Item 7.01. Regulation FD Disclosure.
On May 17, 2013, AmerisourceBergen Corporation (the "Company") issued a news release in which it reiterated its expectations for financial performance for fiscal year 2013, including expected revenue growth in the 11 percent to 13 percent range, and adjusted diluted earnings per share from continuing operations in the lower half of the range of $3.04 to $3.14, excluding certain expenses related to the relationship with Walgreen Co. ("Walgreens") and Alliance Boots GmbH ("Alliance Boots") and the warrants issued (as described below), and the expected LIFO charge from onboarding of additional branded inventory. The assumptions for fiscal 2013 adjusted diluted earnings per share from continuing operations stated in the Company's Current Report on Form 8-K filed on April 25, 2013 remain unchanged.
In addition, the Company announced that it continues to expect the Walgreens and Alliance Boots agreements (as described below) to contribute an incremental $25 billion in revenues and approximately 20 cents in adjusted earnings per share in fiscal 2014, excluding the amortization of certain expenses related to the transaction and the warrants issued, certain non-recurring costs and a potential LIFO charge, and net of certain start-up expenses.
A copy of the news release is being furnished as Exhibit 99.1 to this report and is incorporated herein by reference.
Item 8.01. Other Events.
In the news release issued on May 17, 2013, the Company announced that the parties have received regulatory approval of the previously disclosed agreement for Walgreens and Alliance Boots to purchase an equity stake in the Company. On March 19, 2013, the Company announced that it had entered into a strategic, long-term relationship with Walgreens and Alliance Boots, which includes: a ten-year comprehensive primary pharmaceutical distribution contract with Walgreens; access to generic drugs and related pharmaceutical products through the Walgreens Boots Alliance Development joint venture; and opportunities to accelerate the Company's efforts to grow its specialty and manufacturer services businesses domestically and internationally.
In furtherance of this new partnership, Walgreens and Alliance Boots together were granted rights to purchase an equity position in the Company, beginning with the right to purchase in the open market up to 7 percent of the fully diluted equity of the Company. In addition, the Company granted to Walgreens and Alliance Boots equity warrants exercisable for 16 percent in the aggregate of the fully diluted equity of the Company.  The first tranche of warrants, representing 8 percent of the fully diluted equity of the Company, has a strike price of $51.50 and will be exercisable for a six-month period beginning in March 2016.  The second tranche of warrants, also representing 8 percent of the fully diluted equity of the Company, has a strike price of $52.50 and will be exercisable for a six-month period beginning in March 2017.  The warrants were allocated equally among Walgreens and Alliance Boots.  Walgreens and Alliance Boots have agreed to customary transfer restrictions on their equity stake, and have also agreed not to acquire additional equity of the Company under the terms of a
2
standstill agreement, subject to the terms and conditions of such agreement, including certain pre-emption rights and permitted exceptions.
Walgreens will have the ability to appoint one director to the Company's board upon Walgreens and Alliance Boots together acquiring a 5 percent equity stake, and a second director upon exercise in full of the first tranche of warrants.
