Forward - looking statements may include, but are not limited to, statements regarding GX’s or Celularity’s expectations, hopes, beliefs, intentions or strategies regarding the future, including, without limitation, statements regarding: (i) the success and timing of Celularity’s cellular therapeutic development activities and initiating clinical trials, (ii) the success and timing of Celularity’s planned clinical trials, (iii) Celularity’s ability to obtain and maintain regulatory approval of any of Celularity’s therapeutic candidates, (iv) Celularity’s plans to research, discover and develop additional therapeutic candidates, including by leveraging genetic engineering and other technologies and expanding into additional indications, (v) Celularity’s ability to expand its manufacturing capabilities, and to manufacture Celularity’s therapeutic candidates and scale production, and (vi) Celularity’s ability to meet the milestones set forth herein. Any statements contained herein, including any underlying assumptions, that are not statements of historical fact may be deemed to be forward - looking statements and any such projections, statements, forecasts and other information or characterizations of future events or circumstances reflect various estimates and assumptions concerning anticipated results. Forward - looking statements include statements regarding Celularity’s future financial position and performance, business strategy, budgets, projected costs, plans, synergies and objectives of management for future operations. Without limiting the foregoing, the words “believes,” “anticipates,” “continues”, “could”, “may”, “might”, “plans,” “expects,” “intends,” “estimated,” “forecasted,” “projection”, “possible”, “potential”, “predicted”, “projected”, “should”, “strive”, “would” and similar expressions used in connection with any discussion of future operating or performance may identify forward - looking statements, but the absence of these words does not necessarily mean that a statement is not forward - looking. Forward - looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. You should carefully consider the risks and uncertainties described in the “Risk Factors” section of the registration statement on Form S - 4 (the “ S - 4 Registration Statement ”), which was initially filed with the SEC on January 25, 2021 and amended on March 29, 2021 and April 23, 2021, including the preliminary proxy statement/prospectus contained therein, GX’s registration statement on Form S - 1 and other documents filed by GX from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward - looking statements. Forward - looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward - looking statements. No representations or warranties are made by GX, Celularity or any of their respective affiliates or representatives as to the accuracy of any such projections, modeling, data, targets, statements and other information contained herein. It is understood and agreed that any such projections, models, data, targets, statements and other information are not to be viewed as facts and are subject to significant business, financial, economic, operating, competitive and other risks, uncertainties and contingencies many of which are beyond GX and Celularity’s control, that no assurance can be given that any particular financial projections, ranges, or targets will be realized, that actual results may differ from projected results and that such differences may be material. These forward - looking statements are based on Celularity management’s current expectations and beliefs about future events based on information available to them as of the date hereof. As with any projection or forecast, they are inherently susceptible to uncertainty and changes in circumstances. Except as required by law, neither GX nor Celularity is under any obligation to, and expressly disclaims any obligation to, update or alter any forward - looking statements whether as a result of any such changes, new information, subsequent events or otherwise. Achieving GX’s and Celularity’s business and financial objectives, including growth in operations and maintenance of a strong balance sheet and liquidity position, could be adversely affected by, among other things: (i) the risk that the Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of GX's securities; (ii) the risk that the Business Combination may not be completed by GX's business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by GX; (iii) the failure to satisfy the conditions to the consummation of the Business Combination, including the adoption of the Merger Agreement (as defined below) by the stockholders of GX; (iv) the satisfaction of the minimum trust account amount following redemptions by GX's public stockholders and the receipt of certain governmental and regulatory approvals; (v) the lack of a third party valuation in determining whether or not to pursue the Business Combination; (vi) the occurrence of any event change or other circumstance that could give rise to the termination of the Merger Agreement, (vi) the outcome of any legal proceedings that may be instituted against Celularity or against GX related to the Business Combination; (ix) the ability to maintain the listing of the GX's securities on Nasdaq; (x) risks inherent in developing Celularity's therapeutic candidates; (xi) risks associated with Celularity's ongoing and planned clinical trials, such as unexpected data or clinical site activation rates or clinical trial enrollment rates that are lower than expected; (xii) difficulties arising from Celularity's third - party licenses, or supply - chain or manufacturing challenges; (xiii) Celularity's ability to obtain adequate financing to fund its planned clinical trials and other expenses; and (xiv) trends in the industry, changes in the competitive landscape, delays or disruptions due to the COVID - 19 pandemic, as well as changes in the legal and regulatory framework for the industry or unexpected litigation or disputes and future expenditures. Other unknown or unpredictable factors or factors currently considered immaterial also could have an adverse effect on GX’s or Celularity’s results. Consequently, there can be no assurance that the actual results or developments anticipated by GX or Celularity will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, GX or Celularity.
