(1) execute for and on behalf of the undersigned, in the undersigned's capacity as an officer
and/or director of Perrigo Company plc (the "Company"), Forms 3, 4 and 5 in accordance
with Section 16(a) of the Securities Exchange Act of 1934 and the rules thereunder;
(2) do and perform any and all acts for and on behalf of the undersigned that may be
necessary or desirable to complete and execute any such Form 3, 4, or 5, complete and
execute any amendment thereto, and timely file such form with the United States

The undersigned hereby grants to each such attorney-in-fact full power and authority to do any
