In 2007, the company acquired five divested drugs from Mylan which Mylan was forced to sell as part of their acquisition of the generics unit of Merck KGaA.[4] At this time, the company was noted as being a private company based in Paterson, New Jersey.[4]
After the 2007 acquisition of Akyma Pharmaceuticals, a Glasgow, Kentucky-based regional distributor, Amneal launched its own product label.[5]
In 2008, the company expanded into India with the development of an R&D Centre in Gujarat.[6] Continued expansion in the United States occurred between 2010 and 2016 in New Jersey, New York and Kentucky.[7][8] As of 2017, the company had grown much of its physical footprint and product base through a series of acquisitions, including the acquisition of assets from Pfizer, Actavis and Warner Chilcott.[3]
In 2018, Amneal Pharmaceuticals LLC merged with Impax Laboratories, Inc. to form Amneal Pharmaceuticals, Inc. Shares of newly public AMRX began trading on the NYSE on May 7, 2018.[9] Concurrent with the Impax merger, Amneal acquired Gemini Laboratories for $117 million, including Unithroid, Gemini's lead product for treating hypothyroidism.[10]
In December 2019, Amneal announced it had entered into an agreement to acquire a majority interest in AvKARE, a private label provider of generic pharmaceuticals in the US federal agency sector. Under the agreement, AvKARE would continue to operate as an independent subsidiary of Amneal.[11]
