Illumina, Inc. (NASDAQ:ILMN) is a diagnostics and research company that develops and markets integrated systems for analyzing genetic variation and biological function. Consequently, it provides sequencing- and array-based genetic and genomic analysis solutions. Having shed nearly 50% in market value over the past year, the struggling gene sequencing machine and chemical company has attracted the interest of activist investor Keith Meister.

The co-founder of Corvex Management has amassed a 2.5% stake in the company and has started agitating for changes as part of an activist campaign. Meister has already joined the company’s board form, where he is pushing for changes aimed at streamlining operations and increasing the focus on the core business.

The activist campaign comes from Illumina, Inc. (NASDAQ:ILMN), which is finding itself at a crossroads of a tariff fight between the US and China. Consequently, it has had to reduce its forecast for the year as it also plans to cut spending by up to $100 million.
