41 TM Risk Factors This presentation (this “Presentation”) is provided for informational purposes only and has been prepared by Rain Enhancement Technologies, Inc. (the “Company” or “RET”), and Coliseum Acquisition Corp. (“Coliseum” or “SPAC”) to assist interested parties in making their own evaluation with respect to a potential business combination between the Company and Coliseum and related transactions (the “Potential Business Combination”) and for no other purpose. Certain Risks Related to Coliseum and the Company: The risks presented below are certain of the general risks related to Coliseum, as well as the Company’s technology, business, industry and ownership structure and are not exhaustive. These risks speak only as of the date of this presentation and the Company makes no commitment to update such disclosure. The risks highlighted in future filings with the SEC may differ significantly from and will be more extensive than those presented below. • The Company can provide no assurance of the effectiveness and success of ionization rainfall generation technology in increasing precipitation; • The Company has no operating history and has not yet generated any revenues, which makes it difficult to forecast its future results of operations; • The Company expects to incur significant expenses and losses for the foreseeable future; The Company’s growth is dependent upon its ability to successfully acquire customers and support and service its customers; • The Company may not manage growth effectively; • The Company may need additional capital to pursue its business objectives and respond to business opportunities, challenges or unforeseen circumstances, and it cannot be sure that additional financing will be available; • The execution of the Company’s business model, including technology or profitability of its products and services, is not yet proven; • The Company has not demonstrated it can develop rainfall generation technology and faces barriers in replicating meaningful rainfall generation. If the Company cannot successfully overcome those barriers, its business will be negatively impacted and could fail; • The markets for rainfall generation-related products are in nascent stages, and the Company may have limited opportunities to license its technologies or sell its products. A substantial portion of existing ionization rainfall generation technology is derived from public-source intellectual property and as a result the Company may face increased competition; • Even if the Company is successful in developing rainfall generation systems/technology and executing its strategy, other competitors in the industry may achieve technological breakthroughs which render the Company’s technology obsolete or inferior to other products; • If the Company’s platform fails to provide a broad, proven advantage in rainfall generation, its business, financial condition and future prospects may be harmed; • The Company’s operating and financial results relies upon assumptions and analyses developed by third-party trials. If these assumptions or analyses prove to be incorrect, the Company’s actual operating results may be materially different from its forecasted results; • The Company’s estimates of market opportunity and forecasts of revenue generation and market growth, including the ability to meet the supply and demand needs of its customers, may prove to be inaccurate, and even if the market in which it operates achieves the forecasted growth, the Company’s business could fail to grow at similar rates, if at all; • The Company may be unable to successfully manufacture its products or scale up manufacturing of its products in sufficient quantity and quality, in a timely or cost-effective manner, or at all. Unforeseen issues associated with scaling up and constructing rainfall generation systems at commercially viable levels could negatively impact the Company’s financial condition and results of operations; • The Company could suffer disruptions, outages, defects and other performance and quality problems with its rainfall generation systems or the infrastructure on which it relies; • The Company will be dependent on its suppliers and manufacturers, and supply chain issues could delay the introduction of the Company’s product and negatively impact its business and operating results; • The Company’s failure to effectively develop and expand its sales and marketing capabilities could harm its ability to increase its customer base and achieve broader market acceptance of its rain generation technology; • The Company’s operations, projects and prospects are expected to be located in remote areas, and its production, processing and product delivery will rely on the infrastructure and skilled labor being adequate and remaining available; • The Company’s business is dependent on the international market prices of energy and fiberglass, among other materials, which are both cyclical and volatile; • The risk of third parties asserting that the Company is violating their intellectual property rights; • The Company must overcome significant engineering, technology, operations and climatological challenges to deliver consistent results; • Risks relating to the effect of competing technologies, including desalination and chemical-based cloudseeding technology, on the Company’s business; • Risks relating to environmental and weather conditions that are correlated with successful rainfall generation, as well as other ESG-related matters; • The Company may face liability for changing environmental and/or weather conditions, including challenges resulting from excessive rain; • Risks relating to the failures of the Company’s customers, both private and public, to meet payment obligations, including refusal to pay for rainfall generator services that directly or indirectly benefit other nearby parties; • Risks of system securities and data protection breaches; • The Company is highly dependent on its senior technical advisors, and its ability to attract, recruit, and retain senior management, members of its board of directors and other key employees, as well as find qualified labor with the particular skills required to manufacture, operate and advance the platform, is critical to its success; if the Company is unable to retain talented, highly-qualified senior management and other key employees or attract them when needed, it could negatively impact its business; • Risks regarding potential changes in legislative and regulatory environments that may limit the scope of the Company’s marketplace, including land restriction policies and its ability to obtain and maintain permits;

42 TM Risk Factors (Cont’d) • The Company may face political, regulatory and social opposition to its business and activities; • Following the consummation of the Potential Business Combination, Holdco will incur significant increased expenses and administrative burdens as a public company, which could negatively impact its business, financial condition and results of operations; • The Company’s success could be impacted by the inability of the parties to successfully or timely consummate the Potential Business Combination, including the risk that the expected benefits of the Potential Business Combination are not realized; • If the Potential Business Combination's benefits do not its meet the expectations of investors or securities analysts, the market price of Coliseum’s securities or, following the closing, Holdco’s securities, may decline; • Coliseum’s sponsors and directors have potential conflicts of interest in recommending that shareholders vote in favor of approval of the Potential Business Combination and related proposals; • Coliseum’s sponsors have agreed to vote in favor of the Potential Business Combination, regardless of how Coliseum’s public shareholders vote; • If Coliseum is unable to complete the Potential Business Combination with the Company or another business by September 25, 2024, Coliseum will cease all operations except for purposes of winding up, dissolving and liquidating, in which case its public shareholders may only receive approximately $10.00 per share and its warrants will expire worthless. Further, third parties may bring claims against Coliseum, and as a result, the proceeds held in the trust account could be reduced and the per share liquidation price received by shareholders could be less than $10.00 per share; • Coliseum has conducted due diligence to assess the management of the Company’s business but cannot assure you that the Company’s management has all the skills, qualifications or abilities necessary to manage a public company; and the ability of shareholders to exercise redemption rights with respect to a large number of Coliseum’s outstanding public shares could increase the probability that the Potential Business Combination would be unsuccessful and that the shareholders would have to wait for liquidation to redeem their public shares.
