Maravai Lifesciences Holdings, Inc.
A maker of the raw ingredients behind mRNA vaccines and therapies, Maravai LifeSciences supplies everything from its CleanCap® capping technology to impurity-detection kits used by biopharma and diagnostics companies in roughly sixty countries through its TriLink and Cygnus brands. Formed in 2014 by Carl Hull, Eric Tardif, and the private-equity firm GTCR, it grew by buying scientifically driven companies like TriLink and Cygnus. Its CleanCap® technology was a key ingredient in the Pfizer-BioNTech COVID-19 vaccine, and its name is the northern Italian word for "miracle."

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 all recorded history: -9.08M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
