Founded in 1985, Marlborough, Massachusetts–based Hologic develops and manufactures diagnostics products, imaging systems, and surgical products. It focuses on women's health and well-being through early detection and treatment. The company successfully pivoted toward more general diagnostics during the COVID-19 pandemic, becoming a major provider of tests and testing machines for the novel coronavirus. The resulting influx of cash enabled Hologic to reactivate full-time R&D operations and send business development teams shopping for M&A opportunities. In 2022, Hologic opened an innovation center in Aix-en-Provence, France, launched new assays for COVID-19, flu and RSV, and continued to exceed Wall Street’s expectations despite declining demand for COVID-19 assays and semiconductor shortages affecting the company’s Breast Health business. –JH

*The 2022 Big 100 report is moving to September versus November in previous years. Because its fiscal year ends in September, Hologic's revenue number is the same as in the 2021 report.
