David Charron

All filings by David Charron on record concern Quarterhill Inc. Over a trading history stretching from 17 June 2025 to 24 September 2026, the count stands at 11 filings.

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 latest filing, published on 25 September 2026, reports an option exercise in Quarterhill Inc. Typically, a trade is published a median of 7 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done. These figures are compiled from regulatory filings published by SEDI. They describe what insiders did and are not a recommendation.
