PfizerPfizer Inc. (NYSE: PFE) and Hospira, Inc. (NYSE: HSP) have entered into a definitive merger agreement under which Pfizer will acquire Hospira, the world's leading provider of injectable drugs and infusion technologies and a global leader in biosimilars, for $90 a share in cash for a total enterprise value of approximately $17 billion. The Boards of Directors of both companies have unanimously approved the merger, which is expected to be immediately accretive upon closing, accretive by $0.10 - $0.12 per share for the first full year following the close of the transaction with additional accretion anticipated thereafter.

"The proposed acquisition of Hospira demonstrates our commitment to prudently deploy capital to create shareholder value and deliver incremental revenue and EPS growth in the near-term," said Ian Read, Chairman and Chief Executive Officer, Pfizer. "In addition, Hospira's business aligns well with our new commercial structure and is an excellent strategic fit for our Global Established Pharmaceutical business, which will benefit from a significantly enhanced product portfolio in growing markets. Coupled with Pfizer's global reach, Hospira is expected to drive greater sustainability for our Global Established Pharmaceutical business over the long term."

This strategically complementary combination will add a growing revenue stream and a platform for growth for Pfizer's GEP business. The expanded portfolio of sterile injectable pharmaceuticals, composed of Hospira's broad generic sterile injectables product line, including acute care and oncology injectables, with a number of differentiated presentations, as well as its biosimilars portfolio, combined with GEP’s branded sterile injectables, including anti-infectives, anti-inflammatories and cytotoxics, will create a leading global sterile injectables business. The combination also reinforces GEP's growth strategy to build a broad portfolio of biosimilars in Pfizer's therapeutic areas of strength through the addition of Hospira's portfolio that includes several marketed biosimilars. Pfizer will also use its existing commercial capabilities, global scale, scientific expertise and world class development capabilities to significantly expand the reach of Hospira's products, which are currently distributed primarily in the United States, to Europe and key emerging markets, where GEP has a significant presence.

"The addition of Hospira has the potential to fundamentally improve the growth trajectory of the Global Established Pharmaceutical business, vault it into a leadership position in the large and growing off-patent sterile injectables marketplace by combining the specialized talent and capabilities of both companies, including enhanced manufacturing, and advance its goal to be among the world's most preeminent biosimilars providers," said John Young, group president, Pfizer Global Established Pharmaceutical business. "We're excited to combine Hospira's expertise and key talent with that of Pfizer to create a leading global business that will deliver an even broader portfolio of important and life-saving sterile injectable medicines to patients around the world."

"The Pfizer-Hospira combination is an excellent strategic fit, presenting a unique opportunity to leverage the complementary strengths of our robust portfolios and rich pipelines," said F. Michael Ball, Chief Executive Officer, Hospira. "I want to recognize and thank our 19,000 employees around the world for their tireless efforts to deliver more affordable healthcare solutions, increase patient access to high-quality care and drive sustained growth for our shareholders."

Both sterile injectables and biosimilars are large and growing categories. The global marketplace value for generic sterile injectables is estimated to be $70 billion in 2020. The global marketplace for biosimilars is estimated to be approximately $20 billion in 2020.

Pfizer expects to finance the transaction through a combination of existing cash and new debt, with approximately two-thirds of the value financed from cash and one-third from debt. In addition, Pfizer anticipates the transaction to deliver $800 million in annual cost savings by 2018.

The transaction is subject to customary closing conditions, including regulatory approvals in several jurisdictions and approval of Hospira's shareholders, and is expected to close in the second half of 2015.

Pfizer's financial advisors for the transaction were Guggenheim Securities, J.P. Morgan and Lazard, with Ropes & Gray LLP acting as its legal advisor and Clifford Chance LLP advising on international regulatory matters. Morgan Stanley served as Hospira's financial advisor, while Skadden, Arps, Slate, Meagher & Flom LLP & Affiliates served as its legal advisor.
