Intel’s stock climbed over 1% in pre-market trading Friday, extending Thursday’s near-15% rally after the company named Lip-Bu Tan its new CEO. The appointment ends over three months of leadership uncertainty following Pat Gelsinger’s forced retirement in December.

Lip-Bu Tan may be one of the most powerful technology executives you've never heard of. As he steps into one of the highest-profile jobs on the planet, CEO of troubled, storied chipmaker Intel, his performance will be on full display.

Intel ( INTC) named Lip-Bu Tan its new CEO, sending the chipmaker's stock higher in after-hours trading Wednesday. Tan, who is set to take the helm of Intel as of next Tuesday, is the former CEO of Cadence Design Systems ( CDNS ), a semiconductor software company that counts Intel among its partners.
