Forward-Looking Statements and Non-GAAP Financial Measures Forward-looking statements – Statements made in this presentation and the accompanying webcast that are not statements of historical or current facts, such as those related to our ability to advance our long-term strategies, our expected future business and financial performance, our ability to develop innovations that address the evolving healthcare and macro-economic trends in supply chain and staffing, our ability to develop new and improved solutions using technology and artificial intelligence that address the evolving needs of our member healthcare providers, the impact of our investments in adjacent markets businesses, our future organic growth and acquisition strategies, our expected effective income tax rate, the potential for future payment of dividends, our evaluation of strategic alternatives, and the potential for future share repurchase programs, are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of Premier to be materially different from historical results or from any future results or projections expressed or implied by such forward-looking statements. Accordingly, readers should not place undue reliance on any forward-looking statements. In addition to statements that explicitly describe such risks and uncertainties, readers are urged to consider statements in the conditional or future tenses or that include terms such as “believes,” “belief,” “expects,” “estimates,” “intends,” “remains committed to,” “anticipates” or “plans” to be uncertain and forward-looking. Forward-looking statements may include comments as to Premier’s beliefs and expectations as to future events and trends affecting its business and are necessarily subject to uncertainties, many of which are outside Premier’s control. More information on potential factors that could affect Premier’s financial results is included from time to time in the “Cautionary Note Regarding Forward-Looking Statements,” “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of Premier’s periodic and current filings with the SEC, including those discussed under the “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” section of Premier’s Form 10-K for the year ended June 30, 2023, as well as Premier’s Form 10-Q for the quarter ended September 30, 2023. Premier’s periodic and current filings with the SEC are available on the company’s website at investors.premierinc.com. Forward-looking statements speak only as of the date they are made, and Premier undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information or future events that occur after that date, or otherwise. Non-GAAP financial measures – During the webcast that accompanies this presentation, we may refer to certain “adjusted” and other “non-GAAP” financial measures as defined in Regulation G under the Securities Exchange Act of 1934. These measures are not in accordance with, or an alternative to, GAAP. You should carefully read Premier’s earnings releases and periodic and current filings with the SEC for reconciliations of our non-GAAP financial measures to the most directly comparable GAAP financial measures, definitions of our non-GAAP financial measures, and further explanation and disclosure regarding our use of non-GAAP financial measures and such information should be read in conjunction with this presentation. These materials are available on the company’s website at investors.premierinc.com.
