About Yellowstone Acquisition Company

Yellowstone Acquisition Company is a blank check company sponsored by Boston Omaha Corporation (NASDAQ: BOMN) and formed for the purpose of effecting a merger, share exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. On August 1, 2021, Yellowstone entered into a business combination agreement with Sky Harbour LLC (“Sky”), a developer of private aviation infrastructure focused on building, leasing and managing business aviation hangars. On December 22, 2021, Yellowstone announced that Boston Omaha Corporation, through its subsidiary BOC YAC, LLC, has agreed to provide $45 million of PIPE financing in connection with the closing of the potential business combination with Sky. The PIPE Financing will be provided through the purchase of Yellowstone Class A common stock at a price of $10.00 per share immediately prior to the closing of the business combination. In consideration of the additional investment, Sky has agreed to waive the $150 million minimum financing condition which required that the Company deliver cash proceeds of at least $150 million (after payment of certain expenses) to Sky as a condition precedent to consummating the business combination. Upon closing of the business combination, Sky will become a publicly traded company, and it is expected that its common stock will be listed on the NYSE.
