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 9 filings in this group are Form 4s for Viridian Therapeutics, 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 9 insider filings shown, the breakdown is 6 compensation award, 1 option exercise, 1 open-market purchase and 1 open-market sale. 2 of them involved a discretionary open-market trade; the rest are compensation and administrative mechanics.
