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,” “anticipates” or “plans” to be uncertain and forward-looking.

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, 2019 as well as the Form 10-Q for the quarter ended March 31, 2020, expected to be filed with the SEC shortly after the date of this presentation, and also made available on Premier’s website at investors.premierinc.com.

Fiscal 2020 updated financial guidance * Fiscal 2020 Financial Guidance (in millions, except per share data) Current FY 2020 % YoY Increase Range Expectations Net Revenue:   Supply Chain Services segment $895.0 - $930.0 5% - 9% Higher end of range Performance Services segment $340.0 - $354.0 (6)% - (2)% Lower end of range Total Net Revenue $1,235.0 - $1,284.0 1% - 5% Higher end of range     Non-GAAP adjusted EBITDA $566.0 - $589.0 1% - 5% Lower end or slightly below range     Non-GAAP adjusted fully distributed EPS $2.76 - $2.89 4% - 9% Lower end or slightly below range * For the year ending June 30, 2020. As of May 5, 2020. See accompanying page for fiscal 2020 notes and assumptions to guidance.

Fiscal 2020 financial guidance footnotes and key assumptions * Guidance Footnotes: * The company does not meaningfully reconcile guidance for non-GAAP adjusted EBITDA and non-GAAP adjusted fully distributed earnings per share to net income attributable to stockholders or earnings per share attributable to stockholders because the company cannot provide guidance for more significant reconciling items between net income attributable to stockholders and adjusted EBITDA and between earnings per share attributable to stockholders and non-GAAP adjusted fully distributed earnings per share without unreasonable effort. This is due to two primary reasons: • Reasonable guidance cannot be provided for reconciling the adjustment of redeemable limited partners’ capital to redemption amount – historically the largest adjustment in the reconciliation from non-GAAP to GAAP amounts – due to the fact that the increase or decrease in this item is based on the change in the number of Class B common units outstanding and change in stock price between quarters, which the company cannot predict, control or reasonably estimate. • Reasonable guidance cannot be provided for earnings per share attributable to stockholders because the ongoing quarterly member-owner exchange of Class B common units and corresponding Class B common stock into shares of Class A common stock impacts the number of shares of Class A common stock outstanding each quarter, which the company cannot predict, control or reasonably estimate. Member owners have the right, but not the obligation, to exchange class B common units on a quarterly basis, and the company has the discretion to settle any exchanged units for Class A common stock, cash, or a combination thereof, neither of which can be predicted, controlled or reasonably estimated at this time. Key Assumptions*: Supply Chain Services assumptions: Net administrative fees revenue growth of 2% to 6% Products revenue growth of 20% to 30% Continued high GPO retention rates Performance Services assumptions: Continued high SaaS institutional renewal rates Continued challenge of hesitant demand in some areas, including quality and safety technology, and cost management and value-based care consulting related to political and regulatory uncertainty Extension of Hospital Improvement Innovation Network contract with CMS at rates approximately $6.0 million compared to $14.4 million generated in fiscal 2019 Other assumptions: Estimated revenue available under contract of approximately $1.1 billion, which represents approximately 88% to 93% of our consolidated net revenue guidance range Fiscal 2020 non-GAAP free cash flow will be impacted due to the implications of COVID-19 on fourth quarter net administrative fees revenue, as well as a result of the timing of cash inflows and outflows given strategic decision to use operating cash flow to procure necessary products in direct souring to address increased member demand for products; given the COVID-19 related surge in demand, Premier is unlikely to collect cash on product sales within the same quarter that the purchase of these products is funded Capital expenditures of $95 million to $100 million, representing 7% to 8% of consolidated net revenue Consolidated non-GAAP adjusted EBITDA margin of 44% to 48% Stock-based compensation of $28 million to $32 million Non-GAAP adjusted fully distributed net income and earnings per share calculations to reflect an effective tax rate of 26% Amortization of purchased intangible assets of approximately $50 million Guidance does not contemplate any future share repurchases or significant acquisitions *As of May 5, 2020.
