Sona Nanotech Inc.: what insiders have been doing
This page follows insider dealings at Sona Nanotech Inc. as filed with SEDI. From 24 October 2025 to 24 October 2026, the disclosure feed for Sona Nanotech Inc. logged 16 filings by 10 insiders.
Every open-market trade in the period is a purchase: 1 purchase worth €3,557, from 1 insider, and not a single sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The largest single trade was a purchase of €3,557 by Regan, David A., published on 20 March 2026. On the buying side, the filings list 1 senior executive among the declarants.
For context, the typical company on the same exchange (median of 2,734 companies) published 14 filings over the same period, against 16 filings here. The full history, which starts in 2018, counts 28 purchases against 8 sales.
The last purchase on record was published on 20 March 2026, which is 219 days ago. Filings reach the SEDI feed a median of 2 days after the trade. Until a filing is published, the market cannot know about the trade.
Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
