The story
Exact Sciences was founded in 1995 in Marlborough, Massachusetts, by Stanley Lapidus and Anthony Shuber as a company focused on the development of a non-invasive test for colorectal cancer. The company eventually went public with an initial offering on the NASDAQ in 2001. In the early years, there was much speculation that the company would be acquired by a competitor or exit the market; during this time the company's share price fell to less than one dollar.
A significant turnaround in the company's fortunes began with the announcement of a mutual collaboration and licensing agreement between Exact Sciences and the Mayo Clinic in June 2009. In the same year, the company appointed Kevin Conroy as CEO & president and moved its head office to Madison, Wisconsin.
In August 2014, Exact Sciences received premarket approval from the Food and Drug Administration for the use and marketing of its flagship product, Cologuard. This breakthrough heralded the beginning of a period of rapid growth for Exact Sciences and the start of its first foray into the acquisitions market.
In August 2017, the company made its first major acquisition when it purchased Sampleminded, a healthcare information technology company based in Salt Lake City, Utah, for $3.2 million. This was followed by the January 2018 announcement that Exact Sciences had completed a $690 million convertible bond offering and the revelation that the company was to acquire Armune Bioscience, a cancer diagnostic developer based in Kalamazoo and Ann Arbor, Michigan (announced during that year's J.P Morgan Healthcare Conference). Third-quarter financial reports revealed the price of the Armune Bioscience acquisition to be valued at $12 million, plus $17.5 million in incentives for certain milestones. Later, in October 2018, Exact Sciences announced its purchase of Biomatrica, a developer of sample preservation technology based in San Diego, California.
In summer 2019, Exact Sciences opened a new 169,000 square feet lab and warehouse facility to expand its testing capacity for Cologuard and, in its largest acquisition yet, announced its intention to buy Genomic Health, a genetic cancer detection company based in Redwood City, California, for $2.8 billion. The reason given for this latest acquisition was to both expand Exact Sciences' product portfolio through the addition of Genomic Health's OncotypeIQ suite of precision tests, and expand into other markets outside the US on the back of Genomic Health's existing network.
In March 2020, Exact Sciences purchased Paradigm Diagnostics and Viomics, two companies based in Phoenix, Arizona that would expand their lab testing and research and development capabilities. Later, in October 2020, the company again announced a round of acquisitions - this time of Thrive Earlier Detection Corp. (based in Cambridge, Massachusetts) and Base Genomics (based in Oxford, England), two companies specializing in one of Exact Sciences' pipeline areas - blood-based cancer screening.
Exact Sciences responded to the 2020 COVID-19 pandemic by temporarily refocusing a portion of its diagnostic capacity to testing for the disease. The company received FDA regulatory approval to provide home testing kits in April 2020, becoming one of the first companies in the U.S. to do so.
In early 2021, Exact Sciences announced its acquisition of Ashion Analytics and plans to collaborate in research with TGen, the City Of Hope's Genomics Institute. This news came shortly after the company's decision to purchase an exclusive-use license of TGen's proprietary liquid biopsy-based test technology, Tardis.
