DUBLIN, August 4, 2010 - Shire plc (LSE: SHP, NASDAQ: SHPGY) the global specialty
biopharmaceutical company, announces results for the three months to June 30,
2010
.

    Financial Highlights                    Q2 2010(1)

    Product sales                          $764 million      +37%

    Product sales from core products(2)    $684 million      +39%
    Product sales from core products on
    a CER basis(3)                                           +42%

    Total revenues                         $849 million      +35%

    Non GAAP operating income              $270 million     +134%

    US GAAP operating income               $224 million     +547%
    Non GAAP diluted earnings per ADS     $1.03              +71%
    US GAAP diluted earnings per ADS      $0.86             +253%

(1) Percentages compare to equivalent 2009 period.

(2) Core products represent Shire's products excluding ADDERALL XR.

(3) Sales growth at CER is computed by restating 2010 results
using average 2009 foreign exchange rates.

Angus Russell, Chief Executive Officer, commented:

"This was another excellent quarter with strong performance from core
product sales, up 39%, driving increases in operating income and earnings per
ADS. Shire is performing well on all fronts.

In ADHD, sales of VYVANSE are up 30% and clinical trial enrolment has
progressed for the European program and for the new indication proof of
concept studies. Marketing authorization was recently given for VYVANSE in
Brazil, our first approval for this product outside North America, and the
launch is being planned for mid 2011. INTUNIV continues to build share with
child and adolescent psychiatrists and we recently filed an sNDA for its
adjunctive use with long-acting oral stimulants for the treatment of ADHD.

Sales of our Fabry treatment, REPLAGAL are up 84%, and we've seen very
rapid uptake of VPRIV in the Gaucher market place with approximately 850
patients now treated globally. We received a positive opinion for VPRIV from
the Committee for Medicinal Products for Human Use and although we already
have sales on a preapproved basis, the anticipated European Commission
decision later this year will enable the product's commercial roll out.

LIALDA for ulcerative colitis is also performing well with sales up 27%
and a US market share approaching 19%. Phase 3 clinical trials investigating
the use of the product for the treatment of diverticular disease are
progressing.

With cash generation of $416 million during the quarter and excellent
growth prospects ahead, we continue to invest in our marketed products, our
pipeline and our international presence.

This year, the pharmaceutical sector has faced the challenges of US
healthcare reform, European pricing pressures and fluctuating foreign
exchange levels. Shire is, however, well placed to absorb these macro
factors. Our strong performance in the second quarter reinforces our
confidence in growing both revenue and earnings in the full year 2010
compared to 2009 and we now see Non GAAP earnings trending towards $4.00 per
ADS for the full year. This includes the financial effect of the proposed
acquisition of Movetis NV. We also re-iterate our aspirational target of
mid-teens sales growth on average between 2009 and 2015."

FINANCIAL SUMMARY

Second Quarter 2010 Unaudited Results

The Non GAAP financial measures included within this release are
explained on page 25, and are reconciled to the most directly comparable
financial measures prepared in accordance with US GAAP on pages 20 - 23.

    - Product sales were up 37% to $764 million (2009: $558 million) with
      growth from both core products (up 39% to $684 million) and
      ADDERALL XR(R)(up 19% to $80 million). On a constant exchange rate
      ("CER") basis, which is a Non GAAP measure, core product sales were up
      42%.

    - The continued growth in core product sales was the result of strong
      performance across the portfolio:

           - VYVANSE(R) (up 30% to $148 million, CER: up 29%);
           - ELAPRASE(R) (up 17% to $100 million, CER: up 20%);
           - REPLAGAL(R) (up 84% to $82 million, CER: up 93%);
           - LIALDA(R)/MEZAVANT(R) (up 27% to $70 million, CER: up 27%); and

    - Recently launched INTUNIV(R) ($51 million) and VPRIV(R) ($29 million).

    - Total revenues were up 35% (CER: up 37%) to $849 million (2009: $630
      million), as a result of both increased product sales and higher
      royalties (up 24% due to higher royalty income on sales of authorized
      generic ADDERALL XR).

    - Non GAAP operating income increased by $154 million, or 134%, to $270
      million (2009: $116 million) due to the higher total revenues and
      improved operating expense ratios compared to 2009, despite increased
      investment in research and development ("R&D") programs and selling,
      general and administrative ("SG&A") costs in support of recent growth.
      On a US GAAP basis, operating income increased by $189 million, or
      547%, to $224 million (2009: $35 million).

    - Cash generation, which is a Non GAAP measure, increased by $224 million
      to $416 million (2009: $192 million) following higher cash receipts
      from product sales and royalties, cash inflows from forward foreign
      exchange contracts in 2010 compared to outflows in 2009, partially
      offset by higher cash payments on the increased investment in R&D
      and SG&A.

    - Net debt at June 30, 2010 was $398 million (December 31, 2009: $615
      million), a reduction of $217 million in 2010. The reduction in net
      debt was driven by strong cash generation of $694 million in the first
      half of 2010, which was partially used in the acquisition of and
      construction at Lexington Technology Park, cash taxes and the
      dividend payment.

DIVIDEND

Dividend payments will be made in Pounds Sterling to Ordinary
shareholders and in US Dollars to holders of American Depositary Shares
("ADS"). A dividend of 1.410 pence per ordinary share (an increase of 8%
compared to 2009: 1.302 pence) and 6.750 US cents per ADS (an increase of 5%
compared to 2009: 6.441 US cents) will be paid on October 7, 2010 to persons
whose names appear on the register of members of the Company at the close of
business on September 10, 2010.

2010 OUTLOOK

Given our strong performance in the second quarter, we now see Non GAAP
earnings trending towards $4.00 per ADS, a 15% increase on 2009. This
includes the financial effect of the proposed acquisition of Movetis NV.

The accelerated growth in the first half has increased our confidence in
growing both revenues and earnings for the full year 2010 compared to 2009,
despite the backdrop of the cumulative impact of US healthcare reform,
pressure on European pricing and increasingly adverse foreign exchange rates.

Our core portfolio will continue to deliver strong year on year growth in
2010. The relative growth rate in the second half will start to moderate as
we compare against tougher comparatives in 2009 and the rate of sales growth
of REPLAGAL will also moderate as the continuing increase in patients being
treated by REPLAGAL will be supported, in part, by product shipped in the
second quarter.

Revenues both from ADDERALL XR product sales and from total royalties are
anticipated to be lower in the last two quarters of 2010 compared to their
very strong performance in the first half.

Given the strong performance in the first half and our confidence in our
outlook, we will continue to make targeted increases in 2010 and beyond in
investment in our international infrastructure, our recent product launches
and in progressing our pipeline to support longer term growth. As a result,
combined R&D and SG&A spending in 2010 will be at the top end of our previous
guidance of 5-10% growth year on year.

PRODUCT LAUNCHES

Subject to obtaining the relevant regulatory/governmental approvals,
future product launches in the next 12 months include:

    - VPRIV for the treatment of Type 1 Gaucher disease in the
      European Union ("EU");

    - 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 ("HAE") in certain European and Latin American countries;

    - EQUASYM(R) for the treatment of Attention Deficit
      Hyperactivity Disorder ("ADHD") in certain EU countries; and

    - VYVANSE (VENVANSE) for the treatment of ADHD in children in Brazil.

    PRODUCT AND PIPELINE DEVELOPMENTS

    Products

    VYVANSE - for the treatment of ADHD

    - On May 4, 2010 the US Food and Drug Administration ("FDA")
    approved a change to the prescribing information for the once-daily ADHD
    treatment VYVANSE to include supplemental data demonstrating significant
    improvement in attention in adults with ADHD across all six assessments
    conducted at 2, 4, 8, 10, 12 and 14 hours after administration as
    measured by average Permanent Product Measure of Performance total
    scores, as well as at each time point measured. VYVANSE is now the first
    and only oral ADHD long-acting stimulant treatment to have efficacy data
    at 14 hours post-dose for adult patients included in its product
    labeling.

    - On July 5, 2010 ANVISA, the Brazilian health authority, granted
    approval of the Marketing Authorization Application for the product under
    the trade name VENVANSE for the treatment of ADHD in children aged 6 to
    12. This represents the first approval of lisdexamfetamine dimesylate in
    Latin America.

    LIALDA/MEZAVANT - for the treatment of ulcerative colitis

    - On July 8, 2010 Shire announced that it had filed a lawsuit in the
    U.S. District Court for the District of Delaware against Cadila
    Healthcare Limited, doing business as Zydus Cadila and Zydus
    Pharmaceuticals (USA), Inc. (collectively, "Zydus") for the infringement
    of U.S. Patent No. 6,773,720 (the '720 patent). The lawsuit was filed as
    a result of an Abbreviated New Drug Application ("ANDA") filed by Zydus
    seeking FDA approval to market and sell generic versions of LIALDA prior
    to the expiration of the '720 patent.

    DAYTRANA - for the treatment of ADHD

    - On July 6, 2010 Shire announced the FDA approval of DAYTRANA for the
    treatment of ADHD in adolescents aged 13 to 17 years. DAYTRANA, the
    first and only transdermal ADHD patch, is already an FDA-approved ADHD
    treatment for children aged 6 to 12 years.

    REPLAGAL - for the treatment of Fabry disease

    - REPLAGAL is experiencing significant demand globally and is now the
    market leader in many key regions, due principally to a competitor's
    ongoing supply disruption. Currently there are approximately 2,000
    patients worldwide being treated with REPLAGAL and Shire has capacity
    to add 150-250 more patients in 2010. Shire anticipates that it could
    add 250-350 more patients phased throughout 2011. Shire's continuing
    priority is to ensure the long term, uninterrupted supply to patients
    currently being treated with REPLAGAL and we will continue to monitor
    demand and manage supply carefully.

    - Shire initiated a rolling submission of a REPLAGAL Biologics License
    Application ("BLA") in March 2010. On August 3, 2010 Shire informed the
    FDA that it would not complete the rolling submission and withdrew its
    BLA in order to consider updating the submission with additional clinical
    data.

    VPRIV - for the treatment of Type 1 Gaucher disease

    - On June 25, 2010 Shire received a positive opinion from the Committee
    for Medicinal Products for Human Use ("CHMP") of the European Medicines
    Agency ("EMA") on the marketing authorization for VPRIV, its enzyme
    replacement therapy ("ERT") for the Treatment of Type 1 Gaucher Disease
    in the EU. The CHMP positive opinion will now be forwarded to the
    European Commission for ratification. In addition to the CHMP positive
    opinion, VPRIV has received orphan drug designation from the Committee
    for Orphan Medicinal Products. In many European countries patients have
    been receiving VPRIV on an early access basis, developed in partnership
    with national and regional authorities.

With the accelerated adoption of VPRIV worldwide, and the earlier than
anticipated US approval and EU positive opinion, Shire expects continued high
demand and currently has approximately 850 patients on therapy, with capacity
to support approximately 1,000 patients in 2010. As a result, Shire is now
implementing a program with physicians and patients to monitor demand and
manage requests from new patients carefully in order to ensure long-term,
uninterrupted treatment with VPRIV.

Pipeline

HGT-1410 for Sanfilippo Syndrome

    - HGT-1410 is in development as an ERT for the treatment of Sanfilippo
    Syndrome, a lysosomal storage disorder. The product has been granted
    orphan drug designation in the US and in the EU. Shire initiated a Phase
    1/2 clinical trial in August 2010.

    Guanfacine CarrierWave (GCW; SPD 547)

    - SPD 547 is in early stage development for the treatment of ADHD. A
    feasibility study in humans using microdosing has been completed and
    results indicate characteristics suitable for entering formal Phase 1
    trials. The Phase 1 program is expected to be initiated in Q3 2010 with
    results throughout 2011. GCW could potentially improve on the current
    guanfacine profile to minimize known food, gastrointestinal ("GI") and
    sedation effects.

    OTHER SECOND QUARTER AND RECENT DEVELOPMENTS

    Proposed acquisition of Movetis NV

    - On August 3, 2010 Shire announced that it was launching a voluntary
    public takeover offer for all the shares in Movetis NV ("Movetis"), the
    Belgium-based European specialty GI company, for a fully diluted equity
    purchase price of EUR428 million. Movetis' board unanimously supports the
    transaction and Institutional shareholders holding 38.9% of Movetis'
    shares have unconditionally agreed to accept the offer. It is anticipated
    that the takeover offer, which is contingent upon the fulfilment of
    certain conditions, will open for acceptance in September.

This proposed acquisition will significantly broaden Shire's global GI
portfolio and adds growing revenues from RESOLOR(R) (prucalopride), a new
chemical entity indicated for the symptomatic treatment of chronic
constipation in women in whom laxatives fail to provide adequate relief.
Movetis has the rights to RESOLOR in the EU, Iceland, Lichtenstein, Norway
and Switzerland and is entitled to royalties on sales of RESOLOR outside of
Europe from Johnson & Johnson.

The acquisition also brings to Shire world-class research and development
talent and a promising GI pipeline.

Purchase of Lexington Technology Park

    - On June 30, 2010 Shire purchased Lexington Technology Park in
    Lexington, Massachusetts for a cash purchase price of $165 million. The
    purchase underlines our investment in the growth of Shire's Human Genetic
    Therapies business, and gives Shire the ownership of an additional
    570,000 square feet of expansion potential available under the current
    permit, including 170,000 square feet already under construction.

BOARD CHANGES

On June 16, 2010 Dr David Ginsburg and Ms Anne Minto OBE were
appointed to Shire's Board of Directors with immediate effect. Dr Ginsburg
was also appointed to Shire's Science & Technology Committee. Ms Minto was
appointed to Shire's Remuneration Committee and assumed the Chair of that
Committee on the retirement of Ms Kate Nealon from the Shire Board at the end
of Ms Nealon's term of office on July 26, 2010.

ending June 25, 2010.

(2) IMS NPA Data not available.

(3) Not sold in the US in Q2 2010.

VYVANSE - ADHD

The increase in VYVANSE product sales was driven by higher US
prescription demand, price increases taken since Q2 2009 and the launch of
the product in Canada during 2010, partially offset by higher sales
deductions principally due to US Healthcare Reform.

ELAPRASE - Hunter syndrome

The growth in sales of ELAPRASE was driven by increased
volumes across all regions in which ELAPRASE is sold. On a CER basis sales
grew by 20% (77% of ELAPRASE sales are made outside of the US).

REPLAGAL - Fabry disease

The growth in REPLAGAL product sales was driven by an increase
in demand due to an acceleration of patients switching to REPLAGAL in the EU,
principally due to the disruption to supply of a competitor product. The
growth was, in part, attributable to sales of products that will be used for
the treatment of patients in the second half of 2010. Sales increased 93% on
a CER basis (REPLAGAL is sold primarily in Euros and Pounds sterling).

LIALDA/MEZAVANT - Ulcerative colitis

Product sales growth for LIALDA/MEZAVANT continued in Q2 2010, driven by
increased US prescription demand and price increases, partially offset by
higher sales deductions. The US oral mesalamine market was broadly flat year
on year.

PENTASA - Ulcerative colitis

Product sales of PENTASA increased due to price increases taken since Q2
2009, which more than offset lower US prescription demand.

INTUNIV - ADHD

Product sales of INTUNIV included both revenue from initial
stocking shipments in 2009, which were deferred in accordance with Shire's
accounting policy, and shipments made during Q2 2010. At June 30, 2010 all
initial stocking shipments have been recognised as revenue and no deferred
revenue remains.

FOSRENOL - Hyperphosphatemia

Product sales of FOSRENOL in the EU decreased primarily due to mandatory
price reductions taken in 2010. Product sales of FOSRENOL in the US decreased
due to lower US prescription demand and higher sales deductions in Q2 2010
compared to 2009, which more than offset the effect of price increases taken
since Q2 2009.

VPRIV - Gaucher disease

Product sales in the US were generated on an approved basis
after February 26, 2010 when approval was received from the FDA, and in the
EU on a pre-approval basis via patient early access programs.

FIRAZYR - HAE

The product sales growth was driven by increased volumes
across markets in Europe. FIRAZYR is the first new product for HAE in Europe
in 30 years and has orphan exclusivity for acute attacks of HAE in adults in
the EU until 2018.

ADDERALL XR - ADHD

Product sales increased despite a decline in US prescription demand due
primarily to the effects of product stocking and price increases taken since
Q2 2009. Stocking was $33 million (gross sales equivalent) in Q2 2010
compared to the significant destocking in Q2 2009 ($76 million gross sales
equivalent) following the launch of an authorized generic version of ADDERALL
XR in April 2009.

2. Royalties

Royalty income increased by 24% due to higher royalties
received on sales of authorized generic versions of ADDERALL XR (royalties in
Q2 2010 were received from Impax Laboratories Inc. ("Impax"), and in Q2 2009
were received from Teva Pharmaceuticals Industries Ltd) and higher other
royalties principally on sales of FOSRENOL in Japan. Royalties received for
3TC and Zeffix from GlaxoSmithKline ("GSK") were lower in 2010 compared to
2009 as 3TC royalties were adversely impacted by increased competition from
other treatments.

Non GAAP cost of product sales as a percentage of product sales decreased
in Q2 2010 compared to the same period in 2009 as a result of changes in
sales mix towards higher margin products.

Research and development ("R&D")

                                                                    % of

Non GAAP R&D increased in absolute terms in 2010 compared to 2009 due to
continued investment across a number of R&D programs, principally VYVANSE
international, INTUNIV, LIALDA and other early stage development programs.

Non GAAP SG&A increased in part due to selling and marketing costs
incurred to support recently launched products and growth into new markets.

Gain on sale of product rights

For the three months to June 30, 2010 Shire recorded a gain of
$4.1m (2009: $nil) on the sale of product rights. This gain had been deferred
pending the transfer of the relevant consents following the disposal of the
products concerned to Laboratorios Almirall S.A. in 2007.

Reorganization costs

For the three months to June 30, 2010 Shire recorded
reorganization costs of $8.6 million (2009: $2.9 million) relating to the
transfer of manufacturing from its Owings Mills facility and the
establishment of a Swiss commercial hub.

Interest expense

For the three months to June 30, 2010 the Company incurred interest
expense of $8.3 million (2009: $10.1 million). Interest expense principally
relates to the coupon and deferred issue costs on Shire's $1,100 million
2.75% convertible bonds due 2014.

Taxation

The effective rate of tax for the three months to June 30, 2010 was 25%
(2009: -78%), and the effective tax rate on Non GAAP income was 25% (2009:
2%).

The Non GAAP effective tax rate in the second quarter of 2009 was
significantly reduced by the recognition of Massachusetts State tax credits
and losses, which reduced the effective tax rate on Non GAAP income by 23
percentage points in Q2 2009.

(1) For the three and six month periods ended June 30, 2010
and 2009, 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 three and six month periods ended June 30, 2009
the ordinary shares underlying the convertible bonds have not been included
in the calculation of the diluted weighted average number of shares, as the
effect of their inclusion would be anti-dilutive.

Notes to Editors

SHIRE PLC - registered in Jersey, No. 99854, 22 Grenville Street, St
Helier, Jersey JE4 8PX

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, the Company'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
the Company's Specialty Pharmaceutical and Human Genetic Therapies products,
as well as the ability to secure new products for commercialization and/or
development; government regulation of the Company's products; the Company's
ability to manufacture its products in sufficient quantities to meet demand;
the impact of competitive therapies on the Company's products; the Company's
ability to register, maintain and enforce patents and other intellectual
property rights relating to its products; the Company'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 the Company's

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 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 2010 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; and
    - Costs associated with the integration of companies.

    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; 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 2009 and 2010
Non GAAP earnings. A reconciliation of Non GAAP financial measures to the
most directly comparable measure under US GAAP is presented on pages 20 to
23.

Sales growth at CER, which is a Non GAAP measure, is computed by
restating 2010 results using average 2009 foreign exchange rates for the
relevant period.

Average exchange rates for the six months to June 30, 2010 were
$1.53:GBP1.00 and $1.33:EUR1.00 (2009: $1.49:GBP1.00 and $1.33:EUR1.00).
Average exchange rates for Q2 2010 were $1.49:GBP1.00 and $1.27:EUR1.00
(2009: $1.55:GBP1.00 and $1.36:EUR1.00).
