Allergan Comments on ISS and Glass Lewis Recommendations

Allergan, Inc. (AGN) (“Allergan” or the “Company”) today issued the following statement regarding reports by Institutional Shareholder Services (“ISS”) and Glass Lewis on Pershing Square Capital Management, L.P’s (“Pershing Square”) solicitation to call a special meeting of Allergan’s stockholders (the “Special Meeting”).

These recommendations do not change the fact that Valeant’s offer is grossly inadequate, substantially undervalues Allergan, creates significant risks and uncertainties for Allergan stockholders and is not in the best interests of the Company and its stockholders. These reports merely state that ISS and Glass Lewis believe stockholders should have the right to call a special meeting in accordance with the provisions of the Company’s charter that were approved by Allergan’s Board of Directors and adopted by its stockholders in 2013 and the corresponding provisions of the Company’s bylaws.

Glass Lewis made it clear that they were not opining on the value or merit of Valeant’s proposal. In its report, Glass Lewis stated, “…we note the current process – as presently framed – does not represent a vote on the merits of any prospective combination transaction or any change to the sitting board; rather investors would only be participating in a process intended to afford them the opportunity to directly express their opinions – positive or negative – on those issues.”1 ISS notes “Shareholders cannot, through this consent solicitation, take any direct action to accept or reject the Valeant offer.” 1

Allergan recognizes that what matters to stockholders is value, and Allergan’s Board of Directors and management team remain focused on delivering significantly more value than Valeant’s proposal. Allergan’s recently announced second quarter results demonstrate continued, significant business momentum, with the Company once again delivering sales and earnings per share growth above the high end of its guidance and analyst estimates. Furthermore, Allergan’s value creation plan for its stockholders will significantly reduce costs in 2015 by approximately $475 million annually relative to its prior strategic plan, while preserving the Company’s ability to deliver double digit sales growth across the next five years. Over the same five year period, Allergan expects to generate compounded annual EPS growth of more than 20 percent.

Goldman, Sachs & Co. and BofA Merrill Lynch are serving as financial advisors to the Company and Latham & Watkins, Richards, Layton & Finger, P.A. and Wachtell, Lipton, Rosen & Katz are serving as legal counsel to the Company.
