Shire Pharmaceuticals Group plc 2007 Guidance Upgraded as Revenue Growth Accelerates

BASINGSTOKE, England and PHILADELPHIA, July 26 /PRNewswire-FirstCall/ -- Shire plc the global specialty biopharmaceutical company announces results for the second quarter 2007.

Q2 2007 Financial Highlights - Product sales up 34% to US$504 million; - Total revenues up 31% to US$575 million; - Net cash provided by operating activities up 33% to US$183 million; and

- 2007 revenue growth is now expected to be at least 25% (previous guidance: low 20% range).

Matthew Emmens, Chief Executive Officer, commented:

“We continue to execute our strategy effectively and this is reflected in the delivery of an excellent second quarter. Revenues were up 31%, led by ADDERALL XR and DAYTRANA in a growing ADHD market. ELAPRASE also made a significant contribution to overall growth as did our other new products FOSRENOL and LIALDA. For the half year, total revenues grew by 30%, with strong operating cash generation.

Importantly, we have just launched VYVANSE, our next generation ADHD product. We believe this product is best in class and early results are promising with positive feedback from both physicians and patients. In addition, we have received two FDA approvable letters in the ADHD category - for INTUNIV, a non-stimulant treatment for ADHD, and SPD465, a longer acting version of ADDERALL XR for the treatment of adult ADHD.

Our business continues to broaden into biopharmaceuticals. Our in-licensing of JUVISTA, a protein candidate for the prevention and reduction of scarring in connection with both therapeutic and cosmetic surgery, fits well within our model of focusing on the specialist physician. JUVISTA could become the first agent with such an indication and has the potential to create a substantial market.

With established positions in major pharmaceutical territories, we are now expanding into selected newer, faster growing markets in a measured way.

Shire has never been stronger and we now expect revenue growth in 2007 to be not less than 25%. We have impressive and well focused product franchises and we continue to bring in new projects, strengthening our pipeline.”

Business Highlights

JUVISTA(R) (Human TGFBeta3)

On June 19, 2007 Shire signed an agreement with Renovo Limited (“Renovo”) to develop and commercialize JUVISTA, Renovo’s novel drug candidate in late Phase 2 development. JUVISTA is being studied for the prevention and reduction of scarring in connection with both cosmetic and therapeutic surgery; areas often paid for “out of pocket” by patients choosing elective surgery. Under the terms of the agreement Shire has the exclusive right to commercialize JUVISTA worldwide, with the exception of EU member states. Phase 3 trials for JUVISTA are expected to commence in mid 2008.

Following the expiration of the Hart Scott-Rodino (“HSR”) waiting period of 30 days commencing July 11, 2007, Shire will pay Renovo US$75 million (expensed as R&D for US GAAP purposes) and will make an equity investment in Renovo Group plc of US$50 million (at a subscription price of GBP2 per share, which represents approximately 7% of Renovo’s share capital). In addition, Shire will pay Renovo US$25 million on filing of JUVISTA with the US Food and Drug Administration (“FDA”), up to US$150 million on FDA approval, royalties on net sales of JUVISTA and up to US$525 million on the achievement of very significant sales targets.

Issue of Convertible Bonds

In May 2007 Shire issued US$1.1 billion principal amount of Convertible Bonds due 2014. The proceeds of the issue were used by Shire to repay borrowings under its bank facilities previously drawn to partially fund the acquisition of New River Pharmaceuticals Inc. (“New River”). The bonds are convertible into ordinary shares of Shire plc, have a semi-annual coupon of 2.75% per annum and an initial conversion price of US$33.5879 per ordinary share (equivalent to US$100.7637 per American Depository Share (“ADS”)).

New River Acquisition

On April 19, 2007 Shire completed the acquisition of New River by way of a short-form merger for US$64 per share, or approximately US$2.6 billion. The acquisition of New River allows Shire to capture the full economic value of VYVANSE(TM) and gain control of the future development and commercialization of this product.

Product Highlights

VYVANSE(TM) (lisdexamfetamine dimesylate) - Attention Deficit Hyperactivity Disorder (“ADHD”).

On May 3, 2007 the US Drug Enforcement Administration (“DEA”) classified VYVANSE as a Schedule II controlled substance, consistent with the earlier recommendation of the FDA. VYVANSE is indicated for the treatment of ADHD in children aged six to twelve years old. The VYVANSE launch meeting took place in the week commencing June 25, 2007. Shire’s ADHD sales force is now actively promoting this product.

LIALDA(TM) (mesalamine) - Ulcerative colitis

On March 19, 2007 LIALDA was launched in the US. By July 13, 2007 LIALDA had achieved a US market share of 4.2%. Preparations are underway for the launch of the product, known as MEZAVANT(TM) in the EU, in the second half of this year.

DYNEPO(R) (epoetin delta) - Anemia associated with chronic kidney disease

Following the launch of DYNEPO in Germany in Q1 2007, this quarter saw the launch of DYNEPO in the UK.

FOSRENOL(R) (lanthanum carbonate) - Hyperphosphatemia

FOSRENOL was launched in Italy and Canada in Q2 2007. FOSRENOL has now been launched in 21 countries. FOSRENOL’s European sales for the three months to June 30, 2007 were US$9.0 million (2006: US$0.3 million). In addition sales of FOSRENOL in the US have increased from US$5.9 million in Q2 2006 to US$15.5 million in Q2 2007.

ELAPRASE(TM) (idursulfase) - Hunter syndrome

On June 14, 2007 Health Canada (under priority review) approved ELAPRASE for sale and marketing in Canada. ELAPRASE had been made available on a limited basis to Canadian patients since January 2007 through Health Canada’s Special Access Program and reimbursement discussions across Canada are now underway to enable widespread access. In less than eleven months since its first approval in the US, ELAPRASE is now available in 25 countries and sales for the three months to June 30, 2007 were US$42.7 million.

Pipeline Highlights

VYVANSE - ADHD (adult)

On June 29, 2007 Shire submitted a supplemental New Drug Application to the FDA for VYVANSE for the treatment of ADHD in adults. This application is subject to a ten month FDA review period. Shire expects to release results from the Phase 3 clinical trials in Q4 2007.

INTUNIV(TM) (guanfacine) extended release (previously known as SPD503) - ADHD

On June 21, 2007 Shire received an approvable letter from the FDA for INTUNIV, a non-stimulant selective alpha-2A-receptor agonist. Shire is seeking approval of INTUNIV as monotherapy for the treatment of ADHD symptoms throughout the day in children aged six to 17 years. Shire is working with the FDA to provide a full and timely response to the agency’s request.

Amphetamine transdermal system (“ATS”) - ADHD

In June 2007 following completion by Noven Pharmaceuticals Inc. (“Noven”) of Phase 1 studies for ATS, Shire paid US$5.9 million to Noven to acquire exclusive development rights to ATS.

SPD465 - ADHD

On May 19, 2007 Shire received an approvable letter from the FDA for SPD465, an investigational oral stimulant intended to provide symptom control of ADHD in adults for up to 16 hours with one daily dose. Shire is evaluating its response to the approvable letter.

ELAPRASE (idursulfase) - Hunter Central Nervous System (“Hunter CNS”)

In June 2007 Shire HGT had a pre-Investigational New Drug meeting with the FDA to finalize plans for the Phase 1 clinical trial program for Hunter CNS. The program remains on track for initiation of clinical trials in 2008.

2007 Financial Outlook

Following the strong performance this quarter, we have amended the previous guidance given as part of the Q1 2007 results:

- 2007 revenue growth is now upgraded to be not less than 25% (previous guidance: low 20% range) assuming prescription growth in the ADHD market of 5-7% (previous guidance: 4-6%);

- As in 2006, earnings for 2007 will be impacted by the costs associated with the continued development, launch and roll-out of new products. We currently expect these costs to be at the upper end of the ranges set out below, which include products and projects arising from the recent acquisition of New River and JUVISTA:

- Research and development spend for 2007 will be in the range of US$340 - US$360 million (unchanged from previous guidance).

- SG&A costs for 2007 will be in the range of US$930 - US$960 million (unchanged from previous guidance). The level of quarterly SG&A expenditure is expected to increase over the Q2 2007 spend as VYVANSE is launched in the US and MEZAVANT is launched in Europe.

- In addition:

- The depreciation charge for the year is expected to increase by approximately 20% compared to 2006 (unchanged from previous guidance); and

- The effective tax rate for 2007 is expected to be approximately 26% (unchanged from previous guidance).

Shire reports its non GAAP earnings based on net income/(loss) adjusted for certain items, and as from Q1 2007, excluding intangible asset amortization charges and the accounting impact of SFAS123R for share based compensation. The financial outlook for the full year stated above excludes the following items (all of which will be excluded from non GAAP net income):

- Intangible asset amortization charges, which are expected to rise by up to 80% over the 2006 charge of US$57.4 million (including US$1.1 million of impairments);

- The accounting impact of SFAS 123R estimated at approximately US$45 million (US$22 million for the 6 months ended 30 June 2007) (split for GAAP purposes between cost of product sales, R&D and SG&A in the approximate ratio of 10%, 20% and 70%, respectively);

- The in-process research and development (“IPR&D”) charge related to New River (US$1.9 billion);

- Up front payments for JUVISTA of US$75 million;

- Integration costs (including bridging finance costs) for the New River acquisition which are estimated to be approximately US$10 million (US$9.2 million incurred to date including bridging finance costs of US$7.9 million); and

- Other items as described on page 6 under Non GAAP Measures.

Dividend

In respect of the six months ended June 30, 2007, the Board resolved to pay an interim dividend of 2.147 US cents per ordinary share (2006: 1.935 US cents per share).

Dividend payments will be made in Pounds Sterling to Ordinary Shareholders, in US Dollars to holders of American Depository Shares and in Canadian Dollars to holders of Exchangeable Shares. A dividend of 1.048 pence per ordinary share (2006: 1.048 pence), 6.441 US cents per ADS (2006: 5.804 US cents) and 6.715 Canadian cents per Exchangeable Share (2006: 6.584 Canadian cents) will be paid. The Board resolved to pay the dividend on October 4, 2007 to persons whose names appear on the register of members of the Company (or to persons registered as holders of Exchangeable Shares in Shire Acquisition Inc.) at the close of business on September 14, 2007.

This is consistent with Shire’s stated policy of paying a dividend semi-annually, set in US cents per share. Dividend growth for the full year will be reviewed by the Board when the second interim dividend is determined. Shire intends to pursue a progressive dividend policy.

Non-Executive Director Changes

As part of the Board’s ongoing review of corporate governance matters, the following Non-Executive changes were announced on July 25, 2007: David Kappler, Chair of Shire’s Audit, Compliance and Risk Committee will take on the additional role of Senior Independent Director; Kate Nealon will take on the role of Chair of the Remuneration Committee; and Dr Jeff Leiden will join the Remuneration and Nomination Committees, each with immediate effect. Dr Barry Price has stepped down as Senior Independent Director, Chair of the Remuneration Committee and as a member of the Audit, Compliance and Risk Committee. Dr Price remains a Board member and a member of the Company’s Nomination Committee.

On May 10, 2007 non-executive director the Hon. James Grant Q.C. retired from the Board following completion of his term of office. The board thanks Mr Grant for his contribution during his six year term in office.

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 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 believes that a carefully selected portfolio of products with a strategically aligned and relatively small-scale sales force will deliver strong results.

Shire’s focused strategy is to develop and market products for specialty physicians. 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.

These measures are referred to as “non GAAP” measures and include Non GAAP income from ongoing operations, Non GAAP net income, Non GAAP diluted earnings per ordinary share and Non GAAP diluted earnings per ADS. These non GAAP measures exclude the effect of certain cash and non-cash items, both recurring and non-recurring, that Shire’s management believes are not related to the core performance of Shire’s business.

Introduction Summary of Q2 2007

Revenues from continuing operations for the three months to June 30, 2007 increased by 31% to US$574.9 million (2006: US$439.1 million).

The loss from continuing operations (before income taxes and equity in earnings of equity method investees) for the three months to June 30, 2007 was US$1,786.4 million (2006: income of US$83.8 million). The loss was due to the US$1,896.0 million write-off of IPR&D acquired as part of the US$2.6 billion acquisition of New River. This adjustment is required under US GAAP and represents the value of acquired intangible assets still under development, including the adult indication of VYVANSE.

Cash inflow from operating activities for the three months to June 30, 2007 increased by 33% to US$183.0 million (2006: US$137.4 million). This increase resulted mainly from higher sales in Q2 2007 compared to Q2 2006, partially offset by increased cash expenditure on operating costs and expenses.

Cash and cash equivalents, restricted cash and short-term investments at June 30, 2007 totaled US$638.0 million (December 31, 2006: US$1,156.7 million). The decrease in cash and cash equivalents during the first half of the year of US$528.4 million was primarily due to the acquisition of New River being partly funded from Shire’s pre-acquisition cash resources. The remaining funding for the New River acquisition comprised cash of US$0.9 billion raised from the equity placing during Q1 2007 and US$1.3 billion drawn from Shire’s loan facilities during Q2 2007.

2. Product sales

For the three months to June 30, 2007 product sales increased by 34% to US$504.2 million (2006: US$376.0 million) and represented 88% of total revenues (2006: 86%).

ADDERALL XR - ADHD

ADDERALL XR is the leading brand in the US ADHD market with an average market share of 26% during Q2 2007 (2006: 26%). US ADHD market growth of 8% resulted in a 9% increase in US prescriptions for ADDERALL XR for the three months to June 30, 2007 compared to the same period in 2006.

Sales of ADDERALL XR for the three months to June 30, 2007 were US$255.1 million, an increase of 16% compared to the same period in 2006 (2006: US$220.7 million). Product sales growth was higher than prescription growth due primarily to a price increase in January 2007.

Litigation proceedings concerning Shire’s ADDERALL XR patents are ongoing. Further information on this litigation can be found in our filings with the US Securities and Exchange Commission (“SEC”), including our Annual Report on Form 10-K for the year to December 31, 2006.

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.

VYVANSE - ADHD

VYVANSE was launched in the US in June 2007 following receipt of required regulatory approvals. Launch stocks of US$55.9 million (before sales deductions) were shipped to wholesalers during June 2007. In accordance with US GAAP, sales of these launch stocks have been deferred pending satisfaction of revenue recognition criteria. All launch stocks are expected to be recognized into revenue by the end of 2007.

DAYTRANA - ADHD

Following its launch in June 2006, DAYTRANA achieved an average market share during Q2 2007 of 2%, consistent with the previous quarter. Net sales for the three months to June 30, 2007 were US$19.9 million, compared to net sales of US$11.9 million for the first quarter of 2007. Net sales growth of US$8.0 million over the first quarter of 2007 is primarily due to a reduction in the redemption of coupons issued to support the product’s launch.

The addition of DAYTRANA, combined with the ADDERALL XR market share has helped Shire grow its total share of the US ADHD market to 28% at June 30, 2007 compared to 27% at June 30, 2006 (which included a 1% share relating to ADDERALL, which Shire subsequently divested).

PENTASA - Ulcerative colitis

PENTASA’s US average market share of the oral mesalamine prescription market remained stable at 17% for Q2 2007 compared to the same period in 2006. US prescriptions of PENTASA for the three months to June 30, 2007 were up 6% compared to the same period in 2006. This was primarily due to a 5% increase in the US oral mesalamine prescription market.

Sales of PENTASA for the three months to June 30, 2007 were US$40.2 million, an increase of 17% compared to the same period in 2006 (2006: US$34.5 million). Sales growth is higher than prescription growth primarily due to an increasing shift to the 500mg strength capsules as well as the impact of a price increase in November 2006.

LIALDA - Ulcerative colitis

In Q2 2007 LIALDA’s average market share of the US oral mesalamine prescription market was 2.5% following the launch of LIALDA in Q1 2007. Net sales of US$5.0 million for three months to June 30, 2007 were impacted by US$2.1 million in sales deductions, primarily stocking discounts and coupons.

The initial launch stock of US$34.3 million (before sales deductions) continues to be worked through the wholesaler pipeline. In accordance with US GAAP, sales of LIALDA are being recognized as the conditions for revenue recognition are met. All launch stock is expected to be recognized into revenue by the end of the year.

FOSRENOL - Hyperphosphatemia

In Europe, FOSRENOL has now been launched in Germany, France, UK, Italy and a number of other countries. Launches will continue throughout 2007 in the EU including Spain, subject to finalization of national marketing authorizations and the conclusion of pricing and reimbursement negotiations. European sales of FOSRENOL for the three months to June 30, 2007 were US$9.0 million (2006: US$0.3 million).

US sales of FOSRENOL for the three months to June 30, 2007 were US$15.5 million (2006: US$5.9 million) giving worldwide FOSRENOL sales of US$24.5 million for the quarter (2006: US$6.2 million). US IMS Retail Audit prescriptions for the three months to June 30, 2007 were up 10% compared to the same period in 2006 due to FOSRENOL increasing its average market share to 8.5% during Q2 2007 (2006: 8.1%) and market growth of 4% over the same period. The increase in net sales is significantly higher than retail audit prescription growth due to a combination of a price increase in July 2006, growth in use of the higher strengths (launched in early 2006), lower sales deductions, wholesaler de-stocking in 2006 of initial launch stocks and the growth of non-retail business.

REPLAGAL - Fabry disease

Sales for the three months to June 30, 2007 were US$31.9 million (2006: US$28.3 million). This increase of 13% is primarily due to higher unit sales in Europe and Canada and the impact of favorable exchange rates.

ELAPRASE - Hunter syndrome

ELAPRASE was successfully launched in the US in August 2006 and in several major European markets during the first half of 2007. ELAPRASE is now sold in 25 countries. Sales for the three months to June 30, 2007 were US$42.7 million compared to US$26.6 million in the first quarter of 2007, an increase of US$16.1 million.

CARBATROL - Epilepsy

US prescriptions for CARBATROL for the three months ending June 30, 2007 were down 4% compared to the same period in 2006. This was primarily due to a comparable decline in the US extended release carbamazepine prescription market.

Sales of CARBATROL for the three months to June 30, 2007 were US$17.9 million, an increase of 10% compared to the same period in 2006 (2006: US$16.2 million). Although there was a decrease in US prescriptions, sales rose due to price increases in July 2006 and April 2007.

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.

XAGRID - Thrombocythemia

Sales for the three months to June 30, 2007 were US$17.1 million, an increase of 21% compared to the same period in 2006 (2006: US$14.1 million). Expressed in transaction currencies (XAGRID is primarily sold in Euros), sales increased by 13% due to growth in many of Shire’s markets. In addition, there was an 8% benefit from favorable exchange rate movements against the US dollar.

3. Royalties

Royalty revenue increased to US$64.0 million for the three months to June 30, 2007 (2006: US$60.4 million).

Royalties from sales of 3TC for the three months to June 30, 2007 were US$39.0 million, an increase of 2% compared to the same period in 2006 (2006: US$38.3 million). The impact of foreign exchange movements has contributed 4% to the reported growth; excluding foreign exchange movements there has been a decline of 2% compared to the same period in 2006.
