2 “Safe Harbor” Statement Under The Private Securities Litigation Reform Act Of 1995 Statements included herein that are not historical facts, including without limitation statements concerning future strategy, plans, objectives, expectations and intentions, projected revenues, the anticipated timing of clinical trials and approvals for, and the commercial potential of, inline or pipeline products, are forward - looking statements. Such forward - looking statements involve a number of risks and uncertainties and are subject to change at any time. In the event such risks or uncertainties materialize, Shire’s results could be materially adversely affected. The risks and uncertainties include, but are not limited to, the following: • Shire’s products may not be a commercial success; • increased pricing pressures and limits on patient access as a result of governmental regulations and market developments may affect Shire’s future revenues, financial condition and results of operations; • Shire conducts its own manufacturing operations for certain of its products and is reliant on third party contract manufacturers to manufacture other products and to provide goods and services. Some of Shire’s products or ingredients are only available from a single approved source for manufacture. Any disruption to the supply chain for any of Shire’s products may result in Shire being unable to continue marketing or developing a product or may result in Shire being unable to do so on a commercially viable basis for some period of time; • the manufacture of Shire’s products is subject to extensive oversight by various regulatory agencies. Regulatory approvals or interventions associated with changes to manufacturing sites, ingredients or manufacturing processes could lead to, among other things, significant delays, an increase in operating costs, lost product sales, an interruption of research activities or the delay of new product launches; • certain of Shire’s therapies involve lengthy and complex processes, which may prevent Shire from timely responding to market forces and effectively managing its production capacity; • Shire has a portfolio of products in various stages of research and development. The successful development of these products is highly uncertain and requires significant expenditures and time, and there is no guarantee that these products will receive regulatory approval; • the actions of certain customers could affect Shire’s ability to sell or market products profitably. Fluctuations in buying or distribution patterns by such customers can adversely affect Shire’s revenues, financial conditions or results of operations; • Shire’s products and product candidates face substantial competition in the product markets in which it operates, including competition from generics; • adverse outcomes in legal matters, tax audits and other disputes, including Shire’s ability to enforce and defend patents and other intellectual property rights required for its business, could have a material adverse effect on the Company’s revenues, financial condition or results of operations; • inability to successfully compete for highly qualified personnel from other companies and organizations; • failure to achieve the strategic objectives, including expected operating efficiencies, cost savings, revenue enhancements, synergies or other benefits at the time anticipated or at all with respect to Shire’s acquisitions, including NPS Pharmaceuticals Inc., Dyax Corp. or Baxalta Incorporated may adversely affect Shire’s financial condition and results of operations; • Shire’s growth strategy depends in part upon its ability to expand its product portfolio through external collaborations, which, if unsuccessful, may adversely affect the development and sale of its products; • a slowdown of global economic growth, or economic instability of countries in which Shire does business, as well as changes in foreign currency exchange rates and interest rates, that adversely impact the availability and cost of credit and customer purchasing and payment patterns, including the collectability of customer accounts receivable; • failure of a marketed product to work effectively or if such a product is the cause of adverse side effects could result in damage to Shire’s reputation, the withdrawal of the product and legal action against Shire; • investigations or enforcement action by regulatory authorities or law enforcement agencies relating to Shire’s activities in the highly regulated markets in which it operates may result in significant legal costs and the payment of substantial compensation or fines; • Shire is dependent on information technology and its systems and infrastructure face certain risks, including from service disruptions, the loss of sensitive or confidential information, cyber - attacks and other security breaches or data leakages that could have a material adverse effect on Shire’s revenues, financial condition or results of operations; • Shire incurred substantial additional indebtedness to finance the Baxalta acquisition, which has increased its borrowing costs and may decrease its business flexibility ; • Our ongoing strategic review of our Neuroscience franchise may distract management and employees and may not lead to improved operating performance or financial results; there can be no guarantee that, once completed, our strategic review will result in any additional strategic changes beyond those that have already been announced; and a further list and description of risks, uncertainties and other matters can be found in Shire’s most recent Annual Report on Form 10 - K and in Shire’s subsequent Quarterly Reports on Form 10 - Q, in each case including those risks outlined in “ITEM 1A: Risk Factors”, and in subsequent reports on Form 8 - K and other Securities and Exchange Commission filings, all of which are available on Shire’s website. All forward - looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by this cautionary statement. Readers are cautioned not to place undue reliance on these forward - looking statements that speak only as of the date hereof. Except to the extent otherwise required by applicable law, we do not undertake any obligation to update or revise forward - looking statements, whether as a result of new information, future events or otherwise.

(1) Pro forma for acquisition of Baxalta (acquired on June 3, 2016). (2) This is a Non GAAP financial measure as a percentage of total revenue. The most directly comparable measure under US GAAP is Net Income Margin (Q3 2017: 15%, Q2 2017: 6%, Q1 2017: 10%, Q4 2016: 12%, Q3 2016: - 11%). For reconciliations of US GAAP net income to Non GAAP EBITDA for Q3 2017 and Q3 2016, see page 21 of our Q3 2017 earnings rel ea se. (3) This is a Non GAAP financial measure. Non GAAP net debt represents cash and cash equivalents less short and long term borrowi ngs , capital leases and other debt. Reported Non GAAP EBITDA on a trailing 12 month basis were used for this calculation. The most directly comparable measure for EBITDA under US GAAP is Net Income ( Q3 2017: $551m, Q2 2017: $240m, Q1 2017: $375m, Q4 2016: $457m, Q3 2016: - $387m). For reconciliations of US GAAP net income to Non GAAP EBITDA for Q3 2017 and Q3 2016, see page 21 of our Q3 2017 earnings rel ea se.

This presentation contains financial measures not prepared in accordance with US GAAP. These measures are referred to as “Non GAAP” measures and include: Non GAAP operating income; Non GAAP net income; Non GAAP diluted earnings per ADS; effective tax rate on Non GAAP income before income taxes and (losses/earnings) of equity method investees (effective tax rate on Non GAAP income); Non GAAP CER; Non GAAP cost of sales; Non GAAP gross margin; Non GAAP R&D; Non GAAP SG&A; Non GAAP other expense; Non GAAP free cash flow, Non GAAP net debt, Non GAAP EBITDA and Non GAAP EBITDA margin. The Non GAAP measures exclude the impact of certain specified items that are highly variable, difficult to predict, and of a size that may substantially impact Shire’s operations. Upfront and milestone payments related to in - licensing and acquired products that have been expensed as R&D are also excluded as specified items as they are generally uncertain and often result in a different payment and expense recognition pattern than ongoing internal R&D activities. Intangible asset amortization has been excluded from certain measures to facilitate an evaluation of current and past operating performance, particularly in terms of cash returns, and is similar to how management internally assesses performance. The Non GAAP financial measures are presented in this presentation as Shire’s management believes that they will provide investors with an additional analysis of Shire’s results of operations, particularly in evaluating performance from one period to another. Shire’s management uses Non GAAP financial measures to make operating decisions as they facilitate additional internal comparisons of Shire’s performance to historical results and to competitor’s results, and provides them to investors as a supplement to Shire’s reported results to provide additional insight into Shire’s operating performance. Shire’s Remuneration Committee uses certain key Non GAAP measures when assessing the performance and compensation of employees, including Shire’s executive directors. The Non GAAP financial measures used by Shire may be calculated different from, and therefore may not be comparable to, similarly titled measures used by other companies - refer to the section “Non GAAP Financial Measure Descriptions” below for additional information. In addition, these Non GAAP financial measures should not be considered in isolation as a substitute for, or as superior to, financial measures calculated in accordance with US GAAP, and Shire’s financial results calculated in accordance with US GAAP and reconciliations to those financial statements should be carefully evaluated. Non GAAP Financial Measure Descriptions Where applicable the following items, including their tax effect, have been excluded when calculating Non GAAP earnings and from our Non GAAP outlook: Amortization and asset impairments: • Intangible asset amortization and impairment charges; and • Other than temporary impairment of investments. Acquisitions and integration activities: • Up - front payments and milestones in respect of in - licensed and acquired products; • Costs associated with acquisitions, including transaction costs, fair value adjustments on contingent consideration and acquired inventory; • Costs associated with the integration of companies; and • Noncontrolling interests in consolidated variable interest entities. Divestments, reorganizations and discontinued operations: • Gains and losses on the sale of non - core assets; • Costs associated with restructuring and reorganization activities; • Termination costs; and • Income/(losses) from discontinued operations. Legal and litigation costs: • Net legal costs related to the settlement of litigation, government investigations and other disputes (excluding internal legal team costs). Additionally, in any given period Shire may have significant, unusual or non - recurring gains or losses which it may exclude from its Non GAAP earnings for that period. When applicable, these items would be fully disclosed and incorporated into the required reconciliations from US GAAP to Non GAAP measures. Depreciation, which is included in Cost of sales, R&D and SG&A costs in our US GAAP results, has been separately disclosed for presentational purposes. Free cash flow represents net cash provided by operating activities, excluding up - front and milestone payments for in - licensed and acquired products, but including capital expenditure in the ordinary course of business. Non GAAP net debt represents cash and cash equivalents less short and long term borrowings, capital leases and other debt. 2020 Financial Targets A reconciliation of 2020 Non GAAP tax rates to the US GAAP tax rates cannot be provided because we are unable to forecast with reasonable certainty many of the items necessary to calculate such comparable GAAP measures, including asset impairments, acquisitions and integration related expenses, divestments, reorganizations and discontinued operations related expenses, legal settlement costs, as well as other unusual or non - recurring gains or losses . These items are uncertain, depend on various factors, and could be material to our results computed in accordance with GAAP. We believe the inherent uncertainties in reconciling Non GAAP measures for periods after 2018 to the most comparable GAAP measures would make the forecasted comparable GAAP measures nearly impossible to predict with reasonable certainty and therefore inherently unreliable. Non GAAP financial measures 28
