PRELIMINARY PROSPECTUS

Allego N.V.

13,799,948 ORDINARY SHARES

Offered by Allego N.V.

66,493,170 ORDINARY SHARES

Offered by Selling Securityholders

This prospectus relates to the issuance by us of up to 13,799,948 ordinary shares, with a nominal value of € 0.12 per share (“Ordinary Shares”) of Allego N.V., a public limited liability company (naamloze vennotschap) governed by the laws of the Netherlands (“Allego”), that are issuable upon the exercise of 13,799,948 Warrants to purchase Ordinary Shares, which were originally Public Warrants (as defined below) issued in the initial public offering of units of Spartan Acquisition Corp. III (“Spartan”) at a price of $10.00 per unit, with each unit consisting of one share of Class A common stock and one-fourth of one Public Warrant. See “Prospectus Summary—Recent Developments—Business Combination.”

This prospectus also relates to the offer and sale from time to time by the selling securityholders named in this prospectus (the “Selling Securityholders”), or their permitted transferees, of up to 66,493,170 Ordinary Shares (the “Total Resale Shares”), which includes (i) 13,700,000 Ordinary Shares that were issued in exchange for Spartan Founders Stock, originally purchased at a price of approximately $0.002 per share, upon the closing of the Business Combination (the “Business Combination”), (ii) 10,360,227 Ordinary Shares issued to a limited number of qualified institutional buyers and institutional and individual accredited investors (the “Private Placement Investors”) at a price of $10.00 per Ordinary Share on the closing of the Business Combination, (iii) 41,097,994 Ordinary Shares that were issued in exchange for Allego Holding Shares (as defined below) to the E8 Investor (as defined below) as compensation under the Special Fees Agreement (as defined below), based on a value of Allego and its subsidiaries of $10.00 per share, upon the closing of the Business Combination and (iv) 1,334,949 Ordinary Shares that were issued to AP Spartan Energy Holdings III (PPW), LLC (“AP PPW”) at a price of $11.50 per share on a cashless exercise basis upon its exercise of 9,360,000 Warrants to purchase Ordinary Shares, which were originally Private Placement Warrants purchased at a price of $1.50 per Private Placement Warrant that were automatically converted into Warrants upon the closing of the Business Combination. See “Prospectus Summary—Recent Developments—Business Combination.”

Each Warrant entitles the holder thereof to purchase one Ordinary Share at a price of $11.50 per share. We will receive proceeds from the exercise of the Warrants to the extent the Warrants are exercised for cash, which amount of aggregate proceeds, assuming the exercise of all Warrants, could be up to $158,699,402. We believe the likelihood that Warrant holders will exercise their Warrants, and therefore the amount of cash proceeds that we would receive, is dependent upon the market price of our Ordinary Shares. If the market price for our Ordinary Shares is less than $11.50 per share, we believe the Warrant holders will be less likely to exercise their Warrants. We will not receive any proceeds from the sale of Ordinary Shares by the Selling Securityholders pursuant to this prospectus. However, we will pay the expenses, other than underwriting discounts and commissions and expenses incurred by the Selling Securityholders for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Securityholders in disposing of the securities, associated with the sale of Ordinary Shares pursuant to this prospectus.

Our registration of the Ordinary Shares covered by this prospectus does not mean that either we or the Selling Securityholders will offer or sell, as applicable, any of the Ordinary Shares. The Selling Securityholders may offer and sell the Ordinary Shares covered by this prospectus in a number of different ways and at varying prices. We provide more information about how the Selling Securityholders may sell the Ordinary Shares in the section entitled “Plan of Distribution.”

Madeleine Charging B.V., a Dutch private limited liability company (“Madeleine”), our majority shareholder, owns approximately 74.1% of our Ordinary Shares and has the right to direct the voting of an additional approximately 15.4% of our outstanding Ordinary Shares, pursuant to an irrevocable voting power of attorney granted by another investor in our company. As a result, Madeleine controls matters requiring shareholder or board approval, including the election of directors. Accordingly, we are a “controlled company” under New York Stock Exchange (“NYSE”) corporate governance rules and are eligible for certain exemptions from these rules. We are a “foreign private issuer” under applicable Securities and Exchange Commission rules and an “emerging growth company” as that term is defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) and are eligible for reduced public company disclosure requirements.

Our Ordinary Shares and Warrants are listed on the NYSE under the symbols “ALLG” and “ALLG.WS,” respectively. On September 29 2022, the last reported sale price of our Ordinary Shares was $4.52 per share and the last reported sale price of our Warrants was $4.52.

Prior to the extraordinary meeting of Spartan in connection with the Business Combination, holders of 54,092,418 shares of Spartan Class A Common Stock exercised their right to redeem those shares for cash at a price of approximately $10.00 per share, for an aggregate of $540,984,673, which represented approximately 97.99% of the total Spartan Common Stock then outstanding. The Total Resale Shares being offered for resale in this prospectus represent approximately 24.9% of our current total outstanding Ordinary Shares. The Total Resale Shares represent a substantial percentage of our total outstanding Ordinary Shares as of the date of this prospectus. The sale of all securities being offered in this prospectus could result in a significant decline in the public trading price of our Ordinary Shares. Despite such a decline in the public trading price, the Selling Securityholders may still experience a positive rate of return on the securities they purchased due to the difference in the purchase prices described above. Based on the closing price of our Ordinary Shares referenced above, (a) the holders of Ordinary Shares that were issued in exchange for Spartan Founders Stock may experience potential profit of up to $4.52 per Ordinary Share. The Private Placement Investors and the E8 Investor will only experience a profit if the sale price of the Ordinary Shares exceeds $10.00 per share and AP PPW will only experience a profit if the sale price of the Ordinary Shares exceeds $13.00 per share. Even though the current trading price of the Ordinary Shares is close to the price at which the units were issued in Spartan’s initial public offering, the Selling Securityholders may have an incentive to sell because they may still experience a positive rate of return based on the current trading price. The public securityholders may not experience a similar rate of return on the securities they purchase due to differences in the purchase prices and the current trading price.

FINANCIAL STATEMENT PRESENTATION

Accounting Treatment of the Business Combination

Athena Pubco B.V. was incorporated by Madeleine on June 3, 2021 for the purpose of effectuating the Business Combination described herein. See “Prospectus Summary – Recent Developments – Business Combination.” Prior to the Business Combination, Athena Pubco B.V., which was redesignated as Allego N.V. in connection with the Closing, had no material assets and did not operate any businesses. The Business Combination resulted in Allego acquiring Allego Holding and combining with Spartan, with an exchange of the shares and warrants issued by Spartan for those of Allego. The Business Combination was accounted for as a capital reorganization followed by the combination with Spartan, which was treated as a recapitalization. Following the Business Combination, both Allego Holding and Spartan are wholly owned subsidiaries of Allego.

Basis of Pro Forma Presentation

The adjustments presented on the pro forma combined financial statements have been identified and presented to provide an understanding of Allego upon consummation of the Business Combination for illustrative purposes only. The financial results may have been different had the companies always been combined for the historical periods presented here. You should not rely on the pro forma combined financial statements as being indicative of the future financial position and results that Allego will experience.

RISK FACTORS

An investment in Allego’s securities carries a significant degree of risk. You should carefully consider the following risks and other information in this prospectus, including our consolidated financial statements and related notes included elsewhere in this prospectus, before you decide to purchase Allego’s securities. Additional risks and uncertainties of which we are not presently aware or that we currently deem immaterial could also affect our business operations and financial condition. If any of these risks actually occur, our business, financial condition, results of operations or prospects could be materially affected. As a result, the trading price of Allego’s securities could decline and you could lose part or all of your investment.

Risks Relating to Allego’s Business, Industry and Regulatory Environment

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 incurred an operating loss of € 262.1 million for the quarter ended June 30, 2022 and as of June 30, 2022, Allego had a total equity of approximately € 97.6 million. Allego believes it will continue to incur net losses in each quarter for the near term. Even if it achieves profitability, there can be no assurance that it will be able maintain profitability in the future. Allego’s potential profitability is particularly dependent upon the continued adoption of EVs by consumers in Europe, which may occur at a slower pace than anticipated or may not occur at all. This continued adoption may depend upon continued support from regulatory programs and in each case, the use of Allego chargers and Allego services may be at much lower levels than Allego currently anticipates.

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 adversely affected.

Allego has experienced rapid growth in recent periods that has placed and continues to place a significant strain on employee retention, management, operations, financial infrastructure and corporate culture and has required several strategic adjustments. Allego’s revenue has increased from € 44.2 million in 2020 to € 86.3 million in 2021. In addition, in the event of further growth, Allego’s information technology systems and Allego’s internal control over financial reporting and procedures may not be adequate to support its operations and may increase the risk of data security incidents that may interrupt business operations and permit bad actors to obtain unauthorized access to business information or misappropriate company funds. Allego may also face risks to the extent such bad actors infiltrate the information technology infrastructure of its contractors. Allego may also face the risk that EVCloud^TM, its core platform, is not able to support Allego’s growth due to increased traffic on Allego charging points, which would interrupt business operations. Allego could then also face contractual penalties with its customers if this results in a failure to meet its contractual obligations.

To manage growth in operations and personnel management, Allego will need to continue to improve its operational, financial and management controls and reporting systems and procedures. Failure to manage growth effectively could result in difficulty or delays in developing new EV charging sites, in attracting new customers, declines in quality or customer satisfaction, increases in costs, difficulties in introducing new solutions and services or enhancing existing solutions and services, loss of EV sites and customers, information security vulnerabilities or other operational difficulties, any of which could adversely affect its business performance and operating results.

Allego’s estimates of market opportunity and forecasts of market growth may prove to be inaccurate.

Market opportunity estimates and growth forecasts, whether obtained from third-party sources or developed internally, are subject to significant uncertainty and are based on assumptions and estimates that may prove to be

14

inaccurate. This is especially so at the present time due to the uncertain and rapidly changing projections of the severity, magnitude and duration of the COVID-19 pandemic. Estimates and forecasts relating to the size and expected growth of the target market, market demand, EV adoption across each individual national market in Europe and use cases, capacity of automotive and battery OEMs and ability of charging infrastructure to address this demand and related pricing may also prove to be inaccurate. In particular, estimates regarding the current and projected market opportunity for public fast and ultrafast charging or Allego market share capture are difficult to predict. The estimated addressable market may not materialize in the timeframe of the projections, if ever, and even if the markets meet the size estimates and growth estimates, Allego’s business could fail to grow at similar rates.

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.

The EV charging market is relatively new, and competition is still developing. Apart from China, Europe is the biggest EV market in the world and is more mature than the United States. Allego competes in its charging network and services businesses with many competitors. With respect to the development of its own public EV charging network, Allego primarily competes with incumbent utilities and oil and gas companies alongside pure EV charging players and companies linked to car manufacturers. With respect to its services business, Allego competes with a variety of companies, including hardware manufacturers, software platform vendors, installation companies and maintenance contractors. Despite Allego’s longstanding European presence, it must continuously strive to remain competitive in its markets. Competition may hamper global EV adoption as an influx of providers may lead to poor service and trust in any one provider of EV charging solutions.

In addition, there are means for charging EVs other than publicly accessible charging, which could affect the level of demand for onsite charging capabilities at public or commercial areas, which are Allego’s primary focus. For example, Tesla Inc. continues to build out its supercharger network across Europe for its vehicles, which could reduce overall demand for EV charging at other sites. Tesla may also open its supercharger network to support charging of non-Tesla EVs in the future, which could further reduce demand for charging at Allego’s sites. Additionally, third- party contractors can provide basic electric charging capabilities to potential customers of Allego, including commercial on premise charging and home charging solutions. Many EV hardware manufacturers are now offering home charging equipment, which could reduce demand for public charging if EV owners find charging at home to be more convenient. Regulations imposing home or workplace charging capabilities for all new buildings could also adversely affect the development of public charging versus home charging.

Furthermore, Allego’s current or potential competitors may be acquired by third-parties with greater available resources. As a result, competitors may be able to respond more quickly and effectively than Allego to new or changing opportunities, technologies, standards or customer requirements and may have the ability to initiate or withstand substantial price competition. In addition, competitors may in the future establish cooperative relationships with vendors of complementary products, technologies or services to increase the availability of their solutions in the marketplace. This competition may also materialize in the form of costly intellectual property disputes or litigation.

New competitors or alliances may emerge in the future that have greater market share, more widely adopted proprietary technologies, greater marketing expertise and greater financial resources, which could put Allego at a competitive disadvantage. Future competitors could also be better positioned to serve certain segments of Allego’s current or future target markets, which could increase costs and create downward pricing pressure on charging sessions. In light of these factors, even if Allego’s public charging network is larger and provides faster charging, and if its services offerings are more effective, higher quality and address more complex demands than those of its competitors, current or potential customers may accept other competitive solutions. If Allego fails to adapt to changing market conditions or continue to compete successfully with current charging providers or new competitors, its growth will be limited, which would adversely affect its business and results of operations.

15

Allego’s future revenue growth will depend in significant part on its ability to increase the number and size of its charging sites and the sales of services to Business to Business (“BtoB”) customers.

Allego’s future revenue growth will depend in significant part on its ability to increase the number and size of its charging sites and its sales of services to BtoB customers. The sites Allego may wish to lease or acquire may first be leased or acquired by competitors or they may no longer be economically attractive due to certain adverse conditions such as increased rent which would hamper the growth and profitability of Allego’s business.

Furthermore, Allego’s BtoB customer base may not increase as quickly as expected because the adoption of EVs may be delayed or transformed by new technologies. In addition to the factors affecting the growth of the EV market generally, transitioning to an EV fleet for some customers or providing EV equipment to facilities for other customers can be costly and capital intensive, which could result in slower than anticipated adoption. The sales cycle for certain BtoB customers could also be longer than expected.

Allego may need to raise additional funds or debt and these funds may not be available when needed.

Allego may need to raise additional capital or debt in the future to further scale its business and expand to additional markets. Allego may raise additional funds through the issuance of equity, equity-related or debt securities, or through obtaining credit from financial institutions. Allego cannot be certain that additional funds will be available on favorable terms when required, or at all. If Allego cannot raise additional funds when needed, its financial condition, results of operations, business and prospects could be materially and adversely affected. If Allego raises funds through the issuance of debt securities or through loan arrangements, the terms of such arrangements could require significant interest payments, contain covenants that restrict Allego’s business, or other unfavorable terms. In addition, to the extent Allego raises funds through the sale of additional equity securities, Allego shareholders would experience additional dilution. For example, in order to meet its current funding needs, Allego borrowed € 50,000,000 under its existing senior debt facility during the third quarter of 2022, which resulted in the amounts under such facility being fully drawn, and will utilize the proceeds from the recently completed Business Combination and Private Placement.

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.

Once Allego charging points are operational, customers rely on Allego to provide maintenance services to resolve any issues that might arise in the future. Rapid and high-quality customer and equipment support is important so that drivers can reliably charge their EVs. The importance of high-quality customer and equipment support will increase as Allego seeks to expand its public charging network and retain customers, while pursuing new EV drivers and geographies. If Allego does not quickly resolve issues and provide effective support, its ability to retain EV drivers or sell additional services to BtoB customers could suffer and its brand and reputation could be harmed.

Allego faces risks related to health pandemics, including the COVID-19 pandemic, which could have a material adverse effect on its business and results of operations.

The impact of COVID-19, including changes in consumer and business behavior, pandemic fears and market downturns, and restrictions on business and individual activities, has created significant volatility in the global economy and has led to reduced economic activity. The spread of COVID-19 has created supply chain disruptions for vehicle manufacturers, suppliers and hardware manufacturers, as well as impacted the capacities of installers. Any sustained downturn in demand for EVs would harm Allego’s business despite its historical growth.

Allego has modified its business practices by recommending that all non-essential personnel work from home and cancelling or shifting physical participation in sales activities, meetings, events and conferences to

16

online engagement. Allego has also implemented additional safety protocols for essential workers, has implemented measures to reduce its operating costs, and may take further actions as may be required by government authorities or that it determines are in the best interests of its employees, customers, suppliers, vendors and business partners in light of COVID-19. There is no certainty that such actions will be sufficient to mitigate the risks posed by the virus or otherwise be satisfactory to government authorities. If significant portions of Allego’s workforce in the future are unable to work effectively, including due to illness, quarantines, social distancing, government actions or other restrictions in connection with the COVID-19 pandemic, its operations will be negatively impacted. Furthermore, if significant portions of its customers’ or potential customers’ workforces are subject to stay-at-home orders or otherwise have substantial numbers of their employees working remotely for sustained periods of time, user demand for EV charging sessions and services may decline.

As of June 30, 2022, the impact of COVID-19 to Allego’s business has been limited, but prospects and results of operations will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the pandemic, its severity, the actions to contain the virus or treat its impact, the efficacy and distribution of COVID-19 vaccines, the outbreak of new COVID-19 variants, and when and to what extent normal economic and operating activities can resume. The COVID-19 pandemic could limit the ability of customers, suppliers, vendors and business partners to perform, including third-party suppliers’ ability to provide components and materials used for Allego’s charging stations or in providing transport, installation or maintenance services. Even after the COVID-19 pandemic has subsided, Allego may continue to experience an adverse impact to its business as a result of COVID-19’s global economic impact, including any economic recession that has occurred or may occur in the future that will have an impact in the growth of EVs and in the growth of EV charging demand.

Specifically, difficult macroeconomic conditions, such as decreases in per capita income and level of disposable income, increased and prolonged unemployment or a decline in consumer confidence as a result of the COVID-19 pandemic, as well as reduced spending by businesses, could each have a material adverse effect on the demand for Allego’s charging points network and services.

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. For example, supply chain challenges related to the COVID-19 pandemic, Russia’s invasion of the Ukraine and global chip shortages have impacted companies worldwide and may have adverse effects on Allego’s suppliers and customers and, as a result, Allego.

Allego has extended its hardware and equipment supplier base but it still relies on a limited number of suppliers, although it is not dependent on any one supplier. This reliance on a limited number of hardware manufacturers increases Allego’s risks, since it does not currently have proven alternatives or replacement manufacturers beyond these key parties. In the event of interruption or insufficient capacity, it may not be able to increase capacity from other sources or develop alternate or secondary sources without incurring material additional costs and substantial delays. In particular, disruptions or shortages at such suppliers, including as a result of delays or issues with their supply chain, including in respect of electronic chips, processors, semiconductors and other electronic components or materials, can negatively impact deliveries by such suppliers to Allego. Thus, Allego’s business could be adversely affected if one or more of its suppliers is impacted by any interruption at a particular location or decides to reduce its deliveries to Allego for any reason including its acquisition by a third-party or is unable to provide Allego with the quantities Allego requires for its growth.

If Allego experiences an increase in demand greater than expected for the development of its charging stations or from its services customers or if it needs to replace an existing supplier, it may not be possible to supplement or replace them on acceptable terms, which may undermine Allego’s ability to capture higher growth or deliver solutions to customers in a timely manner. For example, it may take a significant amount of time to identify a new hardware manufacturer that has the capability and resources to build hardware and equipment in sufficient volume that meets Allego’s specifications. Identifying suitable suppliers and manufacturers could be an

17

extensive process that would require Allego to become satisfied with such suppliers’ and manufacturers’ quality control, technical capabilities, responsiveness and service, financial stability, regulatory compliance, and labor and other ethical practices. Accordingly, a loss of any significant suppliers or manufacturers could have an adverse effect on Allego’s business, financial condition and operating results.

Furthermore, Allego’s hardware and equipment may experience technical issues, including safety issues, which could, on a large scale, negatively impact Allego’s business and potentially in the most extreme cases lead Allego to an early replacement program of such hardware, resulting in Allego incurring substantial additional costs and delays.

In addition, the conflict between Russia and Ukraine could lead to disruption, instability and volatility in global markets and industries that could negatively impact Allego’s supply chain. The U.S. government and other governments have already imposed severe sanctions and export controls against Russia and Russian interests and may yet impose additional sanctions and controls. The impact of these measures, as well as potential responses to them by Russia, is currently unknown and could adversely affect Allego’s supply chain, which, in turn, could affect Allego’s business and operating results.

Allego’s business is subject to risks associated with construction, cost overruns and delays, and other contingencies that may arise in the course of completing installations, and such risks may increase in the future as Allego expands its charging networks and increases its service to third-parties.

Allego does not typically install charging points directly on leased sites or at customer sites. These installations are typically performed by Allego’s electrical contractors at its own sites or with contractors with an existing relationship with the customer and/or knowledge of the site. The installation of charging stations at a particular site is generally subject to oversight and regulation in accordance with national and local laws and regulations relating to building codes, safety, environmental protection and related matters, and typically requires various local approvals and permits, such as grid connection permits that may vary by jurisdiction. In addition, building codes, accessibility requirements or regulations may hinder EV charger installation due to potential increased costs to the developer or installer in order to meet such requirements. Meaningful delays or cost overruns may impact Allego’s recognition of revenue in certain cases and/or impact customer relationships, either of which could impact Allego’s business and profitability.

Contractors may require that Allego or Allego’s customers obtain licenses in order to perform their services. Furthermore, additional rules on working conditions and other labor requirements may result in more complex projects with higher project management costs. If these contractors are unable to provide timely, thorough and quality installation-related services, Allego could fall behind its construction schedules which may cause EV drivers and Allego’s customers to become dissatisfied with Allego’s network and charging solutions. As the demand for public fast and ultrafast charging increases and qualifications for contractors become more stringent, Allego may encounter shortages in the number of qualified contractors available to complete all of Allego’s desired new charging stations and their maintenance.

Allego’s business model is predicated on the presence of qualified and capable electrical and civil contractors and subcontractors in the new markets it intends to enter. There is no guarantee that there will be an adequate supply of such partners. A shortage in the number of qualified contractors may impact the viability of Allego’s business plan, increase risks around the quality of work performed and increase costs if outside contractors are brought into a new market.

Allego’s business is subject to risks associated with increased cost of land and competition from third-parties that can create cost overruns and delays and can decrease the value of some of Allego’s charging stations.

Allego typically enters into long-term leases for its charging stations. With the growing adoption of EVs, increased competition may develop in securing suitable sites for charging stations, especially in high traffic

18

areas. This competition may trigger increases in the cost of land leases, tenders organized by landowners, delays in securing sites and a quicker depletion of available sites for Allego’s charging stations. The term of leases may also be impacted by increased competition. This could negatively impact the potential economic return of building such charging stations in certain zones or on certain sites and therefore negatively impact Allego’s business and profitability.

Allego’s business is subject to risks associated with the price of electricity, which may hamper its profitability and growth.

Allego obtains electricity for its own charging stations through contracts with power suppliers or through direct sourcing on the market. In most of the countries in which Allego operates, there are many suppliers, which can offer medium or long-term contracts that can allow Allego to hedge the price of electricity. However, market conditions may change, triggering fluctuations and global increases in the price of electricity. For example, the price of electricity is generally higher in the winter due to higher electricity demands, and Europe has recently seen record electricity price increases caused in part by the Russia/Ukraine conflict. While these costs could be passed on to EV customers, increases in the price of electricity could result in near-term cash flow strains to Allego. In addition, global increases in electricity pricing will increase the price of charging, which could impact demand and hamper the use of public charging by EV customers, thus decreasing the number of charging sessions on Allego’s charging stations and adversely impacting its profitability and growth. Furthermore, competitors may be able to source electricity on better terms than Allego which may allow those competitors to offer lower prices for charging, which may also decrease the number of charging sessions on Allego’s charging stations and adversely impact 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.

The operation and development of Allego’s charging points is dependent upon the availability of electricity, which is beyond its control. Allego’s charging points are affected by problems accessing electricity sources, such as planned or unplanned power outages or limited grid capacity. In the event of a power outage, Allego will be dependent on the grid operator, and in some cases the site host, to restore power for its BtoB solutions or to unlock grid capacity. Any prolonged power outage or limited grid capacity could adversely affect customer experience and Allego’s business and results of operations.

Allego’s public charging points are often located in areas that must be freely accessible and may be exposed to vandalism or misuse by customers or other individuals, which would increase Allego’s replacement and maintenance costs.

Allego’s public charging points may be exposed to vandalism or misuse by customers and other individuals, increasing wear and tear of the charging equipment. Such increased wear and tear could shorten the usable lifespan of the chargers and require Allego to increase its spending on replacement and maintenance costs.

Allego’s EV driver base will depend upon the effective operation of Allego’s EVCloud^TM platform and its applications with mobile service providers, firmware from hardware manufacturers, mobile operating systems, networks and standards that Allego does not control.

Allego is dependent on the interoperability of mobile service providers for the payment of charging sessions that must use open protocols. Its own mobile payment application is dependent upon popular mobile operating systems that Allego does not control, such as Google’s Android and Apple’s iOS software systems, and any changes in such systems that degrade or hamper the functionality of Allego’s products or give preferential treatment to competitive products could adversely affect the usage of Allego’s applications on mobile devices. Changes in standards, such as Open Charge Point Interface or Open Charge Point Protocol, may require Allego

19

to incur development expenses and delay its operations and the potential launch of new services. Continued support and operability of Allego’s charging stations depends upon hardware manufacturers’ firmware of which Allego has no control over. Additionally, in order to deliver high quality services to its customers, it is important that Allego’s products work well with a range of technologies, including various firmware, software, networks and standards that Allego does not control. Allego may not be successful in maintaining and updating its EVCloud^TM platform and may not have sufficient knowledge to effectively keep up with new technologies, systems, networks or standards.

A variety of factors may lead to interruption in service, which could harm Allego’s business.

Computer malware, viruses, physical or electronic break-ins and similar disruptions could lead to interruption and delays in Allego’s operations and loss, misuse or theft of data. Computer malware, viruses, ransomware, hacking and phishing attacks against online networks have become more prevalent and may occur on Allego’s systems in the future and on hardware manufacturers that supply Allego. Any attempts by cyber attackers to disrupt Allego’s operations, services or systems, if successful, could harm its business, introduce liability to data subjects, result in the misappropriation of company funds, be expensive to remedy and damage Allego’s reputation or brand. Insurance may not be sufficient to cover significant expenses and losses related to cyber-attacks. Efforts to prevent cyber attackers from entering computer systems are expensive to implement, and Allego may not be able to cause the implementation or enforcement of such preventions. Though it is difficult to determine what, if any, harm may directly result from any specific interruption or attack, any failure to maintain performance, reliability, security and availability of systems and technical infrastructure may, in addition to other losses, harm Allego’s reputation, brand and ability to operate reliably and to retain customers.

Allego has previously experienced, and may in the future experience, service disruptions, outages and other performance problems due to a variety of factors, including infrastructure changes, third-party service providers, scalability issues with its software tools, human or software errors and capacity constraints. Allego relies on telecom networks to support reliable operation, management and maintenance of its charger network, charging session management, and driver authentication, and payment processing by customers depends on reliable connections with wireless communications networks. As a result, Allego’s operations depend on a handful of public carriers and are exposed to disruptions related to network outages and other communications issues on the carrier networks. Disruptions experienced in the payment chain from authorization to settlement also might cause financial harm, directly or indirectly to Allego. If Allego’s services or charging points are unavailable when users attempt to access them, they may seek other services or networks, which could reduce demand for Allego’s charging stations and services.

Allego has processes and procedures in place designed to enable it to recover from a disaster or catastrophe and continue business operations. However, there are several factors ranging from human error to data corruption that could materially impact the efficacy of such processes and procedures, including by lengthening the period of time that services are partially or fully unavailable to customers and users. It may be difficult or impossible to perform some or all recovery steps and continue normal business operations due to the nature of a particular disaster or catastrophe, especially during peak periods, which could cause additional reputational damages, contractual penalties or loss of revenues, any of which could adversely affect its business and financial results.

While Allego to date has not made significant acquisitions, should it pursue acquisitions in the future, it would be subject to risks associated with acquisitions.

Allego may acquire additional assets such as public charging networks, products, technologies or businesses that are complementary to its existing business or that reinforce its core or adjacent competencies. The process of identifying and consummating acquisitions and the subsequent integration of new assets and businesses into Allego’s own business would require attention from management and could result in a diversion of resources from its existing business, which in turn could have an adverse effect on its operations. Acquired assets or businesses may not generate the expected financial results or the expected technological gains. Key employees of

20

acquired companies may also decide to leave. Acquisitions could also result in the use of cash, potentially dilutive issuances of equity securities, the occurrence of goodwill impairment charges, amortization expenses for other intangible assets and exposure to potential unknown liabilities of the acquired business.

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’s success depends, in part, on its continuing ability to identify, hire, attract, train, develop and retain highly qualified personnel. The inability to do so effectively would adversely affect its business.

Competition for employees can be intense in the various parts of Europe where Allego operates, as there is a high demand of qualified personnel. The ability to attract, hire and retain personnel depends on Allego’s ability to provide competitive compensation. Allego may not be able to attract, assimilate, develop or retain qualified personnel in the future, and failure to do so could adversely affect its business, including the execution of its strategy.

Allego is expanding operations in many countries in Europe, which will expose it to additional tax, compliance, market, local rules and other risks.

Allego’s operations are within the European Union, and it maintains contractual relationships with parts and manufacturing suppliers in Asia. It also operates in the United Kingdom, where it has incurred delays in operations since January 1, 2021 as a result of Brexit, which commenced in 2020. Allego also intends to expand into other EEA countries. Managing this global presence and expansion in Europe requires additional resources and controls, and could subject Allego to certain risks, associated with international operations, including:

21

As a result of these risks, Allego’s current expansion efforts and any potential future international expansion efforts may not be successful.

Inflation could adversely affect Allego’s business and financial results.

Inflation, which increased significantly during 2021 and 2022, could adversely affect Allego by increasing the costs of materials and labor needed to operate Allego’s business and could continue to adversely affect the Company in future periods. If this current inflationary environment continues, there can be no assurance that Allego would be able to recover related cost increases through price increases, which could result in downward pressure on Allego’s operating margins. As a result, Allego’s financial condition, results of operations, and cash flows, could be adversely affected over time.

Certain of Allego’s strategic and development arrangements could be terminated or may not materialize into long-term contract partnership arrangements and may restrict or limit Allego from developing arrangements with other strategic partners.

Allego has arrangements with strategic development partners and collaborators. Some of these arrangements are evidenced by memorandums of understanding, non-binding letters of intent, and early stage agreements that are used for design and development purposes but will require renegotiation at later stages of development, each of which could be terminated or may not materialize into next-stage contracts or long-term contract partnership arrangements. In addition, Allego does not currently have formal agreements with all partners and collaborators that are contemplated in the execution of its business plan. Moreover, existing or future arrangements may contain limitations on Allego’s ability to enter into strategic and development arrangements with other partners. If Allego is unable to maintain such arrangements and agreements, or if such agreements or arrangements contain other restrictions from or limitations on developing arrangements with other strategic partners, its business, prospects, financial condition and operating results may be materially and adversely affected.

Risks Related to the EV Market

New alternative fuel technologies may negatively impact the growth of the EV market and thus the demand for Allego’s charging stations and services.

As a number of European Union regulations have sought to achieve a sharp decrease in CO2 emissions in Europe, consumer acceptance of EVs and other alternative vehicles has been increasing. If new technologies such as hydrogen for light trucks or load transportation develop and are widely adopted, the demand for electric charging could diminish. In addition, the EV fueling model is different than gas or other fuel models, requiring behavioral change and education of influencers, consumers and others such as regulatory bodies. Developments in alternative technologies, such as fuel cells, compressed natural gas or hydrogen may materially and adversely affect demand for EVs and EV charging stations, which in turn would materially and adversely affect Allego’s business, operating results, financial condition and prospects.

22

Allego’s future growth and success is highly correlated with and thus dependent upon the continuing rapid adoption of EVs.

Allego’s future growth is highly dependent upon the adoption of EVs by consumers. The market for EVs is still rapidly evolving, characterized by rapidly changing technologies, competitive pricing and competitive factors, evolving government regulation and industry standards and changing consumer demands and behaviors and the environment generally. Although demand for EVs has grown in recent years, bolstered in part by pro-EV regulations in Europe, there is no guarantee that such demand will continue to grow. If the market for EVs develops more slowly than expected, Allego’s business, prospects, financial condition and operating results would be harmed. The market for EVs could be affected by numerous factors, such as:

In addition, sales of vehicles in the automotive industry can be cyclical, which may affect growth in acceptance of EVs. It is uncertain how macroeconomic factors will impact demand for EVs, particularly since they can be more expensive than traditional fuel-powered vehicles, when the automotive industry globally has been experiencing a recent decline in sales.

Demand for EVs may also be affected by factors directly impacting automobile prices or the cost of purchasing and operating automobiles, such as sales and financing incentives, prices of raw materials and parts and components and governmental regulations, including tariffs, import regulation and other taxes. Volatility in demand may lead to lower vehicle unit sales, which may result in reduced demand for EV charging solutions and therefore adversely affect Allego’s business, financial condition and operating results.

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.

Most European countries provide incentives to end users and purchasers of EVs and EV charging stations in the form of rebates, scrappage schemes for internal combustion engines (“ICEs”), tax credits and other financial incentives. The EV market relies on these governmental rebates, scrappage schemes for ICEs, tax credits and other financial incentives to significantly lower the effective price of EVs and EV charging stations to customers and to support widespread installation of EV charging infrastructure. However, these incentives may expire on a particular date, end when allocated funding is exhausted, or be reduced or terminated as a matter of regulatory or legislative policy. Any reduction in rebates, scrappage schemes for ICEs, tax credits or other financial incentives could reduce the demand for EVs and EV charging stations and as a result, may adversely impact Allego’s business and expansion potential.

23

The EV charging market is characterized by rapid technological change, which requires Allego to continue developing new innovations of its software platform and to keep up with new hardware technologies. Any delays in such development could adversely affect market adoption of its solutions and Allego’s financial results.

Continuing technological changes in battery and other EV technologies or payment technologies could adversely affect adoption of current EV charging technology and/or Allego’s charging network or services. Allego’s future success will depend upon its ability to develop new sites and introduce a variety of new capabilities and innovations to enhance EV drivers experience using its network and its existing services offerings.

As EV technologies change, Allego may need to upgrade or adapt its charging stations technology and introduce new hardware in order to serve vehicles that have the latest technology, in particular battery cell technology, which could involve substantial costs. This could lead Allego to replace some charging hardware before its expected lifespan involving financial costs and reduced return. Even if Allego is able to keep pace with changes in technology and develop new features and services, its research and development expenses could increase and its gross margins could be adversely affected.

Allego cannot guarantee that any new services or features of its software platform will be released in a timely manner or at all, or that if such services or features are released, that they will achieve market acceptance. Delays in delivering new services that meet customer requirements could damage Allego’s relationships with customers and lead them to seek alternative providers. For some customers, delays in delivering new services and features could induce the application of contractual penalties. Delays in introducing innovations or the failure to offer innovative services at competitive prices may cause existing and potential customers to purchase Allego’s competitors’ products or services.

If Allego is unable to devote adequate resources to develop new features and services or cannot otherwise successfully develop features or services that meet customer requirements on a timely basis or that remain competitive with technological alternatives, its charging network or services could lose market share, its revenue will decline, it may experience operating losses and its business and prospects will be adversely affected.

Risks Related to Allego’s Technology, Intellectual Property and Infrastructure

Allego may need to defend against intellectual property infringement or misappropriation claims, which may be time-consuming and expensive.

From time to time, the holders of intellectual property rights may assert their rights and urge Allego to obtain licenses, and/or may bring suits alleging infringement or misappropriation of such rights. There can be no assurance that Allego will be able to mitigate the risk of potential suits or other legal demands by competitors or other third-parties. Accordingly, Allego may consider entering into licensing agreements with respect to such rights, although no assurance can be given that such licenses can be obtained on acceptable terms or at all or that litigation will not occur, and such licenses and/or litigation could significantly increase Allego’s operating expenses. In addition, if Allego is determined to have or believes there is a high likelihood that it has infringed upon or misappropriated a third-party’s intellectual property rights, it may be required to cease making, selling or incorporating certain key components or intellectual property into the products and services it offers, to pay substantial damages and/or royalties, to redesign its products and services, and/or to establish and maintain alternative branding. In addition, to the extent that Allego’s customers and business partners become the subject of any allegation or claim regarding the infringement or misappropriation of intellectual property rights related to Allego’s products and services, Allego may be required to indemnify such customers and business partners. If Allego were required to take one or more such actions, its business, prospects, operating results and financial condition could be materially and adversely affected. In addition, any litigation or claims, whether or not valid, could result in substantial costs, negative publicity and diversion of resources and management attention.

24

Allego’s business may be adversely affected if it is unable to maintain, protect or enforce its rights in its technology and intellectual property.

Allego’s success depends, in part, on Allego’s ability to establish, maintain and protect its rights in its core technology and intellectual property. To accomplish this, Allego relies on, and plans to continue relying on, trade secrets, copyright, trademark and other intellectual property laws, employee and third-party nondisclosure agreements, intellectual property licenses and other contractual rights. Failure to adequately maintain, protect or enforce its rights in its technology and intellectual property could result in competitors offering similar products, potentially resulting in the loss of some of Allego’s competitive advantage and a decrease in revenue which would adversely affect its business, prospects, financial condition and operating results.

Allego cannot guarantee that competitors will not infringe its intellectual property. Despite Allego’s efforts to protect its intellectual property, third-parties may attempt to copy or otherwise obtain and use Allego’s intellectual property or seek court declarations that Allego’s intellectual property is invalid or unenforceable or that they do not infringe upon Allego’s intellectual property. Monitoring unauthorized use of Allego’s intellectual property is difficult and costly and the steps Allego has taken or may take in the future in an effort to prevent infringement or misappropriation may not be successful. From time to time, Allego may have to resort to litigation to enforce its intellectual property, which could result in substantial costs and diversion of our resources, and ultimately may not be successful.

In addition, it is possible that:

Patent, trademark and trade secret laws vary significantly throughout the world. Some foreign countries do not protect intellectual property rights to the same extent as do the laws of the European Union or EEA countries. Further, policing the unauthorized use of its intellectual property in foreign jurisdictions may be difficult or impossible. Therefore, Allego’s intellectual property rights may not be as strong or as easily enforced outside of the European Union and EEA.

The current lack of international standards may lead to uncertainty, additional competition and further unexpected costs.

Lack of industry standards for EV station management, coupled with utilities and other large organizations mandating their own specifications that have not become widely adopted in the industry, may hinder innovation or slow new solutions and services or new feature introduction.

In addition, automobile manufacturers may choose to utilize their own proprietary systems and networks, which could lock out competition for EV charging stations, or use their size and market position to influence the market, which could limit Allego’s market and reach to customers, negatively impacting its business.

Further, should regulatory bodies impose standards that are not compatible with Allego’s infrastructure, it may incur significant costs to adapt its business model to the new regulatory standards, which may require significant time and, as a result, may have a material adverse effect on its revenues or results of operations.

25

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 could materially and adversely affect its business.

Allego may be subject to claims that its charging stations have malfunctioned and persons were injured or purported to be injured. Any insurance that Allego carries may not be sufficient or it may not apply to all situations. Similarly, to the extent that such malfunctions are related to components obtained from third-party vendors, such vendors may not assume responsibility for such malfunctions. In addition, Allego’s customers could be subjected to claims as a result of such incidents and may bring legal claims against Allego to attempt to hold it liable. Any of these events could adversely affect Allego’s brand, relationships with customers, operating results or financial condition.

Across Allego’s solutions and services line, Allego develops equipment solutions and services based on preferred second source or common off-the-shelf vendors. However, due to its design specifications, Allego does rely on certain single source vendors, the unavailability or failure to source from these vendors can pose risks to supply chain or product installation which may negatively impact Allego’s business.

Furthermore, Allego’s software platform is complex and includes a number of licensed third-party commercial and open-source software libraries. Allego’s software has contained defects and errors and may in the future contain undetected defects or errors. Allego is continuing to evolve the features and functionality of its platform through updates and enhancements, and as it does, it may introduce additional defects or errors that may not be detected until after deployment to customers. In addition, if Allego’s products and services, including any updates or patches, are not implemented or used correctly or as intended, inadequate performance and disruptions in service may result.

Any defects or errors in product or services offerings, or the perception of such defects or errors, or other performance problems could result in any of the following, each of which could adversely affect Allego’s business and results of its operations:

Although Allego has contractual protections, such as warranty disclaimers and limitation of liability provisions in many of its agreements with customers and other business partners, such protections may not be

26

uniformly implemented in all contracts and, where implemented, may not fully or effectively protect from claims by customers, business partners or other third-parties. Any insurance coverage or indemnification obligations of suppliers may not adequately cover all such claims or cover only a portion of such claims. A successful product liability, warranty, or similar claim could have an adverse effect on Allego’s business, operating results and financial condition. In addition, even claims that ultimately are unsuccessful could result in expenditure of funds in litigation, divert management’s time and other resources and cause reputational harm.

Allego’s use of “open source” software could subject its proprietary software to general release, adversely affect its ability to sell its products and services, and subject it to possible litigation, claims or proceedings.

Allego relies on some open-source software and libraries, including those issued under the General Public License (or similar “copyleft” licenses) for development of its products and may continue to rely on open source software in the future. Companies that use open source software in connection with their products have, from time to time, faced claims challenging the use of open source software and/or compliance with open source license terms. As a result, third-parties may assert claims against Allego claiming ownership of what Allego believes to be open source software or claiming noncompliance with open source licensing terms. Some open source software licenses may require users who distribute proprietary software containing or linked to open source software to publicly disclose all or part of the source code to such proprietary software and/or make available any derivative works of the open source code under the same open source license, which could include proprietary source code. In such cases, the open source software license may also restrict us from charging fees to licensees for their use of our software. While we monitor the use of open source software and try to ensure that open source software is not used in a manner that would subject our proprietary source code to these requirements and restrictions, such use could inadvertently occur, which may decrease revenue and lessen any competitive advantage Allego has due to the secrecy of its source code.

Further, in addition to risks related to license requirements, use of certain open source software may carry greater technical and legal risks than does the use of third-party commercial software. For example, open source software is generally provided as-is without any support or warranties or other contractual protections regarding infringement or the quality of the code, including the existence of security vulnerabilities. To the extent that Allego’s platform depends upon the successful operation of open source software, any undetected errors or defects in open source software that Allego uses could prevent the deployment or impair the functionality of its systems and injure its reputation. In addition, the public availability of such software may make it easier for attackers to target and compromise Allego’s platform through cyber-attacks. Any of the foregoing risks could materially and adversely affect Allego’s business, prospects, financial condition, results of operations, and cash flows.

Interruptions, delays in service or inability to increase capacity, including internationally, at third-party data center facilities could impair the use or functionality of Allego’s operation, harm its business and subject it to liability.

Allego currently serves customers from third-party data center facilities operated by Microsoft Azure Services (“MAS”) located in the United States, Europe and Canada. In addition to MAS, some Allego services are housed in third-party data centers. Any outage or failure of MAS or of such data centers could negatively affect Allego’s product connectivity and performance. Furthermore, Allego depends on connectivity from its charging stations to its data centers through cellular service providers, such as KPN, a Dutch cellular service provider. Any incident affecting a data center facility’s or a cellular service provider’s infrastructure or operations, whether caused by fire, flood, severe storm, earthquake, power loss, telecommunications failures, breach of security protocols, computer viruses and disabling devices, failure of access control mechanisms, natural disasters, war, criminal act, military actions, terrorist attacks and other similar events could negatively affect the use, functionality or availability of Allego’s services.

Any damage to, or failure of, Allego’s systems, or those of its third-party providers, could interrupt or hinder the use or functionality of its services. Impairment of or interruptions in Allego’s services may reduce

27

revenue, subject it to claims and litigation, cause customers to terminate their subscriptions, and adversely affect renewal rates and its ability to attract new customers. Allego’s business will also be harmed if customers and potential customers believe its products and services are unreliable.

Allego expects to incur research and development costs and devote significant resources to developing new solutions, services and technologies and to enhancing its existing solutions and services, which could significantly reduce its profitability and may never result in revenue to Allego.

Allego’s future growth depends on penetrating new markets, adapting existing products to new applications and customer requirements, and introducing new solutions and services that achieve market acceptance. Allego plans to incur significant research and development costs in the future as part of its efforts to design, develop, manufacture and introduce new solutions and services, new technologies and enhance existing solutions and services. Allego’s development expenses were € 1 million as of June 30, 2022, € 3.0 million in 2021, € 3.1 million in 2020 and € 4.0 million in 2019, respectively, and are likely to be similar in the future. These expenses were related to the development of Allego’s EVCloud^TM platform and have been capitalized as intangible assets. Allego did not incur research expenses in 2021, 2020 and 2019 and has not incurred any research expenses as of June 30, 2022. Further, Allego’s research and development program may not produce successful results, and its new solutions and services or new technologies may not achieve market acceptance, create additional revenue or become profitable. Allego’s potential inability to develop the necessary software and technology systems may harm its competitive position. Allego is also relying on third-party suppliers to develop a number of emerging technologies for use in its products. These technologies are not today, and may not ever be, commercially viable. There can be no assurances that Allego’s suppliers will be able to meet the technological requirements, scalability, quality, production timing, and volume requirements to support its business plan. As a result, Allego’s business plan could be significantly impacted.

Customer-Related Risks

Allego may be unable to increase the demand for its public charging network, which could adversely affect its profitability and growth.

Allego’s development strategy consists, in part, on the rollout of public charging sites with a combination mostly of fast and ultrafast charging capabilities. The growth in utilization of these charging sites is key for the profitability of Allego’s business. If utilization does not increase, if the adoption of fast and ultrafast charging is slower than expected, or if the marketing cost to increase such utilization, either directly or through third-parties, is increasing widely, the profitability and growth of Allego may be adversely affected. The expected premium for fast and ultrafast charging compared to slow charging may be not be realized, hampering the growth of fast and ultrafast charging which may adversely affect Allego’s profitability and growth.

Allego’s business will depend on the utilization of its network by EV drivers and the mobility service providers (“MSPs”) to offer access to Allego’s network. If EV drivers do not continue to use Allego’s network or MSPs do not continue to offer access to Allego’s network, Allego’s business and operating results will be adversely affected.

Allego depends on traffic from EV drivers to charge on its network and from MSPs that facilitate the use of Allego’s network to a larger base of EV drivers. Allego has a very large base of MSPs and is developing its own capacity to be an MSP in order to offer additional services in the future. However, if some MSPs do not offer access to Allego’s network for whatever reason or if EV drivers do not use its network due to pricing or lack of services, among other reasons, the utilization of Allego’s sites will be hampered. EV drivers’ retention on Allego’s network may decline or fluctuate as a result of a number of factors, including satisfaction with software and features, functionality of the charging sites, prices, features and pricing of competing solutions and services, reductions in spending levels, mergers and acquisitions involving networks from competitors and deteriorating general economic conditions. If customers do not use Allego’s charging network or if they opt to use cheaper charging options, its business and operating results will be adversely affected.

28

Failure to effectively expand Allego’s sites could harm its ability to increase revenue.

Allego’s ability to grow the number of EV drivers using its charging network, to expand its customer base, achieve broader market share, grow revenue, and achieve and sustain profitability will depend, to a significant extent, on its ability to effectively expand its site development on the one hand and its sales and marketing operations to customers on the other hand. Site development, sales and marketing expenses represent a significant percentage of its total revenue, and its operating results may suffer if site development, sales and marketing expenditures do not increase to support revenue.

Allego is substantially dependent on its direct development team to develop new sites and sales in order to obtain new customers and contracts. Allego plans to continue to expand its development team with the support of external parties. The proper coordination and efficiency of site prospection is key to increasing Allego’s revenue. Allego may not be able to recruit, hire and retain a sufficient number of site developers, which may adversely affect its ability to expand its charging sites. New sales and marketing personnel will be needed to grow Allego’s services business as well. New hires require significant training and investment before they achieve full productivity, particularly in new sales territories. Allego may be unable to hire or retain sufficient qualified individuals. Furthermore, hiring sales personnel in new markets where Allego seeks to operate can be costly, complex and time-consuming, and requires additional upfront costs that may be disproportionate to the initial revenue expected from those markets. There is significant competition for direct sales personnel. Allego’s ability to achieve significant revenue growth in the future will depend, in large part, on its success in recruiting, training, incentivizing and retaining a sufficient number of qualified direct site developers and sales personnel and on such personnel attaining desired productivity levels within a reasonable amount of time. Allego’s business will be harmed if continuing investment in its site development, sales and marketing capabilities does not generate a significant increase in revenue. Allego’s operations may be unable to cope appropriately with the growth of its operating charging points, preventing it from fully benefitting from such growth. Such limitations might come from external suppliers for software and IT-related services as well as from the capacity of Allego to properly upgrade its software platform. Allego could also face contractual penalties with its services customers if it is unable to meet its contractual obligations as a result of these limitations.

Risks Relating to Ownership of Allego Securities

Allego could be treated as a U.S. corporation or a “surrogate foreign corporation” for U.S. federal income tax purposes as a result of the Business Combination.

Under current U.S. federal income tax law, a corporation is generally considered to be a tax resident in the jurisdiction of its organization or incorporation. Therefore, a corporation organized under the laws of the Netherlands would generally be treated as a non-U.S. corporation (and, therefore, not a U.S. tax resident) for U.S. federal income tax purposes. Section 7874 of the Code and the Treasury Regulations promulgated thereunder, however, contain rules that may cause a non-U.S. corporation that acquires the stock of a U.S. corporation to be treated as a U.S. corporation for U.S. federal income tax purposes under certain circumstances (an “Inverted Corporation”). If Allego were an Inverted Corporation for U.S. federal income tax purposes, among other consequences, it would generally be subject to U.S. federal income tax on its worldwide income, and its dividends, if any, would be subject to taxation by the United States as dividends from a U.S. corporation. Regardless of the application of Section 7874 of the Code, Allego is expected to be treated as a Dutch tax resident for Dutch tax purposes. Consequently, if Allego were an Inverted Corporation for U.S. federal income tax purposes under Section 7874 of the Code, it could be liable for both U.S. and Dutch taxes and dividends paid by Allego to its shareholders could be subject to both U.S. and Dutch withholding taxes.

In addition, even if Allego is not an Inverted Corporation pursuant to Section 7874 of the Code, it may be subject to unfavorable treatment as a “surrogate foreign corporation” (within the meaning of Section 7874(a)(2)(B) of the Code) under certain circumstances (a “Surrogate Foreign Corporation”). If it were determined that Allego is a Surrogate Foreign Corporation for U.S. federal income tax purposes under Section 7874 of the Code and the Treasury Regulations promulgated thereunder, dividends, if any, made by

29

Allego would not qualify for “qualified dividend income” treatment, and U.S. affiliates of Allego, if any, could be subject to increased taxation under Sections 7874 and 59A of the Code.

Allego does not expect to be an Inverted Corporation or Surrogate Foreign Corporation for U.S. federal income tax purposes, and Allego intends to take this position on its tax returns. Allego has not sought and will not seek any rulings from the IRS as to such tax treatment. Further, there can be no assurance that your tax advisor, Allego’s tax advisors, the IRS, or a court will agree with the position that Allego is not an Inverted Corporation or Surrogate Foreign Corporation pursuant to Section 7874 of the Code. Allego is not representing to you that Allego will not be treated as an Inverted Corporation or Surrogate Foreign Corporation for U.S. federal income tax purposes under Section 7874 of the Code. The rules for determining whether a non-U.S. corporation is an Inverted Corporation or Surrogate Foreign Corporation for U.S. federal income tax purposes are complex, unclear, and the subject of ongoing regulatory change. Allego’s intended position is not free from doubt.

If Allego were a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes, U.S. Holders of Ordinary Shares or Assumed Warrants could be subject to adverse U.S. federal income tax consequences.

If Allego is treated as a PFIC within the meaning of Section 1297 of the Code for any taxable year during which a U.S. Holder (as defined in the section entitled “Material U.S. Federal Income Tax Considerations”) holds Ordinary Shares or Assumed Warrants (regardless of whether Allego remains a PFIC for subsequent taxable years), certain adverse U.S. federal income tax consequences, such as taxation at the highest marginal ordinary income tax rates on capital gains and on certain actual or deemed distributions, interest charges on certain taxes treated as deferred and additional reporting requirements may apply to such U.S. Holder. Under certain circumstances, certain elections may be available to U.S. Holders of Ordinary Shares to mitigate some of the adverse tax consequences resulting from PFIC treatment, but U.S. Holders will not be able to make similar elections with respect to the Assumed Warrants.

PFIC status depends on the composition of a company’s income and assets and the fair market value of its assets from time to time, as well as on the application of complex statutory and regulatory rules that are subject to potentially varying or changing interpretations. Based on the projected composition of Allego’s income and assets, including goodwill, Allego expects to take the position that it is not a PFIC for the taxable year of the Business Combination, but such position will not be free from doubt. Allego’s PFIC status for the taxable year of the Business Combination or any subsequent taxable year will not be determinable until after the end of each such taxable year, and Allego cannot assure you that it will not be a PFIC in the taxable year of the Business Combination or in any future taxable year. If Allego were later determined to be a PFIC, you may be unable to make certain advantageous elections with respect to your ownership of Allego Securities that would mitigate the adverse consequences of Allego’s PFIC status, or making such elections retroactively could have adverse tax consequences to you. Allego is not representing to you, and there can be no assurance, that Allego will not be treated as a PFIC for the taxable year of the Business Combination or in any future taxable year. Allego has not sought and will not seek any rulings from the IRS or any opinion from any tax advisor as to such tax treatment. U.S. Holders should consult with, and rely solely upon, their tax advisors to determine the application of the PFIC rules to them and any resultant tax consequences.

For more information about the tax considerations with respect to PFIC classification to Holders, please refer to the section entitled “Material U.S. Federal Income Tax Considerations.”

The issuance of additional ordinary shares in connection with financings, acquisitions, investments, our stock incentive plan, contributions from Madeleine or otherwise Allego shareholders could dilute the ownership and voting power of shareholders.

Allego may need to raise additional financing through loans, securities offerings or additional investments in order to fund its ongoing operations. If Allego chooses to raise additional financing through the issuance of

30

Ordinary Shares, such additional Ordinary Shares or such other securities may be issued at a discount to the market price of Ordinary Shares at the time of issuance. Any issuance of such securities could result in substantial dilution to Allego’s existing shareholders and cause the market price of Ordinary Shares to decline.

The Articles include exclusive jurisdiction and forum selection provisions, which may impact the ability of shareholders to bring actions against us or increase the costs of bringing such actions.

The Articles include exclusive jurisdiction and forum selection provisions, which may impact the ability of shareholders to bring actions against Allego or increase the costs of bringing such actions. The Articles provide that, to the fullest extent permitted by applicable law, and unless Allego consents to the selection of an alternative forum, with respect to any complaint asserting a cause of action arising under the Securities Act or the Exchange Act, the federal courts of the United States will be the exclusive forum for resolving any such complaint. These limitations on the forum in which shareholders may initiate action against us may limit a shareholder’s ability to bring a claim in a judicial forum that it finds favorable and could increase the costs and inconvenience of pursuing claims or otherwise adversely affect a shareholder’s ability to seek monetary or other relief. There is uncertainty as to whether a court would enforce such provisions with respect to the Securities Act or the Exchange Act and the rules and regulations thereunder and a court could decline to enforce these exclusive jurisdiction and forum provisions with respect to such claims. Furthermore, investors are not able to waive compliance with federal securities laws and the rules and regulations thereunder. If a court were to find these provisions to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions.

The securities being offered in this prospectus represent a substantial percentage of our outstanding Ordinary Shares, and the sales of such securities could cause the market price of our Ordinary Shares to decline significantly.

This prospectus relates, among other things, to the offer and resale from time to time by the Selling Securityholders of up to 66,493,170 Ordinary Shares, representing approximately 24.9% of our total outstanding Ordinary Shares, which includes (i) 13,700,000 Ordinary Shares that were issued in exchange for Spartan Founders Stock, originally purchased at a price of approximately $0.002 per share, upon the closing of the Business Combination, (ii) 10,360,227 Ordinary Shares issued to the Private Placement Investors at a price of $10.00 per Ordinary Share on the closing of the Business Combination, (iii) 41,097,994 Ordinary Shares that were issued in exchange for Allego Holding Shares to E8 Investor as compensation under the Special Fees Agreement, based on a value of Allego and its subsidiaries of $10.00 per share, upon the closing of the Business Combination and (iv) 1,334,949 Ordinary Shares that were issued to AP PPW at a price of $11.50 per share on a cashless exercise baiss upon its exercise of 9,360,000 Warrants to purchase Ordinary Shares, which were originally Private Placement Warrants purchased at a price of $1.50 per Private Placement Warrant that were automatically converted into Warrants upon the closing of the Business Combination. The market price for our Ordinary Shares could decline as a result of the sales of our Ordinary Shares being offered in this prospectus, and such declines could be significant.

Prior to the extraordinary meeting of Spartan in connection with the Business Combination, holders of 54,092,418 shares of Spartan Class A Common Stock exercised their right to redeem those shares for cash at a price of approximately $10.00 per share, for an aggregate of $540,984,673, which represented approximately 97.99% of the total Spartan Common Stock then outstanding. The Total Resale Shares represent a substantial percentage of our total outstanding Ordinary Shares as of the date of this prospectus. The sale of all securities being offered in this prospectus could result in a significant decline in the public trading price of our Ordinary Shares. Despite such a decline in the public trading price, the Selling Securityholders may still experience a positive rate of return on the securities they purchased due to the difference in the purchase prices described above. Based on the closing price of our Ordinary Shares on September 29, 2022, which was $4.52 per share, the holders of Ordinary Shares that were issued in exchange for Spartan Founders Stock may experience potential profit of up to $4.52 per Ordinary Share. The Private Placement Investors and the E8 Investor will only experience

31

a profit if the sale price of the Ordinary Shares exceeds $10.00 per share and AP PPW will only experience a profit if the sale price of the Ordinary Shares exceeds $13.00 per share. Even though the current trading price of the Ordinary Shares is close to the price at which the units were issued in Spartan’s initial public offering, the Selling Securityholders may have an incentive to sell because they may still experience a positive rate of return based on the current trading price. The public securityholders may not experience a similar rate of return on the securities they purchase due to differences in the purchase prices and the current trading price.

Financial and Accounting-Related Risks

Allego’s financial condition and results of operations are likely to fluctuate on a quarterly basis in future periods, which could cause its results for a particular period to fall below expectations, resulting in a decline in the price of Ordinary Shares.

Allego’s financial condition and results of operations have fluctuated in the past and may continue to fluctuate in the future due to a variety of factors, many of which are beyond its control.

In addition to the other risks described herein, the following factors could also cause Allego’s financial condition and results of operations to fluctuate on a quarterly basis:

Fluctuations in operating results and cash flow could, among other things, give rise to short-term liquidity issues. In addition, revenue, and other operating results in future quarters may fall short of the expectations of investors and financial analysts, which could have an adverse effect on the price of the Ordinary Shares.

Changes to applicable tax laws and regulations or exposure to additional tax liabilities could adversely affect Allego’s business and future profitability.

Allego conducts operations, directly and through its subsidiaries, within the European Union and the United Kingdom, and Allego and its subsidiaries will therefore be subject to income taxes in such jurisdictions. Allego

32

may also in the future become subject to income taxes in other foreign jurisdictions. Allego’s effective income tax rate could be adversely affected by a number of factors, including changes in the valuation of deferred tax assets and liabilities, changes in tax laws, changes in accounting and tax standards or practices, changes in the composition of operating income by tax jurisdiction, changes in Allego’s operating results before taxes, and the outcome of income tax audits in the jurisdictions in which it operates. Allego will regularly assesses all of these matters to determine the adequacy of its tax liabilities. If any of Allego’s assessments are ultimately determined to be incorrect, Allego’s business, results of operations, or financial condition could be materially adversely affected.

Due to the complexity of multinational tax obligations and filings, Allego and its subsidiaries may have a heightened risk related to audits or examinations by federal, state, provincial, and local taxing authorities in the jurisdictions in which it operates. Outcomes from these audits or examinations could have a material adverse effect on Allego’s business, results of operations, or financial condition.

The tax laws of the jurisdictions in which Allego operates, as well as potentially any other jurisdiction in which Allego may operate in the future, have detailed transfer pricing rules that require that all transactions with related parties satisfy arm’s length pricing principles. Although Allego believes that its transfer pricing policies have been reasonably determined in accordance with arm’s length principles, the taxation authorities in the jurisdictions where Allego carries on business could challenge its transfer pricing policies. International transfer pricing is a subjective area of taxation and generally involves a significant degree of judgment. If any of these taxation authorities were to successfully challenge Allego’s transfer pricing policies, Allego could be subject to additional income tax expenses, including interest and penalties, as well as transfer pricing mismatches. Any such increase in Allego’s income tax expense and related interest and penalties could have a material adverse effect on its business, results of operations, or financial condition.

Allego may also be adversely affected by changes in the relevant tax laws and tax rates, treaties, regulations, administrative practices and principles, judicial decisions, and interpretations thereof, in each case, possibly with retroactive effect.

As a result of Allego’s plans to expand operations, including to jurisdictions in which the tax laws may not be favorable, Allego’s effective tax rate may fluctuate, tax obligations may become significantly more complex and subject to greater risk of examination by taxing authorities or Allego may be subject to future changes in tax laws, in each case, the impacts of which could adversely affect Allego’s after-tax profitability and financial results.

In the event that Allego expands its operating business in the European Union or the United Kingdom, or to other jurisdictions, Allego’s effective tax rates may fluctuate widely in the future. Future effective tax rates could be affected by: operating losses in jurisdictions where no tax benefit can be recorded under IFRS, changes in deferred tax assets and liabilities, changes in tax laws or the regulatory environment, changes in accounting and tax standards or practices, changes in the composition of operating income by tax jurisdiction, and the pre-tax operating results of Allego’s business.

Additionally, Allego’s after-tax profitability and financial results could be subject to volatility or be affected by numerous factors, including (a) the availability of tax deductions, credits, exemptions, refunds and other benefits to reduce tax liabilities, (b) changes in the valuation of deferred tax assets and liabilities, if any, (c) the expected timing and amount of the release of any tax valuation allowances, (d) the tax treatment of stock-based compensation, (e) changes in the relative amount of earnings subject to tax in the various jurisdictions, (f) the potential business expansion into, or otherwise becoming subject to tax in, additional jurisdictions, (g) changes to existing intercompany structure (and any costs related thereto) and business operations, (h) the extent of intercompany transactions and the extent to which taxing authorities in relevant jurisdictions respect those intercompany transactions, and (i) the ability to structure business operations in an efficient and competitive manner. Outcomes from audits or examinations by taxing authorities could have an adverse effect on Allego’s

33

after-tax profitability and financial condition. Additionally, several tax authorities have increasingly focused attention on intercompany transfer pricing with respect to sales of products and services and the use of intangibles. Tax authorities could disagree with Allego’s intercompany charges, cross- jurisdictional transfer pricing or other matters and assess additional taxes. If Allego does not prevail in any such disagreements, its profitability may be affected.

Allego’s after-tax profitability and financial results may also be adversely affected by changes in relevant tax laws and tax rates, treaties, regulations, administrative practices and principles, judicial decisions and interpretations thereof, in each case, possibly with retroactive effect.

Allego’s ability to utilize net operating loss carryforwards and certain other tax attributes may be limited.

The ability of Allego to utilize net operating loss and tax loss carryforwards and other tax attributes (including carry-forward non-deductible interest expenses under the Dutch earnings stripping rule) is conditioned upon Allego’s attaining profitability and generating taxable income. Allego Holding has incurred significant net losses since inception and Allego has and is expected to continue to incur significant losses. Additionally, Allego’s ability to utilize net operating loss and tax loss carryforwards to offset future taxable income may be subject to certain limitations. In this respect, the exact amount of the tax losses of Allego Holding and its Dutch subsidiaries for the financial years 2021and 2022 is not fully clear since the Dutch corporate income tax return for 2021 and 2022 still have to be filed with the Dutch Tax Authorities and the Dutch Tax Authorities still have to review and approve this tax return. That said, the amount of tax losses of Allego Holding and its Dutch subsidiaries with respect to the period prior to the Business Combination has been discussed with the Dutch Tax Authorities and the Dutch Tax Authorities have confirmed that the Business Combination does not result in the application of the Dutch change in ownership rules. As a result, the tax losses incurred prior to the Business Combination and allocable to Allego Holding and its Dutch subsidiaries will remain available for set-off following the Business Combination (and the termination of the Dutch tax group as a result thereof). The Dutch Tax Authorities confirmed the methodology of allocating the tax losses to Allego Holding and its Dutch subsidiaries at the time of the Business Combination in respect of the tax losses (to be) incurred for the financial years 2018, 2019, 2020, 2021 and 2022. However, going forward, these tax losses will only be available for set off against taxable income actually realized by Allego Holding, in respect of tax losses incurred and allocated to Allego Holding, or its relevant Dutch subsidiary, in respect of tax losses incurred and allocated to that Dutch subsidiary.

Furthermore, as of January 1, 2022, an indefinite loss carry forward period applies in the Netherlands. However, both the carry forward and carry back tax loss relief will be limited to 50% of the taxable profit to the extent it exceeds EUR 1 million, calculated per financial year. As a result of transitional law, tax losses incurred in the financial years that started on or after January 1, 2013 and that are still available for carry forward as of January 1, 2022 also fall under the new scheme that entered into effect on January 1, 2022 and will therefore be indefinite.

Allego prepares its financial statements in accordance with IFRS as issued by the IASB, which is different than financial statements prepared in accordance with U.S. GAAP.

The SEC permits foreign private issuers to file financial statements in accordance with IFRS as issued by the International Accounting Standards Board’s (“IASB”). As a foreign private issuer, Allego prepares its financial statements in accordance with IFRS as issued by the IASB. The application by Allego of different accounting standards, a change in the rules of IFRS as issued by the IASB, or in the SEC’s acceptance of such rules, could have a significant effect on Allego’s reported financial results. Additionally, U.S. GAAP is subject to interpretation by the Financial Accounting Standards Board, the American Institute of Certified Public Accountants, the Public Company Accounting Oversight Board, the SEC, and various bodies formed to promulgate and interpret appropriate accounting principles. IFRS are subject to change or revision by the IASB. A change in these principles or interpretations could have a significant effect on Allego’s reported financial results.

34

Allego is an “emerging growth company” and it cannot be certain if the reduced disclosure requirements applicable to emerging growth companies makes the Ordinary Shares less attractive to investors and may make it more difficult to compare performance with other public companies.

Allego is an emerging growth company as defined in the JOBS Act, and is, accordingly exempt from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Investors may find the Ordinary Shares less attractive because Allego relies on these exemptions. If some investors find the Ordinary Shares less attractive as a result of such reliance, there may be a less active trading market for their Ordinary Shares, and the stock price may be more volatile.

An emerging growth company may elect to delay the adoption of new or revised accounting standards. In making this election, Section 102(b)(2) of the JOBS Act allows Allego to delay adoption of new or revised accounting standards until those standards apply to non-public business entities. As a result, the financial statements contained in this prospectus and those that Allego will file in the future may not be comparable to companies that comply with public business entities revised accounting standards effective dates.

Allego will incur significant increased expenses and administrative burdens as a public company, which could have an adverse effect on its business, financial condition and results of operations.

Allego faces increased legal, accounting, administrative and other costs and expenses as a public company that it did not incur as a private company. The Sarbanes-Oxley Act, including the requirements of Section 404, as well as rules and regulations subsequently implemented by the SEC, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules and regulations promulgated and to be promulgated thereunder, the Public Company Accounting Oversight Board and the securities exchanges, impose additional reporting and other obligations on public companies. Compliance with public company requirements will increase costs and make certain activities more time-consuming. A number of those requirements require it to carry out activities Allego has not done previously. In addition, expenses associated with SEC reporting requirements will be incurred. Furthermore, if any issues in complying with those requirements are identified (for example, if the auditors identify a significant deficiency or additional material weaknesses in the internal control over financial reporting), Allego could incur additional costs to rectify those issues, and the existence of those issues could adversely affect its reputation or investor perceptions. In addition, Allego will purchase director and officer liability insurance, which has substantial additional premiums. The additional reporting and other obligations imposed by these rules and regulations increase legal and financial compliance costs and the costs of related legal, accounting and administrative activities. Advocacy efforts by shareholders and third-parties may also prompt additional changes in governance and reporting requirements, which could further increase costs.

Allego has identified material weaknesses in its internal control over financial reporting. If Allego is unable to remediate these material weaknesses, or if Allego identifies additional material weaknesses in the future or otherwise fails to maintain an effective system of internal control over financial reporting, this may result in material misstatements of Allego consolidated financial statements or cause Allego to fail to meet its periodic reporting obligations, which may have an adverse effect on the share price.

As a public company, Allego is required to provide management’s attestation on internal control over financial reporting in its second annual report filed with the SEC. Management may not be able to effectively and timely implement controls and procedures that adequately respond to the increased regulatory compliance and reporting requirements that are now applicable after the Business Combination. If Allego is not able to implement the additional requirements of Section 404(a) of the Sarbanes-Oxley Act in a timely manner or with adequate compliance, it may not be able to assess whether its internal control over financial reporting is effective, which may subject it to adverse regulatory consequences or restatements of its financial statements and could harm investor confidence.

35

In connection with the preparation and audit of Allego’s consolidated financial statements as of and for the years ended December 31, 2021, 2020 and 2019 material weaknesses were identified in its internal control over financial reporting. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Internal Control Over Financial Reporting” of this prospectus. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of Allego’s annual or interim financial statements will not be prevented or detected on a timely basis.

Allego did not design or maintain an effective control environment commensurate with its financial reporting requirements. Specifically, Allego did not maintain a sufficient complement of personnel with an appropriate degree of accounting knowledge, experience and training, including supervision of external consultants, to appropriately analyze, record and disclose accounting matters commensurate with its accounting and reporting requirements.

Additionally, there were the following material weaknesses:

The material weakness related to formal accounting policies, procedures and controls resulted in adjustments to several accounts and disclosures. The IT deficiencies did not result in a material misstatement to the consolidated financial statements, however, the deficiencies, when aggregated, could impact maintaining effective segregation of duties, as well as the effectiveness of IT-dependent controls that could result in misstatements potentially impacting all financial statement accounts and disclosures that would not be prevented or detected. Each of these material weaknesses could result in a misstatement of account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

Allego has begun implementing a plan to remediate these material weaknesses; however, its overall control environment is still immature and may expose it to errors, losses or fraud. These remediation measures are ongoing and include hiring additional IT, accounting and financial reporting personnel and implementing additional policies, procedures and controls. Allego currently cannot estimate when it will be able to remediate these material weaknesses and it cannot, at this time, provide an estimate of the costs it expects to incur in connection with implementing the plan to remediate this material weakness. These remediation measures may be time consuming, costly, and might place significant demands on its financial and operational resources. If Allego is unable to successfully remediate these material weaknesses or successfully rely on outside advisors with expertise in these matters to assist it in the preparation of its financial statements, the financial statements could

36

contain material misstatements that, when discovered in the future, could cause Allego to fail to meet its future reporting obligations and cause the trading price of Ordinary Shares to decline.

Allego’s independent registered public accounting firm is not required to formally attest to the effectiveness of its internal control over financial reporting until after it is no longer an “emerging growth company” as defined in the JOBS Act. At such time, Allego’s independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which its internal control over financial reporting is documented, designed or operating. Any failure to maintain effective disclosure controls and internal control over financial reporting could adversely affect the business and operating results and could cause a decline in the trading price of Ordinary Shares.

Risks Related to Legal Matters and Regulations

Members of Allego’s management have limited experience in operating a public company.

Allego’s executive officers have limited experience in the management of a publicly-traded company. The management team may not successfully or effectively manage the transition to a public company that will be subject to significant regulatory oversight and reporting obligations under federal securities laws. Prior to the Business Combination, Spartan failed to timely file its Form 10-Q for the quarter ended March 31, 2021. Our management team’s limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage as an increasing amount of their time may be devoted to complying with such laws, which will result in less time being devoted to the management of the company. Allego does not currently have adequate personnel with the appropriate level of knowledge, experience and training in the accounting policies, practices or internal control over financial reporting required of public companies. The development and implementation of the standards and controls and the hiring of experienced personnel necessary to achieve the level of accounting standards required of a public company may require costs greater than expected.

Privacy concerns and laws, or other domestic or foreign regulations, may adversely affect Allego’s business.

Transnational organizations such as the European Union, national and local governments and agencies in the countries in which Allego and its customers operate or reside have adopted, are considering adopting, or may adopt laws and regulations regarding the collection, use, storage, processing and disclosure of information regarding consumers and other individuals, which could impact its ability to offer services in certain jurisdictions. Laws and regulations relating to the collection, use, disclosure, security and other processing of individuals’ information can vary significantly from jurisdiction to jurisdiction and are particularly stringent in Europe. The costs of compliance with, and other burdens imposed by, laws, regulations, standards and other obligations relating to privacy, data protection and information security are significant. In addition, some companies, particularly larger enterprises, often will not contract with companies that do not meet these rigorous standards. Accordingly, the failure, or perceived inability, to comply with these laws, regulations, standards and other obligations may limit the use and adoption of Allego’s solutions, reduce overall demand, lead to regulatory investigations, litigation and significant fines, penalties or liabilities for actual or alleged noncompliance, or slow the pace at which we close sales transactions, any of which could harm its business. Moreover, if Allego or any of its employees or contractors fail or are believed to fail to adhere to appropriate practices regarding customers’ data, it may damage its reputation and brand.

Additionally, existing laws, regulations, standards and other obligations may be interpreted in new and differing manners in the future, and may be inconsistent among jurisdictions. Future laws, regulations, standards and other obligations, and changes in the interpretation of existing laws, regulations, standards and other obligations could result in increased regulation, increased costs of compliance and penalties for non-compliance, and limitations on data collection, use, disclosure and transfer for Allego and its customers.

37

Additionally, the EU adopted the GDPR in 2016, which became effective in May 2018. The GDPR establishes requirements applicable to the handling of personal data and imposes penalties for non-compliance of up to the greater of € 20 million or 4% of worldwide revenue. The costs of compliance with, and other burdens imposed by, the GDPR may limit the use and adoption of Allego’s solutions and services and could have an adverse impact on its business. Although Allego initiated a compliance program designed to ensure GDPR compliance, Allego may remain exposed to ongoing legal risks related to GDPR and any amendments that may be made by the European Union.

Furthermore, the European Union has adopted in 2020 a European Strategy for Data that may lead to further regulation of data use. The costs of compliance with, and other burdens imposed by, these new regulations may limit the use and adoption of Allego’s solutions and services and could have an adverse impact on its business.

The costs of compliance with, and other burdens imposed by, laws and regulations relating to privacy, data protection and information security that are applicable to the businesses of customers may adversely affect ability and willingness to process, handle, store, use and transmit certain types of information, such as demographic and other personal information.

In addition to government activity, privacy advocacy groups, the technology industry and other industries have established or may establish various new, additional or different self-regulatory standards that may place additional burdens on technology companies. Customers may expect that Allego will meet voluntary certifications or adhere to other standards established by them or third-parties. If Allego is unable to maintain these certifications or meet these standards, it could reduce demand for its solutions and adversely affect its business.

Failure to comply with anticorruption and anti-money laundering laws, including the FCPA, the European Directive (EU) 2015/849, the UK Bribery Act 2010 and similar laws associated with activities inside and outside of the United States and Europe, could subject Allego to penalties and other adverse consequences.

Allego is subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the UK Bribery Act, the European Directive (EU) 2015/849 and possibly other anti-bribery and anti-money laundering laws in countries in which it conducts activities. Allego is subject to regulations and as a result, interacts with foreign officials. In connection therewith, it faces significant risks if it fails to comply with the FCPA and other anti-corruption laws that prohibit companies and their employees and third-party intermediaries from promising, authorizing, offering or providing, directly or indirectly, improper payments or benefits to foreign government officials, political parties and private-sector recipients for the purpose of obtaining or retaining business, directing business to any person or securing any advantage. Any violation of the FCPA, other applicable anti-corruption laws, and anti-money laundering laws could result in whistleblower complaints, adverse media coverage, investigations, loss of export privileges, or severe criminal or civil sanctions, which could have a materially adverse effect on Allego’s reputation, business, operating results and prospects. In addition, responding to any enforcement action may result in a significant diversion of management’s attention and resources, significant defense costs and other professional fees.

Failure to comply with laws relating to employment could subject Allego to penalties and other adverse consequences.

Allego is subject to various employment-related laws in the jurisdictions in which its employees are based. It faces risks if it fails to comply with applicable regional, federal or state wage laws. Any violation of applicable wage laws or other labor- or employment-related laws could result in complaints by current or former employees, adverse media coverage, investigations and damages or penalties which could have a materially adverse effect on Allego’s reputation, business, operating results and prospects. In addition, responding to any such proceeding may result in a significant diversion of management’s attention and resources, significant defense costs and other professional fees.

38

Existing and future environmental and health and safety laws and regulations could result in increased compliance costs or additional operating costs or construction costs and restrictions. Failure to comply with such laws and regulations may result in substantial fines or other limitations that may adversely impact Allego’s financial results or results of operation.

Allego and its operations, as well as those of Allego’s contractors, suppliers and customers, are subject to certain environmental laws and regulations, including laws related to the use, handling, storage, transportation and disposal of wastes including electronic wastes and hardware, whether hazardous or not. These laws may require Allego or others in Allego’s value chain to obtain permits and comply with procedures that impose various restrictions and obligations that could materially affect Allego’s operations. If key permits and approvals cannot be obtained on acceptable terms, or if other operational requirements cannot be met in a manner satisfactory for Allego’s operations or on a timeline that meets Allego’s commercial obligations, it may adversely impact its business.

Environmental and health and safety laws and regulations can be complex and may be subject to change, such as through new requirements enacted at the supranational, national, sub-national and/or local level or new or modified regulations that may be implemented under existing law. The nature and extent of any changes in these laws, rules, regulations and permits may be unpredictable and may have material effects on Allego’s business. Future legislation and regulations or changes in existing legislation and regulations, or interpretations thereof, including those relating to hardware manufacturing, electronic waste or batteries, could cause additional expenditures, restrictions and delays in connection with Allego’s operations, the extent of which cannot be predicted.

Further, Allego currently relies on third-parties to ensure compliance with certain environmental laws, including those related to the disposal of hazardous and non-hazardous wastes. Any failure to properly handle or dispose of such wastes, regardless of whether such failure is Allego’s or its contractors, may result in liability under environmental laws pursuant to which liability may be imposed without regard to fault or degree of contribution for the investigation and clean-up of contaminated sites, as well as impacts to human health and damages to natural resources. Additionally, Allego may not be able to secure contracts with third-parties to continue their key supply chain and disposal services for our business, which may result in increased costs for compliance with environmental laws and regulations.

Increasing attention to Environmental, Social and Governance (“ESG”) matters may adversely impact Allego’s business.

Increasing attention to, and societal expectations on companies to address, climate change and other environmental and social impacts and investor and societal expectations regarding voluntary ESG disclosures may result in increased costs and impact access to capital. While Allego may announce various voluntary ESG targets in the future, such targets are aspirational. Allego may not be able to meet such targets in the manner or on such a timeline as initially contemplated, including, but not limited to as a result of unforeseen costs or technical difficulties associated with achieving such results. To the extent that Allego does meet such targets, this may be achieved through various contractual arrangements, including the continued purchase or various credits or offsets that may be deemed to mitigate Allego’s ESG impact instead of actual changes in Allego’s direct ESG performance (e.g. greenhouse gas emissions). Certain stakeholders may have a negative perception of ESG targets being achieved via such mechansims, and that perception may impact Allego’s business and financial condition.

In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on their approach to ESG matters. These ratings are often developed in a manner that can make it challenging to predict a company’s performance, and unfavorable ESG ratings could lead to increased negative investor sentiment toward the Company and could impact Allego’s access to and costs of capital. Additionally, to the extent ESG matters negatively impact Allego’s reputation, Allego may not be able to compete as effectively to recruit or retain employees, which may adversely affect Allego’s business. ESG matters may also impact Allego’s suppliers, which may lead to Allego being required or choosing to change suppliers that may otherwise have been the most economically efficient, which may in turn adversely impact Allego’s business and financial condition.

39

New climate disclosure rules proposed by the SEC and further ESG-related regulation may increase Allego’s costs of compliance and adversely impact Allego’s business.

On March 21, 2022, the SEC proposed new rules relating to the disclosure of a range of climate-related risks. Public comments were due by June 17, 2022 and the SEC is currently finalizing the new rules, which are expected to be effective in December 2022. Allego is currently assessing the rule, but at this time Allego cannot predict the costs of implementation or any potential adverse impacts resulting from the rule. Further, similar disclosure obligations have been implemented, and have been proposed, in other jurisdictions (including in the EU and the UK). To the extent this rule is finalized in its current or similar form (and/or similar rules are maintained or implemented in other jurisdictions), Allego could incur increased costs relating to the assessment and disclosure of climate-related risks and costs related to greenhouse gas emissions accounting and disclosures regarding Allego’s use of tax deductions, credits, exemptions, refunds and other benefits to reduce tax liabilities. Allego may also face increased litigation risks related to disclosures made pursuant to the rule if finalized as proposed. Similar risks may also apply to Allego in relation to its obligations to comply with existing and future climate and ESG-related regulation across a number of jurisdictions.

We are a foreign private issuer and, as a result, we are not subject to U.S. proxy rules and are subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. domestic public company.

We are a foreign private issuer and, as a result, we are not subject to U.S. proxy rules and are subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. domestic public company. Because we are a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including (i) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act, (ii) the sections of the Exchange Act requiring insiders to file public reports of their share ownership and trading activities and liability for insiders who profit from trades made in a short period of time and (iii) the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q containing unaudited financial and other specified information. In addition, foreign private issuers are not required to file their annual report on Form 20-F until 120 days after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year and U.S. domestic issuers that are large accelerated filers are required to file their annual report on Form 10-K within 60 days after the end of each fiscal year. Foreign private issuers are also exempt from Regulation FD, which is intended to prevent issuers from making selective disclosures of material information. As a result of all of the above, you may not have the same protections afforded to shareholders of a company that is not a foreign private issuer.

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses.

We are a foreign private issuer, and therefore, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act. The determination of foreign private issuer status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter, and, accordingly, the next determination will be made with respect to us on June 30, 2023. In the future, we would lose our foreign private issuer status if (i) more than 50% of our outstanding voting securities are owned by U.S. residents and (ii) a majority of our directors or executive officers are U.S. citizens or residents, or we fail to meet additional requirements necessary to avoid loss of foreign private issuer status. If we lose our foreign private issuer status, we will be required to file with the SEC periodic reports and registration statements on U.S. domestic issuer forms, which are more detailed and extensive than the forms available to a foreign private issuer. We will also have to mandatorily comply with U.S. federal proxy requirements, and our officers, directors and principal shareholders will become subject to the short-swing profit disclosure and recovery provisions of Section 16 of the Exchange Act. In addition, we will lose our ability to rely upon exemptions from certain

40

corporate governance requirements under the listing rules of NYSE. As a U.S. listed public company that is not a foreign private issuer, we will incur significant additional legal, accounting and other expenses that we will not incur as a foreign private issuer, and accounting, reporting and other expenses in order to maintain a listing on a U.S. securities exchange. These expenses will relate to, among other things, the obligation to present our financial information in accordance with U.S. GAAP in the future.

As we are a “foreign private issuer” and may follow certain home country corporate governance practices, our shareholders may not have the same protections afforded to shareholders of companies that are subject to all NYSE governance requirements.

As a foreign private issuer, we have the option to follow certain home country corporate governance practices rather than those of NYSE, provided that we disclose the requirements we are not following and describe the home country practices we are following. We rely or may rely, as applicable, on this “foreign private issuer exemption” with respect to the NYSE requirements with respect to shareholder meeting quorums, shareholder approval and certain board, committee and director independence requirements. However, we may in the future elect to follow home country practices with regard to other matters. As a result, our shareholders may not have the same protections afforded to shareholders of companies that are subject to all NYSE corporate governance requirements.

The JOBS Act permits “emerging growth companies” and “smaller reporting companies” like us to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies or smaller reporting companies.

We qualify as an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the JOBS Act. As such, we take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies, including (a) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404 of the Sarbanes- Oxley Act, (b) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (c) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. As a result, our shareholders may not have access to certain information they deem important. We will remain an emerging growth company until the earliest of (a) the last day of the fiscal year (i) following the fifth anniversary of the effectiveness of the Form F-4, (ii) in which we have total annual gross revenue of at least $1.07 billion (as adjusted for inflation pursuant to SEC rules from time to time) or (iii) in which we are deemed to be a large accelerated filer, which means the market value of our Ordinary Shares that is held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (b) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three year period.

In addition, Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act as long as we are an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Further, we qualify as a “smaller reporting company” as defined in Regulation S-K under the Securities Act and may take advantage of certain of the scaled disclosures available to smaller reporting companies. We may be a smaller reporting company even after we are no longer an emerging growth company.

41

We cannot predict if investors will find our Ordinary Shares less attractive because we will rely on these exemptions. If some investors find our Ordinary Shares less attractive as a result, there may be a less active trading market for our Ordinary Shares and our stock price may be more volatile.

The exclusive forum clause set forth in the 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.

The Warrant Agreement provides that (i) any action, proceeding or claim against Allego arising out of or relating in any way to the Warrant Agreement will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York and (ii) Allego irrevocably submits to such jurisdiction, which jurisdiction will be exclusive. Allego has waived or will waive any objection to such exclusive jurisdiction or that such courts represent an inconvenient forum. We note, however, that there is uncertainty as to whether a court would enforce these provisions and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Section 22 of the Securities Act creates concurrent jurisdiction for state and federal courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

Notwithstanding the foregoing, these provisions of the Warrant Agreement will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Any person or entity purchasing or otherwise acquiring any interest in any of the Assumed Warrants shall be deemed to have notice of and to have consented to the forum provisions in the Warrant Agreement. If any action, the subject matter of which is within the scope of the forum provisions of the Warrant Agreement, is filed in a court other than a court of the State of New York or the United States District Court for the Southern District of New York (a “foreign action”) in the name of any holder of the Assumed Warrants, such holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located in the State of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant holder.

This choice-of-forum provision may limit a warrant holder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with Allego, which may discourage such lawsuits. Alternatively, if a court were to find this provision of the Warrant Agreement inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could materially and adversely affect our business, financial condition and results of operations and result in a diversion of the time and resources of our management and board of directors.

Future sales, or the perception of future sales, of our Ordinary Shares being offered in this prospectus by us or the Selling Securityholders or pursuant to future offerings by shareholders with registration rights could cause the market price for our Ordinary Shares and Warrants to decline significantly.

The sale of substantial amounts of our Ordinary Shares being offered in this prospectus, or the perception that such sales could occur, could harm the prevailing market price of our Ordinary Shares and Warrants. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. We believe the likelihood that Warrant holders will exercise their Warrants, and therefore the amount of cash proceeds that we would receive, is dependent upon the market price of our Ordinary Shares. If the market price for our Ordinary Shares is less than $11.50 per share, we believe the Warrant holders will be less likely to exercise their Warrants. As of September 29, 2022, the closing price of our Ordinary Shares was $4.52. In addition, the Ordinary Shares owned

42

by Madeleine, which are not being offered in this prospectus, constitute approximately 74.1% of the outstanding Ordinary Shares and are subject to future registration rights, and any future registration of such Ordinary Shares could cause a significant decline in the market trading price for our Ordinary Shares.

Pursuant to the terms of the Letter Agreement Amendment entered into in connection with the execution of the Business Combination Agreement, each Insider party thereto agreed, effective as of the Closing and subject to certain exceptions, to modify the lock-up restrictions set forth in the Existing Letter Agreement such that such Insider will agree not to Transfer (as defined in the Letter Agreement Amendment) any Ordinary Shares issued to such Insider in respect of any shares of Spartan Class A Common Stock that may be received by such Insider at the Closing upon conversion of the Spartan Founders Stock pursuant to the Business Combination Agreement until (i) six months after the Closing or (ii) earlier if (a) the last reported sale price of Ordinary Shares equals or exceeds $12.00 per share for any 20 trading days within a 30-day trading period commencing at least 120 days after the Closing Date, (b) Allego consummates a subsequent liquidation, merger, stock exchange or other similar transaction which results in all Allego’s shareholders having the right to exchange their Ordinary Shares for cash, securities, or other property or (c) the Board determines that the earlier termination of such restrictions is appropriate. Under the Letter Agreement Amendment, each Insider also agreed, effective as of the Closing and subject to certain exceptions, to modified transfer restrictions prohibiting the Transfer of any Assumed Warrants, and any Ordinary Shares underlying any Assumed Warrants, until 30 days after the Closing Date.

Furthermore, pursuant to the Registration Rights Agreement, each of Madeleine and E8 Investor have agreed to the following lock-up restrictions:

As restrictions on resale end, the market trading price for our Ordinary Shares and Warrants could drop significantly if the holders of the Ordinary Shares being offered in this prospectus, or the Ordinary Shares owned by Madeleine, are sold or are perceived by the market as intending to be sold. These factors could also make it more difficult for us to raise additional funds through future offerings of our Ordinary Shares or other securities.

The grant and future exercise of registration rights may adversely affect the market price of Ordinary Shares.

Pursuant to the Registration Rights Agreement entered into by Allego, the Sponsor, Madeleine, E8 Investor and certain other holders of Ordinary Shares (collectively, the “Registration Rights Holders”) in connection with the Business Combination, and which is described elsewhere in this prospectus, Registration Rights Holders that hold registrable securities having an aggregate value of at least $50 million can demand that Allego register their registrable securities under certain circumstances, and each Registration Rights Holder will also have piggyback registration rights for these securities in connection with certain registrations of securities that Allego undertakes. In addition, Allego is required to file and maintain an effective registration statement under the Securities Act

43

covering such securities and certain other securities of Allego. The registration of these securities will permit the public sale of such securities. The registration and availability of such a significant number of securities for trading in the public market may have an adverse effect on the market price of the Ordinary Shares.

Madeleine owns a significant amount of Allego’s voting shares and its interests may conflict with those of other shareholders.

Madeleine owns approximately 74.1% of the outstanding Ordinary Shares and has the right to direct the voting of an additional approximately 15.4% of the outstanding Ordinary Shares as a result of the irrevocable voting power of attorney granted by E8 Investor to Madeleine. As a result, Madeleine will be able to control matters requiring shareholder or board approval, including the election of directors, approval of any potential acquisition of Allego, changes to Allego’s organizational documents and significant corporate transactions. This concentration of ownership and voting power makes it unlikely that any other holder or group of holders of Allego’s securities will be able to affect the way Allego is managed or the direction of its business. The interests of Madeleine with respect to matters potentially or actually involving or affecting Allego, such as future acquisitions, financings and other corporate opportunities and attempts to acquire Allego may conflict with the interests of other shareholders. In particular, Meridiam, which is the general partner of the funds that control Madeleine, and such funds are in the business of making investments in companies and may acquire and hold interests in businesses that compete directly or indirectly with Allego. Meridiam, such funds and their respective affiliates may also pursue acquisition opportunities that may be complementary to Allego’s business (and, as a result, those acquisition opportunities may not be available to Allego) or may have an interest in Allego pursuing acquisitions, divestitures or other transactions that, in their judgment, could enhance their investment, even though such transactions might involve risks to you.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

For purposes of this section, Allego N.V. is referred to as “Allego” and Allego Holding B.V. is referred to as “Allego Holding”.

Introduction

The following unaudited pro forma condensed combined financial information is provided to aid you in your analysis of the financial aspects of the Business Combination. The following unaudited pro forma condensed combined financial information presents the combination of the financial information of Spartan and Allego Holding B.V. (“Allego Holding”) adjusted to give effect to the Business Combination and related transactions. The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.”

The unaudited pro forma condensed combined statement of financial position as of December 31, 2021 gives pro forma effect to the Business Combination as if it had been consummated as of that date. The unaudited pro forma condensed combined income statement for the twelve months ended December 31, 2021 gives pro forma effect to the Business Combination as if it had occurred as of January 1, 2021, the beginning of the earliest period presented.

Unaudited pro forma condensed combined financial information has not been presented for the six months ended June 30, 2022. The Business Combination closed on March 16, 2022, and the impact of the Business Combination is reflected in the condensed consolidated financial statements for the six months ended June 30, 2022 and 2021 included in this prospectus. Had the Closing occurred instead on January 1, 2022, the only Pro Forma Transaction Accounting Adjustments to report here would be € 8 thousand elimination of interest income earned on the balance held within the trust account, representing the difference in interest income earned for the period between January 1, 2022 and the Closing of the Business Combination.

The unaudited pro forma condensed combined financial information has been presented for illustrative purposes only and is not necessarily indicative of the financial position and results of operations that would have been achieved had the Business Combination and related transactions occurred on the dates indicated. Further, the unaudited pro forma condensed combined financial information may not be useful in predicting the future financial condition and results of operations of the post-combination company. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date of the unaudited pro forma condensed combined financial information and is subject to change as additional information becomes available and analyses are performed. This information should be read in conjunction with Spartan and Allego Holding’s respective audited financial statements and related notes.

The unaudited pro forma condensed combined statement of financial position as of December 31, 2021 and the unaudited pro forma condensed combined income statement for the twelve months ended December 31, 2021 have been prepared using the following:

The unaudited pro forma adjustments are based on information currently available. The assumptions and estimates underlying the unaudited pro forma adjustments are described in the accompanying notes. Actual results may differ materially from the assumptions used to present the unaudited pro forma condensed combined financial information. Management of Allego Holding and Spartan have made significant estimates and

45

assumptions in the determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information has been prepared based on these estimates, the final amounts recorded may differ materially from the information presented. This unaudited pro forma condensed combined financial information should be read in conjunction with the financial information included elsewhere in this prospectus.

Description of the Business Combination

For a description of the Business Combination see “Prospectus Summary – Recent Developments – Business Combination.”

Anticipated Accounting Treatment

The Business Combination will be accounted for as a capital reorganization in accordance with IFRS. Under this method of accounting, Spartan will be treated as the “acquired” company for accounting purposes. As Spartan does not meet the definition of a business under IFRS, the net assets of Spartan will be stated at historical cost, with no goodwill or other intangible assets recorded. As a result of the Business Combination and related transactions, the existing shareholders of Allego Holding will continue to retain control through their majority ownership of Allego.

Allego Holding has been determined to be the accounting acquirer based on an evaluation of the following facts and circumstances:

The Business Combination, which is not within the scope of IFRS 3 since Spartan does not meet the definition of a business in accordance with IFRS 3, is accounted for within the scope of IFRS 2. Any excess of the fair value of Ordinary Shares issued to Spartan Stockholders over the fair value of Spartan’s identifiable net assets acquired represents compensation for the service of a stock exchange listing for its shares provided by Spartan and is expensed as incurred.

Basis of Pro Forma Presentation

The adjustments presented on the pro forma combined financial statements have been identified and presented to provide an understanding of Allego upon consummation of the Business Combination for illustrative purposes.

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” Release No. 33-10786 replaces the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). We have elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the following unaudited pro forma condensed combined financial information.

The pro forma combined financial information is for illustrative purposes only. The financial results may have been different had the companies always been combined. You should not rely on the unaudited pro forma combined financial information as being indicative of the historical results that would have been achieved had the companies always been combined or the future results that Allego will experience. Spartan and Allego

46

Holding have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The historical financial information of Spartan has been adjusted to give effect to the differences between U.S. GAAP and IFRS for the purposes of the combined pro forma financial information. The only adjustment required to convert Spartan’s financial statements from U.S. GAAP to IFRS for purposes of the combined pro forma financial information was to reclassify shares of Spartan Class A Common Stock subject to redemption to non-current liabilities in accordance with IFRS. The adjustments presented in the pro forma combined financial information have been identified and presented to provide relevant information necessary for an accurate understanding of Allego after giving effect to the Business Combination.
