Brifo Victoria 4

What Happened
Victoria Brifo, a director of Trinseo PLC, recorded a disposition of 42,484 shares on May 12, 2026 identified as an "other acquisition or disposition" (transaction code J). The filing indicates these were a voluntary forfeiture of restricted stock units (RSUs) previously granted on June 25, 2025; the RSUs were unvested and unsettled at forfeiture. No price or cash value was reported for the transaction.

• Shares affected: 42,484 RSUs forfeited. Price: N/A (no cash proceeds).

Context
A forfeiture of unvested RSUs cancels future rights to receive shares and does not involve an open-market sale or proceeds; it therefore doesn't provide a direct market-value signal like a purchase or sale would. Transaction code J is used for other types of acquisitions/dispositions (here, forfeiture).
