These Non GAAP financial measures are used by Shire's management to make operating decisions because they facilitate internal comparisons of the Company's performance to historical results and to competitors' results. These measures are also considered by Shire's Remuneration Committee in assessing the performance and compensation of employees, including its executive directors.

The Non GAAP measures are presented in this press release as the Company's management believe that they will provide investors with a means of evaluating, and an understanding of how Shire's management evaluates, the Company's performance and results on a comparable basis that is not otherwise apparent on a US GAAP basis, since many one-time, infrequent or non-cash items that the Company's management believe are not indicative of the core performance of the business may not be excluded when preparing financial measures under US GAAP.

These Non GAAP measures should not be considered in isolation from, as substitutes for, or superior to financial measures prepared in accordance with US GAAP.
