CEO Pay for Performance

Our executive compensation program is focused on driving sustained meaningful profitable growth and stockholder value creation. The Compensation Committee seeks to foster these objectives through a compensation system that focuses heavily on variable, performance-based incentives that create a balanced focus on our short-term and long-term strategic and financial goals. As shown in the charts, in 2025, approximately 93% of the target compensation of our Chair, President, and Chief Executive Officer was variable, with the value tied to the achievement of specified financial performance goals and stock price performance.

Corporate Governance

“The Board is highly engaged and brings rigorous, independent judgment to the oversight of CDW’s long-term strategy. Our governance framework supports effective oversight through active Board engagement, regular executive sessions, and disciplined evaluation of Board and committee effectiveness. In close partnership with management, and informed by ongoing dialogue with our stockholders, the Board remains focused on long-term value creation.”

— James A. Bell, Lead Independent Director

Corporate Governance Highlights

Annual Election of Directors. All directors are elected annually.

Lead Independent Director. Our Lead Independent Director is elected by and from the independent members of our Board.

Independent Board. Our Board is comprised entirely of independent directors, other than our Chair, who also serves as President and Chief Executive Officer. The independent members of our Board regularly meet in executive session.

Independent Board Committees. All members of our Audit, Compensation, and Nominating and Corporate Governance Committees are independent.

Audit Committee Financial Experts. All members of our Audit Committee qualify as “audit committee financial experts” as defined under US Securities and Exchange Commission (“SEC”) rules.

Stockholder Right to Call Special Meetings. Our Amended and Restated Bylaws (“Bylaws”) allow stockholders representing at least 25% of the voting power of our outstanding common stock to call special meetings, as further detailed in our Bylaws.

Stockholder Action by Written Consent. Our Board has approved a management proposal to allow stockholders to take action by written consent (Proposal 4 in this proxy statement).

Proxy Access. Our Bylaws permit a stockholder, or a group of up to 20 stockholders, owning at least 3% of our outstanding common stock continuously for at least 3 years to nominate and include in our proxy materials director nominees constituting up to 2 individuals or 20% of the Board, whichever is greater, as further detailed in our Bylaws.

Majority Vote. Directors are elected by majority votes cast in uncontested elections. We have a resignation policy that applies if a director fails to receive a majority of the votes cast.

Board Term Limit. Our Corporate Governance Guidelines provide that a director will not be renominated at the next annual meeting of stockholders after 15 years of service on our Board, absent special circumstances.

Restrictions on Other Board Service. Our Corporate Governance Guidelines require the Nominating and Corporate Governance Committee and the Board to consider directors’ and candidates’ outside time commitments, including the number of other boards they serve on. The Guidelines also limit board memberships: directors who are executive officers of a public company may serve on no more than 2 public company boards (including ours), and directors who are not executive officers may serve on no more than 4 public company boards (including ours).

Annual Board and Committee Evaluations. Our Lead Independent Director conducts one-on-one interviews with each director to assess Board performance and effectiveness. The Nominating and Corporate Governance Committee reviews and discusses the results. Each of the Audit, Compensation, and Nominating and Corporate Governance Committees also conducts an annual self-evaluation to assess Committee performance and effectiveness.

No Supermajority Vote Requirements. Our Certificate of Incorporation and Bylaws may be amended by the affirmative vote of a majority of the Company’s outstanding common stock.

No Stockholder Rights Plan. The Company does not have a stockholder rights plan or poison pill.

2026 Proxy Statement

Corporate Governance

Our success is built on the trust we have earned from our customers, coworkers, business partners, investors, and communities, and that trust sustains our success. Part of this trust stems from our commitment to good corporate governance. Our Company is governed by our Board of Directors (“Board of Directors” or “Board”). The Board is responsible for providing oversight of the strategic and operational direction of the Company and supporting the Company’s long-term interests.

To provide a framework for effective governance, our Board has adopted Corporate Governance Guidelines, which outline the operating principles of our Board and the composition and working processes of our Board and its committees. The Nominating and Corporate Governance Committee periodically reviews our Corporate Governance Guidelines and developments in corporate governance and recommends proposed changes to the Board for approval.

Our Corporate Governance Guidelines, along with other corporate governance documents such as committee charters and The CDW Way Code (our code of business conduct and ethics), are available on the Governance section of our Investor Relations website at investor.cdw.com. These documents and any other information available on our website are not part of, or incorporated by reference into, this proxy statement.

Independence of Our Board of Directors

Under our Corporate Governance Guidelines and the listing standards of the Nasdaq Global Select Market (“Nasdaq”), a majority of our Board must be independent. The Board annually determines whether each of our directors is independent. In determining independence, the Board follows the independence criteria set forth in the Nasdaq listing standards and considers all relevant facts and circumstances.

Under the Nasdaq independence criteria, a director cannot be considered independent if they have one of the relationships specifically enumerated in the Nasdaq listing standards. In addition, the Board must affirmatively determine that a director does not have a relationship that, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. The Board has affirmatively determined that each of our current directors, other than our Chair, President, and Chief Executive Officer, Christine A. Leahy, and each of the directors who served during the last completed fiscal year is independent under the applicable listing standards of Nasdaq. In making its determination, the Board considered that Ms. Grier served as US Chair and Managing Partner (CEO) of EY, the Company’s independent registered public accounting firm, until July 2022 and that Ms. Grier did not personally work on the audit of the Company by EY or provide any other services to the Company since 2014. Because Ms. Grier is retired from EY and due to the significant length of time since she last worked on the Company’s audit, the Board found that her prior relationship with EY does not interfere with the exercise of her independent judgment in carrying out her responsibilities as a director of the Company.

Board of Directors Leadership Structure

Christine A. Leahy, our President and Chief Executive Officer, serves as Chair of the Board and James A. Bell, a non-executive and independent director, serves as Lead Independent Director. The Board believes that the combined role of Chair of the Board and Chief Executive Officer of our Company, together with the appointment of a Lead Independent Director (elected by and from the independent members of the Board), the independence of all Board members other than our Chief Executive Officer, and the use of regular executive sessions of the independent directors, achieves an appropriate balance between the effective development of key strategic and operational objectives and independent oversight of management’s execution of those objectives. Our governance framework provides the Board with the flexibility needed to determine the most suitable leadership structure for the Company. The Board periodically reviews its leadership structure. As part of this review, the Board has determined that the current leadership structure — with a combined Chair and Chief Executive Officer, a Lead Independent Director, and all Board committees composed entirely of independent directors — is appropriate for the Company at this time.

Our Corporate Governance Guidelines and committee charters require that when the Chair of the Board is not an independent director, the Nominating and Corporate Governance Committee will recommend an independent director to serve as Lead Independent Director. When making determinations about our leadership structure, the Board considers many factors, including business strategy, Company performance, industry dynamics, economic and regulatory developments, results of Board and committee self-evaluations, and investor feedback. The Board also considers the composition and culture of the board, including the qualifications and experience of the Chief Executive Officer and each of the directors, the roles and responsibilities of the Board Chair and the Lead Independent Director, the composition and needs of each committee of the Board, succession planning, the advantages and disadvantages of alternative leadership structures, and how best to serve the interests of our stockholders.

Corporate Governance

Chair of the Board

Christine A. Leahy

CHAIR, PRESIDENT,
AND CHIEF
EXECUTIVE OFFICER

The Board believes that having the Company’s Chief Executive Officer serve as Chair is in the best interest of its stockholders at this time because this structure ensures a seamless flow of communication between management and the Board, in particular with respect to the Board’s oversight of the Company’s strategic direction and risk management, as well as the Board’s ability to ensure management’s focused execution of that strategy. The Board also believes that, because the Chief Executive Officer is the director most familiar with the Company’s business, industry, and day-to-day operations, she is well-positioned to help the Board focus on those issues of greatest importance to the Company and its stockholders and to assist the Board with identifying the Company’s strategic priorities, as well as the short-term and long-term risks and challenges facing the Company. While independent directors have invaluable experience and expertise from outside the Company and its business, giving them different perspectives regarding the development of the Company’s strategic goals and objectives, the Chief Executive Officer is well-suited to bring Company-specific experience and industry expertise to her discussions with independent directors. The responsibilities of the Chair include, among others:

RESPONSIBILITY		DESCRIPTION
Board Meetings		Preside at and manage all meetings of the Board
Facilitate Discussion		Support a strong Board culture by fostering an environment of open dialogue, effective information flow, and constructive feedback among the members of the Board and management, facilitating communication among the Lead Independent Director, the Board as a whole, Board committees, and management, and encouraging director participation in discussions
Agendas		Propose to the Lead Independent Director for input, the annual Board calendar, agenda items, and schedules for each Board meeting and the materials to be presented to the Board
Information		Work with the Lead Independent Director to facilitate timely and appropriate information flow to the Board
