Context
As a 10% owner, Duca is a large shareholder rather than necessarily an executive; sales under a 10b5‑1 plan are pre‑arranged and commonly used to avoid timing issues tied to inside information. Such routine plan‑based sales are factual disclosures of liquidity events rather than direct indicators of company outlook. Retail investors should consult the full Form 4s (both filings) for post‑transaction holdings and any additional details before drawing investment conclusions.
