Suzano (SUZ) VP Marcos Assumpcao Receives and Sells Phantom Shares

What Happened
Marcos Moreno Chagas Assumpcao, Vice President of Finance and Investor Relations at Suzano (SUZ), had 9,304 cash‑settled phantom shares vest and be disposed to the issuer (settled in cash) on 2026-03-30, and on the same date received a new grant of 9,497 phantom shares. The Form 4 lists per-share price and total cash value as N/A; the filing’s footnotes state the phantom awards are referenced to Suzano common shares and are settled in cash upon vesting.

Context
These were derivative (phantom/share‑equivalent) awards that settle in cash based on Suzano’s stock price on vesting—not open‑market purchases or direct sales of common stock. A cash settlement upon vesting is different from an insider selling shares on the market; it reflects plan payout mechanics rather than an immediate transfer of company stock. No dollar amounts were disclosed in the Form 4.
