FORWARD-LOOKING STATEMENTS

This report contains information that may constitute “forward-looking statements.” Generally, the words “believe,” “expect,” “intend,” “estimate,” “anticipate,” “project,” “will,” “may” and similar expressions identify forward-looking statements, which generally are not historical in nature. All statements that address operating performance and events or developments that we expect or anticipate will occur in the future, including statements related to our strategy, our future operating results, improvements in our information technology and data security infrastructure, the expected financial and operational benefits, synergies and growth from our acquisitions, the expected benefits of our use of artificial intelligence, the pricing strategies, benefits and value proposition of product offerings of Equifax and its competitors, changes in the U.S. mortgage market environment (as well as changes more generally in U.S. and worldwide economic conditions), such as changes in interest rates and inflation levels, and similar statements about our financial outlook and business plans, are forward-looking statements. Management believes that these forward-looking statements are reasonable as and when made. However, forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from the Company’s historical experience and our present expectations or projections, including without limitation our expectations regarding the Company’s outlook, long-term organic and inorganic growth, and customer acceptance of our business solutions referenced below under “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Business Overview.” These risks and uncertainties include, but are not limited to, those described in Part II, “Item 1A. Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2025, and those described from time to time in our future reports filed with the United States Securities and Exchange Commission (“SEC”). As a result of such risks and uncertainties, we urge you not to place undue reliance on any such forward-looking statements. Forward-looking statements speak only as of the date when made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
