FISCAL 2018 SECOND QUARTER RESULTS

Revenues of $41.0 Billion for the Second Quarter, a 10.5 Percent Increase Year-Over-Year

Second Quarter GAAP Diluted EPS of $1.29 and Adjusted Diluted EPS of $1.94

Adjusted Diluted EPS Guidance Maintained at $6.45 to $6.65 for Fiscal 2018; Company Expects to be at Bottom of Range

VALLEY FORGE, PA, May 2, 2018 - AmerisourceBergen Corporation (NYSE:ABC) today reported that in its fiscal year 2018 second quarter ended March 31, 2018, revenue increased 10.5 percent to $41.0 billion. On the basis of U.S. generally accepted accounting principles (GAAP), diluted earnings per share (EPS) was $1.29 for the March quarter of fiscal 2018, compared to $1.86 in the prior year quarter. Adjusted diluted EPS, which is a non-GAAP measure that excludes items described below, increased 9.6 percent to $1.94 in the fiscal second quarter.

AmerisourceBergen now believes adjusted diluted EPS for fiscal year 2018 will be at the bottom of its guidance range of $6.45 to $6.65, reflecting growth of 10 percent versus last fiscal year. The Company does not provide forward-looking guidance on a GAAP basis, as discussed below in Fiscal Year 2018 Expectations.

“I am pleased with our performance in the March quarter as associates and businesses within AmerisourceBergen continue to execute. Our distribution businesses are creating significant value for our customers as we grow volumes and help support their businesses in a dynamic healthcare market,” said Steven H. Collis, Chairman, President and Chief Executive Officer of AmerisourceBergen.

“Our updated outlook for fiscal 2018 reflects the strong performance of our Pharmaceutical Distribution Services segment, helping to offset a lower contribution from its PharMEDium business. We remain confident in the value, efficiency and safety PharMEDium provides the healthcare system and are committed to providing our customers with the highest quality products and services,” Mr. Collis continued. “As we move further into fiscal 2018, we are excited to begin realizing the benefits of investments throughout AmerisourceBergen that further enhance the value and efficiency we offer to our provider customers and manufacturer partners. Our long-term relationships and unique portfolio of integrated pharmaceutical services enable AmerisourceBergen to continue living its purpose as we are united in our responsibility to create healthier futures.”

In conjunction with incremental investments made in the second quarter of fiscal 2018 relating to Profarma and the specialty joint venture in Brazil, AmerisourceBergen began consolidating their operating results. Below, AmerisourceBergen presents descriptive summaries of the Company’s GAAP quarterly results as well as its adjusted (Non-GAAP) quarterly results. In the tables that follow, GAAP results and GAAP to Non-GAAP reconciliations are presented. For more information related to Non-GAAP financial measures, including our fiscal year 2018 expectations, please refer to the Supplemental Information Regarding Non-GAAP Financial Measures following the tables.

Second Quarter GAAP Results


•	Revenue: In the second quarter of fiscal 2018, revenue was $41.0 billion, up 10.5 percent compared to the same quarter in the previous fiscal year, reflecting a 10.4 percent increase in Pharmaceutical Distribution Services revenue and a 12.6 percent increase in revenue within Other.

•

Gross Profit: Gross profit in the fiscal 2018 second quarter was $1.3 billion, relatively flat compared to the same period in the previous fiscal year, due to the negative impact of PharMEDium's lower revenues and its facility remediation costs in the current year quarter and a LIFO credit that benefited the previous year period. There was no LIFO expense or credit in the fiscal 2018 second quarter. Gross profit as a percentage of revenue was 3.06 percent, a decrease of 32 basis points from the prior year quarter.

•

Operating Expenses: In the second quarter of fiscal 2018, operating expenses were $774.3 million, compared to $631.4 million in the same period last fiscal year. The increase in operating expenses was primarily driven by the acquisition of H. D. Smith, consolidation of Profarma and the specialty joint venture in Brazil, operating additional distribution centers in the current year quarter and duplicate costs resulting from the implementation of new information technology systems, as well as increased costs to support our revenue growth.


•	Operating Income: In the fiscal 2018 second quarter, operating income was $481.4 million versus $625.0 million in the prior year period.


•	Other Loss (Income): In the fiscal 2018 second quarter, other loss included a $30.0 million impairment on a non-customer note receivable related to a start-up venture.


•	Interest Expense, Net: In the fiscal 2018 second quarter, net interest expense of $48.6 million was up 30.4 percent versus the prior year quarter, primarily due to the new debt issued to finance the H. D. Smith acquisition.


•	Loss on Consolidation of Equity Investments: In the fiscal 2018 second quarter, a loss of $42.3 million was incurred primarily relating to the recognition of unrealized foreign currency translation losses in connection with the remeasurement of equity interests in Profarma and the specialty joint venture in Brazil.


•	Tax Rate: The effective tax rate of 21.9 percent for the second quarter of fiscal 2018 primarily reflects the reduction in the U.S. federal income tax rate from 35% to 21% and the benefit from stock option exercises.


•	Diluted Earnings Per Share: Diluted earnings per share was $1.29 in the second quarter of fiscal 2018 compared to $1.86 in the previous fiscal year’s second quarter.


•	Diluted Shares Outstanding: Diluted weighted average shares outstanding for the second quarter of fiscal 2018 were 222.3 million, a 0.5 percent increase versus the prior fiscal year second quarter, due primarily to stock option exercises, net of share repurchases.

Second Quarter Adjusted (Non-GAAP) Results


•	Revenue: In the second quarter of fiscal 2018, revenue was $41.0 billion, up 10.5 percent compared to the same quarter in the previous fiscal year, reflecting a 10.4 percent increase in Pharmaceutical Distribution Services revenue and a 12.6 percent increase in revenue within Other.

•

Adjusted Gross Profit: Gross profit in the fiscal 2018 second quarter was $1.3 billion, which was up 9.2 percent when compared to the same period in the previous year, primarily due to the increase in gross profit in Pharmaceutical Distribution Services, which includes the acquisition of H. D. Smith and the consolidation of Profarma. Gross profit as a percentage of revenue was 3.11 percent, a decrease of 4 basis points from the prior year quarter.

•

Adjusted Operating Expenses: In the second quarter of fiscal 2018, operating expenses were $691.5 million, an increase of 18.9% compared to the same period in the last fiscal year. Operating expenses as a percentage of revenue in the fiscal 2018 second quarter were 1.69 percent, compared to 1.57 percent for the same period in the previous fiscal year. The increase in operating expenses was driven by the acquisition of H. D. Smith, consolidation of Profarma and the specialty joint venture in Brazil, operating additional distribution centers in the current year quarter and duplicate costs resulting from the implementation of new information technology systems, as well as increased costs to support our revenue growth.


•	Adjusted Operating Income: In the fiscal 2018 second quarter, operating income of $586.3 million decreased 0.4 percent from the prior year period. Operating income as a percentage of revenue decreased 15 basis points to 1.43 percent in the fiscal 2018 second quarter compared to the previous fiscal year’s second quarter.

•	Adjusted Tax Rate: The effective tax rate for the second quarter of fiscal 2018 was 20.7 percent, down from 30.1 percent in the previous fiscal year’s second quarter, primarily driven by a reduction in the U.S. federal income tax rate from 35% to 21%.


•	Adjusted Diluted Earnings Per Share: Diluted earnings per share was up 9.6 percent to $1.94 in the second quarter of fiscal 2018 compared to $1.77 in the previous fiscal year’s second quarter, driven by the benefit from U.S. tax reform.


•	Diluted Shares Outstanding: Diluted weighted average shares outstanding for the second quarter of fiscal 2018 were 222.3 million, a 0.5 percent increase versus the prior fiscal year second quarter due primarily to stock option exercises, net of share repurchases.

Segment Discussion

The Company's operations are comprised of the Pharmaceutical Distribution Services reportable segment and other operating segments that are not significant enough to require separate reportable segment disclosure and, therefore, have been included in Other for the purpose of reportable segment presentation. Other consists of operating segments that focus on global

commercialization services and animal health and includes AmerisourceBergen Consulting Services (ABCS), World Courier and MWI Animal Health (MWI).

Pharmaceutical Distribution Services Segment

Pharmaceutical Distribution Services revenue was $39.5 billion, an increase of 10.4 percent compared to the same quarter in the prior fiscal year. Segment operating income of $489.1 million in the March quarter of fiscal 2018 was up 0.9 percent compared to the same period in the previous fiscal year, primarily due to growth in revenues and gross profit, including the acquisition of H. D. Smith, largely offset by reduced sales at PharMEDium and the operating loss at Profarma.

Other

Revenue in Other was $1.6 billion in the second quarter of fiscal 2018, an increase of 12.6 percent compared to the same period in the prior fiscal year, primarily due to the consolidation of the specialty joint venture in Brazil and revenue growth from MWI, ABCS's growth in its Canadian operations and World Courier. Operating income in Other decreased 6.3 percent to $97.1 million in the second quarter of fiscal 2018. This decrease was primarily driven by performance at ABCS, specifically the Lash Group, and was partially offset by increased contributions from World Courier and MWI.

Fiscal Year 2018 Expectations

The Company does not provide forward-looking guidance on a GAAP basis as certain financial information, the probable significance of which cannot be determined, is not available and cannot be reasonably estimated. Please refer to the Supplemental Information Regarding Non-GAAP Financial Measures following the tables for additional information.

Fiscal Year 2018 Expectations on an Adjusted (Non-GAAP) Basis

Based upon the Company’s performance in the first half of the fiscal year, evaluation of current business expectations and lower than previously anticipated operating income contributions from PharMEDium and the Lash Group, AmerisourceBergen has updated its fiscal year 2018 financial guidance. The higher operating expense growth expectation reflects the Company's current assumption that the PharMEDium remediation costs should be excluded from cost of goods sold instead of operating expenses. The Company expects:


•	Revenue growth in the range of 8 percent to 11 percent; and


•	Adjusted diluted earnings per share in the range of $6.45 to $6.65.

Additional expectations now include:


•	Adjusted operating expenses to increase between 8 percent to 10 percent;


•	Adjusted operating income growth to be flat;


•	Pharmaceutical Distribution Services segment operating income growth to be flat;


•	Other, which is comprised of businesses focused on Global Commercialization Services and Animal Health, operating income decline in the range of down 2 percent to 4 percent;


•	Adjusted effective tax rate of between 22 percent and 23 percent;


•	Adjusted free cash flow to be approximately $1.35 billion to $1.6 billion;


•	Capital expenditures of approximately $325 million; and


•	Share repurchases will offset dilution from employee stock option exercises.

AmerisourceBergen also continues to operate under the following working assumptions regarding the pharmaceutical market:


•	Brand drug inflation to be in the range of 6 percent to 7 percent;


•	Generic drug deflation to be in the range of -7 percent to -9 percent;


•	Contributions from new generic launches similar to the prior year; and


•	No significant contributions from biosimilars.

SUPPLEMENTAL INFORMATION REGARDING

NON-GAAP FINANCIAL MEASURES

To supplement the financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), the Company uses the following non-GAAP financial measures: (i) adjusted gross profit; (ii) adjusted operating expenses; (iii) adjusted operating income; (iv) adjusted interest expense, net; (v) adjusted tax rate; (vi) adjusted net income attributable to ABC; and (vii) adjusted diluted earnings per share. The non-GAAP financial measures should be viewed in addition to, and not in lieu of, financial measures calculated in accordance with GAAP. These supplemental measures may vary from, and may not be comparable to, similarly titled measures by other companies.

The non-GAAP financial measures are presented because management uses non-GAAP financial measures to evaluate the Company’s operating performance, to perform financial planning, and to determine incentive compensation. Therefore, the Company believes that the presentation of non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors. The presented non-GAAP financial measures exclude items that management does not believe reflect the Company’s core operating performance as such items are outside the control of the Company or due to their inherent unusual, non-operating, unpredictable, non-recurring, or non-cash nature. We have included the following non-GAAP earnings-related financial measures in this release:

•

Adjusted gross profit and adjusted gross profit margin: Adjusted gross profit is a non-GAAP financial measure that excludes the gain from antitrust litigation settlements, PharMEDium remediation costs, and LIFO expense (credit). Gain from antitrust litigation settlements and LIFO expense (credit) are excluded because the Company cannot control the amounts recognized or timing of these items. PharMEDium remediation costs are excluded because they are unpredictable and non-recurring expenses. Adjusted gross profit margin is the ratio of adjusted gross profit to total revenue. Management believes that these non-GAAP financial measures are useful to investors as a supplemental measure of the Company’s ongoing operating performance. The gain from antitrust litigation settlements relates to the settlement of class action lawsuits that have been filed against brand pharmaceutical manufacturers alleging that the manufacturer, by itself or in concert with others, took improper actions to delay or prevent generic drugs from entering the market. The PharMEDium remediation costs relate to costs incurred in connection with suspended production activities following U.S. Food and Drug Administration inspections. LIFO expense (credit) is affected by changes in inventory quantities, product mix, and manufacturer pricing practices, which may be impacted by market and other external influences.

•

Adjusted operating expenses and adjusted operating expense margin: Adjusted operating expenses is a non-GAAP financial measure that excludes acquisition-related intangibles amortization and employee severance, litigation, and other. Adjusted operating expense margin is the ratio of adjusted operating expenses to total revenue. The acquisition-related intangibles amortization is excluded because it is a non-cash item and does not reflect the operating performance of the acquired companies. We exclude employee severance amounts that relate to unpredictable and/or non-recurring business restructuring. We exclude the amount of litigation settlements and other expenses that are unusual, non-operating, unpredictable, non-recurring or non-cash in nature because we believe these exclusions facilitate the analysis of our ongoing operational performance.

•

Adjusted operating income and adjusted operating income margin: Adjusted operating income is a non-GAAP financial measure that excludes the same items that are described above and excluded from adjusted gross profit and adjusted operating expenses. Adjusted operating income margin is the ratio of adjusted operating income to total revenue. Management believes that these non-GAAP financial measures are useful to investors as a supplemental way to evaluate the Company’s performance because the adjustments are unusual, non-operating, unpredictable, non-recurring or non-cash in nature.

•

Adjusted interest expense, net: Adjusted interest expense is a non-GAAP financial measure that excludes the interest expense on our $600 million of 1.15% senior notes that were repaid in May 2017 (the “2017 Notes”). The 2017 Notes were issued to fund a special $650 million share repurchase program under which we purchased shares to reduce the dilution related to the warrants that we issued in March 2013 to wholly-owned subsidiaries of Walgreens Boots Alliance, Inc. Management believes that this non-GAAP financial measure is useful to investors in evaluating the Company’s ongoing interest expense, net.


•	Adjusted tax rate: Adjusted tax rate is a non-GAAP financial measure that is determined by dividing adjusted income tax expense/benefit by adjusted income before income taxes.

•

Adjusted net income attributable to ABC: Adjusted net income attributable to ABC is a non-GAAP financial measure that excludes the same items that are described above and excluded from adjusted gross profit, adjusted operating expenses, adjusted operating income, and adjusted interest expense, net. In addition, the loss on consolidation of equity investments, impairment on a non-customer note receivable, the loss on the early retirement of debt and the one-time impact of U.S. tax reform ("Tax Reform") are excluded from adjusted net income attributable to ABC. Tax Reform includes a benefit from

applying a lower U.S. federal income tax rate to the Company's net deferred tax liabilities as of December 31, 2017, offset in part by a one-time transition tax on historical foreign earnings and profits through December 31, 2017. Management believes that this non-GAAP financial measure is useful to investors as a supplemental way to evaluate the Company's performance because the adjustments are unusual, non-operating, unpredictable, non-recurring or non-cash in nature.

•

Adjusted diluted earnings per share: Adjusted diluted earnings per share excludes the per share impact of adjustments including gain from antitrust litigation settlements; LIFO expense (credit); PharMEDium remediation costs; acquisition-related intangibles amortization; employee severance, litigation, and other; loss on consolidation of equity investments; impairment on a non-customer note receivable; the interest expense incurred in connection with the 2017 Notes; and the loss on early retirement of debt; in each case net of the tax effect calculated using the applicable effective tax rate for those items. In addition, the per share impact of Tax Reform is excluded from adjusted diluted earnings per share. Management believes that this non-GAAP financial measure is useful to investors because it eliminates the per share impact of the items that are outside the control of the Company or that we consider to not be indicative of our ongoing operating performance due to their inherent unusual, non-operating, unpredictable, non-recurring, or non-cash nature.

In addition, the Company has provided non-GAAP fiscal year 2018 guidance for diluted earnings per share, operating expense, operating income, and effective income tax rate that excludes the same or similar items as those that are excluded from the historical non-GAAP financial measures, as well as significant items that are outside the control of the Company or inherently unusual, non-operating, unpredictable, non-recurring or non-cash in nature. In addition, it has provided 2018 free cash flow guidance. For fiscal year 2018, we have defined the non-GAAP financial measure of free cash flow as net cash provided by operating activities, excluding other significant unpredictable or non-recurring cash payments or receipts relating to legal settlements, minus capital expenditures. The Company does not provide forward looking guidance on a GAAP basis for such metrics because certain financial information, the probable significance of which cannot be determined, is not available and cannot be reasonably estimated. For example, LIFO expense (credit) is largely dependent upon the future inflation or deflation of brand and generic pharmaceuticals, which is out of the Company’s control, and acquisition-related intangibles amortization depends on the timing and amount of future acquisitions, which cannot be reasonably estimated. Similarly, the timing and amount of litigation settlements is unpredictable and non-recurring.
