There can be no assurance that New Elroy Air will use the proceeds of the Business Combination and the associated PIPE investment as currently planned, and management will have broad discretion over the use of such proceeds. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of IPAC and Elroy Air.
