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 Atlas Crest and Archer. These statements are subject to a number of risks and uncertainties regarding the businesses of Atlas Crest and Archer and the business combination, and actual results may differ materially. These risks and uncertainties include, but are not limited to, the early stage nature of Archer’s business and its past and projected future losses; Archer’s ability to manufacture and deliver aircraft and its impact on the risk of investment; Archer’s dependence on United Airlines for its current aircraft orders and development process, and the risk that United Airlines cancels its contracts with Archer; risks relating to the uncertainty of the projections included in the model; the effectiveness of Archer’s marketing and growth strategies, including its ability to effectively market air transportation as a substitute for conventional methods of transportation; Archer’s ability to compete in the competitive urban air mobility and eVTOL industries; Archer’s ability to obtain expected or required certifications, licenses, approvals, and authorizations from transportation authorities; Archer’s ability to achieve its business milestones and launch products on anticipated timelines; Archer’s dependence on suppliers and service partners for the parts and components in its aircraft; Archer’s ability to develop commercial-scale manufacturing capabilities; regulatory requirements and other obstacles outside of Archer’s control that slow market adoption of electric aircraft, such as Archer’s inability to obtain and maintain adequate facilities and Vertiport infrastructure; Archer’s ability to hire, train and retain qualified personnel; risks related to Archer’s Aerial Ride Sharing Business operating in densely populated metropolitan areas and heavily regulated airports; adverse publicity from accidents involving aircraft, helicopters or lithium-ion battery cells; the impact of labor and union activities on Archer’s workforce; losses resulting from indexed price escalation clauses in purchase orders and cost overruns; regulatory risks related to evolving laws and regulations in Archer’s industries; impact of the COVID-19 pandemic on Archer’s business and the global economy; the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the stockholders of Atlas Crest or Archer is not obtained; a decline in Archer’s securities following the business combination if it fails to meet the expectations of investors or securities analysts; Archer’s inability to protect its intellectual property rights from unauthorized use by third parties; Archer’s need for and the availability of additional capital; cybersecurity risks; risks and costs associated with the ongoing litigation with Wisk Aero LLC; the dual class structure of Archer’s common stock, which will limit other investors’ ability to influence corporate matters; the amount of redemption requests made by Atlas Crest’s public stockholders; the ability of Atlas Crest or the combined company to issue equity or equity-linked securities in connection with the proposed business combination or in the future, and those factors discussed in Atlas Crest’s definitive proxy statement/prospectus, dated August 11, 2021 under the heading “Risk Factors,” filed with the SEC on August 11, 2021. If any of these risks materialize or if assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements.
