Vasquez Christian 4

What Happened
Christian Vasquez, Chief Financial Officer of BioAtla, had 1,802 shares withheld by the company on 2026-02-28 to satisfy tax withholding obligations tied to the vesting and net settlement of previously granted restricted stock units (RSUs). The withholding was recorded at $0.25 per share for a total of $445. This is a tax-withholding/net settlement event (code F), not an open-market sale by the insider.

Context
This is a routine tax-withholding/net-settlement action common when RSUs vest and does not indicate a voluntary sale or a change in insider sentiment. For investors tracking insider activity, purchases or open-market sales are generally more informative than withholding transactions, which are administrative.
