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.

The sale was effected pursuant to a Rule 10b5-1 instruction letter entered into on August 8, 2025 to satisfy the Reporting Person's tax withholding obligation upon the vesting of previously granted equity awards. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $30.97 to $31.96, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price at which the transactions were effected. Includes shares to be issued in connection with the vesting of one or more restricted stock units.
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.
