Plum and Sakuu disclaim any duty to update the information contained in this presentation. Forward-Looking Statements This presentation contains certain forward-looking statements within the meaning of the federal securities laws with respect to the proposed transaction between Sakuu and Plum. These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions. These forward-looking statements include, but are not limited to, statements regarding Sakuu’s expected technology and product offerings, Sakuu’s ability to produce its modules and printing platforms at a commercial level or obtain licensing agreements for its battery technology, the availability of equity or debt financing on acceptable terms, if at all, and the capitalization of Sakuu after giving effect to the proposed business combination. These statements are based on various assumptions, whether or not identified in this press release, and on the current expectations of Sakuu’s and Plum’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied upon by any investors as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and are subject to risks and uncertainties that may cause Sakuu’s and Plum’s activities or results to differ significantly from those expressed in any forward-looking statement, including changes in domestic and foreign business, market, financial, political and legal conditions; the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect Sakuu or the expected benefits of the proposed business combination; failure to obtain the approval of the equity holders of Sakuu or Plum; failure to realize the anticipated benefits of the proposed business combination; risks related to the rollout of Sakuu’s business and the timing of expected business milestones; the effects of competition on Sakuu’s business; supply shortages in the materials necessary for the production of Sakuu’s modules and printing platforms; the inability of Sakuu to obtain licensing agreements for its technology; the amount of redemption requests made by Plum’s public equity holders. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. Many factors could cause actual future events to differ materially from the forward-looking statements in this communication. There may be additional risks that neither Sakuu or Plum presently know or that Sakuu and Plum currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. You should carefully consider the risks and uncertainties described in the “Risk Factors” section of Plum’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, the registration statement on Form S-4 and other documents filed by Plum from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and Sakuu and Plum assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. Neither Sakuu nor Plum gives any assurance that either Sakuu or Plum will achieve its expectations. Industry and Market Data In this presentation, Plum and Sakuu rely on and refer to publicly available information and statistics regarding market participants in the sectors in which Sakuu competes and other industry data. Any comparison of Sakuu to the industry or to any of its competitors is based on this publicly available information and statistics and such comparisons assume the reliability of the information available to Sakuu. Sakuu obtained this information and statistics from third-party sources, including reports by market research firms and company filings. While Sakuu believes such third-party information is reliable, there can be no assurance as to the accuracy or completeness of the indicated information. Neither Sakuu nor Plum has independently verified the information provided by the third-party sources. Trademarks This presentation may contain trademarks, service marks, trade names and copyrights of 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 Plum and Sakuu 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.

Disclaimers (continued) Private Placement The securities to which this presentation relates have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any other jurisdiction. Sakuu is offering securities to which this presentation relates in reliance on exemptions from the registration requirements of the Securities Act and other applicable laws. These exemptions apply to offers and sales of securities that do not involve a public offering. The securities have not been approved or recommended by any federal, state or foreign securities authorities, nor have any of these authorities passed upon the merits of this offering or determined that this presentation is accurate or complete. Any representation to the contrary is a criminal offense. Financial and Other Information The financial information contained in this presentation has been taken from or prepared based on the historical financial statements of Sakuu for the periods presented. An audit of these financial statements is in process. Accordingly, such financial information and data may not be included in, may be adjusted in or may be presented differently in any registration statement to be filed with the SEC by Plum in connection with the Transaction. Sakuu has not yet completed its closing procedures for the three months ended December 31, 2022. This presentation contains certain estimated preliminary financial results and key operating metrics for the year ended December 31, 2022. This information is preliminary and subject to change. As such, Sakuu’s actual results may differ from the estimated preliminary results presented here and will not be finalized until the completion of its year-end accounting procedures. Non-GAAP Financial Measures This presentation includes projections of certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to EBITDA and EBITDA Margin. 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 Sakuu’s financial results. Therefore, these measures should be considered in isolation or as an alternative to other measures of profitability or performance under GAAP. You should be aware that Sakuu’s presentation of these measures may not be comparable to similarly-titled measures used by other companies. Sakuu believes that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Sakuu’s financial condition and results of operations. Sakuu believes that the use of these non- GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and in comparing Sakuu’s financial measures with other 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 expenses and income are excluded or included in determining these non-GAAP measures. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, Sakuu is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included, and no reconciliation of the forward-looking non-GAAP financial measures is included. For the same reason, Sakuu is unable to address the probable significance of the unavailable information, which could be material to future results. Use of Projections This presentation also contains certain financial forecasts, including projected revenue. Neither Plum’s nor Sakuu’s independent auditors have studied, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. These projections are for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. In this presentation, certain of the above-mentioned projected information has been provided for purposes of providing comparisons with historical data. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Projections are inherently uncertain due to a number of factors outside of Plum’s or Sakuu’s control. Accordingly, there can be no assurance that the prospective results are indicative of future performance of the combined company after the Transaction or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. Participation in Solicitation Plum and Sakuu and their respective directors and executive officers, under SEC rules, may be deemed to be participants in the solicitation of proxies of Plum’s shareholders in connection with the Transaction. Investors and security holders may obtain more detailed information regarding the names and interests in the Transaction of Plum’s directors and officers in Plum’s filings with the SEC, including Plum’s Form S-1. To the extent that holdings of Plum’s securities have changed from the amounts reported in Plum’s Form S-1, such changes have been or will be reflected on Statements of Change in Ownership on Form 4 filed with the SEC. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of proxies to Plum’s shareholders in connection with the Transaction will be set forth in the proxy statement/prospectus on Form S-4 for the Transaction, which is expected to be filed by Plum with the SEC. Investors and security holders of Plum and Sakuu are urged to read the proxy statement/prospectus and other relevant documents that will be filed with the SEC carefully and in their entirety when they become available because they will contain important information about the Transaction. Investors and security holders will be able to obtain free copies of the proxy statement/prospectus and other documents containing important information about Plum and Sakuu though the website maintained by the SEC at www.sec.gov. Copies of the documents filed with the SEC by Plum can be obtained free of charge by directing a written request to Plum Acquisition Corp. I, 2021 Fillmore Street #2089, San Francisco, CA 94115.

Risks Risks Related to Sakuu’s Business · The battery market is intensely competitive. Competitors include new entrants and established companies, many of which have significantly greater resources than Sakuu does. Sakuu’s products must compete with advances in new battery chemistries and manufacturing methods as well as continued improvements in conventional batteries and battery anodes. · If Sakuu’s batteries fail to perform as expected, its ability to develop, market, and sell its batteries would be adversely affected. · Sakuu may not succeed in developing its additive manufacturing platform technology such that the technology meets Sakuu’s requirements for quality, yield, throughput and other performance metrics. · A portion of Sakuu’s anticipated revenue is subjected to non-binding purchase orders, which may not result in the expected, or any, sales. · Sakuu has significant customer concentration, with a limited number of customers accounting for a substantial portion of anticipated revenue. · Sakuu may not succeed in retaining and attracting key employees, particularly technical talent, needed to operate and build its business successfully. · Sakuu may not succeed in advancing its battery technologies to enable further improvements in energy density, cycle life, safety and other characteristics. Failure to do so could limit its market opportunities, ability to compete and the prices Sakuu can charge for its products. · Sakuu may encounter delays and technical obstacles in developing new battery products, such as different cell formats, to meet varied market requirements. · Sakuu’s future sales opportunities depend in part on the growth of markets for lithium metal battery cells. These markets may develop slower or at a size that is less than expected, to the extent they develop at all. · Sakuu depends on certain third-parties, including its partnership with its manufacturer of the Cypress Li-Metal battery, in producing Sakuu’s products. · Sakuu may require additional capital to support business growth, and this capital might not be available on commercially reasonable terms or at all. · Sakuu relies on complex machinery for its operations and production involves a significant degree of risk and uncertainty in terms of operational performance and costs. · Sakuu may not be able to establish supply relationships for necessary materials, components or equipment or may be required to pay more than anticipated for components or equipment, which could negatively impact Sakuu’s business. · Sakuu’s future growth and success depend on its ability to effectively sell to a wide variety of customers across a deconsolidated industry. · lf existing customers do not make subsequent purchases from Sakuu or renew their contracts with Sakuu, its revenue could decline, and its results of operations would be adversely impacted. · Sakuu may not be able to accurately estimate the future supply and demand for its batteries, which could result in a variety of inefficiencies in its business and hinder its ability to generate revenue. If Sakuu fails to accurately predict its manufacturing requirements, it could incur additional costs or experience delays. · Certain components of Sakuu’s batteries pose safety risks that may cause accidents. Sakuu may be subject to financial and reputational risks due to product recalls and product liability claims, and Sakuu could face substantial liabilities that exceed its resources. · Developments in alternative technology or other fossil fuel alternatives may adversely affect the demand for Sakuu’s battery products. · Sakuu’s operations expose it to litigation and environmental and other legal compliance risks. Compliance with laws and regulations can be expensive, and Sakuu’s failure to comply with these laws and regulations may result in monetary damages and fines, adverse publicity and a material adverse effect on its business. · Sakuu is an early stage company with a history of financial losses and it expects to incur significant expenses and continuing losses for the foreseeable future. · lf Sakuu fails to effectively manage its future growth, it may not be able to market and sell its batteries successfully. · Sakuu relies heavily on its intellectual property portfolio. If Sakuu is unable to protect its intellectual property rights, its business and competitive position would be harmed. Copyright© 2023 Sakuu Corp. All rights reserved. 41

Risks (continued) Risks Related to Being Public Company · Sakuu’s management team has limited experience managing a public company and may not successfully or effectively manage Sakuu’s transition to a public company. · Sakuu’s internal control over financial reporting may not be effective in detecting or preventing material errors at a reasonable level of assurance. Sakuu’s past or future financial statements may not be accurate and Sakuu may not be able to timely report its financial condition or results of operations, which may adversely affect investor confidence in Sakuu and the price of Sakuu’s securities following the business combination. · As with any public company, the combined company may be subject to securities litigation, which is expensive and could divert management’s attention. Risks Related to Plum’s Securities · If the benefits of the business combination do not meet the expectations of investors or securities analysts, the market price of Plum’s securities may decline, either before or after the closing of the business combination. · The combined company will incur significant increased expenses and administrative burdens as a public company, which could have an adverse effect on its business, financial condition and results of operations. · An active trading market for Plum’s Class A ordinary shares may not be available on a consistent basis to provide stockholders with adequate liquidity. The stock price may be extremely volatile, and stockholders could lose a significant part of their investment. · Plum’s Class A ordinary shares may fail to meet the continued listing standards of the Nasdaq Stock Market (“Nasdaq”), and additional shares may not be approved for listing on Nasdaq. · Because Sakuu has no current plans to pay cash dividends for the foreseeable future, you may not receive any return on investment unless you sell your shares for a price greater than that which you paid for them. · If, following the transaction, securities or industry analysts do not publish or cease publishing research or reports about Sakuu, its business, or its market, or if they change their recommendations regarding Sakuu’s securities adversely, the price and trading volume of Sakuu’s securities could decline. General Risks · Economic downturns and political and market conditions beyond Sakuu’s control could adversely affect its business, financial condition and results of operations. · Sakuu is exposed to the risk of natural disasters, political events, health crises such as the global COVID-19 outbreak, war and terrorism and other macroeconomic events, including increased interest rates and inflation, each of which would disrupt its business and adversely affect its results of operations. Risks Related to Plum and the Business Combination · Directors of Plum have potential conflicts of interest in recommending that Plum’s shareholders vote in favor of the adoption of the merger agreement and the business combination, and approval of the other proposals described in the proxy statement/prospectus. · Plum may, in accordance with their terms, redeem unexpired Plum warrants prior to their exercise at a time that is disadvantageous to holders of Plum warrants. · Plum’s founders, directors, officers, advisors and their affiliates may elect to purchase Plum Class A ordinary shares or Plum warrants from public shareholders, which may reduce the public “float” of Plum’s Class A ordinary shares. · Plum’s sponsor has agreed to vote in favor of the business combination, regardless of how Plum’s public shareholder's vote. As a result, a significant portion of Plum’s voting securities outstanding will be contractually obligated to vote in favor of the business combination. · Even if Plum consummates the business combination, there can be no assurance that Plum’s public warrants will be in the money during their exercise period, and they may expire worthless. · The ability of Plum’s shareholders to exercise redemption rights with respect to Plum’s Class A ordinary shares could increase the probability that the business combination would not occur. · The business combination is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all. · Current Plum shareholders will own a smaller proportion of the post-closing company than they currently own of Plum. In addition, following the closing of the business combination, the combined company may issue additional shares or other equity securities without the approval of its shareholders, which would further dilute their ownership interests and may depress the market price of its shares.
