Rita A. Karachun

Rita A. Karachun, listed as finance chief, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Merck & Co., Inc. and Coherus Oncology, Inc. We count 37 filings; the first trade dates from 6 May 2016 and the latest from 5 June 2026.

Every open-market trade on record is a sale: 3 sales worth €5.0M. Besides market trades, the filings include 15 share grants and 19 option exercises.

The record was last updated on 9 June 2026 with a share grant in Coherus Oncology, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
