These forward-looking statements include, without limitation, Allego’s expectations with respect to future performance. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially, and potentially adversely, from those expressed or implied in the forward-looking statements. Most of these factors are outside Allego’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (i) changes adversely affecting Allego’s business, (ii) the risks associated with vulnerability to industry downturns and regional or national downturns, (iii) fluctuations in Allego’s revenue and operating results, (iv) unfavorable conditions or further disruptions in the capital and credit markets, (v) Allego’s ability to generate cash, service indebtedness and incur additional indebtedness, (vi) competition from existing and new competitors, (vii) the growth of the electric vehicle market, (viii) Allego’s ability to integrate any businesses it may acquire, (ix) Allego’s ability to recruit and retain experienced personnel, (x) risks related to legal proceedings or claims, including liability claims, (xi) Allego’s dependence on third-party contractors to provide various services, (xii) Allego’s ability to obtain additional capital on commercially reasonable terms, (xiii)the impact of COVID-19, including COVID-19 related supply chain disruptions and expense increases, (xiv) general economic or political conditions, including the armed conflict in Ukraine and (xv) other factors detailed under the section entitled “Item 3.D. Risk Factors” of Allego’s Annual Report on Form 20-F for the year ended December 31,2021 and in Allego’s other filings with the U.S. Securities and Exchange Commission (“SEC.”) The foregoing list of factors is not exclusive. If any of these risks materialize or Allego’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that Allego presently does not know or that Allego currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Allego’s expectations, plans or forecasts of future events and views as of the date of this presentation. Allego anticipates that subsequent events and developments will cause Allego’s assessments to change. However, while Allego may elect to update these forward-looking statements at some point in the future, Allego specifically disclaims any obligation to do so, unless required by applicable law. These forward looking statements should not be relied upon as representing Allego’s assessments as of any date subsequent to the date of this presentation. Accordingly, undue reliance should not be placed upon the forward-looking statements. INDUSTRY AND MARKET DATA Although all information and opinions expressed in this presentation, including market data and other statistical information, were obtained from sources believed to be reliable and are included in good faith, Allego has not independently verified the information and makes no representation or warranty, express or implied, as to its accuracy or completeness. Some data is also based on the good faith estimates of Allego, which is derived from its review of internal sources as well as the independent sources described above. This presentation contains preliminary information only, is subject to change at any time and, is not, and should not be assumed to be, complete or to constitute all the information necessary to adequately make an informed decision regarding your engagement with Allego. FINANCIAL INFORMATION; NON-IFRS FINANCIAL MEASURES; CURRENCY CONVERSION Some of the financial information and data contained in this presentation, such as EBITDA, Operational EBITDA and free cash flow, have not been prepared in accordance with Dutch generally accepted accounting principles, United States generally accepted accounting principles or the International Financial Reporting Standards (“IFRS”). We define (i) EBITDA as earnings before interest expense, taxes, depreciation and amortization, (ii) Operational EBITDA as EBITDA further adjusted for reorganization costs, certain business optimization costs, lease buyouts, and transaction costs and (iii) free cash flow as net cash flow from operating activities less capital expenditures. Allego believes that the use of these non-IFRS measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Allego’s financial condition and results of operations. Allego’s management uses these non-IFRS measures for trend analyses, for purposes of determining management incentive compensation and for budgeting and planning purposes. Allego believes that the use of these non-IFRS financial measures provides an additional tool for investors to use in evaluating projected operating results and trends and in comparing Allego’s financial measures with other similar companies, many of which present similar non-IFRS financial measures to investors. Management does not consider these non-IFRS measures in isolation or as an alternative to financial measures determined in accordance with IFRS. The principal limitation of these non-IFRS financial measures is that they exclude significant expenses and income that are required by IFRS to be recorded in Allego’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-IFRS financial measures. In order to compensate for these limitations, management presents non-IFRS financial measures in connection with IFRS results and reconciliations to the most directly comparable IFRS measure are provided in the Appendix to this presentation . TRADEMARKS AND TRADE NAMES Allego owns or has rights to various trademarks, service marks and trade names that it uses in connection with the operation of its businesses. This presentation also contains trademarks, service marks and trade names of third parties, which are the property of their respective owners. The use or display of third parties’ trademarks, service marks, trade names or products in this presentation is not intended to, and does not imply, a relationship with Allego or an endorsement or sponsorship by or of Allego. Solely for convenience, the trademarks, service marks and trade names referred to in this presentation may appear with the ®, TM or SM symbols, but such references are not intended to indicate, in any way, that Allego will not assert, to the fullest extent under applicable law, its rights or the right of the applicable licensor to these trademarks, service marks and trade names. CERTAIN RISKS RELATED TO ALLEGO All references to the “Company,” “Allego,” “we,” “us,” or “our” in this presentation refer to the business of Allego. The risks presented below are certain of the general risks related to Company’s business, industry and ownership structure and are not exhaustive. The list below is qualified in its entirety by disclosures contained in Allego’s Annual Report on Form 20-F for the year ended December 31,2021, as filed with the SEC. These risks speak only as of the date of the presentation, and we have no obligation to update the disclosures contained herein. The risks highlighted in future filings with the SEC may differ significantly from and will be more extensive than those presented below. •    Allego is an early stage company with a history of operating losses, and expects to incur significant expenses and continuing losses for the near term and medium term. • Allego has experienced rapid growth and expects to invest substantially in growth for the foreseeable future. If it fails to manage growth effectively, its business, operating results and financial condition could be adverselyaffected. •Allego’s forecasts and projections are based upon assumptions, analyses and internal estimates developed by Allego’s management. If these assumptions, analyses or estimates prove to be incorrect or inaccurate, Allego’sactual operating results may differ adversely and materially from those forecasted or projected. •Allego’s estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and Allego’s growth and success is highly correlated with and dependent upon the continuing rapid adoption of • •Allego currently faces competition from a number of companies and expects to face significant competition in the future as the market for EV charging develops. •Allego may need to raise additional funds or debt and these funds may not be available when needed. •If Allego fails to offer high-quality support to its customers and fails to maintain the availability of its charging points, its business and reputation may suffer. • Allego relies on a limited number of suppliers and manufacturers for its hardware and equipment and charging stations. A loss of any of these partners or issues in their manufacturing and supply processes could negatively affect its business. •Allego’s business is subject to risks associated with the price of electricity, which may hamper its profitability and growth. •Allego is dependent on the availability of electricity at its current and future charging sites. Delays and/or other restrictions on the availability of electricity would adversely affect Allego’s business and results of operations. •Allego’s EV driver base will depend upon the effective operation of Allego’s EVCloud™ platform and its applications with mobile service providers, firmware from hardware manufacturers, mobile operating systems,networks and standards that Allego does not control. •If Allego is unable to attract and retain key employees and hire qualified management, technical, engineering and sales personnel, its ability to compete and successfully grow its business would be harmed. •Allego is expanding operations in many countries in Europe, which will expose it to additional tax, compliance, market, local rules and other risks. •Members of Allego’s management have limited experience in operating a public company. •New alternative fuel technologies may negatively impact the growth of the EV market and thus the demand for Allego’s charging stations and services. •The European EV market currently benefits from the availability of rebates, scrappage schemes, tax credits and other financial incentives from governments to offset and incentivize the purchase of EVs. The reduction, modification, or elimination of such benefits could cause reduced demand for EVs and EV charging, which would adversely affect Allego’s financial results. •Allego’s business may be adversely affected if it is unable to protect its technology and intellectual property from unauthorized use by third parties. •Allego’s technology could have undetected defects, errors or bugs in hardware or software which could reduce market adoption, damage its reputation with current or prospective customers, and/or expose it to product liability and other claims that couldmaterially andadversely affect its business. •The exclusive forum clause set forth in Allego’s Warrant Agreement may have the effect of limiting an investor’s rights to bring legal action against Allego and could limit the investor’s ability to obtain a favorable judicial forum for disputes with us. •Future sales, or the perception of future sales, of Allego’s ordinary shares and warrants by Allego or selling securityholders, including Madeleine Charging B.V. (“Madeleine”), which is indirectly beneficially owned by Meridiam SAS, could cause the market price for Allego’s ordinary shares andwarrantsto decline significantly. •Madeleine owns a significant amount of Allego’s voting shares and its interests may conflict with those of other shareholders.
