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.

Following an administrative correction to the number of shares withheld by the Issuer to satisfy the Reporting Person's tax withholding obligations in connection with the vesting of restricted stock units on April 1, 2026, as reported on a Form 4 filed on April 3, 2026, an additional 16 shares were sold on April 8, 2026 pursuant to a sales plan adopted by the Reporting Person on November 25, 2025 and intended to comply with Rule 10b5-1 under the Securities Exchange Act of 1934.
Raspberry interpretation
Informational — no alert
Reason: tax_withholding. The filing footnotes identify tax withholding. The trade is reported under a Rule 10b5-1 plan.
Recent transactions
Voluntary purchases and sales; administrative noise stays hidden.
