Carl Icahn says new Illumina CEO has his 'full support'
Neilson Barnard
Illumina investor Carl Icahn said Wednesday via X that the companyâs incoming CEO, Jacob Thaysen, has his âfull support.â
âI spoke to Illuminaâs new CEO, Jacob Thaysen. I think he will do an excellent job and he has my full support,â Icahn posted on X, formerly known as Twitter.
Illumina announced earlier this week that it had hired Thaysen as its new CEO, succeeding Charles Dadswell, who has been serving as interim CEO since the resignation of Francis deSouza earlier this year. Dadswell will return to his position of general counsel once Thaysen assumes the CEO post on Sept. 25.
Prior to taking the top job at Illumina, Thaysen was president of Agilent Technologiesâ (A) Life Sciences and Applied Markets Group.
Francis deSouza stepped down as CEO in June after surviving a board battle with Icahn, who had called for his removal in part over Illuminaâs decision to acquire cancer diagnostics developer Grail despite regulatory concerns.
