Sankar Shyam

Director · Officer · PLTR, DNA

As of 2026-09-16, Sankar Shyam has 206 Form 4 transactions on record across 2 companies — 66 in the trailing 12 months.

Everything this person has disclosed to the SEC on Form 4 — across every company they file for — reconstructed from the public record. A filing history, not a tip sheet.

Pattern in the record: open-market sales filed in August in multiple years since 2025 — a recurring calendar cadence, more consistent with scheduled activity than a one-off decision.
