Sabesp (SBSP3) CPO Bressane Junior Receives RSUs; 7,371 Vest, 2,027 Withheld

What Happened Bressane Junior, Chief People Officer of Companhia de Saneamento Básico do Estado de Sao Paulo (Sabesp, ticker SBSP3), had 7,371 restricted stock units (RSUs) vest on May 1, 2026. Those RSUs converted to common shares (reported as derivative conversion, code M). To satisfy tax withholding obligations (code F), 2,027 of the vested shares were withheld/disposed at an effective price of $6.69, yielding $13,561. Net shares delivered to the insider from this vesting: 7,371 − 2,027 = 5,344 shares.

Context This was an RSU vesting event (conversion of restricted units into shares) with shares withheld to cover tax liabilities—a routine administrative outcome rather than an open-market buy or sell. For retail investors, vesting/withholding entries mainly reflect compensation mechanics; they do not necessarily indicate the insider is buying or selling stock for investment reasons.
