Dear Fellow Stockholder:

We invite you to join the Board of Directors and our management team at the ACCO Brands Corporation Annual Meeting of Stockholders, which will be held at 9:30 a.m. Central Time on Tuesday, May 19, 2026. The sole purpose of the meeting is to consider the matters described in the following Notice of 2026 Annual Meeting and Proxy Statement.

This year's Annual Meeting of Stockholders will again be conducted virtually, via a live audio webcast. By conducting our meeting virtually, we provide our broad stockholder base with easier access and greater ability to attend and participate in the meeting, including the ability to ask questions and vote their shares at the meeting if they wish.

In 2025, despite demand challenges globally and tariff-related disruptions in the U.S., ACCO Brands maintained or grew its market position in most categories, demonstrating the resilience and strength of our brand portfolio.

Our team responded quickly to U.S. tariffs and trade disruptions; our pro-active approach mitigated many of the negative impacts to our business. This work also enabled us to have an ongoing flexible supply chain with competitive costs, value added products and category leading service levels to customers.

We continued the solid implementation of our $100 million multi-year cost reduction program, which yielded $35 million in savings in 2025. Since inception of the plan in 2024, more than $60 million in savings have been realized. This program has simplified the organization, delayered our management structure and rationalized our global footprint through a reduction of our manufacturing facilities. We are on track to deliver the balance of the $100 million in savings by the end of 2026.

We continue to invest in higher growth categories as we reposition the Company for improved revenue performance. We have refined the Company's strategy to focus on the growing technology peripherals market. The acquisition of EPOS represents the first strategic move in this initiative. EPOS provides premium audio solutions and strengthens our enterprise computer accessories business.

We are confident in our strategy and our ability to execute. We are building a more focused, efficient and growth-oriented company. Our operational excellence and sound financial position, combined with our strategy to broaden into technology peripherals, creates multiple pathways to drive value creation for shareholders and a strong platform to support growth initiatives.

We thank you for your continued support of ACCO Brands and encourage you to vote your shares prior to the Annual Meeting.

It is important that your shares are represented at the meeting. You can submit your proxy by using a toll-free telephone number, by mail, or through the Internet. Instructions for using these services are provided on the accompanying proxy card. If you decide to vote your shares using the accompanying proxy card, we urge you to complete, sign, date and return it promptly.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

Board of Directors

Our By-laws currently provide that the Board of Directors may consist of not less than eight nor more than thirteen members. Currently, there are nine members serving on our Board of Directors. The Board of Directors, upon recommendation from the Nominating, Governance and Sustainability Committee, has selected all of the currently serving directors as nominees for election as directors at the Annual Meeting. Following the Annual Meeting, the Board will have nine members.

## Board Composition
**Experience, Qualifications and Skills Represented on Our Board of Directors**

Our Board of Directors has identified particular expertise, qualifications and skills that are important to be represented on our Board as a whole in order to guide our Company's long-term strategy and enhance stockholder value. As shown in the table below, as a group, the members of the Board of Directors reflect the diverse mix of skills, experiences, backgrounds, and perspectives that the Board believes is optimal to foster an effective decision-making environment. The table below is intended to highlight the specific, unique characteristics which led to each individual's selection as a nominee and the collective strength of our Board's experience and expertise.

**Board Representation**

Our goal is a balanced and diverse Board, whose members collectively possess the skills, backgrounds and experiences needed to guide the Company's long-term strategy and create

ACCO BRANDS \| 2026 PROXY STATEMENT **7**

------

stockholder value. We believe that diversity of thought, viewpoint and expertise enhance the quality of Board deliberations and decision-making.

When considering director qualifications, the Board of Directors and the Nominating, Governance and Sustainability Committee evaluate each director's credentials holistically, focusing on their individual merit, skills and potential contributions to the Board's collective expertise. We seek directors with varying tenure to balance institutional knowledge with fresh perspectives.

The Nominating, Governance and Sustainability Committee evaluates the current composition of the Board to ensure it reflects a complementary mix of viewpoints, skills, and experiences that align with the evolving needs and strategic objectives of the Company. When vacancies arise, we aim to identify and consider a broad pool of qualified candidates with diverse professional backgrounds and experiences. Depending on the current composition of the Board of Directors, the Nominating, Governance and Sustainability Committee may weigh certain factors more or less than others when ultimately selecting a director nominee.

Our director selection process is designed to build a better Board that can effectively oversee management, navigate complex business challenges and represent the interests of all stakeholders. We believe this approach to board composition enhances our corporate governance and supports the Company's long-term success in a competitive global marketplace.

Three of our nine director nominees are women and two director nominees have ethnically diverse backgrounds.

## Director Qualifications and Nomination Process
Directors are responsible for overseeing the Company's business consistent with their fiduciary duties to stockholders. The Board of Directors believes that there are general requirements applicable to all directors as well as other skills and experience that should be represented on our Board as a whole, but not necessarily in each director. The Board of Directors and the Nominating, Governance and Sustainability Committee consider a variety of factors, including the entirety of the qualifications of directors and director nominees individually, as well as in the broader context of the Board's overall composition, the Company's strategy and the current and future needs of the Board and the Company.

Among the factors considered are the potential director's judgment, independence, diversity, business and educational background, experience, stature, public service, absence of conflicts of interest,

**8** ACCO BRANDS \| 2026 PROXY STATEMENT

integrity, ethics and ownership of Company stock, as well as his or her level of commitment to stockholder value creation and his or her ability and willingness to devote sufficient time to serve on the Board of Directors. The Board of Directors and the Nominating, Governance and Sustainability Committee require that each director be a recognized person of high integrity with a proven record of success in his or her field.

In identifying and evaluating director candidates for recommendation as nominees to the Board of Directors, the Nominating, Governance and Sustainability Committee will determine, among other things, whether there are any evolving needs of the Board of Directors and the Company that require a director with particular expertise, experience or background to fill that need. The Nominating, Governance and Sustainability Committee may retain a third-party search firm to locate and provide information on candidates that meet the needs of the Board of Directors. The Chairperson of the Nominating, Governance and Sustainability Committee and some or all of the members of the Nominating, Governance and Sustainability Committee and the Board will interview potential candidates that are deemed appropriate. If the Nominating, Governance and Sustainability Committee determines that a potential candidate meets the needs of the Board of Directors, has the qualifications, and meets the standards set forth in the Company's Corporate Governance Principles it will recommend to the Board of Directors the nomination of the candidate.

The Nominating, Governance and Sustainability Committee will consider director candidates recommended by stockholders if properly submitted to the Nominating, Governance and Sustainability Committee. Stockholders wishing to recommend persons for consideration by the Nominating, Governance and Sustainability Committee as nominees for election to the Board of Directors can do so by writing to the Office of the Corporate Secretary at Four Corporate Drive, Lake Zurich, Illinois 60047. Recommendations must include the proposed nominee's name, biographical data and qualifications as well as a written statement from the proposed nominee consenting to be named as a nominee and, if nominated and elected, to serve as a director. The Nominating, Governance and Sustainability Committee will then consider the candidate and the candidate's qualifications. The Nominating, Governance and Sustainability Committee may contact the stockholder making the nomination to discuss the qualifications of the candidate and the reasons for making the nomination and may interview the candidate if the Nominating, Governance and Sustainability Committee deems the candidate to be appropriate.

**Non-Employee Director Stock Ownership Guidelines**

To help align our non-employee directors' interest with those of our stockholders, the Company maintains stock ownership guidelines which require each non-employee director to maintain ownership in shares of the Company's common stock equal to five times his or her annual cash retainer within five years of joining our Board of Directors. Shares counting towards ownership targets include shares beneficially owned through a trust, spouse or dependent child and Restricted Stock Units ("RSUs"). As of December 31, 2025, all directors either met the stock ownership guidelines or were on track to meet the guidelines within the five-year window.

## Director Compensation
Director compensation is set by the Board of Directors upon a recommendation from the Nominating, Governance and Sustainability Committee. The key objective of our non-employee directors' compensation program is to attract and retain highly qualified directors with the necessary skills, experience and character to oversee our management. In addition, our compensation program is designed to align the interests of our Board with the long-term interests of our stockholders by linking a significant portion of director compensation to common stock performance. The compensation program is also designed to recognize the time commitment, expertise and potential liability associated with active Board membership. We compensate our non-employee directors with a combination of cash and equity-based compensation.

The Nominating, Governance and Sustainability Committee reviews non-employee director compensation annually and periodically engages the Compensation and Human Capital Committee's independent consultant to conduct comprehensive reviews, including a review of director compensation of our Peer Group as described in "Executive Compensation—Compensation Discussion and Analysis—Peer Group." The Nominating, Governance and Sustainability Committee uses the data and advice provided by the independent consultant, along with information from benchmarking studies conducted by the National Association of Corporate Directors and others, in formulating its recommendation to the Board regarding non-employee director compensation.

The following table sets forth the compensation paid to members of our Board of Directors in 2025 (other than Mr. Tedford who received no additional compensation for his service on our Board of Directors). Mr. Tedford's compensation is included in the 2025 Summary Compensation Table.

In addition to the annual cash retainer, committee chairpersons receive additional annual cash retainers totaling $25,000 for the Audit Committee, $20,000 for the Compensation and Human Capital Committee, and $15,000 for the Nominating, Governance and Sustainability Committee and Finance and Planning Committee. Our Independent Chairman is paid an additional annual cash retainer of $100,000. Cash retainers are paid quarterly and pro-rated as appropriate.

A non-employee director may elect to defer the cash portion of his or her compensation under our Deferred Compensation Plan for Directors (the "Deferred Plan"). If this option is chosen, the director can have his or her deferral account credited in either or both a phantom fixed income or a phantom stock unit account. The phantom stock unit account would correspond to the value of, and the dividend rights associated with, an equivalent number of shares of the Company's common stock. Upon the conclusion of service as a director, the balance in a phantom stock unit or phantom fixed income account would be paid to the director in a lump-sum cash distribution. Our obligation to redeem a phantom account is unsecured and is subject to the claims of our general creditors. For the year 2025, none of the directors elected to defer cash compensation and none had any balances in a phantom fixed income or phantom stock unit account.

**Equity-Based Compensation for Non-Employee Directors**

Each non-employee director is entitled to receive an annual equity grant either in the form of RSUs deferred under the Deferred Plan or common stock under the 2022 ACCO Brands Corporation Incentive Plan, as amended (including its predecessor or successor plans, the "Incentive Plan") with a fair market value (as defined in the Incentive Plan) of $125,000. Annual equity grants are typically made at the time of our annual stockholders' meeting each year and non-employee directors elected to the Board of Directors other than at an annual meeting receive a pro-rata portion of such amount based on the time between their date of appointment and the date of the next annual stockholders' meeting.

Non-employee directors are required to receive their equity grants in the form of deferred RSUs if they have not yet attained the minimum stock ownership required under the Non-Employee Director Stock Ownership Guidelines. After achieving the minimum stock ownership threshold, directors may elect each year whether to receive an unrestricted stock grant or deferred RSUs under the Deferred Plan.

Under the terms of the Incentive Plan and each individual director's RSU award agreements, each RSU represents the right to receive one share of our common stock. Director RSUs vest in full on the earlier of the first anniversary of the grant date or the date of the next annual stockholders' meeting, provided that the director has been a member of the Board through the vesting date, and subject to accelerated vesting upon certain events. The payment of such RSUs to non-employee directors is deferred under the Deferred Plan. The Deferred Plan provides that such awards are payable within 30 days after the conclusion of service as a director. Directors holding deferred RSUs are credited with additional RSUs based on the amount of any dividend that may be paid by the Company.

**Director Charitable Matching Gift Program**

The Company has established a program under which it will make matching charitable gifts of up to $5,000 annually on behalf of each of its directors. During 2025, two directors participated in this program.

Corporate Governance

The Board of Directors has adopted Corporate Governance Principles to assist it in the exercise of its responsibility to oversee the performance of the Company's management for the benefit of the Company's stockholders and the creation of stockholder value. These principles, along with the charters of the Board of Directors' committees and other key policies and practices of the Board of Directors, provide a framework for the governance of the Company and can be found on our Investor Relations website at https://ir.accobrands.com/governance/governance-documents/default.aspx.

## Director Independence
Our Corporate Governance Principles provide that a majority of the members of the Board of Directors, and each member of the Audit Committee, the Compensation and Human Capital Committee and the Nominating, Governance and Sustainability Committee, must meet certain criteria for independence. Based on NYSE independence requirements, the Corporate Governance Principles set forth certain standards to assist the Board of Directors in determining director independence. Our Board of Directors affirmatively determines director independence on an annual basis after considering all relevant facts and circumstances, namely that the director has no material relationship with the Company, either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company.

Under no circumstances will a director be considered independent if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the director is, or has been within the last three years, an employee of the Company, or an immediate family member is, or has been within the last three years, an executive officer, of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the director is a current partner or employee of a firm that is the Company's internal or external auditor; the director has an immediate family member who is a current partner of such a firm; the director has an immediate family member who is a current employee of such a firm and personally works on the Company's audit; or the director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on the Company's audit within that time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of the Company's present executive officers at the same time serves or served on that company's compensation committee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the Company for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or 2% of such other company's consolidated gross revenue.

ACCO BRANDS \| 2026 PROXY STATEMENT **19**

------

Each currently serving member of the Board of Directors, other than Mr. Tedford, has been affirmatively determined by the Board of Directors to be independent as defined in the Corporate Governance Principles and the NYSE independence requirements.

## Board Leadership Structure
The Board of Directors periodically evaluates the Company's leadership structure and whether it is in the best interests of the Company for the positions of Chairman and CEO to be separated or combined. Our Corporate Governance Principles provide that in the event the Chairman of the Board is also serving as the Company's CEO or is otherwise not independent, one of our independent directors be designated as our Presiding Independent Director. We believe that having an independent Chairman, or a Presiding Independent Director when the Chairman is not independent, provides access to management and an independent voice with significant input into corporate governance matters.

The Board remains satisfied with the current leadership structure and has determined that maintaining the separation of the Chairman and CEO roles continues to be in the best interest of the Company. The Board appointed E. Mark Rajkowski as independent Chairman in 2024 recognizing the value of his seasoned tenure on the Board, his familiarity with the Company's overall business, and his understanding of our corporate governance practices. This structure also allows Mr. Tedford to focus his attention on his responsibilities as CEO.

**Role and Responsibilities of Independent Chairman and Presiding Independent Director**

The Chairman has the authority to call meetings of the Board and presides at such meetings. The Chairman is primarily responsible for shaping Board agendas (in consultation with our CEO, Corporate Secretary, and Presiding Independent Director, if applicable) and communicates with all directors on key issues and concerns outside of Board meetings. He also presides at meetings of all non-employee directors in executive session. Each regularly scheduled Board meeting includes a non-employee director executive session. The independent Chairman, or Presiding Independent Director, as applicable, attends committee meetings, as appropriate, and acts as a conduit for contact between the CEO and the other directors. Together with the chairman of our Compensation and Human Capital Committee, the independent Chairman, or Presiding Independent Director, as applicable, also facilitates the process of evaluating the CEO's performance and determining his compensation. The independent Chairman, or Presiding Independent Director, as applicable, also facilitates and oversees our annual Board self-evaluation process, together with our Nominating, Governance and Sustainability Committee.

## Risk Oversight
Our Board of Directors believes in an effective enterprise risk management program ("ERM"). The objective of our ERM program is to identify in a timely manner the material near-term and emerging risks we face or may face in the future and communicate necessary information about those risks to senior management and, as appropriate, to the Board of Directors or its relevant committees. Additionally, our Board of Directors believes an effective ERM supports the implementation of appropriate and responsive risk management strategies and integrates risk management into our decision-making. Our senior management has primary responsibility for managing enterprise risks and the day-to-day risks associated with our business, including strategic, operational, financial, legal, regulatory, cybersecurity and technology, environmental (including climate-related), social,

governance, geopolitical, reputational, and emerging risks. We have procedures designed to identify, evaluate, monitor, manage and mitigate the major internal and external risks to our business, and to align risk-taking appropriately with our efforts to increase stockholder value.

---

| |
|:---|
| &nbsp;&nbsp;**Board Oversight** |
| &nbsp;&nbsp;Our Board is responsible for the oversight of our enterprise risk management. The Board currently oversees our risk management primarily through our Board committee structure. The Nominating, Governance and Sustainability Committee oversees the ERM procedures established by management, and the Board's standing committees are responsible for the direct oversight of the specific enterprise risks delegated to them, receiving updates from management at least annually on their assigned risks. Management's written presentations regarding these high priority risks are posted to the full Board, and the Board committees regularly provide updates to the Board with respect to the risk areas for which they are responsible. Additionally, management maintains an enterprise risk dashboard which is refreshed quarterly and distributed to the Board.  |

**Cybersecurity**

Our Audit Committee oversees the Company's cybersecurity risks. Ms. Dvorak has a certificate in Cybersecurity Oversight from the National Association of Corporate Directors and Mr. Burton is a technology expert with experience in online fraud and cybersecurity. Both Ms. Dvorak and Mr. Burton are members of our Audit Committee.

Our Senior Vice President and Chief Information Officer and our Vice President, Global Infrastructure, Operations, and Cybersecurity, update the Audit Committee regularly regarding the status of ongoing cybersecurity initiatives and strategies. They also present information to the Audit Committee regarding management's cybersecurity risk and maturity assessments, including changes to our cybersecurity roadmap as a result of these assessments. This briefing is also posted to the full Board, which also receives quarterly updates through the Audit Committee. In accordance with the Company's policies and incident response plans, based on the severity of the incident, the Audit Committee is notified and briefed. The Board and executive management participate in cybersecurity training and conduct tabletop exercises on a periodic basis.

For further information regarding our cybersecurity risk management strategy and governance, see "Item 1C. Cybersecurity" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the Securities and Exchange Commission ("SEC").

**Governance, Social Responsibility and Environmental Sustainability**

The Nominating, Governance and Sustainability Committee oversees our corporate governance policies and practices, including the Code of Conduct and corporate compliance programs and training. Mandatory Code of Conduct training is conducted annually. Areas of focus include anti-corruption and bribery as well as the importance of "speaking up" and the Company's non-retaliation policy. The committee also oversees management's administration of our corporate social responsibility and environmental sustainability programs and reporting. The Nominating, Governance and Sustainability Committee receives management updates on all of these topics with briefings also posted to the full Board.

The Compensation and Human Capital Committee oversees the Company's talent management, development and inclusive culture strategies. Our Global Chief People Officer regularly updates the Compensation and Human Capital Committee on the status of the Company's culture initiatives, talent management and succession planning activities, and reviews these at least once a year with the full Board.

## Artificial Intelligence
The Board recognizes that the use of artificial intelligence ("AI") presents both operational risks and strategic opportunities for the Company. Consistent with its responsibility for oversight of enterprise risk management and internal controls, the Audit Committee oversees risks associated with the Company's use of AI, including data governance, model integrity, information security, third-party vendor risk, regulatory compliance, and the effectiveness of internal controls related to AI-enabled systems. The Company's Senior Vice President and Chief Information Officer, together with other members of management as appropriate, provide regular updates to the Audit Committee regarding AI initiatives, risk assessments, governance frameworks, and control procedures, including developments in applicable laws and regulatory guidance. Based on the nature and severity of identified risks, the Audit Committee is notified and briefed in accordance with the Company's risk escalation protocols. In addition, the full Board receives periodic updates regarding the strategic implications of AI for the enterprise, including AI-enabled innovation, operational efficiencies, competitive positioning, talent implications, and alignment with the Company's long-term growth strategy. This dual oversight framework enables the Board to monitor AI-related risks while guiding management on the responsible and value-enhancing use of AI across the organization.

## Committees
The Board of Directors has established the standing Committees described below, each of which operates pursuant to a written charter that is available on our website at https://ir.accobrands.com/governance/governance-documents/default.aspx. Each committee reviews its charter annually. The independence of these standing committees provides additional oversight and balance to our Board leadership structure, regardless of whether the roles of Chairman and CEO are combined or separated. The CEO does not serve on any of our standing committees.

## Annual Meeting Attendance
We do not have a formal policy requiring members of the Board of Directors to attend stockholders' annual meetings, although all director nominees are currently expected to attend our live audio webcast. All of the director nominees serving on the Board of Directors at the time of the 2025 annual meeting of stockholders attended the 2025 annual meeting, which was also held virtually.

## Board and Committee Self-Evaluation
The Board recognizes that a thorough, constructive self-evaluation process enhances its effectiveness and is an essential element of good corporate governance. Accordingly, the Nominating, Governance and Sustainability Committee, together with our Chairman, or Presiding Independent Director, as applicable, oversees an annual self-evaluation process to ensure that the full Board, each committee, and individual directors conduct a thorough self-assessment of performance and solicit feedback for improvement.

Evaluation topics include board meeting mechanics and content quality; board organization, composition and operation; performance of board members, including the quality and candor of board deliberations; board dynamics and culture; committee performance and director education opportunities. The Nominating, Governance and Sustainability Committee reviews and reassesses the format and effectiveness of the evaluation process each year and makes changes when considered necessary or appropriate. The purpose of the self-evaluation process is to identify ways in which to enhance the effectiveness of the Board's and committees' oversight of the Company's business and financial performance and its corporate governance. Feedback on individual director performance is encouraged as part of the process.

As part of the self-evaluation process, each director completes written questionnaires developed by the Nominating, Governance and Sustainability Committee. The Chairman, or Presiding Independent Director, as applicable, receives a summary of all responses from the written questionnaires and has one-on-one discussions with each director. Each Committee Chair also receives the summary responses for his or her committee and may also have individual discussions with committee members. These results are then presented to the Board and each committee for discussion in executive session.

## Compensation and Human Capital Committee Interlocks and Insider Participation
All members of the Compensation and Human Capital Committee are considered independent under our Corporate Governance Principles. None of the members of the Compensation and Human Capital Committee nor any other member of our Board of Directors served as an executive officer of another entity during 2025 for which any executive officer of the Company served as a director or a member of that entity's compensation committee. None of the members of the Compensation and Human Capital Committee has a relationship with the Company that is required to be disclosed under Item 404 of SEC Regulation S-K.

 **2025 Financial Performance Overview**

*Our Business.* ACCO Brands is a leading global consumer, technology and business branded products company, providing well-known brands and innovative product solutions used in schools, homes and at work. Approximately 75 percent of our 2025 sales came from brands that are in the No. 1 or No.2 position in the product categories in which we compete. Our top 12 brands represented approximately $1.1 billion of our 2025 net sales. Each operating segment designs, markets, sources, manufactures and sells recognized consumer, technology and business branded products used in schools, homes and at work. Product designs are tailored to end-user preferences in each geographic

region, and where possible, leverage common engineering, design and sourcing. Our products are sold primarily in the U.S., Europe, Australia, Canada, Brazil and Mexico.

*Our 2025 Results.* In 2025, net sales were $1.525 billion, a decrease of 8.5 percent. Globally, demand was softer for certain office related products. In addition, sales were impacted by tariff disruptions in the Americas operating segment, primarily in the United States. Gross margin decreased 50 basis points compared to the prior-year period, primarily due to the impact of volume declines and tariff related impacts.

In 2025, we reported an operating income of $92.3 million, compared to operating loss of $37.0 million in the prior year. The increase was primarily due to the prior year non-cash goodwill and intangible asset impairment charge. Adjusted operating income was $153.3 million, compared to $189.7 million in 2024. Adjusted operating income decline reflects lower sales volume and tariff related impacts, which were partially offset by cost savings and lower incentive compensation expense.

Net income was $41.3 million, or $0.44 per share in 2025, compared to a net loss of $101.6 million, or $(1.06) per share in 2024. Current year net income was positively impacted by the settlement of outstanding tax assessments in Brazil, resulting in a benefit of $13.0 million. The prior year loss reflects the items noted above in operating income. Adjusted net income was $78.8 million, compared to $99.2 million in 2024, and adjusted earnings per share were $0.84 per share compared with $1.02 per share in 2024.

For additional information on our business and 2025 financial performance, please see our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC along with our Earnings Release dated March 9, 2026. Adjusted operating income, adjusted earnings per share, and adjusted net income are non-GAAP financial measures. Each non-GAAP financial measure is defined and reconciled to its most directly comparable GAAP financial measure in Appendix B "Supplemental Non-GAAP Financial Measures" of this Proxy Statement.

**Impact of 2025 Company Performance on Executive Compensation**

**2025 Annual Incentive Plan ("AIP")**

We believe the incentive compensation earned in 2025 by our executive officers, including our named executive officers, properly reflects the performance of the Company. For the 2025 AIP award payout, the chart below reflects actual Company financial and strategic measures performance in relation to the full year performance targets established by the Compensation and Human Capital Committee for each performance measure applied to our named executive officers.

(1)Each of the financial performance measures is measured at budgeted currency rates, which are different than actual rates, to remove the impact of year-to-year currency fluctuations that are outside of the control of management.

The financial performance measures were earned by each named executive officer based on actual achievement of adjusted operating income, net sales and working capital efficiency for the Company and/or business segment. Achievement of the strategic measures was based on qualitative judgment informed by quantitative results, as described below.

ACCO BRANDS \| 2026 PROXY STATEMENT **33**

------

Assessment of strategic measures was based on 1) improved revenue performance; delivering on cost savings targets; and managing organizational and structural change, including people, facilities, systems and processes, 2) diversification of new product lines, and 3) progress towards achieving a growth-oriented, inclusive, and highly engaged culture while ensuring development of key successors at all levels of the organization. In February 2026, the Board and Compensation and Human Capital Committee reviewed management's performance relative to these strategic measures. Management successfully managed integration and restructuring projects, leadership transitions in the Americas and International business segments, and actively identified growth and restructure projects for 2026. New product development progressed in 2025, but sales growth did not meet expectations. ACCO Brands has an effective succession planning process and experienced the benefits from the work in 2025. Based on the overall evaluation of the three strategic measures, and as a result of not meeting the expectations of the new product line diversification measure, the Compensation and Human Capital Committee, and the Board for Mr. Tedford, determined that each of the named executive officers earned 50 percent of the strategic measures component of their 2025 AIP award.

**2025 Performance Stock Unit ("PSUs") Results**

The 2023 - 2025 PSUs vested on December 31, 2025 and resulted in a 74.2 percent performance achievement for the cumulative three-year period. For additional information regarding the 2025 AIP and the 2023 - 2025 PSUs, see "Annual Incentive – 2025 Payouts" and "2023 - 2025 PSUs."

**2025 CEO Pay Decisions**

Each year, the Compensation and Human Capital Committee and the Board, with input from the Compensation and Human Capital Committee's independent compensation consultant, Meridian Compensation Partners, LLC ("Meridian"), reviews the CEO's overall compensation package. This review considers, among other things, the CEO's individual performance, the short-term and long-term financial and strategic performance of the Company, and the relative positioning of the CEO's total compensation to the median of the Company's Peer Group.

Mr. Tedford's 2025 base salary and incentive targets as CEO were set on March 11, 2025. In setting Mr. Tedford's 2025 base salary and incentive targets, the Compensation and Human Capital Committee considered the factors noted above and Mr. Tedford's promotion to the CEO position in October 2023.

The Compensation and Human Capital Committee recommended, and the Board of Directors approved, the following actions related to Mr. Tedford's 2025 compensation.

**Summary of Key Executive Compensation Practices**

In overseeing our Company's executive compensation program, the Compensation and Human Capital Committee seeks to provide compensation for our executive officers, including our named executive officers, which is competitive within our industry, with a substantial emphasis on Company performance and stockholder returns. The following list highlights the significant executive compensation practices of the Company which the Compensation and Human Capital Committee believes are effective in aligning the interests of our executive officers with those of our stockholders and are consistent with good corporate governance.

The Peer Group is periodically reviewed and approved by the Compensation and Human Capital Committee, with recommendations from Meridian. |

| ![img213120988_20.jpg](img213120988_20.jpg) | &nbsp;&nbsp;&nbsp;Award Caps | &nbsp;&nbsp;&nbsp;To encourage executive officers to focus equally on short-term and long-term performance goals, our short-term incentive compensation program provides a maximum payout of 185 percent of the target payout and our long-term incentive compensation program provides a maximum payout of 200 percent of the target payout, both of which are aligned with market norms. |

No automatic vesting of equity awards upon a change-in-control. Both a change-in-control and an involuntary termination of employment or termination by executive for "good reason" must occur for equity awards to vest. |

**Executive Compensation Philosophy**

Our executive compensation philosophy is to target each compensation component at approximately the median of similarly situated executives of companies in our Peer Group, with discretion to adjust where individual experience, impact, performance and/or other factors are appropriate. We are committed to providing competitive compensation programs that are designed to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Align with stockholder interests by weighting a substantial portion of total compensation toward at-risk performance-based incentives, which encourage the creation of long-term stockholder value through the achievement of the Company's financial and strategic objectives. In addition, a significant portion of our executive compensation is equity based, which incents our executive officers to increase share price thereby directly benefiting our stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Drive business strategy and pay for performance by linking incentive awards that balance both short-term and long-term financial goals and drive achievement of the Company's business objectives by tying compensation to the accomplishments of those objectives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Attract and retain top talent who can contribute significantly to the achievement of the Company's goals and deliver results critical to our long-term success. We structure compensation programs that reflect the competitive marketplace.

The components of compensation are developed by our Compensation and Human Capital Committee, with advice received from both its independent compensation consultant and our management team and are set annually to ensure alignment with the Company's compensation philosophy.

A substantial portion of executive compensation is at risk. Accordingly, our executive compensation components are weighted toward incentives which we believe encourage the creation of stockholder value through the advancement of our strategy and the achievement of the Company's revenue growth, profitability improvement, cash flow, net income per share, working capital efficiency goals, share price appreciation, and total shareholder return. Though the Compensation and Human Capital Committee has not pre-established any relative weightings among the various compensation components, the Compensation and Human Capital Committee targets the market median in our Peer Group for each compensation component as well as at the overall total compensation of all components combined.

The Compensation and Human Capital Committee reviews the base salary and short-term and long-term incentive compensation mix for executive officers at least annually to ensure alignment with the Company's executive compensation philosophy.

(1)Where exigent circumstances exist, the Compensation and Human Capital Committee may deviate from the compensation core components.

(2)The Compensation and Human Capital Committee determines annually the long-term compensation mix based on a variety of factors, such as participant eligibility, share availability under the Company's Incentive Plan, Peer Group practices, and cost and cash flow impact to the Company. The Compensation and Human Capital Committee has discretion to award cash-based long-term compensation in lieu of stock-based long-term compensation for employees who are not executive officers. Beginning with the March 2023 annual grants, the Compensation and Human Capital Committee determined not to include stock options as a component of the executive officers' long-term compensation mix.

**Role of our Compensation and Human Capital Committee**

Our Compensation and Human Capital Committee is responsible for establishing, overseeing, and monitoring executive compensation and benefit programs for the Company consistent with our pay-for-performance philosophy, as well as the overall human capital strategies that support the Company's strategic business plan. At the direction of the Compensation and Human Capital Committee, management prepares presentations of total compensation, "tally sheets," and other supporting data for the Compensation and Human Capital Committee's use when considering and determining executive compensation. The "tally sheets" provide a succinct summary of all components of each named executive officer's compensation so that the Compensation and Human Capital Committee can analyze each component, the aggregate amount of the components and the impact of Company performance on the value of both short-term and long-term incentive awards.

The Compensation and Human Capital Committee has ultimate authority with respect to all compensation actions, plans, and programs for our executive officers, other than our CEO. The Compensation and Human Capital Committee also annually reviews the total target compensation for the CEO and presents a recommendation to the Board of Directors regarding the CEO's total cash and long-term equity incentive compensation based on this evaluation. The Compensation and

ACCO BRANDS \| 2026 PROXY STATEMENT **39**

Human Capital Committee's recommended annual compensation actions are then discussed with, and approved by, the independent members of our Board of Directors, without Mr. Tedford being present.

Additional information regarding the role of our Compensation and Human Capital Committee is provided under the heading "Corporate Governance—Compensation and Human Capital Committee."

**Role of Our Compensation Consultant and Management**

The Compensation and Human Capital Committee's independent compensation consultant, Meridian, provides competitive compensation data, analysis and guidance to the Compensation and Human Capital Committee, which is used when reviewing and designing our overall executive compensation programs. During 2025, Meridian provided guidance and recommendations to the Compensation and Human Capital Committee on executive officer compensation and related governance matters, including consultation regarding the design of our short-term and long-term incentive awards and non-employee director compensation. During 2025, representatives of Meridian attended all five Compensation and Human Capital Committee meetings, including portions of the executive sessions without management present.

Our executive management makes recommendations regarding executive compensation matters to the Compensation and Human Capital Committee. Management considers the compensation consultant's advice and uses publicly available compensation and benefits survey data and information when making its recommendations to the Compensation and Human Capital Committee. Management may retain other consultants to provide related competitive data and information to assist them in formulating such recommendations. Management's recommendations have historically focused on the Company's broad-based compensation and benefit plans, the structure and performance measures for short-term and long-term incentives, and compensation and benefits related to the Company's executive officers. Members of our management team, including our CEO, may be invited to attend all or portions of the Compensation and Human Capital Committee's meetings. At these meetings, our CEO provides his recommendations regarding compensation and benefits matters pertaining to our other executive officers.

**Independence of Compensation Consultant**

The Compensation and Human Capital Committee received a letter dated January 30, 2025 from Meridian addressing factors relevant to the SEC and NYSE rules regarding independence and potential conflicts of interest. After considering the information and statement provided by Meridian, as well as other factors and information, no conflicts of interest with respect to Meridian's advice were identified by the Compensation and Human Capital Committee, and the Compensation and Human Capital Committee concluded Meridian was an independent consultant.

**Compensation Risk Assessment**

Management and the Compensation and Human Capital Committee conducted a risk assessment of the Company's employee compensation programs and practices, including our executive compensation programs. The Compensation and Human Capital Committee, with assistance from Meridian, reviewed and discussed with management the results of management's evaluation of the Company's compensation programs and practices, and concluded that our employee compensation programs are not designed to incentivize or reward excessive risk-taking and have appropriate risk-mitigating provisions, including caps on incentives and a clawback policy that meets the requirements mandated by the Dodd-Frank Act and goes beyond such requirements by authorizing recoupment of incentive-based compensation from an executive officer who is engaged in willful or intentional

misconduct in connection with the performance of his or her duties. As a result, we believe the risks associated with our compensation programs are within the Company's ability to effectively monitor and manage and are not reasonably likely to have a material adverse effect on the Company. In its discussion, the Compensation and Human Capital Committee considered the attributes of our 2025 compensation program, with key elements summarized below.

| | |
|:---|:---|
| **Key Compensation Elements** | **Key Compensation Elements** |
| ![img213120988_22.jpg](img213120988_22.jpg) | The total compensation pay mix is designed to encourage all employees to act in ACCO Brands' best interests and includes a market-aligned balance of short-term and long-term incentive compensation elements where pay is both fixed (base salary) and performance-based, with sufficient fixed compensation so that employees are not unduly focused on financial performance. |
| ![img213120988_20.jpg](img213120988_20.jpg) | Executive officers' long-term incentive awards are generally paid in equity, which aligns long-term interests of recipients and stockholders, and the mix of award types encourage value creation, retention, and stock price appreciation. |
| ![img213120988_23.jpg](img213120988_23.jpg) | Recipients of long-term incentive awards are subject to our insider trading policy. |
| ![img213120988_24.jpg](img213120988_24.jpg) | Financial performance targets for short-term and long-term incentives are the same for executives and employees alike, include Company-wide performance measures approved by the Committee to ensure they are consistent with Company strategy, and are designed to promote long-term value to stockholders, and incent consistent behavior across the Company.  |
| ![img213120988_25.jpg](img213120988_25.jpg) | Strategic measures are aligned for all executives incenting focused and consistent behavior across the Company. |
| ![img213120988_26.jpg](img213120988_26.jpg) | Multiple and varied performance measures for each of the short-term and long-term incentives encourage executives to focus their efforts on driving balanced performance across the multiple key financial measures. |
| ![img213120988_27.jpg](img213120988_27.jpg) | Change-in-control and severance benefits are aligned with market norms. |
| ![img213120988_28.jpg](img213120988_28.jpg) | Competitive stock ownership guidelines are in place, requiring significant, long-term ownership of Company stock by executive officers. |
| ![img213120988_29.jpg](img213120988_29.jpg) | Short-term and long-term incentive awards are capped at 185 and 200 percent, respectively, of target award opportunity and have threshold requirements. |
| ![img213120988_30.jpg](img213120988_30.jpg) | Anti-hedging/anti-pledging and whistleblower policies are in place and actively communicated to all employees. Our clawback policy complies with the requirements mandated by the Dodd-Frank Act and is designed to deter excessive or inappropriate risk-taking by our executives. The policy requires the recoupment of incentive-based compensation (including equity awards that are subject to time-based or performance-based conditions) affected by accounting restatements as well as in the case of willful or intentional misconduct by the executive in connection with the performance of his or her duties. |

**Peer Group**

In establishing executive compensation, the Compensation and Human Capital Committee, in consultation with Meridian, reviews the compensation of our executive officers in relation to the compensation of executives at a group of comparable companies. We refer to that group of companies as our "Peer Group." The Compensation and Human Capital Committee reviews and approves our Peer Group on a biennial or more frequent basis.

Given our unique mix of consumer, school, technology and office products, it can be difficult to identify companies whose size, business, industry dynamics and other characteristics are largely similar to those of ACCO Brands. Accordingly, the Compensation and Human Capital Committee, in

ACCO BRANDS \| 2026 PROXY STATEMENT **41**

consultation with Meridian, used the following peer-selection criteria to develop a representative Peer Group for the Company.

Companies in the same Global Industry Classification Standard category as current peers were considered and then scored for fit, based on:

**Executive Total Compensation and Compensation Mix**

The Compensation and Human Capital Committee believes that linking pay and performance contributes to the creation of stockholder value. Annually, the Compensation and Human Capital Committee reviews base salary and short-term and long-term incentives relative to our Peer Group companies. For the pay-and-performance link to be effective, experienced individuals who have proven to be strong contributors to the Company's performance should be rewarded with total compensation that falls at approximately the median of total compensation paid to similarly situated executives of the companies in our Peer Group. The Compensation and Human Capital Committee may exercise discretion and consider additional factors such as individual performance, experience level, future potential and specific job assignment of the executive, pay equity, market conditions and the Company's recent performance when determining pay for any of our executive officers.

In considering 2025 total compensation adjustments for the named executive officers other than the CEO, the Compensation and Human Capital Committee used performance assessments by our CEO and the compensation information from our Peer Group and survey data from comparable benchmarks, appropriately aged. In the case of the CEO, the Compensation and Human Capital Committee and the Board of Directors used their performance assessment and Peer Group compensation information. On a total compensation basis, Mr. Tedford's 2025 target total compensation as CEO was below the 50<sup>th</sup> percentile of CEOs in our Peer Group. The target total compensation of each of our named executive officers other than Mr. Tedford, was generally aligned with the median for comparable positions in our Peer Group and/or comparable survey benchmarks following the 2025 compensation actions.

The following graphs show the CEO's and the other named executive officers' 2025 pay mix at total target compensation (i.e., base salary, target annual incentive and target long-term incentive). Each compensation component is described in further detail below. Approximately 85 percent of Mr. Tedford's total target compensation was variable and at risk and approximately 64 percent of the other named executive officers' average total target compensation was variable and at risk. This average reflects the inclusion of Ms. Schneider and Mr. Buchenroth, who did not receive long-term incentive awards in fiscal year 2025 because their planned terminations were known at the time compensation decisions were made and, accordingly, no long-term incentives were granted to them for the year.

Mr. Tedford's CEO target annual incentive opportunity of 120 percent of base salary is at the median target annual incentive opportunity of CEO positions in our Peer Group. The target annual incentive award opportunity percent for our other named executive officers, as a group, was generally aligned with the median target annual incentive opportunity for comparable positions in our Peer Group and/or comparable survey benchmark positions.

The Compensation and Human Capital Committee determined that executive officers would be measured against three financial measures—adjusted operating income (weighted 40%), net sales (weighted 20%) and working capital efficiency (weighted 20%). The Compensation and Human Capital Committee believes that adjusted operating income, net sales, and working capital efficiency focus our executive officers on the strategic transformation of the Company to be more brand-, consumer- and technology-centric. The heavier weighting on adjusted operating income aligns with the Company's strategy to continually improve profitability.

For 2025, the AIP award opportunity for each financial performance measure ranged from a threshold of 25 percent to a maximum of 200 percent of target, with 0 percent payout for below-threshold performance. Each of the financial performance measures described below is measured at budgeted currency rates, which are different than actual rates, to remove the impact of year-to-year currency fluctuations that are outside of the control of management in the near term. Mr. Monko's financial performance measures are tied to his segment's performance. The other named executive officers' financial performance measures are tied to overall company performance.

In 2025, 20 percent of our named executive officers' 2025 target AIP opportunity was determined by performance relative to the strategic measures. Specific strategic measures evaluated as part of the 2025 AIP opportunity included: 1) improved revenue performance; delivering on cost savings targets; and managing organizational and structural changes, including people, facilities, systems and processes, 2) diversification of new product lines, and 3) progress towards achieving a growth-oriented, inclusive, and highly engaged culture while ensuring development of key successors at all levels in the organization. For 2025, the AIP award opportunity for strategic measures ranged from a threshold of 50 percent to a maximum of 125 percent of target, with 0 percent payout for below-threshold performance.

 **Long-Term Incentive Compensation**

Pursuant to the Company's Incentive Plan, the Company may use a variety of long-term incentive awards, such as RSUs, NQSOs, PSUs, Performance Cash and Time-Vested Cash. The Compensation and Human Capital Committee determines annually the long-term compensation mix based on a variety of factors, such as our business strategy, marketplace trends, retention needs, participant eligibility, share availability under the Incentive Plan, Peer Group practices, cost, and cash flow impact to the Company.

**2025 Long-term Incentive Awards**

Mr. Tedford's 2025 Long-term Incentive ("LTI") award was comprised of 67 percent PSUs and 33 percent RSUs. With the exception of Ms. Schneider and Mr. Buchenroth who did not receive LTI awards in 2025, the 2025 LTI awards for the other named executive officers were comprised of 60 percent PSUs and 40 percent RSUs. No stock options were granted to executive officers in 2025.

In establishing the 2025 LTI grant values, the Compensation and Human Capital Committee reviewed the LTI compensation data for the companies in our Peer Group. Mr. Tedford's 2025 LTI award at target was below 50th percentile LTI value of CEO positions in our Peer Group. The 2025 LTI grant values for our other named executive officers who received awards were near the 50th percentile of target LTI values for comparable positions in our Peer Group and/or comparable survey benchmark positions. Ms. Schneider and Mr. Buchenroth did not receive LTI awards in fiscal year 2025 because their planned terminations were known at the time compensation decisions were made and, accordingly, no long-term incentives were granted to them for the year.

The following is a description of the terms of the Restricted Stock Units (RSUs) and Performance Stock Units (PSUs) that were granted in 2025.

TSR for the Peer Group and the Company for the period beginning on January 1, 2025 and ending on December 31, 2027 was calculated by subtracting the beginning stock price from the ending stock price (in each case, including reinvested dividends) and dividing by the beginning stock price (including reinvested dividends). For purposes of calculating the TSR Modifier, the beginning and ending stock price equal the average of the last 30 trading days stock price ending on the calculation date.

**2023 - 2025 PSUs**

For the 2023 - 2025 PSU award payout, the chart below reflects actual Company financial measure performance in relation to the three, one-year performance targets established by the Compensation and Human Capital Committee for each performance measure and TSR performance modifier.

The 2023 - 2025 PSUs vested on December 31, 2025. The 2023 - 2025 PSU actual performance on the financial measures (adjusted earnings per share, adjusted free cash flow, and gross profit margin, as defined in the plan documents) resulted in 74.2 percent achievement. ACCO Brands ranked above the 25th percentile relative to the Peer Group over the three-year cumulative period, and thus no modifier was applied to financial performance, resulting in 74.2 percent of target performance achievement for the three-year period.

As a result, each of Messrs. Tedford, Monko, Buchenroth and McCormack, earned 219,916, 104,599, 72,934, and 35,366 shares (including accrued dividend equivalents), respectively, and Mss. O'Connor, Schneider and Jones earned 104,599, 65,706 and 42,339 shares (including accrued dividend equivalents), respectively. The share amounts earned by Mr. Buchenroth and Ms. Schneider were prorated based on their respective periods of service during the three-year performance period.

**Timing of Equity Grants**

Under the Company's equity award grant policy, each year's annual equity-based compensation awards (including options, if any) are granted to executive officers and other eligible employees during the first quarter of each year after the release of full-year earnings, unless circumstances arise that warrant establishing different dates, including share conservation strategies. Off-cycle (non-annual) awards may be made if our CEO and the Compensation and Human Capital Committee deem it necessary for newly promoted employees, strategic new hires, or in other special or unique circumstances. In such cases, the effective date for an off-cycle award is the first trading day of the month following a newly hired/promoted eligible employee's effective date of hire or promotion, as the case may be.

**50** ACCO BRANDS \| 2026 PROXY STATEMENT

------

The Company does not schedule its equity grants in anticipation of the release of material, non-public information ("MNPI"), nor does the Company time the release of MNPI based on equity grant dates, in each case in a manner that would provide award recipients an opportunity benefit from such MNPI. In the event MNPI becomes known to the Compensation and Human Capital Committee prior to granting an equity award, the Committee will take the existence of such information into consideration and use its business judgment to determine whether to delay the grant of equity to avoid any appearance of impropriety. In 2025, no stock options or similar option-like awards were granted to our named executive officers, including during any period beginning four business days before the filing or furnishing of an annual, periodic or current report disclosing MNPI and ending one business day after the filing or furnishing of such report with the SEC.

**Retirement Benefits**

In line with our overall compensation philosophy, the Company has historically aimed to provide competitive retirement benefits. In the United States, this has been done by providing retirement benefits through a combination of both tax-qualified and non-qualified defined benefit plans and tax-qualified and non-qualified defined contribution plans.

**Defined Contribution - 401(k) - United States**

All of the Company's named executive officers (other than Mr. Monko) were participants in the Company's U.S. tax-qualified 401(k) retirement savings plan (the "ACCO Brands 401(k) Plan") during 2025. In 2025, the ACCO Brands 401(k) Plan matched employee contributions at 100 percent of the first six percent of eligible plan compensation. These matching contributions apply to all participating employees, including our named executive officers (other than Mr. Monko).

**Defined Contribution - Non-Qualified Deferred Compensation Plan - United States**

Non-qualified plans provide a supplemental benefit to recognize and account for certain employee earnings that exceed the IRS maximum for a qualified plan. Contributions under the non-qualified deferred compensation plan are not eligible for Company matching contributions. All other plan benefits mirror, and are determined, on the same basis as those provided under our qualified defined contribution plan. The Company operates all applicable plans and agreements in compliance with Section 409A of the Code. A more detailed discussion of the Company's non-qualified deferred compensation arrangements is provided under the heading "Executive Compensation—Non-Qualified Deferred Compensation."

**Defined Benefit - Pension - United States**

The ACCO Brands Corporation Pension Plan for U.S. salaried and hourly employees (the "ACCO U.S. Pension") was frozen in the first quarter of 2009. As a result, none of the executive officers who participate in the ACCO U.S. Pension have accrued any additional benefits under this plan since that time. More information is provided under the heading "Executive Compensation Tables—2025 Summary Compensation Table" and "Executive Compensation Tables—Pension Benefits".

**Retirement Plans - Poland**

Mr. Monko is entitled to a pension benefit under the Company's Polish broad-based defined benefit pension plan upon retirement on or after age 65, and he participates in Polish Private Employee Capital Plan, known as a PPK, which is a private long-term saving system established by the Polish government. The amount of benefits provided to Mr. Monko in the form of PPK employer contributions is included in the "All Other Compensation" column of the 2025 Summary Compensation Table and

related footnotes. More information is provided under the heading "Executive Compensation Tables—2025 Summary Compensation Table" and "Executive Compensation Tables—Pension Benefits."

**Health and Other Benefits**

The employee medical and welfare benefits provided to executive officers are offered through broad-based plans available to all employees in the given geography.

**Perquisites**

The Compensation and Human Capital Committee approved a limited number of low-cost perquisites for executive officers, which are either legacy in nature, or the perquisite is common practice in a given geography. The costs to the Company and a description of personal benefits provided to our named executive officers are included in the "All Other Compensation" column of the 2025 Summary Compensation Table and related footnotes.

**Executive Severance Plan**

The Company does not provide individual employment contracts for executive officers, unless having an employment contract is a common practice in a given geography. All of the Company's executive officers, including the currently serving named executive officers, participate in the Company's Executive Severance Plan (the "ESP"), which is administered by the Compensation and Human Capital Committee. The ESP is intended to help the Company attract and retain executives in a talent marketplace where such employment protections are commonly offered, including among our Peer Group companies. Though Mr. Monko has an employment contract, which is governed by Polish law, his severance benefits are established by the ESP.

Further details regarding severance benefits provided under the ESP is provided under the heading "Executive Compensation Tables—Potential Payments Upon Termination or Change-in-Control" and the related tables.

**Executive Stock Ownership Guidelines**

To further align executive officers' interests with those of our stockholders, the Company maintains the following stock ownership guidelines, which apply to all executive officers. Executives must attain the level of stock ownership appropriate to their position as a multiple of base salary or a number of shares, whichever is lower.

---

| | | |
|:---|:---|:---|
| **Executive Level** | **Number of Shares** | **Multiple of Base Salary** |
| Chief Executive Officer | 500,000 | 6.0X |
| Chief Financial Officer and Segment Presidents | 125,000 | 3.0X |
| Other Executives | 60,000 | 2.0X |

---

Executive officers are generally expected to achieve their respective ownership goals within five years of becoming an officer. If an executive is promoted to a higher level requiring greater stock ownership, he or she has five years from the date of such promotion to achieve the new level. All executive officers either attained or are on track to attain the requirements of the guidelines within the required time frame.

Shares that count towards ownership targets include shares owned directly, in joint accounts or by a spouse or dependent child(ren); shares held through Company retirement plans; shares beneficially

**52** ACCO BRANDS \| 2026 PROXY STATEMENT

------

owned through a trust or similar estate planning device; vested and unvested restricted stock units (RSUs), including dividend equivalents; and earned performance stock units (PSUs), including dividend equivalents. Attainment is achieved at either the lower of a multiple of salary or a number of shares, which the Compensation and Human Capital Committee believes reduces the impact of stock price volatility.

Following the vesting of PSUs or RSUs, or the exercise of stock options, executive officers who have not yet met their applicable stock ownership goals (in number of shares or value) are expected to retain at least 50 percent of the net value of shares of stock received (e.g., the net value after deduction of the exercise price and all applicable tax and other required withholding). Subject to the Company's insider-trading policy, an executive officer may reduce his or her share ownership so long as his or her ownership is maintained at or above the required ownership levels.

The Compensation and Human Capital Committee has the discretion to remedy any deficiency if ownership goals are not met on a timely basis. Remedies may include providing a portion of annual incentive awards in Company stock or similar actions. The Compensation and Human Capital Committee may also consider other factors, including general equity market conditions and the Company's then-current stock price when determining the need for any remedies.

**Prohibitions on Hedging, Pledging and Similar Transactions**

Hedging and similar monetization transactions by directors and employees, including executive officers, which may offset or protect against decreases in the market price of our Company stock, can lead to a misalignment between the objectives of these individuals and the objectives of our stockholders. Similarly, stock pledges by directors and executive officers could detrimentally impact our stockholders if they are used as part of a hedging strategy or in the event of a forced sale of our stock, such as to meet a margin call. Accordingly, under our insider trading policy:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•directors and employees, including our executive officers, are prohibited from engaging in any hedging transactions with respect to the Company stock they may own, including through prepaid variable forward contracts, equity swaps, collars and exchange funds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•directors and executive officers are prohibited from trading in puts, calls, exchange-traded options or similar securities involving our stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•directors and employees, including executive officers, are prohibited from engaging in short sales of our stock; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•directors and executive officers are prohibited from holding our securities in margin accounts or otherwise pledging our securities as collateral for a loan, and all other employees must receive pre-clearance from the Company in order to do so.

Our insider trading policy does not provide for exceptions or waivers to these prohibitions.

**Recoupment or Forfeiture of Incentive Payments Policy**

The Company has a policy to "clawback" incentive-based compensation paid or payable to executive officers in the event of a financial restatement or under the circumstance of willful and intentional misconduct on the part of an executive in connection with the performance of his or her duties. The policy defines "incentive-based compensation" to include all forms of compensation that is granted, earned or vested (i) based wholly or in part upon the attainment of a financial accounting measure, including annual bonuses and long-term incentive plans, and/or (ii) based wholly or in part upon the occurrence of specified events or the achievement of specified individual or corporate performance

ACCO BRANDS \| 2026 PROXY STATEMENT **53**

------

goals, in each case whether paid in the form of cash or equity. Other forms of compensation, such as time-based equity awards the vesting of which is not dependent on the achievement of performance measures, may also be the subject of clawback in the event of willful or intentional misconduct. Under the policy, executive officers who receive any such cash or equity incentive compensation payments may be required to forfeit or reimburse the Company for those payments, as the case may be, in the event that either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the amount was based upon the achievement of financial results that were subsequently the subject of an accounting restatement required by the federal securities laws, and a lower amount would have been paid to the executive officer based on the restated amount, regardless of whether the executive officer was responsible for the restatement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the Board of Directors determines that the executive officer engaged in willful or intentional misconduct with respect to the performance of his or her duties, including but not limited to "cause" as defined in the ESP, misappropriation or misuse of corporate assets, or opportunities, or confidential information, breach of fiduciary duty owed to the Company, or violation of restrictive covenants.

The policy complies with the requirements mandated by the Dodd-Frank Act in requiring the recoupment of incentive-based compensation affected by accounting restatements. However, the policy goes beyond the minimum requirements of the Dodd-Frank Act by continuing in effect the portion of the policy, which was adopted prior to the enactment of the Dodd-Frank Act, that allows the Company to recover incentive-based compensation, including equity awards not subject to performance measures, paid to executive officers who engage in willful and intentional misconduct.

In circumstances described above, the Company may seek to recover from the executive officer, either by repayment of cash or equity incentives already paid or cancellation or forfeiture of outstanding cash or equity incentive compensation awards not yet earned, or by offset against other amounts owed to the executive officer, either the amount by which his or her cash or equity incentive payments exceeded the lower payment that would have been made based on the restated financial results, or, in the case of willful or intentional misconduct, an amount equal to the value of any cash or equity incentive payments received during the three-year period prior to the executive's termination of employment (or, if longer, the period during which the misconduct existed), or after the termination. Except in the case of a recovery mandated by the Dodd-Frank Act, the Board may waive or reduce an executive officer's repayment obligation based upon hardship, the executive officer's degree of culpability or responsibility, or such other factors as the Board deems appropriate.

The plan provides for a one-time lump sum payment in an amount equal to three times the employee's monthly average base salary in effect over the last three months of his employment, subject to taxation. There are no service requirements or early retirement provisions for this benefit. Mr. Monko must be working for the Company at the time of his retirement in order to receive this benefit. The aggregate increase in actuarial present value is included in the "Change in Pension Value" column of the 2025 Summary Compensation Table.

Defined Contribution - In November 2019, Mr. Monko became a participant in the Polish Private Employee Capital Plan, known as a PPK, which is a private long-term saving system established by the Polish government. For employees aged 55-70, participation in the program is voluntary, however matching retirement contributions by the employer are mandatory. Mr. Monko, whose age is above 55 voluntarily contributes to the PPK and, in turn, receives an obligatory employer contribution as well. The amount of benefits provided to Mr. Monko in the form of PPK employer contributions is included in the "All Other Compensation" column of the 2025 Summary Compensation Table and related footnotes.

**ACCO U.S. Non-Qualified Deferred Compensation**

The ACCO U.S. Non-Qualified Deferred Compensation Plan is an unfunded plan maintained by the company for the purpose of providing deferred compensation for a select group of management or highly compensated employees within the meaning of Sections 201(2), 301(a)(3), and 401(a)(1) of the Employee Retirement Income Security Act of 1974, as amended, or an "excess benefit plan" within the meaning of Section 3(36) of the Employee Retirement Income Security Act of 1974, as amended, or both.

This is a voluntary plan and participants may elect to defer between 1 and 50 percent of annual base salary and between 1 and 90 percent of their Annual Incentive Plan payout. Deferral elections must be made in the year before compensation is earned and reduce the eligible compensation available for deferral in the ACCO Brands 401(k) Plan. Deferral elections are irrevocable and distribution dates of a prior separation or in-service election can be changed one time only. Participants are immediately vested in their contributions made to the plan, as well as any earnings on these contributions. Investment options available through the plan are nearly identical to those offered under the ACCO Brands 401(k) Plan. Participant contributions and earnings within the plan are subject to the claims of ACCO Brands creditors.

**Potential Payments Upon Termination or Change-In-Control**

The Company does not have written employment agreements with its executive officers, including the named executive officers, unless it is common practice to provide an individual employment contract, such as in select international markets where we have executive officers. Only Mr. Monko, whose employment is based in Poland, has an employment contract. All of our executive officers, including all our currently serving named executive officers, were covered by the Company's ESP on December 31, 2025 and continue to be so covered as of the date of this Proxy Statement. Ms. Schneider retired on September 30, 2025, and Mr. Buchenroth terminated employment on August 1, 2025.

The Company's ESP in effect as of December 31, 2025 provides the named executive officers with the following payments and benefits upon (i) an involuntary termination without "cause," (ii) voluntary termination for "good reason" or (iii) involuntary termination without "cause" within 6 months before or 24 months after a change-in-control as defined in the ESP:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Involuntary Termination: 24 months of base salary and two years of target bonus for the year of separation for Mr. Tedford; 21 months of base salary and one year of target bonus for the year of separation for Mr. Monko and Ms. O'Connor; 18 months of base salary and one year of target bonus for the year of separation for Mr. McCormack, Ms. Jones, and all other executive officers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Change-in-Control Termination: 2.99 times base salary plus 2.99 times target bonus for the year of separation for Mr. Tedford; 2.25 times base salary plus 2.25 times target bonus for the year of separation for Mr. Monko and Ms. O'Connor; 2 times base salary plus 2 times target bonus for the year of separation for Mr. McCormack, Ms. Jones, and all other executive officers. The executive would also receive a pro-rata annual bonus for the year of the executive's termination up through and including the termination effective date calculated based upon actual performance as approved by the Compensation and Human Capital Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Outplacement services in a value commensurate with the level of the position.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Any amounts payable under the ESP are reduced by amounts payable to a named executive officer under any other severance plan applicable to the named executive officer or any other agreement that has been entered into between the Company and the named executive officer.

In accordance with Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), if the severance calculation is subject to an excise tax, the Company will calculate two severance payment alternatives and determine which alternative results in the highest net amount of severance payment for each executive officer, commonly referred to as the best-net approach. Either the aggregate of all severance payments for an executive officer will be paid as calculated and subject to regular payroll income tax and excise tax, or the aggregate of all severance payments for an executive officer shall be reduced prior to payment to a gross amount that results in the largest net amount for that executive officer so as to remain subject to regular payroll income tax but not subject to excise tax. Mr. Monko is not subject to Section 4999 of the Code.

Medical and other welfare benefits continue for the named executive officer's severance period on the same cost-sharing basis as if employment had not terminated. No severance or change-in-control payments would be made until the named executive officer executes a release waiving any and all claims the executive may have against the Company. No benefits would be provided to a named executive officer if a termination was for "cause" or voluntary (other than in the case of a retirement) except where required by law or at the discretion of the Board of Directors. In addition, certain equity grants awarded to the named executive officers may accelerate upon death, disability, retirement, termination without cause and in the event of a change-in-control as defined in the Incentive Plan.

ACCO BRANDS \| 2026 PROXY STATEMENT **63**

------

The table below reflects the estimated payments and other benefit amounts that would have been received by each named executive officer or his or her estate under the following events as if each such event occurred as of December 31, 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a change-in-control without termination of employment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•termination of employment by the executive officer due to retirement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•termination of employment by the Company without cause;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•following (or in certain circumstances preceding) a change-in-control, a termination of employment by the Company without "cause" or by the executive officer for "good reason"; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•termination of employment as a result of death or disability.

In preparing the table, it is assumed that each of the named executive officers has no earned but unpaid salary or accrued and unused vacation benefits at the time of his or her termination and that the values reflect compensation in addition to what he or she would have earned had the described event not occurred. Messrs. Tedford, Monko and McCormack and Ms. Jones are retirement eligible.

## CEO Pay Ratio
Pursuant to the rules adopted by the SEC, we are required to disclose the ratio of the median of the annual total compensation of all our employees, other than our CEO, to the annual total compensation of our CEO, which we refer to as the "Pay Ratio." The Pay Ratio is intended to be a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. The table below reflects the Pay Ratio with respect to 2025 compensation:

---

| | |
|:---|:---|
| CEO 2025 Annual Total Compensation | $4488934 |
| Median Employee 2025 Annual Total Compensation | $40291 |
| Pay Ratio of CEO to Median Employee Compensation | 111 : 1 |

---

There have been no changes in our employee population or employee compensation arrangements that we believe would significantly impact the Pay Ratio disclosure. Accordingly, we are using the same median employee for 2025 as we used for 2024. In a manner consistent with Item 402(u) of Regulation S-K, this is the second year using the median employee identified in 2024.

To identify the median employee in 2024, we examined the total cash compensation paid between October 1, 2023 and September 30, 2024, including base salaries, overtime payments, allowances, incentives and commissions paid, to all individuals, excluding our CEO, who were employed by us as of October 1, 2024, as reflected in our payroll records. In accordance with Item 402(u) and instructions thereto, we included all full-time, part-time, temporary and seasonal employees. We selected total cash compensation for all employees as a consistently applied compensation measure because we do not widely distribute long-term incentive awards to

**66** ACCO BRANDS \| 2026 PROXY STATEMENT

------

employees and because we believe that this measure reasonably reflects the total annual compensation of our employees. For purposes of calculating the total cash compensation of our non-U.S. employees, we converted local currencies to U.S. dollars based on our fiscal year 2024 operating plan exchange rates.

We calculated the 2025 annual total compensation for the representative median employee using the same methodology we use for our named executive officers in the 2025 Summary Compensation Table in this Proxy Statement. With respect to the annual total compensation of our CEO, we used the amount reported in the "Total" column of our 2025 Summary Compensation Table in this Proxy Statement.

Our Pay Ratio has been calculated using selected assumptions, estimates and adjustments as permitted under Item 402(u) of Regulation S-K, and is a reasonable estimate calculated in a manner consistent with the Regulation. Other companies may use different methodologies, assumptions, estimates and adjustments, and therefore a comparison of our Pay Ratio to that of other companies will be limited in value.

## Pay Versus Performance
In accordance with rules adopted by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we provide the following disclosures regarding the relationship between the executive compensation for our principal executive officers ("PEOs") and the other named executive officers (the "Non-PEO NEOs") and the Company's performance for the fiscal years listed below. The Compensation and Human Capital Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown.

(2)The amounts shown for Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the Company's NEOs.

(3)Compensation Actually Paid reflects total compensation as disclosed in the Summary Compensation Table as adjusted to exclude and include certain amounts for the PEOs and the Non-PEO NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718. Amounts in the Exclusion of Stock Awards column are the totals from the Stock Awards column set forth in the Summary Compensation Table. Amounts in the Exclusion of Change in Pension Value column reflect the amounts attributable to the Change in Pension Value reported in the Summary Compensation Table. Amounts in the Inclusion of Pension Service Cost are based on the service cost for services rendered during the listed year.

(4)The Peer Group TSR utilizes the S&P Office Services and Supplies (SuperCap1500) Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report on Form 10-K for the year ended December 31, 2025. The comparison assumes $100 was invested in the Company and in the S&P Office Services and Supplies (SuperCap 500) Index for the period starting December 31, 2020 through the end of the listed year. Historical stock performance is not necessarily indicative of future stock performance.

(5)We determined adjusted operating income to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to PEO 2 and the Non-PEO NEOs in 2025. Adjusted operating income is a non-GAAP financial measure. Adjusted operating income is defined and reconciled to its most directly comparable GAAP financial measure in Appendix B "Supplemental Non-GAAP Financial Measures" of this Proxy Statement.

Each of our director nominees possesses the judgment and business and educational background required, has a proven track record of success in his or her field as well as a reputation for integrity, honesty and adherence to high ethical standards. We believe each director has business acumen, ability to exercise sound judgment and a commitment of service to our Company, its stockholders and the Board of Directors.

Each of the director nominees has consented to serve a one-year term if elected. If any director nominee should become unavailable to serve as a director, the Board of Directors may designate a substitute nominee. In that case, the persons named as proxies will vote for the substitute nominee designated by the Board of Directors. Additionally, in accordance with the Company's Corporate Governance Principles, each director nominee has submitted a contingent, irrevocable resignation that the Board may accept in the event that the votes cast for the director nominee's election do not exceed the votes cast against the director nominee's election (with abstentions and broker non-votes not counted as a vote cast either for or against the director nominee's election). In that event, the Nominating, Governance and Sustainability Committee (or a special committee consisting solely of independent directors not subject to a failed vote) would make a recommendation to the Board about whether to accept or reject the resignation, or whether to take other action. The Board would then act on this recommendation within 90 days of the date that the election results were certified, and the Company would promptly publicly disclose the Board's decision.

| **☑ The Board of Directors recommends you vote FOR Proposal 2.** | **☑ The Board of Directors recommends you vote FOR Proposal 2.** |

---

The Audit Committee has appointed KPMG LLP ("KPMG") as our independent registered public accounting firm for the fiscal year ending December 31, 2026. During 2025, KPMG served as the Company's independent registered public accounting firm and also provided certain other services to the Company. The Audit Committee and the Board of Directors recommend that you ratify this appointment. In line with this recommendation, the Board of Directors intends to introduce the following resolution at the Annual Meeting:

**"RESOLVED, that the appointment of KPMG LLP as the independent registered public accounting firm for the Company for the year 2026 is ratified."**

The Audit Committee is responsible for the selection, retention and oversight of the Company's independent registered public accounting firm. If stockholders do not ratify the appointment of KPMG as the Company's independent registered accounting firm for 2026, the Audit Committee will reconsider its selection but may, nevertheless, continue to retain KPMG. Even if the selection is ratified, the Audit Committee has the discretion to appoint a different registered public accounting firm at any time during the year if the Audit Committee determines that such change would be appropriate.

A member of KPMG is expected to be in attendance during the Annual Meeting to make a statement if he or she desires and will respond to appropriate questions that may be asked by stockholders.

**Audit and Non-Audit Fees**

Our independent registered public accounting firm for the 2024 and 2025 fiscal years was KPMG. The following table summarizes the fees paid or payable by the Company to KPMG for services rendered during 2024 and 2025, respectively:

---

| | | |
|:---|:---|:---|
| **Fees** | **2024** | **2025** |
| Audit fees<sup>(1)</sup> | $3447311 | $3302420 |
| Audit-related fees<sup>(2)</sup> | $8218 | $12800 |
| Tax fees<sup>(3)</sup> | $1525 | $1900 |
| All other fees<sup>(4)</sup> | 11017 | $10800 |
| Total | $3468071 | $3327920 |

---

(1)Audit fees include fees for the audit of our annual financial statements, the audit of the effectiveness of the Company's internal control over financial reporting, the review of the financial information included in our Form 10-Q quarterly reports filed with the SEC, and services performed in connection with statutory audits and regulatory filings or engagements. The decrease in audit fees was primarily due to lower base fee and non-recurring fees.

ACCO BRANDS \| 2026 PROXY STATEMENT **73**

------

(2)Audit-related fees include professional services related to the performance of the audit and are primarily agreed upon procedures and compliance audits required under various local international regulations.

(3)Tax fees consist principally of professional services rendered for international tax compliance work.

(4)All other fees relate to professional services rendered for the compilation of statutory financial statements for specific international legal entities.

 **Approval of Audit and Non-Audit Services**

All audit and non-audit services provided to the Company by KPMG are approved in advance by the Audit Committee or by the Chairman of the Audit Committee, who has been delegated authority to approve such services on behalf of the Audit Committee. The Audit Committee has adopted the following policies and procedures for the pre-approval of all audit and permissible non-audit services provided by our independent registered public accounting firm. The Audit Committee annually reviews the audit and non-audit services to be performed by the independent registered public accounting firm during the upcoming year. The Audit Committee considers, among other things, whether the provision of specific non-audit services is permissible under existing law and whether it is consistent with maintaining the registered public accounting firm's independence. The Audit Committee then approves the audit services and any permissible non-audit services it deems appropriate for the upcoming year. The Audit Committee's pre-approval of non-audit services is specific as to the services to be provided and includes preset spending limits. The provision of any additional non-audit services during the year, or the provision of services in excess of preset spending limits, must be pre-approved by either the Audit Committee or by the Chairman of the Audit Committee, who has been delegated authority to pre-approve such services on behalf of the Audit Committee. Any pre-approvals granted by the Chairman of the Audit Committee must be reported to the full Audit Committee at its next regularly scheduled meeting. All of the fees described above for services provided to the Company under audit fees, audit-related fees, tax fees and all other fees were pre-approved by the Audit Committee in accordance with the Company's pre-approval policies and procedures.

**Transactions with Related Persons**

The Audit Committee is responsible for review, approval, or ratification of "related-party transactions" as defined under applicable SEC rules that involve the Company or its subsidiaries. We have adopted a formal written policy that requires the Audit Committee to review and, if appropriate, to approve or ratify any transaction exceeding $120,000 in value in which the Company is, or will be, a participant, and in which any of the Company's directors or executive officers or any of their immediate family members had, has or will have a direct or indirect material interest. After its review, the Audit Committee will only approve or ratify those transactions that are in, or are not inconsistent with, the best interests of the Company and its stockholders, as the Audit Committee determines in good faith. During fiscal 2025, there were no transactions, and there currently are no proposed transactions, meeting the criteria outlined above.

**Report of the Audit Committee** 

The Audit Committee is composed of directors that are "independent" as defined under the NYSE corporate governance listing standards and Rule 10A-3 of the Exchange Act. The Audit Committee oversees the Company's financial reporting process on behalf of the Board of Directors. Management is responsible for the Company's financial statements and the financial reporting process, including implementing and maintaining effective internal control over financial reporting and for the assessment of, and reporting on, the effectiveness of internal control over financial reporting. The Company's independent registered public accounting firm for 2025, KPMG, is responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States and for expressing an opinion on the effectiveness of the Company's internal control over financial reporting. In fulfilling its oversight responsibilities, the Audit Committee has reviewed and discussed with management and KPMG the Company's audited financial statements for the year ended December 31, 2025, and the reports on the effectiveness of internal control over financial reporting as of December 31, 2025, contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, including a discussion of the reasonableness of significant judgments and clarity of disclosures in the financial statements. The Audit Committee also reviewed and discussed with management the disclosures made in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

The Audit Committee has reviewed and discussed with KPMG the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC. In addition, the Audit Committee has discussed with KPMG the firm's independence from the Company, including the matters in the written disclosures and letter provided to the Audit Committee by KPMG regarding the firm's communications with the Audit Committee concerning independence as required by the PCAOB and has considered the compatibility of non-audit services with the auditing firm's independence.

The Audit Committee discussed with KPMG the overall scope and plans for its integrated audit. The Audit Committee meets with KPMG, with and without management present, to discuss the results of the firm's examinations, its evaluations of the Company's internal controls and the overall quality of the Company's financial reporting. Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the Board of Directors has approved, that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the SEC.

| **☑ The Board of Directors recommends you vote FOR Proposal 3.** | **☑ The Board of Directors recommends you vote FOR Proposal 3.** |

---

We are providing our stockholders with an opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our named executive officers, as required under Section 14A of the Exchange Act. The proposal, commonly known as a "Say-on-Pay" proposal, is designed to give our stockholders the opportunity to endorse or not endorse our executive compensation program through the following resolution:

 **"RESOLVED, that the stockholders approve, on an advisory basis, the compensation of the Company's named executive officers as disclosed in the Company's Proxy Statement for the 2026 Annual Meeting of Stockholders, including in the Compensation Discussion and Analysis, the executive compensation tables and other related disclosures contained therein."**

As discussed in the Compensation Discussion and Analysis, we have designed our executive compensation program to attract, retain and motivate highly skilled executive officers, link pay to performance, and build sustainable value for our stockholders. When you cast your vote, we urge you to consider the description of our executive compensation program contained in this Proxy Statement, including under the heading "Compensation Discussion and Analysis" and the accompanying executive compensation tables and related footnotes.

Because your vote is advisory, it will not be binding upon our Board of Directors, it will not overrule any decision by the Board of Directors, and it will not create or imply any additional fiduciary duties on the Board of Directors or any member thereof. However, the Compensation and Human Capital Committee and our Board of Directors will take into account the outcome of the vote when considering future executive compensation arrangements.

In May 2023, stockholders voted to hold a "Say-on-Pay" vote annually. The next vote on the frequency of the "Say-on-Pay" vote will be held at the 2029 Annual Meeting.

| **☑ The Board of Directors recommends you vote FOR Proposal 4.** | **☑ The Board of Directors recommends you vote FOR Proposal 4.** |

---

At the Annual Meeting, stockholders will vote on a proposal to approve an amendment to the 2022 ACCO Brands Corporation Incentive Plan, as amended (the "Plan"). On March 11, 2026, the Company's Board of Directors approved the amendment to the Plan, subject to stockholder approval at the Annual Meeting, based upon a recommendation of the Compensation and Human Capital Committee and management. A copy of the form of the proposed amendment is attached as Appendix A to this proxy statement. The purpose of the amendment is to:

&nbsp;&nbsp;&nbsp;&nbsp;•increase the number of shares available for future grant under the Plan by 4,100,000 shares; and

&nbsp;&nbsp;&nbsp;&nbsp;•eliminate the fungible share counting ration for new awards.

These changes, together with the shares currently available for future grants, are intended to cover grants for approximately one year based on current grant practices. The actual rate at which we use shares under the Plan may be more or less than our anticipated future usage and will depend upon various factors, such as our future stock price, plan participation levels, hiring and promotion activity, award mix and vehicles, competitive market practices, acquisitions and divestitures, and rates of forfeiture.

Due to limited remaining shares, the Company will defer the Performance Share Unit portion of the upcoming 2026 long-term incentive grants for Executive Officers until stockholders approve the share increase. If the amendment is not approved, these Executives will not receive their PSU awards.

## Why Stockholders Should Approve the Proposed Amendment
The Board believes that the proposed amendment to the Plan is in the best interests of the Company and its stockholders. The Plan is designed to align employee and stockholder interests by enabling the Company to continue granting stock-based compensation, including performance-based awards without causing unreasonable dilution. It includes features that protect stockholder interests as described below.

&nbsp;&nbsp;&nbsp;&nbsp;•<u>Critical to Attract and Retain Talent</u>: Equity-based compensation remains essential to attracting, motivating and retaining the talent needed to drive the Company's long-term success. The Plan also provides the flexibility to grant awards to non-employee directors. For these reasons, the Board views the Plan as a key component of the Company's compensation program and believes the increase available shares for the grant of awards under the Plan will enable it to continue to fulfill this function.

&nbsp;&nbsp;&nbsp;&nbsp;•<u>Responsible Share Usage</u>: The Compensation and Human Capital Committee and the Board of Directors monitors share usage to manage the dilutive impact of awards granted under the Plan.

ACCO BRANDS \| 2026 PROXY STATEMENT **77**

------

oAs of March 23, 2026, the potential dilution under the Plan, as adopted in 2022 and amended in 2023 and 2025 was 13.92 percent.

oAs of March 23, 2026, the shares requested for the Plan as amended would increase our total potential dilution to 17.09 percent.

oThe Plan prohibits recycling of shares that are surrendered or withheld to pay a stock option exercise price or withholding taxes. These shares cannot be added back to the shares available under the Plan.

oGiven that our equity awards in recent years have been in the form of restricted stock units and performance-based stock units (i.e. full-value awards) and we do not intend to issue stock options or stock appreciation rights (SARs) going forward, we believe that eliminating a fungible share counting ratio for new awards is appropriate to simplify the Plan.

Approval of the amendment requires the affirmative vote of a majority of votes cast at the Annual Meeting. If stockholders do not approve the amendment, awards may continue to be granted under the existing Plan, but no additional equity awards may be granted once the current share reserve is exhausted.

**Plan Amendment History**

The Plan was previously filed as Annex A to the definitive proxy statement on Schedule 14A filed with the SEC on April 1, 2022 and amended on May 16, 2023 and May 20, 2025 to increase the share pool.

In addition to the Plan, the Company currently also maintains both the 2019 ACCO Brands Corporation Incentive Plan (the "2019 Plan") and the ACCO Brands Corporation Incentive Plan as Amended and Restated effective May 12, 2015 (the "2015 Plan"). The 2019 Plan and the 2015 Plan are collectively known as the "Prior Plans." No additional shares are available for grant under either of the Prior Plans, but there are outstanding awards under the Prior Plans, and to the extent such awards are forfeited or expire, the shares will be added to the shares available for grant under the Plan.

As proposed to be amended, the total number of shares of common stock available for awards under the Plan may not exceed the sum of (i) 4,100,000 shares authorized pursuant to the proposed amendment to the Plan, (ii) 4,550,000 shares authorized pursuant to the second amendment to the Plan, (iii) 8,275,000 shares authorized pursuant to the first amendment of the Plan, (iv) 7,250,000 shares originally authorized under the Plan, (v) 469,631 shares that remained available for awards under the 2019 Plan as of the original effective date of the Plan, May 17, 2022 (the "Original Effective Date"), and (vi) the number of shares subject to outstanding awards under the Prior Plans as of the Original Effective Date that thereafter cease for any reason to be subject to such awards (other than in connection with the exercise or settlement of the awards, including shares withheld to satisfy the exercise price or tax withholding obligations associated with the exercise, vesting or settlement of such awards) on the basis of: (A) one share for each share subject to a stock option or stock appreciation right, and (B) 2.00 shares for each share subject to a full value award under the 2019 Plan or 2.06 shares for each share subject to a full value award under the 2015 Plan.

Under the Plan as currently in effect, each full value award granted reduces the number of shares available for issuance by 2.00 shares and each stock option and SAR granted reduces the number of share available for issuance by 1.00 share. Shares returned are added back to the share reserve using the same share-counting ratio, except that, with respect to shares underlying awards granted under the

**78** ACCO BRANDS \| 2026 PROXY STATEMENT

------

2015 Plan, shares returned are added back to the share reserve on the basis of 1.00 share for each underlying an option or SAR and 2.06 shares for each share underlying a full value award.

This proposed amendment would eliminate this fungible share counting ratio for awards made after the amendment effective date, such that if the amendment is approved, all awards granted on or after May 19, 2026 will reduce the number of shares available for issuance by 1.00 share for every 1.00 share issued and shares granted after the effective date of this proposal, if returned, will be added back to the share reserve at the rate of 1.00 share for every 1.00 share issued. Shares granted prior to the effective date of this proposal, if returned, will be added back to the share reserve at the rate at which they were deducted from the share reserve under the terms of the Plan as currently in effect.

If approved, the new shares will be added to the 510,325 shares that remain available for issuance under the Plan for a total of 4,610,325 shares in reserve for future grants.

The principal features of the Plan are highlighted below.

**Overview**

Our incentive plans are a vital component of our compensation program. The purpose of the Plan is to provide incentives linked to the creation of stockholder value and the achievement of certain long-term strategic and financial goals through a variety of equity-based and cash awards designed to attract, retain and motivate the best available employees and non-employee directors. Historically, our equity award program consisted of grants of performance share units ("PSUs"), restricted stock units ("RSUs") and non-qualified stock options ("NQSOs"). For 2025, our equity award program consisted of grants of PSUs and restricted stock units RSUs only. We ceased granting stock options in 2023 and do not intend to issue stock option or SAR awards going forward, as we believe the current mix is a more judicious use of the finite shares available under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•PSUs represent the principal component of long-term equity incentive compensation for our named executive officers. These grants are indicative of our pay-for-performance philosophy, as discussed under the heading "Compensation Discussion and Analysis—Discussion and Analysis—Executive Compensation Philosophy." PSUs focus management on long-term financial performance, aligning management and stockholders' interests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•RSUs serve as important management retention tools and further align management with stockholders' interests, including our stockholders' interest in share price appreciation.

**Important Features of the Plan**

The Plan includes the following important features that are designed to serve our stockholders' interests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*One-year minimum vesting*. The period required for vesting of an equity-based award under the Plan may not be less than one year, other than as the Compensation and Human Capital Committee may otherwise specify in the case of the death or disability, or where awards have been assumed by the Company in connection with a merger or other business combination, or as otherwise may apply in the event of a change in control under the Plan. In addition, awards covering up to five percent of the shares available under the Plan may have a vesting period of less than one year; provided, that awards granted to non-employee directors on the date of an annual stockholder meeting that vest at the next annual stockholder meeting will be

ACCO BRANDS \| 2026 PROXY STATEMENT **79**

------

deemed to have a vesting period of one year even if the period of time between stockholder meetings is less than one year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Limited discretionary authority to accelerate vesting*. The Compensation and Human Capital Committee will not have discretion to accelerate the vesting of any portion of an award, except in cases of termination by reason of death or disability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Non-employee director compensation*. The value (determined under applicable accounting standards for financial reporting purposes) of a non-employee director's total compensation from the Company in a calendar year, including awards from the Plan, may not exceed $500,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Dividends and dividend equivalents.* Rights to dividends and dividend equivalents may be made a part of certain awards, subject to such terms, conditions and restrictions as the Compensation and Human Capital Committee may establish. Any crediting of dividends or dividend equivalents shall be subject to the same restrictions and conditions as the underlying award. Dividends or dividend equivalents credited with respect to awards subject to the achievement of performance goals will only be paid to the extent the award vests and the performance goals are achieved, and dividends or dividend equivalents with respect to any award subject to a time-based vesting schedule will only be paid to the extent the award vests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*No liberal share recycling*. Shares that are surrendered or withheld to pay an award's exercise price or withholding taxes cannot be added back to the shares available under the Plan. Likewise, any shares reacquired by the Company with the amount received from stock option exercises will not be added to the pool of available shares under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*No repricing or cash buy-out without stockholder approval*. No stock option or SAR may be re-priced or substituted or exchanged for cash or as consideration for the grant of a new award with a lower exercise price without stockholder approval, except as may be permitted in connection with an event described below under the heading "Adjustments" or in the event of a change in control. (However, options and SARs may be settled by a cash payment that does not exceed the difference between the fair market value of the shares subject to the option or SAR and the strike price.)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*No liberal change of control definition*. The Plan does not have a "liberal" change-in-control definition. A change in control is deemed to occur only upon completion, rather than stockholder approval, of a transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*No evergreen provision*. The number of shares available for grant under the Plan is capped, and there is no formula providing for any automatic increase in the number of shares available.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*No discounted stock options or SARs*. The Plan prohibits the granting of stock options or SARs at strike prices that are less than the fair market value of our common stock on the date of grant.

**Historical Grant and Governance Practice Highlights**

Our historical grant and governance practices are set forth below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Three-year vesting and performance periods.* Historically, annual equity grants to executive officers, including our CEO, have generally been subject to a minimum three-year vesting

**80** ACCO BRANDS \| 2026 PROXY STATEMENT

------

period. RSUs are subject to a minimum three-year cliff vesting period and PSU awards are subject to a cumulative three-year performance period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*High proportion of CEO's compensation subject to performance conditions.* In 2025, 67 percent of our CEO's target equity-based compensation was subject to achievement of financial performance measures. In 2025, 85.2 percent of our CEO's total target compensation was variable and at risk as it was subject to the achievement of financial performance measures and share price appreciation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*No hedging or pledging*. Our insider trading policy, which applies to shares acquired through grants made under the Plan, prohibits our directors and employees from engaging in hedging transactions or pledging their shares. Further information on this policy is provided under the heading "Compensation Discussion and Analysis—Discussion and Analysis—Prohibitions on Hedging, Pledging and Similar Transactions."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Post vesting/exercise holding requirements*. Our executive officers are required to hold a specified number of shares or dollar value of equity granted to them under the Plan. Prior to attaining the required threshold level, they may liquidate no more than 50 percent of the net shares remaining after the exercise of a stock award or the vesting of shares granted under the Plan; after attaining the required threshold, they may sell shares, subject to our insider trading policy, so long as they maintain the required threshold number of shares or dollar value. Further information on this policy, is provided under the heading "Compensation Discussion and Analysis—Discussion and Analysis—Executive Stock Ownership Guidelines."

**Description of the Plan**

The following description of the Plan summarizes the material terms of the Plan, including as amended by the proposed amendment to the Plan; however, it does not purport to be complete and is qualified in its entirety by reference to the Plan which was previously filed as Annex A to the definitive proxy statement on Schedule 14A filed with the SEC on April 1, 2022 and to the form of the proposed amendment to the Plan, which is attached as Appendix A to this proxy statement.

**Term and Effective Date**

The Plan became effective on May 17, 2022, the date our stockholders approved the Plan. No awards may be made or granted after the tenth anniversary of the Plan's effective date.

**Administration**

The Plan is administered by the Compensation and Human Capital Committee, which is composed entirely of directors who are "non-employee directors" under the rules adopted under Section 16 of the Exchange Act, and are independent under the rules of the NYSE. The Compensation and Human Capital Committee has the power and authority to construe and interpret the Plan, select the individuals who will receive awards from among eligible participants, and determine the form, amount and terms of those awards, except that the amount, form, and timing of the grant of awards to non-employee directors shall be determined by the full Board of Directors unless the Board otherwise delegates any or all of these functions to a committee or committees of the Board. The Compensation and Human Capital Committee has the power to delegate to one or more officers of the Company the right to designate employees (other than the employee himself or herself or executive officers of ACCO Brands) to receive awards, subject to certain restrictions and provided that the total number of shares or cash payable under such awards are determined by the Compensation and Human Capital Committee.

**Eligibility**

Employees of the Company or its subsidiaries, including executive officers, selected by the Compensation and Human Capital Committee as well as non-employee directors of the Company are eligible to receive awards under the Plan. The Compensation and Human Capital Committee anticipates

**82** ACCO BRANDS \| 2026 PROXY STATEMENT

that individuals who are vice president level or above will receive annual grants of awards under the Plan. The approximate number of employees in that group is less than 50. In addition, the Compensation and Human Capital Committee anticipates that discretionary grants will be made on an annual basis to certain high potential employees who are director level and above. The approximate number of employees eligible to receive a discretionary cash grant is 200, and annually between 0 and 50 discretionary grants are made. The Board anticipates that all non-employee directors will be eligible to participate in the Plan as of May 19, 2026.

**Plan and Award Limitations and Restrictions**

*Reserved shares.* The total number of shares of common stock available for awards under the Plan currently may not exceed (i) 510,325 shares, plus (ii) the number of shares subject to outstanding awards under the Plan and Prior Plans as of May 17, 2022, that later terminate, expire, or are forfeited for any reason other than by exercise or settlement of the award (including shares withheld to satisfy exercise price or tax-withholding obligations). Such returning shares will be added back to the share reserve using the same share-counting ratios in effect at the time the original award was granted - namely: (A) one share for each share subject to a stock option or stock appreciation right, and (B) 2.00 shares for each share subject to a full-value award under the 2019 Plan (2.06 shares for each share subject to a full value award under the 2015 Plan). These historical share-counting ratios apply only to awards granted prior to the approval of this amendment.

If the amendment is approved, the total number of shares of common stock available for awards under the Plan will be increased to 4,610,325. Going forward, all awards granted on or after the effective date of the amendment will be counted on the basis of (A) one share for each share subject to a stock option or stock appreciation right, and (B) one share for each share subject to a full-value award. In addition, shares subject to outstanding awards under the Plan and Prior plans that terminate, expire or are forfeited after the effective date of the amendment will continue to be added back to the share reserve at the rate at which they were deducted from the share reserve, as described above. As of March 23, 2026, the number of shares subject to existing awards under the Plan and Prior Plans that could again become available for awards under the Plan is 14,407,123.

*Non-employee director compensation*. The value (determined under applicable accounting standards for financial reporting purposes) of a non-employee director's total compensation from the Company in a calendar year, including awards from the Plan, may not exceed $500,000.

*One-year minimum vesting*. The period required for vesting of an equity-based award under the Plan may not be less than one year, other than as the Compensation and Human Capital Committee may otherwise specify in the case of the death or disability, or where awards have been assumed by the Company in connection with a merger or other business combination, or as otherwise may apply in the event of a change in control under the Plan. In addition, awards covering up to five percent of the shares available under the Plan may have a vesting period of less than one year. Awards granted to non-employee directors on the date of an annual stockholder meeting that vest at the next annual stockholder meeting will be deemed to have a vesting period of one year even if the period of time between stockholder meetings is less than one year.

*No repricing or cash buy-out without stockholder approval.* No stock option or SAR may be re-priced or substituted or exchanged for cash or as consideration for the grant of a new award with a lower exercise price without stockholder approval, except as may be permitted in connection with an event described below under the heading "Adjustments" or in the event of a change in control. (However, options and SARs may be settled by a cash payment that does not exceed the difference between the fair market value of the shares subject to the option or SAR and the strike price.)

ACCO BRANDS \| 2026 PROXY STATEMENT **83**

------

*Clawback and cancellation.* All awards made under the Plan (including awards that are subject to time-based or performance-based conditions), and shares of common stock issued thereunder, are subject to applicable ACCO Brands' clawback or recoupment policies as in effect from time-to-time and any similar policies required by law or regulation. Unless otherwise provided in an award agreement, a participant's award or payments thereunder will be subject to cancellation or recoupment in instances where the participant is terminated for cause or has violated certain policies or codes of conduct, has breached a restrictive covenant applicable to the participant or has engaged in misconduct or conduct that is detrimental to the business or reputation of the Company. The Company's current clawback policy provides that an executive officer must forfeit or reimburse the Company for cash or equity incentive compensation paid or payable to the executive officer if either the payment was based on the achievement of financial results that were subsequently restated (regardless of whether the officer was responsible for the restatement) and a lower amount would have been paid to the executive officer based on the restated results. Further, the Company's current clawback policy provides that an executive may be required to forfeit or reimburse the Company for cash or equity incentive compensation paid or payable to the executive officer if the Board determines the officer engaged in willful or intentional misconduct. Further information regarding the clawback policy is provided under the heading "Compensation Discussion and Analysis—Discussion and Analysis—Recoupment or Forfeiture of Incentive Payments Policy."

**Share Recycling Provisions and Limitations**

The Plan contains the following provisions and limitations with respect to shares that may again become available for awards:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Any shares of common stock covered by an award that are not issued or are canceled because the award expires or is forfeited or terminated (for example, for a failure to vest or to achieve applicable performance conditions) will be again available for award and will not be considered as having been made subject to an award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Any shares surrendered or withheld as payment for all or a portion of the exercise price of a stock option, or surrendered or withheld in satisfaction of withholding taxes with respect to an award, will not be again available for award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The exercise or settlement of an SAR will reduce the shares available under the Plan by the total number of shares to which the exercise or settlement relates, and not just the net amount of shares actually issued upon exercise or settlement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Any shares that are reacquired by the Company with the amount received upon the exercise of stock options will not be added to the pool of shares available for awards under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Awards partially or wholly settled in cash will only reduce the number of shares available for issuance under the Plan to the extent shares are issued.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Shares of common stock issued in connection with awards that are assumed, converted or substituted pursuant to a merger or other business combination will not reduce the number of shares available for issuance under the Plan.

The number of shares reserved for issuance under the Plan and the limitations described above may be adjusted by the events described below under the headings "Adjustments" and "Change in Control".

**Award Forms**

Under the Plan, the Compensation and Human Capital Committee may grant various types of awards, including the following:

**84** ACCO BRANDS \| 2026 PROXY STATEMENT

------

*Stock options.* Stock option awards may be either incentive stock options ("ISOs") or NQSOs. Stock options are exercisable in whole or in part following the completion of a required employment period (or service period for a non-employee director) and the satisfaction of any performance objectives as specified in the discretion of the Compensation and Human Capital Committee. Stock options expire no later than the tenth anniversary of the date of grant, and the exercise price of stock options may not be less than the fair market value of a share of our common stock on the date of grant. As of March 23, 2026, the fair market value of a share of our common stock, based on the average of the high and low sales price as reported on the NYSE on that date, was $2.94 per share.

*Stock appreciation rights.* SARs may be granted independently of any stock option or in tandem with all or any part of a stock option. SARs are exercisable in whole or in part following the completion of a required employment period (or service period for a non-employee director) and the satisfaction of any performance objectives as specified in the discretion of the Compensation and Human Capital Committee. Generally, upon exercise, an SAR entitles a participant to receive (in cash, shares of common stock or a combination thereof) the excess of the fair market value of a share of common stock on the date the SAR was exercised over its exercise price. SARs will expire no later than the tenth anniversary of the date of grant, and the exercise price of an SAR may not be less than the fair market value of a share of our common stock on the date of grant.

*Restricted stock and performance shares.* Shares of common stock that are subject to restrictions on transfer or other incidents of ownership as established by the Compensation and Human Capital Committee, including, in the case of performance shares, the satisfaction of performance criteria, may be awarded under the Plan. For restricted stock, a "restriction period" will apply during which time the shares are subject to forfeiture by the participant if, for example, the participant's employment or service terminates. During a restriction period, the holder of restricted stock will be entitled to exercise full voting rights.

*Restricted and performance stock units.* RSUs and PSUs are fixed or variable share denominated units subject to such terms and conditions, including vesting, time of payment and, in the case of PSUs, the satisfaction of performance criteria, as the Compensation and Human Capital Committee may determine. RSUs and PSUs are valued in whole or in part by reference to, or otherwise based on, the fair market value of the Company's common stock, and may be paid in shares of common stock, cash or a combination of both.

*Dividends and dividend equivalents.* Rights to dividends and dividend equivalents may be made a part of certain awards, subject to such terms, conditions and restrictions as the Compensation and Human Capital Committee may establish. Any crediting of dividends or dividend equivalents shall be subject to the same restrictions and conditions as the underlying award. Dividends or dividend equivalents credited with respect to awards subject to the achievement of performance goals will only be paid to the extent the award vests and the performance goals are achieved, and dividends or dividend equivalents with respect to any award subject to a time-based vesting schedule will only be paid to the extent the award vests.

*Cash-based awards.* Awards denominated in cash may be granted under the Plan, or under other multi-year bonus plans or incentive plans established under the Plan, that may be earned and payable based on the satisfaction of time or performance-based criteria designated by the Compensation and Human Capital Committee.

ACCO BRANDS \| 2026 PROXY STATEMENT **85**

------

*Other incentive awards.* The Compensation and Human Capital Committee may grant other types of awards under the Plan whose value, in whole or in part, is based on the Company's common stock or other factors.

**Performance Criteria**

Performance awards, such as performance shares and PSUs, represent the right to receive shares of common stock, cash or a combination thereof, contingent on the achievement of performance or other objectives during a specified period as the Compensation and Human Capital Committee may determine. Awards intended to be "performance-based compensation" will be conditioned on the achievement of criteria, measures or goals established by the Compensation and Human Capital Committee. The Compensation and Human Capital Committee has the sole discretion to adjust the determinations of the value and degree of attainment of the performance goals including the discretion to reduce the amount of an award that would otherwise vest or be paid based on the achievement of the performance goals. The Compensation and Human Capital Committee also retains the sole discretion to adjust such performance goals to reflect changes in circumstances that occur after the goals are established, or to reduce or increase the amount of the payment and/or vesting of an award relative to the performance goals.

**Participant Termination Provisions**

Each participant's award agreement will specify the treatment of the award in the event of the participant's termination of employment (or service as a non-employee director), as determined by the Compensation and Human Capital Committee at the time of grant. Generally, awards will be forfeited and will not be paid if the awards or portions thereof remain unvested or subject to restriction or forfeiture as of the date a participant's employment or service as a non-employee director with the Company ceases. Except as otherwise determined by the Compensation and Human Capital Committee in the award agreement, if a participant's employment or service as a non-employee director with the Company ends due to death, disability, retirement or due to a divestiture (as defined in the Plan) that is not a change in control (as defined in the Plan), then any awards then held by a participant will vest as follows:

*Death or Disability*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•All options and SARs held by the participant will immediately become vested and exercisable, and will continue to be exercisable for the lesser of five years or the remaining term of the options and SARs, unless death occurs in the final year of the term, in which case the exercise of NQSOs or SARs can occur for up to one additional year from the date of death; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•All restricted stock or RSUs held by the participant will become unrestricted or nonforfeitable and payable; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•A prorated portion of all performance shares and PSUs held by the participant will become unrestricted or nonforfeitable and payable, as applicable, with respect to the number of performance shares or PSUs that could have become earned and vested based on the deemed attainment of performance at the target level, with such number of performance shares or PSUs prorated based on the portion of the performance period that elapsed through the date of the participant's termination.

*Retirement*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•All options and SARs held by the participant will continue to vest and be exercisable in accordance with their original vesting terms (as if the termination of employment or service had

**86** ACCO BRANDS \| 2026 PROXY STATEMENT

------

not occurred) and shall remain exercisable until the expiration of the term of the option or SAR; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•All restricted stock or RSUs held by the participant will continue to vest in accordance with their original vesting terms (as if the termination of employment or service had not occurred); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•A prorated portion of all performance shares and PSUs held by the participant will become unrestricted or nonforfeitable and payable, as applicable, with respect to the number of performance shares or PSUs that would have become earned and vested based on the actual attainment of performance objectives set forth in the award over the applicable performance period, with such number of performance shares or PSUs prorated based on the portion of the performance period that elapsed through the date of the participant's termination.

*Divestiture*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Upon termination due to a divestiture occurring after the first anniversary of the date of grant, all options and SARs held by a participant will become immediately vested and exercisable with respect to a prorated portion of the number of shares subject to the options or SARs, and will remain exercisable until the expiration of the term of the option or SAR, with such proration based on the portion of the restriction period that elapsed through the date of the participant's termination; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Upon termination due to a divestiture occurring after the first anniversary of the date of grant, all restricted stock and RSUs held by a participant will become unrestricted or nonforfeitable and payable with respect to a prorated portion of the number of shares subject to the restricted stock awards and RSUs with such proration based on the portion of the restriction period that elapsed through the date of the participant's termination; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Upon termination due to a divestiture occurring after the first anniversary of the date of grant, a prorated portion of all performance shares and PSUs held by the participant will become unrestricted or nonforfeitable and payable, as applicable, with respect to the number of performance shares or PSUs that could have become earned or vested based on the deemed attainment of performance at the target level, with such number of performance shares or PSUs prorated based on the portion of the performance period that elapsed through the date of the participant's termination.

Generally, a "divestiture" is a transaction (that is not a change in control) by which the subsidiary of the Company that is the participant's principal employer or service recipient ceases to be a subsidiary of the Company.

*Involuntary Termination Without Cause*

For an employee who incurs an involuntary termination of employment without cause during the six-month period preceding the specified vesting date (but after the first anniversary of the grant date), a prorated portion of any restricted stock and RSUs held by the employee will become unrestricted or nonforfeitable and payable, respectively, based on the period of restriction elapsed through the date of the participant's termination.

For an employee who incurs an involuntary termination of employment without cause during the last six months of a performance period (but after the first anniversary of the grant date), a portion of any performance shares and PSUs held by the employee will become unrestricted or nonforfeitable and payable, as applicable, with respect to the number of performance shares or PSUs that would have become earned and vested based on the actual attainment of performance objectives set forth in the award over the applicable performance period, with such number of performance shares or PSUs

ACCO BRANDS \| 2026 PROXY STATEMENT **87**

------

prorated based on the portion of the performance period elapsed through the date of the participant's termination.

The Plan provides that the Compensation and Human Capital Committee is not authorized to waive or accelerate vesting of any award except in cases of termination by reason of death or disability.

**Adjustments**

In the event of a corporate transaction involving the Company, such as an extraordinary cash dividend, recapitalization, reorganization, merger, consolidation or spin-off, the Compensation and Human Capital Committee may adjust outstanding awards as it deems appropriate in order to prevent dilution or enlargement of participants' rights under the Plan.

**Change in Control**

*Replacement awards-no immediate vesting*. Awards will not vest upon a change in control of the Company (as defined in Section 2(j) of the Plan) if a "Replacement Award" as defined under Section 17.1(a)(ii) of the Plan (which may include the original award) is issued in substitution for the award. Where Replacement Awards are issued, vesting will be accelerated where a participant incurs an involuntary termination other than due to cause or disability, or resigns for good reason (as defined in the Plan) during the 24 months following the change in control.

*Vesting if no replacement award*. To the extent a Replacement Award is not provided to a participant, or if a participant incurs an involuntary termination other than due to cause or disability within 180 days prior to a change in control, upon a change in control, all outstanding options and SARs will become immediately exercisable; all restricted stock will become unrestricted or nonforfeitable; all RSUs will become fully vested and paid out in cash or common stock; and all performance-based awards will become payable in full, with the performance objectives applicable to such award deemed satisfied at the target level of performance for the entire performance period (or a greater amount if determined by the Compensation and Human Capital Committee to have been earned based on performance through the date of the change in control).

Individual award agreements may provide for different treatment on a change in control.

**Amendment and Termination**

Our Board of Directors may, at any time and from time to time, alter, amend, modify, suspend or terminate the Plan, subject to the receipt of stockholder approval for certain types of amendments. No amendment, suspension, modification or termination of the Plan may materially adversely affect any award previously granted under the Plan without the written consent of the participant holding such award.

**U.S. Federal Income Tax Consequences**

The following is a brief summary of the principal United States federal income tax consequences of awards that may be granted under the Plan. The summary is based on current U.S. federal income tax laws and interpretations thereof, all of which are subject to change at any time, possibly with retroactive effect. The summary is not intended to be exhaustive.

*Non-qualified stock options and SARs*. A participant who receives an NQSO or SAR does not recognize taxable income upon the grant of the NQSO or SAR, and the Company is not entitled to a tax deduction on the date of grant. The participant will recognize ordinary income upon the exercise of the NQSO or SAR in an amount equal to the excess of the fair market value of the NQSO or SAR shares on the

**88** ACCO BRANDS \| 2026 PROXY STATEMENT

------

exercise date over the NQSO or SAR exercise price stated in the award. Such income will be treated as compensation to the participant subject to applicable tax withholding requirements. The Company generally is entitled to a tax deduction in an amount equal to the amount that is taxable to the participant as ordinary income in the year that the income is taxable to the participant, subject to the discussion below. Any appreciation in value of the shares after the time of exercise will be taxable to the participant as capital gain upon sale of the shares and will not result in a deduction by the Company.

*Incentive stock options*. An employee who receives an ISO does not recognize taxable income upon the grant or exercise of the ISO, unless the ISO is exercised more than three months after termination of employment (one year in cases of death or disability) and the Company is not entitled to a tax deduction on the date of exercise. The difference between the ISO exercise price and the fair market value of the ISO shares on the date of exercise, however, will be treated as a tax preference item for purposes of determining the alternative minimum tax liability, if any, of the employee in the year of exercise. The Company will not be entitled to a deduction with respect to any item of tax preference.

An employee will recognize gain or loss upon the disposition of shares acquired from the exercise of an ISO. The nature of the gain or loss depends on how long the ISO and the ISO shares were held. If the ISO shares are not disposed of pursuant to a disqualifying disposition, the employee will recognize long-term capital gain or capital loss depending on the selling price of the shares. A "disqualifying disposition" is a disposition that occurs within two years from the date the ISO was granted or, if later, one year from the date of ISO exercise. If ISO shares are sold or disposed of as part of a disqualifying disposition, the employee must recognize ordinary income in an amount equal to the lesser of the amount of gain recognized on the sale, or the difference between the fair market value of the ISO shares on the date of exercise and the ISO exercise price. Any additional gain will be taxable to the employee as a long-term or short-term capital gain, depending on how long the shares were held after exercise of the ISO. The Company generally is entitled to a deduction in computing its federal income taxes for the year of a disqualifying disposition in an amount equal to any amount taxable to the employee as ordinary income, subject to the discussion below.

*Restricted stock, performance shares, RSUs and PSUs*. A participant who receives shares of restricted stock or performance shares will generally be taxed on the value of the shares at the time they either are no longer subject to a substantial risk of forfeiture, or are transferable. A participant may instead elect under Section 83(b) of the Code to be taxed on the value of the shares at the time the award is issued, but in such case will not be entitled to an offsetting deduction if the shares are subsequently forfeited. A participant who receives an RSU or PSU will be subject to income tax on the value of the shares issued in settlement of the RSU or PSU at the time the shares are issued (or the amount of cash issued in lieu of shares). When a participant sells or otherwise disposes of shares received, the difference between the proceeds received for the shares and the amount of income realized as described above will generally constitute a capital gain or loss. The Company will generally be entitled to a deduction for the amount of ordinary income realized by a participant as described above (including any income realized upon making a Section 83(b) election), subject to the discussion below.

*Cash-based awards.* Awards settled by a cash payment will be taxable to the participant as ordinary income, and deductible by the Company at the time of payment, subject to the discussion below.

Pursuant to Section 162(m) of the Code, as amended by the Tax Cuts and Jobs Act of 2017 (the "Act"), the Company will not be entitled to deduct compensation paid to any "covered employee" — generally any person who either is, or at any time has been, a named executive officer — to the extent the total compensation paid to the covered employee in any year exceeds $1,000,000.

**Plan Benefits**

Because grants under the Plan will be discretionary, the Company cannot now determine the number of shares that will be granted to any particular executive officer, to all executive officers as a group or to non-executive officer employees or directors as a group. The number of such shares will be determined by the Compensation and Human Capital Committee or the Board from time to time in accordance with the terms of the Plan. Please refer to the "*Grants of Plan-Based Awards*" table for awards made during the most recent fiscal year under the Plan to our named executive officers and the table under "*Director Compensation*" for awards made to our non-employee directors.

# Additional Information

## Questions and Answers about this Proxy Statement
**Why is ACCO Brands distributing this Proxy Statement?**

Our Board of Directors is soliciting proxies for use at the Annual Meeting to be held on Tuesday, May 19, 2026, beginning at 9:30 a.m. Central Time, via a live audio webcast. In order to solicit your proxy, we must furnish you with this Proxy Statement, which contains information about the matters to be voted upon at the Annual Meeting.

**What is the purpose of the Annual Meeting?**

The purpose of the Annual Meeting is for stockholders to act upon the following matters outlined in the Notice and described in this Proxy Statement: (1) the election of nine directors, (2) the ratification of KPMG LLP as our independent registered public accounting firm for 2026, (3) a non-binding advisory vote on the compensation of our named executive officers, (4) approval of an amendment to the 2022 ACCO Brands Corporation Incentive Plan to increase the number of shares reserved for issuance and eliminate fungible share counting provisions with respect to new awards; and (5) such other business as may properly come before the meeting or any adjournment or postponement thereof. In addition, management will be available to respond to questions from stockholders.

**Why did I receive a Notice in the mail regarding the availability of proxy materials on the Internet instead of a full set of proxy materials?**

Pursuant to rules adopted by the SEC, we are providing access to our proxy materials via the Internet. The Notice we sent to our stockholders provides instructions on how to access and review this Proxy Statement and our Annual Report online, as well as how to vote online prior to the meeting. Providing proxy materials electronically significantly reduces the printing and mailing costs associated with the distribution of printed copies of our proxy materials to our stockholders and is more environmentally friendly.

If you receive a Notice, you will not receive a printed copy of the proxy materials by mail unless you request one. All stockholders have the ability to access the proxy materials on the website referred to in the Notice or request a printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request printed copies may be found in the Notice. In addition, stockholders may request proxy materials in printed form by mail on an ongoing basis.

**Who is entitled to vote?**

Only stockholders who own ACCO Brands common stock of record at the close of business on March 23, 2026 are entitled to vote. Each holder of common stock is entitled to one vote per share. There were 92,257,794 shares of common stock outstanding on March 23, 2026.

**What is the difference between being a record holder and holding shares in street name?**

A record holder holds shares in his or her own name. Shares held in "street name" are shares that are held in the name of a bank, broker or other nominee on a person's behalf. If the shares you own are held in "street name," the bank, broker or other nominee will vote your shares according to your instructions. Under the rules of the New York Stock Exchange ("NYSE"), if you do not give instructions

ACCO BRANDS \| 2026 PROXY STATEMENT **93**

------

to your bank, broker or other nominee, it will still be able to vote your shares on any "discretionary" items but will not be allowed to vote your shares with respect to any "non-discretionary" items.

Only the ratification of KPMG LLP as our independent registered public accounting firm (Proxy Item 2) is considered to be a discretionary item under the NYSE rules, and your bank, broker or other nominee will be able to vote on that item even if it does not receive voting instructions from you, so long as it holds your shares in its name. **The election of directors (Proxy Item 1), the advisory vote on the compensation of our named executive officers (Proxy Item 3) and approval of** the **amendment to the 2022 ACCO Brands Corporation Incentive Plan (Proxy Item 4) are non-discretionary items. Therefore, if you hold your shares in "street name," your bank, broker or other nominee cannot vote your shares with respect to these items unless it receives your voting instructions.** Non-discretionary proxy items as to which no voting instructions are received are counted as "broker non-votes." Broker non-votes are shares that are held in "street name" by a bank, broker or other nominee that indicates on its proxy that it does not have or did not exercise discretionary authority to vote on a particular matter.

**How do I vote?**

Stockholders of record can vote by telephone or through the Internet by following the instructions printed on the accompanying proxy card or in the Notice, or by filling out and returning the accompanying proxy card. Stockholders may also vote at the meeting by following the procedures for voting during the virtual meeting. Instructions on how to vote during the virtual meeting will be available online during the registration process at https://web.viewproxy.com/ACCO/2026 in the document entitled FAQ.

Stockholders who hold shares in "street name" can vote by following the voting instructions in the materials received from their bank, broker or other nominee. The availability of telephone and Internet voting for stockholders who hold shares in "street name" will depend on the voting processes of your bank, broker or other nominee. Therefore, we recommend that you follow the voting instructions in the materials you receive from your bank, broker or other nominee.

**How will my proxy be voted?**

Your proxy, when properly signed and returned, or processed by telephone or through the Internet, and not revoked, will be voted in accordance with your instructions. We are not aware of any other matter that may be properly presented at the Annual Meeting other than the election of directors, the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for 2026, the advisory vote on the compensation of our named executive officers, and approval of the amendment to the 2022 ACCO Brands Corporation Incentive Plan. If any other matter is properly presented at the meeting, the persons named in the enclosed form of proxy will have the authority to vote on such matters at their discretion.

**What constitutes a quorum?**

The holders of a majority in voting power of the issued and outstanding common stock of the Company present either in person, or by remote communication, if applicable, or represented by proxy at the Annual Meeting will constitute a quorum. Proxies received but marked as abstentions and broker non-votes will be included in the calculation of the number of shares considered to be present at the Annual Meeting. If less than a majority in voting power of the outstanding shares of common stock are represented at the Annual Meeting, a majority of the shares so represented may adjourn the Annual Meeting to another date, time or place.

**What if I submit my proxy or voting instruction but don't specify how to vote my shares?**

If you hold shares in your name and sign and return your proxy or cast your proxy by telephone or through the Internet, but do not specify how you want your shares to be voted, the persons named as proxies will vote in accordance with the recommendations of the Board of Directors. In summary, the Board of Directors recommends a vote:

(1)FOR the election of each director nominee (Proxy Item 1);

(2)FOR the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for 2026 (Proxy Item 2);

(3)FOR the advisory vote on the compensation of our named executive officers (Proxy Item 3); and

(4)FOR approval of an amendment to the 2022 ACCO Brands Corporation Incentive Plan to increase the number of shares reserved for issuance and eliminate fungible share counting provisions with respect to new awards (Proxy Item 4).

If you hold shares in "street name," your bank, broker or other nominee cannot vote your shares on non-discretionary items to be brought for a vote at the Annual Meeting. As a result, if you do not provide instructions on how you want your shares to be voted, your bank, broker or other nominee will not have the authority to vote on any proxy item except Proxy Item 2 (ratification of independent registered public accounting firm).

**How do I attend the Annual Meeting?**

Any stockholder of record as of the record date (March 23, 2026) and those who hold a valid proxy from a stockholder of record can attend the Annual Meeting online by first registering at https://web.viewproxy.com/ACCO/2026.You must register at least one hour prior to the start time of the Annual Meeting.

guidance on how to submit questions for the Annual Meeting, and our procedures for responding to those questions, will be available at https://web.viewproxy.com/ACCO/2026.

**What if I have technical difficulties accessing the virtual meeting?**

If you encounter any technical difficulties during registration or check-in, or during the meeting, please contact technical support via e-mail at <u>VirtualMeeting@viewproxy.com</u> or call 866-612-8937.

**Can I attend the Annual Meeting if I vote by proxy?**

Yes. Attending the meeting via the live audio webcast does not revoke your proxy unless you cast a vote at the meeting. Please note that attendance at the Annual Meeting is limited to stockholders of record as of the close of business on March 23, 2026, the record date, and to those who hold a valid proxy from a stockholder of record.

**How can I revoke my proxy?**

You may revoke your proxy at any time before it is actually voted by giving written notice to our Corporate Secretary at the address listed under "Corporate Governance—Stockholder Communication," or by delivering a later-dated proxy by mail or voting by telephone or Internet at a later date, which automatically revokes your earlier proxy if one of those methods was used for your initial proxy submission. If you attend the Annual Meeting via the live audio webcast, you may vote at the meeting which will override any previously submitted proxy.

**Will my vote be public?**

No. As a matter of policy, stockholder proxies, ballots and tabulations that identify individual stockholders are kept secret and are only available to the independent Inspector of Election and certain employees who have an obligation to keep your votes secret.

**How many votes are needed to elect directors and how will votes be counted?**

Each nominee for director will be elected to the Board of Directors (Proxy Item 1) if the votes cast for such nominee's election exceeds the votes cast against such nominee's election (with abstentions and broker non-votes not counted as a vote cast for or against that nominee's election). **Please note that if you hold your shares in "street name," your bank, broker or other nominee will not be permitted to vote your shares on Proxy Item 1 (election of directors) absent specific instructions from you. Therefore, it is important that you follow the voting instructions on the form that you receive from your bank, broker or other nominee.** 

You may vote for or against each of the nominees for the Board of Directors, or you may abstain. If you abstain, your shares will be counted for purposes of establishing a quorum for the meeting but will have no effect on the election of the nominees. In accordance with the Company's Corporate Governance Principles, each director nominee has submitted a contingent, irrevocable resignation that the Board of Directors may accept in the event that the votes cast for the director nominee's election do not exceed the votes cast against the director nominee's election (with abstentions and broker non-votes not counted as a vote cast either for or against the director nominee's election). In that situation, the Nominating, Governance and Sustainability Committee (or a special committee consisting solely of independent directors not subject to a failed vote) would make a recommendation to the Board of Directors about whether to accept or reject the resignation, or whether to take other action. For additional information, see "Board of Directors—Election of Directors."

**How many votes are needed to approve the other matters to be voted upon at the Annual Meeting and how will votes be counted?**

With respect to each of Proxy Items 2, 3 and 4, the affirmative vote of the holders of a majority in voting power of the votes cast on the matter is necessary for the approval of such matter. Proxies marked as abstentions on Proxy Items 2, 3 and 4, and broker non-votes will have no effect on the vote for the proposal.

With respect to any other matter to be voted upon that may properly come before the meeting, you may vote for, against or abstain, with abstentions having no effect on the vote for the proposal.

**Please note that if you hold your shares in "street name," your bank, broker or other nominee will not be permitted to vote your shares on the advisory vote on the compensation of our named executive officers (Proxy Item 3), approval of the amendment to the 2022 ACCO Brands Corporation Incentive Plan (Proxy Item 4) or any other matter that may properly come before the meeting absent specific instructions from you. Therefore, it is important that you follow the voting instructions on the form that you receive from your bank, broker or other nominee.**

**What if I participate in the ACCO Brands Corporation 401(k) Plan?**

We also are making this Proxy Statement available to and seeking voting instructions from participants in the ACCO Brands Corporation 401(k) Plan who hold shares of our common stock under such plan. The trustees of the plan, as record holders of ACCO Brands common stock held in the plan, will vote whole shares attributable to you in accordance with your directions given on your voting instruction card, by telephone or through the Internet. If you hold shares of our common stock under the plan, please complete, sign and return your voting instruction card or provide voting instructions by telephone or through the Internet, as described on the voting instruction card, prior to May 13, 2026.

Article II of our By-Laws requires that we be given timely advance written notice of director nominations and other matters that an eligible stockholder wishes to present for action at an annual meeting other than those properly brought under Rule 14a-8 and included in our proxy statement. To be timely, our Corporate Secretary must receive such notice at our principal executive offices not earlier than the close of business on January 19, 2027, and not later than the close of business on February 18, 2027. Any such notice and accompanying proposal or director nomination also must be in proper form and meet the detailed disclosure and other requirements specified in Article II of our By-Laws and, with respect to director nominations, comply with the applicable requirements of Rule 14a-19 of the Exchange Act.

Any proposals, notices or nominations must be sent to the Office of the Corporate Secretary, ACCO Brands Corporation, Four Corporate Drive, Lake Zurich, Illinois 60047.

## Miscellaneous
**Cost of Soliciting Proxies**

The Company will bear the expense of soliciting proxies for this meeting, including mailing costs of the Notice, except for some costs associated with individual stockholders' use of the Internet or telephone.

ACCO BRANDS \| 2026 PROXY STATEMENT **99**

------

In addition to solicitation by mail, directors, officers and other employees may also solicit proxies personally or by telephone or other means of electronic communication but will not receive specific compensation for any such solicitation. We may reimburse brokerage firms and others holding stock in their names or in names of nominees for their reasonable out-of-pocket expenses in sending proxy materials to principals and beneficial owners.

In addition to mailing copies of the Notice and mailing or making available the related proxy materials to stockholders, we will request that persons who hold stock in their names or custody, or in the name of nominees, for the benefit of others, forward copies of these materials to the beneficial owners of our stock and request the authority to execute the proxies. Stockholders who do not intend to be present at the meeting are urged to send in their proxies without delay or vote their proxies by telephone or through the Internet. Your prompt response is greatly appreciated.

**Multiple Stockholders Having the Same Address**

To reduce costs and reduce the environmental impact of our Annual Meeting of Stockholders Meeting, we are sending only one Notice of Internet Availability of Proxy Materials or one Proxy Statement and Annual Report to the address of multiple stockholders in one envelope unless we have received contrary instructions from any stockholder at that address. This practice, known as "householding," reduces duplicate mailings, saving paper and mailing costs. Any stockholder residing at such an address who would like to receive an individual copy of the materials, or who is receiving multiple copies of our Proxy Statement and Annual Report and would prefer to receive a single copy in the future, can notify us by phone at 1-877-777-2857 or email at: <u>requests@viewproxy.com.</u> If you are a beneficial stockholder, you may contact the broker or bank where you hold the account.

**Other Matters**

The Company knows of no other matters to be submitted to the stockholders at the Annual Meeting. If any other matters properly come before the meeting, the people named in the accompanying proxy will vote the shares they represent in accordance with the recommendation of the Board of Directors.

**Financial and Other Information**

The Company has made available to you its Annual Report on Form 10-K for the year ended December 31, 2025 (the "Annual Report"), which can be accessed by following the instructions contained in the Notice of Internet Availability of Proxy Materials. The Company's Annual Report can also be accessed online at the Investor Relations section of the Company's website at www.accobrands.com.

## Appendix B: Supplemental Non-GAAP Financial Measures
**About Non-GAAP Financial Measures**

We explain below how we calculate each of our non-GAAP financial measures. This is followed by a reconciliation of our current period and historical non-GAAP financial measures to the most directly comparable GAAP financial measures.

We use our non-GAAP financial measures both to explain our results to stockholders and the investment community and in the internal evaluation and management of our business. We believe our non-GAAP financial measures provide management and investors with a more complete understanding of our underlying operational results and trends, facilitate meaningful period-to-period comparisons and enhance an overall understanding of our past and future financial performance.

Our non-GAAP financial measures exclude certain items that may have a material impact upon our reported financial results such as restructuring charges, the impact of foreign currency exchange rate fluctuations, unusual tax items, goodwill impairment charges, and other non-recurring items that we consider to be outside of our core operations. These measures should not be considered in isolation or as a substitute for, or superior to, the directly comparable GAAP financial measures and should be read in connection with the Company's financial statements presented in accordance with GAAP.

Our non-GAAP financial measures include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Adjusted Operating Income (Loss)/Adjusted Income (Loss) Before Taxes/Adjusted Net Income (Loss)/Adjusted Net Income (Loss) Per Diluted Share : Represents operating income (loss), income (loss) before taxes, net income (loss), and net income (loss) per diluted share excluding restructuring and goodwill and indefinite lived trade name impairment charges, the amortization of intangibles, non-recurring items, other income/expense, adjustments to reflect the estimated annual tax rate and discrete income tax adjustments, including income tax related to the foregoing. We believe these adjusted non-GAAP financial measures are useful to investors and management because they reflect our underlying operating performance before items that we consider to be outside our core operations and facilitate meaningful period-to-period comparisons. Senior management's incentive compensation is derived, in part, using adjusted operating income and adjusted net income per diluted share, which is derived from adjusted net income. We sometimes refer to adjusted net income per diluted share as adjusted earnings per share or adjusted EPS.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Free Cash Flow / Adjusted Free Cash Flow: Free cash flow represents cash flow from operating activities less cash used for additions to property, plant and equipment. Adjusted free cash flow is free cash flow plus proceeds from the disposition of assets. We believe free cash flow and adjusted free cash flow are useful to investors because it measures our available cash flow for paying dividends, reducing debt, repurchasing shares and funding acquisitions.
