Elan Provides Shareholders with Categorical View on Value

Elan Corporation, plc (NYSE: ELN) (Elan) today is providing its shareholders and the market with an assessment of Tysabri’s value and Elan’s cash.

The information is being offered to enable proper and market driven assessment of Elan’s interest in the Tysabri asset and its cash as seen by Elan’s Board of Directors, executive management and financial advisors, Citi, Davy Corporate Finance, Morgan Stanley and Ondra Partners. The presentation slides accompanying this press release are available on our website at www.elan.com.

Mr. Robert A. Ingram, Chairman of Elan, provided the following commentary, "All of our actions have been, and will continue, to align our strategy in what we believe is in the best interest of our shareholders. We have had extensive analysis completed by our advisors and we believe the underlying value of Tysabri alone is between $11.85- $17.15. Adding our cash of $3.65 per share, these assets in aggregate are worth at least $ 15.50 and as much as $20.80. Royalty Pharma’s current bid of $12.50 substantially undervalues these assets and tendering shares at this level would be to the direct detriment to our shareholders. Any credible proposal which may be made by Royalty Pharma or any other party will, as previously stated, be considered by the Company.

Mr. Kelly Martin, Chief Executive Officer of Elan, added, "In addition to maximizing the value of Tysabri, we have provided our shareholders with four additional transactions for approval at the upcoming EGM that will enable Elan to diversify risk in terms of assets, molecules, therapeutic areas and geographies while – at the same time – having a positive and immediate impact on our P&L and capital structure. All of these transactions have been assessed from a shareholder point of view and are designed to balance the short, medium and long term investment proposition and to deliver sustainable growth and benefits.”

Assumptions and Sources and Bases

¹ Pre-deduction of operating expenses and based on "street" consensus estimates for worldwide Tysabri Revenues through 2016E from the following brokers: Bank of America Merrill Lynch, Barclays, Berenberg, Bernstein, Brean Capital, Canaccord Equity, Citigroup, Cowen & Company, Credit Suisse, Davy, Deutsche Bank, Goldman Sachs, Goldman Sachs, Jefferies, JMP Securities, JP Morgan, Lazard & Company, Leerink Swann, Morgan Stanley, Piper Jaffray, RBC Capital Markets, Stifel, UBS, Wells Fargo, and William Blair.

² Based on Berenberg Bank estimates for worldwide Tysabri sales from report issued by it on May 14, 2013.

³ Based on pro forma net cash of March 31^st, 2013 as set out in Elan's Q1 press release.

⁴ The Tysabri valuation is calculated pre-deduction of operating expenses. The value range does not include any of Elan's other current assets such as ELND005, Prothena, Proteotasis, JAI, or the new strategic transactions scheduled for approval at the EGM on June 17, 2013.

⁵ On 24 April 2013, Elan provided guidance to investors that it expected operating expenditure for FY13 to be between $170-190m, of which $150m was expected to be cash with the remainder non-cash. As outlined on 20 May 2013, included in this guidance was approximately $80m of cash expenses associated with ELND005. On the same date, and as a result of the divestment of ELND005, Elan guided that it expected its operating expenses to reduce by $35-45m for FY13 (representing approximately a half year impact of reduced operating costs). Due to the restrictions associated with being in an offer period under the Irish Takeover Rules, Elan is currently not in a position to update its guidance in relation to operating expenses. However, it intends to do so as soon as practicable. The level of operating expenses required to run the Elan business in the future could be expected to reflect the changed nature, and lighter infrastructure of that business as a pure play royalty recipient with no other operations. In this regard, as an example, a typical royalty recipient company, infrastructure light pharmaceutical business with all of its revenues derived from royalty streams, could be expected to have operating expenses of approximately $25m per year. For illustrative purposes, every $25m of operating expense would have a $0.55/share impact and $75m, a $1.70/share impact on the value of Tysabri royalty stream

⁶ Based on Royalty Pharma's offer price of $12.50 per share and Berenberg Bank estimates for worldwide Tysabri sales from report issued by it on May 14, 2013 and value of Elan cash (see note 3. above)
