These forward - looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied o n by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events an d circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of the Company. These forward - looking statements are subject to a n umber of risks and uncertainties, including changes in domestic and foreign business, market, financial, political and legal conditions, projections of market opportunity and market share, potential benefits and commercial attractiveness to its custo mer s of the Company’s services, the potential success of the Company’s marketing and expansion strategies, the Company’s ability to scale and the timing of expected business milestones, the inability of the parties to successfully or timely consummate the p rop osed business combination, including the risk that any required regulatory approvals are not obtained, are delayed or are sub jec t to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business c omb ination or that the approval of the stockholders of the Company or Athena is not obtained, failure to realize the potential b ene fits of the business combination (including with respect to stockholder value), the effects of competition on the Company’s future bu sin ess, the amount of redemption requests made by Athena’s public stockholders, the ability of Athena or the combined company to issue equity or equity - linked securities in connection with the proposed business combination or in the future, and expectations related to the terms and timing of the potential transactions and those factors discussed in Athena’s final prospectus filed on February 5, 2021, under the heading “Risk Factors,” and other documents of Athena filed, or to be filed, including the proxy statement /pr ospectus expected to be filed in connection with the business combination, with the Securities and Exchange Commission (“SEC” ). If any of these risks materialize or if assumptions prove incorrect, actual results could differ materially from the results imp lie d by these forward - looking statements. There may be additional risks that are not presently known to the Company or that the Com pany currently believes are immaterial that could also cause actual results to differ from those contained in the forward - looking sta tements. In addition, forward - looking statements reflect the Company’s expectations, plans or forecasts of future events and vie ws as of the date of the Pack. The Company anticipates that subsequent events and developments will cause the Company’s assessments to ch ange. However, while the Company may elect to update these forward - looking statements at some point in the future, the Company specifically disclaims any obligation to do so. These forward - looking statements should not be relied upon as representi ng the Company’s assessments as of any date subsequent to the date of the Pack. Accordingly, undue reliance should not be placed upon the forward - looking statements. Use of Projections and Description of Key Relationships The Pack contains projected financial information with respect to the Company, namely revenue and the non - GAAP financial measures, E BITDA and Free Cash Flow for 2021 – 2026. Such projected financial information constitutes forward - looking information, and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The as sum ptions and estimates underlying such projected financial information are inherently uncertain and are subject to a wide varie ty of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ mater ial ly from those contained in the prospective financial information See “Forward - Looking Statements” above. Actual results may differ materially from the results contemplated by the projected fina ncial information contained in the Pack, and the inclusion of such information in the Pack should not be regarded as a repres ent ation by any person that the results reflected in such projections will be achieved. The independent registered public accounting f irm of the Company has not audited, reviewed, compiled, or performed any procedures with respect to the projections for the purpo se of their inclusion in the Pack, and accordingly, does not express an opinion or provided any other form of assurance with respec t t hereto for the purpose of the Pack .

 

 

Disclaimer 2 The Pack contains descriptions of certain key business relationships of the Company. These descriptions are based on the Comp any ’s management team’s discussions with such counterparties and the latest available information and estimates as of the date o f the Pack. In certain cases, such descriptions are subject to negotiation and execution of definitive agreements with such cou nte rparties which have not been completed as of the date of the Pack and, as a result, such descriptions of key business relatio nsh ips of the Company, remain subject to change Financial Information; Non - GAAP Financial Measures The financial information and data contained in the Pack is unaudited and does not conform to Regulation S - X. Some of the financ ial information and data contained in the Pack, such as EBITDA and Free Cash Flow, have not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). EBITDA is defined as net earnings (loss) before interest exp ens e, income tax expense (benefit) depreciation and amortization Free cash flow is defined as net income, plus depreciation and amortization, less capital expenditures (incl. acquisitions) and less change in net working capital. The Company believes the se non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations. The Company believes that the use of th ese non - GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and t rends in and in comparing the Company’s financial measures with other similar companies, many of which present similar non - GAAP financ ial measures to investors. Management does not consider these non - GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non - GAAP financial measures is that the y exclude significant expenses and income that are required by GAAP to be recorded in the Company’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expens e a nd income are excluded or included in determining these non - GAAP financial measures. In order to compensate for these limitation s, management presents non - GAAP financial measures in connection with GAAP results. Please refer to the Appendix for a reconciliati on of the Company’s projected EBITDA and free cash flow for full years 2021 - 2026 to the most directly comparable measure prepared in accordance with GAAP because the Company is unable to provide this reconciliation without unreasonable effort due to the uncertainty and inherent difficulty of predicting the occurrence, the financial impact, and the periods in which the adju st ments may be recognized.. In addition, all the Company historical financial information included herein is preliminary and subject to change pending fi nal ization of the 2020 audit of the Company in accordance with PCAOB auditing standards. Trademarks The Pack contains trademarks, service marks, trade names and copyrights of the Company and other companies, which are the pro per ty of their respective owners.
