Walgreens Boots Alliance Exercises Second Tranche of Warrants to Purchase AmerisourceBergen Shares

DEERFIELD, Ill.–(BUSINESS WIRE)–Walgreens Boots Alliance, Inc. (Nasdaq: WBA) today announced that it had
agreed with AmerisourceBergen Corporation (NYSE: ABC) to amend the
second tranche of warrants held by Walgreens Boots Alliance to purchase
AmerisourceBergen common stock, so as to permit the immediate exercise
of these warrants. The warrants were originally scheduled to be
exercisable in March 2017.

Walgreens Boots Alliance then exercised these warrants and purchased
22,696,912 shares of AmerisourceBergen common stock for an aggregate
payment of approximately $1.19 billion. The transaction was funded using
existing cash on hand.

“Today’s announcement builds on the strong and collaborative working
relationship our companies have built together, and further strengthens
the long-term strategic relationship we launched in 2013,” said
Executive Vice Chairman and CEO Stefano Pessina. “Since the beginning of
the strategic relationship, we have worked together with
AmerisourceBergen to improve the customer experience by delivering the
right products at the right time to ensure that we are able to provide
exceptional patient access and care in our U.S. pharmacy operations.”

With today’s exercise of these warrants, Walgreens Boots Alliance now
beneficially owns 56,854,867 shares of AmerisourceBergen common stock,
or 23.9 percent of AmerisourceBergen’s outstanding equity (based on
shares outstanding as of 31 July 2016, adjusted to give effect to the
exercise of these warrants).

Walgreens Boots Alliance intends to continue to account for its
investment in AmerisourceBergen using the equity method of accounting,
subject to a two-month lag, with the net earnings attributable to its
investment being classified within the operating income of the company’s
