Rubicon’s and Combined Co’s actual results may differ from their expectations, estimates and projections and consequently, you should not rely on these forward - looking statements as predictions of future events.

These forward - looking statements include, without limitation, Rubicon’s and SPAC’s expectations with respect to future performance. These forward - looking statements also involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Factors that may cause such differences include, but are not limited to: (1) the outcome of any legal proceedings that may be instituted in connection with any proposed business combination; (2) the inability to complete any proposed business combination; (3) delays in obtaining, adverse conditions contained in, or the inability to obtain necessary regulatory approvals or complete regulatory reviews required to complete any business combination; (4) the risk that any proposed business combination disrupts current plans and operations; (5) the inability to recognize the anticipated benefits of any proposed business combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain key employees; (6) costs related to the any proposed business combination; (7) changes in the applicable laws or regulations; (8) the possibility that Rubicon or Combined Co may be adversely affected by other economic, business, and/or competitive factors; (9) the impact of the global COVID - 19 pandemic; and (10) other risks and uncertainties separately provided to you and indicated from time to time in filings and potential filings by Rubicon, SPAC and Combined Co with the U.S. Securities and Exchange Commission (the “SEC”). Rubicon and SPAC caution that the foregoing list of factors is not exclusive and not to place undue reliance upon any forward - looking statements, including projections, which speak only as of the date made. Rubicon and SPAC undertake no obligation to and accept no obligation to release publicly any updates or revisions to any forward - looking statements to reflect any change in their expectations or any change in events, conditions or circumstances on which any such statement is based. Industry, Market Data and Partnerships In this presentation, Rubicon and SPAC rely on and refer to certain information and statistics regarding the markets and industries in which Rubicon competes . Such information and statistics are based on management’s estimates and/or obtained from third - party sources, including reports by market research firms and company filings . While Rubicon and SPAC believe such third - party information is reliable, there can be no assurance as to the accuracy or completeness of the indicated information . Rubicon and SPAC have not independently verified the accuracy or completeness of the information provided by the third - party sources . This Presentation contains descriptions of certain key business partnerships with Rubicon. These descriptions are based on the Rubicon management team’s discussion with such counterparties, certain non - binding written agreements and the latest available information and estimates as of the date of this Presentation. These descriptions are subject to negotiation and execution of definitive agreements with certain of such counterparties which have not been completed as of the date of this Presentation.

2 Use of Projections This Presentation contains projected financial information with respect to Rubicon. Such projected financial information constitutes forward - looking information, and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. Further, illustrative presentations are not necessarily based on management’s projections, estimates, expectations, or targets but are presented for illustrative purposes only. Rubicon’s independent auditors have not 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. The assumptions and estimates underlying such financial forecast information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties. See “Forward - Looking Statements” above. Actual results may differ materially from the results contemplated by the financial forecast information contained in this Presentation, and the inclusion of such information in this Presentation is not intended, and should not be regarded, as a representation by any person that the results reflected in such forecasts will be achieved. Further, the metrics referenced in this Presentation regarding select aspects of Rubicon’s operations were selected by SPAC and Rubicon on a subjective basis. Such metrics are provided solely for illustrative purposes to demonstrate elements of Rubicon’s business, are incomplete, and are not necessarily indicative of Rubicon’s performance or future performance or overall operations. There can be no assurance that historical trends will continue. 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”), EBITDA adjusted for various non - recurring items (“Adjusted EBITDA”), adjusted gross profit 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 may occur in the future and are significant in understanding and assessing Rubicon’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income or other measures of profitability under GAAP. You should be aware that Rubicon’s presentation of these measures may not be comparable to similarly - titled measures used by other companies. Rubicon believes these non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Rubicon’s financial condition and results of operations. Rubicon 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 Rubicon, and in comparing Rubicon’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 Rubicon believes are the most directly comparable measure evaluated in accordance with GAAP. This Presentation also includes certain projections of non - GAAP financial measures. Rubicon does not provide reconciliations of Adjusted Gross Profit or Adjusted Gross Profit Margin (the result obtained from dividing Adjusted Gross Profit by revenue) to gross profit or gross profit margin or EBITDA, Adjusted EBITDA, or Adjusted EBITDA margin (the result obtained from dividing Adjusted EBITDA by revenue) to net income on a forward - looking basis because Rubicon is unable to reliably forecast the amount or significance of certain items required to develop meaningful projections of the comparable GAAP financial measures without unreasonable efforts. These items include gains or losses on sale or consolidation transactions, accelerated depreciation or amortization, impairment charges, gains or losses on retirement of debt, variations in effective tax rate, and fluctuations in net working capital, which are difficult to predict and estimate and are primarily dependent on future events, but which are excluded from Rubicon’s calculations of these non - GAAP measures. We expect the variability of these items could have a significant impact on our reported GAAP financial results. Trademarks This Presentation contains trademarks, service marks, trade names and copyrights of Rubicon and other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this Presentation may be listed without the TM, SM © or ® symbols, but Rubicon and SPAC will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights. Further, third - party logos included in this Presentation may represent past or present vendors or suppliers of materials and/ or products to Rubicon for use in in connection with its business and/or installation and sale of solar systems or may be provided simply for illustrative purposes only. Inclusion of such logos does not necessarily imply affiliation with or endorsement by such firms or businesses. There is no guarantee that either SPAC or Rubicon will work, or continue to work, with any of the firms or businesses whose logos are included herein in the future.

Asset heavy, landfill - based model makes ~50% of EBITDA on frequency and tonnage disposed in the landfill Landfill incentives outweigh recycling incentives Example: Waste Management’s recycling rate of 13% is approximately half the industry average Disjointed, antiquated technology with no visibility into waste data Lack of competition results in inflated pricing for all 12 Old World Approach to Waste Management Little has changed since the late 18 th century; the industry is ripe for disruption Rubicon’s Approach to Waste Management Data - centric approach to waste management is powering sustainability for businesses and cities Digital, cloud - based model’s utilization of lower - cost resources results in more efficient use of growth capital Rubicon monetizes commodities diverted from landfills, incentivizing recycling efforts and reducing total customer waste spend Holistic audit of customer waste streams results in increased transparency and reduced costs Rubicon’s Integrated waste management platform changes how we think about waste Source: Annual Reports; Earnings Calls; Waste Business Journal

Waste is One of the Few Remaining Industries on the Disruption Curve 17 Model centered around real estate assets Inability to adapt in digital world Poor customer experience, excessive and hidden fees Structured to ignore significant capacity from independents Vulnerable to growing awareness of, and opposition to, landfill Not structured to capture and monetize the wealth of data potentially at their disposal Traditional Model - Offline Acutely positioned for disruption and - more importantly - customer disintermediation Reimagined Customer Experience Rubicon is a decade ahead of the sector and is actively disintermediating the incumbents to become the nexus between customer and hauler Built on a foundation of technology / online buying Optimized logistics Consumer - centric approach Business revolves around users Data - driven Ability to expand into adjacent markets
