3 sellers account for the net balance. There is no cluster of three distinct buyers within 30 days. We found no CEO/CFO purchases over 12 months.

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 shares automatically sold pursuant to an irrevocable sell to cover election entered into upon acceptance of the grant to satisfy tax withholding obligations in connection with the vesting of the 25,000 RSUs from an August 1, 2025 grant of 75,000 RSUs. Includes 162 shares of common stock acquired under the Issuer's employee stock purchase plan for the period ended June 30, 2026.

Raspberry interpretation
Informational — no alert

Reason: tax_withholding. The filing footnotes identify tax withholding. The trade is reported under a Rule 10b5-1 plan.
