Illumina, Inc. is a multinational corporation headquartered in San Diego, California, that specializes in DNA sequencing and array-based technologies. Founded in 1998, the company has established itself as a leader in the field, developing, manufacturing, and marketing integrated systems for the analysis of genetic variation and biological information.
In 2024, Illumina was removed from the S&P 500 due to a combination of factors. The company faced intense competition from other DNA sequencing companies, which led to a decline in market share and profitability. Additionally, regulatory challenges and legal disputes with competitors further hindered Illumina's growth and expansion plans. Despite these setbacks, Illumina remains a prominent player in the DNA sequencing market, continuing to innovate and develop cutting-edge technologies.
