Context This report reflects an institutional 10% owner selling stock (not an executive or officer). Institutional sales can be for many reasons (portfolio rebalancing, liquidity, etc.); the filing itself does not state a motive. The presence of substantial remaining holdings and warrants means Boston Omaha retains significant exposure to Sky Harbour despite this disposition.
