Clack Amy 4

What Happened

• Amy Clack, Chief Administrative Officer of Tradeweb Markets (TW), had 1,128 shares of Class A common stock withheld to satisfy tax withholding related to the settlement of restricted stock units (RSUs). The withholding was executed at $126.17 per share, a total value of approximately $142,320 (reported as a disposition, transaction code F). Separately, she was credited with 3 shares (transaction code A) in connection with settlement of dividend equivalent rights (DERs) tied to previously awarded RSUs; those 3 shares were acquired at no cash cost.

Context

• The 1,128-share disposition reflects routine tax withholding on equity compensation (not an open-market sale intended as a directional bet). The small DER award (3 shares) is a settlement related to those RSUs. Such withholding transactions are common when equity grants vest and generally should not be interpreted as a signal of insider sentiment.
