How are the proxy materials being distributed?

To expedite delivery, reduce our costs and decrease the environmental impact of our proxy materials, we used “Notice and Access” in accordance with the U.S. Securities and Exchange Commission (“SEC”) rule that allows companies to furnish their proxy materials over the internet. As a result, we are mailing to many of our stockholders of record a notice of the internet availability of the proxy materials in lieu of a paper copy of the proxy materials.

Who is the holder of record?

You may own your shares of Common Stock either:

If your shares are registered directly in your name, you are the holder of record of these shares, and we are sending these proxy materials directly to you. If you hold your shares through an intermediary, such as a bank or broker, you must register in advance to attend the Annual Meeting, unless you plan to attend as a guest.

Frequently Asked Questions

How are votes counted?

For all matters being submitted to a vote of stockholders, only proxies and ballots that indicate votes ‘‘FOR,’’ ‘‘AGAINST’’ or ‘‘ABSTAIN’’ on the proposals, or that provide the designated proxies with the right to vote in their judgment and discretion on the proposals are counted to determine the number of shares present and entitled to vote.

A New York Stock Exchange (“NYSE”) member broker that holds shares for the account of a customer has the authority to vote on certain limited matters without instructions from the customer. Of the matters being submitted to a vote of stockholders at the Annual Meeting, NYSE rules permit member brokers to vote without instructions only on the proposal to ratify the appointment of our independent auditor. On each of the other matters, NYSE members may not vote without customer instruction. A notation by a broker on a returned proxy that it is not permitted to vote on particular matters due to the NYSE rules is referred to as a “broker non-vote.”

How will my shares be voted at the Annual Meeting?

The individuals named as proxies on the proxy card will vote your shares in accordance with your instructions. Please review the voting instructions and read the entire text of the proposals and the positions of the Board of Directors in this Proxy Statement prior to marking your vote. If your proxy card is signed and returned without specifying a vote or an abstention on a proposal, it will be voted according to the recommendation of the Board of Directors on that proposal.

BOARD COMPOSITION HIGHLIGHTS

Board Composition

Specific Skills and Attributes to be Represented on the Board

In considering each director nominee for the Annual Meeting, the Governance and Social Responsibility Committee evaluated such person’s background, qualifications, attributes and skills to serve as a director. The Board and the Governance and Social Responsibility Committee considered the nomination criteria discussed below, as well as the years of experience many directors have had working together on the Board and the deep knowledge of the Company they have developed as a result of such service. The Board and the Governance and Social Responsibility Committee also evaluated each of the director’s contributions to the Board and role in the operation of the Board as a whole, as applicable.

Our Board did not assign specific weights to any of these attributes or otherwise formally rate the level of an attribute possessed by any director relative to any other person. If a skill is not attributed to a director in the following table, it does not necessarily mean that the director does not possess that attribute; it means only that when the Board considered that nominee in the overall context of the composition of our Board of Directors, that attribute was not a key factor in the determination to nominate that individual.

PROCESS FOR SELECTING DIRECTORS

The Board is responsible for recommending director nominees to the stockholders and for selecting directors to fill vacancies between stockholder meetings. One of the responsibilities of the Governance and Social Responsibility Committee is to identify and recommend to the Board candidates for election as directors. The committee considers candidates suggested by its members, other directors, senior management and stockholders as necessary in anticipation of upcoming director elections or due to Board vacancies. On occasion, the Governance and Social Responsibility Committee has engaged external search firms to facilitate nationwide candidate searches as part of its refreshment efforts.

Each of the directors nominated for election at the Annual Meeting were evaluated and recommended to the Board for nomination by the Governance and Social Responsibility Committee and nominated by the Board for election.

All director candidates, including those recommended by stockholders, are evaluated on the same basis. Candidates are considered in light of the entirety of their credentials. As part of the evaluation of individual candidates, the following factors are taken into consideration:

Board Composition

Board Diversity Policy

The Board is committed to having a membership that reflects diverse perspectives, skills, geographic and cultural backgrounds, and experiences in areas relevant to the Company’s global operations. The Board has adopted a policy, included in the Corporate Governance Guidelines, formalizing its longstanding commitment to maintaining a gender and ethnically diverse Board.

The Governance and Social Responsibility Committee identifies and adds new directors using the following process.

Establish and Refresh Candidate Pool using:   •  Independent search firms •  Independent director recommendations •  Stockholder recommendations

Initial Candidate Review by Governance and Social Responsibility Committee:   The Governance and Social Responsibility Committee and senior management review the qualifications and expertise of initial pool of candidates to determine which candidates warrant further consideration.   Due diligence is conducted by third parties, including soliciting feedback from other directors and applicable persons outside the Company.

Governance and Social Responsibility Committee and Director Evaluation:   Candidates warranting further consideration are comprehensively reviewed and extensively discussed during Governance and Social Responsibility Committee meetings, with detailed updates provided to the Board throughout the process.   The candidates that emerge from this process are interviewed by members of the Governance and Social Responsibility Committee, as well as other Board members, including the Chair.   During these meetings, directors assess candidates on the basis of their skills and experience, their personal attributes and their expected contribution to the diversity of skills, experiences and backgrounds on our Board.

Recommendation to the Board:   The Governance and Social Responsibility Committee then makes its recommendation to the Board, which include detailed feedback from candidate interviews and other relevant information.

Director Onboarding

The Company maintains a comprehensive director onboarding program. All new directors participate in our director orientation program during the first few months on our Board. New directors receive an extensive suite of onboarding materials covering director responsibilities, corporate governance practices and policies, business strategies, leadership structure, and long-term plans. They then participate in a series of meetings with management representatives from our business and functional areas to review and discuss information about the Company’s strategic plans, financial statements, and key issues, policies, and practices. Based on feedback from our directors, we believe this onboarding approach provides new directors with a strong foundation for understanding our businesses, connects directors with members of management with whom they will interact, and accelerates their effectiveness to engage fully in Board deliberations.

Board Composition

Director Education

Our director education program assists Board members in fulfilling their responsibilities. In addition to the onboarding program, when a director joins the Board, ongoing education is provided through in-depth presentations on topics such as strategy, operations, the energy transition, cybersecurity, ESG related issues, enterprise risk management, DEI, and legal and regulatory matters. These presentations can be from management or with outside experts as needed. We also reimburse directors who attend continuing director education programs for fees and related expenses. The Board periodically holds board meetings at various offices and locations important to the business where directors engage with employees in a more informal setting.

Annual Board Evaluation Process

The Governance and Social Responsibility Committee oversees an annual performance evaluation of our Board, Chair, Director and Board Committees, including the Committee Chairs. As part of this process, our directors evaluate the performance of their peers serving on the Board, providing candid feedback to enable continuous boardroom improvement and assist with director succession planning. Our Board views the evaluation process as integral to assessing its effectiveness and identifying improvement opportunities in the pursuit of continued excellence.

Below is a summary of our Board evaluation process.

Board Composition

Director Independence

In accordance with NYSE listing standards (the “NYSE Listing Standards”), the Board annually evaluates the independence of each member of the Board of Directors under the independence standards set forth in Interpublic’s Corporate Governance Guidelines, and under the NYSE Listing Standards.

Interpublic has ten directors, one of whom, Philippe Krakowsky, is an employee of Interpublic and, nine of whom are not employees of Interpublic or its subsidiaries (referred to in this Proxy Statement as “Non-Management Directors”). At their meetings held in February of this year, the Governance and Social Responsibility Committee and the full Board determined that each of the Non-Management Directors is an independent director under Interpublic’s Corporate Governance Guidelines and the NYSE Listing Standards.

Meeting of Independent Directors

The NYSE Listing Standards require that if the group of Non-Management Directors includes one or more directors who are not independent, then at least once annually, the Non-Management Directors should hold an executive session attended by only independent directors. Although not required under the NYSE Listing Standards (because all of the Non-Management Directors are independent), the Board nevertheless held several executive sessions of its independent directors during 2023, with Mr. Thomas serving as the chair of the sessions.

BOARD LEADERSHIP STRUCTURE

Our Corporate Governance Guidelines permit the roles of Chair of the Board and Chief Executive Officer to be filled by the same or different individuals, based on our needs, best practices and the interests of our stockholders. This allows the Board flexibility to determine whether the two roles should be combined or separated based upon our needs and the Board’s assessment of its leadership from time to time, believing that the best leadership structure may vary as circumstances warrant. After careful consideration, the Board made a determination that an independent Chair would be the most appropriate Board leadership structure at this time. David Thomas has served as non-executive Chair since January 1, 2022.

Mr. Thomas, who is independent in accordance with SEC and NYSE rules, presides at meetings of our stockholders and directors and leads the Board in fulfilling its responsibilities. The Board benefits from Mr. Thomas’ extensive and diversified leadership, and financial management experience. He also has strong public company board experience and has intimate familiarity with our history and business, having served as the Board’s Presiding Director since 2013 and serving on the Board since 2004.

The Board believes that the corporate governance measures it has in place ensure that strong, independent directors effectively oversee our management and provide vigorous oversight of our key issues relating to strategy, risk and integrity.

The Board believes the current structure provides an appropriate degree of oversight and allows Mr. Krakowsky, our Chief Executive Officer, to focus on the operational and strategic objectives of the Company. This structure also enhances the information flow between management and the Board, which are essential to effective governance, and ensures the continuity of efficient and effective leadership, which is in the best interests of Interpublic and our stockholders.

Non-Executive Chair

The independent, non-executive Chair of the Board helps to coordinate communications between the Board and management of Interpublic. In this role, the non-executive Chair

Our corporate governance framework is designed to ensure strong commitment to maintaining sound corporate governance practices enabling independent and skilled directors to provide oversight, advice, and counsel to promote the interests of Interpublic and its stockholders and stakeholders. Key governance policies and processes include our Code of Conduct, our comprehensive enterprise-wide risk management program, our commitment to transparent financial reporting and our systems of internal checks and balances.

To do so effectively, our Board along with management regularly reviews our Corporate Governance Guidelines, our committee charters and governance practices to assure that they are appropriate and reflect high standards.

INTERPUBLIC GOVERNANCE HIGHLIGHTS

Corporate Governance Framework

Human Capital Management and Succession Planning

Interpublic’s Board of Directors is actively involved in talent management. Annually, the Board reviews and analyzes the alignment of Interpublic’s strategy on personnel and succession with its overall business strategy. This includes a detailed discussion of Interpublic’s global leadership bench, strength and succession plans with a focus on key positions at the senior officer level. In addition, the committees of the Board regularly discuss the talent pipeline for specific critical roles at Interpublic and each of its global agencies. One of the principals of our comprehensive succession planning effort is the cultivation of a workforce that is diverse and a climate of inclusion that promotes the development, advancement and well-being of our key talent.

The Board seeks opportunities to provide potential leaders with exposure and visibility to Board members through formal presentations and by periodically holding Board and committee meetings at key operating units. In addition, the Board is regularly updated on key talent indicators for the overall workforce, including work environment, diversity, recruiting and development programs.

Code of Conduct

Interpublic has adopted a set of ethical standards known as the Code of Conduct, which applies to all employees of Interpublic and its subsidiaries and affiliates. Interpublic’s Corporate Governance Guidelines provide that members of the Board of Directors and officers (which includes Interpublic’s Chief Executive Officer, Chief Financial Officer, Controller and Chief Accounting Officer and other persons performing similar functions) must comply with the Code of Conduct. In addition, the Corporate Governance Guidelines state that the Board will not waive any provision of the Code of Conduct for any director or executive officer. The Code of Conduct, including future amendments, may be viewed on Interpublic’s website at http://www.interpublic.com or a copy may be obtained free of charge by writing to The Interpublic Group of Companies, Inc., 909 Third Avenue, New York, NY 10022, Attention: SVP & Secretary.

Risk Oversight and Management

Board Risk Oversight

Our Board actively oversees Interpublic’s risk management activities both directly and through its committees. The Board considers various risk topics throughout the year, including risks associated with our strategic plan, business and operations, information technology (including cybersecurity), acquisition and capital allocation program, and capital structure and liquidity, among many others. The Board also oversees the Company’s risk assessment and risk management policies and performs an annual review and assessment of the primary operational and regulatory risks facing Interpublic, their relative magnitude and management’s plan for mitigating these risks. Reports from each committee chairperson are given to the Board at each regular Board meeting regarding the applicable committee’s considerations and actions, as well as reports from senior leaders across the organization who are responsible for oversight of particular risks within the Company, as necessary. Additionally, the Board periodically visits certain of our principal operating units in and outside the U.S., which provides the directors with an opportunity to observe the Company’s operations and to interact with employees outside of the boardroom.

Cybersecurity Risk Oversight

One of the primary responsibilities of our Board is to oversee Interpublic’s cybersecurity and information security risk management and controls. Throughout the year, our Chief Information Officer provides the Board and the Audit Committee

Corporate Governance Framework

with reports addressing a broad range of topics, including updates on policies and practices, industry trends, and ongoing efforts to prevent, detect, and respond to internal and external critical threats. Our Chief Information Officer and Chief Information Security Officer together work closely with key stakeholders, including internal committees such as the information security steering committee, peer institutions, and industry groups, in order to manage cybersecurity and information security risk. Interpublic maintains, and we require our third-party service providers to maintain, security controls designed to ensure the confidentiality, integrity, and availability of our systems and the confidential and sensitive information we maintain and process, or which is processed on our behalf. Additionally, Interpublic’s employees are required to complete trainings that cover security and privacy best practices and company policies.

Committee Risk Oversight

Each of the Board’s committees assists the Board in fulfilling its role by overseeing the risks in areas over which they have responsibility.

Management Risk Oversight

Interpublic’s senior management is responsible for assessing and managing the Company’s various exposures to risk on a day-to-day basis, including the identification of risks through a robust enterprise risk management framework and the creation of appropriate risk management programs and policies to address such risks. Our Executive Risk Committee which is comprised of senior leaders across the organization has primary responsibility for overseeing the risk framework, and identifying our overall risk appetite, and the material risks facing our company. Management regularly reports to the Audit Committee on a variety of significant risks facing the Company. To learn more about these risks, you can review Item 1A. Risk Factors in the 2023 Annual Report on Form 10-K. The risks described in the Form 10-K are not the only risks facing the Company. Additional risks and uncertainties also may materially adversely affect the company’s business, financial condition, or results of operations in future periods.

TRANSACTIONS WITH RELATED PERSONS

Interpublic’s Code of Conduct requires directors and employees to avoid activities that could conflict with the interests of Interpublic, except for transactions that are disclosed and approved in advance. Interpublic has adopted a Related Person Transaction Policy under which approval is required for any transaction, agreement or relationship between Interpublic or any of its consolidated subsidiaries and a Related Person (a “Related Person Transaction”).

Under the Related Person Transaction Policy, a “Related Person” is defined as any (i) director, nominee for election as a director, an executive officer or any of their “immediate family members” (as defined by the Related Person Transaction Policy); (ii) any entity, including not-for-profit and charitable organizations, controlled by or in which any of the foregoing persons have a substantial beneficial ownership interest; or (iii) any person who is known to be, at the time of the transaction, the beneficial owner of more than 5% of the voting securities of Interpublic or an immediate family member of such person.

Under the policy, Related Person Transactions do not include any employee benefit plan, program, agreement or arrangement that has been approved by the Compensation Committee or recommended by the Compensation Committee for approval by the Board.

To facilitate compliance with the policy, the Code of Conduct requires that employees, including directors and executive officers, report circumstances that may create or appear to create a conflict between the personal interests of the individual and the interests of Interpublic, regardless of the amount involved, to Interpublic’s Corporate Compliance department using Interpublic’s Conflict of Interest Disclosure Form. Each director and executive officer annually confirms to the Company his or her compliance with the Related Person Transaction Policy as part of the preparation of Interpublic’s Annual Report on Form 10-K and its annual proxy statement. Director nominees and persons promoted to executive officer positions must also confirm such compliance at the time of their nomination or promotion. Management also reviews its records and makes additional inquiries of management personnel and, as appropriate, third parties and other sources of information for the purpose of identifying Related Person Transactions, including Related Person Transactions involving beneficial owners of more than 5% of Interpublic’s voting securities.

The Audit Committee reviews transactions subject to the Related Person Transaction Policy and determines whether to approve or disapprove those transactions, by examining whether the transactions are fair, reasonable and within Interpublic policy. The Audit Committee makes its determination by considering all relevant factors and any controls that may be implemented to protect the interests of Interpublic and its stockholders. Among the factors that the Audit Committee evaluates in determining whether a transaction is fair and reasonable, as applicable, are the following:

No director may participate in any consideration or approval of a Related Person Transaction with respect to which they or any of their immediate family members is the Related Person. Related Person Transactions not approved or ratified as required by the Related Person Transaction Policy are subject to termination by Interpublic. If the transaction has been completed, the Audit Committee will consider if rescission of the transaction is appropriate and whether disciplinary action is warranted.

Related Person Transactions

Since January 1, 2022, there have been no transactions involving a Related Person identified in the responses to the annual questionnaire sent to each director and executive officer of Interpublic or that otherwise are known to the Audit Committee or Interpublic.

DIRECTOR SHARE OWNERSHIP GUIDELINES

Each Non-Management Director is expected, within 5 years of joining the Board, to accumulate a minimum share ownership in Interpublic stock equal to five times the annual cash retainer paid to Non-Management Directors. Outstanding shares of restricted stock are included in a director’s share ownership. All Non-Management Directors standing for re-election as of

December 31, 2023, have met or exceeded these guidelines, other than Mr. Benitez who was elected to the Board on September 1, 2023.

This section describes how IPG embraces corporate values centered around our ESG Strategic Priorities. These priorities are covered in-depth in our ESG Report, which is found here: https://esg.interpublic.com/, and include:

DIVERSITY, EQUITY AND INCLUSION ARE ESSENTIAL TO CREATING LONG TERM VALUE

At IPG, we are deeply committed to advancing Diversity, Equity and Inclusion in our workplace, our industry and the markets in which we operate. We believe that it is critical for us to build a workforce that reflects the rich diversity of our global communities and consumers. Our people are at the heart of everything we do. This is why we believe that cultivating an inclusive culture that centers equity and fosters diversity allows us to be at our best every day, driving a competitive advantage, growth and innovation. We believe an inclusive environment where everyone feels a true sense of belonging is essential to helping our clients make authentic and responsible connections with their customers.

As we continue to face a fast-changing world, IPG remains steadfast in cultivating an inclusive work environment that fosters a sense of belonging, wellbeing and flexibility. In 2023, we faced geo-political conflicts, socio-economic challenges, climate crises, global health uncertainties and a volatile economy. As the world continues to embrace new ways of working, IPG focused on leveraging the tenets of our inclusive culture to maintain employee connection, prioritizing work-life harmony, and closely monitoring employee engagement and satisfaction. In 2023, these commitments allowed us to navigate the rapidly changing talent market and differentiate ourselves as a true human-centered organization.

LEADERSHIP COMMITMENT AND ACCOUNTABILITY ON DIVERSITY

The Role of Leadership

IPG has taken the lead as an advertising holding company in pushing for a more inclusive and diverse industry. IPG was the first in our industry to appoint a Chief Diversity Officer and the first to release race and gender composition of U.S. employees. We value accountability which includes transparency, leadership engagement and the resources required to advance this work. This long-standing commitment continues as we appointed a new Chief Diversity & Social Impact Officer in 2022. This redefined role, which reports directly to IPG’s CEO, is a core member of the executive leadership team and is responsible for building a global vision and strategy that will lead IPG to building an even more diverse, inclusive and equitable workforce and workplace.

The IPG Board of Directors remains engaged with and committed to the progress on diversity metrics and performance against goals each year at the holding company and our agencies. The Chief Diversity & Social Impact Officer regularly presents status updates to the Board, as well as to other members of management. The directors also seek diverse candidates of varied experiences, industries, and backgrounds to join the Board. Four of the Board’s current members identify as women and one member of the Board is African American. Agencies have high priority objectives (HPO’s) that are tied to performance, diversity goals, talent-related practices and inclusive cultures. Incentive compensation is tied to quantitative metrics and qualitative assessments of their initiatives. Agencies across the holding company have invested in building out culture, and diversity and inclusion teams that create annual strategies and goals tied to advancing this work; these goals are regularly reviewed by CEOs and leadership teams.

Inclusive Sourcing and Business Partner Diversity - Business diversity is a strategic corporate initiative at IPG and a core element of our overall commitment to diversity. IPG is committed to working with suppliers and partners who reflect the diversity of our world, our stakeholders and our clients’ customers. A diverse supplier base gives IPG a competitive advantage and helps to improve lives in our communities and around the world. To that end, we actively seek out and provide opportunities for companies owned by women, racial and ethnic minorities, veterans, LGBTQ+ people and people with disabilities.

Our progress in doing business with more underrepresented and economically disadvantaged communities is an important metric. In 2021, IPG Mediabrands and MAGNA launched a first-of-its-kind Equity Upfront initiative to raise visibility for Black-owned

Our Values

media businesses. IPG partners with leading certification organizations that represent those communities, and several of our agencies are involved with Free the Work, a not-for-profit organization dedicated to providing opportunities for women and people of color to direct and support production for advertising campaigns.

INITIATIVES FOR INCLUSIVE LEARNING, COLLABORATION AND ACTION

IPG and our agencies provide many programs in support of diversity, equity and inclusion. Through events, training, curated and bespoke content, research and tools, IPG educates to foster awareness and action on an array of critical issues that are vital for the recruitment, retention, advancement, well-being and belonging of people from historically underrepresented groups. IPG and our agencies offer many programs and resources. Examples of the topics IPG addresses include:

Business Resource Groups - IPG’s business resource groups (BRGs) provide support and networking opportunities for our employees. In 2022, we saw the emergence of even more employee resource groups across our agencies globally that support local employees and regions. In 2023, IPG reignited its BRGs with the goal to grow and amplify their impact to the business in the areas that are most important to the company and its stakeholders. IPG BRGs receive funding and support for critical programs from the corporate diversity, equity and inclusion team and our agencies. IPG BRGs serve all employees across all agencies, and they include:

VALUES-DRIVEN POLICIES AND PRINCIPLES

Anti-Harassment and Equal Employment Policy ensures a fair, ethical and respectful work environment that provides equal employment opportunities to all employees and applicants for employment without regard to race, color, religion, creed, national origin, gender, sexual orientation, age, gender identity, marital status, citizenship, disability, genetic information or veteran status or any other basis prohibited by applicable federal, state or local law.

Board Diversity Policy formalizes our longstanding commitment to maintaining a gender and ethnically inclusive board that reflects diverse perspectives, skills, geographic and cultural backgrounds as well as experiences in areas relevant to our global operations. 40 percent of IPG’s board members are women. This level of gender diversity is an important component of our overall program to ensure equity and inclusion at our company.

Code of Conduct sets expectations for a work environment that embodies respect and dignity for all employees globally. The Code makes clear our policies that prohibit discrimination based on gender identity, race, ethnicity, nationality, religion, age, sexual orientation, disability and other dimensions of diversity. Our Code also sets out our zero-tolerance policies against harassment of all types including sexual and racial harassment. Annual training reinforces these expectations, and we have a very high level of participation in this training across the company.

Supplier Code of Conduct sets forth the values and standards to which we hold our suppliers. These include an expanded statement of commitment on how our suppliers can contribute to a more sustainable world. It also includes an expanded statement of commitment to Business Diversity.

Our Values

Global Contributions Strategy and Policy ensures that our charitable donations reflect IPG’s values and business strategy and that donations are made in compliance with applicable laws. As outlined in the policy, IPG strategically engages in initiatives that support the UN Sustainable Development Goals (SDGs) and prohibits donations to organizations that support discrimination, religion, bribery or political and lobbying activity.

Domestic and International Travel Policies are updated to encourage more sustainable business travel.

Environmental Sustainability Policy is an updated policy that focuses on our commitment to the highest environmental standards and fulfillment of our responsibility on climate action, protecting natural resources, limiting pollution and being transparent about our progress. The Policy establishes best practices for IPG and individual employees to reduce our impact on the environment.

Employee and Family Leave Policy offers a minimum of 12 weeks of leave at 100% pay for all employees globally, including primary and secondary caregivers. This can be applied to parental leave as well as to care for a spouse or parent. Some of our agencies and IPG offer unlimited PTO.

Human Rights Policy codifies IPG’s commitment to the highest ethical standards and fulfillment of our social responsibilities, specifically with regards to adhering to a set of values centered around respect for every individual and appreciation for universal principles of human rights.

IPG’s Physical & Environmental Security Policy covers the handling of sensitive data, and we also maintain policies and procedures to comply with privacy and data security laws and regulations, such as the General Data Protection Regulations (GDPR) of the European Union and UK, the California Consumer Privacy Act (CCPA), and other privacy and data protection regulations across the markets in which we operate.

Responsible Media and Content Principles are based on the understanding that our companies are responsible for creating some of the world’s most recognizable marketing campaigns, and we expect such work to support the long-term well-being of our communities and our planet.

ESG REPORTING

IPG publishes progress on all our ESG strategic priorities in one, comprehensive ESG report. This report includes the measurement of our emissions and other environmental impacts using GHG Protocol Corporate Standards at all of our buildings around the world. We track energy use and greenhouse gas emissions and publish our data via the Global Reporting Initiative (GRI). IPG responds annually to the CDP and was the first U.S.-based holding company to become a signatory of the United Nations Global Compact. In 2020, IPG became the first company in our industry, globally, to report within the SASB framework. And, in 2021, we became the first U.S.-based advertising holding company to disclose in accordance with TCFD (Task Force on Climate-related Financial Disclosures) recommendations, and the first US-based advertising holding company to receive limited external assurance on certain ESG data, including selected GHG emissions and selected EEO-1 data.

CLIMATE TARGETS

IPG is committed to reaching net-zero carbon across our operations by 2040 and to sourcing 100% renewable electricity by 2030. To reach these goals, we have set near-term targets to reduce our scopes 1 and 2 emissions by 50%, and our scope 3 emissions by 30%, by 2030. These targets have been validated by the Science Based Targets initiative, the best-practice framework for validating emissions reduction targets.

SUPPORTING UNITED NATIONS SUSTAINABLE DEVELOPMENT GOALS

IPG is an active supporter of the UN Sustainable Development Goals (SDGs). These 17 global goals are part of the 2030 Agenda for Sustainable Development. IPG has specifically adopted SDG #6: access to water and sanitation for all. As part of this commitment, IPG has partnered with charity: water on several initiatives that bring water to those around the world, with the understanding that when a community gains access to water, many things begin to change for the better, including greater access to education for women and girls as well as better health in communities overall. Our ESG Report maps our work to the SDGs.

Non-Management Director Compensation

DIRECTOR COMPENSATION TABLE

The following table shows the compensation paid to Non-Management Directors for 2023⁽¹⁾.

The Audit Committee is responsible for the appointment, compensation, retention and oversight of Interpublic’s independent registered public accounting firm. As part of these responsibilities, the Audit Committee reviews the independence and performance of the independent accounting firm in connection with the Audit Committee’s determination of whether to engage another auditor as Interpublic’s independent accounting firm, and is involved in the selection of the independent accounting firm’s lead engagement partner.

The Audit Committee and the Board believe that it is in the best interests of Interpublic and our stockholders to retain PricewaterhouseCoopers to serve as our independent registered public accounting firm. In light of this, the Audit Committee has appointed PricewaterhouseCoopers LLP (“PricewaterhouseCoopers”) as Interpublic’s independent registered public accounting firm for 2024. This firm has been Interpublic’s independent accounting firm since 1952.

A representative of PricewaterhouseCoopers is expected to be present at the Annual Meeting and will have the opportunity to respond to appropriate questions. Stockholder approval of the appointment of PricewaterhouseCoopers is not required, but the Audit Committee and the Board are submitting the selection of PricewaterhouseCoopers for ratification to obtain our stockholders’ views. If a majority of the stockholders do not ratify the selection of PricewaterhouseCoopers as the registered public accounting firm to audit our financial statements for the fiscal year 2024, the Audit Committee and the Board will consider the voting results and evaluate whether to select a different independent auditor.

Item 2. Appointment of Registered Public Accounting Firm

Fees Paid to PricewaterhouseCoopers

The following is a summary and description of the fees for services provided by PricewaterhouseCoopers in 2022 and 2023.

(A) Audit Fees: Consists of fees and out-of-pocket expenses billed for professional services rendered for the audit of Interpublic’s consolidated financial statements and the audit of the effectiveness of Interpublic’s internal control over financial reporting, for review of the interim consolidated financial statements included in quarterly reports and for services that are normally provided by PricewaterhouseCoopers in connection with statutory and regulatory filings or engagements and attest services, except those not required by statute or regulation.

Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Auditor

The Audit Committee has established policies and procedures regarding pre-approval of all audit and permissible non-audit services provided by the independent accounting firm and is responsible for the audit fee negotiations associated with the engagement of the independent accounting firm. The permissible non-audit services include the services described above for which we paid Audit Related Fees, Tax Fees and All Other Fees. Under the policy, pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and is subject to a specific budget. In addition, the Audit Committee may pre-approve particular services on a case-by-case basis. The Audit Committee has delegated pre-approval authority to the Committee’s Chairperson for projects less than $200,000, who must then report any such decision to the Audit Committee at the next scheduled meeting.

The Board of Directors recommends a vote “FOR” the ratification of the appointment of PricewaterhouseCoopers as Interpublic’s independent registered public accounting firm for 2024.

The Audit Committee operates under a written charter adopted by the Board. The Board has determined that each member of the Committee is independent and financially literate under the listing standards of the NYSE and satisfies the financial expertise requirements of the NYSE. The Board has also determined that each member of the Audit Committee has the requisite experience to be designated an “audit committee financial expert” as that term is defined under applicable SEC rules and regulations.

In accordance with its written charter, the primary function of the Audit Committee is to assist the Board of Directors in its oversight of Interpublic’s financial reporting process.

Management is responsible for Interpublic’s consolidated financial statements and overall reporting process, including the establishment of a system of internal controls over financial reporting. PricewaterhouseCoopers, Interpublic’s independent registered public accounting firm, is responsible for conducting annual audits and quarterly reviews of Interpublic’s consolidated financial statements and expressing opinions as to the conformity of the annual consolidated financial statements with generally accepted accounting principles and the effectiveness of Interpublic’s internal control over financial reporting.

In performing its oversight function for the year ended December 31, 2023, the Audit Committee:

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in Interpublic’s Annual Report on Form 10-K for the year ended

February 15, 2024

In accordance with a federal securities law requirement, enacted as part of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and related SEC rules, we are submitting to an advisory vote of stockholders the compensation of our named executive officers as disclosed in the Compensation Discussion & Analysis, the compensation tables, and the narrative discussion set forth on pages 36 to 68 of this Proxy Statement. In addition to complying with this legal requirement, the Board recognizes that providing stockholders with an advisory vote on named executive officer compensation may produce useful information on investor sentiment with regard to the Company’s executive compensation programs.

At our annual meeting of stockholders held in May 2023, a substantial majority of our stockholders voted on an advisory basis to approve the compensation received by our named executive officers in calendar year-end 2023. The Compensation Committee believes this reflects stockholders’ support of the Company’s approach to executive compensation.

As described in the Compensation Discussion & Analysis section of this Proxy Statement, our compensation programs and underlying principles, as developed and administered by the Compensation Committee, are designed to provide a competitive level of compensation necessary to attract, motivate and retain talented and experienced executives who are crucial to our long-term success. The compensation paid to our named executive officers reflects our commitment to pay for performance and includes long-term cash and equity awards that are designed to encourage management to achieve results to the mutual benefit of stockholders and management. Moreover, a significant portion of our named executive officers’ annual cash compensation is paid in the form of annual performance-based incentives, which are contingent on the Company’s achievement of pre-defined performance objectives.

We encourage you to carefully review the Compensation Discussion & Analysis beginning on page 36 of this Proxy Statement for additional details on Interpublic’s executive compensation, including Interpublic’s compensation philosophy and objectives, as well as the processes our Compensation Committee used to determine the structure and amounts of the compensation paid to our named executive officers in calendar year-end 2023. The Compensation Committee and the Board believe that these policies and procedures are effective in implementing our compensation philosophy and in achieving its goals.

We are asking you to indicate your support for the compensation of our named executive officers as described in this Proxy Statement. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this Proxy Statement. Accordingly, we are asking you to vote, on an advisory basis, “For” the approval of the compensation of our named executive officers as described in this Proxy Statement, with the following non-binding and advisory resolution to be presented at the Annual Meeting:

“RESOLVED, that the compensation paid to the named executive officers of The Interpublic Group of Companies, Inc., as described in the Compensation Discussion & Analysis, compensation tables and narrative discussion set forth on pages 36 to 68 of this Proxy Statement, is hereby approved.”

While the results of this advisory vote are not binding, the Compensation Committee will consider the outcome of the vote in deciding whether to take any action as a result of the vote when making future compensation decisions pertaining to named executive officers.

The Board of Directors recommends that you vote “FOR” the approval, on an advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement.
