5 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.

Transaction effected pursuant to a Rule 10b5-1 plan adopted by the Reporting Person on December 15, 2023. These shares of common stock were sold to cover taxes associated with the settlement of restricted stock units ("RSUs") that were initially granted to the Reporting Person on January 25, 2023. Includes (i) 3,125 unvested restricted stock units ("RSUs") of the 50,000 RSUs granted to the Reporting Person on January 25, 2023, (ii) 17,838 unvested RSUs of the 57,085 RSUs granted to the Reporting Person on January 11, 2024, (iii) 28,609 unvested RSUs of the 50,861 RSUs granted to the Reporting Person on January 11, 2025, (iv) 17,187 unvested RSUs of the 25,000 RSUs granted to the Reporting Person on July 1, 2025, (v) 23,728 RSUs granted to the Reporting Person on January 16, 2026, none of which have vested as of the date of this Form 4 and (vi) 4,368 shares acquired under the Liquidia Corporation 2020 Employee Stock Purchase Plan.

Raspberry interpretation
Informational — no alert

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