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 shares of common stock issued upon vesting of 25% of the restricted stock units granted on August 15, 2025. Represents shares of common stock sold to satisfy certain tax withholding obligations with the vesting of the restricted stock units. Each restricted stock unit represents the right to receive, upon vesting, one share of the Issuer's common stock in accordance with the Issuer's 2020 Omnibus Incentive Compensation Plan. The restricted stock units were granted on August 15, 2025 as part of the Issuer's incentive program to the Reporting Person. The restricted stock units granted on August 15, 2025 vest annually at a rate of 25% on each anniversary of the grant date, commencing on the first anniversary of the grant date.

Raspberry interpretation
Informational — no alert

Reason: tax_withholding. The filing footnotes identify tax withholding.
