Form 4 raw → Raspberry

The value is in what we do not call a signal.

The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

Represents earned non-derivative performance stock units of Constellium SE (the "Issuer") granted on March 9, 2023 that contained performance-vesting requirements, which vested on March 9, 2026. The Reporting Person sold 4,614 ordinary shares of the Issuer upon the vesting of restricted stock unit and performance stock unit awards previously granted on March 9, 2023, solely to satisfy tax withholding obligations incurred upon vesting.

Raspberry interpretation
Informational — no alert

Reason: tax_withholding. The filing footnotes identify tax withholding.
