Merck & Co., Inc.
Could not find a ticker for this position, may be a filing error
A maker of prescription medicines and animal health products, Merck produces well-known drugs like the cancer treatment Keytruda and the HPV vaccine Gardasil, along with livestock and pet-care vaccines used by doctors, veterinarians, and farmers. Founded in 1891 as the American branch of a German family firm, the company was seized during World War I and later bought back, becoming an independent U.S. company that today goes by the name MSD outside North America. A fun quirk: its blockbuster Keytruda nearly got shelved — researchers originally set out to calm the immune system, not fight cancer.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last year: -356.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
