Guidance Update

Dublin, Ireland - January 14, 2014 - Shire plc (LSE: SHP, NASDAQ: SHPG)

Dr. Flemming Ornskov, Chief Executive Officer of Shire, will address investors
today, Tuesday, January 14, 2014, at the JP Morgan Healthcare Conference in San
Francisco. In his address he will confirm that Shire finished 2013 strongly,
having successfully performed a strategy shift and introduced greater
operational discipline. Shire now expects to deliver Non GAAP EPS growth at the
upper end of the mid-to-high teens guidance range that was given at its Q3 2013
results (October 24, 2013).

As we look forward, Shire remains confident of delivering Non GAAP EPS for 2014
in line with the November 2013 consensus forecast(1) (excluding ViroPharma).
Shire will update its 2014 guidance during the Q4 2013 earnings call on
February 13, 2014. During this call Shire will also outline the accretive
benefits of the ViroPharma acquisition, if the deal has closed at that point.

Flemming's presentation will be webcast live today, Tuesday, January 14, 2014
at 07:30 am Pacific Time (15:30 GMT).

    and is reliant upon third party contractors for certain goods and services,
