Bristol-Myers Squibb to Acquire ZymoGenetics

Bristol-Myers Squibb CompanyBristol-Myers Squibb Company (NYSE:BMY) and ZymoGenetics, Inc. (NASDAQ: ZGEN) announced today that the companies have signed a definitive agreement providing for the acquisition of ZymoGenetics by Bristol-Myers Squibb, for $9.75 per share in cash. The transaction, with an aggregate purchase price of approximately $885 million, or approximately $735 million net of cash acquired, has been unanimously approved by the boards of directors of both companies. The board of directors of ZymoGenetics intends to recommend that ZymoGenetics' shareholders tender their shares in the tender offer. In addition, shareholders holding approximately 37% of the outstanding shares of ZymoGenetics' common stock have entered into agreements with Bristol-Myers Squibb to support the transaction and to tender their shares in the offer.

"The acquisition of ZymoGenetics brings us full ownership of a promising investigational biologic that strengthens our very diversified Hepatitis C portfolio. Building on our leadership in virology, we are developing a strong portfolio to help patients with Hepatitis C," said Lamberto Andreotti, chief executive officer, Bristol-Myers Squibb. "In addition, ZymoGenetics brings proven capabilities with therapeutic proteins and revenue from a marketed specialty surgical biologic. This acquisition is another example of our strategic, targeted approach to business development."

"By joining forces with Bristol-Myers Squibb, we believe we will enhance the long-term potential of ZymoGenetics' portfolio of assets, while providing a compelling valuation for our shareholders," said Douglas E. Williams, Ph.D., chief executive officer of ZymoGenetics. "Our collaboration with Bristol-Myers Squibb in the development of PEG-Interferon lambda has been extremely positive and it has given us an opportunity to fully appreciate their capabilities. We believe that this transaction will maximize the potential for our products and product candidates to make a meaningful difference for patients in need."

Bristol-Myers Squibb gains the following as a result of the acquisition:

  • Full ownership of pegylated-interferon lambda, a novel interferon in Phase IIb development for the treatment of Hepatitis C infection, which, if approved, could be an important contributor to Bristol-Myers Squibb's future growth. The companies have collaborated on the development of pegylated-interferon lambda since January 2009. Four-week and 12-week results from a Phase IIa study will be presented at the American Association for the Study of Liver Diseases meeting later this year.
  • RECOTHROM®, a recombinant thrombin approved by the U.S. Food and Drug Administration for use as a topical hemostat to control non-arterial bleeding during surgical procedures.
  • IL-21 protein, a cytokine currently being tested in an open-label, Phase II clinical study as a potential immunotherapy treatment for metastatic melanoma.
  • An earlier-stage pipeline of six biologic drug candidates, including an anti-IL-31 antibody, currently in pre-clinical development for atopic dermatitis.
  • Potential milestone and royalty payments from six partnered programs in various stages of clinical development by EMD Serono, Inc., an affiliate of Merck KGaA, and Novo Nordisk.

"ZymoGenetics is a leader in advancing novel biologics, particularly genomics-based therapies," said Elliott Sigal, M.D., Ph.D., executive vice president and chief scientific officer, Bristol-Myers Squibb. "We expect ZymoGenetics’ pipeline and biologics capabilities to complement and enhance our existing efforts in Hepatitis C, oncology and immunoscience."

Initially, the transaction is expected to be modestly dilutive to earnings per share (EPS) for Bristol-Myers Squibb. In 2010, the transaction is expected to be dilutive to EPS by approximately $0.03. In 2011, the transaction is expected to be dilutive to EPS by approximately $0.07.

Under the terms of the definitive agreement, Bristol-Myers Squibb will commence a cash tender offer on or about September 9, 2010, to purchase all of the outstanding shares of ZymoGenetics' common stock for $9.75 per share. The closing of the tender offer is subject to customary terms and conditions, including the tender of a number of shares which is equal to or greater than 48,282,192 shares (which represents approximately 56% of the outstanding shares as of August 31, 2010, which represents a majority of the shares on a fully-diluted basis, excluding certain shares underlying derivative securities that are significantly out-of-the-money), and the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. The agreement also provides for the parties to effect, subject to customary conditions, a merger to be completed following the completion of the tender offer which would result in all shares not tendered in the tender offer being converted into the right to receive $9.75 per share in cash. The merger agreement contains a provision under which ZymoGenetics has agreed not to solicit any competing offers for the company. Bristol-Myers Squibb will finance the acquisition from its existing cash resources. The companies expect the tender offer to close approximately thirty days after commencement of the tender offer.

Morgan Stanley & Co. Incorporated is serving as financial advisor to Bristol-Myers Squibb in connection with the acquisition, and Bristol-Myers Squibb is represented by Kirkland & Ellis LLP. Goldman, Sachs & Co. is serving as financial advisor to ZymoGenetics in connection with the acquisition, and ZymoGenetics is represented by Latham & Watkins LLP and Fenwick & West LLP.
