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.

Each restricted stock unit ("RSU") represents a contingent right to receive one share of Issuer's Common Stock. The RSU vests in full on the earlier of: (i) May 20, 2027, and (ii) the Issuer's next annual stockholder meeting. These shares of Common Stock were automatically sold in a non-discretionary transaction to cover tax withholding obligations upon the settlement of certain time-based RSU awards. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $87.67 to $88.66, inclusive. The Reporting Person has provided to the Issuer and undertakes to provide to the staff of the Securities and Exchange Commission or any security holder of the Issuer, upon request, full information regarding the number of shares sold at each separate price within the range. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $88.71 to $89.67, inclusive.

Informational — no alert

Reason: tax_withholding. The filing footnotes identify tax withholding.
