NEWS RELEASE

Warner Chilcott Reports Operating Results for the Quarter Ended June 30, 2011

Lower Operating Expenses Continue to Drive Strong Adjusted Cash Net Income

DUBLIN, Ireland, August 5, 2011 – Warner Chilcott plc (NASDAQ: WCRX) today announced its results for the quarter ended June 30, 2011. As discussed more fully below, our results of operations in the quarter ended June 30, 2011 as compared to the prior year quarter were impacted by several important transactions in recent periods. In 2011, these transactions included the refinancing of our senior secured indebtedness, the restructuring of certain of our Western European operations, and the repurposing of our Manati, Puerto Rico manufacturing facility. In prior year periods, the significant transactions included our acquisition of Novartis Pharmaceuticals Corporation’s (“Novartis”) U.S. rights to ENABLEX in October 2010 (the “ENABLEX Acquisition”), our acquisition of the global branded prescription pharmaceuticals business (“PGP”) from The Procter & Gamble Company (“P&G”) in October 2009 (the “PGP Acquisition”), and our termination of our exclusive license to distribute LEO Pharma A/S’s (“LEO”) DOVONEX, TACLONEX and pipeline dermatology products in the U.S. and sale of certain related assets to LEO for $1,000 million in cash in September 2009 (the “LEO Transaction”).

Total revenue in the quarter ended June 30, 2011 was $670 million, a decrease of $146 million, or 18%, compared to the quarter ended June 30, 2010. The decrease in revenues as compared to the prior year quarter was primarily driven by declines in DOVONEX and TACLONEX net sales (as a result of the LEO Transaction described below), as well as a decrease in ACTONEL revenues due, in large part, to the loss of exclusivity in Western Europe.

We reported GAAP net income of $72 million, or $0.28 per diluted share, in the quarter ended June 30, 2011, compared with GAAP net income of $115 million, or $0.46 per diluted share, in the prior year quarter. Cash net income (or CNI, as defined below) for the quarter ended June 30, 2011 was $221 million compared to $269 million in the prior year quarter. Adjusted CNI was $240 million in the quarter ended June 30, 2011, a decrease of $1 million, or 1%, compared to our adjusted CNI of $241 million in the prior year quarter. In computing adjusted CNI for the quarter ended June 30, 2011, we excluded $15 million of restructuring costs, net of tax, related to the restructuring of certain of our Western European operations and $3 million of charges, net of tax, in cost of sales relating to the repurposing of our Manati manufacturing facility. In computing adjusted CNI for the quarter ended June 30, 2010, we excluded $18 million of income, net of tax, from the reversal of a contingent liability and a $9 million gain, net of tax, recognized on the sale of certain inventories to LEO in connection with the LEO Transaction.

References in this press release to “cash net income” or “CNI” mean our net income adjusted for the after-tax effects of two non-cash items: amortization (including impairments, if any) of intangible assets and amortization (including write-offs, if any) of deferred loan costs related to our debt. Adjusted CNI represents CNI as further adjusted to exclude certain after-tax impacts from the Western European restructuring, the repurposing of the Manati facility, the LEO Transaction, the PGP Acquisition and the reversal of a contingent liability relating to the termination of a contract. Reconciliations from our reported results in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”) to CNI, adjusted CNI and adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) for all periods presented are included in the tables at the end of this press release.

Strategic Initiatives

Western European Restructuring and Repurposing of the Manati Facility

In April 2011, we announced a plan to restructure our operations to move to a wholesale distribution model and minimize our operational costs in Belgium, the Netherlands, France, Germany, Italy, Spain, Switzerland and the United Kingdom. The implementation of the restructuring plan, which is expected to impact approximately 500 employees, and the aggregate amounts to be expensed, remain subject to consultation with local works councils in certain European jurisdictions. Severance costs of $15 million were recorded in the quarter ended June 30, 2011 and were included as a component of restructuring costs in our condensed consolidated statement of operations. Also included as restructuring costs in our condensed consolidated statement of operations were contract termination expenses of $1 million in the quarter ended June 30, 2011.

In April 2011, we announced a plan to repurpose our Manati, Puerto Rico manufacturing facility. Going forward this facility will serve as a warehouse and distribution center. As a result of the repurposing, we recorded severance costs of $1 million and a charge of $2 million for the write-down of certain property, plant and equipment in the quarter ended June 30, 2011. These expenses were included as a component of cost of sales.

We currently estimate that we will incur aggregate pretax costs as a result of the Western European restructuring and the Manati repurposing in the range of $160 million to $170 million based on current exchange rates, with the majority of such charges expected

to be recorded in fiscal year 2011. Of this amount, we recorded $19 million ($18 million, net of tax) and $90 million ($87 million, net of tax) in the quarter and six months ended June 30, 2011, respectively. In computing adjusted CNI for the quarter and six months ended June 30, 2011, we added back to CNI the after tax impact of the restructuring and repurposing costs. We intend to add back the aggregate restructuring and repurposing charges (net of tax) in computing adjusted CNI in future periods.

Revenue

Total revenue in the quarter ended June 30, 2011 was $670 million, a decrease of $146 million, or 18%, compared to the quarter ended June 30, 2010. For the quarter ended June 30, 2011, the decrease in revenues as compared to the prior year quarter was driven primarily by a decrease in DOVONEX and TACLONEX net sales of $76 million (as a result of the LEO Transaction) and a decrease in ACTONEL revenues of $71 million due, in large part, to the loss of exclusivity in Western Europe. Period over period changes in the net sales of our products are a function of a number of factors including changes in: market demand, gross selling prices, sales-related deductions from gross sales to arrive at net sales and the levels of pipeline inventories of our products held by our direct and indirect customers. In addition, transactions such as the LEO Transaction and the ENABLEX Acquisition also impact our period over period net sales. We use IMS Health, Inc. (“IMS”) estimates of filled prescriptions for our products as a proxy for market demand in the U.S.

Global revenues of ACTONEL were $193 million in the quarter ended June 30, 2011 compared to $264 million in the prior year quarter. The 27% decrease in ACTONEL global revenues in the quarter ended June 30, 2011 relative to the prior year quarter was attributable in large part to the loss of exclusivity in Western Europe which began in the fourth quarter of 2010. ACTONEL revenues outside of North America were $65 million in the quarter ended June 30, 2011, down 35% from $101 million in the prior year quarter. Revenues of ACTONEL in North America for the quarters ended June 30, 2011 and 2010 were $128 million and $163 million, respectively, including $106 million and $144 million, respectively, in the United States. In the United States, ACTONEL revenues decreased $38 million compared to the prior year quarter primarily due to a decrease in filled prescriptions of 31%, offset, in part by higher average selling prices, as compared to the prior year quarter. In the U.S., ACTONEL continues to face market share declines due to the impact of managed care initiatives that encourage the use of generic versions of other products, such as Fosamax, as well as declines in filled prescriptions within the overall oral bisphosphonate market. While we expect to continue to experience significant declines in global ACTONEL revenues throughout the remainder of 2011 relative to 2010, we expect revenues from our new product ATELVIA will grow and partially offset some of those declines in the U.S. market. ATELVIA, which we began to promote in the U.S. in early 2011, generated net sales of $8 million in the quarter ended June 30, 2011.

Net sales of our oral contraceptive products increased $6 million, or 6%, in the quarter ended June 30, 2011, compared with the prior year quarter. LOESTRIN 24 FE generated revenues of $102 million in the quarter ended June 30, 2011, an increase of 15%, compared with $89 million in the prior year quarter. The increase in LOESTRIN 24 FE net sales was primarily due to a decrease in sales-related deductions and higher average selling prices, offset in part by a contraction of pipeline inventories relative to the prior year quarter as well as a decrease in filled prescriptions of 1%. LO LOESTRIN FE, which we began to promote in the U.S. in early 2011, generated net sales of $11 million in the quarter ended June 30, 2011. In March 2011, as expected, Teva Pharmaceuticals Industries, Ltd. launched a generic version of our FEMCON FE product. FEMCON FE revenues in the quarter ended June 30, 2011, which we report in “Other Oral Contraceptives” revenue, were negatively impacted by the new generic competition. We anticipate net sales of FEMCON FE will continue to decline during 2011 as compared to the prior year periods as a result of generic competition.

Net sales of ESTRACE Cream increased $4 million, or 13%, in the quarter ended June 30, 2011, as compared to the prior year quarter. The increase was primarily due to higher average selling prices and a 9% increase in filled prescriptions in the quarter ended June 30, 2011, as compared to the prior year quarter.

Net sales of ASACOL were $188 million in the quarter ended June 30, 2011, a decrease of 2%, compared with $192 million in the prior year quarter. ASACOL revenues in North America in the quarters ended June 30, 2011 and 2010 totaled $175 million and $179 million, respectively, including revenues in the U.S. of $168 million and $174 million, respectively. The decrease in ASACOL net sales in the U.S. was primarily due to an increase in sales-related deductions offset, in part, by higher average selling prices as compared to the prior year quarter.

Net sales of our dermatology products decreased $95 million, or 75%, in the quarter ended June 30, 2011, as compared to the prior year quarter. This decrease relative to the prior year quarter was primarily due to a $76 million decrease in net sales of DOVONEX and TACLONEX resulting from LEO’s assumption of responsibility for the distribution of DOVONEX and TACLONEX on June 30, 2010. From the closing of the LEO Transaction in September 2009 until June 30, 2010, we recorded net sales (and cost of sales) for all DOVONEX and TACLONEX products sold in the U.S. at nominal distributor margins pursuant to the distribution agreement executed in connection with the LEO Transaction. We did not record any net sales of DOVONEX or TACLONEX in the quarter ended June 30, 2011. Net sales of DORYX decreased $19 million, or 37%, in the quarter ended June 30, 2011, compared to the prior year quarter, primarily due to a decrease in filled prescriptions of 46% and a contraction of pipeline inventories relative to the prior year quarter, offset, in part by a decrease in sales-related deductions and higher average selling prices. The decrease in sales-related deductions compared with the prior year quarter was primarily a result of changes to our loyalty card program in early 2011 which reduced the rebate offered to patients on DORYX 150 mg. As expected, the reduction in the rebate resulted in decreased usage of our customer loyalty card for DORYX 150 mg and a meaningful decline in filled prescriptions of DORYX 150 mg relative to the prior year quarter. Offsetting the decline in filled prescriptions were significantly higher average net sales values per prescription for DORYX 150 mg.

Revenues of ENABLEX in the quarter ended June 30, 2011 were $40 million, an increase of 90%, compared to $21 million in the prior year quarter. The increase in ENABLEX revenues in the quarter ended June 30, 2011 relative to the prior year quarter was primarily attributable to the ENABLEX Acquisition in October 2010 pursuant to which we acquired the U.S. rights to ENABLEX. As a result of the ENABLEX Acquisition, we began to record sales of ENABLEX in product net sales on a gross basis as we became the principal in the sales transactions. During periods prior to the ENABLEX Acquisition, including the quarter ended June 30, 2010, we recorded ENABLEX revenue based on the contractual percentage we received of Novartis’ net sales pursuant to our co-promotion agreement with Novartis. Filled prescriptions of ENABLEX in the U.S. decreased 8% in the quarter ended June 30, 2011 compared to the prior year quarter.

Cost of Sales (Excluding Amortization of Intangible Assets)

Cost of sales (excluding amortization) decreased $33 million, or 30%, in the quarter ended June 30, 2011 compared with the prior year quarter. The quarter ended June 30, 2011 included $3 million of costs related to the repurposing of our Manati facility. The quarter ended June 30, 2010 included approximately $76 million of costs related to DOVONEX and TACLONEX products distributed at nominal distributor margins under the LEO distribution agreement. These costs in the quarter ended June 30, 2010 were offset, in part, by a $10 million gain relating to the sale of certain inventories in connection with the LEO Transaction. Also included in cost of sales in the prior year quarter was an $18 million reduction in cost of sales as a result of the reversal of a contingent liability relating to the termination of a contract. Excluding the impact in the applicable quarter of the items mentioned above, our gross profit margin as a percentage of total revenue, excluding the impact of the revenues under the LEO distribution agreement ($76 million) in the prior year quarter, decreased in the quarter ended June 30, 2011 relative to the prior year quarter from 92% to 89% primarily due to the mix of products sold and the fact that there were no costs of sales associated with our ENABLEX revenue in the prior year quarter.

Selling, General and Administrative (“SG&A”) Expenses

SG&A expenses for the quarter ended June 30, 2011 were $246 million, a decrease of $35 million, or 12%, from $281 million in the prior year quarter. Advertising and promotion (“A&P”) expenses for the quarter ended June 30, 2011 increased $10 million, or 36%, compared to the prior year quarter, primarily due to advertising and other promotional expenses attributable to the U.S. launches of ATELVIA and LO LOESTRIN FE. Selling and distribution expenses for the quarter ended June 30, 2011 decreased $3 million, or 2%, compared to the prior year quarter. The decrease was primarily due to a decrease in the Sanofi co-promotion expense of $5 million as a result of decreased ACTONEL revenues in Western Europe, offset, in part, by increases in promotional spending related to the U.S. launches of ATELVIA and LO LOESTRIN FE. General, administrative and other (“G&A”) expenses in the quarter ended June 30, 2011 decreased $42 million, or 35%, as compared to the prior year quarter primarily due to the following charges which were included in G&A expenses in the quarter ended June 30, 2010: (i) $8 million of legal, consulting and other professional fees relating primarily to the PGP Acquisition, (ii) $16 million of expenses payable to P&G under the transition services agreement entered into in connection with the PGP Acquisition, (iii) $12 million of other integration expenses and (iv) $2 million of severance costs.

Research and Development (“R&D”)

Our investment in R&D for the quarter ended June 30, 2011 was $25 million, a decrease of $26 million, or 50%, as compared to the prior year quarter. The decrease was primarily due to the $20 million up-front payment to Dong-A PharmTech Co. Ltd. (“Dong-A”), resulting from the amendment of our agreement to add the right to develop, and if approved, market, in the U.S. and Canada, Dong-A’s udenafil product for the treatment of lower urinary tract symptoms associated with Benign Prostatic Hyperplasia, which was included in R&D expenses in the quarter ended June 30, 2010. Our R&D expenses consist of our internal development costs, fees paid to contracted development groups and license fees paid to third parties. R&D expenditures are subject to fluctuation due to the stage and timing of our R&D projects.

Amortization of Intangible Assets

Amortization of intangible assets in the quarters ended June 30, 2011 and 2010 was $148 million and $157 million, respectively. We expect our 2011 amortization expense to decline compared to 2010 as most of our intangible assets are amortized on an accelerated basis under the economic benefit model. This decline in 2011 is expected to be offset, in part, by amortization expense associated with certain of our new products, such as ATELVIA, and as a result of the ENABLEX Acquisition.

Net Interest Expense

Net interest expense for the quarter ended June 30, 2011 was $65 million, an increase of $22 million, or 51%, from $43 million in the prior year quarter. The increase was primarily due to an increase in our average outstanding indebtedness relative to the prior year quarter due primarily to the timing of the incurrence of indebtedness during 2010 in connection with our payment of the special cash dividend of $8.50 per share, or $2,144 million in the aggregate, to shareholders of record on August 30, 2010 and the ENABLEX Acquisition. This increase in our average outstanding indebtedness relative to the prior year quarter was offset, in part, by lower interest rates under our senior secured credit facilities in the quarter ended June 30, 2011 compared to the prior year quarter.

Net Income, Cash Net Income and Adjusted Cash Net Income

For the quarter ended June 30, 2011, we reported net income of $72 million, or $0.28 per diluted share, CNI of $221 million, and adjusted CNI of $240 million, or $0.94 per diluted share. Earnings per share for the quarter is based on 255 million diluted ordinary shares outstanding. In calculating CNI, we add back the after-tax impact of the amortization (including impairments, if any) of intangible assets and the amortization (including write-offs, if any) of deferred loan costs. These items are tax-effected at the estimated marginal rates attributable to them. In the quarter ended June 30, 2011, the marginal tax rate associated with the amortization of intangible assets was 5.1% and the marginal tax rate for amortization (including write-offs) of deferred loan costs was 6.1%. Adjusted CNI for the quarter ended June 30, 2011 represents CNI as further adjusted to exclude $15 million, net of tax, of costs related to the restructuring of certain of our Western European operations and $3 million, net of tax, of charges relating to the repurposing of our Manati manufacturing facility.

Liquidity, Balance Sheet and Cash Flows

As of June 30, 2011, our cash on hand was $262 million and our total outstanding debt was $4,073 million, which consisted of $2,814 million of borrowings under our senior secured credit facilities (the “New Senior Secured Credit Facilities”), $1,250 million aggregate principal amount of 7.75% senior notes due 2018 (the “7.75% Notes”), and $9 million of unamortized premium related to the 7.75% Notes. We generated $260 million of cash from operating activities in the quarter ended June 30, 2011, compared with $120 million of cash from operating activities in the prior year quarter, an increase of $140 million.

2011 Financial Guidance Update

Based on our second quarter results and current outlook for the remainder of 2011, we are reaffirming our adjusted CNI per share for the full year 2011 of a range of $3.70 to $3.80. We continue to expect our 2011 revenue to be in the range of $2,700 to $2,800 million based on current revenue trends, but we no longer expect revenue to be at the high end of our range as previously disclosed. In addition, we are reducing our expected R&D expenses as a result of changes in the expected timing of expenses with respect to projects under development from a range of $130 to $150 million to a range of $120 to $140 million.

For the complete list of changes to the Company’s full year 2011 guidance, please refer to the table on the last page of this press release.

These statements constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. The words “may,” “might,” “will,” “should,” “estimate,” “project,” “plan,” “anticipate,” “expect,” “intend,” “outlook,” “believe” and other similar expressions are intended to identify forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of their dates. These forward-looking statements are based on estimates and assumptions by our management that, although we believe to be reasonable, are inherently uncertain and subject to a number of risks and uncertainties. The following represent some, but not necessarily all, of the factors that could cause actual results to differ from historical results or those anticipated or predicted by our forward-looking statements: our substantial indebtedness, including increases in the LIBOR rates on our variable-rate indebtedness above the applicable floor amounts; competitive factors in the industry in which we operate, including the approval and introduction of generic or branded products that compete with our products; our ability to protect our intellectual property; a delay in qualifying any of our manufacturing facilities that produce our products or production or regulatory problems with either our own manufacturing facilities or third party manufacturers or API suppliers upon whom we may rely for some of our products; pricing pressures from reimbursement policies of private managed care organizations and other third party payors, government sponsored health systems, and the continued consolidation of the distribution network through which we sell our products; changes in tax laws or interpretations that could increase our consolidated

tax liabilities; government regulation, including U.S. and foreign health care reform, affecting the development, manufacture, marketing and sale of pharmaceutical products, including our ability and the ability of companies with whom we do business to obtain necessary regulatory approvals; adverse outcomes in our outstanding litigation or arbitration matters or an increase in the number of litigation matters to which we are subject; the loss of key senior management or scientific staff; our ability to manage the growth of our business by successfully identifying, developing, acquiring or licensing new products at favorable prices and marketing such new products; our ability to obtain regulatory approval and customer acceptance of new products, and continued customer acceptance of our existing products; our ability to realize the anticipated opportunities from the PGP Acquisition; and the other risks identified in our periodic filings including our Annual Report on Form 10-K for the year ended December 31, 2010, and from time-to-time in our other investor communications.

Reconciliations to GAAP Net Income

CNI and Adjusted CNI

To supplement our condensed consolidated financial statements presented in accordance with US GAAP, we provide a summary to show the computation of CNI and adjusted CNI. CNI is defined as our GAAP net income adjusted for the after-tax effects of two non-cash items: amortization (including impairments, if any) of intangible assets and amortization (including write-offs, if any) of deferred loan costs related to our debt. Adjusted CNI represents CNI as further adjusted to exclude certain after-tax impacts from the Western European restructuring, the repurposing of the Manati facility, the LEO Transaction, the PGP Acquisition and the reversal of a contingent liability relating to the termination of a contract. We did not recognize a tax benefit as a result of the repurposing of the Manati facility. We believe that the presentation of CNI and adjusted CNI provides useful information to both management and investors concerning the approximate impact of the above items. We also believe that considering the effect of these items allows management and investors to better compare our financial performance from period-to-period, and to better compare our financial performance with that of our competitors. The presentation of this additional information is not meant to be considered in isolation of, or as a substitute for, results prepared in accordance with US GAAP.

Adjusted EBITDA

To supplement our condensed consolidated financial statements presented in accordance with US GAAP, we provide a summary to show the computation of Adjusted EBITDA taking into account certain charges that were taken during the quarters and six months ended June 30, 2011 and 2010. The computation of Adjusted EBITDA is based on the definition of Adjusted EBITDA contained in our New Senior Secured Credit Facilities.
