Shire plc: Excellent Performance Across All Areas of the Business and Accelerating New Product Sales Drive Revenue Growth of 36%

BASINGSTOKE, England and PHILADELPHIA, February 21 /PRNewswire-FirstCall/ -- Shire plc (LSE: SHP, NASDAQ: SHPGY) the global specialty biopharmaceutical company announces results for the twelve months to December 31, 2007 - a year which has seen significant growth in launched products.

(1) New product sales include VYVANSE, LIALDA/MEZAVANT, DYNEPO, ELAPRASE, FOSRENOL and DAYTRANA

Matthew Emmens, Chief Executive Officer, commented:

"Shire had an excellent 2007, growing sales from our portfolio of both new and established products by a total of 41% and raising revenue guidance throughout the course of the year. We generated substantial cash inflows from operations of $475 million, after expending $156 million on the acquisition of new product candidates in both our Human Genetic Therapies and Specialty Pharmaceutical businesses. Based on these strong results we were able to bring forward several new R&D programs.

During the year, we undertook three major new product launches - VYVANSE, LIALDA / MEZAVANT and DYNEPO - which have gone well and also continued the roll-out of ELAPRASE and FOSRENOL into new geographies. These products, together with DAYTRANA that was launched last year, represented 32% of our fourth quarter product sales.

The acquisition of New River Pharmaceuticals gave us full ownership and control of VYVANSE, and this new generation ADHD treatment is establishing itself in the US, where it has already gained a market share of 6%(i). The launch of VYVANSE continues to progress well and we are confident about the medication's future growth supported by new clinical studies and expected additional indications. Our total ADHD franchise has now grown to 32% of the total US ADHD market, compared to 28% at the end of 2006, extending our leadership position in this specialist area.

We've also acquired five pipeline compounds in new technologies and new markets, by licensing the marketing and co-development rights to a range of both biological and small molecule products from Renovo, Amicus Therapeutics and Alba Therapeutics.

Looking forward, we will continue to execute our strategy, which has provided good returns for shareholders, by building on the success of our growing specialist drugs portfolio focused on the treatment of symptomatic diseases. We currently expect 2008 revenue growth to be in the mid to high teens range and positive revenue growth through 2010."

Pipeline Highlights

Shire has expanded its product pipeline by in-licensing the following drug compounds and technologies in 2007:

- JUVISTA(R)

- In August 2007 Shire acquired exclusive rights to develop and commercialize JUVISTA worldwide (with the exception of EU member states) from Renovo Limited ("Renovo"). JUVISTA, which is being investigated for the prevention and reduction of scarring in connection with surgery, is in late Phase 2 development.

- Seven Phase 2 efficacy trials for JUVISTA have now been reported of which six demonstrated statistically significant efficacy. Phase 2 clinical trials in multiple other surgery types are ongoing and are expected to report during 2008 and 2009.

- Pharmacological chaperone compounds for Lysosomal Storage Disorders ("LSDs") - In November 2007 Shire in-licensed from Amicus Therapeutics, Inc. ("Amicus") the rights to three compounds in markets outside the US:

- AMIGAL(TM) for Fabry disease (Phase 2) received orphan drug designation by the EMEA, which may provide it with up to ten years market exclusivity in the EU;

- PLICERA(TM) for Gaucher disease (Phase 2) received orphan drug designation by the EMEA, which may provide it with up to ten years market exclusivity in the EU; and

- AT2220 for Pompe disease is currently in Phase 1 clinical trials.

- SPD550 (Larazotide Aceotate) for Gastro Intestinal ("GI") disorders - In December 2007 Shire licensed rights to SPD550 (also known as AT-1001), in markets outside of the US and Japan, from Alba Therapeutics Corporation ("Alba"). SPD550 is Alba's lead inhibitor of barrier dysfunction in various GI disorders and is currently in Phase 2 development for the treatment of Celiac disease.

- SPD487 (Amphetamine transdermal system ("ATS")) - ADHD - In June 2007 Shire acquired exclusive development rights to ATS following completion of early development work by Noven.

During 2007 Shire has made $155.9 million of up-front payments for the in-licensing of the above products comprising $75.0 million to Renovo, $50.0 million to Amicus, $25.0 million to Alba and $5.9 million to Noven. Shire also made a $50 million equity investment in Renovo Group plc.

Existing pipeline developments:

- VYVANSE for ADHD in adult patients

- In September 2007, the FDA accepted the filing of a supplemental New Drug Application for VYVANSE for the treatment of ADHD in adult patients. The Prescriptions Drug User Fee Act ("PDUFA") action date is April 28, 2008.

- On October 25, 2007 Shire released results from the Phase 3 clinical trials in adults. In this double-blind, placebo-controlled, four-week study with dose escalation in 414 adults aged 18 to 55 years, treatment with VYVANSE at all doses studied (30mg, 50mg, 70mg) was significantly more effective than placebo.

- Adults represent the largest and fastest growing segment of the ADHD market with a total of 9.9 million patients, of which 7.5 million are untreated.

- DAYTRANA - ADHD - Regulatory submissions were filed for approval of the product with Health Canada on November 29, 2007 and with the Netherlands, as the reference member state for approval in the EU via the decentralized procedure, on December 12, 2007.

- INTUNIV(TM) (previously known as SPD503) - ADHD - A non-stimulant "non-scheduled" medication for the treatment of ADHD. In June 2007 Shire received an approvable letter from the FDA for INTUNIV. Shire is in discussions with the FDA regarding additional clinical work which is designed to enhance the label. While the precise timing of the approval of INTUNIV is unknown, Shire now anticipates that launch will occur in H2 2009.

- SPD465 - ADHD - In May 2007 Shire received an approvable letter from the FDA. Shire is not currently taking any steps to move this product towards approval.

- FOSRENOL - Hyperphosphatemia - On October 16, 2007 the FDA Cardiovascular and Renal Drugs Advisory Committee recommended by a majority vote the use of phosphate binders, including FOSRENOL, to treat hyperphosphatemia in CKD stage 4 patients. Shire is working with the FDA to explore the regulatory pathway to approval for use in pre-dialysis patients.

- LIALDA/MEZAVANT - Phase 3 worldwide clinical trials investigating the use of the product for the treatment of diverticulitis, a colonic disease, were initiated in 2007.

- Velaglucerase alfa (GA-GCB) - Gaucher disease - A worldwide Phase 3 clinical program was initiated in 2007 and is ongoing. It is anticipated that this development program will support filing of velaglucerase alfa from H2 2009.

- Whilst a number of preclinical products are underway in early stage development, Shire has discontinued the following projects: SPD491 (a pain product), SPD493 (formerly known as Valrocemide), SPD500 (Tissue protective cytokine technology) and NRP290 (a pain product acquired with the New River Pharmaceuticals Inc. ("New river") acquisition).

Business Highlights

- SPD754 (Apricitabine) - HIV - Shire licensed its residual rights (for the US and Canada) for the investigational HIV compound to Avexa Limited ("Avexa") on January 23, 2007. In return Shire received an upfront cash payment of $10 million and Avexa shares valued at approximately $3 million.

- In April 2007 Shire completed the acquisition of New River by way of a short-form merger for $64 per share, or approximately $2.6 billion, partly funded by a private equity placing of $0.9 billion in February 2007.

- In May 2007 Shire issued $1.1 billion principal amount of convertible bonds due 2014. The proceeds of the bonds were used by Shire to repay borrowings under its bank facilities previously drawn to partially fund the acquisition of New River.

- Product divestments - In December 2007 Shire completed the sale of a portfolio of non-core products, including SOLARAZE(R) and VANIQA(R) to Laboratorios Almirall S.A.

- In November 2007 Shire agreed to pay Applied Research Systems Holding N.V and Serono S.A. ("Serono") $12 million for a fully-paid, worldwide, non-exclusive license to Serono's patents related to gene-activation, including the US Patent No. 5,272,071. Serono's infringement suit against the Company in the Massachusetts's District Court was subsequently dismissed.

2008 Outlook

R&D pipeline and new product launches in the next two years

Subject to obtaining relevant regulatory/governmental approvals, the following product launches are planned over the next two years:

- MEZAVANT in the EU and Canada during 2008;

- VYVANSE for use in adult patients in the US in Q2 2008 (PDUFA date April 28, 2008);

Shire's business continues to perform strongly. We expect 2008 total revenue growth to be in the mid to high teens range with VYVANSE sales between $350 to $400 million, assuming that the adult indication is launched by mid year 2008.

Costs are estimated as follows:

- Phase 3(b) and Phase 4 studies to support existing launches in the Specialty Pharmaceuticals ("Specialty") business and new product development in both the Specialty and Human Genetic Therapies ("HGT") businesses will result in Research and Development ("R&D") spend for 2008 in the range of $450 to $475 million (or $465 to $490 million including FAS123R charge);

- Existing and planned launches will require additional advertising and promotional spend resulting in SG&A costs for 2008 in the range of $1,080 to $1,120 million (or $1,125 to $1,165 million including FAS123R charge);

- Business expansion including new and enlarged manufacturing and research facilities for HGT, the enlargement of other facilities and the global roll out of new and upgraded IT infrastructures, will see a significant cash investment in capital projects in 2008 in the range of $320 to $350million (2007: $110 million);

- Due to the higher capital expenditure, the depreciation charge for 2008 is expected to increase by approximately 50% compared to 2007 (2007: $59 million);

- The effective tax rate on non GAAP income from ongoing operations for 2008 is expected to be approximately 23%; and

- Fully diluted share capital (inclusive of options and convertible bonds) will be approximately 590 million shares, with $13 million of convertible bond interest (after tax) added back to net income for the purpose of calculating fully diluted EPS.

From 2008, Shire will report its non GAAP earnings based on net income/(loss) adjusted for the following items, all of which are excluded from the financial outlook for the full year as stated above:

- Intangible asset amortization charges, which are expected to rise approximately 25% over the 2007 charge of $95 million primarily due to a full year's amortization of the VYVANSE pediatric intangible asset;

- Release of deferred gains on the sale of non-core products, (including Almirall and other non-core product right gains), of $29 million; and

- Upfront payments and milestones in respect of in-licensed products.

In contrast to 2007, no adjustment will be made to exclude FAS123R charge from non GAAP earnings in 2008.

Dividend

In respect of the six months to December 31, 2007 the Board has resolved to pay a second interim dividend of 6.4690 US cents per ordinary share (2006: 5.2455 US cents per share). Together with the first interim payment of 2.147 US cents per ordinary share (2006: 1.935 US cents per share), this represents total dividends for 2007 of 8.616 US cents per share (2006: 7.180 US cents per share), an increase of 20% in US Dollar terms over 2006.

Dividend payments will be made in Pounds Sterling to Ordinary Shareholders and US Dollars to American Depositary Share ("ADS") holders. A dividend of 3.3151 pence per ordinary share and 19.407 US cents per ADS, respectively, will be paid. The Board has resolved to pay the dividend on April 3, 2008 to persons whose names appear on the register of members of the Company at the close of business on March 14, 2008.

Shire intends to pursue a progressive dividend policy.

Redemption of Exchangeable Shares

On February 12, 2008, a subsidiary of Shire exercised a redemption call right and purchased each exchangeable share of Shire Acquisition Inc. remaining in public ownership. Exchangeable shareholders received either three ordinary shares of Shire plc or one ADS (representing three ordinary shares of Shire plc) for each Exchangeable Share held. Exchangeable Shares were issued to Canadian resident shareholders of Biochem Pharma Inc. in 2001 as consideration for the acquisition by the Shire group of Biochem Pharma Inc. The Exchangeable Shares, which were listed on the Toronto Stock Exchange, have now been de-listed from the Toronto Stock Exchange.

Changes in Executive and Non-Executive Directors

In January 2007 Dr Jeffrey Leiden, MD, PhD joined Shire's Board of Directors as a Non-Executive Director and has been a member of the Remuneration and Nominations Committee since July 2007.

In May 2007 the Hon. James Grant, Q.C. retired from the Board following completion of his term of office.

In October 2007 David Mott joined Shire's Board of Directors as a Non-Executive Director and was appointed to Shire's Audit, Compliance and Risk Committee on December 12, 2007. Mr Mott is Chief Executive Officer and President of MedImmune, Inc, a role he was appointed to in 2000.

In December 2007 Shire announced its Board succession plans. Dr James H Cavanaugh will retire as Non-Executive Chairman; Matthew Emmens will succeed him as Non-Executive Chairman; and Angus Russell will be appointed as Chief Executive Officer. Shire is now working to identify a replacement Chief Financial Officer to ensure an orderly succession. These Board changes will become effective at Shire's AGM in June 2008, at which time David Kappler will be appointed as Deputy Chairman in addition to his existing role as Senior Independent Director.

Shire would like to thank the Hon. James Grant Q.C. for his contributions during six years of service.

Changes in Senior Management

In September 2007 Shire appointed Sylvie Gregoire as President of its HGT business.

Notes to editors

Shire plc

Shire's strategic goal is to become the leading specialty biopharmaceutical company that focuses on meeting the needs of the specialist physician. Shire focuses its business on attention deficit and hyperactivity disorder (ADHD), human genetic therapies (HGT), gastrointestinal (GI) and renal diseases. The structure is sufficiently flexible to allow Shire to target new therapeutic areas to the extent opportunities arise through acquisitions. Shire's in-licensing, merger and acquisition efforts are focused on products in niche markets with strong intellectual property protection either in the US or Europe. Shire believes that a carefully selected portfolio of products with relatively small-scale sales forces will deliver strong results.

Revenues from continuing operations for the year to December 31, 2007 increased by 36% to $2,436.3 million (2006: $1,796.5 million).

Operating loss for the year to December 31, 2007 was $1,379.1 million (2006: income of $283.2 million). The loss in 2007 primarily arose from the $1,866.4 million write-off of in-process research and development ("IPR&D") acquired as part of the $2.6 billion acquisition of New River; this amount represents the value of the acquired development projects, including VYVANSE for use in adult patients. Excluding IPR&D, operating income rose by $204.1 million compared to 2006, primarily due to revenue growth.

Cash inflow from operating activities for the year to December 31, 2007 decreased by 11% to $474.7 million (2006: $531.9 million). Excluding upfront payments and milestones in respect of in-licensed technology of $155.9 million in 2007 and $80.5 million in 2006 (see section 4 - R&D below for details), cash inflow from operating activities for the year to December 31, 2007 increased by 3% to $630.6 million (2006: $612.4 million). This increase is lower than the increase in operating income (excluding IPR&D) of $204.1 million primarily as a result of increased receivables generated by higher sales in December 2007 over December 2006 and increases in inventory to support new products.

Cash, cash equivalents and restricted cash at December 31, 2007 totaled $802.0 million (December 31, 2006: $1,156.7 million). The decrease of $354.7 million was primarily due to the acquisition of New River in April 2007 being partly funded from Shire's pre-acquisition cash resources.

Summary of Q4 2007

Revenues from continuing operations for the three months to December 31, 2007 increased by 46% to $724.5 million (2006: $497.0 million).

Operating income for the three months to December 31, 2007 was $232.2 million (2006: $80.4 million). The increase primarily resulted from higher revenues and related earnings in Q4 2007 (compared to Q4 2006) and gains on disposal of non-core products of $115.7 million (2006: $nil), which were partially offset by upfront payments for in-licensed technology totaling $75.0 million (2006: $nil).

Cash inflow from operating activities for the three months to December 31, 2007 decreased by 65% to $66.6 million (2006: $188.8 million). Excluding upfront payments and milestones in respect of in-licensed technology of $75.0 million in 2007 (2006: $nil) (see section 4 - R&D below for details), cash inflow from operating activities for the year to December 31, 2007 decreased by 25% to $141.6 million (2006: $188.8 million). This decrease was primarily as a result of increased receivables generated by higher sales in December 2007 over December 2006.

Specialty Pharmaceuticals

ADDERALL XR - ADHD

As a result of the launch of VYVANSE in July 2007 ADDERALL XR's average share of the US ADHD market for 2007 fell to 25.5% (2006: 26.1%). US prescriptions for ADDERALL XR for the year to December 31, 2007 increased by 3% compared to the same period in 2006 due to a 6% growth in the US ADHD market offset by the 0.6% fall in average market share.

Sales of ADDERALL XR for the year to December 31, 2007 were $1,030.9 million, an increase of 19% compared to the same period in 2006 (2006: $863.6 million). Product sales growth was higher than prescription growth due primarily to price increases in January and October 2007.

As previously disclosed, the United States Federal Trade Commission ("FTC") informed Shire on October 3, 2006 that it was reviewing the ADDERALL XR patent litigation settlement agreement between Shire and Barr Laboratories, Inc ("Barr"). On June 22, 2007, the Company received a civil investigative demand requesting that it provides information to the FTC relating to its settlement with Barr and its earlier settlement with Impax Laboratories, Inc. The Company is cooperating fully with this investigation and believes that the settlements are in compliance with all applicable laws.

Litigation proceedings concerning Shire's ADDERALL XR patents are ongoing. Further information on this litigation can be found in our filings with the SEC, including our Annual Report on Form 10-K for the year to December 31, 2006 and our most recent Quarterly Report on Form 10-Q for the period to September 30, 2007.

VYVANSE - ADHD

VYVANSE was launched in the US market in July 2007 and at December 31, 2007 its market share had reached 5.2% (average annual market share 1.8%). Product sales of $76.5 million for the year to December 31, 2007 were net of $42 million sales deductions, primarily coupons, wholesaler discounts and rebates, which are expected over time to trend to approximately 28% of product sales before sales deductions.

All initial launch stocks of VYVANSE totaling $57.8 million were recognised into revenue during the year to December 31, 2007.

DAYTRANA - ADHD

Product sales for the year to December 31, 2007 were $64.2 million (2006: $25.1 million). DAYTRANA's average share of the US ADHD market increased to 2.1% in 2007 compared to 0.8% in 2006 (DAYTRANA was launched in June 2006). US prescriptions of DAYTRANA for the year to December 31, 2007 over 2006 benefited from a full year of demand, 6% growth in the US ADHD market and higher market share. For the six month period to December 31, 2007 prescriptions of DAYTRANA were up 31% compared to the same period in 2006. During September 2007 Shire announced a voluntary market withdrawal of a limited quantity of DAYTRANA patches following feedback from patients and caregivers who had experienced difficulty in removing the release liner. Patches are now being manufactured using an enhanced process, which Shire believes offers improved ease of use when peeling off the release liner.

The addition of VYVANSE combined with ADDERALL XR and DAYTRANA's market share helped Shire grow its total share of the US ADHD market to 31.1% at December 31, 2007 compared to 28.0% at December 31, 2006. Shire has the leading portfolio of products in the US ADHD market.

PENTASA - Ulcerative colitis

US prescriptions of PENTASA for the year to December 31, 2007 were up 3% compared to the same period in 2006 primarily due to a 4% increase in the US oral mesalamine prescription market, offset by a 0.1% decrease in PENTASA's average market share from 17.3% in 2006 to 17.2% in 2007.

Sales of PENTASA for the year to December 31, 2007 were $176.4 million, an increase of 28% compared to the same period in 2006 (2006: $137.8 million). Sales growth is higher than prescription growth primarily due to restocking to normal levels in 2007 and the impact of price increases in November 2006 and August 2007.

LIALDA/MEZAVANT - Ulcerative colitis

Shire launched LIALDA in the US oral mesalamine market in March 2007, and by December 31, 2007 LIALDA had reached a market share of 8.0% (average annual market share 3.9%). LIALDA's product sales for the year to December 31, 2007 were $50.5 million. All initial launch stocks of LIALDA totaling $34.7 million were recognised into revenue during the year to December 31, 2007.

The product was launched in the UK in November 2007, Canada in January 2008 and further launches are planned in the EU during 2008, subject to the successful conclusion of pricing and reimbursement negotiations. In the UK and Ireland the product will be called MEZAVANT XL and Shire plans to market the product in most other EU countries as MEZAVANT.

Since the launch of LIALDA in March 2007, PENTASA and LIALDA's combined share of the US oral mesalamine prescription market had grown to 24.9% as at December 31, 2007, up from 17.6% as at December 31, 2006.

FOSRENOL - Hyperphosphatemia

FOSRENOL is now available in 24 countries and global sales totaled $102.2 million for the year to December 31, 2007 (2006: $44.8 million). Outside the US, FOSRENOL has now been launched in Germany, France, UK, Italy and Spain (in January 2008) and a number of other countries. Sales of FOSRENOL outside the US for the year ended December 31, 2007 were $40.1 million (2006: $4.6 million).

US sales of FOSRENOL for the year to December 31, 2007 were up 54% to $62.1 million compared to the same period in 2006 (2006: $40.2 million). FOSRENOL's average market share of the US phosphate binder market increased from 8.5% in 2006 to 8.6% in 2007. The increase in product sales is due to a small wholesaler stocking increase in 2007 compared to significant wholesaler de-stocking of initial launch stocks in 2006, the continued shift to the 1 gram strength tablet launched in 2006, partially offset by higher sales deductions in 2007 compared to the same period in 2006 (relating to a one-off provision made in 2007 for returns of the 750mg dose).

DYNEPO - Anemia associated with CKD

DYNEPO was launched in March 2007 in Germany and later in the year in the UK, France, Italy, and Ireland with sales for 2007 reaching $14.2 million.

CARBATROL - Epilepsy

US prescriptions for CARBATROL for the year to December 31, 2007 were down 5% compared to the same period in 2006. This was primarily due to a comparable decline in the US extended release carbamazepine prescription market; CARBATROL's average market share remained constant.

Sales of CARBATROL for the year to December 31, 2007 were $72.3 million, an increase of 6% compared to the same period in 2006 (2006: $68.3 million). Product sales increased despite the decrease in prescriptions, due to a sales price increase in April 2007 and restocking to normal levels, partially offset by higher sales deductions.

Patent litigation proceedings relating to CARBATROL are ongoing. Further information about this litigation can be found in our filings with the SEC, including our Annual Report on Form 10-K for the year to December 31, 2006 and our most recent Quarterly Report on Form 10-Q for the period to September 30, 2007.

XAGRID - Thrombocythemia

Sales for the year to December 31, 2007 were $66.8 million, an increase of 25% compared to the same period in 2006 (2006: $53.3 million). Expressed in transaction currencies (XAGRID is primarily sold in Euros and Pounds sterling), sales increased by 15% due to growth in many of Shire's existing markets, with exchange rate movements against the US dollar accounting for the remaining 10% increase.

Human Genetic Therapies

REPLAGAL - Fabry disease

Sales for the year to December 31, 2007 were $143.9 million, an increase of 22% compared to the same period in 2006 (2006: $117.7 million). Expressed in transaction currencies (REPLAGAL is primarily sold in Euros and Pounds sterling) sales increased by 13% due to higher unit sales in Europe and Canada and the continued roll out of REPLAGAL to new countries, including those in Latin America, with REPLAGAL now approved in 41 countries (including Japan). Exchange rate movements against the US dollar accounted for the remaining 9% increase in sales.

ELAPRASE - Hunter syndrome

Sales for the year to December 31, 2007 were $181.8 million (2006: $23.6 million). Sales growth in 2007 was driven primarily by a full year of sales in the US (ELAPRASE was launched in the US in August 2006), sales in Europe (ELAPRASE was launched in several European markets in the first half of 2007), and pre-approval sales in several Latin American markets. ELAPRASE was approved for sale and marketing in Japan in October 2007 and is now approved for marketing and commercial distribution in 37 countries worldwide.

3. Royalties

Royalty revenue increased to $247.2 million for the year ended December 31, 2007 (2006: $242.9 million).

Royalties from sales of 3TC for the year to December 31, 2007 were $145.3 million, a decrease of 4% compared to the same period in 2006 (2006: $150.9 million). Excluding favorable foreign exchange movements of 4%, there has been a decline of 8% compared to the same period in 2006.

Shire receives royalties from GSK on worldwide 3TC sales. GSK's worldwide sales of 3TC for the year to December 31, 2007 were $1,110 million, a decrease of 2% compared to the same period in 2006 (2006: $1,138 million), but a decrease of approximately 7% on a constant exchange rate basis. While the nucleoside analogue market for HIV has continued to grow, competitive pressures within the market have increased leading to a decline in 3TC sales.

In 2007 generic drug companies filed Abbreviated New Drug Applications ("ANDA") seeking approval for EPIVIR, COMBIVIR, ZEFFIX and EPZICOM in the US. Pursuant to the GSK/Shire license for lamivudine products, GSK has the right to enforce the licensed patents. In November 2007 GSK filed a patent infringement lawsuit against Teva Pharmaceuticals, Inc. (Teva) in the US District Court for the District of Delaware for infringement of one of the patents relating to COMBIVIR. The patent, which covers the combination of AZT and lamivudine to treat HIV, expires in May 2012. Teva had filed an ANDA with the FDA with a certification of invalidity, unenforceability and non-infringement of that combination patent. Teva did not challenge two other patents relating to COMBIVIR that expire in 2010 and 2016. The case is in its early stages.

ZEFFIX - Chronic hepatitis B infection

Royalties from sales of ZEFFIX for the year to December 31, 2007 were $41.0 million, an increase of 18% compared to the same period in 2006 (2006: $34.8 million). The impact of foreign exchange movements has contributed 8% to the reported growth; excluding favorable foreign exchange movements there has been an increase of 10% compared to the same period in 2006.

Shire receives royalties from GSK on worldwide ZEFFIX sales. GSK's worldwide sales of ZEFFIX for the year to December 31, 2007 were $341 million, an increase of 13% compared to the same period in 2006 (2006: $301 million). This increase was mainly due to strong growth in the Chinese market and favorable foreign exchange rate movements.

Other

Other royalties are primarily in respect of REMINYL and REMINYL XL (known as RAZADYNE and RAZADYNE ER in the US), a product marketed worldwide (excluding the UK and the Republic of Ireland) by Janssen Pharmaceutical N.V. ("Janssen"), an affiliate of Johnson & Johnson. Shire has the exclusive marketing rights in the UK and the Republic of Ireland.

Barr and other companies have filed ANDA with the FDA for generic versions of RAZADYNE. Janssen and Synaptech Inc. ("Synaptech") have filed lawsuits against some of those ANDA filers. A trial was held during the week of May 21, 2007. No decision from the court has been issued to date.

Janssen and Synaptech filed lawsuits against Barr and Sandoz Inc. ("Sandoz") for infringement of their patent rights relating to RAZADYNE ER as a result of Barr and Sandoz filing ANDAs with the FDA for generic versions of RAZADYNE ER. No court dates have been set.

4. Financial details Cost of product sales

For the year to December 31, 2007 the cost of product sales was 14% of product sales (2006: 16%). The cost of product sales for REPLAGAL in 2006 included a $47.0 million (3% of product sales) adjustment in respect of inventories acquired through the acquisition of TKT. Excluding the impact of this fair value adjustment, cost of product sales as a percentage of product sales in 2006 was 13%. The increase in cost of product sales as a percentage of products sales in 2007 over 2006 was primarily due to a shift in product mix resulting from increased sales of launched products, which had lower margins than existing products, and the write-off of inventory following the voluntary market withdrawal of a limited quantity of DAYTRANA patches.

R&D expenditure increased to $566.6 million for the year to December 31, 2007 (26% of product sales), up from $380.5 million in the year to December 31, 2006 (25% of product sales). For the year to December 31, 2007 R&D included upfront and milestone payments, totaling $155.9 million(1), for the in-licensing of pipeline products, (7% of product sales). For the year to December 31, 2006 R&D included $80.5 million(2) of upfront and milestone payments (5% of product sales).

Excluding these upfront and milestone payments and share based compensation costs (see reconciliation table above and share based compensation costs below) R&D expenditure for the year to December 31, 2007 increased by $99.1 million over the same period in 2006, decreasing as a percentage of product sales to 18% (2006: 19%). Contributing to the increased R&D expenditure in 2007 were Phase 3(b) and Phase 4 studies to support new product launches; the continuation of Phase 3 trials on velaglucerase alfa (GA-GCB); the development of the Women's Health franchise and JUVISTA; and the pre-clinical development of three HGT projects and the newly in-licensed Amicus products.

For the year to December 31, 2007 R&D included a charge of $17.0 million for share based compensation (2006: $5.4 million) which included a $4.6 million cumulative catch up charge in respect of 2005 awards, see page 18.

1 Upfront and milestone payments in 2007 were made to Renovo $75.0 million, Amicus $50.0 million, Alba $25.0 million and Noven $5.9 million.

2 Upfront and milestone payments in 2006 were made to New River $50.0 million, Duramed Pharmaceuticals Inc. ("Duramed") $25.0 million and Warren Pharmaceuticals Inc ("Warren") $5.5 million.

SG&A expenses increased to $1,041.7 million for the year to December 31, 2007 from $835.4 million in the year to December 31, 2006, an increase of 25% which was substantially less than the product sales increase of 41%.

The increase in SG&A expenses included the impact of the following:

- An increase in the ADHD sales force to promote VYVANSE;

- The cost of the new GI sales force in the US;

- The advertising, promotional and marketing spend to support the launches of VYVANSE, LIALDA and ELAPRASE; and

- A net charge of $17.0 million in respect of legal settlements, being a charge of $27.0 million for settlement of the TKT purported securities fraud class action shareholder suit partially offset by a $10.0 million release of existing legal provisions.

Excluding the net charge for legal settlements and share based compensation costs (see reconciliation table above and share based compensation costs details below) SG&A expenses, for the year to December 2007 increased by $171.0 million over the same period in 2006, decreasing as a percentage of product sales to 45% (2006: 52%).

For the year to December 31, 2007 SG&A included a charge of $52.7 million for share based compensation (2006: $34.4 million), which included a $22.5 million cumulative catch up charge in respect of 2005 awards, see page 18.

Depreciation and amortization

The depreciation charge for the year to December 31, 2007 was $59.3 million (2006: $43.3 million), inclusive of impairment charges of $1.8 million (2006: $0.5 million). The increase in depreciation follows investment in Shire's infrastructure to support the continuing growth of the Company.

The amortization charge for the year to December 31, 2007 was $95.0 million (2006: $57.4 million), inclusive of impairment charges of $0.4 million (2006: $1.1 million). The increased charge is primarily due to the amortization of DAYTRANA, DYNEPO and VYVANSE intangible assets following the product launches in June 2006, March 2007 and July 2007 respectively.

Integration costs

For the year to December 31, 2007 Shire incurred $1.3 million of costs associated with the integration of the New River business (2006: $5.6 million relating to the TKT acquisition). New River is now fully integrated and no further integration costs are anticipated.

Gain on sale of product rights

For the year to December 31, 2007 Shire recognized gains of $127.8 million on the sale of non-core products.

Shire received $209.6 million (net of costs of $2.2 million) from Almirall for a portfolio of non core products comprising the dermatology products SOLARAZE and VANIQA and six non-promoted products across a range of indications, which were sold by Shire primarily in the UK, France, Germany, Italy, Spain and Ireland. This sale realized a total gain of $139.2 million, of which $114.8 million was recognized during Q4 2007. The remaining deferred gain of $24.4 million will be recognized in 2008 after the transfer of the relevant consents.

Shire received $24.8 million on the sale of other non-core products, realizing a total gain of $17.2 million, of which $13.0 million was recognized during 2007. The remaining deferred gain of $4.2 million relating to these disposals is expected to be recognized in 2008 on the transfer of marketing authorizations.

During the year to December 31, 2006 Shire recognized a gain of $63.0 million on the disposal of ADDERALL to Duramed.

In-process R&D

During the year to December 31, 2007, as required under US GAAP (business combination accounting), the Company expensed the portion of the New River purchase price allocated to IPR&D of $1,866.4 million (2006: $nil). This amount represents the value of those acquired development projects which, at the acquisition date, had not been approved by the FDA or other regulatory authorities, including VYVANSE for use in adult patients. During Q4 2007 Shire reduced the amount assigned to IPR&D by $29.6 million as a result of changes to preliminary estimates of deferred taxes in the purchase price allocation exercise.

Interest income

For the year to December 31, 2007 Shire received interest income of $50.6 million (2006: $50.5 million). Interest income primarily relates to interest received on cash balances. Included in 2006 was interest of $6.5 million received from IDB Biomedical Inc. ("IDB") on repayment of injectable flu development drawings arising on the disposal of the vaccines business in 2004. Excluding this one-off item, interest income in 2007 is higher than in 2006 due to slightly higher average cash balances and higher average US Dollar interest rates.

Interest expense

For the year to December 31, 2007 Shire incurred interest expense of $70.8 million (2006: $26.4 million). The increase in interest expense follows the acquisition of New River which was partly funded by $1.3 billion of term loans, utilized under the $2.3 billion Multicurrency Term and Revolving Facilities Agreement. These term loans were subsequently partially repaid using the proceeds from Shire's $1.1 billion 2.75% convertible bond issued in May 2007. The remaining $200 million of the term loans was also repaid during June 2007. Interest expense for the year to December 31, 2007 includes a $7.9 million write-off of deferred financing costs following the repayment of these term loans.

In the years to December 31, 2007 and 2006 interest expense includes a provision for interest, which may be awarded by the Court in respect of amounts due to those ex-TKT shareholders who have requested appraisal of the acquisition consideration payable for their TKT shares. A trial date for the appraisal rights litigation has been set for May 12, 2008. Further information about this litigation can be found in our filings with the SEC, including our Annual Report on Form 10-K for the year to December 31, 2006 and our most recent Quarterly Report on Form 10-Q for the period to September 30, 2007.

Taxation

The effective tax rate for the year to December 31, 2007 was -4.0% (2006: 26.8%). Excluding the IPR&D charge of $1,866.4 million, which is not tax deductible, and the tax effect of items excluded from non-GAAP income as outlined on page 30, the effective rate of tax on non-GAAP income is 20.7% (2006: 26.8%).

The effective rate of tax under US GAAP in 2007 compared to 2006 benefited from: the tax effect of Shire plc's 2.75% convertible bonds; an increase in R&D tax credits; favorable permanent differences arising on the gain on sale of product rights and a net reduction in valuation allowances. These reductions to the effective rate of tax are partially offset by a net increase to the provision for uncertain tax benefits and associated interest and penalties of $38.1 million.

At December 31, 2007 net deferred tax liabilities of $56.7 million (December 31, 2006: net deferred tax asset of $261.0 million) were recognized. Shire has moved from a net deferred tax asset to a net deferred tax liability position primarily because of the recognition of a deferred tax liability of $394.8 million at acquisition in respect of intangible assets acquired with New River, offset by deferred tax asset of $46.7 million relating to New River's net operating loss carry forwards.

Equity in earnings of equity method investees

Net earnings of equity method investees of $1.8 million were recorded for the year to December 31, 2007 (2006: $5.7 million). This comprised earnings of $6.5 million from the 50% share of the anti-viral commercialization partnership with GSK in Canada (2006: $6.2 million), offset by losses of $4.7 million being the Company's share of losses in the GeneChem, AgeChem and EGS Healthcare Funds (2006: losses of $0.5 million).

FAS123R compensation cost

The total FAS123R charge for the year was $75.2 million (2006: $43.0 million). Excluding a catch-up charge of $29.2 million there was a 7% increase in the FAS123R charge over 2006.

The catch up charge relates to options issued by Shire in 2005 under the 2000 Executive Scheme. This charge arises as a result of the strong growth in revenue and profits which the Company has generated in Q4 2007. This growth has in turn caused the Company to revise its original assumptions on which the FAS123R charge was based.

(1) Cost of product sales does not include amortization of intangible assets relating to intellectual property rights acquired, which is included in Depreciation and amortization. Amortization of intangible assets in respect of favorable manufacturing contracts is recorded in cost of product sales.

(2) Costs, predominately relating to manufacturing set-up costs for new products, of $1.8 million and $7.2 million for the three and twelve months to December 31, 2007 respectively, have been reclassified from Research and development to Cost of product sales ($1.6 million and $6.4 million for the three and twelve months to December 31, 2006).

Unaudited US GAAP results for the three months and years to December 31, 2007 and 2006

(2) Excludes shares purchased by the Employee Stock Ownership Trust and presented by the Company as treasury stock.

(3) Calculated using the treasury stock method.

The share equivalents not included in the calculation of the diluted weighted average number of shares are shown below:

(1) For the three months ended December 31, 2007 and the three and twelve months ended December 31, 2006, certain stock options have been excluded from the calculation of diluted EPS because their exercise prices exceeded Shire plc's average share price during the calculation period.

(2) For the twelve months ended December 31, 2007, no share options, warrants or ordinary shares underlying convertible bonds were included in the calculation of the diluted weighted average number of shares, because the Company made a net loss during the calculation period and the inclusion of these items would be anti-dilutive.

(1) Excluding products divested in 2007, other product sales were $10.2 million for Q4 2007 (Q4 2006:$10.3 million)

(1) Excluding products divested in 2007, other product sales were $40.5 million for 2007 (2006:$41.5 million)
