Astellas Pharma Inc. (OSIP) Offers to Acquire OSI Pharmaceuticals for $52.00 Per Share in Cash

TOKYO, March 1 /PRNewswire-FirstCall/ — Astellas Pharma Inc. (TSE: 4503), a global pharmaceutical company, will commence a tender offer to acquire all outstanding shares of common stock of OSI Pharmaceuticals (Nasdaq: OSIP) for $52.00 per share in cash, or an aggregate of approximately $3.5 billion on a fully diluted basis.

The all-cash offer, set forth in Astellas’ letter to OSI delivered this morning, represents a significant premium of over 40% on the closing price of OSI’s common stock of $37.02 per share on February 26, 2010, a 53% premium to its three-month average of $34.01 per share, and a 31% premium to its 52-week high of $39.66 per share. Astellas’ offer is not subject to any financing conditions.

The acquisition of OSI – a biotechnology company primarily focused on the discovery, development and commercialization of molecular targeted therapies addressing medical needs in oncology, diabetes and obesity – would support Astellas’ growth strategy of becoming a Global Category Leader in oncology. OSI manufactures and sells Tarceva (erlotinib), a leading cancer medication and has several prospective new oncology medications in its R&D pipeline. The transaction would provide Astellas with a top-tier oncology business in the U.S. and an expanded product portfolio and pipeline. OSI would also augment Astellas’ strong existing franchises in urology and immunology.

Astellas’ scale and financial strength will help OSI realize the value of its current product pipeline, as well as continue the necessary funding of its discovery engine. Adding Astellas’ strong business operations and experience in the development and sales of new products will enable the combined company to accelerate their development and ensure their successful commercialization. Astellas has great respect for the OSI organization and expects to integrate the strengths of OSI’s business and employees into its operations as it has in the past with similar strategic acquisitions.

Masafumi Nogimori, President and Chief Executive Officer of Astellas, commenting on the offer, said, “This offer follows our attempts over the past 13 months to engage OSI in meaningful discussions. We firmly believe in the compelling strategic rationale behind the combination and the opportunity it provides to the OSI stockholders to realize full and fair value, in cash, immediately. As recently as February 12, 2010, Astellas presented this proposal to acquire OSI, which reflected a 50% premium on that date. However, we received a response stating that our offer ‘very significantly undervalues’ OSI. That response was the latest indication to us that OSI is not interested in engaging in substantive discussions. We are therefore taking our offer directly to OSI’s stockholders. Our proposal and its significant premium recognize both the value created by OSI to date and its future prospects. Of course, we are open to, and we hope that OSI’s Board and management will commence, discussions with us to effect a negotiated transaction.”

Astellas has made numerous attempts to engage in substantive discussions to acquire OSI. Astellas first raised its interest in acquiring OSI during a meeting with OSI’s CEO in January 2009 and made its first written proposal in February 2009. Despite subsequent letters reiterating Astellas’ interest in March and June 2009 and several face-to-face meetings, including a meeting between the two CEOs on February 12, 2010, OSI has refused to engage in a meaningful discussion. As a result, Astellas has decided to commence a tender offer and go directly to the OSI stockholders. Astellas will consider all means necessary to secure a completed transaction. Among other things, Astellas intends to nominate directors at OSI’s upcoming annual meeting to give stockholders a voice in the outcome.

Astellas will commence a tender offer on March 2, 2010, to purchase all outstanding common stock of OSI for $52.00 per share in cash. Following successful completion of the tender offer, a merger will be completed at the same price. The complete terms and conditions of the offer will be filed with the U.S. Securities and Exchange Commission and disseminated to OSI stockholders. Astellas has cash and cash equivalents on hand to complete the transaction. The offer is not subject to any financing or due diligence conditions, and will be subject only to customary closing conditions, including the tender of a majority of OSI’s shares of common stock on a fully diluted basis, and OSI’s Board taking all necessary actions to make its stockholder rights plan and Section 203 of the Delaware Corporation Law inapplicable to Astellas’ offer. There are no anticipated regulatory hurdles to completion.

Citigroup is acting as exclusive financial advisor to Astellas and Morrison & Foerster LLP is acting as legal counsel.

Following is a copy of the letter Astellas sent earlier today to Colin Goddard, OSI’s CEO:

    March 1, 2010
    Colin Goddard, Chief Executive Officer, OSI Pharmaceuticals
    Cc: Robert A. Ingram, Chairman, OSI Pharmaceuticals

Dear Dr. Goddard:

As you know from our meetings, we have a great deal of respect for you and OSI, its employees and what the company has achieved. We believe there are significant benefits from OSI’s acquisition by Astellas and believe that a combined entity would allow us to achieve the goal of discovering, developing and delivering novel medications for patients with unmet needs in the oncology space far better than each of our companies could do independently.

When we met on February 12, 2010, I presented our proposal to acquire all of OSI shares for $52 per share, a 50% premium to the prior day’s closing price. This followed Astellas’ numerous attempts to engage in meaningful conversations with OSI over the last 13 months regarding the potential for bringing our two businesses together.

I was hopeful that our February 12th meeting would have finally resulted in a constructive attempt by you and OSI’s Board to discuss a transaction and bring value to your stockholders. Instead, your written response dated February 22nd stated that our proposal “very significantly undervalues” OSI. It also contained a confidentiality agreement with a two-year “standstill” provision which we believe would not be in your stockholders’ best interests, as it would have restricted us from making our offer directly to them.

As we have stated to you consistently in our many communications to you over the last 13 months, we believe the acquisition of OSI by Astellas makes for a compelling business proposition and provides a unique opportunity for our respective stockholders, employees and customers. However, because your response indicates that you have no intention to engage in substantive discussions, our Board has authorized me to take our offer directly to OSI’s stockholders.

We remain enthusiastic about the potential of this transaction to realize the value of OSI’s current commercialized products and to ensure the successful development and commercialization of additional products from its pipeline. We respect your organization very much, and as such we would expect to integrate the strengths of your business and of OSI’s employees into our company as we have in the past with similar strategic acquisitions.

Our proposal would be subject to standard acquisition conditions, including the removal of your stockholder rights plan, and is not subject to any financing or any due diligence conditions. We do not foresee any regulatory or other impediment to closing.

We continue to be excited about the possibility of bringing our two organizations together and we hope that you and your Board will reconsider your position and work with us to achieve a mutually beneficial outcome. Astellas has engaged Citigroup as financial advisor and Morrison & Foerster LLP as legal counsel to assist us in completing this transaction. We and our advisors stand ready to meet with you and your advisors to answer any questions you may have about our offer.

    Very truly yours,

    Masafumi Nogimori
    Chief Executive Officer

    cc:  Toichi Takenaka, Chairman
