Proxy Statement

Notice of Annual and Special Meeting of

Shareholders to be held on April 30, 2026

Dear Fellow Shareholders,

We are proud of our strong financial and operating results in 2025 and the resulting returns we delivered to RB Global shareholders, including a 1% increase in Diluted Earnings Per Share. This strong performance, combined with continued confidence in our strategy, led to a ~14% increase in RB Global’s stock price for the year.

Our team’s commitment to our partners and customers, the operational excellence instilled across the organization, and disciplined investments in strategic growth areas paved the way for this meaningful upside. We believe we are well-positioned to capture market share in large and growing markets. We have robust cash flows to fuel both capital returns and value-creating investments that help extend our geographic reach, support our entry into complementary and adjacent end markets, strengthen our ecosystem, and accelerate access to new customers. RB Global’s Board of Directors and management team are confident in the road ahead and our ability to continue driving sustainable, long-term shareholder value.

Building on Our Significant Momentum

In the commercial construction and transportation sector, we are enhancing operational efficiency and advancing our growth strategy to help navigate a dynamic market environment and to support our ability to capitalize on emerging opportunities as market conditions evolve. We continue to optimize our territory manager network and implement targeted initiatives, which are designed to enhance our sales force’s productivity. In addition to acquisitions, we continue to invest in making our customers’ experience better, both digitally and physically at the yard.

In our automotive sector, we continued to outpace the market in 2025, achieving market-share gains and expanding unit volumes. Strong operational performance for our partners remained a hallmark, with service-level excellence and continued growth in average selling prices for our U.S. insurance partners. We also continued to grow our international buyer base with new market alliance partners and expanded our international partnerships, reinforcing our leadership position and setting the stage for continued growth.

Enhanced Operating Model – Increasing Speed and Driving Exceptional Customer Experiences

To best position the Company for the future, on August 12, 2025, we announced that we were realigning the executive leadership team and implementing a new, transformative operating model. Anchored by senior leaders who drive a culture of clarity, focus, and speed, the new structure empowers our teams to concentrate on what matters most – increasing transactional volumes and delivering exceptional customer experiences that drive tangible value for our partners.

We Look Forward to Sharing More About Our Progress with You

We look forward to discussing our progress and future value-creation opportunities over the coming year, as well as at the upcoming Annual and Special Meeting of Shareholders on April 30, 2026. Registered shareholders may participate in our annual meeting online via live webcast, as outlined in this proxy statement. Your vote is important to us, and we hope your shares are represented and voted at the meeting. Instructions on voting are found throughout this proxy statement, including in the section entitled “Questions and Answers About the Meeting, Proxy Materials and Voting.”
