AMD (Advanced Micro Devices)

AMD's resurrection under CEO Lisa Su is one of the great corporate turnaround stories of the modern era — from near-bankruptcy in 2014 to a $250B market cap company that now outperforms Intel CPUs on virtually every benchmark. Its EPYC server processors have captured 25%+ of the lucrative data center CPU market, displacing Intel across major hyperscaler deployments at AWS, Google, and Microsoft. The Instinct MI300X GPU accelerator is AMD's direct bid for NVIDIA's AI market, and its 2023 acquisition of Xilinx ($49B) added reconfigurable FPGAs to its portfolio. Lisa Su's transformation of AMD is covered in the Harvard Business Review case 'AMD: The Turnaround' and she was Fortune's Businessperson of the Year 2019.
