Overview
Perrigo Company plc is a healthcare manufacturer and branded self-care business with origins in Allegan, Michigan. Founded in 1887 by brothers Luther and Charles Perrigo as a general store, the company developed from a supplier of inexpensive store-brand remedies into a multinational producer and marketer of over-the-counter medicines, generic prescription products, nutritional products, consumer wellness goods, and active pharmaceutical ingredients. Its historical business model has emphasized supplying retailers and pharmacies with private-label products that are sold under store brands, while acquisitions have progressively expanded Perrigo's geographic reach, therapeutic coverage, and portfolio of recognized consumer healthcare brands. The company entered the public markets with an initial public offering on Nasdaq in 1991. Its international expansion accelerated through acquisitions, including Galpharm Healthcare in the United Kingdom, Orion Laboratories in Australia and New Zealand, PBM Holdings in infant nutrition, Rosemont Pharmaceuticals in specialty and generic oral liquids, and Omega Pharma in Belgium. The 2005 acquisition of Israel-based Agis Industries was particularly important in establishing Perrigo as a broader generic pharmaceuticals company. Mori Arkin, who had built Agis from his family's drug-import business, became a major shareholder and vice chairman after the transaction. Perrigo's corporate structure changed substantially through its 2013 acquisition of Irish pharmaceutical company Elan Corporation. The transaction enabled Perrigo to become Irish-registered for tax purposes, while its principal executive and operational presence remained in Michigan. The reorganization was widely discussed as a corporate tax inversion because most of the company's sales were generated through the United States healthcare system. The structure later became the subject of a major dispute with the Irish Revenue Commissioners concerning capital-gains tax associated with Elan's sale of its interest in the Tysabri multiple-sclerosis medicine before Perrigo acquired Elan. In 2015, Perrigo rejected an unsolicited acquisition proposal from Mylan valued at approximately $29 billion. The episode became one of the defining strategic contests in the company's history and was followed by investor litigation alleging that statements made during the bid influenced shareholders. Perrigo subsequently experienced leadership changes and continued to reshape its portfolio. It sold its generic pharmaceuticals business to Altaris Capital Partners in 2021, reflecting a strategy to concentrate more heavily on consumer self-care and branded healthcare. The acquisition of HRA Pharma, completed in 2022, strengthened this focus by adding consumer products in women's health, emergency contraception, and other self-care categories. Perrigo currently operates across consumer self-care and pharmaceutical activities. Its product categories include pain relief, cough and cold, allergy and sinus care, gastrointestinal remedies, smoking cessation, first aid, antacids, feminine care, vitamins and supplements, oral care, dermatological products, and other wellness products. The company also manufactures products for retailers and pharmacies that are sold under private labels, making it an important behind-the-scenes supplier in consumer healthcare. Its branded portfolio includes products developed or acquired through international consumer-health businesses, including HRA Pharma. The company moved its corporate headquarters from Allegan to downtown Grand Rapids in June 2022, while retaining manufacturing and other operations at the Allegan campus. In 2023, HRA Pharma received U.S. Food and Drug Administration approval for Opill, a progestin-only oral contraceptive that became the first nonprescription daily birth-control pill approved for sale in the United States. The approval represented a major milestone for Perrigo's consumer-health strategy and expanded its role in accessible women's healthcare. Perrigo remains legally associated with Ireland while maintaining substantial American operations and a business model centered on accessible self-care, private-label manufacturing, and selected consumer healthcare brands.
History
Perrigo began in 1887 in Allegan, Michigan, where Luther and Charles Perrigo operated a general store. The business gradually developed around supplying affordable medicinal products and eventually became a major manufacturer of store-brand healthcare goods. Its private-label model allowed retailers and pharmacies to market medicines under their own names while relying on Perrigo for formulation, manufacturing, packaging, and regulatory support. The company went public on Nasdaq in 1991. During the 2000s, it expanded beyond its original American base through a sequence of acquisitions. In 2005 it bought Agis Industries, an Israel-based generic pharmaceutical company founded and developed by Mori Arkin. The transaction added generic drug capabilities and gave Arkin a significant stake in Perrigo, along with a vice-chairmanship. Perrigo then acquired businesses in the United Kingdom, Mexico, Australia, New Zealand, infant nutrition, pediatric care, feminine hygiene, and other consumer categories. Among the notable transactions were Galpharm Healthcare in 2008, Orion Laboratories in 2010, PBM Holdings in 2010, Rosemont Pharmaceuticals in 2013, and the assets of Sergeant's Pet Care Products as Perrigo explored animal wellness. Rosemont strengthened the company's specialty and generic oral-liquid business. The 2013 acquisition of Elan Corporation was strategically and financially consequential. Elan was headquartered in Ireland, and the transaction allowed Perrigo to reincorporate there for tax purposes while retaining its principal executive base and major operational presence in Michigan. The arrangement was criticized as a tax inversion because the majority of Perrigo's sales were connected to the United States. Perrigo's strategic independence was tested in 2015 when Mylan made an unsolicited offer worth approximately $29 billion. Perrigo rejected the proposal, and shareholders did not approve the combination. Joseph Papa, who had led the response to the bid, later left Perrigo to become chief executive of Valeant. John Hendrickson then assumed expanded leadership responsibilities. He was followed by Uwe Roehrhoff and, later in 2018, Murray S. Kessler. The tax structure created through Elan became the focus of a major Irish dispute in December 2018. The Irish Revenue Commissioners asserted that Perrigo owed approximately €1.64 billion in capital-gains tax connected with Elan's earlier sale of Tysabri to Biogen. Perrigo argued that the transaction represented ordinary trading activity and should receive different tax treatment. The announcement was followed by the sharpest one-day decline in Perrigo's share price described in the company's history and intensified scrutiny of the tax inversion. Perrigo continued to adjust its portfolio. It acquired Omega Pharma in 2015, adding European consumer-health brands, and later expanded oral care through Ranir Global Holdings and selected assets of High Ridge Brands. In 2021, Perrigo agreed to sell its generic pharmaceuticals business to Altaris Capital Partners for approximately $1.55 billion, signaling a stronger emphasis on consumer self-care. It then agreed to acquire HRA Pharma from Astorg and Goldman Sachs Asset Management for approximately $2.1 billion. The transaction closed in 2022 and brought products in women's health, emergency contraception, and other consumer categories into Perrigo's portfolio. In June 2022, Perrigo moved its corporate headquarters from Allegan to downtown Grand Rapids, Michigan, while continuing to maintain manufacturing and other operations at the Allegan campus. In 2023, HRA Pharma's Opill received FDA approval for over-the-counter sale in the United States. Opill's approval marked a significant development in the company's strategy of making healthcare products more accessible without a prescription. Perrigo's present identity therefore combines its historic role as a private-label supplier with an expanding portfolio of branded consumer self-care products and selected pharmaceutical capabilities.
