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.

Restricted Stock Units convert into common stock on a one-for-one basis. The transaction represents an automatic sale to satisfy the tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary trade by the Reporting Person. The shares underlying the restricted stock unit award shall vest as to 25% of the shares on June 20, 2025 and as to 1/16th of the underlying shares on each quarterly anniversary of such date thereafter, while the grantee remains a service provider to the Company. The shares underlying the restricted stock unit award shall vest as to 1/16th of the shares on June 20, 2025 and as to 1/16th of the underlying shares on each quarterly anniversary of such date thereafter, while the grantee remains a service provider to the Company.

Raspberry interpretation
Informational — no alert

Reason: tax_withholding. The filing footnotes identify tax withholding.
