Corporate Governance

The Role of the Board

The Board of Directors (the "Board") acts as the steward of the Company for the benefit of the shareholders. The Directors have a wealth of business experience and a solid track record in situations relevant to the Company's strategy and operations.

The Board recognizes the importance of ensuring that our strategy is designed and executed to create sustainable long-term value for Grainger's shareholders and other stakeholders. The Board plays an active role in formulating strategy and overseeing its implementation as to business, operational, financial and regulatory.

The Board has a robust annual strategic planning process during which key elements of our business, financial plans, strategies, and near-term and long-term initiatives are explained and reviewed. This process includes extended Board sessions with our senior leadership team to review Grainger's overall strategy, talent, opportunities, capabilities, as well as risks and challenges. In addition to business strategy, the Board reviews Grainger's short-term and long-term financial plans, which serve as the basis for the operating and capital plans for the upcoming year. The annual strategy process also helps shape the strategic content presented in our communications with the investment community. In addition to annual strategic reviews, the Board works with appropriate members of the Company's management team, who in turn consult with external advisors on at least a biennial basis to identify and prioritize key risks to the Company based on factors such as materiality and timeline implications. Further, the Board's continuous evaluation of the Company's strategic progress and risk oversight enables it to identify new opportunities and emerging risks with respect to our strategy and plans throughout the year.

Through its Committees (as defined herein), the Board oversees Grainger's approach to environmental, social and governance matters ("ESG"). In addition, at least annually, management briefs the entire Board on the Company's progress in executing its environmental, social and governance strategy.

The Board closely monitors and helps ensure that Grainger's management processes and financial resources have been effectively deployed to fulfill our purpose-We Keep the World Working®-and to remain the go-to-partner for people who build and run safe, sustainable, and productive operations. In 2025, the Company will focus on the following four priorities as we aim to continue serving our customers' maintenance, repair and operating ("MRO") needs better than anyone else, grow market share profitably and make Grainger a great place to work:

Board Actions

The Board believes that a diverse, experienced, and vibrant board significantly contributes to the broad-based thinking needed to reach sound decisions. These attributes equip the Board to oversee the Company in meeting both current challenges and future needs, and ultimately assist in driving shareholder value. The 2025 Board slate consists of 12 Director nominees with various experiences and backgrounds, including six non-employee Directors who have joined the Board since 2020. The addition of these Directors demonstrates the Board's commitment to gaining the benefits of broad perspectives and backgrounds.

The Board's various experiences and viewpoints benefit the Company most when they are aligned with our global business needs, reflective of our strong corporate governance practices, and consistent with our goals. As a result of the Board's ongoing refreshment efforts, we have added Directors with expertise in technology, digital commerce, finance and corporate transactions, workforce diversification and global logistics management. Our six newest non-employee Directors-George S. Davis, Katherine D. Jaspon, Christopher J. Klein, Cindy J. Miller, Susan Slavik Williams and Steven A. White-bring valuable perspectives and experiences to enhance the composition of our Board.

Corporate Culture: The Grainger Edge®

The Board strongly believes that the Company's culture must be tightly aligned with its business strategy to create value. To that end, the Board is actively engaged with senior management in cultivating Grainger's culture. The Board believes that the Company's purpose-driven culture is an asset that creates a sustainable competitive advantage. Building on the Company's strong foundation while evolving a framework to address future challenges is critical to Grainger's continued success.

In 2019, the Company introduced the Grainger Edge, a strategic framework that defines the Grainger culture, including the Company's purpose, aspiration and how team members work together to achieve Grainger's strategy.

The Grainger Edge includes a set of principles that defines the behaviors expected from team members as they work with each other, customers and suppliers. As highlighted on the inside of this proxy statement's cover page, the Grainger Edge principles are:

Start with the customer

Complete with urgency

Act with intent

• Invest in our success

Win as one team

Do the right thing

Embrace curiosity

The Grainger Edge principles support the Company's commitment to building a culture where all team members operate under the highest ethical standards both inside and outside of the Company. The Board fully endorses these principles and believes that alignment to them creates value for shareholders.

The Grainger Edge also is foundational to the Company's customer-focused business strategy. This strategy aims to consistently gain share through two distinct business models, positioning Grainger to leverage its scale and supply chain to support customers with a variety of needs.

The Company aligns its pay for performance compensation philosophy with the Grainger Edge to help further the Company's strategy and long-term value creation. Since 2023, the Company has been providing its Pay Versus Performance Disclosure reflecting compensation paid to its principal executive officers. See Pay Versus Performance Disclosure beginning on page 69.

The Board is actively engaged in making the Grainger Edge a successful foundational framework for the Company and its employees in an effort to consistently serve customers and gain share. The Board understands that top talent is necessary to achieve these goals and supports the Company's commitment to providing employees with resources designed to help them succeed. The Company's culture and principles advance the Board's role of ensuring that the Company attracts, retains, motivates and develops top talent across the Company. The Board routinely conducts in-depth reviews of senior leaders and their development. This engagement gives the Board insight into the Company's talent and succession plans.

The Board believes a culture of legal and ethical behavior is essential to positioning the Company to achieve its goals. Our Business Conduct Guidelines apply to all Directors, officers, and team members and were updated in February 2024. Grainger team members are required to complete Business Conduct Guidelines training and certification.

Delivering business results and creating a sustainable business that does the right thing has guided the Company for nearly 100 years. The continuing commitment to these objectives is illustrated by the Company's environmental, social and governance initiatives. The Board believes that a thoughtful approach aligned to our business can help build resilient processes, better serve customers and positively impact our team members, communities and the environment. These benefits have positioned us to build a sustainable end-to-end supply chain to continue to serve our customers well. See Environmental, Social and Governance (ESG) beginning on page 26.

Collectively, the activities of the Board and its Committees in reviewing strategy, ESG initiatives, culture, talent and ethical behavior enable the Company to help millions of customers worldwide keep their operations running and their people safe.
