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.

These shares were sold in multiple transactions at prices ranging from $296.84 to $297.75, inclusive. The reporting person undertakes to provide 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 within the ranges set forth in footnotes (3) through (9) to this Form 4.

The shares are held of record by the 2026 Seifert Grantor Retained Annuity Trust dated May 27, 2026, for which the reporting person serves as trustee. The shares subject to the Performance Stock Option are comprised of nine separate tranches that become eligible to vest upon achievement of certain stock price targets (the "Stock Price Goals"). Upon satisfaction of a Stock Price Goal, 1/6 of the shares subject to the applicable tranche vests and becomes exercisable on each Issuer quarterly vesting date (2/15, 5/15, 8/15 or 11/15) occurring on or after the date of certification of achievement of the applicable Stock Price Goal for such tranche. As of the date of this report, six of the nine stock price goals have been satisfied and the underlying shares vest as set forth above. The remaining three tranches, representing 277,500 shares subject to the Performance Stock Option, become eligible to vest upon achievement of the applicable Stock Price Goal.
