Gerald R. Cysewski: trading record in brief
Gerald R. Cysewski (chief executive) discloses dealings in Cyanotech Corp to SEC (Form 4). We count 12 filings; the first trade dates from 13 July 2021 and the latest from 29 July 2025.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.
The newest entry dates from 31 July 2025: an option exercise, in Cyanotech Corp. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
