Risk Factors Risk Factors The below list of risk factors has been prepared solely for purposes of the proposed private placement transaction (the “Priv ate Placement”) as part of the proposed transaction, and solely for potential investors in the Private Placement, and not for any other purpose. All references to “ ZincFive ,” the “Company,” “we,” “us” or “our” refer to the business of ZincFive , Inc. and its consolidated subsidiaries. The risks presented below are certain of the general risks related to the business of the Company, the Private Placement and the proposed business combination (the “Business Combination”) between the Company and Spark I Acquisition Corporation (“Spark”), an d 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 Spark, with the U.S . Securities and Exchange Commission (“SEC”), including the documents filed or furnished in connection with the proposed transactions between the Company and Spark. The ri sks 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 securit ies of the Company and Spark and the proposed transactions between the Company and Spark, and may differ from and be more extensive than those presented below. Investing i n s ecurities (the “Securities”) to be issued in connection with the Business Combination involves a high degree of risk. You should carefully consider these risks and uncert ain ties, 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 y our own financial and legal advisors concerning the risks and suitability of an investment in the Private Placement, before making an investment decision. There are many risks t hat 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, fin ancial condition and/or operating results could be materially and adversely harmed. Additional risks and uncertainties not currently known or those currently viewed to be immat eri al 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 va lue of the Company’s equity securities may decline, and any investor in the offering may lose all or part of its investment. Risks Related to Our Business Capital Requirements and Financial Position. We have a history of operating losses and may not achieve or sustain profitability in the future. We will require substantial a dditional capital to pursue our business objectives and respond to business opportunities, challenges or unforeseen circumstances, and we cannot be sure that additional financing will be available. As we endeavor to expand our business, we will incur significant costs and expenses, which could outpace our cash res erves. Unfavorable conditions or disruptions in the capital and credit markets may adversely impact business conditions and the availability of credit. Our indebtedness coul d a dversely affect our business, financial condition and results of operations and restrict us in ways that limit our flexibility in operating our business. 36

Risk Factors (Cont’d) Our Business and Industry. Failure to deliver the benefits offered by our technologies, or the emergence of improvements to competing technologies, coul d r educe demand for our products and harm our business. Traditional lithium - ion technologies may have certain actual or perceived advantages over ou r technology, which could affect demand for our products. A decline in lithium prices or other improvements in lithium - ion battery technology may result in increased competitio n from traditional lithium - ion batteries and adversely affect the demand for our products. International trade policies, including tariffs, sanctions and trade barriers m ay adversely affect our business, financial condition, results of operations and prospects. Our business has and is expected to continue to have significant customer concentration. Ba cklog may not be realized or may not result in profits and may not accurately represent future revenue. Manufacturing. Our future success depends in part on our ability to increase our production capacity, and we may not be able to do so in a c ost - effective manner. If we elect to expand our production capacity by constructing or leasing one or more new manufacturing facilities, we may encounter challeng es relating to the construction, management and operation of such facilities. We may experience delays, disruptions, or quality control problems in our manufacturing operati ons . Defects, field failures, or performance problems in our products could result in loss of customers, reputational damage, and decreased revenue. We may also face warranty, ind emn ity, and product liability claims that may arise from defective products or field failures. Competition. We operate in highly competitive energy industries, and are subject to pricing pressure and increasing competition. Many of o ur competitors and potential competitors have substantially greater financial, marketing, personnel and other resources than we do, and if we do not compe te effectively, our competitive positioning and our operating results will be harmed. Future Growth. If we fail to manage our recent and future growth effectively, we may be unable to execute our business plan, maintain high l ev els of customer service, or adequately address competitive challenges. Our planned expansion into new geographic markets or new product lines or services co uld subject us to additional business, financial, and competitive risks. Our ability to proceed with projects under development and complete construction of projects on schedu le and within budget are subject to contractual, technology, operating and commodity risks as well as market conditions that may affect our operating results. Demand for our pro ducts depends on the continued growth of energy - reliant infrastructure, including infrastructure to support demand for AI, which has seen rapid growth in recent years an d if demand for such infrastructure does not continue to grow at similar or higher rates, it may have a material adverse effect on our business, financial condition, oper ati ng results and prospects for future growth. Strategic Partners. The execution of our strategy to expand into new markets through strategic partnerships, joint ventures and licensing arrange men ts is in a very early stage and is also subject to various risks which could adversely affect our business and future prospects. 37

Risk Factors (Cont’d) Third Parties. We depend on third - party suppliers for the development and supply of key raw materials and components for our energy storage pr oducts. We also depend on vendors for the shipping of our energy storage products. Quality issues or delays in our supply or delivery chain and shipmen ts could harm our ability to manufacture, supply and commercialize our energy storage products. International Operations. Because our success depends, in part, on our ability to expand sales internationally, our business will be susceptible to ris ks associated with international operations. We currently rely on our manufacturing facility in China for the production of components of our pr odu cts, and a significant disruption in the operation of our manufacturing facility in China, political unrest in China, tariffs, impact of outbreaks of health epidemics, or changes in social, political, trade, health, economic, environmental, or climate - related conditions or in laws, regulations and policies governing foreign trade could materially and adversely affect our business, financial condition and results of operations. Intellectual Property. If we are unable to obtain and maintain patent protection for our products and technology, or if the scope of the patent prot ec tion obtained is not sufficiently broad or robust, our competitors could develop and commercialize products and technology similar or identical to ou rs, and our ability to successfully commercialize our products and technology may be adversely affected. Moreover, our trade secrets could be compromised, which could cause us to lose the competitive advantage resulting from these trade secrets. Legal, Regulatory and Government. The nature of our business exposes us to potential legal proceedings or claims that could adversely affect our operating resu lt s. These claims could conceivably exceed the level of our liability insurance coverage. We are subject to requirements relating to environmen tal and safety regulations and environmental remediation matters, which could adversely affect our business, results of operation and reputation. We are subject to govern men tal export and import controls and trade and economic sanctions that could impair our ability to compete in global markets and subject us to liability if we are not in fu ll compliance with applicable laws and other controls. In addition, many of our customers and prospective customers rely on federal, state and local government incentives, the reducti on of which could reduce demand for our products. Further, investments in, or incentives granted to, our competitors by governmental entities could put us at a competitive dis adv antage. Risks Related to the Private Placement Capital Raise. There can be no assurance that we will be able to raise the anticipated ~$100 million in the Private Placement, or that the a mou nt of funds raised in the Private Placement will be sufficient to consummate the Business Combination or for use by the combined company following the Business Co mbination (the “Combined Company”). Voting Power. The issuance of shares of the Combined Company’s securities in connection with the Private Placement will dilute the voting p owe r of the Combined Company’s shareholders. 38

Risk Factors (Cont’d) Risks Related to the Business Combination Transaction Costs. Both Spark and we will incur significant transaction costs in connection with the Business Combination. Contingencies of Business Combination. The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisfied o r waived, the Business Combination Agreement may be terminated in accordance with its terms and the Business Combination may not be com ple ted. Key Personnel. The ability to successfully effect the Business Combination and the Combined Company’s ability to successfully operate the bu sin ess thereafter will be largely dependent upon the efforts of certain of our key personnel, all of whom we expect to stay with the Combined Company following th e Business Combination. The loss of such key personnel could negatively impact the operations and financial results of the combined business. Redemption. If a significant number of shares of Spark’s common stock is elected to be redeemed in connection with the Business Combinati on, the stock ownership of the Combined Company will be highly concentrated, which will reduce the public “float” and may have a depressive effect on the ma rke t price of the common stock of the combined company. Redemptions would also reduce the amount of capital available to the Combined Company following the Business Combina tio n. If accepting all properly submitted redemption requests would cause minimum cash to be less than any amount necessary to satisfy a closing condition, Spark may n ot proceed with such redemptions and Business Combination. Value of Securities. If the Business Combination’s benefits do not meet the expectations of investors or securities analysts, the market price of Spa rk’s securities or, following the consummation of the Business Combination, the value of the Combined Company’s securities, may decline. Stock Exchange Approval. There can be no assurance that the Combined Company’s securities will be approved for listing on the chosen stock exchange or th at the Combined Company will be able to comply with the continued listing standards of such stock exchange. Conflicts of Interest. Some of Spark’s officers and directors may have conflicts of interest that may influence or have influenced them to support o r a pprove the Business Combination without regard to your interests or in determining whether we are an appropriate target for Spark’s initial busin ess combination. Legal Proceedings. Legal proceedings in connection with the Business Combination, the outcomes of which are uncertain, could delay or prevent th e c ompletion of the Business Combination. 39

Risk Factors (Cont’d) Compliance with Laws. Changes in laws or regulations or interpretation and application of such laws and regulation, or a failure to comply with any l aws and regulations, may adversely affect us and the Combined Company’s business, including Spark, and our ability to consummate the Business Combinat ion , and results of operations. 40
