Zoetis Inc. operates as the world’s largest animal health company, developing and commercializing medicines, vaccines, and diagnostic products for livestock and companion animals. The company manages operations across four geographic segments: United States, Europe/Africa/Middle East, Canada/Latin America, and Asia/Pacific.
The business focuses on core species including cattle, swine, poultry, fish, sheep, dogs, cats, and horses. Product categories span vaccines, parasiticides, anti-infectives, diagnostics, and medicated feed additives. Zoetis markets products directly in approximately 45 countries and distributes in more than 100 countries worldwide.
Originally established as Pfizer’s Agriculture Division in 1952, the company operated as Pfizer Animal Health for decades before spinning off as an independent entity. The transition to Zoetis marked a strategic shift for both organizations, enabling focused growth in the animal health sector.
Zoetis History
Pfizer established the Agriculture Division at a 732-acre research facility in Terre Haute, Indiana, called Vigo. Chemical engineer John McKeen discovered the effective use of oxytetracycline in livestock, marking the company’s entry into animal health.
The division officially became Pfizer Animal Health, reflecting its growth and importance within the pharmaceutical giant’s portfolio.
Pfizer acquired Norden Laboratories from GlaxoSmithKline, expanding capabilities in small animal care including domestic pets. This acquisition significantly broadened the product portfolio beyond livestock.
Secondary research and development centers opened in Kalamazoo, Michigan. The same year, Pfizer acquired Pharmacia Corporation for $60 billion, bringing additional animal health assets into the division.
Aggressive acquisition period brought in Embrex Inc., Catapult Genetics, Bovigen, Wyeth, Fort Dodge Animal Health, Synbiotics Corporation, King Pharmaceuticals, and Alpharma. These transactions greatly expanded market presence, product range, and operational resources.
Pfizer announced plans to spin off the Animal Health division as an independent company. The name Zoetis was chosen, derived from the Latin word “zoetic” meaning pertaining to life. Revenue reached $4.34 billion.
Zoetis completed its IPO on February 1, selling 86.1 million shares for $2.2 billion. Shares rose 19% by day’s end, reaching $35.01 from the $26 opening price. At the time, this represented the largest U.S. company IPO since Facebook. Pfizer retained an 83% stake initially.
Acquired animal health assets from Abbott Laboratories, expanding the companion animal portfolio with products for anesthesia, pain management, and diabetes treatment.
Purchased Nexvet to strengthen monoclonal antibody therapies for companion animals, supporting development of innovative treatment options.
Completed the $2 billion acquisition of Abaxis, a leading provider of veterinary point-of-care diagnostic instruments. This added the VetScan portfolio of benchtop and handheld diagnostic tools.
Acquired Platinum Performance, a leading nutrition-focused animal health business. Kristin Peck was named to succeed Juan Ramón Alaix as CEO.
Completed acquisition of Jurox, a privately held animal health company based in Australia, bringing important products including Alfaxan anesthetic for companion animals.
Acquired Petmedix, a Cambridge, UK-based company specializing in species-specific antibody therapies for pets.
Revenue reached $9.3 billion, representing 8% growth. The company divested its medicated feed additive portfolio to focus on core growth areas. Operations expanded to serve customers in over 100 countries.
Zoetis Leadership
First CEO of Zoetis from 2012 to 2019, Alaix led the company through its formation and separation from Pfizer. Under his leadership, revenue grew from $4.3 billion to $5.8 billion, and market capitalization reached $60 billion.
Current CEO since January 2020, Peck joined the executive team at Zoetis formation in 2012. She previously led U.S. Operations, Business Development, and Strategy, driving consistent revenue growth and successful product launches including Simparica and Cytopoint.
Zoetis Revenue
Zoetis has demonstrated consistent revenue growth since becoming an independent company. The animal health market benefits from long-term trends including rising pet ownership, increased spending on companion animals, and growing protein demand driving livestock product sales.

Zoetis Market Cap
Market capitalization reflects investor confidence in Zoetis growth prospects and market position. The company has maintained strong valuation since its 2013 IPO, benefiting from the attractive fundamentals of the animal health industry.
Zoetis Acquisitions
Strategic acquisitions have played an important role in expanding product portfolios and capabilities. Before the Zoetis spinoff, Pfizer Animal Health pursued aggressive growth through transactions between 2007 and 2011, acquiring companies like Fort Dodge Animal Health, Wyeth, and Alpharma. These deals significantly expanded the livestock and companion animal product lines.
As an independent company, Zoetis has focused on targeted acquisitions that strengthen core capabilities. The 2014 purchase of Abbott Animal Health assets brought anesthesia and pain management products. The 2018 Abaxis acquisition for $2 billion represented the largest deal, adding point-of-care diagnostics to the portfolio.
Recent transactions have emphasized innovation in companion animal health. The Nexvet acquisition in 2017 brought monoclonal antibody expertise, while the 2019 Platinum Performance purchase added nutritional products. The 2022 Jurox acquisition expanded the anesthetic portfolio with Alfaxan, and the 2023 Petmedix deal strengthened antibody therapy capabilities.
The acquisition strategy balances geographic expansion, product category diversification, and technology enhancement. This approach has enabled Zoetis to maintain market leadership while adapting to changing customer needs and scientific advances in animal health.
