Forward-Looking

Statements

Certain

statements contained in this release include “forward-looking statements” within the meaning of U.S. federal securities laws

and “forward-looking information” within the meaning of Canadian securities laws (collectively, "forward-looking statements").

Forward-looking statements herein include, in particular, statements relating to the anticipated

benefits of the acquisition, the anticipated impact of the acquisition on RB Global’s business and future financial and operating

results, expansion and other value creation opportunities from the acquisition, future operating plans relating to the acquisition,

and other subjects of this release that are not historical facts. Forward-looking statements are typically identified by such words as

“advance”, “aim”, “anticipate”, “believe”, “could”, “continue”,

“estimate”, “expect”, “intend”, “may”, “ongoing”, “plan”, “potential”,

“predict”, “will”, “should”, “would”, “could”, “likely”, “generally”,

“future”, “long-term”, or the negative of these terms, and similar expressions intended to identify forward-looking

statements. It is uncertain whether any of the events anticipated by the forward-looking statements will transpire or occur, or if any

of them do, what impact they will have on the results of operations and financial condition of RB Global's common shares. Therefore,

you should not place undue reliance on any such forward-looking statements and caution must be exercised in relying on forward-looking

statements. Forward-looking statements are based on current expectations and assumptions that are subject to risks and uncertainties

that may cause actual results to differ materially, including but not limited to risks and uncertainties relating to: our ability to

drive shareholder value; potential growth and market opportunities; the level of participation in our auctions and the success of our

online marketplaces; our ability to grow our businesses, acquire new customers, enhance our sector reach, drive geographic depth, and

scale our operations; the impact of our initiatives, services, investments, and acquisitions on us and our customers; the acquisition

or disposition of properties; potential future mergers and acquisitions; our ability to integrate acquisitions; our future capital expenditures

and returns on those expenditures; our ability to add new business and information solutions, including, among others, our ability to

maximize and integrate technology to enhance our existing services and support additional value-added service offerings; the supply trend

of equipment and vehicles in the market and the anticipated price environment, as well as the resulting effect on our business and Gross

Transaction Value (“GTV”); our compliance with laws, rules, regulations, and requirements that affect our business; effects

of various economic, financial, industry, and market conditions or policies, including inflation, the supply and demand for property,

equipment, or natural resources; the behavior of commercial assets and vehicle pricing; the relative percentage of GTV represented by

straight commission or underwritten (guarantee and inventory) contracts, and its impact on revenues and profitability; our future capital

expenditures and returns on those expenditures; the effect of any currency exchange and interest rate fluctuations on our results of

operations; the effect of any tariffs on our results of operations; the grant and satisfaction of equity awards pursuant to our compensation

plans; any future declaration and payment of dividends, including the tax treatment of any such dividends; financing available to us

from our credit facilities or other sources, our ability to refinance borrowings, and the sufficiency of our working capital to meet

our financial needs; our ability to satisfy our present operating requirements and fund future growth through existing working capital,

credit facilities and debt; misappropriation of data or cybersecurity incidents; and, failure to comply with privacy and data protection

laws. Other risks that could cause actual results to differ materially from those described in the forward-looking statements are included

in “Part I, Item 1A: Risk Factors”, and the section titled "Summary of Risk Factors", in our Annual Report

on Form 10-K for the year ended December 31, 2025, as such risk factors may be amended, supplemented or superseded from time

to time by other reports we file with the Securities and Exchange Commission, including subsequent Quarterly Reports on Form 10-Q

The forward-looking statements included in this release are made only as of the date hereof. While the list of factors presented here

is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties.

Many of these risk factors are outside of our control, and as such, they involve risks which are not currently known that could cause

actual results to differ materially from those discussed or implied herein. RB Global does not undertake any obligation to update any

forward-looking statements to reflect actual results, new information, future events, changes in its expectations or other circumstances

that exist after the date as of which the forward-looking statements were made, except as required by law.
