A Form 4 is filed within two business days of a company insider — an officer, a director, or a holder of more than ten percent of the stock — changing their position in the shares. All 14 filings in this group are Form 4s for Maravai LifeSciences Holdings, Inc.
The difficulty with reading these filings as a group is that a single form type covers transactions that mean entirely different things. An executive spending their own money to buy stock and an executive having shares withheld to pay tax on a vesting grant both appear as a Form 4. Every filing below is therefore tagged with the nature of the underlying transaction, taken from the transaction code reported on the form itself.
Across the 14 insider filings shown, the breakdown is 9 tax withholding, 3 compensation award, 1 gift and 1 open-market sale. 1 of them involved a discretionary open-market trade; the rest are compensation and administrative mechanics.

MRVI insider ORESHACK KURT (General Counsel) sold 50,000 shares (~$254.0K)
ORESHACK KURT, listed as General Counsel at MARAVAI LIFESCIENCES HOLDINGS, INC., reported an open-market sale of 50,000 MRVI shares in a Form 4 filing. This is a confirmed insider sale, not just a proposed sale notice.
The insider sold shares on the open market. Sales may be discretionary or executed automatically under a pre-arranged Rule 10b5-1 trading plan, and a Form 4 does not always make clear which applies.
