SEC filings show Dropbox Chief Legal Officer William T. Yoon disposed of 16,833 Class A shares on Aug. 17 in a non-discretionary transaction valued at about $579,000.
The shares were withheld by Dropbox to satisfy tax remittance obligations triggered by the vesting of restricted stock units, rather than sold at the executive's discretion.
350,130 shares remained in Yoon's direct ownership after the transaction, a stake worth about $11.7 million based on Dropbox's Aug. 17 closing price.
RSUs scheduled to vest through Feb. 15, 2030 leave Yoon with ongoing equity exposure to Dropbox, which had an $8.6 billion market value and $2.5 billion in trailing revenue.
