SummaryUpdated Jun 1, 2026

ProPhase Labs, Inc. (NASDAQ:PRPH) is a healthcare company founded in 1989 and formerly known as The Quigley Corporation. Based in Garden City, New York, the company has undergone significant transformation from its origins as a manufacturer of over-the-counter consumer healthcare products to a diversified healthcare enterprise with operations spanning diagnostic services, genomics, manufacturing, and pharmaceutical development. The company went public in 1994 and has evolved through various strategic pivots, most notably expanding into COVID-19 testing during the pandemic and subsequently diversifying into genomics and cancer diagnostics as pandemic-related revenues declined.
