Intel CEO Pat Gelsinger has retired, the struggling chipmaker said Monday in a surprise announcement. Two company executives, David Zinsner and Michelle Johnston Holthaus, will act as interim co-CEOs while the company searches for a replacement for Gelsinger, who also stepped down from the company's board.

David Zinsner and Michelle Johnston Holthaus were named interim co-leaders after the boomerang executive, who returned to the company in 2021, left the top job.
