PREMIER, INC. REPORTS FISCAL 2015 FIRST-QUARTER RESULTS

CHARLOTTE, NC, November 10, 2014 – Premier, Inc. (NASDAQ: PINC) today reported financial results for the fiscal 2015 first quarter ended September 30, 2014.

Fiscal First-Quarter Highlights:

* Non-GAAP pro forma results reflect the impact of the company’s Reorganization and Initial Public Offering (IPO). Actual results prior to the company’s Reorganization and IPO consummated on October 1, 2013, do not reflect the impact of the Reorganization and IPO, and therefore, management believes they do not provide meaningful year-over-year comparisons. A description of adjusted EBITDA and other non-GAAP financial measures is provided in “Use and Definition of Non-GAAP Measures,” and reconciliations are provided in the tables at the end of this release. See “Reorganization and Initial Public Offering” for important information regarding non-GAAP pro forma results.

“We are pleased to report a strong start to fiscal 2015,” said Susan DeVore, president and chief executive officer. “Premier’s first-quarter financial performance exceeded our expectations for revenue and adjusted EBITDA growth. Based on our year-to-date execution and outlook for the remainder of the fiscal year, we are affirming our full-year financial guidance, which projects a consolidated net revenue increase of 11% to 14% over prior-year non-GAAP pro

forma results, a Supply Chain Services segment revenue increase of 8% to 11% over prior-year non-GAAP pro forma results, a Performance Services segment revenue increase of 21% to 24%, growth in adjusted EBITDA of 8% to 11% over prior-year non-GAAP pro forma results, and 7% to 11% growth in adjusted fully distributed earnings per share over prior-year non-GAAP pro forma results.

“During the quarter, we continued to win new business, grow market share and expand relationships with existing members, due to the depth and scope of our product and service offerings,” DeVore continued. “Supply Chain Services segment revenue grew as a result of increased utilization of our direct sourcing and specialty pharmacy businesses, as well as continued strength in net administrative fees revenue from our GPO (group purchasing organization). This was driven by new member conversions and higher utilization of our GPO contracts by existing acute and alternate-site members.

“The increase in Performance Services segment revenue resulted from across-the-board growth in SaaS-based informatics products, including PremierConnect^® Enterprise and population health, advisory services engagements, and performance improvement collaboratives,” DeVore said. “Our Aperek and TheraDoc acquisitions closed on August 29^th and September 1^st, respectively, and we are excited by the expanding growth opportunities and revenue contributions that we anticipate from these acquisitions as the year progresses.

“Premier’s proven ability to provide integrated, actionable intelligence across our supply chain, informatics and advisory services businesses delivers measurable solutions to the pressing cost, quality, safety and population health challenges facing healthcare providers today and as they prepare for the future,” DeVore added. “We believe this comprehensive approach is unique in the healthcare services market today, and is a testament to the leadership position that we continue to earn as we transform the way healthcare is delivered in our country. As we move forward, we intend to further expand and leverage these capabilities through our aligned delivery channel and collaborative member relationships, as we strive to provide continuous effective solutions to the marketplace and achieve continued profitable growth for our company and long-term performance for our shareholders.”

Results of Operations for the First Quarter of Fiscal 2015

Consolidated First-Quarter Financial Highlights

For the three months ended September 30, 2014, Premier generated net revenue of $229.3 million, an increase of $30.0 million, or 15%, from non-GAAP pro forma net revenue of $199.3 million for the same period a year ago. The revenue was comprised of $170.3 million in Supply Chain Services segment revenue and $59.0 million in Performance Services segment revenue.

Adjusted EBITDA for the fiscal first quarter totaled $90.5 million, an increase of $7.4 million, or 9%, from non-GAAP pro forma adjusted EBITDA of $83.1 million for the same period last year. Fiscal 2015 first-quarter adjusted EBITDA was fueled by revenue growth in both of the company’s business segments.

Adjusted fully distributed net income for the first quarter of fiscal 2015 rose to $47.8 million, or $0.33 per fully diluted share, from non-GAAP pro forma adjusted fully distributed net income of $45.1 million, or $0.31 per fully diluted share, for the same period a year ago. Adjusted fully distributed earnings per share is a non-GAAP measure that represents net income, adjusted for non-recurring and non-cash items, attributable to all shareholders as if all Class B shareholders have converted to Class A shareholders, and reflects income taxes at an estimated effective rate of approximately 40% on 100% of pretax income.

On a GAAP basis, net revenue was $229.3 million for the quarter ended September 30, 2014, compared with $240.6 million for the same period last year. Net income for the quarter totaled $64.9 million, compared with $112.5 million for the same quarter a year ago, and net income attributable to shareholders was $9.3 million, compared with a loss of $0.5 million for the same period a year ago. In accordance with GAAP, the per share net loss includes a non-cash negative adjustment of $382.7 million to GAAP net income attributable to shareholders to reflect redeemable limited partners’ capital at the appropriate redemption amount at the end of the period as a result of the benefit obtained by limited partners through the ownership of Class B common units. On a fully diluted per-share basis, the company reported a net loss of $11.53, compared with a net loss of $0.08 a year ago. (See income statement in the tables section of this press release.) Note: Comparisons of GAAP results are impacted by the changes associated with the Reorganization and IPO, as described below, and therefore, management believes they do not provide meaningful year-over-year comparisons.

Segment Results

Supply Chain Services

For the fiscal first quarter ended September 30, 2014, the Supply Chain Services segment generated net revenue of $170.3 million, an increase of $24.1 million, or 16%, from non-GAAP pro forma segment net revenue of $146.2 million a year ago. Revenue growth was driven by direct sourcing and specialty pharmacy revenues, which increased $19.9 million, or 45%, to $63.6 million, primarily from the ongoing expansion of member support for the company’s direct sourcing and specialty pharmacy businesses. GPO net administrative fees revenue of $106.5 million increased $4.2 million, or 4.1%, from non-GAAP pro forma results a year ago, reflecting the impact of new member conversion to the company’s contract portfolio, as well as growth from existing acute and alternate-site GPO members.

Supply Chain Services segment adjusted EBITDA of $91.3 million for the fiscal 2015 first quarter increased $7.1 million, or 8%, from non-GAAP pro forma segment adjusted EBITDA of $84.2 million for the same period a year ago. The increase largely reflects growth in net administrative fees revenue, as well as growth in the company’s direct sourcing activities, and continued effective management of operating expenses.

Supply Chain Services segment net revenue of $170.3 million for the fiscal 2015 first quarter compares with segment GAAP net revenue of $187.5 million for the same period a year ago. Segment adjusted EBITDA of $91.3 million compares with $125.5 million for the same period a year ago. Note: declines from the year-ago period are a function of the changes described with the non-GAAP pro forma results as a result of the company’s Reorganization and IPO, and management believes they do not provide meaningful year-over-year comparisons.

Performance Services

For the fiscal first quarter ended September 30, 2014, the Performance Services segment generated net revenue of $59.0 million, an increase of $5.9 million, or 11%, from $53.1 million for the same quarter last year. Revenue growth, which was consistent with management’s expectations, was due to increased sales and renewals of SaaS-based informatics product subscriptions, including the company’s PremierConnect Enterprise and population health offerings, as well as increased revenue from advisory services and performance improvement collaboratives. It also includes one month of contributions related to the acquisitions of Aperek and TheraDoc. Performance Services segment revenue growth can be impacted by potential quarterly variability related to timing of revenue recognition as a result of increased demand and growth in advisory services engagements.

Performance Services segment adjusted EBITDA was $18.4 million for the fiscal 2015 first quarter, an increase of approximately $2.0 million, or 12%, from $16.3 million for the same quarter last year. The increase in adjusted EBITDA reflects the same factors that contributed to revenue growth as well as the impact of investments in personnel to deliver anticipated growth for the remainder of the fiscal year. Note: Non-GAAP pro forma results do not impact the financial results for the company’s Performance Services segment.

Cash Flows and Liquidity

Cash provided by operating activities was $45.9 million for the fiscal first quarter ended September 30, 2014, a decrease of $20.9 million from $66.8 million for the same quarter a year ago. Operating cash flows decreased primarily due to lower net income related to the addition of member owner revenue share as a result of the Reorganization and IPO and the payment of annual employee incentive compensation following completion of the June fiscal year end. At

September 30, 2014, the company’s cash, cash equivalents, short- and long-term marketable securities totaled $398.2 million, compared with $132.9 million at September 30, 2013, and consisted of $94.5 million in cash and cash equivalents and $303.7 million in marketable securities with maturities ranging from three to 24 months.

At September 30, 2014, there was no outstanding balance on the company’s unsecured $750 million, five-year revolving credit facility.

Fiscal 2015 Outlook and Guidance

Based on Premier’s first-quarter performance, current outlook and visibility into the current revenue stream, Premier believes it is well positioned financially and operationally for fiscal 2015, and affirms its fiscal-year financial guidance, which was introduced on August 25, 2014.

Fiscal 2015 Financial Guidance ⁽¹⁾

Premier, Inc. affirms full-year fiscal 2015 financial guidance, as follows:

Guidance assumptions do not contemplate the impact of any potential future acquisitions. For fiscal 2015, Premier continues to expect capital expenditures of approximately $63.0 million and a consolidated EBITDA margin of approximately 40%.

Reorganization and Initial Public Offering

On October 1, 2013, Premier completed its IPO by issuing 32,374,751 shares of its Class A common stock, at a price of $27.00 per share, raising net proceeds of approximately $821.7 million, before expenses. In connection with the IPO, Premier completed the reorganization of the company on October 1, 2013, issuing 112.6 million shares of Class B common stock representing, at that time, 77.7% of the common stock outstanding, and corresponding Class B common units in Premier Healthcare Alliance, L.P. (Premier LP) to its member owners.

The company’s historical consolidated operating results do not reflect the Reorganization, the IPO and contemplated use of net proceeds from the IPO. Therefore, in addition to presenting the historical actual results, the company presents and discusses non-GAAP pro forma results, which reflect the impact of the company’s Reorganization and IPO and the contemplated use of net proceeds from the IPO, to provide a more comparable indication of future expectations.

The key non-GAAP pro forma adjustments include:

Further details of the Reorganization and non-GAAP pro forma adjustments are in Premier’s Form 10-K for the fiscal year ended June 30, 2014, filed with the Securities and Exchange Commission (SEC) on September 4, 2014, and accessible on the SEC’s website at www.sec.gov and in the investor relations section of Premier’s website at investors.premierinc.com.

Use and Definition of Non-GAAP Measures

Premier uses adjusted EBITDA, segment adjusted EBITDA and adjusted fully distributed net income to facilitate a comparison of the company’s operating performance on a consistent basis from period to period that, when viewed in combination with its results prepared in accordance with GAAP, provides a more complete understanding of factors and trends affecting the company’s business than GAAP measures alone. The company believes adjusted EBITDA and segment adjusted EBITDA assist its board of directors, management and investors in comparing the company’s operating performance on a consistent basis from period to period because they remove the impact of the company’s asset base (primarily depreciation and amortization) and items outside the control of management (taxes), as well as other non-cash (impairment of intangible assets and purchase accounting adjustments) and non-recurring items, from operations.

In addition, adjusted fully distributed net income eliminates the variability of non-controlling interest as a result of member owner exchanges of Class B common stock and corresponding Class B units into shares of Class A common stock (which exchanges are a member owner’s cumulative right, but not obligation, beginning on October 31, 2014, and each year thereafter, and are limited to one-seventh of the member owner’s initial allocation of Class B common units) and other potentially dilutive equity transactions which are outside of management’s control. Adjusted fully distributed net income is defined as net income attributable to PHSI (i) excluding income tax expense, (ii) excluding the effect of non-recurring and non-cash items, (iii) assuming the exchange of all the Class B common units for shares of Class A common stock, which results in the elimination of non-controlling interest in Premier LP, and (iv) reflecting an adjustment for income tax expense on non-GAAP pro forma fully distributed net income before income taxes at the company’s estimated effective income tax rate.

EBITDA is defined as net income before interest and investment income, net, income tax expense, depreciation and amortization and amortization of purchased intangible assets. Adjusted EBITDA is defined as EBITDA before merger and acquisition related expenses and non-recurring, non-cash or non-operating items, and including equity in net income of unconsolidated affiliates. Non-recurring items include certain strategic and financial restructuring expenses. Non-operating items include gain or loss on disposal of assets. Segment adjusted EBITDA is defined as the segment’s net revenue less operating expenses directly attributable to the segment, excluding depreciation and amortization, amortization of purchased intangible assets, merger and acquisition related expenses and non-recurring or non-cash items, and including equity in net income of unconsolidated affiliates. Operating expenses directly attributable to the segment include expenses associated with sales and marketing, general and administrative and product development activities specific to the operation of each segment. General and administrative corporate expenses that are not specific to a particular segment are not included in the calculation of segment adjusted EBITDA. Adjusted EBITDA is a supplemental financial measure used by the company and by external users of the company’s financial statements.

Management considers adjusted EBITDA an indicator of the operational strength and performance of the company’s business. Adjusted EBITDA allows management to assess performance without regard to financing methods and capital structure and without the impact of other matters that management does not consider indicative of the operating performance of the business. Segment adjusted EBITDA is the primary earnings measure used by management to evaluate the performance of the company’s business segments.
