Michael G. Grey: trading record in brief
Filings by Michael G. Grey span 3 companies, the busiest being Mirum Pharmaceuticals, Inc., Horizon Therapeutics Public Ltd Co and OnKure Therapeutics, Inc. In total, 14 filings cover trades dated from 22 July 2021 to 19 December 2025.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
The newest entry dates from 23 December 2025: an option exercise of €125k, in Mirum Pharmaceuticals, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
