- Executive Transaction Overview: Kathleen Goin, COO of Palvella Therapeutics, exercised 4,302 options and immediately sold an equivalent number of common shares on March 18, 2026, with a transaction value of approximately $508,000 based on a weighted average purchase price of $117.99 per share, indicating a liquidity-driven decision by the executive.
