Dr. Mark H. Rachesky: trading record in brief

This profile gathers the share dealings of Dr. Mark H. Rachesky across 3 companies, led by Starz Entertainment Corp., Lionsgate Studios Corp. and Telesat Corporation. We count 55 filings; the first trade dates from 15 September 2009 and the latest from 5 October 2026.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The latest filing, published on 9 October 2026, reports a share grant in Telesat Corporation. Filings reach the SEDI feed a median of 5 days after the trade. This delay matters because a trade only becomes useful information once it is public. This summary is built from SEDI disclosures alone and does not predict where the share price will go.
