Dennis P. Calvert

Dennis P. Calvert, listed as chief executive, appears in our data through filings on Biolargo, Inc. shares, published by SEC (Form 4). Over a trading history stretching from 1 December 2016 to 30 September 2026, the count stands at 31 filings.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

The latest filing, published on 2 October 2026, reports a share grant of €66k in Biolargo, Inc. Typically, a trade is published a median of 2 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
