DEF 14 Inc. June 12, 2023


In a dramatic turn of events, Francis deSouza, the CEO of Illumina Inc., has tendered his resignation, following an extended and highly contentious battle with prominent investor Carl Icahn. For those unfamiliar with the story, here's a simplified rundown:

  • Initially, deSouza managed to hold his ground against Icahn's aggressive moves, as he successfully secured re-election to Illumina's board of directors, along with seven other members.

  • However, Icahn gained an upper hand during the recent shareholders' meeting, when his nominee, Andrew Teno, secured a position on the board.

  • DeSouza, acknowledging the shifting tides, made the difficult decision to step down as CEO. In a heartfelt letter to the company's employees, he expressed gratitude for their support and pride in the accomplishments they achieved together.

  • To ensure a smooth transition, Charles Dadswell, the senior vice president and general counsel, has been appointed as interim CEO, while the company actively searches for a suitable replacement.

  • DeSouza will remain involved in an advisory capacity until the end of July, offering guidance during this critical period.
