Greifeneder Bernd

Officer · DT

As of 2026-09-16, Greifeneder Bernd has 219 Form 4 transactions on record across 1 company — 140 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.
