Barnett Valerie 4

What Happened
Valerie Barnett, Chief Legal Officer of Cytek Biosciences (CTKB), had 1,346 restricted stock units (RSUs) convert into 1,346 shares on February 18, 2026. To satisfy tax withholding on the vesting, 525 of those shares were withheld and surrendered to the company at an indicated value of $4.20 per share, totaling $2,205. This was a vesting/conversion of RSUs (award) rather than an open-market buy or sell.
