[Form 4] Liquidia Corporation Insider Trading Activity

Rhea-AI Filing Summary

Liquidia Corporation (LQDA) – Form 4 filing dated 15-Jul-2025 details two insider transactions by Chief Commercial Officer Scott Moomaw.

• 07-11-2025: 3,107 common shares were acquired through the conversion of vested performance stock units (Code M). This increased Moomaw’s direct holdings to 228,028 shares.
• 07-14-2025: 4,797 shares were sold at $14.28 per share (Code S) under a pre-arranged Rule 10b5-1 plan to cover tax obligations arising from recent RSU/PSU settlements. Post-sale, the executive directly owns 223,231 shares.

The filing also discloses a sizeable pipeline of unvested equity: 31,249 RSUs from a 2023 grant, 31,077 RSUs from a 2024 grant, and 69,729 RSUs granted in 2025. In addition, 11,002 shares were accumulated via the company’s 2020 ESPP.

No cash proceeds were reported for the acquisition; the sale generated roughly $68.5 k in gross proceeds. The net effect is a marginal reduction of 1,690 shares (<1% of the executive’s stake), suggesting a routine tax-related transaction rather than a directional view on Liquidia’s prospects.

Insights

Senior Securities Analyst

TL;DR: Minor tax-related sale; insider still retains >223 k shares – negligible impact on valuation.

The Form 4 shows Mr. Moomaw converting 3,107 PSUs and immediately disposing of 4,797 shares to settle tax liabilities under a 10b5-1 plan. The gross sale value (~$68 k) and the net share reduction (~0.7 % of his total holdings) are immaterial to the float and do not indicate strategic divestment. Importantly, the executive’s remaining equity plus 132 k unvested RSUs/PSUs continues to align his interests with shareholders. From a capital-markets perspective, this is routine insider activity with no signaling value regarding Liquidia’s fundamentals.
