Allego N.V. ("Allego") intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. Forward-looking statements may generally be identified by the use of words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "plan,", "project," "forecast," "predict," "potential," "seem," "seek," "future," "outlook," "target" or other similar expressions (or the negative versions of such words or expressions) that predict or indicate future events or trends or that are not statements of historical matters. 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 price and availability of electricity and other energy sources, (iii) the risks associated with vulnerability to industry downturns and regional or national downturns, (iv) fluctuations in Allego's revenue and operating results, (v) unfavorable conditions or further disruptions in the capital and credit markets, (vi) Allego's ability to generate cash, service indebtedness and incur additional indebtedness, (vii) competition from existing and new competitors, (viii) the growth of the electric vehicle market, (ix) Allego's ability to integrate any businesses it may acquire, (x) Allego's ability to recruit and retain experienced personnel, (xi) risks related to legal proceedings or claims, including liability claims, (xii) Allego's dependence on third-party contractors to provide various services, (xiii) data security breaches or other network outage; (xiv) Allego's ability to obtain additional capital on commercially reasonable terms, (xv) Allego's ability to remediate its material weaknesses in internal control over financial reporting, (xvi) the impact of COVID-19, including COVID-19 related supply chain disruptions and expense increases, (xvii) general economic or political conditions, including the Russia/Ukraine conflict or increased trade restrictions between the United States, Russia, China and other countries; and (xviii) other factors detailed under the section entitled "Risk Factors" in Allego's filings with the Securities and Exchange Commission. 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 investment with Allego. FINANCIAL INFORMATION; NON-IFRS FINANCIAL MEASURES 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") as issued by the International Accounting Standards Board. 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.

Following the adoption of the alternative fuel infrastructure regulation (AFIR), from 2025 onward, fast charging stations of at least 150kW must be installed every 60 km along the EU's main transport corridors. European regulations continue to tighten, with 8 countries banning internal combustion engine (ICE) vehicles sales by 2030 and the EU banning ICE vehicles sales by 2035 supporting solid growth fundamentals Source.
