ALVARADO JOSEPH 4

What Happened

• Joseph Alvarado, a director of Trinseo PLC (TSE), recorded a disposition on May 12, 2026 consisting of 42,484 shares. The filing shows this as a voluntary forfeiture of restricted stock units (RSUs) rather than an open-market sale, so no price or proceeds are reported.

Key Details

• Transaction date: 2026-05-12 (reported on Form 4 filed 2026-05-14 — timely filing)
• Shares affected: 42,484 RSUs forfeited
• Price / proceeds: N/A (forfeiture of unvested award; not a market sale)
• Shares owned after transaction: Not specified in the filing
• Transaction code: “J” (other acquisition/disposition) — here used for forfeiture
• Footnote: The RSUs were granted on June 25, 2025 and were unvested/unsettled at the time of forfeiture (voluntary)

Context

• This was a forfeiture of unvested equity, not a sale, so it does not directly indicate insider selling for cash. For retail investors, purchases or market sales by insiders are generally more informative about sentiment; forfeitures usually reflect grant terms, employment changes, or personal decisions and do not generate proceeds for the insider.
