Matthew Blank: trading record in brief
This profile gathers the share dealings of Matthew Blank across 3 companies, led by Cumulus Media Inc, CuriosityStream Inc. and AMC Global Media Inc. Between 4 May 2021 and 4 February 2026, the trades on record add up to 11 filings.

The newest entry dates from 6 February 2026: an option exercise, in CuriosityStream Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
