Financial Information; Non-GAAP Financial Measures

This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles ("GAAP") including, but not limited to, EBITDA and EBITDA Margin. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing Alternus's financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that the presentation of these measures may not be comparable to similarly-titled measures used by other companies.

Clean Earth and Alternus believe these non-GAAP measures provide useful information to management and investors regarding certain financial and business trends relating to Alternus's financial condition and results of operations. Clean Earth and Alternus believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing Alternus's financial results with other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures.

This Presentation also includes certain projections of non-GAAP financial measures. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, Clean Earth and Alternus are unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward-looking non-GAAP financial measures is included.

Certain monetary amounts, percentages and other figures included in this Presentation have been subject to rounding adjustments. Certain other amounts that appear in this Presentation may not sum due to rounding.

Use of Projections

This Presentation contains financial forecasts with respect to Clean Earth and Alternus's projected financial results, including Revenue, EBITDA and EBITDA Margin. Neither Clean Earth's nor Alternus's independent auditors have audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this Presentation. These projections should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of Alternus or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved.

Industry and Market Data

This Presentation includes certain information and statistics obtained from third-party sources. None of Clean Earth or Alternus has independently verified the accuracy or completeness of any such third-party information.

Trademarks

TRANSACTION OVERVIEW Transaction Overview 8

Summary & Structure

  • Alternus Energy Group ("Alternus") and Clean Earth Acquisitions Corp. ("CLIN") have executed a Business Combination Agreement setting forth the terms and conditions of a business combination (the "Transaction") pursuant to which CLIN will acquire substantially all of Alternus' subsidiaries, other than certain excluded subsidiaries
  • Alternus is expected to receive ~64% of the pro forma equity (excluding shares which may be released from an escrow account if earnout targets are met)
  • Expected to close in the first quarter of 2023

Valuation

  • Transaction implies a fully diluted pro forma enterprise value (EV) of ~\$992.0 million, with implied valuation multiples of:
  • 21.0x 2023 Full Year Pro Forma EBITDA of \$47.2 million1
  • 6.6x 2024 Full Year Pro Forma EBITDA of \$149.3 million1
  • Alternus earnout of 35 million shares
  • 8 million shares released from escrow if post-combination entity generates 'Adjusted EBITDA' of \$33 million for the fiscal year ending December 31, 2023 and share price is at least \$11.00 for a minimum number of trading days
  • 12 million shares released from escrow if post-combination entity generates 'Adjusted EBITDA' of \$75 million for the fiscal year ending December 31, 2024 and share price is at least \$13.00 for a minimum number of trading days
  • 15 million shares released from escrow if post-combination entity generates 'Adjusted EBITDA' of \$135 million for the fiscal year ending December 31, 2025 and share price is at least \$15.00 for a minimum number of trading days
  • If the target is missed for 2023 or 2024, but a subsequent target is met, earnout shares attributable to an earlier year will be released from escrow upon meeting of the lateryear target
  • If the Adjusted EBITDA target is met, but the share price target is not met, earn-out can still be earned if the share price target or calculated share price target (based on multiple of Adjusted EBITDA minus net debt) is met during 2028-2030

Capital Structure

Transaction would result in ~\$218.8 million of cash at closing from CLIN trust account, assuming no redemptions

The Alternus Sustainable Arts Initiative was established in 2022 as a tangible application of Alternus Energy's sustainability policy in addition to our work in the renewable sector.

The Initiative was established to foster sustainability in the arts by supporting artists and providing them with a platform to share their work and create value for their art. Artists are tasked with creating art with recycled or repurposed materials. Alternus signed an initial 3-year partnership with NCAD National College of Art and Design in Ireland. Winning artists receive a financial reward, and all artwork is displayed on the initiative's website. The physical artwork is displayed in Alternus Energy's offices and partner offices around the world. See the winning artwork from year one here at https://alternussustainablearts.com

Alternus Energy is committed to supporting the ongoing sustainability of artists in our communities through continuous expansion of the Artistic disciplines that it funds internationally.

Notes: (1) Based on H1 2022 energy production. (2) Alternus uses Meteocontrol Performance Monitoring System to track production from our solar parks. Country-specific electricity grid greenhouse gas emission factors are used alongside production data to calculate the avoided carbon emissions. (3) the average annual carbon offset of 26.635 kg Co2 per tree (Encon) is used to calculate the number of trees required to avoid that level of carbon. (4) The average annual demand for Irish households (4,200 kWh) (Bonkers.ie) is used to calculate the number of homes powered.

REINVESTMENT OF IN -HOUSE INSTALLATION (EPC) MARGINS FURTHER SUPPORTS "SELF -FUNDED" GROWTH

Illustrative Alternus solar park CapEx components and funding sources

  • Alternus typically achieves a gross margin of circa 10% on its EPC activities
  • Reinvestment of this margin in the projects reduces need for new project equity
  • Senior debt remains below 75% LTV which is within normal banking parameters

Organically developed assets will require a lower Projects Rights% of the total costs as Alternus will develop projects in-house. This has the potential to reduce the project equity contribution

IN -HOUSE O&M SERVICE CAPTURES A LARGER SHARE OF PROJECT REVENUE

Illustrative European project cash generation for Alternus for projects with in-house O&M services

  • Alternus benefits from in-house O&M capability by capturing margin otherwise paid to third party providers.
  • Cashflow from projects is available to fund additional construction / acquisition of additional capacity to further grow portfolio and reduce external funding requirements

O&M capability results in Alternus receiving c. 23% of project cashflows over the project life

ROBUST PROJECT FINANCIAL EVALUATION PROCESS ENSURES ALL PROJECTS ARE PROFITABLE OVER THEIR FULL LIFE CYCLE

Projects are ranked 'early and continually' in order to select only those with the 'lowest risk & highest return'.

Investment Metric: Levelized Cost of Electricity (LCOE): LCOE1 can be viewed from an economic perspective as an "average" electricity price (MW-h) that must be earned by a specific generation source to break even. A project will generate positive equity returns where Contracted/Market electricity prices are above the LCOE

  1. The formula to calculate the LCOE is (Present Value of DevEx + CapEx + OpEx Over the Lifetime)/(Present Value of All Electricity Generated Over the Lifetime).

NOTES: Euro: USD conversion rate 1:1 for the forecasted periods. 2021 historical financial statements are based on IFRS audited financial statements converted to USD and US GAAP accounting. 2022 6 months actual is based on IFRS management reported financials converted to USD and US GAAP. See 2022 – 2025 forecast assumptions on page 37

Non-GAAP Measures includes: 'EBITDA' / 'Reported EBITDA' / 'Booked EBITDA' is Earnings Before Interest, Taxes, Depreciation, and Amortization; 'Annualization Adjustment' refers to the EBITDA generated in the first 12 months of operations of any projects that has not been included in the Reported EBITDA. Pro-Forma EBITDA refers to EBITDA plus the Annualization Adjustment as presented in the Non-GAAP Measure Run Rate EBITDA graphs for FY2023(E) and FY2024(E)

2022 – 2025 Forecast Common Assumptions:

  • Production estimates based on 3rd party engineering reports or internal production reports and adjusted for the appropriate panel degradation.
  • Revenues for each project is calculated by multiplying the production by the KW/h energy rates based on a specific offtake agreement or if no offtake agreement, then Alternus uses forecasted energy rates provided by an expert 3rd party.
  • Operations and maintenance (O&M) costs are based on contracted amounts for O&M, land leases, insurance. Other O&M costs is an estimate based on Alternus management's analysis.
  • Asset management costs are estimates based on Alternus management's analysis of what the costs will be to maintain the number of SPV's associated with the project(s).
  • Taxes are based on the specific prevailing tax rates per country.
  • No significant changes in accounting policy or material one-time charges.

2022 Forecast based on the following:

  • Current Projects Owned and Operating 165MWs, plus additional projects in 2022,that are currently under contract, make up the revenue forecast
  • Debt is based on existing bond debt at 6.5% that is expected to be refinanced in H22023 for another 3-year term estimated at the current bond interest rate. At this time it is assumed that the debt will be non-amortizing and mature in H22026. The debt is then assumed to be amortized for 15 – 20 years based on the remaining project life.
  • Corporate overhead is estimated at \$8.0 million for 2022.

2023 Forecast based on the following:

  • The 2023 forecast is generally based on the same assumption as the 2022 forecast, plus additional projects that are currently owned, under contract or exclusive rights in 2023 that make up the revenue forecast. New projects, assumed that Alternus will offtake agreements with investment grade off-takers (BBB- or better) for a least 70% of the production, which is consistent with current projects that do not have a feed in tariff agreement.
  • Debt assumes a twenty-five-year tenor with the first three years being non amortizing based on interest rates and terms available to Alternus today
  • Corporate overhead is estimated at \$10.0 million for 2023.

2024 Forecast based on the following:

  • The 2024 forecast is generally based on the same assumption as the 2023 forecast, plus additional projects that are currently owned, under contract or exclusive rights in 2024 that make up the revenue forecast. New projects, assumed that Alternus will have offtake agreements with investment grade off-takers (BBB- or better) for a least 70% of the production, which is consistent with current projects that do not have a feed-in-tariff agreement.
  • Debt assumes a twenty-five-year tenor with the first three years being non amortizing based on interest rates and terms available to Alternus today
  • Corporate overhead is estimated at \$15.0 million for 2024.

2025 Forecast based on the following:

  • The 2025 forecast is generally based on the same assumption as the 2024 forecast, plus additional projects that are currently owned, under contract or exclusive rights in 2025 that make up the revenue forecast. New projects, assumed that Alternus will have offtake agreements with investment grade off-takers (BBB- or better) for a least 70% of the production, which is consistent with current projects that do not have a feed in tariff agreement.
  • Debt assumes a twenty-five-year tenor with the first three years being non amortizing based on interest rates and terms available to Alternus today
  • Corporate overhead is estimated at \$20.0 million for 2025.

OFFTAKE CONTRACT TYPES - FIT VS. PPA

Appendix 52

Feed-in-Tariff (FiT)

  • A Feed-in Tariff (FiT) is a renewable energy payment that is a policy mechanism designed to accelerate investment in renewable energy technologies
  • It provides the investor with a purchasing guarantee that stipulates a fixed price over the economic life of the power plant
  • This is achieved by offering long-term government-backed contracts to renewable energy producers, typically based on the cost of generation of each technology
  • The duration of the FiT varies between 8-25 years depending on the country, region and technology
  • The FiT rate is not uniform across all renewable energy generating technologies and varies based on numerous criteria and costs
  • In Italy and Germany Alternus current operational parks benefit from a 20-year government-backed FiT under the Conto Energia and EEG respectively. In the Netherlands Alternus operational park benefits from a 15-year government-backed FiT under the SDE+ mechanism

Power Purchase Agreement (PPA)

  • All current PPAs for Alternus operational parks are contracted with a utility or energy supplier as the counterparty. Currently ALTN benefits from both a FiT and PPA payment for its Italian operational assets. The company also benefits from a PPA payment as well as Green Certificates for its operational assets in Romania
  • A utility PPA is the most common form of PPA, whereby an energy generator enters into an agreement with an energy supplier/utility to purchase the energy produced by the generator
  • The contract will stipulate that the generator delivers the power to the energy supplier/utility where the project is physically connected to the grid network
  • The terms of the contract can vary depending on the requirements on the energy generator, but it can be arranged that the energy generator is paid a fixed price per kWh of energy produced
  • The length of the contract can vary and depends on the requirements of the energy generator but generally can be anywhere between 3 up to 10 years

Risk Factors

The list below of risk factors has been prepared solely for purposes of the proposed business combination of Clean Earth Acquisitions Corp. ("Clean Earth") and Alternus Energy Group Plc ("Alternus"), pursuant to which Clean Earth will acquire all of Alternus's interests in its subsidiaries, other than certain excluded subsidiaries (the "Acquired Subsidiaries") (the "Business Combination"). All references to "Alternus," the "Company," "we," "us" or "our" refer to the business of Alternus conducted through the Acquired Subsidiaries and all reference to the Combined Company refer to Clean Earth and the Acquired Subsidiaries after the closing of the Business Combination. The risks presented below are certain of the material risks related to the Company and the Business Combination, and such list is not exhaustive. The list below is qualified in its entirety by disclosures contained in future documents filed or furnished by the Company and Clean Earth, with the U.S. Securities and Exchange Commission ("SEC"), including the documents filed or furnished in connection with the Business Combination. The risks presented in such filings will be consistent with those that would be required for a public company in its SEC filings, including with respect to the business and securities of the Company and Clean Earth and the proposed transactions between the Company and Clean Earth, and may differ significantly from and be more extensive than those presented below.

You should carefully consider these risks and uncertainties, together with the information in the Company's consolidated financial statements and related notes, and should carry out your own due diligence and consult with your own financial and legal advisors concerning the risks and suitability of an investment post-combination company. There are many risks that could affect the business and results of operations of the Company, many of which are beyond its control. If any of these risks or uncertainties occurs, the Company's business, financial condition and/or operating results could be materially and adversely harmed. Additional risks and uncertainties not currently known or those currently viewed to be immaterial may also materially and adversely affect the Company's business, financial condition and/or operating results. If any of these risks or uncertainties actually occurs, the value of the Company's equity securities may decline.

Risks Related to Alternus and the Industry in which It Operates

•Alternus is a holding company that relies on distributions and other payments, advances, and transfers of funds from its subsidiaries to meet its obligations.

•The seasonality of Alternus's operations may affect its liquidity and will affect its quarterly results.

•Failure to manage the Alternus's growing and changing business could have a material adverse effect on the business, prospects, financial condition, and results of operations.

•The delay between making significant upfront investments in Alternus's solar parks and receiving revenue could materially and adversely affect Alternus's liquidity, business and results of operations.

•Alternus's limited operating history may not serve as an adequate basis to judge its prospects and results of operations.

•The holding companies of Alternus and its subsidiaries have a significant number of foreign subsidiaries with whom they have entered into many related party transactions. The relationship of such holding companies with these entities could adversely affect Alternus in the event of their bankruptcy or similar insolvency proceeding.

•Alternus's business as an independent power producer (IPP) requires significant financial resources and the growth prospects and future profitability of Alternus depends on the availability of additional funding options with acceptable terms. Alternus needs to obtain financing to meet these requirements, and there can be no assurance that it will be successful in obtaining such financing on acceptable terms. If Alternus does not successfully execute its financing plan its business and results of operations would be materially and adversely affected.

•If sufficient demand for solar parks does not develop or takes longer than anticipated to develop, Alternus's business, financial condition, results of operations and prospects could be materially and adversely affected. •Alternus may be subject to unforeseen costs, liabilities or obligations when operating and maintaining solar parks.

•Alternus may be subject to the impact of reduction, modification or elimination of government subsidies and economic incentives (including, but not limited to, with respect to on solar parks);

•Alternus may be affected by the impact of decreases in spot market prices for electricity.

•Refurbishment of renewable energy facilities involve significant risks that could result in unplanned power outages or reduced output.

•Business interruptions, whether due to catastrophic disasters or other events, could adversely affect Alternus's operations, financial condition, and cash flows.

•Fluctuations in foreign currency exchange rates may negatively affect the Alternus's revenue, cost of sales and gross margins and could result in exchange losses.

•Alternus has substantial operations outside of the United States which presents specific risks to its business.

•Alternus's business, results of operations, financial condition and cash flows has been and may continue to be materially and adversely affected by the outbreak of COVID-19.

•Alternus's business and results of operations may be affected by inflation and changes in interest rates, an economic slowdown, recession or contraction of the global economy, a financial or liquidity crisis, geopolitical factors,

including, but not limited to, the Russian invasion of Ukraine, global supply chain concerns, and the status of debt and equity markets (including, without limitation, market volatility and uncertainty).

Legal and Regulatory Risks

  • Alternus may, in the ordinary course of business, become involved in such proceedings which may be expensive, lengthy, and disruptive to normal business operations and require significant attention from Alternus's management bodies.
  • Alternus is subject to counterparty risks under our Feed in Tariff (FiT) price support schemes and Green Certificates (GC) schemes.
  • Alternus has limited business insurance coverage internationally.
  • Failure to comply with laws and regulations where Alternus develops, constructs and operates solar power projects may materially and adversely affect our business, results of operations and financial condition.
  • Alternus is subject to anti-corruption, anti-bribery, anti-money laundering, economic and trade sanctions and similar laws. Non-compliance with such laws can subject Alternus to criminal or civil liability and harm our business, revenues, financial condition, and results of operations.
  • Alternus is subject to the laws of each of the foreign jurisdictions in which its Acquired Subsidiaries are organized.
  • Alternus's energy facilities may be located on land which may be subject to government seizure or expropriation.
  • Alternus is subject to the risk of potential disputes with property owners or third parties who otherwise have rights to or interests in the properties used for Alternus's solar parks.

Risks related to Alternus's Financial Situation

  • Alternus's substantial indebtedness could adversely affect its business, financial condition, and results of operations.
  • Alternus will need additional financing to maintain future profitability
  • There can be no assurance or guarantee that Alternus can raise capital or meets is funding needs.

Risks Related to the Business Combination

  • Following the consummation of the Business Combination, the Combined Company's significantly increased expenses and administrative burdens as a public company in the United States could have an adverse effect on its business, financial condition and results of operations.
  • The initial stockholders of Clean Earth, including its officers and directors, have interests in the Business Combination that are different from, or in addition to, the interests of Clean Earth's other stockholders and warrant holders in recommending that stockholders vote in favor of approval of the Business Combination and approval of the other proposals.
  • Both Clean Earth and Alternus will incur significant transaction costs in connection with the Business Combination.
  • The consummation of the Business Combination is subject to a number of conditions, including approval of Clean Earth's stockholders, and if those conditions are not satisfied or waived, the definitive agreement for the Business Combination may be terminated in accordance with its terms and the Business Combination may not be completed.
  • Our management team has limited experience managing a publicly traded company in the United States and may not successfully or effectively manage the transition of the predecessor businesses to a public company in the United States following the Business Combination.
  • The ability of Clean Earth's stockholders to exercise redemption rights with respect to a large number of outstanding shares of common stock could limit the amount of cash available to the Combined Company for growth and reduce the Combined Company's public "float."
  • If the Business Combination's benefits do not meet the expectations of investors or securities analysts, the market price of Clean Earth's securities or, following the consummation of the Business Combination, the value of the Combined Company's securities, may decline.
  • There can be no assurance that the Combined Company's securities will be approved for listing on the chosen stock exchange or that the Combined Company will be able to comply with the continued listing standards of such stock exchange.
  • Legal proceedings in connection with the Business Combination, the outcomes of which are uncertain, could delay or prevent the completion of the Business Combination.
  • Following the completion of the Business Combination, the majority of the Combined Company's shares will be owned by an Irish company publicly listed on Euronext Growth (Oslo), which could adversely affect the ability of stockholders to exercise control and the public float, trading volume and market price of the Combined Company's common stock.
