In some cases, forward - looking statements can be identified by words such as “anticipate,” “approximate,” “believe,” “plan,” “estimate,” “expect,” “project,” “could,” “should,” “strategy,” “will,” “intend,” “may” and other similar expressions or the negative of such words or expressions. Statements in this presentation concerning (i) Athena’s or Ace Green’s expected future financial position, business strategy, production capacity, competitive positions, growth opportunities, plans and objectives of management and (ii) the expected benefits of the Business Combination, together with other statements that are not historical facts, are forward - looking statements that are estimates reflecting management’s best judgment based upon currently available information. Such forward - looking statements are inherently uncertain, and stockholders and other potential investors must recognize that actual results may differ materially from expectations as a result of a variety of factors, including, without limitation, those discussed below. Such forward - looking statements are based upon management’s current expectations and include known and unknown risks, uncertainties and other factors, many of which Athena and Ace Green are unable to predict or control, that may cause actual results, performance or plans to differ materially from any future results, performance or plans expressed or implied by such forward - looking statements. These statements involve risks and uncertainties that could cause actual results to differ materially from those anticipated in these statements as a result of a number of factors, including, but not limited to: • Ace Green has a limited operating history at scale and is developing a flagship and new facility in the United States; scaling up its operations and expansion in the U.S. may carry uncertainties and pose liquidity risks to Ace Green; • Ace Green may not be able to secure adequate capital to execute its business plan; • If Ace Green is unable to overcome the workforce and engineering challenges arising from scaling up production from its existing capacities, it may not succeed in executing its growth and expansion plans; • Successful or timely implementation of Ace Green’s planned U.S. facility may be delayed due to licensing or regulatory issues; • A large portion of Ace Green’s profit is derived from a relatively small number of major customers, and its business, financial condition, and results of operations could be materially and adversely affected if its key customers fail to meet their contractual obligations; • Prices for recovered materials are subject to global market fluctuations and price instability may negatively impact Ace Green’s financial performance; • Ace Green relies on third - party vendors for key machineries and failure to acquire and maintain them may adversely disrupt its operations; • A decline in green energy adoption may inhibit future recycling opportunities and may result in decreased demand for Ace Green’s products; • Ace Green’s proprietary know - how may be rivaled by competitors, which may erode the technological edge it has established; • Unfavorable economic or geopolitical conditions could constrain Ace Green’s expansion, inhibit its further growth and otherwise have a material adverse effect its business, results of operations, prospects and financial condition; • Athena and Ace Green may not obtain the requisite stockholder approvals for the Business Combination; • Nasdaq may not list the common stock of the surviving company following the Business Combination, which could limit investors’ ability to effect transactions following the Business Combination; • An event, change or other circumstance could result in the termination of the Business Combination; • A condition to the closing of the Business Combination may not be satisfied; • There may be delays in completing the Business Combination; • Any announcement or news coverage relating to the Business Combination could have adverse effects on the market price of Athena common stock or Ace Green common stock; • The risk of litigation related to the merger; and • Other risks and uncertainties identified in the “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business” sections of Athena’s most recent Annual Report on Form 10 - K and its subsequent Quarterly Reports on Form 10 - Q, and other risks as identified from time to time in its Securities and Exchange Commission (“SEC”) reports.
