Former Nvidia adviser claims $1 billion in unvested stock over 1996 vesting dispute

Eric Gullichsen, who served on Nvidia's Technical Advisory Board from 1993 to 1996, says he was granted 25,000 stock options but only 15,625 vested before he left, due to a discrepancy over whether his options were meant to vest quarterly or annually. He argues that after 30 years of stock splits, the missing 9,375 options would now be worth roughly $1 billion, and he is disputing Nvidia's account of the vesting terms.

Early NVIDIA advisor says he is owed roughly $1 billion in unpaid stock options

A former technical advisor to NVIDIA, who worked with the company in 1993 on biquadratic texture mapping for its first graphics chip, says he recently discovered he was granted 25,000 stock options that appear never to have been exercised or paid out. He describes helping port his rendering technique to NVIDIA's early hardware and demonstrating it publicly before Microsoft's DirectX standard favored triangle-only rendering, which he says hurt NVIDIA's early business.
