ZEO ENERGY

This presentation (“Presentation”) contains, and oral comments related to it may contain, “forward - looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward - looking statements can be identified by words such as “anticipate,” “intend,” “plan,” “goal,” “seek,” “believe,” “project,” “estimate,” “expect,” “strategy,” “future,” “likely,” “may,” “should,” “will” and similar references to future periods. Examples of forward - looking statements include, among others, statements we make regarding: (a) our ability to grow and manage growth profitably, maintain relationships with customers and suppliers and retain key personnel; (b) our projected financial information, anticipated growth rate and market opportunity; (c) our success in retaining or recruiting our employees, sales representatives, officers, or directors; (d) competition from electric utilities and other companies in the industry; (e) factors relating to the business, operations and financial performance of Zeo, including market conditions and global and economic factors beyond Zeo’s control; (f) Zeo’s implementation and momentum of business plans or strategies, expectations regarding market share, market penetration, financing activities, loan and lease financing, financing capacity, product mix, and ability to manage cash flow and liquidity; (g) our ability to benefit from partnerships, new technologies, and pilot programs, including lease or other programs for financing solar system installations; (h) changes in general economic conditions, including unemployment, inflation (including the announcement or impact of tariffs) or deflation, financial institution disruptions and geopolitical conflicts such as the conflict between Russia and Ukraine and the conflict in the Gaza Strip; (i) government economic incentives to the renewable energy market; (j) our ability to issue equity or equity - linked securities or obtain debt financing; (k) the demand for renewable energy and solar - generated energy; (l) impacts of climate change, changing weather patterns, conditions, and natural disasters; (m) costs of energy system and storage components and raw materials; (n) our ability to manage suppliers, inventory, and workforce; (o) the quality or performance of the systems we sell and install; (p) other factors outside of Zeo’s control such as macroeconomic trends, bank failures, and public health emergencies. Forward - looking statements are neither historical facts nor assurance or guaranty of future performance. Instead, they are based only on our current beliefs, expectations, and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward - looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward - looking statements. Therefore, you should not rely on any of these forward - looking statements. In light of the significant uncertainties in these forward - looking statements, you should not regard these statements as a representation or warranty by Zeo, its directors, officers or employees or any other person, that Zeo will achieve its objectives and plans in any specified time frame, or at all. We undertake no obligation to update or revise any forward - looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. You should not take any statement regarding past trends or activities as representation that the trends or activities will continue in the future. Accordingly, you should not put undue reliance on these statements. Risks and uncertainties that could cause Zeo’s financial results and condition to differ materially from those expressed or implied by forward - looking statements and which you should carefully consider include those identified below and others described in reports that we have filed and will file with the U.S. Securities and Exchange Commission from time to time, including those detailed in the “Summary Risk Factors” and Section 1.A “Risk Factors” section of our 10 - K statement for the year 2024 filed on May 27, 2025. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward - looking statements. A non - exhaustive list of some of these risks and uncertainties include the following: (a) the solar and broader energy industry is evolving and additional demand for solar energy systems or storage may not develop to the size or at the rate expected; (b) a material reduction in the price of electricity charged by electric utilities or other electricity providers would harm Zeo’s financial condition and results; (c) sales and installation of energy systems depend on suitable meteorological and environmental conditions which may change; (d) our business has benefited from declining costs of components and may be harmed if the cost of such components stabilize or increase in the future, including due to tariffs or similar costs; (e) the success of our relationships with equipment suppliers, contractors and sales dealers; (f) Zeo depends on a limited number of suppliers of solar and other energy system components and technologies to adequately meet its demands; (g) our ability to manage growth effectively; (h) technical and regulatory limitations regarding the interconnection of solar energy or storage systems to the electrical grid may delay interconnections and customer in - service dates; (i) our business is concentrated in certain markets, putting us at risk of region - specific disruptions, including hurricanes or other extreme weather events; (j) Zeo’s expansion into new sales channels and markets could be costly and time - consuming; (k) our business depends on the availability of utility rebates, tax credits and other incentives that may be adversely affected by changes in laws or policies; (l) we rely on certain utility rate policies, such as net metering, to offer competitive pricing to customers, and such policies may change; (m) utility policies, government laws, and regulations may change; (n) our management team has limited experience managing a public company, and regulatory compliance obligations may divert its attention from the day - to - day management of our businesses; (o) we have identified material weaknesses in our internal controls over financial reporting. If we are unable to remediate these material weaknesses, or if we otherwise fail to maintain effective internal controls over financial reporting, we may not be able to accurately or timely report our financial position or results of operations; (p) Nasdaq may delist Zeo’s securities from trading on its exchange; (q) a significant portion of the total outstanding shares of Class A Common Stock are restricted from immediate resale; this could negatively affect the market price of Class A Common Stock, even if Zeo’s business is doing well; (r) An active, liquid market for Zeo’s securities may not develop, which would adversely affect the liquidity and price of Zeo’s securities; and (s) Zeo Warrants are exercisable for Zeo Common Stock, and if exercised, would increase the number of shares eligible for future resale in the public market and result in dilution to the stockholders of Zeo. 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 Zeo’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 Zeo’s presentation of these measures may not be comparable to similarly titled measures used by other companies. Zeo believes these non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Zeo’s financial condition and results of operations. Zeo believes 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 Zeo, and in comparing Zeo’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 Zeo believes are the most directly comparable measure evaluated in accordance with GAAP. 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. Additional Information and Where to Find It .
