2025 Proxy Statement and Notice of Annual Meeting of Stockholders

A Letter from Our Chairman and Our CEO

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 20, 2025. The sole purpose of the meeting is to consider the matters described in the following Notice of 2025 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 2024, we were pleased with our strong execution on our strategic initiatives, despite a continued challenging demand back drop. Our proactive actions are yielding positive results and better position us for long-term growth.

We are dedicated to enhancing our revenue outcomes through both organic and inorganic strategies. By positioning key business leaders closer to our customers, we have strengthened customer relationships and unlocked additional growth opportunities. Furthermore, we have successfully expanded our distribution across various channels and categories. Our efforts have been refocused on innovation and new product development, and we remain committed to investing in our leading brands.

On the cost front, we delivered approximately $25 million in cost savings for the year from our $60 million multi-year cost reduction program. This program has simplified the organization, delayered our management structure and rationalized our global footprint through a reduction of our manufacturing facilities. Given continued economic uncertainty, we enhanced our $60 million multi-year cost reduction program, bringing the new total to $100 million.

Our proactive approach to cost management allowed us to deliver improved operating margins and cash flows for a second consecutive year. This improvement, and our commitment to debt reduction over the past two years, enables us to expand our capital allocation strategy to include share repurchases and potential M&A. We will continue to support our quarterly dividend and strengthen our balance sheet through debt reduction. As we continue to execute against our refined strategy, we are confident that the actions we are taking will drive long-term stockholder value.

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