy and making future compensation decisions.

We intend to seek approval of our executive compensation on an annual basis.

WHY YOU SHOULD APPROVE OUR NEO COMPENSATION

During 2020, we continued to focus on our commitment to having an executive compensation program that is aligned with stockholder interests and our goal of sustaining our meaningful pay-for-performance culture. At our 2020 Annual Meeting, approximately 96% of votes cast approved our executive compensation. The approval vote remains strong year-over-year, which we interpret as a strong endorsement of our executive compensation program design and direction — further validating that our program is structured in the best interests of both our stockholders and executives.

Our executive compensation and executive compensation program are more fully described in the “Compensation Discussion and Analysis,” beginning on page 19, and in the “Summary Compensation Table” and subsequent tables, beginning on page 34.

OVERVIEW

Key Components of Our Compensation Program

Base Salary

We target base salary for NEOs in line with the market median and our peer companies for established performers.

Annual Incentive

We focus annual bonus pay based on operating income, cash flow, and revenue goals.

Long-term Incentives

We target long-term pay based 50% on performance stock units, 25% on stock options, and 25% on restricted stock units.

Change in Control Provisions

We have double trigger provisions in the event of a change in control.

No Pledging or Hedging

We do not permit officer or director hedging or pledging of our common stock.

Benefits and Perquisites

We have no NEO participation in defined benefit pension plans or retiree medical benefits.

|  |  |  | YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE APPROVAL OF NAMED EXECUTIVE OFFICERS’ COMPENSATION, ON A NON-BINDING ADVISORY BASIS (“SAY-ON-PAY”).

AUDIT MATTERS

Audit Committee Report

The Audit Committee of the SPX Board of Directors consists of four directors. Each Audit Committee member is independent, as defined under SEC rules and the listing standards of the NYSE. The Audit Committee reviews SPX’s financial reporting process on behalf of the Board and is responsible for ensuring the integrity of the financial information reported by SPX.

Management is responsible for SPX’s financial reporting process, including its systems of internal and disclosure controls, and for the preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States (“US GAAP”). SPX’s independent registered public accounting firm, which is appointed by the Audit Committee, is responsible for auditing those financial statements. The Audit Committee’s responsibility is to monitor and review these processes. The Audit Committee has relied, without independent verification, on management’s representation that the financial statements have been prepared with integrity and objectivity and in conformity with US GAAP and on the representations of the independent registered public accounting firm included in the firm’s report on SPX’s financial statements.

In this context, the Audit Committee has met and held discussions with management and Deloitte & Touche LLP (“Deloitte”), SPX’s independent registered public accounting firm since 2002. Management represented to the Audit Committee that SPX’s consolidated financial statements were prepared in accordance with US GAAP, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent registered public accounting firm. The Audit Committee discussed with the independent registered public accounting firm matters required to be discussed by the Standards of the Public Company Accounting Oversight Board (“PCAOB”) for communication with audit committees, under which Deloitte must provide us with additional information regarding the scope and results of its audit of SPX’s consolidated financial statements.

In addition, we have discussed with Deloitte its independence from SPX and SPX management, including matters in the written disclosures required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence.

The Audit Committee discussed with SPX’s internal auditors and independent registered public accounting firm the overall scope and plans for its respective audits. The Audit Committee met with the independent registered public accounting firm, with and without management present, to discuss the results of its examinations, the evaluations of SPX’s internal controls, and the overall quality of SPX’s financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board, and the Board has approved, that the audited consolidated financial statements be included in SPX’s Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC.

The Audit Committee has reviewed and discussed with management its assertion and opinion regarding internal controls included in the 2020 Annual Report on Form 10-K as required by Section 404 of the Sarbanes-Oxley Act of 2002. Management has confirmed to the Audit Committee that at December 31, 2020 internal controls over financial reporting were appropriately designed and operating effectively to provide reasonable assurance regarding the reliability of financial reporting and the preparation of SPX’s consolidated financial statements for external purposes in accordance with US GAAP. The Audit Committee has also reviewed and discussed with Deloitte its audit and opinion regarding SPX’s internal control over financial reporting as required by Section 404, which opinion is included in the 2020 Annual Report on Form 10-K.

Other Audit Information

AUDIT AND NON-AUDIT FEE TABLE

During fiscal years 2019 and 2020, we retained our principal independent registered public accounting firm, Deloitte, to perform services in the following categories and amounts:

Audit Fees(1) |  | $ | 3,197,000 |  |  | $ | 3,570,000 |

All Other Fees |  |  | N/A |  |  |  | N/A |

(1) | Fees for audit services billed or expected to be billed relate to (a) audit of our annual financial statements and effectiveness of internal controls over financial reporting; (b) reviews of our quarterly financial statements; (c) statutory and regulatory audits; (d) audit of balance sheets and activities of acquired businesses; (e) other technical accounting assistance; and (f) consents, and other services related to SEC matters.

(2) | Fees for audit-related services include attest or audit services that are not required.

(3) | Fees for tax services relate to tax compliance and preparation, including the preparation of original and amended tax returns, claims for refunds, and tax payment planning.

PRE-APPROVAL BY AUDIT COMMITTEE

Our Audit Committee has adopted a policy that requires all audit and non-audit services performed by Deloitte to be pre-approved. The Audit Committee annually approves the fees and expenses for audit services performed by Deloitte, as well as for any regularly recurring non-audit services of the type covered by our annual engagement of Deloitte. In addition, our pre-approval policy requires pre-approval by the Chair of the Audit Committee of fees and expenses for other non-audit services that may arise during the year. The policy requires the Chair to report any non-audit services that the Chair has pre-approved to the Audit Committee at each regularly scheduled meeting of the Audit Committee. In no event may Deloitte perform any of the following services for us: (1) bookkeeping or other services related to our accounting records or financial statements; (2) financial information systems design and implementation; (3) appraisal or valuation services, fairness opinions, or contribution-in-kind reports; (4) actuarial services; (5) internal audit outsourcing services; (6) management functions or human resources services; (7) broker-dealer, investment advisor, or investment banking services; (8) legal services; or (9) expert services. The Audit Committee regularly considers whether specific projects or expenditures could potentially affect Deloitte’s independence.

PROPOSAL 3: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Deloitte has been our independent registered public accounting firm since 2002. The Audit Committee has engaged Deloitte to perform reviews, in accordance with the Standards of the Public Company Accounting Oversight Board, of our financial statements to be filed on Form 10-Q in 2021. Consistent with past practice, on December 14, 2020, the Audit Committee approved the engagement of Deloitte to perform the audit of the financial statements and internal controls over financial reporting included in SPX’s Annual Report on Form 10-K for the fiscal year ending December 31, 2021. Representatives of Deloitte will be present at the Annual Meeting and will have the opportunity to make a statement if they so desire and to respond to appropriate questions.

Although we are not required to do so, we believe that it is appropriate for us to request stockholder ratification of the appointment of Deloitte as our independent registered public accounting firm. If stockholders do not ratify the appointment, the Audit Committee will investigate the reasons for the stockholders’ rejection and reconsider the appointment.

QUESTIONS AND ANSWERS

Proxy Materials

Why am I receiving these materials?

We are mailing or making these materials available to you because we are soliciting your proxy to vote your shares in connection with our Annual Meeting, scheduled to take place on May 11, 2021, or at any adjournments or postponements of this meeting. We are first mailing or making available to stockholders this Proxy Statement, our Annual Report to Stockholders for the year ended December 31, 2020, and related materials on or about March 26, 2021.

Why did I receive a one-page notice of internet availability of proxy materials rather than a full set of proxy materials?

SEC rules allow companies to provide stockholders access to Proxy Materials over the internet rather than mailing the materials to stockholders. Accordingly, to conserve natural resources and reduce costs, we are sending many of our stockholders a Notice of Internet Availability of Proxy Materials. The Notice provides instructions for accessing the Proxy Materials on the website referred to in the Notice or for requesting printed copies of the Proxy Materials. The Notice also provides instructions for requesting the delivery of the Proxy Materials for future Annual Meetings in printed form.

Are the proxy materials available electronically?

Our Proxy Statement and our 2020 Annual Report to Stockholders are available on our website (www.spx.com) under the heading “Investor Relations—Financial Information—Annual Reports.” Additionally, and in accordance with SEC rules, you may access our Proxy Statement at www.envisionreports.com/SPXC (for stockholders of record) or www.edocumentview.com/SPXC (for all other stockholders), which do not have “cookies” that identify visitors to the sites.

Voting and Quorum

What is a proxy?

Our Board of Directors is asking for your proxy, which is a legal designation of another person to vote the shares you own. We have designated two officers of the Company, Eugene J. Lowe, III and James E. Harris, to vote your shares at the meeting in the way you instruct and, with regard to any other business that may properly come before the meeting, as they think best.

QUESTIONS AND ANSWERS

Who is entitled to vote?

Stockholders at the close of business on March 15, 2021 (the record date), are entitled to vote. On that date there were 45,309,380 shares of SPX common stock outstanding.

How many votes do I have?

Each share of SPX common stock that you own entitles you to one vote.

How do I vote if I do not attend the Annual Meeting?

If your shares are held in your name as a stockholder of record, then you may vote your shares before the meeting over the internet by following the instructions on the Notice of Internet Availability of Proxy Materials or proxy card you received for that account.

If your shares are held through a broker, bank, trustee, or other holder of record, then you may vote your shares before the meeting over the internet by following the instructions on the Notice of Internet Availability of Proxy Materials or proxy card you received or, if you received a voting instruction form from your brokerage firm, bank, trustee, or other similar entity by mail, then by completing, signing, and returning the form you received. You should check your voting instruction form to see if telephone or internet voting is available to you.

If you received more than one Notice of Internet Availability of Proxy Materials or proxy card, then this means you hold shares of our common stock in more than one account. You should complete, sign, date, and return each proxy card or vote all shares over the internet or by telephone for each of your accounts. If you vote over the internet or by telephone, then you should not mail back the related proxy card.

Can I vote during the Annual Meeting?

Yes. If you were a stockholder on the record date, then you can vote your shares of common stock during the Annual Meeting. If your shares are held through a broker, bank, trustee, or other holder of record, then you may vote your shares only if you have a legal proxy from the entity that holds your shares giving you the right to vote the shares. A legal proxy is a written document from your brokerage firm, bank, trustee, or other holder of record authorizing you to vote the shares it holds for you in its name. Please refer to “How do I register to attend the Annual Meeting virtually on the internet?” section above for further instructions.

Even if you currently plan to attend the meeting, we recommend that you also vote by proxy as described above so that your vote will be counted if you later decide not to attend the meeting.

May I revoke my proxy?

You may revoke your proxy in one of four ways at any time before it is exercised:

• |  | Notify our Corporate Secretary in writing before the Annual Meeting that you are revoking your proxy;

• |  | Submit another proxy with a later date;

• |  | Vote by telephone or internet after you have given your proxy; or

• |  | Vote at the Annual Meeting.

What constitutes a quorum?

The presence, directly or by proxy, of the holders of one-third of the total number of shares of SPX stock issued and outstanding and entitled to vote at the Annual Meeting constitutes a quorum. You will be considered part of the quorum if you return a signed and dated proxy card, if you vote by telephone or internet, or if you attend the Annual Meeting.

Abstentions are counted as “shares present” at the Annual Meeting for purposes of determining whether a quorum exists. Proxies submitted by brokers, banks, trustees, or other holders of record holding shares for you as a beneficial owner that do not indicate a vote for some of or all of the proposals because that holder does not have voting authority and has not received voting instructions from you (so-called “broker non-votes”) are also considered “shares present” for purposes of determining whether a quorum exists. Brokers are permitted to vote your shares on the ratification of the appointment of our independent public accountants, even if they do not receive voting instructions from you.

QUESTIONS AND ANSWERS

What vote is required to approve each proposal?

Proposal |  | Vote Required |  | Broker Discretionary Voting Allowed
Election of Directors |  | Majority of Votes Cast |  | No
Approval of Named Executive Officers’ Compensation, on a Non-binding Advisory Basis |  | Majority of Votes Cast |  | No
Ratification of Appointment of Independent Registered Public Accounting Firm |  | Majority of Shares Present or Represented by Proxy and Entitled to Vote |  | Yes
Other Proposals |  | Majority of Shares Present or Represented by Proxy and Entitled to Vote |  | No

A majority of votes cast means that the number of shares voted for a director or proposal must exceed the number of shares voted against that director or proposal.

What is the impact of abstentions or broker non-votes?

An abstention is not considered as a share voted and will not impact the election of directors or the non-binding advisory vote to approve our named executive officers’ compensation.

In addition, since an abstention is considered a share present or represented by proxy and entitled to vote, as one less vote for approval it will have the effect of a vote against the ratification of our independent public accountants and other proposals that may be brought before the Annual Meeting.

A “broker non-vote” occurs when a broker, trustee, bank, or other nominee that holds shares on your behalf does not receive instructions from you on how to vote such shares and does not otherwise have discretion to vote because the matter is not considered routine. A broker non-vote is not considered as a share voted or entitled to vote and will not impact the vote on any of the proposals.

The NYSE does not consider the election of directors or matters relating to compensation to be routine. Unless the broker has received instructions from you, any broker holding shares for you will not have the ability to cast votes with respect to the election of directors or the approval of our named executive officers’ compensation. It is important, therefore, that you provide instructions to your broker if your shares are held by a broker so that your vote with respect to these matters is counted.

How does discretionary voting authority apply?

If you sign, date, and return your proxy card, then your vote will be cast as you direct. If your proxy card does not indicate how you want to vote, then you give authority to Eugene J. Lowe, III and James E. Harris to vote on the items discussed in these proxy materials and any other matter properly brought at the Annual Meeting. In such a case, your vote will be cast:

• |  | FOR the election of the director nominees;

• |  | FOR the approval of our named executive officers’ compensation;

• |  | FOR the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2021; and

• |  | FOR or AGAINST any other properly raised matters at the discretion of Eugene J. Lowe, III and James E. Harris.

Who pays to prepare, mail, and solicit the proxies?

We will pay all the costs of preparing, mailing, and soliciting the proxies. We will ask brokers, banks, trustees, and other nominees and fiduciaries to forward the Proxy Materials to the beneficial owners of SPX common stock and to obtain the authority to execute proxies. We will reimburse them for their reasonable expenses upon request. In addition to mailing Proxy Materials, our directors, officers, and employees may solicit proxies in person, by telephone, or otherwise. These individuals will not be specially compensated. We have retained Georgeson LLC, a Computershare company, to assist us with inquiries of brokerage houses and other custodians and nominees whether other persons are beneficial owners of SPX common stock. We will supply them with additional copies of the Proxy Materials for distribution to the beneficial owners. We will pay

##### Table of Contents

QUESTIONS AND ANSWERS

Georgeson LLC an estimated fee of $1,800 plus reasonable out-of-pocket expenses. We have not retained a proxy solicitor for this Annual Meeting to assist us in soliciting your proxy; however, as proxy returns are counted we may determine it is necessary to retain a proxy solicitor, in which case we will pay an estimated fee of $12,500 plus reasonable out-of-pocket expenses.

Communications and Stockholder Proposals

How do I submit a stockholder proposal?

To bring a proposal other than the nomination of a director before an annual meeting, your notice of proposal must comply with the requirements of our By-laws and include any other information regarding you or any beneficial owner that would be required under the SEC’s proxy rules and regulations.

For a proposal to be included in our Proxy Statement for the 2022 Annual Meeting, you must submit it no later than November 26, 2021. Your proposal must be in writing and comply with the proxy rules of the SEC. You should send your proposal to our Corporate Secretary at our address on the cover of this Proxy Statement.

You also may submit a proposal that you do not want included in the Proxy Statement, but that you want to raise at the 2022 Annual Meeting. We must receive this type of proposal in writing on or after December 12, 2021, but no later than January 11, 2022.

How do I submit a director nominee?

If you wish to submit a nominee for director for the 2022 Annual Meeting, our Corporate Secretary must receive written notice of your intended nomination on or before January 11, 2022. You should send your nomination to our Corporate Secretary at our address on the cover of this Proxy Statement.

For a nomination to be properly brought before an annual meeting, your notice of nomination must comply with the requirements of our By-laws. In addition, any director nominee must provide information we may reasonably request in order for us to determine the eligibility of such nominee to serve as an independent director.

You may also make recommendations for director nominees to the Nominating and Governance Committee. Director nominations made to the Nominating and Governance Committee is more fully described in the “Director Nominees, Qualifications, and Diversity” section, beginning on page 2.

APPENDIX A – RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES

Adjusted results are non-GAAP financial measures that exclude, among other items, the effect of our South African operations. Additionally, we have made adjustments for items that are non-cash, annual incentive related, and/or unusual in nature. Lastly, and as previously discussed, the results of ULC and Sensors & Software, as well as a legacy product liability charge and COVID-19 and certain other non-recurring items, have been excluded from the annual incentive targets and the results for annual incentive purposes in 2020. This appendix to the Proxy Statement includes reconciliations of the amounts of non-GAAP financial measures with the most comparable measures determined in accordance with accounting principles generally accepted in the United States (“GAAP”) and other important information regarding non-GAAP financial measures.

Adjusted revenue for annual incentive purposes |  | $ | 1,539.3 |  |  | $ | 1,515.5 |  |  |  |  |

Adjusted revenue is defined as consolidated revenue for the Company excluding our South African operations. Due, in part, to certain wind-down activities, and the related decline in volumes, the South African operations have a diminishing impact on the Company’s operating results over the long term. As such, the Company’s management believes it is useful to investors to present revenues without the results of the South African operations to provide investors with metrics that the Company’s management uses to measure the overall performance of its businesses. In addition, the results of ULC and Sensors & Software have been excluded from the annual incentive targets and the results for annual incentive purposes in 2020.

Adjusted earnings per share |  | $ | 2.80 |  |  | $ | 2.76 |  |  |  | 1.4 | %

Adjusted operating income, adjusted net income, and adjusted earnings per share, are defined as operating income, net income from continuing operations, and diluted net income per share from continuing operations excluding the following items, as applicable: (a) results of our South African operations, (b) non-service pension and postretirement expense (income), (c) non-recurring acquisition-related charges, including charges related to the step-up of inventory, (d) income and charges related to the prior sale of the Company’s Dry Cooling business, (e) non-cash charges associated with the amendment/refinancing of our senior credit agreement, (f) amortization expense associated with acquired intangible assets, (g) gains on an equity security associated with fair value adjustments, (h) non-cash charges related to the impairment of certain acquired intangible assets, and (i) certain discrete income tax benefits, as applicable, as well as (j) the income tax impact of items (a) through (h). In addition to the Company’s South African operations, as described above, the Company’s management views the impact related to each of the other items as not indicative of the Company’s ongoing performance. The Company believes adjusted operating income, adjusted net income, and adjusted earnings per share gives investors a useful tool to assess and understand the Company’s overall financial performance, because they exclude items of income or expense that the Company believes are not reflective of its ongoing operating performance, allowing for a better period-to-period comparison of operations of the Company. Additionally, the Company’s management uses adjusted operating income, adjusted net income, and adjusted earnings per share as measures of the Company’s performance. The adjusted operating income, adjusted net income, and adjusted earnings per share measures do not provide investors with an accurate measure of the actual operating income, net income from continuing operations, and earnings per share reported by the Company and should not be considered as substitutes for operating income, net income from continuing operations, and net income per share from continuing operations as determined in accordance with GAAP, and may not be comparable to similarly titled measures reported by other companies. In addition, and as previously discussed, the results of ULC and Sensors & Software, along with a legacy product liability charge and Covid-19 and certain other non-recurring costs, have been excluded from the annual operating income incentive targets and the results for annual operating income incentive purposes in 2020.
