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 the number of common stock required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of certain Restricted Stock Units ("RSUs"). The sale was to satisfy tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary transaction by the Reporting Person. The RSUs were originally granted on June 3, 2025 under the Issuer's 2025 Equity Incentive Plan, the vesting of which were subject to the Reporting Person's continued service with the Issuer through the vesting date. On December 3, 2025, the RSUs vested as a result of the Reporting Person's continued service with the Issuer through the vesting date. This transaction was executed in multiple trades during the day at prices ranging from $27.6200 to $27.7500. The weighted-average price is reported above. The reporting person hereby undertakes to provide upon request to the SEC staff, the issuer or a security holder of the issuer full information regarding the number of shares and prices at which the transactions were effected.

Raspberry interpretation
Informational — no alert

Reason: tax_withholding. The filing footnotes identify tax withholding.
