    US GAAP operating income         $620 million    +51% $268 million   +39%
    Non GAAP diluted earnings per
    ADS                                     $3.49    -10%        $1.11    +9%
    US GAAP diluted earnings per
    ADS                                     $2.69   +214%        $0.94   +20%

These results include the effect of a change in best estimate of the
Medicaid rebate liability for ADDERALL XR, which increased fourth quarter
product sales by $98 million, and fourth quarter Non GAAP diluted earnings
per American Depositary Share ("ADS") by 32 cents. Product sales excluding
this change in best estimate would have been $2,596 million for the year to
December 31, 2009 and $679 million for the fourth quarter. Non GAAP diluted
earnings per ADS excluding this change in best estimate would have been $3.17
for the year to December 31, 2009 and 79 cents for the fourth quarter. For
further details see pages 9 to 10 and 26.

XR.

Angus Russell, Chief Executive Officer, commented:

"In this challenging and transformational year for Shire, I believe these
excellent results reflect the success of our focused strategy and business
model.

Strong fourth quarter sales growth of 36% from our core product
portfolio, supported by our increasing international reach, has contributed
significantly to our full year Non GAAP diluted earnings per ADS of $3.49.
Our recent decision to lower our best estimate of the Medicaid sales rebates
for ADDERALL XR contributed 32 cents to these earnings, which was not
previously anticipated in our guidance framework.

Our growth prospects remain excellent and our core product portfolio
currently has robust exclusivity protection. We have launched INTUNIV
successfully in the US, we plan to launch velaglucerase alfa (VPRIV)
imminently, and there is also an opportunity for REPLAGAL to enter the US
market. We have already seen encouraging signs for the future success of
these three products. REPLAGAL has increased its share in ex-US markets and
we expect this momentum to increase.

VYVANSE, our leading ADHD treatment with a current monthly US ADHD market
share of 13.6%, continues to grow and build strong brand recognition in the
US and has recently been launched in Canada. ADDERALL XR continues to
generate value from both product sales and a considerable royalty stream.

We have also demonstrated a pro-active approach to cost management in
2009 as promised, and have the opportunity to leverage our existing
infrastructure to deliver expanding margins in the future. We enter 2010 with
a strong balance sheet and excellent cash generation. This will allow us to
continue to expand our international presence and consider potential
acquisitions and in-licensing opportunities that fit our strategy.

We look forward to growing revenues and earnings in 2010 and re-iterate
our aspirational target of mid-teen revenue growth on average between 2009
and 2015."

    per ADS   $2.69         $0.80    $3.49    $0.86         $3.00    $3.86

These results include the effect of a change in best estimate of the
Medicaid rebate liability for ADDERALL XR, which increased product sales by
$98 million, and Non GAAP diluted earnings per ADS by 32 cents. Revenues and
Non GAAP diluted earnings per ADS excluding this change in best estimate for
the year to December 31, 2009 would have been $2,910 million and $3.17
respectively. For further details see pages 9-10 and 26.

The Non GAAP financial measures included in the tables above are
explained on pages 27 and 28, and are reconciled to the most directly
comparable financial measures prepared in accordance with US GAAP on pages 22
to 23 and 26 (full year) and pages 24 to 26 (Q4).

    - Product sales from core products were up 25% to $2,067 million (2008:
      $1,653 million). On a constant exchange rate ("CER") basis, which is a
      Non GAAP measure, core product sales were up 28% driven by continued
      strong growth from:

      - VYVANSE(R) (up 58% to $505 million, CER: up 58%);
      - LIALDA(R) / MEZAVANT(R) (up 68% to $236 million, CER: up 69%);
      - ELAPRASE(R) (up 16% to $353 million, CER: up 20%); and
      - REPLAGAL(R) (up 10% to $194 million, CER: up 16%).

    - Product sales including ADDERALL XR(R) were down 2% to $2,694 million
      (CER: 0%), due to the expected decline in ADDERALL XR product sales
      ($627 million, down 43% on 2008) following the launch of authorized
      generic versions by Teva Pharmaceuticals USA Inc. ("Teva") in April
      2009 and Impax Laboratories Inc. ("Impax") in October 2009, with the
      strong performance from Shire's core products (up 25%) offsetting the
      decrease in ADDERALL XR product sales.

    - Revenues for the year to December 31, 2009 decreased marginally to
      $3,008 million (2008: $3,022 million), as the 25% increase in core
      product sales and royalty income received on Teva and Impax's sales of
      authorized generic ADDERALL XR offset the decline in ADDERALL XR
      product sales.

    - Non GAAP operating income decreased by 7%, or $69 million, to $889
      million as a result of the marginally lower revenues and Shire's
      increased investment in research and development in 2009, which were
      partially offset by lower selling, general and administrative costs
      from Shire's continued focus on cost management. On a US GAAP basis,
      operating income in 2009 was $620 million, compared to $412 million in
      2008, an increase of 51% (2008 included in-process R&D ("IPR&D")
      charges of $263 million related to the acquisitions of Jerini AG
      ("Jerini") and METAZYM).

    - Non GAAP diluted earnings per ADS were down 10% to $3.49 (2008: $3.86).
      On a US GAAP basis diluted earnings per ADS increased to $2.69 compared
      to $0.86 in 2008, up 214% (earnings in 2008 were impacted by interest
      charges on the Transkaryotic Therapies Inc. ("TKT") appraisal rights
      settlement, IPR&D and other impairment charges, all of which reduced US
      GAAP diluted earnings per ADS in 2008).

    - Cash generation, which is a Non GAAP measure, in 2009 was $921 million
      (2008: $1,231 million), a decrease of $310 million. Cash generation was
      lower in 2009 due to lower net sales receipts following the
      genericization of ADDERALL XR. Cash generation in 2008 also included
      cash inflows from forward exchange contracts which were not repeated in
      2009.

2010 OUTLOOK

We enter 2010 with good momentum driven by the growth of our core product
portfolio. 2010 will also benefit from the change in best estimate for
ADDERALL XR rebates implemented in the fourth quarter of 2009 against a
background of further erosion of the brand and the impact of adverse business
mix trends.

In the first quarter of 2010 we expect our total revenues and Non GAAP
diluted earnings per ADS to be lower than the same period in 2009, which was
the last quarter before ADDERALL XR faced generic competition. For the
balance of the year Shire expects to generate both total revenue growth and
Non GAAP diluted earnings per ADS growth compared to 2009.

During 2010 we expect to see gross margins as a percentage of product
sales at a similar level to 2009. We will further increase our focused
investment in R&D and targeted investment will increase SG&A year on year. We
expect a Non GAAP effective tax rate in 2010 at a similar level to 2009.

We look forward to growing both total revenues and reported Non GAAP
diluted earnings per ADS in the full year 2010 compared to the excellent 2009
Non GAAP results and re-iterate our aspirational target of mid-teen revenue
growth on average between 2009 and 2015.

PRODUCT LAUNCHES

Subject to obtaining the relevant regulatory/governmental approvals,
product launches in 2010 will include:

    - VPRIV(TM) for the treatment of Gaucher disease in the US and
      EU;
    - REPLAGAL for the treatment of Fabry disease in the US;
    - MEZAVANT for the treatment of ulcerative colitis in certain
      EU and RoW countries;
    - FIRAZYR(R) for the symptomatic treatment of acute attacks of hereditary
      angiodema in certain European and Latin American countries;
    - EQUASYM(R) for the treatment of ADHD in certain EU
      countries; and
    - VYVANSE for the treatment of ADHD in Canada.

These results include the effect of a change in best estimate of the
Medicaid rebate liability for ADDERALL XR, which increased product sales by
$98 million, and Non GAAP diluted earnings per ADS by 32 cents. Revenues and
Non GAAP diluted earnings per ADS excluding this change in best estimate for
the fourth quarter would have been $795 million and 79 cents respectively.
For further details see pages 9 to 10 and 26.

The Non GAAP financial measures included above are explained on pages 27
and 28, and are reconciled to the most directly comparable financial measures
prepared in accordance with US GAAP on pages 24 to 26.

    - Product sales from core products were up 36% (CER: up 32%) to $585
      million (2008: $429 million) following continued growth from VYVANSE,
      LIALDA/MEZAVANT, ELAPRASE and REPLAGAL.

    - Product sales including ADDERALL XR, increased by 10% to $777 million
      (CER: up 8%). In Q4 2009 ADDERALL XR sales included the effect of a
      change in best estimate of the amount of Medicaid rebate payable on
      sales of ADDERALL XR. The effect of this change in best estimate
      increased ADDERALL XR net product sales for Q4 2009 by $98 million, of
      which $74 million related to product sales recognized in Q1 - Q3 2009.
      Q4 product sales, excluding the effect of the change in best estimate
      relating to product sales recognized in Q1 - Q3 2009, declined
      marginally to $703 million (2008: $704 million).

    - Revenues in Q4 2009 increased by 17% to $893 million (2008: $766
      million). The decline in ADDERALL XR product sales following
      genericization was more than offset by strong core product sales growth
      and royalty income on Impax's sales of authorized generic ADDERALL XR.

    - Non GAAP operating income increased by 30%, or $72 million, to $313
      million as the higher product sales and royalty income were only
      partially offset by increased investment in research and development.
      On a US GAAP basis operating income in Q4 2009 increased 39%, or $75
      million to $268 million (2008: $193 million).

    - Non GAAP diluted earnings per ADS for Q4 2009 were up 9% to $1.11 (Q4
      2008: $1.01). On a US GAAP basis diluted earnings per ADS were up 20%
      to $0.94 (2008: $0.78).

FOURTH QUARTER 2009 AND RECENT PRODUCT AND PIPELINE DEVELOPMENTS

Products

    VYVANSE - for the treatment of ADHD

    - On February 1, 2010 Shire announced the Canadian
      availability of VYVANSE (lisdexamfetamine dimesylate capsule), the
      first and only prodrug therapy approved for ADHD treatment in Canada.

    INTUNIV - for the treatment of ADHD in children and adolescents in the US

    - Once-daily INTUNIV became available in US pharmacies on
      November 9, 2009 and comes in four dosage strengths (1 mg, 2 mg, 3 mg,
      and 4 mg). INTUNIV is marketed in the US by the existing Shire ADHD
      sales team of nearly 600 representatives.

    - Revenue on the launch shipments of INTUNIV has been deferred
      and is being recognised in line with prescription demand. On this
      basis, INTUNIV achieved sales of $5.4 million from launch through
      December 31, 2009.

    DAYTRANA - for the treatment of ADHD in adolescents in the US

    - On December 4, 2009 and on January 29, 2010 Shire issued a
      voluntary recall of certain lots of DAYTRANA because some of the
      patches do not meet, or in future may not meet, their release liner
      removal specification, and as a result, patients and caregivers could
      have difficulty removing the liners. This action was not due to any
      safety issues and no interruption in product supply is anticipated.

    Pipeline

    VPRIV - for the treatment of Type 1 Gaucher disease

    - On November 24, 2009 Shire submitted a marketing authorization
      application to the European Medicines Agency ("EMEA") for VPRIV,
      Shire's enzyme replacement therapy in development for the treatment of
      Type 1 Gaucher disease. The submission has been granted an accelerated
      review by EMEA. Submissions have also been made in the US on September
      1, 2009 and Canada on October 20, 2009. In the U.S., the application is
      being reviewed by the US Food and Drug Administration ("FDA") under
      Priority Review with a Prescription Drug User Fee Act action date of
      February 28, 2010. The FDA recently completed pre-approval inspections
      of Shire's Massachusetts facilities for the manufacturing and testing
      of VPRIV. These inspections were an important milestone in the review
      and approval process for the VPRIV New Drug Application.

    - VPRIV is available ahead of its commercial launch in the US via an
      FDA-accepted treatment protocol and elsewhere on a pre-approval basis
      using the fastest mechanisms available in each country, in response to
      the ongoing shortage of a currently marketed treatment for Type 1
      Gaucher disease.

    - Pending FDA approval, Shire intends to price the VPRIV 400 Unit vial at
      a wholesale acquisition cost ("WAC") of $1,350 in the US.

    - We are pleased to announce enhancements to our OnePathSM Access
      program. In addition to our existing patient assistance programs and
      our support of patient associations, Shire will provide direct co-pay
      assistance, covering the first 3 months of out-of-pocket prescription
      costs for eligible US patients this year. In 2011, we also plan to cap
      the out-of-pocket prescription costs for these patients at $500. This
      new program will be effective March 1, 2010 for eligible ELAPRASE
      patients and VPRIV patients pending FDA approval.

    VYVANSE - for the treatment of ADHD

    - On December 21, 2009 a supplemental New Drug Submission for VYVANSE was
      submitted in Canada for the extension of the indication to adolescents
      and adults with ADHD.

    - On January 14, 2010 a supplemental New Drug Application for VYVANSE was
      submitted to the FDA for the extension of the indication to adolescents
      aged 13 to 17 years with ADHD.

    REPLAGAL - for the treatment of Fabry disease

    - On December 22, 2009 Shire submitted a Biologics License Application to
      the FDA for REPLAGAL, its enzyme replacement therapy for Fabry disease.
      Shire has worked closely with the FDA to establish an early access
      program in response to the ongoing shortage of the currently marketed
      treatment for Fabry disease in the US. REPLAGAL is currently available
      to Fabry patients in the US under an FDA-approved treatment protocol,
      and Shire is also supporting emergency Investigational New Drug
      requests. REPLAGAL first received marketing authorization in the
      European Union in 2001, and is approved for the treatment of Fabry
      disease in 45 countries. Shire expects its REPLAGAL supply to be
      adequate to meet anticipated global demand.

    OTHER FOURTH QUARTER AND RECENT DEVELOPMENTS

    - On December 23, 2009 Shire completed the purchase of the remaining
      Jerini shares from the minority shareholders, and now owns 100% of
      Jerini.

    - On February 24, 2009 Actavis Elizabeth LLC brought a lawsuit against
      the FDA seeking to overturn the FDA's decision granting new chemical
      entity exclusivity to VYVANSE. Shire has intervened in the lawsuit. On
      October 23, 2009, following a period for public comment, the FDA issued
      a letter setting forth its analysis of the legal and regulatory issues
      and reaffirming its decision that VYVANSE is entitled to new chemical
      entity exclusivity. A hearing on cross-motions for summary judgment
      was held on February 17, 2010. No rulings on the cross-motions were made
      at the hearing.

    - On December 2, 2009 Shire announced that it had settled the litigation
      with Teva over Shire's supply to Teva of an authorized generic version
      of ADDERALL XR. Shire has been supplying Teva with authorized generic
      ADDERALL XR since April 1, 2009. Shire's ability to supply the product
      had been limited by restrictions that the US Drug Enforcement
      Administration ("DEA") places on amphetamine, which is the product's
      active ingredient. Teva filed suit claiming that Shire was in breach of
      its supply contract. After the lawsuit was filed, the DEA granted
      Shire additional quota for 2009, allowing Shire to supply Teva with
      additional product. Teva dismissed its lawsuit, including its claims for
      monetary damages, specific performance and other equitable relief. No
      consideration was exchanged by the parties as part of the settlement.

DIVIDEND

For the six months to December 31, 2009 the Board has resolved to pay an
interim dividend of 9.250 US cents per ordinary share (2008: 7.761 US cents
per ordinary share).

Dividend payments will be made in Pounds Sterling to ordinary
shareholders and in US Dollars to holders of American Depository Shares. A
dividend of 5.910 pence per ordinary share (2008: 5.469 pence) and 27.750 US
cents per ADS (2008: 23.283 US cents) will be paid on April 14, 2010 to
persons whose names appear on the register of members of the Company at the
close of business on March 12, 2010.

Together with the first interim payment of 2.147 US cents per ordinary
share (2008: 2.147 US cents per ordinary share), this represents total
dividends for 2009 of 11.397 US cents per ordinary share (2008: 9.908 US
cents per ordinary share), an increase of 15% in US Dollar terms over 2008.

BOARD CHANGES

On December 23, 2009 Dr Michael Rosenblatt stepped down from
the Shire Board as a non-executive director, following Dr Rosenblatt's
appointment as Executive Vice President and Chief Medical Officer at Merck &
Co., Inc. Matt Emmens, Chairman of Shire said "On behalf of the Shire Board,
I would like to thank Michael for his contributions and we wish him well in
his new position".

Dr Barry Price retired from the Shire Board as a non-executive
director upon the completion of his term of office on January 24, 2010. Matt
Emmens
, Chairman of Shire said "On behalf of the Shire Board, I would like to
thank Barry for his significant contributions over the past 14 years. Barry
brought a wealth of expertise and experience to the Board and we wish him
well for the future".

Core Products

VYVANSE - ADHD

The increase in VYVANSE product sales was driven by higher US
prescription demand versus 2008, 9% growth in the US ADHD market and price
increases. Product sales growth was lower than prescription growth due to
lower stocking in 2009 compared to 2008.

ELAPRASE - Hunter syndrome

The growth in sales of ELAPRASE was driven by increased
volumes across all regions where ELAPRASE is sold. On a CER basis sales grew
by 20% (66% of ELAPRASE sales are made outside of the US).

LIALDA/MEZAVANT - Ulcerative colitis

Strong product sales of LIALDA/MEZAVANT continued in the year to December
31, 2009
driven by an increase in market share over 2008, growth in the US
oral mesalamine market and price increases taken during 2009.

PENTASA - Ulcerative colitis

Product sales of PENTASA continued to grow despite a decrease in US
prescription demand in 2009 compared to 2008 due to the impact of price
increases taken during 2009.

REPLAGAL - Fabry disease

The growth in REPLAGAL product sales in 2009 over 2008 was
driven by a significant increase in demand in the fourth quarter of 2009 due
to an acceleration of patients switching to REPLAGAL in the EU, attributable
in part to supply shortages of a competitor product. Sales increased 16% on a
CER basis (REPLAGAL is sold primarily in Euros and Pounds sterling).

FOSRENOL - Hyperphosphatemia

Product sales increased as FOSRENOL entered new countries and grew in
existing markets outside the US. In the US, FOSRENOL sales grew despite lower
prescriptions due to a price increase in 2009.

INTUNIV - ADHD

INTUNIV was launched in the US in November 2009. In line with
Shire's revenue recognition policy for launch shipments, initial stocking
shipments have been deferred and are being recognised into revenue in line
with end-user prescription demand. At December 31, 2009 deferred revenues on
the balance sheet represented gross sales of $38.8 million.

Other products

ADDERALL XR - ADHD

The launch by Teva and Impax of their authorised generic versions of
ADDERALL XR led to the expected decline in 2009 of branded ADDERALL XR
prescription demand, and resulted in higher US sales deductions in 2009
compared to 2008. These factors more than offset the positive impacts of
price increases taken since the fourth quarter of 2008, and the inclusion in
product sales of shipments of authorized generic ADDERALL XR to Teva and
Impax in 2009.

Sales deductions represented 47% of branded ADDERALL XR gross sales in
the year to December 31, 2009 compared to 25% in the same period in 2008,
following higher Medicaid and Managed Care rebates subsequent to the
authorized generic launches.

There are potentially different interpretations as to how
shipments of authorized generic ADDERALL XR to Teva and Impax should be
included in the Medicaid rebate calculation pursuant to Medicaid rebate
legislation, including the Deficit Reduction Act of 2005 ("Medicaid rebate
legislation"). As a result more than one unit rebate amount ("URA") is
calculable for the purpose of determining Shire's Medicaid rebate liability
to States after the authorized generic launch. During 2009 Shire highlighted
the different interpretations to the Centers for Medicare and Medicaid
Services, ("CMS") and submitted data to the CMS for the purpose of computing
the URA, based on Shire's reasonable interpretation of the Medicaid rebate
legislation and related guidance. The State Medicaid agencies have invoiced
Shire for Medicaid rebates, and Shire has paid these Medicaid rebate
invoices, based on this URA. Despite this CMS has the ability to subsequently
challenge Shire's interpretation of the Medicaid rebate legislation, and
require an alternative interpretation to be applied (both retrospectively and
prospectively), which could result in a significantly higher Medicaid
liability.

Throughout 2009 Shire's management has recorded its accrual
for Medicaid rebates based on its best estimate of the rebate payable. For
the first three quarters of 2009, Shire's management based this best estimate
on an amount that Shire could pay were CMS to challenge Shire's
interpretation and require an alternative interpretation of the Medicaid
rebate legislation to be applied. In the fourth quarter of 2009, Shire's
management lowered its best estimate of the Medicaid rebate payable down to
be consistent with (i) Shire's interpretation of the Medicaid rebate
legislation, (ii) Shire's repeated and consistent submission of price
reporting to CMS using Shire's interpretation of the Medicaid rebate
legislation, (iii) CMS calculating the URA based on that interpretation, (iv)
States submitting Medicaid rebate invoices using this URA, and (v) Shire
paying these invoices. This change of estimate increased ADDERALL XR product
sales by $97.7 million in the fourth quarter of 2009 (of which $73.6 million
related to ADDERALL XR product sales recognized in Q1-Q3 2009).

In determining its best estimate of the Medicaid rebate liability at
December 31, 2009 Shire's management has considered a number of factors taken
in combination (including the receipt of a further quarter's invoices from
the States with a URA based on Shire's interpretation of the Medicaid rebate
legislation and related guidance, and Shire's likely response were CMS to
employ an alternative interpretation of the Medicaid rebate legislation). Any
future change in Shire's interpretation which results in a change of estimate
could significantly decrease sales of ADDERALL XR in the period of any such
change in estimate.

Shire strongly believes that its interpretation of the Medicaid rebate
legislation is reasonable and correct. However, CMS could disagree with
Shire's interpretation, and require Shire to apply an alternative
interpretation of the Medicaid rebate legislation and pay up to $210 million
above the recorded liability. This would represent a URA substantially in
excess of the unit sales price of ADDERALL XR and accordingly be in excess of
the approximate amount of the full cost to the States of reimbursement for
Medicaid prescriptions of ADDERALL XR. Should CMS take such an approach,
Shire could seek to limit any additional payments to a level approximating
the full, un-rebated cost to the States of ADDERALL XR, or $98 million above
the recorded liability. Further, Shire believes it has a strong legal basis
supporting its interpretation of the Medicaid rebate legislation, and that
there would be a strong basis to initiate litigation to recover any amount
paid in excess of its recorded liability. The result of any such litigation
cannot be predicted and could result in additional rebate liability above
Shire's current best estimate.

Shire receives royalties from GlaxoSmithKline ("GSK") on
worldwide sales of 3TC and ZEFFIX which have decreased mainly due to
competition from other treatments.

Royalties were received on Teva's sales of an authorized
generic version of ADDERALL XR between April and September 2009, and on
Impax's sales of its authorized generic version of ADDERALL XR from October
2009
.

Other royalties are received primarily on worldwide (excluding
UK and Republic of Ireland) sales of REMINYL(R) and REMINYL(R) XL (known as
RAZADYNE(R) and RAZADYNE(R) ER in the US). Royalties on sales of these
products decreased in 2009 to $47.7 million (2008: $63.5 million) due to
generic competition in the US from August 2008.

    sales

Non GAAP cost of product sales as a percentage of product sales increased
in 2009 due to changes to the product mix following the launch of authorized
generic versions of ADDERALL XR by Teva and Impax. Higher deductions on
Shire's sales of branded ADDERALL XR, together with lower margins on sales of
the authorized generic version to Teva and Impax have both depressed gross
margins.

Non GAAP R&D increased 10% in 2009 compared to 2008 as Shire has
continued to increase investment in R&D programs, due in part to an
acceleration of investment in VPRIV and REPLAGAL in the US.

million
(2008: $20.7 million) from the sale of non-core products to
Laboratorios Almirall S.A. in 2007. These gains had been deferred since 2007
pending obtaining the relevant consents to transfer certain assets.

IPR&D

For the year to December 31, 2009, Shire recorded IPR&D charges of $1.6
million
(2008: $128.1 million) relating to FIRAZYR in markets outside of the
EU. In 2008 IPR&D also included a charge of $135.0 million relating to the
acquisition of METAZYM from Zymenex A/S.

Reorganization costs

For the year to December 31, 2009 Shire recorded
reorganization costs of $12.7 million (2008: $nil) relating to the transfer
of manufacturing from its Owings Mills facility.

million
(2008: $25.5 million), primarily earned on cash and cash equivalents.
Interest income for the year to December 31, 2009 is lower than the same
period in 2008 due to significantly lower interest rates in 2009 compared to
2008, and lower average cash and cash equivalent balances throughout the
year.

$39.8 million (2008: $139.0 million), including interest expense on Shire's
convertible bond of $33.6 million (2008: $33.6 million). Interest expense in
2008 was higher than 2009 due to interest expense of $87.3 million recorded
in respect of the TKT appraisal rights litigation, of which $73.0 million was
additional interest arising from the settlement of the litigation in November
2008
.

Non GAAP other income, net in 2009 included a gain of $5.7 million on
substantial modification of a property lease. In 2008 Non GAAP other income,
net primarily related to foreign exchange gains.

Taxation

The effective rate of tax for the year to December 31, 2009 was 22%
(2008: 37%). Excluding the impact of IPR&D charges of $263.1 million in 2008,
which are either not tax deductable or for which no tax benefit is currently
recognised, the effective rate of tax for 2008 was 19%. The effective tax
rate on Non GAAP income is 25% (2008: 23%).

The Non GAAP effective rate of tax in 2009 is higher than 2008 due to
increased profits in higher tax territories, together with the recognition of
valuation allowances against certain EU and US deferred tax assets. These
factors more than offset reductions to the Non GAAP effective rate of tax
from the decrease in valuation allowances held in respect of US State tax
credits and losses. In addition, the effect of the change in best estimate of
ADDERALL XR Medicaid rebates increased the Non GAAP effective rate of tax by
one percentage point in 2009.

Discontinued operations

The loss from discontinued operations for the year to December 31, 2009
was $12.4 million (2008: $17.6 million), relating to net losses on
discontinued Jerini businesses which were either divested or closed during
2009.

(1) For the three and twelve month periods ended December 31,
2009
and 2008, 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 month periods ended December 31, 2009 and
2008 the ordinary shares underlying the convertible bonds have not been
included in the calculation of the diluted weighted average number of shares,
because the effect of their inclusion would be anti-dilutive.

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, human genetic therapies and gastrointestinal diseases as well as
opportunities in other therapeutic areas to the extent they arise through
acquisitions. Shire's in-licensing, merger and acquisition efforts are
focused on products in specialist markets with strong intellectual property
protection and global rights. Shire believes that a carefully selected and
balanced portfolio of products with strategically aligned and relatively
small-scale sales forces will deliver strong results.

THE "SAFE HARBOR" STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION
REFORM ACT OF 1995

Statements included herein that are not historical facts 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, risks associated with: the inherent uncertainty of research,
development, approval, reimbursement, manufacturing and commercialization of
Shire's Specialty Pharmaceutical and Human Genetic Therapies products, as
well as the ability to secure and integrate new products for
commercialization and/or development; government regulation of Shire's
products; Shire's ability to manufacture its products in sufficient
quantities to meet demand; the impact of competitive therapies on Shire's
products; Shire's ability to register, maintain and enforce patents and other
intellectual property rights relating to its products; Shire's ability to
obtain and maintain government and other third-party reimbursement for its
products; and other risks and uncertainties detailed from time to time in
Shire's filings with the Securities and Exchange Commission.

Non GAAP Measures

This press release 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 from continuing
operations before income taxes and earnings of equity method investees
("Effective tax rate on Non GAAP income"); Non GAAP Cost of product sales;
Non GAAP Research and development; Non GAAP Selling, general and
administrative; Non GAAP operating expenses; Non GAAP interest expense; Non
GAAP other income; and Non GAAP cash generation. 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.

These Non GAAP financial measures are used by Shire's management to make
operating decisions because they facilitate internal comparisons of Shire's
performance to historical results and to competitors' results. 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 measures are presented in this press release as Shire's
management believe that they will provide investors with a means of
evaluating, and an understanding of how Shire's management evaluates, Shire'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
Shire'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.

The following items, including their tax effect, have been excluded from
both 2008 and 2009 Non GAAP earnings, and from our 2010 outlook:

Amortization and asset impairments:

    - Intangible asset amortization and impairment charges; and

    - Other than temporary impairment of investments.

    Acquisitions and integration activities:

    - Upfront payments and milestones in respect of in-licensed and acquired
      products;

    - Costs associated with acquisitions, including transaction costs, and
      fair value adjustments on contingent consideration and acquired
      inventory;

    - Costs associated with the integration of companies; and

    - Incremental interest charges arising on the settlement of litigation
      with the former dissenting shareholders of TKT.

    Divestments, re-organizations and discontinued operations

    - Gains and losses on the sale of non-core assets;

    - Costs associated with restructuring and re-organization activities;

    - Termination costs;

    - Costs associated with the introduction of the new holding company; and

    - Income / (losses) from discontinued operations.

Depreciation, which is included in Cost of product sales, Research and
development and Selling, general and administrative costs in our US GAAP
results, has been separately disclosed for the presentation of 2008 and 2009
Non GAAP earnings. A reconciliation of Non GAAP financial measures to the
most directly comparable measure under US GAAP is presented on pages 22-26.

Sales growth at CER, which is a Non GAAP measure, is computed by
restating 2009 results using average 2008 foreign exchange rates for the
relevant period.

Average exchange rates for the year to December 31, 2009 were
$1.57:GBP1.00 and $1.39:EUR1.00 (2008: $1.85:GBP1.00 and $1.47:EUR1.00).

Average exchange rates for Q4 2009 were $1.63:GBP1.00 and $1.48:EUR1.00
(2008: $1.57:GBP1.00 and $1.32:EUR1.00).

2008 BALANCE SHEET RESTATEMENT

The consolidated financial information at December 31, 2008
has been restated. The effect of this restatement was to reduce Shire's
non-current deferred tax liabilities and decrease Shire's accumulated deficit
by $29 million. The restatement does not affect Shire's net income or cash
flows for the years and quarters ended December 31, 2009 and 2008.
