Nobody has researched this person's career yet, so founder and track record are left out of the score and of the total above.

Score = stake band (35) + founder (15) + tenure (10) + track record (15) + 12-month direction (−10…15) + filing discipline (10). An axis we have not researched is left out of the score and of the total it is shown over. Every input links to a filing or to our own research; the bands are ours.

Reported is every lot on the person's own Forms 3, 4 and 5 — direct and through trusts. Beneficial is the figure stated on the latest Schedule 13D/G cover page, which can exclude shares the person disclaims and include options exercisable within 60 days, so the two are never added together.

On the record with shareholders

Earnings calls

  1. Q4 FY2026 Aug 11, 2026 Liang's argument was that the June quarter's revenue shortfall and its record gross margin are the same fact seen twice: shipments slipped out of Q4 on customer power, cooling and networking readiness, which he called "purely a timing story," and the mix left behind was the higher-margin enterprise and CPU business. He spent the call promising that the mix is now deliberate rather than accidental — a bigger enterprise sales force, a maturing Data Center Building Block Solutions line with software and service attached, and an explicit willingness to decline low-margin GPU volume — while guiding fiscal 2027 to $65–$72 billion on over $60 billion of new orders. On funding he was blunt: the June $5.6 billion raise covers the plan, the ATM stays unused, and only revenue beyond $80 billion would require going back for more. Read the call · 8 quotes →
