Brown Michael Jon 4

What Happened Michael Jon Brown, Executive Vice President and Chief Legal Officer of DexCom, received a grant of 39,019 restricted stock units (RSUs) on March 8, 2026 (reported as an award at $0.00). On the same date, 23,325 shares were withheld by the issuer to satisfy tax withholding obligations at a reported value of $68.10 per share, totaling $1,588,432. The withholding is reported as a disposition for tax purposes but, per the filing, does not represent an open-market sale by Mr. Brown.

Context RSUs are awards that convert to shares upon vesting; this grant is a compensation award rather than a market purchase. Net settlement/withholding of shares to cover taxes is a routine administrative step and should not be read as an intention to liquidate holdings. The filing shows forthcoming vesting over multiple years, meaning the recipient will only receive shares as those RSUs vest.
