Disclaimer (cont’d) 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, earnings before interest, taxes, depreciation and amortization (“EBITDA”) and EBITDA before certain bad debt expenses and management addback of stock based compensation expenses (“Adjusted EBITDA” or “Adj EBITDA”) and certain ratios and other metrics derived therefrom. Note that other companies may calculate these non-GAAP financial measures differently, and, therefore, such financial measures may not be directly comparable to similarly titled measures of other companies. Further, 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 Sunergy’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 SPAC’s and Sunergy’s presentation of these measures may not be comparable to similarly titled measures used by other companies. SPAC and Sunergy believe these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Sunergy’s financial condition and results of operations. SPAC and Sunergy 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 Sunergy, and in comparing Sunergy’s financial measures with those of 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 items of expense and income are excluded or included in determining these non-GAAP financial measures. Please refer to footnotes where presented on each page of this Presentation or to the tables therein for a reconciliation of these measures to what Sunergy believes are the most directly comparable measure evaluated in accordance with GAAP. Reconciliation of historical non-GAAP measures to comparable GAAP measures are provided on page 41. Certain monetary amounts, percentages and other figures included in this Presentation have been subject to rounding adjustments. We expect the variability of these items could have a significant impact on our reported GAAP financial results. Certain other amounts that appear in this Presentation may not sum due to rounding. In connection with the contemplated filing by SPAC of a preliminary and definitive proxy statement / prospectus included in a registration statement on Form S-4 with respect to the Transaction and in the course of the review by the SEC of such preliminary proxy statement / prospectus, SPAC may make changes to the information presented in this Presentation, including, without limitation, the description of Sunergy’s business and the financial information and other data included in this Presentation. Comments by the SEC on information in the preliminary proxy statement / prospectus may require modification or reformulation of the information we present in this Presentation, and any such modification or reformulation could be significant. In particular, we note that the SEC has adopted certain rules regarding the use of EBITDA and other financial measures that do not comply with GAAP in the United States, which rules will be applicable to the preliminary and definitive proxy statement / prospectus expected to be filed with respect to the Transaction.

Appendix

Summary Risk Factors All references to “we,” “us” and “our” and “Sunergy” refer to the business and operations of Sunergy prior to the consummation of the proposed Business Combination or to the business and operations of Newco following the Business Combination, as applicable. The risks listed below are certain of the general risks related to the business of the Sunergy, ESGEN and Newco and the Business Combination between them, and this list is not exhaustive. The list below has been prepared solely for the purpose of inclusion in this presentation and not for any other purpose. These risks are based on certain assumptions made Sunergy and ESGEN which may later prove to be incorrect or incomplete. Risks relating to the business of the Sunergy and Newco, the Business Combination and ESGEN will be disclosed in future documents filed or furnished by ESGEN with the SEC, including documents filed or furnished in connection with the proposed transactions between Sunergy and ESGEN. The risks presented in such filings will be consistent with those that would be required for a public company in their SEC filings, including with respect to the business and securities of Sunergy and ESGEN and the proposed transactions between them, and may differ significantly from, and be more extensive than, those presented below. Risks Related to the Solar Industry The solar energy industry is an emerging market which is constantly evolving and additional demand for solar energy systems may not develop to the size or at the rate we expect. We face competition from electric utilities, retail electric providers, independent power producers and renewable energy companies. A material reduction in the retail price of electricity charged by electric utilities or other retail electricity providers would harm our business, financial condition and results of operations. Sales and installation of solar energy systems depends heavily on suitable meteorological and environmental conditions. If meteorological or environmental conditions are unexpectedly unfavorable, the electricity production from our solar service offerings may be below our expectations, and our ability to timely deploy new systems may be adversely impacted. Climate change may have long-term impacts on our business, our industry, and the global economy. Our business has benefited from the declining cost of solar energy system and energy storage system components and may be harmed to the extent the cost of such components stabilize or increase in the future.

Summary Risk Factors (Cont’d) Risks Related to Sunergy’s Operations We may be unable to sustain our level of profitability in the future. Our growth depends in part on the success of our relationships with third parties, including our equipment suppliers, contractors and dealers, including dealers who market to customers and bring the resulting solar contracts to us for fulfillment. We and our contractors depend on a limited number of suppliers of solar energy system components and technologies to adequately meet demand for our solar energy systems. Due to the limited number of suppliers in our industry, the acquisition of any of these suppliers by a competitor or any shortage, delay, price change, imposition of tariffs or duties or other limitation in our or our contractors’ ability to obtain components or technologies we use could result in sales and installation delays, cancelations and loss of customers. We and our suppliers and contractors are subject to risks associated with construction, cost overruns, delays, customer cancellations, regulatory compliance, and other contingencies, any of which could have a material adverse effect on our business and results of operations. If we fail to manage our recent and future growth effectively, we may be unable to execute our business plan, maintain high levels of customer service, or adequately address competitive challenges. The execution of our growth strategy is dependent upon the continued availability of third-party financing arrangements for our customers’ purchases and is affected by general economic conditions and other factors. The COVID-19 pandemic, including its variants, has had, and it, along with other future pandemics, could continue to have an adverse impact on our business, operations, and the markets and communities in which we operate. The cost of maintenance or repair of solar energy systems or energy storage systems throughout the period for which we have offered warranties, or during the term of any maintenance and repair agreements we enter into, or the removal of solar energy systems at the end of the term of certain types of agreements, may be higher than projected today and adversely affect our financial performance and valuation. Problems with product quality or performance may lower the residual value of our solar energy systems and may damage our market reputation and cause our financial results to decline. Warranties provided by the manufacturers of equipment we sell or service may be limited by the ability of a supplier and manufacturer to satisfy its warranty or performance obligations or by the expiration of applicable time or liability limits, which could reduce or void the warranty protections, which could increase our costs and liabilities to customers for the warranties we offer or systems service. Product liability claims against us or accidents could result in adverse publicity and potentially significant monetary damages. Technical and regulatory limitations regarding the interconnection of solar energy systems to the electrical grid may significantly delay interconnections and customer in-service dates, harming our growth rate and customer satisfaction.

Summary Risk Factors (Cont’d) Risks Related to Sunergy’s Operations (Cont’d) Our business is concentrated in certain markets, putting us at risk of region-specific disruptions, including hurricanes or other extreme weather events. Expansion into new sales channels could be costly and time-consuming. As we enter new channels, we could be at a disadvantage relative to other companies who have more history in these spaces. Obtaining a sales contract with a potential customer does not guarantee that the potential customer will not decide to cancel or that we will not need to cancel due to a failed inspection, which could cause us to generate no revenue despite incurring costs and adversely affect our results of operations. We may not realize the anticipated benefits of past or future investments, strategic transactions, or acquisitions, and integration of these acquisitions may disrupt our business and management. Disruptions to our solar production metering and energy storage solutions could negatively impact our revenue and increase our expenses. Our business may be harmed if we fail to properly protect our intellectual property, and we may also be required to defend against claims or indemnify others against claims that our intellectual property infringes on the intellectual property rights of third parties. We rely substantially upon trade secret laws and contractual restrictions to protect our proprietary rights, and, if these rights are not sufficiently protected, our ability to compete and generate revenue could suffer. We use “open source” software in our solutions, which may require that we release the source code of certain software subject to open source licenses or subject us to possible litigation or other actions that could adversely affect our business. Any security breach, unauthorized access or disclosure, or theft of data, including personal information, we, our third party service providers, and suppliers gather, store, transmit, and use, or other hacking, cyber-attack, phishing attack, and unauthorized intrusions into or through our systems or those of our third party service providers, could harm our reputation, subject us to claims, litigation, financial harm, and have an adverse impact on our business. Terrorist or cyberattacks against centralized utilities could adversely affect our business. We may be subject to information technology system failures or network disruptions that could damage our business operations, financial conditions, or reputation. Our rebranding strategy and rebranding expected to follow the Business Combination will involve substantial costs and may not produce the intended benefits if it is not favorably received by our customers. Damage to our brand and reputation or failure to expand our brand would harm our business and results of operations. The loss of one or more members of our senior management or key personnel may adversely affect our operations.

Summary Risk Factors (Cont’d) Risks Related to Sunergy’s Operations (Cont’d) A failure to hire and retain a sufficient number of employees and service providers in key functions would constrain our growth and our ability to timely complete customers’ projects and successfully manage customer accounts. Regulators may limit the type of electricians qualified to install and service our solar and battery systems, or introduce other requirements on our installation other staff, which may result in workforce shortages, operational delays, and increased costs. We have previously been, and may in the future be, subject to regulatory inquiries and litigation, all of which are costly, distracting to our core business and could result in an unfavorable outcome, or a material adverse effect on our business, financial condition, results of operations, or the trading price of Sunergy’s securities. If we are unsuccessful in selling new service and products, including our add-on products, our business, financial condition and results of operations could be adversely affected. Our operating results and our ability to grow may fluctuate from quarter to quarter and year to year, which could make our future performance difficult to predict and could cause our operating results for a particular period to fall below expectations. We may be unable to generate sufficient cash flows or obtain access to external financing necessary to fund our operations and make adequate capital investments as planned due to the general economic environment, cost inflation, and/or the market pressure driving down the average selling prices of our products and services, among other factors. Inflation could result in decreased value from future contractual payments and higher expenses for labor and equipment, which, in turn, could adversely impact our reputation, business, financial condition, cash flows and results of operations. Volatility and increases or fluctuations in interest rates raise our cost of capital and may adversely impact our business. We may incur debt in the future, which could introduce debt servicing costs and risks to our business. We have suppliers that are based outside the United States, which may subject us to additional business risks, including logistical complexity and political instability. Our headquarters and other facilities, as well as the facilities of certain subcontractors and suppliers, are located in regions that are subject to epidemics, earthquakes, floods, fires, and other natural disasters.

Summary Risk Factors (Cont’d) Risks Related to Regulation and Policy Our business currently depends on the availability of utility rebates, tax credits and other benefits, tax exemptions and exclusions, and other financial incentives on the federal, state, and/or local levels. We may be adversely affected by changes in, and application of these laws or other incentives to us, and the expiration, elimination or reduction of these benefits could adversely impact our business. We rely on certain utility rate structures, such as net metering, to offer competitive pricing to customers, and changes to those policies, may significantly reduce demand for electricity from our solar energy systems. Electric utility policies, statutes, and regulations and changes to such statutes or regulations may present technical, regulatory and economic barriers to the purchase and use of our solar energy offerings that may significantly reduce demand for such offerings. We are not currently regulated as a utility under applicable laws, but we may be subject to regulation as a utility in the future or become subject to new federal and state regulations for any additional solar service offerings we may introduce in the future. Changes to the applicable laws and regulations governing direct-to-home sales and marketing may limit or restrict our ability to effectively compete. Increases in the cost or reduction in supply of solar energy system and energy storage system components due to tariffs or trade restrictions imposed by the U.S. government could have an adverse effect on our business, financial condition and results of operations. Any failure to comply with laws and regulations relating to interactions by us or third parties (such as our dealers and contractors) with customers or with licensing requirements applicable to our business could result in negative publicity, claims, investigations and litigation, and may adversely affect our financial performance. Compliance with environmental regulations can be expensive, and noncompliance with these regulations may result in adverse publicity and potentially significant monetary damages and fines. Our business is subject to complex and evolving U.S. and international privacy and data protection laws, rules, policies and other obligations. Many of these laws and regulations are subject to change and uncertain interpretation and could result in claims, increased cost of operations or otherwise harm our business. A failure to comply with laws and regulations relating to our interactions with employees, contractors, or dealers, could result in negative publicity, claims, investigations, and litigation, and adversely affect our financial performance. Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited. A change in our effective tax rate could have a significant adverse impact on our business, and an adverse outcome resulting from examination of our income or other tax returns could adversely affect our results.

Summary Risk Factors (Cont’d) Risks Related to ESGEN and the Business Combination An active trading market for the post-Business Combination Class A common stock, $0.0001 par value per share (the “Newco Common Stock”), may not be available on a consistent basis to provide stockholders with adequate liquidity. The price of the Newco Common Stock may be extremely volatile, and stockholders could lose a significant part of their investment. The Nasdaq or another national securities exchange may not list the Newco Common Stock or other Newco securities on its exchange, which could limit investors’ ability to make transactions in the Newco Common Stock and subject to additional trading restrictions. The Business Combination may not be completed by ESGEN’s business combination deadline in its organizational documents, as amended to date, and ESGEN may fail to obtain an extension of the business combination deadline. ESGEN LLC (ESGEN’s “Sponsor”) and certain of ESGEN’s other initial shareholders have entered into letter agreements to vote in favor of the Business Combination, regardless of how ESGEN’s public shareholders vote. Since the initial shareholders of ESGEN, including our Sponsor and ESGEN’s directors and executive officers, have interests that are different, or in addition to (and which may conflict with), the interests of ESGEN’s shareholders, conflicts of interest exist in determining whether the Business Combination with Sunergy is appropriate as our initial business combination. Such interests include that Sponsor, as well as ESGEN’s directors, will lose their entire respective investments in ESGEN if the Business Combination or another business combination is not completed. The ability of ESGEN’s public shareholders to exercise redemption rights with respect to the outstanding Class A ordinary shares, par value $0.0001 (“Class A ordinary shares”), of ESGEN could increase the probability that the Business Combination will be unsuccessful. We and ESGEN expect to incur significant, non-recurring costs in connection with consummating the Business Combination and related transactions. The Business Combination is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all, which may adversely affect the price of the Class A ordinary shares. Past performance by ESGEN, including its management team and affiliates, may not be indicative of future performance of an investment in ESGEN or the post-combination business. If ESGEN is unable to complete the Business Combination or another initial business combination by the date by which it is required to consummate a business combination pursuant to ESGEN’s organizational documents, as such date may be extended from time to time, ESGEN will cease all operations except for the purpose of winding up and ESGEN will redeem the Class A ordinary shares and liquidate the trust account, in which case ESGEN’s public shareholders may only receive approximately $10.00 per share and the public warrants will expire worthless The fairness opinion obtained by ESGEN’s board of directors from its financial advisor will not be updated to reflect changes in circumstances between signing of the business combination agreement and the completion of the Business Combination.

Summary Risk Factors (Cont’d) Risk Relating to the Post-Business Combination Company and its Common Stock We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to ensure compliance with public company responsibilities and corporate governance practices. If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired. If the Business Combination’s benefits do not meet the expectations of investors, stockholders or financial analysts, the market price of the Newco Common Stock may decline. Our quarterly operating results may fluctuate significantly following the Business Combination. The price of the Newco Common Stock may be volatile and may decline. Unlike ESGEN, Newco will have no trust account to provide downside protection to its investors. There is no guarantee that an active and liquid public market for the Newco Common Stock will develop following consummation of the Business Combination. If, following the Business Combination, securities or industry analysts do not publish or cease publishing research or reports about us, our business, or our market, or if they change their recommendations regarding our common stock adversely, then the price and trading volume of our common stock could decline. Future resales of our outstanding shares may cause the market price of the Newco Common Stock or other securities to drop significantly, even if our business is doing well. A significant portion of our common stock following the Business Combination will be restricted from immediate resale, but may be sold into the market in the future. This could cause the market price of the Newco Common Stock to drop significantly, even if our business is doing well. We may issue some additional Newco Common Stock or other equity securities without shareholder approval in some circumstances, which would dilute post-Business Combination shareholders’ ownership interests and may depress the market price of Newco Common Stock. Our Certificate of Incorporation that will be effective following the completion of the Business Combination will designate specific courts as the exclusive forum for certain litigation that may be initiated by our stockholders, which could limit the ability of our stockholders to obtain a favorable judicial forum for disputes with us or with our directors, officers or employees and may discourage stockholders from bringing such claims. If we fail to comply with the listing requirements of Nasdaq or another national securities exchange, we would face possible delisting, which would result in a limited public market for our securities and make obtaining future debt or equity financing more difficult for us. Because we will become a publicly traded company by means other than a traditional underwritten initial public offering, our post-Business Combination stockholders may face additional risks and uncertainties. We will be an “emerging growth company” and a “smaller reporting company,” and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.
