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.

The stock options vest in full on September 14, 2027, subject to continued service on the Company's Board of Directors through such date and to earlier vesting in certain circumstances described in the Company's Non-Employee Director Compensation Policy as in effect on the date of grant. Each restricted stock unit ("RSU") represents a contingent right to receive one share of the Company's common stock. The RSUs vest in full on September 14, 2027, subject to continued service on the Company's Board of Directors through such date and to earlier vesting in certain circumstances described in the Company's Non-Employee Director Compensation Policy as in effect on the date of grant.
