Illumina Responds to Icahn Partners' Nomination of Directors

Upon receipt of Icahn Partners' nominations, Illumina's independent Chairman of the Board, John Thompson, and Chief Executive Officer, Francis deSouza, engaged in multiple conversations with Carl Icahn. Illumina's Nominating/Corporate Governance Committee also met with the three nominees. Mr. Icahn was explicit and unyielding in his demand that any resolution should give him outsized influence and control. The Board has determined Icahn's nominees lack relevant skills and experience, and that it is not in the best interests of shareholders to appoint Mr. Icahn's three nominees to the Board of Illumina. The Board recommends that shareholders not support Mr. Icahn's nominees.
